Stroke ranks as the third leading cause of death and the fourth leading cause of disability worldwide. Its high disability rate and prolonged recovery period not only severely impact patients' quality of life but also impose a significant burden on families and society. Primary prevention is the cornerstone of stroke control, as early intervention on risk factors can effectively reduce its incidence. Therefore, the development of predictive models for first-ever stroke risk holds substantial clinical value. In recent years, advancements in big data and artificial intelligence technologies have opened new avenues for stroke risk prediction. This article reviews the current research status of traditional methods and machine learning models in predicting first-ever stroke risk and outlines future development trends from three perspectives: First, emphasis should be placed on technological innovation by incorporating advanced algorithms such as deep learning and large models to further enhance the accuracy of predictive models. Second, there is a need to diversify data types and optimize model architectures to construct more comprehensive and precise predictive models. Lastly, particular attention should be given to the clinical validation of models in real-world settings. This not only enhances the robustness and generalizability of the models but also promotes physicians' understanding of predictive models, which is crucial for their application and dissemination.

Based on the theory of ti （character， 体） and yong （function， 用） in mental illness， ZHAO Yonghou's clinical experience in staged differentiation and treatment of schizophrenia is summarized. According to the theory， the core disease location of schizophrenia is in the brain， which is closely related to the organs， qi， and blood. It is proposed to interpret the pathogenesis of schizophrenia from the perspective of “zang-fu organs-qi and blood-brain and spirit”， that is， dysfunction of the zang-fu organs， disharmony of qi and blood， and malnourishment of the brain ti lead to dysfunction of the spirit ti and yong. In clinical practice， treatment of schizophrenia can be divided into four stages， for which the method of treating ti and yong simultaneously is suggested. In the prodromal stage， Liuwei Dihuang Decoction combined with Sini San （六味地黄汤合四逆散） with modifications is used to nourish the kidney and boost marrow， soothe the liver and rectify the spleen. For acute exacerbation with binding of phlegm and heat syndrome， Zhaoshi Yikuang Decoction （赵氏抑狂汤） with modifications is used to clear heat and dispel phlegm， awaken the brain and calm the mind. For phlegm-heat damaging yin pattern， Mengshi Guntan Pill combined with Zengye Decoction （礞石滚痰丸合增液汤） with modifications is used to clear heat and dispel phlegm， enrich yin and calm the mind. For the chronic treatment stage， Yudian Decoction （愈癫汤） with modifications is used to disperse phlegm and dissolve stasis， move qi and awaken the mind. For the rehabilitation and regulation stage， Shenan Pill （神安丸） with modifications is used to boost qi and nourish yin， and tranquilize the mind.

OBJECTIVE To establish a clinical pharmaceutical pathway of anti-infective therapy for high-risk populations of antibiotic-associated encephalopathy （AAE）， and analyze its application effects. METHODS Clinical pharmacists developed the “AAE High-Risk Population Screening Form” and “Antibiotic AAE Risk Comparison Form” based on literature and expert opinions， and established the “Clinical Pharmaceutical Pathway of Anti-infective Treatment for AAE High-Risk Population” in our hospital. A prospective， non-randomized controlled study was conducted from May 2023 to April 2024， including 50 cases in the observation group and 50 cases in the control group among patients with pulmonary infections admitted to the Dept. of Internal Medicine in our hospital. The observation group was involved in the development of an anti-infective treatment following the clinical pharmaceutical pathway by clinical pharmacists， while the control group received routine anti-infective treatment by clinical physicians. The occurrence of AAE， the rational antibiotic drug use， and the effectiveness of initial anti-infective treatment in the two groups were observed， and the intervention measures and outcomes of AAE cases were summarized. RESULTS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population was preliminarily established in our hospital. The analysis of the application effects showed that there was 1 case of AAE in the observation group and 8 cases in the control group， with a significantly lower incidence of AAE in the observation group than in the control group； the rational antibiotic drug use and the effectiveness of initial anti-infective treatment in the observation group were both significantly superior to those in the control group （P＜0.05）. Drug withdrawal and dressing change were the preferred effective intervention measures for AAE， and encephalopathy treatment drugs could be used as auxiliary measures for symptom relief. Timely and effective intervention was conducive to rapid symptom relief， with a total improvement rate of AAE of 88.89%. CONCLUSIONS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population can effectively prevent the occurrence of AAE as well as contribute to promoting rational drug use and the effectiveness of initial anti-infection plans and strengthening treatment outcomes.

