Objective To observe the clinical efficacy of integrated traditional Chinese and western medicine in the treatment of infertility resulted from ovulation dysfunction.Methods 106 patients with ovulation dysfunction were divided into observation group(n =56)and control group(n =50)in stratified randomization.Both two groups were given clomiphine to induce ovulation.Futhermore,the observation group was added Chinese herb recipe.Both two groups were treated for 3 menstruations.The basic body temperature,follicle development,endometrium depth, ovulation and pregnancy were observed.The serum levels of E2,LH and FSH were detected.Results There was no difference in the basic body temperature between the two groups(P >0.05).After treatment,the basic body tempera-ture of the observation group was obviously superior to that of the control group(χ2 =0.627,P =0.049),there was no difference in the endometrium depth between the two groups(P >0.05).After treatment,the endometrium in the observation group was significantly better than before treatment and that in the control group(t =5.132,P <0.05). After treatment,the serum levels of E2 ,LH and FSH in the observation group were all improved more obviously than those in the control group(t =6.489,5.167,6.035,all P <0.05).The efficacy of the two groups was higher than that of the control group(χ2 =6.049,P =0.048).Conclusion The method of integrated traditional Chinese and western medicine can promote the development of follicle and endometrium,improve levels of E2,LH and FSH,enhance ovula-tion rate and pregnancy rate in the treatment of infertility resulted from ovulation dysfunction,which is worthy of clini-cal promoting.

The high mortality of paraquat (PQ) poisonings is mainly due to the lack of effective treatments. The optimal method of extracorporeal removal of paraquat is often a matter of debate. Due to the lack of well-designed studies, we are often left with circumstantial evidence, and we must exercise our best clinical judgment as to whether extracorporeal paraquat removal is beneficial and if so, by what method. It is clear, however, that rapidity in paraquat removal is beneficial. Due to the urgent nature of treatment for paraquat poisoning, there may never be well-designed evidence-based studies to help guide us. In the meantime, we must continue to use less than ideal evidence and our own experience to guide our decision-making process. Most toxicologists recommend rapid initiation of charcoal haemoperfusion (CHP) to lower plasma PQ levels and to limit pulmonary and other organs uptake of PQ.

Objective To develop a rapid, accurate, specific method to detect causative agent of hand, foot and mouth disease (HFMD). Methods Specific primers and probe were designed based on highly conserved VP1 region of enterovirus 71, coxsackie virus A16 and enterovirus. The sensitivity and specificity of the real-time RT-PCR was evaluated with 35 stool samples collected from pediatric patients with suspected HFMD and 20 clinical samples from health pediatric patients. Results Out of 35 clinical samples from suspected HFMD, 35 samples were identified as positive for enterovirus, 25 clinical samples were identified as positive for enterovirus 71, 8 clinical samples were identified as positive for coxsackie virus A16, among which 3 clinical samples were identified as positive for enterovirus 71 and coxsackie virus A16. The clinical diagnostic accordance rate is 85.71%. Out of 20 clinical samples from normal pediatric patients, 5 clinical samples were identified as positive for enterovirus, 20 clinical samples were negative for enterovirns 71 and coxsackie virus AI6. Conclusion Our results indicate real-time RT-PCR offers a rapid, sensitive, specific and cheap method to detect pathogen of HFMD from clinical specimens.

ObjectiveTo study the efficacy of different doses of tamsulosin hydrochloride sustained release tablets for treatment of premature ejaculation (PE). MethodsEighty PE patients from September 2010 to January 2011 were divided into two groups randomly,the 0.2 mg dose group and the 0.4 mg dose group.The therapeutic effect was assessed by the changes of the patients' CIPE-5 scores.ResultsThe intra-vaginal ejaculation latency time (IELT) of the two groups were (0.98 ± 0.47 ) and ( 0.89 ± 0.47 ) min respectively before treatment,and (4.40 ± 1.86 ) and (6.40 ± 5.10) min respectively after treatment.There were significant differences ( P ＜ 0.01 ).As for satisfaction degree of sexual life,lessening the patients' sexual anxiety and nervousness,and decreasing the difficulty in retarding ejaculation,the group of 0.4 mg had better effect than the other group.ConclusionLarge dose of tamsulosin hydrochloride sustained release tablets could prolong IELT and increase the sexual satisfaction.

