Considerable clinical and experimental evidence supports that liver injury in acute pancreatitis (AP) is a sign for the potential progression to systemic inflammatory reaction.The Kupffer cells,various cytokines and macrophage migration inhibitory factor (MIF) play important roles in the pathogenesis of AP associated liver injury.However,the specific molecular mechanism of the liver damage remains uncertain.Therefore,efforts should be made to clarify the regulatory mechanism and related cell signaling disorders of liver injury in AP,which could not only identify novel therapeutic targets,but also provide new insight into improving the clinical treatment.Here our review discusses the recent research progress on the etiology,pathology and diagnosis and treatments of liver injury in AP.

Objective To investigate the effects of low carbohydrate diet in treating non-alcoholic fatty liver disease (NAFLD) patients.Methods 58 male NAFLD patients selected in Renmin Hospital of Wuhan University from September 2010 to October 2012 were divided with random number table into low-carbohydrate diet group (L group,n =31) and medium-carbohydrate diet group (M group,n =27).Waistline,weight,serum glucose level,insulin secretion,glutamic-pyruvic transaminase (ALT),aspartate transaminase (AST)、high-density lipoprotein (HDL),low-density lipoprotein (LDL),total cholesterol (TC),and triglyceride (TG) of the patients were measured.Results Six patients were excluded from this research,2 in L group and 4 in M group.After 6-week's dietary intervention,blood glucose level and insulin secretion were significantly lower in L group than in M group [(4.3±1.4) mol/Lvs.(5.0±0.9) mol/L,P=0.004; (6.1 ±1.5) U/mlvs.(8.9 ± 1.4) U/ml,P =0.001].The levels of ALT and AST in L group were significantly lower than those in Mgroup[(30.23±3.34) U/Lvs.(42.33±4.46) U/L,P=0.003; (31.19±4.13) U/Lvs.(45.21±3.73) U/L,P =0.001].The levels of LDL and TG in L group were also significantly lower than those in M group [(1.13±0.22) mmol/Lvs.(2.71±0.67) mmol/L,P=0.001; (0.99±0.74) mmol/Lvs.(1.42±1.06) mmol/L,P =0.001].Conclusion In NAFLD patients,low-carbohydrate diet can improve blood glucose level,insulin secretion,liver function,and lipid metabolism disorders.

Objective: To understand associated factors of myopia among middle school students in Zhengzhou and to explore the correlation between myopia with overweight and obesity, to provide a scientific basis for myopia prevention. Methods: A total of 3 297 middle school students from 8 middle schools in Erqi District, Zhongmu County and Xingyang County of Zhengzhou City were selected by a cluster random sampling method to participate in vision testing and questionnaire survey. Chi square test, and Logistic regression analysis were used. Results: Overall prevalence of myopia of middle school students was 80.5%, overweight 14.7%, obesity 10.1% in Zhengzhou. The prevalence of myopia differed significantly by schooling stage, parental myopia status and sex ( χ 2= 18.34, 23.55, 8.98, 26.53, 27.46, 47.25, P <0.05). Significant differences in myopia detection rate by after school homework duration were observed in boys and the entire population( χ 2=12.40, 15.25, P <0.01), and significant differences in myopia detection rate by body mass index (BMI) were only observed in boys ( χ 2=6.32, P <0.05). The distribution of myopia severity was statistically significant by sex among junior school students, and by BMI categories among high school students ( χ 2=22.71, 20.37, P <0.01). Multivariate binary Logistic regression analysis showed that the risk for myopia among school students who were overweight and obese was 1.81 times higher than that of students who were not overweight and obese( P <0.01). Conclusion Overweight and obesity might increase the risk of myopia among middle school students, targeted measures should be taken to maintain the healthy weight of middle school students and reduce the risk of myopia.

