Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To evaluate the efficacy and long-term outcomes of fludarabine, cyclophosphamide, and rituximab (FCR) in treatment-na?ve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) .Methods:Clinical data from 68 CLL/SLL patients treated with FCR at Jiangsu Province Hospital (August 2008–May 2021) were retrospectively analyzed to assess efficacy, safety, and survival outcomes.Results:Among 68 patients [46 males, 22 females; median age 55 (47, 60) years], 13.1% (8/61) had a complex karyotype, 32.3% (20/62) had immunoglobulin heavy variable region mutated (IGHV-M) type, 6.6% (4/61) had del (17p), and 14.8% (8/54) had del (11q). Patients received a median of 6 (4, 6) FCR cycles. The overall response rate was 88.2% (60/68), including 47.0% (32/68) complete remissions. Over a median follow-up of 82 (59, 98) months, 66.2% (45/68) experienced disease progression. Median progression-free survival was 56 (21, 123) months, while median overall survival was not reached. The 5- and 10-year PFS rates were 42.6% (95% CI: 31.9–56.8% ) and 28.7% (95% CI: 19.0–43.4% ), respectively. Poor PFS was associated with del (17p) ( HR=5.04, 95% CI: 1.72–14.74, P=0.003), del (11q) ( HR=5.27, 95% CI: 2.11–13.15, P<0.001), IGHV unmutated (IGHV-UM) ( HR=4.11, 95% CI: 1.72–9.79, P=0.001), complex karyotype (CK) ( HR=3.53, 95% CI: 1.58–7.85, P=0.002), β 2-microglobulin >3.5 mg/L ( HR=2.87, 95% CI: 1.37–6.01, P=0.005). In multivariate analysis, IGHV-UM remained an independent predictor of PFS ( HR=8.63, 95% CI: 1.09–68.40, P=0.042). Sixteen patients with IGHV-M and lacking del (17p) or CK had a median PFS of 123 (58,123) months and a 5-year PFS rate of 70.7% (95% CI: 49.7–99.1% ), reaching a plateau after 5 years with no recurrences by 10 years. Common grade 3–4 adverse events included hematologic toxicity (44.1%, 30/68), infection (36.7%, 25/68), and liver dysfunction (4.4%, 3/68). Among 25 patients receiving single-agent BTK inhibitors after FCR progression, median follow-up was 45 (26, 64) months; 36% (9/25) experienced disease progression, with a median PFS time of 55 (27, 55) months. Conclusion:First-line FCR provides durable long-term benefits for patients with IGHV-M CLL without del (17p) or CK.

This study aims to explore the protective effect of Chaihu Jia Longgu Muli Decoction on rats with heart failure after myocardial infarction, and to clarify its possible mechanisms, providing a new basis for basic research on the mechanism of classic Chinese medicinal formula-mediated inflammatory response in preventing and treating heart failure induced by apoptosis after myocardial infarction. A heart failure model after myocardial infarction was established in rats by coronary artery ligation. The rats were divided into sham group, model group, and low, medium, and high-dose groups of Chaihu Jia Longgu Muli Decoction, with 10 rats in each group. The low-dose, medium-dose, and high-dose groups of Chaihu Jia Longgu Muli Decoction were given 6.3, 12.6, and 25.2 g·kg~(-1) doses by gavage, respectively. The sham group and model group were given an equal volume of distilled water by gavage once daily for four consecutive weeks. Cardiac function was assessed using color Doppler echocardiography. Myocardial pathology was detected by hematoxylin-eosin(HE) staining, apoptosis was measured by TUNEL assay, and mitophagy was observed by transmission electron microscopy. The levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, and N-terminal pro-B-type natriuretic peptide(NT-proBNP) in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of