Abstract
BACKGROUND Lupus erythematosus (LE) is a spectrum of autoimmune diseases. Due to the complexity of cutaneous LE (CLE), clinical skin image-based artificial intelligence is still experiencing difficulties in distinguishing subtypes of LE. OBJECTIVES We aim to develop a multimodal deep learning system (MMDLS) for human-AI collaboration in diagnosis of LE subtypes. METHODS This is a multi-centre study based on 25 institutions across China to assist in diagnosis of LE subtypes, other eight similar skin diseases and healthy subjects. In total, 446 cases with 800 clinical skin images, 3786 multicolor-immunohistochemistry (multi-IHC) images and clinical data were collected, and EfficientNet-B3 and ResNet-18 were utilized in this study. RESULTS In the multi-classification task, the overall performance of MMDLS on 13 skin conditions is much higher than single or dual modals (Sen = 0.8288, Spe = 0.9852, Pre = 0.8518, AUC = 0.9844). Further, the MMDLS-based diagnostic-support help improves the accuracy of dermatologists from 66.88% ± 6.94% to 81.25% ± 4.23% (p = 0.0004). CONCLUSIONS These results highlight the benefit of human-MMDLS collaborated framework in telemedicine by assisting dermatologists and rheumatologists in the differential diagnosis of LE subtypes and similar skin diseases.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Abstract
Background
Clinical significance of sarcopenia has been highlighted in patients with cardiovascular disease (CVD). Sarcopenia is generally diagnosed based on the decrease in skeletal muscle index (SMI) and the reduction of either handgrip strength or gait speed. However, SMI is difficult to measure for general physicians or cardiologists, because special, expensive equipment (i.e. bioelectrical impedance assay (BIA) or dual-energy X-ray absorptiometry) is necessary.
Purpose
The aim of this study was to seek a new, simple index to detect sarcopenia in CVD patients.
Methods
We retrospectively investigated the association of sarcopenia with physical examination data and circulating biomarkers of nutrition, inflammation, skeletal muscle homeostasis in 132 CVD patients who admitted in our hospital. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia (AWGS) guidelines using SMI measurements by BIA method.
Results
Among the screened biomarkers (e.g. hsCRP and IL-6), serum adiponectin and sialic acid was significantly higher in sarcopenic patients (n = 39) than non-sarcopenic patients (n = 93). On stepwise multivariate regression analysis, adiponectin, sialic acid, sex, age, and body mass index were independent detecting factors for sarcopenia based on AWGS criteria. ROC curve analysis revealed high accuracy for sarcopenia detection of the biomarker-based sarcopenia index (BMI), obtained from the regression formula using the independent factors (Figure). Conclusions: Novel biomarker-based sarcopenia index would be a simple, useful tool for detecting sarcopenia in CVD patients.

Abstract
SummaryWe have developed a chromogenic assay to measure the phospholipid-related procoagulant activity (PPA) in whole blood, or platelet-rich plasma. The test is based upon thrombin formation from prothrombin by prothrombinase and is designed in such a way that procoagulant lipids are rate limiting for the prothrombinase activity. In the chromogenic test PPA concentrations equivalent to 0-10 nM phospholipid vesicles containing 75% phosphatidyl choline (PC) and 25% phosphatidyl serine (PS) can be measured.The thrombin, which develops during the test, is measured with a chromogenic substrate. By the action of thrombin on this chromogenic substrate p-nitroaniline is liberated, which causes an increase in absorbance. Thrombin formed in the assay mixture activates the present platelets. This causes a linear increase of the velocity of thrombin generation during the test, i. e. a parabolic increase of product formation. For that reason the thrombin generation in time is characterized by two parameters, the basal PPA (PPA-B) of the original mixture and the increase in PPA due to platelet activation (PPA-A). To determine these figures the absorbency-data were fitted to parabolas. In most cases the contribution of PPA-A to the total amount of formed thrombin becomes considerable already after 30 s.Preliminary tests show that PPA-B activity in whole blood or platelet-rich plasma of patients with a thrombotic disorder is significantly higher than the activity of a control group of the same age.

