Abstract
Cordyceps militaris Link. (C. militaris) is an entomopathogenic fungus that parasitizes the pupa or cocoon of lepidopteran insect larvae, with various bioactive compounds. Cordycepin and ergosterol are the two active components in C. militaris. This study aimed to evaluate the inhibitory activity of cordycepin and ergosterol against xanthine oxidase (XO) and cyclooxygenase-2 (COX-2), as well as investigate the inhibition mechanism. Cordycepin could better inhibit XO (IC50 = 0.014 mg/mL) and COX-2 (IC50 = 0.055 mg/mL) than ergosterol. Additionally, surface hydrophobicity and circular dichroism (CD) spectra results confirmed the conformational changes in enzymes induced by cordycepin and ergosterol. Finally, cordycepin and ergosterol significantly decreased uric acid (UA) and inflammatory factors to normal level in mice with gouty nephropathy (GN). This study could provide theoretical evidence for utilization of C. militaris in hyperuricemia-management functional foods.

Abstract
The data of a patient with carbamate pesticide poisoning were analyzed. Cardiac arrest, oliguria, acute renal injury and pulmonary infection occurred during treatment. After cardiopulmonary resuscitation, tracheal intubation, CRRT, anti-infection and other symptomatic support treatment, the patient recovered and discharged. The myocardial damage caused by carbamate pesticide poisoning is easy to be ignored, and it often causes cardiac manifestations such as arrhythmia and cardiac insufficiency, and the related markers of cardiac injury, electrocardiogram and echocardiogram are also changed. Therefore, the awareness of cardiac damage caused by carbamate pesticide poisoning should be improved.

Abstract
Due to declines in pollinator populations, many people are now interested in learning about which annual flowers they can plant in their garden to better support pollinators. However, reports of experimental evaluation of cultivars of annual flowers for attraction to pollinators are scarce. We sampled pollinators visiting six cultivars of marigold (Tagetes erecta and T. patula), ten cultivars of bidens (Bidens ferulifolia and B. aurea), and eight cultivars of portulaca (Portulaca oleracea and P. grandiflora) for two years to compare pollinator visitation rates among cultivars within each flower type. Pollinators collected on flowers in research plots were categorized into four groups, honey bees (Apis mellifera), common eastern bumble bees (Bombus impatiens), wild bees, and syrphids, to show the proportion of different pollinator visitors to each cultivar. Pollinator visitation rates varied significantly among cultivars of marigold, bidens, and portulaca, with some cultivars having as much as 10-fold the visitation rate of other cultivars of the same flower type. In the second year we also evaluated nectar production and nectar quality of the most and least visited cultivars of portulaca and bidens. Our results show that pollinators have a strong preference for cultivars that produce the most nectar or nectar with the highest sugar content. This research will better inform entomologists, growers, educators, and plant breeders, about which cultivars of marigold, portulaca, and bidens are visited the most by pollinators, and how to accurately determine this at the cultivar level.

Abstract
Objective: To analyze the direct economic burden caused by measles cases in Shanghai from 2017 to 2019 and its influencing factors. Methods: A total of 161 laboratory-confirmed measles cases reported from January 1, 2017, to December 31, 2019, in Shanghai were included in the study through the "Measles Surveillance Information Reporting and Management System" of the "China Disease Surveillance Information Reporting and Management System". Through telephone follow-up and consulting hospital data, the basic information of population, medical treatment situation, medical treatment costs and other information were collected, and the direct economic burden of cases was calculated, including registration fees, examination fees, hospitalization fees, medical fees and other disease treatment expenses, as well as transportation and other expenses of cases. The multiple linear regression model was used to analyze the main influencing factors of the direct economic burden. Results: The age of 161 measles cases M (Q1, Q3) was 28.21 (13.33, 37.00) years. Male cases (56.52%) were more than female cases (43.48%). The largest number of cases was≥18 years old (70.81%). The total direct economic burden of 161 measles cases was 540 851.14 yuan, and the per capita direct economic burden was 3 359.32 yuan. The direct economic burden M (Q1, Q3) was 873.00 (245.01, 4 014.79) yuan per person. The results of multiple linear regression model analysis showed that compared with other and unknown occupations, central areas and non-hospitalized cases, the direct economic burden of measles cases was higher in scattered children, childcare children, students, and cadre staff in the occupational distribution, suburban areas and hospitalized, with the coefficient of β (95%CI) values of 0.388 (0.150-0.627), 0.297 (0.025-0.569), 0.327 (0.148-0.506) and 1.031 (0.853-1.209), respectively (all P values<0.05). Conclusion: The direct economic burden of some measles cases in Shanghai is relatively high. Occupation, area of residence and hospitalization are the main factors influencing the direct economic burden of measles cases.

Abstract
Objective: To investigate the mid-term clinical outcome of deep layer repair with the long head of the biceps autograft bridging for Kim classification type ⅠA delaminated rotator cuff tear. Methods: A follow-up study. The clinical data of 42 consecutive patients with Kim classification type ⅠA delaminated rotator cuff tear admitted to the First Affiliated Hospital of Jinan University from January 2018 to June 2019 were retrospectively included. All patients underwent shoulder arthroscopic surgery. During the operation, the autogenous long head of the biceps tendon was transferred to repair the deep layer of delaminated rotator cuff tear. The preoperative and postoperative (last follow-up) visual analogue scale (VAS) for pain, University of California Los Angeles (UCLA) score, Constant-Murley shoulder score, range of motion (ROM) of the shoulder and radiographic results were statistically analyzed. Results: A total of 42 patients were included in this study. There were 18 males and 24 females, with an average age of (64.5±15.2) years and a mean follow-up of (43.9±7.1) months. At the last follow-up, ROM of abduction increased from 80.8°±26.5° to 154.2°±14.3°, and ROM of external rotation increased from 18.2°±13.6° to 31.8°±7.8°; the VAS score of pain decreased from (5.5±1.3) points to (0.7±0.7) points, the UCLA score increased from (21.3±3.7) points to (29.9±2.1) points, and the Constant-Murley score increased from (45.4±10.0) points to (87.2±4.8) points; the differences were all statistically significant (all P<0.001). The X-ray films showed that there were no upward of the humeral head in all the patients. MRI results indicated that rotator cuff re-teared in one case (Sugaya classification type Ⅲ), and healed in other cases (Sugaya classification type Ⅰ-Ⅱ). No complications such as upper limb nerve injury was found in all cases. Conclusion: Deep layer repair with the long head of the biceps autograft bridging can significantly alleviate the pain and improve the function of patients with Kim classification type ⅠA delaminated rotator cuff tear, and the incidence of retear is low.

