In order to explore the available sero-diagnotic method for surveillance in basically controlled and controlled areas of schistosomiasis japonica, a 3 years longitudinal investigation of children 6~14 years old with COPT in 5 endemic areas was carried out after being basically controlled for 8~16 years. The results showed that the examination of children with COPT is one of the available serodiagnostic methods of schistosomiasis for surveillance. In all five areas the positive rate of children in this age group was less than 3%, and the circumoval precipitin rate among the positive cases was less than 5%. Therefore, it is indicated that the above mentioned two indexes can be used for sero-surveillance of schistosomiasis japonica.

Objective To investigate the postoperative changes of serum proteins and immune responses in critical patients and the effect of recombinant human growth hormone(rhGH).Method 45 critical patients were divided randomly into rhGH group (15 cases) and control group (30 cases) after operation. Patients in rhGH group were given rhGH 8*!U/d,im for 7 days starting 48 hours post operation. Result The postoperative level of serum transferin,albumin and prealbumin decreased in all patients, and so did the activity of CD 3,CD 4 ,CD 8,NK and the ratio of CD 4/CD 8 .Serum prealbumin level increased significantly in rhGH group at day 4 and after ( P

A survey was made in Chongqing Medical University on the cultural qualities of teachers of basic courses,their humanity and social knowledge,as well as the role these things have played in students' quality education.The analysis has showed that the cultural qualities of the teachers have been improved in the recent years,while there was still a gap from the requirements of cultivating students' cultural qualities.The survey suggests that it require great attention and constant efforts to improve the teachers' cultural qualities.

Objective To explore a new surgical method for the treatment of refractory fistula after breast augmentation and to improve patients healing efficiently.Methods This paper had collected two groups,a total of 178 cases of injected breast augmentation,who had shown the polyacrylamide hydrogel(PAAG)mixture shift,and caused abdominal fistula.Among them,89 cases further adopt new design in the treatment of fistula by using breast muscle membrane tissue flap and improve the effect of fistula treatment after the removal of fistula.And the other 89 cases were token the pure clean the cavity away caused by the abnormal material shift into the chest and abdominal wall.Results It was observed that PAAG widely distributed in the chest and abdominal wall and formatted the fistula connected mammary gland,axillary,chest abdominal wall.The area of lesions lacuna shrink by 80％ for the group used tissue flap after 2 weeks,but those not with tissue flap shrink by 45％(P＜0.01).At 4th week,all the patients of flap group achieved tissue healed,while the completely heal ratio of control group was only 73％.Compared two groups of healing rate,the group with tissue flap was obviously better than ones only with surgical method.Conclusion It suggests that main reasons for the liquidity bag and huge cavity are PAAG mixture shift into thoracic and abdominal wall and formed chronic fistula and connected the chest and abdominal wall.Local muscle membrane tissue flap can obviously promote the chest and abdominal wall fistula healing.

ObjectiveTo investigate the impacts of sepsis-induced cardiac dysfunction on hemodynamics, organ function and prognosis in the patients with septic shock.Methods A prospective cohort study was conducted in 44 patients suffering from septic shock with the duration< 24 hours admitted to the Department of Critical Care Medicine of Peking University Third Hospital during June 2013 to June 2014. The patients were divided into two groups according to the left ventricular ejection fraction (LVEF) as recorded in echocardiogram at time of admission to the intensive care unit (ICU) as sepsis-induced myocardial dysfunction group (LVEF< 0.50,n= 11) and normal cardiac function group (LVEF≥0.50,n= 33). The cardiac function evaluation and hemodynamics monitoring were performed with echocardiogram and pulse-induced contour cardiac output (PiCCO) on 1, 3, 7 days after the ICU admission. The plasma levels of the biomarkers of myocardial damage, troponin T (TnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured, and the parameters representing organ function and the 28-day prognosis were collected as well.Results On the ICU admission, central venous pressure (CVP) and left ventricular end-diastolic diameter (LVEDD) were obviously lower in normal cardiac function group than those of myocardial dysfunction group [CVP (mmHg, 1 mmHg = 0.133 kPa): 10±4 vs. 14±6,P< 0.05; LVEDD (mm): 45.0±5.3 vs. 51.8±7.1,P< 0.01], and there was no significant difference in other hemodynamic parameters between two groups. On the 3rd day, all the cardiac function and hemodynamic parameters showed no significant differences between the two groups. On the 7th day, the cardiac index (CI) and pulmonary vascular permeability index (PVPI) of normal cardiac function group were significantly higher than those of myocardial dysfunction group [CI (mL·s-1·m-2): 63.3±13.3 vs. 48.3±10.0,P< 0.05;PVPI: 1.5 (1.4, 1.9) vs. 1.1 (0.7, 1.1),P< 0.01], and no significant difference was found in the other parameters. The plasma levels of TnT and NT-proBNP were found to have no difference at three time points between two groups. There was no difference in the number or the extent of organ dysfunction, including lung, kidney, liver and coagulation system, between the groups at the time of ICU admission. There was no obvious difference in the 28-day survival rate between the myocardial dysfunction group and normal cardiac function group [81.8% (9/11) vs. 72.7% (24/33),χ2= 0.398, P= 0.528].Conclusions Sepsis-induced myocardial dysfunction is a reversible organ dysfunction. It can directly induce decreased left ventricular systolic function and enlargement of ventricle in patients with septic shock without reducing cardiac output or impairing the functions of other organs, or elevating the mortality rate.

