Objective:To observe the clinical efficacy of electroacupuncture in the treatment of type 2 diabetes mellitus combined with mild and moderate carpal tunnel syndrome.Methods:Eighty patients with type 2 diabetes mellitus combined with mild to moderate carpal tunnel syndrome were randomly divided into two groups with 40 patients in each group ( n=40). In the course of the treatment, 2 patients in each group dropped out, which means 38 patients in each group were included. All patients were instructed to actively control blood glucose The control group was given Mecobalamin tablets orally, while the treatment group was given electroacupuncture of Daling and Neiguan on the affected side based onthe control group for 6 weeks. The degree of pain was assessed by VAS, and the severity of clinical symptoms was assessed by the symptom scale of Boston carpal tunnel questionnaire (BCTQ). The sensory nerve conduction velocity (SCV), the amplitude of sensory nerve action potential (SNAP) and the distal motor latency (DML) were detected by EMG evoked potential instrument. The clinical efficacy was evaluated and adverse events were recorded. Results:The total effective rate was 81.6% (31/38) in the treatment group and 60.5% (23/38) in the control group, and the difference was statistically significant ( χ2=5.094, P=0.024). After the treatment, the scores of VAS and BCTQ in the treatment group were lower than those of the control group ( t=2.639, 2.790, P=0.010, 0.007); DML (3.62 ± 0.19 ms vs. 4.00 ± 0.17 ms, t=68.891) in the treatment group was lower than that of the control group ( P<0.01), while SCV (47.36 ± 0.18 m/s vs. 42.34 ± 0.14 m/s, t=97.163) and SNAP (14.74 ± 0.18 μV vs. 12.10 ± 0.16 μV, t=51.434) in the treatment group were higher than those of the control group ( P<0.01). During the treatment, no serious adverse events occurred in two groups. Conclusions:Electroacupuncture is safe and effective in the treatment of mild and moderate carpal tunnel syndrome with type 2 diabetes. It can reduce the degree of pain and improve the symptoms of wrist joint.

This study aimed to induce the differentiation of isolated and purified adipose-derived stromal cells (ADSCs) into myoblasts, which may provide a new strategy for tissue engineering in patients with stress urinary incontinence (SUI). ADSCs, isolated and cultured ex vivo, were identified by flow cytometry and induced to differentiate into myoblasts in the presence of an induction solution consisting of DMEM supplemented with 5-azacytidine (5-aza), 5% FBS, and 5% horse serum. Cellular morphology was observed under an inverted microscope. Ultrastructural changes occurring during the differentiation were observed by transmission electron microscopy and confocal laser scanning microscopy. Cellular immunohistochemical staining was applied to determine the expression of desmin protein in cells with and without induced differentiation. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were used to detect mRNA and protein expression, respectively, of sarcomeric and desmin smooth muscle proteins. The results showed that ADSCs were mainly of a spindle or polygon shape. Flow cytometry analysis revealed that ADSCs did not express CD34, CD45, and CD106 but high levels of CD44 and CD90, which confirmed that the cultured cells were indeed ADSCs. After induction with a 5-aza-containing solution, morphological changes in ADSCs, including irregular cell size, were observed. Cells gradually changed from long spindles to polygons and star-shaped cells with microvilli on the cell surface. Many organelles were observed and the cytoplasm was found to contain many mitochondria, rough endoplasmic reticulum (rER), and myofilament-like structures. Cell immunohistochemical staining revealed different levels of desmin expression in each phase of the induction process, with the highest expression level found on day 28 of induction. RT-PCR and Western blot results confirmed significantly higher desmin gene expression in induced cells compared with control cells, but no significant difference between the two groups of cells in sarcomeric protein expression. It was concluded that under specific induction setting, ADSCs can be induced to differentiate into myoblasts, providing a potential new option in stem cell transplantation therapy for SUI.

Objective To investigate the effect of aspirin on endothelin-1 induced proliferation of cardiac fibroblasts (CFs). Methods Isolated and cultured CFs from neonatal Sprague-Dawley rats (SD) were randomly divided into 7 groups: control, ET-1, aspirin, ET-1 +aspirin 1 mmol/L, ET-1 +aspirin 2 mmol/L, ET-1 +aspirin 5 mmol/L and ET-1 + aspirinl 10 mmol/L. CFs were counted by MTr assay. Cell cycle distribution was determined with a flow cy-tometer (FCM). [~3H]-Proline incorporation was evaluated by scintillation counting. Nitric oxide (NO) was meas-ured by colorimetry. Results 10~(-7)mol/L ET-1 significantly increased the number of CFs and [~3H]-Pro incorporation and decreased NO_2~-/NO_3~--secretion compared with the control group (P <0.01).1 ~ 10 mmol/L Aspirin inhibited the effects of ET-1 on CFs in a concentration-dependent manner (P <0.05 vs ET-1). In the ET-1 group, the percent-age of cells in the S phase was higher than that of the control, which was inhibited by 10 mmol/L Aspirin (P <0.01 vs ET-1 and control). Conclusion Aspirin can restrain the proliferation and collagen synthesis of cardiac fibroblasts induced by endothelin-1, and this effect may be partially mediated by NO.
