At present, a number of scientific research achievements has been formed. Scientific achievement is the crystallization of great efforts from scientific workers, and it's also the valuable treasure of human civilization. Standardization is an important way to promote the international communication of Chinese medicine, and it's significant in boosting China's scientific and technological progress, improving market competitiveness and promoting international trade. Transformation of scientific research to the guideline is not only beneficial to improving the technology content of the standard, but also to the conversion from scientific research achievements into productivity. Therefore, only by absorbing the advanced scientific and technological achievements, reproducing the theory of traditional Chinese medicine (TCM) and medical technology in standard form, can make TCM keep pace with the times. This study preliminarily explores for the method to transform scientific research achievements into guideline, in order to provide reference for the future technical specifications, thus to further the development of TCM.

Objective To investigate the infection of chlamydiae trachomahs(CT) and myoplasmas in urogenital tract and antibiotic susceptibility of cultured genital myoplasmas.Methods 5095 patients with urogenital tract infection were detected with mycoplasma identification susceptibility testing reagent kit,and the drug susceptibility to eight antibiotics of ureaplasma urealyticum (Uu) and mycoplasm hominid (Mh) were tested by broth microdilution method.And chlamydiae trachomatis was examined by golden standard method.Results In 5095 cases, 417cases(8 2%) were infected with chlamydiae trachomatis, and the infective rate in woman(11 2%) was statistically higher than that in man(6 2%). 1728 cases(33 9%) were infected with mycoplasma, and the infective rate in woman(43 0%) was statistically higher than that in man(28 0%).The cases infected with simple UU(1251,24 6%) were more than that in the cases infected with simple Mh(71,1 4%) and the mixed infected cases(406,8 0%). Drug sensitivity to erythromycin, roxithromycin, josamycin, azithromycin, doxycycline, minocin,ofloxacin, ciprofloxacin in Uu infection were 60 3%,67 5%,73 2%,85 3%,55 7%,40 1%,25 6%,2 7%,respectively;while the mixed infection of Mh and Uu had resistance to the eight antibiotics on the different degree.Conclusions The infective rate of chlamydiae trachomatis and myoplasma in urogential tract and the resistance rates to 8 antibiotics in Hunan province were in a higher level, compared with other area inland. It is necessary to develop antibiotic susceptibility test,in addition to the myoplasma culture for guiding the clinical therapy.

OBJECTIVE:To study the improvement effect of Z-Guggulsterone(Z-GL)on blood coagulation and vascular endo-thelial functions of acute blood-stasis model rats and its mechanism. METHODS:40 rats were randomly divided into normal group,model group,positive group(Aspirin tablet,50 mg/kg)and Z-GL low-dose and high-dose groups(25,50 mg/kg),with 8 rats in each group. They were given relevant medicine intragastrically every 12 h,and normal group and model group were given constant volume of normal saline intragastrically for consecutive 7 times. After the fifth administration,except for normal group, those groups were given adrenalin hydrochloride subcutaneously+ice-cold water to induce acute blood-stasis model. Within 30 min after the last administration,aorta abdominalis sample were selected to detect the coagulation parameters [prothrombin time(PT), thrombin time (TT),activated partialthromboplastin time (APTT),fibrinogen (FIB)],and pathological changes of carotid artery were observed. Human umbilical vein endothelial cells (HUEVCs) were divided into blank group (normal saline),model group (normal saline) and Z-GL low-concentration and high-concentration groups (25,50 μmol/L). After culturing for 24 h,the cells were exposed to glucose and oxygen deprivation for 6 h in model group and Z-GL groups. The expression of p-eNOS protein was detected. Other cells were selected,grouped,administrated and treated as above cells,and the NO level of these cells were detect-ed. RESULTS:Compared with normal group,PT,TT and APTT were all shortened in model group,while FIB content was in-creased (P<0.01);vascular endothelium was injured,and endothelial cells fell off from the wall. Compared with model group, PT,TT and APTT were prolonged in administration groups,while FIB content was decreased(P<0.05 or P<0.01);vascular en-dothelium injury was relieved. Results of p-eNOS protein and NO levels determination showed that compared with model group, p-eNOS protein and NO levels were increased in Z-GL groups(P<0.05 or P<0.01). CONCLUSIONS:Z-GL can significantly im-prove coagulation and vascular endothelium functions of blood-stasis model rats,and its mechanism may be associated with the acti-vation of eNOS and the increase of NO level.

