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.

The study assessed the early functional outcomes with cemented titanium implants of radius in the treatment of comminuted fractures of radial heads. The functional outcomes of arthroplasty with cemented titanium implants of radius in the treatment of radial head fractures (Mason Type III: 6; Mason Type IV: 4) in 10 consecutive patients (mean age, 38 years) were evaluated over a mean time of 23.7 months (18-31 months). The patients were assessed on the basis of physical examination, functional rating (Mayo) and radiographic findings. The parameters evaluated included motion, stability, pain, and grip strength. Five patients were considered to have excellent results, 4 patients had good results and 1 patient had fairly good results. There were no cases of infection, prosthetic failure, heterotopic ossification or dislocation. When medial collateral ligament was injured, radial head became the main stabilizing structure of the elbow. Titanium radial head implant may provide the stability similar to that of native radial head. We believe that titanium radial head implants may be indicated for the Mason Type III and Mason Type IV radial head fractures.

Acute ischemic stroke has become one of the important causes of death and disability in human beings, especially in elderly patients. Intravenous thrombolysis with alteplase is an important treatment. However, there are many underlying diseases and poor overall conditions in elderly patients, which increase the risk of intracranial hemorrhage. Intracranial hemorrhage transformation makes the patient′s condition worse, which is the most serious complication of alteplase intravenous thrombolysis, and also one of the important reasons for the low treatment rate of alteplase intravenous thrombolysis in elderly patients. Therefore, we need to pay close attention to the occurrence mechanism and risk factors of intracranial hemorrhage transformation after alteplase intravenous thrombolysis in elderly patients, so as to reduce the risk of intracranial hemorrhage transformation, improve the prognosis and reduce the risk of morbidity and mortality.

OBJECTIVE:To observe the efficacy of urapidil hydrochloride in control of blood pressure at the perioperative stage of hemorrhagic apoplexy.METHODS:All80patients with hypertensive cerebral hemorrhage were managed with seda?tive,dehydration,hemostasis,and cerebral nerve nourishment,then when the blood pressure still remained high,or the blood pressure was hard to control after the intubation,urapidi hydrochloride was administered by intravenous infusion at the dose of250mg added with250ml of5%glucose infusion,the infusion drip was set at constant speed,with2mg/min as its starting speed,while at the same time the blood pressure and heart rate were monitored and infusion speed was adjusted every10to15min,after the target blood pressure21.2/13.2kPa was obtained,the infusion speed was kept at0.1～0.4mg/min.The blood pressure and heart rate were observed separately before the administration of urapidil hydrochloride and2,5,10,15,20and30min after the administration as well as after the operation.RESULTS:5min after the administration,blood pres?sure decreased remarkably but not to the extent to cause low blood pressure,and the heart rate increased slightly at the same time,generally not over10beats each minute.CONCLUSION:Urapidil hydrochloride decreases blood pressure steadily and safely at a manageable dosage.It can be used to control blood pressure during hemostasis and clearance of hematoma,which reduces the possibility of rehemorrhagia caused by high blood pressure during and after the operation.
