Abstract
Background Nature-based therapy (NBT), which centers around engaging in activities within natural surroundings, has consistently demonstrated therapeutic benefits for mental health. While NBT highlights the potential of nature as a therapeutic resource for promoting mental health, there is limited knowledge regarding its underlying mechanisms. Methods Two hundred seventy-six Korean participants (204 women, mean age = 54.99 ± 23.25 years) participated in a 30-session gardening program held twice weekly for 15 weeks. Structural equation modeling with a two-wave autoregressive cross-lagged model was used to investigate the mediating effects of mindfulness. Results NBT significantly improved the mean scores of all psychological variables. The mediation model was partially confirmed, with mindfulness at post-intervention (T2) mediating the relationship between baseline (T1) depression and anxiety and post-intervention (T2) life satisfaction. However, no significant indirect effect was observed between the path from stress (T1) to life satisfaction (T2). Conclusion Mindfulness is a crucial component for improving mental health outcomes. This study underscores the need to prioritize and emphasize mindfulness practices in NBT.

Abstract
During the COVID-19 pandemic, the world population faced various mental health challenges, highlighting a need for new community-based psychosocial interventions. This study aimed to investigate the effectiveness and feasibility of Nature-Based Therapy (NBT) for the community experiencing psychological distress during the pandemic. A multi-site trial comparing NBT and control groups was conducted in Korea with 291 participants exhibiting mild to severe depression or anxiety. A total of 192 participated in 30 sessions of therapeutic gardening, while 99 remained in the control group. Psychological distress and well-being were assessed using seven measures of depression, anxiety, daily activity, life satisfaction, mindfulness, stress, and loneliness. The effect sizes (Cohen's d) of NBT compared to the control group were medium to large: depression (0.583), anxiety (0.728), daily activity (1.002), life satisfaction (0.786), mindfulness (0.645), stress (0.903), and loneliness (0.695). Multilevel analysis revealed significant Time × Group interaction effects for all measures. Pearson correlation (r = - 0.28 to 0.71) showed that changes in all variables correlated significantly with each other, with small to large effect sizes. Therapeutic alliance at post-test positively moderated the intervention effects on the outcomes. We concluded that NBT is a promising psychosocial intervention for treating psychological distress for community dwellers.

Abstract
BACKGROUND Perianal fistulas, characterised as granulomatous inflammation of fistulas around the anal canal, are associated with significant morbidity resulting in a negative impact on quality of life and a tremendous burden to the healthcare system. Treatment of anal fistulas usually consists of anal surgery; however, results of closure rates are not satisfactory especially with complex perianal fistulas, after which many patients may suffer from anal incontinence. Recently, the administration of mesenchymal stem cells (MSCs) has shown promising efficacy. Herein, we aim to explore whether MSCs are effective for complex perianal fistulas and if they have either short-term, medium-term, long-term or over-long-term efficacy. Additionally, we want to elucidate whether factors such as drug dosage, MSC source, cell type, and disease aetiology influence treatment efficacy. We searched four online databases and analysed data based on information within the clinical trials registry. The outcomes of eligible trials were analysed with Review Manager 5.4.1. Relative risk and related 95% confidence interval were calculated to compare the effect between the MSCs and control groups. In addition, the Cochrane risk of bias tool was applied to evaluate the bias risk of eligible studies. Meta-analyses showed that therapy with MSCs was superior to conventional treatment for complex perianal fistulas in short-, long- and over-long-term follow-up phases. However, there was no statistical difference in treatment efficacy in the medium term between the two methods. Subgroup meta-analyses showed factors including cell type, cell source and cell dosage were superior compared to the control, but there was no significant difference between different experimental groups of those factors. Besides, local MSCs therapy has shown more promising results for fistulas as a result of Crohn's Disease (CD). Although we tend to maintain that MSCs therapy is effective for cryptoglandular fistulas equally, more studies are needed to confirm this conclusion in the future. SHORT CONCLUSION MSCs Transplantation could be a new therapeutic method for complex perianal fistulas of both cryptoglandular and CD origin showing high efficacy in the short-term to over-long-term phases, as well as high efficacy in sustained healing. The difference in cell types, cell sources and cell dosages did not influence MSCs' efficacy.

Abstract
Although many people affected by COVID-19 suffer from some form of psychological distress, access to proper treatment or psychosocial interventions has been limited. This study aimed to examine the feasibility and preliminary effects of a therapeutic gardening program conducted during the COVID-19 pandemic. The program consisted of 30 sessions and was conducted at 10 nationwide sites in Korea from June to November 2021. Mental health and well-being were assessed using the Mental Health Screening Tool for Depressive Disorders, Mental Health Screening Tool for Anxiety Disorders, Engagement in Daily Activity Scale, brief version of World Health Organization Quality of Life, and Mindful Attention Awareness Scale. Cohen’s d value was calculated for the effect size, and a multilevel analysis was used to determine the longitudinal effects of therapeutic gardening. The effect sizes for depression, anxiety, daily activities, quality of life, and mindfulness were 0.84, 0.72, 0.61, 0.64, and 0.40, respectively. Multilevel analyses showed that all five mental health variables improved significantly over time as the therapeutic gardening program progressed. Therapeutic gardening is promising and applicable as a nature-based intervention to improve the mental health of individuals experiencing psychological distress especially in the COVID-19 pandemic.

