Objective To discuss the clinical value of transesophageal echocardiography used in extracorporeal circulationcardiac valve replacement. Methods 89 patients received extracorporeal circulation cardiac valve replacement in our hospital from January 2012 to December 2014 were included in the study. Transesophageal echocardiography were performed preoperatively, intraoperation and postoperatively and the findings were compared to the result of preoperation transthoracic echocardiography exam. The measurement of aortic annulus diameter and detection rates of calcification obtained by transthoracic and transesophaged echocardiography were compared. Changes in heart function parameters before and after operation were compared. The alternations in surgery plan made after pre-operative transesophageal echocardiography exam and any relevant treatment or procedure performed according to intra-operation transesophageal echo findings were recorded. All the patients were followed up for 6 months - 40 months. Results Before extracorporeal circulation cardiac valve replacement, the aortic annulus diameter measured and detection rates of calcification by transthoracic echocardiography were smaller and lower than actual surgical pathology results ( P < 0. 05 ) . No differences in the results from transesophageal echocardiography of two-dimensional and three-dimensional examination when compared to pathological findings ( P > 0. 05 ) . Conclusions For patients receiving extracorporeal circulation cardiac valve replacement, transesophagus echocardiography examination is helpful to guide the selection of valve stent and operation methods.

Objective To detect the serum levels of IL-6 and CRP in patients with acute type A aortic dissection complicated with pulmonary injury and inflammatory response. Methods From January 2007 Month to February 2016,216 patients with acute type A aortic dissection were admitted to our hospital. Among them,there were 120 male and 96 female patients,with a mean age of 52.1 years. All patients underwent cardiac ultrasound and other imaging studies. They were diagnosed and hospitalized immediately after the onset. Treatment lasted for more than 1 week. In a calm state of oxygen ,oxygenation index ≤200 preoperative lung injury is defined as positive. In this study ,according to the definition of the lung injury ,patients were divided into positive and negative lung injury groups. There were 72 positive and 144 negative cases among 216 patients. All patients were hospitalized. Every 4 hours,arterial oxygenation index is calculated. At the same time blood samples were tested for C-reactive protein(CRP)and interleukin-6(IL-6)levels. Data was analyzes by SPSS20.0 statistical software and counted byχ2 test. The results were plotted as the percentage,the measurement data with the t test,with(x ± s) to represent,evaluate serum levels of CRP and IL-6 levels with acute type A aortic dissection complicated by the relationship between lung injury. Results The differences of patients from two lung injury groups in gender,age, smoking,alcohol consumption,and other aspects of common chronic diseases were not significant(P>0.05);the difference between the pre-operative examination of several experimental studies in echocardiography were also no statistically significant(P > 0.05);two groups of patients,serum CRP positive group lung injury peak level and peak IL-6 levels were significantly higher in patients with acute lung injury negative group (P > 0.05). Further study of lung serum CRP in patients with damage to the relationship between IL-6 levels and oxygenation index found after dissection. Patient's oxygenation index decreased ,and serum C-reactive protein and interleukin-6 levels were rising rapidly ,reaching peak levels ,and then ,with the patients with inflammatory response decreased oxygenation index showed an upward trend. Conclusion Inflammatory reaction in acute type A aortic dissection plays a key role in the lung injury. In result ,patients'sicken time is prolonged ,which was closely related to serum C reactive protein(CRP),interleukin 6 levels and hypoxemia. Active anti-inflammation treatment before surgery may improve the patient's oxygenation status.

