Abstract
Objective: To explore the application of manual screening collaborated with the Artificial Intelligence TPS-Assisted Cytologic Screening System in urinary exfoliative cytology and its clinical values. Methods: A total of 3 033 urine exfoliated cytology samples were collected at the Henan People's Hospital, Capital Medical University, Beijing, China. Liquid-based thin-layer cytology was prepared. The slides were manually read under the microscope and digitally presented using a scanner. The intelligent identification and analysis were carried out using an artificial intelligence TPS assisted screening system. The Paris Report Classification System of Urinary Exfoliated Cytology 2022 was used as the evaluation standard. Atypical urothelial cells and even higher grade lesions were considered as positive when evaluating the recognition sensitivity, specificity, and diagnostic accuracy of artificial intelligence-assisted screening systems and human-machine collaborative cytologic screening methods in urine exfoliative cytology. Among the collected cases, there were also 1 100 pathological tissue controls. Results: The accuracy, sensitivity and specificity of the AI-assisted cytologic screening system were 77.18%, 90.79% and 69.49%; those of human-machine coordination method were 92.89%, 99.63% and 89.09%, respectively. Compared with the histopathological results, the accuracy, sensitivity and specificity of manual reading were 79.82%, 74.20% and 95.80%, respectively, while those of AI-assisted cytologic screening system were 93.45%, 93.73% and 92.66%, respectively. The accuracy, sensitivity and specificity of human-machine coordination method were 95.36%, 95.21% and 95.80%, respectively. Both cytological and histological controls showed that human-machine coordination review method had higher diagnostic accuracy and sensitivity, and lower false negative rates. Conclusions: The artificial intelligence TPS assisted cytologic screening system has achieved acceptable accuracy in urine exfoliation cytologic screening. The combination of manual screening and artificial intelligence TPS assisted screening system can effectively improve the sensitivity and accuracy of cytologic screening and reduce the risk of misdiagnosis.

Abstract
Objective: To explore the moderating mechanism of mindfulness on perceived stress and job burnout of medical staff. Methods: From November 2020 to March 2022, 1626 medical staff were investigated by questionnaires. Chinese Version Perceived Stress Scale (CPSS), Maslach Burnout Inventory-Human Service Survey (MBI-HSS) and Mindful Attention Awareness Scale (MAAS) were used to evaluate the perceived stress, three dimensions of job burnout[depersonalization (DP), emotional exhaustion (EE), personal accomplishment (PA) ], and mindfulness level of medical staff. The Spearman rank correlation analysis was used to analyze the correlation between mindfulness and perceived stress, job burnout of medical staff. And the SPSS PROCESS macro program was used to test the moderating effect of mindfulness on perceived stress and job burnout. Results: Among the 1626 medical staff, 57.38% had perceived stress with health risk (933/1626), and 63.84% (1038/1626) had job burnout, among them, with 618 (38.01%), 274 (16.85%), and 146 (8.98%) experiencing mild, moderate and severe job burnout, respectively. The scores of mindfulness among medical staff were significantly correlated with perceived stress and various dimensions of job burnout (EE, DP and PA) (r(s)=-0.155, -0.351, -0.315, 0.307, P<0.001). Mindfulness had a moderating effect between perceived stress and job burnout, which was achieved through three moderating pathways: perceived stress-mindfulness-EE, perceived stress-mindfulness-DP and perceived stress-mindfulness-PA (ΔR(2)=0.073, 0.06, 0.006, P<0.001) . Conclusion: Medical staff have a high level of job burnout, mindfulness plays a moderating role between perceived stress and job burnout. Specific measures can be taken to improve the level of mindfulness in medical staff, so as to prevent and alleviate job burnout of medical staff.

