Objective To investigate the neuropsychological and functional neuroimaging features in patients with cerebellar infarction (CI).Methods We analyzed 59 CI patients (27 left CI,32 right CI) and 26 healthy control subjects who received standard and experimental cognitive testing and neuroimaging study.We compared the cognitive manifestations between the groups with Student' s t test.Results Patients with CI(left/right) achieved significantly lower scores in auditory verbal learning test (AVLT) of memory test (12.27 ± 1.37 vs 9.33 ± 1.90/10.25 ±2.20,t =6.46,4.26,P ＜0.05),Associative Learning of Clinical Memory Scale (22.77 ± 3.07 vs 18.67 ± 1.98/16.84 ± 3.55,t =5.74,6.69,P ＜ 0.05),symbol digit modalities test (SDMT) of visuospatial test(42.54 ±6.32 vs 20.85 ±9.57/34.84 ± 16.10,t =9.68,2.47,P ＜ 0.05),and errors responses (RE) of Wisconsin card sorting test for executive function (16.77 ± 2.64vs 52.22 ± 16.29/54.47 ± 16.27,t =11.15,12.89,P ＜ 0.05).Patients with left CI had significantly lower scores in correct responses percentage (RCP; 58.71 ± 10.93 vs 78.43 ± 5.26,t =-8.41,P ＜ 0.05)and significantly higher scores in the trials to compete first category (RF; 23.59 ± 9.79 vs 14.12 ± 3.75,t =4.68,P ＜ 0.05).Those finding suggests left CI would cause impairment on abstract conceptualization and concept formation; The patients with right CI had significantly lower scores in total memory quotient (86.69 ± 7.56 vs 112.02 ± 9.70,t =-11.17,P ＜ 0.05),higher scores in perseverative responses (RP ;44.59 ± 17.50 vs 8.23 ± 3.46,t =11.47,P ＜ 0.05) and nonperseverative responses errors percentage (nRPE; 44.00 ±20.67 vs 10.58 ± 2.35,t =9.07,P ＜ 0.05).It means right CI would cause serious deficits on memory,cognitive shift and attention.The fibers between cerebellum and frontal,parietal lobe were reduced in CI patients,compared with healthy control.Conclusions These results suggest that cerebellum participated in the formation of part of cognitive function by connection with cerebrum.After CI,that the fibers contacted with the prefrontal and parietal reduced is the possible mechanisms for cognitive impairment.

Objective To understand the current situation of the prevention and control of central venous catheter-related bloodstream infections ( CRBSI ) in ICU of three-level hospital , and explore the countermeasures .Methods The self-designed questionnaires were used in the study .The prevention and control and the quality management of ICUCRBSI at present in eight hospital were investigated ; and the cognition, the agree degree and the behavior of the related knowledge of the prevention and control of CRBSI in 252 nurses were also investigated .Results Six hospitals in eight hospitals had the standard operating procedure for the prevention and control of CRBSI , and two hospitals had the special check list for the maintenance of central venous catheter ( CVC) .The special prevention and control of CRBSI supported by the guideline of CDC in the USA was poorly carried out in the different hospital .The scores of the cognition , the agree degree and the behavior of the related knowledge of the prevention and control of CRBSI in 252 nurses were respectively (55.88 ±7.46), (20.21 ±1.48) and (72.59 ±6.83).Conclusions The three-level hospital in one city is lack of the standard operating procedure for the prevention and control of CRBSI , the check list for CVC catheter and maintenance .The medical staff should strengthen the training of the prevention and control of CRBSI , and increase the behavior compliance so as to decrease the incidence of CRBSI and improve the successful rate of rescue in the critically ill patients .

