Objective To study the relationship of abnormal family history in the first degree relatives and the clinical phenotype of patients with polyeystic ovary syndrome(PCOS).Methods Clinical data of first degree relatives of 139 women with PCOS were collected by questionnaires,including body mass index(BMI),waist hip ratio(WHR),and hursutism score.Follicle stimulating hormone(FSH), luteinizing hormone(LH),prolactin(PRL),testosterone(T),androstenedione(A),oral glucose tolerance test(OGTT)and insulin releasing test were measured.Results(1)Compared with patients with a negative family history of diabetes mellitus,for women with a positive family history,WHR(0.99?0.10 vs 0.79?0.08)and score of hirsutism(1.9?1.2 vs 1.8?1.2)were increased,the duration of menstruation was longer[(108?10)vs(92?19)days];A[(11?6)vs(8?5)nmol/L],homeostasis model assessment of insulin resistance(HOMA-IR,3.5?2.0 vs 2.7?1.6),area under curve(AUC) glucose[(836?245)vs(748?139)nmol?L~(-1)?min~(-1)],AUC insulin[(9670?4582)vs(7330?4311) mIU?L~(-1)?min~(-1)],fasting glucose[(5.0?1.1)vs(4.8?0.5)mmol/L]and fasting insulin[(15?8)vs (11?8)mIU/L]were increased,while early insulin secretion function index(?I60/?G60,32?22 vs 52?30),insulin sensitive index(ISI,0.019?0.011 vs 0.033?0.014)and disposition index(DI,18? 10 vs 30?22;P

Objective To evaluate the application of time to positivity (TTP)in differential diagnosis of intracranial infection caused by coagulase-negative Staphylococcus (CNS).Methods One hundred and twenty-four adult patients with positive CNS isolated from cerebrospinal fluid (CSF)including 70 cases with intracranial infection and 54 cases of CSF contamination,who were admitted in Xiangya Hospital of Central South University during January to December 201 5,were retrospectively analyzed.The difference of TTP between two groups was compared,receiver operating characteristic (ROC)curve was analyzed and the area under the ROC curve (AUC)was calculated.The application of TTP in differential diagnosis of CNS infection was evaluated.SPSS 1 8.0 software was used to analyze the data.Results TTP in intracranial infection group was shorter than that in CSF contamination group [(23.5 ±7.5 )h vs. (37.6 ±1 0.5)h,t =-8.71 7,P =0.000].The AUC of TTP was 0.854.Taking the cut-off value of 27.94 h,the sensitivity,specificity,positive and negative predictive values in differentiation of two groups were 72.7%,91 .4%,90.0% and 72.2%,respectively.There were statistically differences in TTP of Staphylococcus epidermidis,Staphylococcus haemolyticus and Staphylococcus capitis between two groups (Z =-4.496,-2.322 and -2.399,respectively,P <0.05 or <0.01 ).Conclusion TTP can be used to discriminate early intracranial infection and CSF contamination caused by CNS,and also can identify intracranial infection caused by different categories of CNS.

The discovery of microRNAs (miRNAs) has introduced a new paradigm into gene regulatory systems. Since inception, computational methods have been an invaluable tool complementing experimental approaches, and many discoveries have been obtained through combination of experimental and computational approaches. The knowledge that has been accumulated about the principles of miRNAs and target recognition were reviewed. The currently available computational methodologies and software for prediction of miRNA and their target genes also have been discussed.

Objective To report the clinical and neuroimaging features in three cases of neurosyphilis with mesiotemporal lobe lesions; and to discuss possible pathogenesis and differential diagnosis.Methods The clinical manifestations,laboratory examinations,neuroimaging features,differential diagnosis and curative effect of 3 cases of neurosyphilis with mesiotemporal lobe lesions were analyzed retrospectively.The possible pathogenesis was discussed.Results All of 3 cases had positive and high titer index of syphilis in both serum and cerebrospinal fluid.The onset symptom was abnormal cognitive functions with acute aggravation or rapid progression.Cerebrospinal fluid analysis implied lymphocyte predominant inflammatory reaction with increased protein.Electroencephalography showed localized slow waves as to the lesions.On brain magnetic resonance imaging,unilateral or asymmetrical bilateral mesiotemporal lobe was affected with long T2 signal.Herpes simplex virus encephalitis and paraneoplastic limbic encephalitis should beconsidered in differential diagnosis.The symptoms and laboratory indexes improved significantly after anti-syphilis treatment.Conclusions Neurosyphilis should be evaluatedin a patient with onset of abnormal cognitive functions and having mesiotemporal lobe lesions on magnetic resonance imaging.Promptly diagnosis and early treatment could achieve good prognosis.

