Perimenopause raises the risk and incidence of depression, whereas the underlying molecular mechanism remains unclear. Disturbed glucose regulation has been widely documented in depressive disorders, which renders the brain susceptible to various stresses such as estrogen depletion. However, whether and how glucose dysfunction regulates depression-like behaviors and neuronal damage in perimenopausal transition remains unexplored. Here, a prominent depressive phenotype was found in perimenopausal mice induced by the ovarian toxin 4-vinylcyclohexene diepoxide (VCD). The VCD depression susceptible group (VCDSS) and the VCD depression resilient group (VCDRES) were determined using a ROC-based behavioral screening approach. We found that the hippocampus, a crucial region linked to depression, had hyperglycemia and mitochondrial abnormalities. Interestingly, oral administration of the SGLT2 inhibitor empagliflozin (EMPA) and intrahippocampal glucose infusion suggest a close relationship between hyperglycemia in the hippocampus and the susceptibility to depression. We verified that cytochrome c oxidase 7c (COX7C) downregulation is a potential cause of the high glucose-induced neuronal injury using proteomic screening and biochemical validations. High glucose causes COX7C to be ubiquitinated in a S-phase kinase associated protein 1 (SKP1)-dependent manner. According to these results, SKP1/COX7C represents a unique therapeutic target and a novel molecular route for treating perimenopausal depression.

Acute pancreatitis (AP) is a common clinical acute abdominal disease, which is characterized by acute onset, rapid development, severe disease, many complications, and high mortality rate. It can progress to severe AP (SAP) if not treated promptly in the early stage. The pathogenesis of AP is complex and involves multiple cellular and molecular levels. It is now clear that oxidative stress and reactive oxygen species (ROS) production are involved in the physiopathological process of AP, which is associated with a low quantity and activity of antioxidant enzymes in pancreatic cells. Nuclear factor E2-related factor 2 (Nrf2) serves as the ''golden key'' to maintain redox homeostasis in tissue cells and constitutes an important signaling pathway for antioxidant response and inflammation in vivo by collaborating with downstream antioxidant enzymes such as heme oxygenase-1 (HO-1). Traditional Chinese medicine has unique efficacy in treating diseases due to its multi-component, multi-target, multi-drug delivery, and multi-formulation characteristics. Based on the concept of synergy between traditional Chinese and Western medicine, traditional Chinese medicine is becoming a new craze in the treatment of AP. The level of oxidative stress and Nrf2/HO-1 signaling pathway in AP pancreatic tissue are in a dynamic change process, and the intervention of traditional Chinese medicine can clean ROS production, affect the inflammatory pathway, and reduce oxidative stress damage, so as to protect against pancreatic injury. This suggests that this pathway plays an important role in AP. This article reviews the recent literature on the regulation of the Nrf2/HO-1 signaling pathway by traditional Chinese medicine for AP and summarizes that the monomers of traditional Chinese medicine targeting this pathway are mainly heat-clearing and detoxifying, blood-activating and blood-stasis-removing, and Qi benefiting and middle warming, and the compounds of traditional Chinese medicine include Yinchenhao Decoction and QingYi Ⅱ, so as to provide a new direction for the prevention and treatment of AP and further drug development.

Objective:
To explore and validate the potential targets of Paeoniae Radix Alba (P. Radix, Bai Shao) in protecting against chemical liver injury through network pharmacology, molecular docking technology, and in vitro cell experiments.
Methods:
Network pharmacology was used to identify the common potential targets of P. Radix and chemical liver injury. Molecular docking was used to fit the components, which were subsequently verified in vitro. A cell model of hepatic fibrosis was established by activating hepatic stellate cell (HSC)-LX2 cells with 10 ng/mL transforming growth factor-β1. The cells were exposed to different concentrations of total glucosides of paeony (TGP), the active substance of P. Radix, and then evaluated using the cell counting kit-8 assay, enzyme-linked immunosorbent assay, and western blot.
Results:
Analysis through network pharmacology revealed 13 key compounds of P. Radix, and the potential targets for preventing chemical liver injury were IL-6, AKT serine/threonine kinase 1, jun proto-oncogene, heat shock protein 90 alpha family class A member 1 (HSP90AA1), peroxisome proliferator activated receptor gamma (PPARG), PTGS2, and CASP3. Gene Ontology (GO) enrichment analysis indicated the involvement of response to drugs, membrane rafts, and peptide binding. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the main pathways involved lipid and atherosclerosis and chemical carcinogenesis-receptor activation. Paeoniflorin and albiflorin exhibited strong affinity for HSP90AA1, PTGS2, PPARG, and CASP3. Different concentrations of TGP can inhibit the expression of COL-Ⅰ, COL-Ⅲ, IL-6, TNF-α, IL-1β, HSP-90α, and PTGS2 while increasing the expression of PPAR-γ and CASP3 in activated HSC-LX2 cells.
Conclusion
P. Radix primarily can regulate targets such as HSP90AA1, PTGS2, PPARG, CASP3. TGP, the main active compound of P. Radix, protects against chemical liver injury by reducing the inflammatory response, activating apoptotic proteins, and promoting the apoptosis of activated HSCs.

