ObjectiveTo evaluate the effect of Suanzaoren Tang on the rat model of depression established by solitary culture combined with chronic unpredictable mild stress by reshaping the inflammatory microenvironment and mediating changes in hippocampal synaptic plasticity. MethodsSeventy-two male SD rats were randomized by a random number table into six groups： control group， model group， fluoxetine group （0.003 6 g·kg^-1）， and high-（10 g·kg^-1）， medium-（5 g·kg^-1）， low-dose （2.5 g·kg^-1）Suanzaoren Tang groups， with 12 rats per group. The sucrose preference rate and open field test scores of rats in each group were observed. Western blot was employed to determine the expression levels of the key proteins in the specificity protein 1 （SP1）/sphingosine kinase 1 （SK1）/sphingosine-1-phosphate receptor 1 （S1PR1） signaling pathway， as well as hippocampal proteins synaptophysin Ⅰ （SYNⅠ）， postsynaptic density protein-95 （PSD-95）， and family with sequence similarity 19， member A5 （FAM19A5）. Immunohistochemistry was employed to detect the positive expression of SP1， PSD-95， SYNⅠ， interleukin （IL）-10， and IL-6. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of SP1 and S1PR1. Finally， transmission electron microscopy was employed to observe the ultrastructural changes of hippocampal synapses. ResultsCompared with the control group， the model group exhibited a decrease in sucrose preference index （P<0.01） and reduced total scores for horizontal and vertical movements in the open field test （P<0.01）， which indicated the successful modeling of depression. Moreover， the model group showed reduced synaptic vesicles in the hippocampus （P<0.01）， up-regulated expression of SP1， SK1， S1PR1， and IL-6 （P<0.01）， and down-regulated expression of SYNⅠ， PSD-95， FAM19A5， and IL-10 （P<0.01）. Compared with the model group， high- and medium-dose Suanzaoren Tang and fluoxetine increased the sucrose preference index and the total scores for horizontal and vertical movements in the open field test （P<0.01）. All Suanzaoren Tang groups and the fluoxetine group demonstrated reductions in SP1， SK1， S1PR1， and IL-6 expression （P<0.05， P<0.01）， alongside restored synaptic vesicles in the hippocampus （P<0.05， P<0.01）. ConclusionSuanzaoren Tang modulates hippocampal expression of FAM19A5， SYNⅠ， PSD-95， IL-10， IL-6， and the SP1/SK1/S1PR1 pathway in the rat model of depression. The antidepressant effects may be related to the ability of reducing neuroinflammation and enhancing synaptic plasticity.

