Objective To explore the association between clusterin(CLU) gene rs11136000 poly-morphism and late-onset Alzheimer's disease ( LOAD) in Bai population from Dali Bai Autonomous Prefec-ture of Yunnan Province.Methods A case-control study including 109 LOAD patients and 120 normal con-trols matched for age,sex and level of education was taken in Dali Bai population.Polymerase chain reaction (PCR) and single nucleotide polymorphism (SNP) site testing were used to detect genotype and allele fre-quency of CLU SNP rs11136000.SPSS 17.0 was applied to analyze the data.Result ①The different fre-quency ( C:65.60%,T:34.40%,CC:38.53%,CT:54.13%,TT:7.34%) of CLU SNP rs11136000 genotypes and alleles distribution in Bai between LOAD patients and healthy controls showed no statistical significance (χ2=1.529, P=0.216;χ2=2.805, P=0.246) .②The serum total cholesterol ( TC) of LOAD patients was significantly higher than that in that of control group( t=2.508, P=0.013) .Conclusion The results suggest that CLU rs11136000 polymorphism may not be the susceptible gene of LOAD,and high serum total choles-terol is more common in LOAD patients.

Objective To explore the relationship of chemotherapy sensitivity and expression of multidrug resistance genes and apoptosis regulation genes in human breast cancer cell lines.Methods MTT assay was used to detect the sensitivity to adriamycin(ADM),cisplatinum(DDP),mitomycin C(MMC),fluorouracilum(5-Fu),carmustine(BCNU) in five breast cancer cell lines including Bcap37,MCF-7,T47D,MDA-MB-231and MDA-MB-435.Multidrug resistance genes including P-glycoprotein(P-GP),Glutsthione-s-transferases-?(GST-?),Lung resistance protein(LRP),multidrug resistance related protein(MRP),MGMT and apoptosis regulation genes FAS,BCL-2,P53 and P16 were examined by flow cytometry(FCM).Results The chemotherapy sensitivity was obviously divergent in different breast cancer cell lines.The correlation analysis showed that there were positive correlations between the sensitivity to 5-Fu in breast cancer cell lines and the expression of P16.There was no correlation among the sensitivity to other drugs and expression of other genes.Conclusions The sensitivity to 5-Fu is related to the expression of P16 in breast cancer cell lines.

Objective: To investigate the expression of HSP-27,-60 and -90 in gastric cancer and its clinical significance. Methods:66 cases of gastric carcinoma was detected by immunohistochemistry HSP-27,60 and 90 of the expression and clinical significance of combined with clinical and pathological characteristics, tumor cell proliferation and survival analysis of three kinds of heat shock protein expression. Results: HSP-27,-60 and -90 were highly expressed in gastric cancer tissues. HSP-27 expression and tumor size (pT,P=0. 026),organ metastasis (pM,P=0. 046) and pathological staging (P=0. 041),HSP-27 staining intensity and lymph node status were significantly correlated ( pN, P=0. 042 ) . HSP-60 expression was associated with gender ( P=0. 011),and HSP-60 staining intensity was associated with age (P=0. 027) and tumor grade (P=0. 031). There was no correlation between HSP-90 expression and the clinical pathological parameters of this study; however, the intensity of HSP-90 staining was significantly correlated with tumor size (P=0. 020,pT). Single factor analysis showed that HSP-90 was significantly associated with longer survival (P=0. 033). Multivariate analysis demonstrated that HSP-90 was highly expressed as an independent prognostic factor for gastric cancer (P=0. 026). Conclusion: the HSP-27,-60 and -90 and some clinical pathological parameters. These parameters is very important for the treatment of patients with gastric cancer. The high expression of HSP-90 in patients with gastric cancer were inde-pendent prognostic indicators.

