Objective To investigate the clinical efficacy of TongluoShu Liquid in treating rheumatoid arthritis at early stage. Methods 100 cases were randomly recruited into a control group and a treatment group with 50 cases in each group. The treatment group was given TongluoShu liquid, 150ml / time, twice a day; and the control group was given Diclofenac Sodium Sustained Release Tablets (Deegan), one granule for each time, twice a day, and Methotrexate 7.5mg / time, once per week. Results In the treatment group, symptoms, signs and biochemical indicators were significantly improved, and the swelling of the soft tissue around the joints in stage Ⅰ and Ⅱ were also reduced. Besides, osteoporosis was controlled and the progress of destruction to the cartilage of stage Ⅲ was detained, though there was no statistical difference between the two groups after the treatment. Conclusion ShuTongluo liquid is a safe and effective medicine with less adverse reactions in treating rheumatoid arthritis.

Objective To investigate the expression of Wnt-5a gene in primary hepatocellular carcinoma (HCC) and to expose its role and clinical significance in the development of HCC.Methods Real time quantitative reverse transcription polymerase chain reaction (RT-PCR) was performed in 26 fresh HCC samples and the corresponding para-carcinoma tissues to detect mRNA expression of Wnt-5a gene.Wnt-5a protein was detected with immunohistochemical method in paraffin embedding tissues of 85 cases of HCCs and the corresponding para-carcinoma tissues,and 15 cases of hepatic cirrhosis.Results RT-PCR analysis showed that Wnt-5a mRNA (0.102 127 ±0.158 620) in the HCC tissues was more than that (0.020 106 ±0.022 075) in the para-carcinoma tissues (P＜0.05).The positive expression rate of Wnt-5a protein in HCC,para-carcinoma,and hepatic cirrhosis tissues were 21.2％ (18/85),81.26％ (69/85),and 86.7％ (13/15),respectively.The positive rate of Wnt-5a was significantly lower in the HCC than in the para-carcinoma and hepatic cirrhosis tissues (P ＜ 0.01).The expression of Wnt-5a was significantly associated with lower tumor node metastasis (TNM) stages and small alpha fetoproteins (AFP) content of blood serum (P ＜0.05).Conclusions The high expression of Wnt-5a mRNA was found in the gene transcription of HCC,while Wnt-5a protein was absent or low in HCC.It was suggested that the roles of Wnt-5a was interfered at the protein level rather than the transcriptional level in the HCC.

This study was aimed to screen main active site to reduce blood lipid from Xin-Mai (XM) capsule and establish HPLC fingerprint of the site, in order to study the correlativity between active site and relevant fractions of its herbs. Solvent extraction was used to separate XM capsule into different polar fractions. Intraperitoneal injection of 75% egg-yolk emulsion was used to establish mice hyperlipidemia models. And the active site was screened. Chromatographic fingerprints of the site and relevant fractions of its herbs were configured by HPLC analysis. The
retention time of peaks was utilized as index to evaluate the correlativity. The results showed that lipid-lowering effect of ethyl acetate extract and garlic essential oil was significant (P<0.01). Fingerprint of the active site in XM capsule was established with 28 fingerprint peaks and the assignment results of 27 peaks were indicated. It was concluded that the active sites to reduce blood lipid of XM capsule were ethyl acetate extract and garlic essential oil. The established fingerprint method can effectively determine the correlativity between the active site and its relevant fractions, which contributed to pharmacodynamic material foundation and quality standard.

This study was aimed to optimize the ethanol extraction technology ofXiao-Xu-Ming (XXM) decoction. The extraction rates of paeoniflorin, ferulic acid, tetrandrine and yield extract were used as comprehensive evaluation indexes. The amount of ethanol, extraction times, extraction time and concentration of ethanol were selected as factors. The orthogonal design was used to optimize ethanol reflux extraction technology of XXM decoction. The results showed that the optimum extraction conditions were as follows: refluxing extracted 3 times with 10 folds, 70% ethanol, 1.5 h for each time. It was concluded that the optimized extraction process was objective, practical, reasonable and stable, which provided experimental basis for industrial production of XXM decoction.

Patients in control group were treated by traction and non-steroidal anti-inflammatory drug for a month, while patients in research group were treated by manipulation combined withTaohong-Siwu decoction for a month. After treatment, the overall efficacy was observed. The Visual analogous scale (VAS) and JOA scores were recorded before and after the treatment. The IL-1β, IL-6 and TNF-α levels of inflammatory factors were detected by enzyme-linked immunosorbent assay.Results The total effective rate of patients in research roup was significantly higher than that of the control group [90.20％ (46/51)vs. 43.14％ (22/51),χ2=19.329, P=0.006]. After treatment, the VAS scores of patients in both groups were significantly decreased, and JOA score increased markedly, which the differences were statistically significant (Ps<0.05). After treatment, the VAS score of research group was significantly lower than the control group (4.26 ± 0.56vs. 5.13 ± 0.87;t=4.843, P=0.027), and JOA score was significantly higher than the control group (18.42 ± 3.92vs.17.33 ± 4.21;t=5.127, P=0.022). After treatment, the IL-1β, IL-6 and TNF-α levels of of patients in the research group were significantly lower than those of the control group (0.57 ± 0.11μg/Lvs. 0.90 ± 0.13μg/L, 112.26 ± 15.17μg/Lvs. 130.38 ± 18.29μg/L, 2.01 ± 0.34μg/Lvs. 2.37 ± 0.51μg/L;t=5.429, 6.317, 5.011,P<0.05). ConclusionsThe Taohong-Siwu decoction combined with manipulation on treatment of the acute phase of LDH was effective. The combined therapy can improve the VAS score and JOA score, and reduce the levels of inflammatory cytokines.

OBJECTIVETo analyze the job burnout and mental health status of clinicians and the relationship of personality with job burnout and psychological stress, and to investigate the direct or indirect effects of personality on psychological stress.

METHODSMaslach Burnout Inventory-General Survey (MBI-GS), Eysenck Personality Questionnaire-Revised Short Scale (EPQ-RSC), and Kessler 10 Scale were administered to 775 clinicians.

RESULTSOf all clinicians, 29.5% had mild burnout, with a score of 22.7 ± 8.18 for psychological stress risk. The effect of personality on emotional exhaustion and cynicism was greater than that on personal accomplishment. Clinicians with a personality of introversion, neuroticism, and psychoticism suffered a higher risk of psychological stress. Personality had both direct and indirect effects on psychological stress. Neuroticism had the strongest effect on psychological stress, with an effect size of 0.55.

CONCLUSIONClinicians have a high level of both job burnout and mental psychological stress risk. Personality is significantly correlated with job burnout and psychological stress risk. Measures depending on personality should be taken for effective intervention.