Teaching ancillary facilities: the proportion of centralized water supply was 65.0% (347), toilet with hand washing facilities was 81.6% (436), these two indicators showed an increasing trend, hand washing facilities in campus was 70.6% (377), showed a decreasing trend, the rate of each year differed significantly( χ 2=88.62, 42.71 , 123.53, P <0.05). Conclusion The overall situation of teaching environment in Zhengzhou primary and secondary schools is relatively good, the qualified rate of most indicators of teaching facilities increased from 2014 to 2018. However, there are still some indicators to be strengthened.

Objective: Accumulating evidence has shown that aberrant alternative splicing events are closely associated with the onset and development of cancer. However, whether genetic variants-associated alternative splicing is linked to risk of endometrial cancer remains largely uncertain. Methods: We identified single nucleotide polymorphisms (SNPs) locates in the splicing number trait locus (sQTL) of endometrial cancer using the CancerSplicing QTL database. In parallel with bioinformatics analysis, we conducted a case-control study comprising 2,000 cases and 2,013 controls to assess the association between identified SNP which possesses mRNA splicing function and endometrial cancer susceptibility. Furthermore, we used the Kaplan-Meier Plotter, The Human Protein Atlas, SPNR, and Spliceman2 databases for sQTL and differential gene expression analyses to identify the genetic variant which most potentially influence the risk of endometrial cancer through alternative splicing to reveal the potential mechanism by which candidate SNPs regulate the risk of endometrial cancer. Results: The results indicated that SNP rs7128029 AConclusion These findings suggest that SNP rs7128029-mediated alternative splicing events in PSMD13 are associated with endometrial cancer risk and may be a potential early screening biomarker for endometrial cancer-susceptible populations.

With the aging of population， osteoporosis has become one of the main diseases endangering the health of the elderly in China. Therefore， the research on osteoporosis has become a hot spot. Since Chinese medicines demonstrate significant therapeutic effects on osteoporosis， this issue is attracting increasing attention from researchers， especially in the deciphering of the molecular mechanism. This paper introduces the mechanism of the prevention and treatment of osteoporosis by Chinese medicines via the mitogen-activated protein kinase （MAPK） signaling pathway， aiming to provide a theoretical basis for deciphering the mechanism of Chinese medicines in the treatment of osteoporosis and promoting their clinical application. MAPK signaling pathway mainly involves p38 MAPK， extracellular signal-regulated kinase 1/2 （ERK1/2）， c-Jun N-terminal kinase （JNK）， and extracellular signal-regulated kinase 5 （ERK5）. Studies have shown that these proteins play a role in the progression of osteoporosis by regulating cell proliferation， differentiation， and apoptosis. Chinese medicines as a unique therapy with Chinese characteristics has definite efficacy， high safety， and mild side effects. Researchers have proved by experiments that the extracts or compounds of Chinese medicines can significantly mitigate osteoporosis by regulating the proteins involved in the MAPK signaling pathway. Therefore， this article reviews the relevant studies with focus on these proteins.

In recent years， with the changes of population structure and the aggravation of aging， the prevalence of osteoporosis is increasing year by year. Osteoporosis poses great impacts on the body and family life of the patients and increases the burden on the society. Therefore， the research on osteoporosis is urgent and significant. The imbalance between osteoblasts， osteocytes， and osteoclasts causes abnormal bone metabolism， which destroys the fine structure of bone and increases bone fragility， thus increasing the risk of fracture. Although the pathogenesis of osteoporosis is complex， researchers have confirmed that the imbalance of the endocrine system directly or indirectly promotes the occurrence and development of osteoporosis. Traditional Chinese medicine （TCM） is a treasure of Chinese traditional culture and plays a key role in safeguarding the public health. With unique therapeutic effects and advantages， TCM has been widely accepted. Chinese medicines， moxibustion， acupuncture and other TCM therapies have play a unique role in the treatment of osteoporosis. Particularly， TCM prevention and treatment of osteoporosis by regulating the endocrine system has received extensive attention. By reviewing relevant literature， this paper introduces the research progress in the TCM modulation of bone metabolism and alleviation of bone loss by regulating estrogen， calcitonin， and parathyroid hormone in the endocrine system and affecting the hypothalamus capable of regulating these hormones， aiming to provide ideas for the TCM treatment of osteoporosis.