BACKGROUND:Clinical infusion of hematopoietic stem cells and mesenchymal stem cells for treatment of aplastic anemia has been reported. OBJECTIVE:To investigate the effect of human adipose-derived mesenchymal stems cells on the secretion function of T lymphocytes of aplastic anemia patients. METHODS:Human adipose-derived mesenchymal stems cells were extracted from healthy human adipose tissues. T-lymphocytes were harvested from peripheral blood of patients with aplastic anemia by density gradient centrifugation. Human adipose-derived mesenchymal stems cells were co-cultured with T-lymphocytes. The levels of interleukin-2, interleukin-4, interleukin-10 and interferon-γwere detected by enzyme linked immunosorbent assay. T-bet and GATA-3 levels were examined by real-time PCR and western blot. RESULTS AND CONCLUSION:The levels of Th1 type cytokines interferon-γand interleukin-2 in the co-culture group were significantly lower than those in the T-lymphocyte group (P<0.05). But the levels of Th2 type cytokines interleukin-4 and interleukin-10 in the co-culture group were significantly higher than those in the T-lymphocyte group (P<0.05). The T-bet mRNA and protein levels in the co-culture group were significantly lower than those in the T-lymphocyte group, while the GATA-3 mRNA and protein levels were significantly higher in the co-culture group. Human adipose-derived mesenchymal stems cells can mediate an immunoregulation effect on T-lymphocytes of aplastic anemia patients in vitro, which is possibly related with the inhibition of Th1-dominant response due to the disorder of T-bet and GATA-3 gene expression.

Objective To investigate the value of integrin αvβ3 targeted microSPECT/CT imaging with 99 Tcm-3P4-RGD2 as a radiotracer in tumor anti-angiogenesis therapy .Methods Animal models bearing glioma and prostate cancer xenografts were established by subcutaneously injecting tumor cells U87MG and PC-3 in nude mice.Anti-angiogensis therapy with Avastin was administered via intraperitoneal injection when the tumor diameter reached 6 to 7 mm while saline was served as control group . MicroSPECT/CT imaging was performed with 99 Tcm-3P4-RGD2 as radiotracer one day before and 3, 5, 10, 15 days after Avastin administration .Tumor volume and tumor uptake of 99 Tcm-3P4-RGD2 , expressed as percentage of injected dose (%ID) or %ID per gram (%ID/g) were measured and calculated based on microSPECT/CT.Mice basic condition was monitored and tumor xenograft was harvested in one tumor bearing nude mouse after its sacrifice at each imaging time point .Results Tumor volume of U87MG glioma in the administration group was significantly smaller than that of non-administration control group at 10 d after Avastin adminstration ( t=5.81, P<0.05), while no significance was observed between the administration group and its control group of PC-3 tumor (P >0.05).The uptake of 99Tcm-3P4-RGD2 (%ID/g) in U87MG group was higher than that in PC-3 group before Avastin administration ( t=10.48, P<0.05), and it decreased to a value less than control ( t =3.26, P <0.05) at 3 d after Avastin administration and continually reduced at longer time after administration .PC-3 tumor had less uptake of 99 Tcm-3P4-RGD2 in both Avastin administration group and its control group .The pathologic results revealed on that the decrease of tumor integrin β3 expression in U87MG treatment group was mainly on the endothelial cells of the neovessel .Linear relationship was verified between tumor uptake (%ID/g ) and integrin β3 expression (y=0.499 1x-0.243 8, R2 =0.811 7).Conclusions Complete inhibition of integrin is demonstrated early after Avastin administration .99 Tcm-3P4-RGD2 microSPECT/CT imaging, assessing the expression level of integrin αvβ3 level by quantification of tumor uptake of 99 Tcm-3P4-RGD2 , is probably an important method to reflect the early therapeutic effect of tumor anti -angiogensis .