OBJECTIVE: To explore the early changes in various liver function indicators in critically injured trauma patients assessed by intelligent calculation method, aiming to develop more advantageous diagnostic and treatment strategies for traumatic liver injury. METHODS: A retrospective study was conducted. Critically injured trauma patients [injury severity score (ISS) ≥ 16, age > 18 years old] admitted to the Emergency Medical Center of Tianjin Fifth Central Hospital from January 1, 2022, to December 1, 2023 were enrolled. ISS score and acute physiology and chronic health evaluation II (APACHE II) assessed by intelligent calculation method were collected upon patient admission to the emergency medical center. Trends in liver function indicators in fasting venous serum were analyzed at 6, 24 and 72 hours after admission, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), lactate dehydrogenase (LDH), albumin (ALB), total bilirubin (TBil), prothrombin time (PT). Patients were grouped based on APACHE II scores into those with APACHE II < 15 and APACHE II ≤ 15, and liver function indicators within 6 hours of admission were compared between the two groups. RESULTS: A total of 112 critically injured trauma patients were included, with 83 males and 29 females, an average age of (47.78±14.84) years old. The median ISS score was 21.0 (18.0, 26.0). The most common cause of injury for critically injured trauma patients was road traffic accidents (68 cases, accounting for 60.71%), followed by falls from heights, compression injuries, heavy object injuries, knife stabs, and explosion injuries. The most common injured areas was the limbs and pelvis (97 cases, accounting for 86.61%), followed by chest injuries, surface skin and soft tissue injuries, abdominal and pelvic organ injuries, head injuries, and facial injuries. The proportion of elevated LDH, AST, and ALT within 6 hours of admission was 77.68%, 79.46%, and 52.68%, respectively, while the proportion of decreased ALB was 75.89%, the abnormal rates of ALP, GGT, TBil, and PT were all below 50%. The ALT and AST levels of patients at 24 hours and 72 hours after admission were significantly lower than those at 6 hours after admission [ALT (U/L): 37.0 (22.0, 66.0), 31.0 (21.2, 52.0) vs. 41.0 (25.0, 71.0), AST (U/L): 55.5 (30.0, 93.5), 40.0 (27.0, 63.2) vs. 69.5 (39.0, 130.8), all P < 0.05]. There was no statistically significant difference in ISS score between APACHE II > 15 group (45 cases) and APACHE II ≤ 15 group [67 cases; 21.0 (18.5, 26.5) vs. 20.0 (17.0, 22.0), P > 0.05]. Nevertheless, compared with patients with APACHE II ≤ 15, patients with APACHE II > 15 have a higher abnormality rate of ALT and AST within 6 hours of admission [ALT abnormal rate: 66.44% (29/45) vs. 44.78% (30/67), AST abnormal rate: 93.33% (42/45) vs. 70.15% (47/67), both P < 0.05], and the levels of ALT and AST were higher [ALT (U/L): 56.0 (30.0, 121.0) vs. 35.0 (21.0, 69.0), AST (U/L): 87.0 (48.0, 233.0) vs. 52.0 (31.0, 117.0), both P < 0.05]. CONCLUSIONS Severe trauma patients frequently exhibit a high incidence of reversible early liver function impairment. Based on intelligent calculation method, the utilization of both the ISS and APACHE II scores demonstrates a distinct advantage in the assessment of their early liver injury.

Objective To explore the potential causal relationship between childhood obesity and the risk of inflammatory bowel disease(IBD)based on Mendel randomization(MR).Methods The genome-wide association study(GWAS)data for childhood obesity included 5 530 cases and 8 318 controls.The GWAS data for IBD included 5 673 cases and 213 119 controls.The GWAS data for ulcerative colitis included 4 320 cases and 210 300 controls.The GWAS data of Crohn's disease included 2 056 cases and 210 300 controls.The risk association between obesity and the occurrence of IBD was analyzed using the inverse variance weighted meth-od(IVW),general model,weighted model,weighted median,and MR-Egger.Results Fourteen independent single nucleotide polymorphisms(SNP)significantly associated with childhood obesity were screened out as instrumental variables.IVW analysis results showed that no potential causal association was found between childhood obesity and IBD(OR=1.048,95%CI:0.976-1.125),ulcerative colitis(OR=1.026,95%CI:0.946-1.113),and Crohn's disease(OR=1.123,95%CI:0.993-1.269,P>0.05).Conclusion There was no causal relationship between childhood obesity and the risk of IBD.

Objective To investigate the setup error in patients with spinal bone metastasis who underwent radiotherapy under the guidance of kilovoltage cone-beam CT (KV-CBCT). Methods A total of 118 patients with spinal metastasis who underwent radiotherapy, including 17 cases of cervical spine, 62 cases of thoracic spine, and 39 cases of lumbar spine, were collected. KV-CBCT scans were performed using the linear accelerators from Elekta and Varian’s EDGE system. CBCT images were registered with reference CT images in the bone window mode. A total of 973 data were collected, and 3D linear errors were recorded. Results The patients with spinal bone metastasis were grouped by site, height, weight, and BMI. The P value of the patients grouped only by site was P<0.05, which was statistically significant. Conclusion When grouped by site in the 3D direction, the positioning effect of cervical spine is better than that of thoracic and lumbar spine. The positioning effect of the thoracic spine is better in the head and foot direction but worse in the left and right direction compared with that of the lumbar spine. Instead of extending or narrowing the margin according to the BMI of patients with spinal metastasis, the margin must be changed according to the site of spinal bone metastasis.

