OBJECTIVE To investigate the improvement mechanism of hyperoside （HYP） on non-alcoholic fatty liver disease （NAFLD）. METHODS Male C57BL/6 mice were randomly divided into normal （NFD） group， model （HFD） group and HYP group， with 8 mice in each group. Except for NFD group， the mice in other groups were fed with HF60 high-fat diet to establish NAFLD model； HYP group was simultaneously given HYP 100 mg/kg intragastrically every day， for 16 consecutive weeks. The body weight and liver weight of mice in each group were recorded 16 h after the last medication； the histopathological changes and lipid accumulation in the liver were observed， and the contents of triglyceride （TAG） in liver tissue and serum contents of TAG， aspartate transaminase （AST） and alanine transaminase （ALT） were measured； LC-MS/MS method was adopted to detect lipid changes in the liver tissue of mice for lipidomics analysis， and protein expressions of lipid synthesis-associated proteins peroxisome proliferator-activated receptor α （PPARα） were also tested. Human hepatocellular carcinoma cell line HepG2 was divided into normal control group， model group， HYP low-concentration group （50 μmol/L）， HYP high-concentration group （100 μmol/L）， HYP low-concentration+GW6471 （PPARαinhibitor） group， and HYP high-concentration+GW6471 group. Except for normal control group， the remaining cells were induced with oleic acid and palmitic acid to establish a high-fat cell model. The accumulation of lipid droplets in each group of cells was observed， and the TAG content was detected. RESULTS Compared with HFD group， HYP group exhibited significant reductions in liver fat vacuoles， lipid accumulation， liver weight， and TAG content in liver tissue， as well as serum contents of ALT， AST and TAG （P＜0.05）. Additionally， the expression of PPARα protein in liver tissue was significantly increased （P＜0.05）， and the pathological morphological changes associated with NAFLD were alleviated. Lipidomic analysis revealed that HYP significantly reduced the levels of TAG， diacylglycerol and other lipids in the liver. Compared with model group， cellular lipid droplet accumulation and TAG content decreased significantly in HYP low- and high-concentration groups （P＜0.05）； GW6471 could significantly reverse the improvement effect of HYP on above indicators （P＜0.05）. CONCLUSIONS HYP can effectively ameliorate NAFLD induced by a high-fat diet in mice， and the mechanism may be related to the activation of PPARα to regulate hepatic lipid synthesis.

OBJECTIVE To evaluate the contents of characteristic components in Hugan qingzhi formula （HGQZ） decoction and formulated granules and the pharmacodynamic consistency of them on high-fat diet-induced non-alcoholic fatty liver disease （NAFLD） model mice， and explore their potential underlying mechanisms of action. METHODS Liquid chromatography-tandem mass spectrometry was used to analyze and compare the contents of six characteristic components in HGQZ decoction and formulated granules. Male C57BL/6 mice were randomly divided into normal control group， model group， HGQZ decoction low- dose and high-dose groups （13， 26 g/kg， calculated by crude drugs）， and HGQZ formulated granules low-dose and high-dose groups （13， 26 g/kg， calculated by crude drugs）， with 6 mice in each group. Except for the normal control group， which was fed a regular diet， the mice in the other groups were fed a high-fat diet for 20 weeks to establish the NAFLD model； at the same time， the mice in each group were gavaged with the corresponding drugs/water once. The fasting blood glucose （FBG） levels， glucose and insulin tolerance， body weight， liver index， white adipose Δ 基金项目 国家自然科学基金项目（No.82074078）；广东省基础 tissue index， brown adipose tissue index， as well as lipid levels （total cholesterol， triglycerides） and liver function indicators （aspartate transaminase， alanine transaminase） were measured. Additionally， histopathological changes and lipid accumulation in liver tissues were observed. The serum samples of mice in the model group， HGQZ decoction high-dose group and HGQZ formulated granules high-dose group were taken for metabolomics analysis， and validation of the underlying mechanisms was conducted. RESULTS There were no statistically significant differences in the contents of ginsenoside Rb1， typhaneoside， isorhamnetin-3-O-neohesperidoside， hyperoside， nuciferine， and 23-acetylalismol B between HGQZ decoction and HGQZ formulated granules （P＞0.05）. Compared with the model group， the hepatic histopathological changes in mice were alleviated in both the HGQZ decoction group and all dose groups of HGQZ formulated granules. Inflammatory cell infiltration and lipid vacuoles were reduced. Additionally， there was a general improvement in FBG levels， glucose tolerance， insulin tolerance， body weight， liver index， white/brown adipose tissue index， lipid levels， and liver function indicators （P＜0.05）. However， no statistically significant differences were observed between these treatment groups （P＞0.05）. There were 234 and 136 differentially expressed serum metabolites identified in the model group versus HGQZ decoction high-dose group， and model group versus HGQZ formulated granules high-dose group， respectively. After taking the intersection， 65 common differentially expressed metabolites were obtained， which were enriched in metabolic pathways such as purine metabolism and tricarboxylic acid cycle metabolism. Among these， the content of citrate in the model group was significantly lower than that in both the HGQZ decoction group and HGQZ formulated granules high-dose group （P＜0.05）. Both high-dose HGQZ decoction and formulated granules could significantly elevate the phosphorylation levels of AMP-activated protein kinase （AMPK） （P＜0.05）. CONCLUSIONS HGQZ decoction and formulated granules contain comparable amounts of characteristic components， and both exhibit equivalent efficacy on NAFLD model mice. The anti-NAFLD effects of HGQZ are associated with the activation of the AMPK energy metabolism pathway.

