Objective:To construct a prognostic model of hepatocellular carcinoma (HCC) with differential expression of autophagy genes.Method:Autophagy genes expression data of HCC and normal liver tissues were obtained from The Cancer Genome Atlas (TCGA) database and The Genotype-Tissue Expression (GTEx) database respectively. The gene expression data from different platforms is normalized into log 2(FPKM value + 1). Differentially expressed autophagy-related genes of HCC were identified by using R program limma package from the TCGA-GTEx combined data set, the criteria of |logFC| > 1 and FDR < 0.05 was deemed to be of statistically significance. The Gene Ontology (GO) analyses and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed by using R program clusterProfiler package, as criteria of P<0.05. Univariate and multivariate Cox proportional hazards regression analyses were performed by using R program survival package to identify the HCC potential prognostic differentially expressed autophagy-related genes. Furthermore, the statistically significant ( P<0.05) autophagy genes in the univariate Cox regression analysis were included in the multivariate Cox regression analysis, and the expression of each differentially expressed autophagy gene and the corresponding regression coefficient coef value based on this, the autophagy gene prognosis model of HCC was constructed: expmRNA1×βmRNA1+ expmRNA2×βmRNA2+ …+ expmRNAn×βmRNAn (exp: gene expression level; β: regression coefficient coef of multivariate Cox regression analysis). Draw the receiver operating characteristic (ROC) curve of the predictive model and calculate the area under curve (AUC) to evaluate the predictive value of the model. Results:The genes expression data and clinical information of 374 HCC samples and 160 normal liver tissue samples were obtained from TCGA and GTEx databases. Total 205 autophagy genes expression data was obtained from the TCGA-GTEx combined sequence. Among them, SPNS1, DIRAS3, TMEM74, NRG2, NRG1, IRGM, IKBKE, NKX2-3, BIRC5, CDKN2A, TP73 are differentially expressed autophagy genes that meet the screening criteria. GO analysis mainly enriched in "regulation of protein serine/threonine kinase activity" , "ErbB 2 signaling pathway" , "protein kinase regulator activity" and "kinase regulator activity" ; KEGG analysis enriched frequently in "EGFR tyrosine kinase inhibitor resistance" , "Hippo signaling pathway" . After integrating and deleting samples with missing survival information, a total of 418 sample expressions were included in the Cox regression analysis. After univariate and multivariate Cox risk regression analysis, the two autophagy genes NRG1 ( HR=1.5565, 95% CI: 1.1793-2.0543) and IKBKE ( HR=1.7502, 95% CI: 1.2093-2.5330) were screened out and a prognostic prediction model was established: (0.44247 × NRG1 expression level) + (0.55977 × IKBKE expression level). The ROC of the prognosis model shows that the AUC of the overall seven-year survival is 0.711. Conclusion:The prognosis model of HCC based on NRG1 and IKBKE has high predictive value for the long-term survival rate of hepatocellular carcinoma patients.

Objective To research the endometrial receptivity by established the endometriosis rat model in intimal window period.Methods The autologous endometrial tissues of 22 sexually mature SD rats were transplanted into the homonymy abdomi-nal wall and offside uterine mesometrium.After four weeks,we randomly dissected two rats and observed the growth of etopic en-dometrium.The EMs rats were mated with male rats in the same cage and vaginal plug was observed in the next day.The histomor-phology of eutopic and ectopic endometrial was observed in the fifth day of pregnancy.Results Ectopic endometrium was grown in the abdominal wall and mesometrium,which formed a small bulge cystic mass in 20 rats.All foci was showed adhesion to the sur-rounding tissues in a different extent.In the light microscope,the morphology of ectopic endometrial was as the same as nomal en-dometrium.The establishment of the endometriosis rat mode is successful.Vaginal plug was positive the next day.Nonoperative side uterine was full of fluid in the fifth day of pregnancy.Eutopic and ectopic endometrium were in the secretory phase..Conclusion It is a successful method to establish a rat model of endometriosis by autotransplantion of endometrium.The endometrium of EMs model rats is in embryo implantation window period,and it provides a convenient model for studying endometrial receptivity.

Objective To evaluate the effect of alveolar recruitment maneuver on the perioperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.Methods Forty morbidly obese patients of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 18-64 yr,with body mass index ≥ 40 kg/m2,scheduled for elective laparoscopic sleeve gastrectomy,were randomly divided into either control group (group C) or alveolar recruitment maneuver group (group R) using a random number table,with 20 patients in each group.Patients in group C were treated with volume-or pressure-controlled ventilation after creation of pneumoperitoneum,maintaining the peak inspiratory pressure (Ppeak) ≤ 30 cmH2O and partial pressure of end-tidal CO2 35-40 mmHg.Patients in group R received alveolar recruitment maneuver once every 30 min starting from creation of pneumoperitoneum until the end of surgery.Patients were transfered to post-anesthesia care unit (PACU) with endotracheal tube which was extubated when the unified extubation standard was achieved in PACU.The patients who stayed in PACU for 2 h showing no indications for extubation were transfered to intensive care unit for continuous ventilation support.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,and at the end of pneumoperitoneum,blood samples were collected from the radial artery for blood gas analysis.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak,plateau pressure (Peat),and dynamic lung compliance were recorded.The time for achieving extubation standard and time for achieving the standard for discharge from PACU were recorded.Patients were followed up until discharge,and the feeding time and duration of hospital stay were recorded.Results Compared with group C,PaO2 and oxygenation index were significantly increased at 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak was decreased at 60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,Pplat was decreased at 60 and 90 min of pneumoperitoneum,the dynamic lung compliance was increased at 30,60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,and the time for achieving extubation standard,time for achieving the standard for discharge from PACU,feeding time,and duration of hospital stay were shortened in group R (P＜0.05 or 0.01).In group C,one patient did not present with indications for extubation and were transfered to intensive care unit for continuous ventilation support.Conclusion Intraoperative alveolar recruitment maneuver can effectively improve the intraoperative pulmonary function and promote the recovery of postoperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.
