Objective:To explore the molecular mechanism of the effect of the histone methylase zeste gene enhancer homolog 2 (EZH2) on the proliferation and apoptosis of human hypertrophic cardiomyocytes AC16.Methods:The AC16 hypertrophic cardiomyocyte model was constructed by adding angiotensin Ⅱ to the AC16 cell culture medium. The cells were divided into four groups, including the blank control group, the angiotensin Ⅱ group, the empty vector + angiotensin Ⅱ group, and the EZH2 overexpression + angiotensin Ⅱ group. The expression levels of EZH2 and brain natriuretic peptide ( BNP) genes were measured using fluorescent quantitative PCR. The EZH2, trimethylation of lysine at position 27 of histone H3 (H3K27me3), and BNP proteins expression were detected by Western Blot. The MTS method was used to detect the proliferation of AC16 cell. The Annexin V-FITC/PI double staining method was used to detect the apoptosis of AC16 cell. Results:Compared with the blank control group, the expression levels of EZH2 and H3K27me3 in the angiotensin Ⅱ group were decreased, the expression level of BNP was increased, cell proliferation was decreased, and apoptosis was increased (all P < 0.001). Compared with the empty vector + angiotensin Ⅱ group, the expression levels of EZH2 and H3K27me3 in the EZH2 overexpression + angiotensin Ⅱ group were increased, the expression level of BNP was decreased, the cell proliferation level was increased, and the apoptosis level was decreased (all P < 0.001). There was no significant difference between the angiotensin Ⅱ group and the empty vector + angiotensin Ⅱ group (all P > 0.05). Conclusions:Histone methylase EZH2 has an effect on the proliferation and apoptosis of AC16 cell, providing a reference for the treatment of myocardial hypertrophy and revealing the exact pathogenesis of myocardial hypertrophy.

Objective:To explore the influence of mindfulness on perceived stress in psychiatric nurses and the mediating effect of resilience.Methods:A total of 427 psychiatric nurses from a psychiatric hospital in Beijing were selected.Five-facet mindfulness questionnaire(FFMQ), Chinese-version perceived stress scale (CPSS) and Connor-Davidson resilience scale (CD-RISC) were used in this survey.Pearson correlation analysis and multiple stepwise regression analysis were performed using SPSS 24.0.And mediating effect was performed using AMOS 24.0.Results:The total score of psychiatric nurses' perceived stress was (37.89±7.16). Among all psychiatric nurses, 66.74% were under high pressure and 20.84% were under great pressure.The perceived stress was negatively correlated with mindfulness(123.69±10.82, r=-0.65, P<0.01) and resilience(85.40±17.87, r=-0.67, P<0.01), and mindfulness was positively correlated with resilience ( r=0.50, P<0.01). The direct effect of mindfulness on perceived stress was -0.15, the indirect effect was -0.34, and the total effect was -0.49. Conclusion:Resilience plays a partial mediating role between mindfulness and perceived stress psychiatric nurses.

Objective:To investigate the microenvironment associated with tumorimmunity in regenerated lymph nodes treated with VEGF-C, which involves the lymphangiogenesis, chemokine as well as alteration of cell populations.Methods:A total of 10 nude mice were randomized to 2 groups. 5 mice in group A were treated with autologous lymph nodes fragmentary transplantation together with VEGF-C, 5 mice without any intervention in group B were served as control group. 4 weeks after surgeries, MDA-MB-231-Luc-GFP cells (5×10 6 cells/mouse, 100 μl of 40% matrigel solution) were injected subcutaneously in the thoracic flunk of nude mice in group A, the same number cells were implanted into the second mammary fat pad in group B as well. 4 weeks post inoculation, the tumor draining lymph nodes (TDLNs) in both groups were harvested, and the microenvironment was assessed by hematoxylin-eosin (HE) staining and multispectral immunofluorescence staining for LYVE-1, chemokine CCL21, programmed death ligand-1(PD-L1) and F4/80. Results:The specific markers were analyzed based on positive cell percentage between group A and group B. The LYVE-1 and F4/80 expression in the group A was significantly higher than that in group B[LYVE-1: group A 21.44 0(34.675)% vs group B 2.964 (4.160)%, P<0.001; F4/80: group A 5.396 (7.205)% vs group B 3.573 (2.670)%, P=0.020)], and there were no significant differences in the expression of CCL21 and PD-L1 between these two groups [CCL21: group A 21.470((29.145)% vs group B 16.430((29.145)%( P=0.166); PD-L1: group A10.000 (14.430)%vs group B 4.070 (26.740)%, P=0.091]. Additionally, the double positive expression of LYVE-1/CCL21 and LYVE-1/F4/80 had still statistically significant differences[LYVE-1/CCL21: group A 8.637 (13.150)% vs group B 1.571 (1.680)%, P<0.001; LYVE-1/F4/80: group A 6.181 (9.050)% vs group B 1.454 (0.830)%, P<0.001], whereas, the two groups did not differ from each other in the double positive expression of LYVE-1/PD-L1 [group A 3.617 (4.195)% vs group B 2.363 (3.900)%, P=0.266]. Conclusions:The renewed lymph nodes treated with VEGF-C demonstrate some more immune suppressive conditions such as lymphatic endothelial cells hyperplasia, myeloid-derived suppressor cells infiltration, enhanced expression of CCL21 and PD-L1.

