Abstract
Microbial remediation of oil-contaminated groundwater is often limited by the low temperature and lack of nutrients in the groundwater environment, resulting in low degradation efficiency and a short duration of effectiveness. In order to overcome this problem, an immobilized composite microbial material and two types of slow release agents (SRA) were creatively prepared. Three oil-degrading bacteria, Serratia marcescens X, Serratia sp. BZ-L I1 and Klebsiella pneumoniae M3, were isolated from oil-contaminated groundwater, enriched and compounded, after which the biodegradation rate of the Venezuelan crude oil and diesel in groundwater at 15 °C reached 63 % and 79 %, respectively. The composite microbial agent was immobilized on a mixed material of silver nitrate-modified zeolite and activated carbon with a mass ratio of 1:5, which achieved excellent oil adsorption and water permeability performance. The slow release processes of spherical and tablet SRAs (SSRA, TSRA) all fit well with the Korsmeyer-Peppas kinetic model, and the nitrogen release mechanism of SSRA N2 followed Fick's law of diffusion. The highest oil removal rates by the immobilized microbial material combined with SSRA N2 and oxygen SRA reached 94.9 % (sand column experiment) and 75.1 % (sand tank experiment) during the 45 days of remediation. Moreover, the addition of SRAs promoted the growth of oil-degrading bacteria based on microbial community analysis. This study demonstrates the effectiveness of using immobilized microbial material combined with SRAs to achieve a high efficiency and long-term microbial remediation of oil contaminated shallow groundwater.

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
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
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
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
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).

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
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 clarify the morbidity and risk factors of allergic rhinitis (AR) in China so as to provide scientific basis for prevention of AR in the relevant populations.Method:Pubmed,Embase,Web of science,Cochrane Library,CNKI,VIP,Wanfang Data,CBM databases were searched for associated studies. The prevalence and risk factors of AR in China were retrieved from individual studies and the pooled estimates generated by R3.2.3 software.Result:Thirty-one cross-sectional studies were included in the Meta-analysis. The results indicated that the incidences of AR in Chinese children were 15.79%(95%CI 15.13-16.45).The highest prevalence is 17.20% in central China,the lowest is 13.94% in eastern China. The incidences of AR in Chinese adult were 13.26% (95%CI 12.05-14.47).The highest prevalence is 15.45% in southern China,the lowest is 10.93% in southwestern China. The pooled odds ratio (OR) values of family history (5.40),dust exposure history (2.04),drug allergy history (2.83),history of asthma(4.45),environmental tobacco smoking(ETS)(2.00),water damage (1.50),upholstering(1.41),pollen allergy(17.18),molds(1.31),keeping pets (1.29),cockroach (1.69).Conclusion:A study on the epidemic tendency of AR in China showed the morbidity of AR in Chinese children is higher than adult. Moreover,prevalence vary from region to region. Eleven kinds of risk factors mentioned above play imperative roles in the pathogenesis of AR. The early interventions which are associated with risk factors should be implemented in AR.

However, lager scaled reports concerned on the co-morbidity of this two diseases in children are rare. In this meta-analysis, we aim to clarify the morbidity of asthma in children with AR.Method:Pubmed, Science, Springer, Elsevier, Embase, BMJ Journals, Wanfang data, VIP, CBM and CNKI were searched for relevant studies.The prevalences of asthma in children with AR were retrieved from individual studies and the pooled estimates generated by R3.2.3.Result:Fifteen cross-sectional studies were included in the meta-analysis. The results showed that the incidences of asthma in AR children were 35.01%(95%CI32.32%-37.70%) in China and 31.59%(95%CI28.02%-35.16%) in foreign countries.Conclusion:Comorbidity of AR and asthma was high in children. The incidence of asthma is higher in children with AR in China than that in foreign countries.

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.

