Objective To evaluate long-term follow-up for laparoscopic anterior 180° partial fundoplication for gastroesophageal refulx disease (GERD).Methods A total of 48 patients had undergone a laparoscopic anterior 180° partial fundoplication from July 2004 to October 2007.Patients were followed up at 3 months,12 months,3 years,5 years by using a structured questionnaire via phone or e-mail which evaluated symptoms of reflux,dysphagia,side-effects,and overall satisfaction with the clinical outcome.Results Follow-up data were collected from 43 patients,ranging from 60 to 98 months.Postoperative heartburn significantly improved in 37 patients.Normal belching was preserved in 40 patients,and 38 patients were able to eat normally.Thirty nine (90.7％) patients reported a good or excellent result (minimal or no symptoms) at the late follow-up.Two patients underwent laparoscopic anterior 180° partial fundoplication again due to acid reflux at the 12th and 38th month respectively.Conclusion At minimum 5 years followup,laparoscopic anterior 180° partial fundoplication for GERD is effective and lasting,and most patients are satisfied with the outcome.

Objective To investigate the wake-promoting action of median nerve electrical stimulation(MNES) in coma rats induced by traumatic brain injury(TBI) and its influence on the expression of α1-adrenergic receptor(α1 R) in the prefrontal contex (PFC).Methods Seventy-two healthy Sprague Dawley(SD) rats were randomly divided into the control group,sham-stimulated group(TBI),stimulated group (TBI+ MNES) and antagonist group(TBI+ OX1R antagonist +MNES).The control group had no any treatment.The TBI coma rat models were prepared in the other 3 groups.The sham stimulated group had no treatment.The antagonist group was injected with orexin receptor-l(OX1R) antagonist SB334867 into lateral ventricle,and both the antagonist group and stimulated group received MNES treatment.Then the behavior changes of rats in each group were observed and the α1 R expression level in PFC was detected by using the immunohistochemistry technique.Results Thirteen rats in the stimulated group and 8 rats in the antagonist group revived,while only 4 rats in the TBI group.The α1R levels from low to high were the blank control group,sham-stimulated group,antagonist group and stimulated group,showing the increasing trend,and the difference was statistically significant(P＜0.05).Conclusion MNES can improve the rat consciousness level after TBI coma,and its mechanism may be related with up-regulating the α1 R expression level in PFC area,moreover Orexin-A participates in this regulation process.

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.

Thearticle is aimed to find the correlation between bioactive components of XYE-E and the antidepressant efficacy, by analyzing the immovability time in tail suspension test (TST) and forced swimming test (FST). Using the method of gray relational analysis, correlation analysis and regression analysis, relating the peak area of each common peak of1H-NMR spectra with the immovability time in TST or FST, we found that there were total 14 chemical components identified in the1H-NMR spectrum of XYE-E. Among them, 8 compounds, including saikosaponin a, saikosaponin c, saikosaponin E, saikosaponin F, saikosaponin G, saikosaponin b2, atractylenolide I and atractylenolide II, had significant correlation with antidepressant efficacy.

Objective To investigate the wake-promoting effect of vagus nerve stimulation (VNS) on coma rats after traumatic brain in-jury (TBI), and the related mechanism. Methods A total of 168 healthy Sprague-Dawley rats were randomly divided into blank group, TBI group, antagonist group and VNS group, 42 rats in each group. The latter three groups were established TBI model with impact, and the rats in coma at least 30 minutes were included. VNS group accepted VNS, the antagonist group were injected intralateroventricularly Orexin A receptor 1 (OXR1) antagonist SB334867, and TBI group accepted sham VNS. Their behaviors were observed to determine the level of con-sciousness six, twelve and 24 hours after intervention, while the expression ofγ-aminobutyric acid b1 receptor (GABAb1R) in prefrontal cortex was detected with immunohistochemistry and Western blotting. Results There were 42 rats in the blank group, 11 rats in TBI group, 13 rats in the antagonist group, and 28 rats in VNS group awakened finally. The expression of GABAb1R in prefrontal cortex ranged as TBI group, antagonist group, blank group and VNS group from more to less twelve and 24 hours after intervention under Western blotting (F>60.412, P<0.001), and it ranged as TBI group, antagonist group, VNS group and blank group under immunohistochemistry (H=15.121, P=0.002), with no significant difference among time points (H=3.028, P=0.220). Conclusion VNS can promote waking from coma in rats after TBI, which may relate with the decrease of GABAb1R in prefrontal cortex that induced by Orexin A.

Objective To investigate the drug resistance of side population cells in human gallbladder cancer cell line GBC-SD and explore its mechanism. Methods Drug sensitivity assays of 5chemotherapeutic agents were performed on side population cells (SP) and non-SP cells of GBC-SD.GBC-SD was cultured and then treated with the chemotherapeutic agent gemcitabine. The frequency of SP by FACS was measured. RT-PCR and Western blotting were used to detect the expression of AB-CG2 in both the SP and the corresponding non-SP subsets. Results After 1 d treatment with 4 chemotherapeutic agents (gemcitabine, cisplatin, 5-fluorouracil and mitoxantrone) in IC50 concentration to GBC-SD cell line, the reproductive ability of SP was higher than that of non-SP (P<0.05). However, statistical significance was not achieved when compared with epirubicin (P>0.05). The percentage of SP in GBC-SD treated with chemotherapeutic agent gemcitabine after 3 weeks was sharply elevated by FACS (8.02% ±0.13% vs 0.62% ±0.08%, P<0.05), and the expression of ABCG2mRNA and protein were increased in SP as compared with non-SP. Conclusion SP from human gallbladder cancer cell line GBC-SD, like stem cell, showed a heighten resistance to drugs. Increased expression of ABCG2 was largely responsible for the multi-drug resistance.
