ObjectiveThis paper aims to verify the therapeutic effect of Cranial Painkiller pills' extract powder prepared by the new process on the rat's trigeminal neuralgia model caused by infraorbital injection of Talci Pulvis， evaluate its potential clinical application value， and compare the therapeutic effect with that of Cranial Painkiller granules， so as to provide data support for the application of the Cranial Painkiller pills' extract powder and precise treatment. MethodsThe rat's trigeminal neuralgia model was constructed by infraorbital injection of Talci Pulvis， and the rats were randomly divided into the normal group， model group， carbamazepine group （60 mg·kg^-1）， Cranial Painkiller granules group （2.70 g·kg^-1）， and low， medium， and high dosage groups of Cranial Painkiller pills' extract powder （1.35， 2.70， 5.40 g·kg^-1） according to the basal mechanical pain thresholds， and there were 10 rats in each group. The drug was administered by gavage to each group 2 h after modeling， and distilled water was given by gavage to the normal and model groups under the same conditions once a day for 10 d. Von Frey brushes were used to measure mechanical pain thresholds in rats. Hematoxylin-eosin （HE） staining was used to detect pathological changes in the trigeminal ganglion， and enzyme-linked immunosorbent assay （ELISA） was used to detect the inflammatory factors interleukin-1 （IL-1）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， and tumor necrosis factor-α （TNF-α） levels in rat serum， as well as neuropeptide substance P （SP） and β-endorphin （β-EP） levels in rat brain tissue. Western blot technique was used to detect the levels of NLRP3， ASC， Caspase-1， and OTULIN proteins in rat brain tissue. ResultsCompared with the normal group， the pain threshold of rats in the model group showed a continuous significant decrease （P<0.01）. The pathological damage of brain tissue was significant （P<0.01）， and the inflammatory levels of IL-1， IL-6， IL-8， and TNF-α in serum were significantly elevated （P<0.01）. The level of the SP in the brain tissue was significantly elevated （P<0.01）， and the level of β-EP was significantly reduced （P<0.01）， while the level of OTULIN was significantly reduced， and NLRP3， ASC， and Caspase-1 protein levels were significantly elevated （P<0.01）. After administration of the drug， compared with the model group， the pain threshold of each dose group of the Cranial Painkiller pills' extract powder and the Cranial Painkiller granules group significantly increased （P<0.01）. The inflammatory levels of IL-1， IL-6， IL-8， and TNF-α and SP levels significantly decreased （P<0.01）， and the β-EP levels were significantly elevated （P<0.01）， while the levels of OTULIN protein were significantly elevated （P<0.05， P<0.01）， and the levels of NLRP3， ASC proteins were decreased （P<0.01）in high dose Cranial Painkiller pills' extract powder. Meanwhile， compared with those in the model group， the trigeminal ganglion lesions of rats in the Cranial Painkiller pills' extract powder and Cranial Painkiller granules groups showed different degrees of improvement （P<0.05， P<0.01）. ConclusionThe Cranial Painkiller pills' extract powder has significant therapeutic effects on the rat model of trigeminal neuralgia induced by infraorbital injection of Talci Pulvis， and its mechanism is related to the improvement of OTULIN-regulated neuroinflammation.

