ABSTRACT
OBJECTIVE：To study the effe cts of the water extract from Carpesium cernuum （AECC）on the proliferation ， metastasis and invasion of prostate cancer PC 3 cells. METHODS ：Cells were divided into control group and different concentration groups of AECC （5，10，20，40，80 μg/L），and then treated with relevant medicine or medium for different time （24，48，72 h）. The survival rates of cells were detected. Cells were divided into control group ，and AECC low ，medium and high concentration groups（20，40，80 μg/L）. After cultured for 24 h，Hoechst 33258 staining and flow cytometry were used to detect the apoptosis of cells. The number of cell metastasis and invasion were detected by Transwell assay. RT-qPCR and Western blot assay were applied to detect the mRNA and protein expression of β-catenin signaling pathway related migration and apoptosis proteins （β-catenin， MMP-7，c-Myc，caspase-3，Bcl-2 and Bax ）in AECC low and medium concentration groups. RESULTS ：With the increase of the concentration and culture time ，the survival rates of cells in AECC different concentration groups were significantly lower than control group （P＜0.05 or P＜0.01），and showed a decreasing trend. Compared with control group ，the early apoptosis rate （except the medium concentration group ）and the number of cell metastasis and invasion in AECC groups ，the mRNA and protein expression of MMP- 7，c-Myc（except for the low concentration group ）and Bcl- 2（except for mRNA of the low concentration group）in AECC low and medium concentration groups were decreased significantly （P＜0.05 or P＜0.01）. Late apoptosis rate of AECC groups ，the mRNA and protein expression of β-catenin，caspases-3（except for the low concentration group ），Bax（except for mRNA of the low concentration group ）in AECC low and medium concentration groups were increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：AECC could inhibit the proliferation ，metastasis and invasion of PC 3 cells；the mechanism of which may be associated with regulating the expression of β-catenin signaling pathway related migration and apoptotic factors.
ABSTRACT
Objective To investigate the nutritional status of elderly patients with diabetic foot ulcers and to explore its influencing factors and relationship.Methods Convenience sampling method was used to recruit 182 elderly patients with diabetic foot ulcers.The mini nutritional assessment (MNA) was adopted to assess nutritional status,and patients' clinical information,hemoglobin A1c,hemoglobin,serum albumin,C-reactive protein were also collected.Results The average score of MNA was 16.36±3.68 for 182 patients,and 121 patients suffered from malnutrition(66.48％),while 61 patients suffered from potential malnutrition(33.52％).The occurrence of malnutrition was positively correlated with age,course of diabetes,classification of foot ulcer,infection,C-reactive protein,hemoglobin A1c and food intake (P＜0.05);the incidence of malnutrition and C-reactive protein for patients with Wagner grade 3 and above were higher than those for patients with low Wagner grades,and hemoglobin A1c and hemoglobin were lower for patients with Wagner grade 3 and above(P＜0.05).Conclusion There was high incidence rate of malnutrition in elderly patients with diabetic foot ulcers,closely related to inflammatory state.Health care providers should provide targeted interventions in time,improve condition of malnutrition,and promote rehabilitation.
ABSTRACT
Objective To explore the relationship between the objective indexes and TCM syndromes of occupational hand arm vibration disease ,and to provide clinical data for the objectification of TCM syndrome differentiation. Methods 101 patients with occupational hand arm vibration disease were collected ,including 24 patients with Xingbi,39 with Tongbi and 38 with Zhuobi,according to the theory of traditional Chinese medicine syndrome differentiation ,the relationship was observed between different TCM Syndrome types and various of parameters,such as 5-and 10-minute rewarming rates in cold water rewarming test,terminal latency,amplitude, conduction velocity ,average time ,average amplitude of abductor pollicis brevis and abductor digiti minimi in electromyography. Results 5-and 10-minute rewarming rate in cold water rewarming test did not differ significantly among the three groups(P > 0.05). Amplitude of median nerve motor conduction differed significantly among the three groups of Xingbi,Tongbi and Zhuobi(χ2 = 6.14,P < 0.05),Further comparison between the groups was made in Xingbi and Tongbi(χ2=0.132,P=0.895),Xingbi and Zhuobi(χ2=2.277,P=0.023),Tongbi and Xingbi (χ2 = 2.172 ,P = 0.030). There were no significant differences among the three groups in latency and conduction velocity of the median nerve motor conduction and latency ,amplitude and conduction velocity of ulnar nerve motor conduction(P>0.05). The differences of conduction velocity and amplitude of median nerve and ulnar nerve sensory conduction,average time and average amplitude of abductor pollicis brevis and abductor muscle among the three groups had no statistical differences(P>0.05). Conclusions The distribution is different in the amplitude of median nerve motor conduction among the three groups of Xingbi,Tongbi and Zhuobi,further analysis shows that the difference is mainly reflected in the Xingbi group. We conclude that the median nerve axonal injury is lighter in Xingbi group than in the other two groups.

