Abstract
Immunotherapies targeting programmed cell death protein 1 (PD-1) and its ligand PD-L1 as well as cytotoxic T-lymphocyte-associated protein 4 (CTLA4) have shown impressive clinical outcomes for multiple tumours. However, only a subset of patients achieves durable responses, suggesting incompletely understood mechanisms of the immune checkpoint pathways. Here, we report that PD-L1 translocates from the plasma membrane into the nucleus through interaction with components of endocytosis and nucleocytoplasmic transport pathways, which is regulated by p300-mediated acetylation and HDAC2-dependent deacetylation of PD-L1. Moreover, PD-L1 deficiency leads to compromised expression of multiple immune response-related genes. Genetically or pharmacologically modulating PD-L1 acetylation blocks its nuclear translocation, reprograms the expression of immune response-related genes and consequently enhances the anti-tumour response to PD-1 blockade. Thus, our results reveal an acetylation-dependent regulation of PD-L1 nuclear localization that governs immune response gene expression, thereby advocating for targeting PD-L1 translocation to enhance the efficacy of PD-1/PD-L1 blockade.

Abstract
Background Respiratory viruses (RVs) are among the most common pathogens for both upper and lower respiratory tract infections (RTIs). However, the viral epidemiology of RV-associated RTIs in adults has long been under-recognized. Through a sensitive molecular assay, it would be possible to have a better understanding of the epidemiology of RV-associated RTIs. Material and methods Respiratory tract (RT) specimens from adults hospitalized due to RTIs were tested for RVs, using the multiplex PCR-based Luminex xTAG® Respiratory Viral Panel assay. A total of nineteen RVs, including influenza viruses and non-influenza respiratory viruses (NIRVs) were detected. Positive rates were compared using a chi-square test. Results A total of 2292 samples from adult patients hospitalized with RTIs were screened for RVs. The overall positive rate was 22%, with 17.8% samples positive for at least one NIRV. NIRVs had a higher positive rate in non-winter seasons. As many as 12.7% (46/363) of the samples collected through broncho-alveolar lavage and 20.5% (176/859) of the samples collected in ICUs were positive for RVs. Distribution of corona virus (CoV), human metapneumovirus (hMPV) and parainfluenza virus (PIV) demonstrated seasonal variation. Also, temperature was associated with the positive rates of specific viruses, including CoV, respiratory syncytial virus (RSV), hMPV and PIV. Conclusion Respiratory viruses, notably NIRVs, were frequently detected in adults hospitalized with RTIs. Several RVs were detected with distinctive seasonal variations. A substantial number of RVs were identified in lower RT specimens or from patients admitted to ICU, highlighting their important role in causing severe respiratory infection.

Abstract
OBJECTIVES With the gradual acceptance of robotic-assisted surgery to treat oesophageal cancer and the application of a single-port approach in several abdominal procedures, we adopted a single-port technique in robotic-assisted minimally invasive oesophagectomy during the abdominal phase for gastric mobilization and abdominal lymph node dissection. METHODS Robotic-assisted oesophagectomy and mediastinal lymph node dissection in the chest were followed by robotic-assisted gastric mobilization and conduit creation with abdominal lymph node dissection, which were performed via a periumbilicus single incision. The oesophagogastrostomy was accomplished either in the chest (Ivor Lewis procedure) or neck (McKeown procedure) depending on the status of the proximal resection margin. RESULTS The procedure was successfully performed on 11 patients with oesophageal cancer from January 2017 to December 2018 in our institute. No surgical or in-hospital deaths occurred, though we had one case each of anastomotic leakage, pneumonia and hiatal hernia (9%). CONCLUSIONS Robotic single-incision gastric mobilization for minimally invasive oesophagectomy for treating oesophageal cancer seems feasible. Its value in terms of perioperative outcome and long-term survival results awaits future evaluation.

Abstract
BACKGROUND Chronic hepatitis B virus (HBV) infection is a great health burden with geographical variations. AIMS To explore genetic variants associated with chronic HBV infection. METHODS The study included 15 352 participants seropositive for HBV core antibodies in Taiwan Biobank. Among them, 2591 (16.9%) seropositive for HBV surface antigen (HBsAg) were defined as having chronic HBV infection. All participants were examined for whole-genome genotyping by Axiom-Taiwan Biobank Array. The human leucocyte antigen (HLA) imputation was performed after identification of the variants within the region. Logistic regressions were used to estimate odds ratios (ORs) with 95% confidence intervals. Correlations of different HLA allele frequencies with HBsAg seroprevalence were evaluated across worldwide populations by Pearson correlation coefficients. Epitope prediction was performed for HLA alleles using NetMHCIIpan method. RESULTS Located within a cluster of 450 single nucleotide polymorphisms in HLA class II, rs7770370 (P = 2.73 × 10-35 ) was significantly associated with HBV chronicity (Pcorrected < 8.6 × 10-8 ). Imputation analyses showed that HLA-DPA1*02:02 and HLA-DPB1*05:01 were associated with chronic HBV, with adjusted ORs of 1.43 (1.09-1.89) and 1.61 (1.29-2.01). These allele frequencies were positively correlated with global HBsAg seroprevalence, with R of 0.75 and 0.62 respectively (P < 0.05). HLA-DRB1*13:02, HLA-DQA1* 01:02 and HLA-DQB1*06:09 associated with HBV chronicity negatively, with adjusted ORs of 0.31 (0.17-0.58), 0.70 (0.56-0.87) and 0.33 (0.18-0.63). These HLA alleles had various binding affinities to the predicted epitopes derived from HBV nucleocapsid protein. CONCLUSIONS HLA class II variants are relevant for chronicity after HBV acquisition.

Abstract
Objective: To investigate the novel genetic cause associated with hypospadias and the strategy for preventing offspring genetic defects in these patients. Methods: In March 2019, a patient with gonadal dysplasia (hypospadias associated with cryptorchidism) was referred to Shanghai General Hospital. His secondary sex characters, level of sex hormones and the development of male reproductive system was assessed through physical examination, sex hormone examination, male reproductive system B-ultrasound and computed tomography (CT). Whole-exome sequencing (WES) was preformed to investigate the pathogenic genetic variations associated with hypospadias and cryptorchidism. Also, Sanger sequencing was conducted to verify the WES results in the pedigree. Semen analysis was used to assess the fertility of the proband and the SRD5A2 gene analysis of his spouse was performed to assess the risk of genetic defects in the offspring. Results: The patient suffered from gonadal dysplasia (hypospadias associated with cryptorchidism). Physical examination showed an inverted triangular distribution of pubic hair, small penis and the volume of the testis was 8 ml. Sex hormone examination revealed the level of FSH, LH, Pituitary prolactin (PRL), estrogen (E(2)), testosterone (T), and sex hormone-binding globulin (SHBG) was 25.81 U/L, 10.84 U/L, 21.09 μg/L, 153 pmol/L, 16.95 nmol/L, and 36.15 nmol/L respectively. B-ultrasound and computed tomography (CT) showed left inguinal testis. Also, semen analysis illustrated that the volume was 0.05 ml and sperm concentration<2×10(6)/ml, suggesting oligospermia in this case. WES sequencing and Sanger sequencing showed compound heterozygous LoF mutations in SRD5A2 [NM_000348.3:C.679C>T(p.Arg227Ter) and NM_000348.3:C.16C>T(p.Gln6Ter)] in this patient. And there were no pathogenic genetic variations of SRD5A2 in the spouse. Conclusion: Novel compound heterozygous LoF mutations in SRD5A2[NM_000348.3:C.679C>T(p.Arg227Ter) and NM_000348.3:C.16C>T(p.Gln6Ter)] may be the primary cause of disorders of sex development.

