OBJECTIVE To investigate a dynamic monitoring of drug consumption （DMDC） model based on the seasonal Mann-Kendall trend test， aiming to provide scientific evidence for the efficient and macroscopic monitoring of drug use. METHODS A monitoring list of key outpatient drugs was established based on the top 20% of drugs ranked by sales volume in the outpatient pharmacy in October 2024. A DMDC model based on the Mann-Kendall trend test was constructed using the monthly usage data of key outpatient drugs from November 2021 to October 2024， aiming to eliminate the impact of seasonal fluctuations and analyze the temporal trends in drug consumption. Taking mucolytic expectorants， triazole derivatives for dermatophytosis， and single-agent hydroxymethylglutaryl coenzyme A （HMG-CoA） reductase inhibitors as examples， the monitoring effectiveness of the DMDC model was demonstrated， and its performance was compared with that achieved by the traditional sequential growth rate ranking method. RESULTS A total of 215 drug varieties were included in the monitoring list， and DMDC models were successfully established for all of them. Among these， 119 showed a significant increasing trend （P＜0.05， S′＞0）. The model successfully monitored the monthly consumption of mucolytic expectorants， triazole derivatives for dermatophytosis， and single- agent HMG-CoA reductase inhibitors. The precision and recall rates of the DMDC model for identifying abnormal drug use were 60.7% and 85.0%， respectively， both significantly higher than those of the sequential growth rate ranking method （8.3% and 15.0%， respectively） （χ2＝20.114， P＜0.001； χ2＝19.600， P＜0.001）. CONCLUSIONS DMDC model based on the seasonal Mann-Kendall trend test can effectively identify long-term trends in drug consumption， eliminate seasonal interference， enhance monitoring accuracy and management efficiency， and is suitable for the dynamic monitoring of drug consumption.

Objective To design and evaluate the clinical application efficacy of a novel bilateral-separation endotracheal tube fixation device and provide references for clinical practice.Methods Using convenient sampling,60 patients from the Neurological Intensive Care Unit of a tertiary-level hospital in Zhengzhou were selected from May to December 2024.Patients were randomly divided into an experimental group(n=30)and a control group(n=30).The experimental group utilized the novel bilateral-separation endotracheal tube fixation device,while the control group employed traditional bandage fixation methods.Differences in fixation time,tube displacement,and intubation duration were compared between the 2 groups.Results The experimental group demonstrated significantly shorter tube fixation times compared to the control group(P＜0.05).However,no statistically significant differences were observed between the groups regarding intubation duration and tube displacement(P＞0.05).Conclusion The novel bilateral-separation endotracheal tube fixation device can reduce tube fixation time for patients in neurological intensive care and enhance nurse satisfaction.Despite not showing advantages in preventing tube displacement,the device still presents promising potential for broad clinical application.

Based on WANG Xugao's"thirty liver-regulating methods,"this paper summarized the clinical thinking of treating diabetic kidney disease from the liver.The liver is closely associated with the pathogenesis of diabetic kidney disease,including internal heat,essence depletion,latent wind,and the accumulation and dissipation of a conglomeration of kidney collateral zhengjia.WANG Xugao's"thirty liver-regulating methods"comprehensively reveals the physiological and pathological changes of the liver,as well as clinical approaches for liver treatment.Liver qi stagnation can lead to the generation of internal heat,liver stagnation and deficiency can cause essence depletion and collateral obstruction,and disharmony of the liver wood can cause internal wind disturbance,which all contribute to the progression of diabetic kidney disease at different stages.Treatment generally follows the essence of"thirty liver-regulating methods."In the early stage,treatment should focus on treating liver heat by soothing the liver qi,clearing the liver fire,and removing damp-heat to resolve stagnation and heat.In the middle stage,treatment should focus on treating liver deficiency by nourishing the liver yin to clear heat,replenishing the essence and blood to tonify deficiency,and promoting blood circulation to remove stasis,thereby strengthening the foundation and nurturing the primal essence.In the later stage,treatment should focus on treating liver wind to prevent complications and improve the patient's quality of life.Throughout the entire process,liver collaterals are treated using pungent herbs to invigorate qi and open the liver channels,relieving blood stasis and promoting circulation.In conjunction with the above methods,flexible selection of effective formulas and drug pairs should be used,each addressing specific treatment goals.

