Objective:To investigate the effects of comprehensive intervention on the quality of life of middle school students. Methods:Eight classes were extracted with striated cluster sampling method from the first grade of two key junior middle schools in city and countryside; four classes (two classes of the urban and rural) were selected randomly as the experimental group and another four classes (two classes of the urban and rural) as the control group. The experimental group received mental-social intervention for three years. No intervention for the control group. The effect was evaluated with the subjective quality of life of children, and a questionnaire on mental health of middle school students. Results:The scores of life quality, cognitive component and emotion component of experimental group were higher than that of control:(172.6?12.8/145.4?17.4,98.7?10.8/85.0?13.3,73.9?4.3/60.4?7.7; t=20.83, 13.20, 25.29 respectively;the average P

Objective: To explore the effect of comprehensive intervention to correct parental unhealthy rearing behavior on middle-school students. Methods: Eight freshman classes were randomly extracted from two key junior middle schools, four classes as the experimental groups, the other four as the control group. EMBU was applied to measure the difference before and after intervention of both groups. The comprehensive intervention was used, mainly the individual family mental health education and group family education. Results: After intervention, there were significant improvement in the parents' emotional warmth and understanding factors of experimental group(53.0?10.6/49.3?10.1, 55.7?10.9/50.4?10.5,t= 4.24 or 5.80,P

Objective To evaluate effects of pulmonary surfactant (PS) containing ketamine on respiratory failure induced with lung-lavage in rats Methods Twenty Wistar rats were anesthetized with intraperitoneal pentobarbital sodium and were ventilated with the peak inspiratory pressure(PIP) being 1 47 kPa and E:I at 1:1 following intubation through tracheotomy In all rats whole double lung lavage were performed with normal saline (37℃, 40 ml?kg -1 ) 8 10 times after PIP and PEEP were adjusted to 1 96 kPa and 0 49 kPa respectively The rats were randomly divided into A and B groups after PaO 2 decreased to less than 12 kPa In group A (n=10): PS (25mg, 0 5ml) was injected intratracheally to lungs; in group B (n=10): PS (25mg, 0 5ml) containing ketamine 2 5 mg was injected At 120th min after PS injection, PIP and PEEP were gradually adjusted to 1 47 kPa and 0 kpa (ZPEEP), respectively Results PaO 2 in both groups decreased significantly from 59 3 kPa to 10 3 kPa after lung lavage(P0 05 vs pre-lavage) All rats in group B and 4 of 10 rats in group A survived at the end of experiment Conclusions Intratracheal administration with PS containing ketamine not only reverses hypoxemia , but also maintains the respiratory function under low airway pressure without PEEP after respiratory failure induced with lung lavage,

Objective To detect food-specific IgE and IgG in patients with psoriasis.Methods Serum samples were collected from 102 patients with psoriasis,30 patients with chronic eczema,30 patients with chronic urticaria,and 30 healthy check-up examinees.Food-specific IgE and IgG were detected by commercial kits in these samples.Results No significant difference was observed in the detection rate of food-specific IgE or IgG among patients with psoriasis,patients with chronic eczema and patients with chronic urticaria (both P > 0.05).Meanwhile,the detection rate of food-specific IgE and IgG in healthy examinees were statistically different from those in the three groups of patients (all P < 0.05).Conclusions Food allergens seem to be implicated in the development of psoriasis.Moreover,the sources and kinds of food allergens in patients with psoriasis differ from those in patients with chronic eczema and patients with chronic urticaria,which deserves further research.

