Abstract
BACKGROUND Renal fibrosis is considered an irreversible pathological process and the ultimate common pathway for the development of all types of chronic kidney diseases and renal failure. Diosmin is a natural flavonoid glycoside that has antioxidant, anti-inflammatory, and antifibrotic activities. However, whether Diosmin protects kidneys by inhibiting renal fibrosis is unknown. We aimed to investigate the role of Diosmin in renal interstitial fibrosis and to explore the underlying mechanisms. METHODS The UUO mouse model was established and gavaged with Diosmin (50 mg/kg·d and 100 mg/kg·d) for 14 days. HE staining, Masson staining, immunohistochemistry, western blotting and PCR were used to assess renal tissue injury and fibrosis. Elisa kits were used to detect the expression levels of IL-1β, IL-6, and TNF-α and the activity of SIRT3 in renal tissues. In addition, enrichment maps of RNA sequencing analyzed changes in signaling pathways. In vitro, human renal tubular epithelial cells (HK-2) were stimulated with TGF-β1 and then treated with diosmin (75 μM). The protein and mRNA expression levels of SIRT3 were detected in the cells. In addition, 3-TYP (selective inhibitor of SIRT3) and SIRT3 small interfering RNA (siRNA) were used to reduce SIRT3 levels in HK-2. RESULTS Diosmin attenuated UUO-induced renal fibrosis and TGF-β1-induced HK-2 fibrosis. In addition, Diosmin reduced IL-1β, IL-6, and TNF-α levels in kidney tissues and supernatants of HK-2 medium. Interestingly, Diosmin administration increased the enzymatic activity of SIRT3 in UUO kidneys. In addition, Diosmin significantly increased mRNA and protein expression of SIRT3 in vitro and in vivo. Inhibition of SIRT3 expression using 3-TYP or SIRT3 siRNA abolished the anti-inflammatory effects of diosmin in HK-2 cells. Enrichment map analysis by RNA sequencing indicates that the nuclear factor-kappa B (NF-κB) signaling pathway was inhibited in the Diosmin intervention group. Furthermore, we found that TGF-β1 increased the nuclear expression of nuclear NF-κB p65 but had little significant effect on the total intracellular expression of NF-κB p65. Additionally, Diosmin reduced TGF-β1-caused NF-κB p65 nuclear translocation. Knockdown of SIRT3 expression by SIRT3 siRNA increased the nuclear expression of NF-κB p65 and abolished the inhibition effect of Diosmin in NF-κB p65 expression. CONCLUSIONS Diosmin reduces renal inflammation and fibrosis, which is contributed by inhibiting nuclear translocation of NF-κB P65 through activating SIRT3.

Abstract
Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.

Abstract
The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.

Abstract
Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

Abstract
Chronic kidney disease (CKD), a global disease burden related to high rates of incidence and mortality, manifests as progressive and irretrievable nephron loss and decreased kidney regeneration capacity. Emerging studies have suggested that exposure to air pollution is closely relevant to increased risk of CKD, CKD progression and end-stage kidney disease (ESKD). Inhaled airborne particles may cause vascular injury, intraglomerular hypertension, or glomerulosclerosis through non-hemodynamic and hemodynamic factors with multiple complex interactions. The mechanisms linking air pollutants exposure to CKD include elevated blood pressure, worsening oxidative stress and inflammatory response, DNA damage and abnormal metabolic changes to aggravate kidney damage. In the present review, we will discuss the epidemiologic observations linking air pollutants exposure to the incidence and progression of CKD. Then, we elaborate the potential roles of several air pollutants including particulate matter and gaseous co-pollutants, environmental tobacco smoke, and gaseous heavy metals in its pathogenesis. Finally, this review outlines the latent effect of air pollution in ESKD patients undergoing dialysis or renal transplant, kidney cancer and other kidney diseases. The information obtained may be beneficial for further elucidating the pathogenesis of CKD and making proper preventive strategies for this disease.

Abstract
The present study aimed to investigate the levels of IL-36α and its association with disease activity in patients with systemic lupus erythematosus (SLE). A total of 60 patients with SLE and 29 healthy controls were enrolled in the present study. Disease activity was evaluated using the SLE disease activity index (SLEDAI). The serum levels of IL-36α, IL-36 receptor antagonist (IL-36Ra) and IL-17 were assessed using ELISA. The levels of IL-36α in patients with SLE were significantly higher compared with those of healthy controls. There was a significant increase in IL-36α in the active SLE group (SLEDAI score ≥5) compared with that of the healthy controls (P<0.001). The serum IL-36α levels were higher in patients with active SLE than in patients with quiescent disease (P=0.012). IL-36Ra was downregulated in patients with SLE (P=0.007). The serum IL-17 levels were elevated in patients with SLE (P=0.036), and a positive correlation was observed between the IL-36α and IL-17 levels (r=0.453, P=0.003). The serum IL-36α levels were associated with SLEDAI (r=0.374, P=0.003), proteinuria (r=0.329, P=0.010) and complement 3 (r=-0.336, P=0.009). Patients who were receiving glucocorticoid treatment had lower IL-36α levels than those who were not receiving glucocorticoid treatment (P=0.003). Patients with lupus nephritis had higher serum IL-36α levels compared with those found in patients without lupus nephritis (P=0.037). The serum IL-36α concentration was elevated in patients with SLE, and was correlated with disease activity and IL-17 levels. The aberrant serum IL-36α levels observed in the present study and its clinical association with SLE suggest the important role of IL-36α in onset and progression of SLE. In addition, the association of IL-36α with IL-17 level indicates its involvement in the regulation of T helper 17 cytokines.

