Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

This article presents a case of acute ST-segment elevation myocardial infarction (STEMI) in a pregnant woman caused by coronary artery dissection. The 41-year-old patient had undergone cardiac valve surgery at the age of 1 and had no risk factors such as hypertension, diabetes, smoking, alcohol use, or a family history of coronary artery disease. At 31 +1 weeks of gestation, she experienced sudden chest pain for 4 hours and was emergently referred to Peking University First Hospital on June 1, 2021. Electrocardiogram revealed ST-segment elevation in leads I, aVL, and V 2 to V 6. Biochemical assays showed elevated levels of high-sensitivity cardiac troponin I and creatine kinase-MB. Echocardiography indicated segmental ventricular wall motion abnormalities (apical) and reduced left ventricular function, confirming the diagnosis of acute anterior wall STEMI. The patient promptly underwent emergency coronary angiography and percutaneous coronary intervention and confirmed coronary artery dissection. Postoperative care included antiplatelet, anticoagulation, and supportive treatment. At 34 +3 weeks of gestation, with the condition of acute anterior wall STEMI being relatively stable, a cesarean section was successfully performed. Regular cardiology follow-ups were scheduled postpartum, and cardiac function was normal in two years after discharge.

Objective To explore the effect of Morinda citrifolia juice(MCJ)combined with ethylene diamine tet-raacetic acid(EDTA)on premolar bonding strength and nanoleakage and compare the results with those of the most commonly used root canal irrigation solution,sodium hypochlorite(NaClO),to provide a reference for clinical applica-tion.Methods This study was approved by the ethics review committee.Sixty-three human premolars extracted for orthodontic treatment were randomly divided into a control group(distilled water group)and 6 experimental groups ac-cording to the different rinsing solutions used after the surface enamel was removed.The experimental groups included Group A(2.5%NaClO),Group B(5.25%NaClO),Group C(6%MCJ),Group D(2.5%NaClO-17%EDTA),Group E(5.25%NaClO-17%EDTA),and Group F(6%MCJ-17%EDTA)(n = 9).After soaking in the corresponding rinsing so-lution for 20 minutes,they were layered and stacked on their surfaces to form 4 mm×4 mm×3 mm Z350 resin blocks.Six samples from each group were cut into 1 mm×1 mm×8 mm specimen strips for microtensile bonding strength test-ing.The fracture type was determined under a stereomicroscope,and the remaining 3 samples from each group were aged and cut into 1 mm thick slices for interface nanoleakage testing and scanning electron microscopy observation of the resin dentin bonding interface.Results There were significant differences in the microtensile bonding strength among the groups(P＜0.05),and the control group had the highest bonding strength.Among experimental groups,Group B had the lowest bonding strength,mainly bonding interface fracture,and Group F had the highest bonding strength,mainly mixed fracture.There were significant differences in nanoleakage among all groups(P＜0.05),and the control group had the lowest nanoleakage value.Among experimental groups,Group B had the highest nanoleakage,with resin protrusions being unaltered,and Group F had the lowest nanoleakage value,with resin protrusions being thick and dense.Conclusion The higher the concentration of NaClO was,the worse the bonding strength and edge sealing of the crown dentin were.The effects of root canal irrigation with MCJ and EDTA on the adhesive strength and edge sealing of crown dentin were less pronounced than those of root canal irrigation with NaClO and EDTA.

Objective To investigate the diagnostic value of detachable string magnetically controlled capsule endoscopy(ds-MCE)in patients with liver cirrhosis.Methods Patients with liver cirrhosis were screened for esophagogastroduodenoscopy(EGD)and ds-MCE examination to assess the accuracy of ds-MCE in identifying gastroesophageal varices,high-risk esophageal varices and portal hypertensive gastropathy using EGD as the gold standard,and evaluate the detection of portal hypertensive enteropathy and the comfort level of patients.Results From May 2021 to July 2022,a total of 53 patients with liver cirrhosis were successfully enrolled.With EGD as the gold standard,ds-MCE detected esophageal varices with 95.45％for sensitivity,100％for specificity and adjusted positive predictive value(PPV),95.65％for adjusted negative predictive value(NPV),and 0.877 for Kappa value(P＜0.001).For detection of gastric varices,ds-MCE had sensitivity,specificity,adjusted PPV,and adjusted NPV of 93.94％,90％,90.38％and 93.69％,and Kappa value of 0.839(P＜0.001).For detection of portal hypertension gastropathy,ds-MCE had sensitivity,specificity,adjusted PPV and adjusted NPV of 80％,90.70％,89.59％and 81.93％,and Kappa value of 0.657(P＜0.001).In differentiating high-risk esophageal varices,the sensitivity,specificity,adjusted PPV,and adjusted NPV were 76％,100％,100％and 77.43％,respectively;Kappa value was 0.770(P＜0.001).Of the patients with liver cirrhosis,26.0％(13/50)were diagnosed with portal hypertensive enteropathy.The main mucosal changes were edema,erythema,and vascular dysplasia.The ds-MCE comfort score of 3(2,4)was higher than that of the traditional EGD 1(0,3)(P＜0.000 1).Conclusion Compared with EGD,ds-MCE is an accurate,safe,feasible and comfortable method for detecting esophagogastric varices and portal hypertensive gastropathy in patients with liver cirrhosis.It is a potential alternative to EGD screening surveillance of gastroesophageal varices in patients with liver cirrhosis.

