Abstract
Autophagy is implicated in the pathogenesis of psoriasis. We aimed to identify autophagy-related biomarkers in psoriasis via an integrated bioinformatics approach. We downloaded the gene expression profiles of GSE30999 dataset, and the "limma" package was applied to identify differentially expressed genes (DEGs). Then, differentially expressed autophagy-related genes (DEARGs) were identified via integrating autophagy-related genes with DEGs. CytoHubba plugin was used for the identification of hub genes and verified by the GSE41662 dataset. Subsequently, a series of bioinformatics analyses were employed, including protein-protein interaction network, functional enrichment, spearman correlation, receiver operating characteristic, and immune infiltration analyses. One hundred and one DEARGs were identified, and seven DEARGs were identified as hub genes and verified using the GSE41662 dataset. These validated genes had good diagnostic value in distinguishing psoriasis lesions. Immune infiltration analysis indicated that ATG5, SQSTM1, EGFR, MAPK8, MAPK3, MYC, and PIK3C3 were correlated with infiltration of immune cells. Seven DEARGs, namely ATG5, SQSTM1, EGFR, MAPK8, MAPK3, MYC, and PIK3C3, may be involved in the pathogenesis of psoriasis, which expanded the understanding of the development of psoriasis and provided important clinical significance for treatment of this disease.

Abstract
The aim of this study was to (1) assess the independent factors affecting patients with postoperative intestinal fistula from Crohn disease (CD) by analyzing preoperative clinical data, (2) establish a nomogram prediction model for this condition based on these factors, and (3) validate this model and evaluate its accuracy. In this retrospective multicenter case-control study, the clinical data of 240 patients with CD admitted for surgical treatment between September 2019 and September 2021 at 3 centers were collected. Patients were randomly divided into a training set (168 patients) and a validation set (72 patients). Univariate analysis was performed for relevant factors, and statistically significant factors were then analyzed using multivariate logistic regression to determine the independent influencing factors. A nomogram model for predicting postoperative intestinal fistula in patients with CD was constructed and the accuracy of the model was evaluated using calibration curves. Univariate analysis showed that disease behavior, abdominal abscess, intestinal perforation, neutrophil-to-lymphocyte ratio, systemic immunoinflammatory index, and prognostic nutrition index were factors affecting postoperative intestinal fistula in patients with CD. Multivariate logistic regression analysis showed that neutrophil-to-lymphocyte ratio, prognostic nutrition index, disease behavior, and Crohn disease activity index score were independent influencing factors. After assessing the validation set, the area under the curve was 0.899, indicating good predictive accuracy of the nomogram model. The prediction model developed in this study can effectively predict the risk of postoperative intestinal fistula.

Abstract
Lung cancer is one of the leading causes of cancer-related death. Most advanced lung adenocarcinoma (LUAD) patients have poor survival because of drug resistance and relapse. Neglecting intratumoral heterogeneity might be one of the reasons for treatment insensitivity, while single-cell RNA sequencing (scRNA-seq) technologies can provide transcriptome information at the single-cell level. Herein, we combined scRNA-seq and bulk RNA-seq data of LUAD and identified a novel cluster of malignant epithelial cells - KRT81+ malignant epithelial cells - associated with worse prognoses. Further analysis revealed that the hypoxia and EMT pathways of these cells were activated to predispose them to differentiate into metastatic lung adenocarcinoma cells. Finally, we also studied the role of these tumor cells in the immune microenvironment and their role in the classification and prognosis prediction of lung adenocarcinoma patients.

Abstract
Objective: To compare the efficacy of off-pump minimally invasive cardiac surgery (MICS) via a single left intercostal space incision with median sternotomy multi-vesselcoronary artery bypass grafting (CABG). Methods: Patients who were diagnosed with multi-artery coronary artery disease (CAD) in the Ward 10 of the Department of Cardiac Surgery, Beijing Anzhen Hospital Affiliated to Capital Medical University and underwent CABG from July 2019 to January 2022 were retrospectively collected. All the patients were divided into MICS group and conventional CABG group according to the surgical methods. The perioperative outcomes were compared between thetwo groups, including intraoperative blood loss, postoperative 24 h thoracic drainage volume, ventilation duration, length of stay (LOS) in intensive care unit (ICU) and total LOS in hospital. Intraoperative blood flow of graft vesselswas measured by transit-time flow measurement (TTFM) after vascular anastomosis, and mean flow (MF) and pulsatile index (PI) were compared between the two groups. Results: A total of 444 patients were in the final analysis, with 351 males and 93 females, and the mean age of (62.0±8.9) years. There were 179 patients in MICS group and 265 cases in conventional CABG group, respectively. There were no statistically significant differences in the preoperative profiles between the two groups (all P>0.05) except that younger age [(60.7±9.3) years vs (62.8±8.5) years, P=0.017] and lower proportion of female [10.1% (18/179) vs 28.3% (75/265), P<0.001] were detected in MICS group. Likewise, there was no significant difference in the number of graft vessels between MICS group (3.18±0.74) and conventional CABG group (3.28±0.86) (P=0.234). Compared with those in conventional CABG group, patients in MICS group showed longer operation duration [ (5.10±1.09) h vs (4.33±0.86) h], fewer intraoperative blood loss [500 (200, 700) ml vs 700 (600, 900) ml], fewer postoperative 24 h thoracic drainage volume [300 (200, 400) ml vs 400 (250, 500) ml], shorter postoperative ventilation duration [15.0 (12.0, 17.0) h vs 16.5 (12.5, 19.0) h, P<0.001], LOS in ICU [18.0 (15.0, 20.0) h vs 20.0 (16.0, 23.0) h, P<0.001] and total LOS in hospital [(12.6±2.7) d vs (14.5±3.9) d, P<0.001]. MI and PI of graft vessels were similar between the two groups (both P>0.05). Moreover, there were no significant differences in major perioperative complications (i.e., repeat thoracotomy, incision infection, stroke) and mortality between the two groups (all P>0.05). Conclusion: MICS is an alternative treatment for patients with multi-vessel CAD with better perioperative outcomes compared with conventional CABG.

