OBJECTIVES: To examine the global, regional, and national disease burden of neonatal jaundice. METHODS: The 2019 Global Burden of Disease database was searched to collect incident cases/incidence and deaths/mortality of neonatal jaundice, as well as global socio-demographic index (SDI) and universal health coverage index (UHCI). The epidemiological trend of neonatal jaundice from 1990 to 2019 was analyzed. The correlations between incidence/mortality of neonatal jaundice and SDI and UHCI were evaluated. RESULTS: From 601 681 in 1990 to 626 005 in 2019, with a 4.04% increase in global incident cases of neonatal jaundice. The overall age-standardized incidence rate exhibited an increase [estimated annual percent change=0.13 (95%CI: 0.03 to 0.23)] during this period. Additionally, deaths due to neonatal jaundice decreased by 58.83%, from 128 119 in 1990 to 52 742 in 2019. The overall age-standardized mortality rate showed a decrease [estimated annual percent change=-2.78 (95%CI: -3.00 to -2.57)] over the same period. Countries with lower SDI, such as India, Pakistan, and Nigeria, reported a higher proportion of neonatal morbidity and mortality. In 2019, a negative correlation was observed between estimated annual percent change in age-standardized mortality rate and SDI (ρ=-0.320, P<0.05) or UHCI (ρ=-0.252, P<0.05). CONCLUSIONS: The global incidence of neonatal jaundice is on the rise, while the mortality rate is declining. The burden of neonatal jaundice is influenced by social development, economic factors, and the level of medical care.

Interfacially Polymerized ß-Cyclodextrin Film for Rapid Removal of Organic Dyes.

Porous cyclodextrin-based polymers are widely used for the rapid removal of organic pollutants in water. Traditional cyclodextrin-based polymers are prepared in the organic phase, which is time consuming and costly. Herein, a novel cyanuricchloride (TCT) cross-linked porous ß-cyclodextrin-based thin-film composite membrane is designed in the aqueous phase by interfacial polymerization. A self-standing TCT-CDP film is formed instantly at the surface of water phase at room temperature. Several different water-soluble organic dyes such as Methylene Blue, Neutral Red, Auramine, Brilliant Green, and Crystal Violet are selected for rejection study with TCT-CDP membrane. The effective rejection of TCT-CDP membrane for typical dyes is up to 99%, indicating TCT-CDP membrane exhibit excellent selectivity for separation of organic dyes from water.

Evaluation of abdominal compression-decompression combined with chest compression CPR performed by a new device: Is the prognosis improved after this combination CPR technique?

INTRODUCTION: This study was designed to compare the outcomes of standard cardiopulmonary resuscitation (STD-CPR) and combined chest compression and abdominal compression-decompression cardiopulmonary resuscitation (CO-CPR) with a new device following out-of-hospital cardiac arrest (OHCA). Moreover, we investigated whether patient prognosis improved with this combination treatment. METHODS: This trial was a single-centre, prospective, randomized trial, and a blinded assessment of the outcomes was performed. A total of 297 consecutive patients with OHCA were initially screened, and 278 were randomized to the STD-CPR group (n = 135) or the CO-CPR group (n = 143). We compared the proportions of patients who achieved a return of spontaneous circulation (ROSC), survived to hospital admission and survived to hospital discharge. In addition, we also performed the Kaplan-Meier analysis with a log-rank test at the end of the follow-up period to compare the survival curves of the two groups. RESULTS: The differences were not statistically significant in the proportion of patients who achieved ROSC [31/135 (23.0%) versus 35/143 (24.5%)] and survived to hospital admission [28/135 (20.7%) versus 33/143 (23.1%)] between the CO-CPR group and STD-CPR group. However, there was a significant difference in the proportion of patients who survived to hospital discharge [16/135 (11.9%) versus 7/143 (4.9%)] between the two groups. Nine patients (6.7%) in the CO-CPR group and 2 patients (1.4%) in the STD group showed good neurological outcomes according to the cerebral performance category (CPC) scale score, and the difference was statistically significant (P = 0.003). The Kaplan-Meier curves showed that the patients in the CO-CPR group achieved better survival benefits than those in the STD-CPR group at the end of the follow-up period (log-rank P = 0.007). CONCLUSION: CO-CPR was more beneficial than STD-CPR in terms of survival benefits in patients who have suffered out-of-hospital cardiac arrest.

Association between interleukin-10-819T/C polymorphism and risk of ischemic stroke: A meta-analysis.