Objective To study the effect of Ditan Decoction combined with aripiprazole and olanzapine in the treatment of schizophrenia and its influence on serum inflammatory factors chnage.Methods Seventy-seven patients with schizophrenia meeting the requirements visiting the outpatient department and hospitalized in Dazu District Hospital of Traditional Chinese Medicine and Dazu District Mental Health Center from July 2021 to March 2023 were selected as the study subjects and divided into the observation group(n=38)and control group(n=39).The control group was treated with aripiprazole and olanzapine,and the observation group was combined with Ditan Decoction on the basis of the control group.After 8 weeks of treatment,the TCM syndrome scores,Positive and Negative Syndrome Scale(PANSS)score,serum inflammatory factors(IL-6,IL-1β,IL-17)levels were compared between the two groups.Results The total effective rate was 97.37％in the observation group and 84.65％in the control group,and the difference was statistically signifi-cant(P＜0.05).The TCM syndrome score of each item and total scores after treatment in the observation group were lower than those in the control group(P＜0.05),the PANSS positive symptoms,negative symp-toms,general psychopathology and total scores in the observation group were lower than those in the control group(P＜0.05).The IL-17,IL-6 and IL-1β levels after treatment in observation group were lower than those in the control group(P＜0.05).Conclusion Ditan Decoction combined with aripiprazole and olanzapine has significant clinical efficacy in the treatment of schizophrenia,which could further reduce the symptom score of the patients and improve the serum inflammatory factors levels.The treatment is highly safe and worthy of clinical recommendation.

Rheumatoid arthritis(RA)is an autoimmune disease characterized by chronic synovial in-flammation.Moxibustion treatment can significantly improve RA immune disorders and reduce synovial in-flammation,but its mechanism of action needs to be further deepened.Senescence is a key factor that induces the occurrence and development of RA,and macrophages,as the key sentinel sites of the immune system to monitor aging,play an important role in the onset process of RA.The circadian clock dominates the circadian rhythm of the body,regulates the expression of a variety of proteins and cell functions,and is widely involved in the physiological and pathological processes of a variety of diseases.The circadian clock is involved in mac-rophage senescence and has the effect of regulating immune disorders.Among the mechanisms affecting the occurrence and development of RA,macrophage senescence has received more and more attentions as an im-portant breakthrough point.Therefore,this article mainly elucidates the possible pathogenesis of RA from the perspective of the involvement of the biological clock in macrophage senescence and analyzes the feasibility of moxi-bustion in the treatment of RA by regulating the biological clock and participating in macrophage senescence.

Objective:To clarify whether CLDN5 is involved in the pathogenesis of sensitive skin (SS) through inflammation.Methods:From January 2018 to March 2020, in the Dermatology Laboratory of the First Affiliated Hospital of Kunming Medical University, facial tissues were collected from 5 patients diagnosed with sensitive skin and 5 cases of normal facial skin. The organizational experiment was divided into two groups: SS group and normal skin (NS) group. The cell experiment was divided into two groups: sh-CLDN5 group in which CLDN5 was knocked down and sh-NC group with normal expression of CLDN5. After paraffin embedding and sectioning, immunohistochemical staining was performed to determine the expression of claudin-5 in sensitive skin and normal skin. In cell experiments, lentivirus shRNA was transfected into HaCaT cells. Three cases in sh-CLDN5 group and three cases in sh-NC group were collected for transcriptome sequencing, and differentially expressed pro-inflammatory factor mRNA was screened from the sequencing results. Western blot or ELISA was used to verify the protein level expression of differentially expressed pro-inflammatory cytokines mRNA in HaCaT cells, and Western blot was used to detect the expression of key proteins in MAPK pathway and NF-κB in the sh-CLDN5 group and sh-NC group.Results:Immunohistochemical staining showed that claudin-5 was localized in the interstitial cells of the normal skin granular layer. Patients with sensitive skin had thinner epidermis than normal skin and significantly reduced claudin-5 expression. In HaCaT cells, the expression of pro-inflammatory cytokine IL-23A was increased, and IL-8 was elevated in the sh-CLDN5 group [(272.91±30.25) pg/ml, n=3] compared with sh-NC group [(55.58±7.07) pg/ml, n=3] ( P<0.01). There was no statistically significant difference in secretion volume between sh-NC group [(8.04±1.34) pg/ml, n=3] and sh-CLDN5 group [(12.15±3.07) pg/ml, n=3]. The expression of P-JNK, p-ERK, and P-p38 in the MAPK pathway was significantly increased ( P<0.01). Conclusions:CLDN5 is an important gene involved in the pathogenesis of SS. CLDN5 upregulates IL-23A and IL-8 in HaCaT and activates the MAPK pathway, which is involved in the process of early SS inflammation.
