Abstract
Breast cancer is a multifactorial heterogeneous disease and the leading cause of cancer-related deaths in women; its diagnosis and treatment require clinical sensitivity and a comprehensive disciplinary research approach. The expression of different receptors on tumor cells not only provides the basis for molecular typing of breast cancer but also has a decisive role in the diagnosis, treatment, and prognosis of breast cancer. To date, immunohistochemistry (IHC), which uses invasive histological sampling, has been extensively used in clinical practice to analyze the status of receptors and to make an accurate diagnosis of breast cancer. As an invasive assay, IHC can provide important biological information on tumors at a single point in time, but cannot predict future changes (due to treatment or tumor mutations) without additional invasive procedures. These issues highlight the need to develop a non-invasive method for predicting receptor status. The emerging field of radiomics may offer a non-invasive approach to identification of receptor status without requiring biopsy. In this paper, we present a review of the latest research results in radiomics for predicting the status of breast cancer receptors, with potential important clinical applications.

Abstract
OBJECTIVES The efficacy of electroconvulsive therapy (ECT) in treating mood disorders (MDs) is hypothesized to be mediated by the induction of neurotrophic factors (denoted "angioneurins") that trigger neuronal plasticity. This study aimed to assess the effects of ECT on serum angioneurin levels in patients with MD. METHODS A total of 110 patients with MDs including 30 with unipolar depression, 25 with bipolar depression (BD), 55 with bipolar mania (BM), and 50 healthy controls were included in the study. Patients were subdivided into two groups: those who received ECT + medication (12 ECT sessions) and those who received only medication (no-ECT). Depressive and manic symptom assessments and measurements of vascular endothelial growth factor (VEGF), fibroblast growth factor-2, nerve growth factor (NGF), and insulin-like growth factor-1 levels in blood samples were performed at baseline and week 8. RESULTS Patients in the ECT group, specifically those with BD and BM, had significantly increased levels of VEGF compared to their baseline VEGF levels (p = 0.002). No significant changes in angioneurin levels were observed in the no-ECT group. Serum NGF levels were significantly associated with a reduction in depressive symptoms. Angioneurin levels were not associated with manic symptom reduction. CONCLUSIONS This study hints that ECT may increase VEGF levels with angiogenic mechanisms that amplify NGF signaling to promote neurogenesis. It may also contribute to changes in brain function and emotional regulation. However, further animal experiments and clinical validation are needed.

Abstract
Although the phenomenon of attenuated niacin response (ANR) has been widely replicated in some patients with first-episode psychosis (FEP), its relevance to the negative symptoms (NS) of psychosis remains unclear. Total of 240 patients with drug-naïve FEP and 101 healthy controls (HCs) were recruited, and 209 were followed up for 1 year. Psychotic symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS), and niacin-induced responses were measured using laser Doppler flowmetry. We calculated the log-transform EC50 [concentration of methyl nicotinate required to elicit a half-maximal blood flow (MBF) response] and MBF values. Core-NS was generated by factor analysis of the PANSS-NS subscale and cluster analysis to produce subtypes. Significant differences were found in the log10 (EC50) values between the FEP and HC groups (p < 0.001), supporting the ANR in patients with FEP. A higher NS severity was found in the ANR subgroup than that in other patients. Factor analysis determined that a two-dimensional model included core NS and rigidity of thinking. The log10 (EC50) value was significantly associated with only the core NS. Cluster analysis revealed three subtypes-36.7% (cluster-1, n = 88), 16.7% (cluster-2, n = 40), and 46.7% (cluster-3, n = 112). Cluster-2 characterized by extensive NS appeared to have a more remarkable ANR and less symptomatic improvement than those with other clusters during follow-up. No significant changes were found in the niacin response trajectories between the baseline and follow-up. Our findings indicate a significant correlation between ANR and core NS in patients with FEP. ANR may be a potential biomarker for certain subtypes with NS-dominated characteristics and poor symptomatic remission.

Abstract
Objective: To analyze genioglossus (GG) activation responses to the negative pressure of upper airway cavity during awake and different sleep stages in patients with different obstructive sleep apnea (OSA) graduation. Methods: This prospective cohort study started from August 2019 to January 2021, recruited 42 male OSA patients aged from 21 to 59 (38.77±8.42) years. After completing whole night polysomnography (PSG) and upper airway CT, each subject underwent drug-induced sleep with simultaneous monitoring of genioglossal electromyography (GGEMG) and pressure of epiglottis (Pepi). Subjects were divided into three groups of mild OSA(7 males), moderate OSA(12 males), and severe OSA(23 males). The differences in upper airway CT measurements, parameters of GGEMG and Pepi during awake and induced sleep were compared. Statistical analysis was conducted by SPSS 21.0. Results: There was no significant difference in the GGEMG parameters between the mild and moderate groups. In wakefulness, the peak phasic GGEMG of the severe group was higher than the mild group (t=1.249, P=0.025), with no statistically difference in the corresponding Pepi. In the sleep onset, the GGEMG parameters and Pepi in severe group were higher than the other two groups. Linear regression analysis of the maximum GGEMG and maximum Pepi at the end of obstructive apnea (OA) in all moderate plus severe patients (n=35) was shown nonlinear correlation (r=0.28, P=0.694). The airway length of the glossopharyngeal cavity was linearly correlated with the maximum Pepi of OA (r=0.468, R2=0.219, P=0.005). Conclusions: The individual difference of GG activation in OSA patients is related to the severity of the disease (frequency of respiratory events) and negative pressure stimulation. In moderate and severe OSA patients, GG activity is not in harmony with the corresponding negative pressure stimulation, which may be one of the mechanisms leading to the aggravation of OSA.

