Abstract
Acute respiratory distress syndrome (ARDS) continues to cause significant morbidity and mortality worldwide. However, there are currently no corresponding specific medications. Lung, right heart, and diaphragm protective therapy is the cornerstone of ARDS management. Non-invasive, radiation-free, and transportation-free point-of-care ultrasound enables for real-time dynamic evaluation of the lung, right heart, and diaphragm. It is an essential tool for the diagnosis, monitoring, and clinical decision-making of ARDS patients. However, ultrasound has several limitations, and its clinical application must be carefully evaluated in conjunction with clinical symptoms and other monitoring techniques. Further research is needed to determine whether clinical decision-making based on point-of-care ultrasound examination can improve the prognosis of ARDS patients.

Abstract
Objective: To investigate the diagnostic value of lung ultrasound in hospitalized children with community-acquired pneumonia (CAP). Methods: In the cross-sectional study, a total of 422 children with CAP who were hospitalized in the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, from February 2021 to August 2022 and completed lung ultrasound examination within 48 hours after admission were enrolled. The clinical characteristics, lung ultrasound and chest CT were collected. The patients were divided into two groups according to the signs of pneumonia indicated by chest CT, and the signs of lung ultrasound with diagnostic value were screened according to the signs of pneumonia indicated by chest CT by least absolute shrinkage and selection operator (Lasso) regression. According to severity of the disease, the children were divided into the severe group and the mild group, and the differences of lung ultrasound signs between the two groups were compared. Kruskal-Wallis test, Fisher's exact test was selected for comparison between groups. Random forest classifier wes used to evaluate the value of lung ultrasound in the diagnosis of CAP and prediction of severe pneumonia in children. The receiver operating characteristic curve was used to evaluate the prediction effect. Use DeLong test to compare the area under the curve. Results: Among the 422 cases of CAP, there were 258 males and 164 females, and the age of onset was 2.8 (1.3, 4.3) years. The confluent B-line, consolidation and pleural effusion detected by lung ultrasound were 309 cases (73.2%), 232 cases (55.0%) and 16 cases (3.8%), respectively, and the size of consolidation was 3.0 (0, 11.0) mm. One hundred and ten children (26.1%) with CAP completed chest CT. There were 90 cases with signs of pneumonia in chest CT and 20 cases without signs of pneumonia. Lasso was used for feature selection.Lung consolidation (OR=2.46), bilateral lung consolidation (OR=1.16) and confluent B-line (OR=1.34) were the main index. With random forest classifier, the accuracy of models using full variables and Lasso-selected variables were 0.79 (95%CI 0.70-0.86) and 0.79 (95%CI 0.70-0.86), the sensitivity were 0.81 and 0.81, and the specificity were 0.75 and 0.70, and the area under curve were 0.87 (95%CI 0.81-0.94, P<0.001) and 0.84 (95%CI 0.76-0.91, P<0.001), respectively. There were 97 cases in severe group and 325 cases in mild group. Compared with the mild group, the detection rate of consolidation, multiple consolidation, the size of consolidation and the size of consolidation was adjusted by body surface area (consolidation size/body surface area) in severe group were higher (66 cases (68.0%) vs. 166 cases (51.1%), 42 cases (43.3%) vs. 93 cases (28.6%), 8.0 (0, 17.0) vs. 1.0 (0, 9.0) mm, 12.5 (0, 24.6) vs. 2.1 (0, 17.6), χ2=8.59, 9.98, Z=14.40, 12.79, all P<0.05). Using lung ultrasound lung consolidation size and consolidation size/body surface area to predict the severe CAP, the optimal cut-off value were 6.7 mm and 10.2, the accuracy was 0.80 (95%CI 0.75-0.83) and 0.89 (95%CI 0.86-0.92), the sensitivity was 0.99 and 0.99, the specificity was 0.14 and 0.56, respectively, and the area under the curve was 0.66 (95%CI 0.60-0.72, P<0.001) and 0.76 (95%CI 0.70-0.83, P<0.001), respectively. The area under the curve of consolidation size/body surface area was higher than that of consolidation size (Z=5.50, P<0.001). Conclusions: Consolidation and confluent B-line, are important index for lung ultrasound diagnosis of CAP in children. The actual consolidation size adjusted by body surface area is superior to the size of consolidation in predicting severe CAP.

Abstract
Objective: To analyze the status of respiratory pathogen detection and the clinical features in children with Mycoplasma pneumoniae pneumonia (MPP). Methods: A prospective, multicenter study was conducted to collect clinical data, including medical history, laboratory examinations and multiplex PCR tests of children diagnosed with MPP from 4 hospitals in China between November 15th and December 20th, 2023. The multiplex PCR results and clinical characteristics of MPP children in different regions were analyzed. The children were divided into severe and mild groups according to the severity of the disease. Patients in the severe group were further divided into Mycoplasma pneumoniae (MP) alone and Multi-pathogen co-detection groups based on whether other pathogens were detected besides MP, to analyze the influence of respiratory pathogen co-detection rate on the severity of the disease. Mann-Whitney rank sum test and Chi-square test were used to compare data between independent groups. Results: A total of 298 children, 136 males and 162 females, were enrolled in this study, including 204 children in the severe group with an onset age of 7.0 (6.0, 8.0) years, and 94 children in the mild group with an onset age of 6.5 (4.0, 7.8) years. The level of C-reactive protein, D-dimer, lactic dehydrogenase (LDH) were significantly higher (10.0 (5.0, 18.0) vs. 5.0 (5.0, 7.5) mg/L, 0.6 (0.4, 1.1) vs. 0.5 (0.3, 0.6) mg/L, 337 (286, 431) vs. 314 (271, 393) U/L, Z=2.02, 2.50, 3.05, all P<0.05), and the length of hospitalization was significantly longer in the severe group compared with those in mild group (6.0 (6.0, 7.0) vs. 5.0 (4.0, 6.0) d, Z=4.37, P<0.05). The time from onset to admission in severe MPP children was significantly shorter than that in mild MPP children (6.0 (5.0, 9.5) vs. 9.0 (7.0, 13.0) d, Z=2.23, P=0.026). All patients completed the multiplex PCR test, with 142 cases (47.7%) MPP children detected with 21 pathogens including adenovirus 25 cases (8.4%), human coronavirus 23 cases (7.7%), rhinovirus 21 cases (7.0%), Streptococcus pneumoniae 21 cases (7.0%), influenza A virus 18 cases (6.0%). The pathogens with the highest detection rates in Tianjin, Shanghai, Wenzhou and Chengdu were Staphylococcus aureus at 10.7% (8/75), adenovirus at 13.0% (10/77), adenovirus at 15.3% (9/59), and both rhinovirus and Haemophilus influenzae at 11.5% (10/87) each. The multi-pathogen co-detection rate in severe MPP children was significantly higher than that in mild MPP group (52.9% (108/204) vs. 36.2% (34/94), χ²=10.62,P=0.005). Among severe MPP children, there are 89 cases in the multi-pathogen co-detection group and 73 cases in the simple MPP group. The levels of LDH, D-dimer and neutrophil counts in the multi-pathogen co-detection group were significantly higher than those in the simple MPP group (348 (284, 422) vs. 307 (270, 358) U/L, 0.8 (0.5, 1.5) vs. 0.6 (0.4, 1.0) mg/L, 4.99 (3.66, 6.89)×109 vs. 4.06 (2.91, 5.65)×109/L, Z=5.17, 4.99, 6.11, all P<0.05). Conclusions: The co-detection rate of respiratory pathogens, LDH and D-dimer in children with severe MPP were higher than those with mild MPP. Among severe MPP children the stress response of children in co-detection group was more serious than that of children with simple MPP.

