Objective This study aimed to explore the clinical value of human papilloma virus ( HPV) E6/E7 mRNA tests in identifying precancerous lesions of the uterine cervix-cervical intraepithelial neoplasia 2 or more CIN2+( CINⅡand CINⅢ).Methods This study is a cross-sectional survey design , between December 2011 to December 2013.The specimens were collected from the First People′s Hospital of Huizhou and the Third People′s Hospital of Huizhou in Department of Obstetrics and Gynecology outpatient and inpatient of cervical disease suspected patients , with thin-prep cytologic test ( TCT ) and histopathological results as reference , detected 345 patients of exfoliated cervical epithelial cells by using the branched DNA (b-DNA) technology to evaluate the application value of high risk HPV E 6 /E7mRNA in the clinical diagnosis of CIN.Using spss 19.0 software for data analysis.Results (1)Compared with TCT, the positive rate of E6/E7 mRNA in 325 samples were grading by cytology as follows: no intraepithelial lesion cells (NILM) 21.1%(40/190), atypical squamous cells (ASC) 38.5%(15/39 ), low-grade squamous intraepithelial lesions ( LSIL ) 76.9% ( 30/39 ) , atypical squamous cells can not exclude high-grade intraepithelial lesions (ASC-H) (8/10), high-grade squamous intraepithelial lesions (HSIL) 72.3%(34/47), TCT grades and HPV E6/E7 mRNA positive rate showed linear association (χ2 =67.654,P<0.01;r=0.497, P<0.01 ); and with HPV E6/E7 mRNA copy number was also relevant ( r =0.511, P <0.01).(2) Compared with pathological results , the positive rate of E6/E7 mRNA in 164 women samples were grading by pathology as follows:with NILM was 27.8%(10/36), with CIN Ⅰwas 65.9%(29/44), with CINⅡwas 80.6%(54/67), and with CINⅢwas 82.4%(14/17), pathological grades and HPV E6/E7 mRNA positive rate showed a linear correlation (χ2 =26.426, P<0.01; r=0.438, P<0.01); and the number of copies correlated with the increase of pathological grades too (r=0.543, P<0.01).(3) Screening effectiveness analysis results showed , the sensitivity of HPV E6 /E7mRNA was 84.6% while TCT was 47.7%.The sensitivity and specificity were 40.0% and 91.1% respectively when HPV E6/E7 mRNA and TCT processed as sequential detection test.The CIN2 +( CINⅡand CIN Ⅲ) best diagnostic critical point of 890.26 copies/ml,was established using receiver operating characteristic ( ROC) curve.The sensitivity and specificity were 58.5% and 93.7%, respectively.Conclusions The sensitivity of HPV E6/E7 mRNA test is better than TCT, the specificity is high in HPV E6/E7 mRNA and TCT processed as sequential detection test.Using the optimal cut-off value of ROC curve to detect CIN 2+has high sensitivity and specificity, so the detection of HPV E6/E7 mRNA may have some clinical value in screening and risk assessment of precancerous lesions of the uterine cervix.

Objective To investigate the elasticity of the radial artery wall in type 2 diabetes mellitus (T2DM) patients with elastosonography. Methods A total of 37 patients with T2DM and 42 normal subjects were studied with elastosonography. The systolic diameter (Ds) and diastolic diameter (Dd) of the radial artery were measured, and the strain ratio of the blood in the radial artery to the wall of the radial artery was calculated. Results The strain ratio of the radial artery in T2DM group was significantly higher than that in normal group (P＜0.05). There was no significant difference in Ds and Dd of the radial artery between T2DM group and the control group (P＞0.05). Conclusion The early change of the radial artery wall elasticity in patients with T2DM can be assessed with elastosonography.

Objective To evaluate left atrial(LA) function in patients with prophase type 2 diabetes mellitus(T2DM) combinated with or without hypertension using left atrial volume tracking method(LAVT). Methods Thirty-one simple T2DM(T2DMI group) ,21 T2DM accompany with hypertension(T2DM2 group) and forty-five healthy subjects (control group) were enrolled in this study. Ultrasound LAVT(EUB-6500, Hitachi Medical Corporation) was applied to display and analyzed the LA volume loop imaging on the standard LV apical two and four chamber views. The maximal and the minimal LA volume (LAVmax, LAVmin) and the volume before LA contraction (LAVp) were recorded from the LA volume loop. The body surface area was used to correct these volume indexs. The LA reservoir function was assessed by calculating the total of LA filling volume (LAVItotal) and the expansion index(iLAVIe). The passive and active emptying percentage of the total emptying volume(LAVIpass, LAVIact) and the emptying index(iLAVIpass,iLAVIact) were caculated as the parameters of the LA conduit and booster pump function. Results Compared with the values in the control group, the LAVhotal,LAVIact were significantly higher and the LAVlpass,iLAVlpass were lower in the T2DM group (all P<0.05) ,while the iLAVIact was higher only seen in the T2DM2 group(P<0. 05). The LAVlact, iLAVIact were higher and the LAVIpass was lower in T2DM2 group than those in the T2DM1 group (all P<0.05). Conclusions The LA conduit hypofunction in primary in the prophase T2DM,when combinated with hypertension the LA constriction function compensatorily increased, LAVT can evaluate the function of LA in patients with T2DM accurately and rapidly.

