To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Doctor-patient communication not only depends on the medical group but is also affected by the patient group and the specific situation. Effective doctor-patient communication requires the doctors to improve their communication skills， the patients to have relevant knowledge regarding a certain symptom or disease， and mutual trust between the doctor and patient. The information ecology theory mainly analyzes the relationships between various ecological elements and the ecological development mechanisms in the process of information activities from the perspective of the ecosystem， as well as attaches importance to the mutual influences and roles of information subjects and objects， information contents， information environment， and information technology within the system， which is consistent with the influencing factors of doctor-patient communication. Based on the information ecology theory， this paper analyzed the new problems faced by doctor-patient communication under the information technology environment from the four dimensions， including information subjects and objects， information itself， information context， and information technology. It was proposed that effective doctor-patient communication required to re-examine the influencing factors of doctor-patient communication， as well as construct a doctor-patient community， including a community of knowledge， communication， emotion， and interest， so that the four factors of doctor-patient communication can form a new balance in the dynamic development， with a view to providing practical guidance for doctor-patient trust and effective doctor-patient communication.

BACKGROUND:Human periodontal stem cells have a certain inhibitory effect on the pro-inflammatory function of M1-type macrophages,and it is not clear whether icariin,which has anti-inflammatory and other pharmacological activities,can enhance the inhibitory effect of human periodontal stem cells on M1-type macrophages. OBJECTIVE:To investigate the effect of icariin on M1 macrophages after pretreatment of human periodontal stem cells. METHODS:Primary human periodontal stem cells were isolated,cultured and characterized.THP-1 was induced and M1-type macrophages were identified by immunofluorescence staining and PCR.Human periodontal stem cells were cultured with α-MEM complete medium containing concentrations of 10-7,10-6,10-5,and 10-4 mol/L icariin,and the cytotoxicity of Icariin on human periodontal stem cells was detected by the CCK-8 assay at 1,3,5,and 7 days,respectively.α-MEM complete medium,untreated α-MEM conditioned medium for human periodontal stem cells and α-MEM conditioned medium for human periodontal stem cells pretreated with icariin for 24 hours were conditioned with RPMI-1640 complete medium in a 1:1 ratio for M1-type macrophages in the control,untreated,and pretreated groups,and 24 hours later,the mRNA expression of inflammatory factors in M1 macrophages was detected by RT-PCR.The protein expression of inflammatory factors in M1 macrophages was detected by ELISA.The expression of surface markers and nuclear factor-κB pathway-related proteins in M1/M2 macrophages was detected by western blot assay. RESULTS AND CONCLUSION:(1)CCK-8 assay results showed that 10-7,10-6,10-5,10-4 mol/L icariin was not cytotoxic to the human periodontal stem cells,and from day 5 onwards,all the concentrations increased the cell viability,and promoted the cell proliferation.10-4 mol/L icariin was selected for follow-up experiment.(2)RT-PCR and ELISA results showed that compared with the control group,the untreated group and the pretreated group both decreased the expression and secretion of interleukin-1β,interleukin-6,and tumor necrosis factor-α of M1-type macrophages(P<0.05),and the pretreated group was lower than the untreated group(P<0.05).(3)Western blot assay results showed that compared with the untreated group,the expression of CD86 was significantly lower in the pretreated group(P<0.05);compared with the control group,the expression of CD206,a surface marker of M2-type macrophages,was elevated in both the untreated and pretreated groups(P<0.01),and it was significantly higher in the pretreated group than in the untreated group(P<0.01).In M1-type macrophages after 24 hours of conditioned culture,compared with the control group,the expression of nuclear factor-κB/P65 was decreased in the untreated group and the pretreated group(P<0.01),and the expression of p-IκBα was decreased only in the pretreated group(P<0.01);the expression of both nuclear factor-κB/P65 and p-IκBα was significantly reduced in the pretreated group compared with the untreated group(P<0.05),while the difference of IκBα in the three groups was not statistically significant.(4)These results indicated that icariin enhanced the inhibitory effect of human periodontal stem cells on M1-type macrophages,and this effect may be related to the inhibition of the nuclear factor-κB signaling pathway of macrophages.

