Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

AIM:To observe the clinical efficacy of intravitreal injection of conbercept in the treatment of macular edema secondary to non-ischemic retinal vein occlusion(RVO).METHODS: Single center retrospective study. ME patients secondary to non-ischemic RVO admitted to the hospital from January 2023 to March 2024 were selected, and were divided into central retinal vein occlusion(CRVO)group and branch retinal vein occlusion(BRVO)group according to the location of obstruction. All patients were treated with intravitreal injection of conbercept once a month for 3 mo. The best corrected visual acuity(BCVA), macular foveal thickness(CMT), superficial capillary density(SVD), deep capillary density(DVD), and foveal avascular zone(FAZ)area were recorded before and after treatment(with 3 injections per course)at 1, 3, and 6 mo.RESULTS:This study included a total of 120 ME secondary to non-ischemic RVO patients(128 eyes), who were divided into CRVO group(51 cases, 56 eyes, 31 males, 20 females, mean age 61.39±10.32 y)and BRVO group(69 cases, 72 eyes, 41 males, 28 females, mean age 61.48±10.41 y)based on the location of obstruction. There was no significant difference in general data between the two groups before treatment(both P>0.05). After 1, 3, and 6 mo of treatment, both groups showed improvement in BCVA, CMT, SVD, and DVD compared to before treatment(all P<0.05). BCVA in the BRVO group was better than that in the CRVO group at all time points after treatment(all P<0.05), while there was no difference in CMT, SVD, and DVD between the two groups(all P>0.05); There was no significant difference in FAZ area between the two groups before and after treatment(both P>0.05). Follow up for 6 mo showed no significant difference in the incidence of complications between the two groups of patients(both P>0.05), but there was a significant difference in the recurrence rate(P<0.05).CONCLUSION: The first intravitreal injection of conbercept is effective in treating macular edema caused by non-ischemic CRVO and BRVO, improving visual function, reducing macular edema, and repairing retinal structure and blood flow perfusion. Notably, the recovery of visual function and improvement of capillary density are more significant in BRVO patients.

Objective: To explore the types and levels of exosomes in cryoprecipitate from donors of different blood types, genders, and age groups, and to preliminarily characterize their specific proteins. Methods: Exosomes were extracted from cryoprecipitate using the polymer precipitation method. The exosomes were identified by particle size analysis, transmission electron microscopy, and Western blot. Finally, the specific proteins CD63, CD81, CD9, Cytochrome C, Syntenin-1, and VLA-4 of exosomes were characterized using Luminex. Results: The purified exosomes exhibited a double-membrane vesicle structure under microscopy, appearing saucer-shaped or as hemispheres with a concave side. They specifically expressed the CD63 and TSG101 proteins, while the endoplasmic reticulum protein Calnexin was not expressed. The particle sizes(nm) of exosomes from blood types A, B, O, and AB were 119.6±47.5, 120.5±47.4, 133.3±54.1 and 103.1±35.3, respectively. Taking the exosomal specific protein CD63 as an example, its expression levels(pg/mL) in cryoprecipitate from female and male donors were 128.22±63.52 and 117.39±40.84, respectively; the expression(pg/mL) levels in the 20-40 and 40-60 age groups were 114.20±37.28 and 131.41±64.98, respectively; and the expression levels(pg/mL) in the four blood types A, B, O, and AB were 109.58±37.79, 127.45±44.46, 131.89±40.59, and 122.29±78.68, respectively. The expression levels of CD63 in exosomes from different blood types, genders, and age groups were similar, with no statistically significant differences (all P>0.05). The distribution of the other five exosomal-specific proteins was also comparable among the normal blood donors. Conclusion: The expression levels of exosomal-specific proteins in cryoprecipitate from normal blood donors are not associated with blood type, gender, and age group.

ObjectiveCandidate genes related to the regulation of litter size traits in English Springer Spaniel breeding bitches are explored, and the genetic mechanism underlying fertility in this breed is investigated, in order to provide reference molecular markers for genomic selection of high fecundity. MethodsWhole genome resequencing was performed on English Springer Spaniel breeding bitches that had given birth to at least 3 litters, and the bitches were divided into a high-litter-size group and a low-litter-size group according to the average litter size. Selection signal analysis was used to obtain the intersection of fixation index (Fst) and nucleotide diversity (Pi) signals as highly selected regions, and candidate genes were screened based on gene annotation and functional enrichment analysis. ResultsThe average litter size in the high-litter-size group (7.41±1.27) was significantly higher than that in the low-litter-size group (3.82±1.20) (P<0.05), and the total number of live offspring in the high-litter-size group (7.06±1.10) was extremely significantly higher than that in the low-litter-size group (3.67±1.11) (P<0.01). A total of 3 155 706 SNPs were detected in the two groups, 63.09% of which were located in intergenic regions, 33.96% in intronic regions, and 0.38%, 0.57%, and 0.09% in exonic regions, 3' untranslated regions (UTRs), and 5'UTRs, respectively. Among the SNPs in exonic regions, 5 256 were nonsynonymous variants, accounting for 43.55%. A total of 1 752 differential genes were identified after annotation screening. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses identified 13 candidate genes that may affect reproductive performance and litter size traits, including WDR35, SMAD7, RPGR, RERGL, PGRMC2, LOC482182, GIMD1, COX7B2, COX16, BMPR2, BMP6, BICD1, and SLC9C1. Their functions mainly involve reproductive hormone regulation, embryonic development, GTPase activation, and oocyte apoptosis. ConclusionEnglish Springer Spaniel breeding bitches have undergone significant artificial selection for litter size traits. These 13 candidate genes play key roles in oocyte maturation and regulation during early pregnancy, providing a new molecular basis for elucidating the genetic mechanism of canine reproductive traits.

