Objective To explore the relevance between resting heart rate (RHR) and metabolic syndrome in young and middle-aged patients with essential hypertension.Methods Three hundred and forty patients with essential hypertension were enrolled in this study.According to the RHR,the hypertension patients were categorized into 3 groups:group RHR 1 (RHR ＜ 70 bpm,52 cases),group RHR 2(RHR 70-85 bpm,168 cases) and group RHR 3 (RHR ＞ 85 bpm,120 cases).The RHR,blood pressure,fasting blood glucose,triglyceride,high density lipoprotein cholesterol,2 h postprandial blood glucose and waistline were determined and compared.Results The level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure,diastolic pressure,and high density lipoprotein cholesterol in group RHR 1 were (4.96 ± 0.65) mmol/L,(6.85 ± 0.51) mmol/L,(1.69 ± 0.43) mmol/L,(78.3 ± 6.5) cm,(143.2 ± 5.6) mmHg (1 mmHg=0.133 kPa),(85.4 ±5.2) mmHg and (1.08 ±0.64) mmol/L.In group RHR 2 they were (5.66 ± 0.77) mmol/L,(7.94 ± 0.66) mmol/L,(2.58 ± 0.75) mmol/L,(88.6 ± 7.3) cm,(156.7 ± 6.1) mmHg,(93.6 ± 4.7) mmHg,and (0.95 ± 0.59) mmol/L.In group RHR 3 they were (6.85 ± 0.73) mmol/L,(8.97 ± 0.59) mmo]/L,(3.52 ± 0.90) mmol/L,(95.8 ± 9.2) cm,(164.3 ± 7.4) mmHg,(101.2 ± 3.5) mmHg and (0.78 ± 0.33) mmol/L.With the increase of RHR,the level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure and diastolic pressure increased step by step,high density lipoprotein cholesterol decreased step by step,and there were significant differences (P ＜ 0.05).Correlation analysis showed that RHR was positively correlated with fasting blood glucose,2 h postprandia blood glucose,triglyceride and waistline (r =0.52,0.45,0.50,0.36,P ＜ 0.05),and negatively correlated with high density lipoprotein cholesterol(r =-0.39,P ＜ 0.05).Conclusion RHR is closely related to the metabolic disorder in young and middle-aged patients with essential hypertension,and doctors should pay attention to the heart rate control while lowering blood pressure.

Pulmonary embolism(PE)is a relatively common cardiovascular emergency.Haemodynamic instability is the characteristics of massive pulmonary embolism,with a mortality as high as 20%.The goals of PE treatment are to remove the thromboembolic obstruction rapidly,exert beneficial effects on haemodynamic parameters and save the lives of patients.Haemodynamic and respiratory support is of vital importance in some critically ill patients with PE.The basic treatment is anticoagulation,the methods of which are different for PE during pregnancy,among cancer patients,with right heart thrombi and with heparin-induced thrombocytopenia.

Objective To optimize the medium for rhizomatous induction of Belamcanda chinensis in vitro. Methods By plant tissue culture technology, the effects of various carbon source, NAA, and active carbon at different concentration on the rhizomatous formation of B. chinensis in vitro were studied. Results MS+6-BA 2.0 mg/L+NAA 0.5 mg/L+6% white sugar was the optimal medium for the rhiz-omatous formation of B. chinensis in vitro. Active carbon should not be added to the medium. The germination rate of rhizomatous in vitro was 61.03% on the MS + BA 2.0 mg/L+3% white sugar. Conclusion Sugar concentration is the main factor of the influence on the rhizomatous formation of B. chinensis in vitro.

Methods300 patients with coronary heart disease were randomly divided into the observation group and the control group with 150 cases in each group after admission. The observation group adopted diversified admission education, while the control group received simple education style, the satisfaction degree of both groups was compared. ResultsThe satisfac-tion degree of the observation group was higher than that of the control group. ConclusionsAdoption of di-versified admission education is beneficial to improve the satisfaction degree of patients, increase their cognition degree, thus make patients cooperate with treatment and nursing better and facilitate their rehabilitation.

Objective To discuss the application effects of trinitarian visualization teaching model in endoscopy reprocessing teaching practice. Methods Subjects in the study were divided into the trinitarian visualization teaching group (n=40) and the traditional teaching group (n=43) by random number table method; Compliance and credibility rating of endoscope reprocessing procedures were compared between 2 groups. 2 weeks after training, objectives were examined and assessed by questionnaires separately. Results Compliance of the trinitarian visualization teaching group was higher than the traditional teaching group (χ2=10.501, P=0.033). The trinitarian visualization teaching group had a higher rating in compliance, with 47.47 credibility points, theory test (93.79 ± 3.81) points and 93.02%(40/43) of operation pass. The traditional teaching group had a credibility point of 43.68 credibility points, with theory test (85.25±3.14) points and 77.50%(31/40) of operation pass. Significant difference between the two groups were statistical significant (t=4.84 and 11.097, χ2=4.038,P<0.01 or 0.05). Conclusions The trinitarian visualization teaching model can be used to improve the reprocessing training quality, to save time and human resource and to reach the training demand.

