ObjectiveTo observe the clinical effect of modified Huanglian Wendantang on cardiovascular risk factors in patients with metabolic syndrome under the guidance of treating disease before its onset. MethodsA total of 82 patients with metabolic syndrome treated in the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from July 2023 to July 2024 were selected and allocated into an observation group （41 cases） and a control group （41 cases） by the random number table method. The control group received routine treatment， and the observation group was treated with modified Huanglian Wendantang on the basis of routine treatment. Both groups were treated for 8 weeks. The therapeutic effects on TCM symptoms after treatment in the two groups were evaluated. The levels of obesity degree indicators， blood pressure indicators， glucose and lipid metabolism indicators， inflammatory factors， and vascular endothelial function indicators before and after treatment in the two groups were measured， and the treatment safety was evaluated. ResultsAfter treatment， the total response rate of TCM symptoms in the observation group was 97.56% （40/41）， which was higher than that （87.80%， 36/41） in the control group （χ²=5.205， P<0.05）. After treatment， both groups showed declines （P<0.05） in systolic blood pressure （SBD）， diastolic blood pressure （DBP）， triglyceride （TG）， total cholesterol （TC）， low density lipoprotein cholesterol （LDL-C）， fasting blood glucose， 2-hour postprandial blood glucose （2 h PG）， glycosylated hemoglobin （HbA1c）， fasting insulin （FINS）， Homeostatic Model Assessment for Insulin Resistance （HOMA-IR）， body mass index （BMI）， waist circumference （WC）， waist-to-hip ratio （WHR）， leptin （LEP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， endothelin-1 （ET-1）， and inducible nitric oxide synthase （iNOS）. Moreover， the declines in the observation group were more obvious than those in the control group （P<0.05， P<0.01）. After treatment， both groups showed elevated levels of high density lipoprotein cholesterol （HDL-C）， adiponectin （ADP）， nitric oxide （NO）， and endothelial nitric oxide synthase （eNOS） （P<0.05）， and the above indexes in the observation group were higher than those in the control group （P<0.01）. ConclusionUnder the guidance of the thought of treating disease before its onset， modified Huanglian Wendantang was used to treat patients with metabolic syndrome. The decoction improved the clinical efficacy by ameliorating IR to improve insulin sensitivity， reducing inflammation， and protecting the vascular endothelial function. It inhibits cardiovascular risk factors without inducing adverse reactions， being worthy of clinical application and promotion.

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5％vs 28.6％,70.6％vs 32.1％,58.8％vs28.6％,29.4％vs3.6％,29.4％vs 3.6％,P＜0.05),MCD were more frequently found(58.8％vs 10.7％,P=0.001),GCB were rarely found(17.6％vs 50.0％,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P＜0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P＜0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.

Objective To study the hemodynamic effects of enhanced external counter pulsation(EECP)on typical coronary artery disease and microcirculation angina.Methods A physiological model of the right dominant coronary artery,including the coronary conduit arteries and coronary microcirculation,was established using lumped parameter models.Pathological conditions,such as one-vessel lesions,three-vessel lesions,and microcirculation angina,were simulated.EECP intervention models were established,and the hemodynamic effects of EECP on pathological models was simulated.Results The simulation results of the coronary physiological model,pathological models,and EECP intervention model established in this study were consistent with experimental data in related literature.EECP improved coronary blood flow in all three pathological conditions.For one-vessel lesions,EECP could not recover the blood flow of left main coronary artery to a normal level after the stenosis rate reached 80%-85%.For three-vessel lesions,EECP treatment could not be used if the stenosis rate in one of the three vessels exceeded 90%.For microcirculation angina,EECP was effective when critical condition myocardial blood flow was>1.03 mL/min·g and coronary flow reserve was>1.64.Conclusions The model of coronary disease under EECP interference established in this study meets expectations,and the obtained simulation data have certain reference values for the clinical application of EECP.

OBJECTIVE To study the pharmacological substance basis of Shaoyao gancao decoction for relieving acute and chronic pain. METHODS The antispasmodic effect of Shaoyao gancao decoction， ethyl acetate extract of Shaoyao gancao decoction and its effluent part of macroporous resin and 90% ethanol elution part of macroporous resin （the concentration of 4 drugs was 13.44 g/mL according to crude drug） was observed by in vitro small intestine tension test in rats. The acetic acid writhing test was conducted in mice to evaluate the analgesic effects of macroporous resin efflux site and macroporous resin 90% ethanol elution site （the dosage of 2.4 g/kg according to crude drug）. The levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL- 1β）， prostaglandin E2 （PGE2） and cyclooxygenase-2 （COX-2） in serum of mice were detected. The serum prototype and metabolites of mice after intragastric administration of macroporous resin 90% ethanol elution site were identified by high performance liquid chromatogre-time-of-flight mass spectrometry. RESULTS In vitro experiment showed that 90% ethanol eluting part of macroporous resin represented the best antispasmodic effect， and the inhibitory rate of small intestine tension was significantly higher than macroporous resin efflux site of Shaoyao gancao decoction （P＜0.05） without statistical significance， compared with Shaoyao gancao decoction （P＞0.05）. In the acetic acid writhing experiment， compared with model group， the writhing times of mice in the macroporous resin 90% ethanol elution part group were reduced significantly （P＜0.05）， the writhing latency was prolonged significantly （P＜0.05）， and the levels of COX-2， IL-1β， PGE2 and TNF-α in serum were decreased significantly （P＜0.05）. Ten kinds of protoproducts including paeoniflorin and glycyrrhizic acid were identified from serum of mice， and twenty-two kinds of metabolites including hydroxylated glycyrrhizin and glucosylated liquiritin were identified. CONCLUSIONS The effective part of Shaoyao gancao decoction for relieving acute and chronic pain is 90% ethanol elution part prepared by macroporous resin from the ethyl acetate extract. Ten components， including glycyrrhetinic acid and paeoniflorin， may be the basis of its pharmacological substances.

