Abstract
Head and neck squamous cell carcinoma is the sixth most common cancer worldwide and has high heterogeneity and unsatisfactory outcomes. To better characterize the tumor progression trajectory, we perform single-cell RNA sequencing of normal tissue, precancerous tissue, early-stage, advanced-stage cancer tissue, lymph node, and recurrent tumors tissue samples. We identify the transcriptional development trajectory of malignant epithelial cells and a tumorigenic epithelial subcluster regulated by TFDP1. Furthermore, we find that the infiltration of POSTN+ fibroblasts and SPP1+ macrophages gradually increases with tumor progression; their interaction or interaction with malignant cells also gradually increase to shape the desmoplastic microenvironment and reprogram malignant cells to promote tumor progression. Additionally, we demonstrate that during lymph node metastasis, exhausted CD8+ T cells with high CXCL13 expression strongly interact with tumor cells to acquire more aggressive phenotypes of extranodal expansion. Finally, we delineate the distinct features of malignant epithelial cells in primary and recurrent tumors, providing a theoretical foundation for the precise selection of targeted therapy for tumors at different stages. In summary, the current study offers a comprehensive landscape and deep insight into epithelial and microenvironmental reprogramming throughout initiation, progression, lymph node metastasis and recurrence of head and neck squamous cell carcinoma.

Abstract
Objective: To investigate the clinicopathological features, molecular genetic features, and differential diagnosis of intraductal carcinomas (IDC) of the salivary glands. Methods: Twenty-five cases of salivary gland IDC diagnosed at the Department of Oral Pathology, Shanghai Ninth People's Hospital and two cases from Department of Pathology, Henan Provincial People's Hospital, Zhengzhou, China from January 2008 to July 2023 were collected. Their clinical and pathological features were analyzed retrospectively. Fluorescence in situ hybridization and Sanger sequencing were performed. The patients were followed up and related literatures were reviewed. Results: There were 27 patients with IDC, including 15 males and 12 females, ranging in age from 20.0 to 80.0 years (mean 55.9 years). Clinically, the tumor often presented as a painless mass with a tumor diameter of 1.0-3.0 cm (mean 2.0 cm). All patients received surgical treatment. Twenty patients were followed up. One of them (1/20) died of lung cancer, while the rest survived without tumor recurrence. Histologically, IDC were classified as: intercalated (63.0%, 17/27), apocrine (25.9%, 7/27), oncocytic (7.4%, 2/27) and mixed (3.7%, 1/27) types. Intercalated tumors showed positive S-100 and negative androgen receptor (AR) immunoreactivity. Ki-67 proliferation index was low (about 1%-5%). Nine cases had the RET gene disruption, and 2 cases showed the BRAF V600E mutation. Apocrine tumors showed strong AR immunoreactivity but no S-100 immunoreactivity. Ki-67 proliferation index was high (about 10%-60%), and the RET gene rupture was detected in 1 case. Oncocytic tumors were similar to that of intercalated type in 2 cases, and RET gene disruption was detected in the both cases. Mixed tumors showed histologic features of oncocytic and apocrine patterns and harbored the RET gene disruption. Conclusions: IDC is a rare low-grade malignant tumor of the salivary gland and easily confused with other salivary gland tumors with similar morphology. Molecular testing is helpful for its differential diagnosis.

Abstract
Dichlorvos poisoning can cause muscarinic (M) -like symptoms, nicotinoid (N) -like symptoms and central nervous system manifestations. When severe poisoning is combined with refractory shock, the mortality rate exceeds 60%. At present, there are more and more studies on ECMO for poisoning, but there is no report on ECMO for treating refractory hypotension caused by dichlorvos poisoning. We analyzed 3 successful cases of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in the treatment of refractory shock caused by acute severe dichlorvos poisoning to explore the effectiveness of VA-ECMO in patients with severe poisoning.

Abstract
People with intellectual disabilities (PwID) have a bidirectional relationship with epilepsy. Nearly 25% of PwID have seizures and 30% people with epilepsy are thought to have a significant intellectual impairment. Furthermore, 70% of PwID are thought to have treatment-resistant epilepsy. In the United Kingdom, antiseizure medications (ASMs) are the second most widely prescribed psychotropic agent for PwID. However, it is unclear what the current evidence and patterns is on current prescribing of ASMs, including when and how a case is made to withdraw them. A narrative review along with an analysis of large-scale NHS Digital published data (2015-2020) on several aspects of ASM prescribing by general practices for PwID was undertaken. The review results and data analysis are consolidated and presented as 11 themes to provide a comprehensive overview of the study topic. Recent studies estimate that one-third and one-fifth of PwID are prescribed ASMs. A history of epilepsy is seen as the primary prescribing reason; however, often it is a legacy, and the indication is no longer clear. The proportion receiving ASMs continues to rise with age. This pattern of use does not correlate well with seizure onset. There are limited data on de-prescribing ASMs in PwID. The study population heterogenicity, associated polypharmacy, multimorbidity and higher sudden unexpected death in epilepsy risks are outlined. Suggestions are made from available evidence for improving prescribing practices for PwID and seizures, and key areas for further research in this complex clinical area are outlined.

Abstract
Objective: To compare the prognosis of mildly or severely symptomatic patients with obstructive hypertrophic cardiomyopathy (OHCM) who underwent alcohol septal ablation (ASA). Methods: This retrospective study cohort consisted of patients with OHCM who received ASA treatment in Beijing Anzhen Hospital, Capital Medical University from March 2001 to August 2021. These patients were divided into mildly and severely symptomatic groups according to the severity of clinical symptoms. Long-term follow-up was conducted, and the following data were collected: duration of follow-up, postoperatire treatment, New York Heart Association (NYHA) classification, arrhythmia events and pacemaker implantation, echocardiographic parameters, and cause of death. Overall survival and survival free from OHCM-related death were observed, and the improvement of clinical symptoms and resting left ventricular outflow tract gradient (LVOTG) and the incidence of new-onset atrial fibrillation were evaluated. The Kaplan-Meier method and log-rank test were used to determine and compare the cumulative survival rates of the different groups. Cox regression analysis models were used to determine predictors of clinical events. Results: A total of 189 OHCM patients were included in this study, including 68 in the mildly symptomatic group and 121 in the severely symptomatic group. The median follow-up of the study was 6.0 (2.7, 10.6) years. There was no statistical difference in overall survival between the mildly symptomatic group (5-year and 10-year overall survival were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year overall survival were 94.2% and 83.9%, respectively, P=0.405); there was also no statistical difference in survival free from OHCM-related death between the mildly symptomatic group (5-year and 10-year survival free from HCM-related death were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year survival free from HCM-related death were 95.2% and 92.6%, respectively, P=0.846). In the mildly symptomatic group, NYHA classification was improved after ASA (P<0.001), among which 37 patients (54.4%) were in NYHA class Ⅰ, and the resting left ventricular outflow tract gradient (LVOTG) decreased from 67.6 (42.7, 90.1) mmHg (1 mmHg=0.133 kPa) to 24.4 (11.7, 35.6) mmHg (P<0.001). In severely symptomatic group, NYHA classification was also improved post ASA (P<0.001), among which 96 patients (79.3%) improved by at least one NYHA classification, and the resting LVOTG decreased from 69.6 (38.4, 96.1) mmHg to 19.0 (10.6, 39.8) mmHg (P<0.001). The incidence of new-onset atrial fibrillation was similar between the mildly and severely symptomatic groups (10.2% vs. 13.3%, P=0.565). Cox multivariate regression analysis showed that age was an independent predictor of all-cause mortality in OHCM patients post ASA (HR=1.068, 95%CI 1.002-1.139, P=0.042). Conclusions: Among patients with OHCM treated with ASA, overall survival and survival free from HCM-related death were similar between mildly symptomatic group and severely symptomatic group. ASA therapy can effectively relieve resting LVOTG and improve clinical symptoms in mildly or severely symptomatic patients with OHCM. Age was an independent predictor of all-cause mortality in OHCM patients post ASA.

