Objective To evaluate the efficacy and safety ofbevacizumab combined with FOLFIRI regimen as second-line treatment in advanced colorectal cancer.Methods Sixty-five advanced colorectal cancer patients previously treated with oxaliplatin were divided into test group(33 patients) and control group (32 patients) by random digits table method.The patients in test group received bevacizumab combined with FOLFIRI regimen chemotherapy.The patients in control group received FOLFIRI regimen chemotherapy only.The therapeutic effect was evaluated every 4 cycles.Results In test group,1 patient received complete remission,9 patients had partial remission,the rate of efficacy was 30.3％ (10/33).In control group,non patient had complete remission,3 patients received partial remission,the rate of efficacy was 9.4％ (3/32).The rate of efficacy between two groups had significant difference (x2 =4.45,P =0.035).The median duration of survival was 13.0 months in test group,and 10.3 months in control group(HR =0.58,P=0.038).The median progression-free survival duration was 7.5 months in test group,and 4.4 months in control group (HR =0.45,P =0.003).The median treatment cycle was 12 cycles in test group and 8 cycles in control group.The rate of Ⅲ/Ⅳ grade adverse events in test group was higher than that in control group[72.7％(24/33) vs.46.9％ (15/32)] (P ＜ 0.05).None of these events led to death during the study.Conclusions Bevacizumab combined with FOLFIRI as second-line treatment in advanced colorectal cancer can improve the total remission rate,and prolong the progression-free survival duration and total survival duration with an acceptable adverse reaction.

Objective:To observe the efficacy and safety of docetaxel plus apatinib as a second-line treatment for advanced non-squa-mous non-small cell lung cancer. Methods:From February 2015 to August 2016, 39 eligible patients were randomly assigned to experi-mental arm (19 cases) and control arm (20 cases). Patients in the experimental arm received 60 mg/m2 d1 docetaxel and 500 mg d1-21 apatinib for a 21-day cycle until disease progression or unacceptable toxicity occurred. Patients in the control arm received chemother-apy only. Disease control rate (DCR), incidence of adverse event, and progression-free survival (PFS) were analyzed. Results:The dis-ease control rates (DCR) in the experimental and control arms were 63.2% and 30.0%, respectively, with statistical difference (P=0.039). The experimental arm experienced many grades 3-4 hematologic adverse events with statistical difference (P=0.032). The medi-an PFS values were 5.6 months (95% CI=4.8-6.3) and 3.0 months (95% CI=1.8-4.1) with statistical difference (P=0.04). Conclusion:Docetaxel plus apatinib can be delivered safely with careful monitoring for the treatment of advanced non-squamous non-small cell lung cancer, and this treatment can significantly improve the DCR and PFS.

Objective To explore the impact of nursing intervention on the visual quality of patient after excimer laser refractive correction operation. Methods 400 patients, underwent excimer laser refractive correction operation and regularly followed up more than 6 months, were selected in our hospital from January to December in 2010. The clinical data of 200 patients without nursing intervention were analyzed as control group compared with those of 200 patients receiving nursing intervention as intervention group. Both groups were conducted routine nursing instruction before the operation. The intervention group was given systematic and normative nursing intervention besides routine nursing instructions, including psychological intervention, behavioral intervention, close observation, discovery of adverse reaction in time and giving early disposal. The cooperation reaction of the patients during the operation, and incidence of surgical complications during and post surgery were observed. Results Compared with the control group, the incidence of adverse reactions of visual influence such as incomplete valve during surgery, eccentric cutting after surgery, overcorrection, glare, and refractive regression were significantly lower (P<0.05). Conclusion The implementation of nursing intervention can reduce the adverse reaction of excimer laser refractive correction operation, alleviate the suffering of patients and promote visual quality after surgery.

The objective of the present study was to establish a novel rapid fluorescence focus inhibition test (RFFIT GFP)for the detection of rabies virus antibody, in which a chimeric rabies virus expressing green fluorescent protein (HEP GFP) was used as the basic virus strain in RFFIT GFP assay, and a few serum samples from human, dog and cat were detected by this new method .The optimal serum dilution, virus dosage and infection time were determined in 24 serum samples from human, dog and cat by using RFFIT GFP, RFFIT and ELISA assays. The result showed that these 3 methods gave a good consistency. But RFFIT GFP was found to be more convenient and economic for the detection of rabies virus antibody.

