Abstract
Computer-aided diagnosis techniques based on deep learning in skin cancer classification have disadvantages such as unbalanced datasets, redundant information in the extracted features and ignored interactions of partial features among different convolutional layers. In order to overcome these disadvantages, we propose a skin cancer classification model named EFFNet, which is based on feature fusion and random forests. Firstly, the model preprocesses the HAM10000 dataset to make each category of training set images balanced by image enhancement technology. Then, the pre-training weights of the EfficientNetV2 model on the ImageNet dataset are fine-tuned on the HAM10000 skin cancer dataset. After that, an improved hierarchical bilinear pooling is introduced to capture the interactions of some features between the layers and enhance the expressive ability of features. Finally, the fused features are passed into the random forests for classification prediction. The experimental results show that the accuracy, recall, precision and F1-score of the model reach 94.96%, 93.74%, 93.16% and 93.24% respectively. Compared with other models, the accuracy rate is improved to some extent and the highest accuracy rate can be increased by about 10%.

Abstract
M. tuberculosis (Mtb) infects lung phagocytes including alveolar macrophages (AM) and recruited/monocyte-derived macrophages (RM). However, little is known about the distinct roles of different cell subsets in Mtb persistence, and how they differ in controlling Mtb during chronic infection. Using fluorescent reporter strains and quantitation of live bacteria by cfu plating of sorted cell subsets, we found that AM are superior to RM in restricting and killing Mtb during chronic infection (4 wk PI). Subsequent bulk RNA-Seq of live-sorted cells from infected mice reveal that genes of the lysosome pathway are under-expressed in RM compared with AM. Using functional assays, we show here that RM have poorer lysosome function than AM. Specifically, AM not only have more lysosome content, more abundant lysosomal enzyme content and activities, but also have higher expression of proteins for lysosome acidification and more acidic lysosomes. Moreover, immunofluorescence data reveal that AM have more nuclear TFEB than RM. Nuclear translocation activates TFEB, which serves as a master regulator of lysosome biogenesis. We also found that TFEB overexpressing bone marrow-derived macrophages have enhanced abilities to kill virulent Mtb. Together, these results imply that TFEB may drive the difference of lysosome functions between AM and RM, leading to the difference in killing Mtb, and that Mtb takes advantage of intrinsically lysosome-poor RM for persistence.

Abstract
Objective: To explore the clinical characteristics, intervention and treatment of tympanic osteoma at different locations. Methods: The medical history, audiological and imaging examination, operation and follow-up results of two patients with tympanic osteoma at different sites were reviewed and summarized. Furthermore, the clinical characteristics and interventions of 36 patients reported in literatures with tympanic osteomas were also summarized and analyzed. Results: Osteoma of the two patients collected in this study located at promontory and incus respectively;both of them presented with intact tympanum and conductive deafness, without obvious etiology or predisposing factor. Both of them underwent surgeries and the hearing improved significantly. For patient one, the ossicular chain was intact and restored to activity after removed the osteoma. For patient two, an artificial ossicle was implanted after removed the osteoma and incus. In the 36 patients reported in literatures, the average age was 26.5 years, and 39.47% of them located at promontory; in addition, the main symptoms of them were progressive hearing loss, tinnitus and ear stuffy. Conclusions: Patients with tympanic osteoma are characterized by conduction deafness with intact tympanic membrane, and the most common lesion is promontory. Hearing can be restored by excision of the osteoma and maintenance or reconstruction of the ossicle chain.

Abstract
OBJECTIVE Langerhans cell histiocytosis (LCH) is a rare clinical disorder. We retrospectively analysed the clinical manifestations, treatments and prognoses of LCH cases involving the ear, nose, and neck. MATERIALS AND METHODS 28 cases with confirmed LCH in ear, nose or neck were reviewed. We recorded patient age, sex, chief complaints, accompanying symptoms, lesional sites, radiological data, treatments and pathologies. Whole-exome sequencing was performed on the patient diagnosed with LCH and Treacher-Collins syndrome (TCS). RESULTS The mean age was 14.86 years. Most LCH was in the ear (93%), usually in the mastoid. The most common symptoms were an ear mass and a purulent discharge. Imaging was not very useful. Treatments included surgery, chemotherapy, and radioactive particle implantation. Some cases exhibited multisystem involvement. Most patients enjoyed good prognoses. One patient was diagnosed with both temporal LCH and TCS. Whole-exome sequencing revealed a heterozygous c.261_272delAGGTACCCTTCC(p.87_91delRGTLPinsR) mutation in exon 2 of the POLR1D gene (NM_015972). CONCLUSION LCH mostly occurs in children. In head and neck it affects principally the mastoid part of the temporal bone. Treatments include surgery, chemotherapy, and irradiation. Most patients enjoy good prognoses. LCH accompanied by TCS is rare and increases the difficulty of diagnosis; molecular data aid in TCS identification.

