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.

Background and purpose. Chemotherapy is a standard treatment for patients with advanced stage non-small cell lung cancer (NSCLC) However, platinum based chemotherapeutic regimen haves high toxicity profile to normal tissues. Lobaplatin (LBP) is a new third-generation antitumour platinum drug. Studies abroad have shown that Iobaplatin has an anticancer activity similar to cisplatin with better tolerance and is more effective for those who are resistant to cisplatin. This study was aimed to observe the effectiveness and toxicities of lobaplatin combined with vinorelbine (NVB) for the treatment of advanced NSCLC. Methods: Sixty-four patients pathologically diagnosed as clinical stage Ⅲ_B-Ⅳ NSCLC who did not receive treatment before, were randomly assigned to two groups. NL group (NVB+LBP): LBP at a dose of 30 mg/m~2 intravenous infusion on day 1, and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. NP group (NVB+DDP): Cisplatin (DDP) at a dose of 30 mg/m~2 intravenous infusion on day 1, 2 and 3 and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. Treatments were repeated every 21-28 days for 3 cycles. Results: For 34 patients of NL group, there were CR (1 cases), PR(13 cases), NC(15 cases), and PD(5 cases). The overall response rate (RR) was 41.2%, disease control rate (DCR) was 85.3%. In NP group: RR was 43.3%, DCR was 83.3% (X~2=0.05, P>0.05). Median overall survival time was 8.6 months and 8.9 months for NL group and NP group, respectively. The main toxicities in NL group were myelosuppression. Digestive toxicity such as anorexia, nausea,vomiting were less than those in the NP group (X~2=7.43, P<0.05), Peripheral hour,toxicity, serious liver and renal toxicity were not observed in NL group. Conclusion: Compared with cisplatin plus vinorelbine, domestic lobaplatin with vinorelbine yielded similar efficacies for NSCLC, but had less toxicity and well tolerate.

Objective To evaluate the overall effectiveness of microsurgery for elderly pituitary adenomas,and to select the optimal surgical approaches for this type of tumor. Methods Microsurgical operation was performed on 190 patients with elderly pituitary ademomas,and these patients were retrospectively analysed. The 190 cases were divided into transsphenoidal group and transcranial group with a comparison analysis of respective removal percentage,postoperative complication and follow-up. Results In the transsphenoidal group with 158 cases,total removal were performed in 112 cases (71.0%),subtotal removal in 30 cases,partial removal in 16 cases. In the transcranial group with 32 cases,total removal were performed in 8 cases (25.0%),subtotal removal in 16 cases,partial removal in 8 cases. Conclusions Transsphenoidal approach was characterized by shorter hospitalization period,less therapeutic charges and better postoperative quality of life and it should be of choice for the treatment of the elderly pituitary adenomas.

Objective To study the apoptosis of gallbladder carcinoma cell line GBC-SD induced by antisense oligodeoxynucleotide (ASODN) targeting survivin. Methods ASODN targeting survivin was transfected into GBC-SD cells mediated by lipofectin. Cultured cells were divided into 3 groups: control group,sense oligonucleotide (SODN) group and ASODN group. After transfected for 16 h, the cultured cells were harvested and the following texts were carried out. The expression of survivin mRNA was detected by RT-PCR. Flow cytometer were used to detect apoptosis. Morphological changes were observed by electron microscopy. Results The expression of survivin mRNA was decreased 47.83% in ASODN group while apoptosis was increased from (0.50?0.23)% to (26.28? 3.91)%. Abnormal morphological changes of cells were observed in ASODN group and apoptosis bodies were found in some gallbladder carcinoma cells. Conclusion The expression of survivin may be decreased in GBC-SD cells after ASODN transfection.ASODN targeting survivin could induce gallbladder carcinoma cells apoptosis effectively.

Objective To investigate the correlation between EEG severity and secondary epilepsy in elderly patients with cerebral infarction.Methods 128 cases with cerebral infarction were selected as the research subjects. According to whether the patients happened secondary epilepsy,they were divided into the observation group (65 cases) and the control group (63 cases).The difference of EEG severity between the two groups was compared,and its correlation with secondary epilepsy was analyzed.Results There were 18 cases (27.69%)in the observation group graded as moderate differences,which was significantly higher than that in the control group of 12 cases (19.05%), the difference was statistically significant (χ2 =4.43,P =0.04).There were 23 cases (35.38%)in the observation group graded as severe differences,which was significantly higher than that in the control group of 9 cases (13.85%),the difference was statistically significant (χ2 =6.51,P =0.01 ).There were 21 cases(32.31%)of EEG changes of observation group being only diffuse abnormalities forms,which was significantly higher than that of the control group of 11 cases(17.46%),the difference was statistically significant (χ2 =4.18,P =0.04).There were 28 cases(43.08%)of EEG changes of the observation group being both focal abnormalities and diffuse abnor-malities forms,which was significantly higher than that of the control group of 14 cases(22.22%),the difference was statistically significant (χ2 =5.40,P =0.02).Compared open -closed test,hyperventilation provocation test results of the observation group being abnormal or not fit with the control group,the difference was not statistically significant (P >0.05).Conclusion According to the classification of EEG,EEG changes and EEG related tests to determine the severity of EEG.The more severe EEG,the greater the possibility of secondary epilepsy happen in patients with cerebral infarction.
