Neoadjuvant chemotherapy combined with immunotherapy versus neoadjuvant chemoradiotherapy in patients with locally advanced esophageal squamous cell carcinoma. J Thorac Cardiovasc Surg 2024:S0022-5223(24)00008-4. [PMID: 38246339 DOI: 10.1016/j.jtcvs.2023.12.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 12/12/2023] [Accepted: 12/22/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND To date, few studies have compared effectiveness and survival rates of neoadjuvant chemotherapy combined with immunotherapy (NACI) and conventional neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced esophageal squamous cell carcinoma (ESCC). The present study was conducted to compare therapeutic response and survival between NACI and NCRT. METHODS The study cohort comprised patients with locally advanced ESCC treated with either NACI or NCRT followed by surgery between June 2018 and March 2021. The 2 groups were compared for treatment response, 3-year overall survival (OS), and disease-free survival (DFS). Survival curves were created using the Kaplan-Meier method, differences were compared using the log-rank test, and potential imbalances were corrected for using the inverse probability of treatment weighting (IPTW) method. RESULTS Among 202 patients with locally advanced ESCC, 81 received NACI and 121 received conventional NCRT. After IPTW adjustment, the R0 resection rate (85.2% vs 92.3%; P = .227) and the pathologic complete response (pCR) rate (27.5% vs 36.4%; P = .239) were comparable between the 2 groups. Nevertheless, patients who received NACI exhibited both a better 3-year OS rate (91.7% vs 79.8%; P = .032) and a better 3-year DFS rate (87.4% vs 72.8%; P = .039) compared with NCRT recipients. CONCLUSIONS NACI has R0 resection and pCR rates comparable to those of NCRT and seems to be correlated with better prognosis than NCRT. NACI followed by surgery may be an effective treatment strategy for locally advanced ESCC.

A model of hybrid speciation process drawn from three new poplar species originating from distant hybridization between sections. Mol Phylogenet Evol 2024; 190:107966. [PMID: 37981264 DOI: 10.1016/j.ympev.2023.107966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 11/11/2023] [Accepted: 11/16/2023] [Indexed: 11/21/2023]
Abstract
Although numerous studies have been conducted on hybrid speciation, our understanding of this process remains limited. Through an 18-year systematic investigation of all taxa of Populus on the Qinghai-Tibet Plateau, we discovered three new taxa with clear characteristics of sect. Leucoides. Further evidence was gathered from morphology, whole-genome bioinformatics, biogeography, and breeding to demonstrate synthetically that they all originated from distant hybridization between sect. Leucoides and sect. Tacamahaca. P. gonggaensis originated from the hybridization of P. lasiocarpa with P. cathayana, P. butuoensis from the hybridization of P. wilsonii with P. szechuanica, and P. dafengensis from the hybridization of P. lasiocarpa with P. szechuanica. Due to heterosis, the three hybrid taxa possess greater ecological adaptability than their ancestral species. We propose a hybrid speciation process model that incorporates orthogonal, reverse, and backcrossing events. This model can adequately explain some crucial evolutionary concerns, such as the nuclear-cytoplasmic conflict on phylogeny and the extinction of ancestral species within the distribution range of hybrid species.

