Great Acupuncture is a special method to treat stroke patients on the relative health side, which reflects the whole view of the traditional Chinese medicine. With more and more clinical controlled trials reported recently, the origin, development and possible mechanisms of great acupuncture are worthy discussed for providing a neoteric method to treat cerebral apoplexy. The differences of great acupuncture and contralateral collateral needling were analyzed in this paper. Indications and attentions of great acupuncture were also summarized. Through comparing between the treatment of cerebral apoplexy by the great acupuncture and related techniques of the modern neurological rehabilitation, we found that the modern rehabilitation techniques focused on promoting the activities of the injured limbs, which might be much weaker in therapeutic intensity than great acupuncture. Therefore we believed that the concept of the great acupuncture of the traditional Chinese medicine is much advanced.

Objective:To establish a glioma cell line U251 stably expressing programmed cell death 4(PDCD4)gene,and to observe the influence of exogenous PDCD4 gene on the proliferation and cell cycle of U251 cells.Methods:Recombinant eukaryotic expression vector pEGFP-PDCD4 was transfected into human glioma cell line U251 by Lipofectamine 2000,and the U251 cells stably expressing PDCD4 were established by G418 selection.Reverse transcription polymerase chain reaction(RT-PCR)and Western blotting were employed to detect the expression of PDCD4 mRNA and protein.Furthermore,cell proliferation and colony forming ability were determined by cell counting and colony formation assay;the cell cycle was detected by FACS.Results:High expression of PDCD4 mRNA and protein was observed in U251 cells transfected with pEGFP-PDCD4,whereas no PDCD4 mRNA and protein expression was detected in the non-transfected and vector-transfected cells.Further,cells transfected with pEGFP-PDCD4 grew more slowly and had lower colony formation rate than cells of the other two control groups(P

Acute kidney injury is a clinical common disease,but it is a dangerous illness with higher o-verall mortality.Even mild renal insufficiency carries complications.Therefore,it is very important for the early diagnosis of acute kidney injury,which is based on high sensitivity,strong specificity of biomarkers.

MicroRNAs (miRNAs) are short non-coding RNAs that regulate gene expression at the post-transcriptional lev-el and then affect important physiological and pathological processes. Many microRNAs are tissue or organ-speciifc which make it possible for them to become potential biomarkers. Similarly, microRNAs are important for physiological functions of kidney and they are involved in various renal disorders. The review summarizes current information about microRNA effect on various kidney diseases, in order to provide references for the diagnosis and treatment of kidney disease in the future.

OBJECTIVE To explore the expression pattern of AQP1,AQP4,AQP5 in the normal middle ear in guinea pigs and its roles in the water homeostasis in the middle ear cavity.METHODS Reverse transcription polymerase chain reaction(RT- PCR),Western blotting and immunohistochemical staining were used to detect AQP1,AQP4,AQP5 in mucosa of the bullae of normal guinea pigs.RESULTS Reverse transcription-polymerase chain reaction and immunoblot analyses revealed that mRNAs encoding AQP1,AQP4,AQP5 were expressed in middle ear membrane of the guinea pigs.AQP1,AQP4 was also detected as 28-kDa,33-kDa proteins in middle ear cavity of guinea pig.Immunohistochemical staining showed that only AQP1 located at capillary endothelial cells and fibroblasts of the submucous layer,as well as at flat and cubical epithelial cells.CONCLUSION The results suggest that AQP1,AQP4,AQP5 can express in the normal middle ear cavity of guinea pigs and may play a vital role in the water transmission in the middle ear.The air-filled middle ear cavity may result from the working of AQP1,AQP4,AQP5.

