Objective To know the relationship between air quality and meteorological conditions in Sanming City,Fujian, China.Methods Based on the fixed point monitoring data of everyday air quality from Sanming Environmental Monitoring Center and the corresponding upper air synoptic chart from 2002 to 2006,the spatial and temporal distribution characteristics,the variation tendency of the ambient air quality and their relations with the meteorological conditions were analyzed by using Excel 2003 software.Results The air pollution in Sanming was serious,the PM10 was concluded as the predominant pollutant.The concentration of SO_2,NO_2 and PM10,which affected the air quality of Sanming,was higher during October—April,and it was lower during May—September.The concentration of the pollutants was higher in the urban areas eompared with the suburbs. Conclusion The air quality in Sanming is related to the variation of the synoptic system.The air quality under the warm shear line system is best and under low system is next-best;the air quality under the warm sector convergence system is worst and under continent high system is next-worst;the low-level wind direction has some effect on the variation of the air quality,the air quality in easterly wind is better than that in westerly wind.

0. 05). Conclusion On the CTA exams with 64-slice spiral CT, good CTA image quality can be acquired with reduced contrast dose and saline flush, thereby we can afford reliable diagnostic information for the clinicians.

OBJECTIVETo search for a method for increasing clinical therapeutic effect of acute large area cerebral infarction.

METHODSNinety-six cases were randomly divided into a comprehensive treatment group and a western medicine group, 48 cases in each group. The western medicine group were treated with routine western methods, dehydration for decreasing intracranial pressure, brain-protection, anti-platelet agglutination, improving circulation and expectant treatment, etc.; the comprehensive treatment group were treated with the routine treatment of western medicine combined with acupuncture, moxibustion and enema of Chinese drugs. The therapeutic effect was observed after treatment for 28 days.

RESULTSThe total effective rate was 68.8% in the comprehensive treatment group and 39.6% in the western medicine group with a very significant difference between the two groups (P < 0.01), and the score of the National Institute of Health's Stroke Scale (NIHSS) and the score of the Glasgow Coma Scale (GCS) in the comprehensive treatment group were better than those in the western medicine group (P < 0.001, P < 0.01).

CONCLUSIONCombined treatment of Chinese medicine and western medicine for large area cerebral infarction is better than simple western medicine, and it can significantly improve neurological defect of the patient and decrease death rate.

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52

OBJECTIVETo observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro.

METHODSWe collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.5, 1, 2, 4, 8 and 12 h. And the sperm viability was detected.

RESULTSVCL was significantly higher at 8 h (P < 0.05) and very significantly higher at 12 h (P < 0.01) in the SHENG MAI ZHUSHEYE + Hams-F10 group than in the Hams-F10 group. VSL, VAP and ALH were significantly increased in the former group at 4, 8 and 12 h as compared with the latter (P < 0.05). The sperm viability was significantly decreased in the Hams-F10 group at 12 h (P < 0.05).

CONCLUSIONSHENG MAI ZHUSHEYE can improve sperm movement parameters and increase sperm viability in vitro.

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.