Background The mental health problems of employees in administrative organs and public institutions are highly valued.However,there is a lack of understanding regarding the mental health status of employees in provincial and municipal administrative organs and public institutions in Qinghai region.Objective To analyze the anxiety and depression of employees in provincial and municipal administrative organs and public institutions in Qinghai region,so as to provide references for promoting their mental health and intervening in psychological problems.Methods From October 23 to 28,2022,a total of 3 096 employees in provincial and municipal administrative organs and public institutions in Qinghai region were enrolled using stratified cluster sampling technique,and were assessed using Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS).Results A total of 1797(58.04％)employees in municipal and above administrative organs and public institutions in Qinghai region completed a valid questionnaire survey.Depressive symptoms were noted in 579(32.22％).SDS scores yielded statistical difference among the selected employees of different ethnicities,types of job positions and educational levels(F=9.074,101.488,4.477,P<0.01),and the severity of depressive symptoms also demonstrated statistical difference among the selected employees with different ethnicities,educational levels and types of job positions(H=49.196,17.028,160.848,P<0.01).Anxiety symptoms were detected in 711(39.57％)employees.SAS scores exhibited statistical difference among the employees with different genders,ages,ethnicities,educational levels,marital status and types of job positions(t=-4.571,F=6.648,3.950,5.243,12.008,22.253,P<0.01).Statistical differences were also illustrated in the severity of anxiety symptoms among the selected employees with different ages,genders,ethnicities,educational levels,marital status and types of job positions(H=24.361,-3.788,28.365,24.268,25.976,56.204,P<0.01).Conclusion About one-third of employees in municipal and above administrative organs and public institutions in Qinghai region may have symptoms of depression and anxiety.The depression symptoms are more severe among Tibetan people,those with low education levels and ordinary civil servants.The anxiety symptoms are more severe among employees aged 30 and below,those with low education levels,unmarried and those in technical positions.

Objective To explore the effects of military operation types on the mental health of Chinese veterans and the mediating role of psychological quality based on a dual-factor model of mental health.Methods Cross-sectional study design was adopted in this study.Self-designed demographic information questionnaire,patient health questionnaire depression module-9 item(PHQ-9),general anxiety disorder-7(GAD-7),satisfaction with life scale and psychological quality questionnaire were used to survey on 3 027 Chinese veterans.Results ① Compared to the one-factor model and the two-factor models with other indicators,the dual-factor model of mental health,with anxiety symptoms as a negative indicator and life satisfaction as a positive indicator,fitted better(Chi-square/df=8.927,GFI=0.974,AGFI=0.962,RMSEA=0.051,NNFI=0.985,IFI=0.988,CFI=0.988).②Taking the subjects who did not participate in war/non-war military operations as the reference,psychological quality showed significant relatively mediating effects between war and life satisfaction,and between war and anxiety symptoms(P＜0.05),while no such significances were observed in the corresponding ones for non-war military operations.③ War could decrease veterans'life satisfaction through full mediation of cognitive,adaptive and personality dimensions of psychological quality,and increase anxiety symptoms through partial mediation of the personality dimension of psychological quality.Conclusion The dual-factor model of mental health is applicable to Chinese veteran population,and psychological quality plays a mediating role between war and mental health.

Objective:To explore the impact of sleep quality on depression symptoms in perimenopausal women in urban communities.Methods:Using the convenient sampling method, a total of 2 300 perimenopausal women were selected as the research subjects from communities in four cities of Ya'an, Chengdu, Leshan and Deyang in Sichuan Province in March 2019. General Information Questionnaire, Patients Health Questionnaire-9 Items (PHQ-9) and Pittsburgh Sleep Quality Index (PSQI) were used to investigate the perimenopausal women. A total of 2 300 questionnaires were sent out in this study, and 2 300 were effectively received, with the effective recovery of 100% (2 300/2 300) .Results:The detection rate of depressive symptoms in perimenopausal women was 12.5% (288/2 300). The dominance analysis showed that sleep quality was the most important factor affecting depressive symptoms, followed by life events, marital status, chronic illness, per capita monthly household income and education level.Conclusions:Sleep quality is the most important factor affecting the depressive symptoms of perimenopausal women. It should be emphasized to improve the level of depression in perimenopausal women.