BACKGROUND: The interleukin-10 (IL-10)-819T/C polymorphism has been indicated to be correlated with ischemic stroke susceptibility, but this relationship remains controversial. A meta-analysis was conducted to investigate the potential association between IL-10-819T/C polymorphism and ischemic stroke risk. METHODS: Databases including Pubmed, Embase, and CNKI were searched. Data were extracted and odds ratios (OR) with 95% confidence intervals (CI) were calculated. RESULTS: Eight case-control studies with 1832 cases and 1520 controls were included in this meta-analysis. IL-10-819T/C polymorphism may decrease the risk of ischemic stroke (C vs T: OR = 1.01, 95% CI: 0.91-1.12; CC vs TT: OR = 0.91, 95% CI: 0.73-1.14; CT vs TT: OR = 1.10, 95% CI: 0.95-1.28; CC + CT vs TT: OR = 1.06, 95% CI: 0.92-1.22; CC vs CT + TT: OR = 0.91, 95% CI: 0.75-1.11). In the stratified analysis by sample size, and case-control matched status, significant associations were still not observed in all genetic models. In the subgroup meta-analysis based on source of controls, IL-10-819T/C polymorphism had decreased ischemic stroke risk for recessive model in population-based controls' subgroup (CC vs CT + TT: OR = 0.69, 95% CI: 0.50-0.95), but not in the hospital-based controls' subgroup. In the stratified analysis based on ethnicity, IL-10-819T/C polymorphism had decreased ischemic stroke risk for recessive model in Asian populations (CC vs CT + TT: OR = 0.78, 95% CI: 0.62-0.99), but not in Caucasian populations. CONCLUSIONS: In conclusion, the results suggest that the IL-10-819T/C polymorphism is not associated with ischemic stroke risk. Larger scale studies are needed for confirmation.

Association between interleukin-10 -1082A/G polymorphism and risk of ischemic stroke: A meta-analysis.

The Interleukin-10 -1082A/G polymorphism has been indicated to be correlated with ischemic stroke susceptibility, but the results of studies are still debatable. Thus, a meta-analysis was carried out.Databases including PubMed, Embase, and CNKI were searched. Data were extracted and odds ratios (OR) with 95% confidence intervals (CI) were calculated.12 case-control studies with 2722 cases and 2405 controls were included in this meta-analysis. IL-10 -1082A/G polymorphism may decrease the risk of ischemic stroke (G vs A: OR = 0.72, 95% CI: 0.59-0.87; GG vs AA: OR = 0.59, 95% CI:0.48-0.74; AG vs AA: OR = 0.69, 95% CI: 0.51-0.93; GG+AG vs AA: OR = 0.65, 95% CI: 0.50-0.84; GG vs AG+AA: OR = 0.71, 95% CI: 0.55-0.93). Meanwhile, similar results were also observed in matched studies, hospital-based subgroup, Asians, and large sample-size studies.In conclusion, this meta-analysis suggested that the IL-10 -1082A/G polymorphism contributes to decreased ischemic stroke risk. Further large-scale and well-designed studies are still needed to confirm the results of our meta-analysis.

Association of monocyte chemoattractant protein-1-2518A/G polymorphism and risk of coronary artery disease among the Chinese population: a meta-analysis.

BACKGROUND: Numerous studies have evaluated the association between the MCP-1-2518A/G polymorphism and coronary artery disease (CAD) risk; however, the actual association is controversial. To derive a more precise estimation of the relationship in Chinese population, we performed this meta-analysis. METHODS: We searched the PubMed, Embase, Web of Science, and CNKI databases to identify studies that examined the association between the MCP-1-2518A/Gpolymorphism and the risk of CAD. We estimated the pooled odds ratio with its 95% confidence interval to assess this association. RESULTS: Seven studies containing 4024 Chinese subjects (2260 patients with CAD and 1764 controls) were included in this meta-analysis. MCP-1-2518A/G polymorphism was not found to be significantly associated with CAD risk in all comparisons (for G vs A: OR=1.10, 95% CI=0.92-1.32; for AG+GG vs AA: OR=1.10, 95% CI=0.79-1.53; for GG vs AA+AG: OR=1.05, 95% CI=0.91-1.21; for GG vs AA: OR=1.12, 95% CI=0.82-1.54; for AG vs AA: OR=1.05, 95% CI=0.76-1.47). Similarly, no associations were found in subgroup analysis based on source of control and endpoint. CONCLUSIONS: the MCP-1-2518A/G polymorphism was not associated with the risk of CAD in Chinese population.

To identify Candidatus Neoehrlichia mikurensis infection in northeastern China, we tested blood samples from 622 febrile patients. We identified in 7 infected patients and natural foci for this bacterium. Field surveys showed that 1.6% of ticks and 3.8% of rodents collected from residences of patients were also infected.

[Dynamic investigation on the co-infection status of two pathogens in ticks from tourist point in Heilongjiang province].

