Objective To investigate the prevalent characteristics of children with viral pneumonia in different areas and years.Methods The viral antigen of cells of nasopharyngeal secretions was detected by the method of alkaline phosphatasea anti-alkalinephhosphatase in viral pneumonia children in different areas and years.Results Among 627cases , there were 290 positive cases and 14 cases were infected by 2 viral strains. Three hundred and four positive viral strains,71 cases (23.35%) were RS virus infection, 47 cases (15.46%) were AD virus infection, 74 cases (24.34%) were FLU-A virus infection,50 cases (16.44%) were FLU-B virus infection, 47 cases (15.46%) were PIV1,3 virus infection, and 15 cases (4.93%) were PIV2 virus infection. But in different areas, the kind of the viral strain of the highest infection rate was different. The viral detection rate in autumn and winter was the highest and in summer was the lowest. Conclusions FLU-A virus is the main etiological agent of children viral pneumonia,but the main etiological agent in different areas is different. In autumn and winter, the viral infection rate is high. The chance of viral infection of lower respiratory tract of big children is reduced.

Objective To discuss the applied value of multislice spiral CT(MSCT) in diagnosing and localizing the embedded supernumerary teeth. Methods A total of 43 cases with the embedded supernumerary teeth were undergone MSCT using shaded surface display(SSD), minimum intensity projection(MIP) and multiplanar reformation(MPR) to present the form and location of the embedded supernumerary teeth and to determine the surgical style.The result of image was retrospectively analysed after operation.Results The reconstruction images,could clearly show the dental surface image including crown, root, neck and root bifurcation, labial or palatal location, eruption orientation and relation with dentition in anterior maxilla. The position of 52 embedded supernumerary teeth in 43 patients were completely confirmed by surgery with accuracy of 100%. All patients were well healed with no infection and injury to nearby teeth. Conclusion The Embedded supernumerary teeth in bone can be detected by MSCT and MSCT can be used as an important examination technique before surgical and orthodontic treatment.

Objective To investigate the efficacy of patient-controlled epidural analgesia(PCEA)with ropivacaine plus fentanyl for postoperative analgesia after suprapubic prostatectomy(SPP).Methods Thirty-six ASAⅡorⅢpatients aged 62-78 yrs weighing 52-84 kg undergoing SPP were randomly divided into 3 groups with 12 patients in each group:groupⅠreceived PCEA with 0.12% ropivacaine and fentanyl 1?g?ml~(-1);groupⅡreceived PCEA with 2% ropivacaine and fentanyl 1?g?ml~(-1) and groupⅢreceived patient-controlled intravenous analgesia(PCIA)with morphine 0.2 mg?ml~(-1).Postoperative pain was assessed using VAS(0=no pain,10= worst pain).The degree of motor blockade(modified Bromage scale)was evaluated at 6,24,48 and 72 h after operation(T_(1-4)).Bladder spasm episodes were recorded.Side effects including nausea,vomiting and pruritus and the total number of RBC in rinse solution were also recorded.Results(1)Bromage score(0=no motor block,3 =inability to flex ankle joint)was significantly higher in groupⅠandⅡthan in groupⅢat T1(6 h after op.), but significantly lower in groupⅠandⅢthan in groupⅡat T_(2-4)(24-72 h after operation).(2)VAS score(0= no pain,10=worst pain)was not significantly different among the 3 groups without bladder spasm but significantly higher in groupⅢthan in other 2 groups during episodes of bladder spasm.(3)The number of bladder spasm episodes was not significantly different among the 3 groups within 6h after operation,but was significant larger in groupⅢthan in the other two groups during 6-72 h after operation.During 6-24 h after operation more bladder spasm attacks occurred in groupⅠthan in groupⅡ.(4)The incidence of side effects was significantly lower and the total number of RBC in rinse solution was significantly smaller in groupⅠandⅡthan in groupⅢConclusion PCEA with 0.12% or 2% ropivacaine plus fentanyl can effectively reduce the number of bladder spasm attack and postoperative bladder bleeding.Different concentrations of ropivacaine should be used for PCEA during different postoperative periods.

OBJECTIVE: To establish a method of fingerprint position, sample transfer and fingerprint DNA extraction in contact samples. METHODS: Sixty-six cases were visualized by 502 glue fingerprint fumigation. Two methods, ordinary wipe and acetone wipe, were used to transfer cast-off cells of fingerprints from testing samples, respectively. DNA was extracted and purified by ultramicro magnetic bead kit. The data was resolved on genetic analysis after amplification. RESULTS: In 33 samples, 30 samples got better STR analysis by acetone wipe method. The peak range was 1,000-4,000 RFU and peak shapes were equable. It was hard to get ideal STR typing by ordinary wipe method. CONCLUSION The samples are visualized by 502 glue fingerprint fumigation and the case-off cells are transferred by acetone wipe method. The method shows better STR analysis result, which might be a better method for forensic science practice.

Objective To summarize the experience of clinical diagnosis and treatment for recurrence and progress of relieved myastbenia gravis after thymectomy. Methods 22 recurrent and progressive after relieved pa-tients with myasthenia gravis who underwent thymectomy were retrospectively analyzed. The remission therapy was conducted with combined glucocorticoid and anticholinesterase and its effectiveness was estimated. Results It was 1,17,4 as better Osserman scale Ⅰ , Ⅱ , Ⅲ respectively before operation but 15,6,1 as better Osserman scale Ⅱ , Ⅲ, Ⅳ respectively in recurrence and progress of relieved myasthenia gravis after thymectomy besides 6 with myas-thenic crisis. Complete remission and partial remission were gained in 9 patients and 12 patients respectively. There was 1 hospital-death. Conclusions Recurrence and progress can occur in any patient of relieved myasthenia gravis after thymectomy. Bulbar myasthenia gravis is usually presented as dysphagia. Reasonable administration of glucocor-tieoid could improve majority of recurrence and progress of relieved myasthenia gravis after thymectomy but responses poorly to the anticholinesterases.