Abstract
Introduction Numerous studies have established the roles of inflammation and angioneurins in the pathogenesis of schizophrenia (SCZ). This study aimed to compare the serum levels of tumour necrosis factor (TNF)-α and vascular endothelial growth factor (VEGF) in patients at clinical high risk (CHR) for psychosis or SCZ at baseline and one year after treatment. Methods A total of 289 CHR participants from the Shanghai At Risk for Psychosis Extended Program (SHARP) were tracked for a year. They were divided into two and four subtypes based on symptom severity according to the Structured Interview for Prodromal Syndromes (SIPS) and received standard medical care. At baseline and one-year follow-up, TNF-α and VEGF were detected using enzyme-linked immunosorbent assay, and pathological features were assessed using the Global Assessment of Function (GAF) score. Results Baseline TNF-α levels did not differ significantly, while VEGF levels were lower in patients with more severe symptoms. VEGF showed a negative correlation with negative features, both overall (r = -0.212, p = 0.010) and in the subgroup with higher positive scores (r = -0.370, p = 0.005). TNF-α was positively correlated with negative symptoms in the subgroup with higher negative scores (r = 0.352, p = 0.002). A three-way multivariate analysis of variance demonstrated that participants in Subtype 1 of positive or negative symptoms performed better than those in Subtype 2, with significant main effects and interactions of group and both cytokines. Discussion TNF-α and VEGF levels are higher and lower, respectively, in CHR patients with more severe clinical symptoms, particularly negative symptoms, which point to a worsening inflammatory and vascular status in the brain.

Abstract
Objective: Attenuated niacin responses and changes in cytokine levels have been reported in schizophrenia. However, prior studies have typically focused on schizophrenia, and little is known about the association between niacin response and inflammatory imbalance in clinically high-risk psychosis (CHR). This study aimed to assess the niacin response to inflammatory imbalance for association with conversion to psychosis within 2 years. Methods: A prospective case-control study was performed to assess the niacin response and interleukin (IL)-1β, IL-2, IL-6, IL-8, IL-10, and tumor necrosis factor-α levels in 60 CHR individuals and 60 age- and sex-matched healthy controls (HC) from May 2019 to December 2021. Participants with CHR were identified using the Structured Interview for Prodromal Syndromes. The niacin-induced responses were measured using laser Doppler flowmetry. From the dose-response curves, the log-transferred concentration of methylnicotinate required to elicit a half-maximal blood flow response (LogEC50) and maximal minus minimal blood flow response (Span) values were calculated for each subject. Serum cytokine levels were measured using enzyme-linked immunosorbent assay. Individuals with CHR were then divided into converters (CHR-C, n = 15) and non-converters (CHR-NC, n = 45) to psychosis based on their 2-year follow-up clinical status. Results: The CHR group exhibited significantly higher LogEC50 (t = 3.650, P < .001) and Span (t = 2.657, P = .009) values than the HC group. The CHR-C group exhibited a significantly shorter Span (t = 4.027, P < .001) than the CHR-NC group. The LogEC50 showed a trend toward significance (t = 1.875, P = .066). None of the cytokine levels were significant. The conversion outcome can therefore be predicted by applying LogEC50 (P = .049) and Span (P < .001). The regression model with variables of LogEC50, Span, family history, and scores of positive symptoms showed good discrimination of subsequent conversion to psychosis and achieved a classification accuracy of 91.7%. The decreased LogEC50 in the CHR-C group was significantly correlated with the increased IL-1β/IL-10 ratio (Spearman ρ = -0.600, P = .018), but this correlation was nonsignificant in the CHR-NC group. Conclusions: Our findings indicate a significant association between niacin response and psychosis conversion outcomes in individuals with CHR. Compared with peripheral inflammatory cytokines, the niacin response can better predict conversion, although there may be an intersection between the two in biological mechanisms.

Abstract
Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

Abstract
INTRODUCTION Immune alterations are associated with the progression of psychosis. However, there are few studies designed to longitudinally measure inflammatory biomarkers during psychotic episodes. We aimed to assess changes in biomarkers from the prodromal phase to psychotic episodes in individuals with clinical high risk (CHR) of psychosis and compare converters and non-converters to psychosis as well as healthy controls (HCs). METHODS We enrolled 394 individuals with CHR and 100 HCs. A total of 263 individuals with CHR completed the 1-year follow-up, and 47 had converted to psychosis. Interleukin (IL)-1β, 2, 6, 8, 10, tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor levels were measured at baseline and 1 year after completion of the clinical assessment. RESULTS The baseline serum levels of IL-10, IL-2, and IL-6 were significantly lower in the conversion group than in the non-conversion group (IL-10, p = 0.010; IL-2, p = 0.023; IL-6, p = 0.012) and HC (IL-6: p = 0.034). Self-controlled comparisons showed that IL-2 changed significantly (p = 0.028), and IL-6 levels tended toward significance (p = 0.088) in the conversion group. In the non-conversion group, serum levels of TNF-α (p = 0.017) and VEGF (p = 0.037) changed significantly. Repeated measures analysis of variance revealed a significant time effect related to TNF-α (F = 4.502, p = 0.037, effect size (η2) = 0.051), a group effect related to IL-1β (F = 4.590, p = 0.036, η2 = 0.062), and IL-2 (F = 7.521, p = 0.011, η2 = 0.212), but no time × group effect. DISCUSSION Alterations in the serum levels of inflammatory cytokines were found to precede the first episode of psychosis in the CHR population, particularly for those who later converted to psychosis. Longitudinal analysis supports the varied roles of cytokines in individuals with CHR with later psychotic conversion or non-conversion outcomes.