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

Abstract
OBJECTIVE This study was designed to investigate the influence of several polymorphisms in neuronal NOS genes and apolipoprotein AI on the hormone-related osteonecrosis of the femoral head (ONFH) risk. PATIENTS AND METHODS Peripheral blood mononuclear cell (PBMCs) samples extracted from hormone-related ONFH patients and controls were used to amplify fragments of the apolipoprotein A1 and neuronal NOS exon 7 and intron 4 using specific PCR primers. The products were analyzed by DNA sequencing and mapped to find the genotype distributions. RESULTS The proportions of G/G, G/T and T/T on NOS exon 7 in hormone-related ONFH patient group and control group were 68%, 27%, 5% and 81%, 16%, and 3% respectively. The proportions of G/T and T/T in the experimental group were significantly higher than those in the control group (p<0.05). The proportions of b/b, a/b and a/a on NOS intron 4 in hormone-related ONFH patient group and control group were 85%, 13%, 1% and 96%, 5% and 0% respectively. The proportion of a/b in the experimental group was much higher than in the control group. The distribution of A/A, G/A and G/G in the apolipoprotein gene in control and experimental groups were 19%, 33%, 71% and 42%, 20%, 38% respectively. In this case, the experimental group's A/A genotype was significantly higher than the control's genotype. CONCLUSIONS In our study group, several polymorphisms of the neuronal NOS gene and apolipoprotein A1 genes were significantly associated with hormone-related ONFH. These results suggest that those gene polymorphisms might be involved in the occurrence and development of ONFH.

Abstract
Early recovery of myocardial perfusion is beneficial for myocardial ischemia. However, ischemia-reperfusion (I/R) may exacerbate myocardial injury. Research shows that total peony glucoside (TPG) can inhibit ischemic myocardial cell apoptosis. However, whether it can ameliorate I/R injury remains poorly understood. This study explored the effect of TPG pretreatment on I/R, through nuclear factor-kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) expressions in I/R-affected myocardium. Healthy 7-week-old male Sprague Dawley rats were randomly categorized into sham operation (A), modeling (B), and 100, 200, and 400 mg/kg TPG pretreatment groups (C, D, and E, respectively), with 20 rats in each group. I/R rat models were designed by ligating left anterior descending coronary artery for 30 min to induce ischemia and for 120 min to induce reperfusion. Serum interleukin 6 (IL-6) and interleukin 8 (IL-8) levels were measured using enzyme linked immunosorbent assay. NF-κB and ICAM-1 mRNA and protein expressions were detected through RT-PCR and western blot analysis, respectively. Compared to group A, serum IL-6 and IL-8 levels of group B elevated significantly (P < 0.05), whereas NF-κB and ICAM-1 mRNA and protein expressions increased in the myocardium (P < 0.05). Serum IL-6 and IL-8 levels, and NF-κB and ICAM-1 mRNA and protein expressions, in myocardium of TPG groups reduced in a dose-dependent manner. Therefore, TPG pretreatment could alleviate myocardium reperfusion injury in I/R rat models by reducing NF-κB and ICAM-1 mRNA and protein expressions and cytokine secretions. This mechanism could be associated with the inhibition of NF-κB activation and downregulation of ICAM-1 expression.

Abstract
OBJECTIVE We evaluated uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP) levels in different clinical types of acute coronary syndromes (ACS) and in relationship with the severity of coronary artery lesions. Furthermore, we explored its clinical significance. PATIENTS AND METHODS From June 2013 to January 2015, we studied patients in their first onset of symptoms and hospitalization for coronary angiography. According to coronary angiography results, we divided patients into two groups: 93 patients with ACS and 30 patients with normal coronary arteries as the control group. ACS patients were divided further into three subgroups: patients with ST-segment elevation myocardial infarction (STEMI) (n=34); patients with non-ST segment elevation myocardial infarction (NSTEMI) (n=29); and patients with unstable angina (n=30). According to their Gensini scores, patients were divided into mild, moderate and severe groups. We compared UA and hs-CRP levels and the relationship with Gensini scores between different groups. RESULTS UA and hs-CRP levels in the ACS group were higher than those in the control group (p < 0.05). UA and hs-CRP levels in the STEMI group were higher than those in the NSTEMI, unstable angina and control groups (p < 0.05). UA and hs-CRP levels in the NSTEMI patients were higher than those in the unstable angina and control groups (p < 0.05). UA and hs-CRP levels in the unstable angina patients were higher than those in the control group (p < 0.05). hs-CRP levels in the STEMI patients were higher than the other groups (p < 0.05). hs-CRP levels in the NSTEMI patients were higher than the unstable angina and the control groups (p < 0.05) while hs-CRP levels in the unstable angina patients were higher than the control group (p < 0.05). Additionally, according to the Gensini score group, we discovered that ACS patients in the severe group had higher hs-CRP levels than the other three groups (p < 0.05) while the moderate group had higher levels than the other two groups (p < 0.05). The mild group had higher levels than the control group (p < 0.05). Correlation analysis suggested that UA levels and Gensini scores had a positive correlation (p < 0.05). hs-CRP levels and Gensini scores also showed a positive correlation (p < 0.05). CONCLUSIONS UA and hs-CRP levels should be considered as factors to use in the risk stratification in ACS patients.