Abstract
Objective: To explore the molecular mechanism of circDDX17 regulating the proliferation and apoptosis of non-small cell lung cancer cells by targeting the miR-223-3p/RIP3 molecular axis. Methods: The expression levels of circDDX17, miR-223-3p, and RIP3 in human normal lung epithelial cell lines BEAS-2B and non-small cell lung cancer cells H1299, A549, and H446 were detected by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR). The plasmids of pcDNA, pcDNA-circDDX17, anti-miR-con, anti-miR-223-3p, pcDNA-circDDX17 and miR-con, pcDNA-circDDX17 and miR-223-3p mimics were transfected into H1299 cells. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide (MTT) assay was used to detect the cell proliferation. Flow cytometry was used to detect the cell cycle and cell apoptosis. Plate cloning experiment was used to detect cell proliferation ability. The dual luciferase report experiment was applied to verify the targeting relationship between miR-223-3p with circDDX17 and RIP3. Western blot was used to detect the protein expression of cyclinD1, CDK2, cleaved caspase-3 and Bax. Results: The expression levels of circDDX17 and RIP3 mRNA in H1299, A549, and H446 cells were significantly reduced (P<0.05), the expression level of miR-223-3p mRNA was significantly increased (P<0.05) compared with BEAS-2B. The cell viability [(69.46±4.68)%], the number of cell clones (83.49±7.86), the proportion of cells in S phase [(22.52±1.41) %], the protein expression levels of cyclinD1 and CDK2 in PCDNa-CircDDX17 group were lower than those in pcDNA group [(97.54±7.72)%, 205.03±13.37, (28.69±1.49)%, respectively, P<0.05], while the percentage of G0/G1 phase cells [(64.45±3.56)%], apoptosis rate [(18.36±1.63)%], the protein expression levels of cleaved caspase-3 and Bax in pcDNA-circDDX17 group were higher than those of pcDNA group [(51.33±2.76) % and (5.21±0.54) %, respectively, P<0.05]. The viability [(72.64±5.44)%], the number of cell clones (78.16±8.23), the proportion of S-stage cells [(21.34±1.59) %], the protein expression levels of CyclinD1 and CDK2 in anti-miR-223-3p group were lower than those in anti-miR-con group [(103.47±6.25)%, 169.32±14.53, (28.43±1.26)%, respectively, P<0.05]. Percentage of G0/G1 phase cells [(62.86±3.28)%], apoptosis rate [(14.64±1.67)%], the protein expression levels of cleaved caspase-3 and Bax in the anti-miR-223-3p group were higher than those of anti-miR-con group [(51.33±2.71)% and (4.83±0.39)%, respectively, P<0.05]. MiR-223-3p has complementary sites with circDDX17 or RIP3. The viability [(135.45±9.28)%], the number of cell clones (174.64±10.68), the proportion of S-phase cells [(26.39±2.25)%], the protein expression levels of cyclinD1 and CDK2 in pcDNA-circDDX17+miR-223-3p group were higher than those in pcDNA-circDDX17+miR-con group [(101.56±6.68)%, 107.65±7.62, (21.64±1.72)%, P<0.05]. Percentage of G0/G1 phase cells [(56.64±2.76)%], apoptosis rate [(8.34±0.76)%], the protein expression levels of cleaved caspase-3 and Bax in pcDNA-circDDX17+miR-223-3p group were lower than those of pcDNA-circDDX17+miR-con group [(64.03±3.48)% and (15.21±1.18)%, respectively, P<0.05]. Conclusion: circDDX17 could inhibit the proliferation and induce apoptosis of non-small cell lung cancer cells via targeting the miR-223-3p / RIP3 molecular axis.

Abstract
Objective: The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach. Methods: Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis. Results: A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score (r = 0.47, P = 0.002), albumin-bilirubin score (r = 0.37, P = 0.001), Lok index (r = 0.36, P = 0.02), liver stiffness (r = 0.58, P = 0.01), and spleen stiffness (r = 0.77, P = 0.01), while negatively correlated with albumin (r = -0.42, P = 0.006). Conclusion: The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Abstract
Objective: To investigate the clinical characteristics and maternal and fetal prognosis of pregnant women with acute fatty liver of pregnancy (AFLP). Methods: The clinical data of 86 AFLP pregnant women admitted to the Third Affiliated Hospital of Guangzhou Medical University from September 2017 to August 2022 were collected, and their general data, clinical characteristics, laboratory tests and maternal and fetal outcomes were retrospectively analyzed. Results: (1) General information: the age of the 86 pregnant women with AFLP was (30.8±5.4) years, and the body mass index was (21.0±2.5) kg/m2. There were 50 primiparas (58.1%, 50/86) and 36 multiparas (41.9%, 36/86). There were 64 singleton pregnancies (74.4%, 64/86) and 22 twin pregnancies (25.6%, 22/86). (2) Clinical characteristics: the main complaints of AFLP pregnant women were gastrointestinal symptoms, including epigastric pain (68.6%, 59/86), nausea (47.7%, 41/86), anorexia (46.5%, 40/86), vomiting (39.5%, 34/86). The main non-gastrointestinal symptoms were jaundice of skin and/or scleral (54.7%, 47/86), edema (38.4%, 33/86), fatigue (19.8%, 17/86), bleeding tendency (16.3%, 14/86), polydipsia or polyuria (14.0%, 12/86), skin itching (8.1%, 7/86), and 17.4% (15/86) AFLP pregnant women had no obvious symptoms. (3) Laboratory tests: the incidence of liver and kidney dysfunction and abnormal coagulation function in AFLP pregnant women was high, and the levels of blood ammonia, lactate dehydrogenase and lactic acid were increased, and the levels of hemoglobin, platelet and albumin decreased. However, only 24 cases (27.9%, 24/86) of AFLP pregnant women showed fatty liver by imageology examination. (4) Pregnancy outcomes: ① AFLP pregnant women had a high incidence of pregnancy complications, mainly including renal insufficiency (95.3%, 82/86), preterm birth (46.5%, 40/86), hypertensive disorders in pregnancy (30.2%, 26/86), gestational diabetes mellitus (36.0%, 31/86), fetal distress (24.4%, 21/86), pulmonary infection (23.3%, 20/86), disseminated intravascular coagulation (16.3%, 14/86), multiple organ dysfunction syndrome (16.3%, 14/86), hepatic encephalopathy (9.3%, 8/86), and intrauterine fetal death (2.3%, 2/86). ② Treatment and outcome of AFLP pregnant women: the intensive care unit transfer rate of AFLP pregnant women was 66.3% (57/86). 82 cases were improved and discharged after treatment, 2 cases were transferred to other hospitals for follow-up treatment, and 2 cases (2.3%, 2/86) died. ③ Neonatal outcomes: except for 2 cases of intrauterine death, a total of 106 neonates were delivered, including 39 cases (36.8%, 39/106) of neonatal asphyxia, 63 cases (59.4%, 63/106) of neonatal intensive care unit admission, and 3 cases (2.8%, 3/106) of neonatal death. Conclusions: AFLP is a severe obstetric complication, which is harmful to mother and fetus. In the process of clinical diagnosis and treatment, attention should be paid to the clinical manifestations and laboratory tests of pregnant women, early diagnosis and active treatment, so as to improve maternal and fetal outcomes.

Abstract
Objective: To study the diagnostic value of lipoprotein-associated phospholipase A2(LP-PL-A2) in occult pancreaticobiliary reflux(OPBR) combined with gallbladder cholesterol deposition. Methods: This was a case-control study. Forty-six patients with OPBR who underwent gallbladder surgery at Shanghai East Hospital from December 2020 to October 2021, with gallbladder cholesterol deposition as the case group and the remainder as the control group, were included for analysis of their clinical data. Results: There were 21 cases in the case group, with 10 males and 11 females, and aged (57±12) years; 25 cases in the control group, with 11 males and 14 females, and aged (56±10) years. Serum LP-PL-A2 [(551.62±128.69) U/L] was significantly higher in the case group than in the control group [(436.70±135.88) U/L] (t=-2.80,P<0.01).Univariate analysis showed that LP-PL-A2 was a risk factor for OPBR combined with gallbladder cholesterol deposition, OR(95%CI):1.007(1.002-1.012), P=0.011. The area under the receiver operating characteristic curve (ROC) curve was 0.742, P=0.005. Conclusion: LP-PL-A2 is of diagnostic value in OPBR combined with gallbladder cholesterol deposition.

