Abstract
BACKGROUND Lateral malleolus fractures are very common, and the distal fibular geometry is complex. This study aimed to classify the lateral malleolus fossa (MF) into different types by characterizing the lateral MF imaging morphology and exploring the relationship between the lateral MF and internal fixation position after distal fibula fractures. METHODS Anteroposterior CT reconstruction was performed on 248 subjects. After reconstruction, the deepest point of the lateral MF was located, and then, the cross-sectional shape of the lateral MF was observed and classified. RESULTS According to the morphology of the CT cross section, the lateral MF was divided into three types: type C (43.1%), type V (32.2%), and type Flat (24.7%). Type V (3.98 ± 0.82) was significantly longer than type C(2.83 ± 0.54) and type Flat (1.84 ± 0.42) in cd. Similarly, in ∠α, Type Flat(136.31 ± 9.63) was the largest, followed by type C (116.51 ± 8.79), and type V (89.31 ± 9.07) was the smallest. Other measurements were not found any significant differences between the above. CONCLUSION According to the morphology of the CT cross section, the lateral MF was divided into three types: type C, type V and type Flat. Type V is most likely to be invaded when fixing the distal fibula. Screws less than 9 mm should be selected when fixing, and screws no more than 10 mm should be selected when there are type C and type Flat of MF.

Abstract
Objective: To investigate the independent and joint effects of chronotype and sleep duration on self-rated health in medical students. Methods: A cross-sectional study was conducted in 1 526 medical students selected through proportional stratified cluster random sampling from a medical university in Zhejiang province. A questionnaire survey was conducted to collect the information about their basic demographic characteristics, chronotype, sleep duration, and other lifestyle factors such as midnight snack, sedentary behavior, physical activity, meal time, and self-rated health. The independent and joint effects of chronotype and sleep duration on self-rated health were assessed by logistic regression model after controlling for confounding variables. Results: The numbers of the students with evening chronotype, neutral chronotype, and morning chronotype were 664 (43.5%), 442 (29.0%), and 420 (27.5%), respectively. Among the medical students, 42.8% (653) had poor self-rated health. Compared with those with the morning chronotype, the adjusted ORs for those with neutral chronotype and evening chronotype were 1.69 (95%CI: 1.23-2.31) and 2.43 (95%CI: 1.81-3.26), respectively, trend test P<0.001. Compared with those with sleep duration of 8 h or above per night, the adjusted ORs for those with sleep duration of 7 and ≤6 h per night were 1.40 (95%CI: 1.07-1.84) and 2.38 (95%CI: 1.69-3.37), respectively, trend test P<0.001. In the joint effect, compared with those with the morning chronotype and sleep duration of 8 h or above per night, the adjusted OR for those with evening chronotype and sleep duration of ≤6 h per night was 6.53 (95%CI: 3.53-12.09). Conclusions: Both evening chronotype and insufficient sleep were associated with increased odds of poor self-rated health in medical students, and they had joint effects. Therefore, it is necessary to promote early to bed, early to rise and adequate sleep in medical student to maintain their health.

Abstract
Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

Abstract
Objectives: To investigate the clinicopathological and prognostic significance of International Endocervical Adenocarcinoma Criteria and Classification (IECC) in classifying endocervical adenocarcinomas among Chinese women. Methods: A total of 286 endocervical adenocarcinomas diagnosed from January 2013 to December 2019 at the Women's Hospital, Zhejiang University School of Medicine were identified and included. The cases were reviewed and reclassified based on IECC. The histological types were correlated with p16 immunostaining, human papilloma virus (HPV) mRNA status, the clinicopathological parameters including the International Federation of Gynecologic Oncology (FIGO) stage, and clinical follow-up data. Results: The patients aged from 19 to 77 (median 47) years. There were 223 patients at FIGO stage Ⅰ, 22 at stage Ⅱ, 38 at stage Ⅲ and 3 at stage Ⅳ. The IECC types included 213 (74.5%) HPV-related adenocarcinomas (HPVA), 60 (21%) non-HPV-related adenocarcinomas (NHPVA), and 13 (4.5%) adenocarcinomas, no other specified (NOS). The major histological subtypes in HPVA and NHPVA were common type (n=156, 54.5%) and gastric type (GAC, n=46, 15.9%), respectively. The p16 positive rates in HPVA, NHPVA and adenocarcinoma, NOS were 92% (173/188), 26.6% (17/64) and 61.5% (8/13), respectively, and those of HPV mRNA hybridization in situ were 89.4% (144/161), 0/18 and 7/13, respectively. Compared to HPVA, NHPVA was more frequently associated with older age, FIGO stage Ⅱ-Ⅳ, neural involvement, lymphovascular invasion and aberrant p53 expression (P<0.05). Univariate survival analysis showed that age (>47 years), NHPVA, GAC, FIGO stage Ⅱ-Ⅳ, neural involvement, lymphovascular invasion and aberrant p53 expression were indicators for a poorer overall survival and tumor recurrence (P<0.05). Mucinous HPVA showed worse clinical outcomes compared to usual-type HPVA (P<0.01). Multivariate survival analysis demonstrated that FIGO stage Ⅱ-Ⅳ, NHPVA and aberrant p53 expression were independent indicators for poor overall survival while FIGO stage Ⅱ-Ⅳ and GAC were independently associated with tumor recurrence (P<0.05). Conclusions: The two broad IECC categories, HPVA and NHPVA, not only provide morphological links to the etiology (HPV infection), but also have significant clinicopathological and prognostic relevance.

