Oral diseases concern almost every individual and are a serious health risk to the popula-tion.The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour.Based on the principle of"learning from the nature",Deng Xu-liang's group of Peking University School and Hospital of Stomatology has proposed a new concept of"microstructural biomimetic design and tissue adaptation of tooth/jaw materials"to address the worldwide problems of difficulty in treating dentine hypersensitivity,poor prognosis of restoration of tooth defects,and vertical bone augmentation of alveolar bone after tooth loss.The group has broken through the bottle-neck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects,and invented key technologies such as crystalline/amorphous multi-level assembly,ion-transportation blocking,and multi-physical properties of the micro-environment reconstruction,etc.The group also pioneered the cationic-hydrogel desensitizer,digital stump and core integrated restora-tions,and developed new crown and bridge restorative materials,gradient functionalisation guided tissue regeneration membrane,and electrically responsive alveolar bone augmentation restorative membranes,etc.These products have established new clinical strategies for tooth/jaw defect repair and achieved inno-vative results.In conclusion,the research results of our group have strongly supported the theoretical im-provement of stomatology,developed the technical system of oral hard tissue restoration,innovated the clinical treatment strategy,and led the progress of the stomatology industry.

Objective To explore the clinical effect of Buqi Huayu prescription on chronic atrophic gastritis with intestinal metaplasia.Methods A total of 60 patients with chronic atrophic gastritis and intestinal metaplasia in the Department of Spleen and Stomach Diseases,Jinhua Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from April 2019 to June 2020 were selected and randomly divided into Buqi Huayu prescription group and control group,with 30 cases in each group.Patients in Buqi Huayu prescription group were treated with Buqi Huayu prescription;Patients in control group were treated with folic acid tablets.After 6 months of treatment,the clinical comprehensive efficacy,traditional Chinese Medicine syndrome score,pathological change score,serum pepsinogen(PG)Ⅰ,PGⅡ,PGⅠ/PGⅡ(PGR)were observed before and after treatment in two groups.Results The clinical curative effect of Buqi Huayu prescription group was significantly better than that of control group(90%vs.70%,P<0.05).After treatment,traditional Chinese Medicine syndrome score and gastric mucosa pathology score of two groups were lower than before treatment(P<0.05).The intestinal metaplasia score of Buqi Huayu prescription group was significantly higher than that of control group(P<0.05).The levels of PGⅠ and PGR were higher than before treatment,while the levels of PGⅡ were lower than before treatment(P<0.05).All the indexes in Buqi Huayu prescription group were better than those in control group(P<0.05).Conclusion Buqi Huayu prescription is effective in the treatment of chronic atrophic gastritis with intestinal metaplasia.It can not only improve the pathological changes of patients,but also increase the level of serum PGⅠ and PGR,and decrease the level of PGⅡ.

In western medicine， the small intestine anatomically belongs to the digestive system and is also an important immune organ of the body. The innate immune system of the small intestine consists of a tissue barrier， innate immune cells， and innate immune molecules. The dysfunction of any part can cause metabolic disorders and eventually lead to diabetes. In the pathogenesis of diabetes， traditional Chinese medicine （TCM） has the theory of ''spleen deficiency causing diabetes''， which points out that the impaired spleen function results in inadequate transformation， impaired essence spread， and turbidity by essence accumulation， which is the core pathological link of blood glucose metabolism disorder in diabetes. In terms of the relationship between the small intestine and the spleen， the theory of TCM holds that the small intestine is located in the abdomen and the abdomen is dominated by the spleen. The digestion， absorption， and endocrine functions of the small intestine are also similar to the functions of spleen in governing movement and transformation and spreading essence by virtue of spleen Qi. Therefore， the anatomical and physiological functions of the small intestine in western medicine are closely related to the spleen in TCM. At the same time， the spleen is closely related to the innate immune function of the small intestine in TCM. The spleen participates in the generation and distribution of defense Qi， and the process of defense Qi playing the external function is similar to the process of the activation of the innate immune response. The spleen is also an important organ involved in fluid metabolism， which can cooperate with the lung and kidney to timely remove turbid fluid from the body. It can also work with the stomach as the hub of Qi ascending and descending and regulate the physiological activities of "clear Yang" and "turbid Yin"， so as to ensure the homeostasis of the internal environment of the body， which is the basis for maintaining the normal function of the innate immunity of the small intestine. Therefore， taking "spleen deficiency causing diabetes" as a bridge， the theory of TCM and western medicine were combined to explain the relationship between small intestinal innate immunity imbalance and the pathogenesis of diabetes from the perspective of TCM， which is helpful to understand the pathogenesis of diabetes in a deeper level and also provide a new perspective and new way for the prevention and treatment of this disease with TCM.

