Objective To explore the value of combined detection of carbohydrate antigen 125(CA125),human epididymis secre-tory protein 4 (HE4)and plasma D-dimer in early diagnosis of ovarian cancer.Methods Fifty-six patients with ovarian cancer and 50 patients with benign ovarian tumors in the gynecology department of our hospital from January 2014 to June 2016 were selected. Contemporaneous 50 women undergoing healthy physical examination were selected.The chemiluminescence method was adopted to determine serum CA125 and HE4 levels,and the immune turbidimetry method was adopted to detect plasma D-dimmer level.Their early diagnostic values for ovarian cancer were comparatively analyzed.Results The serum CA125 and HE4 levels and plasma D-di-mer level in the cancer group were significantly higher than those in the control group with statistical difference(P<0.05),moreo-ver HE4 had higher sensitivity(89.28%)and higher specificity (88.00%)for detecting ovarian cancer.In the 3-index combined de-tection,sensitivity and specificity were greatly improved.Conclusion The combined detection of CA125,HE4 and plasma D- dimer can improve the accuracy of early diagnosis of ovarian cancer.

【Objective】To observe the influence of temperature and perfusate modifier on in-vitro mass transfer coefficient of microdialysis with sinomenine as a model drug.【Methods】The in-vitro relative recovery(RR) was assayed by HPLC at different temperatures and in perfusate including different concentrations of alcohol,and then the mass transfer coefficient was calculated.【Results】In-vitro RR increased with the temperature and the concentrations of alcohol,so did the mass transfer coefficient.【Conclusion】Temperature and alcohol at different concentrations have an effect on RR and mass transfer coefficient of microdialysis with sinomenine as a model drug.

AIM: The transdermal absorption data of sinomenine patch was fitted by grey model GM(1,1) and compared with other models. METHODS: The transdermal absorption experiment was carried out with Franz diffusion cell and the GM(1,1) was established by accumulation generation operator (AGO). RESULTS: The fitting precision was compared by using mean relative error and grey absolute correlation degree as evaluation criterion. CONCLUSION: The fitting precision of GM(1,1) is as high as acceptable.

Objective To study the effect of skin stratum corneum on transdermal absorption characteristic of Sinomenine Liposome Patch. Methods The normal and stripped stratum corneum skin of back and abdomen was used to study the transdermal absorption characteristic by Franz method. The transdermal absorption sample was taken at the preset sampling time point. The sample content was determined by HPLC. The cumulative transdermal amount of per unit area was fitted with sampling time point, the transdermal rate constant (J value) was selected as comparative standard. Results The transdermal rate constant (J) of skin with stratum corneum stripped increased obviously than that of the normal skin, so was the released rate constant. Conclusion The skin stratum corneum has an notable impact on transdermal absorption characteristic of Sinomenine Liposome Patch. When the skin of experimental animal being prepared, the integrality should be paid more attention.

miniature swines were randomly divided into irradiation group ( n =7) and control group ( n =8). Immediately after balloon overstretch injury to LAD, radioactive liquid perfused balloon irradiation was performed at the target segment; radioactive dose was 24Gy. 35 days after the operation, the target segments were harvested to perform histologic and morphologic study (HE, MS, VVG) and immunohistochemical study (PCNA, ? smooth muscle actin). Results showed that the lumen area was significantly larger, the neointima area and vascular stenosis level were smaller, and less PCNA positive cells were present in the vascular wall in the irradiation group than in the control group ( P all

Three problems of treatment based on syndrome differentiation, TBSD are discussed here. Firstly, in allusion to the diversity of the concept of TBSD, the due medical concept of it are discussed and analyzed. Hence, the actual difference and sameness, the due relationship as well as the principle of management between syndrome differentiation and disease differentiation are fully compared. Finally, the concrete operation procedure of syndrome differentiation and disease differentiation are expounded. The author detailedly introduced particular cognition to standardized operation of TBSD attained from Yao Hesheng, a famous physician in Jiangxi Province.