Abstract
Objective: To study the efficacy and safety of low-intensity pulsed ultrasound (LIPUS) at different intervals by mechanical force in treating erectile dysfunction (ED). Method: Forty patients with mild to moderate ED were randomized in a 1∶1 ratio to receive 16-treatment sessions of LIPUS in group A and group B, applied 3 times per week and 2 times per week, respectively. End-point assessments were made at 8th week after treatment. Efficacy were evaluated using International Index of Erectile Function-Erectile Function domain score (IIEF-EF), Erectile Hardness Score (EHS), Self-Esteem and Relationship Questionnaire (SEAR), Sexual Encounter Profile (SEP), Global Assessment Question (GAQ), and pain were assessed by Visual Analogue Score (VAS).Treatment response was confirmed by a minimal clinically importance difference (MCID) at 8th week. Results: Compared with baseline, IIEF-EF score [(17.1±5.48 vs 23.4±3.75, P<0.05) and (18.9±4.34 vs 24.1±4.32, P<0.05)], proportion of EHS 4 [(0 vs 40%, P<0.05) and (16.7% vs 55.6%, P<0.05)], and Overall Relationship score [(50.6 vs 67.5, P<0.05) and (44.4 vs 70.1, P<0.05)] were significantly improved at 8th week in two groups, respectively. Compared with baseline, the positive responses to SEP-3 increased significantly at 8th week in two groups (50.0% vs 80.0%,P<0.05) and (44.4% vs 88.9%, P<0.05), respectively. The positive responses to GAQ-2 were 90.0% and 88.9% at 8th week in two groups, respectively. There were no significant differences in IIEF-EF, EHS, SEAR, SEP and GAQ at 8th week between two groups. There was no significant difference in treatment response using MCID between two groups at end-point (80.5% vs 77.5%). The treatment duration for full sessions were 2.5 weeks less in group A than group B. No adverse effects were reported in all cases. Conclusion: LIPUS at two different intervals is effective and safe for mild to moderate ED, and the regimen at 3 times per week can achieve quite good effect in relatively short duration,while the long-term effects is still be clarified in further study.

Abstract
Abstract
Several genetic variants in the human IFNL3/IFNL4 locus have been associated with reduced hepatic fibrosis despite poor clearance of HCV infection. We expanded this analysis to cirrhosis, a more advanced stage of fibrosis. In 2931 individuals with chronic HCV, the IFNL4 genotype that generates IFN-λ4 was associated with protection from cirrhosis (OR=0.65, p=0.012, adjusted for age and sex). The IFNL4 genotype affects the production of IFN-λ4 and, additionally, may affect expression levels of IFN-λ3, making it difficult to delineate the individual contribution of these IFNs. To address this, we established HepG2-based cell models engineered to inducibly express either IFN-λ3 or IFN-λ4. Using RNA-seq based expression profile generated in these hepatic cell lines, we explored the global transcriptome of liver tumors (n=373) from The Cancer Genome Atlas to identify transcription factor networks affected by these IFNs in the liver. Several networks, including IRF1, were upregulated by IFN-λ4 more strongly than by IFN-λ3. Intracellular expression of IFN-λ4 but not of IFN-λ3 also led to potent IRF1-dependent antiproliferative effects. Live cell imaging revealed that IFN-λ4 was poorly secreted, mainly accumulated in lysosomes, and caused apoptosis, suggesting increased ER-stress via the misfolded protein response. Knockdown of DNA damage-inducible transcript 3 (DDIT3), an ER-stress response effector, significantly attenuated the antiproliferative effects of IFN-λ4. This novel interplay of enhanced IRF1 signaling coupled with intracellular accumulation and induction of ER stress by IFN-λ4 may have complex consequences on liver homeostasis during chronic HCV infection but also mediate anti-cirrhotic phenotypes.

Abstract
BACKGROUND AND AIMS Exposure to metals may promote the risk for cancers. We evaluated the associations of a broad spectrum of metals with gallbladder cancer (GBC) and gallstones. APPROACH AND RESULTS A total of 259 patients with GBC, 701 patients with gallstones, and 851 population-based controls were enrolled in Shanghai, China. A metallome panel was used to simultaneously detect 18 metals in serum through inductively coupled plasma-mass spectrometry. Logistic regression models were used to estimate crude or adjusted odds ratios (ORadj ) with 95% confidence intervals (CIs) for the association between metal levels and gallbladder disease. Among the 18 metals tested, 12 were significantly associated with GBC and six with gallstones (Pcorrected < 0.002). Boron, lithium, molybdenum, and arsenic levels were associated with GBC compared to gallstones as well as with gallstones compared to population-based controls. Elevated levels of cadmium, chromium, copper, molybdenum, and vanadium were positively associated with GBC versus gallstones; and the ORadj for the highest tertile (T3) compared to the lowest tertile (T1) ranged from 1.80 to 7.28, with evidence of dose-response trends (P < 0.05). Arsenic, boron, iron, lithium, magnesium, selenium, and sulfur were inversely associated with GBC, with the T3 versus T1 ORadj ranging from 0.20 to 0.69. Arsenic, boron, calcium, lithium, molybdenum, and phosphorus were negatively associated with gallstones, with the T3 versus T1 ORadj ranging from 0.50 to 0.75 (P < 0.05). CONCLUSIONS Metals were associated with both GBC and gallstones, providing cross-sectional evidence of association across the natural history of disease. Longitudinal studies are needed to evaluate the temporality of metal exposure and gallbladder diseases and to investigate the mechanisms of disease pathogenesis.

Abstract
An imputation algorithm for human leukocyte antigen (HLA) is helpful for exploring novel disease associations. However, population-specific HLA imputation references are essential for achieving high imputation accuracy. In this study, a subset of 1012 individuals from the Taiwan Biobank (TWB) who underwent both whole-genome SNP array and NGS-based HLA typing were used to establish Taiwanese HLA imputation references. The HIBAG package was used to generate the imputation references for eight HLA loci at a two- and three-field resolution. Internal validation was carried out to evaluate the call threshold and accuracy for each HLA gene. HLA class II genes found to be associated with rheumatoid arthritis (RA) were validated in this study by the imputed HLA alleles. Our Taiwanese population-specific references achieved average HLA imputation accuracies of 98.11% for two-field and 98.08% for three-field resolution. The frequency distribution of imputed HLA alleles among 23,972 TWB subjects were comparable with PCR-based HLA alleles in general Taiwanese reported in the allele frequency net database. We replicated four common HLA alleles (HLA-DRB1*03:01, DRB1*04:05, DQA1*03:03, and DQB1*04:01) significantly associated with RA. The population-specific references provide an informative tool to investigate the associations of HLA variants and human diseases in large-scale population-based studies.

Abstract
OBJECTIVE We aimed to evaluate associations of human leukocyte antigen variants with migraine or headache in hospital and population-based settings. METHODS The case-control study population, aged 30-70, included 605 clinic-based migraine patients in a medical center and 8449 population-based participants in Taiwan Biobank (TWB). Clinic-based cases were ascertained by neurologists. Participants in Taiwan Biobank were interviewed by a structured questionnaire including headache and migraine history; among them, 2394 had headache or migraine history while 6055 were free of headache and served as controls. All subjects were genotyped by Axiom Genome-Wide Single Nucleotide Polymorphism Arrays and imputed for eight classical human leukocyte antigen genes. Human leukocyte antigen frequencies were compared between clinic-based and self-reported patients and controls. We utilized likelihood ratio tests to examine human leukocyte antigen-disease associations and logistic regressions to estimate the effect of human leukocyte antigen alleles on migraine. RESULTS Human leukocyte antigen-B and C showed significant associations with clinic-based migraine (q-value < 0.05). Human leukocyte antigen-B*39:01, human leukocyte antigen-B*51:01, human leukocyte antigen-B*58:01 and human leukocyte antigen-C*03:02 were significantly associated with migraine, with age and sex-adjusted odds ratios (95% CIs) of 1.80 (1.28-2.53), 1.50 (1.15-1.97), 1.36 (1.14-1.62) and 1.36 (1.14-1.62), correspondingly. Clinic-based migraineurs carrying human leukocyte antigen-B*58:01 or human leukocyte antigen-C*03:02 had 1.63 (1.11-2.39) -fold likelihood to have chronic migraine with medication-overuse headache compared to episodic migraine. However, no human leukocyte antigen genes were associated with self-reported headache or migraine in the community. CONCLUSIONS Human leukocyte antigen class I genetic variants are positively associated with risk of clinic-based migraine but not self-reported migraine or headache and may contribute to migraine chronification and medication overuse.

