Methods During the period from October 2011 to October 2013 at authors’ hospital, a total of 34 patients received basilar artery angioplasty. According to the hospital nursing core regulations , hanging of nursing warning tags, monitoring of blood pressure of both upper limbs, measurement of average blood pressure of both upper limbs after admission, and 72 hours ECG monitoring of blood pressure after operation as well as maintaining the patient’s blood pressure at a stable level around 110 - 120/70 - 80 mmHg, etc. were strictly carried out. Results Before operation no falling on the ground occurred in all the patients. After the operation, no severe complications such as hemorrhage occurred. All patients were in satisfactory condition at the time of discharge. Conclusion Strictly carrying out nursing core regulations, rigorously performing the nursing measures and monitoring the blood pressure before, after and during basilar artery angioplasty are helpful in reducing the incidence of perioperative complications.

Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

AIM: To study the role of NOS2 in the devel op ment of cardiac dysfunction after rat myocardial infarction by observing effects of S-methylisothiourea (SMT) on left ventricular morphology and haemodynamics. METHODS: An selective NOS2 inhibitor, was used. Administration o f SMT by gavage began 30 min before coronary ligation. Six weeks later, left ventricular morphologic and haemodynamic parameters were o bserved,and NOS2 expression, plasma NO 2-/NO 3- level and myocardial fibr osis were studied.

Abstract BACKGROUND: As an emerging technology, tissue-engineered skin has great application prospects. Keratinocyte growth factor (KGF) is proved to promote the proliferation of epidermal cels. OBJECTIVE: To evaluate the effect and characteristics of tissue-engineered skin carrying KGF nanocapsules in repairing skin defects of nude mice. METHODS:(1) The acelular dermal matrix loading KGF (KGF-ADM) was constructed. The human epidermal stem cel population and fibroblasts were captured and cultivated, and then identified. Epidermal stem cels were cultivated on the KGF-ADM and their growth was observed. The tissue-engineered skin loading KGF nanocapsules was transplanted onto the ful-skin defects on the back of nude mice compared with a blank group without keratinocyte growth factor nanocapsules and a control group with skin autograft. In 2, 4 and 6 weeks after transplantation, the contraction and histological healing of the skin were observed respectively. Then anti-human keratin 10-FITC and β1-integrin-Cy3 immunofluorescence were applied to detect the origin, growth and differentiation of stem cels in the epidermis and dermis. RESULTS AND CONCLUSION: The epidermal stem cel population grew wel on the surface of KGF-ADM and attached tightly. There were smal round epidermal stem cels and polygonal terminaly-differentiated cels, which presented with partly cloning growth and a tendency of merging into pieces. The results of tissue-engineered skin with KGF nanocapsules in repairing the skin defects were better than those of the blank group and the control group in 2, 4 and 6 weeks after transplantation. The transplanted skin could fuse with adjacent skin completely, but stil showed some contraction. Under the microscope, they showed good epidermis with layers and normal keratose stratum, and meanwhile, there were stil some β1-integrin+ cels at 8 and 10 weeks, which were epidermal stem cels or transient amplifying cels identified by immunofluorescence. These findings indicate that the tissue-engineered skin carrying KGF nanocapsules has good outcomes in repairing skin defects of nude mice, which is better than common tissue-engineered skin without KGF nanocapsules and autogeneous skin transplantation.

Toll-like receptor 4 (TLR4) plays an important role in inflammation and immune response.MicroRNAs (miRNAs) are involved in the regulation of TLR4 signaling pathway in multiple levels and various molecules,which play an important role in inflammatory reaction.A variety of miRNAs are involved in the regulation of TLR4 signaling pathway,and the TLR4 signaling pathway can induce a variety of miRNAs.Chronic diseases such as diabetes,Alzheimer's disease and cardiovascular disease are closely related to inflammatory response.The regulatory role of TLR4 signaling related miRNAs has attracted much attention in inflammatory diseases.In this review,the research progress of TLR4 signaling pathway related miRNAs in the regulation of inflammatory response is summarized,which provides a new research direction for the clinical diagnosis and treatment of inflammatory response related diseases.

Objective To investigate the effects of Thomas solution in combination with nitroglycerine of different concentrations on rat cardiac preservation for 8 h. Methods Thirty Wistar rats were selected,and Langendorff heart perfusion models were established.Rats were randomly divided into Thomas solution group,Thomas solution+4?10-6 mol/L nitroglycerine group and Thomas solution+4?10-5 mol/L nitroglycerine group(n=10).After hypothermic preservation(4 ℃)for 8 h,the cardiac function of each group was determined.Tissues of left ventricular wall were obtained,and changes of myocardial ultrastructure were observed by electron microscopy. Results Compared with Thomas solution group,the cardiac function was significantly improved and the myocardial ultrastructure injury was less severe in Thomas solution+4?10-5 mol/L nitroglycerine group after hypothermic preservation(4 ℃)for 8 h,while there was no significant difference in myocardial ultrastructure injury and cardiac function between Thomas solution group and Thomas solution+4?10-6 mol/L nitroglycerine group. Conclusion Thomas solution in combination with 4?10-5 mol/L nitroglycerine can significantly improve the preservation effects for isolated hearts in rats.
