Objective To study the effect of misoprostol combined with psychological intervention on the patients with induced abortion.Methods 200 cases with intrauterine pregnancy in the first affiliated hospital of Wenzhou medical university from March 2015 to August 2016 were selected as the research object in this study.They were randomly divided into the control group and the experimental group, 100 cases in each group.After using iodophor to rinse the vagina, 600ug misoprostol were placed in posterior vaginal fornix in the experimental group 2 hours before operation.Before the operation, the nursing staff should inform the patient of the relevant surgical attention points, eliminate the negative emotions such as anxiety and anxiety, and improve the treatment compliance.During the operation, the nursing staff should pay attention to the psychological state of the patients.The control group were given lidocaine locally.The clinical efficacy in the groups were compared.Results After treatment, the analgesia obvious effective rate in the experimental group was 38%, the analgesia effective rate was 52%.The analgesia obvious effective rate in the control group was 16%, the analgesia effective rate was 49%.The analgesic effect in the experimental group was significantly higher than that in the control group, with statistical significance (P<0.05).After treatment, the effective rate of cervical dilation in the experimental group was 45%, the effective rate was 66%.The degree of cervical dilatation in the experimental group was significantly better than that in the control group.The amount of intraoperative bleeding was significantly less than that in the control group, with statistical significance (P<0.05).Conclusion Misoprostol combined with psychological intervention can improve the clinical effect of artificial abortion to a large extent, relieve the pain of patients and shorten the operation time.

Objective; To study estrogen receptor gene Xbal and Pvu Ⅱ polymorphisms in patients with aggressive periodontitis (AgP). Methods; Xbal and Pvu Ⅱ DNA was extracted by Chelex-100 and amplified by PCR from buccal swabs of 48 cases of AgP patients and 60 normal controls. The PCR products were analyzed by polymerase chain reaction linked fragment length polymorphism (PCR-RFLP) assay. Results: There were significant differences of the distribution of Xba I genotype between AgP group and control group, female AgP group and female control group, male AgP group and male control group(P<0.05). There was no difference of Pvu D genotype distribution between patient group and control group (P>0.05). Multivariate Logistic Regression Analysis showed that male group was less susceptible to AgP than female group(OR =0. 352), the older was less susceptible to AgP than the younger(OR =0.950), and the xxXx genotype was less susceptible to AgP than XX genotype [OR(Xx) =0.224, OR(xx) = 0.678). Conclusion: Specific relationship is found between the susceptibility of AgP and the ER gene-Xbal polymorphism. People with XX genotype is more susceptive to AgP than xx, Xx genotypes.

Aim To study the effects of aspirin on increasing the atherosclerotic plaque stability and its possible mechanisms.Methods The hyperlipidemic atherosclerotic model was generated in male New Zealand rabbits given high fat diet and endothelial abrasion of abdominal aorta.These rabbits were then treated with aspirin 5～20 mg?kg-1 for 4 weeks.At experimental end,the plaques were evoked into rupture by injection of Russell's viper venom and histamine.Areas of thrombosis on atherosclerotic aorta were determined by image analysis,morphologic character of plaque rupture was examined by light microscope,the protein expression of macrophages was detected by immunohistochemistry,and the mRNA expression of COX-2 and MMP-2 was determined by hybridization in situ,respectively.Results Aspirin at doses of 5～10 mg?kg-1 was able to inhibit thrombosis on atherosclerotic plaque(P

A sensitive and effective method for determination of 16 kinds of antibiotics, including tetracycline, sulfonamide, fluoroquinolone and macrolide, in livestock and poultry manure using solid phase extraction-ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established.Aiming at the chemical properties and sample impurities of the target, the parameters such as mass spectrum conditions, types of extraction and ultrasonic power were optimized.Finally, the samples were extracted with 50% acetonitrile in phosphate buffer solution (pH =4) for three times, followed by ultrasonic steaming, centrifugal and rotary, dilution, and purified by SAX-HLB.After sample loading, the solid phase was washed with 10 mL of methanol-acetone (80∶20, V/V), evaporated to near dryness at 35℃, and then re-dissolved and vortex mixed in 1 mL of 0.1% formic acid∶methanol (1∶1, V/V).The extracts were analyzed with UPLC-MS/MS and calculated by external standard method based on the monitored product ion.The results indicated that the average spiked recoveries of tetracycline, sulfonamide, fluoroquinolone and macrolide in manure were 56.4%-94.6% with relative standard deviations (RSDs) of 2.6%-19.8%, the LODs (S/N=3) were 0.01-2.50 μg/kg, and the LOQs (S/N=10) were 0.05-7.90 μg/kg.The method was simple with high stability, high sensitivity and good reproducibility, and suitable for the simultaneously determination of many antibiotics in animal and poultry manure.

