Objective To understand the general self-efficacy level of patients with tuberculosis(TB patients) and its influencing factors, provide evidence for improving the general self-efficacy of TB patients.Methods All TB inpatients in a comprehensive pulmonary hospital were conducted face-to-face survey through a general questionnaire and general self-efficacy scale, self-efficacy level of TB patients and its influencing factors were analyzed.Results Mean scale of general self-efficacy of 402 TB patients was (20.4±4.2), of which only 14 cases(3.5%)showed a high level self-efficacy.163(40.5%), 225(56.0%), and 14(3.5%)patients were with low(10~),medium(20~), and high(30~) self-efficacy scale.The general self-efficacy level of TB patients was influenced by the course of disease(P<0.001), residence(P=0.012), whether or not attended the lecture on tuberculosis education(P=0.034), whether or not conducted physical exercise(P=0.053,stepwise multiple linear regression analysis: P=0.017), working status(P=0.027), No.of hospitalization due to TB(P=0.002), family economic situation(P=0.027), and education level(P=0.020).Conclusion TB patients' self-efficacy level is low, and the general self-efficacy level and its influencing factors should be assessed by health care workers during the follow-up for patients, individualized nursing intervention for improving the TB patients' self-efficacy level should be developed.

Objective To examine the variation of protein expression in nasopharyngeal carcinoma cell lines with different biological characteristics and to identify the radiobiological associated proteins. Methods Biological characteristics of 5-8F and 6-10B were compared by flow cytometry assay after irradia- tion. The total proteins of 5-8F and 6-10B were separated by immobilized pH gradient(IPG) IEF-SDS two- dimensional gel electrophoresis technique. The differentially expressed proteins were cut from the gel and di- gested into peptides for MALDI-TOF MS and the Q-TOF mass spectrometric analysis. Identification of pro- tein was made through searching in protein sequence database. Protein expressions were examined by western blot and immunohistochemistry method. Results Nine most differentially expressed proteins between 5-8F cell and 6-10B cell were identified, p73 and CK19 expression examined by western blot were conformal with that by proteomic method, p73 expression in 5-8F cell was higher than in 6-10B cell. CK19 expression in 6- 10B cell was higher than in 5-8F cell. Conclusion Differentially expression of proteins exist in nasopha- ryngeal carcinoma cell lines with different biological characteristics. These proteins may be associated with cell radiobiological characteristic with the p73 as a potential biomarker.

OBJECTIVETo investigate the feasibility of splenopancreatic-preserving dissection of No.10 and No.11 lymph nodes in radical resection for proximal gastric carcinoma.

METHODSThe data of 62 patients with proximal gastric carcinoma undergoing splenopancreatic-preserving dissection of No.10 and No.11 lymph nodes were analyzed retrospectively.

RESULTSThis splenopancreatic-preserving dissection was effective significantly. The incidences of lymphatic metastasis in No.10 and No.11 were 19.4% and 22.6% respectively, and the incidence of complications was 16.1%, significantly lower than that (40 %) of non-splenopancreatic-preserving dissection.

CONCLUSIONSThe splenopancreatic-preserving dissection of No.10 and No.11 lymph nodes is a safe and feasible method in radical gastrectomy for proximal gastric carcinoma. The surgical procedure is not difficult. With careful operation,the complete clearance of the lymph nodes can be obtained.

Objective To observe the clinical efficacy of modified Huanglian Qingxin Decoction for the treatment of recurrent oral ulcer. Methods Eighty recurrent oral ulcer patients were randomly divided into treatment group and control group by random number table method,40 cases in each group. The treatment group was given oral use of modified Huanglian Qingxin Decoction, and the control group was treated with Zinc Sulfate Tablets and Compound Vitamin B Tablets. Four weeks constituted one course of treatment. The scores of oral symptoms and signs of the two groups were observed before and after treatment,and the short-term effect and long-term effect of the two groups were evaluated after treatment. Results (1)After treatment for 5 days,ulcer area,ulcer pain, congestion area,exudation area,and sleep of the treatment group were much relieved (P < 0.01), and ulcer area,congestion area,and exudation area of the control group were improved (P < 0.05). The treatment group had better effect on improving ulcer area, ulcer pain, congestion area, exudation area, and sleep than the control group (P < 0.01). (2)After treatment for 5 days, the total short-term effective rate of the treatment group was 95.0%,and that of the control group was 72.5%,the difference being significant (P < 0.05).(3) Within one year after the suspension of treatment, total intermission period for ulcer attack in the two groups was prolonged (P < 0.05), and the amount of ulcer foci were much reduced (P < 0.05), the effect of the treatment group being superior to that of the control group(P < 0.05).(4)Within one year after the suspension of treatment,the total long-term effective rate of the treatment group was 70.0%,and that of the control group was 45.0%,the difference being significant (P<0.05). (5)During the treatment,the results of blood and urine routine examination,hepatic and renal function,and electrocardiography showed no abnormal changes. Conclusion Modified Huanglian Qingxin Decoction has better clinical efficacy for the treatment of recurrent oral ulcer than western medicine by relieving clinical symptoms and signs, prolonging the intermission period for ulcer attack, and reducing the total amount of ulcer foci.
