Lymphoma is a malignancy of mature lymphocytes. Signalling through the B cell receptor ( BCR ) is central to the development and maintenance of B cells. In light of the numer-ous proliferative and survival pathways activated downstream of the BCR, it comes as no surprise that malignant B cells would co-opt this receptor to promote their own growth and survival. Compounds that inhibit various components of this pathway, in-cluding spleen tyrosine kinase(Syk), Bruton’s tyrosine kinase (Btk), and phosphoinositol-3 kinase(PI3K), have been devel-oped. In this paper,the B-cell receptor signaling and its targeted inhibitors of lymphoid malignancies are reviewed.

Macrophages,as an important member of innate immune system,constitute a major component of the microenvironment of tumours,and play an important role in the occurrence and development of tumor.According to particular phenotypes and functions,macrophages can be divided into M1 macrophages and M2 macrophages.In the research of breast cancer,lung cancer,gynecological malignancies,researchers have found that tumor-associated macrophage has the similar phenotype and function of M2 macrophages.Tumor-associated macrophage can promote the formation of new blood vessels and lymphatic vessels in tumor tissue,thus contributing to the occurrence and development of tumor.The relation between tumor-associated macrophage and poor prognosis was also be found.The tumor microenvironment can affect the phenotype and function of macrophages,such as TGF,IL-10 and PGE-2.This paper reviewed the role and mechanism of macrophages in the tumorigenesis.

Objective To explore surgical options and clinical outcome of preperitoneal hernia repair (TAPP) and totally ext raperitoneal hernia repair (TEP) in inguinal hernia repair.Methods The clinical data of 302 patients underwent laparoscopic herniorrhaphy were retrospectively analyzed.Results None of patient s was changed to open operation.The TAPP and TEP outcome measures:the unilateral hernia surgery time from (31.2 ± 8.3) min and (55.3 ± 15.2) min,bilateral hernia surgery time was (46.2 ± 11.2)min and (80.2 ± 23.2) min; blood loss was (6.4 ± 2.0) ml and (7.2 ± 1.6) ml,bed activity for the first was (16.0 ± 1.8) h and (16.0 ± 1.5) h,hospital stay was (3.0 ±0.6) d and (3.1 ±0.8) d.Conclusions Laparoscope herniorrhaphy is safe due to lower recurrence and complications.It also has the advantages of slight pain and rapid recovery.

BACKGROUND: Diabetic cardiomyopathy, a serious complication of diabetes, is an important factor of increased mortality in patients with diabetes. Therefore, providing an effective experimental animal model is particularly important for studying the pathogenesis and treatment methods of diabetic cardiomyopathy. OBJECTIVE:To explore the method of establishing Wistar rat models of diabetic cardiomyopathy. METHODS:Forty rats were randomly divided into the control group (n=10) and diabetic cardiomyopathy group (n=30). The rats in the diabetic cardiomyopathy group were intraperitonealy injected with 60 mg/kg streptozotocin at a time to establish rat models of diabetic cardiomyopathy. The rats in the control group were given the same dosage of citric acid buffer by the same way. The rats in these two groups were al fed with non-fat high-sugar normal diet. RESULTS AND CONCLUSION:Compared with the control group, after 3 weeks of injection with streptozotocinin in rat models of diabetic cardiomyopathy, blood glucose level was significantly increased, myocardial cels arranged in disorder, the nuclei were of different sizes, colagen content in the myocardial tissue was significantly increased, and colagen fibers were thick and disordered. In addition, the mRNA and protein levels of transforming growth factorβ1 and type I colagen, two indices reflecting myocardial fibrosis, were markedly increased. These results indicate that intraperitonealy injecting large doses of streptozotocin (60 mg/kg) at a time and feeding with non-fat high-sugar normal diet could establish a stable rat model of type 1 diabetic cardiomyopathy. This method is safe and effective with high feasibility.

Objective To investigate the effects of inositol hexaphosphate (IP6) on proliferation of human osteosarcoma cell line MG-63 and primary cultured osteoblasts so as to explore the optimal concentration for achieving anti-cancer effects.Methods We primary cultured and identified human osteoblasts.Then we made recovery and normal culture of human osteosarcoma cell line MG-63.We tested the proliferation of two kinds of cell lines under different concentrations of IP6 by MTT to determine the optimal concentration and then detected MG-63 cell cycle and apoptosis by flow cytometry.Results When IP6 concentration was more than 1 mmol/L,IP6 began to inhibit the proliferation of MG-63 cell line in the time-dose dependent manner.When the concentration reached 4 mmol/L,this inhibitory effect was the maximum.When IP6 concentration was 0.5 mmol/L or 1 mmol/L,the proliferation of osteoblasts was not obviously inhibited.When it was 2 mmol/L,the proliferation was slightly inhibited.A concentration of 4 mmol/L caused the apoptosis of osteoblasts.Conclusion IP6 can inhibit the proliferation of osteosarcoma cell line MG-63 and lead to its apoptosis.The optimal concentration is 2 mmol/L for achieving anti-cancer effects.
