Abstract
A 62-year-old female patient presented with no improvement in vision 10 days after undergoing cataract extraction in the right eye. The unaided visual acuity in the right eye was 0.1, and examination with a slit lamp revealed the presence of the intraocular lens with an increased gap between the intraocular lens and the posterior capsule. Anterior segment optical coherence tomography showed a distance of 3.236 mm between the posterior capsule and the posterior surface of the intraocular lens. Based on the medical history, ocular examination, and auxiliary examinations, a diagnosis of right eye capsular blockage syndrome was made. Nd:YAG laser capsulotomy was performed at the anterior capsule outside the optical zone of the intraocular lens. One week later, the posterior capsule adhered to the posterior surface of the intraocular lens, and there was a significant improvement in vision compared to before the procedure.

Abstract
Objective: To explore the clinical features of programmed cell death-1 (PD-1) inhibitor-associated hypophysitis and improve the understanding of the disease. Methods: For the present retrospective case series study, the clinical data of patients with PD-1 inhibitor-associated hypophysitis who were treated at the Affiliated Hospital of Hebei University and the 3rd Hospital of Hebei Medical University from January 2020 to May 2023 were collected for analysis of clinical manifestations and prognosis. Results: Fifteen cases of PD-1 inhibitor-induced hypophysitis were included, with 13 males and 2 females. The mean age of onset was (62.1±7.5) years, and the median time of onset was 6.5 (4.7, 11.6) cycles of PD-1 inhibitor. At diagnosis, 14 patients complained of gastrointestinal symptoms, and 12 patients complained of fatigue. There were 12, 1, 1, 5, and 1 cases of hyponatremia, hypokalemia, hypoglycemia, hypotension, and fever, respectively. Secondary adrenocortical insufficiency occurred in all cases. Moreover, four patients had secondary hypothyroidism, and two patients had secondary hypogonadism. Posterior pituitary hypofunction was not found. Pituitary MRI showed one case each of vacuolar sella turcica, pituitary cystic lesion, pituitary stalk slightly shifted to the left, high metabolism in the sella turcica, and pituitary abnormal signal, while no abnormalities were found in 11 cases. The follow-up time was (47.66±11.93) weeks. At the last follow-up, one patient's serum levels of adrenocorticotropic hormone and cortisol returned to normal. Conclusions: Hypophysitis associated with PD-1 inhibitors occurs later, and gastrointestinal symptoms and fatigue are the most common clinical manifestations. PD-1 inhibitor-associated hypophysitis mainly manifests as adrenocortical hypofunction, and some cases manifest as hypothyroidism and hypogonadism. In addition, patients with PD-1 inhibitor-associated hypophysitis show no obvious imaging changes in the pituitary gland.

Abstract
Objective: To summarize the clinical characteristics and gene variants of 2 pedigrees of non-muscle myosin heavy chain 9 related diseases (MYH9-RD) in children. Methods: The basic information, clinical features, gene variants and laboratory tests of MYH9-RD patients from 2 pedigrees confirmed in the First Affiliated Hospital of Zhengzhou University in November 2021 and July 2022 were analyzed retrospectively. "Non-muscle myosin heavy chain 9 related disease" "MYH9" and "children" were used as key words to search at Pubmed database, CNKI and Wanfang database up to February 2023. The MYH9-RD gene variant spectrum and clinical data were analyzed and summarized. Results: Proband 1 (male, 11 years old) sought medical attention due to epistaxis, the eldest sister and second sister of proband 1 only showed excessive menstrual bleeding, the skin and mucous membrane of the their mother were prone to ecchymosis after bumping, the uncle of proband 1 had kidney damage, and the maternal grandmother and maternal great-grandmother of proband 1 had a history of cataracts. There were 7 cases of phenotypic abnormalities in this pedigree. High-throughput sequencing showed that the proband 1 MYH9 gene had c.279C>G (p.N93K) missense variant, and family verification analysis showed that the variant was inherited from the mother. A total of 4 patients including proband 1 and family members were diagnosed with MYH9-RD. The proband 2 (female, 1 year old) sought medical attention duo to fever and cough, and the father's physical examination revealed thrombocytopenia. There were 2 cases of phenotypic abnormalities in this pedigree. High-throughput sequencing showed that there was a c.4270G>A (p.D1424N) missense variant in the proband 2 MYH9 gene, and family verification analysis showed that the variant was inherited from the father. A total of 2 patients including proband 2 and his father were diagnosed with MYH9-RD. A total of 99 articles were retrieved, including 32 domestic literatures and 67 foreign literatures. The MYH9-RD cases totaled 149 pedigrees and 197 sporadic patients, including 2 pedigrees in our study. There were 101 cases with complete clinical data, including 62 sporadic cases and 39 pedigrees. There were 56 males and 45 females, with an average age of 6.9 years old. The main clinical manifestations were thrombocytopenia, skin ecchymosis, and epistaxis. Most patients didn't receive special treatment after diagnosis. Six English literatures related to MYH9-RD caused by c.279C>G mutation in MYH9 gene were retrieved. Italy reported the highest number of cases (3 cases). Twelve literatures related to MYH9-RD caused by c.4270G>A mutation in MYH9 gene were retrieved. China reported the highest number of cases (9 cases). Conclusions: The clinical manifestations of patients in the MYH9-RD pedigrees varied greatly. MYH9 gene c.279C>G and c.4270G>A mutations are the cause of MYH9-RD.

Abstract
Objective: To evaluate the clinical outcomes and safety of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) using a conditioning regimen based on total body irradiation (TBI) and rabbit anti-human thymocyte globulin (rATG) in the management of chemotherapy-resistant advanced peripheral T-cell lymphoma (PTCL) . Methods: Clinical data of 11 patients with chemotherapy-resistant advanced PTCL who underwent haplo-HSCT with a TBI+rATG-based conditioning regimen at the Department of Hematology, Shanghai Liquan Hospital and Shanghai Zhaxin Integrated Traditional Chinese and Western Medicine Hospital, from September 2019 to December 2022 were retrospectively analyzed. Results: ①Among the 11 patients (six males and five females), with a median age of 40 years (range: 22-58 years), there were six cases of PTCL, not otherwise specified (PTCL-NOS), three cases of angioimmunoblastic T-cell lymphoma (AITL), one case of large-cell transformation of mycosis fungoides (MF-LCT), and one case of T-cell large granular lymphocytic leukemia (T-LGLL). According to the Lugano staging system, all patients were in stage Ⅲ or Ⅳ, and eight patients had B symptoms. Before transplantation, the median number of prior lines of chemotherapy was 4 (range: 2-10), and all patients had progressive disease (PD). The median time from diagnosis to transplantation was 17 months (range: 6-36 months). ②The conditioning regimen consisted of a TBI dose of 10 Gy, administered at 2 Gy on day -8 and 4 Gy from day -7 to day -6, rATG was administered at a daily dose of 2.5 mg/kg from day -5 to day -2. Etoposide (VP-16) was given at a dose of 15 mg/kg/d from day -5 to day -4, while cyclophosphamide (CTX) was administered at a dose of 50 mg/kg/d from day -3 to day -2. In patients with central nervous system involvement, etoposide and cyclophosphamide were replaced with thiotepa (TT) at a dose of 5 mg/kg/d from day -5 to day -4. Additionally, cytarabine (Ara-C) was added at a dose of 2.0 g/m(2) twice a day from day -3 to day -2 into the conditioning. ③Successful engraftment was achieved in all patients, with a median time to neutrophil engraftment of 14.5 d (range: 11-16 d) and a median time to platelet engraftment of 13 days (range: 8-18 days). Acute graft-versus-host disease (aGVHD) occurred in one patient (grade Ⅰ-Ⅱ), and another patient experienced grade Ⅲ-Ⅳ aGVHD. Among the eight survivors, four developed chronic GVHD (cGVHD). ④Post-transplantation, nine patients achieved complete response (CR). ⑤Hematopoietic suppression occurred in all patients after conditioning, with three experiencing diarrhea, four developing mucositis, three exhibiting elevated transaminase/bilirubin levels, and seven developing infectious complications. These non-hematologic adverse events were effectively managed. ⑥At one year post-transplantation, the non-relapse mortality (NRM) was (22.5±14.0) %, the cumulative incidence of relapse (CIR) was (20.2±12.7) %, and overall survival (OS) rate was (72.7±13.4) %, and disease-free survival (DFS) rate was (63.6±14.5) % . Conclusion: TBI+rATG-based conditioning regimen for haplo-HSCT is an effective and safe treatment approach for patients with chemotherapy-resistant advanced PTCL.

