ObjectiveTo explore relationship between psychological resilience and life events of Tibetan nursing students receiving free vocational nursing education.Method The questionnaire of Symptom Checklist 90(SCL-90)and ASLEC were used in the survey among 120 nursing students to investigate the psychological resilience and life events and SPSS 17.0 was used to look into the correlations between them.Results The scores on psychological resilience of Tibetan nursing students was higher than the norm (P<0.05).There were negative correlations between life events and psychological resilience(P<0.05).Their psychological resilience was positively related to personal relations and health conditions(P<0.05)but negatively to learning pressure,punishment and losses (P<0.05).Conclusion The school and hospital should make teaching measures to psychologically support them in daily life to strengthen the abilities to handle failure and adjust to the society.

Abstract: AIDS combined with Pneumocystis jirovecii pneumonia (PJP) and disseminated infections of Talaromyces marneffei and Cryptococcus neoformans are rare. This paper summarizes and analyzes the diagnosis and treatment of an AIDS patient with multiple fungal infections for reference. A 79-year-old male patient was admitted to the hospital with "stool habit change for more than 20 days". The white blood cell count was 4.57×109/L, the percentage of neutrophils was 81.8%, the absolute count of CD4+ lymphocytes was 6/μL, and the CD4/CD8 ratio was 0.17. HIV antibody positive was confirmed by CDC. The cerebrospinal fluid and alveolar lavage fluid were positive for Cryptococcus neoformans capsular antigen, and Pneumocystis jirovecii was found by the bronchoalveolar lavage fluid stained with hexamine silver. The cerebrospinal fluid culture was positive for Cryptococcus neoformans, and the blood culture was positive for Cryptococcus neoformans and Talaromyces marneffei. CT showed that bronchovascular bundles in both lungs were more thick, patchy and cable-like high-density shadows were seen in both lungs, and the edges were blurred. Nodular and cable-like high-density shadows were seen in the posterior apical segment of the left upper lobe, with clear margins. Infection of both lungs was considered, and secondary pulmonary tuberculosis occurred in the left upper lobe. After admission, the patient was treated with various anti-bacterial and fungal drugs due to recurrent fever, but the effect was not effective. The fever symptoms of the patient could not be significantly improved, and his condition continued to worsen, and he eventually died. The patient with AIDS complicated with bacterial and fungal infection, especially PJP infection in serious condifiton and has a poor prognosis for rapid development, so clinical attention should be paid to. 

Objective:To observe the changes of plasma oxytocin (OT), arginine vasopressin (AVP) and anxiety after exercise intervention in male opioids-dependent patients.Methods:Forty-five male opioids addicts who met the inclusion criteria and voluntarily participated in exercise rehabilitation were enrolled.According to stratified random sampling, all subjects were divided into exercise group ( n=22) and control group( n=23). Exercise group attended aerobic exercise combined with resistance training intervention, 5 times per week for 8 weeks.Aerobic exercise was mainly treadmill and elliptical, while resistance training was based on strength and endurance training.Subjects completed self-rating anxiety scale (SAS) and Chinese perceived stress perception scale (CPSS) before and after intervention, as well as physical fitness tests. Besides, plasma OT and AVP levels were detected.Independent sample t-test, paired sample t-test, and Chi-square test were conducted by using SPSS 20.0 software. Results:Before the intervention, there were no significant differences between the two groups in demography, drug history, SAS, CPSS, plasma OT and AVP(all P>0.05). The overall anxiety detection rate was 66.67%, the scores of SAS and CPSS were both higher than the Chinese norm, and the difference was significant(both P<0.01) . After the intervention, the levels of plasma AVP, the scores of SAS and CPSS in the exercise group (AVP(19.57±2.23)pg/ml, SAS(50.17±10.09), CPSS(36.59±6.36)) were significantly lower than those in the control group (AVP(22.53±2.56)pg/ml, SAS(57.12±12.00), CPSS(43.09±5.57), all P<0.05), and plasma OT((61.98±5.27) pg/ml) was significantly higher than that in the control group ((54.64±7.62) pg/ml)( P<0.01). Compared with baseline, maximal oxygen uptake(VO 2max), 1 min push-ups and sitting body flexion increased significantly in the exercise group (all P<0.05). Conclusion:Opioids drug addicts were prone to excessive stress and anxiety and other negative emotions in the process of drug withdrawal. Eight-week aerobic combined with resistance exercise changed the plasma OT and AVP levels of opioids addicts, effectively alleviated the perceived stress, improved the anxiety state and their health related fitness level.

