Objective To investigate the effect of Mahong decoction on serum VEGF and b-FGF of rat model bronchus asthma airway remolding. Method Forty SD rats randomly divided into four groups: blank group, asthma group, hormone group, Chinese medicine group. The asthmatic model was established by sensitization and challenge with ovalbumin, and the rats in the hormone group and Chinese medicine group conferred hormone and Chinese medicine before the challenge. ELISA was used to measure the level of serum VEGF and b-FGF. Results The serum VEGF and b-FGF in asthma group was higher than in other groups (P0.05). Conclusion Mahong decoction may control the level of serum VEGF and b-FGF of rat model of bronchus asthma airway remolding, which has the similar result with hormone.

OBJECTIVE: To investigate the intestinal absorption behaviors of Diospyros kaki L.f. extract (PLE) in self-microemulsifying drug delivery system (SMEDDS). METHODS: The concentration of quercetin, kaempferol and phenol red in rat intestinal perfusion solution was determined by HPLC. Rat single-pass intestinal perfusion technique was employed to assay the effects of concentrations of PLE in perfusion solution, intestinal segments and different formulations on the drug percentage absorbed (P) and the absorption rate constant (Ka). RESULTS: No significant changes of Ka and P were observed in different PLE concentrations. The main absorption segments of SMEDDS in rat intestines were the duodenum and ileum. The values of Ka and P of SMEDDS were significantly higher than the PLE solution (P<0.05). CONCLUSION: The absorption mechanism of PLE conforms to passive diffusion. The PLE SMEDDS presented the high absorption rate than conventional solution in rat intestine, which illustrates the potential use of SMEDDS for the delivery o f PLE by the oral route.

ObjectiveTo study the mechanism of infection-related reactive thrombocytosis.MethodsSeventy-five infectious disease patients were selected including 42 cases with acute infections phase thrombocytosis (acute infectious phase thrombocytosis group),18 cases with acute infectious phase normal platelet count (acute infectious phase normal platelet count group),15 cases with recovered phase (infectious recovered phase group) and 16 cases with healthy controls(control group).The serum thrombopoietin (TPO),intefleukin-6 (IL-6),white blood cell,platelet was determined and compared among 4 groups.Results The serum TPO in acute infectious phase thrombocytosis group [( 159.1 ± 65.9) ng/L]was higher than that in acute infectious phase normal platelet count group,infectious recovered phase group,and control group [(43.5 ± 14.4),(40.3 ± 15.2),(41.8 ± 18.9) ng/L](P＜ 0.05).There was no significant difference in the serum IL-6 between acute infectious phase thrombocytosis group [(542.7 ± 247.0) ng/L]and acute infectious phase normal platelet count group [(598.5 ± 250.4) ng/L] (P ＞ 0.05 ),but which was higher than that in infectious recovered phase group [(43.5 ± 20.7 ) ng/L] and control group [( 38.3 ± 17.6 )ng/L] respectively (P ＜ 0.05 ).The serum IL-6,TPO was positively correlated with platelet,white blood cell.The serum TPO was positively correlated with IL-6.ConclusionElevated TPO leads to the thrombocytosis,which is the possible mechanism of infection-related reactive thrombocytosis.

Lots of studies have identified the relationship between hyperuricemia and cardiovascular diseases. Many factors affect the metabolism of uric acid, such as diet, drug, internal environment of organism, etc. However, the relationship between hyperuricemia and cardiovascular diseases is not quite clear. In this review, we present recently published data about the association between hyperuricemia and selected cardiovascular diseases.

Objective:To explore the clinical value of chest multi-slice computed tomography angiography (MSCTA) as a preoper-ative examination for lung cancer patients undergoing pulmonary lobectomy. Methods: Sixty lung cancer patients formed the study population and were randomly divided into 2 groups of 30 cases each. In the experimental group, CTA images of the tumors and pulmo-nary artery, bronchial artery, pulmonary vein were acquired, analyzed, and post-processed using VR to determine the anatomical rela-tionship between vessels and tumors. Pulmonary lobectomy followed. Cases in the control group underwent pulmonary lobectomy with-out guidance by chest MSCTA. Operation times and amounts of operative blood loss were compared between the two groups. Results:Significant differences between groups in terms of operation time (study group vs. control group, 199±55.7 vs. 231.5±51.2(min);P=0.02) and amount of operative blood loss (study group vs. control group, 318.33±99.6 vs. 431.7±89.5(mL), P<0.01) were observed. Val-ues of operation time and amount of contrast agents in the study group were consistently lower than those in the control group. Conclu-sion:Chest MSCTA can shorten the operation time and reduce the amount of operative blood loss during pulmonary lobectomy. Thus, the technique has significant clinical value.

