Objective To evaluate the efficacy and priority of laparoscopy in the diagnosis and treatment of acute peritonitis. Methods Clinical data of 133 cases of acute peritonitis diagnosed and treated under laparoscope between April 2001 and October 2004 were retrospectively reviewed. Results Of the 133 cases, there were 60 cases of gastroduodenal perforation, 15 cases of acute cholecystitis, 8 cases of gallbladder perforation, 2 cases of sigmoid colon perforation, 35 cases of acute perforated appendicitis, 3 cases of jejunal diverticulum perforation, 1 case of foramen of Winslow hernia, 4 cases of acute pancreatitis, and 5 cases of primary peritonitis. The diagnostic accuracy was 100%. All the patients were treated laparoscopically without complications. Conclusions Laparoscopy gives a high diagnostic accuracy for acute peritonitis. The rationale for the use of it lies in the possibility of avoiding time- consuming preoperative B-ultrasonography or CT scans and performing minimally invasive surgical interventions directly.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.

Objective To compare the immediate effects of extracorporeal shock wave therapy with that of joint mobilization plus short wave therapy in treating scapulohumeral periarthritis, and to elucidate the mechanism of extracorporeal shock wave therapy and how it should be used. Methods Forty-seven patients diagnosed with scapulohumeral periarthritis were selected and randomized into two groups, a treatment group (n = 26) treated with extracorporeal shock wave therapy, and a control group ( n = 21 ) treated with joint mobilization plus short wave therapy. The short form of the McGill pain questionnaire (SF-MPQ) and range of motion (ROM) measurements were used to evaluate shoulder function. Results Compared with baseline, both groups improved significantly af-ter treatment, but the immediate effect in the treatment group was superior to that in the control group. Concln-sions As a safe, time-saving and effective therapy, extracorpnreal shock waves could be used to treat scapulo-humeral periarthritis.

Objective To determine the effect of combination of chest physiotherapy (CPT) and intermittent non-invasive ventilation for chronic obstructive pulmonary disease (COPD) patients with respiratory failure. Methods Ninety COPD patients with intermittent bi-level positive airway pressure (BiPAP) ventilation were randomly divided into 2 groups : control group (n=45) received BiPAP treatment after conventional anti-infection, phlegm treatment and support treatment; CPT group (n=45) received CPT before BiPAP treatment. Clinical symptoms, chest signs, chest X-ray, time of BiPAP therapy, PaO2, and PaCO2 after the treatment were evaluated. Results Compared with with the control group, patients in the CPT group significantly improved in clinical symptoms, chest signs, chest X-ray absorption as well as shorter BiPAP therapy time, PaO2 increase and PaCO2 decrease(P<0.05). Conclusion For COPD patients who need intermittent non-invasive BiPAP ventilation, receiving CPT can effectively improve the therapeutic effect. CPT and intermittent non in-vasive BiPAP ventilation cooperate in the treatment of COPD patients with respirstory failure.

Objective Brain metastasis(BM) is unusual in colorectal carcinoma(CRC) patients.This study was to evaluate the characteristics and prognosis of brain metastasis of colorectal carcinoma patients.Methods Twenty-eight consecutive CRC patients underwent surgical resection for BM between January 2001 and December 2008.The clinical data were analyzed by univariate (logrank) and Cox regression test.Results The median age at BM diagnosis from CRC was 57 years(41-75 years).Median survival after neurosurgical intervention was 9.4 months.The 1-year and 5-year survival rates were 28.9%and 7.1%,respectively.Seventeen patients(61%)had concurrent systemic metastasis.All patients were symptomatic with neurologic deficits and symptoms.On multivariate analysis,gender,infratentorial location of lesions and characteristics of primary CRC had no significant impact on survival.Two factors were signitlcandy associated with better survival:single brain metastases and absence of extracranial metastases.Perioperative mortality was zero.There were no difference of survival among patients undergoing resection alone and resection combined with whole brain radiotherapy (WBRT) or stereotactic radiosurgery(SRS). Conclusions Brain metastases from colorectal cancer is an evil omen of poor prognosis of CRC patients.Sursical resection of symptomatic brain metastases from colorectal cancer is relatively safe and provides the opportunity for prolonged survival.