In order to establish a rapid,specific and sensitive detection method for Streptococcus equi subspecies zooepidemicus(SEZ)and to understand the infection status of SEZ in horses ente-ring China,specific primers were designed and synthesized based on the conserved gene comB of standard strain SEZ(ATCC 43079)in this work.Then,the pMD19-T-comB recombinant plasmid was constructed and used as a standard positive template.After that,the fluorescence-based quantitative PCR(qPCR)detection method based on SYBR Green Ⅰ dye was established.Totally,477 equine entry serum samples from 6 countries,including Netherlands,Belgium,Japan,Germa-ny,Argentina and New Zealand,during 2018 to 2023,were randomly selected and detected for SEZ by the qPCR method.Results showed that the established qPCR method had specific amplification for only SEZ,which illustrated a good specificity.Sensitivity test of the method showed that the limited detection amount was 4.58 X101 copies/μL.And the repeatability test showed that the coef-ficient of variation of intra-batch repeatability was less than 0.5％,while the inter-batch repeat-ability was less than 3.0％,which indicated good repeatability and high stability.Retrospective a-nalysis showed that totally 11 of 477 positive samples were detected,with a relatively low positive rate of 2.31％(11/477).Among them,all the 40 samples from Netherlands in 2018 were negative(0/40).In the samples of 2019,one positive was detected from Belgium(1/20),while all other 36 samples which form Japan and Germany were negative.In the samples of 2021,three samples(3/34)from Japan and one sample(1/20)from Argentina were positive,and all the other 40 samples from the Netherlands were negative.In the samples of 2022,76 samples from Netherlands were all negative.While in the 2023,5(5/126)of 126 samples from Netherlands and one(1/88)of 88 from New Zealand were found positive with SEZ.To summarize,The SYBR Green Ⅰ qPCR method for the diagnosis of SEZ was successfully established,and it could provide necessary technical support for the rapid quarantine of China's entry-exit and port departments,as well as the epidemiological investigation of the disease.

Adipose progenitor cells(APCs) represent a prominent stromal cellular component of adipose tissue and are now identified as highly heterogenous populations. However, the role of APCs in regulating systemic metabolism remains unknown. Using single cell RNA-sequencing, we investigated the role of the APC subpopulations in regulating development of type 2 diabetes. CD9 + CD55 low APCs are the novel subset identified in this study, which is significantly increased in type 2 diabetic patients. Transplantation of these cells from type 2 diabetic patients into adipose tissue caused glycemic disturbance in mice. Depletion of pathogenic APCs improved obesity-related glycemic disturbance. Collectively, our data provide deeper insights into human APC functionality and highlights APCs as a potential therapeutic target to combat type 2 diabetes. This study has been published in Nature Communications, 2024, 15(1): 4827.

