Neurodegenerative disorders (NDDs) are prevalent chronic conditions characterized by progressive synaptic loss and pathological protein alterations. Increasing evidence suggested that mitochondrial quality control (MQC) serves as the key cellular process responsible for clearing misfolded proteins and impaired mitochondria. Herein, we provided a comprehensive analysis of the mechanisms through which MQC mediates the onset and progression of NDDs, emphasizing mitochondrial dynamic stability, the clearance of damaged mitochondria, and the generation of new mitochondria. In addition, traditional Chinese medicines (TCMs) and their active monomers targeting MQC in NDD treatment have been demonstrated. Consequently, we compiled the TCMs that show great potential in the treatment of NDDs by targeting MQC, aiming to offer novel insights and a scientific foundation for the use of MQC stabilizers in NDD prevention and treatment.

Objective This essay excavates the contents of urinary diagnosis in the Four Tantras and visualize the invisible experience knowledge of urinary diagnosis of Jenesake disease(type II diabetes)based on clinical medical records.It also explores the digitization and visualization of original thinking of Tibetan medicine,clinical diagnosis and treatment and modern science and technology,and clinical invisible experience and knowledge.Methods The contents of urinary diagnosis in the Four Tantras were deeply explored by literature method.And 355 cases of Jenesake disease c were analyzed by Gephi,Spsspro,traditional Chinese medicine inheritance computing platform and other software.Results Urology in Tibetan medicine has a long history,with a development period of one thousand years and has a systematic and complete theoretical system.The three-times and nine-diagnosis method of urinary in Tibetan medicine recorded in the Four Tantras is unique and plays an important role in the diagnosis of clinical diseases.According to the analysis of 355 clinical cases of Jenesake disease,urine diagnosis was slightly different according to different syndrome types,the overall color was light yellow,cyan,yellow,relatively bright,close to normal urine color.Steam and smell are big;The foam is bluish and large or dissipates quickly;Few or hairy suspensions;The float is thin;Change time for the hot gas is not finished began to change;The pattern of change from the thin middle to the edge;Cyclotron condition from thin to thick and other characteristics.The frequency analysis of urinary diagnosis syndromes showed that 139 cases of Chiba type,91 cases of lung type,88 cases of bacon type and 34 cases of Pechi type.Conclusion Urology in Tibetan medicine has a complete theoretical system and rich experience in clinical practice.Through the method of combining literature mining and clinical medical cases,this paper expands the contents of the three-time and nine-time urine diagnosis of Jenesake disease in Tibetan medicine and combines the original thinking of Tibetan medicine with modern information technology to realize the visualization of the invisible experience knowledge of Jenesake disease urine diagnosis in Tibetan medicine.

Heart failure(HF)is a highly morbid syndrome that seriously affects the physical and mental health of patients and generates an enormous socio-economic burden.In addition to cardiac myocyte oxidative stress and apoptosis,which are considered mechanisms for the development of HF,alterations in cardiac energy metabolism and pathological autophagy also contribute to cardiac abnormalities and ultimately HF.Silent information regulator 1(Sirt1)and adenosine monophosphate-activated protein kinase(AMPK)are nicotinamide adenine dinucleotide(NAD+)-dependent deacetylases and phosphorylated kinases,respectively.They play similar roles in regulating some pathological processes of the heart through regulating targets such as peroxisome proliferator-activated receptor γ coactivator 1α(PGC-1α),protein 38 mitogen-activated protein kinase(p38 MAPK),peroxisome proliferator-activated receptors(PPARs),and mammalian target of rapamycin(mTOR).We summarized the synergistic effects of Sirt1 and AMPK in the heart,and listed the traditional Chinese medicine(TCM)that exhibit cardioprotective properties by modulating the Sirt1/AMPK pathway,to provide a basis for the development of Sirt1/AMPK activators or inhibitors for the treatment of HF and other cardiovascular diseases(CVDs).

