Objective To compare the outcomes of multifetal pregnancy reduction (MFPR)performed at different gestational ages,and to analyze the influence on pregnancy outcomes.Methods Data of 302 women with multifetal pregnancies conceived after assisted reproductive technology (ART) from January 2002 to February 2012 in Department of Obstetrics and Gynecology of Provincial Hospital Affiliated to Shandong University were collected and divided into two groups.The study group involved 152 multifetal pregnancy cases (triplets or quadruplets),which were further divided into three subgroups according to the timing of MFPR to twins,12-13 +6 (n=91),14-15+6(n=32) and 16-24+6 gestational weeks (n=29).The control group involved 150 twin pregnancy cases.MFPR was performed by trans abdominal intra cardiac injection of 10％ potassium chloride (KCl) solution under ultrasound guidance.Gestational age of delivery,birth weight,incidence of gestational diabetes mellitus (GDM) and hypertensive disorder complicating pregnancy (HDCP) were analyzed by t test,one-way ANOVA or Chi-square test.Results Pregnancy loss rate of the study group (14.5％,22/152) was higher than that (6.7％,10/150) of control group,x2=4.857,P＜0.05.Pregnancy loss rate of the subgroup undergoing MFPR during 16-24+6 gestational weeks (31.0％,9/29) was higher than that during 12-13 +6 gestational weeks (8.8％,8/91,x2=7.212,P＜0.05) and that of control group (x2=12.749,P＜0.05).There were no differences in pregnancy loss rate between control group and MFPR during 12-13+6 gestational weeks (x2=0.370,P＞0.05),and during 14-15+6 gestational weeks (15.6％,5/32,x2 =1.739,P＞0.05).No statistically significant difference was found between the study group and control group in mean gcstational age at delivery[(36.9±l.8) weeksvs (37.0±1.8) weeks,t =-0.346,P＞0.05],mean birth weight of large babies [(2720.4±455.0) g vs (2729.1±413.8) g,t =-0.163,P＞0.05] and small babies [(2409.2±412.6) g vs (2416.2±436.8) g,t=-0.136,P＞0.05].There were no differences between the study group and control group in delivery rate at 28-34 gestational weeks [6.2％ (8/130)vs6.4％ (9/140),x2 =0.009,P＞0.05],birth weight discordance rate [12.3％ (16/130) vs11.4％ (16/140),x2=0.050,P＞0.05],GDMrate[3.1％ (4/130) vs2.1％ (3/140),x2 =0.659,P＞0.05] and HDCP rate [11.5％ (15/130) vs 8.6％ (12/140),x2 =0.010,P＞0.05].Conclusions There is risk of pregnancy loss after MFPR,but MFPR before 16 weeks of gestation might decrease the risk.

Objective · To explore the relationship between baseline lipid profiles and long-term cardiovascular outcomes after intervention with hypoglycemic drugs metformin and glipizide and to detect lipid components that can predict the long-term cardiovascular effect of metformin and glipizide.Methods· Liquid chromatography-quadrupole time of flight-mass spectrometry (LC-QTOF/MS) was used to measure 119 lipid components in baseline serum for 116 patients with type 2 diabetes (T2DM) and atherosclerotic heart disease (CHD) who were treated with glipizide (56 cases,the glipizide group)or metformin (60 cases,the metformin group).Cardiovascular complex end points (including cardiovascular death,all-cause death,nonfatal myocardial infarction,nonfatal stroke,and arterial revascularization) of all patients were followed up.The relationship between lipid components and cardiovascular complex end points was analyzed with Logistic regression analysis.The category-free net reclassification index (cfNRI) and the integrated discrimination improvement (IDI) were used to evaluate whether lipid components are helpful for predicting the recurrent cardiovascular events.Results· The differences in baseline drug distribution,clinical characteristics,and biochemical indexes between two groups were not statistically significant,except for diuretics use,serum PC (O-34:2) level,and SM (d18:0-24:0) level.Logistic regression analysis showed that baseline ChE (20:4) was a protective factor for recurrent cardiovascular events in the glipizide group (OR=0.87,P=0.039).ChE (20:4) significantly increased the cfNRI and IDI of cardiovascular complex end points by 69％ and 0.07,respectively (P=0.011,P=0.028).Baseline SM (dl 8:1-22:0) was a risk factor for recurrent cardiovascular events in the metformin group and all participants (OR=1.65,P=0.039;OR=1.64,P=0.014).SM (d18:1-22:0) significantly increased the cfNRI of cardiovascular complex end points in the metformin group and all participants by 74％ and 55％,respectively (P=0.012,P=0.005).Conclusion· Of 119 lipid components measured with LC-QTOF/MS,baseline ChE (20:4) is a protective factor and SM (d18:1-22:0) is a risk factor for cardiovascular complex end points in with T2DM and CHD patients after long-term treatment with metformin and glipizide.Both lipid components are helpful for improving the prediction of recurrent cardiovascular events.

