There are some major changes win the revised 2016 WHO Classification of Lymphoid Neoplasms.Based on the clinicopathological changes and genetic/molecular findings in the past years,the new classification clarified the diagnosis and clinical management of some very early stages of lymphoproliferative disorders,refined the diagnostic criteria for some lymphoid neoplasms,and further emphasized the significance of genetic/molecular studies in the diagnosis and clinical treatment of lymphomas.A small number of new provisional entities were added to the 2016 edition.

Objective To investigate the predictive value of epicardial adipose tissue(EAT) thickness for the recurrence of atrial fibrillation (RAF) after concomitant valve replacement and bipolar radiofrequency ablation.Methods From January 2012 to May 2014,156 patients with permanent atrial fibrillation and organic valvular diseases underwent concomitant valve replacement and successful bipolar radiofrequency ablation in the First People's Hospital of Shangqiu.After 1 year of follow-up,the recurrence of AF was analyzed and the correlation factors were analyzed statistically.Results All patients completed a regular follow-up.During a 12-month follow-up period,RAF was observed in 39 patients (25.0％).Echocardiography-derived regional EAT thickness was significantly greater in RAF patients than that in non-RAF patients((6.9±0.6) mm vs.(5.5±0.7) mm,t=4.649,P＜0.05).The EAT thickness strongly correlated with patients age,body mass index,Ratio of left atrial diameter,mitral diastolic blood flow velocity and early diastolic velocity of mitral annulus,low density lipoprotein-cholesterol and thyroglobulin (r =0.62,0.57,0.68,0.59,0.73,0.76;P ＜ 0.05).Cox multivariable analysis showed that,duration of AF history (95％CI:1.01-1.15,P =0.040),left atrial diameter (95％CI:1.07-1.24,P =0.021) and EAT thickness (95％CI:1.05-1.79,P =0.009) were independent predictors of RAF.Conclusion Echocardiography-derived regional EAT thickness combined with left atrial diameter may serve as effective parameters in identifying patients at the highest risk for RAF.

Oxidative stress and inflammation are two main factors in the progress of diabetic nephropathy(DN) and its complications. NF‐E2 p45‐related factor (Nrf2) is a crucial transcriptional factor which manipulates downstream genes that encode some antioxidant enzymes and phase Ⅱ detoxifying enzymes ,to maintain the redox homeostasis and cellular detoxification response. Therefore ,more and more researchers are focusing on the role of Nrf2 in DN. In this review ,the detailed role of Nrf2 in DN will be discussed. Hopefully ,our work can epitomize recent research progress and provide novel clues for diabetic nephropathy prevention and treatment.

Objective To review the outcome of coronary artery bypass graft (CABG) using left internal thoracic artery grafts in the patients aged over 70 years old.Methods Two hundred and eighty-eight patients aged over 70 years old from January 2009 to January 2014 who underwent CABG were selected.All of the patients were divided into two groups on base of the graft:control group:only saphenous vein graft was used in 138 cases; observation group:the left internal thoracic artery to the left anterior descending artery was used in 150 cases,which also included total arterial grafting,facilitated by the use of the radial artery,right gastroepiploic artery was operated in 7 cases,beside these artery grafts,saphenous vein graft was used to anastomosis with other vessels.Results Operative mortality was 2.9％ (4/138) in control group and 2.0％ (3/150) in observation group,and there was no significance (P ＞ 0.05).The volume of blood drainage was larger in observation group [(796.2 ± 382.4) ml] than that in control group [(512.8 ± 387.5) ml],and there was significant difference (P ＜ 0.05).At the same time,there was no significant difference in the incidence rate of second thoractomy,malignant arrhythmia,stroke,poor wound healing,and usage of intraaortic balloon counterpulsation between two groups (P ＞ 0.05).Conclusion It does not increase the mortality and incidence of serious complications using the left internal thoracic artery to the left anterior descending artery in the patients aged over 70 years old during CABG.