Abstract
Objective: To identify the threshold of a health warning system based on the association of apparent temperature and years of life lost (YLL). Methods: Daily mortality records and meteorological data were collected from 364 Chinese counties for 2006-2017. Distributed lag nonlinear model and multivariate Meta-analyses were applied to estimate the association between the apparent temperature and YLL rate. A regression tree model was employed to estimate the warning thresholds of the apparent temperature. Stratified analyses were further conducted by age and cause of death. Results: The daily YLL rate was 23.6/105. The mean daily apparent temperature was 15.7 ℃. U-shaped nonlinear associations were observed between apparent temperature and YLL rate. The actual temperature-caused YLL rate for the elderly was higher than the young population. The daily excess deaths rate increased with the higher effect levels. Conclusions: Regression tree model was employed to define the warning threshold for meteorological health risk. The present study provides theoretical support for the weather-related health warning system.

Abstract
Our team utilized qRT-PCR for prospecting miR-32 expression level in primary lung carcinoma tissues and cell lines, as well as Kaplan–Meier method for dissecting the relation of miR-32 expression with the prognosis of lung carcinoma. We transfected lung cancer A549 cells with
miR-32 mimic/inhibitor and mimic/inhibitor NC, and appraised the influences of miR-32 on the phenotype changes of lung carcinoma cells via MTT assay, wound healing assay and cell apoptosis assay, separately. Then the target gene of miR-32 was predicted via bioinformatics. Finally, Western
blotting was adopted for analyzing the impact of alteration of miR-32 expression on the PI3K/Akt axis in A549 cells. In lung carcinoma tissues as well as cells, miR-32 expression is down-regulated, and miR-32 partakes in the progress of lung carcinoma via PI3K/Akt pathway.

Abstract
Objective: To study the association between apparent temperature (AT) and the incidence of hand,foot, and mouth disease (HFMD) and its spatial heterogeneity in 46 cities in Guangdong, Anhui and Jilin provinces, and provide scientific evidence for the early warning of HFMD. Methods: The data of HFMD incidence and meteorological factors from 2009 to 2018 in Guangdong province, 2009 to 2015 in Anhui province, and 2013 to 2018 in Jilin province were collected. Distributed lag non-linear models were constructed to investigate the association between AT and the incidence of HFMD in 46 cities from three provinces in China. Meta-analysis was used to pool the city-specific estimates, and Meta-regression was applied to analyze the factors that may cause spatial heterogeneity. Results: The relationship between daily AT and the incidence of HFMD in 46 cities appeared nonlinear. The association in Guangdong was similar to that in Jilin, and the risk of HFMD increased with the increase of AT. While the risk of HFMD in Anhui first increased with the increase of AT, and peaked at 18.1 ℃ and then went down. AT on different levels showed different lag impacts and the higher AT showed greater and longer lag impact. The spatial heterogeneity of associations may have been caused by latitude, longitude, average temperature, and average sunshine hours. Conclusions: AT is a comprehensive index to evaluate the association between temperature, relative humidity and wind speed and the incidence of HFMD. Higher AT may increase the risk of HFMD. The AT and HFMD relationship across spatial heterogeneity varies depending on geographic location and meteorological conditions.

Abstract
Objective To discuss the effects of polybrominated diphenyl ethers (PBDEs) exposure in e-waste dismantling region on the human body and provide data support for the identification of environmental health damage to residents in the e-waste dismantling region. Methods Adults in an e-waste dismantling region (exposed group, 54 participants) and a control region (control group, 58 participants) were selected, questionnaires were carried out and blood and urine samples were collected. Blood PBDEs, blood lipids, blood routine, blood lead, urine cadmium, urine chromium and urine nickel were detected. T-test was utilized to compare the differences of PBDEs between the two groups. Multivariate analysis were utilized to compare the differences between the two groups in blood routine indexes. Linear regression was used to analyze the relationship between PBDEs and blood routine. Results Exposure levels of PBDEs were significantly higher in the exposed group (240.00 ng/g, adjusted mass fraction of blood lipids, thereafter) than in the control group (93.00 ng/g, P<0.05). There was no statistical significance in the differences in most blood routine indexes of the two groups ( P>0.05), and their reference values were all within normal ranges. Mean platelet volume, plateletcrit, basophils percentage, absolute value of basophils, and mean corpuscular hemoglobin concentration were higher in the exposed group than in the control group (P<0.05). Platelet distribution widths were lower in the exposed group than in the control group and below the normal reference range (P<0.05). Conclusion PBDEs exposure in e-waste dismantling region tend to change platelet morphology, the number of basophils, and mean corpuscular hemoglobin concentration, and may pose potential health hazards to local residents.

Abstract
Objective: To evaluate the exported risk of COVID-19 from Hubei Province and the imported risk in various provinces across China. Methods: Data of reported COVID-19 cases and Baidu Migration Indexin all provinces of the country as of February 14, 2020 were collected. The correlation analysis between cumulative number of reported cases and the migration index from Hubei was performed, and the imported risks from Hubei to different provinces across China were further evaluated. Results: A total of 49 970 confirmed cases were reported nationwide, of which 37 884 were in Hubei Province. The average daily migration index from Hubei to other provinces was 312.09, Wuhan and other cities in Hubei were 117.95 and 194.16, respectively. The cumulative COVID-19 cases of provinces was positively correlated with the migration index derived from Hubei Province, also in Wuhan and other cities in Hubei, with correlation coefficients of 0.84, 0.84, and 0.81. In linear model, population migration from Hubei Province, Wuhan and other cities in Hubei account for 71.2%, 70.1%, and 66.3% of the variation, respectively. The period of high exported risk from Hubei occurred before January 27, of which the risks before January 23 mainly came from Wuhan, and then mainly from other cities in Hubei. Hunan Province, Henan Province and Guangdong Province ranked the top three in terms of cumulative imported risk (the cumulative risk indices were 58.61, 54.75 and 49.62 respectively). Conclusion: The epidemic in each province was mainly caused by the importation of Hubei Province. Taking measures such as restricting the migration of population in Hubei Province and strengthening quarantine measures for immigrants from Hubei Province may greatly reduce the risk of continued spread of the epidemic.

