Jiang J, Luo L, Xu P, Wang P. How does social development influence life expectancy? A geographically weighted regression analysis in China. Public Health 2018; 163:95-104. [PMID: 30121438 DOI: 10.1016/j.puhe.2018.06.003] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Revised: 05/17/2018] [Accepted: 06/04/2018] [Indexed: 11/16/2022]
Abstract
OBJECTIVES This study aimed to examine how social development influenced life expectancy from a spatio-temporal perspective. STUDY DESIGN Data were taken from the China Statistical Yearbooks for 2001 and 2011, which presented results from 2000 to 2010, respectively. METHODS A geographically weighted regression method was performed. A total of 31 provinces were treated as units of our analysis, and four social development dimensions were extracted by exploratory factor analysis. RESULTS Generally speaking, healthcare and education development could significantly improve life expectancy. Between 2000 and 2010, the positive effects of social harmony and eco-environment development were gradually increasing. Spatially speaking, the enhancing effect of healthcare development on life expectancy generally declined from south to north China; the improving effect of education development generally declined from southwest China to northeast and northwest China. The geographical distributions of the effects of eco-environment and social harmony development on life expectancy were different between 2000 and 2010; the former declined from the eastern coast to west China in 2000 and declined from northwest to south China in 2010, while the latter first declined from north to southwest China in 2000 and then declined from southwest to northeast China in 2010. CONCLUSIONS Because the effects of various social development dimensions on life expectancy vary with time and space, it is necessary to improve certain aspects of social development in specific areas and social stages to efficiently improve life expectancy and population health.

Abstract
Objective: The goal of this research was to understand the demographic distribution and related factors of non-marital and non-commercial heterosexual transmission (non-commercial transmission) for HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome). Methods: Data related to HIV/AIDS infected by non-marital heterosexual transmission and whose present address was in Qian Dongnan, were collected from Information System on the HIV/AIDS Prevention and Control. Information included demographic characteristics, the members of non-marital sex partners, transmission path, detection source, CD4(+)T lymphocyte level, et al. cases belong to homosexual history, injective drug use or non-classified non-marital heterosexuality transmission were excluded, totally collect HIV/AIDS 919 cases. Multivariate logistic regressions were used to analyze potential factors associated with non-marital and non-commercial heterosexual transmission. In addition, in March and June 2017, using a convenience sampling, we conducted one-to-one interviews among 10 HIV/AIDS who were infected by non-marital heterosexuality and had non-marital and non-commercial heterosexual experience in Kaili Center for Disease Control and Prevention. The content of the interview included basic information, sexual orientation, the main place of making friends and sexual behavior, attitude to commercial heterosexuality and non-martial and non-commercial heterosexuality and so on. Results: Out of the 919 cases, 645 (70.2%) were male, the proportion of non-commercial transmission was 55.06% (506). The proportion of female HIV/AIDS with non-commercial transmission was 84.7% (232), which was higher than male (42.5%(274)) (χ(2)=138.35, P<0.001). The proportion of Han HIV/AIDS with non-commercial transmission was 61.5% (275), which was higher than other religion (52.2%(412)) (χ(2)=6.32, P=0.012). The proportion of HIV/AIDS with non-commercial transmission who had 0-5 non-marital sexual partners was 58.8% (498), which was higher than who had>5 non-marital sexual partners (11.1%(8)) (χ(2)=61.10, P<0.001). The proportion of HIV/AIDS with non-commercial transmission who lived mobile was 72.9% (94), which was higher than who lived fixedly (52.2%(412)) (χ(2)=19.34, P<0.001). Qualitative interviews results revealed that the age of the respondents were 22-69. Respondents whose ages are in 22-34 were more likely to use mobile phone (4/10) and respondents whose ages are in 35-69 were less likely to look partners through party and the context of working. Conclusion: The proportion of cases being infected by non-marital and non-commercial heterosexual transmission in Qian dongnan was higher than general national levels. The characteristics of sex, marriage status, migration, vocation, the members of non-marital sex partners were significant differed between commercial heterosexual transmission and non-marital and non-commercial heterosexual transmission.