Abstract
Objective: To investigate the multimodal imaging characteristics of acute macular retinopathy (AMR) and/or parafoveal acute middle maculopathy (PAMM) in patients with coronavirus disease 2019 (COVID-19). Methods: It was a cross-sectional study. Eight patients (15 eyes) diagnosed with AMN and/or PAMM, who presented for their initial visit at Kaifeng Eye Hospital between December 17 and December 31, 2022 and were also confirmed positive for COVID-19, were enrolled as the observation group. The patients were classified into four types based on swept-source optical coherence tomography (SS-OCT) findings. Fifteen healthy volunteers (15 eyes) without ocular or systemic diseases were recruited as the healthy control group, and one eye was randomly selected for analysis. All participants underwent detailed ophthalmic examinations, including best-corrected visual acuity (BCVA), slit-lamp biomicroscopy, fundus photography (FP), intraocular pressure measurement, fundus infrared imaging, OCT and OCT angiography (OCTA). The foveal avascular zone (FAZ) area of the macular center was measured. General information and multimodal imaging findings were collected and analyzed. The superficial capillary plexus vessel density (SCP-VD) and deep capillary plexus vessel density (DCP-VD) were measured in circular areas with diameters of 1.0 mm, >1.0 mm and ≤3.0 mm, and>3.0 mm and ≤6.0 mm centered on the foveal center, recorded as SCP-VD1.0, 3.0, 6.0 and DCP-VD1.0, 3.0, 6.0. Statistical analyses were performed using t-tests, Mann-Whitney U tests, and chi-square tests. Results: The observation group consisted of 6 males (11 eyes) and 2 females (4 eyes) with a mean age of (26.87±11.56) years. The healthy control group included 11 males (11 eyes) and 4 females (4 eyes) with a mean age of (28.75±12.30) years. There were no statistically significant differences in age and gender distribution between the two groups (all P>0.05). All patients in the observation group experienced high fever (≥39.0 ℃) and developed ocular symptoms during the febrile period or within 24 hours after fever resolution. Among all patients, there were 5 cases (7 eyes) of Type Ⅰ, 1 case (1 eye) of Type Ⅱ, 3 cases (4 eyes) of Type Ⅲ, and 2 cases (3 eyes) of Type Ⅳ. In Type Ⅲ and Ⅳ, 3 cases (4 eyes) exhibited weakly reflective cystic spaces in the outer plexiform or outer nuclear layers, and fundus photography revealed multiple gray or reddish-brown lesions in the macular region. One case (1 eye) showed retinal superficial hemorrhage. Cotton wool spots were observed in 2 cases (4 eyes). Fundus infrared imaging showed that Type Ⅰ manifested as weak reflectivity lesions in the parafoveal central zone, with the tip pointing towards the fovea. Type Ⅱ showed no apparent abnormalities in the macular region, while Type Ⅲ and Ⅳ displayed map-like weak reflective lesions spanning the foveal center. OCTA findings demonstrated that SCP-VD1.0 in the observation group was 6.93% (4.77%, 6.93%), significantly lower than the healthy control group's 10.66% (8.05%, 10.55%) (U=174.00, P=0.016). SCP-VD3.0 in the observation group was 37.14% (32.15%, 43.48%), also lower than the healthy control group's 43.06% (38.95%, 46.55%) (U=174.00, P=0.016). DCP-VD3.0 in the observation group was 48.20% (46.11%, 50.33%), lower than the healthy control group's 51.10% (50.04%, 53.02%) (U=188.00, P=0.009). DCP-VD6.0 in the observation group was 49.27% (47.26%, 51.67%), lower than the healthy control group's 52.43% (50.07%, 53.82%) (U=70.00, P=0.004). There were no significant differences in SCP-VD6.0 and DCP-VD1.0 between the two groups (both P>0.05). Conclusions: Acute macular retinopathy in patients with COVID-19 can involve all retinal layers and present as segmental hyper-reflectivity on SS-OCT. Fundus infrared imaging reveals weak reflectivity in the affected area, fundus photography shows multiple gray or reddish-brown lesions in the macular region, and OCTA demonstrates a decrease in SCP-VD and DCP-VD.

Abstract
Objective: To evaluate the efficacy of endoscopic transnasal surgery for sinonasal and skull base adenoid cystic carcinoma (ACC), and to analyze the prognostic factors. Methods: Data of 82 patients (43 females and 39 males, at a median age of 49 years old) with sinonasal and skull base ACC who were admitted to XuanWu Hospital, Capital Medical University between June 2007 and June 2021 were analyzed retrospectively. The patients were staged according to American Joint Committee on Cancer (AJCC) 8th edition. The disease overall survival(OS) and disease-free survival(DFS) rates were calculated by Kaplan-Meier analysis. Cox regression model was used for multivariate prognostic analysis. Results: There were 4 patients with stage Ⅱ, 14 patients with stage Ⅲ, and 64 patients with stage Ⅳ. The treatment strategies included purely endoscopic surgery (n=42), endoscopic surgery plus radiotherapy (n=32) and endoscopic surgery plus radiochemotherapy (n=8). Followed up for 8 to 177 months, the 5-year OS and DFS rates was 63.0% and 51.6%, respectively. The 10-year OS and DFS rates was 51.2% and 31.8%, respectively. The multivariate Cox regression analysis showed that late T stage and internal carotid artery (ICA) involvement were the independent prognostic factors for survival in sinonasal and skull base ACC (all P<0.05). The OS of patients who received surgery or surgery plus radiotherapy was significantly higher than that of patients who received surgery plus radiochemotherapy (all P<0.05). Conclusions: Endoscopic transonasal surgery or combing with radiotherapy is an effective procedure for the treatment of sinonasal and skull base ACC. Late T stage and ICA involvement indicate poor prognosis.

