Objective To clarify great benefit to prevention of wound infection as well as reduction of economic expenditures by a new method of connecting latex gloves and cigarettes in peritoneal drainage. Methods We randomly selected 121 cases of patients with peritoneal pyogenic infection, divided them into the latex gloves group (64 eases)and the common dressing group (57 cases). The incision infection rate and eco-nomic cost in two groups were comparately studied. Results The latex gloves group's incision infection rate was 10.94% (7 / 64), the common dressing was 31.58% (18/57). Each patient of the latex gloves group spent less cost about 15.70 yuan,changed dressing 5.3 times less than the common dressing group. Conclusions Connecting latex gloves and cigarettes in peritoneal drainage is a new method of reducing economic expandi-tures and the chances of incision infection. Clinical application of this method should be fully prospected.

Objective To investigate the expressions of apoptosis stimulating protein of P53 (ASPP)family in colorectal carcinoma tissue and to explore their relationship with the clinicopathological characteristics of colorectal carcinoma,and to clarify the effect of ASPP family in the development of colorectal carcinoma.Methods 45 cases of colorectal carcinoma tissue and 20 cases of healthy controls were selected. Among 45 cases of colorectal carcinoma tissue, there were 1 1 cases of well differentiated colorectal carcinoma, 2 1 cases of moderately differentiated colorectal carcinoma,and 13 cases of poorly differentiated colorectal carcinoma;7 cases of T1 stage colorectal carcinoma,8 cases of T2 stage colorectal carcinoma,25 cases of T3 stage colorectal carcinoma,and 5 cases of T4 stage colorectal carcinoma;19 cases of N1 stage with lymph node metastasis,26 cases of N0 stage without lymph node metatasis.The expressions of ASPP1,ASPP2,and iASPP in 45 cases of colorectal carcinoma tissue and 20 cases of normal colon tissue were detected by immunohitochemistry SP method,and the correlations between the expressions of ASPP family and the pathologic typing,infiltrative depth,and lymph node metastasis of colorectal carcinoma were analyzed. Results ①The immunohitochemical staining results showed that the ASPP family members expressed in colorectal carcinoma tissue and normal colon tissue, and there were no significant differences in ASPP1 and ASPP2 positive rates between colorectal carcinoma tissue and normal colon tissue (P>0.05);the positive expression rate of iASPP in colon cancer tissue was higher than that in normal colon tissue (P<0.01).② The expression of ASPP1 in colon caner tissue had no correlation with the differentiation degree of tumor cells (rs=0.163,P>0.05);the expression of ASPP2 positive rate was decreased when the differentiation degree of tumor cells reduced,they had positive correlation (rs=0.454,P=0.002);the expression of iASPP in colon cancer tissue had no correlation with the differentiation degree of tumor cells (rs=-0.171,P>0.05).③ The expression of ASPP1 in colon caner tissue had no correlation with the infiltrative depth of tumor (rs=-0.268,P>0.05);the expression of ASPP2 positive rate was decreased when the tumor infiltrative depth increased,they had negative correlation (rs=-0.348,P<0.05);the expression of iASPP in colonic carcinoma caner tissue had no correlation with the infiltrative depth of tumor (rs=0.231,P>0.05).④The expressions of ASPP1,ASPP2, and iASPP in colon caner tissue had no correlation with lymph node metastasis (rs=0.089,rs=0.044,rs=0.210, P>0.05).Conclusion The expression levels of iASPP in colon cancer and normal colon tissues are different,it may be useful for the diagnosis, differential diagnosis and evaluation in benign and malignant colorectal diseases. The expression of iASPP is negatively correlated with the pathologic typing and neoplasm staging of colorectal carcinoma,it indicates that iASPP can be used as a indicator in judging the prognosis of colorectal carcinoma.

Objective To examine the pathological changes in the liver of an AIDS patient with complicated infection of Pneumocystis carinii(PC). \ Methods\ A liver biopsy was made. The tissue was stained with HE, PAS, Giemsa, GMS, and acid\|fast staining, and examined under light microscope and transmission electron microscope. \ Results\ Granulomas (acid\|fast negative) in the tissue and numerous pathogens (PAS positive) in hepatic sinusoids were detected. Giemsa and GMS staining and electron microscopy all confirmed that the pathogen was Pneumocystis carinii. \ Conclusion\ The pathological findings revealed a diffuse extrapulmonary infection of Pneumocystis carinii in the patient of AIDS.

