Abstract
Objective: To investigate the clinical characteristics of pediatric methicillin-resistant Staphylococcus aureus (MRSA) infection and the antibiotic sensitivity of the isolates. Methods: The clinical data of children with MRSA infection and antibiotic sensitivity of the isolates from 11 children's hospitals in Infectious Diseases Surveillance of Paediatrics (ISPED) group of China between January 1, 2018 and December 31, 2018 were collected retrospectively. The children's general condition, high-risk factors, antimicrobial therapy and prognosis, differences in clinical disease and laboratory test results between different age groups, and differences of antibiotic sensitivity between community-acquired (CA)-MRSA and hospital-acquired (HA)-MRSA were analyzed. The t test and Wilcoxon rank sum test were used for statistical analysis of the quantitative data and Chi-square test were used for comparison of rates. Results: Among the 452 patients, 264 were males and 188 were females, aged from 2 days to 17 years. There were 233 cases (51.5%) in the ≤1 year old group, 79 cases (17.5%) in the>1-3 years old group, 29 cases (6.4%) in the >3-5 years old group, 65 cases (14.4%) in the >5-10 years old group, and 46 cases (10.2%) in the>10 years old group. The main distributions of onset seasons were 55 cases (12.2%) in December, 47 cases (10.4%) in February, 46 cases (10.2%) in November, 45 cases (10.0%) in January, 40 cases (8.8%) in March. There were 335 cases (74.1%) CA-MRSA and 117 (25.9%) cases HA-MRSA. Among all cases, 174 cases (38.5%) had basic diseases or long-term use of hormone and immunosuppressive drugs. During the period of hospitalization, 209 cases (46.2%) received medical interventions. There were 182 patients (40.3%) had used antibiotics (β-lactams, glycopeptides, macrolides, carbapenems, oxazolones, sulfonamides etc) 3 months before admission. The most common clinical disease was pneumonia (203 cases), followed by skin soft-tissue infection (133 cases), sepsis (92 cases), deep tissue abscess (42 cases), osteomyelitis (40 cases), and septic arthritis (26 cases), suppurative meningitis (10 cases). The proportion of pneumonia in the ≤1 year old group was higher than the >1-3 years old group,>3-5 years old group,>5-10 years old group,>10 years old group (57.5% (134/233) vs. 30.4% (24/79), 31.0% (9/29), 38.5% (25/65), 23.9% (11/46), χ(2)=17.374, 7.293, 7.410, 17.373, all P<0.01) The proportion of skin and soft tissue infections caused by CA-MRSA infection was higher than HA-MRSA (33.4% (112/335) vs. 17.9% (21/117), χ(2)=10.010, P=0.002), and the proportion of pneumonia caused by HA-MRSA infection was higher than CA-MRSA (53.0% (62/117) vs. 42.1% (141/335), χ(2)=4.166, P=0.041). The first white blood cell count of the ≤1 year old group was higher than that children > 1 year old ((15±8)×10(9)/L vs. (13±7)×10(9)/L, t=2.697, P=0.007), while the C-reactive protein of the ≤1 year old group was lower than the 1-3 years old group,>5-10 years old group,>10 years old group (8.00 (0.04-194.00) vs.17.00 (0.50-316.00), 15.20 (0.23-312.00), 21.79(0.13-219.00) mg/L, Z=3.207, 2.044, 2.513, all P<0.05), there were no significant differences in procalcitonin (PCT) between different age groups (all P>0.05). After the treatment, 131 cases were cured, 278 cases were improved, 21 cases were not cured, 12 cases died, and 10 cases were abandoned. The 452 MRSA isolates were all sensitive to vancomycin (100.0%), linezolid (100.0%), 100.0% resistant to penicillin, highly resistant to erythromycin (85.0%, 375/441), clindamycin (67.7%, 294/434), less resistant to sulfonamides (5.9%, 23/391), levofloxacin (4.5%, 19/423), gentamicin (3.2%, 14/438), rifampicin (1.8%, 8/440), minocycline (1.1%, 1/91). The antimicrobial resistance rates were not significantly different between the CA-MRSA and HA-MRSA groups (all P>0.05). Conclusions: The infection of MRSA is mainly found in infants under 3 years old. The prevalent seasons are winter and spring, and MRSA is mainly acquired in the community. The main clinical diseases are pneumonia, skin soft-tissue infection and sepsis. No MRSA isolate is resistant to vancomycin, linezolid. MRSA isolates are generally sensitive to sulfonamides, levofloxacin, gentamicin, rifampicin, minocycline, and were highly resistant to erythromycin and clindamycin. To achieve better prognosis. clinicians should initiate anti-infective treatment for children with MRSA infection according to the clinical characteristics of patients and drug sensitivity of the isolates timely and effectively.

