Objective To investigate the mental health and the general well-being among Hangzhou scientific and technical workers,and the mediating effect of coping strategies in perceived level of stress and mental health status.Methods A stratified cluster sampling method were developed among engineering technicians,agrotechnicians,researchers,health works and teaching staff.510 participants were evaluated with perceived stress of different types,Trait Coping Style Questionnaire (TCSQ),General Well-Being Schedule (GWB),and Self-Reporting Questionnaire 20 (SRQ-20).Results There was significant difference among sub-groups with different educational backgrounds,different occupation,and different age group for total scores of perceived stress (F=5.026,5.637,6.421,P＜0.01).Female had significantly higher scores than male on total scores of negative coping factor of TCSQ,total scores SRQ-20 (26.33±6.29,4.36±3.84 vs 24.93±5.68,3.32±3.53) (all P＜0.05).Total scores of negative coping factor of TCSQ,total scores of positive coping factor of TCSQ,and total scores of perceived stress were the significant predictors of both total scores SRQ-20 and total scores of GWB (all P＜0.001).Both total scores of positive coping factor of TCSQ and total scores of negative coping factor of TCSQ mediated the effects of perceived stress on total scores of SRQ-20 (23.87％,29.33％,respectively) and total scores of GWB (24.29％,23.24％,respectively).Conclusion There do exist the mediating effects between coping strategies in perceived stress and mental health status,the improvement of coping modes of scientific and technical workers can be regarded as a useful intervention strategy to improve their mental health status.

Objective:To explore the application value of acoustic radiation force impulse (ARFI) imaging technology in the dif-ferential diagnosis of benign gallbladder wall thickening or gallbladder carcinoma. Methods:Siemens ultrasound ARFI, involving virtu-al touch tissue imaging (VTI) and virtual touch tissue quantification (VTQ), was used to examine the gallbladder wall in 327 cases. To compare transverse shear wave velocity (VTQ) of gallbladder waland VTI image characteristics. Results:Significant differences exist-ed in the gallbladder wall elastic parameters of normal and benign gallbladder wall thickening, as well as thick-walled gallbladder carci-noma. The ROC curve displayed that a velocity of 2.65 m/s can be used to diagnose gallbladder carcinoma, with sensitivity and specific-ity of 94.0%and 93.7%, respectively. Conclusion:The VTQ parameters were significantly different in benign and malignant gallblad-der wall thickening, thereby exhibiting clinical application value.

Objective To build new management model for diabetic foot disease,and to observe the therapeutic effect of diabetic foot ulcers under the new model.Methods 52 patients with newly diagnosed diabetic foot disease were recruited and randomly divided into the experimental group (n=26) and the control group (n=26).While the experimental group adopted the interdisciplinary collaboration model (nurse-doctor jointed diabetes care management model),the control group were treated by the single department pattern.The foot ulcer healing rate,average length of stay (ALOS),fasting plasma glucose (FPG),2 h postprandial blood glucose (2 h PBG),glycosylated hemoglobin (HbA1c),and the patient awareness of the knowledge about diabetes self-management were respectively compared at 3 and 6 months.Results After receiving a multidisciplinary joint diagnosis and treatment,FPG and 2 h PBG of the patients from the experimental group [(6.44±2.93)mmol/L,(8.52± 2.09)mmol/L] were significantly decreased than those of the patients from the control group [(8.17±3.19)mmol/L,(10.77±3.27)mmol/L].HbA1c at 3 and 6 months (7.2％,7.7％) and ulcer recurrence rate (3.8％) after 6 months of patients of the experimental group were significantly reduced than those of the control group(8.9％,9.1％ and 15.4％).When compared with patients of the control group,patients of varying severity in the experimental group showed significantly shortened ulcer healing time and hospital stay.Moreover,patients from the experimental group showed statistically higher knowledge level and self management ability (P＜0.05).Conclusion Through interdisciplinary collaboration,podiatric medical joint management model can significantly improve cure rate,shorten ALOS,improve blood sugar control and patient satisfaction.

Objective To summarize the experience of nursing cooperation in endoscopic sinus surgery for low temperature plasma radiofrequency ablation of skull base tumor, and to explore the safety and feasibility of this technique. Methods A total of 69 patients with skull base tumor were treated with low temperature plasma radio frequency technology to remove skull base tumor. Results Totally 62 cases of skull base tumors completed total resection in low temperature plasma radiofrequency ablation, 7 cases gained subtotal resection. The operation demonstrated superior advantage of less bleeding, short operation time, less postoperative pain and no adverse events. Conclusions The skull base tumor resection for patients with skull base tumors with low-temperature plasma radiofrequency possesses the advantages of short operation time, less bleeding and thermal damage to the surrounding tissues, besides it can reduce the postoperative discomfort, shorten hospitalization time and reduce the occurrence of nursing adverse events.

Objective To investigate the effect of selectiveα1 adrenergic receptor blocking agent in the treatment of bladder neck contracture caused by refractory urinary tract infection in elder.Methods 70 cases of bladder neck contracture were selected and randomly divided into two groups, 35 cases each.Two groups received Ceftriaxone sodium 1 g qd at acute episode,Levofloxacin Hydrochloride 0.5 g tid at non acute phase,control group received the treatment of urethral dilatation, Terazosin hydrochloride 10 mg qd, the experiment group received more with Tamsulosin Hydrochloride Sustained 0.2 mg qd.Two groups were both treated for four weeks.Urinary dynamics index, international prostate symptom score,quality of life score, clinical symptom disappearance time, the number of daily spasm and adverse reactions were compared.Results After treatment, the total effective rate in the experiment group(94.29%) was higher than the control group(65.71%)(P<0.05).Maximum and the average urinary flow rates in two groups increased after treatment(P<0.05), residual urine volume, maximum urethral closure pressure decreased(P<0.05), international prostate symptoms and quality of life score decreased(P<0.05); and compared with the control group, maximum and the average urinary flow rates in the experiment group were higher(P<0.05), residual urine volume, maximum urethral closure pressure were lower(P<0.05), international prostate symptoms and quality of life score were lower(P<0.05), and the average duration of symptoms of bladder neck spasm and the number of daily spasm in the experiment group were significantly shorter than the control group ( P <0.05 ).There was no significant difference in adverse reactions between the two groups. Conclusion Selectiveα1 adrenergic receptor blocking agent in the treatment of bladder neck contracture caused by refractory urinary tract infection in elder was effective, and it can improve the patient's urine flow rate, reduce the residual urine level, increase the quality of life.