Abstract
Background: Patients may suffer postoperative facial nerve injury, hearing loss, or other postoperative complications after the operation, which seriously affect their postoperative life quality. Aims/objectives: To investigate the differences in QOL (quality of life) of patients with acoustic neuroma resection by the translabyrinthine or retrosigmoid approach. Material and methods: Patients with acoustic neuroma resection in our department were enrolled in this experimental study, among which fifty patients underwent the translabyrinthine approach resection, the other 50 patients underwent the retrosigmoid approach resection. Different scores by the SF-36 scale between these two groups of patients one month after discharge were then analyzed. Results: Scores of patients undergoing the retrosigmoid approach were higher in the three dimensions of Social Functioning, Role-emotional and Mental Health than those of patients undergoing the translabyrinthine approach with statistical significance. However, scores of patients undergoing the translabyrinthine approach were higher in the two dimensions of Body Pain and Vitality than those of the patients undergoing the retrosigmoid approach. Conclusions and significance: The results indicated that individual nursing interventions for different patients are necessary to improve the QOL of patients after hospitalization. Moreover, the operated patients with translabyrinthine approach were more advantage than patients with retrosigmoid approach.

Abstract
Transcription factor Hes1 acts as a homeostatic negative regulator of type I interferon production to restrain interferon-mediated immune responses, including antiviral immunity and autoimmune conditions. Mechanistically, Hes1 suppresses interferon expression by targeting a regulatory circuit composed of WDFY1 and VEGF-C. Induction of type I interferons (IFNs) is critical for eliciting competent immune responses, especially antiviral immunity. However, uncontrolled IFN production contributes to pathogenesis of autoimmune and inflammatory diseases. We found that transcription factor Hes1 suppressed production of type I IFNs and expression of IFN-stimulated genes. Functionally, Hes1-deficient mice displayed a heightened IFN signature in vivo, mounted enhanced resistance against encephalomyocarditis virus infection, and showed signs of exacerbated experimental lupus nephritis. Mechanistically, Hes1 did not suppress IFNs via direct transcriptional repression of IFN-encoding genes. Instead, Hes1 attenuated activation of TLR upstream signaling by inhibition of an adaptor molecule, WDFY1. Genome-wide assessment of Hes1 occupancy revealed that suppression of WDFY1 was secondary to direct binding and thus enhancement of expression of VEGF-C by Hes1, making Vegfc a rare example of an Hes1 positively regulated gene. In summary, these results identified Hes1 as a homeostatic negative regulator of type I IFNs for the maintenance of immune balance in the context of antiviral immunity and autoimmune diseases.

Abstract
MicroRNA-200b (miR-200b) functions as an oncogenic regulator in human lung cancer. However, the effect of miRNA-200b on the development and progression of T-Cell acute lymphoblastic leukemia (T-ALL) remains largely unknown. In this study, we evaluated the impact of miR-200b in T-ALL cell proliferation, survival and invasion using gain and loss of function approaches. Human Jurkat cells, a widely used in-vitro T-ALL cell model, were transfected with miR-200b mimic or miR-200b inhibitor. miR-200b mimics substantially inhibited Jurkat cell proliferation and invasion while significantly stimulating cell apoptosis compared to the control miRNA-treated cells. In contrast, Jurkat cells treated with anti-miR200 demonstrated induction of cell growth and invasion but repression of cell apoptosis. Such effect was accompanied by the corresponding alteration in NOTCH1 expression, suggesting that NOTCH1 might be the target gene for miR-200b function in Jurkat cells. In summary, our findings demonstrate that miR-200b may serve as a potential therapeutic target for T-ALL by negatively regulating the NOTCH1 signaling pathway.