Sepsis is a potentially fatal condition characterized by the failure of one or more organs due to a disordered host response to infection. The development of sepsis is closely linked to immune dysfunction. As a result, immunotherapy has gained traction as a promising approach to sepsis treatment, as it holds the potential to reverse immunosuppression and restore immune balance, thereby improving the prognosis of septic patients. However, due to the highly heterogeneous nature of sepsis, it is crucial to carefully select the appropriate patient population for immunotherapy. This review summarizes the current and evolved treatments for sepsis-induced immunosuppression to enhance clinicians' understanding and practical application of immunotherapy in the management of sepsis.

OBJECTIVE To study the effects of bergapten in the treatment of liver fibrosis and its mechanism based on serum metabolomics. METHODS Forty mice were divided into normal control group （0.5% carboxymethyl cellulose sodium solution）， model group （0.5% carboxymethyl cellulose sodium solution）， and BP low-dose and high-dose groups （50， 100 mg/kg）， with 10 mice in each group. Except for the normal control group， the other three groups were all treated with carbon tetrachloride to induce liver fibrosis model； they were given relevant medicine/solution intragastrically， once a day， for consecutive 8 weeks. After the last medication， the levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in serum were detected， and liver pathological changes were observed； the expressions of α-smooth muscle actin （α-SMA） and Collagen Ⅰ were detected in liver tissue； the serum of the mice was collected for metabolomics analysis. RESULTS Compared with the model group， serum levels of ALT and AST and protein expressions of α-SMA and Collagen Ⅰ in liver tissue were decreased significantly in BP high-dose and low-dose groups （P＜0.05）， while liver fibrosis was improved significantly. Meanwhile， metabolomics analyses showed that there were a total of 175 serum differential metabolites in the BP high-dose group and model group， of which 18 substances were upregulated and 157 substances were downregulated； the main metabolic pathways involved in bergapten intervention were pyrimidine metabolism， butanoate metabolism， fatty acid synthesis， tyrosine metabolism， β-alanine metabolism， nicotinic acid and nicotinamide metabolism， glutathione metabolism， etc. CONCLUSIONS BP is effective in the treatment of liver fibrosis by regulating pyrimidine metabolism， butanoate metabolism， glutathione metabolism and so on in rats with liver fibrosis.

