Abstract
Bronchial asthma is a common chronic respiratory disease, which is involved in a variety of cells and cellular components. In 2019, the guidelines for the diagnosis and treatment of asthma issued by the Global Initiative for Asthma (GINA) Committee put forward the concept of type 2 inflammatory asthma for the first time. The updated evolution of GINA guidelines has promoted the development of biological agents and disease treatment, providing effective prevention and treatment for patients with severe asthma and improving disease outcome. This paper expounds the disease mechanism and management suggestions of type 2 inflammatory asthma in GINA guidelines, and analyzes the relevant clinical studies on targeted treatment of type 2 inflammatory asthma in recent years, in order to provide reference for in-depth understanding of level 3 prevention and management of patients with type 2 inflammatory asthma.

Abstract
Utilization of sewage sludge for the fabrication of environmental functional materials is highly desirable to achieve pollution mitigation and resource recovery. In the present work, we introduced a novel MgAl-layered double oxide (LDO)@biochar composite adsorbent in-situ fabricated from Al-rich sewage sludge, and its excellent application in nanoplastics adsorption. Initially, fifteen model contaminants with varied conjugate structures, hydrogen bonding and ionic properties were selected for an investigation of adsorption behavior and adsorption selectivity on LDO@biochar. Structural variation of LDO@biochar suggested reconstruction of the layered double hydroxide (LDH) during the adsorption process due to the "memory effect". Under the synergy of LDH and biochar, the contaminants were adsorbed via multiple adsorbent-adsorbate interactions, including anion exchange, electrostatic interaction, hydrogen bonding and π-π conjugation. Then, a quantitative structure-activity relationship (QSAR) model was constructed by integrating the number of hydrogen bond acceptors, polarity surface area, number of aromatic rings, and Fukui index f(-)x together to reflect the affinity of each contaminant to the adsorbent. Guided by the QSAR model, the negatively charged polystyrene nanoplastics with continuously conjugated aromatic rings were predicted to be effectively adsorbed on LDO@biochar. Experimental tests confirmed a great capacity of LDO@biochar towards the polystyrene nanoplastics, given the equilibrium adsorption capacity as high as 360 mg g-1 at 30-50 °C. This work not only opened up a new avenue for sustainable utilization of sewage sludge towards high-performance environmental functional materials, but also demonstrated the potential of the QSAR analysis as a rapid and accurate approach for guiding the application of an adsorbent to new emerging containments.

Abstract
Objective: To investigate the risk factors of acute Stanford type B aortic dissection (TBAD) complicated with pleural effusion (PE) and the short-term and long-term outcomes of thoracic endovascular aortic repair (TEVAR). Methods: A case-control study. The clinical and imaging data of 1 083 patients with acute TBAD admitted to the General Hospital of Northern Theater Command from April 2002 to December 2020 were retrospectively analyzed, including 211 cases with pleural effusion and 872 cases without pleural effusion. The baseline analysis of the two groups of patients was performed. The risk factors associated with pleural effusion were analyzed by binary logistic regression, and the results were expressed as odds ratio (OR) and 95% confidence interval (CI). According to the quantity of pleural effusion, they were simultaneously divided into small pleural effusion group and medium large pleural effusion group, to compare the short-term and long-term effects of TEVAR patients with different amounts of pleural effusion. Results: The incidence of pericardial effusion (17.5% vs. 3.8%, P<0.001), anemia (21.3% vs. 12.5%, P=0.001), aortic spiral tear (49.8% vs. 37.8%, P=0.002), dissection tear over diaphragm (57.8% vs. 48.1%, P=0.011), serum creatinine [85 (69, 111) vs. 81 (67, 100) μmol/L, P=0.011] and white blood cell levels[(11.3±4.2)×109/L vs. (10.3±4.2)×109/L, P=0.002] in acute TBAD pleural effusion group were significantly higher than those in non-pleural effusion group, and the hemoglobin level was significantly lower than that in non-pleural effusion group [(128±20) vs. (133±17) g/L, P<0.05]. Logistic stepwise regression analysis showed that pericardial effusion (OR=5.038,95%CI 2.962-8.568,P<0.001), anemia (OR=2.047,95%CI 1.361-3.079,P=0.001), spiral tear (OR=1.551,95%CI 1.030-2.336, P=0.002) and elevated white blood cell (OR=1.059,95%CI 1.011-1.102, P=0.005) were independent risk factors for TBAD complicated with pleural effusion. The incidences of all-cause death (4/19 vs. 1.5% vs. 0.9%, P<0.001), aortogenic death (4/19 vs. 0.7% vs. 0.7%, P<0.001) and aortic related adverse events (4/19 vs. 1.5% vs. 1.1%, P<0.001) in patients with large pleural effusion during TEVAR operation were significantly higher than those in patients with small pleural effusion and those without pleural effusion, and the differences were statistically significant. At 1 month follow-up after TEVAR, the incidence of all-cause death (4/16 vs. 3.3% vs. 1.6%, P<0.001), aortogenic death (4/16 vs. 0.8% vs.0.7%, P<0.001), aorta related adverse events (4/16 vs. 4.1% vs. 4.7%, P=0.013) and overall clinical adverse events (4/16 vs.9.8% vs. 6.7%, P=0.014) in the medium and large thoracic group were significantly higher than those in the small pleural effusion group and no pleural effusion group, and the differences were statistically significant. At 1 year follow-up after TEVAR, the incidence of all-cause death (4/15 vs. 4.9% vs. 3.9%, P=0.004), aortogenic death (4/15 vs.2.5% vs. 2.1%, P<0.001), aorta related adverse events (5/15 vs. 11.5% vs. 9.4%, P=0.012) and overall clinical adverse events (5/15 vs. 18.9% vs. 13.1%, P=0.029) in the medium and large thoracic group were significantly higher than those in the small pleural effusion group and no pleural effusion group, and the differences were statistically significant. Conclusions: Single center data showed that pericardial effusion, anemia, spiral tear and elevated white blood cell were independent risk factors for acute TBAD complicated with pleural effusion; the early (1 month) and long-term (1 year) rates of all-cause death, aortic mortality, aortic adverse events and overall clinical adverse events were significantly higher in TBAD patients with moderate pleural effusion after TEVAR, and moderate and large pleural effusion was an independent risk factor for near and long-term aortic related adverse events after TEVAR surgery.

Abstract
In recent years, the incidence of chest malignant tumors in China has increased year by year, which has seriously threatened the health problems of people. Among them, early screening and intervention of patients with chest malignancies is the key to cancer prevention. Early detection, early diagnosis, and early treatment as the "three early prevention" of clinical practice are conducive to improve the survival rate of tumor patients. As a non-invasive and real-time reflection of tumor status, liquid biopsy has gradually received attention in clinical diagnosis and treatment. Circulating tumor cells (CTCs), circulating tumor DNA (ctDNA) and exosomes as liquid biopsy "Three carriages" are not only widely used in the diagnosis, monitoring and prognostic evaluation of chest malignancies, but also face many unknown challenges. In this article, the application of liquid biopsy in chest malignancies in recent years is elaborated in detail, which provides a reference for the formulation of clinical tumor prevention and diagnosis and treatment strategies.

Abstract
Human cytomegalovirus (HCMV) is a leading cause of congenital birth defects. Though the underlying mechanisms remain poorly characterized, mouse models of congenital CMV infection have demonstrated that the neuronal migration process is damaged. In this study, we evaluated the effects of HCMV infection on connexin 43 (Cx43), a crucial adhesion molecule mediating neuronal migration. We show in multiple cellular models that HCMV infection downregulated Cx43 posttranslationally. Further analysis identified the immediate early protein IE1 as the viral protein responsible for the reduction of Cx43. IE1 was found to bind the Cx43 C terminus and promote Cx43 degradation through the ubiquitin-proteasome pathway. Deletion of the Cx43-binding site in IE1 rendered it incapable of inducing Cx43 degradation. We validated the IE1-induced loss of Cx43 in vivo by introducing IE1 into the fetal mouse brain. Noteworthily, ectopic IE1 expression induced cortical atrophy and neuronal migration defects. Several lines of evidence suggest that these damages result from decreased Cx43, and restoration of Cx43 levels partially rescued IE1-induced interruption of neuronal migration. Taken together, the results of our investigation reveal a novel mechanism of HCMV-induced neural maldevelopment and identify a potential intervention target. IMPORTANCE Congenital CMV (cCMV) infection causes neurological sequelae in newborns. Recent studies of cCMV pathogenesis in animal models reveal ventriculomegaly and cortical atrophy associated with impaired neural progenitor cell (NPC) proliferation and migration. In this study, we investigated the mechanisms underlying these NPC abnormalities. We show that Cx43, a critical adhesion molecule mediating NPC migration, is downregulated by HCMV infection in vitro and HCMV-IE1 in vivo. We provide evidence that IE1 interacts with the C terminus of Cx43 to promote its ubiquitination and consequent degradation through the proteasome. Moreover, we demonstrate that introducing IE1 into mouse fetal brains led to neuronal migration defects, which was associated with Cx43 reduction. Deletion of the Cx43-binding region in IE1 or ectopic expression of Cx43 rescued the IE1-induced migration defects in vivo. Our study provides insight into how cCMV infection impairs neuronal migration and reveals a target for therapeutic interventions.