Abstract
Objective Inter-hemispheric network dysconnectivity has been well-documented in patients with recurrent major depressive disorder (MDD). However, it has remained unclear how structural networks between bilateral hemispheres relate to inter-hemispheric functional dysconnectivity and depression severity in MDD. Our study attempted to investigate the alterations in corpus callosum macrostructural and microstructural as well as inter-hemispheric homotopic functional connectivity (FC) in patients with recurrent MDD and to determine how these alterations are related with depressive severity. Materials and Methods Resting-state functional MRI (fMRI), T1WI anatomical images and diffusion tensor MRI of the whole brain were performed in 140 MDD patients and 44 normal controls matched for age, sex, years of education. We analyzed the macrostructural and microstructural integrity as well as voxel-mirrored homotopic functional connectivity (VMHC) of corpus callosum (CC) and its five subregion. Two-sample t-test was used to investigate the differences between the two groups. Significant subregional metrics were correlated with depression severity by spearman's correlation analysis, respectively. Results Compared with control subjects, MDD patients had significantly attenuated inter-hemispheric homotopic FC in the bilateral medial prefrontal cortex, and impaired anterior CC microstructural integrity (each comparison had a corrected P < 0.05), whereas CC macrostructural measurements remained stable. In addition, disruption of anterior CC microstructural integrity correlated with a reduction in FC in the bilateral medial prefrontal cortex, which correlated with depression severity in MDD patients. Furthermore, disruption of anterior CC integrity exerted an indirect influence on depression severity in MDD patients through an impairment of inter-hemispheric homotopic FC. Conclusion These findings may help to advance our understanding of the neurobiological basis of depression by identifying region-specific interhemispheric dysconnectivity.

Abstract
PURPOSE Our and other's studies showed that administration of neuropeptide galanin may mitigate insulin resistance via promoting glucose transporter 4 (GLUT4) expression and translocation in rats. The objective of this study is to investigate whether galanin receptor 2 (GAL2-R) in brain mediates the ameliorative effect of galanin on insulin resistance in adipose tissues of type 2 diabetic rats. METHODS In this study galanin, GAL2-R agonist M1145 and GAL2-R antagonist M871 were respectively or cooperatively injected into intracerebroventricles of type 2 diabetic rats once a day for successive fifteen days. Then the plasma and fat tissues of rats were used to estimate the alterations of insulin resistance indexes. RESULTS The central administration of galanin enhanced 2-deoxy-[3H]-D-glucose, peroxisome proliferator-activated receptor γ and adiponectin levels, food intake and body weight, GLUT4 mRNA expression and GLUT4 concentration in plasma membranes, as well as homeostasis model assessment-insulin resistance index. Those effects of galanin may be blocked by M817, and imitated by M1145 except for food intake and body weight. CONCLUSION Those results suggest that central GAL2-R mediates the beneficial effects of galanin on insulin sensitivity in type 2 diabetic rats. GAL2-R agonist may be taken as a potential antidiabetic agent to treat insulin resistance and type 2 diabetes.

Abstract
ABSTRACT Enhancing the physical health of college students is the fundamental guarantee of cultivating high-quality talents. In order to understand the influencing factors of college students' physical health and carry out targeted intervention, this study aims to analyze the factors affecting college students' physical health. Through the construction of physical health evaluation index and its influencing factors evaluation index, the importance of different indicators is evaluated by using the analytic hierarchy process, and a questionnaire about college students' physical health and its influencing factors is designed. The results show that the factors affecting college students' physical health include students' own factors, school factors, and others. At the same time, the insufficient construction of public sports facilities and the lack of first-class sports venues and equipment are also the reasons for the decline of college students' physique. Therefore, we can intervene in the students' physical health from the aspects of raising the students' awareness about physical exercise and Ensuring the construction of school sports facilities. It is hoped that this study can provide some reference for the empirical analysis and intervention research on the influencing factors of college students' physical health.

Abstract
The glucose transporter 4 (GLUT4) translocation is a vital link of insulin-induced glucose uptake in adipose tissue and skeletal muscle. It is an important topic in anti-diabetic research to explore novel agents to facilitate the role of insulin. The aim of this study was to verify the hypothesis that neuropeptide galanin may enhance insulin-induced GLUT4 translocation to increase glucose uptake in adipose tissue of type 2 diabetic models. Insulin and/or galanin were injected respectively or cooperatively into type 2 diabetic rats once a day for fifteen days. The results showed that administration of galanin significantly enhanced insulin-induced GLUT4 and vesicle-associated membrane protein 2 (VAMP2) translocation, Akt phosphorylation and glucose uptake, but not GLUT4 mRNA and protein expression levels in adipose cells. The beneficial roles of galanin on insulin-induced events may be blocked by MK-2206, an Akt inhibitor, indicating that the Akt phosphorylation is essential for promoting impact of galanin on the insulin-induced events. These results suggest that galanin may benefit insulin-induced GLUT4 and VAMP2 translocation, and subsequent glucose uptake via the activated Akt-VAMP2-GLUT4 pathway in adipose cells. These findings deepen our understanding of the anti-diabetic effect of galanin and its mechanism.