Objective:To evaluate the surgery combined chemotherapy and radiation in locally advanced neuroendocrine carcinoma of the cervix (NECC) .Methods:This is a single-center retrospective cohort study. Locally advanced NECC patients admitted to Peking Union Medical College Hospital, Chinese Acadmy of Medical Sciences from January 2011 to April 2022 were enrolled. They were divided into concurrent chemoradiotherapy group, and surgery combined with chemotherapy and radiation group. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate.Results:(1) Forty-six cases were included, 22 in concurrent chemoradiotherapy group, 24 in surgery combined chemotherapy and radiation group. With 16 patients (35%, 16/46) received neoadjuvant chemotherapy (NACT), the NACT effective rate was 15/16. (2) The median follow-up time was 27.5 months (range: 10-106 months), with 26 (57%, 26/46) experienced recurrences. There were 4 (9%, 4/46) pelvic recurrences and 25 (54%, 25/46) distant recurrences, and 3 (7%, 3/46) both pelvic and distant recurrences. Compared with concurrent chemoradiotherapy group, surgery combined chemotherapy and radiation group had lower pelvic recurrence rate [14% (3/22) vs 4% (1/24); χ2=1.296, P=0.255] but without statistic difference. Both groups had similar distant recurrence rate [55% (12/22) vs 54% (13/24); χ2=0.001, P=0.979] and overall recurrence rate [59% (13/22) vs 54% (13/24); χ2=0.113, P=0.736]. (3) During the follow-up period, 22 cases (48%, 22/46) died, with 11 cases (50%, 11/22) in concurrent chemoradiotherapy group and 11 cases (46%, 11/24) in surgery combined chemotherapy and radiation group, without significant difference ( χ2=0.080, P=0.777). The postoperative 3-year and 5-year OS rates were 62.3% and 36.9%. Compared with concurrent chemoradiotherapy group, the patients in surgery combined chemotherapy and radiation group showed an extended trend in PFS (17.0 vs 32.0 months) and OS (37.0 vs 50.0 months) but without statistic differences ( P=0.287, P=0.125). Both groups had similar 3-year OS rate (54.2% vs 69.9%; P=0.138) and 5-year OS rate (36.1% vs 38.8%; P=0.217). Conclusions:Our study supports the multi-modality treatment strategy (including surgery, chemotherapy and radiation) as an important component in the treatment of locally advanced NECC. The combination of surgery, chemotherapy and radiation seems to have advantages in the treatment of locally advanced NECC, but needs to be confirmed by further multicenter studies.

Depression syndromes(anxiety and depression), as typical psychological disorders, often coexist with and mutually influence coronary heart disease(CHD). They constitute a psycho-cardiology disease involving both the blood vessels of the heart and the spirit of the heart. Based on the theory of "coexistence of diseases and depression syndromes", it was proposed that CHD and depression syndromes coexisted independently and were causally related. The factors of depression syndromes go through the entire course of CHD and have different causal relationships at different stages, leading to a pathogenic process of "depression causing disease" or "disease causing depression". In the chronic latent period, phlegm predominates, with depression leading to the production of phlegm. Phlegm accumulation and Qi stagnation initiate a mutual damage process of psycho-cardiology, marking the onset of the disease. In the pathological development period, blood stasis becomes predominant. Depression leads to blood stasis, which further obstructs Qi circulation, accelerating disease progression. In the acute attack period, toxicity becomes crucial. Depression transforms into toxicity, damaging Qi and blood, disturbing the balance of the mind, and inducing a sudden and severe exacerbation of the disease. Based on this, the approach of treating phlegm and depression together, treating blood stasis and depression together, and treating toxicity and depression together by stages was established. Research has found that this approach can simultaneously improve organic damage and emotional disorders, and also has a regulating effect on micro-level syndrome indicators, achieving harmonization of psycho-cardiology in the treatment.