Abstract
Objective: To explore the association between gallbladder adenomyomatosis (GA) and occult pancreaticobiliary reflux (OPBR). Methods: A total of 81 patients with GA who underwent cholecystectomy in Shanghai East Hospital from December 2020 to January 2022 were enrolled, including 48 cases of fundal type, 28 cases of segmental type and 5 cases of diffuse type. Patient's intraoperative bile was coltected and tested for amylase. According to gallbladder bile amylase level, patients were divided into OPBR group (bile amylase>110 U/L) and the control group (bile amylase≤110 U/L). Results: Among 81 patients, 32 were male and 49 were female, and aged (49.1±13.2) years; there were 66 cases in control group, including 27 males and 39 females, and aged (50.0±12.9)years; there were 15 patients in the OPBR group, including 5 males and 10 females, and aged (45.1±14.2) years. In terms of the clinical features of the two groups, there was no significant difference (all P>0.05), except for a significant increase in biliary amylase in the OPBR group compared with the control group (P<0.001). However, the incidence of OPBR was significantly different in the three types of GA, with a lower incidence of OPBR in the fundal type (10.4%, 5/48) than in the segmental type (28.6%, 8/28) and diffuse type (2/5) (P=0.038). In addition, segmental GA was more likely to be combined with gallbladder stones (85.7%, 24/28) than fundal GA (58.3%, 28/48) and diffuse GA (3/5) (P=0.031). Univariate and multivariate logistic regression analyses showed OPBR [OR (95%CI)=3.410 (1.010 to 11.513), P=0.048] and combined gallbladder stones [OR (95%CI)=2.974 (1.011 to 8.745), P=0.048] indepenclently correlated with segmental and diffuse GA. Conclusions: The incidence of OPBR is higher in segmental and diffuse GA, and gallstones and OPBR are independently associated with the occurrence of segmental and diffuse GA. These results suggest that OPBR may be the initiating factor for the occurrence and carcinogenesis of segmental and diffuse GA.

Abstract
Objective: To explore the relationship between DNA methylation and occupational noise-induced hearing loss. Methods: A case-control study was conducted. People with hearing loss induced by occupational noise were recruited as the case group and those with normal hearing but still exposed to occupational noise were recruited as the control group. A total of 60 participants were included, of which 30 participants were in the case group and 30 in the control group. The methylation level was detected by 850k genome-wide DNA methylation chip technology. The significance of differential methylated position (DMP) was tested by R-packet 'Champ'. The differential methylated region (DMR) was analyzed by using Champ's Bumphunter algorithm. Cluster profiler was used to analyze the gene list for GO and KEGG pathway enrichment. Results: There was significant difference between two groups in binaural high-frequency average hearing threshold (P<0.05), but there was no significant difference in age, smoking, drinking, hypertension, physical exercise and cumulative noise exposure. The results of DMP and DMR analysis showed that 713875 sites were detected in the case group and the control group, and 439 methylation sites with significant difference, accounting for 0.06%; 650 regions were detected, and 72 methylation regions with significant differences, accounting for 11.08%. Compared with the control group, the results of GO enrichment analysis showed that the case group had statistically significant differences in four pathways: axogenesis of projection neurons in the central nervous system, neuronal development in the central nervous system, axogenesis of neurons in the central nervous system and neuronal differentiation in the central nervous system. KEGG enrichment analysis showed that there were significant differences in sphingolipid metabolism, aldosterone synthesis and secretion, primary bile acid biosynthesis pathway between the case group and the control group. Conclusion: The occurrence of occupational noise-induced hearing loss may be related to the regulation of gene expression related to axogenesis of projection neurons in the central nervous system, development of neurons in the central nervous system, axogenesis of neurons in the central nervous system, differentiation of neurons in the central nervous system, sphingolipid metabolism, aldosterone synthesis and secretion, primary bile acid biosynthesis and gene methylation related to metabolism.

Abstract
Sepsis is a critical medical problem that needs to be solved urgently worldwide. Some patients with sepsis have refractory shock or/and severe respiratory failure, which may require supporting with extracorporeal membrane oxygenation (ECMO). Particularly, it is important to choose the optimal mode and grasp the optimal timing of the initiation in the experienced ECMO center. The choice of mode is mainly based on the patient's condition of oxygenation and hemodynamics. During the management of ECMO support, some issues like blood flow, anticoagulation and therapy of antibiotics should be noted. Thus far, the research of ECMO in adult patients with sepsis and septic shock are mainly retrospective, observational and with small sample size. Further exploration is needed in the future.

Abstract
Dihydromyricetin has shown many bioactivities in cell level. However, dihydromyricetin was found to be highly instable in cell culture medium DMEM. Here, the underlying degradation mechanism was investigated via UPLC-MS/MS analysis. Dihydromyricetin was mainly converted into its dimers and oxidized products. At lower temperature, dihydromyricetin in DMEM showed higher stability. Vitamin C increased the stability of dihydromyricetin in DMEM probably due to its high antioxidant potential.

Abstract
Objective: To explore the classification and reconstruction strategy of defects in lateral face region after operation of malignant tumors. Methods: Eighteen cases with the reconstruction of complicated defects after resection of tumors in the region of lateral face from January 2015 to January 2018 in Hunan Cancer Hospital were retrospectively reviewed. There were 14 males and 4 females, aged from 32 to 68 years. According to the presence or absence of bony scaffold, complicated defects were divided into two main categories: soft tissue perforating defects and soft tissue defects combined with bony scaffold defects. All soft tissue perforating defects in 5 cases were repaired with free anterolateral femoral flaps. Among 13 cases with soft tissue plus bony scaffold defects, 3 were repaired with free fibular flaps, 6 with free fibular flaps combined with free anterolateral femoral flaps, and 4 with chimeric deep circumflex iliac artery perforator flaps combined with anterolateral femoral flaps. Results: All flaps survived well. Two patients complicated with fistula in floor of mouth, but the wound healed after dressing change. Transoral feeding was resumed within 2 weeks after surgery in all patients. One year follow-up evaluation showed that 14 cases had symmetrical face and 10 cases had mouth opening more than 3 transverse fingers. After 36-50 months of follow-up, 6 patients died, with an overall 3-year survival rate of 66.7%. Conclusion: The classification of defects with or without bony stent loss is conducive to the overall repair design, the recovery of facial contour stent, the effective fill of dead space and the maintain of residual occlusal relationship. Good reconstruction results require a multi flap combination of osteocutaneous and soft tissue flaps.

Abstract
Objective: To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL). Methods: A total of 557 patients from 2000-2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis. Results: The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 (P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population (P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy (P<0.001). Radiotherapy dose was an independent factor affecting LRC(P<0.05). Conclusions: Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.

Abstract
Objective: To analyze the application of Chronic Obstructive Pulmonary Disease (COPD) Screening Questionnaire and pulmonary function test in dust-exposed migrant workers. Methods: In May 2019, 149 cases of dust exposed migrant workers were selected as the research subjects through the free clinic in the countryside. COPD Screening Questionnaire and lung function test were carried out to analyze the high-risk groups and the influencing factors of positive pulmonary function test results. Results: Among 149 cases of dust-exposed migrant workers, 107 (71.8%) were positive for questionnaire screening, 73 (49.0%) were positive for pulmonary function test, 75 (50.3%) were diagnosed with coal worker's pneumoconiosis, and 101 (67.8%) were diagnosed with lung function injury. The positive rate of pulmonary function of migrant workers with positive questionnaire screening results was significantly higher than that of those with negative results (P<0.05) . The results of multivariate analysis showed that compared with non-pneumoconiosis, the risk of positive pulmonary function test results was higher in dust-exposed migrant workers with stage Ⅲ pneumoconiosis (OR=16.462, 95%CI: 3.390-79.946; P<0.01) . Compared with non-smoking, the risks of positive pulmonary function test results of dust-exposed migrant workers with smoking index of 11-20 package years and >20 package years were higher (OR=19.814, 95%CI: 3.854-101.883; OR=9.733, 95%CI: 2.310-41.008; P<0.01) . Conclusion: The risk of COPD in dust-exposed migrant workers is high, so we should strengthen the early examination of the high pneumoconiosis stage and smoking population. The screening questionnaire can better screen out the high-risk groups of COPD, and it can be used as a basic screening tool.