Abstract
This study aimed to evaluate the anti-tumor effect of a new generation of protease inhibitor, oprozomib (OPZ), used alone and in combination with cisplatin, also called CDDP, on cervical cancer. Five different types of cervical cancer cell lines - HeLa, Caski, HeLa-CDDP, C33a, and SiHa - and one nontransformed cervical cell line - HaCaT -were treated with OPZ alone or in combination with cisplatin. The inhibitory effects of OPZ and cisplatin on the proliferation of cervical cancer cells were then analyzed using cytotoxicity tests, flow cytometry, and Western blotting. It was found that OPZ alone or in combination with cisplatin can reduce the proliferation of the five types of cancer cells by enhancing the lysis of caspase-3 and PARP and inducing cancer cell apoptosis. In the combined treatment, OPZ was found to inhibit the degradation of inhibitory factor κB alpha induced by cisplatin, thereby inhibiting the activation of NF-κB, which causes cisplatin resistance, and enhancing the sensitivity of the tumor cells to cisplatin. Moreover, OPZ promoted the phosphorylation of the apoptosis signaling pathway JNK that was activated by cisplatin, thereby inducing tumor cell apoptosis. These findings provide a theoretical basis for the clinical use of OPZ alone and in combination with cisplatin in the treatment of cervical cancer.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by coughing, the production of excess sputum, and dyspnea. Patients with excessively thick sputum may have frequent attacks or develop more serious disease. The guidelines recommend airway clearance for patients with excessive sputum who are hospitalized with COPD. The active cycle of breathing technique is the most common non-pharmacological airway clearance technique used by physiotherapists. However, the effectiveness of the technique is not always guaranteed. Active cycle of breathing techniques require the initial dilution of the sputum, usually by inhalation drugs, which may have limited effects. Recent studies have found that phonophoresis decreases inflammation, suggesting the potential of the combined usage of active cycle of breathing techniques and phonophoresis. Therefore, the aim of this study is to explore the effectiveness and safety of combining active cycle of breathing technique and phonophoresis in treating COPD patients. Methods and analysis We propose a single-blind randomized controlled trial using 75 hospitalized patients diagnosed with COPD with excessive sputum production. The patients will be divided into three groups. The intervention group will receive active cycle of breathing techniques combined with phonophoresis. The two comparison groups will be treated with active cycle of breathing techniques and phonophoresis, respectively. The program will be implemented daily for 1 week. The primary outcomes will be changes in sputum viscosity and production, lung function, and pulse oximetry. Secondary outcomes include the assessment of COPD and anxiety, measured by the COPD Assessment Test scale and the Anxiety Inventory for Respiratory Disease, respectively; self-satisfaction; the degree of cooperation; and the length of hospital stay. All outcome measures, with the exception of sputum production and additional secondary outcomes, will be assessed at the commencement of the study and after 1 week’s intervention. Analysis of variance will be used to investigate differences between the groups, and a p-value of less than 0.05 (two-tailed) will be considered statistically significant. Discussion This study introduces a combination of active cycle of breathing techniques and phonophoresis to explore the impact of these interventions on patients hospitalized with COPD. If this combined intervention is shown to be effective, it may prove to be a better treatment for patients with COPD. Trial registration The trial was registered prospectively on the Chinese Clinical Trial Registry on 24 December 2019.ClinicalTrials.gov ChiCTR1900028506. Registered on December 2019.

Abstract
BACKGROUND While active cycle of breathing technique for chronic obstructive pulmonary disease patients with more sputum can improve clinic outcomes, less is known about sputum viscosity and sputum production of the intervention. OBJECTIVE The purpose of our study was to explore the effect of active cycle of breathing technique on sputum viscosity and production among patients with chronic obstructive pulmonary disease. DESIGN This was a two-arms, parallel, randomized clinical trial. SETTING Study enrollment, randomization and implementation were conducted in the department of respiratory medicine inpatient at the Medical Center in Changchun, China. PARTICIPANTS Hospitalized patients due to chronic obstructive pulmonary disease who met additional eligibility criteria were randomized to active cycle of breathing technique (n = 50) or usual care group (n = 50). METHODS Patients in the intervention group received a week-long intervention from an experienced physical therapist. Patients in the usual care group received usual care as well as information and advice in the light of their health plan from respiratory medicine. The primary outcome was the changes on sputum viscosity and production. RESULTS Among one hundred patients who were randomized (mean [SD] age, 54.89 [12.06] years; females, 58%), ninety-six participants completed the study. No significant differences were found between two groups on the changes of sputum viscosity (t = 0.277, P = 0.782). And there were insignificant differences between groups in the average amount of sputum among 1 h (Z=-1.848, P = 0.065) and significant differences in the average amount of sputum among 24 h (Z=-2.236, P = 0.025). From admission to one week recovery, the changes in ratio of forced expiratory volume in 1 s to forced vital capacity (Z=-4.511, P<0.0001) and arterial oxygen saturation (Z=-2.997, P = 0.003) were better in active cycle breathing technique group. Total Chronic Obstructive Pulmonary Disease Assessment Test scale were similar among two groups (Z=-1.818, P = 0.069). No adverse events occurred during the study. CONCLUSION For patients with chronic obstructive pulmonary disease, active cycle of breathing technique can significantly result in sputum production and respiratory function, especially those of Global Initiative for Chronic Obstructive Lung Disease classification level 3, but did not result in the short-term improvement of sputum viscosity, quality of life and cost effectiveness.

Abstract
Objective: To establish an artificial intelligence (AI)-assisted diagnostic system for lung cancer via deep transfer learning. Methods: The researchers collected 519 lung pathologic slides from 2016 to 2019, covering various lung tissues, including normal tissues, adenocarcinoma, squamous cell carcinoma and small cell carcinoma, from the Beijing Chest Hospital, the Capital Medical University. The slides were digitized by scanner, and 316 slides were used as training set and 203 as the internal test set. The researchers labeled all the training slides by pathologists and establish a semantic segmentation model based on DeepLab v3 with ResNet-50 to detect lung cancers at the pixel level. To perform transfer learning, the researchers utilized the gastric cancer detection model to initialize the deep neural network parameters. The lung cancer detection convolutional neural network was further trained by fine-tuning of the labeled data. The deep learning model was tested by 203 slides in the internal test set and 1 081 slides obtained from TCIA database, named as the external test set. Results: The model trained with transfer learning showed substantial accuracy advantage against the one trained from scratch for the internal test set [area under curve (AUC) 0.988 vs. 0.971, Kappa 0.852 vs. 0.832]. For the external test set, the transferred model achieved an AUC of 0.968 and Kappa of 0.828, indicating superior generalization ability. By studying the predictions made by the model, the researchers obtained deeper understandings of the deep learning model. Conclusions: The lung cancer histopathological diagnostic system achieves higher accuracy and superior generalization ability. With the development of histopathological AI, the transfer learning can effectively train diagnosis models and shorten the learning period, and improve the model performance.

