ABSTRACT
Objective:To explore the effect of intervention model based on comprehensive nutrition management on glucose and lipid metabolism and pregnancy outcome in patients with gestational diabetes mellitus (GDM).Methods:104 GDM patients admitted to Shanxi Bethune Hospital from February 2022 to March 2023 were randomly divided into control group and experimental group, with 52 cases in each group. The control group implemented routine management measures and nutrition guidance, while the experimental group implemented an intervention model based on comprehensive nutrition management on the basis of routine management. The indexes of glucose and lipid metabolism (glycosylated hemoglobin, fasting blood glucose, 2 h postprandial blood glucose, total cholesterol, triglyceride and low density lipoprotein cholesterol), pregnancy outcome, self-management ability and self-efficacy were compared between the two groups before and after intervention.Results:Before the intervention, there was no significant difference in general situation, glucose and lipid metabolism index, self-management ability and self-efficacy between the two groups ( P>0.05). After the intervention, the level of glucose and lipid metabolism index in the experimental group was significantly lower than that in the control group, with statistical significance ( P<0.05). The incidence of adverse pregnancy outcome in the experimental group was significantly lower than that in the control group, with statistical significance ( P<0.05). The scores of self-management ability and self-efficacy in the experimental group were significantly higher than those in the control group, with statistical significance ( P<0.05). Conclusion:The intervention model based on comprehensive nutrition management can effectively improve the glucose and lipid metabolism index and pregnancy outcome of GDM patients, and significantly improve their self-management ability and self-efficacy related to nutrition management, which has high clinical application and promotion value.
ABSTRACT
Objective:The purpose of this study is to explore the clinical characteristics of Coronavirus Disease 2019 (COVID-19) in patients with type 2 diabetes mellitus (T2DM), and analyze the risk factors for adverse outcomes.Methods:2 052 patients diagnosed with COVID-19 who were hospitalized in Shanxi Bethune Hospital between December 1, 2022 and March 20, 2023 were included. They were divided into diabetes group ( n=70) and non-diabetes group ( n=1 982) according to the presence or absence of comorbid T2DM. The two groups were matched at 1:1 via propensity score matching. Clinical characteristics and laboratory examination results of the two groups were compared. According to the outcomes during hospitalization, the two groups were further divided into two subgroups respectively. Univariate analysis and subsequent binary Logistic regression was used to analyze the risk factors of adverse outcomes in patients with COVID-19 and type 2 diabetes. Results:After the propensity score matching, the most common comorbid condition in diabetes group and non-diabetes group was hypertension. The proportion of patients with severe or critical disease in diabetes group was higher compared with non-diabetes group. The levels of hemoglobin A1c (HbA1c), fasting blood glucose (FBG), blood urea, IL-4, IL-6, IL-10, IFN-γ and TNF-α were significantly higher in the diabetes group ( P<0.05). Logistic regression analysis within the diabetes group showed that hypertension ( OR=3.640, 95% CI: 3.156 to 4.290), FBG>11 mmol/L ( OR=3.283, 95% CI: 1.416 to 7.611), HbA1c>10% ( OR=2.718, 95% CI: 1.024 to 7.213) were independent risk factors for adverse outcomes in patients with COVID-19 and type 2 diabetes(all P<0.05). Conclusions:Compared with the non-diabetes group, patients with COVID-19 and T2DM have worse inflammatory response and higher levels of inflammatory cytokines. The elevated levels of FBG and HbA1c are related to the adverse outcome in patients with COVID-19 and T2DM.
