Objective To explore the construct validity of the Chinese version of Kinesthetic and Visual Imagery Questionnaire (KVIQ)-20 and KVIQ-10 in stroke patients and normal people. Methods From October, 2012, to March, 2014, 60 stroke patients and 60 nor-mal people with matched gender and age participated in this study. They were assessed with the Chinese version of KVIQ-20 and KVIQ-10. The construct validity was investigated with factor analysis. Results Two factors were extracted from KVIQ-20 for stroke patients after vari-max rotation, that accounted for 62.4%of the variance, as well as KVIQ-10 with 67.6%of the variance. Two factors were extracted from KVIQ-20 for normal people with 76.1%of the variance, as well as the KVIQ-10 with 69.6%of the variance. The factors could be named as visual imagery and kinesthetic imagery. Conclusion The Chinese version of KVIQ-20 and KVIQ-10 has good construct validity for assess-ing motor imagery from the dimensions of visual imagery and kinesthetic imagery, both in patients with stroke and normal people.

Objective: To investigate the actualities of service in Outpatient Pharmacy and Emergency Pharmacy. Methods: With queuing theory of operational research and data statistics, the specialities and varities of service in both Pharmacies were investigated before and after the application of computer network. Results: (1)The distribution of the patients number arriving the Pharmacies was unequal.(2) The time of service was extended after using network.(3)The average individual time of service in Emergency Pharmacy was 74 s, and 48 s in Outpatient Pharmacy. The reasons for the average individual time of service in Emergency Pharmacy more than that in Outpatient Pharmacy was related to the formulation of drugs in 2 pharmacies and the number of drugs on prescriptions. (4)The number of windows for service should be increased in Emergency Pharmacy after using network. Conclusion: Operational research and data statistics will provide the data assisting the manager in making decisions. [

Objective To investigate the efficacy of liver transplantation for the treatment of polycystic liver disease.Methods The clinical data of 8 patients with polycystic liver disease who received liver transplantation at the Third Affiliated Hospital from September 2003 to July 2009 were retrospectively analyzed.All patients underwent modified piggyback liver transplantation with vena cava plasty,and 1 of the patients received simultaneons liver-kidney transplantation.Data including acute rejections,complications,graft functions and survival time of patients were recorded.Results Operation was successfully performed on all patients.The mean operation time,anhepatic phase and operative blood loss were (7.5 +2.8)hours (range,4-11 hours),(42 + 14)minutes (range,25-70 minutes) and (2250 ± 1850)ml (range,2000-6500 ml),respectively.One patient received liver retransplantation at 45 days after primary liver transplantation because of hepatic artery stenosis.Two patients died during perioperative period.One patient died of pulmonary infection and multiple organ disfunction syndrome (MODS) at 39 days after operation,and the other one died of MODS at 59 days after operation.The median follow-up time was 60 months (range,37-93 months).Six patients survived for more than 3 years,4 patients survived for more than 5 years and 2 patients survived for more than 7 years.No acute rejection of gratis was observed at the end of the follow up.Conclusion Liver transplantation is safe and effective for the treatment of polycystic liver disease.

Objective To evaluate the efficacy and indications of salvage liver transplantation for patients with recurrent hepatecellular carcinoma(HCC)after liver resection.MethodsThe clinical data of 35 HCC patients who received salvage liver transplantation after liver resection at the Third Affiliated Hospital of Sun Yatsen University from October 2003 to March 2006 were retrospectively analyzed.All patients were divided into the salvage liver transplantation(SLT)group(n = 19)and extended SLT group(n = 16).Perioperative condition,postoperative complications and prognosis of the 2 groups were compared.The survival rate was analyzed and compared by the Kaplan-Meier method and Log-rank test,respectively.Results The anhepatic phase,ischaemic time,operation time,intraoperative blood loss,packed red blood cell transfusion,fresh frozen plasms transfusion,mobidity and retransplantation rate were(32 ± 9)minutes,(8.0 ± 2.1)hours,(7.6 ± 1.5)hours,2300 ml,8 U,23 U,6/19 and 2/19 in the SLT group,and(34 ± 7)minutes,(7.4 ± 2.3)hours,(7.4 ± 2.0)hours,2750 ml,12 U,20 U,4/16,1/16 in the extended SLT group,respectively,with no significant difference between the 2 groups(t=0.726,-0.804,-0.366,Z=-0.348,-0.549,-0.149,x2 =0.184,0.203,P＞0.05).The perioperative mortality,tumor recurrence rate were 0 and 2/19 in the SLT group,and 4/16 and 9/16 in the extended SLT group,with significant differences between the 2 groups(x2 = 5.363,8.426,P ＜ 0.05).The 1-,3-,5-year cumulative survival rates were 100%,84% and 84% in the SLT group,and 75%,33% and 33% in the extended SLT group.The 1-,3-,5-year tumor-free survival rates were 100%,89% and 89% in the SLT group,and 48%,29% and 19% in the extended SLT group.There were significant differences in the cumulative and tumor-free survival rates between the2 groups(x2 =11.58,19.31,P＜0.05).Conclusions The efficacy of SLT is satisfactory in the treatment of recurrent HCC.The optimal indication for SLT is Milan criteria.

