OBJECTIVETo observe analgesic effect and safety of acupuncture compound anesthesia in transvaginal ultrasound-guided oocyte retrieval.

METHODSThree hundred and sixteen cases undergoing in vitro fertilization and embryo transfer (IVF-ET) were randomly allocated to an acupuncture compound anesthesia group (n = 146) and a simple Pethidine group (n = 170). They received respectively electroacupuncture combined with intramuscular injection of Pethidine and simple intramuscular injection of Pethidine 30 min before oocyte retrieval.

RESULTSThe acupuncture compound anesthesia group was significantly better than the simple Pethidine group in the pain rating and pain score (P < 0.01); the incidence rate of abdominal pain at 1 h and 2-5 h after oocyte retrieval in the acupuncture compound anesthesia group was lower than that in the simple Pethidine group (P < 0.01).

CONCLUSIONIn transvaginal ultrasound-guided oocyte retrieval, acupuncture compound anesthesia has the advances of safety, high effectiveness, rapid recovery after oocyte retrieval, and few side effects.

OBJECTIVETo investigate characteristics of treating dislocation and fracture of sacroiliac joint through anterior and posterior approaches.

METHODSBetween January 2006 and September 2012, 39 patients with dislocations and fractures of sacroiliac joint were treated with operation. There were 28 males and 11 females, aged 12 to 64 (mean, 41.3) years old. Seventeen cases were chosen through anterior approach, 13 cases through posterior and 9 cases were combined with anterior and posterior approaches. The anterior approach were made with supine position, performed open reduction, and two plates with 4 holes were used as internal fixation for arthrodesis of sacroiliac joint after reduction; while posterior approach prone position, close or open reduction was performed, and one or two partial thread lag screws, which with 7.3 mm in diameter and 60 to 75 mm in length, were penetrated via sacroiliac joint for fixation under X-ray. Postoperative complications were observed, Matta and Majeed scoring were used to evaluated currative effects.

RESULTSAll patients were followed up from 6 to 36 months. The patient could sit on the bed 2 to 4 weeks after surgery and walk with a crane 6 weeks' later. No breakage or loosening of screw occurred during follow-up. In all but one case with old sacral iliac fractures reducted poor, others obtained good opposition. According to Matta's criteria, 30 cases got excellent results, 8 good and 1 fair. According to Majeed's funtional standard, 14 patients got excellent results, 20 good 4 fair and 1 poor.

CONCLUSIONTreating dislocation and fracture of sacroiliac joint through anterior and posterior approaches can obtain good effects. However, anatomic location, fracture types, degree of displacement, the rate of preoperational reduction, vulnerability assessment of operation and fixation strength should be considered.

OBJECTIVETo investigate the role of activated hepatocyte growth factor (HGF) in apoptosis of hepatic stellate cells (HSCs) and in modulating the Rho signaling pathway.

METHODSHSCs were divided into the following groups: blank control, consisting of HSCs without treatment; two treatment controls, consisting of HSCs exposed to exogenous HGF at 50 ng/ml and HSCs exposed to exogenous HGF activator (HGFA) at 70 ng/ml; three experimental groups, consisting of HSCs exposed to both exogenous HGF and HGFA, HSCs pre-incubated with the HGF inhibitor c-met at 500 ng/ml for 6 hours and then exposed to exogenous HGF and HGFA, and HSCs pre-incubated with the Rho pathway inhibitor Y-27632 at 10 ng/ml and then exposed to exogenous HGF and HGFA. Activation status of the cultured HSCs was determined by change in expression of alpha-smooth muscle actin (SMA). The optimal intervention concentration of Y-27632 was determined by MTT assay. The apoptotic status of HSCs was determined by flow cytometry. Expression of the HGF-alpha chain was detected by immunofluorescence. The expression of RhoA was evaluated by PCR (for mRNA) and by immunohistochemical staining and Western blot analysis (for protein).

RESULTSExposure to 10 mumol/L Y-27632 led to obvious growth inhibition of HGF + HGFA-induced HSCs, compared with the other concentrations tested (P less than 0.05). HGF + HGFA induced the expression of the HGF-alpha chain in a time-dependent manner (P less than 0.01); however, the increases in expression of HGF-alpha chain induced by HGF alone and HGFA alone were not significantly different from the level in the blank controls (P more than 0.05). Exposure to HGF alone and HGFA alone led to a time-dependent increase in apoptosis (24 h, 48 h, 72 h) but exposure to HGF + HGFA led to the highest levels of apoptosis (P less than 0.05). Exposure to HGF + HGFA led to a time-dependent decrease in RhoA mRNA and protein expression (P less than 0.01).