Abstract
SummaryWe administered a dose of unfractionated heparin (UFH) and two doses of a low molecular weight heparin (LMWH) to healthy volunteers by SC injection. The doses given were: a) UFH, 5000IU, which represents 8.7 mg of >5,400 MW active heparin (ACLM) and no <5,400 active heparin (BCLM), b) enoxaparin 40 mg (3.4 mg ACLM, 2.2 mg BCLM) and c) enoxaparin 1 mg/kg body weight (on the mean 75 mg, containing 6.4 mg ACLM and 4.1 mg BCLM). We determined the effect on thrombin generation in platelet rich plasma (PRP) between 1 and 8 h after injection. UFH administration caused only a 5-8% inhibition of the thrombin potential (i. e. the area under the thrombin generation curve). Significantly higher inhibition of the thrombin potential was seen after administration of both doses of enoxaparin. To wit 9-26% at the low dose and 29-46% at the high dose. UFH injection caused a prolongation of the lag-time before the thrombin burst. Only with the high dose of enoxaparin the lag-times were significantly more prolonged with enoxaparin than with UFH.Excess amounts of platelet factor 4 (PF4) were able to neutralize completely the anti-thrombin activity in normal plasma spiked with enoxaparin as well as in plasma samples obtained after SC enoxaparin injection. With a large excess of PF4 the anti-factor Xa activity could be inhibited to a maximum of 50%. This indicates that ACLM (above critical length material, MW >5400) is neutralized completely by PF4 whereas BCLM (below critical length material, MW <5400) is not. The anti-thrombin heparin-activity, hence the ACLM fraction of heparin, was shown to have disappeared from the serum of PRP samples. The BCLM fraction was found after coagulation of PRP in concentrations that were indistinguishable from those in the PPP.We conclude that in PRP the activity of the BCLM fraction of injected LMWH remains after platelet activation. The possible role of this activity in thrombin inhibition and in the antithrombotic action of low molecular weight heparins is discussed.

Abstract
OBJECTIVE Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, with the risk of frailty and poor quality of life. This study aimed to clarify the clinical characteristics of sarcopenia and to investigate the effects of comprehensive cardiac rehabilitation (CCR), including nutrition, physical exercise and medication, in patients with cardiovascular disease (CVD). METHODS We retrospectively studied 322 inpatients with CVD (age 72±12 years). Muscle mass, muscle strength and physical performance were assessed before and after exercise training in patients with and without sarcopenia, which was defined as either a gait speed of <0.8 m/s or reduced handgrip strength (<26 kg in males and <18 kg in females), together with lower skeletal muscle index (SMI) (<7.0 kg/m2 in males and <5.7 kg/m2 in females). The actual daily total calorie and nutrient intake was also calculated. RESULTS Sarcopenia was identified in 28% of patients with CVD, these patients having a higher prevalence of symptomatic chronic heart failure and chronic kidney disease. SMI was significantly associated with protein intake and statin treatment. The ratio of peak VO2 and SMI was significantly higher in the statin treatment group. Handgrip strength, gait speed, leg weight bearing index, and nutritional intake improved after exercise training in patients both with and without sarcopenia. CONCLUSIONS The present findings suggest that CCR is a promising strategy for prevention and treatment of sarcopenia in patients with CVD.

Abstract
The purpose of this study was to explore the role of the organic anion-transporting polypeptide (OATP) 1A2, which is encoded by SLCO1A2, in the cellular uptake of the Bcr-Abl tyrosine kinase inhibitor imatinib, and the relationship between SLCO1A2 polymorphisms and the pharmacokinetics of imatinib in patients with chronic myeloid leukemia (CML). Imatinib uptake was significantly enhanced in OATP1A2-transfected human embryonic kidney (HEK) 293 cells (P = 0.002). Naringin, an OATP1A2 inhibitor, decreased the transport of imatinib in OATP1A2-transfected HEK293 cells, the human intestinal cell line Caco-2, and K562 CML cells. Linkage disequilibrium was found between the SLCO1A2 -1105G>A and -1032G>A genotypes in 34 CML patients and 100 healthy subjects. Imatinib clearance in CML patients was influenced by the SLCO1A2 -1105G>A/-1032G>A genotype (P = 0.075) and the SLCO1A2 -361GG genotype (P = 0.005). These findings suggest that imatinib is transported into cells by OATP1A2, and that SLCO1A2 polymorphisms significantly affect imatinib pharmacokinetics.

