Abstract
Objectives: To explore the efficacy and safety of laparoscopic radical gastrectomy after neoadjuvant chemotherapy combined with immunotherapy and targeted therapy in patients with gastric cancer. Methods: A retrospective analysis of clinical and pathological data of 20 patients with locally advanced gastric cancer (clinical TNM stage T3-4aN+M0) admitted to the Cancer Hospital, Chinese Academy of Medical Sciences from July 2021 to July 2023. All patients received 3 cycles of SOX (Oxaliplatin+S-1) regimen combined with immunotherapy (Trastuzumab) and targeted therapy (Apatinib) as neoadjuvant treatment followed by laparoscopic radical gastrectomy for gastric cancer. Surgical outcomes, postoperative pathological response, and postoperative recovery were observed. Quantitative data, except for age and operation time, were expressed using Median (range). Results: Among the 20 patients, there were 18 males and 2 females, aged 41 to 73 years [(60.6±9.7) years]. All 20 patients underwent laparoscopic surgical treatment after neoadjuvant therapy, with one patient undergoing laparoscopic conversion to open total gastrectomy with partial transverse colon resection due to tumor invasion into the transverse mesocolon. Eight patients underwent totally laparoscopic radical gastrectomy, all with Billroth Ⅱ+Braun anastomosis at the distal stomach. Eleven patients underwent laparoscopic-assisted radical gastrectomy, among which total gastrectomy with Roux-en-Y anastomosis was performed in ten cases, and proximal gastrectomy with esophagogastrostomy overlap anastomosis was performed in one case. The mean operation time for the 20 patients was (165.0±34.1) minutes; intraoperative blood loss was 80 (20-100) ml; and the number of lymph nodes retrieved was 68 (21-89). Postoperative pathological TNM staging revealed stage T0N0M0 in six cases, stage Ⅰ in two cases, stage Ⅱ in three cases, and stage Ⅲ in nine cases. Six patients (30.0%) achieved pathological complete response, and nine patients (45.0%) achieved significant pathological response. The median postoperative time to flatus was 4 (1-5) days; oral intake resumed after 3 (2-5) days; and the median length of hospital stay was 13 (6-19) days. One patient developed colonic anastomotic leakage with intra-abdominal infection, and one patient developed duodenal stump leakage with intra-abdominal infection, both classified as Clavien-Dindo grade 3A complications, and improved after treatment and discharged. One patient developed gastric paresis, and two patients developed pleural effusion, classified as Clavien-Dindo grade 2 complications, and improved after treatment and discharged. There were no deaths within 30 days after discharge. Conclusions: Laparoscopic radical gastrectomy for gastric cancer after neoadjuvant treatment with the SOX regimen combined with immunotherapy and targeted therapy is safe and feasible, with satisfactory short-term efficacy. However, there is an increase in overall surgical risk and difficulty, and it is recommended to be performed in experienced gastric cancer centers.

Abstract
Objective: Quantified MRCP imaging data was used as a reference for design and preparation of a modified percutaneous transhepatic cholangio drainage (PTCD) tube. Methods: 3.0 T upper abdominal MR and MRCP imaging data of 2 300 patients treated from July 2015 to July 2020 at the Department of Radiology of the Affiliated Cancer Hospital of Zhengzhou University were screened and a total of 381 patients diagnosed with biliary duct structures were identified. Causative etiologies among these patients included pancreatic adenocarcinoma (pancreatic head), cholangiocarcinoma, ampullary carcinoma, as well as intrahepatic and/or extrahepatic bile duct dilation. An improved PTCD tube was designed based on MRCP quantification of left and right hepatic and common hepatic duct length. Results: In the setting of biliary obstruction caused by malignancy, the distance of the left hepatic duct from its origin to the point of left and right hepatic duct confluence was 15.9±3.8 mm, while the distance of the right hepatic duct from its origin to the point of left and right hepatic duct confluence was 12.4±3.2 mm; the length of the bile duct from its origin to the point of left and right hepatic duct confluence was 34.0±8.1 mm. The improved PTCD tube design incorporated an altered length of the drainage orifice. Conclusion: MRCP imaging of the biliary tract is effective for measuring biliary tract length in the setting of pathological dilation. Based on our biliary tract measurements, a modified PTCD tube was designed to more effectively meet drainage requirements and manage biliary obstruction caused by Bismuth-Corlette type Ⅱ and Ⅲ malignancies.

Abstract
BACKGROUND Premature ovarian insufficiency is common in clinically infertile patients. The NOD-like receptor family pyrin domain-containing 3 (NLRP3)/Gasdermin D (GSDMD) signaling pathway plays a key role in premature ovarian insufficiency. Leonurine (Leo) is one of the important active ingredients extracted from Leonurus japonicus Houttuyn, which can inhibit NLRP3 activation. However, whether leonurine hydrochloride plays a protective role in premature ovarian insufficiency through actions on NLRP3/GSDMD signaling is not yet known. METHODS After cyclophosphamide-induced premature ovarian insufficiency was established in female mice, Leo was injected intraperitoneally over four weeks to evaluate the ovarian function and anti-pyroptosis effects using the metrics of fertility, serum hormone level, ovary weight, follicle number, expression of NLRP3/GSDMD pathway-related proteins, and serum IL-18 and IL-1β levels. RESULTS Intraperitoneal administration of leonurine hydrochloride was found to significantly protect fertility and maintain both serum hormone levels and follicle number in mice with premature ovarian insufficiency. Mice treated with leonurine hydrochloride consistently resisted cyclophosphamide-induced ovarian damage by inhibiting the activation of NLRP3 inflammasome, Caspase-1 and GSDMD in both ovarian tissue and granulosa cells, which led to lower levels of IL-18 and IL-1β in the serum (p < 0.05, p < 0.01, p < 0.001). CONCLUSION Intraperitoneal administration of leonurine hydrochloride prevents cyclophosphamide-induced premature ovarian insufficiency in mice by inhibiting NLRP3/GSDMD-mediated pyroptosis.

Abstract
Acquired immunodeficiency syndrome (AIDS) caused by Human immunodeficiency virus type 1 (HIV-1) has a high tendency among illicit drug abusers. Recently, it is reported that abuse of fentanyl, a potent synthetic μ receptor-stimulating opioid, is an independent risk factor for HIV-1 infection. However, the mechanism of action in augmenting HIV-1 infection still remains elusive. In this study, we found that fentanyl enhanced infection of HIV-1 in MT2 cells, primary macrophages and Jurkat C11 cells. Fentanyl up-regulated CXCR4 and CCR5 receptor expression, which facilitated the entry of virion into host cells. In addition, it down-regulated interferon-β (IFN-β) and interferon-stimulated genes (APOBEC3F, APOBEC3G and MxB) expression in MT2 cells. Our findings identify an essential role of fentanyl in the positive regulation of HIV-1 infection via the upregulation of co-receptors (CXCR4/CCR5) and downregulation of IFN-β and ISGs, and it may have an important role in HIV-1 immunopathogenesis.

