Abstract
OBJECTIVE To analyze the hospitalization cost and its influencing factors of imported malaria patients in Guangxi Zhuang Autonomous Region and Yunnan Province, so as to provide insights into the evaluation of the economic burden due to imported malaria, and the guiding of malaria control and the rational allocation of medical resources. METHODS The data pertaining to the hospitalization costs of imported malaria patients admitted to Shanglin County People's Hospital in Guangxi Zhuang Autonomous Region during the period from January 1 through December 31, 2019, and Tengchong Municipal People's Hospital in Yunnan Province from January 1, 2015 to December 31, 2019, were collected, and the epidemiological data of these imported malaria patients were extracted from the Information Management System for Parasitic Diseases Control and Prevention, China. The composition of the hospitalization expenses was analyzed using a descriptive method. In addition, the factors affecting the hospitalization expenses of imported malaria patients were identified using a univariate analysis and a recursive system model. RESULTS A total of 206 imported malaria patients were included in this study, including 194 men (94.17%) and 12 women (5.83%). The mean length of hospital stay was 5.00 days per patient and the median hospitalization expenses were 2 813.07 Yuan per time, in which the expenses for laboratory examinations were the highest (45.31%, 1 274.62/2 813.07). Univariate analysis showed that hospital (z = 5.43, P < 0.01), type of malaria (χ2 = 34.86, P < 0.01) and type of payment (χ2 = 7.72, P < 0.05) were factors affecting the hospitalization expenses of imported malaria patients. Recursion system modeling revealed that the total effects on hospitalization expenses of imported malaria patients included length of hospital stay (0.78), selection of hospital (0.34), basic medical insurance for urban and rural residents (0.19), new rural cooperative medical care (0.17), Plasmodium falciparum malaria (0.15), gender (0.11) and P. vivax malaria (0.09). CONCLUSIONS The hospitalization expenses of imported malaria patients are affected by multiple factors in Guangxi Zhuang Autonomous Region and Yunnan Province, in which the length of hospital stay is the most predominant influencing factor. A reduction in the length of hospital stay is effective to decrease the hospitalization expenses of imported malaria patients.

Abstract
A tangential hard x-ray (HXR) diagnostic on the newly constructed ENN XuanLong-50 (EXL-50) spherical tokamak for fast electron emission studies is presented. The HXR detection system consists of a symmetrical CdZnTe semiconductor detector array with a spectral sensitivity range of 20-300 keV. 25 channels have been designed on the 270° horizontal vacuum port with 12 sight lines to observe the forward emission, 12 sight lines to observe the backward emission of fast electrons, and 1 for viewing the central. Currently, ten channels have been in operation in the EXL-50 experiments. The systems are designed to measure the x-ray spectra for the estimation of fast electron temperature and electron velocity distribution in the EXL-50 experiment, which will be useful for understanding the dynamics of fast electrons generated by electron cyclotron resonance heating, for plasma instability and transport studies and for the analysis of plasma heating efficiency.

Abstract
BACKGROUND Germinoma is a type of germ cell tumor that most frequently arises in the midline axis of the brain. Impaired vision is a clinical manifestation of germinnoma. Although rare, intracranial germinoma seeding to the perioptic arachnoid space is one cause of visual acuity decrease.
CASE SUMMARY An 11yearold girl who presented with polyuria and polydipsia and subsequently developed diminution of vision. Imaging showed bilateral heterogeneous enhancement of the optic nerve sheaths and atrophy of the optic nerve, and transsphenoidal biopsy revealed a germinoma. The patient experienced poor visual recovery following chemotherapy and radiotherapy. Germinomas are rare and they are mostly identified in children and adolescents. The manifestations include diabetes insipidus, pituitary dysfunction, visual complaints, etc. The mechanisms that lead to visual loss include intracranial hypertension, compression of optic chiasma, and tumor invasion. A literature review was performed to summarize the cases with a tumor infiltrating the optic nerve. Most of the reported patients were adolescents and presented with anterior pituitary hormone deficiency. Enhancement of optic nerve sheaths and optic disc pallor could be identified in most of the cases. The purpose of this report is to provide awareness that in cases where a germinoma is associated with visual loss, though rare, perioptic meningeal seeding should be taken into consideration.
CONCLUSION The case report suggests that children with diabetes insipidus need a complete differential diagnosis.

