Abstract
Objective: To investigate the safety and influencing factors of ct-guided percutaneous lung biopsy in pneumoconiosis patients. Methods: The data of 63 patients with pneumoconiosis who underwent ct-guided percutaneous lung biopsy in our hospital were studied to analyze the incidence of complications and influencing factors of percutaneous lung biopsy. Results: 63 cases of pneumoconiosis patients received CT guided percutaneous lung biopsy. There were 29 cases of complications (46.03%) , including 20 pneumothorax (37.75%) , 12 bleeding (19.05%) , and 3 cases of liquid pneumothorax (4.76%) . The single factor chi square analysis showed that there were significant differences in age, depth of focus, puncture position and puncture times (P<0.05) , and there was significant difference between the occurrence of hemorrhage and age, type of focus, size of focus, and the location of puncture site (P<0.05) . The unconditional LogisticL multiple factor regression analysis showed that the depth of the lesion was an independent risk factor for concurrency pneumothorax, and the size of the lesion was an independent risk factor for bleeding. Conclusion: Complications of CT-guided percutaneous pulmonary biopsy are mainly pneumothorax and hemorrhage. Age, focus type, focus size, focus depth, puncture site, and puncture times are all the factors of complications.

Abstract
Objective: To evaluate the implementation effect of the Beijing Tobacco Control Regulation. Methods: An observational study was conducted in a multi-stage randomly selected sample of 93 restaurants in Dongcheng and Chaoyang districts, Beijing. Undercover visits to the restaurants were paid by investigators at lunch or dinner time. The incidence of smoking behavior and the posters of no-smoking signs were observed, waiters were interviewed about awareness of the regulation, and comparisons with the baseline data of 6 months before and 1 month after regulation implementation were made. Results: The pasting rate of no-smoking signs was 76.3%. The awareness of the regulation in the waiters surveyed was high. The incidence rate of smoking in restaurants (29.0%) was lower than that before the regulation implementation (36.7%), but it was significantly higher than that one month after regulation implementation (14.8%). No active interventions from the restaurant staff were observed when smoking occurred. The incidence of smoking in restaurants within commercial buildings (3.3%) was significantly lower than that in non-commercial buildings (41.3%), the difference was significant (P<0.05). Conclusions: The effect of the regulation weakened 3 years after implementation compared with that in 1 month after the implementation. The enforcement degree of the regulation was conflicted with pasting rate of no-smoking signs and the regulation awareness level in waiters in restaurants in Dongcheng and Chaoyang districts.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) remains a clinical challenge due to its poor prognosis. Therefore, the early diagnosis of PDAC is extremely important for achieving a cure. MicroRNAs (miRNAs) could serve as a potential biomarker for the early detection and prognosis of PDAC. In this work we analyzed plasma samples from healthy persons and PDAC patients to assess differential miRNA expression profiles by next generation sequencing technology and bioinformatics analysis. In this way, 165 mature miRNAs were found to be significantly deregulated in the patient group, of which 75 and 90 mature miRNAs were up- and down-regulated compared with healthy individuals, respectively. Furthermore, 1029 novel miRNAs were identified. In conclusion, plasma miRNA expression profiles are different between healthy individuals and patients with PDAC. These data provide a possibility for use of miRNA as diagnostic and prognostic biomarkers of PDAC.

Abstract
INTRODUCTION Approximately 5%-20% of reproductive women suffer from polycystic ovary syndrome (PCOS). Auricular points acupressure (AA) may serve as alternative management for PCOS for its benefits in both physical and psychological well-being. However, the effects of AA for insulin resistance (IR) in overweight/obese PCOS women have not been confirmed. METHODS AND ANALYSIS The present study is designed as a randomised, placebo-controlled pilot trial to evaluate the effectiveness and safety of AA in treating IR in women with PCOS. A total of 60 eligible PCOS subjects will be randomised into an intervention group (AA group) and a control group (sham AA group) in a ratio of 1:1. Magnetic beads will be taped to the auricular points by the same senior acupuncture specialist from the First Affiliated Hospital, Heilongjiang University of Chinese Medicine. The treatment will last for 12 weeks. Primary outcome measure will be changes in homeostasis model assessment of IR between baseline and after 3 months of AA/sham AA treatment. Secondary outcomes include hormonal profile, weight, waist/hip circumference, body mass index, blood pressure, Ferriman-Gallwey score, acne and the assessment of health-related quality of life. Outcome measures are collected at baseline and the end of treatment visit. ETHICS AND DISSEMINATION The protocol has been approved by the ethics committee of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine (HZYLLKY201800301). Written informed consent will be obtained from all participants. The results will be disseminated through peer-reviewed journals for publications. TRIAL REGISTRATION NUMBER NCT03546595; Pre-results.

