Objective: To investigate the effects of lycopene on T lymphocyte subpopulations and pulmonary alveolar macrophagic (PAM) functions in rats with acute lung injury (ALI). Methods: Rats were randomly divided into the following groups. (1) Control group, (2) ALI model group, (3) Low dose group, (4) Mid dose group and (5) High dose group. Control group and ALI model group were treated with solvent of lycopene, and the other groups were gastrically incubated with lycopene. Thirty-five days later, control group were given physiological saline, ALI model group and lycopene administrated groups were injected with lipopolysaccharide (LPS) (6.0 mg/kg) to induce ALI. One hour, four hours or six hours after LPS or physiological saline challenged, abdominal aorta blood for measuring lymphocyte subpopulations and bronchoalveolar lavage fluid for measuring function of PAM were gathered respectively. Results: (1) At h 1, the percentages of CD3+,CD4+ and CD8+ of lycopene administrated groups compared with control group were not significantly different. At h 4, the percentage of CD4+ was similar to that at h 1. As for the percentages of CD3+, except high dose group [(28.8?9.9)%] was significantly lower, low dose, mid dose and ALI model group showed no significant difference compared with control group[(39.5?4.5)%]. The percentages of CD8+ of ALI model and lycopene administrated rats, separately (10.2?3.9)%,(10.3?2.8)%,(9.8?2.8)%,(10.1?3.5)%, had been significantly reduced compared with control group[(15.1?2.5)%]; between ALI model and lycopene ad-ministrated groups there was no significant difference. The instance at h 6 was the same as that at h 4. The percentage ratios of CD4+ T-lymphocyte to CD8+ T-lymphocyte of ALI model rats were not significantly different compared with control group or lycopene administrated groups at h 1 and h 6. At h 4, the ratio of the CD4 + and CD8 + in Low dose and Mid dose groups had significant difference and ALI model, high dose hadn’t when they were compared with control group. (2) Lycopene increased the phagocytic function of PAMs significantly at h 1(P

Objective To assess the efficacy and safety of mifepristone combined with oral or vaginal misoprostol for termination of pregnancy between 8 and 16 weeks of gestation. Methods This was a randomized, multi-center, open clinical trial. A total of 625 women at 8-16 weeks of gestation were randomized to receive 200 mg oral mifepristone followed by either oral misoprostol 400 μg every 3 hours or vaginal misoprostol 400μg every 6 hours for a maximum of 4 doses 36-48 hours later. There were 417 women in oral group with 198 at 8-9 weeks and 219 at 10-16 weeks, while 208 women in vaginal group with 99 at 8-9 weeks and 109 at 10-16 weeks. The outcome measures were the success abortion rate, induction to abortion interval, the amount of bleeding, reoccurrence of menstruation and adverse events. Results Abortion rate was significantly higher in vaginal group [98.1% (202/206)] than that in oral group [94.0%(390/415), P=0.023]; concerning termination of pregnancy at 8-9 weeks and 10-16 weeks respectively, there were no significant differences between oral and vaginal groups (P=0.156, P=0.073). The induction to abortion interval was no significant difference in oral and vaginal group in different gestational weeks ( P=0.238, P=0.273). The average induction to abortion interval was (4.1 ± 6.6) hours and (6.0 ± 4.5) hours respectively in terminating 8-9 weeks and 10-16 weeks of gestation. Concerning the amount of bleeding within 2 hours of placenta expulsion, there was significant difference between oral group [(63±46) ml] and vaginal group [(55 ± 45) ml] in terminating 8-9 weeks of gestation (P=0.047), while there was no significant difference between groups in terminating 10-16 weeks of gestation [oral group (76 ± 52) ml versus vaginal group (76 ± 61) ml, P=0.507]. The reoccurrence of menstruation was about 37 days in both oral and vaginal groups. Two cases of incomplete abortion were serious adverse events (SAE) relating to treatment. The common adverse events (AE) of nausea and vomiting were significantly higher in oral group [57.2% (239/417), 36.3% (151/417)] than those in vaginal group [45.4% (94/208), 26.1% (54/208); P=0.005, 0.011]. Conclusion Oral or vaginal misoprostol combined with mifepristone, is effective and safe for termination of pregnancy between 8 and 16 weeks of gestation.