Abstract
Objective: To analyze the antimicrobial resistance characteristics of 538 Neisseria meningitidis isolated from 2005 to 2019 in China. Method: Total of 538 Neisseria meningitidis strains collected from 30 provinces in China from 2005 to 2019. Antimicrobial susceptibility test were performed based on the standards of clinical and laboratory standardization association (CLSI) including 11 recommended antibiotics. Gradient diffusion method was used to detect the antibiotic sensitivity of Neisseria meningitidis. Results: All 538 strains were sensitive to azithromycin, meropenem, chloramphenicol, rifampicin and ceftriaxone. As to other six antibiotics, the antibiotics sensitivity rates were cefotaxime (97.4%, 524 strains), ampicillin (87.7%, 472 strains), penicillin (84.8%, 456 strains), minocycline (95.2%, 512 strains), ciprofloxacin (24.9%, 134 strains) and trimethoprim/sulfamethoxazole (11.2%, 60 strains) respectively. Conclusions: Neisseria meningitidis isolated from 2005-2019 in China were all sensitive to azithromycin, meropenem, chloramphenicol, rifampicin and ceftriaxone. It should highlight Neisseria meningitidis resistant to cefotaxime, ampicillin and penicillin. Ciprofloxacin and sulfamethoxazole are not recommended as the priority choice for clinical treatment and prophylactic medication.

Abstract
Objective: To study the efficacy and patient comfort of absorbable hemostatic powder after endoscopic sinus surgery (ESS). Methods: A total of 21 (17 males, 4 females) patients with an average age of 42(ranging from 18 to 65) underwent bilateral ESS for chronic rhinosinusitis(CRS) in Beijing Tongren Hospital, Capital Medical University between October 2015 and July 2019 were enrolled to compare the effect of absorbable hemostasis powder with Nasopore using an intrapatient control design. A randomized controlled trial was conducted in the left and right nasal cavities of the same patient. If hemostatic powder was applied in the experiment nasal cavity, the Nasopore was applied in the control nasal cavity. The mean preoperative sinus computed tomography (CT) score was 6.25. All patients competed for symptom diaries using a visual analog scale (VAS, score out of 10) at baseline, through 1, 7, 14 and 30 days. Outcomes including bleeding, facial pain, nasal obstruction, nasal discharges using VAS were recorded separately for both sides. Postoperative endoscopic scores were also investigated. SPSS 22 and Graphpad prism 8.0 statistical softwares were used for the analysis. Paired t-test or nonparametric test was used between the test side and the control side. The difference was statistically significant (P<0.05). Results: The bleeding score and total nasal symptom VAS scores at postoperative days (POD) 1, 7, 14 and 30 were not significantly different(t=1.341, 0.552, 0.631, 0.158, all P>0.05;t=0.944, 1.471, 1.612, 2.251, all P>0.05). There was no significant difference between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of each nasal symptom VAS scores(all P>0.05). On POD 1, 7 and 14, the packing material degeneration scores of the absorbable hemostasis powder side were significantly lower than those of the Nasopore side [(1.33±0.21)vs(2.00±0.00),(0.38±0.18) vs (1.95±0.22), 0 vs (1.80±0.13), all P<0.01]. There were significant differences between absorbable hemostasis powder and Nasopore side on POD 1, 7, 14 and 30 in terms of endoscopic scores (edema, crusting, discharges, scar, polyps and material degeneration, t=3.07, 7.00, 6.41, 2.69, all P<0.05). Conclusions: The absorbable hemostasis powder and Nasopore has similar postoperative hemostasis effect. The absorbable hemostasis powder is rapidly cleared and without negative effects on mucosal wound healing 14 days postoperatively.

