Objective To observe the relation between content of type Ⅲ collagen and expression of decorin in paraurethral connective tissue in patients with stress urinary incontinence(SUI). Methods Transvaginal biopsies were obtained from the paraurethral connective tissue in 43 SUI and non-SUI control women. The concentration of type Ⅲ collagen was determined by immunohistochemical technique, electrophoretic separation and quantification. RT-PCR was used to verify the mRNA level of decorin. Results The mean concentration of type Ⅲ collagen was significantly reduced in patients with SUI(23?4), compared to the control group(34?6, P

Objective To investigate the prevalence of lower urinary tract symptoms in women in a community in Fuzhou. Methods We designed a patient-completed questionnaire according to Bristol Female Lower Urinary Tract Symptoms (BFLUTS) questionnaire.A few parts of the questionnaire were adjusted based on living habits and social backgrounds in our country.The health care workers distributed and collected the questionnaires and instructed the women to fill in them one by one. Results A total of 6066 questionnaires were distributed and 5587 were collected. Of the responders 4745 women were more than 18 years. The prevalence of stress incontinence, urgency incontinence,urgency,frequency and nocturia were 9.0% (425/4745),2.4% (113/4745),10.3% (489/4745),1.5% (72/4745) and 9.8% (446/4745),respectively.The prevalence of storage symptoms increased with age,showing a 20.5%(104/507) in 18~27 years’ group,19.1% (332/1740) in 28~37,22.5%(338/1503) in 38~47,32.2%(202/628) in 48~57,41.2%(61/148) in 58~64,58.0% (127/219) in ≥65 years’ group. The overall prevalence was 24.5%.The prevalence of delayed urinary,intermittent stream,increased abdominal urination, incomplete emptying and voiding pain were 7.0%(330 cases),4.1%(194),4.6% (217),4.9% (233) and 4.8%(229),respectively.The prevalence of general voiding dysfunction increased with age,showing a 13.0% (66/507) in 18~27 years’ group,9.3% (162/1740) in 28~37,10.7%(161/1503) in 38~47,13.2%(83/628) in 48~57,16.2% (24/148) in 58~64 and 26.9%(59/219) in ≥65 years’ group.The overall prevalence was 11.7%. Conclusions The prevalence of lower urinary tract symptoms are high in community-dwelling women,and the prevalence of storage symptoms are more common than that of voiding dysfunction in these women.

[Objective]To evaluate the surgical techniques,rehabilitation and the results of internal fixation performed for ankle joint fracture.[Method]One hundred and twenty-six patients with ankle joint fractures were treated with open reduction and internal fracture. According to the Danis-Weber classification,there were 12 cases of type A, 86 cases of type B, 28 cases of type C.The follow-up interview period varied from one year to five years,with an average of eighteen months.[Result]The number of patients whose results was better, good, fair and poor was 65, 44, 11 and 6.The total percent-age of good to better clinical results was 86.51%.[Conclusion]Operative treatment and rehabilitation may provide satisfactory fracture reduction and clinical results for ankle joint fracture.The opportunity selection,correct fracture pattern estimation, proper internal fixation and rehabilitation are important to achieve better long term results.

[Objective]To investigate the clinical use of spiral CT with 3D Reconstruction for fractures of the tri-ankle joint.[Method]Fifty-six cases of tri-ankle joint fractures treated in our hospital from 1999 to 2004 were studied respectively.The ankle joint X-ray and spiral CT with 3D reconstruction were taken for all the cases preoperatively.The results were analyzed and compared with finding in operation .Scanning parameters of spiral CT were: 2 to 5mm collimation,3 to 5mm table speed and 1.5 to 3mm reconstruction interval.[Result]Fractures were demonstrated definitely by spiral CT in all the cases.Analyses of the results showed the superiority of spiral CT with 3D reconstruction in the fracture classification.Exact assessment of fragments and total agreement of the preoperative results were compared with findings in operation.[Conclusion]Operative treatment and rehabilitation may provide satisfactory fracture reduction and clinical results for ankle joint fracture.Well-timed treatment,correct fracture pattern estimation,proper internal fixation and rehabilitation are important to achieve better long term results.

