The eyeballs were removed in batches on the 7th and 14th days,and the blood biochemical indexes were detected by automatic biochemical analyzer. 【Results】Of different organic extracts,there was no significant difference in total protein (TP),albumin (ALB),alanine aminotransferase (ALT),aspartate aminotransferase (AST) and urea nitrogen (BUN) between the three concentration treatment groups and the solvent control group (P>0.05);The activity of alkaline phosphatase (ALP) in the high-dose n-butanol extract group was lower than that in the solvent control group,and the difference was statistically significant (P<0.05).【Conclusion】The metabolites of endophytic bacterium RPB-32 of Radix Pseudostellariae heterophylla had no harmful effect on the body. This suggests that it may have the effects of preventing arteriosclerosis,hypertension and diabetes,protecting kidney and liver,inhibiting harmful bacteria such as bacillus coli,and promoting the growth of beneficial bacteria such as Lactobacillus,but its specific mechanism needs to be further studied. 2022 Vol. 39 (6): 804-807 [Abstract] ( 54 ) HTML (1 KB)  PDF (1113 KB)  ( 52 ) 808 Clinical Characteristics of Ex-smokers and Current Smokers with Chronic Obstructive Pulmonary Disease LIU Cong, CHENG Wei, ZENG Yu-qin,et al DOI: 10.3969/j.issn.1671-7171.2022.06.003 【Objective】 To compare the clinical characteristics of current smokers and ex-smokers.【Methods】COPD patients admitted to the respiratory outpatient department of 13 hospitals in Hunan and Guangxi on December 2016 and October 2020 were selected. Information on demographic and sociological data,lung function,and modified Medical Research Council (mMRC) dyspnea scale scores were recorded. A logistic regression analysis was performed to analyze the factors associated with smoking cessation.【Results】Of the total,the mean age was (62.3±8.9) years,and 43.3% were ex-smokers. Compared with the current smokers,the ex-smokers were older,and had heavier dyspnea,more severe airflow limitation,shorter smoking duration,and fewer pack-years. The logistic regression model showed that smoking cessation was negatively correlated with years of smoking,pack-years,but was positively correlated with age,education level,amount smoked,mMRC score,and GOLD grades. 【Conclusion】 Among patients with COPD,more than half still smoked. Ex-smokers differed substantially from continuing smokers in clinical characteristics. Age,educational level,cumulative smoking,disease severity,mMRC score are associated with smoking cessation,and these should be taken into account in smoking-cessation interventions. 2022 Vol. 39 (6): 808-811 [Abstract] ( 75 ) HTML (1 KB)  PDF (1122 KB)  ( 144 ) 812 Analysis of Influencing Factors of Hysteroscopy Combined with Laparoscopy in the Treatment of Cesarean Scar Diverticulum PEI Yi-ming, LIU Run-ping DOI: 10.3969/j.issn.1671-7171.2022.06.004 【Objective】To explore the influencing factors of hysteroscopy combined with laparoscopy in the treatment of cesarean scar diverticulum. 【Methods】A total of 96 patients with cesarean scar diverticulum who underwent hysteroscopy combined with laparoscopy in The First People&apos;s Hospital of Xianyang from April to November 2019 were selected. Six months after operation,they were divided into poor recovery group and good recovery group according to their recovery. The clinical data of body mass index,pregnancy times,hemoglobin (HB),white blood cell (WBC),albumin (ALB) and other levels were compared between the two groups.Multivariate logistic regression was used to analyze the influencing factors of surgical treatment of cesarean scar diverticulum.