Objective To analyze the relationship of protein intake level with high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in patients with diabetic kidney disease (DKD) and its influence on prognosis. Methods A total of 325 patients with DKD admitted from June 2021 to June 2024 were included and classified into a low protein group and a high protein group. The levels of hs-CRP, IL-6, and TNF-α were compared between the two groups of patients before follow-up and after 1 year of follow-up. The correlation was analyzed by linear mixed model. The incidence of endpoint events during follow-up and disease progression-free survival time were compared between the two groups. Results The inflammatory indicators exhibited no statistical differences between the two groups before follow-up (P>0.05). After 1 year of follow-up, the levels of hs-CRP, IL-6, and TNF-α in the two groups were higher than those before follow-up, and the levels in the high protein group were higher than those in the low protein group (P<0.05). Linear mixed model analysis suggested that the protein intake level, time, and the interaction term of protein intake level × time were correlated with the changes of hs-CRP, IL-6 and TNF-α levels (P<0.05). The incidence rate of endpoint events in the high-protein group during follow-up was 24.84% (40/161), which was significantly higher than 12.80% (21/164) in the low-protein group (χ²=7.724, P=0.005). The disease progression-free survival time was longer in the low-protein group than that in the high-protein group (Log Rank χ²=9.007, P=0.003). Conclusion The level of protein intake in patients with diabetic kidney disease is closely related to inflammatory response and prognosis.

Objective To explore the correlation between thyroid hormones and massive proteinuria in patients with type 2 diabetes mellitus (T2DM). Methods A total of 308 patients with T2DM admitted to 3201 Hospital between June 2020 and June 2025 were selected as the observation group, and another 250 healthy individuals who underwent physical examinations during the same period served as the control group. The thyroid hormones levels [free triiodothyronine (FT₃), thyroid stimulating hormone (TSH), and free thyroxine (FT₄)] were measured and compared between the two groups. Based on whether 24-hour urinary protein quantification was ≥ 3.5 g, the patients in the observation group were divided into a massive proteinuria group and a non-massive proteinuria group. Multivariate logistic regression analysis was used to analyze the factors influencing the occurrence of massive proteinuria in T2DM patients. Pearson method was applied to analyze the relationship of thyroid hormone indicators with severity indicators of massive proteinuria. Results Compared with the control group and the non-massive proteinuria group, FT₃ and FT₄ in the massive proteinuria group were lower, while TSH was higher (P<0.05). Multivariate logistic regression analysis suggested that glycosylated hemoglobin (OR=1.113, 95%CI: 1.045-1.185), TSH (OR=1.123, 95%CI: 1.006-1.253), eGFR (OR=0.894, 95%CI: 0.822-0.973), and FT₃ (OR=0.898, 95%CI: 0.828-0.973) were related factors for the occurrence of massive proteinuria in T2DM patients (P<0.05). Pearson correlation analysis revealed that FT3 and FT4 levels in T2DM patients were significantly negatively correlated with 24-hour urinary protein quantification (r=-0.514, -0.502), while the level of TSH was positively correlated with 24-hour urinary protein quantification (r=0.486) (P<0.001). Conclusion In T2DM patients, low FT3 and eGFR levels and high TSH and glycosylated hemoglobin levels are related factors for the occurrence of massive proteinuria, and thyroid hormone levels are significantly associated with the severity of massive proteinuria.

