Purpose To investigate the adverse reactions and management in the process of transvaginal real-time three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy).Materials and Methods A total of 976 patients with infertility accepting 3D-HyCoSy in Jiangsu Provincial Hospital of Traditional Chinese Medicine,Affiliated Hospital of Nanjing University of Traditional Chinese Medicine,from December 2014 to August 2016 were retrospectively analyzed.The pain degree was evaluated using visual analog scale (VAS).Adverse reactions,including contrast countercurrent,vomiting,syncope and allergies,were recorded.The relationship between adverse reactions and ultrasound imaging signs was explored.Results There were 66 cases (6.76％) of VAS grade 0,346 cases of mild pain (35.45％),374 cases of moderate pain (38.32％) and 190 cases (19.47％) of severe pain.With the increase in the degree of tubal obstruction,the degree of pain gradually increased.Pain was the most common adverse reaction among patients,followed by vomiting (15 cases,1.54％),syncope (1 case,0.10％),and allergies (1 case,0.10％).The incidence of contrast countercurrent was 12.30％ (120 cases).The adverse reaction incidence of patients with abnormal ultrasound imaging signs was significantly higher than that of patients with normal signs (x2=29.02,P＜0.01).Conclusion With the extensive use of 3D-HyCoSy examination,its clinical application value has attracted a lot of attention,meanwhile,the understanding of its safety and related adverse reactions should also be improved.The state of patients should be closely observed before,during and after 3D-HyCoSy.Medical personnel should watch out for syncope and allergic reactions,and prepare for emergency management.

OBJECTIVE:To evaluate the improvement and rectification effects about prescription checking and intervention skills of pharmacists. METHODS:By retrospective investigation,2417 outpatient prescriptions and 1698 outpatient prescriptions were respectively selected from some one hospital during Oct.-Dec. 2015 (before improvement and rectification) and Jan.-Mar. 2016 (after improvement and rectification). According to standards,guidelines and references as Prescription Administrative Poli-cy,Prescription Review Management Standard(trial)and drug instructions,irrational drug use and prescription checking and inter-vention skills of pharmacists were compared before and after the implementation of rectification measures as optimizing hospital in-formation system,improving comprehensive skills of pharmacists,strengthening pharmacists'concept,establishing feedback mech-anism. RESULTS:After the implementation of rectification measures,unsuitable indications,clinical diagnosis inconsistent with medication,antibiotics use without indications,unsuitable usage and dosage,unsuitable drug combination and irrational drug use were all decreased,but repeated drug use was increased,without statistical significance (P>0.05). The number of non-standard prescriptions and unsuitable prescriptions checked by pharmacists were decreased,without statistical significance(P>0.05). The in-cidence of checking missing,excessive checking and checking error were all increased from 2.40%,0.99%,3.39% before im-provement and rectification to 0.47%,0.29%,0.77%,with statistical significance(P<0.05). CONCLUSIONS:The improvement and rectification measures of the hospital can improve comprehensive prescription checking and intervention skills of pharmacists. Ir-rational drug use should be further standardized.

