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 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 analyze the clinical epidemiology of primary hepatocellular carcinoma (PHC) in the Xinjiang region. Methods Clinical data of the patients with PHC were collected at First Affiliated Hospital of Xinjiang Medical University from 5 577 cases from January 2002 to December 2014, their gender, race, age, household distribution, hepatitis virus-positive rate were analyzed retrospectively. Results Among the 5 577 eases, the men/women gender ratio was 3.45∶1;the proportion of Han, Uighur, Kazakh, and other ethnic groups (Hui, Mongolian, Manchu, Xibo) was 79.67%, 9.86%, 4.55%, 3.31%and 2.61%, respectively. The Constituent ratio difference between Uighur and Han was significant (P<0.05);4 232 patients had hepatitis B surface antigen (HBsAg) detection, and 3 833 patients had HCV antibody (HCV-Ab) detection. HBsAg was positive in 2 560 cases (60.49%), HCV-Ab was positive in 490 cases (12.78%). Hepatitis B virus detection positive rate in Uygur was 35.52%, in Kazak was 40.00%, which was lower than the Han's (65.68%, P<0.05). Urban and rural population had 3589 cases (64.35%) and 1988 cases (35.65%). Conclusion An increased risk for PHC was found in hepatitis virus-positive patients, the Xinjiang Uygur and Kazak people had significantly lower prevalence of HBV infection than the Han's. Appropriate measures should be taken for clinical diagnosis, treatment and prevention of PHC.

Objective To investigate the alteration of chaperonine hsp40 and its influence on delayed death of neurons in the CA1 region of hippocampus after transient cerebral ischemia. Method After transient global ischemia for 20 minutes, rat model was made. Following different lengths of reperfusion, all the 28 wistar rats were divided into sham-operation group,4 hour recovery group, 24 hour recovery group and 72 hour recovery group ( n = 7 rats in each group). Immunochemistry and laser scanning confocal microscopy were used to observe the distributional alteration of hsp40 in the neurons. Differential centrifuge and western blot assay were used to analyze the quantitative alteration of hsp40 and its redistribution in the neurons. Results Immunochemistry and laser scanning confocal microscopy showed the progressive reduction of hsp40 occurred at first in the cytosol, then in the nucleus until the death of all the neurons in the CA1 region died. Differential centrifuge and western blot assay showed the level of hsp40 decreased from 1.00 ± 0.21 to 0.23 ± 0.13 ( P < 0.01 ) 24 hours after reperfusion; the quantity of hsp40 in the protein aggregates increased from 1.00±0.18 to 8.61 ± 1.89 (P <0.01 =24 h after reperfusion.Conclusions The reduction of hsp40 in the neurons of hippocampus CA1 region is an important role in protein aggregates formation.