Abstract
Abstract Objective To study the growth regulation, environmental adaption and epigenetic regulation of Chrysomyia Megacephala pupae, in order to obtain the transcriptome data of Chrysomyia Megacephala in different growing periods, and lay the foundation for forensic application. Methods The Chrysomyia Megacephala was cultivated and after pupation, 3 pupae were collected every 24 h from pupation to emergence, and stored at -80 ℃ for later use. High-throughput sequencing was performed by Illumina Hiseq 4000 and Unigenes were obtained. The Unigenes were compared by comparison tool BLAST from NCBI in databases such as NR, STRING, SWISS-PROT (including Pfam), GO, COG, KEGG in order to obtain the corresponding annotation information. The expression amount of Unigenes obtained by sequencing in Chrysomyia Megacephala in six different growing periods was calculated by FPKM method, and the discrepant genes were screened according to the following standards: the log2 multiple absolute value of FPKM expression amount between two different growing periods must be larger than 1 (log2|FC|>1), and the false discovery rate must be less than 0.05. Results When the mean temperature was 25.6 ℃, Chrysomyia Megacephala emerged 6 d after they pupated. A total of 43 408 pieces of Unigenes were obtained and their mean length was 905 bp, of which 32 500, 18 720, 13 542, 9 191 and 18 720 pieces were annotated by NR, SWISS-PORT, Pfam, STRING and KEGG databases. According to the discrepant gene analysis of pupae in two different growing periods, the number of genes with variants ranged from 801 to 5 307, and the total number of discrepant genes was 45 676. Conclusion The gene expressions of the transcriptome data of Chrysomyia Megacephala pupae in different growing periods are different. The results provided a good foundation for further research on the transcriptome changes in each period of the pupae of sarcosaprophagous flies and provided the basis for exploring the genes associated with the growth of Chrysomyia Megacephala pupae.

Abstract
Objective: To study the expression of GATA3 and bcl-11b in peripheral T-cell lymphoma (PTCL) and their correlation with clinicopathological features. Methods: The Oncomine and GEO databases were used for analyzing the expression levels of GATA3 and bcl-11b mRNA in PTCL. Immunohistochemistry was used to detect the expression of GATA3 and bcl-11b proteins in 127 cases of PTCL diagnosed at Shanxi Provincial Cancer Hospital from January 2010 to June 2020, as well as 40 cases of lymph node with reactive hyperplasia. Results: The data in Oncomine and GEO databases showed that the expression of GATA3 and bcl-11b mRNA in PTCL was lower than that in normal tissues (P<0.05). Immunohistochemistry showed that the positive rates of GATA3 in PTCL and lymph nodes with reactive hyperplasia were 60.6% (77/127) and 85.0% (34/40, P<0.05), respectively. The expression rates of bcl-11b in PTCL and lymph nodes with reactive hyperplasia were 55.1% (70/127) and 75.0% (30/40, P<0.05), respectively. The expression of GATA3 was related to the pathological classification of the patients with PTCL, and was inversely related to the Ann Arbor stage of the patient, while the expression of bcl-11b was inversely correlated with the IPI score of the patient (P<0.05). The expression of GATA3 and bcl-11b was related to the patients' age, gender, LDH level, and B symptoms. Other clinicopathological characteristics were irrelevant. Spearman correlation analysis shows that the expression of GATA3 protein was associated with that of bcl-11b protein in PTCL. Conclusion: GATA3 and bcl-11b are closely related to the prognosis of PTCL, and may be important factors involved in the occurrence and development of PTCL.

Abstract
Objective: To investigate the etiology of necrotizing pneumonia (NP) in children and the clinical characteristics of NP caused by different pathogens in China. Methods: A retrospective, case-control study was performed in children with NP who were admitted to 13 hospitals in China from January 2008 to December 2019. The demographic and clinical information, laboratory data, etiological and radiological findings were analyzed. The data were divided into three groups based on the following years: 2008-2011, 2012-2015 and 2016-2019, and the distribution characteristics of the pathogens in different period were compared. Meanwhile, the pathogens of pediatric NP in the southern and northern China were compared. And the clinical characteristics of the Mycoplasma pneumoniae (MP) NP and the bacterial NP were also compared. T-test or Mann-Whitney nonparametric test was used for comparison of numerical variables, and χ2 test was used for categorical variables. Results: A total of 494 children with NP were enrolled, the median ages were 4.7 (0.1-15.3) years, including 272 boys and 222 girls. Among these patients, pathogens were identified in 347 cases and the pathogen was unclear in the remaining 147 cases. The main pathogens were MP (238 cases), Streptococcus pneumoniae (SP) (61 cases), Staphylococcus aureus (SA) (51 cases), Pseudomonas aeruginosa (13 cases), Haemophilus influenzae (10 cases), adenovirus (10 cases), and influenza virus A (7 cases), respectively. MP was the most common pathogen in all three periods and the proportion increased yearly. The proportion of MP in 2016-2019 was significantly higher than that in 2012-2015 (52.1% (197/378) vs. 36.8% (32/87), χ2=6.654, P=0.010), while there was no significant difference in the proportion of MP in 2012-2015 and that in 2008-2011 (36.8% (32/87) vs. 31.0% (9/29), χ²=0.314, P=0.575).Regarding the regional distribution, 342 cases were in the southern China and 152 in the northern China. Also, MP was the most common pathogen in both regions, but the proportion of MP was higher and the proportion of SP was lower in the north than those in the south (60.5% (92/152) vs. 42.7% (146/342), χ2=13.409, P<0.010; 7.9% (12/152) vs. 14.3% (49/342), χ2=4.023, P=0.045). Comparing the clinical characteristics of different pathogens, we found that fever and cough were the common symptoms in both single MP and single bacterial groups, but chest pain was more common (17.0% (34/200) vs. 6.1% (6/98), χ2=6.697, P=0.010) while shortness of breath and wheezing were less common in MP group (16.0% (32/200) vs. 60.2% (59/98), χ2=60.688, P<0.01; 4.5% (9/200) vs. 21.4% (21/98), χ2=20.819, P<0.01, respectively). The white blood cell count, C-reactive protein and procalcitonin in the bacterial group were significantly higher than those in the MP group (14.7 (1.0-67.1)×109/L vs. 10.5 (2.5-32.2)×109/L, 122.5 (0.5-277.3) mg/L vs. 51.4 (0.5-200.0) g/L, 2.13 (0.05-100.00) μg/L vs. 0.24 (0.01-18.85) μg/L, Z=-3.719, -5.901 and -7.765, all P<0.01). Conclusions: The prevalence of pediatric NP in China shows an increasing trend during the past years. MP, SP and SA are the main pathogens of NP, and the most common clinical symptoms are fever and cough. The WBC count, C-reactive protein and procalcitonin in bacterial NP are significantly higher than those caused by MP.