Abstract
A textile bandwidth-enhanced polarization-reconfigurable half-mode substrate-integrated cavity antenna was designed for wearable applications. A slot was cut out from the patch of a basic textile HMSIC antenna to excite two close resonances to form a wide -10 dB impedance band. The simulated axial ratio curve indicates the linear and circular polarization of the antenna radiation at different frequencies. Based on that, two sets of snap buttons were added at the radiation aperture to shift the -10 dB band. Therefore, a larger frequency range can be flexibly covered, and the polarization can be reconfigured at a fixed frequency by switching the state of snap buttons. According to the measured results on a fabricated prototype, the -10 dB impedance band of the proposed antenna can be reconfigured to cover 2.29~2.63 GHz (13.9% fractional bandwidth), and the circular/linear polarization radiation can be observed at 2.42 GHz with buttons OFF/ON. Additionally, simulations and measurements were carried out to validate the design and to study the effects of human body and bending conditions on the antenna performance.

Glutamine as a Potential Noninvasive Biomarker for Human Embryo Selection. Reprod Sci 2022; 29:1721-1729.

Abstract
To determine whether glutamine consumption is associated with embryo quality and aneuploidy, a retrospective study was conducted in an in vitro fertilization center. Spent embryo culture media from patients undergoing assisted reproduction treatment and preimplantation genetic testing (PGT) were obtained on day 3 of in vitro culture. Embryo quality was assessed for cell number and fragmentation rate. PGT for aneuploidy was performed using whole genome amplification and DNA sequencing. Glutamine levels in spent embryo culture media were analyzed by gas chromatography–mass spectrometry. The results demonstrated that glutamine was a primary contributor to the classification of the good-quality and poor-quality embryos based on the orthogonal partial least-squares discriminant analysis model. Glutamine consumption in the poor-quality embryos was significantly higher than that in the good-quality embryos (P < 0.05). A significant increase in glutamine consumption was observed from aneuploid embryos compared with that from euploid embryos (P < 0.01). The Pearson correlation coefficients between embryo quality and glutamine consumption, and between aneuploidy and glutamine consumption, were 0.430 and 0.757, respectively. The area under the ROC curve was 0.938 (95% CI: 0.902–0.975) for identifying aneuploidy. Animal experiments demonstrate that increased glutamine consumption may be a compensatory mechanism to mitigate oxidative stress. Our data suggest that glutamine consumption is associated with embryo quality and aneuploidy. Glutamine may serve as a molecular indicator for embryo assessment and aneuploidy testing.

Abstract
Objective: To investigate the correlation between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and central lymph node metastasis (CLNM) in patients with cN0 papillary thyroid microcarcinoma (PTMC). Methods: The clinicopathological data of PTMC patients confirmed by surgery and pathology in the 81st Military Hospital of People's Liberation Army from 2016 to 2019 were collected, and the relationship between preoperative NLR, PLR levels and postoperative PTMC CLNM were analyzed. Logistic regression analysis was used for multivariate analysis. Receiver operating characteristic (ROC) curve was used to determine the cutoff value of NLR and PLR. The interaction relative excess risk was used to analyze the relationship between NLR, PLR and CLNM. Results: Among 220 patients with cN0 stage PTMC, 92 were CLNM. The ROC curve showed that when the cutoff value of NLR was 2.5 and the cutoff value of PLR was 175, the highest Youden index was 0.318 and 0.264, respectively. NLR and PLR were both related to CLNM (P<0.05). The tumor long diameter, multifocality, NLR≥2.5 and PLR≥175 were independent impact factors of CLNM (P<0.05). The results of the interaction showed that the relative excess risk of the interaction was 5.531 (95%CI: 0.160, 10.901, P=0.016), the attribution ratio was 0.512 (95%CI: 0.230, 0.794, P=0.009), and the synergy index was 2.294 (95%CI: 1.492, 4.579, P=0.022), suggested that NLR and PLR had an interactive effect, and these two synergistically promoted CLNM. Conclusions: NLR and PLR are independent risk factors for cN0 stage PTMC CLNM. When NLR≥2.5 and PLR≥175, preventive central lymph node dissection should be routinely performed.

