Abstract
Objective: To investigate the association of blood oxidative stress level with hypertriglyceridemia in the elderly aged 65 years and older in China. Methods: A total of 2 393 participants aged 65 years and older were recruited in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study, during 2017 to 2018. Information on demographics characteristic, life style and health status were collected by questionnaire and physical examination, and venous blood was collected to detect the levels of blood oxidative stress and hypertriglyceridemia. The linear or non-linear association between oxidative stress and hypertriglyceridemia was described by restrictive cubic splines (RCS) fitting multiple linear regression model. The generalized linear mixed effect model was conducted to assess the association between oxidative stress and hypertriglyceridemia. Results: A total of 2 393 participants, mean age was 84.6 years, the youngest was 65 and the oldest was 112, the male was 47.9%(1 145/2 393), the triglyceride level was (1.4±0.8) mmol/L. The hypertriglyceridemia detection rate was 9.99%(239/2 393). The results of multiple linear regression model with restrictive cubic spline fitting showed that MDA level was linear association with triglyceride level; SOD level was nonlinear association with triglyceride level. MDA level had significantly association with hypertriglyceridemia, and the corresponding OR value was 1.063 (95%CI: 1.046,1.081) with 1 nmol/ml increment of blood MDA; SOD level had significantly association with hypertriglyceridemia, and the corresponding OR value was 0.986(95%CI: 0.983,0.989) with 1 U/ml increment of blood SOD. Conclusion: Among the elderly aged 65 and older in 9 longevity areas in China, MDA and SOD levels were associated with the risk of hypertriglyceridemia.

Abstract
Restricted cubic spline Cox proportional hazard regression model analysis is an important method of epidemiological multivariate survival analysis. By comparing the typical Cox regression model and the restricted cubic spline Cox regression model, this study expounds the limitations of the typical Cox regression model, and explains the basic principles and implementation process of the restricted cubic spline Cox proportional hazard regression model. When the follow-up data does not meet the application conditions of the typical Cox regression model, this method can be used to realize the correlation analysis between continuous exposure and outcomes.

Abstract
OBJECTIVE In recent years, several circular RNAs (circRNAs) have been identified to play important roles in human cancers. However, the exact effects and molecular mechanisms of circRNAs in non-small cell lung cancer (NSCLC) progression are still unknown. In this study, we aimed to investigate the effect of circular hsa_circ_000984 on NSCLC. PATIENTS AND METHODS Quantitative real-time PCR was performed to detect the expression levels of hsa_circ_000984 in NSCLC tissues and cell lines. The associations between the expression of hsa_circ_000984 and clinicopathological parameters and patients' survival were analyzed. The cell growth was detected by CCK-8 assay and colony formation assay. Cell migration and invasion assays were used to study the changes in cell migration and invasion capacity. Western blot was performed to analyze the possible relationship between hsa_circ_000984 and the genes downstream of the Wnt/β-catenin pathway. RESULTS We found that hsa_circ_000984 was highly expressed in NSCLC tissues and cell lines and correlated with advanced TNM stage and lymph nodes metastasis. The clinical assays indicated that patients with high hsa_circ_000984 expression had shorter overall survival and disease-free survival. The functional investigations showed that the knockdown of hsa_circ_000984 suppressed NSCLC cells proliferation, migration, invasion, and EMT. Moreover, hsa_circ_000984 displayed its oncogenic roles by modulating the activation of Wnt/β-catenin pathway, which was demonstrated by measuring the expression levels of, β-catenin, c-myc, and cyclin D1. CONCLUSIONS Our findings may facilitate a better understanding of hsa_circ_000984, and it might be a potential prognostic biomarker and treatment target for NSCLC patients.

Abstract
Gastroesophageal reflux disease (GERD) is a common digestive disease with characteristics of a multitude of pathogenesis, a variety of clinical manifestations and a strong negative impact on physical and mental health of the patients. GERD is classified into non-erosive reflux disease and reflux esophagitis in terms of absence or presence of mucosal damage at endoscopic findings. Proton pump inhibitors (PPI) are widely used in the treatment of GERD, especially for patients with non-erosive reflux disease or mild reflux esophagitis. However, PPI do not affect pathophysiologic mechanisms of GERD or reduce the number of reflux events. When PPI fails to adequately control the symptoms of GERD as a result of gastroesophagel junction structural defects, the antireflux surgical procedures are indicated to create a mechanical barrier to reflux. The laparoscopic fundoplication remains the most commonly performed and is the current "gold-standard" anti-reflux procedure. The outcomes of the antireflux surgical procedures are superior to medical therapy for GERD in light of subjective symptoms, objective examinations, quality of life and patient satisfaction. As of now, enough attention has not been paid to the traditional surgical procedures of GERD in China. It is controversial about which is optimal among the three major types of procedures, selection should be tailored to classification, mechanism, age, mental status and esophageal motility. GERD is a chronic disease and either medical or surgical therapy may put the patient at different risk, therefore the patient's preferences should be considered adequately before choosing the treatment protocols.