Abstract
OBJECTIVE To evaluate the clinical, radiological and pathological features of primary or metastatic malignancies presenting with multiple lung cavities. METHODS A total of 38 cases met the inclusion criteria and had adequate imaging data for retrospective review between June 2006 and August 2013. There were 30 cases of primary lung cancer, and 8 cases of pulmonary metastasis including 6 gastrointestinal tract malignancies, 1 vulva malignancy and 1 scalp malignancy. There were 21 females and 17 males, with a median age of 63 years. RESULTS Cough and expectoration were the most common clinical manifestations of primary lung cancer(22/30). There were 4 main types of lung cavities, including thick-walled cavities(n=12), circular cavities (n=24), thin-walled cavities or cystic cavities (n=11), cavities or multi-cystic changes within airspace consolidation or ground glass opacity(n=11). The cavitary lesions were often accompanied by pulmonary nodules, mass and ground glass opacity(32/38, 84%). The presence of internal soft-tissue septa in the cavity was commonly seen(17/38, 45%). The 4(th) type of cavity and presence of air-fluid levels were only found in lung adenocarcinoma, including 5 cases of mucinous adenocarcinoma. In both primary lung cancers and metastatic tumors, adenocarcinoma was the most common histological type (29/30 and 6/8, respectively). The other histological types included 1 case of lung squamous cell carcinoma, 1 vulva adenosquamous carcinoma and 1 scalp angiosarcoma. The possible mechanisms of cavity formation included necrosis, mucin-secretion air-containing cystic spaces in papillary tumors and the check-valve mechanism. CONCLUSIONS Adenocarcinoma was the most common histological type in multiple cavitary primary lung cancers and metastatic tumors. These cavities showed varied radiological features and were easy to be misdiagnosed as benign cavitary lung diseases.

Abstract
OBJECTIVE To explore clinical effects of Tirofiban treatment on patients with high-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS) after percutaneous coronary intervention (PCI). PATIENTS AND METHODS 107 patients with high-risk NSTE-ACS after PCI were selected and were divided into two groups. One group of 56 patients was treated with Tirofiban and a second group of 51 patients was taken as control. The occurrence conditions of creatine kinase-myoglobin (CK-MB), cardiac troponin1 (cTnI) level, hemorrhage incidents and major adverse cardiac events (MACE) incidents after treatments were compared. RESULTS After 24 h operation, CK-MB and cTnI level in Tirofiban group were both significantly lower than those in control group (p < 0.05), while the difference of hemorrhage incidents between two groups is of no statistical significance (p < 0.05); and the differences in overall occurrence rate of MACE incidents and the occurrence rate of angina pectoris after infarct between two groups were statistically significant (p < 0.05). CONCLUSIONS Tirofiban could improve the blood supply condition of hearts of patients with high-risk NSTE-ACS after emergent PCI, lower the occurrence rate of MACE incidents, and decrease the risk of hemorrhage.