Abstract
BACKGROUND People with epilepsy (PWE) and people with intellectual disabilities (ID) both live shorter lives than the general population and both conditions increase the risk of death further. We aimed to measure associations between certain risk factors for death in PWE and ID. METHODS A retrospective case-control study was conducted in ten regions in England and Wales. Data were collected on PWE registered with secondary care ID and neurology services between 2017 and 2021. Prevalence rates of neurodevelopmental, psychiatric and medical diagnoses, seizure frequency, psychotropic and antiseizure medications (ASM) prescribed, and health activity (epilepsy reviews/risk assessments/care plans/compliance etc.) recorded were compared between the two groups. RESULTS 190 PWE and ID who died were compared with 910 living controls. People who died were less likely to have had an epilepsy risk assessment but had a greater prevalence of genetic conditions, older age, poor physical health, generalized tonic-clonic seizures, polypharmacy (not ASMs) and antipsychotic use. The multivariable logistic regression for risk of epilepsy-related death identified that age over 50, medical condition prevalence, antipsychotic medication use and the lack of an epilepsy review in the last 12 months as associated with increased risk of death. Reviews by psychiatrists in ID services was associated with a 72% reduction in the odds of death compared neurology services. CONCLUSIONS Polypharmacy and use of antipsychotics may be associated with death but not ASMs. Greater and closer monitoring by creating capable health communities may reduce the risk of death. ID services maybe more likely to provide this holistic approach.

Abstract
Antiseizure medications (ASMs) are the second most widely prescribed psychotropic for people with intellectual disabilities in England. Multiple psychotropic prescribing is prevalent in almost half of people with intellectual disabilities on ASMs. This analysis identifies limited evidence of ASM benefit in challenging behaviour management and suggests improvements needed to inform clinical practice.

Abstract
Objective: To establish an in vitro organoid model of human salivary gland basal cell adenoma (BCA). Methods: Fresh tumor sample from a 66-year-old female patient diagnosed with salivary gland BCA was collected from the Dpartment of Oral pathology, Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine in October 2021. And the organoid culture was performed in vitro in a culture medium based on solid droplets of matrix gel, and the growth of the organoid was observed by inverted microscopy. After 14 days, the organoid was fixed in 10% neutral formalin and made into paraffin blocks by agar pre-embedding paraffin embedding method, sectioned. HE staining, morphological observation and immunohistochemical staining of p63, Ki-67, cytokeratin14 (CK14), β-catenin, S-100 and calponin were used for organoids identification. Results: The established BCA organoids were lobulated nodular locally under light microscopy, with deposition of eosinophilic glass-like material around the nests of organoid cells, similar to the morphological architectures of the parental BCA. Immunohistochemistry showed that organoids expressed CK14, p63, and β-catenin in various degree, which was consistent with the immunophenotypic characteristics of the parental BCA tumor cells. Conclusions: An in vitro culture system of BCA organoids was preliminarily established which provides a new model for the study of the pathogenesis of salivary gland tumors.

Abstract
Objective: To discuss the clinical value of preserving subvalvular structure in mitral and aortic valve replacement surgery and its effect on left ventricular contractility. Methods: A total of 97 patients who underwent mitral valve replacement surgery in the Adult Cardiac Surgery of Heart Center of Henan Provincial People's Hospital, Central China Fuwai Hospital from June 2016 to December 2018 were selected as the research subjects, of whom 45 cases were preserved subvalvular structure and 52 cases were in the total resection group (intraoperative total resection of the mitral valve and subvalvular chordae tendineae). General cardiac function indexes and left ventricular function quantitative indexes were compared before and in 3 months and 6 months after the operation of the two groups; The changes of the overall longitudinal strain of the long axis of the apex and the overall circumferential strain of the short axis of the left ventricle determined by the two-dimensional speckle tracking technology were compared before and after the operation. Results: The ages of the patients in the preservation group and the total resection group were (41.8±11.3) and (43.3±10.6) years old, respectively, and the male proportions were 58.0% (26 cases) and 44.0% (23 cases), respectively, with no significant difference (all P>0.05). The aortic occlusion time and cardiopulmonary bypass time of the patients in the preservation group were (57.8±4.5) and (78.6±6.7) min, respectively, which were longer than those in the total resection group [(48.1±4.4) and (48.1±4.4) min, respectively] (all P<0.05). The left atrial pressure of the patients in the preservation group at shutdown was (8.4±1.8) mmHg (1 mmHg=0.133 kPa), which was lower than that of the total resection group (11.3±2.5) mmHg (P<0.001). There were interaction effects between groups and time in regards to the left ventricular end-diastolic diameter ( LVEDD ), left ventricular ejection fraction ( LVEF ) and Tei index, as well as the strain rate of mitral annulus and left ventricular wall of interventricular septum of the preservation group and the total resection group (all P<0.05). LVEDD and LVEF of patients in the preservation group at 3rd month after operation were (44.7±4.0) mm and (45.5±4.2) mm, and at 6th months were (56.5±4.9)% and (58.8±5.0)%, respectively, all larger than (42.7±3.6) mm and (42.7±3.6) mm, (54.5±4.6)% and (56.3±4.8)% of the total resection group. The measured value of LVESD in the preservation group at 3rd month after surgery was (32.6±3.2) mm, which was greater than that in the total resection group (31.2±3.4) mm (P<0.05). The Tei index of patients in the preservation group at 3rd and 6th months after surgery were 1.0±0.2 and 0.8±0.2, respectively, which were lower than those in the total resection group 1.2±0.3 and 0.9±0.2 (all P<0.05). Conclusion: Preserving the subvalvular structure during mitral valve replacement surgery can better improve the patient's left ventricular function and left ventricular systolic capacity.

Abstract
Objective: To observe the therapeutic effects of alcohol septal ablation (ASA) in mildly symptomatic patients (NYHA class Ⅱ) with hypertrophic obstructive cardiomyopathy(HOCM). Methods: This retrospective study included 150 mildly symptomatic patients with HOCM hospitalized in Beijing Anzhen Hospital affiliated to Capital Medical University from March 2001 to December 2017, consisting of medical therapy group (n=102) and ASA group (n=48). Baseline clinical data were collected, patients were followed up to a mean of 6.0 (3.5, 8.1) years. Overall and HCM-related mortality events (including chronic heart failure, atrial fibrillation related stroke, sudden cardiac death) were observed in the two groups. Moreover, the improvement of NYHA function classification and left ventricular outflow tract gradient (LVOTG) were also evaluated. Survival analysis was performed by Kaplan-Meier method. Results: Age of this cohort was (52.9±14.5)years, 92 cases(61.3%) were male. In the follow-up, LVOTG was reduced from (85.8±35.4)mmHg (1 mmHg=0.133 kPa) to (27.7±19.8)mmHg (P<0.001) in the ASA group, and from (66.3±35.0)mmHg to (56.5±27.7)mmHg in medical therapy group(P<0.01). At the last clinical follow-up, there were 32 patients (66.7%) whose LVOTG were<30 mmHg, septal thickness decreased from (20.3±3.8)mm to (16.1±3.4)mm (P<0.001), NYHA classification was also remarkably improved (P<0.001). New-onset atrial fibrillation tended to be lower in the ASA group compared to medical therapy group (9.3%(4/43) vs. 20.8%(20/96),P=0.096). Eleven patients (10.8%) in the medical therapy group and 2 patients (4.2%) in the ASA group died during the follow-up. One patient received pacemaker during the peri-procedural period, 1 patient was implanted with two-chamber pacemaker due to Ⅲ° atrioventricular block at 10 years after operation in the ASA group. Survival free of all-cause mortality of ASA group at 5 and 10 years was 97.9% and 97.9%, respectively, which was comparable to the medical therapy group (P=0.231). Survival free of HCM-related mortality was similar between the two groups (P=0.397). Conclusions: Compared with medical therapy in mildly symptomatic patients with HOCM, long-term survival rate is similar after ASA. Meanwhile, ASA can remarkably reduce LVOTG and improve the clinical status of the patients. Therefore, ASA may be used as an alternative therapy for mildly symptomatic HOCM patients.