Abstract
Fibulin-3(FBLN3) levels are different in different types of cancers. We found that fibulin-3 was downregulated in colorectal (CRC) cells, particularly in the SW480 cell line. By comparison, transfecting SW480 cells with a lentivirus overexpressing fibulin-3 RNA could inhibit proliferation, induce G1/S arrest, and promote cell apoptosis. Fibulin-3 overexpression further suppressed the invasion and metastasis of CRC. These effects were regulated through the AKT/mTOR signaling pathway.

Abstract
Oral squamous cell carcinoma (OSCC) is the most frequent oral cancer in the world, accounting for more than 90% of all oral cancer diagnosis. Circular RNAs (circRNAs) are large types of non-coding RNAs, demonstrating a great capacity of regulating the expression of genes. However, most of the functions of circRNAs are still unknown. Recent research revealed that circRNAs could serve as a miRNA-sponge, consequently regulating the expression of target genes indirectly, including oncogenes. In this study, we built an apoptotic model with TNF-α, and then we confirmed a circRNA associated with the apoptosis of OSCC cells, circDOCK1 by comparing the expression profile of circRNAs in an apoptotic model with that in untreated OSCC cells. We ascertained the presence of circDOCK1 with qRT-PCR and circRNA sequencing. The knockdown of the expression of circDOCK1 led to the increase of apoptosis. Utilizing multiple bioinformatics methods, we predicted the interactions among circRNAs, miRNAs and genes, and built the circDOCK1/miR-196a-5p/BIRC3 axis. Both the silencing of circDOCK1 with small interfering RNA and the upregulation of the expression of miR-196a-5p with mimics led OSCC cells to increase apoptosis and decrease BIRC3 formation. We further confirmed this outcome by comparing the expression of circDOCK1, miR-196a-5p and BIRC3 in oral squamous carcinoma tissue with those in para-carcinoma tissue, and examining the expression profile of circRNAs in oral squamous carcinoma tissue and para-carcinoma tissue with microarray. Our results demonstrated that circDOCK1 regulated BIRC3 expression by functioning as a competing endogenous RNA (ceRNA) and participated in the process of OSCC apoptosis. Thus, we propose that circDOCK1 could represent a novel potential biomarker and therapeutic target of OSCC.

Abstract
OBJECTIVE To investigate the optimal anticoagulation methods and monitoring strategy for Chinese patients undergoing heart valve replacement, which is potentially quite different from western populations. METHODS In this multicenter prospective cohort study, the anticoagulation and monitoring strategy data was acquired from 25 773 in-hospital patients in 35 medical centers and 20 519 patients in outpatient clinic in 11 medical centers from January 1st, 2011 to December 31th, 2015. RESULTS As for in-hospital patients, mean age of study population was (48.6±11.2) years old; main etiology of valve pathology was rheumatic (87.5%) origin among study cohort; 94.8% of study population received mechanical valve implantation; international normalized ratio (INR) monitoring (in all the study centers) and low-intensity anticoagulation strategy (31 hospitals chose target INR range of 1.5-2.5, and actual values of INR among 89.2% of 100 069 in-hospital monitoring samples were 1.5-2.5), with mean actual INR values of 1.84±0.53, and warfarin dosage of (2.82±0.93) mg/d were widely adopted among the study centers; strategies of in-hospital warfarin administration were similar in all the study centers; complication rates of low-intensity anticoagulation strategy were low in severe hemorrhage (0.02%), thrombosis (0.05%), and thromboembolism (0.05%) events, without anticoagulation-related death.As for 18 974 outpatient clinic patients, the follow-up rate was 92.47%, with a total of 30 012 patient-years (Pty). Anticoagulation-related morbidity and mortality rates were 0.67% and 0.15% Pty; major hemorrhage morbidity and mortality rates were 0.25% and 0.13% Pty; thromboembolism morbidity and mortality rates were 0.45% and 0.03% Pty.The mean dosage of warfarin daily dosage was (2.85±1.23) mg/d and INR value was 1.82±0.57.No significant regional difference in the intensity of anticoagulation therapy was noted during the study. CONCLUSIONS INR can be used as a normalized indicator for intensity of anticoagulation therapy in China.The optimal anticoagulation intensity with INR range from 1.5 to 2.5 is safe and effective for Chinese patients with heart valve replacement, and there is no significant regional difference in the intensity of anticoagulation therapy.

Abstract
BACKGROUND Obesity is strongly linked to increased blood pressure, which increases the risk of cardiovascular diseases. To our knowledge, little literature reported the information about galanin levels in obese individuals with hypertension. Therefore, the aim of this study was to investigate the possible involvement of galanin in the pathogenesis of obese subjects with hypertension. METHODS We measured body mass index and blood pressure of 38 obese patients with hypertension, 44 obese controls with normal blood pressure and 44 lean controls with normal blood pressure. Blood samples from all cases were collected at 8:00 a.m. after an overnight fast to determine the fasting plasma concentration of galanin, glucose, insulin, triglyceride, total cholesterol, high- and low-density lipoprotein cholesterol. RESULTS We found that plasma galanin levels were significantly decreased in obese patients with hypertension compared with the obese control group, whereas the galanin levels were significantly increased in obese controls compared with lean controls. Furthermore, in both obese groups the galanin levels were negatively correlative to diastolic blood pressure and positively correlative to insulin and triglyceride levels, but not to heart rate. CONCLUSIONS Low galanin levels were one of characters of obese patients with high blood pressure, and this levels may be taken as a novel biomarker to predict the development of high blood pressure in obese patients.