Objective:To study the effects and mechanisms of acetyl-11-keto-β-boswellic acid ( AKBA) in myocardial ischemic model induced by isoproterenol hydrochloride ( ISO) in rats. Methods:The SD rats were randomly divided into the sham group, model group, AKBA low dose group and AKBA high dose group. Myocardial injury model was induced by subcutaneous injection of ISO (100 mg·kg-1 ) . The change of ST segment in ECG was observed. Creatine kinase ( CK-MB) , cardiac troponin I ( cTnI) , lactate dehydro-genase( LDH) , malondialdehyde( MDA) and superoxide dismutase( SOD) in the blood were detected by ELISA. The change of histo-logical tissue was determined by HE staining, and cell apoptosis was analyzed by TUNEL assay. Results: Serum CK-MB, cTnI and LDH were decreased significantly in AKBA high dose group when compared with those in the model group. Compared with that in the model group, MDA content was lowered and the SOD activity was increased in AKBA high dose group. Furthermore, AKBA high dose group improved the pathologic changes of myocardium. TUNEL assay revealed significant reduction of cardiomyocytes apoptosis in the hearts of the ischemic rats in AKBA high dose group. Conclusion:AKBA has excellent cardioprotective effect on myocardial ischemic induced by ISO and protection of myocardial cells from injury.

Objective To study the relationship of plasma aeylation stimulating protein (ASP) with complement C3, C-reactive protein (CRP) and blood lipid levels in women with polyeystic ovary syndrome (PCOS). Methods Thirty-four patients with PCOS were divided into two groups: obese PCOS group [body mass index (BMI)≥25 kg/m2] and non-obese PCOS group (BMI<25 kg/m2). 41 age-matched non-PCOS women were also divided into two groups: simply obese group (BMI≥25 kg/m2) and non-obese control group (BMI <25kg/m2). Plasma ASP in the 4 groups was detected by enzyme linked immunosorbent assay (ELISA) method.Complement C3 and CRP were determined by immunoturbidimetrie assay. Plasma free fatty acid (FFA)concentration was determined by colorimetric enzymatic assay, plasma triglycerides (TG) by GPO-PAP method and total cholesterol (TC) by COD-PAP method. Results The plasma ASP were significantly increased in the obese PCOS group, the non-obese PCOS group and the obese group as compared with the control group [(36.4±10.9,34.8±9.9, 35.1±14.0, 24.8±7.8) nmol/L, respectively, all P<0.05]. The concentrations of complement C3 were significantly higher in the obese PCOS group and the obese group than that in the control group [(2.2±1.2,2.5±1.5, 1.1±0.7) g/L, respectively, bothP <0.05]. The concentrations of CRP were significantly increased in the obese PCOS group, non-obese PCOS group and obese group as compared with the control group [(32.1±29.2, 30.0±24.8, 23.8±5.5, 7.5±4.8)mg/L, respectively, all P<0.05]. Univariate analysis showed that both plasma ASP and C3 were positively correlated with BMI, CRP, FFA and TG. CRP was positively correlated with BMI, FFA, TG and TC. Conclusion Plasma ASP, C3 and CRP levels in women with PCOS axe increased. They are strongly associated with disturbed lipid metabolism. The lack of association between ASP and complement C3 suggests that the conversion of C3 to ASP may be affected by other factors.

Objective:To establish two differential gene expression profiles of qi-deficiency and blood stasis syndrome before or after safflower injection treatment by using gene chip technology;compared and analyzed to ensure the effective genes that are responsible for the therapeutic effects of safflower injection against qi-deficiency and blood stasis syndrome in rats.Furthermore,speculated the effect mechanism of the therapeutic genes.Methods:Fifteen SD rats were randomly divided into 3 groups (n=5):control group,model group,and medication group.Qi-deficiency and blood stasis model was established by subjecting the rats to hunger and fatigue for two weeks.After a week of the modeling,safflower injection (100 mg/kg/d) was administered daily via the tail vein for 7 days in medication group,and the rats in model group were injected with saline of the same volume.Control group received normal feeding.At the end of the experiment,rats were killed and whole blood was collected to evaluate the blood stream change and extract mRNAs in blood samples.Qualified mRNAs were reverse transcribed into cDNA which was then used in gene chip hybridization.The genes regulated by safflower injection were determined by the fluorescence signal and the functional mechanisms of safflower injection were confirmed by further querying genealogy databases and reviewing literatures.Results:After two weeks of the modeling,the whole blood viscosity under various shear rates was significantly increased in the model rats which showed faint,blood stasis and weight loss,indicating that the model is made successfully.The increased whole blood viscosity and qi-deficiency and blood stasis syndrome were obviously reversed by safflower injection treatment.Compared with the control group,252 genes up-regulated while 54 genes down-regulated in model group;compared with the model group,196 genes up-regulated while 32 genes down-regulated.Among these,16 differentially expressed genes were involved in inflammation and immune response.Conclusions:Safflower injection was effective in treating qi deficiency and blood stasis syndrome,which was achieved by regulating inflammation related genes.