Objective To compare the serum levels of transforming growth factor (TGF)-beta 1,bone morphogenetic protein (BMP)-4 in patients with rheumatoid arthritis (RA) and RA with interstitial lung disease (RA-ILD).Methods Twenty-eight RA-ILD patients,32 patients with RA but without ILD and 20 normal controls were enrolled.The RA-ILD group was further divided into early group and late group.All the observed subjects were analyzed using enzyme linked immunosorbent assay (ELISA) for the determination of serum TGF-β1 and BMP-4 levels.The relationship between the serum levels of TGF-β1,BMP-4 and laboratory examinations were investigated.Comparisions between groups were tested by one-way ANOVA analysis and ttest.Correlation of indexs were observed by Spearman method.Results Patients in the RA-ILD group were older than RA group in disease onset age,in addition,patients with ILD had better joint function and higher serum rheumatoid factor titers.The occurrence time of interstitial lung disease was 2-6 years after the onset of arthritis,with an average time of (3.0±1.2) years.The TGF-β1 levels in the RA-ILD group were slightly higher,but not statistically significant than other groups (P＞0.05).The TGF-β1 serum levels in the early RA-ILD patients were significantly increased than those of the late RA-ILD group and the RA group.BMP-4 levels in patients with RA-ILD group were less than RA without ILD group and healthy control group,and the difference was statistically significant (P＜0.05).BMP-4 level in early RA-ILD group was significantly decreased than those of the late RA-ILD group and RA group.No correlation between the serum BMP-4,TGF-β1 level (P＞0.05) no assay result correlated with laboratory parameters including ESR,CRP,RF and anti-CCP antibodies (P＞0.05).Conclusion TGF-β1 serum levels are increased and BMP-4 levels are decreased in early RA-ILD patients.The serum levels of TGF-β1 and BMP-4 may be indicatior for asymptomatic ILD and reflect disease progression.

?AlM: To analyze and study the changes of intraocular pressure ( lOP) , visual field and P-ERG on patients with big cup/disk (C/D) in 24h.
?METHODS: A total of 120 cases ( 240 eyes ) diagnosed with big C/D (C/D>0. 3) were divided into group A (C/D<0. 6, 67 cases, 114 eyes ) and group B ( C/D≥0. 6, 73 cases, 126 eyes). Forty cases (80 eyes) with small C/D (C/D≤0. 3) were chosen as control group. All cases underwent 24h lOP examination, vision examination of 30-2 SlTA - standard static threshold and pattern electroretinogram ( P-ERG) examination. The differences between the examination indexes of the three groups were analyzed.
?RESULTS:There was no significant statistical difference in the 24h average lOP (P>0. 05) among the three groups, while the amplitudes had significant statistical differences (P<0. 05). Compared with the control group, the lOP amplitudes of group B were obviously higher, and the difference was of statistical significance (P<0. 05). ln terms of static threshold visual fields, the mean deviations (MD) and pattern standard deviations (PSD) of the three groups had significant statistical differences ( P < 0. 05 ). Comparison between every two groups:compared with the control group, the MD and the PSD were significantly increased in group B, and the difference was of statistical significance (P<0. 05); while there was no significant statistical difference in group A (P>0. 05);Compared with group A, the MD and the PSD were significantly higher in group B, and the difference was of statistical significance (P<0. 05). ln terms of P-ERG examination, there was no significant statistical difference in P50’s latent periods among the three groups (P>0. 05), but there were significant statistical differences in amplitudes (P<0. 05). Comparison between every two groups: compared with the control group, the P50’s amplitude was significantly decreased in group B, and the difference was of statistical significance (P<0. 05), while there was no significant statistical difference in group A (P>0. 05); Compared with group A, the P50’s amplitude of group B was significantly lower, and the difference was of statistical significance (P<0. 05).
?CONCLUSlON: When the patients’ C/D is no less than 0. 6, there are obvious changes of 24h lOP, static threshold visual field and P-ERG’s P50 wave. For patients with big C/D, a single lOP examination is far from sufficient, so an in-depth visual function examination should be performed. Meanwhile, it’s feasible to regard C/D 0. 6 as a screening criterion for suspected glaucoma.

Objective To observe the normal structures of arteria circumflexa femoris lateralis (ACFL) and to establish digitized visible models of anterolateral thigh(ALT) flap,which can be used in clinical training and operation design.Methods The cross-sectional images from the VCH Male 3 dataset were reviewed to study ACFL structures on a section-by-section basis.Next,one adult fresh cadaver specimen was perfused with lead ox- ide-gelatine mixture to be subject to radiographic CT scanning on its lower limbs.Likewise,the cross-sectional images from the CT images were reviewed to study ACFL structures on a section-by-section basis.Three-dimensional computerized reconstructions of ACFL structures and their adjacent struetures were conducted from the two sets of data using Amira 3.1 (TGS) software respectively.Results The three-dimensional reconstructed visible models established by the above two methods perfectly displayed the anatomic relationships of ACFL structures and their adjacent structures.Conclusions Since the digitized images of ACFL structures can offer section by section in- sights into the ACFL anatomy,their 3D reconstructive models ean be applied in clinical training,pre-operative designing and virtual operation procedures.