【Results】 At 6 months after operation,23 cases (23.96%) with diverticulum were found by B-ultrasonography,and were included in the poor recovery group; 73 patients (76.04%) without diverticulum were included in the good recovery group. The body mass index,the number of cesarean section,the depth of diverticulum and the proportion of posterior uterus in the poor recovery group were significantly higher than those in the good recovery group,and the level of Hb was lower than that in the good recovery group (P<0.05); However,there was no significant difference between the two groups in terms of age,history of abortion,times of pregnancy,time from operation to the last cesarean section,thickness of adjacent myometrium,WBC and ALB levels (P>0.05). Multivariate logistic regression analysis showed that the number of cesarean sections (OR=1.134,95%CI=1.086~1.184),uterine position (OR=1.845,95%CI=1.264~2.693),diverticulum depth (OR=1.645,95%CI=1.184~2.285) and Hb level (OR=1.421,95%CI=1.117~1.808) were independent influencing factors on the efficacy of hysteroscopic combined with laparoscopic surgery for cesarean scar diverticulum (P<0.05). 【Conclusion】The frequency of cesarean section,uterine position,diverticulum depth and Hb level are the independent influencing factors of hysteroscopy combined with laparoscopy in the treatment of cesarean scar diverticulum,which should be paid attention to clinically. 2022 Vol. 39 (6): 812-814 [Abstract] ( 70 ) HTML (1 KB)  PDF (1160 KB)  ( 97 ) 815 Imaging Features of Gastrointestinal Barium Meal Examination in Adults with Celiac Disease SHI Tian, HUO Zhong, FENG Yan,et al DOI: 10.3969/j.issn.1671-7171.2022.06.005 【Objective】To investigate the imaging features of gastrointestinal barium meal examination in celiac disease (CD) in order to improve the screening level of the disease.【Methods】The clinical data of 20 patients with celiac disease admitted to the people&apos;s Hospital of Xinjiang Uygur Autonomous Region from June 2018 to June 2020 were collected retrospectively. All patients were improved with upper gastrointestinal barium meal or total gastrointestinal barium meal. Two senior radiologists analyzed the performance of digestive tract barium meal in this group. 【Results】 Barium meal imaging examination of the upper gastrointestinal tract showed that 18 (90.0%) of the 20 patients with CD had abnormal duodenal mucosa. The most common manifestation was thickening of duodenal mucosal folds,accounting for 85.0% (17/20). Small niches were seen in most cases,accounting for 60.0% (12/20). The above abnormal manifestations were most obvious in the duodenal bulb and the descending duodenum. In 8 cases,the edge of the descending duodenal mucosa was not smooth,showing "serrated" changes,and in 2 cases,the duodenum was dilated to varying degrees.Twelve of the 20 patients with CD underwent barium meal examination of the whole digestive tract,and 12 patients had abnormal small intestinal mucosa. Among them,9 cases (75.0%) had thickened small intestinal mucosal folds,8 cases (66.7%) had decreased and shallowed jejunal folds,7 cases (58.3%) had uneven intestinal thickness due to different degrees of intestinal dilatation or spasm,and 2 cases (16.7%) had irregular edges of small intestinal mucosa,showing "serrated"changes.【Conclusion】As a non-invasive technique,gastrointestinal barium meal can better show the abnormal manifestations of duodenum and small intestine in CD,and has high clinical value in the screening of CD. 2022 Vol. 39 (6): 815-818 [Abstract] ( 48 ) HTML (1 KB)  PDF (1636 KB)  ( 126 ) 819 Quality Comparison of Three Platelet Preparations and Evaluation of Transfusion Effects in Patients with Hematological Diseases XIONG Zhi-gao, LI Yan-xun, CHENG Jin-feng,et al DOI: 10.3969/j.issn.1671-7171.2022.06.06 【Objective】To compare the quality of mixed concentrated platelets (platelet A),newly improved buffy coat mixed concentrated platelets (platelet B) and apheresis platelets (platelet C) and the effect of clinical infusion in patients with hematological diseases. 【Methods】The laboratory indexes of three platelet preparations were compared,which were divided into preventive infusion and therapeutic infusion according to the purpose of infusion. The platelet count,platelet correction index (CCI) and platelet recovery rate (PPR) before and after infusion were compared to judge the effect of preventive infusion. The blooding fraction before and after infusion was compared to judge the effect of therapeutic infusion,and the adverse transfusion reactions were statistically analyzed. 