OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.

[Absract] Objective To investigate the imaging features of CT and MRI of echinococcosis, and improve the imaging knowledge of the disease. Methods Clinical and radiological findings of echinococcosis of ribs were retrospectively analyzed by reviewing the seventeen cases confirmed by clinical and pathological findings. All patients had CT scan, eight had X?ray plain film and five had MR examination, while 4 patients underwent additional contrast?enhanced CT examination. Results All lesions were unilateral. There were 33 ribs involved, and single involved rib was seen in 7 cases. On CT scans, 10 cases showed cystic, swelling and osteolytic bone destruction, and 7 cases showed moth?eaten osteolytic bone destruction. There were 13 cases of hydatid cyst, 3 cases of a single sac watery density shadow and 10 cases of polycystic separating wheels form. There were 4 cases of fractured ribs, 2 cases of the longitudinal fracture and 2 cases of the transverse fracture. On MRI, there was one case of rib medullary cavity expansion destruction. It was a single cyst with hypointensity on T1WI, hyperintensity on T2WI and hyperintensity on short time inversion recovery (STIR) images. There were one case of rib medullary cavity expansion destruction and 3 cases of hydatid erosion ribs cortex among 4 cases of polycystic type. Polycystic type echinococcosis appeared hypointensity on T1WI, hyperintensity on T2WI and hyperintensity on STIR images. Polycystic type had mother sac and ascus structure, and signal intensity of ascus was higher. STIR sequence showed more clearly polycystic structure. Conclusions CT and MRI can clearly show location of echinococcosis of ribs. There are the imaging features of cystic, swelling and osteolytic bone destruction or complicating cyst of polycystic type which can help the qualitative diagnosis of rib echinococcosis.

Objective To investigate the source of the blood flow through ventricular septum in normal subject caused by slice-thickness artifact in echocardiography. Methods Echocardiography was performed in 50 normal subjects without ventricular septum defect by two models of echocardiography unit equipped with two models of transducer, observing the conditions and sections in which the blood flow through ventricular septum could be detected. Results The blood flow through ventricular septum was detected in 8 normal subjects using the certain model of echocardiography unit,especially in parasternal four chambers section and parasternal irregular sections, while the blood flow through ventricular septum wasn't detected in the other 42 subjects by any echocardiography unit. The blood flow through ventricular septum was caused by coronary vessel in atrioventrieular groove proved by combining dynamic observation with anatomy analysis. Conclusions The blood flow through ventricular septum in normal subjects, a kind of slice-thickness artifact in echocardiography,is caused by coronary vessel in atrioventricular groove mapped into intact ventricular septum.

OBJECTIVETo investigate the protective effect and action mechanism of petroleum ether extracts from Saussurea involucrate on brain tissues of hypoxia rats under constant pressure and closed conditions.

METHODThe PESI dosage-dependent experiment for hypoxia rats was conducted under constant pressure and closed conditions by intraperitoneally injecting 125, 250, 500 mg x kg(-1) to finalize that the optimum dosage is the high dose of PESI. Afterwards, 90 Wistar rats were randomly divided into the hypoxic model group, the acetazolamide 250 mg x kg(-1) group and the PESI high dose group. Each group was further divided into three subgroups according to different hypoxia times, with 10 rats in each subgroup. Under the same hypoxia and administration conditions, the rats were sacrificed after 0, 3, 6 h respectively. Their brain samples were collected for common pathological observation and immunohistochemical staining of HIF-1alpha. Real-time RT-PCR was used to detect HIF-1alpha, EPO, HO-1 and Caspase-3 gene expressions. And the Western blot assay was adopted to detect HIF-1alpha protein expression.

RESULTThe brain tissues of the hypoxia model group were severely damaged with the increase in the hypoxia time. The acetazolamide group and the PESI high does group were damaged in a much lower degree. According to the gene expression and the Western blot assay, high dose of PESI could inhibit HIF-1alpha expression. According to the pure gene expression test, high dose of PESI could increase EPO and HO-1 mRNA expressions, but inhibit Caspase-3 mRNA expression.

CONCLUSIONPESI's protective mechanism for brain tissues of hypoxia rats under constant pressure and closed conditions may be related to its effects in inhibiting HIF-1alpha expression, increasing EPO expression and resisting cell apoptosis.

