Abstract
A 64-year-old female patient was admitted to Beijing Chao-Yang Hospital on February 21, 2023 because of right-sided chest pain for more than 4 years and left-sided chest pain for more than 9 months. She had a past medical history of previous tuberculosis and rheumatoid arthritis. A chest CT in October 2018 revealed multiple pulmonary nodules. A CT-guided biopsy showed no tumors, and adenosine deaminase levels in the pleural effusion were elevated, suggesting a high likelihood of tuberculosis. As a result, anti-tuberculosis treatment was initiated in March 2019. In December 2019, she underwent a right lower lobe resection due to localized hydropneumothorax on the right side. Postoperative pathology unveiled granulomatous inflammation with necrosis. A chest CT in May 2020 showed a significant increase in nodules and cavities. In January 2023, a diagnosis of cryptococcal pneumonia was considered, and she was prescribed oral fluconazole. Finally, the diagnosis of pulmonary rheumatoid nodules was confirmed after a pathological consultation of the postoperative specimen. After one month of treatment with oral prednisone and mycophenolate mofetil, a follow-up chest CT showed improvement. It was recommended that she continue with her current treatment and undergo regular chest CT scans.

Abstract
In this article, we reported a 28-year-old female patient who presented with intermittent hemoptysis, cough, and sputum production. Laboratory tests showed no abnormalities in the blood counts or inflammatory markers, and the sputum cultures were negative. A chest computed tomography scan showed bronchiectasis associated with infection in the middle and lower lobes of the right lung and right pleural thickening. We performed bronchoalveolar lavage by bronchoscopy in the dorsal segment of the right lower lobe and found Mycobacterium avium intracellulare complex (MAC) by Next Generation Sequencing (NGS) of bronchoalveolar lavage fluid (BALF). The patient's symptoms improved significantly after anti-mycobacterium treatment and the extent of infection was reduced on imaging. To further identify the cause of bronchiectasis, the patient is tall and thin, with slender limbs. Cardiac color ultrasound showed the widening of aortic sinus. Her genetic testing of blood samples revealed the gene mutation in the FBN1 gene (c.4349G>A). Based on these results, she was diagnosed with Marfan syndrome.

Abstract
Objective: To understand the epidemiological characteristics of notifiable infectious diseases reported in Beijing in 2021 under the influence of the novel coronavirus pneumonia epidemic prevention and control policy, and provide reference evidence for the prevention and control of notifiable infectious diseases. Methods: Descriptive epidemiological methods were used to analyze the morbidity of notifiable infectious diseases reported in Beijing in 2021, with software R 4.1.2 for data process and ArcGIS 10.8 for visualization. Results: The morbidity of notifiable infectious diseases in Beijing in 2021 was 290.51/100 000, a decrease of 43.29% compared with 2020 and a decrease of 71.45% compared with the average during 2017-2019. The top 5 reported diseases with high morbidity were other infectious diarrhea, influenza, hand foot and mouth disease, pulmonary tuberculosis and syphilis. From the perspective of transmission route, intestinal infectious diseases were the main diseases, accounting for 50.15% (31 898/63 601) of the total cases. From the perspective of pathogens, viral infectious diseases were the main diseases, accounting for 59.63% (25 259/42 356) of the total cases. The laboratory diagnosis rate of notifiable infectious diseases reported in Beijing increased from the average of 16.47% (36 289/220 371) during 2017-2019 to 35.36% (22 490/63 601) in 2021. The laboratory diagnosis rate of parasitic infectious diseases was 83.33%. The districts with high incidence of intestinal infectious diseases were Pinggu, Miyun and Fengtai; Natural foci and insect borne infectious diseases were mainly reported in Yanqing, Mentougou, Fangshan and Daxing. Conclusion: The morbidity of notifiable infectious diseases in Beijing in 2021 showed a decrease trend. The laboratory confirmation rate of reported notifiable infectious disease cases increased, and there were great differences in the laboratory confirmation rate among different diseases. It is very necessary to improve the laboratory confirmation rate of the cases. The diseases with different transmission routes showed different geographical distributions. It is necessary to conduct the targeted prevention and control of infectious diseases in different areas.

Abstract
Objective: To evaluate the transmissibility of 2019-nCoV Omicron variant under the current prevention and control strategy in Beijing, and provide evidence for the prevention and control of COVID-19. Methods: The information of 78 Omicron variant infection cases involved in clear transmission chains in Beijing during 7-25 March, 2022 were collected, the incubation period and serial interval of the disease were fitted by using Gamma and Weibull distribution. Markov Chain Monte Carlo approach was used to estimate the time-varying reproduction number (Rt). Results: The median of the incubation period (Q1, Q3) of Omicron variant infection was 4.0 (3.0, 6.0) days, and the serial interval was 3.0 (2.0, 5.0) days. The median of the serial interval (Q1, Q3) was 2.0 (1.0, 4.0) days in unvaccinated cases and 4.0 (2.0, 6.0) days in vaccinated cases (Z=-2.12, P=0.034), and 2.0 (1.5, 3.0) days in children and 4.0 (2.0, 6.0) days in adults, respectively (Z=-2.02,P=0.044), the differences were significant. The mean of Rt was estimated to be 4.98 (95%CI: 2.22-9.04) for Omicron variant in this epidemic. Conclusion: Omicron variant has stronger transmissibility compared with Delta variant. It is necessary to strengthen the routine prevention and control COVID-19, promote the vaccination and pay close attention to susceptible population, such as children.

