Objective? To explore the establishment and effects of preventive nursing sensitivity indicators for venous thromboembolism (VTE) in orthopedic patients. Methods? Preventive nursing sensitivity indicators for VTE in orthopedic patients were established using Delphi expert consultation method. Totally 160 patients before the preventive nursing sensitivity indicators for VTE were carried out (May 2017) were selected as the control group, while another 201 patients after the indicators were carried out (November 2017) were selected as the study group. Patients in the control group received conventional preventive nursing care for VTE, whereas patients in the study group received monitoring and management using the self-developed preventive nursing sensitivity indicators for VTE. Patients' incidence rate of VTE, satisfaction with VTE prevention, accuracy of VTE risk assessment, awareness rate of health education knowledge, implementation rate of physical prevention measures, achievement rate of nurses' VTE-associated knowledge and skills before and after the indicators were carried out. Results? Patients' incidence rate of VTE was 25‰ before the indicators were carried out, while that after the indicators were carried out was 5‰ (P=0.175); patients' satisfaction before the indicators were carried out was 78.12%, while that after the indicators were carried out was 93.53% (χ2=18.344, P＜0.001); and there were statistically significant differences in accuracy of VTE risk assessment, awareness rate of health education knowledge, implementation rate of physical prevention measures and achievement rate of nurses' VTE-associated knowledge and skills before and after the indicators were carried out (P＜ 0.01). Conclusions? The establishment and application of preventive nursing sensitivity indicators for VTE can effectively improve the nursing quality of VTE prevention as well as patient's satisfaction.

Objective To investigate the microbiological trends and antibiotic susceptibility of peritoneal dialysis(PD)-related peritonitis (PDAP).Methods All patients who developed PDAP between 2004 and 2015 in Renji Hospital,Shanghai Jiao Tong University School of Medicine were enrolled.Demographic data,results of dialysate pathogen culture and drug susceptibility test were recorded.The trend of peritonitis incidence was measured by Poisson regression and the chi-square test or Fisher exact test method was used to compare the composition of causative organisms and their antimicrobial susceptibilities over time.Results During the study period,a total of 711 episodes of PDAP were occurred in 386 patients.The culture positive rate of pathogens rose from 52.0％ in 2004 to 77.0％ in 2015 (P ＜ 0.001).The distribution of causative organisms of the culture positive peritonitis was gram-positive bacteria (270,59.5％),followed by gram-negative bacteria (129,28.4％),polymicrobial(39,8.6％),fungi (15,3.3％) and mycobacteria (1,0.2％).From 2004 to 2015,the incidence of peritonitis decreased from 0.214 to 0.160 episodes/patient·year (P=0.034).The incidence of coagulase-negative staphylococcus peritonitis decreased from 0.049 to 0.027 episodes/patient · year (P=0.025),while others had no significant change;A significant decline was observed in the sensitivity of Gram-positive strains to the first generation cephalosporin and ampicillin/sulbactam in 2010-2015 group compared with those in 2001-2009 group (61.3％ vs 88.2％,P ＜ 0.001;61.7％ vs 85.5％,P=0,001),whereas the sensitivity to vancomycin remained the same.The sensitivity of Gram-negative strains to ceftazidime and amikacin showed no significant change.As for the gram-positive peritonitis treated with cefradine as empirical treatment,compared with those in 2004-2009 group,in 2010-2015group the proportion of patients requiring to change their treatment regime was significantly higher,and the treatment course was longer.Conclusions A gradual decline is observed in the incidence of PDAP and the culture positive rate of pathogens improves.Peritonitis caused by coagulase-negative staphylococcus decreases overtime.The present empirical treatment protocols may need re-evaluation considering the decreased rate of the first generation cephalosporin sensitivity in recent years.

Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

OBJECTIVE: To analyze the clinical significance of ocular vestibular evoked myogenic potentials (oVEMP) and cervical vestibular evoked myogenic potentials (cVEMP) in primary unilateral benign paroxysmal positional vertigo (BPPV). METHOD: Fifty-two patients with unilateral primary BPPV (BPPV group) and 38 normal subjects (control group) received ocular vestibular evoked myogenic potential (oVEMP) and cervical vestibular evoked myogenic potential (cVEMP) test using tone burst stimuli. The response rate, latency and amplitude were analyzed. RESULT: In BPPV group, the response rate of oVEMP was 46.15% in lesioned side and 48.08% in healthy side, respectively. The response rate of cVEMP was 67.31% in lesioned side and 65.38% in healthy side, respectively. In control group, the response rate on the left ear was 84.21% for oVEMP and 92.11% for cVEMP. On the right ear, was 81.58% for oVEMP and 94.74% for cVEMP in control group, there was no significant difference in cVEMP and oVEMP P1, N1 N1-P1 latency and amplitude between left and right ear. The interaural amplitude ratio and asymmetry of cVEMP and oVEMP was significantly different between BPPV group and control group (P<0.05). CONCLUSION Unilateral primary BPPV with bilateral impaired vestibular otolith pathways function can be objectively evaluated by oVEMP and cVEMP detection. Abnormal oVEMP responses were more frequently detected than cVEMP.

Objective To investigate the roles of a variety of cytokines including transforming growth factor beta (TGF-β),interleukin-6 (IL-6) and interleukin-2 (IL-2) in the differentiation of CD+4 Tlymphocyte cells.Methods T lymphocyte cells either in human peripheral blood or routine spleen were cultured in vitro under different stimulation conditions.Flow cytometry was used to analyze the percentages of CD+4IL-17+ T-helper 17(Th17) cells,CD+8 IL-17+ T cells,CD+4 CD+25 FOXP+3 T regulatory (Treg) cells among activated T cells.Results Differentiation of Treg cells,Th17 cells and CD+8 IL-17+ T lymphocyte cells was enhanced when murine splenic T cells were cultured with TGF-β.The levels of expression were (7.8±2.2)%,(12.6±3.1)%,(10.1±2.6)% ,respectively.Experimental control group was severally same type of T cells without cytokine treatment.The levels of expression were (4.8±0.6) %,(1.7±0.5) %,(1.0±0.4) %,respectively.There were statistically significant differences among them (q=4.09,8.80,9.61.P<0.05 or P<0.01).Under combination treatment with IL-6 and TGF-β,(17.8±5.3) % Th17 cells and (15.0±4.2)% CDCD+8 IL-17CD+ T cells were induced,whereas the levels of Treg cells whose differentiation were restrained were (4.1±1.2) %.The differences were statistically significant compared with the level of same type of T cells in TGF-β group (q=5.03,5.17,5.04,P<0.01).Moreover,combination treatment with IL-2 and TGF-β decreased percentages of Th17 and CDCD+8 IL-17CD+ T cells and increased percentages of Treg cells in T cell population.There was an opposite effect when anti-IL-2 was apphed.The percentages of Th17 and CD+8 IL-17+ T cells were increased and the percentages of Treg cells were reduced The regulation trend of T lymphocyte cells in human peripheral blood was similar with those in routine spleen.Conclusion Various cytokines are of great importance in the regulation of the balance between Th17 and Treg cell.

Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.

Objectives To investigate the practical application of modified peritoneal equilibration test (modified PET) employing 4.25% glucose exchange in peritoneal dialysis patients and to assess the reference values and clinical significance of the test. Methods Modified PETs were performed in 97 patients without peritonitis for at least 4 weeks. Mass transfer area coefficient (MTAC) was calculated according to the Garred model. Creatinine D/P concentration ratio at 4 hr (4 h D/Pcr), sodium D/P concentration ratio at 1 hr (1 h D/PNa+) and net ultrafiltration (nUF) were also assessed. Ultrafiltration 0.05). 4 h D/Pcr and MTACcr of modified PET were significantly correlated with 4h D/Pcr of standard PET (P
