ABSTRACT
Objective:To observe the functional remodeling of the default mode network (DMN) of patients with post-stroke cognitive impairment (PSCI) in response to transcranial direct current stimulation (tDCS) and to explore the mechanisms involved.Methods:Eighteen PSCI patients and twenty healthy controls were enrolled. The PSCI patients were given 20 minutes of tDCS at 2.0mA on the dorsolateral prefrontal cortex every weekday for four weeks. The subjects were scanned using resting state functional magnetic resonance imaging before and after the intervention to explore any functional changes in the DMN. Montreal cognitive assessment (MoCA) scoring was performed before and after the treatment.Results:Compared to the healthy controls, the cognitively impaired patients showed significant abnormalities in the DMN on admission, including decreased functinal connection (FC) in the posterior cingulate cortex and/or precuneus (PCC/PCu), as well as increased FC in the medial prefrontal cortex (MPFC) and left hippocampus. After the treatment, a significant improvement in the PSCI patients′ average MoCA score was observed. The average FC of the PCC/PCu had also increased significantly, while that of the left hippocampus had decreased significantly, on average. The FC in the PCC/PCu after tDCS was found to be positively related to the MoCA score measured at 4 weeks after admission.Conclusions:PSCI patients show functional abnormalities in the DMN. tDCS applied to their dorsolateral prefrontal cortex can significantly improve their average MoCA scores, which may be related to the increasing FC of the PCC/PCu.
ABSTRACT
Objective To compare the effectiveness of cerebral palsy rehabilitation patterned on the children and youth version of the international classification of functioning,disability and health (ICF-CY) with traditional patterns.Methods Two children's rehabilitation wards were selected as the ICF-CY group and the control group.The children in the former group were evaluated using the ICF-CY and provided with individual rehabilitation plans according to their evaluation results,while those in the latter group were given traditional rehabilitation without any evaluation.Before and after 3 courses of treatment,both groups were assessed using the pediatric evaluation of disability inventory (PEDI) and the gross motor function measure (GMFM),and their use of assistant devices was assessed.Results After three courses of treatment the ICF-CY group's average PEDI score had improved significantly and was superior to that of the control group.Significant improvement was observed in the GMFM scores in both groups after the treatment,with no significant inter-group differences.Significantly more of the children in the ICF-CY group used the assistive devices (except the lower limb orthoses) compared to the control group.Conclusion Therapy based on the ICF-CY is obviously superior to traditional rehabilitation planning.
ABSTRACT
Objective To investigate the expression and clinical significance of lactate dehydrogenase A (LDHA) in breast cancer.Methods Tissue samples of 76 breast cancers and corresponding paired adjacent normal tissues were collected and made into tissue micrcarrays (TMAs).Immunohistochemistry (IHC) analysis was performed to detect the expression of LDHA and further analyzed the correlation of LDHA expression and clinicopathological variables and prognosis of breast cancers.Results LDHA was frequently upregulated in breast cancer tissues compared to the normal breast tissues (P ＜ 0.05).High LDHA expression was associated with distant metastasis (P ＜ 0.05) and worse patient prognosis (P ＜ 0.05).Conclusions LDHA is closely related to the occurrence and clinical progress of breast cancers.LDHA might be a potential novel molecular marker for diagnosis,prognosis and therapy in breast cancers.
ABSTRACT
Objective To investigate the application of the three-dimensional reconstruction for the random flap.Methods The bones,muscles,fascia,skin and vessels in eleven patents were reconstructed by the MIMICS 10.01 CT angiography (CTA) scanning,and the single artery and its branches were gained by the subdivision of the vessels.3D-images were shown respectively and jointly.Results Arterial reconstruction images were clearly displayed by 3D workstation CTA and if they were combined with the original cross-sectional images and vessel analysis software,they were able to accurately evaluate the location,range,degree of artery,the distal outflow tract.The vessels and soft tissue displayed in the software could show detailed distribution of the vessels in one region and this could provide the accurate anatomical basis for the random flap and the design of the operation.This method could easily meet the preoperative design demands and also had the guiding significance for postoperative evaluation.Conclusions The method of 3D-reconstruction is very good for studying the random flap and the design of the operation.
