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 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.

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.

0.05),the content ratio of glutamate to gamma-aminobutyric acid in the hippocampus of the dependent rats was lower than that in the control group(P

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.

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.

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.

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 evaluate the utility of modified Z-stent in treatment for Budd-Chiarisyndrome (BCS). Methods A retrospective study was used in twelve BCS patients treated in twohospitals. The Doppler examination was carried out in all patients preoperatively, so as to confirm thenature of the lesion and chose correct type of endovascular modified Z-stent. Under DSA monitoring formembranotomy and dilation of the inferior vena cava(IVC), after that, insert the marked modified Z-stent to IVC correctly, and put the non-stent part to hepatic vein orifice. The cavography and hepaticvenography should confirm the position of the Z-stent. All of 12 patients with membranous obstructionof the IVC(MOVC) or segmental obstruction of the IVC (SOVC)were underwent modified Z-stentplacement. Results The IVC pressure (IVCP) before smd after membranotomy (dilation) were 27.33± 4.12cmH2O and 18.67 ± 5.07cmH2O (P＜0.01). Comparing with dilation and putting stent group,the IVCP decreased from 18.67 ± 5.07cmH2O to 11.42 ± 2.11 cmH2O ( P ＜ 0.01 ). The modffied Z-stent could avoid hepatic vein orifice getting compression and resist the retraction of IVC throughly infollowing-up period of 2.5 years. Conclusion s The endovascular treatment of BCS with modified Z-stent is more effective and safer to prevent thrombosis. Further study will be required to observe theirlong term effects.