BackgroundChoriodal neovascularization is an important ocular manifestation of angiogenesis in eyes,which derives from the choroid capillaries.Recent studies have found that complement activation is playing a key role in the laser-induced CNV.Because of the key position of CFB in the alternative pathway,bytargeting CFB and blocking the alternative pathway may provide an approach to observe the role of this alternative pathway in the generation of CNV.Objective This study was to investigate the inhibitory effect of reconstructed complement factor B (CFB)-small interfering ribonucleicacid(siRNA)on choroidal neovascularization (CNV)and its mechanism. Methods Experimental CNV was induced by laser photocoagulation in 96 eyes of 48 clean Brown Norway rats.The rats were randomly divided into 4 groups.25,50 and 75 μg B factor siRNA were injected via caudal vein on 1 day,3,5 days after photocoagulation in different dose groups,and normal saline solution was injected at the same way in experimental control group.Other 12 normal rats were used as blank control group.Fundus fluorescein angiography(FFA) was performed on 3,7,14,21,28 days after injection of CFB-siRNA and CNV was scored.The expressions of vascular endothelial growth factor(VEGF) and factor Ⅷ in choroid were detected by immunochemistry.The expressions of CFB-siRNA,VEGF,transforming growth factor β2( TGF-β2 )proteins in choroid were determined using immunochemistry in 7,14,21,28 days,and the expressions of mRNA of CFB-siRNA,VEGF,TGF-β2 were examined by reverse transcription polymerase chain reaction(RT-PCR). ResultsFFA revealed that the CNV rates in various doses of CFB-siRNA groups were significant lower than those of experimental control group in various time points(P＜0.05),and those in 75 μg B factor siRNA were decreased in comparison with 25 μg B factor siRNA (P＜0.05).Immunochemistry showed that the intensities of the VEGF and factor Ⅶ expression in various doses of CFB-siRNA groups were weaker than the blank control group ( P ＜ 0.05 ).Compared with the control group,the expression of CFB reduced in 7 days,and then approached to the level near the control group.Fourteen to twenty-one days after injection of CFB-siRNA,VEGF and TGF-β2 depressions in different doses of CFB-siRNA groups were lower than blank control group( P＜0.05 ).CFB expression in choroid showed the lower levels in CFB-siRNA injection group compared with blank control group in from 7 through 21 days (P＜0.05).RT-PCR displayed the gradual increase of CFB mRNA and curve-like changes of VEGF and TGF-β2 with time prolong. Conclusions Recombinated CFB-siRNA can effectively inhibit laser-induced CNV by down-regulating the expression of VEGF and factor Ⅷ.Alternative pathway of complement plays an important role in the production of CNV.

OBJECTIVETo study the effect of Lugu Ganoderma Lucidum (LGL) on low-density lipoprotein (LDL) oxidation and monocyte adhesion to endothelium (AdM-E) induced by oxydative LDL and advanced glycosylation endproducts (AGE) by using serum pharmacological technique.

METHODSLDL oxidation was determined by measuring the thiobarbituric acid reactive substances in the supernatants, and AdM-E was determined by measuring myeloperoxidase activity of adherent monocyte.

RESULTSSerum derived from rats 0.5 hrs, 1 hr, 2 hrs, 3 hrs after LGL administering 0.12 g/kg once and 0.5 hrs, 1 hr after LGL administering twice showed no significant effect on LDL oxidation, but the serum from rats 2 hrs, 3 hrs after LGL 0.12 g/kg administering twice or from rats after 10 successive days LGL administering in dose of 0.12 g/kg, 0.24 g/kg and 0.72 g/kg, all could lower the LDL oxidation (P < 0.05). Besides, the serum from rats with 10 days LGL administering of all dosages also could inhibit AdM-E induced by AGE (P < 0.05), and those of 0.24 g/kg and 0.72 g/kg could inhibit AdM-E induced by oxydative LDL (P < 0.05).

CONCLUSIONLGL could decrease LDL oxidation and AdM-E induced by AGE or oxydative LDL.

OBJECTIVETo retrospectively analyze the effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on childhood chronic myelogenous leukemia (CML).

METHODOf the 24 consecutive cases, 16 were boys and 8 were girls. The median age of patients was 12 (3 - 16) years old; 16 cases were in chronic phase (CP) of CML, 1 case in accelerated phase (AP) and 5 cases in blastic phase (BP). Allo-HSCT from HLA identical siblings were performed for 5 cases, HLA haplotype was performed for 14 cases and unrelated allo-HSCT for 5 cases. Twenty-four cases underwent allo-HSCT with conditioning regimen of BUCY. Prophylaxis of graft versus host disease (GVHD) included CsA + MTX plus MMF. The average follow-up was 36 months.