Abstract
Objective: To examine the prevalence and trend of tobacco and e-cigarettes uses and identify the influencing factors for smoking behavior in junior middle school students in Shanghai, and provide data support and scientific basis for the development of tobacco control intervention strategy in adolescents. Methods: Multi-stage stratified random sampling method was used to select junior middle school students in 8 districts and 10 districts in Shanghai in 2013 and in 2019 respectively. Information about tobacco and e-cigarettes uses in the students were collected by using self-administrated questionnaire. The prevalence of tobacco and e-cigarettes uses were calculated, the difference between two years was compared with χ2 test. The influencing factors were identified by multivariate logistic regression analysis. Results: In 2019, the current smoking rate was 0.6% in junior middle school students in Shanghai, and the smoking attempt rate was 2.9%, both were lower than the levels in 2013 (0.7% and 6.9%). The current use rate of e-cigarettes was 0.6% in 2019,with no significant change compared with 2013 (0.6%). The proportion of the students who had heard of e-cigarettes in 2019 (78.4%) was higher than that in 2013 (47.2%). In 2019, the second-hand smoke (SHS) exposure rate at home, in both indoor and outdoor public places and on public transportations was 72.5%, which was slightly lower than the level in 2013 (73.0%), the differences were all significant (P<0.05). In 2019, the students seeing close friend smoking (OR=27.381, 95%CI: 12.037-62.287), seeing someone smoking in school (OR=2.477, 95%CI: 1.155-5.312), believing that SHS may not be harmful (OR=8.471, 95%CI: 1.464-49.005) had higher possibility of smoking. Being aged ≥15 years (compared with being aged ≤12 years, OR=8.688, 95%CI: 1.922-39.266), exposure to SHS in outdoor public place (OR=8.608, 95%CI: 1.048-70.692), close friend smoking (OR=8.115, 95%CI: 1.754-37.545) were positively associated with e-cigarettes use, and believing that smoking results in uncomfortable social contact [compared with believing that smoking results in comfortable social contact (OR=0.105,95%CI: 0.018-0.615)] were negatively associated with e-cigarettes use, the difference was significant (P<0.05). Conclusion: The prevalence of tobacco and e-cigarette uses in junior middle school students in Shanghai remained at a low level in recent years. The SHS exposure rate in junior middle school students is high. Smoking behavior of junior middle school students is closely related to personal attitude and awareness of tobacco, exposure to SHS, peer smoking and the situation of tobacco control in schools. Prevention and intervention should be carried out from multi-dimensions to effectively protect teenagers from tobacco hazards.

Abstract
Influenza is an infectious respiratory disease caused by the influenza viruses. Older people, infants and people with underlying medical conditions could have a higher risk of severe influenza symptoms and complications. The co-infection of Coronavirus Diseases 2019 (COVID-19) with influenza viruses could lead to the complication of prevention, diagnosis, control, treatment, and recovery of COVID-19. Influenza vaccine and COVID-19 vaccine overlapped in target populations, vaccination time, and inoculation units. Although there was insufficient evidence on the immunogenicity and safety of co-administration of influenza vaccine and COVID-19 vaccine, World Health Organization and some countries recommended co-administration of inactivated influenza vaccine and COVID-19 vaccine. This review summarized domestic and international vaccination policies and research progress, and put forward corresponding suggestions in order to provide scientific support for the formulation of vaccination strategy on seasonal influenza vaccine and COVID-19 vaccine.

Abstract
Proportion and rate have multiple and overlapping meanings, which blur their concepts. Based on the existence of the states and the occurrence of the events and their measuring process, we first put forward the concept of "cumulative number of states in point time". Considering the general meaning of "rate" in mathematics and the units of the elements in indexes, this paper puts forward the concept of "the change of cumulative number of states in point time", which is equal to the commonly acknowledged concept "number of incident event within observation period" or "absolute rate", and further constructs relative rate and proportion. Proportions can be classified into three types: time-point (or rate-type) constitutional proportion, time-period incidence proportion and their synthesis, time-period constitutional proportion. The essential difference between relative rate and time-period proportions is whether the observation period is regarded as a one-unit-length fixed period which would be further moved to the description of the indexes. Furthermore, the sources populations of relative rate and proportions are exclusively those at the beginning of the observation period. Thus, we established a unified identification route about ratios, proportions, and rates, the basic indicators of categorical data in populations. These are applicable to both fixed and dynamic populations. The paper aims to clarify the connotation of the indexes and the feasible understanding route and provide some reference for the population researchers.

Abstract
Since the Global Polio Eradication Initiative was launched by the World Health Assembly in 1988, significant progress has been made in global polio prevention and control. But the occurrence of vaccine-associated paralytic poliomyelitis cases and vaccine-derived poliovirus related cases have become a major challenge during the post-polio era. While coronavirus disease 2019(COVID-19) has brought serious disease burden and economic burden to all countries in the world, prevention and control of vaccine-preventable infectious diseases such as polio should not be neglected under the background of the global common fight against COVID-19. Taking the type Ⅲ VDPV cycle event in Shanghai as an example, the paper discussed how to do a good job of routine inoculation under the prevention and control of COVID-19 to strictly prevent the outbreak of vaccine-preventable infectious diseases.

