ABSTRACT
Objective:To investigate the impact and interaction of Toll like receptor 2 (TLR2) and interferon regulatory factor 5 (IRF-5) gene polymorphisms on the susceptibility to neonatal sepsis.Methods:A total of 78 cases of neonatal septicemia patients admitted to Baoding Children′s Hospital from July 2018 to August 2021 were prospectively selected as the study group, and 78 cases of healthy newborns in the same period were selected as the control group. The TLR2 and IRF-5 gene polymorphisms and the levels of inflammatory markers [C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] in different genotypes of infants were compared between the two groups. We evaluated the relationship between TLR2 and IRF-5 genotypes, inflammatory markers, and susceptibility to neonatal sepsis, and analyzed the interaction between their gene polymorphisms and susceptibility to neonatal sepsis.Results:There were significant differences in the distribution of TLR2 (rs3804099) and IRF-5 (rs2004640) loci genotype and Allele frequency between the two groups (all P<0.05); The serum CRP, TNF-α, and IL-6 levels in children with TLR2 (rs3804099) genotype TT genotype [(111.12±30.87)mg/L, (77.50±20.02)pg/ml, (40.27±11.31)pg/ml] were higher than those in children with CC/CT genotype [(72.46±24.51)mg/L, (54.18±17.65)pg/ml, (28.34±9.05)pg/ml], and the differences were statistically significant (all P<0.05). The serum CRP, TNF-α, and IL-6 levels [(113.90±28.94)mg/L, TNF-α (79.84±19.82)pg/ml, IL-6 (41.05±11.49)pg/ml] in children with the IRF-5 (rs2004640) TT genotype were higher than those in children with the GG/GT genotype [(70.88±22.16)mg/L, (52.27±16.73)pg/ml, (27.96±9.75)pg/ml], and the differences were statistically significant (all P<0.05). The TT genotypes at TLR2 (rs3804099) and IRF-5 (rs2004640) loci were positively correlated with serum CRP, TNF-α, and IL-6 levels (all P<0.05); The TT genotypes at TLR2 (rs3804099) and IRF-5 (rs2004640) loci were independent risk factors for susceptibility to neonatal sepsis (all P<0.05); The TT genotype at the TLR2 (rs3804099) locus and the TT genotype at the IRF-5 (rs2004640) locus exhibited a positive interaction in susceptibility to neonatal sepsis ( OR=7.467, γ=1.728). Conclusions:TLR2 (rs3804099) TT genotype and IRF-5 (rs2004640) TT genotype significantly increase the susceptibility to neonatal sepsis, and there is a positive interaction between the two.
ABSTRACT
Objective:To analyze the epidemic dynamics and characteristics of human brucellosis in Jinzhong City, Shanxi Province, and to provide scientific basis for formulating prevention and control measures.Methods:Brucellosis epidemic data from "China Disease Prevention and Control Information System" from 2013 to 2020 and the surveillance data of brucellosis prevention and control in Jinzhong City over the years were collected, and the epidemiological characteristics, serological and pathogenic monitoring results of brucellosis in Jinzhong City were analyzed.Results:A total of 5 235 cases of brucellosis were reported in Jinzhong City from 2013 to 2020, with an average annual incidence of 19.60/100 000. There was a statistically significant difference in the annual incidence of each year (χ 2 = 561.09, P < 0.001). Pingyao County had the largest number of reported cases (903 cases), and Yushe County had the highest incidence (59.78/100 000). The incidence was observed in every month of the past years, with significant seasonal onset, the peak of the incidence was from March to July, accounting for 60.50% (3 167/5 235). The majority of the patients were male, aged 20 - 60 years, and farmers, accounting for 81.07% (4 244/5 235), 85.06% (4 453/5 235) and 81.34% (4 258/5 235), respectively. Epidemiological investigation revealed 33 522 high-risk occupational groups. Serological examination was performed in 24 544 people, with a positive rate of 4.45% (1 091/24 544). In 263 pathogenic culture samples, 52 strains of Brucella were found, with a detection rate of 19.77%, all of them were sheep type 3. Conclusions:In recent years, the epidemic of brucellosis in Jinzhong City has shown a sporadic trend, with significant regional differences in the incidence. The occupational population is still the focus of prevention and control. It is suggested to carry out occupational population monitoring, do a good job in health education and behavioral intervention, timely learn about the epidemic dynamics, and effectively control the brucellosis epidemic.
