ObjectiveTo investigate the effect of Dingzhi Xiaowan （DZXW） in post-stroke cognitive impairment （PSCI） model mice. MethodsThe cerebral ischemia-reperfusion injury model of mice was established by using the middle cerebral artery occlusion method. Forty C57BL/6 male mice were randomly divided into the sham operation group， model group， low-dose DZXW group （1.43 g·kg^-1）， and high-dose DZXW group （2.56 g·kg^-1）， with 10 mice in each group. Both the sham operation group and the model group were treated with equal amounts of normal saline by gavage， and the above four groups of mice were gavaged once a day for 30 consecutive days. Morris water maze test was used to evaluate the learning memory ability of mice. Serum levels of amyloid precursor protein （APP）， amyloid 42 （Aβ₄₂）， acetylcholinesterase （AChE）， and superoxide dismutase （SOD） were measured by enzyme-linked immunosorbent assay （ELISA）. Deoxyribonucleotide end transferase-mediated nick end labelling （TUNEL） assay was applied to detect the degree of apoptosis in the mouse's hippocampal neurons. Western blot was used to detect the protein expression of phosphoinositol-3 kinase （PI3K）， protein kinase B （Akt）， mammalian target of rapamycin （mTOR）， hypoxia-inducible factor 1-alpha （HIF-1α）， B-cell lymphoma 2 （Bcl-2） homologous structural domain protein （Beclin1）， sequestosome 1 （p62）， microtubule-associated protein light chain 3 （LC3）， Bcl-2， and Bcl-2-associated X protein （Bax） in hippocampal tissue. Prussian blue staining was used to detect iron deposition in hippocampal tissue. Transmission electron microscopy was taken to observe the ultrastructure of the mouse's hippocampal neurons. ResultsCompared with the sham operation group， the latency， APP， Aβ₄₂， AChE， TUNEL positivity， ferric ion deposition， HIF-1α， Beclin1， Bax， and LC3Ⅱ/Ⅰ were significantly increased in the model group （P<0.01）， while the number of crossing platforms， SOD， p-PI3K， p-Akt， p-mTOR， p62， and Bcl-2 were significantly decreased （P<0.01）. Compared with the model group， the latency， APP， Aβ₄₂， AChE， TUNEL positivity rate， ferric ion deposition， HIF-1α， Beclin1， Bax， and LC3Ⅱ/Ⅰ were significantly reduced in the DZXW groups （P<0.05）， while the number of crossing platforms， SOD， p-PI3K， p-Akt， p-mTOR， p62， and Bcl-2 were significantly higher （P<0.05）. ConclusionDZXW can alleviate cognitive impairment induced by oxidative stress-aggravated hippocampal neuronal damage in PSCI model mice by modulating the PI3K/Akt/mTOR/HIF-1α autophagy signalling pathway.

Osteoarthritis （OA） and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan， a classic prescription in Tibetan medicine， have the functions of clearing heat， awakening the brain and opening orifices， relaxing tendons and promoting meridian circulation， and eliminating yellow water. Clinically， they are used to treat osteoarthritis， post-stroke sequelae， neuropathic pain， and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory， analgesic， and nerve-repairing effects. However， current research remains insufficient regarding the appropriate indications， timing， and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use， a panel of national experts， including clinical specialists， Tibetan medicine practitioners， pharmacologists， and methodologists， formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system， and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan， including therapeutic indications， dosage and administration， treatment duration， and medication safety. The consensus specifically addresses the clinical efficacy， appropriate timing of administration， dosage strategies， treatment cycles， and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke， reduce medication-related risks， and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine， with the standard number GS/CACM 369-2024.