Abstract
Objective: To analyze the effectiveness and immunogenicity of enterovirus-A71(EV-A71) vaccine in immunization program. Methods: A cohort study was conducted in immunization clinics in Jing'an district in Shanghai from October to December 2017. Children who received EV-A71 vaccine based on a 2-dose schedule (on day 0 and day 30) were enrolled as vaccine group and those who received no EV-A71 vaccine were enrolled as control group. After 1-year follow-up, the effectiveness and neutralizing antibody level and the positive results of antibody immunogenicity in vaccine group were analyzed. Results: A total of 3 018 children aged 8-20 months were enrolled, in whom 1 211 were in vaccine group and 1 807 were in control group. The vaccine effectiveness was 100% against EV-A71-associated hand, foot, and mouth disease (HFMD) indicated by 1 year follow-up (95%CI: -66.99%-100.00%). The geometric mean titer of neutralizing antibody (GMT) was 41.76 (95%CI: 35.60-49.34) at day 60 and 28.44(95%CI: 23.59-34.54) at day 365 in 124 children in vaccine group. Conclusions: In children, EV-A71 vaccine elicited EV-A71-specific immune response. Less EV-A71-associated HFMD cases have been observed, further observation is needed.

Abstract
Objective: To analyze the clinicopathological features of clear cell tumor of the lung (CCTL). Methods: A total of 9 cases were collected from August 2008 to August 2019 in the Department of Pathology of the First Medical Center of PLA General Hospital and Hainan Hospital of PLA General Hospital. Their clinical data, pathological characteristics, immunohistochemical staining and special staining results were summarized and analyzed. Results: There were 3 males and 6 females, aged from 28 to 70 years (average 52.2 years). All tumors were located in the peripheral part of the lung, and were solitary in 8 cases, and multiple (24 nodules) in 1 case. The lesion was round or oval, with clear boundary. The diameter of the nodule was 0.5-5.5 cm. Histologically, the tumor cells were oval, short fusiform or polygonal, with obvious nucleoli. The tumor cells were mostly distributed in sheet around thin-walled vessels, and there was hyaline degeneration around the blood vessels. Neither necrosis nor mitosis could be seen. Immunohistochemical staining showed tumor cells were diffusely positive for Vimentin, and CD34, Melan-A, specific monoclonal antibody against melanoma (HMB45) and S-100 were positive with different degrees. Broad spectrum cytokeratin (CK), epithelial membrane antigen (EMA), smooth muscle actin (SMA), desmin, CD10, paired box gene 8 (PAX-8) or myomodulatory protein (Myo-D1) were all negative. The positive index of the proliferating cell nuclear antigen (Ki-67) was low. Schiff dyeing with periodate (PAS) staining was positive, PAS staining of glycogen digested by amylase (d-PAS) staining was negative. All the tumors in the nine cases were resected and patients were followed up for 5-137 months. Except 1 case was lost for follow-up, the other 8 cases survived without recurrence or metastasis of the disease. Conclusions: CCTL is a rare benign tumor, most of which are single, few of which can be multiple; histopathological characteristics and immunohistochemical staining are helpful for diagnosis and differentiated diagnosis. After complete resection, the prognosis was good. However, when histological features indicating malignancy, intense follow-up should be considered.

Abstract
Objective: To understand the provision of preventive medicine curriculum system in the training programs of clinical medicine in the era of Healthy China. Methods: A total of 36 training programs of clinical medicine were selected from different areas of China for a statistical analysis on their basic information, involvement of concept of preventive medicine in program objectives, and provision of preventive medicine curriculum system. Results: Of all the 36 training programs of clinical medicine, 22(61%) have no mentions of prevention medicine in their program objectives; only one university's training program states preventive medicine together with basic medicine and clinical medicine as one of the three main disciplines. The total class hours for the core courses of preventive medicine (hygiene, medical statistics, epidemiology, evidence-based medicine, and social medicine) range from 80 to 252, with an average of (156.7±43.2) hours. The average percentage of class hours for preventive medicine courses among the total class hours is 4.3%±1.1% (range: 2.5%-7.5%), and obvious differences exist among universities. Conclusions: In current training programs of clinical medicine, the proportion of prevention medicine curriculum is insufficient, the percentage of hours for preventive medicine course is very low, and the differences among various universities are obvious. It is urgently needed to strengthen preventive medicine curriculum in training programs for clinical medical students in new era. It is suggested to further promote the concept of putting prevention first, improve the curriculum system of clinical medicine, intensify the integrated development preventive medicine and clinical medicine and pay attention to clinical research ability enhancement for the further improvement of training program of clinical medicine.

