Objective To examine the relationship between the expressions of mismatch repair proteins,MutS homolog 2(MSH2)and MutS homolog 6(MSH6),and villin and the pathological features in patients with colon cancer.Methods A total of 310 cases of colon cancer patients who were treated at our hospital between January 2017 and September 2021 were selected.The diagnosis of colon cancer of all patients was verified by pathological evaluation.Immunohistochemistry was used to determine the protein expressions of MSH2,MSH6,and villin.The correlation between the expressions of MSH2,MSH6,and villin and the clinicopathological parameters in patients with colon cancer was analyzed accordingly.Multivariate logistic regression was used to analyze the correlation between the expressions of MSH2,MSH6,and villin and the clinicopathological parameters of colon cancer.Kaplan-Meier survival curve was used to compare the 2-year survival rates of colon cancer patients with different expression levels of the proteins.Results Among the 310 patients with colon cancer,the negative expression rates of MSH2,MSH6,and villin proteins in cancer tissues were 8.71％(27/310),9.35％(29/310),and 46.13％(143/310),respectively.The negative expression rates of the three proteins in tissues adjacent to cancer were 3.23％(10/310),4.19％(13/310),and 9.68％(30/310),respectively.The negative expression rates of the three proteins in cancer tissues were all higher than those in adjacent tissues(P＜0.05).Regression analysis showed that the expression of MSH2 and MSH6 in cancer tissues was correlated with the age,the location of tumor lesions,tumor differentiation degree,and lymph node metastasis in colon cancer patients(P＜0.05).The expression of villin in the cancer tissue is correlated with the depth of tumor infiltration,lymph node metastasis,distant metastasis,and clinical staging status in colon cancer patients(P＜0.05).The 2-year survival rates of patients with negative expressions of MSH2 and MSH6 were 51.85％and 44.83％,respectively,which were lower than those of patients with positive expression of MSH2 and MSH6(79.51％and 80.43％,P＜0.05).Thirteen patients(4.1％)had negative expression of MSH2,MSH6,and villin(referred to as"triple negative expressions")in the cancer tissues,and their 2-year survival rate was 30.77％,which was lower than that of colon cancer patients who did not meet the criteria for triple negative expressions(79.12％[235/297],P＜0.05).Conclusion The expressions of MSH2,MSH6,and villin are closely correlated with the pathological features of colon cancer patients.Evaluating the expression of the three proteins may assist in the clinical diagnosis,treatment,and prognosis evaluation of colon cancer.

Objective: To explore the clinical features, the serotype distribution and drug resistance of the isolates in patient with invasive pneumococcal disease (IPD). Methods: By retrieving the laboratory information system in 18 children′s hospitals from 2012 to 2017, the children with IPD were enrolled. Streptococcus pneumoniae (Spn) must be isolated from the sterile sites (blood, cerebrospinal fluid, hydrothorax and joint effusion etc.). The clinical characteristics, serotype, drug resistance, treatment and prognosis were reviewed and analyzed. According to the telephone follow up results, the patients were divided into death group and recovered group. The index as an independent risk factor of mortality was demonstrated by multivariate logistic regression analysis. Results: There were 1 138 children with IPD, including 684 male and 454 female. The proportion of male to female was 1.5∶1. The age ranged from one day to 16 years. The median age was 1 year 3 month. The majority was under 5 years of age (89.3%, n= 1 016), especially under 2 years of age (61.9%, n=704). In all cases, 88.2% (n=1 004) were community acquired infection. The infections included meningitis (n=446, 39.2%), pneumonia with bacteremia (n=339, 29.8%), and bacteremia without focus (n=232, 20.4%). Underlying diseases were found in 242 cases (21.3%). Co-infections were determined in 62 cases (5.4%) with mycoplasma, 27 cases (2.4%) with adenovirus and 34 cases with influenza virus (3.0%). The penicillin insensitivity (PNSP) rates in meningitis and non-meningitis isolates were 69.5% (276/397) and 35.9% (221/615), respectively. There were 81 strains serotyped, in which 93.8% (76/81) were covered by 13-valent protein-polysaccharide conjugate vaccine (PCV13). In the 965 patients who were followed up by phone call, 156 cases (16.2%) were confirmed dead. The independent risk factors for the death were under 2 years of age (OR=2.143, 95%CI 1.284-3.577, P=0.004), meningitis (OR=3.066, 95%CI 1.852-5.074, P<0.01), underlying disease (OR=4.801, 95%CI 2.953-7.804, P<0.01), septic shock(OR=3.542, 95%CI 1.829-6.859, P<0.01), disseminated intravascular coagulation (DIC) (OR=4.150, 95%CI 1.468-11.733, P=0.007), multiple organ failure (OR=12.693, 95%CI 6.623-24.325, P<0.01) and complications of central nervous system (OR=1.975, 95%CI 1.144-3.410, P=0.015). Conclusions Most children with IPD were under 5 years of age, having underlying diseases and acquired the infection in community. The independent risk factors for death were under two years old, meningitis, underlying diseases and multiple organ failure. The problem of drug resistance was severe. The universal immunization of PCV13 would be effective to prevent IPD in Chinese children.