Abstract
Isothiocyanates (ITCs) occur in many cruciferous vegetables. These compounds, which have significant anticancer actions, can induce apoptosis in different human cancer cell lines. In the present study, we investigated if allyl isothiocyanate (AITC) would induce toxicity in human breast cancer MCF-7 (estrogen receptor positive) and MDA-MB-231 (estrogen receptor negative) cells. We found that AITC stimulated reactive oxygen species and Ca[Formula: see text] production, and decreased the mitochondrial membrane potential. Activity of caspase-8, -9 and -3 was increased by AITC in both cell lines. AITC also induced mitochondrial-mediated apoptosis, as shown by cytochrome c, AIF and Endo G release from mitochondria, activation of caspase-9 and caspase-3, and formation of DAPI-positive cells. There was a significant reduction in the levels of the anti-apoptotic protein Bcl-2 along with a marked increase in the pro-apoptotic protein Bax in both cell lines. AITC induced apoptosis in human breast cancer MCF-7 cells via AIF and Endo G signaling pathways, but in MDA-MB-231 cells apoptosis occurred via the GADD153 pathway. This study has revealed novel anti-cancer mechanisms of AITC, a compound that is ordinarily present in human diets and may have potential therapeutic effects in various cancers.

Abstract
Castleman disease (CD) is an uncommon lymphoproliferative disorder and is especially rare in the retroperitoneum or perirenal area. We report the case of a 42-year-old woman in whom we found on routine physical examination a mass localized in the right abdomen without clinically important constitutional symptoms for 30 days. Abdominal ultrasound, magnetic resonance images and computed tomography scans revealed a solid mass localized just below the right kidney in the retroperitoneum. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed a right retroperitoneal mass of CD (hyaline vascular type). The patient completely recovered after surgery. Castleman disease is commonly misdiagnosed as malignant lymphoma, lymphadenitis or ectopic thymoma. So far, its diagnosis is mainly achieved via histopathological examination of surgically obtained tissue. After removal of the lesion, local CD has a good prognosis.

Abstract
AIM The aim of this study was to investigate whether alcohol withdrawal and folate administration could play a role on redox balance and metionine metabolism in heavy drinkers. METHODS The derivatives of reactive oxygen metabolites (d-ROMs), homocysteine, total thiols, vitamin B12 and folate were evaluated in a selected group of 40 consecutive chronic alcohol abusers by comparison with 44 healthy moderate drinkers, as controls. RESULTS Before alcohol withdrawal, d-ROMs were significantly higher (p<0.0001) in heavy drinkers than in controls: 368.5 (254.8-718.6) U.CARR vs 245 (200.7-360) U.CARR, respectively, median with range. Plasma homocysteine were significantly higher in alcoholics than in moderate drinkers (p<0.0001): 18 (9.5-82.2) micromol/L vs 9.1 (4.9-19.6) micromol/L, respectively. Heavy drinkers also exhibited higher serum thiols than moderate drinkers (p<0.003): 605.8 (448.2-717.7) micromol/L vs 554.8 (508.3-658.4) micromol/L, respectively. The patients showed lower plasma folate than controls (p<0.0001): 4.1 (1.9-9.7) ng/mL vs 8.8 (5.0-8.4) ng/mL, respectively, but similar vitamin B12 levels: 487 (299-786) pg/mL 621 (243-894) pg/mL. A negative correlation between homocysteine and folate was observed before withdrawal in alcoholics (r=-0.4546, p<0.038). Both serum thiols (549.7 micromol/L, range 402.4-616.6 micromol/L) and homocysteinemia (6.6 micromol/L, range 2.9-18.5 micromol/L) were significantly decreased (p<0.0001 and p<0.022, respectively) after a week of alcohol withdrawal and folate administration. CONCLUSION Our findings show that both enhanced pro-oxidant activity and a derangement of methionine metabolism can be observed in heavy drinkers before alcohol withdrawal and folate administration. Furthermore, folate seems to be a strong determinant of both plasma homocysteine and thiol concentrations.

Abstract
OBJECTIVE Over the last decade, various hypotheses have been advanced concerning the cognitive functions affected by chronic alcoholism. The aim of this study was to identify the pattern of executive function impairment in chronic alcoholism, shedding light on possible differences between specific functions related to the frontal lobe. METHODS Twenty-two male alcoholics and 22 controls, matched for age, educational level and IQ, were enrolled in the study. MMPI and a battery of neuropsychological tests [i.e. digit symbol, trail making test, Stroop test, digit cancellation test, Wisconsin card sorting test (WCST), simple and choice reaction times] for assessing frontal lobe functioning were administered. RESULTS The alcoholics were found to be impaired in a wide range of executive domains, with the exception of the Stroop test, which nevertheless showed a trend towards statistically significant differences between patients and controls. CONCLUSION With the exception of aggression - our subjects did not have high aggression scale scores - the 'frontal lobe hypothesis', according to which alcoholic patients are impaired on function tests related to the frontal lobe, was therefore confirmed in our sample.

Abstract
The role of alcohol consumption on pathophysiology of atherosclerosis is not completely well established. Past studies were conducted with different methodological approaches, sometimes leading to opposing conclusions. The aim of this study was to determine the weight of alcohol intake on carotid atherosclerosis in a group of subjects asymptomatic for cardio-cerebrovascular diseases. They were examined by ultrasonographic assessment during the period 1993 through 1997. Common risk factors of atherosclerosis and drinking habit were assessed by a standardized questionnaire. In this survey we confirm the J-shaped relationship between atherosclerosis and alcohol consumption. The effect of alcohol intake is more evident if we consider the presence of multiple internal carotid stenosis, or those greater than 25%, as outcome variables. These effects are independent from the other risk factors included in logistic regression paradigms (age, arterial hypertension, dyslipidemia, diabetes mellitus, family history of cardio-cerebrovascular disease, smoking and social status). Our study supported that a high level of alcohol intake plays a role as an independent factor in carotid atherogenesis.