OBJECTIVE To provide guidance for pharmaceutical care in patients with severe Cryptococcus gattii infections.METHODS Clinical pharmacists participated in the diagnosis and treatment of a male patient with disseminated Cryptococcus gattii infection （involving the lungs and central nervous system）. Given the patient’s poor response to initial therapy， the clinical pharmacists， based on antimicrobial susceptibility test results， recommended voriconazole as an alternative azole. In response to refractory hypokalemia caused by liposomal amphotericin B， the clinical pharmacists assisted the physician in developing an intensive potassium replacement regimen. Regarding the interaction between voriconazole and nifedipine， the clinical pharmacists proactively identified the risk and intensified monitoring of the patient’s blood pressure. In response to the onset of hepatitis C during treatment， the clinical pharmacists thoroughly weighed the priority of infection treatment and recommended temporarily postponing antiviral therapy for hepatitis C. For the individualized use of voriconazole， the clinical pharmacists repeatedly performed therapeutic drug monitoring （TDM）. Regarding the patient’s poor lesion resolution， the clinical pharmacists participated in multidisciplinary team discussions to clarify the indications for surgery.RESULTS The physician adopted the clinical pharmacists’ recommendations. Following pharmacological treatment and surgical intervention， the patient’s condition stabilized， and he was discharged while still on medication.CONCLUSIONS For severe Cryptococcus gattii infections， clinical pharmacists should focus on pathogen characteristics， strengthen adverse reaction management， pay close attention to drug interactions， conduct TDM， and actively participate in multidisciplinary team collaboration to ensure the safety and efficacy of patient treatment.

Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

Objective:To explore the latent-classes of HIV high risk behaviors among college students, and the association between experiences of intimate partner violence (IPV) and HIV high risk behaviors, to provide evidence for reducing the HIV high risk behaviors among them.Methods:A cross-sectional study was conducted from October to December 2019 among university students from six higher education institutions in Zhuhai City, using a multi-stage cluster sampling method, with an estimated sample size of 1 318. The study included participants who self-reported being in a romantic relationship and having sexual experience within the past year. Data on sociodemographic characteristics, IPV experiences, and HIV high risk behaviors were collected. Latent-class analysis was performed on HIV high risk behaviors, and chi-squared tests and multivariable logistic regression were used to analyze the associations between IPV experiences and different latent classes of HIV high risk behaviors.Results:The effective response rate for the survey was 95.4% (12 235/12 821). 1 382 college students from Zhuhai were included as participants in the study, with 19.4% (268/1 382) self-reporting having experienced IPV. Latent-class analysis of HIV high risk behaviors classified the participants into three latent groups: low-risk group (78.1%, 1 079/1 382), multiple sexual partners/alcohol use before sex group (15.8%, 219/1 382), and high-risk group (6.1%, 84/1 382). Multivariable logistic regression analysis showed that students who had experienced psychological violence were more likely to be in the group that had multiple sexual partners/alcohol use before sex (a OR=2.51, 95% CI:1.48-4.27). Those who had experienced IPV (a OR=5.74, 95% CI:3.45-9.55), physical violence (a OR=9.26, 95% CI: 5.24-16.35), sexual violence (a OR=8.46, 95% CI:4.93-14.52), or psychological violence (a OR=15.99, 95% CI:8.64-29.57) were more likely to be in the high-risk group. Students who experienced two (a OR=9.37, 95% CI:3.55-24.71) or three types of IPV (a OR=50.09, 95% CI: 21.06-119.14) were more likely to be in the high-risk group compared to those with no IPV experiences. Conclusions:HIV high risk behaviors among college students in Zhuhai exhibited heterogeneity across different latent groups, and these groups have different associations with IPV experiences. Universities should tailor targeted HIV/AIDS education and prevention strategies based on the characteristics of each latent group to reduce HIV high risk behaviors among college students.

Objective:To explore the risk fall death associated with compound hot extremes.Methods:This study collected data on fall deaths in Guangdong, Hunan, and Zhejiang Provinces from 2013 to 2018 and matched their exposure to meteorological data. Based on a time-stratified case-crossover design, a conditional logistic regression model embedded with a cross-basis function of the distributed lag nonlinear model was applied to estimate the risk of fall to death due to compound hot extremes.Results:Compared with regular days, compound hot extremes significantly increased the risk of death from falls ( OR=1.19, 95% CI: 1.09-1.30), and women ( OR=1.27, 95% CI: 1.11-1.45) and the elderly age 65 and above ( OR=1.24, 95% CI: 1.12-1.39) were more sensitive to compound hot extremes. The maximum duration of compound hot extremes was 7 days, and the maximum intensity was 6.2 ℃, and the duration and intensity were proportional to the risk of death from falls. The risk of death from falls increased by 12% ( OR=1.12, 95% CI: 1.06-1.18) each day, increasing in duration after linearization. The risk of death from falls increased by 16% ( OR=1.16, 95% CI: 1.10-1.22) for each 1 ℃ increase in linearized intensity. Conclusion:Compound hot extremes increase the risk of death cases from falls.

