Objective To explore the clinical application of laparoscopic splenectomy in treatment of spleen disease at our hospital.Methods We reviewed laparoscopic splenectomy carried out at our hospital since 1995,patients were grouped by date.63 laparoscopic splenectomies were divided into six groups.Operation time,intraoperative blood loss,postoperative hospital stay,time to feeding,days of drainage,amount of drainage,postoperative complications and indications for surgery were compared.Results Patient's age averaged at 44.19 years,body mass index averaged at 23.75,3 patients were converted to open surgery.Mean operating time,blood loss,postoperative hospital stay,time to feeding,converting rate in the 53 cases which had the surgery after 2003 were much better than the 10 cases before 2003.Surgical indications for laparoscopic splenectomy were limited to hematopoietic disease related splemegaly before 2003,the indication range significantly expanded after 2003,during which laparoscopic splenectomy were mainly applied to treat spleen tumors.Conclusions There is a marked learning curve in laparoscopic splenectomy after 10 surgeries before 2003 we have achieved the level.With the suitable approach,apparatus and skillful technique,laparoscopic splenectomy is safe and feasible to treat tumors of the spleen.

Objective To explore the clinical characteristics and diagnosis of Epstein-Barr(EB) virus encephalitis(EBE) in children. Methods The verification of EBE was based on detection of EBV DNA in cerebrospinal fluid (CSF) by fluorogenic quantitative PCR(FQ-PCR) and Nest-PCR. The clinical and CSF changes of 27 EBE cases and 26 controls were analyzed and compared. Results EB-DNA in CSF by FQ-PCR of 13 cases of EBE was (2.82?2.03)?10 3copies.There was no significant difference in clinical manifestations between EBE and HSE groups, except that WBC in CSF of EBE was lower than those of HSE.Conclusions EBE is not infrequent, about 10 % of encephalitis in children. EBE is always present independently, which is not a complication of infectious mononucleosis(IM).Detection of EBV-DNA in CSF is a sensitive and specific test for diagnosing of EBE. Early treatment may be beneficial to the prognosis of EBE.

Objective By detecting the mutations spectrum of phenylalanine hydroxylase(PAH)gene in phe-nylketonuria(PKU)patients and their parents. The researchers analyzed the gene mutation features and high - frequency mutations and determined the relationship between the genotype and the phenotype,which would provide a theoretical basis for the early diagnosis and genetic consultation of PKU children in the region. Methods In this study,13 exons and their flanking introns of the PAH gene in 32 PKU patients and their parents from Wuxi and Suqian in Jiangsu province were sequenced by using the next - generation sequencing(NGS)technology. Results Sixty - one mutant sites and 32 mutant genes were detected in 32 PKU patients,and the mutation detection rate was 95. 31%(61 / 64 cases). The variants at c. 721C ﹥ T,c. 1068C ﹥ A,c. 611A ﹥ G,c. 1197A ﹥ T,c. 728G ﹥ A,c. 331C ﹥ T and c. 442 -1G ﹥ A were common mutations in the region with mutation frequency over 5% . What's more,4 novel variants of c. 699C ﹥ G,c. 265C ﹥ T,c. 722G ﹥ A and c. 1194A ﹥ G were found. Of those,c. 699C ﹥ G was not recorded in the PAH variant database and HGMD database and. c. 265C ﹥ T,c. 722G ﹥ A,and c. 1194A ﹥ G were first reported in the Chi-nese population. Genotype - accurate biochemical phenotype correlation by using the Guldberg AV system revealed con-sistency rate of 38. 0%(8 / 21 cases),which the consistency rate between accurate biochemical phenotype and predic-tive phenotype of moderate to severe genotype was 92. 3%(12 / 13 cases),and mild genotype was 50. 0%(4 / 8 cases). Conclusions The PAH gene variants of PKU patients in Jiangsu province are distributed mainly in exons 7,of which the highest frequency gene mutation is c. 721 c ﹥ T. Moreover,one novel variant c. 699C ﹥ G was reported for the first time. The PKU children inherit the PAH mutation gene mainly from both parents. There are definite correlation between the genotypes and phenotypes.

Objective To understand the prevalence of smoking in different sub-populations in Xuzhou area so as to develop effective tobacco control policies. Methods Through multi-stage randomized cluster sampling,a face-to-face study with standard questionnaire was carried out among residents aged above 15 years,from June to December 2008,with descriptive nature. Results Totally,44 686 people,with 21 524 males and 23 162 females at age 15 and over were investigated,including 34 391 of them from rural areas and 10 295 from the urban population. Data regarding rates on ever smoked and current smoking,regular smoking,heavy smoking,and average numbers of cigarettes smoked per day,types of tobacco products smoked,rates on quitting smoking successfully,relapse,passive smoke exposure etc.,were 22.45%,21.40%,15.49%,9.49%,15.09/d,4.68%,5.91% and 14.12% respectively. There were no significant differences in the rates of overall smoking,current smoking and regular smoking among urban and rural residents (P>0.05). However,rates of successfully quitting smoking and passive smoke exposure in the urban areas were higher than those in the rural areas (P<0.05). Rates regarding relapse,heavy smoking and average numbers of cigarettes smoked per day in the rural areas were higher than those in the urban areas(P<0.05). Rates on smoking,current smoking,regular smoking,heavy smoking,relapse and average numbers of cigarettes smoked per day were higher in males than those in females (P<0.05). Rates of quitting smoking successfully and passive smoke exposure were higher in females than those in males (P< 0.05). The major types of tobacco products smoked by people aged 15 years old and above were cigarettes (85.17%),and Chinese pipes (3.24%). Conclusion Smoking was quite common in people from Xuzhou. Our data suggested that health education should be strengthened and sustainable intervention measures be developed and implemented to control the tobacco use in the area.