Abstract
PURPOSE To systematically review studies investigating health-related quality-of-life (HrQoL) in patients with premature ovarian insufficiency (POI), to examine questionnaires used and to conduct a meta-analysis of control studies with normal ovarian function. METHODS Data sources: PubMed, Embase, Web of science, CNKI, and CQVIP, searched from inception until June 2018. The search strategy was a combination of medical (e.g. POI), subjective (e.g. well-being) and methodological (e.g. questionnaires) keywords. PRISMA guidelines were used to assess outcome data quality/validity by one reviewer, verified by a second reviewer. Risk of bias within studies was evaluated. A meta-analysis compared HrQoL in patients and non-patients. Due to measurement differences in the studies, the effect size was calculated as standard mean difference. RESULTS We identified 6869 HrQoL studies. Nineteen geographically diverse studies met inclusion criteria, dated from 2006, using 23 questionnaires. The meta-analysis included six studies with 645 POI participants (age 33.3 ± 5.47) and 492 normal-ovarian control subjects (age 32.87 ± 5.61). Medium effect sizes were found for lower overall HrQoL (pooled SMD = - 0.73, 95% CI - 0.94, - 0.51; I2 = 54%) and physical function (pooled SMD = - 0.54, 95% CI - 0.69, - 0.39; I2 = 55%). Heterogeneity was investigated. Effect sizes varied for sexual function depending on the measure (SMD = - 0.27 to - 0.74), overall HrQoL (SF-36) had the largest effect size (- 0.93) in one study. The effect sizes for psychological and social HrQoL were small. CONCLUSION POI is associated with low-to-medium effect size on HrQoL compared to normal ovarian controls. The greatest effects are found in general HrQoL and most sexual function areas. Condition-specific questionnaires and RCTs are recommended for further investigation.

Abstract
BACKGROUND Despite advances in asthma management, exacerbations constitute a significant health economic burden. OBJECTIVE To observe the efficacy and safety of Chinese herbal medicine formula entitled PingchuanYiqi (PCYQ) granule, on acute asthma and to explore its possible mechanism. MATERIALS AND METHODS This proof-of-concept study consisted of a randomized, double-blind, placebo-controlled trial in patients with acute asthma (n = 300). Participants with acute mild-to-moderate asthma recruited from seven centers in China were randomly assigned to receive PCYQ or placebo. The primary outcomes were PEF (L/min) and total asthma symptom scores. Furthermore, a panel of cytokines including serum IL-4, IL-5, IL-6, IL-8, IL-1β, IL-17A, IFN-α, IFN-β, IFN-γ, CRP, CCL-5, IP-10, and PGD2 levels was detected using ELISA. RESULTS The PCYQ (n = 139) significantly improved the morning PEF on day 4 (349.73 ± 93.92 vs. 313.56 ± 92.91 L/min, P = 0.004) and day 7 (360.42 ± 94.39 vs. 329.52 ± 95.97 L/min, P = 0.023), and the evening PEF on day 4 (352.65 ± 95.47 vs. 320.58 ± 95.30 L/min, P = 0.012) and day 7 (360.42 ± 94.39 vs. 336.86 ± 95.59 L/min, P = 0.029) in comparison with the placebo (n = 143). The PCYQ also improved the clinical symptoms scores and reduced the puffs of short-acting β2-agonist (all P < 0.05). Furthermore, the PCYQ statistically reduced IL-5, IL-8, IL-1β and PGD2 in serum. CONCLUSION The PCYQ as the Chinese herbal medicine formula significantly improves lung function and symptoms of acute asthma, and reduces SABA dosage possibly via decrease of inflammatory biomarkers such as IL-5, IL-8, IL-1β and PGD2.