Abstract
A 53-year-old female patient with pulmonary nodules for more than 3 years was admitted to Beijing Chao-Yang Hospital because of cough and sputum with shortness of breath after exercise for 4 months. In the first two and a half years, her pulmonary nodules remained stable, after that the nodules increased obviously with interstitial changes. After admission, a venous thromboembolic (VTE) event was quickly detected with a marked increase in D-dimer. Then, based on the clues of VTE examination, bronchoscopy, gastroscope, positron emission tomography-CT, head magnetic resonance and other examinations were performed. The final pathological diagnosis was lung adenocarcinoma, mainly solid with mucus secretion, with mediastinal hilar lymph node metastasis, intrapulmonary metastasis and gastric metastasis. Gene detection of lung and stomach histopathological tissues showed positive EML4-ALK fusion gene. The patient received therapies with crizotinib, alectinib in sequence and anticoagulation. After 20-month treatment, a telephone follow-up showed that there was no significant limitation in her daily activities.

Abstract
Cryotherapy is one of the most common treatments for warts; however, pain during treatment and relatively high recurrence rates limit its use. Local hyperthermia has also been used successfully in the treatment of plantar warts. The aim of this study was to compare the clinical effectiveness of local hyperthermia vs cryotherapy for the treatment of plantar warts. This multi-centre, open, 2-arm, non-randomized concurrent controlled trial included 1,027 patients, who received either cryotherapy or local hyperthermia treatment. Three months after treatment, local hyperthermia and cryotherapy achieved complete clearance rates of 50.9% and 54.3%, respectively. Recurrence rates were 0.8% and 12%, respectively. Pain scores during local hyperthermia were significantly lower than for cryotherapy. Both local hyperthermia and cryotherapy demonstrated similar efficacy for clearance of plantar warts; while local hyperthermia had a lower recurrence rate and lower pain sensation during treatment.

Abstract
Melanoma is a fatal skin malignant tumor with a poor prognosis. We found that long noncoding RNA BASP1-AS1 is essential for the development and prognosis of melanoma. The methylation, RNA sequencing, copy number variation, mutation data, and sample follow-up information of melanoma from The Cancer Genome Atlas (TCGA) were analyzed using weighted gene co-expression network analysis and 366 samples common to the three omics were selected for multigroup clustering analysis. A four-gene prognostic model (BASP1-AS1, LOC100506098, ARHGAP27P1, and LINC01532) was constructed in the TCGA cohort and validated using the GSE65904 series. The expression of BASP1-AS1 was upregulated in melanoma tissues and various melanoma cell lines. Functionally, the ectopic expression of BASP1-AS1 promoted cell proliferation, migration, and invasion in both A375 and SK-MEL-2 cells. Mechanically, BASP1-AS1 interacted with YBX1 and recruited it to the promoter of NOTCH3, initiating its transcription process. The activation of the Notch signaling then resulted in the transcription of multiple oncogenes, including c-MYC, PCNA, and CDK4, which contributed to melanoma progression. Thus, BASP1-AS1 could act as a potential biomarker for cutaneous malignant melanoma.

Abstract
Background: Sarcomas are heterogeneous rare malignancies constituting approximately 1% of all solid cancers in adults and including more than 70 histological and molecular subtypes with different pathological and clinical development characteristics. Method: We identified prognostic biomarkers of sarcomas by integrating clinical information and RNA-seq data from TCGA and GEO databases. In addition, results obtained from cell cycle, cell migration, and invasion assays were used to assess the capacity for Tanespimycin to inhibit the proliferation and metastasis of sarcoma. Results: Sarcoma samples (N = 536) were divided into four pathological subtypes including DL (dedifferentiated liposarcoma), LMS (leiomyosarcoma), UPS (undifferentiated pleomorphic sarcomas), and MFS (myxofibrosarcoma). RNA-seq expression profile data from the TCGA dataset were used to analyze differentially expressed genes (DEGs) within metastatic and non-metastatic samples of these four sarcoma pathological subtypes with DEGs defined as metastatic-related signatures (MRS). Prognostic analysis of MRS identified a group of genes significantly associated with prognosis in three pathological subtypes: DL, LMS, and UPS. ISG15, NUP50, PTTG1, SERPINE1, and TSR1 were found to be more likely associated with adverse prognosis. We also identified Tanespimycin as a drug exerting inhibitory effects on metastatic LMS subtype and therefore can serve a potential treatment for this type of sarcoma. Conclusions: These results provide new insights into the pathogenesis, diagnosis, treatment, and prognosis of sarcomas and provide new directions for further study of sarcoma.

Abstract
The potato tuberworm moth (PTM) Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) is one of the most damaging pests of potato Solanum tuberosum L. in warm temperate and subtropical areas. Our previous experiment showed that extracts of larval frass of PTM deterred oviposition of conspecific females. In this study, we investigated the identification of chemicals in larval frass that were influencing the oviposition of PTM by behavioral bioassays and electroantennography analysis in the laboratory. Frass was collected from third and fourth instar larvae and combined analysis of gas chromatography coupled with electroantennography (GC-EAD) of dichloromethane extracts showed that eight compounds from larval frass extracts elicited repeatable antennal responses from mated females. Seven EAD-active compounds in frass volatile extract were identified by gas chromatography-mass spectrometry (GC-MS) as linoleic acid, octadecanoic acid, tricosane, pentacosane, heptacosane, nonacosane, and cholesterol. Oviposition bioassays indicated that frass extracts had a deterrent effect on egg laying, the deterrent activity increased with the concentration of frass extracts, and the threshold value for statistical significance in oviposition deterrence was in the range of 20-200 mg frass per cage. Linoleic acid, pentacosane, heptacosane, nonacosane, and cholesterol in larval frass volatiles were found to play a key role in repelling oviposition in a dose-dependent manner. We suggest that the bioactive compounds in larval frass are responsible for repelling oviposition of PTM, and n-alkanes, especially pentacosane, strongly deter oviposition and may be considered as a potential oviposition deterrent for potential applications.

