Background Although current evidence suggests a link between outdoor air pollution and depressive symptoms, the effect of solid fuel use (a significant indoor air pollutant) on depressive symptoms in China's rural middle-aged and elderly population remains poorly understood. Objective To explore the association between solid fuel use for cooking and depressive symptoms among middle-aged and elderly people in rural areas of China, and to provide a basis for the prevention and control of depressive symptoms among residents in rural areas. Methods Data were obtained from the 2020 China Family Panel Studies (CFPS), depressive symptoms were assessed using 8-item Center for Epidemiologic Studies Depression Scale (CES-D), and cooking fuel type was self-reported. Subsequently, two-level binary unconditional logistic regression models were fitted to assess the impact of solid fuel use for cooking on depressive symptoms. Results A total of 7991 participants aged 45 years and older [mean age (58.52±9.18) years] were included in the study, with a mean CES-D score of 6.07±4.48 and a mean positive depressive symptoms rate of 34% (40.54% in the solid fuel group and 30.81% in the clean fuel group, χ²=74.40, P<0.001). After controlling for potential confounding covariates, rural middle-aged and elderly residents in the solid fuel group had a higher risk of reporting depressive symptoms than those in the clean fuel group (OR=1.36, 95%CI: 1.20-1.54), an association that was unaffected by participant characteristics and was positive across age and gender groups. Conclusion There is a positive association between solid fuel use for cooking and depressive symptoms in middle-aged and elderly people in rural areas of China. It is recommended that rural areas promote the upgrading of stoves through the installation of ventilation equipment or the switch from solid cooking fuel to clean fuel. This approach is directed toward reducing exposure to household air pollution, alleviating the prevalence of depression among middle-aged and elderly residents in vast rural areas, and enhancing their mental health.

OBJECTIVE: To observe the effect of heat-sensitive moxibustion on the quality of life in the elderly patients with malignant tumor based on palliative treatment. METHODS: A total of 100 elderly patients with malignant tumor were randomly divided into an observation group (50 cases, 3 cases dropped out) and a control group (50 cases, 4 cases dropped out). The conventional palliative treatment was performed in the control group. On the basis of conventional palliative treatment, heat-sensitive moxibustion was added at Shenque (CV8) and Zhongwan (CV12) in the observation group, once a day, 5 times a week, one course of treatment was composed of 2 weeks, and 2 consecutive courses of treatment were given. In the observation group, 15 patients voluntarily continued heat-sensitive moxibustion treatment, which was collected in the sub-observation group No.1, these patients were treated 3 times a week and for 6 months consecutively. Using the propensity score matching method, 15 patients who only completed 2 courses of treatment were assigned into the sub-observation group No.2. Before and after treatment, the scores of European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30), the Karnofsky performance status (KPS), and the anorexia/cachexia subscale-12 (A/CS-12), as well as the immune indexes (the contents of serum immune globulin [Ig]G, IgA, IgM and complements C3 and C4) were observed in the patients of the observation group and the control group. The monthly survivals were recorded in the two sub-observation groups after 6 months of treatment completion. The coordination was analyzed on the score of deqi scale of heat-sensitive moxibustion at the probing stage before treatment and the change in the score of EORTC QLQ-C30 before and after treatment in the patients of the observation group. RESULTS: After treatment, except the score related to the financial difficulties, the score of every items in EORTC QLQ-C30 was greater than that before treatment in the observation group (P<0.05); the scores for overall health, nausea/vomiting, pain, short breath, constipation and diarrhea of the scale were higher than those before treatment in the control group (P<0.05). The score for each item of the scale in the observation group was higher when compared with that in the control group, except the score for financial difficulties (P<0.05). After treatment, KPS score increased in the observation group when compared with that before treatment (P<0.05), and the score was higher than that of the control group (P<0.05). After treatment, A/CS-12 score was elevated in comparison with that before treatment in each group (P<0.05), and the score in the observation group was higher than that of the control group (P<0.05). After treatment, in the observation group, the contents of serum IgG, IgA and IgM, and C3 and C4 increased in comparison with those before treatment (P<0.05); and in the control group, the contents of serum IgG, C3 and C4 were declined (P<0.05). After treatment, the contents of serum IgG, IgA and IgM, and C3 and C4 in the observation group were higher than those in the control group (P<0.05). After 6 months of treatment completion, the survival rate in the sub-observation group No.1 was higher than that of the sub-observation group No.2 (P<0.05). In the observation group, the positive coordination was presented between the score of deqi scale of heat-sensitive moxibustion and the change in the score of EORTC QLQ-C30 in the observation group (r>0, P<0.001). CONCLUSION On the basis of palliative treatment, heat-sensitive moxibustion can improve the quality of life, appetite and the immunity of the elderly patients with malignant tumor. Consecutive long-term moxibustion is contributed to prolonging the life span. The stronger deqi is felt during moxibustion delivery, the more significant the therapeutic effect is obtained.