Abstract
OBJECTIVE To assess the accuracy of paralleling technique in measuring the depth of approximal infrabony pocket after periodontal flap surgery by comparing the measured and actual depths. METHODS The study population included 26 patients with infrabony defects who had undergone periodontal flap surgery, bone graft surgery, and guided tissue regene-ration. The measured and actual depths of approximal infrabony pocket after periodontal flap surgery were compared. The 26 infrabony defects were categorized into the following groups according to tooth position: anterior teeth, premolar, and molar groups, and according to type of infrabony pocket: one-walled, two-walled, and three-walled infrabony pocket groups. Paired t-test was used to detect the difference between the two values. RESULTS Depth measurements of the approximal infrabony pocket depth of the anterior teeth and premolar were not significantly different (P>0.05), whereas those of the molar group were significantly different (P<0.05). In addition, depth measurements in one-walled and two-walled infrabony pocket groups showed no significant differences (P>0.05), whereas those in the three-walled infrabony pocket group were significantly different (P<0.05). CONCLUSIONS Paral-leling technique can accurately measure the depth of approximal infrabony pockets of anterior teeth and premolar teeth that are one- or two-walled. However, this method cannot accurately measure the approximal infrabony pockets of molar teeth and three-walled infrabony pockets as indicated by significant differences in their depth measurements.

Abstract
Objective: To identify the definition of heat wave based on mortality risk assessment in different regions of China. Methods: Daily mortality (from China Information System for Disease Control and Prevention) and meteorological data (from National Meteorological Information Center in China) from 66 counties with a population of over 200 000 were collected from 2006-2011. With the consideration of climate type and administrative division, China was classified as seven regions. Firstly, distributed lag non-linear model (DLNM) was used to estimate community-specific effects of temperature on non-accidental mortality. Secondly, a multivariate meta-analysis was applied to pool the estimates of community-specific effects to explore the region-specific temperature threshold and the duration for definition of heat wave. Results: We defined regional heat wave of Northeast, North, Northwest, East, Central and Southwest China as being two or more consecutive days with daily mean temperature higher than or equal to the P(64), P(71), P(85), P(67), P(75) and P(77) of warm season (May to October) temperature, respectively, while the thresholds of temperature were 21.6, 23.7, 24.3, 25.7, 28.0 and 25.3 ℃. The heat wave in South China was defined as five or more consecutive days with daily mean temperature higher than or equal to the P(93) (30.4 ℃) of warm season (May to October) temperature. Conclusion: The region-specific definition of heat wave developed in our study may provide local government with the guidance of establishment and implementation of early heat-health response systems to address the negative health outcomes due to heat wave.

Abstract
BACKGROUND Members of B7 family are reported to regulate lymphocytes activation, transmit both costimulatory and co-inhibitory signals, control T cell-mediated immune responses and tolerance. Among which B7-H4 is reported to regulate the immune response negatively. OBJECTIVE To investigate the plasma concentration of soluble B7-H4 (sB7-H4) and its clinical significance in systemic lupus erythematosus (SLE). METHODS Fifty-six SLE patients with or without active SLE (ASLE) and 29 age- and gender-matched healthy volunteers were recruited. Plasma concentration of sB7-H4 was measured using sandwich ELISA kits. RESULTS Compared with healthy subjects, the concentration of sB7-H4 was significantly higher in patients with SLE (p=0.006). Plasma sB7-H4 concentration in patients with lupus nephritis (LN) were also significantly higher than healthy subjects (p=0.008), but no difference was found between LN and SLE patients without LN (non-LN). Additionally, the sB7-H4 concentration in patients was negatively correlated with the SLE disease activity index score (SLEDAI) (r=-0.3055, p=0.022). Compared with inactive disease, the concentration of sB7-H4 in ASLE patients was significantly lower (p=0.002). There were statistical significances between the positive and negative groups with decreased leukocytes or thrombocytes (p=0.012; p=0.033; respectively), but no statistically significant difference was found in other positive and negative serum laboratory indicators. CONCLUSIONS The increased level of sB7-H4 in patients suggests that this pathway might be involved in the pathogenesis of SLE. However, the exact mechanism or physiological role of sB7-H4 in SLE pathogenesis remains to be investigated.

Abstract
To investigate the clinical significance of the ratio of T helper cell 17 (Th17) cells to single immunoglobulin IL-1-related receptor (SIGIRR)+ cluster of differentiation (CD4)+ T cells in patients with systemic lupus erythematosus (SLE), novel data and data from previous studies were analyzed. The frequency of Th17 cells in peripheral blood mononuclear cells (PBMCs) and their correlation with clinical data were evaluated in 48 patients with SLE and 38 healthy controls through flow cytometry. Compared with healthy controls, the percentage of Th17 cells was significantly increased in the PBMCs of patients with SLE (Z=-5.82, P<0.001). Compared with inactive SLE (ISLE), the percentage of Th17 cells in active SLE (ASLE) were significantly increased (Z=-4.26, P<0.0001). Compared with patients without lupus nephritis, the frequency of Th17 cells was significant increased (Z=-2.20, P=0.028). The frequency of Th17 cells was inversely correlated with the frequency of SIGIRR+CD4+ T cells (r=-0.61, P<0.001). The ratio of Th17 cells to SIGIRR+CD4+ T cells in ASLE was significantly increased compared with healthy controls or patients with ISLE (P<0.001) and was inversely correlated with complement component 3 and complement component 4, and positively correlated with SLE disease activity index and 24-h proteinuria (P<0.05). In summary, increased numbers of Th17 cells and decreased numbers of SIGIRR+CD4+ T cells in patients with SLE suggested that SIGIRR+CD4+ T and Th17 cells may be involved in the pathogenesis of SLE.