Abstract
Objectives This study aimed to investigate the functional effects of microRNA (miR)-214-5p on osteoblastic cells, which might provide a potential role of miR-214-5p in bone fracture healing. Methods Blood samples were obtained from patients with hand fracture or intra-articular calcaneal fracture and from healthy controls (HCs). Expression of miR-214-5p was monitored by qRT-PCR at day 7, 14 and 21 post-surgery. Mouse osteoblastic MC3T3-E1 cells were transfected with antisense oligonucleotides (ASO)-miR-214-5p, collagen type IV alpha 1 (COL4A1) vector or their controls; thereafter, cell viability, apoptotic rate, and the expression of collagen type I alpha 1 (COL1A1), type II collagen (COL-II), and type X collagen (COL-X) were determined. Luciferase reporter assay, qRT-PCR, and Western blot were performed to ascertain whether COL4A1 was a target of miR-214-5p. Results Plasma miR-214-5p was highly expressed in patients with bone fracture compared with HCs after fracture (p < 0.05 or p < 0.01). Inhibition of miR-214-5p increased the viability of MC3T3-E1 cells and the expressions of COL1A1 and COL-X, but decreased the apoptotic rate and COL-II expression (p < 0.05 or p < 0.01). COL4A1 was a target of miR-214-5p, and was negatively regulated by miR-214-5p (p < 0.05 or p < 0.01). Overexpression of COL4A1 showed a similar impact on cell viability, apoptotic rate, and COL1A1, COL-II, and COL-X expressions inhibiting miR-214-5p (p < 0.01). Conclusion Inhibition of miR-214-5p promotes cell survival and extracellular matrix (ECM) formation of osteoblastic MC3T3-E1 cells by targeting COL4A1. Cite this article: Q. S. Li, F. Y. Meng, Y. H.

Abstract
Objective: To evaluate the efficacy and safety of lenalidomide in a real-world clinical practice in Chinese patients with multiple myeloma (MM). Methods: It was a prospective, multi-center, observational study. A total of 165 consecutive patients with MM treated with lenalidomide-based regimens were enrolled in 12 hospitals from June 2013 to November 2015. Relevant information was recorded, such as baseline clinical data, cytogenetic abnormalities, treatment regimens, and duration of treatment, safety, and survival. Results: (1)There were 126 relapsed and refractory MM (RRMM) patients, 25 newly diagnosed patients and 19 maintenance patients. The evaluable RRMM patients accounted for 120 cases, among which 74 cases(61.7%) reached the partial response (PR) or above, and a very good partial response (VGPR) in 16 patients (13.3%), a complete response (CR) in 14 cases (11.7%), a strictly complete response (sCR) in 4 cases (3.3%). Thus, a VGPR or above in 34 patients accounted for 28.3%. (2)The median follow-up was 13 months, the median time to progression 12 months. The median survival after receiving lenalidomide was 19 months, and the median overall survival (OS) was 62 months. (3) The univariate analysis in 120 RRMM patients suggested that prognostic factors for significant improvement in PFS included normal karyotype, international staging system (ISS) Ⅰ-Ⅱ, t(4; 14) negative (detected by fluorescence in situ hybridization), non-bortezomib resistance and response to previous regimens. As to OS, non-bortezomib resistance, response to previous regimens and non-primary refractoriness were positive factors. Multivariate analysis showed that the response to previous regimens (PR or better) was an independent good prognostic factor for progress-free survival(PFS), non-bortezomib resistance and non-primary refractoriness for OS. (4) Grade 3 or 4 adverse events that occurred in more than 10% of all enrolled patients were neutropenia (12.7%), leukocytosis(11.5%) and thrombocytopenia (12.7%). Owing to intolerance of toxic side effects, 7 cases withdrew lenalidomide. Conclusions: No matter what combination, regimens containing lenalidomide are effective to RRMM patients with overall response rate 61.7%, a time to progression 12 months and an overall survival 62 months.The toxicity is quite tolerable and manageable. In addition, the response to previous treatment (reached PR or above) is the independent good prognostic factor for PFS, non-bortezomib resistance and non-primary refractoriness for OS. Clinical trail registration: Clinicaltrials.gov, NCT01947309.

Abstract
Amyloid precursor protein (APP) is a highly conserved integral membrane protein extensively expressed in various types of cells. Previously we found that overexpression of APP in patients with AML1/ETO-positive acute myeloid leukemia (AML) associated with a higher incidence of extramedullary infiltrationin and indicate a poor prognosis. In this study, we attempted to define the roles of APP in AML1/ETO-positive leukemia cells. Western blotting and qRT-PCR analysis showed that protein levels of APP are significantly higher in Kasumi-1, a t(8;21)/ AML1/ETO-positive M2-type AML cell line. Stable knockdown of APP by lentivirus-based RNA interference (RNAi) dramatically impaired colony-formation and migration ability of Kasumi-1 cells, whereas APP knockdown had very little effect on cell viability, apoptosis, cell cycle and differentiation. We further explored whether the pan-histone deacetylase inhibitor panobinostat could deplete the protein levels of APP in Kasumi-1 cells. Treatment with panobinostat caused depletion of APP in Kasumi-1 cells. These findings indicate that overexpression of APP is involved in promoting proliferation and migration of AML1/ETO-positive leukemia cells and can be inhibited by panobinostat, which provide an attractive prospect for treatment of AML1/ETO-positive AML.

