Objective: To evaluate the efficacy and safety of ruxolitinib combined with low-dose hormone for patients with acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Thirty patients with aGVHD after allo-HSCT admitted to the Department of Hematology of the General Hospital of Western Theater Command from November 2021 to November 2024 were retrospectively analyzed. All patients were treated with low-dose hormone (methylprednisolone 0.3-1 mg kg -d ) combined with ruxolitinib 5-10 mg d . The efficacy and adverse reactions were observed during the follow-up period to analyze the survival outcomes of the patients. Results: A total of 30 patients with aGVHD after allo-HSCT were included in this study, consisting of 15 (50%) males and 15 (50%) females with a median age of 34 year-old (ranging from 14 to 62). Classification by disease type: there were 18 cases of acute myeloid leukemia, 4 cases of acute lymphoblastic leukemia, 4 cases of aplastic anemia, and 4 cases of myelodysplastic syndrome. Classification by aGVHD severity: there were 27 cases (90%) of Ⅱ-Ⅳ degree aGVHD and 11 cases (36.7%) of Ⅲ-Ⅳ degree aGVHD. Ruxolitinib in combination with low-dose glucocorticoid treatment yield responses in 28 (93.3%) patients, of which 27 (90%) achieved complete remission (CR), while 1 (3.3%) showed partial remission (PR). One patient (3.3%) had no response (NR), and 1 patient (3.3%) exhibited progressed disease (PD). Overall survival (OS) at 1 year of transplantation was 73.9% (95%CI 49.5% to 87.7%), progression-free survival (PFS) was 93.3% (95%CI 75.9% to 98.3%), non-relapse mortality (NRM) was 20.6% (95%CI 7.9% to 47.4%), and median survival time was 27.6 months. Conclusion: Ruxolitinib combined with low-dose hormones is safe and effective in the treatment of aGVHD after allo-HSCT.

Background As one of the key populations in the prevention and treatment of iodine deficiency disorders, it is important to continuously monitor the iodine nutritional level of school-age children. The current reference interval for thyroid volume in China is based on age only, without taking into account differences in individual developmental levels, and the distribution of thyroid volume may vary regionally due to economic, demographic, and environmental factors. The current reference cut-off points for thyroid volume proposed by the World Health Organization are not based on the Chinese population. Objective To understand the iodine nutritional status and distribution of thyroid volume (Tvol) among children aged 8-10 years in Huangpu District, Shanghai, China, to identify impact factors of Tvol, and to propose a reference range upper limit for local thyroid health surveillance, so as to provide a basis for goiter control and prevention. Methods Six hundred children aged 8-10 years in Huangpu District were recruited in 2017, 2020, and 2023, and body height, weight, thyroid volume, urinary iodine, and iodine content of household edible salt were determined. A multilevel model was constructed using population density and area as regional variables, and age, body surface area (BSA), and body mass index (BMI) as potential impact factors for at the individual level, to assess their effects on thyroid volume. Quantile regression of thyroid volume was performed, and the 98th percentile (P₉₈) of thyroid volume was predicted based on age and BSA. Results The iodized salt coverage in the households of surveyed children in 2017, 2020, and 2023 was 72.0%, 57.0%, and 48.0%, respectively, and the iodized salt coverage decreased by year (χ²=24.31, P<0.001). The urinary iodine level of children in 2017 was higher than that in 2020 and 2023 (χ²=18.77, P<0.001). The Tvol medians of children in 2017, 2020, and 2023 were 2.29, 2.49, and 2.97 mL, respectively, and the Tvol increased by year (χ²=60.04, P<0.001). The proportion of goiter was higher in children in 2023 than in 2017 and 2020 (χ²=6.57, P<0.05). Sex differences were not statistically significant for urinary iodine levels, thyroid volume, and goiter. The median Tvol was 2.26, 2.58, and 2.76 mL in children of 8, 9, and 10 years old respectively, and the Tvol increased with age (χ²=49.02, P <0.001). Tvol was positively correlated with age, BSA, and BMI with correlation coefficients of 0.2846, 0.3723, and 0.2950, respectively. The final quantile regression model showed that the strongest effect of BSA was associated with the 98th percentile of Tvol. Multilevel models considering population density or area as regional variables failed to achieve convergence. Conclusion To establish the upper limit of the reference interval for thyroid volume of healthy children in Huangpu District, the effects of age and BSA should be considered at the individual level, and the upper limit of the normal interval for goiter screening is suggested to be the 98th percentile value of BSA at the same age. In addition, the adaptability of population density and regional area as indicators of regional aggregation of thyroid volume distribution still needs to be further explored.

