Background:The association between non-obese or lean nonalcoholic fatty liver disease(NAFLD)and gallbladder polyps(GBPs)has not yet been *** aimed to determine whether NAFLD is an independent risk factor for the development of GBPs,even in non-obese and lean ***:We analyzed a cohort of 331208 asymptomatic adults who underwent abdominal ultrasonography(US).The risk of GBP development was evaluated according to the obesity and NAFLD ***:The overall prevalence of NAFLD and GBPs≥5 mm was 28.5%and 2.9%,*** prevalence of NAFLD among 160276 lean,77676 overweight and 93256 obese participants was 8.2%,31.2%,and 61.1%,*** with NAFLD had a significantly higher incidence of GBPs with a size of≥5 mm[adjusted odds ratio(OR)=1.18;95%confidence interval(CI):1.11–1.25].A higher body mass index and its categories were also significantly associated with an increased risk of GBPs≥5 ***,risk of GBPs≥5 mm was significantly increased even in NAFLD individuals who are not obese(lean:adjusted OR=1.36,95%CI:1.19-1.54;overweight:adjusted OR=1.14,95%CI:1.03–1.26,respectively).Conclusions:Non-obese/lean NAFLD is an independent risk factor for GBP development,suggesting that NAFLD may play an important role in the pathogenesis of GBPs regardless of the obesity ***,a more thorough evaluation for GBPs may be necessary when hepatic steatosis is detected on abdominal US,even in non-obese or lean individuals.

From the medical history of traditional Eastern Asian and Tibetan medicine, the origin and development of moxibustion seems to be closely related to Mongolia. To explore the current clinical practice of moxibustion in Mongolia, we visited a teaching hospital, the Traditional Medical Science, Technology and Production Corporation of Mongolia, in February 2014. Many types of moxibustion are found to be used, and various modalities and methods are practiced based on the principles of traditional Mongolian medicine. In particular, Mongolian drug moxibustion, which uses small butter-warmed bags packed with powdered aromatic herbs instead of moxa cones, is a unique moxibustion technique not found in other countries. In this paper, we introduce the clinical practice of moxibustion, specifically Mongolian drug moxibustion in Mongolia.

Large-capacity compressors in industrial plants and the compressors in gas turbine engines consume a considerable amount of power. The compression work is a strong fimction of the ambient air temperature. This increase in compression work presents a significant problem to utilities, generators and power producers when electric demands are high during the hot months. In many petrochemical process industries and gas turbine engines, the in- crease in compression work curtails plant output, demanding more electric power to drive the system. One way to counter this problem is to directly cool the inlet air. Inlet fogging is a popular means of cooling the inlet air to air compressors. In the present study, experiments have been performed to investigate the suitability of two-fluid nozzle for inlet fogging. Compressed air is used as the driving working gas for two-fluid nozzle and water at am- bient conditions is dragged into the high-speed air jet, thus enabling the entrained water to be atomized in a very short distance from the exit of the two-fluid nozzle. The air supply pressure is varied between 2.0 and 5.0 bar and the water flow rate entrained is measured. The flow visualization and temperature and relative humidity measurements are carried out to specify the fogging characteristics of the two-fluid nozzle.

An 87-year-old male with old myocardial infarction was referred to the hospital due to left femur neck fracture and intermittent dizziness. Significant 2:1 atrioventricular block was demonstrated on initial electrocardiogram (Figure 1). Transthoracic echocardiography showed reduced left ventricular function (LVEF = 47%) with regional wall motion abnormality of right coronary artery (RCA) and left circumflex coronary artery (LCx) artery. Coronary angiography showed patent previous proximal RCA and distal LCx stents. Temporary pacemaker was inserted initially and the patient was planned for permanent pacemaker insertion after the surgery.

Evaluating the expected sliding distance of a vertical slit caisson breakwater is proposed. Time history for the wave load to a vertical slit caisson is made. It consists of two impulsive wave pressures followed by a smooth sinusoidal pressure. In the numerical analysis, the sliding distance for an attack of single wave was shown and the expected sliding distance during 50 years was also presented. Those results were compared with a vertical front caisson breakwater without slit. It was concluded that the sliding distance of a vertical slit caisson may be over-estimated if the wave pressure on the caisson is evaluated without considering vertical slit.

This study comprises a systematic review and meta-analysis of micmsurgical vasoepididymostomy outcomes in epididymal obstructive azoospermia.A comprehensive literature search was performed using Medline,Embase,and the Cochrane library that included all studies related to microsurgical *** included “vasoepididymostomy,”“epididymovasostomy,”“epididymal obstruction,”and “epididymis obstruction.”Event rate and risk ratio (RR)were *** rate and pregnancy rate were *** analysis comprised 1422 articles,including 42 observational studies with 2298 enrolled patients performed from November 1978 to January *** overall mean patency rate was 64.1%(95%confidence interval [CI]:58.5%-69.3%;F=83.0%),and the overall mean pregnancy rate was 31.1%(95%CI:26.9%-35.7%;I^2=73.0%).We performed a meta-analysis comparing the patency rate of bilateral microsurgical vasoepididymostomy and unilateral microsurgical vasoepididymostomy and found an RR of 1.38%(95%CI: 1.21%-1.57%;P <0.00001).A comparison of the site of microsurgical vasoepididymostomy showed that caudal or corpus area was favorable for patency rate (RR =1.17%;95%CI: 1.01%-1.35%;P =0.04).Patients with motile sperm in epididymal fluid exhibited an RR of 1.53%(95%CI:1.11%-2.13%;P =0.01)with respect to patency rate. Microsurgical vasoepididymostomy is an effective treatment for epididymal obstructive azoospermia that can improve male fertility. We find that performing microsurgical vasoepididymostomy bilaterally,anastomosing a larger caudal area,and containing motile sperm in epididymis fluid can potentially achieve a superior patency rate.

A 39-year-old male patient complaining of bilateral hand joint arthralgia was evaluated and found to have chronic hepatitis C and systemic sarcoidosis involving lung, skin, liver, and spleen. Hepatic and cutaneous sarcoidoses were confirmed by the presence of numerous noncaseating granulomas on histological examination. Pulmonary and splenic involvements were diagnosed by imaging studies. Fifteen months later, the sarcoidotic lesions in lung, liver, and spleen were resolved by radiological studies and a liver biopsy showed no granuloma but moderate to severe inflammatory activity, systemic sarcoidosis is a rare comorbidity of chronic hepatitis C which may spontaneously resolve.