Abstract
BACKGROUND AND OBJECTIVES The degree of oxidative stress and its association with a thrombophilic condition, if any, were investigated in alcoholics before the onset of severe liver disease. DESIGN AND METHODS Reactive oxygen species and total antioxidant capacity were evaluated using two new kinetic spectrophotometric methods in a selected group of 45 consecutive chronic alcohol abusers and 42 apparently healthy moderate drinkers, used as controls. The hemostatic system was explored by detecting the plasma levels of prothrombin fragment 1+2 (F1+2) and thrombin-antithrombin complexes (TAT) with enzyme-linked immunosorbent assays, while D-dimer plasma levels were measured with a turbidimetric immunoassay. RESULTS Reactive oxygen species were significantly higher (p<0.001) in heavy drinkers than in controls: 328.1 (143.4-847.2) U.CARR vs 250 (200.7-366.8) U.CARR, respectively. The total antioxidant capacity was similar in chronic alcohol abusers and in moderate drinkers: 360.2 (336.8-374.4) microMol HClO/mL vs 369 (362-378.4) microMol HClO/mL, respectively. All molecular markers of hemostatic system activation were significantly increased in chronic alcohol abusers in comparison with those in moderate drinkers, as follows: TAT: 2.5 (1.4-13) microg/L vs 1.5 (1-4.1) mocrog/L, respectively (p<0.001); F1+2: 1.7 (0.5-5.2) nMol/L vs 0.9 (0.4-1.1) nMol/L, respectively (p<0.01); D-dimer: 235.5 (208-462) ng/mL vs 163.5 (71-233) ng/mL, respectively (p<0.001). INTERPRETATION AND CONCLUSIONS Our results suggest that oxidative stress and a thrombophilic condition can be observed in heavy drinkers without severe liver disease. The new test available for measuring reactive oxygen species in serum proved to be reliable and useful as an early marker of tissue damage.

Abstract
Myelolipoma is a rare benign pathology whose pathogenesis is still unclear. It is most frequently localised in the adrenal gland, followed by the presacral region, mediastinum, and perirenal and hepatic region. It varies in size from a few millimetres to several centimetres. The lesion is usually capsulated, detachable from the surrounding tissues and hypovascularised. In histological terms, it is composed of lipomatous and hematopoietic tissues. A 65-year-old female patient was referred to our unit after the finding of a nonbiopsied, pelvic mass during earlier surgery. The patient was in considerable pain owing to the extrinsic compression of the mass on abdominal and pelvic organs. Preoperative tests confirmed the presence of a voluminous presacral neoformation that appeared to have a possible medullary origin (chordoma or schwannoma). During surgery, the lesion was found to be capsulated and mainly adherent to the rectum. Histological analysis confirmed the myelolipomatous nature of the lesion. A review of 21 cases reported in the literature is presented.

Abstract
The authors discuss the influence of postmortem tissue decomposition on the lung asbestos body (AB) burden, with the aim of evaluating the reliability of data obtained from autopsies performed for medicolegal purposes several months after deaths in possible connection with asbestos-related pathology. Eight autopsy cases were selected, each one with occupational exposure considered very probable on the basis of the history or pathologic findings. In each case the AB concentrations were assessed soon after death in one lung and after periods of 1 to 18 months in the others, which had been stored in sealed containers without fixation. AB concentrations consistently decreased with time in rotten lungs. The counts in some cases became negative a few months after death, even in cases with very high AB counts at first examination. It may be reasonably inferred that, in putrefied lungs from corpses exhumed after months of internment, the counts in digested tissues and the screening of histologic sections for AB may give false-negative results.

Abstract
Asbestos bodies (AB) were harvested from human lung tissue digests and isolated from uncoated asbestos fibers. Samples containing 1000 AB were added to a reactive solution to investigate the ability of AB to oxidize deoxy-D-ribose and generate reactive oxygen species (ROS) in the presence of ascorbate and hydrogen peroxide as determined by formation of thiobarbituric acid (TBA)-reactive products. Three types of asbestos fibers were tested for comparison, since they are known to be able to produce ROS. The absorbance values measured with 1000 AB were significantly higher than those observed with 1000 fibers of the three types of asbestos. Since in our reaction system the only source of transition metals was the iron-rich AB, data suggest iron derived from the ferritin coating of AB was involved in oxidant generation. Addition of iron to AB enhanced TBA-reactive product formation, while chelation of Fe with deferoxamine reduced this reaction. Hydroxyl radical scavengers 1,3-dimethyl-2-thiourea (DMTU) and mannitol (MN) also effectively blocked TBA-reactive product generation. Data indicate the importance of Fe in AB-induced oxidant damage. With the addition of polymorphonuclear leukocytes (PMN) to AB, incubation in the reactive solution gave very high amounts of TBA-reactive products, but using a reactive solution devoid of ascorbate, very low amounts of TBA-reactive products were generated. In the latter condition, the superoxide of cell membranes probably reduced and removed iron from AB-coating ferritin, but less effectively than ascorbate. Further after the possible reoxidation of Fe2+, Fe3+ could be coordinated by lactoferrin. Since such availability of reductant is never approached in living systems, the iron in the AB coating is unlikely to function as a catalyst of Fenton-type reactions in vivo.

