Abstract
Objective: To examine the characteristics and trends regarding the 30-day coronary heart disease (CHD) readmission rates in patients discharged for acute myocardial infarction (AMI) in Beijing, during 2007-2012. Methods: Patients hospitalized for AMI in Beijing from 1 January 2007 to 31 December 2012 were identified from "The Cardiovascular Disease Surveillance System in Beijing". In total, 64 355 patients aged 25 years and over with permanent Beijing residency survived and discharged for AMI in Beijing during the above-said six years. After excluding duplicate and validation for the completeness and accuracy of the records, clinical features and 30-day CHD readmission rates for those AMI discharged patients were analyzed. Trends regarding the 30-day CHD readmission rates in patients discharged for AMI were analyzed by Poisson regression models. Results: The overall age-standardized average 30-day CHD readmission rate for AMI discharged patients was 7.7% in patients aged 25 years and over in Beijing. During the six years under study, an increasing trend was observed on the 30-day CHD readmission rates for AMI discharged patients after adjusting the age and gender (P<0.001). The age-standardized 30-day CHD readmission rates for AMI discharged patients increased by 21.3% in the past six years, from 7.0% in 2007 to 8.5% in 2012. The increase of 30-day CHD readmission rates was noted in both men and women during the six years, whereas it appeared higher in women (8.4%) than in men (7.4%), after adjusting for age. Among the AMI discharged patients, the 30-day CHD readmission rates were higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than those with ST-segment elevation myocardial infarction patients (P<0.01), and higher in discharged patients with multiple comorbidities than those without multiple comorbidities (P<0.01). Conclusions: An increasing trend in the 30-day CHD readmission rates for AMI discharged patients was observed during 2007-2012 among Beijing residents aged 25 years and over. It called for an urgent need in improving the secondary prevention of AMI discharged patients, particularly in women, with NSTEMI and those with multiple comorbidities. Findings from these unselected "real-world" data in Beijing may help to guide the management of AMI in the country as well as in other developing countries.

Abstract
OBJECTIVE To characterize a species of the genus Tricula and parasitized trematodes in schistosomiasis-endemic areas of Yunnan Province using a molecular analysis, so as to understand their taxonomic positions. METHODS Tricula spp. and Oncomelania snails were collected from Xiangyun County, Yunnan Province, and cercaria parasitizing snails were observed using crushing followed by microscopy. Cercaria parasitizing Tricula snails at various morphologies were sampled using a shedding method. Genomic DNA was extracted from snail soft tissues and cercariae, and the 16S rRNA, COI, 28S rDNA genes in snails and the ND1 and 28S rDNA genes in cercariae were amplified using a PCR assay and sequenced. The species of Tricula snails and their parasitized trematodes was characterized using sequence alignment and phylogenetic analysis. RESULTS Among 382 Tricula snails detected, there were three types of trematode cercariae found, including the non-forked (20.94%, 80/382), double-forked (3.40%, 13/382) and swallow shapes (7.07%, 27/382). Sequence and phylogenetic analyses showed that the 16S rRNA, COI and 28S rDNA gene sequences of this species of Tricula had high homology to those in Delavaya dianchiensis, and were clustered in a branch. Sequencing analysis of the ND1 and 28S rDNA genes revealed that the non-forked cercariae belonged to the family Pleu- rogenidae, the swallow-shaped cercariae belonged to the family Opecoelidae, and the double-forked cercariae belonged to another species of the genus Schistosoma that was different from S. sinensium and S. ovuncatum. CONCLUSIONS The species and taxonomy of Triculla spp. and their parasitized trematodes are preliminarily determined in schistosomiasis-endemic areas of Yunnan Province; however, further studies are required to investigate the more definite taxonomy and pathogenicity.