Abstract
Objective: To examine the correlation between neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and neutrophil-monocyte ratio (NMR) for postoperative pneumonia or long-term overall survival in patients with esophageal cancer after neoadjuvant therapy. Methods: The clinical data of 137 patients, including 111 males and 26 females, with the age of (M(QR))61(10) years (range: 45 to 75 years), undergoing radical resection of esophageal cancer after neoadjuvant therapy admitted at Department of Thoracic Surgery, West China Hospital from January 2016 to May 2019 were analyzed retrospectively. The blood routine one or two days before surgery and the occurrence of pneumonia after surgery were collected via hospital information system. The absolute count of neutrophils, lymphocytes and monocytes was recorded, to calculate NLR, LMR and NMR. The survival of patients was recorded systematically via follow-up. In the first part, the influencing factors of postoperative inflammation were analyzed, to group the patients into two groups according to the occurrence of postoperative pneumonia. χ2 test, t-test or rank-sum test were conducted for inter-group comparison. In the second part, cutoff values of inflammatory biomarkers were obtained with the receiver operating characteristic (ROC) curve and grouped, with postoperative pneumonia as endpoint criteria. Independent factors correlated with postoperative pneumonia were determined through univariate and multivariate Logistic regression analysis. In the third part, the analysis on prognosis factors was carried on, with the survival as endpoint criteria. Cutoff values of inflammatory biomarkers were obtained with X-Tile software and grouped. The survival analysis was carried on with univariate and multivariate Cox proportional hazards regression model, and the Kaplan-Meier curve was drawn finally. The results of survival analysis were verified by Log-rank test. Results: Median follow-up time was 614 (299) days (range: 382 to 1 612 days). Cutoff values of NLR, LMR, and NMR obtained via the ROC curve were 3.0, 3.9, and 6.2, respectively. According to the multivariate Logistic regression analysis, NLR>3.0 (OR=2.740, 95% CI: 1.221 to 6.152, P=0.015) and LMR>3.9 (OR=0.140, 95% CI: 0.022 to 0.890, P=0.037) were independent prognosis factors for postoperative pneumonia in patients with esophageal cancer after neoadjuvant therapy. Cutoff values of NLR, LMR, and NMR obtained with X-Tile software were 3.3, 4.2, and 7.2, respectively. Through multivariate Cox proportional risk regression analysis, late tumor ypTNM staging (8th AJCC) (HR=2.087, 95% CI:1.079 to 4.038, P=0.029), poor pathologic response (HR=2.251, 95% CI: 1.117 to 4.538, P=0.023), and LMR>4.2 (HR=0.347, 95% CI: 0.127 to 0.946, P=0.039) could be independent prognosis factors for overall survival. Kaplan-Meier survival analysis indicated that the overall survival of patients with LMR ≤4.2 was worse (P=0.002), with the 1-year overall survival rate of 82.9%, and the 1-year overall survival rate of patients with LMR>4.2 was 94.6%. Conclusion: Preoperative LMR ≤3.9 and NLR>3.0 can be considered as independent prognosis factors for postoperative pneumonia, while LMR≤4.2 as one of independent prognosis factors for overall survival.

Abstract
BACKGROUND This study evaluated the survival benefit of asparaginase (ASP)-based versus non-ASP-based chemotherapy combined with radiotherapy in a real-world cohort of patients with early-stage extranodal nasal-type natural killer/T-cell lymphoma (ENKTCL). PATIENTS AND METHODS We identified 376 patients who received combined radiotherapy with either ASP-based (ASP, platinum, and gemcitabine; n = 286) or non-ASP-based (platinum and gemcitabine; n = 90) regimens. The patients were stratified into low-, intermediate-, and high-risk groups using the early stage-adjusted nomogram-revised risk index. Overall survival (OS) and distant metastasis (DM)-free survival (DMFS) between the chemotherapy regimens were compared using inverse probability of treatment weighting (IPTW) and multivariable analyses. RESULTS ASP-based (versus non-ASP-based) regimens significantly improved 5-year OS (84.5% versus 73.2%, P = 0.021) and DMFS (84.4% versus 74.5%, P = 0.014) for intermediate- and high-risk patients, but not for low-risk patients in the setting of radiotherapy. Moreover, ASP-based regimens decreased DM, with a 5-year cumulative DM rate of 14.9% for ASP-based regimens compared with 25.1% (P = 0.014) for non-ASP-based regimens. The survival benefit of ASP-based chemotherapy and radiotherapy remained consistent after adjusting the confounding variables using IPTW and multivariate analyses; additional sensitivity analyses confirmed these results. CONCLUSIONS The findings provided support for ASP-based chemotherapy and radiotherapy as a first-line treatment strategy for intermediate- and high-risk early-stage ENKTCL.

Abstract
Objective: To investigate the clinical effects of retrograde anterolateral thigh perforator flaps assisted with computed tomography angiography (CTA) in repairing skin and soft tissue defects around the knee or in proximal lower leg. Methods: A retrospective cohort study was conducted. From May 2015 to October 2019, 17 patients with skin and soft tissue defects around the knee or in proximal lower leg were admitted to the Department of Orthopedics of Jizhong Energy Xingtai Mig General Hospital, including 12 males and 5 females, aged 16-65 years, with an average age of 35 years. The areas of skin and soft tissue defects after debridement ranged from 6.0 cm×3.0 cm to 15.0 cm×9.0 cm. The retrograde anterolateral thigh perforator flaps were designed according to the origin and distribution of the perforating branches in flaps and the length of the vascular pedicle examined with CTA and the condition of the wound to repair the wounds. The areas of resected flaps ranged from 6.5 cm×3.5 cm to 15.5 cm×9.5 cm. The wounds in donor sites of flaps were sutured directly or covered with medium-thickness skin grafts from healthy upper leg. The sources of the perforating branches in flaps were recorded. The lateral circumflex femoral artery, its branches, and the relative length of the vascular pedicle were compared between preoperative CTA detection and intraoperative observation. The survivals of the flaps were observed. At the last follow-up, the effects of flaps in repairing wounds were evaluated according to evaluation standard of efficacy satisfaction; the motion ranges of flexion and extension of the knee joint were measured, and the knee joint function was evaluated according to the Hohl knee joint function evaluation standard; the sensory function in the flap area was evaluated according to the sensory function evaluation standard formulated by the British Medical Research Council; the wound healing and the occurrence of complication affecting motor function of limb of flap donor sites was observed. Data were statistically analyzed with paired sample t test. Results: The perforating branches in flaps originated from descending branches, oblique branches, and rectus femoris branches of lateral circumflex femoral artery in 7, 6, and 4 patients, respectively. The flaps with blood supply from descending branches, oblique branches, and rectus femoris branches of lateral circumflex femoral artery were type 1, 2, and 3 retrograde anterolateral thigh perforator flaps, respectively. The preoperative CTA examination of lateral circumflex femoral artery and its branches were consistent with those observed during operation. The relative lengths of vascular pedicles of type 1, 2, and 3 retrograde anterolateral thigh perforator flaps calculated after CTA examination were 0.32±0.13, 0.56±0.07, and 0.56±0.15, which were close to 0.35±0.12, 0.52±0.10, and 0.53±0.12 measured and calculated during operation, respectively (t=0.45, 0.80, 0.31, P>0.05). All flaps survived in 17 cases without vascular crisis. At the last follow-up, 16 patients were satisfied with effects of flaps in wound repair, with 1 patient feeling average about the effect; the flexion range of knee joint was 100-120°, and the extension range of knee joint was -2-0°; knee joint function was evaluated as excellent in 9 cases, good in 7 cases, and poor in 1 case; the sensory function of the flap area reached S4 level in 2 cases, S3 level in 8 cases, and S2 level in 7 cases; the wounds in flap donor sites healed well; there was no adverse effect in motor function of limbs. Conclusions: Retrograde anterolateral thigh perforator flap is an effective method for repairing skin and soft tissue defects around the knee or in proximal lower leg. Preoperative CTA examination can fully show the anatomical characteristics of the branches of the lateral circumflex femoral artery and the perforating vessels of each branch, which can guide preoperative flap design and operation, thus shortening operation time and improving flap survival rate, with good clinical effects.

