Esophageal squamous cell carcinoma (ESCC) is a kind of malignant tumor with high incidence and mortality in the digestive system. The aim of this study is to explore the function of lnc-ABCA12-3 in the development of ESCC and its unique mechanisms. RT-PCR was applied to detect gene transcription levels in tissues or cell lines like TE-1, EC9706, and HEEC cells. Western blot was conducted to identify protein expression levels of mitochondrial apoptosis and toll-like receptor 4 (TLR4)uclear factor kappa-B (NF-κB) signaling pathway. CCK-8 and EdU assays were carried out to measure cell proliferation, and cell apoptosis was examined by flow cytometry. ELISA was used for checking the changes in glycolysis-related indicators.Lnc-ABCA12-3 was highly expressed in ESCC tissues and cells, which preferred it to be a candidate target. The TE-1 and EC9706 cells proliferation and glycolysis were obviously inhibited with the downregulation of lnc-ABCA12-3, while apoptosis was promoted. TLR4 activator could largely reverse the apoptosis acceleration and relieved the proliferation and glycolysis suppression caused by lnc-ABCA12-3 downregulation. Moreover, the effect of lnc-ABCA12-3 on ESCC cells was actualized by activating the TLR4/NF-κB signaling pathway under the mediation of exosome. Taken together, the lnc-ABCA12-3 could promote the proliferation and glycolysis of ESCC, while repressing its apoptosis probably by regulating the TLR4/NF-κB signaling pathway under the mediation of exosome.

Objective:To study the clinical features and high-risk factors of early-onset sepsis (EOS) in extremely preterm and super preterm infants.Methods:Retrospective study.Clinical data of extremely preterm and super preterm infants with the gestational age < 32 weeks were obtained from the clinical database of breast milk quality improvement registration in the Woman′s Hospital of Nanjing Medical University between January 2019 and December 2019.EOS cases were enrolled in the EOS group, and the remaining were enrolled in the control group.Risk factors for EOS, distribution of pathogenic bacteria, clinical features, complications, and outcomes between groups were analyzed.Measurement data were compared between the independent sample t-test.Counting data between groups were compared by the Chi- square test, corrected Chi- square test or Fisher′ s exact test.Multivariable Logistic regression model was used to analyze the risk factors of EOS in extremely and super preterm infants. Results:A total of 347 eligible neonates were recruited, including 22 neonates with EOS and 325 neonates without EOS.The incidence rate of EOS was 6.3%.Multivariate Logistic regression analysis showed that cesarean delivery was the protective factor for EOS ( OR=0.277, 95% CI: 0.091-0.847); while maternal prenatal infection ( OR=2.750, 95% CI: 1.053-2.908), fetid amniotic fluid ( OR=3.878, 95% CI: 1.344-11.187), chorioamnionitis ( OR=4.363, 95% CI: 1.552-12.236) and intubation ( OR=3.883, 95% CI: 1.133-13.306) were risk factors for EOS.A total of 22 strains of pathogenic bacteria were cultured in the EOS group, including 14 strains (63.6%) of Gram-positive bacteria, 7 strains (31.8%) of Gram-negative bacteria and 1 strain (4.6%) of fungus.The acute respiratory distress syndrome (54.5%), poor peripheral circulation perfusion (54.5%), mental depression (50.0%), and procalcitonin>0.5 mg/L (40.9%) were the main clinical features of EOS.Compared with the control group, extremely preterm and super preterm infants with EOS had a significantly higher rate of septic shock, disseminated intravascular coagulation, severe intraventricular hemorrhage (≥Ⅲ), acute respiratory distress syndrome (ARDS), and bronchopulmonary dysplasia( χ2=36.696, 33.255, 13.534, 95.455 and 3.886, respectively; all P<0.05). Conclusions:Maternal perinatal infection, odor amniotic fluid, chorioamnionitis and delivery room tracheal intubation are high-risk factors for preterm and super preterm infants with EOS, which can be prevented by cesarean section.Gram-positive cocci are the main pathogenic bacteria of EOS.ARDS and poor peripheral circulation perfusion are the main clinical manifestations of EOS, which increase the occurrence of severe intracranial hemorrhage and other complications.

Objective:To study the risk factors, cerebral hemodynamics and clinical outcomes of extremely and very preterm infants with severe intraventricular hemorrhage (IVH).Methods:From January 2019 to December 2019, premature infants with gestational age (GA) <32 w admitted to our hospital were assigned into severe IVH group and non-severe IVH group. Risk factors for severe IVH were analyzed. According to clinical outcomes, severe IVH group was further assigned into improvement subgroup and no-improvement subgroup. Cerebral hemodynamic parameters were compared between the two groups.Results:A total of 346 eligible neonates were enrolled in this study. The incidence of severe IVH was 11.0% (38 cases). The incidences of Grade Ⅲ and Ⅳ IVH were 8.7% (30/346) and 2.3% (8/346), respectively. Multivariate logistic regression analysis showed that CA < 28 w ( OR=4.365, 95% CI 1.055~18.054), 5 min Apgar score ≤7 ( OR=8.749, 95% CI 2.214~36.042), chorioamnionitis ( OR=3.245, 95% CI 1.127～9.344), PaCO 2 fluctuation within 1 h >25 mmHg ( OR=7.728, 95% CI 1.738~80.907) and vasoactive drugs usage ( OR=10.883, 95% CI 3.746~31.621) were the risk factors of severe IVH. 20 cases in severe IVH group were improved at discharge and 12 cases showed no improvement at discharge. Improvement subgroup showed quicker reduction of the middle cerebral artery flow resistance and faster recovery of the mean flow velocity than the no-improvement subgroup. Conclusions:GA <28 w, 5 min Apgar score ≤7, chorioamnionitis, PaCO 2 fluctuation within 1 h >25 mmHg and vasoactive drugs usage are risk factors of severe IVH in extremely and very preterm infants. Cerebral hemodynamic monitoring may provide initial assessment for the clinical outcomes for severe IVH.