Abstract
The polyvinyl formal (PVFM) biocarrier addition in a membrane bioreactor (MBR) was evaluated at high and low carbon/nitrogen (C/N) ratio of 20.0 and 6.7. Results indicated that static biocarrier addition could enrich nitrification and denitrification bacteria, dominating by Tauera, Amaricoccus and Nitrosospira at the genus level and slightly improved the total nitrogen removal even at a low C/N ratio. The bulk sludge characteristics (such as bigger particle size, lower SMP, lower SMP P/C) were also significantly changed in the hybrid MBR (HMBR), leading to a more sustainable membrane operation. The biocarrier addition also reduced the relative abundance of Sphingobacterials_unclassified, Ohtaekwangia and Rhodocyclaceae_unclassified at the genus level, indicating less membrane fouling in the HMBR. Consequently, HMBR with static PVFM addition could partially overcome the drawback of low C/N ratio for total nitrogen removal and membrane fouling control, providing a more resilient MBR to the undesirable environment such as low C/N ratio.

Abstract
Objective: To observe the effect of olfactory training on mice with olfactory dysfunction induced by 3-methylindole (3-MI). Methods: Thirty-one male BALB/c mice were randomly divided into 3 groups by random digits table: control group (group A, n=10), olfactory dysfunction group (group B, n=10) and olfactory dysfunction+olfactory training group (group C, n=11). Mice in group B and group C were intraperitoneally injected with 150 mg/kg 3-MI to induce olfactory dysfunction model, while mice in group A were intraperitoneally injected with corn oil of the same volume. From the first day after injection, mice in group C were treated with 4 kinds of odors by inhalation, while mice in group B were treated with distilled water by inhalation, with 2 times/d, 30 min/time/kind of odor, and continuous training for 28 d. Group A was not treated. Buried food pellet tests were conducted before injection and at 7, 14, 21 and 28 days after injection, respectively. The olfactory epithelium was harvested for observation of the number of olfactory marker protein (OMP) and the thickness of olfactory epithelium on the 28th day after injection. SPSS 23.0 software was used for statistical analysis. Results: Before injection, all mice in each group had no olfactory dysfunction. At the 7th, 14th, 21st and 28th days after injection, the food finding time of mice in group C was shorter than that in group B, and the difference was statistically significant ((175.88±100.50) s vs (266.73±46.83) s, (132.00±84.62) s vs (264.10±48.50) s, (103.57±77.43) s vs (197.43±69.78) s, (67.79±32.54) s vs (176.63±61.06) s, all P<0.05), but food finding time of mice in group B and C was longer than that in group A (the food finding time of group A at the 7th, 14th, 21st and 28th days after injection was (27.13±5.36) s, (25.83±7.28) s, (23.13±2.72) s, (26.63±7.60) s, respectively, all P<0.05). At the 28th day after olfactory training, the number of OMP positive cells in group B and C were fewer than that in group A, and the difference was statistically significant ((108.00±28.19)/HP vs (288.22±84.06)/HP, (199.33±58.55)/HP vs (288.22±84.06)/HP, all P<0.05). The number of OMP positive cells in group C were higher than that in group B (P<0.05). The number of OMP positive cells had negative correlation with food finding time (r=-0.886, P<0.01). As for the thickness of the olfactory epithelium, the thickness of group B was thinner than that in group A and C, and the difference was statistically significant ((59.57±31.27) μm vs (114.55±40.70)μm vs (90.54±37.72) μm, all P<0.05). Conclusion: Olfactory training can accelerate the recovery of olfactory function in 3-MI-induced olfactory impaired mice.