apoptosis-related proteins B-cell lymphoma 2(Bcl-2), Bcl-2-associated X protein(Bax), and cleaved caspase-3 was detected by Western blot. Additionally, the expression of phosphorylated nuclear transcription factor-κB(NF-κB) p65(p-NF-κB p65)(upstream) and nuclear factor kappa B inhibitor alpha(IκBα)(downstream) in the NF-κB signaling pathway was assessed by Western blot. The results showed that compared with the sham group, left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) in the model group were significantly reduced, while left ventricular end diastolic diameter(LVEDD) and left ventricular end systolic diameter(LVESD) increased significantly. Myocardial tissue damage was severe, with widened intercellular spaces and disorganized cell arrangement. The apoptosis rate was increased, and mitochondria were enlarged with increased vacuoles. Levels of TNF-α, IL-1β, and NT-proBNP were elevated, indicating an obvious inflammatory response. The expression of pro-apoptotic factors Bax and cleaved caspase-3 increased, while the anti-apoptotic factor Bcl-2 decreased. The expression of p-NF-κB p65 was upregulated, and the expression of IκBα was downregulated. In contrast, the Chaihu Jia Longgu Muli Decoction groups showed significantly improved of LVEF, LVFS and decreased LVEDD, LVESD compared to the model group. Myocardial tissue damage was alleviated, and intercellular spaces were reduced. The apoptosis rate decreased, mitochondrial volume decreased, and the levels of TNF-α, IL-1β, and NT-proBNP were lower. The expression of pro-apoptotic factors Bax and cleaved caspase-3 decreased, while the expression of the anti-apoptotic factor Bcl-2 increased. Additionally, the expression of p-NF-κB p65 decreased, while IκBα expression increased. In summary, this experimental study shows that Chaihu Jia Longgu Muli Decoction can reduce the inflammatory response and apoptosis rate in rats with heart failure after myocardial infarction, which may be related to the regulation of the IκBα/NF-κB signaling pathway.

Patients received a median of 6 (4, 6) FCR cycles. The overall response rate was 88.2% (60/68), including 47.0% (32/68) complete remissions. Over a median follow-up of 82 (59, 98) months, 66.2% (45/68) experienced disease progression. Median progression-free survival was 56 (21, 123) months, while median overall survival was not reached. The 5- and 10-year PFS rates were 42.6% (95% CI: 31.9–56.8% ) and 28.7% (95% CI: 19.0–43.4% ), respectively. Poor PFS was associated with del (17p) ( HR=5.04, 95% CI: 1.72–14.74, P=0.003), del (11q) ( HR=5.27, 95% CI: 2.11–13.15, P<0.001), IGHV unmutated (IGHV-UM) ( HR=4.11, 95% CI: 1.72–9.79, P=0.001), complex karyotype (CK) ( HR=3.53, 95% CI: 1.58–7.85, P=0.002), β 2-microglobulin >3.5 mg/L ( HR=2.87, 95% CI: 1.37–6.01, P=0.005). In multivariate analysis, IGHV-UM remained an independent predictor of PFS ( HR=8.63, 95% CI: 1.09–68.40, P=0.042). Sixteen patients with IGHV-M and lacking del (17p) or CK had a median PFS of 123 (58,123) months and a 5-year PFS rate of 70.7% (95% CI: 49.7–99.1% ), reaching a plateau after 5 years with no recurrences by 10 years. Common grade 3–4 adverse events included hematologic toxicity (44.1%, 30/68), infection (36.7%, 25/68), and liver dysfunction (4.4%, 3/68). Among 25 patients receiving single-agent BTK inhibitors after FCR progression, median follow-up was 45 (26, 64) months; 36% (9/25) experienced disease progression, with a median PFS time of 55 (27, 55) months. Conclusion:First-line FCR provides durable long-term benefits for patients with IGHV-M CLL without del (17p) or CK.

