OBJECTIVE To investigate the application status of prescription pre-review systems in healthcare institutions of Yunnan province, evaluate their system functions and management capabilities, and provide a practical basis for promoting rational drug use. METHODS A questionnaire survey was conducted among public healthcare institutions at or above the secondary level in Yunnan province to investigate the deployment status of the systems. A capability maturity assessment framework was constructed, encompassing 6 dimensions and 39 indicators, including real-time prescription review, prescription correlation review, rule setting, evidence-based information support, prescription authority management, and system operation management. This framework was then used to evaluate the institutions that had implemented the pre-review systems. RESULTS A total of 100 valid questionnaires were collected, with 37 institutions having adopted prescription pre-review systems, mainly tertiary hospitals. The system predominantly adopted a modular architecture and was embedded into the hospital information system through application programming interfaces and middleware, providing certain capabilities for real-time prescription risk identification. Evaluation results indicated that basic functions such as reviewing indications, contraindications, and drug compatibility performed well, while deficiencies remained in functions related to parenteral nutrition prescription, review of drug dosage for specific diseases, individual patient characteristic recognition, and rule setting. Moreover, the construction of review centers and establishment of management systems were also not well-developed. CONCLUSIONS The overall application rate of prescription pre-review systems in Yunnan province remains low. System functions and management mechanisms require further improvement. It is recommended to enhance information infrastructure in lower-level institutions and explore regionally unified review models to promote standardized and intelligent development of prescription review practices.

Objective: To analyze the implementation status of the “Three-Exemptions” policy for voluntary blood donation in China by taking Shandong Province as a case study, explore the sociodemographic characteristics of policy beneficiaries and the distribution differences in blood donation frequencies, so as to provide practical references for improving the honor incentive system of voluntary blood donation and stabilizing the blood donation team. Methods: Excel was used to sort out and summarize the policy documents from 31 provincial-level administrative regions of China (excluding Hong Kong, Macao and Taiwan), and its implementation models, temporal characteristics and implementation basis were analyzed. Using 238 193 policy beneficiaries in Shandong Province as the research objects, Stata was adopted for descriptive statistical analysis of sociodemographic characteristics including gender, age, educational background and occupation. The Mann-Whitney U test and Kruskal-Wallis H test were performed to compare the distribution differences of blood donation frequencies among populations with different characteristics. Results: The “Three Exemption” policy has been implemented in 29 provinces nationwide, forming five differentiated implementation models. Specifically, 45.16% of the regions adopted province-wide unified implementation, 32.26% adopted partial prefecture-level city implementation, 12.90% adopted partial clause implementation, 3.23% adopted encouraging implementation, and 6.45% had not implemented the policy. The period from 2023 to 2026 witnessed the concentrated promotion of the policy. In Shandong Province, the beneficiaries were mainly males (82.08%), middle-aged individuals aged 40-60 years (71.78%), groups with junior and senior high school education (56.57%), and staff employees (30.60%). The distribution of blood donation frequencies showed that nearly 60% (56.95%) of the beneficiaries had donated blood 20 to 29 times. Statistically significant differences in donation frequency distributions were observed across genders, age groups, educational backgrounds, and occupations (all P<0.05). Further analysis revealed that the proportion of males with 40 or more blood donations was higher than that of females (24.32% vs 15.60%), while females had a higher proportion of 20-29 blood donations than males (65.98% vs 54.99%). With the increase of age, the proportion of those with 20-29 blood donations gradually decreased, whereas the proportion of those with≥40 blood donations gradually increased. Conclusion: The coverage of the “Three Exemptions” policy for voluntary blood donation in China continues to expand. However, there is still room for optimization in terms of policy implementation standards, population structure adaptation and incentive gradient design. Future efforts should strengthen national top-level design to balance regional development gaps. Moreover, hierarchical and targeted incentive and publicity strategies combined with population structural characteristics should be implemented to enhance public enthusiasm for voluntary blood donation.