Abstract
Objective: To investigate the relationship of sleep duration and sleep quality with anxiety in the elderly aged 60 years and older in China. Methods: The elderly aged 60 years and older were selected from the China Short-term Health Effects of Air Pollution Study conducted between July 18, 2017 and February 7, 2018. Multivariate logistic regression models were used to analyze the association of sleep duration and sleep quality with anxiety. Results: A total of 3 897 elderly aged 60 years and older were included in the study. The age of the elderly was (73.4±8.0) years old. Among the elderly surveyed, 6.5% were defined with anxiety, and 18.7% reported poor sleep quality. Multivariate logistic regression models showed shorter sleep duration was the risk factor for anxiety in the elderly that after adjusting for factors such as general demographics, socioeconomic factors, lifestyle, health status, social support and ambient fine particulates exposure. Compared with the elderly with 7 hours of sleep duration daily, the OR (95%CI) of anxiety for those with sleep duration ≤ 6 hours was 2.09 (1.49-2.93). Compared with those with good sleep quality, the OR (95%CI) of anxiety for those with poor sleep quality was 5.12 (3.88-6.77). We also found statistically significant correlations of the scores of subscales of Pittsburgh sleep quality index with anxiety, in which the effects of sleep disturbance, subjective sleep quality and daytime dysfunction scores were most obvious, the ORs (95%CI) were 4.63 (3.55-6.04), 2.75 (2.33-3.23) and 2.50 (2.19-2.86), respectively. Subgroup analysis showed that the association of sleep duration and sleep quality with anxiety was more obvious in males and in those aged <80 years. Conclusion: Shorter sleep duration and poor sleep quality are associated with anxiety in the elderly in China.

Abstract
Objective: To establish a prediction model for 6-year incidence risk of chronic kidney disease (CKD) in the elderly aged 65 years and older in China. Methods: In this prospective cohort study, we used the data of 3 742 participants collected during 2008/2009-2014 and during 2012-2017/2018 from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey. Two follow up surveys for renal function were successfully conducted for 1 055 participants without CKD in baseline survey. Lasso method was used for the selection of risk factors. The risk prediction model of CKD was established by using Cox proportional hazards regression models and visualized through nomogram tool. Bootstrap method (1 000 resample) was used for internal validation, and the performance of the model was assessed by C-index and calibration curve. Results: The mean age of participants was (80.8±11.4) years. In 4 797 person years of follow up, CKD was found in 262 participants (24.8%). Age, BMI, sex, education level, marital status, having retirement pension or insurance, hypertension prevalence, blood uric acid, blood urea nitrogen and total cholesterol levels and estimated glomerular filtration rate in baseline survey were used in the model to predict the 6-year incidence risk of CKD in the elderly. The corrected C-index was 0.766, the calibration curve showed good consistence between predicted probability and observed probability in high risk group, but relatively poor consistence in low risk group. Conclusion: The incidence risk prediction model of CKD established in this study has a good performance, and the nomogram can be used as visualization tool to predict the 6-year risk of CKD in the elderly aged 65 years and older in China.

Abstract
Objective: To investigate the association between estimated glomerular filtration rate (eGFR) and all-cause mortality in the elderly aged 65 years and older in longevity areas in China. Methods: Data used in this study were obtained from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey, 1 802 elderly adults were collected in the study during 2012-2017/2018. In this study, the elderly were classified into 4 groups, moderate-to-severe group [<45 ml·min(-1)·(1.73 m(2))(-1)], mild-to-moderate group [45- ml·min(-1)·(1.73 m(2))(-1)], mild group [60- ml·min(-1)·(1.73 m(2))(-1)] and normal group [≥90 ml·min(-1)·(1.73 m(2))(-1)] according to their eGFR levels. Results: After 6 years of follow-up, 852 participants died, with a mortality rate of 47.3%. Multivariate Cox regression analysis showed that the levels of eGFR were negatively correlated with all-cause mortality risk in the elderly (the HR of elderly was 0.993 and the 95%CI was 0.989-0.997 for every unit of eGFR increased, P=0.001), while compared with the group with normal eGFR, the HRs (95%CI) of the elderly in the moderate-to-severe group, mild-to-moderate group, and mild group were 1.690 (1.224-2.332, P=0.001), 1.312 (0.978-1.758, P=0.070), 1.349 (1.047-1.737, P=0.020) respectively [trend test P<0.001]. Conclusion: The decrease in eGFR was associated with higher mortality risk among the elderly in longevity areas in China.