Abstract
The incidence of diabetic kidney disease (DKD) is sharply increasing worldwide. Microalbuminuria is the primary clinical marker used to identify DKD, and its initiating step in diabetes is glomerular endothelial cell dysfunction, particularly glycocalyx impairment. The glycocalyx found on the surface of glomerular endothelial cells, is a dynamic hydrated layer structure composed of pro-teoglycans, glycoproteins, and some adsorbed soluble components. It reinforces the negative charge barrier, transduces the shear stress, and mediates the interaction of blood corpuscles and podocytes with endothelial cells. In the high-glucose environment of diabetes, excessive reactive oxygen species and proinflammatory cytokines can damage the endothelial glycocalyx (EG) both directly and indirectly, which induces the production of microalbuminuria. Further research is required to elucidate the role of the podocyte glycocalyx, which may, together with endothelial cells, form a line of defense against albumin filtration. Interestingly, recent research has confirmed that the negative charge barrier function of the glycocalyx found in the glomerular basement membrane and its repulsion effect on albumin is limited. Therefore, to improve the early diagnosis and treatment of DKD, the potential mechanisms of EG degradation must be analyzed and more responsive and controllable targets must be explored. The content of this review will provide insights for future research.

Abstract
Choline is an essential nutrient that plays an integral role in all stages of the life cycle, with increasing interest in the relationship between choline and neurodevelopment. Choline is a major component in the synthesis of phospholipids, phosphatidylcholine and sphingolipids, and is an essential nutrient for methyl metabolism, acetylcholine synthesis and cell signaling. Choline plays an important role in neurogenesis and neural migration during fetal development, potentially influencing the development and prognosis of neurological disorders, but its mechanism of action is not yet clear. This article reviews the source and metabolism of choline, the effects and mechanism of choline on neurodevelopment and central nervous system related disorders.

Abstract
Objective: To investigate the pain status in diabetic foot ulcer (DFU) patients and analyze its influencing factors. Methods: A single-center cross-sectional survey research method was used. From May 2021 to February 2022, DFU patients who were admitted to the Fourth Medical Center of PLA General Hospital and met the inclusion criteria were selected and investigated. The scores of the heaviest pain, the least pain, the average pain, and the current pain in pain degree and the total score and the scores of influence on patients' daily life, mood, walking ability, daily work, relationship with others, sleep, and life interest in pain-related effects and the total score of patients were evaluated by the brief pain inventory. A self-designed general data questionnaire was used to collect the data including patients' gender, age, education level, body mass index, self-care ability, diabetes course, wound Wagner grade, bacterial culture result of wound specimen, and the levels of glycated hemoglobin, albumin, prealbumin, hemoglobin, and leukocyte count. Patients were classified according to general data, and the total scores of pain degree and pain-related effects were counted. Data were statistically analyzed with Kruskal-Wallis test and Mann-Whitney U test. The indicators with statistically significant differences in univariate analysis were selected for generalized linear model analysis to screen the independent risk factors of pain severity and pain-related effects in DFU patients. Results: A total of 44 questionnaires were sent out, and 42 valid questionnaires were collected, with effective recovery of 95.45%. The scores of the heaviest pain, the least pain, the average pain, and the current pain in DFU patients were 5 (0, 10), 2 (0, 6), 3 (0, 8), and 2 (0, 8), respectively, and the total score of the pain severity was 11 (0, 24); the scores of pain-related effects on patients' daily life, mood, walking ability, daily work, relationship with others, sleep, and life interest were 4 (0, 10), 4 (0, 10), 5 (0, 10), 5 (0, 10), 3 (0, 10), 4 (0, 10), and 4 (0, 10), respectively, and the total score of pain-related effects was 30 (0, 63). In 42 DFU patients, most patients were male, aged 39-87 (67±10) years, most patients had education level of junior high school, most patients had diabetes for more than 20 years, half of patients' wounds were Wagner grade 4, most patients had body mass index and leukocyte count within normal limits, most patients had partial dependence on self-care ability, the bacterial culture results of wound specimen in the vast majority of patients were positive, about half of the patients had abnormal level of albumin, and most patients had abnormal levels of glycosylated hemoglobin, prealbumin, and hemoglobin. Univariate analysis of the above general data showed that total scores of pain severity among patients with different hemoglobin levels and leukocyte counts were statistically significant different (with Z values of -2.05 and -2.55, respectively, P<0.05), and the total scores of pain-related effects on patients with different hemoglobin levels, leukocyte counts, and bacterial culture results of wound specimen were statistically significant different (with Z values of -2.66, -2.02, and -2.12, respectively, P<0.05). Generalized linear model analysis showed that leukocyte count was an independent risk factor for pain severity and pain-related effects in 42 DFU patients (with 95% confidence intervals of 0.28-11.87 and 5.67-36.99, respectively, standardized regression coefficient values of 6.17 and 21.33, respectively, both P values <0.05). The bacterial culture result of wound specimen was an independent risk factor for pain-related effects in 42 DFU patients (with 95% confidence interval of 2.92-39.09, standardized regression coefficient value of 21.00, P<0.05). Conclusions: DFU patients often suffer pain, and the bacterial culture results of wound specimen and leukocyte count are the main factors affecting the pain of DFU patients.

