Objective To study the effect of psychological nursing on heart rate variability (HRV)in patients with acute myocardium infarction. Methods 80 patients with AMI were randomly divided into group A(routine nursing group)and group B (psychological nursing group) with 40 patients in each group,HRV was evaluated in both groups.The time domain and frequency domain of HRV of 24 h sinus rhythm in two groups of patients were analyzed. Results In group B,24 h average standard deviation of RR interval (SDNN),5 min segments of continuous average standard deviation of RR intervals (SDANN),the difference between adjacent cardiac RR interval of the root mean square (rMSSD),the percentage of adjacent canrdiac RR interval greater than 50 ms (PNN50),low frequency (LF),high frequency (HF) and other HRV parameters were significantly higher than group A. Conclusions Psychological nursing can significantly increase HRV and improve the electric stability of the ischemic myocardium.Psychological nursing can stabilize emotion of patients,decrease sympathetic tone,and may have a role in the prevention of sudden death.

Objective To evaluate the clinical value of CT scanning in preoperative location diagnosis of cryptorchidism.Methods 21 patients with eryprorchidism aged frorri 1 to 50 had neither signs nor ultrasonic indication and got CT scanning before operation,all of them were confirmed by operation.Results 2 of 21 were bilateral and 19 were unilateral after operation.CT scanning indicated all of them correctly.Conclusion CT scanning has fast speed,higher resolution and less subjective than ultrasonogmphy.CT scanning can show structure of testis and peripheral tissue better especially with contrast agent.CT scanning in preoperative location diagnosis of cryptorchidism has high accuracy.

Objective To study the CT symptom and diagnosis value of pancreatic trauma. Methods Retro-spectively analyzed the CT and clinical data of 11 pancreatic trauma. Results Bleeding,edema in pancreas parenehy-ma, uprightness low density lines appear along long axis of pancreas when enhancement were performed ,which werethe direct symptom of pancreatic trauma and rupture; hematoeele, hydrops around pancreas, front fascia of left kidney broaden, pancreatic pseudoeyst pneumatosis in bile duet, which were the indirect symptom of pancreatic trauma. Con-clusion CT is the first choice in the diagnosis of pancreatic trauma. Master the CT symptom and make right diag-nosis, which were important to clinical operation.

Objective To discuss clinical effects of transurethral electrovaporization of the prostate(TUVP) for the treatment of large benign prostatic hyperplasia(BPH).Methods A total of 126 cases of large BPH were treated with TUVP.Two longitudinal trenches were made at the position of 6 and 12 o'clock,respectively.Then the lateral lobe was retrogradely dissected from the proximal end of the seminal colliculus and was removed.Results The international prostate symptom scores(IPSS) decreased from 28.6?4.5 preoperatively to 10.7?2.6 postoperatively(t=38.661,P=0.000);the quality-of-life scores(QOL) decreased from 5.3?0.7 preoperatively to(2.0?)0.5 postoperatively(t=43.061,P=0.000);the maximum urinary flow rate(Qmax) increased from 5.7?3.6 ml/s preoperatively to 18.2?4.2 ml/s postoperatively(t=-25.365,P=0.000);the resident urine(RU) decreased from 312.4?56.6 ml preoperatively to 32.8?9.2 ml postoperatively(t=54.732,P=0.000).There were significant differences in all these parameters between preoperatively and postoperatively.Threatened transurethral resection syndrome(TURS) occurred during operation in 2 cases.Postoperatively,transient urinary incontinence was observed in 5 cases.Conclusions Transurethral electrovaporization of the prostate for the treatment of large BPH is effective and safe.

