Objective To analysis the family management of patients with serious mental illness in Gansu prov-ince, and evaluate its effectiveness to lay the foundation for the better community-based rehabilitation management and treatment for the people with serious mental illness. Method According to Treatment-management specification of severe mental illness (2012) and specification of national basic public health services (2011), the information such as home ther-apy, medicine taken, and dangerous behavior happened were collected from patients who were confirmed as serious men-tal illness in January 2015 to April 2016 in Gansu province. Result Up to April 30th, 2016, totally 70538 serious mental illnesses were identified, and about 81.10%(57195) were under management. The rate of treatment of serious mental ill-ness was 69.9%(48009/68663) in Gansu province, and Bipolar affective disorder (76.0%) was the highest (P<0.001). The rate of taking medication in patients under family-management was 42.16%(24113/57195), and the rate of taking regular medication was 24.74%(14150/57195). The rate of taking medication in Paranoiac psychosis patients (51.98%) was the highest (P<0.001), and the rate of taking regular medication in Mental disorders caused by epilepsy (31.02%) was the highest (P<0.001). Conclusion The rate of family-management, treatment, taking medication and take regular medica-tion of serious mental illness in Gansu province are all below the national average level. A special training should be giv-en to medical professionals to strengthen their capacity to treat serious mental illness.

Objective To study the effects of quercetin(QUE) on proliferation of rat glioma C6 cell line in vitro.Methods The cells were divided into 5 treatment groups(10,25,50,75 and 100 ?mol?L~(-1) QUE),blank control and menstruum control group.The rat C6 cells were cultivated to 1?10~6?mL~(-1) in the RPMI 1640 medium,then added into 96 holes board with various doses of QUE by 3 holes per group,and MTT assay was used to observe the proliferation of the cells treated for 24,48 and 72 h.The change of cell cycle was also observed by flow cytometry(FCM) after the cells were treated with 50 and 100 ?mol?L~(-1) QUE for 48 h.The changes of the protein P53 and Bcl-2 of C6 cells treated with 50 ?mol?L~(-1) QUE for 48 h were detected by immunocytochemical methods.(Results With) the augmentation of QUE and the extension of the treated time,the C6 cell growth was inhibited,the A values decreased and the cell number in G_0/G_l phase was increased,the cell numbers in S and G_2/M phases were cut down,and the decreased expression of Bcl-2 protein and the increased expression of P53 protein were also observed after treatment with QUE.Conclusion Inhibitory effect of QUE on C6 cell line is proved to be dependent on the treated time of the drug and the dose of QUE,and the induced apoptosis of C6 cells is implemented by the means of up-regulation of P53 protein expression and down-regulation of Bcl-2 protein expression.

Objective To evaluate the correlation between osteophytes size and lower limb alignment in the knees of patients with Kaschin-Beck disease (KBD).Methods A total of 300 clinically diagnosed patients with KBD were X-rayed on knee-joints which ranged from the distal half of femur to proximal half of tibia.Meanwhile some related parameters in the X film with the anteroposterior position (including osteophytes length,femorotibial angle,femorotibial joint space ratio of inner side to outer side) were measured by DICOM 2.0,a software of medical graphic measuring,then followed by calculating the osteophyte spur index.The association between femorotibial angle,femorotibial joint space ratio and osteophytes spur index was evaluated by Pearson correlation test.Results The average of femorotibial angle of all the tested knee-joints was (165.97 ± 4.02)°,which positively correlated with both the osteophyte spur index of the medial femoral condyle [(6.54 ± 3.12)％,correlation coefficient (r) =0.524,P＜0.01] and the osteophyte spur index of medial tibil plateau [(7.14 ± 3.40)％,r =0.578,P ＜0.01].The femorotibial joint space ratio was 0.61 ± 0.13,which positively correlated with both the osteophyte spur index of medial femoral condyle (r =0.531,P ＜0.01) and that of the medial tibil plateau (r =0.563,P ＜0.01).Conclusions The results of this study indicate that there is a positive correlation between lower limb alignment and osteophyte size of both the medial femoral condyle and the medial tibial plateau.This finding may be evidenced by the fact that the changes of lower limb biomechanics may contribute to formation and development of osteophytes in the kneejoint.

