Liumotang comes from the Yuan dynasty's Effective Prescription Handed Down for Generations of Physicians. It is composed of six medicinal materials: Arecae Semen, Aquilariae Lignum Resinatum, Aucklandiae Radix, Linderae Radix, Rhei Radix et Rhizoma, and Aurantii Fructus. It is a classical formula for treating abdominal pain due to Qi stagnation and constipation accompanied by heat. This study systematically collated the records of Liumotang in ancient medical books and modern clinical literature and conducted in-depth analysis and textual research on its formula source, main diseases, composition, dosage, medical books, container capacity, processing, preparation method, usage, drug basis, formula meaning, and other key information, so as to provide a powerful reference for the development and clinical application of compound preparations of the classical formula Liumotang. The results show that Liumotang was first seen in Effective Prescription Handed Down for Generations of Physicians, and many medical books of the past dynasties have imitated this. In terms of drug basis, the dried and mature seeds of the palm plant Areca catechu, resin-containing wood of the Daphneaceae plant Aquilaria sinensis, the dried roots of the Asteraceae plant woody Aucklandia lappa, the dried tuber root of the Lauraceae plant Lindera aggregata, the dried roots and rhizomes of the knotweed plant, R. palmatum, R.tangutikum, and R. officinale, and the dried and unripe fruits of the citrus genus C. aurantium and its cultivated varieties from the family Rutaceae were selected. In terms of dosage, through the textual research on bowls in the Ming and Qing dynasties, combined with the conversion of medicines and bowl capacity in the Qing dynasty, it was estimated that the dosage of each drug in the Yuan dynasty was 10.86 g. In the Ming and Qing dynasties, the dosage of drugs was mostly equal, but the dosage of drugs was somewhat different. In terms of processing, preparation method, and usage, in the medical books of the past dynasties, the processing of drugs has slightly changed, but raw drugs are used in all preparations. The preparation method and usage did not change much during the Yuan, Ming, and Qing dynasties, except for certain differences in dosage. In terms of syndrome, Liumotang was first used to treat abdominal pain due to Qi stagnation and constipation accompanied by heat. Medical books of the past dynasties often omit the symptoms of heat. In modern clinical practice, Liumotang is mainly used in the digestive system and urinary system diseases and is mostly used to treat constipation-predominant irritable bowel syndrome, biliary reflux gastritis, functional constipation, slow transit constipation, and other diseases, with no adverse reactions found yet. The above results provide a reliable scientific basis for the development and clinical treatment of Liumotang compound preparations.

The prescription Mahuang Shengmatang in the Treatise on Cold Damage (《伤寒论》) has sparked considerable debate among medical practitioners throughout history, with varying opinions on its indications, pathogenesis described in the text, principle of compatibility, and clinical applications. Both ancient and modern interpreters of Mahuang Shengmatang often focus on herbal compatibility as a primary approach to deduce the pathogenesis and treatment methods. Building upon this foundation, this paper utilizes herbal dosage as a clue to discern the primary and secondary herbs in the prescription. It further analyzes the principle of compatibility based on herbal indications, summarizing the indications and therapeutic principles of this prescription. Ultimately, it reveals the underlying pathogenesis reflected in the text. The internal closure of heat and toxin leads to the stagnation of Qi, preventing Yang Qi from reaching the extremities and causing cold hands and feet. When the pathogenic Qi finds no outlet, it floods both the upper and lower regions of the body, attacking the throat and causing cough with expectoration of pus and blood, and descending to the large intestine to consume Yin fluids, resulting in persistent diarrhea. Based on this pathogenesis, the paper expands the scope of symptoms and signs associated with the prescription, providing a more detailed portrayal of the applicable patient population and enhancing the basis for clinical prescription references. Additionally, the paper presents considerations on several controversial topics, suggesting that the "lower pulse" described in the text refers to the lower limb arterial pulsation, and the symptoms and signs resemble those of septic shock in modern medicine. Therefore, Mahuang Shengmatang should be categorized as a prescription for treating warm diseases and it is not developed by ZHANG Zhongjing. By employing a detailed discussion on the syndrome, pathogenesis, and clinical application in the texts of Mahuang Shengmatang from the dosage, principle of compatibility, and herbal indications, this paper not only enriches the theoretical foundation of Mahuang Shengmatang but also provides a comprehensive perspective and fresh ideas for understanding its clinical application.