Objective To investigate the association of risks related to maternal factors with the subsequent development of necrotizing enterocolitis (NEC) in very preterm infants and to determine whether the placental inflammatory lesions were also related to the NEC.Methods This retrospective cohort study examined newborns born at ＜ 32 weeks (n =180) between July 2006 and July 2015 and their mothers at our hospital,recorded the maternal age,body mass index (BMI),multiparity situation,and the usage of prenatal steroids or antibiotics.Medical records of eligible newborns and their mothers were reviewed.Maternal blood white blood cell and differential counts were measured at admission and the placentas were examined histologically after delivery.The primary outcome measure was NEC Bell Stage Ⅱ a.Bivariate analyses and multivariate logistic regression were used for the statistical analyses.Results NEC was diagnosed in 14 of 180 very preterm infants (7.8％),including 11 Stage Ⅱ and 3 Stage Ⅲ infants,and the overall mortality rate of these infants was 7.1％ (n =1).Multivariate regression analysis identified maternal neutrophil-to-lymphocyte ratio (OR =1.07,P =0.002),muhiparity (OR =3.39,P =0.013),and birth weight (OR =0.06,P =0.01) were significantly associated with an increased risk of NEC development.Neonatal neutrophil-to-lymphocyte ratio (NLR) as measured within 24 hours of birth (P =0.65) was not associated with NEC development.Clinical chorioamnionitis (P≥0.99) and histological chorioamnionitis (P =0.46) and funisitis (P =0.21) could not be used as significant predictors of NEC.Conslusions The development of NEC in very preterm infants is associated with the maternal NLR,parity,and birth weight,not with clinical and histological chorioamnionitis and funisitis.

ObjectiveA comparison between intragate and ECG-respiration triggered techniques was performed to determine their differences in measuring the structure and function of the heart at 7.0 T.MethodsTen normal ICR mice aged five to six weeks were examined on a 7.0 T MR scanner.A central slice with papillary muscle included at the short-axis view was scanned with a FLASH-cine bright blood sequence,FLASH-cine black blood sequence,IG-FLASH-sat-cine black blood sequence,and IG-FLASH-cine bright blood sequence.The area of the left ventricle of the end systole and end diastole ( including and excluding the myocardium) was measured with manually outlined ROIs.The increased area of the left ventricle and the myocardium from the end systolic to end diastolic phases was calculated.The signal intensity was measured from 8 ROIs which were evenly located at the myocardium of the end systole,and the mean and standard deviation were then determined.The coefficient of variation ( CV ) was derived by dividing the mean into the standard deviation.ResultsThere was no significant difference ( the increased area of the myocardium t =0,P =1,the increased area of the left ventricle t =2.12,P =0.06) in the function index between the ECG-triggered black blood sequences [the increased area of the myocardium (0.100 ±0.018) cm2,the increased area of the left ventricle (0.060 ± 0.024) cm2] and intragate black blood sequences[the increased area of the myocardium (0.090 ± 0.014) cm2,the increased area of the left ventricle (0.060 ±0.012) cm2].No significant difference(the increased area of the myocardium t =1.56,P =0.15,the increased area of the left ventricle t =2.08,P =0.07 ) in the function index was observed between the ECG-triggered bright blood sequences [the increased area of the myocardium ( 0.100 ±0.018) cm2,the increased area of the left ventricle(0.060 ±0.014) cm2]and intragate bright blood sequences [the increased area of the myocardium (0.090 ±0.019) cm2,the increased area of the left ventricle (0.050 ±0.015) cm2].Furthermore,there was no significant difference(t =1,P =0.34) in the CV of the myocardium signal intensity of bright blood sequences between the ECG-triggering ( 0.050 ± 0.013 ) and intragate (0.040 ± 0.015 ),but significant difference ( t =4.51,P =0.001 ) in the CV of the myocardium signal intensity of black blood sequences between the ECG-triggering ( 0.070 ± 0.033 ) and intragate ( 0.160 ± 0.046 ) was obtained.ConclusionsThe intragate sequences could take the place of the ECG gate sequences in functional analysis of the heart( including bright blood and black blood sequences).The bright blood intragate sequences also could replace the bright blood ECG-triggered sequences in analyzing the signal of the myocardium.
