Objective To investigate the morphologic changes and hemodynamic parameters of the common carotid artery in obstructive sleep apnea hypopnea syndrome(OSAHS)in a porcine model using ultrasound and color Doppler.Methods A total of 12 pigs were randomly divided into model group and control group(n=6 for each).All pigs were fed under the same conditions with exception of th ose in the model group which were kept in a hypobaric chamber for experiments.The parameters of systolic velocity(S)and diastolic velocity(D),resistant index(RI)and S/D in Doppler as well as maximum IMT(intima-media thickness)with two-dimensional ultrasound were obtained in the carotid artery of all animals were determined,and the latter was confirmed by animal dissection when the symptoms of OSAHS appeared in the model group.Results The diameter of the lumen of the common carotid artery in model group(3.18?0.17)was smaller than that of control group(3.47?0.15,P

Chinese Journal of Orthopaedic Trauma 2004;0(10):-
Objective To investigate the operative treatment of displaced intra-articular fractures of the calcaneus using a small lateral incision approach.Methods Thirty-one patients with 32 intra-articular calcaneal fractures,were treated with open reduction and internal fixation through a small lateral incision approach from October 2004 to April 2006.The skin incision was made from the distal tip of the fibula to the base of the fourth metatarsal.According to Sanders classification,there were 21 typeⅡfractures and 11 typeⅢfractures.The first change of dressing was done on the second day after operation.The residual blood clots in the wounds were cleaned as much as possible when the drainage sheet was removed.The operated foot was bandaged with pressure dressing of cotton pad.Results After an average follow-up of 10.5 months(range,3 to 18 months),no soft tissue com- plications were found,and all had acceptable reduction.The preoperative X-ray film showed that B(?)hler angle was 6.84??9.36?,Gissane angle was 106.04??12.03?.The postoperative X-ray film demonstrated that B(?)hler angle was 32.06?+6.87?,Gissane angle was 115.81??9.48?,and the difference was statistically significant(P<0.01).According to the AOFAS evaluation system for Ankle-Hindfoot,two feet scored 60-70 points,nine feet 70-80 points,16 feet 80-90 points and five feet 90-100 points.Condusion The small lateral incision approach is a good option for management of calcaneus fractures,because it causes minimal soft tissue damage,provides excellent exposure,and leads to convenience for later removal of internal fixators and subtalar arthrodesis.

Objective To observe the therapeutic efficacy of low-frequency electrical stimulation (LFES) plus acupuncture in treating deglutition disorders after cerebral stroke. Method Seventy-six patients were randomized into two groups. The treatment group (38 cases) was intervened by LFES plus acupuncture;the control group (38 cases) was by LFES. Result The water drinking test scores were significantly changed after the treatment in both groups (P<0.05); after the intervention, there were significant differences in comparing the water drinking test score, improvement score, and therapeutic efficacy grading between the two groups (P<0.05). Conclusion LFES and acupuncture are both effective in treating deglutition disorders after cerebral stroke, and the combination of the two methods can enhance the clinical efficacy.

Objective To investigate the association between brain structure abnormalities and neuropsychology impairment in CAD patients.Methods Nineteen patients with CAD and 1 7 healthy adults were examed with MRI,and T1 WI,T2 WI,FLAIR,DWI and DKI image were performed,and then comparing the acquired MRI findings between two groups.Results Significant differences were observed for MK values in splenium and body of the corpus callosum,left cerebellar hemisphere and amygdala cerebelli.MK values of CAD group were lower than those of healthy group in these regions,and differences were statistically significant(P <0.05). There were significant correlation between MK values of the left amygdala cerebelli and MoCA scores in CAD group.Conclusion DKI could detect the changes of brain tissue microstructure in CAD patients early.The correlation between MK and neuropsychologi-cal function provides an important basis for early diagnosis and treatment.

Objective To observe the effect of constraint-induced movement therapy combined with motor imagery on unilateral spatial neglect (USN) in stroke patients. Methods Fifty stroke patients with USN were randomly divided into a treatment group ( n = 27 ) and a control group ( n = 23 ). Both groups received routine physical therapy training, including with the Bobath technique and low frequency electrotherapy, while the treatment group received constraint-induced movement therapy and motor imagery in addition. All the patients were assessed with 4 scales of the regular USN assessment ( cancellation tests, line bisection tests, clock drawing tests,copying drawing tests) and with the Barthel index (BI) before and after 8 weeks of treatment. Results After 8 weeks of treatment, both groups' average USN assessments and Barthel indices improved significantly. Furthermore, both the USN results and the Barthel index scores in the treatment group were, on average, significantly better than those in the control group. Conclusion For USN stroke patients, constraint-induced movement therapy combined with motor imagery improves the symptoms of USN and ADL ability significantly better than routine physical therapy treatment alone.

Objective To observe the influences of stemona alkaloids on esterase isozymes activities and glycogen content of Oncomelania hupensis in order to explore the molluscicidal mechanism of stemona alkaloids.Methods O.hupensis snails were immersed in the liquid of stemona alkaloids at the concentration of 6.5 mg/L(72 h LC50),the surviving ones were picked out and sampled after being immersed for 12,24,48,72,96 h,then PAGE and anthrone colorimetry methods were used to observe the changes of liver esterase isozymes activities and tissue glycogen content of O.hupensis during the immersion period.A group of snails immersed in de-chlorinous water served as control.Results Esterase isozymes activities firstly increased,and then decreased until almost lost completely during the 96 h immersion period.Meanwhile,glycogen content gradually decreased as the immersion time extended.After being immersed for 96 h,glycogen content decreased by 72.00% compared with the control group.Conclusion Stemona alkaloids could inhibit the viability of O.hupensis by causing decrease of esterase isozymes activities and glycogen content.

Objective To evaluate the clinical effects of partial fascicle from the ulnar nerve to biceps branch of musculocutaneous nerve to treat brachial plexus injury. Methods Six cases of brachial plexus injury were involved in this group.3 cases were upper trunk injury and 3 cases were accompanied partial lower trunk injury.A partial fascicle of ulnar nerve transfered to repair biceps branch underwent in all cases,phrenic nerve or accessory nerve were transfered to repair suprascapular nerve.The mean time from injury to surgery was 2.8 months.Patients were evaluated with regard to elbow flexion and should abduction ansle,grip strengthen,morbidity of ulnar nerve function lose. Results Five cases out of six got follow up.The mean period of follow-up was 18 months(range from 9-30 months).The average reinnervation time for the biceps muscle was 3.3 months. All the patients' recovery of elbow flexion Was M_3~+-M_5; and the shoulder adduction was 90°-180°;the grip strength was not downgraded. No notable impairment of the donor site nerve function was observed in 4 cases,just 1 case with a little more fascicle been harvested had partial ulnar nerve impairments. Conclusion The use of ulnar nerve partial fascicle to biceps branch combined with phrenic nerve or accessory nerve to suprascapular nerve to reconstruct upper roots avulsion of the brachial plexus is a valid and convenient procedure.It can obtain good functional restoration in elbow flexion and shoulder adduction in a resonable time.The cases with partial lower trunk injury of brachial plexus,the partial fascicle of ulnar nerve can still be used for repair the musculocutaneous nerve.