Abstract
The change in mean-square nuclear charge radii δ⟨r^{2}⟩ along the even-A tin isotopic chain ^{108-134}Sn has been investigated by means of collinear laser spectroscopy at ISOLDE/CERN using the atomic transitions 5p^{2} ^{1}S_{0}→5p6 s^{1}P_{1} and 5p^{2} ^{3}P_{0}→5p6s ^{3}P_{1}. With the determination of the charge radius of ^{134}Sn and corrected values for some of the neutron-rich isotopes, the evolution of the charge radii across the N=82 shell closure is established. A clear kink at the doubly magic ^{132}Sn is revealed, similar to what has been observed at N=82 in other isotopic chains with larger proton numbers, and at the N=126 shell closure in doubly magic ^{208}Pb. While most standard nuclear density functional calculations struggle with a consistent explanation of these discontinuities, we demonstrate that a recently developed Fayans energy density functional provides a coherent description of the kinks at both doubly magic nuclei, ^{132}Sn and ^{208}Pb, without sacrificing the overall performance. A multiple correlation analysis leads to the conclusion that both kinks are related to pairing and surface effects.

Abstract
Background Gemcitabine (2′,2′-difluoro-2′-deoxycytidine;dFdC) is a first-line chemotherapy drug for pancreatic cancer. Recently, a synergistic anti-tumor treatment of dFdC and hyperthermia has achieved good clinical results, but there are few reports on the molecular mechanism influenced by hyperthermia. This study is an initial exploration of the effects of hyperthermia on changes in the concentration of dFdC and its metabolites in pancreatic cancer cells. The aim is to provide a theoretical basis for clinical detection and pharmacokinetic research. Methods PANC-1 cells at logarithmic growth phase were used as the experimental object. The MTT assay was performed to determine the half maximal inhibitory concentration (IC50) of dFdC. After PANC-1 cells were cultured in DMEM medium containing IC50dFdC and treated with hyperthermia at 41 °C or 43 °C, changes in the concentration of dFdC, 2′,2′-difluorodeoxyuridine (dFdU) and difluorodeoxycytidine triphosphate (dFdCTP) in the cells were tested using an optimized reverse phase high-performance liquid chromatography (RP-HPLC) protocol. Results We found that 41 °C and 43 °Chyperthermia gave rise to a decrease in dFdC and dFdU content. At 41 °C, the levels respectively fell to 9.28 and 30.93% of the baseline, and at 43 °C, to 24.76 and 57.80%, respectively. The dFdCTP content increased by 21.82% at 41 °C and 42.42% at 43 °C. Conclusion The two heat treatments could alter the mechanism of dFdC metabolism in PANC-1 cells. The effect of 43 °C hyperthermia is more significant. Our observations may be instrumental to explaining the higher anti-tumor efficacy of this combination therapy.

Abstract
INTRODUCTION Dietary exposure monitoring within populations is reliant on self-reported measures such as Food Frequency Questionnaires and diet diaries. These methods often contain inaccurate information due to participant misreporting, non-compliance and bias. Urinary metabolites derived from individual foods could provide additional objective indicators of dietary exposure. For biomarker approaches to have utility it is essential that they cover a wide-range of commonly consumed foods and the methodology works in a real-world environment. OBJECTIVES To test that the methodology works in a real-world environment and to consider the impact of the major sources of likely variance; particularly complex meals, different food formulations, processing and cooking methods, as well as the dynamics of biomarker duration in the body. METHODS We designed and tested a dietary exposure biomarker discovery and validation strategy based on a food intervention study involving free-living individuals preparing meals and collecting urine samples at home. Two experimental periods were built around three consecutive day menu plans where all foods and drinks were provided (n = 15 and n = 36). RESULTS The experimental design was validated by confirming known consumption biomarkers in urinary samples after the first menu plan. We tested biomarker performance with different food formulations and processing methods involving meat, wholegrain, fruits and vegetables. CONCLUSION It was demonstrated that spot urine samples, together with robust dietary biomarkers, despite major sources of variance, could be used successfully for dietary exposure monitoring in large epidemiological studies.

