Abstract
Objective: To analyze the clinical manifestations, therapeutic efficacy, prognosis and characteristics of NPC1 mutation in Chinese patients with Niemann-Pick disease type C(NPC). Methods: Ten unrelated Chinese NPC patients were diagnosed by NPC1 mutation analysis from July 2013 to February 2017 in Beijing Tian Tan Hospital of Capital Medical University. Clinical data of 10 cases were analyzed retrospectively which included clinical manifestations, laboratory results and NPC1 gene mutation features, and a series of follow-up were carried out about therapeutic efficacy and prognosis. Results: Ten patients suffering from NPC included 5 males and 5 females, aged from 42 days to 14 years when they presented to Tian Tan Hospital. According to their age of neurological onset, 4 were in early infantile period, 2 in late infantile period, 2 in juvenile periods, and the other 2 cases in neonatal period. They all presented with splenomegaly, 5 of 10 accompanied with hepatomegaly. Two cases of neonatal subtype presented mainly with delayed neonatal cholestatic jaundice and hepatosplenomegaly, accompanied with decreased muscle tone and slight psychomotor retardation. The other 8 cases presented with severe neurological involvement, such as progressive encephalopathy, ataxia and language impairment, 4 with dystonia, 3 with decreased muscle tension, 5 with vertical supranuclear gaze palsy, 5 with gelastic cataplexy, and 4 with epilepsy. Eight of 9 cases presented with foam cells in their bone marrow. Head MRI showed diffuse cerebral atrophy in 8 cases, thin corpus callosum in 2 cases, and brain white matter abnormal signals in 2 cases. Among 10 cases, 18 different mutations of NPC1 allelic genes were identified including 11 reported mutations, 3 novel missense mutations: c. 3683T>C (p.Met1128Thr), c.1926G>C (p.Met642Iie) and c. 3006C>G (p.Phe1002Leu), 2 novel nonsense mutation: c. 1142G>A(p.Trp381Ter ) and c. 3229C>T(p.Arg1077Ter), 1 novel minimal deletion mutation: c. 1385-1386del, and 1 novel intron mutation: c. 1757+ 5G>A. In 5 cases, the symptom of gelastic cataplexy was alleviated by imipramine, and the convulsion was relieved by valproate in 2 cases, by carbamazepine in 1 case at the beginning of seizure. During the 25 (3-66) months of follow-up, 4 cases died, the others' neurological symptoms were deteriorated progressively. Conclusions: The NPC1 gene mutation were high heterozygous in this group, and 7 novel mutations enriched the gene mutation spectrum of NPC1. The neurological manifestations were complicated in patients with NPC, and the symptomatology would be different according to their onset age of neurological symptoms. There might be effective symptomatic treatment for gelastic cataplexy by imipramine and for convulsion by valproate or carbamazepine.

Abstract
To determine if plasma exchange combined with plasma perfusion is a reliable and effective temporary liver support treatment for patients on the waiting list for OLT, we tested this method in 5 patients with end-stage and 3 patients with middle-stage severe hepatitis. Four patients were successfully controlled until a donor liver was available 4 to 13 days later. In contrast, the remaining 4 patients were not adequately controlled by this treatment and experienced aggravated disease progression, dying 3 to 8 days after treatment while still awaiting OLT. Of those 4 patients who received OLT, 2 patients died from multi-organ failure caused by hepatic failure, while the other 2 survived. These findings show that plasma exchange combined with plasma perfusion provides temporary support for some patients on the waiting list for OLT. The ability of patients to successfully bridge to OLT is closely associated with the degree of liver failure, complications, multi-organ failure, and the length of the waiting period for a donor liver.

Abstract
Aims: Chlorogenic acid (CGA) is a phenolic acid that has a wide range of pharmacological effects. However, the protective effects and mechanisms of CGA on liver fibrosis are not clear. This study explored the effects of CGA on miR-21-regulated TGF-β1/Smad7 liver fibrosis in the hepatic stellate LX2 cell line and in CCl4-induced liver fibrosis in Sprague-Dawley rats. Methods: The mRNA expression of miR-21, Smad7, connective tissue growth factor (CTGF), α-smooth muscle actin (α-SMA), tissue inhibitor of metalloproteinase 1 (TIMP-1), matrix metalloproteinase-9 (MMP-9), and transforming growth factor-β1 (TGF-β1) and the protein levels of Smad2, p-Smad2, Smad3, p-Smad3, Smad2/3, p-Smad2/3, Smad7, CTGF, α-SMA, TIMP-1, MMP-9 and TGF-β1 were assayed in LX2 cells and liver tissue. The effects of CGA after miR-21 knockdown or overexpression were analyzed in LX2 cells. The liver tissue and serum were collected for histopathological examination, immunohistochemistry (IHC) and ELISA. Results: The mRNA expression of miR-21, CTGF, α-SMA, TIMP-1, and TGF-β1 and the protein expression of p-Smad2, p-Smad3, p-Smad2/3, CTGF, α-SMA, TIMP-1, and TGF-β1 were inhibited by CGA both in vitro and in vivo. Meanwhile, CGA elevated the mRNA and protein expression of Smad7 and MMP-9. After miR-21 knockdown and overexpression, the downstream molecules also changed accordingly. CGA also lessened the degree of liver fibrosis in the pathological manifestation and reduced α-SMA and collagen I expression in liver tissue and TGF-β1 in serum. Conclusion: CGA might relieve liver fibrosis through the miR-21-regulated TGF-β1/Smad7 signaling pathway, which suggests that CGA might be a new anti-fibrosis agent that improves liver fibrosis.

Abstract
AIM The role of low-intensity extracorporeal shock wave therapy (LI-ESWT) in erectile dysfunction (ED) is not clearly determined. The purpose of this study is to investigate the short-term efficacy and safety of LI-ESWT for ED patients. MATERIALS AND METHODS Relevant studies were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG and VIP databases. Effective rate in terms of International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and Erectile Hardness Score (EHS) at about 1month after LI-ESWT was extracted from eligible studies for meta-analysis to calculate risk ratio (RR) of effective treatment in ED patients treated by LI-ESWT compared to those receiving sham-treatment. RESULTS Overall fifteen studies were included in the review, of which four randomized controlled trials (RCTs) were for meta-analysis. Effective treatment was 8.31 [95% confidence interval (CI): 3.88-17.78] times more effective in the LI-ESWT group (n=176) than in the sham-treatment group (n=101) at about 1 month after the intervention in terms of EHS, while it was 2.50 (95% CI: 0.74-8.45) times more in the treatment group (n=121) than in the control group (n=89) in terms of IIEF-EF. Nine-week protocol with energy density of 0.09mJ/mm2 and 1500 pluses seemed to have better therapeutic effect than five-week protocol. No significant adverse event was reported. CONCLUSION LI-ESWT, as a noninvasive treatment, has potential short-term therapeutic effect on patients with organic ED irrespective of sensitivity to PDE5is. Owing to the limited number and quality of the studies, more large-scale, well-designed and long-term follow-up time studies are needed to confirm our analysis.

