Objective To study antimicrobial resistance and genotyping of methicillin-resistant Staphylococcus au-reus(MRSA). Methods A total of 967 no-repetitive strains of Staphylococcus aureus(S.aureus)isolated from a hospital between January 2014 and November 2015 were collected,antimicrobial susceptibility testing,mecA gene,and Panton-Valentine leukocidin gene(PVL gene)were detected;staphylococcal cassette chromosome mec(SCCmec)typing,multilocus sequence typing(MLST),S.aureus protein A(spa)gene typing,and S.aureus ac-cessory gene regulator(agr)typing were performed with multiplex polymerase chain reaction. Results Of 967 strains of S.aureus,210(21.72%)were MRSA;detection rate of MRSA from sputum specimen was higher than that of skin and soft tissue specimen(68.09% vs 1 1.83% ,P<0.05);vancomycin- and linezolid-resistant S.aureus strains were not found,susceptibility rates of MRSA to gentamicin,tetracycline,erythromycin,clindamycin,levo-floxacin,ciprofloxacin,moxifloxacin,nitrofurantoin,and rifampicin were all lower than those of methicillin-sensi-tive Staphylococcus aureus(MSSA),differences were all statistically significant(all P<0.05);antimicrobial sus-ceptibility rate of MRSA to compound sulfamethoxazole was higher than MSSA,difference was significant(P<0.05). Susceptibility rates of MRSA isolated from skin and soft tissue to gentamicin,levofloxacin,ciprofloxacin,moxifloxacin,and rifampicin were 86.90% -95.24%,while MRSA isolated from sputum were only 1.56% -15.63%.Of 967 strains of S.aureus,210 harbored mecA gene,10 harbored PVL gene,8(3.81%)of 210 MRSA strains weren't typed. The main types of MLST,SCCmec,spa,and agr were ST 239(n= 177 strains),type Ⅲ(n= 177 strains),t 030(n= 177 strains),and typeⅠ(n= 196 strains)respectively.Conclusion The main epidemic clone of MRSA strain in this hospital is ST239-MRSA-SCCmec III-t030,antimicrobial resistance is serious,monitoring on drug-resistant strains in hospital should be strengthened.

OBJECTIVETo investigate the effect of triptolide (TPL) on the renal tissue of diabetic rats and its possible mechanisms.

METHODSSD rats were randomly divided into the normal control group (as the normal group), the diabetic model group (the model group), the low dose TPL treatment group (the low dose TPL group, TPL 0.2 mg/kg by gastrogavage), the high dose TPL treatment group (the high dose TPL group, TPL 0.4 mg/kg by gastrogavage). Equal volume of normal saline was given to rats in the normal group and the model group. Five rats were randomly selected from each group at week 4, 8, and 12 of the experiment to detect body weight, kidney weight, 24 h urinary albumin (24 h UAL), plasma glucose (FBG), total cholesterol (TC), total triglyeride (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), white blood cell (WBC), and hemoglobin A1c (HbA1c). The mRNA and protein expression of regulated upon activation normal T-cell expressed and secreted (RANTES) in the renal tissue was assessed by reverse transcription-polymerase chain reaction (RT-PCR) and enzyme linked immunosorbent assay (ELISA). The renal tissue was pathologically stained by HE, PAS, and Masson staining. The glomerular and renal tubular interstitial lesions were observed at each time point. The glomerular sclerosis index (GSI) was observed by PAS staining, and the renal interstitial filrosis index (RIFI) was calcutated.

RESULTSCompared with the same group at week 4, the expression of 24 h UAL, RANTES, GSI, and RIFI at week 12 significantly decreased in two TPL groups (P <0.01). Compared with the same group at week 8, the expression of 24 h UAL, RANTES, GSI, and RIFI at week 12 also significantly decreased in the two TPL groups (P <0. 05, P <0.01). Compared with the normal group, body weight and the kidney weight obviously decreased at week 4, 8, and 12 in the model group (P <0. 01); 24 h UAL, FBG, TG, TC, HbA1c, RANTES, GSI, and RIFI were obviously elevated (P <0.01). Compared with the model group, 24 h UAL, RANTES, GSI, and RIFI also decreased in the two TPL treatment groups (P <0.01). Compared with the low dose TPL group, they were attenuated in the high dose TPL group (P <0. 05, P <0. 01).

CONCLUSIONTPL could not only inhibit the over-expression of RANTES, but also improve the glomerular sclerosis and renal interstitial fibrosis in the renal tissue of diabetic rats.

OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

A strain Escherichia coli with high production of phytase was screened from pig excreta. Phytase gene appA, with 1,299 bp coding region in full length, was cloned from its genome by polymerase chain reaction (PCR) . The gene appA was then cloned into the prokaryotic expression vector pET-28a ( + ) . In the host BL21, the phytase appA was overexpressed by shaker-cultivation (up to 692 U/mL) . The enzymatic analysis of the prokaryotic derived appA phytase revealed that its optimal pH and temperature was 4.5 and 60℃, respectively.

A fusion protein of glucagons-like peptide-1 and human serum albumin (GLP-1/HSA) was expressed and secreted into the fermentation broth with recombinant Pichia pastoris. The productivity of expressed GLP-1/HSA could reach 63.6mg/L in 10L fermentor. After concentrated with hollow-fiber ultrafiltration membrane, GLP-1/HSA was purified from fermentation broth by hydrophobic chromatography, negative ion exchange chromatography and gel filtration chromatography in turn. The HPLC analysis showed that the purified GLP-1/HSA had an overall purity of 95.8%. Furthermore, the analysis of in vivo activity indicated that GLP-1/HSA had the bioactivity of native GLP-1, and could significantly reduce blood glucose level 4h after intraperitoneal administration. It was concluded that a great deal of GLP-1/HSA with higher purity could be harvested by Pichia pastoris expression system and the established purification methods. Preliminary studies show a new potential for developing the long-acting GLP-1 analogs for clinical applications.

Objective To investigate reliability of the infra-nipple broken line incision for breast augmentation.
Methods From January 2012 to January 2013, 15 patients underwent primary bilateral retromuscular breast augmentation with round textured silicone-gel implants and a novel infra-nipple broken line incision. Preoperatively, a semicircular incision was marked along the inferior base of the nipple. It was then extended bilaterally using two transverse right-angled geometric broken lines within the pigmented areolar skin. Follow-up was performed to evaluate the sensation of nipple-areolar complex, the scar, and the shape and texture of the breasts.
Results The average follow-up was 6.7 months. Most of the patients complained of paresthesia of the nipple or breast skin, but transient decreased sensation improved within 3 months. No patients showed permanent sensory changes of the nipple areolar complex at a minimum follow-up of 4 months. The scars were imperceptible in all patients.
Conclusion We believe that for selected patients, the infra-nipple broken line incision is a practical and reliable method to achieve aesthetic result.
