Abstract
BACKGROUND Generally, cardiopulmonary resuscitation (CPR) skills decline substantially over time. By combining web-based self-regulated learning with hands-on practice, blended training can be a time- and resource-efficient approach enabling individuals to acquire or refresh CPR skills at their convenience. However, few studies have evaluated the effectiveness of blended CPR refresher training compared with that of the traditional method. OBJECTIVE This study investigated and compared the effectiveness of traditional and blended CPR training through 6-month and 12-month refresher sessions with CPR ability indicators. METHODS This study recruited participants aged ≥18 years from the Automated External Defibrillator Donation Project. The participants were divided into 4 groups based on the format of the CPR training and refresher training received: (1) initial traditional training (a 30-minute instructor-led, hands-on session) and 6-month traditional refresher training (Traditional6 group), (2) initial traditional training and 6-month blended refresher training (an 18-minute e-learning module; Mixed6 group), (3) initial traditional training and 12-month blended refresher training (Mixed12 group), and (4) initial blended training and 6-month blended refresher training (Blended6 group). CPR knowledge and performance were evaluated immediately after initial training. For each group, following initial training but before refresher training, a learning effectiveness assessment was conducted at 12 and 24 months. CPR knowledge was assessed using a written test with 15 multiple-choice questions, and CPR performance was assessed through an examiner-rated skill test and objectively through manikin feedback. A generalized estimating equation model was used to analyze changes in CPR ability indicators. RESULTS This study recruited 1163 participants (mean age 41.82, SD 11.6 years; n=725, 62.3% female), with 332 (28.5%), 270 (23.2%), 258 (22.2%), and 303 (26.1%) participants in the Mixed6, Traditional6, Mixed12, and Blended6 groups, respectively. No significant between-group difference was observed in knowledge acquisition after initial training (P=.23). All groups met the criteria for high-quality CPR skills (ie, average compression depth: 5-6 cm; average compression rate: 100-120 beats/min; chest recoil rate: >80%); however, a higher proportion (98/303, 32.3%) of participants receiving blended training initially demonstrated high-quality CPR skills. At 12 and 24 months, CPR skills had declined in all the groups, but the decline was significantly higher in the Mixed12 group, whereas the differences were not significant between the other groups. This finding indicates that frequent retraining can maintain high-quality CPR skills and that blended refresher training is as effective as traditional refresher training. CONCLUSIONS Our findings indicate that 6-month refresher training sessions for CPR are more effective for maintaining high-quality CPR skills, and that as refreshers, self-learning e-modules are as effective as instructor-led sessions. Although the blended learning approach is cost and resource effective, factors such as participant demographics, training environment, and level of engagement must be considered to maximize the potential of this approach.

Abstract
Objective: To explore the differences in the performance and tissue repair promotion effects of small intestinal submucosa membrane (SIS membrane) and Bio-Gide resorbable collagen membrane (Bio-Gide membrane) by performing the subcutaneous implantation models in mice. Methods: For in vivo studies, we stablished membrane implantation models using 6-8 week-old male C57BL/6 mice. The degradation rates were explored through HE staining analysis at different time points (1, 3, 5, 7, 14 and 28 d, 3 mice/group/time point). The influences of the two membranes on local macrophages and neovasculum were evaluated by immunofluorescence detection of F4/80 and CD31, and the mobilization effects of the two membranes on local stem cells were evaluated by immunohistochemical detection of Ki67 and CD146. For in vitro studies, mice periodontal ligament stem cells (mPDLSCs) were co-cultured with these two membrane materials, and the cell morphologies were observed by scanning electron microscopy. In addition, the gene expressions of Ki67, Cxcl1, Ccl1, Tnfa were investigated by real-time fluorescence quantitative PCR (RT-qPCR). Results: The results of in vivo studies showed that by day 28, there was no significant difference in degradation rate between these two membrane materials [SIS degradation rate: (16.84±4.00) %, Bio-Gide degradation rate: (24.07±3.97) %, P=0.090], illustrating that both of them could maintain the barrier effects for more than one month. In addition, there was no significant difference in the infiltration number of local F4/80 positive macrophages between these two groups by the day 3 after implantation [SIS: (20.67±5.69) cells/visual field, Bio-Gide: (25.33±2.52) cells/visual field, P=0.292]. However, compared with the Bio-Gide membrane, SIS membrane significantly promoted local CD31+vascular regeneration [SIS: (4.67±1.15) cells/visual field, Bio-Gide: (1.00±1.00) cells/visual field, P=0.015] and CD146+stem cell recruitment [SIS: (22.33±4.16) cells/visual field, Bio-Gide: (11.33±2.52) cells/visual field, P=0.025]. The RT-qPCR results also showed that SIS membrane promoted the gene expression of Cxcl1 (SIS vs Bio-Gide P<0.001) in mPDLSCs, but had no effect on the gene expression of Tnfa (SIS vs Bio-Gide P=0.885). Conclusions: SIS membrane showed a similar degradation rate compared with Bio-Gide membrane, and there was no significant difference in the effects of these two membranes on local inflammation or macrophages. Therefore, both of these membranes could meet the barrier effects required by guided tissue regeneration.

