Female stress urinary incontinence (FSUI) is a common disease of women in department of urology, which severely affects elderly physical and mental health of women. The molecular mechanism of FSUI is still unclear. Nitric oxide synthase (NOS), cyclooxygenase (COX) and their respective products nitric oxide (NO) and prostaglandin (PG) are closely related with FSUI. In this paper, the distribution of NOS and COX in female lower urinary tract and the research development of NOS, COX and their products with FSUI are summarized.

Multiple myeloma (MM) is malignant plasma cell clonal disease.Autologous stem cell transplantation (ASCT) strengthen the advantages of the high-dose chemotherapy in treatment of MM,which achieves long-term survival in some patients.Even in the era of targeted novel agents,ASCT can still obviously increase the response rate of treatment.To improve the therapeutic efficacy,targeted novel agents were administrated before and after ASCT.However,targeted novel agents still cannot replace ASCT therapy in the treatment of MM.The direction of future research is to find more reasonable,effective and low toxic treatment.

Current concerns for the diagnosis of functional gastrointestinal disorders (FGIDs) in clinical practice is reviewed in this paper.They include the principle to exclude the organic diseases,a full recognition of subtype classification and the severity degrees in guiding the treatment,role of gastrointestinal function examination in diagnosis and treatment,influence of psychological factors on disease,and the overlapping phenomenon of functional disease with organic diseases.

Spermatogenesis is a complex process. Current knowledge about human spermatogenesis is mainly based on the mouse model while little is known about the initial stage of this fundamental process in humans. The establishment of the model of spermatogenesis in vitro may contribute to an overall understanding of male germ cell development, an insight into the mechanisms of infertility, and clinical management of male infertility. This review summarizes current knowledge about the generation of germ cell-like cells from induced pluripotent stem cells (iPSCs) in vitro and discusses the potential application of iPSCs in the treatment of male infertility.

Continuous renal replacement therapy has become an important organ support method for children with liver failure.Anticoagulation is a key step in determining the success of this treatment.Traditional systemic heparin anticoagulation has a high risk of inducing thrombocytopenia and bleeding.Protamine antagonistic heparin local anticoagulation performance is unsatisfactory.Anticoagulation without heparin is difficult to develop smoothly in children, especially low-weight infants.In recent years, regional citrate anticoagulation has gradually received attention as a new type of anticoagulation.This article reviewed the clinical application of this anticoagulation technology.

Objective: To determine ? asarone and ? asarone in Rhizoma acori tatarinowii(RAT) . Methods: HPLC condition consists of ODS C 18 column(150mm?4.6mm, 5?m), methanol: water(6∶4) as mobile phase containing potassium dihydrogen phosphate 1.4g and sodium lauryl sulfate 1.2g per 1000mL, detective wavelength at 257nm, flow rate at 1.0mL?min -1 . Results: For RAT the mean recovery of 99.02%( RSD =1.03%) for ? asarone, 101.26%( RSD =3.57%) for ? asarone are obtained, respectively. Conclusion: The method is sensitive, rapid and accurate.

Objective Hypotension can be induced by sodium nitroprusside(SNP) combined with propofol more easily and with less amount of each drug. But both SNP and propofol were reported to inhibit platelet aggregation. The purpose of present study was to investigate the effect of controlled hypotension induced by SNP alone or in combination with propofol on human platelet aggregation. Methods Fifty-six ASA Ⅰ -Ⅱ patients (30 male, 26 female), aged 20-54 (36.0 ? 11.2) years and weighing 42-79 (67.6?14.3)kg, undergoing elective neurosurgery were randomly assigned to one of four groups: A control group ( n = 14) ; B propofol group ( n = 14) ; C SNP group( n = 14) and D SNP + propofol group ( n = 14) . The patients were premedicated with luminal 0.lg and atropine 0.5 mg. Anesthesia was induced with midazolam 0.2 mg ?kg-1 , fentanyl 5 ?g?kg-1 and vecuronium 0.1 mg?kg-1 and maintained with isoflurane inhalation and intermittent boluses of fentanyl and vecuronium. In group A and B no hypotension was induced. In group C and D hypotension was induced by 0.01 % SNP infusion (0.5-5 ?g?kg-1?min-1 ) alone or combined with propofol infusion(2-3 mg?kg-1?h-1 ) . As soon as the dura was cut, hypotension was induced. MAP was reduced by 30 % and maintained at ( 67.80 ? 9.64 ) mm Hg on average. Radial artery was cannulated for continuous BP monitoring. In order to avoid the effect of colloid and homologous transfusion on platelet function, only Ringer' s lactate was infused during operation in the four groups. Blood samples were taken from peripheral vein before skin incision, 30min and 1h after hypotension was induced and 2h after surgery for determination of platelet aggregation, prothrombin time and plasma level of NO2 -/NO3- .Results Platelet aggregation was significantly inhibited in group C and D at 30 min and Ih after induction of hypotension as compared with the baseline (before operation) . There was significant difference in the inhibition of platelet aggregation among the four groups. The inhibition was greatest in group D. There was no significant change in prothrombin time after induction of hypotension in the four groups. Plasma level of NO2-/NO3 - increased significantly at 30 min and 1h after induction of hypotension in group C and D. Conclusions SNP combined with propofol has inhibitory effect on human platelet aggregation during controlled hypotension and increased in plasma NO2 -/NO3-level may be the mechanism.

Objective To investigate the effects of propofol on lung nitric oxide synthase (NOS) in rats and the mechanism of its pulmonary artery and bronchus dilating effects. Methods Forty SD rats weighing (210+40)g were randomly divided into two groups: propofol group received propofol 100mg-kg-1 ip and when its righting reflex was lost propofol was continuously infused at 10mg'kg-1 h-1 through the vein in the tail for 10min, then the animal was killed; control group received normal saline 10 ml'kg-1 ip and the animals were killed 20 min later. After sacrificing the animals the chest was opened and the lungs were removed. The NO level in the broncho-alveolar lavage fluid (BALF) was measured in 10 animals. NOS activity and NO content of the lung tissue homogenate were examined in 10 animals. Cellular distribution and expression of endothelial NOS (eNOS) and neural NOS (nNOS) in the lung were examined by immunohistochemistry in 5 animals. Results The NO level in BALF, NO content and NOS activity in the lung homogenate were significantly higher in propofol group than those in control group (P

Objective: To determine the component of naphtha from Acorus tatarinowii Schott.which can pass through the blood-brain barrier. Methods: Naphtha in rat brain was analyzed by GC-MS after gastric infusion of naphtha. Results: The methylisoeugenol,elemicin, ?-asarone and ?-asarone were detected in rat brain. Conclusion: The resuscitative effect of naphtha is resulted from the comprehensive action of multiple components.