Abstract
BACKGROUND At present, there is insufficient medical evidence to determine whether adjuvant chemotherapy is necessary for T2N0M0 gastric cancer.
AIM To obtain a risk score to assess the need for adjuvant chemotherapy in patients with T2N0M0 gastric cancer.
METHODS We identified 325 patients with pathological T2N0M0 stage primary gastric cancer at the National Cancer Center between 2011 and 2018. Univariate and multivariate Cox regression analyses were performed to predict factors affecting prognosis. Vascular invasion, tumor site, and body mass index were assessed, and a scoring system was established. We compared the survival outcomes and benefits of adjuvant chemotherapy between the different subgroups.
RESULTS Five-year survival rates of the score 0, 1, 2, and 3 groups were 92%, 95%, 80%, and 50%, respectively (P < 0.001). In the score 2-3 group, five-year survival rates for patients in the adjuvant chemotherapy group and postoperative observation group were 95% and 61%, respectively (P = 0.021).
CONCLUSION For patients with T2N0M0 stage gastric cancer and two or more risk factors, adjuvant chemotherapy after D2 gastrectomy may have a survival benefit.

Abstract
BACKGROUND For Siewert type II/III adenocarcinoma of gastroesophageal junction (AGE), the efficacy of adjuvant chemoradiotherapy (CRT) after D2/R0 resection remains uncertain.
AIM To determine whether CRT was superior to chemotherapy (CT) alone after D2/R0 resection for locally advanced Siewert type II/III AGE.
METHODS We identified 316 locally advanced Siewert type II/III AGE patients who were treated with D2/R0 resection at National Cancer Center from 2011 to 2018. 57 patients received adjuvant CRT and 259 patients received adjuvant CT. We followed patients for overall survival (OS), relapse-free survival, and recurrence pattern.
RESULTS Five-year OS rates of the CRT group and the CT group for all patients were 66.7% and 41.9% (P = 0.010). Five-year OS rates of the CRT group and the CT group for Siewert type III AGE patients were 65.7% and 43.9% (P = 0.006). Among the 195 patients whose recurrence information could be obtained, 18 cases (34.6%) and 61 cases (42.7%) were diagnosed as recurrence in the CRT group and CT group, respectively. The local and regional recurrence rates in the CRT group were lower than that in the CT group (22.2% vs 24.6%, 27.8% vs 39.3%). Multivariable cox regression analysis showed that vascular invasion, nerve invasion, and adjuvant CRT were important prognostic factors for Siewert type III AGE.
CONCLUSION For locally advanced Siewert type III AGE, adjuvant CRT may prolong OS and reduce the regional recurrence rate.

Abstract
OBJECTIVE To investigate the evolution of blood separation results by gel extraction of multiple myeloma (MM) patients, and to evaluate the clinical value of abnormal blood separation results for the evaluation of disease and prognosis. METHODS The clinical data of 5 patients diagnosed newly MM patients with abnormal blood separation of gel collection vessels in our hospital were retrospectively analyzed, and the changes of blood separation results and blood index levels were followed up with the improvement of treatment effect, and the correlation of different blood index levels was analyzed. RESULTS In 5 patients with newly diagnosed MM, the blood separation result showed floating phenomenon after centrifugation, which divided into three layers and the order from top to bottom is separator gel, serum, and red blood cells(RBC). With partial remission of clinical symptoms, the blood separation results were still abnormal, which were divided into three layers from top to bottom: serum, RBC and separator gel. Finally, with complete remission of the disease, blood separation results returned to normal, from top to bottom: serum, separator gel, RBC. With the blood separation results from abnormal to normal, the blood routine indicators: Hb, Hct levels gradually increased, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR) gradually decreased; biochemical indexes: TP, GLB, Ig and β2-MG levels gradually decreased. Tumor load related indicators: serum IL-6, TNF-α, IL-17 levels gradually decreased, and IL-35 levels gradually increased; and the differences were statistically significant (P<0.05). Pearson correlation analysis showed that serum β2-MG was positively correlated with IL-6, TNF-α and IL-17 levels (r=0.710, 0.756, 0.581, P<0.05), and negatively correlated with IL-35 level (r=-0565, P<0.05). CONCLUSION Abnormal blood separation exists in MM patients, and there are significant differences in blood, tumor load and immune balance related indexes in patients with different blood separation results, which provides partial experimental basis for evaluation of disease, efficacy and prognosis with different blood separation results.

Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) has drawn increasing attention over the years. Although LTG has shown surgical benefits compared to open TG (OTG) in early stage gastric cancer (GC), little is known about the surgical and oncological outcomes of LTG for advanced GC following neoadjuvant therapy (NAT).
AIM To compare the long- and short-term outcomes of advanced GC patients who underwent LTG vs OTG following NAT.
METHODS Advanced GC patients who underwent TG following NAT between April 2011 and May 2018 at the Cancer Hospital of the Chinese Academy of Medical Sciences were enrolled and stratified into two groups: LTG and OTG. Propensity score matching analysis was performed at a 1:1 ratio to overcome possible bias.
RESULTS In total, 185 patients were enrolled (LTG: 78; OTG: 109). Of these, 138 were paired after propensity score matching. After adjustment for propensity score matching, baseline parameters were similar between the two groups. Compared to OTG, LTG was associated with a significantly shorter length of hospital stay (P = 0.012). The rates of R0 resection, lymph node harvest, and postoperative morbidity did not significantly differ between the two groups. Overall survival (OS) outcomes were comparable between the two groups. Pathological T and N stages were found to be independent risk factors for OS.
CONCLUSION LTG can be a feasible method for advanced GC patients following NAT, as it appears to be associated with better short- and comparable long-term outcomes compared to OTG.

Abstract
BACKGROUND For advanced gastric cancer patients with pancreatic head invasion, some studies have suggested that extended multiorgan resections (EMR) improves survival. However, other reports have shown high rates of morbidity and mortality after EMR. EMR for T4b gastric cancer remains controversial.
AIM To evaluate the surgical approach for pT4b gastric cancer with pancreatic head invasion.
METHODS A total of 144 consecutive patients with gastric cancer with pancreatic head invasion were surgically treated between 2006 and 2016 at the China National Cancer Center. Gastric cancer was confirmed in 76 patients by postoperative pathology and retrospectively analyzed. The patients were divided into the gastrectomy plus en bloc pancreaticoduodenectomy group (GP group) and gastrectomy alone group (GA group) by comparing the clinicopathological features, surgical outcomes, and prognostic factors of these patients.
RESULTS There were 24 patients (16.8%) in the GP group who had significantly larger lesions (P < 0.001), a higher incidence of advanced N stage (P = 0.030), and less neoadjuvant chemotherapy (P < 0.001) than the GA group had. Postoperative morbidity (33.3% vs 15.3%, P = 0.128) and mortality (4.2% vs 4.8%, P = 1.000) were not significantly different in the GP and GA groups. The overall 3-year survival rate of the patients in the GP group was significantly longer than that in the GA group (47.6%, median 30.3 mo vs 20.4%, median 22.8 mo, P = 0.010). Multivariate analysis identified neoadjuvant chemotherapy [hazard ratio (HR) 0.290, 95% confidence interval (CI): 0.103–0.821, P = 0.020], linitis plastic (HR 2.614, 95% CI: 1.024–6.675, P = 0.033), surgical margin (HR 0.274, 95% CI: 0.102–0.738, P = 0.010), N stage (HR 3.489, 95% CI: 1.334–9.120, P = 0.011), and postoperative chemoradiotherapy (HR 0.369, 95% CI: 0.163–0.836, P = 0.017) as independent predictors of survival in patients with pT4b gastric cancer and pancreatic head invasion.
CONCLUSION Curative resection of the invaded pancreas should be performed to improve survival in selected patients. Invasion of the pancreatic head is not a contraindication for surgery.

