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.

A total of 121 subjects comprising 40 normal subjects,58 patients with overweight or obesity and 23 patients with Cushing's syndrome were recruited in the study.The modified radioimmunoassay (RIA) for salivary cortisol test was established'and its normal range was determined.Then the diagnostic value of the salivary cortisol for the initial diagnosis of Cushing's syndrome was evaluated and single midnight salivary cortisol test demonstrated a sensitivity of 100.0% and specificity of 91.4 %.Salivary cortisol test can be recommended as a first-line diagnostic parameter for Cushing's syndrome.

Objective To study the trend and changes regarding risk factors of pulmonary embolism among inpatients in the last 10 years from the First Clinical Hospital of Jilin University.Methods 303 cases of pulmonary embolism inpatients in our hospital from 2001-2010 were included and analyzed on related incidence,mortality and risk factors.Results Data showed that:(1)the incidence of pulmonary embolism increased from 0.09‰ to 1.12‰ while the mortality dropped from 73.3％ to 12.0％ ;(2)major risk factors would include thrombosis of deep veins,surgical operations,heart diseases,varicosity or phlebitis of lower extremities,trauma and fracture etc.,according to the order of incidence rates.Surgical operations had become the second major risk factor in the last 10 years.Conclusion The incidence of pulmonary embolism in our hospital showed a gradual drop while the mortality had a remarkable drop.Surgical operations had become one of the major risk factors of pulmonary embolism.

Objective To observe the effects of Bushen Huoxue acupuncture method on amygdaloid protein expression in SAMP8; To explore the potential target protein for acupuncture treatment of Alzheimer disease (AD). Methods Thirty six-month-old male SAMP8 mice were randomly divided into acupuncture group and control group, 15 mice in each group. Acupuncture group selected Baihui (GV20), Shenshu (BL23), Geshu (BL17) and Xuehai (SP10) to intervene. The control group was given the same time to catch and stimulate. After 8 weeks, the amygdala was extracted and the differential expression protein spots were identified by proteomic techniques. Results Compared with control group, acupuncture group eventually identified 9 differential expression protein spots, of which 6 up-regulated and 3 down-regulated. According to the relevant information provided in the protein database, the main function of differential expression proteins involved in the mitochondrial energy metabolism, oxidative stress, and production of Aβ. Conclusion Bushen Huoxue acupuncture method can regulate multiple protein expressions in amygdala, suggesting that it may be through improving mitochondrial energy metabolism, oxidative stress, reducing production of Aβ to realize the potential therapeutic effects on AD.

Objective: To observe the clinical effect of acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus electroacupuncture (EA) for treating peripheral facial paralysis and its influence on patients' facial nerve functions, facial disability index and clinical symptoms and signs. Methods: A total of 96 peripheral facial paralysis patients were allocated into an observation group, a medicine group and an EA group by simple randomization, with 32 cases in each group. Patients in the medicine group were treated with oral mecobalamine and prednisone acetate; patients in the EA group were treated with EA on the basis of the medicine treatment; while patients in the observation group were treated with acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA. After 4-week treatment, the clinical efficacy, the adverse events, and the scores of House-Brackmann (H-B) facial nerve function grading scale, visual analog scale (VAS), clinical symptoms and signs, and facial disability index (FDI) were compared. Results: After 4-week treatment, the total effective rate was 96.9％ in the observation group, higher than 68.7％ in the medicine group and 75.0％ in the EA group (both P<0.05). After 4-week treatment, the scores of H-B grading scale, VAS and clinical symptoms and signs in the three groups dropped significantly compared with those before treatment, and the scores in the observation group were lower than those in the medicine group and EA group (all P<0.05). After 4-week treatment, the facial disability index-physical function (FDIP) in the FDI in the three groups increased significantly, with a higher value in the observation group compared with that in the medicine group and EA group (both P<0.05). The facial disability index-social function (FDIS) in the FDI dropped significantly, with a lower score in the observation group compared with that in the medicine group and EA group (both P<0.05). However, the comparisons of the items above between the medicine group and the EA group showed no statistical significance (all P>0.05). The between-group comparison of the adverse event across the three groups showed no statistical significance (P>0.05). Conclusion: Acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA can decrease H-B grade, reduce pain severity and improve clinical symptoms and signs as well as the facial disability condition in peripheral facial paralysis patients. This method produced more significant efficacy compared with oral medicine and medicine plus EA.

Objective During June 2-8, 2009, 11 cases of the novel influenza A (H1N1)occurred in Sichuan Province, China. We investigated this outbreak to identify the source of infection,mode of transmission and risk factors for infection. Methods The primary case, a U.S. citizen,developed disease on June 2. From June 3 to 5, she joined Tour Group A for a trip to Jiuzhaigou. We telephoned passengers of the three flights on which the primary case had traveled in China, and members of Tour Group A. We asked whether they had any influenza-like symptoms during May 27 to June 12. Health authorities placed passengers whose seats were within three rows of the primary case on flights and members of Tour Group A on medical observation, and isolated individuals if they developed symptoms. We used real-time RT-PCR to test the throat swabs from symptomatic persons for the novel influenza virus and defined a confirmed case as one with influenza-like symptoms and laboratory confirmation. A retrospective cohort investigation to identify the risk factors for infection was conducted. We interviewed all members of Tour Group A about their detailed contact history with the primary case. Results During June 5 to 6, 9 (30%) of the primary case' s 30 fellow tour group members developed disease, compared with none of her 87 fellow passengers to Jiuzhaigou and 1 of her 87 fellow passengers on the returning trip (when several of the members of Tour Group A were symptomatic). 56% of the tourists who had talked with the primary case in close range ( ＜2 m) for ≥2 minutes developed disease, whereas none of the 14 other tour group members developed disease (RR= ∞; exact 95%CI: 2.0- ∞ ). Having conversed with the primary case for ≥ 10 minutes (vs. 2-9 minutes) increased the risk by almost five fold (RR=4.8, exact 95%CI: 1.3-180). Conversely, other kinds of contact, such as dining at the same table, receiving chewing gum from the primary case and sharing bus rides or planes with the primary case played no roles during this outbreak. Conclusion This novel influenza A (H1N1) outbreak was caused by an imported case, and transmitted mainly via droplet transmission when the primary case was talking with her fellow tourists during a tour. These findings highlight the importance of preventing droplet transmission during a pandemic.