Abstract
The prolongation of patient's overall survival is the accepted as gold standard to prove clinical values of anti-cancer drugs. However, if overall survival is taken as the primary endpoint in clinical trials for cancer types with a relatively good prognosis in the process of new anti-cancer drug research and development, the time to market the drugs will be prolonged due to the long follow-up time. In addition, overall survival is often interfered by confounding factors such as follow-up treatment. Therefore, regulatory agencies have established an accelerated review model using surrogate endpoints for the approval of new anti-cancer drugs, but there are still some problems in the use of surrogate endpoints in cancer clinical trials. From the perspective of new drug review, the authors expounds the key points of confirming and rationally using surrogate endpoints in clinical trials of anti-cancer drugs, which will improve the level of clinical trials of new anti-cancer drugs and accelerate the development of anti-tumor drugs.

Abstract
Single-arm trial refers to a clinical trial design that does not set up parallel control group, adopts open design, and does not involve randomization and blind method. These features, on the one hand, speed up the process of clinical trials, significantly shorten the time to market and meet the needs of patients with advanced malignancies, but also lead to the uncertainty of single-arm clinical trials themselves. Recently, the US Food and Drug Administration held a meeting of the oncologic drug advisory committee to discuss six tumor indications that have been accelerated approved, which once again triggered the discussion of single-arm trials. The basis of accelerated approval by single-arm trial is actually a compromise on the level of evidence-based medical evidence requirements after assessing the benefit risk. Therefore, the sponsor should strictly grasp the applicable conditions of single-arm trial in anti-tumor drugs and conduct single-arm trial scientifically. Post-marketing clinical trial should be implement as early as possible to ensure the benefit of patients. Based on the characteristics of single-arm trial, combined with two guidance relevant to single-arm trial issued by National Medical Products Administration recently, this article is supposed to propose and summarize the strategy of single-arm trial supporting the marketing of anti-tumor drugs.