ABSTRACT
Background Neonicotinoid insecticides (NEOs) are emerging synthetic insecticides that have been used in various pest management regimens worldwide as alternatives to conventional insecticides. Recently, several studies have indicated that humans are widely exposed to NEOs, but limited is known about the levels and associated health risks of NEOs exposure among children. Objective To estimate exposure levels of four kinds of NEOs in urine samples among 5-year-old children from Laizhou Wan, Shandong Province, and to evaluate health risks of single and cumulative exposure to NEOs among children in this area. Methods A total of 205 children who participated in the 5-year-old follow-up in Laizhou Wan Birth Cohort (LWBC) were included. Urinary concentrations of four NEOs [imidacloprid (IMI), acetamiprid (ACE), clothianidin (CLO), and thiamethoxam (THM)] were measured by high-performance liquid chromatography coupled with triple quadrupole mass spectrometry. Based on the detected NEOs concentrations, estimated daily intake (EDI) was calculated, and the health risk of exposure to single NEO was assessed using hazard quotient (HQ, risk threshold=1). A relative potency factor (RPF) approach was used to standardize the concentrations of the four NEOs by IMI to calculate their cumulative concentrations. Then, the health risk of cumulative exposure to the four NEOs was further evaluated based on the HQ method. Results The detection rates of the four NEOs in the 5-year-old children were all above 90%, and their median creatinine-adjusted urinary concentrations were in the order from high to low as follows: CLO (1.373 μg·g−1) > THM (0.628 μg·g−1) > IMI (0.310 μg·g−1) > ACE (0.073 μg·g−1). Of the four NEOs, the median EDI of IMI was 0.035 µg·kg−1·d−1, higher than those of CLO (0.032 µg·kg−1·d−1), THM (0.012 µg·kg−1·d−1), and ACE (0.002 µg·kg−1·d−1). The maximum HQ values of IMI, CLO, THM, and ACE were 0.168, 0.152, 0.055, and 0.022, respectively, which were all far lower than the risk threshold of 1. The median concentration of cumulative exposure to the four NEOs standardized by IMI was 21.241 μg·g−1, and its median EDI was 2.370 µg·kg−1·d−1. The maximum HQ of cumulative exposure to the four NEOs was only 0.694, which also did not exceed the risk threshold of 1. Conclusion NEOs exposure is common among the 5-year-old children in Laizhou Wan, Shandong. Although there is no obvious health risk associated with single and cumulative exposure to NEOs in the children in this area, their exposure levels of NEOs are higher than those in some foreign areas. The adverse health effects of long-term exposure to low dose of NEOs deserve our extensive attention.
ABSTRACT
Objective: To analyze the epidemiological characteristics of norovirus-caused acute gastroenteritis outbreaks in China, identify the factors influencing the scale of outbreaks, and provide scientific evidences for early control of norovirus infection outbreaks. Methods: The descriptive epidemiological analysis approach was applied to analyze the incidence of national norovirus infection outbreaks by using the data from the Public Health Emergency Event Surveillance System in China from January 1, 2007 to December 31, 2021. The unconditional logistic regression model was applied to analyze the risk factors that affected the outbreaks' scale. Results: A total of 1 725 norovirus infection outbreaks were recorded in China from 2007 to 2021, with an upward trend in the number of the reported outbreaks. The southern provinces had their annual outbreak peaks from October to March; the northern provinces had two outbreak peaks from October to December and from March to June annually. The outbreaks occurred mainly in southeastern coastal provinces with a trend of gradual spread to central, northeastern and western provinces. The outbreaks mainly occurred in schools and childcare setting (1 539 cases, 89.22%), followed by enterprises and institutions (67 cases, 3.88%) and community households (55 cases, 3.19%). Human to human transmission was the main infection route (73.16%), and norovirus GⅡ genotype was the predominate pathogen causing the outbreaks (899 cases, 81.58%). The time interval between the onset of the primary case and the outbreak reporting M (Q1, Q3) was 3 (2, 6) days and the case number of the outbreak M (Q1, Q3) was 38 (28, 62). The timeliness of outbreak reporting was improved in recent years and the scale of the outbreaks showed a decreasing trend over the years, the differences in reporting timeliness and outbreak scale among different settings were significant (P<0.001). The factors that affected outbreaks' scale included the outbreak setting, transmission route, outbreak reporting timeliness and type of living areas (P<0.05). Conclusions: From 2007 to 2021, the number of the norovirus-caused acute gastroenteritis outbreaks increased in China and the more areas were affected. However, the outbreak scale showed a decreasing trend and the outbreak reporting timeliness was improved. It is important to further improve the surveillance sensitivity and reporting timeliness for the effective control of the outbreak scale.