Abstract
Objectives People living with HIV (PLWH) have a high risk of kidney injury. Measurement of serum creatinine, along with proteinuria, is not sensitive to detect early kidney injury. Here, we investigated novel urinary biomarkers of early renal injury in PLWH. Methods We performed a cross‐sectional study of 166 antiretroviral‐naïve PLWH and 99 HIV‐negative persons who all had an estimated glomerular filtration rate > 90 mL/min/1.73 m2. We compared the levels of seven urinary biomarkers between the two groups using the propensity score matching (PSM) approach and explored the risk factors associated with elevated urinary biomarkers in PLWH. Results Eighty‐three pairs were successfully matched based on PSM. Compared with the HIV‐negative group, the HIV‐positive group had higher ratios of N‐acetyl‐β‐D‐glucosaminidase (NAG) to urine creatinine (UCr), alpha1‐microglobulin (α1‐M) to UCr, kidney injury marker‐1 (KIM‐1) to UCr, neutrophil gelatinase‐associated lipocalin to UCr, and epidermal growth factor to UCr, whereas the Tamm–Horsfall protein to UCr ratio and the abnormal albumin to UCr ratio were not significantly different. Positive correlations were observed between HIV RNA level and NAG: UCr (rs = 0.32; P < 0.001) and α1‐M:UCr (rs = 0.24; P = 0.002) ratios, and negative correlations were observed between CD4 cell count and NAG:UCr (rs = –0.34; P < 0.001), KIM‐1:UCr (rs = –0.16; P = 0.042) and α1‐M:UCr (rs = –0.36; P < 0.001) ratios. In multivariate linear regression analyses, older age, lower total cholesterol and higher HIV RNA were independently associated with higher NAG:UCr; older age, lower total cholesterol and lower CD4 cell count were independently associated with higher α1‐M:UCr. Conclusions In comparioson with HIV‐negative participants, PLWH were more likely to have tubular injury. Early antiretroviral treatment might mitigate the development of kidney injury.

Abstract
Objective: To investigate the risk factors and prognostic impact of massive introperative blood loss in posterior spinal fusion (PSF) surgery for adolescent idiopathic scoliosis (AIS). Methods: Clinical data were collected of 1 896 AIS patients who underwent PSF surgery under general anesthesia in Drum Tower Hospital Affiliated to Nanjing University Medical School from November 2010 to October 2019 and retrospectively analyzed. According to the volume of intraoperative blood loss, the patients were divided into the massive introperative blood loss group [estimated blood loss (EBL)/estimated blood volume (EBV)≥30%] and the non-massive introperative blood loss group (EBL/EBV<30%). The perioperative parameters between the two groups were compared, single factor analysis and multivariate logistic regression analysis was performed to identify independent risk factors related to massive introperative blood loss in PSF surgery. Results: A total of 1 896 AIS patients who underwent PSF surgery were included in the study. There were 298 males and 1 598 females, with an age of (14.5±1.7) years. Among them, 633 (33%) experienced massive intraoperative blood loss. The factors significantly related to the massive blood loss during PSF surgery in this study are: sex, body mass index(BMI), preoperative blood platelet count (PLT), prothrombin time, international normalized ratio(INR), preoperative Cobb angle, duration of operation, the number of fused levels, the number of screws, thoracoplasty, intraoperative use of tranexamic acid and dexmedetomidine; The independent factors included duration of operation longer than 4 hours(OR=4.311,P<0.001), the number of fused levels to be more than 10(OR=4.044,P<0.001), thoracoplasty (OR=2.174,P=0.019), BMI lower than 18.1 kg/m2(OR=2.094,P<0.001), preoperative PLT less than 186.5×109/L(OR=1.480,P=0.009), preoperative INR larger than 1 (OR=1.531,P=0.003) and preoperative Cobb angle larger than 53°(OR=1.306,P=0.036) ;Intraoperative use of tranexamic acid (OR=0.770, P=0.047) and dexmedetomidine (OR=0.653, P=0.008) are protective factors for massive intraoperative blood loss. In addition, in the massive intraoperative blood loss group, length of postoperative hospital stay (P<0.001), volume of postoperative incision drainage (P<0.001), postoperative allogeneic blood transfusion rate (22.7% vs 14.3%, P<0.001), incidence of postoperative hypoalbuminemia (90.3% vs 80.7%, P<0.001) and the number of rescue opioid analgesic requirements after surgery (P=0.006) were significantly higher than those in the non-massive introperative blood loss group. Conclusions: Longer operation duration, higher number of fusion levels, lower BMI, lower preoperative PLT, higher INR, larger preoperative Cobb angle and intraoperative thoraplasty are independent risk factors for massive intraoperative blood loss in AIS patients undergoing PSF surgery. Intraoperative use of tranexamic acid and dexmedetomidine can reduce the risk of massive blood loss in PSF surgery. Massive intraoperative blood loss significantly affects the patient's prognosis.

Abstract
OBJECTIVES Tuberculosis (TB) is the most common and fatal opportunistic co-infection among HIV-infected individuals. While TB-associated mortality predominantly occurs in the first 90 days after admission, such a correlation remains unclear in HIV/TB co-infected patients. Thus, we aimed to investigate the 90-day mortality and associated risk factors among HIV/TB co-infected patients in China. METHODS Adult patients with HIV and a newly confirmed TB diagnosis admitted to the Shanghai Public Health Clinical Center between September 2009 and August 2017 were enrolled. Clinical and laboratory characteristics, key treatments and outcomes were collected retrospectively. The associations between different factors and early mortality were analysed. RESULTS Of the 485 laboratory-confirmed HIV/TB patients [median (range) age = 39 (19-79) years], 413 (85.15%) were male. Diagnosis was confirmed by culture, pathology and acid-fast bacilli smear alone in 362 (74.6%), 6 (1.2%) and 117 (24.1%) patients, respectively. Multiple drug-/rifampin-resistant TB was detected in 21 (5.8%) of the 367 patients with a positive culture. Rifampin or rifabutin was administered to 402 (82.9%) patients. Additionally, 66 (13.6%) and 86 (17.7%) died within 90 days and 1 year of admission, respectively. Of the 64 TB-related deaths, 59 (92.2%) occurred within 90 days of admission. In Cox regression, central nervous system (CNS) TB [odds ratio (OR) = 2.49, 95% confidence interval (CI): 1.46-4.23, P < 0.001], no antiretroviral therapy (ART) within 3 months after admission (OR = 11, 95% CI: 6.4-18.9, P < 0.001), and plasma albumin level < 25 g/L (OR = 1.91, 95% CI: 1.07-3.40, P = 0.021) were associated with early death. CONCLUSIONS Tuberculosis co-infection was prevalent and fatal in HIV-infected patients, with most deaths occurring within 90 days of admission. Early mortality was associated with CNS-TB, no ART, and serum albumin level < 25 g/L.

