Objective To reconstruct skin defects with local flaps after resection of tumors. Methods From October 2006 to December 2009, medial canthal defects in 15 patients were repaired with local flaps in the hospital. The size of the defects varied from 1 cm × 1 cm to 1.8 cm × 2.0 cm. According to the size and location of the defects, different local flaps such as glabellar flaps ,rotation flaps, advancement flaps, nasolabial flaps and combination of these local flaps were selected and designed to repair the skin defects. Results Of the 15 patients, 12 received the reconstruction of skin defects with single flap, the other 3 with two flaps; totally,18 local flaps were designed and applied. All the flaps survived with primary healing postoperatively. A followup in 11 patients for 6 to 12 months showed that the color and texture of flaps were similar to those of surrounding tissues and incision line scar was inconspicuous. Medial canthal contours were restored without distortion of surrounding structures. Satisfactory function and aesthetic outcomes were achieved. Conclusions In the repair of inner canthus skin defects, to maintain and restore the "cosmetic unit" integrity of inner canthus by using suitable local flaps would lead to a satisfying restoration of function and appearance.

OBJECTIVETo discuss operative methods and effects for Müller-Weiss disease.
METHODSFrom March 2005 to May 2011, 15 patients were operated. There were 2 males and 13 females, with an average age of 51.8 years (range, 26 to 62 years). The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was (42 ± 13) points. According to the Maceira Staging system, 1 foot was grade 2, 6 feet were grade 3, 4 feet were grade 4, and 4 feet were grade 5. The technique consisted of arthrodesis of the talonaviculocuneiform joints with plate, arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint with plate, or triple arthrodesis with screws, according to the preoperative evaluation.
RESULTSTen feet were treated with arthrodesis of the talonaviculocuneiform joints, 3 feet were treated with arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint and 2 feet were treated with triple arthrodesis. Two patients were lost to follow-up. The average follow-up after operation was 19.2 months (range, 9 to 38 months). All feet were solid fusion and the average duration of union was 13.3 weeks (range, 12-16 weeks). The AOFAS ankle-hindfoot score at the last follow-up was (83 ± 6) points. Two feet were excellent, 10 feet were good, and 1 foot was fair. The length of feet was (14.2 ± 1.0) cm before surgery and (15.7 ± 0.9) cm at the last follow-up (t = 11.570, P < 0.05). The Meary's angle was -6.1° ± 13.1°before surgery and 1.1° ± 3.0° at the last follow-up (t = 2.248, P < 0.05). The talocalcaneal angle was 4.5° ± 2.2° before surgery and 18.0° ± 4.0° at the last follow-up (t = 11.700, P < 0.05). One foot had breakage of the plate and screws at arthrorisis of naviculocuneiform joint and none had complications related to the incision.
CONCLUSIONOperations for Müller-Weiss disease, according to concrete conditions using different therapeutic program, may achieve a satisfactory outcome.

OBJECTIVETo assess the association between leptin gene promoter methylation and serum leptin concentrations in patients with impaired glucose regulation (IGR) and type 2 diabetes mellitus (T2DM).
METHODSMethylation status of leptin gene promoter was determined with methylation-specific polymerase chain reaction. Serum leptin concentrations were determined using enzyme-linked immunosorbent assay.
RESULTSAmong three groups of individuals with different levels of glucose, the methylation rates of leptin gene in IGR and T2DM groups were 43.6 % and 31.5 %, respectively, which were significantly lower than that of healthy subjects (59.2%; Chi-square=22.499 and 5.109, respectively, P<0.05). A lower methylation rate was also observed in T2DM group compared with IGR group (Chi-square=3.962, P<0.05). Leptin levels in both T2DM and IGR groups were elevated compared with normoglycemic subjects, but only T2DM group was significantly higher (q=6.81, P<0.01). Linear regression analysis indicated that serum leptin concentrations has increased along with declining of DNA methylation rate (r=-0.95, P<0.01).
CONCLUSIONLower levels of leptin gene promoter DNA methylation and serum leptin concentrations are associated with the development of diabetes. Measurement of the methylation status of leptin gene promoter and expression can facilitate early intervention of the disease.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.
METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.
RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.
CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

BACKGROUND:Synovial fluid mesenchymal stem cells can be amplified rapidly in vitro and collected by a minimally invasive method. Recent studies have suggested that synovial fluid mesenchymal stem cells have become an important kind of seed cells for bone tissue engineering. Osteogenic differentiation is required to be optimized prior to the application of synovial fluid mesenchymal stem cells in the bone regeneration. OBJECTIVE: To describe a protocol to generate osteoblast-lineage cells from human synovial fluid mesenchymal stem cells of the temporomandibular joint using a cocktail that includes glutamax, dexamethasone, β-glycerophosphate, vitamin C, 1,25-dihydroxyvitamin D3, and to investigate the effect of 1,25-dihydroxyvitamin D3 and dexamethasone on the osteogenic capacity of synovial fluid mesenchymal stem cells. METHODS:Synovial fluid mesenchymal stem cells from the human temporomandibular joint were expanded in vitro and cultured in different osteogenic induction media. The mineralization capacity of osteogenic differentiation was evaluated by alizarin red and Von kossa staining. And the osteogenic markers, including ALP, RUNX2 and OCN, were assessed by reverse transcription-PCR. RESULTS AND CONCLUSION: The mineralization formation increased greatly in the medium with 100 nmol/L dexamethasone and 10 nmol/L 1,25-dihydroxyvitamin D3. The expression of ALP, RUNX2 and OCN was enhanced distinctly in the 1,25-dihydroxyvitamin D3-induced differentiated cells. These findings reveal that appropriate concentration of 1,25-dihydroxyvitamin D3 and dexamethasone can be ideal ingredients to induce the osteogenic differentiation of human synovial fluid mesenchymal stem cells of the temporomandibular joint. Thus, this effective condition can be used to induce the osteogenic differentiation of synovial fluid mesenchymal stem cells for the bone regeneration in the temporomandibular joint.