Objective: To analyze the incidence trend and epidemiological characteristics of typhoid fever and paratyphoid fever in China from 2004 to 2020, understand the high-incidence population and hotspot areas, and provide evidences to develop more targeted prevention and control measures. Methods: The descriptive epidemiological method and spatial analysis method were applied to analyze the epidemiological characteristics of typhoid fever and paratyphoid fever in China during this period by using the surveillance data collected from the National Notifiable Infectious Disease Reporting System of Chinese Center for Disease Control and Prevention. Results: A total of 202 991 cases of typhoid fever were reported in China from 2004 to 2020. More cases occurred in men than in women (sex ratio: 1.18∶1). Most cases were reported in adults aged 20-59 years (53.60%). The incidence rate of typhoid fever decreased from 2.54/100 000 in 2004 to 0.38/100 000 in 2020. The highest incidence rate was reported in young children aged <3 years after 2011, ranging from 1.13/100 000 to 2.78/100 000, and during this period the proportion of cases in this age group increased from 3.48% to 15.59%. The proportion of the cases in the elderly aged ≥60 years increased from 6.46% in 2004 to 19.34% in 2020. The hotspot areas existed in Yunnan, Guizhou, Guangxi and Sichuan Provinces and expanded to Guangdong, Hunan, Jiangxi, and Fujian Provinces. A total of 86 226 paratyphoid fever cases were reported from 2004 to 2020, the male to female ratio of the cases was 1.21∶1. Most cases were reported in adults aged 20-59 years (59.80%). The incidence rate of paratyphoid fever decreased from 1.26/100 000 in 2004 to 0.12/100 000 in 2020. The highest incidence rate of paratyphoid fever was in young children aged <3 years after 2007, ranging from 0.57/100 000 to 1.19/100 000, and during this period the proportion of the cases in this age group increased from 1.48% to 30.92%. The proportion of the cases in the elderly aged ≥60 years increased from 4.52% in 2004 to 22.28% in 2020. The hotspot areas expanded to the east, including Guangdong, Hunan and Jiangxi Provinces, from Yunnan, Guizhou, Sichuan, and Guangxi Provinces. Conclusions: The results showed a low level of incidence of typhoid fever and paratyphoid fever in China with a trend of decreasing per year. The hotspots were mainly in the of Yunnan, Guizhou, Guangxi and Sichuan Provinces, with an expanding trend to eastern China. It is necessary to strengthen the typhoid fever and paratyphoid fever prevention and control in southwestern China, among young children aged <3 years and the elderly aged ≥60 years.

Objective:To investigate the effect of posterior nasal neurectomy（PNN） with pharyngeal neurectomy （PN） on chronic sinusitis with nasal polyps （CRSwNP）complicated with perennial allergic rhinitis （PAR）. Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery（FESS）+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups（P>0.05）. However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group（P<0.05）. Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

The continuous pandemic coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)is a serious threat to human life and health because of high infectious pathogenicity, and it also has posed a new challenge to the current medical model. Many literatures have shown that these changes range from the more common ocular surface diseases such as inflammation of the cornea, conjunctiva, and sclera, to the relatively rare paracentral acute middle maculopathy and acute macular neuroretinopathy. For patients with ocular symptoms as the first or accompanying symptoms of SARS-CoV-2 infection, how to identify the correlation between ocular manifestations and SARS-CoV-2 infection is undoubtedly a serious challenge for ophthalmologists. In this review, the ocular pathology caused by both SARS-CoV-2 infection and vaccination was discussed, covering pathological changes in the ocular surface, uvea, retina and macula, and cranial nerves.