Abstract
OBJECTIVE To investigate the differences of the B-type natriuretic peptide (BNP) levels in serum or plasma of the STEMI patients with different infarction sites. To explore the relationship between the BNP level and the short-term prognosis in patients with ST-segment elevation myocardial infarction (STEMI). PATIENTS AND METHODS A total of 216 STEMI patients were enrolled in this study from June 2012 to June 2014. All patients received coronary angiography (CAG). Based on electrocardiography (ECG) and CAG results, patients were divided into three groups. Group A included 80 patients with anterior/lateral wall myocardial infarction, group B included 76 patients with inferior/posterior wall myocardial infarction and group C included 60 patients with right ventricular myocardial infarction. We enrolled 53 patients with normal CAG results as Group D. BNP levels were compared among these groups. and according to BNP levels, all patients were subdivided into normal BNP group (< 100 ng/mL, n = 53), mild-higher BNP group (100-400 ng/mL, n = 105) and marked-higher BNP group (≥ 400 ng/mL, n = 58). The occurrence of major adverse cardiovascular events (MACE) including secondary heart failure, severe arrhythmia, post-infarction angina, recurrent myocardial infarction, and cardiac death within 6 months after disease onset were assessed. RESULTS BNP levels showed a gradually decreasing trend in groups A, B, C and D (p < 0.05). Significant differences in left ventricular ejection fraction (LVEF) were found among normal BNP group, mild-high BNP group and marked-higher BNP group (p < 0.05). The MACE occurrence presented no statistical differences between normal BNP group and mild-higher BNP group (p > 0.05). The MACE prevalence in marked-higher BNP group was significantly higher than normal BNP group and mild-higher BNP group (p < 0.05). CONCLUSIONS BNP levels can be used as a clinical indicator to predict short-term prognosis in STEMI patients.

Abstract
The aim of this study was to investigate the expression of AIB1 in human esophageal squamous cell carcinoma and its correlation with Ki67 expression. The immunohistochemical method streptavidin-perosidase was used to analyze the expression of AIB1 and Ki67 in specimens from 60 patients with esophageal squamous cell carcinoma and in 20 control individuals with normal esophageal tissue. Expression correlation, clinical significance, and relationships between the two groups were determined. In the 20 individuals with normal esophageal mucosa cells, AIB expression was primarily detected at low levels in the nucleus or not at all, whereas 41.6% of specimens from individuals with esophageal squamous cell carcinoma exhibited high levels of AIB1 expression (P < 0.05). Furthermore, overexpression of AIB1 was observed more frequently in carcinoma specimens with late T stages (T3/ T4) and lymph node metastases (P < 0.05). No significant differences were observed in AIB1 expression by gender, age, or pathological type (P < 0.05). Comparatively, the rate of positive expression of Ki67 In esophageal squamous cell carcinoma specimens was 65.0% (39/60) (P < 0.05). Of these, 29 specimens exhibited simultaneous expression of AIB1, 25 of which demonstrated AIB1 overexpression; expression of AIB1 and Ki67 was positively correlated (P < 0.01). In summary, the results from this study suggested that AIB1 protein expression was associated with the T stage and lymph node metastasis in esophageal squamous cell carcinoma, and that Ki67 might play a role in the AIB1 non-steroid receptor pathway.

Abstract
This retrospective study aimed to observe the cura-tive effect and adverse reactions of three-dimensional conformal radiotherapy combined with topotecan chemotherapy in patients with platinum-resistant recurrent epithelial ovarian carcinoma. The chemoradiotherapy group (N = 22) received 15 mv X-rays with 1.8 to 2.0 Gy/f/d radiation, 5 times per week. The total dose was 45 to 65 Gy; the median dose was 52.5 Gy. Topotecan chemotherapy (2.0 mg/m(2)) was administered after the first week of radiotherapy on days 1, 8, and 15; it was repeated every 28 days. The only che-motherapy group (N = 20) received topotecan chemotherapy (4.0 mg/m(2)) in the first week, and the dose was administered on days 1, 8, and 15; it was repeated every 28 days. The median follow-up times were 18.5 months (2 to 37.7) and 10.8 months (1.5 to 29.6) in the chemoradiotherapy and in the only chemotherapy groups, respectively. The total response rates were 42.1% (8/19) and 11.1% (2/18), respectively. The clinical benefit rates were 68.4% (13/19) and 22.2% (4/18), respectively, with significant difference (P < 0.05). The median disease progression-free periods were 9.8 and 6.6 months, respectively, with significant difference (P < 0.001). The median survival times were 19.7 and 12.5 months, respective-ly, with significant difference (P < 0.05). The degrees of digestive tract reaction rates were 26.3% (5/19) and 16.7% (3/18), whereas the hematology toxicity rates were 21.1% (4/19) and 22.2% (4/18), respectively, with no significant difference (P > 0.05). As three-dimensional conformal radiotherapy combined with topotecan che-motherapy had good curative effect on platinum-resistant recurrent epithelial ovarian cancer, with mild adverse reactions, this tech-nique can be used as a remedial measure.