Abstract
Objective: To evaluate the feasibility of detecting index of microcirculatory resistance (IMR) and the relationship between IMR and left ventricular (LV) systolic function after acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI). Methods: The patients with first AMI received primary PCI in Peking University Third Hospital were enrolled from January 2014 to March 2016. IMR were measured immediately after PCI by using pressure/temperature wire. The relationship between IMR and left ventricular ejection fraction (LVEF) assessed by echocardiography at first day and 6 months after admission was evaluated. Results: Twenty-eight patients with anterior wall AMI were enrolled, with an average age (56±13) years. The success rate of IMR detection was 100%. The mean IMR was (33±18 )mmHg·s. There was no complication related to intravenous adenosine triphosphate (ATP) (140 μg· kg(-1)· min(-1)). The IMR was negatively correlated with TIMI blood flow grade after primary PCI (r=-0.386, P=0.043), and positively correlated with female gender, CK peak value and TnT peak value (r=0.430, P=0.022; r=0.431, P=0.025; r=0.434, P=0.024). After 6 months of follow-up, no adverse cardiovascular events (including cardiac death, nonfatal myocardial infarction, malignant arrhythmia, unplanned revascularization, hospitalization for unstable angina pectoris and severe heart failure requiring hospitalization) occurred. LVEF increased significantly compared with the first day after PCI (0.54±0.08 vs 0.47±0.06, P=0.001), and IMR was negatively correlated with LVEF after 6 months (r=-0.477, P=0.014). Multivariable linear regression analysis showed that CK peak and IMR were predictors of LVEF after six months ( β=-0.595, t=-3.814, P=0.01; β=-0.352, t=-2.26, P=0.036). Conclusions: Immediate detection of IMR in patients with anterior wall AMI after PCI is safe and feasible. The immediate IMR after PCI reflects the extent of myocardial necrosis and myocardial perfusion, and is a predictor of LVEF at 6 months after PCI.

Abstract
Magnesium, a promising biodegradable metal, has been reported in several studies to increase bone formation. Although there is some information regarding the concentrations of magnesium ions that affect bone remodeling at a cellular level, little is known about the effect of magnesium ions on cell gap junctions. Therefore, this study aimed to systematically investigate the effects of different concentrations of magnesium on bone cells, and further evaluate its effect on gap junctions of osteoblasts. Cultures of normal human osteoblasts were treated with magnesium ions at concentrations of 1, 2 and 3 mM, for 24, 48 and 72 h. The effects of magnesium ions on viability and function of normal human osteoblasts and on gap junction intercellular communication (GJIC) in osteoblasts were investigated. Magnesium ions induced significant (P<0.05) increases in cell viability, alkaline phosphate activity and osteocalcin levels of human osteoblasts. These stimulatory actions were positively associated with the concentration of magnesium and the time of exposure. Furthermore, the GJIC of osteoblasts was significantly promoted by magnesium ions. In conclusion, this study demonstrated that magnesium ions induced the activity of osteoblasts by enhancing GJIC between cells, and influenced bone formation. These findings may contribute to a better understanding of the influence of magnesium on bone remodeling and to the advance of its application in clinical practice.

Abstract
In this study, the association between the 729G/C polymorphism in Toll-like receptor 4 (TLR4) and the risk of bladder cancer was investigated. A total of 376 patients with bladder cancer and 380 healthy volunteers from the Third Xiangya Hospital of Central South University (China) were enrolled in this study between January 2008 and February 2014. The TLR4-729G/C polymorphism was detected by the polymerase chain reaction-restriction fragment length polymorphism assay. There was a significant difference in the distribution of the TLR4-729G/C genotype between bladder cancer patients and healthy controls (P < 0.001). Our analysis showed that the GC genotype (OR = 2.99; 95%CI = 1.01-4.81, P = 0.046) and CC genotype (OR = 3.67; 95%CI = 2.11-7.27, P = 0.017) were significantly associated with increased bladder cancer risk when the GG genotype served as a reference. Furthermore, carriers of the C allele had a significantly increased risk of developing bladder cancer (OR = 3.89; 95%CI = 2.88-8.53; P = 0.009). Our results suggest a correlation between the TLR4-729G/C polymorphism and the risk of developing bladder cancer in this Chinese population.

Abstract
Four oil component-degrading bacteria and one oil-tolerant microalgae, Scenedesmus obliquus GH2, were used to construct an artificial microalgal-bacterial consortium for crude-oil degradation. The bacterial strains included Sphingomonas GY2B and Burkholderia cepacia GS3C, along with a mixed culture, named GP3, containing Pseudomonas GP3A and Pandoraea pnomenusa GP3B. GY2B could only degrade polycyclic aromatic hydrocarbons, GS3C was able to degrade aliphatic chain hydrocarbons, and GP3 could utilize both saturated and aromatic hydrocarbons. In combination with unialgal or axenic algae, the bacteria showed different effects on oil degradation. Unialgal GH2 was not suitable for the consortium construction, as it could not cooperate well with GS3C and GP3. The axenic GH2 exhibited no oil-degrading ability; however, it significantly promoted the degradation ability of the oil component-degrading bacteria, especially for degrading biorefractory polycyclic aromatic hydrocarbons. Axenic S. obliquus GH2, combined with the four bacteria mentioned above, formed an optimal algal-bacterial consortium. The artificial consortium demonstrated an elevated efficiency in degrading both aliphatic and aromatic hydrocarbons of crude oil.