Abstract
Objective: To investigate the reliability of the distance between the tip of the greater trochanter and inter-teardrop line (GT-IT) in evaluating the leg length discrepancy (LLD) in patients underwent total hip arthroplasty (THA). Methods: Patients who underwent THA in Xi'an Honghui Hospital from August 2015 to February 2016 were enrolled in this study.The patients were measured for bilateral hips anterior-posterior (AP) radiograph preoperatively and postoperatively.Four distances measured, included: GT-IT, the tip of lesser trochanter and bi-ischial line (LT-BI); LT-IT and the anterior superior iliac spine and the medial malleolus (ASIS-MM). Magnification factor was considered when calculating absolute values.Intraclass correlation coefficient (ICC) was used to detect the reliability of the measurement data.Single factor analysis and paired t test were performed to compare data among the methods. Results: The ICC values of the four groups were greater than 0.80, which showed excellent agreement in the measurements.Single factor analysis of variance showed there were no statistically significant differences in the LLDs of the four groups preoperatively and postoperatively (F=0.914, 0.886, both P>0.05). There was no significant differences in preoperative and postoperative LLD between group GT-IT and group ASIS-MM, LT-BI or LT-IT(t=-1.544-1.114, all P>0.05). The LLDs were comparable between group LT-BI, ASIS-MM and LT-IT both preoperatively and postoperatively (t=1.577, 0.976, 1.344, -0.087, all P>0.05). And the LLD in group LT-IT and ASIS-MM were equivalent preoperatively and postoperatively (t=0.130, 1.063, both P>0.05). Bland-Altman plot illustrated high level of agreements between the four methods. Conclusion: Great reliability can be obtained with the GT-IT in evaluating the LLD in patients undergoing THA.

Abstract
Synthetic LAPONITE®-clay particles with platelet-like shape display strong aging when dispersed in aqueous solutions, preventing the latter from reaching their natural liquid-crystalline equilibrium state. Here we introduce a facile method that successfully prevents this aging behaviour and enables accessing the systems' liquid-crystal and crystalline phases. We graft the comb-like polymer PLL-PEG (poly(l-lysine)-g-poly(ethylene glycol)) onto the clay surfaces from solution, thereby screening the negative surface charges and thus ensuring steric stabilisation. We show zeta-sizer and rheology measurements, respectively, confirming complete steric coating and that aging of dilute samples is completely suppressed even after a year. Using evaporation as a means to concentrate the particles, we observe various liquid crystalline textures under a polarized optical microscope (POM). Upon sequential spreading and drying, we are also able to obtain transparent films with hierarchical architecture.

Abstract
Objective: To study the characteristics of social relations and relative factors among MSM in Guangzhou. Methods: Data was collected through a cross-sectional study in Guangzhou from November 2016 to May 2017. Sample size was estimated and participants were recruited from the voluntary counseling and testing services (VCT) which were set for MSM population, by nongovernmental organizations (NGOs) and the Centers for Disease Control and Prevention (CDC). Social ties and demographic characteristics of the respondents and their sexual partners were analyzed through both Chi square test and generalized estimating equations (GEE). Results: A total of 1 073 MSM, together with their nominated 4 301 partners were successfully recruited and involved in this study. Age (OR=1.2, P=0.01) and non-internet based intercourse (OR=1.65, P<0.01) were easy to form close relation with strong ties. Compared with MSM traditional venues (chess and cards room, tea room bathhouse, club), general public venue (bars, KTV, parks, shopping malls, schools, restaurants) (OR=1.46-3.12, P<0.01) showed close relation with strong ties. Our finding showed that MSM at the age of 18-25 preferred to build weak ties with the older MSM, while the 26-30-year-olds and 31-40-year-olds prefer to establish weak ties with younger partners but the 41-50-year-olds preferred to develop weak ties with one that were ten years younger. Conclusions: Clusters were noticed in the MSM populations when grouping and making friends with ones at different age. Characteristics regarding the relationship between sexual partners in choosing venues and ways of dating were different. Targeted intervention programs need to be explored innovatively.

Abstract
BACKGROUND Little is known about the pathogenesis of acute lung injury (ALI) complicated with acute aortic dissection (AAD). OBJECTIVE We aim to investigate the roles of macrophages-derived matrix metalloproteinase 9 (MMP9) in the development of ALI complicated with AAD and factors involved in the recruitment of macrophages. METHODS This study included three parts: (i) Determination of serum MMPs, angiotensin II (AngII) and MCP-1 in patients with AAD complicated with ALI or AAD only, non-ruptured chronic aortic aneurysm patients or healthy volunteers using ELISA method. (ii) A novel AAD complicated with ALI model was established by infusing angiotensin II (AngII) to immature rats treated with β-aminopropionitrile monofumarate (BAPN) to identify the potential roles of MMP9 and MCP-1 in AAD complicated with ALI. (iii) Cultured pulmonary microvascular endothelial cell (PMVEC) line was used to investigate how AngII was involved in the release of MCP-1 in rat pulmonary vascular endothelial cells. RESULTS Serum MMP9, AngII and MCP-1 were remarkably elevated in patients with AAD complicated with ALI. The MMP9 expressed in pulmonary tissues was derived from macrophages. In the animal model, the release of MMP9 from macrophages finally resulted in ALI, while inhibition of MMP9 and MCP-1 contributed to decreased incidence of AAD complicated with ALI. In vitro experiments indicated that AngII triggered overexpression of MCP-1 in PMVECs by activating NF-κB signaling pathway. CONCLUSION AAD complicated with ALI is highly associated with the macrophages infiltrating the pulmonary interstitial tissue and released MMP9 in response to angiotensin II. MCP-1 is closely related to the recruitment of macrophages.