Abstract
OBJECTIVE This meta-analysis aims to assess the susceptibility to and clinical outcomes of COVID-19 in autoimmune inflammatory rheumatic disease (AIRD) and following AIRD drug use. MATERIALS AND METHODS We included observational and case-controlled studies assessing susceptibility and clinical outcomes of COVID-19 in patients with AIRD as well as the clinical outcomes of COVID-19 with or without use of steroids and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). RESULTS Meta-analysis including three studies showed that patients with AIRD are not more susceptible to COVID-19 compared to patients without AIRD or the general population (OR: 1.11, 95% CI: 0.58 to 2.14). Incidence of severe outcomes of COVID-19 (OR: 1.34, 95% CI: 0.76 to 2.35) and COVID-19 related death (OR: 1.21, 95% CI: 0.68 to 2.16) also did not show significant difference. The clinical outcomes of COVID-19 among AIRD patients with and without csDMARD or steroid showed that both use of steroid (OR: 1.69, 95% CI: 0.96 to 2.98) or csDMARD (OR: 1.35, 95% CI: 0.63 to 3.08) had no effect on clinical outcomes of COVID-19. CONCLUSIONS AIRD does not increase susceptibility to COVID-19, not affecting the clinical outcome of COVID-19. Similarly, the use of steroids or csDMARDs for AIRD does not worsen the clinical outcome.

Abstract
BACKGROUND Endocrine complications such as impaired growth, delayed puberty, and low bone mineral density (BMD) can be associated with inflammatory bowel disease (IBD) in children and adolescents. This study was performed to investigate the frequency, characteristics, and outcomes of endocrine complications of IBD in children and adolescents. METHODS This study included 127 patients with IBD diagnosed before 18 years of age [117 with Crohn disease (CD) and 10 with ulcerative colitis (UC)]. Growth profiles, pubertal status, 25-hydroxyvitamin D3 [25(OH)D3] levels, and BMD were reviewed retrospectively. RESULTS Short stature was observed in 14 of 127 (11.0 %) with a mean height-SDS of -2.31 ± 0.72. During a 2-year follow-up period, height-SDS did not significantly improve, while weight-SDS significantly improved. Among 109 patients who were older than 13 (girls) or 14 (boys) years of age during the study period, 11 patients (10.1 %) showed delayed puberty, which was associated with low weight-SDS. Vitamin D deficiency was documented in 81.7 % (94/115) with the average 25(OH)D3 level of 14.5 ± 7.0 ng/mL. Lumbar BMD Z-score was below - 2 SDS in 25 of 119 patients (21.0 %). Height-SDS, weight-SDS, and body mass index (BMI)-SDS were lower in patients with osteoporosis than those without osteoporosis. When pediatric CD activity index scores were high (≥ 30), weight-SDS, BMI-SDS, insulin-like growth factor 1 (IGF-1)-SDS, and testosterone levels were significantly decreased. CONCLUSIONS Vitamin D deficiency and osteoporosis are common in pediatric IBD patients. As disease severity deteriorates, weight-SDS, IGF-1-SDS, and testosterone levels were decreased. Optimal pubertal development is necessary for bone health.

Abstract
Objective: To investigate the mechanism of action of peroxisome proliferator-activated receptor α (PPARα)-mediated CCAAT/enhancer binding protein homologous protein (CHOP) signaling molecule with response to inflammation in mice with acute liver failure. Methods: C57BL/6 mice were used as the research subjects, and D-galactose (D-GalN) combined with lipopolysaccharide (LPS) was injected intraperitoneally to establish a mouse model of acute liver failure. PPARα was activated by Wy-14643. CHOP expression was promoted by plasmids. Liver pathological changes and serum transaminases (ALT and AST) were detected in mice to evaluate liver function. The mRNA expression level of inflammatory factors in liver tissue was detected by real-time fluorescence quantitative PCR. LPS-stimulated macrophage was used to establish an inflammation model. PPARα and CHOP expression was inhibited by siRNA. The mRNA expression level of inflammatory factors in the cells was detected by real-time fluorescence quantitative PCR. Results: Promoted PPARα activation had inhibited liver hemorrhage and inflammation in mice with acute liver failure induced by D-GalN/LPS. In addition, the serum level of transaminases and genetic level of inflammatory factors in liver tissues were reduced (P < 0.01). CHOP accelerated expression had reversed the hepatoprotective effect of PPARα activation, aggravated liver injury, and increased inflammatory factors expression (P < 0.01). At the cellular level, the inhibition of PPARα activation had accelerated the increase of inflammatory factors (P < 0.01), while the inhibition of CHOP activation had all over again decreased the inflammatory factors (P < 0.01). Conclusion: PPARα and CHOP are important signaling molecules to regulate the inflammatory response in acute liver failure and liver injury. PPARα acceleration can down-regulate CHOP to inhibit inflammatory factors, which might play a protective role in mice with acute liver failure.