ObjectiveTo evaluate the effect of antihypertensive and lipid-regulating Chinese patent medicine combined with conventional Western medicine in the treatment of hypertension with dyslipidemia. To carry out the evidence synthesis of clinical research and provide evidence-based evidence support for clinical decision-making. MethodThe databases including China National Knowledge Infrastructure （CNKI），Wanfang Data Knowledge Service Platform （WF），VIP，SinoMed，Embase，PubMed，Web of Science （WOS），and the Cochrane Library were searched for randomized controlled trials （RCT） of all listed Chinese patent medicines in the treatment of hypertension with dyslipidemia from the establishment of the databases to April 15，2023. The literature was screened and extracted，and the risk of bias tool 2.0 （RoB2） was used to assess the quality and risk of bias of the methodology. Revman 5.4.1 software was used to analyze the outcome indicators. Grading of Recommendations Assessment，Development and Evaluation （GRADE） was applied to assess the quality of evidence formed by clinical research data. The inclusion and recommendation of Chinese patent medicines in the National Drug Catalogue for Basic Medical Insurance，Work-related Injury Insurance and Maternity Insurance （2022） and domestic guidelines and consensus were searched to form a bubble chart. ResultA total of 15 studies were included. The evaluation of the methodological quality of each study showed that the risk of bias stemmed from the lack of blinding and allocation concealment，and low sample size. The comprehensive analysis of clinical studies showed that Dengzhan Shengmai capsules combined with rosuvastatin and amlodipine besylate，Yindan Xinnaotong capsules combined with simvastatin and levamlodipine tablets，Xiaoshuan Tongluo capsules combined with nifedipine controlled release tablets and pravastatin sodium tablets，Xinshubao capsules combined with atorvastatin calcium tablets and irbesartan，Wenyading capsules combined with enalapril，and Jiangzhining tablets combined with conventional Western medicines were all superior to conventional Western medicines used in the control group in improving systolic blood pressure （SBP），diastolic blood pressure （DBP），cholesterol （TC），triglyceride （TG），low density lipoprotein cholesterol （LDL-C），and high density lipoprotein cholesterol （HDL-C）. There was no significant difference in the incidence of adverse reactions between the two groups. The GRADE evaluation of the main outcome indicators showed that the evidence quality of SBP and incidence of adverse reactions was graded as B，that of DBP as C，and that of total TC，TG，LDL-C，and HDL-C as D. The evaluation of Chinese patent medicines covered by medical insurance and recommended by guidelines and consensus showed that Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules belonged to class B drugs of medical insurance，and were recommended for 7，6 and 3 times in the guidelines and consensus，respectively. ConclusionCompared with simple medicine treatment，Chinese patent medicine combined with conventional Western medicine has more advantages in improving blood pressure and blood lipid，and shows higher safety. Among them，Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules have stronger clinical applicability and economy. All the trials included in this article adhered to the principle of randomization and reported the outcome measures. However，the quality of evidence in related clinical studies was low. In terms of trial design，large-sample，multi-center，blinded randomized controlled trials based on the consolidated standards of reporting trials （CONSORT） statement are still needed for comprehensive trial designs and reporting，to further improve the GRADE quality evaluation and guideline formulation under the guidance of evidence-based medicine，so as to provide higher quality evidence-based research evidence for clinical decision-making.

ObjectiveTo evaluate the quality of research and evidence related to antihypertensive Chinese patent medicines combined with western medicines for the treatment of hypertension， synthesize and update the evidence， form expert consensus， and provide evidence for clinical decision-making. MethodThe databases of China National Knowledge Infrastructure （CNKI）， WanFang Data Knowledge Service Platform （WanFang）， Vip Chinese Science and Technology Journal Database （VIP）， Chinese Biomedical Literature Service System （Sinomed）， National Library of Medicine （PubMed）， Cochrane Library， Web of Science， and US Clinical Trials Registry were searched for randomized controlled trials of antihypertensive Chinese medicine combined with western medicine for the treatment of hypertension from database construction to July 31， 2022. The quality of the literature was evaluated using the bias risk assessment tool in Cochrane Handbook 6.3. Evidence synthesis of main outcome indicators was performed using R software. The Grading of Recommendations Assessment， Development， and Evaluation profiler （GRADEprofiler） 3.6 was employed to evaluate the quality of evidence. Expert consensus was formed based on the Delphi method after two rounds of voting. Result64 pieces of literature were included， and the results of literature quality evaluation and risk of bias showed that 70.31% （45/64） of the studies indicated some risks， and 29.69% （19/64） indicated high risks. Compared with conventional western medicines， the combination of Chinese patent medicines with western medicines can significantly lower systolic pressure （SBP） and diastolic pressure （DBP）， increase the effective rate of antihypertensive， reduce the incidence of adverse reactions， endothelin-1， and traditional Chinese medicine syndrome scores. Egger's test showed that Songling Xuemaikang capsules reduced SBP and DBP. Tianma Gouteng granules reduced SBP and DBP and increased the effective rate of antihypertensive， and Xinmaitong capsules reduced SBP and increased the effective rate of antihypertensive， without significant publication bias. Songling Xuemaikang capsules increased the effective rate of antihypertensive， and Xinmaitong capsules decreased DBP， with significant publication bias. The results of the GRADE evidence quality evaluation showed that most evidence was at grades B and C. Finally， four strong recommendations and 14 weak recommendations were formed. ConclusionCompared with conventional western medicines for the treatment of hypertension， antihypertensive Chinese patent medicines combined with western medicines have advantages in reducing blood pressure and improving drug use safety， but they are mostly weak recommendations in terms of efficacy， and more high-quality evidence is needed.