Abstract
There is little empirical data on the heightened risk of loneliness among individuals residing in the COVID-19 epicenter or those who have recently left. This study compared the risk of loneliness in individuals residing in Wuhan, the COVID-19 epicenter in China, and those who had recently left during the initial outbreak period to those living in non-epicenter regions. During the COVID-19 outbreak in China in 2020, three samples were obtained using snowball sampling. The samples included 2882 epicenter residents, 1028 left residents, and 2963 non-epicenter residents. Loneliness was assessed using the six-item De Jong Gierveld Loneliness Scale, with a score of two or more indicating the presence of loneliness. 53.5% and 55.2% of epicenter and recently left residents, respectively, experienced loneliness, which was significantly higher than the 43.9% observed in non-epicenter residents. After adjusting for covariates, the risk of loneliness remained statistically significant for both epicenter and left residents (OR = 1.35, P < 0.001 and OR = 1.20, P = 0.017, respectively), when compared to non-epicenter residents. Individuals residing in the COVID-19 epicenter, as well as those who have recently left, are at a heightened risk of loneliness during the outbreak. These individuals need psychosocial support to mitigate their risk of loneliness and promote their psychological wellbeing.

Abstract
Objectives: To investigate the clinical and genetic features of young Chinese patients with myeloproliferative neoplasms (MPN). Methods: In this cross-sectional study, anonymous questionnaires were distributed to patients with MPN patients nationwide. The respondents were divided into 3 groups based on their age at diagnosis: young (≤40 years) , middle-aged (41-60 years) , and elderly (>60 years) . We compared the clinical and genetic characteristics of three groups of MPN patients. Results: 1727 assessable questionnaires were collected. There were 453 (26.2%) young respondents with MPNs, including 274 with essential thrombocythemia (ET) , 80 with polycythemia vera (PV) , and 99 with myelofibrosis. Among the young group, 178 (39.3%) were male, and the median age was 31 (18-40) years. In comparison to middle-aged and elderly respondents, young respondents with MPN were more likely to present with a higher proportion of unmarried status (all P<0.001) , a higher education level (all P<0.001) , less comorbidity (ies) , fewer medications (all P<0.001) , and low-risk stratification (all P<0.001) . Younger respondents experienced headache (ET, P<0.001; PV, P=0.007; MF, P=0.001) at diagnosis, had splenomegaly at diagnosis (PV, P<0.001) , and survey (ET, P=0.052; PV, P=0.063) . Younger respondents had fewer thrombotic events at diagnosis (ET, P<0.001; PV, P=0.011) and during the survey (ET, P<0.001; PV, P=0.003) . JAK2 mutations were found in fewer young people (ET, P<0.001; PV, P<0.001; MF, P=0.013) ; however, CALR mutations were found in more young people (ET, P<0.001; MF, P=0.015) . Furthermore, mutations in non-driver genes (ET, P=0.042; PV, P=0.043; MF, P=0.004) and high-molecular risk mutations (ET, P=0.024; PV, P=0.023; MF, P=0.001) were found in fewer young respondents. Conclusion: Compared with middle-aged and elderly patients, young patients with MPN had unique clinical and genetic characteristics.

Abstract
Objective: To investigate the pathogen distribution and antimicrobial resistance among lower respiratory tract infections in patients with hematological malignancies. Methods: Sputum samples were collected from 967 patients with hematological malignancies and lower respiratory tract infections in Department of Hematology,the Second Hospital of Shanxi Medical University from January 2017 to July 2020. The pathogens and drug sensitivity reports were carried out by automatic bacterial identification instruments. WHONET 5.6 and SPSS 20.0 softwares were used for statistical analysis. Results: A total of 961 strains of pathogens were isolated, 516 (53.7%) pathogens were Gram-negative bacteria, mainly 118 strains of Klebsiella pneumonia (12.3%), 68 strains of Pseudomonas aeruginosa (7.1%), 67 strains of Acinetobacter baumannii (7.0%),52 strains of Stenotrophomonas maltophilia (5.4%), 43 strains of Escherichia coli (4.5%), and 42 strains of Enterbacter cloacae (4.4%). There were 171 (17.8%) strains of Gram-positive bacteria and 274 (28.5%) fungi. The drug resistance rates of Pseudomonas aeruginosa and Acinetobacter baumannii to carbapenem were 22.1%-31.3%. Stenotrophomonas maltophilia was sensitive to levofloxacin, compound sulfamethoxazole and minocycline. The antimicrobial resistance rates of these three enterobacteria to carbapenems, cefoperazone/sulbactam, piperacillin/tazobactam were low (<10%). The resistant Gram-positive bacteria to ticoplanin, vancomycin and linazolamide were not detected. Conclusion: The major pathogens related to lower respiratory tract infections in patients with hematological malignancies are gram-negative bacteria in our centre. Different pathogens appear different characteristics of antimicrobial resistance.