Precancerous lesions of gastric cancer (PLGC) are a group of pathological changes caused by abnormalities in the structure, morphology, and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific, PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly, the incidence of this disease is increasing year by year, which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex, involving inflammatory microenvironment, bile reflux, glycolysis, autophagy, and apoptosis. Currently, PLGC is mainly treated with anti-inflammatory and endoscopic therapies, which are difficult to curb the development of PLGC. Therefore, seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine (TCM), characterized by treatment based on syndrome differentiation and a holistic view, exerts effects via multiple pathways, mechanisms, and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR), Wnt/β-catenin, Sonic Hedgehog, nuclear factor-κB (NF-κB), Janus kinase/signal transducer and activator of transcription (JAK/STAT), hypoxia-inducible factor-1α (HIF-1α), neurogenic locus notch homolog protein (Notch), nuclear factor E2-related factor 2 (Nrf2) and other signaling pathways. By targeting these pathways, TCM can inhibit aerobic glycolysis, reduce oxidative stress, repair the inflammatory microenvironment, regulate cellular autophagy, and promote vascular normalization, thereby delaying or reversing PLGC. However, few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad, this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC, with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

How to effectively promote osseointegration of dental implants remains a pressing clinical challenge. Low-intensity pulsed ultrasound (LIPUS) has demonstrated remarkable efficacy in accelerating the healing of various bodily tissues, including bone tissue. In recent years, there has been extensive research on its application in promoting osseointegration in the field of dental implantology. Animal studies have shown that LIPUS exhibits significant potential in facilitating osseointegration of dental implants. In vitro experiments have further revealed that LIPUS can enhance the expression of key osteogenic factors, extracellular matrix mineralization, and induce local neurons to secrete αCGRP. Through the regulation of signaling pathways such as bone morphogenetic protein/Smad (Bmp/Smad), mitogen-activated protein kinase (MAPK), and phosphatidylinositol 3-kinase/protein kinase B (PI3k/Akt), LIPUS promotes the proliferation, migration, and osteogenic differentiation of osteogenic-related cells, thereby enhancing osseointegration of dental implants. Additionally, clinical studies have shown that bone mass increases around the implants after LIPUS treatment, with more pronounced growth observed on the buccal bone plate than on the palatal side. Furthermore, there is a lack of research that systematically summarizes the clinical evidence, in vitro and in vivo studies, and mechanisms of action regarding the role of LIPUS in promoting osseointegration of implants. Therefore, the aim of this study is to discuss the mechanisms of effect of LIPUS on osseointegration of implants, with the goal of further enhancing the outcome of implant-supported prosthodontic treatment.

BACKGROUND:Ca2+expression in astrocytes has been found to be closely related to cognitive function,and the Ca2+signaling pathway regulated by inositol 1,4,5-trisphosphate receptors(IP3R2)and ryanodine receptor(RYR)2 receptors has become a hot spot in the study of cognitive disorder-related diseases. OBJECTIVE:To investigate the expression of Ca2+signals mediated by IP3R2 and RYR2 in hippocampal astrocytes in animal models of delayed encephalopathy after acute carbon monoxide poisoning,and to explore the possible pathogenesis of delayed encephalopathy after acute carbon monoxide poisoning. METHODS:C57BL mice with qualified cognitive function were selected by Morris water maze experiment and randomly divided into control group and experimental group.An animal model of delayed encephalopathy after acute carbon monoxide poisoning was established by static carbon monoxide inhalation in the experimental group,and the same amount of air was inhaled in the control group.Behavioral and neuronal changes,astrocyte specific marker glial fibrillary acidic protein,IP3R2,RYR2 receptor and Ca2+concentration in astrocytes of the two groups were detected using Morris water maze,hematoxylin-eosin staining,western blot,immunofluorescence double labeling and Ca2+fluorescence probe at 21 days after modeling. RESULTS AND CONCLUSION:In the Morris water maze,the escape latency of the experimental group was significantly longer than that of the control group(P<0.05).Hematoxylin-eosin staining results showed that in the experimental group,the number of hippocampal pyramidal cells decreased,the cell structure was disordered,and the nucleus was broken and dissolved.Immunofluorescence results showed that IP3R2 and RYR2 were co-expressed with glial fibrillary acidic protein in the hippocampus,and the expressions of IP3R2,RYR2 and glial fibrillary acidic protein were up-regulated in the hippocampus of the experimental group(P<0.05).Western blot analysis showed that the expressions of IP3R2,RYR2,and glial fibrillary acidic protein in the hippocampus of the experimental group were increased(P<0.05).Ca2+concentration in hippocampal astrocytes increased significantly in the experimental group(P<0.05).To conclude,astrocytes may affect Ca2+signals by mediating IP3R2 and RYR2 receptors,then impair the cognitive function of mice with carbon monoxide poisoning,and eventually lead to delayed encephalopathy after acute carbon monoxide poisoning.