Bulk Bi0.5Sr0.5Fe0.5Cr0.5O3 (BSFCO) is a new compound comprising the R3c structure. The structural, magnetic property and exchange bias (EB) details are investigated. The material was in the super-paramagnetic (SP) state at room temperature. Exchange bias usually occurs at the boundary between different magnetic states after field cooling (HFC) acts on the sample. Here the result shows that changing HFC from 1 to 6 T reduces the HEB value by 16% at 2 K at the same time. Meanwhile, HEB diminishes as the ferromagnetic layer thickness increases. The variation of (the thickness of ferromagnetic layer) tFM with the change of HFC leads to the tuning of HEB by HFC in BSFCO bulk. These effects are obviously different from the phenomenon seen in other oxide types.

Abstract
The presence of human cytomegalovirus (HCMV) in glioblastoma (GBM) and improved outcomes of GBM patients receiving therapies targeting the virus have implicated HCMV in GBM progression. However, a unifying mechanism that accounts for the contribution of HCMV to the malignant phenotype of GBM remains incompletely defined. Here we have identified SOX2, a marker of glioma stem cells (GSCs), as a key determinant of HCMV gene expression in gliomas. Our studies demonstrated that SOX2 downregulated promyelocytic leukemia (PML) and Sp100 and consequently facilitated viral gene expression by decreasing the amount of PML nuclear bodies in HCMV-infected glioma cells. Conversely, the expression of PML antagonized the effects of SOX2 on HCMV gene expression. Furthermore, this regulation of SOX2 on HCMV infection was demonstrated in a neurosphere assay of GSCs and in a murine xenograft model utilizing xenografts from patient-derived glioma tissue. In both cases, SOX2 overexpression facilitated the growth of neurospheres and xenografts implanted in immunodeficient mice. Lastly, the expression of SOX2 and HCMV immediate early 1 (IE1) protein could be correlated in tissues from glioma patients, and interestingly, elevated levels of SOX2 and IE1 were predictive of a worse clinical outcome. These studies argue that HCMV gene expression in gliomas is regulated by SOX2 through its regulation of PML expression and that targeting molecules in this SOX2-PML pathway could identify therapies for glioma treatment.

Abstract
Objective: To investigate the influence of blood pressure control after discharge on prognosis of patients with acute aortic syndrome (AAS) complicated with hypertension who underwent thoracic endovascular aortic repair (TEVAR). Methods: This is a retrospective case analysis. Patients diagnosed with AAS complicated with hypertension and undergoing TEVAR in Northern Theater Command General Hospital from June 2002 to December 2021 were consecutively enrolled. Average systolic blood pressure (SBP) and the occurrence of endpoint events were recorded at one month, one year and every 2 years after TEVAR. According to the patients' average SBP, patients with average SBP<140 mmHg (1 mmHg=0.133 kPa) or<150 mmHg were divided into the target blood pressure achievement group, and the others were divided into target blood pressure non-achievement group. Endpoint events included all-cause death, aortic death, stroke, renal insufficiency, aortic related adverse events and a composite of these events (overall clinical adverse events), and re-accepting TEVAR. The incidence of endpoint events was compared between the two groups at each follow-up period. Results: A total of 987 patients were included, aged (55.7±11.7) years, including 779 male (78.9%). When the cutoff value was 140 mmHg, the rate of average target SBP achievement was 71.2% (703/987) at one month, 66.7% (618/927) during 1st to 12th month and 65.1% (542/832) from the first year to the third year after TEVAR. The proportion of patients taking≥2 antihypertensive agents was higher in the group of target blood pressure non-achievement group than the target blood pressure achievement group after TEVAR at 1 month (74.3% (211/284) vs.65.9% (463/703), P=0.010) and during 1st to 12th month (71.5% (221/309) vs. 63.6% (393/618), P=0.016). There were no statistical differences in the all-cause deaths, stroke, aortic related adverse events, and repeat TEVAR between the two groups (All P>0.05) during above follow-up periods. When the cutoff value was 150 mmHg, the rate of target SBP achievement was 89.3% (881/987) at one month, 85.2% (790/927) during 1st to 12th month and 85.6%(712/832) from the first year to the third year after TEVAR. The incidence of clinical total adverse events (8.8% (12/137) vs. 4.2% (33/790), P=0.021) and repeat TEVAR (4.4% (6/137) vs. 1.0% (8/790), P=0.003) in target blood pressure non-achievement group were significantly higher than the target blood pressure achievement group during 1st to 12th month after TEVAR. The incidence of all-cause deaths (5.8% (7/120) vs. 2.4% (17/712), P=0.037) in the target blood pressure non-achievement group was significantly higher than the target blood pressure achievement group from the first year to the third year follow-up period, but there were no statistical differences in the incidence of clinical total adverse events between the two group (P>0.05). Conclusion: Among TEVAR treated AAS patients complicated with hypertension, the average SBP more than 150 mmHg post discharge is associated with increased risk of adverse events. Ideal blood pressure control should be encouraged to improve the outcome of these patients.

Abstract
Objective: To investigate the different types of renal artery involvement in Stanford type B aortic dissection (TBAD) and the comparison of clinical effecacy after thoracic endovascular aortic repair (TEVAR). Methods: This is a retrospective cohort study included 330 patients with TBAD and renal artery involvement treated with TEVAR from June 2002 to September 2021 in General Hospital of Northern Theater Command of the PLA. According to aortic CTA image, unilateral renal artery involvement conditions were divided into 5 types: the true lumen type (renal artery opening completely from the true lumen), false lumen type (renal artery opening completely from the false lumen), double lumen type (renal artery opening from the true and false double lumen), compression type (renal artery opening connected with the true lumen, but the renal artery opening was extremely squeezed by the inner membrane), open type (renal artery opening with intimal tear). There were seven types of bilateral renal artery involvement: true-true type (true lumen-true lumen type), true and false type (true lumen-false lumen type), true-double type (true lumen-double lumen type), true-opening type (true lumen-opening type), false-false type (false lumen-false lumen type), false-compression type (false lumen-compression type), double-double type (double lumen-double lumen type). The primary observation index of this study was the comparison of postoperative renal function and the incidence of clinical adverse events of different types of renal artery involvement. One-way ANOVA test, Kruskal-Wallis H test and paired sample rank sum test were used to compare postoperative renal function between different types of bilateral renal artery involvement. The Chi-square test or Fisher's exact probability test were used to compare the near and long term adverse events between different types of bilateral renal artery involvement. Kaplan-Meier method was used to compare the all-cause mortality of patients with severe renal functional injury and non-severe renal functional injury before surgery. Results: The average age of the patients included in this study was (53±11) years, including 276 males (83.6%) and 54 females (16.4%). There were statistical difference in the level of serum creatinine (preoperative:H=18.686, P=0.005, postoperative:H=18.101, P=0.006) and cystatin C (preoperative:H=17.566, P=0.007, postoperative:H=10.433, P=0.016), pre-and post-operative, between the seven groups of TBAD patients with different renal artery involvement types (P<0.05), and the false-false type group shown the worst kidney function. However, no statistically significant differences were shown when comparing their pre- and post-operative change values (P>0.05). The 30-day follow-up result showed that there were statistically significant differences in the incidence of postoperative acute kidney injury (χ2=15.623, P=0.007), aorta-related adverse events (χ2=15.523, P=0.010), and intraoperative endoleak (χ2=17.935, P=0.004) among the seven groups, and the false-false group was the highest (2/9, 5/9 and 5/9, respectively). In terms of long-term follow-up results, there were statistically significant differences in all-cause death (χ2=14.772, P=0.011) and non-aortic death (χ2=15.589,P=0.008) among the seven groups. Kaplan-Meier survival analysis showed that patients with worse pre-operative renal function showed higher long-term all cause death (17.7% vs. 4.8%, P=0.009). Conclusions: For TBAD patients with renal artery involvement, there were differences in renal function among different types, and TEVAR showed no significant effect on renal function in TBAD patients. The long-term all cause death was higher in patients with worse renal function pre-operative.

