A pyelonephritis model of mouse is made by c. albicans infection. The determination of im-mune functions in model show that, both proliferation response of T cell to ConA and IL-2 activ-iting of spleenocytes of model animal to inductionwith ConA increased at 30 days after injected.The proliferation response of B cell to stimulation with LPS inhanced from 15 through 30 days,primary Ab response of model animal to SRBC stimulation inhanced between 15-30 days afterimmunization. DTH response to stimulation with c. albicans protein Ag raised since 15 days andup to peak at 30 days. Agglutination titer of serum raised up 15 days, and remained at higherlevel untill 30 days.

Objective To compare the clinical therapeutic effect of functional electrical stimulation (FES) and ankle-foot orthosis (AFO) in improving walking function in stroke patients.Methods Thirty-six stroke patients satisfying the enrolling criterion of the research were randomly divided into two groups:FES group and AFO group (n =18 in each).Both groups received the same routine rehabilitation therapy and medical treatment.Patients of FES group received FES of common peroneal nerve and tibialis anterior muscle of the affected limb,30 min per day,5 days per week,4 weeks in total,while the patients of AFO group received walking training with AFO wearing on,30 min per day,5 days per week,4 weeks in total.Walking function was assessed by 10-meter maximum walking speed,timed-up and go test (TUGT),functional ambulation category(FAC),the muscle tension of ankle flexor and Brunnstrom stage,which were carried out before treatment and four weeks after treatment.Results Before treatment,there was no significant difference between the two groups for the baseline of measurement(P ＞ 0.05).After 4 weeks of treatment,10MWT,TUGT,FAC scores and Brunnstrom stages in the two groups significantly increased (P ＜ 0.05).The 10MWT,FAC scores and Brunnstrom stage increased more significantly in FES group than those in AFO group (P ＜ 0.05).There was no significant differences with regard to TUGT and the muscle tension of ankle flexor between the two groups (P ＞ 0.05).Conclusions Both FES and AFO can accelerate the recovery of walking function in hemiplegia patients.FES can improve the walking ability in patients with stroke more significantly.

AIM: To evaluate the clinical effects of modified hydroxyapatite implant in scleral shell.
METHODS: Thirty - four cases were performed eye evisceration, autogenous sclera shell anterior and posterior petaloid shape with posterior sclera fenestration, hydroxyapatite artificial eyeballs were implanted at stage I, and conjunctival wound, orbital activity and other complications were observed after surgery.
RESULTS:The follow-up was 6 ~12mo. There was no patients with implant exposure, sclera dissolution, conjunctival wound dehiscence, conjunctival sac constriction noted. All the patients got good activity of artificial globe, and the active range of side motion of the HA was 10o ~15o. The artificial eyes looked symmetrical, and the eyes socket were full.
CONCLUSION: The modified hydroxyapatite implant in scleral shell can maintain the normal anatomy of the orbital tissue, and also can get full eyes socket and good activity, It was an easy and simple surgery which could obtain satisfactory clinical effect and less complications.

Objective To explore the recent and distant effects of early active training after the operation for lumber intervertebral disc herniation.Method 79 patients after the operation for mono segmental lumber intervertebral disc herniation had been divided into early active training group and routine control group randomly, and accepted training, regular re examination, and follow up of 1～ 6 years respedtively.Results The early active training group had better recent and distant objective effect, and more patients (97.6％ ) were satisfied with the operational effects.Conclusions The early active training after the operation for lumber intervertebral disc herniation is positive significant for operational effects.

Objective To observe the effect of CT-aided scalp surrounding needling on infraction dementia by retaining long time. Methods 53 infraction patients following dementia were randomly divided into treatment group (n=26) and control group (n=27). The control group was treated with CT-aided scalp surrounding needling for 30 minutes, while the treatment group was treated with CT-aided scalp surrounding needling for 3 hours. The course was 8 weeks. The therapeutic effect was assessed by Mini-Mental State Examination(MMSE), Hasegawa Dementia Scale(HDS-R) and Activities of Daily Living (ADL). Results The scores of ADL, MMSE, and HDS-R improved obviously after treatment in two groups (P<0.05), and the treatment group was better than the control group (P<0.05). Conclusion CT-aided scalp surrounding needling by retaining long time may facilitate to enhance the clinical effect on infarction dementia.

Objective To observe the effect of vein anastomosis by microvascular anastomotic device in head and neck reconstruction.Methods Sixteen cases needing free flaps were randomly selected in head and neck cancer patients with locally advanced lesion.Their veins were anastomosed by microvascular anastomotic device.Other 40 cases whose veins were anastomosed by manual anastomosis were selected as control during the same year.The statistical data of the time of veins anastomosis,thrombosis and the rate of flaps salvage were compared.Results The average time of venous anastomosis was 6.31 ± 0.87 minutes,which was lower than the manual anastomosis (19.20 ±4.62 minutes) significantly.There was no thrombosis,which was not significant different with the manual anastomosis.One case's venous blood flow was not smooth for the angled vein and the flap salvage operation was successful.Conclusion The time of venous anastomosis is shorten significantly by microvascular anastomotic device.The incidence of thrombosis is the same compared with venous anastomoses performed with sutures.The microvascular anastomotic device system allowed a time-efficient and safe venous anastomosis.

Objective To explore the effects of passive smoking on vascular endothelial function in office women.Methods Totally,94 healthy office women volunteers from urban(36 women)and townships or towns(58 women)were divided into three groups based on the extent of their daily exposure to passive smoking,group A exposed to one to eight cigarettes,group B exposed to nine to 15 cigarettes,and group C exposed to more than 15 cigarettes,respectively,with 20 healthy young women without exposure to passive smoking as controls.Internal diameter of the brachial artery Was measured by color Doppler ultrasound scanning for each of the participants and its changes were observed before and after congestive reaction of the brachial artery test and nitroglycerin test.Results Thirteen of 36 office women from urban and 38 of 58 from townships or towns exposed to passive smoking of more than eight cigarettes daily,with chi-square of 7.74,P=0.0054.The brachial artery in groups A,B and C dilated less than that in the controls did.The brachial artery in group C dilated less than that in the groups A and B did.Conclusion Passive smoking could damage vascular endothelial dilatation function in office women.
