A Computer-aided Production System for Mass Customization in Fashion
In order to meet the demands of the market, a computer-aided production system for mass customization in fashion is proposed. The system enables the automation of dimension collection, pattern generation and fabric cutting. By integrating the system with the processes of garment sewing, fitting test and final adjustment, mass customization can be realized in the apparel industry. For the manufacturers, the efficiency of the supply chain can be improved by reducing human efforts, costs, and production time. For the customers, better fitness with faster delivery stimulates the desire of purchase and enhances their satisfaction.
Coal spontaneous combustion is an extremely complicated physical and chemical changing process. In order to improve the indicator gases detection technology and coal spontaneous combustion monitoring, a novel forecast method for toxic gases emission from coal oxidation at low temperature is presented in this paper. The experiment system is setup combined with frequency-domain terahertz technology and coal temperature programming device. The concentration curves of carbon monoxide and sulphur dioxide gases from coal spontaneous combustion are estimated according to molecule terahertz spectra. The influences of coal rank and oxygen supply on coal spontaneous combustion characteristics are discussed. Both carbon monoxide and sulphur dioxide gases absorption spectra show the characteristic equi-spaced absorption peaks. Results demonstrate that under the condition of lean oxygen, there exists a critical oxygen concentration in the process of coal oxidation at low temperature. Comparing with Fourier infrared spectrum testing, the presented method is highly accurate and more sensitive, especially suitable for early-stage monitoring of the indicator gases produced by coal spontaneous combustion.
Hemorrhagic fever with renal syndrome (HFRS) is caused by hantavirus infection, which was characterized by abrupt high fever, systemic hemorrhage, hypotension and renal damage. Although multiple system organ damage was not uncommon, but multiple organ system failure were rare. Hereafter we report one case with simultaneous renal, heart and liver failure. In this case, we received some experience and lessons.
The small Southeast Asian ruteline genus Glenopopillia Lin, 1980 is revised. We describe four new species: Glenopopillia albopilosa Zorn & Lu sp. nov. from Vietnam, Glenopopillia forceps Zorn & Lu sp. nov. from India, Glenopopillia mengi Lu & Zorn sp. nov. from China and Laos, and Glenopopillia skalei Zorn & Lu sp. nov. from Vietnam; and one new subspecies: Glenopopillia rufipennis nigropicta Zorn & Lu subsp. nov. from Laos; propose two new combinations: Glenopopillia fossulata (Benderitter, 1929) comb. nov. (from Strigoderma fossulata Benderitter, 1929) and Glenopopillia klossi (Ohaus, 1926) comb. nov. (from Spilota klossi Ohaus, 1926), bringing the total number of species group taxa in this genus to ten. We characterize the genus, provide a key to the species, describe and diagnose each species group taxon, and compile a distribution map. A lectotype for Spilota klossi Ohaus, 1926 is designated.
Objective A diagnostic model was established to discriminate infectious diseases from non-infectious diseases.
Methods The clinical data of patients with fever of unknown origin (FUO) hospitalized in Xiangya Hospital Central South University, from January, 2006 to April, 2011 were retrospectively analyzed. Patients enrolled were divided into two groups. The first group was used to develop a diagnostic model: independent variables were recorded and considered in a logistic regression analysis to identify infectious and non-infectious diseases (αin = 0.05, αout = 0.10). The second group was used to evaluate the diagnostic model and make ROC analysis.
Results The diagnostic rate of 143 patients in the first group was 87.4%, the diagnosis included infectious disease (52.4%), connective tissue diseases (16.8%), neoplastic disease (16.1%) and miscellaneous (2.1%). The diagnostic rate of 168 patients in the second group was 88.4%, and the diagnosis was similar to the first group. Logistic regression analysis showed that decreased white blood cell count (WBC < 4.0×109/L), higher lactate dehydrogenase level (LDH > 320 U/L) and lymphadenectasis were independent risk factors associated with non-infectious diseases. The odds ratios were 14.74, 5.84 and 5.11 (P ≤ 0.01) , respectively. In ROC analysis, the sensitivity and specificity of the positive predictive values was 62.1% and 89.1%, respectively, while that of negative predicting values were 75% and 81.7%, respectively (AUC = 0.76, P = 0.00).
Conclusions The combination of WBC < 4.0×109/L, LDH > 320 U/L and lymphadenectasis may be useful in discriminating infectious diseases from non-infectious diseases in patients hospitalized as FUO.