Objective To analyze the HIV-infection related behaviors among unmarried youths in rural areas of Liangshan prefecture from 2011 to 2013 and factors that influencing the HIV transmission in the population under research.Methods According to the HIV sentinel surveillance methods for data collection,EpiData 3.1 and SPSS 19.0 were used to handle data and both Chi-square test and logistic regression were used to explore the related factors.Results A total number of 5 871 qualified youths were involved in this study from 2011 to 2013 with the prevalence rate on HIV infection among those unmarried youths from the rural areas as 3.45％ (201/5 833).27.56％ (1 607/ 5 833) of them had been working outside their hometown area.31.72％ (1 850/5 833) of the unmarried youths had sexual experiences,with 41.46％ (767/1 850) of them had casual sex but the rate of consistent condom use was only 3.46％ (64/1 850).5.04％ (294/5 833) of the unmarried youths admitted of ever having used drugs,with 34.35％ (101/294) of them having the experiences of injecting,with 84.16％ (85/101) of them sharing needles.Rates on factors as:working outside the resident areas,ever having had casual sexual behaviors,drug use and injecting drug use were seen higher among HIV infections,with differences statistically significant (X2=88.72,104.43,4.20,154.39,55.94,P＜0.05).Results from the logistic regression showed that factors as:being male,Yi ethnicity,illiteracy,experience of working outside the resident area,never or casual condom use and needle-sharing drug use etc.would significantly increase the risk of HIV infection.Conclusions HIV infection among unmarried youths from rural areas in Liangshan prefecture called for attention because of the high rates of risk behaviors.Factors as:having had sexual experiences with low condom use,popular injecting drug use with needle sharing,being male,under Yi ethnicity,with lower education level and ever working outside the resident area etc.were under risks that related to HIV infection for unmarried youths in this area.

Objective To investigate the epidemiologic and behavioral characteristics of HIV among community population in Liangshan prefecture.Methods We collected social demographic,behavioral and serological information by means of the monitoring questionnaire and serological tests.Data was analyzed by using the chi-square test and logistic regression.Results From April to June of 2010 to 2015,14 092 cases of community population were selected as the study objects,with 267 cases diagnosed as HIV positive patients.The HIV positive rates were 3.24％,3.07％,1.17％,1.38％,1.42％ and 1.25％,respectively.We observed that when community population having the following characteristics as:living in Butuo country (OR=3.83),being males (OR=1.77),being Yi nationality (OR=4.40) being widowed (OR=28.57),with history of drug abuse (OR=3.71) or injecting drug use (PWID) (OR=4.92),or history of needle sharing among PWID (OR=8.53),were under higher risks for HIV infection.With histories as:having had secondary or above levels of schooling (OR=0.59),having protected sex with regular parmers (OR =0.21) and with non-regular partners (OR =0.46),they seemed to be somehow protected for getting HIV infection.Conclusion The positive HIV rates of HIV among community population in Dechang,Ningnan and Butuo varied from 0.10％ to 8.77％while the HIV transmission among general population remained challenging.

Objective: To analyze the situation of AIDS knowledge and discrimination among freshmen in Chengdu city, and to explore possible effects of AIDS knowledge on discrimination. Methods: A cluster random sampling was employed to investigate 1 053 college students from 11 universities in Chengdu about their HIV/AIDS knowledge and discrimination. The scores of AIDS knowledge and discrimination of students with different characteristics were analyzed, and the influence path of AIDS knowledge on AIDS discrimination were further analyzed based on different peer relationships. Results: The total scores of AIDS knowledge was negatively correlated to AIDS discrimination( r s =-0.13, P <0.01). After adjusting for confounding factors, the total score of AIDS knowledge was associated with the total score of AIDS discrimination( β =-0.12, P <0.01). AIDS knowledge played a role in AIDS discrimination in intimate, general and unfamiliar peer relationships, with standardized path coefficients of -0.20, -0.24 and -0.18 respectively( P <0.01). Conclusion AIDS knowledge are correlated with discrimination among freshmen under different peer relationships. More anti-AIDS discrimination courses should be added to AIDS education to reduce the students’ fear and stigma of HIV/AIDS patients and related risk groups.
