Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

Chronic gastritis is a chronic inflammation of the gastric mucosa caused by various etiologies and can be categorized into chronic non-atrophic gastritis and chronic atrophic gastritis.Chronic atrophic gastritis is a common disorder of the digestive system characterized by gastric mucosal gland atrophy,mucosal thinning,and basal layer thickening.The development of intestinal metaplasia and atypical hyperplasia on this basis is recognized as a precancerous lesion of gastric cancer and represents a key stage in the"inflammation-cancer transformation"of chronic gastritis.However,universally recognized and effective treatment strategies for this"inflammation-cancer transformation"process are lacking in clinical practice.This study integrates Correa′s cascade reaction with clinical practice,summarizing the pathogenesis of the"inflammation-cancer transformation"of chronic gastritis as weakness of the middle jiao and blood stasis.It suggests that the"inflammation-cancer transformation"process involves the pathological development of spleen and stomach deficiency,transportation and transformation dysfunction,turbid phlegm,blood stasis,and the gradual formation of cancerous toxins,with spleen and stomach weakness as the core mechanism and phlegm and blood stasis as the crucial pathological link.Based on an in-depth exploration of the deficiency of the middle jiao and blood stasis,supported by pharmacological research and clinical experience,this paper proposes the therapeutic approach of strengthening the spleen and replenishing qi,expelling phlegm and activating blood.It discusses the related prescriptions in preventing and treating the"inflammation-cancer transformation"of chronic gastritis.This study aims to provide new perspectives and insights for the prevention and treatment of chronic gastritis with traditional Chinese medicine,offering a novel framework for clinical treatment.

OBJECTIVE: To investigate the short-term effectiveness of uni-portal non-coaxial spinal endoscopic surgery (UNSES) via crossing midline approach (CMA) in the treatment of free lumbar disc herniation (FLDH). METHODS: Between March 2024 and June 2024, 16 patients with FLDH were admitted and treated with UNSES via CMA. There were 9 males and 7 females with an average age of 55.1 years (range, 47-62 years). The disease duration was 8-30 months (mean, 15.6 months). The pathological segments was L _{3, 4} in 4 cases, L _{4, 5} in 5 cases, and L ₅, S ₁ in 7 cases. The preoperative pain visual analogue scale (VAS) score was 6.9±0.9 and the Oswestry disability index (ODI) was 57.22%±4.16%. The operation time, intraoperative bleeding volume, postoperative hospital stay, and incidence of complications were recorded. The spinal pain and functional status were evaluated by VAS score and ODI, and effectiveness was evaluated according to the modified MacNab criteria. CT and MRI were used to evaluate the effect of nerve decompression. RESULTS: All 16 patients underwent operation successfully without any complications. The operation time was 63-81 minutes (mean, 71.0 minutes). The intraoperative bleeding volume was 47.3-59.0 mL (mean, 55.0 mL). The length of hospital stay after operation was 3-4 days (mean, 3.5 days). All patients were followed up 1-3 months, with 15 cases followed up for 2 months and 14 cases for 3 months. The VAS score and ODI gradually decreased over time after operation, and there were significant differences between different time points ( P<0.05). At 3 months after operation, the effectiveness was rated as excellent in 12 cases and good in 2 cases according to the modified MacNab criteria, with an excellent and good rate of 100%. CT and MRI during follow-up showed a significant increase in the diameter and cross-sectional area of the spinal canal, indicating effective decompression of the canal. CONCLUSION When using UNSES to treat FLDH, choosing CMA for nerve decompression has the advantages of wide decompression range, large operating space, and freedom of operation. It can maximize the preservation of the articular process, avoid fracture and breakage of the isthmus, clearly display the exiting and traversing nerve root, and achieve good short-term effectiveness.

