ystolic LS and RS are equal in the indentification of the infarcted segments.

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 explore the effect of double cypress powder (DCP) combined with TDP irradiation on lumbar intervertebral disc protrusion and summarize nursing experience.Methods One hundred and twenty-five patients with lumbar intervertebral disc protrusion were randomized into the observation group and control group.The control group was treated with massage and electro-acupuncture and the observation group received DCP fumigation combined with TDP irradiation besides treatments the controls received.The two groups were compared in terms of pain level and curative effect after two courses of treatment.Result The score on pains by VAS in the treatment group was significantly lower than that in the control group and the curative effect was better than that in the control group (P<0.05).Conclusion On the basis of the massage,electro-acupuncture and moxibustion therapy,DCP combined with TDP irradiation is therapeutically effective in the reduction of the pains from lumbar disc protrusion.

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 evaluate the actual displacement of a femoral neck fracture following close reduction under the C-arm X-ray perspective.Methods From June, 2006 to June, 2009, we managed 12 patients with femoral neck fracture by open reduction and internal fixation.They were 8 males and 4 females, aged from 23 to 65 (average, 42.3) years old.We tried close reduction of their fractures under the C-arm X-ray perspective before a temporary fixation.Next we performed open reduction, readjusted the fracture ends, and placed internal fixation.The actual displacement of the fracture measured after open reduction was carefully compared with the close reduction under the X-ray perspective.Results A substantial displacement was found after open reduction in 7 patients who had achieved anatomic reduction under the X-ray perspective.In the other 5 patients who presented with a slight displacement after close reduction under X-ray perspective, the actual displacements were larger than the X-ray observations but completely reduced after open reduction.The actual measurements after open reduction were significantly larger (3.21 ± 0.96 mm on average) in the anteroposterior displacement ( t = 11.540, P = 0.000), but insignificantly larger (0.58 ±0.93 mm on average) in the superior-inferior displacement ( t = 2.184, P = 0.346) than those after close reduction.Conclusions In general, anatomic reduction can not be achieved for a femoral neck fracture under the C-arm X-ray perspective.Consequently, open reduction may be better than close reduction in the treatment of femoral neck fracture in that improper reduction can block blood supply to the femoral neck and dissection of the capsula articularis coxae can improve blood supply as well as help decompression.

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 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.