Objective To explore the protective effects of proanthocyanidins pretreatment on intestinal function after cerebral ischemia-reperfusion injury. Methods 24 Sprague-Dawley rats were randomly divided into sham group (group A, n=8), ischemia-reperfusion group (group B, n=8) and proanthocyanidins pretreatment group (group C, n=8). The model of cerebral ischemia-reperfusion injury in rats was established according to Longa's method. Group C was intraperitoneally injected with proanthocyanidins 10 mg/(kg ⋅ d), group A and group B were injected with normal saline for 5 consecutive days. 1 and 3 days after cerebral ischemia-reperfusion, ileum myoelectric slow wave and smooth muscle contractility, the activity of superoxide dismutase (SOD) and content of malondialdehyde (MDA) were measured, the content of the serum TNF-α was tested with ELISA kit, ileum tissues were tested with hematoxylin eosin (HE) staining and used for measuring the moisture content. Results Compared with group B 1 and 3 days after cerebral ischemia-reperfusion, the intestinal mucosa injury relieved, the intestinal mucosa score decreased (P<0.05) and the number of infiltrated inflammatory cell decreased in group C; the frequency of slow wave and contraction trended to increase (P>0.05), and the amplitude increased (P<0.05) in group C; the serum SOD activity increased (P<0.05), and the content of MDA and TNF-α decreased (P<0.01) in group C; the intestinal moisture content reduced (P<0.01) in group C. Conclusion Proanthocyanidins pretreatment can protect intestinal function from injury after cerebral ischemia-reperfusion.

OBJECTIVETo study the life events which are correlated with adolescent's emotion and behavior problems, and to provide evidence for clinicians and school staff to develop intervention for those problems.

METHODSYouth's Self Report (YSR) and Adolescent Self-Rating Life Events Check List (ASLEC) were used to assess adolescent's emotional and behavioral problems and life events by 'spot' study. The referred group consisted of 585 patients from 11 to 18 years old in a Mental Health Centre of West China Hospital of Sichuan University from July in 2002 to March in 2004. Level of IQ was above 5th grade of primary school among the study subjects who were willing to fill in the YSR and ASLEC. The non-referred group was selected in a 1280 students cluster-sample from the schools of Chengdu city, whose sex, age and father's career were matched with the referred group. Variance inflation factor (VIF) was used to verify that there was no collinearity to each other in the 6 factors of ASLEC: interpersonal relationship, learning pressure, being punished, losing good adaptation and other. Linear stepwise regression was adopted.

RESULTSThe YSR scores in referred group were higher than those in non-referred group, and the referred group had more emotional and behavioral problems than the non-referred one. Partial correlations ranged from 0.124 to 0.418 in referred group, and from 0.104 to 0.388 in non-referred group. Unsatisfied interpersonal relationship, heavy learning pressure, having been punished and poor adaptation were likely to increase the risk of youth's emotional and behavioral problems.

CONCLUSIONMore attention should be paid to help adolescents in the following areas: solving intrapersonal affairs, relieving pressure from learning, avoiding punishment, and improving ability to fit themselves to their surroundings.

OBJECTIVETo study the mental health problems in the adolescents aged 11-18 years in Chengdu, China.

METHODSYouth Self-Report (YSR) and the General Information Questionnaire were administered to 1802 students who were randomly selected from schools in Chengdu City.

RESULTSThe overall rate of mental problems was 15.1% in the adolescents, 15.2% in boys and 14.9% in girls if 90th percentile of total scores and/or 98th percentile of syndromes scores were assigned as the cutpoint of norms. The overall rate of mental problems was 27.2% in the adolescents, 27.6% in boys and 26.8% in girls if 75th percentile of total scores and/or 98th percentile of syndromes scores were assigned as the cutpoint of norms. The rates of mental problems were not significantly different between boys and girls (chi-squared = 0.042, P = 0.838; chi-squared = 0.126, P = 0.723). Mental problems tended to be increasing with age (P = 0.000). There were 29 items that the percentiles were higher than 50% but 5 items were under 10% in all the 101 items of YSR. 3.1% of the adolescents often had suicidal intention, and 6.1% of the adolescents often thought of becoming opposite sex identity.