Abstract
BACKGROUND There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment. AIM To analyze the associations of birth weight, length and ponderal index with height from infancy through adulthood within mono- and dizygotic twin pairs, which provides insights into the role of genetic and environmental individual-specific factors. METHODS This study is based on the data from 28 twin cohorts in 17 countries. The pooled data included 41,852 complete twin pairs (55% monozygotic and 45% same-sex dizygotic) with information on birth weight and a total of 112,409 paired height measurements at ages ranging from 1 to 69 years. Birth length was available for 19,881 complete twin pairs, with a total of 72,692 paired height measurements. The association between birth size and later height was analyzed at both the individual and within-pair level by linear regression analyses. RESULTS Within twin pairs, regression coefficients showed that a 1-kg increase in birth weight and a 1-cm increase in birth length were associated with 1.14-4.25 cm and 0.18-0.90 cm taller height, respectively. The magnitude of the associations was generally greater within dizygotic than within monozygotic twin pairs, and this difference between zygosities was more pronounced for birth length. CONCLUSION Both genetic and individual-specific environmental factors play a role in the association between birth size and later height from infancy to adulthood, with a larger role for genetics in the association with birth length than with birth weight.

Calcium-dependent Nedd4-2 upregulation mediates degradation of the cardiac sodium channel Nav1.5: implications for heart failure. Acta Physiol (Oxf) 2017; 221:44-58.

Abstract
AIM Reductions in voltage-gated sodium channel (Nav1.5) function/expression provide a slowed-conduction substrate for cardiac arrhythmias. Nedd4-2, which is activated by calcium, post-translationally modulates Nav1.5. We aim to investigate whether elevated intracellular calcium ([Ca2+ ]i ) reduces Nav1.5 through Nedd4-2 and its role in heart failure (HF). METHODS Using a combination of biochemical, electrophysiological, cellular and in vivo methods, we tested the effect and mechanism of calcium on Nedd4-2 and in turn Nav1.5. RESULTS Increased [Ca2+ ]i , following 24-h ionomycin treatment, decreased sodium current (INa ) density and Nav1.5 protein without altering its mRNA in both neonatal rat cardiomyocytes (NRCMs) and HEK 293 cells stably expressing Nav1.5. The calcium chelator BAPTA-AM restored the reduced Nav1.5 and INa in NRCMs pre-treated by ionomycin. Nav1.5 was decreased by Nedd4-2 transfection and further decreased by 6-h ionomycin treatment. These effects were not observed in cells transfected with the catalytically inactive mutant, Nedd4-2 C801S, or with Y1977A-Nav1.5 mutant containing the impaired Nedd4-2 binding motif. Furthermore, elevated [Ca2+ ]i increased Nedd4-2, the interaction between Nedd4-2 and Nav1.5, and Nav1.5 ubiquitination. Nav1.5 protein is decreased, whereas Nedd4-2 is increased in volume-overload HF rat hearts, with increased co-localization of Nav1.5 with ubiquitin or Nedd4-2 as indicated by immunofluorescence staining. BAPTA-AM rescued the reduced Nav1.5 protein, INa and increased Nedd4-2 in hypertrophied NRCMs induced by isoproterenol or angiotensin II. CONCLUSION Calcium-mediated increases in Nedd4-2 downregulate Nav1.5 by ubiquitination. Nav1.5 is downregulated and co-localizes with Nedd4-2 and ubiquitin in failing rat heart. These data suggest a role of Nedd4-2 in Nav1.5 downregulation in HF.

Abstract
Cancer stem-like cells (CSC) are thought to drive tumor initiation, metastasis, relapse, and therapeutic resistance, but their specific pathogenic characters in many cancers, including non-small cell lung cancer (NSCLC), have yet to be well defined. Here, we develop findings that the growth factor HGF promotes CSC sphere formation in NSCLC cell populations. In patient-derived sphere-forming assays (PD-SFA) with HGF, CD49f and CD104 were defined as novel markers of lung CSC (LCSC). In particular, we isolated a subpopulation of CD166+CD49fhiCD104-Lin- LCSC present in all human specimens of NSCLC examined, regardless of their histologic subtypes or genetic driver mutations. This specific cell population was tumorigenic and capable of self-renewal, giving rise to tumor spheres in vitro and orthotopic lung tumors in immune-compromised mice. Mechanistic investigations established that NOTCH1 was preferentially expressed in this cell subpopulation and required for self-renewal via the transcription factor HES1. Through a distinct HES1-independent pathway, NOTCH1 also protected LCSCs from cisplatin-induced cell death. Notably, treatment with a γ-secretase inhibitor that blunts NOTCH1 function ablated self-renewing LCSC activity and restored platinum sensitivity in vitro and in vivo Overall, our results define the pathogenic characters of a cancer stem-like subpopulation in lung cancer, the targeting of which may relieve platinum resistance in this disease.