ABSTRACT
Objective:To investigate the levels of osteoporosis-related biomarkers in individuals with subclinical hypothyroidism complicated by type 2 diabetes mellitus.Methods:A cross-sectional study. From January 2021 to June 2022, 40 patients with subclinical hypothyroidism, 40 patients with type 2 diabetes, 40 patients with type 2 diabetes complicated with subclinical hypothyroidism, and 40 individuals receiving physical examination in Shanxi Bethune Hospital were selected as subjects in this study. The glucose and lipid metabolism indexes and bone metabolism indexes of the subjects were detected, and the differences and correlations of the metabolic indexes among the groups were analyzed by t-tests, nonparametric tests or correlation analysis. Results:Compared with healthy group, beta C-terminal cross-linked telopeptides of type Ⅰ collagen (β-CTX) level in type 2 diabetes group was higher [(344.60±125.61) vs (227.56±68.33) pg/ml] ( t=-5.176, P<0.001), osteocalcin (OC) and total procollagen type 1 aminoterminal peptide (t-PINP) were both lower [(15.76±4.70) vs (28.02±5.83)ng/ml, (43.49±13.63) vs (59.58±15.80) ng/ml] ( t=10.352, t=4.874, P<0.001). The β-CTX level in type 2 diabetes patients complicated with hypothyroidism was higher than that in patients with simple subclinical hypothyroidism [(380.51±122.22) vs (212.41±44.17) pg/ml] ( t=-8.180 ,P<0.001), but the levels of OC and t-PINP were both lower [(13.67±4.06) vs (26.12±4.55) ng/ml, (38.76±9.53) vs (61.50±12.31) ng/ml] ( t=12.897, P<0.001); but there was no significant difference in the three biomarkers between patients with type 2 diabetes mellitus complicated by subclinical hypothyroidism and those with type 2 diabetes mellitus alone. [β-CTX: (380.51±122.22) vs (344.60±125.61) pg/ml, OC: (13.67±4.06) vs (15.76±4.70) ng/ml, t-PINP: (38.76±9.53) vs (43.49±13.63) ng/ml] ( t=1.296,1.890,-1.799 ,all P>0.05). In the patients with type 2 diabetes mellitus complicated by subclinical hypothyroidism, the β-CTX was positively correlated with fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c)( r=0.293,0.487,all P<0.05), while OC and t-PINP were negatively correlated with FBG and HbA1c ( r=-0.560,-0.502,-0.289,-0.326, P<0.05). Conclusion:Changes of serum osteoporosis-related biomarkers in subclinical hypothyroidism patients with type 2 diabetes indicate the increased risk of osteoporosis in those patients.

ABSTRACT
BackgroundHeterologous orally administered adenovirus type-5 vector-based COVID-19 vaccine (Ad5-nCoV) in individuals who were primed with two-dose CoronaVac (an inactivated SARS-CoV-2 vaccine, by Sinovac) previously, has been reported to be safe and highly immunogenic within 28 days post-boosting. However, antibody persistence and safety up to 6 months of this regimen are not been reported yet. MethodsThis is a randomized, open label, single-center trial on safety and immunogenicity of heterologous boost immunization with an orally administered aerosolised Ad5-nCoV vs. homologous boost immunization with CoronaVac after two-dose priming with CoronaVac in Chinese adults aged 18 years and older (NCT05043259). We followed the participants in this trial, including 140 in the low-dose aerosolised Ad5-nCoV group, 139 in the high-dose aerosolised Ad5-nCoV group, and 140 in the CoronaVac group for 6 months. Neutralising antibodies (NAbs) against live wild-type SARS-CoV-2 virus and omicron variant, and receptor-binding domain (RBD)-specific IgG antibodies were detected in serum samples collected at 28 days, 3 months, and 6 months after the booster dose. Serious adverse events (SAEs) were documented till month 6. ResultsThe low-dose and high-dose heterologous boost immunisation groups had NAb GMTs against live wild-type SARS-CoV-2 of 1937.3 [95% CI 1466.9, 2558.4] and 1350.8 [95% CI 952.6, 1915.3], which were 26.4 folds and 18.4 folds higher than that the CoronaVac group did (73.5 [95% CI 52.3, 103.3]) at 28 days. The low-dose and high-dose heterologous boost immunisation groups had NAb GMTs against live wild-type SARS-CoV-2 of 530.1 (95% CI 412.5, 681.1) and 457.6 (95%CI 349.4, 599.2), which were 26.0 folds and 22.4 folds higher than that the CoronaVac group did (20.4 [95%CI 14.3, 29.1]) at 3 months, respectively. At 6 months, the low-dose and high-dose heterologous booster groups had NAb GMTs against live wild-type SARS-CoV-2 of 312.9 (95% CI 237.7, 411.8) and 251.1 (95% CI 178.2, 354.0), which were 30.1 folds and 24.1 folds higher than the CoronaVac group did (10.4 [95% CI 7.8, 14.0]), respectively. Additionally, the low-dose and high-dose heterologous booster groups had NAb GMTs against live omicron variant of 52.0 (95% CI 37.2, 72.6) and 23.1 (95% CI 15.7, 33.9) at 28 days, 27.9 (95% CI 18.8, 41.3) and 23.3 (95% CI 16.2, 33.3) at 3 months, 16.0 (95% CI 10.9, 23.5) and 12.0 (95% CI 8.5, 16.8) at 6 months, respectively. However, nearly all participants had no detectable NAbs for omicron variant in the CoronaVac group at either 28 days, 3 months, or 6 months. No vaccine-related SAEs were observed. ConclusionsThese data suggested that heterologous aerosolised Ad5-nCoV following two-dose CoronaVac priming was safe and persistently more immunogenic than three-dose CoronaVac, although immune responses waned over time.
ABSTRACT
Objective:To explore the effects of different blood glucose management modes on self-management ability and glucose and lipid metabolism in patients with type 2 diabetes mellitus (T2DM) based on the WeChat platform.Methods:240 patients with T2DM were selected in Taiyuan Central Hospital from January to June 2020 for the study. They were randomly divided into general management groups, medical care management groups, peer management groups, and medical care and peer co-management groups using random number table, with 60 cases in each group. The general management group received routine outpatient follow-up. The medical care management group, peer management group, and medical care and peer management group established WeChat groups for management, respectively. Each group′s self-management ability and glucose and lipid metabolism indexes were compared before and after six months of intervention. t-test or nonparametric tests were used to compare. Results:After the intervention, self-management abilities such as diet, exercise, blood glucose monitoring, medication compliance, foot care, smoking and fasting blood glucose (FBG), and glycosylated hemoglobin (HbA 1c) were improved in the four groups (all P<0.05). The medical care management, peer management, and medical care and peer co-management groups were further improved than the general group (all P<0.05). Except for smoking, the above medical care and peer co-management group indicators were statistically different from those of the separate medical care management and peer management group (all P<0.05). Triacylglycerol (TG) of the four groups were improved compared with the previous [1.9(1.2, 2.7) compared with 2.3(1.6, 3.5)mmol/L, 1.4(1.2, 2.1) compared with 2.2(1.6, 3.2)mmol/L, 1.6(1.1, 2.0) compared with 2.2(1.4, 3.2)mmol/L, 1.5(1.0, 2.1) compared with 2.4(1.3, 3.1)mmol/L] (all P<0.05), and after the intervention, the total cholesterol (TC) of the four groups was also improved compared with that before the intervention [(4.7±0.9) compared with (5.1±1.2)mmol/L, (4.2±1.1) compared with (5.2±1.2)mmol/L, (4.3±1.1) compared with (5.4±1.3)mmol/L, (4.2±1.1) compared with (5.0±1.4)mmol/L] (all P<0.05), and TG and TC of the medical care management, peer management, and medical care and peer co-management groups were lower than those of the general group (all P<0.05). Conclusion:Based on the WeChat platform, the management mode of medical care and peer co-management is conducive to T2DM patients′ better self-management and blood glucose control.
