ObjectiveTo investigate the effect of nickel-titanium(Ni-Ti) shape memory alloy embracing internal fixer on oblique or spiral fracture.Methods23 cases with spiral or oblique fracture accepted internal fixation with Ni-Ti shape memory alloy embracing.The time of bone healing,articular function,the appearance and function of the wound extremity were evaluated after 9～34 months follow-up.ResultsAll fractures healed in 4～16 weeks after operation.None infection,nonunion,embracing emersion or break had been found. The fine rate was 91.3%.ConclusionThe effect of Ni-Ti shape memory alloy embracing internal fixer on long spiral or long oblique fracture is satisfactory.

Academe hash't got the same view about science attribute of traditional Chinese medicine(TCM)up to now.This article demonstrates the scientific attribute of the traditional Chinese medicine from the nature of science,the seientific attribute of medical science and the relationship between the traditional Chinese medicine and medical science.TCM needs development.In order to develop the traditional Chinese medicine quickly,on the basis of inheriting tradition,we should make the best use of modem scientific technology.Not simply copy the theories and methods of western medicine but using the scientific measurement to build up the measurement of TCM symptoms,the relationship between symptoms and the change of the body,explore the process of physiology and pathology,and combine with western medicine to develop a mature science-medical science.

The realization of symptom measurement of the traditional Chinese medicine is a must for the development of traditional Chinese medicine, which obtained a common acceptation academically. This article believed the methods for realizing symptom measurement are the combination of both TCM two basic theories of "the wholism conception" and "treatment based on syndrome differentiation" and modern scientific measures and methods. Meanwhile, the western medicine should be simply excluded, other than simply compare a TCM syndrome to a physiological and biochemical indicator of western medicine.

The progress of objective and digital diagnosis of Traditional Chinese Medicine (TCM) is not optimistic.There is no denying that there are a lot of research ideas and methods,on the other hand,the understanding of TCM is very one-sided,fuzzy and even wrong.This paper attempts to absorb the quintessence of TCM in clinical medical information detection and treatment ideas from the measurement science and modem information detection and processing point of view.Ideas and means of clinical medical information detection and treatment in TCM not only coincide with,but also improve that of modem information detection and processing way and means,which have high reference value.The way of thinking and means,not only for medical information detection and processing,but also provide a valuable reference for other areas of information detection and processing.

To construct a lentiviral shRNA vector targeting human protein phosphatase 1D magnesium-dependent (PPM1D) gene and detect its effectiveness of gene silencing in human gliomas, specific siRNA targets with short hairpin frame were designed and synthesized. DNA oligo was cloned into the pFU-GW-iRNA lentiviral expression vector, and then PCR and sequencing analyses were conducted to verify the constructs. After the verified plasmids were transfected into 293T cells, the lentivirus was produced and the titer of virus was determined. Real-time quantitative PCR and Western blot were performed to detect the PPM1D expression level in the infected glioma cells. PCR and Western blot analyses revealed the optimal interfering target, and the virus with a titer of 6×10(8) TU/mL was successfully packaged. The PPM1D expression in human glioma cells was knocked down at both mRNA and protein levels by virus infection. The expression of PPM1D mRNA and protein was decreased by 76.3% and 87.0% respectively as compared with control group. The multiple functions of human glioma cells after PPM1D RNA interference were detected by flow cytometry and cell counting kit-8 (CCK-8). Efficient down-regulation of PPM1D resulted in significantly increased cell apoptosis and reduced cell proliferation and invasion potential in U87-MG cells. We have successfully constructed the lentiviral shRNA expression vector capable of stable PPM1D gene silencing at both mRNA and protein levels in glioma cells. And our data gave evidence that the reduced cell growth observed after PPM1D silencing in glioma cells was at least partly due to increased apoptotic cell death.

Objective To evaluate the value of stress perfusion cardiovascular magnetic resonance in the diagnosis of coronary ar-tery disease.Methods Relevant literatures about stress perfusion cardiovascular magnetic resonance in the diagnosis of coronary ar-tery disease were searched.According to the recommended contents of the Cochrane Collaboration,we set inclusion criteria and screen literatures.Using software STATA 12.0 and Meta-disc 1.4,we analyzed the data ,including the heterogeneity,publication bias,subgroup analysis,Meta-regression,clinical application,pooled sensitivity(SEN),specificity(SPE),positive likelihood ratio (PLR),negative likelihood ratio(NLR),diagnostic odds ratio(DOR)and 95%confidence interval(95%CI),we drew the summary receiver operating characteristic curve(SROC)and calculated the area under the curve(AUC).Results Twenty-nine literatures were included,the pooled SEN,SPE,PLR,NLR,DOR and 95%CI were 0.90(0.89~0.92)、0.78(0.75~0.80)、4.03(3.32~4.91)、0.14 (0.11~0.18)、32.54(22.25~47.60)respectively.The AUC of SROC was 0.907 8.Conclusion The current evidence indicates that stress perfusion cardiovascular magnetic resonance has a high diagnostic accuracy for detection coronary artery disease.However, the relatively high false positive rate was found due to the medium specificity.

Objective To investigate the clinical features and changes of the patients with colorectal polyps in the recent 5 years of the Central Hospital of Jiangjin district.Methods Inpatients and outpatients with colorectal polyps found by colonoscopy were collected from January 2011 to December 2015 in Central Hospital of of Jiangjin district.Index of each patient's gender,age,the location,size,number and pathological results of each enrolled.Then the data were analyzed statistically.Results Patients with colorectal polyps in the ratio of male to female was 1.56:1(P＜0.05),middle and old aged group multiple (compared with the young group,P＜0.05);left half colon accounted for 53.0 ％ (P＜0.05),48.0 ％ of them were single shot,diameter≤ 1 cm accounted for most.Adenomatous polyp accounted for 71.0％,most of them were tubular adenoma (54.0％).29.9％ of patients with colorectal polyps had abdominal pain,29.0 ％ changed in bowel habits and traits,only 6.7 ％ of the patients had typical hematochezia.Conclusion According to the anlysis results there's no obvious changes happened on the clinical features of colorectal polyps in the past 5 years.
