ABSTRACT
Objective@#To explore the influence of birth weight and growth patterns during infancy on overweight and obesity among first grade primary school pupils, so as to provide a theoretical basis for the formulation of early life prevention and intervention policies.@*Methods@#In 2019, data related to routine physical examinations were collected for primary school pupils in the Minhang District of Shanghai, and information regarding birth and follow ups was collected retrospectively. Physical examination data of 4 434 pupils at 12 months of age were obtained. A multiple linear regression model was used to analyze the relationship between growth patterns during infancy and body mass index (BMI) in the first grade of primary school. A generalized linear model was employed to analyze the relationship between birth weight and growth patterns during infancy and overweight and obesity in the first grade of primary school. A hierarchical analysis was conducted.@*Results@#A linear relationship was observed between growth patterns during infancy and BMI and the BMI Z score of first grade primary school pupils [ β(β 95%CI)=0.30(0.24-0.35),0.12(0.10- 0.15 ), P <0.01]. In addition to subjects classified as small for gestational age (SGA), catch up growth during infancy was identified among subjects who were classified as appropriate for gestational age (AGA) and large for gestational age (LGA). LGA at birth and catch up growth during infancy were independent risk factors for overweight and obesity among first grade primary school children ( RR =1.31-1.55, P <0.05). The hierarchical analysis showed that catch up growth increased the risk of overweight and obesity among first grade primary school pupils classified as AGA [ RR(RR 95%CI )=1.74(1.42-2.14),1.87(1.56-2.26)], and increased the risk of obesity among first grade primary school pupils classified as SGA and LGA [ RR(RR 95%CI )=3.74(1.04-13.49),3.24(1.62-6.46)]( P <0.05). Among those who exhibited catch up growth during infancy, LGA increased the risk of obesity among first grade primary school pupils ( RR= 2.60 , 95%CI=1.35-5.02, P <0.01), but not the risk of being overweight ( P =0.13).@*Conclusion@#Birth weight and growth patterns during infancy have an impact on overweight and obesity among children in the first grade of primary school. It is suggested that attention should be paid to growth and physical development in early life for those classified as LGA and AGA, and catch up growth in children should be closely monitored.

ABSTRACT
Synchronous bilateral primary breast cancer refers to the simultaneous occurrence of primary cancers in both breasts. The overall morbidity is low. However, with the detection of occult breast cancer increasing recently, it shows an upward trend. The pathogenesis is not yet clear, old age, family history of primary breast cancer, sclerosing adenopathy of precancerous lesions and pathological characteristics of first cancer are currently recognized risk factors. Compared with unilateral breast cancer, prognosis for synchronous bilateral primary breast cancer is poor. Raise the risk awareness of high-risk women, check regularly to find non-palpable lesions as soon as possible. By taking various preventive treatments for patients with high-risk unilateral breast cancer, the incidence of breast cancer can be effectively reduced and the prognosis of patients can be improved. By reviewing the literature at home and abroad, it systematically expounds the risk factors, histopathological features, prognosis and preventive treatment of synchronous bilateral breast cancer.