Objective To characterize social-perceptual component and social-cognitive component of theory of mind(TOM) in patients with Parkinson's disease.Methods A total of 19 patients with idiopathic PD and 20 demographic-matched health subjects were included in this study.They were assessed by using Reading the Mind in the Eyes and Faux Pas task involving ToM socialperceptual component and social-cognitive component.The severity of PD was assessed by the Hoehn and Yahr scale.Results Significant difference was found between PD group and health controls in task involving ToM social-perceptual component (mind Reading:17.1 ± 3.1 vs.30.4 ± 1.7,F =278.756,P＜ 0.001),test involving social-cognitive component (Faux Pas Questions:29.0 ± 4.0 vs.41.2±4.4,F=81.647,P＜0.001).While the ability to identify sex and control questions of the Faux Pas showed no significant difference as compared to health controls group (F=3.508,P=0.069;F=1.063,P =0.309).Conclusions The ToM social-perceptual component and social-cognitive component are both impaired in patients with Parkinson's disease.

BACKGROUND: Frenulum of prepuce of penis contained many nerve terminals is an extremely sensitive region. If the frenulum is injured in circumcision or other operations, the complication, such as postoperative spontaneous pain of penis, sexual disturbance and so on, will occur. But there still is no define explanation for this up to now.OBJECTIVE: To observe the distribution of immunoreactive nerve terminal of calcitonin gene-related peptide (CGRP) in prepuce of penis and frenulum of prepuce of adult SD rats, and look for the source of CGRP immunoreactive nerve terminal in frenulum of prepuce.DESIGN: A single sample trial.SETTING:Department of Anatomy, School of Medicine, Zhejiang University.MATERIALS: The experiment was performed at Department of Anatomy,School of Medicine. Zhejiang University from September 2004 to May 2005. A total of 20 adult male SD rats were selected, and were raised in warm, quiet, photophygous environment for 1 week before the trial so as to make the rats fit for the environment and maintain their basal state.METHODS: The rats were assigned randomly into 2 groups. Ten rats in the first group were treated with the immunohistochemical method to observe the distribution of CGRP immunoreactive nerve terminal in prepuce of penis and frenulum of prepuce of adult rats. Ten rats in the second group were treated with fluorogold (FG) retrograde labeled combined with CGRP immunofluorescence labeled method to look for the source of CGRP immunoreactive nerve terminal in frenulum of prepuce of penis. MAIN OUTCOME MEASURES: ①The morphology and distribution of CGRP immunoreactive nerve terminal in prepuee of penis and frenulum of prepuce of adult SD rats were observed under light microscope. ②The distributive density and difference of CGRP immunoreactive nerve terminal in prepuce of penis and frenulum of prepuce were detected and compared (represented by A). ③Morphology and distribution of FG retrograde labeled -positive, CGRP single-labeled positive and FG/CGRP double-labeled positive neurons in dorsal root ganglion were observe under fluorescence microscope. ④Mean quantity of FG retrograde labeled positive, CGRP single abeled positive and FG/CGRP double-labeled positive neurons in dorsal root ganglion was counted.RESULTS: Totally 20 rats were involved in the analysis of results. ① Amber-coloured CGRP immunoreactive nerve terminal appeared in prepuce of penis and frenulum of prepuce of adult rats. These nerve terminal mainly occurred in basal layer of epidermis and papillary layer of dermis, distributed as twig shape or intestiniform; mostly of them were bundled, different in length, and some of them showed enlarged nodosity. ②The distributive density of CGRP immunoreactive nerve terminal in frenulum of prepuce of penis was significantly larger than that in prepuce of penis (2.15±0.32, 1.02±0.22,t =-2.03,P＜0.01). ③Combined with the FG retrograde labeled method it was found that these nerve terminal was derived from neurons of dorsal root ganglion opposed to the sixth lumbar spinal cord and the neurons of dorsal root ganglion opposed to the first acral spinal cord. FG retrograde labeled positive neurons differed in length. The cell body showed round or orbicular-ovate, without obvious prominence. Bright inaurate fine particle appeared in cytoplasm, no label in nucleus. Most cells arranged in line along nerve tract or diffusedly distributed. Most CGRP single-labeled positive neurons were middle or small cells found by CGRP immunofluorescence labeling. Dyeing was too dark.Reaction product distributed evenly in cytoplasm, which showed bright dark green (FITC labeled color). The same positive section was observed comparatively under different excitation light. It was found that FG/CGRP double-labeled positive cells were middle or small, and its amount accounted for a half of the total number of FG retrograde positive cells.CONCLUSION: CGRP may participate the transmission of sensory information in prepuce of penis and frenulum of prepuce of rats. The CGRP immunoreactive nerve terminal in frenulum of prepuce of penis of rats is sourced from neurons of dorsal root ganglion opposed to the sixth lumbar spinal cord and the neurons of dorsal root ganglion opposed to the first sacral spinal cord.

