ObjectiveTo investigate the mechanism of the modified of Bazhentang combined with Guishentang in improving pregnancy outcomes in mouse models of embryo implantation dysfunction by regulating T helper 1/T helper 2 (Th1/Th2) immune balance. MethodsEighty ICR female mice were randomly divided into four groups (n=20 per group) on gestational day 1 (GD1): control, model, western medicine, and traditional Chinese medicine (TCM) groups. Except for the control group, all mice received mifepristone solution (0.2 mg/mouse) via oral gavage on GD4 to induce embryo implantation dysfunction. The TCM group received a water decoction of the modified of Bazhentang combined with Guishentang (20.8 g·kg-1), with the western medicine group administered dydrogesterone (3.9 mg·kg-1), and the control/model groups given equal volumes of saline. All treatments were administered once daily from GD1 until one day before sample collection. Outcomes included implantation site counts (macroscopic observation), pregnancy rates, body weight, endometrial histopathology (hematoxylin-eosin staining), uterine expression of T-box expressed in T cells (T-bet), GATA-binding protein 3 (GATA3), interferon gamma (IFN-γ), and interleukin-4 (IL-4) at protein (Western blot) and mRNA (real-time polymerase chain reaction, Real-time PCR) levels, serum IFN-γ and IL-4 levels (enzyme-linked immunosorbent assay, ELISA), and Th1/Th2 immune balance evaluated by calculating T-bet/GATA3 and IFN-γ/IL-4 ratios. ResultsCompared to the control group, the model group showed no significant change in pregnancy rate but exhibited a marked reduction in average implantation sites and body weight (P<0.01). Histopathological analysis revealed endometrial abnormalities, including decreased glandular density, stromal compaction, and absence of nucleolar vacuoles. At the molecular level, uterine tissue in the model group demonstrated significantly upregulated expression of T-bet and IFN-γ (P<0.05, P<0.01), alongside markedly downregulated GATA3 and IL-4 expression (P<0.05, P<0.01). Serum analysis confirmed markedly elevated IFN-γ (P<0.01) and reduced IL-4 levels (P<0.01), resulting in significantly increased T-bet/GATA3 and IFN-γ/IL-4 ratios (P<0.01). Compared to the model group, pregnancy rates in all treatment groups showed no significant change. Implantation sites and body weight increased substantially (P<0.01), with restored endometrial morphology characterized by enhanced glandular density, stromal edema, and reappearance of nucleolar vacuoles. Significant downregulation of T-bet and IFN-γ (P<0.01) and upregulation of GATA3 and IL-4 (P<0.05, P<0.01) in uterine tissue were observed. Serum IFN-γ levels were significantly reduced (P<0.05, P<0.01), while IL-4 levels were significantly elevated (P<0.05). The Th1/Th2 ratios were significantly decreased (P<0.01). ConclusionThe modified of Bazhentang combined with Guishentang significantly enhances the number of embryo implantation sites in mice with embryo implantation dysfunction, potentially through modulating T-bet/GATA3 expression, restoring Th1/Th2 immune balance, and improving endometrial receptivity.

Chinese Journal of School Health 2025;46(9):1232-1236
Objective:
To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion.
Methods:
Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents.
Results:
In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14),and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05).
Conclusions
The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

Objective: To explore the mechanism by which icariin alleviates viral myocarditis. Methods: CVB3-induced cardiomyocytes were used as an in vitro model of viral myocarditis to assess the effects of icariin treatment on cell viability, inflammation, and apoptosis. Moreover, the effects of icariin on ferroptosis and TLR4 signaling were assessed. After AC16 cells were transfected with TLR4 overexpression plasmids, the role of TLR4 in mediating the regulatory effect of icariin in viral myocarditis was investigated. Results: Icariin significantly elevated cell viability and reduced inflammatory factors TNF-α, IL-1β, IL-6, and IL-18. Flow cytometry revealed that icariin decreased apoptosis rate, and the protein expression of Bax and cleaved caspase 3 and 9 in CVB3-induced cardiomyocytes. Additionally, it suppressed ferroptosis including lipid peroxidation and ferrous ion, as well as the TLR4 signaling. However, TLR4 overexpression abrogated the modulatory effects of icariin. Conclusions: Icariin mitigates CVB3-induced myocardial injury by inhibiting TLR4-mediated ferroptosis. Further animal study is needed to verify its efficacy.