Abstract
Previous studies have revealed that the imbalance between Th1 cytokines and Th2 cytokines plays a role in disturbance of cellular responses in the brain during psychosis. Cross-sectional studies have implied that inflammatory cytokine changes emerge in early psychosis, even at the at-risk stage. This study aimed to test the hypothesis that inflammatory imbalance in clinical high-risk (CHR) individuals is associated with an increased risk of future psychosis. A prospective case-control study was performed to assess the Th1(interleukin (IL)-1β)/Th2(IL-6) balance in 84 CHR individuals and 65 age- and sex-matched healthy controls (HC). Serum IL-1β and IL-6 levels were measured by enzyme-linked immunosorbent assay at baseline and 1-year after the completion of the clinical assessment. Sixteen (19.0%) CHR participants converted to full psychosis during the 1-year follow-up period. At baseline, serum IL-1β level was significantly lower in the CHR-converter group - resulting in decreased IL-1β/IL-6 ratios - compared to those of the CHR-non-converter and HC groups. At the 1-year follow-up, IL-1β level had decreased, and IL-1β/IL-6 ratios had decreased in the CHR-non-converter group, such that these were comparable to values in the CHR-converter at this time point. Analysis of the changes in IL-1β/IL-6 ratio between the baseline and 1-year follow-up measurements identified different trajectories in the CHR-converter and CHR-non-converter groups. Our findings demonstrate that a specific pattern of Th1/Th2 imbalance (decreased IL-1β/IL-6 ratios with lower serum IL-1β level) is associated with an increased risk of developing psychosis. Such specific pattern has potential for predicting conversion outcomes and selecting a distinct subgroup of CHR with immune-imbalanced-phenotype, that relevance in precise prevention.

Abstract
Background Leptomeningeal metastases (LM) are more frequent in non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. Due to limited access to leptomeningeal lesions, the purpose of this study was to explore the potential role of cerebrospinal fluid (CSF) as a source of liquid biopsy in patients with LM. Patients and methods Primary tumor, CSF, and plasma in NSCLC with LM were tested by next-generation sequencing. In total, 45 patients with suspected LM underwent lumbar puncture, and those with EGFR mutations diagnosed with LM were enrolled. Results A total of 28 patients were enrolled in this cohort; CSF and plasma were available in 26 patients, respectively. Driver genes were detected in 100% (26/26), 84.6% (22/26), and 73.1% (19/26) of samples comprising CSF cell-free DNA (cfDNA), CSF precipitates, and plasma, respectively; 92.3% (24/26) of patients had much higher allele fractions in CSF cfDNA than the other two media. Unique genetic profiles were captured in CSF cfDNA compared with those in plasma and primary tissue. Multiple copy number variations (CNVs) were mainly identified in CSF cfDNA, and MET copy number gain identified in 47.8% (11/23) of patients was the most frequent one, while other CNVs included ERBB2, KRAS, ALK, and MYC. Moreover, loss of heterozygosity (LOH) of TP53 was identified in 73.1% (19/26) CSF cfDNA, which was much higher than that in plasma (2/26, 7.7%; P < 0.001). There was a trend towards a higher frequency of concomitant resistance mutations in patients with TP53 LOH than those without (70.6% versus 33.3%; P = 0.162). EGFR T790M was identified in CSF cfDNA of 30.4% (7/23) of patients who experienced TKI progression. Conclusion CSF cfDNA could reveal the unique genetic profiles of LM and should be considered as the most representative liquid biopsy medium for LM in EGFR-mutant NSCLC.

Abstract
Objective: To compare the changes of genioglossus electromyography (GGEMG) with and without continuous positive airway pressure (CPAP) ventilation in moderate to severe obstructive sleep apnea (OSA) patients. Methods: Each of subjects, including male snorers and non-snorers, underwent polysomnography (PSG) with synchronous GGEMG recording with intra-oral bipolar silver ball electrodes at the Sleep Center of Beijing Tsinghua Changgung Hospital from August 2016 to Sepember 2017. Manual CPAP pressure titration and with GGEMG were performed in patients diagnosed moderate to severe OSA. T-test was used to compare the changes of GGEMG in OSA group (n=12, AHI (65.90+23.67) events/h) and control group (n=6, AHI(2.30+1.93) events/h) before and after CPAP treatment. Results: Variables of GGEMG (including tonic, peak and phasic GGEMG) were higher in OSA group than in control group during both wakefulness and non rapid eye movement(NREM) sleep. However, with CPAP treatment, the GGEMG variables were significantly decreased in OSA group during NREM sleep(tonic GGEMG: 1.23%±0.73% vs. 2.54%±1.12%, t=4.024, P=0.002; peak GGEMG: 12.37%±13.19% vs. 26.98%±15.52%, t=2.795, P=0.017; phasic GGEMG: 3.81%±2.47% vs. 8.82%±3.84%, t=5.113, P<0.001). Conclusions: CPAP treatment can eliminate respiratory events and maintain airway patency. It is helpful to normalize the excessive GGEMG response in OSA patients during sleep, which has therapeutic significance to alleviate and prevent genioglossal neuromuscular lesions.