ABSTRACT
Purpose@#Lymphoblastic lymphoma (LBL) is an invasive neoplasm of precursor T-cell or B-cell lineage.A broadly accepted standard treatment for adult LBL has not yet been defined. @*Materials and Methods@#To address this issue, we compared two chemotherapy regimens: a modified non-Hodgkinlymphoma Berlin–Frankfurt–Mu!nster-95 (NHL-BFM-95) regimen and HyperCVAD/MA. Thisretrospective study consecutively enrolled 207 adult LBL patients at two hospitals from2000 to 2018. Univariate and multivariate analysis were used to assess prognostic factors. @*Results@#In the present study, most clinical characteristics were similar between the two treatmentgroups except for age and lactate dehydrogenase (LDH) level. Patients treated with modifiedNHL-BFM-95 regimen tended to be younger and with elevated LDH level. The modified NHLBFM-95 regimen produced better treatment outcomes than those with HyperCVAD/MA inpatients with T-LBL or patients < 40 years. Treatment with HyperCVAD/MA, high EasternCooperative Oncology Group scores, and bone marrow involvement were independent riskfactors in T-LBL. No patients interrupted treatment for severe adverse events. @*Conclusion@#The results suggested that the modified regimen is well-tolerated and can produce the promisingoutcomes in patients with T-LBL or patients < 40 years.
ABSTRACT
Objective:To investigate the safety and feasibility of endoscopic cholecystolithotomy after endoscopic ultrasonography (EUS)-guided lumen-apposing metal stent (LAMS) implantation in animals.Methods:Six miniature pigs of 30-35 kg were selected to laparotomy under intravenous anesthesia. Two to four sterile human stones with diameter of 0.8-2.0 cm were implanted in their gallbladder. After successful modeling, LAMS was implanted between the stomach and gallbladder under the guidance of EUS. Ultrafine endoscope was used to search and remove stones after passing the gastric stent into the gallbladder. Endoscopic sphincterotomy (EST) and endoscopic retrograde biliary drainage (ERBD) was performed to prevent bile leakage. And then ordinary endoscope was used to remove LAMS and close the wound. The success rate, operation time, and incidence of complications were analyzed.Results:Five pigs were successfully implanted with LAMS, and the ultrafine endoscope entered the gallbladder smoothly. Small stones were removed from the stone basket, and large stones were completely removed after laser lithotripsy. The total operation time was 87-128 min. No postoperative complications such as bleeding, perforation, infection, or biliary fistula were observed. Failure in 1 pig was due to the first EST plus ERBD, resulting in rapid reduction of gallbladder volume and away from the gastric cavity leading to puncture difficulties.Conclusion:Endoscopic cholecystolithotomy after EUS-guided LAMS implantation is safe and feasible, and may provide animal experimental evidence for potential therapeutic approach for patients with difficulty in cholecystectomy.
ABSTRACT
Objective To investigate the predictive value of early measurement of serum inflammatory mediators for infectious pancreatic necrosis secondary to severe acute pancreatitis (SAP).Methods A retrospective analysis was performed for the clinical data of 166 patients who were admitted to our hospital from January 2012 to January 2017.According to the presence or absence of secondary infectious pancreatic necrosis,the patients were divided into infection group with 58 patients and non-infection group with 108 patients.The serum levels of inflammatory factors were compared between the two groups.The receiver operating characteristic (ROC) curve was used for the analysis of indices with statistical significance.The independent samples t-test was used for comparison of continuous data between groups,and the chi -square test was used for comparison of categorical data between groups.Results Of all 166 SAP patients,58 experienced secondary infectious pancreatic necrosis,resulting in an incidence rate of 34.9％.Compared with the non-infection group,the infection group had significantly higher serum lipase,procalcitonin (PCT),C-reactive protein (CRP),and APACHE Ⅱ score (t =8.679,20.416,18.429,and 8.563,all P ＜0.05).The ROC curve analysis showed that serum lipase,PCT,CRP,and APACHE Ⅱ score had areas under the ROC curve of 0.647,0.877,0.823,and 0.655,respectively,with cut-off values of 612.5 U/L,7.5 ng/ml,226.5 mg/L,and 16.5 points,sensitivities of 68.5％,91.2％,86.8％,and 60.5％,and specificities of 59.3％,83.6％,80.1％,and 68.7％,respectively.Conclusion The abnormally elevated serum levels of CRP and PCT have a certain predictive value for infectious pancreatic necrosis secondary to SAP with convenient and fast operation,and therefore,it holds promise for clinical application.