Abstract
BACKGROUND The mechanisms of bone fragility in type 1 diabetes (T1D) are not fully understood. Whether glucagon-like peptide-1 receptor (GLP-1R) agonists could improve bone quality in T1D context also remains elusive. AIMS We aimed to explore the possible mechanisms of bone loss in T1D and clarify whether liraglutide has effects on bone quality of T1D mice using transcriptomics. METHODS Female streptozotocin-induced diabetic C57BL/6J mice were randomly divided into four groups and received the following treatments daily for 8 weeks: saline as controls, insulin, liraglutide, and liraglutide combined with insulin. These groups were also compared with non-STZ-treated normal glucose tolerance (NGT) group. Trunk blood and bone tissues were collected for analysis. Three tibia from each of the NGT, saline-treated, and liraglutide-treated groups were randomly selected for transcriptomics. RESULTS Compared with NGT mice, saline-treated T1D mice manifested markedly hyperglycemia and weight loss, and micro-CT revealed significantly lower bone mineral density (BMD) and deficient microarchitectures in tibias. Eight weeks of treatment with liraglutide alone or combined with insulin rescued the decreased BMD and partly corrected the compromised trabecular microarchitectures. Transcriptomics analysis showed there were 789 differentially expressed genes mainly mapped to osteoclastogenesis and inflammation pathways. The RT-qPCR verified that the gene expression of Trem2, Nfatc1, Trap, and Ctsk were significantly increased in the tibia of T1D compared with those in the NGT group. Liraglutide treatment alone or combined with insulin could effectively suppress osteoclastogenesis by downregulating the gene expression of Trem2, Nfatc1, Ctsk, and Trap. CONCLUSIONS Taken together, increased osteoclastogenesis with upregulated expression of Trem2 played an important role in bone loss of T1D mice. Liraglutide provided protective effects on bone loss in T1D mice by suppressing osteoclastogenesis.

Abstract
In the present study, we analyzed the effects of Glycyrrhiza polysaccharide (GCP) on growth performance, serum antioxidant capacity, and biochemistry of broilers. A total of 600, one-day-old AA broilers randomly divided into 5 treatment groups with 6 replicate pens of 20 birds per cage received dietary supplementation with GCP (0, 200, 500, 1,000, and 1,500 mg/kg) for 42 d. The supplementation of GCP linearly decreased (P < 0.05) feed conversion rate on day 22 to 42. Dietary supplementation with GCP reduced (P < 0.05) serum total cholesterol on day 21 and 42 and linearly improved (P < 0.05) albumin and high-density lipoprotein cholesterol. Dietary supplementation with 1,000 or 1,500 mg/kg GCP significantly increased (P < 0.05) serum total superoxide dismutase (T-SOD) activity on day 21 and 42 and reduced (P < 0.05) serum malondialdehyde content on 21 d. Dietary supplementation with 1,000 or 1,500 mg/kg GCP significantly improved (P < 0.05) interleukin-1β (IL-1β) and interferon-γ (IFN-γ) expressions in liver on day 21 and 42. At the end of the experiment, we randomly selected 20 broilers from 3 treatment groups (0, 1,000, and 1,500 mg/kg), respectively, to perform an lipopolysaccharide (LPS)-induced acute stress experiment. The 60 broilers were divided into 6 treatment groups with 10 birds per cage. The experiment was designed as a 3 × 2 factorial arrangement with GCP (0, 1,000, or 1,500 mg/kg) and LPS (injection of saline or 1 mg/kg body weight) levels as treatments. When the grouping was finished, the broilers were immediately intraperitoneally injected with LPS or normal saline. Six hours after challenged, serum antioxidant and liver immunity were analyzed. The results showed that dietary GCP prevented LPS-induced reductions in T-SOD activity and increases in malonaldehyde content (P < 0.05). Also, dietary GCP supplementation mitigated the LPS-induced increase in IL-1β and IFN-γ in the liver. Supplementation with 1,500 mg/kg GCP showed the most optimal effect in broilers. GCP has the potential to be used as feed additive in broilers.