Abstract
Abstract
Fourteen Japanese laboratories validated the reproducibility of genotyping by 25 cleavage amplified polymorphic sequence (CAPS) markers for discrimination of strawberry (Fragaria ananassa Duch.) cultivars. Both the sensitivity and specificity rate of 12 markers were 100, those of another 12 were >95, and those of 1 were >90. These results indicate that the method of genotyping by the CAPS markers was highly reproducible and could provide a useful basis for practical identification of strawberry cultivars. This is the first report of the statistical validation of crop genotyping by DNA markers.

Abstract
BACKGROUND Progressive damage of cardiomyocytes with interstitial and replacement fibrosis accompanied by less inflammatory cell infiltration is observed in patients with dilated cardiomyopathy (DCM), suggesting some other mechanisms rather than necrotic cell death. HYPOTHESIS The aim of this study was to assess the possible involvement of apoptotic process in the pathogenesis of DCM and myocarditis. METHODS Endomyocardial biopsy was performed in patients with DCM (n = 9), myocarditis (n = 4), or atypical chest pain syndrome (as controls; n = 5). The TUNEL method was used for in situ detection of oligonucleosomal DNA strand breaks. RESULTS The TUNEL-positive cells were observed in three of nine patients with DCM and in all four with myocarditis, but in none of the controls. The TUNEL-positive nuclei were observed exclusively in cardiomyocytes in DCM, whereas in myocarditis they were detected mainly in interstitial cells and in a few myocytes. In DCM, interstitial fibrosis was greater in the TUNEL-positive than in TUNEL-negative patients (p < 0.05). In either DCM or myocarditis, electron microscopic examination could not reveal morphologic features of apoptosis of cardiomyocytes. CONCLUSION The DNA strand breaks were detected in cardiomyocytes in patients with DCM and mainly in interstitial cells in myocarditis. It is possible that the DNA strand breaks can be involved in mechanisms of progressive loss of functional cardiac units in these myocardial diseases.

Abstract
A 19-year-old man developed a huge coronary aneurysm and stenosis in the right coronary artery as a sequela of Kawasaki disease (KD) that resulted in recurrent episodes of myocardial infarction. Coronary ischemic events were successfully prevented after balloon angioplasty followed by coronary stent implantation into the stenotic lesion. The stent deployment may have an advantage compared with balloon angioplasty and other new devices for the treatment for patients with KD showing stenotic lesions without dense calcification.

Abstract
We report two cases of vasospastic angina associated with anaphylactic reaction caused by nonsteroidal anti-inflammatory drugs (NSAIDs). Both patients exhibited anaphylactic manifestations, such as general rash and urticaria, along with angina pectoris with electrocardiographic ST-segment elevations after suppository administration of diclofenac sodium or indomethacin, the most commonly used NSAIDs. Although these patients had normal coronary arteriograms, intracoronary administration of ergonovine or acetylcholine provoked diffuse coronary artery spasms accompanied by chest pain and ischemic ST-segment changes. It is therefore suggested that an allergic mechanism may be involved as a causative factor of the coronary artery spasm induced by NSAIDs.

Abstract
Highly pathogenic avian influenza (HPAI) H5N1 viruses are now endemic in many Asian countries, resulting in repeated outbreaks in poultry and increased cases of human infection. The immediate precursor of these HPAI viruses is believed to be A/goose/Guangdong/1/96 (Gs/GD)-like H5N1 HPAI viruses first detected in Guangdong, China, in 1996. From 2000 onwards, many novel reassortant H5N1 influenza viruses or genotypes have emerged in southern China. However, precursors of the Gs/GD-like viruses and their subsequent reassortants have not been fully determined. Here we characterize low-pathogenic avian influenza (LPAI) H5 subtype viruses isolated from poultry and migratory birds in southern China and Europe from the 1970s to the 2000s. Phylogenetic analyses revealed that Gs/GD-like virus was likely derived from an LPAI H5 virus in migratory birds. However, its variants arose from multiple reassortments between Gs/GD-like virus and viruses from migratory birds or with those Eurasian viruses isolated in the 1970s. It is of note that unlike HPAI H5N1 viruses, those recent LPAI H5 viruses have not become established in aquatic or terrestrial poultry. Phylogenetic analyses revealed the dynamic nature of the influenza virus gene pool in Eurasia with repeated transmissions between the eastern and western extremities of the continent. The data also show reassortment between influenza viruses from domestic and migratory birds in this region that has contributed to the expanded diversity of the influenza virus gene pool among poultry in Eurasia.