Abstract
Objective: To explore the clinical characteristics and prognostic factors of female patients with Stanford type B aortic dissection. Methods: This is a single-centre retrospective study. Consecutive patients diagnosed with Stanford type B aortic dissection in General Hospital of Northern Theater Command from June 2002 to August 2021 were enrolled, and grouped based on sex. According to the general clinical conditions and complications of aortic dissection tear, patients were treated with thoracic endovascular aortic repair, surgery, or optimal medication. The clinical characteristics and aortic imaging data of the patients at different stages were collected, adverse events including all-cause deaths, stroke, and occurrence of aortic-related adverse events were obtained during hospitalization and within 30 days and at 1 and 5 years after discharge. According to the time of death, death was classified as in-hospital death, out-of-hospital death, and in-hospital death was divided into preoperative death, intraoperative death and postoperative death. According to the cause of death, death was classified as aortic death, cardiac death and other causes of death. Aortic-related adverse events within 30 days after discharge included new paraplegia, post-luminal repair syndrome, and aortic death; long-term (≥1 year after discharge) aortic-related adverse events included aortic death, recurrent aortic dissection, endoleak and distal ulcer events. The clinical characteristics, short-term and long-term prognosis was compared between the groups. Logistic regression analysis was used to explore the association between different clinical factors and all-cause mortality within 30 days in female and male groups separately. Results: A total of 1 094 patients with Stanford type B aortic dissection were enrolled, mean age was (53.9±12.1) years, and 861 (78.7%) were male and 233 (21.3%) were female. (1) Clinical characteristics: compared with male patients, female patients were featured with older average age, higher proportion of aged≥60 years old, back pain, anemia, optimal medication treatment, and higher cholesterol level; while lower proportion of smoking and drinking history, body mass index, calcium antagonists use, creatine kinase level, and white blood cell count (all P<0.05). However, there was no significant difference in dissection tear and clinical stage, history of coronary heart disease, diabetes, hypertension, and cerebrovascular disease between female and male patients (all P>0.05). (2) Follow-up result: compared with male patients, female patients had a higher rate of 30-day death [6.9% (16/233) vs. 3.8% (33/861), P=0.047], in-hospital death (5.6% (13/233) vs. 2.7% (23/861), P=0.027), preoperative death (3.9% (9/233) vs. 1.5% (12/861), P=0.023) and aorta death (6.0% (14/233) vs. 3.1% (27/861), P=0.041). The 1-year and 5-year follow-up results demonstrated that there were no significant differences in death, cerebrovascular disease, and aorta-related adverse events between the two groups (all P>0.05). (3) Prognostic factors: the results of the univariate logistic regression analysis showed that body mass index>24 kg/m2 (HR=1.087, 95%CI 1.029-1.149, P=0.013), history of anemia (HR=2.987, 95%CI 1.054-8.468, P=0.032), hypertension (HR=1.094, 95%CI 1.047-1.143, P=0.040) and troponin-T>0.05 μg/L (HR=5.818, 95%CI 1.611-21.018, P=0.003)were associated with an increased risk of all-cause mortality within 30 days in female patients. Conclusions: Female patients with Stanford type B aortic dissection have specific clinical characteristics, such as older age at presentation, higher rates of anemia and combined back pain, and higher total cholesterol levels. The risk of death within 1 month is higher in female patients than in male patients, which may be associated with body mass index, hypertension, anemia and troponin-T, but the long-term prognosis for both female and male patients is comparable.

Abstract
During the long coevolution of human cytomegalovirus (HCMV) and humans, the host has formed a defense system of multiple layers to eradicate the invader, and the virus has developed various strategies to evade host surveillance programs. The intrinsic immunity primarily orchestrated by promyelocytic leukemia (PML) nuclear bodies (PML-NBs) represents the first line of defense against HCMV infection. Here, we demonstrate that microrchidia family CW-type zinc finger 3 (MORC3), a PML-NBs component, is a restriction factor targeting HCMV infection. We show that depletion of MORC3 through knockdown by RNA interference or knockout by CRISPR-Cas9 augmented immediate-early protein 1 (IE1) gene expression and subsequent viral replication, and overexpressing MORC3 inhibited HCMV replication by suppressing IE1 gene expression. To relief the restriction, HCMV induces transient reduction of MORC3 protein level via the ubiquitin-proteasome pathway during the immediate-early to early stage. However, MORC3 transcription is upregulated, and the protein level recovers in the late stages. Further analyses with temporal-controlled MORC3 expression and the major immediate-early promoter (MIEP)-based reporters show that MORC3 suppresses MIEP activity and consequent IE1 expression with the assistance of PML. Taken together, our data reveal that HCMV enforces temporary loss of MORC3 to evade its repression against the initiation of immediate-early gene expression.

Abstract
Objective: To investigate the clinical characteristics and diagnosis and treatment strategies of patients with severe traumatic aortic injury (TAI). Methods: A total of 25 patients with TAI, who hospitalized in our hospital between August 2005 to March 2021 and underwent thoracic aortic endovascular repair (TEVAR), were included in this retrospective study. According to the time from admission to TEVAR, the patients were divided into emergency TEVAR group (14 cases, TEVAR within 24 h of admission) and elective TEVAR group (11 cases, patients underwent surgery or fracture reduction and fixation first for serious injuries and then underwent TEVAR more than 24 h after admission). The general clinical data of patients, injury severity score (ISS), time from admission to intervention, total hospital stay, the proportion of closed chest drainage and the proportion of abdominal organ repair were obtained and compared. Clinical follow-up and 1-year postoperative aortic computed tomography angiography (CTA) were performed on the patients. Death, the occurrence of aortic adverse events and injury recovery were followed up and recorded. Results: The mean age of these 25 TAI patients was (41.4±14.4) years, 20 patients were males (80.0%). 21 patients (84.0%) had persistent chest and back pain, 17 (68.0%) had pleural effusion and 5 (20.0%) had mediastinal hematoma. The injury severity score (ISS) was significantly higher in the elective TEVAR group than in the emergency TEVAR group (24.9±14.4 vs. 35.5±9.3, P=0.044). The time from admission to intervention ((1.0±0.0) d vs. (3.4±0.9) d, P<0.001], the time from admission to TEVAR ((1.0±0.0) d vs. (11.5±13.8) d, P=0.030) and total hospital stay ((6.1±2.3) d vs. (26.8±7.7) d, P<0.001) were significantly longer in elective TEVAR group than in emergency TEVAR group. The proportion of thoracic closed drainage was significantly lower in the elective TEVAR group than in the emergency TEVAR group (9 (64.3%) vs. 2 (18.2%), P=0.042). The proportion of abdominal organ repair was significantly higher than in the emergency TEVAR group (0 vs. 4 (36.4%), P=0.026). All of 25 patients were discharged alive and followed up for (84.0±30.5) months. All patients survived and completed 1-year postoperation CTA. There were no aortic adverse events occurred, and no complications after surgery, and the fractures and organ injuries healed well. Conclusions: The clinical characteristics of severe TAI are acute multi-injuries combined with persistent chest and/or back pain, pleural effusion, and mediastinal hematoma. Timely diagnosis and treatment are important factors for the outcome. The treatment strategy for multi-injuries should give priority to dealing with life-threatening injuries. TEVAR is the primary treatment strategy for severe TAI and is related to satisfactory outcomes.

