Objective: To investigate the anti-inflammatory, especially the inhibitory effects of TZT-5, an active component from the leaves of Triterygium wilfordii, on the rheumatoid arthritis of rats and to explore its pharmacodynamic effect using an arthritic model of rats. Methods: The ear swelling model induced by croton oil in mice, paw edema model induced by carrageenin in rats, chicken collagen II (CCII)-induced arthritic model, and adjuvant-induced arthritic (AIA) model in rats were established, respectively. The in vivo anti-inflammatory and inhibitory effects of TZT-5 on the rheumatoid arthritis of rats were observed. Results: TZT-5 could alleviate the symptoms of the above four inflammation animal models, ameliorate the infiltration of inflammatory cells in synovium, and inhibit the proliferation of synovial cells in both CCII-induced arthritic models and AIA models of rats. Conclusion: TZT-5 has the ideal anti-inflammatory effects on CCII-induced arthritic model and AIA model of rats and it is a candidate as a new anti-rheumatoid arthritis drug.

Objective: To evaluate the relationship between the change of left ventricular mass and arterial stiffness in the aged patients with diabetes mellitus. Methods: The pulse wave velocity (PWV) and left ventricular mass index(LVMI)were used to estimate the left ventricular mass and arterial stiffness. The relationship between LVMI and PWV and other influencing factors were evaluated with univariate analysis and stepwise regressive analysis in 105 patients with diabetes mellitus. The value of PWV was compared in the subjects of the left ventricular hypertrophy and the non- left ventricular hypertrophy groups. Results: LVMI was positively correlated with PWV, systolic blood pressure, pulse pressure,medical history and body mass index (the values of r were 0.821, 0.792, 0.799, 0.664 and 0.241 respectively,P ＜ 0.01 or P ＜ 0.05). A stepwise regression analysis was used to assess the combined influence of variables on left ventricular hypertrophy. The model included the following variables: PWV, systolic blood pressure and diabetes mellitus medical history. PWV value was significantly higher in patients with left ventricular hypertrophy than that of the patients without left ventricular hypertrophy(t = 9.109,P < 0.01). Conclusion: The increased arterial stiffness is one of the important factors which lead to the increased left ventricular mass index in aged patients with diabetes mellitus.

BACKGROUND:Recently, glucocorticoid-induced necrosis of femoral head has been much studied. However, the precise Wnt signaling pathway by which puerarin suppresses adipogenic differentiation of glucocorticoid-induced bone marrow mesenchymal stem cells adipogenic differentiation of glucocorticoid-induced bone marrow mesenchymal stem cells remains unconfirmed. OBJECTIVE:To investigate the expression of Wnt signaling pathway related genes and the key factor protein,β-catenin, during adipogenic differentiation of glucocorticoid-induced rat bone marrow mesenchymal stem cells treated by puerarin. METHODS:The third generation of bone marrow mesenchymal stem cells were cultured with Dulbecco’s modified Eagle’s medium containing blank serum (blank control group), dexamethasone (hormone group), dexamethasone with puerarin low dose group, the middle dose group and high dose group. After 6 days of culture, in the above five groups, the expressions of Wnt/β-catenin signaling pathway members, Wnt10b mRNA, GSK3βmRNA,β-catenin mRNA, were detected using RT-PCR assay, and the expression ofβ-catenin protein was detected using western blot assay.
RESULTS AND CONCLUSION:Compared with the control group, the Wnt10b mRNA,β-catenin mRNA andβ-catenin protein expressions were significantly higher in puerarin groups, but GSK3βmRNA expression was significantly lower in the puerarin groups. These findings suggest that puerarin effects on inhibition of adipogenic differentiation of glucocorticoid-induced bone marrow mesenchymal stem cells probably are realized through the activation of Wnt/β-catenin signal pathway and regulation of the key factor Wnt10b mRNA, GSK3βmRNA,β-catenin mRNA, andβ-catenin protein expressions. The mechanism by which puerarin prevents glucocorticoid-induced necrosis of femoral head not only improves local microcirculation of the femoral head, but also relates to its inhibitory effects on adipogenic differentiation of glucocorticoid-induced bone marrow mesenchymal stem cells.

Objective To compare postoperative adjuvant chemoradiotherapy with adjuvant chemotherapy in patients with gastric cancer by a meta-analysis.Methods PubMed,EMbase,Cochrane Library,Wanfang,CNKI,VIP,and CBM databases were searched to identify the controlled clinical trials of postoperative adjuvant chemoradiotherapy versus adjuvant chemotherapy for gastric cancer.The obtained data were analyzed using RevMan 5.2.5 and Stata 12.0.The difference between two groups was estimated by calculating the odds ratio (OR) with 95％ confidence interval (CI).Results A total of 12 controlled clinical trials involving 1674 gastric cancer patients,which were selected according to inclusion and exclusion criteria,were included in this meta-analysis.The meta-analysis showed that the 3-and 5-year survival rates were significantly higher in the adjuvant chemoradiotherapy group than in the adjuvant chemotherapy group (OR=2.96,95％ CI=1.75-5.03,P=0.000; OR=1.45,95％ CI=1.06-1.99,P =0.020);the local recurrence rate was significantly lower in the adjuvant chemoradiotherapy group than in the adjuvant chemotherapy group (OR =0.50,95％ CI =0.34-0.72,P =0.000) ; there was no significant difference in distant metastasis rate between the two groups (OR =0.79,95％ CI =0.58 -1.07,P =0.130).Conclusions The meta-analysis of existing study results shows that compared with adjuvant chemotherapy alone,adjuvant chemoradiotherapy is a relatively safe and effective postoperative treatment for gastric cancer.