Abstract
Intestinal epithelial cells (IEC) act as an important intestinal barrier whose function can be impaired upon induction by hypoxia. Although intestinal barrier injuries are preventable by milk-derived exosomal microRNAs (miRNAs), the underlying mechanism remains poorly understood. This study aimed to characterize the effect of yak and cow milk-derived exosomal miRNA on the barrier function of IEC-6 under hypoxic conditions, and explore the mechanism of yak milk exosomal miRNA to relieve the hypoxia stress. First, by Illumina HiSeq 2500 (Illumina Inc., San Diego, CA) sequencing, the miRNA expression was systematically screened, and differential expression of 130 miRNAs was identified with 51 being upregulated and 79 downregulated in yak and cow milk-derived exosomes. Furthermore, the top 20 miRNAs that had a relatively consistent high expression in yak milk exosome were identified, and bta-miR-34a was found to be an effective regulator for alleviating hypoxic injury of IEC-6. In vitro assay of the role of bta-miR-34a on survival of IEC-6 in hypoxia by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) confirmed its effectiveness to significantly increase IEC-6 survival up to 13% for 12 h, and up to 9.5% for 24 h. Investigation on the regulatory relationship between bta-miRNA-34a and the hypoxia-inducible factor/apoptosis signaling pathway provided insights into the possible mechanisms by which bta-miR-34a activated the hypoxia-inducible factor and apoptosis signaling pathway, thus promoting IEC-6 survival. The results of this study suggest an important relationship between miRNA expression and intestine barrier integrity, which facilitated further understanding of the physiological function of yak and cow milk exosomal miRNAs, as well as mechanisms of hypoxia-driven epithelial homeostasis.

Abstract
Objective: To identify the risk factors of non-sentinel lymph node (nSLN) metastasis in breast cancer patients with 1~2 positive axillary sentinel lymph node (SLN) and construct an accurate prediction model. Methods: Retrospective chart review was performed in 917 breast cancer patients who underwent surgery treatment between 2002 and 2017 and pathologically confirmed 1-2 positive SLNs. According to the date of surgery, patients were divided into training group (497 cases) and validation group (420 cases). A nomogram was built to predict nSLN metastasis and the accuracy of the model was validated. Results: Among the 917 patients, 251 (27.4%) had nSLN metastasis. Univariate analysis showed tumor grade, lymphovascular invasion (LVI), extra-capsular extension (ECE), the number of positive and negative SLN and macro-metastasis of SLN were associated with nSLN metastasis (all P<0.05). Multivariate Logistic regression analysis showed the numbers of positive SLN, negative SLN and macro-metastasis of SLN were independent predictors of nSLN metastasis (all P<0.05). A nomogram was constructed based on the 6 factors. The area under the receiver operating characteristic curve was 0.718 for the training group and 0.742 for the validation group. Conclusion: We have developed a nomogram that uses 6 risk factors commonly available to accurately estimate the likelihood of nSLN metastasis for individual patient, which might be helpful for radiation oncologists to make a decision on regional nodal irradiation.