Abstract
Objective: To evaluate the efficacy of 23 valent pneumococcal polysaccharide vaccine (PPV23) inoculation against community-acquired pneumonia (CAP) among the elderly aged 60 years old and above in Shanghai. Methods: A prospective cohort study was conducted using a stratified random sampling from October 2013, in which 1 214 and 2 387 elderly people aged 60 and above were selected as the inoculation group and control group, respectively. And a unified questionnaire was used to investigate the basic information of the subjects in the inoculation group and the control group. From October 2013 to December 2018, the subjects were followed up at home or by telephone for a total of 20 times, mainly for whether they had CAP during the observation period. Multivariate logistic regression model was used to calculate RR and 95%CI of CAP incidence between inoculation group and control group for comparing. Results: There were 556 males (45.8%) in the inoculation group and 1 012 males (42.4%) in the control group. And the incidence density of CAP in the inoculation group was lower than that of the control group (0.848/100 person-years vs. 1.452/100 person-years), and the vaccine protection rate was 41.6%, with a statistically significant difference [RR (95%CI)= 0.584 (0.428-0.790), P<0.001]. After adjusting for age, RR (95%CI) was 0.699 (0.507-0.956), and the difference was still statistically significant (P=0.025).Further stratified analysis showed that the vaccine protective rates of PPV23 in the 60-69 year-old group, the 70-79 year-old group and the ≥80 year-old group were 36.7%, 21.6% and 26.0%, respectively, but only in the 60-69 year-old group showed statistical difference (RR=0.633, 95%CI=0.399-0.990, P=0.045). Conclusion: To a certain extent, the incidence of CAP can be reduced by inoculation of PPV23 in elderly population aged 60 and above in Shanghai, and it should be further recommended in elderly population of low age.

Abstract
Accurate and fast characterization of spatio-temporal information of high-intensity, ultrashort pulses is crucial in the field of strong-field laser science and technology. While conventional self-referenced interferometers were widely used to retrieve the spatial profile of the relative spectral phase of pulses, additional measurements of temporal and spectral information at a particular position of the laser beam, however, were necessary to remove the indeterminacy, which increases the system complexity. Here we report an advanced, dual-functional interferometer that is able to reconstruct the complete spatio-temporal information of ultrashort pulses with a single scan of the interferometer arm. The setup integrates an interferometric frequency-resolved optical gating (FROG) with a radial shearing Michelson interferometer. Through scanning one arm of the interferometer, both the cross-correlated FROG trace at the central part of the laser beam and the delay-dependent interferograms of the entire laser profile are simultaneously obtained, allowing a fast three-dimensional reconstruction of few-cycle laser pulses.

Abstract
Poly(vinylidene difluoride) (PVDF) and its copolymers as the polymers with the highest piezoelectric coefficient have been widely used as sensors and generators. However, their relatively low performances limit their applications in some harsh environments. In this work, piezoelectric poly(vinylidene-trifluoroethylene) P(VDF-TrFE) matrices with different amounts of polyhedral oligomeric silsesquioxane (POSS) were prepared by a low temperature solvent evaporation method and thermal poling. The morphology, surface performance, crystalline phase, and piezoelectric and ferroelectric properties of the nanocomposites were investigated and the influence of POSS on these performances was studied. POSS had good compatibility with P(VDF-TrFE) and did not affect the crystalline phase formation of the matrix. The composites presented good piezoelectric properties. Piezo- and triboelectric nanogenerators were designed and fabricated. The voltage and current outputs were analyzed and the polarization effect was evaluated. The average output voltage and the current density of the matrix were 3 V and 0.5 μA cm−2 when subjected to a force of 38 N on an area of 1 cm2. The mechanical properties of P(VDF-TrFE)/POSS nanocomposites were also studied by the nanoindentation test. The hardness and modulus of samples increased 20% and 17% with a low addition of POSS. Atomic oxygen erosion properties of the composites were numerically simulated by the Monte Carlo method. The erosion cavity shape and depth were compared and studied. The influence of POSS addition on the P(VDF-TrFE) matrix and the associated reinforcing mechanism were analyzed. Poly(vinylidene difluoride) (PVDF) and its copolymers as the polymers with the highest piezoelectric coefficient have been widely used as sensors and generators.![]()

Abstract
We investigate in the experiments the ionization-induced adiabatic soliton compression process in a short length of He-filled single-ring photonic crystal fiber. We observe that the plasma-driven blueshifting solitons show little residual light near the pump wavelength in a certain pulse energy region, leading to a high-efficiency frequency upconversion process. In contrast, at high pulse energy levels, we observe that the quality of the frequency upshifting process is impaired due to the existence of a dynamical loss channel induced by the coupling of the soliton to linear modes near the pump wavelength. In addition, through adjusting the input pulse energy, the central wavelength of blueshifting solitons can be continuously tuned over 300 nm. These experimental results, confirmed by numerical simulations, not only offer a deep insight into ionization-induced soliton-plasma dynamics in gas-filled hollow-core photonic crystal fibers, but also develop highly tunable ultrafast light sources at visible wavelengths, which may have many applications in ultrafast spectroscopy.

Abstract
Abstract
Background
Poor cell homing limits efficacy of cardiac cellular therapy. The cysteine–arginine–glutamic acid–lysine–alanine (CREKA) homing peptide binds with high specificity to fibrin which is involved in repair of tissue injury.
Purpose
We assessed if CREKA-modified stem cells had enhanced fibrin-mediated homing ability resulting in better functional recovery and structural preservation in a rat myocardial injury model.
Methods
CREKA-modified mesenchymal stem cells (CREKA-MSCs) were obtained via membrane fusion with CREKA-modified liposomes. The fibrin targeting ability of CREKA-MSCs was examined both in vitro and in vivo.
Results
Under both static and flow conditions in vitro, CREKA significantly enhanced MSCs binding ability to fibrin clots. CREKA-MSCs showed much more higher accumulation than unmodified MSCs in injured rat myocardium, colocalizing with fibrin and resulting in better cardiac function.
Stem cell-CREKA-fibrin targeting system
Conclusions
Modification of MSCs with the homing peptide CREKA favored their migration and retention in the infarcted area, resulting in better structural preservation and functional recovery. Fibrin is therefore a novel target for enhancing homing of transplanted cells to injured myocardium and the fibrin-targeting delivery system represents a generalizable platform technology for regenerative medicine.