OBJECTIVE： To synthetize the synthesis of mitoxantrone and evaluate its quality. METHODS： Crude product of mitoxantrone was prepared by slow oxidation of 1，4，5，8-tetrahydro-anthraquinone with N-（2-hydroxyethyl） ethylenediamine in water bath at 50 ℃ for 2 h under argon protection and in dry air for 4 h. The crude product was crystallized by ethanol-n-hexane  （4 ∶ 1，V/V） mixture solution， which was cooled overnight and then washed by ethanol-n-hexane mixture for many times. The melting range， pH value of solution， ultraviolet-visible absorption spectrum， infrared structural characteristics， drying weight loss （water loss rate） and critical relative humidity （CRH） of the purified products （4 batches） were investigated. HPLC method was used to determine the contents of mitoxantrone. RESULTS： The mitoxantrone was prepared successfully， and synthetic yield of mitoxantrone was 34.3％； the melting point ranged from 159.1-163.6 ℃. The aqueous solution was alkaline （pH 7.63-9.54）； there was a maximum ultraviolet absorption peak at 235-245 nm； there was a maximum absorption peak of visible light at 590-600 nm； the infrared characteristics were consistent with those described of mitoxantrone in the 2015 edition of the Infrared Spectrum Collection of Drugs； water loss rate were －0.83％-2.36％； CRH value was 54.7％， and the average content of the product was 78.1％（n＝4） by HPLC method. CONCLUSIONS： The mitoxantrone is synthesized under mild， non-toxic and harmless experiment conditions. The synthesis step is simple， the cost is low and the yield is high. The quality of products meets the quality requirements.

Objective: Autologous lymph nodes fragmentary transplantation combined with vascular endothelial growth factor-C (VEGF-C) on athymic nude mice to explore the association between regeneration of lymphatic vessel and tumor cell migration. Methods: A total of 45 nude mice were randomly divided into 3 groups: Group A, simple autologous lymph nodes fragmentary transplantation, n=15; Group B, autologous lymph nodes fragmentary transplantation together with VEGF-C, n=15; Group C, without any intervention, n=15. At 1 month, 2 months and 6months after surgeries, the axillary lymph nodes of 5 mice in each group were dynamically examined by in vivo indocyanine green (ICG) fluorescence imaging respectively. The regenerated lymph nodes and relevant skin were evaluated using hematoxylin-eosin (H&E) staining and the skin was quantitatively analyzed via immunofluorescence staining for lymphatic vessel endothelial hyaluronan receptor 1(LYVE-1) as well. Results: One month after surgery, the right regenerated axillary lymph nodes in group B (5/5) were visible by in vivo ICG fluorescence imaging, whereas the same signals were not detected in group A (0/5). The results were the same at 2 and 6 months after surgery. HE staining showed that the cortical, paracortical, and medullary regions of the right axillary lymph nodes of the experimental group B were clear, and the lymphatic vessel structure was present, accompanied by lymphocyte infiltration. Immunofluorescence staining of the right upper limb showed that the expression of LYVE-1 in the lymphatic endothelium of the B group was significantly higher than that in group A (P<0.001) and the control group (both P<0.001). Conclusions Due to the promising consequence of regenerated lymph nodes, the procedure of autologous lymph nodes fragmentary transplantation combined with VEGF-C in athymic nude mice provides a reliable animal model for the next stage research.