AIM: To investigate the feasibility to inhibit the expression of MHCⅡ by special siRNA targeting class Ⅱ major histocompatibility complex (MHC Ⅱ) transactivator (CⅡTA), which might regulate MHC Ⅱexpression for suppressing immune rejection. METHODS: Five different siRNA were designed, synthesized and transfected into freshly isolated rat corneal keratocytes. At 24 hours posttransfection, the changes of MHC Ⅱexpression were detected by flowcytometry, and the mRNA abundance of CⅡTA and MHC Ⅱ was measured by FQ-PCR after inducing with recombinant rat interferon-gamma (IFN-?). RESULTS: Different siRNA showed different reduction in MHC Ⅱ and CⅡTA expression compared with the control (P

The paper is to report the study of pharmacokinetics of transdermal administered nicotine in the brain of freely moving rat by using microdialysis with stable labeled isotope as internal standard. The pharmacokinetic behavior of nicotine in Sprague Dawley rat brain was investigated after intranasal administration (3.75 mg). Brain fluid samples were collected by intracerebral microdialysis with DL-nicotine as internal standard. Concentrations of nicotine and DL-nicotine in the sample were measured by HPLC-MS/MS. Main pharmacokinetic parameters were calculated and analyzed by Das 2.0 pharmacokinetic software. The recovery of nicotine and the delivery of DL-nicotine were the same. The fate of absorption and distribution was two compartment model and the values of t1/2alpha was 170.31 min, t1/2beta was 263.30 min and the AUC(0-infinity) was 2.75 x 10(5) microg x L(-1) min separately. DL-nicotine can be used to calibrate the recovery of nicotine, and the new method of stable isotope microdialysis can be used to study the pharmacokinetics of freely moving rat. It will make sense for the treatment of addiction of tobacco and provide a new thought for the research of pharmacokinetics-pharmacodynamic combination.

Objective To design nursing occupational safety and health curriculum reasonably.Methods With a semi-structured interview outline,focus group interviews among eight clinical nursing and nursing education specialists were conducted to develop the occupational safety and health curriculum design.Results It was important to set up nursing occupational safety and health curriculum.The main object,contents,teaching and evaluation methods were identified.Conclusions Occupational safety and health curriculum can be involved in nursing curriculum system to reduce occupational hazards and maintain physical and mental health of nursing students.

Objective Screening the potential lncRNAs of KIAA1456 inhibiting ovarian cancer cells.MethodsImmunofluorescence was used to detect the expression of KIAA1456 in HO8910PM ovarian cancer cell.Microarray was performed to identify differently expressed lncRNAs in HO8910PM ovarian cancer cells overexpressed KIAA1456 as compared with the normal control group. The interesting candidate lncRNAs were verified by real-time quantitative PCR.Constructing RNAi lentiviral vector targeting KIAA1456 gene in HO8910PM ovarian cancer cells, RT-qPCR and Western blot was performed to measure the interference efficiency.Differentially expressed lncRNAs were validated by RT-qPCR after KIAA1456 knock-down.Results KIAA1456 mainly expressed in nucleus of HO8910PM cell.A total of 654 differently expressed lncRNAs were identified in the KIAA1456-overexpressed group compared with the control group with a set filter fold-change ≥1.2, the most aberrantly expressed lncRNAsincluding down-regulated gene SSX8 and up-regulated genes SNORD14D,SNORA26,lncRNA-ENST00000384488.The results of the RT-qPCR were consistent with the data from the microarray.The shRNA interference vectors targeting the KIAA1456 gene were successfully constructed, SSX8 was up-regulated, and SNORD14D,SNORA26,lncRNA-ENST00000384488 were down-regulated after knockdown the expression of KIAA1456 in the HO8910/PM ovarian cancer cells.Conclusions KIAA1456 inhibits proliferation of ovarian cancer by regulating correlative lncRNAs, which may provide a new target for the diagnosis and treatment of ovarian cancer.