Abstract
MicroRNA-210 (miRNA-210) has been reported to be associated with angiogenesis and may serve important roles in acute myocardial infarction (AMI), which remain unclear. The present study sought to evaluate the efficacy of miRNA‑210 in AMI and to examine the potential associated mechanisms. AMI models were established in Sprague‑Dawley rats. The expression of miRNA‑210 was upregulated via transfection with lentivirus‑mediated agonists and quantitative analysis was performed using the reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR). Immunoblotting and RT‑qPCR were separately used to detect the expression levels of hepatocyte growth factor (HGF) in heart samples, while only the protein expression level of β‑myosin heavy chain (β‑MHC) was assessed. The expression of HGF in human umbilical vein endothelial cells under hypoxic conditions was silenced by transfecting with small interfering RNA, as demonstrated by the determination of associated protein expression levels. The microvessel density (MVD) of the infarcted myocardium was selected to be the angiogenesis efficacy endpoint, which was evaluated by platelet endothelial cell adhesion molecule immunostaining. Markedly increased expression of HGF was observed among the AMI rats receiving miRNA‑210 agonists, demonstrated via quantitative analyses using RT‑qPCR or western blotting. Promotion of angiogenesis was observed with the increased MVD. Improved cardiac function in the rats was subsequently noted, as they exhibited improved left ventricular fractional shortening and left ventricular ejection fraction percentages, which may result from improved cardiac contractility indicated by attenuating the increase in β‑MHC protein expression. Overexpression of miRNA‑210 appeared to be an advantageous therapeutic tool for treating AMI, primarily due to its promoting effects on angiogenesis in the infarcted myocardium by stimulating HGF expression and inducing improved left ventricular remodeling, leading to improved cardiac function.

Abstract
Objective: To understand the probability of premature mortality caused by non-communicable diseases (NCD) in Beijing from 2010 to 2015. Methods: The data of deaths from Beijing vital registration system were used to analyze age-standardized NCD mortality rates, proportion of NCD deaths in age group <70 years and premature NCD mortality. Results: NCD deaths accounted for 90% of the total deaths in Beijing. Age-standardized NCD death rate decreased from 332.43/100 000 in 2010 to 280.02/100 000 in 2015. Meanwhile, the probability of deaths from four NCDs between in age group 30-70 years (premature NCD mortality) decreased from 12.81% to 11.11% in Beijing. The premature mortality of four NCDs in men was 14.63%, and compared with 2015 baseline, it would decrease by 16.4% to reach 2025 goal (12.23%), and the probability of premature mortality four NCDs in women was 7.54%, and compared with 2015 baseline, it would decrease by 6.8% to reach the 2025 goal (7.03%). People living in suburb areas had a higher probability of premature NCD mortality (13.67%) than those living in urban areas (9.72%) in Beijing in 2015. Conclusions: The premature NCD mortality was much higher in men than in women in Beijing. More attention should be paid to the control of risk factors for NCD premature deaths, especially in men and in suburb residents, to reach the 25×25 goal.

Abstract
Circular RNAs (circRNAs) are a type of non-coding RNAs that have been identified as critical regulators in various diseases, especially in cancers. However, the expression profiles and functions of circRNAs in cervical cancer are still unclear. In present study, human circRNAs microarray were performed to screen the circRNAs expression in cervical cancer tissue. Microarray analysis revealed 45 significantly expressed circRNAs with 4 fold change. Among these up-regulated circRNAs, hsa_circ_0018289 was validated to be significantly up-regulated in 35 pairs of cervical cancer tissue compared with adjacent normal tissue and cell lines. Loss-of-function experiments revealed that, in vitro and in vivo, hsa_circ_0018289 knockdown inhibited the proliferation, migration and invasion of cervical cancer cells. Via bioinformatics prediction program and luciferase reporter assays, hsa_circ_0018289 was observed to directly bind to miR-497. Taken together, the results indicate that hsa_circ_0018289 plays important role in cervical cancer proliferation, migration and invasion, suggesting the miRNA 'sponge' of hsa_circ_0018289 and its oncogenic role on cervical cancer tumorigenesis.

Abstract
INTRODUCTION Tartrate-resistant acid phosphatase 5 (ACP5), which is essential for bone resorption and osteoclast differentiation, promotes cell motility through the modulation of focal adhesion kinase phosphorylation. This study seeks to elucidate the association of ACP5 expression and the clinicopathologic characteristics of patients with lung adenocarcinoma (AD). METHODS The expression of ACP5 was measured by Immunohistochemistry and Western blot analysis in lung AD and matched tumor-adjacent tissues, and the χ2 test was applied to analyze the correlation between ACP5 expression and clinicopathologic features. Using the Kaplan-Meier method, univariate and multivariate regression analysis was to explore the correlation between ACP5 expression and overall survival (OS). RESULTS We found that ACP5 was frequently upregulated in lung AD tissues. The high expression of ACP5 was significantly related to lymph node status, tumor-node-metastasis (TNM) stage, and differentiation. From the results of univariate survival analysis, it indicated that the patients with high expression of ACP5 expression had a significantly lower OS than the patients with low expression of ACP5 expression. As it showed in Multivariate Cox regression analysis, the high expression of ACP5 expression was an independent prognostic factor for OS. CONCLUSIONS Our results suggest that high expression of ACP5 correlates with tumor progression and may serve as a potential prognostic biomarker in lung AD.