Abstract
BACKGROUND The association between body mass index (BMI) and clinical outcomes remains unclear among patients with resectable gastric cancer.
AIM To investigate the relationship between BMI and long-term survival of gastric cancer patients.
METHODS This retrospective study included 2526 patients who underwent radical gastrectomy for gastric cancer between September 2013 and June 2018. The patients were divided into four groups: Group A (low BMI, < 18.5 kg/m2), group B (normal BMI, 18.5-24.9 kg/m2), group C (overweight, 25-29.9 kg/m2), and group D (obese, ≥ 30 kg/m2). Clinicopathological findings and survival outcomes were recorded and analyzed.
RESULTS Preoperative weight loss was more common in the low-BMI group, while diabetes was more common in the obese group. Upper-third gastric cancer accounted for a large proportion of cases in the higher BMI groups. Major perioperative complications tended to increase with BMI. The 5-year overall survival rates were 66.4% for group A, 75.0% for group B, 77.1% for group C, and 78.6% for group D. The 5-year overall survival rate was significantly lower in group A than in group C (P = 0.008) or group D (P = 0.031). Relative to a normal BMI value, a BMI of < 18.5 kg/m2 was associated with poor survival (hazard ratio: 1.558, 95% confidence interval: 1.125-2.158, P = 0.008).
CONCLUSION Low BMI, but not high BMI, independently predicted poor survival in patients with resectable gastric cancer.

Abstract
BACKGROUND Afferent loop syndrome (ALS) is a rare mechanical complication that occurs after reconstruction of the stomach or esophagus to the jejunum, such as Billroth II gastrojejunostomy, Roux-en-Y gastrojejunostomy, or Roux-en-Y esophagoje-junostomy. Traditionally, an operation is the first choice for benign causes. However, for patients in poor physical condition who experience ALS soon after R0 resection, the type of treatment remains controversial. Here, we present an efficient conservative method to treat ALS.
CASE SUMMARY Case 1 was a 69-year-old male patient who underwent total gastrectomy with Roux-en-Y jejunojejunostomy. On postoperative day (POD) 10 he developed symptoms of ALS that persisted and increased over 1 wk. Case 2 was a 59-year-old male patient who underwent distal gastrectomy with Billroth II gastrojejunostomy. On postoperative day POD 9 he developed symptoms of ALS that persisted for 2 wk. Both patients underwent fluoroscopic-guided nasointestinal tube placement with maintenance of continuous negative pressure suction. Approximately 20 d after the procedure, both patients had recovered well and were discharged from hospital after removal of the tube. At 3-mo follow-up, there were no signs of ALS in these two patients.
CONCLUSION This is the first report of treating postoperative ALS by fluoroscopic-guided nasointestinal tube placement. Our cases demonstrate that this procedure is an effective and safe method to treat ALS that relieves patients’ symptoms and avoids complications caused by other invasive procedures.

Abstract
The coronavirus disease 2019 pandemic has become a major global public health problem. Governments are taking the necessary steps to reduce the movement of people to contain the spread of the virus. However, these measures have caused considerable distress to patients with gastric cancer who are newly diagnosed or are undergoing treatment. In addition to the cancer, they must deal with longer waiting times for surgery and poor communication with doctors. Furthermore, gastric cancer patients generally have low immunity and a poor nutritional status, so they are a high-risk group for infection with the novel coronavirus. Therefore, it is necessary to formulate reasonable outpatient management strategies to reduce the adverse effects of the pandemic on their treatment. We summarize the management strategies for patients with gastric cancer during the pandemic.

Abstract
Opioid abuse alters the functions of immune cells in both in vitro and in vivo systems, including macrophages. Here, we investigated the effects of methadone, a widely used opioid receptor agonist for treatment of opiate addiction, on the expression of intracellular viral restriction factors and HIV replication in primary human macrophages. We showed that methadone enhanced the HIV infectivity in primary human macrophages. Mechanistically, methadone treatment of macrophages reduced the expression of interferons (IFN-β and IFN-λ2) and the IFN-stimulated anti-HIV genes (APOBEC3F/G and MxB). In addition, methadone-treated macrophages showed lower levels of several anti-HIV microRNAs (miRNA-28, miR-125b, miR-150, and miR-155) compared to untreated cells. Exogenous IFN-β treatment restored the methadone-induced reduction in the expression of the above genes. These effects of methadone on HIV and the antiviral factors were antagonized by pretreatment of cells with naltrexone. These findings provide additional evidence to support further studies on the role of opiates, including methadone, in the immunopathogenesis of HIV disease.

Abstract
Hantaviruses can cause hemorrhagic fever with renal syndrome (HFRS) in Eurasia and have led to public health threat in China. The pathogenesis of HFRS is complex and involves capillary leakage due to the infection of vascular endothelial cells. Accumulating evidence has demonstrated that hantavirus can induce apoptosis in many cells, but the mechanism remains unclear. Our studies showed that Hantaan virus (HTNV) infection could induce TNF-related apoptosis-inducing ligand (TRAIL) expression in primary human umbilical vein endothelial cells (HUVECs) and sensitize host cells toward TRAIL-mediated apoptosis. Furthermore, TRAIL interference could inhibit apoptosis and enhance the production of HTNV as well as reduce IFN-β production, while exogenous TRAIL treatment showed reverse outcome: enhanced apoptosis and IFN-β production as well as a lower level of viral replication. We also observed that nucleocapsid protein (NP) and glycoprotein (GP) of HTNV could promote the transcriptions of TRAIL and its receptors. Thus, TRAIL was upregulated by HTNV infection and then exhibited significant antiviral activities in vitro, and it was further confirmed in the HTNV-infected suckling mice model that TRAIL treatment significantly reduced viral load, alleviated virus-induced tissue lesions, increased apoptotic cells, and decreased the mortality. In conclusion, these results demonstrate that TRAIL-dependent apoptosis and IFN-β production could suppress HTNV replication and TRAIL treatment might be a novel therapeutic target for HTNV infection.

Abstract
The outbreak of COVID-19 occurred in Wuhan, Hubei province of China, at the end of 2019, and spread rapidly across the country. After the outbreak of this disease, the overwhelming majority of cities have launched the "first level response" and the regular diagnosis and treatment of cancer patients are greatly affected. The digestive systemic cancer is the most common malignancy. Most patients are diagnosed in the advanced stage with poor prognosis. The epidemic of COVID-19 poses new challenges to diagnosis and treatment of the patients with digestive system malignancies. Based on the fully understanding of the characteristics of digestive system tumors, we should change the treatment strategy and adopt more reasonable treatment strategy timely during the epidemic period to minimize the adverse effects of the epidemic of COVID-19 on the treatment.