Abstract
BACKGROUND AND AIMS Potential associations of vegetarian diet patterns with fasting insulin (FI) and insulin sensitivity remain unclear. We aimed to investigate whether vegetarian diets were associated with FI and insulin sensitivity in a cross-sectional study in Chinese vegetarians and matched omnivores and then to test whether it is independent of body mass index (BMI). METHODS AND RESULTS This study included 279 vegetarians (73 vegans, 206 lacto-ovo-vegetarians) and 279 age- and sex-matched omnivores. Fasting blood glucose (FG) and FI concentrations were measured, and β-cell function (HOMA-β) and insulin resistance index (HOMA-IR) were used to evaluate insulin sensitivity. All blood glucose and insulin sensitivity indices were naturally log-transformed, and multiple-linear regression was used to determine the association between vegetarian diet patterns and insulin sensitivity after adjusting for confounders including BMI, visceral fat area, physical activity, sedentary time, income, alcohol consumption, and daily dietary intakes of macronutrients. Compared to omnivores, both vegan diet [β = -0.25, 95% CI: (-0.38, -0.14)] and lacto-ovo-vegetarian diet [β = -0.10, 95% CI: (-0.18, -0.01)] were negatively associated with HOMA-IR after adjusting for BMI. Vegan diet remained negatively associated with FI [β = -0.16, 95% CI: (-0.30, -0.01)] and HOMA-IR [β = -0.17, 95% CI: (-0.32, -0.03)] after adjusting for all confounders. CONCLUSION Vegetarian diet, especially vegan diet, is negatively associated with FI and IR, independent of BMI.

Abstract
Five patients with primary malignancies in the pterygopalatine fossa (PPF) and infra temporal fossa (ITF) were enrolled in this retrospective study between January 2012 and January 2018. After malignancies proven by biopsy and evaluation with CT and MRI scan, all patients received modified maxillary swing (MMS) approach for extirpation of malignant tumors in the PPF and ITF under general anesthesia. En bloc resection with wide surgical margins was successfully performed in all cases. Negative margins were observed in 4 cases and positive margins were found in one patient with adenoid cystic carcinoma who received postoperative radiotherapy. The most common complication was facial numbness. During the follow-up period (range 12 to 57 months), one patient suffered from recurrence while others did not. The advantages of MMS include wide surgical field, full exposure and easy manipulation. The MMS approach is expected to become an standard method for monobloc resection of malignancies in the PPF and ITF.

Abstract
Background Accumulating evidence suggests that the AKT/mTOR pathway plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) through activating T cells, and there are few studies looking into the role of microRNA (miRNAs) in the mechanism. We first found that miR-633 expression in CD4+T cells of SLE patients was significantly reduced. Objective To investigate the role of miR-633 in the AKT/mTOR pathway in lupus CD4+T cells. Methods Samples of 17 SLE cases and 16 healthy controls were collected to detect the expression of miR-633, AKT1, mTOR mRNA and proteins by quantitative polymerase chain reaction (qPCR) and Western-blot, respectively. To determine whether AKT1 is a direct target of miR-633, a luciferase assay was performed. In vitro, AKT1 siRNA, miR-633 mimics/inhibitors or negative controls were transfected to Jurkat cells, human primary CD4+T cells and lupus CD4+T cells. RNA and proteins were extracted after 48 h, and levels of AKT/mTOR pathway markers and downstream multiple cytokines were detected by qPCR or Western-blot. Results In SLE patients, the miR-633 levels in CD4+T cells were significantly decreased and negatively correlated with SLEDAI. AKT1, mTOR mRNA and proteins were all up-regulated. The degree of downregulation of miR-633 was correlated negatively with AKT1 mRNA. The luciferase assay proved that AKT1 is a direct target of miR-633. In Jurkat and lupus CD4+T cells, overexpression of miR-633 could result in lower levels of AKT1 and mTOR. Inhibition of miR-633 expression in primary CD4+T cells caused reverse effects, and protein levels of p-AKT, p-mTOR, and p-S6RP increased. Moreover, among various cytokines, the expression of IL-4, IL-17, and IFN-γ mRNA was raised. Conclusion Our study suggests that miR-633 deletion can activate the AKT/mTOR pathway by targeting AKT1 to participate in the pathogenesis of SLE.