Abstract
Objective: To explore the characteristics of humor in young adult epileptic patients and examine the relationship between humor and depression. Methods: We recruited 55 young adult epileptic patients who visited outpatient clinic of the Department of Neurology of Yijishan Hospital of Wannan Medical College between October 2018 and March 2019 and 44 healthy controls to complete the multidimensional humor scale (MSHS), humor style questionnaire (HSQ) and Beck depression scale-Ⅱ (BDI-Ⅱ), and compared their differences between the two groups. Results: The results showed that the young adult patients with epilepsy (PWEs) were affected in humor creation, coping with humor and the totally scores of MSHS. The scores of humor creation, coping with humor and the totally scores of MSHS in the young epilepsy patients were 25.3±5.9, 16.7±5.0 and 61±10, which were significantly lower than those in the control group 29.8±6.1, 21.1±2.6 and 71±8. As for the humor style, self-defeating humor scores in PWEs were higher than controls 14±5 vs 9±3, and the self-enhancing humor scores were lower than controls 18±7 vs 23±6. The scores of BDI-Ⅱ in PWEs were significantly higher than those of normal controls 13±7 vs 6±4. Pearson's correlation test showed that the scores of BDI-Ⅱ were negatively correlated with humor creation, coping with humor, the totally scores of MSHS and self-enhancing humor scores (r=-0.566--0.721, P<0.05), while it was positively correlated with self-defeating humor scores (r=0.818, P<0.05). Among the clinically relevant factors, the scores of BDI-Ⅱ were correlated with seizure control and gender. Multiple stepwise linear regression showed that coping with humor, self-defeating and self-enhancing humor scores were closely related with depression in young epileptic adults. Conclusion: The young adults with epilepsy are affected in sense of humor and humor style, which are closely related with depression.

Abstract
The early diagnosis and effective treatment of hepatocellular carcinoma (HCC) still remains a difficult problem that plagues the medical community. Exosomes are microvesicles with a diameter of 40~100 nm, and contains proteins, lipids and nucleic acids (mRNAs, lncRNAs, circRNAs, and microRNAs). They serve as an information exchange carrier, and play an important role in regulating and controlling the biomolecular function to maintain the stability of the intracellular environment. The function of exosomes in HCC includes intercellular communication, neoangiogenesis, cancer cell metastasis and multidrug resistance, which mediates the transformation of microRNAs (miRNA) and regulate the microenvironment of tumor progression, and then affect the pathophysiological behavior of cancer cells. Exosome-derived miRNA can be used for HCC monitoring or potential specific markers of early diagnosis. In addition, with the development and application prospects it could be a therapeutic goal for HCC. This paper summarizes the recent progress in the study of HCC-derived exosomal miRNA.

Abstract
Objective: To investigate the Wnt3a expression in tissues of HCC and its gene knockout on effects of HepG2 cell proliferation or xenograft tumor growth. Methods: Hepatic Wnt3a expressions in 87 HCC and their matched surrounding tissues were observed by tissue microarray and immunohistochemistry for analyzing its clinicopathological characteristics; Wnt3a-knockout HepG2 cell lines were established by Crispr/cas9-sgRNA system and genomic cleavage efficiency was verified at gene level by surveyor assay. The relative proteins were confirmed by Western blotting; Cell Counting Kit-8 assay was used to examine cell proliferation after knocking-out Wnt3a successfully, and the nude mice HepG2 cell xenograft tumors delete that the relationship between Wnt3a and HCC growth. Results: The positive Wnt3a with brown staining particles was mainly distributed in cytosol and membrane of hepatocytes. The incidence of hepatic Wnt3a expression in cancerous tissues (95.4%) was significantly higher (χ (2) = 47.754, P < 0.001) than that in their surrounding tissues (49.4%). The high Wnt3a expression was 70.1% in the HCC and only 14.9% in the surrounding tissues. High Wnt3a expression was associated with poorly-differentiated grade, liver cirrhosis, HBV infection, portal vein invasion, TNM stage and 5-year survival rate. After knocked-out by Crispr/cas9-sgRNA system successfully, Wnt3a expression was down-regulated significantly at gene or protein level. Key molecule β-catenin in cytoplasma was obviously inhibited. HepG2 cell lines proliferation was suppressed in time-dependent manner. The nude mice HepG2 cell xenograft tumors confirmed that the knock-out of Wnt3a could significantly supressed HCC growth with slower speed (t = 6.418, P < 0.001), smaller volume(869.4 ± 222.5 mm(3) vs 355.0 ± 99.9 mm(3), t = 5.168, P < 0.001), and lighter weight (0.88 ± 0.20 g vs 0.35 ± 0.11 g, t = 5.628, P < 0.001)compared with the control group. Conclusion: Abnormal expression of Wnt3a could be expected as a promising target for HCC gene therapy.