Abstract
The IL-13Rα1 signaling pathway and M2 macrophages play crucial roles in schistosome egg-induced hepatic fibrosis via the expression of pro-fibrotic molecules. This study aims to investigate the inhibitory effect and mechanism of action of corilagin on schistosome egg-induced hepatic fibrosis via the IL-13Rα1 signaling pathway in M2 macrophages in vitro and in vivo. The mRNA and protein expression of IL-13Rα1, PPARγ, KLF4, SOCS1, STAT6, p-STAT6, and TGF-β was measured in vitro with corilagin treatment after IL-13 stimulation and in vivo corilagin treatment after effectively killing the adult schistosomes in schistosome-infected mice. Histological analysis of liver tissue was assessed for the degree of hepatic fibrosis. The results revealed that corilagin significantly reduced the expression of PPARγ, KLF4, SOCS1, p-STAT6, and TGF-β compared with model group and praziquantel administration (p < 0.01 or p < 0.05) in vivo and in vitro, which indicated a strong inhibitory effect of corilagin on IL-13Rα1 signaling pathway. As well, the inhibitory effect of corilagin showed a significant dose-dependence (p < 0.05). The area of fibrosis and distribution of M2 macrophages in mouse liver tissue were reduced significantly and dose-dependently with corilagin treatment compared to model group or praziquantel administration (p < 0.01 or p < 0.05), indicating that corilagin suppressed IL-13Rα1 signaling pathway and M2 macrophage polarization effectively in vivo. Furthermore, the anti-fibrogenic effect persisted even when IL-13Rα1 was up- or down-regulated in vitro. In conclusion, corilagin can suppress schistosome egg-induced hepatic fibrosis via inhibition of M2 macrophage polarization in the IL-13Rα1 signaling pathway.

Abstract
Dog allergy is common worldwide. However, the allergenicity of dog allergy is still unclear in China as well as in special group, such as children. In this study, we chose Can f 6, a major dog allergen which belongs to the lipocalin to study its allergenicity in Chinese dog allergic children. Can f 6 gene was subcloned into pET-28a vector and transformed into E. coli BL21 (DE3) cells for expression. The recombinant Can f 6 was purified by nickel affinity chromatography, identified by SDS-PAGE, and tested for its allergenicity by Western blot with sera and basophil activation test. Secondary structures, B cell epitopes and homology modeling of Can f 6 were predicted by using a series of bioinformatical approaches. And the verification of B cell epitopes was detected by ELISA. The recombinant allergen showed an explicit band with the molecular weight of 20 kDa by SDS-PAGE. Sera from 56.3 % (18/32) of dog-allergic children patients reacted with Can f 6. The induction of the expression of CD63 and CCR3 of dog allergic children in passively sensitized basophils was up to approximately 5.0 times higher than healthy subjects. The secondary structure of Can f 6 contains 3 α-helices, 9 β-sheets and random coils. Five B cell epitopes of Can f 6 were predicted and were confirmed successfully by ELISA. The results showed Can f 6 is a major allergen in Chinese children, which provides a basis for further study of Can f 6 in diagnosis and treatment of symptoms in children in China. The structural information of Can f 6 will help to form a foundation for the future design of vaccines and therapies for Can f 6 related allergies.

Abstract
Aberrant expression of lysine specific histone demethylase 1 (LSD1) has been increasingly associated with numerous cancer cells and several proof-of-concept studies are strongly suggestive of its potential as a druggable target. Tranylcypromine (TCP) is an antidepressant originally known to target the monoamine oxidases A and B (MAO-A and MAO-B), which are structurally related to LSD1. A number of TCP derivatives have been identified as potent LSD1 inhibitors, with a handful of them currently being tested in clinical trials. However, thus far the majority of structure-activity relationship studies reported on these TCP derivatives have been mostly limited to the racemates. In this study, we present the SAR data for a novel series of conformationally-restricted TCP-based LSD1 inhibitors, both in their racemic and enantiomerically pure forms. Compounds 18b and 19b were identified as the most potent LSD1 inhibitors within this series, possessing excellent selectivity (>10,000-fold) against MAO-A and MAO-B. These compounds activated CD86 expression on the human MV4-11 AML cells following 10 days of exposure, accompanied with the apparent cytotoxicity. Taken together, these findings are consistent with the pharmacological inhibition of LSD1 and further provide structural insights on the binding modes of these TCP derivatives and their enantiomers at the LSD1.

Abstract
Engineering of novel functional nanocomposite as like as the metallic nanocrystals supported non-stoichiometric perovskite nanomaterial in controlled parameters (size, shape and ratio of chemical characteristics) is a challengeable task. In this context, we present a facile route to fabricate and study its physicochemical property at real time mode in this report. Nanoscale pure Pb crystals surfaced on non-stoichiometric A-site deficient Pb1-xTiO3-y nanoparticle were fabricated when a precursor lead titanate (PbTiO3) nanoparticle was exposed to an electron beam irradiation (EBI) in a transmission electron microscope (TEM) at ambient temperature. In the state of the art, the chemical states and electronic structure of non-irradiated and irradiated PbTiO3 were studied by X-ray photoelectron spectroscopy (XPS). Electron bombardment resulted in a new visible feature at low binding energy in the Pb 4f core level, while Ti 2p and O 1s line shape showed slight changes. The Fermi level of the corresponding materials was determined to be 1.65 ± 0.1 eV and 2.05 ± 0.1 eV above the valence band maximum, respectively. The normal, weakly p-type PTO exhibits peculiar n-type feature after EBI process (The Fermi level moves near to the conduction band). A feasible mechanism is proposed involving the electron-stimulated local bond-breaking phenomenon in PbTiO3.