Abstract
BACKGROUND AND AIMS We aimed to evaluate the association between famine exposure during early life and obesity and obesitymax (obese at the highest weight) in adulthood. METHODS AND RESULTS Data were from two population-based cross-sectional surveys conducted in 2006 and 2009 in Qingdao, China. A total of 8185 subjects born between 1/1/1941 and 12/31/1971 were categorized into unexposed (born between 01/01/1962 and 12/31/1971), fetal/infant exposed (born between 01/01/1959 and 12/31/1961), childhood exposed (born between 01/01/1949 and 12/31/1958) and adolescence exposed (born between 01/01/1941 and 12/31/1948) according to their age when exposed to the Chinese famine from 1959 to 1961. Obesity was defined as BMI (body mass index) ≥28.0 and obesitymax was defined as BMImax (BMI at the highest weight) ≥28.0. We compared fetal/infant exposed, childhood exposed and adolescence exposed to the unexposed using logistic regression models to assess the effect of famine exposure on later obesity and obesitymax. Fetal/infant exposed (OR = 1.59, P < 0.001), childhood exposed (OR = 1.42, P < 0.01) and adolescence exposed (OR = 1.86, P < 0.01) all had higher risks of obesity than the unexposed. Exposure groups were more likely to be obese at their highest weight than the unexposed, and ORs (95%CIs) for obesitymax in the fetal/infant exposed, childhood exposed and adolescence exposed were 1.49(1.20-1.86), 1.24(1.02-1.49) and 1.64 (1.40-1.93), respectively. Similar results were found in both men and women. CONCLUSION Exposure to famine in early life was associated with increased risks of obesity and obesitymax in adulthood. Preventing undernutrition in early life appears beneficial to reduce the prevalence of later obesity.

Abstract
AIMS To study the cardiovascular disease risk profiles in newly diagnosed diabetes diagnosed by either glucose or/and HbA(1c) criteria in Chinese adults. METHODS Two population-based cross-sectional studies were conducted in 2006 and 2009, respectively. Data from 1987 men and 2815 women aged 35-74 years were analysed. Newly diagnosed diabetes was defined according to either glucose (fasting and/or 2-h glucose), HbA(1c) or both criteria. RESULTS Ageing, positive family history of diabetes, elevated levels of waist circumference, systolic blood pressure, total cholesterol, triglycerides and γ-glutamyl transferase were independently associated with newly diagnosed diabetes defined by glucose criterion alone, but not for diabetes defined by HbA(1c) criterion alone. Only waist circumference, total cholesterol and smoking were significantly associated with the presence of diabetes defined by HbA(1c) criterion alone. CONCLUSIONS Cardiovascular disease risk profiles were different in patients with newly diagnosed diabetes defined by the two diagnostic criteria for diabetes. This may have certain clinical implications on diabetes management and research.

Abstract
AIMS To evaluate costs and effectiveness of implementing a diabetes self-risk assessment (Diabetes Risk Score) questionnaire coupled with a multimedia health promotion campaign on changes in diabetes awareness in a large diabetes prevention programme. METHODS Between 2007 and 2010, a multimedia health promotion campaign was conducted targeting the 1.94 million population of Qingdao, China, using newspapers, radio programmes, distribution of free booklets and Diabetes Risk Score flyers. Diabetes awareness questionnaires filled out by people first interviewed in 2006 (survey A), before the initiation of the campaign, were compared with those first interviewed between 2007 and 2010 during the campaign period (survey B). The rates of diabetes awareness in both surveys were studied amongst adults aged 35-74 years without a prior history of diabetes, but with a Diabetes Risk Score of ≥ 14. RESULTS In survey B, 85, 82 and 76% of the urban participants correctly recognized obesity, family history of diabetes and physical inactivity, respectively, as important risk factors for diabetes; while the awareness rates were 43, 46 and 25%, respectively, in survey A (P < 0.001). The corresponding figures among rural participants were 65, 63 and 53% in survey B and 29, 22 and 11% in survey A (P < 0.001). To cover 1000 individuals, the programme spent €5.4 on the use of the Diabetes Risk Score flyer, €31.3 on the education booklet, €7.7 on the newspaper campaign and €37.5 on radio programmes. CONCLUSIONS The combination of a Diabetes Risk Score questionnaire with a multimedia health promotion campaign is a cheap and effective health promotion tool to raise public awareness of diabetes.