ABSTRACT
Objective Preoperative autologous blood donation(PABD) can reduce the demand of allogeneic blood transfusion and its safety in obstetrical application has been proved.The article aimed to explore the effects of PABD on reducing allogeneic blood transfusion in pregnant women with placenta previa and the optimal PABD volume for implanted placenta.Methods Retrospective analysis were made on 156 cases with placenta previa hospitalized in our hospital from January 2015 to April 2016, including 78 cases with placenta implantation.According to the volume of PABD, the cases were classified into no PABD group, 300~400mL PABD group, and 600ml PABD group.Data of postpartum hemorrhage volume and allogeneic blood transfusion after delivery were collected to analyze the effectiveness of PABD in reducing the need for allogeneic blood transfusion during pregnancy.Results The hemorrhage volume during the delivery of all 156 patients with placenta previa was 230-5670mL (median 985ml), the rate of severe postpartum hemorrhage (PPH) was 49.4% (77/156), and the rate of allogeneic blood transfusion was 33.3% (52/156).In patients who had no PABD, the rate of allogeneic blood transfusion was 48.2% (40/83).However, this rate dropped down to 16.4% in PABD patients (12/73)(χ2=17.624,P<0.001).The rate of allogeneic blood transfusion in patients was different according to the situation of placenta planting, 43.3% in patients with no placenta plantingand 53.8% in patients with placenta planting.600ml autologous blood could meet all the needs for blood transfusion if there was no placenta implantation.300-400mL PABD could meet the needs of more than 80% patients.11.2%-13.3% of ABD patients might need allogeneic blood transfusion in addition to autologous blood.However, the amount of allogeneic RBC and FFP per capita reduced.Conclusion Patients with placenta previa is in high risk of PPH and PABD can improve their medical safety by reducing the rate and volume of the allogeneic blood transfusion.The strategy of 300-400mL PABD during pregnancy are recommended if there is no contraindication.
ABSTRACT
Cervical cancer is one of the most common gynecologic malignancy,ranking fourth in new cases and deaths in 2012.High-risk early stage cervical cancer after operative need adjuvant treatment.Compared with postoperative radiotherapy alone,CCRT can reduce the pelvic recurrence rates and improve survival rates. And CCRT can extend median survival time and survival rates than sequential CRT after operative. CCRT plus consolidation chemotherapy may play a potential role in further improving survival outcomes for high-risk early stage cervical cancer patients compared with CCRT alone. Retrospective studies show that CCRT had equivalent effects with postoperative chemotherapy alone,but further research is needed. Factors influencing the efficacy of postoperative CCRT include chemotherapy regimens,radiotherapy technology,the interval time between surgery and CCRT,multiple pelvic lymph node metastasis and number of pelvic lymph node dissection. Toxicities mainly include hematologic and gastrointestinal toxicity. Hematologic toxicity is the most common. The incidence of toxicity can be reduced by improving radiotherapy techniques.