Abstract
Objective: To analyze influencing factors for depressive symptoms in the elderly aged 65 years and older in 8 longevity areas in China. Methods: We recruited 2 180 participants aged 65 years and older in 8 longevity areas from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey in 2017. Multivariate logistic regression analysis was performed to evaluate the relationships of socio-demographic characteristics, behavioral lifestyle, chronic disease prevalence, functional status, family and social support with depressive symptoms in the elderly. Results: The detection rate of depression symptoms was 15.0% in the elderly aged 65 years and older in 8 longevity areas of China, and the detection rate of depression symptoms was 11.5% in men and 18.5% in women. Multivariate logistic regression analysis results showed that the detection rate of depressive symptoms was lower in the elderly who had regular physical exercises (OR=0.44, 95%CI: 0.26-0.74), frequent fish intakes (OR=0.57, 95%CI: 0.39-0.83), recreational activities (OR=0.65, 95%CI: 0.44-0.96), social activities (OR=0.28, 95%CI: 0.11-0.73) and community services (OR=0.68, 95%CI: 0.50-0.93). The elderly who were lack of sleep (OR=2.04, 95%CI: 1.49-2.80), had visual impairment (OR=1.54, 95%CI: 1.08-2.18), had gastrointestinal ulcer (OR=2.97, 95%CI: 1.53-5.77), had arthritis (OR=2.63, 95%CI: 1.61-4.32), had higher family expenditure than income (OR=1.80, 95%CI: 1.17-2.78) and were in poor economic condition (OR=4.58, 95%CI: 2.48-8.47) had higher detection rate of depressive symptoms. Conclusion: The status of doing physical exercise, fish intake in diet, social activity participation, sleep quality or vision, and the prevalence of gastrointestinal ulcers and arthritis were associated with the detection rate of depressive symptoms in the elderly.

Abstract
Objective: To study influencing factors which cause the endometrial diseases in patients with breast cancer after operation. Methods: A retrospective study was performed on 212 breast cancer post-operation patients with endometrial diseases between June 2006 and January 2018 in Women's Hospital School of Medicine Zhejiang University to analyse the factors which influenced the endometrial diseases. Results: The abnormal uterine bleeding and endometrial thickness were related to the severity of endometrial disease in patients with breast cancer, and they were independent risk factors for breast cancer patients to have endometrial cancer (P<0.05) . When the diagnostic cut off value of endometrial thickness was ≥0.49 cm, the sensitivity and specificity to endometrial cancer were 78% and 25%, respectively. The average endometrial thickness was (0.56±0.39) cm in patients who were treated by selective estrogen receptor modulator (SERM) after gynecological surgery, which was significantly thicker than that of aromatase inhibitor (AI) group [ (0.33±0.23) cm] and no treatment group [ (0.44±0.28) cm, P<0.05]. The endometrial disease recurrent rate and reoperation rate in SERM group were (26.2%, 14.3%) slightly higher than that of AI group (9.5%, 4.8%) and no treatment group (21.6%, 4.9%), but there were not significant differences (all P>0.05). Conclusions: The clinical symptom of abnormal uterine bleeding and thickening endometrium are risk factors for breast cancer patients to have endometrial cancer. The endometrial thickness has high predictive value for breast cancer patients to diagnose endometrial cancer. The SERM treatment increases the endometrial thickness, recurrent rate and reoperation rate in post-operation patients.

Abstract
OBJECTIVE In liver transplantation, long-time portal vein blocking causes the occurrence of ischemic liver injury. Dexmedetomidine, a widely admired anesthetic, has been reported as a protective agent on organs under ischemic condition. The objective of this study was to reveal the role and underlying mechanism of dexmedetomidine in ischemic liver injury. MATERIALS AND METHODS L-02 cells were treated with dexmedetomidine during 6 h of oxygen-glucose deprivation (OGD) exposure. The expression of microRNA-711 (miR-711) in cell was overexpressed by miRNA transfection. Then, the following parameters were observed: cell viability, apoptosis, the expression of apoptosis-related proteins, and the expression and the release of Interleukin 1 beta (IL-1β) and Tumor necrosis factor alpha (TNF-α). RESULTS Apoptosis and inflammation were induced following OGD exposure in L-02 cells, as cell viability was impaired, apoptotic cell rate was increased, caspase-3, and caspase-9 was cleaved, and the expression and release of TNF-α and IL-1β were increased. Dexmedetomidine attenuated OGD-induced apoptosis and inflammation, and dexmedetomidine down-regulated the expression of miR-711. Also, dexmedetomidine blocked the activation of p38 mitogen-activated protein kinase (p38MAPK) and Janus kinase (JAK)/signal transducer and activator of transcription protein (STAT) signaling upon OGD. Moreover, when miR-711 was overexpressed, dexmedetomidine did not protect L-02 cells against OGD, and did not block p38MAPK and JAK/STAT signaling pathways. CONCLUSIONS Dexmedetomidine ameliorated OGD-induced cell apoptosis and inflammation in L-02 cells, exerting protective activities in ischemic liver injury. The anti-OGD effects of dexmedetomidine might be realized by down-regulation of miR-711 and suppression of p38MAPK and JAK/STAT signaling pathways.