Abstract
Objective: To investigate the clinicopathological features of early gastric cancers after Helicobacter pylori (H. pylori) eradication. Methods: The clinical data of 26 cases of gastric cancer that were diagnosed after H. pylori eradication and 45 cases without H. pylori eradication in the 989 Hospital of the Joint Logistics Support Force of the People's Liberation Army (the former 152 Hospital), Pingdingshan, China from 2013 to 2021 were collected. The histological, immunophenotypic and clinical characteristics of the two groups were compared, and discussed with review of the related literature. Results: Among the gastric cancer patients with H. pylori eradication, there were 20 males and 6 females with a median age of 65 years (range 53 to 77 years). The cancer involved the upper part of the stomach in 12 cases, the middle part of the stomach in 4 cases, and the lower part of the stomach in 10 cases. The median diameter of the tumors was 12 mm (range 4-29 mm). According to the Paris Classification, 4 cases were 0-Ⅱa, 4 cases were 0-Ⅱb, 18 cases were 0-Ⅱc. White light endoscopy showed that the lesions were reddish to yellowish. The lesion boundary was clear in 12 cases and was unclear or gastritis-like changes in 14 cases, while the irregular microvascular structure and microsurface structure, as well as the relatively visible spinous boundary, were visible under narrow-band imaging. There were 20 cases of well-differentiated tubular adenocarcinoma, 4 cases of highly to moderately differentiated tubular adenocarcinoma, and 2 cases of well-differentiated tubular adenocarcinoma with papillary adenocarcinoma. Compared with gastric cancers without H. pylori eradication, gastric cancers diagnosed after H. pylori eradication was associated with lower nucleus-cytoplasm ratio (<50%), normal epithelial coverage on the cancer surface, mild atypical epithelial coverage on the cancer surface, elongation of non-cancerous glands in the cancer tissue and subepithelial progression of cancerous glands were higher (P<0.05). The cellular immunophenotypes were gastric type in 6 cases, intestinal type in 4 cases and gastrointestinal mixed type in 16 cases. Conclusions: The early gastric cancers diagnosed after H. pylori eradication are more subtle clinically and mostly well-differentiated tubular adenocarcinoma. The important morphological features of gastric cancer diagnosed after H. pylori eradication are decreased cytological atypia and overlying normal epithelium or mildly atypical epithelium of the cancer. Understanding and recognizing these morphological features are helpful to make correct endoscopic and pathological diagnoses.

Abstract
The tetanus has been eliminated in the pregnancy women and newborns in China. However, there is a gap for adult tetanus immunization, and the risk of tetanus infection cannot be ignored. In order to clearly understand the effect of the tetanus to human beings and the current use of tetanus immunological preparation for adult post-exposure prophylaxis, the incidence of the tetanus, the use status of tetanus immunological preparation and recommendations for post-exposure prophylaxis at home and abroad were reviewed and summarized, which may provide academic evidence for post-exposure prophylaxis procedures and use of tetanus immunological preparation.

Abstract
Objective: To investigate the clinicopathological features of very well-differentiated adenocarcinoma (VWDA) of the stomach. Methods: The clinicopathological data of 12 cases of VWDA of the stomach were collected retrospectively at the People's Liberation Army Joint Logistics Support Force 989 Hospital (formerly 152 Hospital), Pingdingshan, China, from January 2013 to May 2021. The histological characteristics and immunophenotypes were observed and analyzed with review of current literature. Results: There were 8 males and 4 females with a median age of 63 years (range 47 to 80 years). The tumor involved in the upper part of the stomach in 6 cases, the middle part in 2 cases, and the lower part in 4 cases. The median diameter of the tumors was 17 mm (range 5-65 mm). The tumor cells were similar to absorbent cells, Paneth cells, foveolar epithelial cells, and goblet cells. The cells were arranged in a single layer, and the nuclei were slightly enlarged and located at the base. The nuclei were fusiform to slightly irregular, with loss of nuclear polarity. Early tubular VWDA was found in 9 cases, and the tumor glands were similar to intestinal metaplasia. In two cases the tumors infiltrated into the submucosa. The lesions in the mucosa and submucosa showed the glands with cystic expansion, bending, branching, spiky and abortive growth pattern. One case of early papillary tubular VWDA was confined to the mucosal layer and composed of foveolar-type epithelial cells. There were two cases of advanced papillary tubular VWDA, which consisted of foveolar-type epithelial, pyloric glands, or mucinous neck cells and were associated with intra-lymphatic cancer embolus and lymph node metastases. Background mucosal atrophy and intestinal metaplasia were observed in all cases. Immunohistochemical staining showed intestinal type VWDA in 1 case, mixed gastrointestinal type VWDA in 9 cases, and gastric type VWDA in 2 cases. The Ki-67 proliferation index of 8 cases limited to the mucosa was 40%-70%, 2 cases of infiltration into the submucosa and 2 cases of advanced carcinoma was 10%-25%. All the tumors showed a wild type of p53 protein expression pattern and negative HER2. Adenocarcinoma or high-grade dysplasia was diagnosed on preoperative biopsy in 5 cases, and chronic atrophic gastritis with intestinal metaplasia in 7 cases. The median follow-up time was 28 months (range 12-72 months). No recurrence was found in the 10 patients with early cancer. Of the two patients with advanced carcinoma, one patient had lung metastases and the other died. Conclusions: Gastric VWDA is a rare low-grade malignancy with structural features of highly differentiated adenocarcinoma and extremely low cytological atypia. The diagnostic value of structural abnormality is significantly greater than cytological atypia. The invasive growth of irregular glands in the deep mucosa and submucosa is reliable evidence for diagnosis. The diagnosis of intramucosal VWDA is challenging and very difficult in some biopsy specimens.

Abstract
Congenital cytomegalovirus (cCMV) infection is the leading infectious cause of neurodevelopmental disorders. However, the neuropathogenesis remains largely elusive due to a lack of informative animal models. In this study, we developed a congenital murine CMV (cMCMV) infection mouse model with high survival rate and long survival period that allowed long-term follow-up study of neurodevelopmental disorders. This model involves in utero intracranial injection and mimics many reported clinical manifestations of cCMV infection in infants, including growth restriction, hearing loss, and impaired cognitive and learning-memory abilities. We observed that abnormalities in MRI/CT neuroimaging were consistent with brain hemorrhage and loss of brain parenchyma, which was confirmed by pathological analysis. Neuropathological findings included ventriculomegaly and cortical atrophy associated with impaired proliferation and migration of neural progenitor cells in the developing brain at both embryonic and postnatal stages. Robust inflammatory responses during infection were shown by elevated inflammatory cytokine levels, leukocyte infiltration, and activation of microglia and astrocytes in the brain. Pathological analyses and CT neuroimaging revealed brain calcifications induced by cMCMV infection and cell death via pyroptosis. Furthermore, antiviral treatment with ganciclovir significantly improved neurological functions and mitigated brain damage as shown by CT neuroimaging. These results demonstrate that this model is suitable for investigation of mechanisms of infection-induced brain damage and long-term studies of neurodevelopmental disorders, including the development of interventions to limit CNS damage associated with cCMV infection.

Abstract
BACKGROUND Tumor mutational burden (TMB) measurements aid in identifying patients who are likely to benefit from immunotherapy; however, there is empirical variability across panel assays and factors contributing to this variability have not been comprehensively investigated. Identifying sources of variability can help facilitate comparability across different panel assays, which may aid in broader adoption of panel assays and development of clinical applications. MATERIALS AND METHODS Twenty-nine tumor samples and 10 human-derived cell lines were processed and distributed to 16 laboratories; each used their own bioinformatics pipelines to calculate TMB and compare to whole exome results. Additionally, theoretical positive percent agreement (PPA) and negative percent agreement (NPA) of TMB were estimated. The impact of filtering pathogenic and germline variants on TMB estimates was assessed. Calibration curves specific to each panel assay were developed to facilitate translation of panel TMB values to whole exome sequencing (WES) TMB values. RESULTS Panel sizes >667 Kb are necessary to maintain adequate PPA and NPA for calling TMB high versus TMB low across the range of cut-offs used in practice. Failure to filter out pathogenic variants when estimating panel TMB resulted in overestimating TMB relative to WES for all assays. Filtering out potential germline variants at >0% population minor allele frequency resulted in the strongest correlation to WES TMB. Application of a calibration approach derived from The Cancer Genome Atlas data, tailored to each panel assay, reduced the spread of panel TMB values around the WES TMB as reflected in lower root mean squared error (RMSE) for 26/29 (90%) of the clinical samples. CONCLUSIONS Estimation of TMB varies across different panels, with panel size, gene content, and bioinformatics pipelines contributing to empirical variability. Statistical calibration can achieve more consistent results across panels and allows for comparison of TMB values across various panel assays. To promote reproducibility and comparability across assays, a software tool was developed and made publicly available.