ObjectiveTo optimize the processing technology of honey bran-fried Rosae Laevigatae Fructus（h-RLF）， formulate relevant quality standards， and explore its improving effect and mechanism on mice with ulcerative colitis（UC） induced by dextran sodium sulfate（DSS）. MethodsTaking the content of polysaccharides and water-soluble extract as the indexes， L₉（3⁴） orthogonal test was used to optimize parameters of the amount of honey bran， frying time and frying temperature. The quality of 15 batches of h-RLF decoction pieces was evaluated according to the optimized process， and the inspection limit standard was preliminarily drawn up. Eighty SPF male Kunming mice were randomly divided into 8 groups， including the blank group， model group， mesalazine group（0.13 g·kg^-1）， RLF group（3.77 g·kg^-1）， bran-fried RLF group（3.77 g·kg^-1）， h-RLF low， medium and high dose groups（1.89， 3.77， 7.54 g·kg^-1）， with 10 mice in each group. The mice in the blank group were free to drink pure water， and the other groups were free to drink 3% DSS solution for 7 days to prepare UC mouse model. Each treatment group was given corresponding drugs by intragastric administration， and the blank and model groups were given equal volume of normal saline. The body weight of mice was recorded daily and the disease activity index（DAI） was calculated. After the administration， the colon tissues of mice were collected to observe the pathological changes by hematoxylin-eosin（HE） staining. The levels of tumor necrosis factor（TNF）-α， interleukin（IL）-1β， IL-6 and IL-10 in the colon of mice were detected by enzyme-linked immunosorbent assay（ELISA）. Western blot was used to detect the expression levels of phosphorylation nuclear transcription factor-κB p65（p-NF-κB p65）， Toll-like receptor 4（TLR4）， p-p38 mitogen-activated protein kinase（p-p38 MAPK）， p-extracellular signal-regulated kinase（p-ERK） and p-c-Jun N-terminal kinase（p-JNK） proteins in colon tissues. ResultsThe optimum processing technology of h-RLF was 20 g honey bran per 100 g RLF， and stir-frying at 200 ℃ for 8 min. The limit standard under the examination of h-RLF was preliminarily formulated as follows：the polysaccharide content should not be less than 25% based on anhydrous glucose（C₆H₁₂O₆）， the content of water-soluble extract should not be less than 38%， the moisture content should not be more than 12.0%， the total ash content should not be more than 5.0%， and the acid-insoluble ash content should not be more than 1.0%. The cluster heat map analysis showed that the quality of RLF from Huanggang， Hubei province was better. Animal experiments showed that compared with the blank group， the DAI score of the model group was significantly increased， the levels of TNF-α， IL-1β and IL-6 in the colon tissue were significantly increased， the IL-10 level was significantly decreased， the colonic mucosa was seriously damaged， accompanied by a large number of inflammatory cell infiltration， tissue congestion and a significant reduction in glands， and the expression levels of p-NF-κB p65， TLR4， p-p38 MAPK， p-ERK and p-JNK proteins were significantly increased（P<0.01）. Compared with the model group， each administration group could alleviate the symptoms of colonic ulcer， the structure of colonic crypt was basically intact， and the glands were arranged in an orderly manner. Among them， the high-dose group of h-RLF had a better effect， which could significantly reduce the DAI score and the levels of TNF-α， IL-1β and IL-6 in colon tissue（P<0.01）， and significantly increase the level of IL-10（P<0.01）， alleviate the colonic mucosal injury， and effectively inhibit the expression levels of p-NF-κB p65， TLR4， p-p38 MAPK， p-ERK and p-JNK proteins（P<0.01）. ConclusionThe key parameters of the processing technology of h-RLF are determined， and the optimized technology is stable and feasible. The established quality standard is simple and reliable， and can be used for the quality control. h-RLF can effectively alleviate DSS-induced UC， and its mechanism may be related to inhibiting the activation of NF-κB/TLR4/MAPK pathway.

OBJECTIVE To analyze the correlation of the peak blood concentration （cmax） of compound sulfamethoxazole （TMP/SMZ） and its metabolite N-acetyl sulfamethoxazole （NSMZ） with clinical efficacy and adverse reactions in critically ill patients. METHODS The data of critically ill patients treated with TMP/SMZ in various ICU of Hainan General Hospital from December 2023 to January 2025 were retrospectively collected. The patients were divided into success group and failure group based on the treatment outcome. Simple linear regression and Spearman correlation analysis were used to analyze the correlation of TMP cmax， SMZ cmax， and NSMZ cmax with clinical efficacy and adverse reactions. The receiver operating characteristic curve （ROC） was used to determine the cutoff values of cmax for predicting the occurrence of adverse reactions. RESULTS Among critically ill patients with an acute physiology and chronic health evaluation Ⅱ （APACHE-Ⅱ） ≥15 points 24 h of check-in at ICU， SMZ cmax of success group was significantly higher than failure group （P＜0.05）. The daily total dose of TMP/SMZ was positively correlated with TMP cmax and SMZ cmax（ P＜0.05）. TMP cmax was significantly correlated with hepatotoxicity and nephrotoxicity， SMZ cmax with hepatotoxicity， and NSMZ cmax with nephrotoxicity （P＜0.05）. The cutoff values of TMP cmax for predicting nephrotoxicity and hepatotoxicity were 7.25 μg/mL and 6.63 μg/mL， respectively. The cutoff value of SMZ cmax for predicting hepatotoxicity was 138.00 μg/mL， and that of NSMZ cmax for predicting nephrotoxicity was 60.76 μg/mL. CONCLUSIONS Among critically ill patients with an APACHE-Ⅱ ≥15 points 24 h of check-in at ICU， SMZ cmax is associated with treatment success. Hepatotoxicity risk significantly increases when TMP cmax ≥6.63 μg/mL or SMZ cmax ≥138.00 μg/mL； nephrotoxicity risk significantly increases when TMP cmax ≥7.25 μg/mL or NSMZ cmax ≥60.76 μg/mL.

