Objective To observe the effects of therapy of supplementing spleen to strengthen lung on patients with adenomatous colonic polyps (ACP) after endoscopic removal . Methods One hundred ACP patients with spleen deficiency and dampness blended with blood stasis were randomly divided into 2 groups after endoscopic removal, 50 cases in the treatment group and 50 cases in the control group. Both groups were treated with diet and behavioral therapy, and the treatment group was simultaneously given oral use of modified Shen Ling Baizhu Powder plus self-moxibustion of bilateral acupoint Zusanli point. After treatment for 6 months and 1.5 years, all of the patients were asked to do the examination of colonoscopy, body mass, body mass index (BMI), and triglyceride (TG). Results (1) After treatment, the mean overall symptom scores of the two groups were improved (P < 0.01 compared with those before treatment) , and the improvement of the treatment group was superior to that of the control group(P < 0.01).(2) After treatment for 6 months and 1.5 years, the recurrence rate of ACP in the treatment group was lower than that in the control group(P < 0.05).(3) After treatment for 6 months and 1.5 years, the body mass, BMI and TG of the treatment group were significantly different from those before treatment(P<0.05), while the control group showed no significant changes(P > 0.05). The effect of the treatment group on improving body mass, BMI and TG was better than that of the control group (P < 0.05). Conclusion The therapy of supplementing spleen to strengthen lung is effective on relieving symptoms of ACP patients, and also has an effect on decreasing BMI and TG as well as the recurrence of ACP after endoscopic removal.

Objective To compare cellular immune responses in mice elicited by Chinese different AIDS candidate vaccines.Methods According to their different immunization procedures,BALB/c mice were immunized with 6 AIDS candidate vaccines,separately.Spleen cells were isolated for the detection of cellular immune response to HIV-specific peptides using enzyme-linked immunosorbent spot(ELISPOT)assay and intracellular cytokine staining(ICS)method.Results AIDS vaccines were evaluated by using potential T-cell epitopes(PTE)Gag,Env and Pol peptides pool and ELISPOT.The positive conversion rates for cellular immune response of 1#-6# vaccines fluctuated from 70% to 100%.The vaccine-induced cellular immune responses to specific peptides pool are different not only in magnitude but also in breadth.The Th1type cytokines,IFN-γand IL-2,were detected with ELISPOT in 1# and 2# vaccines.The productions of IFN-γand IL-2 induced by both of the two vaccines showed a moderate correlation(r1 =0.62,P1 ＜0.01 ;r2=0.79,P2 ＜ 0.01).The positive conversion rate of IFN-γ secreting cells of 1 # vaccine was 66.7%(10/15)mice detected with both ELISPOT and ICS.And the results tested by ELISPOT and ICS showed moderate correlation(r = 0.55,P ＜ 0.05).Conclusion The magnitude and breadth of cellular immune responses induced by different AIDS candidate vaccines are different.Being induced by different AIDS candidate vaccines,the IFN-γand other Th1 type cytokines detected by ELISPOT or ICS could be used to evaluate the cellular immune responses in mice.

Objective To investigate the association between nutrition and peripheral artery disease (PAD) in continuous ambulatory peritoneal dialysis (CAPD) patients.Methods One hundred and two stable CAPD patients from a single center were enrolled in this cross-sectional study.Automatic ankle-brachial index (ABI) measuring system was applied to examine ABI.Patients were divided into PAD group (ABI ＜ 0.9) and non-PAD group (ABI≥0.9).Clinical data were collected.Biochemical parameters were detected.Nutritional status was evaluated by serum albumin,handgrip strength (HGS) and subjective global assessment (SGA).Logistic regression analysis was performed to estimate the association of PAD with each nutritional marker as well as other potential risk factors.Results The incidence of PAD was 23.53％ (24/102).ABI was significantly lower in patients with malnutrition as compared to those without malnutrition [(0.72 ± 0.21) vs (1.04 ± 0.14),P＜0.01].Compared with non-PAD patients,serum albumin (P ＜ 0.01),HGS (P ＜ 0.01),diastolic blood pressure (P ＜ 0.05),serum creatine (P ＜ 0.05)、blood urine nitrogen (P ＜ 0.01) were significantly decreased,but age (P ＜ 0.01),the incidence of malnutrition [SGA,P ＜ 0.01],diabetic status (P ＜ 0.01),cardiovascular disease history (P ＜ 0.01) were significantly increased in PAD patients.Logistic regression analysis showed that serum albumin (OR=0.762,95％ CI:0.611-0.948,P=0.015),HGS (OR=0.988,95％ CI:0.979-0.997,P=0.013) were independent protective factors for PAD,malnutrition [(SGA),OR=21.101,95％ CI:5.008-88.901,P＜0.01] was independent risk factor for PAD in CAPD patients.Conclusions The PAD incidence of CAPD patients in our center is 23.53％.Nutrition is independent factor associated with PAD in CAPD patients.