Abstract
Objective: To evaluate the feasibility of modified test system for sound localization (SL) in children. Methods: Modified system (6 male, 9 female) and traditional method ( 5 male, 5 female) were used for evaluation of minimum audible angle(MAA) and root-mean-square error(RMS) error of 4 to 6 years old children, and the results were compared to verify the accuracy and effectiveness of the modified test system for children sound localization.SPSS 17.0 software was used to analyze the data(t test). Results: (1) Comparison of veracity of modified system and traditional test: when tested at the positive front position using modified system, MAA and RMS error were(3.23±1.00)° and (13.68±5.18)° respectively.When using traditional method, MAA and RMS error were(3.17±0.59)°and (13.96±4.56)° respectively. No statistical differences were found between two groups(t value was 0.16, -0.14, both P>0.05). (2) Comparison of time used were as followed: when using modified system, it was (14.67±1.95) min for MAA, and (6.67±1.35) min for RMS error. When using traditional method, it was (36.30±6.81) min for MAA, and (21.00±3.50) min for RMS error. Time used were significant shorter in modified system than in traditional method (t value was-9.78, -12.37, both P<0.05). Conclusion: Modified test system for children sound localization is useful and reliable in children's horizontal SL test.The time used of modified test system is shorter than that of traditional test system.

Abstract
Acute chest pain caused by aortic dissection or acute myocardial infarction (AMI) is one of the most serious medical emergencies and requires very quick differential diagnosis to seize the best time for treatment. Aortic dissection and acute myocardial infarction are manifested with similar symptoms, making it difficult to differentially diagnose these two conditions. The present case was initially misdiagnosed as an acute non-ST-segment elevation myocardial infarction (NSTEMI) with left aortic disease, and then diagnosed by coronary angiography examination as type A aortic dissection (AAD). This case points to the need to collect and analyze as much patient clinical data as possible, including medical history and the results of auxiliary examination which would help to avoid misdiagnosis or treatment delay and reduce mortality among patients with type AAD when they manifest symptoms of chest pain and an ECG pattern of NSTEMI.

Abstract
Chlorinated polycyclic aromatic hydrocarbons (ClPAHs) with three to five aromatic rings have been documented to ubiquitously occur in environmental matrices. In this study, residual concentrations and profiles of 20 individual ClPAHs were determined in 35 surface sediment samples from Maowei Sea, a semi-enclosed shallow inland bay located in the northwestern part of South China Sea. The concentrations of ΣClPAHs in sediment ranged from 313 to 9650 pg/g dw with a detection rate of 43-100%. Of the individual ClPAH congeners, 9-ClPhe was the most abundant in Maowei Sea with the concentrations that ranged from 99.9 to 3610 pg/g dw (mean 1120 pg/g dw). High-molecular-weight ClPAH congeners (four to five rings) were predominant in sediments from sampling locations near a petrochemical industrial complex, whereas low-molecular-weight ClPAH congeners (three rings) were predominant in sediments from estuarine and mangrove locations. A positive matrix factorization (PMF) model in combination with dioxin-like toxic equivalency quotient (TEQ) results was used to apportion sources of ClPAHs. Vehicular emission, combustion/chemical industrial processes, and two other unknown sources accounted for 40.1, 25.5, 20.8, and 13.6%, respectively, of ClPAH sources in sediment; their contribution to TEQs in sediments were 24.2, 40.5, 19.3, and 16.0%, respectively. Further investigations are needed to elucidate potential sources and ecological risks of ClPAHs in sediments.

Abstract
Due to its antimicrobial properties and low toxicity, human lysozyme (hLYZ) has broad application in the medical field and as a preservative used by the food industry. However, limited availability hinders its widespread use. Hence, we constructed a recombinant avian adeno-associated virus (rAAAV) that would specifically express hLYZ in the chicken oviduct and harvested hLYZ from the egg whites of laying hens. The oviduct-specific human lysozyme expression cassette flanked by avian adeno-associated virus (AAAV) inverted terminal repeats (ITRs) was subcloned into the modified baculovirus transfer vector pFBX, and then the recombinant baculovirus rBac-ITRLYZ was generated. The recombinant avian adeno-associated virus was produced by co-infecting Sf9 cells with rBac-ITRLYZ and the other 2 baculoviruses containing AAAV functional genes and structural genes, respectively. Electron microscopy and real-time PCR revealed that the recombinant viral particles were generated successfully with a typical AAAV morphology and a high titer. After one intravenous injection of each laying hen with 2 × 1011 viral particles, oviduct-specific expression of recombinant human lysozyme (rhLYZ) was detected by reverse transcription-PCR. The expression level of rhLYZ in the first wk increased to 258 ± 11.5 μg/mL, reached a maximum of 683 ± 16.4 μg/mL at the fifth wk, and then progressively declined during the succeeding 7 wk of the study. Western blotting indicated that the oviduct-expressed rhLYZ had the same molecular weight as the natural enzyme. These results indicate that an efficient and convenient oviduct bioreactor mediated by rAAAV has been established, and it is useful for production of other recombinant proteins.

Abstract
Although elastic strains, particularly inhomogeneous strains, are able to tune, enhance or create novel properties of some nanoscale functional materials, potential devices dominated by inhomogeneous strains have not been achieved so far. Here we report a fabrication of inhomogeneous strains with a linear gradient as giant as 106 per metre, featuring an extremely lower elastic energy cost compared with a uniformly strained state. The present strain gradient, resulting from the disclinations in the BiFeO3 nanostructures array grown on LaAlO3 substrates via a high deposition flux, induces a polarization of several microcoulomb per square centimetre. It leads to a large built-in electric field of several megavoltage per metre, and gives rise to a large enhancement of solar absorption. Our results indicate that it is possible to build up large-scale strain-dominated nanostructures with exotic properties, which in turn could be useful in the development of novel devices for electromechanical and photoelectric applications.

Abstract
BACKGROUND Previous studies have demonstrated that self-control is positively related to life satisfaction, but this association in Chinese employees and its underlying mechanism are less commonly investigated. OBJECTIVE In this preliminary study the relationships between self-control and life satisfaction and the mediating effect of job satisfaction were tested. METHOD Participants were 482 full-time employees (188 male, 294 female) from different cities in China. They answered self-report questionnaires online that assessed self-control, job satisfaction, and life satisfaction. Path analyses were conducted and bootstrap technique was used to judge the significance of the mediation. RESULTS Self-control was positively related to both job and life satisfaction. More importantly, job satisfaction significantly mediated the association between self-control and life satisfaction. Furthermore, there was no significant difference in the size of the mediating effect between intrinsic and extrinsic job satisfaction. CONCLUSIONS Results of this preliminary study provide further evidence of the positive association between self-control and life satisfaction. Job satisfaction is found to mediate this relationship.