【Objective】   As the main active ingredient of Tibetan medicine Hongjingtian (Rhodiolae Crenulatae Radix et Rhizoma), salidroside (Sal) has a good anti-apoptotic potential. Currently, there are some conflicting results on the anti-apoptotic mechanisms of Sal. Here we conducted a systematic review and meta-analysis to provide the preclinical evidence of its anti-apoptotic properties in preventing and treating hypoxic-ischemic cerebral damage(HICD). 【Methods】   The literature on the anti-apoptotic potential of Sal in the treatment of HICD from January 1, 1980 to November 9, 2021 was searched online using Chinese databases including Chinese National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang Database, and English databases including PubMed and Web of Science. The quality of the included articles was evaluated by the Cochrane Collaboration network bias risk assessment criteria, and meta-analysis was performed using RevMan 5.3 software. 【Results】  A total of 40 articles were finally included. Among the 40 articles, 30 were about in vivo animal experiments and 17 about in vitro cell experiments, and 7 of them included both animal and cell experiments. After analysis, it was found that Sal had significant effects on disease-related indicators of HICD (P < 0.05), such as cerebral infarctsize and brain water content. As to in vivo studies, Sal mainly affects the expressions of apoptotic factors through antiinflammation, anti-oxidation, activation of complement pathway, and regulation of signal transduction and autophagy, thus exerting anti-apoptotic potential in treating HICD. While for in vitro studies, Sal plays the anti-apoptotic role in HICD models mainly through anti-oxidation, anti-inflammation, reduction of Ca2+ overload, regulation of mitochondrial function, signal transduction, and C3 complement. 【Conclusion】  Sal can take anti-apoptotic effects to prevent and treat HICD through mechanisms such as anti-inflammation, anti-oxidation, enhanced autophagy, complement and signal transduction, regulation of mitochondrial membrane potential, and reduction of Ca2 + overload.

Objective:To explore the cognition and attitude of urological nurses towards patients′ sexual health education, and to provide basis for the development of urological patient sexual health education.Methods:The research was based on the phenomenology research method. Qualitative research were used to conduct semi-structured personal in-depth interviews with 18 nursing staff who are from 5 tertiary general hospitals in Shanghai, Shandong, Hainan, Anhui and Xinjiang Uygur Autonomous Region using a purposive sampling, data were analyzed by claizzi phenomenological data 7-step analysis method.Results:After refining, two categories and five themes were obtained, including vague concepts (confusion of concepts, lack of roles, lack of theoretical knowledge), neglect and avoidance (respect for patients′ wishes, low priority).Conclusions:Urological nurses have low ability to evaluate the needs of patients′ sexual health education, and the content of sexual health education was one-sided, the form was single, and the degree of preparation was low, so they can not provide personalized and standardized health education for patients. We should carry out education in multiple ways for urological nurses, develop a tool for assessing the needs of urological patients′ sexual health education in China as soon as possible, formulate a standardized and personalized sexual health education standard, and provide comprehensive, systematic and consistent sexual health education for patients, so as to improve the sexual health level of urological patients.

Objective: To analyze the mechanism of metformin in improving oxaliplatin resistance of colorectal cancer cells. Methods: The expression levels of EIF3G in 71 cases of colorectal cancer and adjacent tissues were detected by RT-qPCR. The survival curve was established by Kaplan-Meier method. The survival rate difference between the two groups was compared by Log-rank test.HCT-116 cells were infected with shEIF3G lentivirus, HCT-116 L-OHP-resistant cell line was constructed.After treated with metformin, sensitivity to L-OHP was detected by CCK-8 assay, RT-qPCR and Western blot were used to analyze the EIF3G mRNA and protein levels. The subcutaneous tumor model of nude mice was constructed to observe the effect of metformin on tumor growth. Results: The expression level of EIF3G mRNA in colorectal cancer tissues was up-regulated by (3.24±0.43) times compared with paraneoplastic tissues (P<0.01). EIF3G level was significantly correlated with the prognosis of colon cancer patients. Knockdown EIF3G could enhance the L-OHP sensitivity of HCT116/L-OHP cells (P<0.05); Metformin can reduce the expression level of EIF3G and improve the drug resistance of HCT116/L-OHP cells (P<0.05), and inhibit the development of colorectal cancer in vivo (P<0.05). Conclusion Metformin can inhibit the expression of EIF3G and improve the L-OHP resistance of HCT-116 cells.

