Objective:To explore the mediating effect of professional self-efficacy between professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.Methods:A total of 391 nursing students from Chengdu area full-time university were investigated by general information questionnaire, gerontological nursing career motivation questionnaire, professional values scale, and professional self-efficacy scale. Pearson correlation analysis and descriptive statistical analysis were performed by SPSS 21.0. Amos 26.0 was used to establish mediating effect model and verify the mediating effect.Results:The total score of 391 nursing students' willingness to work on gerontological care was (47.05±6.93), the willingness to work on gerontological care was positively correlated with professional self-efficacy and professional values ( r = 0.826, 0.775, respectively, all P<0.01), and professional self-efficacy played a partial mediating role between professional values and willingness to work on gerontological care, accounting for 64.82% of the total effect. Conclusions:The willingness to work on gerontological care of nursing students in higher vocational colleges is at a middle level. Professional values not only directly affect the willingness to work on gerontological care, but also indirectly take function through the professional self-efficacy. Professional self-efficacy plays a mediating role in professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective: To explore HIV-1 drug resistance and influencing factors among people living with HIV/AIDS before antiretroviral therapy in Liangshan Yi Autonomous Prefecture (Liangshan). Methods: Between January 1 and June 30, in both 2017 and 2018, a cross-sectional survey was conducted in Liangshan HIV-1 pol sequences were gathered and analyzed according to WHO Guidelines on HIV drug resistance surveillance of 2014. Both HyPhy 2.2.4 and Cytoscape 3.6.1 software were used to analyze the drug resistant strains of HIV-1 transmission network. Results: A total of 464 people living with HIV/AIDS was recruited. The proportion of HIV-1 CRF07_BC subtype was 88.6% (411/464), with HIV-1 drug resistance rate was 9.9% (46/464). The HIV-1 drug resistance rates of non-nucleoside reverse transcriptase inhibitors (NNRTI), nucleoside reverse transcriptase inhibitors(NRTI) and protease inhibitors (PI) were 6.7% (31/464), 1.9% (9/464) and 0.4% (2/464) respectively. New recombinant strains of HIV-1 URF_01BC subtype was independently clustered according to the drug resistant mutation sites. Results from the multivariate logistic analysis showed that injected drug users group had higher risk on HIV-1 drug resistance (aOR=3.03, 95%CI:1.40-6.54) than heterosexual group among people living with HIV/AIDS. Conclusions HIV-1 drug resistance rate had already been in a high level before antiretroviral therapy was in place. The newly identified recombinant strains of HIV-1 URF_01BC subtype were independently clustered according to the drug resistant mutation sites. It was necessary to strengthen the prevention of the HIV-1 drug resistant strains transmission.

Objective To evaluate the effect of modified bowel preparation-Polyethylene Glycol Electrolytes Powder (SF-PEG, Shu Taiqing) in combination with magnesium sulfate in patients with constipation undergoing colonoscopy. Methods Sixty cases from mild to moderate constipation were randomly divided into two groups:Group A: SF-PEG (438.4 g, 4 L), 30 cases; Group B: received low-dose SF-PEG (219.2 g, 2 L) and 50.00%magnesium sulfate 50 ml, and then 250 ml water, 30 cases. Boston Bowel Preparation Scale scores (BBPS) and bubbles in bowel lumen score were assessed by the same endoscopist blindly to the preparation regimen, and the time of colonoscopy and the tolerability was recorded. Results All patients underwent completely the bowel preparation and colonoscopy. The time of colonoscopy of group B was shorter than that of group A (P < 0.05). The BBPS score of group B was higher than that of group A (P < 0.05). The bubbles in bowel lumen were less in Group B than in Group A (P < 0.05). The willingness to retake in Group B were superior to those in Group A (P < 0.05). No significant difference was found in score of total adverse effects and taste score between the two groups (P > 0.05). Conclusion SF-PEG in combination with magnesium sulfate in patients with constipation for colonoscopy can improve tolerance to bowel preparation, cleanliness and effects of examination. It's safe to be recommended in clinical practice.

Objective To compare the vascularization of collagen scaffolds with or without growth factors and their efficacy on cardiac function in postinfarcted rats underwent surgical ventricular restoration.Methods Collagen scaffolds were activated with 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride chemistry (EDC) as control or continually covalently immobilized with vascular endothelial growth factor (VEGF) and VEGF + basic fibrohlast growth factor (bFGF) as experimental groups.Adult SD male rats underwent left anterior descending artery (LAD) ligation to generate transmural myocardial infarction(MI).Four weeks later,by echocardiography,rats with moderate scar size(25％-35％ akinetic area of freedom wall of left ventricle) were screened out,assigned into 3 groups randomly and received the surgical ventricular restocation (SVR).Then,cardiac function was measured by echocardiography at 1w,2w and 4w after patch implantation.At endpoint of study (4w after patch implantation),the rats were sacrificed and the hearts were harvested.Vascularization of patch were determined by capillary density (evidenced by vWFⅧ staining) or mature vessel density (evidenced by SMA staining) respectively.Results The general mortality of the animal model is 15％ (6/40).A significant improvement of cardiac function was observed in all animals at 1 w after patch implantation but that was better preserved in both cytokine-conjugated groups 4w later (control group vs.VEGF group,P ＜ 0.05,control group vs.VEGF + bFGF group,P ＜ 0.01).More capillaries were present in patch with growth factors (P ＜0.05),while significant functional vessel formation was observed only in VEGF + bFGF group (P ＜0.01 vs.control or VEGF group).Additionally,we identified a positive correlation between heart function and mature vessel density (P =0.0297,r2 =0.998).Conclusion The mechanical property of collagen scaffold can be effectively improved by EDC,the growth factors immobilized in scaffold were in favor of vascularization of patch,which may facilitate the preservation of cardiac function posterior to SVR.