Abstract
Objective: To study the real-world outcome of China FDA-approved Sofosbuvir (SOF)/Velpatasvir (VEL) in Northwest China. Methods: In this multicenter, prospective, real-world cohort study, we recruited patients from 10 sites from Northwest China, who were chronically infected with HCV GTs 1-6 from 06/2018 to 09/2019. Patients received SOF (400mg)/VEL (100mg) for 12 weeks, and with ribavirin 900-1200 mg for GT3 cirrhosis and for any genotype decompensated cirrhosis. The primary endpoint was sustained virological response at 12-weeks post-treatment (SVR12) and safety. The secondary endpoint was the change of liver function after the achievement of SVR12. Results: Totally, 143 patients were enrolled in the study, four patients were lost to follow-up and one died during the follow-up, 138 patients were included in per-protocol analysis. Of the 138 patients, the mean age 53 years, 53.6% male, 94.2% Han nationality, 53.6% liver cirrhosis, 10.1% HBsAg(+), 6.5% renal dysfunction, 5.1% treatment-experienced, and 16.7% patients received ribavirin treatment. The genotype distribution was as follows: 35.5% GT1, 42.8% GT2, 15.9% GT3, and 5.8% un-typed. The SVR12 rate was 96.5% (138/143, 95%CI: 93.5%-99.6%) for intention-to-treat analysis, and in per-protocol analysis, all 138 patients obtained SVR12 (100%). Compared with baseline, the serum total bilirubin, ALT and AFP levels decreased (all P < 0.05), as well as increased ALB and platelet count (all P < 0.001) at post-treatment 12-weeks. Overall adverse events (AEs) rate is 29.0%, and the most common AEs were anemia (14.5%) and fatigue (8.0%). Severe side effects (edema and fatigue) occurred in 2 patients, one of whom needed a short-term interruption of treatment due to fatigue. Conclusion: In this real-world cohort study, 12-week SOF/VEL regimen with or without ribavirin achieved high SVR12 rates (96.5%-100% overall) with excellent safety profile among patients with HCV GT1/2/3 infection including patients with GT3 and cirrhosis, and led to improvement of liver function.

Abstract
Objective: To explore the effect of systolic blood pressure (SBP) trajectories on cancers. Methods: The relevant data of 54, 888 employees of Kailuan (Group) Limited Liability Company who participated in the 3 health examinations from 2006-2007, 2008-2009, 2010-2011 were collected and the new onset cancer cases were recorded. The systolic blood pressure trajectory grouping was carried out using the blood pressure measurement values of the 3 physical examinations. The life table method was used to calculate the incidence of cancer, and the multivariate Cox proportional hazard regression model was used to analyze the influence factors of cancer. Results: According to the systolic blood pressure trajectory, 54, 888 subjects were divided into 5 groups, including 14, 326 in the low-stable group, 25, 630 in the moderate-stable group, 5, 390 in the moderate-increasing group, 6, 438 in the elevated-lowering group, and 3, 104 in the elevated-stable group. A total of 1, 070 new onset cancer occurred during the follow-up period of (4.95±0.53) years. The incidence of cancer in the low-stable group, moderate-stable group, moderate-increasing group, elevated-lowering group and elevated-stable group were 1.3% (177/14, 326), 2.2% (491/25, 360), 3.1% (147/5, 390), 2.7% (156/6, 438) and 3.8% (99/3, 104), respectively, the difference was statistically significant (P<0.001). After adjusting for gender, age, smoking, drinking, physical exercise, body mass index (BMI), fasting blood glucose, total cholesterol, antihypertensive drugs, hypoglycemic drugs, and lipid-lowering drugs, multivariate Cox regression analysis showed that the systolic blood pressure trajectory was related to the incidence of cancer. Compared with the low-stable group, the Hazard ratio (HR) in the moderate-stable group, moderate-increasing group, elevated-lowering group and elevated-stable group were 1.413, 1.731, 1.557 and 1.907, respectively (all P<0.001). Conclusion: High systolic blood pressure trajectories is the risk factor for cancer.

Abstract
Objective: To evaluate the five-year safety and efficacy of the second generation biodegradable polymer sirolimus-eluting stent (EXCROSSAL) in treating patients with de novo coronary artery diseases. Methods: Patients with coronary artery disease (CAD)who were implanted with EXTROSSAL stents in CREDIT Ⅱ and CREDIT Ⅲ study were included. CREDIT Ⅱ was a randomized trial, and CREDIT Ⅲ was a single-arm study. From November 2013 to December 2014, 833 CAD patients with de novo coronary lesions implanted with EXTROSSAL stents were selected from 33 centers in China. The primary outcome was 5-year target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction and clinically indicated target lesion revascularization. Secondary endpoints was patient-oriented composite endpoint (PoCE), including all-cause death, all myocardial infarction, or any revascularization within 5 years post stenting and stent thrombosis according to Academic Research Consortium's (ARC) definition. Kaplan Meier method was used to calculate the incidence of TLF and PoCE within 5 years after operation. Univariate Cox regression analysis was used to analyze the impacts of diabetes, small vessel disease (vessel diameter ≤ 2.74 mm), lesion length ≥ 16.7 mm and multivessel disease on the incidence of TLF within 5 years after operation. Results: A total of 833 patients were included in this study including 579 males (69.5%), the age was (59.3±9.1) years. And 832 (99.9%) patients completed 5-year clinical follow-up. The incidence of TLF and PoCE in the 5-year follow-up were 10.6%(86/811) and 15.5%(126/811), respectively. Stent thrombosis occurred in 1.0%(8/811) of patients. Univariate Cox regression analysis showed that vessel diameter ≤ 2.74 mm (HR=3.20,95%CI 1.90-5.39,P<0.001), lesion length ≥ 16.7 mm (HR=1.88,95%CI 1.18-2.99,P=0.007) and multivessel disease (HR=2.44,95%CI 1.60-3.72,P<0.001) were related factors of TLF within 5 years after operation. Conclusion: EXCROSSAL stent is effective and safe in treating CAD patients with de novo coronary lesions, with low incidence of TLF and PoCE within 5 years after operation.

Abstract
Objective: To compare the application effect of blue dye single tracer and blue dye combined with nuclide double tracer in sentinel lymph node biopsy (SLNB) of breast cancer surgery. Methods: A total of 92 breast cancer patients in Shandong Cancer Hospital and Institute from November 2017 to October 2019 underwent methyleneblue dye combined with (99)Tc(m) sulfur colloid nuclide double tracer in SLNB, while other 92 cases in Jining First People Hospital underwent blue dye single tracer. The number of SLN detection, detection rate, accuracy rate, sensitivity, and false negative rate of the two groups were compared. The impacts of age, menstruation, tumor location, tumor size, clinical stage, pathological type, and estrogen receptor (ER), progesterone receptor (PR), human epidermal receptor 2 (HER-2), molecular typing, dynamic enhanced magnetic resonance imaging (DCE-MRI)on the detection rate of SLN were analyzed. Results: The number of detection, detection rate, accuracy, sensitivity, and false negative rate of the blue dye single tracer group were 3.20±1.10, 90.22%, 93.48%, 95.24% and 4.76%, respectively; the double tracer group were 3.37±1.02, 92.39%, 95.65%, 95.65% and 4.35%, respectively, without significant difference (all P>0.05). In different age, menstrual condition, tumor location, clinical stage, pathological type, ER, PR, HER-2 expression and molecular typing, the detection rate of single tracer group and double tracer group had no significant difference (all P>0.05). However, in the tumor size of 2-5 cm and without DCE-MRI examination, the detection rate of single tracer group was significantly lower than that of double tracer group. Conclusion: The effect of blue dye single tracer in detecting SLN of breast cancer is equivalent to that of double tracer method, which is worthy of promotion and application in primary hospitals.

Abstract
Osteosarcoma is the most prevailing malignant bone tumor among adolescents. Punicalagin, a polyphenolic compound extracted from pomegranate, possesses many functions such as anti-oxidation, anti-bacterial, anti-virus, and immunosuppression, which can counter the aggressiveness of a variety of cancers such cervical, ovarian and prostate. This study aimed to investigate the inhibitory effect of punicalagin on the proliferation and metastasis of osteosarcoma cells and its potential regulatory mechanisms. Osteosarcoma cell lines (HOS cells, U2OS cells and MG63 cells) were treated with different doses of punicalagin, and the effects on osteosarcoma cell activity were examined in vitro using cell counting kit-8 (CCK-8), colony formation and apoptosis assays. The mobility, migration and invasion abilities of osteosarcoma cells were detected by wound healing and Transwell assays. NF-κB activity was explored by the NF-κB p65 luciferase reporter assay. Western blot was used to investigate the expressions of downstream proteins. We found that punicalagin inhibited the viability of osteosarcoma cells in vitro in dose-dependent and time-dependent manners and promoted apoptosis. In addition, punicalagin could significantly impede the mobility, migration and invasion abilities of osteosarcoma cells. In terms of mechanism, punicalagin down-regulated the expressions of p65, survivin, XIAP, CIAP2 and other proteins, and suppressed the proliferation and metastasis of osteosarcoma cells by repressing NF-κB signaling pathway. In conclusion, it is concluded that punicalagin restrains the growth and metastasis of osteosarcoma by obstructing the NF-κB signal transduction pathway.