Besides， this paper analyzed the prospects of CAG data science in improving data governance ability and knowledge discovery efficiency， deepening the level of knowledge sharing， promoting interdisciplinary integration， and strengthening the integration process of industry， academia and research.

This paper summarized professor JIA Hongxiao's experience in treating cognitive impairments in schizophrenia patients upon five spirits stored in corresponding viscera theory. By elucidating the cognitive psychological connotation of the five spirits stored in corresponding viscera theory， it is proposed that the cognitive impairment of schizophrenia should be differentiated and treated based on the symptom characteristics of different cognitive domain impairments in schizophrenia. The key pathogenesis of impairments to cognitive domains such as information processing speed， executive control ability and will is kidney deficiency， liver hyperactivity， and heart spirit restlessness， for which the treatment is to boost the kidney and calm the liver， nourish the heart and calm the mind， using Shizhen Anshen Formula （石珍安神方） modifications. The main pathogenesis of memory and attention cognitive impairment is spleen-kidney depletion and lung corporeal soul failing to descend， for which it is suggested to fortify the spleen and supplement kidney， boost lung and direct qi downward using Jianpi Bushen Formula （健脾补肾方） modifications.

Objective: To investigate the correlation between clinical phenotype, electroencephalogram (EEG) characteristics and genotype in children with Angelman syndrome(AS). Methods: A total of 103 children with AS at Department of Neurology, Children′s Hospital of Fudan University from June 2017 to June 2018, were included in this study.The information of clinical characteristics, EEG manifestations, genotypes as well as the epileptic outcome were collected retrospectively.The correlations between clinical phenotype, genotype, and epileptic outcome were evaluated. Results: (1) Of the 103 cases, 48 were male (46.6%) and 55 were female (53.4%). (2) Genotypes on AS critical region were maternal chromosome 15q11.2-q13 [86.4%(89/103 cases)], paternal uniparental disomy [3.9%(4/103 cases)], imprinting defects [1.9%(2/103 cases)], and mutations in the maternal copy of UBE3A [7.8%(8/103 cases)]. (3) Apparent happy demeanor or smile and general developmental delay were observed in all AS children.Dyskinesia accounted for 98.1% (101/103 cases), followed by oral movement or suck disorders [97.1%(100/103 cases)] and abnormal posture [67.0%(69/103 cases)]. The proportion of acquired small head circumfe-rence or microcephaly, flat occiput or occipital groove and wide-spaced teeth were 61.2%(63/103 cases), 85.4%(88/103 cases) and 44.7%(46/103 cases), respectively.(4) Behavioral problems like fascination with water, sleep problems and feeding difficulties were found in 86.4%(89/103 cases), 89.3%(92/103 cases) and 85.5%(88/103 cases) of the children, respectively.Sleep disorders [94.4%(84/89 cases) vs.57.1%(8/14 cases)] and feeding difficulties [93.3%(83/89 cases) vs.35.7%(5/14 cases)] were more frequently seen in children with maternal absence group, compared those with no absence, and the differences were statistically significant (all P<0.05). (5) Epilepsy was present in 77.7% (80/103 cases) of children with onset age varying from 8 to 72 months and 80.8% (59/73 cases) were developing seizures prior to 3 years old.Children with maternal absence showed more multiple seizure types than those with no absence[41.7%(32/68 cases) vs.0(0 case)], and the difference was statistically significant(P<0.05). Children with well-controlled epilepsy had more atonic seizure, compared with those with poorly controlled seizure [48.3%(14/29 cases) vs.18.5%(4/27 cases)], and the difference was statistically significant(P<0.05). Conclusions Sleep disorders, feeding difficulties in infancy and multiple seizure types are more commonly seen in AS children with maternal absence.Atonic seizure is easier to be controlled over other types of seizures.