BACKGROUND:Exercise training can improve osteoporosis,but its effects and mechanisms on senile osteoporosis are not fully understood. OBJECTIVE:To observe the effect of treadmill exercise on osteoporosis and wnt/β-catenin signal pathway in aged rats. METHODS:Sixteen 24-month-old male Sprague-Dawley rats were randomly divided into osteoporosis group(n=8)and treadmill group(n=8)and eight 6-month-old male Sprague-Dawley rats were used as young control group.The model of senile osteoporosis was replicated by natural aging and the rats in the treadmill group were treated with treadmill exercise once a day,5 days a week,for 8 weeks.Levels of bone metabolic markers such as type I collagen cross-linked C-terminal peptide,tartrate resistant acid phosphatase,osteocalcin and bone specific alkaline phosphatase were detected by ELISA;bone mineral density of the left femur and L5 was measured by dual energy X-ray;bone scanning and bone microstructure quantitative analysis were performed by bone micro-CT;and the mRNA and protein expression levels of wnt3a,β-catenin,LRP5,DKK1 and GSK3β were detected by RT-PCR and western blot,respectively. RESULTS AND CONCLUSION:Compared with the young control group,the osteoporosis group showed a reduction in serum bone specific alkaline phosphatase and osteocalcin levels(P<0.05),bone mineral density of the femur and L5,the number of tibia and L4 bone trabeculae,bone volume,bone volume fraction(P<0.05),and mRNA and protein expression of wnt3a,β-catenin,and LRP5 in bone marrow tissue(P<0.05)as well as an increase in serum levels of tartrate resistant acid phosphatase and type I collagen cross-linked C-terminal peptide(P<0.05),the intertrabecular space between the tibia and L4,structural model index(P<0.05),and mRNA and protein expression of DKK1 and GSK3 β in bone marrow tissue(P<0.05).In addition to the reduced number of trabeculae in the tibia and L4 vertebrae,the trabeculae were structurally disturbed and sparsely aligned and fractured.Compared with the osteoporosis group,the treadmill group showed an increase in serum bone specific alkaline phosphatase and osteocalcin levels(P<0.05),bone mineral density of the femur and L5(P<0.05),the number of tibial trabeculae,bone volume,bone volume fraction(P<0.05),mRNA and protein expression of wnt3a,β-catenin,and LRP5 in bone marrow tissue(P<0.05)but a reduction in the serum levels of tartrate resistant acid phosphatase and type I collagen cross-linked C-terminal peptide,L4 trabecular space,tibial trabecular space,structural model index,and mRNA and protein expression of DKK1 and GSK3 β in bone marrow tissue(P<0.05).In addition to the increased number of tibial and L4 trabeculae,the trabeculae were arranged in a regular and dense pattern and were connected to a network.To conclude,treadmill exercise may improve osteoporosis in aged rats by activating the wnt/β-catenin signal pathway.

After nearly 30 years of exploration and practice, minimally invasive surgical techniques represented by laparoscopic technology have become an important means for the surgical treatment of gastric cancer. In China, laparoscopic radical resection for locally advanced gastric cancer has been extensively carried out. However, there are still controversies regarding the gastric resection range and methods for advanced gastric cancer. By reviewing relevant domestic and foreign guideline documents and combining team practice experience, this article elaborates on the key points of quality control of laparoscopic gastric resection range for locally advanced gastric cancer from aspects such as tumor localization and gastric resection range for upper, middle and lower gastric tumors. It aims to provide reference for carrying out and promoting laparoscopic radical gastrectomy more safely.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objective:To compare and evaluate recurrence patterns after robotic-assisted gastrectomy (RAG) versus laparoscopic-assisted gastrectomy (LAG).Methods:This was a retrospective cohort study of 2915 consecutive patients with gastric adenocarcinoma confirmed by postoperative histology as T1-4aN0-3M0, who had undergone minimally invasive radical gastrectomy at four large gastric cancer treatment centers (Fujian Medical University Union Hospital: 1426 patients; the First Affiliated Hospital, Nanchang University: 1108; Tianjin Medical University Cancer Institute and Hospital: 196; and First Affiliated Hospital of Xi'an Jiaotong University: 185 cases) between 1 January 2015 and 30 June 2019. 930 patients had undergone RAG (RAG group) and 1985 had undergone LAG (LAG group). We assessed the following characteristics: age, sex, body mass index, American Society of Anesthesiologists score, comorbidities, tumor size, extent of surgery, extent of lymph node dissection, pT, pN, year of surgery, and adjuvant chemotherapy, after propensity score matching (1:1). There were no significant differences in baseline clinical characteristics between the two groups formed by propensity score matching (837 in each group) (all P>0.05). The 3-year recurrence-free survival (RFS), recurrence pattern, and conditional RFS were compared. Results:We detected no significant differences in the overall recurrence rate at 3 years (128/837 [15.3%] vs. 141/837 [16.8%], P=0.387) or time to recurrence (15.7±8.1 months vs. 16.4±8.4 months, P=0.449) between the RAG and LAG groups. Peritoneal recurrence was the most common type of recurrence in both groups (55 [6.6%] vs. 69 [8.2%], P=0.524). The difference in 3-year RFS between the RAG and LAG groups was not statistically significant (83.2% vs. 82.5%, P=0.781). We found that age > 60 years, total gastrectomy, and worse pT stage and pN stage were independent risk factors for recurrence in the study patients (all P<0.05), whereas the surgical procedure (RAG or LAG) was not an independent risk factor for RFS ( P=0.242). The 3-year conditional RFS at various time points was comparable between the two groups (1 year postoperatively: 84.6% vs. 84.7%, P=0.793; 3 years postoperatively: 91.5% vs. 94.9%, P=0.647). Conclusions:In this multicenter study of patients with locally resectable gastric cancer, we demonstrated that RAG performed by surgeons at large gastric cancer centers is not inferior to LAG in 3-year recurrence rate or recurrence patterns.
