Objective To investigate the effect of bone metabolic markers on sarcopenia in elderly patients with type 2 diabetes mellitus (T2DM). Methods A total of 412 patients with T2DM in the department of endocrinology of Nanjing Central Hospital from May 2020 to June 2025 were selected as the research subjects. According to Asian Working Group for Sarcopenia (AWGS) in 2019, these patients were evaluated for skeletal muscle mass index (ASMI), muscle strength, and muscle function, and were divided into a sarcopenia group (84 cases) and a non-sarcopenia group (328 cases). The glucolipid metabolic indexes were detected in both groups of patients, and the bone metabolic markers were evaluated, including procollagen type 1 N-terminal peptide (P1NP), beta-C-terminal telopeptide of type 1 collagen (β-CTX), and 25-hydroxy vitamin D [25-(OH)D]. The factors influencing the occurrence of sarcopenia in T2DM patients were analyzed by logistic regression analysis, and the diagnostic values of bone metabolic markers on sarcopenia in patients with T2DM were assessed by ROC curve. Results The levels of P1NP and 25-(OH)D were lower, while β-CTX level was higher in the sarcopenia group compared to the non-sarcopenia group, with statistical differences (P<0.05). After logistic correlation analysis, it was found that P1NP, β-CTX and 25-(OH)D were all influencing factors for the occurrence of sarcopenia in T2DM patients. ROC curve analysis suggested that combined detection of PINP, β-CTX, and 25-(OH)D had higher diagnostic value, with an area under the curve up to 0.805. Conclusion The abnormal expression of bone metabolic markers is associated with the increased risk of sarcopenia in patients with T2DM. The detection of serum bone metabolic markers expression level is of certain significance for the assessment of diabetes-related sarcopenia.

Objective: To investigate the association characteristics between psychological resilience and Internet gaming addiction among primary and secondary school students across different educational stages, so as to provide evidence for stage specific intervention strategies. Methods: A total of 30 719 students from primary schools, junior high schools, and senior high schools in Guangzhou, were selected using a cluster random sampling method from October to December 2025. The 10 item Connor- Davidson Resilience Scale (CD-RISC-10) and the Internet Gaming Disorder Scale-Short Form (IGDS9-SF) were used to assess students phychological resilience and Internet gaming addication levels. One way analysis of variance was used for group comparisons. Network analysis was conducted to construct joint networks of psychological resilience and Internet gaming addiction across different educational stages, with a focus on identifying bridge nodes between the two domains. Results: Significant differences were observed in psychological resilience points (24.9±8.0, 24.3±8.2, 24.8±7.8) across priamry school, junior high school and senior high school ( F=18.91, P <0.01). There was a statistically significant difference in the scores of Internet game addiction points ( 17.7 ±7.6, 18.6±7.3, 19.2±7.0) among students across priamry school, junior high school and senior high school ( F=85.68, P <0.01). Psychological resilience was negatively correlated with Internet gaming addiction scores among primary school, junior high school, and senior high school students ( r =-0.27, -0.28, -0.19, all P <0.01). Network analysis revealed relatively close associations between psychological resilience and Internet gaming addiction across all educational stages. The bridge nodes were "withdrawal symptoms" for primary school, "toughness" for junior high school, and "loss of interest" for senior high school, with bridge expected influence values of 1.37, 1.31, and 1.18, respectively. The expected influence and bridge expected influence demonstrated good stability across the three educational stages, with correlation stability coefficients of 0.75. Conclusions The cross-community connections between psychological resilience and Internet gaming addiction differ across educational stages. Prevention and control of Internet gaming addiction should incorporate targeted interventions based on key bridge symptoms identified at each specific educational stage.

Objective To explore the effects and potential mechanism of electroacupuncture at acute phase on cognitive dysfunction at later stage in rats with middle cerebral artery occlusion(MCAO).Methods Totally 39 SD rats were randomly divided into sham-operation group,model group and electroacupuncture group,with 13 rats in each group.MCAO model was established by Zea Longa thread embolism method in model group and electroacupuncture group.The sham-operation group only separated blood vessels.Electroacupuncture group was treated with electroacupuncture at"Baihui"and"Shenting"acupoints at 5 min and 6 h after model establishment respectively,for 30 min.The body mass,modified neuropathy severity scale(mNSS),and percentage of stiff immobility time of rats were monitored weekly,Nissl staining was used to observe the morphology of hippocampal tissue on the 28 d,immunofluorescence staining was used to detect the expression of Ki67,dual cortin(DCX)and neuronal differentiation factor 1(NeuroD1)in dentate gyrus of the hippocampus,the expression of synaptic vesicle protein 2A(SV2A)protein in dentate gyrus of hippocampus was detected by Western blot.Results Compared with the sham-operation group,on the first day after operation,the body mass of the model group rats decreased,then gradually increased,and on the 28th day,the body mass was still lower than that of the sham-operation group(P<0.05);on the first day after operation,the mNSS score significantly increased,gradually decreased thereafter,and remained higher than the sham-operation group until the 28th day(P<0.01);the percentage of stiff immobility time significantly decreased on the first day after operation,gradually stabilized,and remained lower than the sham-operation group on the 28th day(P<0.05);the hippocampal tissue structure was significantly damaged,and the density of Ki67+DCX+NeuroD1 positive cells in the dentate gyrus of hippocampus was significantly increased(P<0.05),the expression of SV2A protein in the dentate gyrus of hippocampal was significantly decreased(P<0.05).Compared with the model group,the body mass of rats in the electroacupuncture group showed an increasing trend(P<0.05),the mNSS score decreased(P<0.01),and the percentage of stiff immobility time increased(P<0.05);the ischemic injury area was significantly reduced,the structure was clearer,and the disordered and irregularly cells arrangement were reduced,the density of Ki67+DCX+NeuroD1 positive cells in the dentate gyrus of hippocampus significantly increased(P<0.05),and the expression of SV2A protein in the dentate gyrus of hippocampal significantly increased(P<0.05).Conclusion Electroacupuncture at acute phase at"Baihui"and"Shenting"can promote the recovery of cognitive dysfunction in MCAO rats in the later stage,and its mechanism may be related to enhancing the proliferation and differentiation of neural precursor cells in the dentate gyrus of hippocampus,promoting neurogenesis.