Objective To investigate the suitable habitats of Phlebotomus chinensis in Gansu Province, so as provide insights into effective management of mountain-type zoonotic visceral leishmaniasis (MT-ZVL). Methods The geographical coordinates of locations where MT-ZVL cases were reported were retrieved in Gansu Province from 2015 to 2023, and data pertaining to 26 environmental variables were captured, including 19 climatic variables (annual mean temperature, mean diurnal range, isothermality, temperature seasonality, maximum temperature of the warmest month, minimum temperature of the coldest month, temperature annual range, mean temperature of the wettest quarter, mean temperature of the driest quarter, mean temperature of the warmest quarter, mean temperature of the coldest quarter, annual precipitation, precipitation of the wettest month, precipitation of the driest month, precipitation seasonality, precipitation of the wettest quarter, precipitation of the driest quarter, precipitation of the warmest quarter, and precipitation of the coldest quarter), five geographical variables (elevation, annual normalized difference vegetation index, vegetation type, landform type and land use type), and two population and economic variables (population distribution and gross domestic product). Twelve species distribution models were built using the biomod2 package in R project, including surface range envelope (SRE) model, generalized linear model (GLM), generalized additive model (GAM), multivariate adaptive regression splines (MARS) model, generalized boosted model (GBM), classification tree analysis (CTA) model, flexible discriminant analysis (FDA) model, maximum entropy (MaxEnt) model, optimized maximum entropy (MAXNET) model, artificial neural network (ANN) model, random forest (RF) model, and extreme gradient boosting (XGBOOST) model. The performance of 12 models was evaluated using the area under the receiver operating characteristic curve (AUC), true skill statistics (TSS), and Kappa coefficient, and single models with high performance was selected to build the optimal ensemble models. Factors affecting the survival of Ph. chinensis were identified based on climatic, geographical, population and economic variables. In addition, the suitable distribution areas of Ph. chinensis were predicted in Gansu Province under shared socioeconomic pathway 126 (SSP126), SSP370 and SSP585 scenarios based on climatic data during the period from 1991 to 2020, from 2041 to 2060 (2050s), and from 2081 to 2100 (2090s) . Results A total of 11 species distribution models were successfully built for prediction of potential distribution areas of Ph. chinensis in Gansu Province, and the RF model had the highest predictive accuracy (AUC = 0.998). The ensemble model built based on the RF model, XGBOOST model, GLM, and MARS model had an increased predictive accuracy (AUC = 0.999) relative to single models. Among the 26 environmental factors, precipitation of the wettest quarter (12.00%), maximum temperature of the warmest month (11.58%), and annual normalized difference vegetation index (11.29%) had the greatest contributions to suitable habitats distribution of Ph. sinensis. Under the climatic conditions from 1991 to 2020, the potential suitable habitat area for Ph. chinensis in Gansu Province was approximately 5.80 × 104 km2, of which the highly suitable area was 1.42 × 104 km2, and primarily concentrated in the southernmost region of Gansu Province. By the 2050s, the unsuitable and lowly suitable areas for Ph. chinensis in Gansu Province had decreased by varying degrees compared to that of 1991 to 2020 period, while the moderately and highly suitable areas exhibited expansion and migration. By the 2090s, under the SSP126 scenario, the suitable habitat area for Ph. chinensis increased significantly, and under the SSP585 scenario, the highly suitable areas transformed into extremely suitable areas, also showing substantial growth. Future global warming is conducive to the survival and reproduction of Ph. chinensis. From the 2050s to the 2090s, the highly suitable areas for Ph. chinensis in Gansu Province will be projected to expand northward. Under the SSP126 scenario, the suitable habitat area for Ph. chinensis in Gansu Province is expected to increase by 194.75% and 204.79% in the 2050s and 2090s, respectively, compared to that of the 1991 to 2020 period. Under the SSP370 scenario, the moderately and highly suitable areas will be projected to increase by 164.40% and 209.03% in the 2050s and 2090s, respectively, while under the SSP585 scenario, they are expected to increase by 195.98% and 211.66%, respectively. Conclusions The distribution of potential suitable habitats of Ph. sinensis gradually shifts with climatic changes. Intensified surveillance and management of Ph. sinensis is recommended in central and eastern parts of Gansu Province to support early warning of MT-ZVL.