Objective To explore the CT and MR imaging characteristics of intracranial melanomas. Methods CT and MRI characteristics in five patients admitted to our hospital from June 1993 to June 2000 and diagnosed as intracranial melanomas were retrospectively analyzed. Results There were two cases of primary melanoma and three cases of secondary melanoma. All the cases were examined by CT. The lesions presented as high density in 4 cases, and low density in only 1 case. Four cases were examined by MRI. Short T 1 and short T 2 signals were found in 3 cases, and slightly long T 1 and short T 2 signal was found in 1 case. Conclusion There are some special characteristics of melanomas on the MR imaging, which are helpful to ensure the diagnosis and distinguish the primary melanomas from secondary melanomas.

Objective To type Yersinia pestis isolated from Gansu Province,and to study the trend of diffreent strains in different administrative regions and different years.Methods Totally 193 strains were enrolled in this study,including 9 strains of Ganning Dauricus type,18 strains of Aerjin type,45 strains of Qilian type and 121 strains of Qingzang type.These strains were genotyped by clustered regularly interspaced short palindromic repeats (CRISPR),and genotypes were named according to international standard.Genotyping by CRISPR in different administrative regions and different years of Gansu Province was explored.Results Two clusters (Ca7 and Cb4),including four genotypes (genotypes 7,22,24 and 26) were classified by CRISPR.From the point of view of origin,genotype 24 was the main genotype in Akesai 36.36％ (16/44),Subei 36.17％ (17/47),Yumen 50.00％ (5/10) and Su'nan 38.67％ (29/75);the main genotype of Xiahe and Huining was genotype 26 (4/7);the main genotype of Shandan was genotype 22 (1/1).From the point of view of time,the main genotype of Yersiniapestis in Gansu Province during the years of 1960-1969,1970-1979 and 1980-1989 was genotype 26 [53.33％ (8/15),60.00％ (6/10) and 48.28％ (14/29)];the main genotype was genotype 22 [40.91％ (18/44)] during the years of 1990-1999;and the main genotype was genotype 24 [43.16％ (41/95)] during the years of 2000-2009.Conclusion Four genotypes of Yersiniapestis in Gansu Province are quite different in different administrative regions and different years.

Objective To study the correlation between patellar stability and keen clinical manifestation in adults with Kaschin-Beck disease (KBD).Methods Through a cross-sectional study in September 2016,one hundred and forty-three adult patients with KBD were asked to accept a digital radiographic X-ray (DR) which included positive and lateral slices of knee joint and axis slice of patellar.Meanwhile,every patient must undergo a Lysholm function evaluation for knee joint and morphological measurement on the DR film which included Insall index,lateral patellofemoral angle,sulcus angle,congruence angle,lateral migrating ratio of patella,and patellofemoral index.Then,the regression equation was built and the correlation analysis was made with multiple linear regression test.Results One hundred and forty-three patients' average scores of Insall index,lateral patellofemoral angle,sulcus angle,congruence angle,lateral migrating ratio of patella,patellofemoral index and Lysholm score were 1.10 ± 0.17,(14.49 ± 1.47)°,(138.08 ± 3.86)°,(11.55 ± 2.17)°,(1.34 ± 0.13)％,1.18 ±0.10,and (62.96 ± 6.11) scores.By multiple linear regression test,Insall index (X1),congruence angle (X4),lateral migrating ratio of patella (X5),and patellofemoral index (X6) were selected to enter into the equation;while,lateral patellofemoral angle and sulcus angle were rejected.The multiple linear regression equation was as follows:Y =17.529 + 15.232X5 + 0.950X4 + 15.957X6-4.224X1.The adjusted determination coefficient (R2) of the equation was 0.559.Those indexes which were selected to enter into the equation were ranked from big to small based on the impact on Lysholm as follow:congruence angle,lateral migrating ratio of patella,patellofemoral index,and Insall index.Among them,Lysholm score had a negative correlation with Insall index.Through variance analysis,F valve was 46.642,and P ＜ 0.05,which meant the fitted equation had statistical significance.Conclusion There is significant correlation between the patellar stability and knee Lysholm scoring in adult with KBD,which is reflected with the following parameters from big to small in turn:patellofemoral index,lateral migrating ratio of patella,congruence angle and Insall index.