Abstract
AIMS To investigate the prevalence of metabolic syndrome and its components in both rural and urban Chinese population. SUBJECTS AND METHODS A population-based crosssectional survey was conducted in Qingdao, China in 2006 with 6100 Chinese aged 35-74 yr invited and 5355 who attended; 3357 subjects, 1562 urban (46.5%) and 1795 rural residents (53.5%) met the inclusion criteria for the current data analysis. The metabolic syndrome definitions of National Cholesterol Education Program Adult Treatment Expert Panel III (NCEPATPIII) 2004, NCEP 2005 and International Diabetes Federation (IDF) were used. RESULTS The age-standardized prevalences of metabolic syndrome were 16.2%, 32.2%, and 28.3% in men and 26.8%, 37.2%, and 34.6%in women, according to the definitions of the NCEP 2004, NCEP 2005, and IDF, respectively. Urban men have more risk factors and higher prevalence of the metabolic syndrome than rural men, but the differences in women were not that striking. Elevated blood pressure (62.6%) was, among risk factors, most common in the study population, followed by central obesity (53.4%), and hyperglycemia (52.2%) defined using the NCEP 2005 criteria. CONCLUSIONS Metabolic disorders were common among adult Chinese in both rural and urban areas in Qingdao.

Abstract
CONCLUSION This study shows that cochlear implantation is relatively safe surgery with few major complications and within acceptable limits. However, close follow-up observation and effective medical and nursing intervention could alleviate further complications and thus become key elements for promoting recovery of patients undergoing such surgery. OBJECTIVES Cochlear implantation has become an effective method for curing patients disabled by profound hearing loss in China. However, full exploration of the associated complications remains to be completed. The objective of this study was thus to analyse the postoperative complications in patients with cochlear implants (CIs) in order to design improved measures for clinical and nursing interventions. METHODS A retrospective study of 262 patients receiving CIs at the Department of Otorhinolaryngology/Head and Neck Surgery, Chinese People's Liberation Army General Hospital, Beijing, China from March 1997 to December 2006 was conducted. RESULTS Among 262 patients, 4 cases (1.5%) had 1 or more major complications requiring substantial medical or nursing interventions, including 1 case of cerebrospinal fluid (CSF) otorrhoea accompanied by meningitis, 2 cases of facial nerve paresis and 1 case of perforation of tympanic membrane. Forty cases (15.3%) had some form of minor complication that settled spontaneously or easily with conventional treatments and nursing, of which dizziness and vomiting was the most frequent (4.2%), followed by CSF gusher without otorrhoea and/or induced meningitis (2.7%), tinnitus (1.9%) and facial nerve partially exposed without paralysis (1.5%). Eleven cases (4.2%) had some symptoms associated with installation of the cochlear device. Except for one patient who had no response after implantation because his auditory nerves were underdeveloped, all the patients who received appropriate treatment and nursing intervention had a favourable prognosis.

Abstract
BACKGROUND Age is associated with both impaired glucose and insulin metabolism. To what extent the age-related changes in insulin resistance (IR) and beta-cell function contribute to the increase in prevalence of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) is less known, and this is investigated in this study. METHODS This study included 6610 men and 7664 women of different ethnic groups aged 30-69 years. IR and beta-cell function were examined by the homeostasis model assessment of insulin resistance (HOMA-IR) and homeostasis model assessment of beta-cell function (HOMA-B). Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated using logistic regression analysis adjusting for body mass index and study. RESULTS In Chinese men, the ORs (95% CIs) for IFG were 2.69 (1.70, 4.26), 2.51 (1.49, 4.21) and 2.89 (1.68, 4.97), respectively, in age groups of 40-49, 50-59 and 60-69 years compared with 30-39 years (p < 0.001 for trend); the corresponding figures for IGT were 1.73 (1.25, 2.38), 2.54 (1.78, 3.63) and 3.57 (2.46, 5.19) (p < 0.001 for trend). Similar trends for IGT were observed also in Chinese women and other ethnic groups, but not for IFG in Mauritius Indian and Creole men. Adjustment for HOMA-IR and HOMA-B reduced the ORs in all age groups of all ethnicities for both IFG and IGT, but the risk gradient between age groups remained particularly for the IGT. CONCLUSIONS The age-related increase in glucose intolerance may not be fully explained by the defect in HOMA-IR and HOMA-B. As HOMA-IR and HOMA-B are only surrogate measures of insulin sensitivity and insulin secretion, the results need to be further investigated.

