The effects of two lipids lowering drugs, Xu Zhiping and Mixtura Dai Huai, on the LDL metabolism by receptor dependent and independent pathways in experimental hypercholesterolemia rats were obsvered using radioisotopic double-labelling trace technique. The results showed that in the receptor dependent or independent pathways, the FCR of LDL was increased by 43% and 34% respectively in Xu Zhiping group, and by 35% and 40% respectively in Mixtura Dai Huai group as compared with controls. Both drugs appeared to be more effective than colifibrate, in promoting clearance of LDL from plasma suggesting that the role in reducing plasma TC and LDL-C was depended on accelerating LDL degradation through both receptor dependent and independent pathways. It was also suggested that immune stimulus in combination with cholagogus may become a new way for prevention of hypercholesterolemia and atherosclerosis.

The effects of Da Huai Mixture on receptor dependent and independent pathways of LDL catabolism of the experimental hypercholesterolemic rats were observed by isotope trace-labelling, measurement of monocytic macrophage function and dot bloting. The results were as follows: (1) Serum total cholesterol was significantly decrcased(P

Objective To survey the clinical effect of combination therapy of Ninggan-Tiaozhong decoction and psychological intervention for chronic atrophic gastritis (CAG).Methods 80 cases CAG were randomly divided into a treatment group (treated with Ninggan-Tiaozhong decoction and psychological intervention) and a control group (treated with Ninggan-Tiaozhong decoction),with 40 cases in each group and performed a therapy for 12 weeks.The clinical efficacy and the change of Symptom Checklist (SCL-90)and Self-Rating Anxiety Scale(SAS) before and after treatment were evaluated.Results After 12 weeks of treatment,the total effective rate was 90.0％ in the treatment group,and 74.4％ in the control group.The treatment group was better than the control group(x2=4.255,P＜0.05).After psychological intervention,SCL-90 and SAS score (39.5±4.3,1.3± 0.6)was significantly reduced in the treatment group than the control group (51.4±3.2,1.5±0.3),(P＜0.05).Conclusion The combination therapy of Ninggan-Tiaozhong decoction and psychological intervention used in CAG is effective to relieve symptoms and to improve life quality of patients.

Objective To investigate the effect of warfarin on the formation of renal calcium oxalate stones induced by 1% ethylence glycol (EG) and 3% ammonium chloride (NH 4Cl) in rats. Methods 30 adult male Wistar rats were randomized to three groups,the control group (A) being non-treated,the stone group (B) rats taken EG and NH 4Cl,and the warfarin group (C) taken warfarin in addition to EG and NH 4Cl.All rats were bred 4 weeks.The renal tissue calcium,the renal calcium oxalate crystallization,and the urinary calcium excretion and serum biochemical data were detected. Results No significant difference has been noted in 3 groups,although there is a tend that number of ranal calcium oxalate crystals in group C was more than that in group B. Conclusions The results denoted that warfarin had no significant effect on the calcium oxalate crystallization in rats.

Objective A easier and faster rat model of organ injury caused by cardiopulmonary bypass was developed to provide a stable and economical experimental platform for the research of CPB ( cardiopulmonary bypass ) .Methods Twenty male Sprague-Dawley rats weight between (288.8 ±26.1)g were randomly divided into sham group and CPB group .The right external jugular vein and bilateral femoral arteries were punctured in sham group ,while the rats in CPB group underwent 60 minutes cardiopulmoanry bypass with the perfusion flow no less than 120 mL· kg-1· min-1 .And the weight ,blood pressure ,blood gas and electrolytes were monitored and analyzed throughout the experi -ment.The serum,lung,liver and kidney were collected at 72 h after the operation for further detection .Results The rat model of cardiopul-monary bypass was established successfully with 90%survival rate .The changes of blood gas during intraoperative and postoperative were in accordance with clinical reality and the injury of lung ,liver and kidney were confirmed by serum results and pathological changes .Conclu-sion The model has the characteristics of lower weight ,less priming solution ,no need for endotracheal intubation and easier to assemble the bypass line ,furthermore the methods of puncture and CPB were exhibited through a large number of pictures .As a consequence ,the difficul-ties of establishing the rat model of CPB were reduced significantly .The changes of pathophysiology during intraoperative and postoperative were similar to clinical realities ,the survival rate and organ injury were satisfactory .So it can be used as an effective tool for the research of organ injury and the evaluation of therapeutic strategies associated with CPB .

Objective: In order to reveal the mechanisms of rh-endostatin and its suppression effect on HUVECs at different activating levels. Methods: Three types of HUVEC were prepared. We detected the ex-pression of CD105 and CD62E on the surface of adhering HUVEC, HUVEC of exponential phase of growth, and HUVEC activated with TNF-alpha. The effect of endostatin on these three types of HUVEC was indicated by the variation in the expression of CD105 and CD62E on the cells. The relationship of the changes in cell markers with the time and the concentration of endostatin was analyzed by SPSS 11.5. Results: The expres-sion of CD105 was correlated with time and dose of endostar in all groups. The expression of CD62E was cor-related with the dose of endostar in HUVEC treated with TNF-α for 24h. Conclusion: Endostatin of a certain dose can inhibit the activation of endothelial cells but it cannot induce cell apoptosis.

OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.