Schizophrenia has various obstacles in cognition， thinking， emotion， behavior and other aspects； it belongs to the category of “madness” in traditional Chinese medicine （TCM）. Once schizophrenia occurs， multiple factors are often intertwined， and a single therapy is difficult to be effective. At present， TCM compounds and active ingredients have significant effects in the clinical treatment of schizophrenia， which is an important direction for the development of new drugs for schizophrenia. This article summarizes the molecular mechanism of TCM compounds and active ingredients in the treatment of schizophrenia. It is found that Wendan decoction and Yudian decoction can inhibit the apoptosis of hippocampal cells by activating BDNF/TrKB/CREB signaling pathway； quercetin and icariin can promote neural development and regeneration by activating NMDA/ERK signaling pathway； Wendan decoction and icariin can maintain neural cell homeostasis by activating PI3K/AKT signaling pathway； Bushen zhuangyang capsule can enhance learning and memory abilities by activating CaMKⅡ signaling pathway； formulas such as Huatan huoxue tongzhi formula can enhance intercellular information transmission by inhibiting PKC signaling pathway； α-humulene and others can restore nerve cell function by inhibiting NRG1/ErbB4 signaling pathway. TCM compounds and active ingredients can improve schizophrenia by intervening in the above-mentioned signaling pathways.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

As one of the most difficult-to-cure neuropsychiatric disorders in clinical practice， schizophrenia is mainly manifested by behavioral abnormalities and multidimensional cognitive dysfunction， and the recurrence rate and disability rate of the disease are increasing year by year， which seriously affects patients' social functioning and quality of life， and even threatens the physical and mental health of the surrounding population. At present， the treatment of schizophrenia is mainly based on antipsychotic drugs combined with psychotherapeutic techniques， which have limited long-term therapeutic effects and a high relapse rate. Traditional Chinese medicine （TCM） boasts the advantages of multi-targets， multi-pathways， multi-links， and multi-levels， and plays a crucial role in the prevention and treatment of schizophrenia and its prognosis. Phosphatidylinositol 3-kinase （PI3K） is widely present in cells and is involved in the regulation of protein synthesis and apoptosis， and the different isoforms of protein kinase B （Akt） are of great significance in cell growth， oxidative stress， neuronal development and other processes. In recent years， a large number of studies have found that the PI3K/Akt signaling pathway is closely related to schizophrenia. Through regulating the PI3K/Akt signaling pathway， TCM monomers and TCM compounds mainly affect key signaling molecules such as mammalian target of rapamycin （mTOR）， glycogen synthase kinase （GSK）， glucose transporter （GLUT） for glucose uptake and transport， and nuclear factor E₂-associated factor 2 （Nrf2）， which organize the intracellular network of centers and regulate the formation and plasticity of neuronal synapse， and they play an important role in mitigating schizophrenia by regulating the processes of cell proliferation， migration and apoptosis of neurons， and has the advantages of multi-targets， all-encompassing and low toxicity. This article analyzes and explains the mechanism of TCM intervention in the PI3K/Akt signaling pathway against schizophrenia， in order to provide a theoretical basis and reference for the prevention and treatment of schizophrenia by TCM.

Objective To investigate the effect of long non-coding RNA(lncRNA)macrophage migration inhibitory factor antisense RNA1(MIF-AS1)on the malignant biological behavior of prostate cancer(PC)cells by regulating the miR-423-5p/pyrroline-5-carboxylic acid reductase 1(PYCR1)axis.Methods PC3 cells were cultured in vitro to knock down the expression of MIF-AS1 or down-regulate the expression of miR-423-5p.The expression of MIF-AS1,miR-423-5p and PYCR1 mRNA in tumor tissues and adjacent tissues and cells of PC patients were detected.The cell proliferation,apoptosis,migration,and invasion were detected and the expression of PYCR1 protein was detected by Western blot.The relationships between miR-423-5p,IF-AS1 and PYCR1 were verified.Results The MIF-AS1 and PYCR1 mRNA were observed to be highly expressed in the tumor tissues,while miR-423-5p was lowly expressed.Silenced MIF-AS1 inhibited the proliferation,migration and invasion of PC3 cells and up-regulated miR-423-5p induced cell apoptosis(P＜0.05).Inhibition of miR-423-5p expression reversed the inhibitory effect of silencing MIF-AS1 on malignant behavior of PC3 cells(P＜0.05).miR-423-5p was correlated with MIF-AS1 and PYCR1 by targeted regulation.Conclusion Silencing MIF-AS1 may inhibit the expression of PYCR1 by up-regulating miR-423-5p,thereby inhibiting the malignant behavior of PC cells.

