The occurrence of diabetes mellitus (DM) is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver,fat,skeletal muscle,islets, and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response,improving insulin resistance,and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing,heat-clearing, and detoxicating medicinal,which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore,by summarizing the mechanisms between macrophage activation,polarization, and insulin resistance in various tissues,this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio,providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

Colonic mucosal healing is the ultimate goal of ulcerative colitis (UC) treatment, but it remains difficult to realize. Given the higher incidence of UC in males and the beneficial effect of estrogen on UC, we conducted this study to examine the therapeutic potential of estrogen receptor β (ERβ), the primary ER subtype in colon, on mucosal healing in UC. Our study is the first to report that ERβ activation degree was positively correlated with mucosal healing in patients with UC. Furthermore, ERβ activation enhanced mucosal healing in mice with dextran sulfate sodium-induced and biopsy-induced colonic injuries. Mechanistically, ERβ activation promoted autophagy of colonic epithelial cells by inhibiting branched-chain amino acid transport, leading to focal adhesion kinase (FAK) activation. Activated FAK promoted focal adhesion turnover and colonic epithelial cell migration, ultimately facilitating mucosal healing. ERβ -/- colitis mice exhibited impaired mucosal healing compared to wild-type littermates, highlighting the crucial effect of ERβ. Importantly, combination with ERβ-agonist diarylpropionitrile enhanced the amelioration of 5-aminosalicylic acid, a standard UC treatment agent, against mouse colitis. These findings attest to the crucial role of ERβ activation in colonic mucosal healing and may further inform the development of novel strategies for UC treatment.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

The theory of "linkage between spleen and small intestine" has been put forward by doctors as early as the Ming dynasty. In traditional Chinese medicine, the spleen and small intestine cooperate and work together physiologically, and they are also closely related and interact with each other pathologically. The spleen governs transportation and transformation, which involves the function of the small intestine in transforming water and grain. The small intestine, governing the receiving and transformation of substances, depends on the normal transportation of the spleen. At the same time, it provides guarantee for the spleen to transform Qi and generate blood as well as ascend lucidity and descend turbidity. The dysfunction of spleen in transportation is closely related to the dysfunction of small intestine. The stability of intestinal microecology necessitates the normal functioning of the spleen. When the original balance of intestinal flora is disturbed, the spleen functioning will be affected. This study explored the pathogenesis and treatment of diabetes based on the physiological functions of the spleen and small intestine and the Western medicine targets of "nutrients-intestinal flora". According to modern medicine, nutrients are essential to maintain the normal physiological activities of the human body. Proper intake of nutrients can affect the absorption and metabolism of the human body for nutrients by regulating the composition and function of intestinal flora, so as to prevent the occurrence of diabetes. The imbalance of intestinal flora which harbors rich microorganisms may lead to the disturbance of energy metabolism and the dysfunction of the immune system, eventually leading to diabetes. As a metabolic disease, diabetes is closely related to the imbalance of intestinal flora and nutrient intake. Based on the theory of "linkage between spleen and small intestine", this paper discusses the relationship between spleen and small intestine. Furthermore, this paper discusses the correlation between "spleen-small intestine" and "nutrients-intestinal flora" by reviewing the latest progress in modern medicine and clinical research, aiming to provide a theoretical basis and new ideas for the clinical prevention and treatment of type 2 diabetes mellitus.

