Aurora kinases constitute a highly evolutionarily conserved family of serine/threonine kinases, which includes Aurora A, Aurora B, and Aurora C. These kinases are dynamically distributed throughout the cell cycle, and ensure the normal completion of the cell cycle by regulating centrosome maturation and separation, bipolar spindle assembly and stabilization, accurate separation of chromosomes, and efficient division of cytoplasm during mitosis. In recent years, it has been shown that Aurora kinases are overexpressed in a variety of solid tumors in the human body. The overexpression of Aurora kinases leads to abnormal mitosis, causes genetic instability, and is closely related to the occurrence, proliferation, and poor prognosis of tumors, which indicates that these kinases could be novel anti- tumor targets. Currently, Aurora kinase inhibitors are considered as novel candidates for molecular targeted therapies. Some of these inhibitors with strong anti-tumor activity have even entered clinical trials. In this article, we have reviewed the relationship between the biological characteristics of Aurora kinases, Aurora kinase inhibitors, and the occurrence and development of gastrointestinal tumors.

Infantile neuroaxonal dystrophy (INAD) is a rare autosome-recessive disease characterized by progressive motor and cognitive regression.The PLA2G6 gene is its causative gene,which encodes calcium-independent phospholipase A2 enzyme (iPLA2-VIA).The diagnosis of INAD is difficult because of its clinical heterogeneity,and the rate of misdiagnosis is high.The purpose of this study is to describe the clinical characteristics,molecular genetics,treatment and prognosis of INAD to improve the acknowledgement of INAD in medical workers and to help make an early diagnosis of INAD.

Objective To summarize the clinical features of global developmental delay (GDD) children,and to explore the relationship between severity of GDD and social-culture factors.Methods Sign the informed consent before enrollment.Collect clinical data in detail about 100 GDD children (GDD group) and 95 children with normal development (healthy control group),and analyze their regular clinical data,physical examination,intellectual disability test,electroencephalography (EEG) and cranial imaging test.Spearman rank correlation was used to analyze the differences of social and cultural factors between GDD group and healthy control group,such as maternal reproductive age,parental education level and family economic status.At the same time,we compared the lag degree of total developmental quotient and the degree of developmental retardation of five energy areas with the above factors.Results Significant associations were found between GDD and maternal/paternal education,economic level of family,but no sgnificant association was found between maternal age and GDD.And analysis in the relationship between severity of delay in all domains of the child's developmental status about language and social-culture factors,we only obtained the severity of delay in abilities about language is related with maternal education.Spearman rank correlation statistics explains that if there are the lower level of education with mothers,the delay of language domain will more severe (rs =-0.505,P ＜ 0.05).Conclusions Significant associations were found between GDD and maternal/paternal education,economic level of family.The higher maternal education was an important protective factor against risk of GDD.Improving the cognition of parents in child health care,early be diagnosed,early be intervened,is the most important for children with language development.

Objective: To summarize the clinical features and gene variation characteristics of a child with Okur-Chung syndrome caused by CSNK2A1 gene variation. Methods: The medical records of one patient who was diagnosed with Okur-Chung syndrome in Department of Pediatrics, Xiangya Hospital of Central South University in July 2018 were analyzed. Using "CSNK2A1" gene as the keyword, relevant information about CSNK2A1 gene was searched at CNKI, Wangfang Data, OMIM, PubMed, ClinVar, Decipher (until August 2018). The characteristics of CSNK2A1 gene variation and the clinical phenotype of children with Okur-Chung syndrome were summarized. Results: The boy, 1 year and 8 months old, was sent to hospital at the age of 1 year and 6 months because of delayed growth for more than 1 year. He was susceptible to cough while eating or drinking. He was also suffering from constipation and poor sleep. Physical examination showed that his body weight was 10.2 kg, microcephalus, broad nasal bridge, micrognathia and hypotonia were observed. Whole exome-sequencing test identified a de novo heterozygous variation c.524A>G (p.D175G) in CSNK2A1 gene. This was the first case report of CSNK2A1 gene variation in the mainland of China. So far, a total of 52 cases were reported worldwide (52 single nucleotide variants), including 35 cases in 7 articles, 9 cases in Decipher database and 14 cases in ClinVar database, 6 of which were also reported in PubMed. In previously reported 52 cases, there were 48 missense variants, whereas, splice and frameshift variations were found in 3 cases and 1 case, respectively. Among the variation sites, p.K198R was the most common sites (12 cases), followed by p.R47 (6 cases), p.R80H (4 cases) and p.S51 (4 cases). Among these 52 cases, only 27 cases have been elaborately described in other studies, so the clinical characteristics were summarized in 28 cases eventually (including 27 cases in the articles and this patient), 27 of whom presented severe intellectual disability or global development delay, 1 case with mild language development delay, and 19 had hypotonia; 8 had autism spectrum disorders, 5 had attention deficit hyperactivity disorder, and 9 had sleep problems. 20 had dysmorphic facial features, 10 of them had microcephalus. 16 had failure to thrive or short stature, 12 had gastrointestinal or oromotor problem, 5 had immunological problem, and 4 had skin abnormalities. Conclusions The main clinical feature of patients with CSNK2A1 gene variations is intellectual disability with multiple systems involved, such as microcephalus, abnormal facial shape and hypotonia. The variation of CSNK2A1 gene is the cause of Okur-Chung syndrome. Missense variation is the main cause, and P. K198R is the hotspot variation.

