Abstract
Objective: To explore the efficacy and safety of immunoneoadjuvant therapy with pembrolizumab combined with chemotherapy in locally advanced resectable hypopharyngeal squamous cell carcinoma patients. Methods: This study was a prospective, single arm, single center clinical study that was opened for enrollment in April 2021. Patients who met the inclusion criteria at the Cancer Hospital of the Chinese Academy of Medical Sciences were treated with neoadjuvant therapy of pembrolizumab combined with cisplatin and paclitaxel, and after treatments, received surgery and postoperative adjuvant therapy. The main endpoint of this study was postoperative pathological complete response (pCR), and other observations included adverse reactions and long-term prognoses of patients after neoadjuvant therapy. Results: By September 2023, a total of 23 patients who underwent neoadjuvant therapy and surgery were enrolled in the study and all patients were males aged 49-74 years. All patients were locally advanced stage, including 3 patients in stage Ⅲ and 20 patients in stage Ⅳ. There were 12 cases of primary lesions with posterior ring involvement accompanied by fixation of one vocal cord and 20 cases of regional lymph node metastases classified as N2. Eighteen cases received a two cycle regimen and 5 cases received a three cycle regimen for neoadjuvant therapy. The postoperative pCR rate was 26.1% (6/23), with no surgical delay caused by adverse drug reactions. The laryngeal preservation rate was 87.0% (20/23). Pharyngeal fistula was the main surgical complication, with an incidence of 21.7% (5/23). The median follow-up time was 15 months, and 3 patients experienced local recurrence. Conclusions: The immunoneoadjuvant therapy of pembrolizumab combined with chemotherapy has a high pCR rate in locally advanced resectable hypopharyngeal squamous cell carcinoma, with increased laryngeal preservation rate and no significant impact on surgical safety.

Abstract
OBJECTIVE To assess the effect of tumor cell lysate (TCL) with low high-mobility group B1 (HMGB1) content for enhancing immune responses of dendritic cells (DCs) against lung cancer. METHODS TCLs with low HMGB1 content (LH-TCL) and normal HMGB1 content (NH-TCL) were prepared using Lewis lung cancer (LLC) cells in which HMGB1 was inhibited with 30 nmol/L glycyrrhizic acid (GA) and using LLC cells without GA treatment, respectively. Cultured mouse DCs were exposed to different doses of NH-TCL and LH-TCL, using PBS as the control. Flow cytometry was used to detect the expressions of CD11b, CD11c and CD86 and apoptosis of the stimulated DCs, and IL-12 levels in the cell cultures were detected by ELISA. Mouse spleen cells were co-cultured with the stimulated DCs, and the activation of the spleen cells was assessed by detecting CD69 expression using flow cytometry; TNF-β production in the spleen cells was detected with ELISA. The spleen cells were then co-cultured with LLC cells at the effector: target ratios of 5:1, 10:1 and 20:1 to observe the tumor cell killing. In the animal experiment, C57/BL6 mouse models bearing subcutaneous LLC xenograft received multiple injections with the stimulated DCs, and the tumor growth was observed. RESULTS The content of HMGB1 in the TCL prepared using GA-treated LLC cells was significantly reduced (P < 0.01). Compared with NH-TCL, LH-TCL showed a stronger ability to reduce apoptosis (P < 0.001) and promote activation and IL- 12 production in the DCs. Compared with those with NH-TCL stimulation, the DCs stimulated with LH-TCL more effectively induced activation of splenic lymphocytes and enhanced their anti-tumor immunity (P < 0.05). In the cell co-cultures, the spleen lymphocytes activated by LH-TCL-stimulated DCs showed significantly enhanced LLC cell killing activity (P < 0.01). In the tumor-bearing mice, injections of LH-TCL-stimulated DCs effectively activated host anti-tumor immunity and inhibited the growth of the tumor xenografts (P < 0.05). CONCLUSION Stimulation of the DCs with LH-TCL enhances the anti-tumor immune activity of the DCs and improve the efficacy of DCbased immunotherapy for LLC in mice.