Abstract
Objective: To investigate the feasibility, safety and efficacy of intrathecal pemetrexed (IP) treated for patients with leptomeningeal metastases (LM) from solid tumors. Methods: Forty-seven patients receiving pemetrexed intrathecal chemotherapy in the First Hospital of Jilin University from 2017 to 2018 were selected. The study of pemetrexed intrathecal chemotherapy adopted the classical dose-climbing model and included 13 patients with meningeal metastasis of non-small cell lung cancer who had relapsed and refractory after multiple previous treatments including intrathecal chemotherapy. Based on the dose climbing study, 34 patients with meningeal metastasis of solid tumor who did not receive intrathecal chemotherapy were enrolled in a clinical study using pemetrexed as the first-line intrathecal chemotherapy combined with radiotherapy. Kaplan-Meier method and Log rank test were used for survival analysis, and Cox regression model was used for influencing factor analysis. Results: The dose climbing study showed that the maximum tolerated dose of pemetrexed intrathecal chemotherapy was 10 mg per single dose, and the recommended dosing regimen was 10 mg once or twice a week. The incidence of adverse reactions was 10 cases, including hematological adverse reactions (7 cases), transaminase elevation (2 cases), nerve root reactions (5 cases), fatigue and weight loss (1 case). The incidence of serious adverse reactions was 4, including grade 4-5 poor hematology (2 cases), grade 4 nerve root irritation (2 cases), and grade 4 elevated aminotransferase (1 case). In the dose climbing study, 4 patients were effectively treated and 7 were disease controlled. The survival time was ranged from 0.3 to 14.0 months and a median survival time was 3.8 months. The clinical study of pemetrexed intrathecal chemotherapy combined with radiotherapy showed that the treatment mode of 10 mg pemetrexed intrathecal chemotherapy once a week combined with synchronous involved area radiotherapy 40 Gy/4 weeks had a high safety and reactivity. The incidence of major adverse reactions was 52.9% (18/34), including hematologic adverse reactions (13 cases), transaminase elevation (10 cases), and nerve root reactions (4 cases). In study 2, the response rate was 67.6% (23/34), the disease control rate was 73.5% (25/34), the overall survival time was ranged from 0.3 to 16.6 months, the median survival time was 5.5 months, and the 1-year survival rate was 21.6%. Clinical response, improvement of neurological dysfunction, completion of concurrent therapy and subsequent systemic therapy were associated with the overall survival (all P<0.05). Conclusions: Pemetrexed is suitable for the intrathecal chemotherapy with a high safety and efficacy. The recommended administration regimen was IP at 10 mg on the schedule of once or twice per week. Hematological toxicity is the main factor affecting the implementation of IP. Vitamin supplement can effectively control the occurrence of hematological toxicity.

Abstract
Objective: To understand the detection of group A rotavirus (RVA) in domestic sewage and its molecular epidemiological characteristics, and further explore the feasibility and necessity of RVA environmental surveillance. Methods: From 2016 to 2018, we collected domestic sewage samples monthly in Jinan city, and concentrated them via anion membrane adsorption-elution method. Then RNA extraction and RVA VP7 and VP4 coding region RT-PCR amplification were performed. After purification, TA cloning and sequencing, homology analysis and phylogenetic analysis were conducted on the obtained sequences. Results: RVA G gene was detected in 31 of the 36 sewage samples (86.1% detection rate); RVA P genotype was detected in 33 samples (91.7% detection rate). A total of 536 RVA sequences were obtained, of which 225 G-type sequences belonged to 6 genotypes, and the G9 accounted for 92.4% (208/225); 311 P-type sequences were obtained, which belonged to 4 genotypes. The dominant P[8] accounted for 50.1% (156/311), followed by P[4] with 41.8% (130/311). Phylogenetic analysis shows that there were multiple transmission chains circulating in the dominant genotypes G9 and P[8]. Conclusion: The genotype, homology, and phylogenetic characteristics of sequences obtained from domestic sewage in Jinan area were described, which further confirmeing that RVA environmental surveillance is not feasible but also necessary.

Abstract
Lung cancer is the most frequently diagnosed cancer and the most common cause of cancer mortality in China. Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancers. The mutation rate of epidermal growth factor receptor (EGFR) gene is relatively high, accounts for 32%~38% of all NSCLC. During the last decade, the application of EGFR specific tyrosine kinase inhibitors (TKI) significantly improved prognosis of NSCLC patients with sensitive EGFR mutations. Thus, the research and development of third generation EGFR-TKI have entered the period of rapid development. The fourth generation EGFR-TKI which targeting EGFR C797S has even begun clinical development in China. This review will discuss the clinical research and drug review of EGFR-TKI from the perspective of drug review.

Abstract
The data were drawn from injury hospitalization surveillance system in Shandong province. From 2012 to 2018, 164 cases of acute occupational poisoning were reported from five surveillance counties (cities, districts), accounting for 6.11% (164/2 683) of total accidental poisoning cases. The annual average reported incidence of acute occupational poisoning hospitalization was 1.15/100 000. The number of male cases was 3.3 times that of females (126 vs 38). The poisoning cases mainly occurred between January to May in a year and 5-7 AM within a day. Those cases were mainly caused by irritating gases (92 cases, 56.10%) and asphyxiating gases (53 cases, 32.32%), of which chlorine (71 cases) and carbon monoxide (50 cases) were the main reasons. The average hospitalization medical cost of acute occupational poisoning cases was 7 278.81 RMB per case.

