ObjectiveToevaluatelaparoscopiccholecystectomy(LC)versusopen cholecystectomy (OC) in compensated cirrhotics and model for end-stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP)classification in predicting perioperative morbidity.MethodsBetween January 1998 and June 2011,128 cirrhotic patients of symptomatic innocuous gallbladder disease at CPT class A or B liver function were prospectively and randomly divided into LC group (64 patients) and OC group (64 patients ). Data were analyzed by T test, Mann-Whitney U test and Pearson x2 test.ResultsThere was no statistical differences in operation time between the two groups ( t =1.761,P =0.081 ).The intraoperative blood loss ＞ 200 ml occurred in 15 ( 26％ ) LC patients and 35 ( 55％ ) OC patients ( x2 =4.467,P =0.035 ).LC patients had earlier up and about,earlier oral intake,short hospital stay ( t =5.424,t =8.573,t =15.634; P =0.000,respectively) and lower complication rate [ CTP:24％ (14/58) vs 38％ (24/64),x2 =4.582,P =0.032; MELD scores 21％ (12/58) vs 34％ (22/64),x2 =4.238,P =0.040] compared with OC patients.LC patients' VAS- fatigue and VAS-pain scores on first 3 days were lower than OC according to the VAS (visual analogue scale) (Mann-Whitney U =473.0,MannWhitney =6.0,Mann-Whitney =22.5,Mann-Whitney =24.0,Mann-Whitney =46.0; P =0.000,respectively),and the VRS-cosmetic score was higher in LC group than in the OC group according to the VRS ( verbal rating scale) ( Mann-Whitney =145.0,P =0.000).MELD score ＞ 14 predicted higher blood loss and complication rate regardless of LC or OC,while CPT classification did not seem to predict intraoperative bleeding volume and morbidity.ConclusionsLC can be performed safely in cirrhotic patients with CPT class A and B.LC has less,blood loss lower postoperative complication rate,and quicker postoperative recovery.MELD score system is more valuable than CPT classification system in predicting blood loss and postoperative complication rate in cirrhotics undergoing cholecystectomy.

OBJECTIVETo explore the effect of Shenxiong Huayu Capsule (SHC) on the cerebral ischemia-reperfusion (IR) injury and the expression of growth associated protein 43 (GAP43) after total cerebral IR in the hippocampal CA1 region of rats.

METHODSTotally 100 male adult SD rats were randomly divided into five groups, i.e., the control group, the model group, the group A (by taking SHC once daily), the group B (by taking SHC twice daily), and the group C (by taking SHC thrice daily), 20 in each group. The total IR model was prepared by improved Pulsinelli's 4-vessel occlusion method. Morphological changes of the hippocampal CA1 region were observed by HE staining at day 1, 3, 7, and 14. The expression of GAP43 in the hippocampal CA1 region was detected using immunohistochemical assay at day 1, 3, 7, and 14. Meanwhile, the behavioral score was determined. The expression of GAP43 in the hippocampal CA1 region was detected using Western blot at day 14.

RESULTSCompared with the control group, the expression of GAP43 increased in the model group, the behavioral score was elevated, degenerated neurons increased, and survival neurons decreased in the model group (all P < 0.05). Compared with the model group, the expression of GAP-43 increased (with the most significant difference seen in the group C, P < 0.01), the behavioral score significantly decreased, degenerated neurons decreased, and survival neurons increased in each HSC group (all P < 0.05). Survival neurons obviously increased at day 14, of which, most number of survival neurons and highest contents of GAP43 protein could be seen in the group C, showing statistical difference when compared with those of the group A and the group B (P < 0.01).

CONCLUSIONSHC had protective effect on total cerebral IR in the hippocampal CA1, which might be associated with increased expression of GAP43.

Objective To evaluate the efficacy and safety of methotrexate(MTX)on the hip involve ment in patients with ankylosing spondylitis(AS).Methods Among the AS patients with hip joint involvement admitted to the department from 1999—2002,50 patients were treated with sulfasalazine(SSZ)(control group, CG)and 48 MTX(observation group,OG).One kind of NSAIDs was taken by the patients in both groups as the basic therapy.The treatment was maintained in both groups after being discharged.Patients were followed-up for three years.The observation parameters included symptoms,signs,Bath AS disease activity index(BASDAI), Bath AS functional index(BASFI),hip joint function score,the CT staging of hip joint involvement,serum in- flammation markers,laboratory tests and side effects.The data were analyzed with SPSS10.0 statistics software. Results At the 1st,2nd and 3rd year,44,38 and 32 cases in the OG and 45,38 and 31 cases in the CG were followed up respectively.During the three-year follow-up period,the hip joint function score of the OG was significantly higher than that of the CG(P

