Objective To investigate the epidemiological characteristics of lymphoma mortality and potential years of life lost among Wuhan residents, and to provide a scientific basis for the prevention and control of lymphoma. Methods Data on lymphoma deaths among residents in Wuhan from 2010 to 2019 were collected from the population-based Wuhan Mortality Surveillance System. Joinpoint regression model was used to evaluate the trends in age-standardized mortality rates and potential years of life lost due to lymphoma among the residents of different ages and genders. Potential years of life lost rate was used to assess the disease burden. Results There were 4 055 deaths (2481in male and 1 574 in female) from major kidney diseases in Wuhan residents between 2010 to 2019, with an age-standardized mortality rate of 5.11/100 000. The mortality rate of major kidney diseases showed an upward trend with increasing age. Between 2010 and 2019, the age-standardized mortality rates of the multiple myeloma and non-Hodgkin lymphoma were significantly increased (APC=6.924%, APC=1.407%, P＜0.05), and the potential years of life lost rate of non-Hodgkin lymphoma in female were significantly increased (APC=7.935%，P＜0.05). Conclusion From 2010 to 2019, the mortality rate of lymphoma among residents of Wuhan City shows an upward trend, especially for multiple myeloma and non-Hodgkin lymphoma. The disease burden of multiple myeloma shows an increasing trend in the female population, suggesting the need to take corresponding preventive and control measures.

The Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines （hereinafter referred to as the Guidelines） is first specialized in the field of drug safety for oral Chinese patent medicines （OCPMs） in China. Rooted in China's healthcare context， the Guidelines address the unique usage patterns and risk characteristics of OCPMs， filling a regulatory gap in the pharmacovigilance framework specific to this category. To facilitate accurate understanding and effective implementation of the Guidelines， and to promote the standardized development of pharmacovigilance practices for OCPMs， this study offered a systematic interpretation based on its three core components. In the domain of risk monitoring and reporting， the paper analyzed the rationale for multi-source information integration and clarified the criteria for identifying key products and target populations for intensive monitoring. Regarding risk assessment， the Guidelines were examined from three dimensions of formulation components， medication behaviors， and population to address complex safety issues arising from medicinal constituents， irrational use， and individual susceptibility. In the area of risk control， the analysis focused on context-based interventions and dynamic closed-loop management strategies， exploring practical pathways to shift from passive response to proactive risk mitigation. Furthermore， this paper evaluated the applied value of the Guidelines and identified implementation challenges， such as insufficient capacity at the primary-care level and limited digital infrastructure. In response， the study proposed optimization strategies including establishing a dynamic updating mechanism， strengthening training at the grassroots level， and incorporating artificial intelligence to enhance pharmacovigilance capacity. This interpretation aims to provide actionable insights for marketing authorization holders （including manufacturers）， pharmaceutical distributors， healthcare institutions， and research organizations， ultimately supporting the establishment and refinement of a full lifecycle pharmacovigilance system for OCPMs.

Background: Adrenocortical hormones, particularly 11-oxygenated androgens, are pivotal in female reproductive health and fertility. Standardized detection kits and population-specific reference intervals are lacking in China, hindering related clinical applications. Methods: A HPLC-tandem mass spectrometry (HPLC-MS/MS) pipeline was developed, rigorously validated, and applied to simultaneously quantify corticosterone, cortisone, cortisol, 18-OH cortisol, androstenedione (A4), 11β-hydroxyandrostenedione (11-OH A4), dehydroepiandrosterone, and dehydroepiandrosterone sulfate in serum samples from 455 reproductive-aged women (18–45 yrs) in Guangxi, China. Age-dependent concentration trends were analyzed, and reference intervals stratified by age (2.5th to 97.5th percentiles) were established. Correlations with body-composition metrics, ethnicity, and the menstrual cycle were investigated. Results: The HPLC-MS/MS method demonstrated high precision (intra- and inter-assay CVs < 15%), accuracy, and sensitivity. All eight hormones exhibited significant age-related declines (P < 0.001 for seven hormones; P = 0.001 for 11-OH A4). Notably, 11-OH A4 levels were significantly lower in the 35–45-yr (3.05 nmol/L) and 25–34-yr (3.09 nmol/L) age groups than in the 18–24-yr (3.57 nmol/L) age group, whereas no significant difference was observed between the 35–45-yr and 25–34-yr age groups. Weak negative correlations were observed between the body mass index and corticosterone and cortisone levels, whereas ethnicity and the menstrual cycle showed no significant associations with hormone levels. Conclusions We developed an HPLC-MS/MS-based method for simultaneously quantifying eight adrenocortical hormones, including 11-OH A4, and defined age-specific reference intervals for reproductive-aged Chinese women. These findings advance the clinical utility of adrenocortical hormones in diagnosing and managing reproductive disorders.