Abstract
Objective: To evaluate the incidence of early cardiac injury in patients with left-sided breast cancer receiving hypofractionated radiotherapy after breast conserving surgery, and to investigate the correlation between cardiac injury and hypofractionated radiotherapy dose. Methods: We prospectively enrolled 103 breast cancer patients who received whole breast with or without regional nodal irradiation after breast conserving surgery using either deep inspiration breath-hold (DIBH) or free breathing (FB) radiotherapy technique. Cardiac examinations that included N-terminal pro-B-type natriuretic peptide (NT-proBNP), electrocardiogram, and myocardial perfusion imaging were performed routinely before and after radiotherapy. The effects of heart dose, systemic therapy and individual factors (Framingham score) on the incidence of cardiac events were analyzed. Results: The median age was 48 years. The mean dose (Dmean) of the heart, left anterior descending coronary artery (LAD), left ventricular (LV), and right ventricular (RV) were 4.0, 16.9, 6.3, and 4.4 Gy, respectively. With a median follow-up of 13.4 months, no patient had clinical cardiac abnormalities. The incidence rates of subclinical cardiac events at 1- 6- and 12-month were 23.5%, 31.6%, and 41.3%, respectively. The DIBH group had a lower mean dose, maximum dose, and V5-V40 in the heart, LAD, LV, and RV than the FB group (P<0.001). Univariate analysis showed an increased incidence of subclinical cardiac events with heart Dmean >4 Gy, LAD V40 > 20%, LV Dmean >6 Gy, RV Dmean >7 Gy, or cumulative doses of anthracycline or taxane > 300 mg/m(2) (All P<0.05). Anti-HER2 targeted therapy, endocrine therapy and Framingham score were not associated with the incidence of subclinical cardiac events (all P>0.05). Multivariate analysis demonstrated that Dmean of LV and RV were independently associated with the increased incidence of subclinical cardiac events. Conclusions: Early subclinical heart injury are found in patients with left-sided breast cancer after hypofractionated radiotherapy. The increased incidence of subclinical cardiac events after radiotherapy is positively associated with the cardiac radiation doses.

Abstract
Therapeutic targeting the protein-protein interaction (PPI) of Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and its main regulator, Kelch-like ECH-Associating protein 1 (Keap1) has been emerged as a feasible way to combat oxidative stress related diseases, due to the key role of Nrf2 in oxidative stress regulation. In recent years, many efforts have been made to develop potent Keap1-Nrf2 inhibitors with new chemical structures. Various molecules with diverse chemical structures have been reported and some compounds exhibit high potency. This review summarizes peptide and small molecule Keap1-Nrf2 inhibitors reported recently. We also highlight the pharmacological effects and discuss the possible therapeutic application of Keap1-Nrf2 inhibitors.

The duplicated reporting rate in same year was 37.21/10 000 (1 859/499 577), the duplicated reporting rate in other year was 39.87/10 000 (1 992/499 577) and the overall duplicated reporting rate increased year by year. The duplicated reporting rate in same institution was 33.59% (1 271/3 785) and the duplicated reporting rate by other institutions was 66.41% (2 514/3 785). Hospitals had the highest number of duplicated reporting (2 757), and community healthcare centers had the highest of duplicated reporting rate (281.27/10 000) (123/4 373). The reported incidence of brucellosis was 2.926 4/100 000 in 2017, the corrected incidence was 2.844 8/100 000 after removing the duplicated reporting, which was the maximum decrease from 2005 to 2017, the corrected incidence decreased by 2.79%. From 2005 to 2017, the average reported incidence of brucellosis in Xinjiang Uygur autonomous region was 14.712 0/100 000, and the corrected incidence was 14.060 0/100 000 after removing the duplicate reporting, with a decrease by 4.43%, the biggest decline in China. The average reported incidence of brucellosis in Ningxia Hui autonomous region was 13.987 1/100 000, and the corrected incidence of brucellosis was 13.662 2/100 000, with a decrease of 2.32%, ranking second in China. The reasons for duplicated reporting of brucellosis included repeated medical care seeking in same or different medical institutions in same year or other year, including the repeated medical care seeking in other areas. Conclusions: During 2005-2017, the number of duplicated reporting of brucellosis cases was on the rise in China. Hospital and community health service centers had highest case number and rate of duplicate reporting respectively, the duplicated reporting was mainly caused by re-reporting by other institutions or in other years. The duplicated reporting of brucellosis had greatly affected the accuracy of surveillance data of brucellosis in some provinces, such as Xinjiang and Ningxia. It is recommended to further strengthen brucellosis reporting management, improve data quality of NNDRS.

