Objective To investigate the clinical effects of treatment of chronic pulmonary heart disease (CPHD) at acute stage with sodium ferulate and Ciwujia injection. Methods 90 cases of CPHD at acute stage were recruited into treatment group 1, treatment group 2 and control group. The control group was treated with consistent inhalation of oxygen,antibiotics, and symptomatic therapies like relieving cough, removing sputum, and stopping wheeze. The treatment group 1was treated with sodium ferulate, Ⅳ 0.2g, once daily for successive 14days, in addition to the conventional treatment. The treatment group 2 was treated with Ciwujia Injection, 100ml Ⅳ, once daily for successive 14 days. Observe the curative effect and the changes of blood gas analysis indexes (PAo2, PaCO2, SAO2) and bemorheological indexes (whole blood high-cutting viscosity, whole blood low-cutting viscosity, whole blood recovery viscosity, erythrocyte aggregation index, and HCT) before and after treatment. Result Compared with the control group, both treatment groups got improvement in blood gas analysis indexes and hemorheological indexes and curative effect, but no significant difference between the two groups (P＞0.05).Conclusion both sodium ferulate and Ciwujia injection had good results in treating CPHD at acute stage, and there was no difference between the two medicines in terms of curative effects.

To investigate the possible effects of cyclosporine A(CsA) on the T cell dependent liver injury induced by Concanavalin A (Con A) in Kunming mice,25 Kunming mice were randomly divided into five groups. Con A (doses of 10mg/kg, 20mg/kg and 40mg/kg) was administered via the tail vein to duplicate the liver injury as the ConA group; CsA subcutaneously injected twice at doses of 130mg/kg 15 hours and 1 hour respectively before ConA challenge constitutes the CsA group. Phosphate buffered saline (PBS) only served as the control group. Blood samples for tumor necrosis factor alpha (TNF ?) and alanine aminotransferase (ALT) measurement were obtained at 8 hours after ConA administration. Histopathological examination was also performed for liver tissue. The results showed that ConA induced specific liver injury in Kunming mice was successfully duplicated. CsA markedly protected the mice from Con A induced liver injury by comparing the levels of serum ALT(44?16U/L vs 341?52U/L, P

Objective:To detect the influence of the early Class Ⅲ orthopedic treatment on the development of the maxillary.Methods:Four adolescence rhesus monkeys were fitted with casting Twin-block magnetic appliance(TMA),two were put to death after 1.5 months and another two after 3 months,zygomaticofrontal sutures were harvested,and performed histological examination using optical and electron microscope.Another two monkeys without appliance were served as control.Results:The maxillary sutures were rebuilt,after Class Ⅲ functional orthopedic,and the zygomaticomaxillary suture,zygomaticotemporal suture and transverse palatine suture were especially active.Electron microscopy results showed that osteoblasts and fibroblasts were active,and fibroblasts showed more active effects.Conclusion:During the treatment of the Class III functional orthopedics,maxillary sutures take part in the rebuilding actively,and there are lots of new bone formation along the sutures.

This study was aimed to investigate Baishile Capsule on behavior, memory and expression of SYN I and SYNA in hippocampal CA3 region of depression model rats. SD rats were randomly divided into six groups, which were the control group, depression model group, fluoxetine hydrochloride group, and the Baishile Capsule group (2.88 g·kg-1, 1.44 g·kg-1, 0.72 g·kg-1). The chronic stress depression model rats were established by chronic and mild unpredictable stressors as described in the literature. In the model group, medicine was intragastricly administered once per day and continued for 21 days. In the control group and model group, same volume of distilled water was intragastricly administered. The open-field test, preference for 1% sucrose solution, Morris water maze, and rate of weight were carried out and observed. Immunohistochemistry and in situ hybridization were used in the observation of the expression of SYN I and SYNA in each group of model rats. The results showed that high-dosage Baishile Capsule can significantly increase the horizontal and vertical activities of score after two-week treatment (P< 0.01). The middle-dosage Baishile Capsule can significantly increase the horizontal activity of score after three-week treatment (P< 0.05). The rat's preference for sucrose solution was obviously increased in the high-dosage group after one-week treatment and in the middle-dosage group after three-week treatment (P< 0.01, or P< 0.05). The rate of weight of rats was obviously increased in the high-dosage group after two-week treatment and in the middle-dosage group after three-week treatment (P< 0.01, or P< 0.05). The high-dosage and middle-dosage Baishile Capsule can shorten EL, and significantly increase the number of target quadrant. The high-dosage Baishile Capsule can obviously shorten the target quadrant latency (P< 0.05). Compared with the model group, the immunohistochemistry and in situ hybridization showed high-dosage Baishile can significantly promote the expression of SYN I and SYNA in hippocampal CA3 region; and the middle-dosage group can enhance the expression of SYNA (P < 0.05, or P <0.01). It was concluded that Baishile Capsule can obviously improve the behavior and the expression of SYN I and SYNA in hippocampal CA3 region of depression model rats.