Abstract
BACKGROUND Non-invasive fibrosis scores are not yet validated in the newly defined metabolic associated fatty liver disease (MAFLD).
AIM To evaluate the diagnostic performance of four non-invasive scores including aspartate aminotransferase to platelet ratio index (APRI), fibrosis-4 index (FIB-4), body mass index, aspartate aminotransferase/alanine aminotransferase ratio, diabetes score (BARD), and nonalcoholic fatty liver disease fibrosis score (NFS) in patients with MAFLD.
METHODS Consecutive patients with histologically confirmed MAFLD were included. The discrimination ability of different non-invasive scores was compared.
RESULTS A total of 417 patients were included; 156 (37.4%) of them had advanced fibrosis (Metavir ≥ F3). The area under receiver operating characteristic curve of FIB-4, NFS, APRI, and BARD for predicting advanced fibrosis was 0.736, 0.724, 0.671, and 0.609, respectively. The area under receiver operating characteristic curve of FIB-4 and NFS was similar (P = 0.523), while the difference between FIB-4 and APRI (P = 0.001) and FIB-4 and BARD (P < 0.001) was statistically significant. The best thresholds of FIB-4, NFS, APRI, and BARD for diagnosis of advanced fibrosis in MAFLD were 1.05, -2.1, 0.42, and 2. A subgroup analysis showed that FIB-4, APRI, and NFS performed worse in the pure MAFLD group than in the hepatitis B virus-MAFLD group.
CONCLUSION APRI and BARD scores do not perform well in MAFLD. The FIB-4 and NFS could be more useful, but a new threshold is needed. Novel non-invasive scoring systems for fibrosis are required for MAFLD.

Abstract
BACKGROUND & PROBLEMS In case of fire in the hemodialysis room, it is necessary to help patients get away from dialysis machines smoothly and safely and evacuate the room rapidly. Our unit is located on a higher floor. An investigation showed that the accuracy rate for fire response awareness among the staffs in our unit was only 57.9%, while the accuracy rate of fire response skill operations was only 57.4%. Moreover, 62.0% of the staffs were not clear about the task grouping and task content of fire response. Confusion in our unit regarding the definition of patient mobility led to staffs classifying patients based on subjective perceptions and standards. Moreover, the unit also lacked an audit system for fire emergency operations and fire-response-related learning materials. PURPOSE To improve staff knowledge and skills related to fire emergency response in the hemodialysis room to 100%. RESOLUTION The project team worked out solutions such as adding a self-defense fire-fighting group to the dialysis information system, producing fire emergency response learning materials, establishing a seed personnel system, organizing on-the-job education, organizing fire response simulation drills, and implementing an audit system. RESULTS The awareness of fire emergency response and the accuracy of skill operation among the staff were both improved to 100%, and there were statistically significant differences between the pre-test and post-test paired t-test results. Furthermore, consistent implementation of these resolution measures maintained the staff`s fire emergency response skills at 100% between June 2019 and May 2020. CONCLUSIONS Tabletop simulation, practice drills, and skill operation audits are effective tools for improving the ability of staff in the hemodialysis room to respond to fire emergencies. It is recommended that institutions produce tabletop simulation props and combine regular on-site drills to improve the readiness of their staffs to respond to fire emergencies, which will shorten the response time during incidents.

Abstract
BACKGROUND Metabolic associated fatty liver disease (MAFLD) is a novel concept proposed in 2020.
AIM To compare the characteristics of MAFLD and MAFLD with hepatitis B virus (HBV) infection.
METHODS Patients with histopathologically proven MAFLD from a single medical center were included. Patients were divided into MAFLD group (without HBV infection) and HBV-MAFLD group (with HBV infection). Propensity score matching was utilized to balance the baseline characteristics between two groups.
RESULTS A total of 417 cases with MAFLD were included, 359 (86.1%) of whom were infected with HBV. There were significantly more males in the HBV-MAFLD group than in the MAFLD group (P < 0.05). After propensity score matching, 58 pairs were successfully matched with no significant differences found in gender, age, body mass index, lipid levels, liver enzymes, and the other metabolic associated comorbidities between the two groups (P > 0.05). The rank sum test results showed that the degree of liver steatosis in the MAFLD group was more severe than that in the HBV-MAFLD group, while the degree of inflammation and fibrosis in the liver was less severe (P < 0.05). In multivariate analysis, HBV infection was associated with significantly lower grade of hepatic steatosis [odds ratio (OR) = 0.088, 95% confidence interval (CI): 0.027-0.291] but higher inflammation level (OR = 4.059, 95%CI: 1.403-11.742) and fibrosis level (OR = 3.016, 95%CI: 1.087-8.370) after adjusting for age, gender, and other metabolic parameters.
CONCLUSION HBV infection is associated with similar metabolic risks, lower steatosis grade, higher inflammation, and fibrosis grade in MAFLD patients.

Abstract
Objective: To explore the clinical characteristics of acute myeloid leukemia (AML) complicated with simultaneous multiple primary cancer (SMPC). Methods: The data of 12 AML patients with SMPC hospitalized in the Affiliated Cancer Hospital of Zhengzhou University, the First Affiliated Hospital of Nanyang Medical College, the Xinhua District Hospital of Pingdingshan City and the First People's Hospital of Pingdingshan City from March 2014 to July 2019 were analyzed retrospectively, and their clinical features, treatment and prognosis were summarized. Results: Among the 12 patients, there were 6 males and 6 females, with a median age of 58 years (39-70 years). AML classification: according to French-American-British (FAB) classification, the 12 AML patients were classified as M0 1, M1 1, M2a 5, M2b 1, M3 2, M5 2; according to National Comprehensive Cancer Network (NCCN) prognosis stratified, low risk group 1 case, medium risk group 4 cases, high risk group 7 cases; classification of solid tumors: 3 cases of lung cancer, 1 case of breast cancer, 2 cases of gastric cancer, 3 cases of esophageal cancer, 1 case of rectal neuroendocrine tumor, 1 case of invasive hydatidiform mole and 1 case of sigmoid colon cancer. The median time interval for the diagnosis of two primary malignant tumors was 4 (from 2.6 to 5.6) months. Results of gene mutation detection: AML prognostic gene detection results: a total of 12 kinds of gene abnormalities including ASXL1, JAK2, TET2, U2AF1, ABCB1, FLT3-ITD, RUNX1, SETBPIT, TET2 (single nucleotide polymorphism, SNP), p53, IKZF1 and IDH2 were detected, and solid tumor related genes were detected: a total of 4 kinds of gene abnormalities including Her-2, EGFR, K-RAS and MSI were detected. Survival: among the 12 patients, 1 case was lost during follow-up, 2 cases were still in treatment, 3 cases ended treatment and the condition was stable, 6 cases died. The median overall survival of 12 patients was 12.5 (from 3.8 to 48.0) months. Conclusions: It is not clear whether there is a certain correlation between the simultaneous occurrence of AML and solid tumors. Patients with AML and synchronous solid tumors are not unusual. Both tumors should be treated aggressively at the same time.