BACKGROUND: External preparations treatment of fractures in traditional Chinese medidne are mostly ordinary hard-paste, cream, ointment, which lack of modernized traditional Chinese medicine transdermal delivery systems, and the treatment has poor drug absorption and simple process. The treating procedure needs to be used repeatedly, which would affect fracture external fixation and lead to unsatisfactory therapeutic effect. In this Paler, the extemal treatment of traditional Chinese medidna was combined with advanced micro-nano-technology to develop a new medical complex functional materials-micron traditional Chinese medicine functional lining material, which is an organic combination of diaplasis, fixation and local drug remedy, which provides a better treatment for fractures. OBJECTIVE: To explore the effect of micron tradifional Chinese medicine functional lining material on the healing of fracture in rabbits, METHODS: After model preparation, rabbits were randomly divided into 4 groups: rabbits in the micron group were treated with micron traditional Chinese medicine functional lining material plus plaster external fixation; those in the traditional Chinese medidna control group were treated with ordinary Chinese medicine functional material plus plaster extemal fixation; those in the lining material control group were treated with ordinary lining material added plaster extemal fixation; those in the natural healing control group had no special treatments. The effect of fracture healing was evaluated by X-ray at 2, 4 and 6 weeks after modeling. The serum concentration of alkaline phosphatase, calcium and phosphorus was detected respectivaly before modeling and at 2, 4 and 6 weeks after modeling. RESULTS AND CONCLISION: ①X-rap examination:After 6 weeks the external was almost copletly absorbed and medullary cavity was completely recanalizad in the micron group, while fracture line disappeared and the external callus began to be absorbed and medullary cavity was not recanalized in the traditional Chinese medidne control group. Additionally, there were case of non-union stump hardening in natural healing group. ②Serum biochemistry:The activity of alkaline phosphatase reached a peak after 2 weeks in micron group, which was 2 weeks ahead of time compared with that in traditional Chinese medicine control group. And the peak concentration of alkaline phosphatase in micron group was higher than other groups. After 4 weeks serum calcium concentration started to fall significantly and phosphorus concentration started to rise significantly in micron group, as was statistically significant compared with other groups. After 6 weeks serum calcium concentration in micron group had fallen to normal level, while that in other groups was higher than normal. And phosphorus concentration in micron group increased significantly, which was statistically significant compared with natural healing group. The results demonstrated that micron feature traditional Chinese medicine lining matedat can enhance the activity of alkaline phosphatase, decrease the serum concentration of calcium and increase the serum concentration of phosphorus and the product of calcium and phosphorus, therefore, promote the healing of fracture, It shows that micron traditional Chinese medicine functional lining matedal plays a stronger effect on promoting the healing of fracture than that of ordinary Chinese medicine functional lining material.

Objective To compare three different internal fixations using dual plates in treatment of type C distal humerus fractures.Methods A total of 59 patients with type C distal humerus fractures fixed with dual plates between January 2004 and December 2008 were enrolled in the study,including 34 patients managed by perpendicular dual plate internal fixation (Group A),14 patients by dorsal dual plate internal fixation (Group B),and 11 patients by parallel dual plate internal fixation (Group C).Functional outcomes of injured elbow joints were assessed using Mayo elbow performance score (MEPS).Fisher' s exact probability,chi-square test and variance analysis were used to compare the perioperative variables among groups.Results The patients were followed up for average 28 months (range,12-55 months),which showed that all fractures were smoothly healed with satisfactory curative effects in each group.There were no significant differences with respect to functional outcomes among three groups.The patients with surgery difficulty in Group C were more than those in other two groups.Besides,an additional intercondylar screw was always required in Groups A and B,but rarely in Group C.Conclusions All internal fixations with three dual plates are effective in management of type C distal humeral fractures.The location of plates is determined by experiences of orthopedic surgeons and specific fracture type.

To control the quality of Humulus scandens, the quality standard was established in this study. According to the method recorded in the Appendix of Chinese Pharmacopoeia (2010 Edition) , the water and ash inspections were carried out. The component luteoloside and cosmosiin in Humulus scandens were identified and assayed by TLC and HPLC. The results showed a strong characteristics microscopic of Humulus scandens, and trichoromethane-methanol-formic acid (10: 3: 0. 3) as the mobile phase of TLC, the spots at 365 nm with a UV lamp was clear. The 16 batches of samples were analyzed by HPLC with a gradient elution of acetonitrile and phosphate solution (0.2%) at a flow rate of 1.0 mL · min(-1) and detected at 350 nm. The content of luteoloside was 0.015%- 0.651% (average 0.148%); the content of cosmosiin was 0.003%-0.118% (average 0.036%).