Objective To research clinical significance of electrocardiogram(ECG) measuring in diagnosis of hyperkalemia. Methods ECG changes and serum potassium concentration from 72 cases have been analyzed and contrasted. Results Forty-one cases with hyperkalemia are detected by ECG changes. Coincidence rate is up to 56.9% with serum potassium test. When the serum potassium concentration exceeds 5.5mmol/L, the accuracy of ECG in diagnosis of hyperkalemia was 22.2%. The main features arc peaked T wave with tabernacle shape ;when the serum potassium concentration exceeds 6.7mmol/L, the accuracy of ECG in diagnosis of hyperkalemia was 74.3%. The main features are ST debased,P wave with low amplitude and time limit increased. Some patients appeared sinus node-ventride conduction. One or two appeared malignant ventricular arrbythmia; when the serum potassium concentration exceeds 10.0mmol/L,the accuracy of ECG was 100% ,most patients appeared malignant ventricular. Conclusion The electrocardiogram measurement has the better consistency with serum potassium test, and abnormal electrocardio-gram will be eccurred,when mixed other electrolyte unbalance. Pseudo-hyperkalemia can be distinguished accurately and conveniently by using this method.

Objective:To observe the effect of breathing andDaoyin exercises on the quality of life in patients with stable chronic obstructive pulmonary disease (COPD) due to deficiency of the lung and kidney (grade II-III).
Methods:A total of 60 eligible cases were randomly allocated into a treatment group (n=30) and a control group (n=30) by random number table. Cases in the control group received routine Western medical treatment, whereas cases in the treatment group conducted breathing andDaoyin exercises in addition to routine Western medical treatment. Patients in both groups were treated for a total of 3 months. Then the observation was made on changes in pulmonary ventilation function, major clinical symptoms, modified Medical Research Council scale (mMRC), distance in 6-minute walk test (6-MWT), COPD assessment test (CAT) and efficacy satisfaction questionnaire for COPD (ESQ-COPD) before and after treatment.
Results:After treatment, the total effective rate was 80.0% in the treatment group, versus 66.7% in the control group, showing a statistical difference (P<0.05). Patients in the treatment group obtained more significant improvement in coughing, sputum production, dyspnea and shortness of breath than those in the control group (P<0.05). Patients in the treatment group obtained more significant elevation in the forced expiratory volume in 1 second percentage of predicted value (FEV1%) and peak expiratory flow rate (PEF%) than those in the control group (P<0.05). Patients in the treatment group obtained lower mMRC score than those in the control group (P<0.05). Patients in the treatment group obtained longer 6-MWT distance than those in the control group (P<0.05). Patients in the treatment group obtained lower CAT score (P<0.01) and higher ESQ-COPD score (P<0.05) than those in the control group.
Conclusion:Breathing andDaoyin exercises combined with routine Western medical treatment are effective for stable COPD (grade II-III) due to deficiency of the lung and kidney and can improve the patients’ quality of life.

Objective To evaluate the characteristics of quantitative monitoring of brain function during the perioperative period in elderly patients and its relationship with postoperative cognitive dysfunction (POCD).Methods Seventy ASA physical status Ⅰ or Ⅱ patients,aged ≥ 60 yr,scheduled for elective lumbar spine decompression and fusion surgery under general anesthesia,having an expected postoperative length of hospital stay ≥ 7 days,were enrolled in the study.The cognitive function was assessed by using Mini-Mental State Examination before operation and the results were normal.Fifty healthy elderly volunteers were chosen and served as control group.Cognitive function was assessed at l day before operation (D0) and 3 (D3) and 7 days after operation (D7).Z score was used to identify POCD.All the patients were then divided into POCD group or control group (group C) according to the results of diagnosis.Quantitative monitoring of brain function was carried out using a traction system,and the wavelet index (WLI),i_22 and i_20 were recorded.Results A total of 67 patients completed the study and were enrolled in the analysis,there were 9 cases in group C,and 58 cases in group POCD.The WLI was significantly decreased at D7,and no significant change was found in WLI at D3 as compared with the value at D0.The WLI was significantly lower at D7 than at D3.There was no significant difference in i_22 and i_20 between the three time points.Compared with group C,i_22 was significantly decreased at D0,and no significant change was found in i_22 at the other time points and in WLI at each time point in POCD group.Conclusion During quantitative monitoring of brain function during the perioperative period in the elderly patients,WLI is significantly decreased on 7th day postoperatively,and no significant change is found in i_20 and i_22,however,the pre-operative low i_22 value can predict the development of POCD.

[ ABSTRACT] AIM:To evaluate the clinical application of single nucleotide polymorphism array ( SNP array) in prenatal diagnosis for screening the abnormality of women with Down’ s syndrome ( DS) .METHODS:The amniotic fluid samples ( n=312) collected by amniocentesis for the DS screening abnormality women were tested by karyotyping and SNP array analysis, respectively.The findings of karyotyping and SNP array analysis were compared.RESULTS:Two cases of trisomy 21 were identified by karyotyping and SNP array analysis, but SNP array analysis failed to identify 6 cases of chro-mosome balanced structural rearrangement.SNP detected 176 cases copy number variants ( CNVs) in 303 cases normal karyotype were detected by SNP, including 106 benign CNVs, 61 variants of unknown significance (VOUS), 9 de novo CNVs, and none of them was pathogenic.The distribution difference of CNVs in DS screening positive group and DS screening positive plus advanced maternal age group was not statistically significant ( P>0.05) .Furthermore, we reported 14 kinds of CNVs for the first time in population.CONCLUSION:SNP array can further assure chromosome microdupli-cation/microdeletion.In normal karyotype fetus of prenatal diagnosis, SNP can detect some clinical significant CNVs.