Abstract
OBJECTIVES To explore the criminal characteristics of forensic psychiatry expertise in depression patients and schizophrenics with homicide behavior. METHODS A total of 40 depression (depressive episode) patients and 50 schizophrenics with homicide behavior were randomly assigned into the study group and control group, respectively. Data of demographic and criminal characteristic of the two groups were collected by a self-designed questionnaire, and then were compared. RESULTS There were no statistical differences in age, education level and career between study and control groups (P>0.05). Compared with the control group, the victims in the study group were mainly the patient's children and parents, and most offenders had suicidal behavior after homicide (70%). In study group, the motives of crime were mainly extended suicide and indirect suicide, and most offenders had attempted suicide (85%) and diminished capacity of criminal responsibility (70%), which in control group had no capacity of criminal responsibility (56%). Except for criminal site, there were statistical differences in other criminal characteristics between two groups (P<0.05). CONCLUSIONS There are different criminal characteristics between depression patients and schizophrenics with homicide behavior in forensic psychiatry, and these characteristics should be considered when these two diagnoses are distinguished in forensic psychiatry expertise.

Abstract
Understanding the photoexcited carrier-relaxation actions in ultrasmall black phosphorus quantum dots (BPQDs) will play a crucial role in the fields of electronics and optoelectronics. Herein, we report the ultraviolet (UV) saturable absorption and ultrafast photoexcited carrier-relaxation dynamics of BPQDs. The ultrasmall BPQDs are synthesized using a facile liquid-exfoliation method and possess a diameter of 3.8 ± 0.6 nm and a thickness of 1.5 ± 0.4 nm. Femtosecond open-aperture (OA) Z-scan measurements showed typical saturable absorption properties in the UV band. A negative nonlinear optical (NLO) absorption coefficient of -(1.4 ± 0.3) × 10-3 cm GW-1 and a saturable intensity of 6.6 ± 1.3 GW cm-2 were determined. Using a degenerate pump-probe technique, an ultrafast photoexcited carrier-recombination time was observed in the range of 216-305 fs, which was 3 orders of magnitude faster than that of BP nanosheets. Such an ultrafast relaxation component may be attributable to the edge- and step-mediated recombination and was confirmed by our density functional theory (DFT) calculations. This work provides fundamental insight into the underlying mechanism of the photoexcited carrier relaxation dynamic action in BPQDs which can enable UV photonic devices.

Abstract
Emerging evidence suggests that the long noncoding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) gene is involved in the pathogenesis of cervical cancer. However, the potential mechanism is rarely reported. Our study found that PVT1 was upregulated in cervical cancer tissue and cell lines. After transfecting PVT1 siRNA, the proliferation, migration, and invasion of cervical cancer cells were markedly decreased. miRNA expression profiles demonstrate that miR-424 was markedly downregulated in cervical cancer tissue. Bioinformatics analysis revealed that miR-424 was potentially targeted by PVT1, which was confirmed by dual-luciferase reporter assay. Pearson's correlation analysis showed that PVT1 expression was negatively related to miR-424 expression in glioma cancer tissues. Finally, lowered expression of miR-424 could recover the tumor-suppressive effects of PVT1 knockdown in cervical cancer cell lines. Our results reveal a tumor-promoting role for PVT1, acting as a competing endogenous RNA (ceRNA) or a molecular sponge in negatively modulating miR-424, which might provide a novel therapeutic target for cervical cancer.

Abstract
OBJECTIVE To fill up the absence of data on causes of death of urban residents in Beijing during 1965-1974 and provide evidence for the similar study in other areas. METHODS All possible sources for death data during 1965-1974 were identified through expert consultations and record search. Stratified sampling was conducted to collect the death data of urban residents during this period in Beijing. The mortality rate, death cause constituent and rank of death causes were used in this descriptive analysis. RESULTS A total of 11 668 records of deaths from 1965 to 1974 were collected from 10 local police stations in urban area of Beijing. The top 10 death causes in the urban residents were heart disease, tumor, cerebrovascular disease, accidental injury, respiratory system disease, digestive system disease, communicable disease and parasitic disease, nervous system disease, urogenital and reproductive system disease, endocrine and nutrition metabolic diseases. The deaths caused by these diseases accounted for 84.19% of the total deaths. Accidental injury accounted for 13.22% of the total deaths, which was significantly higher than that in either 1964 or 1975, two years before and after this period(P<0.01). Suicide accounted for 54.47% of the total accidental injury deaths. For men, accidental injury was the leading death cause, followed by cancer and heart disease; for women, heart disease, cancer and cerebrovascular disease were the top three death causes. CONCLUSION The major death cause in urban residents changed from infectious diseases to chronic and non-communicable diseases during 1965-1974. A remarkable high proportion of deaths caused by accidental injury was due to the historical background during that period in Beijing, China.

Abstract
OBJECTIVE The International Hip Outcome Tool (iHOT-33) is a questionnaire designed for young, active patients with hip disorders. It has proven to be a highly reliable and valid questionnaire. The main purpose of our study was to adapt the iHOT-33 questionnaire into simplified Chinese and to assess its psychometric properties in Chinese patients. METHOD The iHOT-33 was cross culturally adapted into Chinese and 138 patients completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the EuroQol-5D (EQ-5D), and the Chinese version of the iHOT-33(SC-iHOT-33) pre- or postoperatively within 6 months' follow-up. The Cronbach's alpha, intraclass correlation coefficient (ICC), Pearson's correlation coefficient (r), effect size (ES), and standardized response mean (SRM) were calculated to assess the reliability, validity, and responsiveness of the SC-iHOT-33, respectively. RESULTS Total Cronbach's alpha was 0.965, which represented excellent internal consistency of the SC-iHOT-33. The ICC ranges from 0.866 to 0.929, which shows excellent test-retest reliability. The subscales of SC-iHOT-33 had the highest correlation coefficient (r = 0.812) with the physical function subscales of the WOMAC, as well as good correlation between the social/emotional subscale of the SC-iHOT-33 and the EQ-5D (r = 0.740, r = 0.743). No floor or ceiling effects were found. The ES and SRM values indicated good responsiveness of 2.44 and 2.67, respectively. CONCLUSION The SC-iHOT-33 questionnaire is reliable, valid, and responsive for the evaluation of young, Chinese, active patients with hip disorders.