Objective To determine the effects of heated iodophor disinfection on intraoperative body temperature and bleeding in elderly patients undergoing radical mastectomy.Methods A total of 78 elderly patients who underwent unilateral radical mastectomy in Suqian Hospital of Jiangsu Provincial People's Hospital from September 2022 to August 2024 were selected as the study subjects,and they were randomly divided into the control group and the observation group,with 39 cases in each group.The control group and the observation group were disinfected with iodophor at temperature of 23℃and heated to 37℃before surgery,respectively.The qualified skin disinfection,incision infection,body temperature,adverse reactions during the recovery period,intraoperative bleeding volume,postoperative drainage bleeding volume,and hemoglobin levels of patients of the two groups were compared.Results There was no statistically significant difference in the qualified rate of skin disinfection or incision infection rate between of patients the two groups(P>0.05).At 30 minutes after disinfection,60 minutes after disinfection,and at the end of surgery,the body temperature of patients in the observation group was significantly higher than that in the control group(P<0.05).The incidences of intraoperative hypothermia,delayed awakening,and shivering reaction of patients in the observation group were significantly lower than those in the control group(P<0.05).The intraoperative bleeding volume and postoperative drainage bleeding volume of patients in the observation group were significantly lower than those in the control group(P<0.05).The hemoglobin level 3 days after surgery of patients in the observation group was significantly higher than that in the control group(P<0.05).Conclusion Compared with the routine use of 23℃iodophor to disinfect the skin of elderly patients undergoing radical mastectomy,the use of iodophor heated to 37℃does not affect the disinfection effect and incision infection,and the incidence of intraoperative hypothermia in patients is lower,which is conducive to reduce the amount of intraoperative bleeding and the incidence of adverse reactions during the recovery period.

Objective To specify the occurrence status,distribution characteristics and risk factors of neglected perforations in surgical gloves used during spinal surgery.Methods A total of 932 surgical gloves used during spinal surgery in our hospital from October 2022 to September 2024 were selected.The occurrence and distribution location of neglected perforations were counted.Univariate and binary Logistic regression analyses were respectively conducted on the factors that might lead to neglected perforations of gloves.Results Among the 932 surgical gloves used in spinal surgery selected in this study,a total of 122 gloves(13.09％)with neglected perforations were detected,of which the proportions of neglected perforations at the index finger of the left and right hands in the gloves were the highest,accounting for 37.50％and 37.93％respectively.The results of univariate and binary Logistic regression analyses showed that grade Ⅲ or Ⅳ surgery,open surgery,combined bone grafting operation,operation time≥120 minutes,use of rotating equipment,and gloves worn by instrument nurses were risk factors for neglected perforations(P<0.05,OR>1.0),while wearing double-layer gloves was a protective factor to avoid the occurrence of neglected perforations(P<0.05,OR<1.0).Conclusion The incidence of neglected perforations in surgical gloves used during spinal surgery is relatively high,especially in the area of the glove index finger.For high-risk spinal surgeries(grade Ⅲ or Ⅳ surgery,open surgeries,combined bone grafting procedures)and requiring rotating equipment,health care workers,especially instrumental nurses,are advised to wear double-layer gloves;furthermore,a 120-minute glove change regime is recommended,in order to reduce the incidence of neglected perforation.

