The Traditional Chinese Medicine is one system of medical theory and practice which combine literae humaniores with natural science.The TCM is the sapiential result of Chinese people against disease during long history which bases on traditional Chinese culture.In order to understand the advantages and features of TCM,it is necessary for us to start from the point of Chinese science and culture.The more national it is,the more international it is.We should avoid overlooking succession to tradition of TCM while pursue modernization of TCM.The cases have shown that the ancient TCM could brilliant in clinic application,makes the past serve the present and makes foreign things serve China are the most important method in modernization of TCM.TCM has scientism,the main way of the modernization of TCM is literae humaniores,which is not equal to TCM scientific. We should not only stress modernization of TCM reasonably,but also include in the modernization of literae humaniores.We should adopt advantages and face challenges,and form a new situation of multiplicate study and develope of TCM.

Objective To investigate of human esophageal squamous carcinoma cells(Eca-109) in which cyclooxygenase (COX)-2 gene was knocked down by adenovirus delivered siRNA.Methods Based on the plasmid pSUPER cloned with RNA polymerase Ⅲ-dependent promoter HI,the interfering plasmid psiRNA/COX-2 targeting human COX-2 mRNA was constructed,The siRNA/COX-2 fragment was derived from psiRNA/COX-2 digested by Not I and Xho 1.and was cloned into the shuttle plasmid pAdTrack.Then pAdTrack/siRNA/COX-2 was obtained and co transfected into the E.coli strain BJ5183 with the bone plasmid pAdEasy-1,the recombinant adenovirus Ad/siRNA/COX-2 was generated by homologous recombination.Having been packaged and amplified in cells 293,Ad/siRNA/COX-2 was transfected into Eca-109 cells.The PGE2 concentration in the cells culture supernatant was determined by ELISA,and the level of COX-2 mRNA in the cells was tested by real time PCR.Moreover,cell cycle and apoptosis were determined by flow cytometry,and cells growth curve was protracted.Results The recombinant adenovirus Ad/siRNA/COX-2 was successfully constructed.Ninty six hours after Ad/ siRNA/COX 2 transfecting into Eca 109 cells,COX-2 mRNA was reduced by 71.7%,and PGE2 concentration in the cells culture supernatant was decreased by 62.0%.Correspondingly,the growth of cells slowed down.At the same time,the cells in G0-G1 phase was increased by 32.24%,and those in S phase and G2-M phase were reduced by 16.38% and 15.86%.respectively.And cells apoptosis index was increased by 9.19%.Conclusion The adenovirus based-RNAi was capable of knocking down remarkably COX-2 of human esopbageal carcinoma cells,which lead to growth of cells slowing down.

Objective To explore the influencing factors and timing of acute cholecystitis laparoscopic surgery.Methods One hundred and sixty acute cholecystitis patients treated with laparoscopic surgery were divided into group A (56 cases,performed treatment within 24 h),group B (42 cases,performed treatment at 24 -48 h),group C ( 40 cases,performed treatment at 49 -72 h),group D (22 cases,performed treatment after 72 h).The operation time,rate of conversion to laparotomy,length of stay and average costs were compared among four groups and analyzed the impact of laparoscopic surgery conversion to laparotomy.Results The rate of conversion to laparotomy of group D [ 59.09％(13/22) ] was significantly higher than that in group A [ 19.64％(11/56) ] (P ＜ 0.01 ).The operation time of group A was the shortest and group D was the longest.The length of stay of group D was significantly longer than other groups (P ＜ 0.05 ).The costs of the four groups had no significant difference(P ＞ 0.05 ).Single factor analysis showed that white blood cell (WBC) count,body temperature,timing of surgery,gallbladder neck calculi incarceration were correlated with conversion to laparotomy(P ＜ 0.05 ).Multifactor analysis showed that WBC count,timing of surgery were independent risk factors of conversion to laparotomy (P ＜ 0.05 ).Conclusions WBC count,body temperature,timing of surgery,gallbladder neck calculi incarceration are correlated with acute cholecystitis laparoscopic surgery conversion to laparotomy.While WBC count and timing of surgery are independent risk factors.The best time of laparoscopic surgery is within 72 h and WBC count ＜ 15 x 109/L.