Abstract
AIMS To determine the secular trend of prevalence of Type 2 diabetes and pre-diabetes in a Chinese population from 2001 to 2006. METHODS Two consecutive population-based surveys for diabetes were conducted in a randomly selected population aged 35-74 years and living in Qingdao, China in 2001-2002 (n = 10854) and 2006 (n = 4416). All participants underwent standardized 2-h 75-g oral glucose tolerance tests (OGTTs), along with fasting capillary plasma glucose (FCG) tests in 2006. One urban community underwent OGTTs directly in 2002 (n = 1815), while a two-step screening strategy using FCG as a first-line screening test followed by OGTTs was used in 9039 individuals in 2001. Diabetes and pre-diabetes was defined according to the 2006 World Health Organization/International Diabetes Federation criteria. RESULTS Based on the results of direct OGTTs, the age-standardized prevalence of diabetes and pre-diabetes in urban areas was 12.2 and 15.4% in 2002, whereas the prevalences were 18.8 and 28.7% in urban areas and 14.1 and 20.2% in rural areas in 2006 (P < 0.001, in urban areas). Using the two-step screening strategy, the prevalence of diabetes in 2001 was 10.1% in urban and 7.7% in rural areas and 13.8% in urban and 12.2% in rural areas in 2006 (P < 0.001). Based on the data of the 2006 survey, the two-step screening strategy missed 30.2% of diabetes cases when compared with the number defined by the direct OGTT approach. CONCLUSIONS Qingdao has experienced a marked increase in the prevalence of diabetes and pre-diabetes in the past 5 years. Intervention to prevent a further increase in the prevalence of diabetes is urgently required.

Abstract
OBJECTIVE To investigate the major risk factors and their association with the dramatic increase in the prevalence of diabetes from 2001-2002 to 2006 in Qingdao, China. METHODS Population-based cross-sectional studies on diabetes were performed in 4598 men and 7026 women aged 35-74 years. The 2006 World Health Organization diagnostic criteria for diabetes were used. RESULTS The crude prevalence of diabetes was 11.3% in both men and women in urban areas and 5.3% and 8.9% in rural areas in 2001-2002. This increased to 19.2% and 16.1% in urban areas and 14.2% and 13.8% in rural areas in 2006 for men and women, respectively. The increase in diabetes prevalence from 2001-2002 to 2006 was paralleled by an increased body mass index in rural areas but not in urban areas. The major risk factors associated with diabetes were age, family history of diabetes, obesity, hypertension and high triglycerides. The multivariate adjusted odds ratio and 95% confidence interval for diabetes corresponding to a one standard deviation increase in waist circumference was 1.81 (1.47, 2.23) in urban men, 1.64 (1.26, 2.13) in rural men, 1.98 (1.66, 2.37) in urban women and 2.02 (1.63, 2.51) in rural women. Low socio-economic classes had a higher risk for diabetes in urban areas but a lower risk in rural areas, both associated with increased waist circumference. CONCLUSION Established risk factors are of great importance for the prevalence of diabetes in the urban and rural Chinese populations and changes in these factors could explain the recent dramatic increase in diabetes prevalence, particularly in rural areas. Considering the high prevalence of obesity and physical inactivity, intervention is urgently required in China.

Abstract
This study was to observe the result in patients suffering from severe ischemia of legs with arterialization of the great saphenous vein. Eighty nine patients suffering from the disease were treated by bridging the autogenous cephalic vein or Gore-Tex artificial vessel between the great saphenous vein and the femoral or external iliac arteries. The results showed that the blood supply of the affected legs was increased immediately after operation. The ulcers of the toes and the plantar areas were healed gradually and the pain relieved. It was concluded that this method did not interfere with the reflux of the venous blood in the diseased limbs. This method was simple, safe and effective for treating severe ischemia of the lower limbs.