Vestibular migraine (VM) is a type of paroxysmal vertigo with headaches. The condition is very common in clinical practice,but its pathophysiological mechanism is not fully understood. The clinical manifestations of VM vary greatly and are similar to or overlap with peripheral vertigo diseases such as benign paroxysmal positional vertigo (BPPV) and Meniere's disease (MD),and the neurological examinations of VM usually have no special findings. Therefore,there is no objective gold standard for diagnosis,and exclusive diagnoses are required. Due to the lack of high-level evidence-based studies on the treatment of VM,previous reviews may have been at serious risk of bias due to poor study quality and significant heterogeneity. Despite the poor quality of the overall evidence base for VM treatment,we have systematically performed a clinical practicability-oriented evaluation in this review on the evidence for various treatment options for VM. At the same time,we make treatment recommendations based on this evaluation,hoping to help clinicians in treating patients with VM.

Objective To evaluate the efficacy,bleeding profile and safety of low-dose levonorgestrel-releasing intrauterine system (LNG-IUS 8) in Chinese healthy women of childbearing age.Methods A multi-center,open-label,single-arm clinical trial conducted at 16 centres in China enrolled 773 healthy women of childbearing age (mean age 31.6 years old,range 18 to 40 years old),who demanded contraception,from April 2006 to June 2013.All women placed LNG-IUS 8 for 3 years and then been followed up at 3,6,9,12,18,24,30,36 months.The efficacy variables including pregnancy rate and expulsion rate were analyzed using life table,while observing adverse events (AE) to evaluate the safety.The bleeding profile happened during the study was assessed using 90-day reference intervals (World Health Organization criteria).Results Eight pregnancies occurred among 773 women,resulting in a overall Pearl index of 0.42 per 100 women years.The 3-year cumulative pregnancy rate was 0.37 per 100 women years and the 3-year cumulative expulsion rate was 1.99 per 100 women years.The number of women with bleeding/spotting reduced and the bleeding/spotting days declined over time.Totally 219 AE were reported related to LNG-IUS 8 placements.The most common AE were vaginal bleeding (8.2%,63/773)and the ovarian cyst (6.2%,52/773).LNG-IUS 8 had an improving effect on dysmenorrhea that the percentage of women with dysmenorrhea as well as the days of dysmenorrhea decreased over time.The percentage of women satisfied or very satisfied with LNG-IUS 8 was 87.2% (622/713).Conclusion LNG-IUS 8 is highly effective and safe for Chinese healthy women of childbearing age.

OBJECTIVE:To prov ide reference for the improvement of quality standards of Shiwei yipi granules. METHODS : According to the general rules of 2015 edition of Chinese Pharmacopeia (part Ⅳ),microscopic identification was used to identify Massa Medicata Fermentata and Galli Gigerii Endothelium Corneum ;TLC method was used to qualitatively identify Crataegi Fructus and Semen Raphani ;the content of sinapine thiocyanate in Semen Raphani was determined by HPLC. RESULTS :The microscopic characteristics were obvious for Massa Medicata Fermentata (palisade cells of testa and stone cells of testa )and Galli Gigerii Endothelium Corneum (irregular fragments ). The same fluorescent spots of Crataegi Fructus and Semen Raphani were displayed at the same position of ursolic acid ,sinapine thiocyanate control and Semen Raphani reference substance. The linear range of sinapine thiocyanate was 23.27-9 574.42 ng (r=1.000 0). The LOD and LOQ were of 0.50 μ g/mL and 1.68 μ g/mL, respectively. RSDs of precision ,repeatability,intermediate precision and stability tests (24 h)were all less than 1.5%. The average recoveries were 99.40%-100.89%(RSDs were 0.18%-0.49%,n=3). The contents of sinapine thiocyanate in 3 batches of Shiwei yipi granules were 0.086 4-0.220 6 mg/g,the average was 0.168 4 mg/g. CONCLUSIONS :The identification method of Massa Medicata Fermentata ,Galli Gigerii Endothelium Corneum ,Crataegi Fructus and Semen Raphani in Shiwei yipi granules as well as the method for content determination of sinapine thiocyanate in Semen Raphani are established successfully. The content of Semen Raphani in the Shiwei yipi granules is no less than 0.16 mg/g calculated by sinapine thiocyanate (C16H24NO·5 SCN).