Abstract
Objective: To explore the risk factors for mortality in pediatric acute respiratory distress syndrome (PARDS) requiring extracorporeal membrane oxygenation (ECMO) support. Methods: Clinical data of 109 patients with severe PARDS supported by ECMO, who were hospitalized in 6 ECMO centers in China from September 2012 to February 2020, were retrospectively analyzed. They were divided into survival group and death group according to the prognosis. Chi-square test and rank sum test were used to compare the variables between the two groups, including the demographic data, laboratory examination results, clinical data before and after ECMO, and other supportive treatment. Univariate and multivariate Logistic regression models were used to analyze the prognostic risk factors. Results: In these 109 cases, 54 died and 55 survived. Compared with the survival group, the death group had higher incidences of acute kidney injury (AKI) (48.1% (26/54) vs. 21.8% (12/55), χ²=8.318, P=0.004) and coagulation dysfunction (22.2% (12/54) vs. 7.3% (4/55), χ²=4.862, P=0.027), and higher rate of renal replacement therapy (48.1% (26/54) vs. 21.8% (12/55), χ²=9.694, P=0.008) during ECMO support. Logistic regression analysis showed that continuous renal replacement therapy (CRRT) and AKI were independent risk factors for death in patients with severe PARDS requiring ECMO support (HR=3.88,95%CI 1.04-14.52, HR=4.84,95%CI 1.21-19.46, both P<0.05). Conclusion: AKI and CRRT are independent risk factors for predicting mortality in patients with severe PARDS requiring ECMO support.

Abstract
Objective: To investigate the prenatal diagnosis, integrated management and prognosis of fetal complete transposition of the great arteries (D-TGA) detected by ultrasonography. Methods: The prenatal diagnosis, integrated management and prognosis of 19 D-TGA fetuses found by ultrasound during pregnancy in Peking University People's Hospital from January 2014 to June 2019 were analyzed retrospectively. Results: The incidence of D-TGA was 0.12% (19/16 028) among fetuses diagnosed by ultrasound during 5 years. Among the 19 cases, there were 7 cases (7/19) of D-TGA alone, 7 cases (7/19) of D-TGA combined with ventricular septal defect (VSD), 5 cases (5/19) of D-TGA combined with other cardiac malformations; 2 cases (2/19) of D-TGA combined with extra cardiac malformations, and 1 case (1/19) of fetal growth restriction. Nuchal translucency (NT) thickening was found in 3 cases (3/19) at the first trimester of pregnancy. Among the 19 D-TGA fetuses found by ultrasound examination, 18 (18/19) had chromosome karyotype analysis of fetuses or newborns, and chromosomal abnormalities were found in 2 cases, all of which were terminated in the second trimester of pregnancy. The integrated management and multidisciplinary diagnosis and treatment of D-TGA fetuses during pregnancy and perinatal period were carried out. Nine cases (9/19) had induction in the second trimester of pregnancy, 10 cases (10/19) were delivered at term, and the gestational week of delivery was (38.3±0.7) weeks, among which 6 cases (6/10) were delivered by caesarean section due to obstetric factors, and 4 cases (4/10) were delivered by vaginal birth. The oxygen saturation was (69.2±11.3)% at birth and (77.8±6.7)% when transferred to the department of pediatrics. Except for one case lost to follow-up, the other 9 newborns received operation. The average operation time was (21.8±22.1) days after birth, 8 cases (8/9) completed one operation and 1 case (1/9) performed two operations. All of the 9 cases treated by surgery were followed up well. Conclusions: Prenatal diagnosis, individualized evaluation and integrated management during pregnancy and perinatal period should be carried out for the patients with fetal D-TGA detected by ultrasound. Fetal D-TGA is not an indication of cesarean section. The open of ductus arteriosus can be maintained with drugs when necessary after birth, and a good prognosis could be obtained through surgery.

Abstract
Objective: To describe the clinicopathological features of pulmonary artery intimal sarcoma (PAIS), and to understand its molecular alterations. Methods: Sixty cases of pulmonary artery endarterectomy performed at the China-Japan Friendship Hospital, Beijing, China from January 2017 to January 2020 were reviewed. Clinical data of 5 patients with pulmonary artery intimal sarcoma were collected. Hematoxylin-eosin staining, immunohistochemistry staining and fluorescence in situ hybridization (FISH) were performed to evaluate the pathological features. RNA sequencing was conducted to assess the fusion gene changes in PAIS. Results: The detection rate of PAIS was 8.3% (5/60), with the median age of 49 years and a female predominance. Their clinical manifestations were non-specific. Histopathological examination showed that the tumors were composed of malignant spindle or epithelioid cells, with various degrees of atypia. Focal heterologous osteosarcomatous or leiomyosarcomatous differentiation was noted. The tumor cells could express PDGFRA, CDK4 and MDM2 with co-amplification of MDM2, CDK4 and EGFR genes. RNA sequencing detected multiple in-frame fusions in the tumors. Conclusions: PAIS is a rare, highly heterogeneous, and poorly-or un-differentiated sarcoma accompanied by complex changes of multiple genes.It has no known effective treatments, and thus has a poor prognosis.

Abstract
Objective: To explore the correlation between the body mass index (BMI) trajectories and new-onset non-alcoholic fatty liver disease (NAFLD) so as to provide a scientific basis for the prevention and treatment of NAFLD. Methods: A total of 16388 observation subjects that met the inclusion criteria in the Kailuan study were used to form a cohort study. According to the BMI values of the observed subjects during annual physical examinations from 2006 to 2007, 2008 to 2009 and 2010 to 2011, SAS Proc Traj was used to determine four different BMI trajectories groups, namely, the low-stable medium-stable, medium-high and high-stable group. NAFLD incidence in each group was followed up during annual physical examinations from 2012 to 2013, 2014-2015 and 2016-2017. A total of 14998 observation subjects were finally included in the statistical analysis. The cumulative incidences of NAFLD differences in the four groups were compared. The Cox's proportional hazards regression model was used to analyze the correlation between different BMI trajectories and new-onset NAFLD. One-way analysis of variance was used to compare the intergroup difference of measurement data, and pairwise comparisons were conducted. LSD test was used for the homogeneity of variance. Dunnett's T3 test was used for heterogeneity of variances. χ (2) test was used to compare the count data, and the difference of NAFLD cumulative incidence rate between the different BMI trajectories groups was compared by log-rank test. Results: (1) the cumulative incidence of NAFLD was increased with the increase of BMI trajectories, which were 31%, 47%, 63%, 77%, respectively, and the difference was statistically significant (P < 0.01). (2) after adjusting for multiple confounding factors such as age and gender with the Cox's proportional hazards regression model, the risk of NAFLD in the BMI medium stable, medium-high, and high stable group was still 1.757 times [95% confidence interval (CI): 1.589 ~ 1.942], 2.612 (95%CI: 2.353 ~ 2.900), 3.566 (95%CI: 3.129 ~ 4.064) of the low-stable group (P < 0.01). Conclusion: The risk of NAFLD increases with increase of BMI trajectories, and long-term high levels of BMI are independent risk factors for the onset of NAFLD.

Abstract
Objective: To investigate the features of the full-field electroretinogram (FERG) in patients with ocular surface alkaline injury, and to clarify the clinical significance of FERG examination in alkaline ocular trauma. Methods: Retrospective series of case study. A total of 22 patients with chemical ocular surface injury who were treated in the Department of Ophthalmology of Peking University Third Hospital from May 2018 to January 2020 were selected, including 20 males (25 eyes) and 2 females (2 eyes). The age ranged from 19 to 60 years old (average, 41). There were 17 eyes with alkaline ocular trauma, 7 eyes with thermal burn, and 3 eyes with acid ocular trauma. Seventeen contralateral healthy eyes in patients with unilateral mechanical trauma were used as controls. Fourteen alkaline trauma eyes with visual acuity records were further observed according to the degree of visual impairment. All patients were subjected to different flash intensity stimuli in accordance with a standard of the International Society for Clinical Electrophysiology of Vision for dark-adapted and light-adapted full-field FERG. One-way ANOVA and SNK-q was used for the comparison between groups. The unpaired t test was used for the comparison of patients with different vision. Results: Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG b-wave under the dark stimulation of 0.01 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (135±85), (169±55), and (112±43) versus (341±53) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=31.38; q=8.94, 5.70, 5.45;all P<0.01). Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG a-wave under the dark stimulation of 3.00 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (178±78), (172±35), and (99±53) versus (334±60) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=24.33; q=7.04, 5.60, 5.80;all P<0.01). Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG b-wave under the dark stimulation of 3.00 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (354±79), (342±77), and (352±201) versus (600±78) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=27.68; q=8.11, 6.51, 4.48; all P<0.01). Compared with healthy eyes the injured eyes' amplitude of dark adaption FERG OPs under the dark stimulation of 3.00 cd·s·m-2 in alkaline ocular trauma, thermal burn, acid ocular trauma was (97±54), (107±41), and (45±22) versus (206±32) μV, respectively; compared with healthy eyes, the differences were statistically significant (F=25.03; q=7.36, 5.13, 5.96; all P<0.01).There was no significant difference in FERG between patients with visual acuity≥0.2 and those with visual acuity<0.2 (P>0.05) after alkaline ocular trauma. Conclusions: By detecting the amplitude change of FERG wave form of chemical ocular trauma, in this study, the amplitude of FERG wave form in alkaline ocular trauma was generally decreased. It's suggested that alkaline ocular trauma can cause damage to the rod and cone systems of retinal. (Chin J Ophthalmol, 2020, 56: 514-518).