Abstract
BACKGROUND The diagnosis of bacterial infection is difficult in patients with acute-on-chronic liver failure (ACLF).
AIM To evaluate the diagnostic accuracy of widely used parameters for bacterial infection in ACLF and to develop a simple scoring system to improve diagnostic efficiency.
METHODS This was a retrospective study. Procalcitonin (PCT), white blood cells (WBC), proportion of neutrophils (N%), and C-reactive protein (CRP) were examined. Logistic regression was used to select variables for the scoring models and receiver operating characteristic curve (ROC) analysis was used to evaluate the diagnostic value of different indices.
RESULTS This study included 386 patients with ACLF, 169 (43.78%) of whom had bacterial infection on admission. The area under the ROC (AUROC) of PCT, CRP, WBC and N% for the diagnosis of bacterial infection ranged from 0.637 to 0.692, with no significant difference between them. Logistic regression showed that only N%, PCT, and CRP could independently predict infection. A novel scoring system (infection score) comprised of N%, PCT and CRP was developed. The AUROC of the infection score was 0.740, which was significantly higher than that for the other four indices (infection score vs N%, PCT, CRP, and WBC, P = 0.0056, 0.0001, 0.0483 and 0.0008, respectively). The best cutoff point for the infection score was 4 points, with a sensitivity of 78.05%, a specificity of 55.29%, a positive predictive value of 57.91% and a negative predictive value of 76.16%.
CONCLUSION The infection score is a simple and useful tool for discriminating bacterial infection in ACLF.

Abstract
Ternary chalcogenides, GeSb2Se3 and Ge3Sb4Se7, were synthesized and characterized. These chalcogenides are the first ternary selenides in a ternary Ge-Sb-Se system that feature a layer structure related to black phosphorus and SnSe-type structures. Both compounds contain a ∞1[Sb2Se2]2- unit with Sb+ cations in a zigzag Sb-Sb chain structure, and Sb3+ cations in a distorted NaCl100-type of ∞1[Gen-2Sb2Sen]2+ unit (n = 4, 5). These materials exhibit n-type semiconducting properties with thermal conductivity significantly lower than that of GeSe and Sb2Se3, which could be correlated to the 1D Sb+ chain and disordered sites with different Ge/Sb compositions. It is anticipated that these newly discovered ternary chalcogenides may provide unique properties with enhanced thermoelectric properties.

Abstract
To explore effects of the sDR5-Fc fusion protein on ulcerative colitis of infant mice via the TRAIL-DR5 pathway, 50 female mice were randomly divided into 5 groups, i.e., control group (group A), dextran sulfate sodium group (group B), hIgG group (group C), 10 mg/kg sDR5-Fc group (group D), and 20 mg/ kg sDR5-Fc group (group E). The acute ulcerative colitis models were established. The weights and disease activity index (DAI) of each group were monitored daily. In addition, the pathological changes of colon tissues were observed by Hematoxylin-Eosin staining. The number of macrophages in colon tissues was detected by immunohistochemistry assay. Changes in the expression of inflammatory factors in colon tissues were detected by quantitative real-time polymerase chain reaction (PCR). Lipopolysaccharide (LPS) of different concentrations was utilized alone or in combination with TRAIL to stimulate the NCM460 cells. The activation of NLRP3 inflammasomes was detected by Western blot. The apoptosis of NCM460 cells was detected by flow cytometry. The results showed that in groups B and C, the body weights decreased, the DAI increased, the colon epithelial cells were injured, the inflammatory cells were infiltrated, and the macrophages in colon tissues increased significantly. In groups D and E, the body weights increased, the DAI decreased, the inflammation was significantly improved, the macrophages decreased significantly, and the gene expression levels of NLRP3, Caspase-1, and IL-1β decreased significantly. Thus, sDR5-Fc could inhibit the activation of NLRP3 inflammasomes induced by TRAIL, thereby decreasing the apoptosis of NCM460 cells. In conclusion, the sDR5-Fc fusion protein could block the TRAIL-DR5 pathway to reduce the expression of NLRP3 inflammasomes, thereby improving ulcerative colitis.

