Objective:To investigate the efficacy of oseltamivir combined with LianhuaQingwen granule in the treatment of influenza. Methods:Ninety-two patients with influenza who received treatment in Wenzhou People's Hospital from October 2017 to October 2019 were included in this study. They were randomly assigned to receive treatment with Lianhua Qingwen granules (control group, n = 46) or Lianhua Qingwen granules combined with oseltamivir (study group, n = 46) for 5 d. After treatment, clinical efficacy and symptom disappearance time (fever disappearance time, cough disappearance time, sore throat disappearance time) were compared between the control and study groups. Changes in immune function [C-reactive protein, interleukin-6, T lymphocyte subsets (CD 4+/CD 8+)] after treatment relative to before treatment, and the incidence of adverse reactions were compared between the two groups. Results:After treatment, total effective rate in the study group was significantly higher than that in the control group [97.83% (45/46) vs. 71.74% (33/46), χ 2 = 12.132, P < 0.001]. Fever disappearance time, cough disappearance time, sore throat disappearance time in the study group were significantly shorter than those in the control group [(2.04 ± 0.51) d vs. (3.15 ± 1.22) d, (3.25 ± 1.10) d vs. (4.53 ± 1.36) d, (2.72 ± 0.84) d vs. (3.95 ± 1.02) d, t = 5.693, 4.963, 6.313, all P < 0.001]. After treatment, C-reactive protein and interleukin-6 levels in the study and control groups were significantly decreased compared with before treatment [(9.24 ± 2.51) mg/L vs. (3.32 ± 2.21) mg/L, (9.21 ± 2.46) mg/L vs. (5.52 ± 2.10) mg/L, (70.25 ± 25.10) mg/L vs. (47.57 ± 14.50) mg/L, (69.24 ± 25.43) mg/L vs. (55.23 ± 16.44) mg/L]. After treatment, C-reactive protein and interleukin-6 levels in the study group were significantly lower than those in the control group ( t = 5.307, 3.138, all P < 0.001). After treatment, the number of CD 4+/CD 8+ cells in the study and control groups was significantly increased compared with before treatment [(0.45 ± 0.21) vs. (1.77 ± 0.59), (0.46 ± 0.18) vs. (1.08 ± 0.42)]. After treatment, the number of CD 4+/CD 8+ cells in the study group was significantly higher than that in the control group ( t = 14.295, 9.202, both P < 0.001). There were no significant differences in the incidence of nausea, vomiting, rash and diarrhea between the two groups within 5 d of treatment (all P > 0.05). Conclusion:Oseltamivir combined with Lianhua Qingwen granules exhibits better therapeutic effect than Lianhua Qingwen granules alone. It can strengthen immune function and shorten the durations of fever, cough and sore throat in patients with influenza.

New investigations indicated that half of the people in the world had the risk of vitamin D deficiency.The main reasons for vitamin D deficiency was that people ignored the importance of using vitamin D supplement in special ages and seasons.Children were potentially at high risk for vitamin D deficiency.Vitamin D deficiency during childhood could cause rickets,growth retardation,skeletal deformities and might increase the risk of osteoporosis and hip fracture in later life.Vitamin D deficiency were also related with cancer,autoimmune disease,endocrine system disease,nervous system disease,hypertension and infection.

Objective To study the expression of urokinase-type plasminogen activator (uPA) and its relation with expression of receptor (urokinase-type plasminogen activator receptor uPAR) in epithelial ovari- an cancer (OEC) and with the clinic prognosis.Methods Expression of uPA and uPAR protein was detected by Streptavidin-biotin-HRP in 68 cases of epithelial ovarian cancer and compared with that in 10 cases of borderline tumor,10 cases of benign tumor and 10 cases of normal tissue,and correlation between them was analyzed.The different expression groups of uPA was correlated with the prognosis of ovarian epithelial can- cer.The expression of uPA showed a correlation with short survival time (P

Objective To compare the efficacy and complications of percutaneous nephroscope decortication of cystic renal disease with transureteroscopic decompression of cystic renal disease.Methods Retrospectively analyze the clinical data of 42 simple renal cyst cases,who under treatment of surgical in Zhongnan Hospital of Wuhan University from Sep.2010 to Sep.2014 via percutaneous nephrolithotomy as well as ureteroscope.There were 21 patients in each group.Comparisons were made between the two groups on operation time,peripheral tissue injury,blood loss,postoperative infection,hospitalzation time.Postoperative recurrence were followed up.Results For the percutaneous nephroscope decortication of cystic renal disease group and transureteroscopic decompression of cystic renal disease group,the operation time were (38.43 ± 9.76) minutes,(28.95 ± 8.67) minutes,the number of tissue injury were 8,6;the blood loss were (28.62 ± 9.82) mL,(23.48 ± 7.65) mL;the number of postoperative infection was 4,10;the postoperative recurrence were 2,5;the hospitalzation time were 2 days and 8 days.Compared with the transureteroscopic decompression group,the percutaneous nephroscope decortication group had a less postoperative infection and fewer postoperative recurrence (P ＜ 0.05).But the operation time was longer in the percutaneous nephroscope decortication group (P ＜ 0.05).Conclusions The therapeutic effect of percutaneous nephroscope decortication is much better than that of transureteroscopic decompression,but also has a little disadvantage.