Abstract
This article aims to explore the expression and mechanism of miR-10a-5p in pancreatic cancer. MiR-10a-5p mimic, MiR-10a-5p inhibitor and negative control were transfected into human pancreatic cancer cell line SW1990. Real-time quantitative PCR technology was used to analyze the expression level of miR-10a-5p in pancreatic cancer tissues and cells. The proliferation, invasion and apoptosis of SW1990 cells in each group were detected by CCK-8 analysis, Transwell analysis, TUNEL method and flow cytometry. Targetscan7.2 was used to predict the target protein of MiR-10a-5p, and the expression of related proteins was detected by Western blot analysis. The results showed that the expression of miR- 10a-5p in cancer tissues of patients with pancreatic cancer was significantly higher than that in adjacent tissues (P <0.05). The expression of miR-10a-5p in cancer cells increased significantly, which could promote the proliferation and invasion of SW1990 cells and inhibit apoptosis (P <0.05). Overexpression of miR-10a-5p can regulate the expression of BDNF and SEMA4C. miR-10a-5p can promote the occurrence and development of pancreatic cancer by regulating the BDNF / SEMA4C pathway, and may become a molecular target for the diagnosis and treatment of pancreatic cancer in the future.

Abstract
Objective: To investigate the effect of GHRH on the cognitive function of OSAHS patients by detecting the serum GHRH levels and assessing their cognitive function in patients with OSAHS. Methods: A total of 70 moderate-severe OSAHS patientsand 32 adults with snoring from October 2013 to May 2017 were enrolled for overnight polysomnography(PSG) and cognitive function assessment. Blood samples were taken at the next morning and serum GHRH levels were measured by ELISA. Results: There was no significant difference between OSAHS group (318.73±186.66)pg/ml and control group (291.48±147.36)pg/ml. Compared with control group, the serum GHRH levels were significantly increased in OSAHS patients without cognitive impairment (370.31±197.33)pg/ml, and evidently decreased in those with cognitive impairment (193.63±70.97)pg/ml (both P<0.05). The cognitive function of OSAHS patients was influenced by serum GHRH levels (OR=0.42, 95%CI: 0.24-0.73), body mass index (OR=2.23, 95%CI: 1.03-4.79), and daily sleepiness score (OR=1.80, 95%CI: 1.04-3.09). Conclusion: Serum GHRH levels in patients with moderate-severe OSAHS may play a protective role in patients' cognitive function.

Abstract
Objective Although bariatric surgery including gastrectomy has recently emerged as a useful treatment for type 2 DM with obesity, it is not clear whether gastrectomy itself can have beneficial effects on glucose metabolism. Therefore, in this study, we investigated changes in blood glucose in patients with and without diabetes who underwent gastrectomy. Methods From Jan 2010 to May 2014, 77 patients with diabetes and 77 patients without diabetes who underwent gastrectomy at Chonbuk National University Hospital, South Korea, were included. We compared fasting plasma glucose levels and HbA1c value before and after gastric surgery. Results After gastrectomy, 59 patients (38.3%) showed reduced fasting plasma glucose levels at the 1 year point, and 80 patients (51.9%) exhibited reduced fasting plasma glucose at 3 years, irrespective of their diabetes status. Among 77 patients with diabetes, decreased fasting plasma glucose was observed in 22 (28.6%) and 46 patients (59.7%) 1 and 3 years after gastrectomy, respectively. In patients who exhibited reduced fasting plasma glucose after gastrectomy, the degree of reduced glucose was as follows: 56.4±48.5 vs 23.2±16.1 mg/dL after 1 year, 58.3±52.3 vs 18.4±13.7 mg/dL after 3 years, in DM and non-DM patient respectively. Conclusions Although there was a significant drop in mean fasting glucose after gastrectomy, not all patients experienced a drop in fasting glucose. Gastrectomy did not show a consistent association with glucose reduction in patients with and without diabetes, and in about half of the patients, fasting plasma glucose levels increased after gastrectomy. Therefore, bariatric surgery including gastrectomy needs to be performed with care in diabetes, and glucose monitoring including oral glucose tolerance tests should be done for assessing or prediction of the glucose state after gastric surgery in non-DM patients.

Abstract
Triple negative breast cancer (TNBC) is associated with aggressive behaviour and poor prognosis, but has limited treatment options. To explore novel and effective therapies against TNBC, we retrospectively analyzed the efficacy of neoadjuvant intra-arterial chemotherapy through the superior epigastric artery in the treatment of locally advanced TNBC. Fifty-one locally advanced TNBC patients who received this neoadjuvant therapy from Mar 2001 to Mar 2012 were included in this study. The superior epigastric artery was selected for cannulation to deliver chemotherapy drugs. The regimen for intra-arterial chemoinfusion consisted of 75 mg/m2 epirubicin and 75 mg/m2 docetaxel. Clinical and pathological tumor responses, disease free survival (DFS), overall survival (OS), and toxicity profiles were recorded and retrospectively analyzed. In 51 patients treated with neoadjuvant intra-arterial chemoinfusion through the superior epigastric artery, the overall response rate (ORR) was 84.3%; 16 patients achieved pathological complete response (pCR). Following surgical treatment and adjuvant chemotherapy, 5-year DFS and OS were 72.4% and 75.9%, respectively, in the study population. In addition, this neoadjuvant approach showed favorable toxicity profiles. Moreover, patients who achieved pCR showed a superior survival outcome compared with those who did not. Cox regression analysis indicated that Ki-67 expression is an independent predictor for DFS and OS. Our results suggest that intra-arterial chemotherapy through the superior epigastric artery has great therapeutic potential for the treatment of locally advanced TNBC. This approach merits further clinical evaluation and may become a novel therapeutic option for locally advanced TNBC.

