Objective To observe the changes of the depressive behavior and amygdaloid nucleus nerve growth factor(NGF)expression in estro?gen?deprived female rats and explore the possible mechanism and targets of estradiol in depression treatment. Methods A total of 30 adult SD fe?male rats were randomly assigned to 3 groups:sham operation group(SHAM,n=10);ovariectomized group(OVX,n=10)and ovariectomized rats treated with estradiol group(OVX+E,n=10). The behavior changes were observed by tail suspension test(TST)and sucrose preference test (SPT) after 8?week estradiol treatment. Subsequently ,immunohistochemical staining detect NGF expression in amygdaloid nucleus. Results Compared with the SHAM group rats,sucrose preference ratio significantly decreased in SPT(P<0.01),immobile time prolonged in TST(P<0.01),serum estradiol level and amygdaloid NGF expression significantly decreased(all P<0.01). 8?week estradiol treatment ameliorated depres?sion?like behavior and increased serum E2 level and NGF expression in amygdaloid nucleus in OVX+E group rats when compared with the OVX group(all P<0.01). Conclusion Estradiol treatment can improve the depressive behavior of ovariectomized rats ,which may be related to the in?crease of serum estradiol level and the expression of NGF in amygdaloid nucleus.

The influenza virus has evolved numerous mechanisms to overcome host defenses for its benefit. It can also manipulate the immune system to stop it monitoring and clearing the virus. Small ubiquitin-like modifier (SUMO)ylation is emerging as a key post-translational modification that plays an important part in virus replication. This brief review focuses on recent findings on the roles of SUMOylation during infection by the influenza virus. As such, it will aid understanding of the mechanism of action of infection by the influenza virus, and help to provide new strategies for anti-viral treatment.

OBJECTIVETo examine the prevalence of obesity phenotypes and cardiometablic disorders (CDs) among children aged 6- 17 in Beijing from 2004 to 2013.
METHODSData were obtained from two cross-section surveys, which were conducted in 2004 and 2013. In 2004, by using stratified cluster sampling design, 20 primary or middle schools were selected from 7 districts (Xicheng, Dongcheng, Chaoyang, Haidian, Daxing, Pinggu, and Yanqing) in Beijing, and 20 554 school children aged 6-17 were recruited, with weight, height, waist circumference and blood pressure measured. Fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were measured in 962 subjects from one school. In 2013, by using the same sampling design, 7 211 students from two districts (Haidian and Dongcheng) were surveyed with weight, height, waist circumference and blood pressure measured, and fasting plasma glucose and lipid profile (TC, TG, HDL-C, LDL-C) were measured for 1 344 subjects in the same school measured in 2004. Student's-t test was used to analyze the difference in body mass index(BMI), WC, and waist to height ratio (WHtR) among children between 2004 and 2010. Chi-square test was used to analyze the difference of hypertension, impaired fasting glucose(IFG), dyslipidemia, and metabolic disorders clustering between 2004 and 2010, and among different types of obesity; logistic regression model was used to analyze the association between three types of obesity and risks of cardiovascular metabolic disorders.
RESULTSIn boys, BMI ((20.3 ± 4.4) vs (19.4 ± 4.2) kg/m(2), t=11.18, P<0.001), WC ((70.6 ± 12.8) vs (66.7 ± 11.8) cm, t=17.20, P<0.001) and WHtR (0.451 ± 0.064 vs 0.437 ± 0.059, t=11.64, P<0.001) were significantly higher in 2013 than those in 2004. Similarly in girls, BMI ((18.9 ± 3.6) vs (18.7 ± 3.7) kg/m(2), t=12.21, P<0.001), WC ((64.5 ± 9.6) vs (63.0 ± 9.3) cm, t=8.15, P<0.001) and WHtR (0.430 ± 0.047 vs 0.423 ± 0.047, t=14.13, P<0.001) were also significantly higher in 2013 than those in 2004. The prevalence of combined obesity rose from 8.27% (1 697/20 526) in 2004 to 10.74% (774/7 209) in 2013, and central obesity from 3.08% (632/20 526) to 4.44% (320/7 209). The prevalence of hypertension (10.78%(313/1 344) vs 4.29% (42/962), χ(2)=36.76, P<0.001), IFG(49.54%(664/1 344) vs 6.45%(63/962), χ(2)=506.61, P<0.001), high TC(11.53%(155/1 344) vs 5.03%(49/962), χ(2)=28.31, P< 0.001), high TG(7.51%(101/1 344) vs 3.59%(35/962), χ(2)=29.59, P<0.001) were significantly higher in 2013 than those in 2004. Subjects with combined obesity had higher risks of hypertension (OR=5.88, 95% CI: 4.42-7.82), high TG (OR=7.12, 95%CI: 4.35-11.64), low HDL-C (OR=3.04, 95%CI: 1.55-5.95), high LDL-C (OR=2.27, 95% CI: 1.22-4.02), CDs≥2 (OR=3.07, 95% CI: 2.09-4.50), comparing to children without obesity.
CONCLUSIONThe prevalence of types of obesity and obesity-related metabolic disorders, except for low HDL-C and high HDL-C, were significantly higher in 2013 than those 2004 among chlildren aged 6-17 year in Beijing. Children with combined obesity had higher prevalence of metabolic disorders.