Diabetic kidney disease(DKD),a prevalent complication of diabetes mellitus,remains a leading cause of end-stage renal disease.Recent research has identified lipophagy,a novel mechanism in DKD pathogenesis,drawing increasing attention in the field.This paper explores the biological connotation of the"internal heat leading to Zheng"pathogenesis based on lipophagy.The study proposes that lipophagy represents the microscopic biological correlation of liver-spleen coordination in regulating spleen transport and the ascending-descending dynamics of the middle jiao.Under persistent hyperglycemia,the suppression of lipophagic activity mirrors the traditional Chinese medicine(TCM)pathophysiological process described as"excessive fire consuming healthy qi,"whereas aberrant lipid accumulation in the kidney corresponds to the dynamic aggregation and dispersion of micro-zhengjia.Lipotoxicity,a key driver of DKD progression,is interpreted as the biological manifestation of accumulated turbidity transforming into toxicity,resulting in progressive impairment of renal essence and function.The dynamic process of lipophagy dysfunction under hyperglycemia,marked by renal microangiopathy,glomerular and tubular dysfunction,and renal fibrosis,closely mirrors the pathological evolution of"micro-zhengjia"and"internal heat leading to Zheng."Consequently,TCM strategies for DKD prevention and treatment should emphasize heat regulation,stage-specific interventions,liver-spleen harmonization,metabolic modulation,early collateral protection,and blood-activating approaches.

OBJECTIVE To construct an insulin-resistant(IR)small intestinal organoid model of mice and study the protective effect of flavanomarein(FM)on the intestinal mucosal barrier in the model.METHODS ①Small intestinal organoid models of C57BL/6J and db/db of mice were constructed.The expressions of Ki-67,E-cadherin(E-cad),lysozyme(Lyz)and mucin-2(Muc-2)in small intestinal organ-oids were detected by 3D immunofluorescence.RT-qPCR was used to detect the expressions of fibro-nectin(Fn),glucagon-like peptide-1(GLP-1)and peotide YY(PYY)mRNA while Western blotting was used to detect the expressions of Fn,GLP-1 and PYY protein.The Lyz secretion level was detected by ELISA.② Small intestinal organoids were divided into five groups:C57BL/6J mice 'small intestinal organ-oids as the normal control group,db/db mice' intestinal organoids as the IR model group,db/db mice small intestinal organoids with flavanomarein 25,50 and 100 μmol·L-1 intervention for 48 h as IR model+ FM groups.RT-qPCR was used to detect the expression of Lyz mRNA while Western blotting was used to detect the expression of Lyz protein.RESULTS ① On the 6th day of small intestinal organoid culture,a ring structure with a clear luminal structure was formed and an IR mouse small intestinal organoid model was established.3D Immunofluorescence detection showed that the established small intestinal organoids all expressed Ki-67,E-cad,Lyz and MUC-2.Compared with the normal control group,the expres-sion of Fn mRNA in the IR model group was significantly increased(P<0.05)while the expressions of GLP-1 and PYY mRNA were significantly decreased(P<0.05).Compared with the normal control group,the expression of Fn protein in the IR model group was significantly decreased(P<0.05)while the expressions of GLP-1 and PYY protein were significantly increased(P<0.05).ELISA results showed that compared with the normal control group,the secretion levels of Lyz in the IR model group were signifi-cantly decreased(P<0.01).② RT-qPCR results showed that compared with the normal control group,the expression of Lyz mRNA in the IR model group was significantly decreased(P<0.01).Compared with the IR model group,the expression of Lyz mRNA in the IR model+FM 50 and 100 μmol·L-1 groups was significantly increased(P<0.05,P<0.01).Western blotting results showed that compared with the normal control group,the expression of Lyz protein in the IR model group was significantly decreased(P<0.01).Compared with the IR model group,the expression of Lyz protein in the IR model+FM 50 and 100 μmol·L-1 groups was significantly increased(P<0.05,P<0.01).CONCLUSION The constructed IR mouse small intestinal organoid model provides a more complete in vitro research model for exploring the pathophysiological mechanism by which drug interventions help repair the intestinal mucosal barrier.FM may maintain the intestinal mucosal barrier by reversing the decrease in Lyz expression levels in IR mice,thereby improving IR.