Variations in submicron aerosol liquid water content and the contribution of chemical components during heavy aerosol pollution episodes in winter in Beijing. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 693:133521. [PMID: 31377367 DOI: 10.1016/j.scitotenv.2019.07.327] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 07/14/2019] [Accepted: 07/20/2019] [Indexed: 05/21/2023]
Abstract
The aerosol liquid water content (ALWC) of submicron particles (PM1) was calculated in this work by three methods based on the aerosol physical and chemical properties measurement campaigns in winter in Beijing, including (a) the PM1 volume difference between the ambient and dry states by applying the particle number size distribution and particle hygroscopicity measurement; (b) the thermodynamic equilibrium model (ISORROPIA II) based on the chemical composition; and (c) the κ-Köhler theory of chemical composition with a volume mixing scheme. The three methods agreed well with reasonable uncertainties. The ALWC showed an exponential trend depending on the relative humidity (RH), and an abundant ALWC was also favored by the high PM1 mass loading. The contribution of different chemical component to the ALWC was evaluated by the κ-Köhler method, which revealed that during the measurement, the inorganics and organics could contribute to ~80% and ~20%, respectively, under ambient RH conditions, with the largest contributor of ammonium nitrate. When the RH was above 85%, the mass concentration of ALWC was comparable to, or even larger than, that of the dry PM1.

Abstract
Undoped CaFe2As2 (Ca122) can be stabilized in two slightly different non-superconducting tetragonal phases, PI and PII, through thermal treatments. Upon proper annealing, superconductivity with a Tc up to 25 K emerges in the samples with an admixture of PI and PII phases. Systematic low-temperature X-ray diffraction studies were conducted on undoped Ca122 samples annealed at 350 °C over different time periods. In addition to the diffraction peaks associated with the single-phase aggregation of PI and PII, a broad intermediate peak that shifts with annealing time was observed in the superconducting samples only. Our simulation of phase distribution suggests that the extra peak is associated with the admixture of PI and PII on the nanometer scale. High-resolution transmission electron microscopy confirms the existence of these nano-scale phase admixtures in the superconducting samples. These experimental results and simulation analyses lend further support for our conclusion that interfacial inducement is the most reasonable explanation for the emergence of superconductivity in undoped Ca122 single crystals.

Abstract
Abstract
Hot embossing was used to fabricate a microneedle array on poly(methyl methacrylate) (PMMA) substrates. Both experimental and numerical researches were carried out to investigate the whole formation process. The results showed that the edge effect would significantly influence the replication rate of final products. An optimization design of convex flow barrier was proposed to improve the replication efficiency and structure uniformity. Furthermore, optimum parameters of the flow barrier were found to be 2 mm in length and 0.2 mm in height. Reasonable high molding temperature and force were conducive to reduce the filling time and increase the average height of microneedles.