Traditional sequences of magnetic resonance imaging (MRI) such as T1-weighed imaging, T2-weighed imaging, and fluid-attenuated inversion recovery (FLAIR) imaging can sensitively detect the subacute and chronic intracranial hemorrhage; gradient echo sequence can detect various stages of intracranial hemorrhage, but there is no correlation between the signal intensity of the hematoma and the time of the presence of hematoma. Diffusion-weighted imaging and apparent diffusion coefficient may provide more information about the center and surrounding areas of hematoma, as well as the hemorrhagic tendency after infarction.

[Objective] In order to explore the optimal minor-factor culture system of CIK/NK cells by proliferating CIK/NK cells using single-factor,bi-factor,and tri-factor combinations of IL-2,IL-7,and IL-12.[Methods] Ficoll-Hypaque method was used to separate cord blood mononuclear cells and divide them into 6 groups.Add single-factor,bi-factor,and tri-factor combinations (IL-7;IL-12;IL-7 + IL-12;IL-2 + IL-7;IL-2 + IL-12;IL-2 + IL-7 + IL-12) of IL-2 (80 ng/mL),IL-7 (40 ng/mL),and IL-12 (40 ng/mL) and culture them in total 21 days then harvest the cells.To collect cell suspensions of each group in culture outset and day 21 and to count the proportion of CD3+ CD56+ CIK cells and CD3- CD56+ NK cells with flow cytometry.[Results] The proportion of CIK cells in single-factor culture system of IL-12 was the highest in all groups (30.23 ± 1.18%).The proportion of CIK cells in bi-factor culture system of IL-2 + IL-12 can raised to 18.58 ± 0.68%.The proportion of CIK cells of the two groups above can reach the level of that using traditional multi-factor culture methods.NK cell proportion in IL-12 was 30.23 ± 1.18%,NK cell proportion in IL-2 + IL-7 can also reach to 29.52 ± 0.89%.[Conclusions] It is adoptable to proliferate CIK/NK cells using minor-factor culture system of IL-12,IL-2 + IL-12,or IL-2 + IL-7.

China donation after Citizen's death (CDCD) has been organized since 2010,and now has been synchronized with the international organ transplantation.At present,liver transplantation has become the only safe and curative treatment for the end-stage liver diseases.Nevertheless,there is much restriction over further exploration of this technique.This article will mainly focus on donation after brain death (DBD),and summarize the four dominating injuries of donor liver,including the donor's primary injury,cut and perfusion injury,graft preservation injury,and ischemia-reperfusion injury.

Sustained hypoxic pulmonary vasoconstriction (HPV ) as experienced at high altitude can lead to hypoxic pulmonary hypertension(HPH).HPV,a special physiological phenomenon of lung,is the physiological reflex of organism in hypoxic envi-ronment.However,in high altitude hypoxic environment,the sustained HPV can lead to pulmonary vascular remodeling and right ventricular hypertrophy,at the same time,the degree of hypoxia in alveoli can be aggravated.Vicious circle of hypoxia is formed,further causing the severe high altitude sickness such as pulmonary edema and pulmonary heart disease.HPV appears in preliminary of HPH,but in the chronic phase,irreversible hy-poxic pulmonary vascular remodeling forms.Therefore,studying the mechanism of HPV and the effect of HPV in HPH can pro-vide targets and ideas for the prevention and treatment of high al-titude sickness. Additionally, in preliminary stage of HPV, prompt treatment is critical for the prevention of high altitude sickness.However,the mechanism of HPV and its roles in HPH are still not fully elucidated in current studies.This paper sum-marizes the studies about HPV in HPH of recent years,aiming to provide references for researchers and clinical treatment in this research field.