Objective To observe the rotation of subendocardium and subepidium by two-dimensional speckle tracking imaging(2D-STI),and to evaluate its performance in diastolic heart failure patients(DHF)with a normal left ventricular ejection fraction. MethodsNinety-seven consecutive clinically stable patients were enrolled in this study [41 healthy controls,36 with diastolic heart failure,20 with systolic heart failure (SHF)]. High frame rate dynamic two-dimensional images were recorded at the left ventricular short-axis view,including basal, papillary muscle and apical planes. Subendocardial and subepicardial global rotation were measured using Q-lab 7.0 software offline. Results ① In all the subjects, the rotation of the subendocardium was obviously greater than that of subepicardium. ②As seen from the apex,left ventricular subendocardium and subepicardium performed a wringing motion with a clockwise rotation at the base and countclockwise rotation at the apex. ③In the apical plane, subendocardial rotation was significantly lower in both heart failure groups than in controls,and was depressed to a larger extent in SHF patients than in those with DHF. Subepicardial rotation was no significant difference between the DHF group and the control group, though it was significantly lower in patients with SHF. ④At the base, the rotation of subendocardium and subepicardium were not different between DHF and control groups, but it was significantly reduced in patients with SHF. Conclusions The subendocardial rotation is reduced, but subepicardial rotation is normal in DHF patients. On the other hand, in patients with SHF, subendocardial and subepicardial rotation are both reduced. The left ventricular systolic properties are impaired in DHF patients.

Objective:To observe the clinical efficacy of Xiaosheng Powder ultrasonic nebulization combined with meibomian gland massage in treating liver depression and Yin deficiency pattern of meibomian gland dysfunction dry eye.Methods:Randomized controlled trial. From March 2021 to September 2021, a total of 50 patients (100 eyes) diagnosed with meibomian gland dysfunction dry eye of the liver depression and Yin deficiency pattern at the Ophthalmology Hospital of China Academy of Chinese Medical Sciences were selected. They were randomly divided into two groups using a random number table, with 25 patients (50 eyes) in each group. The control group received 0.1% sodium hyaluronate eye drops combined with meibomian gland massage, while the treatment group received Xiaosheng Powder nebulization combined with meibomian gland massage. Both groups were treated for 4 weeks.

Objective To investigate the expression of peripheral programmed death (PD)-1hiCXCR5-CD4+T cells and its clinical significance in systemic lupus erythematosus (SLE). Methods Peripheral blood PD-1hiCXCR5-CD4+ T cells from 21 SLE patients and 16 healthy controls were examined by flow cytometry. The levels of serum anti-double-stranded deoxyribonucleic acid (dsDNA) antibodies were determined using immunoradiometric as-say. Data were analyzed with t test and Pearson's correlation test. Results The per-centages of PD-1hiCXCR5- cells within CD4+ T cell were significantly higher in SLE patients [(2.1 ±2.0)％] compared to normal controls [(0.3±0.3)％] (t=2.959, P<0.01). The percentages of PD-1hiCXCR5-cells within CD4+T cells in moderate to severe active SLE patients (3.0 ±2.0)％ was significantly increased compared to patients with mild or inactive (1.0±1.4)％(t=2.574, P<0.05) and normal controls (0.3±0.3)％ (t=5.149, P<0.01). The percentages of PD-1hiCXCR5- cells within CD4+ T cells from SLE patients were positively related with systemic lupus erythematosus disease activity index (SLEDAI) (r=0.475, P=0.0297). SLE patients in serum anti-dsDNA antibodies positive group (2.7±2.1)％displayed a higher percentage of PD-1hiCXCR5-cells within CD4+T cells than patients in serum anti-dsDNA antibodies negative group (0.6 ±0.5)％ (t=2.303, P<0.05). The percentages of PD-1hiCXCR5-cells within CD4+T cells from SLE patients were positively correlated with anti-dsDNA antibody titers. Conclusion The percentages of PD-1hiCXCR5- cells within CD4+ T cells from SLE patients are increased and are positively correlated with SLEDAI and anti-dsDNA antibody levels. Increased percentage of PD-1hiCXCR5-cells within CD4+T cells might play an important role in the pathogenesis of SLE.

ObjectiveTo explore the effects of different emulsion mixtures and emulsification methods on the inflammation severity in an experimental autoimmune uveitis （EAU） model in rats， and to analyze the characteristics of the current EAU model. MethodEAU was induced in Lewis rats by subcutaneous injection of interphotoreceptor retinoid-binding protein （IRBP） 1177-1191 emulsified with Freund's complete adjuvant （CFA）， with or without intraperitoneal injection of pertussis toxin （PTX）. Slit lamp examination， HE staining， and optical coherence tomography were used to evaluate factors affecting EAU modeling， including different doses of the emulsion mixture （IRBP1177-1191， PTX， and inactivated Mycobacterium tuberculosis） and four different emulsification methods. The classification， characteristics， modeling methods， advantages， and disadvantages of EAU animal models were summarized and analyzed based on the clinical diagnostic criteria and syndrome characteristics of chronic uveitis in both traditional Chinese medicine （TCM） and western medicine， to evaluate the consistency between TCM and western medical syndromes. ResultIncreasing the dose of inactivated M. tuberculosis and antigen peptide in the emulsion mixture exacerbated the anterior segment inflammation in EAU rats. Increasing the injection of PTX also exacerbated anterior segment inflammation and increased retinal thickness in EAU rats. The severity of the EAU model was closely related to the emulsification method used. All four emulsification methods successfully induced EAU in rats. Comparatively， the ultrasonic cell disruptor and T10 basic disperser achieved successful emulsification in a short time. The degree of emulsification of the mixture also influenced the severity of the EAU model in rats. The existing EAU animal model shows a high degree of consistency with western medical diagnoses and the main ocular syndromes in TCM. ConclusionIRBP1177-1191， PTX， inactivated M. tuberculosis， and emulsification methods can affect the severity of the EAU model through different pathways. The existing EAU animal models can simulate the clinical characteristics of western medicine well but lack the etiology， pathogenesis， and syndrome characteristics of TCM. Therefore， it is necessary to construct an EAU animal model that combines disease and syndrome characteristics.