Abstract
Chronic hepatitis C (CHC) is one of the most important causes of chronic liver disease in the world. Among them, chronic hepatitis C with genotype 3 is closely related to the progression of liver disease, and its treatment is still challenging. With the passage of time, the proportion of patients with chronic hepatitis C genotype 3 has been on the rise in China, which raises the difficulty of treatment. Therefore, we need to combine domestic and foreign research to explore a more suitable plan for Chinese patients with chronic hepatitis C genotype 3.

Abstract
Objective: To investigate the effect of RATEA16 scaffold on the proliferation of human umbilical vein endothelial cells (HUVEC) and the effect of new self-assembling peptide hydrogel (RATEA16) scaffold with vascular endothelial growth factor (VEGF) on promoting angiogenesis. Methods: RATEA16 hydrogel was prepared, then the injectability, microstructure, degradation, biocompatibility of RATEA16 hydrogel were determined. HUVEC were cultured with RATEA16 scaffold to detect cell morphology and proliferation. HUVEC were cultured on RATEA16 scaffold with VEGF for 24 h. The expression of VEGF-A, von Willebrand factor (vWF), matrix metalloproteinase-9 (MMP-9) and platelet endothelial cell adhesion molecule-1 (PECAM-1) were detected by using real-time PCR to evaluate the effects of the scaffold with VEGF system on HUVEC differentiation. Results: The sol-gel transition was completed under neutral condition (pH=7.4) adjusted by Tris-HCl solution. The hydrogel could be easily injected from a syringe. It presented a porous and interconnected internal structure and the porosity of the scaffold was (67.3±9.4)%. After 4 week degradation in vitro, the residual weight was still (82.354±0.006)%, which exhibited slow degradation. HUVEC grew well after being cultured in leach liquor of RATEA16 hydrogel for 24 h, and there was no significant difference in HUVEC cell viability compared with that of the control group (P>0.05). HUVEC encapsulated in RATEA16 hydrogel appeared round in shape and exhibited effectively continuous proliferation. When HUVEC were cultured on RATEA16 hydrogel with VEGF for 24 h, the formation of vascular-like structures was observed. The expression of VEGF-A and MMP-9 was 1.5-2.0 times that of control group, and vWF was 10 times and PECAM-1 was 55 times compared with that of the control group (P<0.05). Conclusions: The RATEA16 hydrogel used in this study could be prepared by simply adjusting pH to neutral. This hydrogel exhibited good biodegradability, slow degradation and injectability. HUVEC might attach and spread in RATEA16 scaffold. The RATEA16 scaffold with VEGF could promote angiogenic differentiation of HUVEC. The novel scaffold is expected to achieve the critical vascularization process in bone tissue regeneration.

Abstract
The contribution of colostrum to passive immunity transfer and intestinal protection is well known; however, the effects of colostrum intake on the expression of antimicrobial peptides (AP) and Fc receptors in the intestine of neonatal calves are unclear. Our aim was to investigate changes in the expression of AP and Fc receptor in the small intestine of calves in the first 36 h postpartum. Twenty-four Holstein bull calves were used in this study, of which 18 calves were administered 3.2 L of pooled colostrum for each calf per meal via an esophageal tube. Calves were slaughtered at 8 h (1 meal at 1-2 h), 24 h (2 meals at 1-2 h and 10-12 h), and 36 h (3 meals at 1-2 h, 10-12 h, and 22-24 h) postpartum. The remaining 6 calves without any milk administration were slaughtered at 2 h postpartum. Samples of blood and jejunum digesta were collected to determine immunoglobulin concentration using ELISA. Samples of the duodenum, jejunum, and ileum tissues after slaughter were collected to determine AP and Fc receptor expression using quantitative real-time PCR. In calves administered colostrum, IgG concentration in jejunum digesta rapidly decreased in an age-dependent manner (33.41, 9.47, and 0.34 mg/mL at 8, 24, and 36 h, respectively), whereas serum IgG concentration increased significantly, from 0.25 μg/mL at 2 h to 21.72 mg/mL at 24 h. Cathelicidin-4, β-defensin (DEFB)-7, and enteric β-defensin expression was upregulated at 8 h postpartum in the duodenum and jejunum compared with that at 2 h, but progressive recovery was detected from 24 h onward. Higher expression of cathelicidin-4, regenerating family member 3γ, lysozyme (LYZ), LYZ1, and LYZ2 and lower expression of DEFB, DEFB1, DEFB7, DEFB10, and enteric β-defensin were observed in the duodenum and jejunum compared with the ileum. Differences in AP expression between intestinal regions suggested that the innate immune defense mechanism varied significantly among the duodenum, jejunum, and ileum. No difference in the expression of Fc fragment of the IgG receptor was observed either among ages or small intestinal regions. The Fcγ receptor (FcγR)Ia and FcγRIIb expression was the highest at 8 h compared with that at 2, 24, and 36 h, and expression of FcγRIa, FcγRIIb, and FcγRIIIa was higher in the duodenum and jejunum than in the ileum. These results indicated that AP and Fcγ receptors might play important roles in intestinal defense during the passive immunity period.

Abstract
Objective: To investigate the expression of IGF1R-Ras and RAGE-HMGB1 signaling pathways in colorectal cancer patients with type 2 diabetes mellitus and their significance. Methods: The resected cancer tissues were obtained from 59 patients with colorectal cancer (CRC), including 29 patients with type 2 diabetes mellitus (CRC/DM group) and 30 with CRC alone (CRC group). The expressions of IGF1R, Ras, RAGE and HMGB1 in cancer tissues were detected by immunohistochemistry. The differences between the two groups were compared and the relationship between the expression and clinicopathological characteristics was analyzed. Results: In CRC/DM group, the positive rates of IGF1R and Ras were both 65.5% (19/29), and 51.7% (15/29) patients had IGF1R+ Ras+ immunophenotype, which were significantly higher than those in CRC group [33.3% (10/30), 36.7% (11/30) and 20.0% (6/30); P=0.013, 0.027 and 0.011, respectively]. The expression of IGF1R and Ras in CRC / DM group was positively correlated (r=0.479, P=0.017). The positive rate of RAGE expression in CRC group and CRC/DM group was 70.0% (21/30) and 72.4% (21/29) respectively, and the positive rate of HMGB1 expression was 46.7% (14/30) and 58.6% (17/29) respectively, neither was observed with significant difference (P=0.358 and 0.838). However, the proportion of patients with RAGE+ HMGB1+ immunophenotype in CRC/DM group [55.2% (16/29)] was higher than that in CRC Group [26.7% (8/30)] which was statistically significant (P=0.026), and the expression of both proteins was positively correlated in CRC/DM group (r=0.578, P=0.003). The clinicopathological analysis showed that in both groups the expression of IGF1R, Ras, RAGE and HMGB1 had no correlation with the sex, age, differentiation degree, tumor length, T stage and lymph node metastasis (P>0.05). Conclusion: Both IGF1R-Ras and RAGE-HMGB1 pathways may be involved in the oncogenesis of colorectal cancer in patients with type 2 diabetes.

Abstract
Objective: To compare the differences in the detection rates of cytomegalovirus (CMV) infection between the left and right colons for guiding endoscopic biopsy-sites. Methods: The cases of colonic CMV infection confirmed by histology at the Peking Union Medical College Hospital from July 2015 to July 2018 were collected and analyzed. Splenic curvature was used as the dividing point between the left and right colons. The CMV inclusions were identified histologically, and the CMV infected cells were detected using immunohistochemistry (EnVision method). The numbers of infected cells in the left and right colons were compared by histological and immunohistochemical results. A total of 731 patients were identified. Ten of the 731 patients had histological specimens of both left and right colons and were confirmed with CMV EnVision immunohistochemical study. There were 25 biopsy or resection specimens. Seven patients were male and 3 were female, and their ages ranged from 29 to 66 years, with a median age of 55 years. All of the 10 patients were also diagnosed with ulcerative colitis. Results: The number of the cells infected with CMV in the left colon was 115 (1-41), while that in the right colon was 76 (0-51). In 8/10 cases, the number of CMV infected cells in the left colon was more than that in the right colon. Conclusions: The study on the biopsies and resection specimens suggests that CMV infection is mostly present in the left colon. The left colon thus might be an important endoscopic biopsy-site for the cases with suspicion of CMV infection.

