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.

?Silent information regulator protein 1 ( SlRT1 ) is a kind of histone deacetylases class lll on which cell metabolism coenzyme NAD+ is dependent. By the transcriptional regulation, it participates in the regulation of gene transcription, energy metabolism and cell aging process, which can prolong the lifespan of organisms and delay the development of various age-related diseases and has attracted much attention in the field of anti - aging research. ln recent years, studies have shown that SlRT1 occupies an important position in the pathogenesis of many ophthalmic diseases, especially in ocular surface diseases, glaucoma, cataracts, uveitis, and ocular fundus diseases, etc. There is a possibility that the promotion of SlRT1 activity would be the new drug target of ophthalmic therapy. The paper will review studies on SlRT1 and ophthalmic diseases.

Objective To make molecular diagnosis for puerile spinal muscular atrophy(SMA).Methods Genomic DNA was extracted directly from the blood of both the case group(10 children with SMA) and the control group(including 19 parents of SMA patients and 20 healthy individuals).Two methods,polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and allele-specific PCR,were used to analyze exon 7 of SMN gene from genomic DNA,and consequent electrophoresis of PCR products on agarose gel was performed.Results Genotyping results obtained by both methods were in complete agreement for all of the samples analyzed.In conventional PCR-RFLP,part of the PCR products(189bp) from genomic DNA of all 39 members in the control group remained intact after digestion with Dra I,while the PCR products from genomic DNA of all 10 SMA children in the case group was completely digested by Dra I.In allele-specific PCR,exon 7 of both SMN1 and SMN2 could be seen when genomic DNA of all 39 members in the control group was used,while only SMN2's exon 7 could be seen when genomic DNA of all 10 SMA children in the case group was used.Conclusion Homozygous deletion of SMN1 was present in all 10 SMA children in the case group,while homozygous deletion of SMN1 was not detected in all 39 members in the control group.The combination of PCR-RFLP and allele-specific PCR,both their results can be references for each other,offers efficient and accurate methodology for molecular diagnosis of SMA.

Objective To investigate the efficacy and safety of carvedilol in patients with chronic heart failure (CHF).Methods Forty-six patients with CHF were randomly divided into carvedilol group (n=26) and control group (n=20) on the basis of standard therapy including digitalis, diuretics and ACEI. Before and after treatment, NYHA class, echocardiography and adverse reaction were observed. Results The mean dose of carvedilol was titrated to 25.14?3.05mg/day. After treatment, NYHA class was improved in both groups. Left ventricular end-diastolic diameter (LVEDD) measured by echocardiography reduced [(58.79?8.99)mm vs (64.68?10.12) mm,P

Objective To study the feasibility of the treatment of tubule pregnancy by interventional technique. Methods By using Seldinger′s method, 40 cases of tubule pregnancy received superselective angiography of uterine artery,followed by perfusion of methotrexate (MTX) through the catheter and embolization of uterine artery with gelatin sponge. The concentration of serum ? HCG, the change of pelvic cavity, and the open condition of oviduct were regularly monitored postoperatively. Results Angiographic findings of tubule pregnancy were classified into 3 types. Type Ⅰ, no abnormal vascular appearance were found in 3 cases (7.5%). Type Ⅱ, patchy vascular staining of villi in parauterine area was observed in 4 cases (10.0%). Type Ⅲ, a round vascular staining of villi surrounded by small blood vessels in parauterine area occurred in 33 cases (82.5%). The cure rate in total 40 cases achieved 97.5% (39/40). After treatment, the mean time that the serum ? HCG concentration returned to normal was (7.66?2.01) d and the mean time that the menstruation returned to normal was (29.78?7.14) d. In 21 cases who hoped their fertility remaining intact, the oviduct were verified open by hysterosalpingography (HSG) in 20 cases, the open rate was 95.24%. Conclusion The treatment of tubule pregnancy by interventional technique was proved no harmful effect to reproductive organs and would expect to preserve fertility. This method could resolve the difficult problem of celiac hemorrhage which making conservative treatment impossible and internal hemorrhage happened in the course of traditional conservative therapy leading to treatment failure finally. This method might be a new conception and a choice to treat tubal pregnancy through artery.

Purpose:Analysing the imaging performance of solitary plasmacytoma of spine,to raise the awareness and the diagnosis accuracy.Materials and Methods: Five cases of spinal solitary plasmacytoma confirmed by clinical pathology were retrospectively analysed,to sum up the imaging performance characteristics.Results: All lesions were single vertebra involved,3 cases in thoracic and 2 cases in lumbar,3 cases occurred vertebral compression fracture.X-ray and CT showed osteolytic destruction,expansive growth and soft tissue mass,MRI showed diversity of signals,and remarkable enhancement after contrast injection.Conclusions: X-ray presents lower diagnostic sensitivity,but contributes to exclude multiple myeloma.CT and MRI can depict the morphological features and extent of tumor regions definitely,CT shows better than MRI on the thickening trabecula and residual bone in the tumor,MRI can provide a lot of information for plasmacytoma,including the diagnosis,identification and staging,which is considered as the best imaging diagnostic methods of plasmacytoma.