Abstract
Immune repertoire refers to the sum of T cells and B cells with functional diversity in the circulatory system of one individual at any given time. Immune repertoire sequencing aims to study T and B lymphocytes, evaluate the diversity of the immune system, and dig deeper into the relationship between immune repertoire and diseases, using multiple polymerase chain reaction or rapid amplification of 5' cDNA ends to amplify the complementary determining regions that determine the diversity of B cell receptors or T cell receptors as well as high-throughput sequencing and data analysis. Recently, immune repertoire has been widely studied in the identification of biomarkers and therapeutic targets, efficacy monitoring, and prognosis analysis in cancer. This paper reviews the progress in the research of immune repertoire of digestive system tumors.

Abstract
Three new triterpenoids, mallomacrostins A-C (1-3), and 11 known ones (4-14) were obtained from the twigs and leaves of Mallotus macrostachyus. Mallomacrostin A possessed a new trinor-D:B-friedobaccharane skeleton. The structures of the new compounds were elucidated on the basis of extensive spectroscopic techniques including HR-ESIMS and NMR and the structure of 1 was confirmed by single crystal X-ray diffraction analysis. Spectroscopic data of the known compound 4 were provided for the first time. Compounds 2 and 10 exhibited significant anti-inflammatory activity by inhibiting LPS-induced release of nitric oxide with IC50 of 70.0 μM and 14.0 μM, respectively.

Abstract
Objective: To evaluate the clinical characteristics and the corresponding MRI and laboratory findings in patients with neuromyelitis optica spectrum disorder (NMOSD) associated with area postrema (AP). Methods: The study was a retrospective analysis of data from 120 NMOSD patients, and 18 cases were with AP out of these patients, The clinical presentation, MRI changes, serological markers and treatment outcome were reported. Results: AP occurred in 18 patients (15%, 18/120). AP was the onset symptom in 14 (14/18) patients and 3 days to 7 months (median 40 days) later, optic neuritis or myelitis was involved. One patient presented AP after optic neuritis. Three patients (3/18) had AP and myelitis or optic neuritis simultaneously. AP symptom presented as intractable nausea and vomiting, hiccups. Compared to the patients without AP (n=102), the patients with AP (n=18) had shorter duration and fewer numbers of optic neuritis(P<0.05). There was no statistical difference in sex, onset age, course of disease (relapsing or monophasic) and EDSS scores (P>0.05). The MRI revealed flake or linear lesions in medulla. Twelve patients had cervical cord lesions extending to medulla lesions (12/18). Eleven patients had long cord lesions extending more than 3 spinal cords. The AQP4-antibody did not differ in patients with or without AP (14/18 vs 75/102). The symptom of AP was successfully relieved with methylprednisolone. Conclusion: AP symptoms/signs are common in patients with NMOSD. Vomiting and hiccups can be the first symptoms. The medulla lesions and the lesions extending to upper cervical cord are unique to NMOSD. Awareness of AP presentations is helpful for early diagnosis and proper treatment to prevent further disability.

Abstract
Purpose The effect of glucocorticoid(s) on connective tissue disease (CTD)-related interstitial lung disease (ILD) is controversial. This multicenter study aimed to identify glucocorticoid-sensitive patients using a radiomics approach. Methods A total of 416 CTD-ILD patients who began glucocorticoid treatment at the discretion of the attending physician, with or without cyclophosphamide, were included in this study. High doses were defined as pulsed intravenous methylprednisolone, an initial dose of 1 mg/kg/day of prednisolone or 0.8 mg/kg/day of methylprednisolone. Low doses were defined as those less than high doses. Radiomics features were manually extracted from primary lung lesions delineated on computed tomography images, and selected by variance, univariate feature selection, and least absolute shrinkage and selection operator regression model. The prediction models were developed using data from 309 patients from two centers and externally validated in 107 patients from four other hospitals. Results Treatment response in the training and validation groups was 38.5% and 36.4%, respectively. Eleven radiomics features were selected from 1,029 features with predictive value. Random forest models built for radiomics features to predict treatment response yielded a sensitivity of 0.897. The calibration curve of a nomogram demonstrated good agreement between prediction and observation. Decision curve analysis indicated that glucocorticoid was beneficial if the predicted response rate was 50%–60% for an individual. High doses of glucocorticoids and cyclophosphamide yielded superior efficacy. Conclusion Radiomics-based predictive models reliably identified glucocorticoid-sensitive CTD-ILD patients. Short-term, high-dose glucocorticoid with cyclophosphamide yielded promising results as a potential therapy.

Abstract
BACKGROUND/AIMS Pterygium is a common ocular surface disease with an unknown etiology and threatens vision as it invades into the cornea. Circular RNAs (circRNAs) are a novel class of RNA transcripts that participate in several physiological and pathological processes. However, the role of circRNAs in pathogenesis of pterygium remains largely unknown. METHODS Genome-wide circRNA expression profiling was performed to identify pterygium -related circRNAs. GO analysis, pathway analysis, and miRNA response elements analysis was performed to predict the function of differentially expressed circRNAs in pterygium. MTT assays, Ki67 staining, Transwell assay, Hoechst 33342 staining, and Calcein-AM/PI staining were performed to determine the effect of circRNA silencing on pterygium fibroblast and epithelial cell function. RESULTS Approximately 669 circRNAs were identified to be abnormally expressed in pterygium tissues. GO analysis demonstrated that the host genes of differentially expressed circRNAs were targeted to extracellular matrix organization (ontology: biological process), cytoplasm (ontology: cellular component), and protein binding (ontology: molecular function). Pathway analysis showed that dysregulated circRNAs-mediated regulatory networks were mostly enriched in focal adhesion signaling pathway. Notably, circ_0085020 (circ-LAPTM4B) was shown as a potential biomarker for pterygium. circ_0085020 (circ-LAPTM4B) silencing affected the viability, proliferation, migration, and apoptosis of pterygium fibroblast and epithelial cells in vitro. CONCLUSIONS This study provides evidence that circRNAs are involved in the pathogenesis of pterygium and might constitute promising targets for the therapeutic intervention of pterygium.

Abstract
Objective: To investigate the value of split hand in the differential diagnosis of amyotrophic lateral sclerosis(ALS) and cervical spondylotic amyotrophy (CSA). Methods: A total of 62 ALS patients, 57 CSA patients and 65 normal controls who visited the Neurology and Spine Department of Beijing Jishuitan Hospital from May 2013 to June 2017 were enrolled into this study.The amplitudes of compound muscle action potentials (CMAP) were recorded from abductor digiti minimi (ADM) and abductor pollicis brevis (APB). Moreover, the ratio of CMAP amplitude between ADM and APB (ADM/APB) was calculated. Results: The ADM/APB of the ALS group (1.93±1.97)was significantly higher than that of the normal control group (0.92±0.22)(P<0.05); the ADM/APB of the CSA group (0.74±0.32)was significantly lower than that of the normal control group (0.92±0.22)(P<0.05); the ADM/APB of the ALS group (1.93±1.97)was significantly higher than that of the CSA group(0.74±0.32)(P<0.05); the areas under receiver operator characteristic curve in patients with ALS was 0.843, the diagnostic sensitivity and specificity for ALS were 75.8% and 83.1% with the cutoff value of ADM/APB=1.077; the areas under receiver operator characteristic curve in patients with CSA was 0.737, the diagnostic sensitivity and specificity for CSA were 64.9% and 87.1% with the cutoff value of ADM/APB=0.739. Conclusion: The ADM/APB has certain clinical value for the differentiation of ALS and CSA.