Abstract
Objective: To evaluate the long-term efficacy of a second generation biodegradable polymer sirolimus-eluting stent (EXCEL2) in treating patients with de novo coronary artery diseases. Methods: CREDIT Ⅱ trial was a prospective, multicenter, randomized, controlled study, conducted at 15 Chinese cardiac centres from November 2013 to December 2014. In this analysis, eligible patients for coronary stenting (n=419) were randomized to receive either the EXCEL2 stent (n=208) or the EXCEL stent (n=211). The primary endpoint was target lesion failure (TLF) at 3 years after PCI defined as a composite endpoints of cardiac death, target vessel myocardial infarction (TVMI), or clinically indicated target lesion revascularization (CI-TLR). Secondary endpoints included patient-oriented composite endpoint (PoCE) including all-cause death, all MI, or any revascularization at 3 years and independent components, and stent thrombosis according to Academic Research Consortium's (ARC) definition. Results: Among 419 enrolled patients, 413 (98.6%) patients completed 3-year clinical follow-up. Compared with the EXCEL group, 3-year TLF (5.4%(11/204) vs. 11.5% (24/209), P=0.025) and PoCE (9.8% (20/204) vs. 20.1% (42/209), P=0.003) were significantly lower in the EXCEL2 group. The cumulative event rate of CI-TLR (2.0% (4/204) vs. 5.7% (12/209), P=0.042) and any revascularization (4.9% (10/204) vs. 14.4% (30/209), P=0.001) were statistically lower in the EXCEL2 group than in the EXCEL group. There were no significant difference between two groups in terms of all-cause death and all MI. Rates of stent thrombosis were low without significant difference between the two groups (EXCEL2 vs. EXCEL, 1.0% (2/204) vs. 2.9% (6/209), P=0.285). Conclusion: 3-year clinical follow-up results demonstrate that EXCEL2 stents are effective and safe in treating CAD patients with de novo coronary lesions.

Abstract
Objective: To analyze the changes of growth and development of normal fetal ventricles and cisterna magna with gestational age(GA) and the correlation with fetal gender in the second and third trimester,and establish the MR prenatal diagnosis reference standards. Methods: A total of 633 fetuses (mean GA (27.0±4.1) weeks (18.9-40.6 weeks))without central nervous system abnormalities were retrospectively collected from the Obstetrics and Gynecology Hospital of Fudan University from June 2012 to August 2017. The lateral ventricle trigonometric width (LVTW), third ventricle width (TVW), fourth ventricle width (FVW), anterior-posterior diameter of the fourth ventricle(APDFV), cavum septum pellucidum width (CSPW) and cisterna magna width (CMW) were obtained in the standard measure planes on MR image.The correlation between the biometrics and GA and the correlation between the biometrics and fetal gender were analyzed respectively, and the normal reference values of the biometrics were calculated. Spearman correlation analysis, Pearson correlation analysis,linear regression analysis, independent samples t-test and paired samples t-test were used for statistic analysis. Results: (1)Fetal LLVTW,RLVTW,TVW,CSPW and CMW in second and third trimesters were correlated with GA at medium and low levels(the correlation coefficient r were 0.311, 0.277, 0.207, 0.226, 0.295, respectively, all P<0.01). FVW and APDFV were statistically correlated with GA, and the linear regression equations were as follows: y=0.022×GA-0.043 (adjusted R(2)=0.642); y=0.018×GA-0.159 (adjusted R(2)=0.690). (2)Fetal LLVTW,RLVTW,FVW,APDFV and CSPW were not correlated with fetal gender in second and third trimesters(r=-0.078,-0.057,-0.087,-0.004 and 0.024, P=0.124,0.258,0.085,0.931 and 0.618, all P>0.05). TVW and CMW were statistically correlated with fetal gender(r=-0.310, -0.180, P=0.000, 0.006, all P<0.05). (3) The mean values of LLVTW and RLVTW were (0.71±0.13) cm and (0.68±0.13) cm, respectively, and significant difference was found between them(t=3.180, P=0.002). The mean value of CSPW was (0.59±0.15) cm. And the mean values of male and female fetuses for TVW and CMW were (0.17±0.05) cm, (0.16±0.06) cm and (0.68±0.15) cm, (0.58±0.15) cm, respectively. The corresponding prenatal MRI diagnostic criteria were as follows: LLVTW 1.1 cm, RLVTW 1.0 cm, CSPW 1.0 cm, TVW 0.3 cm, CMW (male 1.1 cm, female 1.0 cm). Conclusions: The normal fetal ventricles and cisterna magna are increased with the GA in the second and third trimesters. TVW and CMW are related to fetal gender. The establishment of normal reference values of fetal ventricles and cisterna magna based on GA and fetal gender are conducive to enhance the accuracy of MRI prenatal diagnosis.

Abstract
Objective: To evaluate the tolerability and short-term efficacy of chemo-radiotherapy in 125 patients with stage ⅡB-ⅣA esophageal carcinoma after radical resection. Methods: We retrospectively evaluated the rate of completion, toxicity and survival of patients undergoing adjuvant concurrent chemo-radiotherapy after radical resection of esophageal carcinoma from January 2004 to December 2014 in our institution. The survival rate was determined by the Kaplan-Meier method and analyzed using the log-rank test. Multivariate prognostic analysis was performed using the Cox proportional hazard model. Results: 122 patients received more than 50 Gy dose (97.6%). A total of 52 patients received more than 5 weeks chemo-radiotherapy (41.6%), while 73 patients underwent only 1-4 weeks (58.4%). The median following up was 48.4 months. 8 patients lost follow up (6.4%). The 1-year and 3-year overall survival rate were 91.6% and 57.0%, respectively, with a median survival time of 64.4 months. The 1-year and 3-year disease free survival rate were 73.2% and 54.3%, respectively, with a median disease free survival time of 59.1 months. The most common acute complications associated with chemo-radiotherapy were myelosuppression, radiation esophagitis and radiation dermatitis, the majority of which were Grade 1-2. Of the 125 patients, there were 59 cases of recurrence, including 23 cases with local regional recurrence, 26 cases with hematogenous metastasis, and 8 cases with mixed recurrence. Univariate analysis showed that the numbers of concurrent chemotherapy was associated with the overall survival (P=0.006). But receiving more than 5 weeks was not the prognostic factor compared to 1 to 4 weeks chemotherapy (P=0.231). Multivariate analysis showed that only the numbers of concurrent chemotherapy was an independent prognostic factor (P=0.010). Conclusions: Postoperative radiotherapy concurrent with weekly chemotherapy could improve the overall survival and decrease the recurrence for stage ⅡB-ⅣA esophageal carcinoma after radical resection. However, the completion rate of chemotherapy was low, so it was necessary to explore reasonable regimens to improve the completion rate and carry out prospective randomized controlled trial.

Abstract
Objectives: To propose a novel clinical classification system of gallbladder cancer, and to investigate the differences of clinicopathological characteristics and prognosis based on patients who underwent radical resection with different types of gallbladder cancer. Methods: The clinical data of 1 059 patients with gallbladder cancer underwent radical resection in 12 institutions in China from January 2013 to December 2017 were retrospectively collected and analyzed.There were 389 males and 670 females, aged (62.0±10.5)years(range:22-88 years).According to the location of tumor and the mode of invasion,the tumors were divided into peritoneal type, hepatic type, hepatic hilum type and mixed type, the surgical procedures were divided into regional radical resection and extended radical resection.The correlation between different types and T stage, N stage, vascular invasion, neural invasion, median survival time and surgical procedures were analyzed.Rates were compared by χ(2) test, survival analysis was carried by Kaplan-Meier and Log-rank test. Results: Regional radical resection was performed in 940 cases,including 81 cases in T1 stage,859 cases in T2-T4 stage,119 cases underwent extended radical resection;R0 resection was achieved in 990 cases(93.5%).The overall median survival time was 28 months.There were 81 patients in Tis-T1 stage and 978 patients in T2-T4 stage.The classification of gallbladder cancer in patients with T2-T4 stage: 345 cases(35.3%)of peritoneal type, 331 cases(33.8%) of hepatic type, 122 cases(12.5%) of hepatic hilum type and 180 cases(18.4%) of mixed type.T stage(χ(2)=288.60,P<0.01),N stage(χ(2)=68.10, P<0.01), vascular invasion(χ(2)=128.70, P<0.01)and neural invasion(χ(2)=54.30, P<0.01)were significantly correlated with the classification.The median survival time of peritoneal type,hepatic type,hepatic hilum type and mixed type was 48 months,21 months,16 months and 11 months,respectively(χ(2)=80.60,P<0.01).There was no significant difference in median survival time between regional radical resection and extended radical resection in the peritoneal type,hepatic type,hepatic hilum type and mixed type(all P>0.05). Conclusion: With application of new clinical classification, different types of gallbladder cancer are proved to be correlated with TNM stage, malignant biological behavior and prognosis, which will facilitate us in preoperative evaluation,surgical planning and prognosis evaluation.