Abstract
Oxaliplatin, a platinum-based chemotherapeutic agent, is an important first-line drug in the treatment of colorectal cancers, but drug resistance causes treatment failure. It has been reported that gap junctional communication can enhance the cytotoxicity of platinum drugs. The gap junction formed of connexin proteins provides a direct pathway for electrical and metabolic cell-cell interaction. The voltage-dependent gating of gap junction allows small hydrophilic molecules and ions to permeate to adjacent cells. Connexin 43 is a diagnostic marker for cancer therapy and the predominant connexin isoform in many cell types. The purpose of this study was to investigate the role of connexin 43 in oxaliplatin activity by using colorectal cancer cell lines. LoVo and HCT116 cell lines were used for analysis. Connexin 43 expression was confirmed by western blot and immunocytochemistry. MTT, western blot, "Parachute" dye-coupling assays and reactive oxygen species measurement were used to detect cytotoxicity and the inhibition of connexin 43 expression induced by oxaliplatin. Results showed that connexin 43 enhanced oxaliplatin cytotoxicity through gap junctional communication function and high concentration of oxaliplatin inhibited connexin 43 expression to counteract its cytotoxicity. This study suggested that connexin 43 could be considered a molecular target of oxaliplatin activity in colorectal cancer.

Abstract
OBJECTIVE To investigate the influences of repeated propofol anesthesia on the hippocampal apoptosis and the long-term learning and memory abilities of neonatal rats. METHODS In the study, 45 male Sprague-Dawley rats, aged 7 days, were randomly divided into 3 group (n=15 each): control group (C group) that received intralipid 7.5 mL/kg intraperitioneal (IP) once a day×7 days; group propofol 1 (P1) that received propofol 75 mg/kg IP once a day×7 days; group propofol 2 (P2) that received intralipid 7.5 mL/kg IP once a day×6 days+propofol 75 mg/kg IP on the 7th day. In each group, 5 animals were chosen and arterial blood samples were obtained immediately after the animals were fully awake for blood gas analysis. Learning and memory abilities were assessed using Morris water maze when the other rats were 4 weeks old. The animals were decapitated after the tests. The hippocampi were isolated for detection of neuron-specific nucleoprotein (NeuN) expression by immunohistochemistry method and the expression of caspase-3 using the Western blot. RESULTS There was no significant difference in the indexes of blood gas analysis among the 3 groups. Morris water maze test: compared with group C, the escape latency and the length of searching on the 5th day were significantly prolonged, and the searching time in target quadrant and platform crossing on the 6th day were significantly decreased in group P1 (P<0.05) but not in group P2. Compared with group C, NeuN-positive neurons were decreased, and the expression of caspase-3 was increased in the rats of group P1 (P<0.05) but not in group P2. CONCLUSION Repeated propofol anesthesia may destroy long-term learning and memory abilities by inducing apoptosis of hippocampal neurons in neonatal rats, while single dose of propofol has no obvious effect on the hippocampal apoptosis and long-term learning and memory of neonatal rats.

Abstract
Objective:The aim of this study was to demonstrate the risk factors which affect the exposure of glottis in suspension laryngoscopy.Method:We performed a prospective study about 90 cases of vocal cord lesions underwent microlaryngosurgery(including polyps,vocal nodules,cyst and papilloma).Then we recorded the clinical data related to glottic exposure, both preoperatively and intraoperatively. Result:Univariate analysis showed that parameters like age(P=0.038), Cormack-Lehane score(P=0.007),maximuminterincisors gap(P=0.007),hyoid-mental distance(HMD) in full extension(P=0.033), thyroid-mental distance(TMD) in full extension(P=0.014), vertical thyroid-mental distance(VTMD) in full extension(P=0.042), sternum-mental distance(SMD) in full extension(P=0.01) and degree of neck flexion-extension(P=0.003) were related to intraoperative difficult exposure of the glottic area.In logistic regression analysis, Cormack-Lehane score(P=0.003), maximuminterincisors gap(P=0.001) and degree of neck flexion-extension(P=0.002) were significantly risk factors of difficult laryngealexposure. Conclusion:Combination of Cormack-Lehane score, maximuminterincisors gap and degree of neck flexion-extensionmay help to predict the difficult laryngealexposure, so we should evaluate patients before operations of suspension laryngoscopy to decrease the surgical complication.

Abstract
OBJECTIVE To investigate the preventive and therapeutic effects of rapamycin (RAPA) on autoimmune hepatitis and liver fibrosis induced by concanavalin A (ConA) and possible mechanisms. METHODS Female C57BL/6 mice aged 8 weeks were randomly divided into normal control group, ConA model group, and ConA+RAPA treatment group. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured; hematoxylin-eosin and Masson staining and Knodell HAI and Ishak scoring systems were used to evaluate the degrees of liver inflammation and fibrosis. Gradient centrifugation was used to separate mononuclear cells, flow cytometry was used to measure CD4(+)/CD8(+) ratio, and intracellular cytokine staining was performed to measure the levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-10 (IL-10), and transforming growth factor β (TGF-β) in immune cells. The t-test was used for data comparison between groups. RESULTS The RAPA treatment group showed a significant reduction in serum ALT level compared with the ConA model group (P < 0.05). Liver inflammatory injury was reduced significantly, and there was no obvious fibrous tissue proliferation. The level of TGF-β in mononuclear cells was reduced significantly, and the treatment group had a significantly lower level of TGF-β than the model group (8.91%±1.25% vs 16.65%±2.05%, P < 0.05). The proportions of CD4(+) and CD8(+)T cells in the liver were reduced, and the treatment group had significantly lower proportions of CD4(+) and CD8(+)T cells than the model group (proportion of CD4(+)T cells: 4.09%±1.20% vs 8.91%±0.69%, P < 0.05; proportion of CD8(+)T cells: 3.28%±0.66% vs 9.68%±1.46%, P < 0.05). The proportion of Th1 cells was reduced, and the treatment group had a significantly lower proportion of Th1 cells than the model group (1.02%±0.06% vs 2.83%±0.21%, P < 0.05); the proportions of Th3 and Tr1 regulatory T cells were increased, and the treatment group had significantly higher proportions of Th3 and Tr1 regulatory T cells than the model group (proportion of Th3 regulatory T cells: 59.53%±9.82% vs 47.13%±4.79%, P < 0.05; proportion of Tr1 regulatory T cells: 10.63%±2.27% vs 7.09%±1.66%, P < 0.05), but the proportion of Th2 cells showed no significant difference between the two groups (P > 0.05). CONCLUSION RAPA can promote the differentiation of Th3/Tr1 cells, reduce the expression of TGF-β in mononuclear cells, slow down the progression of chronic hepatitis induced by ConA into liver fibrosis, and thus prevent liver fibrosis.