Objective To explore the diagnosis and treatment of iatrogenic bile duct injury during choledochocystectomy. Methods Clinical data of 24 cases of iatrogenic bile duct injury were analyzed retrospectively from 2005 to 2009. Results Eight patients underwent early repair of bile duct within 4 days after the injury. 14 patients with later recognized bile duct injury underwent selective operations, and two patients were discharged after their jaundice were relieved without any surgical treatment. Supporting T tubes were left in place in 22 patients for 8 to 14 months after operations, without any biliary obstruction found after one year and six months to five year follow-up. Conclusions Early bile duct injury within 4 days was easily treated, but later bile duct injury should have selective operation. The patients with jaundice could be diagnosed with PTCD and ERCP to observe the bile duct injury. During operation membrane-to-membrane wide hepatojejunostomy helps prevent later anastomotic stenosis. The left in drainage tube in anastomotic stoma for more than 8 months improves success rate in the process of injuried bile duct repair.

Objective To observe the effects of electroacupuncture on expression of caspase-3 in the is- chemic penumbra in the early stage of cerebral ischemia in rats. Methods 100 Wistar rats were randomly divid- ed into a sham-operated group, a model group and an electroacupuncture group. The middle cerebral artery was ex- perimentally occluded in the rats in the model and electroacupuncture groups, while a sham operation without cere- bral artery occlusion was carried out on the rats in the sham-operated group. Immunocytochemistry was employed to detect the expression of caspase-3 in the ischemic penumbra at 24 h, 48 h and 72 h after cerebral ischemia. Re- suits There was almost no positive expression of caspase-3 in the sham-operated rats. Numerous caspase 3-posi- tive cells were found in the ischemic penumbra in the model and electroacupuncture groups. The peak of expression was reached 24 hours after cerebral ischemia. The number of caspase 3-positive cells was significantly greater in the model group than in the electroacupuncture group at 24 h and 48 h. Conclusion The increase of caspase 3-posi- tive cells in the ischemic penumbra is time-dependent. Electroacupuncture can significantly decrease the expression of caspase-3.

Objective:To research the clinical effect of abdominal total hysterectomy on the patients with uterine fibroids and the serum vascular endothelial growth factor (VEGF) and interleukin 6 (IL-6),interleukin 8 (IL-8) levels.Methods:106 cases of patients with uterine fibroids from February 2014 to February 2016 were divided into the control group and the research group according to the lottery method,the control group was treated with total abdominal hysterectomy,while the research group was given abdominal total hysterectomy treatment,the operation time,blood loss,anal exhaust time,length of hospital stay,changes of serum VEGF,IL-6,IL-8,Follicle stimulating hormone (FSH),estradiol (E2) levels,resistance to seedling le tube hormone (AMH) before and after the surgery as well as the occurrence of complications were compared between two groups.Results:The operation time,blood loss,length of hospital stay,anal exhaust time of research group were significantly shorter than those of the control group (P＜0.05).Before surgery,the serum levels of VEGF,IL-6,IL-8,FSH,E2,AMH showed no difference between two groups (P＞0.05).After the operation,the serum levels of IL-6,IL-8,E2,AMH of research group were lower than those of the control group (P＜0.05),the serum level of FSH in research group was higher than that of the control group (P＜0.05).The serum level of VEGF showed no difference between the two groups (P＞0.05).The incidence rate of complications in research group was lower than that of the control group (P＜0.05).Conclusion:Abdominal total hysterectomy showed similar effect with the abdominal hysterectomy in the treatment of uterine fibroids patients,but the abdominal full hysterectomy induced less trauma,promoted the recovery of ovarian function after surgery,which might be related to the decrease of serum IL-6,IL-8 and VEGF levels.
