OBJECTIVE To analyze the impact of the diagnosis-related groups (DRG) payment reform on the length of stay and medical costs in patients with chronic obstructive pulmonary disease (COPD) in Kashgar region, aiming to provide localized empirical evidence for the optimization of regional medical insurance payment methods. METHODS Based on the inpatient settlement database of the Xinjiang Uygur Autonomous Region Healthcare Security Administration, settlement data of COPD inpatients from 17 medical institutions in Kashgar region between January 1, 2022, and December 31, 2024, were extracted. The overall changes in patients’ length of stay and costs were compared before and after the reform. Subsequently, interrupted time series analysis (ITSA) was employed to explore the impact of the DRG payment reform on these variables. RESULTS Following the reform, both the average length of stay and various cost decreased significantly compared to the pre-reform period ( P <0.001). At the overall sample level, the average length of stay, average total cost, average drug cost, average medical service cost, and average examination cost per admission all demonstrated significant long-term downward trends after the reform ( P <0.05). However, the decrease in average out-of-pocket costs and the increase in average consumable costs per admission were not statistically significant ( P >0.05). In tertiary medical institutions, the average length of stay and all categories of costs (except average consumable costs per admission) exhibited significant long-term upward trends after the reform ( P <0.05); conversely, in secondary and lower-level medical institutions, the average length of stay, average total cost, average drug cost, average medical service cost, and average examination cost per admission showed significant long-term downward trends ( P <0.05). CONCLUSIONS The DRG payment reform has achieved an overall effect of reducing the length of stay and controlling costs in COPD patients from Kashgar region. However, the effects vary across different levels of medical institutions: secondary and lower-level institutions show a long-term downward trend in length of stay and costs, whereas tertiary institutions exhibit a long-term upward trend. Furthermore, patients’ out-of-pocket financial burden does not show significant improvement.

Background Work-related musculoskeletal disorders (WMSDs), as one of the major occupational health issues worldwide, have shown an increasing positive rate year by year. Due to the unique demands of work, operating room nurses exhibit a higher positive rate of WMSDs compared to other occupational groups, necessitating active attention and intervention. Objective To estimate the prevalence of WMSDs among operating room nurses in tertiary hospitals, explore the characteristics and latent categories of WMSDs, and analyze the influencing factors associated with the occurrence of WMSDs. Method Using a randomized cluster sampling method, operating room nurses from nine tertiary hospitals in Urumqi were selected as study participants between December 2023 and January 2024. Data were collected through a general information questionnaire, an ergonomic questionnaire for operating room nurses, and the Chinese Musculoskeletal Disorders Questionnaire. Latent class analysis was employed to examine the patterns of WMSDs among the nurses, while chi-square test and multinomial logistic regression were utilized to analyze the influencing factors of WMSDs. Result A total of 411 valid questionnaires were collected in this survey. The positive rate of WMSDs among operating room nurses in the tertiary hospitals of Urumqi over the past year was 91.9%. The positive rates, ordered from highest to lowest by body region, were neck (79.1%), shoulders (70.3%), and lower back (68.1%). The operating room nurses were categorized into three distinct groups by latent class analysis: multi-site pain group, neck-shoulder-back pain group, and neck and lower back pain group. The results of the multinomial logistic regression models revealed that gender, job strain level, ergonomic load level in the operating room, and exposure to cold or drafty working conditions or not were significant influencing factors for reporting WMSDs among operating room nurses. Specifically, having less than 5 years of work experience, low ergonomic load level, low job strain, and moderate job strain were identified as protective factors against WMSDs. Conversely, exposure to cold or drafty working environments and being female were identified as risk factors for WMSDs. The logistic regression models also indicated that compared to the neck-lower back pain group, the neck-shoulder-back pain group had a higher probability of reporting low job strain (OR=0.168, 95%CI: 0.029, 0.968) and being female (OR=4.847, 95%CI: 2.506, 9.378). In contrast, when comparing to the neck-lower back pain group, the multi-site pain group had a higher probability of reporting, low-level ergonomic workload (OR=0.079, 95%CI: 0.015, 0.412), low job strain (OR=0.019, 95%CI: 0.002, 0.145), moderate job strain (OR=0.080, 95%CI: 0.016, 0.401), high job strain (OR=0.132, 95%CI: 0.027, 0.647), less than 5 years of work experience (OR=0.173, 95%CI: 0.044, 0.683), being female (OR=2.424, 95%CI: 1.130, 5.200), and exposure to cold or drafty working environments (OR=3.277, 95%CI: 1.657, 6.481). Conclusion The positive rate WMSDs among operating room nurses in tertiary hospitals is notably high in Urumqi, with distinct co-occurrence characteristics observed within the population. To mitigate the risk of WMSDs, it is essential to implement targeted health education and prevention training programs tailored to different patterns of WMSDs. Additionally, improving working conditions, optimizing human resource allocation , and other proactive measures should be undertaken. These efforts will effectively reduce the incidence of WMSDs among operating room nurses and safeguard their occupational health.