Abstract
Objective: To explore the MR characteristics of normal anatomy and injured peroneal tendon and the diagnostic value of MR in the peroneal tendon injuries. Methods: From February 2018 to December 2018, a total of 20 healthy volunteers (40 ankle joints) were selected, 10 males and 10 females, with an age range of 20-30 (26±3) years. Retrospective analyzed 62 patients with ankle sprain and peroneal tendon injuries confirmed by operation, 34 males and 28 females, with an age range of 14-78(41±14) years. All volunteers and patients underwent MR examination. The MRI characteristics of the normal anatomy of peroneal tendon were analyzed. The patients were classified according to the MR diagnostic criteria of injury. Then the MRI features of different types of injured peroneus longus tendon and peroneus brevis tendon were analyzed. At last, imaging findings were compared with surgical results. Results: The peroneal tendon of 20 healthy volunteers showed oval and elliptical band-like structures on T(1)WI and PD-FS sequences, with natural alignment, clear boundary and uniform low signal. The whole length of the peroneal tendon can't be displayed completely on the same imaging plane. It needed multi-dimensional observation combined with axial, coronal and sagittal directions. There were 62 cases of peroneal tendon injury, including 46 cases of peroneal tendon tear (7 cases of partial-thickness tear, 11.3% of the total injuries, 39 cases of full-thickness tear, 62.9% of the total injuries), 16 cases of peroneal tendon dislocation (15 cases of intrathecal dislocation, 24.2% of the total injuries, 1 case of extrathecal dislocation, 1.6% of the total injuries). In 7 cases of partial-thickness tear (4 cases of peroneus brevis tendon tear, 3 cases of peroneus longus tendon tear), MR showed irregular tendon shape and local continuity interruption. In 39 cases of full-thickness tear (31 cases of peroneus brevis tendon tear, 8 cases of peroneus longus tendon tear), MR showed that the tear was penetrated through the whole layer of tendon from dorsolateral side to plantar side of foot, and the range of tear was different. The torn tendon could be accompanied by tendinitis or effusion of tendon sheath; 15 cases of intrathecal dislocation (3 cases of type A, 12 cases of type B), MR findings of type A dislocation showed that the peroneus longus tendon was located in the deep part of the peroneus brevis tendon, MR findings of type B dislocation showed that the peroneus longus tendon was displaced into the longitudinal tear of peroneus brevis tendon. In 1 case of extrathecal dislocation (type Ⅲ), MR showed that the SPR and the attached cortex of lateral malleolus were avulsed together, and the peroneal tendon was displaced under the avulsed fracture piece. Conclusion: MR can accurately demonstrate the fine anatomical structure of peroneal tendon and the imaging features of injuries. It has important clinical application value for the early diagnosis and accurate treatment of peroneal tendon injuries.

Abstract
Objective: To explore the clinical characteristics and follow-up outcomes of a pedigree of maturity onset diabetes of the young (MODY) induced by a novel mutation of glucokinase (GCK). Methods: The clinical features and laboratory data of a pedigree diagnosed with GCK-MODY in Peking Union Medical College Hospital was analyzed. Genomic DNA was extracted, and Sanger sequencing was performed to detect the gene mutation of the family members. The proband and her father were followed up for 3 years. Wanfang and PubMed were used to search literatures on follow-up studies for treatment of GCK-MOYD. Results: Both the proband and her father were found to have a novel mutation on the GCK gene located in exo10 c.1348G.T (p. Ala450Thr). The proband was treated with diet and exercise control only. At the end of the follow-up, her fasting plasma glucose (FPG, 6.8 mmol/L), 2 h postprandial plasma glucose (2hPG, 7.4 mmol/L), and glycated hemoglobin (HbA1c, 6.3%) were all within the control targets. Additionally, the levels homeostasis model assessment of insulin resistance (HOMA-IR) tended to improved comparing to that at baseline (4.09 to 2.32), and glucose disposition index (DI) was improved compared with baseline (16.22 to 20.05). As to the proband's father, the treatment with insulin plus acarbose was converted to sulfonylureas monotherapy. His FPG and 2hPG mostly were within the target range, and the levels of HbA1c were significantly reduced by 0.5%-0.7% when compared to that at baseline. The HOMA-IR or islet beta cell function was comparable to those at baseline. Conclusions: Screening patients whose clinical performance meets GCK-MODY and their family members with proper genetic testing is of great importance to reduce misdiagnosis of GCK-MODY, so as to obtain a better glucose control without unnecessary over-treatment and protect islet beta cell function.

