Objective To investigate the significance of early diagnosis and intervention in cases with severe hand-foot-mouth disease. Methods Nine severe cases were chosen from 220 hospitalized children with hand-foot-mouth disease for retrospective analysis, including onset, disease progression, the blood and cerebrospinal fluid tests, electroencephalogram data, patients' treatment responses and prognosis. Pearson X2 test and t test were utilized for statistical analysis. Results All cases showed nervous systems involved symptom, including meningeal irritation sign and (or) other pathological signs of nervous system (9 cases), drowsy (7 cases), trembling (6 cases), voiding dysfunction (3 cases), hypersensitivity(3 cases), autonomic nervous system disorders (2 cases), ataxia (1 case), left leg mild paralysis (1 case) and early stage of pulmonary edema (1 case). Early intervention, such as high dose gamma globulin, methylprednisolone, mannitol treatment restriction of fluid input, started before the development of heart and lung failure. No case died but one patient with encephalomyelitis showed hobbling left leg, which didn't recover until 6 weeks later. One case with brainstem encephalitis still showed abnormal electroencephalogram after 8 weeks follow-up but without clinical symptom. Conclusions Enterovirus 71 can cause severe hand-foot-mouth disease complicated by encephalitis, meningitis and pulmonary edema. Early active intervention before the development of neurogenic pulmonary edema can improve the prognosis and reduce the mortality.

Reflux esophagitis （liver-stomach disharmony， Spittoon-Qi interties， Qi and blood stasis syndrome， turbid poison intrinsic） and nonalcoholic fatty liver disease （liver depression， spleen deficiency， phlegm and blood stasis syndrome， hot and humid embodiment， phlegmy wet resistance） and functional dyspepsia （liver depression syndrome， liver stomach with spleen deficient， spleen deficiency cold syndrome， in a word， fever） is a common disease and frequently encountered disease of digestive system. The course of disease is prolonged and the prevalence is high. The successful establishment of animal model combining disease and syndrome is the premise of exploring the mechanism of traditional Chinese medicine（TCM） effect and the foundation of the development of new preparations. At the same time， mastering the complex relationship network among disease， syndrome and prescription is the prerequisite of effective treatment. When the same syndrome occurs between different diseases， the concept of "treating different diseases with the same treatment" in TCM suggests that methods can be cross-referenced for the shortage of some syndrome models. TCM intervention of digestive diseases has the characteristics of multi-path， multi-target， multi-dimension and multi-level. Therefore， this article through the literature review， summarizes the reflux esophagitis， nonalcoholic fatty liver disease and functional dyspepsia is a common disease such as the combined operation method of the model and the intervention mechanism of TCM， so as to diseases of the digestive system of different syndrome types provides the theory basis for the objective of research， and the basic research of TCM prescription and achievements provide methodological guidance.