Objective:To investigate the specific effect of minimally invasive hard channel intracranial hematoma crush suction flow on patients with cerebral hemorrhage, and to analyze the prognostic factors.Methods:A total of 80 patients with primary intracerebral hemorrhage who were treated in Bengbu First Peopl′s hospital from Aug. 2014 to Aug. 2018 were selected, with 52 males and 28 females, aged from 48 to 81 years and averaged (66.07±13.34) years. The prognosis of patients was assessed using the Bathel Index (BI), and the patients were divided into a control group (BI≥ 60 point considered a good prognosis, n=54) and an experimental group (BI<60 point considered a poor prognosis, n=26). Suspicious prognostic factors were formulated, including gender, age, average drainage time, average puncture needle indwelling time, average hospital stay, Glasgow score, time from injury to operation, bleeding volume, cause of disease, bleeding site, postoperative rebleeding to carry out univariate analysis between groups, and incorporate the difference items in univariate analysis into multivariate logistics regression analysis to explore related prognostic factors were compared by single factor analysis, and the difference items in the single factor analysis were included into the multivariate logistics regression analysis for the related prognostic factors exploring. Results:The hemorrhages was successfully cleared in all patients, and the average drainage time was (5.07±1.25) days. Mean needle retention time was (4.84 ± 1.37) d. Mean length of stay time was (15.26±1.44) days. Allpatients completed follow-up after operation. During 1 year of follow-up, 12 patients showed obvious brain atrophy, subdural broadening and effusion. All patients were followed up for 3 years, and their symptoms completely disappeared and their daily living ability recovered. No death was occured during the follow-up. According to the BI assessment results, the scores of 54 patients were ≥60, with an average score of (74.57±4.36). The scores of 26 patients were <60, with an average score of (48.24±5.12). The age, time from injury to operation and amount of blood loss of control group were significantly lower than those of experiment group, and Glasgow scores were significantly higher than those of experiment group, with statistically significant differences ( P<0.05). The percentage of patients in control group with infratentorial hemorrhage (14.81%) was significantly lower than that in experiment group (34.62%), and the rate of postoperative re-bleeding (1.85%) was significantly lower than that in experiment group (23.08%), with statistically significant differences ( P<0.05). Glasgow score was positively correlated with the prognosis of patients ( OR=3.449, P=0.005). The time from injury to operation was negatively correlated with the prognosis ( OR=0.580, P=0.023). Supratente hemorrhage was a protective factor for patient prognosis ( OR=3.813, P=0.024). Postoperative re-bleeding was correlated with the patients ( OR=19.963, P=0.008). A ROC curve was drawn with Glasgow score and the time from injury to operation. Glasgow score was selected as cut-off point at 7.5 point, with sensitivity of 96.30% and specificity of 88.46%. The time from injury to operation was selected as the cut-off point at 8.35 h, with sensitivity of 84.62% and specificity of 92.59%. Conclusion:Minimally invasive hard channel crush suction flow is effective and safe in the treatment of intracranial hematoma. The severity of cerebral hemorrhage, infratentorial hemorrhage and postoperative re-bleeding are prognostic factors.

Objective:To investigate factors associated with acute kidney injury(AKI) in postoperative colorectal cancer patients.Methods:The clinical data of 376 colorectal carcinoma (CRC) patients at Department of General Surgery, Affiliated Cancer Hospital of Zhengzhou University from Jan 2018 to Jun 2021 were retrospectively analyzed. Patients were divided into acute kidney injury (AKI) ( n=29) and non-AKI groups ( n=347). The demographic information, perioperative status, laboratory results and other relevant data of the two groups were compared . Binary logistic regression was used to analyze the independent risk factors for postoperative AKI. Results:Twenty-nine CRC patients (7.7%) had postoperative AKI. Binary Logistic regression analysis showed that preoperative hypertension ( OR=3.487, 95% CI: 1.081-11.251, P=0.037), anemia ( OR=3.158, 95% CI: 1.114-8.953, P=0.031), inadequate intraoperative crystalloid infusion ( OR=0.998, 95% CI: 0.997-0.999, P=0.007), low intraoperative mean arterial pressure ( OR=0.915, 95% CI: 0.863-0.970, P=0.003) and moderate to severe postoperative decline in hemoglobin levels ( OR=4.105, 95% CI: 1.487-11.335, P=0.006) were independent risk factors. Conclusion:Preoperative hypertension, anemia, inadequate intraoperative crystalloid infusion, low intraoperative mean arterial pressure, and moderate to severe postoperative decline in hemoglobin levels were independent risk factors for AKI development in colorectal cancer patients.

【Objective】 To explore the quantitative value of key points for ABO blood group initial screening in fixed blood donation sites, so as to provide reference for standardized testing process of sliding method. 【Methods】 Several groups of experiments were carried out to illustrate the optimal conditions, including the serum dosage of monoclonal reagent, red blood cell dosage of blood sample, and reaction time in ABO blood group initial screening, by sliding method, and the quantitative value of key points of sliding method was preliminarily determined. Blood typing tests of 310 blood donor samples including type A, B, O, AB, subtype A and subtype AB were conducted to evaluate the effects of quantitative value of key points in the initial screening procedure. The test tube method would be conducted if the results are inconsistent with the fully automated blood grouping analyzer. The ABO subtypes suspected are identified by serological and molecular biological methods. 【Results】 The quantitative value of key points in initial screening procedure of sliding methods was as follows: 2 drops of reagent serum, 5-10 μL of whole blood and 3 minutes of reaction time. The concordance rate of ABO blood type screening comparison experiment in 310 blood donors was 100%. 【Conclusion】 ABO blood group initial screening by sliding method with quantitative value can effectively standardize the pre-donation blood type screening in fixed blood donation sites, and can meet the requirements of ABO blood group initial screening.