Abstract
AIM: To investigate the clinical manifestations, imaging characteristics and treatment of focal nodular hyperplasia (FNH) of the liver.
METHODS: One hundred and seventy-six patients with FNH of the liver treated from January 2000 to January 2014 were retrospectively reviewed. The clinical and imaging features and treatment strategies were analyzed.
RESULTS: Among the 176 patients, 105 were male and 71 were female, with an average age of 36.2 ± 12.0 years (range, 4-69 years). Approximately 7.9% of cases had clinical symptoms, and 92.1% had no symptoms. The difference between computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of FNH had statistical significance. In this series, 87 patients underwent hepatectomy, 59 underwent laparoscopic hepatectomy, 12 received radiofrequency ablation, and 18 received DSA therapy.
CONCLUSION: FNH of the liver has no typical symptoms. The combination of various imaging examinations can improve diagnosis. Compared with traditional surgery, laparoscopic hepatectomy is becoming more and more popular because of its minor trauma.

Two rare 7,8-seco-lignans (1, 2), three new lignan glycosides (3, 4a, 4b), and 10 known lignans (5-14) were isolated from the fruit of Schisandra glaucescens Diels. The absolute configurations of 1 and 2 were determined by comparing their experimental and calculated electronic circular dichroism spectra. The molecular structures of the new compounds (3, 4a, and 4b), including their absolute configurations, were determined using various spectroscopic methods and hydrolysis reactions. The antioxidant activities of the isolated compounds were tested using 2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power assays. Compounds 4, 7, 8, 10, 11, and 12 exhibited antioxidant activities of varying potential in both assays. Of these compounds, 7 showed the strongest 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity, with IC50 values of 15.7 (150 μM DPPH) and 34.6 μM (300 μM DPPH), respectively, and 4, 12, and 7 displayed higher total antioxidant activities than Trolox in the ferric reducing antioxidant power assay. The neuroprotective effects of these compounds against Aβ25-35-induced cell death in SH-SY5Y cells were also investigated. Compounds 1, 2, 6, 7, 8, 11, and 12 exhibited statistically significant neuroprotective effects against Aβ25-35-induced SH-SY5Y cell death compared with the group treated only with Aβ25-35.

Abstract
The aim of this study was to evaluate differences in the effects of Ephedra sinica Stapf and Fructus Schisandrae Chinensis on angiogenesis in the treatment of bleomycin-induced rat idiopathic pulmonary fibrosis. The rat models were created using bleomycin. The animals were divided into six groups: model, control, Ephedra alone, Schisandrae alone, combination of Ephedra and Schisandrae, and hydrocortisone alone. The treatments were administered for 28 days. After 7 and 28 days, the rats were sacrificed for pathological morphology examination, microvascular density determination, and angiogenesis-related cytokine examination. The Ephedra and hydrocortisone groups demonstrated significantly reduced alveolitis and pulmonary fibrosis grades compared with the model group (P < 0.05). The number of blood vessels in the Ephedra group was higher than that in the Schisandrae and combination therapy groups. At 7 days, the expression level of endothelin (ET)-1 in the model group was significantly higher than that in the normal group (P < 0.01). The level of 6-keto-prostaglandin F1α (6-keto-PGF1α) in the treatment group increased, and there were significant differences between the Ephedra group and the combination therapy and normal groups (P < 0.05). Ephedra inhibited the increase in the lung coefficient. The combination therapy prevented pulmonary artery injury and angiogenesis of the arteries by reducing the level of ET-1 and promoting the level of 6-keto-PGF1α in the blood. Ephedra and Schisandrae prevented alveolitis and the development of pulmonary fibrosis.

