Atherosclerosis(AS) is the key pathological basis of coronary heart disease(CHD), and lipid infiltration is a classical theory to explain the pathological mechanism of AS. The theory highlights that the occurrence and development of AS are closely related to abnormal lipid metabolism, with the essence of the pathological reaction caused by the invasion of lipids into arterial intima from plasma. Phlegm and blood stasis are physiologically homologous and subject to pathological co-existence. Phlegm-blood stasis correlation is the basic theory to explain the pathogenesis characteristics of CHD and has important guiding significance for revealing the mecha-nism of lipid infiltration of CHD. Phlegm is the pathological product of abnormal metabolism of Qi, blood, and body fluid, and a gene-ral summary of a series of abnormally expressed lipid substances. Among them, turbid phlegm invades the heart vessels, gradually accumulates, and condenses to achieve the qualitative change from "invisible pathogen" to "tangible pathogen", which corresponds to the mechanism of lipid migration and deposition in the intima of blood vessels, and is the starting factor of the disease. Blood stasis is the continuous development of phlegm, and it is a result of pathological states such as decreased blood fluidity, increased blood coagulation, and abnormal rheology. The fact that blood stasis caused by phlegm accords with the pathological process of "lipid abnormality-circulatory disturbance" and is the central link of the disease. Phlegm and blood stasis aggravate each other and lead to indissoluble cementation. The phlegm-blood stasis combination serves as common pathogen to trigger the disease, which is the inevitable outcome of the disease. Based on the phlegm-blood stasis correlation theory, the simultaneous treatment of phlegm and blood stasis is established. It is found that this therapy can simultaneously regulate blood lipid, reduce blood viscosity, and improve blood circulation, which can fundamentally cut off the biological material basis of the reciprocal transformation between phlegm and blood stasis, thus exerting a significant curative effect.

OBJECTIVE: To study effects of Shenmai Injection on hypertensive heart failure and its mechanism for inhibiting myocardial fibrosis. METHODS: Salt-sensitive (Dahl/SS) rats were fed with normal diet (0.3% NaCl) and the high-salt diet (8% NaCl) to observe the changes in blood pressure and heart function, as the control group and the model group. Salt-insensitive rats (SS-13BN) were fed with the high-salt diet (8% NaCl) as the negative control group. After modeling, the model rats were randomly divided into heart failure (HF) group, Shenmai Injection (SMI) group and pirfenidone (PFD) group by a random number table, with 6 rats in each group. They were given sterilized water, SMI and pirfenidone, respectively. Blood pressure, cardiac function, fibrosis and related molecular expression were detected by sphygmomanometer, echocardiogram, enzyme linked immunosorbent assay (ELISA), hematoxylin-eosin staining, Masson staining, immunofluorescence and qPCR analysis. RESULTS: After high-salt feeding, compared with the control and negative control group, in the model group the blood pressure increased significantly, the left ventricular ejection fraction (LVEF) and left ventricular fraction shortening (LVFS) were significantly reduced, and the serum NT-proBNP concentration increased significantly (all P<0.05); furthermore, the arrangement of myocardial cells was disordered, the edema was severe, and the degree of myocardial fibrosis was also significantly increased (P<0.05); the protein and mRNA expressions of collagen type I (Col I) were up-regulated (P<0.05), and the mRNA expressions of transforming growth factor β 1 (TGF- β 1), Smad2 and Smad3 were significantly up-regulated (P<0.05). Compared with HF group, after intervention of Shenmai Injection, LVEF and LVFS increased, myocardial morphology was improved, collagen volume fraction decreased significantly (P<0.05), and the mRNA expressions of Col I, TGF- β 1, Smad2 and Smad3, as well as Col I protein expression, were all significantly down-regulated (all P<0.05). CONCLUSION Myocardial fibrosis is the main pathological manifestation of hypertensive heart failure, and Shenmai Injection could inhibit myocardial fibrosis and effectively improve heart failure by regulating TGF-β 1/Smad signaling pathway.

