In recent years， the incidence of depression among adolescents has increased significantly， becoming a serious global public health problem. There is a close relationship between adolescent depression and lipid metabolism abnormalities. However， the mechanisms underlying this association have not been fully elucidated. This article provides a review of the mechanisms and interventions linking adolescent depression and lipid metabolism abnormalities， aiming to offer new ideas for interventions in adolescent depression. Using computerized searches of the China National Knowledge Infrastructure （CNKI）， Wanfang Data， PubMed， and Web of Science， studies on the mechanisms and interventions related to adolescent depression and lipid metabolism were collected， with the search period extending up to October 10， 2025. Two researchers independently conducted literature screening and extracted basic information from the included studies. A total of 12 original studies were included. The results indicate that adolescent depression is associated with certain lipid metabolites. Neurobiological factors， immune inflammation， oxidative stress， and gut microbiota imbalance play important roles in this association. In addition， lipid metabolites such as omega-3 polyunsaturated fatty acids （ω-3 PUFAs） have a significant ameliorating effect on adolescent depression. ［Funded by Shenzhen Fund for Guangdong Provincial High-level Clinical Key Specialties （number， SZGSP013）； Shenzhen Science and Technology Program （number， 20210617155253001）］

Chaihu Guizhi Ganjiangtang was first recorded in the Treatise on Cold Damage （Shang Han Lun）. This prescription is composed of Bupleuri Radix， Scutellariae Radix， Cinnamomi Ramulus， Zingiberis Rhizoma， Trichosanthis Radix， Ostreae Concha， and Glycyrrhizae Radix et Rhizoma. It has the effects of soothing Lesser Yang， warming the spleen， and stimulating the generation of body fluid. It is mainly used to treat digestive tract diseases such as chronic cholecystitis （CC）， irritable bowel syndrome， and non-alcoholic fatty liver disease. Dyspepsia caused by CC presents a variety of gastrointestinal symptoms such as abdominal pain， poor appetite， postprandial fullness， aversion to greasy food， soft stool， and bitter mouth， being a type of biliary dyspepsia. In modern medicine， dyspepsia caused by CC is mainly managed by medical treatment and surgical treatment. Internal medicine mainly focuses on reducing inflammation， promoting the function of gallbladder， resolving stones， alleviating spasms， and relieving the pain for CC， demonstrating definite short-term efficacy but suffering from single effects， high recurrence rate， and poor compliance. Although surgical treatment can cure cholecystitis， it is accompanied by the increased incidence of adverse events such as abdominal pain， diarrhea， and dyspepsia. Modern clinical studies have confirmed that Chaihu Guizhi Ganjiangtang can significantly alleviate the symptoms such as abdominal pain and dyspepsia of CC patients. Pharmacological studies have found that Chaihu Guizhi Ganjiangtang mainly contains active ingredients such as Bupleuri Radix saponins， baicalin， cinnamaldehyde， gingerol， Trichosanthis Radix polysaccharide， Ostreae Concha polysaccharide， and Glycyrrhizae Radix et Rhizoma total flavonoids. Chaihu Guizhi Ganjiangtang can ameliorate the symptoms of dyspepsia caused by CC by inhibiting inflammatory responses， improving gallbladder contraction and gastrointestinal motility， regulating the bile acid-intestinal flora axis and the brain-gut axis， and modulating blood lipids through multiple targets. By reviewing the previous literature， this article summarizes the research progress in the treatment of dyspepsia caused by CC with Chaihu Guizhi Ganjiangtang and its main active ingredients as well as the pathogenesis of this disease and puts forward the shortcomings and improvement strategies for the current research. The review aims to provide a reference for the further research on Chaihu Guizhi Ganjiangtang in the treatment of dyspepsia caused by CC.

ObjectiveTo investigate the feasibility， safety， and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt （SA-TIPS） in the treatment of portal hypertension comorbid with complex portal vein thrombosis， including cavernous transformation of the portal vein （CTPV）. MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital， Capital Medical University， from November 2023 to January 2025， including general status， technical data of the surgical process （surgical success rate， puncture times， time of operation， the number of stents used， and the length of shunt）， perioperative complications， and surgical recovery. The change in portal pressure gradient （PPG） after shunt was compared， and the rate of reaching the standard for PPG reduction was calculated， as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients， 34 （94.4%） underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% （6/36）， including 3 cases of thoraco-abdominal hemorrhage， 2 cases of intraoperative arrhythmia， and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS （t=19.85， P<0.01）， and the patients achieving a ≥50% reduction in PPG accounted for 76.5% （26/34）. Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate， a favorable safety profile， and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis （including CTPV）， and therefore， it holds promise for clinical application.