Background::B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T (CAR-T) therapy yield remarkable responses in patients with relapsed/refractory multiple myeloma (R/RMM). Circulating tumor DNA (ctDNA) reportedly exhibits distinct advantages in addressing the challenges posed by tumor heterogeneity in the distribution and genetic variations in R/RMM.Methods::Herein, the ctDNA of 108 peripheral blood plasma samples from patients with R/RMM at the First Affiliated Hospital, School of Medicine, Zhejiang University was thoroughly investigated before administration of anti-BCMA CAR-T therapy to establish its predictive potential. Flow cytometry is used primarily to detect subgroups of T cells or CAR-T cells.Results::In this study, several tumor and T cell effector-mediated factors were considered to be related to treatment failure by an integrat analysis, including higher percentages of multiple myeloma (MM) cells in the bone marrow ( P = 0.0125), lower percentages of CAR-T cells in the peripheral blood at peak ( P = 0.0375), and higher percentages of CD8 + T cells ( P = 0.0340). Furthermore, there is a substantial correlation between high ctDNA level (>143 ng/mL) and shorter progression-free survival (PFS) ( P = 0.007). Multivariate Cox regression analysis showed that high levels of ctDNA (>143 ng/mL), MM-driven high-risk mutations (including IGLL5 [ P = 0.004], IRF4 [ P = 0.024], and CREBBP [ P = 0.041]), number of multisite mutations, and resistance-related mutation ( ERBB4, P = 0.040) were independent risk factors for PFS. Conclusion::Finally, a ctDNA-based risk model was built based on the above independent risk factors, which serves as an adjunct non-invasive measure of substantial tumor burden and a prognostic genetic feature that can assist in predicting the response to anti-BCMA CAR-T therapy.

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 application value of fascial platform versus commercial platform in transumbilical single-port laparoscopic transabdominal preperitoneal repair(TAPP)for inguinal hernia.Methods One hundred patients with inguinal hernia admitted between January and December 2024 were prospectively enrolled and randomly assigned to either the fascial platform group(n=50)or the commercial platform group(n=50)by using a random number table.The following parameters were compared between the two groups:platform establishment time,operative time,intraoperative blood loss,incision suture time,operative difficulty score,camera manipulation difficulty score,postoperative 24-hour Visual Analogue Scale(VAS)score of pain,postoperative hospital stay,total hospitalization cost,comprehensive satisfaction score,and postoperative complications.Results The fascial platform group demonstrated significantly superior outcomes compared to the commercial platform group in platform establishment time[(3.4±1.0)min vs.(8.1±1.5)min,t=-18.389,P＜0.001],operative time[(67.5±7.9)min vs.(72.2±11.5)min,t=-2.380,P=0.019],intraoperative blood loss[(8.3±4.3)ml vs.(11.1±5.7)ml,t=-2.798,P=0.006],incision suture time[(7.0±1.4)min vs.(11.8±2.7)min,t=-11.212,P＜0.001],operative difficulty score(14.4±3.6 vs.23.1±4.1,t=-11.215,P＜0.001),camera manipulation difficulty score(11.4±2.6 vs.18.3±2.5,t=-13.370,P＜0.001),VAS score of postoperative 24-hour pain(2.4±1.0 vs.3.7±1.1,t=-6.139,P＜0.001),total hospitalization cost[(15.8±1.6)thousand yuan vs.(18.3±1.6)thousand yuan,t=-7.841,P＜0.001],and comprehensive satisfaction score(7.3±1.1 vs.6.3±1.0,t=5.271,P＜0.001).However,there were no statistically significant differences in postoperative hospital stay or postoperative complication between the two groups(P＞0.05).All the patients were followed up for 1-12 months postoperatively[(5.3±1.8)months vs.(5.7±2.0)months,t=-0.945,P=0.347],with no recurrence observed in either group.Conclusions Both fascial platform and commercial platform can be used for transumbilical single-port TAPP.The fascial platform offers advantages including shorter platform establishment time,reduced incision suture time,lower operative and camera manipulation difficulty,decreased cost,less postoperative pain,and higher patient satisfaction.