Objective To explore the possible correlation between serum highly sensitive C reactive protein (hs CRP) and blood glucose, insulin, lipids ,insulin sensitivity index (SI),acute insulin response(AIR), and adiponectin in subjects with impaired glucose tolerance (IGT) or newly diagnosed type 2 diabetes mellitus(DM). Methods SI and AIR were assessed by the reduced sample number of Bergman′s minimal model method by intravenous glucose tolerance test in subjects. Meanwhile body mass index (BMI), waist hip ratio (WHR), the serum lipid profile, hs CRP, adiponectin levels were measured. Results Compared with normal control (NC) group[SI(6.6?2.4) 10 -4 (min?mU/L) -1 ,adiponectin7.77(6.35 10.70 mg/L),hs CRP0.40(0.21 1.67mg/L)], the SI and serum adiponectin in IGT group [(1.5?1.1) 10 -4 (min?mU/L) -1 , 4.29(3.59 6.22 mg/L) respectively] and type 2 DM group [(1.5?1.0)?10 -4 (min?mU/L) -1 , 3.46(2.37 4.72 mg/L) respectively] were significantly decreased (all P

Betacellulin (BTC) is one of "islets regeneration factors" which received more and more attention these years. BTCe is the C-terminal 50-residue region of mature BTC protein and can bind with erbB-1?erbB-4 receptor. It has the same mitogenic activity on cells as the whole section. BTC and BTCe can improve the level of glucose-stimulated insulin secretion (GSIS) during islets culture in vitro though they had no effect on the acute insulin secretion. BTCe also effectively ameliorated the hyperglycemia of STZ-induced diabetic rats by a single plasmid injection into muscle of rats. It is supposed that BTCe promote the proliferation of PDX-1 positive cells or repair some signal transduction pathway. Perhaps the latter is more important.

Standard therapy has not been established for thyroid cancer when a thyroidectomy is contraindicated due to systemic disease. Herein, we reported a patient who had hypertrophic cardiomyopathy and papillary thyroid carcinoma treated by radiofrequency ablation because of inability to tolerate a thyroidectomy. Radiofrequency ablation can be used to treat thyroid cancer when surgery is not feasible, although the long-term outcome needs further observation.

OBJECTIVE: To analyze the clinical features and genetic variants in four neonates with very long chain acyl-coenzyme A dehydrogenase (VLCAD) deficiency. METHODS: Neonates with a tetradecenoylcarnitine (C14:1) concentration at above 0.4 μmol/L in newborn screening were recalled for re-testing. Four neonates were diagnosed with VLCAD deficiency by MS-MS and genetic testing, and their clinical features and genotypes were analyzed. RESULTS: All cases had elevated blood C14:1, and the values of first recalls were all lower than the initial test. In 2 cases, the C14:1 had dropped to the normal range. 1 case has remained at above 1 μmol/L after the reduction, and the remainder one case was slightly decreased. In total eight variants of the ADACVL genes were detected among the four neonates, which included 5 missense variants and 3 novel variants (p.Met344Val, p.Ala416Val, c.1077+6T>A). No neonate showed salient clinical manifestations. CONCLUSION Above findings have enriched the spectrum of ADACVL gene mutations and provided a valuable reference for the screening and diagnosis of VLCAD deficiency.

Objective:To investigate the effect of dapagliflozin on cognitive function in middle-aged and elderly type 2 diabetes mellitus patients and related factors.Methods:This was a retrospective study. A total of 200 patients who were hospitalized in the Department of Endocrinology, the Second Affiliated Hospital of Anhui Medical University from August 2021 to August 2022 were recruited randomly. They were divided into the dapagliflozin group and control group. Clinical data were collected; plasma levels of β-amyloid protein(Aβ) 40 and Aβ42 were measured. The Montreal cognitive assessment(MoCA) and the mini-mental state examination(MMSE) were employed to assess cognitive function in both groups. Based on MoCA scores, patients in the dapagliflozin group were further categorized into mild cognitive impairment(MCI) and non-MCI subgroups. Differences among groups were analyzed and compared using t-test, χ2 test, and Mann-Whitney U test, and multivariable logistic regression was used to identify relevant factors associated with cognitive impairment in diabetes patients. Results:Compared to the control group, the dapagliflozin group exhibited significant increases in MMSE and MoCA scores, estimated glomerular filtration rate, and plasma concentration Aβ40(all P<0.05); And the incidence of MCI, homeostasis model assessment for insulin resistance(HOMA-IR), total cholesterol, triglycerides, urine albumin creatine ratio, plasma Aβ42, and Aβ42/Aβ40 ratio were significantly decreased(all P<0.05). Compared with the MCI subgroup, duration of dapagliflozin treatment in the non-MCI subgroup were significantly increased( P<0.05); There were statistically significant decreased in the non-MCI subgroup in age, systolic blood pressure, fasting plasma C-peptide, and HOMA-IR(all P<0.05). Multivariable logistic regression analysis showed that duration of dapagliflozin treatment was a protective factor for cognitive dysfunction( OR=0.322, 95% CI 0.150-0.692, P=0.004) and the age and HOMA-IR were risk factors( OR=1.109, 95% CI 1.014-1.212, P=0.023; OR=3.376, 95% CI 1.276-8.931, P=0.014). Conclusion:Dapagliflozin may improve cognitive function and significantly reduce the incidence of MCI in middle-aged and elderly patients with type 2 diabetes mellitus, possibly associated with the improvement of insulin resistance.