Protein arginine methyltransferase 5 (PRMT5) acts as an oncogene in liver cancer, yet its roles and in-depth molecular mechanisms within the liver cancer immune microenvironment remain mostly undefined. Here, we demonstrated that disruption of tumor-intrinsic PRMT5 enhances CD8+ T-cell-mediated antitumor immunity both in vivo and in vitro. Further experiments verified that this effect is achieved through downregulation of the inhibitory immune checkpoint molecule, fibrinogen-like protein 1 (FGL1). Mechanistically, PRMT5 catalyzed symmetric dimethylation of transcription factor 12 (TCF12) at arginine 554 (R554), prompting the binding of TCF12 to FGL1 promoter region, which transcriptionally activated FGL1 in tumor cells. Methylation deficiency at TCF12-R554 residue downregulated FGL1 expression, which promoted CD8+ T-cell-mediated antitumor immunity. Notably, combining the PRMT5 methyltransferase inhibitor GSK591 with PD-L1 blockade efficiently inhibited liver cancer growth and improved overall survival in mice. Collectively, our findings reveal the immunosuppressive role and mechanism of PRMT5 in liver cancer and highlight that targeting PRMT5 could boost checkpoint immunotherapy efficacy.

To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen, kidney essence deficiency, liver constraint transforming into fire, and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen (TE 21), Tinggong (SI 19), Tinghui (GB 2), Shenmai (BL 62) to regulate qi and blood, and supporting with Baihui (GV 20), Yintang (EX-HN 3), Taichong (LR 3), and Yanglingquan (GB 34) to soothe the liver, resolve constraint, and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction (益气聪明汤) and Tongqi Powder (通气散), and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder (温清散) to navel moxibustion.

Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease, making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine (TCM) in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation, using standardized measurements of the overall TCM condition, multi-omics research of hematologic tumors, and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma, thereby establishing a risk warning system for virus-related lymphoma. At the same time, a TCM health management approach will be applied to manage and regulate virus-related lymphoma, interrupting its progression and forming a human-centered, comprehensive, continuous health service model. Based on this, a standardized, integrated clinical prevention and treatment decision-making model for virus-related lymphoma, recognized by both Chinese and western medicine, will be established to provide TCM solutions for primary prevention of major malignant tumors.

Objective:
To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators.
Methods:
From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed.
Results:
Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05).
Conclusion
The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