The quality of drugs is a crucial premise for ensuring the safety and effectiveness of clinical medication, while quality control during the pharmaceutical process directly affects the quality and consistency of the final product formulation. However, there is a lack of a comprehensive and scientific system for assessing and optimizing the quality control level during the manufacturing process in the field of drug quality control. Therefore, this study proposed the concept of "pharmaceutical process omics", clarified its advantages in guiding drug production, and explored in depth the research approaches, diverse analytical techniques, and broad range of applications in drug quality control. In addition, this study anticipated the broad application prospects of pharmaceutical process omics in the field of drug quality control, aiming to provide a scientific basis for the development of pharmaceutical process quality control standards.

This study investigates the therapeutic effect and underlying mechanism of Compound Ziyin Granules(CZYG) on postmenopausal osteoporosis(PMOP) induced by bilateral ovariectomy in rats. Six-month-old female SD rats were randomly divided into sham-operated(sham) group, ovariectomy(OVX) model group, high-, medium-, and low-dose CZYG groups, and alendronate sodium(AS) group. After 30 days of model establishment, treatment was administered by gavage once daily for 8 weeks, followed by sample collection. Enzyme-linked immunosorbent assay(ELISA) was used to measure serum levels of calcium ions, alkaline phosphatase(AKP), estrogen(E_2), osteoprotegerin(OPG), osteocalcin(BGP), tartrate-resistant acid phosphatase(TRAP), and type Ⅰ procollagen N-terminal propeptide(PINP). Hematoxylin-eosin(HE) staining was used to observe the histopathological changes in the femurs of rats, while micro-computed tomography(micro-CT) was used to analyze the microstructure of the distal femur. Western blot analysis was performed to measure the expression levels of bone metabolism-related proteins, including wingless-type MMTV integration site family member 2(Wnt2), β-catenin, low-density lipoprotein receptor-related protein 5(LRP5), glycogen synthase kinase-3β(GSK-3β). The mRNA expression levels of Wnt2, β-catenin, LRP5, GSK-3β, p-GSK-3β were determined by quantitative real-time PCR(qRT-PCR). Thirty days after bilateral ovariectomy, compared to the sham group, the OVX group showed significant increases in body weight and significant decreases in uterine coefficient. After 8 weeks of treatment, compared to the OVX group, CZYG(medium and high doses) and AS reduced body weight, with high-dose CZYG and AS significantly increasing the uterine coefficient. Serum levels of AKP and TRAP were significantly elevated, while levels of calcium, E_2, BGP, and OPG were significantly decreased in the OVX group. Compared to the OVX group, CZYG and AS significantly reduced serum levels of AKP and TRAP, while high-dose CZYG and AS notably increased the levels of E_2, BGP, OPG, and PINP. Micro-CT and HE staining results indicated that CZYG(medium and high doses) and AS significantly increased bone tissue volume, trabecular number, bone mineral density, and improved the microstructure of the femur. Compared to the OVX group, high-dose CZYG and AS significantly upregulated the protein and mRNA expression levels of Wnt2, β-catenin, and LRP5, and downregulated the phosphorylation level of p-GSK-3β. These results suggest that CZYG can improve PMOP by promoting estrogen secretion, improving bone metabolism indicators, increasing trabecular number and bone mineral density. Its mechanism may be related to the regulation of the Wnt/β-catenin signaling pathway.