Objective: Epidemiological studies on spinal cord tumors are rare, and studies on primary intramedullary tumors are even rarer. The incidence and survival of patients with primary intramedullary spinal cord tumors have not been well documented. We aimed to study the incidence and survival of patients with primary spinal cord malignant and borderline malignant tumors based on data from the Surveillance, Epidemiology, and End Results (SEER) database and provide information for revealing the epidemiology and exploring the prognosis of patients with primary intramedullary tumors. Methods: Patients in the SEER database with microscopically diagnosed malignant and borderline malignant primary spinal cord tumors from 2000 and 2019 were included in this study. We analyzed the distribution of patients according to the demographic and clinical characteristics. Then, we extracted the incidence rate and 5-year relative survival for the whole cohort and different subgroups of the cohort. Finally, multivariate Cox proportional hazards models were used to analyze the independent prognostic factors associated with overall survival. Results: A total of 5,211 patients with malignant and borderline malignant primary spinal cord tumors were included in this cohort study. Ependymoma, astrocytoma (including oligodendrogliomas and glioblastoma), lymphoma and hemangioblastoma were the most common pathological types. The age-adjusted incidence rates of primary spinal cord ependymoma was 0.18 per 100,000. The incidence rate for females was significantly lower than that for males. The incidence rate was highest in Caucasian. The incidence rate of ependymoma was significantly higher than that of other pathological types. The incidence of astrocytoma was highest among people aged 0–19 years, the incidence of ependymoma was highest among people aged 40–59 years, and the incidence of lymphoma was highest among people aged 60 years or older. The 5-year observed survival and relative survival rates for the whole cohort were 82.80% and 86.00%, respectively. Patients diagnosed with ependymoma had significantly better survival than their counterparts. We also found the impact of surgery and chemotherapy on the prognosis of patients with different tumors varies a lot. Conclusion We conducted a population-based analysis of malignant and borderline malignant primary spinal cord tumors with the aim of revealing the epidemiology and survival of patients with primary intramedullary spinal cord tumors. Despite some shortcomings, this study provides valuable information to help us better understand the epidemiological characteristics of primary intramedullary spinal cord tumors.

Objective:To explore the influence of deviation of the bolt in femoral neck system (FNS) on the short-term outcomes in young and middle-aged patients with displaced femoral neck fracture.Methods:A retrospective analysis was conducted of the 114 young and middle-aged patients with displaced femoral neck fracture who had been treated with FNS at Department of Orthopaedics, Suzhou Municipal Hospital from December 2019 to January 2023. Based on the postoperative measurements of the deviation of the bolt tip to the central axis of the femoral head and neck (W), the patients were divided into a central group (W≤20%) and a deviation group (W>20%). In the central group of 63 cases, there were 27 males and 36 females with a mean age of (46.4±8.0) years. In the deviation group of 51 cases, there were 20 males and 31 females with a mean age of (45.1±9.8) years. The 2 groups were compared in terms of weight-bearing time, fracture healing time, tip-apex distance, degree of femoral neck shortening, Harris Hip Score and EuroQol five-dimensional questionnaire-5L (EQ-5D-5L) utility value at the last follow-up, as well as complications and revision surgeries.Results:There was no statistically significant difference in the preoperative general information, auxiliary reduction or quality of fracture reduction between the 2 groups, showing comparability between groups ( P>0.05). There was no significant difference in the partial weight-bearing time between the 2 groups ( P>0.05). In the central group, the full weight-bearing time [15.0 (14.0, 16.0) weeks] and fracture healing time [14.0 (12.0, 15.0) weeks] were significantly shorter than those in the deviation group [16.0 (15.0, 19.0) weeks; 15.0 (13.0, 17.0) weeks], the tip-apex distance [(21.4±3.4) mm] was significantly shorter than that in the deviation group [(23.5±2.7) mm], the Harris Hip Score [(90.6±6.1) points] and EQ-5D-5L utility value [0.9 (0.8, 0.9)] at the last follow-up were significantly higher than those in the deviation group [(87.7±6.2) points; 0.9 (0.8, 0.9)], and the incidences of moderate and severe femoral neck shortening [25.4% (16/63)], avascular necrosis of the femoral head [0 (0/63)] and revision surgery [0 (0/63)] were significantly lower than those in the deviation group [66.7% (34/51), 7.8% (4/51), 9.8% (5/51)] (all P< 0.05). Conclusion:A closer positioning of the FNS bolt to the central axis of the femoral head and neck favors satisfactory short-term outcomes and a lower revision surgery rate in young and middle-aged patients with displaced femoral neck fracture.