Abstract
Objective We investigated the “BURP” maneuver’s effect on the association between
difficult laryngoscopy and difficult intubation, and predictors of a
difficult airway. Methods Adult patients who underwent general anesthesia and tracheal intubation from
September 2016 to May 2018 were included. The “BURP” maneuver was performed
when glottic exposure was classified as Cormack–Lehane grade 3 or 4,
suggesting difficult laryngoscopy. The thyromental distance, modified
Mallampati score, and interincisor distance were assessed before
anesthesia. Results Among this study’s 2028 patients, the “BURP” maneuver decreased difficult
laryngoscopies from 428 (21.1%) to 124 (6.1%) cases and increased the
difficult intubation to difficult laryngoscopy ratio from 53/428 (12.4%) to
52/124 (41.9%). For laryngoscopies classified as difficult without the
“BURP” maneuver, the area under the curve (AUC) of the thyromental distance,
modified Mallampati score, and interincisor distance was 0.60, 0.57, and
0.66, respectively. In difficult laryngoscopies using the “BURP” maneuver,
the AUC of the thyromental distance, modified Mallampati score, and
interincisor distance was 0.71, 0.67, and 0.76, respectively. Conclusions The “BURP” maneuver improves the laryngoscopic view and assists in difficult
laryngoscopies. Compared with difficult laryngoscopies without the “BURP”
maneuver, those with the “BURP” maneuver are more closely associated with
difficult intubations and are more predictable. Trial registration:www.chictr.org.cn identifier: ChiCTR-ROC- 16009050.

Abstract
Backgrounds There is a discrepancy between west and east on the relationship between non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease (CKD). This study aimed to find out the possible reason for this and to clarify the association between NAFLD and CKD by analyzing two population-based datasets from the US and China. Methods Two health examination datasets from China and the US were used. CKD was defined as an estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73m2 or and/or abnormal albuminuria and/or overt proteinuria. Binary logistic regression was used to examine the association between NAFLD and CKD. Results A total of 60,965 participants were analyzed, including 11,844 from the US and 51,229 from China. The prevalence of NAFLD was 27.12% in the Chinese population and 36.08% in the US population (p < 0.001). The proportions of CKD and late stage CKD (stages 3–5) were higher in the US population than the Chinese one. NAFLD was independently associated with an increased risk of CKD in Chinese population, whereas in the US population, the NAFLD was not an independent risk factor of CKD. In subgroup analyses which excluded late stages CKD (stages 3–5), the risks of mild renal function decline became consistent: NAFLD was associated with early stages of CKD but not the late stages of CKD in both populations. Conclusion NAFLD increased the risk of early stages of CKD in both Chinese and the US population. The conflicting results reported by previous studies might result from the different proportion of late stages of CKD.

Abstract
Lactobacillus rhamnosus strain ASCC 1520 with high soy isoflavone transformation ability was used to ferment soymilk and added to the diet of mice. The impact of L. rhamnosus fermentation on soy isoflavone metabolites and intestinal bacterial community, in conjunction with fecal enzyme activity and short-chain fatty acids (SCFA) excretion was evaluated. Antibiotics intervention resulted in a decrease in fecal enzyme activities and SCFA. Although long-term intake of soymilk or L. rhamnosus-fermented soymilk did not affect the fecal β-glucuronidase and β-galactosidase activities, it improved the β-glucosidase activity when antibiotics were concomitantly administered. Soymilk or fermented soymilk administration increased the isoflavone metabolites (O-DMA and equol) excreted in urine. Antibiotics decreased the daidzein excretion and its metabolites but showed little effect on glycitein and genistein excretion. Principal coordinates analysis (PCoA) of the 16s rRNA gene sequencing data found a remarkable shift in gut microbiota after soymilk administration and antibiotics treatment. Matastats test of the relative abundance of bacterial taxa revealed Odoribacter (Bacteroidales family), Lactobacillus (Lactobacillales order), and Alistipes (Rikenellaceae family) were enriched in soymilk while bacterial taxa from Bacteroides and Lactobacillus were enriched in L. rhamnosus-fermented soymilk. Furthermore, there was less decrease in bacterial taxa with fermented soymilk group even when antibiotics were concomitantly administered. Overall, this study revealed that the gut microbiota of a healthy host is enough for the whole isoflavone metabolism under normal conditions. Feeding mice with L. rhamnosus-fermented soymilk improved fecal enzyme activity and kept the balance of the gut mirobiota when antibiotics were used. PRACTICAL APPLICATION: Feeding mice with L. rhamnosus-fermented soymilk improved fecal enzyme activity and kept the balance of the gut mirobiota when antibiotics were used.

Abstract
Objective: To investigate the correlation between interleukin-6 (IL-6) single nucleotide polymorphism (SNP) and the occurrence and prognosis of hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). Methods: Patients with chronic hepatic diseases diagnosed as HBV infection in the Hepatology Center of the First Affiliated Hospital of Fujian Medical University from July 2012 to March 2018 were divided into HBV-ACLF and non-ACLF group. SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) was determined by the improved multi-temperature ligase detection reaction (imLDRTM) technique. Simultaneously, case data were reviewed with the 3-months followed up survival condition of the ACLF group. Normally distributed data were expressed as arithmetic means and SDs, and t-test was adopted. Data with skewed distribution were expressed as medians with interquartile range, and were measured by non-parametric test. Multivariate logistic regression analysis was used to analyze the relative risk of genetic polymorphism and HBV-ACLF as well as the relationship between IL-6 SNPs with the occurrence and prognosis of HBV-ACLF. Results: Four hundred patients were included in the study, with 122 (30.5%) in the HBV-ACLF and 278 (69.5%) in the non-ACLF group. There were significant differences in total bilirubin, albumin, and white blood cell count, percentage of neutrophils, platelet count, alanine aminotransferase, aspartate aminotransferase, prothrombin time and international standardized ratio, creatinine and the model for end-stage liver disease score between the two groups (P < 0.001). The genotype of IL-6 genes (rs1800795, rs1800797, rs2069827, and rs2069830) of all subjects showed no mutation or the mutation rate under 1%. There was no significant difference in the genotype of IL-6 (rs1524107, rs2069837, rs2069840 and rs2069845) between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the SNPs in the above four loci of IL-6 gene was not associated with HBV-ACLF risk, nor had significant correlation with the 3-months prognosis. Conclusion: The SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) is unrelated to the occurrence and short-term prognosis of HBV-ACLF.