RESULTAll of patients were successfully engrafted. The 5-year overall survival (OS) of the 24 cases was 81%. Four patients died after allo-HSCT including 3 cases in BP from haploidentical donors and 1 case in CP from HLA identical sibling. The 5 cases who received unrelated allo-HSCT have been alive. Among the 10 cases who survived over 5 years, 3 had chronic GVHD.

CONCLUSIONChildren with CML could be treated effectively with allo-HSCT. There were no significant differences among different donors. Transplantation to children with CML should be performed as early as possible. Preparative regimen adjustment before transplantation, the transplantation of associated comorbidities and effective prevention and treatment for CML patients after prolonged graft survival of high quality have important significance.

OBJECTIVETo analyze the therapy of hypertensive outpatients among different grade hospitals in Beijing.

METHODSThirty-nine hospitals including 4 third grade hospitals, 4 second grade hospitals and 31 first grade hospitals in Beijing were selected randomly (by stratified randomization). The grade was accredited according to the hospital accreditation standard issued by Ministry of Health of the People's Republic of China.

RESULTSThe average hypertension control rate (< 140/90 mm Hg, 1 mm Hg = 0.133 kPa) in outpatients was 32.3%. The hypertension control rate in the third grade, second grade, first grade hospitals were 37.7%, 36.9%, and 31.2% respectively. There was no difference in the control rate among the three different grade hospitals (P > 0.05). The frequency to use anti-hypertension drugs including long-acting calcium antagonism, ACEI, beta-receptor blocker in the third grade hospitals was significantly higher than those of the first and second grade hospitals. The rate of examination using ultrasonic cardiogram, CT, Holter and ambulatory blood pressure monitoring were significantly higher in the third grade hospitals than that of the first and second grade hospitals. There were significant differences in annual cost of hypertension treatment among three different grade hospitals (P < 0.01), being the highest (1567.5 yuan) in the third grade hospitals, medium (845.4 yuan) in the second grade hospitals, the lowest (651.8 yuan) in the first grade hospitals.

CONCLUSIONSSignificant difference in the cost of hypertensive treatment among three different grade hospitals exists in Beijing. However, there was no difference in the control rate among them. The overall hypertension control rate is 32.3%, leaving 67.7% uncontrolled. Efforts to increase the hypertension control rate should be made in all hospitals. How to guide and arrange the hypertension patients to consult a suitable hospital is important for rational and economical use of health cost.

OBJECTIVETo investigate the clinical, pathological and immunohistochemical features of vulvar intraepithelial neoplasia (VIN).

METHODSAccording to the 2004 modified terminology of International Society for the Study of Vulvovaginal Diseases (ISSVD), the cases were diagnosed as VIN from patients who had performed vulvar biopsy in Beijing Wuzhou Women's Hospital from February 2009 to December 2011, which were reclassified as usual VIN and differentiated VIN. The clinical and pathological studies were conducted respectively. MaxVision immunohistochemical staining was used to detect the expression of Ki-67, p16 and p53 proteins.

RESULTSThere were 20 cases of VIN in 237 patients, and the incidence of VIN was 8.4% in all of contemporary vulvar biopsy. In 17 cases of usual VIN, mean age was 29.6 years, the lesion typically presented with atypical cells involving almost all layers of the epithelium, which was equivalent to the high-grade squamous intraepithelial neoplasia of cervix. Immunohistochemistry for Ki-67 and p16 was strongly positive in usual VIN. High risk human papillomavirus (HPV) detection was also positive. The incidence of differentiated VIN was less than usual VIN, and there were only 3 cases in this study. In differentiated VIN, patients aged over 50 years, with mean of 53.7 years, and the lesion most commonly presented with lichen sclerosis background. There were epithelial thickening and extending, and parakeratosis, and atypia was strictly confined to the basal and parabasal layers of the epithelium where the cells enlarged with abundant eosinophilic cytoplasm, presented with prominent nucleoli, increased cellularity and abnormal keratinization. In differentiated VIN, p53 was strongly positive, Ki-67 and p16 immunohistochemical expression was confined to the basal layer only.

CONCLUSIONSVIN is a precursor of invasive squamous cell carcinoma of the vulva. The modified terminology of ISSVD classifies VIN as high-grade lesions. Definitive pathological diagnosis of VIN plays an important role in its timely treatment and the prevention of vulvar carcinoma.