Objective:To explore the clinical characteristics and prognostic factors of primary bladder adenocarcinoma（ACB）.Methods:The clinical data of 33 patients with primary ACB who underwent surgical treatment in the Department of Urology of Peking University Third Hospital from July 2003 to January 2024 were retrospectively analyzed. There were 5 females and 28 males，with an average age of（61.3 ± 11.5）years. Twelve patients had comorbidities（6 hypertension，2 coronary heart disease，5 diabetes mellitus，and 3 cerebrovascular diseases）and 12 had a smoking history. The mean body mass index（BMI）was（24.8 ± 3.2）kg/m 2. The maximum tumor diameter measured by enhanced computed tomography（CT）was（29.7 ± 12.7）mm. The preoperative neutrophil-to-lymphocyte ratio（NLR）was 3.4 ± 3.2，and the systemic immune-inflammation index（SII）was（582 ± 496）× 10 9/L.Patients were divided into two groups according to the surgical approach：the radical cystectomy group（ n = 23）and the bladder-sparing group（ n = 10）. For the radical cystectomy group，there were 19 males and 4 females，with a mean age of（59.9 ± 12.6）years. Five patients had comorbidities（3 hypertension，1 coronary heart disease，1 diabetes mellitus，and 2 cerebrovascular diseases）. Eight patients had a smoking history，with a mean BMI of（25.2 ± 3.5）kg/m 2. The maximum tumor diameter was（33.6 ± 10.9）mm，the preoperative NLR was 3.5 ± 3.5，and the SII was（618 ± 558）× 10 9/L. For the bladder-sparing group，there were 9 males and 1 female，with a mean age of（64.5 ± 8.2）years. Seven patients had comorbidities（3 hypertension，1 coronary heart disease，4 diabetes mellitus，and 1 cerebrovascular diseases）. Four patients had a smoking history，with a mean BMI of（23.5 ± 2.3）kg/m 2. The maximum tumor diameter was（20.7 ± 12.5）mm，the preoperative NLR was 3.1 ± 2.2，and the SII was（501 ± 323）× 10 9/L. Statistically significant differences were observed between the two groups in terms of comorbidities（ P = 0.008）and maximum tumor diameter（ P = 0.006），while no significant differences were found in other data（ P > 0.05）. The Kaplan-Meier survival curve was drawn，and Cox regression was used to analyze the prognostic factors of progression-free survival（PFS）and overall survival（OS）of patients. Results:Among the 33 patients，low-grade adenocarcinoma and high-grade adenocarcinoma accounted for 60.6% and 39.4% respectively according to the postoperative pathology，and 3 patients had positive surgical margins. There were 22 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，and 1 case of distant metastasis. The patients in tumor stages Ⅰ—Ⅳ were 9 cases（27.3%），8 cases（24.2%），7 cases（21.2%），and 9 cases（27.3%）respectively. Nine patients received postoperative adjuvant therapy，including 6 with adjuvant chemotherapy，2 with adjuvant chemotherapy combined with radiotherapy，and 1 with adjuvant immunotherapy. In the radical cystectomy group（ n = 23），there were 13 cases of low-grade and 10 cases of high-grade pathological grading，2 cases with positive margins，19 cases of muscle-invasive bladder adenocarcinoma，5 cases of lymph node metastasis，1 case of distant metastasis，and 5 patients received adjuvant therapy（4 cases of adjuvant chemotherapy，and 1 case of adjuvant immunotherapy）. In the bladder-sparing group（ n = 10），there were 7 cases of low-grade，3 cases of high-grade pathological grading，1 case with positive margins，3 cases of muscle-invasive bladder adenocarcinoma，zero lymph node or distant metastasis，and 4 patients received adjuvant therapy（2 cases of adjuvant chemotherapy，and 2 cases of combined adjuvant chemotherapy and radiotherapy）. A statistically significant difference was found in the proportion of muscle-invasive bladder adenocarcinoma between the two groups（ P = 0.006），while no significant differences were observed in other data（ P > 0.05）.The median follow-up duration of the patients was 28.0 months，the median PFS was 86.0 months，and the median OS was 90.0 months. The 2-year PFS and OS were 65.4% and 73.1% respectively. The 5-year PFS and OS were 54.2% and 56.5% respectively. The Kaplan-Meier survival analysis showed that there were no significant differences in PFS（ P = 0.777）and OS（ P = 0.585）between the radical cystectomy group and the bladder-preserving group. Female（ P = 0.011），BMI < 25 kg/m2（ P = 0.038），and positive surgical margins（ P < 0.01）were associated with poorer PFS. Aged ≥ 70 years（ P = 0.003），lymph node metastasis（ P = 0.041），and positive surgical margins（ P = 0.025）were associated with poorer OS，and patients in the adjuvant therapy group had better OS（ P = 0.005）. Multivariate Cox regression analysis indicated that positive surgical margins（HR 10.2， P = 0.012）were an independent impact factor for PFS，and positive surgical margins（HR 39.8， P = 0.001）and adjuvant therapy（HR 0.12， P = 0.021）were independent impact factors for OS. Conclusions:Positive surgical margins and adjuvant therapy are independent impact factors for the prognosis of patients with primary ACB.

