Objective To investigate the apoptosis response to mechanical stretch in human alveolar type Ⅱ epithelial cells A549.Methods First,A549 cells were given different stretch(0%,5%,15%,30%) at frequency of 0.5 Hz for 4 h.Then,A549 cells were stretched for different periods(0 h,2 h,4 h,8 h) at stretch 15%,0.5 Hz.Last,A549 cells were stretched for different frequency(0 Hz,0.2 Hz,0.5 Hz and 1 Hz) at stretch 15% for 4 h.The early apoptosis was detected by flow cytometry. Results A549 cells submitted to cyclic stretch caused the early apoptosis in a time-,stretch-and frequency-dependent manner.In details,at 0.5 Hz and 4 h stretch-dependence occurred,at 15% stretch and 0.5 Hz time-dependence occurred,and at 15% stretch and 4 h frequency-dependence occurred. Conclusion Mechanical stretch can induce the early apoptosis in human alveolar type Ⅱ epithelial cells A549,which may be one of the mechanisms of ventilator-induced lung injury.

Objective To investigate the characteristics of nerve injury and incidence of carpal tunnel syndrome(CTS)indiabeticpatientsbymeasuringthenerveconductionvelocity(NCV). Methods Atotalof387 inpatients with type 2 diabetes were selected in Kaifeng Central Hospital from July 1, 2011 to October 1, 2014. The abnormal rates of NCV between left and right or male and female for the same name nerve were compared. The examinations to median nerves were paid particular attention and the segmental test was performed. Results Among 387 patients, 333 cases showed abnormal NCV, and 162 patients (41. 9%) presented with CTS. The incidence of sensory nerve injury was higher than that of motor nerve injury. The nerve injury often occurred in the dominant hand, but the injury of bilateral hand were also found in some patients. In 162 patients with CTS, 91 patients presented with clinical manifestations and signs, and the rest were without discomfort in their hands. The percentages of SCV(34. 1%vs 25. 6%, P=0. 012) and MCV (40. 3% vs 29. 5%, P=0. 020) abnormality in the right median nerve were higher than those in the left side. No significant difference of the other nerves was found between left and right. Significant differences in the percentages of abnormality in SCV of the left median nerve (21. 4%vs 30. 5%, P=0. 047) and the right median nerve (28. 6%vs 40. 1%, P=0. 013) between man and woman were found. The abnormal rates of other nerves were without statistically significant between man and women. Conclusions The incidence of CTS is high in diabetic patients. Usually, it firstly occurs in sensory nerves, followed by motor nerves, especially in the dominant hand.

Objective To explore the expression change of Toll Like Receptor 4 (TLR4) in lung ischemia-reperfusion injury in rabbits and the influence of clemastine fumarate on it. Methods Fifty rabbits were divided into five groups randomly (n=10): Sham (N+S), reperfusion for 2 hours (N+I1/R2), reperfusion for 4 hours (N+I1/R4), clemastine fumarate + reperfusion for 2 hours (F+I1/R2) and clemastine fumarate+reperfusion for 4 hours (F+I1/R4). The ischemia time in each group was 1 hour and normal saline was given respectively in groups of N+S , N+I1/R2 and N+I1/R4. Western blotting , RT-PCR and immunofluorescence were used to detect the expression of TLR4 in lung tissue , and the changes of ultrastructure in ischemia-reperfusion lung tissue were observed by electron microscope. Result The expression of TLR4 was elevated obviously in ischemia-reperfusion lung tissue (P<0.05), and there was positive correlation between the increased TLR4 level and reperfusion time (P<0.05), the swelled and thick-ridge mitochondria were observed in type II alveolar epithelial cells after LIRI (P<0.05); but clemastine fumarate inhibited the expression of TLR4 in lung tissue significantly caused by LIRI (P<0.05). And the mitochondria injury was reduced in the groups of clemastine fumarate. Conclusion TLR4 expression is elevated in lung tissue after LIRI; clemastine fumarate inhibits the expression of TLR4 caused by LIRI and protects the lung tissue from LIRI in rabbits.

Objective To investigate the relationship between cognitive function and emotional status in functional constipation patients.Methods Thirty-five functional constipation patients (the functional constipation group) and 24 healthy controls (the HCs) were enrolled in an event-related potential (ERP),behavior and electroeneephalogram study while performing an oddball auditory task.Response time,accuracy,latency and P300 amplitude were compared between the two groups.The Hamilton depression rating scale (HAMD-17),Hamilton anxiety scale (HAMA),symptom check list-90 (SCL-90) and Eysenck personality questionnaire (EPQ) were administered prior to the oddball task.Results The average HAMD-17,HAM A and SCL-90 (the somatization,obsessive-compulsive disorder,depression,anxiety and psychosis dimensions) scores of the functional constipation group differed significantly from those of the HCs.The intro-extraversion and neurosis dimensions of the EPQ were also significantly different.There was no significant difference in response time or latency between the two groups.The ERP results showed that the P300 amplitudes at the F3 and F7 sites were significantly different between the functional constipation group and the HCs.But there was no significant difference in P300 latencies at F3 or F7 between the two groups.Conclusions The findings suggest that patients with functional constipation are more susceptible to depression and anxiety,as well as somatization,obsessive-compulsive tendencies and other neurotic personality characteristics.Patients may employ psychological defense mechanisms to avoid the depression and anxiety.The ERP results imply there may be the implicit cognitive dysfunction with emotion in patients with functional constipation.

Osteoclast, a huge coenocytes,originates from mononuclear macrophages or monocytic series hematopoietic precursor cell, plays an important role in the progree of bone resorption. Formation and abnormal activity of osteoclast may cause osteoprosis, rheumatoid arthritis and aseptic loosening after arthroplasty. Therefore, osteoclast is the target for treating these disease. At present, a lot of study on formation of osteoclast were reported, but the study on how to identify and degradation of bone tissue is not yet reported. Bone mineral are seen as important component of identifing osteoclast, and the research suggested that bone matrix is not the essential ingredients of activiting osteoclast, petri dish covered by vitronectin also can make osteoclast occure certain form of bone resorption, vitronectin plays an significant role in activiting osteoclast. Otherwise, the research found that swallowing and secretion of bone matrix degradation products is benefit for differentiation of osteoclast and maintain of function, and this may be therapeutic target for treatment of musculoskeletal disorders.

MicroRNA(miRNA) is a class of non-coding RNA that plays an important role in gene expression and controlling. In recent years,the role of miRNA in the development of the disease has aroused great interest. Abnormal osteoclastogenesis and persistent inflammatory response induced by wear particles or osteoblast differentiation and maturation is the main cause of aseptic loosening in joint replacements. New researches shows that persistent inflammatory response, osteoclastogenesis and osteoblast differentiation are closely associated with miRNA, suggesting that there are certain relations between miRNA and aseptic loosening of prostheses. Additionally, the alteration of the expression levels of some miRNA may be curative for aseptic loosening. With the findings of the new miRNA targets, the important role of miRNA is further confirmed.