ObjectiveTo explore the possible mechanism of Pingwei Capsules （平胃胶囊） for chronic atrophic gastritis from rapidly accelerated fibrosarcoma / mitogen-activated protein kinase /extracellular-signal-regulated kinase （Raf/MEK/ERK） pathway that influences the activation of fibrosarcoma protein/mitogen. MethodsFifteen SD rats were randomly divided into 5 rats in the blank group and 10 rats in Pingwei Capsules group. The rats in the blank group were given 1 ml/100 g of saline by gavage， and the rats in Pingwei Capsules group were given 0.63 g/（kg·d） of Pingwei Capsule suspension by gavage， and serum was collected for 3 consecutive days. N-methyl-N'-nitro-N-nitrosoguanidine （MNNG） was used to induce human gastric mucosal epithelial cells GES-1 to establish a precancerous lesion cell model. The successful cells were divided into control group （10% fetal bovine serum）， blank serum group （10% fetal bovine serum plus 10% blank serum）， and medication-containing serum group （serum with medication of Pingwei Capsule）， and the volume fraction and time of intervention of Pingwei Capsule-containing serum were screened by CCK-8 assay. Human gastric mucosal epithelial cells GES-1 were divided into normal group， model group， blank serum group， medication-containing serum group， U0126 group， and combined group， with 6 replicate wells in each group. After successful modelling of the cells in all groups except the blank group， an equal volume of fetal bovine serum was added to the normal and model groups， an equal volume of blank serum was added to the blank serum group， a screening volume fraction of Pingwei Capsule-containing serum was added to Pingwei Capsule group， a 10 μmol/L mitogen-activated extracellular signal regulated kinase 1 （MEK1） inhibitor U0126 was administered in the U0126 group， an equal dose of Pingwei Capsule-containing serum plus 10 μmol/L of U0126 was administered to the combined group. After the selected incubation time， the level of interleukin 6 （IL-6） was detected in the cells by ELISA， the expression of IL-6 and MEK1 was detected by immunofluorescence， and the expression of IL-6， Raf， MEK1， and ERK mRNA was detected by RT-qPCR， and the expression of IL-6， Raf， MEK1， and ERK mRNA in the cells was detected by Western blot. ResultsThe 5.35% volume fraction， 48 h intervention of Pingwei Capsule-containing serum was selected for subsequent experiments. Compared with the normal group， the IL-6 content in cell supernatants and the expression of IL-6， Raf， MEK1， ERK mRNA and ERK1/2 proteins in cells increased in the model group and blank serum group （P＜0.01）. Compared with the model group， all of the above indexes were improved in medication-containing serum group， U0126 group， and combined group （P＜0.05 or P＜0.01）. Compared with medication-containing serum group， the expression of IL-6， MEK1 expression， the expression of IL-6， Raf， MEK1 and ERK mRNA， and the expression of IL-6， Raf， MEK1 and ERK1/2 proteins reduced in the cells of combined group （P＜0.05 or P＜0.01）. Compared with the U0126 group， IL-6 expression reduced and IL-6， MEK1 and ERK1/2 protein expression reduced in cells of combined group （P＜0.05 or P＜0.01）. ConclusionThe Pingwei Capsule-containing serum may play a role in the treatment of chronic atrophic gastritis by improving the inflammation-cancer transformation of GES-1 cells through inhibiting the Raf/MEK/ERK pathway.

To systematically review randomized controlled trials （RCTs） of traditional Chinese medicine （TCM） intervention in ulcerative colitis （UC）， and analyze the characteristics of these studies and their outcome indicators， thereby providing references for the design of future RCTs of TCM intervention in UC and offering evidence supporting the clinical application of TCM in UC. A computerized search was conducted in the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， SinoMed， PubMed， Cochrane Library， EMbase， and Web of Science databases for RCTs of TCM intervention in UC published from January 2021 to August 2024. The risk of bias was assessed， and outcome indicators were qualitatively analyzed. A total of 555 RCTs were included， with a sample size of 44 853 participants. The largest sample size was 218 cases， and the smallest was 28 cases， with most studies focusing on 60-100 participants. Of the 386 RCTs that explicitly reported TCM syndrome types， the top three were large intestine dampness-heat syndrome （31.05%）， spleen and kidney yang deficiency syndrome （12.47%）， and spleen deficiency with dampness syndrome （9.17%）. The interventions， ranked by frequency of use， included internal Chinese medicine compounds/preparations （64.5%）， Chinese medicine compounds/preparations with retained enema （18.2%）， internal Chinese medicine compounds/preparations + external TCM treatment （5.95%）， and external TCM treatment alone （4.86%）. The treatment duration was mainly 4-8 weeks （64.86%）， with 61 studies （10.99%） reporting follow-up time. A total of 157 outcome indicators were used， with a frequency of 3 460 occurrences， classified into six domains： TCM syndromes and symptoms （346 occurrences， 10%）， symptoms/signs （541 occurrences， 15.64%）， physical and chemical examinations （2 119 occurrences， 61.24%）， quality of life （107 occurrences， 3.09%）， long-term prognosis （61 occurrences， 1.76%）， and safety events （284 occurrences， 8.21%）. The analysis reveals several limitations in the outcome indicators of TCM intervention in UC， including the lack of a basis for sample size calculation， non-standardized TCM syndrome classification， absence of trial design and registration， inadequate blinding and allocation concealment， adherence issues with interventions， imbalanced selection of surrogate and endpoint indicators， inconsistency in the timing of outcome measurements， design issues that require standardization， and ethical and safety concerns. It is recommended that future studies actively construct a set of core indicators for UC that include standardized TCM syndrome classification， clear efficacy evaluation indicators， key endpoint indicators， and reasonable measurement time points. Long-term prognostic impacts， comprehensive assessments of patients' quality of life， and consideration of economic benefits should be emphasized， providing a basis for the clinical practice of TCM in the treatment of UC.