ABSTRACT
Objective To observe the effects of conductive education on gross motor function and Gesell development test results in children with cerebral palsy.Methods One hundred and thirty-eight children with cerebral palsy were stratified randomly according to the gross motor function classification system (GMFCS) and sexes into two groups:the conductive education group received conductive education combined with general comprehensive rehabilitation,the control group received general comprehensive rehabilitation only.After 4 months of training,the results of both groups in terms of gross motor function and Gesell development test results were compared.Results The GMFCS evaluation results of the 2 groups were compared through covariance analysis (F =4.479,P =0.036 ＜0.05),the result of conductive education group was better than that of control group; in both groups the result after training was superior to that before training.For Gesell development test results comparison,the differences between conductive education group and control group were statistically significant (P ＜ 0.05) ; the result of conductive education group was better than before the training (t =24.93,P =0.00 ＜ 0.05) ; but in control group the difference between the results before and after training was not significant (t =13.34,P ＞ 0.05).Conclusions Conductive education could improve gross motor function and whole body development.
ABSTRACT
Objective To investigate the expression of miR-185 in breast cancer and its clinical significance.Methods miR-185 expression was detected in 132 cases of breast cancer and 51 cases of benign breast lesions.The correlations of miR-185 ex pression with the clinicopathologic characteristics,overall survival,and disease-free survival of breast cancer patients were analyzed.Results miR-185 was down-regulated in the breast cancer tissues relative to control tissues.The down expression levels of miR-185 cases were found to be significantly associated with tumor node metastasis (TNM) stage,local relapse,and distant metastasis (P ＜ 0.05).Conclusions miR-185 was associated with carcinogenesis,progression,and prognosis of breast cancer and it might be used as a potential target of therapy and a biomarker of diagnosis and prognosis of breast cancer in the future.

ABSTRACT
Objective To study the function of hypoxia mimics of different exposure time of deferasirox in improving the growth of micrangium in a narrow pedicle flap.Methods Fourty male SD rats were divided into 2 groups:experimental group was fed with deferasirox 100 mg/kg per day from 1d,3d,5d and 7d,respectively,before the surgery of transferring the narrow pedicle flap,while control group just fed with saline.After 7 days,the immunohistochemistry,Western blot and quantitative reverse transcription-PCR (qPCR) were performed to examine the expression of CD34.qPCR was used to examine the expression of HIF-1α,VEGF in order to investigate the regulatory effect of deferasirox in improving the growth of micrangium and the distinction among the different exposed time of deferasirox in the narrow pedicle flap.Results The deferasirox group exhibited a marked improvement in flap healing time,and with the increasing administration time of deferasirox,the expression of MVD,HIF-1α and VEGF was improved in each treated group (P＜0.05).Conclusions Deferasirox can induce HIF-1α secretion and increase CD34 expression,and so deferasirox can protect endothelial cells from hypoxic and ischaemic injury.
ABSTRACT
Objective To investigate the application and survival mechanism of a long and narrow pedicle flap which was used to repair the tissue defects after removal of tumor in aged patients.Methods The long and narrow pedicle flap was designed with its pedicle located beside wound surface along the pathway of well-known or perforating branch blood vessel to repair the defect caused by removing the tumor in aged patients.The size of the flaps ranged from 3 cm × 4 cm to 10 cm × 12 cm.The length and width of the pedicle ranged 2 - 8 cm and 1.0 - 1.5 cm.Results This flap was used in 17 cases.The flap was survived well in 14 patients,and healed later in other 3 patients because of wrong bandaging in earlier period.Conclusions The capability of bearing ischemia and hypoxia of the flap tissue is stronger after transfer owing to low metabolic rate in the skin tissue in aged patients.The flap is easily survived by repairing the tissue defects after removal of tumors in aged patients with the long and narrow pedicle flap.The pedicle of flap is narrow and long,and the transposition of the narrow pedicle flap is easy.The postoperative appearance is satisfactory.It is an ideal choice for repairing the defect caused by removal of tumor in aged patients.