Abstract
Objective: To investigate the relationship of plasma albumin and hypersensitive C-reactive protein (Hs-CRP) with 5-year all-cause mortality among Chinese older adults aged 65 and older. Method: Data was collected in 8 longevity areas of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) study conducted by Chinese Center for Disease Control and Prevention and Peking University at baseline survey in 2012 and 2014, the participants enrolled in 2012 was followed-up in 2014 and 2017, the participants enrolled in 2014 was followed-up in 2017 only. Finally, 3 118 older adults aged 65 and older with complete information on albumin, Hs-CRP and body mass index (BMI) were included in this study. Plasma samples of older adults were collected for the detection of albumin and Hs-CRP at baseline survey. Survival status and follow-up time was recorded for all participants. All older adults were divided into 4 groups according to the levels of plasma albumin and Hs-CRP, and Cox proportional hazard models were constructed to assess their influence on the risk of all-cause mortality. Results: Among 3 118 older adults included, the prevalence of hypoalbuminemia was 10.1% (316/3 118), and was 22.8% (711/3 118) for elevated Hs-CRP. During 10 132 person-years of follow-up, 1 212 participants died. Participants with hypoalbuminemia had increased risk of all-cause mortality, with an hazard ratio (HR) and 95% confidential interval (CI) of 1.18 (1.01-1.38), compared to participants with normal plasma albuminemia; participants with elevated Hs-CRP had increased risk of all-cause mortality, with an HR (95%CI) of 1.18 (1.04-1.35), compared to participants with normal plasma Hs-CRP. Participants with normal plasma albumin and elevated Hs-CRP, with hypoalbuminemia and normal Hs-CRP, with hypoalbuminemia and elevated Hs-CRP also had increased risk of all-cause mortality when compared to those with normal plasma albumin and normal Hs-CRP, the HR (95%CI) were 1.16 (1.01-1.34), 1.11 (0.91-1.37) and 1.43 (1.11-1.83), respectively. Conclusion: Hypoalbuminemia and elevated Hs-CRP were responsible for increased risk of 5-year all-cause mortality among Chinese older adults from 8 longevity areas.

Abstract
Parapharyngeal space refers to the potential space under skull base between masticatory muscles and pharyngeal muscles, ranging from skull base at the top to hyoid bone at the bottom. The outer lateral wall consists of medial pterygoid muscle, deep parotid lobe and lower jawbone, lateral pharyngeal wall, medial pterygoid, deep lobe of parotid gland and mandible constitute the lateral wall, lateral pharyngeal wall forms medial wall, and prevertebral fascia constitutes the posterior wall, generally forming an inverted pyramid lacuna. Parapharyngeal space is divided into prestyloid space and poststyloid space by stylopharygeal fascia. Prestyloid space is relatively small and contains levator veli palatinetensor veli palatine, branches of maxillary artery, mandibular nerve and its branches. Poststyloid space is relatively large. It includes internal jugular vein, internal carotid artery, posterior cranial nerves, etc. Poststyloid space tumors are relatively rare. In this report, a case of ganglioneuroma wrapping right internal carotid artery is described, which is resected through oral approach.

Abstract
Objective: To compare the short-term outcomes of CO₂ laser and conventional laryngeal microsurgery for vocal cord cyst. Method: Patients with vocal cord cyst were divided randomly into two groups. One group was treated with CO₂ laser (laser group) and the other underwent Micro-flap surgery(Micro-flap group). For the objective assessment, Amulti-dimensional voice program module for voice spectrum analysis was used. Result: In the laser group, there were no significant differences between the preoperative and 1 week postoperative parameters of Jitter, Shimmer and HNR(P>0.05). However,the parameters of G and VHI-10 were significantly different between the laser group and Micro-flap group(P<0.05). The objective data of the laser group pre-and post-surgery showed that the voice recovery of the laser group was significantly better than that of the Micro-flap group after 1 to 3 months of follow-up(P<0.05). But no significant differences of the parameters of G and VHI-10 was noted between the laser group and Micro-flap group(P>0.05). Conclusion: CO₂ laser laryngeal microsurgery for vocal cord cyst can significantly improve pronunciation quality.

