Objective: To investigate the prevalence of hyperactivity behavior in children aged 3-6 in Yunnan Province, to explore its relationship with neuropsychological development, so as to provide clues for early prevention and intervention of attention deficit hyperactivity disorder (ADHD) in children. Methods: A total of 1 321 children aged 3 to 6 from 10 kindergartens in 5 prefectures (cities) of Yunnan Province were selected by stratified random sampling method from October 2022 to May 2023. Teacher Rating Scale (TRS) was used to investigate childrens hyperactive behavior and coexistent behavior. A qualified evaluator applied the Developmental Scale for Children Aged 0-6 Years to assess the development of 5 ability areas of gross motor movement，fine movement，adaptive ability，language and social behavior. Statistical analysis was performed using Wilcoxon rank sum test and χ2 test. Binary Logistic regression was applied to analyze the score of their hyperactivity behavior and its relationship with other behavior problems and neuropsychological development. Results: The detection rate of hyperactivity behavior was 8.6% in children aged 3 to 6 years, 12.8% in boys and 4.1% in girls (χ2=31.53, P<0.01). The detection rate of hyperactivity in 3yearold children was 13.9%, which was higher than that in 4yearold (9.2%) and 5yearold children (7.0%) (χ2=8.73, P<0.05). The detection rate of inattentionpassivity of rural children (14.6%) was higher than that of urban children (5.9%) (χ2=22.23, P<0.01). Binary Logistic regression analysis showed that the higher the level of adaptive development, the lower the risk of hyperactivity (OR=0.58, 95%CI=0.39-0.86), the higher the risk of hyperactivity (OR=0.57, 95%CI=0.35-0.91), the higher the risk of conduct problems (OR=0.57, 95%CI=0.37-0.87), inattentionpassivity (OR=0.49, 95%CI=0.33-0.74) were also at lower risk (P<0.05). Children with higher levels of fine motor development had a lower risk of inattentionpassivity (OR=0.59, 95%CI=0.37-0.93, P<0.05). Conclusions Hyperactivity in boys and inattentionpassivity in rural children requires more attention. It is necessary to strengthen childrens early adaptive ability and fine motor training to prevent hyperactive behavior and inattention.

Objective To provide data base for the development of X-ray computed tomography (CT) diagnostic reference levels suitable for the physical characteristics of residents in Qingdao City, China. Methods A total of 3351 cases of adult CT scan data derived from 14 devices were randomly selected from three tertiary hospitals and one primary hospital from January 1 to December 31, 2022. CT examination was performed on the brain, paranasal sinus, neck, chest, abdomen, cervical vertebrae, and lumbar vertebrae. The cases also included CT angiography (CTA) data on the brain, neck artery, pulmonary artery, and aorta. The data types included tube voltage (kV), effective tube current (mAs), computed tomography dose index volume (CTDI_vol), and dose length product (DLP). The 1st, 2nd, 3rd quartile values of CTDI_vol and DLP were calculated. Results Large differences were observed in DLP among different body parts of adults. The DLP value showed a descending order of craniocerebral CTA, craniocerebral CT, abdomen CT, lumbar vertebral spiral CT, aorta CTA, pulmonary artery CTA, paranasal sinus CT, chest CT, cervical vertebral spiral CT, and neck CT. The 3rd quartile DLP values of the brain and neck were 657.9 and 228.1 mGy·cm, respectively. The CTDI_vol of the brain was largest (3rd quartile, 52.0 mGy) and the CTDI_vol of the chest was smallest (3rd quartile, 8.2 mGy). Conclusion There are significant differences in CTDI_vol and DLP between different body parts of adults in Qingdao City, and CT radiation dose levels are relatively low compared to other regions in China and other countries.