Conclusion:Mindfulness-based therapy combined with risperidone treatment for emotional disorder in schizophrenic patients during the recovery period can effectively improve the emotional disorder,reduce the schizophrenia symptoms,and improve the social function of patients.
ABSTRACT
Additional sex combs-like 1 (ASXL1) interacts with BRCA1-associated protein 1 (BAP1) deubiquitinase to oppose the polycomb repressive complex 1 (PRC1)-mediated histone H2A ubiquitylation. Germline BAP1 mutations are found in a spectrum of human malignancies, while ASXL1 mutations recurrently occur in myeloid neoplasm and are associated with poor prognosis. Nearly all ASXL1 mutations are heterozygous frameshift or nonsense mutations in the middle or to a less extent the C-terminal region, resulting in the production of C-terminally truncated mutant ASXL1 proteins. How ASXL1 regulates specific target genes and how the C-terminal truncation of ASXL1 promotes leukemogenesis are unclear. Here, we report that ASXL1 interacts with forkhead transcription factors FOXK1 and FOXK2 to regulate a subset of FOXK1/K2 target genes. We show that the C-terminally truncated mutant ASXL1 proteins are expressed at much higher levels than the wild-type protein in ASXL1 heterozygous leukemia cells, and lose the ability to interact with FOXK1/K2. Specific deletion of the mutant allele eliminates the expression of C-terminally truncated ASXL1 and increases the association of wild-type ASXL1 with BAP1, thereby restoring the expression of BAP1-ASXL1-FOXK1/K2 target genes, particularly those involved in glucose metabolism, oxygen sensing, and JAK-STAT3 signaling pathways. In addition to FOXK1/K2, we also identify other DNA-binding transcription regulators including transcription factors (TFs) which interact with wild-type ASXL1, but not C-terminally truncated mutant. Our results suggest that ASXL1 mutations result in neomorphic alleles that contribute to leukemogenesis at least in part through dominantly inhibiting the wild-type ASXL1 from interacting with BAP1 and thereby impairing the function of ASXL1-BAP1-TF in regulating target genes and leukemia cell growth.
ABSTRACT
Objective: To determine the pharmacokinetic parameters based on distribution equilibrium theory by establishing the blood drug concentration-time curve of single elimination phase. Methods:Rats were intravenously infused with omeprazole at andante constant rate. Blood was collected at different time points during infusion, and drug concentration in plasma was detected by HPLC. Pharmacokinetic parameters were calculated with GraphPrism 6.0 software. Results: The concentration-time curve of omeprazole during intravenous infusion showed a first-order exponential relationship. The increase of plasma omeprazole concentration was rapid at the initial stage of the infusion and then became gradually slow as time went on. After 5 half lives a steady state was reached. The elimination rate constant (K) of omeprazole in rats was (2.95±0.67)h-1. The half-life was (15±4)min. The apparent volume of distribution was (0.30±0.17)L, and the drug clearance was (0.83±0.33)L/h. Conclusion: The distribution of the drug in the body is basically balanced during the process of andante constant-rate intravenous infusion, and there is no interference of distribution. The measured pharmacokinetic parameters are closer to the reality.

ABSTRACT
Objective:To investigate the risk factors of lymph node metastasis in the cervical region VI (central region) in patients with papillary thyroid microcarcinoma (PTMC) of cN0 stage, and then to determine whether to perform prophylactic central lymph node dissection.Methods:The clinical data of 500 patients with PTMC who underwent surgery from Jan. 2013 to Dec. 2015 in Ningbo First Hospital were retrospectively analyzed. Due to the pathological results, all patients were divided into two groups: central lymph node metastasis (CLNM) positive group and CLNM negative group. SPSS18.0 was used for analyzing.Results:Of the 500 cases of PTMC of cN0 stage, 142 cases had lymph node metastasis. Gender, the maximum tumor diameter, tumor invasion outside the gland, boundary, calcification in tumor, single or multiple lesions, aspect ratio and blood flow were risk factors for CLNM in patients with PTMC of cN0 stage. Multivariate analysis identified that male ( P=0.014) , tumor size ≥0.5 cm ( P=0.03) , tumor invasion outside the gland ( P=0.003) , unclear boundary ( P=0.032) , calcification ( P=0.009) , aspect ratio ≥1 ( P=0.001) were independent predictors factors for CLNM of PTMC. Conclusion:Male, unclear boundary, tumor size ≥0.5cm, tumor invasion outside the gland, calcification, aspect ratio ≥1 are the risk factors of CLNM in patients with cN0 PTMC. Prophylactic central lymph node dissection should be performed for patients without lymph node metastasis but with one risk factor or more.
ABSTRACT
L_9(3~4) orthogonal experiment design was used to optimize the preparation of the patches,and investigate its affecting factors and skin irritation. Eugenol was taken as the index component to study the release behavior in vitro and percutaneous penetration of Cangai oil transfersomes patches by HPLC.The results showed that the optimal prescription for preparing Cangai oil transfersomes patches were Eudragit E100 0.6 g, succinic acid 0.08 g,triethyl citrate 0.25 g,glycerol 0.2 g.Patches prepared by the preferred preparation had a flat appearance without obvious bubbles.The initial adhesion was 18.33±2.52, the stickiness was(30.01±2.45) min,and the peel strength was(5.62±0.95) kN·m~(-1).The results of affecting factors experiment showed the order of factors affecting its adhesion was humidity>temperature>lighting,and the skin irritation test results showed no significant skin irritation after 24 h of single administration. The results of drug release behavior in vitro showed that the release and the percutaneous penetration of both Cangai oil patches and Cangai oil transfersomes patches conformed to the Higuchi equation.The release amount of eugenol were 80.66% and 82.25% at 72 h, with no significant difference. The cumulative permeation area of eugenol per unit area reached(0.195 6±0.065 9),(0.131 0±0.045 5) mg·cm~(-2) at 72 h, with significant differences(P<0.05).The experiment results proved that the preparation process of Cangai oil transfersomes patches was stable,and the prepared patches had a good adhesion. At the same time,the preparation of transfersomes patches could alleviate and control the release of the drug to a certain extent, and provide a certain experimental basis for clinical pediatric drug safety.