Objective To analyze the correlation between intestinal flora changes and neonatal necrotizing enterocolitis (NEC)through 16S rRNA metagenomic sequencing and bacterial culture. Methods From September 2018 to March 2019, 10 NEC cases and 6 controls were randomly selected in the neonatal ICU ward of Nanjing maternal and child health care hospital to analyze the 16S rRNA metagenomic diversity of the for intestinal flora. The fecal samples and corresponding environmental samples were corrected from 51 cases of NEC children and their case controls to isolate and culture Clostridium. Results The dispersion of samples within the case group was smaller than that of the control group, and the sample diversity was higher than that of the control group. In the isolation and culture of Clostridium, the overall detection rate of Clostridium in the case group was 43.14% (22/51), and the detection rate of Clostridium butyricum was the highest (19.61%, 10/51). There was a statistical difference between the two groups (χ²=5.85, P=0.015 58). All Clostridium strains did not carry the A, B and E type neurotoxin genes. Conclusion: Increased intestinal flora diversity, intestinal flora abundance and changes in the abundance of Clostridium may be closely related to the intestinal environment of children with NEC; Clostridium, especially Clostridium butyricum, may be related to the occurrence of NEC.

Objective: To investigate the clinicopathological features and treatment strategy of pseudomyxoma peritonei (PMP) of ex-tra-appendiceal origin. Methods: Clinical data of 34 patients diagnosed with PMP of extra-appendiceal origin who were treated by cy-toreduction surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in the Aerospace Center Hospital from September 2011 to February 2019 were retrospectively analyzed. Clinical and imaging features were summarized and the Log-rank test was used for survival analysis. Results: The clinical manifestations of the 34 patients with PMP of extra-appendiceal origin were mainly abdomi-nal distension (58.8%) and abdominal pelvic mass (52.9%), which are very similar to those of appendiceal PMP. The incidence of main complications after CRS and HIPEC was 14.7%. During the follow-up period of a median of 12 months (range 1-46 months), 9 patients died, and the 1-and 3-year overall survival rates were 69.6% and 53.5%, respectively. In the univariate analysis, peritoneal cancer in-dex (PCI)>20, no HIPEC, and non-radical surgery were significant risk factors for poor prognosis, while gender, age, origin, and patho-logical type did not show significant correlations. Conclusions: The clinical features of PMP of extra-appendiceal origin are not differ-ent to those of PMP originating from the appendix. It is difficult to ascertain the primary lesion before the operation; however, regard-less of the origin, CRS combined with HIPEC is always a safe and effective treatment choice.

Objective To observe the usage of antiasthmatic drugs and seek problems of following the guidelines of asthma and COPD prevention & treatment in community hospitals.Methods The prescribed quantity in 2013 of antiasthmatic drugs was recorded for 5 community hospitals in a district of Shanghai.Basing on the defined daily dose (DDD),the dosing frequency of drugs (DDDs) and the percentages of each category of drugs were calculated.Then comparisons were made with the data of a grade Ⅱ hospital and a grade Ⅲ hospital in the same district.Results Among three level hospitals,no significant difference existed in the percentages of oral antiasthmatic drugs.But the major category of oral drugs at grades Ⅱ-Ⅲ hospitals was leukotriene receptor antagonist whereas only oral theophylline and oral β2-receptor agonists were available at community hospitals.Among inhaled drugs,inhaled corticosteroids (ICS) dominated at grades Ⅱ-Ⅲ hospitals.But at community hospitals,inhaled short-acting beta-agonists (SABA) predominated.Among inhalants,dry powder inhaler (DPI) dominated at grades Ⅱ-Ⅲ hospitals and metered dose inhaler (MDI) at community hospitals.Conclusions The usage of antiasthmatics at community hospitals is not consistent with the guidelines.Optimizing drug purchasing at hospitals,strengthening continued medical education,modifying the medication concept of patients and boosting the production of domestic inhalants should be urgently undertaken.

OBJECTIVE: To explore the clinical effect of ultrasound guided microwave ablation in the treatment 01 recurrent thyroid nodules. METHOD: Seventy-five cases of recurrent thyroid nodules were treated with ultrasound guided microwave ablation(MWA) under local anesthesia. All the patients underwent biopsy puncture, then the microwave ablation needle puncted in the center site of nodule with energy of 25-35 W, and the center tempera- ture could reach to 70-95 °C. RESULT: MWA were successfully performed in all the patients without significant com- plications. Temporary hoarseness occurred in 5 cases and dispeared after 1-3 weeks, choking water occurred in 2 patients and recovered 3-5 days later. Ultrasound examination showed that the bloodstream of thyroid nodules disappeared in all the patients, and the nodules diminuted with varying degrees at 3-month and at 6-month follow- up Serum FT4 and TSH did not change significantly. CONCLUSION Ultrasound guided MWA could be effective in the treatment of recurrent thyroid nodule with minimal invasive technology.