【Results】The number of platelets in platelet A were lower than that in platelet B and platelet C,the mixed amount of red blood cells (RBC) was higher than that in the other kinds of platelets. There were significant differences in the mixed number of leukocytes (WBC) of three platelet preparations if compared in between (all P<0.05). During preventive infusion,the platelet concentration before infusion in the same group was lower than that 24 hours after infusion,and the difference was statistically significant (all P<0.05). The platelet count 24 hours after infusion in platelet A was lower than that in platelet C,and the difference was statistically significant (P<0.05). There were 131 times of prophylactic infusions,whose infusion ineffective rate was 22.90%. The infusion ineffective rate of ITP patients (primary immune thrombocytopenia) was higher than that of other diseases,and the difference was statistically significant (all P<0.05). During therapeutic infusion,the bleeding fraction before infusion in the same group was higher than that 24 hours after infusion,and the difference was statistically significant (P<0.05). The bleeding fraction 24 hours after infusion in platelet A was significantly higher than that in the other two platelets (P<0.05). The adverse transfusion reaction rate in platelet A was higher than that in platelet C (P<0.05). 【Conclusion】Some laboratory indexes of infusion effect and adverse transfusion reaction rate in platelet C and platelet B were better than those in platelet A. The platelet B could be used as an effective supplement when the supply of apheresis platelets was insufficient. 2022 Vol. 39 (6): 819-822 [Abstract] ( 56 ) HTML (1 KB)  PDF (1115 KB)  ( 40 ) 823 Effects of Tripterygium Wilfordii Polyglycoside on Renal Function and Intestinal Flora in Patients with IgA nephropathy ZHUO Xin, GE Li DOI: 10.3969/j.issn.1671-7171.2022.06.007 【Objective】 To investigate the effect of Tripterygium wilfordii polyglycoside (TWM) on renal function and intestinal flora in patients with IgA nephropathy (IgAN). 【Methods】A total of 170 patients with IgAN were randomly divided into observation group and control group,with 85 cases in each group.

After admission,all patients received routine treatment such as anti infection,expectoration,correction of water and electrolyte. According to the treatment effect,the patients were divided into good prognosis group (significantly effective + effective,n=92) and poor prognosis group (n=72). The basic data of the two groups were compared [gender,age,body mass index (BMI),residential area,smoking history,drinking history,history of immunosuppressant or glucocorticoid use,combined diseases (hypertension,diabetes,chronic obstructive pulmonary disease,hyperlipidemia),mechanical ventilation,RF classification,acute physiology and APACHE Ⅱ score,MODS score] and laboratory indicators (sTREM-1,PCT) difference. The predictive value of age,APACHE Ⅱ score,MODS score,sTREM-1 and PCT level on the prognosis of patients with SP and RF was analyzed by receiver operating characteristic (ROC) curve. The risk factors for poor prognosis of patients with SP and RF were analyzed by multivariate logistic regression.【Results】 Among the 164 patients,56.10% (92/164) had a good prognosis and 43.90% (72/164) had a poor prognosis. There was no significant difference between the two groups in terms of gender,BMI,residential area,drinking history,history of immunosuppressant or glucocorticoid use,hypertension,chronic obstructive pulmonary disease,hyperlipidemia and RF classification (P>0.05); The proportion of patients with smoking history,diabetes and mechanical ventilation in the poor prognosis group was significantly higher than that in the good prognosis group(P>0.05).