Abstract
OBJECTIVE The aim of this study was to construct a competent model that can effectively predict the prognosis of patients with gastric carcinoid (GC) or neuroendocrine carcinoma (NEC). PATIENTS AND METHODS Data of patients with GC or NEC were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2017. Univariable and multivariable Cox analysis was used to determine the independent factors for patients with GC or NEC. Nomograms were established based on the independent factors and the results were evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). RESULTS A total of 214 patients with GC and 65 patients with gastric NEC were extracted from the SEER database. Independent prognostic factors for patients with GC were M stage, gender, age, and chemotherapy. Independent prognostic factors for patients with gastric NEC included age, M stage, and chemotherapy. ROC curves, calibration curves, and DCA confirmed that the nomograms can precisely predict the prognosis of patients with GC and NEC. CONCLUSIONS The nomograms can effectively predict survival in patients with GC or NEC, which may assist the clinician in their decision-making and quantitatively judge the prognosis of individual patients.

Abstract
Dry/wet cycling driven by water level fluctuation in wetlands may strongly influence the destiny of seeds. However, how dry/wet cycling affects spore survival and germinability in peatland bryophytes is poorly understood. Six peatland bryophytes, three hummock- and three hollow-dwelling Sphagnum species, were chosen as study species. We tested the effects of dry (60% air RH)/wet (waterlogging) cycle frequency (once per 12, 8 or 4 days for low, medium or high, respectively) and ratio (3:1, 1:1 or 1:3 dry:wet time per cycle) on spore germinability, viability, dormancy percentage and protonema development. Dry/wet cycling significantly reduced spore germination percentage and viability and slowed protonema development in all Sphagnum species, being more pronounced with higher dry/wet cycling frequencies. The hummock species S. capillifolium and S. fuscum had higher spore germination percentage after the continuous dry treatment, while the hollow species S. angustifolium, S. squarrosum and S. subsecundum showed the opposite response, compared to the continuously wet treatment. Except for S. squarrosum, spore viability was higher after the dry than after the wet treatment. Spore viability and dormancy percentage were higher after a dry/wet ratio of 1:3 than after ratios of 3:1 and 1:1. Our study shows that both germinability and viability of bryophyte spores are reduced by dry/wet cycling (especially when frequent) in peatlands. This emphasizes the need to ensure constant water levels and low frequencies of water level fluctuation, which are relevant in connection with wetland restoration, to promote Sphagnum spore survival and establishment in peatlands after disturbances.

Abstract
OBJECTIVE This study aimed to investigate the relationship between baseline atherogenic index of plasma (AIP) and new-onset myocardial infarction (MI) in hypertensive patients with obstructive sleep apnoea (OSA). PATIENTS AND METHODS 2,281 participants were included in this analysis after strict adherence to the inclusion and exclusion criteria. Hazard ratio (HR) and 95% confidence interval (CI) were estimated using multivariable Cox regression models. A generalized additive model was employed to determine nonlinear relationships. RESULTS In multivariate-adjusted models, there was a positive association between AIP and new-onset MI (per SD increase; HR=1.42, 95% CI: 1.22-1.65). Smoothing curve fitting revealed a J-shaped association between AIP and new-onset MI, with a turning point of approximately -0.08. The addition of AIP to a model with established risk factors improved the C-index (p=0.007), integrated discrimination improvement (p=0.007), and continuous net reclassification improvement (p=0.027) for the new-onset MI. CONCLUSIONS A J-shaped relationship was observed between AIP and new-onset MI.

A total of 67 patients with anterior segment infection (33 cases of conjunctivitis, 6 cases of bacterial keratitis, 7 cases of blepharitis, 9 cases of neonatal dacryocystitis, 9 cases of neonatal dacryocystitis, 1 case of adult dacryocystitis and 11 cases of other infectious eye diseases) were collected from the conjunctival sac, cornea, eyelid margin and lacrimal sac. Minimum inhibitory concentration (MIC) determination of methicillin-resistant Staphylococcus (MRS) strains and β-lactamase-producing (β-Lac) strains by a micro-liquid-based method, according to the M100 standard of the American Institute for Clinical and Laboratory Standardization Susceptibility and resistance determinations were made. Data were statistically analyzed using Chi-square or Fisher's exact test. Results: Thirty-five MRS, 30 β-Lac and 2 β-Lac MRS isolates were identified from 67 multidrug-resistant Staphylococcus . There were 3, 9, 4, and 19 MRS isolates isolated from the lacrimal sac, cornea, eyelid margin and conjunctival sac, accounting for 3/4, 9/12, 4/8, 19/43 (44.2%) of the isolated sites respectively. There were 1, 3, 3, and 23 β-Lac isolates, accounting for 1/4, 3/12, 3/8 and 23/43 (53.5%) of the isolated sites, respectively. The highest proportion of β-Lac isolates isolated from patients with a diagnosis of conjunctivitis was 17 (25.3%) from the conjunctival sac. Among the MRS strains isolated from the cornea and lacrimal sac, 5 (7.5%) and 3 (4.5%) were from patients diagnosed with bacterial keratitis and neonatal tear, respectively. The number of MRS strains and β-Lac isolates isolated from patients with a diagnosis of blepharitis were both 3 (4.5%) from the lid margin.Among the strains isolated from the eyelid margin and the conjunctival sac, drug-resistant Staphylococcus epidermidis was the main strain, the drug-resistant Staphylococcus aureus was the major isolates in lacrimal sac and cornea. Among the 35 MRS isoaltes, 25, 24, 12, 12, and 11 were sensitive to cefazolin sodium, fusidic acid, levofloxacin, clindamycin and tobramycin, and the sensitivity rates were 71.4%, 68.6%, 34.3%, 34.3% and 31.4%, the difference was statistically significant (χ2=22.756, P<0.001), The sensitivity rates of levofloxacin, tobramycin, cefazolin sodium, fusidic acid and clindamycin against MRS isolates from the anterior segment were both statistically significant differences (χ2=18.493, 11.594, 8.906, 9.841, 16.059; all P<0.05). The susceptibility rates of MRS isolates against five antibiotics was statistically significant differences (χ2=33.080, P<0.001). Among the 30 β-Lac isolates, 27, 22, 19, 16, and 8 were sensitive to cefazolin sodium, fusidic acid, levofloxacin, tobramycin and clindamycin, and the sensitivity rates were 90.0 % , 73.3%, 63.3%, 53.3% and 26.7%, the difference was statistically significant (χ2=28.280, P<0.001). The sensitivity rates of five antibiotics against β-Lac isolates from the anterior segment were both statistically significant differences (χ2=50.971, 24.543, 48.147, 44.899, 18.676; all P<0.001). The susceptibility rates of β-Lac isolates against five antibiotics was statistically significant differences (χ2=23.383, P<0.001). The sensitivity of cefazolin sodium and fusidic acid against β-Lac isolates were higher than MRS isolates. Conclusions: Cefazolin sodium and fusidic acid may be the best choice for the treatment of drug-resistant Staphylococcus isolated from anterior conjunctival sac, cornea, eyelid margin and lacrimal sac, especially for β-Lac-producing drug-resistant Staphylococcus infection.

Abstract
Objective: To study the effects of Homeobox C10 (HOXC10) on biological characteristics such as migration, invasion and proliferation of glioma cancer cells and to explore the role of HOXC10 gene in glioma microenvironment. Methods: The expression level of HOXC10 in high grade glioma (glioblastoma) and low grade glioma and its effect on patient survival were analyzed by using The Cancer Genome Atlas (TCGA) and Chinese Glioma Genome Atlas (CGGA) database. Hoxc10-siRNA-1, HOXC10-siRNA-2 and siRNA negative control (NC) were transfected into U251 cells according to the operation instructions of HOXC10-siRNA transfection. 100 ng/ mL recombinant protein chemokine ligand 2 (reCCL2) was added into the transfection group, and was labeled as HOXC10-siRNA-1+ reCCL2 and HOXC10-siRNA-2+ reCCL2 groups. The expressions of HOXC10 mRNA and target protein in each group was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and western blot. The proliferation ability of cells in each group was detected by cell counting kit 8 (CCK8) method. The migration ability of cells was detected by Transwell assay and Nick assay, and cell apoptosis was detected by flow cytometry. The expression of chemokines in each group was detected by multiple factors. Co-incubation assays were performed to determine the role of HOXC10 and chemokine ligand 2 (CCL2) in recruiting and polarizing tumor-associated macrophages (M2-type macrophages). Results: The median expression level of HOXC10 in high grade gliomas was 8.51, higher than 1.00 in low grade gliomas (P<0.001) in TCGA database.

