Objective:To explore diagnostic value of dynamic electrocardiogram (DCG) combined esophageal electro‐physiological examination (EEE) for sick sinus syndrome (SSS) .Methods :A total of 74 cases suspecting SSS ,who presented 24h mean heart rate <55 beats/min in DCG ,were selected .After DCG examination ,all subjects received EEE . Diagnostic value of single and combined examinations wereexplored .Results:Compared withthe SSS positive rate of single DCG and single EEE(87.8% ,86.5% ) ,theSSS positive rate ofDCG combined EEE(97.3% ) was sig‐nificantly rose ,P<0.05 both .Conclusion:Dynamic electrocardiogram combined esophageal electrophysiological ex‐amination can evaluate sinus node function from different angles ,which can significantlyincrease SSS diagnose rat .

Objective To understand the status of the sanitary quality in some areas of countryside in Guangxi. Methods The investigation on the type of water source and the water supply was carried out in 9 counties.10 sampling points were established in each observed county.91 water samples were collected totally for the measurement of water quality ,then their sanitary quality was assessed based on the Criteria for Implementing the Hygienic Standards for Drinking Water in Countryside. Results In the observed 9 counties ,15.33% of total population drank water supplied with surface water,and 84.67% with ground water source. Drinking water from centralized water supply system was supplied to 43.16% of total population.In the centralized water supply system,the finished water completely treated by sedimentation and filtration was supplied to 10.57% of the total population,the disinfected finished water was only supplied to 2.96% of the total population,the raw water was directly supplied to 68.66% of the tap water-supplied population without any treatment.The completely-qualified rate of water samples was 20.88% for total 91 water samples,14.81% for surface water samples and 23.44% for ground water samples respectively.The qualified rate of bacterial indexes was 32.61% for water samples collected from centralized water supply system and 20.00% for those from decentralized water supply system. Conclusion Most of the peasants in the investigated 9 counties hadn't been supplied by safe and health drinking water.Contamination of drinking water by microorganisms was the main sanitary problem in water supply in countryside of Guangxi.

Objective Through application of clinical pathway in hospitalization patients undergoing uterectomy, we aimed to study the efficacy of clinical pathway in uterectomy patients. Methods 120 patients randomly sampled into the experimental group and the control group with 60 in each. The experimental group received diagnosis, treatment, nursing and rehabilitation according to the clinical pathway table, patients in the control group received routine nursing interventions. The average hospitalization days, medical costs, patient satisfaction degree, disease cognition, first exercise time after operation and medical disputes were compared between the two groups. Results The average hospitalization days and hospitalization costs of the experimental group were obviously lower than those in the control group, patients' satisfaction degree, knowledge of health and first functional exercise time in the experimental group were better than those of the control group, while the medical disputes in the experimental group were obviously de -creased in the experimental group. Conclusions Application of clinical pathway in nursing care for uterectomy patients can effectively decrease hospitalization days, medical costs and disputes. It is also helpful for patients to cooperate with doctors in diagnosis, treatment, nursing, thus increase the satisfaction degree of patients, ensure the reasonable use of medical resources and promote the sustainable improvement of nursing quality.

Objective To establish the determination method of baicalin in the children's YifeiPingchuan mixture by RP-HPLC.Methods A Kromasil C18 column was used with methanol-(0.4％)phosphoric acid-triethylamine (45 ∶ 55 ∶ 2 drops) as mobile phase with a column temperature of 28 ℃.The flow rate was 1.0 ml/min.The detection wavelength was set at 277 nm.Results The linear range of baicalin was 0.040～1.000 μg (r=0.9999) with a average recovery of 99.82 and RSD of 1.01％.Conclusion The method for quantification of baicalin was sensitive,accurate,and convenient,which can also be used as one of basis of quality standard for Yifei-Pingchuan mixture.

Objective To observe the efficacy of omidazole in the treatment of trichomonal vaginitis.Methods 64 cases with trichomonal vaginitis were divided into two groups randomly.The experiment group(32 cases) was given ornidazole,while the control group was given metronidazole.Changes in symptoms laboratory tests,vaginal examination and adverse reactions were compared between the two groups.Results The efficacy of experiment group was significantly better than the control group( P ＜ 0.05).The experiment group's adverse reactions were sigenificantly less than the control group ( P ＜ 0.05 ).Conclusiou Ornidazole used in the treatment of trichormonal vaginitis shows a significant effect with long duration and less adverse reactions,so it's should be promoted.

Objective To evaluate the effect of a bioartificial liver (BAL) system for treatment of acute liver failure (ALF) in canines and its relationship to serum endotoxin. Methods ALF was induced by end-side portocaval shunt combined with common bile duct ligation and transection. Ten ALF canines were distributed to BAL group (n=5), or to a control group (n=5). Each BAL circulation lasted 5h. Serum endotoxin, alanine aminotransferase (ALT) and total bilirubin (TB) before establishment of ALF model, pre-circulation and post-circulation were determined. Results Serum endotoxin level was 0.284 EU/ml, 0.526 EU/ml and 0.416 EU/ml before establishment of ALF model, and pre-circulation and post-circulation in BAL group, respectively. The serum endotoxin level in BAL group increased pre-circulation (P

The experimental right cerebral contusion model was established in rats.To observe the relationship between the expression of Nitric oxide synthase 1(NOS1)and time elapsed after cerebral contusion,the expression of Nitric oxide synthase 1(NOS1)and mRNA was studied by immunohistochemistry and in situ hybridization at different intervals after cerebral injury.The results indicated that a positive relationship existed between the expression of NOS1 and NOS1 mRNA and the intervals elapsed after brain injury.This method also can be used to distinguish antemortem and postmortem injury rat′s cerebral contusion.So that,the expression of NOS1 and NOS1 mRNA is of great value for timing of brain injury.