Abstract
Objective: To compare the parameters of polysomnography (PSG) in sleep structure and respiratory events between dexmedetomidine-induced sleep and natural sleep. Methods: From April 2016 to September 2018, a total of 44 patients with obstructive sleep apnea (OSA) and 3 patients with simple snoring completed PSG monitor both in natural sleep and dexmedetomidine-induced sleep in Department of Otorhinolaryngology Head and Neck Surgery, Beijing Tsinghua Changgung Hospital. The PSG parameters were statistically analysed with SPSS 22.0 software. Results: The average dose of dexmedetomidine was (104.60±27.93) μg, and there was no significant difference between the induced-sleep efficiency and the natural sleep efficiency (82.14%±16.66% vs. 86.50%±9.18%, t=-1.559, P>0.05). There was no rapid eye movement(REM) stages in all 47 subjects and only 1 case of them had non-rapid eye movement(NREM) stage 3 in induced sleep. The percentage of NREM1 in total sleep time was statistically different between the two groups (42.10%±26.71% vs. 17.47%±11.68%, t=5.997, P<0.001),but there was no significant difference in the percentage of NREM2 in total sleep time between the two groups (56.96%±26.0% vs. 62.95%±9.03%, t=-1.521, P=0.135). About respiratory events, there were significant differences in apnea hypopnea index ((46.29±20.23)/h vs. (39.67±25.41)/h), obstructive apnea index (25.20[10.50,45.40]/h vs. 16.20[3.30,35.20]/h) between induced-sleep and natural sleep (t=2.297, Z=-3.008, all P<0.05), these difference were more significant in mild-to-moderate OSA. There were no statistically significant differences in central apnea index (0.00[0.00,2.80]/h vs. 0.40[0.10,1.20]/h), mixed apnea index (0.00[0.00,6.20]/h vs. 0.00[0.00,3.40]/h, hypopnea index (4.20[0.00,3.30]/h vs. 12.00[5.20,17.40]/h), Z=-0.110,-0.508,-1.544, all P>0.05). There were statistical differences in the lowest oxygen saturation (84.77%±7. 59% vs. 80.21%±11.62%, t=2.558, P=0.014). Conclusions: There is no significant difference in sleep efficiency and NREM2 between dexmedetomidine induced sleep and natural sleep.NREM3 sleep is rare induced, but REM sleep is none of all. And dexmedetomidine induced sleep may aggravate obstructive sleep apnea, but not central apnea.

Abstract
Objective: To investigate the effect of genioglossus (GG) activation at sleep onset on the outcome of velopharyngeal surgery in obstructive sleep apnea hypopnea syndrome (OSAHS) patients. Methods: Thirty-five patients between April 2014 and February 2015 in Beijing Tongren Hospital with OSAHS underwent overnight polysomnography with synchronous genioglossus electromyography (GGEMG) using intraoral electrodes. The upper airway (UA) anatomy was evaluated by three-dimensional computer tomography (3D-CT) in OSAHS patients. Then, all of the patients received velopharyngeal surgery, including revised uvulopalatopharyngoplasty (UPPP) with uvula preservation or UPPP combined transpalatal advancement pharyngoplasty. All patients were followed-up using polysomnography 3-6 months after surgery. T-test or Wilcoxon test were used to compare the variables between groups, and Spearman correlation analysis was used to test the correlation between parameters. Results: Thirty-five patients received velopharyngeal surgery. Twenty-two patients (62.86%) were responders, and 13 patients (37.14%) were non-responders. Responders had a higher mean GGEMG during sleep onset (15.31±3.74 vs. 9.92±2.93, t=4.504, P=0.001). The decreased AHI was significantly positively related to the sleep onset mean GGEMG (r=0.541, P=0.004) and the change in GGEMG (r=0.422, P=0.028). The decreased AHI was significantly negatively related to the minimal cross sectional airway area (mCSA,ρ=0.629,P=0.000) and the minimal lateral airway dimension (mLAT, ρ=0.484, P=0.009) at velopharynx. Conclusions: The outcome of velopharyngeal surgery was affected by the mean GGEMG during sleep onset. We speculated that the patient with higher GGEMG at sleep onset and narrower velopharynx were more suitable candidates for velopharyngeal surgery.