Abstract
BACKGROUND Postherpetic neuralgia (PHN) is a common type of neuropathic pain occurring after resolution of herpes zoster rash. Although gabapentin is a widely used treatment, some disagreements exist about its efficacy and safety. Meta-analysis was performed to better evaluate the efficacy and safety of gabapentin for management of PHN. METHODS Randomized, double-blind, placebo-controlled trials of gabapentin to treat PHN were identified by searching MEDLINE, EMBASE, and CENTRAL databases. Searches were restricted to studies published in English. RESULTS Seven trials involving a total of 2039 participants were identified. Pooled analysis showed that gabapentin reduced PHN-related pain significantly more than placebo (mean difference, MD=-0.89, 95% CI -1.58 to -0.18, P<0.001). Gabapentin reduced pain below baseline by at least 50% in significantly more patients than did placebo (RR=1.59, 95% CI 1.35 to 1.88, P<0.001). Gabapentin was significantly more likely than placebo to lead patients to rate their global impression of change as "much improved" or "very much improved" (RR=1.82, 95% CI 1.41 to 2.35, P=0.003). Gabapentin also improved sleep quality significantly more than did placebo (MD=-0.62, 95% CI -0.67 to -0.57, P<0.001). On the other hand, patients given gabapentin were significantly more likely to experience dizziness, somnolence, peripheral edema, ataxia or gait disturbance and diarrhea. Subgroup analysis on formulation of gabapentin showed that gabapentin enacarbil had similar efficacy of pain relief with other formulations while it may be superior to others in term of compliance and safety. CONCLUSION This meta-analysis indicates that gabapentin is an effective and well-tolerated treatment for patients with PHN.

Abstract
The biological function of selenium (Se) is mainly elicited through Se-containing proteins. Selenoprotein W (SelW), one member of the selenoprotein family, is essential for the normal function of the skeletal muscle system. To investigate the possible relationship of Se in the process of differentiation in chicken myoblasts and the expression of SelW, the cultured chicken embryonic myoblasts were incubated with sodium selenite at different concentrations for 72 h, and then the mRNA levels of SelW and myogenic regulatory factors (MRFs) in myoblasts were determined at 12, 24, 48, and 72 h, respectively. Furthermore, the correlation between SelW mRNA expression and MRF mRNA expression was assessed. The results showed that the sodium selenite medium enhanced the mRNA expression of SelW, Myf-5, MRF4, and myogenin in chicken myoblasts. The mRNA expression levels of MRFs were significantly correlated with those of SelW at 24, 48, and 72 h. These data demonstrate that Se is involved in the differentiation of chicken embryonic myoblasts, and SelW showed correlation with MRFs.

Abstract
Two new tetrahydrofuran lignans, schiglaucin A and B (1-2), together with eight known analogues (3-10), were isolated from the stems of Schisandra glaucescens Diels. Their structures were elucidated on the basis of spectroscopic techniques (HRESIMS, UV, IR, NMR, and CD experiments). All of the compounds were tested for their neuroprotective activities against H₂O₂- and CoCl₂-induced cell injuries in SH-SY5Y cells, respectively. Compounds 1-10 showed significant neuroprotective effects against H₂O₂-induced SH-SY5Y cell death, while compounds 1-5 and 8-10 exhibited significant neuroprotective effects against CoCl₂-induced SH-SY5Y cell injury.

Abstract
BACKGROUND The determining risk factors for patients with squamous cell carcinoma of the hard palate are not well verified. METHODS Medical records from our facility of all patients with squamous cell carcinoma of the hard palate receiving curative surgery between March 2003 and May 2009 were reviewed. RESULTS Seventy-eight patients were enrolled in the study. The 5 year disease-free and overall survival rates were 49.8 and 49.7%, respectively. The 5 year disease-free and overall survival rates were statistically different between positive/close margins and negative margins (24.6% vs. 65.4%, P = 0.02; 20.1% vs. 63.1%, P = 0.001, respectively), with and without soft palate invasion (38.8% vs. 68.9%, P = 0.02; 27.4% vs. 77.5%, P = 0.001, respectively), and soft palate invasion patients with and without perineural invasion (10.4% vs. 52.8%, P = 0.02; 0% vs. 38.1%, P = 0.008, respectively). The rate of positive nodal metastasis for T3 and T4 tumors was 44%. For the tumor with soft palate invasion, the rate of positive nodal metastasis was 29%. After multivariate analyses, soft palate invasion and positive/close margins were the determining risk factors for disease-free and overall survival. CONCLUSIONS Soft palate invasion and positive/close margins were the determining risk factors for disease-free and overall survival in patients with squamous cell carcinoma of the hard palate. Elective neck dissection is suggested for advanced primary tumors (T3 or T4) or tumors with soft palate invasion.