ObjectiveTo observe the effect of deep muscle stimulation on muscle structure and function in children with spastic cerebral palsy. MethodsFrom January, 2023 to March, 2024, 30 children with spastic cerebral palsy in Beijing Bo'ai Hospital were randomly divided into control group (n = 15) and intervention group (n = 15). Both groups received conventional rehabilitation therapy, while the intervention group added deep muscle stimulation, for four weeks. Before and after training, the gastrocnemius muscle was examined by ultrasound diagnosis system in two aspects: transverse incision and longitudinal incision. Indicators included fascicle length, muscular thickness, cross sectional area and pennation angle. The modified Ashworth Scale (MAS) was used to assess the muscle tension of the lower extremity of the affected side. The standing, walking, running and jumping function were evaluated by Gross Motor Function Measure (GMFM) D and E areas. ResultsAfter training, the fascicule length and pennation angle improved significantly in both groups (|t| > 6.329, P < 0.001), and they were better in the intervention group than in the control group (|t| > 2.347, P < 0.05); the scores of MAS decreased in both groups (t > 2.432, P < 0.05), and were better in the intervention group than in the control group (t = 2.140, P < 0.05); the scores of GMFM D and E areas significantly decreased in both groups (|t| > 8.473, P < 0.001), and were better in the intervention group than in the control group (|t| > 2.191, P < 0.05). ConclusionDeep muscle stimulation could improve the fascicule length and pennation angle, and improve the spasticity and motor function of lower extremities in children with spastic cerebral palsy.

Objective We aimed to investigate(i)the preventive and therapeutic effects of Huogu Muli Prescription(HGMLP),a Chinese medical compound consisting of epimedii folium,drynariae rhizoma,and ostreae concha,on postmenopausal osteoporosis(PMOP)rats and(ii)whether it exerts its effects by regulating the osteoclast-osteogenesis balance.Methods Forty-eight female Sprague-Dawley rats were randomly divided into the following six groups:(i)the sham-operated group,(ii)the model group,(iii)the Qianggu Capsule group,(iv)the calcium carbonate group,and(v,vi)the HGMLP low-dose and high-dose groups(n = 8 rats per group).After adaptive feeding,rats in all groups except the sham-operated group were treated with bilateral ovarian castration to establish the PMOP model.Each day,rats in the Qianggu Capsule group received 0.054 g/kg Qianggu Capsule suspension intragastrically,rats in the calcium carbonate group received 1.670 g/kg calcium carbonate suspension intragastrically,and rats in the HGMLP low-dose and high-dose groups received 0.188 g/kg and 0.375 g/kg HGMLP intragastrically.Rats in the sham-operated group and the model group received an equal volume of normal saline intragastrically.After 90 consecutive days,serum estradiol(E2),estrogen receptor α(ERα),procollagen typeⅠN propeptide(PINP),and tartrate-resistant acid phosphatase 5b(TRACP-5b)were detected by ELISA.Total antioxidant capacity(T-AOC),superoxide dismutase(SOD),catalase(CAT),and malondialdehyde(MDA)levels were measured by colorimetry.Bone mineral density(BMD),trabecular number(Tb.N),trabecular separation/spacing(Tb.Sp),trabecular thickness(Tb.Th),and structure model index(SMI)were measured by Micro-CT,and the microstructure of cancellous bone was observed.The expressions of osteoprotegerin(OPG),receptor activator of nuclear factor-κB(RANK),RANK ligand(RANKL),phosphorylation of forkhead box O3(FoxO3α),Wnt2,β-catenin,and peroxisome proliferator-activated receptor γ(PPARγ)in rat femur tissue were detected by Western blotting.Results(i)The serum levels of E2 and ERα increased in the Qianggu Capsule group and HGMLP groups,compared with the model group(all P<0.05).(ii)Compared with the model group,the serum levels of PINP,TRACP-5b decreased and PINP/TRACP-5b increased in both the Qianggu Capsule group and HGMLP high-dose group(all P<0.05).(iii)The activities of T-AOC,AOD,and CAT in the Qianggu Capsule group and HGMLP groups were higher than those in the model group,while the content of MDA lower(all P<0.05).(iv)Compared with the model group,the femoral BMD,Tb.Th,and Tb.N increased in the Qianggu Capsule group and HGMLP groups,while the femoral Tb.Sp and SMI decreased(all P<0.05);the femoral BMD increased and the Tb.Sp decreased in the calcium carbonate group(all P<0.05).(v)The protein expressions of RANKL,RANK,FoxO3α,and PPARγ in the Qianggu Capsule group and HGMLP groups were lower than those in the model group,while the protein expressions of OPG,Wnt2,and β-catenin were higher(all P<0.05).Conclusion HGMLP can significantly increase estrogen levels,inhibit osteoclast differentiation,and inhibit bone resorption in the PMOP rats.It also alleviates oxidative stress,promotes osteogenic differentiation,inhibits lipogenic differentiation,improves bone formation,and recovers the balance between osteoclasts and osteoblasts,thus achieving prevention and treatment of PMOP.The potential mechanism of HGMLP may be related to regulation via the OPG/RANKL/RANK or FoxO3α/Wnt2/β-catenin/PPARγ pathways.