Purpose This study aimed to explore the mucinous phenotype characteristics,key points of differenti-al diagnosis and prognosis of invasive non-mucinous adenocarcinoma(INMA)and invasive mucinous adenocarcinoma(IMA)under the WHO(2021)lung adenocarcinoma classification.Methods We retrospectively collected clinico-pathological data from 522 cases of lung adenocarcinoma,including 425 INMA(66 with mucin secretion,259 without mucin secretion)and 97 IMA.Immunohistochemical(IHC)staining using the EnVision method was performed on the mucin-secreting adenocarcinoma to assess expression of TTF-1,HNF4α,MUC1,MUC4,MUC5AC,MUC5B,and MUC6.Unsupervised clustering analysis was conducted to explore phenotypic subgroups.Results 522 patients with lung adenocarcinoma ranged from 32 to 83 years old(median:61).251 cases(48.1％)were male and 271 cases(51.9％)were female.Clustering analysis divided lung adenocarcinomas into two major groups:one characterized by TTF-1-/HNF4α+and gastric-type mucins MUC5AC+/MUC6+,predominantly IMA;the other,TTF-1+/HNF4α-/MUC4+,largely INMA.A three-marker IHC panel(TTF-1,HNF4α,MUC6)distinguished IMA from mucinous IN-MA with an area under the ROC curve(AUC)of 0.957(95％CI:0.928-0.986)and a Youden's index of 0.860.Further cluster analysis of INMA cases identified four phenotypic subgroups.Prognostic analysis demonstrated that pa-tients with advanced-stage mucin-secreting INMA had significantly shorter overall survival(OS)and progression-free survival(PFS)than those without mucin secretion(5-year OS:57.1％ vs 81.8％,P=0.004;3-year PFS:40.9％ vs 62.4％,P=0.004).No significant survival differences were noted among INMA subgroups stratified by varying mucin proportions.Multivariate analysis identified pathological stage,tumor necrosis,KRAS mutation,and TTF-1 negativity as independent adverse prognostic factors for both OS and PFS in mucinous INMA.Conclusion A three-marker im-munohistochemical panel of TTF-1,HNF4α,and MUC6 is recommended to distinguish IMA from mucinous INMA.Mucus component portends a worse prognosis in advanced INMA,with necrosis,KRAS mutations,and TTF-1 negativi-ty serving as independent adverse prognostic factors in mucinous INMA.

Sleep disorders is one of the most frequent and severe complications in patients with tinnitus and is highly correlated with the severity of tinnitus.Sleep disorders and tinnitus influence each other,forming a vicious circle.While in-terventions have been developed to alleviate tinnitus distress,these interventions are usually not effective in improving sleep in patients with tinnitus and sleep disorders.Helping tinnitus patients to resolve sleep disorders is the key to breaking the cycle and improving their quality of life.In this narrative review,we studyed the current state of research on sleep disorders in patients with tinnitus through three aspects:epidemiology,physiological and psychological mechanisms,and existing psychological,physical,and pharmacological interventions,and to provide a basis for further research on the relationship between tinnitus and sleep disorders and the precise treatment of tinnitus.

Objective To observe the effects of acupuncture at"Weizhong"on angiogenesis of chronic blunt injury of lumbar muscle in rats;To explore the possible mechanism of acupuncture in the treatment of chronic lumbar skeletal muscle injury based on PI3K/AKT/HIF-1α signaling pathway.Methods A total of 24 SD male rats were established chronic blunt injury of lumbar muscle model,and were randomly divided into model group,Weizhong group and non-acupoint group,with 8 rats in each group.Another 8 rats of the same age were selected as the blank group.In the Weizhong group,acupuncture intervention was performed on both sides of"Weizhong",while in the non-acupoint group,acupuncture intervention was performed on both sides of"Weizhong"inwardly by 0.5 cm,once a day for 20 minutes each time,for 2 consecutive weeks.The blank group and model group adopted the same grasping fixed posture without any intervention.The body mass and limb grip strength of each group were measured,the lumbar muscle tissue morphology was observed by HE staining,the content of NO in lumbar muscle tissue was detected by ELISA,the expression of VEGF in lumbar muscle tissue was observed by immunofluorescence,the expression of PI3K/AKT/HIF-1α pathway protein in lumbar muscle tissue was detected by Western blot.Results Compared with the blank group,body mass and limb grip strength of model group decreased(P<0.01),cell structure of waist skeletal muscle was loosely arranged,red blood cells and nuclear exudation were observed,NO content and positive expression of VEGF in lumbar muscle tissue decreased(P<0.01),and the protein expressions of p-PI3K/PI3K,p-AKT/AKT and HIF-1α in lumbar muscle tissue were down-regulated(P<0.01).Compared with the model group,the body mass and limb grip strength of rats in Weizhong group increased(P<0.05,P<0.01),the arrangement of skeletal muscle cells in the waist was more compact and orderly,and the content of NO and positive expression of VEGF in lumbar muscle tissue were increased(P<0.01),the protein expressions of p-PI3K/PI3K,p-AKT/AKT and HIF-1α in lumbar muscle tissue were up-regulated(P<0.01).The effects of Weizhong group was better than those in non-acupoint group(P<0.05,P<0.01).Conclusion Acupuncture at"Weizhong"can effectively promote the repair of chronic blunt injury of lumbar muscle in rats.The mechanism may be related to activating the PI3K/AKT/HIF-1α pathway to regulate angiogenesis and improve vascular injury.

Postoperative lower limb lymphedema following gynecological malignancies can be categorized under TCM concepts of"edema"and"meridian obstruction".Professor Jia Liqun believes that the underlying deficiency lies in yang and blood deficiency,while the excess is characterized by dampness and blood stasis obstructing the meridians.Consequently,the treatment strategies include warming yang and nourishing blood to unblock the meridians,dispelling dampness and promoting diuresis to unblock the meridians,and transforming stasis and promoting diuresis to unblock the meridians.Clinical practice requires dynamic syndrome differentiation and treatment according to the disease progression.Additionally,Professor Jia often employs the external application of Wenjing Tongluo Powder to directly target the affected area,combining internal and external treatments to enhance the effect of unblocking the meridians and reducing swelling.