Abstract
Objective: To analyze the clinical characteristics and prognostic factors of patients with Hodgkin's lymphoma(HL). Methods: The clinical data of HL patients who were newly treated in Guizhou Cancer Hospital from August 2007 to March 2019 was retrospectively collected, and the efficacy and prognostic factors were analyzed. Results: The clinical data of a total of 222 patients were analyzed in this study. The 5-year progression-free survival (PFS) and overall survival (OS)rate of them were 82.8% and 81.3%, respectively. The 5-year PFS rate and OS rate of early (stage Ⅰ-Ⅱ) HL were 87.3% and 86.1%, respectively, and the 5-year PFS rate and OS rate of progressive (stage Ⅲ-Ⅳ) HL were 77.9% and 76.3%, respectively. Among the 118 patients with early Hodgkin's lymphoma, the complete remission(CR) rate of chemotherapy alone was 55.6%(15/27), and chemotherapy plus radiotherapy was 86.8% (79/91), the difference between which was statistically significant (P<0.05). Compared with chemotherapy plus radiotherapy in early stage patients, 5-year PFS (93.0%) and 5-year OS (92.0%) rate in patients with chemotherapy plus radiotherapy were better than those with chemotherapy alone which were 63.7% and 62.1%, respectively. Multivariate analysis showed that age, LDH, ABVD cycle number and chemoradiotherapy were independent prognostic factors for 5-year OS and PFS rate in HL patients. The adverse reactions were increased level Ⅰ-Ⅱ aminotransferase with an incidence of 47.7% (106/222), decreased level Ⅰ-Ⅱ neutrophils with an absolute value of 54.1% (120/222), and decreased level Ⅲ-Ⅳ neutrophils with an absolute value of 45.9% (102/222). No adverse cardiac and pulmonary reactions or secondary tumors associated with chemotherapy was found in all patients. Conclusions: HL is a type of malignant tumor with good prognosis, and the short-term and long-term efficacy of chemotherapy combined with radiotherapy in early patients is better than that of chemotherapy alone. Age, LDH, ABVD cycle number and chemoradiotherapy are associated with prognosis in patients with Hodgkin's lymphoma. Adverse reactions can be tolerated.

Abstract
Objective: To determine the relationship between volume of epicardial adipose tissue (EAT) and atrial fibrillation (AF) . Methods: A total of 207 patients who hospitalized in the Department of Cardiology, Nantong University Affiliated Hospital from January 2016 to June 2018 were included in this study. They were divided into two groups, including AF group (n=125) and sinus rhythm group (n=82). The AF group included 80 paroxysmal AF (PAF) and 45 persistent AF (PeAF) patients. Total EAT and left atrial EAT (LA-EAT) volume were measured using 256 rows of multi-slice spiral CT in all patients. Echocardiographic derived left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) were analyzed. Hospholipase A2 and blood lipids were examined in all patients. The baseline data and EAT volume of all groups were compared. The multivariate logistic regression was used to analyze the risk factors related to the occurrence of AF. The correlation between total EAT volume and LA-EAT volume and LAD were analyzed by Pearson correlation. Result: The volume of total EAT in patients with sinus rhythm, AF, PAF and PeAF were (92.2±32.1), (136.0±46.0), (134.2±46.3) and (140.1±52.6)cm(3), respectively. The volume of LA-EAT in patients with sinus rhythm, AF, PeAF and PAF were (27.1±7.5), (39.2±19.2), (35.9± 17.0) and (45.1±21.5)cm(3), respectively. Total EAT and LA-EAT volume were significantly larger in PAF and PeAF groups than in sinus rhythm group (all P<0.01). The LA-EAT volume was larger in PeAF group than in PAF group (P<0.01), but total EAT volume was similar between two groups (P>0.05). Logistic regression analysis showed that total EAT volume (OR=1.202, 95%CI 1.083-1.334, P=0.001), LA-EAT volume (OR=1.051, 95%CI 1.003-1.101, P=0.037) and LAD (OR=1.019, 95%CI 1.005-1.032, P=0.006) were the independent related factors of AF. Pearson correlation analysis showed that the total EAT volume was positively correlated with LAD (r=0.466, P<0.01) and LA-EAT volume was positively correlated with LAD (r=0.290, P<0.01). Conclusion: The volume of total EAT and LA-EAT measured by 256-row multi-slice spiral CT is significantly correlated with the incidence of AF.

Abstract
Objective: The aim is to analyze the fracture risk in rheumatic patients by fracture risk assessment tool (FRAX), which is recommended by World Health Organization (WHO), so that we can prevent the occurrence of osteoporotic fracture earlier. Methods: Totally 617 participants, 204 out-patients with rheumatism, 204 in-patients with rheumatism and 209 healthy controls, from March to October in 2018 of Fourth Medical Center of PLA General Hospital, Jishuitan Hospital and China-Japan Friendship Hospital, were enrolled in this study. The probability of hip fracture (PHF) and major osteoporotic fracture (PMOF) in 10 years with FRAX were compared, and the differences between taking sleroids or not and with or without bone mass density (BMD) of femoral neck were evaluated. Correlation analysis was conducted between PHF, PMOF and clinical information, including age, disease duration, gender, steroid usage, osteocalcin, P1NP and β-crosslaps. Results: There was no significant difference in PMOF within 10 years (3.455±2.690 vs 2.973±2.149 vs 3.323±1.828) among the three groups (P>0.05), but the PHF (0.986±1.619 vs 0.515±0.873 vs 0.149±0.311) was different (P<0.05). PHF and PMOF increased gradually with age. PMOF of patients without glucocorticoid therapy in 10 years was lower than that of patients with glucocorticoid (3.554±2.584 vs 2.857±2.238, P<0.05). There is no difference between the results of FRAX calculated with BMD or not (3.012±2.231 vs 3.207±2.601, P>0.05). PHF and PMOF were positively correlated with age, course of disease, glucocorticoid use and osteocalcin level, while PHF was negatively correlated with TP1NP among in-patients. Conclusion: The prevalence of 10-year hip fracture calculated by FRAX in rheumatism patients is higher than that of healthy group. FRAX can be used to calculate fracture risk without BMD. Combination of FRAX and bone turnover markers may be more effective in prediction of osteoporotic fracture in rheumatic patients.

