Diabetic nephropathy presents an increasing trend worldwide. It has been an attractive area to find novel targets for the treatment of diabetic nephropathy. SIRT1 (Sirtuin 1), a member of deacetylation enzymes, regulates cell senescence, metabolism, and apoptosis. In last ten years, lots of studies showed that SIRT1 exerts a protective effect in the progression of the diabetic nephropathy by promoting reconstruction of energy homeostasis, modulating cell redox state, resisting cell apoptosis, inhibiting inflammation and ameliorating renal fibrosis. SIRT1 has become a potential new target for the treatment of diabetic nephropathy.

OBJECTIVETo observe the short-term and long-term efficacies on primary dysmenorrhea treated with staging acupoint embedment therapy.
METHODSSeventy cases of primary dysmenorrhea were randomized into an embedment therapy group and a fenbid group, 35 cases in each one. In the embedment therapy group, the embedment therapy was applied twice during the menstrual cycle, one treatment 3 days before menstruation and one treatment during the 12th-14th days of menstruation, respectively. Guanyuan (CV 4), Zigong (EX-CA 1), Diji (SP 8) and Ciliao (BL 32) were the main acupoints in the treatment 3 days before menstruation. Shenshu (BL 23), Ganshu (BL 18) and Pishu (BL 20) were the main acupoints in the treatment during menstruation. In the fenbid group, fenbid was prescribed for oral administration, 0.3 g each time, twice a day, starting 3 days before menstruation till pain was relieved. The treatment of one menstrual cycle was one session. The continuous treatment of 3 menstrual cycles was required. The short-term and long-term efficacies were evaluated at the end of the 3rd cycle and in 3 months after the treatment terminal. The dysmenorrhea score was used to evaluate the efficacy. Visual analogue scale (VAS) and SF-36 were for the assessment of pain degree and life quality.
RESULTS(1) The total effective rate was 91.4% (32/35) in the embedment therapy group after the 3 menstrual cycles, which was better than 74.3% (26/35) in the fenbid group (P < 0.01). In the follow-up stage, the total effective rate was 91.4% (32/35) in the embedment therapy group, which was better than 40.0% (14/35) in the fenbid group (P < 0.01). (2) The differences were not significant in dysmenorrhea score and VAS score after the 1st and 2nd menstrual cycle treatments between the two groups (all P > 0.05). In the 3rd menstrual cycle and the follow-up stage, the dysmenorrhea score and VAS score were reduced obviously in the embedment therapy group as compared with those in the fenbid group (P < 0.05, P < 0.01). The rebound effect occurred in the follow-up stage in the fenbid group. (3) In the 3rd menstrual cycle and the follow-up stage, the improvement in the total score of life quality of the embedment therapy group was superior apparently to the fenbid group (P < 0.05, P < 0. 01).
CONCLUSIONThe staging acupoint embedment therapy achieves the superior short-term and long-term efficacies as compared with the oral administration of fenbid in the treatment of primary dysmenorrhea. As the symptoms of dysmenorrhea and pain are relieved, the life quality is improved.

OBJECTIVETo study operative effects for the treatment of multiple ligament injuries of knee joints.
METHODSFrom 2008 to 2013, 26 patients (17 males and 9 females) with multiple ligament injuries of knee joints were treated surgically. The average age was 40.7 years old, ranging from 29 to 55 years old. All the patients were treated with arthroscopic reconstruction of cruiate ligament with autogenous or allogeneic hamstrings and tendon, and at the same time received repair of medial collateral ligament and lateral collateral ligament, as well as the treatment of exterior and interior complex injuries. Nine patients received second stage operation after the initial operation for mistake or missed diagnosis, and other patients were treated at the first stage. The Lysholm scoring system was used to evaluate function and stability of knee joints before and after operation.
RESULTSAll the patients were followed up for an average duration of 1.6 years (ranged, 0.8 to 3.2 years). The mean awaiting time for operation was 1.2 months. The Lysholm score was improved from preoperative 42.5 +/- 4.5 (ranged, 33 to 48) to the latest follow-up 78.1 +/- 3.9 (ranged, 57 to 95). The function of knee joint was improved obviously in the arthroscopic reconstruction patients, with joint range of motion exceeding 900 and with Varus & Valgus tests near to normal. All the patients had negative findings in the Lachman test at 70 degrees of flexion.
CONCLUSIONArthroscopic reconstruction should be the first choice in treating multiple ligament injuries of knee joints. If the anterior and posterior cruciate ligament injuries can't be treated simultaneously, the posterior cruciate ligament injuries should be treated preferentially at the first stage and the anterior cruciate ligament injuries should be treated at the second stage. The diagnosis of posterior cruciate ligament is easy to be missed.

