Objective To investigate the application value of single or combined detection of HE4 and CA125 in the differentia‐tion diagnosis of endometriosis .Methods The detection results of serum HE4 and CA125 levels in 105 cases of patients with ovari‐an endometriosis (endometriosis group) ,53 cases of patients with (ovarian malignant group) tumor and 64 healthy women undergo‐ing the healthy physical examination(control group) were performed the retrospective and statistical analysis .Results The positive rates of serum HE4 in the endometriosis group ,ovarian malignant tumor group and control group were 57 .1% ,90 .6% and 12 .5%respectively with statistically significant difference among them (P< 0 .05) .The positive rates of serum CA125 in the above 3 groups were 44 .8% ,92 .5% and 14 .0% respectively ,and the differences were statistically significant(P<0 .05) .(3)The sensitivity and specificity of 70 pmol/L≤ HE4<150 pmol/L for diagnosing endometriosis were 57 .14% and 53 .86% respectively ,which of 35 U/mL≤CA125<150 U/mL for diagnosing endometriosis were 44 .76% and 61 .24% .But the sensitivity and specificity of their combined detection were 70 .32% and 60 .38% .There were statistically significant differences of sensitivity and specificity among single and combined detecion of HE4 and CA125(P<0 .05) .Conclusion Serum HE4 and CA125 levels are significantly elevated in the patients with endometriosis ,their combined detection could further raise the sensitivity for diagnosing endometriosis .

Objective To study the difference of attentional bias towards general negative words between non-mediated obsessive-compulsive disorder (OCD) patients and healthy controls.Methods Event-related potentials (ERPs) were collected from 26 non-mediated OCD patients and 24 normal controls while they performed an emotional Stroop task.Results Compared to healthy controls,OCD patients showed significantly longer reaction time (OCD:(467 ± 14.88) ms,Controls:(409.65 ± 15.49) ms,P＜ 0.01),and had significantly larger P2 and P3 amplitude to all three types of words (P2 amplitude:OCD:(10.41±0.49) μV,Controls:(8.89±0.48) μV,P＜0.05;P3 amplitude:(10.04±0.68) μV,Controls:(7.68±0.67) μV,P＜0.05).In addition,the P2 peak latency of the frontal area in OCD patients was significantly longer than that in healthy controls(OCD:(190.09±4.71) ms,Controls:(179.60±4.72) ms,P＜0.05).Conclusion Current findings suggest that OCD patients are characterized by a general attentional inhibition deficit but not an attentional bias to the negative words.

Objective To compare genomic copy number variations (CNVs) among different subtypes of breast cancer and analyze specific CNVs in each subtype. Methods AIMS software was used for genotype breast cancer (BasL, Her2, LumA and LumB), and GISTIC2.0 software was used to analyze genome-wide CNVs in tumor tissues from TCGA. We collected and analyzed the information and samples of 324 cases of invasive breast cancer admitted to Jiangmen Central Hospital(JMCH). Fluorescence quantitative PCR was used to detect the CNV of ERBB2, TFDP1, MIR148B, CCND1, MDM2 and MIR139 genes in the tumor tissues, to verify TCGA analysis. Results 13q34 was specifically amplified and 12q13.13 was specifically deleted in BasL-type breast cancer. The 17q12 was specifically amplified in Her2 type. The 12q15 was specifically amplified and 11q13.4 was specifically deleted in LumB type, but LumA type had no specific amplification or deletion of chromosome region. The proportion of TFDP1 amplification or MIR148B deletion in BasL type were 57.8% (TCGA) and 71.4% (JMCH), which were significantly higher than other subtypes (P < 0.001). The proportion of ERBB2 amplification of Her2 type were 55.2% (TCGA) and 86.7% (JMCH), which were significantly higher than other subtypes (P < 0.001). The proportion of LumB type with CCND1 or MDM2 amplification or MIR139 deletion were 47.6% (TCGA) and 61.8% (JMCH), which were significantly higher than other subtypes (P < 0.05). Conclusion At the CNV level of breast cancer, Her2 type is characterized by the amplification of ERBB2, BasL type is characterized by the amplification of TFDP1 or the deletion of MIR148B, LumB type is characterized by the amplification of CCND1 or MDM2 or the deletion of MIR139, but LumA type lacks specific CNV characteristics.

s] Objective To evaluate the effect of comprehensive schistosomiasis control measures with focus on total removal of cattle and sheep in Junshan District,Yueyang City. Methods The retrospective review and field survey were implemented in the pilot villages in Junshan District. The data of Schistosoma japonicum infection status of human,cattle,sheep and Oncome-lania hupensis snails,and density of snails were gathered and modeled in the period of 2006 to 2016. Results The prevalence of schistosome infection in residents in the pilot villages decreased from 3.44％ in 2006 to 0.59％ in 2012(F = 14.501,P =0.013). After removal of all the cattle and sheep in 2013,the prevalence of schistosome infection in the residents decreased to zero in 2016(F=14.148,P=0.033). The density of living snails decreased from 0.8833/0.1 m2 in 2006 to 0.3088/0.1 m2 in 2012(F=76.250,P=0.005). Conclusion The comprehensive schistosomiasis control strategy with focus on cattle and sheep removal is remarkably effective.