Objective:To describe the epidemiological distribution of hemorrhoids in a physical exami-nation population in China,which could provide evidence for precision prevention and early intervention of hemorrhoids.Methods:Chinese subjects over 18 years of age who underwent a physical examination in a nationwide chain of physical examination centers in 2018 were studied in a cross-sectional design,which collected information by a questionnaire and physical examination results from each subject.The epidemiological distribution of hemorrhoids was described using Logistic models.The gender-,age-,and region-detection rates of hemorrhoids were standardized to the Sixth National Population Census of the People's Republic of China(2010).Results:A total of 2 940 295 adult subjects were included in the study,of whom the average age was(41.7±14.0)years,and 52.6％were females.The standardized detection rate of hemorrhoids was higher for females(43.7％)than that for males(17.7％;P＜0.001)in this study.In the females,the age distribution of hemorrhoids was inverted U-shaped,with the highest standardized detection rate of hemorrhoids in the age group of 30-39 years(63.5％).In the males,the standardized detection rate of hemorrhoids increased along with age,with the highest percentage of 17.2％in the age group of 50-59 years,and the standardized detection rate of hemorrhoids in the age group of 60 and above decreased slightly(P＜0.001 for trend test).The participants with hypertension had a higher standardized detection rate of hemorrhoids than those with normal blood pressure in both males and females(P＜0.001).The standardized detection rate of hemorrhoids showed a positive corre-lation with body mass index(P＜0.001 for trend test in males).Conclusion:The detection rate of hemorrhoids varied to gender,age,obesity,and hypertension status,which could help to identify the risk factors and the high-risk sub-groups,and hence to strengthen health education and early detection accordingly,which could eventually reduce the incidence of hemorrhoids and improve the quality of life and health in the Chinese population.This study was conducted in a physical examination population,and the conclusions of this study should be extrapolated with caution.

Objective:To explore the significance of triggering receptor expressed on myeloid cells-2 (TREM-2) prognostic evaluation so as to provide novel biological markers in clinical practice for patients with hepatitis B virus-related acute-on-chronic liver failure ( HBV-ACLF).Methods:The research subjects of this study were divided into an experimental group and a control group. Fifty HBV-ACLF cases admitted to the Department of Infectious Diseases of the First Affiliated Hospital of Nanchang University from January 1, 2019 to December 31, 2019 were selected as the experimental group. Patients were divided into survival and death groups according to the actual prognosis at discharge (self-discharge and dead patients were considered death groups, and all enrolled patients were hospitalized for more than 28 days). Twenty-five healthy subjects were chosen as the control group. Peripheral venous blood was collected from the experimental group and the control group. Plasma and peripheral blood mononuclear cells (PBMC) were isolated. The concentrations of TREM-2, interleukin (IL)-6, and IL-8 were detected in the plasma. TREM-2 mRNA expression was detected in PBMC. A single blood sample was collected from the control group, whereas five blood samples were dynamically collected from the experimental group on the day of admittance and at 7, 14, 21, and 28 days after treatment commenced. Simultaneously, upon admission, the relevant clinical indicators of HBV-ACLF patients were monitored, including the liver function test: alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, coagulation function test: international normalized ratio, prothrombin time, and other indicators. Measurement data were expressed as mean±standard deviation (x±s). Count data were compared and analyzed using the χ 2 test. The intra-group factor mean was compared using a repeated measures ANOVA. The means were analyzed by t-tests between the two groups. Bivariate correlation analysis was used to analyze the correlation between the two variables. The value of TREM-2 as a diagnostic marker was analyzed using the receiver operating characteristic (ROC) curve. Results:The mRNA expression of TREM-2 in the PBMC of HBV-ACLF patients showed a gradually increasing trend at various time points and was significantly higher in the survival group than that of the control group at 28 days ( P < 0.01), while the death group showed a gradually weakening trend at various time points and was significantly lower than the control group at 28 days ( P < 0.01). (1) The levels of TREM-2 in the plasma of HBV-ACLF patients generally showed a gradually increasing trend at various time points in the survival group. The levels on the day of admission and 7, 14, 21, and 28 days after the initiation of treatment were (1.49±0.85), (1.62±0.58), (1.95±0.69), (2.33±0.71), and (2.00±0.67) ng/ml, respectively. The expression of TREM-2 in the death group showed a gradually weakening trend at various time points. The levels on the day of admission and 7, 14, 21, and 28 days after initiation of treatment were (1.40±0.73), (1.59±0.79), (1.56±0.80), (1.05±0.49), and (0.81±0.21) ng/ml, respectively. The survival group's various detection time points were higher than those of the death group, and the difference was statistically significant. The plasma level of TREM-2 in the healthy control group was (1.25±0.35) ng/ml. (2) The concentrations of IL-6 and IL-8 in the plasma of HBV-ACLF patients showed a gradually decreasing trend at various time points in the survival group. The levels on the day of admission and 7, 14, 21, and 28 days after initiation of treatment were (46.70±26.31), (33.98±20.28), (19.07±10.24), (14.76±7.84), (9.12±7.65) and (108.29±47.07), (93.85±26.53), (79.27±34.63), (56.72 ±18.30), (37.81±13.88) pg/ml, respectively. However, its concentration in the death group fluctuated within a relatively high range. The levels on the day of admission and 7, 14, 21, and 28 days after the initiation of treatment were (41.94±24.19), (36.99±19.78), (34.30±20.62), (34.14±14.52), (36.64±23.61) and (104.65±50.16), (112.98±45.03), (118.43±45.00), (111.67±40.44), (109.55±27.54) pg/ml, respectively. (3) Bivariate correlation analysis results indicated that the plasma TREM-2 content was negatively correlated with the plasma levels of pro-inflammatory cytokines IL-6 and IL-8 ( r = -0.224, P = 0.025; r = - 0.223, P = 0.026). ROC curve analysis showed that the mRNA levels of TREM-2 in PBMCs at various time points for prognostic evaluation of HBV-ACLF patients were 1d=0.667, 7d=0.757, 14d=0.979, 21d=0.986, and 28d= 0.993. The areas under the ROC curve of the TREM-2 content in the plasma at various time points were 1d=0.522, 7d=0.571, 14d=0.658, 21d=0.927, and 28d=0.994. Conclusion:TREM-2 mRNA expression in PBMC and TREM-2 content in plasma have a significant relationship to the prognosis of HBV-ACLF patients and may inhibit the liver inflammatory response by regulating the secretion of pro-inflammatory cytokines IL-6 and IL-8. Dynamic monitoring of TREM-2 expression in peripheral blood is favorable for evaluating the prognostic condition of HBV-ACLF patients.