As a supplement to randomized controlled trials， observational studies can provide evidence for the effectiveness of traditional Chinese medicine （TCM） treatment measures. They can also study influencing factors of diseases， etiology， and prognosis. However， there is a confounding effect due to the lack of randomization， which seriously affects the causal inference between the study factors and the outcome， resulting in confounding bias. Therefore， identifying and controlling confounding factors are key issues to be addressed in TCM observational studies. According to the causal network and the characteristics of TCM theory， confounding factors can be categorized into measured and unmeasured confounding factors. In addition， attention must be paid to identifying confounding factors and intermediate variables， as well as the interaction between confounding factors and study factors. For methods of controlling confounding factors， measured confounding factors can be controlled by stratification， multifactor analysis， propensity scores， and disease risk scores. Unmeasured and unknown confounding factors can be corrected using instrumental variable methods， difference-in-difference methods， and correction for underlying event rate ratios. Correcting and controlling confounding factors can ensure a balance between groups， and confounding bias can be reduced. In addition， methods such as sensitivity analysis and determination of interactions make the control of confounding factors more comprehensive. Due to the unique characteristics of TCM， observational studies of TCM face unique challenges in identifying and controlling confounding factors， including the ever-changing TCM treatment measures received by patients， the often-overlooked confounding effects in the four diagnostic information of TCM， and the lack of objective criteria for TCM evidence-based diagnosis. Some scholars have already conducted innovative explorations to address these issues， providing a methodological basis for conducting higher-quality TCM observational studies， so as to obtain more rigorous real-world evidence of TCM and gradually develop quality evaluation criteria for OS that are consistent with the characteristics of TCM.

WANG Qishi put forward the theory of "yang deficiency with three lackings， controlled by the spleen" in Lixu Yuanjian （《理虚元鉴》）， which regarded that yang deficiency can lead to consumptive diseases with changes of lacking essence， lacking qi， and lacking fire， so the treatment should start from the spleen to restore the middle yang urgently. This article summarised the experience of treating type 4 cardiorenal syndrome based on the theory of "yang deficiency with three lackings， controlled by the spleen"， and proposed that lacking essence is the beginning of the onset of type 4 cardiorenal syndrome， lacking qi is the gradual development of the disease， and lacking fire is the changes of the disease， and ultimately resulted in the complex situation of kidney and qi deficiency， and edema due to yang deficiency， combined with syndromes variation. In the clinical evidence， in the stage of lacking fire， therapies should warm the middle and strengthen the spleen in order to rescue the middle yang， prescribed with modified Baoyuan Decoction （保元汤） plus Lizhong Decoction （理中汤）； in the stage of lacking qi， prescriptions can add Taoren （Juglans regia）， Tubiechong （Eupolyphaga sinensis）， Fuling （Smilax glabra）， Guizhi （Neolitsea cassia） to activate blood and drain water to transport and restore the center qi； in the stage of lacking essence， prescriptions can add Gouqizi （Lycium barbarum）， Tusizi （Cuscuta chinensis）， Duzhong （Eucommia ulmoides）， Bajitian （Gynochthodes officinalis） to supplement deficiency and resolve masses to consolidate the root and supplement essence.