ObjectiveTo systematically collect， analyze， and evaluate the randomized controlled trials （RCT） of Chinese patent medicine combined with western medicine in the treatment of hypertension， map the evidence， and provide reference for the future clinical research and formulation of guidelines and policies. MethodThe relevant articles were retrieved from China Biology Medicine disc， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， PubMed， Embase， and Cochrane Library with the time interval from inception to December 31， 2022. The RCT of Chinese patent medicines combined with western medicine in the treatment of hypertension were included. The research characteristics and methodological quality were analyzed and evaluated. ResultA total of 330 RCTs of treating hypertension with Chinese patent medicines combined with Western medicine were included in this study， all of which were published in Chinese. These RCTs involved 88 Chinese patent medicines and 37 788 patients， and 46% of RCT had the sample size ≥100 patients. Eighty-seven percent of RCT showed the study period within 3 months. All the interventions in the RCTs were Chinese patent medicine + western medicine vs western medicine. Among the evaluation indicators， blood pressure， response rate， TCM syndrome score， endothelial cell function， and safety were mainly concerned. In terms of methodological quality， most articles did not mention the generation of random sequences， allocation concealment， or blinding method. The blinding evaluation of outcomes showed low risks of bias， and there was insufficient information to judge whether there was selective bias or other bias. ConclusionThere were many Chinese patent medicines used in combination with western medicine in the treatment of hypertension， and they were mainly taken orally. The existing RCT had problems such as small sample size， unclear clinical value positioning， imperfect design failing to reflect the value of Chinese patent medicines， unreasonable measurement indicators， and non-standard measurement methods. Future research should solve the above problems， improve the research quality， value， and authenticity， and enhance the reliability and extension of evidence.

Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.

Objective:To investigate the comorbidity status of hypertension, diabetes, and dyslipidemia (the"three diseases") among residents aged≥40 in Liaoning Province, and to explore the correlation between the comorbidity and cardiovascular disease mortality.Methods:This investigation was a prospective cohort study. From February 2017 to March 2019, a multi-stage stratified cluster random sampling method was used to carry out a baseline survey of 18 758 permanent residents aged≥40 years in Liaoning Province. Demographic information and history of hypertension, diabetes, and dyslipidemia were collected and followed up every year. Death was mainly identified by linkage to the Population Death Information Registration Management System. Cox proportional hazard regression model was used to analyze the association between the comorbidity of the "three diseases" and cardiovascular disease mortality risk.Results:A total of 18 758 residents aged≥40 in Liaoning Province were included, with an age of (60.3±9.9) years and 7 325 males (39.1%). The comorbidity rate of hypertension, diabetes, and dyslipidemia was 6.7% (1 256/18 758), and the standardized prevalence rate was 5.4%. The comorbidity rate increased with age (P<0.001), which was higher in women than in men, and more significant in urban areas than in rural areas (all P<0.001). The comorbidity of "three diseases" accounted for 39.3% (1 256/3 198), 18.7% (1 256/6 710), and 11.8% (1 256/10 653) in patients with diabetes, dyslipidemia, and hypertension, respectively. With a follow-up of (4.3±0.6) years, 463 people died of cardiovascular disease. The mortality rate of cardiovascular disease in the comorbidity of hypertension, diabetes, and dyslipidemia was 8.74/1 000 person-years. After adjusting potential confounders, Cox proportional hazard regression model analysis showed that compared with normal individuals, the hazard ratio of cardiovascular disease mortality in patients with the "three diseases" was 2.55 (95% CI: 1.63-3.99). Conclusion:The prevalence of comorbidity of hypertension, diabetes, and dyslipidemia among residents aged≥40 in Liaoning Province was relatively high, and the risk of cardiovascular disease mortality in patients with the "three diseases" was increased.