ObjectiveTo investigate the effects of Liuwei Dihuangwan on mammalian target of rapamycin (mTOR)-mediated synaptic plasticity in the prefrontal cortex-hippocampus circuit in the rat model of valproic acid (VPA)-induced autism spectrum disorder (ASD) and to explore its potential mechanism for reducing behavioral abnormalities in ASD rats. MethodsThirteen SD pregnant rats were randomized into the VPA group (10 rats) and the control group (3 rats). On gestational day 13, the VPA group was intraperitoneally injected with VPA solution (600 mg·kg-1), while the control group was injected with an equal volume of normal saline. Male pups of 21 days old from both groups underwent behavioral tests to screen the ASD model rats (32 rats). These rats were then randomly assigned to the model (distilled water), vitamin D (1 480 U·kg-1), low-dose (0.75 g·kg-1) Liuwei Dihuangwan, and high-dose (1.5 g·kg-1) Liuwei Dihuangwan groups, and normal male pups were selected as the blank group (distilled water), with 8 rats in each group. Each group was treated with the corresponding drug or an equal volume of distilled water via gavage daily. After drug administration, behavioral tests were conducted again, followed by anesthesia and tissue collection. Nissl staining was carried out to observe the morphological changes of neurons in the prefrontal cortex and hippocampus. Transmission electron microscopy was used to observe changes in hippocampal synaptic structure. Immunohistochemistry and Western blot were employed to determine the expression of mTOR, phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) in the prefrontal cortex, as well as synaptophysin-1 (SYP-1), postsynaptic density 95 (PSD95), and N-methyl-D-aspartate receptors (NMDARs) in the hippocampus. ResultsCompared with the control group, the model group exhibited severe growth retardation and developmental deformities, with abnormal behavioral performance and pathological damage to neurons and synapses in the prefrontal cortex and hippocampus. Compared with the model group, all treatment groups showed reduced behavioral abnormalities and pathological damage to neurons and synapses in the prefrontal cortex and hippocampus, with the most significant effects in the high-dose Liuwei Dihuangwan group. Immunohistochemistry and Western blotting results showed that compared with the control group, the model group exhibited significantly increased protein levels and phosphorylation ratios of p-mTOR, p-Akt, and p-PI3K in the prefrontal cortex (P<0.05, P<0.01), and decreased protein levels of SYP-1 and PSD95 and increased protein level of NMDARs in the hippocampus (P<0.01). Compared with those in the model group, the protein levels of p-mTOR, p-Akt, and p-PI3K in the prefrontal cortex decreased in the vitamin D and high-dose Liuwei Dihuangwan groups (P<0.05), and the p-mTOR/mTOR, p-Akt/Akt, and p-PI3K/PI3K ratios in the prefrontal cortex declined in the vitamin D group (P<0.05). The high-dose Liuwei Dihuangwan group showed a reduction in p-PI3K/PI3K ratio (P<0.05). The protein level of SYP-1 and PSD95 in the hippocampus increased in the vitamin D, low-dose Liuwei Dihuangwan, and high-dose Liuwei Dihuangwan groups (P<0.05, P<0.01), while the protein level of NMDARs decreased in the vitamin D and high-dose Liuwei Dihuangwan groups (P<0.01). ConclusionLiuwei Dihuangwan significantly reduces VPA-induced ASD-like behaviors and enhances the regeneration and repair of neurons in the prefrontal cortex and synaptic structures in the hippocampus by downregulating of PI3K/Akt/mTOR expression in the prefrontal cortex, upregulating SYP-1 and PSD95 expression in the hippocampus, and inhibiting NMDARs expression.