Abstract
Objective: To investigate the association between the plasma levels of 20 amino acids and the risk of diabetes in middle-aged and elderly population. Methods: This study was a part of the Chinese multi-provincial cohort study conducted in communities of Shougang. In 2007 and 2012, the population was investigated for diabetes and other risk factors. Blood samples collected from 475 people were tested for various amino acid levels by liquid chromatography-tandem mass spectrometry. A multivariate logistic regression analysis was used to analyze the association between plasma amino acid levels and diabetes risk. Results: The age of the selected population at baseline was (58.7±6.3) years, and the blood glucose level at baseline was (5.68±1.34) mmol/L. Among them, 56 (11.79%) subjects were diabetes. Multivariate logistic regression analyses showed that after adjusting for age, gender, body mass index, systolic blood pressure and dyslipidemia, individuals with plasma branched-chain amino acid (valine, leucine and isoleucine) and cysteine in the highest tertile levels were at high risk of diabetes with the ORs of 3.61 (95% CI 1.48-8.80), 3.27 (95% CI 1.34-7.99), 2.46 (95% CI 1.04-5.84) and 2.09 (95% CI 1.02-4.27), respectively. After 5 years' followed up, 5.73% (24/419) subjects developed diabetes. Compared with those in the lowest tertile, individuals with plasma branched-chain amino acid (total concentration), phenylalanine, and tyrosine levels at baseline in the highest tertile had 3.69 times, 3.61 times and 4.14 times higher risk to develop new diabetes, respectively. In contrast, individuals with plasma glycine level in the highest tertile had only 76% (OR 0.24, 95% CI 0.06-0.91) risk for the development of diabetes compared with those with plasma glycine level in the lowest tertile. Conclusions: The increase in plasma branched-chain amino acid and cysteine levels is significantly associated with an increase in incident diabetes. Subjects with higher levels of branched-chain amino acids and aromatic amino acids (phenylalanine, tyrosine) had a significantly higher risk of developing new-onset diabetes, while those with higher glycine levels had a significantly lower risk of developing diabetes in 5 years.

Abstract
Objective: To explore the association between long-term changes in blood pressure (BP) levels and the incidence of cardiovascular diseases (CVD). Methods: A total of 5 752 participants, who participated baseline examination in 1992-1993 and re-examination in 2007, were followed up till December 31, 2013 according to the study protocol of the Chinese Multi-provincial Cohort Study. Participants were stratified by baseline BP and re-examination BP and cross-combined into 9 subgroups. The 20-year incidence of acute cardiovascular events, acute coronary heart disease (CHD) and acute stroke events were analyzed and association between disease incidence and 15-year changes in BP were determined using the competing risk regression model. Results: (1) There were 523 CVD events (170 CHD, 373 stroke) during the 20 years follow up. The number of participants with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) of <130/80 mmHg (1 mmHg=0.133 kPa), 130-139/80-89 mmHg, and hypertension were 2 892 (50.3%), 1 328 (23.1%) and 1 532 (26.6%), respectively. (2) Among participants with baseline SBP of 130-139 mmHg or DBP of 80-89 mmHg, 870 (65.5%) progressed to hypertension and 279 (21.0%) maintained at the same stratum over a 15-year follow up period. (3) After adjustment for age, sex, body mass index, smoking status, diabetes, total cholesterol, and high-density lipoprotein cholesterol at baseline, participants maintained SBP/DBP at 130-139/80-89 mmHg had a higher risk of developing acute cardiovascular events, CHD and stroke with the hazard ratios (HR) and 95% confidence interval (95%CI) of 2.04 (1.16, 3.57), 3.29 (1.30, 8.35) and 1.63 (0.80, 3.33), compared with those who maintained their SBP < 130 mmHg and DBP <80 mmHg. Participants whose BP increased from 130-139/80-89 mmHg to hypertension over the follow up period had 2.81-fold (1.84, 4.29), 3.17-fold (1.43, 7.03) and 2.71-fold (1.65, 4.44) higher risk for the incidence of acute cardiovascular events, CHD, and stroke, respectively, compared with participants who maintained their SBP <130 mmHg and DBP <80 mmHg. Conclusions: Participants with SBP/DBP of 130-139/80-89 mmHg have a high long-term risk for progression to hypertension. Sustained exposure to SBP/DBP of 130-139/80-89 mmHg or higher increases the risk of CVD incidence, and our results highlight the importance of early prevention for participants with this BP stratum.

