Objective To compare the early efficacy of two different ways of rehabilitation exercises in total knee arthroplasty (TKA) patients. Method From January 2011 to January 2014,136 patients having undergone TKA were randomly divided into two groups. In group A , patients exercised under the guidance with doctor. In group B, patients exercised by using continuous passive movement (CPM) machine. Compared the data from the two groups including range of motion (ROM) of the knee joint, knee function score (KFS) and circumference of the knee joint, t test of independent sample was utilized in the research. Results All patientswere followed up in 4 weeks. The ROM and KFS of Group A was significantly better than Group B (P < 0.05). The knee circumference had no statistically significant difference between two groups (P> 0.05).Conclusion Group A and B are effective methods in TKA patients in early rehabilitation training. But training under the guidance of doctor has greater advantages than CPM.

BACKGROUND:Nano-hydroxyapatite/polyamide 66 is a new nanobionic composite material and has good biocompatibility and bone conduction, but after implantation, whether the composite material can bind to vertebral bone interface and whether it is safe in clinical use stil need further studies. OBJECTIVE: To observe the ability of nano-hydroxyapatite/polyamide composite binding to the interface of artificial humeral head. METHODS: The rabbits were randomly divided into two groups: composite group was implanted with nano-hydroxyapatite/polyamide composites; control group implanted with autologous bone. After the replacement, rabbit bone marrow mesenchymal stem cels were subjected to primary culture, and then the cels were co-cultured with the composite material. RESULTS AND CONCLUSION:At 24 hours after culture, bone marrow mesenchymal stem cels grew wel on the composite materials. The cel adhesion rate was significantly higher in the composite group than the control group at 1 and 4 hours after culture (P < 0.05). After co-culture 4.5, 5.5, 6.5 hours, the absorbance value of cels in the composite group was higher than that in the control group (P < 0.05). At 24 weeks after replacement, changing ranges in the proportions of bone tissue and fibrous layers on the implant surface as wel as coverage rate in the composite group were the highest (P < 0.05). These findings indicate that the nano-hydroxyapatite/ polyamide composite implant has a certain binding capacity, which can make a good interface osseointegration.

Objective To evaluate the safety and feasibility of hysteroscopy in the treatment of endogenous type cesarean section scar pregnancy (CSP). Methods Clinical data of 58 cases of CSP from August 2012 to February 2014 in our hospital were analyzed retrospectively.Thirty-one cases were treated by hysteroscopy,while 27 cases were treated by laparoscopy.The intraoperative blood loss,operation time,postoperative hospital stay,postoperative drainage of uterine cavity,β-hCG level resolution time and time to menstruous restoration were compared between the two groups. Results The intraoperative blood loss,operation time,length of hospitalization after operation,and time to menstruous restoration were statistically lower in the hysteroscopy group than those in the laparoscopy group [(109 ±59)ml vs.(143 ±63)ml,t =-2.121 ,P =0.038;(43.7 ±17.5)min vs.(100.8 ±18.8)min,t =-1 1 .974,P =0.000;(3.8 ±0.7)d vs.(4.5 ±0.6)d,t =-4.057,P =0.000;(43.8 ±3.9)d vs.(45.9 ±3.8)d,t =-2.070,P =0.043].There were no significant differences in postoperative drainage of uterine cavity and β-hCG level resolution time between the two groups [(22.1 ±2.8)ml vs.(23.6 ±3.2)ml,t =-1 .904,P =0.062;(20.5 ±7.7)d vs.(22.9 ±9.3)d,t =-1 .075,P =0.287]. Conclusion Hysteroscopy has advantages of less intraoperative blood loss,shorter hospitalization time and quicker recovery in the treatment of endogenous type CSP.