Abstract
Objective: To explore the clinical features and genetic causes of autism spectrum disorder (ASD) patients with epilepsy. Methods: The clinical data of five patients with ASD and epilepsy admitted to Xuanwu Hospital between September 2017 and September 2018 were collected, including medical history, intelligence level, developmental level, physical examination, neuroimaging and electroencephalogram. High-throughput whole-genome sequencing was applied to five patients and their parents. Results: Of five patients, four were male and one was female. All five patients had mild mental retardation, and one patient had significant growth retardation and craniofacial deformity. The average epilepsy onset age was 6.3 years old (7 months to 16 years). The main epileptic type was tonic-clonic seizure with abnormal EEG results. All patients have a favorable response to anti-epileptic drugs. Whole-exome sequencing (WES) revealed copy number variation in all 5 patients. Among them, 3 cases were reported to be pathogenic, and 2 cases were not reported (chromosome 16p13.3 duplication and chromosome 21q22.3 deletion). Conclusions: The results of current study support that autism spectrum disorders with seizures is often associated with copy number variations, such as Williams-Beuren region duplication syndrome, chromosome 15q11.2 duplication syndrome and chromosome 15q11.2 deletion syndrome. We reported two novel copy number variations (chromosome 16p13.3 duplication and chromosome 21q22.3 deletion) in two autism spectrum disorder patients with epileptic seizures.

Abstract
Liver resection is the mainstay of treatment for patients with hepatocellular carcinoma (HCC). Most of HCC patients are associated with varied degrees of liver cirrhosis.Severity of liver cirrhosis adversely affects the outcomes of liver resection, and also plays a vital role in making an appropriate surgical strategy for HCC.In current surgical practice for HCC, liver function and functional reserve are the focus of preoperative evaluation. Liver cirrhosis is still widely regarded as an one-stage entity. The pathological severity of liver cirrhosis is largely ignored. As neither liver function nor functional reserve can reflect the pathological severity of liver cirrhosis when liver function is at the stage of compensation. Preoperative evaluation on the severity of cirrhosis has not been established in a surgical setting.Thus, there is an urgent need to stage the severity of cirrhosis in surgical practice in order to make more precise surgical modalities for individual patients.This article mainly introduces the ongoing research progress in staging the severity of liver cirrhosis while treating HCC at Hepatic Surgery Center, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, and emphasizes the importance of staging the severity of cirrhosis in surgical treatment of HCC.

Abstract
Objective: To evaluate the safety of population based sequential vaccination schedule of inactivated poliovirus vaccines prepared with different strains. Methods: This randomized, parallel-group controlled trial was conducted from March, 2017 to May, 2018, in Shanghai. Adverse reaction data of Sabin strain inactivated polio vaccine (sIPV), wild strains inactivated polio vaccines (wIPV) and bivalent types Ⅰ and Ⅲ oral poliomyelitis vaccine (bOPV) were systematically collected through active observation in 1 917 infants in Shanghai after the vaccination at 2, 3, 4 months old. The eligible infants aged 2 months were divided into 4 groups: ①sIPV+sIPV+bOPV group; ②sIPV+wIPV+bOPV group; ③wIPV+sIPV+bOPV group; ④wIPV+wIPV+bOPV group. Results: The incidence of adverse reaction 30 days later after 3 basic dose vaccinations was 16.79% (946/5 633). No serious adverse reaction was reported. Local and systemic reactions were mainly mild. Common local reactions were pain, erythema, cutaneous nodule, etc.; and common systemic reactions were abnormal crying, drowsiness, diarrhea and appetite lost, etc.. The incidence of local reactions 30 days later after 3 basic dose vaccinations was 1.65% (93/5 633), and the incidence rates of grade 1-3 reactions were1.26% (71/5 633), 0.21% (12/5 633) and 0.20% (11/5 633) respectively. The incidence rate of systemic reactions 30 days later after 3 basic vaccinations was 15.14% (853/5 633), and the incidence rates of grade 1-3 reactions were 11.33% (638/5 633), 3.18% (179/5 633) and 0.64% (36/5 633) respectively. There were no significant differences in the rate of grade 3 reaction among different groups (χ(2)=4.17, P=0.24). Conclusions: No severe adverse reactions related to sequential vaccination of different strain inactivated polio vaccines were observed, most of reactions were mild and all of them were cured. It is safe to use sIPV and wIPV simultaneously or alternately for childhood sequential vaccination.

Abstract
We experimentally report the generation of wavelength-tunable blueshifting soliton in the visible spectral region through a gas-filled single-ring photonic crystal fiber (SR-PCF). In particular, in a He-filled SR-PCF, we observed a sharp narrow-band spectral peak at the first resonant spectral region of the SR-PCF, which results from phase-matched nonlinear processes. To the best of our knowledge, this is the first time investigating the influence of the core-cladding resonance on the blueshifting soliton. In addition, when Ar gas was filled into the SR-PCF, some interference fringes on the blueshifting soliton were observed at high pulse-energy levels due to plasma-induced pulse fission. These two experimental observations are confirmed by numerical simulations. Furthermore, through properly adjusting input pulse energy, we found that the blueshifting soliton can obtain a high conversion efficiency (∼84%) and its wavelength can be tuned over hundreds of nanometers (∼240 nm).

Abstract
BACKGROUND Knowledge regarding genetic influences on eating behaviours is expanding; yet less is known regarding contributions of epigenetic variation to appetitive traits and body mass index (BMI) in children. OBJECTIVE The purpose of this study was to explore relationships between methylation at differentially methylated regions (DMRs) of imprinted genes (insulin-like growth factor 2/H19 and Delta-like, Drosophila, homolog 1/maternally expressed gene 3) using DNA extracted from umbilical cord blood leucocytes, two genetically influenced appetitive traits (food responsiveness and satiety responsiveness) and BMI. METHODS Data were obtained from participants (N = 317; mean age = 3.6 years; SD = 1.8 years) from the Newborn Epigenetic STudy. Conditional process models were implemented to investigate the associations between DMRs of imprinted genes and BMI, and test whether this association was mediated by appetitive traits and birthweight and moderated by sex. RESULTS Appetitive traits and birthweight did not mediate the relationship between methylation at DMRs. Increased insulin-like growth factor 2 DMR methylation was associated with higher satiety responsiveness. Higher satiety responsiveness was associated with lower BMI. Associations between methylation at DMRs, appetitive traits and BMI differed by sex. CONCLUSIONS This is one of the first studies to demonstrate associations between epigenetic variation established prior to birth with appetitive traits and BMI in children, providing support for the need to uncover genetic and epigenetic mechanisms for appetitive traits predisposing some individuals to obesity.