Objective To investigate whether leukotriene D4 (LTD4) regulates eotaxin-3 (Eot-3) expression in bronchial epithelial cells, and study effect of pranlukst on the regulation.Methods BEAS-2B cells and normal human bronchial epithelia cells were pre- treated with LTD4 for 1 hour,stimulated with interleukin-4, the cells were incubated for 24 hours. Eot-3 protein in supernatant were measured by enzyme linked immunosorbent assay(ELISA). The cells were pretreated with pranlukast in different concentration, then the above procedure was repeated. Results The untreated bronchial epithelial cell expressed Eot-3 protein on a very low level. After stimulating with IL-4 and incubating for 24 hours, Eot-3 production increased significantly. Pretreating the cells with LTD4 enhanced the inducing effect of IL-4. Pranlukast inverted the upregulation of LTD4. Conclusions Upregulating the expression of Eot-3 induced by IL-4 on bronchial epithelial cells may explain partially the mechanism of leukotrienes involving airway allergic inflammation of asthma. The invertion impact on upregulation of LTD4 by pranlukast may be one of mechanisms that leukotrienes receptor antagonist cure asthma.

Objective To observe the relationship of IL-10 gene single nucleotide polymorphism and the susceptibility to ALL. Methods The bone marrow and peripheral blood samples from 115 ALL patients and 323 healthy controls were collected in Peking University First Hospital and Beijing Dao-pei Hospital from January 2007 to December 2009. The DNA were extracted from all samples. The primers of -819C/T and -592A/C in the promoter region of IL-10 gene were designed for the PCR. The restrictive fragment length polymorphism of IL-10 gene was analyzed by using restrictive enzyme Msl Ⅰ and HpyCH4 Ⅲ.Sequencing was done in part of these samples to confirm the results of PCR. The differences of genotypes and allele ratio of -819 and -592 sites were analyzed between the ALL patients and healthy controls. Real-time quantitative PCR was performed to detect the EB virus (EBV) infection and the expression of BCR/ABL fusion gene. The differences of genotypes and allele ratio of -819 and -592 sites were analyzed between the positive and negative group. Results The genotype ratios of -819CC, -819TT, - 819CT, -592AA,- 592CC and - 592AC were 14. 8% ( 17/115 ), 45.2% ( 52/115 ), 40. 0% ( 46/115 ), 43.5% ( 50/115 ),16. 5% ( 19/115 ), 40. 0% ( 46/115 ) in ALL patients, and were 9. 9% ( 32/323 ), 16. 4% ( 53/323 ),73.7% ( 238/323 ), 11.8% ( 38/323 ), 15.5% ( 50/323 ), 72. 8% ( 235/323 ) in the healthy controls,respectively. The genotypes of -819 and -592 sites had statistically significant differences between the two groups(x2 values were 46.000 and 54.550, all P ＜ 0. 05 ). The allele ratio of -819T and -592A were (65.2%, 150/230) and (63.5%, 146/230) in ALL patients, while they were 53.5% (344/646) and 48. 1% (311/646)in the healthy controls. There were statistically significant differences between the two groups (x2 values were 9. 877 and 15.986, all P ＜ 0. 05 ). The EBV DNA were detected in 42 ALL patients,among which 22 were positive and 20 were negative. The genotype ratios of -819CC, -819TT, -819CT,-592AA, - 592CC, - 592AC in EBV positive group were 9. 1% ( 2/22 ), 40. 9% ( 9/22 ), 50. 0%(11/22) ,31.8% ( 7/22 ), 13.6% ( 3/22 ), 54. 5% ( 12/22 ), while they were 35.0% ( 7/20 ), 45.0%(9/20) ,20. 0% (4/20) ,35.0% (7/20) ,45.0% (9/20) ,20. 0% (4/20) in the EBV negative group.

The genotypes of -819 and -592 sites showed no statistical differences between the two groups ( all P ＞ 0. 05 ). Conclusion The population with - 819TT and - 592AA genotype of IL-10 gene shows susceptibility to ALL.

This study was carried out to evaluate the anti-inflammatory and free radical scavenging activities of flavans from flex centrochinensis S. Y. Hu in vitro and their structure-activity relationship. LPS-stimulated RAW 264.7 macrophage was used as inflammatory model. MTT assay for cell availability, Griess reaction for nitric oxide (NO) production, the content of TNF-alpha, IL-1beta, IL-6 and PGE, were detected with ELISA kits; DPPH, superoxide anion and hydroxyl free radicals scavenging activities were also investigated. According to the result, all flavans tested exhibited anti-inflammatory effect in different levels. Among them, compounds 1, 3, 4 and 6 showed potent anti-inflammatory effect through the inhibition of NO, TNF-alpha, IL-lp and IL-6, of which 1 was the most effective inhibitor, however, 2 and 5 were relatively weak or inactive. The order of free radical scavenging activities was similar to that of anti-inflammatory activities. Therefore, these results suggest that 3, 4 and 6, especially of 1, were,in part responsible for the anti-inflammatory and free radical scavenging activity of Ilex centrochinensis. Hydroxyl group at 4'-position of B-ring plays an important role in the anti-inflammatory and free radical scavenging capacities.