Objective To evaluate the clinical efficacy and safety of combined ozone hydrotherapy for the treatment of atopic dermatitis(AD). Methods A total of 60 patients with moderate or severe AD aged from 6 to 65 years were enrolled, and randomly and equally divided into a test group and a control group. Both the two groups were treated with oral levocetirizine capsules 5 mg once a day, topical tacrolimus ointment twice a day, and topical moisturizers. The test group was additionally treated with ozone hydrotherapy 3- 5 times every week. The treatment lasted 2 weeks. The severity scoring of atopic dermatitis (SCORAD) score, visual analog scale (VAS) score, dermatology life quality index (DLQI) or children′s dermatology life quality index (CDLQI) score were assessed before and after the treatment, and compared between the two groups. Enzyme?linked immunosorbent assay(ELISA) was performed to measure the levels of interleukin?4(IL?4)and nerve growth factor(NGF)in peripheral blood from the patients before and after the treatment. Results After 2?week treatment, the SCORAD scores, VAS scores and DLQI/CDLQI scores significantly decreased from 42.13 ± 16.03, 7.14 ± 2.12 and 14.92 ± 5.94 before the treatment to 27.3 ± 11.01, 2.23 ± 1.31 and 9.69 ± 4.17 respectively in the test group(all P<0.05), and from 43.36 ± 17.78, 6.45 ± 1.29 and 15.15 ± 5.40 to 39.65 ± 16.67, 3.32 ± 0.87 and 12.84 ± 5.37 respectively in the control group(all P<0.05). In addition, all the three scores were significantly lower in the test group than in the control group after 2?week treatment(all P<0.05). A significant decline was also observed in the levels of IL?4 and NGF in peripheral blood in the two groups at the end of the treatment compared with those at baseline(all P<0.05), and the magnitude of decline in IL?4 levels was significantly higher in the test group than in the control group(t=8.57, P<0.05), while that in NGF levels was insignificantly different between the two groups(t=9.51, P>0.05). Conclusion Combined ozone hydrotherapy can effectively and safely improve the condition of patients with AD, likely by decreasing the levels of IL?4 in peripheral blood.

The clinical evidences of the guideline came from clinical trials based evidence-based medicine. Applied principle of the evidence was: systematic reviews, RCTs, the results from multiple factors ana-lysis, consensus, especially combined with Chinese experience and some lung cancer guidelines used in USA or Europe. All doctors who use the guideline in making therapeutic strategy must combine patients' conditions with the knowledge of biological behavior, dynamic change and response to treatment of lung cancer.

Objective:To establish and preliminarily validate a nomogram model for predicting the risk of retinal vein occlusion (RVO).Methods:A retrospective clinical study. A total of 162 patients with RVO (RVO group) diagnosed by ophthalmology examination in The Second Affiliated Hospital of Xi'an Jiaotong University from January 2017 to April 2022 and 162 patients with age-related cataract (nRVO group) were selected as the modeling set. A total of 45 patients with branch RVO, 45 patients with central RVO and 45 patients with age-related cataract admitted to Xi'an Fourth Hospital from January 2022 to February 2023 were used as the validation set. There was no significant difference in gender composition ratio ( χ2=2.433) and age ( Z=1.006) between RVO group and nRVO group ( P=0.120, 0.320). Age, gender, blood routine (white blood cell count, hemoglobin concentration, platelet count, neutrophil count, monocyte count, lymphocyte count, erythrocyte volume, mean platelet volume, platelet volume distribution width), and four items of thrombin (prothrombin time, activated partial thrombin time, fibrinogen, and thrombin time) were collected in detail ), uric acid, blood lipids (total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, lipoprotein a), hypertension, diabetes mellitus, coronary heart disease, and cerebral infarction. Neutrophil/lymphocyte ratio and platelet/lymphocyte ratio were calculated. The single logistic regression was used to analyze the clinical parameters of the two groups of patients in the modeling set, and the stepwise regression method was used to screen the variables, and the column graph for predicting the risk of RVO was constructed. The Bootstrap method was used to repeated sample 1 000 times for internal and external verification. The H-L goodness-of-fit test and receiver operating characteristic (ROC) curve were used to evaluate the calibration and discrimination of the nomogram model. Results:After univariate logistic regression and stepwise regression analysis, high density lipoprotein, neutrophil count and hypertension were included in the final prediction model to construct the nomogram. The χ2 values of the H-L goodness-of-fit test of the modeling set and the validation set were 0.711 and 4.230, respectively, and the P values were 0.701 and 0.121, respectively, indicating that the nomogram model had good prediction accuracy. The area under the ROC curve of the nomogram model for predicting the occurrence of post-stroke depression in the modeling set and the verification set was 0.741 [95% confidence interval ( CI) 0.688-0.795] and 0.741 (95% CI 0.646-0.836), suggesting that the nomogram model had a good discrimination. Conclusions:Low high density lipoprotein level, high neutrophil count and hypertension are independent risk factors for RVO. The nomogram model established based on the above risk factors can effectively assess and quantify the risk of post-stroke depression in patients with cerebral infarction.

