This study was aimed to establish an inspection method for the limited quantity of aconitine and the content determination of schisandrol in Yi-Shen Xiao-Zhong(YSXZ) pill.Thin layer chromatography (TLC) was used to inspect the limited quantity of aconitine in YSXZ pill.The content of schisandrol was determined by high-performance liquid chromatography (HPLC).The results showed that the identification method of the limited quantity of aconitine and the content determination method of schisandrol were established.Compared to the correspondent position of the control chromatography,the limited quantity of aconitine was 2.5μg,which was much lower than the dose of inducing toxic reaction.It can be used in the limited quantity control of aconitine for toxic reaction in YSXZ pill.The calibration curve of schisandrol was linear at 2.92-95.36μg·mL-1.The regression equation wasy = 18.630x + 2.556 (r = 1).The average recovery was 95.10% and RSD was 1.55% (n = 6).It was concluded that the established method for the inspection and content determination of aconitine and schisandrol was simple,accurate and reproducible.It can be used in the quality control of YSXZ pill.

objective To explore the correlation of single nucleotide polymorphism (SNP) frequency of adiponectin(APN)in patients with type Ⅱ diabetes(T2DM)and its complications,investigate whether the SNP is a risk factor of inheritance of T2DM,and to set up a highly efficient.accurate, economical and practical screening assay to detect the mutation of APN in clinical practice.Methods According to the diagnostic criteria of T2DM,patients with coronary heart disease(CHD),hypertension (HP),and diabetic nephropathy(NE)were recruited into this study.In simple,12DM group,T2DM-HP, T2DM-CHD.T2DM-NE and the control group.serum biochemistry items are measured.The technique of denaturing high-performance liquid chromatography(DHPLC)was used to detect SNPs of ANP gene.Results After all fragments amplified in the reglen of promoter of APN gene were compared with APN GeneID:9370 sequence recorded in GenBank,point mutation has been identified(-11377G/C).The frequency of genotypes of GG,GC,and CC are 5.16%,42.25%,52.58%and 3.4%.32.75%,63.85%,respectively in the groups of T2DM and control.The frequency of G allele was related to the incidence of T2DM,and is a risk factor of T2DM.The relative risk of GC to CC in developing T2DM is much high than that in the control group (OR=0.55).By comparing the clinical data of different groups of genotype in T2DM,it was observed that the genotype affected systolic blood pressure,BMI,abdominal circumference, and waist-buttock ratio(P=0.015).After optimizing the experimental conditions.it was found column temperature 6 0℃ was the best when using DHPLC technology to estimate SNP of APN gene.Conclusion SNP (-11377G/C) of APN gene G allele has a definite correlation with complications of hypertension in T2DM patients,and may contribute to the genetic risk for type 2 diabetes.

Objective To investigate the relationship between CRP, plasminogen activator inhibitor type 1 (PAI-1) levels, PAI-1 gene promoter 4G/5G polymorphism and the type of acute myocardial infarction (ST elevation myocardial infarction, STEMI vs the non-ST elevation Myocardial infarction, NSTEMI). Methods One hundred seventy-six consecutive patients with AMI were included for the study, of whom 60 had STEMI and 56 had NSTEMI, and 60 adults without cardiovascular and cerebrovascular disease were selected as controls. Blood samples were obtained from patients within 6 h of AMI and the plasma PAI-1, CRP, and the gene polymorphism were measured. Results Plasma levels of PAI-1 and CRP were higher in AMI groups, compared those in the control group, and plasma levels of PAI-1 were significantly higher in patients with STEMI compared to those with NSTEMI (80.12ng/ml VS.73.01ng/ml, P <0.01), while CRP levels were not significantly different between patient with STEMI and NSTEMI (3.87±0.79 mg/ml VS.4.01±0.69mg/ml, P>0.05). PAI-1 levels presented a significant correlation with CRP levels in the NSTEMI subjects. However, PAI-1 and CRP levels could explain the lack of a significant relationship between them in control and STEMI subjects.The frequencies of 4G/4G genotype in the AMI group were higher than those in the control group and higher in patient with STEMI than in patient with NSTEMI. Plasma levels of PAI-1 in subjects with 4G/4G genotype were significantly increased as compared to those in subjects with 4G/5G and 5G/5G genotype. Conclusions Plasma PAI-1 levels were associated with different myocardial infarction type, and PAI-1 promoter 4G/5G polymorphisms and CRP may be related to plasma PAI-1 levels.

