Endometrial cancer is one of the malignant tumors of female reproductive system. The prognosis of advanced endometrial cancer is poor. How to improve the overall survival rate and improve the prognosis of patients with advanced endometrial cancer is still one of the clinical problems. In recent years, the research on tumor gene changes is increasing gradually. Epigenetics is the study of genetic changes in gene expression without changing the nucleotide sequence of genes. Epigenetics includes many phenomena, such as DNA methylation, microRNA expression and gene silencing, chromatin remodeling. These changes may be important factors in the occurrence and development of tumors, and may become new therapeutic targets for tumors. With the study on epigenetics of endometrial cancer in the future, new therapeutic targets may be found. Meanwhile, those study may provide new ideas for targeted therapy of endometrial cancer.

The clinical data of a child diagnosed with β-ketothiolase deficiency in Children′s Hospital of Chongqing Medical University in September 2018 were reviewed, and nutritional intervention and follow-up were carried out.The male child was 1 year and 4 months old, and he had clinical manifestations, including vomiting, diarrhea, mental depression and repeated metabolic acid poisoning.Gene detection: heterozygous variation of ACAT1 gene c. 401T>C (p.M134T) and c. 481T > C (p.Y161H). This study was mainly aimed at children with β-ketothiolase deficiency for nutritional treatment of individualized nutrition therapy, suggests that energy supply should be guaranteed and protein and fat intake should be limited in acute stage, and protein and fat intake should be increased gradually in remission stage, which can not only ensure growth and development, but also reduce the occurrence of metabolic crisis.

Objective To explore the forensic identification points of deaths caused by secondary dam-ages of road traffic accidents. Methods Seventeen deaths caused by secondary dam ages of road traffic accidents were collected. Through scene investigation and necropsy, the basic inform ation of the acci-dents, distribution and property of the injuries, and other inform ation were collected. A ccording to the collected data, the scene was reconstructed in order to confirm the injury process, analyze the way, mechanism and severity of injury, distinguish antem ortem injury from postm ortem injury, and determ ine the cause of deaths. Results C ertain features such as serious injuries, multiple traum as, com bined in-juries, co-existence of antem ortem and postm ortem injuries, multiple causes of wounds, com plex injury mechanism , as well as the mutual dam aging and overlapping injuries were quite characteristically noted in these secondary traffic accident cases. Conclusion Forensic assessment of deaths caused by secondary dam ages of road traffic accidents should be synthetically analyzed and judged through scene investigation and necropsy.

Objective To study the correlation between serum lipids and thyroid function after withdrawn of thyroid hormone in the patients with differentiated thyroid cancer .Methods One hundred and thirty cases of differentiated thyroid carcinoma treated by operative therapy in our hospital form August 2014 to August 2015 were selected .Serum FT4 ,TSH ,FT3 ,triglyceride ,total cho-lesterol ,LDL-C ,HDL-C indexes were detected before discontinuation of levothyroxine sodium (L-T4) ,before operation and 3 weeks after drug withdrawn .Thus the correlation between blood lipid levels and thyroid function was analyzed .Results The HDL-C and the TSH level was positively related before operation (P<0 .05) ,other indexes had no obvious correlation with thyroid function (P>0 .05);the blood lipid levels after medication withdrawn had no obvious correlation with thyroid function (P>0 .05);the total cholesterol levels after medication discontinuation had negative correlation with FT 3 and FT4 levels(P<0 .05);HDL-C was nega-tively correlated with FT3 and FT4 levels(P<0 .05) ,and positively correlated with TSH level (P<0 .05);LDL-C was negatively correlated with FT4 (P<0 .05) .Conclusion When the application treatment of thyroid hormone is suspended ,with the TSH level increase ,the HDL-C level has somewhat elevation ;total cholesterol ,HDL-C and LDL-C levels are negatively correlated with FT 3 and FT4 ,after discontinuation of medication withdrawn ,the blood lipids metabolism abnormality is closely related with thyroid function decline .

