Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Stroke is the main cause of death and disability among adults in China and is characterized by high incidence， disability， mortality， and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang （DCQT） has a long history and proven efficacy in treating stroke. Clinically， DCQT is often used to treat stroke and its sequelae. However， the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research， the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage， reduce iron deposition， and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 （Nrf2）-mediated signaling pathway and p38 mitogen-activated protein kinase （MAPK） signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT， this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials， pharmacodynamic material basis， safety evaluation， and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT， 11 of which are currently confirmed absorbed components. Among them， emodin， rhein， chrysophanol， aloe-emodin， synephrine， hesperidin， naringin， magnolol， and honokiol can be used as quality markers （Q-markers） of DCQT. The mechanism of DCQT in treating stroke is complex， involving regulation of inflammatory responses， neuronal damage， oxidative stress， blood-brain barrier， brain-derived neurotrophic factor， and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

Objective:It analyzes the flow characteristics and spatial distribution patterns of intra-provincial cross-regional medical patients in Guangdong,while comparing hospitalization cost differences between local and non-local care.Methods:Based on 2022-2023 cross-regional medical data from Guangdong,spatial visualization and descriptive analysis were conducted combined with Mann-Whitney U test to compare the cost burden.Results:Cross-Regional patients in Guangdong primarily flow to Guangzhou,accounting for 77.8％of the total intra-provincial cross-regional hospitalizations.Cross-regional medical expenses were significantly higher than the insured locations,with notable differences in mean total hospitalization costs and personal out-of-pocket payment ratios.Conclusion:Refining pre-approval procedures for cross-regional care,enhancing specialized medical departments in under-resourced regions,and strengthening coordination between healthcare insurance systems and primary healthcare strengthening initiatives are needed to promote balanced medical resource allocation and reduce the cost burden on patients.

Objective To evaluate the efficiency of health resource allocation in 22 types of hospital institutions in Guangdong Province from 2018 to 2022,identify their strengths and shortcomings in resource utilization,and offer evidence-based recommendations for optimizing medical resource allocation and policymaking.Methods The efficiency of health resource allocation was assessed using the DEA-BCC model and the DEA-Malmquist index model across the 22 hospital categories.Results In 2022,the overall resource allocation efficiency of the 22 types of hospital institutions in Guangdong Province was suboptimal,with an average score of 0.657.From 2018 to 2022,the mean total factor productivity(TFP)change index for these hospitals was 0.968,with only 6 categories exhibiting a TFP index exceeding 1.Conclusion The efficiency of health resource allocation in Guangdong's hospitals remains inadequate.Government authorities should enhance macro-level planning for regional resource distribution,accelerate advancements in medical technology,and establish a real-time monitoring framework.Concurrently,policy interventions and incentive mechanisms should be reinforced to ensure both scientifically sound allocation and effective utilization of medical resources.

AIM:To investigate the antiviral effica-cy and mechanism of Qingre Xiaoyanning(QRXYN)in vivo,and provide experimental basis for their prevention and treatment of influenza A virus.METHODS:We constructed a mouse model infect-ed with influenza A H3N2 virus.To evaluate the therapeutic effect of QRXYN on influenza A virus,we measured the body weight changes,pathologi-cal changes in lung tissue,hemagglutination titer,and viral load in mouse.To evaluate the possible mechanism of QRXYN's anti influenza A virus infec-tion,we used the ELISA to measure the levels of TNF-α,IL-1β,IL-4,IFN-γ,and vascular cell adhesion molecule-1(VCAM-1)in mouse bronchoalveolar Ia-vage fluid;used flow cytometry to assess the pro-portions of macrophages(F4/80),helper T lympho-cytes(CD4+T lymphocytes),and natural killer(NK)cells in lung tissue;and used Western blotting to detect the expression of Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MYD88),inhibitor of kappa B kinase-β(IKK-β),NF-kappa-B inhibitor al-pha(IκBα),and phospho-IKB alpha(p-IκBα)in lung tissue.RESULTS:Compared to the model group,both Oseltamivir and QRXYN can alleviate the se-verity of lung tissue lesions in mice,decrease the blood coagulation titer and viral load of mouse lung tissue(P＜0.01),lower the levels of TNF-α,IL-4,and VCAM-1 in bronchoalveolar lavage fluid(P＜0.05,P＜0.01),reduce the proportion of macro-phages(P＜0.05,P＜0.01),and increase the propor-tion of CD4+T lymphocytes and NK cells(P＜0.05,P＜0.01).Additionally,oseltamivir can reduce the ex-pression of MYD88 protein in mouse lungs(P＜0.05),while QRXYN can decrease the expression of IKK-β and P-IκBα proteins in mouse lungs(P＜0.05).CONCLUSION:QRXYN have good in vivo antiviral ef-fects against the influenza A virus,and their mecha-nism may be related to the regulation of the immu-nologic function and NF-κB signal pathway.