ABSTRACT
Objective To investigate the effects of sevoflurane preconditioning on autophagy after traumatic brain injury (TBI) in rats and the role of C-Jun N-terminal kinase (JNK) signaling pathway.Methods Sixty adult male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 4 groups (n =15 each) using a random number table:sham operation group (group S),group TBI,TBI + sevoflurane preconditioning group (group TBI + Sevo) and TBI + sevoflurane preconditioning + JNK inhibitor SP600125 group (group TBI + Sev + SP).TBI models were established using Feeney' s method.In TBI + Sev and TBI + Sev + SP groups,the rats inhaled 2.4％ sevoflurane for 30 min once a day for 4 concecutive days,and TBI was produced at 24 h after the end of sevoflurane preconditioning.In TBI + Sev + SP group,SP600125 (6 mg/kg) was injected intrapetitoneally at 30 min after TBI.Five rats were chosen at day 1,3,and 7 after TBI,and neurological deficit score (NDS) was measured.The rats were then sacrificed and brains were removed to measure brain water content,expression of LC3 lⅡ and Beclin-1 mRNA (using PCR),and expression of LC3 Ⅱ,Beclin-1,JNK and phosphorylated JNK (p-JNK) (by Western blot).Results Compared with group S,brain water content and NDS were significantly increased,and the expression of LC3 Ⅱ and Beclin-1 protein and mRNA,JNK,and p-JNK was up-regulated in the other three groups.Brain water content and NDS were significantly decreased,and the expression of LC3 Ⅱ and Beclin-1 protein and mRNA,JNK,and p-JNK was down-regulated in TBI + Sev and TBI + Sev + SP groups as compared with group TBI,and in TBI + Sev + SP group as compared with TBI + Sev group.Conclusion The mechanism by which sevoflurane preconditioning mitigates TBI is related to inhibiton of activation of JNK signaling pathway and decreased autophagy in rats.
ABSTRACT
Objective To study comprehensive nursing meassures for small area of diabetic foot ulcer. Methods A total of 58 patients with small area of diabetic foot ulcer in our department were divided into two groups.The comprehensive nursing group (CN group,30 cases) adopted comprehensive nursing and treatment as follows, surgical dcbridement, infrared radiation of wound surface,sprinkling of growth factors(bFGF and rhEGF),covered by hydrocolloid dressing(Algoplaque).The control group(28cases) received hydropathic compress with 0.5% povidone iodine or 5% furacillin solution.Wound heal-ing progreasion,average healing time and the positive rate of wound germiculture of the two groups were observed. Results The average healing time of the CN group was (29.6±9.4)d,which was shorter than that of the control group,( 39.2±13.5 )d, P < 0.05. Statistical difference existed in the positive rate of wound germiculture at the 7th day and the 14th day between the two groups (P < 0.05). Conclusions Routine medical treatment and general nursing measures plus surgical debridement,infrared radiation of wound sur-face,sprinkling of growth factors and hydrocolloid dressing possess facilitative healing effect for small area of diabetic foot ulcer.
ABSTRACT
Objective To examine the validity and reliability of the abbreviated mental test (AMT) among Chinese subjects. Methods Two groups of subjects participated in the study. One group consisted of 38 patients with neurological disorders and the other 30 normal subjects (control group). They were assessed twice with AMT and mini mental state examination (MMSE) within one week. Results AMT was significantly correlated with MMSE as far as the total score and item scores were concerned( r =0.706～0.833).There were moderate to high correlation in all the items of AMT between the two assessment tools(ICC=0.810～0.996). The AMT scores in the patient group were significantly lower than that in the control group (7.60?2.55 vs 9.64?0.81, P

ABSTRACT
Objective To study the validity and reliability of the simplified Chinese version of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA). MethodsThe English version of LOTCA was translated into the simplified Chinese first and then translated back to English to ensure its reliability in Chinese version.The we recruited two groups of volunteers to participate in the study. One group consisted of 36 patients with brain disorders (patient group), The other group consisted of 43 subjects without neurological disorders (control group). All the subjects were assessed with LOTCA and Mini-Mental State Examination (MMSE) within one session and on different days, respectively by two independent raters. Scores of LOTCA and MMSE were analyzed with Spearman correlation coefficient to test the validity of LOTCA. Intra-class coefficients (ICCs) were used to examine the intra-rater and inter-rater reliability of LOTCA. And Mann-Whitney test of non-parameters analysis was used to detect the sensitivity of LOTCA. ResultsThere was high correlation between the scores of LOTCA and that of MMSE ( r =0.9852- 0.9939 ). ICCs of LOTCA were 0.9923( P
ABSTRACT
@#Ninety- five cases(49 male .46 female)with first heamorrhagic cerebral apoplexy. fromOct.1 . 1992 to Dec.31 .1993. were analyzed.The Average age was58.9. Patients were divided intotwo groups. the self care and the non- self care. Ninteen variables which were supposed likely to be relatedto functional outcome were chosed from the admitted record of each patient and analyzed with mutltiple lo-gistic regression. Results showed that the major predictors of poor outcome are coma. incontinent and hemi-plegia at onset and abnormal blood urea nitrogen. pulmonary infection and bleeding amount more than 3 0ml at admitted.Cases older than 70 years.high blood presure longer than 20 years have a tendency of moredependence in functional abilities.Factors that do not predict outcome after heamorrhagic stroke are sex.days in the hospital,cormorbidities. as well as level of blood surgar and cholestral.EKG changes at admitted time.
