Objective To describe the status of the self-efficacy and coping styles of tuberculosis patients,analysis the relationship between self-efficacy and coping styles. Methods With the method of convenient sampling, used the general information questionnaire self-designed, General Self-Efficacy Scale (GSES) and Medical Coping Modes Questionnaire (MCMQ) to take questionnaire survey on 132 patients with pulmonary tuberculosis.Applicated SPSS19.0 software for the statistics, and analyzed the relationship between self-efficacy and coping styles on patients with pulmonary tuberculosis. Results The mean score of self-efficacy in 132 pulmonary tuberculosis patients was 24.90 ± 7.04,which was in the medium to low level. The proportion of mediun,lower,higher level of self-efficacy was 44.70% (59/132), 39.40%(52/132),15.90%(21/132).Scores of the coping styles on face,avoid, yield were 21.16±9.23,16.55± 2.83,9.68 ± 4.12.Patients self-efficacy level was positively correlated with face coping style (r=0.242, P<0.05), avoid coping style (r=0.150, P<0.05),and negatively correlated with the yield response (r=-0.008, P<0.05). Conclusions The general self-efficacy level of tuberculosis patients is at a lower level. Tuberculosis patients should have more choice to handle it.

Objective To investigate effect of carnosine on oxygen glucose deprivation/reperfusion ( OGD/RP) induced injury in rat brain slices. Methods Injury of brain slices was determined by TTC methods.The contents of ATP, ADP and AMP were determined by high performance liquid chromatography.Reactive Oxygen species ( ROS) were determined by fluorescence methods.Results Compared with control group, rat hippocampal slices were significantly damaged by OGD/RP, indicated by light color and decreased A490 nm value of TTC staining.Meanwhile the contents of ATP and ADP were significantly decreased, and the content of AMP and ROS were significantly increased, the difference between two group was significant ( P<0.01).Pre-incubation with Carnosine (1000, 200, 40 μg/mL) significantly inhibited the light color and decreased A490 nm value of TTC staining, increased the contents of ATP, ADP and AMP, and decreased the content of ROS, the difference between two group was significant ( P <0.01 ) . Conclusion Carnosine can protect rat hippocampal slices against injury induced by OGD/RP, which may relate to improve the energy metabolism and strengthen the ability of anti-oxidative stress.

Objective To compare the safety and effectiveness of duodenum-preserving pancreatic head resection (DPPHR) with pylorus-preserving pancreaticoduodenectomy (PPPD) in the treatment of chronic pancreatitis with a pancreatic head mass.Methods Medline,Biosis,Cochrane Library,Science Citation Index Database,CBM Database,Wan Fang and CNKI were searched systematically.The bias risk of the included trials was assessed according to the assessing tools as suggested by the Cochrane Handbook.Review Manage 5.2 was used to perform the statistical analysis.Results 7 RCTs with 226 patients were included in the meta-analysis which showed that there were no significant differences between PPPD and DPPHR in overall postoperative morbidity,postoperative hospital stay,complete pain relief,pancreatic fistula,exocrine insufficiency,symptom score at 5 to 7-year follow-up,and quality of life score at 14 to 15-year follow-up (P ＞ 0.05).While DPPHR had significant superiorities in operation time,blood replacement,delayed gastric emptying,occupational rehabilitation after the operations,weight gain,quality of life score at 1 to 2-year follow-up,symptom score at 5 to 7-year follow-up,and physical functioning score at 14 to 15-year follow-up.Conclusions DPPHR is more favourable than PPPD in reducing the use of blood replacement,shortening operation time,delayed gastric emptying,occupational rehabilitation after the operations,weight gain,physical functioning,and in improving quality of life of patients.

Objective To explore the value of 64-row helical CT multi-phase enhancement scan combined with angiography (CTA)in the diagnosis of pulmonary mass.Methods Two hundred and sixty-five patients with pulmonary mass confirmed by pa-thology were checked,analyzed the CT sign of multi-phase enhancement scan and the blood supply of pulmonary mass displayed by CTA.Results Lung cancer was mainly supplied by bronchial arteries,some by body arteries,the feeding arteries display rate of lung cancer group was significantly higher than that of benign disease group(P <0.05).CT enhancement peak value of lung cancer group was significantly higher than that of tuberculoma group,inflammatory pseudotumor group and hamartoma group(P <0.05), but no significant difference between hemanginoma group(P >0.05).Enhancement dynamic curves of lung cancer group was differ-ent from benign lesion groups:Lung cancer without obvious enhancement in pulmonary artery phase,CT value increased rapidly in aorta phase,120 s reached peak,and declined slowly in delay phase;CT value of tuberculoma was increased slowly without obvious peak;CT value of inflammatory increased gradually in pulmonary artery phase,90 s reached the peak;hamartoma was no obvious enhancement;Hemangioma enhanced rapidly after strengthening in the pulmonary artery phase,reached the peak at about 15 s,and then decreased slowly.Conclusion 64-row helical CT multi-phase enhancement scan combined with angiography have important clinical value,which can differentiate malignant mass from benign ones.