Objective To identify the clinical features and risk factors of early rheumatoid arthritis (RA)-associated osteoporosis in premenopausal women. Methods A total of 76 premenopausal women with early RA were randomly selected in the Department of Kidney and Rheumatology in the hospital. A total of 84 health cases were randomly selected in our hospital as controls. Bone mineral density (BMD) was determined using dual energy X-ray absorptiometry (DEX). Bone metabolism (CTX, PINP) and inflammatory cytokines (IL-17, IL-6, TNF-α) were examined with quantitative enzyme-linked immune-sorbent assay (ELISA). Quantitative data were expressed as x ±s deviation and the data were compared between groups using non- parametric test (Z value). Multi-group comparison was performed with variance analysis. Qualitative data were compared with Fisher's test. Logistic regression was used to investigate the risk factors. Results ①Compared with the control group, BMD in the premenopausal women with early RA group [neck: (0.802 ±0.193) g/cm2, GT zone: (0.923±0.033) g/cm2, L1: (0.862±0.011) g/cm2] was significantly decreased [(0.981±0.032) g/cm2, (0.771 ±0.023) g/cm2, (0.912 ±0.012) g/cm2, F=14.401, 19.860, 6.560, respectively, both P<0.05). The prevalence of osteoporosis in this group was 7%(5/76), which was higher than controls 1%(1/84). ② According to values of Bone meta-bolism [(CTX: (0.37±0.21) ng/ml] and inflammatory cytokines, TNF-α: (9.8±4.1) pg/ml, IL-6: (33.6±5.7) pg/ml and IL-17: (129±24) pg/ml were markedly increased in premenopausal women in early RA group [(0.24 ±0.09) ng/ml, (6.7 ±1.9) pg/ml, (1.5 ±0.4) pg/ml, (45 ±7) pg/ml, Z=2.722, 5.932, 7.501, 4.370, respectively, both P<0.05]. ③ The premenopausal women with early RA group with osteoporosis were signifi- cantly difference with controls in BMI [(9±3) kg/m2 vs (16±3) kg/m2], bone density of neck [(0.85±0.20) ng/ml vs (0.88±0.14) g/cm2], L2 [(0.75±0.23) g/cm2 vs (0.88±0.14) g/cm2], L3 [(0.87±0.07) g/cm2 vs (0.93±0.14) g/cm2], L4 [(0.92±0.12) g/cm2 vs (0.94±0.16) g/cm2], serum ESR [47.8(22.0, 76.0) mm/1 h vs 18.8(8.7, 35.2) mm/1 h] and DAS28-CRP (5.3 ±1.2 vs 3.8 ±1.2) F=0.68, 14.632, 26.114, 20.931, 36.582, Z=3.21, 6.58, respectively, both P<0.05. ④ Logistic regression showed that IL-6 (Wald χ2=5.78, P=0.021), PINP (Wald χ2=5.12, P=0.031), CTX (Wald χ2=9.17, P=0.003), ESR (Wald χ2=9.24, P=0.011), DAS28-CRP (Wald χ2=17.28, P=0.001) were significantly positively correlated with osteoporosis. Moreover, ordered unconditional Logistic regression analysis of the variables (IL-6, PINP, CTX, ESR, DSA28) described above showed that DAS 28-CRP score [OR=1.58, 95%CI: (1.10, 2.20)] was the most important risk factor for osteoporosis in premenopausal women with early RA. Conclusion The incidence of osteoporosis is high in premenopausal women with early RA than healthy cases. DAS 28-CRP score is the important risk factor for premenopausal women with early RA- associated osteoporosis. Measures relieve symptoms of RA can help to prevent and treatment osteoporosis.

Objective To study the sodium channel α1-subunit (SCN1A) gene in a pair of monozygotic twins with borderland severe myoclonic epilepsy in infancy (SMEB) and its characteristic of clinical manifestations. Methods The clinical features of 2 monozygotic twins were summarized. All 26 exons of SCNIA genes were screened with denaturing high performance liquid chromatography (DHPLC), and direct sequence analysis was performed on those with abnormal elution peak. Results The proband and her sister showed typical clinical features of SMEB. The same heterozygous mutations on exon 26 which caused the related amino acid change were found among them (c. 5348C > T, A1783E). Conclusion Monozygotic twins with similar clinical phenotype of SMEB have same SCN1A gene mutation.

Objective To study the SCN1A gene in a family with partial epilepsy with febrile seizures plus ( PEFS+ ) and its characteristics of inheritance. Methods The clinical features of the 2 patients and their father were summarized. All 26 exons of SCN1A gene were screened with denaturing high performance liquid chromatography (DHPLC), and direct sequence analysis was pedormed on those with abnormal elution peak. Pyrosequencing was subsequently performed in those without abnormality in direct sequence analysis. Results The proband and his sister had the phenotype of PEFS+ . The same heterozygous mutations (AS768G) on exon 26 which caused the related amino acid change (Q1923R) were found among them. Their father had frequent febrile seizures (FS) in childhood, and seizures stopped spontaneously. No abnormality was found in direct sequence but mosaic mutation in the same site was discovered with pyrosequencing (mutation quantity was 25% ). Conclusions The mutatin of SCN1A could cause partial epilepsy. PEFS+ could be inherited, the relatives carrying the affected gene may have mild clinical symptoms, possibly resulting from the low concentration of the mutated gene due to mosaic mutation.