Purpose:
SOX12 is overexpressed in many cancers, and we aimed to explore the biological function and mechanism of SOX12 in thyroid cancer.
Materials and Methods:
We first analyzed the expression of SOX12 in thyroid cancer using data in The Cancer Genome Atlas. Immunohistochemistry and qRT-PCR were performed to identify SOX12 expression in thyroid cancer tissue and cells. Thyroid cancer cells were transfected with small interfering RNA targeting SOX12, and cellular functional experiments, including CCK8, wound healing, and Transwell assays, were performed. Protein expression was examined by Western blot analysis. A xenograft model was developed to evaluate the effect of SOX12 on tumor growth in vivo.
Results:
SOX12 expression was increased in thyroid cancer tissue and cells. SOX12 promoted cell proliferation, migration, and invasion and accelerated tumor growth in vivo. The expression of PCNA, Cyclin D1, E-cadherin, Snail, MMP-2, and MMP-9 was affected by SOX12 knockdown. Bioinformatic analysis showed that SOX12 could interact with the POU family. SOX12 knockdown inhibited the expression of POU2F1, POU2F2, POU3F1 and POU3F2, and SOX12 expression showed a positive correlation with POU2F1, POU3F1, and POU3F2 expression in clinical data. POU2F1 and POU3F1 were able to reverse the effect of SOX12 knockdown on thyroid cancer cells.
Conclusion
SOX12 affects the progression of thyroid cancer by regulating epithelial-mesenchymal transition and interacting with POU2F1 and POU3F1, which may be novel targets for thyroid cancer molecular therapy.

In recent years, immune checkpoint inhibitors (ICIs) have been widely used in malignant solid tumors with remarkable efficacy. However, in colorectal cancer (CRC), ICIs have shown significant therapeutic effects only in patients with highly microsatellite unstable/mismatch repair-deficient metastatic CRC and these patients are only a minority of all CRC patients. In contrast, the majority of patients, those with microsatellite stable (MSS)/mismatch repair-complete (pMMR)-type metastatic CRC, could hardly benefit from ICI monotherapies, and immune combination therapies have become the key to solveing this clinical challenge. This article introduces the common patterns and possible mechanisms of immune-combination therapies for MSS/pMMR-type CRC, the exploration and progress made in the application of immune-combination therapies, as well as the possible predictive markers of efficacy of immune therapies. The prospects and directions of ICIs in the treatment of MSS/pMMR-type CRC are also discussed.