postoperative recovery time,increase the number of lymph node dissection,however,it will increase the treatment expense.

Strengthening the performance appraisal of tertiary public hospitals is key to advancing the healthcare system reform in China. Based on the practical experience of performance appraisal of tertiary public hospitals in one city, the authors named the bottlenecks and causes impeding effective implementation of performance appraisal from the aspects of data quality, index orientation, index determination and index calculation. On such basis, they put forward corresponding countermeasures and suggestions, such as effective control of the data quality, dialectical view of the index orientation, scientific allocation of performance indicator weight, and formulation fair and reasonable index scoring methods, aiming to provide references for performance appraisal in the future.

Cardio-facio-cutaneous (CFC) syndrome is an extremely rare autosomal dominant genetic disease due to BRAF and other gene mutations. The main characteristics of the patients are craniofacial deformities, cardiac malformations, skin abnormalities, delay of language and motor development, gastrointestinal dysfunction, intellectual disability, and epilepsy. In this case, the child has a typical CFC syndrome face and developmental delay. The gene results of the second-generation sequencing technology showed that there was a mutation site c.1741A>G (p. Asn581Asp) (heterozygous) in exon 14 of the BRAF (NM_004333.5) gene. The mutation was not observed in the child's parents. The above-mentioned mutation may be a de novo mutation. There is no effective therapy for this disease so far.