The expressions of vimentin in HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (141 740.00±34 024.56) and (94 655.00±5 687.97), N-cadherin were (76 810.00±14.14) and (94 254.00±701.45), β-catenin were (75 786.50±789.84) and (107 296.50±9 614.53), lower than (233 768.50±34 114.37), (237 154.50±24 715.50) and (192 449.50±24 178.10) of NC group (P<0.05). The A value of HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (0.44±0.05) and (0.32±0.02) at 96 hours, lower than 0.92±0.12 of NC group (P<0.05). The apoptosis rates of HOXC10-siRNA-1 group and HOXC10 siRNA-2 group were (10.23±1.24)% and (13.81±2.16)%, higher than (4.60±0.07)% of NC group (P<0.05). The expression levels of CCL2 in U251 cells in HOXC10-siRNA-1 and HOXC10-siRNA-2 groups were (271.63±44.27) and (371.66±50.21), lower than (933.93±29.84) in NC group (P<0.05). The expression levels of CCL5 (234.81±5.95 and 232.62±5.72), CXCL10 (544.13±48.14 and 500.87±15.65) and CXCL11 (215.75±15.30 and 176.18±16.49) in HOXC10-siRNA-1 and HOXC10-siRNA-2 groups were higher than those in NC group (9.98±0.71, 470.54±18.84 and 13.55±0.73, respectively, P<0.05). The recruited numbers of CD14(+) THP1 in HOXC10-siRNA-1 and HOXC10-siRNA-2 groups were (159.33±1.15) and (170.67±1.15), respectively, lower than (360.00±7.81) in NC group (P<0.05), while addition of reCCL2 promoted the recruitment of CD14(+) THP1 cells (287.00±3.61 and 280.67±2.31 in HOXC10-siRNA-1+ reCCL2 group and HOXC10-siRNA-2+ reCCL2 group, respectively, P<0.05). The expressions level of M2-type macrophage-related gene TGF-β in HOXC10-siRNA-1 group and HOXC10-siRNA-2 group were (0.30±0.02) and (0.28±0.02), respectively, lower than (1.06±0.10) in NC group (P<0.05). The expressions level of M1-related gene NOS2 in HOXC10-siRNA-1 and HOXC10-siRNA-2 were (11 413.95±1 911.85) and (5 894.00±945.21), respectively, higher than (13.39±4.32) in NC group (P<0.05). Conclusions: The expression of HOXC10 in glioma is high and positively correlated with the poor prognosis of glioma patients. Knockdown of HOXC10 can inhibit the proliferation, migration and metastasis of human glioma U251 cells. HOXC10 may play an immunosuppressive role in glioma microenvironment by promoting the expression of CCL2 and recruiting and polarizing tumor-associated macrophages (M2 macrophages).

Abstract
To explore the biofilm inhibitory efficacy of perifosine against Pseudomonas aeruginosa (P. aeruginos) and its mechanisms. Twenty-fourwell plate was used to form biofilms at the bottom and crystal violet staining was used to determine the biofilm inhibitory effects of perifosine against P. aeruginosa, the wells without perifosine was set as control group. Glass tubes combined with crystal violet staining was used to detect the gas-liqud interface related bioiflm inhibitory effects of perifosine, the wells without perifosine was set as control group. Time-growth curved was used to detect the effects of perifosine on the bacteial planktonic cells growth of P. aeruginosa, the wells without perifosine was set as control group. The interaction model between perifosine and PqsE was assessed by molecular docking assay. The inhibitory effects of perifosine on the catalytic activity of PqsE was determined by detection the production of thiols, the wells without perifosine was set as control group. Binding affinity between perifosine and PqsE was detected by plasma surface resonance. The biofims at the bottom of the microplates and air-liquid interface were effectively inhibited by perifosine at the concentration of 4-8 μg/ml. There was no influence of perifosine on the cells growth of P. aeruginosa. The resuts of molecular docking assay indicates that perifosine could interacted with PqsE with the docking score of -10.67 kcal/mol. Perifosine could inhibit the catalytic activity of PqsE in a dose-dependent manner. The binding affinity between perifosine and PqsE was comfirmed by plasma surface resonance with KD of 6.65×10-5mol/L. Perifosine could inhibited the biofilm formation of P. aeruginosa by interacting with PqsE.

Abstract
Objective: To explore the clinical application value of MRI-PDFF on different liver segments for the evaluation of non-alcoholic fatty liver disease (NAFLD). Methods: 178 volunteers from March 2019 to February 2020 were included. PDFF values of all nine segments of the liver were measured using CSE3.0T MRI scan. The obtained average value was used to represent the average liver fat content. PDFF values of each or combined liver segment were equally compared with the average value to observe the representativeness of fat content. Receiver operating characteristic curve was used to analyze the diagnostic performance of each liver segment, and the Youden index was used to calculate the cutoff value. Paired-sample t-test or non-parametric Kruskal-Wallis test were used to compare measurement data among groups. Results: 178 volunteers average liver fat content ranged from 0.89% to 42.61% with MRI-PDFF, and 71.35% (127/178) of the volunteers had PDFF > 5%. There was no significant difference between SIII, SIVb, SV, and SVIII liver segments when compared with the average value (P > 0.05). PDFF values of SI, SII, and SIV a liver segments were all lower than the average value, while the PDFF values of SVI and SVII liver segments were all higher than the average value (P < 0.05). MRI-PDFF sensitivity value for diagnosing liver steatosis of nine liver segments was 85.8% ~ 94.5%, and the specificity was higher than 96.0%. Among them, the SV liver segment had the highest sensitivity (94.5%), and the corresponding optimal diagnostic threshold value was 5.13%. Compared with single and combined liver segment, the PDFF value of SII, SV, SVI combined liver segment had the highest diagnostic performance for fatty liver, with the sensitivity and specificity of 96.9%, and 100%, respectively, and the corresponding optimal diagnostic threshold value was 5.17%. Conclusion: Compared with single and other combined liver segments, MRI-PDFF values of SII, SV, and SVI combined liver segments have higher sensitivity and specificity for the diagnosis of NAFLD, and it can be used as the first choice for the determination of liver fat content with MRI.

Abstract
Objective: To investigate the relationship between the angiotensinogen (AGT) rs5051 single nucleotide polymorphism (SNP) and the onset risk of coronary heart disease (CHD) in patients with non-alcoholic fatty liver disease (NAFLD) in the Han Chinese population. Methods: A total of 454 subjects were enrolled in this study. Among them, 140 cases were with NAFLD, 112 cases with NAFLD combined with CHD, and 202 healthy controls. Blood samples of all subjects were examined for biochemical indexes. Genotype at AGT rs5051 locus was detected by polymerase chain reaction. SPSS 21.0 statistical software was used for data statistical analysis. Results: The differences in distribution of AGT rs5051 genotypes and alleles between the NAFLD and the control group were not statistically significant (P > 0.05). The differences in the distribution of AGT rs5051 genotypes and alleles between the NAFLD combined with CHD and the NAFLD group were statistically significant (χ(2) = 10.32, P = 0.001; χ(2) = 11.72, P < 0.001). Binary logistic regression analysis results showed that TC + CC genotype had increased the occurrence risk of CHD in NAFLD patients (OR = 2.203, 95% CI: 1.322 ~ 3.670, P = 0.02) than AGT rs5051 TT genotype carriers. After adjusting for gender, age, and body mass index, the TC + CC genotype still significantly increased the occurrence risk of CHD in NAFLD patients (OR = 2.378, 95% CI: 1.384 ~ 4.087, P = 0.02). In addition, AGT rs5051 C allele mutations had significantly increased the occurrence risk of CHD in patients with NAFLD (OR = 2.018 before adjustment, 95% CI: 1.345 ~ 3.027, P = 0.001; OR = 2.161, 95% CI: 1.406 ~ 3.322 after adjustment. P < 0.001). Conclusion: This study is the first to report the correlation between AGT rs5051 polymorphism and the occurrence risk of CHD in patients with NAFLD in Han Chinese population. AGT rs5051 polymorphism can significantly increase the risk of CHD in patients with NAFLD.