Abstract
OBJECTIVE microRNAs (miRNAs) plays an important role in tumor development and progression and act as oncogenes or tumor suppressor genes in the carcinogenesis process. miRNA is stable in serum, and recent studies have demonstrated the feasibility of using circulating miRNA as biomarkers in cancer patients. However, currently, no serum biomarkers for the early diagnosis and prognosis of renal cell carcinoma (RCC) have been reported. Therefore, a new molecular marker for early diagnosis and evaluation of recurrence after surgery is required. Our purpose was to identify miRNA signatures that could distinguish the serum of RCC patients from matched healthy controls and validate identified miRNAs as potential biomarkers for RCC. METHOD Serum samples from 30 RCC patients were collected before and 1 month after surgery. 30 cancer-free blood donor volunteers with no history of any cancer were recruited from the same institute. miR-21 and miR-106a expression levels were determined by real-time PCR. RESULT The serum miR-21 level was significantly higher in RCC patients (median, 8.34) than in healthy control individuals (median, 0.70; p= 0.001). A month after surgery, serum miR-21 levels (median, 0.69) were significantly reduced (p= 0.032). The serum miR-106a level was higher in RCC patients (median, 8.99) compared with controls (median, 0.96; p= 0.000), while miR-106a levels (median, 1.01) were reduced a month after surgery (p= 0.028). The expression level of miR-21 and miR-106 a in RCC patients increased significantly, while miR-21 and miR-106a decreased after surgery. This outcome suggests that serum miR-21 and miR-106a expression level was closely related with kidney cancer tissue. CONCLUSION We conclude that serum miR-21 and miR106a are expected to be molecular markers for RCC.

Abstract
The community structure of colonised bacteria in the gastrointestinal tracts (GITs) of pre-weaned calves is affected by extrinsic factors, such as the genetics and diet of the calves; however, the dietary impact is not fully understood and warrants further research. Our study revealed that a total of 6, 5, 2 and 10 bacterial genera showed biologically significant differences in the GITs of pre-weaned calves fed four waste-milk diets: acidified waste milk, pasteurised waste milk, untreated bulk milk, and untreated waste milk, respectively. Specifically, generic biomarkers were observed in the rumen (e.g., Bifidobacterium, Parabacteroides, Fibrobacter, Clostridium, etc.), caecum (e.g., Faecalibacterium, Oxalobacter, Odoribacter, etc.) and colon (e.g., Megamonas, Comamonas, Stenotrophomonas, etc.) but not in the faeces. In addition, the predicted metabolic pathways showed that the expression of genes related to metabolic diseases was increased in the calves fed untreated waste milk, which indicated that untreated waste milk is not a suitable liquid diet for pre-weaned calves. This is the first study to demonstrate how different types of waste milk fed to pre-weaned calves affect the community structure of colonised bacteria, and the results may provide insights for the intentional adjustment of diets and gastrointestinal bacterial communities.

Abstract
Antibody-drug conjugates (ADCs), constructed with monoclonal antibodies (mAbs), linkers, and natural cytotoxins, are innovative drugs developed for oncotherapy. Owing to the distinctive advantages of both chemotherapy drugs and antibody drugs, ADCs have obtained enormous success during the past several years. The development of highly specific antibodies, novel marine toxins' applications, and innovative linker technologies all accelerate the rapid R&D of ADCs. Meanwhile, some challenges remain to be solved for future ADCs. For instance, varieties of site-specific conjugation have been proposed for solving the inhomogeneity of DARs (Drug Antibody Ratios). In this review, the usages of various natural toxins, especially marine cytotoxins, and the development strategies for ADCs in the past decade are summarized. Representative ADCs with marine cytotoxins in the pipeline are introduced and characterized with their new features, while perspective comments for future ADCs are proposed.

Abstract
Tunicamycin (TM) induces endoplasmic reticulum (ER) stress and inhibits N-glycosylation in cells. ER stress is associated with neuronal death in neurodegenerative disorders, such as Parkinson's disease and Alzheimer's disease, and most patients complain of the impairment of olfactory recognition. Here we examined the effects of TM on aversive olfactory learning and the underlying synaptic plasticity in the main olfactory bulb (MOB). Behavioral experiments demonstrated that the intrabulbar infusion of TM disabled aversive olfactory learning without affecting short-term memory. Histological analyses revealed that TM infusion upregulated C/EBP homologous protein (CHOP), a marker of ER stress, in the mitral and granule cell layers of MOB. Electrophysiological data indicated that TM inhibited tetanus-induced long-term potentiation (LTP) at the dendrodendritic excitatory synapse from mitral to granule cells. A low dose of TM (250nM) abolished the late phase of LTP, and a high dose (1μM) inhibited the early and late phases of LTP. Further, high-dose, but not low-dose, TM reduced the paired-pulse facilitation ratio, suggesting that the inhibitory effects of TM on LTP are partially mediated through the presynaptic machinery. Thus, our results support the hypothesis that TM-induced ER stress impairs olfactory learning by inhibiting synaptic plasticity via presynaptic and postsynaptic mechanisms in MOB.

Abstract
The spotted knifejaw, Oplegnathus punctatus, is an important aquaculture fish species in China. To better understand the chromosomal microstructure and the karyotypic origin of this species, cytogenetic analysis was performed using Giemsa staining to identify metaphase chromosomes, C-banding to detect C-positive heterochromatin, silver staining to identify the nucleolus organizer regions (Ag-NORs), and fluorescence in situ hybridization (FISH) for physical mapping of the major (18S rDNA) and minor (5S rDNA) ribosomal genes. The species showed a karyotype of 2n = 48 for females, composed of 2 submetacentric and 46 telocentric chromosomes, with a fundamental number (FN) = 50, while the karyotype of males was 2n = 47, composed of 1 exclusive large metacentric, 2 submetacentric, and 44 telocentric chromosomes, with FN = 50. These karyotype results suggest that O. punctatus might have an X1X1X2X2/X1X2Y multiple sex chromosome system. C-positive heterochromatin was distributed in the centromeres of all chromosomal pairs and in the terminal portions of some chromosomes. A single pair of Ag-positive NORs was found to be localized at the terminal regions of the short arms of the subtelocentric chromosome pair, which was supported by FISH of 18S rDNA. After FISH, 5S rDNA were located on the interstitial regions of the smallest telocentric chromosome pair. This study was the first to identify the karyotype of this species and will facilitate further research on karyotype evolution in the order Perciformes.