ABSTRACT
Objective:To investigate the effect of liraglutide(LRG) on high glucose-induced oxidative stress injury in(H9c2) cardiomyocytes and its underlying mechanisms.Methods:A high glucose treatment was applied to H9c2 cells for 24 hours to establish an in vitro model of myocardial cell injury. Different concentrations of liraglutide(10, 100, 1000 nmol/L) were administered for intervention. Cell viability was evaluated using the CCK-8 assay, and changes in cell morphology were observed under an inverted microscope. After 24 hours of liraglutide(100 nmol/L) intervention following high glucose treatment, the levels of lactate dehydrogenase(LDH), superoxide dismutase(SOD), and malondialdehyde(MDA) in the cell supernatant were measured. RT-PCR and Western blotting were used to detect the mRNA and protein levels of silent information regulator factor 1(SIRT1) and forkhead box protein O1(FOXO1). Western blotting was also used to assess the acetylation level of FOXO1 protein. Small interfering RNA(siRNA) technology was employed to silence SIRT1 in H9c2 cells to confirm its role in the study. Results:Compared to the control group, the high glucose group showed decreased cell viability, cell structure damage, increased levels of LDH and MDA in the cell supernatant, decreased SOD levels, aggravated oxidative stress, decreased SIRT1 expression, and increased acetylation level of FOXO1(all P<0.05). Compared to the high glucose group, liraglutide intervention resulted in increased cell viability, improved cardiac cell morphology, reduced oxidative stress levels, increased SIRT1 expression, and decreased acetylation level of FOXO1(all P<0.05). When SIRT1 was downregulated, the protective effects of liraglutide were weakened(all P<0.05). Conclusions:Liraglutide has a protective effect against high glucose-induced oxidative stress injury in H9c2 cells, which may be associated with the upregulation of SIRT1 expression.
ABSTRACT
The lens of the eye has been recognized as one of the most radiosensitive tissues. It has been known that a radiation dose of 0.5 Gy or higher can induce radiation cataract. Studies have also demonstrated that long-term exposure to low-dose radiation can increase the risk of lens opacity. However, the specific biologic mechanism of lens opacity induced by low-dose ionizing radiation is still unclear. Many mechanism chains may induce opacity independently or jointly, such as genomic damage in lens epithelial cells, oxidative stress, defects in intercellular communication, and inflammatory reaction, and genetic and epigenetic factors may also play a role. This paper briefly reviews the mechanisms of low-dose ionizing radiation inducing lens opacity as well as the role of genetic susceptibility in its development and progression, in order to provide a scientific reference for the prevention and control of this disease.
ABSTRACT
Objective:To explore the characteristics of intestinal flora in female patients with type 2 diabetes mellitus (T2DM) with comorbid coronary heart disease.Methods:Female patients with T2DM from September 2019 to November 2020 were enrolled in this study and divided into 2 groups stratified by coronary heart disease: 22 patients with coronary heart disease(T2DM+ CHD group) and 49 patients with simple T2DM group(T2DM group). Thirty-one healthy females were selected as the normal control group(NC group). The abundance of intestinal flora, the difference in intestinal flora and its relationship with indicators such as glycosylated hemoglobin and fasting blood glucose was analyzed by the real-time fluorescent quantitative PCR detection technology in the three groups.Results:The abundance of Prevotella in the T2DM group was lower, and Roseburia inulinivorans and Faecalibacterium prausnitzii in the T2DM+ CHD group were lower, while Bacteroides and Enterococcus spp in the T2DM+ CHD group were higher compared with NC group, respectively( P<0.05). The abundance of Bacteroides and Enterococcus spp in the T2DM+ CHD group was lower than that in the T2DM group( P<0.05). Spearman correlation analysis showed that the abundance of Faecalibacterium prausnitzii and Eubacterium rectale was negatively correlated with obesity while abundance of Bacteroides and Enterococcus spp was positively correlated with HbA 1C and fasting blood glucose. The abundance of Bacteroides was positively correlated with TCH and TG(all P<0.05). Logistic regression analysis showed that Bacteroides and Enterococcus spp were independent influencing factor of the development of female patients with T2DM and CHD. Conclusion:Female T2DM and T2DM with CHD had intestinal flora imbalance, which was related to a variety of glucose and lipid metabolism indicators, and might be closely related to the occurrence of T2DM and CHD. Bacteroides and Enterococcus spp were independent influencing factors of the development of female patients with T2DM and CHD. Regulating the intestinal flora can provide ideas for the prevention and treatment of T2DM with CHD in female.