Objective To determine the optimal dose of oxycodone for patient-controlled intravenous analgesia (PCIA) after gastrointestinal surgery when combined with dexmedetomidine in elderly patients.Methods Sixty patients of both sexes,aged 65-80 yr,weighing 50-75 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,undergoing elective open gastrointestinal surgery,were divided into 3 different doses of oxycodone groups (group O1,group O2 and group O3,n=20 each) using a random number table.At 15 min before the end of surgery,oxycodone 0.1 mg/kg was intravenously injected,and PCIA pump was connected simultaneously.In O1,O2 and O3 groups,the PCIA solution contained dexmedetomidine 2.0 μg/kg and oxycodone 0.3,0.5 and 0.7 mg/kg in 100 ml of 0.9％ normal saline,respectively.The PCIA pump was set up to deliver a 0.5 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Oxycodone 0.05 mg/kg was intravenously injected as a rescue analgesic after surgery,postoperative pain was assessed using a verbal rating scale,and the verbal rating scale score was maintained ≤4.The number of successfully delivered doses and requirement for rescue analgesics were recorded within 48 h after surgery,and the rate of rescue analgesia was calculated.The occurrence of adverse reactions such as nausea,vomiting,dizziness,respiratory depression,somnolence,bradycardia,hypotension and over-sedation was recorded.Patients' satisfaction with analgesia at postoperative 72 h and the length of postoperative hospital stay were also recorded.Results Compared with group O1,the rate of rescue analgesia after surgery and the number of successfully delivered doses were significantly decreased,and the degree of patients' satisfaction with analgesia was increased in O2 and O3 groups,and the incidence of nausea and somnolence was significantly increased in group O3 (P＜0.05).Compared with group O2,no significant change was found in the rate of rescue analgesia after surgery or the number of successfully delivered doses (P＞0.05),and the incidence of nausea and somnolence was increased in group O3 (P＜0.05).Conclusion When combined with dexmedetomidine 2.0 μg/kg,the optimal dose of oxycodone for PCIA is 0.5 mg/kg after gastrointestinal surgery in elderly patients.

Objective:To learn about the status of thyroid function and intelligence quotient (IQ) of children in areas with different iodine nutrition levels in Xinjiang Uygur Autonomous Region, and to explore the health risk of children with median urinary iodine of 200 - 299 μg/L, and to provide a basis for scientific iodine supplementation.Methods:In May 2019, in Xinjiang Uygur Autonomous Region, Altay Prefecture and Kashgar Prefecture were selected, where the median urinary iodine of children aged 8 to 10 years were 100 - 199 and 200 - 299 μg/L for three consecutive years (2017 - 2019). A stratified random sampling method was used to select 400 children aged 8 to 10 years in each of the two regions, urine and blood samples were collected to detect urinary iodine and thyroid function [thyrotropin stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), anti-thyroglobulin antibody (TgAb), and anti-thyroperoxidase antibody (TPOAb)]. At the same time, children's IQ was measured and determined by Second Revision of Combined Raven's Test (CRT-C2) in China and Second Revision of Combined Raven's Test for Children-the Rural, in China (CRT-RC2). Results:The median urinary iodine of children aged 8 to 10 years in Altay Prefecture and Kashgar Prefecture was 188.6 and 250.1 μg/L, respectively. There was no statistically significant difference in thyroid function indexes TSH and FT 3 levels between the two regions ( Z = - 0.58, t = 0.49, P > 0.05), while there was statistically significant difference in FT 4 level ( t = 60.08, P < 0.001). There was no statistically significant difference in TgAb positive rate [3.6% (14/394), 4.0% (16/399)] between the two regions (χ 2 = 0.11, P = 0.736), but the difference of TPOAb positive rate [9.6% (38/394), 30.6% (122/399)] was statistically significant (χ 2 = 53.93, P < 0.001), while the difference of dual antibody positive rate [0.8% (3/394), 2.0% (8/399)] was not statistically significant ( P = 0.134). There was no statistically significant difference in the detection rates of subclinical hypothyroidism [8.9% (35/394), 11.0% (44/399)], subclinical hyperthyroidism [1.0% (4/394), 1.3% (5/399)] and hyperthyroidism [0.3% (1/394), 0.8% (3/399)] in children between the two regions ( P > 0.05). The IQ results of children in the two regions were 96.55 ± 11.36 and 89.57 ± 12.35, respectively, and there was no significant difference between them ( t = 2.79, P = 0.095). Conclusions:The thyroid function status of children is similar in the two regions with median urinary iodine of 100 - 199 μg/L and 200 - 299 μg/L in children aged 8 to 10 years, but the TPOAb positive rate is significantly different. Children whose iodine nutritional level is at or above the appropriate level have no obvious changes in intelligence. It is suggested that median urinary iodine at 200 - 299 μg/L is a relatively safe iodine nutrition state.
