Abstract
OBJECTIVES The aim of this study was to examine the disease burden of lung cancer attributable to particulate matter (PM2.5) pollution in China from 1990 to 2019. STUDY DESIGN Data from the Global Burden of Disease Study 2019 were used to estimate the disease burden of tracheal, bronchus and lung cancer attributed to PM2.5 over time in China. METHODS Joinpoint regression models were applied to disability-adjusted life years (DALYs) to assess the time trends and estimate the impact of PM2.5 on the overall disease burden of lung cancer. Furthermore, age-period-cohort models were conducted to assess the relationships between lung cancer DALYs attributed to PM2.5 exposure and age, calendar period and birth cohort trends in China from 1990 to 2019. RESULTS Lung cancer DALYs attributable to household air pollution from solid fuels decreased with an average annual percent change (AAPC) of 2.9 % per 100,000 population, while those attributable to ambient particular matter pollution (APE) increased (AAPC: -4.7 % per 100,000 population) over the past 30 years. The burden of lung cancer in terms of DALYs in males was higher than in females, and it demonstrated an age-dependent increase. The period and cohort effects also had significant impacts on the DALYs rates of lung cancer attributable to APE, indicating an overall increase in lung cancer DALYs for all age groups in each year. CONCLUSIONS This study highlights the need for effective strategies to reduce PM2.5 exposure in China, particularly from outdoor sources. Gender differences and age, period and cohort effects observed in the study provide valuable insights into long-term trends of lung cancer burden attributed to PM2.5.

Abstract
Climate dictates wildfire activity around the world. But East and Southeast Asia are an apparent exception as fire-activity variation there is unrelated to climatic variables. In subtropical China, fire activity decreased by 80% between 2003 and 2020 amid increased fire risks globally. Here, we assessed the fire regime, vegetation structure, fuel flammability and their interactions across subtropical Hubei, China. We show that tree basal area (TBA) and fuel flammability explained 60% of fire-frequency variance. Fire frequency and fuel flammability, in turn, explained 90% of TBA variance. These results reveal a novel system of scrubland-forest stabilized by vegetation-fire feedbacks. Frequent fires promote the persistence of derelict scrubland through positive vegetation-fire feedbacks; in forest, vegetation-fire feedbacks are negative and suppress fire. Thus, we attribute the decrease in wildfire activity to reforestation programs that concurrently increase forest coverage and foster negative vegetation-fire feedbacks that suppress wildfire.

Abstract
BACKGROUND The global and national burden of rheumatic mitral valve disease (MVD) has been well studied and estimated before. However, little is known about non-rheumatic degenerative MVD. Therefore, this study aimed to assess the trends in non-rheumatic degenerative MVD (NRDMVD) epidemiology, with an emphasis on NRDMVD mortality, leading risk factors, and their associations with age, period, and birth cohort. METHODS Using the data derived from the Global Burden of Disease Study 2019, including prevalence, mortality, and disability-adjusted life years, we analyzed the burden of NRDMVD and the detailed trends of NRDMVD mortality over the past 30 years in 204 countries and territories by implementing the age-period-cohort framework. RESULTS Globally, the number of deaths due to NRDMVD increased from 5695.89 (95% uncertainty interval [UI]: 5405.19 to 5895.4) × 1000 in 1990 to 9137.79 (95% UI: 8395.68 to 9743.55) × 1000 in 2019. The all-age mortality rate increased from 106.47 (95% UI: 101.03 to 110.2) per 100,000 to 118.1 (95% UI: 108.51 to 125.93) per 100,000, whereas the age-standardized mortality rate decreased from 170.45 (95% UI: 159.61 to 176.94) per 100,000 to 117.95 (95% UI: 107.83 to 125.92) per 100,000. The estimated net drift of mortality per year was -1.1% (95% confidence interval: -1.17 to -1.04). The risk of death due to NRDMVD increased with age, reaching its peak after 85 years old globally. Despite female patients being associated with lower local drift than male patients, no significant gender differences were observed in the age effect across countries and regions for all sociodemographic index (SDI) levels, except low-SDI regions. CONCLUSIONS We estimated the global disease prevalence of and mortality due to NRDMVD over approximately a 30-year period. The health-related burden of NRDMVD has declined worldwide; however, the condition persisted in low-SDI regions. Moreover, higher attention should be paid to female patients.

Abstract
Background Anomalous papillary muscle (APM) insertion into the mitral valve leaflet is rare but clinically important in hypertrophic obstructive cardiomyopathy (HOCM). In this study, we report the detection rate of APM insertion into the mitral valve using preoperative imaging modalities and the surgical outcomes of the patients. Methods By retrospectively reviewing the clinical records of patients with HOCM who underwent surgical treatment by a single operation group at our center from January 2020 to June 2023, patients with APM insertion into the mitral valve leaflet were identified. Baseline data, image characteristics, and surgical outcomes were analyzed. Results The incidence of APM insertion into the mitral valve leaflet was 5.1% (8/157). The insertion site was located at A3 in six cases, which was more common than at A2 (n = 2). Preoperative echocardiography was used to identify two patients (25%) with APM insertion. We observed a particular echocardiographic feature for APM in HOCM patients, which was noted as a "lip nevus sign", with a higher detection rate (62.5%). All patients successfully underwent septal myectomy with concomitant APM excision or mitral valve replacement via the transaortic (n = 5) or transmitral (n = 3) approach. The mean age was 49.0 ± 17.4 years and seven patients (87.5%) were female. Interventricular septum thickness (17.0 mm vs. 13.3 mm, P = 0.012) and left ventricular outflow gradient (117.5 mmHg vs. 7.5 mmHg, P = 0.012) were significantly decreased after surgery. Residual outflow obstruction, systolic anterior motion, and ≥3+ mitral regurgitation were negative. During the follow-up of 26.2 ± 12.2 months, there were no reported operations, adverse events, mitral regurgitation aggravations, recurrences of outflow obstruction, or instances of SAM. Conclusions Papillary muscles inserted into the mitral valve leaflet are a subtype of subvalvular malformation in HOCM that requires surgical correction. The lip nevus sign on echocardiography is a characteristic of APM insertion in HOCM and may improve the preoperative detection rate. Adequate myectomy with anomalous papillary muscle excision has achieved good results in reducing the outflow gradient and eliminating mitral regurgitation, with good outcomes at short-to-intermediate follow-up.

Abstract
Objective This study aimed to compare clinical outcomes of different mitral valve (MV) management methods in thoracoscopic transmitral myectomy (TTM) and guide surgeons' decision making for hypertrophic obstructive cardiomyopathy (HOCM). Methods Seventy-three consecutive patients (41 females; mean age, 53.7 ± 13.6 years) with HOCM who underwent TTM between January 2019 and October 2022 were enrolled and divided into 3 groups according to MV surgical strategy. Clinical outcomes were analyzed and compared among the groups. Results None of the patients experienced postoperative residual left ventricular outflow tract obstruction. Percentages of patients with mitral regurgitation (MR) grade ≥3+ (57.5% vs 1.4%) and systolic anterior motion (95.9% vs 2.7%) were significantly decreased postoperatively (P < .001 for both). The preoperative anterior mitral leaflet length was longer in patients in the anterior mitral leaflet direct reattachment group (median, 2.9 cm [interquartile range (IQR), 2.7-3.3 cm] vs 2.7 [IQR, 2.4-2.9 cm]; P = .018), but the postoperative coaptation length was shorter (mean, 8.3 ± 2.1 mm vs 11.1 ± 3.8 mm; P = .038). After a median echocardiography follow-up of 11.8 months, the left ventricular outflow tract gradient (LVOTG) and mitral regurgitation grades remained significantly improved in all 3 groups (P < .05 for all). Conclusions Total TTM in selected patients is safe and effective, and all 3 MV management strategies can significantly reduce the LVOTG while improving MR. Mitral valvuloplasty is the preferred initial management strategy over valve replacement except in the scenario of irreparable intrinsic MV disease and valvuloplasty failure.