Abstract
Objective: To determine the objective effects of adenotonsillectomy on pediatric obstructive sleep apnea hypopnea syndrome (OSAHS) through analyzing the polysomnography (PSG) results between pre and post-operation. Methods: A total of 56 pediatric OSAHS patients were included who underwent adenoidectomy or/and tonsillectomy and completed PSG follow-up from January 1, 2017 to March 31, 2018. All the pediatric patients who underwent adenoidectomy or/and tonsillectomy during the research period were arranged to take a preoperative PSG study. Patients who were diagnosed OSAHS would be encouraged to complete a follow-up PSG study ranged from1 to 3 months after surgery. The parameters of respiration and sleep architecture of PSG were compared and analyzed. The paired student t test was used to compare preoperative and postoperative mean values. The unpaired student t test was used to compare quantitative variables among different groups. The rank sum test was used if the data were abnormal distribution. Results: Totally 238 patients completed preoperative PSG study, 62 patients were diagnosed as pediatric OSAHS, 56 eligible patients finished post-operative PSG. Hypopnea was the majority in all type of respiratory events in 56.45% (35/62) subjects, while central apnea as the majority in 29.03% (18/62) subjects who can also get significant CAI decrease after surgery. However, obstructive apnea as the majority only exist in 14.52% (9/62) subjects. The short-term cure rate of pediatric OSAHS was 85.71% (48/56). The postoperative AHI, MAI, CAI, HI, ODI, LoSpO(2), percentage of stage I sleep and arousal index were significantly decreased, however, the OAI was no statistical decrease. The percentage of stage Ⅱ and rapid eye movement (REM) sleep were significantly increased, while no significant change in percentage of slow wave sleep and sleep efficiency(t=2.32, P=0.017). Conclusions: Pediatric OSAHS manifest different characteristics of respiratory events from that of adults. Adenotonsillectomy can significant decrease respiratory events and improve sleep architecture, however, there are still some patients who can't be completely relieved with adenotonsillectomy.

Abstract
Objective: To investigate the effect of human antigen R on lysosomal acidification during autophagy in mouse cardiomyocytes cultured in vitro. Methods: The hearts of 20 C57BL/6 mice aged 1-2 days no matter male or female were isolated to culture primary cardiomyocytes which were used in the following experiments. (1) The cells were divided into 5 groups according to the random number table (the same grouping method below), i. e., normal control group and sugar-free serum-free 0.5, 1.0, 3.0, and 6.0 h groups. The cells in normal control group were routinely cultured for 54.0 h with Dulbecco's modified Eagle medium/nutrient mixture F12 (DMEM/F12) medium (the same regular culture condition below), and the cells in sugar-free serum-free 0.5, 1.0, 3.0, and 6.0 h groups were firstly regularly cultured for 53.5, 53.0, 51.0, 48.0 h and then cultured with replaced sugar-free serum-free medium for 0.5, 1.0, 3.0, and 6.0 h, respectively. The protein expressions of microtubule-associated protein 1 light chain 3 Ⅱ (LC3Ⅱ), autophagy-related protein 5, and adenosine triphosphatase V1 region E1 subunit (ATP6V1E1) were detected by Western blotting. (2) The cells were divided into normal control group and sugar-free serum-free 3.0 h group. The cells in corresponding groups were treated the same as those in experiment (1), and the cell lysosomal acidification level was observed and detected under a laser scanning confocal microscope. (3) Two batches of cells were grouped and treated the same as those in experiment (1). The protein expression of human antigen R in the whole protein of cells of one batch and its protein expression in the cytoplasm and nucleus protein of cells of the other batch were detected by Western blotting. (4) The cells were divided into normal control group, simple control small interfering RNA (siRNA) group, simple human antigen R-siRNA1 (HuR-siRNA1) group, simple HuR-siRNA2 group, sugar-free serum-free 3.0 h group, sugar-free serum-free+ control siRNA group, sugar-free serum-free+ HuR-siRNA1 group, and sugar-free serum-free+ HuR-siRNA2 group. After 48 hours of regular culture, the cells in simple control siRNA group and sugar-free serum-free+ control siRNA group were transfected with negative control siRNA for 6 h, the cells in simple HuR-siRNA1 group and sugar-free serum-free+ HuR-siRNA1 group were transfected with HuR-siRNA1 for 6 h, and the cells in simple HuR-siRNA2 group and sugar-free serum-free+ HuR-siRNA2 group were transfected with HuR-siRNA2 for 6 h. Hereafter, the cells in these 8 groups were continuously cultured for 48 h with regular conditon, and then the cells in normal control group and each simple siRNA-treated group were replaced with DMEM/F12 medium, the cells in the other groups were replaced with sugar-free serum-free medium, and they were cultured for 3 h. The protein expression of human antigen R in the whole protein of cells was detected by Western blotting. (5) Two batches of cells were divided into sugar-free serum-free+ control siRNA group and sugar-free serum-free+ HuR-siRNA1 group, and the cells in corresponding groups were treated the same as those in experiment (4). The distribution and expression of human antigen R in the cells of one batch were observed and detected by immunofluorescence method, and the lysosomal acidification level in the cells of the other batch was observed and detected under a laser scanning confocal microscope. (6) Three batches of cells were divided into sugar-free serum-free 3.0 h group, sugar-free serum-free+ control siRNA group, sugar-free serum-free+ HuR-siRNA1 group, and sugar-free serum-free+ HuR-siRNA2 group, and the cells in corresponding groups were treated the same as those in experiment (4). The protein expressions of cathepsin D in the whole protein of cells of one batch, human antigen R in the cytoplasm protein of cells of one batch, and ATP6V1E1 in the whole protein of cells of the other batch were detected by Western blotting. (7) The cells were divided into normal control group, sugar-free serum-free 3.0 h group, sugar-free serum-free+ control siRNA group, and sugar-free serum-free+ HuR-siRNA1 group, and the cells in corresponding groups were treated the same as those in experiment (4). The mRNA expression of ATP6V1E1 in cells was detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction. The sample number of each experiment was 3. Data were processed with independent data t test, one-way analysis of variance, least significant difference t test, and Bonferroni correction.

