ObjectiveTo explore the effect of motor imagery (MI) on knee function after unicompartmental knee arthroplasty (UKA). MethodsFrom January to September, 2022, 32 patients underwent UKA for the first time in Xuanwu Hospital were randomly divided into control group (n = 16) and experimental group (n = 16). All the patients accepted routine rehabilitation, and the experimental group accepted MI in addition, until four weeks after discharge. They were assessed with Oxford Knee Score (OKS), Visual Analogue Scale for pain (VAS), range of motion (ROM) of knee, and Timed Up and Go Test (TUGT) before and after treatment. ResultsAll the indexes improved after treatment (|t| > 2.517, P < 0.05), except ROM in the control group; and they improved more in the experimental group than in the control group (F > 7.999, P < 0.01), except the VAS score. ConclusionMI can further improve the knee function after UKA, but do less for pain.

ObjectiveTo study the conceptual framework and methodological system of the International Classification of Functioning, Disability and Health (ICF) in occupational therapy and its systematic implementation in clinical practice. MethodsBased on the ICF theory and the policy documents of the World Federation of Occupational Therapists, the conceptual framework of occupational therapy and the systematic implementation in clinical settings based on the ICF framework were analyzed. ResultsThis study constructed a conceptual framework and approach for occupational therapy based on ICF, and clarified the goals, principles, and implementation methods of integrated occupational therapy interventions in rehabilitation services. The goal of occupational therapy interventions was to improve the individual activity and participation through multidisciplinary and cross-cutting implementation of integrated occupational therapy programs to optimize functioning. Occupational therapy was based on the bio-psycho-social model, adhered to the principles of person-centeredness and functioning orientation, and implemented individualized intervention programs in different context. In clinical practice, it was recommended to follow ICF-based standardized process and systematically use World Health Organization Family International Classifications: functioning and unmet needs analysis using ICHI; functional classification, assessment and coding using ICF; disease classification, diagnosis and coding using ICD; intervention of occupational therapies using ICHI to build a systematic occupational therapy service system. ConclusionAn ICF-based occupational therapy concept and methodological system has been built, a comprehensive clinical occupational therapy implementation model has been established, the goal of activity and participation oriented occupational therapy interventions has been clarified, and the systematic, structured, standardized and refined level of occupational therapy has been enhanced.

Objective To study spatial attention processing characteristics in patients with unilateral spatial neglect (USN)by comparing the patients with right USN and behavioral findings of event-related potential (ERP)in normal subjects and the amplitude and latency of P1,N1 and P300. Methods Ten consecutive patients with USN (USN group)after right-hemisphere stroke admitted to the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University from April 2012 to April 2013 were enrolled retrospectively. Age-and sex-matched 10 normal subjects with the USN group were selected. ERP was used to document the electroencephalogram changes of two groups of subjects when performing visual Oddball pattern tasks. The response time and accuracy of target stimuli in both groups appearing on the left (left target)and right (right target)were analyzed and compared. The amplitude and latency of all ERP components (P1,N1,P300)on the left and right target stimuli were analyzed by repeated measurement of multivariate analysis of variance. The pathogenesis of USN after stroke was investigated. Results In the USN group,the accuracy of target stimuli on left side and right side was lower than that in the normal group (left target:17. 7 ± 7. 5% vs. 98. 5 ± 7. 5%,P＜0. 01;right target:88. 5 ± 2. 0% vs. 99. 0 ± 2. 0 %,P＝0. 002). There was no significant difference in P1 amplitude between the two groups (F ＝1. 104,P ＝0. 307). When the target stimulus appeared on the left side,the N1 amplitude on the right hemisphere of the USN group was lower than that of the normal group (-0. 3 ± 1. 1 μV vs. -5. 8 ± 1. 1 μV;P＝0. 001), when the target stimulus appeared on the right side,the N1 amplitude of USN group was lower than that of the normal group (-1. 8 ± 1. 0 μV vs. -6. 0 ± 1. 0 μV;F＝9. 799,P＝0. 006). The P300 amplitude of left target of the USN group was lower than that of the normal group (1. 0 ± 1. 1 μV vs. 7. 2 ± 1. 1 μV;P＝0. 001). Compared with the normal group,the latency of each wave of P1 (right hemisphere)(136. 7 ± 3. 8 ms vs. 122. 1 ± 3. 8 ms;P ＝0. 013),N1 (179. 7 ± 2. 0 ms vs. 172. 8 ± 2. 0 ms;F ＝5. 775,P ＝0. 027),and P300 (490 ± 12 ms vs. 402 ± 12 ms;F＝27. 310,P＜0. 01]in the USN group was prolonged. Conclusion During the spatial attention processing in patients with USN,regardless of the stimuli from the left and right,its information processing had been damaged to a certain degree.