Abstract
Objective: To investigate effects of mammalian target of rapamycin (mTOR)- cell division cycle 42 (Cdc42) signaling pathway on phagocytosis of alveolar macrophages (AMs) in chronic obstructive pulmonary disease (COPD) mice. Methods: Forty mice were randomly divided into control group and model group. Each group contained 20 mice. COPD model group were established by cigarette smoking exposure. AMs were isolated from lung tissue by discontinuous density gradient centrifugation. AMs from control group were divided into health control group and rapamycin control group while AMs from model group were divided into COPD group and rapamycin COPD group. The AMs from rapamycin control group and rapamycin COPD group were incubated with a final concentration of 10 nmol/L rapamycin for 24 hours. Mean fluorescence intensity (MFI) and the positive percent of alveolar macrophage engulfed flurescein isothiocyanate-labeled Escherichina coli (FITC-E.coli) AM (AM%) were detected by flow cytometry. Real time PCR (RT-PCR) and Western blot were applied to detect mRNA and protein. The activity of Cdc42 was detected by G-LISA Small GTPase Activation Assays (G-LISA) Cdc42 Kit. The cytoskeleton structure of AM was observed by laser scanning confocal microscopy. Results: MFI and AM% in COPD group were decreased than those in health control group[4 060±590 vs 9 190±988 and (28.65±1.26)% vs (67.50±4.56)%]; Compared with COPD group, MFI and AM% in rapamycin COPD group[4 856±762, (38.31±1.71)%]were increased (all P<0.05). The expression of mRNA, protein and activity of mTOR in COPD group were increased than those in health control group[(2.62±0.46, 1.30±0.52, 1.46±0.43) vs (1.00±0.00, 0.48±0.27, 0.58±0.26)]; compared with COPD group, the expression of mRNA, protein and activity of mTOR in rapamycin COPD group (1.40±0.36, 0.90±0.66, 0.92±0.28) were decreased (all P<0.05). The Cdc42 mRNA, protein and activity in COPD group were higher than those in health control group[(2.56±0.50, 1.61±0.37, 0.46±0.09) vs (1.00±0.00, 0.67±0.22, 0.30±0.07)](all P<0.01); compared with COPD group, the expression of mRNA, protein and activity of Cdc42 in rapamycin COPD group (1.38±0.34, 0.91±0.48, 0.36±0.06) were decreased (all P<0.01). Filopodia protruding can not be seen in the cytoskeleton of AMs from health control group and rapamycin control group; some filopodia protruding can be seen in AM from COPD group; some long filopodia protruding can be seen in AM from rapamycin COPD group. Negative correlations were existed between the mRNA, protein and activity of mTOR, Cdc42 and MFI in all group. Conclusions: mTOR-Cdc42 signaling pathway is activated and related to phagocytosis deficiency of AM in COPD. It can be inferred that the pathway is involved in the pathogenesis of COPD.

Abstract
Talipes equinovarus is a common congenital deformity. COL9A1 polymorphisms are associated with the development of articular cartilage-related diseases. In the current study, we evaluated the relationship between COL9A1 rs1135056, rs35470562, and rs592121 genetic polymorphisms and risk of congenital talipes equinovarus. Between January 2013 and July 2015, 87 children with congenital talipes equinovarus and 174 control subjects were recruited from the Fourth People's Hospital of Shaanxi and the First Hospital of Yulin. Genotyping of COL9A1 rs1135056, rs35470562, and rs592121 was performed using polymerase chain reaction-restriction fragment length polymorphism. Using conditional regression analysis, the AA genotype of COL9A1 rs35470562 was found to be significantly associated with increased risk of congenital talipes equinovarus compared to the GG genotype [odds ratio (OR) = 2.60, 95% confidence interval (CI) = 1.06-6.32]. In addition, under a recessive model, rs35470562 AA carriers were observed to be at higher risk for this condition in comparison to individuals with GG or GA genotypes (OR = 2.23, 95%CI = 1.03-5.04). However, no significant relationship was established between the COL9A1 rs1135056 and rs592121 polymorphisms and congenital talipes equinovarus in any of the genetic models tested. In conclusion, our results indicate that the COL9A1 rs35470562 variant may contribute to congenital talipes equinovarus susceptibility in the Chinese population examined.

Abstract
An instrument used for measuring multiple scintillators' light output and energy resolution was developed. The instrument consisted of a light sensor array which was composed of 64 discrete SiPMs (Silicon Photomultipliers), a corresponding individual channel readout electronics system, and a data processing algorithm. A Teflon grid and a large interval between adjacent SiPMs were employed to eliminate the optical cross talk among scintillators. The scintillators' light output was obtained by comparing with a reference sample with known light output. Given the SiPM temperature dependency and the difference among each SiPM, a temperature offset correction algorithm and a non-uniformity correction algorithm were added to the instrument. A positioning algorithm, based on nine points, was designed to evaluate the performance of a scintillator array. Tests were performed to evaluate the instrument's performance. The uniformity of 64 channels for light output measurement was better than 98%, the stability was better than 98% when temperature varied from 15 °C to 40 °C, and the nonlinearity under 511 keV was better than 2%. This instrument was capable of selecting scintillators and evaluating the packaging technology of scintillator arrays with high efficiency and accuracy.

Abstract
Hematologic disease has become a common disease that produces harm and burdens to human individuals today, seriously threatening public health care. Particularly, the damage caused by malignant hematologic disease has been recognized by doctors and patients. However, low cure rate and high recurrence rate are the main issues when treating malignant hematologic disease by current methods. The survival rate could be significantly improved if the early metaphase diagnosis rate could be improved. Therefore, early diagnosis is important for malignant hematologic disease at molecular level. In recent years, the bio-electrochemical method for tumor cells and blood detection has attracted more and more attention. Because many cancer cell surface proteins are important biomarkers, changing in the surface proteins'quantity and condition as well as a variety of electrophysiological activity often show some potential diseases. Each cancer cell has a specific biomarker to distinguish it from the normal cell line. As a result, their biomarkers can be detected by bioelectrochemical techniques. Therefore, it provides theoretical and experimental support for detecting the cancer cell activity, diagnosis and treatment of diseases, and screening the drugs. In recent years, the development of biosensor, nanotechnology, probe and electrode, as well as Lab-on-a-chip has contributed a lot to the development of bioelectrochemistry, especially the development of the inspection and drug resistance in hematological and oncological diseases. This review lists the different composition of bio-electrochemical technology, focusing on the progress in hematologic field so as to put forward the research.