Abstract
It is suggested that activation and differentiation of T-helper cells are required for peri-operative anti-tumor and anti-infection immunity. The present study aimed to evaluate whether propofol stimulates the activation and differentiation of these cells in patients undergoing pulmonary lobectomy for non-small-cell lung cancer. Thirty patients were randomly allocated to receive propofol or isoflurane throughout surgery. The CD4(+)CD28(+) percentage (p < 0.0001) and the ratio of interferon-gamma:interleukin-4 (p = 0.001) all increased with propofol but showed no change with isoflurane. In contrast, cortisol increased with isoflurane (p < 0.0001) but not with propofol over time (p = 0.06). We conclude that propofol promotes activation and differentiation of peripheral T-helper cells.

Arsenic trioxide induces the apoptosis in bone marrow mesenchymal stem cells by intracellular calcium signal and caspase-3 pathways. Toxicol Lett 2010; 193:173-8.

Abstract
It was previously reported that excessive arsenic trioxide would produce cardiovascular toxicity. Bone marrow mesenchymal stem cells (BMSCs) have been shown to play a supporting role in cardiovascular functions. The increasing apoptosis of BMSCs commonly would promote the development of cardiovascular diseases. Thus we hypothesize that arsenic trioxide caused apoptosis in BMSCs, which provided a better understanding of arsenic toxicity in hearts. The present study was designed to investigate the proapoptotic effects of arsenic trioxide on BMSCs and explore the mechanism underlying arsenic trioxide-induced BMSCs apoptosis. We demonstrate that arsenic trioxide significantly inhibited survival ratios of BMSCs in a concentration-dependent and time-dependent manner. The Annexin V/PI staining and terminal deoxynucleotidyl transferasemediated dUTP nick-end labelling (TUNEL) assay also showed that arsenic trioxide markedly induced the apoptosis of BMSCs. The caspase-3 activity was obviously enhanced in the presence of arsenic trioxide in a concentration-dependent manner in BMSCs. Additionally, arsenic trioxide caused the increase of intracellular free calcium ([Ca(2+)](i)) in rat BMSCs. BAPTA pretreatment may attenuate the apoptosis of BMSCs induced by arsenic trioxide. Taken together, arsenic trioxide could inhibit the proliferation and induce the apoptosis of BMSCs by modulating intracellular [Ca(2+)](i), and activating the caspase-3 activity.

Abstract
A complete surface reconstruction takes place after a local connection between two crossed tubes is established, leading to the creation of an extended X-shaped junction constituted by topological defects with smooth negative curvature. Molecular-dynamics simulations show that the surface reconstructions occur through (1) generalized Stone-Wales transformation and (2) the movement of sp and sp3 atoms and their transformation to sp2 atoms by bond rearrangement. Based on both the principle of energy minimization and a generalized Euler's rule, it is demonstrated that the most stable structure for X junctions contains only 12 heptagons. The annealing temperature influences the topological structure and stability of junctions.

Abstract
The transendothelial movement of solutes is a dynamic process controlled by a complex interaction between the cytoskeleton and adhesion proteins. The aim of this study was to examine whether protein tyrosine phosphorylation is involved in the regulation of endothelial barrier function. The apparent permeability coefficient of albumin (Pa) was measured in isolated and perfused coronary venules. Tyrosine phosphatase inhibitors, including phenylarsine oxide and sodium orthovanadate, dose and time dependently increased basal Pa. Western blot analysis of cultured coronary venular endothelial cells revealed that inhibition of tyrosine phosphatase induced an increase in phosphotyrosine content in a number of proteins, including bands at 65-70 and 120-130 kDa, which were identified as paxillin and focal adhesion kinase (pp125FAK), respectively. The time course and dose responsiveness of protein tyrosine phosphorylation were tightly correlated with those of increases in Pa. Furthermore, stimulation of endothelial cells with histamine or phorbol myristate acetate (PMA) enhanced tyrosine phosphorylation of paxillin and pp125FAK, which was blocked by the tyrosine kinase inhibitor damnacanthal. Correspondingly, the increases in venular permeability elicited by histamine and PMA were abolished in damnacanthal-treated venules. Taken together, the data suggest a possible involvement of protein tyrosine phosphorylation in the control of endothelial barrier function. Paxillin and its associated focal adhesion proteins may play a specific role in agonist-induced hyperpermeability responses in the endothelium of exchange vessels.