Abstract
Objective: To investigate influence of nicotinic acid adenine dinucleotide phosphate (NAADP) on autophagy in hypoxic cardiomyocytes of rats and its mechanism. Methods: Five neonatal Sprague-Dawley rats were collected and sacrificed to harvest the hearts, and primary cardiomyocytes were separated for the following experiments. (1) Primary cardiomyocytes were collected and divided into normoxia group, hypoxia 9 h group, and hypoxia 9 h+ NAADP group according to random number table, with 5 wells in each group. Cells in normoxia group were cultured routinely in the constant temperature incubator at 37 ℃ for 9 hours. Cells in hypoxia 9 h group and hypoxia 9 h+ NAADP group were cultured in hypoxic incubator with volume fraction 94% nitrogen, 5% carbon dioxide, and 1% oxygen for 9 hours. Before hypoxia, cells in hypoxia 9 h+ NAADP group were dealt with final amount-of-substance concentration 10 μmol/L NAADP. Cell counting kit 8 was used to measure cell viability. (2) Primary cardiomyocytes were collected and divided into normoxia group, hypoxia 9 h group, hypoxia 9 h+ NAADP group, hypoxia 9 h+ tran-Ned-19 group, and hypoxia 9 h+ trans-Ned-19+ NAADP group according to the random number table, with 2 wells in each group. Cells in normoxia group were cultured routinely in the constant temperature incubator at 37 ℃ for 9 hours. And cells in the other 4 groups were cultured in hypoxic incubator as that in experiment (1) Before hypoxia, cells in hypoxia 9 h+ NAADP group were dealt with amount-of-substance concentration 10 μmol/L NAADP, cells in hypoxia 9 h+ tran-Ned-19 group were dealt with amount-of-substance concentration 1 μmol/L trans-Ned-19, and cells in hypoxia 9 h+ trans-Ned-19 + NAADP group were dealt with amount-of-substance concentration 10 μmol/L NAADP and 1 μmol/L trans-Ned-19. Protein expressions of microtubule associated protein 1 light chain 3-Ⅱ and P62 were detected by Western blotting. (3) Primary cardiomyocytes were collected and grouped as those in experiment (1). The lysosomal acidity was determined by immunofluorescence method. Data were processed with one-way analysis of variance and least-significant difference test. Results: (1) The cell viability in normoxia group was 1.114±0.024, which was significantly higher than 0.685±0.079 of cells in hypoxia 9 h group (P<0.01). The cell viability of hypoxia 9 h+ NAADP group was 0.886±0.061, which was obviously higher than that of cells in hypoxia 9 h group (P<0.05). (2) Expressions of microtubule-associated protein 1 light chain 3-Ⅱ and P62 of cells in hypoxia 9 h group were significantly higher than those of cells in normoxia group (P<0.01). Compared with those in hypoxia 9 h group, expression of P62 in hypoxia 9 h+ NAADP group was significantly decreased (P<0.01), while expression of microtubule-associated protein 1 light chain 3-Ⅱ did not change significantly (P>0.05). There were no significantly statistical difference in expressions of microtubule-associated protein 1 light chain 3-Ⅱ and P62 between hypoxia 9 h group and hypoxia 9 h+ trans-Ned-19 group (P>0.05). Compared with those of cells in hypoxia 9 h+ NAADP group, expression of P62 of cells in hypoxia 9 h+ trans-Ned-19+ NAADP group was obviously increased (P<0.01), while expression of microtubule-associated protein 1 light chain 3-Ⅱ did not change significantly (P>0.05). (3) The intensity of green fluorescence of cells in normoxia group was strong and co-localized well with red fluorescence, and internal environment of lysosome was with stronger acidity. The intensity of green fluorescence in cells of hypoxia 9 h group was significantly lower than that of cells in normoxia group, and acidity of internal environment of lysosome was weakened. The intensity of green fluorescence and acidity of internal environment of lysosome in hypoxia 9 h+ NAADP were significantly stronger than those of cells in hypoxia 9 h group, but significantly lower than those of cells in normoxia group. Conclusions: NAADP can improve myocardial cell viability through acidifying internal environment of lysosome of cardiomyocyte after hypoxia, promoting degradation of autophagosomes, reducing autophagic lysosomal accumulation, and repairing damaged autophagic flow.