CONCLUSIONThe rates of mental problems in adolescents aged 11-18 years in Chengdu, Chana were 27.2% or 15.1% respectively,if 75th or 90th percentile of the total scores were assigned as the cutpoint of total scores. The mental problems in the adolescents tended to be increasing along with age.

OBJECTIVETo explore the neuropsychological characteristics of children with attention deficit hyperactivity disorder (ADHD).

METHODSNeuropsychological tests, including visual working memory, Stroop test, digits inverse reciting, vocabulary fluency, Wisconsin card sort test (WCST), and Temporal discounting were used to evaluate the capacity of response inhibition, phonological working memory, visual working memory executive function and delayed satisfying capacity of subjects.

RESULTS1. The ADHD children spent longer time [ADHD-I (84(20), ADHD-C: 98 (31), normal: 70 (28)] to accomplish color naming and made more errors [ADHD-I: 3 (3), ADHD-C: 6 (19), normal: 2 (5)] than the normal control when the color was inconsistent with the word meaning in Stroop test (P < 0.01). 2. The scores of digits reciting [ADHD-I: 3 (3), ADHD-C: 3 (4), normal 4 (4)] inverse was lower in ADHD than in normal control (P < 0.01). 3. The representation of ADHD was poorer than normal control in visual working memory [ADHD-I: 21 (3), ADHD-C: 20 (5), Normal: 20 (3)], and in delayed visual memory [ADHD-I: 19 (5), ADHD-C: 19 (5), Normal: 20 (5)] (P < 0.01). 4. The scores of vocabulary fluency [ADHD-I: 1 (1), ADHD-C: 2 (1), normal: 0 (0)] was lower in ADHD than in normal control (P < 0.01). 5. In WCST, the ADHD children made more errors [ADHD-I :15 (17), ADHD-C: 15 (15), normal: 13 (13)] and less classification [ADHD-I: 5 (4), ADHD-C: 5 (4), normal: 5 (3)] than normal control (P < 0.01). 6. In Temporal discounting, the ADHD children showed significantly more impairments than normal control did (P < 0.01). 7. There was significant difference between the two subtype groups on some tests (P < 0.01).

CONCLUSIONSObvious cognitive impairments were found in children with ADHD, involving poor response inhibition, impaired working memory, dysfunction of planning and set-shifting, and there was no significant difference between the two subtype groups.

The purpose of this study was to investigate whether pretransplant infusion of reactive natural killer cells (NK cells) from donor or recipient can reduce graft-versus-host disease (GVHD) and enhance engraftment in bone marrow transplantation (BMT). Recipient BALB/c mice were divided into 4 groups after received 6.5 Gy total-body irradiation (TBI): control group 1 was treated with nothing, control group 2 received BMT alone, experiment group 1 received BMT and autoreactive NK cells, experiment group 2 received BMT and alloreactive NK cells. Life span, clinical and pathologic changes of GVHD and chimerism rate of each group were evaluated. The results showed that all mice were survival in control group 1. The life span was shorter in experiment group 1 than that in control group 2 (P < 0.05) and longer in experiment group 2 than that in control group 2 (P < 0.01). GVHD was higher in score of experiment group 1 than in control group 2 (P < 0.05) but lower in experiment group 2 than that in control group 2 (P < 0.01). The donor chimerism rate in both two experiment groups were higher than that in control group 2 (P < 0.05), however, the donor chimerism rate was higher in experiment group 2 than that in experiment group 1 (P < 0.01). It is concluded that pretransplant infusion of alloreactive donor NK cells can prolong life span, reduce the degree of GVHD and enhance engraftment. But autoreactive recipient NK cells can shorten life span, aggravate the degree of GVHD and also enhance engraftment, which is weaker than that using alloreactive donor NK cells.