Objective To explore the value of carotid pulse wave combined with urinary transferrin(TRF)and β2-microglobulin(β2-MG)in the evaluation of renal injury in patients with hyperten-sive nephropathy.Methods A total of 30 patients with hypertensive nephropathy,30 patients with simple hypertension and 90 patients with non-hypertensive nephropathy who were admitted to our hospital between May 2021 and April 2024,and 30 healthy individuals(control group)who taking physical examination during same period were enrolled and assigned into corresponding groups,respectively.According to the severity of renal injury,the 120 patients from the hyperten-sive nephropathy group and non-hypertensive nephropathy group were divided into normal group(28 cases),mildly injured group(36 cases),moderately injured group(31 cases)and severely in-jured group(25 cases).The carotid pulse wave indicators[pulse wave velocity at beginning of the systole(PWV-BS),pulse wave velocity at ending of the systole(PWV-ES)],and urinary TRF and β2-MG levels were detected and compared in above groups.ROC curves were plotted to ana-lyze the diagnostic values of these indicators in hypertensive nephropathy.The relationship be-tween the above indicators and the severity of renal injury was analyzed with sequential multivari-ate logistics regression analysis.Results There were significant differences in PWV-BS,PWV-ES,and urinary TRF and β2-MG levels among the hypertensive nephropathy group,non-hyperten-sive nephropathy group,hypertension group and control group(P＜0.01).ROC curve analysis showed that the AUC value of the four indictors combined together in the diagnosis of hyperten-sive nephropathy was 0.907,which was statistically greater than that of single indicator alone(0.774,0.743,0.728,0.749,P＜0.01).Obvious differences were also observed in PWV-BS,PWV-ES,and urinary TRF and β2-MG levels among the severely,moderately and mildly injured groups and normal group(P＜0.01).Sequential multivariate logistics regression analysis indicated that PWV-BS(OR=1.824,95％CI:1.272-2.616,P=0.001),PWV-ES(OR=1.910,95％CI:1.268-2.877,P=0.002),and urinary TRF(OR=2.442,95％CI:1.485-4.018,P=0.001)and β2-MG levels(OR=2.807,95％CI:1.580-4.984,P=0.001)were influencing factors of renal injury severity in the renal injured patients.Conclusion Carotid pulse wave combined with urinary TRF and β2-MG can be applied in auxiliary diagnosis of hypertensive nephropathy,and they are correla-ted with the severity of renal injury.

Objective To explore the clinical efficacy of percutaneous ureteral flexible ureteral holmium laser lithotripsy(PNHLL)and single ureteral flexible percutaneous nephrolithotomy(ECIRS)in the treatment of complex kidney stones.Methods The clinical data of 103 patients with complex renal calculi admitted to our hospital from January 2015 to March 2023 were retrospectively analyzed.According to the surgical methods,they were divided into PNHLL group(53 cases)and ECIRS group(50 cases).The perioperative related indicators,stone clearance rate,renal function,stress response and postoperative complications were compared between the two groups.Results The operation time of ECIRS group was longer than that of PNHLL group[(97.62±19.52)min vs.(72.43±14.48)min],and the success rate of stone removal was higher than that of PNHLL group[92.00％(46/50)vs.75.47％(40/53)](P＜0.05).After operation,the levels of blood urea nitrogen(BUN)[(15.44±3.08)mmol/L vs.(17.21±3.44)mmol/L],cystatin C(CysC)[(611.85±34.22)μg/L vs(637.42±35.41)μg/L],creatinine(Scr)[(77.52±8.64)μmol/L vs.(81.63±9.07)μmol/L],superoxide dismutase(SOD)[(108.64±7.24)U/ml vs.(115.27±7.68)U/ml],prostaglandin E2(PGE2)[(162.41±18.05)μmol/L vs.(175.48±19.47)μmol/L],nitric oxide(NO)[(74.61±8.29)μmol/L vs.(78.58±8.73)μmol/L]and cortisol(Cor)[(188.64±29.02)nmol/L vs.(212.42±32.68)nmol/L]in ECIRS group were lower than those in PNHLL group(P＜0.05).Conclusion Compared with PNHLL,ECIRS has a higher success rate of stone clearance in the treatment of complex renal calculi,and has less renal function and postoperative traumatic stress response,which is beneficial to postoperative recovery.