Abstract
Axillary branching is controlled by a very complex mechanism involving various endogenous and environmental factors. Previous studies have shown that Tb1/BRC1 is the point of integration in the network of molecular mechanisms regulating axillary branching in plants. In this study, we cloned the Tb1/BRC1 ortholog, NtBRC1, from Nicotiana tabacum and functionally analyzed its role in the control of axillary branching in tobacco. Overexpression of NtBRC1 resulted in significant retardation of axillary branching, and downregulation of this gene resulted in significant acceleration of axillary branching after decapitation. This indicates a negative role for this gene in the regulation of axillary branching. In-line with previous reports, NtBRC1 was found to be expressed predominantly in axillary buds. Additionally, as expected, expression was decreased 8 h following decapitation, which further confirms its role in the suppression of axillary branching. Furthermore, the expression of NtBRC1 was significantly downregulated by cytokinin, but was not affected by GR24, a synthetic strigolactone. Based on the data collected in the present study, we demonstrate that NtBRC1 negatively regulates axillary branching in tobacco after decapitation and functions downstream of the cytokinin signaling pathway inside axillary buds.

Abstract
Background The optimal antiplatelet regimen after in-coronary intervention among patients presenting with complex coronary artery lesions or acute coronary syndrome (ACS) has remained unclear. This study sought to evaluate the clinical outcomes of triple antiplatelet treatment (TAPT) (cilostazol added to aspirin plus clopidogrel) in these patients. Methods The PubMed, EMBASE, MEDLINE, and other Internet sources were searched for relevant articles. The primary end point was major adverse cardiac events (MACE), including all-cause mortality, myocardial infarction, and target vessel revascularization. The incidence of definite/probable stent thrombosis and bleeding were analyzed as the safety end points. Results Eleven clinical trials involving 9,553 patients were analyzed. The risk of MACE was significantly decreased following TAPT after stent implantation in the ACS subgroup (odds ratio [OR]: 0.72; 95% confidence interval [CI]: 0.61–0.85; P<0.001), which might mainly result from the lower risk of all-cause mortality in this subset (OR: 0.62; 95% CI: 0.48–0.80; P<0.001). The risk of bleeding was not increased with respect to TAPT. Conclusion TAPT after stent implantation was associated with feasible benefits on reducing the risk of MACE, especially on reducing the incidence of all-cause mortality among patients suffering from ACS, without higher incidence of bleeding. Larger and more powerful randomized trials are still warranted to prove the superiority of TAPT for such patients.

Abstract
OBJECTIVE To understand the main influencing factors related to healthy life expectancy (HALE) among adults in Beijing. METHODS The calculation on health-adjusted life expectancy was performed by Sullivan METHODS. Data from the self-reported health survey program on adults in Beijing 2012 was gathered. Hierarchical ordered probit model was used to estimate the severity-weighted prevalence of disability and then combined with the period life table to obtain the HALE. Factors associated with the severity-adjusted prevalence of the disabled were analyzed under the generalized additive models (GAM). RESULTS The main influencing factors of HALE would include age (t=40.351, P<0.001), sex (t=9.689, P<0.001), levels of education (t=5.021, P< 0.001), exercise (t=5.487, P<0.001) and alcohol intake (t=-2.380, P=0.017) etc. The influence of per capita monthly income (χ(2) =3.949, P=0.044) showed as non-linear. CONCLUSIONS Levels of income would directly influence the severity-weighted prevalence of the disability, which also affecting the HALE. Programs on improving healthy life style and health care in women should be promoted.

Abstract
Thyrotropin receptor (TSHR) is a G-protein-coupled receptor that regulates the synthesis, storage, and secretion of thyroid hormones in the thyroid tissue. The aims of the present study were to characterize the full-length TSHR cDNA in largemouth bass (Micropterus salmoides), and to determine the TSHR gene transcription levels in different tissues. In addition, the response of TSHR transcription levels to daily feeding in thyroid tissue was investigated. The results showed that the full-length cDNA sequence was 2743 bp with an open reading frame of 2340 bp encoding a 779-amino acid peptide. BLAST analysis indicated that the amino acid sequence displayed 58.4-90.2% identity and 5.6-125.8 divergence, compared with other known fish species. The most abundant TSHR transcription levels were found in the spleen, head kidney, and kidney. Feeding did not affect the transcription level of TSHR in thyroid tissue over the course of the day. Thus, the current study suggests that there was no relationship between daily nutritional status and TSHR transcription level in the thyroid tissue of largemouth bass. The spleen, head kidney, and kidney exhibited the most abundant TSHR transcription levels.