Objective:To explore the relationship between death indicators and unplanned return indicators on healthcare quality evaluation.Methods:A total of 836 976 medical record data were collected from 31 tertiary public general hospitals in a diagnosis-related groups(DRG) data platform in 2017. Multiple death indices(low and low-risk risk group mortality, high-risk group mortality, crude mortality, and risk adjusted mortality) and unplanned return indices(31-day unplanned readmission rate and 31-day unplanned return to surgery rate) were calculated. Pearson′s correlation coefficient was used to examine the relationships among those indices.Results:Death indicators were correlated with each other, but the unplanned readmission rate was not correlated with the unplanned reoperation rate( r=0.305). There was no correlation between unplanned re-entry rate and death rate. The correlation coefficients were as follows: unplanned readmission rate versus low and low-risk group mortality( r=-0.227), versus high-risk group mortality( r=-0.098), versus actual mortality( r=-0.130), versus risk adjusted mortality( r=0.010); unplanned reoperation rate versus low and low-risk group mortality( r=0.105), versus high-risk group mortality( r=0.030), versus actual mortality( r=-0.004), versus risk adjusted mortality( r=-0.141). Conclusions:The indicators of death and the indicators of unplanned return are not the same in terms of actual management technology and evaluation effect. They are complementary to each other and can form an ideal combination of quality evaluation indicators.

Objective:To explore the influencing factors of 31-day unplanned readmission in obstetrics.Methods:The medical records and relevant clinical data of 29 public hospitals in a province in 2017 were collected to construct a two-level logistic regression model on the influencing factors of 31-day unplanned readmission.Results:In 2017, there were 71 330 obstetric patients discharged from 29 public hospitals, 690 of whom were unplanned readmitted in 31 days, accounting for 0.97%. The type of medical insurance payment, number of previous hospitalization, condition of previous hospitalization, age, history of cesarean section, pregnancy complications and complications during delivery were all the factors influencing the 31-day unplanned readmission of obstetrics.Conclusions:The condition of 31-day unplanned readmission could be influenced by the factors of sociology, previous visit and clinical. These factors should be considered reasonably in the evaluation and management of obstetric quality.

Objective:To understand the epidemiological and clinical characteristics of melioidosis in Haikou City, to rise the people's awareness of melioidosis and to provide basis for prevention and control of the disease.Methods:The clinical data of 254 patients with melioidosis treated in 4 Class A tertiary hospitals in Haikou City from January 2000 to September 2020 were collected, and the epidemiological characteristics, clinical manifestations, infection site, prognosis and drug sensitivity were retrospectively analyzed.Results:Among 254 patients with melioidosis, 226 males (88.98%) and 28 females (11.02%), and the gender ratio was 8.07 ∶ 1.00. Farmers were the main occupation, accounting for 37.80% (96/254). The median age was 53 years old, mainly in 41 - 80 years old, accounting for 83.46% (212/254). Han nationality was the most, accounting for 89.76% (228/254). The onset season was mainly in summer and autumn, and the peak was from August to October (117 cases).

The incidence peak is in summer and autumn. The common clinical manifestations are fever, pulmonary infection, abscess of liver and spleen, etc. In the treatment, Burkholderia pseudomallei is more sensitive to imipenem, meropenem and ceftazidime.

ObjectiveTo explore the research hotspots and development trends in the field of autism spectrum disorder (ASD) in the past ten years, the literatures of microglia-related neuroinflammation of ASD and the immune regulation and possible pathways of exercise ameliorating ASD symptoms were reviewed. MethodsArticles about microglia-related research in ASD during January, 2012 to December, 2021 were searched in the core collection database of Web of Science. The CiteSpace 5.8.R3 software was used to summarize the main findings, visualize and analyze the annual publication volume, high-frequency keywords and keyword clustering. Results and ConclusionA total of 783 papers were returned. The numbers of papers published increased with time. The neuroinflammation was a research hotspot in the pathogenesis of ASD, among which abnormal activation of microglia and the levels of inflammatory cytokines were important factors in the occurrence and development of ASD. Exercise was an important intervention to improve symptoms of ASD, which may associate with reducing neuroinflammation or regulating microglia-mediated inflammatory pathways.