CONCLUSIONActivation of hepatocyte growth factor promotes apoptosis of hepatic stellate cells by suppressing RhoA expression and down-regulating the Rho signaling pathway.

OBJECTIVETo find out potential molecular targets for gallbladder carcinoma diagnosis and treatment by analyzing and comparing the proteins expressed in human gallbladder carcinoma tissue and benign gallbladder tissue.

METHODSProteomic analysis of 6 human gallbladder carcinoma tissues and 6 benign gallbladder tissues was carried out. Total proteins of the carcinoma tissue and benign gallbladder tissue were separated by two-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed and identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). Immunohistochemistry was used to examine the expression of PEBP1 protein in an independent series of samples.

RESULTSProtein extracts of individual samples in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the gallbladder carcinom tissues. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors while the other eight proteins were underexpressed. The increased level of PEBP1 protein in gallbladder carcinoma was further confirmed by immunohistochemical analysis.

CONCLUSIONSeventeen differentially expressed proteins were successfully characterized by comparative proteomic analysis. Those results may provide scientific foundation for screening the molecular biomarkers which can be used in diagnosis and treatment of gallbladder carcinoma, as well as to improve its prognosis and provide a new clue for carcinogenesis research of gallbladder carcinoma.

OBJECTIVETo confirm whether human MHC class I chain-related A (MICA) induces the amplification of V delta 1 gamma delta tumor-infiltrating lymphocytes (TILs) in vitro and to identify the cytotoxicity of MICA-reactive V delta 1 gamma delta TILs towards epithelial tumor cells.

METHODSMICA protein was prokaryoticly expressed and purified by molecular cloning technology. The purified recombined MICA (rMICA) was used to induce V delta 1 gamma delta T cells from tumor tissues in vitro and the cytotoxicity of these V delta 1 gamma delta TILs were tested by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT).

RESULTSThe rMICA was expressed in prokaryocyte with pET30 as a vector. The immobilized rMICA protein could markedly induce the amplification of V delta 1 gamma delta T cells from tumor tissue in vitro. These V delta 1 gamma delta T cells showed strong cytolytic activities towards tumor cell lines expressing MICA.

CONCLUSIONThe MICA-reactive V delta 1 gamma delta T cell may be a candidate for adoptive cellular therapy of tumors.

OBJECTIVETo explore the potential molecular targets for diagnosis and treatment of gallbladder cancer by analyzing and comparing the proteomes expressed in human gallbladder cancer and benign gallbladder tissues.

METHODSThe proteins expressed were analyzed using two-dimensional gel electrophoresis. The differentially expressed proteins in tumors were also analyzed by mass spectrometry (MS). AnnexinA3 expression was examined by streptavidin peroxidase immunohistochemical technique on paraffin-embedded tissue sections from 50 patients of gallbladder cancer and 38 cases of chronic eholecystitis.

RESULTSProtein extracts of individual sample in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the tissue samples of gallbladder cancer. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors and the other eight proteins were underexpressed. The positive expression rates of annexinA3 in gallbladder cancer was significantly higher than that in chronic cholecystitis, and the difference was statistically significant (74.0% vs 21.1%, P < 0.01). In the gallbladder cancer, no correlation was obtained between annexinA3 and age, gender or histologicl type (P > 0.05), but overexpression of annexinA3 correlated significantly with those cases with a lower histological grading (40.0% vs 82.5%, P < 0.05); lymph node or distant metastasis (40.9% vs 100%, P < 0.05); or a shorter survival time after operation (50.0% vs 93.8%, P < 0.05).

CONCLUSIONSSignificant discrepancies in protein expression exist among gallbladder cancer and benign gallbladder tissues. AnnexinA3 plays an important role in the initiation and progression of human gallbladder cancer.

OBJECTIVE: To establish a simple, sensitive in vitro method to evaluate oxygen/glucose deprivation (OGD)-induced injury of brain hippocampal slices in rats. METHODS: Rat hippocampal slices were incubated in 2% 2, 3, 5-triphenyltetrazolium chloride (TTC) solution after oxygen/glucose deprivation. They were then soaked in a measured volume of ethanol and dimethylsulfoxide (50:50) to extract the TTC formazan Product which was then measured by spectrophotometry. OGD induced LDH release was simultaneously measured. RESULTS: Progressive prolongation of OGD induced hippocampal injury resulted in decreased formazan coloration as determined by spectrophotometry. There was a parallel increase in LDH release, thus a negative correlation in these two products was noted. (r=-0.933,P <0.01). The injury was attenuated in the brain slices pre-treated with nimodipine, dexamethasone, and ketamine, but not ONO-1078. CONCLUSION: Solvent extraction and spectrophotometric quantification of formazan represents an objective measurement of OGD-induced injury of rat hippocampal slices.