4.Applications of Nano Drug Delivery Systems in The Diagnosis and Treatment of Cerebral Ischemia-reperfusion Injury
Progress in Biochemistry and Biophysics 2026;53(10):2609-2628
Acute ischemic stroke is a major cerebrovascular disease with high disability and mortality rates. Although clinical intravenous thrombolysis and mechanical thrombectomy can restore blood perfusion in ischemic brain tissue, they are highly likely to induce secondary cerebral ischemia-reperfusion injury (CI/RI) after blood reperfusion. The pathological process of CI/RI is extremely complex, presenting as a cascading damage network where oxidative stress outbreaks, mitochondrial dysfunction, excessive neuroinflammation, disruption of the blood-brain barrier structure, imbalance of the neurovascular unit homeostasis, and multiple programmed cell death pathways are intertwined. Various pathological links positively feedback on each other, continuously expanding the scope of cerebral infarction, causing irreversible apoptosis of neurons, and ultimately leading to long-term neurological deficits. At present, commonly used neuroprotective small-molecule drugs in clinical practice, such as edaravone and butylphthalide, have several drawbacks. These include poor blood-brain barrier penetration and low drug enrichment concentration at the lesion site; insufficient lesion targeting and obvious off-target toxic side effects of systemic administration; a narrow treatment time window and the inability of single-target drugs to block multi-pathway cross-linked damage. These limitations have made it difficult to translate a large number of basic research findings into clinical applications. The nanodelivery system, with its four core advantages of tunable physicochemical properties, flexible surface functionalization, integration of multifunctional modules, and response to the pathological microenvironment, can efficiently cross the damaged blood-brain barrier through endocytosis, accumulate directionally in the ischemic penumbra, and release drugs in a targeted manner in response to characteristic signals such as low pH, high reactive oxygen species, and high matrix metalloproteinases at the lesion site. This provides a new technical approach for achieving both precise treatment and early molecular diagnosis of CI/RI. This paper systematically reviews the core pathological mechanisms of CI/RI and outlines six major mainstream nanodrug delivery systems, namely polymer-based (synthetic polymers, natural biopolymers), lipid-based (traditional lipid carriers, intelligent lipid nanoparticles), inorganic nanozyme materials, cell membrane biomimetic nanocarriers, natural extracellular vesicles, and carrier-free self-assembled nanoformulations. It compares the material construction characteristics, brain-targeting mechanisms, neuroprotective advantages, and inherent limitations of each type of carrier. It also elaborates on the recent cutting-edge research progress of nanodrug delivery systems in three directions: targeted single-pathway intervention, multi-pathological pathway collaborative blockade, and multimodal visual imaging diagnosis of CI/RI. Moreover, it analyzes the current core practical bottlenecks restricting the translation of nanodrugs from the laboratory to clinical applications, including long-term in vivo biosafety risks, insufficient lesion targeting accuracy, great difficulty in large-scale and standardized preparation, and the lack of a unified evaluation system for drug efficacy and safety. By integrating frontier research cases of co-delivery of multimodal imaging probes and neuroprotective drugs, this paper distinguishes the functional differences between single-therapeutic nanocarriers and integrated diagnosis and treatment platforms, and clarifies how imaging modules achieve precise lesion localization and dynamic disease course monitoring, providing a clear development context for the research on visual and precise intervention of stroke. From the cross-disciplinary perspectives of biochemistry, materials science, and pharmacy, this paper prospects the development ideas of the next-generation intelligent, highly biocompatible, and integrated diagnosis and treatment nanoplatforms, as well as the promotion of the combined application of nanodelivery technology with clinical thrombolysis and thrombectomy protocols. It is expected to provide systematic and comprehensive theoretical support for the structural optimization, basic research and development, and clinical translation of novel nanodrugs for cerebral ischemia-reperfusion injury.

Post-orgasmic illness syndrome (POIS) is a rare condition characterized by the rapid onset of extreme fatigue, flu-like symptoms, difficulty concentrating, depression, nasal congestion, rhinorrhea, itchy eyes, and other physical and psychological discomforts following ejaculation. This report presents the outcomes of two patients with POIS who underwent a two-year course of autologous seminal plasma subcutaneous cluster immunotherapy. Treatment efficacy was assessed using methods such as the symptom Visual Analogue Scale (VAS), the Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ)-70, and the Short Form 36 Health Survey (SF-36). The results suggest that autologous seminal plasma subcutaneous cluster immunother-apy may be a safe and effective therapeutic approach for POIS.