Abstract
Objective: To explore the mechanism of nerve growth factor (NGF) in the skeletal muscle fiber remodeling in ischemic limbs during therapeutic angiogenesis. Methods: Eighteen female mice with SPF grade, 6 weeks old and 25-30 g weighed were randomly allocated to sham-operated group (n=6), blank control group (n=6) and NGF gene transfection group (n=6). The left hindlimb ischemia models were established by ligating the femoral artery in blank control group and NGF gene transfection group. Seven days after the operation, mice in the three groups were separately injected with normal saline, empty plasmids, and NGF plasmids. Gastrocnemius of left hindlimbs was harvested after the blood perfusion assessment of the ischemic limb on the 21st postoperative day. The gastrocnemius muscle specimens were stained with HE, CD31 and proliferating cell nuclear antigen (PCNA) immunohistochemistry staining, the mRNA expressions of myosin heavy chain-Ⅰ(MHC-Ⅰ), MHC-Ⅱa and MHC-Ⅱb were measured by real-time PCR, and the protein level of NGF and peroxisome proliferator-activated receptors-β/δ (PPAR β/δ) were detected by Western blot. The expression of cytochrome C oxidase (COX), isocitrate dehydrogenase (IDH) and adenosine triphosphate (ATP) were examined by enzyme-linked immunosorbent assay (ELISA). Results: On the 21st day after operation, the blood perfusion of the ischemic limb in NGF gene transfection group was (195.70±9.99)PU, which was lower than that in sham-operated group (312.15±17.32)PU (P=0.001), while it was higher than that in blank control group (82.11±8.55)PU (P=0.001). The degree of muscle atrophy in the NGF gene transfection group was lower than that in the blank control group. The capillary density of NGF gene transfection group (0.34±0.05) was higher than that of sham-operated group (0.11±0.03) and blank control group (0.27±0.04) (P<0.05). The endothelial cell proliferation index in NGF gene transfection group (0.39±0.19) was significantly higher than that in sham-operated group (0.18±0.01) and blank control group (0.25±0.14) (P<0.05). The expression of NGF, PPAR β/δ, COX, IDH, ATP, and MHC-Ⅰ mRNA in NGF gene transfection group were significantly higher than those in sham-operated group and blank control group (P<0.05). Conclusions: NGF gene transfection can promote angiogenesis in the ischemic limbs of mice, increase the blood perfusion, and thus induce the remodeling of skeletal muscle fibers to type Ⅰ. This process may be related to NGF-induced PPAR β/δ expression and promote the cellular aerobic metabolism in skeletal muscle.

Abstract
Objective: To investigate the occurrence and development of aromatase inhibitors (AIs) related bone loss in Chinese patients with postmenopausal early-stage breast cancer. Methods: Patients with estrogen receptor (ER) and (or) progesterone receptor(PR) positive postmenopausal early-stage breast cancer who received Letrozole, Anastrozole, or Exemestane as adjuvant therapy were enrolled. Before treatment, baseline bone mineral density (BMD), bone metabolism markers were examined and a lifestyle questionnaire was completed; BMD was examined annually during the treatment; Outpatient visits were conducted to record recurrent and fatal events. Results: From November 2013 to August 2016, 131 patients with breast cancer eligible for enrollment were enrolled. A total of 65 patients had normal baseline bone mass, and 68 patients had reduced bone mass. Letrozole was taken in 69 patients, anastrozole in 52 patients, and exemestane in 10 patients. With a median follow-up of 43.7 months, 100 patients could be evaluated for changes in bone mineral density. Bone mineral density of femoral neck, total hip, and lumbar spine L1 to 4 decreased year by year, and the decrease was the most significant in the first year, which decreased by 2.3%, 2.4%, and 3.9% respectively. Ten new cases of osteoporosis occurred in two years, eight of them occurred in the lumbar spine, all of whom had reduced bone mass at baseline. Among the 131 patients who completed the lifestyle questionnaire, the proportions of daily calcium supplementation and vitamin D were 28.2% and 7.6%, respectively; more than half (52.7%) of them lacked regular exercise. Conclusion: BMD was declining steadily in patients treated with AIs, especially in the first year. Lumbar spine is the most common osteoporosis site, early prevention and health education should be strengthened.

Abstract
BACKGROUND AND PURPOSE The chemokine monocyte chemoattractant protein-1 (MCP-1) is involved in the pathogenesis of Alzheimer's disease (AD). This study aimed to investigate whether urinary MCP-1 can distinguish patients with AD, patients with amnestic mild cognitive impairment (aMCI) and cognitively normal (CN) subjects. METHODS A total of 754 participants, including 97 patients with AD, 50 patients with aMCI and 84 age- and sex-matched CN controls as well as a cohort of 523 CN subjects of different ages, were enrolled from five hospitals located in different areas of China. Urinary MCP-1 levels were determined using enzyme-linked immunosorbent assays. The correlations between urinary MCP-1 levels and cognition test scores or age were analysed. The optimal diagnostic sensitivity and specificity were determined using receiver operating characteristic curve analysis. RESULTS In the cohort of CN subjects of different ages, urinary MCP-1 levels increased with ageing and were correlated with age. The urinary MCP-1 levels were higher in females than in males. In the cohort composed of patients with AD, aMCI and age- and sex-matched CN controls, urinary MCP-1 levels were significantly higher in patients with AD and aMCI than in CN controls. There were no differences in urine MCP-1 levels between the AD group and the aMCI group. The urinary MCP-1 levels were correlated with the Mini-Mental State Examination scores and age, and were able to differentiate patients with AD and aMCI from CN subjects. CONCLUSIONS Urinary MCP-1 is a potential biomarker for the diagnosis of AD and aMCI.

