Objective:To investigate the environmental factors a nd individual personalities of anorectic children in order to improve their nu rsing care.Methods:Forty-six children with anorexia caused by emotional disorders and 50 healthy children were tested by a societa l-psychological factor questionnaire and the Eysenck Personality Questionnaire (Junior) to observe their external environmental factors and individual persona lities,respectively.Results:Encidence of pressures from school work,forced eatin g by parents and family discord emerged more frequently in the anorectic group than in the co ntrol group.Scores in the anorectic group were significantly lower in the scale E level and markedly higher in the scale N level than those of the control group (P<0.01).There was no significant difference between the two groups in the P and L scales .Conclusion:The three factors mentioned above were most closely related to onset of disease, among the factors we observed.Both an intro verted personality and unstable emotions are key,characteristics that can induc e anorexia when affected by these factors.Comprehensive nursing care,mainly cons isting of psychiatric-behavioral correction,is proposed to obviate the inducing factors and rectify emotional disorders to promote recovery from anorexia.

Objective To investigate the clinical efficacy of photodynamic therapy using low concentration of photosensitizer, short incubation time and red light source in the treatment of ache. Methods Thirty patients with facial ache were equally randomized into two groups, one group applying 5% 5-aminolevulinic acid (ALA) to the facial lesions on the right side and placebo agent on the left side as control, the other applying the same concentration of ALA to the facial lesions on the left side and placebo agent on the right side as control. The whole face of every subject was irradiated with red light once a week for 4 sessions. The lesions were counted by a dermatologist, sebum production was measured by a sebum meter (SHP88) and pigmentation index by Mexameter MX 18, at the baseline and on week 2, 4, 8 after the last treatment. Adverse effects were also recorded at each visit. Results Two weeks after the last treatment, a sixty percent or more clinical improvement was achieved in the ALA-treated side of 25.9% patients, but no patients experienced sixty or more percent clinical improvement in control side, and the efficacy of ALA was superior to that of the placebo (P<0.05). A significant reduction was noticed in the count of every kind of lesions, including comedo, papules, pustules, cysts/nodules, as well as the total count of these lesions compared with the baseline (all P<0.05); meanwhile, only the pustule count and total count of lesions were decreased in the control side (both P<0.05). Conclusions Both ALA (5%)-PDT and red light-irradiation alone can reduce the number of acne lesions, but the former is more effective than the latter with few side reactions.

Objective To evaluate the reliability of gas sampling from the distal end of the tracheal tube for partial pressure of end-tidal CO2 (PETCO2) monitoring in neonates.Methods A total of 50 fullterm neonates,scheduled for elective abdominal surgery under general anesthesia,aged 1-28 days,weighing 2.55-4.00 kg,of ASA physical status Ⅰ or Ⅱ,were randomly divided into 2 groups (n =25 each) using a random number table:gas samples collected from proximal end of tracheal tube group (group P) and gas samples collected from distal end of tracheal tube group (group D).Epidural catheters of 1 mm in external diameter were used.One end of the catheter was connected to a tube for carbon dioxide sampling,and the other end was inserted into the endotracheal tube and advanced toward the distal hole of the tube.At 15 min of mechanical ventilation,blood samples were collected from the radial artery for record of PETCO2 and for blood gas analysis.Consistency test was performed between PETCO2 and partial pressure of arterial CO2 (PaCO2).Results PET CO2 was significantly lower than PaCO2 in the two groups.There was no significant difference in PaCO2between the two groups.PETCO2 was significantly higher in group D than in group P.Kappa was significantly higher in group D than in group P.Conclusion Gas sampling from the distal end of the tracheal tube is more reliable than gas sampling from the proximal end in monitoring PETCO2 in the neonates.

Objective To observe the efficacy, benefits and shortcomings of pressurized air therapy for neo- natal hypoxic ischemic encephalopathy (HIE). Methods One hundred and nine neonates with HIE were treated with hyperbaric oxygen (HBO) with a continuing oxygen supplement from an improved oxygen mask plus a 2.5-1itre breathing sacculus proprius in a large air-pressurized oxygen chamber. Among them there were 70 cases treated with 3-6 courses of HBO + drug therapy, 39 cases treated with a single session of HBO + drug therapy, and 32 treated with drug therapy alone. Motor development was assessed using the Chinese infantile intelligence development test scale at the ages of 3, 6 and 12 months. Results The sequential HBO + drug group achieved significantly better average motor development than the single session group or the drug only group. There was mo significant difference between the single treatment group and the drug only group. The proportion of abnormal CT results 12 months after treatment was significantly higher in the drug only group than in the sequential HBO + drug group. Conclusion Sequential HBO + drugs therapy with the improved oxygen mask is preferable to a single session of HBO + drug treatment or drug therapy alone.

OBJECTIVETo study the status of oral pharyngeal carriage and characteristics of Haemophilus influenzae (Hi) in healthy preschool children in Fuzhou.

METHODSSix hundred and three healthy children in two representative kindergartens in Fuzhou were studied as research subjects, and the rates of oral pharyngeal carriage of Hi were studied in four seasons. All Hi strains were serotyped and biotyped.

RESULTSThe oral pharyngeal carriage of Hi in day care nursery healthy children were 36.7% in winter, 18.0% in autumn, 12.4% in summer and 10.9% in spring respectively. Serotype Hib was preponderant in autumn (6.9%). In winter, the carriage rates of NTHi and Hib were 17.1%, 5.4% respectively. The carriage rates of other serotypes were low. Biotype VII and VIII were preponderant in autumn, spring and summer but biotype VII and VIII were decreasing evidently in winter.

CONCLUSIONThere was evident seasonal difference in the rates of oral pharyngeal carriage and type of Hi in healthy preschool children. The carriage rate of Hi strains was high in autumn and winter. Results suggested that while the inoculation of Hib-binding bacterial vaccine was expanded the study on new bacterial vaccine of Hi still needs to be augmented.
