Acute Gelsemium poisoning is a systemic disease primarily affecting the central nervous system and respiratory symptoms caused by the ingestion of a substantial amount of Gelsemium within a short period. It manifests as sudden onset and rapid progression, primarily caused by accidental ingestion due to misidentification, and posing significant health risks. The compilation of the Technical Plan for Emergency Health Response to Acute Gelsemium Poisoning describes in detail the specialized practice and technical requirements in the process of handling acute Gelsemium poisoning, including accident investigation and management, laboratory testing and identification, in-hospital treatment, and health monitoring. The guidelines clarify key procedures and requirements such as personal protection, investigation elements, etiology determination, medical rescue, and health education. The key to acute Gelsemium poisoning investigation lies in promptly identifying the toxin through exposure history, clinical manifestations, and sample testing. Because there is no specific antidote for Gelsemium poisoning, immediate removal from exposure, rapid elimination of the toxin, and respiratory monitoring are critical on-site rescue measures. Visual identification of food or herbal materials, followed by laboratory testing to determine Gelsemium alkaloids in samples is a rapid effective screening method. These guidelines offer a scientific, objective, and practical framework to support effective emergency responses to acute Gelsemium poisoning incidences.

Type 2 diabetes mellitus （T2DM） is based on insulin resistance （IR） and insulin secretion deficiency， with the specific mechanisms still unclear. Current research involves mechanisms such as glycolipid toxicity， inflammatory response， oxidative stress damage， and mitochondrial dysfunction. Modern traditional Chinese medicine （TCM） scholars have named it "blood glucose collateral disease" based on the clinical characteristics and natural progression of T2DM. This condition is primarily manifested as abnormal blood sugar levels in the early stages， and as the disease progresses， it gradually causes widespread damage to the body's veins and collaterals， ultimately leading to lesions in vessels and collaterals. Among these， "spleen heat" （obesity type） is the most common clinical type of T2DM. The concept of "internal heat-induced elimination" runs through both the onset and complications of T2DM， with internal heat being a key factor in its pathogenesis. The clinical application of Dahuang Huanglian Xiexintang and its modifications has achieved significant therapeutic effects. This paper reviews the origins and treatment characteristics of Dahuang Huanglian Xiexintang， along with clinical application research and experimental studies related to T2DM treatment， involving mechanisms for regulating glucose and lipid metabolism disorders， improving IR， modulating inflammatory responses， combating oxidative stress damage， regulating autophagy-related signaling pathways， modulating intestinal flora， inhibiting pyroptosis， and alleviating endoplasmic reticulum stress， with the purpose to provide direction for further research on the prevention and treatment of T2DM and its related complications， to offer reference for developing Dahuang Huanglian Xiexintang as a rapid hypoglycemic Chinese patent medicine for obese T2DM， and to better guide the clinical promotion of this drug.

