Objective To evaluate the technique and clinical results of the modular fluted tapered stems for treating periprosthetic femoral fractures in revision hip arthroplasty.Methods From August 2007 to February 2014,fourteen patients (14hips) with periprosthetic femoral fractures underwent revision hip arthroplasty with modular fluted tapered stem.A retrospective analysis was performed involving all patients who were followed-up more than 2 years.The subjects consisted of 4 males and 10 females with mean age of 73.4±6.6 years (range,62-82 years) at the time of revision.All patients were unilateral with 8 left hips and 6 right hips.The status of primary arthroplasty was bipolar hemiarthroplasty in 3 patients and total hip arthroplasty in 11 patients.Nine cases were with cemented stems,5 cases with uncemented stems.The interval from primary hip arthroplasty to revision surgery ranged from 40 to 163 months,with an average of 120.9±31.9 months.Eight cases with Vancouver type B3 periprosthetic femoral fracture were found preoperatively,6 cases with aseptic loosening and bone deficiency occurred periprosthetic femoral fracture during the operation.Based on the Paprosky classification system for femoral bone deficiency:type ⅢA in 8 hips,type ⅢB in 5 hips,type Ⅳ in 1 hip.Both the femoral and the acetabular components were revised in 9 patients.All femoral fractures were treated with cable fixation,and the cortical allograft struts were used to augment femoral bone stock in 7 patients.The patients were followed up at 6 weeks,3 months,6 months,9 months,12 months and annually thereafter.Harris Hip Score System and radiographic examination was used to evaluate the clinical results,including fracture union,implant stability,bone stock,hip joint function and postoperative complications.Results The mean duration of follow-up was 62.1 ±22.2 months (range,30-96 months).The mean times of fracture union were 6.2±2.5 months (range,3-12 months).The Harris Hip Score improved from 29.6± 10.3 preoperatively to 86.3±4.2 postoperatively (t=-21.6,P=0.00).Thirteen cases (93％,13/14) had the stem subsidence of 4.9±2.5 mm (range,0-9 mm).Thirteen cases (93％,13/14) were presented with femoral bony restoration.Two cases showed incorporation of the allograft in 7 patients.One patient developed deep venous thrombosis of lower limbs,and one suffered from subcutaneous hematomas after surgery.There was no infection,aseptic loosening,dislocation or periprosthetic fracture complications at the followup.Conclusion The short-medium term results of the modular fluted tapered prosthesis applied in periprosthetic femoral fractures are encouraging in revision hip arthroplasty.The present technology can provide reliable primary stability and can tolerate minimal subsidence postoperatively.

Objective: To observe the improving effect of muscle regions of meridians needling method on the upper limb function in children with cerebral palsy of spastic hemiplegic type. Methods: A total of 100 children with cerebral palsy of spastic hemiplegia type were divided into a treatment group and a control group according to the visiting sequence, with 50 cases in each group. The control group was treated with conventional rehabilitation plus conventional acupuncture treatment. The treatment group was treated with conventional rehabilitation plus muscle regions of meridians needling method. The electromyography (EMG) signal values of triceps brachii and pronator teres were detected before treatment, and 3 months and 6 months after treatment. The clinical efficacy was evaluated by Peabody developmental motor scale-fine motor (PDMS-FM) and fine motor function measure (FMFM). Results: Three and six months after treatment, the EMG signal values of triceps brachii and pronator teres, grasping scores and visual-motor integrated scores of PDMS-FM and the FMFM scores in both groups increased to varying degrees compared with the same group before treatment, and the intra-group differences were all statistically significant (all P<0.05). Six months after treatment, the results of the above three items in the treatment group were all better than those in the control group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Muscle regions of meridians needling method added on the basis of conventional rehabilitation can effectively reduce the muscle tone of upper limb and enhance the muscle strength, and improve the upper limb function in children with cerebral palsy of spastic hemiplegia type. The efficacy is superior to that of the conventional rehabilitation plus conventional acupuncture treatment.

