Diabetic ulcer （DU） wound is one of the chronic and serious complications of diabetes characterized by prolonged wound healing， and it is more common in foot and lower extremity ulcers. DU has brought great economic and psychological pressure to patients and seriously affected the quality of life of patients because of its great difficulty in treatment， long treatment process， and high morbidity and mortality. Therefore， how to help the rapid healing of DU wounds， reduce the disability rate and mortality rate， protect limb function， and improve the quality of life is an important topic and hot spot in the field of medical research. The pathogenesis of DU is complex， mainly including microcirculation disorder， peripheral neuropathy， inflammation and infection， and excessive apoptosis of cells， involving physiological processes such as wound inflammation， granulation tissue hyperplasia and re-epithelialization. A large number of previous studies have found that Chinese medicine can regulate phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Wnt/β-catenin， nuclear factor-κB （NF-κB）， Notch， nuclear factor E₂-related factor 2 （Nrf2）， transforming growth factor-β （TGF-β）/Smad， and other signaling pathways， regulate abnormal glucose metabolism， improve microcirculation， inhibit inflammation and oxidative stress， regulate cell proliferation and excessive apoptosis， and promote wound tissue growth to promote the rapid healing of DU wounds under the guidance of treatment based on traditional Chinese medicine （TCM） syndrome differentiation and internal and external treatment. Therefore， this paper reviewed Chinese medicinal monomers or Chinese medicinal compounds in recent years in regulating the above signaling pathways and the expression of key protein molecules and promoting the rapid healing of DU wounds， aiming to provide ideas and a theoretical basis for the in-depth study and clinical application of Chinese medicine in promoting the healing of DU wounds.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

Objective:To explore the efficacy of online pulmonary rehabilitation (PR) management among community-dwelling patients with stable chronic obstructive pulmonary disease (COPD).Methods:This study was a single-center randomized controlled trail with an unblinded design. A total of 130 patients with stable COPD who visited Zhuanqiao Community Health Service Center in Shanghai Minhang District from October 2020 to March 2022 were randomly divided into study group and control group with 65 cases in each group. Both groups received conventional treatment, while patients in study group attended online rehabilitation management, including face-to-face rehabilitation instruction and multiple online guidance. Pulmonary ventilation function including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1) and percentage of forced expiratory volume in the first second to forced expiratoty volume (FEV 1%pred), modified British Medical Research Council Dyspnea Scale (mMRC), chronic obstructive pulmonary disease assessment test (CAT), score of 6 minutes walking distance (6MWD) and DOSE (dyspnea, degree of airflow obstruction, smoking status, the number of exacerbation) index were measured at baseline and after 8 weeks of rehabilitation, and compared between two groups. Results:The baseline data of the two groups were comparable. After 8 weeks of management, FVC, FEV 1, FEV 1%pred, mMRC, CAT, 6MWD and DOSE index of both groups were improved compared with the baseline level(control group: t=-7.799, -7.581, -9.010, 3.565, 9.887, -16.677, 3.795; study group: t=-12.623, -13.914, -17.644, 7.404, 22.457, -26.826, 7.968; all P<0.05). The FEV 1%pred, CAT and 6MWD in the study group were better than those in the control group ( t=-2.939, 2.277,-2.130, all P<0.05); while there were no significant differences in FVC, FEV 1, mMRC and DOSE index between the two groups( t=-0.162, -1.280, 0.925, 1.939,all P>0.05). Conclusions:The online pulmonary rehabilitation management can better improve lung function, dyspnea symptoms and exercise tolerance of patients with stable COPD, which can be used for rehabilitation training and management of community-dwelling patients.

Flap surgery is a complex surgical procedure that has become an effective method for the treatment of many diseases and traumas. Flap survival is closely related to a variety of factors including cellular autophagy, oxidative stress, inflammatory response, mesenchymal stem cells (MSCs) function, and vascular regeneration. Cellular autophagy maintains intracellular homeostasis and plays a key role in reducing oxidative stress and inflammation and promoting injury repair. Excessive oxidative stress and inflammatory responses pose a threat to flaps, affecting their survival and successful transplantation. Endothelial cells are involved in vascular regeneration through proliferation, migration, and production of angiogenic factors, and vascular endothelial growth factor directly promotes blood vessel formation and maintains endothelial cell function.MSCs play an important role in promoting flap survival and tissue repair due to their unique biological properties and multiple mechanisms of action. The multiple roles played by cellular autophagy, oxidative stress, inflammatory response, MSCs function, and vascular regeneration in influencing postoperative flap survival are hereby elaborated. The aim is to provide a basis for the clinical application of regulating the above factors to improve postoperative flap survival, improve the success rate of flap surgery, reduce complications, and bring more hope for the recovery and quality of life of patients.