OBJECTIVE: To monitor the co-infection status of Borrelia burgdorferi sensu lato (B.b.s.l) and spotted fever group Rickettsia (SFGR) in tourist areas of Heilongjiang province. METHODS: Polymerase chain reaction (PCR) was used to detect the 5S-23S rRNA intergenic spacer of B.b.s.l and ompA of SFGR in ticks, dynamically collected from tourist areas of Heilongjiang province in 2010. Amplification products from positive ticks were sequenced, and phylogenetic analysis was conducted by Mega 5.0 software package. RESULTS: 849 ticks were collected from two tourist points, with the dominant ticks in Tiger Mountain and Jingpo Lake were Ixodes persulcatus and Haemaphysalis concinna. Regarding the Ixodes persulcatus from Tiger Mountain, the infection rates of B.b.s.l and SFGR were 26.15% and 10.05%. The infection rate of SFGR was 13.33% in Haemaphysalis concinna and the B.b.s.l was undiscovered in the same ticks from Jingpo Lake. However, the co-infection could only be detected in Ixodes persulcatus of both tourist areas. Surveillance data showed that the major ticks were more likely to be appeared in July at Tiger Mountain and in June at Jingpo Lake. Data from the sequence analysis on B.b.s.l showed that the B.b.s.l in tourist areas could be classified into three different genotypes, other than B. garinii and B. afzelii. We first detected B. valaisiana-like group genotype in northeast of China. Results from the sequence analysis of SFGR positive products showed that the two DNA sequences of newly detected agents were completely the same as Rickettsia sp. HL-93 which was detected in Hulin and Rickettsia sp. H820 found in northeast, China. CONCLUSION: The co-infection of B.b.s.l and SFGR was detected in ticks from the tourist areas of Heilongjiang province, and data from the sequencing of specific fragment showed that various kinds of genotypes existed in this area. However; the rates of co-infections-different according to environment, time and population that contributed to the kinds of and the index of ticks existed in the surveys points, also the infection rate of the ticks was studied.

[Meta-analysis of intervention effects on obesity in Chinese pupils].

OBJECTIVE: To comprehensively evaluate the effect of interventions on obesity in Chinese pupils. METHODS: A literature research was carried out in China National Knowledge Infrastructure, Wanfang Data, VIP Database for Chinese Technical Periodicals, PubMed and the Excerpts Medica Database (EMBASE) databases to collect articles published between 1979 and 2010 concerning the effect of interventions for preventing obesity in Chinese pupils. Rate difference (RD) of the rate of obesity as the evaluation indicator was selected to Meta-analyze the effect of interventions on obesity. There are total 215 articles, in which 211 articles were written in Chinese and other articles were written in English. RESULTS: 17 literatures were used for Meta-analysis by the uniform inclusion and exclusion criteria. The results showed that the RD of obesity rate for the students in the intervention group was 3% (95%CI: 1% - 5%) after the intervention. However, the RD of obesity rate for the students in the control group was -2% (95%CI: -4% - -1%) after the intervention. Results of stratified analysis for the RD of obesity rate showed that the obesity rate for the students in the intervention group were decreased significantly after the intervention of combined programs with health education, physical exercise and nutrition interventions with moderate intervention time (1 to 2 years), the RD (95%CI) of obesity rate were 5% (2% - 8%), 3% (1% - 4%), respectively. For the studies whose baseline obesity rates was insignificant difference between the intervention group and the control group, the obesity rate for the students in the intervention group was 4% (95%CI: -7% - -1%) lower than the obesity rate for the students in the control group after the intervention. CONCLUSION: Health-education-based comprehensive intervention is effective on obesity prevention in Chinese pupils; combined intervention programs with moderate intervention time (1 to 2 years) were effective in improving efficiency of obesity prevention in pupils.

[Meta-analysis on the relationship between leptin receptor Gln223Arg and Pro1019Pro gene polymorphism and obesity in the Chinese population].

OBJECTIVE: To evaluate the associations between polymorphisms of LEPR Gln223Arg, LEPR Pro1019Pro and the risk on obesity. METHODS: A computerized search on literature was carried out in Wanfang, CNKI, VIP databases and CBM, PubMed, EMBASE databases to collect articles published between 1979 and 2010 concerning the associations between polymorphisms of LEPR Gln223Arg and/or LEPR Pro1019Pro and risk of obesity in the Chinese population. Odds ratios (ORs) were used to assess the strength of the association, and 95% confidence intervals (CIs) to present the precision of the estimates. Meta-analysis was performed using the STATA statistical software. RESULTS: Fifteen literature were collected for Meta-analysis by the uniform inclusion and exclusion criteria. There were 1096 obese patients and 949 controls for polymorphisms of LEPR Gln223Arg in 9 papers, together with 961 obese patients and 818 controls for polymorphisms of LEPR Pro1019Pro in 8 papers. Overall, there were significant associations between decreased risk of obesity and LEPR Gln223Arg polymorphisms (-668 A→G) (G versus A, OR = 0.66, 95%CI: 0.49 - 0.89; AG and GG versus AA, OR = 0.50, 95%CI: 0.32 - 0.77; respectively). There were significant associations between increased risk of obesity and LEPR Pro1019Pro polymorphisms (-3057 G→A) (A versus G, OR = 1.61, 95%CI: 1.15 - 2.26; AG and AA versus GG, OR = 1.50, 95%CI: 1.08 - 2.08; respectively). CONCLUSION: Variant alleles at both LEPR-668 and LEPR-3057 were associated with obesity in the Chinese Han-dominated population.
