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.

Plasma viral RNA load is widely accepted as the most relevant parameter to assess the status and progression of Simian immunodeficiency virus (SIV) infections. To accurately measure RNA levels of the virus, a one-step fluorescent quantitative assay was established based on the SYBR green Real-time reverse transcription-polymerase chain reaction (RT-PCR). The lower detection limit of the assay was 10 copies per reaction for the virus. This method was successfully applied to quantify SIVmac251 and SIVmac239 viruses produced in CEM×174 cells. Additionally, the performance of the SYBR green RT-PCR was assessed in a SIVmac251 infected rhesus macaque. The result demonstrated that the method could detect as little as 215 copies per milliliter of plasma and the dynamic pattern of viral load was highly consistent with previous results. With regard to convenience, sensitivity and accuracy our assay represents a realistic alternative to both branched-chain DNA (b-DNA) assays or real-time PCR assays based on TaqMan probes.

ObjectiveTo investigate the effect of neoadjuvant chemotherapy in locally advanced cervical cancer on cell cycle,proliferation,and evaluate the feasibility of proportion of cell in different phase and proliferating cell nuclear antigen(PCNA) as sensitive indices to assess chemotherapeutical sensitivity and therapeutical effect.MethodsForty-nine cases of locally advanced cervical cancer were divided into response group and no-response group according to the clinical efficacy of neoadjuvant chemotherapy.Compared the proportion of cell in different phase and proliferation index of PCNA between two groups.The clinical therapeutic effect was evaluated after 4 weeks in the second neoadjuvant chemotherapy regimen.Results In 49 patients with locally advanced cervical cancer,clinical effective of 39 cases (response group),no effective of 10 cases(no-response group).The S-phase proportion of cell in the pre-neoadjuvant chemotherapy and post-neoadjuvant chemotherapy of response group[ (21.47 ± 5.21 )% and(18.32 ±5.07)%] were higher than those of no-response group [ (9.63 ± 2.58)% and ( 10.14 ± 2.32)% ] (P < 0.05 ).The proliferation index of PCNA of cervical cancer in the pre-neoadjuvant chemotherapy of response group [ ( 81.67 ± 7.14)% ] was higher than that of no-response group [ (66.99 ± 2.29 )% ] (P < 0.05 ).Conclusion The S-phase proportion of cell and proliferation index of PCNA in the pre-neoadjuvant chemotherapy are important indexes to assess chemotherapeutical sensitivity and therapeutical effect.

Background and purpose: Magnetic resonance spectroscopy is currently the only non-invasive magnetic resonance imaging technique which can detect metabolite composition of live organ and tissue and also conduct semi-quantitative or quantitative analysis. We analyzed the characteristics of metabolic changes among normal liver, cirrhosis regenerative nodule and liver cancer on the background of cirrhosis by voxel proton MR spectroscopy at 1.5 Tesla. Methods: 20 healthy volunteers (control group), 25 cirrhosis (cirrhosis group) and 23 hepatocellular carcinoma after cirrhosis (HCC group) patients were our candidates. The characteristics of spectra of ~1H-MRS were observed. The height and ratio of choline complex (Cbo) and lipid methylene (Lip2) were recorded and the results were compared among the groups. Results: The success rate of ~1H-MRS was about 88.2% (60/68). There were statistically significant differences among the heights of Lip2 peak of the three groups, and also between that of the control group and the group of liver cancer. But there were no significant differences between that of control group and cirrhosis group, cirrhosis group and liver cancer group. The comparison of the height of Cho peak and the ratio of Cho/Lip2 showed statistically significances both among the three groups and between each other. Conclusion: The metabolic changes of the liver could be shown non-invasively by ~1H-MRS, which could be useful for differential diagnosis or diagnosis of cirrhosis regenerative nodule and HCC.