Abstract
OBJECTIVE This study aimed to investigate the expression of osteopontin (OPN), p2lras, and CD44V6 in breast cancer tissues, and to analyze the relationships between their expression and a patient's clinicopathological characteristics and five-year survival rate. MATERIALS AND METHODS Streptavidin-peroxidase immunohistochemistry was used to detect the expression of OPN, p2lras, and CD44V6 in tissue samples from 96 breast cancer patients, and the multivariate Cox proportional hazards model (mCOX-PHM) was used to analyze the factors that affect prognosis. RESULTS Among the 96 breast cancer patients studied, positive staining for OPN, CD44V6, and p21ras was observed in 54.2%, 58.3%, and 43.8% of samples, respectively. The expression of OPN and CD44V6 were positively correlated (r = 0.58), and the expression of OPN and p21ras were also positively correlated (r = 0.25). Coexpression OPN, CD44V6, and p21ras was negatively correlated with a patient's five-year survival rate (p < 0.05). Kaplan-Meier analysis indicated that a patient without OPN, CD44V6, or p21ras expression had an improved survival (p < 0.05). Results from the mCOX-PHM analysis indicated that CD44V6 expression, the degree of tumor differentiation, and lymph node metastasis were all independent factors that indicate prognosis. The combined detection of OPN, CD44V6, and p21ras could contribute to a more accurate assessment of the biological behavior of breast cancers, and could help to indicate the prognosis of breast cancer patients.

Abstract
OBJECTIVES In recent years, Chinese hospital settings are under violent threats. The exact status of quality of life of Chinese doctors under these disastrous situations remains obscure. The aim of this study was to assess the quality of life of Chinese urologists and analyse its potential affecting factors. DESIGN Cross-sectional survey. SETTING Beijing, China. PARTICIPANTS Overall, 1000 participants from more than 30 areas of China, who participated in the 20th National Urology Conference in Beijing in 2013, were surveyed. The brief version of the World Health Organization Quality of Life (WHOQOL-BREF) Chinese version was used to assess the quality of life among these urologists. The relationship between quality of life and the affecting factors was analysed. RESULTS Of the 1000 questionnaires, 856 were completed and returned, and 708 questionnaires were valid for analysis. Approximately 46% of the respondents came from provincial capitals, 54.2% of them felt stress from medical environment, while 76.0% felt stress from research work, and 85.3% from promotion. Cronbach's α coefficient of the instrument was 0.825, Kaiser-Meyer-Olkin measure was 0.841, and P value of Bartlett's sphericity was <0.001. The results of binary logistic regression indicated gender, work years, and medical environment as potential affecting factors of quality of life only influenced one domain. In contrast, research work and promotion influenced three domains of the WHOQOL-BREF. CONCLUSIONS The study indicated that the WHOQOL-BREF may be a reliable and valid tool to assess quality of life of Chinese urologists. In China it is true that the deteriorative medical environment negatively affects medical practice according to previous studies, and policies are recommended to improve the situation. Nevertheless, we should not be too pessimistic about it, as in today's context research work and promotion may be the most extensive and significant affecting factors on doctors' quality of life.

Abstract
To demonstrate the safety and efficacy of combine laparoscopy and flexible ureteroscopy to treat ectopic pelvic kidneys with ureteropelvic junction obstruction (UPJO) and stones. 16 patients of ectopic pelvic kidneys with ureteropelvic junction obstruction and stones were treated with laparoscopy and flexible ureteroscopy (FURS). The operative time, required dose of tramadol, visual analog pain scale (VAPS), postoperative day, stone-free rates (SFRs), perioperative complications, and serum creatinine were evaluated. The SFRs were evaluated with noncontrasted renal computed tomography (CT). Intravenous pyelography (IVP) and CT scan were used to evaluate the UPJO. Stone-free status was defined as absence of stone fragments in kidney or the size of that is less than 3 mm. Operation time from 118 to 225 min, average time (171 ± 28) min; lithotomy time from 16 to 45 min, average time (32 ± 6) min. Average tramadol required at the first day postoperation was (118 ± 49.6) mg; at the second day was (78 ± 24.8) mg. VAPS score at 24 h (5.0 ± 0.7), VAPS score at 48 h (2.5 ± 0.8). Postoperative day (3.9 ± 0.6) days. Stone-free rate was 100%. Average serum creatinine was (88.7 ± 24.3) mol/L before surgery and (92.8 ± 21.6) mol/L after surgery. No major complication. No stone and obstruction recurrence in the follow-up of average 29.3 months. Combined FUR and LC is a good option for patient of ectopic pelvic kidney with renal stone and UPJO. From our initial experience, the SFRs and the effect of pyeloplasty are satisfactory and without major complication, the operative time is acceptable.

Abstract
Aortic dissection is a life-threatening emergency. Well-established risk factors include systemic hypertension, hereditary connective tissue diseases (Marfan syndrome and Ehlers-Danlos syndrome), coarctation of the aorta, bicuspid aortic valve, aortitis, and arch hypoplasia. Ischemia of the viscera, the kidneys, the spinal cord, or the lower extremities due to malperfusion constitutes life-threatening complications that have to be considered in the treatment strategy.We report a rare case of symptomatic ischemia of the lower extremities due to aortic dissection. This case demonstrates that the treating physician needs to be vigilant for ischemia reperfusion injuries such as osteofascial compartment syndrome and acute renal failure in aortic dissection.

Abstract
A model Zr41.25Ti13.75Ni10Cu12.5Be22.5 (at.%) bulk metallic glass (BMG) is selected to explore the structural evolution on the atomic scale with decreasing temperature down to cryogenic level using high energy X-ray synchrotron radiation. We discover a close correlation between the atomic structure evolution and the strength of the BMG and find out that the activation energy increment of the concordantly atomic shifting at lower temperature is the main factor influencing the strength. Our results might provide a fundamental understanding of the atomic-scale structure evolution and may bridge the gap between the atomic-scale physics and the macro-scale fracture strength for BMGs.

Abstract
Haemaphysalis qinghaiensis ticks collected in the Gannan Tibet Autonomous Region were infested onto a sheep from a Babesia-free area. A strain of small Babesia (1.8-2.1 microm in length) was isolated from the sheep. Most of the Babesia in erythrocytes were round, oval, single pyriform, double pyriform, budding or elongated in form. Measurements were made of 100 single sides of the double-pyriform Babesia and compared with those for B. motasi and B. ovis from Holland, using Student's t-test. The Gannan small Babesia was similar to the B. ovis from Holland, but differed significantly from the Dutch B. motasi.