Objective:To investigate the relationship between nerve growth factor (NGF) concentration in follicular fluid and abnormal menstrual cycle in infertile patients with polycystic ovary syndrome (PCOS).Methods:A retrospective cohort study was conducted on 100 infertile patients with PCOS who underwent in vitro fertilization and embryo transfer (IVF-ET) at Department of Obstetrics and Gynecology, Peking University Third Hospital from March 2017 to June 2019. For comparison, the 100 patients with PCOS were divided into low NGF group ( n=50) and high NGF group ( n=50) based on the median NGF concentration (1 644.03 ng/L) in follicular fluid. Baseline characteristics, menstrual status and clinical outcomes of assisted reproductive technology were compared. We performed multiple linear regression analysis to examine the effect of NGF in follicular fluid on menstrual cycle length for multivariate analysis. Results:1) PCOS patients in the low NGF group had significantly higher body mass index [(27.24±5.17) kg/m 2] and white blood cell count [7.31(5.99, 8.43)×10 9/L ] than those in the high NGF group [(25.03±4.46) kg/m 2, P=0.024; 5.95(5.08,7.01)×10 9/L, P=0.001], while high-density lipoprotein cholesterol [1.15 (0.98, 1.36) mmol/L] and basic follicle-stimulating hormone level [6.51 (5.10,7.95) U/L] in the low NGF group were significantly lower than those in the high NGF group [1.36 (1.09,1.52) mmol/L, P=0.039;6.51 (5.10,7.95)U/L, P=0.040]. 2) PCOS patients in the low NGF group had significantly higher menstrual cycle length [60.00 (35.00, 180.00) d] than the high NGF group [32.50 (27.00,67.50) d, P=0.001]. 3) Multiple linear regression analysis revealed that after adjustment for body mass index, age, infertility duration, infertility type, and glucose and lipid metabolic parameters, the NGF concentration in the follicular fluid independently and negatively correlated with menstrual cycle length ( P<0.05). 4) The NGF concentration in follicular fluid was not correlated with assisted reproductive outcomes. Conclusion:NGF concentration in follicular fluid is closely related to the degree of menstrual cycle abnormalities in patients with PCOS.

Objective:To develop genetic testing quality control material which has good biological compatibility that can simulate the real sample properties.Methods:Study of the quality control material. The quality control matertial was prepared by embedding the cells and DNA containing specific gene mutations in a biological matrix formed by cross-linking γ-polyglutamic acid and gelatin, followed by formalin fixation and paraffin embedding. Fourier infrared spectroscopy and scanning electron microscopy were used to analyze the morphology and structure of the quality control material. The repeatability and homogeneity were verified by detecting the DNA extraction amount and mutation frequency at different parts of the quality control material. The quality control material was stored at 25 ℃ for 16 weeks, and the stability was verified by detecting the DNA extraction amount, mutation frequency and DNA fragment distribution.Results:The results of Fourier infrared spectroscopy and scanning electron microscopy analysis indicated that the quality control material prepared in this study was formed by cross-linking and had a dense three-dimensional framework structure. The amount of DNA extraction and mutation frequency from different parts of the quality control material varied within a small range ( CV<10%). After storage at 25 ℃ for 16 weeks, the DNA extraction amount and mutation frequency of the quality control material varied within a small range ( CV<5%), and the distribution range of the DNA fragments did not show significant change compared to the day of preparation of the quality control material. Conclusion:This study successfully prepared a genetic testing quality control material based on cross-linked biological matrix, which exhibited good repeatability, homogeneity and stability.