Abstract
OBJECTIVE To explore associations between maternal and fetal vitamin D status in preeclamptic pregnancies. METHODS A case-control experiment was carried out with proportion ratio of 1:1 (controls: n = 60 vs cases: n = 60). Blood collection of both maternal and cord were performed before and during delivery, respectively, and 25(OH)D measurement was conducted. Difference analysis was performed according to returned data. Immunohistochemical analysis, together with semi-quantitative Western blot, was also performed to determine protein expression of vitamin D receptor in placenta and cord tissues of ESPE. RESULTS Mean ± SD values of maternal 25(OH)D in control and PE group were 38.06 ± 6.28 and 33.05 ± 4.10, respectively, and significant differences with P < 0.0001 were found between control and PE in both continuous and categorical variables, especially in ESPE subtype (32.96 ± 4.49). The deficiency category (< 30 nmol/L) showed increased odds of PE (OR, 2.83, 95% CI, 1.32-6.08) in both maternal 25(OH)D and cord 25(OH)D in multivariable logistic regression. Semi-quantitative analysis showed that expression of placenta VDR in the ESPE subgroup was significantly higher than that in control group with P < 0.001, while expression of umbilical vein VDR in ESPE subgroup was significantly higher than that in control group with P < 0.05. CONCLUSIONS The present study finds that lowest maternal and fetal vitamin D status in ESPE existed in the preeclampsia subsets. The VDR expression in placenta and fetus in ESPE were higher than that of normal pregnancy, which indicated that it might be related to placenta compensatory mechanism and is worthy of further research.

Abstract
OBJECTIVES To analyse the failure patterns and prognostic factors influencing survival in patients with primary mucosal melanoma of the nasal cavity and paranasal sinuses. MATERIALS AND METHODS Fifty-one patients were analysed retrospectively. Forty-eight, 33, 10, and 13 patients underwent surgery, radiotherapy, chemotherapy, and immunotherapy, respectively. Failure events, including local recurrence, regional relapse, distant metastases, and death, were examined. RESULTS During follow-up (median: 59.0 months), 36 patients experienced failure after treatment, including local (n = 17), regional (n = 8), and distant organ (n = 23) metastases. The median failure times for local, regional, and distant metastases were 13.0, 14.0, and 8.0 months, respectively. The median survival times from local, regional, and distant failure to death were 10.5, 8.0, and 4.0 months, respectively. The 5-year overall survival rates of patients with and without distant organ metastases were 14.4% and 72.6%, respectively (p < .001). Multivariate analyses showed that radiotherapy increased local recurrence-free and regional relapse-free survival. Patients with stage IV tumours had reduced distant metastasis-free and overall survival compared to patients with stage I-III tumours. CONCLUSIONS Distant metastasis was mainly owing to failure. Radiotherapy and the disease stage were prognostic factors for survival.

Abstract
Objective: To estimate the effect of daily diurnal temperature range (DTR) on mortality in different areas in China. Methods: A time series study using the data collected from 66 areas in China was conducted, and Meta-analysis was used to analyze the estimates of associations between DTR and daily mortality. Modifying effects of extremely low and high DTR-mortality relationship by season and socioeconomic status (SES) were also evaluated respectively. Cumulative excess risk (CER) was used as an index to evaluate the effects. Results: The information about 1 260 913 registered deaths were collected between 1 January 2006 and 31 December 2011, we found the relationship between extreme DTR and mortality was non-linear in all regions and the exposure-response curve was J-shaped. In central and south areas of China, the result indicated the obvious acute effect of extremely high DTR, and the mortality effect in central area (CER=5.1%, 95% CI: 2.4%-7.9%) was significant higher than that in south area (CER=4.5%, 95% CI: 1.7%-7.3%). Regarding to the modification of seasons, the cumulative mortality effect of DTR in cold season (CER=5.8%, 95%CI: 2.5%-9.2%) was higher than that in hot season (CER=3.1%, 95%CI: 1.1%-5.1%). Generally, deaths among the elderly (≥75 years) were associated more strongly with extremely high DTR. Conclusions: The mortality effects of extremely DTR in different areas and seasons showed different characteristics, that in central area and in cold season it was significantly stronger. After modified by season and SES, DTRs were the greatest threat to vulnerable population, especially to the elderly (≥75 years). Therefore, more attention should be paid to vulnerable groups and protection measures should be taken according to the local and seasonal conditions.

Abstract
Objective: To evaluate the effectiveness of health education about prevention of heat wave hazard in the elderly. Methods: A non-randomized controlled trial was conducted during the summer of 2015 among a sample of residents aged ≥60 years in Panyu district, Guangzhou. Eight intervention measures for heat wave hazard prevention were taken in intervention group for 3 months (from August to October) and in control group no intervention measures were taken. The comparison of intervention effects was conducted between the intervention group and control group with mixed effect model after the collection of related information with same questionnaire. Results: After adjusting of family per capita income, family air-condition availability, alcohol use, disease history and time, the average score of risk awareness in the intervention group increased by 1.62, while it was 0.51 in the control group, the difference was significant (t=2.76, P=0.006). A significant effect was observed in the intervention group on the reduction of hospitalizations due to chronic diseases. The hospitalization rate due to chronic diseases in resent 3 months in the intervention group decreased from 32.39% (46/142) before intervention to 28.87% (41/142) after intervention; while in the control group, it increased from 26.28% (41/156) before intervention to 36.53% (57/156) after intervention. There was no significant difference between the two groups in awareness of knowledge on heat wave hazard prevention and the score of adaptation to heat wave. Conclusion: Health education programs could improve the risk awareness on heat waves, and reduce the hospitalizations due to chronic diseases in the elderly.

