Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.

AIM: To observe the therapeutic effect and safety of improved extra panretinal photocoagulation ( E - PRP) in the treatment of high risk proliferative diabetic retinopathy (hsPDR).
METHODS: A total of 88 consecutive cases (102 eyes) with hsPDR were diagnosed by fundus fluorescein angiography(FFA) from February 2011 to December 2014 in our hospital . Fifty two eyes had been treated by improved E - PRP with 532nm frequency - doubled laser. Fifty eyes had been treated by standard PRP. All cases were checked by FFA and fundus photocoagulation every 3mo. Patients with persisting neovascularization or non perfusion area were treated with laser again. All cases were followed up 6-36mo.
RESULTS: The postoperative visual acuity had no statistical difference between two groups ( P > 0. 05). In improved E - PRP group, retinal non perfusion area and neovascularization disappeared in 35 eyes ( 67%). Effective rate was 88%. Six eyes (12%) underwent pars plana vitrectomy because of vitreous hemorrhage, fiberosis and stretched retinal detachment. In standard PRP group, retinal nonperfusion area and neovascularization disappeared in 23 eyes ( 46%). Effective rate was 66%. Seventeen eyes(34%) underwent pars plana vitrectomy because of anterior retina bleeding or vitreous hemorrhage. The rate of neovascularization disappeared and effective rate had statistical difference between two groups (P<0. 05).
CONCLUSION: It is a safe and effective methods to treat hsPDR by improved E-PRP and it was more effective than traditional PRP.

Objective To evaluate the preoperative nutritional status of patients with gastric cancer by using patient-generated subjective global assessment (PG-SGA) its relationship with postoperative results.Methods Make a preoperative nutrition assessment by using PG-SGA for 87 patients with gastric carcinoma who can be treated with operation.Analyze the effects of the postoperative complication,survival rate and the hospitalization time on patients.Results The number of patients of this group who can process the preoperative nutrition assessment by using PG-SGA accounts for 100％ of the total.There are 37 patients with moderate or severe malnutrition before operation (account for 39.1％).The complication incidence of patients with moderate or severe malnutrition before operation and the patients with no or mild malnutrition are 52.9％ and 5.7％ separately (P ＜ 0.01).The sensitivity and specificity of PG-SGA score for predicting complications are 85.7％ and 75.8％ respectively.And we should implement the analysis of regression to verify that the PG-SGA grade is the independent risk factor of postoperative complication by applying multiple Logistic(P ＜ 0.01).The average hospital stays of patients with moderate or severe malnutrition before operation and the patients with no or mild malnutrition are (21 ± 6) d and (16 ± 4) d separately (P ＜ 0.01).Conclusion According to the PC-SCA results,patients with moderate or severe malnutrition before operation have increased susceptibility to complication and the extension of hospital stays after the operatiou.Therefore,it is important to supply the proper nutrition support to these patients.

Objective To observe the clinical efficacy of Zhishanghan Zhufeng Formula in treating knee osteoarthritis.Methods Totally 90 patients were randomly divided into treatment group and control group, 45 cases in each group. The treatment group was treated with Zhishanghan Zhufeng Formula for 30 days. The control group was treated with routine medicine (diclofenac sodium sustained release tablets and glucosamine sulfate tablets) for 30 days. The clinical efficacy and the changes of VAS, WOMAC score and knee temperature before and after treatment of two groups were observed.Results TCM clinical symptoms were significantly improved, and the effects in the treatment group were more evident compared with the control group (P<0.05). After treatment, VAS and WOMAC score of the two groups decreased obviously, while the knee temperature increased, and the treatment group was superior to the control group, with significant significance (P<0.05).Conclusion Zhishanghan Zhufeng Formula has effective clinical efficacy for knee osteoarthritis.

Objective:To investigate whether transplantation of mesenchymal stem cells(MSCs)through renal arteries can protect kidney from acute tubular necrosis(ATN),so as to lay a foundation for MSC transplantation in treatment of ATN.Methods:Five-week-old nude mice were randomly divided into three groups:normal control group(n=10),acute tubular necrosis(ATN)model group without(n=10)and with MSCs treatment group(n=11).ATN nude mice were induced with 50% glycerin.MSCs labeled with enhanced green fluorescent proteins(EGFP)were injected into kidney through renal arteries.Serum creatinine was determined in all groups and pathological changes of renal tissues were detected using H-E staining.The amount and distribution of the EGFP-marked MSCs in renal tissues were determined with fluorescence microscope.Results:Degeneration and exfoliation of renal tubular epithelial cells,and even renal tubular tamponade with cast-off cells were observed in the ATN group;these pathological changes were mainly located at renal cortex and juncture of renal cortex and medulla.The damages were greatly alleviated in the ATN+MSCs transplantation group,with no swelling of epithelial cells,nuclear condensation or edema.Fourteen days after MSCs transplantation,EGFP positive cells were increased in renal tubules of recipient mice.Conclusion:The MSCs transplantation via renal artery can locate in renal tubular epithelium,and promote the repair of injured renal tubular epithelial cells.

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

Objective To investigate clinicopathologic characteristics of obsolete Bennett fractures and their surgical treatment and prognosis. Methods From August 2008 to April 2010,13 patients with obsolete Bennett fracture were admitted to our department.They were 12 men and one woman,with an average age of 34.3 years (from 17 to 42 years).They had a fracture history of over 4 weeks to as long as 12 weeks (average,7.9 weeks).In all patients,after X-ray examinations,the radio-dorsal ligament complex of the first carpometacarpal joint was properly released,fracture gaps were cleared up,fracture fragments were anatomically reduced and fixed with a Kirschner wire,and at last the first metacarpal joint was fixed with the Kirschner wire crossing the joint Postoperatively all patients were immobilized with cast plaster for 4 weeks before the Kirschner wires acrross the joint were removed.Gradual rehabilitation was conducted.The X-rays were taken every month. Results The patients were followed for 6 to 24 months(average,14 months).The fractures healed in all the patients,with an average healing time of 3 months.No dislocation of the joints occurred.Injury to articular cartilage of the trapezium bone occurred in one patient,and no apparent pain was experienced in the other 12 patients.According to the Total Active Motion assessment,the thumb function was rated as excellent in 9 cases,good in 2,moderate in one and poor in one,with a good to excellent rate of 84.6％.Conclusions In obsolete Bennett fractures,the radio-dorsal ligament complex of the first carpometacarpal joint will have cicatricial contracture,preventing reduction of the fragments of the radio-dorsal joint.Therefore it is important to properly release the radio-dorsal ligament complex to achieve anatomical reduction of the radio-dorsal joint.An injury history of over 3 months and complicated injury to the trapezium bone cartilage may be significant factors affecting the prognosis of obsolete Bennett factures.