Abstract
Objective: To evaluate the long-term outcome of patients with hypertrophic obstructive cardiomyopathy(HOCM) after percutaneous transluminal septal ablation(PTSMA). Methods: HOCM patients who underwent PTSMA and surgical myectomy at the Chest Hospital of Shanghai Jiao Tong University from April 2001 to February 2019 were included in this retrospective analysis. Patients were divided into PTSMA group and surgical myectomy group. In addition, patients undergoing PTSMA were further divided into HOCM-PTSMA non-survivor group and HOCM-PTSMA survivor group. The general clinical information, procedural/surgical information and complications during hospitalization were compared between groups. Multivariate Cox regression model was used to analyze the independent risk factors for all-cause death in HOCM patients after PTSMA. Results: A total of 104 patients with HOCM who underwent PTSMA were enrolled. Mean age of the patients was (54±15) years old, including 41 females (38.7%). The follow-up time was 37.5(14.3, 76.8) months. At the last follow-up, 12 patients died (HOCM-PTSMA non-survivor group) and 92 were alive(HOCM-PTSMA survivor group). The proportion of patients with NYHA function class Ⅲ/Ⅳ was higher(P=0.036), and the posterior wall of the left ventricle was thicker(P=0.006) in the HOCM-PTSMA non-survivor group than in the HOCM-PTSMA survivor group. The immediate success rate of PTSMA in this cohort was 66%(70/104). The amount of absolute alcohol during the operation in the HOCM-PTSMA non-survivor group was (2.9±0.8) ml, which tended to be higher as compared to that in the HOCM-PTSMA survivor group((2.4±1.0)ml, P=0.056). Kaplan-Meier survival curve analysis showed that patients with HOCM who underwent PTSMA had an all-cause mortality-free survival rate of 90.1%, 78.3%, and 56.9% at 5, 10 and 15 years, and a HOCM-free survival rate of 91.3%, 79.4% and 57.7% at 5, 10 and 15 years, respectively. Multivariate Cox regression analysis showed that age≥ 65 years was an independent risk factor for all-cause death after PTSMA in patients with HOCM (HR=2.697, 95%CI 1.292-18.977, P=0.020). There were 32 patients in the surgical myectomy group. The proportion of patients with NYHA function class Ⅲ/Ⅳ was higher than that in the PTSMA group(P<0.001), while age, gender, and major comorbidities(atrial fibrillation, coronary heart disease, hypertension, and diabetes) as well as the left atrium dimension were all similar between the two groups(all P>0.05). Patients in the surgical myectomy group were followed up for 38.0(17.6, 64.2)months, and no deaths occurred during the follow-up period. Kaplan-Meier survival curve analysis showed that there were no statistically significant differences in all-cause-free and HOCM-free survival rates between patients in PTSMA group and surgical myectomy group(P=0.089 and 0.110, respectively). Conclusion: PTSMA is safe and effective for the treatment of patients with HOCM, and the long-term survival rate of patients after PTSMA is similar as patients undergoing classical surgical myectomy surgery.

Abstract
Objective: To explore the mediation mechanism of coronary artery lesion among both male and female Kawasaki disease (KD) children. Methods: Children with KD that hospitalized in the Wenzhou Medical University affiliated Yuying Children's Hospital from January 2009 to December 2014, were included in this study. Differences on demographical characteristics, clinical manifestations, laboratory indicators, regimen and time of treatment, results from pre/post echocardiography and treatment between male and female patients, were compared. The independent effect of gender on the risk of coronary artery lesions (CAL) was evaluated, and the mediating effect of BMI, visiting time and KD type on the association between gender and CAL were also studied. Results: The average BMI level of male patients was higher than that of female patients. The difference was statistically significant (P<0.001). The prevalence of overweight among male patients (20.9%) was higher than female (14.1%). The difference was statistically significant (P=0.011). Data from the multivariate logistic regression analysis confirmed that the incidence of CAL in male patients was higher than that in female patients (aOR=1.50, 95%CI: 1.06-2.12) but the CAL was mainly different before on the immunoglobulin therapy. Results from the mediation analysis showed that BMI was an important mediator in the association between gender and CAL, with the indirect effect as 1.05 (95%CI: 1.01- 1.10) and the proportion mediated as 13.0%. Conclusions: Male patients presented higher incidence of CAL but was mainly reflected in the difference of CAL before the treatment. BMI was probably an important mediator related to the association between gender and CAL.

Abstract
Objective: To investigate the predictive value of epicardial adipose tissue volume (EATV) and inflammatory factors on in-stent restenosis (ISR) after percutaneous coronary implantation (PCI) in patients with coronary heart disease (CAD). Methods: A total of 407 patients with CAD who were treated with drug-eluting stents in TEDA international cardiovascular disease hospital were enrolled from November 2016 to October 2017. Levels of inflammatory cytokines such as high sensitive c-reactive protein (Hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor (TNF-α) were detected. EATV was measured preoperatively by multi-sliced CT. Patients were divided into ISR group (n=52) and N-ISR group (n=355) according to ISR occurred within 1 year after procedure. The relationship between EATV and inflammatory factors and ISR after PCI was analyzed. Results: The differences between ISR group (n=52) and N-ISR group (n=355) were statistically significant in terms of diabetes history, IL-6, TNF-α, EATV ((150±36) cm(3)vs(120±40) cm(3),P=0.001)), bifurcation lesions, stent length and Gensini score (P<0.05). Multivariate Logistic regression analysis results showed that diabetes history,bifurcation lesions, TNF-α, EATV, and Gensini score were risk factors for in-stent restenosis.The area under the ROC curve (AUC) of EATV, TNF-α, and IL-6 in patients with CAD after PCI was 0.712, 0.752 and 0.675 (95%CI 0.648-0.776, 0.686-0.819, 0.584-0.766, respectively, all P<0.001), with a sensitivity of 86.5%, 67.3% and 69.2%, a specificity of 53.8%, 74.4% and 70.1% and a cut-off value of 116.61 cm(3),138.40 µg/L and 126.4 µg/L, respectively. Conclusion: EATV, TNF-α, and IL-6 have certain predictive values for in-stent restenosis, and can be used as clinical indicators to predict in-stent restenosis.