Objective To observe and study the influence degree of strengthen training for family members for the treatment compliance and unhealthy lifestyle of patients with diabetes mellitus. Methods A total of 64 patients with diabetes mellitus from January 2015 to March 2016 were selected and divided into two groups by the method of random number table,32 patients in control group were taken care with routine nursing of diabetes mellitus,32 patients in observation group were taken care with strengthen training for family members,then the treatment compliance,related knowledge cognition of unhealthy lifestyle and unhealthy lifestyle situation of two groups before the intervention and at 4th, 8th and 12th week after the intervention were compared. Results The treatment compliance, related knowledge cognition of unhealthy lifestyle and unhealthy lifestyle situation of two groups before the intervention all had no obvious differences (all P>0.05). The treatment compliance at 4th, 8th and 12th week after intervention were (6.26 ± 0.32), (6.95 ± 0.36), (7.28 ± 0.40) scores in observation group, and (5.23 ± 0.29), (6.01 ± 0.30), (6.30 ± 0.33) scores in control group, and the differences were significant (t=8.253, 9.201, 10.257, all P<0.05). The related knowledge cognition of unhealthy lifestyle at 4th, 8th and 12th week after intervention were (80.78±5.90), (89.44±6.02), (93.43±6.20) scores in observation group, and (73.38± 5.73), (77.93±5.84), (82.20±6.01) scores in control group, and the differences were significant (t=11.258,12.563, 13.324, all P<0.05 ). The unhealthy lifestyle situation at 4th, 8th and 12th week after intervention were 75.00%(24/32), 90.63%(29/32), 96.88%(31/32) in observation group, and 59.38%(19/32), 68.75%(22/32),78.13%(25/32) in control group, and the differences were significant (χ2=7.251, 7.468, 9.169, all P<0.05). Conclusions The influence of strengthen training for family members for the treatment compliance and unhealthy lifestyle of patients with diabetes mellitus are more active, so the value of strengthen training for family members of patients with diabetes mellitus is higher.

Objective Toinvestigatetheeffectofrehabilitationrobothandontheupperlimbmotor functioninpatientswithstrokeandhemiplegia.Methods Theeffectsoftraditionalrehabilitation therapy or robot rehabilitation treatment of 15 stroke patients with hemiplegia were analyzed retrospectively. There were 4 females and 11 males. According to the group order,they were divided into either a robot rehabilitation group (n=8 )or a general rehabilitation group (n =7 ). The patients of the general rehabilitation group received general rehabilitation training at the Department of Rehabilitation Medicine for 4 weeks,3 times a week,and 30 min for each time. At the same time,they also conducted family rehabilitation training,5 times a week,once for 1 h;the patients of the robot rehabilitation group received the general rehabilitation training for the same length of time as the general rehabilitation group,and they also performed robot rehabilitation training,5 times a week,once for 1 h. The patients of both groups were evaluated with the modified Ashworth scale (MAS )scores,Fugl-Meyer motor assessment of the upper extremity(FMA-UE),andWolfmotorfunctiontest(WMFT)beforeandaftertreatment.Results Compared with before training,the MAS score of the robot rehabilitation group was decreased significantly after four weeks of training. The time in WMFT was shortened significantly and the function score was improved obviously. The scores of upper extremity,hand score,and total FMA score in FMA-UE were improved significantly,and there were significant differences (all P <0. 05 ),while there were no significant differences in various indicators in the general rehabilitation group (all P>0. 05). Comparing the effects after four weeks of rehabilitation in both groups,the robot rehabilitation group was superior to the general rehabilitationgroupforthehandscoreinFMA-UE(allP<0.05).Conclusion Therehabilitation robot hand effectively lowered the upper limb spasticity. It has significant effect for recovery motor function of hand;however,it did not have a significant effect for motor rehabilitation on wrist.

