Objective:To explore the association between greenspace morphology and the risk of severe fever with thrombocytopenia syndrome (SFTS) in Shandong Province.Methods:The SFTS cases data and land use data in Shandong province from 2018 to 2022 were collected, 6 landscape indices were calculated through Fragstats 4.2 software, and a negative binomial regression model was used to quantitatively evaluate the effect. Meteorological and socioeconomic factors during the same period were controlled as covariates. Subgroup analysis were conducted by age, gender and occupation. The percentage of relative risk[(RR-1)×100%] with 95% confidence interval (95% CI) was used as effect estimates. Results:There was a significant association between greenspace morphology and the risk of SFTS. Every 1% increase in the percentage, the mean area, fragmentation, aggregation, connectedness, and complexity of the shape of greenspace will lead to an increase in the risk of SFTS by 4.28% (95% CI: 2.88%-5.68%), 3.56% (95% CI: 1.06%-6.12%), 2.43% (95% CI: 1.38%-3.61%), 2.22% (95% CI: 1.39%-3.11%), 0.41% (95% CI: 0.26%-0.56%), 0.26% (95% CI: 0.10%-0.41%), respectively. There were statistically significant differences in the association between greenspace morphology and the risk of SFTS among different age and occupational subgroups. The elderly and farmers were the more susceptible to the changes in the percentage of greenspace and the complexity of the shape of greenspace. Conclusions:Greenspace morphology is related to the risk of SFTS. The elderly and farmers are vulnerable populations.

BACKGROUND:Compensatory changes in sagittal parameters of the cervicothoracic spine after orthopedic surgery in patients with lumbar degenerative scoliosis and their intrinsic relationship,as well as the impact of these changes on quality of life,are still lacking.OBJECTIVE:To evaluate the compensatory alignment of cervical and thoracic vertebrae after correction of lumbar degenerative scoliosis.METHODS:103 patients who underwent surgical correction of lumbar degenerative scoliosis were included in this study.Patients'demographic characteristics and spinal sagittal parameters were assessed,and prediction equations between changes in cervical sagittal parameters and lumbar deformity correction were attempted.Simultaneously,the SRS-22 scale was used to assess the quality of life of patients and to explore the relationship between the compensatory changes of the cervical and thoracic spine after correction and the patients'health-related quality of life.RESULTS AND CONCLUSION:(1)At 3 months and 2 years after surgery,all indicators of the cervical spine and thoracic spine were significantly improved compared with those before surgery(P＜0.05),but there was no significant change at 3 months after surgery compared with 2 years after surgery(P＞0.05).At 3 months and 2 years after surgery,the lumbar spine parameters including lumbar lordosis,C7-S1 sagittal vertical axis,and pelvic incident-lumbar lordosis had significant changes compared with those before surgery(P＜0.05),but the change was not significant at 3 months after surgery compared with 2 years after surgery(P＞0.05).(2)Correlation analysis showed that the lumbar lordosis was highly correlated with the C3-C7 cervical lordosis,C1-C7 cervical lordosis,C2-7 sagittal vertical axis,thoracic inlet angle,and C7-S1 sagittal vertical axis(|r|≥ 0.5,P＜0.000 1).The lumbar lordosis was correlated with the thoracic kyphosis(r=-0.280).(3)Two prediction formulas were established for compensatory changes in cervical spine:cervical lordosis=0.524x,lumbar lordosis=-6.612,C2-7 sagittal vertical axis=-0.263x,and lumbar lordosis=-5.436(P＜0.05,R2＞0.6).(4)When postoperative C2-7 sagittal vertical axis was between 14.4 and 26.8 mm;cervical lordosis was between 9° and 41°,lumbar lordosis was between 42.7° and 68.7°,and sagittal vertical axis was between-40 and 40 mm,patients had better quality of life recovery.(5)It is indicated that significant compensatory changes in the sagittal plane of the cervical spine can be observed after correction of lumbar degenerative scoliosis.We found that each 1° increase in lumbar lordosis was associated with a corresponding increase of about 0.5° in cervical lordosis and a corresponding decrease of about 0.3 mm in the vertical axis of the C2-7 sagittal plane.Patient satisfaction was higher if compensatory changes were closer to normal sagittal plane.

Objective : To investigate the predictive value of serum homocysteine(HCY) level on the risk of miscarriage in polycystic ovary syndrome(PCOS) patients undergoing frozen-thawed embryo transfer(FET). Methods: 536 PCOS patients and 550 non-PCOS patients with fallopian tube factors(control group) retrospectively were analyzed.The basic characteristics and pregnancy outcomes were compared between the two groups.Also, the basic characteristics between the miscarriage group and the live birth group in PCOS patients were compared.The predictive value of Hcy on the miscarriage of PCOS patients after FET treatment was analyzed. Results: Compared with the control group, body mass index(BMI),testosterone(T),Hcy, fasting insulin(FINS),homeostasis model assessment of insulin resistance(HOMA-IR),total cholesterol(TC),number of retrieved oocytes and miscarriage rate increased in PCOS group, while high density lipoprotein-cholesterol(HDL-C),high-quality embryo rate and live birth rate decreased, and the differences were statistically significant(P<0.05).Among PCOS patients, Hcy, FINS and HOMA-IR increased in the miscarriage group compared with live birth group, and the differences were statistically significant(P<0.05).Hcy, FINS and HOMA-IR were independent risk factors for miscarriage in PCOS patients, and the predictive value of Hcy for miscarriage in PCOS patients was greater than FINS and HOMA-IR,and the area under ROC curve(AUC) was 0.829(95%CI=0.755-0.902,P<0.001),the cut-off value was 15.975 μmol/L with a 79.0% sensitivity and a 87.4% specificity, which indicated high predictive value for miscarriage in patients with PCOS. Conclusion Serum Hcy level significantly increased in PCOS patients, which has an important predictive value for miscarriage after FET treatment.