Abstract
Objective: To explore the difference of liver inflammation and fibrosis in patients with chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV) infection, and to investigate the relationship between hepatic pathology and alanine aminotransferase (ALT). Methods: 57 patients with chronic HCV infection and 346 patients with chronic HBV infection who were hospitalized at Shengjing Hospital of China Medical University from January 2012 to September 2016 were enrolled. In chronic HBV infection, including 88 cases whose ALT were more than two times of upper limited of normal (ALT≥2×ULN) and 258 cases whose ALT were less than two times of upper limited of normal (ALT < 2×ULN).All the patients were underwent liver biopsy. Chronic HBV infection (ALT≥2×ULN and ALT < 2×ULN) and chronic HCV infection were compared respectively. Statistical analyses were performed using a Univariate χ²-test and Mann-Whitney U test for comparison. Correlations between variables were analyzed using Spearman's rank correlation. Results: In chronic HBV infection group, 169 cases (48.8%) had inflammation grade≥2 (G≥2), 98 cases (28.3%) had fibrosis stage≥2 (S≥2), 81 cases (23.4%) with G≥2 and S≥2.In the ALT < 2×ULN group, there were 109 cases (42.2%) with G≥2, 62 cases (24%) with S≥2, 49 cases (19%) with G≥2 and S≥2. In the ALT≥2×ULN group, 60 cases (68.2%) with G≥2, 35 cases (39.8%) with S≥2, 31 cases (35.2%) with G≥2 and S≥2. The grade of inflammation and fibrosis have significantly different between ALT≥2×ULN group and ALT < 2×ULN group (χ² = 17.66, χ² = 8.06, P < 0.01). In chronic HCV infection group, 47 cases (82.5%) with G≥2, 20 cases (35.1%) with S≥2, 20 cases (35.1%) with G≥2 and S≥2. ALT had no correlation with inflammation and fibrosis (P > 0.05). The grade of inflammation was significantly different between chronic HCV infection and chronic HBV infection whose ALT < 2×ULN (χ² = 30.19, P < 0.01) but the fibrosis have no difference (χ² = 2.96, P > 0.05). Compared with chronic HBV infection whose ALT≥2×ULN, both inflammation and fibrosis had no significantly different (χ² = 3.65, χ² = 0.32, P > 0.05 respectively). Conclusion: In chronic HBV infection whose ALT < 2×ULN, about 30%-40% liver tissue with significant necroinflammation and /or fibrosis. About 80% chronic HCV infection with significant necroinflammation, and the grade of inflammation has no correlation with ALT. The grade of inflammation has significantly different between chronic HCV infection group and chronic HBV infection group whose ALT < 2×ULN.

Abstract
Objective: To elucidate the clinicopathologic characteristics of atypical epithelioid trophoblastic lesions with cyst and fistula formation after cesarean section. Methods: The clinical and pathological data of 4 cases of post-cesarean atypical epithelioid trophoblastic lesions with cyst and fistula formation diagnosed at Women's Hospital, School of Medicine, Zhejiang University during April 2007 to June 2018 were evaluated by hematoxylin and eosin stain and EnVision two-step immunohistochemical staining technique. Results: The age of the 4 patients ranged from 32 to 41 years, with a mean age of 36.5 years. Three patients recieved cystectomy and one underwent subtotal hysterectomy. Histologically, the lesions were well circumscribed and consisted of uniform cells of medium size, irregularly enlarged with hyperchromatic nuclei and 1 to 2 inconspicuous nucleoli embedded in abundant hyalinized matrix with fibrinoid material in the center. The cells exhibited immunohistochemical feature of chorionic-type intermediate trophoblastic cells (CK18+, p63+ and CD146-). All patients were alive without recurrence during follow-up of 1 to 40 months (mean=22 months). Conclusion: Atypical epithelioid trophoblastic lesion with cyst and fistula formation after cesarean section has unique histological features, and its biological behavior and prognosis are still unclear, which need further exploration.

Abstract
Objective: To further evaluate the clinical value of epicardial adipose tissue volume (EATV) in predicting the prognosis of coronary heart disease (CHD) after percutaneous coronary intervention (PCI). Methods: From July 2013 to July 2016 in TEDA International Cardiovascular Disease Hospital, a total of 474 patients diagnosed with CHD were included in this study.According to the result of EATV, patients were divided into three groups, group A (EATV≤75 ml), group B (75 ml<EATV<150 ml), and group C (EATV≥150 ml). Then the level of body mass index (BMI), hypersensitive c-reactive protein (hs-CRP), interleukin (IL)-6 and tumor necrosis factor (TNF)-α were tested for all the three groups.All the patients were followed up for 1 year for major adverse cardiovascular events (MACE). The clinical value of EATV in predicting the occurrence of MACE events was evaluated. Results: The BMI, level of hs-CRP, TNF-α in group B were higher than group A, group C were significantly higher than group B, with statistically significant difference across all the comparisons (P<0.05). Spearman correlation analysis showed EATV was positively correlated with hs-CRP, IL-6, TNF-α (r=0.675-0.700, P<0.01). The incidence of MACE in the three groups were 8.50% in group C, 5.26% in group B, 3.13% in group A, and the differences were all significant (P<0.01). ROC curve showed the cut-off value of EATV level was 120.39 ml to predict MACE (area under cure: 0.751, 95%CI: 0.634-0.868, P<0.01), and the sensitivity was 72.7%, the specificity was 61%.EATV>120.39 ml can be used as an independent risk factor for predicting the occurrence of MACE. Conclusion: The level of EATV is closely related to the occurrence of MACE events, and EATV>120.39 ml is an independent risk factor for MACE in patients with CHD after PCI.

Abstract
It is known that physiological overproduction of nitric oxide (NO) contributes to oxidative stress and inflammation. Our published studies indicated that vitamin A (VA) reduces NO-induced oxidative stress in bovine mammary epithelial cells (BMECs) by increasing antioxidant enzyme activities. However, the precise mechanism is unclear. The present study was conducted to examine the protective effects of VA on NO-induced damage to BMECs in vitro using diethylenetriamine nitric oxide (DETA-NO) as the NO donor and to explore the intracellular signaling mechanisms of VA that involve nuclear factor erythroid 2-related factor (Nrf2) and nuclear factor kappa-B (NF-κB). Subconfluent BMECs were divided into 10 treatment groups with 6 replicates per treatment and were cultured with dimethyl sulfoxide (DMSO, vehicle negative control) or 0, 0.05, 0.1, 0.2, 0.5, 1, 2, 3, or 4 μg/mL of VA for 24 h and then incubated in the absence or presence of DETA-NO (1,000 μmol/liter) and VA for an additional 6 h. The results showed that exposure to DETA alone decreased cell proliferation compared with the negative control. Pretreatment with VA promoted the proliferation of BMECs, increased the activities of antioxidative enzymes including selenoprotein glutathione peroxidase (GPx) and thioredoxin reductase (TrxR) and their gene and protein expression but decreased NO and interleukin 1 (IL-1) contents in a quadratic manner (P < 0.05). In addition, the expression of mRNA and protein of factors that are related to NF-κB or Nrf2 signaling pathways in BMECs were regulated by VA in a quadratic dose-dependent manner; VA at a concentration of 1 μg/mL exhibited the strongest effect. Together, these results suggest that VA promotes antioxidant functions of BMECs by regulating the synthesis of selenoproteins including GPx and TrxR and by reducing concentrations of IL-1 and NO in vitro by modulating Nrf2 and NF-κB signaling pathways.