To analyze statistically the situation of the National Natural Science Foundation of China (NSFC) from 2007 to 2016 in the field of acupuncture and moxibustion for supporting the national Universities colleges of traditional Chinese medicine on the General Program (GP) and the National Science Fund for Young Scholars (NSFYS). In view of five aspects, named fund, supporting units, key words, method, disorder and signal path, the differences were compared between GP and NSFYS, the following characteristics were summarized. ① The fund aid was increased from 2007 through 2013 and down-regulated from 2013 through 2016. In recent ten years, the funding condition was fluctuated, but increasing in tendency generally. ② The relevant projects of the same research direction had been approved continuously for over 3 years in a part of TCM universities, in which, the research continuity was the hot topic. ③ Regarding the therapeutic methods, acupuncture was the chief therapy; electroacupuncture, moxibustion and acupoints were involved as well. ④ The disorders involved in the research were cerebral ischemia, myocardial ischemia and reperfusion injury. It is suggested that the ischemic disorder is predominated in the research. ⑤ The signal path occupied the main research index system, including cell proliferation, metabolism, immune, apoptosis and autophagy. The researches on the other aspects were less.

OBJECTIVETo evaluate the safety and efficacy of the perineal rectosigmoidectomy (Altemeier procedure) in the treatment of full thickness rectal prolapse.

METHODSClinical and follow-up data of 52 patients with full thickness rectal prolapse undergoing Altemeier procedure in 9 hospitals from September 2010 to July 2016 were analyzed retrospectively. Of which 38 cases were from Zhongnan Hospital of Wuhan University, 1 case from Suizhou Central Hospital of Hubei province, 1 case from Jingzhou Second People's Hospital of Hubei province, 3 cases from Wuxue First People's Hospital of Hubei province, 1 case from Jingmen First People's Hospital of Hubei province, 1 case from Tuanfeng County Hospital of Hubei province, 4 cases from Jingzhou Central Hospital of Hubei province, 2 from PLA Rocket Army General Hospital, 1 case from the Affiliated Hospital of Xuzhou Medical University in Jiangsu province. Altemeier operation steps: The line shaped teeth, the prolapsed rectum is first exposed to the anus. In the dentate line proximal 1-3 cm with ultrasonic knife or Ligasure ring outer rectal incision, using electric knife to mark pre resection line in rectal mucosa. Open down in front of the pelvic peritoneum. Incision of the outer intestine and the reduction of the internal rectum and part of sigmoid colon. To free and remove excess pelvic retroperitoneal, pelvic peritoneum and be at the top of the colon or rectum anterior pelvic reconstruction suture. The rear of the levator ani muscle forming rectum. Pull gently to the anus and rectum and sigmoid, in the absence of tension, 2-3 cm outside the anus was selected as the proximal inner bowel pre resection line, along the line of pre transection of proximal bowel resection, again the broken end of intestine full-thickness end-to-end anastomosis. Postoperative complication and recurrence were summarized. Gastrointestinal quality of life index (GIQLI), Wexner constipation score and Wexner fecal incontinence score were used to evaluate the efficacy.

RESULTSAll the 52 patients were beyond moderate full thickness rectal prolapse. Thirty-one were male and 21 were female with age ranging from 22 to 83 (average 53) years. The length of prolapsed rectum was 6 to 20 (average 9) cm and course of disease was 0.5 to 46(average 19.5) years. No perioperative death. Five patients (9.6%) had postoperative complications, including 2 anastomotic bleeding, 1 wall portion dehiscence of anastomosis, 1 anastomotic stenosis, and 1 malnutrition. Recurrence rate was 9.6%(5/52) within the long-term follow-up of 5 to 71 (median 40) years. Compared with the preoperative results, Wexner constipation score and Wexner fecal incontinence score decreased obviously (2.1±1.4 vs. 4.6±3.4, 4.8±4.1 vs. 6.8±4.1), and GIQLI significantly increased from 99.6±8.0 to 103.0±9.1 (all P<0.05) at 6-month after operation. Above 3 scores were sustained and continuously improved at 12-, 24-, and 36-month during the follow-up (all P<0.05).

CONCLUSIONAltemeier procedure possesses good efficacy with low morbidity of complication and recurrence in the treatment of full thickness rectal prolapse.