Objective To investigate AXIN2 mRNA expression level in hepatocellular carcinoma (HCC) , and to analyze the effect of AXIN2 gene methylation status on its mRNA expression and HCC genesis and development. Methods Fifty-three surgical excised HCC specimens and paired adjacent non-cancerous specimens, seven normal liver specimens and five HCC cell lines were collected. The expression of AXIN2 at mRNA level and the methylation status of AXIN2 gene promoter were determined by quantitative PCR. Results The expression of AXIN2 mRNA was lower in HCC tissues (0.1629 + 0.0679) than that in adjacent non-cancerous tissues (0. 4155 + 0. 2330), and there was significant difference (Z= -2. 567, P = 0. 010). The methylation level of AXIN2 gene in HCC and adjacent non-cancerous tissues (39. 77% ±3. 89%, and 36. 92% ±2. 81%) was significantly higher than that in normal liver tissues (7. 38% ±2. 40% , t=-3. 663 ,P = 0. 009;t= -4. 591 ,P = 0. 007).AXIN2 gene was hypermethylated in all five HCC cell lines. There was a negative correlation between AXIN2 mRNA expression level and the degree of methylation ( r = -0. 458, P = 0. 032). The methylation level was higher in TNM Ⅲ patients of HCC than that in TNM Ⅰ and Ⅱ patients (P =0.008). Conclusion The down-regulation of AXIN2 gene mRNA expression is correlated with its hypermethylation status. The low expression of AXIN2 mRNA and the abnormal methylation of promoter may be one of the important mechanism of HCC genesis and development.

Objective:To analyze the influencing factors of death in patients with acute respiratory distress syndrome (ARDS) combined with acute kidney injury (AKI) in intensive care unit (ICU) after continuous renal replacement therapy (CRRT).Methods:The demographic and clinical data of ICU patients with ARDS combined with AKI after CRRT at Henan Provincial People's Hospital from January 1, 2018 to December 31, 2018 were collected. According to the final treatment results of this hospitalization, the patients were divided into death group and survival group. Survival was defined as the improved patient's condition and hospital discharge. Death was defined as the patient's death during the ICU hospitalization or confirmed death after abandoning treatment and automatically being discharged from the hospital in the follow-up. The basic clinical characteristics and CRRT status between the two groups were compared. Multivariate logistic regression method was used to analyze the influencing factors of death in patients.Results:A total of 132 patients were enrolled, of which 90 patients (68.2%) died, with 84 males (63.6%) and median age of 59(45, 73) years. Compared with the survival group, the death group had higher age, proportion of malignant tumors, sequential organ failure assessment (SOFA) score, number of organ dysfunction and proportion of positive balance of fluid accumulation at 72 hours, longer time from entering ICU to CRRT, and lower mean arterial pressure (minimum value) and oxygenation index (all P<0.05). Multivariate logistic regression analysis results showed that the age≥60 years old ( OR=4.382, 95% CI 1.543-12.440, P=0.006), large number of organ dysfunction ( OR=1.863, 95% CI 1.109-3.130, P=0.019), high SOFA score ( OR=1.231, 95% CI 1.067-1.420, P=0.004) and long time from ICU admission to CRRT ( OR=1.224, 95% CI 1.033~1.451, P=0.020) were independent influencing factors of death in patients with ARDS combined with AKI after CRRT, and high oxygenation index ( OR=0.992, 95% CI 0.986-0.998, P=0.010) was an independent protective factor for patients' prognosis. Conclusions:The mortality of patients with ARDS combined with AKI after CRRT is still high. The age≥60 years old, large number of organ dysfunction, high SOFA score and long time from ICU admission to CRRT are independent influencing factors for death, and high oxygenation index is an independent protective factor for prognosis in patients with ARDS combined with AKI after CRRT.