Objective The aim of this study was to investigate the radiation dose caused by 18 F-fluorodeoxyglucose (FDG) in PET/CT examination and to optimize the concerned radiation protection. Methods Thirty patients from our conventional PET/CT examination were simple randomly selected, and they all underwent whole body PET/CT imaging. The radioactive dose of injected 18F-FDG was recorded. The internal radiation dose was calculated and the external radiation dose from patients was measured with the 451P-DE-SI ion chamber survey meter. The staff's dose was recorded with thermoluminescent detector (TLD). All dosimetry data were processed and analyzed statistically with Excel 2003. Results The injected radioactive dose of 18F-FDG was (432.9±51.8) MBq, and effective dose equivalent received per patient was (8.23±0.99) roSy. The correlation coefficient (r) of the dose equivalent rate and distance was-0.994 by power function curve fitting, and that of dose equivalent rate and time was - 0.988 by exponential curve fitting. The staff's dose was lower than the annual dose limit. Conclusions The patient's internal radiation dose caused by 18F-FDG in PET/CT examination is low, nonetheless, the clinician should always consider optimizing and minimizing the necessary radiation received by the patients. The patients having been injected with 18F-FDG should stay in one place to decrease their radiation to the public. From the medical point of view in optimizing radiation exposure, there may still be a potential to lower the injected 18F-FDG activity.

OBJECTIVETo observe the protective effects of the Huanglian Jiedu decoction aqueous extract and its active fraction, which consists of total alkaloids, total flavonoids and total iridoid, on the thalamus of cerebral ischemia in rats.

METHODThe rat model of middle cerebral artery occlusion (MCAO) was chosen. Male SD rats were randomly divided into sham-operation group, model group, aqueous extract group (800 mg x kg(-1)), total alkaloids group(44 mg x kg(-1)), total flavonoids group (50 mg x kg(-1)) and the total iridoid group (80 mg x kg(-1)). The rats were administered the appropriate drugs intragastrically once a day, for 7 days after surgery. An equivalent volume of saline was given in the sham surgery and model groups. The HE staining was adopted to observe the pathological changes. Determination of Glu and gamma-GABA in thalamus were detected by HPLC with fluorescence detection. The expression of GAD65 was examined with immunohistochemistry and double staining with uorescent-conjugated antibodies against GFAP and Cx43 was chosen in this study.

RESULTThe neurons degenerated in MCAO rats after cerebral ischemia 7 d. The content of Glu, gamma-GABA decreased (P < 0.05), the expression of GAD65 reduced (P < 0.05) and the expression of GFAP and Cx43 increased (P < 0.01) in thalamus of rats compared with sham-operation group. Huanglian Jiedu decoction aqueous extract, total alkaloids, total flavonoids and total iridoid reduced the degeneration of neurons. Total flavonoids could promote the expression of GAD65 (P < 0.05) and decrease the expression of GFAP and Cx43 (P < 0.01) in thalamus compared with model group while it could also increased the content of Glu,gamma-GA BA to normal levels. Compared with model group, Huanglian Jiedu decoction aqueous extract, total alkaloids and total iridoid could raise the expression of Cx43, and Huanglian Jiedu decoction aqueous extract could also increase the expression of GAD65 (P < 0.05). The expression of GFAP in Huanglian Jiedu decoction aqueous extract group, total alkaloids group and total iridoid group were not different compared with model group while the content of gamma-GABA decreased (P < 0.05) compared with sham-operation group.

CONCLUSIONThe degeneration of nerve cells, the reduction of neurotransmitter amino acids content, the aberrant activation of astrocytes and the abnormal expression of GFAP and Cx43 will appear in thalamus of MCAO rats after ischemia. Huanglian Jiedu decoction total flavonoids could relieve the injury of nerve cell through inhibiting the abnormal activation of astrocytes and regulating the expression of GFAP and GAD65.

Traditional Chinese medicine Curcuma Zedoary ( E'Zhu) contains essential oil, curcuminoid and other effective constituents, with such pharmacological actions as anti-platelet aggregation, lowing blood lipid, anti-oxidation and anti-inflammation. In recent years, studies have showed that certain extracts and chemical components of E'Zhu could mitigate myocardial cell mitochondria injury and protect vascular endothelium by enhancing heme oxygenase-1 activity, inhibit nuclear factor NF-kappaB, target genes interleukin-associated kinase-1 (IRAK-1), tumor necrosis factor receptor-6 (TRAF-6) and vascular cell adhesion molecule-1 (VCAM-1), reduce inflammatory infiltration, and inhibit growth factor-induced smooth muscle cells (SMCs) proliferation and migration by impacting oxidation of cellular phosphatases. Due to its different functions in vascular endothelial cells and smooth muscle cells, E'Zhu has been applied in drug-eluting stents, with a potential effect in preventing in-stent restenosis and thrombogenesis. In this paper, studies on pharmacological effects and mechanisms of extracts and main chemical constituents from E'Zhu in preventing vascular restenosis were summarized.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.