OBJECTIVE To study the effects of isoliquiritigenin （ISL） regulating gut microbiota and repairing gut barrier function in model mice with non-alcoholic fatty liver disease （NAFLD）， and to clarify its mechanism for improving NAFLD. METHODS Thirty male C57BL/6J mice were randomly divided into the normal （ultrapure water）， model group （ultrapure water）， ISL group （100 mg/kg）， with 10 mice in each group. Model group and ISL group were fed with high-fat diet for 19 weeks to establish NAFLD model； at the same time， the mice were given relevant medicine/ultrapure water intragastrically. The changes of body weight in mice were recorded， and liver index， white fat index and brown fat index were calculated. The pathological changes of liver tissue and colon tissue as well as lipid accumulation were observed in mice. The levels of total cholesterol （TC）， triglyceride （TG）， aspartate aminotransferase （AST） and alanine aminotransferase （ALT） E-mail：xiangshj3@mail.sysu.edu.cn in serum or liver were measured； the serum levels of interleukin-6 （IL-6）， IL-1β and tumor necrosis factor-α （TNF-α） and the levels of IL-6， IL-1β and TNF-α mRNA expression in liver tissue were detected. Fecal samples underwent 16S rDNA sequencing analysis， and the effects of ISL on gut microbiota structure of mice were investigated. The expressions of gut mucosal barrier-related proteins （Claudin-4， Occludin and ZO-1） were determined in the colon tissue of mice. RESULTS Compared with model group， the body weight， liver index， the levels of TC in liver tissue and serum， the levels of AST and ALT in serum， the levels of IL-6， IL-1β and TNF-α in serum， and the mRNA expression of TNF-α in liver tissue were all decreased significantly in ISL group， while brown fat index was increased significantly. The inflammation and damage of liver tissue were significantly improved， and the NAFLD activity score and the proportion of lipid staining area were significantly reduced （P＜0.05）. ISL could significantly up-regulate the relative abundance of beneficial microbiota （norank_f_Muribaculaceae， Odoribacter， Ruminiclostridium， etc.） and the expressions of intestinal barrier function- related proteins， but could significantly down-regulate the relative abundance of harmful bacteria （Desulfovibrio， norank_f_Lachnospiraceae， unclassified_p_Firmicutes）， and could repair intestinal barrier. CONCLUSIONS ISL could significantly delay the progress of NAFLD， the mechanism of which may be associated with regulating gut microbiota and improving gut barrier function.

Objective: To evaluate the effect of postoperative radiotherapy and high-risk pathological factors on the prognosis of early-stage neuroendocrine carcinoma of cervix (NECC). Methods: A single-center retrospective cohort study of early-stage NECC in Peking Union Medical College Hospital from January 2011 to April 2022 were enrolled. The patients were treated with radical hysterectomy±adjuvant treatment. They were divided into postoperative non-radiation group and postoperative radiation group. The possible postoperative recurrence risk factors identified by univariate analysis were assessed using multivariate logistic regression. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate. Results: (1) Sixty-two cases were included in the study, including 33 cases in postoperative non-radiation group and 29 cases in postoperative radiation group. (2) The median follow-up time was 37 months (ranged 12-116 months), with 23 cases (37%) experienced recurrences. There were 7 cases (11%) pelvic recurrences and 20 cases (32%) distant recurrences, in which including 4 cases (6%) both pelvic and distant recurrences. Compared with postoperative non-radiation group, the postoperative radiation group had a lower pelvic recurrence rate (18% vs 3%; P=0.074) but without statistic difference, a slightly elevated distant recurrence rate (24% vs 41%; P=0.150) and overall recurrence rate (33% vs 41%; P=0.513) without statistically significances. Univariate analysis showed that lymph-vascular space invasion and the depth of cervical stromal invasion≥1/2 were risk factors for postoperative recurrence (all P<0.05). Multivariate analysis showed lymph-vascular space invasion was an independent predictor for postoperative recurrence (OR=23.03, 95%CI: 3.55-149.39, P=0.001). (3) During the follow-up period, 18 cases (29%, 18/62) died with tumor, with 10 cases (30%, 10/33) in postoperative non-radiation group and 8 cases (28%, 8/29) in postoperative radiation group, without significant difference (P=0.814). The postoperative 3-year and 5-year survival rate was 79.2%, 60.8%. The depth of cervical stromal invasion≥1/2 was more common in postoperative radiation group (27% vs 64%; P=0.011), and postoperative radiation in such patients showed an extended trend in PFS (32.3 vs 53.9 months) and OS (39.4 vs 73.4 months) but without statistic differences (P=0.704, P=0.371). Compared with postoperative non-radiation group, the postoperative radiation did not improve PFS (54.5 vs 37.3 months; P=0.860) and OS (56.2 vs 62.4 months; P=0.550) in patients with lymph-vascular space invasion. Conclusions: Postoperative radiation in early-stage NECC patients has a trend to reduce pelvic recurrence but not appear to decrease distant recurrence and overall recurrence, and has not improved mortality. For patients with the depth of cervical stromal invasion≥1/2, postoperative radiation has a trend of prolonging OS and PFS but without statistic difference. Lymph-vascular space invasion is an independent predictor for postoperative recurrence, but postoperative radiation in such patients does not seem to have any survival benefits.