Abstract
A 59 year-old woman showed rapidly progressive glomerulonephritis during immunotherapy for metastatic renal cell carcinoma. She received unilateral nephrectomy and cytotoxic T lymphocyte (CTL) therapy for the treatment of retroperitoneal lymph node metastasis of renal cell carcinoma. With CTL therapy, her retroperitoneal lymph node mass decreased in size. One year after the third round of CTL therapy, her serum creatinine was increased and massive proteinuria occurred. Her renal biopsy specimen revealed necrotizing and crescentic glomerulonephritis with immune complex deposition. Her retroperitoneal lymph node mass continued to decrease in size. Consequently, for the purpose of avoiding interfering with the CTL therapy, we performed double filtration plasmapheresis (DFPP) monotherapy for removal of immune complexes without using immunosuppressive drugs or prednisolone. After 24 sessions of DFPP, her serum IgG was reduced from 3,942 mg/dL to 2,400 mg/dL, and proteinuria (from 9.0 g/day to 0.9 g/day) and renal function (serum creatinine; from 5.6 mg/dL to 2.2 mg/dL) also improved. However, 3 months after the final DFPP, she expired due to perforation of the colon. The autopsy sample of the kidney showed that most of the glomeruli were obsolescent, but immunoglobulin depositions were reduced and necrotizing lesions were diminished. In the patients with RPGN associated with renal cell carcinoma, renal functional recovery has not been observed upon immunosuppressive treatment. Consequently, plasmapheresis is considered to be one of the effective and safe methods for patients with this association. We also discuss previous reports of RPGN associated with renal cell carcinoma, or RPGN after cancer immunotherapy.

Abstract
BACKGROUND AND AIMS High levels of inducible nitric oxide synthase and nitrotyrosine in Helicobacter pylori-infected gastric mucosa may contribute to development of gastric cancer. We investigated the relation between expression of inducible nitric oxide synthase and proinflammatory cytokines in gastric mucosa and serum markers of gastritis. METHODS The study included 103 patients with H. pylori infection. We examined levels of interleukin-1beta, interleukin-6 and interleukin-8 by enzyme-linked immunosorbent assay and evaluated expression of inducible nitric oxide synthase and nitrotyrosine by immunohistochemical staining. Furthermore, we assessed serum levels of pepsinogens, gastrin, anti-parietal cell antibody, nitrite and nitrate, as markers of gastritis. RESULTS Thirty-seven of 103 (35.6%) gastric mucosa specimens showed simultaneous expression of inducible nitric oxide synthase and nitrotyrosine. In these patients (inducible nitric oxide synthase-positive group), the serum level of gastrin was significantly higher than that of the inducible nitric oxide synthase-negative group (509.5 +/- 141.5 pg/mL vs. 210.0 +/- 227.2 pg/mL; P < 0.01), whereas there were no significant differences in serum levels of pepsinogen, anti-parietal cell antibody, and nitrate and nitrite or in scores of histological gastritis. Interleukin-6 levels were significantly higher in the inducible nitric oxide synthase-positive group than in the inducible nitric oxide synthase-negative group (25.9 +/- 7.0 pg/mg protein vs. 10.6 +/- 4.9 pg/mg protein; P < 0.05). CONCLUSIONS Inducible nitric oxide synthase-producing gastritis was correlated with high levels of interleukin-6. Patients with hypergastrinaemia should be carefully followed on a long-term basis to ensure that the development of any malignancy is detected early.