Abstract
Internal ribosomal entry site (IRES) functions as a cis-acting RNA element, which drives an alternative and cap-independent translation initiation pathway. Currently, there are few studies on effects of nucleotide usages at key nucleotide positions +4 and -3 flanking start codon mediated by IRES of hepatitis C virus (HCV). Herein, we focus on the effect of nucleotide usages at -3 and +4 positions mediated by HCV IRES. The nucleotide contexts flanking AUG start codon employed by HCV IRES is firstly analyzed. We found that each position in the six nucleotide positions (-4 to +6) flanking start codon of HCV has a strong tendency to select the specific nucleotide. A set of bicistronic expression vectors containing CAT gene, HCV IRES and EGFP gene were constructed, including 16 different nucleotide combinations at position -3 and +4. Each set, in which nucleotide at the -3 and +4 position has been changed into different nucleotides, included 16 types of bicistronic expression vectors. It was found that the purine nucleotide at the position -3 or +4 obviously impacts on HCV IRES-related expression, and IRES-driven translation is potentially influenced by the Kozak rule. Our results suggest that optimization of nucleotides at positions -3 and +4 is a convenient and efficient way to enhance the level of IRES-mediated translation. Keywords: Cap-independent translation; internal ribosomal entry site; hepatitis C virus; bicistronic expression vector; translation efficiency.

Abstract
Objective: To establish comprehensive laboratory reference intervals for Chinese children. Methods: This was a cross-sectional multicenter study. From June 2013 to December 2014, eligible healthy children aged from 6-month to 17-year were enrolled from 20 medical centers with informed consent. They were assessed by physical examination, questionnaire survey and abdominal ultrasound for eligibility. Fasting blood samples were collected and delivered to central laboratory. Measurements of 15 clinical laboratory parameters were performed, including estradiol (E2), testosterone(T), luteinizing hormone(LH), follicle-stimulating hormone(FSH), alanine transaminase(ALT), serum creatinine(Scr), cystatin C, immunoglobulin A(IgA), immunoglobulin G(IgG), immunoglobulin M(IgM), complement (C3, C4), alkaline phosphatase(ALP), uric acid(UA) and creatine kinase(CK). Reference intervals were established according to central 95% confidence intervals for reference population, stratified by age and sex. Results: In total, 2 259 children were enrolled. Finally, 1 648 children were eligible for this study, including 830 boys and 818 girls, at a mean age of 7.4 years. Age- and sex- specific reference intervals have been established for the parameters. Reference intervals of sex hormones increased gradually with age. Concentrations of ALT, cystatin C, ALP and CK were higher in children under 2 years old. Serum levels of sex hormones, creatinine, immunoglobin, CK, ALP and urea increased rapidly in adolescence, with significant sex difference. In addition, reference intervals were variable depending on assay methods. Concentrations of ALT detected by reagents with pyridoxal 5'-phosphate(PLP) were higher than those detected by reagents without PLP. Compared with enzymatic method, Jaffe assay always got higher results of serum creatinine, especially in children younger than 9 years old. Conclusion: This study established age- and sex- specific reference intervals, for 15 clinical laboratory parameters based on defined healthy children.

Abstract
BACKGROUND Semenogelin 1 (SEMG1) is an important secretory protein in spermatozoa involved in the formation of a gel matrix encasing ejaculated spermatozoa. Previous studies show that the SEMG1 gene is highly expressed in spermatozoa from patients with asthenozoospermia (AZS); however, the underlying molecular mechanisms are not yet clear. OBJECTIVES To study the molecular mechanism of high expression of SEMG1 gene and its potential roles in AZS. MATERIALS AND METHODS Western blot and real-time PCR were used to detect the expression levels of SEMG1 protein and mRNA in the ejaculated spermatozoa from normozoospermic males and AZS patients. Bioinformatics analysis was used to predict miRNAs targeting for SEMG1 3'-untranslated region detection of the expression levels of all the candidate miRNAs in ejaculatory spermatozoa in AZS patients or normozoospermic volunteers. Luciferase reporter assays were performed to confirm it can directly bind to SEMG1. Correlation of miR-525-3p and SEMG1 mRNA expression with clinical sperm parameters were also analyzed. Finally, we conducted a follow-up study of reproductive history about all the subjects. RESULTS SEMG1 mRNA and protein level were significantly higher in AZS patients compared to that in normozoospermic volunteers (p < 0.001). Subsequently, microRNA-525-3p (miR-525-3p) which was predicted as a candidate regulator of SEMG1 was found lower expressed in ejaculatory spermatozoa in AZS patients (p = 0.0074). Luciferase experiment revealed that microRNA-525-3p could directly target SEMG1 3'-untranslated region and suppress its expression. Importantly, our retrospective follow-up study showed that both low miR-525-3p expression and high SEMG1 expression level was significantly associated with low progressive sperm motility, abnormal sperm morphology, and infertility. DISCUSSION AND CONCLUSION The elevated expression of SEMG1 and reduced expression of miR-525-3p are associated with AZS and male infertility. Our study provides a potential therapeutic target for the treatment of male infertility or for male contraception.