Abstract
Objective: To understand the distribution and trends in 30-day coronary heart disease (CHD) case fatality rate in patients hospitalized due to acute myocardial infarction (AMI) in Beijing during 2007-2012. Methods: The clinical data of patients hospitalized due to AMI in Beijing from 1 January 2007 to 31 December 2012 were collected from "The Cardiovascular Disease Surveillance System in Beijing" . A total of 77 943 local patients aged ≥25 years were hospitalized due to AMI in Beijing during the this period. After excluding duplicate records and validation for the completeness and accuracy of the records, the clinical characteristics of the patients and 30-day CHD case fatality rate in the patients were analyzed. Trends in 30-day CHD case fatality rate in the patients were analyzed with Poisson regression models. Results: The age-standardized average 30-day CHD case fatality rate was 9.7% in the 77 943 patients. During this period, a decreasing trend was observed in 30-day CHD case fatality rate after adjusting for age and gender (P<0.001). The age-standardized 30-day CHD case fatality rate decreased by 16.0%, from 10.8% in 2007 to 9.0% in 2012. The decreases of 30-day CHD case fatality rates were noted in both men and women, whereas 30-day CHD case fatality rate was higher in women (14.1%) than in men (7.6%) after adjusting for age. During this period, the proportion of ST-segment elevation myocardial infarction (STEMI) decreased, while the proportion of non-ST-segment elevation myocardial infarction (NSTEMI) increased with year. A significant decline (20.1%) in 30-day case fatality rate of STEMI was found, but no decline was found for 30-day mortality rate of NSTEMI. Conclusion: A decreasing trend in 30-day CHD case fatality rate was observed in the patients aged ≥25 years and hospitalized due to AMI in Beijing during 2007-2012, indicating the improvement in short-term prognosis of patients hospitalized due to AMI. Our findings highlight the urgent need to improve the treatment for woman and NSTEMI patients.

Abstract
Objective: To evaluate the impact of different intervention models on adherence to secondary prevention therapies in patients with acute coronary syndrome (ACS). Methods: This multi-center cross-sectional study collected data from 34 hospitals covering 22 provinces in China. Hospitals were randomly divided into four groups: control group(routine treatment and care), promotional calendar group (routine treatment and care plus giving propaganda desk calendar to patients), education group (routine treatment and care add patients education by nurses) and combined intervention group (promotional calendar and education).At least 90 patients with ACS were consecutively enrolled from each involved hospital from April 15, 2012 to June 30, 2013. To reduce the impact of uneven distribution of inter-group variables on the results, 1∶1∶1∶1 propensity score matching method was used. The drug usage for secondary prevention and prognosis wasobtainedat 6 months after hospital discharge.

Abstract
Objective: To compare the clinical value of two quantitative methods in analyzing endobronchial ultrasound real-time elastography (EBUS-RTE) images for evaluating intrathoracic lymph nodes. Methods: From January 2014 to April 2014, EBUS-RTE examination was performed in patients who received EBUS-TBNA examination in Shanghai Chest Hospital. Each intrathoracic lymph node had a selected EBUS-RTE image. Stiff area ratio and mean hue value of region of interest (ROI) in each image were calculated respectively. The final diagnosis of lymph node was based on the pathologic/microbiologic results of EBUS-TBNA, pathologic/microbiologic results of other examinations and clinical following-up. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were evaluated for distinguishing malignant and benign lesions. Results: Fifty-six patients and 68 lymph nodes were enrolled in this study, of which 35 lymph nodes were malignant and 33 lymph nodes were benign. The stiff area ratio and mean hue value of benign and malignant lesions were 0.32±0.29, 0.62±0.20 and 109.99±28.13, 141.62±17.52, respectively, and statistical differences were found in both of those two methods (t=-5.14, P<0.01; t=-5.53, P<0.01). The area under curves was 0.813, 0.814 in stiff area ratio and mean hue value, respectively. The optimal diagnostic cut-off value of stiff area ratio was 0.48, and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 82.86%, 81.82%, 82.86%, 81.82% and 82.35%, respectively. The optimal diagnostic cut-off value of mean hue value was 126.28, and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 85.71%, 75.76%, 78.95%, 83.33% and 80.88%, respectively. Conclusion: Both the stiff area ratio and mean hue value methods can be used for analyzing EBUS-RTE images quantitatively, having the value of differentiating benign and malignant intrathoracic lymph nodes, and the stiff area ratio is better than the mean hue value between the two methods.