Abstract
PURPOSE This study identifies epilepsy-related characteristics and SUDEP risk factors in people with epilepsy (PWE) attending an urban community ID service in the UK where managing epilepsy is not part of the service remit, to understand the care provided to this vulnerable population. METHODS An electronic database search in a north London community ID service (catchment population approx. 290,000) identified relevant ID/epilepsy characteristics in PWE to compare those with mild ID to moderate-profound ID. The SUDEP and Seizure Safety Checklist ("Checklist"), was administered to patients and families/carers. Risk management data was compared to similar data from Cornwall UK where PWE are supported within the ID service and the Checklist is used annually. RESULTS One fifth (137/697) of people attending the service had epilepsy. Over 3/4 had moderate-profound ID. Neurodevelopmental disorders were coexistent in 2/3, psychiatric conditions in 1/3 (1/4 of which was psychosis). The mean number of anti-seizure drugs was 1.45 ± 0.98, and 1/4 were taking psychotropic medications. Over a third did not have an epilepsy care plan. None contacted (n = 103) had SUDEP awareness. The median number of Checklist risk factors was seven (IQR 4.5-9). A third had experienced seizures lasting >5 min or status epilepticus. In comparison to the Cornish ID data significant differences were evident in four of seven modifiable risk factors. CONCLUSIONS This real world study highlights the complexity and risks among PWE and ID. The lack of a "joined up" approach can undermine the safety of this vulnerable population. Person-centred risk communication and care plans are easily achievable and essential.

Abstract
Summary In recent years, the cartilage tissue engineering technology has rapid development, and shows a bright prospect in the field of cartilage defect and repair. In this paper, the field of rhinology cartilage tissue engineering research progress were reviewed, with the purpose to understand the status quo, and determine the next step research direction. From the research in recent years, we found that although cartilage tissue engineering technique could play an important role in the field of rhinology, but the progress to date was still lagging behind. In the published literature, there were few basic and applied research about cartilage tissue engineering techniques for nasal diseases. There have a small amount of applied research report, mainly concentrated in the animal experiments. There are still quite a distance from a wide range of clinical application. Based on the existing research results, cartilage tissue engineering technique in nasal plastic and reconstruction surgery has great potential in clinic application and needs more further research.

Abstract
OBJECTIVE To investigate the values of diffusion tensor imaging (DTI) and virtual reality (VR) techniques in design surgery program of gliomas near eloquent regions. METHODS In this study, 35 cases were retrospectively analyzed with gliomas involved language areas or rolandic regions operated in Department of Neurosurgery, Peking University Third Hospital from January 2015 to January 2019. Surgery programs were performed by Dextroscope virtual reality system. The pre-operative data, such as the magnetic resonance imaging (MRI), magnetic resonance arteriography (MRA) and DTI was transferred into the VR computer for restitution,Tumors, neural fiber tracts and blood vessels were reconstructed to simulate operation and design individual surgical plan. Neurological function was evaluated 1 week, 1 month and 3 months after operation. RESULTS Virtual reality three-dimensional images of the 35 cases were successfully achieved, including neural fiber tracts,blood vessels and the lesions. The displacement and destruction of fiber tracts, the anatomic relationship between tumor and important fiber bundle, artery and vein could be shown clearly. Surgical simulation and surgery program of VR of the 35 patients were successfully performed. The 3D images obtained from virtual reality near to the real surgery. Ten of the 35 cases were defined as rolandic regions tumors, 14 of the 35 cases were defined as language areas tumors and 11 of the 35 cases involved both language areas and rolandic regions. Complete resection of enhancing tumor (CRET) was achieved in 30 cases (85.7%), subtotal resection in 5 cases (14.3%), neurological function improved in 34 cases (97.1%) after operation,and 1 case had no improvement compared with that before(2.9%). Thirteen cases without neurological deficit pre-operation, showed transient neurological deficit ,which were recovered about 10 days post-operation, 12 of 22 cases with pre-operative neurologic deficit, improved one week postoperation, 9 of 22 cases with pre-operative neurologic deficit improved one month after operation, the rest 1 case was recurrent with glioblastoma with aggravated hemiplegia symptom after operation, who died of cerebral hernia 2 months later. CONCLUSION Dextroscope virtual reality system can clearly expose and quantify the 3D anatomic relationship of tumors, neural fiber tracts and blood vessels surrounding gliomas near eloquent regions, which is helpful to design the best individualized surgery program, to improve surgical effect.

Abstract
Summary Deformity of the auricle can result from congenital defects, oncologic resection, or traumatic injury. Current clinical strategy is to utilize autologous costal cartilage for reconstructing auricular scaffolds with long-term stability. However, this method is limited by donor-site morbidity, a complex surgical sculpting process, and differing mechanical properties compared to elastic auricular cartilage. Alternatively, alloplastic implants can offer precise shape and avoid donor-site surgery, but suffer from poor biocompatibility and high rates of infection and extrusion. A tissue engineering approach to auricular reconstructions would overcome the limitations of both autologous and alloplastic transplants. In this review we focus on tissue engineering auricular cartilage reconstruction, including auricular seed cells culture and their differentiated control strategy, scaffolds choices and design technique. Many studies found that auricular chondrocytes were the most suitable seed cells to fabricate elastic cartilage; progenitor cells from auricular cartilage could differentiate into elastic chondrocytes, and other types of chondrocytes had its limitation because of the final ossification. Many types of growth factors had the differing potential ability for accelerating chondrocytes growth, differentiation, or maintaining chondrocytes phenotype. Recent advances in tissue engineering auricular cartilage, including several clinic applications, implied that tissue engineering auricules would become a hopefully potential soulution for the future of auricular reconstruction.