Objective:To explore the causal association of glucose-lipid metabolism and obesity indicators with myocardial infarction by a two-sample Mendelian randomization analysis.Methods:Single nucleotide polymorphisms (SNPs) related to phenotypes were obtained from genome-wide association study databases. The body mass index (BMI) and glycated hemoglobin dataset includes 99 998 samples and 8 126 035 SNPs; the waist-to-hip ratio dataset includes 224 459 samples and 2 562 516 SNPs; the waist circumference and hip circumference dataset includes 462 166 samples and 9 851 867 SNPs; the fasting glucose dataset includes approximately 12 million SNPs; the low-density lipoprotein cholesterol (LDL-C) dataset includes 201 678 samples and 12 321 875 SNPs; the high-density lipoprotein cholesterol (HDL-C), and triglycerides dataset includes 156 109 samples and 15 784 414 SNPs; and the body fat percentage, whole-body fat mass, trunk fat percentage, and trunk fat mass dataset includes 454 588 samples and 9 851 867 SNPs. This study primarily used inverse-variance weighted method to analyze the associations between various exposure factors and outcomes. Heterogeneity among SNPs was assessed using Cochran′s Q test, and horizontal pleiotropy of SNPs was examined using the MR-Egger method. Additionally, a multivariable MR approach was used to adjust for BMI, further validating associations between exposure factors and the risk of myocardial infarction. Results:Higher BMI ( OR=1.070, 95% CI: 1.041-1.100), waist-to-hip ratio ( OR=1.366, 95% CI: 1.113-1.677), LDL-C ( OR=1.638, 95% CI: 1.488-1.803), triglycerides ( OR=1.445, 95% CI: 1.300-1.606), waist circumference ( OR=1.841, 95% CI: 1.650-2.055), hip circumference ( OR=1.247, 95% CI: 1.132-1.372), body fat percentage ( OR=1.795, 95% CI: 1.568-2.055), whole-body fat mass ( OR=1.519, 95% CI: 1.381-1.670), trunk fat percentage ( OR=1.538, 95% CI: 1.374-1.723), and trunk fat mass ( OR=1.421, 95% CI: 1.294-1.561), as well as lower HDL-C ( OR=0.799, 95% CI: 0.729-0.875), have causal effects on myocardial infarction (all P<0.05). After adjusting for BMI, hip circumference, trunk fat percentage, and trunk fat mass were no longer associated with myocardial infarction. However, waist-to-hip ratio ( OR=1.457, 95% CI: 1.132-1.877), fasting glucose ( OR=1.191, 95% CI: 1.024-1.383), glycated hemoglobin ( OR=1.129, 95% CI: 1.034-1.233), LDL-C ( OR=1.592, 95% CI: 1.314-1.929), triglycerides ( OR=1.410, 95% CI: 1.279-1.553), waist circumference ( OR=1.922, 95% CI: 1.448-2.551), body fat percentage ( OR=1.421, 95% CI: 1.072-1.884), and whole-body fat mass ( OR=1.295, 95% CI: 1.031-1.626) remained positively associated with myocardial infarction, while HDL-C ( OR=0.809, 95% CI: 0.729-0.897) remained negatively associated. Conclusions:Abdominal obesity and dysregulation of glucose-lipid metabolism are risk factors for myocardial infarction. Screening for glucose-lipid metabolism (fasting glucose, HDL-C, LDL-C, triglycerides) and obesity-related indicators (waist circumference, waist-to-hip ratio, body fat percentage, and whole-body fat mass) is of great importance for the primary prevention of myocardial infarction.