Abstract
BACKGROUND Caspase-3 is a potential marker of apoptosis. We investigated whether serum caspase-3 concentrations were increased and its association with severity and prognosis after intracerebral hemorrhage (ICH). METHODS This prospective clinical study recruited 112 ICH patients and 112 healthy individuals. Serum was assayed for caspase-3 using enzyme-linked immunosorbent assay. Stroke severity was quantified by National Institute of Health Stroke Scale (NIHSS) and hematoma volume. Six-month outcome was measured by modified Rankin Scale. Analyses were performed using univariate and multivariate analyses. RESULTS Patients had significantly higher serum caspase-3 concentrations than controls. Capase-3 concentrations correlated with NIHSS score and hematoma volume. Serum caspase-3 emerged as an independent predictor for 6-month mortality and bad prognosis (modified Rankin scale score>2). Based on receiver operating characteristic curve, caspase-3 concentrations showed similar prognostic value when compared with NIHSS score and hematoma volume. CONCLUSION Serum caspase-3 concentrations are increased in ICH patients as well as correlate with clinical severity and prognosis.

Abstract
BACKGROUND In mainland China, awareness of disease of elderly cancer patients largely relies on the patients' families. We developed a staged procedure to improve their awareness of disease. MATERIALS AND METHODS Participants were 224 elderly cancer patients from 9 leading hospitals across Southern China. A questionnaire was given to the oncologists in charge of each patient to evaluate the interaction between family and patients, patient awareness of their disease and participation in medical decision-making. After first cycles of treatment, increased information of disease was given to patients with cooperation of the family. Then patient awareness of their disease and participation in medical decision-making was documented. RESULTS Among the 224 cancer elderly patients, 26 (11.6%) made decisions by themselves and 125 (55.8%) delegated their rights of decision- making to their family. Subordinate family members tended to play a passive role in decision-making significantly. Patients participating more in medical decision-making tended to know more about their disease. However, in contrast to the awareness of disease, patient awareness of violation of medical recommendations was reversely associated with their participation in medical decision-making. Improvement in awareness of diagnosis, stages and prognosis was achieved in about 20% elderly cancer patients. About 5% participated more actively in medical decision-making. CONCLUSIONS Chinese elderly cancer patient awareness of disease and participation in medical decision-making is limited and relies on their family status. The staged procedure we developed to improve patient awareness of disease proved effective.

Abstract
Statin withdrawal is associated with deleterious outcome on stroke patients. Whether risk changes over time, depends on concomitant treatment of intravenous thrombolysis, or both remains to be clarified. We assessed the influence of statin withdrawal within 3 weeks while initiated in acute phase (72 hours) among patients receiving intravenous thrombolysis.This was a monocentered retrospective observational study enrolling intravenous thrombolytic stroke patients from June 2009 to May 2014. Consecutive patients were distinguished into 3 groups according to the initiation and withdrawal of statin: the reference group (not received statin in 72 hours after stroke onset); the continued group (initiated statin therapy in 72 hours and continued for at least 3 weeks); the withdrawal group (initiated statin in 72 hours and discontinued within 3 weeks). All reasons for cessation were recorded. The effects of statin withdrawal on short-, mid-, and long-term outcomes were evaluated as neurologic improvement (NIH Stroke Scale [NIHSS] score improvement ≥4 from baseline or later NIHSS = 0), death or poor outcome (modified Rankin Scale [mRS] ≥4), and favorable outcome (mRS ≤2). We further evaluate statin withdrawal effects in cardioembolic stroke patients for these outcomes.Among 443 IVT patients enrolled, 367 were included in the final study population. There were 88, 188, and 91 patients in the reference, continued, and withdrawal groups, respectively. Multivariable logistic regression showed that statin withdrawal compared with the reference was related to a lower possibility of long-term favorable outcome (OR = 0.45, 95% CI [0.22, 0.90], P = 0.024). Compared with the continued group, the adjusted OR of statin withdrawal was 0.40 (95% CI [0.22, 0.72], P = 0.002) and 2.52 (95% CI [1.34, 4.75], P = 0.004) for long-term favorable and poor/death outcomes, respectively. Also, results were similar for cardioembolic stroke patients (OR = 0.35, 95% CI [0.14, 0.89], P = 0.027 of favorable outcome and OR = 3.62, 95% CI [1.37, 9.62], P = 0.010 of poor/death outcome).In a real-world setting, for stroke patients receiving intravenous thrombolysis, statin withdrawal within 3 weeks initiating in 72 hours may have a harmful effect on the long-term neurologic outcome, even in cardioembolic stroke patients.

Abstract
PURPOSE The purpose of this paper is to describe ophthalmic findings in a family with isolated ectopia lentis (EL) caused by a specific FBN1 mutation. METHODS Detailed family histories and clinical data were recorded for six isolated EL patients of 11 family members. The ophthalmological and systematic examinations were performed on patients and unaffected members of the investigated family. The detailed ocular examinations included visual acuity, anterior chamber depth, pupil size, lens location, optometry, central corneal thickness, keratometry, slitlamp examination, fundus examination, axial length, ocular B-ultrasound, gonioscope checking, ultrasound biomicroscopy (UBM) and intraocular pressure (IOP; Goldmann applanation tonometer). Systematic examinations included the measurement of echocardiogram, height, arm span, skull, face, jaw, tooth, breast bone, spinal column, and skin. Genomic DNA was extracted using the phenol-chloroform extraction method for all subjects, and sequencing was carried out on an ABI Prism 3730 Genetic Analyzer. RESULTS A heterozygous mutation, c.184C>T (p.Arg62Cys) in exon 2 of FBN1 was identified in all affected members but was not found in any unaffected member of the family. Our study presented detailed clinical manifestations, including some novel ophthalmic findings, such as pupillary abnormality, different types of glaucoma, and progressive hyperopia. CONCLUSIONS Ophthalmic findings and the p.Arg62Cys mutation of FBN1 gene were reported in a family with early-onset isolated ectopia lentis.

Abstract
OBJECTIVES This study aimed to investigate the relationship between serum tau concentrations and 3-month clinical outcomes in patients with intracerebral hemorrhage. DESIGN AND METHODS Serum tau concentrations of 176 patients were quantified by enzyme-linked immunosorbent assay. The end points were mortality and poor outcome (modified Rankin Scale score>2) after 3 months. RESULTS 110 patients (62.5%) had a poor outcome at 3 months. The 3-month mortality rate was 36.4% (64/176). A forward stepwise logistic regression selected serum tau concentration as an independent predictor for 3-month mortality (P=0.002) and poor outcomes (P=0.009) of patients. A receiver operating characteristic curve analysis showed that serum tau concentration predicted 3-month mortality (P=0.001) and poor outcomes (P=0.001) statistically significantly. The area under curve of tau was similar to that of the National Institutes of Health Stroke Scale score for 3-month mortality (P=0.715) and poor outcomes (P=0.315). In a combined logistic-regression model, tau statistically significantly improved the area under curve of the National Institutes of Health Stroke Scale score for the prediction of 3-month poor outcome (P=0.039), but not for the prediction of 3-month mortality (P=0.106). CONCLUSIONS Serum tau concentration represents a novel biomarker for predicting mortality and poor outcomes at 3 months in patients with intracerebral hemorrhage.