Objectives To investigate the occipital cortex metabolite alterations in repetitive and severe neonatal hypoglycemia rats treated with sodium pyruvate and to reveal the protective role of sodium pyruvate using high resolution 1H nuclear magnetic resonance spectroscopy.Methods Thirty-six 2-dayold Sprague-Dawley rats were randomly divided into hypoglycemia group and pyruvate group with 18 rats in each group.Rats in both groups received intraperitoneal injections of insulin (40 U/kg body weight) at 2,4 and 6 days of age to induce severe hypoglycemia (blood glucose value ≤ 1.4 mmol/L).In the hypoglycemia group,2.5 hours after insulin injection,intraperitoneal injection of 50％ glucose (2 ml/kg) was administered to terminate hypoglycemia,while in the pyruvate group,50％ glucose (2 ml/kg) and sodium pyruvate solution 2.5 ml/kg (500 mg/kg) were injected.Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay was used to observe the status of injured neurons in six neonatal rats,and metabolite changes in occipital cortex of the other 12 rats were detected by 1H nuclear magnetic resonance spectroscopy.The difference between the two groups was compared by independent-samples t test.Results Neonatal rats of both groups reached severe hypoglycemia level 2.5 hours after insulin injection.Compared with hypoglycemia group,pyruvate group had fewer injured neurons (45±5 vs 113 ± 12,t=0.782,P=0.013) and lower injured index in the occipital cortex (0.15 ± 0.03 vs 0.36 ± 0.06,t=l.143,P=0.020).Pyruvate group showed significant decreases in the concentration of taurine [(13.31 ± 2.06) vs (18.44 ± 3.86) mol/kg,t=8.231],glutamine[(1.50 ± 0.24) vs (2.02 ± 0.40) mol/kg,t=3.137],glutamate[(7.04 ± 0.95) vs (9.40 ± 1.73) mol/kg,t=6.449],aspartate[(1.51 ± 0.28) vs (2.15 ± 0.58) mol/kg,t=2.561] and creatine [(6.37±0.99) vs (8.46± 1.77) mol/kg,t =4.226] in the occipital cortex (all P'＜0.017).Conclusions Simultaneous use of glucose and sodium pyruvate to terminate hypoglycemia in repetitive and severe neonatal hypoglycemia rats can effectively alleviate severe hypoglycemia-induced occipital lobe damage via regulating excitatory amino acid neurotransmitters,energy metabolism and other metabolic pathways.

Objective To investigate the technical requirements for the 3.0T multi-modal quantitative MR imaging of the rabbit liver.Methods A total of 8 rabbits were scanned and T1 mapping,T2 mapping,MT and Gd EOB-DTPA dynamic enhancement images were acquired.For the dynamic enhanced scanning,injecting contrast medium was followed by saline flush with different combinations of injection flow rate (1.5 mL/s and 2 mL/s) and injection volume(6 mL and 8 mL).The quality of the images was assessed and analyzed statistically.Results The total scanning time was about 20-25 min.High-quality images were acquired by T1 mapping,T2 mapping and MT sequences.There was no significant difference in image quality among different groups in Gd-EOB-DTPA dynamic enhanced scanning(P＞0.05).Two rabbits died when the combination of injection flow rate of 2 mL/s and injection volume of 8 mL was used.Conclusion 3.0 T multi-modal quantitative MR scanning of rabbit liver can be achieved successfully if scanning parameters are properly chosen.

Objective:To investigate the relationship between the E2 and E4 alleles of apolipoprotein E (apoE) gene and myocardial infarction (MI) in type 2 diabetes Mellitus (T2DM) patients, and to explore the relationship between apoE polymorphism and blood lipid metabolism.Methods:This case control study was conducted from August 2016 to March 2020 in China-Japan Friendship Hospital, 3 459 inpatients with T2DM were included including 3 044 patients without MI (T2DM group) and 415 patients with MI (T2DM+MI group). Real time fluorescent quantitative PCR was used to detect apoE polymorphism. Automatic biochemical analyzer was used to detect lipid levels. Logistic regression analyses were performed to determine the association of apoE with risk of MI in patients with T2DM.Results:(1) The frequency of E4 allele in T2DM+MI group (12.29%, 102/830) was significantly higher than in T2DM group (9.13%,556/6 088), while the frequency of E2 allele in T2DM+MI group (7.35%,61/830) was significantly lower than that in T2DM group (8.21%,500/6 088), P=0.012. Logistic regression analyses showed that E4 allele carrier (E3/E4+E4/E4) faced a higher risk for MI in T2DM patients ( OR=1.48, 95% CI 1.14-1.92, P=0.003), while E2 allele carrier(E2/E3+E2/E2)did not face a higher risk of MI in T2DM patients ( OR=0.88, P=0.642). (2) The levels of apoE polymorphism and blood lipid: The levels of TC, LDL-C and apoB increased in the order of E4 allele, wild type and E2 allele ( P<0.05). The levels of HDL-C, apoA1 and apoE decreased in the order of E4 allele, Wild type and E2 allele ( P<0.05). Conclusion:The E4 allele is a risk factor for MI in T2DM patients, and apoE polymorphism can affect blood lipid level in this patent cohort.