Abstract
BACKGROUND & PROBLEMS Obtaining complete electronic dialysis nursing records, a tool that facilitates communication between medical teams, is critical in terms of maintaining the continuity of nursing procedures and nursing quality. An analysis of our unit indicated that nurses lacked sufficient familiarity with electronic dialysis nursing record systems. Moreover, they received insufficient training in operating these systems and lacked the guidelines necessary to maintain these records properly. Furthermore, these systems tend to be poorly designed, and an inspection system for dialysis nursing records is currently unavailable. These factors led to a rate of record completeness of only 58.2%. PURPOSE To raise the rate of completeness for electronic nursing records to above 90%. RESOLUTION An intervention was conducted to accomplish seven tasks. These tasks included: modify the electronic dialysis nursing record system, input preset phrases in order to facilitate record compilation in the system, devise a manual to instruct staff on recordkeeping procedures, organize in-service training on system operations, conduct clinical scenario simulations for nurses to practice operating the system, recruit informatics nurses to teach other nurses about the operations, and implement an inspection system for these electronic records. RESULTS After implementing the intervention, the rate of completeness for electronic nursing records improved to 96% and the average time required for nurses to complete a nursing record decreased from 21 mins 35 s to 8 mins 15 s. CONCLUSIONS The developed intervention significantly improved the completeness of electronic nursing records, reduced the time required for recordkeeping, and ensured adequate nursing quality for dialysis patients.

Abstract
AIM To evaluate the long-term efficacy and safety of autologous stem cell transplantation (SCT) for decompensated liver cirrhosis.
METHODS Consecutive patients with decompensated liver cirrhosis were included and assigned into the SCT group and non-transplantation (non-SCT) group according to whether they received SCT treatment. Patients were followed up for ten years. The long-term survival rate and incidence of hepatocellular carcinoma (HCC) were compared between groups.
RESULTS A total of 159 patients were enrolled, including 27 cases in the SCT group and 132 cases in the non-SCT group. The baseline characteristics were significantly different between the two groups. Propensity score matching (PSM) was used to match SCT and non-SCT patients. After PSM, 92 subjects were enrolled in the final analysis, including 23 cases in the SCT group and 69 cases in the non-SCT group. The overall mortality was 73.9% and 55.1%, and the median survival period was 48 and 64 mo, respectively. However, no significant difference was found in the long-term survival rate between the two groups (P > 0.05). In addition, the incidence of HCC was higher in the SCT group than in the non-SCT group (47.8% vs 21.7%, P < 0.05). After adjusting for other covariates, SCT (OR = 3.065, 95%CI: 1.378-6.814) and age (OR = 1.061, 95%CI: 1.021-1.102) were independently correlated with the development of HCC in this decompensated liver cirrhosis cohort.
CONCLUSION Autologous SCT may fail to improve the long-term efficacy and increase the incidence of HCC for decompensated liver cirrhosis. Close monitoring of HCC is strongly recommended in patients undergoing autologous SCT.

Abstract
Von Meyenburg complexes (VMCs) are a rare type of ductal plate malformation. We herein report two Chinese families with VMCs, and the suspicious gene mutation of this disease. Proband A was a 62-year-old woman with abnormal echographic presentation of the liver. She received magnetic resonance imaging (MRI) examination and liver biopsy, and the results showed she had VMCs. Histologically proved hepatocellular carcinoma was found 1 year after the diagnosis of VMCs. Proband B was a 57-year-old woman with intrahepatic diffuse lesions displayed by abdominal ultrasonography. Her final diagnoses were VMCs, congenital hepatic fibrosis, and hepatitis B surface e antigen-negative chronic hepatitis B after a series of examinations. Then, all the family members of both proband A and proband B were screened for VMCs by MRI or ultrasonography. The results showed that four of the 11 family members from two families, including two males and two females, were diagnosed with VMCs. DNA samples were extracted from the peripheral blood of those 11 individuals of two VMCs pedigrees and subjected to polymerase chain reaction amplification of the polycystic kidney and hepatic disease 1 (PKHD1) gene. Two different mutation loci were identified. Heterozygous mutations located in exon 32 (c.4280delG, p.Gly1427ValfsX6) in family A and exon 28 (c.3118C>T, p.Arg1040Ter) in family B were detected. We speculate that PKHD1 gene mutations may be responsible for the development of VMCs.