Objective To explore the relationship between carotid plaque microcalcifcation and ischemic stroke (including transient ischemic attack) and the value of carotid microcalcification in predicting ischemic stroke.Methods Twenty-six patients in accordance with atherothrombosis models classified by Korean modified TOAST classification were enrolled in this study from November 2016 to March 2017.The microcalcification of the bilateral carotid was detected by Micropure imaging and the severity of intracranial ischemic focal lesions was evaluated by Alberta stroke programme early CT scale (ASPECT).The relation of ASPECT scores with microcalcification of the bilateral carotid was analyzed,and the value of carotid microcalcification in predicting ischemic stroke was analyzed by receiver operating characteristic curve method.Results Microcalcifition was detected in 27 of the total 52 carotids (51.92％) in 19 patients,which localized in the fibrous cap in 23 carotids (85.19％) and the basilar part of the plaque in 4 carotids (14.81％).The microcalcification surrounded the macrocalcifiation in 14 carotids (51.85％).The ASPECT scores were 10.85±1.43 in the microcalcifition side,which were significantly higher than those in the side without microcalcifition (11.80±1.19,t=2.584,P=0.013).The area under the curve was 0.673,with sensitivity of 0.667 and specificity of 0.680.Conclusion Micropure imaging maybe a new approach to detect the carotid microcalcification,and plaques with microcalcifition mav easilv cause ipsilateral ischemic stroke.

Objective To study the value of expanded-National Institutes of Health Stroke Scale (e-NIHSS) in evaluating the neurological signs of medullary infarction.Methods One hundred and thirteen patients with primary medullary infarction proved by magnetic resonance imaging were enrolled and divided into medial medullary infarction (MMI) group (n=41) and lateral medullary infarction (LMI) group (n=72).Risk factors of stroke and neurological signs evaluated by NIHSS and e-NIHSS were recorded and compared between the two groups.Results The age and prevalence of diabetes in MMI group were significantly older/higher than those in LMI group (P＜0.05).The major neurological signs of MMI were limb weakness (95.12％),dysphagia (36.59％),facial plasy (34.15％) and dysarthria (31.71％).And the major neurological signs of LMI were dysphagia (63.89％),truncal ataxia (54.17％),sensory dysfunction (50.00％) and dysarthia (48.61％).All the patients had significantly higher e-NIHSS scores than NIHSS scores (5.40±2.74 vs.2.96±2.22,P=0.000),which was similar in MMI group (e-NIHSS:5.34±3.20 vs.NIHSS:4.07±2.55,P=0.000) and in LMI group (e-NIHSS:5.43±2.47 vs.NIHSS:2.33±1.74,P=0.000).The e-NIHSS scores increased 2.57±1.99 than NIHSS scores in all the patients,which were 1.63±2.25 in MMI group and 3.10±1.62 in LMI higher than NIHSS scores;the differences were statistically significant (P＜0.05).Conclusion The e-NIHSS could improve the sensitivity of NIHSS in evaluating the neurological signs of medullary infarction,which is better in evaluating LMI than in evaluating MMI.