Objective To observe the condition of Keshan disease (KSD) in Gansu Province in order to provide a scientific basis for prevention and control of the disease. Methods In 2011, according to “The national Keshan Disease Monitoring Program (trial edition)”, based on searching of KSD cases, 12 villages of 12 towns in 6 counties of Gansu Province, were selected as surveillance sites. All the residents in surveillance sites were clinically examined and given 12-lead ECG tracings; suspected cases were taken anterior chest X-rays in the distance of 2 meters, while staple food and life conditions of the residents were surveyed. Diagnosis of KSD was based on“Keshan Disease Diagnostic Criteria”(WS/T 210-2011). Results Among investigated 5 484 residents, the incidence of abnormal electrocardiogram was 15.41%. Of the 196 X-ray films, 61 cases had enlarged heart(in which 22 of mild, 21 of moderate and 18 of severe). Two hundred and forty-three cases of KSD were detected, the general detection rate was 4.43%, in which 31 cases of chronic, the detection rate was 0.56%; 212 cases of potential, the detection rate was 3.87%. In all cases, 47 cases were under the age of 30, including 46 cases of potential and 1 case of chronic. The major abnormal electrocardiogram change of KSD cases was ST-T changes[22.68%(71/313)], followed by complete right bundle branch block[16.29%(51/313)], low voltage[12.46%(39/313)], and left anterior fascicular block[6.71%(21/313)]. Per-capita annual income in surveillance site was 1 763 Yuan;and the major staple food was flour, accounted for 87%, and the staple food rice accounted for 5%. Conclusion The detection rate of KSD in Gansu Province is mainly to potential, and there is a cosiderable portion of patients under the age of 30;monitoring and investigation should also be strengthened in the younger age of KSD cases detected village.

Objective To investigate the occurrence of postoperative pain of hepatectomy and its possible related factors.Methods The clinical data of 555 cases undergoing hepatectomy was analyzed retrospectively,and the related influencing factors on postoperative pain of hepatectomy were analyzed by univariate analysis and multivariate logistic regression.Results Moderate postoperative pain was reported in 255 cases among 555 patients who underwent hepatic resection (with an incidence of 45.95％).Incision pain which was often sharp was most common,followed by postoperative complication caused pain.According to whether the postoperative pain occurred or not,all cases were divided into postoperative pain group (n =255) and non-postoperative pain group (n =300),univariate analysis showed that age (P ＜0.01),surgical history (P ＜ 0.01),surgical approach (P ＜ 0.01),incision length (P ＜ 0.01),xiphoid removal(P ＜ 0.01),the final outcome of incision (P ＜ 0.01),complications (P ＜ 0.01) were significantly different between the two groups.Logistic multiple regression analysis showed that the independent influencing factors of postoperative pain included surgical history (P =0.001),surgical approach (P =0.005),incision length (P =0.000),xiphoid process removal (P =0.001),complications (P =0.000).Conclusions The postoperative pain of hepatectomy has a high incidence.Surgical history,surgical approach,incision length,xiphoid process,removal and postoperative complications are the independent impact factors of postoperative pain.

