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 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 evaluate the clinical value of eversion carotid endarterectomy in patients with carotid atherosclerosis stenosis. Method Summarized the clinical data of 20 patients who accepted eversiou carotid endarterectomy from March 2009 to August 2009, compared the outcomes with preoperative and postoperative image learnt materials and clinical symptoms. Results All cases finished successfully. All clinical symptoms were improved after operation. The stenosis were all improved completely on the image after operation. Conclusions Eversion carotid endarterectomy is safe, effective, and shortening operative time and hospitalization time. It has low restenosis rate, thicken endometrium and plaque can be stripped completely.

The maxillary first premolar is a transitional tooth between incisors and molars. Most maxillary first premolars have 2 root canals. However, the bilateral maxillary first premolar with 3 roots and 3 canals has not been described. This article reports a rare case:The bilateral maxillary first premolar with 3 roots and 3 canals.

BACKGROUND:There were stil lacking related clinical researches in the aspects of whether the total blood loss and hidden blood loss were connected with pathogenesis, whether the total blood loss and hidden blood loss were different among the patients who conducted total hip arthroplasty under different pathogenesis, and whether the preoperative intervention should be conducted for a particular cause? OBJECTIVE:To compare and analyze the hidden blood loss of patients with hip osteoarthritis and femoral neck fracture after total hip replacement. METHODS:The clinical data of 150 patients who received the unilateral total hip arthroplasty treatment from June 2013 to January 2015 were colected and analyzed, including 54 patients with hip osteoarthritis (30 male cases and 24 female cases ), 96 patients with femoral neck fracture (41 male cases and 55 female cases). The pre-and post-operative blood routine and intro-and post-operative blood loss and transfusion were recorded, and hidden blood loss during pen-operation period was evaluated. RESULTS AND CONCLUSION:Total blood loss was (1 616±216) mL, hidden blood loss was (699±102) mL, and hidden blood loss accounted for 43.3% of the total blood loss. The total blood loss was (1 742±254) mL in the hip osteoarthritis group, hidden blood loss was (758±127) mL, hidden blood loss accounted for 44.6% of the total blood loss; The average total blood loss was (1 470±189) mL in the femoral neck fracture group, hidden blood loss was (625±98) mL, hidden blood loss accounts for 42.1% of the total blood loss. The total blood loss and hidden blood loss in hip osteoarthritis group were significantly higher than those in the femoral neck fracture group (P< 0.05). However, there was no significant difference on the hidden blood loss accounts for the proportion of the total blood loss between two groups (P=0.419 3). These results suggest that the total blood loss and hidden blood loss are different for the patients who underwent total hip arthroplasty in the premise of both pathogenesis. Therefore, before the total hip arthroplasty, we should fuly take into account the primary cause of patients and estimate the total blood loss and hidden blood loss, so as to take appropriate preventive measures in time to ensure the safety of the replacement process.