Abstract
OBJECTIVE To study the neurocyte apoptosis and change of cytosolic free calcium induced by hypoxia/hypoglycemia culture in SH-SY5Y human neuroblastoma cells, and the effect of Shenmai Injection (SMI) on them. METHODS The neurocyte apoptosis rate was analysed quantitatively by flow cytometry and cytosolic calcium was determined by measuring mean fluorescent value with Fluo-3 flurometry. RESULTS Hypoxia/hypoglycemia could induce neurocyte apoptosis and increase the cytosolic calcium in SH-SY5Y cells. SMI could inhibit the SH-SY5Y cell apoptosis and lower the concentration of cytosolic free calcium. CONCLUSION Apoptosis is one of the death pattern of nerve cells. SMI could obviously reduce the hypoxia/hypoglycemia induced apoptosis and calcium overload, thus protect the neurocytes.

Abstract
Doxophylline, a new antibronchospastic drug, being more active and less toxic than aminophyline, was detected by high-performance thin layer chromatography. The pharmacokinetics of doxophylline have been characterized in rats, whose serum concentration were monitored after 100, 200, 400 mg.kg-1 oral dose. The drug was found to conform to a one-compartment model and can be bio-transformed quickly in rats. The Cmax, AUC and CL/F appeared to be dose-dependent. T1/2 (Ke) was 1.17 +/- 0.13 h after the 100 mg.kg-1 dose, 2.54 +/- 0.60 h after the 200 mg.kg-1 dose and 3.75 +/- 0.92 h after the 400 mg.kg-1 dose. The doxophylline concentration in tissues decreased rapidly. Total excretion of the drug in urine, bile and faeces was 5.2 per cent of the dose. Plasma protein binding was about 25 percent.

Abstract
Although human exposure generally occurs to mixtures of chemicals, limited toxicological information is available to characterize the potential interactions of the components of environmental mixtures. This study was conducted to compare the genotoxicity of chemically characterized polycyclic aromatic hydrocarbon (PAH) mixtures using in vitro and in vivo techniques. A total of three extracts (E1-E3) were selected from sediment samples collected from a lake adjacent to an abandoned coal gasification site. Sediments were collected on a grid moving downstream and away from the most likely source of PAH contamination, with E1 collected closest to the shore, E2 at an intermediate distance, and E3 furthest from the shore. The sediment samples were extracted in methylene chloride and methanol, dried, and redissolved in an appropriate solvent for evaluation in a battery of genotoxicity assays. Samples were evaluated for their ability to produce point mutations in bacteria and DNA adducts in vitro without metabolic activation or in vivo. Samples were also analyzed using GC/MS. Sample E1 had both the highest concentration of benzo(a)pyrene (BP) (46.5 ppm) and carcinogenic PAHs and, using 32P-postlabeling, induced the highest adduct levels overall in vitro and in vivo. Sample E2, which had a BP concentration of 14 ppm, induced the greatest number of revertants in the bacterial mutagenicity assay. Sample E3, which had the lowest level of carcinogenic PAHs and BP, induced the lowest adduct levels. However, E3 was capable of inducing a positive genotoxic response in bacteria (with S9), although the slope of the response at lower doses was less than that of E2. The in vivo data showed that the major adduct formed by E1 and E2 was a BP adduct. This information could not have been obtained with the Salmonella or in vitro postlabeling tests. Among internal organs, the extracts of all three samples induced the greatest adduct levels in the lung, similarly to previous complex PAH mixtures studied. These data demonstrate the limitations of predicting genotoxic or carcinogenic potential based on chemical analysis or a single biological test. The results suggest that mixture interactions, cytotoxicity and metabolism are likely to have an influence on the potential of a complex mixture of chemicals to produce a carcinogenic effect. In addition, the concentration of genotoxic PAHs and both in vitro and in vivo DNA adduct formations were decreased with increasing distance from the shoreline.