Abstract
Background Although parotid-sparing IMRT decreased the dose distribution of parotid, parotid region recurrence has been reported. Prophylactic irradiation in parotid area would be necessary in patients with high risk of parotid lymph node metastasis (PLNM). This study was to detect the high-risk factors of PLNM in nasopharyngeal carcinoma. Methods This was a 1:2 case-control study. All patients in this study were newly diagnosed NPC with N2-3 classification from January 2005 to December 2012. Cases were 22 sides with ipsilateral PLNM. Controls were 44 patients who were randomly selected from N2-3 disease in database. Results 20/1096 (1.82 %) NPC patients were found PLNM. Sum of the longest diameter for multiple lymph nodes (SLD) in level II was larger in case group than that in control group (6.0 cm vs. 3.6 cm, p = 0.003). Level II lymph node necrosis, level Va/b involvement, and rare neck areas involvement were more common in case group (p = 0.016, p = 0.034, and p < 0.001, respectively). RPN, level III, and level IV metastases showed no significant difference between the two groups. Multivariate analysis in logistic regression showed that only SLD ≥5 cm in II area (OR = 4.11, p = 0.030) and rare neck areas involvement (OR = 3.95, p = 0.045) were associated with PLNM in NPC patients. Conclusions PLNM was an uncommon event in NPC patients. SLD ≥5 cm in level II and involvement in rare-neck areas may be potentially high-risk factors for PLNM. Sparing parotid in IMRT was not recommended for NPC patients with high risks of PLNM.

Abstract
OBJECTIVE To explore the outcome and prognostic factors of recursive partitioning analysis (RPA) Class III brain metastatic patients treated with stereotactic radiotherapy (SRT). MATERIALS AND METHODS Fifty-six consecutive patients with metastatic brain tumors and Karnofsky performance scale (KPS) scores <70 treated with SRT from January 2008 to October 2013 were involved in the analysis. Twenty-five patients (44.6%) were with symptomatic extracranial lesions (SELs), and the other 31 patients (55.4%) were without SELs. The detailed follow-up data of KPS scores were available in 44 patients. The KPS score drop time (KDT) was calculated as the time between SRT and 10 points drop of KPS scores compared to the baseline. Kaplan-Meier and Cox proportional hazards regression analyses were performed for univariate and multivariate analyses. RESULTS The median overall survival time was 5.0 months (95% confidence interval [CI] 3.42-6.59) for the whole group. In multivariate analysis, the presence of SELs (P = 0.007, relative risk = 4.44, 95% CI 1.036-20.818) was the independent prognosis factor for survival. Median survival time was 3 months for the patients with SELs, 8 months for the patients without SELs. The median KDT of the 44 patients was 3.0 months (95% CI, 1.927-4.073 months). Again only the presence of SELs (P = 0.001, OR = 6.622, 95% CI, 2.108-20.801) was significantly related to KDT in multivariate analysis. The median KDT of the patients with SELs was 1.5 months, which was 5 months for the patients without SELs. CONCLUSION The presence of SELs was a negative prognosis factor for the survival of RPA Class III brain metastatic patients. If RPA Class III brain metastatic patients were without SELs, SRT may be a reasonable treatment option, but if they had SELs, SRT may not be a reasonable treatment due to the short overall survival time and KDT.

Abstract
BACKGROUND The associations between rs6887695 and 3'-untranslated region (3'-UTR) single-nucleotide polymorphisms (SNPs) within interleukin-12B (IL-12B) and autoimmune diseases (ADs) remain controversial and inconclusive. The aim of this study was to evaluate the association between IL-12B (3'-UTR A/C and rs6887695 C/G SNPs) and ADs by meta-analysis. METHODS PubMed and EMBASE were exhaustively searched for studies on the association between IL-12B SNPs and ADs. Publication bias was examined by a funnel plot and Egger's test. The robustness of the pooled results was assessed by sensitivity analysis. A fixed- or a random-effects model was applied to calculate the pooled odds ratios (ORs). RESULTS A total of 34 studies were included in this meta-analysis. The pooled results demonstrated that IL-12B rs6887695 SNPs were significantly associated with the risk of ADs. However, there was no significant association between IL-12B 3'-UTR SNPs and ADs. When the studies were stratified by ethnicity, significant association between IL-12B 3'-UTR SNPs and ADs was observed in both Asian and European population. In addition, allele A within 3'-UTR of IL-12B gene was found to be a protective factor for T1DM, but a risk factor for psoriasis. CONCLUSION The IL-12B 3'-UTR and rs6887695 SNPs are associated with susceptibility to ADs.