Objective To investigate the effects of different methods of volume therapy on the inflammatory response in patients undergoing liver cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients,aged 40-60 yr,with body mass index 20-25 kg/m2,undergoing liver cancer resection,were randomly divided into 2 groups ( n =20 each):routine fluid replacement group (group Ⅰ ) and goal-directed fluid replacement group (group Ⅱ ).The fluid replacement regime in group Ⅰ =compensatory volume expansion (CVE) + physiological requirements + cumulative loss + confinued loss + the third space losses.CVE was replaced with lactated Ringer's (LR) solution 5 mg/kg before anesthesia induction.The physiological requirements and cumulative loss were replaced with LR solution according to the principle of 4-2-1.The continued loss equal to the intraoperative blood loss was replaced with the equal volume of 6% hydroxyethyl s tarch ( HES 130/0.4).The 3rd space losses were replaced with LR solution 5 ml·kg-1 ·h-1.In group Ⅱ,CVE was replaced with LR sol6ution as in group Ⅰ.LR solution was infused after anesthesia induction at 5 ml·kg-1 ·h-1.6% HES was infused to maintain left ventricular ejection time (LVETc) between 350-400 ms.When 350 ms < LVETc < 400 ms and the amplitude of stroke volume ( SV ) increased by > 10%,6% HES was infused continuously until the amplitude of SV increased by ≤ 10%.Blood samples were taken before anesthesia induction and at the end of operation for measurement of serum TNF-α,IL-2,IL-4,IL-6 and IL-8 concentrations.The adverse cardiovascular reactions were recorded.Results Compared with group Ⅰ,the serum TNF-α,IL-6,IL-8 concentrations were significantly decreased,the serum IL-2 and IL-4 concentrations were significantly increase,and the incidence of hypotension and tachycardia was significantly decreased in group Ⅱ ( P < 0.05).No adverse cardiovascular reactions were found in both groups.Conclusion LVETc and SV-guided volume therapy can maintain the blood volume and inhibit the inflammatory response and is suitable for the patients undergoing liver cancer resection.

ObjectiveTo observe the efficacy and safety of inhaled tiotropium capsule on adult bronchial asthma.MethodsThirty-four adult asthma patients were randomized into two groups.We evaluated the addition of tiotropium bromide to an inhaled glucocorticoid in the treatment group( n =17 ),as compared with the addition of the LABA Formoterol in the control group ( n =17 ).Serial measurements of lung function,symptom control and quality of life were performed.ResultsAfter 8 weeks of treatment,peak expiratory flow (PEF) in the addition of tiotropium bromide group[ ( 359 ± 12 ) L/min vs.( 275 ± 5 ) L/min,P < 0.05 ] and the addition of the LABA Formoterol group [ ( 346 ± 11 ) L/min vs.( 275 ± 9 ) L/min,P < 0.05 ] were significantly higher than those before treatment.The forced expiratory volumes in one second ( FEV1 )were also significantly elevated in both groups [ Tiotropium bromide group:( 2.80 ± 0.28 ) L vs.( 2.30 ± 0.28 ) L,P < 0.05 ; LABA Formoterol group:( 2.69 ± 0.34 ) L vs.( 2.25 ± 0.34 ),P < 0.05 ] compared with pre-treatment.Average dose of emergent drug ( ventolin ) usage were decreased in both groups after treatment [ Tiotropium bromide group:(0.96 ± 0.34 ) puff/d vs.(4.11 ± 1.03 ) puff/d,t =3.05,P < 0.05 ; LABA Formoterol group:( 0.88 ± 0.44 )puff/day vs.( 4.43 ± 0.87 ) puff/day,t =3.23,P < 0.05 ].Meanwhile,significantly improved quality of life scores and alleviation of asthma symptom were found in both groups as compared with baseline ( P < 0.05).However,no significant differences in the above variables after treatment were found between two groups( P >0.05 ).ConclusionWhen added to an inhaled glucocorticoid,tiotropium improved symptoms and lung function in patients with inadequately controlled asthma.Its effects appeared to be equivalent to the addition of Formoterol.

Indirect fluorescent antibody test (IFAT) using frozen sections of Brugia malayi adult worms as antigen was employed in the diagnosis and epidemiological investigation of human filariasis. Sera were collected from 704 cases with bancroftian or malayan microfilaremia. the positive rate was 92.8-99.1%. Of 150 healthy people from non-endemic areas, only one showed a positive reaction (false positive rate 0.7%) (Table 1). This technique proved to be highly sensitive and specific for the diagnosis of filariasis and the antigen is easy to prepare. It might be used in sero-epidemiological investigation for the assessment of filariasis control.
