Traditional Chinese medicine is one of the component parts of the international health care system. It has been an inevitable trend to merge traditional Chinese medicine into systemic medicine. Along with the emergence of the concept of systemic disease, the wide dissemination of evidence-based medicine and the establishment of thought pattern of systemic medicine, the exploration emphasis of modern medical science has been transferred from microcosmic or solid structure to macrocosmic unit and system relation. The mainstream development of modern medical science is to integrate different medical systems into a complete system. Therefore, the integration of traditional Chinese medicine and Western medicine is also necessary under this condition.

?Corneal collagen cross-linking ( CXL ) could increase the mechanical strength, biological stability and halt ectasia progression due to covalent bond formed by photochemical reaction between ultraviolet - A and emulsion of riboflavin between collagen fibers in corneal stroma. Corneal melting is an autoimmune related noninfectious corneal ulcer. The mechanism of corneal melting, major treatment, the basic fundamental of ultraviolet- A riboflavin induced CXL and the clinical researches status and experiment in CXL were summarized in the study.

Objective To investigate the expression of netrin-1 in placenta from patients with pre- eclampsia and the relation to placental angiogenesis.Methods Twenty patients with pre-eclampsia(12 mild cases and 8 severe cases)and 20 normal late pregnant women were investigated.The expression of netrin-1 mRNA and protein was determined with RT-PCR and Western blotting respectively.The placenta vascular density was examined by immunohistochemical F8 staining.Results (1)The values of netrin-1 mRNA in normal group and pre-eclampsia groups were 0.51?0.08 and 0.41?0.06;The values of netrin- 1 protein in normal group and pre-eclampsia groups were 26.4?1.8 and 20.5?1.3(P

The genesis of primary hepatocellular carcinoma(PHC)is a complicated biology process involve in multiple factors.It has been paid more attention to the genetic susceptibility in the pathogenesis and development of PHC.As the third generation of molecular genetic marker,single nucleotide polymorphism(SNP)becomes a hot topic in the research field of PHC.This article summarized the research evolution of the relationship between the susceptible gene SNP of PHC and PHC susceptibility.

Objective To compare the effects of classic intrafascial supracervical hysterectomy(CISH)and laparoscope-assisted vaginal hysterectomy(LAVH)on structure and function of the pelvic floor in women.Methods From March 2003 to December 2005,totally 35 cases of CISH and 44 cases of LAVH were performed in our hospital.The patients were followed up for 22 to 38 months after the operations.During the period,they received physical examination and life quality questionnaire,by which the degree of pelvic organ prolapse and pelvic floor function were evaluated.Results The incidence of cystocele in CISH group was significantly lower than that in LAVH group [11.4%(4/35)vs 34.1%(15/44),?2=5.481,P=0.019],whereas,no significant difference was found in the incidence of rectocele between the two groups [17.1%(6/35)vs 13.6%(6/44),?2=0.186,P=0.666].Seven(15.9%)patients in the LAVH group developed cervix prolapse,while none of the CISH group had such a situation(P=0.016).Life quality questionnaire showed that 5 patients in CISH group and 16 patients in LAVH group were satisfied with their sexual life [14.3%(5/35)vs 38.1%(16/42),?2=5.456,P=0.019].Conclusion CISH is superior to LAVH in protecting the structure and function of the pelvic floor.

Objective To discuss the advantages and disadvantages of the mammography and ultrasound examination for breast cancer diagnosis.Methods Totally 84 breast cancer patients enrolled in our study.All of the patients underwent mammography before surgery,and 69 of them received both mammography and ultrasound examination.The data were studied retrospectively.Results 84 foci were found totally on mammography and were all diagnosed above ACR BIRAD grade 4 by X-ray.Two of the 13 cases smaller than 2 cm in diameter were diagnosed as grade 3 by ultrasound.Eleven cases with microcalcification were diagnosed as grade 2（1case）and 3（1case）by ultrasound.Only 1 of the 6 cases shown as distortion was diagnosed as 5 by ultrasound.Conclusion X-ray has the superiority to ultrasound for distortion and microcalcification.For the mass smaller than 2 cm in diameter,both of X-ray and ultrasound may underestimate.

To study the drug-drug interaction of morinidazole and warfarin and its application, a sensitive and rapid liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the determination of R-warfarin/S-warfarin in human plasma. In a random, two-period crossover study, 12 healthy volunteers received a single oral dose of 5 mg racemic warfarin in the absence and presence of morinidazole. Blood samples were collected according to a pre-designed time schedule. R-warfarin, S-warfarin and methyclothiazide were extracted with ethylether : methylenechloride (3 : 2), then separated on a Astec Chirobiotic V (150 mm x 4.6 mm ID, 5 microm) column using 5 mmol x L(-1) ammonium acetate (pH 4.0) - acetonitrile as mobile phase at a flow-rate of 1.5 mL x min(-1). The mobile phase was splitted and 0.5 mL x min(-1) was introduced into MS. A tandem mass spectrometer equipped with electrospray ionization source was used as detector and operated in the negative ion mode. Quantification was performed using multiple reaction monitoring (MRM). The resolution of warfarin enantiomers is 1.56. The linear calibration curves for R-warfarin and S-warfarin both were obtained in the concentration range of 5 - 1 000 ng x mL(-1). Intra- and inter-day relative standard deviation (RSD) for R-warfarin and S-warfarin over the entire concentration range across three validation runs was both less than 10%, and relative error (RE) ranged from -4.9% to 0.7%, separately. The method herein described is effective and convenient, and suitable for the study of metabolic interaction between morinidazole and warfarin. The results showed that coadministration of warfarin with morinidazole did not affect the pharmacokinetics of either R-warfarin or S-warfarin.

As one branch of epigenetics, the sirtuins family ( ClassⅢ histone deacetylase) receive much attention in recent years. SIRT1 as the most famous of the sirtuins family members has been verified involved in a variety of age-related diseases. While the SIRT1 formation is paid more and more attention in age-related cataract. Now, we briefly overviewed the research progress on the role of SIRT1 in age-related cataract.