Abstract
BACKGROUND Coronary arteries drain into the left ventricle, known as coronary-left ventricular fistula (CLVF), an extremely rare anomalous coronary artery disease. Little is known about the outcomes following transcatheter closure (TC) or surgical closure (SC) of CLVF. METHOD This was a single-center retrospective study including 42 consecutive patients who underwent either the TC or SC procedure from January 2011 to December 2021. The baseline and anatomic characteristics of the fistulas, procedural outcomes, and late outcomes were summarized and analyzed. RESULTS The mean age was 31.6 ± 16.2 years, with 28 male patients (66.7%). Fifteen patients underwent SC group and the remaining received TC group. There were no differences in age, comorbidities, clinical presentations, and anatomic characteristics between the 2 groups. The procedural success rate was similar (93.3% vs. 85.2%, P = 0.639) without operative and in-hospital mortality in both groups. Notably, patients who underwent TC had a significantly shorter postoperative in-hospital length of stay (2.11 ± 1.49 vs. 7.73 ± 2.37 days, P<0.001). The median follow-up time was 4.6 years (2.5-5.7 years, TC group) and 3.98 years (0.42-7.15 years, SC group), respectively. No difference was observed in the incidence of recanalization of the fistula (7.4% vs. 6.7%, P = 1) and myocardial infarction (0% vs. 0%). Cerebral infarction due to discontinuation of anticoagulants happened to two patients in the TC group. Importantly, thrombotic occlusion of the fistulous tract with patent parent coronary artery was found in 7 patients of the TC group. CONCLUSION Both transcatheter and SC are safe and effective for patients with CLVF. Thrombotic occlusion is a noteworthy late complication, and its presence indicates the use of anticoagulants lifelong.

Abstract
OBJECTIVE The study aims to present a 15-patient case series of tracheal extubation in the prone position after endoscopic retrograde cholangiopancreatography (ERCP) general anesthesia. PATIENTS AND METHODS Fifteen inpatients who underwent elective ERCP in our hospital were prospectively enrolled, and a series of case studies were conducted with the prone extubation technique after general anesthesia. All patients underwent routine operation of tracheal intubation under general anesthesia. After the surgery, when the train-of-four ratio (TOFr) ≥0.9, bispectral index (BIS) ≥80, tidal volume ≥6 ml/kg and the required actions could be performed, the endotracheal catheter was removed after sufficient negative pressure suction of oral secretions. After the endotracheal catheter was removed, the patient autonomously turned to the transport bed with the assistance of medical staff and was then admitted to the post-anesthesia care unit (PACU) for further observation. When the patient awoke, he had regained orientation, and presented stable vital signs, no nausea and vomiting, and no other discomfort symptoms, he/she was able to leave PACU and returned to the ward with a Steward score of ≥5. RESULTS All 15 patients who underwent ERCP elective surgery were successfully extubated in the prone position after surgery. Transient hypoxemia with SpO2 below 90% occurred in 2 of the 15 patients and returned to normal with oxygen mask administration. 7 patients had coughs and were without special treatment. Another 1 patient showed transient abnormal hemodynamic fluctuations after extubation, mean airway pressure (MAP) was higher than 20% of the baseline value, and hemodynamics was stable after drug treatment. CONCLUSIONS The prone extubation technique is feasible for ERCP general anesthesia patients. However, a larger sample size is needed to validate its safety and to verify whether there exist advantages of the extubation technique in a prone position over a supine position.

Abstract
BACKGROUND Pure aortic valve disease is common and has been treated with sternotomy aortic valve replacement for decades. Minimally invasive cardiac surgery has been widely used in atrioventricular valve lesions, but totally thoracoscopic aortic valve replacement has rarely been reported. METHOD The profiles of 9 patients who were diagnosed with severe aortic valve diseases and treated with two-port thoracoscopic aortic valve replacement between February 2021 and February 2022 were retrospectively reviewed. The clinical data, including baseline characteristics, operative data, postoperative complications, and short-term outcomes, were reported. RESULTS All nine patients successfully underwent two-port thoracoscopic aortic valve replacement, with a cardiopulmonary bypass time of 137.56 ± 27.99 min and an aortic cross-clamp time of 95.33 ± 17.96 min. Seven (77.78%) patients underwent mechanical valve replacement, and two (22.22%) patients underwent bioprosthetic valve replacement. Two (22.22%) patients underwent a concomitant aortic root enlargement procedure. There were no intraoperative or postoperative deaths. The incidence of procedural complications was 0%, while the results of ventilation time, intensive care unit stay length, blood transfusion, chest tube drainage, and kidney function were satisfactory. CONCLUSION Two-port thoracoscopic aortic valve replacement is a safe and effective surgical treatment option for carefully selected patients with pure aortic valve diseases.

Abstract
OBJECTIVES Transaortic myectomy is a common procedure for patients with hypertrophic obstructive cardiomyopathy (HOCM). Thoracoscopic trans-mitral myectomy has been described in a few small-sample studies and has been recommended as preferable. We herein report our clinical outcomes using the thoracoscopic trans-mitral approach with 76 patients. METHODS A retrospective single-center analysis of the safety and efficacy of thoracoscopic trans-mitral myectomy by comparing the clinical outcomes with that of transaortic myectomy. RESULTS Between April 2019 and October 2021, 132 patients underwent either a transaortic (n = 56) or a thoracoscopic trans-mitral myectomy (n = 76). Compared with those in the transaortic group, patients in the trans-mitral group were more likely to be weaned off the ventilator within 24 h after surgery (80.3% vs 60.7%, P < 0.05) and to require a shorter duration of ventilation [29.01(43.91) h vs 51.12(94.96), P = 0.08] and lower transfusion rate (26.3% vs 48.2%, P < 0.05). The in-hospital mortality rate of the transaortic and trans-mitral groups was 3.6% (n = 2) and 1.3% (n = 1), respectively. No significant inter-group differences were observed regarding in-hospital mortality, the incidence of low cardiac output syndrome, or permanent pacemaker implantations. In the trans-mitral group, the thickness of the interventricular septum was significantly reduced postoperatively, with resultant relief of the left ventricular outflow tract obstruction [89.37(27.5) mmHg vs 10.51(0.65) mmHg, P < 0.01]. Transaortic myectomy also resulted in a significant reduction in left ventricular outflow tract gradient [90.41(33.31) mmHg vs 11.35(9.43) mmHg, P < 0.01]. And the incidence of residual SAM of the trans-mitral group and the transaortic group were 2.67% and 1.9%, respectively. CONCLUSIONS The thoracoscopic trans-mitral approach provides excellent exposure to the septum and anomalies of the mitral valve and papillary muscle. It relieves obstruction effectively, without increasing the incidence of major complications.

Abstract
BACKGROUND The transaortic Morrow procedure is the current gold standard for hypertrophic obstructive cardiomyopathy (HOCM) patients who are resistant to maximum drug therapy. It is controversial whether concomitant mitral valve intervention is necessary. Only a few centers apply for concomitant anterior mitral leaflet extension with a bovine or autologous pericardial patch to further decrease systolic anterior motion. Our aim is to assess the primeval outcomes of thoracoscopic transmitral myectomy with anterior mitral leaflet extension (TTM-AMLE) in symptomatic HOCM patients. METHODS Between April 2019 and November 2020, 18 consecutive HOCM patients who underwent TTM-AMLE were enrolled in this study. Preoperative, postoperative, and follow-up outcomes were compared and statistically analyzed. RESULTS The mean age was (50.17 ± 6.18) years and 10 (55.56%) were males. 18 (100%) patients had mitral regurgitation preoperatively, and they all successfully underwent TTM-AMLE with a median cardiopulmonary bypass and aortic cross-clamp time of 200.0 (150.8, 232.0), and 127.5 (116.0, 149.0) min, respectively. The median length of ICU stay was 2.7 (1.4, 5.2) days. The interventricular septum thickness was significantly reduced (from 18.03 ± 3.02 mm to 11.91 ± 1.66 mm, p < .001). There was no perioperative mortality, perforation of ventricular septum, or conversion to sternotomy observed. During a median follow-up of 18 months (IQR, 5-24 months), 1 (5.56%) patient had severe mitral regurgitation due to patch detachment and received reoperation. Moderate degree of mitral regurgitation and more than 50 mmHg in left ventricular outflow tract gradient were found in 2 (11.11%), and 1 (5.56%) patients, respectively. 1 (5.56%) patient who had second-degree atrioventricular block received permanent pacemaker implantation postoperatively. Overall, the maximum left ventricular outflow tract gradient (88.50 [59.50, 112.75] mmHg vs. 10.50 [7.00, 15.50] mmHg, p = .002), left ventricular outflow tract velocity (4.70 [3.86, 5.33] m/s vs. 1.60 [1.33, 1.95] m/s, p < .001) and the degree of mitral regurgitation (6.99 ± 4.47 cm2 vs. 2.22 ± 1.51 cm2 , p = .001) were significantly decreased, with a significant reduction in the proportion of systolic anterior motion (94.44% vs. 16.67%, p < .001). CONCLUSIONS The TTM-AMLE is a safe and effective surgical approach for selected patients with HOCM. In our series, it provides excellent relief of left ventricular outflow tract obstruction, while significantly eliminating mitral regurgitation. The early outcomes of TTM-AMLE are satisfactory, but further studies and longer follow-ups are awaited.

