Objective To investigate the relationship between gestational hypothyroidism and preeclampsia.Methods A retrospective study was conducted on 1 776 patients with gestational hypothyroidism,who gave birth in the International Peace Maternity & Child Health Hospital of China Welfare Institute,Shanghai Jiaotong University School of Medicine from January 2013 to December 2014.They were divided into three groups,including Improving Group (n=1 469),Progressing Group (n=133) and Remaining Group (n=174),based on their thyroid function at the first and third trimesters.Levels of thyroid hormones in the first and third trimesters were analyzed.Incidences of preeclampsia in those patients were calculated.And the correlation between thyroid function and incidence of preeclampsia was analyzed.T-test,Mann-Whitney U test,Chi-square test,variance analysis (SNK method) and Kruskal-Wallis H test or Logistic regression were performed for statistical analysis.Results (1) There were no statistical differences in age,gravidity and parity among the three groups.The pregestational body mass index in Progressing Group was lower than that in Improving group (21.1 ±2.9 vs 21.8±2.8,P＜0.05).(2) In the first trimester,the level of thyroid stimulating hormone (TSH) in Remaining Group was higher than those in Improving and Progressing Groups [(4.21 ± 1.69) vs (3.77±.3.03) and (2.00±0.57) mU/L,F=27.635,P＜0.01],and that in Improving Group was higher than that in Progressing Group (P＜0.05).The level of free thyroxine (FT4) in Progressing Group was higher than those in Improving and Remaining Groups [(16.18±9.67) vs (14.58± 1.71) and (14.54± 1.74) pmol/L,F=16.188,P＜0.01].In the third trimester,the TSH level in Remaining Group was higher than those in Improving and Progressing Groups [(5.07±0.86) vs (2.57±0.77) and (4.31 ±0.87) mU/L,F=28.986,P＜0.01],while the TSH level in Improving Group was higher than that in Progressing Group (P＜0.05).No statistical differences in FT4 levels (in the third trimester) and positive rates of thyroid peroxidase antibody (TPOAb) Were observed in the three groups.(3) Blood pressures (including diastolic and systolic blood pressures) in the first trimester and diastolic pressures in the third trimester showed no significant differences among the three groups.Systolic pressure of Improving Group in the third trimester was lower than that of Progressing Group [(119.4± 11.9) vs (121.8± 14.2) mmHg,P＜0.05,1 mmHg=0.133 kPa].(4) The incidence of preeclampsia in Progressing Group was higher than those in Improving and Remaining Groups [7.52％ (10/133) vs 1.29％ (19/1 469) and 3.45％ (6/174),x2=26.646,P＜0.01],and the incidence in Progressing Group was higher than those in Remaining and Improving Groups (both P＜0.05).The incidence of severe preeclampsia in Progressing Group was higher than that in Improving Group [6.02％ (8/133) vs 0.41％ (6/1 469),P＜0.05].There were no significant differences in incidences of mild preeclampsia among the three groups.(5) After adjusting for age,body mass index,gravidity and parity,the risk of severe preeclampsia in Improving Group was lower than that in Remaining Group (OR=0.233,95％CI:0.057-0.946,P＜0.05).Conclusions By improving thyroid function in pregnant women with hypothyroidism,the risk of preeclampsia,especially severe preeclampsia,could be reduced,which could improve maternal and neonatal outcomes.

Objective:To investigate the role of mTOR in regulation of ICOS expression in human blood regulatory T cells. Methods:Isolation of Treg cells from human PBMC using MACS beads. We detected the ICOS expression on purified Treg cells and Treg cells viability using flow cytometry in anti-CD3 plus anti-CD28 ( antibody or beads) or anti-CD3 plus ICOSL-Fc for 3 days and 7 days. CFSE labeling human PBMC cells and in vitro cultured Treg mixed, Treg contact inhibition activity was detected by flow analysis. Results:After in vitro stimulation of Treg cells in the presence of anti-CD3+anti-CD28 for 3 days, there was no significant statistic difference in viability between ICOS+(92. 00±2. 69)% and ICOS-(90. 30±3. 53)% Treg-cells. After cultured for 7 days,the decreased ICOS+ Treg cells percentage within total Treg cells from ( 40. 20 ± 1. 83 )% to ( 11. 60 ± 1. 10 )% compared with that of 3 days. Further more,the ICOS expression level between stimulated with anti-CD28 or ICOSL-Fc condition group,compared with the ICOS MFI in the condition of anti-CD3 plus anti-CD28 treatment for 3 days was (2410. 0±746. 4) obviously higher than (403. 30±74. 42), that of the group treated with anti-CD3 plus ICOSL-FC. Rapamycin could partially suppress Treg cells ICOS expression,but unaffected the Treg suppression ability. Conclusion:ICOS expression level may not important for in vitro cultured human PBMC Treg cells survival although mTOR signling is important for regulation ICOS expression on in-vitro cultured Treg cells,but the ICOS expression on Treg regulated by multiply signaling pathways. CD28 signaling is the key stimulation factor for ICOS upregulation on in-vitro cultured Treg cells compared to ICOSL signaling.

OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.

METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.

RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.

CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

·AIM: To investigate the efficacy and security of the silicone membrane implant through observing intraocular pressure, filtering blebs and histopathologic results.·METHODS; Forty rabbits were randomly divided into 4 groups. Each group consisted of 10 rabbits. Trabecu-lectomy and silicone membrane implantation were performed in one eye of each rabbit, while the other eye was only performed trabeculectomy as control. The change of intraocular pressure, filtering blebs were observed postoperatively. And each eye had undergone histopathologic examination.·RESULTS:The duration of low intraocular pressure and existence of filtering blebs in implanted eyes was longer than that in controlled eyes. Light microscopy revealed that patent drainage tract and biting site could be seen in silicone membrane implanted eye. The activity and regularity of fibroblast proliferation in implanted eyes and controlled eyes were similar. Excessive expression of fibroblast proliferation was not induced by silicone membrane.·CONCLUSION: Characterized by safety, effectiveness and simplicity, silicone membrane implantation can act as a new drainage surgery.KEYWORDS: silicone membrane; drainage surgery;intraocular pressure

Objective To explore the influence of smoking on olfactory disorder in Parkinson's disease (PD). Methods According to smoking or not, 167 PD patients ( PD group) and 100 normal controls ( normal control group) were divided into smoking subgroups and non-smoking subgroups.The olfactory identification threshold was tested by T&T olfactory assessment.Results Compared with normal control group, the scores of MMSE and montreal cognitive assessment in PD group were significantly decreased ( all P<0.05 ) , age, smoking history, the rate of male had no statistical significance ( all P>0.05 ) .The olfactory identification threshold in PD group was significantly higher than normal control group (t=6.785, P=0.000).Compared with PD smoking subgroup, the olfactory identification threshold in non-smoking subgroup was significantly higher (t=-3.000, P=0.003).The olfactory identification threshold in normal control smoking subgroup was significantly lower (t=0.784, P=0.435). The olfactory identification threshold of PD smokers had no correlation with smoking pack-years or duration ( r=-0.104, P=0.441;r=-0.156, P=0.246) .Conclusion Smoking may protect olfactory disorder in PD patients, and it has no correlation with smoking pack-years or duration.

We reviewed a case diagnosed with with chlorodifluoromethane poisoning (Freon-22) admitted to the Department of Nephrology, Xiangya Changde Hospitalin August, 2020, focusing on the clinical manifestations, laboratory examination, and course of treatment of patients, as well as discussing the clinical characteristics, treatment and prognosis of chlorodifluoromethane poisoning cases. The patient is a 29 years old male engaged in air conditioning maintenance work, with an acute onset. On the day of onset, the patient refilled chlorodifluoromethane poisoning refrigerant for a client's air conditioner and rested in a small car after work where he was found two hours later. At that time, the patient was experiencing impaired consciousness, vomiting and incontinence. After regaining consciousness, he presented with convulsions, dizziness, numbness of limbs and muscle aches, accompanied by a decrease in limb strength. The initial hospital examination indicated that impaired liver and kidney functionality, significantly elevated creatine kinase levels, and a little exudation in the sitting lung as shown by Chest CT, and no significant abnormalities found in the electroencephalogram (EEG) or electromyogram (EMG). Subsequent investigations revealed that the connecting pipe of the steel cylinder in the car was cracked due to high temperature, which led to the leakage of chlorodifluoromethane poisoning. After active treatment with hyperbaric oxygen, hormone, nerve nutrition and liver protection, the patient's condition improved and he was discharged from the hospital. After two-year follow-up, the patient still has mild numbness in both lower limbs. At present, there are few reports of Freon poisoning, and the clinical presentations can vary greatly, with severe cases even leading to death from poisoning. This paper summarizes and reports the clinical manifestations of a patient with chlorodifluoromethane poisoning, and reviews the related literature, with the aim to improve the clinician's understanding of the disease and make a timely and effective treatment plan.