Abstract
BACKGROUND/PURPOSE Androgen has been shown to regulate inguinoscrotal testicular descent. This study aims to clarify the effect of one of the major endocrine disrupters, vinclozolin (V), on both gubernacular migration and inguinoscrotal testicular descent in rats. METHODS Time-pregnant rats were segregated into 2 groups. In group I, the rats were administered 200 mg/kg/d of V by gavage on days 15 to 18 of gestation. In group II, the rats were administered the same volume of solvent and were used as controls. At birth, the anogenital distance was measured in pups, and gubernacular migration was examined at 10 days of age in some of male offspring. Next, the incidence of testicular descent and the growth of external genitalia were investigated in the remaining male offspring at 60 days of age. The chi2 test was used for statistical analysis of the results. RESULTS At birth, the anogenital distance (AGD) index decreased significantly more in group I than in group II in male offspring. However, there was no significant difference in the AGD index between the 2 groups in the female offspring. At 10 days of age, an aberrant migration of the gubernaculum was found in the 51.5% of V-treated rats in group I. At 60 days of age, the incidence of cryptorchidism was 57.7% in group I and 0% in group II (P <.05). In addition, hypospadias with cleft phallus and pseudo vagina with a blind pouch also were observed in some of the V-treated rats. CONCLUSIONS Prenatal administration with V thus caused intrauterine defects, which resulted in testicular maldescent caused by the induction of an aberrant migration of the gubernaculum associated with an abnormal extension of the processus vaginalis, and this may have been caused by the antiandrogenic effect of V in utero.

Abstract
BACKGROUND/PURPOSE Vinclozolin (V), a known antiandrogen, has been used widely to protect fruits, vegetables, and turf from fungus damage. The aim of this study was to clarify the effect of V on both the development of the spinal cord nucleus and testicular descent in rats. METHODS Pregnant rats were administered 200 mg/kg/d of V from day 16 to 18 of gestation. At 5 days of age, the genitofemoral nerve (GFN) of male pups was identified on the psoas muscle, and diamidinophenyl indole was applied to the proximal cut end of the GFN. Forty-eight hours later, the T11 to L4 level of the spinal cord was removed, and 30-microm frozen serial sections were made. Next, the spinal nuclei labeled in a retrograde fashion by diamidinophenyl indole (DAPI) were examined with a fluorescence microscope. Additional male pups survived until 60 days of age to evaluate the position of the testes. RESULTS The size of the DAPI-labeled spinal nuclei were smaller in the V-treated rats than in the control rats. The average number of the DAPI-labeled spinal nuclei decreased significantly more in the V-treated rats (176+/-33) than in the controls (247+/- 21; P <.05) during the newborn period. At 60 days of age, 15 of the 26 male rats showed either unilateral or bilateral undescended testes in the V-treated rats. The incidence of cryptorchidism was also significantly higher in the V-treated rats (57.7%) than in the controls (0%; P <.05). CONCLUSIONS The antiandrogenic effect of the prenatal administration of V inhibited the development of the GFN nucleus in the spinal cord and induced testicular maldescent in rats. These results support the hypothesis that androgens regulate the descent of the testis through GFN development.

Abstract
alpha(1)-Acid glycoprotein (AGP) is the major transport protein for cationic drugs, endogenous ligands, and some anionic drugs in plasma. Hepatic synthesis and secretion of AGP are altered during acute inflammation as well as by a number of drugs. This alteration could influence the binding of drugs and its biological function. Macrolide antibiotics are widely used in the treatment of a variety of infectious diseases. The effects of macrolide antibiotics have been studied with respect to rat AGP expression in vivo. After the individual administration of six macrolides to rats, with the exception of oleandomycin, five increased AGP levels in serum. Of these five, clarithromycin (CAM) was the most potent inducer of AGP, which reached a maximum level between 3 to 7 days after administration. CAM increased the steady-state level of AGP mRNA in liver as well as protein level in serum in a dose-dependent manner. In addition, CAM increased AGP mRNA levels in primary cultured hepatocytes. In the luciferase promoter assay, CAM potentiated dexamethasone-increased promoter activity of the AGP gene, which contained the glucocorticoid response element, in cultured rat hepatocytes, although CAM itself had no effect on its activity. The effect of CAM and dexamethasone was diminished by glucocorticoid response element deletion or mutation or by adding the antiglucocorticoid, RU486. Further, in the mouse mammary tumor virus (MMTV) promoter containing functional glucocorticoid response element, CAM potentiated dexamethasone-increased promoter activity. In the adrenalectomized rats, CAM did not increase AGP levels in serum. These findings suggest that CAM may cause transcriptional induction of AGP, at least in part, via a glucocorticoid-mediated mechanism.