Abstract
Objective: To explore and analyze the effects of airway management team (AMT) in the treatment of severely mass burn patients combined with inhalation injury. Methods: The clinical data of 58 severely burned patients combined with inhalation injury hospitalized in our unit from January 2012 to August 2014, conforming to the inclusion criteria, were retrospectively analyzed. According to whether airway management was implemented by AMT or not, patients hospitalized from January 2012 to July 2014 were divided into control group (n=27), while patients in Kunshan factory aluminum dust explosion accident hospitalized on 2nd August 2014 were divided into observation group (n=31). Patients in control group received regular airway nursing carried out by nurses on duty, while patients in observation group received specialized airway concentration nursing implemented by AMT. The concrete implementation included overall assessment of patients' airway, elaborate airway care, and controlled management of mechanical ventilation. Arterial blood gas indexes and oxygenation index of patients in the two groups on post injury day (PID) 1, 7, and 14 were compared. Sputum viscosity, ventilator-associated pneumonia (VAP) occurrence rate, and ventilation time of patients in the two groups in post injury week(s) 1, 2, and 3 after admission were monitored and recorded. Survival rates of patients in the two groups were compared. Data were processed with analysis of variance for repeated measurement, t test and Bonferroni correction, chi-square test, and Wilcoxon rank sum test. Results: (1) There were no statistically significant differences in pH value, arterial partial pressure of oxygen (PaO(2)), arterial partial pressure of carbon dioxide (PaCO(2)), arterial oxygen saturation (SaO(2)), and oxygenation index of patients in the two groups on PID 1 (t=0.595, -0.166, 1.518, -0.828, 0.458, P>0.05). The pH values of patients in observation group on PID 7 and 14 were 7.327±0.050 and 7.367±0.043, respectively, significantly better than those in control group (7.304±0.021 and 7.390±0.029, respectively, t=-2.385, 2.391, P<0.05). The PaO(2) values of patients in observation group on PID 7 and 14 were (95.1±6.7) and (106.3±7.8) mmHg (1 mmHg=0.133 kPa), respectively, significantly higher than those in control group [(91.6±5.7) and (102.0±8.3) mmHg, respectively, t=-2.109, -2.059, P<0.05]. The PaCO(2) values of patients in observation group on PID 7 and 14 were (41±4) and (40±4) mmHg, respectively, significantly lower than those in control group [(43±5) and (43±4) mmHg, respectively, t=2.220, 2.304, P<0.05]. The SaO(2) values of patients in observation group on PID 7 and 14 were 0.95±0.04 and 0.96±0.04, respectively, significantly higher than those in control group (0.93±0.05 and 0.94±0.05, respectively, t=-2.201, -2.016, P<0.05). The oxygenation indexes of patients in observation group on PID 7 and 14 were (286±18) and (329±20) mmHg, significantly higher than those in control group [(277±14) and (306±58) mmHg, respectively, t=-2.263, -2.022, P<0.05]. (2) Sputum viscosity of patients in observation group in post injury week(s) 1, 2, and 3 were superior to that in control group (Z=-2.096, -2.076, -2.033, P<0.05). (3) VAP occurrence rate of patients in observation group was lower than that in control group, and time of mechanical ventilation of patients in observation group was shorter than that in control group (χ(2)=4.244, t=2.425, P<0.05). (4) Survival rate of patients in observation group was higher than that in control group (χ(2)=4.244, P<0.05). Conclusions: The special intensive care of airway management by AMT can effectively improve the oxygenation status of severely burned patients combined with inhalation injury, alleviate the sputum viscosity, reduce the occurrence of VAP, and shorten the time of mechanical ventilation, thus benefits the treatment of severely mass burn patients combined with inhalation injury.

Abstract
Objective:The aim of this study was to study the assessed value of Epworth sleep scale (ESS) and arousal index in severe obstructive sleep apnea hypopnea syndrome (OSAHS) patients.Method:The 1193 severe OSAHS adults diagnosised by polysomnography recordings were divided into 3 groups according to ESS: the mild group (ESS≤12), the moderate group (13≤ESS≤17) and the severe group (ESS≥18). The apnea hypopnea index(AHI), apnea index (AI), hypopnea index(HI), the lowest oxygen saturation (LSaO₂), arousal index (ArI), and body mass index (BMI) were compared between each groups.Result:Significant differences were observed in ArI, AHI, AI, HI, LSaO₂ between each groups (P< 0.05). ESS and ArI were positively correlated with AHI and AI (r=0.187-0.399, P< 0.05). ESS and ArI showed a weak negative correlation with LSaO2 and HI (r=-0.14--0.448, P< 0.05).Conclusion:ArI and ESS are important indexes to evaluate the severity of severe OSAHS patients.

Abstract
INTRODUCTION Cardiovascular events are common in people with aortic aneurysms. Arterial calcification is a recognised predictor of cardiovascular outcomes in coronary artery disease. Whether calcification within abdominal and thoracic aneurysm walls is correlated with poor cardiovascular outcomes is not known. PATIENTS AND METHODS Calcium scores were derived from computed tomography (CT) scans of consecutive patients with either infrarenal (AAA) or descending thoracic aneurysms (TAA) using the modified Agatston score. The primary outcome was subsequent all cause mortality during follow-up. Secondary outcomes were cardiovascular mortality and morbidity. RESULTS A total of 319 patients (123 TAA and 196 AAA; median age 77 [71-84] years, 72% male) were included with a median follow-up of 30 months. The primary outcome occurred in 120 (37.6%) patients. In the abdominal aortic aneurysm group, the calcium score was significantly related to both all cause mortality and cardiac mortality (odds ratios (OR) of 2.246 (95% CI 1.591-9.476; p < 0.001) and 1.321 (1.076-2.762; p = 0.003)) respectively. In the thoracic aneurysm group, calcium score was significantly related to all cause mortality (OR 6.444; 95% CI 2.574-6.137; p < 0.001), cardiac mortality (OR 3.456; 95% CI 1.765-4.654; p = 0.042) and cardiac morbidity (OR 2.128; 95% CI 1.973-4.342; p = 0.002). CONCLUSIONS Aortic aneurysm calcification, in either the thoracic or the abdominal territory, is significantly associated with both higher overall and cardiovascular mortality. Calcium scoring, rapidly derived from routine CT scans, may help identify high risk patients for treatment to reduce risk.

Abstract
Mechanochemical ablation (MOCA) is a nonthermal nontumescent technique used in the treatment of superficial venous disease. This review analyzed the available data on the efficacy and safety of MOCA. A systematic literature search was performed. Of 101 studies identified, 14 were suitable for inclusion. The studies were found to be heterogeneous in design, and the quality of evidence was found to be low or very low. MOCA was demonstrated to be effective in the short-term with minimal complications. Consensus guidelines and definitions of reporting outcome measures must be standardized to allow comparison with other techniques.

Abstract
Objective: Tailor-made notched music was applied to alleviate the symptoms of chronic idiopathic tinnitus and compared its effectiveness with other existing sound treatment of tinnitus. Methods: Subjects (n=43; ears=75 )were recruited during June 2015 to October 2016 from the out-patients of our hospital. These patients had chronic (longer than 6months) and idiopathic tinnitus, with or without significant sensorineural hearing loss. In the prospective design, the patients were randomly divided into group A (treated with tailor-made notched music) and group B (treated with analogous sound masking), and received the treatment for 3 months. The tinnitus scale, tinnitus questionnaire and audiological findings were evaluated before treatment, and at one month and three months after treatment started. Results: After onemonth of treatment, the effective rate between the two groups was 40.9% and 42.9%, there was no significant difference between the two groups (χ(2)= 0.017, P=0.897). The average VAS for patients in group A showed more decrease in group A than in group B(VAS: 1.8 vs. 0.8, the percentage : 29.5% vs. 13.6%), but there was no significant difference between the two groups (t=-1.450, P=0.155). After 3 months of treatment, the effective rates were 68.2% and 23.8%, respectively. There was significant difference between the two groups (χ(2)= 8.503, P=0.004). The difference of the VAS scores between the two groups was statistically significant (t=-3.263, P=0.002), and the VAS score of group A was less.After 3 months of treatment, there was significant decreaseinthe average tinnitus loudness for patients in group A(t=5.569, P<0.01), and there was no significant changein group B(t=-0.953, P=0.374). There was also significant decreasein the scores of tinnitus handicap inventory (THI) (F=7.334, P<0.05), loudness visual analog scale (VAS) (F=20.48, P<0.001), and the proportion of patients with moderate to severe tinnitus(χ(2)=11.289, P<0.05) in the group A, and there was no significant change in group B(F=2.198, F=0.989, χ(2)=1.651; P=0.120, P=0.378, P=0.438>0.05). Conclusions: Our resultssuggest that long-term normalized listening to tailor-made notched music, can significantly reduce the perceived tinnitus loudness in varying degrees and improve the quality of life of patients. The effects and possible mechanism of this method were discussedin this paper.