Objective To study the expression of microRNA-301 in pancreatic carcinoma andvalidate the significance of miR-301 in invasion and metastasis of pancreatic carcinoma.Methods miR-301 expression were detected by FQ-PCR in 5 pancreatic cancer eell lines(PANC-1,PaCa-2,AsPC-1,Hs766T.BxPC-3).Further immunohistochemistry in pancreatic cancer tissue microarrays was detected miR-301 expression,which contained 60 pancreatic cancer specimens along with 10 normal adjacent tissues and 10 normal pancreas tissues.After high expression of miR-301 in pancreatic carcinoma being confirmed.the clinical significance of high expression of miR-301 in invasion and metastasis of pancreatic carcinoma were studed.Pancreatic cancer cell lines(PANC-1.PaCa-2)were transfected by 100 nmoml/L miR-301 inhibitor(anti-miR-301)or negative eontrol(Anti-miR~(TM) Negative Control#1).COX-2 and MMP-2 protein expression in pancreatic cancer cell lines were detected by WB.and cell migration assays were performed using transwell technology.Results FQ-PCR resuhs indicated that miR-301 expression was higher in pancreatic cancer cell lines than normal pancreatic cells.The relative level of miR-301 in 5 pancreatic cancer cell lines(PANC-1,PaCa-2,AsPC-1,Hs-766T,BxPC-3)and normal pancreatic cell were 33.09± 4.21,30.76±3.18,47.57±3.56,20.20 ±1.21,76.75±13.51 and 1.00±0.08 respectively.The miR-301 level in all 5 pancreatic cancer cells were significantly higher than those of normal pancreatic cell(t=8.86,9.53,6.39,6.77,11.18,P<0.01).Immunohistochemistry results also showed miR-301 expression was higher in pancreatic carcinoma tissues than those in the cancer adjacent tissues and normal pancreatic tissues.The relative levels of miR-301 in pancreatic carcinoma tissues.normal adjacent tissues and normal pancreas tissues were 0.88±0.09,0.22±0.04 and 0.14±0.05 respectively.The miR-301 levels in pancreatic carcinoma tissues were significantly higher than those of normal adjacent tissues and normal pancreatic tissues(t=15.1,10.6,P<0.01).There was no significant difference between normal adjacent tissues and normal pancreas tissues(t=1.32,P=0.22).After miR-301 inhibitor was introduced into pancreatic cancer cells PANC-1 and PaCa-2.miR-301 levels were reduced while the protein levels of COX-2 and MMP-2.which were invasion and metastasis related factors,were down-regulated.The cell migration assay indicated the numbers of PANC-1 and PaCa-2 cells,which migrated to lower chamber.were 587±27 and 363±13 respectively after miR-301 inhibitor was applied.The numbers of migrated cells were 1091 4-15.737±44 when the netative control was applied.The cell invasion ability was decreased significantly in the inhibitor group compared with the negative group(t=7.89,7.56,P<0.01).Conclusions miR-301 is highly expressed in pancreatic cancer cell lines and pancreatic cancer tissues.Inhibition of miR-301 expression can effectively supress the invasion of pancreatic cancer cells.miR-301 may serve as a new biomarker for early detection of pancreatic cancer and molecular target for early treatment of pancreatic cancer.

BACKGROUND: In the past, the incidence rates of infectious diseases,natural epidemic diseases and endemic diseases in three gorges areas were always high. Because the flooded areas of Kaixian was enormous, the population of Kaixian was intensive density, the pollution may harm to the population health after the dam has been established.OBJECTIVE: To predict the influence of the Three-gorges dam on population health in Kaixian County of Chongqing and put forward to scientific evidence of preventive measures through analyzing the main health indicators and influence factors in Kaixian.DESIGN: Cross-sectional study.SETTING: Public Health College of Chongqing Medical University and Disease Controlled Center in Kaixian County of Chongqing.PARTICIPANTS: The survey was conducted in Kai County of Chongqing,from February to May 2004. All disease surveillance data of people in this county was investigated and other people lived in three-gorges area or around area were selected as the controls.METHODS: Collect and sort relevant indicators of social development,population health and public health system of Kaixian and related area to go deep into the representative townships to do some filed investigation,collect water samples of local drainage areas to carry out laboratory quantitative analysis; carry out comparative analysis based on the relevant materials; carry out comprehensive predicting and evaluation to the potential impact on population health of the three gorges engineering by combining the quantitative and qualitative analysis methods.general people in Kai county, Chongqing city and all over the nations durKai county, Chongqing city and all over the nations during 1999 and 2003;ty, Chongqing city and all over the nations during 1999 and 2001: Mortality rates of infants and under-five children were also higher than that average levels of whole country and Chongqing respectively; Multi-indicators showed that the general population health status of Kaixian was great bad,which stood a distinct gap among average levels of the whole country and Chongqing maintained about 250/100 000 or so, which was higher than the national level (190/10 000), however, the incidence rate of infectious diseases of Kaixian was rising year after year, even that of the recent two years has been reached up to more than 1.5 times higher than that of the whole of the water-based infectious diseases, especially the virus hepatitis, was severe. Another potential impact on population health of three-gorge dam is the emergence of natural epidemic diseases and insect-based infectious diseases. Malignant tumor such as hepatocarcinoma.CONCLUSION: We should strengthen current public health system, and cognition to the possible threat on disease epidemic and public health.With the construction of three-gorge dam, it is necessary to speed up establishment of effective measures to reduce predictable influence on population health.

