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.

Liver fibrosis is the excessive accumulation of extracellular matrix (ECM) proteins that occurs in most types of chronic liver diseases. Hepatic stellate cells (HSCs) are major sources of the excess ECM deposited in fibrotic liver. Transforming growth factor ? (TGF-?) is considered to play a generic role in the development of tissue fibrosis, as it stimulates the synthesis and deposition of ECM components. Smad pathways are central mediators of signals from the receptors for transfor- ming TGF-? to the nucleus. However, growing biochemical and developmental evidence supports the notion that non-Smad pathways also participate in TGF-? signalling. TGF-? signalling pathways play an important role in regulating tissue homeostasis and have been implicated implicated in diverse pathological conditions. It is oow our challenge to design ways of blocking the fibrosis-specific actions of TGF-? through downstream signalling pathways and mediators without compromising the other activities of this multifunctional cytokine, which is essential for health.

Objective Mapping the sites of earliest activation in AF patients with rheumatic heart disease. Finding out the ratio of AF originate from the pulmonary veins. Methods There were 9 patients with valvular atrial fibrillation (1 male, 8 females age (42?13) years, histories of rheumatic heart disease (11?9) years, and mitral valve area 1.01?0.02 cm2) involved in the research. 3 patients had organized thrombus in left atrial appendage. 6 patients with persistent AF received anticoagulation therapy (warfarin 2 or 3 weeks) and drug cardioversion (amiodarone 400 mg, three times per day, for 7 days) before procedures, while other 3 patients with paroxysmal AF received neither anticoagulation therapy nor drug cardioversion. All patients received percutaneous balloon mitral valvotomy (PBMV). After finished PBMV, four multipolar electrode catheters were placed in the high right atrium (HRA), coronary sinus (CS), left atrium (LA) and pulmonary veins (PVs). S1S2 and S1S2S3 programmed stimuli were delivered in HRA, CS, LA and PVs respectively. For the patients who failed to induce AF, burst stimuli were used. Results 11 AF generating sites, which induced by S1S2 and S1S2S3 programmed stimuli, could be confirmed by identification of the earliest regions of atrial activation for the first AF cycle. However, 1 AF obtained by 260 ms RR interval burst stimuli, affirmed by shortest activation cycle length. All confirmed 12 AF original sites were original as following: RA (n=4), LA (n=1), CS (n=2); PVs (n=5). Among the 5 PVs original sites, 3 was from left superior pulmonary vein, while the other 2 were from right superior pulmonary vein and left inferior pulmonary respectively. Conclusion PVs could be the ectopic origin of valvular AF.