Abstract
Objective: To investigate the clinical features, survival and prognostic factors of elder patients with diffuse large B-cell lymphoma (DLBCL). Methods: The clinical data of elder patients with diffuse large B-cell lymphoma enrolled in the Cancer Hospital of Chinese Academy of Medical Sciences from April 2006 to December 2012 were retrospectively collected. All the patients were divided into R-CHOP-like group and CHOP-like group according to the dosage regimen. And the differences in demographic characteristics, clinical features, survival time and prognostic factors were compared between these two groups. Results: A total of 158 patients were enrolled, of which 78 patients in the R-CHOP-like group and 80 patients in the CHOP-like group were eligible. There were no significant differences between two groups on age, gender, pathological staging, B symptoms, bulky mass, ECOG score, IPI score, pathological type, LDH level, β(2)-MG level, lymphocyte/monocyte ratio(LMR), neutrophils/lymphocyte ratio(NLR), platelet/lymphocyte ratio(PLR), Ki-67 index and bone marrow invasion. In the R-CHOP like group, the median progression-free survival (PFS) time was 10 months, and the median overall survival (OS) time was 30 months. The 1-year and 2-year PFS rates were 46.2% and 19.2%, respectively. The 1-, 2-, and 5-year OS rates were 79.5%, 59.0%, and 19.2%, respectively. In the CHOP-like group, the median PFS was 7 months, and the median OS was 15 months. The 1-year and 2-year PFS rates were 27.5% and 12.5% respectively. The 1-year, 2-year, and 5-year OS rates were 65.0%, 32.5% and 13.8%, respectively. The median PFS time and OS time in the R-CHOP group were significantly better than those in the CHOP group (P<0.05 for both). A stratified analysis showed that the PFS time and OS time were superior in the R-CHOP-like group compared to the CHOP-like group among patients older than 70 years (P<0.05 for both). In patients with stage Ⅲ-Ⅳ, the PFS time and OS time in the R-CHOP-like group were also superior to CHOP-like group (P<0.05 for both). Univariate Cox regression analysis showed that IPI score, LDH value, β(2)-MG value, ECOG score, LMR, and PLR had an significant effect on prognosis (P<0.05 for all). Multivariate Cox regression analysis showed that lymphocyte/monocyte ratio and platelet/lymphocyte ratio were independent prognostic factors for diffuse large B-cell lymphoma (P<0.05 for both). Conclusions: The R-CHOP-like chemotherapy regimen is superior to the CHOP-like regimen in the first-line treatment of patients with diffuse large B-cell lymphoma. ECOG score, LMR and PLR may be independent prognostic factors for diffuse large B-cell lymphoma. ECOG score, LMR and PLR are independent prognostic factors.

Abstract
OBJECTIVE We hypothesized that morphine has a depressing effect on early brain activity, assessed using quantitative aEEG/EEG parameter and depressed activity will be associated with brain volumes at term in extremely preterm infants. STUDY DESIGN 174 preterm infants were enrolled in 3 European tertiary NICUs (mean GA:26 ± 1wks) and monitored during the first 72 h after birth with continuous 2 channel aEEG. Six epochs of aEEG recordings were selected and minimum amplitude of aEEG (min aEEG), percentage of time amplitude <5 μV (% of time < 5 μV), spontaneous activity transients (SATrate) and interSAT interval (ISI) were calculated. For infants receiving morphine, the cumulative morphine dosage was calculated. In a subgroup of 58 infants, good quality MRI at term equivalent age (TEA) and the cumulative morphine dose until TEA were available. The effects of morphine administration and cumulative dose on aEEG/EEG measures and on brain volumes were investigated. RESULTS Morphine administration had a significant effect on all quantitative aEEG/EEG measures, causing depression of early brain activity [longer ISI (β 2.900), reduced SAT rate (β -1.386), decreased min aEEG (β -0.782), and increased % of time < 5 μV (β 14.802)] in all epochs. A significant effect of GA and postnatal age on aEEG/EEG measures was observed. Cumulative morphine dose until TEA had a significant negative effect on total brain volume (TBV) (β -8.066) and cerebellar volume (β -1.080). CONCLUSIONS Administration of sedative drugs should be considered when interpreting aEEG/EEG together with the negative dose dependent morphine impact on brain development.