Abstract
RESEARCH QUESTION What is the association between hyperhomocysteinaemia (HHCY), metabolic syndrome, and reproductive outcomes among women with polycystic ovary syndrome (PCOS). DESIGN A secondary analysis of PCOSAct with 21 sites in China. A total of 1000 women with PCOS were enrolled; 936 women with baseline homocysteine (HCY) were analysed. RESULTS Higher HCY was associated with higher body mass index, free testosterone and lower FSH, fasting glucose (P < 0.001; P < 0.001; P = 0.005; P < 0.001) and ovulation rate among all participants (OR 0.59, 95% CI 0.41 to 0.86; OR 0.57, 95% CI 0.39 to 0.83 tertiles 2 and 3 versus tertile 1, respectively). The HHCY group had lower oestradiol and higher free testosterone (P = 0.04; P < 0.001) than the controls. In the metabolic syndrome group, LH, LH-FSH ratio and sex hormone-binding globulin were lowest in the metabolic syndrome group (all P < 0.001). In the HHCY group, ovulation rate decreased and the second or third trimester pregnancy loss rate increased compared with controls (OR 1.678, 95% CI 1.04 to 2.70; OR 0.03, 95% CI 0.00 to 0.42) with treatment adjustment. Compared with the controls, ovulation, conception, pregnancy, second or third trimester pregnancy loss and live birth rates were statistically lower in the metabolic syndrome group after adjusting treatment (OR 1.76, 95% CI 1.15 to 2.70; OR 1.75, 95% CI 1.15 to 2.65; OR 2.09, 95% CI 1.27 to 3.44; OR 0.02, 95% CI 0.00 to 0.33; OR 2.42 95% CI 1.42 to 4.10), and pregnancy, pregnancy loss and live birth rates remained significantly different after adjusting for treatment and sex-hormone factors (OR 1.77, 95% CI 1.05 to 2.99; OR 0.14, 95% CI 0.02 to 0.82; OR 2.02, 95% CI 1.16 to 3.50). CONCLUSIONS In women with PCOS, HHCY contributes to increased pregnancy loss and reduced ovulation, and metabolic syndrome was related to defects in ovulation, conception, pregnancy, pregnancy loss and live birth, indicating that the two conditions lead to defects at various reproductive stages.

Abstract
AIMS To select apple rootstocks that are tolerant to low nitrogen and reveal the relationship between the rhizosphere bacterial communities and the low nitrogen tolerance of the apple rootstock. METHODS AND RESULTS In total, 235 lines of hybrids of Malus robusta Rehd. × M.9 with low nitrogen stress were cultivated in pots in a greenhouse equipped with a drip irrigation system, and growth characteristics, photosynthesis traits and mineral elements were monitored. The bacterial community structure of the rhizosphere from different rootstocks was determined via Illumina MiSeq sequencing. This study selected three low nitrogen-tolerant (NT) lines that had higher nitrogen concentration, and higher photosynthesis rate than the three low nitrogen-sensitive (NS) lines. The bacterial community structure significantly differed (P ≤ 0·001) among the rootstocks. The bacterial phyla Proteobacteria and Actinobacteria were the dominant groups in the rhizosphere and presented higher abundance in the NT rhizosphere. The N concentration in the apple rootstocks exhibited highly positive Pearson correlations with the bacterial genera Sphingomonas, Pseudoxanthomonas, Bacillus and Acinetobacter, and negative correlations with the bacterial genera Pseudarthrobacter and Bradyrhizobium. CONCLUSIONS This study showed that investigated rootstocks achieved increased nitrogen concentration by enhancing their photosynthetic production capacity and shaping their rhizobacteria community structure. SIGNIFICANCE AND IMPACT OF THE STUDY The findings provide a basis for studying the mechanisms of resistance to low nitrogen stress in apple rootstocks. Based on these beneficial bacteria, microbial inoculants can be developed for use in sustainable agricultural and horticultural production.