OBJECTIVE: To review the development of adult and pediatric liver transplantation in Tianjin First Center Hospital, and to enhance academic exchanges, improve technological innovation, and jointly promote the progress and maturity in the field of liver transplantation. METHODS: The development of liver transplantation in Tianjin First Center Hospital was analyzed. The clinical data of adult and pediatric liver transplantation from September 1998 to September 2018 were collected. The important events and technological innovation achievements of liver transplantation during the 20 years were summarized. RESULTS: The first clinical liver transplantation was attempted in Tianjin First Central Hospital in April 1980. The first long-term survival adult liver transplantation in China was completed in 1994 (11 years survival after the operation). The specialized team of liver transplantation was formally established in September 1998. The 20-year clinical exploration and progress reflected the characteristics of era changes and technological innovation during the rapid development of liver transplantation in China. Our center performed liver re-transplantation in January 1999, reduced-size pediatric liver transplantation in August 2000. In May 2001, we organized the formulation for the preventive and treatment plan for hepatitis B recurrence after liver transplantation. We performed combined liver and kidney transplantation in July 2002, split liver transplantation (SLT) in April 2004, the first domino liver transplantation (DLT) in August 2005. Pediatric living donor liver transplantation (LDLT) was initiated in October 2006, adult LDLT was carried out in August 2007. In September 2007, the first living donor combined liver and kidney transplantation from the same donor in Asia was performed. The first domino+living donor double grafts liver transplantation in the world was performed in January 2009. In March 2011, we performed laparoscopically assisted right hepatic lobe liver transplantation (LDLT) with middle hepatic vein. In May 2014, living donor laparoscopic left lateral lobe procurement was successfully established. In April 2016, simultaneous liver, pancreas and kidney multi-organ transplantation was completed. Domino donor-auxiliary liver transplantation was performed in February 2017. In December 2017, extracorporeal membrane oxygenation (ECMO)-supported liver transplantation in a patient with severe pulmonary hypertension was successfully completed. Liver transplantation combined with partial splenectomy was established in April 2018. Cross-domino liver transplantation (hypersensitive kidney transplantation with auxiliary liver transplantation+pediatric liver transplantation) was performed in May 2018. During the 20 years, the team has performed or assisted other centers in Beijing, Shanghai, Guangzhou and Shenzhen to carry out more than 10 000 cases of liver transplantations. A total of 7 043 cases of various types of liver transplantation were performed in the single center of the hospital (6 005 adult liver transplantations and 1 038 pediatric liver transplantations). Concerning adult liver transplantation, the cumulative 1-year, 3-year and 5-year survival rate from September 1998 to March 2003 were 83.1%, 73.0% and 69.0%, from April 2003 to March 2009 were 85.3%, 76.2% and 72.1% and from April 2009 to September 2018 were 87.5%, 79.2% and 75.1%, respectively. The cumulative 1-year, 3-year and 5-year survival rate for pediatric liver transplantation were 93.5%, 92.2% and 90.2%, respectively. The nucleoside (acid) analogue combined with low dose hepatitis B immunoglobulin (HBIG) was developed to prevent the recurrence of hepatitis B after liver transplantation, this plan has reduced the recurrence rate of hepatitis B and the 5-year re-infection rate of hepatitis B virus (HBV) after liver transplantation significantly. The risk assessment system for tumor recurrence after liver transplantation was established and individual treatment method was established based on this assessment system. Continuous exploration and improvement of liver transplantation for liver cancer, liver re-transplantation, liver transplantation with portal vein thrombosis, SLT, DLT and multi-organ combined transplantation have significantly improved the clinical efficacy of patients and the post-operative survival rate. CONCLUSIONS The liver transplantation team of Tianjin First Center Hospital has carried out a scientific and technological exploration on the key problems and technical difficulties of clinical liver transplantation. This work strongly has initiated and promoted the rapid development of liver transplantation in China. The restrictive barrier of hepatitis B recurrence after liver transplantation has been overcome. The risk prevention and control system of tumor recurrence after liver transplantation has been established. A series of innovative achievements that can be popularized have been achieved in the field of complex liver transplantation and expansion of donor liver source. The iterative progress and sustainable development of liver transplantation have been realized.