Objective To investigate the influence of three kinds of different Ca~(2+) concentration of dialysate on serum calcium,calcium-phosphorus product,serum PTH and CRP in maintenance hemodialysis patients.Methods 45 patients of maintenance hemodialysis with ages ≥18 years were selected.They were divided randomly three groups,and be given three different kinds of Ca~(2+) concentration of dialysate to carry out hemodialysis with 3 months.Then the patients' variation of blood pressure and whether there were low calcium spasm or ostealgia were abserved during hemodialysis whole range.In addition,changes of their serum calcium、phosphorus、iPTH and CRP at pretherapy and three months after reatment were also detected.Results After three months of hemodialysis,serum iPTH in patients with low Ca~(2+) concentration dialysate increased obviously,and the serum CRP decreased significantly(P0.05),and serum CRP increase notably(P

Objective To study the effect of sodium ?-aescin on the matrix metalloproteinase-9 (MMP-9) and laminin (LN) expression in rats after focal cerebral ischemia and reperfusion, and provide experimental evidence for the relationship of MMP-9 and LN expression change with the neuroprotection of sodium ?-aescin. Methods The Spraque-Dawley (SD) rat model of focal cerebral ischemia and reperfusion of cerebral middle artery was prepared. Fifty-six rats were randomly divided into the normal, sham, ischemia and reperfusion, as well as ischemia and reperfusion-treated with sodium ?-aescin groups. The latter two were further divided into six subgroups according to reperfusion time interval of 3h, 6h, 12h, 24h, 72h and 7d after brain ischemia, with 4 rats in each subgroup. Immunohistochemical staining and image analysis were used to measure the expression of MMP-9 and LN in the ischemic region. Results The expression of MMP-9 started to increase at 6h, reached the peak at 12h, decreased in 24h, and reached the lowest on 7d in cerebral ischemia and reperfusion group. The expression of MMP-9 in the same time groups of the cerebral ischemia and reperfusion-treated with sodium ?-aescin group all obviously decreased (P

Objective To investigate effects of Baishile Capsules on cAMP-CREB-BDNF signal pathway about hippocampal neurogenesis in model rats with chronic unpredicted stress depression. Methods SD rats were randomly divided into blank group, model group, fluoxetine hydrochloride group, and Baishile Capsules high, medium, and low dose groups. Chronic stress depression rat model was established by chronic and mild unpredictable stressors. All groups were given relevant medicine for 21 days. The open-field test, sugar consumption experiment, place navigation test, and space searching experiment were used to detect behavior changes of the rats. ELISA was used to detect content of corticosterone in plasma. The protein expressions of PKA, BDNF, and CREB were detected by immunohistochemical method. Results Compared with model group, Baishile Capsules high dose and medium dose groups could remarkably increase the number of vertical and horizontal activities and 1% sucrose partial eclipse. Platform latency and target quadrant searching time decreased significantly in Baishile Capsules high dose group (P<0.05), and content of corticosterone in plasma increased obviously (P<0.05) in Baishile Capsules all dose groups. Protein expressions of PKA, CREB, and BDNF in hippocampal DG and CA3 area increased significantly (P<0.05) in Baishile Capsules high dose group. Conclusion Baishile Capsules can promote hippocampal neurogenesis through the cAMP-CREB-BDNF signal pathway and realize anti-depression effect.