Objective:To assess the effects of recognition function of four-lead electrocardiogram(ECG)synchronization technique and multi-parameter fusion technique in reducing the number of false alarms and improving the quality of alarms in intensive care units(ICU).Methods:Four-lead ECG synchronization technique and multi-parameter fusion technique were used to strengthen the monitoring and assessment for the alarm of clinical monitors,and reduce the false alarm rate of monitors.The clinical alarm data of bed units corresponding to 48 monitors in clinical use of ICU,cardiovascular intensive care unit(CCU)and neurosurgery intensive care unit(NICU)of Hainan General Hospital from October 14 to December 27,2024 were selected.According to the opening and close of the four-lead ECG synchronization and multi-parameter fusion technique algorithm of the monitors,they were divided into group A(opened four-lead ECG synchronization and multi-parameter fusion),group B(opened four-lead ECG synchronization,but closed multi-parameter fusion),group C(closed four-lead ECG synchronization,but opened multi-parameter fusion)and group D(closed four-lead ECG synchronization and multi-parameter fusion),with 12 units in each group.The numbers of total alarms and false alarms generated by monitor of each bed unit among different optimization strategies were compared.Results:The numbers of average daily alarm of the monitors in groups A,B and C were respectively(134.2±32.4)cases,(392.5±68.2)cases and(583.4±126.5)cases,which were lower than those in group D(1 073.2±168.6),with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).The optimization rates of the alarm numbers in groups A,B and C were increased by 87.51%,63.47%and 45.67%,respectively.The rates of average false alarm of the monitors in groups A,B and C were respectively(1.04±0.15)%,(1.73±0.12)%and(2.07±0.08)%,which were lower than(3.76±0.2)%in group D,with statistically significant differences(Z=3.45,2.94,2.52,P<0.05).Conclusion:Four-lead ECG synchronization technique and multi-parameter fusion technique can effectively optimize the number of alarms in ICU,and reduce the proportion of false alarms of monitors in department,and decrease fatigue of medical staffs for alarm.

The core pathogenesis of disease caused by latent toxin is deficiency of healthy qi and lingering pathogen, which is characterized by lingering and recurrent courses, and onset upon exogenous induction. The biological mechanisms of disease caused by latent toxin present multi-dimensional and synergistic characteristics. Immune dysfunction and inflammatory response serve as the core links, involving the abnormal activation of signaling pathways such as Wnt/β-catenin, PI3K/Akt/mTOR, TLR, and NF-κB; the accumulation of metabolites, as the microscopic carrier of latent toxin, participates in chronic complications of diabetes by damaging vascular endothelium and inhibiting repair pathways; immune escape and tolerance, as well as weakened tumor suppressor function, supplement the potential mechanisms of latent toxin from the perspectives of pathogen/tumor cell latency and congenital insufficiency; the imbalance of tissue repair and remodeling, and the imbalance of protein metabolism and cellular homeostasis further improve the mechanism network of latent toxin. Among these, immune dysfunction, tumor suppressor gene mutation, and regulatory dysfunction may be the microscopic manifestations of "healthy qi deficiency"; inflammatory factors, metabolites, viruses, and tumor cells may be the microscopic manifestations of "latent toxin". Current studies have limitations, such as unclear specific biomarkers for different types of latent toxin, insufficient research on the interaction of multiple mechanisms, and lack of clinical verification. It is suggested that future research should be further carried out around "latent toxin classification-mechanism-efficacy".