Objective To investigate the protective effects of butyrate on sepsis-related myocardial dys-function.Methods Thirty healthy 8-week-old male Sprague-Dawley rats were randomly divided into three groups:sham operation group(SH,n=10),sepsis group(CL,n=10),and butyrate group(BU,n=10).The CL and BU groups underwent cecal ligation and puncture(CLP)to establish sepsis models,while the SH group received the same surgical procedure without cecal ligation or puncture.Within 30 minutes post-opera-tion,the SH and CL groups received 5 mL normal saline via gavage,whereas the BU group was administered 5 mL sodium butyrate solution(500 mg/kg)in normal saline.Cardiac output(CO)and ejection fraction(EF)were compared among the three groups.Myocardial histopathological injury was assessed by HE staining,and mitochondrial ultrastructural damage was observed by electron microscopy.Serum levels of brain natriuretic peptide(BNP),cardiac troponin Ⅰ(cTnⅠ),and butyrate were compared among groups.Western blot analysis was performed to detect and compare the expression levels of long-chain acyl-CoA synthetase 4(ACSL4)and glutathione peroxidase 4(GPX4)in myocardial tissues.Results After intervention,the BNP and cTnⅠ levels in the CL group were higher than those in the SH group,while CO and EF were lower than those in the SH group(P＜0.05).The BNP and cTnⅠ levels in the BU group were lower than those in the CL group,whereas CO and EF levels were higher than those in the CL group(P＜0.05).HE staining of myocardial tissues re-vealed more severe inflammatory cell infiltration and myocardial cell edema in the CL group compared with the SH group,while the BU group showed reduced inflammatory cell infiltration.Mitochondrial membrane in-tegrity was impaired in the CL group manifested by unclear cristae,swelling,vacuolar degeneration and rup-ture,whereas mitochondrial damage was attenuated in the BU group.Serum butyrate levels were measured as(61.7±21.6)μg/mL,(95.3±16.6)μg/mL and(302.2±49.7)μg/mL in the CL,SH and BU groups respec-tively(P＜0.05).The ACSL4 expression in the CL group was higher than that in the SH group,while GPX4 protein expression was lower than that in the SH group(P＜0.05).The BU group exhibited lower ACSL4 expression and higher GPX4 protein expression compared with the CL group(P＜0.05).Conclusion Buty-rate can ameliorate myocardial injury in septic rats,and its protective effect may be associated with the inhibi-tion of myocardial ferroptosis.

Objective To study the predictive value of the Prognostic Assessment Scale for Patients with Spontaneous Intracerebral Hemorrhage(ICH-LR2S2)and the Prehospital Risk Assessment Scale for Prehospital Deterioration Risk Assessment Scale(ICH-APS)for the development of stroke-associated pneu-monia(SAP)in patients with spontaneous intracerebral hemorrhage.Methods A total of 349 patients with spontaneous intracerebral hemorrhage who were hospitalized for the first time in this hospital from July 2023 to July 2024 were selected as the research subjects.The general demographic data and medical documentations of the patients were collected,and ICH-LR2S2 score and ICH-APS score were carried out within 48 hours after admission.According to whether pneumonia occurred within 7 days after admission,the patients were divided into the SAP group and the non-SAP group,and the diagnostic efficiency of the ICH-LR2S2 score and ICH-APS score for SAP in patients with spontaneous intracerebral hemorrhage was evaluated.Results Among the 349 patients with spontaneous intracerebral hemorrhage,98 patients(28.08％)had pneumonia.The results of multivariate logistic regression analysis showed that age,history of chronic obstructive pulmonary disease(COPD),nasogastric tube,tracheal intubation,National Institutes of Health Stroke Scale(NIHSS)score,Glasgow Coma Scale(GCS)score,C-reactive protein,fasting blood glucose,dysphagia,ICH-LR2S2 score,ICH-APS-A score,and ICH-APS-B score were independent influencing factors for SAP in patients with spontane-ous intracerebral hemorrhage(P＜0.05).The results of the receiver operating characteristic(ROC)curve showed that the ICH-LR2S2 score had the highest diagnostic efficiency for SAP in patients with spontaneous intracerebral hemorrhage,with an area under the curve(AUC)of 0.837,a sensitivity of 0.827,a specificity of 0.783,and a Youden index of 0.610.Conclusion ICH-LR2S2 score has a high predictive value for the occur-rence of SAP in patients with spontaneous intracerebral hemorrhage.