Objective:To explore the influencing factors for skin pruritus and to construct a nomogram prediction model in peritoneal dialysis (PD) patients.Methods:It was a retrospective cross-sectional investigation study. The PD patients who were regularly followed up between July, 2023 and April, 2024 in PD center of the First Affiliated Hospital of Sun Yat-sen University were enrolled in this study. The pruritus status was evaluated by the 14-Item UP-Dial Scale. The general demographic data and clinical data were collected. The patients were divided into pruritus group and non-pruritus group according to the presence or absence of skin itching. The differences of clinical data and laboratory results were compared between the two groups. Logistic regression was used to analyze the associated factors for pruritus in PD patients. The nomogram model was constructed by R software. The receiver operating characteristic (ROC) curve analysis and the Hosmer-Lemeshow goodness-of-fit test were used to evaluate the performance of the model, and its clinical effectiveness was evaluated using the calibration curve.Results:A total of 315 PD patients were enrolled in this study, with age of (48.0±12.9) years, including 134 females (42.5%). Among them, 161 patients (51.1%) experienced skin pruritus. Of whom, 111 patients (68.9%) had mild pruritus, 34 patients (21.1%) had moderate pruritus, 16 patients (9.9%) had severe pruritus. The age ( t=-2.266, P=0.024), proportion of diabetes mellitus ( χ2=3.910, P=0.048), Charson comorbidity index ( Z=-2.458, P=0.014), blood eosinophil percentage ( Z=-2.385, P=0.017), C-reactive protein ( Z=-2.590, P=0.010), serum phosphorus ( Z=-3.233, P=0.001) and β2 microglobulin ( Z=-2.756, P=0.006) level in the pruritus group were higher than those in the non-pruritus group, and the measured glomerular filtration rate (mGFR) level ( Z=-3.708, P<0.001) of patients in the pruritus group was lower than that in the non-pruritus group. There were 262 patients in the training set and 53 patients in the validation set. The multivariate logistic regression analysis in the training set revealed that advanced age ( OR=1.032, 95% CI 1.010-1.054, P=0.004), lower mGFR ( OR=0.758, 95% CI 0.648-0.886, P<0.001), higher serum phosphorus ( OR=2.761, 95% CI 1.282-6.024, P=0.010), and elevated blood eosinophil percentage ( OR=1.098, 95% CI 1.012-1.191, P=0.025) were independent factors associated with pruritus in PD patients. The nomogram model constructed based on these indicators demonstrated good discrimination and calibration. In the training set, the area under the ROC curve ( AUC) was 0.757 (95% CI 0.699-0.816), with Hosmer-Lemeshow test χ2=4.979, P=0.760. In the validation set, the AUC was 0.779 (95% CI 0.651-0.907), and Hosmer-Lemeshow test χ2=12.938, P=0.114. Conclusions:The prevalence of skin pruritus is 51.1% in PD patient. Advanced age, lower mGFR, higher serum phosphorus and higher blood eosinophil percentage are the independent influencing factors for pruritus in PD patients. The nomogram model constructed based on these indicators shows excellent predictive performance for skin pruritus in PD patients.