Abstract
OBJECTIVE To report our initial experience of the first 5 cases of partial left ventriculectomy (PLV or Batista operation), a new surgical therapy for treatment of end-stage dilated cardiomyopathy in China. METHODS From April to August 1998, 5 patients with idiopathic dilated cardiomyopathy received PLV at Anzhen Hospital. The mean age of the patients was 48.4 years (range: 42 to 53 years). Three patients were in New York Heart Association (NYHA) class III and 2 in class IV. All patients had mitral valve insufficiency (3 moderate and 2 severe) and 1 had severe tricuspid valve insufficiency in addition preoperatively. Cardiopulmonary bypass and cardiac arrest with cold blood cardioplegia were used in all patients. The average weight of the resected left ventricle muscle was 46.3 g. All patients underwent mitral annuloplasty and 1 plus tricuspid annuloplasty (De Vega). RESULTS Echocardiography demonstrated a significant decrease in left ventricular diastolic diameter (8.4 +/- 1.1 cm to 5.4 +/- 0.4 cm, P < 0.01) and an increase in ejection fraction (17.78% +/- 6.26% to 34.82% +/- 3.18%, P < 0.025). One patient died of heart failure on the 6th postoperative day. The mean follow-up period of the 4 discharged patients were 4 months (from 3 to 6 months). One were in NYHA class I and 3 in class II; all had a normal life. CONCLUSION Batista operation is a new and valuable alternative of the surgical treatment for end-stage dilated cardiomyopathy and the long-term results need further studies.

Abstract
1. Aim of the work was to verify the following three hypotheses in alcoholics: a) right hemisphere; b) diffuse brain deficit; c) anterior brain deficit, by means of a neuropsychological and a neuroradiological assessment. 2. 15 alcoholic right-hand male subjects and 15 matched controls were enrolled in the study. 3. Specifically designed neuropsychological testing was performed to investigate logical abilities, selective attention and memory. 4. Neurological investigation was performed by a standard CT scan to assess the degree and localization of brain damage. 5. Alcoholics performed worse than controls on some neuropsychological tests, i.e. Attention Matrices Test, Verbal Judgement Test, Forward Digit Span, Story Recall and Remote Memory Test. The analysis of variance adjusted by the attentional score showed no significant differences between alcoholics and controls. 6. Neuroradiological data showed a preeminent and a more frequent atrophy of the frontal region. 7. No correlations emerged between neuropsychological and neuroradiological data. 8. In conclusion, the hypothesis of anterior brain deficit seems to be confirmed by our study.

Abstract
1. The anticonvulsive efficacy of flumazenil 10 mg/kg i.v., a BDZ antagonist, was studied in two models of experimental epilepsy electrically induced. 2. The EEG after-discharge, which was induced by the electrical stimulation of selected brain regions [(notably the dorsal hippocampus (Hip) and the amygdala (CAm)] was evaluated in rabbits pre- and post-drug administration. 3. In the animals submitted to electrical stimulation of the amygdala, flumazenil exerted a protective action, thereby inducing an increase in the after-discharge threshold and/or a decrease in after-discharge duration. 4. In the animals submitted to electrical stimulation of the hippocampus, flumazenil did not induced changes statistically significant. 5. Finally, the paper discusses the two possible mechanisms of action of flumazenil (a "per se" partial BDZ activity and/or a BDZ agonistic activity, which displaces the inverse agonist-like ligand) and the differencies in GABA distribution in the hippocampus and the amygdala.

Abstract
More than 1,000 asbestos bodies/gram dry weight (AB/gdw) were found by light microscopy in lung tissues, out of 429 non selected cases of pulmonary carcinoma (264 from surgery and 165 from autopsy). Asbestosis was detected by histology in 28% of the cases with AB > 1,000/gdw (in 19% of the surgical cases, and in 38% of the autopsy cases). A proportion of 4% of the total cases may be related to asbestos exposure.

Abstract
PURPOSE Allergic conjunctivitis is a common condition caused by a mast cell-mediated hypersensitivity reaction to immunoglobulin E-bound allergens. The purpose of this study was to investigate the effect of topical cyclosporine A on the development of mast cell-mediated conjunctivitis in mice. METHODS Allergic conjunctivitis was induced in C57BL/6 mice by topical applications of compound 48/80, a mast cell degranulating agent. In two separate experiments, mice were treated with topical cyclosporine A (0.05%, 0.2%, or 0.4%), prednisolone acetate 1%, or phosphate-buffered saline. Twenty-four hours after compound 48/80 instillation, the number of neutrophils, eosinophils, lymphocytes, macrophages, and the number of preserved goblet cells and undegranulated mast cells in the conjunctiva were counted by a masked observer. RESULTS In both experiments, treatment with all three doses of cyclosporine A resulted in a statistically significant reduction in the number of infiltrating neutrophils and eosinophils compared to saline-treated controls. There was no significant difference in the treatment effect of cyclosporine and prednisolone acetate. In addition, there was increased preservation of goblet cells in the cyclosporine A-treated animals. Immunohistochemical staining showed a reduction in infiltrating lymphocytes and a smaller reduction in infiltrating macrophages in animals treated with cyclosporine compared to saline-treated controls. CONCLUSIONS Topical cyclosporine A was effective in inhibiting the development of mast cell-mediated allergic conjunctivitis in mice. This study suggests that topical cyclosporine A may be effective in treating allergic conjunctivitis in humans.

Abstract
In the laboratory, bednets impregnated with 250mg ai/m2 and 500mg ai/m2 permethrin caused respectively the mean mortalities of 86.6% within 13 months and 87.2% within 17 months on laboratory-bred An. sinensis, while they caused average mortalities of 58.3% within 4 months and 73.8% within 10 months on An. dirus respectively. The bioassay results of KT50 and LT50 on the two species showed that KT50 is shorter than LT50 after exposure to the treated bednets. The ratio is 1:2.16 - 1:3.05. It was observed Anopheles had obviously secondary knocked down after exposure to the treated bednets and there is obvious resurgent after Anopheles have been knocked down. When the temperature goes up the resurgence gets shorter, the resurgence rate gets higher and the mortality gets lower. It showed that permethrin has stronger knocking down effect than killing effect.

