To investigate the antibiotic resistance of bacteria isolated from bile, the bile from the surgical in-patients with bile duct infection from June 1995 to December 1998 was cultured and the distribution and antibiotic resistance of the isolates (not including anaeobes) were analyzed. The results showed that the cultured positive rate in the specimens was 69. 76 % (143/205). Among the isolates, most of them were E. coli and P. aeruginosa (31. 74 % and 18. 56 %, respectively), while Enterobacter, K. pneumonia and Enterococci were also commonly seen. All the isolates were resistant more or less to the commonly used antibiotics.

Traumatic optic nerve injury ( TON) is caused by direct or indirect optic nerve trauma, which is one of a serious complication of craniocerebral trauma. lts prognosis poor and usually bring permanent vision damage. At present, optic nerve injury and regeneration is hot in neurobiology research. To build an ideal experimental animal model is extremely important in research and development in the treatment of optic nerve injury. ln this article, we review the methods of making rat models of traumatic optic neuropathy, clinical similarities, advantages and disadvantages of among these models, to provide reference for more experimental study.

Objective To investigate the expression of microRNA (miRNA)-3620 in the plasma of patients with anti-tuberculosis drug-induced hepatotoxicity (ATDH).Methods A total of 35 patients with ATDH and 35 non-ATDH paired individuals were included in this study.Plasma miRNA-3620 levels were detected using real-time Polymerase chain reaction.Comparison between two groups was done with t test.Receiver operation characteristic (ROC) curve analysis was performed to determine the diagnostic value of miRNA-3620 in ATDH.Results The relative expression of plasma miRNA-3620 of patients with ATDH and non-ATDH were 1.65±1.43 and 0.71±0.45, respectively, with significantly statistical difference (t=3.703, P<0.01).The cut off value of miRNA-3620 expression was 1.15 and the area under ROC curve were 0.71(95% CI: 0.43-1.45).Based on this cutoff value, the sensitivity and specificity of miRNA-3620 in diagnosing ATDH were 60.0% and 82.9%, respectively;the positive predictive value was 77.8% and the negative predictive value was 67.4%.Twenty-one ATDH cases and 29 non-ATDH cases was correctly diagnosed, with the accuracy of 71.4%.Conclusion The expression of miRNA-3620 in plasma is significantly increased in ATDH patients.

Objective To study the efficiency and safety of short-term combination therapy with e-tanercept, methotrexate and eyclophosphamide in the patients with active rheumatoid arthritis. Methods Eighty-four patients with rheumatoid arthritis were included into this study. However, only fifty-six patients were treated with either twice-weekly subcutaneous etanercept, weekly oral MTX and CTX injection every three weeks or twice-weekly subcutaneous etanercept only. The American College of Rheumamatology (ACR) criteria for improvement was used for clinical efficacy assessment and the following laboratory papameters were analyzed:blood routine test, ESR, liver enzymes and renal function parameters, RF and anti-CCP antibody at baseline and the 2,4,8,12,24,36,52 weeks .At the same time ,all the adverse events were monitored throughout the study. Results The improvement of patients who received etanercept shortly, MTX and CTX periodically was as rapid as that of the patients who only received etanercept in ACR20, ACRYO, ESR and CRP (P>0.05). At the end of 36 weeks treatment, the level of anti-CCP antibody in the control group was higher than that of the test group. There was no significant difference between the two groups in adverse events (P<0.05). Conclusion The efficacy and safety of treatment with etanercept, methotrexate and cyclophosphamide in the patients with active rheumatoid arthritis is good.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

OBJECTIVETo study the mechanism of learning and memory dysfuction in the transgenic mouse expressing human tau 40 isoform with P301L mutation (F10).

METHODSThe human tau protein expression and phosphor-tau protein levels were detected with Western blot method. The neurofibrillary tangles were observed with Bielshowsky silver stain. The behavior changes of learning and memory were observed by open field test and passive avoidance test. Acetyleholine level, activities of acetycholinesterase and choline acetyltransferase of whole brain was detected by colorimetry method. The nitric oxide level of whole brain was detected by nitrate enzyme reduction method.

RESULTSExogenous human tau gene was expressed and an elevation of phosphor-tau protein level in 7 and 3-month transgenic mice's hippocampus andcerebrocortex was observed. The neurofibrillary tangles were observed in cerebrocortex of 7-month transgenic mice; the 7-month transgenic mice also presented an evident reduction of learning and memory ability and nitric oxide level of the whole brain, but not changes in acetylcholine level, acetycholinesterase activity, choline acetyltransferase activity and expression in whole brain.

CONCLUSIONTau transgenic mice (F10) can still inherit their parents' biologiccal characters, and develop learning and memory dysfunction awnodh san obvious decrease in nitric oxide level of whole brain in the 7-month old mice, suggesting a decrease of nitric oxide level of whole brain would be involved in the mechanism of learning and memory dysfunction in these transgenic mice.