Abstract
OBJECTIVE To investigate the effect of smoking status, cumulative smoking exposure and smoking cessation on the outcomes of patient with non-muscle-invasive bladder cancer (NMIBC). METHODS We collected smoking data from 484 patients with NMIBC who were treated with transurethral resection (TUR); smoking status was categorized as (never smokers vs current smokers vs former smokers). Cumulative smoking exposure was categorized as high smoking exposure (cigarette index ≥400) versus low smoking exposure (cigarette index <400). Association with outcomes was examined by multivariable analyses after adjusting for the effects of standard clinicopathologic factors, and the Kaplan-Meier method was used to estimate the effect of smoking status and cumulative smoking exposure on RFS. RESULTS A total of 168 (34.7 %) patients were never smoker, 121 (25 %) patients were current smokers, and 195 (40.3 %) patients were former smokers. The median follow-up was 25 months. By multivariate analysis, pathological grade (p = 0.013), history of recurrence (p < 0.001), number of tumors (p < 0.001) and size of tumors (p = 0.013) were significantly associated with tumor recurrence; nevertheless, smoking status did not influence tumor recurrence (p = 0.063). Among current and former smokers, cumulative smoking exposure was significantly associated with tumor recurrence (p < 0.001), compared to current smokers, patients with smoking cessation ≥10 years had a lower risk of tumor recurrence [hazard ratio (HR) 0.456, p = 0.007]. CONCLUSIONS Smoking affects the prognosis of patient with NMIBC, which is still controversial; however, among ever smokers, a high cumulative exposure smoking can significantly increase the risk of tumor recurrence. Quitting smoking might be associated with a lower recurrence rate for patients with NMIBC.

Abstract
Studies on scarlet fever with meteorological factors included were few. We aimed to illustrate meteorological factors' effects on monthly incidence of scarlet fever. Cases of scarlet fever were collected from the report of legal infectious disease in Hefei City from 1985 to 2006; the meteorological data were obtained from the weather bureau of Hefei City. Monthly incidence and corresponding meteorological data in these 22 years were used to develop the model. The model of auto regressive integrated moving average with covariates was used in statistical analyses. There was a highest peak from March to June and a small peak from November to January. The incidence of scarlet fever ranges from 0 to 0.71502 (per 105 population). SARIMAX (1,0,0)(1,0,0)12 model was fitted with monthly incidence and meteorological data optimally. It was shown that relative humidity (β = -0.002, p = 0.020), mean temperature (β = 0.006, p = 0.004), and 1 month lag minimum temperature (β = -0.007, p < 0.001) had effect on the incidence of scarlet fever in Hefei. Besides, the incidence in a previous month (AR(β) = 0.469, p < 0.001) and in 12 months before (SAR(β) = 0.255, p < 0.001) was positively associated with the incidence. This study shows that scarlet fever incidence was negatively associated with monthly minimum temperature and relative humidity while was positively associated with mean temperature in Hefei City, China. Besides, the ARIMA model could be useful not only for prediction but also for the analysis of multiple correlations.

Abstract
This study investigated the properties of flocs and effects of the solution pH on removal of representative pollutants by enhanced coagulation with variable charge soils of South China and polyaluminum chloride (PAC). The results demonstrated that the removal efficiency of turbidity was larger and the aggregated flocs had a faster growth rate, bigger size, denser structure and faster settling rate than those generated by PAC alone, when variable charge soil was used in conjunction with PAC. Additionally, initial solutions pH had meaningful effects on removal of pollutants. With the increase in the pH of the solution, the removal efficiencies of turbidity, algae and heavy metal ions significantly increased. Besides, charge neutralization together with physical entrapment of colloids was the dominant mechanism in enhanced coagulation, and variable charge soil displayed a great adsorption effect.

Abstract
OBJECTIVE To evaluate the prognostic value of combination of plasma brain natriuretic peptide(BNP) with the ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity(E/E') in the patients with septic shock. METHODS From June 2012 to December 2013 , 127 patients with septic shock were consecutively recruited and underwent trans-thoracic echocardiography examination within 6 h after admission to Intensive Care Unit(ICU), Zhejiang Provincial People's Hospital. Plasma BNP concentration was measured using ELISA method. All Clinical, laboratory, and survival data were prospectively collected. RESULTS Of 127 patients enrolled, mean values for age were(59.9±17.3) years and APACHE Ⅱ score(16.8±5.8), respectively. 95 patients(74.8%) took mechanical ventilation. 28- , 60-day mortality rate was 36.3% and 42.3%, respectively. Univariate Cox regression analysis showed that age, coronary artery disease, serum creatinine and lactate, plasma BNP, left ventricular ejection fraction(LVEF), E/E' and APACHE Ⅱ score were significantly(P≤0.05) associated with 60-day mortality. Multivariate analysis revealed that serum lactate, plasma BNP(χ(2)=9.4, P=0.002) , E/E'(χ(2)=4.89, P=0.02) and APACHE Ⅱ score(χ(2)=10.6, P=0.001) remained independent predictors for 60-day mortality. ROC curve analysis showed that the optimal plasma BNP and E/E' cutoff values identified were 338.8 pg/ml and 10.8, and the areas under ROC curve were 0.89(sensitivity: 83.7%; specificity: 81.4%)and 0.83(sensitivity: 76.7%; specificity: 72.9%)for 60-day mortality, respectively. In addition to plasma BNP and clinical predictors, the E/E' could provide in independent and incremental prognostic value of 60-day mortality(χ(2)=59.3 vs 47.8, P<0.001). CONCLUSION Plasma BNP and E/E' are independent predictors for 60-day mortality, and combination of plasma BNP and E/E' could improve risk stratification in patients with septic shock.

Abstract
Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis in the skin and internal organs. The pathogenesis of SSc is not completely understood until now. Recently, many studies have focused on the role of E3 ubiquitin ligases in organ fibrosis. However, the possible regulatory mechanisms of E3 ubiquitin ligases in fibrosis and SSc are not well documented. In this review, we summarized that E3 ubiquitin ligases regulated fibrosis through ubiquitin-mediated degradation of TGF-β/Smad signaling pathway. Moreover, E3 ubiquitin ligases participated in regulating fibrosis by other methods, such as inducing epithelial transition to mesenchymal cell, enhancing the production of TGF-β and protecting activated hepatic stellate cells from apoptosis. However, the specific regulatory mechanisms of E3 ubiquitin ligases in scleroderma is still not fully understood. There are more works to be done to specify the mechanism of E3 ubiquitin ligases in regulation of fibrosis in SSc.