Abstract
Objective: To explore the effects of decline of pH value on cardiomyocyte viability of rats, and to analyze the possible mechanism. Methods: Hearts of five newborn Sprague-Dawley rats were isolated, and then primary cardiomyocytes were cultured and used in the following experiments. (1) The primary cardiomyocytes were divided into pH 7.4+ 6 h, pH 7.0+ 6 h, pH 6.5+ 6 h, pH 6.0+ 6 h, pH 6.5+ 1 h, and pH 6.5+ 3 h groups according to the random number table, with 4 wells in each group. After being routinely cultured for 48 h (similarly hereinafter), cells in pH 7.4+ 6 h, pH 7.0+ 6 h, pH 6.5+ 6 h, and pH 6.0+ 6 h groups were cultured with pH 7.4, pH 7.0, pH 6.5, and pH 6.0 DMEM-F12 medium (similarly hereinafter), respectively, and then they were cultured for 6 h. Cells in pH 6.5+ 1 h and pH 6.5+ 3 h groups were cultured with pH 6.5 medium, and then they were cultured for 1 h and 3 h, respectively. Viability of cells was detected by methyl-thiazolyl-tetrazolium (MTT) method. (2) The primary cardiomyocytes were divided into pH 7.4, pH 6.5, and pH 6.5+ taxol groups according to the random number table, with 2 wells in each group. Cells in pH 7.4 group were cultured with pH 7.4 medium, while cells in pH 6.5 and pH 6.5+ taxol groups were cultured with pH 6.5 medium. Cells in pH 6.5+ taxol group were added with taxol of a final molarity of 0.2 μmol/L in addition, and then they were cultured for 6 h. Morphology and density of microtubule of cells was detected by immunofluorescence assay. (3) The primary cardiomyocytes were grouped and treated as in experiment (2), with 2 wells in each group. The expressions of polymerized microtubulin and free microtubulin were determined with Western blotting. (4) The primary cardiomyocytes were grouped and treated as in experiment (2), with 4 wells in each group. Viability of cells after treated with taxol was detected by MTT method. Data were processed with one-way analysis of variance and LSD-t test. Results: (1) The viability of cells in pH 7.4+ 6 h, pH 7.0+ 6 h, pH 6.5+ 6 h, pH 6.0+ 6 h, pH 6.5+ 1 h, and pH 6.5+ 3 h groups were 1.00±0.08, 0.90±0.08, 0.85±0.06, 0.83±0.04, 0.91±0.10, and 0.89±0.10, respectively. Compared with that in pH 7.4+ 6 h group, viability of cells in pH 7.0+ 6 h, pH 6.5+ 6 h, pH 6.0+ 6 h, pH 6.5+ 1 h, and pH 6.5+ 3 h groups were all decreased in different degrees (t=2.476, 4.002, 4.996, 2.168, 2.400, P<0.05). (2) Microtubules of cells in pH 7.4 group were radially distributed around the nucleus with clear tubular structure. Compared with that in pH 7.4 group, the skeleton of microtubules of cells in pH 6.5 group was obviously damaged, with broken structure of microtubule and reduced density. Compared with that in pH 6.5 group, the damage degree of microtubules of cells in pH 6.5+ taxol group was obviously alleviated, and the structure of microtubules basically returned to normal. (3) Compared with that in pH 7.4 group, the expression of free microtubulin of cells in pH 6.5 group was significantly increased (t=3.030, P<0.05), while the expression of polymerized microtubulin of cells was significantly decreased (t=8.604, P<0.05). Compared with that in pH 6.5 group, the expression of free microtubulin of cells in pH 6.5+ taxol group was significantly decreased (t=4.559, P<0.05), while the expression of polymerized microtubulin of cells was significantly increased (t=5.472, P<0.05). (4) Viability of cells in pH 7.4, pH 6.5, and pH 6.5+ taxol groups were 1.00±0.10, 0.83±0.04, and 0.93±0.10, respectively. Compared with that in pH 7.4 group, the viability of cells in pH 6.5 group was obviously declined (t=4.412, P<0.05). Compared with that in pH 6.5 group, the viability of cells in pH 6.5+ taxol group was obviously increased (t=2.461, P<0.05). Conclusions: The decline of pH value reduces the viability of cardiomyocytes of rats through destroying the skeleton of microtubule. Stabilizing microtubule skeleton can significantly reduce acidic treatment-induced damage and ameliorate cardiomyocyte viability.

Abstract
To explore the efficacy of sorafenib combined with chemotherapy and donor lymphocyte infusion (DLI) in patients with FLT3-positive acute myeloid leukemia (AML) relapsed after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Of the 14 patients relapsed after allo-HSCT, 9 achieved complete remission after salvage therapy of sorafenib combined with chemotherapy and DLI, 6 with complete molecular remission, 2 with partial remission, and 3 with no response. With a median follow up of 220 (range, 30-1 782) days after post-transplantation relapse, 7 patients were still alive and 7 died. Salvage therapy of sorafenib combined with chemotherapy and DLI shows a decent therapeutic effect for FLT3-positive AML relapsed after allo-HSCT.

Abstract
The hypertrophy of adenoid and tonsillar is the most common cause of obstructive sleep apnea hypopnea syndrome(OSAHS) in children, which require early diagnosis and standardized treatment to improve behavior, attention and cognitive abilities. Adenotonsillectomy is the primary treatment for pediatric OSAHS with adenotonsillar hypertrophy. Meanwhile, the interest in antiinflammatory agents, such as intranasal corticosteroids and leukotriene antagonists, for childhood OSAHS has also increased.