Objective To analyze the clinical features of patients with traumatic brain injury in the Ya' an earthquake and discuss the treatment experiences.Methods Medical records of 69 patients admitted from April 2013 to May 2013 because of traumatic brain injury in the Ya' an earthquake were collected.Retrospective review was performed for age,gender,causes of injury,time from injury to hospitalization,types of injury,associated injury,treatment methods and outcomes.Results There were 47 males and 22 females.Forty-two patients (61％) were injured from falling objects.Fifty-eight patients (84％) were sent to the West China Hospital within 72 hours postinjury.Twenty-two cases (32％) sustained associated injuries.Twenty-nine patients (42％) were critically injured.Twenty-four patients underwent operation at the local hospital and twelve patients had operation at our hospital.Outcome measure using GOS one month after treatment showed 55 favorable recovery,5 moderate disability,4 severe disability,and 5 coma.Conclusions Main cause of injury is hit by falling objects during the Ya' an earthquake.Majority of the patients obtained effective treatment in the time window.GCS in combination with patients' general condition used in casualty triage and critical patients charged by neurosurgeons and treated with the cooperation of multiple disciplinary teams are helpful to successful treatment.

Objective To explore the impact of different hemoglobin on postoperative cognitive functions in female patients underwent laparoscopic surgery. Methods 215 female patients who were underwent laparoscopic total hysterectomy or laparoscopic myomectomy from January 2016 to December 2016 in our hospital were selected. The patients were divided into 3 groups according to their hemoglobin:Group N with normal hemoglobin ,Group A with hemoglobin concentration of 9 ~ 11 g/L ,and Group B with hemoglobin concentration of 6 ~ 9 g/L. Same anesthesia and recovery plan were performed in all patients. Basic and operative information were recorded. The score of MoCA on the day before surgry ,the day after surgry ,3 days after surgry and 30 days after surgry were recorded. Blood samples were collected on the day before surgry and the day after surgry for the determina-tion of serum S-100β protein and IL-6 concentrations. Results No significant difference was found in basic and operative information among three groups. The recovery time was much longer in Group B than that in Group N. No difference were found among three group in the score of MoCA on the day before surgry and 30 days after surgry ,while the score in the day after surgry and 3 days after surgry were lower in Group B com-pared with Group N. The incidence of POCD were higher in Group B compared with Group N. Compared with the day before surgry ,the concentration of serum S-100β protein and IL-6 were much higher. And compared with Group N ,the concentration of serum S-100β protein was higher in Group A and B in the day after surgry , while IL-6 was higher in Group B. The concentration of serum S-100βprotein and IL-6 were much higher in Group B compared with Group A in the day after surgry. Conclusion Female patients with hemoglobin concen-tration of 6 ~ 9 g/L are susceptible to POCD ,which might be contributed by operative central nerve system damage induced by excessive inflammation.

Objective To investigate Helicobacter pylori combined with N-methyl-N-nitrosourea (MNU) gavage for preparing balb/c mouse gastric cancer model.Methods Eighty balb/c mice were randomly divided into four groups after 1-week adaptive feed,normal group,model group Ⅰ,Ⅱ and Ⅲ,20 cases in each group.The model group Ⅰ,Ⅱ and Ⅲ were given Helicobacter pylori bacteria liquid (CFU=109/mL) gavage,once every other day for 5 times;then,the freshly configured MNU solution 0.15,0.3,0.6 mL gavages were in turn given,MNU and pure water allocation ratio was 5mg:3mL.Once gavage per week for continuous 10 weeks.Results The model group II had 66.67% adenocarcinoma,the model group I were gastritis with mild atypical hyperplasia,and all mice in the model group III died.Conclusion This method can prepare the gastric cancer model.

OBJECTIVE To investigate the uses of antibacterials,the characteristics of bacterial distribution and the drug resistance and provide a foundation for reasonable application of antibacterials.METHODS Germs isolation and cultivation were carried out according to National Clinical Testing Operation Procedures(2nd edition).Germs definition and resistance test were carried out by using VITEK 2 Compact microbiological assay system.Statistical analysis was processed by using WHONET 5.4.RESULTS Totally 7815 strains of bacteria were isolated from clinical samples,most of which were Gram-negatives(G-)(58.0%,56.3% and 59.5%,respectively in the 3 years).The tendency of Gram-positives(G+) didnot charee obviously(about 20%).Theresistance were increasing.The resistance rate of Staphylococcus aureus was more than 70.0 % to the most antibacterials.Up to now,there was no vancomycin-resistant isolate.CONCLUSIONS We should use antibacterials reasonably and efficiently to delay and control drug resistance,according to the susceptibility test.