Abstract
The aim of the present study was to determine the anti-proliferative and pro-apoptotic effects of dihydromyricetin (DHM) on the AGS human gastric cancer cells and their underlying mechanisms. The effects of DHM on AGS cells were evaluated by using 3-(4, 5-di-methylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), lactate dehydrogenase, and Annexin V/propidium iodide (PI) double-staining assays. The underlying mechanisms were determined by using quantitative real-time polymerase chain reaction. The results demonstrated that DHM significantly (P < 0.05) inhibited AGS cell proliferation and induced cell cytotoxicity in a dose- and time-dependent manner. Additionally, Annexin V/PI double-staining assay showed that DHM promoted cell apoptosis in both, early and late stages. Furthermore, DHM also regulated the expression of apoptotic genes such as p53 and B-cell lymphoma-2 (bcl-2) in a dose- and time-dependent manner. In conclusion, this is the first report demonstrating the anticancer and pro-apoptosis effects of DHM on AGS human gastric cancer cells. The results strongly suggest that DHM may be a potential therapeutic candidate for the treatment of gastric cancer.

Abstract
OBJECTIVE In addition to tight glucose control, early intensive therapy has been reported to be more important for the prevention of diabetic micro- and macro-vascular complications. What is not known exactly is the quantitative difference according to timing delay in glucose control and whether early period control is really better than late control in terms of diabetic peripheral neuropathy. In this study, we investigated the effect of timing differences in glucose control on the peripheral nerves in an experimental diabetic model. METHODS 5 groups (6-8 rats in each group) were comprised of normal glucose rats (designated control), rats with hyperglycemia (designated DM), rats with glucose control for the entire 28-week study period (designated DM + INS [W0-28]), rats with glucose control for the early 14-week period followed by hyperglycemia for the late 14-week period (designated DM + INS [W0-14]), and rats with hyperglycemia for the early 14-week period followed by glucose control in the late 14-week period (designated DM + INS [W15-28]). RESULTS We found that the current perception threshold (CPT) was lower in the DM + INS (W0-28) and DM + INS (W15-28) groups than in the DM + INS (W0-14) or DM groups (P<0.05). The mean myelinated fiber area of the sciatic nerve was significantly greater in the DM + INS (W0-28) and DM + INS (W15-28) groups (63.5±2.32 and 60.1±2.14 um, respectively) than in the DM + INS (W0-14) or DM groups (55.5±2.81 or 51.5±2.64 um, respectively) (P<0.05), and the intraepidermal nerve fiber (IENF) density was significantly higher in the DM + INS (W0-28) and DM + INS (W15-28) groups (6.9±0.46 and 6.8±0.11, respectively) than in the DM + INS (W0-14) or DM groups (59.5±0.32 and 5.3±0.39/mm, respectively) (P<0.05). CONCLUSION Our results indicate that continuous glucose control is necessary to alleviate peripheral nerve damage and that glycemic control during the later period may be more important than early period management. The importance of continuous glucose control, including the later period of diabetes, should therefore be emphasized in diabetic peripheral neuropathy.

Abstract
Camellia is an economically important ornamental plant that has many uses, such as in beverages, foods and medicines. We examined 15 Camellia cultivars in Wenzhou, China, using RAPD markers and measurements of three traits (petal color, flower diameter, blooming period). PCR amplification with 15 random primers produced 1935 bands, observed at 88 amplification loci; 77% of the amplified loci were polymorphic, with a mean of 4.5 polymorphic loci per primer. The similarity coefficient ranged from 0.5419 to 0.7933 among the 15 samples; the lowest value was between Manao (C. reticulata) and Feibai FR (C. japonica), and the largest value was between Chidan (C. japonica) and Yuanyang FG (C. japonica). Cluster analysis divided the 15 cultivars into two groups at the similarity coefficient of 0.65. A correlation was found between RAPD markers and petal color in the first group. No correlation was found between RAPD markers and the other traits (flower diameter, blooming period). This study provides information useful for the identification, classification, phylogenesis, and breeding of Camellia cultivars.

Abstract
Device-associated infections (DAIs) have been the major causes of morbidity and mortality of patients in intensive care units (ICUs). This study evaluated the risk factors for DAIs in ICUs. Ninety-six medical or surgical ICUs of 56 hospitals participated in the Korean Nosocomial Infections Surveillance System between July 2007 and June 2008. The occurrence of catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CABSI), and ventilator-associated pneumonia (VAP) were monitored and DAI rates were calculated. Data associated with ICU characteristics were collected and Poisson regression was used for statistical analysis. Rates of CAUTI, CABSI, and VAP were 3.87 per 1000 urinary catheter days, 2.23 per 1000 central line days, and 1.89 per 1000 mechanical ventilator days, respectively. Rates of CAUTI were higher in ICUs in Seoul (P=0.032) and ICUs of major teaching hospitals (P=0.010). The ICUs of university-affiliated hospitals showed lower CAUTI rates (P=0.013). CABSI rates were higher in Seoul (P=0.001) and in medical ICUs (P=0.026). VAP rates were lower in ICUs of hospitals with more than 900 beds compared with hospitals with 400-699 beds (P=0.026). VAP rates were higher in surgical ICUs (P<0.0001) and increased 1.13-fold with each 100-unit increase in beds per infection control professional (P=0.003). The organisational and institutional characteristics of ICUs may influence DAI rates and there is a need for improvement in the incidence of VAP, CAUTI or CABSI.