ABSTRACT
Background Small incision lenticule extraction (SMILE) is lack of eye-tracking system and there is controversy in the treatment of astigmatism.It is very important to understand its correction effctiveness for myopic astigmatism.Objective This study was to evaluate the clinical outcomes in the correction of myopic astigmatism between SMILE and femtosecond laser assisted laser in situ keratomileusis (FS-LASIK).Methods In this retrospective study,95 eyes of 51 patients and 69 eyes of 40 patients with myopic astigmatism underwent the SMILE surgery and FS-LASIK surgery respectively in Tianjin Eye Hospital from December 2013 to July 2014 under the informed consent.No significant differences were found in spherical power,astigmatic power and spherical equivalent (SE) between the SMILE group and FS-LASIK group before surgery (all at P＞0.05).The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),manifest refraction,slit-lamp microscopy,intraocular pressure and corneal topography were measured before surgery and 1 day,1 week,1 month,3 months after surgery.Vector analysis was used to calculate the components of astigmatism before and after surgery.Correction index (CI),index of success (IOS),angle of error (AofE) and flattening index (FI) were used to evaluate the correction effectiveness of astigmatism.Safety index and efficacy index were used to evaluate the recovery status of visual acuity.The corrected effectiveness was compared between the two groups,and the correlations of kappa angle with measured parameter were assessed by Spearman rank correlation analysis.Results The mean spherical power,astigmatic power and SE were (0.003±0.106),(-0.063 ± 0.126) and (-0.029 ± 0.101) D in the SMILE group,which were significantly lower than (0.112 ± 0.212),(-0.091 ± 0.142) and (0.067 ± 0.198)D in the FS-LASIK group (Z =-4.328,-3.197,both at P＜0.05).Vector analysis showed the postoperative with-the-rule astigmatism in the SMILE group and oblique astigmatism in the FS-LASIK group respectively,and the CI and F1 in the SMILE group were significantly lower than those in the FS-LASIK group (Z =-3.051,-3.126,both at P ＜ 0.05).The insignificant reduce in IOS and AofE were seen in the SMILE group compared with the FS-LASIK group (Z=-1.557,P=0.119;Z =-1.923,P =0.054).In addition,the safety index and efficacy index were not significantly different between the two groups (both at P ＞ 0.05).Negative correlations were found between safety index or efficacy index and preoperative kappa angle in the SMILE group (r =-0.258,-0.257,both at P＜0.05).Conclusions Both SMILE and FS-LASIK surgeries are effective and safe in correcting myopic astigmatism with good postoperative visual acuity.SMILE surgery shows less axis rotation and higher accuracy than FS-LASIK because of small incision and flapless procedure.The correction of cylinder can adjust based on experience of surgeon.
ABSTRACT
Background The use of adaptive optics (AO) system in ophthalmic clinic and basic studies has increased in recent years.However,there are few reports on the stability of ocular aberrations after correction.Objective This study was to analyze the stability of aberration after correction by observing the repeatability of ocular aberration measurements.Methods Forty-one postgraduate school students and volunteers who meet the conditions were included from February to April 2014.The Zernike aberration coefficients including astigmatism (Z2-2,Z22),defocus (Z02),trefoil (Z33,Z3-3),coma (Z3-1,Z13),spherical aberration (Z40) and the value of root mean square (RMS) including 3rd-order to 7th-order aberrations,total higher-order aberrations (HOAs) and total ocular aberrations (TOAs) were measured by using AO system.The repeatability and stability of these data after corrected with AO system were analyzed.The repeatability was evaluated by ANOVA,within-subject standard deviation (Sw),repeatability (r) and intra-class correlation coefficients (ICC).The stability was evaluated by the nonparametric Friedman's rank test.Results AO system showed excellent repeatability on Z2-2,Z22,Z20 and TOA RMS (ICC＞ 0.9),good repeatability on Z13,Z33,Z3-3,Z40,3rd-order RMS,4th-order RMS,HOA RMS (ICC ＞ 0.75),poor repeatability on Z3-1,5th-order RMS,6th-order RMS,7th-order RMS (ICC ＜ 0.75).Repeatability (2.77 Sw) values ranged from 0.009 mm (7th-order RMS) to 0.163 mm (Z31).After low-order ocular aberrations were corrected,It was founded that Z2-2,Z22 reached stable state at the 4th second;Z02 was stable at the 6th second;Z3-3 and Z33 reached stable state at the 4th second and third second,separately;Z13 was stable from 3rd-second to 9th-second,Z3-1 was stable at the 4th-second.Z40 and HOA RMS were stable at the third second and fifth second,respectively.The Z2-2,Z02,Z22,Z3-3,Z3-1,Z33,Z40 and HOA RMS were significantly different among different time points before and after low-order aberrations correction (all at P ＜ 0.05).Z2-2,Z22,Z20 reached stable state at the 4th-second,3rd-second and 5th-second,respectively;Z3-3,Z33 reached stable state at the 2nd-second and 3rd-second,respectively;Z3-1and Z40 reached stable state at the 2nd-second;HOA RMS reached stable state at the 5th-second.Conclusions After correcting the human ocular aberration,different aberrations can reach stable state at different time.The time of Z02,Z22,Z3-3,Z3-1,Z40reaching stable state after 2nd-order to 5th-order ocular aberrations correction was earlier than those of lower-order aberrations correction.