ABSTRACT
Thyroid-associated ophthalmopathy(TAO)is an organ-specific autoimmune disease, which will cause a series of symptoms to significantly reduce the health level and life quality of patients. The pathogenesis of TAO has not been fully clarified. At present, there is a lack of unified and mature treatment scheme of it. Indeed, T-helper 17 lymphocyte(Th17)cells, regulatory T(Treg)cells and their imbalance are closely related to the immunological pathogenesis of TAO. It is currently believed that the cytokines secreted by Th17 cells can not only promote the inflammatory response of TAO and the fibrosis of orbital connective tissue, but also inhibit the adipogenic differentiation of TAO orbital connective tissue. In addition, Treg cells mainly exert immunosuppressive effect on TAO and delay the disease progression. At the same time, there is a dynamic balance relationship between Th17 and Treg cells, the imbalance of Th17/Treg cells can trigger the occurrence and development of TAO. This paper mainly expounds the influence mechanism of Th17, Treg cells and their balance on TAO, and analyzes the reasons for the differences between different research results, so as to provide some reference for the study of the pathogenesis and clinical treatment of TAO.
ABSTRACT
Background Exercise during pregnancy is closely related to maternal and infant health. Previous studies in developed countries have linked maternal exercise during pregnancy with newborn body weight as well as subcutaneous fat thickness. However, the relevant studies in China are limited, and the conclusions remain inconsistent. Objective To investigate the effects of maternal exercise during pregnancy on neonatal weight and subcutaneous fat thickness. Methods Based on the Shanghai Birth Cohort, 959 maternal-infant pairs were included in this study. The International Physical Activity Questionnaire was used to collect average weekly frequency and daily minutes of walking in the first and second trimesters, and entropy weight method was used to calculate the cumulative exercise index in the two trimesters. Birth weight was measured using a calibrated weigh scale. Subcutaneous fat thickness was measured at abdomen, scapula, and triceps with a Harpenden skinfold caliper for all newborns and the sum of the thickness for the three sites was then calculated. A multiple linear regression model was employed to estimate the relationships of cumulative exercise index during pregnancy with neonatal body weight and subcutaneous fat thickness. Subgroup analyses stratified by pre-pregnancy body mass index (BMI) and sex of newborns were also performed. Results The mean age of pregnant women was (28.5±3.8) years, and the pre-pregnancy BMI was (21.4±3.0) kg·m−2. Newborn boys were slightly more than newborn girls (54.3% vs 45.7%), and the neonatal weight was (3374.0±427.5) g. The means of newborns' abdominal, scapular, and triceps subcutaneous fat thickness were (4.4±1.3), (5.4±1.4), and (6.0±1.5) mm, respectively, and the sum of subcutaneous fat thickness was (15.8±3.9) mm. In the first and second trimesters, 77.3% and 88.7% of pregnant women walked 4 d per week and more, respectively; the daily minutes of walking was (36.9±27.2) min and (43.3±26.3) min, respectively; the cumulative exercise index was 25.6±17.7 and 35.9±21.1, respectively. The results of multiple linear regression analysis showed that the cumulative exercise index in the second trimester was negatively associated with newborns' abdominal (b=−0.006, 95%CI: −0.010-−0.003), scapular (b=−0.005, 95%CI: −0.009-−0.002), triceps (b=−0.006, 95%CI: −0.010-−0.002), and their sum of (b=−0.018, 95%CI: −0.028-−0.007) subcutaneous fat thickness (P<0.05); in the first and second trimesters, however, the relationship between maternal cumulative exercise and newborns' body weight was not significant. The results of stratified analyses showed that the negative associations between maternal cumulative exercise index and newborns' subcutaneous fat thickness for the second trimester remained significant in the subgroups of boys and neonates whose mothers had normal pre-pregnancy BMI (P<0.05). Conclusion Cumulative exercise index in the second trimester is negatively correlated with the neonatal thickness of subcutaneous fat, and the association may be altered by neonatal sexes and maternal pre-pregnancy BMI levels.
ABSTRACT
Exposure to environmental pollutants imposes important health risks to human beings. In recent years, emerging evidence has suggested that nutritional components may ameliorate the adverse health effects of environmental pollutants. Therefore, it raises great public health interests in protecting human health from environmental pollutants by nutrition interventions. Considering in vivo and in vitro experimental evidence, as well as epidemiological studies, this paper reviewed the possible mechanisms underlying how nutritional components counteract the adverse health impacts of environmental pollutants, which can provide directions for further studies on health risk assessment and nutrition intervention associated with environmental pollutant exposure.
