Objective To investigate the incidence of the common respiratory viruses in children with respiratory tract infection and to compare the results among different ages and to analyze the relationship between wheezing of children and various viruses.Methods Nasopharyngeal secretions of 618 children with respiratory infection hospitalized were assayed for 7 respiratory viruses, including respiratory syncytial virus ,adenovirus, influenza A virus, influenza B virus, parainfluenza virus Ⅰ 、 Ⅱ、 Ⅲ.Results (1) A total of 166 cases, affected with viral etiology,were detected in 618 samples,and the total positive rate was 26.86％.The most common virus was RSV (17.96％), followed by PIV Ⅲ (5.99％), IFA (1.62％), ADV (0.81％), PIV Ⅰ (0.49％).Moreover, 1 case infected with RSV and PIVⅠ was included, with the positive rate 0.16％.(2)The positive rates were different in various ages, with 14d ～ ＜ 1-year 35.04％, 1 ～ ＜ 3-year 18.25％, 3 ～ ＜ 6-year 17.11％ and ≥ 6-year 9.26％.(3) There were differences of positive rate of viruses among different respiratory infectious diseases, and capillary bronchitis occupied the highest percentage(47.37％).(4)Among all the detected children, infants were more likely to whee in auscultation of lung, and RSV was the primary etiology.Conclusion RSV,which was the primary viral etiology in children with wheezing, was the most common virus leading to respiratory infection of children, followed by PIV Ⅲ.In the children with respiratory tract infection, the viral infection tends to occur in younger children.

1,25(OH) 2 vitamin D 3 is the most effective status of vitamin D in the body.It will play a biological active role when it combines with the receptor of vitamin D. It is common in the chronic kidney disease patients who are lack of vitamin D. The research finds that among the chronic kidney disease patients, in addition to the classic role of vitamin D in regulating calcium and phosphorus metabolism, it can also protect the kidney and delay the progress of chronic kidney disease by blocking the renin-angiotensin system, inhibiting inflammation, reducing podocyte damage and delaying renal fibrosis, etc.This article summarizes the protection mechanism of Vitamin D in the chronic kidney diseases.

Objective: To explore the significance of union examination of blood serum liver cancer tracers in the early diagnosis of liver cancer. Methods: We observed and compared the level of blood serum liver cancer tracers armor embryo protein (AFP), crag algae glycosidase (AFU), armor embryo protein heteroplasmon (AFPL3) and γ-Gu Anxian transferase (γ-GT) in early time for primary liver cancer patients and hepatitis liver cirrhosis patients and those chronic hepatitis B patients who had liver cancer family history. Results: Finally among the 30 patients in the early liver cancer group, 23 were positive with AFP, 20 with AFU, 15 with AFPL3 and 21 with γ-GT. Five were found positive with blood serum AFP, AFPL3, AFU and γ-GT at the same time; 5 with AFP, AFPL3 and γ-GT, 5 with AFP, AFU and AFPL3; 7 with AFP, AFU and γ-GT. By contrast, in the control group, among the 30 hepatitis liver cirrhosis patients and those chronic hepatitis B patients with liver cancer family history, 11 were found positive with AFP, 3 with AFPL3, 12 with AFU and 14 with γ-GT. None of the patients were found positive with union examination of AFP, AFPL3, AFU and γ-GT in the blood serum at the same time. Conclusion: The union examination of AFP, AFU, AFPL3 and γ-GT is significant to the early diagnosis of primary liver cancer.

BACKGROUND:Traditional Chinese medicine plays a specific role in the clinical diagnosis and treatment of ischemia reperfusion injury. OBJECTIVE:To investigate the effect of Bu Yang Huan Wu Decoction on ischemia reperfusion injury in rats after replantation of of lower limbs, and evaluate the protective effect and mechanism of ischemic tissue. METHODS:A total of 120 Wistar rats were randomly divided into four groups:normal control (intragastric administration of saline after anesthesia), Bu Yang Huan Wu Decoction (intragastric administration of 10 mL/kg Bu Yang Huan Wu Decoction immediately after reperfusion), edaravone (intravenous administration of 10 mL/kg edaravone immediately after reperfusion), and blank control (intragastric administration of saline) groups. At 24 hours after reperfusion, the myeloperoxidase, lactate dehydrogenase, nitricoxide synthase, inducible nitricoxide synthase, constitutive nitricoxide synthase level in the blood were detected. At 1 week after reperfusion, the activity of superoxide dismutase in gastrocnemius tissue, nitrogen monoxidum and malondialdehyde, and the load of Ca2+were assayed. RT-PCR semiquantitative analysis was performed to detect bcl-2 mRNA and bax mRNA transcriptional levels in the gastrocnemius.RESULTS AND CONCLUSION:Bu Yang Huan Wu Decoction protected the rats from ischemia reperfusion injury by reducing the production of oxygen free radicals, reinforcing the activity of superoxide dismutase, lessening the calcium overload, decreasing the production of nitrogen monoxidum, up-regulating the expression of anti-apoptotic gene bcl-2, down-regulating the expression of pro-apoptotic gene bax, and attenuating the injury of skeletal muscle after ischemia reperfusion injury. Bu Yang Huan Wu Decoction has significant protection on cerebral ischemia reperfusion injury in rats after replantation of severed limb, which may be related to the scavenge of free radicals, inhibition of skeletal cells apoptosis, and attenuation of reperfusion injury.