Objective: To evaluate the effect of postoperative radiotherapy and high-risk pathological factors on the prognosis of early-stage neuroendocrine carcinoma of cervix (NECC). Methods: A single-center retrospective cohort study of early-stage NECC in Peking Union Medical College Hospital from January 2011 to April 2022 were enrolled. The patients were treated with radical hysterectomy±adjuvant treatment. They were divided into postoperative non-radiation group and postoperative radiation group. The possible postoperative recurrence risk factors identified by univariate analysis were assessed using multivariate logistic regression. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate. Results: (1) Sixty-two cases were included in the study, including 33 cases in postoperative non-radiation group and 29 cases in postoperative radiation group. (2) The median follow-up time was 37 months (ranged 12-116 months), with 23 cases (37%) experienced recurrences. There were 7 cases (11%) pelvic recurrences and 20 cases (32%) distant recurrences, in which including 4 cases (6%) both pelvic and distant recurrences. Compared with postoperative non-radiation group, the postoperative radiation group had a lower pelvic recurrence rate (18% vs 3%; P=0.074) but without statistic difference, a slightly elevated distant recurrence rate (24% vs 41%; P=0.150) and overall recurrence rate (33% vs 41%; P=0.513) without statistically significances. Univariate analysis showed that lymph-vascular space invasion and the depth of cervical stromal invasion≥1/2 were risk factors for postoperative recurrence (all P<0.05). Multivariate analysis showed lymph-vascular space invasion was an independent predictor for postoperative recurrence (OR=23.03, 95%CI: 3.55-149.39, P=0.001). (3) During the follow-up period, 18 cases (29%, 18/62) died with tumor, with 10 cases (30%, 10/33) in postoperative non-radiation group and 8 cases (28%, 8/29) in postoperative radiation group, without significant difference (P=0.814). The postoperative 3-year and 5-year survival rate was 79.2%, 60.8%. The depth of cervical stromal invasion≥1/2 was more common in postoperative radiation group (27% vs 64%; P=0.011), and postoperative radiation in such patients showed an extended trend in PFS (32.3 vs 53.9 months) and OS (39.4 vs 73.4 months) but without statistic differences (P=0.704, P=0.371). Compared with postoperative non-radiation group, the postoperative radiation did not improve PFS (54.5 vs 37.3 months; P=0.860) and OS (56.2 vs 62.4 months; P=0.550) in patients with lymph-vascular space invasion. Conclusions: Postoperative radiation in early-stage NECC patients has a trend to reduce pelvic recurrence but not appear to decrease distant recurrence and overall recurrence, and has not improved mortality. For patients with the depth of cervical stromal invasion≥1/2, postoperative radiation has a trend of prolonging OS and PFS but without statistic difference. Lymph-vascular space invasion is an independent predictor for postoperative recurrence, but postoperative radiation in such patients does not seem to have any survival benefits.

