BACKGROUND:The mesh size used for herniorrhaphy mainly depends on clinicians' experience, which is less reliable. OBJECTIVE:To obtain the mesh size by measuring the posterior wall of inguinal hernia in Chinese adult men undergoing Rutkow surgery, and to assess the postoperative effect. METHODS:The posterior wall size of inguinal hernia in 180 Chinese adult male patients undergoing tension-free hernioplasty was measured, and then the optical mesh size was calculated. All patients were equivalently randomized into two groups, followed by subjected to Rutkow surgery according the calculated mesh size (experimental group) or subjective size (control group). Clinical indexes, the incidence of complications and recurrence rate were compared between groups. RESULTS AND CONCLUSION:The distance of pubic tubercle to internal oblique inguinal ligament starting point was (6.03±0.58) cm;the vertical distance of the highest point on the edge of the arcuate to inguinal ligament was (3.02±0.32) cm;therefore, the length of mesh should be larger than (13.04±0.74) cm, and width larger than (5.88±0.52) cm. The time of off-bed, dieting and hospitalization in the experimental group were significantly less than those in the control group (P<0.05);the time of operation and recovery of normal activities showed no significant difference between groups (P>0.05). The rates of postoperative complication and recurrence in the experimental group were significantly lower than those in the control group (P<0.01). These results suggest that after measuring the posterior wall size of inguinal hernia, the Rutkow used for inguinal hernia repair, obtains desired treatment outcomes with low incidence of complications and recurrence.

Objective To explore the relationship between leadership of head nurses and nurse job satisfaction. Methods By generalized stratified sampling, 207 nurses who were in accordance with the inclusion were selected from 2 hospitals in China. To evaluate leadership of head nurses that selected nurses perceived and the status of their job satisfaction, they were asked to complete a questionnaire consisting of transactional subscale and transformational subscale of MLQ, and job satisfaction measurement scale. Results Head nurses were more frequently to be transactional than transformational, and frequencies between the two kinds of leadership that head nurses showed had significant difference. Regarding job satisfaction, nurses had the highest score in colleague and the lowest score in payment. transformational leadership was one of the influential factors on nurse job satisfaction, and were positively correlated with the overall nurse job satisfaction, satisfaction with leaders, satisfaction with communication. Conclusions Head nurses can improve nurse job satisfaction by being more transformational.

Traditional immunological strategy which largely based on antigen-antibody techniques such as CA153,cytokeratin CK8/18/19,is still the main diagnostic biomarkers for breast cancer.Molecular biology markers such as BRCA1/2 and HER2 are becoming popular and hot.This article summarizes recent progress of breast cancer diagnosis based on nucleic acid related strategies such as circulating DNA,miRNAs,aptamers and circulating tumor cells.

Using metnod of literature metrology, an analysis of papers citations in "Chinese Journal of Marine Drugs" from 1989 to 1993 was done. During the period there were altogether outgoing papers 181,papers citations 1301. The average values were each paper citations 7. 98. Among the rate of self-citation was 12. 76%. In the all citation, periodical 65. 1% ,books 27. 6% ,others 7. 3%. The languages ditiributions:Chinese 65. 72%, English 28. 13%,Japanese 5. 07%,Russian 0. 08%. The use rate of literature,Chinese 83. 27% ,and Foreign 45. 74% ,during the past 10 years. Papers citatians indicate that the marine drugs science workers of China can absorb consciously the information on science and technology of marine drugs.

AIM To explore the protection effect of Blood-Replenishing Capsule (BRC) on hypoxic animals in order to lower the rate of altitude stress. METHODS Comparison of BRC on survival time of mice under ordinary pressure and chemical hypoxia were observed and the oxygen consumption was measured. RESULTS BRC-obviously prolonged the survival time of hypoxic mice, reduced the oxygen consumption and increased the hemoglobin (Hb) content in the bloods.Mouse brain's SOD was obviously higher and MDA concetration remarkable lower in BRC groups than those in control groups. CONCLUSION BRC shows remarkable effect on hypoxia tolerance in mice.

Objective To perform fetal karyotyping by percutaneous umbilical blood sampling guided by color Doppler ultrasonography in fetuses with congenital cardiac anomalies. Methods Fetal blood samples obtained by color Doppler ultrasound-guided cordocentesis in 56 fetuses with cardiac abnormalities detected by fetal echocardiography were taken for karyotyping.Fetuses were monitored post operation. Results The procedures were successfully performed in all cases and no procedure-related complications occurred.Six cases with abnormal karyotypes, 1 trisomy 21,2 trisomy 18,1 trisomy 13,1 trisomy AO and 1 cases 47XYY were identified and pre-operation ultrasonography detected multiple system anomalies besides cardiac anomalies in them. Conclusions Color Doppler ultrasonography facilitated percutaneous umbilical blood sampling by clear umbilical vein imaging and shortening the operation time.Abnormal karyotypes in fetuses with cardiac anomalies seemed to be related with multiple system anomalies.

1?g/ml)could inhibit osteoblasts to grow and proliferate, and showed cytotoxic activity. Conclusion aFGF possesses the effect of triggering osteoblasts to grow and proliferate, and its effective concentration is 10-100 ng/ml.

Paraneoplastic pemphigus(PNP) is a clinically, histologically, and immunopathologically distinct autoimmune bullous disease characterized by severe painful mucosal erosions and polymorphous skin lesions. Histopathology shows acantholysis with lichenoid dermatitis or keratinocyte necrosis, and there are autoantibodies to various epidermal proteins with underlying neoplasia. We report two cases of paraneoplastic pemphigus in China firstly. The clinical, histologic, and immunopathologic findings of both cases strongly suggest the diagnosis of paraneoplastic pemphigus associated with Castleman′ s tumor.

Objective To compare the degrees of stress reaction among laparoscopic cholecystectomy(LC),mini-incision open cholecystectmy(MIOC) and conventional open cholecystectomy(OC).Methods Ninety patients with gallstone were randomly divided into three groups:(LC),(MIOC) and (OC).Blood Thyroxin(T 3),throid-stimulating hormone(TSH),cortisol,insulin,glucose,white blood cell and temperature were measured and/or recorded in the perioperative period.Results The stress rection in LC was significantly lighter than that in OC,but the stress reaction degree in LC and MIOC were basic equality.Conclusion The stress reaction in LC is small than those of OC.