Objective To estimate the diagnostic value of dual-energy CT in gouty arthritis.Methods English and Chinese litera-tures publicated before May 2014 were searched in PubMed,Embase,Cochrane and Wanfang database.Available literatures were selected according to the inclusion and exclusion criterias.Sensitivity,specificity with 95% confidence interval (95% CI)was pooled with bivariate random-effects model.Hierarchical weighted symmetric summary receiver-operating curve (HSROC)was also used in estimating.Meta-regression and sensitivity analysis were used to explore the potential sources of heterogeneity.Results Nine studies were included in the analysis.The pooled sensitivity,specificity and 95% CI were 92%(84-96%)and 88%(83-92%)respectively, area under the HSROC curve was 0.91 (0.88-0.93).There was substantial heterogeneity between studies(I 2 =85%).Conclusion Dual-energy CT is accuracy in diagnosing gouty arthritis.The sources of heterogeneity was not been explored.

Objective To investigate clinical effect of reattribution-cognitive-pharmacy model (RCPM) in the treatment for irritable bowel syndrome(IBS). Methods 125 subjects with diarrhea predominant irritable bowel syndrome (IBS-D) were divided into two groups randomly. 62 patients in group A were treated with 10 ～ 20 mg of paroxetine without any other medication or psychological interview and 63 patients in group B received RCPM with interviewing once a week for 6 sessions and took 10 ～ 20 mg of paroxetine in the same way as group A after a week. The effect was evaluated at the end of 4 weeks and 12 weeks by a questionnaire. Results At the end of 4 weeks,29 patients in group A reported a reduction in abdominal pain,and 28 reported a reduction in stool frequency ,and 12 patients stopped taking paroxetine because of worrying about those side effect . In group B 48 reported a reduction in abdominal pain ,and 42 reported a reduction in stool frequency ,and 3 patients stopped taking paroxetine. At the end of 12 weeks,36 patients in group A reported a reduction in abdominal pain ,and 30 reported a reduction in stool frequency,and 14 patients stopped taking paroxetine because of worry about those side effect. In group B,54 cases reported a reduction in abdominal pain,and 45 reported a reduction in stool frequency,and 5 patients stopped taking paroxetine because of no obvious improvement. Conclusion RCPM can alleviate the abdominal pain and bowl movement frequency of IBS-D,and it seems better than paroxetine treatment alone. RCPM can improve compliance of paroxetine in patients with IBS-D.

Objective To evaluate the effect of hyperuricemia on vascular complications of type 2 diabetes and analysis of the possible mechanism. Methods 586 cases with T2DM were divided into two groups: normal serum uric acid (n=397) and hyperuricemia (n=189).The morbidity of macrovascular and microvascular complications and the serum levels of CRP,TNF,IL-1,IL-2,IL-6,IL-8 and PAI-1 were detected. Results (1)Hyperuricemia group showed higher BMI, blood pressure, TG,TC,LDL,WHR ratio and lower serum HDL-C than the group with normal uric acid (all P<0.05).(2)Group with hyperuricemia showed higher morbidities of macrovascular and microvascular complications than the group with normal uric acid (all P<0.05).(3) Group with hyperuricemia had higher levels of CRP,TNF,IL-6,IL-8,PAI-1 (all P<0.05). Conclusions (1) Hyperuricemia is associated with obesity and dyslipidemia.(2) Hyperuricemia may cause atherosclerosis by inflammation of vascular endothelium, resulting macrovascular and microvascular complications.
