Objective To explore the public attitude towards kidney xenotransplantation in China by constructing and validating the prediction model based on xenotransplantation questionnaire. Methods A convenient sampling survey was conducted among the public in China with the platform of Wenjuanxing to analyze public acceptance of kidney xenotransplantation and influencing factors. Using random distribution method, all included questionnaires (n=2 280) were divided into the training and validation sets according to a ratio of 7:3. A prediction model was constructed and validated. Results A total of 2 280 questionnaires were included. The public acceptance rate of xenotransplantation was 71.3%. Multivariate analysis showed that gender, marital status, resident area, medical insurance coverage, religious belief, vegetarianism, awareness of kidney xenotransplantation and whether on the waiting list for kidney transplantation were the independent influencing factors for public acceptance of kidney xenotransplantation (all P<0.05). The area under the curve (AUC) of receiver operating characteristic (ROC) of the prediction model in the training set was 0.773, and 0.785 in the validation set. The calibration curves in the training and validation sets indicated that the prediction models yielded good prediction value. Decision curve analysis (DCA) suggested that the prediction efficiency of the model was high. Conclusions In China, public acceptance of kidney xenotransplantation is relatively high, whereas it remains to be significantly enhanced. The prediction model based on questionnaire survey has favorable prediction efficiency, which provides reference for subsequent research.

Objective To evaluate the clinical efficacy of oral use of Jiawei Puji Xiaodu Granules(mainly composed of Lonicerae Japonicae Flos,Forsythiae Fructus,Taraxaci Herba,Violae Herba,Schizonepetae Herba,Arctii Fructus,Gleditsiae Spina,Paeoniae Radix Rubra,Moutan Cortex,and Phragmitis Rhizoma)combined with external application of Xiaozhong Sanjie Ointment(mainly composed of Scutellariae Radix,Coptidis Rhizoma,Phellodendri Chinensis Cortex,and Gleditsiae Spina,etc.)in the treatment of acute tonsillitis in children,and to observe their effects on the immune function and related inflammatory indexes of the patients.Methods A total of 116 children with acute tonsillitis of heat stagnation in the lung and stomach type were randomly divided into the control group and the observation group,with 58 cases in each group.The control group was treated with Cefixime Dispersible Tablets,while the observation group was treated with Jiawei Puji Xiaodu Granules for oral use and Xiaozhong Sanjie Ointment for external application.Both groups were treated for 14 days and then were followed-up for a period of 6 months.The changes of traditional Chinese medicine(TCM)syndrome scores,white blood cell(WBC)count,T lymphocyte subset CD3+,CD4+,CD8+ and CD4+/CD8+ levels,and serum levels of tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β),interleukin 6(IL-6)and C-reactive protein(CRP)in the two groups were observed before and after the treatment.Moreover,the clinical efficacy and time for the disappearance of clinical symptoms were compared between the two groups,and the occurrence of adverse reactions and the recurrence of tonsillitis in the two groups were monitored at the same time.Results(1)During the trial,there were 8 cases falling off in the control group but none case falling off in the observation group,and eventually 50 cases in the control group and 58 cases in the observation group completed the full course of treatment.(2)After 14 days of treatment,the total effective rate of the observation group was 98.28%(57/58),while that of the control group was 90.00%(45/50).The intergroup(tested by rank sum test)showed that the clinical efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(3)After treatment,the time for the disappearance of sore throat,time for the disappearance of purulent spots,time for subsiding fever and time for the tonsils recovering to normal in the observation group were all significantly shorter than those in the control group(P＜0.05).(4)After treatment,the scores of primary and secondary symptoms and the overall symptom scores in the two groups were significantly lower than those before treatment(P＜0.05),and the reduction of the scores in the observation group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the levels of T lymphocyte subset CD3+,CD4+ and CD4+/CD8+ in the two groups were significantly higher(P＜0.05)while the level of CD8 + was significantly lower(P＜0.05)than those before treatment,and the increase in the levels of CD3+,CD4+ and CD4+/CD8+ and the reduction of the CD8+ level of the observation group were significantly superior to those of the control group(P＜0.05).(6)After treatment,the levels of WBC,TNF-α,IL-1β,IL-6 and CRP in the two groups were significantly lower than those before treatment(P＜0.05),and the reduction in the observation group was significantly superior to that in the control group(P＜0.05).(7)During the treatment period,no skin allergy,nausea,vomiting or other gastrointestinal adverse reactions occurred in the two groups,which showed a high degree of safety.(8)The 6-month follow-up showed that the recurrence rate of tonsillitis in the observation group was 5.17%(3/58),which was significantly lower than that of 24.00%(12/50)in the control group,and the difference was statistically significant(χ2 = 8.330,P＜0.05).Conclusion The efficacy of Jiawei Puji Xiaodu Granules combined with Xiaozhong Sanjie Ointment exert notable curative effect for children with acute tonsillitis of heat stagnation in the lung and stomach type.The combined therapy can significantly shorten the duration of the disease,improve the clinical symptoms of the children and effectively reduce the recurrence rate of tonsillitis.The therapeutic mechanism may be related to the enhancement of the immune function and the inhibition of inflammatory response.

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.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Objective To investigate the mechanism of 2,6-dimethoxy-1,4-benzoquinone(DMQ),an active ingredients in fermented wheat germ extract,for inhibiting NLRP3 inflammasome activation and alleviating septic shock in mice.Methods Cultured murine bone marrow-derived macrophages(BMDM)stimulated with lipopolysaccharide(LPS)were treated with DMQ,followed by treatment with Nigericin,ATP,and MSU for activating the canonical NLRP3 inflammasome;the non-canonical NLRP3 inflammasome was activated by intracellular transfection of LPS,and AIM2 inflammasome was activated using Poly A:T.In human monocytic THP-1 cells,the effect of Nigericin on inflammasome activation products was examined using Western blotting and ELISA.Co-immunoprecipitation was performed to explore the mechanism of DMQ-induced blocking of NLRP3 inflammasome activation.In a male C57BL/6J mouse model of LPS-induced septic shock treated with 20 and 40 mg/kg DMQ,the levels of IL-1β and TNF-α in the serum and peritoneal lavage fluid were determined using ELISA,and the survival time of the mice within 36 h was observed.Results Treatment with DMQ effectively inhibited LPS-induced activation of canonical NLRP3 inflammasome in mouse BMDM and human THP-1 cells and also inhibited non-canonical NLRP3 inflammasome activation in mouse BMDM,but produced no significant effect on AIM2 inflammasome activation.DMQ significantly blocked the binding between ASC and NLRP3.In the mouse models of septic shock,DMQ treatment significantly reduced the levels of IL-1β in the serum and peritoneal fluid and obviously prolonged survival time of the mice.Conclusion DMQ can effectively block ASC-NLRP3 interaction to inhibit NLRP3 inflammasome activation and alleviate LPS-induced septic shock in mice.