According to their disease conditions,they were divided into the newly diagnosed group of 30 cases,the remission group of 32 cases, and the refractory group of 21 cases. A total of 30 bone marrow specimens from patients with normal bone marrow and non-hematopoietic system diseases who were treated in our hospital during the same period,which matched the age and sex of the observation group,were selected as the control group. The relative expressions of miR-17 and ATG12 in BMMNC were detected and the relationship of relative expressions of miR-17 and ATG12 were analyzed . 【Results】The relative expressions of miR-17 and ATG12 in the observation group were higher than those in the control group (P<0.05).The relative expressions of miR-17 and ATG12 in the newly diagnosed group and the refractory relapse group were significantly higher than those in the control group (P<0.05),while the relative expressions of miR-17 and ATG12 in the remission group were significantly lower than those in the newly diagnosed group and the refractory relapse group (P<0.05). The relative expressions levels of miR-17 and ATG12 in the remission group and the control group showed no statistically significant difference (P>0.05),while the relative expressions levels of miR-17 and ATG12 in the refractory and relapsed group showed no statistically significant difference from the newly diagnosed group (P>0.05). The relative expression level of miR-17 in the newly diagnosed patients with WBC ≥ 50×109/L was significantly higher than that in the patients with WBC< 50×109/L (P<0.05),while the relative expression level of ATG12 was significantly lower than that in the patients with WBC< 50×109/L (P< 0.05). The relative expression level of miR-17 and ATG12 in the patients with B-ALL was significantly higher than that in the patients with T-ALL (P<0.05).The relative expression levels of miR-17 and ATG12 were independent of gender,age,chromosome abnormality and prednisone induction sensitivity (P>0.05). Pearson correlation analysis showed that the relative expression levels of miR-17 and ATG12 were positively correlated (r=0.414,P<0.05) 【Conclusion】Both miR-17 and ATG12 are highly expressed and they are positively correlated in BMMNC of adult ALL patients. The autophagy activity of ATG12 was enhanced,suggesting that changes in the expression of miR-17 and ATG12 may be related to the occurrence,development and recurrence of ALL,whose specific mechanism of action remains to be further studied. 2022 Vol. 39 (6): 905-908 [Abstract] ( 39 ) HTML (1 KB)  PDF (1362 KB)  ( 37 ) 909 Serum FIB,TSP-1 Levels in Children with Severe Mycoplasma Pneumonia and their Correlation with Prognosis GAO Shi-yue, CAO Ya-min DOI: 10.3969/j.issn.1671-7171.2022.06.029 【Objective】To investigate the serum levels of human fibrinogen (FIB) and platelet reactive protein-1 (TSP-1) in children with severe Mycoplasma pneumoniae pneumonia (MPP),and to analyze their correlation with prognosis. 【Methods】 A total of 80 children with severe MPP (severe group) and 80 children with mild MPP were selected as the mild group. According to the prognosis of the children,the children with severe MPP were divided into the improvement group (n=53) and the deterioration group (n=27). The levels of FIB and TSP-1 in serum were detected by enzyme-linked immunosorbent assay. The correlation between FIB and TSP-1 levels and pneumonia severity index (PSI) was analyzed by Pearson method. The predictive value of FIB and TSP-1 in serum for the poor prognosis of children with severe MPP was analyzed by ROC curve.【Results】Compared with the mild MPP group,the platelet count (PLT),mean platelet volume (MPV),D-dimer,antithrombin Ⅲ (AT-Ⅲ),white blood cell count (WBC),neutrophil count (NEU),lactate dehydrogenase (LDH),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) and PSI score in the severe MPP group were significantly higher (P<0.05). The levels of serum FIB and TSP-1 in the severe group were significantly higher than those in the mild group (P<0.05). The expression levels of FIB and TSP-1 in serum of children with severe MPP were positively correlated with PSI score (P<0.05). The expression levels of FIB,TSP-1 and PSI score in the MPP group and the deterioration group were significantly higher than those in the mild MPP group (P<0.05). The sensitivity,specificity and area under the curve were 88.89%,81.13% and 0.920 respectively.【Conclusion】The levels of serum FIB and TSP-1 in children with severe MPP are significantly increased,which is related to the severity of the disease,and may be used as a potential marker to predict the poor prognosis of children with severe MPP. 2022 Vol. 39 (6): 909-912 [Abstract] ( 33 ) HTML (1 KB)  PDF (1139 KB)  ( 51 ) 913 Application of High-Dose Oxycodone Sustained-Release Tablets in Moderate and Severe Pain in Patients with Advanced Digestive System Tumors GUO Zheng-she, HE Yin-bin DOI: 10.3969/j.issn.1671-7171.2022.06.030 【Objective】To explore the application effect of high-dose oxycodone sustained-release tablets in moderate and severe pain in patients with advanced digestive system tumors.【Methods】 The clinical data of 60 patients with moderate and severe pain of advanced digestive system tumors treated in the oncology department of Xi&apos;an Fouth Hospital from January 2017 to April 2020 were analyzed retrospectively.