BACKGROUND: In recent years, nanoparticles has been rapidly developing in tumor hyperthermia, genophore research, and targeted drug therapy, particularly nanoparticle containing drug delivery systems will become another breach in tumor therapy.OBJECTIVE: To summarize the application and mechanism of superparamagnetic nanoparticles for cancer treatment in the medical field.METHODS: A computer-based online search was conducted in Medline for English language publications containing the key words of "superparamagnetic, nanoparticles, targeting" from January 2000 to October 2009. Relevant articles were also searched from CNKI with the same key words in Chinese from January 2005 to October 2009.RESULTS AND CONCLUSION: A total of 123 articles about targeting role of magnetic nanoparticles were included, and there were 24 in Chinese and 108 in English. Articles published earlier, duplicated, and similarly were excluded, and 30 references were finally included. Superparamagnetic nanoparticles characterized by targeting role under external magnetic field, and crystal of ferroso-ferric oxide did not has toxicity to cells. As a gene carrier and drug carrier, superparamagnetic nanoparticles were widely used in medical research and they also provided novel evidences for cancer treatment. By an external magnetic field, how to avoid a comprehensive system of phagocytic endothelial phagocytosis and prevent the course of treatment such as drug-induced thrombus is still inadequate.

Objective To evaluate the value of combined use of laparoscopy and hysteroscopy in the diagnosis of infertility. Methods Clinical data of 168 cases of infertility receiving examinations with laparoscopy and hysteroscopy from June 1999 to October 2003 were retrospectively reviewed.Results Hysteroscopic examinations found intrauterine diseases in 79 cases(79/168,47.0%),including 46 cases of endometrial hyperplasia or polyps(46/79,58.2%).Laparoscopic examinations showed organic pelvic diseases in 99 cases,including 85 cases of chronic pelvic inflammation,endometriosis or polycystic ovarian syndrome(85/99,85.9%).Both laparoscopy and hysteroscopy gave normal findings in 15 cases and abnormal findings in 39 cases.Unilateral or bilateral tubal obstruction was found in 90 cases by tubal patency tests under hysteroscope(90/168,53.6%) and in 78 cases by laparoscopy(78/168,46.4%). Conclusions Combined use of laparoscopy and hysteroscopy offers accurate diagnostic evidences in examinations of infertility.

DSS group,although without statistical significance.JOA score of two groups before and after surgery without statistical significance.[Conclusion]Developmental spinal stenosis is pathology found,which influences course of ossification of cervical posterior longitudinal ligament.The principal factor is trauma,which induces ossification of cervical posterior longitudinal ligament.Decompressed from a posterior approach is a reasonable treatment way.

Objective To investigate the effects of filter reuse on solute clearances, safety and oxidative stress parameters in on-line hemodiafiltration(HDF) . Methods 8 stable maintained uremic patients were treated by post-dilution on-line HDF with first-use or reuse F60 polysulfone filter, respectively. Both blood-side and dialysate-side solute clearances at 20 minute of HDF or during the whole session were measured. Whole blood interleukin-1?(IL-1?) production was monitored before HDF, after HDF, and at 20 minutes of HDF at both venous and arterial lines. Plasma before and after treatment and dialysate were collected for measuring total ascorbic acid, dehydroascorbic acid and total vitamin E. Restults No difference of small molecular substance clearances was observed in blood and dialysate side, while filter reuse group had a significantly higher dialysate side clearance and a significantly lower absorption clearance for ?2-microglobulin. In contrast with stable vitamin E concentration during dialysis, total ascorbic acid level decreased after treatment, with reuse group further inducing a reduced ration of dehydroascorbic acid to total ascorbic acid. No significant changes were found in whole blood IL-1? production within and between each group, so did intra-dialysis symptoms and temperature curves. Reuse filter also caused more albumin loss through high-flux membrane than that of first-use filter. Conclusions Although reuse filter can maintain both small and large molecular weight substance clearance, it increases albumin loss through high-flux membrane. Reuse filter does not stimulate white blood cell to produce more cytokine than the first-use filter, but it increases oxidative stress, and may harm uremic patients in a long run.

Acetaminophen(AAP)-induced hepatic injury is one of the common causes of drug-induced hepatic injury.Up to date,the mechanisms of AAP-induced hepatic injury are still incompletely understood.Recent advances suggest that reactive metabolite formation,glutathione depletion,alkylation of proteins,especially mitochondrial proteins and peroxynitrite formation are critical initiating events for the toxicity.This review will focus on more recent advances in mitochondrial dysfunction after AAP overdose.Additional,oxidative stress and inflammatory mediators are also important for the overall outcome.