Tumor vaccine is one of the most promising therapeutic strategies in tumor immunotherapy. It promotes the antigen presentation process by delivering tumor antigen and then activates the anti-tumor immune response. As a new class of vaccines, messenger RNA (mRNA) vaccines can activate the immune system to achieve the purpose of immunotherapy by delivering the mRNA sequence of a specific antigen into the body and expressing the corresponding antigen protein. Compared with traditional vaccines, mRNA vaccines have the advantages of a short production cycle, high effectiveness, and strong immunogenicity. In recent years, the application of mRNA vaccines in tumor immunotherapy has attracted widespread attention, but the instability and low delivery efficiency of mRNA limit its application. Nano delivery system can effectively solve the problem of mRNA vaccine delivery, greatly promote the research process and clinical application of mRNA tumor vaccines, and has become a hot spot in the research of mRNA vaccines. In this review, we introduced the mRNA tumor vaccines, focusing on the application of nano delivery system in mRNA tumor vaccines, in order to provide new ideas and new methods for the efficient delivery of mRNA tumor vaccines and tumor immunotherapy.

The serum manganese, chromium, zinc and copper levels of 63 cases with coronary heart disease and 33 normals were determined by the inductively couple plasma emission spectroscopy. The concentrations of Mn, Cr, Zn and Cu were 0.02145 ?0.0107 ppm, 0.0230 ?0.0167 PPm, 0.905?0.278 ppm 1.056 ?0.404 PPm and the Cu/Zn ratio was 0.973 ?0.395 in normals.In comparing with normals, a significant increase in the serum zinc concentration (P

The scientificalness of traditional Chinese medicine (TCM) is often doubted and criticized for the record in Huangdi Neijing that the liver is located in the left of the human body. The most popular explanation of this criticism is that the conception of zang-fu viscera in TCM is quite different from which defined in Western medicine. It means that the zang-fu viscera in TCM are not exactly the corresponding anatomical organs in modern human anatomy but reflect the functions of some systems in human body. According to the classical theories of TCM in Huangdi Neijing, we consider that the record of liver located in the left of the human body is based on the Ba Gua (Eight Diagrams) of traditional Chinese philosophy, not the human anatomy. In brief, the conception of zang-fu viscera is initially a gross anatomical conception, and in a sense the anatomic sites and functions of which are mostly similar to those described in Western medicine.

The ancient theory and technology which are related to preventive treatment of disease by dietetic regulation and coordinating meridian according to 25 tones have been developed in the early 21st century. It is proved in sonocytology by nanotechnology that cells are able to produce noise, and the noise will change at first when the cells have any disorders. This theory is in accordance with the one in Huangdi Neijing. The nanotechnology can be introduced into the basic research of traditional Chinese medicine and may contribute to the modernization of traditional Chinese medicine.

Objective To develop a method for the determination of four saponins of panax notoginseng in Compound Dan-shen Prescription (CDP) by HPLC. Methods The conditions for the experiment were: determination of notoginsenoside R1, ginsenoside Rg1 and ginsenoside Re with acetonitrile - 0. 05 % phosphoric acid (19 : 81) as mobile phase and the detection wave at 203nm, determination of ginsenoside Rb1 with acetonitrile - water (33 : 67) as mobile phase and the detection wave at 203nm. Results A good linearity for notoginsenoside R1 was in the range of 0. 24 ~ 3. 6?g ( r = 0. 9997), 1. 2 ~ 18?g (r = 0. 9994) for ginsenoside Rg1, 0. 08 ~ 1. 2?g(r = 0. 9997) for ginsenoside Re and 0. 25-3. 72?g (r = 0. 9998) for ginsenoside Rb1. The stability of the four saponins is well kept at 4℃ for four months. Conclusion This method is simple, rapid, accurate and with good reproducibility and can be used for the quality control of CDP.

Bone metastasis is a common complication in patients with malignant carcinoma. This process involves interactions between metastatic cancer cells and bone microenvironment. The two common pathological types are osteolytic and osteoblastic metastasis. Damage to the bone is closely associated with tumor growth.