Abstract
Objective: To investigate clinicopathologic features and prognosis of adenoid cystic carcinoma (ACC) involving external auditory meatus. Methods: The clinical presentation and follow-up data of 63 patients with ACC of external auditory canal were collected from January 2006 to February 2017 at PLA General Hospital and Hainan Branch of PLA General Hospital. The clinicopathologic features and prognostic factors of external auditory canal ACC were analyzed. Results: (1) There were 28 males and 35 females and the average age of the first diagnosis was 48.9 years (22-81 years). The tumors showed cribriform pattern in 35 cases (15 cases of late stage), tubular pattern in 14 cases (8 cases of late stage), and solid pattern in 14 cases (9 cases of late stage). Cases with solid pattern was relatively more frequent than that of cribriform pattern and tubular pattern, but the difference was not statistically significant (P>0.05). (2) The average follow-up time was 62.4 months (2-228 months) in the 57 available cases. Among the 33 cases with recurrence, 18 cases had local recurrence and 15 cases had distant metastasis. The mean recurrence time was 40.6 months (2-204 months). Nine patients died of ACC: 2 cases in early stage (died at 48 and 102 months after the first treatment), 7 cases in late stage and 57 with (died at 9, 30, 32, 60, 72, 94 and 228 months). (3) Among the 37 patients with perineural invasion, there were 21 cases of cribriform pattern, 4 cases of tubular pattern and 12 cases of solid pattern; the number of cases in early stage and late stage were 15 and 22, respectively; and the differences were statistically significant (P<0.05). In addition, 31 cases had otalgia among the 37 patients with perineural invasion, where differences were not significant (P>0.05). (4) Thirty of 45 cases with tumor resection or partial resection of temporal bone had recurrence, whereas 3 of 12 cases of tumor combined with superficial lobectomy of parotid gland had recurrence. The difference was statistically significant (P<0.05). Postoperative adjuvant radiotherapy was given in 19 cases, including 7 cases of early stage (2 cases of recurrence), and 12 cases of late stage (8 cases of recurrence), among which there was no significant difference (P>0.05). Conclusions: ACC occurring in external auditory canal frequently recurs. Superficial parotid lobectomy at the first operation is necessary to prevent tumor recurrence. Postoperative adjuvant radiotherapy has certain curative effect on patients with early stage tumor, but it does not affect the recurrence rate. Patients at late stage are more prone to perineural invasion than those in early stage. In addition, cribriform and solid patterns are more common that tubular pattern, and there is no significant correlation between perineural invasion and otalgia.

Abstract
Objective: To investigate the effects ofepicardial adipose tissue volume (EATV) and inflammatory factors on left ventricular diastolic function in patients with coronary heart disease(CHD). Methods: The clinical data of patients with coronary heart disease receiving coronary artery intervention therapy from January 2014 to October 2015 in TEDA international cardiovascular hospital were preoperatively collected.We measured the indexes of EATV and left ventricular diastolic function. Results: The difference of age (F=7.76, P=0.01), IL-6 (F=14.34, P<0.01), Hs-CRP (F=4.08, P=0.04), adiponect-in (F=4.50, P=0.04) and EATV (F=71.29, P<0.01) between the diastolicdysfunction group (n=156) and the normal group (n=76) was statistically significant.Multivariate logistic regression analysis showed that EATV was a risk factor for left ventricular diastolic dysfunction in patients with coronary artery disease (P<0.05), OR=1.05, 95%CI (1.03-1.06). The AUC value of EATV in the diagnosis of left ventriculardiastolic function in patients with coronary heart disease was 0.79, 95%CI (0.73-0.85) P<0.01. Conclusions: EATV can be used as an independent risk factor for left ventricular diastolic dysfunction.It has some non-invasive diagnosis and predictive value, and it can be used as a new therapeutic target.

Abstract
The histochemical distribution of acid phosphatase (ACP), alkaline phosphatase (ALP), non-specific esterase (NSE), peroxidase (POD) and mucous-cell types was evaluated in the gastrointestinal tract of the half-smooth tongue sole Cynoglossus semilaevis. The enzymes were detected in the entire stretch of the gastrointestinal tract. ACP activity was found in the supranuclear region of enterocytes and the lamina propria of the intestine, as well as the cytoplasm of epithelial cells of the stomach. The staining intensity of ACP in the anterior and posterior intestines was stronger than in the stomach. ALP activity was detected in the striated border of enterocytes and muscularis of the whole intestine, lamina propria and supranuclear cytoplasm of the enterocytes in the anterior intestine, as well as in the blood vessels of the stomach. The staining intensity for ALP in the anterior intestine was stronger than in the posterior segment and the latter was stronger than in the stomach. NSE activity was detected in the cytoplasm of the epithelial cells in the entire gastrointestinal tract, with the anterior intestine showing stronger intensity than the stomach. POD activity was located in the blood cells of the lamina propria of the gastrointestinal tract and the levels in the stomach were similar to the anterior and posterior intestines. Alcian blue (pH 2·5) periodic acid Schiff (AB-PAS) histochemical results revealed three types of mucous cells in the gastrointestinal tract. Type I cells (PAS+AB-) were observed among the gastric mucosa columnar cells in the stomach and enterocytes in the basal region of the villi and in the middle and top regions of the intestinal villi. Type II cells (PAS-AB+) and type III cells (PAS+AB+) were not detected in the stomach but were distributed ubiquitously among enterocytes in the middle and top regions of the intestinal villi.