There was no significant difference in age,sex and diabetes among patients with different serum PTX3 and HBP levels (P>0.05);There were significant differences in clinical stages,MELD scores and compl ications (P<0.05). The levels of serum PTX3 and HBP in the death group were significantly higher than those in the survival group (P<0.05). The area under curve (AUC) of serum PTX3 in predicting poor prognosis was 0.876,the sensitivity was 92.1%,and the specificity was 80.0%; The AUC of serum HBP in predicting poor prognosis was 0.893,the sensitivity was 71.1%,and the specificity was 95.0%; The AUC predicted by the two methods was 0.959,the sensitivity was 84.2%,and the specificity was 95.0%. 【Conclusion】 Serum PTX3 and HBP are highly expressed in patients with CLF complicated with bacterial infection. The high expression of PTX3 and HBP is related to the poor prognosis of patients. It is a potential biological index to diagnose the prognosis of patients. 2022 Vol. 39 (6): 921-924 [Abstract] ( 32 ) HTML (1 KB)  PDF (1135 KB)  ( 37 ) 925 Correlation between of Levels of Serum HB-EGF and HIF-1α and its Prognosis in Children with Lupus Nephritis LIU Yan, SUN Cai-xia DOI: 10.3969/j.issn.1671-7171.2022.06.033 【Objective】To investigate the correlation between levels of serum heparin binding epidermal growth factor (HB-EGF) and hypoxia inducible factor-1α (HIF-1α) in children with lupus nephritis and its prognosis.【Methods】 A total of 70 children with lupus nephritis (observation group) admitted to the first Yulin hospital from July 2016 to July 2018 were followed up for 18~36 months. The children were divided into good prognosis group (n=55) and poor prognosis group (n=15) according to whether there were composite renal end points at the end of follow-up. A total of 50 healthy children who underwent physical examination in our hospital at the same time were selected as the control group. Levels of the serum HB-EGF and HIF-1α of subjects in different groups were measured at admission. The subjects&apos;s operating characteristic curve (ROC curve) and the area under curve (AUC) were used to evaluate the predictive value of their expression levels on the prognosis of children with lupus nephritis,and logistic regression analysis was performed on the related factors affecting the prognosis of children with lupus nephritis.【Results】The levels of serum HB-EGF and HIF-1α in the observation group were significantly higher than those in the control group(P<0.05). The levels of serum creatinine,blood urea nitrogen,serum HB-EGF and HIF-1αin the poor prognosis group were significantly higher than those in the group with good prognosis (P<0.05). The expression level of the area under the curve (AUC) of serum HB-EGF and HIF-1α were 0.869 and 0.822 respectively,the cut-off values were 39.692 pg/mL and 97.448 ng/L respectively,the sensitivity were 86.70% and 66.70% respectively,and the specificity were 76.40% and 92.70% respectively; The combined AUC was 0.937,the sensitivity and specificity were 80.00% and 96.40%. Logistic analysis showed that high levels of serum HB-EGF and HIF-1α were independent risk factors influencing the prognosis of children with lupus nephritis.【Conclusion】 The levels of serum HB-EGF and HIF-1α in children with lupus nephritis has increased significantly,and its expression level has a certain predictive value for the prognosis of children with lupus nephritis. 2022 Vol. 39 (6): 925-928 [Abstract] ( 34 ) HTML (1 KB)  PDF (1151 KB)  ( 33 )
