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.

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.

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.

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.

Objective To investigate the expression of intermedin (IMD) in plasma and tissues of lung cancer patients compared with control group and to explore the relationship of IMD with the stage and pathological type of lung cancer. Methods The content of IMD in plasma of 88 lung cancer patients measured using ELISA, 36 lung cancer tissue using immunohistochemistry, compared with control groups. Results Healthy control group IMD level [(38.68±12.65) pg/ml] was lower than lung cancer group [(81.61 ± 30.78) pg/ml] (t =-5.818, P <0.05); There was no significant difference of IMD between small cell [(68.61 ± 30.01) pg/ml] and non-small cell lung cancer [(75.51 ±32.74) pg/ml] (t =-0.680, P >0.05); IMD in stage Ⅳ is higher than stage Ⅰ - Ⅲ (t =-3.444, -3.093, -3.955, P <0.05); IMD with distant metastasis is significantly higher than that without distant metastasis (t =8.052, P =0.000). IMD expression in lung cancer tissues [23/36 (63.9 %)] is significantly higher than adjacent tumor tissues [5/21 (23.8 %)] (x2= 8.525, P <0.05). IMD in Stage Ⅲ[14/17(82.4 %)] is significantly higher than in stage Ⅰ [1/5 (20.0 %)] (x2 = 6.924, P =0.009). Conclusion The expression of IMD in lung cancer patients is significantly higher than control groups. Expression has correlation with stage and metastasis, which might play a vital role in the pathogenesis of lung cancer.

Hypertension in elderly patients is a common and frequent disease which could cause stroke, heart failure and renal dysfunction. The pathogenesis of hypertension in the elderly is different from that in the young and middle-aged people, and its clinical characteristics including frequent isolated systolic hypertension, variable blood pressure, high pulse pressure, multiple complications, serious target organ damage, and so on. High prevalence, disability and mortality rates and low awareness, treatment and control rates are prominent phenomena in the elderly patients with hypertension, bringing many difficulties for clinical treatment. Presently, drug therapies for elderly patients mainly include Western medicine (WM), traditional Chinese medicine (TCM), and integrated traditional Chinese and Western medicine. WM therapy has superiority in lowering blood pressure intensively with clear mechanism, but has more adverse reactions. The effects of TCM therapy are multilinked, and TCM is good at reducing side effects and improving symptoms, but TCM preparation falls behind and its hypotensive effects are weak and slow. Furthermore, more multicenter, randomized, controlled and double-blinded clinical trials with large sample are needed to identify the effects of TCM therapy. Based on combination of TCM syndrome differentiation and WM disease differentiation, treatment programs of integrated traditional Chinese and Western medicine would take advantages of both TCM and WM treatment modalities, and are worthy of being studied in the future.

Free radicals are highly reactive molecules generated predominantly during cellular respiration and normal metabolism. Imbalance between cellular production of free radicals and the ability of cells to defend against them is referred to oxidative stress (OS). OS has been implicated as a potential contributor to the pathogenesis of ischemic cerebrovascular diseases. After brain injury by ischemia, the production of reactive oxygen species (ROS) may increase, leading to tissues damage via several different cellular molecular pathways. Radicals can cause damage to cardinal cellular components such as lipids, proteins, and neucleic acids, leading to subsequent cell death by modes of necrosis or apoptosis. Treatment with antioxidants may prevent propagation of tissues damage and improve both the survival and neurological outcome. The present paper reviews the antioxidants therapy in ischemic cerebrovascular disease, discusses probable reasons of inconsistency between animal experiments and clinical trials on antioxidants, and puts forward strategies against oxidative stress in the treatment of ischemic cerebrovascular diseases.

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.