Abstract
This study was designed to establish and validate a set of autoverification methods for hematology analysis. One thousand and twenty-four samples were selected from Shanghai Ruijin Hospital and 999 from Beijing Hospital, China. False positive, false negative and autoverification pass rates were verified and the rules were then adjusted and confirmed according to the verification results. After confirmation, at least 10,000 sample cases were selected from Shanghai Ruijin Hospital, Beijing Hospital and China Armed Police General Hospital and checked automatically. The differences in the autoverification pass rate and average report delivery time before and after the application of the autoverification methods were compared between the three hospitals. Preliminary validation results showed that the false negative rates of the Shanghai Ruijin Hospital and Beijing Hospital were less than 2%. The false positive rates of these two hospitals were high, close to 18%. After rule adjustment, the false negative rate was basically the same as before adjustment, but the false positive rate declined obviously while the pass rate of autoverification improved significantly. The autoverification pass rates of the three hospitals were 76.4%, 85.1% and 84.2%, respectively. The turnover time (TAT, time from receipt of sample to report of the result) of the three hospitals decreased by 4.1 min, 8.8 min and 10.2 min, respectively. Autoverification systems using a Mindray BC-6800 auto hematology analyzer and labXpert were confirmed as being effective in reducing TAT and enhancing working efficiency on the premise of ensuring low false negative rate.

Abstract
OBJECTIVE Esthesioneuroblastoma is a rare cancer. The purpose of this study was to review the long-term outcomes of patients with esthesioneuroblastomas (ENBs) who were treated at a single institution. MATERIALS AND METHODS One hundred thirteen patients with biopsy-proven ENBs between June of 1979 and November of 2014 were retrospectively reviewed. There was 1 patient at stage A, 23 stage B and 89 stage C according to Kadish classifications. The initial treatments included pre-operative radiotherapy (RT) followed by surgery in 11 patients, surgery followed by post-operative RT in 51, primary RT in 47, and surgery in 3, and only a single patient was treated with palliative chemotherapy alone. RESULTS The median follow-up was 75months, 5-year overall survival (OS), loco-regional control rate (LRC) and distant metastasis-free survival were 65%, 73% and 67%, respectively. The OSs at 5years were 91% in the pre-operative RT group, 82% in the post-operative RT group, and 50% in the primary RT group (p<0.001). Regarding the patients in early disease stages (Kadish A/B), no survival differences were observed between primary RT and combination treatment. Regarding the node-negative Kadish C disease patients, combination of surgery and RT elicited superior survival, and pre-operative RT yielded the best prognoses. Distant failure rate is over 60% for N-positive disease, chemotherapy may play a more important role. CONCLUSIONS The optimal treatment policy for ENBs remains the combination of surgery and radiotherapy. When choosing the most adequate therapy for ENBs, disease stage, age and lymph nodes status should be taken into consideration.

Abstract
BACKGROUND Vitamin D deficiency is common in pregnant women, but an optimal serum vitamin D level during pregnancy has not been determined and remains an area of active research. Vitamin D data from large populations of pregnant Chinese women are still limited. OBJECTIVE To evaluate the vitamin D status of women in Eastern China during the second trimester of pregnancy. METHODS A hospital-based, cross-sectional, observational study. Serum 25-hydroxyvitamin D [25(OH)D] concentration was measured in samples from 5823 pregnant women in Wuxi City, China (latitude: 31.5o N), from January 2011 to June 2012. RESULTS The median serum 25(OH)D concentration was 34.0 nmol/L [2.5 nmol/L 25(OH)D = 1 ng/mL 25(OH)D]. Vitamin D deficiency [defined as 25(OH)D < 30 nmol/L according to the Institute of Medicine (National Academy of Sciences, Washington, D.C., USA)] or inadequacy [25(OH)D of 30-49.9 nmol/L] was identified in 40.7% and 38.0% of the women, respectively. Only 0.9% had a 25(OH)D level ≥ 80.0 nmol/L, which is the concentration recommended as adequate by the Endocrine Society (Washington, D.C., USA). Compared with older women, younger women were more likely to be deficient in vitamin D. There were significant differences in the 25(OH)D levels according to season. The 25(OH)D levels reached peak values in September and were correlated with (r = 0.337, P < 0.001), and fluctuated with, average monthly air temperatures. CONCLUSIONS There is a high prevalence of Vitamin D deficiency among pregnant Chinese women, and 25(OH)D levels varied according to season and air temperature. The results of this study also suggest that currently there is a big gap between the levels of Vitamin D detected in pregnant Chinese women and the levels recommended by the Endocrine Society.

Abstract
Oxygen vacancies (VO) are known to be common native defects in zinc oxide (ZnO) and to play important roles in many applications. Based on density functional theory, we present a study for the migration of oxygen vacancies in ultra-thin ZnO nanowires (NWs). We find that under equilibrium growth conditions VO has a higher formation energy (Ef) inside the wire than that at shallow sites and surface sites, with different geometric relaxations and structural reconstructions. The migration of VO has lower barriers in the NW than in the bulk and is found to be energetically favorable in the direction from the bulk to the surface. These results imply a higher concentration of VO at surface sites and also a relative ease of diffusion in the NW structure. Our results support the previous experimental observations and are important for the development of ZnO-based devices in photocatalysis and optoelectronics.

Abstract
OBJECTIVE Patients with small-cell lung cancer (SCLC) are at high risk of developing brain metastases (BM). Fractionated stereotactic radiotherapy (FSRT) alone or combined with whole brain radiation therapy can be used to treat intracranial metastases. This study was aimed to explore FSRT for BM from SCLC. MATERIALS AND METHODS We retrospectively analyzed 45 patients with BM from SCLC treated with fractionated linear accelerator FSRT. Multivariate analysis was used to determine independent risk factors of overall survival (OS). RESULTS There were 35 patients treated with salvage FSRT and 10 patients treated with primary FSRT. The median OS was 10 months from the beginning of FSRT and 19 months from diagnosis of BM. The median OS of salvage FSRT group and primary FSRT group was 22 and 10 months from the diagnosis of BM, respectively (P = 0.011); 11 and 8 months from FSRT, respectively (P = 0.828). Recursive partitioning analysis class and the stage of the primary tumor were independent predictors of increased OS (relative risk [RR] = 2.634, P = 0.021 and RR = 2.324, P = 0.0210, respectively). CONCLUSIONS Salvage and primary FSRT were both effective treatment options for BM from SCLC. Salvage and primary FSRT may have different OS from the time of diagnosis of BM.