Abstract
Objective: To investigate the morphological features of colorectal sessile serrated adenoma/polyp (SSA/P) and hyperplastic polyp (HP) by white light endoscope (WLE) and Image enhancement endoscope (IEE) . Methods: The data of 7 384 patients who underwent colonoscopy at the Center of Digestive Endoscopy, Peking University International Hospital from August 1, 2016 to February 29, 2018 were analyzed retrospectively. WLE and IEE[Fuji intelligent chromo endoscopy (FICE) or Blue Laser Imaging (BLI) ]were used to compare the morphological features of SSA/P with HP, SSA/P-CD(+)with SSA/P-CD(-). The diagnostic values of endoscopic features in SSA/P and SSA/P-CD(+)were analyzed. Results: A total of 3 401 polyps were detected in 7 384 patients, including 164 SSA/Ps (135 patients). During the same period, there were 270 HPs (223 patients) in accordance with the admission criteria. Compared with HP group, SSA/P group was more common in the right colon with a diameter>5 mm and more likely to be manifested as: Ⅱ-O pit pattern, surface mucus, cumulus-like surface, irregular morphology, VMV, redness, and also more likely to be associated with colon adenoma, colon cancer elsewhere in the colorectum. The differences were statistically significant (P<0.01). Compared with SSA/P-CD(-)group, SSA/P-CD(+)group was more common in the right colon with a diameter>5 mm and more likely to be manifested as: Ⅱ-O pit pattern, surface mucus, cumulus-like surface, irregular morphology, VMV. The differences were statistically significant (P<0.001). The differential diagnosis between SSA/P and HP was predicted by combining any two endoscopic morphological features (right colon, Ⅱ-O pit pattern, surface mucus, cumulus surface, irregular morphology, VMV, diameter>5 mm, at least 2 of 7 endoscopic features). The sensitivity, specificity, accuracy, positive likelihood ratio and negative likelihood ratio were 59.15%, 95.56%, 81.80%, 13.32 and 0.43, respectively. Similarly, the differential diagnosis between SSA/P-CD(+) and HP was predicted. The sensitivity, specificity, accuracy, positive likelihood ratio and negative likelihood ratio were 92.16%, 95.56%, 95.02%, 20.76 and 0.08, respectively. Conclusion: Comprehensive analysis of the WLE and FICE/BLI morphological features of the lesions can effectively distinguish SSA/P from HP, especially SSA/P-CD(+) from HP.

Abstract
Amide bond formation is one of the most important basic reactions in chemistry. A catalyst-free approach for constructing amide bonds from thiocarboxylic acids and amines was developed. The mechanistic studies showed that the disulfide was the key intermediate for this amide synthesis. Thiobenzoic acids could be automatically oxidized to disulfides in air, thioaliphatic acids could be electro-oxidized to disulfides, and the resulting disulfides reacted with amines to give the corresponding amides. By this method, various amides could be easily synthesized in excellent yields without using any catalyst or activator. The successful synthesis of bioactive compounds also highlights the synthetic utility of this strategy in medicinal chemistry.

Abstract
Neutrophil gelatinase-associated lipocalin (NGAL) is a new biomarker for renal injury. It is also involved in tumorigenesis of different human cancer types. The oncogenic role of NGAL is related to its molecular forms, and heterodimer formation with matrix metalloproteinase 9 (MMP9) promotes human breast cancer (HBC) invasion and metastasis. To date, the levels of NGAL and NGAL/MMP9 complex have not yet been explored in canine mammary tumours (CMTs). Hence, this study aimed to investigate whether NGAL and its molecular forms could be the biomarker for CMT diagnosis. To this end, expression profile of NGAL and MMP9 in mammary epithelial cells as well as in urine samples were detected. By immunohistochemistry staining, NGAL was expressed at variable levels. Unlike HBC, a significant reduction in NGAL expression was demonstrated in benign and malignant CMTs as compared with normal controls. Additionally, NGAL expression was significantly reduced in dogs with metastatic CMTs. By contrast, the mean score of MMP9 expression in ascending order was normal groups, benign, and malignant CMTs. Interestingly, analysis of the molecular form revealed the NGAL/MMP9 complex presents in most mammary tissues and urine of dogs with benign or malignant CMTs, whereas the complex was absent in samples from dogs without CMTs. In conclusion, NGAL and MMP9 are ubiquitously expressed in canine mammary epithelial cells in normal and cancerous status. However, the NGAL/MMP9 complex exclusively presents in mammary tissues and urine of dogs with tumours.

Abstract
A variational principle is derived for two-dimensional incompressible rotational fluid flow with a free surface in a moving vessel when both the vessel and fluid motion are to be determined. The fluid is represented by a stream function and the vessel motion is represented by a path in the planar Euclidean group. Novelties in the formulation include how the pressure boundary condition is treated, the introduction of a stream function into the Euler–Poincaré variations, the derivation of free surface variations and how the equations for the vessel path in the Euclidean group, coupled to the fluid motion, are generated automatically.

Abstract
Objective: To discuss the efficacy and safety of subinguinal microsurgical varicocelectomy in the treatment of non-obstructive azoospermia (NOA) with varicocele. Methods: The clinical data of 141 patients with NOA and varicocele who underwent subinguinal microsurgical varicocelectomy from March 2015 to June 2017 in Shanghai General Hospital was collected.One hundred and ten patients suffered from varicocele on the left side, 1 on the right side, and the rest (30 cases) were bilateral varicocele. Grade Ⅰ varicocele were found on 7 sides (the right and left side was count respectively), grade Ⅱ on 121 sides, and grade Ⅲ on 43 sides. Sperm analysis, pregnancy rate and complications were recorded after at least 6 months since operation. Results: Eleven cases were lost during the follow-up. Eighteen of the remaining 130 NOA patients processed successful sperm retrieval in post-operative semen analysis (18/130, 13.8%). Six couples(6/130, 4.6%) succeeded in natural pregnancy. Five couples (5/130, 3.8%)underwent successful pregnancy following with intracytoplasmic sperm injection(ICSI). Twenty-six out of the remaining 112 patients underwent the micro dissection testicular sperm extraction (micro-TESE), and 4 patients got a successful sperm retrieval (4/26, 15.4%). Among them, 2 couples had successful pregnancy with ICSI. Totally 2 cases of postoperative infection of incision were found. Conclusions: Microsurgical varicocelectomy had a beneficial effect on sperm quality of patients suffered from NOA with varicocele to some extent, even leading to unassisted pregnancy or avoiding micro-TESE before ICSI. Microsurgical varicocelectomy could be applied in the treatment of NOA with varicocele.

Abstract
BACKGROUND Despite its high contagiousness, high recurrence rate and potential for malignant transformation, effective treatments for condyloma acuminatum (CA) have not yet been developed. Accordingly, it is necessary to clarify the mechanisms underlying CA development. AIM To investigate the expression and significance of the proteins Wnt-1 and TSLC1 in patients with CA and in normal foreskin controls. METHODS Wnt-1 and TSLC1 were assessed by immunohistochemistry in 45 patients with CA. RESULTS Positive expression rates of Wnt-1 and TSLC1 were 82.22% (37/45) and 37.78% (17/45), respectively, in CA tissues, and 29.17% (7/24) and 91.67% (22/24), respectively, in normal foreskin controls. Wnt-1 expression intensity in CA was markedly higher (positive to strongly positive) than that in normal controls (negative to weakly positive), whereas TSLC1 expression intensity ranged from weakly positive to positive in CA, and nearly strongly positive in the normal control group. The differences in the positive expression rate and expression intensity of Wnt-1 and TSLC1 between the two groups were statistically significant (P < 0.05). In addition, Wnt-1 and TSLC1 were negatively correlated. (r = -0.336, P < 0.05). CONCLUSIONS Overexpression of Wnt-1 and low expression of TSLC1 may be associated with the growth of CA. These findings may provide a basis for the development of therapies to prevent recurrence or malignant transformation of CA.

