Objective: To evaluate the clinical characteristics of Chinese patients with distal hereditary motor neuropathy (dHMN). Methods: The clinical data on patients with dHMN collected from literatures published in China and from the patients treated in our hospital were retrospectively analyzed. Results: The male to female ratio of patients was 1.32 : 1. The age of onset was from 13 to 60 years old, with a mean of (38.2±10.4) years old. The incidences of onset from the lower limbs, the upper limbs, and the four limbs were 84.7% 5.6%, and 9.7%, respectively. The incidences of decreased tendon reflexes, lost tendon reflexes in the upper limbs, decreased tendon reflexes and lost tendon reflexes in the upper limbs were 30.4% 65.3%, 13.0%, and 87.0%, respectively. The incidences of grade 3-4, grade 2, and grade 0-1 muscle strength of the upper limbs, grade 3-4, grade 2, and grade 0-1 muscle strength of the lower limbs were 55.4%, 37.5%, 7.1%, 50.0%, 37.5%, and 12.5%, respectively. No sensory disturbance was found in the patients. Electromyography (EMG) of 26 patients showed neurogenic damages; the motor and sensory nerve conduction velocities were all normal. Eight patients showed neurogenic amyotrophy in muscular biopsy. Conclusion: The onset of dHMN is mainly at middle-age and mainly in the lower limbs. The major manifestations include weakness and atrophy of distal limb muscles, decreased or lost tendon reflexes without sensory loss. Electrophysiology and pathology examinations play an important role in the diagnosis of dHMN.

Objective To investigate the impact of human adipose-derived stem cells(hASCs) -plastelet-rich plasma(PRP) composite on the wound healing of radiation skin injury of nude mice.Methods ASCs were isolated from healthy adults after liposuction, conducted primary culture and subculture.PRP was prepared by two-step ultracentrifugation.The ASCs-PRP composite was prepared with ASCs (1 ×107cells/ml) at passage 6 and PRP.Twenty-four nude mice were randomly divided into 4 groups (n=6).A round shaped full-thickness skin defect (D=1cm) was made on the mice back after 20Gy (60Co) round shaped exposure (D=2cm).Right after radiation, wounds were treated as follows,in group A,there was ASCs+PRP, in group B, PRP,in group C, ASCs,in group D, sham group.The wounds were observed at postoperative 7 and 14 days.HE and CD31 stain were observed at 14th days after surgery.Results The wound healing of group A healed completely at 14th days.In group D,the wound healing were slowest and still filled with granulation tissue at 14th days.The wound healing of group B and group C were faster than that of group D, but they haven′t healed completely at 14th days.The inflammatory cells were significantly lower and the blood vessel density positive rate were significantly higher in ACSs+PRP group than in ACSs group,PRP group and sham group (P<0.05).Conclusion ASCs-PRP Composite can accelerate the wound healing of radiation skin injury by promoting wound angiogenesis.

Objective\ By inhibiting approach of apoptosis of T cells to observe if it could reduce the attacks of tumor cells upon lymphocytes and its possible role in tumor treatment. Methods\ The expressions of Fas/FasL genes in ovarian carcinoma cells were detected by using flow cytometry and RT\|PCR method.The construction of pcDNA3\|antisense Fas,the constructed vector was transfected into Jurkat cells with lipofectin,the change in expression of Fas gene was determined by flow cytometry.By means of Annexin\|V and MTT the effect of apoptosis in transduced Jurkat cells was investigated,and also using MTT cytotoxic test to investigate how 3AO cells kill Jurkat cells. Results\ Fas/FasL were expressed in 6 ovarian carcinomal cells.The expression level of Fas protein in Jurkat cells transduced with the constructed vector was decreased.Apoptosis was reduced in antisense Fas\|transfected Jurkat cells after anti\|Fas treatment. Conclusion\ FasL expression in ovarian carcinoma may be one of the reasons for ovarian carcinoma to escape immunosurveillance and attacking lymphocytes.Blocking Fas expression in lymphocytes can partially inhibit Jurkat cells apoptosis induced by anti\|Fas and reducing the attacks of tumor cells upon lymphocyte.\;

OBJECTIVETo assess the clinical outcomes of balloon kyphoplasty assisted with calcium phosphate cement (CPC) in treating osteoporotic vertebral fractures (OVF).