Objective To explore the relationship between childhood asthma and pregnant and neonatal risk factors, thus provide evidence for early prevention of childhood asthma. Methods 162 children diagnosed asthma and 213 healthy children in pediatric outpatient and the inpatient services of our hospital who was born and living in Baotou city were retrospectively analyzed. The pregnancy related factors (parity, fever during pregnancy, pregnancy-induced hypertension syndrome, gestational diabetes mellitus, history of overdose in early-pregnancy) and the neonatal period related factors (surface defects, asphyxia, rough placenta, birth weight, number of fetus during this pregnancy, gestational age, premature birth, cesarean section) were investigated. The sex and age showed no signiifcance between childhood asthma and control group. Results Eight pregnant and neonatal factors (fever during pregnancy, pregnancy-induced hypertension syndrome, history of overdose in early-pregnancy, surface defects, asphyxia, rough placenta, birth weight, premature birth, cesarean section) showed signiifcant difference between the two groups (P<0.05). Multifactor regression analysis found fever during pregnancy (OR=9.43, 95%CI:3.08~28.82), rough placenta (OR=2.15, 95%CI:1.29~3.59), premature birth (OR=5.16, 95%CI:1.53~17.39) and cesarean section (OR=4.05, 95%CI:2.40~6.86)are independent risk factors for childhood asthma. Conclusions Fever during pregnancy, abnormal placenta;premature birth and cesarean section are likely risk factors of childhood asthma.
ABSTRACT
Objective To assess the relationship between serum vitamin D and autoimmune thyroid disease.Methods Subjects included total 520 persons receiving regular health examination,and serum calcium,phosphorus,parathyroid hormone (PTH),thyroid peroxidase autoantibody (TPOAb) and 25-dihydroxy vitamin Ds was measured.The incidence of 25-dihydroxy vitamin D3 deficiency (≤30 μ g/L)was observed.The relationship between 25-dihydroxy vitamin D3 deficiency and autoimmune thyroid disease was analyzed.Results The serum 25-dihydroxy vitamin D3 of all the subjects was (24.47 ± 7.21) μ g/L,and the incidence of 25-dihydroxy vitamin D3 deficiency (≤30 μg/L) was 61.15％ (318/520),and the positive rate of TPOAb was 21.54％ (112/520).The proportion of TPOAb ＞ 50 kU/L or ＞ 100 kU/L in subjects with 25-dihydroxy vitamin D3≤30 μ g/L was higher than that in subjects with 25-dihydroxy vitamin D3 ＞ 30 μg/L [25.79％(82/318) vs.19.80％(40/202) and 9.43％(30/318) vs.4.46％(9/202)],and there was significant difference (P ＜ 0.05).The relationship between 25-dihydroxy vitamin D3 and TPOAb was assessed and showed significant inverse correlation (r =-0.13,P ＜0.05).Conclusions Vitamin D deficiency is very common in the population,and autoimmune thyroid disease is related with vitamin D deficiency,which may has impact on the body's immune regulation.Specific mechanism and whether vitamin D supplementation can intervene and treat autoimmune thyroid disease need further study.
ABSTRACT
A method to prepare granular palygorskite (GPA) was put forward in this research, and its potential use to remove phosphate species from aqueous solution was assessed. Batch experiments were performed to study the adsorption equilibrium and influence of contact time and pH on the adsorption and desorption of phosphate onto GPA in water. The maximum phosphate adsorption capacity of GPA was 13.1 mg/g. Kinetic data revealed that more than 90% of phosphate was adsorbed onto GPA within 2 hours. Phosphate adsorption capacity was 0.10 mg/g in column experiments, and co-existing anions could decrease phosphate removal. The saturated column was regenerated by 0.2 mol/L sodium hydroxide, and the GPA could be reused in phosphate removal. The data obtained from both batch and column studies indicated that GPA could be used effectively to remove phosphate from water.