In this study, we observed the levels of adrenomedullin (ADM) and proadrenomedullin N-terminal 20 peptide (PAMP) in myocardium and aorta of spontaneously hypertensive rats (SHRs) in comparison with Wistar-kyoto (WKY) rats. Contents of ADM and PAMP were measured by radioimmunoassay (RIA) in plasma, myocardium and aorta. The amount of Pro-ADM mRNA of myocardium and aorta was determined by competitive quantitative reverse transcription polymerase chain reaction (RT-PCR). In SHRs the amounts of Pro-ADM mRNA of myocardium and aorta were 66.7% (P<0.01) and 73% (P<0.01) higher than those in WKY rat, respectively. In SHRs, the levels of ADM in plasma, myocardium and aorta were 29%, 76.7% and 79% (all P<0.01) higher than those in WKY rats, respectively. The level of PAMP in SHRs was increased by 42.5% in plasma (P<0.01), 47.2% in myocardium (P<0.0.1) and 27.3% in aorta (P<0.05) compared to WKY rats, respectively. In addition, the ratio of ADM content to PAMP content in SHRs group was increased compared with that in WKY group (2.0+/-0.25 vs 1.64+/-0.3 and 2.2+/-0.18 vs 1.56+/-0.28, in myocardium and aorta, respectively, P<0.01). These results suggest that ProADM gene expression is up-regulated and the increase in ADM and PAMP is different in SHRs. The significance of inconsistency of increase in ADM and PAMP in SHRs needs to be further investigated.

AIM AND METHODSTo observe the effect of myocardial mitochondrial L-arginine (L-Arg)/nitric oxide (NO) system on mitochondrial Ca2+ transport by using purified rat mitochondria and incubation of them in vitro.

RESULTSCompared with control group, incubation of mitochondria with L-Arg (10(-4) mol/L, NO substrate) or sodium nitroprusside (5 x 10(-7) mol/L, the donor of exogenous NO, SNP) increased significantly mitochondrial NO2- (66% and 89%, P < 0.01), respectively, and decreased the Ca2+ content (40% and 54%, P < 0.01). After L-Arg or SNP treatment, mitochondrial Ca2+ uptake were decreased by 67% and 85%, respectively (P < 0.01), vs control. The rate of mitochondrial Ca2+ release decreased by 11% and 8%, respectively (P < 0.01). When L-NAME (NO synthase inhibitor) was incubated with mitochondria and the L-Arg together, it inhibited the effects of L-Arg, NO2 on the mitochondrial NO2 formation, Ca2+ content descending, and decrease of Ca2+ uptake and release.

CONCLUSIONThe data suggest that myocardial mitochondrial L-Arg /NO systems take part in the regulation of cardiomyocytes Ca2+ transportation.

Objective:To observe the clinical efficacy of needling thirteen ghost acupoints for children with autism spectrum disorder. Methods:A total of 90 cases with autism spectrum disorder (ASD) aged between 2 and 6 years were randomly allocated into 2 groups by random number table. The control group (n=45) received routine rehabilitative training, and the treatment group (n=45) received acupuncture at thirteen ghost acupoints plus routine rehabilitative training. The Beijing Gesell developmental (Gesell) scale and autism behavior checklist (ABC) were used to assess the intellectual, language and behavior development before and 3 months after the treatment. Results:After the treatment, the total effective rate in the treatment group was 82.2%, versus 55.6% in the control group, showing a statistical significance (P<0.05). As for the scores of social, emotional and language in Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05), and all the five subscales in the Gesell scale in the treatment group were significantly better than those in the control group (allP<0.05). As for the scores of ABC, there were significant intra-group differences in the treatment group (P<0.05), and the scores in the treatment group were significantly better than those in the control group (allP<0.05). Conclusion: Rehabilitation training plus acupuncture at thirteen ghost acupoints can significantly improve the intellectual, language and abnormal behavior in autism spectrum disorder children.

In genetic modification of plants, once the transformants are obtained, selection markers are no longer required in mature plants. At present, the Cre/lox site-specific recombination system is most widely used to eliminate the selectable marker genes from the transgenic plants. In this study, attempt was made to favour the selection of marker-free plants in the re-transformation method. Green fluorescent protein (GFP) can be directly visualized in living cells, tissues or organisms under UV illumination. This advantage of GFP is exploited in the development of a practical approach in which GFP is used as a visual marker to monitor the removal of the selectable marker gene from transgenic plants. For that purpose, the pGNG binary vector was constructed, in which the GFP gene (gfp) was linked to the expression cassette Nos P-nptII-NosT and the two units were cloned between two directly-orientated lox sites. The CaMV 35S promoter was placed before the first lox site and used to drive GFP expression. The beta-glucuronidase gene (gus) of Escherichia coli was cloned behind the second lox site without a promoter, thus would not be expressed in this position. Tobacco plants were first transformed with pGNG and selected on kanamycin (Kan)-containing media. Regenerated transgenic shoots were readily singled out by GFP fluorescence. The GFP-expressing plants were then re-transformed with pCambia1300-Cre containing hygromycin phosphotransferase gene (hpt) as a selectable marker gene. The Cre-mediated recombination resulted in the elimination of lox-flanked genes, herein gfp and nptII, from the plant genome and brought the GUS gene next to the 35S promoter. Our data demonstrated that transgenic plants free of nptII were easily selected by monitoring the loss of green fluorescence, and at the same time, GUS (here as a target protein) was expressed in the nptII-free plants. Finally, hpt and cre were removed from the progenies of the nptII-free plants by gene segregation.