Objective:
To investigate the trends in mortality of malignant tumors in Ningbo City, Zhejiang Province from 2002 to 2022, so as to provide the evidence for formulating malignant tumor control strategies in Ningbo City. Methods The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC).
Methods:
The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC).
Results:
The crude mortality of malignant tumors was 186.43/105 to 221.24/105 in Ningbo City from 2002 to 2022, which showed a tendency towards a rise (AAPC=0.76%), and both the Chinese- (AAPC=-2.64%) and world-standardized mortality (AAPC=-2.74%) appeared a tendency towards a decline (all P<0.05). The world-standardized mortality of malignant tumors presented three changes in Ningbo City from 2002 to 2022, with a more remarkable decline from 2011 to 2018 (APC=-3.53%) than from 2002 to 2011 (APC=-2.10%) and from 2018 to 2022 (APC=-2.00%) (all P<0.05). The annual decline in mortality of malignant tumors was higher in men (Chinese-standardized mortality: AAPC=-2.68%; world-standardized mortality: AAPC=-2.75%) than in women (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%), and higher in urban areas (Chinese-standardized mortality: AAPC=-2.85%; world-standardized mortality: AAPC=-2.92%) than in rural areas (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%) (all P<0.05). The mortality of malignant tumors appeared a tendency towards a rise with age in Ningbo City, with the highest mortality in residents at ages of 85 years and older (1 447.13/105). Death from malignant tumors were responsible for 31.86% of all causes of death in Ningbo City, and the five most common causes of cancer death included lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer. In addition, the world-standardized mortality of pancreatic cancer (AAPC=3.92%), prostate cancer (AAPC=4.71%), and cervical cancer (AAPC=1.60%) appeared a tendency towards a rise in Ningbo City (all P<0.05).
Conclusions
The crude mortality of malignant tumors appeared a tendency towards a rise in Ningbo City from 2002 to 2022, while the standardized mortality showed a tendency towards a decline. Management of malignant tumors should be given a high priority among men and rural residents, and lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer should be emphasized.

Objective:To study the learning curve in laparoscopic left lateral hepatic sectionectomy.Methods:The clinical data of 62 consecutive patients who underwent left lateral hepatic sectionectomy by a single operator from February 2015 to May 2022 in General Hospital of Northern Theater Command were retrospectively analyzed. There were 22 males and 40 females, with mean ±s.d. of (50.7±11.7) years. The learning curve was depicted and evaluated by using the cumulative summation test. The general information, operation and postoperative indicators of the growth level group and the master level group were compared.Results:The average operation time of the 62 consecutive subjects was (172.9±70.1) minutes. Intraoperative blood loss was 100 (50, 200) ml. Two patients were converted to open hepatectomy. Clavien-Dindo grade I postoperative complications occurred in 20 patients (32.3%), with grade Ⅱ in 1 patient (1.6%) and grade Ⅲb in another patient (1.6%). The learning curve reached its highest point on the 20th patient by using the cumulative summation test. The study subjects were then assigned into the growth level group (patient 1-20) and the master level group (patient 21-62). The master level group had a significantly wider spread of patient age [(52.9±11.0) years vs (46.1±11.9) years], decreased operation time [(146.8±55.6) min vs (227.9±66.7) min], shortened drainage tube removal time [4(3, 5) d vs 6(4, 7) d] and decreased postoperative hospital stay [5(5, 7) d vs 6.5(4, 9) d] (all P<0.05) when compared with the growth level group. Conclusion:Left lateral hepatic sectionectomy was safe and feasible, and a single operator went through a learning curve of 20 patients before he/she could master the operation more proficiently.

The paper reported a patient under maintained hemodialysis for 11 years, with a large mass appeared in the right thigh after local injury. The mass was clinically considered as tumoral calcinosis combined with clinical, imaging and pathological findings. Several treatments such as enhancing dialysis adequacy, low calcium dialysate, calcimimetic agent, non-calcium- phosphorus binding agents, parathyroidectomy and intravenous infusion of sodium thiosulfate could not vanish the mass. Finally, the lump was surgically removed. The treatment of tumoral calcinosis in the hemodialysis patient can provide a instruction for similar situations in clinical practice.