AIM: To study the influence of basic fibroblast growth factor(bFGF) on treating ed palatal perforation in rats. METHODS: bFGF was given to the early palatal perforation in rat. The granulation tissues in perforations were grossly and pathologically obserVed. RESULTS: The the of wound healing was significantly in- crease in the bFGF group (P

Objective Candidas rank as the second factor of deep fungal infection .This study aimed to investigate the rela-tionship between Candidas and melanin by screening clinically isolated melanin -producing Candidas . Methods We incubated 360 strains of clinically isolated Candidas with caffeic acid , DOPA agar , and minimal medium at a temperature of 35℃, with Cryptococcus neoformans as the positive control .We observed the changes in the culture media using transmission electron microscopy (TEM) and electron spin resonance ( ESR) spectroscopy . Results Cryptococcus neoforman produced pigmentation in all the three types of medi -um.At 5 days, a standard strain of Candida albicans SC 5314 turned dark brown in the DOPA agar and minimal medium and , at 10 days, 12 and 15 of the 360 Candida strains turned dark brown in the DOPA agar and minimal medium , respectively, which were not shown to be melanin by TEM and ESR spectroscopy . Conclusion Culture media are not reliable enough for the identification of mel-anin-producing Candidas , and the observations need to be further verified by TEM and ESR spectroscopy .

Objective To explore the effect and mechanism of Gli2 on EMT and invasion in the hepatocellular car-cinoma cell line SMMC-7721.Methods shRNA of Gli2 and Negative control (NC) shRNA were constructed and transfected into SMMC-7721 cells.shRNA-Gli2 group,shRNA-NC group and blank group were set up .Transwell chambers assay , adhesion experiments were used to detect the ability of invasion ,homogeneous and heterogeneous cells intercellular adhesion of each group .Meanwhile, the qRT-PCR, Western blot were used to examine Gli2, E-cadherin ,N-cadherin and vimentin mRNA and protein expression .Results In different hepatocellular carcinoma cell lines and be along with the increasing ability of the invasion in hepatocellular carcinoma cell lines , Gli2 expres-sion was higher .Compared with the shRNA-NC group and blank control group ,the interfered group extensive cells invasion ability was inhibited ( P <0.05 ) , homogeneous cells intercellular adhesion increased and heterogeneous cells intercellular was opposite ( P <0.05 ) , meanwhile , the expression of E-cadherin was declined significantly ( P<0.05 ) ,the expression of N-cadherin , vimentin raised significantly ( P<0.05 ) .Conclusions Silencing Gli2 gene can reverse the EMT of the hepatocellular carcinoma cell line SMMC-7721 and inhibit cell invasion ,its mecha-
nism may be related to the up-regulation of E-cadherin and the dow N-regulation of N-cadherin, vimentin.

OBJECTIVETo evaluate the incidence of two-rooted mandibular premolar morphology using full-mouth periapical film series in a Chinese population, with particular emphasis on bilateral incidence, so as to provide a clinical anatomical basis for root canal treatment in mandibular premolars.

METHODSA total of 2015 patients who underwent dental treatment and had full mouth periapical radiographs at the Peking University School of Stomatology from April 2011 to April 2012 were enrolled in this study. Three experienced dentists reviewed the patients' periapical films and classified the root morphology of mandibular premolars bilaterally. The incidence of unilateral and bilateral double roots were recorded and calculated, including confirmed and suspected bucco-lingual root types.

RESULTSIn terms of the morphology of two-rooted mandibular first premolars, of the 2015 cases with complete root formation, two-rooted first premolars were detected in 120 cases, with a total number of 159 teeth. According to the number of teeth, the overall incidence of double roots was 4.03% (159/3972). In terms of the morphology of two-rooted mandibular second premolars, of the 2015 cases with complete root formation, two-rooted second premolars were detected in 24 cases, with a total number of 33 teeth. According to the number of teeth, the overall incidence of double roots was 0.85% (33/3880).

CONCLUSIONSThe roots of mandibular premolars display specific morphological patterns. Based on a large sample, we observed and calculated not only the occurrence rate of bucco-lingual and mesio-distal double roots in first and second mandibular premolars, but also the incidence of unilateral or bilateral double roots within the same mandible. These findings could provide useful information on the anatomical structure of mandibular premolars for endodontic, prosthodontic and surgical procedures, and could improve the quality of treatment and reduce complications.
