Abstract
Objective: To investigate the effect and role of the hepatitis B virus (HBV) on the expression of inhibin (PHB) in the proliferation and survival of hepatocellular carcinoma (HCC) cells. Methods: The expression of PHB in 13 pairs of HBV-infected livers, normal livers and HepG2.2.15 and HepG2 cells was detected by real-time fluorescent quantitative PCR and Western blot. Liver tissues were collected from seven patients with chronic hepatitis B before and after antiviral (tenofovir) treatment, and the expression of PHB was detected by RT-PCR and Western blot. HepG2.2.15 cells were transfected with Pcmv6-AC-GFP-PHB, and control vectors were collected. DNA content was analyzed by flow cytometry. The proliferation level of each cell group was detected using the EdU cell proliferation assay. HepG2.2.15 cells transfected with Pcmv6-AC-GFP-PHB and the control vector were cultured in serum-free medium for 6 days. Apoptosis was measured at the indicated time points using fluorescence-activated cell sorting (FACS)-based Annexin-V/PI double staining. Results: Compared with normal liver tissue, the expression of PHB in HBV-infected liver tissue was down-regulated (P < 0.01). Compared with HepG2 cells, the expression of PHB in HepG2.2.15 cells was significantly decreased (P < 0.01). The expression level of PHB in liver tissue after antiviral treatment (tenofovir) was significantly higher than that before treatment (P < 0.01). Compared with the control vector, the proliferation rate of HepG2.2.15 cells transfected with Pcmv6-AC-GFP-PHB was significantly lower than that of the control vector, and the apoptosis rate of HepG2.2.15 cells transfected with the Pcmv6-AC-GFP-PHB vector was significantly higher than the control vector (P < 0.01). Conclusion: HBV down-regulates the expression of inhibin to promote the proliferation and survival of hepatocellular carcinoma cells.

Abstract
Objective: To evaluate the improvement of papilledema and visual acuities in patients with idiopathic intracranial hypertension (IIH) after venous sinus stenting. Methods: The clinical data of 8 IIH patients who met the inclusion criteria underwent venous sinus stenting between January 2013 and December 2016 at Department of Neurosurgery, Tianjin Huanhu Hospital were analyzed retrospectively. There were 6 females and 3 males,aged (32.9±14.4)years (range:19 to 57 years).The thickness of the retinal nerve fiber layer (RNFL) was measured by optical coherence tomography. Fundus,visual acuity and visual field examination were performed before and after operation. If pressure gradient ≥10 mmHg(1 mmHg=0.133 kPa) across the venous stenosis was indicated by intraoperative pressure measurement,the patient would be treated with venous sinus stenting. Intracranial pressure was measured by lumbar puncture 3 to 7 days after operation. RNFL thickness and eye examination were detected 6 months after surgery. CT venogram was used to observe the sinus venous conditions. Paired t test was used to compare the data before and after surgery. Results: All the 8 patients underwent venous sinus stenting successfully. The mean pressure gradient across the venous stenosis was reduced from (24±9.2) mmHg to (2.6±2.0) mmHg (t=8.02,P<0.01). Intracranial pressure decreased from preoperative (41.4±12.7) cmH2O(1 cmH2O=0.098 kPa) to postoperative (12.9±3.3) cmH2O (t=7.08, P<0.01). The RNFL thickness decreased from (275.3±68.3)μm to (131.4±31.8)μm(t=5.80,P<0.05) 6 months after surgery and the baseline visual acuity was improved from(M(QR))0.24 (0.25) to 0.65 (0.23)(Z=-2.52,P<0.05).Papilledema was significantly improved in 6 patients,and no significant change in 2 patients. CT venogram indicated adjacent stent restenosis in 1 patient. Conclusion: Venous sinus stenting can effectively improve papilledema and visual acuity caused by IIH.