Objective:To assess the prevalence of dentinal hypersensitivity (DH) and related factors in urban adults in China.Methods:The study was designed as an observational, cross-sectional epidemiological study carried out in adults aged 18-69 years old in seven cities (Beijing, Shanghai, Wuhan, Chengdu, Xi′an, Guangzhou, and Harbin) of China. The study was conducted from March 2021 to May 2023. Patients were required to complete a questionnaire regarding the subjects′ socio-economic factors, dietary behavior, oral health behavior and personal antecedent factors. DH was clinically diagnosed by judging whether the tooth cold air stimulation provoked DH or not, and recorded by investigator pain rating Schiff score. Compare the findings of six cities (Harbin excluded) with a similar study conducted in 2008.Results:In total, 11 622 subjects from seven cities in China participated the study. Fifty two point two percent (6 072/11 622) of subjects reported DH in questionnaire, 36.7% (4 266/11 622) of subjects reported experiencing DH in response to cold air stimulation for at least one study tooth. Risk factors including age, sex, city, toothbrush method and acid reflux showed marked associations with DH ( P<0.05). The prevalence of DH of urban residents in six cities (Harbin excluded) was 33.7% (3 335/9 882), higher than that in 2008 [29.7%(2 354/7 939)]. Conclusions:Overall, DH was common among urban adults in China and the prevalence increased in recent years. Better understanding of DH and its associated factors should be considered in its prevention and management by dental professionals.

AIM:To investigate the protective effect of total flavonoids from Patrina villosa Juss(PJF)on the lung in an experimental rat model of acute lung injury(ALI),and to elucidate the potential mechanism.METHODS:The ALI rat model was established by instilling 5 mg/kg of lipopolysaccharide(LPS)into the airway.Sixty male SD rats were randomly divided into 4 groups:control,LPS,LPS+low-dose PJF(receiving 100 mg/kg PJF one hour before ALI modeling)and LPS+high-dose PJF(receiving 300 mg/kg PJF one hour before ALI modeling).Each group consisted of 15 animals.Lung tissues and bronchoalveolar lavage fluid(BALF)were collected from all groups 24 h after modeling.For as-sessment of lung tissue morphology,HE staining was performed.The wet/dry weight ratio of the lung tissue was deter-mined using the wet/dry weighing method.Evans blue staining was conducted to assess epithelial barrier permeability in lung tissues.ELISA was used to detect the levels of inflammatory factors tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and IL-6 in the BALF,as well as oxidative stress markers including superoxide dismutase(SOD),myeloperoxi-dase(MPO)and glutathione peroxidase(GSH-Px)activity,and malondialdehyde(MDA)content in the lung tissue.The expression levels of C/EBP homologous protein(CHOP),glucose-regulated protein 78(GRP78)and X-box binding pro-tein 1(XBP1)in the lung tissue were analyzed by Western blotting.RESULTS:Compared with control group,the rats in LPS group exhibited a blurred alveolar structure with a significant infiltration of inflammatory cells.The ALI score and the wet/dry weight ratio of the lung tissue were increased(P<0.05).Concurrently,the levels of IL-6,IL-1β and TNF-α in the BALF,along with MDA content and MPO activity in the lung tissue,were elevated(P<0.05).Additionally,the pro-tein levels of CHOP,GRP78 and XBP1 were up-regulated in the lung tissue(P<0.05),while the SOD and GSH-Px activi-ty was significantly decreased(P<0.05).Compared with LPS group,PJF intervention exerted beneficial effects on the lung tissue morphology with reduced ALI score and lower lung wet/dry weight ratio(P<0.05).Moreover,the levels of IL-6,IL-1β and TNF-α in BALF,as well as MDA content,MPO activity and the protein levels of CHOP,GRP78 and XBP1 in the lung tissue were all significantly decreased(P<0.05),while the SOD and GSH-Px activity was significantly in-creased(P<0.05).The efficacy in high-dose group exceeded that in low-dose group.CONCLUSION:The PJF have pro-tective effect on the lungs of rats with ALI,and its mechanism may be related to the inhibition of inflammation,oxidative stress and endoplasmic reticulum stress.