Abstract
1. The differential role played by blockade of D-1 or D-2 dopamine receptors in mechanisms underlying seizures was studied in a model of EEG after-discharge induced by electrical stimulation of selective brain regions (dorsal hippocampus and amygdala) in the rabbit. 2. The D-2 antagonist haloperidol (1 mg/Kg) increased significantly after-discharge duration after stimulation of either hippocampus or amygdala and lowered after-discharge threshold in few animals. 3. The D-1 antagonist SCH 23390 (0.3 mg/Kg) caused no changes following stimulation of amygdala and reduced after-discharge duration when hippocampus was stimulated. 4. Haloperidol exerted a proconvulsant action in this experimental model, having a clearer influence on D-2 receptors. SCH 23390 had no effect on amygdala whereas it exerted protection on the hippocampus. 5. The present data suggest that D-1 and D-2 receptors have different roles in generating and spreading the epileptic activity.

Abstract
Four of five members of a family complained of repeated attacks of hemiplegic migraine, migraine with aura of different types, or migraine without aura. The hemiplegia always outlasted the headache and was often accompanied by altered consciousness, aphasia, and, in one patient, coma; in this latter patient, the ictal EEG, recorded during two attacks, showed delta activity in the hemisphere contralateral to the hemiplegia. At least 2 months after their latest attacks, three patients showed dyscalculia, attentional disturbances, and impaired long-term verbal memory on neuropsychologic assessment. There were no cognitive disturbances in the unaffected relative. The severity of cognitive impairment appears to be correlated with migraine history. We attempt to classify these cases according to the criteria of the International Headache Society.

Abstract
Changes in central neurotransmission and in hypothalamo-pituitary function occur in both ethanol (ETOH) intake and withdrawal. Melatonin (MLT) secretion is regulated by the noradrenergic system, which is activated upon ETOH withdrawal. Experimental evidence exist that pineal gland may have a role in ETOH intake and preference in rats. Twenty-four hour urinary excretion of MLT was found to be increased during ETOH intake in chronic alcoholics. In this study we have determined 24h plasma levels of MLT and cortisol in 8 chronic alcoholic males hospitalized for a detoxication program and in 8 healthy controls. The study was performed just after admission, on the first day of ETOH withdrawal and after 14 days of controlled abstinence. Circadian periodicity has been evaluated by the cosinor method. The initial determinations corresponded to the acute withdrawal phase. Twenty-four hour plasma MLT mean levels on acute withdrawal were higher than after 14 days abstinence and than those found in controls. Large interindividual differences prevented the detection of statistical significance. The cosinor analysis disclosed the loss of circadian periodicity in the acute withdrawal. Significant 24h periodicity was restored after 14 days abstinence. Cortisol levels were significantly higher than those found on day 14 and in healthy controls. Twenty-four hour periodicity was maintained in both alcoholics series. A delay in cortisol acrophase occurred in acute withdrawal. The effects of Corticotropin Releasing Hormone infusion on cortisol secretion were significantly enhanced in the acute withdrawal phase in comparison with those occurring when patients were retested and with healthy controls.

Abstract
This study aimed to investigate the effects of monosialoganglioside (GM1) when administered early in a model of cerebral focal ischemia, in the rabbit. The statistical evaluation of the electroencephalographic changes (quantified EEG analysis, QEEG) due to the ischemic event showed that the early treatment (1-3-24 h) with GM1 reduced the EEgraphic pattern typical of this model of cerebral ischemia. Considering the observation period, we hypothesized that it was due to the formation of an oedema of a lesser degree compared to the untreated group. Particularly, we did not obtain the increase in delta activity on the contralateral hemisphere, which we thought was expression of the diaschisi phenomenon.

Abstract
1. EEGraphic and behavioural effects of ondansetron, a 5HT3 antagonist, have been studied in the rabbit. Subsequently we tested the neurophysiological and behavioural interactions between ondansetron and L-5-HTP induced serotonergic syndrome. 2. The drug produced a dose-dependent (0.001, 0.01, 0.1 mg/kg i.v.) increase in the cortical power density spectrum, particularly in the range of the lowest frequencies bands. This effect is expression of cortical synchronization. 3. The lowest and mild dose, but not the highest, failed to produce behavioural sedation and to inhibit the arousal induced by vibroacustical stimulation. 4. L-5-HTP (10 mg/kg i.v.) administration generated a typical EEGraphic-behavioural pattern characterized by a decrease of cortical power spectrum density and stereotyped movements. The EEGraphic effects were significantly suppressed by administration of mild and higher doses of ondansetron, while the behavioural effects were inhibited by all doses tested. 5. It is concluded that ondansetron acts with considerably efficacy on central nervous system. The administration of low and mild doses shows a singular dissociation between EEGraphic and behavioural actions. The inhibition of the L-5-HTP behavioural syndrome by ondansetron suggests that this drug acts on behaviour only when there is an altered physiological pattern.

Abstract
In this study we investigated the central effects of adinazolam, a triazolobenzodiazepine, by means of neurophysiological techniques (electroencephalogram, EEG, and quantified analysis of EEG, QEEG). The drug has been administered at the doses of 0.1-1-10 mg/kg i.v. The evaluation of the data obtained by QEEG has demonstrated that this substance acts on the central nervous system. Particularly we observed that the drug at the middle and high doses caused an increase of the "slow waves sleep" EEG pattern. This preclinical study has shown that adinazolam possesses a neuropharmacological profile similar to that of atypical antidepressive and/or anxiolytic drugs.