Abstract
Objective: To study the clinicopathologic features of thyroid-like follicular renal cell carcinoma. Methods: Clinical data were collected in 5 cases of thyroid-like follicular renal cell carcinoma. HE staining and immunohistochemistry were carried out in surgically-removed specimen to analyze the clinical and pathological features with review of the literatures. Results: The patients aged 20-55 years, with one male and four females; the tumor occurred in the left kidney in three cases and right kidney in two cases. One case had a history of thyroid papillary carcinoma 3 years ago, and the patient had left flank pain, macroscopic haematuria for 2 weeks. The rest four cases had no consciousness of clinical symptoms and signs, without history of thyroid gland surgery; the physical examination found a mass in the kidney and normal thyroid glands. Three patients underwent radical nephrectomy, and the other two patients underwent tumor partial nephrectomy. The tumors were 2-4 cm in size. They showed a solitary nodular mass of well circumscribed with taupe and gray on cut surface. Microscopically, most of tumor cells arranged in thyroid follicular pattern in different sizes, with papillary configuration in a small portion, in four cases; the follicular structure was intermixed with the papillary each half in one case. A large amount of thyroid colloid was deposited within follicule-like structure or papillary axis, lined by simple columnar cells or cubic cells, with obvious atypia, ground-glass nuclei, nuclear groove and rare mitosis. Immunohistochemical staining showed tumor cells were positive for PAX8, and negative for thyroid transcription factor 1 (TTF1) and thyroglobulin (Tg). One of five patients presented with lymph node metastases (4/4) of renal hilum the same time in the diagnosis. Five cases were followed up for 5-84 months after operation, and no tumor progression was found. Conclusions: Thyroid-like follicular renal cell carcinoma is primary renal epithelial malignant tumor. The diagnosis mainly depends on its characteristics of histological appearance, namely similar to the histological morphology of well-differentiated thyroid follicular carcinoma and papillary carcinoma, and the metastasis from the thyroid papillary or follicular carcinoma must be excluded. On the premise of clinical history, immunohistochemical markers TTF1 and Tg have certain value in the differential diagnosis.

Abstract
Bipolar disorder (BD) is a common psychiatric mood disorder affecting more than 1-2%
of the general population of different European countries. Unfortunately, there is no
objective laboratory-based test to aid BD diagnosis or monitor its progression, and
little is known about the molecular basis of BD. Here, we performed a comparative
proteomic study to identify differentially expressed plasma proteins in various BD
mood states (depressed BD, manic BD, and euthymic BD) relative to healthy controls. A
total of 10 euthymic BD, 20 depressed BD, 15 manic BD, and 20 demographically matched
healthy control subjects were recruited. Seven high-abundance proteins were
immunodepleted in plasma samples from the 4 experimental groups, which were then
subjected to proteome-wide expression profiling by two-dimensional electrophoresis
and matrix-assisted laser desorption/ionization-time-of-flight/time-of-flight tandem
mass spectrometry. Proteomic results were validated by immunoblotting and
bioinformatically analyzed using MetaCore. From a total of 32 proteins identified
with 1.5-fold changes in expression compared with healthy controls, 16 proteins were
perturbed in BD independent of mood state, while 16 proteins were specifically
associated with particular BD mood states. Two mood-independent differential
proteins, apolipoprotein (Apo) A1 and Apo L1, suggest that BD pathophysiology may be
associated with early perturbations in lipid metabolism. Moreover, down-regulation of
one mood-dependent protein, carbonic anhydrase 1 (CA-1), suggests it may be involved
in the pathophysiology of depressive episodes in BD. Thus, BD pathophysiology may be
associated with early perturbations in lipid metabolism that are independent of mood
state, while CA-1 may be involved in the pathophysiology of depressive episodes.

PATIENTS AND METHODS This prospective study analyzed 172 patients at two tertiary academic hospitals. All patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its supplementary breast cancer measure (QLQ-BR23) at baseline and at 1 and 2 years postoperatively. The 95% confidence intervals for differences in responsiveness estimates were derived by bootstrap estimation. Scores derived by these instruments were interpreted by generalized estimating equation (GEE) before and after surgery. RESULTS A 2-year follow-up survey of the examined population revealed significant (P < 0.05) improvement in each QOL subscale. In both postoperative surveys, effect size was largest in the QLQ subscales for patients who had received mastectomy with reconstruction and lowest in those who had received modified radical mastectomy. After adjusting for time effects and baseline predictors, GEE approaches revealed the following explanatory variables for QOL: time, type of surgical procedure, age, chemotherapy, radiotherapy, hormone therapy, and preoperative functional status. CONCLUSIONS When evaluating QOL after breast cancer surgery, several factors other than the surgery itself should be considered. Patients should also be advised that their postoperative QOL might depend not only on the success of their operations, but also on their preoperative functional status.

Abstract
The genome of Transmissible gastroenteritis virus (TGEV) displays genetic diversity especially in gene 3 region. Sequence and comparative analysis of 3a and 3b genes of eight Chinese field strains with reference TGEV strains indicated that these strains shared 87.0-100% and 51.5%-100% identities at the nucleotide level, respectively, and 86.1%-100% and 66.2%-100% identities at the amino acid level, respectively. Moreover, in one of the strains (CH/SDQ/08), a 51 nt deletion in the gene 3 region was found. Phylogenetic analysis showed that the eight Chinese strains were more closely related to TGEV strains H165, H16, Miller M6, Miller M60, TS, and CHV than to other reference strains. In addition, this study indicated the presence of different TGEV strains within the same pig herds in China.