ObjectiveTo investigate the effects of electroacupuncture in Guanyuan(Ren4) and Zhongji(Ren3) on the functions of neurogenic bladder in patients with spinal cord injury(SCI) with the standard urodynamic measure.Methods15 patients with neurogenic bladder after SCI were included into the study.During urodynamic measure,they accepted electroacupuncture in Guanyuan(Ren4) and Zhongji(Ren3).The changes of the bladder storage volume(VH2O),bladder pressure(Pves),detrusor pressure(Pdet) and bladder compliance(BC) before and after electroacupuncture were recorded.ResultsThe patients' VH2O increased from(124.00±77.37) ml to(144.47±85.87) ml(P<0.01),Pves decreased from(65.33±23.90) cmH2O to(55.27±17.52) cmH2O(P<0.05),Pdet decreased from(52.87±18.68) cmH2O to(44.93±15.82) cmH2O(P<0.05)and BC increased from(2.35±2.05) ml/cmH2O to(3.48±3.04) ml/cmH2O(P<0.01).ConclusionElectroacupuncture is effective on neurogenic bladder recovery in patients with SCI.

Objective:To observe the effects of mycobacterium tuberculosis components (mannose-capped lipoarabinomannan,ManLAM) on the maturation of dendritic cells and downstream immunity.Methods:The peripheral blood mononuclear cells were obtained from healthy individuals,and then were cultured in medium with GM-CSF and IL-4.Five days later the medium was changed and cytokine was added to.On the sixth day,the cells were divided into three groups.Meanwhile ManLAM and LPS were added to stimulate the DCs according to the experimental design.Seven days later,the cells were collected and the level of DC-SIGN,HLA-DR,CD86 and CD83 were detected by flow cytometry.The levels of IL-12 and IL-10 in the supernatant were measured by enzyme-linked immunosorbent assay (ELISA).Proliferative induction of DCs to CD4+T lymphocytes was measured by mixed lymphocyte reaction(MLR).The naive CD4+CD45RA+ T cells and allogeneic DCs were co-cultured for 48 hours.Subsequently,the supernatant IFN-? level in each group was measured by ELISA.Results:(1)The expression of CD86 and CD83 on DCs in ManLAM group was lower than those of the mature group (P

Objective To explore the epidemiological characteristics of adult allergic diseases,looking for risk factors of allergic airway disease in Shiqi District of Zhangshan,and to provide a scientific basis for the development of community health education.Methods The questionnaire which was designed by national respiratory allergic diseases research and epidemiological survey collaboration group was carried out,and the random cluster sampling method was used to extract a total of 2 000 adults from Shiqi District of Zhongshan City,and the questionnaires,physi calexamination,and laboratory tests were taken.Results In Shiqi District of Zhongshan,the incidence rate of adult respiratory allergic disease was 10.4％,including allergic rhinitis,allergic pharyngitis and allergic asthma,accounted for 54.33％,33.65％ and 12.02％.Most common cause is smoking and keeping pets.Among respiratory allergic disease population,smoking accounted for 28％ and keep pets accounted for 17.8％.Common allergens are mites,cockroaches,animal fur and flowers.Leather pilot assassination test positive rate of respiratory allergic disease population was 37.50％,including mites,cockroach accounted for 23.08％,7.21％ of animal fur,flowers accounted for 6.25％.Conclusion In Shiqi District of Zhongshan,adult respiratory allergic disease prevalence is same as the country,the majority is respiratory diseases.The most common cause is smoking and keeping pets.The most common allergens are mites,cockroaches,animal fur and flowers.The incidence maybe related to life behavior and the living environment.

0.05). Conclusion Lentivirus-mediated RNAi of DC-SIGN gene suppresses the gene expression on the surface of DCs effectively,but had no effect on the maturity and functions of DCs.

ObjectiveTo analyze the feature of the urinary tract infection of female patients with spinal cord injury(SCI). Methods57 female SCI patients were reviewed.Results47 of 57 patients were identified with urinary tract infection(82.5%). Infecting micro organisms were mainly colonized with E.Coli (70.2%) and Klebsiella. ConclusionsUrinary tract infections in females have special feature in urethral colonization.
