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.

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.

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 .

AIM: To discuss the tongxinluo supermicropowder's interventional effect on aorta endodermis of rabbits which are fed with fatty forage plants.METHODS: Thirty-two healthy male New Zealand rabbits were divided into 4 groups randomly: control group,model group,atorvastatin treatment group,and tongxinluo treatment group.The control group was fed with common feedstuff,and all the other groups were fed with fatty feedstuff.The atorvastatin treatment group and the tongxinluo treatment group were given suspension of atorvastatin(3 g?kg-1?d-1) and tongxinluo supermicropowder(0.31 g?kg-1?d-1) by intragastric administration on the basis of fatty feedstuff.All the groups were fed with medicine for 6 weeks.At the end of 6 weeks,blood lipid levels were observed by enzymic method,the levels of blood serum NO and MDA and the activity of SOD were observed by chromatometry,the expression of nuclear factor-kappaB(NF-?B),intercellular adhesion molecule-1(ICAM-1) was detected,and VCAM-1mRNA expression in the aortic tissue was examined by reverse transcription polymerase chain reaction(RT-PCR).RESULTS: The levels of blood serum TC,TG,LDL-C,HDL-C,and MDA were increased significantly compared with the control group(P

AIM: To observe the different changes of neuroendocrine systems between the state of sport fatigue and poverty of movement. METHODS: 60 male Wistar rats were randomly divided into three groups: normal control group, sport fatigue model group and poverty of movement model group (20 rats in each group). The sport fatigue model was established by the method of combining basal diet and loaded swimming during 2 weeks, whereas the method of restricted activities was used to establish the poverty of movement model with total experimental time of 10 weeks. By the end of experiment, the climbing pole time was determined. The contents of hypothalamus thyrotropin releasing hormone (TRH), and serum norepinephrine (NE) and epinephrine (E) in rats with different treatments were determined by ELISA. In addition, the changes of hypothalamus corticotropin release hormone (CRH), pituitary adrenocorticotropic hormone (ACTH) and thyroid stimulating hormone (TSH), and serum corticosterone (CORT), triiodothyronine (T_3), tetraiodothyronine (T_4) were determined by radioimmunoassay to evaluate the functions of adrenergic nerve-adrenomedullin system, hypothalamo-pituitary-adrenal (HPA) axis and hypothalamo-pituitary-thyroid (HPT) axis. RESULTS: Compared to control group, the climbing pole time of the animals was obviously decreased in two model group. The adrenergic nerve-adrenomedullin system and HPA axis were inhibited in sport fatigue model rats, but HPT axis was unchanged. Interestingly, the HPA axis was hyperfunctional and HPT axis was inhibited in poverty of movement model rats. However, no change in the adrenergic nerve-adrenomedullin system was observed. CONCLUSION: Sport fatigue and poverty of movement all affect neuroendocrine system and lead to the adjustment mechanism imbalance, but the target and tendency are different.

OBJECTIVE To study the changes in matrix metalloproteinase-9 (MMP-9) mRNA, tissue-inhibitor of metalloproteinase-1 (TIMP-1) mRNA and the ratio of MMP-9 mRNA/TIMP-1 mRNA in the lungs of paraquate poisoning rats, and to investigate the protective effects of sodium dimercaptopropane sulfonate (DMPS, Unithiol). METHODS One hundred and twenty male SD rats were divided into 12 groups (n=10) randomly: normal control, DMPS control, PQ poisoning 1, 3, 7, 14 and 28 d model groups, (DMPS+PQ) 1, 3, 7, 14 and 28 d groups. PQ poisoning model was established by intraperitoneal injecting paraquate. The expression of MMP-9 mRNA and TIMP-1 mRNA in lung tissues was detected by RT-PCR. RESULTS ①By observing the changes of action and observing the lung tissues sections, the rats' PQ poisoning models was successfully established. ②The histopathology of lung showed infiltration of inflammatory cell in acute phase(within 2 weeks), the inflammation decreased gradually after 2 weeks, hyperplasia of collagen and pulmonary fibrosis were instead. Howerer, the pathological changes were alleviated obviously in the (DMPS+PQ) groups. ③Compared with the PQ groups, the expression of MMP-9 mRNA and TIMP-1 mRNA in lungs diminished greatly in the DMPS+PQ groups after rats injected DMPS(P<0.05); the ratio of MMP-9/TIMP-1 mRNA was bigger at 7, 14 and 28 d in the DMPS+PQ groups after rats injected DMPS. CONCLUSION Down-regulation of the expression of MMP-9 mRNA and TIMP-1 mRNA and up-regulation ratio of MMP-9 mRNA/TIMP-1 mRNA by DMPS may be one of mechanisms by which pulmonary injury and pulmonary fibrosis are prevented in the acute paraquate poisoning.