Objective: To observe the clinical efficacy and eligibility of thumb-tack needle therapy based on meridian differentiation in treating cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. Patients in the control group received thumb-tack needle based on conventional point selection, while those in the observation group received thumb-tack needle according to meridian differentiation. The visual analog scale (VAS) and clinical symptom scores in the two groups were compared before and after treatment, and the clinical efficacy of the two treatments was observed. Results: After treatment, the VAS score in both groups dropped significantly (both P<0.01), and the VAS score in the observation group was lower than that in the control group (P<0.01). The clinical symptoms score in both groups dropped significantly (all P<0.01), and the clinical symptoms score in the observation group was lower than that in the control group (P<0.01). The total effective rate in the observation group was higher than that in the control group (P<0.05). Conclusion: Thumb-tack needle therapy based on meridian differentiation can reduce pain score, improve clinical symptoms in patients with cervical radiculopathy, and produce more significant efficacy compared with conventional thumb-tack needle therapy.

OBJECTIVETo investigate the relationship between UNC5b gene expression and angiogenesis of hepatocellular carcinoma (HCC).

METHODSIn situ hybridization was performed to detect the expression of UNC5b mRNA in HCC samples, paracarcinomatous liver tissues samples and normal liver samples. The relationship between UNC5b mRNA expression and the HCC clinicopathological features were also analyzed. Human umbilical artery endothelial cells were isolated and stimulated with HCC tissues homogenate, vascular endothelial growth factor and basic fibroblast growth factor. Then RT-PCR was employed to detect the expression of UNC5b mRNA in normal HUAEC as well as activated HUAEC.

RESULTSIn situ hybridization results showed that UNC5b mRNA expression was detected majorly in endothelial cells of all normal liver tissues, and partial PCLTs but was weak or even undetectable in endothelial cells of the corresponding HCC tissues. The expression levels of UNC5b gene in PCLTs were significantly correlated with capsular formation of HCC. Furthermore, RT-PCR results showed that the expression levels of UNC5b mRNA in activated HUAEC were significantly higher than those in normal HUAEC.

CONCLUSIONSDown-regulation of UNC5b gene expression is related to angiogenesis of HCC, which may be associated with the progression of HCC.

Objective To analyze the genetic characterization of VP1 region of Coxsackie virus A10(CVA10)isolated from clinical specimens of hand, foot and mouth disease(HFMD) patients in Shandong Province. Methods Clinical specimens were collected from some of HFMD patients from 2008 to 2009. The virus was isolated by cell culture. Total RNA was extracted, and the VP1 genes of the isolates were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and sequenced. The genotypes were identified by molecular typing method and bioinformatics analysis.Homologous comparison and phylogenetic analysis of representative CVA10 strains were performed.Homologous comparison between the Shandong isolates and strains obtained from GenBank were performed and phylogenetic analysis of some representative CVA10 strains were performed. Results Three hundred and thirty viruses strains were isolated from 760 clinical specimens collected from HFMD patients, and 17 of them were identified as CVA10. The homologies of nucleotide and amino acid of the 17 CVA10 strains were 82.3%-100.0% and 94.2%-100.0%, respectively. Compared with the prototype strain of CVA10 (Kowalik/USA/2003), the homologies of nucleotide and amino acid were 75.6%-76.8% and 90.2%-93.2%, respectively. Interestingly, Shandong CVA10 strains were clustered into two distinct subgroups in the phylogenetic tree. Conclusions CVA10 is one of the causative agents of HFMD. Two independently circulating subgroups of CVA10 exist in Shandong province.