Abstract
We conducted an evaluation of the usefulness of antiemetics (5-Hydroxy-tryptamine 3 receptor antagonism, 5HT3RA) combined with diazepam for delayed nausea and vomiting due to anticancer agents in 17 patients with various malignancies (such as lung Ca, breast Ca, esophagus Ca, gastric Ca, colon Ca, and non Hodgkin's disease) for whom chemotherapy was performed with different regimens in the Dept. of Oncologic Chemotherapy, People's Hospital, Beijing Medical University. Antiemetics (5HT3RA) combined with diazepam were given only to cases that had symptoms of nausea and vomiting induced by anticancer agents in the 1st course and invalidity with antiemetics (5HT3RA) alone in this study. Antiemetic (5HT3RA) agents + Dexamethasone were dosed before chemotherapy and also diazepam 5 mg orally after 24 hours (namely, when nausea was observed). Nausea was reduced and vomiting decreased after the antiemetic treatment with 5HT3RA + Dexamethasone and diazepam. These results indicated that 5HT3RA and diazepam combination therapies were more effective than 5HT3 RA + Dexamethasone alone for delayed nausea and vomiting. Further, the antiemetics had characters that a short adminiter time, few times and a take not over dose. The only side effect related to this antiemetic therapy was light somnolence. Antiemetics combined with diazepam might be a useful therapy against delayed nausea and vomiting induced by anticancer agents.

Abstract
A close or even causal relation between myocardial adenosine and bradyarrhythmias during acute myocardial hypoxia was testified in guinea pig, rabbit and dog mainly by using specific competitive antagonist and synchronous quantitative analysis of 3 variables: intensity of myocardial hypoxia, degree of endogenous adenosine increment and severity of bradyarrhythmias. Results disclosed: A) striking resemblance of the bradyarrhythmias with hypoxic origin to those caused by exogenous adenosine, B) same locality of A-V conduction block induced by both myocardial hypoxia and exogenous adenosine, C) precise parallelism among the above-listed 3 variables with very high correlativity (r = 0.99, P < 0.01), D) frequent accompaniment of reversal of hypoxic bradyarrhythmias through resupply of 21% O2 with normalization of preexisted increase in myocardial adenosine, E) satisfactory blockade of hypoxic bradyarrhythmias by adenosine's specific antagonist--aminophylline and their augmentation by adenosine's uptake inhibitor--dipyridamole, F) close similarity of the characteristic curve representing relation among the above 3 variables to that among intensity of myocardial hypoxia, degree of endogenous adenosine increment and amount of coronary blood flow in which adenosine's role as a mediator has been well documented and G) reproducible persistence of bradyarrhythmias during myocardial hypoxia irrespective of preliminary vagotomy and atropinization, denoting independence of the occurrence of such dysarrhythmias upon vagal drive, suggestive of a mechanism other than vagotonia. We advocated that hypoxia-induced bradyarrhythmias was caused by increment in endogenous adenosine.

Abstract
Cell cycle phases of bone marrow cells from 8 patients with iron deficiency anemia (IDA), 8 aplastic anemia (AA), 30 myelodysplastic syndrome (MDS), 41 acute leukemia (AL) before treatment, 8 acute leukemia in relapse, 17 acute leukemia in complete remission (CR), 12 chronic myelogenous leukemia (CML) and 4 chronic lymphocytic leukemia (CLL) were analysed with flow cytometry. The proportions of phases of S. G2 M in patients with IDA, refractory anemia, and refractory anemia with ring sideroblast were similar to these in normal controls (P > 0.05). However, they were significantly lower in patients with AA, refractory anemia with excess of blast (RAEB) and transformed RAEB than those in normal controls (P < 0.01, respectively), and CML patients than in normal controls (P < 0.05). The S G2M% was apparently higher in patients with CML than that in CLL (P < 0.01). But, there was no difference between in ALL and ANLL (P > 0.05). It was higher in patients with AL in CR and in relapse than AL before treatment (both P < 0.01). It was still lower in the former than that in normal controls. (P < 0.05). The clinical significance of cell cycle status was also discussed in this paper.

Abstract
UNLABELLED Thirty-eight adults including 24 males and 14 females with acute nonlymphocytic leukemia were treated with DATV (Daunorubicin, Cytarabine, 6-thioguaninum, Vincristine) regimen from December 1987 to May 1991. The median age was 31 years old (range 13-54). The DATV regimen consisted of DNR 60 mg/day IV for 3 days; Ara-C 100 mg by continuous infusion every 12 hours for 7 days; 6-TG 150 mg PO for 7 days and VCR 2mg IV on day 1. RESULTS Complete remission (CR) was achieved in thirty-three of 38 patients after 1-2 courses (mean 1.3) with CR rates 86.8%. Five patients had no response to the regimen. Twenty-four of 33 patients who achieved CR are still in CR for 1-41 months with a median follow-up of 10 months.