Abstract
Objective: To investigate the methods and short-time clinical results of reconstruction of Paprosky type Ⅲ acetabulum bone defects by using tantalum augments. Methods: A total of 17 patients (17 hips) with Paprosky type Ⅲ acetabulum bone defects, treated with tantalum augments in revision of total hip arthroplasty at Department of Orthopedics Surgery in General Hospital of Chinese People's Liberation Army were retrospectively analyzed from March 2014 to May 2016.There were 6 males and 11 females aged from 23 to 74 years with an average of (50.2±16.3) years. Tantalum augments or TM-Cup augment (the cup-on-cup technique) were used to reconstruct the defects.The TM-Cup augment was the tantalum revision cup which was removed titanium ring. The cup-on-cup technique combined TM-Cup augment and biological acetabulum cup. Augments were served as the nonresorptive structural allograft in revision of total hip arthroplasty. Harris hip score was used to evaluate clinical effects. The vertical position of the rotation center was measured and analyzed. Radiographic assessments of the acetabular components were performed by DeLee-Charnley and the Anderson criteria and recorded postoperative complications. Results: All the patients were followed up from 3 to 29 months with an average of (16.2±5.4) months, tantalum augments and biological acetabulum cup were used in 13 patients, the TM-Cup augment and biological acetabulum cup were used in 4 patients. At the time of the latest follow-up, the mean Harris hip score increased compared to preoperatively (86.8±8.3 vs. 30.0±12.0) (t=12.78, P<0.01), the average vertical location of the center of rotation was decreased ((25.3±9.8) mm vs.(47.6±10.5)) mm (t=4.95, P<0.01). All the tantalum augments and biological acetabulum cups were stable, there were no infection, dislocation and other complications. Conclusions: The use of tantalum augments could be considered as an effective management of Paprosky type Ⅲ defects providing good clinical and radiographic outcomes in the short term.The cup-on-cup technique which was used in reconstruction of severe superior-invagination acetabular bone defects and restoration relatively normal center of rotation had special application value.

Abstract
Temporary strict emission control strategies were conducted to ensure good air quality for China's V-Day parade (August 20-September 3, 2015) in Beijing and nearby cities. The influence of the emission control on particle number size distribution (PNSD) was evaluated based on the long-term measurements of PNSD at a rural site (Shangdianzi) located northeast of Beijing. This study also presented the comparison results of PNSD during the parade in 2015 and the Olympics in 2008 (August 8-23), as well as the same period without strict emission control in 2010-2013 (August 20-September 3). Compared with the same period in 2010-2013 and 2008 Olympics, the accumulation mode particle number concentration showed a significant reduction in 2015, and the PM1 mass concentration decreased by approximately 60-90%. The alleviation of the PM1 was also associated with the weather conditions. The back trajectories analysis results showed that the southerly air mass passing through the polluted areas accounted for 14% of the total back trajectories in 2015, which contributed to approximately 60% in the other years. During the control period in 2015, there were six new particle formation (NPF) events observed, with a higher frequency, but a lower formation rate and growth rate than the same period in 2010-2013. The comparison of the condensation sink (CS), sulfuric acid, solar radiation and relative humidity among the different years indicated that at Shangdianzi station, the first factor in determining the NPF occurrence was the CS, and the second factor could be the concentration level of precursor vapors participating in the NPF event (e.g., sulfuric acid).

Abstract
We evaluated the association between GSTM1, GSTT1, and GSTP1 IIe105Val gene polymorphisms and treatment outcomes of advanced non-small cell lung carcinoma. Between January 2010 and December 2012, a total of 244 patients with non-small cell lung carcinoma were recruited from Yiwu Central Hospital. The GSTM1, GSTT1, and GSTP1 IIe105Val gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism and the results were statistically analyzed. Conditional regression analysis, showed that individuals carrying the null GSTM1 were associated with an increased risk of response to chemotherapy when compared to the present GSTM1 (odds ratio = 1.88, 95% confidence interval (CI) = 1.01-3.47). Moreover, the GG genotype of GSTP1 IIe105Val was associated with a better response to chemotherapy compared to the AA genotype (odds ratio = 2.77, 95%CI = 1.14-6.64). The null GSTM1 genotype was associated with a lower risk of death from all causes when compared with the present GSTM1 genotype (hazard ratio = 2.16, 95%CI = 1.10-4.38). Moreover, the GG genotype of GSTP1 IIe105Val was correlated with a reduced risk of death from all causes compared with the AA genotype (hazard ratio = 2.94, 95%CI = 1.11-8.68). In conclusion, we found that the null GSTM1 and the GG genotype of GSTP1 IIe105Val were correlated with a good response to chemotherapy and improved overall survival of advanced non-small cell lung carcinoma patients.