In order to solve the problem of strong subjectivity and difficulty in quantification,clinical objectification mainly adopts the techniques of image processing,computer vision and machine learning.The acquisition and processing of prior knowledge is a key link in the objectification of inspection,as well as an important elaboration of the quantification of subjective judgment and macro performance in objectification research.However,there is still a lack of in-depth summary and parametric processing of prior knowledge.Based on the analysis of the current research status of objectification of inspection,this paper uses data mining technology to summarize the experience of TCM inspection.Moreover,the observation information can be transformed into quantifiable digital features through natural language processing and representation learning.Meanwhile,the application of deep learning can realize automatic diagnosis and analysis of observation images to improve accuracy and efficiency,and promote the process of TCM modernization.

Objective:To analyze the clinical characteristics and prognosis of patients with stiff-person syndrome (SPS) associated with glutamic acid decarboxylase (GAD) antibodies.Methods:A retrospective analysis was conducted on demographic characteristics, clinical manifestations, auxiliary examination results, treatment, and prognosis of patients with GAD antibody-related SPS treated at Peking Union Medical College Hospital from January 2015 to July 2023.Results:A total of 33 patients were included, comprising 26 females (78.8%) and 7 males (21.2%), with an onset age of (42±12) years and a disease duration of 24.0 (10.5, 37.5) months. Two cases (6.1%) were diagnosed with tumors, including 1 case with invasive thymoma and 1 case with small cell lung cancer. The majority of patients (87.9%, 29/33) presented with stiffness of trunk and proximal limb muscles, 42.4% (14/33) of patients exhibited episodic spasm, and 54.5% (18/33) of patients were triggered by stimuli such as sound and light. Babinski or Chaddock reflexes were elicited in 33.3% (11/33) of patients. Some patients (36.4%, 16/33) had concurrent limbic encephalitis/epilepsy or cerebellar ataxia (referred to as complex SPS). The median cerebrospinal fluid (CSF) white blood cell count was 2×10 6/L [quartile: 1×10 6/L, 6×10 6/L; range: (0-30)×10 6/L], with mild elevation in 28.0% (7/25) of patients. Multi-channel surface electromyography in 14 out of 21 cases (66.7%) suggested synchronous contraction of agonist and antagonist muscles in a relaxed state. The modified Rankin Scale (mRS) score during the acute phase was 4 (3, 4). All patients received treatment with benzodiazepines or baclofen. Thirty patients (90.9%, 30/33) received first-line immunotherapy, 3 patients (9.1%, 3/33) received second-line immunotherapy with rituximab, and 14 (42.4%, 14/33) received mycophenolate mofetil as long-term immunotherapy. The follow-up period was 16 (10, 42) months, with a median best mRS score of 2; 66.7% (22/33) of patients had a favorable functional prognosis (mRS score≤2), and the recurrence rate was 30.0% (9/30). At the last follow-up, the median mRS score was 2, and 53.3% (16/30) of patients had a favorable functional prognosis. Prognosis was not significantly correlated with gender, age, clinical type, or CSF white blood cell level (all P>0.05). Conclusions:SPS is one of the main clinical phenotypes of GAD antibody-related neuroimmune diseases, commonly observed in middle-aged women, and exhibits a chronic progressive course. Only a minority of patients have concomitant tumors. The diagnosis relies on typical symptoms, GAD antibody testing, and electromyography examination. The initial immune therapy yields good results, but the prognosis for recurrent patients is poor.