Abstract
Deep-level sensors for detecting the local temperatures of inner organs and tissues of an animal are rarely reported. In this paper, we present a method to fabricate multifunctional micro-probes with standard cleanroom procedures, using a piece of stainless-steel foil as the substrate. On each of the as-fabricated micro-probes, arrays of thermocouples made of Pd-Cr thin-film stripes with reliable thermal sensing functions were built, together with Pd electrode openings for detecting electrical signals. The as-fabricated sword-shaped freestanding microprobes with length up to 30 mm showed excellent mechanical strength and elastic properties when they were inserted into the brain and muscle tissues of live rats, as well as suitable electrochemical properties and, therefore, are promising for potential biological applications.

Abstract
Electron beams (e-beams) have been applied as detecting probes and clean energy sources in many applications. In this work, we investigated several approaches for measurement and estimation of the range and distribution of local temperatures on a subject surface under irradiation of nano-microscale e-beams. We showed that a high-intensity e-beam with current density of 105-6 A/cm2 could result in vaporization of solid Si and Au materials in seconds, with a local surface temperature higher than 3000 K. With a lower beam intensity to 103-4 A/cm2, e-beams could introduce local surface temperature in the range of 1000-2000 K shortly, causing local melting in metallic nanowires and Cr, Pt, and Pd thin films, and phase transition in metallic Mg-B films. We demonstrated that thin film thermocouples on a freestanding Si3N4 window were capable of detecting peaked local surface temperatures up to 2000 K and stable, and temperatures in a lower range with a high precision. We discussed the distribution of surface temperatures under e-beams, thermal dissipation of thick substrate, and a small converting ratio from the high kinetic energy of e-beam to the surface heat. The results may offer some clues for novel applications of e-beams.

Abstract
Objective: The clinical features and prognosis of diffuse large B-cell lymphoma (DLBCL) were analyzed to optimize the treatment. Methods: We retrospectively collected the clinical data of patients with advanced-stage DLBCL from January 2006 to December 2012 in National Cancer Center/Cancer Hospital. The demographic characteristics, clinical stage, histological diagnosis, treatment and prognostic characteristics of these patients were analyzed. Results: A total of 370 patients with median age of 55 years old were recruited in the study. The male-to-female ratio was 1.3∶1. Among the 361 patients who underwent therapy, 280 cases received chemotherapy alone, 65 cases received chemoradiotherapy, and 16 cases received chemotherapy combined with autologous hematopoietic stem cell transplantation (AHSCT). The median follow-up period was 89 months, the 5-year overall survival (OS) rate of the entire cohort was 42.9%. The 5-year OS rate of chemotherapy alone, chemoradiotherapy and chemotherapy combined with AHSCT were 36.8%, 58.5%, 87.5%, respectively. The 5-year OS rate were significantly different between chemoradiotherapy and chemotherapy alone (P=0.001), and between chemotherapy combined with AHSCT and chemoradiotherapy (P=0.040). Univariate analysis showed that the age, Eastern Cooperative Oncology Group performance status (ECOG PS) score, Ann Arbor stage, B symptom, bulky disease, number of extranodal sites, Ki-67 index, lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), international prognostic index (IPI), therapeutic manner and chemotherapy combined with rituximab were significantly associated with the prognosis of advanced DLBCL patients (all P<0.05). Multivariate analysis demonstrated that the age >60 years, Ann Arbor stage IV, with B symptom, with bulky disease, ECOG PS≥1, Ki-67 index > 90%, CD5 expression, up-regulation of serum LDH and β2-MG, and chemotherapy without rituximab were related with the poor prognosis of patients with advanced-stage DLBCL (all P<0.05). Conclusions: Chemotherapy combined with rituximab can improve the outcome of patients with advanced-stage DLBCL. The age, stage, B symptom, bulky disease, ECOG PS score, Ki-67 index, CD5 expression, LDH, β2-MG and chemotherapy combined with rituximab are associated with the prognosis of these patients.