Objective:To explore how benzydamine (BA) improves brain edema in mice after cerebral ischemia-reperfusion.Methods:(1) One hundred and twenty 8 week-old male C57BL/6 mice were randomly divided into a sham-operated group, a middle cerebral artery occlusion (MCAO) group, a MCAO+low-dose BA group (L-BA group), and a MCAO+high-dose BA group (H-BA group), with 30 mice in each group. MCAO models in mice of the later 3 groups were established by suture method, while mice in the sham-operated group underwent the same surgical procedure without MCAO. At 6 hours after modeling, mice in the L-BA group and H-BA group were intraperitoneally injected with 5 mg/kg or 10 mg/kg BA, respectively, once daily for 3 days, while mice in the shamoperated group and MCAO group were intraperitoneally injected with same volume of normal saline instead. Dynamics of cerebral perfusion were monitored by laser speckle imaging in MCAO model mice at baseline, during occlusion, and following reperfusion. Three days after modeling, neurological deficits were assessed by modified neurological severity score (mNSS), neurological function was evaluated by forelimb grip strength and rotarod tests; cerebral infarct size was detected by 2,3,5-triphenyltetrazolium chloride (TTC) staining, and neuronal death was assessed by Fluoro-Jade B staining; cerebral edema was quantified by dry-wet weight method, blood-brain barrier (BBB) permeability was assessed by Evans blue dye extravasation, and expressions of tight junction proteins (Claudin-5, zonula occludens-1 [ZO-1]) were detected by immunofluorescent staining; expressions of neutrophil extracellular traps (NETs)-related proteins (citrullinated histone H3 [citH3], myeloperoxidase [MPO] and matrix metalloproteinase 9 [MMP-9]) were determined by Western blotting. (2) Bone marrow neutrophils were extracted from male C57BL/6 mice and randomly divided into a control group, a phorbol 12-myristate 13-acetate (PMA) group, and a PMA+BA group; neutrophils in the PMA group were stimulated with PMA (50 nmol/L), while neutrophils in the PMA+BA group were co-treated with 50 nmol/L PMA and 50 μmol/L BA; and those in the control group were given an equal amount of dimethyl sulfoxide. Sytox Green staining was used to detect the NETs proportion in neutrophils.Results:(1) Baseline cerebral perfusion was robust (1 237.75±98.16 PU), which was markedly reduced during occlusion (297.36±77.63 PU) in the ipsilateral middle cerebral artery territory, and improved following reperfusion (939.21±73.63 PU). Compared with the MCAO group, mice in the L-BA group and H-BA group had lower mNSS score, increased paw grip strength, prolonged rotarod retention time, reduced infarct size, fewer neuronal death, lower brain tissue water content, reduced blood-brain barrier permeability, increased fluorescent intensities of Claudin-5 (0.51±0.11, 0.71±0.04, and 0.83±0.05) and ZO-1 (0.43±0.09, 0.65±0.05, and 0.81±0.03), and decreased protein expressions of citH3 (2.33±0.15, 1.92±0.03, and 1.42±0.04), MPO (2.14±0.08, 1.71±0.06, and 1.37±0.03) and MMP-9 (2.62±0.09, 1.83±0.06, and 1.41±0.05), with significant differences ( P<0.05). All the above changes in the H-BA group were more significant than those in the L-BA group ( P<0.05). (2) Compared with that in the control group (10.00%±8.00%), the proportion of NETs formation per field in both PMA group (85.33%±2.08%) and PMA+BA group (58.46%±5.29%) was significantly increased ( P<0.05); the PMA+BA group showed a significant reduction in NETs formation compared with the PMA group ( P<0.05). Conclusion:BA can alleviate cerebral edema in mice after cerebral ischemia-reperfusion, and its mechanism may be involved in inhibiting NETs formation.