Objective:To investigate the clinical effect of splenic blood flow blockade in Kimura laparoscopic splenic body and pancreatic caudectomy.Methods:A retrospective case-control study was used to analyze the clinical data of 48 patients undergoing Kimura laparoscopic splenopancreato-caudectomy in Huangshi Central Hospital from January 2018 to December 2023. According to whether the splenic arteriovenous occlusion was performed during the operation, 25 cases were divided into a blocking group and 23 cases were not blocked. The operative time, intraoperative blood loss, intraoperative blood transfusion cases, postoperative drainage tube placement time, postoperative hospitalization days and postoperative complication rate were compared between the two groups. Measurement data with normal distribution were represented by mean±standard deviation ( ± s), independent sample t-test was used for inter-group comparison, and chi-square test was used for inter-group comparison. Results:The operation was successfully performed in both groups without perioperative death. In the blocking group, the operation time, intraoperative blood loss and postoperative hospitalization time were (166.4±28.3) min, (390.5±88.9) mL and (6.5±1.6) d, respectively. The results were significantly better than those in the unblocked group (191.5±29.7) min, (552.2±108.3) mL and (8.3±2.8) d( P<0.05). There were no intraoperative transfusion cases in the blocking group and 4 cases in the non-blocking group, and the difference between the two groups was statistically significant ( P<0.05). There were 2 cases of partial infarct in the blocking group and 1 case in the unblocking group, and there was no significant difference between the two groups ( P>0.05). There were 4 cases in the non-blocking group, and no cases in the blocking group. The splenectomy rate in the blocking group was significantly lower than that in the non-blocking group ( P<0.05). There was no significant difference in the incidence of other postoperative complications (thrombocytosis, portal vein thrombosis, B/C grade pancreatic leakage and perigastric varicose veins) in the blocking group compared with the non-blocking group ( P>0.05). Conclusions:Splenic blood flow blockade Kimura method is safe and effective. Intraoperative splenic arteriovenous blockade has more advantages in controlling intraoperative bleeding and successfully preserving spleen, which can accelerate the recovery of patients and is more in line with the concept of ERAS.

BACKGROUND:A large number of studies have confirmed that tissue engineering scaffolds can almost completely repair osteochondral defects.However,when osteochondral defects are complicated with infection,even after thorough debridement in the early stage,the repair effect of simple osteochondral tissue engineering scaffolds is often unsatisfactory. OBJECTIVE:To prepare fibroin/chitosan/nano-hydroxyapatite scaffold loaded with vancomycin hydrochloride sustained release microspheres,and to investigate the repair effect on infected osteochondral defect in distal femur of rabbit. METHODS:(1)Vancomycin hydrochloride sustained release microspheres were prepared by emulsified solvent evaporation method.The sustained-release microspheres of different weights(7.5,10,and 12.5 mg)were mixed with fibroin protein-chitosan nanohydroxyapatite solution,and the scaffolds of fibroin protein/chitosan/nano-hydroxyapatite were prepared by chemical crosslinking method.The porosity,water absorption and expansion rate,hot water loss rate of the scaffolds,and drug sustained-release in vitro were characterized.(2)Forty-five New Zealand white rabbits were randomly divided into blank group,control group,and experimental group,with 15 rabbits in each group.The osteochondral defect and infection model of the distal femur of the right hind limb was established in both groups.The blank group was not treated,and the control group was implanted with fibroin protein-chitosan-nano-hydroxyapatite scaffold.Vancomycin hydrochloride sustained-release microspheres(10 mg)of fibroin/chitosan/nano-hydroxyapatite scaffold were implanted in the defect of the experimental group.The levels of C-reactive protein and leukocytes in blood samples were detected 1 week after operation.At 4,8 and 12 weeks after operation,the tissue of the operative area was taken for gross observation and pathological observation. RESULTS AND CONCLUSION:(1)With the increase of sustained-release microspheres content,the porosity of scaffolds decreased,and there was significant difference among groups(P＜0.05).There were no significant differences in the pore size,water absorption expansion rate and hot water loss rate among the three groups(P＞0.05).Vancomycin hydrochloride was released sustainably in vitro for more than 30 days in all three groups of scaffolds.(2)The levels of C-reactive protein and leukocytes in blood samples of the experimental group were lower than those of the blank group and control group(P＜0.05).The repair of gross cartilage in the experimental group was significantly better than that in the blank group and the control group.Hematoxylin-eosin,Masson,Alcian blue and type Ⅱ collagen immunohistochemical stainings showed that the osteochondral repair effect of the experimental group was significantly better than that of the blank group and the control group at each time point.(3)The results showed that fibroin/chitosan/nano-hydroxyapatite scaffolds loaded with vancomycin hydrochloride sustained-release microspheres could effectively promote the repair of open osteochondral defects.
