Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals", it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure, qi and liquid imbalance, and kidney collaterals impairment, and it is proposed that the treatment principle is to nourish the sweat pore, regulate qi and fluid, and supplement the kidney and unblock the collaterals. In clinic, guided by sequential therapy and according to the different disease mechanism characteristics of the four stages, including early stage of the disease, hormone induction stage, hormone reduction stage, hormone maintenance stage, the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency, modified Zhenwu Decoction (真武汤) was applied to warm yang and drain water; for hormone induction stage with yin deficiency resulting in effulgent fire, modified Zhibai Dihuang Pill (知柏地黄丸) plus Erzhi Pill (二至丸) was used to enrich yin and reduce fire; for hormone reduction stage with qi and yin deficiency, modified Shenqi Dihuang Decoction (参芪地黄汤) was used to boost qi and nourish yin; for hormone maintenance stage, modified Shenqi Pill (肾气丸) was used to supplement yin and yang. Meanwhile, the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals, so as to providing ideas for clinical treatment.

Diarrhea-irritable bowel syndrome (IBS-D) is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated, effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine (TCM) and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D, we discovered that rats were the preferred animals for modeling, and the models were mainly induced by single factors, double factors, or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition, the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency, and few models were established for the syndromes of spleen-kidney Yang deficiency, spleen-stomach dampness-heat, spleen deficiency and dampness excess, and cold and heat in complexity. Therefore, it is essential to improve the existing or develop new animal models of IBS-D in the future, so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

BackgroundRehabilitation for schizophrenia typically relies on pharmacological interventions, yet their efficacy in improving social function and quality of life remains limited. In recent years, non-pharmacological approaches have shown promise in enhancing rehabilitation outcomes. However, research on the effectiveness of psychomotor therapy specifically for young and middle-aged schizophrenic inpatients is limited. ObjectiveTo explore the effects of psychomotor therapy on the rehabilitation of young and middle-aged schizophrenic inpatients, and to provide a reference for treatment strategies. MethodsA total of 104 young and middle-aged schizophrenic inpatients who met the International Classification of Diseases,tenth edition (ICD-10) diagnostic criteria and hospitalized in the Fourth People's Hospital of Wuhu from June 2021 to June 2022 were selected. Patients were randomly divided into two groups of 52 each using random number table method. Both groups received treatment with risperidone tablets (2~4 mg/d) , along with routine nursing care. Additionally, the research group received an extra 45~55 minutes of psychomotor therapy 2~3 times per week for 12 weeks. The control group received the same psychomotor therapy after the study. Positive and Negative Symptom Scale (PANSS), Scales of Social-skills for Psychiatric Inpatient (SSPI) and Insight and Treatment Attitude Questionnaire (ITAQ) were used to assess the patients before the intervention and at 4th, 8th and 12th week after the intervention. ResultsThe main effects of intervention at different time points for PANSS positive symptoms, negative symptoms and general psychopathology subscale scores, PANSS total score, SSPI score and ITAQ score were all statistically significant (F=33.989, 204.245, 82.817, 279.596, 26.144, 7.463, P<0.01). Furthermore, statistically significant between-group differences were observed in PANSS negative symptoms and general psychopathology subscale scores, PANSS total score, SSPI score and ITAQ score (F=30.053, 5.306, 33.417, 33.013, 18.608, P<0.05 or 0.01). Moreover, the interaction effect of time and group were statistically significant for PANSS positive symptoms, negative symptoms and general psychopathology subscale score, PANSS total score and SSPI score (F=3.472, 9.798, 3.843, 14.390, 20.661, P<0.05 or 0.01). After 12 weeks of intervention, the research group exhibited statistically significantly lower PANSS total score and subscale scores compared with baseline (P<0.01), while their SSPI total score was significantly higher than that of control group(P<0.01). Additionally, compared with the control group, the research group had statistically significantly lower PANSS total score and subscale scores , while their SSPI score was statistically significantly higher than those of control group(P<0.01). ConclusionPsychomotor therapy may contribute to the improvement of the psychiatric symptoms and social function in young and middle-aged inpatients with schizophrenia, enhancing their rehabilitation outcomes.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The imprint desorption electrospray photoionization mass spectrometry was employed to locally image the spatial distribution of chemical components in dried tobacco leaves after initial curing. The relative content distribution of different chemical components was obtained in tobacco leaves. The application of imprinting method could transfer tobacco internal compounds to the surface of porous polytetrafluoroethylene plate,which realized the detection and visual analysis of tobacco internal substances. Besides,the imprint desorption electrospray ionization/post-photoionization (Imprint DESI/PI) mass spectrometry imaging technique had the advantages of non-polarity discrimination,soft ionization and high ionization efficiency for plant samples,and could simultaneously detect and image rich compounds in tobacco samples. A total of 40 kinds of chemical components including alkaloids,amino acids,sugars,acids,ketones and phenols were identified based on high resolution mass spectrometry. The results showed that the representative chemical components of tobacco,such as alkaloids,amino acids and sugars,were mainly distributed near the leaf tip from the vertical analysis and at the left and right leaf edges from the horizontal analysis. Amadori compound (1-Deoxy-1-L-proline-d-fructose) was detected,and the content of Amadori was found to be consistent with that of free amino acid (proline). In addition,the technique was further used to study the climate spot disease area of tobacco,and it was found that the compounds had specific distribution in the climate spot area,which further proved the superiority of this method in studying the growth stress of tobacco leaves.