Objective: To observe the effects of needling Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) on cerebral glucose metabolism in patients with vascular dementia (VD) by cerebral functional imaging technique. Methods: Twenty-five patients with VD were divided into 5 groups (Group A, B, C, D and E) randomly. Patients in the Group A were treated by needling routine acupoints for hemiplegia (Acupoints of the three yang meridians of hand and foot), and besides the routine acupoints, patients in the Group B were treated by needling Baihui(GV 20), the Group C by Shuigou(GV 26), the Group D by Shenmen(HT 7), and the Group E by Baihui(GV 20), Shuigou(GV 26), and Shenmen(HT 7). All the patients were examined by Positron Emission Tomography (PET) to detect the cerebral glucose metabolism in the bilateral frontal lobes(orbital gyri), parietal lobes, temporal lobes(hippocampus and hippocampal gyrus), occipital lobes, thalamus, lentiform nucleus, caudate nuclei, cingulate gyms and cerebellum before treatments and after treatments. Results: After needling the routine acupoints for hemiplegia, glucose metabolism increased in lentiform nucleus and temporal lobe;needling Baihui(GV 20), increased in frontal lobe, temporal lobe and lentiform nucleus;needling Shuigou(GV 26), increased in frontal lobe, thalamus and lentiform nucleus; needling Shenmen(HT 7), increased in parietal lobe and lentiform nucleus; and needling these three acupoints, increased in frontal lobe, temporal lobe, thalamus and lentiform nucleus. Conclusion:Needling Baihui(GV 20), Shuigou(GV 26) and Shenmen(HT 7) affect glucose metabolism in different functional regions of the brain, and Baihui(GV 20), Shuigou(GV26) and Shenmen(HT 7) relate to different functional regions of the brain.

Objective To explore the clinical effect of uterine artery embolization on cesarean scar pregnancy (CSP) and curettage opportunity.Methods Sixty-three patients with CSP received curettage after uterine artery embolization with gelfoam were selected.Among of them,21 cases received curettage within 24 h after uterine artery embolization (group A); 20 cases within 1-3 d (group B);22 cases within 4-7 d (group C).The intraoperative haemorrhage,serum β-human chorionic gonadotropin (β-hCG)level resolution time,duration of hospital stay,hospitalization cost,postoperative complications were observed after the termination of the pregnancy.Results The duration of hospital stay and hospitalization cost in group A and group B were (10.5 ± 3.9),(10.2 ± 5.2) d and (7353 ± 962),(7594 ± 1032) yuan,respectively,and there was no significant difference (P ＞ 0.05).Which was lower than that in group C [(13.9 ± 5.4) d,(10 980 ± 1534) yuan],and there was significant difference(P ＜ 0.01).The intraoperative haemorrhage,serum β-hCG level resolution time and postoperative complications in group B and group C were(20.2 ± 8.8),(20.7 ± 9.3) ml and (25.9 ± 9.3),(25.7 ± 8.1) d and 40.0％(8/20),40.9％(9/22),and there was no significant difference(P＞ 0.05).But which was better than those in group A[(35.0 ± 10.7) ml,(20.5 ± 7.7) d,66.7％ (14/21)],and there was significant difference (P ＜0.01).Conclusions The treatment of curettage after the uterine artery embolization is a safe and effective method for CSP.There are fewer complications,shorter hospital stays and fewer hospitalization costs if receiving curettage within 1-3 d after uterine artery embolization.

Objective To observe the correlation of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) appearances and blood stasis syndrome in breast cancer.Methods The clinical data of 100 patients with breast cancer confirmed by operation and pathology were retrospectively reviewed.70 cases without blood stasis syndrome,30 cases with blood stasis syndrome.All the cases underwent MRI using PHILIPS Achieva 1.5T magnetic resonance scanner before surgery.Results In no blood stasis group,76.67％ inhomogeneous enhancement,edge enhancement 43.33％,spiculation proportion 50.00％,which were significantly lower than those in the blood stasis group (88.57％,75.71％,83.33％).The mass ratio of the shape between the two groups had no significant difference (P ＞ 0.05).No blood stasis group and stagnation of blood group TIC curve was mainly type Ⅳ,type Ⅲ curve ratio of no blood stasis group (3.33％) was significantly lower than blood stasis group(12.86％) (P ＜0.01).In blood stasis group,Emax/1 and tumor size were higher than without blood stasis syndrome group.the percentage of V per minute outflow of blood stasis group was lower than without blood stasis syndrome group.Conclusion The clinician should make a preliminary evaluation of the prognosis before operation,in order to timely and reasonably choose the method of integrated traditional Chinese and Western medicine.