This study investigated the effects of Xuefu Zhuyu Decoction on myocardial metabolites in a rat model of coronary heart disease with heart blood stasis syndrome and explored the therapeutic mechanism of blood circulation-promoting and blood stasis-removing therapy. SD rats were randomly divided into a sham operation group, a model group, a Xuefu Zhuyu Decoction group(14.04 g·kg~(-1)), and a trimetazidine group(5.4 mg·kg~(-1)). The sham operation group underwent thread insertion without ligation, while the other groups underwent coronary artery left anterior descending branch ligation to induce a model of coronary heart disease with heart blood stasis syndrome. Three days after modeling, drug intervention was performed, and samples were taken after 14 days of intervention. General conditions were observed, and electrocardiogram and cardiac ultrasound indices were measured. Hematoxylin-eosin(HE) staining and Masson staining were used to observe tissue pathological morphology. The enzyme linked immunosorbent assay(ELISA) was used to measure the levels of triglyceride(TG) and total cholesterol(TC) in the serum. Ultra high performance liquid chromatography-quantitative exactive-mass spectrometry(UHPLC-QE-MS) technology was used to screen differential metabolites in myocardial tissue and conduct metabolic pathway enrichment analysis. The results showed that Xuefu Zhuyu Decoction significantly improved the general condition of the model rats, reduced heart rate and ST segment elevation in the electrocardiogram, increased left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(LVFS), and decreased left ventricular internal diameter in diastole(LVIDd) and left ventricular internal diameter in systole(LVIDs). HE staining and Masson staining showed that Xuefu Zhuyu Decoction effectively alleviated myocardial tissue structural disorders, inflammatory cell infiltration, and collagen fiber deposition in the model rats. ELISA results showed that Xuefu Zhuyu Decoction effectively regulated serum TG and TC levels in the model rats. There were significant differences in the metabolic phenotypes of myocardial samples in each group. Fourteen differential metabolites were identified in the Xuefu Zhuyu Decoction group, involving five metabolic pathways, including arginine and proline metabolism, glycerophospholipid metabolism, aminoacyl-tRNA biosynthesis, ether lipid metabolism, and alanine, aspartate, and glutamate metabolism. Xuefu Zhuyu Decoction improved cardiac function and myocardial structural damage in the rat model of coronary heart disease with heart blood stasis syndrome, and its biological mechanism involved the regulation of lipid metabolism, choline metabolism, amino acid metabolism, energy metabolism, and protein synthesis pathways.

Depression syndromes(anxiety and depression), as typical psychological disorders, often coexist with and mutually influence coronary heart disease(CHD). They constitute a psycho-cardiology disease involving both the blood vessels of the heart and the spirit of the heart. Based on the theory of "coexistence of diseases and depression syndromes", it was proposed that CHD and depression syndromes coexisted independently and were causally related. The factors of depression syndromes go through the entire course of CHD and have different causal relationships at different stages, leading to a pathogenic process of "depression causing disease" or "disease causing depression". In the chronic latent period, phlegm predominates, with depression leading to the production of phlegm. Phlegm accumulation and Qi stagnation initiate a mutual damage process of psycho-cardiology, marking the onset of the disease. In the pathological development period, blood stasis becomes predominant. Depression leads to blood stasis, which further obstructs Qi circulation, accelerating disease progression. In the acute attack period, toxicity becomes crucial. Depression transforms into toxicity, damaging Qi and blood, disturbing the balance of the mind, and inducing a sudden and severe exacerbation of the disease. Based on this, the approach of treating phlegm and depression together, treating blood stasis and depression together, and treating toxicity and depression together by stages was established. Research has found that this approach can simultaneously improve organic damage and emotional disorders, and also has a regulating effect on micro-level syndrome indicators, achieving harmonization of psycho-cardiology in the treatment.

Golgi protein 73 (GP73) is a transmembrane protein on the Golgi apparatus and can be cut and released into the blood. In recent years, an increasing number of clinical studies have shown that the elevated serum GP73 level is closely related to liver diseases. And thus GP73 is expected to be used as a new serum marker for assessing progress of chronic liver diseases. Herein, the clinical application of serum GP73 in chronic hepatitis, liver fibrosis, liver cirrhosis and hepatocellular carcinoma with different etiologies was reviewed based on available literatures; and a research outlook in this field is made.