Objective: To establish a "regular blood donor red blood cell gene database"(hereafter referred to as the "database") by applying molecular biology techniques for red blood cell antigens genotyping and utilizing information technology software, and to determine the significance and application value of this "database" in precise red blood cell transfusion. Methods: Fifteen antigens [C, c, E, e, M, N, S, s, Fy (a), Fy (b), Jk (a), Jk (b), Le (a), Le (b), P1] across six blood group systems (RHCE, MNS, FY, JK, Lewis and P1PK) were detected among 9 426 regular blood donors using the TaqMan-MGB method combined with an improved U-shaped microplate approach. With the assistance of information technology software, the "database" was integrated into the overall inventory management system of the blood supply chain. This enabled comprehensive management of regular blood donor and patient information, test results, specific antigen screening for regular blood donors, graded antigen matching between donors and patients, and rare blood type donor records. Results: The TaqMan-MGB method successfully detected paired antigens (C/c, E/e, M/N, S/s, Fy
/Fy
, Jk
/Jk
) within a single reaction well using a standardized PCR amplification protocol. This method provided a reliable testing solution for clinical institutions and empowered blood collection and supply organizations with high-throughput screening capabilities. In the blood supply chain, genotyped red blood cells accounted for 13.2% (721/5 462 U) of the total inventory, with 95.34% (348/365) originating from donors who donated two units of blood. Moreover, the “database” fulfilled 94.06% (443/471 U) of compatible transfusion requirements from medical institutions and effectively managed rare blood type donors. Conclusion: The establishment of the "database" facilitated the transition of blood compatibility testing from traditional serological methods to molecular biology-based gold standard techniques, significantly advancing the implementation of precise transfusion strategies based on multi-antigen matching between donors and patients.

Based on the theory of the five-body constituents from Huangdi Neijing (Yellow Emperor's Internal Classic), the approach and methods of acupuncture for facial aging are explored. Acupuncture for facial aging can be guided by the concept of the five-body constituents, targeting the facial "skin, flesh, vessels, tendons, and bones", and utilizing five different types of needles-facial needles, needle knives, filiform needles, retaining needles, and elongated needles and filiform needles-to maximize their respective advantages in treating facial aging. Facial needles are applied to the "skin" by selecting facial acupoints or local ashi points (at wrinkle or pigmentation sites). Needle knives are used for the "flesh" to perform longitudinal dredging and transverse dissection of the facial muscle layers. Filiform needles target the "vessels" with needling at Renying (ST9) to improve facial complexion. Retaining needles act on the "tendons" with needling from Taiyang (EX-HN5) to Xiaguan (ST7), and Jiache (ST6) to Daying (ST5), using clockwise twisting to generate a retaining needle sensation and lifting to achieve an overall facial lifting effect.

Chinese Medical Journal 2025;138(22):2993-3003
BACKGROUND:
Arsenic trioxide (ATO) is indicated as a broad-spectrum medicine for a variety of diseases, including cancer and cardiac disease. While the role of ATO in hepatic ischemia/reperfusion injury (HIRI) has not been reported. Thus, the purpose of this study was to identify the effects of ATO on HIRI.
METHODS:
In the present study, we established a 70% hepatic warm I/R injury and partial hepatectomy (30% resection) animal models in vivo and hepatocytes anoxia/reoxygenation (A/R) models in vitro with ATO pretreatment and further assessed liver function by histopathologic changes, enzyme-linked immunosorbent assay, cell counting kit-8, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Small interfering RNA (siRNA) for extracellular signal-regulated kinase (ERK) 1/2 was transfected to evaluate the role of ERK1/2 pathway during HIRI, followed by ATO pretreatment. The dynamic process of autophagic flux and numbers of autophagosomes were detected by green fluorescent protein-monomeric red fluorescent protein-LC3 (GFP-mRFP-LC3) staining and transmission electron microscopy.
RESULTS:
A low dose of ATO (0.75 μmol/L in vitro and 1 mg/kg in vivo ) significantly reduced tissue necrosis, inflammatory infiltration, and hepatocyte apoptosis during the process of hepatic I/R. Meanwhile, ATO obviously promoted the ability of cell proliferation and liver regeneration. Mechanistically, in vitro studies have shown that nontoxic concentrations of ATO can activate both ERK and phosphoinositide 3-kinase-serine/threonine kinase (PI3K-AKT) pathways and further induce autophagy. The hepatoprotective mechanism of ATO, at least in part, relies on the effects of ATO on the activation of autophagy, which is ERK-dependent.
CONCLUSION
Low, non-toxic doses of ATO can activate ERK/PI3K-AKT pathways and induce ERK-dependent autophagy in hepatocytes, protecting liver against I/R injury and accelerating hepatocyte regeneration after partial hepatectomy.