Abstract
BACKGROUND Slow freezing has been widely applied to preserve human ovarian tissue. OBJECTIVE The aim of this study is to determine whether human ovarian cortex pretreated with hyaluronidase can improve the protective effect of cryopreservation. MATERIALS AND METHODS Human ovarian biopsies from seven patients were cryopreserved using slow freezing. The samples in the experimental group were incubated in culture medium with hyaluronidase for a short time before cryopreservation. The histology of the thawed ovarian tissue was investigated; the levels of steroid hormone in the culture media were then used to evaluate the development and function of thawed ovarian tissue. RESULTS The result showed that the percentage of morphologically abnormal primordial follicles was higher in the freezing control than in the experimental group (P<0.05). 17β-estradiol (E2) and progesterone (P4) concentrations were significantly higher in the experimental group than in the freezing control group (P<0.05). CONCLUSION Our study showed that human ovarian cortex pretreatment with hyaluronidase can improve the protective effect of cryopreservation by improving the penetration of cryoprotectant.

Abstract
Influence of the surface characteristics of three stainless steels (SS304, 316L and 317) and presence of scale inhibitors on adhesion kinetics of sulfate reducing bacteria (SRB) in circulating cooling water, were investigated by evaluating surface free energy, adhesion kinetic constants in a parallel plate flow chamber. Results show that the surface free energy values of SS317, SS316L and SS304 are -31.69, -24.18 and -13.92 mJ m-2, respectively. SS317 surface had higher surface hydrophobicity than SS316L and SS304. In the process of bacteria cells adhesion onto SS surfaces, electrostatic interaction for SS is slightly more than hydrophobic interaction. The number of adhering bacteria and the adhesion kinetic constants are different on the three types of stainless steel. The adhesion kinetic constants for SS317 and 316L are greater than that for SS304, which are 0.0354, 0.0282 and 0.0190 min-1, respectively. Scale inhibitors of hydrosy ethyl fork phosphonic acid (HEDP) and phosphono butane-1, 2, 4-tricarboxylic acid (PBTCA) have a certain influence on the initial adhesion of bacteria cell and adhesion kinetics constants are reduced in the presence of HEDP and PBTCA.

Abstract
By expanding the contactless conductivity detection (CCD) technique to contactless impedance detection technique, a new contactless impedance sensor is designed to implement the online measurement for both the conductivity of a conductive fluid and the permittivity of a non-conductive fluid. In the new contactless impedance sensor, a new simulated inductor is developed to overcome the unfavorable influences of the coupling capacitances by impedance elimination principle, and the digital phase-sensitive demodulation (DPSD) technique is adopted to realize the impedance measurement. To verify the effectiveness of the new contactless impedance sensor, simulation experiments (using different resistors, capacitors, and their combinations) and practical fluid experiments (using KCl solutions with different concentrations, eight organic solvents, and pure water) are carried out. The experimental results show that the development of the new contactless impedance sensor is successful and the conductivity/permittivity measurement performance of the new sensor is satisfactory. The maximum relative error of conductivity measurement is 3.1% and the maximum relative error of permittivity measurement is 5.5%. Compared with the conventional conductivity/permittivity sensors, the new sensor can implement the contactless online measurement of both the two electrical parameters of fluid. Meanwhile, the new contactless impedance sensor is suitable for industrial applications and has the advantages of simple construction and low cost.

Abstract
The results of previous epidemiological studies exploring the relationship between interleukin-10 (IL-10) promoter polymorphisms and susceptibility to pediatric asthma are not consistent. Therefore, we have performed a systematic review and meta-analysis to provide a more convincing conclusion. Odds ratios (OR) with their 95% confidence intervals (CIs) were used to evaluate the strength of association between the IL-10 promoter polymorphisms and susceptibility to pediatric asthma. Publication bias was examined by Begg's funnel plots and the Egger test. A detailed literature search based on stringent parameters yielded sixteen relevant studies, comprising 2494 cases and 2160 controls. The overall population showed no significant association between the IL-10 -1082G/A polymorphism and pediatric asthma risk in any of the genetic models (dominant model: OR = 1.583, 95%CI = 0.614-4.076, P = 0.342; allelic model: OR = 1.214, 95%CI = 0.748-1.971, P = 0.433; additive model: OR = 2.240, 95%CI = 0.950-5.277, P = 0.065; recessive model: OR = 1.435, 95%CI = 0.659-3.128, P = 0.363). Subgroup analyses revealed a significant association between different ethnicity and atopic status subgroups. However, there was no evidence of a significant association between the other two polymorphisms (-819C/ T and -592C/A) and pediatric asthma in our study. No significant publication bias was observed in this meta-analysis. The results of this study indicate that the IL-10 -1082G/A polymorphism might be a risk factor for asthma in children. However, because of the small sample size included in the subgroup analyses, the results should be interpreted with caution.

Abstract
OBJECTIVE To study the characteristics and prevention and treatment strategies of massive hemorrhage caused by fungal infections after donation-after-cardiac-death (DCD) kidney transplantation. METHODS A total of 91 cases of DCD kidney transplantation between August 25, 2013 and June 30, 2015 in Third Affiliated Hospital of Sun Yat-sen Univservity were retrospectively analyzed. The characteristics of and prevention and treatments strategies for postoperative massive hemorrhage caused by fungal infections were summarized. RESULTS Ninety-one cases of DCD kidney transplantation were divided into 2 groups based on regimens for preventing postoperative fungal infections: fluconazole prophylaxis group: a total of 26 cases of renal transplant before June 11, 2014 received fluconazole regimen, from postoperative day 0 to 2 weeks; micafungin prophylaxis group: a total of 65 cases of renal transplant after June 11, 2014 received micafungin regimen, also for 2 weeks from postoperative day 0. Two cases in fluconazole group developed postoperative massive hemorrhage. In case 1, the hemorrhage occurred at 2 weeks after transplantation. Graft nephrectomy was performed during surgical exploration for hemostasis, yet the massive hemorrhage relapsed 2 weeks later. Endoluminal exclusion of external iliac artery using endovascular covered stent-graft at the anastomosis site was performed and the massive bleeding was successfully stopped. The patient was restored to hemodialysis and waited for second kidney transplantation. Candia albicans was detected in the culture of blood and drainage liquid from incision. The other case of hemorrhage occurred at 3 weeks after transplantation. Graft nephrectomy plus endovascular exclusion using covered stent-graft were also performed to stop the massive bleeding. Massive fungal hyphae and spores were observed at the stump of renal graft artery under microscope. The patient received second kidney transplantation after 6 months successfully. No massive hemorrhage caused by fungal infections occurred in micafungin prophylaxis group. CONCLUSIONS Massive hemorrhage cased by fungal infections after DCD kidney transplantation is usually characterized by delayed and recurrent course, and may result in graft nephrectomy or even death of patients. Endovascular exclusion using covered stent can successfully stop bleeding and rescue life of patients. Two-week preemptive prophylaxis of fungal infections using micafungin can effectively prevent delayed fungal massive hemorrhage in DCD kidney transplantation.