The relevant data reported by laboratories carrying out serological prenatal screening in Jiangsu Province from 2021 to 2022 were retrospectively analyzed, and the provincial inter-ventricular quality assessment was realized by comparing the internal quality control data of laboratories. The quality control analysis platform of prenatal screening in Jiangsu Province was used to collect the determination methods, quality control data results of three concentrations, instrument platform, reagents and other relevant information of maternal serological screening quality control in early and middle pregnancy in each laboratory from 2021 to 2022. Firstly, the test results of each laboratory were statistically analyzed, and the precision of each laboratory was evaluated by the variation coefficient of indoor quality control. Secondly, the consistency was evaluated by comparing laboratories with different experimental platforms. The results showed that the passing rate of PAPP-A(pregnancy-associated plasma protein-A) precision test in 2021 and 2022 was 87.5% (7/8) and 92.3% (12/13), respectively. The accuracy pass rate of the Free β-hCG (free beta-human chorionic gonadotrophin)(early pregnancy) test in 2021 and 2022 was 97.5% (39/40) and 95.5% (42/44), and the accuracy pass rate of the AFP(alpha-fetal protein) test in 2021 and 2022 was 100% (40/40) and 90.9% (40/44), respectively. The accuracy pass rate of Free β-hCG (middle pregnancy) test in 2021 and 2022 was 100% (40/40) and 95.5% (42/44), respectively. The consistency of each index was 100%. In conclusion, the relevant data reported by laboratories carrying out serological prenatal screening in Jiangsu Province has a high consistency, and for a small number of laboratories with poor stability, it is necessary to make periodic evaluation and rectification according to the data analysis results, so as to improve the quality control management of maternal serological prenatal screening.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Objective:To explore the cost-effectiveness and cost-benefit of chronic obstructive pulmonary disease (COPD) screening and intervention based on family doctor contract services.Methods:From January 2023 to October 2023, using purposive sampling and a cross-sectional survey method, 1 040 individuals aged 60 to 75 years who underwent physical examinations at community health service centers in Shanghai Minhang district were selected as research subjects. The subjects were divided into a control group ( n=532) and a study group ( n=508). The control group received conventional community health education and participated in a COPD screening and intervention program provided by the examination center. The study group received COPD screening and intervention provided by contracted family doctors under a tightly integrated medical consortium. The screening content for both groups included initial and follow-up risk assessment questionnaires, pulmonary function tests, bronchodilator tests, and CT scans. A comparative analysis was conducted on the screening compliance rate, positive rate, and cost-effectiveness and cost-benefit between the two groups. Results:A total of 251 individuals at high risk for COPD and confirmed COPD patients were identified through initial and re-screening in both groups, accounting for 24.13% of the subjects, including 222 individuals at high risk (21.35%) and 29 confirmed patients (2.79%). The study group had significantly higher compliance rates in questionnaire-based initial screening, questionnaire-based re-screening+pulmonary function tests, bronchodilator experiments, diagnosis, and subsequent CT scans than the control group ( χ2=33.563, 41.425, 24.842, 17.363, all P<0.05).There were significant higher proportions of high-risk individuals and patients identified through screening in the study group than those in the control group ( χ2=44.880, all P<0.05). The study group had significantly higher positive rates of questionnaire-based initial screening, pulmonary function tests, bronchodilator experiments, and CT scans than the control group ( χ2=29.191, 11.313, 12.370, 4.429, all P<0.05). The overall costs of the screening in the control and study groups were 36 100 and 53 900 yuan, respectively. The cost of pulmonary function tests in the screening for the control and study groups was 1.44 million and 2.45 million yuan, respectively, accounting for 43.19% of the total cost, which was the highest proportion among all costs. The per capita cost for identifying one high-risk individual or patient with COPD was 358.46 Yuan, and the cost in study groups was significantly lower than that in the control group (322.75 vs. 429.45 yuan, χ2=20.396, P<0.05). The per capita net benefits and cost-benefit ratios for the overall subjects in the two groups were 0.37 million yuan and 43.50, respectively. The average net benefit of the study group and the control group was 0.49 million yuan and 0.26 million yuan respectively. The average net benefit of the study group was 0.23 million yuan higher than that of the control group. The cost-benefit ratio of the study group and the control group were 46.77 and 38.61, respectively. The cost-benefit ratio of the study group was 8.16 higher than that of the control group. Conclusion:The screening and intervention for COPD based on family doctor contract services have significant effectiveness, with a marked improvement in screening compliance and high cost-effectiveness, and can be used in community medical institutions with relatively sound family doctor and medical consortium services for targeted COPD screening.
