Objective To investigate the serum IL-33 level and its association with TH1,TH2,TH17 and Treg cells in patients with unexplained recurrent spontaneous abortion(URSA).Methods Forty-six URSA patients and 40 healthy controls were enrolled.The proportions of TH1,TH2,TH17 and Treg cells in peripheral blood samples were determined by flow cytometry,and serum IL-33 levels by ELISA.Results The levels of serum IL-33 in URSA patients were significantly lower than that in healthy controls.The proportions of TH2 and Treg cells in URSA patients were significantly lower than that in healthy controls (P ＜ 0.05),while the proportions of TH 1 and TH 17 cells in URSA patients were significantly higher than that in healthy controls.Serum IL-33 levels were negatively correlated with the proportions of TH 1 and TH17 cells,and positively with that of TH2 cells,while no correlation with Treg cells.Conclusion Serum IL-33 levels decrease significantly in URSA patients,and are correlated with the proportions of TH1,TH2 and TH17 cells,indicating that IL-33 may be associated with TH1,TH2 and TH17 cells in URSA patients.

Objective To investigate the effect of kinesio taping on upper crossed syndrome (UCS). Methods From December, 2016 to March, 2017, 52 patients with UCS were randomly divided into control group (n=26) and observation group (n=26). The control group re-ceived exercise therapy, and the observation group received kinesio taping in addition, for four weeks. They were assessed with Visual Ana-logue Scale (VAS), forward head angle (FHA) and forward shoulder angle (FSA). Results There was no significant difference in the score of VAS, FHA and FSA between two groups before treatment (P>0.05). After treatment, the scores of VAS, FHA and FSA significantly de-creased (t>2.804, P<0.05), and they were less in the observation group than in the control group (t>2.632, P<0.05). Conclusion Exercise therapy could relieve pain and correct abnormal posture of UCS, which is more effective combined with kinesio taping.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.

Most chemical medicines have polymorphs. The difference of medicine polymorphs in physicochemical properties directly affects the stability, efficacy, and safety of solid medicine products. Polymorphs is incomparably important to pharmaceutical chemistry, manufacturing, and control. Meantime polymorphs is a key factor for the quality of high-end drug and formulations. Polymorph prediction technology can effectively guide screening of trial experiments, and reduce the risk of missing stable crystal form in the traditional experiment. Polymorph prediction technology was firstly based on theoretical calculations such as quantum mechanics and computational chemistry, and then was developed by the key technology of machine learning using the artificial intelligence. Nowadays, the popular trend is to combine the advantages of theoretical calculation and machine learning to jointly predict crystal structure. Recently, predicting medicine polymorphs has still been a challenging problem. It is expected to learn from and integrate existing technologies to predict medicine polymorphs more accurately and efficiently.

Epigenetics is the study of heritable traits that are not involved in the changes in DNA sequences.It has been widely recognized that epigenetics plays multiple regulatory roles in diverse cellular activities and is associated with the occurrence and development of a variety of diseases.Following the human genome project (HGP),discoveries in the field of epigenetics reveal the complexity and accuracy of genetic regulation.Institute of Biomedical Sciences (IBS),which is affiliated with Fudan University Shanghai Medical School,has been attaching great importance to "Medical Epigenetics" since the establishment of IBS.In the past 12 years,a number of influential discoveries in medical epigenetics have been made,raising China's status in the field of epigenetics and contributing greatly to the disciplinary construction and talent cultivation of biomedical-related disciplines in Fudan University.In this review,a list of accomplishments in epigenetics in IBS were summarized.

Objective To investigate the mechanism of reverse redistribution (RR) on dipyridamole 201Tl myocardial perfusion studies in the patients with coronary artery spasm. Methods Twenty-six patients with coronary artery spasm and presented as RR on dipyridamole 201Tl myocardial perfusion studies were enlisted as RR group, while other 16 patients with no coronary artery stenosis nor RR were enlisted as control group. Dipyridamole test was repeated during coronary angiography. Corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) and TIMI myocardial perfusion grade (TMPG) were measured at RR related and non-RR related coronary arteries before and after dipyridamole infusion respectively.All of the data were analyzed by Student's t-test orχ2-test and correlation analysis. Results Coronary artery angiography showed slower blood flow and lower myocardial perfusion in RR related vessels when compared with non-RR related vessels in RR group, but there was no significant difference among the main coronary arteries in control group. The perfusion defects of RR area at rest were positively related to slowerblood velocity at corresponding coronary arteries ( r = 0.79, t = 10.18, P ＜ 0.001 ). In RR related vessels,CTFC were (36 ±6) frames and (26 ±7) frames (t =4.15, P ＜0.01 ), while TMPG were (2.02 ±0.39)grades and (2.92 ± 0.12) grades ( t = 2.25, P ＜ 0.05 ) before and after dipyridamole infusion, respectively.In non-RR related vessels, CTFC were (29 ±7) frames and (25 ±5) frames (t =2.31, P ＜0.05), while TMPG were (2.56 ± 0.31 ) grades and (2.96 ± 0.06) grades ( t = 2.17, P ＜ 0.05 ) before and after dipyridamole infusion, respectively. However, there were no significant changes of CTFC and TMPG before and after dipyridamole infusion in control group ( t = 0.932, 0.867, respectively, both P ＞ 0.05 ). Conclusion RR is related to the decreased blood flow and myocardial perfusion induced by coronary artery spasm at rest,which may be improved by stress test such as intravenous dipyridamole infusion.

Objective To identify the association between gestational weight gain and birth weight over the past 9 years in Kunshan city,Jiangsu province,China.Methods This population-based study was conducted between 2001 to 2009.Data were retrieved from Perinatal Monitoring System of Maternal and Child Health Care Hospital of Kunshan.The study population consisted of 33 631 women and singleton live fetus.Gestational weight gain was defined as the total weight gain during the last and first prenatal care program and divided by the interval weeks.Results From 2001 to 2009,the average incidence of low birth weight was 1.86％,while the average incidence of macrosomia was a bit higher,fluctuating around 8.47％.On those underweight mothers,after adjustment for potential confounders,and stratified by the BMI levels,which were evaluated at the first prenatal care program,we found that weight gain in the 3rd and 4th intervals,could reduce the risk of low birth weight (less than 2500 g).With those mothers with normal-weight,weight gain in the 2 rid,3 rd and 4th intervals,would reduce the risk of low birth weight.Risks in the 4th quantile among underweight and normal-weight group were prevalence odds radio (POR) 95％CI:0.51 (0.32-0.80) and 0.58 (0.42-0.79),respectively.The risks showed a significant downward trend in underweight and normal- weight groups with increased gestational weight gain.As for macrosomia (≥4000 g),the risks increased (POR 95％CI) 4.69(2.82-7.81 ) in underweight,4.15 (3.43-5.03) in normal-weight,in overweight,3.64 (2.62-5.06) and 1.96 (1.48-2.60) in obese mothers with increased levels of gestational weight gain.Trend tests indicated that the risks of marcosomia increased in all levels of BMI,with the increase of gestational weight gain.Conclusion Findings from this population-based study suggested that gestational weight gain could reduce the risks of low birth weight among underweight and normal-weight groups,while increase the risks of macrosomia in all parturients,as compared with lowest levels of gestational weight gain.
