Objective To investigate the pathological and immunohistochemical characteristics of female bladder ectopic skene glands.Methods A female with bladder tumor was treated in our hospital in May 2013.Preoperative so(n)graphy revealed a 0.9 cm×0.6 cm round solid mass in the bottom of bladder wall.Mass was hypoechoic homogeneous with regular shape,blood flow within the mass was noted.The tumor was treated with transurethral resection.Routine pathological examination suggested bladder ectopic Skene glands.Immunohistochemical stains for prostate specific antigen (PSA),prostate spectific acid phosphatase (PSAP),androgen receptor (AR),estrogen receptor (ER),CD10,cytokeratin 14 (CK14),cytokeratin 18 (CK18),P63,high molecular weight cytokeratin (34βE12),α-methylacyl-CoA racemase (AMACR/p504s) were further performed.Results Routine pathological examination showed prostate glands composed of prostate gland epithelial cells and basal cells in a submucosal location.Immunohistochemical stains showed:PSA-,PSAP +,AR +,ER-,CD10+,CK18 +,CK14-,P63 +,34βE12 +,AMACR-.Conclusions Routine pathological examination combined with immunohistochemical stains such as PSA,PSAP,and others,can be used to diagnose ectopic Skene glands disease.Female bladder ectopic Skene glands is a benign lesion,and the prognosis is good.

Objective To evaluate the role of early cleavage embryo in combination with embryo growth rate and morphology scoring in embryo selection in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods Six hundred and ten IVF/ICSI cycles were randomly assigned to group A(269 cycles) and group B(341 cycles). In group A, transferred embryos were chosen according to embryo growth rate and morphology scoring by 72 h(D3) after fertilization, while early cleavage embryo was added to the selecting system in group B. The pregnancy rate and implantation rate were compared between two groups, and the clinic outcomes were compared between transfers with early cleavage embryos and without early cleavage embryos in group B. Results The pregnancy rate and implantation rate in group B were significantly higher than those in group A (P < 0.05). Transfers with early cleavage embryos also achieved much higher pregnancy rate and implantation rate in group B (P < 0.01). Conclusion Compared with embryo growth rate and morphology scoring, early cleavage embryo in combination with embryo growth rate and morphology scoring can improve the clinical outcomes in IVF/ICSI cycles.

AIM: To understand the relation between the penetrating keratoplasty rejection and the methods of cornea preservation.
METHODS: The 30 Wistar rats as donator and 60 SD rats as receptor were used to establish the animal models of penetrating keratoplasty rejection. And 60 SD rats were randomly divided into 3 groups. Donor cornea of Wistar rats preserved in different methods were used separately in 3 groups. The penetrating keratoplasty rejection index ( RI ) , means survival time ( MST ) of corneal grafts and pathological changes in post -operation were analyzed.
RESULTS: The MST was ( 10. 4±1. 70 ) d in moist-chamber- preserved group (Ⅰ), ( 12. 9 ± 1. 81 ) d in medium-term-preserved group (II) and (16. 1±2. 57) d in cryopreserved group ( Ⅲ) . The MST in the cryopreserved group was evidently prolonged, showing a significant correlation compared with other two groups (P<0. 01). The sections with HE staining revealed that the severity of inflammation in Ⅲ group was reduced compared with that of Ⅰ, II group after 10d of keratoplasty.
CONCLUSION: The postoperative rejection of penetrating keratoplasty in rats is decreased and rejection time is delayed in cryopreserved cornea.

Objective To observe the dynamic changes of bone density and bone strength after alveolar ridge augmentation with Titanium Nickel shake memory alloy (TiNi-SMA) distractor and acellular dermal matrix (ADM).Methods Twelve adult healthy male dogs were selected.After the animal model of alveolar atrophy was set up,on one side of mandible,two S-shaped distractors were placed.The diameter of S-shaped distractor was 1 mm and the rebound temperature was 33℃.The ADM was placed on the distraction gap and fixed by the feet of distractors.The other side was placed only with distractors,serving as control side.Six dogs' mandibles were harvested after 1 and 3 months respectively.Dual energy X-ray absorptimetry (DEXA) was used to scan bone density around the distraction gap.Mechanical machine was used to test compression strength and elastic modulus.Results Months after distraction,the bone density of upper distraction gap ,distraction gap and low distraction gap were respectively (0.714±0.238) g/cm2,(0.512±0.435) g/cm2 and (0.615±0.043) g/cm2 on experimental side.The compression strength and elastic modulus were (36.54±7.32) Mpa and (1674.10±256.43) Mpa.All of above were higher than those of control side.Conclusions ADM can improve the bone quality, increase bone density and intensity and is an ideal guided bone regeneration (GBR) membrane for alveolar ridge agumentation with TiNi-SMA distraetor.

Objective To explore effects of three different health education ways to improving perimenopausal women syndrome in community. Methods A total of 90 women were divided into three groups received different health education style respectively: community health education manual ( HEM) , health education manual + lectures ( HEML) , health education manual + lectures + exercise instruction ( HEMLE), athletic time and Kupperman index change were evaluated. Results The athletic time increased more in HEML group than that in other two groups; Kupperman index change decreased more markedly in HEML and HEMLE groups than that in HEM. Conclusions The methods of HEML and HEMLE are better to improve perimenopausal syndrome than HEM.

