Incisional hernia is open a major postoperative complication that abdominal surgery remains. The incision type, suture technique, and the choice of primary suture materials are the main factors affecting wound healing. Prophylactic subfascial non-absorbable mesh can be used in high-risk patients to prevent in-cisional hernia.

Intermedin can promote tumor angiogenesis through a variety of signaling pathways. Hypoxia of tumor cells can induce an increased expression of intermedin. Recently, there have been a surge of researches on the relation between intermedin and tumor initiation, progression and metastasis. Intermedin may be a new target for tumor therapy.

Objective To explore the correlation between anemia and the pathogenesis and prognosis of patients with lung cancer. Methods From January 2013 to December 2014, 257 patients with primary lung cancer who were firstly treated at the First Affiliated Hospital of Anhui Medical University were retrospectively analyzed. The clinical data of the patients were collected and the patients were divided into anemia group and control group. The relationship of gender, age, and pathogenesis with anemia was analyzed by x 2 test. Survival analysis was evaluated by Kaplan-Meier and Log-rank test. Results The TNM stage, lymph nodes and remote metastasis , and ECOG score between the two groups were statistically different (x 2 values were 7.94, 4.97, 4.69, 9.02, all P< 0.05). The survival of the two groups showed statistical differences (x2=7.02, P=0.008). Conclusion Anemia might be correlated with the stage, lymph nodes and remote metastasis, ECOG score and prognosis of patients with lung cancer.

Acquired resistance of EGFR-TKIs has become the major limitation of the efficacy of targeted therapy for lung cancer. Lung cancer has been treated by traditional Chinese medicine (TCM) combined with EGFR-TKIs, which originated from clinic. In recent years, reversing research has been conducted based on clinic application to discuss TCM intervening, improving and reversing EGFR-TKIs acquired resistance becoming a novel target for research. This article reviewed mechanism and effects of TCM herbs and compounds’ with the efficacy of clearing away heat and toxic materials, promoting blood circulation to remove blood stasis strengthening the body resistance, and invigorating the circulation of blood, and proposed that the whole regulation and targeted therapy of TCM may carry out synergistic effect and become innovation treatment model for lung cancer.

Endothelin-1 (ET-1) was characterized as a powerful vasoconstrictor and mitogen for smooth muscle. ET-1 binds to two types of receptors: ET_ A-R and ET_ B-R. Pulmonary arterial hypertension (PH) is a severe condition characterized by a progressive increase in pulmonary vascular resistance. The Endothelial dysfunction plays an important role in the development of pulmonary arterial hypertension. PH can be treated by antagonism of ET-1.

Pancreatic cancer was one of common malignant tumors of the digestive tract, early diagnosis of which was difficult and surgical resection rate was low. The prognosis was poor, and its incidence increased year by year. Conventional treatment of pancreatic cancer includes surgery, radiotherapy and chemotherapy, but 90％ of the patients had lost the surgical opportunity when they see a doctor, and not sensitive to radiotherapy and chemotherapy. Relative to these traditional treatments, gene therapy is an innovative approach for the treatment of pancreatic cancer and had attracted wide attention in recent years. Many gene therapy drugs for pancreatic cancer had now entered Ⅰ / Ⅱ clinical trials. The gene therapy techniques for pancreatic cancer included antisense gene therapy, suicide gene therapy, immune gene therapy, and oncolytic virus therapy. In this article, we reviewed recent advances in gene therapy for pancreatic cancer.

Expansive type of hepatocellular carcinoma (HCC) is a subtype of HCC. Correlation between the preoperative sonography and postoperative pathology was studied in 35 cases of HCC. According to the classification of nakashima, 21 cases belonged to the expansive type whereas the other 14 cases the infiltrative type. Different from the infiltrative type. the expansive type of HCC had four specific sonographic appearances: hypoechoic ring, hypoechcic halo, pedunculated and small nodular echo which had different pathological bases. Expansive tyje of HCC was not so commonly seen as infiltative type but its rate of surgical resection was mu~h higher than that of infiltratine type (JP< 0. 01). Thus, it is the kind of HCC with significant clinical importance. Preoperative ultrasonographic diagnosis help to decide the way of treatment.

Exosome is a sort of vesicle structure attached to cell membrane and released by cells, which contains numerous bioactive molecules, such as proteins, lipids, mRNA, microRNA and DNA fragments. These bioactive molecules are involved in the regulation of many biological processes, not only the participation in the occurrence and development of diverse diseases, but also the close relationship with the invasion and metastasis of tumors. The recent study has indicated that lots of exosomes released from cancer cells participate in a variety of pathological processes as a messenger of cell functions. This article will elaborate the function and application of exosomes in some malignant cancers.

BACKGROUND:Bionic structure is one of the most important goals of scaffold design in tissue engineering. However, the majority of the bionic scaffolds do not have the capacity of sustained release of growth factors.
OBJECTIVE:To fabricate a novel biomimetic nanofibrous heparin/gelatin scaffold and investigate the characterization of the scaffolds including the microstructure, the mechanical strength andin vitro recombinant human bone morphogenetic protein-2 (rhBMP-2) release.
METHODS:Heparin-conjugated gelatin was prepared by chemical crosslinking and mixed with gelatin at different ratios. Nanofibrous composite scaffolds with different ratios of heparin-conjugated gelatin (0, 20% and 40%) were fabricated by using a thermaly induced phase separation combined with particle leaching technique. The amount of conjugated heparin in the scaffolds, scaffold microstructures and mechanical strength were detected and observed. The release kinetics of rhBMP-2 from the scaffolds with different concentrations of heparin conjugated gelatin was detected using ELISA method.
RESULTS AND CONCLUSION:The composite scaffolds possessed abundant porosities, good mechanical properties, and biomimetic nano-structures. The macroporous size was 250-420 μm. When the ratio of heparin-conjugated gelatin was 0, 20% and 40%, the content of heparin in the scaffolds was 0, (12.82±2.49) and (25.08±3.69) mg/g, respectively, with significant differences; the elastic modulus of the composite scaffolds was (299±38), (286±40) and (236±33) kPa, respectively, with insignificant differences (P > 0.05). With the increase in the content of heparin-conjugated gelatin, the rhBMP-2 adsorption capacity of the nanofibrous heparin/gelatin scaffold is improved, thereby significantly reducing the burst release of rhBMP-2 and prolonging the releasing time.

Objective] Inquire Sun Simiao’s arthralgia syndrome related theory and drug laws in Essential Recipes for Emergent Use, with a view to a more comprehensive understanding of arthralgia to broaden the train of thought, improve the clinical efficacy. [Methods] Read Essential Recipes for Emergent Use book, combined with knowledge of Chinese medicine, to study involved arthralgia syndrome theory and relevant prescriptions and drugs for statistical summary. [Results] Sun Simiao believed arthromyodynia causes included three cold wet gas, kidney, heat etc. The use of medicine in treatment of arthralgia syndrome of wind;pay attention to helping Yang deficiency. Arthromyodynia for different symptoms and disease drug use had their own unique experience. [Conclusion] Sun Simiao’s Essential Recipes for Emergent Use content is rich, extensive and profound, its treatment of Bi syndrome has quite academic value, today, the therapeutic theory for treatment of clinical syndrome has still an important guiding significance.
