ObjectivesTo observe correlation between serum vitamin A status and prevalence or severity of NRDS. MethodsRecruited into this study were 166 preterm infants admitted to our neonatal department. The serum concentration of vitamin A was measured, and the prevalence of NRDS at different levels of vitamin A was compared. According to the clinical manifestation and X-rays, there were 30 infants diagnosed as NRDS. Another 30 patients from the rest 133 infants without NRDS were randomly selected as control group according to the gestational ages, then the difference between NRDS group and control group were observed according to gestational ages. The 30 preterm infants with NRDS were divided further into mild group (in-cluding stagesⅠandⅡ,n=18) and severe group (including stageⅢ andⅣ,n=12) according to ifndings chest X-ray, then the difference between these two groups were observed.ResultsIn the 166 preterm infants recruited, 65/166 had serum vitamin A lower than 0.35 μmol/L, in which 14/65 (21.54%) were NRDS patients. Another 93/166 patients had serum vitamin A ranged from 0.35 μmol/L to 0.7 μmol/L, in which 15/93 (16.13%) were NRDS patient. The rest 8/166 had serum vitamin A higher than 0.7 μmol/L, in which 1/8 (12.50%) were NRDS patient. However, the differences between each two groups were not signiifcant. When gestational ages ranged from 34 to 37 weeks, the serum concentrations of vitamin A of NRDS group were lower than that in controls (P<0.05). No signiifcant difference between the serum concentrations of vitamin A and the severity of NRDS were ob-served (P>0.05).ConclusionsThe prevalence of NRDS for those preterm infants lacking of vitamin A was tended to increase. And the late preterm infants (34 w≤ GA <37 w) with vitamin A deifciency are prone to NRDS.

BACKGROUND: Focal adhesion kinase (FAK) phosphorylation influences the proliferation, migration and apoptosis of cells. However, there are no reports about the role of FAK phosphorylation in migration and proliferation of vascular smooth muscle cells during the process of vascular restenosis.OBJECTIVE : To analyze the correlation between FAK phosphorylation and vascular remodeling after balloon endothelial denudation in rats.DESIGN: Random controlled experiments in animals.SETTING: Cardiology Institute of Xianning College; Shenzhen Center for Chronic Disease Prevention and Control;Department of Cardiology at the Affiliated Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology.MATERrALS: The experiment was carried out in the Laboratory of Cardiology at the Affiliated Tongji Hospital from March to May in 2005. Forty male Wistar rats were used in the study, and they were managed according to the ethical standard of animals.METHODS: ①Forty rats were randomized into five groups (n =8): non-balloon endothelial denudation control group, and 4-day, 8-day, 16-day and 24-day model groups after balloon endothelial denudation. ②The rat models of restenosis following balloon endothelial denudation were built. At days 4, 8, 16 and 24 postoperatively, the denudated vessels were harvested for the detection of the morphological changes, which were taken as the judgment of successful models;Western blot method was used to detect the expression and activity of FAK. Abdominal aorta of left common carotid in rats was served as controls.MAIN OUTCOME MEASURES: The expressions of FAK and phosphorylation FAK in rat artery.RESULTS: Totally 40 rats were all involved in the result analysis.①A small quantity of FAK without phosphorylation could be detected in the controlled rats. Compared with the control group, the expression and activity of FAK in the model group rapidly increased at 4 days after balloon injury (P ＜ 0.05), and they changed in a similar manner with the increase of injury duration. The expression of FAK reached a peak at 8 days and began to descend at 16 days. The expression of phosphorylation FAK reached a peak at 16 days and then rapidly descended. ②Focal hyperplasia of intima was found at 8 days after balloon endothelial denudation, and diffuse hyperplasia of intima was found at 16-24 days after denudation.CONCLUSION: FAK can take part in vascular remodeling after balloon endothelial denudation in rats. The level of intimal hyperplasia is closely associated with the level of FAK and FAK phosphorylation.

Objective To investigate the clinical efficacy of Lu’s warm needling in treating perimenopausal syndrome.Methods Sixty patients with perimenopausal syndrome were randomly allocated to treatment and control groups, 30 cases each. The treatment group received Lu’s warm needling and the control group, conventional acupuncture. The scores of Kupperman Index (KI), Pittsburgh Sleep Quality Index (PSQI) and Hamilton Depression Scale (HAMD), and serum estrogen (E2), follicle stimulating hormone (FSH) and luteal hormone (LH) were observed before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 80.0% in the treatment group and 53.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the KI score in the two groups (P<0.01). There was a statistically significant difference in pre-/post-treatment KI score difference value between the treatment and control groups (P<0.05). There were statistically significant pre-/post-treatment differences in serum LH, FSH and E2 contents in the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the Hamilton Depression Scale score and the Pittsburgh Sleep Quality Index score in the two groups (P<0.01, P<0.05). There was a statistically significant post-treatment difference in the Hamilton Depression Scale score between the treatment and control groups (P<0.05).Conclusion Lu’s warm needling is an effective way to treat perimenopausal syndrome.