BACKGROUND:Studies have shown that human umbilical cord mesenchymal stem cel s can improve pulmonary ventilation function by reducing inflammations. OBJECTIVE:To observe the therapeutic effect of human umbilical cord mesenchymal stem cel transplantation on acute lung injury. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and experimental group. Rats in the latter two groups were used to establish animal models of acute lung injury by intratracheal instil ation of lipopolysaccharide. One hour after modeling, rats in the experimental group were intratracheal y administered human umbilical cord mesenchymal stem cel suspension (0.1 mL, 1×106 cel s), and those in the other two groups were given normal saline in the same dose intratracheal y. Twenty-four hours after treatment, the pathological changes of lung tissue were observed using hematoxylin-eosin staining;the wet and dry weight ratio of the lung tissue and the levels of serum interleukin-1 and interleukin-8 were detected. RESULTS AND CONCLUSION:Compared with the normal group, the wet and dry weight ratio of the lung tissue and the levels of serum interleukin-1 and interleukin-8 were significantly increased in the model group (P<0.05), while compared with the model group, these levels were significantly decreased in the experimental group (P<0.05). Hematoxylin-eosin staining results showed clear alveolar space structure with complete alveolar septum in the normal group. In the model group, the alveolar septum was markedly thickened, and there was visible pulmonary capil ary hyperemia, edema, as wel as a large amount of inflammatory cel infiltrations in the pulmonary capil aries and alveolar space. Edema fluid rich in proteins was observed in a part of the pulmonary alveoli, and an extensive transparent membrane formed in the alveolar space. In the experimental group, the alveolar structure was clear, but the alveolar septum became thickened, and red blood cel s and a smal amount of infiltrated inflammatory cel s were leaked from the pulmonary interstitial tissue. In conclusion, human umbilical cord mesenchymal stem cel transplantation for treatment of acute lung injury can reduce inflammatory factor levels and al eviate lung injury.

ObjectiveTo investigate the diagnosis and operative procedure for spontaneous perforation of congenital choledochal cyst in children. MethodsThe clinical data of 16 cases with spontaneous perforation of congenital choledochal cyst were analysed retrospectively.ResultsAll cases were under 4 years old with a mean age of 23 months. Abdominal distension, pain, vomiting, fever and diffuse tenderness were present in all patients. The preoperative diagnosis was established by paracentesis in ten patients. Abdominal sonography and CT found a cyst in 5 of the 10 cases reviewed. In 11 cases (68.7%), the site of perforation was found on the confluence of common bile duct and gallbladder cystic duct. T-tube drainage was used as a transition measure. All patients recovered uneventfully. Radical resection was performed in about three months after the initial operation. ConclusionsThe obstruction of the bile duct and poor blood supply to the choledochal cyst are major causes leading to perforation. Routine abdominal paracentesis should be carried out for a small child with peritonitis and general abdominal tenderness, especially on the right upper quadrant.T-tube drainage should be adopted as an emergent procedure to tide the patient over the crisis followed by elective choledochal cyst resection and bile duct reconstruction.

Objective To study the main influence factors of nosocomial infection(NI) and establish a model to predict and forecast the risk of NI on patients in hospitals. Methods Clinical data of 27352 inpatients extracted from hospital information system were sorted out and coded, and a logistic regression model about the probability of NI was established. The risk of NI was divided into four scales. Results With multiple factor analysis,16 risk factors of NI were identified, which were age, high body temperature, numbers of diagnosis, days of staying in hospital and seriousness, numbers of routine test for urine, times of blood transfusion, use or without use of antibiotic and radiotherapy, turning over the bodies or not, relationships between infection and interventional operations, with or without diabetes, categories of diseases based on ICD-9, numbers of interventional operations, type of anesthesia and department of admission. If NI was judged when predicted probability(Pr)of logistic regression model exceeded 0 35, the specificity and false diagnostic rate of diagnostic test were 0 995 and 0 005 respectively, and the area under ROC curve was 0 986. According to decision tree method, the risk of NI was classified into four degrees: low (Pr

Objective:To study the possible therapeutic mechanisms of triptergium wilfordi in treating glomerulonephritis.Methods:Thirty seven patients with IgA nephropathy were detected urine mononeuclear cells densities with flow cytometry during taking triptergium wilfordi tablets,30 healthy people were used as normal control.Results:The patients urine CD3 +?CD4 +?CD8 +?CD14 + and CD44 + cells densities were much higher than normal control's,but obviously decreased after triptergium wilfordi treatment.CD4/CD8 ratio was much lower in patients than in normal control.It increased markedly after treatment.Patients who reached remission initially had a lower CD4 + cell percentage and higher CD14 + cells percentage than those showed no response to triptergium wilfordi treatment.Conclusion:Triptergium wilfordi could modulate kidney immune cell function and adhesive molecule CD44 expression.Its effects were associated with renal immunity.