Objective: To explore the application value of early postoperative enteral eco-immune nutrition in the nutritional support treatment for intra-abdominal infection. Methods: The prospective study was conducted. The clinicopathological data of 62 patients with intra-abdominal infection who were admitted to the 940 Hospital of the People′s Liberation Army Joint Service Support Force from February 2018 to December 2018 were collected. All patients were randomly divided into two groups by the envelope method with double-blind technique, including patients who began being given enteral eco-immune nutrition preparation at postoperative 24-48 hours in eco-immune group and patients who began being given simple enteral nutrition preparation at 24-48 hours in control group. Observation indicators: (1) analysis of immune function indices before treatment and after 7 days of treatment in the two groups; (2) postoperative conditions in the two groups; (3) follow-up. Follow-up using telephone interview was performed to detect complications and recurrence of infection up to May 2019. Measurement data with normal distribution were represented as Mean±SD, and intra-group comparison and comparison between groups were analyzed using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Results: Sixty-two patients were screened for eligibility, including 38 males and 24 females, aged (54±14)years, with the range of 22-81 years. There were 30 in the eco-immune group and 32 in the control group. (1) Analysis of immune function indices before treatment and after 7 days of treatment in the two groups: before treatment, the percentages of CD3⁺, CD4⁺, CD8⁺, ratio of CD4⁺ /CD8⁺, count of natural killer (NK) cells, levels of blood endotoxin and immunoglobulin A (IgA) for the eco-immune group were 61%±12%, 34%±5%, 28%±5%, 1.25±0.34, 17.26%±2.74%, (2.4±0.3)ng/L, and (1.7±0.5)g/L, versus 59%±11%, 33%±5%, 27%±4%, 1.27±0.36, 16.96%±2.99%, (2.5±0.5)ng/L, (1.8±0.5)g/L for the control group, respectively, there were no significant differences between the two groups (t=-0.563, -0.354, -0.987, 0.327, -0.462, 0.887, 0.991, P>0.05). After 7 days of treatment, the above indices for the eco-immune group were 62%±8%, 37%±6%, 27%±8%, 1.45±0.32, 22.63%±7.25%, (2.2±0.4)ng/L, and (2.3±0.4)g/L, versus 58%±8%, 32%±4%, 27%±6%, 1.26±0.22, 16.26%±2.10%, (2.7±0.6)ng/L, and (2.0±0.4)g/L for the control group, respectively, there were significant differences in the percentages of CD3⁺, CD4⁺, ratio of CD4⁺ /CD8⁺, count of NK cells, levels of blood endotoxin and IgA (t=-2.393, -4.336, -3.074, -5.338, 4.010, -3.155, P<0.05), but no significant difference in the percentage of CD8⁺ between the two groups (t=0.077, P>0.05). In the eco-immune group, the percentage of CD4⁺, ratio of CD4⁺ /CD8⁺, count of NK cells, levels of blood endotoxin and IgA showed significant differences after 7 days of treatment (t=-2.899, -2.739, -4.385, 2.157, -5.788, P<0.05), but the percentages of CD3⁺ and CD8⁺ showed no significant differences after 7 days of treatment (t=-0.490, 1.193, P>0.05). In the control group, the percentage of CD8⁺ and level of IgA showed significant differences after 7 days of treatment (t=3.659, -2.258, P<0.05), but the percentage of CD4⁺, ratio of CD4⁺ /CD8⁺, count of NK cells, and level of blood endotoxin showed no significant differences after 7 days of treatment (t=0.157, 0.759, 1.132, 1.212, -0.532, P>0.05). (2) Postoperative conditions in the two groups: the time to first flatus and duration of postoperative hospital stay of the eco-immune group were (2.4±0.5)days and (8±4)days, respectively, versus (2.9±0.7)days and (11±7)days of the control group; there were significant differences in the above indices between the two groups (t=-3.017, -2.764, P<0.05). In the eco-immune group, the incidence of complication was 6.7%(2/30), including 1 case of wound infection, 1 case of pulmonary infection. In the control group, the incidence of complication was 31.2%(10/32), including 6 cases of wound infection, 2 cases of pulmonary infection, 1 case of intra-abdominal infection, and 1 case of systemic inflammatory response syndrome. There was a significant difference in the incidence of complication between the two groups (χ²=4.122, P<0.05). The patients with infection were recovered after corresponding systematic conservative treatments. (3) Follow-up: of the 62 patients, 46 were followed up for 3-9 months, with a median follow-up time of 6 months, including 26 in the eco-immune group and 20 in the control group. During the follow-up, no complication or infection recurred in the two groups. Conclusion Compared with simple enteral nutrition, early postoperative enteral eco-immune nutrition in the nutritional support treatment is safe and effective for patients with intra-abdominal infection, which can enhance the immune function of patients, shorten the recovery time of patients, and reduce the incidence of infection complications.

Börjeson-Forssman-Lehmann syndrome (BFLS) is a rare X-linked intellectual disability. The main features of the patients include intellectual disability/global developmental delay, characteristic face, anomalies of fingers and toes, hypogonadism, linear skin hyperpigmentation, and tooth abnormalities in female patients, and obesity in male patients. A case of BFLS caused by a novel mutation of PHF6 gene who was treated in the Department of Pediatrics, Xiangya Hospital, Central South University was reported. The 11 months old girl presented the following symptons: Global developmental delay, characteristic face, sparse hair, ocular hypertelorism, flat nasal bridge, hairy anterior to the tragus, thin upper lip, dental anomalies, ankyloglossia, simian line, tapering fingers, camptodactylia, and linear skin hyperpigmentation. The gene results of the second-generation sequencing technology showed that there was a novel heterozygous mutation site c.346C>T (p.Arg116*) of the PHF6 (NM032458.3), variation rating as pathogenic variation. During the follow-up, the patient developed astigmatism, strabismus, awake bruxism, and stereotyped behavior, and the linear skin hyperpigmentation became gradually more evident. The disease is lack of effective therapy so far.