Abstract
Objective: To evaluate the outcomes of immediate rehabilitation of the edentulous and potential edentulous jaws with implant-supported full-arch prostheses and analyse the risk factors of the complications. Methods: This retrospective study included 273 patients treated with immediate rehabilitation of the edentulous and potential edentulous jaws with implant-supported full-arch prostheses from April 2008 to December 2018 in Department of Implantology, Peking University School and Hospital of Stomatology. The patients' sex, age, place of residence, jaw position, opposing dentition, number of implants, diameter and length of implants, abutment height and abutment angle were recorded. The survival rate of implants and marginal bone loss were calculated and analyzed. Cox proportional hazards ratio model was adopted to analyze the potential risk factors of prosthetic complications. Results: A total of 225 patients (288 jaws) and 1 260 implants were included, with 126 males and 99 females, aged (57.3±11.0) years, with a following time of (5.04±3.08) years. The 1-year cumulative survival rate of implants was 98.0% (1 235/1 260). Forty-eight implants were lost during the follow-up, with 39 implants in the maxillae and 9 implants in the mandible. The risk of implant failure of the maxillae [7.2% (39/541)] is significantly higher than that of the mandible [1.3% (9/719)] (P<0.01). Average marginal bone loss at 1 and 5 years was (0.7±0.2) mm and (1.1±0.3) mm. One hundred and twenty patients experienced prosthetic complications including screw/abutment loosening (44 cases), screw/abutment fracture (2 cases) and artificial tooth/denture base fracture (99 cases). The possibility of immediate prosthesis fracture within 6-8 months was high but declined over the following years with the final prosthesis delivered. Cox regression analysis showed that the use of 17° abutments in the anterior region was significantly related to the prosthetic complications (hazard ratio=1.797, P=0.002). Conclusions: Immediate rehabilitation of the edentulous jaws with implant-supported full-arch prostheses can be a predictable technique. The immediate prosthetic mechanical complication prevalence was high. The use of 17° abutments in the anterior region may increase the risk of screw/abutment loosening. It is necessary to review in time.

Abstract
Objective: To investigate the effect and mechanism of XTP4 gene in apoptotic hepatoblastoma HepG2 cell line. Methods: HepG2 cells were transiently transfected with small interfering RNA of XTP4 genes, plasmid pcDNA3.1/myc-His(-) A-XTP4, and hepatitis B virus X protein transactivated x gene 4 (HBX protein trans-activate gene4, XTP4) and their respective negative controls. After 48h, the overexpression and interference expression condition of XTP4 in HepG2 cells were detected by Western blot. HepG2 cells apoptosis was detected by flow cytometry. The expression levels of apoptosis-related proteins P53, Bcl-2, Bax and Caspase-3 in HepG2 cells were detected by Western blot, and Bcl-2/Bax ratio was calculated. The chemiluminescence assay was used to detect activity of caspase-3 in HepG2 cells. The measured data were presented as (x ± s), and independent sample t-test was used for comparison between the two groups. Results: HepG2 cells had successfully achieved the overexpression and interference expression of XTP4 protein. Compared with the control group, the overexpression of XTP4 in HepG2 cells had significantly decreased the number of apoptotic cells (P < 0.05), and increased Bcl-2/Bax (P < 0.05) ratio, but decreased the expression of P53 protein (P < 0.05). The protein expression of Caspase-3 and activity of caspase-3 was decreased (P < 0.05). However, interference with XTP4 expression in HepG2 cells had significantly increased the number of apoptotic cells (P < 0.05) and decreased Bcl-2/Bax (P < 0.05) ratio, but increased the expression of P53 protein (P < 0.05). The protein expression of Caspase-3 and activity of caspase-3 was increased (P<0.05). Conclusion: In HepG2 apoptosis XTP4 has inhibitory effect, and its effect on inhibiting HepG2 apoptosis may be achieved by regulating the Bcl-2/Bax ratio, and the P53 protein may be involved.

Abstract
OBJECTIVE To examine the clinical outcomes and associated prognostic factors among patients with multidrug-resistant tuberculosis (MDR-TB) in China. METHODS This retrospective study involved 243 patients with MDR-TB. All patients received standard regimens containing para-amino salicylic acid (PAS) and/or cycloserine (CS). The demographic, social and clinical characteristics of patients were recorded and the patients were followed up for 24 months. RESULTS Treatment success was closely associated with young age, non-farming occupations, shorter history or smoking, normal urine results, initial MDR-TB treatment regimen, increased haemoglobin, direct bilirubin, uric acid and thyroid stimulating hormone (TSH) levels, and lower white blood cell, neutrophil and blood platelet counts (all P < 0.05). On multivariable analysis, increased haemoglobin (hazard ratio [HR] 1.019, 95%CI 1.007-1.032, P = 0.002) and TSH levels (HR 1.002, 95%CI 1.006-1.039, P = 0.008), normal urine results (HR 1.541, 95%CI 1.008-2.358, P = 0.046) and initial MDR-TB treatment regimen (HR 2.238, 95%CI 1.090-4.597, P = 0.028) were prognostic factors for treatment success in MDR-TB. CONCLUSIONS Higher haemoglobin and TSH levels, normal urine results and initial MDR-TB treatment regimen might predict successful treatment of MDR-TB.