Abstract
BACKGROUND Dyslipidemia is commonly characterized by the abnormal quantity and quality of lipids in plasma, which is strongly associated with an increased risk of cardiovascular disease and also a major cause of morbidity and even leads to mortality. In China and East Asia, Chinese herbal medicine has been widely used to treat diverse diseases for thousands of years. As an important means of traditional Chinese medicine treatment, Chinese herbal medicine plays a more important role in the treatment of dyslipidemia. The aim of this study is to assess the efficacy and safety of Chinese herbal medicine for dyslipidemia. METHODS Seven electronic databases (included The Cochrane Library, MEDLINE, Embase, CNKI, VIP, CBM, and WANGFANG) will be searched regardless of publication date or language. Randomized controlled trials will be included if they recruited participants with dyslipidemia for assessing the effect of Chinese herbal medicine vs control (placebo, no treatment, and other therapeutic agents). Primary outcomes will include serum lipid and advent events. Two authors will independently scan the articles searched, extract the data from articles included, and assess the risk of bias by Cochrane tool of risk of bias. Disagreements will be resolved by discussion among authors. All analysis will be performed based on the Cochrane Handbook for Systematic Reviews of Interventions. Dichotomous variables will be reported as risk ratio or odds ratio with 95% confidence intervals (CIs) and continuous variables will be summarized as mean difference or standard mean difference with 95% CIs. RESULTS This review will be to assess the efficacy and safety of Chinese herbal medicine for dyslipidemia. CONCLUSIONS Our findings will assist clinicians and health professionals make clinical decisions regarding dyslipidemia prevention, and promising way for prevention and treatment of patients with dyslipidemia. ETHICS AND DISSEMINATION This study is a protocol for systematic review of Chinese herbal medicine as a treatment of dyslipidemia. This review will be published in a journal and disseminated in print by peer-review. SYSTEMATIC REVIEW REGISTRATION PROSPERO (CRD42018085556).

Abstract
BACKGROUND Pain is one of the major adverse clinical outcomes of cesarean section (CS). In the past few years, researchers and physicians have been optimizing post-operative analgesic modalities, but the results are still undesirable for the parturient. The cytochrome P-450 3A4 (CYP3A4) gene has been reported to contribute significantly to human liver microsomal oxidation of sufentanil and alfentanil. METHODS We detected the frequency of CYP3A4 mutant allele, which is associated with the metabolism of diverse drugs, including opioids used for anesthesia. We then investigated the correlation between sufentanil (an opioid analgesic) consumption and CYP3A4 genetic polymorphism. RESULTS We found the frequency of the CYP3A4∗1G (the mutant form of CYP3A) variant allele to be 0.279 in 71 parturients undergoing cesarean section and 137 age-matched parturients with vaginal delivery. Interestingly, the parturients with homozygous CYP3A4∗1G showed less sufentanil consumption compared with those having the wild-type genotype. CONCLUSION In summary, we found a correlation between CYP3A4 genetic polymorphism and sufentanil consumption. This might be helpful for optimizing the anesthesia strategies and reducing their side effects.

Abstract
Objective: To investigate the change in peripheral nervous conduction velocity in patients with occupational chronic mercury poisoning and related influencing factors. Methods: From February 2011 to December 2014, urinary mercury examination and neural electromyography were performed for 104 patients with occupational chronic mercury poisoning. The data on age, type of work, working years of mercury exposure, and past medical history were collected, and peripheral nervous conduction velocity and its correlation with age, working years of mercury exposure, and urinary mercury concentration were analyzed. Results: All the 104 patients with occupational chronic mercury poisoning had a mean of 45.37±9.82 years, median (P(25), P(75)) working years of 7 (3, 11) , and a median (P(25), P(75)) urinary mercury concentration of 88.50 (56.25, 163.03) μg/g Cr. The major clinical manifestations of peripheral nerve injuries were numbness of extremities (20.2%) , hypopselaphesia/hypalgesia or hyperpselaphesia/hyperalgesia (9.6%) , and bone/muscle pain in the extremities (6.7%) . Neural electromyography showed an increase in denervation potential (fibrillation potential or positive sharp wave) and a detection rate of abnormal peripheral nervous conduction velocity as high as 65.4%. The patients with an older age and more working years had a higher incidence rate of abnormal sensory conduction velocity of the ulnar nerve. There were significant reductions in motor and sensory conduction velocities of the median nerve, motor and sensory conduction velocities of the ulnar nerve, motor conduction velocity of the common peroneal nerve, and the sensory conduction velocity of the superficial peroneal nerve (P<0.05) , with the increase in urinary mercury concentration. Conclusion: Patients with occupational mercury poisoning have a high rate of abnormal neural electromyographic findings, which can be used as an important method for early identification of chronic peripheral nerve injuries induced by mercury poisoning. The degree of peripheral nerve injuries increases with the increasing time of mercury exposure and urinary mercury concentration.