Abstract
OBJECTIVE To explore whether the effect of low-frequency pulsed electromagnetic fields (PEMFs) in promoting osteoblast mineralization and maturation is related to the primary cilia, polycystin2 (PC2) and sAC/PKA/CREB signaling pathway. METHODS We detected the expression levels of PC2, sAC, PKA, CREB and their phosphorylated proteins in primary rat calvarial osteoblasts exposed to 50 Hz 0.6 mT PEMFs for 0, 5, 15, 30, 60, 90, and 120 min. We blocked PC2 function with amiloride hydrochloride and detected the changes in the activity of sAC/PKA/CREB signal pathway and the mineralization and maturation of the osteoblasts. These examinations were repeated in the osteoblasts after specific knockdown of PC2 via RNA interference and were the co-localization of PC2, sAC, PKA, CREB and their phosphorylated proteins with the primary cilia were using immunofluorescence staining. The expressions of PC2 and the signaling proteins of sAC/PKA/CREB pathway were detected after inhibition of primary ciliation by RNA interference. RESULTS The expression levels of PC2, sAC, p-PKA and p- CREB were significantly increased in the osteoblasts after exposure to PEMFs for different time lengths (P < 0.01). Blocking PC2 function or PC2 knockdown in the osteoblasts resulted in failure of sAC/PKA/CREB signaling pathway activation and arrest of osteoblast mineralization and maturation. PC2, sAC, p-PKA and p-CREB were localized to the entire primary cilia or its roots, but PKA and CREB were not detected in the primary cilia. After interference of the primary cilia, PEMFs exposure no longer caused increase of PC2 expression and failed to activate the sAC/PKA/CREB signaling pathway or promote osteoblast mineralization and maturation. CONCLUSION PC2, located on the surface of the primary cilia of osteoblasts, can perceive and transmit the physical signals from PEMFs and promote the mineralization and maturation of osteoblasts by activating the PC2/ sAC/PKA/CREB signaling pathway.

Abstract
Background The thoracoscopic trans-mitral approach can not only facilitate exposure of the ventricular septum, mitral valve, and subvalvular apparatus, it also enables the surgeons to perform concomitant mitral valve intervention. This study aimed to determine the safety and efficacy of thoracoscopic trans-mitral septal myectomy in elderly patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods We reviewed the demographic to clinical characteristics and outcomes of patients who underwent thoracoscopic trans-mitral septal myectomy in our center between April 2019 and April 2021. The population was divided into a younger group (<60 years) and an elderly group (≥60 years). Results There were 46 and 20 patients in the younger and elderly groups, respectively. The majority of patients in the elderly group were female (39.1 vs. 80.0%, P < 0.01). Patients in the elderly group were more likely to be in New York Heart Association Class IV (2.2 vs. 80.0%, P < 0.01). The European System for Cardiac Operation Risk Evaluation II predicted mortality rates were significantly higher (3.97 ± 1.81 vs. 1.62 ± 0.86%, P < 0.01) in the elderly group. In the elderly group, a patient converted to median sternotomy due to left ventricular posterior free wall rupture following septal myectomy and mitral bioprosthetic valve replacement. The patient then underwent double-patch sandwich repair for rupture and mitral mechanical valve replacement and was eventually discharged. All patients in the elderly group were discharged, while one in the younger group died. No patient in the elderly group required permanent pacemaker implantation vs. one in the younger group. Patients in the elderly group were more likely to spend more time in the intensive care unit than those in the younger group (5.44 ± 5.80 days vs. 3.07 ± 2.72, P < 0.05). However, there was no significant intergroup difference in in-hospital mortality or complications. Importantly, the left ventricular outflow tract pressure gradient was significantly decreased from 96.15 ± 32.89 mmHg to 8.2 ± 3.42 mmHg with no residual obstruction in the elderly group. The interventricular septal thickness was significantly decreased from 19.73 ± 3.14 mm to 11.30 ± 2.23 mm. Postoperative mitral regurgitation severity was significantly improved in the elderly group. Conclusion This study demonstrated that thoracoscopic trans-mitral septal myectomy is a feasible option for selected elderly patients with satisfactory outcomes similar to those of young patients.

Abstract
OBJECTIVE To identify traditional Chinese drugs that contain active ingredients for treatment of myocardial infarction (MI) and explore their therapeutic mechanisms using network pharmacology and molecular docking technology. METHODS The TCMSP database was used for screening the traditional Chinese drugs containing active ingredients for treating MI, and the related targets of MI and the candidate drugs were obtained from Genecards, OMIM, PharmGkb and PharmMapper databases. The common target network of the drug targets and disease targets was established using Venny2.1.0 software. GO and KEGG signal pathway enrichment analysis of the common targets was performed, and the protein-protein interaction (PPI) network was constructed for the targets. The targets in the PPI network were analyzed to identify the key targets, for which GO and KEGG pathway enrichment analyses were performed. Molecular docking was performed for the candidate ingredients and the key targets, and a total score ≥6 was used as the criteria for screening the therapeutic ingredients and their docking binding with key targets was verified. A human umbilical vein endothelial cell (HUVEC) model of oxygen-glucose deprivation (OGD) was used to validate the candidate ingredients and the key therapeutic targets for MI by Western blotting. RESULTS Our analysis identified Salvia miltiorrhiza and Dalbergiae odoriferae as the candidate drugs rich in active ingredients for treatment of MI. These ingredients involved 16 key therapeutic targets for MI, which participated in such biological processes as inflammatory response, angiogenesis, energy metabolism and oxidative stress and the pathways including HIF-1, VEGF, and TNF pathways. Sclareol and PTGS2 in Salvia miltiorrhiza and formononetin and KDR in Dalbergiae odoriferae all had high docking total scores. Western blotting showed that at medium and high doses, sclareol significantly inhibited PTGS2 expression and formononetin promoted KDR expressions in the cell models in a dose-dependent manner (P < 0.05). CONCLUSION Both Salvia miltiorrhiza and Dalbergiae odoriferae have good therapeutic effects on MI. Sclareol in Salvia miltiorrhiza and formononetin in Dalbergiae odoriferae regulate the expressions of KDR and PTGS2, respectively, to modulate the inflammatory response, angiogenesis, oxidative stress and energy metabolism and thus produce myocardial protective effects.

Abstract
Persistent left superior vena cava (PLSVC) is a relatively rare congenital anomaly in the general population. It plays an important role in initiating and maintaining atrial fibrillation (AF) in some patients. Radiofrequency catheter ablation is the major treatment for patients with AF and PLSVC in most publications. Here, we reported a case of thoracoscopic ablation for a patient with atrial fibrillation and persistent left superior vena cava. After preprocedural simulation using virtual reality, we successfully completed box-lesion, ablation line from superior vena cava to inferior vena cava, left atrial appendage (LAA) excision, and PLSVC ablation. It provides a new perspective on surgical treatment for patients with AF and PLSVC.