Kaplan-Meier method was used to compare the survival rates between groups, multivriate Cox proportional hazard regression analysis was performed to assess the independent prognostic significance of clinical and histopathological variables on events or OS. Results: A total of 361 patients were included in the study. Under a median follow-up of 89 months, the 5-year overall survival (OS) and progression-free survival (PFS) of the whole group were 42.9% and 31.3%, respectively. The 5-year OS rate and PFS rate were 48.2% and 35.1% in the low NLR group, which were 24.1% and 17.7% in the high NLR group, respectively. The 5-year OS rates and PFS rate were 45.4% and 33.2% in the low PLR group, which were 29.8% and 21.1% in the high PLR group (all P<0.05). Univariate analysis showed that NLR >5∶1, PLR >300∶1, age>60 year, ECOG PS>1 score, stage Ⅳ, B symptom, bulky disease, number of extranodal sites >1, Ki-67index >90%, LDH elevated and β2-MG elevated had significant influence on prognosis(all P<0.05). Multivariate analysis demonstrated that NLR, stage, B symptom, bulky disease, ECOG PS score, Ki-67 index and β2-MG were associated with poor prognosis in the advanced-stage DLBCL. Conclusions: NLR was simple and feasible biomarker for prognosis of advanced-stage DLBCL patients.

Abstract
Objective: To evaluate the clinical features and outcomes of HIV-negtive plasmablastic lymphoma (PBL). Methods: Nine patients with HIV-negtive PBL were diagnosed and treated between January 2006 and January 2016. The clinical and follow-up data were analyzed retrospectively. Results: The median age was 56 years (range 30-77 years) with a male-to-female ratio of 2∶1. Nobody had underlying diseases associated with immunosuppression. Primary extra nodal diseases were observed in 7 cases and only 1 patient had oral involvement. Two patients were in earlystage and 7 in advanced stage by the Ann Arbor stage system. Ki-67 index was 60%-90% in the 9 cases, and 80% or higher in 7 cases. Epstein-Barr virus-encoded RNA expression (EBER) was detected in 4 cases, and 2 of them were positive. Chemotherapy was documented in 9 patients, from which 8 received the cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP)-like regimens as the first-line chemotherapy and responses were observed in 5 (1 complete, 4 partial responses). Three elderly patients were treated with CHOP combined with thalidomide, and 2 of them achieved partial responses. One patient, failed three chemotherapy regimens, accepted thalidomide combined with etopside and achieved stable disease for 10 months. One patient with early stage had disease-free survival of 61.9 months after treatment. The other eight patients experienced recurrence or progression after the first-line chemotherapy, and 6 of them died of disease progression within 2 years after the diagnosis. Conclusion: The HIV-negative PBL patients in this study did not have an apparent association with immunosuppression. Primary extra nodal diseases were common, but only 1 patient had oral involvement. Most patients had advanced stage and poor prognosis. Effectiveness of thalidomide in the treatment of PBL deserves further investigation.

Abstract
OBJECTIVE To explore the clinical characteristics and prognosis of CD20-positive classical Hodgkin lymphoma (CHL). METHODS Data from CHL patients with CD20 immunohistochemical staining result who were treated in Cancer Hospital of Chinese Academy of Medical Sciences between September 2007 and March 2014 were reviewed. The relationship of CD20 expression in Reed-Sternberg(R-S)cells with CHL subtypes, clinical characteristics, and prognosis were analyzed. Fisher test was used to analyze the differences between groups and Kaplan-Meier for survival analysis. RESULTS A total of 263 patients were included in this study. Among the 263 patients, 74 (28.1%) were CD20-postitive. CD20-positive cases showed significantly higher proportions of Epstein-Barr virus (EBV) infection-related, mixed cellularity, and lymphocyte-rich CHL subtypes compared with CD20-negeative patients [52.8% (28/53) vs 19.0% (22/116), 37.9% (25/66) vs 31.6% (54/171), 22.7% (15/66) vs 3.5% (6/171), all P<0.05]. Univariate analysis identified EBV infection, age (≥ 40 years, especially ≥ 60 years), and Ⅲ-Ⅳ stage were correlated with reduced 3-year progression-free survival (PFS) and overall survival (OS) (PFS: 70.3 vs 87.7%, 79.2% vs 89.8%, 56.8% vs 91.5%, 70.4% vs 93.2%; OS: 81.0% vs 100%, 92.1% vs 99.4%, 75.4% vs 99.2%, 90.3% vs 100%; all P<0.05); and CD20-positive and not receiving local radiotherapy were associated with reduced PFS (79.7% vs 90.6%, 68.8% vs 90.6%, both P<0.05), not with OS (92.4% vs 98.3%, 94.0% vs 99.4%, both P>0.05). Patients positive in both CD20 expression and EBV-encoded small RNAs (EBER) showed low PFS. CONCLUSIONS CD20 expression in R-S cells in CHL may be closed related with EBV infection. EBV infection is associated with unfavorable prognosis. The effect of CD20-postitive on prognosis may be mediated by the prognostic effect of EBV infection.

