Objective To investigate the effect of acupuncture combined with human amniotic mesenchymal stem cells ( HAMCs ) transplantation on the osteoporosis in ovariectomized rats.Methods Forty-five healthy female non-pregnant Wistar rats were randomly divided into sham operated group, model group and experimental group ( acupuncture+HAMC transplantation), 15 rats in each group.At 7 days after the surgical wound healing, the rats received acupuncture every day and intravenous injection of HAMCs suspension ( except the sham operated group) once a week for consecutive 12 weeks.The body weight was measured every week.24 hours after the last intervention, the rats were killed and specimens were collected.Specimens of the mid-, proximal-and distal femur were taken to measure the bone mineral density using a dual energy X-ray absorptiometer.At 12 weeks after the intervention, changes of the expression of serum 25-hydroxy-vitamin D (25-HVD), C-terminal peptide of type I collagen (CTX-I), bone specific alkaline phosphatase ( BAP) and human tartrate-resistant acid phosphatase 5b ( TRACP 5b) were determined by ELISA, the biomechanical properties of the removed femur was measured, and the expression of transforming growth factor-β( TGF-β) in the vertebrae was assessed by RT-PCR assay.Results Body weight of rats in the sham operation group was increased gradually in accordance with the natural growth of animals, that of the model group was significantly higher than that of the sham operated group since two months after modeling, and the body weight of the experimental group was similar to that of the sham operated group.The bone mineral density and calcium content of the model group were significantly decreased compared with that of the sham operated group ( P<0.05) , and the bone mineral density and bone calcium content of the experimental group were significantly higher than that of the model group ( P <0.05 ) .The ELISA showed that the expressions of serum 25-HVD, CTX I, BAP, and TRAP5b in the model group were significantly lower than that of the sham operated group, and those of the experimental group were significantly higher than that of the model group ( P<0.05 ) . Measurement of biomechanical properties showed that the limit load, limit stress and elastic modulus of the femur of the sham operated group were significantly higher than that of the model group ( P<0.05 ) , and the limit load and elastic modulus of the experimental group were significantly higher than that of the sham operated group ( P <0.05 ) .T-PCR showed that the expression of TGF-β1 m-RNA in the experimental group was significantly up-regulated than that of the sham operated and model groups ( P<0.05) .Conclusions Acupuncture combined with human amniotic mesenchymal stem cell ( HAMCs) transplantation has a synergistic effect on the treatment of osteoporosis, and can improve the conditions in ovariectomized rats.

ObjectiveTo analysis the clinical characteristics and the high risk factors of children with cerebral palsy.MethodsClinical data of 100 children with cerebral palsy were retrospectively analyzed.Results51% of children were born with asphyxia, 42% were born prematurely, 39% were low birth body weight. 85.7% of children involved had mental retardation, 12% had hearing loss and 7% had visual impairment. 88% of children involved had abnormal cranial CT results and 46.1% had abnormal EEG. 50.0% of the children had abnormal brain stem auditory evoked potentials.ConclusionAsphyxia, prematurely birth and low birth body weight are high risk factors of cerebral palsy. Most of the children with cerebral palsy in this group are mental retarded.

Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

Objective To study the effects of mild hypothermia on nervous cell apoptosis and activity of Caspase - 3 after hypoxia -ischemia brain damage (HIBD) in neonatal rats. Methods Seven - day SD rats were divided into sham operation group,normothermia HIBD group (HIBD group) and mild hypothermia HIBD group(mild hypothermia group). In HIBD group,the left carotid of rats was ligated and animals were exposed to 8% oxygen for 2 h.and in mild hypothermia group,hypothermia of 31 - 32 1C lasting 8 hours was used just after HIBD. L sing methods of TUNEL and AC - DEVI) - AMC, the apoptotic cell rate and Caspase - 3 activity level were determined in sham operated group, HIBD group and mild hypothermia group separatively. Results The apoptotic cell rate and Caspase - 3 activity level were significantly lower in sham - operated group and mild hypothermia group than those in HIBD group. Conclusion One of the mechanisms of brain protection by mild hypothermia may be contributed to the decrease of neural cell apoptosis and the activity level of Caspase 3 HIBD.

Objective To define the significance of the anatomical division and features of popliteal artery in popliteal angioplasty.Methods This study involved 118 lower limbs in 113 cases of femoropoliteal occlusive disease undergoing angioplasty in our center between August 2011 and July 2013.A bent-knee angiogram was taken before recanalization of the lesion.The flexion pattern and the location of flexion points of popliteal artery were collected to study their relationship with the division of popliteal artery.A post-procedural bent-knee angiogram was taken in case of popliteal stenting to assess any change in flexion angulation and distal flow.Results There are diverse flexion patterns in popliteal artery,75.4％ of the flexion points locate in P2 segment,18.6％ in P1,and 6.0％ in P3.On post-procedural bent-knee angiogram in 73 cases of popliteal stenting,10 had a more acute distal flexion angulation,distal artery kinking was observed in another 6 cases of which 5 had compromised distal flow.Artery kinking only occurred in cross-flexion-point stenting.Conclusions A better understanding of the division and anatomical features of popliteal artery can be obtained via bent-knee angiogram.This is of value to angioplasty for lesions in different popliteal divisions.

Objective To explore the significant risk factors in patients with Tile C pelvic frac-tures.Methods We conducted a retrospective review of all patients with Tile C pelvic fractures in Nanjing First Hospital from January 2010 to December 2014.The data gathered on each patient in-cluded:age,sex,mechanism of injury,visiting time after injury,shock index,Injury severity scale (ISS),Revised trauma score (RTS),Glasgowcoma scale (GCS),lowest PaO2/FiO2 ,6 h lactate clearance rate,concomitant injures and interventious of Tile C pelvic fractures.The data were tested using Student’t-test,χ2 test and logistic regression method.Results The study include 139 consecutive patients.The total mortality was 29.5%.Among them,36 (25.9%)patients died within 48 hours after admission.Multivariate regression analysis showed that shock index (OR=2.591,95%CI 1.041-4.216), ISS (OR = 47.96,95%,CI 15.89-147.23 ),RTS (OR = 6.917,95% CI 1.147-13.862 ),GCS (OR =4.172,95%CI 2.962-6.268),lowest PaO2/FiO2 (OR= 117.016,95% CI 51.011-176.032),6 h lactate clearance rate (OR=2.785,95%CI 1.191-4.892),concurrent head (OR=6.302,95%CI 2.270-13.175)or chest (OR=12.233,95%CI 5.193-33.985)injures were associated with high morality of Tile C pelvic frac-ture (P <0.01).The performing digital subtraction angiography with intravascular embolization can cut the mortality (OR=0.887,95%CI 0.875-0.899).Conclusion In our study,high trauma score,serious shock, coma,PaO2/FiO2 decreased and 6 h lactate clearance rate decreased,combined with the head and chest inju-ry are the important reasons of mortality in patients with Tile C pelvic fracture.It’s vital to control shock actively,use trauma scale and emphasize multidisciplinary cooperation to reduce mortality in patients with Tile C pelvic fractures.