Abstract
Objective: To construct a transmembrane 6 superfamily member 2 (Tm6sf2) E167K gene knock-in mouse model. Methods: The plasmid was constructed to simultaneously express the single-stranded guide RNA Cas9 at a specific site of the mouse Tm6sf2 gene in the donor plasmid carrying the Tm6sf2 E167K fragment. The above two plasmids were injected into the mouse fertilized eggs together. The positive F0 generation mice were validated by PCR detection and sequencing. The number of F2 generation surviving mice in three genotypes of wild (Wt), heterozygous and knock-in (KI) were calculated. Wt and KI male mice (8 mice/ group) of F2 generation littermates were selected and given a normal diet for 8 weeks. The body weight of the mice was recorded every week, and the glucose metabolism and lipid metabolism indexes of the two mice were detected. The comparison between groups was performed with an independent sample t-test. Results: Genotype detection and sequencing results showed that the Tm6sf2 E167K gene knock-in mouse model was successfully established. KI mice had absence of homozygous lethal embryo phenotype. The body weight of KI mice was higher than that of Wt mice during lactation, and the difference between the two groups was statistically significant (P < 0.05).The fasting blood glucose of KI mice (9.50 ± 0.33)mmol/L was higher than that of Wt mice (7.80 ± 0.30)mmol/L, and the difference between the two groups was statistically significant (P < 0.05). During the oral glucose tolerance test, the 2-hour blood glucose level of KI mice (9.20 ± 0.51)mmol/L was higher than that of Wt mice (7.60 ± 0.18)mmol/L, and the difference between the two groups was statistically significant (P < 0.05). The liver triglyceride content of KI mice (8.40 ± 0.55)mg/g was higher than that of Wt mice (7.30 ± 0.63)mg/g, but the difference was not statistically significant (P > 0.05). There was no significant difference in plasma triglyceride levels between the two mice (P > 0.05). The Oil red O staining results showed that KI mice had more lipid accumulation in the centrilobular region of liver than Wt mice. Conclusion: Tm6sf2 E167K gene knock-in mice were successfully constructed. Tm6sf2 E167K gene knock-in can cause abnormal glucose metabolism in mice and promote the occurrence of hepatic steatosis.

Abstract
Objective: To explore the effect of smoking on the wound healing of stage 4 pressure ulcers in rats. Methods: Fifty male Sprague-Dawley rats aged 6-8 weeks were divided into simple pressure ulcer group and smoking+ pressure ulcer group according to the random number table, with 25 rats in each group. After the rats in the smoking+ pressure ulcer group received passive smoking intervention for 12 weeks, an iron plate was placed in the back muscle of each rat in 2 groups, and a magnet was placed outside the skin at the corresponding position of the iron plate for 2 h at each time, with 5 times a day and continuously for 6 days to reproduce stage 4 pressure ulcer model. Immediately after establishing the model, 3 rats in each group were sacrificed and wound tissue was collected, and hematoxylin-eosin staining was applied to observe the pathological changes of the wounds. On 1, 3, 7, and 14 day (s) after establishing the model, 3 rats in each group were collected to measure the pressure ulcer wound area by the paper jam method. After measurement of the wound area, the rats were sacrificed and the wound tissue was collected, and the protein expression levels of matrix metalloproteinases 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) in wound tissue were detected by immunohistochemical method, and the ratio of MMP-9/TIMP-1 was calculated.The wound healing time of the remaining 10 rats in each group was recorded. Data were statistically analyzed with analysis of variance for factorial design, two independent sample t test, and Bonferroni correction. Results: (1) Immediately after establishing the model, muscle fiber necrosis and dissolution with large areas were seen on the wound, the myofibrils arranged loosely, and more lymphocytes and monocytes infiltration were seen around the wound of rats in simple pressure ulcer group. A large number of necrotic myofibers were dissolved and gradually disappeared, the myofibrils arranged loosely, and the number of diffuse lymphocytes and monocyte infiltration in wound of rats in smoking+ pressure ulcer group were significantly higher than those in simple pressure ulcer group. (2) The wound areas of rats in smoking+ pressure ulcer group were significantly larger than those in simple pressure ulcer group on 1, 3, 7, and 14 day (s) after establishing the model (t=3.019, 2.549, 2.181, 3.674, P<0.05 or P<0.01). (3) On 1 to 14 days after establishing the model, the protein expression levels of MMP-9 and TIMP-1 in the wound tissue and the ratio of MMP-9/TIMP-1 of rats in the two groups increased first and then decreased. On 1, 3, 7, and 14 day (s) after establishing the model, the protein expression levels of MMP-9 in the wound tissue and the ratio of MMP-9/TIMP-1 of rats in smoking+ pressure ulcer group were significantly higher than those in simple pressure ulcer group (t=4.783, 4.508, 6.325, 7.204, 3.078, 2.989, 4.081, 4.696, P<0.05 or P<0.01), and the protein expression levels of TIMP-1 in wound tissue of rats in the two groups were similar. (4) The wound healing time of rats in smoking+ pressure ulcer group was (48.9±2.6) d, which was significantly longer than (35.2±2.3) d of simple pressure ulcer group (t=12.477, P<0.05). Conclusions: Smoking can up-regulate the expression of MMP-9 in pressure ulcer wound and result in an imbalance of MMP-9/TIMP-1, thereby affecting the wound healing of stage 4 pressure ulcers in rats.

Abstract
Objective: To understand the detection of group A rotavirus (RVA) in domestic sewage and its molecular epidemiological characteristics, and further explore the feasibility and necessity of RVA environmental surveillance. Methods: From 2016 to 2018, we collected domestic sewage samples monthly in Jinan city, and concentrated them via anion membrane adsorption-elution method. Then RNA extraction and RVA VP7 and VP4 coding region RT-PCR amplification were performed. After purification, TA cloning and sequencing, homology analysis and phylogenetic analysis were conducted on the obtained sequences. Results: RVA G gene was detected in 31 of the 36 sewage samples (86.1% detection rate); RVA P genotype was detected in 33 samples (91.7% detection rate). A total of 536 RVA sequences were obtained, of which 225 G-type sequences belonged to 6 genotypes, and the G9 accounted for 92.4% (208/225); 311 P-type sequences were obtained, which belonged to 4 genotypes. The dominant P[8] accounted for 50.1% (156/311), followed by P[4] with 41.8% (130/311). Phylogenetic analysis shows that there were multiple transmission chains circulating in the dominant genotypes G9 and P[8]. Conclusion: The genotype, homology, and phylogenetic characteristics of sequences obtained from domestic sewage in Jinan area were described, which further confirmeing that RVA environmental surveillance is not feasible but also necessary.

Abstract
Ovarian cancer (OC) is one of the most common gynecological malignancies, with the highest mortality rate in women worldwide. LINC00662, a long non-coding RNA (lncRNA), was shown to play a vital role in many malignancies, while little is known about its role in OC. Firstly, our study determined the expression of LINC00662 in OC tissues and cells. Upregulation or downregulation of LINC00662 were performed in OC cells to explore its effects on cell proliferation and glycolysis of OC. The interaction between LINC00662 and miR-375 was verified using luciferase assays and RNA immunoprecipitation. Results showed that LINC00662 was highly expressed in OC tissues and cells, and patients with increased expression of LINC00662 were associated with shorter overall survival. Furthermore, functional assays proved that LINC00662 was essential for OC cell proliferation and glycolysis. Subsequently, our study further revealed that LINC00662 acted as a competitive RNA and it could modulate the expression of HIF-1α through directly binding with miR- 375. Collectively, upregulation of LINC00662 in ovarian cancer tissues is closely correlated to poor survival. LINC00662 might regulate HIF-1α expression via miR-375. These findings suggested that LINC00662 has the potential to be explored as a diagnostic biomarker for OC.