Abstract
OBJECTIVE To explore the role of γδT cells against bladder cancer and to detect the expression of stress proteins MICA/B recognized by γδT cells in bladder cancer. METHODS γδT cells from peripheral blood drawn from 6 bladder cancer patients with pamidronate stimulating were expanded. Flow cytometry was used to detect the purity and expansion folds of γδT cells, and the expression of CD107a on γδT cells after PMA/ionomycin stimulated. The cytotoxicity assay was carried out to test the cytotoxicity of γδT cells against human bladder cancer cell lines. The expression of MICA/B on bladder cancer cell lines and in bladder cancer tissues were detected through flow cytometry and immunohistochemistry respectively. RESULTS γδT cells from peripheral blood drawn from 6 bladder cancer patients were successfully expanded. The purity was 75%-94% and the expansion folds were 109-371 times. After being stimulated by PMA/ionomycin, the proportion of CD107a+ γδT cells increased significantly, reaching 40%-82%. γδT cells from the 6 bladder cancer patients showed obvious cytotoxic effects on 3 human bladder cancer cell lines which was enhanced as the effector: the target ratio increased. MICA/B were detected both in 3 bladder cancer cell lines and in 26 bladder cancer tissues. The staining score of MICA/B in invasive bladder cancer was slightly higher than that in non-invasive bladder cancer, and in advanced bladder cancer was higher than that in low grade bladder cancer, but the statistical analysis showed that the staining score of MICA/B was no significant correlation between the tissue and the tumor stages and grades. CONCLUSION γδT cells from the peripheral blood of the bladder cancer patients could be successfully expanded in vitro, and showed significant anti-bladder cancer effect. MICA/B were detected both in bladder cancer cell lines and in bladder cancer tissues. The statistical analysis showed that there was no significant correlation between the staining scores of MICA/B in the tissue and the tumor stages and grades.

Abstract
Objective: To analyze the genetic characterization of glycoprotein M(gM.),glycoprotein L(gL) of varicella zoster virus. Methods: According to the program of "Ministry of Science and Technology of China" , Based on the 12 suspected VZV patients monitored in Beijing (1 case), Shanghai (5 cases), Jilin (2 cases), Qinghai (1 case), Guangdong (2 case) and Sichuan (case) in 2007-2015. A total of 12 Vesicle fluid and throat swab samples were collected. Positive samples were identified by Agarose gel electrophoresis and two glycoprotein genes were amplified by polymerase chain reaction (PCR). Nucleotide sequences were determined and analyzed by PCR amplification of VZV positive specimens V-OKA-BK of the domestic varicella attenuated live vaccine and the Varilrix-1 of the imported attenuated live vaccine. Nucleotide sequences of VZV positive specimens, vaccine strains (V-OKA-BK, varilrix-1) and GenBank foreign wild strains (41 strains), parent strains (P-oka), vaccine strains (V-oka, Varilrix, Varivax) were compared using BioEdit and MEGA 5.0. Results: 12 specimens were VZV positive. Compared with the vaccine strains and the parent strains, the GM gene of 1 positive specimen had radical mutation at 86686 sites, which resulted in amino acid mutation, 5 positive specimens had base mutation at 87844 sites, and 30 strains of foreign wild strains had the same variation at 87 844 sites. 1 positive specimens of gL gene in 101245 sites had base mutation, and led to amino acid mutation, 6 positive specimens at 101624, 101625, 101626 sites had base of loss and the foreign wild strains in these 3 sites had the same variation. Compared with the vaccine strains, the nucleotide and amino acid homology of gM of 12 VZV positive specimens were 99.2%-100% and 98.2%-100%, respectively, and gL of those were 99.3%-100% and 98.6%-100%, respectively. Compared with 41 strains of foreign wild strains, homology of gM's nucleotides and amino acid were 99.3%-100% and 98.5%-100%, respectively; 99.1%-100% and 98.6%-100% for gL. The results of phylogenetic analysis showed that 7 VZV positive samples were on the same branch with 4 vaccine strains and p-oka strain. Based on gL, 12 VZV positive samples were on the same branch as the vaccine strains and p-oka strain. Conclusion: This study demonstrates that the genes of gM, gL are highly conserved and remain stable immunogen, which may be involved in the attenuation of VZV and need to be further researched.