Abstract
Objective: To investigate the effect and mechanism of exosomes derived from human amniotic epithelial cells (hAEC-Exos) on the proliferation and migration of HaCaT in high glucose environment. Methods: The experimental research method was adopted. The amniotic membrane tissue was collected from 10 healthy pregnant women at full term delivery in the Department of Obstetrics and Gynecology of Fujian Medical University Union Hospital from January to June 2019, and the primary human amniotic epithelial cells (hAECs) were isolated. The growth status and morphological changes of the primary hAECs on the 2nd, 4th, and 7th day of culture were observed, and the expressions of the cells surface markers of CD73, CD90, CD29, CD34, and human leukocyte antigen DR (HLA-DR). The 2nd to 4th passages of hAECs were used in the following experiments. The hAEC-Exos were separated by ultracentrifugation method. The HaCaT and hAEC-Exos were co-cultured for 3 h, and the uptake of hAEC-Exos by HaCaT was observed by inverted fluorescence microscopy. The HaCaT were divided into phosphate buffer solution (PBS) group and hAEC-Exos group or dimethyl sulfoxide (DMSO)+PBS group, DMSO+hAEC-Exos group, and LY294002+hAEC-Exos group, which were dealt correspondingly, with 3 wells in each group. Cell counting kit 8 (CCK-8) method was used to detect cell proliferation activity after 0 (immediately), 12, 24, 36, 48, and 60 h of culture. The scratch test was conducted to detect the scratch healing at 0, 24, 48, and 72 h after the scratch, and the scratch healing rate was calculated, respectively. The Transwell experiment was conducted to detect the number of transmembrane cells after 48 h of culture. The Western blotting was used to detect the protein expressions of mammalian target of rapamycin (mTOR), phosphorylated mTOR (p-mTOR), protein kinase B (Akt), and phosphorylated Akt (p-Akt) related to phosphatidylinositol 3-kinase-Akt-mTOR (PI3K-Akt-mTOR) pathway after 24 h of culture. Data were statistically analyzed with analysis of variance for repeated measurement, one-way analysis of variance, and independent sample t test. Results: Most of the primary hAECs were oval and uniform in size on the 2nd day of culture. The hAECs were arranged in a typical cobblestone-like monolayer on the 4th and 7th day of culture. The primary hAECs highly expressed CD73, CD90, and CD29 of mesenchymal stem cell related surface markers, and were with no or low expressions of CD34 and HLA-DR of hematopoietic stem cell related surface markers. After 3 h of culture, hAEC-Exos were successfully endocytosed by HaCaT into the cytoplasm and gathered around the nucleus. After 12, 24, 36, 48, and 60 h of culture, the proliferation activity of HaCaT in hAEC-Exos group was significantly higher than that in PBS group (t=3.691, 10.861, 12.121, 10.531, 14.931, P<0.01). At 24, 48, and 72 h after scratch, the scratch healing rates of HaCaT in PBS group were significantly lower than those in hAEC-Exos group (t=3.342, 6.427, 5.485, P<0.05 or P<0.01). After 48 h of culture, the number of transmembrane HaCaT in hAEC-Exos group was significantly more than that in PBS group (t=5.385, P<0.01). After 24 h of culture, the protein expressions of p-mTOR and p-Akt in HaCaT of hAEC-Exos group were significantly higher than those in PBS group (t=4.240, 5.586, P<0.01), while the protein expressions of mTOR and Akt in HaCaT of the two groups were similar (P>0.05). After 24 h of culture, the protein expressions of p-mTOR and p-Akt in HaCaT of DMSO+hAEC-Exos group were significantly higher than those in DMSO+PBS group (t=6.155, 8.338, P<0.01) and LY294002+hAEC-Exos group (t=5.030, 3.960, P<0.01), while the protein expressions of mTOR and Akt in HaCaT of the three groups were similar (P>0.05). The proliferation activity of HaCaT in DMSO+hAEC-Exos group at 12, 24, 36, 48, and 60 h of culture was 0.78±0.05, 1.23±0.07, 1.60±0.09, 1.86±0.09, and 2.03±0.08, which was significantly higher than 0.46±0.04, 0.69±0.07, 0.98±0.08, 1.16±0.08, and 1.26±0.11 in DMSO+PBS group (t=4.376, 7.398, 8.488, 9.766, 10.730, P<0.01). The proliferation activity of HaCaT in DMSO+hAEC-Exos group at 24, 36, 48, and 60 h was significantly higher than 0.96±0.09, 1.20±0.08, 1.39±0.08, and 1.55±0.10 in LY294002+hAEC-Exos group (t=3.639, 5.447, 6.605, 6.693, P<0.05 or P<0.01). The scratch healing rates of HaCaT in DMSO+hAEC-Exos group at 24, 48, and 72 h after scratch were significantly higher than those in DMSO+PBS group (t=4.003, 6.349, 7.714, P<0.01) and LY294002+hAEC-Exos group (t=3.805, 4.676, 4.067, P<0.05 or P<0.01). After 48 h of culture, the number of transmembrane HaCaT in DMSO+hAEC-Exos group was significantly more than that in DMSO+PBS group and LY294002+hAEC-Exos group, respectively (t=7.464, 1.232, P<0.01). Conclusions: PI3K-Akt-mTOR pathway can promote the proliferation and migration of HaCaT in high glucose environment by mediating hAEC-Exos.

Abstract
Patients highly vulnerable for COVID-19 infection have been proposed to take priority for vaccination. However, vaccine hesitancy is usually more prevalent in these patients. Investigation around modifiable contributors of vaccine hesitancy plays a pivotal role in the formulation of coping strategies. We aimed to evaluate the impact of vaccine misconception in patients with lung cancer or pulmonary ground-glass opacity (GGO). A web-based questionnaire was constructed based on a qualitative interview with 15 patients and reviewed by a multidisciplinary expert panel. Six Likert five-scale questions were used to generate a score of vaccine misconception (SoVM), which ranged from 0 to 24 points, with a higher score indicating a higher level of misconception. A total of 61.6% (324/526) patients responded to our questionnaire. A higher proportion of low willingness patients (n = 173), compared to high willingness patients (n = 151), disagreed that cancer patients should be prioritized for COVID-19 vaccination (82.1% vs. 50.3%, p < .001) and perceived themselves to have contraindications (45.7% vs. 15.9%, p < .001). The mean SoVM was significantly lower in the high willingness group than the low willingness group (9.9 vs. 13.0, p < .001). Among the unvaccinated patients, the SoVM increased as the willingness to be vaccinated decreased (p < .0001). In multivariable logistic regression, patients with higher SoVM (OR 0.783, 95% CI 0.722-0.848), being female (OR 0.531, 95% CI 0.307-0.918) or diagnosed with lung cancer (OR 0.481, 95% CI 0.284-0.814) were independently associated with a lower willingness to be vaccinated against COVID-19. Receiver operating characteristic curve suggested that a SoVM of 11 yielded the best discrimination for predicting the willingness to receive COVID-19 vaccine (AUC = 0.724). The study findings reveal that patient misconception significantly contributes to vaccine hesitancy and needs to be addressed by evidence-based education tailored to their specific concerns.

Abstract
OBJECTIVES This review aimed to evaluate the safety and efficacy of concomitant surgical ablation (SA) for patients with atrial fibrillation (AF) undergoing rheumatic mitral valve (MV) surgery. METHODS A systematic search of relevant studies focusing on SA for patients with AF undergoing rheumatic MV surgery was performed. The primary outcomes included mortality, efficacy, and complications. RESULTS Four randomized controlled trials (RCTs) and four observational studies covering 1931 patients met the inclusion criteria. In RCTs, no significant differences in reoperation for bleeding, low cardiac output syndrome, thromboembolic events, and early (risk ratio [RR], 2.07; 95% confidence intervals [CI], 0.37-11.40; p = .41) and midterm all-cause death (RR, 1.07; 95% CI, 0.40-2.88; p = .89) were noted between the SA group and the nonablation group. These results were similar to those obtained from observational studies. However, ablation was associated with a higher incidence of permanent pacemaker implantation (RR, 2.44; 95% CI, 1.15-5.18; p = .02) in observational studies but not in RCTs (RR, 2.03; 95% CI, 0.19-21.26; p = .56). Furthermore, additional SA was significantly more effective in sinus rhythm (SR) restoration than MV surgery alone at discharge and at the 12-month and 3-year follow-ups. CONCLUSIONS Concomitant SA during rheumatic MV surgery does not increase perioperative adverse events. In addition, SA promotes considerable restoration of SR. Although some evidence exists that permanent pacemaker implantation is more common after ablation, not all studies support this notion.