Abstract
Fruit ripening is a complex phenomenon that makes berries attractive and also determines their nutritional value. Autumn olive ( Elaeagnus umbellata Thunb.) fruit is a rich source of many human health-related nutrients. The changes in pericarp color are initiated at early developmental stages, coinciding with the fast increase in fruit size. Fruit quality traits with special emphasis on soluble sugars, organic acids, lycopene, and total protein contents were assayed during the fruit ripening. In the fully ripe fruit, glucose and fructose were the principal sugars, malic acid was the most abundant organic acid, and lycopene concentration was extremely high. A proteomic analysis was used to identify up-accumulated proteins induced by the ripening. Among 63 up-accumulated protein spots, 43 were successfully identified by MALDI-TOF/TOF-MS. All 43 proteins were novel for autumn olive, and 8 were first reported in the fruit. Twenty-one proteins of known function were involved in sugar metabolism, citric acid cycle, isoprenoid metabolism, fatty acid synthesis, and protein hydrolysis. The possible roles of these 21 accumulated proteins in autumn olive fruit quality are discussed.

Abstract
Oxidative stress caused by amyloid β-peptide (Aβ) may play an important role in the pathogenesis of Alzheimer disease (AD). Aβ is known to be directly responsible for the production of reactive oxygen species (ROS) and induction of apoptosis. Tanshinone IIA (Tan IIA) is extracted from a traditional herbal medicine Salvia miltiorrhiza BUNGE, which has been shown to protect against oxidative stress and cell death. In this study, we investigated the neuroprotective effect of Tan IIA against Aβ₂₅₋₃₅-induced cell death in cultured cortical neurons. Exposure of cortical neurons to 30μM Aβ₂₅₋₃₅ caused a significant viability loss, cell apoptosis and decreased activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) as well as increased levels of malondialdehyde (MDA) production. In parallel, Aβ₂₅₋₃₅ significant increased the intracellular ROS elevation and decreased mitochondrial membrane potential (MMP). However, pretreatment of the cells with Tan IIA prior to Aβ₂₅₋₃₅ exposure suppressed these Aβ₂₅₋₃₅-induced cellular events noticeably. In addition, Tan IIA reduced the Aβ₂₅₋₃₅-induced increase of caspase-3 activity, and reduced cytochrome c translocation into the cytosol from mitochondria. Furthermore, Tan IIA also ameliorated the Aβ₂₅₋₃₅-induced Bcl-2/Bax ratio reduction in cortical neurons. Taken together, these data indicate that Tan IIA protected cultured cortical neurons against Aβ₂₅₋₃₅-induced neurotoxicity through its antioxidative potential. Our results strongly suggest that Tan IIA may be effective in treating AD associated with oxidative stress.

Abstract
OBJECTIVE To establish a nerve cell injury model by incubating primary rat cortical neurons in the presence of hydrogen peroxide (H2O2) to study the effect of emodin on apoptosis of nerve cells. METHODS Cortical neurons were incubated with H2O2 and emodin. The cell viability was measured by MTT and cell injury was evaluated by lactate dehydrogenate (LDH). Flow cytometry was used to evaluate the intracellular level of reactive oxygen species (ROS). The morphology of cortical cells were observed by inverted microscope and Hoechst 33258 staining. The expression of Bcl-2 and Bax were determined by western blot. RESULTS The 150 micromol/L H2O2 significantly decreased the viability of cortical cells and increased the level of intracellular ROS compared to control. Hoechest 33258 fluorescent staining showed brightness nucleosomes in apoptosis cells. The injury state was ameliorated by pretreatment of emodin. Moreover,as detected by Western blot analysis, H2O2 down-regulated the expression of Bcl-2 and up-regulation the expression of Bax compared to control. The state could be reversed by pretreatment of emodin. CONCLUSION Emodin can resist the adverse effects of H2O2 on increasing apoptotic rates, and it has the protective function towards nerve cells.

Abstract
Accumulation of beta-amyloid protein (Abeta) in the brain plays an important role in the pathogenesis of Alzheimer's disease (AD). In this study, the neuroprotective effect of emodin extracted from the traditional Chinese medicinal herb Polygonum cuspidatum Sieb. et Zucc against Abeta(25-35)-induced cell death in cultured cortical neurons was investigated. We found that pre-treatment with emodin prevented the cultured cortical neurons from beta-amyloid-induced toxicity. The preventive effect of emodin was blocked by pre-treatment with a phosphatidylinositol-3-kinase (PI3K) pathway inhibitor LY294002 or an estrogen receptor (ER) specific antagonist ICI182780, but not by pre-treatment with an extracellular signal-related kinases (ERK) inhibitor U0126. Furthermore, we found that emodin exposure induced the activation of the Akt serine/threonine kinase and increased the level of Bcl-2 expression. Moreover, the application of emodin for 24h was able to induce the activation of Abeta(25-35)-suppressed Akt and decrease the activation of the Jun-N-terminal kinases (JNK), but not of ERK. Interestingly, the up-regulation of Akt and Bcl-2 did not occur in the presence of LY294002 or ICI182780, suggesting that emodin-up-regulated Bcl-2 is mediated via the ER and PI3K/Akt pathway. Taken together, our results suggest that emodin is an effective neuroprotective drug and is a viable candidate for treating AD.

Abstract
Mitochondrial dysfunction is a hallmark of beta-amyloid (Abeta)-induced neuronal toxicity in Alzheimer's disease (AD), and is considered as an early event in AD pathology. Humanin (HN) and its derivative, [Gly14]-Humanin (HNG), are known for their ability to suppress neuronal death induced by AD-related insults in vitro and in vivo. In the present study, we investigated the neuroprotective effects of HNG on Abeta(25-35)-induced toxicity and its potential mechanisms in PC12 cells. Exposure of PC12 cells to 25 microM Abeta(25-35) caused significant viability loss and cell apoptosis. In addition, decreased mitochondrial membrane potential and increased cytochrome c releases from mitochondria were also observed after Abeta(25-35) exposure. All these effects induced by Abeta(25-35) were markedly reversed by HNG. Pretreatment with 100 nM HNG 6h prior to Abeta(25-35) exposure significantly elevated cell viability, reduced Abeta(25-35)-induced cell apoptosis, stabilized mitochondrial membrane potential, and blocked cytochrome c release from mitochondria. Furthermore, HNG also ameliorated the Abeta(25-35)-induced Bcl-2/Bax ratio reduction and decreased caspase-3 activity in PC12 cells. These results demonstrate that HNG could attenuate Abeta(25-35)-induced PC12 cell injury and apoptosis by preventing mitochondrial dysfunction. Furthermore, these data suggest that mitochondria are involved in the protective effect of HNG against Abeta(25-35).

Abstract
CONCLUSION The gentamicin-induced pathological alteration in the cochlear nucleus is not exclusively a secondary consequence of the damage in the cochlea. Instead, the toxic effect of gentamicin on the cochlear nucleus may occur simultaneously or even earlier than that on the cochlea. OBJECTIVES To investigate the pathological alteration of cochlear nucleus neurons in guinea pigs following systemic application of gentamicin. MATERIALS AND METHODS Guinea pigs were injected with gentamicin for 1 day, 3 days, 1 week, 2 weeks, and 3 weeks, respectively. In gentamicin-treated animals, the hearing function was evaluated by measuring the auditory brainstem response (ABR). The number and cross-sectional area of substance P-positive neurons in the cochlear nucleus were also measured. RESULTS The threshold of ABR and the number of substance P-positive neurons in the cochlear nucleus were significantly increased after 1 week and 3 days of injection of gentamicin, respectively. The cross-sectional area of substance P-positive neurons in the cochlear nucleus was significantly reduced after 1-day injection of gentamicin.

