Objective To observe the effects of electro-acupuncture on Jiaji acupoints combine with treadmill training on tibia bone mass of rabbits with sciatic nerve injury,so as to provide the theoretical support for better project to maintain normal metabolism of bone after peripheral nerve injury.Methods A total of 24 New Zealand rabbits were randomly divided into four groups (n =6),namely a model group,a sham group,a treadmill group and an electro-acupuncture + treadmill group according to a random number table.The sciatic nerve of rabbits in the model,treadmill and electro-acupuncture + treadmill group was clamped using hemostatic forceps to establish the model of sciatic nerve injury,while that of the sham group was not clamped,just cut soft tissue around the sciatic nerve.Three days after modeling,the rabbits in treadmill group and the electro-acupuncture + treadmill group were given treadmill training and electro-acupuncture combine with treadmill training respectively,lasting 4 months,whereas those in the sham and the model groups were not given any intervention.Right after modeling,the behavior of rabbits in four groups was observed.Four weeks after treatment or feeding,their bone mineral density and bone strength of tibia were measured.Results Four weeks after treatment,there was significant reduction in bone density and bone strength of tibia in the model,the treadmill and the electro-acupuncture + treadmill groups compared with those in the sham group(P < 0.05) ; the bone mineral density and bone strength of tibia in the electro-acupuncture + treadmill group were 0.17 ± 0.01 g/cm2 and 161.92 ± 43.27 N respectively,significantly higher than those in both the model and the treadmill groups (P < 0.05).Conclusion Electro-acupuncture combined with treadmill training can improve tibia bone mineral density and bone strength after sciatic nerve injury and facilitate the normal metabolism of the bone and to maintain its normal function.

OBJECTIVETo explore the changes in HBsAg titer and HBV DNA load and their correlation in patients with chronic hepatitis B (CHB) and HBV-related liver cirrhosis (HBV-LC).
METHODSForty-six patients with mild to moderate CHB (CHB-LM), 24 patients with severe CHB (CHB-S), and 28 patients with HBV-LC at admission, and 51 patients with HBV-LC at 4.08 ± 3.06 months during antiviral treatment were tested for serum HBsAg titer and HBV DNA load using Abbott chemiluminescence and fluorescence quantitative PCR, respectively.
RESULTSThe serum HBsAg titer and HBV DNA load gradually decreased with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=12.537 and 8.381, respectively, P<0.05). HBsAg titer and HBV DNA load were significantly higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05), but comparable between CHB-LM and CHB-S groups (Z=-0.649 and 0.032, respectively, P>0.05). Among HBeAg-positive patients, HBsAg titer and HBV DNA load tended to decrease with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=6.146, P=0.046 and χ(2)=1.017, P>0.05; respectively), and CHB-LM group had significantly higher HBsAg titer than HBV-LC group (Z=-2.247, P=0.025). Among the HBeAg-negative patients, serum HBsAg and HBV DNA load gradually declined with the disease severity (χ(2)=8.660 and 13.581, respectively, P<0.05), and were obviously higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05). Positive correlations were found between serum HBsAg and HBV DNA levels in CHB-LM (r=0.389, P=0.009) and HBV-LC groups (r=0.431, P=0.022), but not in CHB-S group (r=0.348, P=0.104). After antiviral therapy, the serum HBsAg titer was slightly decreased (Z=-1.050, P=0.294) while HBV DNA load markedly reduced (Z=-5.415, P<0.001), showing no correlation between them (r=0.241, P=0.111) or between the measurements before and after treatment (r=0.257, P=0.085).
CONCLUSIONSerum HBsAg titer and HBV DNA load decreases progressively from CHB-LM to CHB-S and HBV-LC in both HBeAg- positive and -negative patients. The serum HBsAg titer is positively correlated with HBV DNA load, but their levels are not consistently parallel.

Objective To investigate and characterize the serum metabolite profile of patients with rheumatoid arthritis (RA),a common autoimmune disease,which will be of help for early diagnosis in clinic.Methods Serum specimens from 26 patients with RA and 19 age-matched healthy volunteers were collected from the First Affiliated Hospital of Hunan University of Chinese Medicine from January through April 2015.Samples were detected on the gas chromatography-mass spectrometry (GC-MS),and serum metabolites were identified by the chemometric methods.Discriminative model of RA and healthy volunteers was established using partial least squares-linear discriminant analysis (PLS-LDA),and furthermore the established model was evaluated with double cross validation (DCV) for predicting ability.Finally,differential metabolites with clinical diagnostic potential were screened out by using subwindow permutation analysis (SPA).Results The established PLS-LDA discriminative model identified 48 metabolites.The total accuracy of the model approached 97.73%,in which the accuracy of the model for predicting RA and healthy volunteers was 96.15% and 100%,respectively.Our studies screened out 3-hydroxy butyric acid,phosphoric acid,isoleucine,mannose and hexadecanoic acid with clinical diagnostic potential based on the SPA.Conclusions Metabolomics with the application of GC-MS combined with the PLS-LDA method can distinguish patients with RA and healthy volunteers,and can aid in potential early diagnosis of RA.

Solid tumors always exhibit local hypoxia, resulting in the high metastasis and inertness to chemotherapy. Reconstruction of hypoxic tumor microenvironment (TME) is considered a potential therapy compared to directly killing tumor cells. However, the insufficient oxygen delivery to deep tumor and the confronting "Warburg effect" compromise the efficacy of hypoxia alleviation. Herein, we construct a cascade enzyme-powered nanomotor (NM-si), which can simultaneously provide sufficient oxygen in deep tumor and inhibit the aerobic glycolysis to potentiate anti-metastasis in chemotherapy. Catalase (Cat) and glucose oxidase (GOx) are co-adsorbed on our previously reported CAuNCs@HA to form self-propelled nanomotor (NM), with hexokinase-2 (HK-2) siRNA further condensed (NM-si). The persistent production of oxygen bubbles from the cascade enzymatic reaction propels NM-si to move forward autonomously and in a controllable direction along H