Background The Inner Mongolia Autonomous Region is a vast area with a wide array of ecological environments, resulting in considerable regional variations in air pollution characteristics. Current research is limited by a scarcity of systematic, region-wide studies and risk assessments. Objective To assess the health risks associated with inhalation exposure to nine heavy metal and metalloid elements in atmospheric fine particulate matter (PM2.5) for the population of the Inner Mongolia Autonomous Region. Methods From the 10th to the 16th of each month throughout 2023, atmospheric PM2.5 samples were collected at designated monitoring sites in 12 leagues (cities) across the Inner Mongolia Autonomous Region to analyze the characteristics and trends in concentration. The health risk assessment model developed by the United States Environmental Protection Agency was employed to evaluate both the non-carcinogenic and carcinogenic risks associated with the heavy metal elements beryllium (Be), cadmium (Cd), chromium (Cr), hydrargyrum (Hg), plumbum (Pb), manganese (Mn), and nickel (Ni) and the metalloid elements stibium (Sb) and arsenic (As). Results In 2023, a total of

BACKGROUND:
The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China.
METHODS:
This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences.
RESULTS:
Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n = 278] vs . 43.7% [ n = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses.
CONCLUSION
This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Journal of Integrative Medicine 2025;23(6):630-640
BACKGROUND:
The use of inserted sham acupuncture as a placebo in randomized controlled trials (RCTs) is controversial, because it may produce specific effects that cause an underestimation of the effect of acupuncture treatment.
OBJECTIVE:
This systematic survey investigates the magnitude of insert-specific effects of sham acupuncture and whether they affect the estimation of acupuncture treatment effects.
SEARCH STRATEGY:
PubMed, Embase and Cochrane Central Register of Controlled Trials were searched to identify acupuncture RCTs from their inception until December 2022.
INCLUSION CRITERIA:
RCTs that evaluated the effects of acupuncture compared to sham acupuncture and no treatment.
DATA EXTRACTION AND ANALYSIS:
The total effect measured for an acupuncture treatment group in RCTs were divided into three components, including the natural history and/or regression to the mean effect (controlled for no-treatment group), the placebo effect, and the specific effect of acupuncture. The first two constituted the contextual effect of acupuncture, which is mimicked by a sham acupuncture treatment group. The proportion of acupuncture total effect size was considered to be 1. The proportion of natural history and/or regression to the mean effect (PNE) and proportional contextual effect (PCE) of included RCTs were pooled using meta-analyses with a random-effect model. The proportion of acupuncture placebo effect was the difference between PCE and PNE in RCTs with non-inserted sham acupuncture. The proportion of insert-specific effect of sham acupuncture (PIES) was obtained by subtracting the proportion of acupuncture placebo effect and PNE from PCE in RCTs with inserted sham acupuncture. The impact of PIES on the estimation of acupuncture's treatment effect was evaluated by quantifying the percentage of RCTs that the effect of outcome changed from no statistical difference to statistical difference after removing PIES in the included studies, and the impact of PIES was externally validated in other acupuncture RCTs with an inserted sham acupuncture group that were not used to calculate PIES.
RESULTS:
This analysis included 32 studies with 5492 patients. The overall PNE was 0.335 (95% confidence interval [CI], 0.255-0.415) and the PCE of acupuncture was 0.639 (95% CI, 0.567-0.710) of acupuncture's total effect. The proportional contribution of the placebo effect to acupuncture's total effect was 0.191, and the PIES was 0.189. When we modeled the exclusion of the insert-specific effect of sham acupuncture, the acupuncture treatment effect changed from no difference to a significant difference in 45.45% of the included RCTs, and in 40.91% of the external validated RCTs.
CONCLUSION
The insert-specific effect of sham acupuncture in RCTs represents 18.90% of acupuncture's total effect and significantly affects the evaluation of the acupuncture treatment effect. More than 40% of RCTs that used inserted sham acupuncture would draw different conclusions if the PIES had been controlled for. Considering the impact of the insert-specific effect of sham acupuncture, caution should be taken when using inserted sham acupuncture placebos in RCTs.

OBJECTIVE:
To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC).
METHODS:
Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay.
RESULTS:
A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells.
CONCLUSION
C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.
