Healthy lifestyles and good living habits are effective strategies and important approaches to prevent chronic non-communicable diseases. With the development of evidence-based medicine, the evidence translation system has made some achievements in clinical practice. There is, however, no comprehensive, professional and efficient system for translating lifestyle evidence globally. Therefore, the Health Lifestyle Evidence (HLSE) Group of Lanzhou University constructed the HLSE Evidence Translation System (https://hlse.cn/), with the aim of synthesizing, evaluating, translating, and applying lifestyle-related evidence resources. This paper aims to introduce the functional module design of the evidence translation system, the system development process and testing, introduce the interface design and function demonstration, and explain the significance of constructing the HLSE.

Objective To observe the effects of grain-sized moxibustion on Th1 cell/Th2 cell(Th1/Th2)balance and transcription factors T-box transcription factor(T-bet)and GATA binding protein 3(GATA3)in immunosuppressive mice induced by chemotherapy.Methods According to the random number table method,32 SPF male CD-1(ICR)mice were randomly divided into the normal group,model group,levamisole hydrochloride group,and grain-sized moxibustion group,with eight mice per group.Except for the normal group,the immunosuppressive model was established by intraperitoneal injection of cyclophosphamide(80 mg/kg,once daily for three consecutive days).Mice in the levamisole hydrochloride group were given levamisole hydrochloride solution(10 mg/kg)by gavage.Mice in the grain-sized moxibustion group was given grain-sized moxibustion at"Guanyuan"(CV4),bilateral"Zusanli"(ST36),and bilateral"Sanyinjiao"(SP6),with three Zhuang at each acupoint for approximately 30 s each.The intervention was administered once daily for seven consecutive days.The general condition of mice was observed.The spleen mass and spleen index were detected.The pathological changes of spleen tissue were observed by HE staining.The protein and mRNA expressions of T-bet,GATA3,interferon-γ(IFN-γ),and interleukin(IL)-4 in spleen tissue of mice were detected by Western blotting and real-time PCR.The contents of IFN-γ,IL-2,and IL-4 in serum of mice were detected by enzyme-linked immunosorbent assay.Results Compared with the normal group,the mice in the model group were slow in response,unstable in gait;the spleen weight and spleen index were increased(P<0.05);the structure of spleen tissue was disordered,the mRNA and protein expressions of T-bet and IFN-γ in spleen tissue were decreased,and the mRNA and protein expressions of GATA3 and IL-4 were increased(P<0.05);the contents of IFN-γ and IL-2 in serum were decreased,and the content of IL-4 was increased(P<0.05).Compared with the model group,the general condition of mice in the levamisole hydrochloride group and the grain-sized moxibustion group was improved,the structure of spleen tissue was improved,the mRNA and protein expressions of T-bet and IFN-γ in spleen tissue were decreased,and the mRNA and protein expressions of GATA3 and IL-4 were increased(P<0.05);the contents of IFN-γ and IL-2 in serum were decreased,and the content of IL-4 was increased(P<0.05).Conclusion Grain-sized moxibustion can significantly improve the immunosuppressive symptoms induced by chemotherapy.The mechanism may be through regulating the expressions of transcription factors T-bet and GATA3,regulating Th1/Th2 balance,and thus restoring the immune balance.

Artificial intelligence(AI) empowers the development of the medical industry, providing precise and intelligent assistance for clinical diagnosis, treatment, and rehabilitation.AI has the potential to facilitate shared decision making (SDM), but AI interventions used for SDM are currently in their infancy, presenting both challenges and opportunities. This paper aims to describe the application of AI in SDM, explore the problems and challenges of AI-based decision aid used for SDM, and propose possible solutions, aiming to provide a guide for the development and implementation of AI-based decision aid.

Objective: To investigate the clinicopathological features, immunophenotype, ultrastructure, genetic alterations and prognosis of succinate dehydrogenase-deficient renal cell carcinoma (SDH RCC). Methods: A total of 11 SDH RCCs, diagnosed from 2010 to 2019, were selected from the Department of Pathology of Nanjing Jingling Hospital, Nanjing University School of Medicine for clinicopathologic, immunohistochemical (IHC), ultrastructural investigation and follow-up. The molecular features of seven cases were analyzed by the panel-targeted DNA next generation sequencing (NGS). Results: There were seven males and four females, with ages ranging from 24 to 62 years (mean 41.4 years, median 41 years). Microscopically, SDH RCC was mainly composed of solid and tubular structures with local cystic change. Four cases showed nested or trabecular structure distributed in a loose hypocellular connective tissue or around scar, similar to oncocytoma. The neoplastic cells demonstrated flocculent eosinophilic cytoplasm with typical intracytoplasmic vacuoles. Immunohistochemically, eight cases were negative for SDHB; three cases showed focal and weak expression, whereas normal renal tubular and vascular endothelial cells demonstrated strong cytoplasmic staining. NGS of DNA targeted-panel detected pathogenic mutations of SDHB gene in seven cases (including three cases with equivocal IHC expression of SDHB), without any mutations in other SDH related genes. There were four cases of SDHB missense mutation, one case of frameshift mutation, one case of splicing mutation, and one case of acquired stop codon mutation. Conclusions: SDH RCC is a distinct variant of RCCs with genetic tendency or with hereditary cancer syndrome. NGS is recommended to detect the related gene mutations for a definitive diagnosis. The patients should be closely followed up.

Objective: To investigate the immunohistochemical expression of NKX3.1 and NKX2.2 in mesenchymal chondrosarcoma (MC), and to explore the differential diagnostic value of NKX3.1 and NKX2.2 in MC and other types of small round cell malignant tumors. Methods: A total of 12 cases of MC and 97 other small round cell malignant tumors diagnosed in Jinling Hospital, Nanjing University School of Medicine from 2001 to 2020 were collected for NKX3.1 and NKX2.2 immunohistochemical detection. Among them, two kinds of NKX3.1 antibodies [rabbit polyclonal antibody and rabbit monoclonal antibody (EP356)] were used for detection in 12 cases of MC, and one NKX3.1 antibody (rabbit polyclonal antibody) was detected in 97 cases of other small round cell malignant tumors, and the relevant literature was reviewed. Results: The 12 MC patients included 7 females and 5 males, with a mean age of 33 years (14-54 years). Nine cases were from bone and three from soft tissue. Among the 12 MC patients, 8 patients had postoperative recurrence or metastasis, and 3 of them died of tumor recurrence or metastasis. Histologically, 12 cases of MC showed typical bidirectional differentiation.The positive rate of both NKX3.1 antibodies in MC was 12/12, NKX3.1 was focal weakly positive in only one of 12 chondrosarcomas (grade 3), 5 alveolar rhabdomyosarcomas, 5 embryonal rhabdomyosarcomas, and 5 solitary fibrous tumors, respectively. The remaining 70 cases of other small round cell malignant tumors were negative. The positive rates of NKX2.2 in MC, Ewing sarcoma and olfactory neuroblastoma were 12/12, 15/15 and 4/5, respectively. In 12 cases of chondrosarcoma (grade 3), 5 cases of poorly differentiated synovial sarcoma, 5 cases of alveolar rhabdomyosarcoma, and 5 cases of solitary fibrous tumor, NKX2.2 was focally and weakly positive in only one case, respectively, and all the remaining 50 cases of other small round cell malignant tumors were negative. Conclusions: The expression of NKX3.1 and NKX2.2 proteins are significant indicators in the diagnosis of MC, and the combined detection of NKX3.1 and NKX2.2 can help distinguish MC from most other small round cell malignant tumors.