Objective:To evaluate the nutritional status of vitamin A(VitA)in breast milk and its influencing factors among lactating women in the Weihai,Yueyang,and Baotou of China.Methods:From May to July 2014,403 lactating mothers at(42±7)d postpartum were recruited from three Chinese cities,Weihai in Shandong Province,Yueyang in Hunan Province,and Baotou in Inner Mongolia.Basic information of lactating women and newborns and fish intake information of the lactating women in the last month were collected.The concentration of retinol in breast milk was collected and measured using high-performance liquid chromatography to determine the levels of VitA.According to the breast milk retinol concentration,the nutritional status of breast milk VitA among the lactating women was divi-ded into deficiency(＜1.05 μmol/L)and sufficient(≥1.05 μmol/L).The multivariate quantile regres-sion was used to calculate the adjusted breast milk retinol concentrations.The Kruskal-Wallis H test and the Mann-Whitney U test were used to test the difference of breast milk retinol concentration according to the characteristics of the lactating women.The Logistic regression was used to analyze the effect of char-acteristics of lactating women on breast milk VitA deficiency.Results:The M(P25,P75)of breast milk retinol concentration among the Chinese lactating women was 1.15(0.83,1.49)μmol/L.Multivariate analysis showed that the adjusted breast milk retinol concentration was related to the regions,maternal age,ethnicity,education levels,body mass index(BMI),parity,gestational age,delivery modes,breastfeeding practice,fish intake and birth weight of the infants.The prevalence of VitA deficiency in breast milk among all the lactating women was 41.9％.In Weihai,Yueyang,and Baotou,the preva-lence rates were 34.8％,39.6％,and 51.5％,respectively.Compared with the women in Weihai,the adjusted OR for breast milk VitA deficiency among the women in Baotou was 1.75(95％CI:1.05-2.92).Compared with the women having college and above education,the adjusted OR for breast milk VitA deficiency among those having junior high school and below education were 2.16(95％CI:1.10-4.24).Compared with women with low fish intake,the adjusted OR for breast milk VitA defi-ciency among those with high fish intake were 0.55(95％CI:0.36-0.84).Conclusion:The preva-lence of breast milk VitA deficiency among the Chinese lactating women was 41.9％,suggesting that breast milk VitA deficiency in lactating women and inadequate VitA intake for infants were common in China.The women in Baotou,low educational status and low fish intake increased the risk of breast milk VitA deficiency,suggesting that attention should be paid to the nutritional status of lactating women in underdeveloped regions such as inland region,and education for health should be enhanced and food con-taining VitA such as fish intake should be increased.

OBJECTIVE To explore the lipid-regulating mechanism of the classic prescription Zexie Decoction on hyperlipidemia model mice.METHODS ELISA method was used to detect the four blood lipid indexes,liver function indicators and cholesterol acyltransferase levels in serum.HE and Oil Red O staining were used to determine the pathology of liver tissue.Network pharmacology was used to predict the lipid-lowering related targets of Zexie Decoction,and the GO function and KEGG pathway enrichment analyses of the intersection targets were realized.PCR chip technology was used to detect the target genes for network pharmacology screening,and qPCR and Western blot were used to detect gene and protein expression levels.RESULTS Zexie Decoction significantly regula-ted the four blood lipid indexes in hyperlipidemia model mice,improved the increase in liver damage indicators caused by high lipids,and had a reverse regulatory effect on the key enzymes HMGR and CYP7A1 of lipid metabolism and the lipid transporters ABCA1 and Apo-A1 in liver tissue.HE and Oil Red O staining showed that Zexie Decoction improved the pathological morphology of liver tissue,reduced lipid deposition in liver tissue,and significantly decreased the positive area ratio(P<0.01).The PCR chip obtained 44 re-verse-regulated genes,GO functional enrichment analysis obtained 266 entries,and KEGG pathway enrichment analysis screened 99 signaling pathways.The results of qPCR and Western blot showed that Zexie Decoction significantly downregulated the expression of PIK3CG,AKT1,and IL-6 genes(P<0.05,P<0.01),upregulated the expression of ABCG1 gene(P<0.05),downregulated PI3Kinase p110β,p-AKT(Ser473)and SREBP-1c protein expression levels(P<0.01),and reversely regulated miR21-5p(P<0.01).CONCLUSION Zexie Decoction has a significant regulatory effect on lipid metabolism in hyperlipidemia model mice and can improve liver damage caused by hyperlipidemia.Its lipid-regulating effect may be related to regulating cholesterol metabolism and transport in the body,and is closely linked to the miR21/PI3K-Akt/SREBP pathway.The lipid-regulating effect of the whole formula of Zexie Decoction is better than that of a single herb.