Abstract
AIM To determine changes in small nerve fibres in gastric mucosa in patients with Type 2 diabetes by morphological observation. METHODS In twenty-five non-diabetic and 21 Type 2 diabetic participants, gastric mucosal biopsy under endoscopy was performed. Innervation in gastric mucosa was detected using immunohistochemical staining. Anti-protein gene product (PGP) 9.5 positive nerves underwent morphological observation and quantitative analysis. RESULTS Small nerve fibres in gastric mucosa were shortened in the diabetic subjects. The ratio of gastric mucosal protrusions maintaining nerve fibres between gastric pits to total observed protrusions was lower in patients with Type 2 diabetes compared with the non-diabetic subjects (ratio of innervated protrusion/total protrusion: 0.49 +/- 0.12 vs. 0.89 +/- 0.06, P < 0.05). CONCLUSIONS This study sets the scene for further research to investigate the relationship between gastric mucosal nerves and autonomic neuropathy or diabetic peripheral neuropathy.

Abstract
Surgery, chemotherapy and radiotherapy have been the mainstay of colorectal cancer treatment. There is however current intense research on traditional Chinese medicine (TCM) as novel or additional treatment methods for colorectal cancer. This article reviews the current use of TCM in colorectal cancer so as to increase the awareness of colorectal surgeons. The pathogenesis of colorectal cancer according to TCM is discussed. TCM has been used successfully during the perioperative period to relieve intestinal obstruction, reduce postoperative ileus and reduce urinary retention after rectal surgery. Good results have been reported in the treatment of the complications of chemotherapy and radiation enterocolitis. Favourable results have also been shown in the use of TCM either alone or in combination with chemotherapy to treat advanced colorectal cancer. Molecular studies have shown some TCM compounds to reduce tumour cell proliferation and induce apoptosis. Although the reported results of TCM have been exciting thus far, problems of lack of consensus on treatment regimes and questions on the reliability, validity and applicability of published studies prevent its widespread use. There is now an urgent need for colorectal surgeons to work with TCM physicians in the continuing research on this 6,000-year-old art so as to realize its full potential for our patients.

Abstract
AIMS Multiple pathogenic pathways are involved in diabetic neuropathy and diverse treatments have been tried without success. The aim of this study was to assess the effect of alpha-lipoic acid on skin blood flow in patients with diabetic neuropathy. METHODS We measured skin blood flow in 13 control subjects and 19 patients with diabetic neuropathy using the laser Doppler blood flow technique. Skin blood flow and the extent of skin blood flow changes were compared before and after diabetic patients received 600 mg/day alpha-lipoic acid intravenously for 14 days. RESULTS Although no significant differences in absolute values of skin blood flow or in the extent of changes were noted, symptoms were reduced after alpha-lipoic acid treatment. CONCLUSIONS This study suggests that alpha-lipoic acid, a potent antioxidant, improves symptoms of diabetic neuropathy. Larger studies are needed to determine whether improvements in skin blood flow also occur in patients with diabetic neuropathy.

Abstract
Three isoforms of metallothionein protein induced with Zinc were isolated and purified from housefly larvae, Musca domestica, by gel filtration on Sephadex G-75, G-25 and anion exchange on DEAE-52 chromatography. Among them, one was found to possess antibacterial activity, and was further characterized by SDS-polyacrylamide gel electrophoresis, sulphydryl group determination, enzyme hydrolysis, and spectra property. Our results showed that the novel protein has the characteristics of heat-stable, low-molecular weight (6 kDa), rich-cysteine (approximately 12 cysteine residues in one molecule), metal affinity, and antibacterial activity. This paper was the first to report that metallothionein had antibacterial activity. We expect that this characteristic would give some help to investigate definite physiological functions of metallothionein.

Abstract
Vascular endothelial growth factor (VEGF) is a potent, multifunctional cytokine that contributes to angiogenesis and inflammation. Matrix metalloproteinase-9 (MMP-9) is one of the major proteolytic enzymes that degrade various components of the extracellular matrix. Few data are available on the potential relationship between VEGF and MMP-9 in the accumulation of pleural effusion. We examined levels of VEGF and MMP-9 by means of enzyme immunoassay, zymographic analysis, and Western blot analysis in the patients with liver cirrhosis, tuberculosis, or lung cancer. The levels of VEGF and MMP-9 were significantly increased in the pleural fluids and sera of patients with tuberculosis and were even higher in patients with lung cancer compared with the patients with liver cirrhosis. A significant correlation was established between the level of VEGF and the level of MMP-9 in the pleural effusion. These results suggest that overproduction of VEGF and MMP-9 is associated with accumulation of the pleural effusion in tuberculosis and lung cancer. The relationship between VEGF and MMP-9 in the pleural effusion may have a role in the pathogenesis of pleural fluid formation.