Abstract
BACKGROUND Failed mitral bioprosthesis has conventionally been treated with redo surgical mitral valve replacement (SMVR). Transcatheter mitral valve-in-valve implantation (TM-VIVI) is emerging as an alternative to SMVR in high-risk patients. We report our experience with transapical TM-VIVI using the J-Valve system. METHODS From May 2020 to January 2021, 21 patients with a failed mitral bioprosthesis underwent transapical TM-VIVI without concomitant procedures at Guangdong Provincial People's hospital. The mean age was 74.62 years. All patients were heavily symptomatic with severe mitral regurgitation and increased trans-prosthetic gradient. The Society of Thoracic Surgeons predicted risk of mortality (STS PROM) and European System for Cardiac Operative Risk Evaluation II (EuroScore II) scores were used and predicted high mortality (STS PROM, 12.91%±9.94%; EuroScore II, 12.04%±10.5%). All the procedures were performed in a hybrid room. RESULTS The success rate was 100% with no conversion to median sternotomy and no intraprocedural death. The mean ventilation time and intensive care unit (ICU) stay were 25±21.44 minutes and 4.14±7.08 days, respectively. No major postoperative complications were observed, except 1 patient suffered pneumonia and required tracheostomy. All patients recovered well. Postoperative echocardiography revealed excellent hemodynamics with no residual mitral regurgitation in 19 patients and mild regurgitation in 2 patients. In a subgroup analysis, no significant differences among procedural and postoperative outcomes were detected in patients with previous aortic-mitral double valve replacement (DVR) compared to other patients. CONCLUSIONS Our results demonstrate the safety and feasibility of transapical TM-VIVI using the J-Valve system, even in patients following DVR.

Abstract
BACKGROUND Transcatheter mitral valve-in-valve implantation (TM-VIV) has emerged as a viable and attractive alternative to surgical mitral valve replacement (SMVR). This study aimed to review a single-center experience with redo mitral procedure for mitral bioprostheses failure over an 8-year period. In addition, it compared procedural safety and early outcomes of various approaches. METHODS Between January 2013 and January 2021, 79 consecutive patients who underwent redo procedure for mitral bioprostheses failure in our institution were retrospectively reviewed. SMVR and transapical TM-VIV were performed in 54 and 25 patients, respectively. In the SMVR group, 12 patients underwent totally thoracoscopic redo mitral valve replacement (MVR). RESULTS The annual volume of procedures grew continuously during the study period, with the use of totally thoracoscopic redo MVR increasing from 0% in 2012 to 20% in 2019. In 2020, 84.2% of total procedures were performed via the transcatheter approach. Patients in the TM-VIV group were significantly older and had higher scores on the European System for Cardiac Operative Risk Evaluation II (EuroScore II) and the Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) (P<0.01). The in-hospital mortality for the SMVR group and TM-VIV group was 3.7% (2 patients) and 0, respectively. Compared to the SMVR group, TM-VIV was associated with shorter ventilation time, intensive care unit stay, and postoperative in-hospital stay, and there was less need for blood transfusion. In the subgroup analysis, no significant difference was detected among most perioperative outcomes between the totally thoracoscopy approach group and the TM-VIV group. CONCLUSIONS There is an increasing number of patients demanding surgical treatments for mitral bioprostheses failure. TM-VIV is playing a significant role due to its scope of application and excellent outcomes.

Abstract
INTRODUCTION Scrub typhus (ST) is an acute febrile infection and remains a significant health problem globally. This study aimed to determine the factors associated with ST infection in Luhe District, China. MATERIAL AND METHODS The case-control study was conducted among 116 cases identified through passive surveillance systems over three years.The control subjects were 232 living in the same village for more than six months without any history of ST infection were selected by matching to the age (within 5-years) and identified through active surveillance. Statistical analyses were performed using SPSS v. 25.0 for Windows (IBM SPSS, Chicago, IL, USA). RESULTS The mean age of confirmed persons was 58.1(SD=10.15) years, while control subjects were 56.14 (11.57).There is no significant difference in gender, age, education, and occupations between case and control. Farmers had the most significant number of cases among occupational groups. The three factors that were significantly associated with an increased odds of having ST infection are bundling or moving waste straw (OR: 1.94, 95%CI; 0.99,381), morning exercise in the park or field (OR: 4.74 95%CI; 1.19, 18.95), and working as labourer in the vegetable field (OR:1.02, 95%CI:1.02,3.19). CONCLUSIONS Our findings suggested establishing a prevention and control strategy for these groups to lower ST development risk.

Abstract
BACKGROUND This study aimed to summarize the perioperative and long-term outcomes of patients with previous mitral valve surgery (MVS) undergoing reoperative mitral valve replacement (MVR). METHODS Data for all reoperative mitral valve replacements (re-MVRs) with or without concomitant tricuspid surgery were analyzed from Guangdong Provincial People's Hospital between January 2013 and December 2019. Propensity score matching resulted in 30 matched pairs with improved balance after matching in baseline covariates. Perioperative data and long-term clinical outcomes were analyzed. RESULTS Results are based on the matched cohorts between the two groups. The in-hospital mortality was 3.3% (two deaths) in the entire cohort and was not significantly different between the median sternotomy (MS) group and the totally thoracoscopic (TT) group. Most patients in the TT group had their tracheal intubation removed within 24 hours of surgery. The TT group had a diminished requirement for blood transfusion and a reduced 4-day postoperative chest tube drainage amount. The incidence of early major complications, including all-cause death and reoperation due to bleeding, was lower in the TT group. No significant differences were observed in the 7-year survival probability between the two groups. CONCLUSIONS The encouraging results regarding the perioperative and long-term outcomes of patients who underwent a TT re-MVR show that this approach is particularly beneficial for patients requiring reoperation.

Abstract
Background The aims of the present study was to compare midterm results of quadrangular leaflet resection versus chordal replacement for the repair of degenerative posterior mitral leaflet (PML) prolapse, and to explore the risk factors for recurrent severe mitral regurgitation (MR). Methods From January 2012 to December 2018, 1,423 consecutive patients underwent mitral valve (MV) repair. A total of 317 had degenerative PML prolapse and constituted the study population. Of these, 74 (23.3%) underwent quadrangular leaflet resection, and 243 (76.7%) underwent chordal replacement. Outcomes were compared by using unadjusted data and propensity score-matched analyses. Results Patients with multiple leaflet prolapse were more likely to undergo chordal replacement (18.4% vs. 41.9%, P<0.001), and performed as a minimally invasive approach (47.3% vs. 61.7%, P=0.027). Of the entire cohort, 1 death (0.3%) occurred due to intraoperative aortic dissection, and 1 patient who had undergone chordal replacement required reoperation before discharge for posterior leaflet tearing. There was no significant difference in the probability of freedom from recurrent severe MR at 82 months between the resection and neochordae groups in both the pre-matched (95.6% vs. 88.8%, P=0.105) and matched (95.2% vs. 88.5%, P=0.170) cohorts, which was consistent across all of the examined subgroups (P>0.05). Multivariate Cox regression indicated that dilated left ventricular end-systolic diameter (LVESD) was an independent risk factor for recurrent severe MR [<40 vs. >40 mm, hazards ratio (HR): 3.17, 95% confidence interval (CI): 1.20–8.39, P=0.020]; however, surgical technique was not (resection vs. neochordae, HR: 0.31, 95% CI: 0.07–1.37, P=0.122). Conclusions Chordal replacement for the repair of degenerative posterior MV prolapse yields similar satisfactory outcomes when compared with quadrangular resection, and is promising in minimally invasive cardiac surgery for various lesions. However, it is also associated with more recurrent severe MR, albeit non-significant, for which patients with dilated LVESD are at high risk.