Abstract
OBJECTIVE To evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) and endoscopic submucosal excavation (ESE) for upper gastroenterology submucosal tumors (SMT) originating from the muscularis propria (MP) layer. METHODS Clinicopathological and endoscopic data of 42 cases with upper gastroenterology tumors originating from the MP layer who were treated with STER (n=28) or ESE (n=14) between April 2013 and December 2016 in Peking University Third Hospital were retrospectively analyzed. The treatment and complications of the two groups were compared. RESULTS In the study, 42 cases were all resected by therapeutic endoscopy successfully.There was no significant difference (STER vs. ESE) in gender, age, mean tumor size [1.5 (1.0-6.0) cm vs. 1.3 (0.5-2.0) cm, P=0.056]. STER was superior to ESE with reduced sutured time [3.5 (1.0-11.0) min vs. 8.0 (2.0-33.0) min, P=0.006], but more resection time [46.5 (11.0-163.0) min vs.19.5 (6.0-56.0) min, P=0.007]. There was statistical difference between the two groups in resection time or sutured time, but no significant difference (STER vs. ESE) in total operative time [52.0 (14.0-167.0) min vs. 31.5 (10.0-88.0) min, P=0.080]. En bloc resection rates (92.9% vs. 85.7%), hospital stay duration and complications (10.7 vs. 0.0) were similar in the STER and ESE groups. One case developed mediastinal emphysema and 2 pneumonia after operation in STER group, and all of them recovered uneventfully after conservative treatments; There were no complications in the ESE group. After operation, 28 cases of leiomyoma and 14 cases of stromal tumor were diagnosed by routine pathological and immunohistochemical staining. Among them, 6 cases of stromal tumors in group STER were all extremely low risk, 4 cases of stromal tumors in group ESE were extremely low risk, 4 cases of stromal tumors in group ESE were medium risk (the size of the lesion was about 1.0-2.0 cm, and mitotic figures counted (6-8)/50 high power field). The median follow-up time of all the patients was 46.5 (24-60) months, and the shortest follow-up time for medium risk stromal tumors was 32 months. No residual tumor, recurrence and implantation in the tunnel were observed. CONCLUSION STER or ESE can be used as an effective and safe option for treatment of submucosal tumors originating from the muscularis propria of the upper digestive tract. Compared with STER, ESE had shorter resection time but longer wound closure time. There was no significant difference in total operation time.

Abstract
In low-dose CT screening era, an ideal preoperative localization method is essential for resection of small and deep-seated pulmonary nodules by video-assisted thoracoscopic surgery (VATS). This article focuses on intraoperative ultrasonography localization method during thoracoscopy. Performing ultrasonography intraoperatively is a real-time and alternative approach to localize small, non-visible and non-palpable pulmonary lesions without injury to lung parenchyma. Its widespread usage has been limited due to the air in the lung parenchyma; however, its application can be useful in some conditions with guidance to find the lesion.

Abstract
The Mixed Lineage Leukemia gene (MLL) is altered in leukemia by chromosomal translocations to produce oncoproteins composed of the MLL N-terminus fused to the C-terminus of a partner protein. Here, we used domain-focused CRISPR screening to identify ZFP64 as an essential transcription factor in MLL-rearranged leukemia. We show that the critical function of ZFP64 in leukemia is to maintain MLL expression via binding to the MLL promoter, which is the most enriched location of ZFP64 occupancy in the human genome. The specificity of ZFP64 for MLL is accounted for by an exceptional density of ZFP64 motifs embedded within the MLL promoter. These findings demonstrate how a sequence anomaly of an oncogene promoter can impose a transcriptional addiction in cancer.

Abstract
Objectives Wisteria floribunda agglutinin-positive human Mac-2-binding protein (WFA+-M2BP) is a glycomarker. The present community-based long-term follow-up study repeatedly determined the serum WFA+-M2BP level and examined its short- and long-term associations with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). Methods A total of 921 participants with antibodies against HCV seropositive, but seronegative for hepatitis B surface antigen were enrolled from seven townships in Taiwan during 1991–1992. The participants were regularly followed and their serum WFA+-M2BP levels were measured at baseline and follow-up. HCC was ascertained through active follow-up and computerized data linkage with the National Cancer Registration System until December 31, 2013. Cox proportional hazards and logistic regression models were applied to estimate the magnitude of associations between serum WFA+-M2BP levels and HCC. Results During a median follow-up of 21.7 years, 122 new-onset HCC cases were identified. Elevated serum WFA+-M2BP levels were associated with an increased risk of HCC (p < 0.001). Patients with increasing changes in serum WFA+-M2BP levels, relative to their baseline levels, had a 4.36-fold risk of HCC. The areas under receiver operating curves (AUROCs) of WFA+-M2BP for predicting HCC showed that the prediction efficacy was significantly higher while closer to HCC diagnosis (p = 0.024). The AUROC was 0.91 for predicting HCC within 1 year by including the predictors of age, sex, alanine aminotransferase, alpha-fetoprotein (AFP) and WFA+-M2BP. Conclusions Serum WFA+-M2BP level may elevate before HCC onset and is a short-term predictor of HCC among patients infected with HCV.

Abstract
Objective: To compare the effect of cold snare and hot snare on the resection of small colorectal polyps, and to explore the clinical value of cold snare technique in removing colorectal polyps. Methods: From September 1, 2017 to January 31, 2018, 206 cases of patients with colorectal polyp resection in the Department of Gastroenterology of Peking University International Hospital were studied. During this period, according to the standard, 103 cases of patients (158 polyps) were in the cold snare group, and 103 patients (180 polyps) were randomly selected as control group from patients of the hot snare group. The related clinical data were analyzed retrospectively. The location, shape, size, polypectomy time, pathological type, complete resection rate, specimen recovery rate, complications and related costs of the two groups of polyps were compared. Results: The polypectomy time of the cold snare group was shorter than that of the hot snare group.The difference was statistically significant (Z=-11.727, P<0.001). The related cost of the perioperative period of the cold snare group was lower than that of the hot snare group.The difference was statistically significant (Z=-12.680, P<0.001). There were no statistically significant differences in the number of polyps/case, size, shape, pathological classification, complete resection rate, specimen recovery rate, and perioperative complications of the patients in the two groups(P>0.05). Conclusions: The operation time of cold snare technique in colorectal polyps (6-9 mm in diameter) is shorter and the cost is lower, which is worthy of clinical promotion.

Abstract
Small cell lung cancer (SCLC) is widely considered to be a tumor of pulmonary neuroendocrine cells; however, a variant form of this disease has been described that lacks neuroendocrine features. Here, we applied domain-focused CRISPR screening to human cancer cell lines to identify the transcription factor (TF) POU2F3 (POU class 2 homeobox 3; also known as SKN-1a/OCT-11) as a powerful dependency in a subset of SCLC lines. An analysis of human SCLC specimens revealed that POU2F3 is expressed exclusively in variant SCLC tumors that lack expression of neuroendocrine markers and instead express markers of a chemosensory lineage known as tuft cells. Using chromatin- and RNA-profiling experiments, we provide evidence that POU2F3 is a master regulator of tuft cell identity in a variant form of SCLC. Moreover, we show that most SCLC tumors can be classified into one of three lineages based on the expression of POU2F3, ASCL1, or NEUROD1. Our CRISPR screens exposed other unique dependencies in POU2F3-expressing SCLC lines, including the lineage TFs SOX9 and ASCL2 and the receptor tyrosine kinase IGF1R (insulin-like growth factor 1 receptor). These data reveal POU2F3 as a cell identity determinant and a dependency in a tuft cell-like variant of SCLC, which may reflect a previously unrecognized cell of origin or a trans-differentiation event in this disease.

Abstract
Objective: To investigate the clinicopathological features of EBV-positive T/NK cell lymphoproliferative diseases (EBV(+) T/NK-LPD). Methods: The clinical characteristics of 156 cases of EBV(+) T/NK-LPD were collected from August 2002 to March 2015 at Beijing Friendship Hospital, Capital Medical University. Immunohistochemical staining, EBER in situ hybridization and clonal analysis of TCR gene were performed. All patients were followed up. Results: There were 106 male and 50 female patients; patients' age ranged from 1 to 75 years (median 20 years). The course of the diseases before diagnosis ranged from 2 to 540 months (median 20 months). Fever was noted in 122 patients (78.2%), 108 patients had lymphadenopathy (69.2%), and 75 patients had hepatosplenomegaly (48.1%). Thirty-three cases were grade 1, 68 cases were grade 2, and 55 cases were grade 3. TCR gene arrangement analysis was performed in 45 cases, and 33 cases (73.3%) showed clonal rearrangement. The follow-up period ranged from 1-134 months, and 44 patients (28.2%) died. There was a trend of increased death rate associated with increasing grade (P>0.05). Conclusions: There are many types of EBV(+) T/NK-LPD, and they can be classified as systemic, relatively localized and localized. The prognosis should be based on a comprehensive analysis of pathology and clinical data. There is no significant correlation between morphological grade and mortality. An important goal of therapy is to prevent serious complications.