Objective To evaluate the clinical efficacy of comprehensive treatment for synchronous primary advanced gastric and esophageal cancer by propensity score matching(PSM).Methods A total of 2 551 patients with advanced gastric cancer admitted to Jiangsu Province Hospital of Chinese Medicine from January 2013 to December 2022 were retrospectively analyzed.Among them,45 patients with synchronous primary esophageal cancer were distributed to the observation group,and 2 506 patients without esophageal cancer were distributed to the control group.Through the PSM method,the control group was matched with the observation group and the equilibrium samples of covariates between two groups were obtained.The overall survival(OS)between the two groups were compared.Results Both observation and control group contained 45 patients in this study.According to the treatment regimen,the patients in the observation group was divided into radical resection treatment subgroup(n=22)and chemoradiotherapy(CRT)subgroup(n=23).In the radical resection subgroup,4 patients underwent the simultaneous surgical resection of gastric and esophageal tumors through proximal gastrectomy with the Ivor Lewis operation.Eighteen patients underwent endoscopic submucosal dissection(ESD)of their esophageal tumors and gastric cancer radical resection.Radical resection of gastric cancer combined with preoperative chemoradiotherapy of esophageal cancer was performed in the CRT subgroup.Survival analysis showed that OS in the observation group was significantly shorter than that in the control group(P=0.042)and there was no significant difference in OS between the radical resection subgroup and the control group(P=0.799).The 1-,3-,and 5-year survival rates of the patients in the CRT subgroup were significantly lower than those of the control group(P=0.003).While the 1-,3-,and 5-year survival rates of the patients in the radical resection subgroup were not statistically significant,compared to those of the CRT subgroup(P=0.071).Conclusions Multidisciplinary and comprehensive treatment can significantly improve the prognosis of patients with synchronous primary advanced gastric and esophageal cancer.Radical resection of gastric cancer combined with ESD of esophageal cancer is an optional treatment for patients with gastric cancer complicated with early esophageal cancer.Radical resection of gastric cancer combined with CRT of esophageal cancer can improve the prognosis of patients with advanced gastric cancer complicated with unresectable esophageal cancer.

