Objective To explore the principles and methods of surgcal treatment for acute neoplastic colorectal obstruction.Methods The clinical data of 103 patients diagnosed as acute neoplastic colorectal obstruction were analyzed retrospectively.Results In this group,80 cases underwent emergency surgical treatment,(among) which,25 cases of carcinoma of right colon underwent primary resection and anastomosis;in 45 cases of carcinoma of left colon,primary resection and anastomosis was performed in 37 cases;and emergent(operations) were performed in 10 cases of rectal cancer.23 cases received non-emergency surgery.(Anastomotic) fistula occurred in 3 patients,pulmonary infection in 2 patients,pelvic cavity infection in 1(patient),1 patient died and the rest recovered well and were discharged.Conclusions The initial treatment for acute neoplastic colorectal obstruction should be non-surgcal treatment for 1~3d to make non-emergency surgical treatment more possible.If indications are properly selected,primary tumor resection and anastomosis is safe.For patients with severe contamination of abdominal cavity and bowel perforation, primary tumor(resection) should be performed if possible.

Objective To estimate the prevalence of iron deficiency and its influencing factors in 6 to 12-month-old infants,then more effective community nursing intervention of prevention against iron deficiency can be made.Methods Three hundred and thirty-one 6 to 12-month-old infants had been enrolled by convenience sampling method to complete the investigation.Variables associated with iron deficiency in bivariate analysis were evaluated in Logistic regression models.Results The prevalence rates of iron deficiency in 6 to 12-month-old infants was 34.74％.Anemia,age,feeding patterns and zinc deficiency were independently associated with increased risk for iron deficiency.Conclusions Iron deficiency was common and associated with anemia,low age,feeding patterns and zinc deficiency in a certain community in Tianjin.So effective nursing measures must be made to reduce the prevalence rates of iron deficiency in 6 to 12-month-old infants.

AIM:To determine Radix et Rhizoma Rhici in Ganning Granula(Radix et Rhizoma Rhei,Rhizoma Chuanxiong). METHODS: In order to determine five anthraquinone aglycones of Radix et Rhizoma Rhei,the HPLC system consisted of Nucleosil ODS column,methand-0.1% phosphoric acid(85∶15) mixture as mobile phase,with detection wavelength at 430 nm. RESULTS: HPLC showed that the linearity ranges were as follows: aloe-emodin concentration was at the range of 0.041 6-0.291 2 ?g,the rhein concentration was at the range of 0.037 1-0.259 8 ?g,the emodin concentration was at the range of 0.045 8-0.320 3 ?g,the chrysophanol concentration was at the range of 0.049 60.347 2 ?g,the physcion concentration was at the range of 0.020 6-0.144 5 ?g.The average recoveries of five anthraquinone aglycones were between 96.6%-98.4%.CONCLUSION: The method is simple,accurate,sensible and with good repeatability and can be used for quality control of Ganning Granule.

Objective To investigate the correlation between the number of CD68+ and CD163+ macrophages infiltration and the clinical characteristics of oral squamous cell carcinoma (OSCC),and to investigate the role and significance of CD163+ and CD68+ macrophages in OSCC.Methods Forty-two cases of OSCC resected by operation and diagnosed by postoperative pathology with intact clinical data in our hospitals during 2013-2016 were selected.Other 12 cases of oral mamaxillofacial normal tissue served as controls.The number of CD68+ and CD163+ macrophages infiltration in OSCC was detected by immunohistochemistry.Its correlation with clinical characteristics was analyzed.Results The number of CD68+ and CD163+ macrophages infiltration in OSCC was significantly higher than that in the control group (P<0.05);the infiltration quantity of CD68+ and CD163+ macrophages in poor differentiation and moderate differentiation was significantly higher than that in high differentiation(P<0.05).The number of CD68+ macrophages in lymph node metastasis was significantly lower than that without lymph node metastasis (P<0.05).The number of CD163+ macrophages in the lymph node metastasis was significantly higher than that of CD68+ (P<0.05).The number of CD68+ and CD163+ macrophages had positive correlation in OSCC (r=0.48,P=0.00).Conclusion Tumor-associated macrophages (TAMs) and M2 macrophages may play an important role in OSCC,TAMs may inhibits lymph node metastasis in OSCC,while M2 marcophages may promote the lymphatic matastasis of OSCC.

Objective To observe the features of juvenile obesity and its effect on glycometabolism and lipid metabolism. Methods A total of 194 students aged from 12 to 18 were selected for our study. The assessment included serum lipid concentration, a 75 g OGTT and insulin releasing test. Blood glucose, insulin and the blood lipids were measured. Results Compared with the control group, blood pressure, serum Fins (fasting insulin) and Pins 2h (2-hour postprandial insulin) in the obesity group were higher and were statistically distinguished by the t-test (P

Objective To initially map the gene responsible for autosomal dominant familial IgA nephropathy of a Chinese family by exclusive the five loci that had been reported with linkage analysis.Methods The genetic pattern of the familial IgA nephropathy was identified and the genomic DNA was extracted from the blood samples collected from the family members.Short tandem repeat (STR) inside the loci that had been reported was selected,such as 2q36,3p23-24,4q26-31,6q22-23,17q12-22,and the data with two-point linkage analysis were performed.Results Autosomal dominant inheritance pattern was demonstrated in phenotypes of the family and there was no linkage relationship in the above five loci of chromosomes because the maximum two-point LOD score was 0.39 at D17S1868.Conclusion Following exclusion of the loci which had been reported,there are other new pathopoiesis loci of FIgAN and it reveals that FIgAN has the genetic heterogeneity according to initial result at the same time.
