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.

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 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.

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 value and limitation of CT in the damage to multiple organs in children with Langerhans cell histiocytosis (LCH). Methods　Analysis of CT manifestations was performed in 13 cases of LCH proved by clinical features, laboratory data, and pathologic changes. Localized LCH was found in 4 cases, and disseminated LCH in 9 cases. All cases were examined by plain scan in craniocerebral, chest, liver, and spleen, and four cases by contrast-enhanced CT scan. Results　The male outnumbered female in this group. Cranial bones were involved in the sequence of temporal bone(8 cases), parietal bone (3 cases), occipital bone (2 cases), and frontal bone (1 case). CT findings were very sensitive in showing the early destructions of the bones. The characteristic manifestation on CT was multiple lytic lesions of the flat bones at any sites, without reactive sclerosis and soft tissue mass accompanied with the bony lesion. Imaging findings presented later than the clinical manifestations for LCH involving the hypothalamus/pituitary axis. Involvement of the lung at various stages by LCH could be demonstrated by CT scan. Conclusion　Imaging manifestations had no characteristics in LCH involvement. The sites of predilection and related CT manifestations could be suggestive of the diagnosis. In addition, CT findings can be helpful in the classification and evaluation of the therapy and prognosis in LCH.