OBJECTIVES: Lymph node metastasis affects the initial treatment strategy for cervical cancer and is hard to be diagnosed in clinical practice.This paper aims to explore the relationship between calcium-binding A9 (S100A9) and lymph node metastasis (LNM) in cervical cancer, and to determine the predictive value of S100A9 for LNM in cervical cancer. METHODS: We performed a retrospective cohort study and collected the pathological data, follow-up data, and paraffin tissue samples of 99 patients with cervical cancer who underwent modified extensive or extensive hysterectomy plus pelvic lymphadenectomy at the Department of Gynecology, Xiangya Hospital, Central South University from January 2013 to December 2018. Immunohistochemistry was used to detect the expression of S100A9 in cervical cancer tissues, and the correlation between S100A9 expression and LNM of cervical cancer, or clinicopathological characteristics were analyzed. The receiver operating characteristic (ROC) curve was used to establish a predictive model for LNM of cervical cancer, and Chi-square test of four-grid table was used to evaluate the diagnostic value of S100A9 for LNM in cervical cancer. RESULTS: The expression of S100A9 was significantly correlated with LNM. The S100A9 immunohistochemical semi-quantitative score of the LNM group was significantly higher than that in the non-lymph node metastasis group (<0.001). Moreover, the expression of S100A9 was significantly correlated with histological type, stromal invasion, lymphatic vessel invasion, or LNM (<0.05). The cut-off of the ROC curve for predicting LNM was 5, with the Youden index of 0.649 and the area under the ROC curve of 0.863. The disease-free survival and overall survival in the S100A9 positive group were significantly shorter than those in the negative group (<0.05). S100A9 alone had a sensitivity of 71.4%, a specificity of 91.5%, and an accuracy of 85.1% for diagnosing LNM. Imaging had a sensitivity of 32.1%, a specificity of 74.6%, and an accuracy of 60.9%. Combination of S100A9 with image examination in parallel test had a sensitivity of 85.7%, a specificity of 71.2%, and an accuracy of 75.9%, while combination of S100A9 and image examination in serial test had a sensitivity of 17.9%, a specificity of 98.3%, and an accuracy of 72.4%. CONCLUSIONS S100A9 may be associated with LNM in cervical cancer. S100A9 shows a promising perspective in predicting LNM in cervical cancer. Combination of S100A9 and image examination in serial test has a high specificity for LNM.

To investigate the correlation between soluble resistance-related calcium-binding protein (Sorcin) and chemoresistance or overall survival in patients with ovarian cancer.
 Methods: We detected the expression of Sorcin in 27 cases of chemoresistant ovarian cancer tissue and 37 cases of sensitive ovarian cancer tissue by immunohistochemistry, and analyzed the relationship between the protein and clinicopathological features or chemoresistance of ovarian cancer. Log-rank test was used to analyze the single factor impact on overall survival, Kaplan-Meier analysis was used to describe survival curve, and Cox proportional hazard model was used for multivariate analysis.
 Results: The immunoreactive scores for Sorcin in chemoresistant ovarian cancer tissues were higher than those in the sensitive ovarian cancer tissues (P<0.001). The levels of Sorcin inovarian cancer tissue did not show statistical significance with different ages, tumor stages, classifications, tissue types, degrees of ascites, omentums, and tumor metastases (P>0.05). The correlation between Sorcin and overall survival in resistant and sensitive ovarian cancer groups was not statistically significant (P>0.05), while there was a negative correlation between the expression of Sorcin and the overall survival of total cases (r=-0.326, P<0.05). Log-rank test showed that the drug resistance factor had a distinct impact on overall survival (P<0.001), and the Sorcin expression had an impact on overall survival (P<0.05). However, correlation between overall survival and the ages, ascites, omentum carcinoma, pathological types, pathological grade or FIGO staging was not significant (P>0.05). Cox proportional hazard model showed that drug resistance had a significant effect on overall survival (P<0.001), with a relative risk at 8.635, and the survival curve of the ovarian cancer sensitive group was obviously superior to that of ovarian cancer drug resistance group.
 Conclusion: Sorcin may be associated with drug resistance in ovarian cancer. The expression of Sorcin is correlated with the overall survival. The lower the Sorcin expression, the longer the survival time. Chemoresistance may act as an important independent prognostic factor for the poor prognosis for ovarian cancer.