Objective To investigate the effect of moxibustion on different phenotypic expression of macrophages in rheumatoid arthritis(RA).Methods Thirty rats were randomly divided into the blank group,the model group and the moxibustion group,with 10 rats in each group.Rats in the model group and the moxibustion group were injected with complete Freund's adjuvant(CFA)into right foot pad to prepare RA model.The moxibustion group received moxibustion treatment.The blank group was injected with the same amount of normal saline.The thickness of foot pad was measure and arthritis index score was performed.Pathological changes of joints were observed by hematoxylin eosin staining(HE),and the expressions of CD80,CD163 and SPP1 in macrophages of synovial tissue were detected by immunofluorescence.Results Compared with the blank group,arthritis index score and thickness of foot pad were increased in the model group and the moxibustion group(P＜0.05).After moxibustion treatment,compared with the model group,the score of arthritis index and thickness of foot pad were decreased in the moxibustion group(P＜0.05).HE staining showed joint space narrowing,subchondral bone destruction and inflammatory cell infiltration in the model group.The degree of joint space narrowing,subchondral bone destruction and inflammatory cell infiltration were less in the moxibustion group than those in the model group.Compared with the blank group,the scores of synovial tissue hyperplasia,synovial fibrous tissue hyperplasia and inflammatory cell infiltration increased in the model group.Compared with the model group,scores of synovial tissue hyperplasia,fibrous tissue hyperplasia and inflammatory cell infiltration decreased in the moxibustion group(P＜0.05).Results of immunofluorescence detection showed that compared with the blank group,the expressions of CD80 and SPP1 in synovial tissue were up-regulated in the model group,while the expression of CD163 was down-regulated.Compared with the model group,the expressions of CD80 and SPP1 were down-regulated,and the expression of CD163 was up-regulated in the moxibustion group(P＜0.05).Conclusion Moxibustion can regulate the expression of different phenotypes of macrophages and reduce synovial inflammation of RA.The mechanism may be related to regulating the expression of different phenotypes of macrophages.

Objective To explore the clinical application value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI T1 mapping in the evaluation of liver function.Methods Sixty-four patients who underwent enhanced MRI T1 mapping with Gd-EOB-DTPA and completed the laboratory examination of liver function within one week were prospectively enrolled.All patients were divided into normal control group(NCG),cirrhosis Child-Pugh A(CCA)group,cirrhosis Child-Pugh B(CCB)group,and cirrhosis Child-Pugh C(CCC)group.CCB+CCC groups were defined as a moderate and severe abnormal liver function group.The T1 mapping images of pre-enhanced,post-enhanced 10 min and 20 min were collected,and the T1 mapping val-ues of liver and spleen were measured.The ΔT1 and hepatocyte enhancement fraction(HEF)were calculated.The differences of parameters in different liver function groups were analyzed and compared,and the diagnostic efficacy of each index in distinguishing different liver function groups was evaluated.Results There were significant differences in T1plain scan,T110 min,T120 min,ΔT110 min,ΔT120 min,HEF10 min and HEF20 min among the three groups(P<0.05).The difference of T1plain scan between NCG and CCA groups,and between NCG and CCB+CCC groups was statistically significant(P<0.05).The area under the curve(AUC)of differentiating normal liver function group from abnormal liver function group was 0.761.There were significant differences in T110 min,T120 min,ΔT110 min,ΔT120 min,HEF10 min and HEF20 min between CCA and CCB+CCC groups.The AUC of differentiating the two groups was 0.757,0.820,0.735,0.820,0.790 and 0.853,respectively,and HEF20 min had the highest diagnostic efficacy.Conclusion Gd-EOB-DTPA enhanced MRI T1 mapping can be used as an effective method to evaluate liver function.

Non-alcoholic fatty liver disease(NAFLD)is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes.If not intervened in time,NAFLD may develop into liver fibrosis or liver cancer,and ultimately threatening life.NAFLD has complicated etiology and pathogenesis,and there are no effective therapeutic means and specific drugs.Currently,insulin sensitizers,lipid-lowering agents and hep-atoprotective agents are often used for clinical intervention,but these drugs have obvious side effects,and their effectiveness and safety need to be further confirmed.Adenosine monophosphate(AMP)-activated protein kinase(AMPK)plays a central role in maintaining energy homeostasis.Activated AMPK can enhance lipid degradation,alleviate insulin resistance(IR),suppress oxidative stress and inflammatory response,and regulate autophagy,thereby alleviating NAFLD.Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects.In this article,we reviewed the biologically active natural herbal medicines(such as natural herbal medicine formulas,extracts,polysaccharides,and monomers)that reported in recent years to treat NAFLD via regulating AMPK,which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes. If not intervened in time, NAFLD may develop into liver fibrosis or liver cancer, and ultimately threatening life. NAFLD has complicated etiology and pathogenesis, and there are no effective therapeutic means and specific drugs. Currently, insulin sensitizers, lipid-lowering agents and hepatoprotective agents are often used for clinical intervention, but these drugs have obvious side effects, and their effectiveness and safety need to be further confirmed. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays a central role in maintaining energy homeostasis. Activated AMPK can enhance lipid degradation, alleviate insulin resistance (IR), suppress oxidative stress and inflammatory response, and regulate autophagy, thereby alleviating NAFLD. Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects. In this article, we reviewed the biologically active natural herbal medicines (such as natural herbal medicine formulas, extracts, polysaccharides, and monomers) that reported in recent years to treat NAFLD via regulating AMPK, which can serve as a foundation for subsequent development of candidate drugs for NAFLD.