METHODSFrom January 2009 to January 2011, 26 patients with osteoporotic vertebral fractures were treated with balloon kyphoplasty assisted with CPC, including 31 vertebrae. There were 15 males and 11 females with an average age of (71.67 +/- 4.36) years old (ranged from 60 to 89 years). Course of disease was from 0.5 to 7 days with an average of 3.2 days. Clinical outcomes were assessed by the visual analogue scale (VAS) and the oswestry disability index (ODI). Vertebral height loss and kyphotic angle were measured by X-rays.

RESULTSAll patients were followed up for 10 to 24 months with an average of 18 months. Before operation, 24 hours after operation and at final follow-up, VAS scores were 7.91 +/- 1.20, 3.22 +/- 1.12, 1.92 +/- 0.83, respectively; ODI scores were 40.00 +/- 1.15, 17.00 +/- 2.12, 13.00 +/- 1.42, respectivesly; vertebral heights were (18.21 +/- 3.21), (23.82 +/- 3.10), (21.85 +/- 3.24) mm, respectivesly; vertebral kyphosis angles were (18.21 +/- 3.21) degrees, (7.42 +/- 3.13) degrees, (10.01 +/- 3.11) degrees, respectivesly. There was significant difference between preoperation and 24 hours after operation, and between final follow-up and preoperation (P < 0.05). There was no significant difference between final follow-up and 24 hours after operation (P > 0.05).

CONCLUSIONBalloon kyphoplasty assisted with calcium phosphate cement (CPC) is effective for the treatment of osteoporotic vertebral fractures (OVF), which can expeditiously relieve pain and effectively rebuild height of vertebral body and kyphotic angle, and also has advantages of minimal trauma and good security.

This is to report the study of degradation of earthworm extracts prepared by wet superfine grinding in simulated gastrointestinal environment. Enzymatic reactions were terminated by adjusting the solution pH or using membrane bioreactor principle. Earthworm protein concentration change was detected by Bradford method, the degraded state of protein was described with SDS-PAGE technology, and the degraded state of small molecule substances was detected by HPLC. The results showed that earthworm protein degraded completely in artificial gastric juice. High molecular weight protein degraded greatly in artificial intestinal fluid, while low molecular weight protein was not significantly degraded. Small molecular substances degradation did not degrade in artificial gastric juice, while they degraded obviously in artificial intestinal fluid, there is even new small molecule substance appeared. Finally it is concluded that the substance that having therapeutic effects in vivo may be some degraded peptide, amino acid and stable small molecules existed in artificial intestinal fluid.

Objective To explore the methylation status of Rap1 GTPase activating protein (Rap1GAP) promoter in colon cancer, and to provide the oretical basis and research direction for the early diagnosis, targeted therapy, anti-multidrug resistance of colon cancer and so on. Methods The paraffin embedded specimens of 33 patients with colonic adenocarcinoma diagnosed by pathology were analyzed from Department of Pathology of Xinzhou City People′s Hospital from January 2010 to September 2014, including 19 males and 14 females, and aged 41-72 years old. The paraffin embedded specimens of 16 patients with colonic adenoma were enrolled, including 9 males and 7 females, and aged 34-58 years old. 13 normal tissues from the tumor distal margin (from the tumor > 15 cm) were selected. Quantitative methylation specific PCR (q-MSP) was applied to detect methylation level of Rap1GAP gene promoter. The methylation level differences of Rap1GAP gene promoter region among 3 groups or between different clinicopathologic factor subgroups were compared. Results The methylation rates [median (interquartile range)] of Rap1GAP promoter were 65.43 % (50.35 %), 21.37 % (8.39 %) and 17.43 % (15.71 %) in colonic adenocarcinoma group, colonic adenoma group and adjacent normal tissue group, respectively. The methylation rate of colonic adenocarcinoma group was significantly higher than that of colon adenoma group or that of adjacent normal tissue group (P< 0.05). The methylation rates of Rap1GAP promoter in colonic adenocarcinoma were not correlation with age, sex, differentiation and the stage of TNM [ male vs. female: 42.74 % (70.44 %) vs. 21.98%(80.00%);≤60yearsoldvs.>60yearsold:36.26%(62.62%)and26.23%(76.42 %);well-differentiated vs. moderately/poorly-differentiated: 21.98 % (40.32 %) vs. 42.74 % (74.20 %); TNM Ⅰ-Ⅱ vsⅢ-Ⅳ: 25.31 % (48.27 %) vs. 36.26 % (75.55 %); all P> 0.05]. Conclusion The methylation status of RAP1GAP promoter maybe associate with genesis and development of colon cancer, which might be used as a target for early diagnose of colon cancer.