Objective To evaluate the molluscicidal effect and cost of spraying molluscicides with drones against Oncomelania hupensis snails in marshland and lake areas, so as to provide new insights into field snail control in China. Methods A marshland and lake setting measuring approximately 12 000 m² was selected in Wanzhi District, Wuhu City on June 2023 as the test field, and assigned to four groups, of 3 000 m² in each group. Environmental cleaning was not conducted in groups A or B, which were given 5% niclosamide ethanolamine salt granules sprayed with knapsack-type sprayers and drones at a dose of 40 g/m², and environmental cleaning was conducted in groups C and D, which were given 5% niclosamide ethanolamine salt granules sprayed with drones and knapsack-type sprayers at a dose of 40 g/m², respectively. O. hupensis snails were surveyed before chemical treatment and 1, 3, 5, 7, 14 days post-treatment. The uniformity of chemicals was determined on the day of treatment, and the snail mortality, corrected snail mortality and density of living snails were calculated and compared among groups. The cost of molluscicides, labor fees of environmental cleaning and chemical treatment and cost of equipment were calculated, and the cost for a 1% reduction in the mean density of living snails was calculated 14 days post-treatment. Results The mean densities of living snails and mortality rates of snails were 1.82 to 2.85 snails/0.1 m² and 1.41% to 2.94% in groups A, B, C and D before chemical treatment, and the mortality and corrected mortality of snails were 55.75%, 49.32%, 85.94% and 87.50%, and 55.00%, 48.47%, 85.70% and 87.29% in groups A, B, C and D 14 days post-treatment. There was a significant difference in the mortality of snails among the four groups 14 days post-treatment (χ² = 38.735, P < 0.005), and there was a higher snail mortality in Group D than in Group A (χ² = 16.876, P < 0.005), and higher in Group C than in Group B (χ² = 20.508, P < 0.005). The density of living snails reduced by 55.00%, 43.94%, 90.43% and 87.14% 14 days post-treatment relative to pre-treatment in groups A, B, C and D, respectively. The test for uniformity of chemicals showed that the mean dose of molluscicides were 57.34, 55.21, 40.19 g/m² and 32.37 g/m² in groups A, B, C and D, respectively, and the minimal standard deviation (7.07) and coefficient of variation (0.18) of mean doses were seen in Group C. The costs for chemical treatment were 0.33 Yuan in groups A and B and 1.53 Yuan in groups C and D, respectively. The costs for a 1% reduction in the mean density of living snails were 17.82, 22.47, 50.73 Yuan and 52.56 Yuan in groups A, B, C, and D 14 days post-treatment, respectively. Conclusions The molluscicidal effect and cost of spraying 5% niclosamide ethanolamine salt granules with drones are comparable to manual spraying, and chemical treatment with drones are high in uniformity of molluscicides, time- and labor-saving, and feasible for applications in complex environments, which deserves widespread applications in the field of snail control.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM:To investigate the effect of ankyrin repeat domain 49(ANKRD49)on epithelial-mesenchy-mal transition(EMT)in NCI-H1299 cells,and to explore its mechanism.METHODS:The ANKRD49 was over-ex-pressed in NCI-H1299 cells.The morphological changes of ANKRD49-overpressing NCI-H1299 cells were observed under microscope.The mRNA and protein expression levels of EMT-related markers[E-cadherin,transforming growth factor-β1(TGF-β1),vimentin and α-smooth muscle actin(α-SMA)]and EMT-related transcription factors(Snail1,Slug,Twist and ZEB1)were detected by RT-qPCR Western blot.Immunofluorescence staining was performed to observe the localiza-tion and expression of E-cadherin and vimentin in ANKRD49-overexpressing cells or control cells.Immunohistochemical method was performed to examine the levels of E-cadherin,α-SMA,Snail,Slug and ZEB1 in lung tissues of nude mice in-oculated with ANKRD49-overexpressing H1299 cells or control cells.RESULTS:Compared with the control group,the ANKRD49 overexpressing cells showed mesenchymal cell morphology(fusiform and less tight connections).RT-qPCR and Western blot results showed that the mRNA and protein levels of mesenchymal markers vimentin and α-SMA in ANKRD49 overexpressing cells were significantly higher than those in cells of control group,while the mRNA and protein levels of epithelial marker E-cadherin were lower than those in cells of control group.Compared with control group,the im-munofluorescence intensity of E-cadherin of H1299 cells decreased in after ANKRD49 overexpression,while that of vimen-tin increased significantly.Snail,Slug and ZEB1 expression were significantly elevated in ANKRD49 overexpressing cells compared with control group.The levels of E-cadherin in lung tissues of nude mice inoculated with ANKRD49-overexpressing H1299 cells declined,while the levels of α-SMA,Snail,Slug and ZEB1 increased compared with those in control mice.CONCLUSION:ANKRD49 promoted EMT of NCI-H1299 cells by increasing the expression of Snail1,Slug and ZEB1 and consequent downreguation of E-cadherin and upregulation of vimentin and α-SMA.

Osteoarthritis (OA) is one of the most common chronic diseases in the world. However, current treatment modalities mainly relieve pain and inhibit cartilage degradation, but do not promote cartilage regeneration. In this study, we show that G protein-coupled receptor class C group 5 member B (GPRC5B), an orphan G-protein-couple receptor, not only inhibits cartilage degradation, but also increases cartilage regeneration and thereby is protective against OA. We observed that Gprc5b deficient chondrocytes had an upregulation of cartilage catabolic gene expression, along with downregulation of anabolic genes in vitro. Furthermore, mice deficient in Gprc5b displayed a more severe OA phenotype in the destabilization of the medial meniscus (DMM) induced OA mouse model, with upregulation of cartilage catabolic factors and downregulation of anabolic factors, consistent with our in vitro findings. Overexpression of Gprc5b by lentiviral vectors alleviated the cartilage degeneration in DMM-induced OA mouse model by inhibiting cartilage degradation and promoting regeneration. We also assessed the molecular mechanisms downstream of Gprc5b that may mediate these observed effects and identify the role of protein kinase B (AKT)-mammalian target of rapamycin (mTOR)-autophagy signaling pathway. Thus, we demonstrate an integral role of GPRC5B in OA pathogenesis, and activation of GPRC5B has the potential in preventing the progression of OA.