In cultivating surgeons in laparoscopy in our country, there are some deficiencies such as unbalanced regional development, technical difficulties, long learning curve, lack of standardized training mode and so on. Based on the original foundations, the Department of Gastrointestinal Surgery, Tangdu Hospital, the Air Force Military Medical University, has been constructing and improving the cultivating system by modifying the course contents, improving the training of endoscopic simulator, endoscopic surgery training on animal and endoscopic clinical practice, and managing the processes. Based on the above measures, certain results have been achieved.

Objective To compare the CT features and pathology of pulmonary solitary fibrous tumor (SFT),to improve the diagnosis and differential diagnosis.Methods CT images and corresponding pathological results of 14 cases with pulmonary SFT were analyzed retrospectively. Results Among the 14 cases,6 were in the right lung and other 8 were in the left.The maximum diameters of tumors were ranged from 2.5 cm to 20.0 cm,and 6 cases were over 10.0 cm.All 14 cases represented as irregular solid nodule or mass,4 as unclear boundary and 1 as lobulation.Most of the cases showed heterogeneous and progressive enhancement.The light microscopy showed that tumor tissues were mainly composed of collagen fibers and spindle cells with different proliferation degrees,and 3 cases showed atypia cells.There were abundant blood vessels in the intercellular substance.Immunohistochemistry were done in 13 cases,presenting Bcl-2,CD99 and Vimentin positive expressions in all cases and CD34 expression in 9.Conclusion The CT features of pulmonary SFT are related to pathological features.CT scan is important in the localization and qualitative diagnosis of pulmonary SFT,and obvious inhomogeneous map-like and progressive enhancement should be considered for the diagnosis of SFT.

OBJECTIVE:To establish the method for the determination of oleanolic acid and ursolic acid in different medicinal parts of Tibetan medicine Pteocephalus hookeri,and compare the differences among the different parts. METHODS:The contents of oleanolic acid and ursolic acid from different medicinal parts(whole plant,aerial part,underground part)of P. hookeri were de-termined by UPLC-PDA. The separation was performed on Acquity UPLC HSS T3 column(150 mm×2.1 mm,1.8 μm)with mobile phase consisted of methanol-0.1 mol/L ammonium acetate(88:12,V/V)at the flow rate of 0.2 mL/min. The detection wavelength was set at 210 nm,and column temperature was 30 ℃. The sample size was 5 μL. RESULTS:The linear ranges of oleanolic acid and ursolic acid were 10.65-1065 μg/mL (r=0.9996) and 18.8-1880 μg/mL (r=0.9994),separately. The recoveries were 96.95%(RSD=1.24%,n=9) and 98.12%(RSD=2.13%,n=9),separately. RSDs of precision,stability and reproducibility tests were all less than 3%. The contents of oleanolic acid and ursolic acid from different medicinal parts in P. hookeri were in de-scending order of aerial part>whole plant>underground part;the average total content of oleanolic acid and ursolic acid from whole plants was 0.35%,the aerial part reached 0.56% and underground part was 0.09%. CONCLUSIONS:The method is rapid, accurate and reproducible,and it is suitable for the content determination of oleanolic acid and ursolic acid in different medicinal parts of Tibetan medicine P. hookeri. The contents of oleanolic acid and ursolic acid from aerial part of P. hookeri are higher than whole plant and underground part. It is suggested to use aerial parts of medicine.