Objective To investigate the difference in the prognosis of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) caused by hepatitis recurrence after withdrawal of nucleos(t)ide analogues (NUC) and possible causes in HBeAg-positive versus HBeAg-negative chronic hepatitis B (CHB) patients. Methods A total of 108 CHB patients with HBV-ACLF caused by withdrawal of NUC who were admitted to The First Affiliated Hospital of Nanchang University from January 2017 to December 2018 were enrolled, and according to HBeAg status, these patients were divided into HBeAg-positive group with 57 patients and HBeAg-negative group with 51 patients. The two groups were compared in terms of sex, age, clinical manifestation, signs, levels of total bilirubin, direct bilirubin, alanine aminotransferase, aspartate aminotransferase, prothrombin time, activated partial thromboplastin time, prothrombin time/international normalized ratio, and HBV DNA quantification on admission, complications (including hepatic encephalopathy, hepatorenal syndrome, and spontaneous bacterial peritonitis), and prognosis of HBV-ACLF. In addition, 48 CHB patients with continuous NUC antiviral therapy for > 2 years and HBV DNA < 20 IU/mL were enrolled, and the serum level of HBV pgRNA was measured to investigate the possible causes of the difference in the prognosis of HBV-ACLF between the patients with different HBeAg statuses. The two-independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data. Results For the 108 patients with HBV-ACLF caused by drug withdrawal and recurrence, the HBeAg-positive group had an improvement rate of 49.1% and the HBeAg-negative group had an improvement rate of 74.5%. The HBeAg-negative group had a significantly higher improvement rate than the HBeAg-positive group ( χ 2 =2.811, P =0.006). The HBeAg-positive group had a significantly higher level of HBV DNA than the HBeAg-negative group on admission ( t =-3.138, P =0.002). For the 48 CHB patients who achieved virologic response after long-term antiviral therapy, the HBeAg-positive group had a significantly higher HBV pgRNA load than the HBeAg-negative group ( H =2.814, P =0.049). Conclusion Compared with the HBeAg-positive CHB patients, HBeAg-negative CHB patients have a significantly better improvement rate of HBV-ACLF caused by hepatitis recurrence after withdrawal of NUC antiviral therapy. The difference in baseline HBV pgRNA level may be associated with the difference in the prognosis of HBV-ACLF in patients with different HBeAg statuses.

Background/Aims: Acute-on-chronic liver failure (ACLF) is a catastrophic illness. Few studies investigated the prognostic value of vitamin D-binding protein (VDBP) for hepatitis B virus (HBV)-related ACLF (HBV-ACLF) resulted in conflicting results. Methods: Two prospective HBV-ACLF cohorts (n=287 and n=119) were enrolled to assess and validate the prognostic performance of VDBP. Results: VDBP levels in the non-survivors were significantly lower than in the survivors (P<0.001). Multivariate Cox regression demonstrated that VDBP was an independent prognostic factor for HBV-ACLF. The VDBP level at admission gradually decreased as the number of failed organs increased (P<0.001), and it was closely related to coagulation failure. The areas under the receiver operating characteristic curve (AUCs) of the Child-Pugh-VDBP and chronic liver failuresequential organ failure assessment (CLIF–SOFA)-VDBP scores were significantly higher than those of Child-Pugh (P<0.001) and CLIF-SOFA (P=0.0013). The AUCs of model for end-stage liver disease (MELD)-VDBP were significantly higher than those of MELD (P= 0.0384) only in the case of cirrhotic HBV-ACLF patients. Similar results were validated using an external multicenter HBV-ACLF cohort. By longitudinal observation, the VDBP levels gradually increased in survivors (P=0.026) and gradually decreased in non-survivors (P<0.001). Additionally, the VDBP levels were found to be significantly decreased in the deterioration group (P=0.012) and tended to be decreased in the fluctuation group (P=0.055). In contrast, they showed a significant increase in the improvement group (P=0.036). Conclusions The VDBP was a promising prognostic biomarker for HBV-ACLF. Sequential measurement of circulating VDBP shows value for the monitoring of ACLF progression.