Abstract
Melanoma cells rarely contain mutant p53 and hardly undergo apoptosis by wild-type p53. By using recombinant adenoviruses that express p53 or p53-related p51A or p73beta, we tested their apoptotic activities in melanoma cells. Yeast functional assay revealed a mutation of p53 at the 258th codon (AAA [K] instead of GAA [E]) in one cell line, 70W, out of six human melanoma cell lines analyzed (SK-mel-23, SK-mel-24, SK-mel-118, TXM18, 70W, and G361). Adenovirus-mediated transfer of p53, p51A, and/or p73beta suppressed growth and induced apoptotic DNA fragmentation of SK-mel-23, SK-mel-118, and 70W cells. Interestingly, p51A induced DNA fragmentation in them more significantly than p53 and p73beta. By Western blotting we analyzed levels of apoptosis-related proteins in cells expressing p53 family members. Apoptotic Bax and antiapoptotic Bcl-2 were not significantly upregulated or downregulated by expression of p53, p51A, or p73beta, except for p53-expressing 70W cells, which contained a larger amount of Bax protein than LacZ-expressing cells. Activation of caspase-3 was demonstrated only in p51A-expressing SK-mel-118 cells. We show here that p51A can mediate apoptosis in both wild-type and mutant p53-expressing melanoma cells more significantly than p53 and p73beta. It is also suggested that in melanoma cells (i) cellular target protein(s) other than Bcl-2 and Bax might be responsible for induction of p51A-mediated apoptosis and (ii) caspase-3 is not always involved in the apoptosis by p53 family members.

Abstract
Melanogenesis cascade may be directly or indirectly linked to the dynamics of endosome-lysosome biogenesis. This study aims to identify how and to what extent the endosome-lysosome system is involved in melanosome biogenesis, by utilizing a novel melanogenesis marker, J1, which we identified in the process of developing monoclonal antibodies (MoAbs) against human melanosomes. The antigenic epitope of MoAb J1 was expressed by all of the melanotic and nonmelanotic cells examined. It was expressed primarily by granular structures located in regions proximal to the Golgi complex. Most of MoAb J1 positive granules were co-stained with melanogenic markers, tyrosinase or tyrosinase-related protein (TRP-1). The epitope of MoAb J1 was also coexpressed by most, but not all, of LGP85 (a lysosomal marker) positive granules in both melanoma and non-melanoma cells, indicating that MoAb J1 recognizes a subset of lysosomal vesicles. MoAb J1 did not, however, react with vesicles with late/early (syntaxin 8/ EEA1) endosomal markers. Further examination using fluorophore-labeled pepstatin, a marker of lysosomal luminal content, confirmed that MoAb J1 specifically recognizes the luminal surface of lysosomes. These results indicate that MoAb J1 possesses an antigen epitope that is expressed in the luminal component of prelysosomal granules which are involved in the biogenesis cascade common to both melanosomes and lysosomes. We suggest that tyrosinase family protein, tyrosinase and TRP-1 are transported to melanosomes from TGN via these prelysosomal granules after being transiently transported to late endosomes.

Abstract
The intracellular vesicular trafficking in the melanosome biogenesis (melanogenesis) is reviewed with the incorporation of our own experimental findings. The melanosome biogenesis involves four stages of melanosome maturation, which reflect the transport of structural and enzymatic proteins from Golgi (trans-Golgi network: TGN) to the melanosomal compartment and their organization therein. The major melanosomal proteins include tyrosinase gene family protein (tyrosinase and tyrosinase-related protein; TRP), lysosome-associated membrane protein (Lamp) and gp100 (pmel 17). They are glycosylated in the endoplasmic reticulum, and transported by vesicles from the TGN to the melanosomal compartment. During the formation of transport vesicles, they assemble on the cytoplasmic face of the TGN to select cargo by interacting directly or indirectly with coat proteins. Tyrosinase and TRP-1 possess the dileucine motifs at the cytoplasmic domain, to which adapter protein-3 binds to transport them from the TGN to stage I melanosomes (related to late endosomes) and then to stage II melanosomes. A number of small guanosine triphosphate-binding proteins, including rab 7, appear to be involved in this vesicular transport. Phosphatidyl inositol 3 kinase also regulates this membrane trafficking of melanosomal glycoprotein. Eumelanogenesis is controlled by melanocyte-stimulating hormone, and all three tyrosinase gene family proteins are transported from the TGN to stage II melanosomes that are elliposoidal and contain the structural matrix of filaments/lamellae. In contrast, pheomelanogenesis is primarily regulated by agouti signal protein, and only tyrosinase is transported from stage I melanosomes to stage II melanosomes that are spherical and related to lysosomes. Because of the absence of TRP-1 and TRP-2 in pheomelanogenesis, it may be suggested that tyrosinase is involved in lysosomal degradation after forming dopaquinone, to which the cysteine present in the lysosomal granule binds to form cysteinyldopas that will then be auto-oxidized to become pheomelanin.