Objective:To investigate the vaccination status, characteristics and prognosis of patients suffering from a combination of COVID-19 and chronic lymphocytic anemia (CLL) in China.Methods:Clinical data of 328 patients with chronic lymphocytic leukemia (CLL) who were first diagnosed with COVID-19 and treated in the Department of Hematology of Jiangsu Provincial People’s Hospital between November 2022 and February 2023 were retrospectively analyzed. Univariate and multivariate analysis of data of patients with severe/critical COVID-19 were conducted by applying the binary logistic regression model.Results:The median age of the CLL patients was 60 (24-87) years. 23.5% (77/328) of these patients suffered from severe/critical COVID-19 infection. Univariate analysis of the data demonstrated that a combination of factors including age >67 years ( OR=2.15, 95% CI 1.24- 3.73, P=0.006), diabetes ( OR=2.09, 95% CI 1.05-4.20, P=0.037), chronic hepatitis B ( OR=2.91, 95% CI 1.30-6.51, P=0.010), CLL progressive ( OR=3.79, 95% CI 1.57-9.15, P=0.003) and CD20 antibody-based treatments within three months prior to the COVID-19 infection ( OR=2.79, 95% CI 1.35-5.77, P=0.006) were the risk factors for severe/critical COVID-19. According to the multivariate analysis, CLL progressive ( OR=2.98, 95% CI 1.10-8.10, P=0.033) was an independent risk factor for severe/critical COVID-19 and administration of the BTK (Bruton tyrosine kinase) inhibitor monotherapy might exert a protective effect and influence a positive outcome of the COVID-19 infection ( OR=0.38, 95% CI 0.16-0.90, P=0.028). Among the 242 patients who were followed up until October 2023, 9.1% (22/242) had multiple subsequent COVID-19 infections (≥3), and 2.1% (5/242) had persistent COVID-19 infections (patients with persistent positive test for the SARS-CoV-2 antigen testing until missing follow-up for any reason). The peak value of the anti-SARS-CoV-2-IgG titres was observed between three and four months post symptom onset (median: 3.511 S/CO vs 1.047 S/CO, P<0.05). The levels of immunoglobulin A gradually decreased following infection with COVID-19, and its trough levels were attained between two to four weeks post infection (median: 0.30 g/L vs 0.74 g/L, P<0.05). According to this study the mortality of patients suffering from a combination of COVID-19 infection and CLL was 2.7% (9/328), and the main reason for their death was respiratory failure and heart failure. Conclusions:A low rate of COVID-19 vaccination and a high rate of severe/critical COVID-19 infection was observed in the CLL patients. CLL progressive was associated with severe/critical COVID-19. Anti-CD20-based treatments received within the past three months might be a risk factor for exacerbation of COVID-19 infection, whereas a monotherapy with BTK inhibitors exert a protective effect and improve outcome of COVID-19 infection.

Aim To investigate the effects of hedysar-um polybotrys polysacchcaide(HPS)on gastric muco-sal inflammation of diabetic gastroparesis(DGP)rats and its possible mechanism.Methods A total of 62 male Wistar rats were randomly divided into the control group(12)and the modeling group(50).Except for the control group,the remaining rats were given multi-ple intraperitoneal injections of streptozotocin(25 mg ·kg-1 for three consecutive days)and irregular feed-ing of high-sugar and high-fat diet to replicate DGP model.The model rats were randomly divided into the model group(intragastatically purified water),low,medium and high dose HPS groups(50,100,200 mg ·kg-1·d-1)and the metformin group(90 mg· kg-1·d-1),respectively,and the control group was intragastrically treated with equal volume of purified water once a day for eight weeks.The pathological morphology of gastric mucosa was observed by HE stai-ning;the contents of TNF-α,IL-6,GAS and MTL in gastric mucosa were detected by ELISA.The expres-sion of JAK2 and STAT3mRNA in gastric mucosa was detected by RT-PCR.The levels of JAK2 and STAT3 proteins and their phosphorylation in gastric mucosa were detected by Western blot.Results Compared with the control group,the gastric mucosa of the model group showed a large number of inflammatory cells in-filtrated by HE staining.The contents of TNF-α and IL-6 significantly increased(P＜0.01),while the contents of GAS and MTL significantly decreased(P＜0.01).The mRNA expressions of JAK2 and STAT3 significantly increased(P＜0.05).p-JAK2and p-STAT3 significantly increased(P＜0.01).Compared with the model group,gastric mucosal inflammation was improved in each administration group.The con-tents of TNF-α and IL-6 decreased significantly,while the contents of GAS and MTL increased significantly.The mRNA expressions of JAK2 and STAT3 were sig-nificantly reduced.The expressions of p-JAK2 and p-STAT3 significantly decreased(P＜0.05).Conclu-sions HPS can improve gastric mucosal inflammation and repair gastric mucosal damage in rats,and its mechanism may be related to the regulation of JAK2/STAT3 signaling pathway.