Abstract
Objective: To evaluate the clinical and cardiac magnetic resonance (CMR) features of apical hypertrophic cardiomyopathy (ApHCM) patients complicating with left ventricular apical aneurysm (LVAA). Methods: CMR confirmed 25 ApHCM patients complicating with LVAA from January 2010 to December 2017 in Fuwai hospital were included in this study, and the baseline clinical data and CMR characteristics were retrospectively analyzed. There were 14 pure ApHCM (hypertrophy limited at the apical segments) complicating with LVAA patients and 11 mixed ApHCM (predominantly apical hypertrophy along with thickening of contiguous non-apical left ventricular region) with LVAA patients. Results: In this patient cohort,age of 84% (21/25) patients ranged between 20-70 years old, and 68% (17/25) were male. There were 68% (17/25) patients with complaint of chest distress symptom, 56% (14/25) with complaint of chest pain, 32% (8/25) with complaint of palpitation,16% (4/25) with complaint of dyspnea, and 12% (3/25) presented as syncope. ST-T segment changes of electrocardiogram were observed in all patients, and giant negative T waves were detected in 80% patients (20/25). The rate of missed diagnosis by echocardiography for detecting ApHCM and LVAA was 16% (4/25) and 68% (17/25), respectively. CMR showed discrete thin-walled dyskinetic or akinetic segment of the most distal portion of the left ventricular chamber in ApHCM patients with LVAA. Transmural late gadolinium enhancement of the aneurysmal rim was detected in 76% (19/25) patients, and the maximum transverse dimension of aneurysm was bigger in patients with transmural late gadolinium enhancement than in patients without transmural late gadolinium enhancement ((22.0±10.8)mm vs. (11.7±4.0) mm, P=0.033). Conclusion: ApHCM with LVAA patients have distinct cardiac clinical features, and CMR is the most useful tool for the accurate and objective evaluation of this disease.

Abstract
Objective: To investigate the dose-response relationship between hemoglobin concentration and preterm birth, during pregnancy. Methods: With Zhuang ethnicity, a total of 12 780 pregnant women and their infants that admitted to Wuming、Pingguo、Jingxi、Debao、Longan and Tiandong hospitals, were recruited, in Guangxi Zhuang Autonomous Region, from January 2015 to December 2017. Non-conditional logistic regression method was used to analyze the effect of anemia on preterm birth during pregnancy. Dose-response relationship between hemoglobin concentration and preterm birth was explored, using the restrictive cubic spline model. Results: After excluding 2 053 pregnant women with hypertension or aged 35 years and over, results from the non-conditional logistic regression analysis showed that the risk of preterm birth in the anemia group was 1.29 times (OR=1.29, 95%CI: 1.04-1.59, P=0.019) of the non-anemia group in the first trimester. Data from the restricted cubic sample showed that there appeared nonlinear "L" dose-response relationship between hemoglobin concentration and preterm birth in the first trimester and "U" shape in the third trimester (non-linearity test P<0.001). Conclusion: There appeared nonlinear dose-response relationship between the hemoglobin concentration and preterm birth, both in the first and third trimesters.

Abstract
Atom probe tomography (APT) coupling high-resolution transmission electron microscopy (HRTEM) was used to analyze the fraction and compositions of different nanoparticles in two-stage double peaks aging process of Al-Zn-Mg alloy. Al content is found to be closely related to the size of nanoparticles and it can be greater than ~ 50.0 at. % in the nanoparticle with the equivalent radius under ~ 3.0 nm. Correspondingly, Al content of the nanoparticle, with the equivalent radius over ~ 5.0 nm, is measured under ~ 40.0 at. %. Evolution from Guinier-Preston (G.P.) zone to η phase is a growing process where Mg and Zn atoms enter the nanoparticle, therefore rejecting Al atoms. G.P. zones can take up a number fraction of ~ 85.0 and ~ 22.7% of nanoparticles in the first and second peak-aged samples, respectively, and even in the over-aged (T73) sample, they can still be found. As aging time increases, fraction of η' phases monotonically rises to the peak value (~ 54.5%) in the second peak-aged state and then drops, which is significant for the second hardness peak and directly proves their function as the transitional medium. In T73 state, ~ 63.3% nanoparticles compose of η phases, which were measured to still contain ~ 10.2 to ~ 36.4 at. % Al atoms.