Objective:To investigate the safety and short-term efficacy of laparoscopic pro-ximal gastrectomy (LPG) for proximal gastric cancer and adenocarcinoma of esophagogastric junction.Methods:The retrospective cohort study was conducted. The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years. Of the 385 patients, 335 cases undergoing LPG were divided into the laparoscopic group and 50 cases undergoing open proximal gastrectomy were divided into the open group. Observation indicators: (1) intraoperative and postoperative situations; (2) follow-up; (3) stratified analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Intraoperative and postoperative situations. The operation time, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, cases with postoperative pathological staging as stage 0?Ⅰ and stage Ⅱ?Ⅲ, duration of postoperative hospital stay, cases with postoperative early complications were (212±96)minutes, 270, 65, 177, 107, 10(range, 8?14)days, 40 in patients of the laparoscopic group, with 51 cases missing the data of postoperative pathological staging. The above indicators were (174±90)minutes, 39, 11, 22, 28, 10(range, 8?18)days, 10 in patients of the open group. There were significant differences in the opera-tion time and postoperative pathological staging between the two groups ( t=2.62, χ2=5.93, P<0.05), and there was no significant difference in the reconstruction of digestive tract, duration of post-operative hospital stay, postoperative early complications between the two groups ( χ2=0.19, Z=0.40, χ2=2.50, P>0.05). (2) Follow-up. Of the 385 patients,202 cases were followed up during the post-operative 12 months, including 187 cases in the laparoscopic group and 15 cases in the open group. Cases with reflux esophagitis, cases with esophageal anastomotic stenosis were 48, 11 in patients of the laparoscopic group, versus 5, 2 in patients of the open group, showing no significant difference in the above indicators between the two groups ( P>0.05). The body mass index (BMI), hemoglobin (Hb), albumin (Alb) at postoperative 6 months and 12 months were (21±3)kg/m 2, (130±15)g/L, (40±4)g/L and (21±3)kg/m 2, (132±14)g/L, (41±4)g/L in patients of the laparoscopic group, versus (21±3)kg/m 2, (121±19)g/L, (37±5)g/L and (21±3)kg/m 2, (125±21)g/L, (43±6)g/L in patients of the open group. There were significant differences in postoperative Hb between the two groups ( Fgroup=5.88, Ftime=5.49, Finteraction=19.95, P<0.05) and there were significant differences in time effect of postopera-tive BMI and Alb between the two groups ( Ftime=9.53, 49.88, P<0.05). (3) Stratified analysis. ① Incidence of postoperative of reflux esophagitis and esophageal anastomotic stenosis in patients with different reconstruction of digestive tract. Of the 202 patients, cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis were 168 and 34, respectively. The incidence rates of postoperative of reflux esophagitis were 26.79%(45/168)and 23.53%(8/34)in cases with reconstruction of digestive tract as esophagogastric anastomosis and esophageal-jejunal anastomosis, showing no significant difference between them ( χ2=0.16, P>0.05). Cases undergoing esophageal anastomotic stenosis were 13 in patients with reconstruction of diges-tive tract as esophagogastric anastomosis. ② The BMI, Hb, Alb in patients with different reconstruc-tion of digestive tract. The BMI, Hb, Alb were (24±3)kg/m 2, (135±20)g/L, (41±5)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis before the operation, versus (23±3)kg/m 2, (130±19)g/L, (40±4)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis before the operation, showing no significant difference between them ( t=1.44, 1.77, 1.33, P>0.05). The BMI, Hb, Alb at postoperative 6 months and 12 months were (21±3)kg/m 2, (128±16)g/L, (39±4)g/L and (21±3)kg/m 2, (131±16)g/L, (41±4)g/L in the 168 patients with reconstruction of digestive tract as esophagogastric anastomosis, versus (20±4)kg/m 2, (133±13)g/L, (43±3)g/L and (21±3)kg/m 2, (135±12)g/L, (44±3)g/L in the 34 patients with reconstruction of digestive tract as esophageal-jejunal anastomosis. There were significant differences in the group effect and time effect of postoperative Alb between patients with different reconstruction of diges-tive tract ( Fgroup=15.82, Ftime=5.43, P<0.05), and there was also a significant difference in the time effect of postoperative BMI between them ( Ftime=4.22 , P<0.05). Conclusion:LPG can be used to the treatment of proximal gastric cancer and adenocarcinoma of esophagogastric junction, with a good safety and short-term efficacy.

With the continuous improvement of medical information and intelligence, multi-modal data fusion technology is increasingly widely used in the medical field. Multi-modal data not only has a large quantity, but also has rich information content, which can provide strong support for clinical nursing decision-making. However, due to the uneven level of informatization and intelligence development among medical institutions, the development and application of nursing decision support system is still in a fragmented state. Based on this, this study explores in depth the current application status and challenges faced by multi-modal data fusion in nursing decision support systems, with the aim of providing reference for the design and improvement of nursing decision support system at all levels of medical institutions in the future.