Abstract
The prevalence of pathogen inhibitors bacteria has motivate the study for antimicrobial compounds. Bioactive fungicide have always received considerable attention. A bacterial isolated strain HAB-5 showed antifungal activity against plant fungi. Based on morphological, physiological, biochemical and 16SrDNA sequence analysis, the strain was identified to be a Bacillus atrophaeus. This strain possessed a broad spectrum antifungal activity against various plant pathogenic fungi. Extraction of antifungal substance was performed and the crude extract had potent antifungal ability and showed great potential for swelling and inhibiting spore germination. This antifungal displayed heat stability and active in a wide pH range 5.0-10.0. Moreover no reduction was found in its activity after enzyme treatment. The toxicity test was evaluated in Danio rerio. The acute toxicity test indicated that the 24, 48, 72, 96h LC50 values of UMTLS to the zebrafish were 14.4, 13.8, 13.4, and 12.9%, respectively. Based on the results obtained in this study, antifungal substance was not toxic to zebra. Analyses of disease suppression showed that HAB-5 was effective to reduce the incidence of anthracnose symptoms on mango fruits, also prevent disease infection and protect tobacco seedling from Phytophtora nicotianae. The bioactive substance from Bacillus atrophaeus HAB-5 could be a candidate in the generation of new antifungal agents in crop.

Abstract
OBJECTIVE To investigate the effect of stimulation of Human Bronchial Epithelial Cells (HBEC) by Der p1 and PM2.5 on the expression of innate immune cell factors to find new therapeutic targets for treatment of bronchial asthma. MATERIALS AND METHODS The Der p1 antigen exposure model in the HEBC line, 16HBE-14o, was established in vitro. PM2.5 at a concentration of 50 µM/cm2, was added to these cells for 0.5 h, 1 h, 2 h and 3 h. Cells were treated with the following reagents for the indicated times: 300 ng/mL Der p1 for 21 h, 50 µM/cm2 PM2.5 for 3 h, 10 mM Nac for 3 h and PM2.5 contamination for 3 h. The experiment was divided into five groups: control (group A), Der p1 exposure group (group B), PM2.5 treated group (group C), PM2.5+Der p1 exposure group (group D), Nac+PM2.5+Der p1 exposure group (group E). ELISA method was adopted to test the expression levels of malondialdehyde, IL-25, IL-33 and thymic stromal lymphopoietin (TSLP), and Real-time RT-PCT was used to measure IL-25, IL-33 and TSLP mRNA. RESULTS The protein and mRNA levels of malondialdehyde, IL-25, IL-33 and TSLP in group D were significantly higher than those in the other groups, while the protein and mRNA levels of malondialdehyde, IL-25, IL-33 and TSLP in group E were significantly lower than those in group D (p<0.05). CONCLUSIONS PM2.5 can enhance the Der p1 antigen-induced HBEC innate immune response through the expression of IL-25, IL-33 and TSLP, which may exacerbate the occurrence rate of bronchial asthma.

Abstract
BACKGROUND Symmetrical acrokeratoderma (SAK) is characterized by brown to black hyperkeratotic patches on acral regions. Although epidermal hyperkeratosis and acanthosis are consistent pathological changes, the nature of epidermal hyperplasia is unknown. AIM To evaluate epidermal proliferation and differentiation and melanocytic density in skin lesions of SAK. METHODS Expression of keratin 10 (K10), K14, K16, involucrin, filaggrin, Ki-67, and Melan-A was detected by immunohistochemistry in eight patients with SAK, seven patients with ichthyosis vulgaris (IV) and six healthy controls (HCs). RESULTS Expression of K14, K16, involucrin and filaggrin was upregulated in patients with SAK compared with patients with IV and the HCs (P < 0.01-0.05), but K10 expression was similar for the three groups (P > 0.05). Numbers of Ki-67+ and Melan-A+ cells were higher in patients with SAK than in patients with IV and the HCs (P < 0.05). CONCLUSIONS These results demonstrate that excessive keratinocyte proliferation and abnormal differentiation contribute to epidermal hyperplasia, while melanocytic proliferation is responsible for the pigmented lesions in SAK.