Abstract
The computing method for orthogonal Fourier-Mellin moments in a polar coordinate system is presented in detail. The image expressed in a Cartesian system has to be transformed into a polar coordinate system first when we calculate the orthogonal Fourier-Mellin moments of the image in a polar coordinate system, which will increase both computational complexity and error. To solve the problem, a new direct computing method for orthogonal Fourier-Mellin moments in a Cartesian coordinate system is proposed, which can avoid the image transformation between two coordinate systems and eliminate the rounding error in coordinate transformation and decrease the computational complexity.

Abstract
beta-Amyloid protein (Abeta), a major protein component of brain senile plaques in Alzheimer's disease, is known to be directly responsible for the production of reactive oxygen species (ROS) and induction of apoptosis. In this study, the protective effect of puerarin, an isoflavone purified from the radix of the Chinese herb Pueraria lobata, on Abeta-induced rat pheochromocytoma (PC12) cultures was investigated. Although exposure of PC12 cells to 50 microM Abeta25-35 caused significant viability loss and apoptotic rate increase, pretreatment of the cells with puerarin for 24h reduced the viability loss and apoptotic rate. Puerarin (1 microM) significantly inhibited Abeta25-35-induced apoptosis of PC12 cells. Preincubation of the cell with puerarin also restored the ROS and mitochondrial membrane potential levels that had been altered as a result of Abeta25-35 treatment. Puerarin was also found to increase the Bcl-2/Bax ratio and reduce caspase-3 activation. These results suggest that puerarin could attenuate Abeta25-35-induced PC12 cell injure and apoptosis and could also promote the survival of PC12 cells. Therefore, puerarin may act as an intracellular ROS scavenger, and its antioxidant properties may protect against Abeta25-35-induced cell injury.

Abstract
OBJECTIVE To establish a nerve cell injury model by incubating PC12 cell line in the presence of Abeta25-35 to study the effect of puerarin on apoptosis of nerve cells. METHODS PC12 cells were incubated with Abeta25-35 and puerarin. Cell viability was detected by MTT. The cellular morphology was observed with electron microscopy. FITC-labeled Annexin V and propidium iodide were adopted to evaluate the rate of cell apoptosis in different groups by means of flow cytometry. RESULTS Following incubation Abeta25-35, the cells were induced to undergo apoptosis. The viability of PC12 cells decreased in a time-dependent manner. Morphological evidences for apoptosis nuclear condensation were observed in PC12 cells. Cells incubated in the presence of Abeta25-35 showed increasing apoptotic rates, but cells treated with puerarin and Abeta25-35 revealed decreasing apoptotic rates, it demonstrated that puerarin had a significant protective action against Abeta25-35 evoked apoptosis. CONCLUSION Puerarin can resist the adverse effects of Abeta25-35 on increasing apoptotic rates, and it has the protective function towards nerve cells.

Abstract
OBJECTIVE To investigate the activation of nuclear factor kappaB (NF-KB) and the influence of puerarin on it after cerebral ischemia-reperfusion in rats. METHOD Cerebral ischemia-reperfusion injury was induced by 90 min of middle cerebral artery (MCA) occlusion and followed by 2, 6, 12, 24, 72 h reperfusion. Puerarin or saline was intra-peritoneally injected 1h before MCA occlusion and then the drugs were administered once every six hours. The infarct volume and brain edema were determined by TTC stain. Level of NF-kappaB P65 subunit was determined by immunohistochemistry and western blot. RESULT Immunohistochemistry revealed the translocation of NF-kappaB. A time course of NF-kappaB induction in brain showed that NF-kappaB P65 subunit obviously increased at 6 h, peaked at 24 h and then decreased by 72 h post-reperfusion. Puerarin decreased the level of NF-kappaB at 24, 72 h after reperfusion. There was a decrease trend in brain infarct volume between puerarin and control. CONCLUSION NF-kappaB is translocated and its level is increased after ischemia-reperfusion. Puerarin may attenuate the ischemia-reperfusion injury through inhibition of NF-kappaB activation.

Abstract
There is little information available on the mechanisms underlying the neuroprotective actions of the organoselenium compound ebselen. In this study, we sought to determine the relationship between alterations in the expression of Bcl-2 and Bax proteins and intracellular levels of calcium and the protective effects of ebselen with a concentration range of 0.01-20 microM against glutamate toxicity in cultured mouse cortical neurons. Pretreatment with ebselen at moderate doses (4-12 microM), but not at lower or higher doses, significantly improved glutamate-induced suppression of cell viability. Pretreatment with ebselen (8 microM) also prevented apoptotic alterations, completely reversed the suppression of Bcl-2 expression, and significantly inhibited Bax overexpression, but did not alter elevated intracellular concentrations of calcium induced by glutamate. Pre-, co-, and post-treatment with ebselen (8 microM) had similar potency in improving the decreased viability of glutamate-exposed cells. These results indicate that the neuroprotective effects of ebselen at low doses are associated with the regulation of Bcl-2 and Bax proteins but appear to be independent of glutamate-mediated elevation of intracellular calcium, suggesting that different mechanisms are involved in the actions of low and high dose regimens. Ebselen may be an effective agent used for early treatment of acute brain injuries.

Abstract
OBJECTIVE To investigate the protective effect of Mailuoning on the facial nerve demyelination of Hemifacial spasm and provide the data for therapy of Hemifacial spasm. METHOD 24 New Zealand white rabbits were divided into control group, Saline group and Mailuoning group, on the latter two groups the models of Hemifacial spasm were made by the temporal superficial artery closely contacting the main trunk of facial nerve at stylomastoid foramen. From the 5th week, the Saline and Mailuoning were injected intravenously into ear margin for 2 weeks on Saline and Mailuoning group respectively. At the 7th week, the MDA and SOD in serum were measured, mean while the microstructure and ultrastructure of facial nerve were observed on 3 animal groups. RESULT The MDA decreased obviously (P < 0.05) and SOD increased significantly (P < 0.01) in Mailuoning group comparing with that of Saline group, while the MDA and SOD showed insignificant changes of Mailuoning group and control group. The facial nerve severely demyelinated and axons retrogressively changed in Saline group but mild in Mailuoning group. CONCLUSION Mailuoning injection has a significant protective effect on the facial nerve demyelination of Hemifacial spasm and the very important applied value for therapy of Hemifacial spasm.

