ObjectiveTo learn the oral health cognitive behaviors and impact factors of the elderly people in Jining.MethodsThe number of 1026 elderly people were investigated by stratified cluster sampling method using the self-made questionnaire of oral heahh behaviors of the elderly people.Results ①In the number of 1026 elderly people,denture lost teeth accounted for 5.3％.There was no gendr differece in denture lost teeth( χ2=0.162,P ＞ 0.05 ) but age( t =- 9.089,P ＜ 0.01 ).②Brush teeth every day of the test total 86.3％,56.4％after dinner would gargle,0.6％ daily flossing,35.4％ used shaft brush.③The oral health behavior was related to the elderly pepole＇ gender,cultural level,economic income and participate in the oral health education activities based on the binary logistic.ConclusionThe old oral health behaviors are affected by various factors.To improve oral health awareness and promote oral health,the further strengthening community propaganda and education about oral health and control measures should be reinforced on the basis of the old oral health cognitive and behavioral status.

Objective To explore the characteristics of muscular power changes of knee joint and static balance in the elderly patients with knee osteoarthritis(KOA).Methods Isokinetic test and computerized static posturography were performed in 59 patients with KOA(KOA group) and 50 age-matched controlled subjects(conrtol group). The parameters were recorded.Results Peak torque, total work, average power and torque acceleration energy significantly decreased in KOA group compared with the control group at the low velocity of concentric pattern(P<0.05), while hamstring/quadriceps value increased statistically(P<0.05);The values of covered area, length of path, length/area statistically increased in KOA group compared with the control group only when eyes closed (P<0.01), and so did it in KOA group when eyes closed compared with eyes opened(P<0.05); There was significant relationship between length/area and hamstring/quadriceps value.Conclusion The ability of balance declined as knee muscular power decreased in the patients with KOA, especially the non-spontaneous decrease of extensor and flexor power of the knee joint.

Objective To discuss the diagnosis and management of metastatic adrenal carcinoma. Methods Forty-seven cases with metastatic tumor in the adrenal glands were analyzed retrospectively from December 1996 to April 2010. Lung was the most common primary tumor site (51.1 %, 24 cases), followed by the renal cell carcinoma (12.8%, 6 cases), liver cancer (10.6%,5 cases), breast cancer (8.5%, 4 cases), melanoma (4.2%, 2 cases), and other carcinoma (12.8%,6 cases). Most patients with metastatic adrenal carcinoma had no special clinic manifestation. Lesions of 36 cases were surgically removed and 11 cases gave up operation. Results The mean survival time were 33.8±4.5 months for 31 cases underwent adrenalectomy and 6.3±2.7 months for 6 cases without operation. Patients with surgically removed adrenal metastases had better survival than those without surgical resection. Conclusions Adrenal gland is a common site of metastatic carcinoma.Ultrasonographic and CT scans are important diagnosis methods for metastatic adrenal carcinoma. Operation is still effective and long-term survival may be achieved for those well selected patients, but surgical indication must be strictly monitored.

The necessity and superiority of the surgical operation on children with floating knee injury and the fracture union and complications were investigated. Twenty-eight children with floating knee injury were subjected to open reduction and internal fixation or external fixator. The patients were followed up for 18 months to 7 years. The curative effectiveness was scored by Karlstrom criteria. The results showed that no nonunion or deformity was found. The affected limb was 1.2 cm to 1.5 cm longer in 2 cases, 0.8 to 1.2 cm shorter in 3 cases than the contralateral. No severe dysfunction of knee joint occurred. The excellent-good rate was 92.8% and the curative rate 71.4% respectively. So for children whose age is older than 5 years, it's a good way to treat the fractures of femur and tibia with open reduction and internal fixation or external fixator. The method can be advantageous for the nursing care, early function recovery, shortening of the hospital stay and avoidance of severe complications.

AIM: To study the interactions of propofol and midazolam on the whole cell sodium channel currents in rat sympathetic ganglion neurons. METHODS: Whole cell patch clamp recordings were made from enzymatically isolated rat (7- 10 d ) superior cervical sympathetic ganglion neurons. Isobolographic analysis was applied to evaluate the potency of combinations of propofol and midazolam on Na + channel currents. RESULTS: Under V h= 80 mV and V t= 0 mV . Propofol and midazolam dose dependently blocked Na + currents with a mean drug concentration required to produce 50% current inhibition (IC 50 ): 33.12 ?mol?L -1 and 18.35 ?mol?L -1 ; clinically relevant concentrations of propofol and midazolam reduced Na + peak currents by 27.66 % (P

Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) on balance function of stroke patients in community. Methods 204 stroke patients in community were divided into control group (n=98) and observation group (n=106). The control group accepted routine rehabilitation and the observation group received PNF additionally. Fugl-Meyer Assessment of lower extremities (FMA), Berg Balance Scale (BBS) and static balance locator were used to evaluate the motor and balance function before and 3 months after treatment. Results The scores of FMA and BBS were higher after treatment than before (P<0.05) in both groups, and were higher in observation group than in control group (P<0.05). The length of path (L), covered area (A) and L/A were less in observation than in control group (P<0.05) both in the eye-open and eye-closed modes. Conclusion PNF can improve the lower extremities motor and balance function of stroke patients in community.

Objective To study the factors related with balance ability of the elder.Methods 37 persons above 60 years were assessed with the balanced function reflectoscope reflector,grouped according to their exercise practice.Results The length of locus and length/envelope area as eyes closed increased significantly compared with that as eyes opened in the less exercise group(P<0.05),while they were increased significantly compared with those in the more exercise group either when eyes closed or opened(P<0.05).Conclusion The exercise practice can improve the balances function of the old persons.

ObjectiveTo examine the effects of proprioceptive neuromuscular facilitation(PNF) techniques on lower limb motor function of strokes and its mechanism.MethodsWe used simple random sampling and cross-section survey design. PNF Contract Relax Agonist Contract(PNF-CRAC) techniques were applied to 44 stroke patients. Surface electromyography values(sEMG) was recorded from rectus femoris and hamstring of stroke patients with both low limbs. ResultsPNF-CRAC techniques not only caused the irradiation of muscles activities in the contralateral extremity during unilateral exercise, but also increased agonist EMG activities and the motor control of knee joint in strokes.ConclusionPNF-CRAC techniques can improve the knee stability and enhance the recovery of motor function in paretic lower limb.

Objective To investigate the effects of attention training, spatial and position sensation training and lower limb coordination training on balance and movement coordination of post-stroke patients. Methods 100 stroke patients were randomly divided into control group and observation group with 50 in each. The control group received routine rehabilitation, and the observation group received attention training, spatial and position sensation training and lower limb coordination training additionally. Both groups were assessed with Static Balance Test Equipment and Berg Balance Scale (BBS) before and 1 month after training. Results The balance function improved after training (P<0.05). Compared with the control group, the length of path (L), the covered area (A) and L/A in observation group significantly decreased (P<0.001), and the BBS score significantly increased (P<0.001) after training. Conclusion Strategic and targeted training such as attention training, spatial and position sensation training and coordination training, could improve static balance of post-stroke patients.