The study on the effective core formulae (CEF) not only summarized traditional chinese medicine (TCM) treatment experience, but also helped reveal the underlying knowledge in the formulation of TCM prescriptions. The aim of the present paper was to investigate the method of data mining for the discovery of core effective formulae for lung cancer. In the present study, a prescription fingerprint approach was used to characterize the staged prescription information of patients. The D index was used to screen potential beneficial herbs. Then, based on a herbal compatibility network, the maximal clique searching algorithm (BK algorithm) and survival analysis were applied to discover CEF for lung cancer, and a mining analysis was made for the 322 cases from Longhua hospital. The correlation between prescriptions and survival time was analyzed by prescription fingerprints. Forty-three potentially beneficial herbs were obtained, and two CEFs were significant for the survival time by a parametric survival model based on lognormal distribution, the results were verified by a multivariate survival model. The rules of combination of the two CEFs basically conform to TCM onco-therapeutic theory of strengthening the body resistance and the actual conditions in clinic. All results showed that the established approach was feasible for discovering the core effective formulae for lung cancer and mining survival data for complex TCM onco-therapy.

OBJECTIVE:To provide reference for strengthening the safety of the combination use of CYP3A4 inhibitors with statins in clinical treatment. METHODS:30 cases per month(totally 300 cases)(the hospitalization time was more than 10 days) discharged from the cardiology department of a third-level class A hospital during Jan. to Oct. 2013 were selected randomly,and statistical analysis was made into general information of patients,whether to use statins and CYP3A4 inhibitor,and whether to monitor safety indicators of liver and kidney function and creatine kinase. RESULTS:Totally 291 patients were treated with statins with a total use rate of 97%,including 265 cases of atorvastatin and 11 cases of simvastatin. The CYP3A4 inhibitors were com-bined with amlodipine,diltiazem,verapammy,amiodarone,Ginkgo biloba leaf,fenofibrate and clarithromycin,etc.,and 162 (59%) patients were given the combination use of simvastatin or atorvastatin with CYP3A4 inhibitors. But the liver and kidney function,creatine kinase and other safety indicators were not monitored by laboratory examination during medication. CONCLU-SIONS:Atorvastatin and simvastatin are used commonly in patients with cardiovascular disease,and the combination use rate with CYP3A4 inhibitor is relatively higher and needs long-term medication,drug dosage should be limited according to the direction of instructions and the adverse reactions induced by drug interactions should be noticed to strengthen medication monitor and education for patients.

Objective To study the efficacy of L-3,5-diiodotyrosine (DIT) and inorganic iodine (KIO3) in iodine-deficiency Wistar rats.Methods Sixty Wistar rats,weighting about 160-180 g,were divided into two groups according to body weight by the random number table method:iodine-deficiency model (40 rats) was fed with low-iodine food (the iodine content was 35.9 μg/kg);optimal-iodine model (20 rats) was fed with low-iodine food and given with KIO3 water (the iodine content was 18 mg/L) 0.5 ml by intragastric once a day.Model was established for 3 months.Iodine-deficiency model was subdivided into low iodine (LI) group,KIO3 group and DIT group,eight,nine,ten rats in each group;from optimal-iodine model,nine rats were randomly selected as optimal iodine (NI) group.LI group was fed with low-iodine food;KIO3 group was fed with low-iodine food and given with KIO3 water (the iodine content was 18 mg/L) 0.5 ml by intragastric once a day;DIT group was fed with low-iodine food and given with DIT water (the iodine content was 18 mg/L) 0.5 ml by intragastric once a day;NI group was fed with low-iodine food and given with KIO3 water (the iodine content was 18 mg/L) 0.5 ml by intragastric once a day.After 3 months,24-hour urine of the rats was collected.According to the method for determination of iodine in urine by As3 +-Ce4+ catalytic spectrophotometry (WS/T 107-2006),iodine content in urine was detected.Rats were anesthetized intraperitoneally with 25％ urethane,blood from abdominal aortic was collected to determinate the serum thyroid hormone [total triiodothyronine (TT3),total thyroxine (TT4),free triiodothyronine (FT3),free thyroxine (FT4)] level in rats by automatic electrochemical luminescence immunoassay.All the rats were sacrificed to analyze the thyroid weight.Results ① The urine iodine showed significant differences in the four groups (x2 =25.24,P ＜ 0.05).The median of urine iodine concentration in the LI,NI,KIO3 and DIT groups were 3.00,286.14,223.37,214.33 μg/L,respectively.The urine iodine concentration in LI group was significantly lower than those of other three groups (all P ＜ 0.05).② The serum TT3,TT4,FT3,FT4 levels showed significant differences in the four groups (F =63.48,140.73,130.20,365.27,all P ＜ 0.05).And the hormone levels in KIO3 group were lower than those of the DIT group [TT3:(1.57 ± 0.20) vs.(1.97 ± 0.18) mmol/L,TT4:(51.23 ± 4.90) vs.(71.94 ± 5.27) mmol/L,FT3:(5.34 ± 0.45) vs.(6.98 ± 0.33) pmol/L,FT4:(26.18 ± 2.30) vs.(35.47 ± 2.28) pmol/L,all P ＜ 0.05].③The color of thyroid in KIO3 and DIT groups became pale pink.The absolute and relative thyroid weight showed significant differences in the four groups (F =225.05,345.40,all P ＜ 0.05).The absolute thyroid weight [(31.76 ± 1.75) mg] and relative thyroid weight [(11.69 ± 3.47) mg/100 g] in DIT group was lower than that of the KIO3 group [(36.31 ± 5.23) mg,(12.83 ± 4.38) mg/100 g,all P ＜ 0.05].Conclusion Animal experimental results show that DIT has a better iodine-supplementing efficacy than that of KIO3.