Objective To explore the mechanism of Tongluo Baoshen Decoction in improving podocyte injury in rats with IgA nephropathy based on Gprc5b/NF-κB/NLRP3 pathway.Methods Totally 130 SPF-grade male SD rats were randomly divided into a normal group(n=20)and a modeling group(n=110).The IgA nephropathy model was established using a compound modeling method,and 100 modeling rats were randomly divided into model group,losartan potassium group(5 mg/kg),and Tongluo Baoshen Decoction low-,medium-,and high-dosage groups(5.3,10.6,21.2 g/kg),with 20 rats in each group.The administration group was given the corresponding dosage of medication by gavage,while the normal group and model group were given an equal amount of distilled water by gavage once a day.After 4 and 8 weeks of administration,urine samples were collected for 24 hours,and blood and kidney tissue specimens were collected.24-hour urinary protein quantification(24 h-UTP),urinary Nephrin,serum creatinine(SCr),blood urea nitrogen(BUN)and blood uric acid(BUA)contents were detected;RT-qPCR and Western blot were used to detect the expressions of G protein coupled receptor C-family 5b(Gprc5b),nuclear factor(NF)-κB p50,NOD like receptor protein 3(NLRP3),Caspase-1,interleukin(IL)-1β,Nephrin mRNA and protein in renal tissue,respectively;HE,PAS,PASM,Masson staining were used to observe the morphology of renal tissue,immunofluorescence was used to observe IgA deposition in the mesangial area of renal tissue,and transmission electron microscopy was used to observe the ultrastructure of podocytes.Results Compared with the normal group,the model group rats showed significantly increased contents of 24 h-UTP,urinary Nephrin and BUA(P<0.01),the mRNA and protein expressions of Gprc5b,NF-κB p50,NLRP3,Caspase-1 and IL-1β in renal tissue were significantly increased(P<0.01),while the mRNA and protein expressions of Nephrin were significantly decreased(P<0.01),with mild to moderate proliferation of mesangial cells in the glomerulus,increased mesangial matrix,and immunofluorescence showed clustered and linear deposition of IgA in the mesangial area,electron microscopy showed partial fusion of the foot processes.Compared with the model group,the 24 h-UTP and urinary Nephrin contents in different dosage groups of Tongluo Baoshen Decoction and the losartan potassium group after 4 and 8 weeks administration significantly decreased(P<0.01),with a decrease in BUA content in Tongluo Baoshen Decoction high-dosage group(P<0.05),the mRNA and protein expressions of Gprc5b,NF-κB p50,NLRP3,Caspase-1 and IL-1β in renal tissue of Tongluo Baoshen Decoction groups and losartan potassium group decreased(P<0.05,P<0.01),while the mRNA and protein expressions of Nephrin increased(P<0.05,P<0.01),with the proliferation of mesangial cells,the increase of mesangial matrix,the deposition of IgA in the mesangial area,and the fusion of foot processes in renal tissue were alleviated to varying degrees in different dosage groups of Tongluo Baoshen Decoction,with the most significant improvement observed in the high-dosage group.Compared with the 4-week administration,Tongluo Baoshen Decoction high-dose group showed further reductions in 24 h-UTP and urinary Nephrin contents after 8 weeks of administration(P<0.01),further decreases in the mRNA and protein expressions of Gprc5b,NF-κB p50,NLRP3,Caspase-1 and IL-1β in renal tissue(P<0.05,P<0.01),and further increases in the mRNA and protein expressions of Nephrin(P<0.01).Conclusion Tongluo Baoshen Decoction can reduce proteinuria,alleviate renal tissue lesions and improve podocyte injury in IgA nephropathy rats,and its mechanism may be related to the inhibition of Gprc5b/NF-κB/NLRP3 pathway in renal tissue.