Abstract
Heat shock protein 70 (Hsp70) is capable of protecting cells, tissues, organs, and animals from a subsequent, normally lethal heating, as well as from numerous disease states. Therefore, it would be of great therapeutic benefit to discover compounds that are clinically safe yet able to induce Hsp70 in patients. Carbenoxolone, an antiulcer drug, protects gastric mucosal cells against irritants in vivo and in vitro. We assessed here whether carbenoxolone induces Hsp70 expression in human cell lines. We found that carbenoxolone increased the expression of Hsp70 protein and mRNA, and Hsp70 promoter activity.

Abstract
A series of 2-alkoxyimino-N-(2-isoxazolin-3-ylmethyl)acetamides and related compounds were synthesized and their antiviral activities against human influenza A virus were assessed. Studies of the structure-activity relationships revealed the strongest antiviral activity when position-5 of the isoxazoline ring was substituted with a tert-butyl group. When the alkoxyimino moiety was substituted with a methyl, ethyl, isopropyl or allyl group, good antiviral activity was obtained. Among the geometrical isomers at the oxime moiety, the E-isomers were more active than the Z-isomers. Among the compounds examined, (E)-2-allyloxyimino-2-cyano-N-(5-tert-butyl-2-isoxazolin-3-ylmethyl)acetamide (1j) was the most active inhibitor with an EC(50) of 3 microg/mL in vitro.

Abstract
OBJECTIVE The present study was undertaken to clarify the clinical course and prognosis of adult patients with primary IgA nephropathy (IgAN), especially with mild proteinuria or mild histological alternations. PATIENTS AND METHODS A population of 735 IgAN patients whom we were able to observe for more than two years was examined. RESULTS A total of 115 patients (15.6%) was on dialysis during the observation period. The overall 5-year renal survival rate was 92.0%. On the other hand, 166 patients (22.6%) were in clinical remission. A group with mild proteinuria included 197 patients (26.8%). Forty-seven patients of this group showed minor glomerular abnormalities, whereas 12 patients with mild proteinuria showed severe mesangial involvement. Three patients with mild proteinuria were on dialysis during the observation period, whose proteinuria was increased during the clinical course. A group with minor glomerular abnormalities included 82 patients (11.2%). Forty-seven patients of this group showed mild proteinuria, of whom 12 patients showed moderate proteinuria. However, three patients with minor glomerular abnormalities who were not on dialysis showed loss of renal function. CONCLUSION These results indicated the heterogeneity of the course and prognosis in IgAN. Even if a patient's initial clinical or histological findings are comparatively mild, strict follow-up management is needed.

Abstract
Nontypeable Hemophilus influenzae (NTHi) is an important human pathogen in both children and adults. In children, it causes otitis media, the most common childhood infection and the leading cause of conductive hearing loss in the United States. In adults, it causes lower respiratory tract infections in the setting of chronic obstructive pulmonary disease, the fourth leading cause of death in the United States. The molecular mechanisms underlying the pathogenesis of NTHi-induced infections remain undefined, but they may involve activation of NF-kappa B, a transcriptional activator of multiple host defense genes involved in immune and inflammatory responses. Here, we show that NTHi strongly activates NF-kappa B in human epithelial cells via two distinct signaling pathways, NF-kappa B translocation-dependent and -independent pathways. The NF-kappa B translocation-dependent pathway involves activation of NF-kappa B inducing kinase (NIK)--IKK alpha/beta complex leading to I kappa B alpha phosphorylation and degradation, whereas the NF-kappa B translocation-independent pathway involves activation of MKK3/6--p38 mitogen-activated protein (MAP) kinase pathway. Bifurcation of NTHi-induced NIK-IKK alpha/beta-I kappa B alpha and MKK3/6--p38 MAP kinase pathways may occur at transforming growth factor-beta activated kinase 1 (TAK1). Furthermore, we show that toll-like receptor 2 (TLR2) is required for NTHi-induced NF-kappa B activation. In addition, several key inflammatory mediators including IL-1 beta, IL-8, and tumor necrosis factor-alpha are up-regulated by NTHi. Finally, P6, a 16-kDa lipoprotein highly conserved in the outer membrane of all NTHi and H. influenzae type b strains, appears to also activate NF-kappa B via similar signaling pathways. Taken together, our results demonstrate that NTHi activates NF-kappa B via TLR2-TAK1-dependent NIK--IKK alpha/beta-I kappa B alpha and MKK3/6--p38 MAP kinase signaling pathways. These studies may bring new insights into molecular pathogenesis of NTHi-induced infections and open up new therapeutic targets for these diseases.