ABSTRACT
Per-and polyfluoroalkylated substances (PFASs) are a group of persistent organic pollutants that are widespread in the environment and organisms. Given their unique hydrophobicity, oil-repellence, and chemical stability, PFASs are widely used in various industrial and commercial products. PFASs can accumulate and be biomagnified through the food chain, and its toxic effects have posed a certain threat to human health. The response of the immune system to PFASs exposure is one of the most sensitive human health effects, and has attracted remarkable attention from related scientists and organizations. We summarized international and domestic epidemiological studies on the associations between exposure to PFASs and immune system, including immunosuppression and immunoenhancement. We also reviewed experimental evidence of PFASs on immune system from perspectives of immune organs, immune cells, and cytokines. Furthermore, the possible mechanisms of peroxisome proliferator-activated receptor-α (PPAR-α)-dependent, nuclear factor-κB (NF-κB)-activated, and mitochondrial apoptosis pathways were summarized. While the relationships between PFASs and immune-related diseases in human are not yet conclusive, accumulative epidemiological studies provide evidence for associations between PFASs and reduced immune response to vaccination in children. In addition, previous studies mainly focus on the immunotoxicity of traditional PFASs, and our understanding of the molecular mechanism of the effects of PFASs on immune system is still in its infancy. Therefore, it is necessary to further explore the immunotoxicity of new PFASs and associated mechanism.

CT plain scan and MRI indicated blood clots in renal pelvis, and pericardium and pleural effusion. Renal arteriography indicated multiple venous fistula in both kidneys. Enhanced CT scan showed multiple small aneurysms in abdominal aortic branches, bilateral renal arteries and pancreatic arteries. The diagnosis of nodular polyarteritis was confirmed. Glucocorticoid and immunosuppressive agents were given. Meanwhile, highly selective renal arteriovenous fistula embolization was performed, Postoperative hematuria was effectively controlled, and the general condition was gradually improved. The patient was followed up for 2 months, and the condition was stable.
ABSTRACT
Objective:To observe the dynamic changes of platelet counts in septic shock patients within first week, and to explore their predictive value for prognosis.Methods:Retrospective analysis of clinical data of patients with septic shock admitted to the department of intensive care unit (ICU) of the First Affiliated Hospital of University of Science and Technology of China from January 2020 to December 2021 was conducted. The baseline data on gender, age and primary diseases, clinical indicators on infection site, pathogenic microbial type, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA), laboratory indicators and the trend of platelet count (PLT) on day 1, 3, 5 and 7 admitting ICU and patients prognosis of in-hospital were collected. Binary Logistic regression was used to assess the independent risk factors of in-hospital death in septic shock patients. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive power of each index for in-hospital mortality.Results:A total of 193 patients with sepsis were enrolled. Among them, 73 patients died and 120 patients survived. Univariate analysis showed that the age, proportion of hypertension and respiratory system infection, APACHE Ⅱ score, SOFA score and blood lactic acid (Lac) in the death group were significantly higher than those in the survival group, while the proportion of urinary system infection, white blood cell (WBC) and neutrophil (NEU) were significantly lower in the death group. Within 7 days after admitting ICU, the platelet (PLT) firstly decreased and then rebounded in the survival group, whereas it's showed a continuous downward trend in the death group. And the PLT count in both day 5 and 7 were significantly higher in the survival group compared with the dead group [×10 9/L: 94.5 (54.0, 182.0) vs. 50.0 (30.5, 87.5), 135.0 (86.8, 205.8) vs. 46.0 (23.5, 71.5), all P < 0.05]. Multivariate binary Logistic regression analysis showed that age [odds ratio ( OR) = 1.059, 95% confidence interval (95% CI) was 1.002-1.118], hypertension ( OR = 6.108, 95% CI was 1.340-27.851), respiratory system infection ( OR = 5.300, 95% CI was 1.116-25.118), APACHE Ⅱ score ( OR = 1.158, 95% CI was 1.054-1.273), SOFA score ( OR = 1.494, 95% CI was 1.060-2.107) and PLT on day 7 after admitting ICU ( OR = 0.926, 95% CI was 0.894-0.958) were independent risk factors for in-hospital prognosis in septic shock patients (all P < 0.05). ROC analysis showed that APACHE Ⅱ score, SOFA score and PLT on day 7 after admitting ICU all had good predictive value for in-hospital prognosis in septic shock patients, and the area under the ROC curve (AUC) of PLT on day 7 (AUC = 0.899, 95% CI was 0.857-0.941) was significantly higher than that of APACHE Ⅱ score (AUC = 0.748, 95% CI was 0.680-0.816), SOFA score (AUC = 0.767, 95% CI was 0.702-0.833). Conclusions:Clinicians should pay close attention to the dynamic changes of platelet counts in septic shock patients, especially the platelet counts on day 7 after admitting ICU. And active intervention should be provided to improve the prognosis.
