OBJECTIVETo evaluate effectiveness therapeutic regimens for obstructive sleep apnea hypopnea syndrome (OSAHS) children at an acceptable cost.
METHODThis study was performed at Yuying Children's Hospital of Wenzhou Medical University from Mar. 2008 to Dec. 2010. Prospective random number table method was used for the analysis; 60 children with mild OSAHS were divided into Mild OSAHS Montelukast Treatment (MM) group and Mild OSAHS Adenotonsillectomy Treatment (MAT) group. 32 children in MM group were treated with leukotriene receptor antagonists (LTRAs), while 28 children in MAT group were treated with adenotonsillectomy. Also, 58 children with moderate and severe OSAHS were divided into severe OSAHS Montelukast Treatment (SM) group and severe OSAHS Adenotonsillectomy Treatmen (SAT) group. Twenty-two children in SM group were treated with LTRAs, while 36 children in SAT group were treated with adenotonsillectomy. All selected children were evaluated by polysomnography (PSG) and Obstructive Sleep Apnea-18 (OSA-18) items before and after a six-month treatment. Both records were taken and analyzed, surgical complications and the reason for non-remission after operation were also analyzed. Two therapies were compared based on economic consideration and therapeutic effect. Result (1) PSG: A significant change of a significant change of Apnea Hypopnea Index (AHI) was observed in MM group after the treatment (before receiving the treatment 4.56 ± 1. 26, and after receiving the treatment 3. 48 ± 1. 52, t =3. 50, P <0. 05). But for oxygen desaturation Index (ODI) (MM group 2. 18 ± 2. 19, and MAT group 1. 80 ± 2. 34) and Lowest Oxygen satuation (LSaO2) (MM group 91. 66 ± 2. 34, and MAT group 92. 79 ± 2. 18), there was no significant difference in MM group and MAT group after the treatment (ODI, t =0. 65, and LSaO2 t = - 1. 93, P >0. 05). (2) OSA-18 scores: Significant differences were found in sleeping disorder (before 14. 81 ± 6. 28, and after 10. 56 ± 3. 57), the degree of familial stress (before 13. 56 ± 3. 54, and after 8. 97 ± 2. 96), and OSA-18 total scores (before 52. 66 ± 1. 11, and after 42. 56 6. 48) in MM group after the treatment (sleeping disorder Z - 3. 14, the degree of familial stress Z = -4. 50, and OSA-18 total scores Z= -4. 01, P <0. 05). (3) In addition to the cost of drugs, groups with surgical treatment had a larger economic burden than those with LTRAs treatment. (4) Treatment was totally effective for 28 children (88%) in MM group, and 28 children (100%) in MAT group. Meanwhile, treatment also achieved an obvious effect on 2 children (9%) in SM group, and in 35 children (97%) in SAT group. In MAT group, 3 children improved (11%). And in SAT group, 7 children improved (19%), but treatment was found to be ineffective in 1 case (3%). Among those effective and ineffective cases in groups with surgical treatment, there were 9 children with nasal diseases.
CONCLUSION(1) Surgical treatment is recommended as the first choice for children with moderate and severe OSAHS. And for those who also suffer from nasal diseases, treatment combining drugs with surgery is necessary. (2) LTRAs therapy has a good effect for mild OSAHS. Surgery is also recommended when drugs could not achieve any obvious improvement in clinical symptoms of children with mild OSAHS.

Objective To investigate the effect of nitric oxide synthase(NOS) inhibitors and L-arginine(L-Arg) on the prognosis of traumatic shock in rats. Methods Traumatic shock models of Sprague-Daulay rats were made and randomly devided into control group (n=24),L-NAME treatment group (n=24),AG treatment group (n=24) and L-Arg treatment group (n=24). Serum nitric oxide(NO) levels and oxygen partial pressure in tissues include skeletal muscles,liver and small intestine were detected at 1h,3h,5h after resuscitation. Meanwhile, hemodynamic data of the rats and their survival rates of 12h and 24h were monitored and recorded. Results Serum NO concentration was statistically lower after resuscitation in L-NAME group than that in control group, while there were no statistical significance of tissues oxygen partial pressure and survival rate in 12、24h between the two groups. AG could decrease serum NO levels only at late stage of traumatic shock,but no effect on the synthesis and relase of NO at early stage of traumati shock.AG could improve tissues oxygen partial pressure of the liver and small intestine, and prolonged the mean survival time. L-Arg could increase serum NO levels, and improve oxygen partial pressure of intestine and significantly increase the survival rate at 12h and 24h in rats with traumatic shock. Conclusions Treatment with AG and L-Arg can improve the prognosis of traumatic shock rats much better than that with L-NAME.

This study was aimed to observe the effects ofTian-ShuDripping Pills (TSDP) on cerebral hemodynamics among anesthetized dogs, in order to demonstrate its clinical treatment functional correlation on angioneurotic headache. A total of 25 hybrid dogs were randomly divided into the normal saline (NS) group, TS capsule (positive control: 0.4 g·kg-1 crude medicine) group, low-dose TSDP (0.2 g·kg-1 crude medicine) group, middle-dose TSDP (0.4 g·kg-1 crude medicine) group, and high-dose TSDP (0.8 g·kg-1 crude medicine) group.Intraduodenal administration was given once under anesthesia. Changes of mean arterial blood pressure, blood flow of vertebral artery and internal carotid artery blood flow were detected and the cerebral blood flow and cerebral vascular resistance were calculated. The results showed that TSDP of low-dose, middle-dose and high-dose group can significantly reduce the cerebral vascular resistance and increase the cerebral blood flow within 180 min after medication. It was concluded that TSDP can improve the cerebral blood circulation of anesthetized dogs. Its mechanism may be through the reduction on cerebral vascular resistance and increasing of cerebral blood flow.

Objective To evaluate the effectiveness of psychological health intervention in the elderly urban residents living on minimum subsistence allowances, and to search for a suitable psychological health intervention strategy. Methods The 112 elderly persons living on minimum subsistence allowances in Xuzhou were selected by stratified cluster sampling, and they were matched with 112 controls. The elderly persons living on minimum subsistence allowances were divided into intervention group and control group. A general intervention based on community involved psychological health and care lecture, psychodrama treatment and psychological consultancy was made on the intervention. The SCL-90 was used to evaluate the psychological health status and effectiveness of psychological health intervention. Results The elderly persons living on minimum subsistence allowances had higher SCL-90 scores compared with other residents, and their psychological health status was serious. After the psychological health intervention, the SCL-90 scores were all lower in intervention group than in control group [ interpersonal relationship sensitiveness: (1.13 ± 0. 39) vs.(1.26±0.26), t=2.12, P=0.04; gloom: (1.23±0.66) vs. (1.43±0.24), t=2.08, P=0.04;anxiety: (1. 18±0.50) vs. (1.38±0.34), t=2.17, P=0.03; hostility: (1.24±0.49) vs. (1.40±0.28), t=2.03, P=0.04; other factor: (1. 31±0.56) vs. (1.49±0.31), t=2.04, P=0.04; total score: (115.89± 17.21) vs. (122.64± 10.41), t=2.42, P=0.02]. Conclusions The psychological health parameters are improved by psychological health intervention.