Abstract
Recent genetic evidence suggests a robust association of the CARD14 single nucleotide polymorphism rs11652075 (c.C2458T/p.Arg820Trp) and other rare mutations in this gene with psoriasis. To assess whether combined data support the relationship between CARD14 rs11652075 and susceptibility to this disease, we conducted a meta-analysis. PubMed (MEDLINE), EMBASE, Web of Science, and the Cochrane Library were searched for relevant papers published in English. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effect models. Heterogeneity between studies was assessed using the Cochran's Q and I2 statistics. A total of five published studies, including 32,807 psoriasis patients and 45,458 controls, met our inclusion criteria and were included in the meta-analysis. The pooled OR of the association between the minor allele of this polymorphism and psoriasis was 0.877 (95%CI = 0.834-0.922; P < 0.001). In a stratified analysis, pooled ORs relating to European and Asian ancestry were 0.883 (95%CI = 0.822-0.948) and 0.872 (95%CI = 0.812-0.936), respectively. Those calculated for studies with case sample sizes above and below 1000 were 0.912 (95%CI = 0.870- 0.956) and 0.824 (95%CI = 0.734-0.924), respectively. No publication bias was present, and the exclusion of any single dataset did not substantially alter the corresponding pooled ORs. Due to the limited data available regarding clinical classification of cases and genotypes, subgroup stratification by clinical type was not performed. Our results demonstrate a significant association between the CARD14 rs11652075 polymorphism and psoriasis.

Abstract
Dystrophic epidermolysis bullosa pruriginosa (DEB-Pr) is a rare subtype of dystrophic epidermolysis bullosa (DEB). This disease is characterized by severe itching, lichenoid nodules or prurigo-like lesions, and linear scarring with a predilection for the extensor limbs. Pathogenic mutations in the type VII collagen alpha 1 (COL7A1) gene have been identified. We analyzed mutations in the COL7A1 gene in a Chinese family including 5 affected individuals with typical DEB-Pr and in a patient previously reported with sporadic DEB-Pr. The entire coding region and exon-intron boundaries of COL7A1 were detected by polymerase chain reaction and direct sequencing. We identified one novel heterozygote mutation (c.6842G>T, p.G2281V) and a second mutation (c.5443G>A, p.G1815R) reported previously in patients with DEB. Our findings contribute to the COL7A1 mutation database and further reveal the genetic and phenotypic heterogeneity of DEB-Pr.

Abstract
Six cases of eruptive vellus hair cysts (EVHC) were evaluated for histopathology and the immunohistochemical profile of Ki-67 and four keratins (K10, K14, K17 and K19). The pathological hallmark of EVHC was the existence of vellus hair shafts within the cystic cavity, but atypical pathological changes included two or three cysts and a foreign-body granuloma in three cases. Our results demonstrate that atypical pathological changes are not uncommon in EVHC, and indicate that based on keratin expression, it is likely that EVHC is derived from the infrainfundibulum and sebaceous duct.

Abstract
BACKGROUND There have been inconsistent results reported for leptin levels in patients with psoriasis. AIM To evaluate leptin levels in patients with psoriasis using a meta-analysis of studies comparing leptin levels in controls and in patients with psoriasis. METHODS PubMed (MEDLINE), EMBASE and the Cochrane Library were searched for relevant papers published in English. Pooled weighted mean differences (WMDs) and 95% CIs were calculated using random-effects and fixed-effects models. Heterogeneity between studies was assessed using the Cochran Q and I(2) statistics. RESULTS In total, 11 studies, comprising 773 patients with psoriasis and 570 healthy controls, were identified. Leptin levels were significantly higher in patients with psoriasis compared with controls (WMD = 7.24, 95% CI 4.55-9.93; P < 0.001). On stratified analysis, significant differences in leptin levels between patients with psoriasis and controls were reported only in serum samples (P < 0.001), and not in plasma samples (P = 0.025). Sensitivity analysis showed that there were no changes in the direction of effect when any one study was excluded. No publication bias was detected. CONCLUSIONS Leptin levels are higher in patients with psoriasis compared with those in controls. Future studies are warranted to clarify the association between leptin levels and the pathomechanism of psoriasis.