Abstract
Femtosecond laser drilled holes of GaSbBi were characterized by the joint measurements of photoconductivity (PC) spectroscopy and laser-beam-induced current (LBIC) mapping. The excitation light in PC was focused down to 60 μm presenting the spectral information of local electronic property of individual holes. A redshift of energy band edge of about 6-8 meV was observed by the PC measurement when the excitation light irradiated on the laser drilled holes. The spatial resolving of photoelectric property was achieved by the LBIC mapping which shows "pseudo-holes" with much larger dimensions than the geometric sizes of the holes. The reduced LBIC current with the pseudo-holes is associated with the redshift effect indicating that the electronic property of the rim areas of the holes is modified by the femtosecond laser drilling.

Abstract
Cyanobacteria in freshwater ecosystems can present a harmful effect on growth and development of plants through irrigation with contaminated water. In this study, the effects of microcystins (MCs)-containing cyanobacteria extract (CE) on DNA damage of apple, rape and rice were investigated to explore the phytotoxic mechanism of MCs through DNA fragmentation and RAPD analysis. Determination of DNA fragmentation by fluorescent dye DAPI showed that significant DNA damage was observed in rice seedlings after exposure to CE while DNA fragmentation in rape seedlings and apple cultures did not differ significantly between treatment and control groups. Qualitative characterization of genomic DNA fragmentation by agarose gel electrophoresis supported the quantitative determination using DAPI. The main changes in RAPD profiles of rape seedlings following exposure of lower doses of CE were variation in band intensity for the primers F03 and S01, while higher doses of CE caused loss of normal bands and appearance of new bands except band intensity changes. The data presented here demonstrate that DNA damage in plants occurs following exposure of microcystins, and the polymorphic RAPDs may be used as an investigation tool for environmental toxicology and as a useful biomarker for the detection of genotoxic effects of microcystins on plants.

Abstract
A droplet spotter for on-demand generation of pico- to femtoliter droplets was developed to meet the requirement for high-density spotting of chemicals on a surface. Our droplet spotter involves applying a approximately 1000-V and approximately 10-ms pulse voltage to the tip of a capillary tube (o.d. approximately 18 microns; i.d. approximately 11 microns) supplied with water or a dye solution. The capability of the spotter was demonstrated by preparing a microarray of dye molecules. The microarray was prepared by spotting approximately 30-fL droplets of a dye solution on a surface at the density of one spot per 20 x 20 micron 2.

Abstract
Effective energy windows for two-photon absorption (TPA) photopolymerization of resins were investigated and, with a properly selected laser pulse energy, exquisite three-dimensional (3D) microstructures with submicrometer spatial resolution were achieved. The results show the inherent utility of TPA in the fabrication of real 3D patterns. In particular, we propose and utilize a resin pre-exposure technique by which freely movable components affixed to an axle are built, demonstrating a new application of TPA in laser microfabrication.

Abstract
We have developed an effective approach to stretching DNA molecules with the flow of fluid generated by spin coating. Well-stretched A DNA molecules were observed using atomic force microscopy. Substrate properties sensitively affected the stretching behavior of DNA. Our experimental findings revealed that a mica surface treated with crystal violet, a cationic dye molecule, is suitable to the spin-coating procedure for stretching DNA. Moreover, compared with relaxed DNA, we observed reduced height of the stretched DNA, which was attributed mainly to elongation force applied to the DNA molecules from the fluid flow and strong adhesion force between DNA and the substrate. This simple and effective method for preparing stretched DNA could be useful in physically mapping genomic DNA in a high throughput.

Abstract
In order to study the mechanism of decreased blood pressure caused by an acute increase in biliary tract pressure, we observed house rabbit model of self-made caecus for changes in cardiovascular function when biliary tract pressure was increased. It was found that both the blood pressure and cardiac output evidently decreased (P < 0.05) parallelly, and the systolic pressure decreased more markedly than diastolic pressure. At the same time there was fluctuation in heart rate and in central venous pressure; but there was no significant difference between them (P > 0.05), suggesting that in the absence of infective agents, the increased biliary tract pressure can bring about a decrease in cardiac output, which is an important factor contributing to an early blood pressure decrease in acute cholangitis of severe type (ACST).

Abstract
In 1988, during an epidemic 431 cases of hepatitis A among a group 7,476 pregnant women were in the 12 Women Health Units at urban area of Shanghai, accounting for a morbidity rate of 5,765.1/100,000 pregnant women. The ratio of spontaneous abortion, induced abortion and term delivery were 18:15:67. There were 16 perinatal deaths in the 288 delivered cases. The perinatal mortality rate was 55.6/1,000 and its relative risk, as compared with that of the whole Shanghai Urban Districts was 4.1, at the same time, 83 cases of pregnancies associated with Hepatitis A (all confirmed by anti-hepatitis A Virus IgM assay) were studied in detail in the Shanghai Municipal Women Health Institute. The average birth weight of the new born was slightly lower and the mortality rate was significantly higher than those in a control group of 168 cases, there was no fetal infection as evidenced by fetal blood anti HAV IgM.
