Stoma has been used in colorectal surgery for various indications. Stoma type and stoma location are associated with stoma complications and quality of life with a stoma. The question regarding how to avoid stoma complication and improve quality of life should be considered when stoma creation is planned. The benefit of stoma should be balanced with complications brought about by stoma creation.

Despite progress in the understanding of perirectal anatomy and subsequent adoption of total mesorectal excision,local recurrence after curative resection for rectal cancer continues to be a significant concern.Local recurrence of rectal cancer is associated with a wide spectrum of clinical symptoms and morbidities,and decreased quality of life.The management of locally recurrent rectal cancer is challenging because of the altered pelvic anatomy,postoperative adhesion and difficulty in obtaining a definite diagnosis before surgery.Surgery is the mainstay treatment for locally recurrent rectal cancer,and the use of radiation and chemotherapeutic agents provides significant improvement in survival rate and quality of life.

Pro-prostate-specific antigen (proPSA) is the precursor of PSA and a form of free PSA (fPSA). In recent years, a lot of studies have been done on proPSA, the roles of its related indexes in the diagnosis of prostate cancer, and the value of its clinical application. The correlated indexes of proPSA include proPSA, % pPSA, p2PSA, % p2PSA and prostate health index (PHI). They are more effective than total PSA (tPSA) and fPSA in the diagnosis of prostate cancer, especially % p2PSA and PHI, which may significantly increase our ability to detect and identify PCa and lower the rate of unnecessary biopsies. This article presents an overview on the advances in the studies of proPSA and the application of its related indexes in the diagnosis of prostate cancer.

Background C57BL/6.NOD-Aec1Aec2 mouse is considered to be an idea model for the study of the pathogenesis of Sj(o)gren syndrome,but the cause of dry eye in these mice is unclear.Objective This study was to investigate the histopathological change of the ocular surfaces of C57BL/6.NOD-Aec1Aec2 mice,and to determine whether dry eye is developed spontaneously in these mice.Methods Forty-five clean C57BL/6.NOD-Aec1 Aec2 mice were used as the experiment group and forty-five C57BL/6J mice(both male and female)were used as the control group in this study.Detection of fasting blood-glucose,Schirmer' s test Ⅰ (S Ⅰ t),lissamine green staining and scoring of the corneal and conjunctival epithelium in the mice were performed at the age of 4,8,12,16 and 20weeks.Five mice from each group were sacrificed and their corneas were obtained to measure the central corneal epithelium thickness and to count the number of conjunctival goblet cells.In addition,lymphocyte infiltration in the lacrimal gland of the mice was examined with hematoxylin-eosin staining.The uhrastructure of the corneal epithelial cells and microvilli were assessed by scanning electron microscopy.The use and care of the mice were approved by the Experimental Animal Care Committee of the Third Military Medical University.Results No sign of dry eye was seen in both the 4-week-old C57BL/6.NOD-Aec1Aec2 mice and 4-week-old C57BL/6J mice.The S Ⅰ t values in 8-week-old,12-week-old,16-week-old and 20 week-old mice from the experiment group were (2.7 ±0.9) mm,(2.5 ±0.8) mm,(1.8±0.6) mm and (1.9± 0.1) mm,respectively,showing a significant reduction in comparison with those of the control mice of the same age(all P＜0.01).The amount of lissamine green staining in the C57BL/6.NOD-Aec1Aec2 mice gradually increased with age,showing elevated scores in 12-week-old,16-week-old and 20-week-old mice in the experiment group(all P＜0.01).The central corneal epithelium thicknesses were(20.18±3.75)μm,(17.01 ±5.25) μm,(14.19±5.72) μm and(12.00±3.25) μm in the 8-week-old,12-week-old,16-week-old and 20-week-old C57BL/6.NOD-Aec1Aec2 mice,respectively,which were significantly lower than those of the C57BL/6Jmice of the same age (all P＜0.01).The numbers of conjunctival goblet cells were (8.2±2.4),(6.2±2.1),(6.1 ±2.2) and (4.1 ± 2.0) in the 8-week-old,12-week-old,16-week-old and 20-week-old C57 BL/6.NOD-Aec 1Aec2 mice,respectively,showing a gradual decrease with age and a significant decline in comparison with those of the C57BL/6Jmice of the same age(all P＜0.01).Lymphocyte infiltration in the lacrimal gland and destruction of gland ducts were seen by hematoxylin-eosin staining,and acinar abnormality aggravated with aging.Reduction of corneal epithelial cells and the number of microvilli were distinguished with aging under the scanning electron microscope.The fasting bloodglucose levels of the two groups were both less than 6.0 mmol/L,and no significant difference was found between them at any age(P=0.637,0.610,0.163,0.086,0.938).Conclusions C57BL/6.NOD-Aec1Aec2 mice develop dry eye spontaneously with aging.The course of disease and characteristics of dry eye in C57BL/6.NOD-Aec1Aec2mice is similar to human dry eye.The C57BL/6NOD-Aec1 Aec2 mouse is the perfect model to study the pathogenesis of dry eye.

OBJECTIVE To investigate the drug-resistance of ESBLs-producing Escherichia coli for guiding the clinical drug-using.METHODS The Kirby-Bauer agar diffusion method was used to analyze the drug resistance of 68 E.coli isolates in these three years.The ESBLs-producing strains were detected by confirmed test.RESULTS Thirty one ESBLs-producing strains were detected and the isolated rate was 54.4%;the resistant rates of these isolates were up to 50% to penicillin and three generations cephalosporin.The resistant rate to quinolone was about 70%.All of the strains were susceptible to imipenem.CONCLUSIONS More attention should be paid on the detection of ESBLs-producing E.coli and prevent the prevalence of the drug-resistant strains.

Objective To explore the relation between endothelial function and Alzheimer′s disease(AD).Methods The concentration of asymmetric dimethylarginine(ADMA)and L-arginine were measured by high-performance liquid chromatography(HPLC),the concentration of nitric oxide(NO) detected by the method of nitrate reductase,and the activity of nitric oxide synthase(NOS)examined using NOS assay kits,in the plasma of 45 mild/moderate AD patients and 48 controls.Results Compared with controls,the concentration of ADMA(0.95?0.09?mol/L,P=0.00)was significantly increased,however the activity of NOS((13.9?3.9)U/L,P=0.00),inducible NOS(iNOS)((5.1?1.8)U/L,P= 0.00)and concentration of NO((41.7?5.0)?mol/L,P=0.00)were significantly decreased.In addition,Logistic regression analysis found significant positive correlations between the plasma concentration of NO and the score of the CDR(y=36.64?0.398_x;r=0.398,P

A questionnaire survey on awareness of child health management was conducted in 238 family members ( 236 were parents) of children aged 0 - 36 months; among whom 92 of children aged 0 to 6 months,85 of children aged 7 to 12 months,33 of children aged 13 to 18 months,16 of children aged 19 to 24 months and 12 of children aged 24 to 36 months.52.1％ of the surveyees had college education level.The awareness about medical examination in last half year in female subjects was higher than males ( P ＜ 0.05).There were no differences in other health management knowledge.The results showed that the average times of medical examination was 2.8 ± 1.9 in last half year; the age for supplement of meat in food was 7.4 ± 2.4 mouths; supplement of meat,animal liver and eggs was more than 7 time a week.The subjects with college education or above paid more attention to the children's growth,risk for rickets and anemia than other peoples.Pure breast feeding accounted for only 37.0％ (88/238).The study indicates that strengthening the knowledge and awareness is necessary to improve the children health management.