Abstract
It has been shown that neuroleptics which interact selectively with either D-1 or D-2 dopamine receptors possess a marked difference in their propensity on seizures. The aim of this work was to investigate whether the D-1 antagonist SCH 23390 differs from haloperidol (D-2 antagonist) in models of experimental epilepsy induced by electrical stimulation of selected brain regions (hippocampus and amygdala), in rabbits. Haloperidol increased and SCH 23390 significantly decreased the susceptibility to seizures in both models investigated. The data suggest that the D-1 and D-2 receptor subtypes have different roles in the mechanisms underlying seizures.

Abstract
We report the case of a 34-year-old man, treated by chiropractic manipulation for tension-type headache. The patient complained of a sharp occipital pain during the first session, followed by vomiting and loss of consciousness, and remained comatose for five days. Neurological examination detected persistence of dysarthria, ataxia, with delayed responses. Neuroradiological findings reveal an ischemic lesion in left PICA region, confirmed by angiography. Clinical and radiological findings suggested complete remission about two months later.

Abstract
Types of anaesthesia in different experimental models of ischemia vary, with consequent difficulties in analysis of results obtained by the authors. The aim of this work was to evaluate EEG and SEPs parameters in a group of rabbits submitted to anaesthesia with halothane. We used White New Zealand rabbits prepared for EEG recording according to the Monnier and Gangloff's stereotaxic method. SEPs were obtained by medial nerve stimulation according to a method standardized in our laboratory. Each animal was anaesthetized with halothane plus nitrous oxide and oxygen or halothane plus oxygen for surgical MAC, which was maintained for a time corresponding to the duration of surgical intervention. We evaluated all parameters in basal conditions and after the administration of anaesthesia until EEG and SEPs returned to basal values. Evoked potentials remained altered for a longer period of time and returned to basal levels only two hours after anaestethic suspension.

Abstract
The neuroleptics SCH 23390 and raclopride, which interact selectively with either D-1 or D-2 dopamine receptor, were studied for their effects on electroencephalographic (EEG) activity in the rabbit. Haloperidol (0.3 and 1 mg/kg intravenously, i.v.), which was used for comparison, induced synchronization of the cortical EEG activity. Spectral EEG analysis showed increase of power in the whole frequency range (0.1-38.5 Hz) and in all frequency bands in the cortex, whereas a slight decrease of slow and fast theta activity (3.7-7.2 and 7.2-12.2 Hz) was observed in the hippocampus. Animals appeared sedated and arousal response to somatosensory stimuli was markedly inhibited. SCH 23390 (0.03 and 0.3 mg/kg i.v.) induced periods of cortical synchronization and changes of spectral power qualitatively similar to those accompanying haloperidol administration. The drug slightly reduced the duration of arousal elicited by stimuli. Raclopride (1 and 3 mg/kg i.v.) induced weak EEG changes and little effect on arousal response to stimulation. There was an increase of slow wave activity which was particularly evident in the hippocampus. The data indicate that, although to a lesser degree, the D-1 receptor antagonist SCH 23390 induced EEG effects similar to those of haloperidol, whereas blockade of D-2 receptors by raclopride resulted in different patterns of EEG activity.

Abstract
Neuroendocrine dysfunctions, in part similar to those found in depression, are present in chronic alcoholism. The aim of this investigation was to evaluate the effects of chronic alcohol intake on cortisol secretion in basal conditions, after dexamethasone (DXT) suppression or corticotropin (ACTH) stimulation in 10 alcoholic men, during active drinking and after two weeks of alcohol withdrawal. The 24-hour, day- and night-time urinary cortisol and melatonin levels, and the effects of thyrotropin releasing hormone (TRH) on thyrotropin (TSH) and prolactin (PRL) secretions were studied in the same subjects. The data were correlated to the scores obtained by the Hamilton Rating Scale for depression and compared to those found in healthy subjects. Increased cortisol levels and the lack of DXT suppression of cortisol secretion are considered to be alcohol-dependent inasmuch as they disappear in most patients after alcohol withdrawal. The cortisol response to ACTH 1-24 infusion measured before and after alcohol withdrawal was similar in the patients we studied; moreover no significant difference was found between patients and controls. The increment of urine free cortisol levels in active alcoholics was not statistically significant. Urine cortisol levels became similar to those of the control subjects after alcohol withdrawal. The increased diurnal values of urine melatonin and the inversion of the physiological ratio between nocturnal and diurnal levels observed during alcohol intake became normal upon alcohol withdrawal. The TSH and PRL responses after the administration of 50 or 200 micrograms TRH were higher in alcoholics than in controls, while a blunted response is known to occur in depression.

Abstract
Primary CVT alterations and arrhythmias, occurring one hour after embolization were detected in several experiments about focal cerebral ischaemia in rabbits. 62 animals were fed on a standard diet and 15 on an atherogenic diet. Primary CVT alterations and arrhythmias occurred in 4 rabbits fed on a standard diet and in 6 rabbits fed on an atherogenic diet. These results gave statistic evidence of a relationship between more frequent and serious electrocardiographic alterations and an atherogenic diet. The information coming out of these experiments are discussed. Considering the data coming out of other experiments and the data of the literature it is supposed that the pathogenesis of "the cerebro-cardiac syndrome" is linked to several biohumoral alterations occurring after the stroke. If these alterations occur in animals (or in subjects) with damaged coronary arteries cardiac alterations occurring after the stroke are greater and more important than the cardiac alterations occurring in the same conditions in the animals in which coronary arteries are not jet damaged.