Abstract
Objective: To investigate the association between sleep duration and brachial-ankle pulse wave velocity (baPWV). Methods: A cross-sectional study method was used to observe 38 604 employees of Kailuan Group who participated in the physical examination and the baPWV test from January 2010 to July 2018. The age was (51.6±11.1) years old. There were 72.4% (27 955/38 604) male participants. According to the sleep duration, subjects were divided into 5 groups including ≤ 5 hours group (3 762 cases),>5 hours and ≤6 hours group (9 585 cases),>6 hours and ≤7 hours group (12 604 cases), >7 hours and ≤8 hours group (11 921 cases) and >8 hours group (732 cases). Multivariate logistic regression model was used to analyze the association between sleep duration and the baPWV. Results: The age was (51.6±11.1) years old. There were 72.4% (27 955/38 604) male participants. The prevalence of baPWV≥14 m/s in ≤ 5 hours group, >5 hours and ≤6 hours group, >6 hours and ≤7 hours group, >7 hours and ≤8 hours group, and >8 hours group was 63.5% (2 389/3 762), 58.9% (5 645/9 585), 55.0% (6 926/12 604), 53.3% (6 356/11 921) and 54.8% (401/732) respectively. After adjusting for confounding factors including age, gender, smoking, drinking, physical exercise, snoring, hypertension, diabetes mellitus, dyslipidemia, body mass index≥24 kg/m(2), mean arterial pressure, heart rate, and C-reactive protein, the multivariate logistic regression analysis showed that the OR were 1.48 (95%CI 1.29-1.70, P<0.01) and 1.18 (95%CI 1.07-1.30, P<0.01) respectively for baPWV≥14 m/s in ≤ 5 hours and >5 hours and ≤6 hours group when compared with >7 hours and ≤ 8 hours group. Conclusion: Short sleep duration is associated with elevated baPWV in mid-aged Chinese population.

Abstract
Objective: To investigate the effect of excimer laser coronary atherectomy (ELCA) in the interventional treatment of acute coronary syndrome (ACS). Methods: This prospective study enrolled 31 patients with ACS who underwent ELCA treatment in our hospital from November 8, 2016 to December 13, 2017. The efficacy and complications of ELCA were observed, and patients were followed up for postoperative observation of major adverse cardiovascular and cerebrovascular events (including target vessel revascularization, stroke, stent thrombosis, coronary artery bypass grafting, and death). Results: The patients were aged (65.0±10.8) years old and 25 were males (80.6%).There were 5 cases (16.1%) ST-segment elevation myocardial infarction, 3 cases (9.7%) non-ST-segment elevation myocardial infarction, and 23 cases (74.2%) unstable angina in this cohort.There were 9 cases (29.0%) in-stent restenosis, 11 cases (35.5%) saphenous vein graft, 2 cases (6.5%) chronic total occlusive disease, and 4 cases (12.9%) calcification.Two patients with chronic complete occlusive disease and 1 patient with calcified lesion were examined by intravascular ultrasound (IVUS). The other lesions were not examined with IVUS and optical correlation tomography (OCT).The ELCA success rate was 100% (31/31) and the PCI success rate was 100% (31/31).Intraoperative use of 0.9 mm diameter catheters accounted for 38.7% (12/31), 1.7 mm diameter catheters accounted for 32.3% (10/31), and 1.4 mm diameter catheters accounted for 29.0% (9/31).One patient with ST-segment elevation myocardial infarction experienced no reflow of coronary artery during operation. The other 30 patients had no complications such as perforation, small dissection, large dissection, distal occlusion, slow blood flow and collateral occlusion. One cardiac death(3.2%) occurred during the postoperative follow-up of (6.4±1.9) months. Conclusion: Our preliminary study results indicate that the use of ELCA in the interventional therapy of ACS is safe and effective.

Abstract
The mechanisms underlying neurodevelopmental damage caused by virus infections remain poorly defined. Congenital human cytomegalovirus (HCMV) infection is the leading cause of fetal brain development disorders. Previous work has linked HCMV infection to perturbations of neural cell fate, including premature differentiation of neural progenitor cells (NPCs). Here, we show that HCMV infection of NPCs results in loss of the SOX2 protein, a key pluripotency-associated transcription factor. SOX2 depletion maps to the HCMV major immediate early (IE) transcription unit and is individually mediated by the IE1 and IE2 proteins. IE1 causes SOX2 downregulation by promoting the nuclear accumulation and inhibiting the phosphorylation of STAT3, a transcriptional activator of SOX2 expression. Deranged signaling resulting in depletion of a critical stem cell protein is an unanticipated mechanism by which the viral major IE proteins may contribute to brain development disorders caused by congenital HCMV infection.IMPORTANCE Human cytomegalovirus (HCMV) infections are a leading cause of brain damage, hearing loss, and other neurological disabilities in children. We report that the HCMV proteins known as IE1 and IE2 target expression of human SOX2, a central pluripotency-associated transcription factor that governs neural progenitor cell (NPC) fate and is required for normal brain development. Both during HCMV infection and when expressed alone, IE1 causes the loss of SOX2 from NPCs. IE1 mediates SOX2 depletion by targeting STAT3, a critical upstream regulator of SOX2 expression. Our findings reveal an unanticipated mechanism by which a common virus may cause damage to the developing nervous system and suggest novel targets for medical intervention.

Abstract
OBJECTIVE To evaluate the effect of computer aided design and computer aided manufacture (CAD/CAM) one-piece zirconia posts and cores for the restoration of defective teeth. METHODS In the study, 72 defective teeth of 47 patients who had proper root canal therapy were restored with CAD/CAM one-piece zirconia posts and cores. All the ceramic crowns were finally used to restore contour and function of the teeth. The defective teeth were divided into two groups on the basis of the teeth defect degree. Group A: 39 defective teeth presented with three or four coronal residual walls, and group B: 33 defective teeth presented with less than two coronal residual walls. During the clinical observation period, the stability, dislocation of posts and the occurrence of fractures in either teeth or posts and cores were assessed and analyzed with a paired t test(α=0.05). Meanwhile shade matching was conducted between the restored teeth and normal reference teeth, the marginal fitness of the restored teeth were recorded according to the standard of United States Public Health Service (USPHS) and analyzed with descriptive statistics. RESULTS The average follow up was (65.0±4.8) months. During the observation period, the restorations were examined both clinically and with periapical radiograph. No incidence of teeth fracture or posts and cores complications were observed in both groups, and all CAD/CAM one-piece zirconia posts and cores remained intact with restored teeth. There were no post and core dislodgement or fracture. There was no difference between group A and group B (P>0.05). The restorative effect of CAD/CAM one-piece zirconia posts and cores with all the ceramic crowns were assessed according to the standard of USPHS, and the number of the restored tooth shade matching with level A was 67, and 5 with level B. The rate of shade matching was 93.06%. As the marginal fitness, 64 restored teeth were level A, and 8 with level B. The rate of restorative teeth marginal fitness was 88.89%. CONCLUSION CAD/CAM one-piece zirconia posts and cores were successfully used to restore defective teeth and received excellent clinical effect. So, it can be a good choice for defective teeth which need post-cores and crowns restoration.

Abstract
Objective: The aim of this retrospective study was to evaluate the prognostic significance of pretreatment Neutrophil-to-Lymphocyte Ratio(NLR) in locally advanced non-small cell lung cancer(NSCLC) patients treated with thoracic radiotherapy. Methods: We retrospectively analyze 420 patients who received thoracic radiotherapy alone, sequential chemoraiotherapy or concurrent chemoradiotherapy for locally advanced stage NSCLC from January 2007 to December 2010 of our hospital. The patients were divided into two groups (high NLR group and low NLR group) with appropriate cutoff point using the receiver operating characteristic (ROC) curve method. The survival curve was established by Kaplan-Meier method. The Log-rank test was used to compare the survival of the two NLR groups and the multivariate analysis was carried out by Cox regression model. Results: Among the 420 patients, 99 received radiotherapy alone, 139 received sequential chemoradiotherapy and 182 received concurrent chemoradiotherapy. 345 patients died and 75 were still alive. The median follow-up time was 5.2 years and the median overall survival was 22 months. The cut-off value of pretreatment NLR was 2.1. The 5-year PFS and OS rates in high NLR group and low NLR group were 10.6% vs 15.7% (P=0.033) and 15.5% vs 22.7% (P=0.012). Multivariate analysis confirmed that pretreatment NLR (hazard ratio 1.06, P=0.041) was independent prognostic factor of OS. Conclusions: Our study revealed that the pretreatment NLR is the independent prognostic factor of OS in patients with locally advanced stage NSCLC treated with thoracic radiotherapy. However, NLR is still greatly influenced by patient's condition and treatment which needs further research.