Abstract
PURPOSE To discuss the clinical characteristics and management of periparotid recurrence of nasopharyngeal carcinoma after definitive intensity-modulated radiotherapy. PATIENTS AND METHODS The authors retrospectively reviewed the charts of 716 patients with nasopharyngeal carcinoma who underwent intensity-modulated radiotherapy at their center from January 2005 through December 2010. Disease recurred in a spared parotid gland in 10 patients (1.4%). After periparotid recurrence, 4 patients received surgery alone, 1 patient received radiotherapy alone, 2 patients received chemotherapy alone, 2 patients received surgery plus chemotherapy, and 1 patient received surgery plus radiotherapy. RESULTS After a median follow-up of 42.6 months (19.8 to 86.0 months), 4 patients died of tumor progression. The median survival time after periparotid recurrence was 25.1 months (5.0 to 74.5 months). CONCLUSIONS Periparotid recurrence is an uncommon pattern of failure after definitive intensity-modulated radiotherapy for nasopharyngeal carcinoma, and there were some long-term survivors in this patient population after salvage treatment.

Abstract
BACKGROUND Local failure of nasopharyngeal carcinoma (NPC) after radiotherapy (RT) remains one of the major treatment failures. This study aimed to evaluate the clinical efficacy and complications of fractionated stereotactic radiotherapy (FSRT) with vagina carotica protection technique for local residual of NPC patients after the primary RT. METHODS From August 2006 to August 2010, FSRT with vagina carotica protection technique was applied to 36 patients in our department, the patients aged between 13 and 76 years with a median of 41.3 years, 25 of them were male and 11 were female. According to 2002 Union for International Cancer Control (UICC) Staging System, the stages before primary radiotherapy were: IIa 2, IIb 5, III 18, IVa 7, IVb 4. In the first course of radiotherapy, 9 patients received conventional RT, 27 patients received intensity modulated radiotherapy (IMRT) and 20 out of the 36 patients received concurrent chemoradiotherapy. The total dose in the first course of RT was 69.96 - 76.90 Gy (median, 72.58 Gy). The intervals between the primary RT and FSRT ranged from 12 to 147 days (median, 39.8 days). Target volumes ranged from 1.46 to 32.98 cm(3) (median, 14.94 cm(3)). The total FSRT doses were 10.0 - 24.0 Gy (median, 16.5 Gy) with 2.0 - 5.0 Gy per fraction. The most common regimen was 15 Gy in 5 fractions of 3 Gy, the irradiation dose to vagina carotica was less than 2 Gy per fraction. RESULTS The median follow-up time was 34 months (range, 12 - 59 months). The 3-year local control rate was 100%; the 3-year overall survival rate was 94.4%; the 3-year disease-free survival rate was 77.8%. In this study, we had one case of cranial nerve injury, two cases of temporal lobe necrosis, and no nasopharyngeal massive hemorrhage was observed. CONCLUSION FSRT with vagina carotica protection technique is an effective and safe RT regimen for local residual of NPC with reduction of radiation-related neurovascular lesions.

Abstract
BACKGROUND Metastatic lung cancer is one of the most common oncologic problems. This study aimed to evaluate the long-term clinical outcome of stereotactic body radiation therapy (SBRT) for metastatic lung tumors. METHODS We retrospectively reviewed the 71 patients with lung metastases, who had 172 lesions treated with SBRT from January 2000 to December 2006. All patients were unfit or failed after surgery and/or chemotherapy. The median total dose was 48 Gy (range, 30 - 60) in 4 (range, 2 - 12) fractions. The median size of the irradiated lesions was 2.1 cm (range, 0.9 - 7.9 cm). RESULTS All but two patients received follow up. The median follow-up time was 24.7 months (range, 2.9 - 114.4 months). The median follow-up time for living patients was 86.8 months (range, 58.1 - 114.4 months). The 1-, 3-, 5-year local control and overall survival rates were 88.8%, 75.4%, 75.4% and 78.9%, 40.8%, 25.2%. Multivariate analysis showed that the absence of extrapulmonary metastases (P = 0.024; hazard ratio (HR), 1.894; 95% confidence interval (CI), 1.086 - 3.303) and disease-free interval ≤ 12 months (P = 0.014; HR, 0.511; 95%CI, 0.299 - 0.873) were independent prognostic factors. No grade 3 or more acute and late toxicities occurred. Only one patient developed a non-symptomatic rib fracture. CONCLUSION SBRT could be an alternative treatment to surgery for subsets of patients with lung metastases with favorable long-term survival and tolerable complications.

Abstract
Many types of uterine packing are attempted to control PPH, including B-Lynch suture, Cho's suture, and so on. A female PPH caused by a low-lying placenta and placenta accreta did not respond to bimanual compression massage, administration of oxytocin and prostaglandins. A combination of B-Lynch with a modified Cho suture were tried to manage the PPH and succeeded. Combining sutures of B-Lynch with a modified Cho suture not only effectively manage PPH but also conserve the uterus, and avoid infection or adhesions of the endometria and empyema in the cavity of uterus.