Abstract
Objective: To investigate the safety and efficacy of hysterosopic management of type Ⅱ cesarean scar pregnancy (CSP) and the value of prophylactic uterine artery embolization (UAE). Methods: Totally 104 patients with type Ⅱ CSP treated with hysteroscopic surgery at the Women's Hospital, School of Medicine, Zhejiang University, during Jan. 2009 to Jun. 2016 were analyzed retrospectively, 67 patients combined with UAE (UAE group) and 37 patients without combined with UAE (non-UAE group). Laparoscopy or sonography guidance was conducted simultaneously. The following clinical parameters were compared, including: primary cure rate, uterine packing rate, uterine perforation rate, hemoglobin level change, the time for the mass absorption and the return of β-hCG to normal, complications, hospital days and hospital stay cost. Results: Median gestational age, size of mass, thickness of the anterior myometrium and β-hCG level in UAE group versus non-UAE group were 47 versus 47 days, 30 versus 30 mm,2 versus 2 mm, 36 524 versus 32 226 U/L (all P>0.05). Out of 104, 100 patients were managed successfully with hysteroscopic surgery, and 4 patients transformed to laparoscopic or laparotomy surgery. Hysteroscopic surgery was effective in 63 out of 67 patients (94%) in UAE group and 34 out of 37 patients (92%) in non-UAE group (P>0.05). There was no significant differences regarding uterine perforation rate, uterine packing rate, hemoglobin change and recovery time between UAE group and non-UAE group (all P>0.05). The median hospital day was 7 days in UAE group versus 5 days in non-UAE group (P<0.01). The median hospital stay cost was 13 654 yuan in UAE group versus 9 108 yuan in non-UAE group (P<0.01). Serious complication occurred in 4 patients (6%, 4/67) in UAE group and 2 patients (5%, 2/67) in non-UAE group (P=0.906). Conclusions: Hysteroscopic surgery is effective and safe for patients with type Ⅱ CSP in the first trimester with size ≤30 mm in diameter and gestation age<7 weeks. The value of prophylactic UAE is uncertain.

Abstract
Background: Cell cycle regulation of neural progenitor cells (NPCs) is an essential process for neurogenesis, neural development, and repair after brain trauma. Stromal cell-derived factor-1 (SDF-1, CXCL12) and its receptors CXCR4 and CXCR7 are well known in regulating the migration and survival of NPCs. The effects of CXCL12 on NPCs proliferation, cell cycle regulation, and their associated signaling pathways remain unclear. Cyclin D1 is a protein required for progression through the G1 phase of the cell cycle and a known downstream target of β-catenin. Therefore, cyclin D1 plays critical roles of cell cycle regulation, proliferation, and survival in NPCs. Methods: Primary mouse NPCs (mNPCs) were derived from brain tissues of wild-type, Cxcr4 knockout, or Cxcr7 knockout mice at mouse embryonic day 13.5 (E13.5). Flow cytometry was used to perform cell cycle analysis by quantitation of DNA content. Real-time PCR and Western blot were used to evaluate mRNA and protein expressions, respectively. Ki67 immunostaining and TUNEL assay were used to assess the proliferation and survival of mNPCs, respectively. Results: CXCL12 pretreatment led to the shortening of G0/G1 phase and lengthening of S phase, suggesting that CXCL12 regulates cell cycle progression in mNPCs. Consistently, CXCL12 treatment increased the expression of CyclinD1 and β-catenin, and promoted proliferation and survival of mNPCs. Cxcr7 knockout of mNPCs blocked CXCL12-mediated mNPCs proliferation, whereas Cxcr4 knockout mNPC did not significantly effect CXCL12- mediated mNPCs proliferation. Conclusion: CXCR7 plays an important role in CXCL12-mediated mNPC cell cycle regulation and proliferation.