Objective To grasp the epidemic features of Kaschin-Beck disease in different ecotypic areas in Gansu Province,in order to provide ecological basis for Kashin-Beck disease control.Methods Totally 37 counties with Kashin-Beck disease were divided into four ecological areas,villages with historical serious condition in township and townships with historical serious condition in county were investigated.Clinical examination and Xray of right hand of all 7-12-year-old children in the villages were carried out,while investigation of prevention and control measures was performed.Results Among 27 966 children from four ecological areas,the clinical detection rate was 0.05％ (14/27 966) and the X-ray positive rate was 1.26％ (353/27 966),metaphyseal rate was 1.25％ (350/27 966),bone-side positive rate was 0.01％ (3/27 966) and no case of epiphyseal and carpal were discovered.The clinical detection rate in children in the four ecological areas was not statistically significant (x2() =7.757,P ＞0.05),the Loess Plateau-gully region of Longdong [0.09％ (10/11 604)] ＞ the Anyon area of Qinling of Longnan [0.04％ (3/7 969)] ＞ Alpine grassland meadow area of Gannan [0.02％ (1/4 021)] ＞ the Loess Plateau-hills region of Longzhong [0 (0/4 372)].The detected rate of X-ray in four ecological areas was statistically significant (x2 =18.133,P ＜ 0.05),the Anyon area of Qinling of Longnan [1.49％ (119/7 969)] ＞ the Loess Plateau-gully region of Longdong [1.41％ (164/11 604)] ＞ the Loess Plateau-hills region of Longzhong [0.89％ (39/4 372)] ＞ Alpine grassland meadow area of Gannan [0.77％ (31/4 021)].Comprehensive prevention and control measures on Kaschin-Beck disease were different in different ecotypic areas.Relocation,long-distance education and selenium supplement measures had not been implemented in the four ecological areas.Conclusion The epidemic situation of Kaschin-Beck disease is different in different ecotypic areas in Gansu Province,which maybe related to ecological environment,but is under a state of control.

Objective To investigate the factors influencing the prevalence of echinococciasis in Gansu Province.Methods With the method of stratified random sampling,all the administrative villages in pastoral areas,half pastoral areas,agriculture and urban areas in the 72 counties in Gansu Province were selected;according to the layers of the population of the county population proportion calculated,the layer investigation numbers were determined,and a total of 16 administrative villages were selected in each county.In the 16 administrative villages,more than 200 people of permanent residents were surveyed in each village (shortage was made up from a nearby village),at least 3 200 people were investigated in a county.By using the combined method of inquiry and field observation,natural factors,such as drinking water,farming and animal husbandry production data were surveyed.All data were analyzed using SPSS 19.0 statistical software.Unauy linear and multiple linear regression analysis of influencing factors and the relationship between the prevalence were analyzed.Results Unary linear regression analysis showed that longitudes,latitudes,altitudes,average annual temperature,annual rainfalls,secondary industries,animal husbandry towns,drinking water sources,the number of epidemic towns,epidemic villages,per capita net incomes in animal husbandry regions,the total number of livestock and the number of sheep were factors influencing the prevalence of echinococciasis (F =4.705,P ＜0.05).Latitude,altitude,animal husbandry towns,the number of epidemic towns,epidemic villages,per capita net incomes in animal husbandry regions,the total number of livestock and the number of sheep and the prevalence of echinococciasis was positively correlated (r =0.282,0.285,0.387,0.508,0.540,0.317,0.475,0.594,all P ＜0.05);longitude,average annual temperature,annual rainfall,secondary industries,drinking water sources and the prevalence of echinococciasis was negatively correlated (r =-0.311,-0.244,-0.244,-0.389,-0.311,all P ＜0.05).Multiple linear regression analysis showed that differences of interactions of annual rainfalls,drinking water sources,epidemic villages,per capita net incomes of herdsmen,secondary industries and the total number of livestock between groups were statistically significant (t =-1.822,-3.920,3.013,1.715,-1.609,3.264,all P ＜0.05).Conclusion The factors influencing the prevalence of echinococciasis in Gansu Province are correlated with annual rainfalls,drinking water sources,epidemic villages,per capita net incomes of herdsmen,secondary industries and the total number of livestock.
