OBJECTIVE:To observe the clinical efficacy and safety of Azithromycin combined with Xiaoer xiaoji zhike oral so-lution in the treatment of mycoplasma pneumonia in children. METHODS:Data of 120 children with mycoplasma pneumonia were retrospectively analyzed and divided into observation group (63 cases) and control group (57 cases) by different treatment meth-ods. All children received conventional treatment(reducing fever,relieving cough and resolving phlegm). Based on it,control group received Azithromycin 10 mg/kg,intravenous infusion,once a day,after continuous infusion of 3 d,it stopped 4 d. Observation group additionally received Xiaoer xiaoji zhike oral solution,10 ml for children younger than 5 years old,15 ml for children in 5 years old or over,3 times a day. 1-week was regarded as 1 treatment course,and it lasted for 2-3 courses. Clinical efficacy in 2 group was observed,recovery time of clinical signs,reduction of the number of inflammatory cells before and after treatment were compared,and the incidence of adverse reactions during treatment was recorded. RESULTS:After treatment,the total effective rate in observation group was significantly higher than control group,fever clearance time,disappearance time of cough,rales and pulmonary lesions were significantly shorter than control group,with statistical significance(P<0.05). Before treatment,there was no significant difference in the number of eosinophils and serum C reactive protein (CRP) level (P>0.05). After 1 week treat-ment,the number of eosinophils and CRP level in 2 groups were significantly lower than before,and observation group was signifi-cantly lower than control group,with statistical significance(P<0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Azithromycin combined with Xiaoer xiaoji zhike oral solution shows good efficacy in the treatment of mycoplasma pneumonia in children,it can shorten the duration of clinical symptoms,improve the level of in-flammatory cells,and does not increase the incidence of adverse reactions.

Objective To discuss the change of bone resorption of primary nephrotic syndrome (PNS) patients with prednisone treatment, andα-D3 effects on it. Methods ①30 PNS patients diagnosed and 28 healthy people in our hospital were selected;blood and urine samples before and after enough prednisone (pred) treatment were collect-ed to detect the iPTH, calcium and urinary DPD. ②30 PNS patients after 6 weeks enough prednisone treatment were randomly divided into Pred +α-D3 group and Pred group. Results ① PNS group compared with healthy group, urine DPD excretion rate was significantly increased(P<0.05),and blood iPTH was significantly increased (P<0.01);blood calcium was similar to healthy group. ② PNS patient after treatment with pred compared with that before treatment, urine DPD excretion rate was significantly increased(P<0.01),and blood iPTH was signifi-cantly increased(P<0.01). There was no obvious change in blood calcium.③Pred+α-D3 group compared with Pred group, urine DPD excretion rate was significantly decreased(P<0.01),and blood iPTH was significantly de-creased(P<0.05). There was no obvious change in blood calcium. Conclusion α-D3 can effectively reduce bone resorption in PNS patients.

Objective To discuss the effect of early comprehensive development mode on physical, intelligence and mental development of premature infants, and explore the feasibility of comprehensive development mode of preterm infants generally applied in child care clinic. Methods 90 cases of premature infants in intervention group from the beginning of the hospital before the intervention, continuous monitoring and comprehensive intervention including general system health, parenting guidance, family activities, growth monitoring, intelligence assessment, individualized instruction, and so on, for the timely correction of the anomalies. The 90 infants in the control group were only given conventional child health care after 1 month of corrected age. Results The nervous system abnormalities were detected 192 person-times in control group, while 129 person-times in intervention group at 3 months old, the detected rate of nervous system anomaly was higher in the control group than that in the intervention group (χ2=14.574, P=0.000). The body length of the intervention group was (74.31± 2.34) cm, the control group was (72.82 ± 2.13) cm. The body weight of the intervention group was (9.42 ± 0.93) kg, the control group was (8.11 ± 0.90) kg at 12 months old. The growth of weight and length of intervention group were higher than those of control group. The difference was statistically significant ( t=4.467, 9.602, P < 0.05). The development quotient was also assessed, the big activity sport, fine motor, adaptability, social behavior, development quotient of intervention group were (96.40±7.83) points, (95.45± 7.87) points, (98.33±10.87) points, (105.65±7.51) points, (101.45±7.36) points, and the control group were (92.53±6.57) points, (89.27±8.02) points, (94.26±9.88) points, (100.31±8.13) points, (95.65±6.93) points. The difference was statistically significant (t=2.628-5.443, P < 0.05). Conclusions Application of integrated early childhood development in premature infants can find early neurodevelopmental deviations of children and contribute to early intervention on premature infants. Using a combination of family and outpatient intervention may reduce the incidence of neurological abnormalities, improve the level of development of the intelligence assessment and promote premature infant intelligence, motor development and social adaptation ability.

Objective To investigate the effect of local mild hypothermia on stress hormones in patients with acute cerebral hemorrhage.Methods 78 patients were randomly divided into two groups, mild hypothermia group (38 cases) and routine group (40 cases). Conventional treatment was used in both groups, and local mild hypothermia therapy was applied in mild hypothermia group. The concentrations of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), corticosteroid (CS) and aldosterone (ALD) in plasma pretherapy and at 3rd, 7th day after treatment were measured. The scores of clinical neurological deficit prior and at 3rd week after treatment were observed.Results The levels of plasma ACTH, CRH, CS and ALD prior treatment both in mild hypothermia and routine group were higher than those in healthy control group (all P

Objective To observe the effects of mild hypothermia on heat shock protein 70 (HSP70) and glial fibrillary acidic protein (GFAP) expression in cerebral tissue after cerebral ischemia and reperfusion. Methods 30 male Wistar rats were randomly divided into sham-operated group, normal temperature group and mild hypothermia group. The model of focal cerebral ischemia was made by middle cerebral artery occlusion (MCAO) method. After 2 h of MCAO following 48 h of reperfusion, HSP70 and GFAP positive neurons were detected by immunohistochemistry technique in ischemic regions of rats. Results Many necrotic neurons were appeared in normal temperature group and no necrotic neurons in sham-operated group. Fewer necrotic neurons were fond in mild hypothermia group than in normal temperature group. The positive cells of HSP70 and GFAP in sham-operated group and mild hypothermia group were less than normal temperature group. Image analysis revealed that the average optical density of HSP70 and GFAP in sham-operated group and mild hypothermia group was significantly lower than in normal temperature group (all P

Objective To investigate the effects of local mild hypothermia therapy on ECG QT dispersion(QTd)and myocardial zymogram in patients with acute cerebral hemorrhage.Methods 70 cases of acute cerebral hemorrhage were divided into local mild hypothermia group(35 cases)and routine treatment group(35 cases)randomly.Routine treatment was used in both groups,and the local mild hypothermia therapy was just applied in local mild hypothermia group.The changes of the ECG QTd and myocardial zymogram were observed before treatment and 1 week after treatment.Results The ECG QTd was shorten and the myocardial enzymes in serum were decreased significantly in both groups at the 1 week after treatment(P