Abstract
Due to the flaws inherited in synchronicity, statistical association and survivor bias on variables under measurement, a common 'consensus' has been reached on "cross-sectiional studies (CSS) can lead to failure on causal inference". In this paper, under both causal thinking and diagram, the real and measured cross-sections are clearly defined that these two concepts only exist theoretically. In real CSS research, the temporal orders of measured variables are all non-synchronic, equivalent to the assumption that measurement variables are independent to each other, or there is no differentiated classification bias. Similar to cumulative case-control or historical cohort studies, both exposure and outcome that exist or occur before their measurements in cross-sectional studies, are actions of historical reconstruction or doing 'Archaeology'. One of the common preconditions for causal inference in such studies is that: there must be a causal relation between the measured variables and their historical counterparts. The measured variables are all agents of their corresponding real counterparts, and the temporal orders are not that important in causal inference. It is necessary to better understand the analytic role of the CSS.

Abstract
To investigate the early changes of peripheral blood leukocyte differential counts in patients with COVID-19. Ten patients with COVID-19 and 30 patients with other viral pneumonia (non-COVID-19) admitted to Shanghai Jiao Tong University Affiliated Sixth People's Hospital and Jinshan Branch Hospital from January 22 to February 17, 2020 were enrolled in this study. The differential counts of white blood cells were analyzed. Patients in COVID-19 group showed relatively lower absolute white blood cell (WBC) count 4.95(3.90,6.03)×10(9)/L, lymphocyte absolute count 1.20(0.98,1.50)×10(9)/L and eosinophil absolute count 0.01(0.01,0.01)×10(9)/L. Leukopenia developed in two patients(2/10), lymphocytopenia also in two patients(2/10). Seven over ten patients presented with eosinophil cytopenia. In non-COVID-19 group, absolute WBC count was 8.20 (6.78,9.03) ×10(9)/L (P<0.001), lymphocyte absolute count 1.75(1.20,2.53)×10(9)/L(P=0.036), eosinophil absolute count 0.02(0.01,0.03)×10(9)/L(P=0.05). Lymphocytopenia occurred in (16.7%) patients, eosinophil cytopenia in 16.7% patients too. In conclusion, leukopenia, lymphocytopenia and eosinophil cytopenia are more common in COVID-19 patients than those in non- COVID-19 patients.

Abstract
Pancreatic cancer is malignant and has a poor prognosis.At present, the treatment mode has changed from "Surgery First" to systemic therapy under multi-disciplinary team, but surgical resection is still the only way to cure pancreatic cancer. In systemic treatment of pancreatic cancer, the effect of postoperative adjuvant therapy is significant, and preoperative neoadjuvant therapy has gradually attracted widespread attention. Neoadjuvant therapy can improve the rate of R0 resection in patients with pancreatic cancer.There is a consensus on neoadjuvant therapy for patients who with borderline resectable and locally advanced, but for the patients who with resectable remains controversial.