This paper is aimed to report the development of a method for the determination of the binding rate of plasma protein with salvianolic acid B. In vitro, equilibrium dialysis method was used to imitate the binding process between salvianolic acid B and plasma protein, in vivo, ultrafiltration method was used and the binding rate with HPLC was determined. Plasma samples were treated with methanol to precipitate the protein, and the buffer solution was directly determined after filtering. The calibration curve of the buffer solution was linear in the range of 0.5-20 microg mL(-1). The calibration curve of the plasma was linear in the range of 2-200 microg mL(-1). The extract recovery was 68.6%-81.9%. RSDs of intra- and inter-day precisions were all less than 8.5%. The binding rates of plasma protein with salvianolic acid B in vitro was 75.2% and in vivo was 92.1%. This paper shows the high binding power of salvianolic acid B to plasma protein with high sensitivity, good reproduction, simple management and fulfilling the requirement.

Objective To observe the oncololigcal and cosmetic outcomes and complication of breastconserving surgery and radiotherapy for early breast cancer. Methods A total of 78 early breast cancer patients, who were treated in the First People's Hospital of Pingdingshan between January 2001 and September 2008, were identified and followed. Among them, 36 were in stage Ⅰ and 42 in stage Ⅱ. Tangential irradiation was used with a dose of 50 Gy. Tumor bed received a boost dose of 10 Gy electron beam. For axillary lymph node-positive patients, ipsilateral supraclavicular field was hybrid irradiated with 50 Gy X and electron beam.Results The total follow-up ranged from 6 to 98 months. Local recurrence was observed among 4.9% of the patients. The 3-year and 5-year overall survival rate were 96.6% and 92.7% ,respectively. The breast cosmetic satisfaction rate was 94.9%. The main complications reported were acute skin reaction and upper limb edema.Conclusion Breast-conserving surgery and post-operative radiotherapy in early breast cancer patients can lead to satisfactory survival rates and cosmetic effects and hence improved life quality.

This study explored a novel systemic community-based model for detecting and managing people living with HIV/AIDS (PLWHA). Both quantitative and qualitative research methods were used in this study. A quantitative questionnaire investigation was conducted in a sample of 1192 subjects which were randomly selected from two areas with high HIV prevalence, Xiangfan City and Shiyan City of Hubei Province, China. Twenty-two medical and health service staffs were interviewed by semi-structured questionnaire focusing on awareness, status, problems, and suggestions about community-based Voluntary Counseling and Testing and Provider Initiated Testing and Counseling (VCT/PITC). And they were organized to discuss about the aforementioned issues in Xiangfan City and Shiyan City, respectively. Our results showed that the accessibility and availability of the general VCT/PITC were bad. About 28.3% had known and only 4.9% had made use of VCT/PITC. Developing community-based VCT/PITC had some special advantages that can overcome some existing problems to remedy the aforementioned defects. We are led to conclude that, to maximize the availability and uptake rate of the VCT/PITC, we plan to detect PLWHA by developing the community-based VCT/PITC through 4 paths. Then we establish the community HIV health care center constituted of 8 sectors to provide an overall management. Thus, we can effectively detect and manage the PLWHA with a new systemic community-based model.

Objective:To understand the implementation status of case-based payment among healthcare provid-ers and their cognition on the matter. Methods:Semi-structured interview was conducted on 30 purposely selected staff from 9 hospitals in Chengdu. Results:After one-year implementation of case-based payment, hospitals at different level carried out the policy vigorously:executed corresponding expense control measures and management. Neverthe-less, the proportion of cases that were paid with case-based payment was low, moreover the inclusion criteria for case was of disunity and the formulation of the expense standard was ambiguous to some extent. Conclusion:Certain achievements were accompanied with problems, so it is essential to refine reimbursement standards, improve case-based payment, make clear the inclusion criteria for case and extend the covering range of case-based payment in Chengdu. In addition, the medical insurance agency should strengthen the supervision of healthcare providers,and guide them to set up effective incentive mechanism.