The purpose of the present study was to explore the expression changes of intermedin/adrenomedullin 2 (IMD/ADM2), a novel small molecular bioactive peptide, and its receptors, calcitonin receptor-like receptor (CRLR) and receptor activity modifying proteins (RAMP1, RAMP2, RAMP3) in the right ventricle of rats with chronic hypoxia-induced pulmonary hypertension. Twenty male Sprague-Dawley rats were randomly divided into 4-week hypoxia group and normal control group (each n=10). The rats in hypoxia group were placed in an isobaric hypoxic chamber, in which O(2) content was maintained at 9%-11% by delivering N(2), and CO(2) content was maintained at <3% for 4 weeks (8 h/d, 6 d/week). The rats in the control group were housed in room air. The protein levels of IMD/ADM2 and adrenomedullin (ADM) in blood plasma and right ventricular tissue were measured by radioimmunoassay. The mRNA expressions of IMD/ADM2, ADM and their receptors CRLR, RAMP1, RAMP2, RAMP3 in right ventricular tissue were determined by reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the ratio of right ventricle weight to left ventricle plus septum weight [RV/(LV+S)] and mean pulmonary arterial pressure (mPAP) were higher in hypoxia group than those in the control group (all P<0.01), suggesting that the rat model of pulmonary hypertension was successfully established. However, the mean carotid arterial pressure (mCAP) between the two groups had no significant difference. Compared with that in the control group, ADM contents in plasma and right ventricular tissue in hypoxia group increased by 1.26 and 1.68 folds (all P<0.01), respectively. Likewise, IMD/ADM2 contents in blood plasma and right ventricular tissue in hypoxia group increased by 0.90 and 1.19 folds (P<0.01), respectively, compared with that in the control group. The data of RT-PCR showed that mRNA levels of ADM, IMD/ADM2 and RAMP2 in hypoxia group increased by 155.1% (P<0.01), 80.9% (P<0.01) and 52.9% (P<0.05), respectively, compared with those in the control group. There were no significant differences in mRNA expressions of CRLR, RAMP1 and RAMP3 between the two groups (all P>0.05). Taken together, the results show that the level of IMD/ADM2 increases in the rats with chronic hypoxia-induced pulmonary hypertension.

OBJECTIVETo observe the alterations of taurine transport, taurine transporter (TAUT) and cysteine sulfinate decarboxylase (CSD) mRNA in the calcification of myocardial cells in vitro.

METHODS3H-taurine measured the amount of taurine uptake. TAUT and CSD mRNA consents were measured using competitive quantitative RT-PCR in cultured and calcified myocardial cells.

RESULTSIn calcification of myocardial cells, taurine concentration was decreased by 27% (P < 0.05), taurine uptake was markedly reduced, Vmax reduced by 39% (P < 0.01), there were no statistical significance of Km values between the two groups. TAUT mRNA decreased by 45% (P < 0.01), but CSD mRNA increased by 25% (P < 0.05).

CONCLUSIONSThe data suggest that there were impediment of taurine transport in calcification of myocardial cells, as TAUT mRNA level was decreased, but CSD mRNA concentration was improved.

The alterations of taurine transport and the expression of taurine transporter (TAUT) mRNA in myocardium and aortic wall were investigated in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats. It was demonstrated that plasma taurine concentration and taurine release from myocardium and aortic wall in SHR were higher than those in WKY rats, whereas taurine content, taurine uptake and TAUT mRNA in myocardium and aortic wall of SHR were lower than those of WKY rats. In SHR, the maximal velocity (V(max)) of taurine transportation in myocardium and aortic wall was lower by 24% (P<0.05) and 35% (P<0.05) than that in WKY, their michaelis constants (Km) values were higher by 16% (P<0.05) and 39% (P<0.05), respectively. The results suggest that there is dysfunction of taurine transport in myocardium and aortic wall in SHR, which may be partly resulted from the decrease of TAUT activity and affinity, and down-regulation of TAUT gene expression.