Abstract
INTRODUCTION The laminoplasty has been the most widely used surgical method for OPLL. In recent years, increasing attention has been drawn to the anterior operative approaches for surgical treatment of cervical OPLL. However, which method is the optimum selection for therapy of cervical OPLL is still obscure. Therefore, we performed this prospective nonrandomized clinical study in patients with multilevel cervical myelopathy due to OPLL and compare the therapeutic efficiency of laminoplasty and anterior approach (cervical discectomy and/or cervical corpectomy) in the management of multilevel cervical OPLL. HYPOTHESIS There is no difference in clinical effects between anterior cervical spine surgery and laminoplasty in the treatment of multilevel cervical OPLL. MATERIAL AND METHODS A total of 150 consecutive patients with multilevels of cervical OPLL underwent anterior approaches (ACDF, ACCF and HDF) from July 2010 to June 2014, which were enrolled in this study. During the same period, one hundred and two patients receiving the laminoplasty were enrolled in the study. The clinical effects, alignment and range of motion (ROM) of cervical spine in patients of the anterior group and posterior group were assessed, respectively. The effects of high signals in T2 weighed MRI scans and percentage of spinal canal stenosis in these patients were also evaluated. Finally, postoperative complications regarding each group were analyzed. RESULTS Although significant differences in types of OPLL and preoperative sagittal alignment of cervical spine occurred in the two groups (P<0.05), clinical effects of the two groups were similar (P>0.05). The cervical curvature in laminoplasty group showed significant decrease at final follow-up (P<0.05). For ROM of cervical spine, no significant alteration was observed in both groups. The high T2 weighed signals and rate of spinal canal stenosis can influence clinical effects of both anterior group and laminoplasty group. In addition, significantly higher complication rate was observed in laminoplasty group compared with anterior group (P<0.05). DISCUSSION Both anterior and laminoplasty approaches can be considered effective and safe procedures in the treatment of the multilevel OPLL. However, the anterior approach with relatively lower incidence of postoperative complications is a better choice for cases with poor cervical curvature and serious spinal canal stenosis. TYPE OF STUDY AND LEVEL OF PROOF Level 3 nonrandomized, controlled clinical trials.

Abstract
Even though the oral microbiome is one of the most complex sites on the body it is an excellent model for narrow‐spectrum antimicrobial therapy. Current research indicates that disruption of the microbiome leads to a dysbiotic environment allowing for the overgrowth of pathogenic species and the onset of oral diseases. The gram‐negative colonizer, Porphyromonas gingivalis has long been considered a key player in the initiation of periodontitis and Streptococcus mutans has been linked to dental caries. With antibiotic research still on the decline, new strategies are greatly needed to combat infectious diseases. By targeting key pathogens, it may be possible to treat oral infections while allowing for the recolonization of the beneficial, healthy flora. In this review, we examine unique strategies to specifically target periodontal pathogens and address what is needed for the success of these approaches in the microbiome era.

Abstract
The aim of this study was to evaluate the application of delayed expansion of the alveolar ridge in dental implantation. This method avoids the need to harvest autogenous bone and the requirement to fix a block with screws, and could help prevent the uncontrolled fracture and avascular necrosis that may result from the traditional alveolar split. Eighteen patients and 43 implants were included in this retrospective study. The width of the alveolar ridge was measured before implantation, immediately after implantation, and after the final restoration. The width increased significantly after the insertion of implants and decreased slightly after bone remodelling. Overall, the width of the alveolar ridge increased by 2.37±1.44mm on average, ranging from -0.20mm to 5.75mm. The results suggest the use of delayed expansion for horizontal alveolar bone augmentation; however, the maxillary premolar area may not be a suitable site.

Abstract
Objective: To understand the rate of follow-up lost in men who have sex with men (MSM) in a gay bathhouse cohort study in Tianjin and the associated factors. Methods: The open cohort study in gay bathhouse was launched in 2012 in Tianjin, and the MSM for baseline survey were recruited from January to June 2012, while the follow up was carried out every six months. A questionnaire survey and HIV test were conducted in the study. The MSM who were HIV negative in the baseline survey in 2012 were used for follow up lost analysis. Univariate and multivariate logistic regression analysis were conducted to identify the factors associated with the lost of follow-up. Results: A total of 658 gay bathhouse patrons were recruited in the baseline survey, at the end of 42-month follow-up period, 173 of them dropped out (26.3%). Multivariate analysis showed that the MSM who were local residents (OR=0.552, 95%CI: 0.377-0.808), in Han ethnic group (OR=0.197, 95% CI: 0.066-0.593), having received HIV test in the last year (OR=0.481, 95% CI: 0.326-0.710), were male sex workers (OR=0.127, 95% CI: 0.028-0.585), and believed to be at high risk for HIV infection (OR=0.285, 95% CI: 0.125-0.647). They were more likely to receive follow-up but the MSM who were aged ≥35 years (OR=1.891, 95%CI: 1.022-3.500) were more likely to be lost in the follow-up. Conclusion: The lost rate of follow-up in MSM in the gay bathhouse cohort was high in Tianjin. Age, household registration, history of HIV test, the awareness of the risk to be infected with HIV and commercial homosex were factors associated with the follow-up rate in the MSM. It is necessary to conduct similar cohort study in targeted population on the basis of findings of this study.