90%.Then the purified sertoli cells were treated with the toxicants at different dose,i.e.DBP(0.1,1,10,100,500 ?g/ml),BaP(0.01,0.1,1,10,50 ?g/ml)and their combination DBP+BaP(0.1+0.01,1+0.1,10+1,100+10,500+50 ?g/ml).The viability of sertoli cells was determined by MTT method and the lactate concentration in the cultured medium was detected.Results As compared with DMSO control,the absorbance values in 100 ?g/ml DBP and DBP+BaP(100+10 ?g/ml)groups were significantly increased(P0.05).Lactate concentration in 100,500 ?g/ml DBP groups,50 ?g/ml BaP group and DBP+BaP(100+10,500+50 ?g/ml)groups were increased(P

Eight adult dogs distributed equally into control and therapy groups were fed on stock diet for 20 days and then irradiated whole-bodily with 60Co 4.65 Gy. After irradiation the control group was not given any therapeutic measure but fed on the diet as usual, while the therapy group was given with a larger amount of vitamins and high-caloric and high-protein diet, and sometimes force feeding was taken if the latter showed sign of anorexia. Whether higher values of nonprotein nitrogen in serum of two dogs in restored period and diarrhea happened in the therapy group were attribute to The treatments such as high-protein diet and force feeding were still unknown, the curing effects of nutrition and antibiotics were distinct as shown in that the body weight was easily maintained, and that the anemia and leucopenia wereless severe and recovered early. Moreover, within 30 days both the ther apy andcontrol groups one dog died respectively but survival time of the former was longer than the latter.

Weanlimg male rats fed on synthetic diet containing 1% succinylsulfa-thiazole and devoid of vitamin B12 and folic acid for 3-5 weeks, developed syndromes of the vitamins deficiency, i.e. poor food consumption, low growth rate, decrease in white cell count and marked increase in formimi-noglutamic acid excretion.Nevertheless, the others had an intake of vitamin B12 (0.02 ?g/day/-rat) and folic acid (0.5?g/day/rat) for a 36-day period, also showed signs of vitamins deficiency. But when given a daily dose of 0.1 ?g of vitamin B12 and 2.5 ug of folic acid, the rats had a good appetite and grew well, and excreted more formiminoglutamic acid than normal rats, when they were given a loading dose (0.05 g/rat) of histidine. Under the similar feed- ing condition, rat ingesting a daily dose of 0.3 ug of vitamin B12 and 7.5ug of folic acid, showed no obvious syndomes of the vitamins deficiency.After the rats were fed on the same diet and given with vitamin B12 (0.02 ug/day/rat) and folic acid (0.5ug/day/rat) for a 36-day period, the animals developed increased radiosensitivity. After total-body irradiation (700 rad), the food consumption, growth rate and survival rate in this group were lower than those in other groups ingesting individually 0.1 ug of vitamin B12 and 2.5 ug of folic acid or 0.3ug of vitamin B12 and 7.5 ug of folic acid daily.After irradiation, in the group of 0.02 ug of vitamin B12 and 0.5 ug of folic acid or 0.1 ug of vitamin B12 and 2.5 ug of folic acid in daily in-gestion there was a considerable increase in formiminoglutamic acid with a loading test of histidine(0.05 g/rat) than before. The results showed that the radiation intensified vitamins deficiency in rats.