Abstract
BACKGROUND To objectively evaluate the feasibility, safety, effectiveness and short-term outcome of totally thoracoscopic mitral valve replacement via two port approach, we conducted a retrospective study comparing two port approach with three port approach for mitral valve replacement. METHODS Data for all thoracoscopic mitral valve replacement were analyzed from Guangdong Cardiovascular Institute between January 1, 2016 and December 31, 2017. To account for selection bias between two port approach and three approach, one-to-one propensity score caliper matching without replacement was performed. The clinical data of the two groups were collected, including preoperative cardiac function, operative data, postoperative complications, and short-term outcome. RESULTS A total of 330 patients who underwent totally thoracoscopic mitral replacement via two port or three port from January 1, 2016 to December 31, 2017 were enrolled (two-port group: n=103; three-port group: n=227). Propensity score matching resulted in 71 matched pairs with improved balance post matching in baseline covariates. The baseline differences between two groups were eliminated (P>0.05 for all baseline variables). The cardiopulmonary bypass time (min) (154.27±57.02 vs. 142.68±51.33 P=0.183) and the aortic cross-clamp time (min) (106.99±106.98 vs. 90.16±31.63 P=0.206) in the two-port group were not significantly different from those in the three-port group. No significant difference was observed between the two groups in mechanical ventilation time, duration of intensive care unit stay, or amount of postoperative chest drainage. No perioperative death or re-exploration for bleeding was found in either group. As for other postoperative complications, two groups had the similar rate of lung infection lung infection (1.41% vs. 1.33% P=1.000) or acute renal failure (1.41% vs. 1.41% P=1.000). CONCLUSIONS No significant differences in cardiopulmonary bypass time, aortic cross-clamp time, overall operative time, perioperative mortality, or complications were observed between two-port and three-port totally thoracoscopic mitral valve replacement. Two-port totally thoracoscopic mitral valve replacement is a safe, effective, and feasible procedure for mitral valve replacement.

Abstract
OBJECTIVE To explore the role of KCNMA1-AS1 in epithelial ovarian cancer (EOC) and its underlying mechanism. PATIENTS AND METHODS We first screened out the differentially expressed lncRNAs (KCNMA1-AS1) in the GEO (gene expression omnibus) database. The relationship between KCNMA1-AS1 expression and prognosis of EOC with different pathological types was analyzed by meta-analysis. Subsequently, KCNMA1-AS1 expressions in EOC tissues and normal ovarian tissues were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between KCNMA1-AS1 level with progression-free survival (PFS) and overall survival (OS) of EOC was analyzed. Furthermore, proliferation and migration of EOC cells transfected with the corresponding plasmids were analyzed by Cell Counting Kit-8 (CCK-8) and transwell assay, respectively. Apoptosis-related genes in EOC cells were detected by Western blot. RESULTS KCNMA1-AS1 was a risk factor for prognosis in high-grade, advanced and serous EOC. Upregulated KCNMA1-AS1 was found in EOC tissues than that of normal tissues, showing the diagnostic potential of KCNMA1-AS1 in EOC. Statistical analysis indicated that KCNMA1-AS1 was not correlated with the DFS, OS, age, histological type, lymph node metastasis and recurrence, but related to FIGO stage of EOC patients. For in vitro experiments, the proliferation and migration of were enhanced, and apoptosis of HO8910 cells overexpressing KCNMA1-AS1 was inhibited. Furthermore, elevated expressions of Caspase-3 and Caspase-9, as well as reduced expression of Bcl-xL, were observed after KCNMA1-AS1 knockdown in EOC cells. CONCLUSIONS KCNMA1-AS1 is overexpressed in EOC and negatively correlated with its prognosis. KCNMA1-AS1 participates in the occurrence and development of EOC by promoting proliferation, migration and inhibiting apoptosis of ovarian cancer cells via apoptosis pathway.

Abstract
Water buffalo (Bubalus bubalis) is of great economic importance as a provider of milk and meat in many countries. However, the milk yield of buffalo is much lower than that of Holstein cows. Selection of candidate genes related to milk production traits can be applied to improve buffalo milk performance. A systematic review of studies of these candidate genes will be greatly beneficial for researchers to timely and efficiently understand the research development of molecular markers for buffalo milk production traits. Here, we identified and classified the candidate genes associated with buffalo milk production traits. A total of 517 candidate genes have been identified as being associated with milk performance in different buffalo breeds. Nineteen candidate genes containing 47 mutation sites have been identified using the candidate gene approach. In addition, 499 candidate genes have been identified in six genome-wide association studies (GWASes) including two studies performed with the bovine SNP chip and four studies with the buffalo SNP chip. Genes CTNND2 (catenin delta 2), APOB (apolipoprotein B), FHIT (fragile histidine triad) and ESRRG (estrogen related receptor gamma) were identified in at least two GWASes. These four genes, especially APOB, deserve further study to explore regulatory roles in buffalo milk production. With growth in the number of buffalo genomic studies, more candidate genes associated with buffalo milk production traits will be identified. Therefore, future studies, such as those investigating gene location and functional analyses, are necessary to facilitate the exploitation of genetic potential and the improvement of buffalo milk performance.

Abstract
Objective: To investigate the clinicopathologic features and prognosis of gastrointestinal mantle cell lymphoma (GI-MCL). Methods: Clinical data of 38 GI-MCL patients diagnosed at Beijing Friendship Hospital from January 2002 to January 2016 were retrospectively reviewed morphologically and immunophenotypically. IgH/CCND1 gene fusion was assessed by fluorescent in situ hybridization (FISH). For comparison, 60 cases of non-GI-MCL were randomly selected to extract the differences inclinicopathological features and patient survival between the two groups. Results: Of 38 patients with GI-MCL, the median age was 62 years (range: 35-78 years, 23 males and 15 females), of which patients of 60 years of age or older accounted for 55.3%. Patients with clinical course of less than 6 months accounted for 81.1%(30/37). The main symptoms included abdominal pain, diarrhea, anorexia and hematochezia. Those with B symptoms accounted for 32.4%(12/37). The tumor most often involved lleocecal region (57.9%, 22/38), followed by rectum (36.8%, 14/38) and sigmoid colon (28.9%, 11/37), and the stomach accounted for 18.4%(14/38). Endoscopic polypoid lesions were found in 33 cases (86.8%, 33/38), of which 22 cases (66.7%, 22/33) were multiple. Five cases (13.2%, 5/38) presented with local protuberant neoplasm. According to Ann Arbor staging, 3 cases (7.9%, 3/38) were at stage Ⅰ, 4 cases (10.5%, 4/38) were at stage Ⅱ, and 31 cases (81.6%, 31/38) were at stage Ⅳ. The number of patients with tumor involvement of abdominal and retroperitoneal lymph nodes accounted for 45.7%(16/35), including 41.7%(15/36) involving the superficial lymph node, 17.1%(6/35) involving extranodal sites, and 23.5%(8/34) having splenomegaly. All of the 38 cases were classic MCL, and the tumor was composed of uniform lymphoid cells and effacing normal mucosal structure. All tumors were positive for CD20 and CD5. 97.4% (37/38) tumors were positive for cyclin D1, and 92.0% (23/25) tumors were positive for SOX11. FISH test was positive in 1 case of cyclin D1 negative tumor. Twenty-eight patients (73.7%) had a median follow-up of 25.0 months (range: 3-79 months). The 3-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ of patients were 80.0% and 69.1%, respectively (P> 0.05). The 3-year survival rate for GI-MCL and non-GI-MCL patients were 71.7% and 72.5%, respectively (P>0.05). Single factor analysis showed that age of >60 years and splenomegaly were correlated with a worse overall survival rate (P<0.05). Conclusions: Gastrointestinal malaise is the most common presenting symptom in GI-MCL patients. GI-MCL more commonly involves colorectum with more frequent multiple polypoid lesions. Patients of age >60 years and with splenomegaly have poor prognosis. There is no difference in the prognosis between GI-MCL and non-GI-MCL patients.