ABSTRACT
Objective To introduce a new and practical method of treating blepharoptosis with direct suspension of the frontal muscle-fascia improvement. Methods 22 cases of blepharoptosis were corrected by direct suspension of the frontal muscle-fascia in which the dynamia still came from frontal muscle.Through double-fold eyelid incision, the frontal muscle-fascia was dissected from the subcutaneous tissue and a 1.5 cm length incision of the frontal muscle-fascia was cut under the supraorbital margin. And through the incision, the frontal muscle-fascia on the superficies of periosteum was dissected 1.5 cm to the upper margin of orbital, and then the frontal muscle-fascia was pulled down and fixed to the levator muscle aponeurosis directly by mattress sutures, with the tension being adjusted to a moderate degree. Results 22 cases of blepharoptosis were cured by primary healing with this method. The patients were followed up for 3 to 6 months with satisfactory results and no recurrence. Conclusion Compared with the traditional methods,this one may decrease the damage to the upper lid and frontalis area, leaving no risk of damaging the vessels or nerves. The technique is simple and the curative effect is affirmed. It can be used to treat any blepharoptosis patient with normal frontal muscle function.

ABSTRACT
Objective To evaluate the effects of impaired glucose tolerance (IGT) on ventricular remodeling. Methods Parameters of every subject including left ventricular mass ( LVM), left ventricular mass index (LVMI), E/A ratio, 75 g oral glucose tolerance test (OGTT), ambulatory blood pressure monitoring(ABPM) data including 24-hour mean systolic blood pressure(mSBP) and 24-hour mean diastolic blood pressure(mDBP) were collected. Then the relationship of IGT and myocardial remodeling related parameters were analyzed. Results The rate of diastolic dysfunction was higher in the IGT combined with hypertensive group(74% ) compared with the hypertensive group( 39% )( x2 = 6. 5, P ＜ 0. 05 ). The rate of diastolic dysfunction was higher in the IGT group( 34% ) compared with the normal group( 10% ) (x2 = 5.2,P ＜0. 05). The rate of Left Ventricular Hypertrophy (LVH)in the IGT combined with hypertensive group (24%) was higher than the other three groups (Hypertension group 7%, IGT group 0, Normal group 0) (x2 =4.561,P ＜0.05), and there was no significance between the rest three groups (P ＞0.05).Stepwise multiple regression showed age and 2 Hours' Postprandial Blood Glucose were independent risk factors of E/A ratio. Conclusions These results suggested that IGT is a possible contributor to left ventricular hypertrophy and diastolic dysfunction, and is one of the histopathology of left ventricular remodeling.
ABSTRACT
Objective A meta-analysis of clinical trials of prehospital thrombolysis versus in-hospital thrombolysis or PCI for acute myocardia infarction (AMI). Method We collected the literature on prehospital thrombolysis for AMI published at home and abroad from January 1989 to April 2009. Recanalization rate of infarct-related arter, complication incidence and mortality ( ＜ 30 d) were regarded as result indicators. Software RevMan 4.2.8 was used to process meta-analysis. Results There were only 27 literatures selected. Prehospital thrombolysis was associated with higher recanalization rate of infarct-related arter[OR 2.67,95%CI(1.86 ～ 3.85);P ＜0.01] and lower mortality ( ＜ 30 d ) [OR 0.71,95%CI(0.64 ～ 0.78); P ＜ 0.01] than in-hospital thrombolysis. There was no significant difference in complications between them. Compared with PCI, prehospital thrombolysis was associated with higher complication incidence [OR 2.91,95% CI ( 1.26 ～ 3.80); P = O.005]. There was no significant statistical difference of mortality ( ＜30 d ),but the sensitivity analysis was not good. Conchusions The effect and prognosis of prehospital thrombolytic are superior to that of in-hospital thrombolysis,and the same with PCI,but prehospital thrombolytic has higher incidences of complications,and the sensitivity is not good.