ABSTRACT
OBJECTIVE@#To observe the clinical efficacy of different treatment frequency of auricular bloodletting combined with auricular point sticking for acne vulgaris.@*METHODS@#A total of 90 patients with acne vulgaris were randomized into a treatment group 1 (30 cases, 2 cases dropped off), a treatment group 2 (30 cases, 4 cases dropped off) and a treatment group 3 (30 cases, 5 cases dropped off). Combination therapy of auricular bloodletting and auricular point sticking at Fei (CO14), Shenmen (TF4), Neifenmi (CO18) and Shenshangxian (TG2p) were given once a week, twice a week and 3 times a week in the treatment group 1, the treatment group 2 and the treatment group 3 respectively, 4 weeks were as one course and totally 3 courses were required in the 3 groups. Before treatment and after 1, 2, 3 courses of treatment, the scores of global acne grading system (GAGS), skin lesion and quality of life-acne (QoL-Acne) were observed, the clinical efficacy was evaluated after 3 courses of treatment and the recurrence rate was evaluated in follow-up of 1 month after treatment in the 3 groups.@*RESULTS@#Compared before treatment, the scores of GAGS and skin lesion were decreased at each time point in the 3 groups (P<0.05), the QoL-Acne scores were increased after 1 course of treatment in the treatment group 3 and after 2, 3 courses of treatment in the 3 groups (P<0.05). There were no statistical differences in scores of GAGS, skin lesion and QoL-Acne among the 3 groups (P>0.05). There were no statistical differences in effective rate and recurrence rate among the 3 groups (P>0.05).@*CONCLUSION@#Different frequency of auricular bloodletting combined with auricular point sticking have similar efficacy in treating acne vulgaris, all can improve the skin lesion and quality of life in patients with acne vulgaris, and have a cumulative effect and good long-term curative effect.

Objective To investigate the prevalence of allergic and infectious diseases in children， and to assess the influence of indoor and outdoor environmental factors on these two common diseases in children. Methods A questionnaire was used to investigate the prevalence of allergic and infectious diseases in 140 children of 7 years old in Laizhou Bay， Shandong Province. Logistic regression was used to analyze the associations between indoor and outdoor environmental factors and children’s allergic and infectious diseases， respectively. Results The prevalence of previous eczema and other allergic diseases for the past year in children was 37.9% and 15.0%， respectively， and the prevalence of infectious diseases for the past year was 35.7%. As for allergic diseases， eye irritation due to outdoor air （ OR =2.977； 95% CI ： 1.407‒6.296） and nose irritation due to outdoor air （ OR =5.147； 95% CI ： 1.272‒20.827） were the risk factors for previous eczema in children. Indoor musty taste increased the risks of urticaria （ OR =4.306； 95% CI ： 1.062‒17.454） and previous eczema （ OR =3.853； 95% CI ： 1.080‒13.743）. The use of cockroach killers indoors increased the risk of rhinitis （ OR =6.102； 95% CI ：1.297‒28.697）. As for infectious diseases， having outdoor pollution sources increased the risk of gastrointestinal infection （ OR =4.937； 95% CI ： 1.050‒23.216）， and the use of mosquito coils and clothing mothproofing agents increased the risks of respiratory （ OR =6.333； 95% CI ： 1.397‒28.714） and gastrointestinal infections （ OR =3.218； 95% CI ： 1.074‒9.644）， respectively. However， we did not find associations between indoor passive smoking and allergic or infectious diseases. Conclusion Except outdoor passive smoking， all the other indoor and outdoor environmental factors increase the risks of children’s allergies and infectious diseases.