Abstract
Objective: The purpose of this study was to explore the association between gene in the potassium recycling pathway 4 (KCNQ4) polymorphisms and the susceptibility to noise-induced hearing loss (NIHL) , and analysis the effect of cumulative noise exposure (CNE) and noise exposure duration on this association. Methods: A nested case-control study with 1∶1 matched was used based on the cohort of noise exposure in a steel factory. A total of 286 cases were selected as the group of hearing loss and 286 controls were chosen according to the matching standards of same gender, same type of work, age difference ≤ 5 years, noise exposure duration ≤ 2 years. The single nucleotide polymorphisms (SNPs) of rs4660468, rs4660470, rs34287852 in KCNQ4 were genotyped by SNPscan(TM) method. The codominant, dominant and recessive models were established to study KCNQ4 polymorphisms and the susceptibility to NIHL by single-factor conditional logistic regression analysis. The COX regression analysis was used to analyze the risk of developing NIHL in individuals with different genotypes along with the extending of noise exposure duration or CNE. Results: In the case of CNE≤96 dB (A) ·year, the risk of developing NIHL in individuals with TA genotype of rs4660470 was 2.197 times than individuals with TT genotypes (95%CI: 1.032~4.677) , and those with TA+AA and TT genotypes (HR=2.467, 95%CI: 1.025~5.934) With the increase of noise exposure duration, in rs4660470, individuals with TA genotype had a higher risk of suffering NIHL than those with TT genotype (HR=1.461, 95%CI: 1.061~2.011) , individuals with TA and/or AA genotype had a earlier risk of suffering NIHL than those with TT genotype. Conclusion: The mutant allele A of rs4660470 in KCNQ4 may be a risk factor for developing NIHL, CNE≤100 dB (A) ·year or the increase of noise exposure duration may further increase the risk of NIHL.

Abstract
Objective: To investigate the association between the single nucleotide polymorphisms (SNPS) at rs1695 and rs6591256 in glutathione S-transferase P1 (GSTP1) gene and susceptibility to noise-induced hearing loss in Chinese Han workers exposed to noise. Methods: Using the 1: 1 nested case-control study and taking 6297 workers exposed to noise in a steel plant in Henan province as the cohort study population in July 2019, we screened those who have been exposed to noise for ≥3 years and whose binaural high frequency (3000, 4000, 6000 Hz) average hearing threshold is ≥40 dB (A) into the case group. The control group was selected according to the matching criteria of the same sex, same type of work, and the age difference was not more than 5 years old, and the working age difference was not more than 2 years. 276 subjects were selected into the case group and the control group respectively. The medium and high throughout single nucleotide polymorphism typing technology (SNPscanTM technology) was used to detect the polymorphism of three nucleotide sites of GSR gene, and conditional logistic regression was used to analyze the relationship between single nucleotide polymorphism (SNP) and NIHL, and the relationship between different polymorphic sites and the risk of NIHL after adjusting covariates. After stratification with different cumulative noise exposure (CNE) , Conditional logistic regression analysis was used to analysis the risk of NIHL at different loci. Results: The mean and standard deviation of age of the selected subjects was (40.28±8.00) , the mean and standard deviation of noise-exposed working years was (18.7±8.92) years. The range of noise exposure levels and comulative noise exposure were 80.05-93.35dB (A) and 86.83-107.92 dB (A) ·year, respectively. Compared with the control group, there were no statistically significant differences in age, noise-exposured working years, intensity of noise exposure, CNE, gender, drinking, hypertension prevalence and noise exposure level in the hearing loss group (P>0.05) , while there were statistically difference in smoking, binaural high-frequency average hearing threshold and binaural speech frequency (P<0.05) . After adjusting for smoking, drinking, hypertension and other factors, in the co-dominant model, compared with GGgenotype, the risk of NIHL was higher in rs1002149 GT genotype and rs2251780 GA genotype (OR=1.558, 95%CI: 1.028-2.361; OR=1.550, 95%CI: 1.020-2.355, P<0.05) ; compared with TT/GT genotype, the rs1002149 TT genotype has a higher risk of developing NIHL (OR=1.494, 95%CI: 1.002-2.228, P<0.05) , while rs3779647 genotype had no relationship with the risk of NIHL (P>0.05) . In the equivalent sound level (L(Aeq)) of noise >85 dB (A) stratification, compared with GG genotype, carrying rs1002149 GT genotype and rs2251780 GT genotype has higher risk of nihl (OR=1.801, 95%CI: 1.093-2.967; OR=1.720, 95%CI: 1.050-2.817, P<0.05) . Haplotype analysis of two sites, rs1002149 and rs2251780, was not found to be related to NIIHL susceptibility. Conclusion: The allele G of rs1695 and rs6591256 may be risk factors of NIHL.

Abstract
Objective: To explore the relationship among CDH23 gene variation and the risk of noise-induced hearing loss (NIHL) . Methods: The nested case-control study was performed and this study followed a cohort of 6297 noise-exposed workers in a steel factory of Henan province in China from January 1, 2006 to December 31, 2015. In July 2019, subjects whose average hearing threshold were more than 40 dB in high frequency were defined as the case group, and subjects whose average hearing threshold were less than 35 dB in high frequency and less than 25 dB in speech frequency were defined as the control group. A nested case-control study which included 572 subjects was carried out, in which subjects consisted of 286 cases and 286 controls. 18 single nucleotide polymorphisms (SNPs) in CDH23 were selected and genotyped, then we analyzed the association among SNPs in CDH23, haplotypes in CDH23 and NIHL risk. Logistic regression was performed to analyze the main effects of SNPs and the interactions between CNE and SNPs adjusting cumulative noise exposure (CNE) , smoking, drinking, physical exercise and hypertension. Moreover, the association between haplotypes in CDH23 and NIHL risk were also analyzed. We ananlyzed the relationship amongst different SNP groups and NIHL risk using the generalized multifactor dimensionality reduction (GMDR) method. Results: The results suggested that significant associations were observed for rs3802711, rs3752751, rs3752752, rs11592462, rs10762480, rs3747867 for NIHL overall and/or various CNE strata by adjusting CNE, smoking, drinking, physical exercise and blood pressure. For rs3802711, workers exposure to noise carrying the AA/GA genotype of rs3802711 increased risk of NIHL than those carrying GG genotype (OR=3.121; 95%CI:1.054-9.239, P=0.035) in overall; In the stratified analysis of CNE (>97 dB (A) ·year at rs3802711 locus, workers exposure to noise carrying GA genotype (OR=2.056; 95%CI:1.226~3.448, P=0.006) and GA+AA/GA genotype (OR=2.221; 95%CI:1.340~3.681, P=0.002) increased NIHL risk. For rs11592462, workers exposure to noise carrying the GG genotype of rs11592462 increased risk of NIHL than those carrying CC genotype in overall (OR=3.951; 95%CI:1.104-14.137, P=0.04) ; workers exposure to noise carrying the GG genotype of rs11592462 increased risk of NIHL than those carrying CG+CC genotype in overall (OR=4.06; 95%CI:1.145-14.391, P=0.03) . After adjusting CNE, smoking, drinking, physical exercise and blood pressure, the haplotypes of CDH23 rs1227049, rs10999947, rs3752752, rs3752751, rs10762480, rs3802711, rs11592462, rs10466026, rs4747194, rs4747195 were not associated with the risk of NIHL. GMDR analysis showed no association between SNP combination and NIHL risk after adjusting CNE, smoking, drinking, physical exercise and blood pressure. Conclusion: Gene polymorphisms in CDH23 might associate significantly with the risk of NIHL.