Abstract
Objective: To investigate the in vitro antibacterial sensitivity of levofloxacin, tobramycin, cefazolin sodium, clindamycin and fusidic acid to 67 strains of Staphylococci in ocular surface infection. The purpose of this study is to provide reference for clinical selection of drugs. Methods: Experimental study. Sixth-seven strains of drug-resistant Staphylococci isolated from the Department of Microbiology, Henan Provincial Ophthalmic Hospital during January 2018 and May 2019 were collected. There were 67 strains of Staphylococci including 28 strains of drug-resistant Staphylococcus epidermidi, 17 strains of drug-resistant Staphylococcus aureus, 15 strains of drug-resistant Staphylococcus intermedius and a few other kinds of drug-resistant Staphylococci. The minimum inhibitory concentrations (minimum inhibitory concentration, MIC) of levofloxacin, tobramycin, cefazolin sodium, clindamycin and fusidic acid in 67 strains of drug-resistant Staphylococci were determined by microliquid-based method. The sensitivity was determined according to the American CLSI-M100 standard. The statistical analysis of the data was carried out by using two-dimensional test and Fisher accurate test. Results: Fourteen strains of fusidic acid were sensitive to 17 strains of MRS-Meca-resistant Staphylococcus epidermidis, the difference between fusidic and levofloxacin is statistically significant; 14 strains of cefazolin sodium and 11 strains of fusidic acid were sensitive to 14 strains of β-Lac enzyme-producing Staphylococcus aureus, and there were significant differences between the two drugs and levofloxacin; 6 strains of cefazolin sodium and 5 strains of fusidic acid were sensitive to 10 strains of MRS-Meca-resistant Staphylococcus intermedius, as compared to levofloxacin, there were significant differences between cefazolin sodium and levofloxacin (P=0.011,0.033). Cefazolin sodium was sensitive to 5 strains of MRS-Meca-positive other drug-resistant Staphylococci, which was significantly different from levofloxacin (P=0.048); 54 and 48 strains of cefazolin sodium and fusidic acid were sensitive to 67 strains of drug-resistant Staphylococci, and the sensitive rates were 80.1% and 71.6%, respectively, which were significantly higher than those of levofloxacin, tobramycin and clindamycin. There were significant statistical differences between drug sensitivity (χ²=18.377,9.940;P=0.000,0.003). Conclusions: The sensitivity of cefazolin sodium and fusidic acid to 67 strains of drug-resistant Staphylococci is better than that of levofloxacin, tobramycin and clindamycin, these findings may provide guidance for the clinical treatment of drug-resistant Staphylococci in ocular infection.

Abstract
Objective: To explore the feasibility of using faster regional convolutional neural network (Faster R-CNN) to evaluate the status of circumferential resection margin (CRM) of rectal cancer in the magnetic resonance imaging (MRI). Methods: This study was registered in the Chinese Clinical Trial Registry (ChiCTR-1800017410). Case inclusion criteria: (1) the positive area of CRM was located between the plane of the levator ani, anal canal and peritoneal reflection; (2) rectal malignancy was confirmed by electronic colonoscopy and histopathological examination; (3) positive CRM was confirmed by postoperative pathology or preoperative high-resolution MRI. Exclusion criteria: patients after neoadjuvant therapy, recurrent cancer after surgery, poor quality images, giant tumor with extensive necrosis and tissue degeneration, and rectal tissue construction changes in previous pelvic surgery. According to the above criteria, MRI plain scan images of 350 patients with rectal cancer and positive CRM in The Affiliated Hospital of Qingdao University from July 2016 to June 2019 were collected. The patients were classified by gender and tumor position, and randomly assigned to the training group (300 cases) and the validation group (50 cases) at a ratio of 6:1 by computer random number method. The CRM positive region was identified on the T2WI image using the LabelImg software. The identified training group images were used to iteratively train and optimize parameters of the Faster R-CNN model until the network converged to obtain the best deep learning model. The test set data were used to evaluate the recognition performance of the artificial intelligence platform. The selected indicators included accuracy, sensitivity, positive predictive value, receiver operating characteristic (ROC) curves, areas under the ROC curves (AUC), and the time taken to identify a single image. Results: The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the CRM status determined by the trained Faster R-CNN artificial intelligence approach were 0.884, 0.857, 0.898, 0.807, and 0.926, respectively; the AUC was 0.934 (95% CI: 91.3% to 95.4%). The Faster R-CNN model's automatic recognition time for a single image was 0.2 s. Conclusion: The artificial intelligence model based on Faster R-CNN for the identification and segmentation of CRM-positive MRI images of rectal cancer is established, which can complete the risk assessment of CRM-positive areas caused by in-situ tumor invasion and has the application value of preliminary screening.

Abstract
Objective: To explore the occurrence of cognitive impairment in Chinese heart failure (HF) patients and it's impact on prognosis. Methods: In this prospective observational study, a total of 990 HF patients were enrolled from 24 hospitals in China during December 2012 to November 2014. All patients were administrated with the interview-format Montreal Cognitive Assessment (MoCA), according to which they were divided into MoCA<26 (with cognitive impairment) group and MoCA≥26 (without cognitive impairment) group. Baseline data were collected and a 1-year follow up was carried out. Univariate and multivariate logistic or Cox regression were performed for 1-year outcomes. Results: Cognitive impairment was evidenced in 628 patients (63.4%) and they were more likely to be older, female, and with higher proportion of New York Heart Association(NYHA) class Ⅲ-Ⅳ, chronic obstructive pulmonary disease (COPD), ischemic heart disease, while body mass index (BMI), education level, and medical insurance rate were lower (all P<0.05) as compared to patients in MoCA≥26 group. The rate of percutaneous intervention, device implantation, cardiac surgery and evidence-based medications were significantly lower in MoCA<26 group than in MoCA≥26 group (all P<0.05). During the 1-year follow up, patients in the MoCA<26 group had higher all-cause mortality (10.2%(64/628) vs. 2.2%(8/362), P<0.01), cardiovascular mortality (5.9%(37/628) vs. 0.8%(3/362), P<0.01) and major adverse cardiac and cerebrovascular events (MACCE) (9.6%(60/628) vs. 2.5%(8/362), P<0.01) than patients in the MoCA≥26 group. In univariate regression, MoCA<26 was associated with increased all-cause mortality (HR(95%CI):4.739(2.272-9.885), P<0.01), cardiovascular mortality (HR(95%CI):7.258(2.237-23.548), P=0.001) and MACCE (OR(95%CI):4.143(2.031-8.453), P<0.01). After adjustment by multivariate regression, MoCA<26 was indicated as an independent risk factor for all-cause mortality (HR(95%CI): 6.387(2.533-16.104), P<0.01), cardiovascular mortality (HR(95%CI): 10.848(2.586-45.506), P=0.001) and MACCE (OR(95%CI): 4.081(1.299-12.816), P=0.016), while not for re-hospitalization for HF (OR(95%CI):1.010(0.700-1.457), P=0.957). Conclusions: Cognitive impairment is common in HF patients,and it is an independent prognostic factor for 1-year outcomes. Routine cognitive function assessment and active intervention are thus recommended for HF patients.

Abstract
The majority of cervical spine injuries in children occur in the upper cervical spine, of which odontoid fracture is the most common. Odontoid fracture in children is a very insidious injury. Due to the unclear language and incompatible physical examination, the disease is often missed diagnosis. Because the child axis is still in the developmental segment, including 4 synchondrosis and 6 ossification centers, there are obvious anatomical and biological differences between the child odontoid fracture and the adult. Therefore, the choice of treatment is different from that of adults. This article will introduce the development of odontoid in children, and summarize the injury characteristics, clinical classification and treatment of odontoid fracture in children.

Abstract
Objective: The aim of the present study was to investigate the survival rate and its prognostic factors for patients with biliary tract cancer, and then a prognostic risk prediction model was constructed to predict the survival probability of patients. Methods: A total of 14 005 patients with biliary tract cancer (including gallbladder cancer, extrahepatic bile duct cancer, and ampulla of Vater cancer), who were diagnosed between 2010 and 2015 in the US National Cancer Institute Surveillance, Epidemiology, and End Results Program (SEER) were included in the development cohort. The prognostic risk factors of biliary tract cancer were investigated using multivariate Cox regression models. The predictive nomograms were then constructed to predict the overall survival probability of 1, 3, and 5 years, and the predictive discrimination and calibration ability of the nomograms were further evaluated. Meanwhile, 11 953 patients who were diagnosed during 2004 to 2009 from SEER Program were then selected to validate the external predictive accuracy of the prediction models. Results: The 1, 3 and 5-year cumulative survival rates of patients with biliary tract cancer were 41.9%, 20.4% and 15.3%, respectively, in the development cohort. Age greater than 50 years, African Americans and Native Americans and Alaska Natives, higher T, N and M stage and poor histological differentiation grade were risk factors for death, while married status, Asia-Pacific Islanders, insured status and surgery on primary site were protective factors. Gender was not significantly associated with the overall survival. The C statistic of the prediction model was 0.73 (95%CI: 0.72-0.74), and the calibration curve showed that the interaction curves of predictive and actual survival rates of 1, 3 and 5 years were close to the 45 degree diagonal. Results in the validation cohort were similar with those in the construction cohort, with a C statistic of 0.70 (95%CI: 0.69-0.72), indicating high external applicability of the prediction model. Findings from gallbladder cancer, extrahepatic bile duct cancer, and ampulla of Vater cancer are in consistent with the overall biliary tract cancer. Conclusions: The survival rate of patients with biliary tract cancer is relatively poor, and the survival prediction model based on prognostic factors has high prediction accuracy. In the future, this prognostic prediction model could be applied to clinical practice to guide individualized treatment for patients with biliary tract cancer.