Objective:To investigate the incidence of acute kidney injury (AKI) following pancreaticoduodenectomy and related risk factors in elderly patients.Methods:The clinical data of elderly patients who underwent pancreaticoduodenectomy in Henan Provincial People′s Hospital from January 2017 to June 2020 were collected retrospectively. According to the changes of serum creatinine within 48 h or 7 days after operation, the patients were divided into AKI group and non-AKI group. The basic clinical characteristics of the two groups were compared, and the incidence of AKI was calculated. Multivariate logistic regression model was used to analyze the risk factors of postoperative AKI.Results:A total of 322 elderly patients were enrolled, with age of (67.1±5.2) years old (60-85 years old) and 186 males (57.76%). Among 322 elderly patients, there were 41 patients (12.73%) suffering from AKI following pancreaticoduodenectomy. Compared with the non-AKI group, the level of bilirubin in AKI group was higher ( Z=-2.012, P=0.044), and the level of hemoglobin in AKI group was lower ( Z=-2.111, P=0.035). Multivariate logistic regression analysis showed that increased preoperative total bilirubin ( OR=1.003, 95% CI 1.000-1.006, P=0.027) and postoperative exploratory laparotomy ( OR=3.936, 95% CI 1.071-14.460, P=0.039) were the independent influencing factors for AKI after pancreaticoduodenectomy in elderly patients. Conclusions:The incidence of AKI after pancreaticoduodenectomy in elderly patients is 12.73%. Preoperative high bilirubin and postoperative exploratory laparotomy may be the independent risk factors for AKI after pancreaticoduodenectomy in elderly patients.

Objective To analyze the screening results of tumor markers carbohydrate antigen 724 (CA-724), carbohydrate antigen 153 (CA-153), carbohydrate antigen 125 (CA-125), carbohydrate antigen 199 (CA-199) and carcinoembryonic antigen (CEA) in the 45 ~ 60-year-old health examination population in Chengdu area. Methods A total of 2 268 healthy people aged 45 ~ 60 years old living in Chengdu area from May 2019 to August 2020 were selected. Levels of serum tumor markers CA-724, CA-153, CA-125, CA-199 and CEA were detected by electrochemiluminescence. Positive rates of different tumor markers and confirmed diagnosis of malignant tumors were statistically analyzed. People with positive and negative tumor markers were respectively included in the positive group and the negative group, and their serum tumor markers were compared. The screening results of tumor markers in the health examination population of different gender and age, and the diagnostic efficiency of each tumor marker for malignant tumors were analyzed. Results Among the 2 268 healthy people, the positive rates of CA-724, CA-153, CA-125, CA-199 and CEA were 10.05%, 4.98%, 1.10%, 7.01% and 4.76%, respectively. A total of 72 cases were positive for tumor marker detection, with a total positive rate of 3.17% (72/2,268). Among them, 12 cases were diagnosed as early or mid-term tumors by pathology, imaging and other examinations, with a total tumor detection rate of 0.53% (12/2,268), including 8 cases of malignant tumors, with a detection rate of 0.35% (8/2,268). The levels of CA-724, CA-153, CA-125, CA-199 and CEA in the tumor markers positive group were higher than those in the negative group (P<0.05). The CA-125 and CA-199 positive rates in males were lower than those in females, while CEA positive rate was higher in males than in females (P<0.05). Positive rates of CA-153, CA-199 and CEA in different age groups showed statistically significant differences (P<0.05). Positive expression of CA-153 and CA-199 mainly occurred in the 51~60 years old group, and positive expression of CEA mainly occurred in the 45~50 years old group. ROC curve analysis showed that combined detection of CA-724, CA-153, CA-125, CA-199 and CEA had the highest sensitivity, specificity and accuracy in predicting malignant tumors, and the area under the curve was the largest (0.865). Conclusion Tumor markers CA-724, CA-153, CA-125, CA-199 and CEA are highly expressed in the 45 ~ 60-year-old health examination population in Chengdu area, and positive rate of CA-724 is the highest. Levels of tumor markers in people of different gender and age are also different. Joint detection of various tumor markers is conducive to early detection and treatment of the disease, and reduction of deterioration risk.
