Orthodontic tooth movement (OTM) is a very complicate mechano-biological procedure which is accomplished by the remodeling of periodontal tissues via orthodontic force.As the connective tissue between alveolar bone and cementum,periodontal ligament plays a vital role in the response and conduction of orthodontic force.The susceptible response of periodontal ligament to orthodontic force during OTM is a critical factor on inducing and modulating periodontal tissue restitution.This article reviews the concrete role of periodontal ligament and its mechano-biological behavior during OTM,discusses its mechanical response and biological mechanism respectively on histological,cellular and moleucular levels.

Objective To investigate the clinical effect of adopting B-type ultrasound guided peripherally inserted central catheter (PICC) in the patients with lung cancer.Methods Two hundreds and ninety-five cases of lung cancer undergoing PICC in our hospital from January 2011 to May 2016 were selected as the research subjects and divided into the observation group (151 cases) and control group (144 cases) according to the PICC methods.PICC in the observation group adopted the B-type guided modified Seldinger technique,while the control group adopted the conventional method.The venous thrombus occurrence situation in the two groups was comparatively analyzed.Results (1) The platelet count (PLT),plasma D dimer (D-D) and thromboxane B2 (TXB2),endothelin (ET),6-keto-prostaglandin F1 alpha (6-keto-PGF1α) before PICC had no signigicant difference between the two groups (P>0.05).PLT,D-D,TXB2 and ET at 12,24 h after PICC in the observation group and control group were gradually increased,while plasma 6-keto-PGF1α was gradually decreased,the intra-group difference among different time points had statistical significant (P<0.05).PLT and plasma D-D,TXB2 and ET in the observation group were significantly lower than those in the control group,while keto-PGF1α was significantly higher than that in the control group,the difference between the two groups was statistically significant(P<0.05).(2)The incidence rate of venous thrombosis in the observation group was significantly lower than that in the control group,the difference was statistically significant between the two groups (P<0.05).Conclusion Adopting B-type ultrasound guided modified Seldinger technique for PICC in the patients with lung cancer has much lower incidence rate of venous thrombosis.

Objective To explore the influence of psychological nursing intervention on reducing the incidence of depression, and on the quality of life of patients with depression after stroke. Methods Firstly, we randomly divided the patients with depression after stroke into two groups, the study group with 90 patients, and the control group with 90 patients. And then we evaluated the best way of clinical care for the disease by observing the incidence of depression and the quality of life of the two groups before and after treatment.Results The incidence of depression in patients in the two groups decreased after nursing intervention. The decreasing degree of the study group was more significant than the control group, and the differences had statistical significance ( <0.05) . Life quality of patients of the two groups were improved. The study group had more significant effect than the control group, the differences had statistical significance ( < 0.05) .Conclusion Enhancing the psychological nursing intervention is valuable in clinical application to improve the mood state of patients with cerebral stroke, reduce the incidence of depression after stroke, promote rehabilitation exercise, and improve life quality.

The potential cardioprotection can be involved during ischemic preconditioning in heart which mechanisms remain unknown yet. It is reported that sarcolemmal and mitochondrial K_(ATP) channels mediate cardioprotection, and they play distinct myoprotective roles during ischemic preconditioning. This paper reviews the present progress in myocardial sarcolemmal and mitochondrial K_(ATP) channels in ischemic preconditioning. [

MicroRNA (miRNA) is a kind of small molecular non-coding RNA, which plays important roles in biological processes such as cell differentiation, proliferation, invasion and apoptosis by regulating the expression of target mRNA. Some miRNAs have the functions of oncogene or tumor suppressors in tumor genesis and development. In recent years, the study of miRNA on the early diagnosis, clinical staging, personalized treatment and prognostic evaluation in esophageal cancer is on the rise. Discoveries of miRNAs with close relations to esophageal cancer will be reviewed.

To explore how to combine the culture of traditional Chinese medicine and modern hospital culture better, so as to enhance the core competitiveness of the hospital.AsChinese cultural spirit can be summed up by “be-nevolence”, “harmoniousness”, “sincerity”, we can put the “benevolence” into the hospital spirit culture, make“harmoniousness” reflect the service culture, and create the brand culture with “sincerity”.

[Objective] To discuss the clinical effect of SAP treated with Qingyi Decoction combined with mirabilite. [Method] Select 103 such cases, ran-domly divide them into treatment group 56 cases and control group 47 cases;both were given basic treatment of fasting, gastrointestinal decompression and anti-infection; the treatment group was added with Qingyi Decoction by nasal feeding and enema, and outer application of mirabilite. After treatment, compare their sitiuations of abdominal pain and distension, vomiting and nausea, recovery and relieve of life signs, in-hospital time and complications. [Result] The effecitve rate was 98.21% for treatment group, and 80.85% for control one, the difference between them had statistical meaning; the observa-tion indexes were better in treatment group than other one, with difference of statistical meaning. [Conclusion] Qingyi Decoction combined with mirabilite treating SAP can promote early recovery of gastro-intestinal function, effectively reduce infection, abdominal abscess, false cyst and other compli-cations, as wel as improve the prognosis.
