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.

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.

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.

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.

AIM To discuss the effects of losartan on AT 1R mRNA expression and renin angio tensin system (RAS) level in brain of spontaneously hypertensive rat (SHR). METHODS Sixteen 6 week old male SHR and 16 sex and age matched WKY were divided into losartan ( n =8) and control groups ( n =8) respectively. Losartan (30 mg?kg -1 ?d -1 ) or equal volume of 0.9% saline solution was administered for 18 weeks by gavage. AT 1R mRNA expression was examined by reverse transcription polymerase chain reaction (RT PCR). Renin activity (RA) and angiotensinⅡ(AngⅡ) levels were measured by radio immunoassay. Angiotensin converting enzyme activity (ACEA) was measured by ultraviolet spectrophotometar. RESULTS Enhanced brain AT 1R mRNA expression was found in SHR compared with WKY ( P 0.05, respectively). CONCLUSION The increase of AT 1R mRNA expression and RAS levels in brain may be involved in the pathogenesis of hypertension in SHR. Losartan protects brain by decreasing expression of brain AT 1R mRNA.

Objective To study the clinical significance of detection of infectivity index in patients before transfusion. Methods A total of 12 863 patients in hospital were examined for hepatitis B virus surface antigen(HBsAg),anti-hepatitis C virus(anti-HCV),anti-AIDS virus(anti-HIV)and treponemiasis test(TRUST)before operation and transfusion. Results The positive rates of HBsAg,anti-HCV,anti-HIV and TRUST were 12.59%,1.90%,0.02%and 0.80%respectively.Conclusion The detection of infectivity index before transfusion has a very,important role in the prevention of blood transmissible disease and reduction or medical treatment dispute caused by infection after transfusion.

Objective To investigate the nursing intervention of pregnant women with antiphespholipid syndrome(APS). Methods In experimental group 40 cases with APS positive and control group 40 cases with APS ACA-negative for comparison. Results The abortion occurred in 6 cases(15. 0%) ,2 cases of stillbirth(5.0%) ,loss of pregnancy(abortion+stillbirth) 8 cases (20. 0%) in experimental group. The abortion occurred in 2 cases (5.0%), no stillbirth in control group. The loss of pregnancy in experimental group were significantly higher than the control group (X2=9. 54, P＜0. 005 ). The rate of positive in ACA-IgG (40. 0%) after treatment lower than before treatment (52. 5 %) (X2 = 3.85, P＜0. 05). The rate of positive in ACA IgM (37. 5%) after treatment lower than before treatment(40. 0)% (X2=3.81 ,P＜0. 05 ). Conclusion The APS positive rate and the loss of pregnancy were closely related. The overall nursing intervention conld improve efficacy and reduce the complications.

Objective To investigate the efficacy to pregnant outcoule with antieardiolipin antibody(ACA) of qualitative and quantitative before treatment and after treatment in women pregnant with antiphospho-lipid syndrome (APS).Methods The heparin combined with aspirin therapy APS 40 patients before and after treatment to momtor the change of ACAIgG,IgM.Results 40 patients were treated 37 eases of live births,success rate were92.5%,the rate of pregnancy loss were3 cases(7.5%);The lever of ACA-IgG and ACA-IgM were(67.63±2.53)u and (49.40±3.64)u beforetreatment andlever of ACA-IgG and ACA-IgM were(23.87±1.54)u and(21.60±2.59)u after treatment.The lever after treatment were significandy Iower than the before treatment(P＜0.01);The level of ACA were overall downward in 40 cases after treatment by dynamic observation;The rate of positive in ACAIgG (40.0)% after treatment lower than before treatment(52.5)%(X2=3.85,P＜0.05);The rate of positive in ACA IgM(37.5)% after treatment lower than before treatment(47.5)%(X2=3.81,P＜0.05).Conclusion Hepfinar treatment combined with aspirinmay be a safe and effective method for patients with APS.

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.