Objective:To compare the efficacy and safety of different dosages of new drugs in the treatment of PsA by using network meta-analysis.Methods:Three medical databases (PubMed, Web of Science, Cochrane Library) were searched for the studies that compared the efficacy and safety of 4 new drugs (secukinumab, ixekizumab, apremilast, tofacitinib) with different dosages in the treatment of PsA. Data from included studies were analyzed by Stata 15.0.Results:A total of 16 RCTs were included. The results of the network meta-analysis showed that: (1) Among the overall patients, in terms of ACR20 response rate, the larger the surface under the cumulative ranking (SUCRA), the more effective it is. Secukinumab 300 mg Q4W(96.1%) had the best efficacy, followed by ixekizumab 80 mg Q4W(79.0%), ixekizumab 80 mg Q2W(75.1%), secukinumab 150 mg Q4W(73.2%), apremilast 30 mg BID(50.6%), apremilast 20 mg BID(38.6%), tofacitinib 5 mg BID(18.1%), tofacitinib 10 mg BID(17.7%) and placebo(2.0%). (2) In terms of PASI75 response rate, the larger the area under the SUCRA curve, the more effective it is. Ixekizumab 80 mg Q4W(96.1%) had the best efficacy, followed by ixekizumab 80 mg Q2W(88.7%), secukinumab 300 mg Q4W(75.6%), secukinumab 150 mg Q4W(63.3%), apremilast 30 mg BID(44.5%), apremilast 20 mg BID(38.4%), tofacitinib 10 mg BID(30.0%), tofacitinib 5 mg BID(12.5%) and placebo(1.0%). (3) Among the overall patients, in terms of safety, the smaller the area under the SUCRA curve, the higher the safety it is. Secukinumab 300 mg Q4W (17.3%) has the best safety. (4) The results of subgroup analysis showed that in terms of ACR20 response rate, ixekizumab 80 mg Q2W(85.3%) had the best efficacy in bDMARDs-na?ve patients, while in bDMARDs-IR patients, secukinumab 300 mg Q4W(83.9%) had the best efficacy.Conclusion:Among all patients, secukinumab 300 mg Q4W is the best in terms of ACR20 response rate and safety, but ixekizumab 80 mg Q4W is more effective in improving PsA lesions comparing yo other drugs.

Objective To investigate the diagnostic value of neuron-specific enolase(NSE),central nervous system specific protein (S100β),interleukin-6 (IL-6) in sepsis-associated encephalopathy (SAE).Methods Clinical data of patients admitted to ICU and diagnosed with sepsis were collected from January 2015 to June 2016 in Xiangya Hospital,Central South University.SAE was defined as cerebral dysfunction in the presence of sepsis that also fulfilled the exclusion criteria.The acute physiology and chronic health score (APACHE Ⅱ),sequential organ failure assessment (SOFA),NSE,S100β,IL-6,ICU stay time and 28-day mortality were compared between the two groups.NSE,S1003 and IL-6 were measured on the 1 st and 3rd day in ICU to determine the optimal cut-off value of SAE.Results Among 59 enrolled patients,36 were assigned to SAE group while 23 were non-SAE group.The SAE group had a significantly higher APACHE Ⅱ and SOFA scores,as well as the length of ICU stay (P ＜ 0.01).The levels of NSE,S1003 and IL-6 in the two groups both increased on the 1st day,and decreased on the 3rd day.The level of NSE on the 1st day [19.28 (13.00,30.52) μg/L vs 16.61 (7.58,22.01 μg/L)] and the 3rd day[16.03 (9.40,21.29) μg/L vs 11.39(8.49,15.00) μg/L,P=0.029],IL-6 on the 1st day[676.25(81.34,5 000.00) mg/L vs [209.10(42.27,648.20) mg/L,P =0.005] and the 3rd day [157.10 (72.85,687.63) mg/L vs 55.92 (31.62,177.00) mg/L,P =0.026] of SAE group was significantly higher than those of non-SAE group.However S100β between groups on the 1st day [0.33(0.15,0.54) μg/L vs 0.23(0.16,0.53) μg/L] and the 3rd day[0.19(0.10,0.29) μg/L vs 0.10(0.05,0.17) μg/L] was neither significant (P ＞0.05).The diagnostic values for SAE of NSE,S1003 and IL-6 were 14.36 μg/L,0.14 μg/L and 91.305 mg/L with sensitivity 61.1％,61.1％,72.2％ and specificity 73.9％,69.6％,69.6％,respectively.The diagnostic AUC of NSE and IL-6 combination was 0.774,95％ CI 0.651-0.896.Conclusion All sepsis patients have different degrees of brain injury.NSE combined with IL-6 on the 3rd day in ICU demonstrates the diagnostic significance of SAE.