Abstract
Objective: To evaluate the efficacy and safety of a domestic human plasma derived coagulation Factor Ⅸ concentrate (pd-FⅨ) in patients with hemophilia B. Methods: The study was a multicenter, open-label and single-arm study. The efficacy of pd-F Ⅸ was evaluated by objective performance criteria. The doses of pd-FⅨ were calculated according to the bleeding symptom and disease severity. The infusion efficiency of pd-FⅨ and improvement of bleeding symptoms were measured at 30 minutes and (24±4) h after the first infusion, respectively. Adverse events were recorded. Viral infection and FⅨ inhibitor were detected 90 d after the first infusion. Results: All 36 subjects with hemophilia B were enrolled in the study. The median age of these patients was 31 years old and the median injection doses were 4 (1-17) times. The hemostatic effect of 27/36 (75.00%) and 9/36 (25.00%) acute bleeding events were rated as "excellent" and "better" , respectively. The recovery rate was 111.92% (65.55%-194.28%) at 30 minutes after infusion of FⅨ. There was no adverse event related to FⅨ. No reactivation of HBV, HCV or HIV and FⅨ inhibitor was detected at 90-104 d after the first FⅨ infusion. Conclusion: This domestically made human plasma derived FⅨ concentrate is safe and effective in the treatment of acute bleeding in patients with hemophilia B. Clinical trial registration: China food and Durg Administration, 2016L08027.

Abstract
OBJECTIVE It has been well documented that variant alleles of both ADH1B*2 of alcohol dehydrogenase (ADH) and ALDH2*2 of aldehyde dehydrogenase (ALDH) protect against the development of alcoholism in East Asians. However, it remains unclear whether ADH1B*2 contributes significantly toward the accumulation of systemic blood acetaldehyde and whether it plays a critical role in the alcohol flushing reaction. PARTICIPANTS AND METHODS Sixty-one adult Han Chinese men were recruited and divided into six combinatorial genotypic groups: ALDH2*1/*1-ADH1B*1/*1 (12), ALDH2*1/*1-ADH1B*1/*2 (11), ALDH2*1/*1-ADH1B*2/*2 (11); ALDH2*1/*2-ADH1B*1/*1 (9), ALDH2*1/*2-ADH1B*1/*2 (9), and ALDH2*1/*2-ADH1B*2/*2 (9). After ingesting 0.3 g/kg of alcohol, blood ethanol, acetaldehyde, and acetate concentrations, as well as the facial skin blood flow (FSBF) and pulse rate were measured for 130 min. RESULTS The ALDH2*1/*2 heterozygotes carrying three ADH1B allelotypes showed significantly higher peak levels and areas under the concentration curve (AUCs) of the blood acetaldehyde as well as significantly greater increases in the peak pulse rate and peak FSBF compared with the ALDH2*1/*1 homozygotes. However, no significant differences in peak levels and AUCs of blood ethanol, acetaldehyde or acetate, or the peak cardiovascular responses, were found between the ADH1B allelotypes carrying ALDH2*1/*1 or between those with ALDH2*1/*2. Partial correlation analyses showed that peak blood acetaldehyde, rather than the blood ethanol or acetate, was correlated significantly with the peak responses of pulse rate and FSBF. CONCLUSION Findings indicate that ALDH2*2, rather than ADH1B2*2, is a causal variant allele for the accumulation of blood acetaldehyde and the resultant facial flushing during low alcohol consumption.

Abstract
1. The pharmacokinetics of doxycycline in ducks were investigated after a single intravenous (IV), intramuscular (IM) or oral (PO) dose at 20 mg/kg body weight. 2. The concentrations of doxycycline in plasma samples were assayed using a high performance liquid chromatography method, and pharmacokinetic parameters were calculated using a non-compartmental model. 3. After IV administration, doxycycline had a mean (±SD) distribution volume (Vz) of 1761.9 ± 328.5 ml/kg and was slowly eliminated with a terminal half-life (t₁/₂λz) of 21.21±1.47 h and a total body clearance (Cl) of 57.51 ± 9.50 ml/h/kg. Following PO and IM administration, doxycycline was relatively slowly absorbed - the peak concentrations (Cmax) were 17.57 ± 4.66 μg/ml at 2 h and 25.01 ± 4.18 μg/ml at 1.5 h, respectively. The absolute bioavailabilities (F) of doxycycline after PO and IM administration were 39.13% and 70.71%, respectively. 4. The plasma profile of doxycycline exhibited favourable pharmacokinetics characteristics in Muscovy ducks, such as wide distribution, relatively slow absorption and slow elimination, though oral bioavailability was low.

Abstract
The genes encoding the enzymes for metabolising alcohol dehydrogenase 1B (ADH1B) and aldehyde dehydrogenase 2 (ALDH2) -- exhibit genetic polymorphism and ethnic variations. Although the ALDH2*2 variant allele has been widely accepted as protecting against the development of alcoholism in Asians, the association of the ADH1B*2 variant allele with drinking behaviour remains inconclusive. The goal of this study was to determine whether the polymorphic ADH1B and ALDH2 genes are associated with stroke in male Han Chinese with high alcohol consumption. Sixty-five stroke patients with a history of heavy drinking (HDS) and 83 stroke patients without such a history (NHDS) were recruited for analysis of the ADH1B and ALDH2 genotypes from the stroke registry in the Tri-Service General Hospital, Taipei, Taiwan, between January 2000 and December 2001. The allelotypes of ADH1B and ALDH2 were determined using the polymerase chain reaction-restriction fragment length polymorphism method. The HDS patients (3 per cent) showed a significantly lower ALDH2*2 allele frequency than NHDS patients (27 per cent) (p < 0.001). After controlling for age, patients with HDS were associated with a significantly higher occurrence of cigarette smoking (p < 0.01) and liver dysfunction (p < 0.01). Multiple logistic regression analyses revealed that the ALDH2*2 variant allele was an independent variable exhibiting strong protection (odds ratio 0.072; 95 per cent confidence interval 0.02-0.26) against HDS after adjustment for hypertension, diabetes mellitus, smoking status and liver dysfunction. By contrast, allelic variations in ADH1B exerted no significant effect on HDS. The present study indicated that, unlike ALDH2*2, ADH1B*2 appears not to be a significant negative risk factor for high alcohol consumption in male Han Chinese with stroke.