Abstract
Objective: To observe the clinical efficacy and safety of the LOP regimen (L-asparaginase, vincristine, dexamethasone) combined with intensity modulated radiation therapy(IMRT)in the treatment of early nasal NK/T cell lymphoma. Method: Clinical data of 65 patients with nasal NK/T cell lymphoma treated with LOP chemotherapy combined with IMRT at the Guizhou Province Tumor Hospital between March 2010 and January 2015 were retrospectively analyzed. Results: Among the 65 patients, 39 cases obtained complete remission (CR), 18 cases obtained partial remission(PR), 1 case obtained stable disease (SD), 7 cases had progressive disease(PD). The objective response rate (ORR) was 87.7%, the disease control rates (DCR) was 89.2%. The DCR was lower in the patients with B symptoms or over age of 60. Patients with super cavity obtained a worse progression-free survival(PFS). The 1-, 2-, 3-year PFS were 91.7%, 74.8% and 61.3%, the overall survival(OS) were 91.8%, 81.3% and 78.9%, respectively. Main adverse reactions were myelosuppression, gastrointestinal reaction, hepatic lesion, hypoproteinemia, percutaneous reaction and oral mucosa reaction. No severe pancreatitis, severe anaphylaxis and toxic related death were observed. Conclusion: The LOP regimen combined with IMRT treatment for nasal NK/T cell lymphoma may have a good therapeutic effect, low toxicity, and good tolerance.

Abstract
Objective: To prospectively investigate the changes in nutritional status of patients with malignant tumors during hospitalization by using nutritional risk screening (NRS2002), and to analyze the correlation between the nutritional status and clinical outcomes . Methods: This was a prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014.Hospitalized patients with malignant tumors inthese departments (Department of Gastroenterology, respiratory medicine, oncology, general surgery, thoracic surgery and geriatrics)were investigated. Only the patients with age≥ 18 years and hospitalization time between 7-30 days were included. During hospitalization, the physical indexes of human bodywere measured, and the NRS 2002 scores, and monitored the nutritional support at the time points of admission and 24 hours before discharge were recorded.And whether there was a nutritional risk in hospitalized patients and its association with clinical outcomes were investigated. Results: A total of 2 402 patients with malignancies were enrolled in this study. Seventy fourpatients who did not complete NRS2002 were eliminated, and 2 328 patients were included. The number of the main diseases was the top five, including 587 cases of colorectal cancer, 567 cases of lung cancer, 564 cases of gastric cancer, 146 cases of esophageal cancer, and 119 cases of liver tumor. At the time of discharge, compared with admission, the BMI, body weight, grip and calf circumferences of patients with malignant tumor were significantly decreased (P<0.05). The total protein, albumin, prealbumin and hemoglobin were significantly lower than those at admission (P<0.05). In 2 328 patients who were completed nutritional risk screening, the rate of malnutrition at admission was 11.1% (BMI =18.5, 258/2 328) and the rate of malnutrition at discharge was 10.9% (BMI =18.5, 254/2 328), there were no significant differences (χ(2)=0.019 7, P=0.888). There were 1 204 patients with nutritional risk at admission (51.7%, NRS2002 score≥3)and 1 352 patients with nutritional risk at discharge (58.1%, NRS2002 score≥3), with significant differences (χ(2)=49.9, P<0.001). The incidence of nutritional risk in patients with colorectal, stomach, and lung tumors at discharge was significantly higher than that at admission (P<0.05). The infective complications and other complications of patients with nutritional risk were significantly greater than those without nutritional risk at admission and at discharge.ICU hospitalization stay of patients with nutritional risk was increased significantly than those without nutritional risk at admission(P=0.042). Hospitalization expenses of patients with nutritional risk was increased significantly than those of patients without nutritional risk at discharge(P<0.01). Conclusion: The patients with malignant tumor have a higher incidence rate of malnutrition at both admission and discharge and malnutritionhas correlation with adverse clinical outcomes.The aboveindicators did not improve significantly at discharge.Doctors should pay more attention to the nutritional status (screening and evaluation)of patients before discharge and use appropriate and adequate nutrition support in order to prevent the weight loss and improve the life quality of patients.

Abstract
Objective: To evaluate the efficacy and safety of microsurgical crossover vasovasostomy in treating complicated obstructive azoospermia. Methods: The data of 14 patients with complicated obstructive azoospermia treated with microsurgical crossover vasovasostomy were reviewed from October 2012 to March 2016.Ten of them underwent microsurgical crossover vasovasostomy. Intraoperative exploration revealed that 2 patients had vas deferens injury and contralateral testicular atrophy or epididymal obstruction due to previous hernia repair; 7 patients had obstruction of intracorporeal vas deferens on one side and epididymal obstruction on the other side; the other 1 patient had unilateral vasal obstruction with contralateral epididymal obstruction. Furthermore, 4 patients underwent microsurgical crossover vasoepididymostomy, including 3 patients who had obstruction at caput epididymis on one side, and obstruction at cauda epididymis and distal vas deferens on the other side; the other patient had absence of vas deferens in the scrotum on one side, and testicular atrophy on the other side. Regular follow-up visits were conducted after the surgery. Results: Two patients were lost to follow-up; the other 12 patients were follow-up for an average of 11 (range: 2-23) months. In the 10 cases receiving microsurgical crossover vasovasostomy (including 2 patients lost to follow-up), 1 has not undergone semen re-analysis, 6 were confirmed patent, including 3 reporting spontaneous pregnancy. The patency rate in the 4 patients receiving microsurgical crosseover vasoepididymostomy was 2/4, with 1 patient reporting spontaneous pregnancy. There was no complaint of discomfort or complications following the surgery. Conclusions: Microsurgical crossover anastomosis may be effective and safe for patients with complicated obstructive azoospermia, according to preoperative assessment and intraoperative exploration. It allows natural conception for patients with refractory infertility. The microsurgical crossover anastomosis could be an effective therapy to achieve satisfactory patency of vas deferens.

Abstract
The lineage-specific transcription factor (TF) MEF2C is often deregulated in leukemia. However, strategies to target this TF have yet to be identified. Here, we used a domain-focused CRISPR screen to reveal an essential role for LKB1 and its Salt-Inducible Kinase effectors (SIK3, in a partially redundant manner with SIK2) to maintain MEF2C function in acute myeloid leukemia (AML). A key phosphorylation substrate of SIK3 in this context is HDAC4, a repressive cofactor of MEF2C. Consequently, targeting of LKB1 or SIK3 diminishes histone acetylation at MEF2C-bound enhancers and deprives leukemia cells of the output of this essential TF. We also found that MEF2C-dependent leukemias are sensitive to on-target chemical inhibition of SIK activity. This study reveals a chemical strategy to block MEF2C function in AML, highlighting how an oncogenic TF can be disabled by targeting of upstream kinases.

Abstract
We conducted a genome-wide association study to discover genetic variants associated with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). We genotyped 502 HCC cases and 749 non-HCC controls using the Axiom-CHB genome-wide array. After identifying single-nucleotide polymorphism clusters located in the human leukocyte antigen (HLA) region which were potentially associated with HCC, HLA-DQB1 genotyping was performed to analyze 994 anti-HCV seropositives collected in the period 1991-2013 in a community-based cohort for evaluating long-term predictability of HLA variants for identifying the risk of HCC. Cox proportional hazards models were used to estimate the hazard ratios and 95% confidence intervals of HLA genotypes for determining the aforementioned HCC risk. Eight single-nucleotide polymorphisms in the proximity of HLA-DQB1 were associated with HCC (P < 8.7 × 10-8 ) in the genome-wide association study. Long-term follow-up showed a significant association with HLA-DQB1*03:01 and DQB1*06:02 (P < 0.05). The adjusted hazard ratios associated with HCC were 0.45 (0.30-0.68) and 2.11 (1.34-3.34) for DQB1*03:01 and DQB1*06:02, respectively. After stratification by HCV genotypes, DQB1*03:01 showed protective effects only in patients with HCV genotype 1, whereas DQB1*06:02 conferred risk of HCC only in patients with HCV non-1 genotypes. HLA imputation analyses revealed that HLA-DRB1*15:01, which is in linkage disequilibrium with DQB1*06:02, also increased the risk of HCC (odds ratio, 1.96; 95% confidence interval, 1.31-2.93). Haplotype analysis supported that DQB1*03:01 and DQB1*06:02 are primarily protective and susceptible variants, respectively. Conclusion: HLA-DQB1 was independently associated with HCC; HCV genotypes modified the effects of HLA-DQB1 on the risk of HCC. (Hepatology 2018;67:651-661).