Objective To explore the effects of Bushen ovulation-stimulating decoction on oocyte quality and pregnancy outcome of in vitro fertilization-embryo transfer(IVF-ET)in patients with repeated transplantation failure.Methods From January 2019 to January 2021,86 patients who received IVF-ET again because of repeated transplantation failure in Jinzhong Yingtai Women's&Children's Hospital were randomly divided into control group and observation group,with 43 cases in each group.Progesterone was given 2 days before IVF-ET treatment in both groups,and the observation group was additionally treated with Bushen ovulation-stimulating decoction at the peak of luteinizing hormone in menstrual cycle before transplantation.All the patients in both groups were treated continuously for 3 menstrual cycles.Traditional Chinese medicine symptom score,hormone level,oocyte quality,endometrium and blood flow were observed and compared between the 2 groups.Results After 3 menstrual cycles of treatment,the scores of pale menstrual color,soreness and softness of waist and knees,and dryness in the vagina in the observation group were significantly lower than those in the control group(P<0.05).Three weeks after transplant,the observation group had significantly higher levels of serum progesterone(P)and estradiol(E2)and lower level of follicle stimulating hormone(FSH)than the control group(all P<0.05).On the day of ovulation,the thickness of endometrium in the observation group was significantly higher than that in the control group,and the resistance index(RI)and pulsatility index(PI)of uterine artery in the observation group were significantly lower than those in the control group(P<0.05).The fertilization rate,the number of ovum obtained,clinical pregnancy rate,average gestational weeks of delivery,neonatal weight and one-minute Apgar score in the observation group were significantly higher than those in the control group(P<0.05).The early abortion rate and fetal preterm birth rate in the observation group were significantly lower than those in the control group(P<0.05).Conclusion Bushen ovulation-stimulating decoction can significantly increase the scores of traditional Chinese medicine symptoms,improve blood circulation of uterus,gonadal hormone concentrations and oocyte quality,and reduce the incidence of adverse pregnancy outcomes in patients who repeatedly fail to receive IVF-ET treatment.

BACKGROUND:Semen cuscutae has the effect of tonifying the liver and kidney system and benefiting the essence.The main pathogenesis of osteoarthritis is deficiency of the liver and kidneys.Therefore,it is hypothesized that there is a link between semen cuscutae and osteoarthritis. OBJECTIVE:To explore the potential relationship between osteoarthritis and semen cuscutae and validate the mechanism of semen cuscutae based on the network pharmacology and molecular docking analysis. METHODS:First,the active ingredients and targets of semen cuscutae were screened in TCMSP,and the genes related to osteoarthritis were collected in the disease databases GeneCard's,OMIM and TTD.The intersected genes were taken and then subjected to a series of analyses and screened for hub genes.Through the enrichment analysis of hub genes,the pathway of semen cuscutae acting on osteoarthritis was selected.The role of hub genes was verified by molecular docking.Therefore,the appropriate active ingredients of semen cuscutae were selected for experimental verification. RESULTS AND CONCLUSION:There were 11 active ingredients of semen cuscutae,66 intersection target genes of semen cuscutae and osteoarthritis,and 12 hub genes,including tumor necrosis factor,interleukin 1B,TP53,RAC-alpha serine/threonine protein kinase(AKT1),vascular endothelial growth factor A,matrix metalloproteinase 9,prostaglandin peroxidase 2,cystatinase 3,epidermal growth factor,peroxisome proliferator-activated receptor gamma,interleukin 10,vascular cell adhesion factor 1.After the enrichment analysis of the hub genes,the classical inflammatory pathway,nuclear factor-κB signaling pathway,was selected for subsequent validation of semen cuscutae to alleviate osteoarthritic inflammation.Through the results obtained after molecular docking of each active ingredient and the hub gene of the pathway prostaglandin peroxidase 2,sesamin with the highest affinity was selected for subsequent cell experiments,and the experimental results confirmed that sesamin,the active ingredient of semen cuscutae,could reduce the expression of cyclooxygenase 2 by inhibiting the nuclear factor-κB signaling pathway induced by interleukin-1β.To conclude,sesamin,the active ingredient of semen cuscutae,reduces the expression of cyclooxygenase 2 by inhibiting the nuclear factor-κB signaling pathway induced by interleukin-1β,thereby improving inflammation in osteoarthritis and expanding the therapeutic effect of semen cuscutae in osteoarthritis.