Abstract
We examined the effect of fudosteine, a cysteine derivative, on blood flow of tracheal microvasculature increased by airway inflammation. Airway inflammation was elicited by sulfur dioxide (SO(2)) exposure for 2 weeks in rabbits. Each drug (500 mg/kg, p.o.) or 0.5% carboxymethylcellulose-Na (control group) was daily administered just before SO(2) exposure. After final SO(2) exposure was finished, blood flow of tracheal microvasculature was measured by blood perfusion monitor. Fudosteine or S-carboxymethylcysteine (S-CMC) significantly suppressed blood flow of tracheal microvasculature increased by SO(2) exposure. However, no effect of fudosteine was observed on the pharmacological microvascular response in trachea of SO(2)-exposed rabbits. On the other hand, fudosteine or S-CMC scavenged superoxide anion generated from rat neutrophils, and enzymatically generated from xanthine oxidase-acetaldehyde reaction. The results suggest that suppressive action in increased tracheal blood flow of fudosteine is due to anti-inflammatory activity, at least in part, via scavenging of superoxide anion.

Abstract
We examined the effect of fudosteine ((-)-(R)-2-amino-3-(3-hydroxypropylthio)propionic acid) on the mucociliary transport (MCT) rate in quails. The MCT rate was estimated by ash transport velocity on the tracheal mucosa of quails. Fudosteine (500 mg kg(-1), p.o.) did not affect the normal MCT rate. However, topical application of fudosteine to the tracheal mucosa dose-dependently protected the impairment of the MCT rate caused by exposure to cigarette smoke. The results suggest that fudosteine may participate in the defence mechanism in the respiratory tract against irritant gases.

Abstract
FK506 (tacrolimus) (10 mg/kg, s.c., 5 days) increased rat alpha1-acid glycoprotein (AGP) in serum and AGP mRNA in liver. FK506 potentiated the dexamethasone-increased AGP expression in primary cultured hepatocytes. In the luciferase promoter assay, FK506 potentiated the dexamethasone-increased promoter activity of the AGP gene in cultured rat hepatocytes, although FK506 alone had no effect on its activity. The combined effect of FK506 and dexamethasone was diminished by glucocorticoid responsive element (GRE) deletion and mutation or by an anti-glucocorticoid. These results indicated that FK506 causes the transcriptional induction of AGP, at least in part, via a glucocorticoid-mediated mechanism.

Abstract
The interaction between beta-adrenergic signaling and the activation of protein kinase C in alveolar type II cell plays an important role in the regulation of surfactant secretion because the combined application of beta-adrenergic agonist with protein kinase C activator to the cells stimulates the secretion synergistically. However, the mechanisms underlying the interaction are not clear. In the present study, we examined the combined effect of terbutaline with phorbol 12-myristate 13-acetate (PMA) on cytoplasmic free Ca2+ concentration ([Ca2+]i) in rat alveolar type II cells. The combined application of terbutaline with PMA to the cells rapidly increased [Ca2+]i, although neither of them affected it by itself. Similar increases of [Ca2+]i were observed in other combinations, such as terbutaline with 1-oleoyl-2-acetyl-sn-glycerol, and forskolin with PMA. Either the removal of extracellular Ca2+ or the addition of Co2+ remarkably suppressed the increase of [Ca2+]i induced by the combination of terbutaline with PMA. In addition, Co2+ inhibited the phosphatidylcholine secretion induced by the combination of terbutaline and PMA. These results suggested that the [Ca2+]i increased as a result of the interaction between formation of cyclic AMP and activation of protein kinase C in alveolar type II cells, and that the increase in [Ca2+]i was mediated by the Ca2+ influx through the plasma membrane. This mechanism to modulate [Ca2+]i may play a role in the regulation of surfactant secretion by alveolar type II cells.