Abstract
Targeting of general coactivators is an emerging strategy to interfere with oncogenic transcription factors (TFs). However, coactivator perturbations often lead to pleiotropic effects by influencing numerous TFs. Here we identify TAF12, a subunit of TFIID and SAGA coactivator complexes, as a selective requirement for acute myeloid leukemia (AML) progression. We trace this dependency to a direct interaction between the TAF12/TAF4 histone-fold heterodimer and the transactivation domain of MYB, a TF with established roles in leukemogenesis. Ectopic expression of the TAF4 histone-fold fragment can efficiently squelch TAF12 in cells, suppress MYB, and regress AML in mice. Our study reveals a strategy for potent MYB inhibition in AML and highlights how an oncogenic TF can be selectively neutralized by targeting a general coactivator complex.

Abstract
Treatments that target immune checkpoints, such as the one mediated by programmed cell death protein 1 (PD-1) and its ligand PD-L1, have been approved for treating human cancers with durable clinical benefit. However, many patients with cancer fail to respond to compounds that target the PD-1 and PD-L1 interaction, and the underlying mechanism(s) is not well understood. Recent studies revealed that response to PD-1-PD-L1 blockade might correlate with PD-L1 expression levels in tumour cells. Hence, it is important to understand the mechanistic pathways that control PD-L1 protein expression and stability, which can offer a molecular basis to improve the clinical response rate and efficacy of PD-1-PD-L1 blockade in patients with cancer. Here we show that PD-L1 protein abundance is regulated by cyclin D-CDK4 and the cullin 3-SPOP E3 ligase via proteasome-mediated degradation. Inhibition of CDK4 and CDK6 (hereafter CDK4/6) in vivo increases PD-L1 protein levels by impeding cyclin D-CDK4-mediated phosphorylation of speckle-type POZ protein (SPOP) and thereby promoting SPOP degradation by the anaphase-promoting complex activator FZR1. Loss-of-function mutations in SPOP compromise ubiquitination-mediated PD-L1 degradation, leading to increased PD-L1 levels and reduced numbers of tumour-infiltrating lymphocytes in mouse tumours and in primary human prostate cancer specimens. Notably, combining CDK4/6 inhibitor treatment with anti-PD-1 immunotherapy enhances tumour regression and markedly improves overall survival rates in mouse tumour models. Our study uncovers a novel molecular mechanism for regulating PD-L1 protein stability by a cell cycle kinase and reveals the potential for using combination treatment with CDK4/6 inhibitors and PD-1-PD-L1 immune checkpoint blockade to enhance therapeutic efficacy for human cancers.

Abstract
Evidence on whether patients with psoriasis have a higher risk for staphylococcal colonization than healthy controls remains controversial. To synthesize the current literature, we performed a systematic review on the prevalence and relative risk (RR) of Staphylococcus aureus colonization in patients with psoriasis. We modified the QUADAS-2 instrument to assess the reporting quality of individual studies and applied random-effects models in meta-analysis. Overall we identified 21 eligible studies, of which 15 enrolled one or more comparison groups. The pooled prevalence of staphylococcal colonization in patients with psoriasis was 35·3% [95% confidence interval (CI) 25·0-45·6] on lesional skin and 39·2% (95% CI 33·7-44·8) in the nares. Patients with psoriasis were 4·5 times more likely to be colonized by S. aureus than healthy controls were on the skin (RR 5·54, 95% CI 3·21-9·57) and 60% more in the nares (RR 1·60, 95% CI 1·11-2·32). Cutaneous and nasal colonization by meticillin-resistant S. aureus also appeared higher in patients with psoriasis (pooled prevalence 8·6%) than in healthy controls (2·6%), yet the difference was not statistically significant (P = 0·74). In contrast, despite of a similar risk for nasal staphylococcal colonization (RR 0·67, 95% CI 0·38-1·18), patients with psoriasis were less likely to carry S. aureus on lesional skin than atopic patients (RR 0·64, 95% CI 0·40-1·02). In summarizing the current literature, we found that patients with psoriasis were at an increased risk for staphylococcal colonization compared with healthy individuals. Prospective studies on how bacterial loads correlate with disease activity can guide the clinical management of bacterial colonization while preventing the emergence of drug-resistant strains.

Abstract
Background Frontal fullness in Asians is often considered to indicate one’s public popularity and leadership skills. Numerous materials and techniques have been applied clinically to recontour or volumize the frontal area, with variable results. The micro-autologous fat transplantation (MAFT) technique proposed by Lin et al. (2nd academic congress of Taiwan Cosmetic Association Taipei,
Taiwan) in 2007 has demonstrated its feasibility in facial rejuvenation. In the present study, we used an innovative instrument to apply the MAFT technique to frontal augmentation with fat grafting and reported the results. Methods MAFT was performed on 178 patients (167 female, 11 male) during a 5-year period starting in January 2010. Fat was harvested by liposuction, processed and refined by centrifugation at 1200×g for 3 min. The purified fat was micro-transplanted for frontal contouring with the assistance of an instrument, the MAFT-GUN. The patients were followed up regularly, and photographs were taken for comparison. Results On average, the MAFT procedure took 52 min to complete. The average amount of delivered fat was 10.2 mL. The follow-up period was 34 months on average. No complications, including neurovascular injury, skin necrosis, abscess, nodulation, calcification or irregularity, were noted. A patient-rated satisfaction 5-point Likert scale demonstrated that 83.1% of all patients had favorable results (48.3% were satisfied, and 34.8% were very satisfied). Conclusion The concept and technique of MAFT has changed fat grafting from an operation with unpredictable clinical results to an easy, reliable and consistent procedure. Furthermore, the use of a precisely controlled instrument enabled surgeons to perform highly accurate micro-fat grafting. In comparison with other strategies for volume restoration, the MAFT procedure demonstrated high patient satisfaction with the long-term results. Therefore, the use of MAFT as an alternative approach to forehead contouring and volumizing was addressed.

Abstract
In recent years, there are increasing articles concerning Epstein-Barr virus associated lymphoproliferative disorder (EBV+ LPD), and the name of EBV+ LPD is used widely. However, the meaning of EBV+ LPD used is not the same, which triggered confusion of the understanding and obstacles of the communication. In order to solve this problem. Literature was reviewed with combination of our cases to clarify the concept of EBV+ LPD and to expound our understanding about it. In general, it is currently accepted that EBV+ LPD refers to a spectrum of lymphoid tissue diseases with EBV infection, including hyperplasia, borderline lesions, and neoplastic diseases. According to this concept, EBV+ LPD should not include infectious mononucleosis (IM) and severe acute EBV infection (EBV+ hemophagocytic lymphohistiocytosis, fatal IM, fulminant IM, fulminant T-cell LPD), and should not include the explicitly named EBV+ lymphomas (such as extranodal NK/T cell lymphoma, aggressive NK cell leukemia, Burkitt lymphoma, and Hodgkin lymphoma, etc.) either. EBV+ LPD should currently include: (1) EBV+ B cell-LPD: lymphomatoid granulomatosis, EBV + immunodeficiency related LPD, chronic active EBV infection-B cell type, senile EBV+ LPD, etc. (2) EBV+ T/NK cell-LPD: CAEBV-T/NK cell type, hydroa vacciniforme, hypersensitivity of mosquito bite, etc. In addition, EBV+ LPD is classified, based on the disease process, pathological and molecular data, as 3 grades: grade1, hyperplasia (polymorphic lesions with polyclonal cells); grade 2, borderline (polymorphic lesions with clonality); grade 3, neoplasm (monomorphic lesions with clonality). There are overlaps between EBV+ LPD and typical hyperplasia, as well as EBV+ LPD and typical lymphomas. However, the most important tasks are clinical vigilance, early identification of potential severe complications, and treating the patients in a timely manner to avoid serious complications, as well as the active treatment to save lives when the complications happened.