Abstract
This study investigated the effects of Moringa oleifera (MO) as a partial substitute of alfalfa hay on milk yield, nutrient apparent digestibility and serum biochemical indexes of dairy cows. MO was harvested at 120 days post-seeding. Fresh MO was cut, mixed with chopped oat hay (425:575 on a DM basis), ensiled and stored for 60 days. Sixty healthy Holstein dairy cows were allocated to one of three groups: NM (no MO or control), LM (low MO; 25% alfalfa hay and 50% maize silage were replaced by MO silage) or HM (high MO; 50% alfalfa hay and 100% maize silage were replaced by MO silage). The feeding trial lasted 35 days. The LM and HM diets did not affect dry matter (DM) intake, milk yield or milk composition (lactose, milk fat, milk protein and somatic cell count). The apparent digestibility of DM and NDF was lower for HM group than NM group. Additionally, there were no significant differences in serum biochemical indexes between the LM and NM groups. The HM group had lower serum concentrations of total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol and higher serum concentrations of urea than the NM group. The partial replacement of alfalfa hay (≤50%) and maize silage with MO silage had no negative effects on milk yield, in vivo nutrient apparent digestibility or serum biochemical indexes of lactating cows.

Abstract
Levels of hydrogen sulfide (H2S), a gaseous signaling molecule, are reduced in the serum of individuals who smoke. We hypothesized that tobacco smoke influenced smooth muscle relaxation by decreasing H2S levels and this effect could also influence expression of cystathionine γ-lyase (CSE) and sulfonylurea receptor-2 (SUR-2). The aim of this study was to explore the effect of tobacco smoke on H2S-mediated rat thoracic aorta relaxation and its possible mechanism. Thirty-two Sprague-Dawley rats were divided into four groups: control (C) group, short-term smoker (SS) group, mid-term smoker (MS) group, and long-term smoker (LS) group. H2S concentrations in serum, action of H2S on rat aortic vascular relaxation, and expression of CSE and SUR-2 in thoracic aortic smooth muscle were measured. Although there was no significant difference in H2S between the C and the SS groups, concentration of H2S was significantly reduced in both the LS and MS groups compared to control (P<0.01). Furthermore, H2S was significantly lower in the LS than in the MS group (P<0.05). Rat aortic vascular relaxation was lower in all three treatment groups compared to the control, with the most significant decrease observed in the LS group (P<0.05 compared to the MS group). Expression of CSE and SUR-2 was reduced in the LS and MS groups compared to control (P<0.05), with the lowest levels observed in the LS group (P<0.05). Therefore, tobacco smoke reduced expression of CSE and SUR-2 in rat thoracic aorta, which may inhibit H2S production and vascular dilation.

Abstract
Objective: To construct tissue engineered-epithelial patches with human adipose-derived mesenchymal stem cells (hADSC) and extracellular matrix scaffold (ECM), and to observe their morphological characteristics and biological behaviors. Methods: The cultured and purified hADSC were co-cultured with the ECM. The adhesion of hADSC formed sheet on the ECM were observed by the scanning electron microscopy. The activity and apoptosis of hADSC cultured on the ECM were observed by laser scanning confocal microscope. The autocrine function of hADSC were determined by qPCR(hepatoeyte growth factor, transforming growth factor-β, epidermal growth factor). Results: hADSC proliferated actively when cultured on the ECM. The scanning electron microscopy demonstrated that the bottom of the ECM possessed smooth, with uneven thickness, widely interconnected collagen bundles. Meanwhile, it showed that hADSC had good adhesion with ECM surface and grew overlapped. The immunofluorescence revealed that hADSC proliferated stably, did not appear a large number of apoptosis when cultured on the ECM. qPCR results indicated that the autocrine function of hADSC cultured on the ECM were significantly higher than those in non-scaffold group(P<0.05). Conclusion: hADSC has good biocompatibility with ECM scaffold. hADSC grows well in the environment of ECM and has active secretion function.

Abstract
The therapeutic effect of vacuum-assisted closure (VAC) has been confirmed in many types of complex wounds, but there are few relevant reports regarding seawater-immersed wounds. The aim of this study was to determine the effect of VAC on seawater-immersed wound healing under different negative pressures and explore the optimal negative pressure value. Four purebred miniature pigs were used as the experimental animal models. Four acute, symmetrical wounds were made on each side of the spine and designated as the experimental group (wounds with 2 h of seawater immersion) and the control group (wounds without seawater immersion). Wounds were divided into a conventional dressing group and 3 further groups with different VAC therapies (negative pressure at either 120, 180, or 240 mmHg). The extent of wound healing, and speed of granulation growth and re-epithelialization were measured. Bacterial flora distribution in the wounds was observed, and fibronectin levels in the exudate of the wounds were tested. Results showed that seawater immersion aggravated wound injury and that VAC therapy with 180 mmHg negative pressure induced the fastest epidermis migration, obvious edema elimination, significant capillary proliferation, and the highest level of fibronectin, and that in wounds, the proportion of Gram-negative bacteria tended to decrease and that of Gram-positive bacteria tended to increase. Our results show that VAC promotes seawater-immersed wound healing and that 180 mmHg negative pressure may be optimal for wound healing.

Abstract
This study aimed to explore new opportunities for developing targeted therapy for triple-negative breast cancer (TNBC) by analyzing the significance and association between p53 and epidermal growth factor receptor (EGFR) expression in different molecular subtypes of breast cancer. The clinical and pathological data of 264 patients with breast cancer receiving surgery in our hospital from January 2012 to August 2013 were retrospectively analyzed. According to the expression of estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 (HER2), Ki-67, CK5/6, p53, and EGFR detected by immunohistochemical methods, breast cancer was divided into four molecular subtypes. Then, the expression of p53 and EGFR as well as their correlation in the different subtypes were determined. Among the four subtypes, luminal B breast cancer was the most common type. TNBC and HER2-enriched breast cancer had larger tumor sizes with higher expression of Ki-67 as compared with the luminal types. TNBC had a lower lymph node metastasis rate but higher CK5/6 and EGFR expression than the other three types. The expression of p53 was higher in luminal B, HER2-enriched, and triple-negative breast cancers, and this was positively correlated with the expression of EGFR in TNBC but not in the other subtypes. p53 and EGFR expression was positively correlated in TNBC, which enables us to explore the molecular biological characteristics of TNBC, so as to provide new ideas for the treatment of TNBC.

Abstract
Early renal graft injury could result in remote pulmonary injury due to kidney-lung cross talk. Here we studied the possible role of regulated necrosis in remote lung injury in a rat allogeneic transplantation model. In vitro, human lung epithelial cell A549 was challenged with TNF-α and conditioned medium from human kidney proximal tubular cells (HK-2) after hypothermia-hypoxia insults. In vivo, the Brown-Norway rat renal grafts were extracted and stored in 4 °C Soltran preserving solution for up to 24 h and transplanted into Lewis rat recipients, and the lungs were harvested on day 1 and day 4 after grafting for further analysis. Ischemia-reperfusion injury in the renal allograft caused pulmonary injury following engraftment. PARP-1 (marker for parthanatos) and receptor interacting protein kinase 1 (Rip1) and Rip3 (markers for necroptosis) expression was significantly enhanced in the lung. TUNEL assays showed increased cell death of lung cells. This was significantly reduced after treatment with necrostatin-1 (nec-1) or/and 3-aminobenzamide (3-AB). Acute immune rejection exacerbated the remote lung injury and 3-AB or/and Nec-1 combined with cyclosporine A conferred optimal lung protection. Thus, renal graft injury triggered remote lung injury, likely through regulated necrosis. This study could provide the molecular basis for combination therapy targeting both pathways of regulated necrosis to treat such complications after renal transplantation.