Abstract
The Chinese fire-bellied newt, Cynops orientalis, belonging to Amphibia, Caudata, Salamandridae is a species endemic to China. The liver, which is an important digestive gland and the largest amphibian organ, has various functions, including detoxification, glycogen storage, protein synthesis, and hormone production. However, the newt liver has rarely been studied at the molecular level. We performed histomorphology and high-throughput proteomic analysis of the Chinese fire-bellied newt liver, using hematoxylin and eosin (H&E) staining and two-dimensional electrophoresis coupled with mass spectrometry. The H&E staining showed that the newt liver nuclei are large and round, are located in the lateral cytoplasm, and contain a large quantity of lipid droplets. Melanins were abundantly present throughout the hepatic parenchyma. The proteome analysis showed a total of 545 proteins detected in the newt liver. Furthermore, a gene ontology analysis suggested that these proteins were associated with metabolism, immune response, cellular homeostasis, etc. Among these, proteins with metabolic functions were found to be the most abundant and highly expressed. This supports the role of the liver as the metabolic center. The proteomic results provide new insights into the aspects of the liver proteomes of the Chinese fire-bellied newt. The identification of a more global liver proteome in the newt may provide a basis for characterizing and comparing the liver proteomes from other amphibian species.

Abstract
To better understand the cloud condensation nuclei (CCN) activation capacity of aerosol particles in different pollution conditions, a long-term field experiment was carried out at a regional GAW (Global Atmosphere Watch) station in the Yangtze River Delta area of China. The homogeneity of aerosol particles was the highest in clean weather, with the highest active fraction of all the weather types. For pollution with the same visibility, the residual aerosol particles in higher relative humidity weather conditions were more externally mixed and heterogeneous, with a lower hygroscopic capacity. The hygroscopic capacity (κ) of organic aerosols can be classified into 0.1 and 0.2 in different weather types. The particles at ~150 nm were easily activated in haze weather conditions. For CCN predictions, the bulk chemical composition method was closer to observations at low supersaturations (≤0.1%), whereas when the supersaturation was ≥0.2%, the size-resolved chemical composition method was more accurate. As for the mixing state of the aerosol particles, in haze, heavy haze, and severe haze weather conditions CCN predictions based on the internal mixing assumption were robust, whereas for other weather conditions, predictions based on the external mixing assumption were more accurate.

Abstract
Aquaglycero-aquaporins (agAQPs) are the structural foundation of rapid water transport and they appear to participate in cancer proliferation and malignancy. AQP3 expression is increased and AQP9 expression is decreased in hepatocellular carcinoma (HCC) compared to normal liver, which suggests their possible use as targets for cancer treatment. AQP-based modifiers, such as Auphen and dibutyryladenosine 3', 5'-cyclic monophosphate (dbcAMP), might be used to treat several diseases and as chemical tools for assessing the functions of AQPs in biological systems. We investigated the effects of both Auphen on AQP3 and dbcAMP on AQP9 in SMMC-7721 cells. We used western blotting, real-time quantitative polymerase chain reaction (qPCR) and immunohistochemistry to evaluate changes in AQP3 and AQP9 expression in SMMC-7721 cells after culturing with Auphen and dbcAMP, respectively. We also determined the proliferation of SMMC-7721 cells. We found that compared to HL-7702 (L02) liver cells, Auphen increased AQP3 expression in tumor cells, whereas dbcAMP decreased expression of AQP9 in these cells. Also, high concentrations of Auphen and dbcAMP inhibited proliferation of SMMC-7721 cells in vitro. Auphen and dbcAMP may inhibit HCC development and could be considered targets for HCC diagnosis and therapy.