In our screening for photosensitizers from natural resources, four alkaloids were isolated from Glycosmis pentaphylla by various chromatography techniques. Their structures were identified as glycoborinine (1), glybomine B (2), carbalexin A (3) and N-p-coumaroyltyramine (4) by spectral analysis. Their photoactivated antimicrobial activities were evaluated by thin-layer chromatography (TLC) agar overlay assay against Staphylococcus aureus and Bacillus subtilis. It was found that compounds 1 and 4 showed photo-activated antimicrobial activities. Meantime, photo-activated DNA binding activities of these compounds were also assessed by using a specially prepared 1.8 kb DNA fragment and restriction enzymes. Under UVA irradiation, compound 1 showed moderate inhibition on Nde I, Xba I, Nco I and Bcl I which have either 5'-TpA or 5'-ApT and trace or no inhibition on other restriction enzymes. It showed a similar inhibition pattern with the reference 8-methoxypsoralen. However, compounds 2-4 showed no inhibition against any of the restriction enzymes.

Objective To develop kinesthetic and visual imagery questionnaires applicable to Chinese stroke survivors and evaluate their test-retest reliability,inter-rater reliability and internal consistency.Methods The English version of a kinesthetic and visual imagery questionnaire (KVIQ) was translated into Chinese using wellaccepted questionnaire translation procedures.Thirty stroke survivors were each assessed twice using two versions of the translation (the KVIQ-20 and the KVIQ-10) by two experienced raters with an interval of 7 days between the tests.The test-retest reliability,inter-rater reliability and internal consistency of the visual imagery score (visual imagery subscale),the kinesthetic imagery score (kinesthetic imagery subscale) and the total scores for the KVIQ-20 and KVIQ-10 versions were analyzed.Results The test-retest coefficients,the inter-rater reliability correlation coefficients and Cronbach's alphas for the KVIQ-20 version ranged from 0.879 to 0.945,from 0.894 to 0.936 and from 0.867 to 0.919,respectively.The corresponding measurements for the KVIQ-10 vcrsion were 0.914 to 0.953,0.852 to 0.900 and 0.827 to 0.878.Conclusion Both the KVIQ-20 and KVIQ-10 Chinese instruments have shown good testretest and inter-rater reliability and good internal consistency in assessing stroke survivors.Either is an effective tool for assessing their motor imagery ability.

Objective To assess the effectiveness of prevention program on iodine deficiency disorders and iodine nutritional status of residents in Guangdong Province.Methods Probability proportionate to size sampling(PPS) was employed in surveillance of iodine deficiency disorders.Thirty counties(cities,districts) were selected in Guangdong Province.In each county(city,district) one township(street) was selected; in each township (street) one primary school was selected and in each primary school 40 children aged 8-10 were chosen to examine their thyroid and to collect salt samples at their home for determination of salt iodine.Out of the 40 children,12 children were chosen to collect urine samples for determination of urinary iodine.From the primary schools chosen,40 grade 5 students were selected for intelligence quotient(IQ) test.In the nearby of the primary schools,3 townships(towns,street) were selected and in each township(town,street) 5 pregnant and 5 lactating women were selected to collect their urine samples for determination of urinary iodine.Type-B ultrasonic was used in measuring the thyroid volume.The iodine content of urine samples was measured by the method of arsenic and cerium catalysis spectrophotometry.The iodine content of salt was determined quantitatively with the titration method.IQ was tested by Chinese combined Raven's test.According to geographical location and the implementation of iodized salt,the effects of iodized salt on iodine deficiency disorders were analyzed in the plains and the Pearl River Delta Coastal region with mild iodine deficiency(iodized salt implementation region,referred to as the plains and the PRD),historical iodine deficiency areas (iodized implementation region) and the eastern and the western coastal areas of Guangdong(areas with non-iodized salt problem,referred to as the eastern and the western Guangdong).Results A total of 1200 children aged 8 to 10 were examined by type-B ultrasonic test,and goiter rate was 3.5％ (42/1200).The differences of goiter rate between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant (x2 =6.6,P ＜ 0.05).The goiter rate (6.1％) in the eastern and the western Guangdong was significantly higher than that of the plains and the PRD and the historical iodine deficiency areas (3.3％,2.0％,x2 =5.6,7.1,all P ＜ 0.05).A total of 1200 salt samples were examined.The median and coefficient of variation of iodine in the salt were 31.0 mg/kg and 23.2％,respectively.Coverage of iodized salt was 97.5％(1170/1200) while 96.1％(1153/1200) of consumed iodized salt was qualified.The median urinary iodine of 1200 children aged 8-10 was 186.5 μg/L,and the differences of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong were statistically significant(x2 =5.9,P ＜ 0.05).The median urinary iodine of the eastern and the western Guangdong(162.4 μg/L) was significantly lower than that of the plains and the PRD(207.5 μg/L,x2 =8.7,P ＜ 0.01).The difference of median urinary iodine between the plains and the PRD,the historical iodine deficiency areas and the eastern and the western Guangdong was statistically significant(x2 =58.9,P＜ 0.01).The median urinary iodine of the eastern and the western Guangdong(109.6 μg/L) was significantly lower than that of the historical iodine deficiency areas and the plains and the PRD(152.9,155.2 μg/L,x2 =18.3,20.6,all P ＜ 0.05).The mean IQ of the 1208 grade 5 students was 102.8 ± 14.3.The IQ of the plains and the PRD(104.3 ± 13.9) and the historical iodine deficiency areas(102.7 ± 14.3) was significantly higher than that of the eastern and the western Guangdong(100.3 ± 14.7,t =3.8,2.1,P＜ 0.01 orP＜ 0.05).Conclusions The goal of iodine deficiency disorders elimination is achieved as scheduled in Guangdong Province.The health level of general population has been improved significantly.Iodine nutrition is in the appropriate range (100-199 μg/L) in general population but low in pregnant women.The selling of non-iodized salt in the eastern and the western Guangdong Province should be followed closely.