Objective To study the influence of SCNIA intronic mutations in mRNA splicing in febrile seizures related epilepsy,and investigate the association between splicing changes and genotype-phenotype-inheritance pattern.Methods Molecular cloning of 5 SCN1A intronic mutations was performed in patients with partial epilepsy with antecedent febrile seizures plus (PEFS+) and Dravet syndrome (DS) through constructing mutant and wild-type plasmids of pTragetE2-3-4-5 and E24-25-26 by using Minigene splicing assay,and the in vitro expressions in HENK293 cells were detected.The mRNA splicing changes were analyzed qualitatively and quantitatively by reverse transcription (RT)-PCR and real time quantitative (q)-PCR.Results (1) Using RT-PCR,DS mutants presented a whole exon skipping without significant remain of normal mRNA transcripts,while PEFS+ mutants showed partial exon skipping or intronic insertion with coexistence of normal and aberrant mRNA transcripts.(2) Statistical differences were found between relative quantity (RQ) of aberrant and normal mRNA in PEFS+ mutant (c.473+5G＞A:4.92％±1.05％ and 6.10％±0.21％;c.473+5G＞C:7.97％±1.12％ and 3.94％ ±1.25％) and that in DS mutant (c.602+1G＞A:60.51％±1.81％ and 0.060％±0.022％,P＜0.05);similarly,there were statistical differences between relative RQ of normal and aberrant mRNA in PEFS+ mutant c.4853-25T＞A (71.22％±11.92％ and 7.38％±1.61％) and that in DS mutant c.4853-1G＞C (0.08％±0.01％ and 22.11％±2.83％,P＜0.05).Conclusion The position and difference of splicing patterns of SCNIA intronic mutations are potential molecular pathogenesis for phenotypic difference of febrile seizures related epilepsy.

OBJECTIVE To extract and isolate the four chemical components of Yao medicine Ventilago leiocarpa， and to conduct identification and content determination for them. METHODS The chemical components of V. leiocarpa were separated and purified by solvent extraction， extraction， silica gel column chromatography and preparative liquid chromatography； then the chemical structures of four isolated compounds were identified based on their spectral data. The contents of four components were determined by high performance liquid chromatography（HPLC）-quantitative analysis of multi-components by single-marker （QAMS） method， with the following chromatographic conditions： chromatographic column was Echway GowonTM C18 （250 mm× 4.6 mm， 5 μm）. The mobile phase was acetonitrile-0.1% phosphoric acid for gradient elution； the detection wavelength was 269 nm， and the column temperature was 25 ℃ . Using emodin as internal reference， the relative correction factors （fi/s） between emodin and the other 3 components were established and used to calculate the content. At the same time， the content of each component was calculated with the external standard method （ESM）， and the differences between these two methods were compared. RESULTS Four compounds were isolated from V. leiocarpa， and they were identified as emodin， frangulin A， pleuropyrone A， emodin-8-O-β-D-glucoside. The result of HPLC-QAMS showed that the fi/s of pleuropyrone A， emodin-8-O-β-D- glucoside and frangulin A were 1.147 2， 0.874 7 and 0.644 4， respectively. The content of these four components was measured as a good linearity （r≥0.999 6）； relative standard deviation （RSD） of precision， stability and reproducibility tests were all lower than 2.00%， and average recoveries were E-mail：dearhuangjianyou@126.com 99.41%-100.46%（RSD≤2.05%）. There was no significant difference between QAMS method and ESM （RSD＜3.00%）. CONCLUSIONS Emodin， frangulin A， pleuropyrone A and emodin- 8-O-β-D-glucoside are isolated from V. leiocarpa； among them， the last three components are all isolated from for the first time. The established HPLC-QAMS method is accurate and reliable for the determination of 4 components in V. leiocarpa， and can used for quality control of V. leiocarpa.