Abstract
Varroa destructor (Vd) is a honeybee ectoparasite. Its original host is the Asian honeybee, Apis cerana, but it has also become a severe, global threat to the European honeybee, Apis mellifera. Previous studies have shown that Varroa can mimic a host's cuticular hydrocarbons (HC), enabling the parasite to escape the hygienic behaviour of the host honeybees. By transferring mites between the two honeybee species, we further demonstrate that Vd is able to mimic the cuticular HC of a novel host species when artificially transferred to this new host. Mites originally from A. cerana are more efficient than mites from A. mellifera in mimicking HC of both A. cerana and A. mellifera. This remarkable adaptability may explain their relatively recent host-shift from A. cerana to A. mellifera.

Abstract
The IL-4R Q576R polymorphism has been reported to increase susceptibility to asthma, but the results are controversial. Thus, we performed a meta-analysis to evaluate the association of the IL-4R Q576R polymorphism and asthma risk in the Chinese Han population. A total of sixteen eligible case-control studies that evaluated the relationship between the IL-4R Q576R polymorphism and asthma in the Chinese Han population were obtained by comprehensive literature search incorporating electronic databases, and included 2077 asthma cases and 1589 controls. Our analysis detected a significant association between the IL-4R Q576R polymorphism and the risk of asthma in the Chinese Han population (Allelic model: OR = 1.481, 95%CI = 1.134-1.935, P = 0.004; Dominant model: OR = 1.542, 95%CI = 1.194-1.990, P = 0.001; Recessive model: OR = 1.695, 95%CI = 1.170-2.456, P = 0.005, Additive model: OR = 1.897, 95%CI = 1.299-2.771, P = 0.005). The year of publication and size of total sample might be sources of between-study heterogeneity. Upon subgroup analysis by size of total sample of each study, the significant association only remained in a subgroup with a small sample size. In summary, our meta-analysis suggested that the IL-4R Q576R polymorphism is associated with asthma in the Chinese Han population.

Abstract
UNLABELLED The aim of this study was to determine the response of advanced-stage non-small cell lung cancer (NSCLC) patients with or without EGFR mutations to platinum-based chemotherapy with or without gefitinib maintenance. Patients were treated with four cycles of platinum-based chemotherapy. Patients with wild-type EGFR were observed (group 1; n=15). EGFR mutation-positive patients were randomly assigned to observation (group 2; n=7) or gefitinib maintenance (group 3; n=7). The median patient age was 59 years. The 1-year progression-free survival rates in groups 1, 2, and 3 were 6.7%, 28.6%, and 57.1%, respectively (p = 0.049); the 1-year overall survival rates were 53.3%, 57.1 %, and 100%, respectively (p = 0.111). The results indicate that patients with advanced-stage NSCLC with EGFR mutations have a better response to chemotherapy followed by gefitinib than chemotherapy alone and a better response to chemotherapy than wild-type patients.

Abstract
This study investigated 5 single nucleotide polymorphism (SNP) haplotypes in susceptibility genes for coronary artery disease (CAD) and the putative involvement of these SNPs in CAD in the Chi-nese Han population. From March 2008 to June 2009, we selected 119 CAD patients and 115 subjects not related to the CAD of Chinese Han or-igin as controls. The SNP genotypes were performed by multiplex SNaP-shot technology. The HNRPUL1 gene rs11881940T and GATA2 gene rs3803T loci were highly correlated with CAD (P < 0.05). rs10757278G increased the risk of CAD in patients indicated by an odds ratio (OR) = 1.242 [95% confidence interval (CI) = 1.04-1.49]; rs11881940T and rs3803T were protective factors for CAD with ORs = 0.767 (95%CI = 0.61-0.97) and 0.53 (95%CI = 0.40-0.72), respectively. Analysis of the rs10757278, rs11881940 and rs3803 loci showed that haplotypes ATC (OR = 4.26; 95%CI = 2.85-6.40, P < 0.01), GAC (OR = 1.50; 95%CI = 1.25-1.81, P < 0.01) and GAT (OR = 1.53; 95%CI = 1.12-2.09, P < 0.01) were CAD risk factors, whereas GTC was protective (OR = 0.48; 95%CI = 0.32-0.72, P < 0.01). ATC and glucose were positively correlated (OR = 1.91; 95%CI = 1.01-3.61, P < 0.05). GAT was a risk factor for hyper-tension (OR = 2.86; 95%CI = 1.40-5.83, P < 0.01). In conclusion, poly-morphisms and haplotype analysis of susceptibility genes for CAD can improve predicting this disease and will enable early diagnosis of CAD.

Abstract
Mycoplasma mycoides subsp capri is the cause of goat "MAKePS" (Mastitis, Arthritis, Keratoconjunctivitis, Pneumonia, Septicemia) syndrome. We identified three genes (GL_ 000459; 000461; 000462) as variable lipoprotein genes in the M. mycoides subsp capri str. PG3 genome by genomic information and comparative genomic analyses. To study the role of variable lipoproteins in M. mycoides subsp capri pathogenesis and evaluate the immunogenic and protective potentials of those proteins, we constructed the expression systems and expressed the mature peptide portion of the three proteins in E. coli. We also determined the titers and opsonophagocytosis activity of total IgG antibodies and the levels of Th1 and Th2 cytokines in sera, and we ran a lymphocyte proliferation assay in mice immunized with recombinant proteins His-tag-GL000459, His-tag-GL000461, and His-tag-GL000462. These three lipoproteins induced humoral and cellular immune responses in the immunized mice. Additionally, the whole blood opsonophagocitic in vitro assay demonstrated that the antibodies produced by the immunized groups can neutralize strain PG3; consequently, these three variable lipoproteins could be the major surface antigens in M. mycoides subsp capri str. PG3.

