Abstract
BACKGROUND Gallbladder torsion is a rare acute abdominal condition that requires emergency surgery. It occurs more commonly in elderly people and in women in the adult population. Diagnosis is a challenge as non-specific symptoms and signs have been reported on ultrasonography, computed tomography and magnetic resonance imaging. Prompt cholecystectomy can decrease the mortality and morbidity of perforation due to gallbladder torsion.
CASE SUMMARY An 82-year-old woman with upper-right quadrant pain and associated nausea and vomiting was diagnosed with ectopic acute calculus cholecystitis. Magnetic resonance cholangiopancreatography (MRCP) showed a V-shaped distortion of the extrahepatic bile ducts and a particularly extended twisted cystic duct, which indicated the presence of gallbladder torsion. Emergency laparoscopic cholecystectomy confirmed the diagnosis and the patient recovered without incident.
CONCLUSION Gallbladder torsion can be diagnosed pre-operatively by MRCP. The specific signs are a V-shaped distortion of the extrahepatic bile ducts and a particularly extended twisted cystic duct which can be called twisting signs.

Abstract
A novel, compact, TM01-TE10 mode power divider and a novel, compact, four-way TE10-TM01 mode power combiner were theoretically designed and experimentally tested as a proof of principle. The theoretical and experimental S parameters are consistent with each other. High-power experiments show that their power capacities are no less than 1.5 GW and 3 GW, respectively. The devices have the merits of high power capacities and low insertion losses.

Abstract
INTRODUCTION The Candida albicansTHI13 gene was identified by its homology to the Candida tropicalis CtNMT1 gene, which is involved in pyrimidine precursor biosynthesis. METHODS Disruption of THI13 revealed that this gene played a minor role in thiamin biosynthesis in C. albicans. Purified human monocytes were incubated with C. albicans at the optimal Candida: monocyte ratio of 0.5 and cytokines in the supernatants were measured by enzyme-linked immunosorbent assay. RESULTS AND DISCUSSION This experiment showed that the wild-type strain significantly induced interleukin-10 (IL-10) production but had little effect on IL-12 production, and that THI13 mutants had no significant effect on IL-10 production, though the IL-12 level was increased in the supernatants. These results suggest that THI13 is involved in the host effective immune response by regulating IL-10 and IL-12 production.

Abstract
The author of this article visited China for the purpose of helping the faculty of the School of Nursing learn research skills by participating in research--a kind of learn by doing. Both investigators had conducted quantitative studies in the US--one with children and one with adults--that were adapted for use in China. Seeking to also include a qualitative study, the investigators explored several possible research areas. Because pain is a universal phenomena, it was chosen as the subject for the study using the qualitative methodology reported in the first part of this article.

Abstract
The present paper deals with a microwave plasma torch atomic emission detector for gas chromatography. Argon is used as support gas, carrier gas and make-up gas. The effect of oxygen scavenger gas on the detection performance for chlorine, bromine and iodine is discussed. Detection limits, dynamic ranges, relative standard deviations and response characteristics of GC-MPT-AED for chlorine, bromine and iodine in organic compounds were studied. The results are favorable in comparing with GC-ICP-AED.

Abstract
35 healthy and hybrid dogs were divided into the control group (5 dogs), ischemic group (15 dogs) and medicated group (15 dogs). The myocardial ischemia model was produced by ligating the left coronary artery between the branch 2 and 3 among the anterior descending branches. The effect of the herbs on the experimental myocardial ischemia was observed by measuring the Mean Artery Pressure (MAP), the Left Ventricular End Diastolic Pressure (LVEDP), the Heart Rate (HR), the Cardiac Output (CO) and the Cardiac Index (CI) etc. The results showed that the LVEDP was significantly increased and the MAP, the CO and the CI were lowered during the period of myocardial ischemia, which indicated the disorder of cardiac heaemodynamics after the myocardial ischemia, By taking the medicine through the duodenum in the medicated group, the CO was obviously increased during the period of myocardial ischemia and also the CI was elevated prominently. The investigation indicated that the medicine could reinforce the cardiac pump function and adjust the disorder of cardiac haemodynamics resulted from myocardial ischemia.