ABSTRACT
Objective To reveal the relationship between a certain ratio of the length to width of a slender narrow pedicle and random flap in survival area with an experimental study. Methods 25 pigs were randomly divided into 5 groups. The ratio of length to width of slender narrow pedicle in 5 groups was different and every ratio's slender narrow pedicle was carrying 5 different sizes of random flaps. In each group, these 5 flaps were created randomly in each pigs' bilateral back. The flaps were evaluated with the general observation, fluorescence examination, blood flow ECT test, and computerized analysis of survival area. Results When the ratio of the length to width of the slender narrow pedicle was constant, along with the flap area increased, the flap survival area also increased, but when the flap reached a certain area, the distal flap would develop necrosis, the flap survival area would not reduce; when the flap size remained unchanged, along with the ratio of the length to width of the slender narrow pedicle increased, the flap survival area was not affected, but, when the ratio of the length to width of the slender narrow pedicle increased to a certain limit, distal flap would lead to necrosis, and the flap survival area would reduce. Conclusion The slender narrow pedicle flap is a new and practical random flap. The pedicle of random flap can be designed as slender shape, and the ratio of pedicle width to flap length is far less than traditional ratio. Increasing the flap size or ratio of the length to width of a slender narrow pedicle in a certain extent will not lead to flap necrosis.
ABSTRACT

Methods Hair removal was performed in 607 hirsute patients with two long-pulsed lasers. Results Although the effectiveness rates of hair removal in upper lip and full bread were not different, their complications were different by using two long-pulsed lasers. Also there were signifi-cant decreases of effectiveness and complication in the lighter skin and thc darker skin (P<0.01). Con-clusion The 755 nm wavelength has more effectiveness and lower complication in the lighter skin. How-ever, the 1 064 nm wavelength has more effectiveness and lower complication in the darker skin.
ABSTRACT
Objective To investigate the value of the new method with bilateral lip mueosa flaps for central defect reconstruction of upper-lip vermilion. Methods On both sides of the central defect of upper lip vermilion, reverse triangular flaps was designed below the junction between vermilion and mucosal. These two flaps had the common pedicle of vermilion depression site. Incisions of "(λ)" shape were de-signed below the defect area and the flaps included mucosa and submucous tissue. This mueosa flaps were raised and orbicularis otis muscles under the flaps were free moderately. Bilateral orbicularis oris muscles were sutured under the common pedicle of the two mucosa flaps. Then the bilateral mucosa flaps were ro-tated down 90° and inserted into the " (λ)" shape incisions to increase the tissue volume of the middle upper lip and deepen the labiogingival sulcus. The common pediele of the bilateral mucosa flaps was formed to the vermilion tubercle and then the incisions were sutured layer by layer. Results The technique was per-formed on 26 patients including 18 cases of upper-lip vermilion defect after repair of bilateral cleft lip,4 ca-ses of upper-lip vermilion defect after repair of unilateral cleft lip and 4 cases of congenital malformation. All the lip mucosa flaps survived completely without any complications. The vermilion, tubercle and shape of the lips were satisfactory after all cases were repaired and all incision scars were concealed. Con-clusions Using the lip mucosa flaps transfer to repair vermilion defect with the same tissue can obtain satisfactory appearance. The lip mucosa flaps are ideal for repairing of the lip vermilion defect and recove-ring of the profile of labial arch and vermilion tubercle. It can be used widely in any cases with the central defect of upper lip vermilion.