Abstract
Meralgia paresthetica (MP) after posterior spine surgery is caused by mechanical compression injury of lateral femoral cutaneous nerve, which presents as numbness or paresthesia in the confined area of the anterolateral thigh. MP after posterior spine surgery is a common postoperative complication, and the incidence is 12.7%-25.5%. Because its clinical manifestations are mild and easy to be ignored, often leading to treatment delays. This article mainly reviews the incidence, risk factors, prevention and treatment of MP after posterior spine surgery.

Abstract
Objective: To systematically review the mortality burden study of influenza in mainland China. Method: "influenza", "flu", "H1N1", "pandemic", "mortality", "death", "fatality", "burden", "China" and "Chinese" were used as keywords, and a systematic literature search was conducted to identify articles in three English databases (PubMed, Web of Science and Embase) and three Chinese database (CNKI, WanFang and VIP) during 1990-2018 (excluding Hong Kong, Macao and Taiwan). The language of literature was restricted to Chinese and English. The inclusion criteria were human-oriented researches with method based on population, and research indexes included mortality and excess mortality. The exclusion criteria were non-primary research materials, predictive research and research on the burden of avian influenza related deaths. A total of 17 literatures were included, and the basic information to descriptive characteristics, methodology of modeling and the corresponding results were extracted. Results: All the 17 studies adopted indirect statistical models, with 14 of which adopted the regression model, and all the research index was excess mortality. All causes (16 studies), respiratory and circulatory diseases (14 studies) and pneumonia and influenza (10 studies) were the main causes of death associated with influenza. Influenza associated mortality burden in the elderly was higher, with the lowest excess mortality rates of all causes, respiratory and circulatory diseases, pneumonia and influenza being 49.57, 30.80 and 0.69 per 100 000 people, and the highest rates being 228.16, 170.20 and 30.35 per 100 000 people, respectively. In the non-elderly, the corresponding lowest rates were -0.27, -0.08 and 0.04 per 100 000 people respectively, and the highest rates were 3.63, 2.6 and 0.91 per 100 000 people, respectively. The influenza-related excess mortality was higher in the north, with a minimum of 7.8 per 100 000 and a maximum of 18.0 per 100 000, and slightly lower in the south, with a minimum of 6.11 per 100 000 and a maximum of 18.7 per 100 000. There were also differences in deaths caused by different influenza virus subtypes, with influenza A(H3N2) and influenza B virus possibly posing a heavier mortality burden. Conclusions: Studies on influenza mortality burden is mainly based on indirect model and urban level in China. The mortality burden of influenza in the elderly, the northern and subtype A(H3N2) and B were more severe.

Abstract
Objectives: To understand the status of studies about influenza economic burden in mainland China and summarize their major results. Methods: The words of influenza, flu, cost, economic, burden, effectiveness, benefit, utility, China, and Chinese, were used as search keywords. Journal papers published during 2000-2018 were searched from Chinese electronic databases (CNKI and Wanfang) and English electronic databases (PubMed, Web of science, EconLit and Cochrane Library). The language of literature was restricted to Chinese and English. A total of 23 effective documents were included, and the descriptive characteristics, research indexes and methods included in the literature were analyzed. The monetary unit used in this review is Chinese Yuan (CNY). Results: The 23 study sites were mainly in the relatively developed and populous regions. The total cost per capita of laboratory-confirmed influenza,of all age-group was reported in 6 literatures, and only 4 literatures reported it in out-patients (range: 768.0-999.9 CNY), Only one study reported this indicator in inpatients (9 832.0 CNY). One literature reported the total cost per capita of influenza-like illness,, which was 205.1 CNY. And one literature reported that the direct medical cost of inpatients per capita in children under 5 years of age was 6 072.0 CNY while two literature reported this index for the elderly over 60 years of age, ranging from 14 250.0 to 19 349.1 CNY. Four articles reported the economic burden of influenza in urban and rural areas, one of which showed that the related expenses of urban influenza inpatients accounted for 31% of the average annual income, while which for the rural flow was 113%. Conclusion: The average economic burden of lab-confirmed influenza case is higher than that of influenza-like illness, and there are differences in outpatient indirect expenses and inpatients direct medical expenses. The direct medical burden for the hospitalized 60-years-and-beyond influenza case group is heavier thar other age group. By region, the influenza associated individual economic burden in rural area is higher than that of urban area..

Abstract
Objective: To observe the cellular damage of low-dose combined exposure to Hg, Pb and Cd on hippocampal neurons in rat. Methods: SH-SY5Y cells were randomly divided into 8 groups by 2×2×2 factorial design: control group, Pb exposure group, Hg exposure group, Pb+Hg exposure group, Pb+Cd exposure group, Hg+Cd exposure group and Pb+Cd+Hg exposure group. And the cell viabilities were measured. On this basis, an animal model was established. Twenty eight-week-old SD pregnant rats were randomly divided into four groups by random number table, and five in each group: the control group(distilled water), 1-fold metal mixture exposure group (1×MM, poisoning solution containing mercury chloride 0.15 mg/L, lead acetate trihydrate 25 mg/L, cadmium chloride 7.5 mg/L), 5-fold metal mixture exposure group (5×MM, poisoning solution containing mercury chloride 0.75 mg/L, lead acetate trihydrate 125.00 mg/L, cadmium chloride 37.50 mg/L), 10-fold metal mixture exposure group (10×MM, poisoning solution containing mercury chloride 1.50 mg/L, lead acetate trihydrate 250.00 mg/L, cadmium chloride 75.00 mg/L). Pregnant rats drank water until delivery. Twenty male pups were selected and exposed to these metals through breast milk until weaned. The heavy metals dose of poisoning water was adjusted, and then the weaned rats were exposed to heavy metals via drinking poisoning water until adulthood (postnatal day 83). The blood samples and brain hippocampus samples were collected to observe the ultrastructural changes of hippocampus, and to determine the levels of Hg, Pb and Cd in blood. In addition, apoptosis rate and fluorescence intensity of reactive oxygen species and intracellular free calcium concentration ([Ca(2+)](i)) in hippocampal neurons were measured. Results: Cellular factorial design analysis showed that Hg+Pb+Cd (at no observed adverse effect level, 1.0, 0.5 and 0.1 μmol/L, respectively)had a interaction on cell viability after 48 or 72 hours of combined exposure (P<0.05). The results of ultrastructure showed that mitochondria decreased, ridges and matrixes gradually dissolved in rat hippocampal neurons of 5×MM group; nuclear chromatin aggregated, more ridges and matrixes dissolved and the mitochondria also decreased in rat hippocampal neurons of 10×MM group. The concentration of Hg, Pb and Cd in the blood of 1×MM group, 5×MM group and 10×MM group were higher than those in the control group, and the differences were statistically significant (P<0.001). There was no significant difference in apoptosis rate between the 1×MM group and the control group. The apoptosis rate of 5×MM group and 10×MM group was higher than that in the control group, and the differences were statistically significant (P<0.001). There was no statistically significant difference in the fluorescence intensity of reactive oxygen species in hippocampal neurons of the 1×MM group and the control group. The fluorescence intensity of reactive oxygen species in the 5×MM group and the 10×MM group was higher than that in the control group, the difference was statistically significant (P<0.05). There was no significant difference in the fluorescence intensity of [Ca(2+)](i) between the 1×MM group and the control group. The fluorescence intensity values of [Ca(2+)](i) in the 5×MM group and the 10×MM group were higher than the control group, the differences were statistically significant (P<0.001). Conclusion: Low-level combined exposure to Hg, Pb, and Cd caused synergistic neurotoxic damage, and the process may be related to the changes of neuronal apoptosis, reactive oxide species, and [Ca(2+)](i) levels.