INTRODUCTION: We aimed to compare the early clinical manifestations, laboratory results and chest computed tomography (CT) images of COVID-19 patients with those of other community-acquired pneumonia (CAP) patients to differentiate CAP from COVID-19 before reverse transcription-polymerase chain reaction results are obtained. METHODS: The clinical and laboratory data and chest CT images of 51 patients were assessed in a fever observation ward for evidence of COVID-19 between January and February 2020. RESULTS: 24 patients had laboratory-confirmed COVID-19, whereas 27 individuals had negative results. No statistical difference in clinical features was found between COVID-19 and CAP patients, except for diarrhoea. There was a significant difference in lymphocyte and eosinophil counts between COVID-19 and CAP patients. In total, 22 (91.67%) COVID-19 patients had bilateral involvement and multiple lesions according to their lung CT images; the left lower lobe (87.50%) and right lower lobe (95.83%) were affected most often, and all lesions were located in the peripheral zones of the lung. The most common CT feature of COVID-19 was ground-glass opacity, found in 95.83% of patients, compared to 66.67% of CAP patients. CONCLUSION Diarrhoea, lymphocyte counts, eosinophil counts and CT findings (e.g. ground-glass opacity) could help to distinguish COVID-19 from CAP at an early stage of infection, based on findings from our fever observation ward.

Objective:To investigate the clinical efficacy of laparoscopic sleeve gastrectomy in obese adolescents.Methods:The retrospective and descriptive study was conducted. The clinical data of 37 obese adolescents who were admitted to Drum Tower Hospital Affiliated to Nanjing University Medical School between July 2016 and August 2020 were collected. There were 18 males and 19 females, aged 18(range, 13?19)years. All patients underwent laparoscopic sleeve gastrec-tomy. Observation indicators: (1) surgical and postoperative situations; (2) follow-up. The patients were followed up by outpatient review to detect body weight, blood glucose, blood lipid, blood pressure, nutrition situation and related complications at 3, 6 and 12 months after operation. The follow-up was up to August 2021. Measurement data with normal distribution were represented as Mean± SD. Repeated measurement data were analyzed by Repeated Measures Anova. Measurement data with skewed distribution were represented by M(range). Count data were expressed as absolute numbers or percentages. Results:(1) Surgical and postoperative situations. All 37 patients under-went laparoscopic sleeve gastrectomy successfully, the operative time was (50±7)minutes, the volume of intraoperative blood loss was (53±17)mL, and the duration of postoperative hospital stay was (3.0±0.5)days. Of the 37 patients, 2 cases had puncture infection. There was no complication such as bleeding occurred. (2) Follow-up. Of the 37 patients, 35, 31 and 22 cases were followed up at postoperative 3, 6 and 12 months, respectively. There was no anemia, malnutrition, trace element deficiency or other nutrition-related complications during the follow-up, and there was no death. The body mass, body mass index, homeostasis model assessment-insulin resistance, triglyceride, total cholesterol, systolic pressure, diastolic pressure, vitamin D, folate of the 37 patients were (117±19)kg, (40±5)kg/m 2, 6.59(range, 2.84?28.02), (1.6±0.7)mmol/L, (4.5±0.7)mmol/L, (141±22)mmHg (1 mmHg=0.133 kpa), (84±18)mmHg,(14±5)μg/L, (10±5)μg/L before the surgery, and (81±15)kg, (27±4)kg/m 2, 2.69(range, 1.08?9.71), (0.9±0.5)mmol/L, (4.5±0.7)mmol/L, (115±15)mmHg, (70±11)mmHg, (23±10)μg/L, (9±5)μg/L at postoperative 12 months. There were significant differences in the time effect of above indicators ( Ftime=214.14, 160.37, 12.66, 11.77, 2.90, 18.08, 11.32, 8.61, 5.04, P<0.05). The percentages of excess of body mass index lost of the 37 patients were 48%±19%, 77%±28% and 89%±24% at postoperative 3, 6 and 12 months, the percentages of excess weight loss were 42%±13%, 63%±17% and 75%±18%, the percentages of total body weight loss were 18%±5%, 26%±6% and 34%±7%, respectively. There were significant differences in the time effect of above indicators ( Ftime=83.96, 107.24, 109.06, P<0.05). The hemoglobin A1c was 4.8%, 5.0%, 5.1% and 4.9%, 5.2%, 5.2% in the 2 patients with type 2 diabetes at postoperative 3, 6 and 12 months, respectively, and they were relieved without drug treatment.