Abstract
Objective: To study the willingness and influence factors related to "centralized slaughtering, fresh poultry listing and marketing" strategy, among the household chefs, and provide reference for government to adjust and optimize the strategy on avian influenza prevention. Methods: According to the geographical characteristics and regional functions, 6 'monitoring stations' were selected from 12 residential districts of Guangzhou, respectively. Another 21 meat markets which selling live poultry, were selected in each station and 5 household chefs of each market were invited to attend a face to face interview. Basic information, personal cognitive, willingness and influencing factors to the policy were under study. Univariate and multivariate logistic regression methods were used. Results: A total of 664 household chefs underwent the survey and results showed that the rate of support to the "centralized slaughtering, fresh poultry listing and marketing" strategy was 44.6% (296/664). Results from the multi-factor logistic regression showed that those household chefs who were males (OR=1.618, 95% CI: 1.156-2.264, P=0.005), having received higher education (OR=1.814, 95% CI: 1.296-2.539, P=0.001), or believing that the existence of live poultry stalls was related to the transmission of avian influenza (OR=1.918, 95% CI: 1.341-2.743, P<0.001) were factors at higher risk. These household chefs also intended to avoid the use of live poultry stalls (OR=1.666, 95%CI: 1.203-2.309, P=0.002) and accept the "centralized slaughtering, fresh poultry listing and marketing" strategy. Conclusion: Detailed study on this subject and, setting up pilot project in some areas as well as prioritizing the education programs for household chefs seemed helpful to the implementation of the 'freezing-fresh poultry' policy.

Abstract
OBJECTIVE To investigate the clinical usefulness of echocardiography in the diagnosis of infracardiac total anomalous pulmonary venous connection (ITAPVC) in neonates and infants. METHODS Retrospective analysis on 8 patients with ITAPVC was performed using echocardiography between April 2006 and December 2016. There were 4 boys and 4 girls with a mean age of 79.8 days (ranging from 15 to 195 days). A combined scanning via parasternal, subcostal and apical acoustic windows had been employed to diagnose ITAPVC and to trace the course and site of the anomalous pulmonary venous drainage, and to confirm the direction of the inter-atrial shunt and enlargement of right atrium and right ventricle. RESULTS Of the 8 patients who received echocardiography, ITAPVC was diagnosed in 7 patients. Mis-diagnosis by echocardiography was encountered in one patient. The diagnosis by echocardiography was compatible with the operative findings in 5 patients receiving surgery and with the results of multislice computed tomography in 6 patients. The diagnostic accuracy rate of ITAPVC was 87.5%. The indirect signs obtained from echocardiogram was coexistence of a small malformed, triangle-shaped left atrium and right to left shunting at atrial level with dilatation and tortuousness of portal vein or hepatic vein and abundant blood flow in liver. The direct signs was total pulmonary veins unconnected with left atrium, whose confluence joining into vertical vein drained right-inferiorly to portal vein or hepatic vein through diaphragm. Three parallel vessels including vertical vein, abdominal aorta and inferior vena cava arranged anteriorly, left-posteriorly and right-posteriorly with the opposite flow directions of inferior vena cava and the other two were found on sub-costal view. Sites of the drainage to the infra-diaphragm veins located portal vein in 8 patients. Stenosis of site of vertical vein connecting to portal vein or hepatic veins occurred in 3 patients. CONCLUSION Echocardiography has significant value in the diagnosis of pediatric ITAPVC and is capable of providing important structural and hemodynamic information for preoperative assessment of surgery. With multiple windows and multiple sections, ITAPVC could be diagnosed accurately by echocardiography. However, it is necessary to differentiate ITAPVC with intrahepatic portosystemic venous shunts or hepatic arteriovenous fistula.