Abstract
OBJECTIVE To study the relationship between the symptoms and prognosis of nasopharyngeal carcinoma (NPC). METHODS The clinical data of 905 M0 NPC patients who received radical radiotherapy from January 1990 to May 1999 were retrospectively studied. Nodal distribution, cranial nerve paralysis, as well as the relationship between symptom duration and prognosis were analyzed. RESULTS The most common symptom in patients with NPC is neck node metastasis, with an incidence of 40.0% at the time of diagnosis, followed by blood-staining sputum (18.7%) and aural symptoms (17.0%). Node metastasis in the lower neck and supraclavicular region alone was seen in 10 patients (1.1%). Cranial nerve paralysis was found in 179 patients (19.8%). The 5-year overall survival and disease-free survival were significant lower in symptom duration more than 6 months group than in less than 6 months group (71.2% vs 79.8%, P = 0.008 and 51.9% vs 63.6%, P = 0.0008); however, the local control rate between these two group was not significantly different (79.4% vs 83.5%, P = 0.138). CONCLUSION The symptom duration is associated with the prognosis of NPC. Early diagnosis and treatment are the most important factors in improving the prognosis of NPC.

Abstract
BslI is a thermostable type II restriction endonuclease with interrupted recognition sequence CCNNNNN/NNGG (/, cleavage position). The BslI restriction-modification system from Bacillus species was cloned and expressed in Escherichia coli. The system is encoded by three genes: the 2,739-bp BslI methylase gene (bslIM), the bslIRalpha gene, and the bslIRbeta gene. The alpha and beta subunits of BslI can be expressed independently in E. coli in the absence of BslI methylase (M.BslI) protection. BslI endonuclease activity can be reconstituted in vitro by mixing the two subunits together. Gel filtration chromatography and native polyacrylamide gel electrophoresis indicated that BslI forms heterodimers (alphabeta), heterotetramers (alpha(2)beta(2)), and possibly oligomers in solution. Two beta subunits can be cross-linked by a chemical cross-linking agent, indicating formation of heterotetramer BslI complex (alpha(2)beta(2)). In DNA mobility shift assays, neither subunit alone can bind DNA. DNA mobility shift activity was detected after mixing the two subunits together. Because of the symmetric recognition sequence of the BslI endonuclease, we propose that its active form is alpha(2)beta(2). M.BslI contains nine conserved motifs of N-4 cytosine DNA methylases within the beta group of aminomethyltransferase. Synthetic duplex deoxyoligonucleotides containing cytosine hemimethylated or fully methylated at N-4 in BslI sites in the first or second cytosine are resistant to BslI digestion. C-5 methylation of the second cytosine on both strands within the recognition sequence also renders the site refractory to BslI digestion. Two putative zinc fingers are found in the alpha subunit of BslI endonuclease.

Abstract
The genes encoding the ApaLI (5'-GTGCAC-3'), NspI (5'-RCATGY-3'), NspHI (5'-RCATGY-3'), SacI (5'-GAGCTC-3'), SapI (5'-GCTCTTCN1-3', 5'-N4GAAGAGC-3') and ScaI (5'-AGTACT-3') restriction-modification systems have been cloned in E. coli. Amino acid sequence comparison of M.ApaLI, M.NspI, M.NspHI, and M.SacI with known methylases indicated that they contain the ten conserved motifs characteristic of C5 cytosine methylases. NspI and NspHI restriction-modification systems are highly homologous in amino acid sequence. The C-termini of the NspI and NlaIII (5'-CATG-3') restriction endonucleases share significant similarity. 5mC modification of the internal C in a SacI site renders it resistant to SacI digestion. External 5mC modification of a SacI site has no effect on SacI digestion. N4mC modification of the second base in the sequence 5'-GCTCTTC-3' blocks SapI digestion. N4mC modification of the other cytosines in the SapI site does not affect SapI digestion. N4mC modification of ScaI site blocks ScaI digetion. A DNA invertase homolog was found adjacent to the ApaLI restriction-modification system. A DNA transposase subunit homolog was found upstream of the SapI restriction endonuclease gene.

Abstract
A 1440-bp plasmid named pAP12875 was isolated from Acetobacter pasteurianus and its nucleotide sequence determined. An open reading frame was found capable of coding for a protein that has similarity with the replication protein of pVT736-1 from Actinobacillus actinomycetemcomitans and the 32-kDa protein of phage Pf3 from Pseudomonas aeruginosa.

Abstract
A new E. coli strain has been constructed that contains the dinD1::LacZ+ fusion and is deficient in methylation-dependent restriction systems (McrA-, McrBC-, Mrr-). This strain has been used to clone restriction endonuclease genes directly into E. coli. When E. coli cells are not fully protected by the cognate methylase, the restriction enzyme damages the DNA in vivo and induces the SOS response. The SOS-induced cells form blue colonies on indicator plates containing X-gal. Using this method the genes coding for the thermostable restriction enzymes Taql (5'TCGA3') and Tth111l (5'GACNNNGTC3') have been successfully cloned in E. coli. The new strain will be useful to clone other genes involved in DNA metabolism.

Abstract
Wilms' tumor has been associated with deletions in two loci on chromosome 11, and the introduction of a translocated human chromosome [t(X;11)] into a Wilms' tumor cell line (G401.6TG.6) by microcell hybridization suppresses tumor formation in nude mice. The tumorigenic phenotype is restored in segregants of these microcell hybrids, in which the introduced chromosome is lost. We have used ultrahigh-resolution 'giant' two-dimensional gel electrophoresis of metabolically labeled cellular proteins and in vitro translation products of isolated mRNA to identify changes in cellular gene expression that occur in these cell lines. The changes in gene expression associated with these chromosomal manipulations per se are quite minimal. However, we have identified two proteins (p16 and p28) whose synthesis is consistently decreased in three non-tumorigenic (suppressed) microcell hybrid clones relative to parental and segregant tumorigenic lines. They are also decreased at the level of mRNA in at least two of the non-tumorigenic clones. The decrease of these proteins represents markers of the suppressed phenotype, and their down-regulation may conceivably mediate the suppression of tumorigenicity.