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 investigate clinicopathologic features and prognostic factors of mantle cell lymphoma(MCL). Methods: The clinical data of 349 MCL patients diagnosed at Beijing Friendship Hospital from January 2004 to January 2016 were retrospectively collected. Corresponding histological sections were reviewed. Additional studies included immunohistochemical staining using the MaxVision two-step method, IgH/CCND1 fusion gene detection by fluorescent in situ hybridization (FISH), and correlative statistical analysis. Results: Of 349 patients with MCL, the median patient age was 61 years (range: 25-83 years, M∶F=2.7∶1.0) and the age of 243 patients ranged from 51 to 70 years (69.6%). Those with B symptoms accounted for 22.4% (70/313). Most of the patients presented with superficial lymphadenopathy and the clinical stage Ⅲ-Ⅳ accounted for 76.1% (235/309). Extranodal involvement was seen in 47.9% (148/309), among which the gastrointestinal tract accounted for 31.8% (47/148) and splenic involvement accounted for 15.4% (47/305). Three hundred and nine (88.5%) cases were of classical type and 40 (11.5%) cases were of aggressive variant type, and all were composed of proliferating lymphoid cells. All the tumors were positive for CD20 and cyclin D1, and 98.6% (344/349) tumors were weakly positive or positive for CD5. FISH test was positive in 12 cases that were CD5 negative and with cyclin D1 partial expression.Two hundred and forty-three (69.6%) patients had a median follow-up of 26 months (range: 3-108 months). The 3- and 5-year overall survival rates for patients were 63.0% and 34.8%, respectively. Single factor analysis showed that age of >60 years, splenic involvement, aggressive variant type, incompletely overlapping type [Based on the degree of overlap ≥90% and <90% between the follicular dendritic cell (FDC) meshwork and tumor cells, the tumors were divided into the completely overlapped type and incompletely overlapped type] and Ki-67 index >40% had poor prognosis (P<0.05). Multiple factor Cox proportional risk regression analysis after removing the aggressive variant type showed that age, splenic involvement, the degree of overlap between the FDC meshwork and tumor cells and Ki-67 index were independent prognostic factors for overall survival rate of MCL patients (P<0.05). Conclusions: MCL is more commonly found among middle-aged and elderly men. Patient age, splenic involvement, degree of overlap between FDC meshwork and tumor cells and Ki-67 index are the independent prognostic indicators for MCL.

Abstract
RNA interference (RNAi) is a very effective technique for studying gene function and may be an efficient method for controlling pests. Trehalose-6-phosphate synthase (TPS), which plays a key role in the synthesis of trehalose and insect development, was cloned in Tribolium castaneum (Herbst) (TcTPS) and the putative functions were studied using RNAi via the injection of double-stranded RNA (dsRNA) corresponding to conserved TPS and trehalose-6-phosphate phosphatase domains. Expression analyses show that TcTPS is expressed higher in the fat body, while quantitative real-time polymerase chain reaction results show that the expression of four trehalase isoforms was significantly suppressed by dsTPS injection. Additionally, the expression of six chitin synthesis-related genes, such as hexokinase 2 and glutamine-fructose-6-phosphate aminotransferase, was suppressed at 48 and 72 h post-dsTPS-1 and dsTPS-2 RNA injection, which were two dsTPS fragments that had been designed for two different locations in TcTPS open reading frame, and that trehalose content and trehalase 1 activity decreased significantly at 72 h post-dsRNA injection. Furthermore, T. castaneum injected with dsTPS-1 and dsTPS-2 RNA displayed significantly lower levels of chitin and could not complete the molting process from larvae to pupae, revealing abnormal molting phenotypes. These results demonstrate that silencing TPS gene leads to molting deformities and high mortality rates via regulation of gene expression in the chitin biosynthetic pathway, and may be a promising approach for pest control in the future.

Abstract
microRNA-1 (miR-1) is a well-studied conservative microRNA (miRNA) involved in immune responses in mammals and insects. However, little is known about its role in pesticide resistance in arthropods. In this study, we found that a microRNA belong to miR-1 family (tci-miR-1-3p) was significantly down-regulated in a cyflumetofen-resistant strain (CYR) of Tetranychus cinnabarinus compared with its homologous susceptible strain (SS), indicating an involvement of miR-1 in cyflumetofen resistance in mites. One glutathione S-transferase (GST) gene (TCGSTM4, a mu class GST gene), a candidate target gene of tci-miR-1-3p, was found to be significantly down-regulated when tci-miR-1-3p was over-expressed. The specific interaction between tci-miR-1-3p and the target sequence in the 3' untranslated region of TCGSTM4 was confirmed. A decrease or increase in tci-miR-1-3p abundance through feeding miRNA inhibitors or mimics significantly increased or decreased TCGSTM4 expressions at the mRNA and protein levels, respectively. In addition, an over-expression of tci-miR-1-3p resulted in a decrease in the tolerance of T. cinnabarinus to cyflumetofen in both SS and CYR strains, and vice versa. After decreasing TCGSTM4 transcription via RNA interference, T. cinnabarinus became more sensitive to cyflumetofen in both resistant and susceptible mites, and the change in mortality was greater in CYR than that in SS. Moreover, the recombinant TCGSTM4 could significantly decompose cyflumetofen, indicating that TCGSTM4 is a functional gene responsible for cyflumetofen resistance in mites.

Abstract
Objective: To analyze clinical, pathological, molecular and genetic characteristics of Burkitt-like lymphoma with chromosome 11q aberration. Methods: A case of Burkitt-like lymphoma with 11q aberration was presented at Beijing Friendship Hospital in November 2016 with detailed clinicopathological features, immunophenotypes, Epstein-Barr virus(EBV) status and molecular genetic characteristics. Results: The patient was a 38-year-old man presenting with the cervical lymphadenopathy. In morphology, the tumor had the similar characteristics of Burkitt lymphoma, including diffuse infiltration of medium to large lymphoid cells, and presence of"starry sky"phenomenon. Immunophenotypically, the tumor cells were positive for CD20, CD10, bcl-6, but negative for bcl-2. MUM-1 showed weak and patchy positivity. Ki-67 index was more than 95%. C-MYC expression was seen in about 50% of tumor cells. EBV in situ hybridization was negative. IgH and IgK genes were clonally rearranged.Fluorescence in situ hybrization detection using MYC break probe was negative but ATM gene amplification on chromosome 11q was detected. The patient did not receive any chemotherapy or radiotherapy and had not recurrence during the 10 months follow-up. Conclusion: Burkitt-like lymphoma with chromosome 11q aberration has similar clinical, morphological and immunological characteristics to classic Burkitt's lymphoma.

Abstract
Objective: To investigate clinicopathological features and prognosis of tonsillar mantle cell lymphoma(TMCL). Methods: Clinical data of 25 patients with TMCL at Beijing Friendship Hospital, Capital Medical University from 2002 to 2016 were included. All the cases were reviewed microscopically. Various immunohistochemical stains were performed using the MaxVision two-step method. IgH/CCND1 gene fusion was detected by fluorescent in situ hybridization(FISH). Additionally, randomly selected 40 cases of non-tonsil MCL of the same period were compared. Results: Among all mantle cell lymphomas (MCL), TMCL accounted for 5.6%(25/449). The median age of the patients was 60 years(range: 44-82 years) with a M∶F ratio of 5.3 to 1.0. The main symptoms were sore throat and foreign body sensation and patients usually presented with enlargement or mass of tonsil. At the early stage of the disease, 18 cases(72.0%) were clinically misdiagnosed as tonsillitis. Lymph node involvement was present in 76.0%(19/25) of the patients. There were 4 cases(16.0%)with current splenic involvement, 11 cases(44.0%) with pharyngeal focal recidivism, and 3 cases(12.0%) with involvement of other non-lymphoid organs. Morphologically, tonsillar architectures were effaced at various degrees. Eighteen MCL cases showed classical type and 7 cases were blastoid variant. All tumors were positive for CD20 and cyclin D1. 92.0%(23/25) tumors showed weakly positive or positive expression for CD5. FISH test that IgH/CCND1 gene fusion was positive in two CD5 negative classical cases. 18 patients(72.0%) had a median follow-up time of 26 months(range: 6-81 months). The difference of survival rate between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients was not statistically significant(P>0.05). Compared with NTMCL, TMCL was found to have higher proportion of stage Ⅰ-Ⅱ disease (χ(2)=12.789, P<0.01), lower the proportion of non-lymphatic organ involvement (χ(2)=8.125, P<0.01), and better prognosis (χ(2)=4.351, P=0.037). Conclusion: The incidence of TMCL is low and prone to be misdiagnosed as tonsillitis. Patients with TMCL are more likely at stage Ⅰ-Ⅱ at presentation and the prognosis is better than that of NTMCL.