Objective:To evaluate the application of a two-stage sequential nutritional therapy combined with functional exercise in the preoperative prehabilitation of patients with high-output intestinal fistula(HIF).Methods:A total of 164 HIF patients scheduled for definitive fistula resection in the Department of General Surgery,Eastern Theater Command General Hospital from March 2023 to March 2025 were prospectively enrolled.They were randomly assigned to a control group or an intervention group at a 1:1 ratio,with 82 patients in each group.The control group received conventional nutritional support and basic functional exercise,while the intervention group underwent a two-stage sequential nutritional therapy combined with graded functional exercise.Nutritional indicators,inflammatory markers,functional status,and postoperative recovery were compared between the two groups at 28 days before surgery,1 day before surgery,and 1,3,and 7 days after surgery.Results:On the day before surgery,the nutritional indicators in the intervention group,including albumin[(36.8±4.1)g/L],prealbumin[(213.5±42.1)mg/L],and total protein[(69.3±6.1)g/L],were all significantly higher than those in the control group[albumin(33.1±3.9)g/L,prealbumin(163.2±37.6)mg/L,total protein(63.7±5.9)g/L],with P<0.001.The energy compliance rates on the 21st day before surgery and the day before surgery in the intervention group(85.2%,92.8%)were significantly higher than those in the control group(62.5%,72.4%),with P<0.001.The 6-minute walk distance(6MWD)in the intervention group on the day before surgery and on the 7th day after surgery[(385.1±55.2)m,(346.3±48.4)m]was significantly greater than that in the control group[(315.3±60.7)m,(298.3±51.1)m],with P<0.001.On the 1st day after surgery,the inflammatory markers in the intervention group[CRP(98.7±35.2)mg/L,IL-6(45.3±12.5)pg/mL,PCT(1.2±0.5)ng/mL]were all significantly lower than those in the control group[CRP(152.4±48.6)mg/L,IL-6(89.6±25.4)pg/mL,PCT(2.8±0.9)ng/mL],with P<0.001.Additionally,the time to first ambulation after surgery[(16.8±4.2)h],time to first flatus[(52.4±14.5)h],and ICU stay duration[(3.1±1.6)d]in the intervention group were all significantly shorter than those in the control group,with P<0.001 Conclusion:The two-stage sequential nutritional therapy combined with functional exercise significantly improves the attainment of nutritional targets,suppresses systemic inflammatory response,enhances muscle reserve and exercise tolerance,and effectively shortens the postoperative recovery period in HIF patients.These findings support the use of this combined approach as a targeted and feasible model for preoperative prehabilitation,demonstrating substantial clinical application value.

Plutonium isotopes(238Pu,239Pu,240Pu and 241Pu)in the environment are important"fingerprint"nuclides in the study of nuclear activity traceability.The content of plutonium isotopes in the environmental metrics is usually very low,and the measurement of these isotopes,especially 238Pu,using mass spectrometry is seriously interfered with by the coexisting 238U.The analysis of several plutonium isotopes in soil usually requires combination of multiple measurement techniques,which leads to a long analysis time and large uncertainty in the isotope ratio.In this work,the hydrous titanium oxide(HTiO)precipitated by the hydrolysis of titanium oxydichloride(TiOCl2)under near-neutral condition was used to preconcentrate plutonium from the soil digestion solution,and the highly efficient decontamination of 238U in the sample was achieved by TK200 resin column chromatography with a decontamination factor of 108.Simulation resuts of density functional theory(DFT)showed that NH3 was considered as a promising reaction gas to eliminate the interference of 238U from 238Pu measurement using mass spectrometry due to the significant discrepancy of the chemical reactivity of U+and Pu+with the reactive gas NH3.Experiments confirmed that by optimizing the flow rates of collision gas(He)and reaction gas(NH3),the interference of 238U could be effectively suppressed,and the decontamination factor of 238U was 104.Combined with chemical separation,the overall decontamination factor of 238U could reach 1012 by using the developed method.By combining chemical separation and tandem quadrupole inductively coupled plasmon-mass spectrometry(ICP-MS/MS)measurement,the simultaneous determination of four ultra-trace plutonium isotopes in soil was realized,and the detection limit of plutonium isotopes was at the femtogram level.Analysis of the international standard reference materials(NIST-SRM-4357 and IAEA-384)showed that the established method could be successfully used for the accurate analysis of ultra-trace four plutonium isotopes(238Pu,239Pu,240Pu and 241Pu)in soil samples.