As the core technology of processing， the stir-frying method of traditional Chinese medicine（TCM） realizes the regulation of efficacy of medicinal substances through the coordination of fire gradient and excipients. This study aims to systematically analyze the influence of different stir-frying degrees（stir-frying until yellow， stir-frying to brown， stir-frying to charcoal） and excipient types（solid excipients such as rice， wheat bran， soil， liquid excipients such as rice wine， vinegar， honey） on the physicochemical properties， efficacy and toxicity of TCM， summarizing their common regulatory mechanisms and characteristics. Then， the three-dimensional regulatory common mechanisms and five-dimensional regulatory specificity mechanisms of different stir-frying processes were obtained. The three-dimensional regulatory common mechanisms are as follows：①Thermal effects break down inherent barriers of medicinal materials and improve the dissolution of components. ②Inducing Maillard reaction， carbonization and other reactions of medicinal materials to promote the transformation of components. ③Combining the catalytic and harmonizing effects of excipients to achieve targeted enrichment of efficacious substances and precise control of toxic components. The five-dimensional regulatory specificity mechanisms manifest as：①The efficacy gradient pattern where stir-frying until yellow strengthens the spleen， stir-frying to brown aids digestion， and stir-frying to charcoal stops bleeding. ②According to the polarity difference and intrinsic properties， the liquid excipients form a directional synergistic mechanism of wine processing enhances ascending nature， ginger processing to warm and disperse， salt processing directs effects to the kidneys， vinegar processing targets the liver， honey processing imparts sweetness and moderation. ③Through porous structure and interfacial properties， solid excipients give the synergistic effect of rice processing for diarrhea relief， bran processing for stomach tonification， soil processing for warming the middle warmer， and clam powder/talcum powder/sand processing for texture optimization. ④Thermal effects induce decomposition/oxidation/polymerization and other reactions to reshape the material basis， directing changes in the efficacy. ⑤The targeted distribution of efficacy is regulated by component enrichment and meridian-guiding effect， and the meridian tropism is changed. The system， driven by thermal effect， excipient synergy and physicochemical reconstruction， integrates five-dimensional regulation of fire， solvent， interface， composition and distribution. It systematically explains the inherent law of efficacy-substance-process of traditional stir-frying， and provides theoretical basis and practical guidance for standardizing TCM processing and enhancing the efficacy.

Fermentum Rubrum（FR） is a kind of traditional Chinese medicine with dual-use functions of medicine and food， which has been used for more than 1 000 years. By referring to the ancient herbal classics and modern laws and regulations， the author sorted out the origin of FR， sorted out the development of processing， and analyzed the problems existing in the quality standard， aiming to provide a basis for further research and development of FR. There are many theories about the origin of FR. After summarizing and sorting out the relevant literature， three viewpoints are mainly drawn， including Han dynasty origin theory， Wei and Jin origin theory and Tang dynasty origin theory. After synthesizing the views of various schools， it is believed that the origin of FR should be no later than the Eastern Han dynasty. FR is made from rice by fermentation， which has the effect of strengthening the spleen， eliminating food， promoting blood circulation and removing stasis after fermentation. Although the natural fermentation in ancient times has been able to pay attention to the influence of temperature， humidity and strain on the quality of FR， due to the low level of science and technology， there are still problems such as complicated and cumbersome process， large workload and high labor cost. To the pure fermentation in modern times， the fermentation processing method of FR has been evolved， gradually improved and perfected. However， due to the lack of standardized research， there is no unified standard for the fermentation process of FR in various regions， and the quality standard lags behind seriously， which leads to the unstable product quality on the market. Among the 15 specifications for the preparation of FR， only 6 have been published in the past 5 years， and most of them have not been revised in a timely manner， and some of them have not been included in the updated version. Based on this， it is recommended to carry out a systematic study on processing technology of FR， and the best process is selected to accelerate the revision and improvement of its standardization， so as to improve the quality of FR sold in the market and promote its stable and sustainable development.

Objective To explore the feasibility and safety of MCCE in gastrointestinal examination of elderly patients with malignant tumors.Methods Clinical data of 127 patients who underwent MCCE examination from April 2019 to September 2022 were retrospectively analyzed.According to age,the patients were divided into the elderly group(age≥65 year-old,n = 88)and the middle-aged group(40≤age<65 year-old,n = 39),and the clinical data of patients with malignant tumors were screened from the two groups for analysis and comparison.Results 131 patients received MCCE examination,and 4 elderly patients were excluded from this study due to swallowing failure,so 88 elderly patients were actually included in the study.In the elderly group,45.4%had serious cardiovascular diseases(40/88),27.3%had malignant tumors(24/88),8.0%had serious respiratory diseases(7/88),6.8%had anesthesia problems(6/88),and 9.1%had neurological diseases(8/88).Among the 24 elderly patients with malignant tumors,25.0%had severe cardiovascular disease,25.0%had poor general status,20.8%had brain metastases,and 12.5%had severe respiratory dysfunction.The positive diagnosis rate of gastric P2 lesions in the elderly group(52/88,59.1%)was significantly higher than that in the middle-aged group(13/39,33.3%)(P = 0.013).There was significant difference in positive rate of ulcer diagnosis between the two groups(29.5%and 10.2%)(P = 0.032).In patients with malignant tumors,the positive rate of ulcer diagnosis between the two groups(45.8%and 11.1%)was statistically significant(P = 0.038).The cleanliness and visualization scores of proximal stomach in the middle-aged group were higher than those in the elderly group,and the differences were statistically significant(P<0.05).Conclusion MCCE is generally effective and safe in elderly patients,especially those with malignant tumors,without missing any significant gastric lesions.