Abstract
BACKGROUND Systemic sclerosis is an chronic inflammatory autoimmune diseases. Adipokine has been reported to play an important role in modulating immune responses. Recent studies suggest that adipokine also plays some roles in the pathogenesis of systemic sclerosis (SSc). However, published data regarding the relationship between plasma/serum adipokine levels and SSc are contradictory. The aim of this study was at performing a meta-analysis to derive a more accurate estimation and further investigate the association of plasma/serum leptin and adiponectin levels with SSc patients. METHODS PubMed, and Web of Science databases (up to Feb 20, 2016) were used to obtain all relative published literatures. The study quality was assessed by the Newcastle-Ottawa scale. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by random-effect model analysis. RESULTS A total of fourteen studies were finally included in this meta-analysis. Among them, six of which were studied for the serum adiponectin levels in SSc patients, six of which were studied for the serum leptin levels in SSc patients, and two of them were studied both for serum adiponectin levels and serum leptin levels in SSc patients. The meta-analysis results showed that the serum adiponectin levels in SSc patients were significantly lower than that in normal controls (SMD = -0.608 ng/ml, 95% CI = -1.029 to -0.186, p = 0.005). However, there were no significant differences in serum leptin levels between SSc patients and healthy controls (SMD = -0.990 ng/ml, 95% CI = -2.340 to 0.359, p = 0.150). The subgroup analysis showed that Asia SSc patients with age less than 50 years old had lower plasma/serum adiponectin levels when compared with controls. CONCLUSION The serum adiponectin levels, but not serum leptin levels, in SSc patients were significantly lower than that in normal controls.

Abstract
Over-utilization of germplasms that are resistant to the soybean cyst nematode (SCN) in soybean breeding programs can lead to genetic vulnerability in resistant cultivars. Resistant wild soybean (Glycine soja) is considered an invaluable gene source for increasing the genetic diversity of SCN resistance. In this study, we genotyped 23 G. soja accessions that are resistant to SCN race 3 for polymorphisms in the resistance genes, rhg1, Rhg4, and SHMT, and investigated their genetic relationship with eight Glycine max resistant cultivars. We identified 89 single nucleotide polymorphisms (SNPs) and 11 DNA insertion-deletions (InDels), of which 70 SNPs and 8 InDels were found in rhg1, 9 SNPs were found in Rhg4, and 10 SNPs and 3 InDels were found in SHMT. Nucleotide diversity was π = 0.00238 and θ = 0.00235, and haplotype diversity was 1.000. A phylogenetic tree comprising four clusters was constructed using sequence variations of the 23 G. soja and 8 G. max resistant accessions. Five G. soja accessions in subcluster A2, and four G. soja accessions in cluster B were genetically distant from G. max genotypes. Eight resistance-associated SNPs in the three resistance genes formed nine haplotypes in total. G. soja resistant accessions had different haplotypes (H2, H4, H5, H6, H7, and H8) compared with those of G. max (H1, H3, and H9). These results provide vital information on the use of wild soybeans for broadening the genetic base of SCN resistance.

Abstract
BACKGROUND Measles is one of the most highly contagious diseases which have not been eliminated in China. This study aimed to investigate the epidemiological characteristics of measles in Bozhou city, China between 2005 and 2015 and provide scientific basis for the prevention, control and elimination of measles. METHODS Cases of measles derived from the China Information System for Disease Prevention and Control, and demographic data were obtained from the Public Security Bureau of Bozhou city. RESULTS Among the 2934 cases, the average annual incidence of measles was 45.934 (per 1,000,000 persons) and no death occurred. The incidence of males was higher than females (Z = 10.794, p < 0.05). Scattered children accounted for 63.2% (1854/2934) in occupation distributing. In terms of immunization history of cases, 57.5% had 0 doses, 15.0% had one dose, 7.5% had two doses and others were uncertain. CONCLUSIONS Our study has investigated the epidemiological characteristics of measles in Bozhou City. To eventually eliminate measles in Bozhou city, improving measles vaccination coverage and quality of routine immunization services were important.

Abstract
We investigated the relationships between core self-evaluation (CSE), regulatory emotional self-efficacy (RESE), and depressive symptoms. In the first of two mediation models that we proposed, we predicted that RESE would mediate the relationship between CSE and depressive symptoms,
and in the second model we proposed that CSE would mediate the relationship between RESE and depressive symptoms. Participants, who comprised 1,108 Chinese adolescents, completed surveys to assess their CSE, RESE, and depressive symptoms. Results showed that both models were a good fit to
the data after demographic variables were controlled. We offered insight into depressive symptoms during adolescence by demonstrating that cultivating adolescents' positive view of themselves and their self-efficacy in regulating emotion is conducive to reducing their depressive symptoms.

Abstract
This paper reports the residual dynamics of deltamethrin and detection method in Loincerae Japonicae Flos to provide scientific basis for safe and appropriate use of deltamethrin. A field experiment was conducted in Fengqiu, Henan Province China. The field plots were sprayed with deltamethrin at the recommended dose and a high dose, respectively, and a control was set up, totally being 3 treatments with 3 replications. The flowers were picked at 2 hours, 1, 2, 3, 4, 5, 7, 9, 11, 13 and 15 days after pesticide application and then dried. The residue of deltamethrin was determined by gas chromatography method with electron capture detector for the above samples. Results showed that recoveries of deltamethrin ranged from 76.4% to 86.9%,and the relative standard deviation was below 11%,Linearity was observed over a range of 5-500 μg•L ⁻¹ with correlation coefficient was 0. 999 2. The established method meets the requirements of pesticide residue analytical methods. The degradation of deltamethrin followed the first order dynamics. The residue dynamic equation of the high dose and recommended dose deltamethrin were C=5.992 2e-0.338t and C=1.536 9e-0.31t respectively, and the half-life of deltamethrin in Loincerae Japonicae Flos was 2.09-2.24 days, which indicates that deltamethrin is an easily degradable pesticide. It is concluded that deltamethrin should be used in aphids occurring period and the safety interval was more than 7 days to ensure the safety of Loincerae Japonicae Flos consuming.
