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.

OBJECTIVE:To discuss the problem lies in the orientation of clinical pharmacy of medical university.METHODS:The differences between traditional pharmacy education and clinical pharmacy in orientation were discussed,and reasonable proposals based on the practical situation of our country are given.RESULTS & CONCLUSION:Renovations of clinical pharmacy education should be conducted from aspects of orientation of subject,teaching model,curriculum arrangement,mechanism of practice etc.The orientation of clinical pharmacy is to train applied talents who can offer patient-centered pharmaceutical care and appropriately direct rational clinical drug administration.

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: Surfactant protein A (SP-A) is protein that appears to play an important role in mammalian first-line host defense. The objective of this study was to immunolocalize SP-A in human sinonasal tissue. Method:Eleven cases of allergic rhinitis, fifteen cases of polyp and seven cases of normal middle turbinate were studied with immunohistochemistry and immunofluorescence method to detect the expression of SP-A. Result:The expression of SP-A in allergic rhinitis and polyp were dramatically higher than that in controls(P<0.05), and there was no remarkable difference in the expression of SP-A between allergic rhinitis and polyp(P>0.05). The result demonstrated that SP-A was positivly correlated with eosinophils within the basement membrane of epitheli-um(R=0.81,0.55). In the result of immunofluorescence, there was significantly higher expression SP-A in nasal mucosa of allergic rhinitis and nasal polyp than that in control group(P<0.05). Conclusion:SP-A is likely to play key roles in the inflammatory reaction process of allergic rhinitis and polyp. Its secretion in the upper airway indicates that future studies may allow manipulation of this protein and development of novel treatments for sinonasal pathology.

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.

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.

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

AIM: This study was conducted to evaluate the bone repairing ability of coral artificial bone(CAB) composite of human recombinant bone morphogenetic protein-2(rhBMP-2-CAB) implanted into extraction sockets. METHODS: 12 adult dogs served as the experimental animals. Immediately after extraction of the upper second and third incisors, rhBMP-2-CAB and CAB were respectively implanted into each site of extraction sockets. The bone repairing ability of the two grafts was analyzed with histology, image analysis system and radionuclide bone imagining at 4th, 8th and 12th week, respectively. RESULTS: rhBMP-2-CAB were absorbed gradually after implanted into alveolar bone defect and were replaced completely by bone at 12 weeks. The ratio of new bone formation of rhBMP-2-CAB was significantly higher than that of CAB at different time( P