Abstract
A rapid, sensitive and specific diagnostic method, an enzyme-linked immunosorbent assay (ELISA), was developed for the diagnosis of Theileria sp. infection in sheep; and optimal conditions were established, such as antigen concentration, serum dilution, coating time, Tween-20 concentration and conjugate. The results were analyzed by measuring the coefficient of variation (CV). Three sera titers (high, middle, low) were analyzed over the measurement range, resulting in a CV of around 10%, whereas a 30% variation is the maximum acceptable. The cut-off value was determined by the mean of a negative control plus three standard deviations. Cross-reaction was found only with Babesia ovis. However, this result may be questionable, because it cannot be excluded that these sheep were already infected with both Theileria sp. and B. ovis. The ELISA described in the present study proved to be a useful tool for studying the epidemiology of Theileria sp.

Abstract
A compound effective for the treatment of ovine theileriosis was selected and a slow-release preparation (named Kangjiaoming) was prepared. A total of 1,172 sheep and goats in Zhangjiachuan, Lintan and Yuzhong Counties, Gansu Province, where small ruminants are seriously affected by theileriosis, were injected with this preparation at a dosage of 5 mg/kg body weight. The infection rate of the control group in each of the above-mentioned counties was 98.5%, 85% and 80%, respectively. None of the treated animals became sick due to theileriosis. This drug proved to be useful for the treatment of carrier cases, although its effect was apparently slower than in acute theileriosis. The effect of the preparation on some weak animals was not satisfactory.

Abstract
In this study, we assessed the expression of activation markers on gammadelta T cells in central nervous system (CNS) lesions of SJL mice adoptively sensitized to develop experimental autoimmune encephalomyelitis (EAE) using myelin basic protein-reactive T cells. Although disease expression is known to be dependent upon T cells that express the alphabeta T cell receptor (TCR), a role for gammadelta T cells has been implicated in some studies but not in others. Using three-color flow cytometric analysis of both total and gammadelta T cells in spleen and CNS, the data showed that expression of CD69 (early activation marker), CD62L (lymphocyte homing receptor), CD25 (IL-2Ralpha), CD122 (IL-2Rbeta) and CD95/CD95L (Fas/FasL), fluctuated on gammadelta T cells in EAE lesions in a disease-related fashion. Furthermore, the pattern of expression for these markers on gammadelta T cells was distinct from that found on the total lymphocyte population. Cytokine analysis of gammadelta T cells in the CNS demonstrated a bias towards a Th1-like cytokine profile. From these data, we conclude that gammadelta T cells in EAE lesions display an activated phenotype and form a dynamic component of the total lymphocyte population in the CNS, supporting a contributory role for these cells.

Abstract
The purpose of this study was to examine the effects of calcitonin gene-related peptide (CGRP) on coronary flow and various parts of cardiac conduction system (CCS) in the isolated guinea pig heart by recording the cardiac electrogram and His bundle activity simultaneously. The coronary flow (CF) was measured and the right atrium was paced at incremental frequencies periodically. Perfusing heart with CGRP at the concentrations of 3 30 nmol/L increased CF strikingly and dose-dependently. CGRP (30 nmol/L) caused a moderate and significant increase in the spontaneous heart rate, but failed to influence the atrioventricular nodal and His bundle-Purkinje fiber conduction time and the longest atrial pacing cycle length inducing 3 2 Wenckebach and 2 1 AV nodal conduction. The results indicate that CGRP in the guinea pig heart might act mainly on coronary vessels and then the sinus node, but did not affect the conductivity and refractoriness of the AV conduction system.

Abstract
Glial growth factor 2 (GGF2) is a neuronal signal that promotes the proliferation and survival of the oligodendrocyte, the myelinating cell of the central nervous system (CNS). This study has focused on recombinant human GGF2 (rhGGF2) and it's potential to affect clinical recovery and repair to damaged myelin in chronic relapsing experimental autoimmune encephalomyelitis (EAE) in the mouse, a major animal model for the human demyelinating disease, multiple sclerosis (MS). Mice with EAE were treated with rhGGF2 during both the acute and relapsing phases, and GGF2 treatment led to delayed signs, decreased severity and resulted in statistically significant reductions in relapse rate. Further, rhGGF2-treated groups displayed CNS lesions with more remyelination than in controls. This correlated with increased expression of myelin basic protein exon 2, a marker for remyelination, and with an increase of the regulatory cytokine, IL-10. Thus, a beneficial effect of a neurotrophic growth factor has been demonstrated upon the clinical, pathologic and molecular manifestations of autoimmune demyelination, an effect that was associated with increased expression of a Th2 cytokine. rhGGF2 treatment may represent a novel approach to the treatment of MS (Cannella et al., 1998).

Abstract
In this study we present evidence that gammadelta T cells are present in the normal mouse central nervous system (CNS). Compared with matching spleen gammadelta T cells, CNS gammadelta T cells expressed only the CD45RBlow phenotype, suggesting that CNS gammadelta T cells belong to the memory cell population. Approximately 20% expressed exclusively the CD8alphabeta heterodimer, consistent with a thymic origin. Gammadelta T cells in both spleen and CNS expressed higher levels of the IL-2rbeta (CD122), as well as Fas and FasL, than alphabeta T cells, suggesting that these cells function as immunoregulatory T cells. RT-PCR analysis showed almost exclusive use of Vdelta6 in the CNS whereas more Vdelta genes were expressed in the spleen. Sequencing of Vdelta6 RT-PCR products demonstrated a polyclonal population of T cells in the spleen but a more clonal population within the CNS. The predominant CNS sequence was found in all animals studied and was also detected in the spleen. From these data we conclude that a selective component of circulating gammadelta T cells traffics through the CNS. Thus, all major populations of lymphocytes can be detected in the normal CNS and as such may play specific roles in the immunological surveillance of that organ.

