With the technological progresses and applications of human genome sequencing, bioinformatics analysis and data mining, and molecular pathology and artificial intelligence-assisted pathological diagnosis, the development of clinical medicine is moving towards the era of precision diagnosis and treatment. In the context of this era, the traditional diagnostic pathology is facing unprecedented opportunities and challenges in our history and is striving towards the "next-generation diagnostic pathology" (NGDP). NGDP is based on histomorphology and clinical data, and characterized by the combination of molecular detection and bioinformatics analysis, intelligent sampling and process quality control, intelligent diagnosis and remote consultation, lesion visualization and "non-invasive" pathology as well as other innovative cutting edge interdisciplinary technologies. The NGDP reports will include the results from multi-omics and cross-scale integrated diagnosis for final diagnosis. NGDP will also be applied for predicting disease progression and outcomes, and determining optional therapeutics as well as assessing treatment responses, so that a novel "golden standard" of disease diagnosis can be established. In the near fature, it is necessary to stimulate the innovative vitality of pathology disciplines, accelerate the maturity and application for NGDP, update the theory and technical system of pathology, and perform its important applicable role in the prevention, diagnosis, treatment of diseases so that the futher development of clinical medicine will be promoted and the strategy for maintenance of being healthy in China will be served.

ObjectiveTo explore the mechanism of Shenxiong glucose injection （SGI） in inhibiting hydrogen peroxide （H2O2）-induced oxidative damage in H9c2 cells by tandem mass tags （TMT）-labeled quantitative proteomics. MethodH9c2 cells cultured in vitro were exposed to H2O2 for inducing oxidative damage. The cell viability was measured by cell proliferation and cytotoxicity assay （MTS）， followed by peptide fractionation by high performance liquid chromatography （HPLC） and protein expression detection in H9c2 cells by ultrahigh performance liquid chromatography-mass spectrometry. MaxQuant （v1.5.2.8） was utilized for data retrieval， and the high-resolution mass spectrometry was conducted to screen out differentially expressed proteins， which were then subjected to gene ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis. The protein expression levels of perilipin 2 （Plin2） and tropomyosin 1 （Tpm1） in cells were measured by Western blot. ResultThe spectral analysis yielded 48 608 specific peptide fragments and 5 903 quantifiable proteins. Compared with the model group，the SGI group exhibited 82 differentially expressed proteins，of which 22 were up-regulated and 60 were down-regulated. GO analysis results showed that the differentially expressed proteins were mainly involved in biological processes such as programmed cell death regulation，regulation of cell proliferation，cardiovascular system development， and cell migration. As revealed by KEGG analysis， these proteins were mainly related to peroxisome proliferator-activated receptor （PPAR），focal adhesion，phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt），and Ras-related protein 1 （Rap1） pathways. Western blot results demonstrated that compared with the model group，SGI significantly increased the Plin2 protein expression and decreased the Tpm1 protein expression （P<0.01），consistent with the proteomics results. ConclusionSGI may inhibit cell apoptosis and antagonize H2O2-induced cell oxidative damage by regulating PPAR，focal adhesion，PI3K/Akt and Rap1 pathways，which should be further verified by subsequent experiments.

ABSTRACT
OBJECTIVE: Yang deficiency constitution may bring with different types of illnesses in many people. The present study was designed to observe the effect of ginger-separated snake moxibustion on yang deficiency symptom, and serum adrenocorticotropic hormone (ACTH) and cortisol (CORT) contents in yang deficiency constitution subjects, so as to explore its mechanism underlying improvement of yang deficiency constitution. METHODS: Ninety subjects with yang deficiency type constitution were equally and randomly assigned to control A group (19 men and 26 women, 18－60 years in age) and moxibustion group (16 men and 29 women, 18－60 years in age) and 45 normal subjects with mild constitution (18 men and 27 women, 18－60 years in age) were assigned to control B group. An snake-like moxa-cone was placed at a moxa-holder covering the middle back of human body from Dazhui (GV 14) to Yaoshu (GV 2) after paving a layer (about 1 cm thick) of fresh ginger in the holder, and then ignited, followed by the next moxa-cone, 3 cones altogether every time for each participant. The treatment was conducted once a week, 12 times in total. The subjects' constitution was scored according to the "Classification and Evaluation of Constitution of Traditional Chinese Medicine" formulated by China Association of Chinese Medicine. The serum ACTH and CORT contents were measured by radioimmunoassay before and at the end of the treatment and 6 months after the treatment. RESULTS: The constitation scores of the moxibustion group and control A group were significantly higher than that of the control B group before treatment (P0.05). The serum CORT and ACTH contents were significantly decreased in both the moxibustion and control A groups in comparison to the control B group before treatment (P0.05)．. CONCLUSION: The ginger-separated snake moxibustion treatment may improve the constitution of yang deficiency participants by increasing the levels of serum ACTH and CORT, which may be helpful in resisting diseases.
ABSTRACT
AIM: To observe the influence of gold nanoparticles combined with Endostar (AuNPs-Endostar) on the melanoma lung metastasis of mice and the underlying mechanism.METHODS: C57BL/6 mice (n=24) were selected for constructing the model of spontaneous lung metastasis of melanoma B16-F10 cells.Subsequently, the mice were randomly divided into Endostar group, AuNPs group, AuNPs-Endostar group and model group.After the formation of melanoma, the mice in each group were injected with different drugs through tail vein for 0.1 mL daily.After 9 d, the mice were narcotized for cutting the tumors in situ.After the operation, they were raised for 2 weeks before killed for obtaining the lung tissues to observe the situation of the metastasis.HE staining was utilized for observing the necrosis status of the tumors in situ, while immunostaining was applied for testing the expression of CD31, carbonic anhydrase-IX (CA-IX), vimentin and zonula occludens-1 (ZO-1) in the tumors.RESULTS: Compared with model group, the pulmonary metastasis in the groups with medical treatment was obviously reduced.In AuNPs-Endostar group, the metastasis inhibition rate was the highest, and the tumor necrosis was also decreased obviously, with the significant reduction of CD31, CA-IX and vimentin expression in the tumors and significant increase in ZO-1 expression.CONCLUSION: Compared with using Endostar or AuNPs alone, the combination of AuNPs with Endostar significantly improves the curative effect of inhibiting the pulmonary metastasis of melanoma in the mice.The mechanism may be related to reducing the tumor angiogenesis, norma-lizing the blood vessels and improving tumor hypoxia, thus inhibiting the tumor epithelial-mesenchymal transition, increasing the tight junctions between tumor cells and decreasing the invasiveness.

In the research community, resistance to apoptosis is often considered a hallmark of cancer. However, pathologists who diagnose cancer via microscope often see the opposite. Indeed, increased apoptosis and mitosis are usually observed simultaneously in cancerous lesions. Studies have shown that increased apoptosis is associated with cancer aggressiveness and poor clinical outcome. Furthermore, overexpression of Bcl-2, an antiapoptotic protein, is linked with better survival of cancer patients. Conversely, Bax, CD95, Caspase-3, and other apoptosis-inducing proteins have been found to promote carcinogenesis. This notion of the role of apoptosis in cancer is not new; cancer cells were found to be short-lived 88 years ago. Given these observations, resistance to apoptosis should not be considered a hallmark of cancer.