Objective:To investigate the effect of nefazodone on excessive activation of microglia and its regulatory mechanism, as well as its effect on neurological injury in mice subjected to middle cerebral artery occlusion (MCAO).Methods:(1) BV2 cell line was routinely cultured in vitro, and primary microglia from the cortex of neonatal C57BL/6J mice were cultured. Cell counting kit-8 (CCK-8) assay was employed to assess the effects of nefazodone (0, 10, 20, 30, 50 μmol/L) on viability of BV2 cells and primary microglia to determine the working concentration. BV2 cells and primary microglia were divided into a normal control group, a lipopolysaccharide (LPS) group, and a nefazodone group; cells in the nefazodone group were pretreated with 20 μmol/L nefazodone for 2 h; cells in the LPS group and nefazodone group were stimulated with LPS (0.5 μg/mL for BV2 cells and 0.1 μg/mL for primary microglia) for 24 h; cells in the normal control group received an equivalent volume of solvent. Immunofluorescent staining was used to detect the expressions of ionized calcium-binding adapter molecule 1 (Iba1) and CD68. Reverse transcription quantitative PCR (RT-qPCR) was performed to measure interleukin ( IL) -1β, IL-6, tumor necrosis factor-α ( TNF-α), nitric oxide synthase 2 ( Nos2), C-C motif chemokine ligand 2 ( CCL2), and β-hexosaminidase subunit β ( Hexb) mRNA expressions. ELISA was used to quantify the concentrations of supernatant IL-1β, IL-6, and TNF-α in BV2 cells. Western blotting was applied to detect the protein expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in BV2 cells. Griess reagent assay was used to measure supernatant nitric oxide (NO) level in BV2 cells. Western blotting was also used to assess the protein expressions of extracellular signal-regulated kinase (ERK), phosphorylated (p)-ERK, c-Jun N-terminal kinase (JNK), p-JNK, p38, p-p38, nuclear factor kappa B p65 and p-p65 in BV2 cells. (2) Thirty male C57BL/6J mice were randomly divided into a normal control group, a MCAO group, and a nefazodone group, with 10 mice in each group. MCAO model in the MCAO group and nefazodone group was established using suture method; the nefazodone group received an intraperitoneal injection of nefazodone (15 mg/kg) 30 min after modeling, while the normal control group received an equivalent volume of solvent. Three days after modeling, neurological deficits were evaluated using modified neurological severity score (mNSS), and behavioral changes were evaluated by paw grip strength test and foot-fault test. Cerebral infarction volume was assessed by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Iba1 protein expression in the ischemic penumbra was detected by Western blotting. Results:(1) CCK-8 assay showed no significant difference in viability of BV2 cells between the normal control group and 10 or 20 μmol/L nefazodone groups ( P>0.05), and viability of BV2 cells in 30 and 50 μmol/L nefazodone groups was statistically lower than that of normal control group ( P<0.05). Immunofluorescent staining revealed that compared with the normal control group, the LPS group had significantly increased fluorescent intensities of CD68 and Iba1; compared with the LPS group, the nefazodone group had significantly decreased fluorescent intensities of CD68 and Iba1 ( P<0.05). RT-qPCR results indicated that compared with those in the normal control group, the Nos2, CCL2, IL-1β, IL-6, and TNF-α mRNA expressions in both BV2 cells and primary microglia of the LPS group were significantly increased; compared with the LPS group, the nefazodone group had significantly decreased CCL2, IL-1β, and IL-6 mRNA expressions in BV2 cells, and significantly decreased Nos2, CCL2, IL-1β, IL-6, and TNF-α mRNA expressions in primary microglia ( P<0.05). ELISA showed that compared with those in the normal control group, the supernatant IL-1β, IL-6, and TNF-α levels significantly increased in the BV2 cells of LPS group; compared with those in the LPS group, supernatant IL-1β, IL-6 and TNF-α levels statistically decreased in the nefazodone group ( P< 0.05). Western blotting demonstrated that compared with those in the normal control group, the iNOS and COX-2 protein expressions significantly increased in BV2 cells of the LPS group ( P<0.05); compared with those in the LPS group, the iNOS and COX-2 protein expressions in BV2 cells of the nefazodone group statistically decreased ( P<0.05). Griess assay showed that compared with the normal control group, BV2 cells in the LPS group had significantly increased supernatant NO concentration ( P <0.05); compared with the LPS group, BV2 cells in the nefazodone group had significantly decreased supernatant NO concentration ( P<0.05). Western blotting revealed that compared with those in the normal control group, the p-ERK/ERK and p-JNK/JNK ratios significantly increased in BV2 cells of the LPS group ( P<0.05); compared with the LPS group, the p-p65/p65, p-ERK/ERK and p-JNK/JNK ratios significantly decreased in BV2 cells of the nefazodone group ( P<0.05). (2) Behavioral tests showed that compared with the normal control group, the MCAO group had significantly decreased forelimb grip strength and increased foot-fault rate ( P<0.05); compared with the MCAO group, the nefazodone group had significantly decreased mNSS score, increased forelimb grip strength and decreased foot-fault rate ( P<0.05). The percentage of cerebral infarction volume in the nefazodone group was significantly lower than that in the MCAO group ([9.56±1.81]% vs. [21.71±12.26]%, P< 0.05). The MCAO group had statistically higher Iba1 protein expression in ischemic penumbra (7.27±2.88) than the normal control group (1.00±0.64), and the nefazodone group had significantly lower Iba1 protein expression in ischemic penumbra (1.75±0.86) than the MCAO group ( P<0.05). Conclusion:Nefazodone can improve neurological function impairment in MCAO mice by inhibiting the excessive activation of microglia; cytological experiments suggest that its mechanism may be related to the negative regulation of ERK/JNK/NF-κB p65 signaling axis.
10.The role of adipocyte-specific calsyntenin 3β in obesity: From molecular mechanisms to clinical associations
Chinese Journal of Endocrinology and Metabolism 2025;41(8):704-707
Obesity is characterized by excessive accumulation of adipose tissue or ectopic lipid deposition, and is closely linked to insulin resistance and related metabolic disorders. Calsyntenin 3β(CLSTN3β) is a recently discovered protein that is specifically expressed in adipocytes. This article summarizes its role in obesity, from molecular mechanisms to clinical associations. Mechanistic studies have shown that mouse CLSTN3β, as an endoplasmic reticulum membrane protein, promotes lipid droplet multilocularity and lipid utilization in thermogenic adipocytes, while also facilitating lipid droplet maturation and lipid storage in white adipocytes. Clinical studies have revealed that the transcriptional profile of the human CLSTN3B gene in white adipose tissue tightly associated with obesity, and key metabolic traits, and that its genetic variation may play an important role. These findings will provide new insights and directions for intervention strategies aimed at improving obesity-associated metabolic disorders.