Abstract
We wished to study how infections might trigger relapses of autoimmune diseases such as multiple sclerosis (MS) and encephalomyelitis (EAE). We hypothesized that immune responses to heat shock proteins (hsp) induced by an infection could modulate responses to autoantigens. We induced extra-neuraxial inflammation in SJL mice housed either in specific-pathogen free (SPF) or conventional facilities. Mice in conventional housing are continuously exposed to large numbers of infectious agents. Spleen cell proliferative responses to human HSP60 and bacterial HSP65 were measured as were numbers of cells secreting IFN-gamma or IL-5. Proliferative responses to HSP60 were increased in conventionally housed mice compared to SPF mice and this was associated with skewing of secreted cytokines toward a Th2 pattern. Skewing toward a Th1 pattern was noted in SPF mice. Acute and relapsing EAE was induced in both groups of mice. Acute EAE was, in general, equivalent in all groups. However, SPF mice had more severe relapses than did conventionally housed animals and these differences were amplified by extra-neuraxial inflammation. Immunocytochemical analyses of brains from mice with relapsing EAE showed that increased numbers of brain gamma/delta cells were associated with disease remission. Our data suggest that frequent exposure to infectious agents leads to a relative Th2 skewing of immune responses to hsp and that this is associated with milder, less frequent relapses of EAE. They also support the concept that immune responses to hsp are of potential importance in exacerbating and perpetuating organ-restricted autoimmune diseases.

Abstract
Abstract
The Fas and FasL apoptotic pathway was investigated by protein immunohistochemistry, flow cytometry, and reverse transcriptase-PCR analysis to assess whether it is involved in the elimination of target and/or effector cells from the central nervous system (CNS) during adoptively transferred chronic relapsing experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis. In addition to Fas and FasL, we studied Bax, an intracellular protein of the apoptotic cascade, the Bax antagonist and anti-apoptotic molecule Bcl-2, and DNA fragmentation, the final step in the apoptotic pathway. Infiltrating CD4+ T cells and parenchymal microglia expressed Fas, FasL, and Bax, and about half of these cells showed DNA fragmentation, a combination indicative of ongoing apoptosis. Using flow cytometry and reverse transcriptase-PCR, a positive correlation was seen between disease activity and up-regulation of the Fas system; in fact, Fas and FasL were expressed at low levels at the onset of EAE and increased at the height of disease to involve about one-third of all infiltrating lymphocytes. In the normal CNS, Fas immunoreactivity was constitutively present at low levels on oligodendrocytes and was up-regulated in the CNS during the course of EAE. However, oligodendrocytes showed no Bax reactivity or DNA fragmentation and expressed high levels of Bcl-2, as did the majority of infiltrating CD3+ cells, a pattern inconsistent with apoptosis. Thus, while molecules of the apoptotic cascade are well represented in the CNS during EAE, their expression correlates with elimination of infiltrating cells and microglia, not the myelinating cell, the oligodendrocyte.

Abstract
Mice adoptively-sensitized to develop chronic relapsing experimental autoimmune encephalomyelitis (EAE), a model for the human demyelinating condition, multiple sclerosis (MS), were given injections of recombinant human IL-10 at various timepoints post-sensitization in an attempt to abrogate disease development. IL-10 is a Th2 immunomodulatory cytokine with known down-regulatory effects upon Th1 responses and macrophages. Contrary to a previous report on EAE and the predicted outcome, after repeated experiments, IL-10 was found to elicit a worsening or no effect upon EAE in the mouse. Animals were studied clinically, histopathologically and immunocytochemically. On no occasion was disease ameliorated by IL-10. Pretreatment with IL-10 of lymph node cells used to transfer EAE had no effect upon disease outcome, indicating that the cells were already committed effectors. Administration of anti-IL-10 monoclonal antibody before onset of signs had no effect when given early post-sensitization and caused marked worsening when given immediately before onset of signs. In the context of this autoimmune demyelinating model, these results suggest that IL-10 alone is insufficient to reverse the effector response and indeed may serve to enhance the cascade of events in EAE.

Abstract
Previous studies have detected gamma delta T cells in multiple sclerosis and experimental allergic encephalomyelitis (EAE) lesions but their role remains obscure. In the present study, we assessed gamma delta T cell dynamics and distribution in spleen and central nervous system (CNS) from mice with relapsing-remitting EAE, and studied the effect of depleting these cells on clinical and pathologic expression of disease using the mAb GL3. By immunohistochemistry and FACS analysis, striking disease-related changes were observed in the gamma delta T cell population in the CNS. FACS analysis showed that while gamma delta T cells remained low in the spleen (approximately 2% total CD3+ T cells) at all stages, in the CNS they increased to approximately 12% at the height of the acute attack, fell to approximately 5% during the recovery phase, but rose again to approximately 12% during the chronic phase. In animals in which gamma delta T cells were depleted immediately before the onset of acute disease, or during the chronic stage, a striking and significant reduction in the severity of the clinical signs was observed that was associated with a decrease in the percentage of CD3+/gamma delta T cells in the CNS. In depleted animals a statistically significant reduction in inflammation and demyelination was noted during the acute stage, but only marginal effects on these disease parameters were found in the chronic phase. Taken together, the data support the conclusion that gamma delta T cells play an important role in the pathogenesis of EAE in mice during both acute and chronic/progressive phases of the disease process.
