Objective To evaluate the effect of pituitrin and nursing for patients with vasoplegic syndrome after cardiopulmonary bypass. Methods 38 patients with cardiopulmonary bypass after open heart operation were divided into two groups with 19 cases in each group according to odd-nunbered and even-numbered days, the PT group was given pituitrin treatment, the NE group was given norepinephrine treatment. Heart rate, MAP, urine volume were recorded at 0.5, 1, 2, 6, 12 and 24 hours after drug therapy.Mechanical ventilation time, ICU stay time,hepatic and renal function and clinical symptom were compared between the two groups. Results MAP and urine volume increased significantly at 0.5 hour after pituitrin therapy. MAP increased from (55.33±4.10)mmHg to (67.34±4.13)mmHg. Urine volume increased from (0.08±0.02)ml·kg-1·h-1 to (1.84±1.21)ml·kg-1 ·h-1 MAP and urine volume also increased at other time points. In the NE group, MAP increased at 1h after treatment. Both MAP and urine volume increased at 2h and later after norepinephrine treatment. One death happened in the NE group. Compared with the NE group, the PT group was associated with lower ICU stay, mechanical ventilation time and 24h serum LAC.Liver and kidney function, myocardial infarction, nausea and vomiting, and other side effects were not different between the two groups. Conclusions Application of low-dosage pituitrin is rapid, efficient and safe treatment for patients with vasoplegic syndrome after open heart operation.

0.05),indicating that two groups had the similar effect on relieving pain.VAS score in both groups was markedly decreased after treatment(P0.05).Conclusion Acupuncture is effective in the treatment of lumbodorsal myofascial pain syndrome,and its effect is similar to that of local block of trigger points with lidocaine.Acupuncture has less side effect.

Objective To understand the clinical features of primary Sjgren′s syndrome (pSS) in both sex,thus to improve the level of diagnosis and treatment.Methods Clinical data of 77 cases of pSS were collected and analyzed.Results No significant difference was found between male and female in mean age of onset and average disease duration at the time of diagnosis.Patients with dry mouth/eye as a complaint for seeing a doctor accounted for only less than a half;whereas,hyper ? globulinemia existed in more than 90% of the patients.The onset symptom in male was more different from female.Dry mouth/eye,arthralgia,pulmonary manifestations,renal tubular acidosis,and dermatic manifestations were the frequent presentations.Dry mouth/eye presented latter,uncommon,and milder in male than in female.However,no difference was found between male and female in the incidence of salivary gland involvement.Pulmonary symptoms presented earlier,and the incidence of pulmonary fibrosis was higher in male than in female.Whereas,the pulmonary symptom occurred earlier in male patients,and the incidence of pulmonary interstitial fibrosis was higher in male than in female.The incidence of positive RF and anti SSA/SSB antibody was significantly lower in male than in female.Conclusion Primary Sjgren′s syndrome is one of the systemic immune diseases.It′s clinical manifestations were diverse.Less than a half of patients see a doctor because of dry mouth/eye.There are many differences between male and female patients in clinical presentations;and the incidence of positive auto antibodies is lower in male patients than in female.

Objective To observe the therapeutic effect of Jin’s three-needle therapy plus medicated thread moxibustion for shoulder-hand syndrome at phaseⅠ. Methods By simple randomized controlled method, sixty qualified patients were randomized into observation group (N=32) and control group (N=28) . The observation group was given Jin’s three-needle therapy plus medicated thread moxibustion, and the control group was given conventional acupuncture therapy. Treatment was performed once a day for the two groups, 5 continuous times per week, and one course covered 3 weeks. At the end of the treatment, therapeutic effect, simplified Fugl-Meyer scores for upper limb motor ability, and pain visual analog scale ( VAS) scores were compared between the two groups. Results (1) The total effective rate was 93.7% in the observation group and was 82.1% in the control group, the difference being significant ( P<0.05). ( 2) Fugl-Meyer scores were improved in the two groups after treatment (P<0.05 or P<0.01), and the improvement of the observation group was superior to that of the control group ( P<0.05). ( 3) The results of VAS scoring showed that the pain in the upper limb was much relieved in both groups after treatment ( P<0.05 or P<0.01) , and the relief of pain was more obvious in the observation group ( P<0.05). Conclusion Jin’s three-needle therapy plus medicated thread moxibustion exerts certain therapeutic effect for shoulder-hand syndrome at phaseⅠ.