Abstract
Dyschromatosis symmetrica hereditaria (DSH) is an autosomal dominant pigmentary genodermatosis, characterized by a mixture of hyperpigmented and hypopigmented macules that are mainly present on the dorsal portions of the extremities. The DSH locus was mapped to chromosome 1q11-q12 and, subsequently, pathogenic mutations in the double-stranded RNA-specific adenosine deaminase (ADAR1) gene were identified. We performed a mutational analysis of the ADAR1 gene in a Chinese family that included three individuals affected with typical DSH phenotypes. Mutations within the entire coding region and the exon-intron boundaries of ADAR1 were detected and confirmed by polymerase chain reaction and direct sequencing, respectively. An insertion mutation within exon 12, c.3035_3036insC (p.P1012fsX1017), was identified in all family members affected by DSH, but not in the healthy members or 100 unrelated controls. This finding improves our understanding of the role of ADAR1 in DSH.

Abstract
The pathogenicity of a clinical isolate of Cladosporium sphaerospermum was determined in a murine model. BALB/c mice were given two intraperitoneal injections of 150 mg/kg cyclophosphamide or normal saline on days 4 and 1 preinoculation, and were then challenged with 0.2 ml of C. sphaerospermum inoculum (2 × 10(7) CFU/ml) by topical application on an abrasive wound or by subcutaneous or intravenous injection. Histopathology and inverse fungal culture were performed on the skin lesions and viscera, and pulmonary fungal burden was also determined. Inoculated skin developed localized infections after dermabrasive or subcutaneous challenge in all mice, but the maximum area and number of positive cultures from skin lesions were higher for immunocompromised mice. In the intravenously inoculated mice, all immunocompetent animals survived for the 4-week period of the experiment, while 60% of immunocompromised animals died by 5 days postinoculation. The incidence of disseminated infection and the pulmonary fungal burden of immunosuppressed mice were higher than those of immunocompetent animals. Cutaneous and systemic infections can be established by subcutaneous and intravenous challenge with C. sphaerospermum in BALB/c mice, with the lungs being the most susceptible tissue in systemic infection.

Abstract
Exophiala spinifera can induce both phaeohyphomycosis and chromomycosis. To date there have been 18 human infections caused by E. spinifera in the English literature. A case of E. spinifera-induced phaeohyphomycosis in a patient with systemic lupus erythematosus (SLE) is described. Direct microscopic examination of the pus showed branched, septate and chained hyphae and spores. A dark green velvety colony grew on Sabouraud dextrose agar. Slide culture showed branched, septate hyphae and spine-like annellated conidiophores. Histopathological biopsy revealed yellowish brown hyphae and spores. The isolate was identified as E. spinifera by DNA sequence analysis. The strain was unable to liquefy gelatin, grew at 25°C to 39°C, and was sensitive to itraconazole, amphotericin B, and terbinafine. To our knowledge, this is the first case of cutaneous phaeohyphomycosis caused by E. spinifera in SLE patients.

Abstract
X-ray photoelectron spectroscopy has been used to measure the valence band offset (VBO) of the w-InN/h-BN heterojunction. We find that it is a type-II heterojunction with the VBO being -0.30 ± 0.09 eV and the corresponding conduction band offset (CBO) being 4.99 ± 0.09 eV. The accurate determination of VBO and CBO is important for designing the w-InN/h-BN-based electronic devices.

Abstract
OBJECTIVES Delayed neuropsychiatric syndrome (DNS) is characterized by mental impairment, motor dysfunction, dementia, or psychosis that develops between a few days and weeks after acute carbon monoxide (CO) poisoning. One possible mechanism responsible for CO-mediated encephalopathy involves oxidative stress, such as lipid peroxidation, caused by the cellular uptake of CO and which leads to an inflammatory cascade. There is no current effective treatment for DNS. We applied 8-40 sessions of hyperbaric oxygen therapy (HBO2) to patients with DNS and evaluated its effectiveness. METHODS After admission, all patients were administered piracetam or bromocriptine, or both, and received HBO2. Neuropsychiatric tests included EEG, mini-mental status examination (MMSE), brain MRI, event-related potential (ERP), and brain perfusion scan (brain SPECT). Results of these tests were compared before and after HBO2, and the clinical features were monitored during this period. RESULTS The symptoms of DNS for all patients improved significantly after HBOT. Although white matter changes remained evident in the brain MRI scans, other examinations such as EEG, MMSE, ERP, and 99mTc-ECD brain SPECT were nearly normal after HBOT. CONCLUSION Our results suggest that HBO2 decreases the severity of impairment in patients with DNS. Although a large randomized trial is required to address the efficacy of this therapy, therapeutic application of HBO2 may be recommended in patients with DNS after CO poisoning.