Objective: To analyze the trends of incidence and age change for global female breast cancer in different regions of the world according to the database from Cancer Incidence in Five Continents Time Trends (CI5plus) published by the International Association of Cancer Registries (IACR). Methods: The recorded annual female breast cancer (ICD-10: C50) incidence data and corresponding population at-risk data (1998-2012) were extracted from CI5plus published by IACR. The annual change percentage and average annual change percentage (AAPC) were calculated to examine the trends of incidence. The age-standardized mean age at diagnosis and proportion of incidence cases by age were calculated to analyze the relationship between incidence and age. Results: For crude incidence, except in Northern America, all other regions showed an upward trend, with Asia showing the most obvious upward trend (AAPC: 4.1%, 95% CI: 3.9%, 4.3%). For age-standardized incidence, in Asia, Latin America and Europe, the rising trends had slowed down, in Oceania and Africa, the trends began to be stable, and in Northern America, the trend showed a downward trend (APPC: -0.6%; 95% CI: -1.0%, -0.1%). The mean age at diagnosis were increased from 1998 to 2012 in Asia, Latin America, Oceania and Europe, with an annual increase of 0.12 years, 0.09 years, 0.04 years and 0.03 years, respectively. But after age-standardized, only Europe still kept increasing year by year, with an annual increase of 0.02 years, while Northern America showed a decreasing trend, with an annual decrease of about 0.03 years. Conclusions: From 1998 to 2012, the trends of incidence and age change for global female breast cancer vary in different regions of the world, and the global population aging is widespread, which affects the trend of the actual age change. Prevention and control strategies should be targeted at different age groups in different regions.

ObjectiveTo discuss the effect of modified Gegen Qinliantang （MGQT） on blood glucose and lipids and Takeda G protein-coupled receptor 5 （TGR5）-related pathways in pancreatic tissue of obese type 2 diabetes mellitus （T2DM） mice. MethodA total of 10 male specific pathogen free （SPF） m/m mice （7 weeks old） and 50 male SPF （7 weeks old） were adaptively fed for one week in SPF laboratory. The m/m mice were included in the blank group. T2DM was induce d in the 50 db/db mice. The model mice were randomized into the model group， metformin group （0.2 g·kg^-1）， high-dose， medium-dose， and low-dose （31.9， 19.1， 6.4 g·kg^-1） MGQT groups， with 10 in each group， and the drug dose was10 mL·kg^-1. The model group and the blank group received distilled water of the same volume. The administration lasted 12 weeks （once/day）. Fasting blood glucose （FBG） was detected regularly. After 12 weeks of administration， serum levels of glycated serum protein （GSP）， serum glucose （GLU）， total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） were detected. Pathological changes in the pancreatic tissue were based on hematoxylin-eosin （HE） staining. Western blot was used to determine the protein expression of TGR5， protein kinase A （PKA）， phosphorylated （p）-PKA， cyclic-AMP response element binding protein （CREB）， p-CREB， proprotein convertase 1/3 （PC1/3）， and glucagon-like peptide-1 （GLP-1） in pancreatic tissues. The level of cyclic adenosine monophosphate （cAMP） in pancreatic tissue was determined by enzyme-linked immunosorbent assay （ELISA）. ResultCompared with the blank group， the model group had pathological changes in pancreatic tissue， high levels of FBG， GSP， GLU， TC， TG， and LDL-C （P<0.01）， low level of HDL-C （P<0.05）， low protein expression of TGR5， p-PKA （Thr197）/PKA， p-CREB （Ser133）/CREB， PC1/3， and GLP-1 in pancreatic tissue （P<0.01）， and low content of cAMP in the pancreas （P<0.01）. Pancreatic tissue lesion in the treatment groups were milder than that in the model group. Both the high-dose MGQT and metformin can reduce the levels of FBG， GSP， GLU， TC， TG， and LDL-C in db/db mice （P<0.05， P<0.01） and increase the level of HDL-C （P<0.01）. Except the GLP-1 protein in the medium-dose MGQT group， the protein expression of TGR5， p-PKA （Thr197）/PKA， p-CREB （Ser133）/CREB， PC1/3， and GLP-1 in the high-dose and medium-dose MGQT groups and the metformin group increased compared with that in the model group （P<0.05， P<0.01）. The content of cAMP in the pancreatic tissue of the high-dose and medium-dose MGQT groups and the metformin group was raised compared with that in model group （P<0.05， P<0.01）. ConclusionMGQT can improve the glucose homeostasis in db/db mice with T2DM by regulating TGR5/cAMP/GLP-1 signaling pathway-related protein expression.