Objective To determine the influence of serum complement and IgG on rituximabdependent NK cell-mediated cytotoxicity to Raji cells in vitro.Methods FcγR Ⅲ a (CD16a) polymorphism of NK cells were detected by nest-PCR. Effects of serum IgG on FcγRⅢ a expression of NK cells in vitro were analyzed by flow cytometry.The target cells(Raji cells) were stained with DIO,cultured with effector cells(NK cells) and rituximab with or without serum IgG/complement,and finally stained with propidium iodide (PI),then these cells were tested by flow cytometry and the cytotoxic index was calculated as well. Results The cytotoxic indexes of the ADCC +CDC groups were higher than those of ADCC groups, but the serum IgG groups were lower than the ADCC groups. In FcγRⅢa-158Ⅴ/Ⅴ groups, the cytotoxic indexs of the ADCC+ CDC groups,the serum IgG groups and the ADCC groups were (94.25±1.79) ％,(59.79±0.66) ％ and(69.05± 2.38) ％,respectively,and the differences among the groups were statistically significant (P＜ 0.05).In FcγRⅢ a-158Ⅴ/F groups,the cytotoxic indexs of these three groups were (66.71±5.57) ％,(18.13±2.99) ％ and (39.63±3.86) ％, respectively, and the differences among the groups were also statistically significant (P＜ 0.05).Conclusions Complement may enhance the rituximab-mediated NK cell cytotoxicity to Raji cells, whereas,serum IgG may weaken the cytotoxicity against Raji cells. It is clued up that for patients treated by tumorspecific monolonal antibody (MAb), combined infusion of fresh frozen plasma could promote its anti-tumor effect,however,MAb combined with IVIG may impair its anti-tumor effect.

Positive linear correlation was found between TSH level and detection rate of congenital hypothyroidism (CH). When measured with a cut-off point at 9, 10, 15 and 20 mU/L of TSH, the sensitivity of positive detection rate for CH was 99.77%, 96.80%, 81.25% and 71.88%, respectively. TSH > 9 mU/L seems to be a reasonable cut-off value.

BACKGROUND: Independent urination and defection functions do not exist in patients with paraplegia above T12 because the injury disrupts the connection to the brain.OBJECTIVE: To reconstruct urination and defecation functions in patients with paraplegia with vascularized intercostal nerve transfer to sacral nerve roots with selected interfascicular anastomosis.DESIGN: Self-control observation.SETFING: Department of Orthopedics, Changhai Hospital of the Second Military Medical University of Chinese PLA.PARTICIPANTS: We recruited 30 patients with traumatic paraplegia at T9-L2 who received treatment in the Department of Orthopedics,Changhai Hospital of the Second Military Medical University of Chinese PLA, from January 1990 to December 2000. Paraplegia plane at T9-T11was found in 17 cases and paraplegia plane at T12-L2 in 13 cases. All the cases had undergone vertebral lamina decompression and internal fixation, 24 of whom had an additional operation to remove the internal fixation.METHODS: Two normal vascularized intercoastal nerves and artery and vein (intercostals nerves were generally at ribs 7 and 8 or 9 and10)above the spinal cord injury site were harvested by cutting in at their distal ends at the midclavicular line and separating the proximal ends from the levatores costarum. The nerves were then transferred to the vertebral canal through a submuscular tunnel. A sural nerve segment that had been harvested and sheared into two segments was sutured to the intercostal nerves by epiperineurial neurorrhaphy and then to the S2-4nerve roots by interfascicular neurorrhaphy. For patients with spinal injury plane below T11, intercostal nerve or subcostal nerve among the 10th and 11th ribs were harvested from the incision of abnormal wall. The nerves were transferred to the lumbar part through the channel of lateral abdominal wall. The transplanted sural nerve was conrected to S2-4 nerve root of partial nerve tract cut alternatively and exposed from S1,2 plane posterior. Defecation function of the patients was evaluated at postoperative 1, 3, 6, 12 and 24 months and follow-up; urodynamic examination was performed before and after operation.patients.RESULTS: A total of 30 patients were followed up for 5 years on average,tion and defecation functions of the patients: 26 (86.6%) had recovered defecation and urination sensation, 23 (76.7%)regained the micturition reflex and uriesthesis; 19 (63%) had recovered function of the detrusor The postoperative maximum urine flow ratio, surplus urine volume, and the maximum systolic pressure of detrusor muscle were obviously improved as compared with those before operation [(12.0±3.0) vs (2.0±0.3) mL/s,(80±12) vs (150±30) mL, (11.76±3.43) vs (5.88±1.47) kPa, P ＜ 0.05]. Postoperative low compliance was found in 9 cases, and detrusor areflexia in 7cases. The number was both significantly decreased as compared with that of preoperative cases (26 and 27 respectively).CONCLUSION: Transfer of vascularized intercostal nerve to S2-4 nerve roots with selected interfascicular anastomosis can reconstruct partial urination and defecation functions, and sensation in buttock, perineal region and cunnus region in paraplegia.