Abstract
A new marine fish cell line, EAGL, derived from the liver of red-spotted grouper Epinephelus akaara was established and characterized. The cells multiplied well in minimum essential medium (MEM) supplemented with 10% foetal bovine serum (FBS) at temperatures between 25 and 30° C. The growth rate of this cell line increased as the proportion of FBS increased from 5 to 20% at 25° C, with maximum growth at the concentration of 15 or 20% FBS. Morphologically, the cells were epithelial-like and the presence of pancytokeratin confirmed their epithelial origin. Chromosome analysis revealed that the modal chromosome number was 48. The susceptibility of the cell line to four fish viruses was tested. Significant cytopathic effect (CPE) was only observed in Singapore grouper iridovirus (SGIV)-infected cells, and the virus replication was further confirmed by immunofluorescence, electron microscopy and real-time reverse-transcription (RT)-PCR assay. When the cells were transfected with pEGFP-N3 plasmid, bright fluorescent signals were observed, suggesting that this cell line can be used for transgenic and genetic manipulation studies.

Abstract
The role of the primary somatosensory cortex in thermal pain perception has been established. However, the cortical circuitry that mediates the thermo-nociceptive information processing has not been elucidated. The aim of present study was to investigate the intracortical synaptic currents in primary somatosensory cortex evoked by short laser pulses and to determine their transmission pathway. Noxious CO2 laser pulse stimuli or innocuous electrical and mechanical stimuli were delivered to the hind paw of halothane-anesthetized rats. Multi-channel field potentials were recorded simultaneously in primary somatosensory cortex and laminar-specific transmembrane currents were analyzed using a current source density method. A distinct spatial-temporal pattern of intra-cortical sink source currents was evoked by laser pulse stimuli. The amplitude of the early component was graded by laser energy output and influenced by contralateral signals, whereas the late components were not intensity-dependent and exhibited bilateral excitation. Intra-cortical current flows revealed that synaptic activation occurred initially at layers IV and VI separately and then was relayed transynaptically to the more superficial and the deeper layers. Latency, amplitude and intracortical distributions of the activated intra-cortical currents evoked by noxious stimuli differed significantly from those evoked by innocuous stimuli. Conduction velocity data together with the results of tetrodotoxin, capsaicin and morphine treatments indicated that the early and late components were mediated separately by A-delta and C fibers. Our results suggest that large and small diameter thermal nociceptive afferents generated laminar-specific intracortical synaptic currents in primary somatosensory cortex and that these excitatory synaptic currents were conveyed separately by lateral and medial thalamic nuclei.

Abstract
We report the 25-year follow-up on the first reported case of odontoma in the middle ear. Diagnosis of odontoma had been made on the basis of radiography films that showed a middle ear mass with multiple toothlike areas of radiopacity. No clinical intervention was recommended. At 25-year follow-up, audiometry showed progressive mixed hearing loss on the affected side and mild ipsilateral sensorineural hearing loss. Computed tomography better characterized the discrete mass, which was shaped similar to a dental crown. To avoid jeopardizing cochlear and facial nerve function, no surgical intervention was pursued, and we recommended use of a BiCROS (bilateral contralateral routing of signal) hearing aid.

Abstract
BACKGROUND Lipoblastoma and lipoblastomatosis are rare pediatric adipose tumors that sometimes affect the neck or spinal cord. This case is the third report of lipoblastoma extending into the spinal canal, the first report of intradural tumor extension, and the first report of hemiparesis resulting from lipoblastoma compressing the spinal cord. METHODS A 13-month-old boy was seen by a pediatrician for a firm, supraclavicular neck mass on the left side. After being evaluated by CT and MRI scanning, the tumor was partially resected. RESULTS Postoperative microscopic examination of the tumor showed adipose cells with mature nuclei and well-formed fat vacuoles interspersed with fibrovascular septa, a finding consistent with maturing lipoblastoma. CONCLUSIONS Although lipoblastomatous tumors are treated with complete surgical resection when possible, location of these tumors in the neck may dictate partial resection to avoid intraoperative injury to the spinal cord.

Abstract
PURPOSE To study the inhibitory effects of synthetic beta peptide on invasion and metastasis of liver cancer. METHODS Membrane-type intercellular adhesion molecule-1 (ICAM-1) expression of SMMC-7721 cultured hepatoma cells (7721 cells) was detected by immunofluorescence cell flowmeter. The adhesion of 7721 cells to fibronectin (FN) was assayed by the MTT method. The adhesion of 7721 cells to 7721 cells, 7721 cells to endothelial cells, and 7721 cells to lymphocyte cells was detected by adhesion assay. LCI-D20 human liver cancer metastasis model in nude mice was used in this experiment. One hundred micrograms of beta peptide per mouse were injected subcutaneously after tumor was resected premetastatically or postmetastatically to observe its effect on liver cancer metastasis after hepatectomy. RESULTS Membrane-type ICAM-1 expression of SMMC-7721 cells treated by beta peptide was lower than that of the untreated cells. The adhesion of 7721 cells to FN, 7721 cells to 7721 cells, 7721 cells to endothelial cells, and 7721 cells to lymphocyte cells was also lower in the beta peptide group than in the untreated group. CONCLUSIONS beta Peptide can block the adhesion of 7721 cells to FN, 7721 cells to some host cells in vitro, and inhibit HCC metastasis of LCI-D20 model posthepatectomy in vivo, so it could potentially act as an antimetastasis drug.

Abstract
AIM To study the effects of cobra venom factor (CVF) on platelets of rat platelet rich plasma (PRP) and to elucidate its cellular mechanism. METHODS PRP was used to measure platelet aggregation and ATP-release simultaneously; prothrombinase, intracellular free calcium, and cAMP were assayed using chromogenic substrate, fluorophor Fura-2, and RIA respectively. RESULTS From 19.5 nmol.L-1 to 617 nmol.L-1 CVF induced platelet aggregation and ATP release concentration-dependently. The ATP release induced by CVF 195 nmol.L-1 was independent of aggregation and was much weaker than that induced by thrombin 1 U/ml. CVF 195 nmol.L-1 increased the prothrombinase activity on platelet surface in a time-dependent manner. SZ-1, SZ-21, and SZ-22, which are monoclonal antibodies against glycoproteins I b/IX, IIIa, and IIb located on platelet membranes, inhibited CVF-induced platelet aggregation. CVF 195 nmol.L-1 also elevated moderately intracellular free calcium ion from (141 +/- 46) to (240 +/- 64) nmol.L-1 in Fura-2 AM loaded platelets, and decreased intracellular cAMP. CONCLUSION Complement activator CVF induced platelet aggregation and ATP release, and increased prothrombinase activity on platelet surface. These actions were dependent on fibrinogen receptors on the platelet surface, elevation in intracellular free calcium ion, and reduction in cAMP.