BACKGROUND: The data of epidemiological survey on rheumatic diseases such as ankylosing spondylitis (AS) are very rare in China, especially in Shenzhen. The comprehensive understanding of epidemiological situation of AS in Shenzhen can be used to draw up treatment plans by Shenzhen Health Bureau and some other health organizations.OBJECTIVE: To investigate the epidemiological features of AS.DESIGN: Randomized complete collection and cross-sectional investigation.SETTING: Shenzhen Rheumatism Institute of Guangdong Medical College. PARTICIPANTS: From December 2001 to April 2004, totally 6 684 adults aged over 16 years were selected from three regions (one region of river and lakes, one local mountain region and one inhabitant region) of Shenzhen. Among them, 5 922 adults (2 659 males and 3 263 female) were actually investigated and the investigative rate was 88.6%. Males were accounted for 44.9% and females were 55.1%, and the ratio was 1:1.23.METHODS: Step 1 and 2, the investigated individuals were questioned and their answers were recorded by the investigators. The questionnaire proceeded one by one for every individual and proceeded at homes. Step 3,the individuals with positive findings at steps 1 and 2 were examined by rheumatologic doctors. Step 4, individuals with suspected AS were subjected to human leukocyte antigen B27 (HLA-B27) assays, radiographies including plain pelvic films, plain lumbar-vertebral films and if necessary, radiographies at other areas of spinal column as well as peripheral joints.MAIN OUTCOME MEASURES: Frequencies of rheumatic complaints,prevalence rate of AS, positive frequencies of hum an HLA-B27, and comparisons with relevant data abroad.RESULTS: ① General frequency of rheumatism was 21.6%, and the highest complaint was at knee joint, then at waist, shoulder, neck and hand. In female, the frequencies of complaints at every joint mentioned above were higher than those in male (P ＜ 0.05). A total of 13 patients (4.7%) had to discontinue their work because of rheumatic diseases. ②Prevalence rate of AS was accounted for 0.37%, and the ratio between male and female was 4.5: 1. The onset of AS began at middle age in majority patients. ③ Positive frequency of HLA-B27 was 5.0%. ④ Rate of misdiagnosis, the rate of early diagnosis and the rate of long-term irrational drug-usage were 64%, 27% and 73%, respectively.CONCLUSION: In Shenzhen, the prevalence rate of AS (0.37%) is ranked higher than that in Beijing (0.26%), Shantou (0.26%), America(0.20%) and the whites of Greece (0.24%). The differences among them may be connected with the fact that in Shenzhen the young people occupy a large proportion of population.

Objective:To study the cytotoxic effects on three glioma cell lines U343, U138, U373 induced by anti-human DR5/DR4 monoclonal antibodies(FMU1.5/FMU1.4) and the underlying mechanism.Methods:Expression of DR4/DR5 was quantitated by flow cytometry and DR/4DR5 mRNA detected by RT-PCR. Cytotoxicity exerted by FMU1.4/FMU1.5 on three cell lines was measured by MTT colorimetry and the induced apoptosis was determined by agarose gel electrophoresis, DNA ploidy analysis was studied by flow cytometry.Results:The expression of DR5 on U343 cells was higher and the expression of DR4 on U373 cells was lower. Cell line U343 was sensitive to FMU1.5 and in a dose dependent manner, but it was partially sensitive to FMU1.4; Cell line U138 was partially sensitive to FMU1.5 and resistant to FMU1.4; Cell line U373 was insensitive to two antibodies.Conclusion:Apoptosis induced by monoclonal antibodie FMU1.4/FMU1.5 vary among three cell lines. The underlying mechanism may be relevant to DR4/DR5 expression,the release of cytochrome C and FLIP.

Objective The health risk behaviors of undergraduates exist universally, which can induce other social problems. The aim of this study was to describe the present situation and analyze the influencing factors of health risk behaviors of 404 undergradu-ates. Methods Adolescent Health Related Behaviors Questionnaires were conducted in 404 undergraduates chosen from a University in Nantong by stratified cluster sampling method.Logistic regression and multiplicative interactive effects were adopted to analyze the influ-encing factors. Results Health risk behaviors were common among college students.In the past 30 days, 33.4%of students had rule-breaking behaviors in bicycle riding and 45.3%had rule breaking behaviors in walking.In the past 12 months, 2.7%of students had in-tentionally hurt themselves, 2.5%had suicidal inclination, 19.8%had smoking history, 69.3%had drinking history, 7.4%participa-ted in the gambling, 7.7%and 11.9%played video games and surfed online over 4 hours everyday, respectively, and 4.5%of students have had sex.In the past 30 days, 94.3% of students lost their weight through the unhealthy way, and 37.8%of students participated physi-cal exercise over 60 minutes for at least 3 days in the past 7 days.Lo-gistic regression indicated that male, higher grade and higher education level of the student′s mother were the risk factors of some health risk behaviors.Interactive effect was not found between the different influencing factors. Conclusion Health risk behaviors exist widely a-mong college students and more attention should be paid to risk behaviors of college students.Health behaviors should be trained among adolescents to improve their overall health level.

Objective: To investigate the inhibitory effects and mechanism of a novel anti-human DR5 ( death receptor 5 of TRAIL) monoclonal antibody to glioma cell lines U343. Methods: DR5 protein was tested quantitative through FCM: DR5 mRNA was observed through RT-PCR and distribution was tested by immunocytochemistry.