Objective: To investigate the factors affecting the success of conversion therapy in patients with initially unresectable colorectal cancer liver metastases (CRLM) in order to provide evidence-based medical evidence for formulating individualized treatment strategies for patients. Methods: A retrospective case-control study was used in this study. Clinical data of 232 patients with initially unresectable CRLM receiving first-line systemic treatment in Sun Yat-sen University Cancer Center from January 2013 to January 2020 were collected, including 98 patients of successful conversion and 134 patients of failed conversion as control. Conversion therapy scheme: 38 patients received FOLFOXIRI regimen chemotherapy (irinotecan, oxaliplatin, calcium folinate and fluorouracil), 152 patients received FOLFOX regimen (oxaliplatin, calcium folinate and fluorouracil), 19 patients received FOLRIRI regimen (irinotecan, calcium folinate and fluorouracil), 23 patients received systemic chemotherapy combined with fluorouridine hepatic artery infusion chemotherapy; 168 patients received targeted therapy, including 68 of bevacizumab and 100 of cetuximab. Logistics analysis was used to compare the factors affecting the success of conversion therapy. The Kaplan-Meier method was used to calculate progression-free survival (PFS), and the Log-rank test was used for survival comparison. Results: Among 232 patients, 98 patients had successful conversions and 134 patients had failed conversions with a successful conversion rate of 42.2%, meanwhile 30 patients underwent simple hepatectomy and 68 underwent hepatectomy combined with intraoperative radiofrequency ablation. After first-line chemotherapy, 111 patients (47.8%) were partial remission, 57 patients (24.6%) were stable disease, and 64 patients (27.6%) were progression disease. During the median follow-up of 18.8 (1.0-87.9) months, 148 patients were dead or with tumor progression. The median PFS time of patients with successful conversion was longer than that of patients with failed conversion (31.0 months vs. 9.9 months, P<0.001). Univariate analysis found that the bilobar distribution of liver tumors (P=0.003), elevated baseline carcinoembryonic antigen (CEA) levels (P=0.024), tumor invasion of the portal vein (P=0.001), number of metastatic tumor>8 (P<0.001), non-FOLFOXIRI (P=0.005), and no targeted therapy (P=0.038) were high risk factors for the failed conversion therapy. The results of multivariate logistics analysis indicated that the number of metastatic tumor >8 (OR=2.422, 95%CI: 1.291-4.544, P=0.006), portal vein invasion (OR=2.727, 95%CI: 1.237-4.170, P=0.008) were the independent risk factors for failed conversion therapy, while FOLFOXIRI regimen (OR=0.300, 95%CI: 0.135-0.666, P=0.003) and targeted drugs (OR=0.411, 95%CI: 0.209-0.809, P=0.010) were independent protective factors for successful conversion therapy. Conclusions: The number of metastatic tumor and portal vein invasion are key factors that affect the outcomes of conversion therapy for initially unresectable CRLM. If a patient can tolerate chemotherapy, a combination program of three-drug and targeted therapy is preferred for the active conversion therapy.

Chronic heart failure is a serious heart disease with dyspnea and limited activity tolerance as the main clinical manifestations. Autophagy is a self-protection mechanism in eukaryotic cells and plays an important role in the development of heart failure. Appropriately increasing the level of autophagy during the compensated stage of heart failure and timely removal of necrotic myocardial organelles and other harmful garbage can inhibit myocardial hypertrophy to a certain extent，alleviate myocardial remodeling，and delay heart failure. The theory of healthy Qi and pathogenic Qi is an important basic theory for explaining the occurrence of diseases，and struggle between healthy Qi and pathogenic Qi exists in the entire onset of chronic heart failure，which may lead to pathogenic Qi invasion and healthy Qi deficiency. The regulatory effect of autophagy on cardiomyocytes is similar to the theory of healthy Qi and pathogenic Qi in traditional Chinese medicine （TCM）. Autophagy is the body's self-regulatory mechanism for healthy Qi and pathogenic Qi in a dose-effect manner，Specifically，autophagy can only protect the body's cells to a certain extent，and healthy Qi can only take effect within a certain range and degree. To protect the body from external pathogenic factors，excessive or insufficient autophagy may destroy the stability of the body's environment. In this regard，we use the theory of healthy Qi and pathogenic Qi as a starting point to clarify the function of autophagy in the development of chronic heart failure from a macro and micro perspective，and propose adjusting the balance of healthy Qi and pathogenic Qi in the body to regulate the autophagy of cardiomyocytes. The principle of prevention and treatment is expected to lay the foundation for modern research on the function of autophagy in the development of chronic heart failure in TCM，find novel therapy for chronic heart failure at different stages，and provide new insights into the diagnosis and treatment of chronic heart failure.