ObjectiveTo explore the biological features of colorectal adenoma with chicken-skin mucosa ( CSM ) and its clinical significance.MethodsExpression of cell proliferation markers ( Ki-67 and COX-2) and apoptosis-related factors ( survivin and caspase-3) in normal colorectal mucosa,colorectal adenoma without CSM,colorectal adenoma with CSM and colorectal adenocarcinoma were detected by immunohistochemistry SP method and enzyme-linked immunosorbent assay (ELISA).ResultsImmunohistochemical results revealed a decreased trend in expressions of Ki-67 and COX-2 from colorectal adenocarcinoma through colorectal adenoma with and without CSM to normal colorectal mucosa,while the expressions of survivin and caspase-3 showed an increased trend.By ELISA,the expressions of Ki-67,COX-2,surviving and caspase-3 showed no significant difference (P > 0.05 ) between colorectal adenoma with CSM and coloreetal adenocarcima,while these variables were significantly different (P < 0.05) between coloreetal adenoma with and without CSM,so as well between normal colorectal mucosa and other 3 groups.ConclusionThe biological characteristics of colorectal adenoma with CSM are different from those without,showing an activated cell proliferation and inhibited cell apoptosis with increased carcinogenesis risk.

We analyzed the pathogenic characteristics of Salmonella strains isolated from diarrhea patients in Wuxi City,Jiangsu Province,China and compared the differences among pulse field gel electrophoresis (PFGE) patterns of main serotype strains,so as to provid scientific basis for disease control.After biochemical identification of the Salmonella strains isolated from infectious diarrhea patients in Wuxi in 2015,drug susceptibility test,serotyping and PFGE were applied to analyze these strains.Results showed that a total of 32 Salmonella strains were detected from 756 diarrhea specimens with a positive rate of 4.23 %.The infection occurred more frequently between May and October and adults aged more than 60 years old affected mostly.There was no significant difference between genders in infected population.The drug susceptibility test indicated that the antibiotic resistance rate of these Salmonella strains to ampicillin (56.25 %) was the highest,and to ciprofloxacin(6.25 %)and Ceftazidime (6.25%) were the lowest.The 32 Salmonella strains belonged to 11 serotypes,and S.enteritidis(31.25%)and S.typhimurium(21.88%) were the predominant serotypes.PFGE showed that the pattern similarity of all S.enteritidis was more than 85 %;PFGE patterns of S.typhimurium were different.In conclusion,the infection of Salmonella from diarrhea patients in Wuxi City had obvious season and age specific distribution,and the most prevalent serotype of Salmonella was the S.enteritidis.It is necessary to strengthen the surveillance of Salmonella concurrently in food and environment.

Objective To establish a human ovarian carcinoma cell line with directional highly lymphatic metastasis and to study their biological characteristics.Methods The clone cells of ovarian carcinoma,SKOV3,were inoculated into the hind foot pad of nude mice.The cancer cells of lymph node metastatic foci were transplanted into nude mice again when the metastatic nude of mice were observed.After repetition of this procedure for 3 cycles,the metastatic rate and the metastatic paths were observed in nude mice of every passage.We used limited dilution method to separate and select colonial cells with directional highly lymphatic metastatic potentials from the lymphatic metastasis of human ovarian carcinoma cell line SKOV3.The ceils with biological characteristics were assayed by growth curve,HE staining,karyotype analysis,nude mice transplantation and immunohistochemistry,respectively.Results We established a series of cell lines from lymph node metastasis and designated them as SKOV3-PM1,SKOV3-PM2 and SKOV3-PM3 cell strain.When the cells of SKOV3-PM3 were injected into the hind foot pad of nude mice, they produced 100%(10/10)spontaneous lymphatic metastasis.The lymphatic metastatic rates(26/10) were stable and higher than the mother cell line(1/10,P
