Objective To establish a rat model of pulmonary hypertension induced by left-to-right shunt and explore the influence of high pulmonary blood flow on pulmonary vascular collagen remodeling.Methods Abdominal aorta and inferior vena cava shunting was produced in rats. Pulmonary artery meanpressure (PAMP) of each rat was measured by using a right cardiac catheterization.Pulmonary artery collagen Ⅰ and Ⅲ were detected using immunohistochemisty.Results After 11 weeks of shunting the Qp/Qs was 3.3∶1.0,indicating a large shunt. Pulmonary artery mean pressure was increased as compared with controls[(23.0?0.9) mm Hg vs (15.7? 1.1) mm Hg,P

A cardiac stimulator for rapid atrial pacing animal model was designed in this paper. According to the needs of clinical research, output pulse parameters of the cardiac stimulator can be designed. The cardiac stimulator will be controlled through magnet. Efficiency of the cardiac stimulator was validated by animal experiments.

Background Oxidative stress-induced apoptosis of human lens epithelial cells (LECs) is associated with c-Jun N terminal kinase (JNK) pathway.Quercetin possesses the antioxidation by inhibiting the JNK pathway.However,whether quercetin can protect LECs from the oxygen-induced damage is still not proved.Objective This study attempted to invatigate the effects and its mechanism of quercetin against hyperbaric oxygeninduced LECs apoptosis. Methods Human LECs line SRA01/04 was cultivated and passaged in MEM medium containing 10% fetal bovine serum and 0.5% non-essential amino acids for 2 hours,with or without 20 μmol/LSP600125 or 1 μmol/L quercetin prior to exposure to hyperbaric oxygen.Each exposure session remained 6 hours in 99% O2 and 1%CO2 with a pressure chamber at 588 kPa.The viability of human LECs was detected by MTT.Cell apoptosis was assessed by flow cytometer using Annexin V-FITC apoptosis detection.The expression of JNK/p-JNK,c-Jun/p-c-Jun,caspase 3 and caspase 9 were detected by Western blot. Results LECs viability (A570 ) was 0.835 ±0.082,0.450±0.083,0.654±0.079,0.649±0.090 respectively in the blank control group,hyperbaric oxygen exposed group,hyperbaric oxygen+SP600125 group and hyperbaric oxygen+quercetin group.The A570 in the hyperbaric oxygen exposed group was significantly lower than the blank control group ( P =0.000),but those in hyperbaric oxygen + SP600125 group and hyperbaric oxygen+quercetin group were significantly higher than the hyperbaric oxygen exposed group ( P =0.003,0.002 ).The numbers of apoptosis cells were 3.17 ±0.74,19.77 ± 1.44,8.45 ±0.93,7.79 ±0.78 respectively in the blank control group,hyperbaric oxygen exposed group,hyperbaric oxygen+SP600125 group and hyperbaric oxygen+quercetin group.Apoptotic LECs were significantly increased in the hyperbaric oxygen exposed group compared with the blank control group ( P=0.000),but those in the hyperbaric oxygen+SP600125 group and hyperbaric oxygen+quercetin group were significantly reduced in comparison with hyperbaric oxygen exposed group (both P=0.000).In additional,expressions of p-JNK,p-c-Jun,caspase 3 and caspase 9 proteins in the cells were elevated in the hyperbaric oxygen exposed group compared with the blank control group (all P =0.000 ),however,those in the hyperbaric oxygen + SP600125 group and hyperbaric oxygen + quercetin group were declined when compared with the hyperbaric oxygen exposed group( all P<0.05 ). Conclusions JNK pathway is involved in the apoptotic procedure of human LECs induced by oxygen stress.SP600125 and certain concentration of quercetin can interdict the JNK signal pathway and endogenous apoptosis of LECs and further alleviate hyperbaric oxygen-induced damage of LECs.

To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety.

ObjectiveTo study the effects of the Behavior Therapy on outpatient with schizophrenics in relieving symptoms, insight, and attitude to treatment. Methods96 outpatients with schizophrenia were randomly assigned to the Behavior Therapy group and the control group. The Behavior Therapy courses were given to the Behavior Therapy group for six months. All the subjects were evaluated with Positive and Negative Syndrome Scale(PANSS) and Insight and Therapeutic Attitude questionaire(ITAQ). Results94 cases completed the trial. The scores of PANSS, the Negative Subscale, the General Psychopathology Subscale of the Behavior Therapy group decreased significantly after treatment(P<0.01). The score of ITAQ of the Behavior Therapy group increased significantly after treatment(P<0.01).The reductions of PANSS, the Positive Subscale, the Negative Subscale, the General Psychopathology Subscale and ITAQ between two groups were significant different(P<0.05-P<0.01). Conclusions The Behavior Therapy may play an important role in augmenting optimal pharmacotherapy for outpatients with schizophrenia and it is effective in improving symptoms, insight and therapeutic attitude.