Abstract
A growing body of evidence suggests that the 584C/T polymorphism in the endothelial lipase (EL) gene contributes to the process of coronary artery disease (CAD). The present study aimed to reveal the potential relationship between the EL 584C/T gene polymorphism and early-onset CAD, CAD severity, and lipid levels in a Chinese Han population. Participants comprised 135 early-onset CAD patients and 166 controls. EL 584C/T genotypic and allelic frequencies were detected by PCR. The frequencies of the CC, CT, and TT genotypes were 58.4, 38.6, and 3.0%, respectively, within the control group, and 62.2, 33.3, and 4.5%, respectively, in the early-onset CAD group. There was no significant difference in the frequency of CC genotype and T allele carriers between early-onset CAD patients and controls. The frequency of the T allele was 22.3% in the control group and 21.1% in the early-onset CAD group. The T allele frequency of the variant was not significantly different between the two groups (P = 0.766), even after adjustments for age, gender, smoking status, hypertension, DM, and lipids were made. There was also no significant association between the genotype and the severity of CAD (P = 0.596). Furthermore, there was no correlation between the genotype and lipid levels or their ratios in both groups. The EL 584C/T gene polymorphism, therefore, was not associated with early-onset CAD or the severity of CAD in this Chinese Han population, suggesting that this variant is not always involved in the pathogenesis of early-onset CAD.

Abstract
BACKGROUND Ultraviolet (UV) irradiation is the main cause of skin photodamage; the resulting modulation of matrix metalloproteinases (MMPs) leads to collagen degradation. There is no easily accessible molecular indicator of early skin UV damage. OBJECTIVES In this study, we investigated the effects of Syk kinase on MMP expression and evaluated the sensitivity and usefulness of Syk as an early indicator of skin UV damage. METHODS Human dermal fibroblasts (HDFs) were transfected with Syk cDNA to overexpress Syk. MMP-1 expression and Syk activity were determined by Western blot after UV exposure. The effect of Syk on MMP-1 expression in HDFs was further explored by either Syk siRNA or a selective Syk inhibitor. Possible downstream molecules of Syk were also evaluated in HDFs upon UV exposure. The relationship between Syk and collagenase was further explored in vivo (MMP-13, hairless mice). RESULTS Our studies in HDFs demonstrated that both a Syk inhibitor and Syk siRNA were able to inhibit MMP-1 expression in HDFs exposed to UV and that overexpression of Syk increased MMP-1 expression and the activity of JNK kinase, but not p38 or Erk1/2 MAP kinase. UV exposure enhanced both expression and activity of Syk in HDFs. Experiments with hairless mice suggested that Syk expression is an earlier indicator of UV exposure than MMP-13 expression. CONCLUSIONS Our results demonstrate that Syk expression correlates well with increase of MMPs (MMP-1 in humans and MMP-13 in mice) in response to UV exposure. The findings suggest that Syk may be a novel target for the prevention and treatment of skin photodamage by modulating MMPs.

Abstract
Acrylamide (ACR), benzopyrene [B(a)P] and trans-fatty acids (TFA) could be found to co-exist in many foods processed by high temperature. Our study investigated the effects of elaidic acid (ELA), a predominant TFA, on neuropathology induced by simultaneous exposure of ACR and B(a)P to mice. Results showed ELA enhanced the decrease of weight gains induced by simultaneous exposure of ACR and B(a)P (AB). Moreover, ELA enhanced ACR-induced increase of gait abnormality, B(a)P-induced damage to learning and memory, and AB-induced both of the damage above. Meanwhile, ELA enhanced B(a)Pinduced axonal degeneration in hippocamp, ACR- and AB-induced up-regulating of abnormal cerebellar Purkinje cells. ELA enhanced ACR-induced up-regulating of MDA in cerebrum and 8-OHdG in cerebrum and cerebellum; ELA enhanced B(a)P-induced up-regulating of MDA in cerebrum, PCO in cerebellum and 8-OHdG in cerebrum and cerebellum. Meanwhile, the enhancing role of ELA, on ACR-induced reduction of SOD activity in cerebrum and cerebellum, on B(a)P-induced reduction of GPx activity in cerebrum were found. Results suggested that ELA play a enhancing role on ACR-induced and B(a)P-induced oxidative damage, which attributable to the cerebral pathological lesion, and subsequent effect on gait abnormality and deficit on learning and memory in mice.

Abstract
Honey bee division of labor is characterized by temporal polyethism, in which young workers remain in the hive and perform tasks there, whereas old workers perform more risky outside tasks, mainly foraging. We present a model of honey bee division of labor based on (1) an intrinsic process of behavioral development and (2) inhibition of development through social interactions among the workers in a colony. The model shows that these two processes can explain the main features of honey bee temporal polyethism: the correlation between age and task performance; the age at which a worker first forages and how this age varies among hives; the balanced allocation of workers to hive tasks and foraging; the recovery of a colony from demographic perturbations; and the differentiation of workers into different behavioral roles. The model provides a baseline picture of individual and colony behavior that can serve as the basis for studies of more fine-grained regulation of division of labor.

Abstract
Obesity has been rising as a common social phenomenon. Recent research has convinced us that rather than a cosmetic problem, obesity should be considered as a real disease which is a complex disorder of appetite regulation and energy metabolism. Actually, obesity is caused by many factors such as heredity, environment and food contents, among which hereditary gene seems to work as a key element. Induced and followed by complicated factors, obesity is particularly associated with diabetes mellitus II, coronary heart disease, certain forms of cancer and so on. At present, the access to treat obesity is still in its early stage and the function of leptin identified in 1994 is also the focus of debate. This review provides a comprehensive insight into the epidemics, etiology, healthy problems, treatment strategies of obesity, and leptin as well, attempting to develop an outline of obesity research.