Objective To evaluate global and segmental right ventricular ( RV ) systolic functions in patients with excessive volume or pressure load using real‐time three‐dimensional echocardiography ( RT‐3DE) . Methods Forty‐five patients with RV volume overload ,45 patients with RV pressure overload and 45 healthy subjects were underwent RT‐3DE . RV global and segmental ( inflow ,body ,outflow ) end‐diastolic volume (EDV) ,end‐systolic volume (ESV) ,stroke volume (SV) and ejection fraction (EF) were analyzed with TomTec software . The correlations between EF with the three‐dimensional method and two‐dimensional parameters including right ventricle systolic pressure( RVSP) were discussed . Results Global EDV and ESV increased significantly in both patient groups compared with controls ( all P < 0 .05) ,but there was no difference between two patient groups ( P >0 .05) .Compensated increase of SV was found in sixty percent of patients with volume overload but none with pressure overload ( P < 0 .05) . Global EF decreased significantly in both of patient groups (all P <0 .05) ,which was more significant patients with pressure overload ( P < 0 .05 ) . Different patterns of the regional dysfunction were found among the different RV segments . No correlation was found between RVSP and global or segmental EF in patients with pressure overload . Conclusions RT‐3DE could be used to assess global and segmental RV systolic function in patients with pressure and volume overload .

Objective To improve the technology of retroperitoneal laparoscopic living donor nephrectomy and observe its clinical effect.Methods Forty-one cases of living donors subject to nephrectomy by the new retroperitoneal laparoscopic technique from July 2009 to June 2012 were retrospectively.The new technique was modified as follows: (1) Alternate use of blunt dissection,sharp dissection and harmonic scalpel; (2) After separation of renal vein,artery and ureter,a 5-6 cm incision parallel to rectus abdominis from Trocar was made in order to put a hand inside retroperitoneum; (3) A biopsy of the kidney was made from Trocar with the help of a hand for holding the kidney; (4) Pulling the kidney with a proper strength and blocking renal artery and renal vein with Hem-o-lock,then cutting off them and taking out the kidney.Results Forty-one cases of live donors subject to nephrectomy were operated on successfully,and were not converted to open operation.The operative time was 65-130 min (mean 85 min).The warm ischemia time was 58-110 s (average 78 s).Living donor kidney artery length was 2.1-3.7 cm (average 2.9 cm).Living donor kidney vein length was 2.5-4.1 cm (average 3.5 cm).Blood loss was 15-80 ml (average 28 ml).Hospital stay after surgery was 4-7 days (average 4.8 days).All biopsy specimens were achieved from 41 cases.None suffered from complications except two cases of perilymphorrhea.Forty-one recipients recovered well after renal transplantation.Conclusion The improved retroperitoneal laparoscopic living donor nephrectomy is considered to be safe,effective and feasible.It is a good way to protect renal function and reduce injury.

Objective To study the effect of RNA interference on the expression of CTGF in skin fibroblasts of systemic sclerosis(SS). Methods Four CTGF specific siRNAs and a negative control siRNA were designed and then synthesized by in vitro transcription. siRNAs labeled with carboxyfluorescein-6-succimidyl ester (FAM) were transiently transfected into SS skin fibroblasts. Forty-eight hours after the fibroblasts were treated with siRNAs, the mRNA and protein expression of CTGF was detected by semiquantitative RT-PCR and Western blot analysis, respectively. Results The mRNA and protein expression of CTGF in fibroblasts was significantly down-regulated by 4 and 3 CTGF specific siRNAs (both P

Objective To investigate the effect of phorbol-12-myristate-13-acetate(PMA)on cyclooxygenase-2(COX-2) mRNA and protein expression in cultured human HaCaT keratinocytes,and the mechanism for cytotoxity of PMA against keratinocytes.MethodsRT-PCR and Westem blot were utilized to detect the expression of COX-2 mRNA and protein in cultured HaCaT ells at 24 hours after the treatment with various concentrations of PMA (0.1,1.0,10 mg/L).ResultsWithout any treatment,there was no or a weak expression df COX-2 mRNA and protein in HaCaT cells;incubation witll PMA resulted in the induction of the expression of COX-2 in HaCaT cells.The expression levels of COX-2 mRNA and protein in 10 mg/L PMA-pretreated HaCaT cells were significantly higher than those in 1.0 mg/L PMA-pretreated HaCaT cells,which was in turn higher than that in 0.1 mg/L PMA-pretreated cells and untreated cells;the difrerence was statistically significant (all P＜0.01).Conclusion These results suggest that PMA may be involved in keratinocyte tumorigenesis by upregulating he expression of COX-2 as well as synthesis and release of prostaglandin in keratinocytes.
