Serum HE4 levels of patients with serous adenocarcinoma ,endometrial adenocarcinoma or other ovarian cancer were markedly high-er than that with mucinous adenocarcinoma (P<0 .01) .Serum HE4 levels of patients with stage Ⅲ ,Ⅳ ovarian cancer were obvious-ly higher than those with Ⅰ ,Ⅱ stage(P<0 .01) .Conclusion HE4 detection has clinical value for the auxiliary diagnosis of ovarian cancer .

Objective To evaluate the effect of Xuefu-Zhuyu decoction combined with interactive acupuncture and ibuprofen sustained-release capsule in the treatment of acute lumbar sprain. Methods A total of 102 patients with acute lumbar sprain were randomly divided into two groups, 51 in each group.The control group received ibuprofen sustained-release capsules orally. The study group was treated with Xuefu-Zhuyu decoction combined with interactive acupuncture on the basis of the control group. Both groups were treated for 2 weeks. The degree of low back pain was assessed by VAS and the improvement of lumbar function was assessed by modified Japanese Orthopaedic Association Scores (M-JOA). The Oswestry dysfunction index (ODI) was used to evaluate the degree of lumbar dysfunction. The serum hs-CRP, IL-6, IL-10 and prostaglandin E2 (PGE2) level was detected by ELISA. The clinical efficacy was evaluated. Results The total effective rate was 80.4% (41/51) in the study group and 62.8% (32/51) in the control group. There was significant difference between the two groups (χ2=3.903, P=0.048). After treatment, the VAS (1.85 ± 0.40 vs. 4.06 ± 0.67, t=20.226), M-JOA (4.41 ± 1.35 vs. 11.18 ± 2.25, t=18.426), and ODI (9.66 ± 3.34 vs. 16.37 ± 3.64, t=9.700) in the study group were significantly lower than those in the control group (P<0.01). The serum level of hs-CRP, IL-6, IL-10 and PGE2 in the study group were significantly lower than those in the control group after treatment (t were 6.694, 8.416, 22.110 and 12.137, respectively, all P s<0.01). Conclusions The Xuefu-Zhuyu decoction combined with interactive acupuncture and ibuprofen sustained-release capsule can improve the degree of lumbago and lumbar dysfunction in patients with acute lumbar sprain, reduce the level of serum inflammatory cytokines, and improve the clinical efficacy.

Objective:To investigate the prevalence of influenza, pneumococcal, hepatitis B virus (HBV), human papillomavirus (HPV), and varicella zoster virus (VZV) vaccination in patients with systemic lupus erythematosus (SLE), and to analyze the factors related to vaccination.Methods:Data were obtained from 1 203 patients with SLE, via a multi-center web-based survey using an online questionnaire. Data about their social conditions, clinical presentations, willingness for being vaccinated, vaccination within 5 years were collected. Demographic data were shown by descriptive analysis. Chi-square and logistic regression analysis were used to assess the power of related indexes as predictors of vaccination.Results:The vaccination rates of influenza, pneumococcal, HBV, HPV, and VZV were 5.49% (66/1 203), 0.66% (8/1 203), 2.08% (25/1 203), 3.82% (46/1 203), and 0.17% (2/1 203), respectively. Data analysis showed that higher education ( χ2=30.94, P<0.001) and higher income ( χ2=10.70, P=0.001) had greater effects on influenza vaccination. There was a relationship between HPV vaccination and higher education ( χ2=20.96, P<0.001), higher income ( χ2=20.56, P<0.001), younger age ( χ2=8.54, P=0.001), and single ( χ2=5.63, P=0.018). Male ( χ2=10.27, P=0.001) and higher education ( χ2=4.52, P=0.034) were associated with HBV vaccination. The multivariate logistic regression analysis revealed that higher education [ OR (95% CI)=2.14 (1.10, 4.18), P=0.026], having children under 18 years-old [ OR(95% CI)=1.802(1.02, 3.18), P=0.042], and hydroxychloroquine usage [ OR(95% CI)=2.55(1.06, 6.15), P=0.037], had a positive correlation with influenza vaccination. Male [ OR(95% CI)=4.24(1.37, 13.08), P=0.012], had an impact on HBV vaccination. The factors related to HPV vaccination included age <45 [ OR (95% CI)=0.93(0.89, 0.97), P=0.001], higher education [ OR(95% CI)=2.28(1.11, 4.65), P=0.024], higher income [ OR(95% CI)=2.68(1.32, 3.41), P=0.006] and the usage of immunosuppressive agents [ OR(95% CI)=1.92(1.03, 3.59), P=0.041]. Conclusion:The prevalence of vaccination in patients with SLE is low. Patients with higher education and income are more likely to being vaccinated.

Objective To explore the relationship between glycemic instability index(GLI),peripheral blood CD4+/CD8+,neutrophil-to-lymphocyte ratio(NLR),red blood cell distribution width(RDW),neutrophil gelatinase-associated lipocalin(NGAL),and the occurrence,condition and prognosis of stroke-associated pneumonia(SAP).Methods According to the occurrence of SAP within 7 d after onset,550 patients with acute cerebral infarction were divided into the study group(129 cases with SAP)and the control group(421 cases without SAP).GLI,peripheral blood CD4+/CD8+,NLR,RDW and NGAL levels were measured.The differences in the above indicators were compared between the study group and the control group,as well as SAP patients with different conditions and prognoses.The relationship between above indicators and the occurrence,condition and prognosis of SAP was discussed.The prognostic values of each indicator and combination of indicators were analyzed.Results GLI,NLR,RDW and NGAL levels were higher in the study group,the medium to high risk group and the poor prognosis group than those in the control group,the low-risk group and the good prognosis group.CD4+/CD8+was lower than that in the corresponding group(P＜0.05).Multivariate Logistic regression analysis showed that higher GLI and NLR were independent risk factors for acute cerebral infarction complicated with SAP,and higher GLI,NLR,RDW and NGAL were independent risk factors for the medium to high risk conditions in SAP patients,while higher levels of CD4+/CD8+were protective factor for high-risk diseases in patients with concurrent SAP and SAP(P＜0.05).Higher GLI,NLR and RDW were independent risk factors for poor prognosis in patients with SAP(P＜0.05).ROC curves indicated that the AUC of the combination of GLI,NLR and RDW for evaluating poor prognosis in patients with SAP was better than that of GLI or RDW.Conclusion Changes in GLI,CD4+/CD8+and NLR are influencing factors for the occurrence of SAP.GLI,CD4+/CD8+,NLR,RDW and NGAL are influencing factors for the severity of SAP patients.GLI,NLR and RDW are associated with poor prognosis in SAP patients,and all three have certain predictive effective in predicting the prognosis of SAP patients,and NLR has the highest predictive efficacy.