Abstract
Tumor necrosis factor-α (TNF-α) is an important pro-apoptotic cytokine, which performs a broad range of immune and inflammatory functions in several vital processes. TNF-α-induced apoptosis has been confirmed, however, relatively little is known regarding the role of forkhead box class-O 1 (FOXO1) in mediating TNF-α-induced apoptosis in cervical cancer. In our study, we used the well-characterized cervical cancer cell line C-33A to investigate the role of FOXO1. The results showed that the antitumor agent TNF-α increased the expression level of FOXO1 (P < 0.05) and enhanced its transcriptional activity (P < 0.05). Furthermore, knockdown of FOXO1 repressed TNF-α-induced apoptosis and caspase-3, 8, and 9 expressions (P < 0.05). Collectively, these findings suggest that TNF-α upregulated the transcriptional factor FOXO1, leading to an increased expression of apoptotic gene, which leads to an increase in apoptosis.

Abstract
BACKGROUND AND AIMS Ulmus minor has been severely affected by Dutch elm disease (DED). The introduction into Europe of the exotic Ulmus pumila, highly tolerant to DED, has resulted in it widely replacing native U. minor populations. Morphological and genetic evidence of hybridization has been reported, and thus there is a need for assessment of interspecific gene flow patterns in natural populations. This work therefore aimed at studying pollen gene flow in a remnant U. minor stand surrounded by trees of both species scattered across an agricultural landscape. METHODS All trees from a small natural stand (350 in number) and the surrounding agricultural area within a 5-km radius (89) were genotyped at six microsatellite loci. Trees were morphologically characterized as U. minor, U. pumila or intermediate phenotypes, and morphological identification was compared with Bayesian clustering of genotypes. For paternity analysis, seeds were collected in two consecutive years from 20 and 28 mother trees. Maximum likelihood paternity assignment was used to elucidate intra- and interspecific gene flow patterns. KEY RESULTS Genetic structure analyses indicated the presence of two genetic clusters only partially matching the morphological identification. The paternity analysis results were consistent between the two consecutive years of sampling and showed high pollen immigration rates (∼0·80) and mean pollination distances (∼3 km), and a skewed distribution of reproductive success. Few intercluster pollinations and putative hybrid individuals were found. CONCLUSIONS Pollen gene flow is not impeded in the fragmented agricultural landscape investigated. High pollen immigration and extensive pollen dispersal distances are probably counteracting the potential loss of genetic variation caused by isolation. Some evidence was also found that U. minor and U. pumila can hybridize when in sympatry. Although hybridization might have beneficial effects on both species, remnant U. minor populations represent a valuable source of genetic diversity that needs to be preserved.

Abstract
Thyroid hormone insufficiency in adulthood causes a wide range of brain impairments, including altered synaptic proteins in the prefrontal cortex (PFC). The present study investigated whether adult-onset hypothyroidism altered the expression of soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complexes and synaptotagmin-1 (syt-1) in the PFC of rats. Sprague-Dawley rats were randomly divided into 4 groups: control, hypothyroid, and hypothyroid treated with T(4) [5 or 20 μg/100 g body weight (BW)]. Adult-onset hypothyroidism was induced in rats with the antithyroid drug 6-n-propyl-2-thiouracil (ip injection). PFC levels of synaptosomal-associated protein of 25 kDa (SNAP-25), syntaxin-1, vesicle-associated membrane protein 2 (VAMP-2) and syt-1 were determined by immunohistochemistry and western blot analyses. The results showed that syntaxin-1 and syt-1 were expressed at significantly lower levels in hypothyroid rats, VAMP-2 levels were not altered, and SNAP-25 levels were much higher compared to controls. A 2-week treatment with 5 μg T(4)/100 g BW partially normalized levels of SNARE complex and syt-1, and 20 μg T(4)/100 g BW restored these proteins closer to normal levels. Our findings indicate that dysregulation of SNARE complex and syt-1 in PFC of adult-onset hypothyroidism can be restored by T(4) treatment.

Abstract
Blood oxygen level dependent functional magnetic resonance imaging (fMRI) and the Stroop test were used to assess attentional cortex activation in patients with Alzheimer's disease, subcortical vascular dementia, and normal control subjects. Patients with Alzheimer's disease and subcortical vascular dementia demonstrated similar locations of cortical activation, including the bilateral middle and inferior frontal gyri, anterior cingulate and inferior parietal lobule in response to Stroop colour word stimuli. This activation was distinctly decreased in patients with dementia compared with normal control subjects. Different regions of the brain were activated in patients with Alzheimer's disease and subcortical vascular dementia compared with normal controls. fMRI is a useful tool for the study of dementia in humans and has some potential diagnostic value. Further studies with larger numbers of participants are required.