Abstract
Objective: To identify association between genetic polymorphism in the Glutathione peroxidase 1 gene (GPX1) and noise-induced hearing loss (NIHL) . Methods: A nested case control study was conducted based on a cohort of noise-exposed subjects. 392 cases were selected from the steel factory in Henan Province, 392 matched control subjects for each case were designated on the basis of the matched criterion including same gender, age (±5years) and duration of exposure to noise (±2years) . Two single nucleotide polymorphisms (SNPs) of GPX1 were genotyped by SNPscanTM multiplex SNP genotyping kit. Hardy-Weinberg equilibrium (HWE) tests were performed using Pearson's χ(2) for each SNP among control group, effects of genotypes of GPX1 on NIHL were analyzed by logistic regression. Results: All two SNPs were in HWE. After adjustment for covariates including smoking status, rs1987628 polymorphism was statistically significantly associated with the NIHL risk under codominant and Dominant inheritance models; In the subjects carrying rs1987628 GA genotype had a higher NIHL risk than those carrying the GG genotype, the adjusted OR value was 1.803 (95%CI 1.215-2.676, P=0.003) . And meanwhile, rs1987628 GA+AA genotype had a higher NIHL risk than those carrying the GG genotype, the adjusted OR value was 1.762 (95%CI 1.197-2.593, P=0.004) . Conclusion: It was suggested that genetic polymorphism in the GPX1 gene might be the genetic susceptible factor for NIHL.

Abstract
Objective: To investigate the association between the single nucleotide polymorphisms (SNPS) at rs1695 and rs6591256 in glutathione S-transferase P1 (GSTP1) gene and susceptibility to noise-induced hearing loss in Chinese Han workers exposed to noise. Methods: A 1: 2 matched nested case-control study was performed, which based on the cohort of 6297 workers exposed to noise in an iron and steel plant in Henan, China, who were followed up from January 1, 2006 to December 31, 2015. According to the criteria of binaural average high-frequency hearing threshold ≥40 dB, a total of 292 workers were enrolled as hearing loss group; after the adjustment for sex, type of work, age (difference≤5 years) , and working years of noise exposure (difference≤2 years) , according to the criteria of binaural average high-frequency hearing threshold <35 dB, and the speech frequency hearing threshold of any ear at any frequency band ≤25 dB, a total of 584 workers were enrolled as control group. The single nucleotide polymorphisms (SNPs) of rs1695 and rs6591256 in GSTP1 were genotyped by high throughput SNP genotyping assay. Hardy-Weinberg equilibrium of control group was checked. The association between the SNPs at the two loci and susceptibility to NIHL was analyzed. Results: The L(Aeq, 8 h) range of workers exposed to noise was 80.2-98.8 dB (A) . The risk of NIHL in individuals with allele G of rs1695 was 1.291 times of those with allele A (95%CI: 1.042-1.598, P<0.05) . The risk of NIHL in individuals with allele G of rs6591256 was 1.390 times of those with allele A (95%CI: 1.119-1.728, P<0.05) . The risk of NIHL in individuals with AG and GG genotypes of rs6591256 was 1.437 times of those with AA genotype (95%CI: 1.057-1.952, P<0.05) . With the increase of noise exposure duration, individuals with AG and GG genotypes of rs6591256 had a higher risk of NIHL than those with AA genotype (HR=1.273, 95%CI: 1.002-1.616, P<0.05) . Conclusion: The allele G of rs1695 and rs6591256 may be risk factors of NIHL.

Abstract
Objective: To investigate the strong expression (S+) of P53 and BCL2 proteins in MYC/BCL2 double-expression DLBCL (DEL) and whether they can be used for the prognostic evaluation and stratified diagnosis of DELs. Methods: Tissue microarray were made by filed FFPE blocks of 174 DLBCL cases. The translocation of MYC, BCL2 and BCL6 genes were detected by FISH, and the proteins were detected by IHC. Data of clinicopathologic features and follow up of patients were collected and OS (overall survival) and PFS (progression free survival) were analyzed by statistics. Results: Eight double-hit lymphomas (DHLs) were identified in all cases, and 45 DELs were selected from 166 remaining cases, which have no significant difference in OS and PFS compared with non-DEL cases (P=0.668 and P=0.790) . Of 42 DEL-cases with follow up data, 24 cases with P53+ or/and BCL2 (S+) are significantly shorter OS and PFS than others (P=0.003 and P=0.000) , in which the cases with P53+/BCL2 (S+) co-expression were the worst prognosis, and P53/BCL2 co-weaker positive DEL cases even have superior OS and PFS than those non-DELs. Although statistics showed that the cases of P53+ or/and BCL2 (S+) have a lower OS and PFS in total cases (P=0.063 and P=0.024) , it is not the case when the DEL-cases take out from total cases, that is the cases with P53+ or/and BCL2 (S+) are as similar OS and PFS as others in non-DEL group (P=0.590 and P=0.550) . Conclusion: The strong expression of P53 and BCL2 proteins can be used as indicators of stratified diagnosis and poor prognosis of DEL.

Abstract
Fully-hydrogenated germanene, named germanane, represents a new nanostructured material for a variety of potential applications, such as electronics and optoelectronics. However, a critical requirement for developing practical and reliable electronic devices based on germanane consists of achieving a flexibly controllable charge carrier and doping level. Different to the conventional doping methods such as ion implantation and diffusion, by first-principles calculations we demonstrate that tetracyanobenzene (TCNB) molecular adsorption could introduce effective p-type doping in germanane due to the combination of germanane with electroactive acceptor molecule TCNB. The corresponding energy difference between the empty band minimum of the dopant and the valence band maximum for electron excitation is 0.173 eV. More importantly, this nondestructive p-type doping could be linearly tuned under an external E-field. Analysis of charge transfer by means of the equivalent capacitor model and the shift of energy levels in the superstructure of germanane/TCNB further reveals that the superposition of the external E-field and molecular adsorption-induced internal E-field plays a key role in the charge transfer between TCNB and germanane, especially in achieving a controllable p-type molecular doping level in germanane. Such convenient and flexible E-field-engineering of p-type molecular doping in germanane would be very helpful for potential applications of germanane-based electronic and optoelectronic devices in the future.

Abstract
Objective: To investigate the ratio of transfer cesarean section after trial of labor and maternal-fetal outcomes based on Robson classifications. Methods: The delivery data by cesarean section in Third Affiliated Hospital of Guangzhou Medical University from January 1st, 2009 to December 31st, 2015 (gestational age ≥28 weeks and newborn birth weight >1 000 g) were retrospectively collected. The ratio of transfer cesarean section after trial of labor and maternal-fetal adverse outcomes were analyzed by weighted adverse outcome score in different Robson classifications. Results: (1) The highest ratio of transfer cesarean section after trial of labor was classification 9 (all abnormal lies, including previous cesarean section and breech were excluded) reached 47.31% (431/911) , followed by classification 2 (nulliparous women with a single cephalic pregnancy, ≥37 weeks gestation who had labour induced) accounted for 44.90%(409/911). (2)The tops of weighted adverse outcome score of transfer cesarean section after trial of labor were classification 10 (single cephalic pregnancy at <37 weeks gestation, including women with previous cesarean delivery) 24.55, classification 5 (single cephalic pregnancy multiparous women, with at least one previous cesarean delivery, ≥37weeks gestation) 3.64. Conclusion: Carefully evaluating the delivery mode and emphasizing the intrapartum management in nulliparous women with a single cephalic pregnancy, at ≥37 weeks gestation who had labour induced and trial of labor after cesarean section is essential to reduce the risk of adverse outcomes in transfer cesarean section after trial of labor.