Abstract
The common C-480T polymorphism (rs1800588) of the hepatic lipase gene (LIPC) has been associated with high-density lipoprotein (HDL) cholesterol, atherosclerosis, and coronary artery disease. In this study, we examined whether the polymorphism is associated with serum lipid and lipoprotein concentrations, as well as with subclinical atherosclerosis in Young Finns. The participants comprised 2041 men and women (aged 24-39 years) enrolled in the Cardiovascular Risk in Young Finns Study with complete data concerning the rs1800588 polymorphism and serum lipids concentration. All participants underwent an ultrasound examination for brachial artery flow-mediated vasodilatation (FMD) and carotid artery intima-media thickness (IMT) measurement. The marker of arterial elasticity, carotid artery compliance (CAC), was also calculated by means of ultrasound and concomitant brachial blood pressure measurements. In all subjects, serum total cholesterol (p < 0.001), HDL cholesterol (p = 0.006), apolipoprotein AI (apoAI, p < 0.001), and triglyceride (p = 0.009) concentrations increased according to rs1800588 genotype in the order CC, CT, and TT. The same order applied only to apoAI after adjustment for age, body mass index, systolic and diastolic blood pressure, smoking, alcohol consumption, physical activity, diabetes, hypertension, contraceptive hormone use in women, and concentrations of glucose, insulin and C-reactive protein in men and women separately (p = 0.007 and p = 0.003, respectively). The polymorphism was also associated with HDL cholesterol, total cholesterol, and triglyceride levels in women (adjusted p = 0.004, p = 0.007 and 0.02, respectively), but not in men (p was not significant for all). No significant association between the rs1800588 and brachial FMD, carotid IMT, or CAC was found among the entire study population or among women or men separately, with or without adjustment for the above-mentioned factors. The rs1800588 is associated with serum lipid and apolipoprotein concentrations, especially in women, but does not seem to be a determinant of brachial artery FMD, carotid IMT, or CAC in young healthy adults.

Abstract
Ordered arrays of FePt nanoparticles were prepared using a diblock polymer micellar method combined with plasma treatment. Rutherford backscattering spectroscopy analyses reveal that the molar ratios of Fe to Pt in metal-salt-loaded micelles deviate from those when metal precursors are added, and that the plasma treatment processes have little influence upon the compositions of the resulting FePt nanoparticles. The results from Fourier transform infrared spectroscopy show that the maximum loadings of FeCl(3) and H(2)PtCl(6) inside poly(styrene)-poly(4-vinylpyridine) micelles are different. The composition deviation of FePt nanoparticles is attributed to the fact that one FeCl(3) molecule coordinates with a single 4-vinylpyridine (4VP) unit, while two neighboring and uncomplexed 4VP units are required for one H(2)PtCl(6) molecule. Additionally, we demonstrate that the center-to-center distances of the neighboring FePt nanoparticles can also be tuned by varying the drawing velocity.

Abstract
BACKGROUND The T allele of the hepatic lipase (HL) C-480T polymorphism was previously found to be associated with lower post-heparin plasma HL activity, atherosclerosis and risk of coronary artery disease. We studied the association of HL C-480T polymorphism with the extent of atherosclerosis at vessel-wall level in an autopsy series of middle-aged men. MATERIALS AND METHODS An autopsy cohort of 700 Caucasian Finnish men aged 33-70 years (mean 53 years), which comprised two autopsy series, collected 10 years apart during 1981-82 and 1991-92, were analysed. Areas of coronary wall covered with fatty streaks and fibrotic and complicated lesions were measured using computer-assisted planimetry and related to HL C-480T genotypes (CC, CT, and TT). RESULTS There was a significant age-by-genotype interaction on the mean percentage area of fatty streaks (P = 0.01). The HL C-480T polymorphism was a significant explanatory factor for fatty streak area in men under 53 years of age with or without age, body mass index, hypertension, diabetes, smoking, alcohol consumption, apolipoprotein E genotype, and series number as covariates. Men carrying the TT genotype had two times larger areas of fatty streaks compared to the CC carriers (8.8% vs. 4.3%, P = 0.009). However, this association disappeared in men over 53 years. The areas of more advanced atherosclerotic lesions did not vary significantly among the genotype groups. CONCLUSIONS Our results suggest that the HL C-480T polymorphism affects the formation of early coronary atherosclerotic lesions in men in their early middle age.