ObjectiveTo determine the effects of perioperative hemodynamic goal directed therapy (GDT) on postoperative infection rates. MethodsWe conducted a systematic review and Meta-analysis.MEDLINE,the Cochrane Library,EMBASE,CNKI and other sources were searched until March 2011.All randomized controlled trials (RCTs) on adult major surgical patients managed with perioperative GDT or according to routine haemodynamic practice were included.Primary outcome measure was specific for type of infection. Two authors independently extracted data and assessed study quality using standardized instruments; Consensus was reached by conference.The Cochrance Collaboration's software RevMan 5.0 was used for data analysis. ResultsSixteen studies were included in the final analysis,providing a sample of 3309 patients. Perioperative GDT significantly reduced surgical site infections (SSI)(OR =0.60; 95％CI0.46-0.74; P ＜0.0001),pneumonia (OR =0.69; 95％CI 0.53 -0.90;P =0.007),and urinary tract infections (UTIs) (OR =0.44; 95％ CI 0.22 -0.88; P =0.02),and there was no heterogeneity between studies (P ＞ 0.1,I2 ＜ 50％ ).A significant decrease in total infection episodes was observed (OR=0.37; 95％CI0.22-0.61; P＜0.00001). ConclusionsA flow-directed hemodynamic therapy protects the high-risk surgical patients against postoperative hospital-acquired infections.

OBJECTIVE To study the isolation status and antimicrobial resistance of nonfermenting Gram-negative bacilli collected from intensive care unit(ICU) of our hospital so as to instruct the rational clinical application of antibiotics.METHODS The antimicrobial resistance of nonfermenting Gram-negative bacilli isolates collected from patients in ICU from Jan 2003 to Dec 2007 was analyzed.Antimicrobial susceptibility of clinical isolates were tested by Kirby-Bauer method.RESULTS Total 384 nonfermenting Gram-negative bacilli isolates were collected in 5 years.The most common species were Acinetobacter baumannii(219),Pseudomonas aeruginosa(117) and Stenotrophomonas maltophilla(36).The antimicrobial resistance rate of nonfermenting Gram-negative bacterial to most antibiotics were much higher.The antimicrobial resistance rate of Acinetobacter spp to imipenem,cefoperazone/sulbactam and piperacillin/tazobactam was 3.7%,28.3% and 42.9%.But the resistance rate of Acinetobacter spp to imipenem was increased in recent 2 years(58.0%).The antimicrobial resistance rate of P.aeruginosa to cefoperazone/sulbactam was the lowest.That of imipenem-resistant P.aeruginosa to cefoperazone/sulbactam was 34.0%.S.maltophilla was relatively susceptible to ceftazidime,cefoperazone/sulbactam and piperacillin/tazobactam.CONCLUSIONS Nonfermenters Gram-negative bacilli are the important pathogens in ICU.Surveillance of their prevalence and drug resistance may provide evidences for rational antibiotic choices.

OBJECTIVE To investigate the distribution and drug resistance of nosocomial infection pathogens.METHODS The data of pathogen′s origin and antibacterial resistance of Intensive Care Unit(ICU) inpatients from Apr 2008 to Mar 2009 in a Hospital were analyzed.RESULTS There were 226 strains pathogens isolated from 116 nosocomial infection cases,from which the Gram-negative bacteria were predominate(63.27%).The resistance rates of Acinetobacter baumannii was the highest in Gram-negative bacteria,more than 70% isolates resistant to almost antibacterial.The main Gram-positive bacteria were Staphylococcus aureus,and the rate of meticillin-resistant S.aureus(MRSA) was 41.3%.All S.aureus were sensitive to vancomycin and Linezolid.CONCLUSIONS To control the antibacterial resistance of pathogens and decrease the nosocomial infection,it is important to strengthen the appropriate use of antibiotics.