Abstract
AIM To study the relationship of Metallothionein (MT) and antioxidases in hypoxia/reoxygenation (H/R) and hypoxic preconditioning (HPC). METHODS H/R and HPC model of rat cultured cardiomyocytes were established. Then the contents of MT and relevant changes of activities of antioxidases (SOD, CAT, GSHpx) of cardiomyocytes were determined while pretreated with the treatment: HPC. Zn2+ inducing MT or MT antibody. RESULTS In HPC and Zn2+ induced groups, all the contents of MT and the activities of antioxidases were obviously higher than those in H/R (P < 0.05, P < 0.01 respectively). While using MT, the activities of SOD were progressively increased than control (P < 0.05), CAT and GSHpx activities were lower than control (P < 0.01), but were significantly higher than those in I/R group (P < 0.01). In MT antibody groups, the activities of antioxidase were decreased extremely. CONCLUSION MT has effects on the cardiomyocytes protective role of HPC. And can afford more capacity for cardiomyocytes to tolerate the H/R damage by the mechanism of increasing the activities of antioxidase.

Abstract
The genotoxic effects of X-ray radiation on human lymphocytes were measured using the single cell gel electrophoresis (SCGE) assay (comet assay) and the cytokinesis-blocked micronucleus (CBMN) test; both were carried out in vitro on isolated human lymphocytes in order to compare the relationship and sensitivity of these two detecting methods. The radiation-doses were 0.00, 0.02, 0.05, 0.10, 0.25, 0.50, 1.00 and 2.00 Gy. In the comet assay, the average comet length (38.6+/-0.8 microm) of 0.05 Gy was significantly longer than that (29.4+/-1.1 microm) of 0 Gy (P<0.01), moreover, the average comet length increased with the dose of X-ray radiation. In the CBMN, both the average micronucleus rate (MN) and micronucleated cell rate (MNC) of 0.05 Gy were 11.5+/-4.5 per thousand, which showed no difference with that (7.5+/-0.5 per thousand) of 0 Gy (P>0.05). The lowest dose, which induced significant increase of average MN and MNC, was 0.25 Gy. The average MN and MNC rates increased with radiation-dose. The results showed that there was correlation between SCGE and CBMN, and the sensitivity of SCGE was significantly higher than that of CBMN.

Abstract
We report a patient with bowenoid papulosis (BP) involving two high-risk human papillomaviruses (HPVs) and the development of invasive squamous cell carcinoma (SCC). Our patient showed verrucous lesions on the penis, perianal area and groin that had been noted over the previous 8 years and had recurred after all therapeutic approaches. The perianal and left inguinal lesions revealed invasive SCC on histology. HPV-31 and HPV-67 sequences were detected by polymerase chain reaction from BP lesions of the perianal area and the shaft of the penis. HPV-31 has already been reported in BP as a high-risk HPV for the development of SCC, but HPV-67 is a novel one that has never been reported in BP. As HPV-67 has sequence homology to HPV-52 and HPV-58, it belongs to the family of HPV-16, a high-risk HPV group. Thus our patient showed two high-risk HPVs, i.e. HPV-31 and the novel HPV-67, which may be directly involved in the development of SCC.

Abstract
The micronuclei (MN) of peripheral blood lymphocytes from radiation-exposed people were monitored with the binucleated lymphocyte micronucleus assay (CBMN). MN rates in people with radiation-disease, radiation exposed and a control group were 12.57/1000, 4.20/1000 and 3.26/1000, respectively. The MN rate of patients with radiation-disease was significantly higher than those of other groups (P < 0.01). The difference between the radiation-exposed group and control group was not significant (P > 0.05). Meanwhile, chromosome aberrations (CA) of 3 groups were determined. The results were similar to those seen while the MN assay. CA rates were 2.06%, 0.93% and 0.69%, respectively. CA rate of the radiation-disease group was significantly higher than that of other groups (P < 0.05, P < 0.01). The difference between the radiation-exposed group and the control group was not significant (P > 0.05). The study indicates that the CBMN assay is a rapid, sensitive and accurate method which can be used to monitor a large population exposed to radiation.

Abstract
Cytokinesis-blocked micronucleus assay was applied as a biological dosimeter to detect abnormalities in human peripheral lymphocytes of thirteen students exposed to formaldehyde (FA) during a 12-week (10 h per week) anatomy class. Breathing-zone air samples collected during dissection procedures showed a mean concentration of 2.37 ppm (3.17 mg/m3). Ten students from the same school but without FA exposure served as controls. Chromosome aberrations (CA) and sister chromatid exchanges (SCE) were detected in both groups. The micronuclei (MN) rate (6.38 +/- 2.50 /1000) and CA rate (5.92 +/- 2.40%) in the FA-exposed group showed a significant increase (P < 0.01) when compared with those of the controls (3.15 +/- 1.46 /1000 and 3.40 +/- 1.57% respectively). A correlation between MN and CA in individuals was observed. SCE in the exposed group were also increased (P < 0.05), but not so greatly as MN or CA. The results indicated that FA might damage the chromosomes of human lymphocytes.

Abstract
This experiment which was divided into three items studied the relativity between normal human emotion and extrication wave of mental load (EML) in a paradigm of combining CNV feedback with EML. Fourteen young persons were taken as subjects. After Fz, Cz, Pz, P3-T5 and P4-T6 were recorded, shorter EML latency and higher EML amplitude were caused by positive emotion in comparison with those caused by negative emotion. EML changes of the five recorded points were consistent under the effects of positive and negative emotions. This experiment also discussed the question of EML brain sources. Under the emotional conditions provided in the present experiment, EML possibly can be regarded as ERP index reflecting its positive and negative attributes.