Objective To investigate the effects of enteral nutrition via the nasojejunal and nasogastric feeding on stroke-associated pneumonia (SAP) and other complications in patients with severe acute stroke.Methods A total of 60 patients with severe acute stroke who needed tube feeding were randomized to either a nasojejunal tube group or a nasaogastric tube group for enteral nutrition support.The occurrence of SAP,diarrhea,vomiting,and gastrointestinal bleeding within 2 weeks were observed.The nutrition indices (total protein,prealbumin,and hemoglobin) before and at day 7 and 14 after the tube placement were documented and compared.Results There were 30 patients in the nasojejunal tube group and the nasaogastric rube group,respectively.There were no significant difference in demographic and baseline clinical data between the 2 groups.The incidence of SAP (43.3％ vs.70.0％;x2 =4.340,P=0.037),vomiting (13.3％ vs.43.3％;x2 =6.648,P =0.010),and hyponatremia (6.7％ vs.40.0％;x2 =4.022,P =0.045) in the nasojejunal rube group were significant lower than those in the nasogastric rube group,however,there was no significant differences in the incidences of diarrhea and gastrointestinal bleeding.Compared with before indwelling tube,there were no significant difference in the concentrations of total plasma protein and prealbumin at day 14 after indwelling tube in the nasojejunal tube group,but the concentration of hemoglobin were decreased significantly (P =0.001);compared with before indwelling tube,the concentrations of the total plasma protein (P =0.001),prealbumin (P =0.036),and hemoglobin (P =0.001) at day 14 after indwelling tube in the nasogastric rube group were significantly decreased.Conclusions Nasojejunal nutrition may effectively prevent SAP,volmiting,and hyponatremia in patients with severe acute stroke,and contributes to maintain the nutritional status.

Objective To compare transdermal penetration of triamcinolone acetonide liposparticles (TAA-LPPs) and TAA-Ethosomes in vitro. Methods The TAA-LPPs and TAA-Ethosomes were produced and the morphology was observed by transmission electron microscope,particle size was detected by laser particle analyzer. The percutaneous permeability in vitro was tested by modified Franz diffusion pools. The amount of penetrated triamcinolone acetonide and the retention in the skin were de-termined by HPLC. Results The shape of TAA-LPPs and TAA-Ethosomes was almost spherical with mean diameter of (99. 9±1. 3) and (105±1. 4) nm, respectively. The cumulative transdermal penetration of TAA-LPPs, TAA-Ethosomess and TAA suspension was (53. 59±4. 40),(87. 03±4. 87),and (30. 54±8. 61) μg·(cm2 ) -1 , respectively . The drug retention in the skin after 32 h was (1. 02±0. 13), (0. 62±0. 08), (0. 55±0. 17) μg·(cm2 ) -1 , respectively. Conclusion TAA-LPPs is better for transdermal administration of triamcinolone acetonide by reducing systemic absorption of the drug.

Aim To study the effect of (S) -1, 8-(2-methyl phosphate ethoxy )-6-fluorine-7-( 4-methyl- pi-perazine-1-base )-3-[ S-benzyls-based-4-( for nitroben-zene methylene group amino )-1 , 2 , 4-all triazole-3 base]-quinoline ( 1-H )-4-ketone ( M18 ) on apoptosis of hepatocarcinoma SMMC-7721 cells in vitro. Meth-ods With different concentrations of M18 at different time used to treat SMMC-7721 cells, human breast cancer MB-231cells, human colon cancer HCT-116 cells, human hepatocarcinoma HEPG-2 cells, mouse bone marrow mesenchymal stem cells ( BMSCs ) in vitro,the inhibition effects of M18 on cell proliferation were examined by MTT assay. Cell apoptosis was de-termined using Hoechst 33258 fluorescence staining and TUNEL method. Mitochondrial membrane poten-tial (△ψm ) was measured using a high content screening image system. Protein expression of caspase-3 , p53 and cytochrome C was detected with Western blot analysis. Results Treatment with M18 ( 4 ~32μmol·L-1 ) potently inhibited the proliferation of the cancer cells in time-and dose-dependent manners ( the IC50 value at 24 h in SMMC-7721 cells, MB-231cells,
HCT-116 cells and HEPG-2 cells was 8. 65 μmol · L-1 , 9. 37 μmol · L-1 , 12. 74 μmol · L-1 and 9. 40μmol · L-1 , respectively ) . In contrast, M18 had weak cytotoxicity against BMSCs with IC50 value of 38. 96 μmol·L-1 . Levofloxacin had weak cytotoxicity against SMMC-7721 cells with IC50 value of 735. 10μmol·L-1 . Treatment of SMMC-7721cells with differ-ent concentrations of M18 for 24 h increased the per-centage of the apoptosis cells ( P <0. 05 ) and de-creased the mitochondrial membrane potential. In ad-dition, M18 increased protein expression of p53, caspase-3 and the cleaved activated forms of caspase-3 in SMMC-7721 cells. Treatment of SMMC-7721 cells with M18 significantly increased cytochrome C in the cytosol, and decreased cytochrome C in the mitochon-drial compartment. Conclusion The mitochondrial-dependent pathways are involved in M18 induction of apoptosis of SMMC-7721 cells.