Abstract
OBJECTIVE To investigate the tumor-suppression effect of PA combined with GM-CSF, TNF-alpha and IL-4 on cord blood mononuclear cells (CBMC). METHODS The mononuclear cells were isolated from human umbilical cord blood and cultured with polyacttin A (PA), GM-CSF + TNF-alpha + IL-4 (GTI), and GTI + PA (GTIP) respectively. Six days later, surface antigen expression of the cultured cells, including CD1a and CD83, which were the specialized markers of dendritic cell (DC), were analyzed by immunohistochemistry technique. The CBMC were cultured with GTI for 24 h to enhance DC, then were added apoptotic/necrotic Hela/HepG2 tumor cells, and finally PA was co-cultured. The antitumor cytotoxicity of CBMC was measured by MTT assay. RESULTS After the culture, CD1a and CD83 positive cell rates of the PA group inreased significantly, reaching (19.63 +/- 3.61)%, (9.28 +/- 4.31) % respectively, much higher than that of the control, but lower than that of the GTI group. The killing rate to the tumor cells of CBMC cultured with GTIP increased remarkably, much higher than the control, GTI and PA groups. After tumor antigens were added to the CBMC of GTIP group (GTIP + Tc), the killing rate increased. CONCLUSION PA not only promotes the proliferation and maturation of cord blood derived DC, but also improves the tumor-suppression effect of CBMC cultured with GTI.

Abstract
OBJECTIVE To explore the arterial origin of the facial nerve and the site of the arteries joining it in cerebellopontine angle (CPA), in order to provide anatomical data for clinical application. METHODS The nutrient arteries were observed on 22 fresh adult head specimens fixed and perfused with formalin and gelatin under operation microscope. RESULTS Of all the nutrient arteries of facial nerve motor root,31 were derived from the artery loops in CPA space (50.82%) and 17 from the branch of anterior inferior cerebellar artery (27.88%). Eight of them originated from the labyrinthine artery (13.1%), 3 from posterior inferior cerebellar artery (4.92%) and 2 from basilar artery (3.28%) respectively. Forty-seven nutrient arteries (77.05%) entered the proximal 1/3 segment of facial nerve motor root. Thirty-six nutrient arteries of nervus intermedius raised from the artery loops in CPA space (73.47%), 7 from the branch of anterior inferior cerebellar artery (14.29%) and 6 from labyrinthine artery (12.24%) respectively. CONCLUSIONS The observation of the arterial origin of the facial nerve and the site of the arteries joining it in cerebellopontine angle provided an anatomic basis for the etiology of hemifacial spasm and the microsurgical operation in CPA.

Abstract
OBJECTIVE To detect the presence of endothelial injury in patients with severe acute respiratory syndrome (SARS) via enhanced levels of tissue-type plasminogen activator (t-PA) and soluble thrombomodulin (sTM). METHODS Case patients were from Xuanwu Hospital (Capital University of Medical Sciences, Beijing, China), and all of them met clinical criteria for SARS. Healthy controls were some of the hospital employees. Endothelial injury bio-markers tPA and sTM were detected by commercial ELISA-methods. RESULTS Classic plasma markers of endothelial injury, tPA and sTM significantly elevated in SARS patients in comparison to controls [t-PA: 1.48 +/- 0.16 nmol/L versus 0.25 +/- 0.03 nmol/L (P<0.0001), and sTM: 0.26 +/- 0.06 nmol/L versus 0.14 +/- 0.02 nmol/L (P<0.05)]. The only patient who died had extremely high levels of these endothelial injury markers (t-PA: 2.77 nmol/L and sTM: 1.01 nmol/L). The likelihood ratio analysis indicated the excellent discriminating power for SARS at the optimal cut-point of 0.49 nmol/L for tPA and 0.20 nmol/L for sTM, respectively. Significant numerical correlations were found among these endothelial injury markers in SARS patients. The numerical coefficient of correlation Pearson r between t-PA and sTM was 0.5867 (P<0.05). CONCLUSION Increased plasma concentrations of tPA and sTM in patients with SARS suggest the possibility of endothelial injury. SARS patients might need anticoagulant therapy or fibrinolytic therapy in order to reverse intraalveolar coagulation, microthrombi formation, alveolar and interstitial fibrin deposition. It may not only provide a useful treatment and prognostic index but also allow a further understanding of the pathological condition of the disease.

Abstract
AIM: To investigate the role of cyclin D1, p16 and retinoblastoma in cancerous process of gallbladder carcinomas and to assess the relation between cyclin D1, p16, Rb and the biological characteristics of gallbladder carcinoma.
METHODS: Forty-one gallbladder carcinoma, 7 gallbladder adenoma and 14 chronic cholecystitis specimens were immunohistochemically and histopathologically investigated for the relation of cyclin D1, p16 and Rb with Nevin staging and pathologic grading.
RESULTS: The expression rates of abnormal cyclin D1 in gallbladder carcinoma (68.3%)and gallbladder adenoma(57.1%) were significantly higher than those in chronic cholecystitis (7.1%) (P<0.05). No significant difference was found both among the pathological grades G1, G2 and G3 and among Nevin stagings S1-S2, S3 and S4-S5 of gallbladder carcinoma. The positive rates of p16 (48.8%) and Rb (58.5%) in gallbladder carcinoma were significantly lower compared to those in adenoma (100.0%) and cholecystitis (100.0%) (P<0.05). The positive rates of p16 and Rb in Nevin stagings S1-S2 (80.0% and 90.0%) and S3 (46.2% and 61.5%) gallbladder carcinomas were significantly higher than those in S4-S5 (33.3% and 38.8%) (P<0.05), and those in pathologic grades G1 (54.5% and 81.8%) and G2 (50.0% and 62.5%) gallbladder carcinoma were significantly higher than those in G3 (28.6% and 35.7%) (P<0.05). The protein expression of p16 and Rb had a negative-correlation in gallbladder carcinoma (r = -0.2993, P<0.05), and this negative-correlation was correlated with Nevin staging (P<0.05). Moreover, the protein expression of p16 and cyclin D1 had a negative-correlation in gallbladder carcinoma (r = -0.9417, P<0.05).
CONCLUSION: Cyclin D1 may play a role in the early stage of gallbladder carcinoma. Mutation of p16 and Rb genes might be correlated with progression of gallbladder carcinoma. Analysis of p16 and Rb can estimate the prognosis of gallbladder carcinoma. Expression of p16 and Rb may be correlated with Nevin staging and pathologic grading in gallbladder carcinoma.

Abstract
Excess aluminum (Al) exposure impairs neurocognitive function in humans and animals. Epidemiologic studies have shown a potential link between chronic Al exposure and Alzheimer's disease. In the present study, we sought to evaluate the protective effects of the herbal medicine Dipsacus asper extract against the cognitive impairment and overexpression of hippocampal beta-amyloid protein (Abeta) induced by chronic Al exposure in rats. Vitamin E (VE) was used as a positive control. Following exposure to 0.3% aluminum chloride (AlCl(3)) solution for 90 days in their drinking water, animals displayed a striking decrease (>80%) in step-through latency in the passive avoidance task and a significant increase (123%) in the number of Abeta immunoreactive cells in the hippocampus compared to controls. Al-exposed animals were then randomly assigned to receive vehicle, Dipsacus asper extract (4 g/kg), or VE (40 mg/kg) treatment up to 5 months. Both Dipsacus asper extract and VE significantly ameliorated animal's performance impairment in the passive avoidance task and suppressed the overexpression of hippocampal Abeta immunoreactivity. The effects of Dipsacus asper extract, but not VE, increased with time of treatment. The present results suggest that Dipsacus asper extract may possess therapeutic effects against Alzheimer's disease.