Abstract
Objective: To evaluate the efficacy of PVD chemo-regimen (Pegaspargase, vincristine and dexamethasone) combined with intensity-modulated radiotherapy (IMRT) for patients with early-stage extranodal nasal NK/T-cell lymphoma (ENKL). Methods: Clinical data of 52 patients with early-stage ENKL were collected during May 2010 and June 2015 in Department of Lymphoma, Cancer Hospital of Guizhou Medical University, and these patients firstly received a concurrent chemoradiotherapy of two-cycle of PVD and IMRT (gross tumor volume primary: 12.6-59.4 Gy) and then 2 to 4 cycles of PVD as subsequent chemotherapy, the efficacy and adverse responses were retrospectively analyzed and observed. Results: Follow-up stopped until December 2015, complete remission was seen in 44 cases (84.6%) and partial remission 7 cases (13.5%), out of 52 cases. A total of 1 case died of progression disease during treatment and within 1 year after treatment, 1 case died of pulmonary infection within 1 week after treatment, 2 cases survived with tumor; so the objective response rate and clinical benefit rate were both 98.1%, 1-year, 2-year and 3-year overall survival rates and progression free survival rates were all 93.6%, 1-year and 2-year disease free survival rates were both 90.3%; the correlation analysis showed that the radiotherapy dose was related to the curative effect (P<0.05). Short term adverse responses were observed in 6 cases (11.5%) with grade 3 leucocytopenia, in 5 cases (9.6%) with grade 3-4 dyslipidemia and in 2 cases (3.8%) with grade 3 hypoalbuminemia during chemoradiotherapy. All the patients had different degrees of radiation oral mucositis and radiation dermatitis. Conclusion: For early-stage ENKL, a concurrent chemoradiotherapy of PVD regimen and IMRT have a good therapeutic effect and adverse response can be tolerated.

Abstract
Objectives We investigated the relationships of cystic nodal metastasis, human papillomavirus (HPV) status, and treatment failure patterns in patients with oropharyngeal squamous cell carcinoma (OPSCC) treated with chemoradiotherapy. Methods We retrospectively reviewed pretreatment MRI and clinical courses of patients with OPSCC whose tumors were tested for HPV-induced p16 expression via immunohistochemistry and who completed chemoradiotherapy. Cervical cystic nodal metastasis and necrotic nodal metastasis were classified on MRI. Results Of 98 patients eligible for analysis, 33 were p16-positive. Cystic nodal metastasis was significantly more prevalent in p16-positive than in p16-negative patients (39.4% versus 18.5%, respectively; p = 0.025). Necrotic nodal metastasis was significantly more prevalent in p16-negative than in p16-positive patients (73.8% versus 51.5%, respectively; p = 0.027). On multivariate analysis, necrotic nodal metastasis (odds ratio [OR] = 7.310, p = 0.011) was an independent predictor of regional failure, while advanced nodal stage (OR = 4.119, p = 0.022) and cystic nodal metastases (OR = 0.087, p = 0.026) were independent positive and negative predictors of distant failure, respectively. Conclusions Cervical cystic and necrotic nodal metastases are associated with HPV-induced p16-positive and p16-negative OPSCC, respectively. Patients with necrotic nodal metastasis at presentation have an increased risk of regional failure. Distant failure is directly and inversely correlated with advanced nodal stage and cystic nodal metastasis, respectively.

Abstract
Abstract
The transcription factor PITX2 (paired-like homeodomain 2) is well known to play an essential role in normal embryonic development. Emerging evidence suggests that PITX2 may be involved in human tumorigenesis. However, the functional role that PITX2 plays in tumor progression remain unclear. In this study, we investigated its function in human non-small cell lung carcinoma (NSCLC). Using real-time quantitative RT-PCR, we demonstrated that PITX2B is the most abundant isoform in lung cancer cells. Enforced expression of PITX2B could promote lung cancer cell morphological change, migration, invasion, anchorage-dependent growth ability and tumorigenesis in xenograft model mice. In addition, nuclear PITX2B localization was correlated with its oncogenic functions and two important nuclear localization signals (NLSs) were identified. Moreover, high expression of PITX2B was associated with poor overall survival (P<0.05) in NSCLC patients. Importantly, silencing of PITX2B by siRNA caused a marked increase in autophagy based on LC3-II, Beclin-1, and p62 protein expression, acridine orange fluorescence of acidic vacuoles and electron microscopic detection of autophagosomes. Furthermore, we found that the autophagy induced by PITX2B knockdown preceded apoptosis in lung cancer cells. Treatment of lysosome inhibitor, NH4Cl, could provide a protective effect that increases cell viability. In conclusion, our studies not only provide new insights into how PITX2B may contribute to the tumor progression in lung cancer but also the autophagy induced by PITX2B knockdown that may be developed as an effective therapeutic strategy for the treatment of lung cancer.

Abstract
We have designed and fabricated high-performance single-photon avalanche diodes (SPADs) by using 0.18-µm high-voltage CMOS technology. Without any technology customization, the SPADs have low dark-count rate, high photon-detection probability, low afterpulsing probability, and acceptable timing jitter and breakdown voltage. Our design provides a low-cost and high-performance SPAD for various applications.

Abstract
Objective: To analyze the correlation between anatomy of spermatic vessels and varicocele, providing reference for the preoperative assessment and treatment of varicocele. Methods: A total of 156 patients who underwent microsurgical left subinguinal varicocelectomy at Shanghai General Hospital between May 2015 and July 2016 were included in this study. The severity of varicocele and number of spermatic vessels detected in operations were recorded. According to the number of internal spermatic arteries (ISAs), the patients were divided into three groups: single-ISA group (55 cases), double-ISAs group (63 cases) and multi-ISAs group (38 cases), to analyze the correlation among spermatic vessels and to compare varicocele grade, the volume of testes, the parameter of semen analysis, serum reproductive hormone, surgery time, and hospital stay among the three groups. Results: The number of ISAs was positively correlated with the ipsilateral internal spermatic veins (ISVs) (r=0.210; P=0.008)and lymphatic vessels (r=0.224; P=0.005); the number of lymphatic vessels was positively correlated with the ipsilateral gubernacular veins (r=0.172; P=0.032)and ISVs (r=0.296; P=0.000) . The number of ISVs in the multi-ISAs group (10.58±4.28) was significantly larger than that in the single-ISA group (8.22±3.10, P=0.003). The number of lymphatic vessels in the multi-ISAs group(4.11±1.90)was also significantly larger than that in the double-ISA group(3.76±1.40, P=0.020) and the single-ISA group(3.13±1.52, P=0.007). The number of ISVs in grade 2 varicocele patients (9.74±3.90) was significantly higher than that in grade 3 varicocele patients (8.33±3.10, P=0.013). No significant differences in varicocele grade, change of pre- and post-operative semen analysis, serum reproductive hormone, the volume of ipsilateral testes, surgery time, and hospital stay were observed among the three groups. Conclusions: There is a correlation among various kinds of spermatic vessels. Patients with grade 2 varicocele, especially who have multiple ISAs, are likely to have more ISVs and lymphatic vessels. For these patients, surgeons should pay more attention to protect spermatic arteries and lymphatics carefully while ligating varicose veins completely to prevent recurrence and complications.