Objective:To investigate the regulatory effects of transcutaneous auricular vagus nerve stimulation (taVNS) on functional connectivity (FC) of thalamic subregions in patients with premenstrual syndrome (PMS).Methods:This study was a cross-sectional investigation. Clinical, laboratory, and imaging data were retrospectively collected from 56 PMS patients (PMS group) and 66 healthy controls (control group) recruited from various universities and hospitals in Nanning between November 2021 and June 2024. Resting-state functional MRI (fMRI) data and fMRI data during taVNS immediate stimulation (2 Hz, 25 Hz) were acquired from subjects during their late luteal phase. Using thalamic subregions (anterior thalamic nucleus, lateral nucleus, ventral nucleus, medial nucleus, central nucleus, posterior nucleus) as seeds, two-sample t-tests or paired t-tests were employed to analyze alterations in thalamic subregion FC in PMS patients and the regulatory effects of taVNS on these changes. Independent samples t-test were used to compare the differences in clinical and laboratory indicators between the PMS group and the control group. The relationship between taVNS regulation of thalamic subregion FC in PMS patients and thalamic internal functional connectivity were analyzed using mediation effect analysis. Results:Compared to the control group, patients in the PMS group showed increased scores on the Daily Record of Severity of Problems, Pittsburgh Sleep Quality Index, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Hamilton Anxiety Rating Scale 17, and Hamilton Depression Rating Scale 14 during the late luteal phase ( P<0.05). At baseline, PMS patients exhibited higher FC between the left thalamic lateral nucleus and the left insula, and lower FC between the left medial nucleus, posterior nucleus, and ventral nucleus of the thalamus and the right middle frontal gyrus (MFG) compared to the control group (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). During 2 Hz taVNS immediate stimulation in PMS group, FC between the left thalamic medial nucleus, posterior nucleus, ventral nucleus and the right MFG, as well as the FC between the left thalamic ventral nucleu and the left MFG increased compared to baseline levels; meanwhile, FC between the left thalamic posterior nucleus, ventral nucleus and the left insula decreased compared to baseline levels (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). During 25 Hz taVNS immediate stimulation, the FC between the left thalamic ventral nucleus and the right MFG decreased compared to the baseline level (GRF corrected, voxel-level P<0.001, cluster-level P<0.05). Mediation effect analysis showed that the FC between the left thalamic posterior nucleus and the left lateral nucleus mediated part of the association between the FC of the left lateral thalamic nucleus-left insula and the FC of the left ventral thalamic nucleus-left putamen/insula; there were significant direct effects between the FC of the left lateral thalamic nucleus-the left posterior nucleus and FC of the left lateral thalamic nucleus-the left insula, as well as between the FC of the left ventral thalamic nucleus-the left MFG and FC of the left ventral thalamic nucleus-the right MFG. Conclusions:taVNS can modulate abnormal FC of the left thalamic subregions in PMS patients, restoring it toward normalization. The regulatory effects of 2 Hz stimulation are more pronounced than those of 25 Hz stimulation. This modulation primarily operates through two pathways: the left thalamic lateral nucleus-left insula-left thalamic ventral nucleus pathway and the left MFG-left thalamic ventral nucleus-right MFG.