Abstract
Objective: To investigate the clinical features of pneumoconiosis complicated with pulmo-nary emphysema. Methods: selected 868 patients with pneumoconiosis were selected from December 2015 to December 2016 in Hunan occupational disease prevention and treatment hospital. Collected the results of high-resolution spiral CT, arterial blood gas, ECG, pulmonary function and MRC score. The subjects were divided into pneumoconiosis complicated with pulmonary emphysema group and simple pneumoconiosis group accord-ing to the results of HRCT. The smoking, MRC score, pulmonary function, blood gas and complications were compared. Results: A total of 868 patients were enrolled in the study. Emphysema 232 people, accounting for 26.73%. The incidence of emphysema in the first phase of pneumoconiosis was 12.69%, and the incidence rate of emphysema in pneumoconiosis was 17.03%, The incidence of three Stage pneumoconiosis was highest, up to 60.76%, the incidence of emphysema increased with the increase of stages of pneumoconiosis (P=0.000) .The smoking index of pneumoconiosis combined with emphysema group was significantly higher than that of simple pneumoconiosis group (P<0.01) . The MRC score of pneumoconiosis complicated with pulmonary em-physema group was higher than that of simple pneumoconiosis group (P=0.000) . In pneumoconiosis complicat-ed with pulmonary emphysema group the FEV(1.0)%, FVC%, FEV(1.0)/FVC, DLCO%, oxygen partial pressure were significantly lower than that of simple pneumoconiosis group (P≤0.05) . The combined rate of Bullae of lung in pneumoconiosis complicated with pulmonary emphysema group was higher than that of simple pneumo-coniosis group (P<0.01) . Conclusion: pneumoconiosis stage and smoking. Patients with pneumoconiosis com-plicated with pulmonary emphysema had heavier breathing difficulties, more serious pulmonary function and active endurance, the degree of hypoxia is more serious, and had a higher incidence of complications. The pul-monary function of pneumoconiosis complicated with pulmonary emphysema is not consistent with the typical CPFE.

Abstract
To detect syntaxin-binding protein 1 (STXBP1) mutations in Chinese patients with early onset epileptic encephalopathy (EOEE) of unknown etiology. Targeted next-generation sequencing was used to identify STXBP1 mutations in 143 Chinese patients with EOEE of unknown etiology. A filtering process was applied to prioritize rare variants of potential functional significance. Then Sanger sequencing was employed to validate the parental origin of the variants. Detailed clinical and genetic data were collected for 9 STXBP1-positive patients. Eight de novo heterozygous STXBP1 mutations were identified in 9 patients; 5 were novel mutations (c.1155delC, c.1030-1G>A, c.217G>C, c.268G>C, c.1480_1481 insT) and 3 were previously reported (c.1216C> T, c.1217G>A [2 cases], c.875G>A). Two patients had Ohtahara syndrome and 1 had West syndrome at onset, whereas the other 6 presented with EOEE that did not fit a specific recognized epilepsy syndrome. Six of these patients later evolved to West syndrome. All but 2 cases were prescribed more than 2 antiepileptic drugs (AEDs) plus other regimens. Four subjects showed good responses to levetiracetam (LEV) alone or in combination with other AEDs, and one case (1/3) achieved complete freedom from seizures with a ketogenic diet (KD). All patients exhibited severe to profound global developmental delay. Five novel heterozygous de novo STXBP1 mutations were discovered in patients with EOEE from China. STXBP1 mutational analysis should be performed in cases of EOEE of unknown etiology. LEV as monotherapy or adjunctive therapy with other regimens, as well as KD should be considered for management of this patient group.