Objective:To investigate the evaluation efficacy and predictive prognostic value of alpha-fetoprotein (AFP) response in tyrosine kinase inhibitors (TKIs) in combination with PD-1 inhibitors (α-PD-1) for intermediate-to-advanced hepatocellular carcinoma (HCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 205 patients with intermediate-to-advanced HCC who were admitted to 9 medical centers, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from March 2020 to July 2022 were collected. There were 178 males and 27 females, aged (52±12)years. Based on AFP response at 6-8 weeks after treatment, patients were divided into the AFP response group (AFP level decreased by ≥50% compared to baseline) and the AFP no response group (AFP level decreased by <50% compared to baseline). Observation indicators: (1) AFP response evaluation of anti-tumor efficacy; (2) comparison of patient prognosis; (3) analysis of factors affecting patient prognosis. Measurement data with normal distrubution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range) and M( Q1, Q3). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curve and calculate survival rate, and the Log-Rank test was used for survival analysis. The COX proportional risk model was used for univariate analysis and the COX stepwise regression model was used for multivariate analysis. Results:(1) AFP response evaluation of anti-tumor efficacy. Before treatment, all 205 patients were positive of AFP, with a baseline AFP level of 1 560(219,3 400)μg/L. All 205 patients were treated with TKIs in combination with α-PD-1, and the AFP level was 776(66,2 000)μg/L after 6 to 8 weeks of treatment. Of the 205 patients, 88 cases were classified as AFP response and 117 cases were classified as AFP no response. According to the response evaluation criteria in solid tumors version 1.1, the objective response rate (ORR) and disease control rate (DCR) were 42.05%(37/88) and 94.32%(83/88) in patients of the AFP response group and 16.24% (19/117) and 64.10% (75/117) in patients of the AFP no response group, showing significant differences between them ( χ2=16.846, 25.950, P<0.05). According to the modified response evaluation criteria in solid tumors, the ORR and DCR were 69.32% (61/88) and 94.32% (83/88) in patients of the AFP response group and 33.33% (39/117) and 64.10% (75/117) in patients of the AFP no response group, showing significant differences between them ( χ2=26.030, 25.950, P<0.05). (2) Comparison of patient prognosis. All 205 patients were followed up for 12.4(range, 2.4-34.0)months after treatment. The median progression free survival time and total survival time were 5.5 months and 17.8 months, respectively. The 1-year, 2-year progression free survival rates were 20.8% and 7.2%, and the 1-year, 2-year overall survival rates were 68.7% and 31.5%, respectively. The median progression free survival time, 1-year and 2-year progression free survival rates were 9.7 months, 39.6% and 14.2% in patients of the AFP response group and 3.7 months, 7.8% and 2.0% in patients of the AFP no response group, showing a significant difference in progression free survival between them ( χ2=43.154, P<0.05). The median overall survival time, 1-year and 2-year overall survival rates were not reached, 85.2% and 56.3% in patients of the AFP response group and 14.6 months, 56.3% and 14.5% in patients of the AFP no response group, showing a significant difference in overall survival between them ( χ2=33.899, P<0.05). (3) Analysis of factors affecting patient prognosis. Results of multivariate analysis showed that invasion of large blood vessels, extrahepatic metastasis, combined hepatic artery intervention therapy, and AFP response were independent factors influencing progression free survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1 ( hazard ratio=1.474, 1.584, 0.631, 0.367, 95% confidence interval as 1.069-2.033, 1.159-2.167, 0.446-0.893, 0.261-0.516, P<0.05), and Eastern Cooperative Oncology Group score, invasion of large blood vessels, extrahepatic metastasis, and AFP response were independent factors influencing overall survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1 ( hazard ratio= 1.347, 1.914, 1.673, 0.312, 95% confidence interval as 1.041-1.742, 1.293-2.833, 1.141-2.454, 0.197-0.492, P<0.05). Conclusions:AFP response at 6-8 weeks after treatment can effectively evaluate anti-tumor efficacy of TKIs in combination with α-PD-1 for intermediate-to-advanced HCC. AFP response is the independent factor influencing progression free survival and overall survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1.

ObjectiveTo prepare a rat model of heart failure after myocardial infarction by ligation of the anterior descending branch of the left coronary artery, and to observe the effect of Shenfu Yixin granules on the mitochondrial dynamics of rats with heart failure. MethodFifty SD male rats were randomly taken ten as the sham operation group and the rest as modeling group. The rat model of heart failure after myocardial infarction was prepared by ligation of anterior descending branch of left coronary artery. According to the left ventricular ejection fraction(LVEF) on the 28th day after operation, the model rats were randomly divided into the model group, Shenfu Yixin granule low-dose and high-dose groups(3.011, 15.055 g·kg-1) and sacubitril valsartan sodium group(20.83 mg·kg-1). Each administration group was gavaged daily with the corresponding dose of drug solution, while the sham operation group and model group were given the same amount of normal saline once a day for 28 days, with 6 rats in each group. Ultrasound was used to detect the cardiac function parameters, rat heart mass and body mass were weighed to calculate the cardiac mass index, enzyme linked immunosorbent assay(ELISA) was used to detect serum brain natriuretic peptide(BNP) and soluble growth stimulation expressed gene 2 protein(sST2) levels. Hematoxylin-eosin(HE) staining was used to observe the pathological morphology of the myocardium. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to detect the mRNA and protein expression of mitochondrial fusion protein 1/2(Mfn1/2), optic atrophy protein 1(Opa1), dynamin-related protein 1(Drp1) and fission protein 1(Fis1). ResultCompared with the sham operation group, the mRNA and protein expression of LVEF, Mfn1, Mfn2, Opal in the model group decreased(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels increased(P<0.05). Compared with the model group, the expression of LVEF, Mfn1, Mfn2, Opal mRNA and protein increased in Shenfu Yixin granule high-dose and sacubitril valsartan sodium groups(P<0.05), while BNP, sST2, cardiac mass index, Drp1, Fis1 mRNA and protein levels decreased(P<0.05). Pathological observation showed that compared with the sham operation group, the model group had disordered arrangement of myocardial cells, inflammatory cell infiltration and myocardial fibrosis. Compared with the model group, the degree of inflammatory cell infiltration, myocardial or interstitial fibrosis was improved and alleviated in all administered groups. ConclusionShenfu Yixin granules can resist heart failure, reduce cardiac mass index, decrease BNP and sST2 contents, and improve cardiac function. Its mechanism may be related to the adjustment of mitochondrial dynamics.