Abstract
Whiteflies (Bemisia tabaci) are phloem feeders, and some invasive species are composed of cryptic species complexes that cause extensive crop damage, particularly via the direct transmission of plant viruses. Apoptosis is a type of programmed cell death essential for organismal development and tissue homeostasis. The caspases belong to a family of cysteine proteases that play a central role in the initiation of apoptosis in many organisms. Here, we employed a comprehensive genomics approach to identity caspases in B. tabaci Middle East Asia Minor 1 (MEAM1), an invasive whitefly that carries a cryptic species complex that is devastating to crops. Four caspase genes were identified, and their motif compositions were predicted. Structures were relatively conserved in both putative effector and initiator caspases. Expression patterns of caspase genes differed across insect developmental stages. Three caspase genes were induced immediately after ultraviolet (UV) treatment. Expression levels of Bt-caspase-1 and Bt-caspase-3b increased in the midgut and salivary glands during apoptosis induced by UV treatments, whereas silencing of both genes reduced UV-triggered apoptosis. Our study demonstrates that Bt-caspase-1 and Bt-caspase-3b, respectively, act as putative initiator and effector apoptotic caspases in the MEAM1 whitefly.

Abstract
OBJECTIVE Aberrant expression of miR-338-3p has recently involved in the progression and development of various types of malignant tumors, but its role in the progression of cervical cancer remains unknown. This study aims to investigate the role of miR-338-3p/MACC1 axis in the progression of cervical cancer. PATIENTS AND METHODS MiR-338-3p and metastasis-associated in colon cancer 1 (MACC1) expression was determined in cervical cancer by quantitative real-time PCR (qRT-PCR). We explored the association of miR-338-3p expression with pathology and prognosis in cervical cancer patients. We explored the function of miR-338-3p and MACC1 on cell proliferation. A luciferase reporter assay was conducted to confirm the target gene of miR-338-3p in cervical cancer cells. RESULTS In the present work, our data showed that the expression of miR-338-3p was substantially decreased in cervical cancer tissues and associated with advanced FIGO stage, lymph node metastasis, depth of cervical invasion and poor overall survival. However, the MACC1 had an opposite expression. Mechanistically, we identified that MACC1 which acted as a functional downstream target for miR-338-3p. Furthermore, overexpression of miR-338-3p decreased expression of MACC1 in cervical cancer cells could significantly inhibit cervical cancer cell proliferation and induce cells apoptosis. Interestingly, miR-338-3p and MACC1 had proven to be involved in the progression of cervical cancer cells by regulating mitogen-activated protein kinase (MAPK) signaling pathway. CONCLUSIONS Our results suggested miR-338-3p/MACC1/MAPK regulatory pathway play an important role in the progression of cervical cancer.

Abstract
Objective: To investigate the influence of thermal cycling on the mechanical properties of resin-ceramic composites. Methods: The different groups of resin-ceramic composites A (Lava Ultimate, 3M ESPE, USA), B (block HC, Shofu, Japan), C (Hyramic, Upcera, China), D (Vita Enamic, Vita, German), and the feldspar ceramic E (Mark Ⅱ, Vita, German) were included in this study. The properties of these groups (with 30 samples in each group), including flexural strength, flexural modulus and Vickers hardness were tested before and after thermal cycling (0, 10 000 and 20 000 cycles, respectively). The data were statistically analyzed. Results: Before thermal cycling, the flexural strength of groups A, B and C [(166.28±13.78) MPa, (170.21±11.36) MPa and (202.04±16.55) MPa] were higher than those of groups D and E [(137.09±8.83) MPa and (119.35±5.98) MPa], and the flexural modulus [(62.39±3.40) GPa] and Vickers hardness [(406.97±14.73) HV] of E group were higher than those of other groups (P<0.05). The flexural strength, flexural modulus and Vickers hardness of groups D and E did not change after thermal cycling (all P>0.05), while those of groups A, B and C decreased (all P<0.05). Conclusion: After thermal cycling, the mechanical properties of the A, B and C groups decreased, while those of the groups D and E were stable.

Abstract
Alzheimer disease (AD) is a progressive neurodegenerative disease and is a leading cause of dementia among elders. In the early phase of AD, even if neuropathological changes presented, but little to none clinical symptoms were found. Therefore, it is difficult to diagnose AD in the beginning of the disease. It is vital to find a noninvasive way for both diagnose and prognosis of AD. Studies have found that β-amyloid (Aβ) works as a connection between AD and cataract. This review will discuss AD and its associated markers which may be present in the lens and cataract related AD to provide more basis for early diagnosis of AD.

Abstract
The molecular mechanisms underlying regulation of vascular endothelial growth factor (VEGF) in epithelial ovarian cancer (EOC) remain poorly defined. VEGF, a potent angiogenic factor, is up-regulated in a variety of cancers and contributes to angiogenesis in tumor tissues. The level of VEGF correlates with progression of malignancy. We previously reported that miR-92 is abnormally elevated in the plasma of EOC patients. Here, we tested the hypothesis that miR-92 inhibits von Hippel-Lindau gene product (VHL), a tumor suppressor gene, and in turn de-represses HIF-1α, a known key transcription factor for VEGF, to stimulate VEGF expression. Using a variety of biomedical methods including Western blot, RT-PCR, gene silencing, luciferase assay, and chromatin immunoprecipitation in both surgically-resected specimens and EOC cell culture, we established that EOC cells have elevated levels of HIF-1α and miR-92 expression, but the expression of VHL is reduced. We further demonstrated that miR-92 can target the VHL transcript to repress its expression. We also found that stabilized HIF-1α can form an active complex with transcriptional coactivator p300 and phosphorylated-STAT3 at the VEGF promoter to stimulate its expression. In addition, matrix metalloproteinases MMP-2 and MMP-9 are positively regulated by HIF-1α. These results suggest that miR-92 can potentially be considered as a novel therapeutical target in treatment of EOS.

Abstract
Engineering a small diameter vascular graft with mechanical and biological properties comparable to living tissues remains challenging. Often, current devices lead to thrombosis and unsatisfactory long-term patency as a result of poor blood compatibility and a mismatch between the mechanical properties of the living tissue and the implanted biomaterial. Addressing all these requirements is essential to produce scaffolds able to survive throughout the life of the patient. For this purpose, we fabricated a novel three-layered vascular graft by combining electrospinning and braiding. Mirroring the structure of human blood vessels, the proposed device is composed of three layers: the intima, the media, and the adventitia. The intima and media layers were obtained by sequentially electrospinning silk fibroin (SF) and poly(L-lactide-co-ε-caprolactone), with ratios selected to match the mechanical properties of the native tissue. For the outer layer, the adventitia, SF yarns were braided on top of the electrospun tubes to create a structure able to withstand high pressures. Compliance, Young's modulus and deformability of the obtained scaffold were similar to that of human blood vessels. Additionally, cytocompatibility of the two layers, media and intima, was assessed in vitro by analysing cell metabolic activity and proliferation of endothelial cells and smooth muscle cells, respectively. Furthermore, heparin functionalization of the scaffolds led to improved anticoagulant properties upon incubation in whole blood. The obtained results indicate a potential application of the herewith designed three-layered construct as a vascular graft for small diameter blood vessel engineering.

Abstract
AIMS The aim of this study was to compare the survivorship and radiographic outcomes at ten-year follow-up of three prospective consecutive series of patients each of which received a different design of cementless femoral components for total hip arthroplasty (THA). PATIENTS AND METHODS In Cohort 1, 91 consecutive patients (100 hips) underwent THA with a cementless porous-coated anatomic femoral stem (PCA) between October 1983 and January 1986. In Cohort 2, 86 consecutive patients (100 hips) underwent THA with an extensively porous-coated cementless femoral stem (Prodigy) between June 1994 and October 1997. In Cohort 3, 88 consecutive patients (100 hips) underwent THA with a proximally porous-coated triple-tapered cementless stem (Summit) between April 2002 and October 2003. All three groups underwent prospective clinical and radiographic evaluation. RESULTS Kaplan-Meier survivorship analysis of Cohort 1 was 91% (95% confidence interval (CI) 88 to 94) with an endpoint of revision for any reason and 97% (95% CI 95 to 99) with aseptic loosening as the endpoint. Survivorship of Cohort 2 was 88% (95% CI 79 to 97) for revision for any reason and 100% for aseptic loosening. Survivorship of Cohort 3 was 95% (95% CI 91 to 99) for revision for any reason and 100% with aseptic loosening as the endpoint. CONCLUSION With revision for aseptic loosening of the femoral component as the endpoint, the three femoral components with different design philosophies demonstrated excellent survivorship, ranging from 97% to 100% at ten years.

