OBJECTIVETo evaluate clinical results of plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot.

METHODSSeven patients (9 feet) patients with tarsometatarsal joint dislocations secondary to diabetic charcot foot were treated with plating from April 2012 to December 2014. All patients were male, and 5 cases were on the unilateral side and 2 cases were on the bilateral sides. The age of patients ranged from 45 to 52 with an average of 48 years old. The history of diabetics was from 6 to 15 years. X-ray and CT were used to evaluate fractures healing,and AOFAS was applied to estimate recovery of joint function.

RESULTSAll patients were followed up from 12 to 24 months with an average of 19 months. All incisions were healed at stage I . No infection, loosening and breakage of internal fixation, bone nonunion were found after operation. According to postoperative X-ray and CT results, the time of fracture healing ranged from 10 to 20 weeks with an average of 16 weeks. Six feet got excellent results, 2 good and 1 moderate based on AOFAS scoring.

CONCLUSIONTarsometatarsal joint dislocations secondary to diabetic charcot foot treated with plate on the metatarsal side could obtain stable fixation and got satisfied early clinical results.

BACKGROUND: The application of mesenchymal stem cells derived from umbilical cord cultured in serum-containing medium has some obstacles. OBJECTIVE: To establish serum free medium system for primary culture of umbilical cord-derived mesenchymal stem cells. METHODS: Wharton’s Jel y was isolated from umbilical cord, minced, 1-3 mm3, and subsequently incubated in either serum containing medium or serum free medium. Some cells were harvested on days 11, 14 and 17 for some detection. Based on the minimal criteria established by the International Society for Cel ular Therapy in 2006, mesenchymal stem cells were assayed with colony forming unit-fibroblast. RESULTS AND CONCLUSION: The mesenchymal stem cells grew rapidly in serum free medium condition compared with serum containing medium. On day 11, the number of colonies was larger in serum free medium condition than that in serum containing medium. Thus, serum free medium could maintain properties of mesenchymal stem cells and provide possibility a credible alternative to serum containing medium for primary culture of umbilical cord-derived mesenchymal stem cells.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.

Objective To increase the awareness of virus-associated hemophagocytic syndrome.Methods Sixteen cases of virus-associated hemophagocytic syndrome were retrospectively analyzed.Results All presented with persistent high fever,cytopenia,hepato-splenomegaly,hepatic dysfunction,hypertriglyceridemia,hyperferritinemia,coagulopathy,hypofibrinogenemia,cytokine storm and a low natural killer cell activity.All patients had lymphohistiocytic accumulation in bone marrow.Treatment with high-dose gamma-globulin and high-dose methylprednisolone.Clinical symptoms and laboratory improved,and five patients died.Conclusion Aggressive early diagnosis and treatment are critical to improve survival.

Objective To review the effect of exposed and buried Kirschner wire fixation of lateral humeral condyle fracture in children.Methods Randomized control trials (RCTs) about exposed versus buried Kirschner wire fixation of lateral humeral condyle fracture in children were identified through electronic search using the Cochrane Collaboration search strategies and manual search.Electronic database included Cochrane Library,Medline,PubMed,CBM,VIP,CNKI,Wanfang database and other Chinese and English database.Manual research included related journals and conference proceedings.Quality analysis of the included literatures was performed using the methodological index for non-randomized studies (MINORS).RevMan 5.3 software was used for Meta analysis.Results Four studies involving exposed Kirschner in 150 cases and buried Kirschner in 351 cases were included.The two techniques were similar with respect to postoperative infection (OR =1.10,95％ CI 0.52 ～ 2.33,P ＞ 0.05),superficial infection (OR =1.45,95 ％ CI 0.66 ～ 3.18,P ＞ 0.05),reoperation rate (OR =2.29,95％CI 0.51 ～ 10.25,P ＞0.05),delayed union rate (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞0.05) and total complications (OR =1.57,95％ CI 0.76 ～ 3.21,P ＞ 0.05).However,Kirschner wire exposure shortened the time of pulling out Kirschner wire (MD =-13.28,95％ CI-16.42 ～-10.14,P ＜0.05).Conclusion Applied for lateral humeral condyle fracture in children,exposed versus buried Kirschner wire fixation results in short Kirschner wire stabilization time that avoids local anesthetic and cost while pulling out Kirschner wire in the late stage.

Objective To quantify aqueous flare and cells in the eyes of healthy subjects and to evaluate the effect of age and sex on the blood aqueous barrier. Design Prospective case series. Participants Four hundred and forty-two eyes of 221 healthy sub- jects. Methods Aqueous flare and cells of 442 eyes were evaluated with FC-2000 laser flare cell meter (LFCM). Main Outcome Mea- sures Aqueous flare and cells. Results The mean flare values of all of eyes was 4.7?2.9 pc/ms, it was 3.1 pc/ms in the age group of less than 10 years, 3.8 pc/ms in the age group of 40-49 years and 11.0 pc/ms in the age group of 80 years or over. The mean flare val- ues in the age groups of 50 years or over were significantly higher than that in the age group of 40-49 years (P