Abstract
The diagnosis of acute renal infarction (ARI) is often delayed or unrecognised because of its non-specific presentation and the rarity of the disease. We evaluated the clinical presentations, laboratory findings, underlying medical conditions and treatment of 18 Chinese patients with ARI who presented to the emergency department (ED) of a tertiary teaching hospital from 1995 to 2004. We identified 14 non-trauma and four trauma patients with ARI. The mean duration from the onset of symptoms to the diagnosis of ARI was 1.9 days. The prevalence of concurrent events was 39%. About 64.5% of non-trauma patients had histories of atrial fibrillation, structural heart diseases or previous embolic events. The laboratory characteristics were neither specific nor sensitive for the diagnosis of ARI. Conservative treatment, local intra-arterial thrombolytic and i.v. thrombolytic therapies were provided in nine, five and two patients respectively. Decreased effective renal plasma flow in affected kidneys was found in three of three patients. Serum creatinine (Cr) was normal or elevated not more than 25% of baseline in 16 cases. ARI may resemble many non-renal diseases; however, repeated evaluation and a high index of suspicion are required for early diagnosis. Concurrent injuries or thromboembolism in other foci should be noticed. Early contrast-enhanced computerized tomography scan should be considered for high-risk patients. Patients with ARI should be followed by functional studies rather than serum Cr level.

Abstract
137 Russians living in Estonia was screened by isoelectric focusing and immunoblotting procedures to determine the distribution of genetic variations in apolipoprotein E (apoE) and apolipoprotein A-IV (apoA-IV) genes. The apoA-IV-2 allele and epsilon4 allele frequency of the Russians tended to be lower than in most other European populations.

Abstract
The antiinflammatory activity of Terminalia catappa leaves ethanolic extract was studied using 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ear edema in acute and chronic models. A bioassay-oriented fractionation procedure showed that the activity concentrates in the chloroform fraction. Ursolic acid (1) and 2alpha,3beta,23-trihydroxyurs-12-en-28-oic acid (2), isolated from the chloroform fraction, exhibited strong antiinflammatory activities. The results suggest that the triterpenic acids 1 and 2 are responsible for the antiinflammatory activity of T. catappa leaves.

Abstract
BACKGROUND Axillary osmidrosis can be treated with many methods, but local surgery is the treatment of choice. METHODS Forty-three patients (32 females and 11 males, average age 20.3 years) were treated by partial removal of the skin and subcutaneous tissue en bloc and follicular clipping of the adjacent area. All operations were performed with local anesthesia in an outpatient setting. RESULTS Follow-up ranged from 2 to 47 months (mean: 13.4 months). Forty-one patients (95%) had good results, two (5%) were fair, and none were poor. No recurrences were seen. The wound complication rate was 3.5% for axillae and 7% for patients. There were no scar contractures or limitations of arm abduction. CONCLUSION This combined surgical method can eliminate malodor and has a low wound complication and recurrence rate. Though the transient and conspicuous scar is the chief drawback of this method, it is a simple, safe, effective and inexpensive method for treating axillary osmidrosis.

Abstract
Several clinical conditions, such as deep vein thrombosis, cerebral infarct, pulmonary infarct, skin ulcers, renal failure, and habitual abortion, are thought to be associated with the antiphospholipid syndrome. The authors describe a 32-year-old woman who had characteristics of the antiphospholipid syndrome including increased immunoglobulin G-cardiolipin antibody titers, iliofemoral vein thrombosis, pulmonary embolism, headache, visual disturbances, and habitual abortion. During hospitalization, she suddenly experienced right-sided weakness. A Tc-99m HMPAO brain scan showed the probability of a transient ischemic attack in the left frontotemporal cortex.

Abstract
The effects of edible black tree fungus (BFF) compared with aspirin on serum lipid level and experimental atherosclerosis and thrombosis in rabbits were studied. The results showed that total serum cholesterol and B-lipoprotein of the BTF group were significantly decreased (P less than 0.01) than the aspirin group and the group with neither BTF nor aspirin. There were less aortic atherosclerotic plaque and intramyocardial arterial lumen stenosis in the BTF group. The development of thrombus and platelet aggregation and thromboxane TXB2 level were inhibited both in the BTF and aspirin group (P less than 0.01). These findings indicate BTF may be used as a healthy food in preventing atherosclerosis and coronary heart disease, but its mechanism requires further investigation.