Abstract
A high performance liquid chromatographic method for the determination of phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylinositol (PI) in the bear bile was established. The air-dried bile of bear was ground into powder and extracted continuously with V(chloroform):V(methanol) = 1:1 to a final dilution 25-fold the volume of the sample. The extract was washed by addition to it of 0.5 its volume of 0.58% aqueous NaCl. The resulting mixture separated into two phases. The lower phase was the total pure lipid extract and was diluted to the desired volume by addition of V(chloroform):V(methanol) = 1:1 mixture and then injected into the HPLC system. The conditions of HPLC were P-E silica column (150 mm x 4.6 mm i.d., 10 microns); V(acetonitrile):V(methanol) = 76:24 mobile phase with a flow rate of 1.5 mL/min and UV detector at 205 nm. The linear regression equation was Y = 5,917X + 1,709(r = 0.9970) for PI, Y = 7,362.1X-6,608.2(r = 0.9949) for PE and Y = 2,457X-2,460.5(r = 0.9972) for PC. The linear range were 1.0-12.0 micrograms, 2.0-24.0 micrograms and 9.5-114.0 micrograms respectively, The relative standard deviation of peaks were 1.6%, 0.89% and 2.6% respectively. The average recovery of PC was 89.30% (RSD = 2.0%). The method enables a simple, rapid and reproducible quantification of PI, PE and PC.

Abstract
BACKGROUND T-cell activation and alteration of cytokines are involved in the pathogenesis of atopic asthma. However, the profile of circulating T-lymphocyte subsets, related cytokines, and plasma IgE during acute asthma attacks is still unclear. OBJECTIVE In an attempt to illustrate the dynamics of these parameters in asthma attacks, we investigated the changes of T-cell subsets, lymphocyte activation, soluble IL-2R, and IgE in peripheral blood in children during and after acute asthma attacks. METHODS This study was carried out in a cohort of Chinese children (n = 59) with acute asthma attacks. Immunoassays were performed when the patients had acute attacks before treatment, and the patients were reexamined in the 4 weeks after the resolution of acute attacks with therapy. Paired t tests were used for the statistical analysis of these patients to compare the data obtained during and after the acute attacks. Twenty healthy, age-matched subjects were used as normal control subjects. Nine children with long-term stable asthma were used as control subjects with stable asthma. RESULTS CD3+, CD4+, CD8+, and IL-2R+ (CD25+) cells; plasma soluble IL-2 receptor; and IgE were significantly higher in patients with acute attacks than in control subjects. (P <.05, P <.05, P <.001, P <.05, P <.0001, and P <.0001, respectively). Immunoelectron microscopy exhibited an increased expression of IL-2R on lymphocytes in acute attacks as compared to control subjects. The abnormalities returned to normal, with the exception of IgE, when clinical remission was achieved after treatment. Correlation analyses revealed a positive relationship between plasma IgE and soluble IL-2R in asthma attacks (r = 0.83, P =.0001). Plasma IgE and soluble IL-2R of those who were in remission positively correlated with their production in acute attacks (r = 0.58, P =.001 and r = 0.71, P =.0001, respectively). CONCLUSION This study suggests that (1) the percentage of CD4+, CD8+, or IL-2R+ lymphocytes in peripheral blood was significantly elevated during acute attacks and returned to normal ranges after complete remission was achieved; (2) plasma soluble IL-2R is a sensitive marker for asthma activity; and (3) atopic asthmatic children seem to have a hereditary predisposition of having higher levels of soluble IL-2R in asthma attacks, coinherited with the trait of IgE.

Abstract
PURPOSE To study the relationship between intercellular adhesion molecule 1 (ICAM-1) and liver cancer metastasis and to find predicting factors that could indicate the growth and metastasis of liver cancer. METHODS ICAM-1 expression in fresh tissue of normal liver and hepatocellular cancer (HCC) was examined by immunoperoxidase staining. Serum soluble intercellular adhesion molecule 1 (sICAM-1) from patients with a benign HCC tumor, and the expression of ICAM-1 in the orthotopically transplanted LCI-D20 tumor of a nude mouse liver cancer metastasis model, and in human hepatoma, the tumor surrounding tissue and normal liver, was analyzed semiquantitatively by the immuno-dot blot method. Tissue ICAM-1 expression (mRNA level) was detected by Northern blotting. RESULTS ICAM-1 expression in LD1-20 D metastatic liver cancer had a positive correlation with tumor size and the time after implantation. It increased suddenly as metastasis occurred being 3.03+/-0.51 before metastasis and 8.24+/-0.95 after metastasis, P < 0.01, then remained high, appending on the number of sites involved (monosite metastasis 5.48+/-0.49, multisite metastasis 10.05+/-1.17, P < 0.05). All six cases of normal liver samples were negative in anti-ICAM-1 immunohistochemical staining, 80.0% (36/45) of the HCC showed some ICAM-1 expression. The rate of positive cells was a little higher in large tumors, tumors with an intact capsule and tumors with metastasis, but there was no significant difference. It was noticed that two cancer emboli also had high ICAM-1 expression. The ICAM-1 concentration in HCC (13.43+/-0.09) was higher than that in tumor surrounding the liver (5.89+/-0.17, P < 0.01) and that in normal liver (4.27+/-0.21, P < 0.01). sICAM-1, like tissue ICAM-1, was higher in HCC patients than in patients (with benign liver tumor and normal controls. Both tissue ICAM-1 and sICAM-1 were higher in the metastasis group than in the group without metastasis (tissue ICAM-1 20.24+/-0.30 vs 10.23+/-0.12 P < 0.05; sICAM-1 12.18+/-0.25 vs 9.77+/-0.54 P < 0.05). Northern blot analysis revealed that ICAM-1 expression, as indicated by mRNA level, was also higher in HCC and in cancer emboli than in tumor surrounding liver and normal liver. CONCLUSIONS Tissue ICAM-1 and serum sICAM-1 could indicate the stage of HCC, and the potential of hepatoma cells for invasion and metastasis. They may play an important role in the metastasis cascade.

Abstract
We studied the Ca2+ movement induced by activation of alpha1A-, alpha1B- and alpha1D-adrenoceptor subtypes in transfected HEK-293 cells with the fura-2 probe. All these alpha1-AR subtypes induced both Ca2+ release and Ca2+ entry. The effect on Ca2+ release in alpha1b transfected HEK-293 cells was bigger than that in alpha1a and alpha1d transfected HEK-293 cells, and the effects on Ca2+ entry were the same in alpha1a, alpha1b and alpha1d transfected HEK-293 cells. The Ca2+ entry was inhibited by 1 mM NiSO4, but not by nifedipine. Cyclopiazonic acid (CPA) produced a biphasic Ca2+ signal response in Ca2+ medium, and only induced a transient response in Ca2+-free medium. After depletion of CPA-sensitive Ca2+ pool by 10 microM CPA in Ca2+-free medium, 10 microM adrenaline (Adr) still transiently increased [Ca2+]i in three different alpha1-adrenoceptor subtype transfected HEK-293 cells. However, after depletion of adrenaline-sensitive Ca2+ pool by 10 microM Adr, CPA transiently elevated [Ca2+]i only in alpha1a and alpha1d transfected HEK-293 cells, not in alpha1b transfected HEK-293 cells. U73122, a phospholipase C (PLC) inhibitor, inhibited both Ca2+ release and Ca2+ entry induced by activation of alpha1A alpha1B and alpha1D subtypes in transfected HEK-293 cells. These results suggest that HEK-293 cell line contains two functionally separate intracellular Ca2+ pools, CPA-sensitive and Adr-sensitive pools. Activation of alpha1B-AR stimulates Ca2+ release from both CPA-sensitive and Adr-sensitive Ca2+ pools. Alpha1A and alpha1D subtypes induce Ca2+ release only from Adr-sensitive Ca2+ pool.