The chemical constituents were systematically separated from the roots of Berberis polyantha by various chromatographic methods, including silica gel column chromatography, HP20 column chromatography, polyamide column chromatography, reversed-phase C_(18) column chromatography, and preparative high-performance liquid chromatography. The structures of the compounds were identified by physicochemical properties and spectroscopic techniques(1D NMR, 2D NMR, UV, MS, and CD). Four phenylpropanoids were isolated from the methanol extract of the roots of B. polyantha, and they were identified as(2R)-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone-O-β-D-glucopyranoside(1), methyl 4-hydroxy-3,5-dimethoxybenzoate(2),(+)-syringaresinol(3), and syringaresinol-4-O-β-D-glucopyranoside(4). Compound 1 was a new compound, and other compounds were isolated from this plant for the first time. The anti-inflammatory activity of these compounds was evaluated based on the release of nitric oxide(NO) in the culture of lipopolysaccharide(LPS)-induced RAW264.7 macrophages. At a concentration of 10 μmol·L~(-1), all the four compounds inhibited the LPS-induced release of NO in RAW264.7 cells, demonstrating potential anti-inflammatory properties.

This study aims to investigate the effect of Chaijin Jieyu Anshen Formula on the neuroinflammation of rats with insomnia complicated with depression through the regulation of triggering receptor expressed on myeloid cells 2(TREM2)/complement protein C1q signaling pathway. Rats were randomly divided into a normal group, a model group, a positive drug group, as well as a high, medium, and low-dose groups of Chaijin Jieyu Anshen Formula, with 10 rats in each group. Except for the normal group, the other groups were injected with p-chlorophenylalanine and exposed to chronic unpredictable mild stress to establish the rat model of insomnia complicated with depression. The sucrose preference experiment, open field experiment, and water maze test were performed to evaluate the depression in rats. Enzyme-linked immunosorbent assay was employed to detect serum 5-hydroxytryptamine(5-HT), dopamine(DA), and norepinephrine(NE) levels. Hematoxylin and eosin staining and Nissl staining were used to observe the damage in nucleus accumbens neurons. Western blot and immunofluorescence were performed to detect TREM2, C1q, postsynaptic density 95(PSD-95), and synaptophysin 1(SYN1) expressions in rat nucleus accumbens, respectively. Golgi-Cox staining was utilized to observe the synaptic spine density of nucleus accumbens neurons. The results show that, compared with the model group, Chaijin Jieyu Anshen Formula can significantly increase the sucrose preference as well as the distance and number of voluntary activities, shorten the immobility time in forced swimming test and the successful incubation period of positioning navigation, and prolong the stay time of space exploration in the target quadrant test. The serum 5-HT, DA, and NE contents in the model group are significantly lower than those in the normal group, with the above contents significantly increased after the intervention of Chaijin Jieyu Anshen Formula. In addition, Chaijin Jieyu Anshen Formula can alleviate pathological damages such as swelling and loose arrangement of tissue cells in the nucleus accumbens, while increasing the Nissl body numbers. Chaijin Jieyu Anshen Formula can improve synaptic damage in the nucleus accumbens and increase the synaptic spine density. Compared to the normal group, the expression of C1q protein was significantly higher in the model group, while the expression of TREM2 protein was significantly lower. Compared to the model group, the intervention with Chaijin Jieyu Anshen Formula significantly downregulated the expression of C1q protein and significantly upregulated the expression of TREM2. Compared with the model group, the PSD-95 and SYN1 fluorescence intensity is significantly increased in the groups receiving different doses of Chaijin Jieyu Anshen Formula. In summary, Chaijin Jieyu Anshen Formula can reduce the C1q protein expression, relieve the TREM2 inhibition, and promote the synapse-related proteins PSD-95 and SNY1 expression. Chaijin Jieyu Anshen Formula improves synaptic injury of the nucleus accumbens neurons, thereby treating insomnia complicated with depression.