Abstract
OBJECTIVE The aim of this study was to prospectively investigate the incidence of ventilator associated events (VAEs) in intensive care units (ICUs) among adult patients, and to evaluate the correlation between VAEs and ventilator associated pneumonia (VAP). METHODS A prospective 3-month cohort study (January 2015 to March 2015) was carried out. VAEs were divided into three groups: with ventilator-associated condition (VAC), with infection related ventilator-associated complication (IVAC) and with possible VAP (PVAP). Sensitivity and specificity of VAEs were evaluated and compared to the traditional VAP. Kappa test was applied to judge the consistency of VAC and VAP. RESULTS During Jan. 2015 and Mar. 2015, 1 014 patients were admitted to 8 ICUs, with 7 977 patients per day. In total, 197 patients used the mechanical ventilation installation, with, a total number of 3 152 ventilator-days. Finally, 1 214 ventilation days in the VAC group and 1 938 ventilation days in the non-VAC group) that were available for final analysis. 46 VAC cases were identified including 22 classified as IVAC (14.59 and 6.98 per 1 000 ventilation days, respectively). Length of ICU stay and duration on mechanical ventilation for VAC patients were both significantly longer than those for non-VAC patients (P<0.05). Sensitivity and specificity of the VAC criteria for the detection of VAP were 36.92% and 83.33%, respectively. CONCLUSION The VAEs surveillance paradigms could be applied to monitor patients on the use of mechanical ventilation installation. However, sensitivity and specificity of VAC were under pool for the diagnosis of VAP. However, automatically surveillance programs was relied on the improvement of auto-information systems.

Abstract
BACKGROUND Emphysematous change on computed tomography (CT) during the stable phase of chronic obstructive pulmonary disease (COPD) is reported to correlate with COPD prognosis. Acute exacerbation of COPD (AECOPD) is associated with a high risk of mortality and a poor prognosis. AIMS This study aims to study the relationship between prognosis and emphysematous changes on CT during an AECOPD. METHODS Histories were recorded, and CT acquired for 106 patients who visited the emergency department for an AECOPD. Emphysematous change was quantified by measuring the percentage of low-attenuation areas (LAA%) in the entire lung on CT images with a threshold of -950 Hounsfield units. Other factors that could influence AECOPD prognosis were also recorded on admission and analysed. At follow ups conducted in 1 year, patient survival, the modified Medical Research Council (mMRC) Dyspnoea Scale, and performance status (PS) were evaluated, and a COPD Assessment Test (CAT) was completed. RESULTS The 1-year follow up was completed by 103 of 106 patients. The median LAA% was significantly higher in non-survivors (11%, n = 16) than in survivors (5.69%, n = 87) (P = 0.006) at the 1-year follow up. LAA% was significantly correlated with mMRC grade (r = 0.285, P = 0.008), PS (r = 0.397, P < 0.001) and CAT score (r = 0.27, P = 0.017) at the 3-month follow up, and with mMRC grade (r = 0.405, P < 0.001) and PS (r = 0.377, P < 0.001) at the 1-year follow up. LAA% > 7.5% was a significant predictor of 1-year mortality, higher mMRC and PS at the 3-month and 1-year follow ups, after adjustment for other prognostic predictors. CONCLUSION Obvious emphysematous changes on CT (LAA% > 7.5%) during an AECOPD predicts a poor prognosis independent of other known indicators.

