OBJECTIVE To understand the variance of antimicrobial resistance and the mutations of resistant genes of Mycobacterium tuberculosis isolates in Haiyan area and to be helpful for infection therapy. METHODS For the patients with the positive smears of sputum, the M. tuberculosis was isolated from by sputum. The antimicrobial resistance of the isolates was detected by high and low concentration of antimicrobial agents method. The resistant-genes mutations of rpoB ane katG genes were detected by real-time PCR. RESULTS Among the 131 strains of clinical M. tuberculosis isolates, the total antimicrobial-resistant rate was 14.5%. In the patients after 2 month therapy, the total antimicrobial-resistant rate was 37.8%. The mutations of rpoB ane katG genes were 14.5% and 8.4% in the initially isolated strains, but 39.2% and 25.7% in the strains after 2 month therapy. CONCLUSIONS The drug-resistance of M. tuberculosis isolates in this area existsd before therapy of anti-infection, and,it can increase therapy time. It is important to detect the resistance and the resistant-genes mutations of the isolates.

Objective To evaluate the risk of hyperuricemia in patients younger than 45 with coronary artery disease.Methods Six hundred and seventy-seven patients with coronary artery disease under 45 years old at disease onset were recruited retrospectively.The subjects were divided into hyperuricemia group (n=164) and normal uric acid group (n=513).Patients with coronary artery disease with hyperuricemia were analyzed for clinical characteristics.The risk of hyperuricemia was analyzed on the severity of coronary lesions.T-test,x2 test and Logistic regression analysis were used for statistical analysis.Results Comparing with patients with normal uric acid,patients in the hyperuricemia group were male predominant and more prevalent with hypertension [197(38.5％) and 93(56.7％) ; x2=16.85,P＜0.01],hypedipidemia [274(53.4％) and 130 (80.7％); x2=37.58,P＜0.01],and cardiac dysfunction [24 (4.7％) and 17 (10.4％); x2=7.18,P=0.01].Hyperuricemia increased the risk of coronary artery disease complicated with cardiac dysfunction [ORlcorrection=2.66,95％CI (1.28,5.53)],and it also increased the risk of coronary artery disease concurrent with cardiac arrhythmia [OR2correction=1.28,95％CI (1.00,1.65)] revealed by multivariate regression analysis.Conclusion In young patients under 45 years old with coronary artery disease,hyperuricemia is the independent risk factor for coronary artery disease complicated with cardiac dysfunction and arrhythmia.

Objective: To investigate the effects of PRX-2 gene on phenotype changes in epidermal stem cells differentiating into sweat gland cells. Methods: Epidermal stem cells and sweat gland cells separated and cultured from healthy foreskin and adult full-thick skin respectively, were identified by immunofluorescence staining. Lentiviral vector-mediated overexpression and knockdown of PRX-2 gene in epidermal stem cells were performed respectively, with empty vector-mediated epidermal stem cells as a control group. Overexpression、blank control and knowdown group′s PRX-2 expressions in gene and protein levels were detected using RT-PCR and Western blot technology. The ESCs of each group were co-cultured with sweat gland cells through transwell plate, and the expressions of CEA and β1 integrin in epidermal stem cells were determined by flow cytometry before and after co-culturing. Results: Epidermal stem cells and sweat gland cells were in line with their respective specific antigens. Before co-cultured, epidermal stem cells highly expressed β1 integrin (98.69±0.67)%, hardly expressed CEA (6.20±3.15)%. After co-cultured, β1 integrin expression levels were showed as knockdown group (19.30±0.53)% blank control group (51.20±0.79)%> overexpress group (45.91±0.93)%. There had significant differences between those of each two groups. Conclusions PRX-2 gene can inhibit the phenotypic change of Epidermal Stem Cells differentiating into Sweat Gland Cells and improve the ability to maintain their own specific antigens.

BACKGROUNDReduced endometrial receptivity in hyperstimulated cycles may lead to a lower implantation rate and a lower clinical pregnancy rate, but it is unclear if it is also associated with an increase in pregnancy loss rate. The aim of this study was to compare the implantation, miscarriage, and pregnancy rates between fresh and frozen thawed transfer of one or two day-3 embryos, with a view to understanding whether or not reduced endometrial receptivity encountered in hyperstimulated cycles is associated with an increase in miscarriage rate.

METHODSThis study involved a consecutive series of 1 551 single day-3 embryo transfer cycles and consecutive 5 919 double day-3 embryo transfer cycles in the Assisted Reproductive Unit of the Sir Run Run Shaw Hospital, Hangzhou, China, between January 2010 and December 2012.

RESULTSThe implantation and clinical pregnancy rates (single embryo 30.7% and double embryos 33.4% and 51.4%) using fresh cycle were both significantly lower than that of frozen-thawed cycles (single embryo 35.8% and double embryos 38.1% and 57.8%). There was no difference in biochemical loss or clinical miscarriage rates between the two groups.

CONCLUSIONSImpairment of endometrial receptivity associated with ovarian hyperstimulation leads to implantation failure at a very early stage, resulting in an increased number of non-pregnancy. It does not lead to increase in biochemical or clinical losses. The significantly reduced ongoing pregnancy rates in both fresh single and double embryo transfer are therefore due to failure to achieve a pregnancy, rather than pregnancy loss after conception.

OBJECTIVEThe aim of this study was to assess the feasibility and safety of laparoscopic nerve plane-sparing radical hysterectomy (NPSRH) and compare with that of open NPSRH.

METHODSOne hundred and thirty-four patients with FIGO stage Ib1-IIa2 cervical cancer were enrolled in the study. Thirty-three patients underwent laparoscopic NPSRH. During the operation, the pelvic autonomic nerve plane which is directly underneath the ureter was integrally preserved by dissecting the pelvic spaces laparoscopically. The vessels around the nerve plane were controlled by Hem-o-lok polymer clips. One hundred and one patients underwent open NPSRH without special instruments. The clinical, pathological and surgery-related parameters were compared between the two groups. Moreover, postoperative short-term bladder function of these patients was also analyzed.

RESULTSThere was no significant difference between the laparoscopic group and open group in terms of age, body mass index, previous surgery, FIGO stage, pathologic type, etc. (P > 0.05). The mean duration of surgery in the laparoscopic group was significantly longer [(303.8 ± 67.5) min vs. (272.4 ± 57.5) min] (P < 0.01). But, the laparoscopic group had less blood loss [177.0 ml vs. 474.5 ml, P < 0.01] and blood transfusion rate [ 6.1% (2/33 cases) vs. 49.5% (50/101 cases), P < 0.001]. There was no significant difference regarding the proportion of patients who firstly passed the post-void residual urine volume (PVR) test (P > 0.05). The median time of catheterization between the two groups were also comparable (P > 0.05). However, the postoperative hospital stay was significantly shorter in the laparoscopic group [median postoperative hospital stay 9.2 days vs. 11.0 days, P < 0.001].

CONCLUSIONSLaparoscopic NPSRH is feasible. It seems to be comparable with open NPSRH in terms of preserving pelvic nerve function, but is more favorable in terms of blood loss and postoperative recovery.