Abstract
Q fever (QF) is a worldwide zoonosis associated with outbreaks. Only a few nationwide studies regarding the surveillance and epidemiology of human QF have been reported. Although QF is endemic in Taiwan, a nationwide database investigation of the epidemiology and characteristics of QF and its associations with scrub typhus (ST), murine typhus (MT) and leptospirosis (LS) has never been reported. We analysed nationwide databases of suspected QF, ST, MT and LS cases from October 2007 to December 2014 obtained from the Centers for Disease Control, Taiwan. A total of 468 (4.2%) QF cases were identified among 11 109 suspected QF cases. QF cases were mainly distributed in the southern and Kaohsiung-Pingtung regions but rarely in the eastern region. Compared to non-QF cases, QF cases had significantly higher percentages of males (88.7 versus 66.2%) and high-risk occupations (farming, animal husbandry or veterinary medicine) (16.2 versus 10.5%). But the percentages of specific animal contact, including cattle (0.6 versus 0.8%) and goats (0.9 versus 1.0%), were low in both. The majority of suspected QF cases (89.4%) were simultaneously suspected with ST, MT or LS, and the combinations of suspected diseases differed between regions. The number of suspected QF cases from the eastern region decreased since 2009, which was not observed in other regions. A total of 1420 (12.8%) cases had confirmed diseases, including QF (453, 4.1%), QF+ST (7, 0.06%), QF+MT (4, 0.04%), QF+LS (4, 0.04%), MT (186, 1.7%), ST (545, 4.9%), ST+LS (11, 0.1%) and LS (210, 1.9%). Compared to cases of unknown disease, QF cases had larger percentages of high-risk occupations (16.2 versus 9.6%) but similar histories of animal contact (29.8 versus 25.1%). QF is an endemic disease in southern Taiwan. It is difficult to differentiate QF from ST, MT or LS only by high-risk occupations and history of animal contact, and co-infection of QF with these diseases should be considered.

Abstract
OBJECTIVE To investigate the treatment of surgical site infection(SSI) after spine surgery. METHODS Sixty-seven patients (aged 20-77 years with mean age of 51 years) with etiologically-confirmed surgical site infection after spine surgery in Peking University Third Hospital between July 2004 and December 2012 were retrospectively analyzed. There were 39 male and 28 female patients; 47 lumbar infections, 4 thoracic infections, 7 lower cervical infections and 8 upper cervical infections; 64 early infections and 3 delayed infections; 23 superficial infections and 44 deep infections; 47 monomicrobial infections and 20 polymicrobial infections. Ninety-six strains of bacteria were identified from the bacterial culture of 67 patients. Sixty strains were gram-positive pathogenic bacteria (62.5%), and the top three species were Staphylococcus aureus, S. epidermidis and Enterococcus faecalis. The remaining 36 strains were gram-negative pathogenic bacteria (37.5%), and the 3 species most predominant were Escherichia coli, Enterobacter cloacae, and Acinetobacter baumannii. All the patients with SSI were administered antibiotics. Debridement and irrigation-suction was performed if little symptomatic improvement was achieved in two-to-three days of antibiotics treatment, patients underwent 1-5 times of debridements (mean 1.5 times). RESULTS One patient was dead of MRSA septicemia, whom manifested as high fever, alalia and incision swelling when the infection occurred. The patient underwent polymicrobial of pulmonary infection and urinary tract infection during the period of hospitalization, and finally died of multiple organ failure. Sixty-six cases had wound healed, and they were followed up for 25-117 months (average 70 months), no recurrence of infection was found at last follow-up. Among the 65 cases of internal fixation, 56 cases reserved the implants, while implants were removed in other 9 cases for controlling infection. CONCLUSION Reasonable antibiotics and irrigation-suction are effective methods for managing surgical site infections after spine surgery and prevent removal of implants.

Abstract
Drought and salt stresses are the two major factors influencing the yield and quality of crops worldwide. Na(+)(K(+))/H(+) antiporters (NHXs) are ubiquitous membrane proteins that play important roles in maintaining the cellular pH and Na(+)(K(+)) homeostasis. The model plant Arabidopsis potentially encodes six NHX genes, namely AtNHX1 to 6. In the present study, AtNHX5, a comparatively less well-studied NHX, was cloned and transferred into a soybean variety, Dongnong-50, via Agrobacterium-mediated cotyledonary node transformation to assess its role in improving salt tolerance of the transgenic plants. The transgenic soybean plants were tolerant to the presence of 300 mM NaCl whereas the non-transgenic plants were not. Furthermore, after NaCl treatment, the transgenic plants had a higher content of free proline but lower content of malondialdehyde compared to the non-transgenic plants. Our results revealed that that AtNHX5 possibly functioned by efficiently transporting Na(+) and K(+) ions from the roots to the leaves. Overall, the results obtained in this study suggest that soybean salt tolerance could be improved through the over expression of Arabidopsis AtNHX5.

Abstract
This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9 GWth nuclear reactors with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls in the Daya Bay experiment. Using 217 days of data, 296 721 and 41 589 inverse β decay (IBD) candidates were detected in the near and far halls, respectively. The measured IBD yield is (1.55±0.04) ×10(-18) cm(2) GW(-1) day(-1) or (5.92±0.14) ×10(-43) cm(2) fission(-1). This flux measurement is consistent with previous short-baseline reactor antineutrino experiments and is 0.946±0.022 (0.991±0.023) relative to the flux predicted with the Huber-Mueller (ILL-Vogel) fissile antineutrino model. The measured IBD positron energy spectrum deviates from both spectral predictions by more than 2σ over the full energy range with a local significance of up to ∼4σ between 4-6 MeV. A reactor antineutrino spectrum of IBD reactions is extracted from the measured positron energy spectrum for model-independent predictions.

Abstract
OBJECTIVES The viscoelastic response of the midpalatal suture during maxillary expansion treatment has been sparsely studied. The aim of our study was to use viscoelastic models to investigate the effect of appliance mechanics on sutural tissue. MATERIALS AND METHODS Four creep-strain models were utilized in predicting the midpalatal suture's response to a constant-force application during expansion treatment. The functional forms included a three-term separable, three-term inseparable, two-term inseparable, and single-term arrangement. The functions were then transformed into subsequent stress-relaxation representations to predict suture response as a result of 0.25, 0.20, 0.15, and 0.10 mm displacements. Finally, the single-term creep-strain representation was altered to simulate treatment decaying force during treatment. A force that decays 30 and 10% of an initially applied 0.98 N was considered for decaying functions over a 6-week period, and compared to strain resulting from a constant-force application. RESULTS This analysis illustrated that the decay in suture strain closely followed decay in force and that the path of decay had minimal impact on overall results. Also, it was found that a single screw activation would likely not cause suture soft tissue failure, even for a 0.25 mm displacement, and that suture stress rapidly decayed within minutes of activation. CONCLUSION Results from this study support the notion of maintaining a low-magnitude constant traction on the suture during treatment to avoid soft tissue failure and promote tissue remodeling.

Abstract
We report a new measurement of electron antineutrino disappearance using the fully constructed Daya Bay Reactor Neutrino Experiment. The final two of eight antineutrino detectors were installed in the summer of 2012. Including the 404 days of data collected from October 2012 to November 2013 resulted in a total exposure of 6.9×10^{5} GW_{th} ton days, a 3.6 times increase over our previous results. Improvements in energy calibration limited variations between detectors to 0.2%. Removal of six ^{241}Am-^{13}C radioactive calibration sources reduced the background by a factor of 2 for the detectors in the experimental hall furthest from the reactors. Direct prediction of the antineutrino signal in the far detectors based on the measurements in the near detectors explicitly minimized the dependence of the measurement on models of reactor antineutrino emission. The uncertainties in our estimates of sin^{2}2θ_{13} and |Δm_{ee}^{2}| were halved as a result of these improvements. An analysis of the relative antineutrino rates and energy spectra between detectors gave sin^{2}2θ_{13}=0.084±0.005 and |Δm_{ee}^{2}|=(2.42±0.11)×10^{-3} eV^{2} in the three-neutrino framework.