Objective To investigate the relationship and clinical significance of blood plasma brain natriuretic peptide (BNP) and Keshan Disease (KD). Methods Seventy KD patients and 30 healthy volunteers in endemic area were investigated with Doppler Echocardiography for the measurement of left ventricular end-diastolic diameter(LVEDD) and left ventricular ejection fraction (LVEF), and the plasma BNP levels were determined with microparticle enzyme immunoassay. Results The BNP levels in plasma in KD patients [(444.61±102.31), (87.21±23.15)ng/L] were significantly higher than that of healthy volunteers [(34.91±15.21)ng/L],the differencesbeing statistical significant (q=39.74,5.82,P<0.01). The BNP levels in chronic KD patients were higher than that of latent KD patients (q=37.62,P<0.01). The plasma BNP levels in KD patients with LVEDD 60 nun [(928.80±134.27)ng/L] were significantly higher than those of patients with LVEDD 55～60 mm [(89.24±52.31)ng/L] and LVEDD<55 nun [(67.14±6.92)ng/L],the differencesbeing statistical significant (q=44.30,48.16, P<0.01), The plasma BNP levels in KD patients with LVEF<35%[(1654.21±421.35) ng/L] were significantly higher than those of patients with 35% ~ 50%[(421.54±112.32)ng/L] and50% [ (81.21±72.85 ng/L)], the differencesbeing statistical significant(q=24.91,72.66, P<0.01), The BNP levels in LVEF 35%～50% were higher than that of 50% (q=11.84,P<0.01). Conclusion The plasma BNP levels were important for the diagnosis, grouping, therapeutic effect and prognostic evaluation of KD.

Objective To assess the diagnostic value of anti-cyclic citrullinated peptide antibody(an- ti-CCP),rheumatoid factor,anti-perinuclear factor(APF)and anti-keratin antibody(AKA)for juvenile rheumatoid arthritis(JRA)and compare it with rheumatoid arthritis(RA).Methods Anti-CCP was determined by ELISA in 54 serum samples of JRA patients,31 from patients with other rheumatic diseases and 116 RA patients.RF was determined in the same samples by latex agglutination test.APF and AKA were determined by indirect immunofluorescent assay.Results The sensitivity of anti-CCP,RF,APF and AKA was 61.1%, 57.4%,37.0% and 18.5% and their specificity was 96.8%,93.6%,96.8% and 100%,respectively for the diag- nosis of JRA.The sensitivity of anti-CCP resembleed that of RF,Anti-CCP was more sensitivity than APF and AKA in JRA.The sensitivity of anti-CCP,RF,APF and AKA was 82.3%,78.3%,48.7% and 25.4% and their specificity was 95.7%,73.7%,91.6%,94.0% respectively,for the diagnosis of RA.Anti-CCP,RF,APF and AKA were less sensitive in JRA than in RA.There was no statistical significance in specificity of these anti- bodies for the diagnosis of JRA and RA.Conclusion The detection of anti-CCP,RF,APF and AKA are use- ful for the diagnosis of JRA,but are less sensitive than in adults RA.

Objective To investigate the management and control of hypertension in patients with chronic kidney disease(CKD) and its associated factors.Methods Data of 726in-patients with CKD and hypertension who hospitalized in our hospital from March 2009 to April 2010 were studied.Results 91.74％ of patients was treated with antihypertensive medications,and 21.21％, 22.59％, 19.56％, 28.37％ of patients received 1, 2, 3, ≥4 antihypertensive drugs,respectively.42.4％ of patients with CKD and hypertension could be controlled up to the standard,and the mean blood pressure was(137.86±20.75)/(76.30±11.35) mm Hg.There was significant difference among stage 1 plus 2, 3, 4 plus 5 (non-dialysis), 5 (dialysis) kidney diseases, with the hypertension control rate being 50.8％, 46.7％, 42.0％, 33.5％, respectively.The hypertension control rate of non-dialysis patients was significantly higher than that of dialysis (44.9％ vs 33.5％,P＜0.05).There was no significant difference between blood dialysis group and peritoneal dialysis group(32.3％ vs 38.7％, P＞0.05).Multivariate Logistic regression analysis showed that female (OR=1.787, 95％CI 1.045-3.056)and ACEI application (OR=4.378, 95％CI1.830-10.472) were positively associated with hypertension control.Whereas, diabetes (OR=0.415, 95％CI 0.188-0.919)and pulse pressure (OR =0.847, 95％ CI 0.811-0.885) were associated with inadequate blood pressure control.ConclusionsDespite almost universal hypertension treatment is used in patients with CKD and high blood pressure, the hypertension control rate is still suboptimal.Female and ACEI are positively associated with adequate hypertension control, whereas diabetes and pulse pressure are negatively associated with the standard.

OBJECTIVETo investigate the effects of alpha-linolenic acid (ALA) on inflammation and oxidative stress in the diabetic rats.

METHODSAn experimental type 2 diabetes mellitus model was induced by feeding male SD rats with diet of high fat for 4 weeks and then injected them intraperitoneally with streptozocin (STZ) at 30 mg/kg. Then the animals were randomly divided into three groups (n = 10): control group, diabetic group and ALA group. Four weeks later, tumor necrosis factor (TNF)-a, soluble P-selectin (sP-selectin), soluble intercellular adhesion molecule-1 (sICAM-1), nitric oxide (NO) production, malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in the serum were determined.

RESULTSInflammatory agents including TNF-alpha, sP-selectin and sICAM-1 increased in diabetic rats to compare with control group. Treatment with ALA significantly decreased TNF-alpha, sP-selectin and slCAM-1 to compare with diabetic group. Furthermore, compared with control group, serum MDA production increased whereas NO production, SOD and CAT activities decreased in diabetic rats. Treatment with ALA reduced MDA production, increased NO production, promoted SOD and CAT activities compared with diabetic group.

CONCLUSIONThese results indicate that diet rich in ALA exerted the anti-inflammatory and anti-oxidative effects in diabetic rats, which may be beneficial to the prevention and treatment of diabetes.