OBJECTIVE: Hepatocellular carcinoma (HCC) is sensitive to ferroptosis, a new form of programmed cell death that occurs in most tumor types. However, the mechanism through which ferroptosis modulates HCC remains unclear. This study aimed to investigate the oncogenic role and prognostic value of FANCD2 and provide novel insights into the prognostic assessment and prediction of immunotherapy. METHODS: Using clinicopathological parameters and bioinformatic techniques, we comprehensively examined the expression of FANCD2 macroscopically and microcosmically. We conducted univariate and multivariate Cox regression analyses to identify the prognostic value of FANCD2 in HCC and elucidated the detailed molecular mechanisms underlying the involvement of FANCD2 in oncogenesis by promoting iron-related death. RESULTS: FANCD2 was significantly upregulated in digestive system cancers with abundant immune infiltration. As an independent risk factor for HCC, a high FANCD2 expression level was associated with poor clinical outcomes and response to immune checkpoint blockade. Gene set enrichment analysis revealed that FANCD2 was mainly involved in the cell cycle and CYP450 metabolism. CONCLUSION To the best of our knowledge, this is the first study to comprehensively elucidate the oncogenic role of FANCD2. FANCD2 has a tumor-promoting aspect in the digestive system and acts as an independent risk factor in HCC; hence, it has recognized value for predicting tumor aggressiveness and prognosis and may be a potential biomarker for poor responsiveness to immunotherapy.

OBJECTIVE: To study the results, re-donation situation and characteristics of single-reagent reactive blood donors who were put into the reentry strategy in Wuhan area, explore the rationality and effectiveness of the current reentry strategy, and provide data support for the improvement of the reentry process of blood donors. METHODS: From January 2020 to December 2023, blood donors who conform the reentry criteria and voluntarily applied for returning to Wuhan Blood Center were tested and the results were analyzed. According to the reentry strategy, serological testing and nucleic acid testing were carried out in parallel, serological testing was performed by ELISA with reagents from two different manufacturers, and the primary reactive samples were tested by double-well retest, and HBV/HCV/HIV nucleic acid detection was performed by RT-PCR with an individual donor test mode. Supplementary HBcAb testing was applied for HBV single reagent reactivity by chemiluminescence method. Supplementary TP-WB testing was applied for returning blood donors with repeated TP single reagent reactivity. If returning blood donors with HIV single reagent reactivity were repeated single reagent reactivity, the samples were sent to local CDC for confirmatory test. RESULTS: 7 098 blood donors were qualified for reentry, 716 donors voluntarily applied for reentry, 436 donors successfully reentry, 251 donors entered the next round, 29 donors could not reentry. The reentry rates for the past four years were 66.67%（42/63）, 54.73%（81/148）, 60.71%（136/224） and 62.99%（177/281）, respectively. Up to December 31, 2023, 275 donors donated blood again, and the donation rates for past four years were 76.19%（32/42）, 72.84%（59/81）, 61.76%（84/136） and 56.50%（100/177）, respectively. After donating blood, 31 donors were disqualified again by blood screening and subjected to permanent deferral. The results of returning to the team had statistical differences in reentry items, educational level, age, and marriage（P < 0.05）. CONCLUSION The current reentry strategy adopted by the blood donation and supply institution can effectively retain part of blood donors, reduce the negative emotions of blood donors and increase blood resources.

Background: Diabetic macrovascular and microvascular complications often coexist and may share similar risk factors and pathological pathways. We aimed to investigate whether 10-year atherosclerotic cardiovascular disease (ASCVD) risk, which is commonly assessed in diabetes management, can predict incident diabetic nephropathy (DN) and retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). Methods: This prospective cohort study enrolled 2,891 patients with clinically diagnosed T2DM who were free of ASCVD, nephropathy, or retinopathy at baseline in the Guangzhou (2017–2022) and Shaoguan (2019–2021) Diabetic Eye Study in southern China. The 10-year ASCVD risk was calculated by the Prediction for ASCVD Risk in China (China-PAR) equations. Multivariable- adjusted Cox proportional hazard models were developed to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). The area under the receiver operating characteristic curve (AUC) was used to evaluate predictive capability. Results: During follow-up, a total of 171 cases of DN and 532 cases of DR were documented. Each 1% increment in 10-year ASCVD risk was associated with increased risk of DN (pooled HR, 1.122; 95% CI, 1.094 to 1.150) but not DR (pooled HR, 0.996; 95% CI, 0.979 to 1.013). The model demonstrated acceptable performance in predicting new-onset DN (pooled AUC, 0.670; 95% CI, 0.628 to 0.715). These results were consistent across cohorts and subgroups, with the association appearing to be more pronounced in women. Conclusion Ten-year ASCVD risk predicts incident DN but not DR in our study population with T2DM. Regular monitoring of ASCVD risk in routine diabetes practice may add to the ability to enhance population-based prevention for both macrovascular and microvascular diseases, particularly among women.
