One of the important therapeutic measures in the acute stage of cerebral hemorrhage is to treat cerebral edema and lower intracranial pressure. Mannitol, an osmotic dehydrant, is most widely used in clinical practice. Its major effects include the reduction of intracranial pressure and cerebral edema and prevention of cerebral herniation. Besides, mannitol scavenges oxygen free radicals and protects brain cells. So it has extremely important significance in reducing the mortality of intracerebral hemorrhage.

Objective To explore the feasibility of two-port laparoscopic drainage in the treatment of liver abscess. Methods A total of 18 patients with bacterial hepatic abscess underwent twoport laparoscopic drainage.Two incisions were made at the superior border of the umbilicus and 4～5 cm below the right costal margin near the anterior axillary line,respectively.The abscess was cut through in "┼" or "╫" shape.The pus cavity was debrided bluntly,and a double-lumen drainage tube was placed.Results The laparoscopic drainage was performed successfully in all the 18 patients.The operative duration was 30～75 min(mean,45 min).A bile leakage for 80～100 ml per day occurred in 1 patient.The drainage tube was removed on the 12th postoperative day and the patient was discharged from hospital on the 14th postoperative day.Of the 18 patients,the hospital stay after operation was 7～14 d(mean,8.5 d).All the patients were followed for 5～12 months(mean,9 months) and no residual abscess or recurrence was found. Conclusions Two-port laparoscopic drainage for liver abscess is an ideal approach with advantages of simple manipulation,slight contamination inside abdominal cavity,little trauma,low complication rates,and rapid recovery.

Objective To investigate the types of commonly used anti-hypertensive drugs and hypoglycemic drugs and treatment schemes to provide a basis for rationally treating hypertension complicating type 2 diabetes mellitus(T2DM).Methods The medication situation in 191 patients with hypertension complicating T2DM in our hospital were analyzed and investigated.The use of anti-hypertensive drugs and hypoglycemic drugs and treatment scheme were statistically analyzed.Results In 191 patients with hypertension complicating T2DM,the single drug use in the anti-hypertensive scheme accounted for 9.42 ％,two-drug combined use accounted for 64.91％,three-drug combined use for 17.8 ％ and four-drug combined use for 7.85 ％.The medication of ARB+CCB had the highest use frequency;the anti-hypertensive total effective rate was 96.86 ％.In the hypoglycemic schemes,the insulin use accounted for 30.37％,and the use frequency of metformin+ gliclazide was highest,the hypoglycemic total effective rate was 98.43％.Conclusion The medication for the patients suffering from hypertension complicating T2DM is relatively reasonable,and worth of being popularized and applied in clinical practice.

Objective: The paper inquires into a new external temporary cardiac pacing method. Method: The research uses a microcomputer-based multi-functional external temporary cardiac-pacing device made by the authors for sending pacing signals. The pacing mode and pacing rate of the device can be adjustable. The pacing pulse width and pacing current of the device can also be adjustable. It inserts a syringe necdle-like negative pacing pole into the chest muscle in the prior-cardiac area of a male adult mongrel dog; it pastes a positive pacing pole on the back area near heart of the dog. It takes intravenous injection isoptin 5mg into the male mongrel dog. After 5 minutes, the heartbeat of the dog suddenly stops; it does pacing experiment for the dog at this time and observes the results of the pacing experiment. Results: After temporary cardiac pacing, the heartbeat of the dog returns, pacing ECG of the dog appears, the pacing for the dog is active. Conclusions: It is a new and benefit external temporary cardiac pacing method.

Bacterial translocation is a major contributor to sepsis and multisystem organ failure.This paper reviews the studies in recent years.We will briefly introduce the advance in bacterial translocation,and expound its pathogenesis,prognosis,diagnosis,therapy,as well as significance and prospects.

Objective To study the diagnosis and treatment of duodenal papilla tumor (DPT). Methods Analyses were made on the clinical data of 22 patients with DPT proved by operation and pathology from 1977 to 1999. Results There were 17 patients with duodenal papillary carcinoma, 5 with duodenal papilloma in this series. Discomfort of the upper abdomen (16 cases) and jaundice (22 cases) were the main symptoms. Barium meal examination, BUS, CT and ERCP were very useful in the diagnosis of DPT. In this series, 19 of 22 patients received pancreaticoduodenctomy, and 3 received local reseciton, the resection rate was 100%. 15 patients (88.2%) were followed up, the 5 years survival rate was 73.3%, 7 years survival rate was 46.7%. Conclusions Duodenoscope and ERCP are credible methods for diagnosis of this disease, resection is the main way of treatment.

AIM: To investigate the mechanism of anti inflammatory action of theophylline on asthma. METHODS: Nineteen asthmatic patients were administered 200 mg sustained release theophylline twice daily for 4 weeks. The numbers or levels of CD4 +T lymphocytes, eosinophils, interleukin(IL) 5 and interferon gamma (IFN ?) in sputum pre and post administration were measured by direct immunofluorescene technique, Wright's stain and enzyme linked immunosorbent assay, respectively. The symptom scores and lung function were also evaluated. RESULTS: Theophylline treatment significantly improved symptom scores, FEV 1.0 and FEV 1.0 %(P 0.05 ). The mean (range) serum theophylline concentration in final steady state was 7.9 ( 3.9 - 14.7 ) mg?L -1 . CONCLUSION: The anti inflammatory action of theophylline in asthma may result from reduction of IL 5 production in the airways.

Objective To discuss the treatment mode of mass NBC casualties by field medical unit in NBC environment.Method Field medical unit rehearsed in a simulated NBC environment.Result The procedure for the rehearsal and treatment of field medical unit in NBC environment was determined.The importance of high-tech medical equipment for the obstructed patient flow was made clear.Conclusion High-tech medical equipment should be emphasized on to enhance the treatment capability of field medical unit.

Objective To understand antimicrobial resistance and therapeutic efficacy of imipenem/cilastatin and meropenem for treatment of multidrug-resistant Pseudomonas aeruginosa (MDRPA)from patients with mechanical ventilation.Methods From January 2010 to December 2015,78 patients with mechanical ventilation and isolated MDRPA from sputum cultures were selected and divided into imipenem/cilastatin (n=44)and meropenem(n=34) treatment groups,basic condition,time of emergence of drug resistance,and therapeutic efficacy of antimicrobial agents between two groups were compared.Results The basic data of two groups were comparable,before treat-ment by imipenem/cilastatin and meropenem,resistance rates of Pseudomonas aeruginosa (P .aeruginosa )to quinolones,ceftazidime,piperacillin,and amikacin were not significantly different (all P >0.05).After patients received antimicrobial agents for 6 days,difference in antimicrobial resistance between imipenem /cilastatin and meropenem treatment groups were not significantly different (22.73% vs 8.82%,P >0.05).On the 8th,10th,and 12th day of treatment,resistance rates of imipenem treatment group were 40.91%,77.27%,and 97.73%, respectively,which were all higher than meropenem treatment group (17.65%,32.35%,44.12%,respectively,all P <0.05).After the treatment with different antimicrobial agents,the average time for the emergence of resistance in imipenem/cilastatin and meropenem treatment group were 9.0 days and 13.5 days respectively.Therapeutic efficacy between two groups was not significantly different (64.71% vs 74.19%,P =0.41).Conclusion Compared with meropenem,imipenem/cilastatin shows higher risk for the emergence of drug resistance during therapy of P . aeruginosa infection in patients with mechanical ventilation,there is no significant difference in therapeutic efficacy between two groups of patients after 7 days of treatment.