Abstract
OBJECTIVE To study the appropriate surgical procedure for Stage I endometrial carcinoma (EC), the clinical and pathological features and prognosis factors, as well as types were analyzed retrospectively. MATERIALS AND METHODS This is a retrospective study of 277 patients with early-stage EC in clinical Stages I that received surgery between January 2000 and March 2008. The appropriate surgical procedures were divided into three types (procedure I-III: hysterectomy with or without ovary preservation, subradical hysterectomy plus pelvic lymph node biopsy, and radical hysterectomy pelvic plus lymphadenectomy) according to the clinical stage. RESULTS Tumor invasion of the cervix and deep muscularis as well as the parametrium, EC Stage Ib, grade 3 and ascites had carcinoma cells, were high-risk factors of EC metastasis to the retroperitoneum (p < 0.05). The ovarian preservation of EC Stage Ia had no effect on overall survival. The three types of procedure for the EC Stage Ia were not correlated significantly to the three-year and five-year survival rates. The three-year and five-year survival rates of three surgical procedures for the EC Stage Ib were significantly correlated. The survival rates of surgical procedures II and III were significantly higher than that of procedure I (P < 0.05). CONCLUSION Subradical hysterectomy plus pelvic lymph node biopsy was recommended for EC Stage 1b with high-risk factors. There was no evidence of benefit in terms of overall or recurrence-free survival for radical hysterectomy plus pelvic lymphadenectomy in women with Stage I EC.

Abstract
OBJECTIVE To investigate the antifungal ability of seven over-the-counter mouthwashes against planktonic and sessile Candida albicans and Candida krusei. MATERIALS AND METHODS The seven mouthwashes studied were Listerine, compound chlorhexidine solution, povidone iodine solution (PV-I), cetylpyridinium chloride solution, Colgate Plax, Crest Prohealth Mouthwash, and NaHCO3 . The antifungal ability of each mouthwash against ATCC90028, ATCC6258, and 10 clinical C. albicans isolates was tested using disk diffusion tests, the broth microdilution method, and biofilm testing with two different XTT-reduction assays. Fluconazole was used as a positive control, and the experiments were performed in triplicate. RESULTS Chlorhexidine and cetylpyridinium chloride had the largest inhibition zones for ATCC90028 and ATCC6258 (18.6 ± 3.5 and 19 ± 1.6 mm, respectively). Cetylpyridinium chloride was the most effective at inhibiting all of the planktonic C. albicans strains and ATCC6258 with the minimum inhibitory concentration (MIC). As the maturity of the biofilms increased, the change in sessile cell MIC of the mouthwashes was much smaller than that of fluconazole. For the mature biofilms, chlorhexidine, PV-I, and cetylpyridinium chloride produced the greatest reductions in metabolism (60-80%). CONCLUSION Most of these seven mouthwashes had significant antifungal activity for both planktonic and sessile Candida species.

Abstract
BACKGROUND A predominant Th17 population is a marker of allergic rhinitis (AR). As a ligand-activated transcription factor, the aryl hydrocarbon receptor (AhR) plays a vital role in promoting or inhibiting the development of specific Th cells. However, its role in AR remains undefined. OBJECTIVE To analyze the potential role of AhR in the pathogenesis of AR. METHODS In total, 30 AR patients and 13 healthy controls were recruited for this study and AR patients had clinical features, as demonstrated by rhinoconjunctivitis quality of life questionnaires, total symptom scores and visual analog scale scores. The expression of AhR, IL-17 and IL-22 and the presence of Th17 cells in peripheral blood mononuclear cells were measured before and after treatment with the nontoxic AhR ligand 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE). RESULTS Pretreatment ITE studies revealed that all AR patients had a significant increase in AhR expression compared with controls and AhR expression positively correlated with clinical parameters. After ITE intervention, a severe reduction in the differentiation of Th17 cells and the production of IL-17 and IL-22 was noted in both AR patients and normal subjects. Simultaneously, a dramatic enhancement of AhR expression was also observed in all healthy controls, but not in AR patients. CONCLUSION The results suggested that the AhR may be one of the mechanisms underlying the Th17 response during the pathogenesis of AR and AhR levels were closely related to clinical severity in all AR patients. Additionally, ITE may represent a new drug candidate in the treatment of AR.