To establish a detection method of oncolytic adenovirus/p53 and standard of quality control, human telomerase reverse transcriptase (hTERT) promoter, CMV fusion promoter containing hypoxia reaction element (HRE) and p53 gene were identified by vector DNA restriction enzyme digestion and PCR analysis. The result conformed that all modified regions were in consistent with theoretical ones. Particle number was 2.0 x 10(11) mL(-1) determined by UV (A260). Infectious titer was 5.0 x 10(10) IU mL(-1) analyzed by TCID50. In vitro p53 gene expression in human lung cancer cell H1299 was determined by ELISA, and A450 ratio of nucleoprotein in virus infection group to control group was 5.2. Antitumor potency was evaluated by cytotoxicity assay using human lung cancer cell A549, and the MOI(IC50) of this gene therapy preparation was 1.0. The tumor cells targeted replication ability of recombinant virus was determined by TCID50 titer ratio of filial generation virus between human lung cancer cell A549 and human diploid epidermal fibrolast BJ cells after infected by virus with same MOI. TCID50 titer ratio of tumor cell infection group to normal cell infection control group was 398. The IE-HPLC purity of virus was 99.5%. There was less than 1 copy of wild type adenovirus within 1 x 10(7) VP recombinant virus. Other quality control items were complied with corresponding requirements in the guidance for human somatic cell therapy and gene therapy and Chinese pharmacopeia volume III. The detection method of oncolytic adenovirus/p53 was successfully established for quality control standard. The study also provided reference for quality control of other oncolytic viral vector products.

Aspergillus oryzae is an important microorganism,which was widely used in the fields of food,brewing,pharmacy and fermentation industry etc and was termed as a generally regarded as safe(GRAS) organism by the United States Food and Drug Administration(FDA).The strategies for promoting the expression of homologous and heterologous proteins in Aspergillus oryzae were reviewed.Which included the usage of strong promoters,multicopies of coding genes,optimization of culture medium and overexpression of the hemoglobin domains(HBD) etc.Heterologous proteins were usually exhibited low expression in Aspergillus oryzae due to the degradation by the proteinases from host.Therefore,development of proteinase auxotrophic stains of Aspergillus oryzae as host is neccessary.In addition,fusion of the heterologous protein with a highly secreted protein of Aspergillus oryzae was an alternative way to prompt the expression of heterologous protein in Aspergillus oryzae.

Background The filtering surgery is the main method of treating glaucoma.Fibrosis of filtering bleb is a key cause of failure of operation.The study about application of anti-scaring drug in filtering surgery is a hotspot.Objective Present study was to investigate the anti-scaring effect of paclitaxel aher trabeculectomy.Methods Thirty-two adult clean domestic rabbits underwent standardized trabeculectomy and randomly divided into 4 groups.Normal saline solution was used beneath the scleral flap during trabeculectomy for 3 minutes in 16 eyes of 8 rabbits as controls.0.3 g/L mitomycin C,0.2 g/L paclitaxel or 0.3 g/L paclitaxel was administered at the same way respectively in other 3 groups.Intraocular pressure (IOP) was measured,and eye numbers with function blebs were compared among 4 groups at the 4th,7th,14th and 28th day after surgery.The opening of filtration tunnel and the number of inflammatory cells were observed by hematoxylin and eosin staining,and proliferation of new collagen fibers was evaluated by Masson trichrome method.This study complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission(version 1988). Results No significant differences were found in the change of lOP among 4 groups before operation(F=0.54,P=0.83)and the 4th day aher operation(F=0.57,P=0.87).The IOP value was statistically lower in 0.3 g/L mitomycin C group,0.2 g/L paclitaxel group and 0.3 s/L paelitaxel group than the normal saline solution group(P<0.05)with the lowest value in 0.3 s/L paclitaxel group in 7,14,28 days after operation(P<0.05).Functional filtering bleb was seen in all the rabbit eyes in the 4th day after operation.In 7,14,28 days after operation,the number of eyes with functional bleb wag evidently more in 0.3 g/L mitomycin C group,0.2 g/L paclitaxel group and 0.3 g/L paclitaxel group compared with normal saline group(P<0.05).The histological examination showed that the infiltration of inflammatory cells in filtering tunnel was much more obvious in normal saline solution group than the other groups with the most mild response in 0.3 g/L paclitaxel group.Masson trichrome revealed that proliferation of new collagen fibers in 0.3 g/L paclitaxel group was significantly decreased in comparison with those in other three groups at the 4th,7th,14th and 28th day after surgery(all P<0.05). Conclusion Paclitaxel can inhibit the inflammatory response and collagen fibrosis and therefore open the filtering tunnel after it be used topically during the glaucoma trabeculectomy.
