BACKGROUND:The mechanical index is an important method for the evaluation of the therapeutic efficiency of drug treatment for osteoporosis animal models. OBJECTIVE: To explore the effects of various drug treatments on osteoporosis through a mechanical performance test about the femoral compression of rats. METHODS: Thirty-six Wistar female rats were randomized into six groups: normal control group, model group, Dan Qiparticles group, alpha-D3 group, premarin group, ipriflavone group, with six rats in each group. Osteoporosis models were made in al groups except for the normal control group, and after modeling, the rats in different groups were treated withDan Qi particles, alpha-D3 group, premarin and ipriflavone, respectively. After 15 weeks, the rats were kiled by abdominal aortic bloodletting to take out the left and right femurs that were placed on a universal testing machine to perform a compressive test at a speed of 5 mm/min. RESULTS AND CONCLUSION:The maximum load, maximum stress, maximum displacement, maximum strain, and elastic modulus were significantly lower in the model group than the other four groups (P < 0.05). There was no difference in different mechanical parameters between alpha-D3 group and model group as wel as between Dan Qi particles group and normal control group (P> 0.05). These findings indicate that osteoporosis leads to the variation of compression mechanical properties of the femur. There are good compression mechanical properties of the femur after treatment with premarin and ipriflavone, andDan Qi particles has the best effect.

Pain is one of the common clinical symptom, previous studies have implicated sodium channels as a key constituent in pain signaling. Sodium channel blockers with efficient sodium channel blockade effect play an important role in analgesic treatment. However, most drugs used in clinic have many drawbacks and can not meet the demand of the clinical use. Therefore, for the development of new generation of sodium channel blockers, it is of great significance to find small molecule sodium channel blocking lead compounds with novel chemical scaffolds and new structures, sodium channel blocking activity and structure-activity relationship are discussed in detail, and current problems and trends in future research are also emphasized.

Objective To investigate the clinical efficacy ofHejie Fenxiao Decoction on damp-heat patients with acute kidney injury (AKI).Methods Totally 68 patients were divided into the control group and the treatment group according to the patients’ willings. Both groups were given treatment, such as elimination of the incentives and symptomatic treatment. Besides, patients of the treatment group acceptedHejie Fenxiao Decoction for 30 days. The changes of renal function indexes, such as serum creatinine (SCr), blood urine nitrogen (BUN), uric acid (UA), albumin (ALB) and integral of TCM syndrome, were observed, and recovery ratio and clinical endpoints were compared.Results SCr and eGFR of both group were improved on day 14 (P<0.05). After treatment, the renal function recovery ratio and renal replacement ratio in the two groups showed obvious differences (P<0.05);although survival rate of treatment group was higher than control group, it showed no statistical significance (P>0.05);clinical endpoints analysis of the two groups showed statistical significance (P<0.05). The difference of integrals of TCM syndrome between the two groups showed statistical significance (P<0.05) on day 14.ConclusionHejie Fenxiao Decoction combined with basic regular Western medicine can better improve the clinical symptom, recover the renal function, and decrease the rate of renal replacement and death of AKI damp-heat patients.

Objective To explore the effects and the molecular mechanism of synergistic hepatocarcinogenesis of HBV and AFB1 in the development of HCC by studying the difference in protein expression profiles in hepatocellular carcinoma exposed to hepatitis B virus and Aflatoxin B1.Method 32 HCC specimens were labeled under four categories based on their biomarkers of HBV and AFB1 exposure:group A:HBV(+)/AFB1 (+),10 cases,group B:HBV(+)/AFB1 (-),10 cases,group C:HBV(-)/AFB1(+),6 cases,groupD:HBV(-)/AFB1(-),6 cases.Normal hepatic tissues from 10 cases of hepatic hemangioma,liver resection and liver transplant donor were chosen as the normal control group.Isobaric Tagging Reagent Quantitative (iTRAQ) Proteomics together with 2DLC MS/MS were applied to analyze the differentially expressed proteins among the 4 groups.Result (1) A total of 117 unique differentially expressed proteins including 53 up-regulated proteins and 64 down-regulated proteins were identified in the four groups.The number of unique differentially expressed proteins,including up-regulated and down-regulated proteins,in group A,group B,group C and group D were 106,97,104 and 74 respectively.(2) Among the 117 differentially expressed proteins,9 proteins were heat shock proteins or chaperones,and they were up regulated in group A,B and C.Besides,15 proteins were detoxification and drug metabolism pathway related proteins,12 of them were down-regulated in group A,and more than half of them were also down-regulated in group B and C.(3) The Reverse Transcriptase PCR result showed the mean expression level of AKR1B10 mRNA in group A was significantly higher than group B,C and D (all P＜0.05,respectively).Group C also showed significantly a higher expression level of AKR1B10 mRNA than group D (P＜0.05).The Western-blot results showed the mean expression level of AKR1B10 protein in group A was significantly higher than group B and D (all P＜0.05,respectively).Conclusions The up-regulated expression of heat shock protein and the down-regulated expression of most protein enzymes related to detoxification and drug metabolism were the common molecular biological events of HCC associated with exposure to HBV and AFB1.This suggested the synergistic hepatocarcinogenesis effects of HBV and AFB1 may be related to dysregulation of protein enzymes related to detoxification and drug metabolism.The overexpression of AKR1B10 may be involved in the AFB1-related hepatocarcinogenesis process.