Abstract
In this paper, we present a miniaturized endoscopic probe, consisted of MEMS micromirror, silicon optical bench (SiOB), grade index (GRIN) lens, single mode optical fiber (SMF) and transparent housing, for optical coherence tomography (OCT) bioimaging. Due to the use of the MEMS micromirror, the endoscopic OCT system is highly suitable for non-invasive imaging diagnosis of a wide variety of inner organs. The probe engineering and proof of concept were demonstrated by obtaining the two-dimensional OCT images with a cover slide and an onion used as standard samples and the axial resolution was around 10µm.

Abstract
AIM To analyze the risk factors of age, sex, course, best corrected visual acuity (BCVA), diopter and fundus features of high myopes with progressive high myopia. METHODS A total of 167 patients with high myopes were categorized into four groups: group 1, age 10-29 years; group 2, age 30-49 years; group 3, age 50-69 years and group 4, age 70-89 years. The refractive errors of all patients were measured without cycloplegia with an autorefractometer. Data of the spherical equivalent (SE) of the refractive errors in diopters (D) and fundus examined by direct ophthalmoscope were used in statistical analysis. RESULTS The number of female was statistically larger than that of male (P<0.01), also the disease course was correlated to the age. The visual acuity of high myopes significantly decreased as they grew older including the higher incidence of lacquer cracker, submacular hemorrhage, Fuchs spots, chorioretinal atrophy. CONCLUSION Female maybe a risk factor of high myopia, advanced age is an important factor of visual acuity decreased. High myopes ought to be treated early to delay the progress of myopia and development of macular degeneration.

Abstract
OBJECTIVES It has been well documented that although homozygosity of the variant aldehyde dehydrogenese-2 (ALDH2) gene allele, ALDH2*2, in Asians almost fully protects against alcoholism, the heterozygosity only affords a partial protection to varying degrees. The partial protection against alcoholism has been ascribed to the faster elimination of acetaldehyde by residual hepatic ALDH2 activity and the lower accumulation in circulation in nonalcoholic heterozygotes. The physiological basis for overcoming the protection in ALDH2*1/*2 alcoholics, however, remains unclear. METHODS To address this question, we recruited a total of 27 Han Chinese alcohol-dependent men, matched by age and body mass index, controlled for normal liver and cardiovascular functions, from a population base of 221 alcoholics. The participants were divided into ALDH2*1/*1 homozygotes (n = 13) and ALDH2*1/*2 heterozygotes (n = 14). After a moderate dose of ethanol (0.5 g/kg body weight), blood ethanol/acetaldehyde/acetate concentrations, cardiac and extracranial/intracranial arterial hemodynamic parameters, as well as self-rated subjective sensations, were measured for 130 min. RESULTS ALDH2*1/*2 alcoholics exhibited significantly higher blood acetaldehyde levels as well as prominent cardiovascular effects and the subjective perceptions, compared with the ALDH2*1/*1 alcoholics. Comparable profiles of blood acetaldehyde were found between heterozygotic alcoholics and the previously reported nonalcoholic heterozygotes intaking the same dose of ethanol. ALDH2*1/*2 alcoholics revealed, however, significantly lower intensities in both physiologic and psychologic responses than did the nonalcoholic heterozygotes. CONCLUSION These results indicate that acetaldehyde, rather than ethanol or acetate, is primarily responsible for the observed alcohol sensitivity reactions in heterozygotic alcoholics and suggest that physiological tolerance and/or innate low sensitivity may play a crucial role in overcoming the deterring response. A potential pharmacogenetic classification of acetaldehydism and alcoholism for alcoholics carrying the different ALDH2 genotypes is proposed.

Abstract
Quaternary selenides of Pb(4)In(x)M(6-x)Se(13) (M = Bi, x = 2.1-2.8; Sb, x = 2) were synthesized by solid-state methods, and their structures were determined from X-ray diffraction of single crystals. These compounds are isostructural with Pb(4)In(2)Bi(4)S(13) and crystallize in orthorhombic space group Pbam (No. 55) with Z = 4; the structure features a three-dimensional framework consisting of Z-shaped ribbon units and corner-sharing infinite one-dimensional [InSe(4)](infinity) chains running parallel to the c-axis, which are connected by Pb atoms to form a three-dimensional structure. Calculations of the band structure and measurements of Seebeck coefficient, electrical conductivity, and diffuse reflectance spectra confirm that these compounds are semiconductors with a narrow band gap. All compounds show semiconducting properties; the Seebeck coefficient of Pb(4)In(2.5)Bi(3.5)Se(13) is -180 microV/K at 295 K.
