Objective To investigate the relieving effect of acupuncture plus medication on persistent right upper abdominal and scapular pains during acute exacerbation of chronic cholecystitis.Method One hundred patients with acute exacerbation of chronic cholecystitis were randomly allocated to treatment and control groups, 50 cases each. The control group received medication and the treatment group, acupuncture at points Yanglingquan, Dannang and Taichong in addition. Both groups were treated once daily, for a total of seven days. Liver function indicators (alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), total bilirubin (TBIL) and direct bilirubin (DBIL)) were measured and the VAS score was recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the three groups.Result There were statistically significant pre-/post-treatment differences in the liver function indicators and the VAS score in the three groups (P<0.05). There were statistically significant post-treatment differences in TBIL and DBIL, and the VAS score between the treatment and control groups (P<0.05). The total efficacy rate was 98% in the treatment group and 50% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture plus medication can effectively relieve the pain induced by acute exacerbation of chronic cholecystitis and improve the liver function indicators in the patients.

Objective To investigate the effects of the 2,3,4′,5-Tetrahydroxystilbene -2-O-beta-D-glucoside on the prolif-eration of PASMCs induced by hypoxia , in orde to search new drugs for the treatment and prevention of hypoxic pulmonary vascular remod -eling.Methods 3%O2 hypoxia was used to induced the proliferation of PASMCs .After hypoxic and TSG treatment for 24h, cell growth was determined by cell counting kit -8 ( CCK-8 ) , cell cycle was analysed by flow cytometry , the mRNA expression of HIF -1αwas measured by quantitative real -time PCR, and the reactive oxygen species ( ROS) production was determined by the fluorescence micro-plate reader .Results TSG can block the proliferation of PASMCs through G 0/G1 to S phase of the cell cycle arrest without cell cytotoxic-ity.Further experiments showed that TSG blocking the proliferation of PASMCs was associated suppression the mRNA expression of HIF -1αand the production of intracellular ROS in hypoxia -stimulated-PASMCs.Conclusion TSG can inhibit the proliferation of pulmo-nary artery smooth muscle cells induced by hypoxia through suppression the mRNA expression of HIF -1αand the production of intracel-lular ROS.

AIM:To study the effect of levofloxacin(LVFX)on serum concentrations and pharmacokinetics of phenytoin sodium(PHT)in rabbits.METHODS:Using UV-spectrophotometry,the serum concentrations of PHT were determined in nine rabbits before oral feeding LVFS and after a single dose of PHT given iv 10 days later.The pharmacokinetic parameters were worked out with 3p87 program.RESULTS:The concentration-time curve of PHT was fit to open two-compartment model.After co-administration of LVFX,the serum concentrations of PHT were decreased to some extent and part of pharmacokinetic parameters obviously changed as well.CONCLUSION:Co-administration of PHT and LVFX will accelerate the metabolic process of PHT.

AIM: To compare the effect of s. miltiorrhize bunge injection (SMBI) and s. przewalsii maxim injection (SPMI) on acute focal cerebral ischemia in rats, and to study the mechanism of the actions of two agents. METHODS: Acute focal cerebral ischemia model was made by middle cerebral artery occlusion (MCAO) in rats, and cerebral infarction volume was determined quantitatively by computer microscopical image analysis instruments. MDA content in serum was determined by TBA colorimetric analysis. SOD content in serum was studied by radioimmunity method. The scavenging effect of hydroxyl radical (?OH) was measured by electron spin resonance technique (ESR). RESULTS: SMBI and SPMI could markedly reduce infarction volume after occlusion of middle cerebral artery and MDA content in serum in rats. SMBI could elevate SOD content in serum. Two injections could markedly inhibit the formation of hydroxyl radical (?OH),and the effect of SPMI was better than that of SMBI. CONCLUSION: The effects of both SMBI and SPMI are similar, and it is possible that SPMI as a satisfactory substitute for SMBI.

Objective To comparative analyze the CT enhanced scan and digital substraction angiography (DSA) in showing the residual and new lesions after treatment of transcatheter arterial chemoembolization (TACE).Methods 60 cases of patients with complete clinical information and imaging data from June 2010 to February 2013 were collected,these patients were diagnosed of primary hepatocelluar carcinoma and underwent TACE treatment.The sensitivity and specificity of CT and DSA to detect the residual and new lesions after TACE treatment were analyzed.By analysis of the main factors affecting the low detection rate to seek a method that can improve PHC residual new lesions detection rate after TACE.Results There were 86 lesions in 60 cases,CT enhanced scan clearly determined the diagnosis of 49 lesions (42 residues,7 new lesions).37 lesions did not prompted to tumor recurrence (residual and new lesions).DSA as the gold standard,the sensitivity of CT enhanced scan to check out the lesions was 84.5 ％ (49/58),specificity was 100.0 ％ (28/28),the false negative rate was 15.5 ％ (9/58),the accuracy was 89.5 ％ (77/86).Enhanced CT detection rate of tumor recurrence was 57.0 ％ (49/86),the DSA detection rate of tumor recurrence was 67.4 ％ (58/86).The difference of determining tumor recurrence between the CT enhanced scan and DSA was significant (x2 =7.11,P ＜ 0.05).Conclusions Three dynamic contrast-enhanced CT scan is the first choice for follow-up examination methods after TACE for hepatocellular carcinoma,but many factors will affect the detection rate of the residual and new lesions.Compared with CT examination,DSA examination has more advantages.DSA examination should be performed when the clinical suspicion of tumor recurrence is negative after enhanced CT scan.