Abstract
Since the 1960s, the marshes in the Sanjiang Plain, Northeast China, which are an important reservoir for dissolved carbon, have undergone long-term reclamation to farmland, resulting in elevated marsh loss and degradation on a large scale. This study compared the concentrations of dissolved carbon, as well as the chemical characteristics of dissolved organic carbon (DOC), in natural marshes, a degraded marsh, and drainage ditches sampled during the growing seasons between 2008 and 2010 to clarify the temporal-spatial variability of the dissolved carbon in the fluvial system influenced by the long-term reclamation. The results show that the average concentrations of total dissolved carbon (TDC) and DOC are considerably greater in the natural marshes than in the degraded marsh and drainage ditches. The average DOC concentration for the natural marshes, approximately 35.53 ± 5.15 mg L(-1), is approximately 2.39 times that in the degraded marsh (14.84 ± 4.21 mg L(-1)) and 2.77 times the average value in the ditches (12.84 ± 4.49 mg L(-1)). The dissolved inorganic carbon (DIC) exhibits increased trends in the drainage ditches compared with the natural marshes, whereas the hydrophobic fraction of DOC is present at lower concentrations in the degraded marsh and ditches. Fluorescence indices also indicate that the DOC in the degraded marsh and ditches has a simpler humification structure. In total, the long-term reclamation has led to great variability in the DOC concentration and chemical characteristics in the fluvial system. Changes in the DOC production potential and hydrological regimes due to sustained reclamation are deemed the predominant causes of this effect. The continuously decreased DOC concentration and high variability of DOC in the surface fluvial systems are inevitable if reclamation continues in the Sanjiang Plain. More importantly, the presence of tyrosine and tryptophan-like substances in the ditches indicates that there has been extensive agricultural organic pollution in the fluvial systems. This pollution could lead to more unexpected impacts on the downriver aquatic system. To avoid a destructive ecological crisis in the future, adjustment of the reclamation policy and agricultural management measures in the Sanjiang Plain is urgently needed.

Abstract
In hepatocellular carcinoma (HCC), Wnt/β-catenin, Ras/MAPK and PI3K/AKT signaling pathways form a complex network and play important roles during HCC genesis and development. To study their relationship and the influence on cell growth, the siRNA directed against β-catenin was transfected into HCC HepG2 cells. β-catenin mRNA and protein levels were measured respectively at various times by RT-PCR and Western blot. Furthermore, HCC cell growth was measured by MTT assay. Finally, MAPK family and Akt1 protein levels were also measured by Western blot. After the transfection, β-catenin mRNA levels were markedly inhibited at 24 h and increased gradually at 48, 72 and 96 h; β-catenin protein levels decreased gradually at 24, 48 and 72 h and slightly increased at 96 h. HCC cell growth was inhibited from 24-72 h, but this inhibition decreased at 96 h. ERK1/2 (p42/p44 MAPK), JNK/SAPK, p38 MAPK, and Akt1 protein levels showed no change following transfection, while their phosphorylated protein levels showed changes. Thus, siRNA directed against β-catenin markedly decreased β-catenin gene expression and inhibited cell growth. Wnt/β-catenin signaling pathway might regulate Ras/MAPK and PI3K/Akt signaling pathways through regulation of the phosphorylation state of ERK1/2, JNK/SAPK and Akt1 protein in HCC HepG2 cells. These pathways might compensate for the inhibitory effect of β-catenin, thereby affecting tumor cell growth and others downstream factors.

Abstract
Rubella virus (RUBV) infects cells via an acid-triggered membrane fusion process. RUBV virions contain two cysteine-rich glycoproteins, E2 and E1. The latter is believed to be involved in the membrane fusion. Using a recombinant plasmid containing RUBV E1 and E2, 11 of total 20 cysteines present in the ectodomain of wild type E1 were mutated to test their role in the fusion via the formation of disulfide bridges. The recombinant plasmids containing mutated E1 (Cys2-Cys20) or wild type (wt) E1 were expressed in BHK-21 cells. Their fusogenic and hemadsorption activities in addition to a potential of cell surface expression of E1 and E2 were assayed. The results showed that the fusogenic activity was lost in all tested mutants, while the hemadsorption activity and cell surface expression potential were affected differently in individual mutants. Since only the Cys5 and Cys8 mutations led to a reduction of both hemadsorption and cell surface expression, we assume that these mutations prevented the formation of the disulfide bridge, what led to a misfolding of E1 and consequently to a failure of recognition of E1 by E2. In conclusion, the disulfide bridges disrupted in all the tested mutants appear essential for the cell fusion, while only the disulfide bridge C(5)-C(8) seems to be crucial for the transport of E1 and E2 in the cell.