Abstract
To analyze antigenic structure of the spike (S) protein of Porcine epidemic diarrhea virus (PEDV), the gene encoding its major immunodominant region S1 was amplified by PCR. We prepared four truncated S1 proteins spanning the entire S1 domain fused to GST protein. To identify the most important antigenic region of S1, the truncated S1-GST fusion proteins were examined for their ability to react with immune serum against PEDV and to elicit the formation of neutralization antibodies in immunized animals. We found that the region of S1 signed as S1D (aa 636789) was able to react with PEDV antiserum and to elicit formation of neutralization antibodies in mice. Moreover, the immune serum against S1D showed the binding ability to the native S protein of PEDV.

Abstract
Porcine teschovirus 1 (PTV-1) (Swine/CH/IMH/03) was isolated from piglets in a farm in Inner Mongolia Province, P.R. China. It was confirmed by electron microscopy, RT-PCR, and sequencing. Comparison of the sequences of the amino acid and nucleotides and phylogenetic analysis of the polyprotein showed that PTV Swine/CH/IMH/03 strain is PTV-1. The isolated virus has closest relationship with Talfan strain, they shared 98.9% and 99.5% homology of amino acids and nucleotides, respectively, in the ORF of polyprotein. To our knowledge, this is the first report about isolation and identification of a PTV in China.

Abstract
Breast cancer is the most common cancer detected in women, accounting for nearly one out of every three cancers diagnosed in the United States. Most cancer patients do not die from the primary tumor but die due to metastasis. Therefore, the study of metastasis is of most importance both to the clinician and patient. In the past, animal models have been used in breast cancer research and mammary gland biology. Our group has also established several animal models to address the function of a novel tumor suppressor gene maspin in breast tumor progression. Maspin was initially isolated from normal mammary epithelial cells. Its expression was down regulated in breast tumors. To test the protective role of maspin overexpression in mammary tumor progression, we crossed maspin overexpression transgenic mice (WAP-maspin) with a strain of oncogenic WAP-SV40 T antigen mice. The bitransgenic mice had reduced tumor growth rate and metastasis. Maspin overexpression increased the rate of apoptosis of both preneoplastic and carcinomatous mammary epithelial cells. Maspin reduced tumor growth through a combination of reduced angiogenesis and increased apoptosis. In a separate animal experiment, maspin overexpressing mammary tumor cells (TM40D) were implanted into the fat pad of syngeneic mice. TM40D tumor cells were very invasive and metastatic. However, both primary tumor growth and metastasis were significantly blocked in TM40D cells that overexpress maspin as a consequence of plasmid or retrovirus infection. These evidences demonstrate that maspin function to inhibit primary tumor growth as well as invasion and metastasis. Elucidating the molecular mechanism of maspin action will shed light on our understanding of breast cancer invasion and metastasis.

Abstract
Maspin is a unique serine protease inhibitor of which the down-regulation is associated with the development of breast cancers. In vitro, recombinant maspin inhibits tumor cell migration and invasion. Overexpression of maspin in transgenic mice is protective against tumor progression. Additionally, maspin acts as an angiogenesis inhibitor in rat cornea model and in a xenograft tumor model. To additionally prove that maspin is directly involved in the suppression of tumor growth and metastasis, we tested maspin in a new syngeneic mammary tumor model, TM40D. This model involves the implantation of TM40D mammary tumor cells orthotopically to the mammary gland; tumors grew within the gland and then become invasive and metastatic to other organs. Here we demonstrate that TM40D cells in implanted mammary glands are highly invasive. Overall, a 75% rate of invasion and metastasis was observed in this model. However, both primary tumor growth and metastasis were significantly blocked in TM40D cells that overexpress maspin as a consequence of plasmid or retrovirus infection. Maspin-transfected tumors tended to have tumor encapsulation and less necrosis, which were associated with better prognosis and lower invasiveness. Thus, maspin can block primary tumor growth as well as invasion and metastasis. These data support the concept that maspin has a strong protective role against tumor progression.

Abstract
Total hip replacement (THR) is a commonly adopted procedure for arthritis-related diseases. Although the THR efficacy in pain relief and restoration of physical functioning has been extensively studied, it remains unclear how health-related quality of life is affected by THR. The major purpose of this study was to examine and compare the differences in physical functioning and health-related quality of life for THR patients before and after operations. Based on a prospective study design, 46 THR patients at one medical center were reviewed and followed up (six months after operations) during the period from March 1997 to June 1998, with a follow-up rate of 88%. The THR subjects were interviewed and measured by the Modified Harris Hip Scale and the Chinese-version Short-form 36-item Health Survey (SF-36). Patient characteristics and the information related to procedures were derived from chart review. The results indicated that the THR patients had statistically significant improvements in physical functioning and health-related quality of life. In terms of the Harris Score, the mean Harris score was 91.6 (SD = 10.7) 6 months after THR, as compared to 45.2 (SD = 17.3) before THR. The eight ratings in the SF-36 measures were also statistically significantly improved (p < 0.001). Specifically, "role limitations due to physical functioning" demonstrated dramatic improvements after THR (15.2 vs. 63.5), followed by "role limitations due to emotional problems" (25.4 vs. 85.5). The findings confirm the effectiveness of THR outcomes in terms of physical functioning, pain relief, and health-related quality of life, which can be revealed by disease-specific (Harris Scale) and generic health measures (SF-36).

Abstract
Maspin is a unique member of the serpin family, which functions as a class II tumor suppressor gene. Despite its known activity against tumor invasion and motility, little is known about maspin's functions in normal mammary gland development. In this paper, we show that maspin does not act as a tPA inhibitor in the mammary gland. However, targeted expression of maspin by the whey acidic protein gene promoter inhibits the development of lobular-alveolar structures during pregnancy and disrupts mammary gland differentiation. Apoptosis was increased in alveolar cells from transgenic mammary glands at midpregnancy. However, the rate of proliferation was increased in early lactating glands to compensate for the retarded development during pregnancy. These findings demonstrate that maspin plays an important role in mammary development and that its effect is stage dependent.