Background: Coronary artery bypass grafting (CABG) is an effective method to afford sufficient blood flow for that ischemic myocardium. Off-pump coronary bypass surgery (OPCAB) has been rediscovered and refined to avoid cardiopulmonary bypass. However, it’s a high technique demanding skill. And evaluation of the blood flow should be reliable. Transit time flow measurement (TTFM) is introduced to evaluate graft flow and anastomosis patency intraoperatively. The accuracy of graft flow depends on how to explain the parameters of TTFM. Here, we introduce our experiences on the explanation of TTFM parameters.
Objective: We compared the graft patency of off-pump coronary artery bypass grafting with those of on-pump coronary artery bypass grafting by intraoperative transit time flow measurement (TTFM).
Methods: Three hundred patients were divided into off-pump group and on-pump group. TTFM was routinely performed for assessment of graft patency during operation. Revision of the grafts depends on the TTFM findings.
Results: One patient in OPCAB group was converted to conventional CABG group due to ventricular fibrillation. One patient died of multiple organ failure 21 days post-operation. Seven grafts were revised based on unsatisfactory TTFM findings. There was no statistical difference in the variables between the two groups except for anastmosis to right coronary artery.
Conclusions: Off-pump surgery can provide the same flow of grafts as that of on-pump surgery. TTFM is an effective tool to decide if a well-function graft is or not, and it allows for revision of failure graft during operation.
The prevalence and microbial pattern reported for Community-acquired pneumonia (CAP) differ considerably and contemporary situation remains changing over time. We therefore searched both international and domestic databases for relevant references and pooled incidence of CAP and etiological distribution were estimated separately between children and adults groups. The results showed that CAP remained a major public health issue in China, with a relatively higher incidence than that reported in Western countries. Although pathogens were not detected in nearly half of patients, Mycoplasma pneumoniae remained to be the most frequently detected agent across age groups, the detection yield of which was lower than that reported from other countries. Notably, the incidence of influenza virus A in adults was almost four times higher than that in children while the prevalence of respiratory syncytial virus was much less common in adults than that in children. Despite some limitations, the value of this review, approaching to systematically review grey published data, is to sketch out the contemporary epidemiological and etiological situation of CAP in our country, which could be useful to help policymakers and clinicians make informed choices and to inspire future studies and surveillance.
There is little information focusing on the nutritional issue of pediatric recipients before they receive living donor liver transplantation. This study illustrates the relationship between nutritional status and graft liver function and provides a reference regarding nutritional interventions in future studies.
We prospectively collected data from 30 pediatric living donor liver transplant recipients from January 1, 2016, to June 30, 2016. The information included demographic data, preoperative nutritional assessment, and postoperative laboratory examinations. The nutritional assessment included the serum concentration of vitamin D, bone density, trace element, and weight Z value. The laboratory examinations included white blood cell count, neutrophil percentage, hemoglobin, blood platelet, total protein, albumin, total bilirubin, direct bilirubin, alanine transaminase, aspartate aminotransferase (AST), alkaline phosphatase, gamma-glutamyl transpeptidase, creatinine, bile acid, blood glucose (Glu), prothrombin time, international normalized ratio, tacrolimus concentration, and graft-to-recipient weight ratio (GRWR). The data were collected on Days 1, 2, 3, 4, 5, 6, 7, 14, 30, and 60 after liver transplantation.
The recipients consisted of 15 (50%) males and 15 (50%) females. The median age was 7 months (4–48 months). The mean height and weight were 69.07±9.98 cm and 8.09±2.63 kg, respectively. According to the univariate analysis, the gender, diagnosis, blood type, and GRWR did not significantly impact the liver function after the operation. The posttransplantation AST levels and Glu showed significant differences in terms of the nutritional status, with P<0.05. The multivariate correlation analysis showed that the serum concentrations of vitamin D and AST were midrange positively correlated, with P<0.05.
The nutritional status of patients with biliary atresia is relatively poor. There is a definite midrange positive correlation between nutrition and graft liver function that might play a relatively important role in the recovery of the graft.
Background: Spinal cord injury severely impairs fertility of young men. It can induce erectile dysfunction, ejaculatory dysfunction, and semen abnormalities. However, the precise mechanism is unclear.
Objective: We observed the effects of sacral nerve electrostimulation on sex dysfunction of male rats with spinal cord injury.
Methods: Thirty-six male Sprague-Dawley (SD) rats were randomly divided into three groups (n = 12): sham operated group, spinal cord injury model group, and electrostimulation group. The weight of genitals, related sex hormone index, and sperm motility were examined in each group after operation at two, four, and six weeks, respectively.
Results: Sacral nerve electrostimulation could improve testis and epididymis weight, regulate hormone secretion (including an increase in GnRH, tT, and ABP, but decrease in FSH and LH), and cause an increase in sperm count and motility.
Conclusion: Sacral nerve electrostimulation may be effective in treating sex dysfunction resulting from spinal cord injury.