In order to improve the effectiveness of private class inquiry with the development of information teaching, the smart teaching platform has been established, with instructional management, curriculum setting, teacher preparation, classroom application, supervision and monitoring modules. Taking the platform as the medium, the small class inquiry learning community of entity curriculum is constructed between students and the teachers. In the eight-year medical teaching, the content of learning cycle is designed according to the entity curriculum, which is issued on cloud platform before class, in class and after class. Students learn basic concepts by themselves in the learning community, explore the application of knowledge under the guidance of teachers, and expand knowledge in class or after class. After having test in teaching procedure, the small class learning community based on smart teaching cloud platform has a submission rate, interaction rate and score rate of more than 90%. It can not only make full use of the advantages of information-based teaching resources, but also build face-to-face learning community in the course teaching, reflecting the emotional interaction of personalized teaching. It's suggested that new approaches to teaching should be student-centered and activity-based, engaging students actively in the learning process, which can promote students' autonomous learning ability and innovative thinking ability.

Objective:To explore any effect of transcranial direct current stimulation (tDCS) on neurons, behavior, cerebral blood flow (CBF), vascular regeneration, and the expression of vascular endothelial growth factor (VEGF) and CD34 protein in rats modeling cerebral infarction.Methods:Thirty-two adult male Sprague-Dawley rats were randomly divided into a sham surgery group (Sham group), a model group (modeled with middle cerebral artery occlusion, MCAO group), an anode transcranial direct current stimulation group (A-tDCS group), and a cathode transcranial direct current stimulation group (C-tDCS group), each of 8. MCAO models were established in the rats of the MCAO, A-tDCS and C-tDCS groups using thread fixation. Twenty-four hours after successful modeling, both the Sham and MCAO groups were connected with electrodes without current stimulation, while the A-tDCS and C-tDCS groups were given 20 minutes of 200μA anodic or cathodic electrical stimulation daily, 5 days a week for 12 days. Before and 24 hours after the modeling, and then after the 12 days of treatment, the four groups received Longa neurobehavioral scoring. Moreover, three days after the modeling as well as after the 12 days of treatment, changes in CBF were observed using MRI. Any blood vessel regeneration was observed using immunofluorescence methods, and the expression of VEGF and CD34 proteins were detected using western blotting.Results:The rats in the MCAO, A-tDCS and C-tDCS groups exhibited various degrees of neurological deficit after the modeling. After the 12 days of treatment the average neurobehavioral scores of the A-tDCS and C-tDCS groups were significantly lower than that of the MCAO group, with the A-tDCS group′s average significantly lower than that of the C-tDCS group. Three days after the modeling, 3D-arterial spin labeling scanning showed a significant decrease in CBF around the ischemic lesion in the MCAO, A-tDCS and C-tDCS groups, but that had increased to varying degrees after 12 days of treatment. The changes in the A-tDCS and C-tDCS groups were significantly larger than in the MCAO group on average, with the former group improving significantly more than the latter. After the 12 days of treatment, new vascularization and the expression of VEGF and CD34 proteins were significantly higher in the A-tDCS and C-tDCS groups than in the MCAO group, with the change in the former group again significantly greater than in the latter.Conclusions:tDCS can relieve the symptoms of neurological deficits in rats with cerebral infarction, promote vascular regeneration, CBF, and expression of VEGF and CD34 proteins. Anodic is superior to cathodic stimulation.

Precancerous lesions of gastric cancer (PLGC) is a pathological change accompanied by intestinal metaplasia and dysplasia on the basis of chronic atrophic gastritis. It is also an important stage of "inflammation-cancer transformation" on gastric mucosa. Paying attention to the intervention of PLGC has important value and significance for the secondary prevention of gastric cancer. PLGC has the characteristics of occult onset, toxin damaging collaterals, and long course of disease, which is highly consistent to the pathogenesis characteristics of incubative pathogenic factors. Based on the relevance of incubative pathogenic factors and PLGC, treatment of PLGC from the perspective of incubative pathogenic factors should be mainly strengthening the spleen and stomach, and combined with the methods of regulating qi and dissipating dampness, and removing blood stasis and detoxification. It should also pay attention to the prognosis.Paying attention to the body-mind treatment can reduce the re-occurrence , so as to provide a new way of thinking for treating PLGC from incubative pathogenic factors.