Abstract
1. Intravenous administration of leukotriene C4 (LTC4) and LTD4 (1-10 nmol kg-1) caused a dose-dependent increase in secretion of glandular-kallikrein in the bronchial washings of guinea-pigs, as measured by cleavage of a synthetic substrate and the formation of kinin. LTC4 was more potent than LTD4 and pilocarpine was much less potent than peptide leukotrienes on a molecular basis. 2. The increases in levels of glandular-kallikrein in the bronchial washings that were induced by LTC4 (3 nmol kg-1, i.v.) were almost completely inhibited by pretreatment with an antagonist of leukotrienes (ONO-1078), with an antagonist of thromboxane (S-1452), with an inhibitor of thromboxane synthetase (OKY-046), with indomethacin, with atropine or with scopolamine. These results indicate that the LTC4-induced increase in levels of glandular-kallikrein may have been mediated by the formation of thromboxane and the release of acetylcholine. 3. The increases in levels of glandular-kallikrein in the bronchial washings induced by STA2 (20 pmol kg-1, i.v.), a stable analogue of thromboxane A2, were completely blocked by pretreatment with atropine, whereas increases induced by pilocarpine (41 mumol kg-1, i.v.) were not blocked by pretreatment with indomethacin, although such increases were inhibited by atropine. This result indicates that secretion of kallikrein stimulated by LTC4 may have been mediated by the successive formation of thromboxane A2 and release of acetylcholine. 4. Intravenous administration of bradykinin (3-30 nmol kg-1) caused a dose-dependent increase in levels of glandular-kallikrein in the bronchial washings. This increase was completely inhibited by pretreatment with atropine, with indomethacin or with an antagonist of thromboxane.5. The increases in levels of glandular-kallikrein in the bronchial washings induced by LTC4 (3 nmol kg'- , i.v.) and pilocarpine (41 flmol kg- 1, i.v.) were significantly inhibited by pretreatment with an antagonist of bradykinin. These results suggest that intravenous LTC4 may increase secretion of glandular-kallikrein via formation of thromboxane A2 and release of acetylcholine in that order, and kinin released by kallikrein may enhance the rate of secretion of glandular-kallikrein.

Abstract
The fundamental deficiency and outward excess syndrome of coronary heart disease can be classified into Qi Yang deficiency with blood stasis (QYD) and Yin deficiency with blood stasis (YD). The patients showed disturbances in immunofunction manifested as marked increase of serum IgG, CIC, IC-IgG and IC-C3 levels and the percentage of B cells in the peripheral blood, while the percentages of OKT3+, OKT4+ and OKT8+ cells markedly decreased, especially the percentage of OKT8+ cells, resulting in an increase of the ratio of T4/8 and imbalance between TS and TH. The authors deem that the fundamental deficiency of coronary heart disease is related to the low cellular immunity, especially the imbalance between TS and TH cells, while outward excess of coronary heart disease is related to hyperactivity of humoral immunity.

Abstract
The circulatory effects of epidural blockade were studied in 82 hypertensive patients. To compare the circulatory responses to epidural blockade between treated and untreated hypertensive patients, patients were divided into 60 treated and 22 untreated hypertensive patients groups, and to confirm the magnitude of hemodynamic changes according to the segment of epidural approach, each group was then subdivided into 3 groups as cervical, thoracic and lumbar. The blood pressure and the pulse rate were measured before and after establishment of epidural blockade. The baseline blood pressure of untreated group was significantly higher than that of treated one (P < 0.05), but there was no difference between two groups in the initial pulse rate. At 20 min after meperidine administration to epidural space, blood pressure drop was more pronounced in untreated thoracic subgroup than in treated one (P < 0.05), but there was no significant difference in blood pressure drop between treated and untreated groups of cervical and lumbar blockade. Regarding the pulse rate change, there was no significant difference between treated and untreated cases of all the subgroups. The rate of fluid load required to maintain the adequate blood pressure in the first 20 min of epidural blockade was more in treated than in untreated cases of cervical subgroup. During surgery the administration of vasopressor agents was more frequently required to maintain blood pressure in treated and untreated thoracic subgroups, while the administration of vasodilator agents was more frequent in treated and untreated cases of cervical and thoracic subgroups. The incidence of rebound hypertension was relatively high in untreated cervical and thoracic subgroups as compared to treated ones.

Abstract
The e.p.r. spectroscopy of the nitrogenase molybdenum-iron protein from Clostridium pasteurianum was re-investigated. The sharpness of the delta Ms = +/- 3 g'z peak from the +/- 3/2 Kramer's doublet enables the observation and quantification of incompletely resolved hyperfine splittings from the stable magnetic nuclei 95Mo and 57Fe in samples enriched in these isotopes. No couplings to 1H or 17O could be discerned by examination of spectra from samples exchanged into 2H2O and H2(17)O respectively. Simulation of the spectrum from 95Mo-enriched samples yields a hyperfine coupling of 2.9 MHz, and indicates that the earlier electron-nuclear-double-resonance-derived estimate of 8.1 +/- 0.2 MHz is substantially in error.