Abstract
The wing motions of a male and a female fire ant alate, which beat their wings at 108 and 96 Hz, respectively, were captured with a stereo imaging system at a high frame rate of 8,000 frames per second. By processing the high-speed image frames, the three-dimensional wingtip positions and the wing surface orientation angles were determined with a high phase resolution, i.e. 74 and 83 phases per period for the male and the female, respectively. A numerical reconstruction of the stereo wingbeat images demonstrated that the data collected described almost all the details of the wing surface motion, so that further computational fluid dynamic simulations are possible for fire ant alate flight.

Abstract
Three members of the tetraspanin/TM(4)SF superfamily were cloned from Chinese shrimp, Fenneropenaeus chinensis. The deduced amino acid sequences of the three proteins have typical motifs of the tetraspanin/TM(4)SF superfamily. Phylogenetic analysis of the proteins, together with the known tetraspanins of invertebrates and vertebrates, revealed that they belong to different tetraspanin subfamilies: CD9, CD63 and tetraspanin-3. The three cloned genes of CD9, CD63 and tetraspanin-3 showed apparently different tissue distributions. The CD9 gene (FcCD9) was specifically expressed in the hepatopancreas. While for the CD63 gene (FcCD63), the highest expression was detected in nerves, epidermis and heart, with low expression in haemocytes, ovary, gill, hepatopancreas and stomach and no expression in intestine, muscle and lymphoid organ. Compared with FcCD9 and FcCD63, the tetraspanin-3 gene (FcTetraspanin-3) was more broadly expressed and its highest expression was detected in the intestine. Its expression in nerves was lower than in the intestine, but was higher than in other tissues. Expression in haemocytes, ovary and muscle was much lower than in other tissues. The expression profiles of FcCD9, FcCD63 and FcTetraspanin-3 in different tissues, including haemocytes, lymphoid organ and hepatopancreas, were compared by real-time PCR when shrimp were challenged by live white spot syndrome virus (WSSV) and heat-inactivated WSSV. All three tetraspanins were markedly up-regulated in the live WSSV-challenged shrimp tissues. The data suggested that the three cloned members of TM(4)SF superfamily in Chinese shrimp may play a key role in the route of WSSV infection.

Abstract
Fabrication, characterization and application of periodical ferroelectric domains in ridges and Ti in-diffused ridge waveguides on X- and Y-cut Lithium Niobate (LN) are reported. The ridge waveguides of 3.5 microm height and 9 microm width were fabricated by inductively coupled plasma (ICP) etching followed by Ti in-diffusion into the ridges only. Appropriate electrodes on their side walls enabled domain inversion restricted to the ridge. The domain structure was investigated by selective chemical etching. Second harmonic generation in a 1.4 cm long ridge waveguide on an X-cut substrate was demonstrated at 1548 nm fundamental wavelength with an efficiency of 17% W(-1).

Abstract
We investigated the relationship between apolipoprotein E (APOE) promoters (G-219T, C-427T, A-491T) polymorphisms, and worsening CT results in early stage of traumatic brain injury (TBI) in a previously reported cohort of Chinese patients. Radiographic evidence of hemorrhage extension or delayed hemorrhage in acute stage (< 7 days after TBI) was judged by serial CT scanning compared to that on admission. APOE genotyping was performed by means of PCR-RFLP. Chi2 test and logistic regression analyses were done using SPSS software. Of 110 Chinese patients, 19 presented with deteriorated clinical condition in acute stage after hospitalization. Among these 19 patients, serial CT scanning revealed 3 cases with hemorrhage extension and 2 cases with delayed hemorrhage. Chi2 test showed no statistical differences in radiographic worsening/stabilization between the APOE epsilon4(+) and APOE epsilon4(-) groups (p = 0.170 > 0.05). Furthermore, no significant correlation between intracranial bleeding based on CT scanning with genotype or with haplotype frequencies for A-491T, C-427T, or G-219T was found by chi2 test (p > 0.05). In Chinese population, our data do not support the hypothesis that genetic variations within the APOE gene are associated with CT worsening in early stage of TBI.