Abstract
BACKGROUND The objective was to describe the extent of passive smoking exposure and preventive actions against passive smoking in non-smoking pregnant women and to analyze factors associated with preventive actions. METHODS This was a cross-sectional survey on 1449 never-smoking pregnant women who made their first prenatal visit to the Women and Children's Hospital of Guangzhou, China during 1996-97. RESULTS 60.2% (95% Confidence Interval 57.7%-62.7%) of the never-smoking pregnant women had a husband who currently smoked. Women with smoking husbands (n=872) were more exposed to ETS than those with non-smoking husbands (n=577) at home (71% vs. 33%), in public places (77% vs. 66%) and at work (60% vs. 50% of working women), and they took less actions against passive smoking in public places. Women with better education and knowledge on smoking and passive smoking had stronger preventive actions. CONCLUSIONS Non-smoking pregnant women in China are often exposed to passive smoking and their preventive actions are weak. Passive smoking is an important obstetric and public health problem in developing countries and deserves urgent international attention.

Abstract
AIM To study the effect of (-)-stepholidine (SPD) on serum prolactin (PRL) level and elucidate its pharmacological action on dopamine D2 receptors. METHOD After i.p. administration of dopamine receptor agonist, antagonist, or SPD, the serum PRL levels were determined by radioimmunoassay. RESULTS SPD (24 mg.kg-1, i.p.) caused a rapid rise in serum PRL level, lasting more than 1 h. SPD 0.2-40 mg.kg-1 raised serum PRL level in a dose-dependent manner with ED50 of 3.7 mg.kg-1 (95% confidence limits, 2.6-4.3 mg.kg-1) and PRL maximal level of 448 +/- 64 micrograms.L-1. Pergolide 2 mg.kg-1 i.p. caused a decrease (P < 0.01 vs saline) of PRL level, which was partially attenuated by SPD of 5 mg.kg-1 and completely abolished by 10 mg.kg-1. CONCLUSION SPD is a dopamine D2 receptor antagonist.

Abstract
After i.p. administration of [14C]diphenyl ether (5 mg/kg) to rats, radioactivity was detected rapidly in all organs and tissues. After intragastric administration of [14C]diphenyl ether (10 mg/kg) to rats, unchanged diphenyl ether in the blood was at max. concn. within 15 h and decreased linearly with time, with a biological half-life of about 1.5 h. More than 90% of the intragastrically administered dose was excreted in urine and faeces within three days; greater than 80% dose was in the urine. From g.l.c. and mass-spectral data, it was shown that rats metabolized diphenyl ether to its 2-hydroxy, 4-hydroxy, 4,4'-dihydroxy, 4-methoxy-monohydroxy and 4-methoxy-dihydroxy derivatives.

Abstract
The metabolic disposition of 1-[14C]phenylcyclohexene ([14C]PC) was examined in rats after ip or iv drug administration. Radioactivity, which was accumulated by various organs, peaked within 30 min after ip administration of [14C]PC (0.21 mg/kg). A significant amount of this radioactivity was not extractable by repeated methanol extractions, indicating irreversible binding of [14C]PC metabolite(s) to tissue proteins. Following iv administration of [14C]PC (0.42 mg/kg), [14C]PC concentrations in blood declined biphasically with time; the blood elimination half-life of [14C]PC is 77 min. About 83% of the dose given was excreted in urine and feces within 54 hr of administration. About 35% of the dose was excreted in the bile in 1 hr. At least four [14C]PC metabolites were detected in the urine or bile. The bulk of the urinary radioactivity was composed of metabolites since less than 6% of [14C]PC given was excreted unchanged in the urine.