Abstract
Objective: Type 2 diabetes mellitus (T2DM) is a chronic condition resulting from insulin resistance and insufficient β-cell secretion, leading to improper glycaemic regulation. Previous studies have found that excessive fat deposits in organs such as the liver and muscle can cause insulin resistance through lipotoxicity that affects β-cell function. The relationships between fat deposits in pancreatic tissue, the function of β-cells, the method of visceral fat evaluation and T2DM have been sought by researchers. This study aims to elucidate the role of pancreatic fat deposits in the development of T2DM using quantitative computed tomography (QCT), especially their effects on islet β-cell function. Methods: We examined 106 subjects at the onset of T2DM who had undergone abdominal QCT. Estimated pancreatic fat and liver fat were quantified using QCT and calculated. We analysed the correlations with Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) scores and other oral glucose tolerance test-derived parameters that reflect islet function. Furthermore, correlations of estimated pancreatic fat and liver fat with the area under the curve for insulin (AUCINS) and HOMA-IR were assessed with partial correlation analysis and demonstrated by scatter plots. Results: Associations were found between estimated liver fat and HOMA-IR, AUCINS, the modified β-cell function index (MBCI) and Homeostatic Model Assessment β (HOMA-β). However, no significant differences existed between estimated pancreas fat and those parameters. Similarly, after adjustment for sex, age and body mass index, only estimated liver fat was correlated with HOMA-IR and AUCINS. Conclusions: This study suggests no significant correlation between pancreatic fat deposition and β-cell dysfunction in the early stages of T2DM using QCT as a screening tool. The deposits of fat in the pancreas and the resulting lipotoxicity may play an important role in the late stage of islet cell function dysfunction as the course of T2DM progresses.

Abstract
Deformation twinning plays a vital role in accommodating plastic deformation of hexagonal-close-packed (hcp) metals, but its mechanisms are still unsettled under high strain rate shock compression. Here we investigate deformation twinning in shock-compressed Mg as a typical hcp metal with in situ, ultrafast synchrotron x-ray diffraction. Extension twinning occurs upon shock compression along ⟨112[over ¯]0⟩ and ⟨101[over ¯]0⟩, but only upon release for loading along ⟨0001⟩. Such deformation mechanisms are a result of the polarity of deformation twinning, which depends on directionality and relative magnitude of resolved shear stress and may be common for Mg and its alloys in a wide range of strain rates.

Abstract
Objective: To explore the magnetic resonance imaging (MRI) imaging technique and the clinical application in ligament and tendons of elbow. Methods: The study was reviewed and approved by an institutional review board of Beijing Jishuitan Hospital. A total of 20 normal volunteers with 40 elbows including 12 males and 8 females, aged from 20 to 55 years, with an average age of 35 years and 38 patients with 38 elbows who complained elbow pain with elbow injuries including 23 males and 15 females, ranged in age from 9 to 77 years, with an average age of 41 years old were chosen to undergo magnetic resonance examination between May 2013 and October 2018.All subjects underwent examination on coronal T(1)WI scan and PD-FS on three planes respectively in a prone position. Then the MRI characteristics of tendons in elbow of healthy volunteers and patients with elbow injuries were studied and the MRI features of tendon injury were compared with the surgical results and confirmed by double-blind method. Results: Twenty normal volunteers without tendons or ligament injures showed homogeneous low-signal-intensity on T(1)-weighted and proton fat saturation sequence (PD-FS) images.In the 38 patients with elbow injuries, there were 44 tendon injuries, including 14 cases of common extensor tendon injuries, 10 cases of common flexor tendon injuries, 3 cases of biceps tendon injuries, 7 cases of brachialis tendon injuries and 10 cases of triceps tendon injuries. The injuried tendons became thicker and discontinuity in T(1)WI and demonstrated heterogeneously increased signal intensity with effusion of tendon sheath in PD-FS. Partial tear showed discontinuity and thickening of tendons and the complete tear showed that the tendons were interrupted, retracted, the fiber structure disappeared and was filled with liquid, and the surrounding soft tissue edema was found. Conclusions: MRI can demonstrate the anatomy and injuries features of tendons in elbow joint accurately. It is significance for the early diagnosis and treatment protocols of the tendons injuries.
