[Objective]To explore the effect of spinal cord injury(SCI) repair by peripheral nerve combined with activitied macrophages graft.[Method]Fistly the preparation of the activated macrophages and fabrication of the peripheral nerve were done.81 BALB/C mice were grouped in A,B,C,D groups randomly after their spinal cord were hemi-resected.20 mice of group A were dealed with activated macrophages graft;20 of group B were dealed with peripheral nerve graft;21 of group C were transplanted both two graftes;20 of group D were contral group.Each of the 4 groups was respectively divided into 3 subgroups randomly.7 of subgroup 1 were investigated by their restoration of the motor function and improvement of the somatosensory evoked potential(SEP).7 of subgroup 2 were tabken for histological examination.The spinal cords were fixed and cut into longitudinal frozen sections,and were immuneostained and stained with hematoxylin and eosin(HE).The numbers of cells or neurofilaments were counted under microscope.6 of subgroup 3(7 of C3)were used as complement ones.All the results were recorded from 1 to 12 weeks postoperative and analyzed statistically using the SPSS 12.0 software package.[Result]The BBB scale and the SEP wave:there was a significant difference between group C1 and the other three groups,there was a significant difference between group A1,B1 and D1,too(ONE WAY ANOVA,P

Objective To study the association of body mass index (BMI) and waist circumference (WC) with dyslipidemia and the risk of dyslipidemia at different BMI and WC level among adults in Suzhou Industrial Park District. Methods A total of 6219 participants were chosen by stratified random cluster sampling method. Four streets were selected form the district first, then one community as a cluster was selected randomly from each street. Questionnaire survey, physical examination and laboratory tests were done by all subjects. Results The prevalence of dyslipidemia was 35.9%;the rates of overweight, obesity and central obesity were 36.6%, 9.6% and 49.5% respectively. The prevalence of dyslipidemia in underweight group, normal weight group, overweight group and obesity group were 13.6%, 30.2%, 47.7%and 59.0% for male, and 17.2%, 27.3%, 38.6%和 48.8% for female respectively. The prevalence of dyslipidemia for male and female both rose with BMI (χ2=139.848, P<0.001; χ2=92.387, P<0.001). The prevalence of dyslipidemia in the high waist circumference group and normal group were 50.2%and 30.9%for male, and 40.8%and 23.8%for female respectively. Prevalence of groups with high waist circumference for male and female were significantly higher than normal groups (χ2=108.669, P<0.001; χ2=110.642, P<0.001). Pearson correlation analysis showed that total cholesterol (TC), triglyceride(TG), and low density lipoprotein cholesterol (LDL-C) were positively correlated with BMI ( r=0.153, P<0.001;r=0.227, P<0.001;r=0.192, P<0.001), and were also positively correlated with WC(r=0.138, P<0.001; r=0.234, P<0.001; r=0.159, P<0.001). High density lipoprotein cholesterol(HDL-C) was negatively correlated with BMI (r=-0.189, P<0.001) and WC (r=-0.185, P<0.001). Logistic regression analysis after age adjustment showed that, compared to the group with BMI<24 kg/m2 and WC<85 cm(male)/WC<85 cm (female), odds ratios (OR) for male in group with BMI<24 kg/m2 and WC≥85 cm, group with BMI≥24 kg/m2 and WC<85 cm and group with BMI≥24.0 kg/m2and WC≥85 cm were 1.602, 1.834 and 3.064 respectively, and ORs for female in group with BMI<24.0 kg/m2 and WC≥80 cm and group with BMI≥24.0 kg/m2 and WC≥80 cm were 1.703 and 2.381 respectively, however, the OR for female in group with BMI≥24.0 kg/m2 and WC<85 cm was not statistically significant (P>0.05). Conclusions BMI, waist circumference and dyslipidemia were closely correlated. Waist circumference is more important than BMI for female.

Objective To investigate the influence of electroacupuncture on the expression of neuropeptides in fibroeartilage callus tissue after femoral fracture. Methods Forty male Wistar rats were randomly divided into a fracture group and an electroacupuncture group. Femoral fracture models were established in both groups, and the rats in the electroacupuncture group were given electroacupuncture. Rats were sacrificed on the 4th, 7th, 14th and 28th days after surgery. The calluses were stained immunohistochemically to detect the expression of calcitonin gene-related peptide (CGRP) and substance P (SP). Results CGRP and SP levels increased rapidly after eleetroacu-puncture, with neuropeptides expressed strongly in callus cell tissue. The optical density (OD) in the electroacu-puncture group was significantly higher than that in the fracture group ( P≤0. 05 ). Conclusion Electroaeupune-ture can significantly increase the expression of neuropeptides in rats after femoral fracture. Electroaeupuneture can promote fracture healing through regulating neuropeptides.

Ferroptosis is a new programmed cell death dependent on iron ions.Ferroptosis can be induced by endogenous or exogenous pathways, and cells exhibit specific cell morphological signs and are regulated by a variety of molecular mechanisms.In recent years, more and more studies have shown that ferroptosis plays an important role in the treatment of cancer.This article summarizes the mechanism of ferroptosis in bladder cancer and the regulation of cancer cells, as well as the role of ferroptosis-related factors, non-coding RNA regulation, N6-methyladenosine (m6A), amino acid metabolism and autophagy dependent ferroptosis in the growth and proliferation of bladder cancer, with a view to provide new strategies for the treatment of bladder cancer.
