Methods Plasma homocysteine level was determined in 106 patients with congestive heart failure(CHF).Among them,40 patients were diagnosed as having recent onset of CHF(group 1) and the remaining 66 were receiving conventional treatment(group 2).Thirty healthy subjects were served as a control group. Results(The plasma) homocysteine levels in group 1,group 2 and the control group were(14.87?5.22),(13.25?5.45) and((7.52)?1.73) ?mol/L,respectively.The plasma homocysteine level was significantly higher in group 1 and group 2 than in the control group(P

OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.

METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.

RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

Objective To explore the extent of lung injury induced by hyperoxia,and the activity of ubiquitin-proteasome pathway(UPP) in pathophysiological progress of lung tissue in early stages.Methods Adopted completely random design,20 SD rats were divided into hyperoxia group and air control group.For the air control group,the oxygen concentration exiting the cages was analyzed with oxygen monitor and oxygen concentration remained at 210 mL/L for 72 hours;while in the hyperoxia group,the condition changed into high-density oxygen(950 mL/L) for 72 hours to estimate the hyperoxia lung injury in rats model.The contents linked morphology as pathological classification in gross finding,pathological score of lung injury and the index of pneumonedema-the ratio of moist to dry weight of lungs were mea-sured.The expressions of ubiquitin protein and the activity of proteasome 20 S and the active statement of ubiquitin-proteasome pathway were detected by immunohistochemistry and Western blot methods.Results 1.The hyperoxia lung injury rat model was successfully duplicated.2.In hyperoxia group,pulmonary edema with increased ratio of moist to dry weight of lungs could be found(P=0).3.Macroscopic observation: bright red and full-stacked lung tissue,foliated or local hemorrhage on the surface,but little pleural effusion was observed in hyperoxia group.There was statistical significance of pathological classification in gross finding between hyperoxia group and air control group(P=0.005).Light microscope observation:swelled alveolar epithelium,widened alveoli wall,capillary engorgement and telangiectasis,obvious edema in interstitial tissue of pulmonary aveolus and alveolar space,increased inflammatory cells were observed in hyperoxia group.The findings of pathological score of lung injury indicated more serious injure than control group(P=0).4.The increased expression of ubiquitin protein in lung tissue was discoved by using immunohistochemistry and Western blot findings after hyperoxia exposure 72 hours.(P=0).5.The acti-vity of proteasomes 20 S in hyperoxia group was higher than that in control group(P=0).Conclusions The mainly pathological changes of lung are generated through hyperoxic exposure for 72 hours,including alveolar epithelial cell and vascular endothelial cell injury diffusely,inflammatory cell infiltration and pulmonary edema.Active the ubiquitin-proteasome pathway is connected with the pathophysiological process of lung injury in the initial stages of hyperoxia-exposure.

Objective To investigate the protective effects of the ubiquitin proteasome inhibitor MG-132 on p38 signaling pathway and apoptosis in lung injury induced by hyperoxia. Methods Twenty-six SD rats were randomly divided into 4 groups: normal control group(n=5),MG-132 control group(n=5),hyperoxia group(n=8) and MG-132 hyperoxia group(n=8).Hyperoxia lung injury rat models were established,and proteasome inhibitor(0.5 mg/kg) was intraperitoneally injected in control group and MG-132 hyperoxia group once daily.The resected lungs were histopathologically examined,and cell apoptosis and expression of ubiquitin and p38 were detected by TUNEL and immunohistochemistry,respectively.Results After hyperoxia exposure,there were edema and inflammatory cell infiltration in the lung tissues of SD rats.The apoptosis index and expression of p38MAPK of hyperoxia group were higher than those of normal control group and MG-132 hyperoxia group(P

Pulmonary arterial hypertension (PAH), also named as a cancer of cardiovascular disease, is a rare disease and has complicated pathogenesis. Recently, there are more understandings of PAH pathogeneses. According to the pathogenesis and active pathways, the clinically used drugs are classified into several groups incluidng prostacyclin analogues and prostacyclin receptor agonists, endothelin receptor antagonists, phosphodiesterase-5 inhibitors, soluble guanylate cyclase inhibitors, etc. To elevate the efficacy of the drugs, numerous drug delivery systems are developed. This review mainly summarized the pathological mechanism of PAH, drugs and drug delivery approaches in the treatment of PAH.

OBJECTIVETo analyze the fungal composition in Massa Medicata Fermentata based on culture dependent method and independent PCR-SSCP technique.

METHODFungi were directly isolated from Massa Medicata Fermentata samples. The obtained strains were identified according to morphology and DNA sequence. Meanwhile the total fungal DNA was extracted from Massa Medicata Fermentata samples, the cultural independent PCR-SSCP technique based on β-tubulin gene were used to identify the mycobiota.