Abstract
Monoclonal antibody P1H12 recognizes circulating endothelial cells and endothelia of all sizes of blood vessels. To identify the protein recognized by P1H12, we expressed a cDNA library in CHO cells and sequenced the cDNA from positive cells. The P1H12 sequence was identical, except at several bases, to that reported for melanoma cell surface antigen MUC18/CD146. Aggregation assays demonstrated that CD146 mediates Ca(++)-independent homotypic endothelial cell adhesion. P1H12 mAb abrogated interactions between human microvascular endothelial cells (HMVECs) but not between human umbilical vein endothelial cells (HUVECs). P1H12 mAb abrogated P1H12-positive (CHO(P1H12))-association with HMVECs or HUVECs. CD146 distribution is sparser on HUVECs than on HMVECs. These data imply that HMVECs and HUVECs express the CD146 binding partner but that CD146 is functional (or at sufficient density) only on HMVECs. HMVEC monolayers treated with soluble P1H12 mAb showed increased permeability to albumin, with accompanying changes in actin, paxillin, FAK, and caveolin distribution and changes in tyrosine phosphorylation of FAK. Stimulation with P1H12 mAb led to redistribution of NF-kappa B to the nucleus. P1H12 mAb bound to beads inhibited closure of wounded endothelial monolayers. CD146 thus joins VE-cadherin and PECAM-1 as a molecule that mediates homotypic endothelial cell adhesion. CD146 has both structural functions and signaling functions important for endothelial monolayer integrity.

Abstract
The one-stage curved osteotomy of the mandibular angle without resection of the masseter was used for 38 patients suffering from prominent mandibular angle from december 1996 to november 1997 at our department of plastic and cranio-maxillo-facial surgery. The preoperative strategy and surgical procedure are described. These 38 cases had a low rate of complications and usually good cosmetic results. Technical refinements that have improved the results are analyzed. At the present time the one-stage curved osteotomy of the mandibular angle is a simple and more reliable method for the surgical correction of the prominent mandibular angle, which is preferred by us to the other techniques: resection of the masseter alone or with straight cutting of the mandibular angle, simple straight cutting of the mandibular angle, multistaged osteotomy of the mandibular angle.

Abstract
Cytokines are small proteins that have an essential role in the immune and inflammatory responses. The repertoire of cytokines is becoming diverse and expanding. Here we report the identification and characterization of a novel cytokine designated as chemokine-like factor 1 (CKLF1). The full-length cDNA of CKLF1 is 530 bp long and a single open reading frame encoding 99 amino acid residues. CKLF1 bears no significant similarity to any other known cytokine in its amino acid sequence. Expression of CKLF1 can be partly inhibited by interleukin 10 in PHA-stimulated U937 cells. Recombinant CKLF1 is a potent chemoattractant for neutrophils, monocytes and lymphocytes; moreover, it can stimulate the proliferation of murine skeletal muscle cells. These results suggest that CKLF1 might have important roles in inflammation and in the regeneration of skeletal muscle.

Abstract
OBJECTIVE To investigate the pathological features of renal clear cell carcinoma (RCCC) in children and its relationship to the DNA content of cancer cells and DNA ploidy. METHODS The pathologic morphology of 4 cases of RCCC in children were observed. Using image analysis instruments the quantity of tumor cell DNA was measured. RESULTS The cytoplasm of the tumor cells were clear in all four cases. Papillary structures were present in these tumors, of which the papillary structure in two cases was over 50%, three cases had small calcified bodies with prominent bleeding and necrosis. Around tumor the glomerular and tubular of kidney always is normal the average DNA index was 1.31. They presented diploidy, high diploidy or subtetraploidy. CONCLUSIONS The specific features of most RCCC in children are clear cytoplasm, most contain papillary structures, calcified bodies, often with bleeding and necrosis. Around tumor the glomerular and tubular of kidney is always normal. The DNA contents of cancer cells present diploidy, high diploidy or subtetraploidy.

Abstract
Earthworm fibrinolytic enzyme component A, a protein which functions both as a direct fibrinolytic enzyme and a plasminogen activator, was purified from the earthworm Eisenia fetida. Diffraction-quality single crystals of the protein were grown by the hanging-drop vapour-diffusion technique with ammonium sulfate as a precipitant. The crystals belong to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 40.6, b = 127.5, c = 129.2 A and three molecules per asymmetric unit. The data set reached a resolution of 1.95 A.

Abstract
OBJECTIVE This paper presents a new method of osteotomy for the prominent mandibular angle (PMA). METHODS Two modifications have been made to the conventional procedures. The first is the one-stage curved osteotomy of the mandibular angle. The second is non-resection of the masseter muscle. The surgical procedure has been performed through an intraoral approach with a direct field of vision. RESULTS From December 1996 to December 1997, a total of thirty-eight patients suffering from PMA have been operated on by this method with satisfactory results. The follow-up is 3 to 12 months. CONCLUSION This method is a very simple and ideal procedure with much less complications for surgical treatment of PMA.