Abstract
Asymmetric synthesis of chiral β-hydroxy esters, the key building blocks for many functional materials, is currently of great interest. In this study, the biocatalytic anti-Prelog reduction of methyl acetoacetate (MAA) to methyl-(R)-3-hydroxybutyrate ((R)-HBME) was successfully carried out with high enantioselectivity using the whole cell of engineered E. coli, which harbored an AcCR (carbonyl reductase) gene from Acetobacter sp. CCTCC M209061 and a GDH (glucose dehydrogenase) gene from Bacillus subtilis 168 for the in situ regeneration of the coenzyme. Compared with the corresponding wild strain, the engineered E. coli cells were proved to be more effective for the bio-reduction of MAA, and afforded much higher productivity. Under the optimized conditions, the product e.e. was >99.9% and the maximum yield was 85.3% after a reaction time of 10 h, which were much higher than those reported previously. In addition, the production of (R)-HBME increased significantly by using a fed-batch strategy of tuning pH, with a space-time yield of approximately 265 g L-1 d-1, thus the issue in previous research of relatively low substrate concentrations appears to be solved. Besides, the established bio-catalytic system was proved to be feasible up to a 150 mL scale with a large-scale relatively high substrate concentration and selectivity. For further industrial application, these results open a way to use of whole cells of engineered E. coli for challenging higher substrate concentrations of β-ketone esters enantioselective reduction reactions.

Abstract
One avian leukosis virus subgroup J (ALV-J) strain was isolated from 67 commercial live poultry vaccines produced by various manufacturers during 2013-2016 in China. The complete genomes of the isolate were sequenced and it was found that the genes gag and pol of the strain were relatively conservative, while the gp85 gene of the strain GX14YYA1 had the highest similarities with a field strain GX14ZS14, which was isolated from the chickens of a farm that had once used the same vaccine as the one found to be contaminated with the GX14YYA1. This is the first report of ALV-J contaminant in live poultry vaccine in China. Our finding demonstrates that vaccination of the commercial live vaccines might be a potential new route for ALV-J transmission in chickens and highlights the need for more extensive monitoring of the commercial live vaccines in China.

Abstract
Objective: To investigate the clinicopathologic characteristics of neoplastic cell-rich mixed cellularity classical Hodgkin lymphoma(MCCHL-R) and to compare the prognosis with typical mixed cellularity classic Hodgkin lymphoma(MCCHL). Methods: Fifty-four patients with MCCHL-R(the tumor cells >10%) and 65 patients with typical MCCHL identified from 1 721 Hodgkin lymphomas were reviewed to compare the clinicopathological characteristics including morphologic and immunophenotypic features, EBV infection status, clinical therapy and overall survival. Results: The median age of the patients of MCCHL-R was 28.5 years(range: 9-76 years, male∶female=1.6∶1.0). Twenty-seven patients(50.0%) had B symptoms. Most patients had cervical lymph node involvement(81.5%, 44/54). Mediastinum and spleen involvement were seen in 69.2%(36/54) and 24.1%(13/54), respectively. Extranodal non-lymphoid organ involvement was seen in 41.3%(19/46) cases. Morphologically, lymph node architectures were effaced at various degree with large neoplastic cells of variable morphology, including Hodgkin/Reed-Sternberg(H/RS) cells and anaplastic large cells. There were abundant background heterogeneous admixtures of non-neoplastic inflammatory and accessory cells that were predominant mature small lymphocytes. All tumors were positive for CD30 and weakly positive for PAX5. Epstein-Barr encoded RNA(EBER)detectable by in situ hybridization was seen in 39.0% cases. Forty-six patients had a median follow-up time of 32.5 months(range: 5-128 months) and the 5-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients were 91.7% and 50.1%, respectively(P<0.05). The 5-year survival rate for MCCHL-R was lower than typical MCCHL patients. Single factor analysis showed that age of >45 years, extranodal involvement and stage Ⅲ-Ⅳ were correlated with poorer 5-year survival rate(P<0.05). Multiple factors Cox proportional hazards regression showed that extranodal involvement was the independent prognostic factor(RR: 4.352, 95%CI: 1.122-16.879, P<0.05). Conclusions: MCCHL-R is more common in young people. The tumor has pathological features of classic Hodgkin lymphoma enriched with the tumor cells(>10%) and similar immunophenotype to classical Hodgkin lymphoma. Compared with typical MCCHL, extranodal disease is an independent prognostic factor of MCCHL-R.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. Histone deacetylase 6 (HDAC6) is frequently altered in DLBCL and inhibition of HDAC6 has potent anti-tumor effects in vitro and in vivo. We profiled miRNAs that altered in the HDAC6 knockdown DLBCL cells with NanoString nCounter assay and identified microRNA-27b (miR-27b) as the most significantly increased miRNA. We validated decreased expression of miR-27b in DLBCL tissues, and we found that low expression of miR-27b was associated with poor overall survival of patients with DLBCL. In addition, forced expression of miR-27b suppressed DLBCL cell viability and proliferation in vitro, and inhibited tumor growth in vivo. Mechanistically, Rel A/p65 is found to negatively regulate miR-27b expression, and its acetylation and block of nuclear translocalization caused by HDAC6 inhibition significantly elevates miR-27b expression. Furthermore, miR-27b targets MET and thus represses the MET/PI3K/AKT pathway. These findings highlight an important role of miR-27b in the development of DLBCL and uncover a HDAC6-Rel A/p65-miR-27b-MET signaling pathway. Elevating miR-27b through HDAC6 inhibition would be a promising strategy for DLBCL treatment.

Abstract
Objective: To investigate the pathological types and prognostic factors of primary lymphoma of breast (PLB). Methods: The clinical pathological data of 115 cases of PLB during October 2006 to October 2016 were retrospectively analyzed, and the basic clinical and pathological data, pathology types and the immunohistochemical slides by EliVision two-step method for staining were summarized. Results: Almost all the patients were women (113/115), and the median age was 52 years old (range: 27 to 81 years old). The main symptom was painless progressive mass in breast. Ten cases (8.7%) showed B symptoms. The masses were mainly confined to the unilateral breast (80.9%, 93/115), of which 22 cases showed axillary lymph nodes enlargement in the same side. The average diameter of masses was 3.0 cm (range from 0.5 to 9.0 cm). There is no differences between the sides (left or right). Pathologically, 106 cases (92.2%) were mature non-Hodgkin's B-cell lymphomas, of which there were mainly diffuse large B cell lymphoma (DLBCL, 64.3%) and mucosa associated lymphoid tissue (MALT) extranodal marginal lymphoma (17.4%). Five cases (4.4%) were mature T/NK cell lymphomas, including extranodal nasal NK/T cell lymphoma (1.7%), peripheral T-cell lymphoma non-specific type (0.9%), subcutaneous panniculitis-like T cells lymphoma (0.9%) and undivided (0.9%). Four cases were lymphoblastic lymphoma. According to Ann Arbor staging criteria, 93 cases were stage ⅠE (6 cases were stage ⅠEB), 22 cases were stage ⅡE (4 cases were stage ⅡEB). Ninety-two cases were followed 1 to 122 months (median: 36 months). The five-year overall survival rate was 85.3%, and 13 patients dead. B symptom was one of the factors that affect the prognosis (P<0.05), but the pathological type has no relationship with the prognosis (P>0.05). Conclusions: PLB is relatively rare, the main clinical manifestation is painless mass, which is difficult to distinguish with breast carcinoma. The most common type is DLBCL, followed by MALT lymphoma, while T cell lymphoma is rarely seen. PLB is early stage tumor with good prognosis, while patients with B symptom turn out to suffer worse prognosis.