8.Incremental effectiveness of two-dose of mumps-containing vaccine in chidren
Chinese Journal of School Health 2025;46(6):883-887
Objective:
To evaluate the incremental vaccine effectiveness (VE) of two dose of the mumps containing vaccine (MuCV) in chidren, so as to provide a basis for optimizing mumps immunization strategies.
Methods:
A 1∶2 frequency matched case-control study was conducted by using reported mumps cases in childcare centers or schools from Lu an, Hefei, Ma anshan and Huainan cities of Anhui Province from September 1, 2023 to June 30, 2024, as a case group(383 cases). And healthy children in the same classroom were selected as a control group(766 cases). The MuCV immunization histories of participants were collected to estimate the incremental VE of the second dose of MuCV against mumps. Group comparisons were performed using the Chi square test or t-test. For matched case-control pairs, the Cox regression model was employed to calculate the odds ratio (OR) with 95% confidence interval (CI) for two dose MuCV vaccination and to estimate the incremental vaccine effectiveness (VE).
Results:
There were no statistically significant differences between the case and control groups regarding gender, age, dosage of MuCV vaccination and the time interval since the last dose vaccination( χ 2/t=0.05, 0.20, 0.94, -0.02, P >0.05). The proportions of the case and control groups vaccinated with two doses of MuCV were 26.63% and 29.37%, respectively, and the overall incremental VE of the second dose of MuCV was 40.73% (95% CI=3.03%-63.77%, P <0.05). Subgroup analyses revealed that the incremental VE for children with a period of ≥1 year between the two doses of MuCV was 54.13% (95% CI=1.90%-78.56%, P <0.05), while for children with a period of <1 year, it was 30.63% (95% CI=-28.59%-62.58%, P >0.05). The incremental VE of the second dose of MuCV was 30.36% (95% CI=-25.95%-61.50%, P >0.05) in kindergarten children and 66.73% (95% CI=14.92%-86.99%, P <0.05) in elementary and secondary school students. The incremental VE was 28.78% (95% CI=-27.46%-60.21%, P >0.05) within five years of the last dose of MuCV vaccination and 66.07% (95% CI=-41.56%-91.87%, P >0.05) for vaccinations administered beyond five years.
Conclusions
The second dose of MuCV may offer additional protection for children; however, extending the interval between two dose of MuCV (<1 year) has shown limited incremental protective effects. Therefore, it is crucial to consider optimizing current immunization strategies for mumps.

Objective: To investigate the efficacy and safety of intelligent temperature-pressure-controlled flexible ureteroscopy combined with negative-pressure suction sheath lithotripsy in the treatment of upper urinary tract stones ≤2.5 cm. Methods: The clinical data of 225 patients with ≤2.5 cm upper urinary tract stones treated with this surgical method in our department during Aug. 2023 and Jul. 2024 were retrospectively analyzed. The patients were divided into the dual-control group (n=36) and conventional group (n=189) according to whether or not the intelligent temperature and pressure control device was used during operation. In the dual-control group,the intraoperative temperature and pressure in the renal pelvis were monitored and controlled in real time by the temperature and pressure sensors distributed at the end of the ureteral soft lens. The perioperative parameters,stone-removal rate,complication rate and renal function were compared between the two groups. Results: All operations were successfully completed in both groups. The postoperative procalcitonin (PCT) level [(22.75±5.85) ng/L vs. (29.08±6.60) ng/L,P=0.001],difference in the white blood cell (WBC) level [(0.24±2.12)×10
cells/L vs. (1.19±2.17)×10
cells/L,P=0.016],incidence of fever (2.8% vs. 16.9%,P=0.028) and overall complication rate (5.6% vs. 19.6%,P=0.042) were significantly lower in the dual-control group than in the conventional group,while the stone-clearance rate was slightly higher (88.9% vs. 82.5%,P=0.346),with no significant difference. Conclusion: For upper urinary tract stones ≤2.5 cm,intelligent temperature-pressure-controlled ureteroscopy combined with negative-pressure suction sheath lithotripsy has a satisfactory stone-removal rate and a low rate of complications,which is worthy of clinical promotion.

Objective To analyze the economic cost of self-monitoring of gestational diabetes mellitus, and provide a basis for measuring the economic burden of gestational diabetes mellitus, and to provide a reference for the formulation of intervention development and the adjustment of resource allocation. Methods The individual economic cost of self-monitoring for gestational diabetes mellitus was measured based on a decision tree model, and the total economic cost of self-monitoring for gestational diabetes mellitus in Beijing was estimated. The uncertainty of the model parameters was analyzed using one-way sensitivity analysis. Results The average individual economic cost of gestational diabetes self-monitoring was 1184 RMB, and the individual cost incurred by choosing different types of blood glucose meters ranged from 403 to 18 000 RMB. The average individual economic cost of finger-stick blood glucose monitoring was 606 RMB and the average individual economic cost of continuous glucose monitoring was 2 374 RMB. The total economic cost of gestational diabetes self-monitoring in Beijing was 23.818 0 million RMB, and the total economic cost incurred by choosing different types of blood glucose meters ranged from 0.292 5 to 9.027 9 million RMB. The proportion of the finger-stick blood glucose monitoring had the greatest impact on the robustness of the results. Conclusion Finger-stick blood glucose monitoring is still the dominant self-monitoring method and is less costly than continuous glucose monitoring. Self-monitoring of pregnant women with gestational diabetes mellitus incurs certain economic cost and causes an economic burden on society.