Abstract
There are increasing evidences to show that central nervous system is involved in the regulation of energy homeostasis. Energy intake is usually matched to energy expenditure over a period of time. Obesity occurs when the amount of energy intake (or food intake) is more than the energy expenditure. Because of the enormous tolls on human health taken by obesity and related disorders, an improved understanding of the control of food intake is an important priority. The aim of this article is to briefly review the advances in recent years on long-term maintenance of energy homeostasis and the role of central nervous system. In the present review, the following contents are included: (1) satiety and its production, (2) adiposity signals and the regulation of food intake, (3) nuclei in central nervous system involved in food intake, (4) the first- and the second-order neuronal signaling in hypothalamus on control of food intake and (5) clinic implications.

Abstract
Receptors for the constant region of IgG, Fc gamma receptors, are expressed on the surface of hematopoietic cells, where they mediate signaling events, such as phagocytosis, essential for host defense. Fc gamma receptors also play a role in the pathophysiology of autoimmune diseases. We have demonstrated that members of each of the three classes of human Fc gamma receptors, Fc gamma RI, Fc gamma RII, and Fc gamma RIII, mediate phagocytosis, but that important differences exist in their requirements for phagocytic signaling. For example, the Fc gamma receptors Fc gamma RI and Fc gamma RIIIA induce signaling largely by association with a gamma subunit containing a conserved cytoplasmic motif (ITAM) whose tyrosines are phosphorylated following receptor stimulation. Fc gamma RIIA contains a similar motif in its own cytoplasmic domain and does not require the gamma chain for phagocytic signaling. The tyrosine kinase Syk associates with the cytoplasmic domain of both the Fc gamma receptor gamma chain and Fc gamma RIIA and is required for phagocytosis by both Fc gamma receptor systems. To elucidate the differences in phagocytic signaling by the gamma chain and Fc gamma RIIA, we investigated the requirements for Fc gamma receptor/Syk co-immunoprecipitation, tyrosine phosphorylation, and phagocytosis. Both Fc gamma RIIA and the human gamma chain contain a tyrosine seven amino acids upstream of the ITAM motif. We observed that the upstream tyrosine plays a role in Fc gamma RIIA phagocytic signaling but is not involved in phagocytic signaling by the human gamma chain. Our data also indicate that the two ITAM tyrosines of the human gamma chain and Fc gamma RIIA do not contribute equally to Fc gamma receptor association with Syk kinase and phagocytic signaling. The data indicate that the carboxy-terminal tyrosine of the receptor cytoplasmic domain is especially important both for the interaction with Syk kinase and for phagocytosis. Elucidating such differences in gamma chain and Fc gamma RIIA signaling may be valuable in designing strategies for therapeutic intervention in hematopoietic and immunological disorders.

Abstract
OBJECTIVES To determine the effect of oral administration of a purified lipidic extract from Lepidium meyenii (MacaPure M-01 and M-02) on the number of complete intromissions and mating in normal mice, and on the latent period of erection (LPE) in rats with erectile dysfunction. METHODS Mice and rats were randomly divided into several experimental and control groups. A 10% ethanol suspension of M-01 and M-02 was orally administered for 22 days to the experimental groups according to the dosage specified by the experimental design. On day 22, 30 minutes after the dose was administered to the male mice, 2 virgin female mice were placed with 1 male mouse. The number of complete intromissions of each male mouse in 3 hours was recorded. In an assessment of 1 day of mating, each male mouse was cohabited with 5 estrous female mice overnight. The number of sperm-positive females was recorded. The LPE was measured to assess the sexual function in rats with erectile dysfunction. By using a YSD-4G multifunction instrument, an electric pulse at 20 V was applied to stimulate the rat's penis, and the duration from the start of the stimulus to full erection was measured in seconds as the LPE. RESULTS In the normal male mice, the number of complete intromissions during the 3-hour period was 16.33 +/- 1.78, 46.67 +/- 2.39, and 67.01 +/- 2.55 for the control group, M-01 group, and M-02 group, respectively. In the assessment of mating, the number of sperm-positive females increased from 0.6 +/- 0.7 in the control group to 1.5 +/- 0.5 in the M-01 experimental group. The LPE of male rats with erectile dysfunction was 112 +/- 13 seconds with a regular diet (control group). The oral administration of M-01 at a dose of 180 or 1800 mg/kg body weight and M-02 at a dose of 45, 180, or 1800 mg/kg body weight reduced the LPE to 54 +/- 12 seconds, 54 +/- 13 seconds, 71 +/- 12 seconds, 73 +/- 12 seconds, and 41 +/- 13 seconds, respectively. The LPE of the surgical rats treated with M-01 at the lowest dose (45 mg/kg) was 121 +/- 12 seconds; thus, the change was not significant. CONCLUSIONS Oral administration of M-01 and M-02 enhanced the sexual function of the mice and rats, as evidenced by an increase in the number of complete intromissions and the number of sperm-positive females in normal mice, and a decrease in the LPE in male rats with erectile dysfunction. The present study reveals for the first time an aphrodisiac activity of L. meyenii, an Andean Mountain herb.

Abstract
AIM The fine structural changes of Plasmodium berghei ANKA strain after treatment with the dihydroartemisinin (DATM) were observed. METHODS DATM 180 mg.kg-1.d-1 was given ig to outbreed NIH mice infected with P. berghei ANKA strain. Blood samples were collected, embedded and examined by electron microscopy. RESULTS In P. berghei ANKA strain, 1 h after drug administration, the parasites food vacuole membranes were destroyed, and the pigment grains showed some changes. The nucleus membrane, cytomembrane, and food vacuole membranes were stratified 2 h after administration. At the same time, swelling and separation of the outer and inner membrane or shrinking of the mitochondria were seen. Stripped nuclear and cytoplasm membrane were developed and vacuolizations were seen 4 h later. Eight hours after administration, a large number of parasite structures were destroyed except for a few parasite autophagic vacuoles. CONCLUSION DATM was a fast-acting and effective antimalarial drug. Its primary target is the membrane system. No obvious resistant characteristics were found upto 24 generations after resistant induction test for 4 months.