Objective:To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China.Methods:Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women′s socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis.Results:A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95% CI: 4.5%－6.1%) and 13.1% (95% CI: 11.3%－14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions:In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

Objective: To investigate the expression and distribution of sclerostin in the alveolar bone of rat in the absence of estrogen, and to provide evidence for the analysis of the histological correlation between sclerostin and alveolar bone remodeling in rats. Methods : The experimental subjects of this study were 32 8-week-old female Wistar rats. Among them, 16 rats were ovariectomized (OVX), and 16 rats were subjected to a sham operation (Sham). These rats were sacrificed 1, 2, 3, and 4 weeks after the operation, and the mandibles were removed and embedded. The mesial and distal sections of the rat,s mandibular first molars were selected and stained with anti-tartrate phosphatase (TRAP), sclerostin immunostaining, multiple immunostainings, RANKL and TRAP double staining, and silver-plated multiple staining. Results : As the postoperative time in rats increased, the TRAP-positive osteoclasts counts in the OVX group in the interalveolar septum of mandibular first molar increased significantly, and statistical difference was noted between the groups (P ＜ 0.05). The OVX 2w, 3w, and 4w groups exhibited more TRAP-positive osteoclasts compared with the Sham group at the corresponding time point, and the results were statistically different (P ＜ 0.05). Sclerostin immunostaining revealed that the proportion of positive bone cells in the mesial side of the periodontal ligament area of mandibular first molar in the OVX group gradually decreased. Statistical differences were noted between the OVX 3w group and the OVX 4w group as well as the OVX 1w group and, the OVX 2w group (P ＜ 0.05). In the comparison between the area near the periodontal ligament and the central area of the alveolar bone septum of the mandibular first molar in the same group, the positive expression ratio of sclerostin in the OVX 3w and OVX 4w groups in the area near the periodontal ligament was reduced compared with that in the central area of the alveolar bone septum. The results were statistically significant (P ＜ 0.05). A larger number of osteoblasts was noted around the osteoclasts in the OVX 4w group compared with the Sham 4w group based on ALP/ TRAP /sclerostin multiple staining, whereas less sclerostin-positive osteoblasts were noted in the OVX 4w group. Sclerostin/TRAP/silver plating staining showed that the bone tubules around the sclerostin positive bone cells mostly exhibited a parallel and neat arrangement, and the bone tubules around sclerostin negative bone cells were more irregular and disorderly arranged in the OVX 4w group Conclusion Sclerostin protein is involved in alveolar bone remodeling in estrogen-deficient rats.

OBJECTIVETo explore the feasibility of short-term neoadjuvant chemotherapy (NACT) in patients with advanced gastric cancer (AGC), and to compare clinical efficacy of short-term neoadjuvant chemotherapy with different ways.

METHODSClinical data of 310 AGC patients treated with one course of NACT using EOF regimen(epirubicin, oxaliplatin and fluorouracil plus calcium folinate) in our hospital from January 2008 to December 2011 were retrospectively analyzes. Efficacy was compared between regional arterial infusion chemotherapy and intravenously chemotherapy.

RESULTSAll the 310 AGC patients completed one course of NACT and none was interrupted by adverse events. Postoperative pathological remission rate was 33.9% (105/310) and 5 patients (1.6%) had complete pathological remission. The pathologic response rate in the regional arterial infusion chemotherapy group was higher than that in the intravenously chemotherapy group(42.4% vs. 23.6%, P = 0.001). Multivariate analysis revealed that chemotherapy method(HR=1.827, 95% CI:1.006-3.316, P = 0.048) was associated with significantly higher pathologic response.

CONCLUSIONSPathological response rate is quite low following short-term NACT. Regional arterial infusion chemotherapy with short-term NACT can improve the pathological response rate of advanced gastric cancer.