Patients with ischemic stroke is often accompanied by inflammtory response. Studies have suggested that toll-like receptor 4 (TLR4) has induced the occurrence,development and of ischemic stroke and secondary brain injury. This article reviews the toil-like receptor 4 signal transduction pathway and its roles in ischemic stroke in order to provide certain basis for the development of TLR4-targeted medication.

Objective To investigate the production of IL-17,IL-4 and IFN-γ in sputum of pediatric patients with asthma.Methods 61 pediatric patients with asthma in stage of exacerbation were enrolled as exacerbation group.and these patients in remission stage after therapy were enrolled as remission group, and 45 healthy children were chose as control group.The percentage of neutrophils and eosinophils were counted in regular way with sputum pigmentation,and the level of IL-17,IL-4 and IFN-γ were detected by enzyme-linked immunosorbent assay.Results IL-17 in exacerbation group Was highest among three groups, and IL-17 in remission group was higher than that in control group.In exacerbation group,IL-4 was higher and IFN-γ was lower than those in other two groups,and no significant difference Was found between remission group and control group.While in exacerbation stage,IL-17 was positive correlated with IL-4,and IFN-γ was negative correlated with IL-17 and IL-4.Conclusions IL-17 and IL-4 are related to the occurrence and exasperating of asthma,and IL-17 is suit for indicating the inflammation of asthma.IFN-γ is a protective factor of asthma.

Objective To study the distribution of As and other trace elements in drinking water,grain and soil of arsenism disease area in Tumotezuoqi of Inner-Mongloia and to provide theoretical bases for the prevention and treatment of endemic arsenism and improving water quality.Methods The concentrations of As and other trace elements in well-water,wheat,corn,sorghum and soil were determined using neutron activation analysis.Results The result showed that the arsenic contents in drinking water of Tumotezuoqi were from139to899?g /L,which were much higher than that of the allowance limit(

Objective To evaluate the use of the kite flap (als o known as subcutaneous pedicled V-Y advancement flap)for the repair of moderate -sized anterior lamellar skin defects of eyelid. Methods Since 1994, kite flaps have been used to repair anterior lamellar skin defects of eyelids in 14 patients. Six patients were male and eight female, with a mean age of 43 years (range 15-64 years). The diameter of the largest defect reache d 1/3 length of the eyelid. The flaps were designed adjacent to the defects and the incision line corresponding to natural winkle lines on the eyelid. We underm ined the flap under the orbicular muscle, and advanced the flap to cover the def ect. The incisions were closed with 7-0 suture. Results After operation, all flaps survived with primary healing. Follow-up for 3 to 12 months showed that all cases had achieved satisfactory cosmetic effects without secondary deformity. Conclusions It is a simple, safe, an d reliable method to use kite flap for the repair of moderate-sized anterior la mellar eyelid skin defects that are too large to achieve primary approximation. Because kite-flap covers the defect through a direct advancement way without ro tation and twist, there are no dog-ear deformitys present at the pedical area a nd the repaired area looks smoothly. Because of its widely based muscle pedicle which incorporates venous and lymphatic drainage over most of its length, the un desirable pigment deposition is avoided.

Objective To evaluate the effect of vascular endothelial growth factor (VEGF) expression on varicose recurrence in esophagus after devascularization in portal hypertensive rats. Methods Murine pre-hepatic portal hypertension (PHPH) was induced by partial portal vein stenosis. 3 weeks after the establishment of the PHPH, all rats including sham operation group (SO) underwent devascularization. Esophagus was sampled at the time of 1, 3, 5, 7, 14, 30, 90 days after devascularization respectively. The expression of VEGF and factor Ⅷ related antigen (FⅧAg) was detected by immunohistochemistry,and the microvessel density (MVD) was counted under FⅧAg staining. ResultsCompared to the SO rats, the MVD of esophagus in PHPH rats increased significantly before devascularization(P0.05). At the third month after devascularization, the MVD of PHPH rats was higher than that of SO rats. In SO rats, MVD increased after devascularization, reaching the peak on the third day and then levelling off.The expression of VEGF before devascularization in PHPH rats was significantly higher than in SO rats, and VEGF experssion was on the pinnacle in two groups after devascularization, but the expression time of PHPH rats was significantly longer than SO rats(P