Abstract
We designed a specific primer of EB virus Bam W fragment and EBV DNA sequence by using the polymerase chain reaction (PCR) to amplify the EBV DNA sequences and then performing the hybridization analysis (dot blot and Southern transfer) with a gamma 32P end-labelled internal oligonucleotide probe. There was a significantly higher positive rate of 24% (7/29) for the labial glands of Sjögren's syndrome patients than 68% (20/29) for gamma 32P Bam W probe. In situ DNA hybridization, with (alpha 35S) DCTP labelled EBV DNA probe, the EBV genomes were demonstrated in the labial glands of the Sjögren's syndrome patients (16/28). Moreover, the elevated content of EBV DNA was identified in those with more severe destruction of labial glands. We conclude that EBV has a normal site of latency at salivary glands in a nonpathogenic state, and may be reactivated in Sjögren's syndrome patients and play a role in the pathogenesis of this disease. The great sensitivity of PCR and the ability to analyze very small tissue biopsies (fresh or paraffin-embedded) make this technique applicable to clinical diagnosis.

Abstract
A new analytical method for the separation and determination of seven aqueous depsides in salvia miltiorrhiza by HPTLC has been developed. The seven depsides are protocatechualdehyde, caffeic acid, methyl rosmarinate, rosmarinic acid, salvianolic acid A, B and C. Using chloroform-ethyl acetate-benzene-formic acid(2.4:2:1:0.6) as developing solvent A, protocatechualdehyde was separated; using chloroform-ethyl acetate-benzene-formic acid-methanol (1.5:2:1:1:0.1) as developing solvent B, the other six constituents were well separated. The aqueous depsides were detected at the wave lengths of lambda S = 300 nm and lambda R = 240. This method is simple, rapid, sensitive and accurate. The contents of seven depsides in several Salvia species were determined.

Abstract
In vitro erythropoiesis from fetuses, newborn infants, and adults was compared in methyl cellulose cultures. Fetal and newborn blood erythroid colony formation tended to be more sensitive to erythropoietin than adult. The day of maximal colony formation was earlier in fetal than in newborn or adult cultures. The number of colonies/100,000 mononuclear cells on d 13 of culture and on the day of peak growth was highest in fetal, intermediate in newborn, and lowest in adult cultures. Burst forming units-erythroid/mL of blood on culture d 13 and the day of peak growth were similar in fetuses and newborns, and both were significantly greater than in adults. The proportional synthesis of gamma-globin in fetal colonies was 2-fold greater than in newborn colonies, and 6-fold greater than in adult colonies. Thus, fetal, newborn, and adult erythroid progenitor cultures are each unique with regard to erythropoietin sensitivity, growth time course, number of erythroid colonies, and the proportion of gamma-globin synthesis.

Abstract
It is clear that in vitro hemin increases the number of blood BFU-E derived colonies from normal donors. This occurs with sickle donors as well, despite the increased levels of hemin in vivo in these patients. The effect of hemin on relative gamma globin synthesis is inconsistent, however. In a few cases, delayed addition of hemin led to increased gamma globin synthesis. In time course studies of cultures from normal donors, hemin added on day 0 shifted the day of peak colony number from 13-14 to 16-20 days. The temporal decline in gamma globin synthesis was not altered. In cultures from sickle donors we found that the time for maximal colony number was later than in normals, occurring at 16-20 days even without hemin, and was not further delayed by hemin. The relative proportion of gamma globin synthesis was higher on day 14 in the sickle than the normal cultures, and the temporal decline was somewhat slowed in the sickle cultures by hemin. The elevated gamma synthesis and the later time for peak colony growth in the sickle cultures suggest that the erythroid progenitors in the blood of the sickle patients are less mature than those from normal individuals. There are several possible explanations for the detection of increased numbers of colonies in cultures containing hemin. Hemin may delay the final maturation of erythroblasts within erythroid colonies, thus shifting the time of maximal growth. It may also increase the extent of final maturation, leading to more complete hemoglobinization of the erythroblasts within the colonies, and thus increasing the number of colonies that are eventually recognized as erythroid.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The application of micro HPLC to the determination of amygdalin in Semen pruni armeniacae and Semen pruni persicae is described. Amygdalin is separated at ambient temperature on a reversed phase column of U-Finepak SIL C18(150 x 0.5 mm) with methanol + water (25:75 v/v) as the mobile phase at a flow rate of 10 microL/min. The results are calculated by the internal standard method. The linear range is 1-7 micrograms. The CV and recovery of pure amygdalin are 1.47% (n = 10) and 98.13%, respectively. The results of analysis are lower than those obtained by TLC, but microHPLC is much simpler, faster, and more sensitive and reproducible than TLC.
