ObjectiveTo explore the effect of personality and psychosocial factors on irritable bowel syndrome (IBS).MethodsPersonality and psychological status of 46 IBS patients and 32 healthy individuals were evaluated with Eysenck Personality Questionaire (EPQ), Symptom Checklist-90 (SCL-90) and Life Events Scale (LES).ResultsIn EPQ, E (extroversion-introversion) scores of IBS group were lower than those of control group; N (neuroticism) scores of IBS group were significantly higher than those of control group (P<0.01). In SCL-90, the scores of somatization, compulsion, anxiety, depression and etc. were higher than those of control group (P<0.05). The frequency of meeting negative life events, the quantity of stimulus of meeting negative life events and the total quantity of stimulus of meeting life events of IBS patients within one year until episode were significantly higher than those of control group (P<0.01).ConclusionPersonality psychological characteristics and life events before illness are associated with the morbidity of IBS.

Receptor of activated C-kinase 1 (RACK1) shows different expression in various tumors,because its seven WD repeating sequences can combine with a variety of molecules.In addition to activating protein kinases C,RACK1 still plays a role in many tumor-related signaling pathways.With the deepening of research,RACK1 is expected to play an active role in cancer diagnosis,treatment and prognosis.

BackgroundBoth accommodative abnormality and higher order wavefront aberrations associated with near work are interrelated with blurry retinal image.It is very important to investigate the higher order wavefront aberrations in stable and progressive myopic eyes before and after near work. ObjectiveThe present study wasto observe the high order aberration change of myopic eyes before and after computer work upon near work stimulation as well as the relationship of high order aberration changes to types of myopia. MethodsThe case-controlled design was used in this clinical study.Sixty right eyes of 60 subjects were enrolled,including 30 progressive myopias and 30 stable myopias with matched age and gender.Refractive errors of the subjects were completely corrected by the wearing of spectacles.The subjects remained the work for 1 hour in front of a computer monitor with 40 cm distance under the dark environment and nature pupil size,and the height of the eye and monitor center kept the same level.The changes of wavefront aberration in test eyes were measured with Complete Ophthalmic Analysis System before and after 1 hour of continuous computer work.The influences of computer-work and myopia types on wavefront aberration were analyzed in 3,4,5 mm pupil size.Root-mean-square (RMS) of aberrations was calculated as the index of higher order wavefront aberrations.ResultsThere were no significant differences in the higher order wavefront aberrations before and after computer work for the two types of myopic eyes under the 3,4,5 mm pupil.The RMS of higher order wavefront aberrations were similar between progressive myopia and stable myopia under the 3 mm pupil condition.Total higher order RMS,6th-order,5th-order and 3rd-order RMS were significantly higher in progressive myopic group compared with stable myopic group under the 4 mm pupil size ( RMS3:F =5.985,P =0.016 ; RMS5:F =3.975,p=0.049;RMS6:F=8.130,P=0.005:RMST:F=6.493,P=0.012) and 5mm pupil size(RMS3:F=13.132,P=0.000;RMS5:F =4.032,P=0.047 ; RMS6:F =4.393,P=0.038:RMST:F=10.508,P=0.002 ).The spherical aberrations were higher in progressive myopic group under the 3,4,5 mm pupil conditions in comparison with stable myopic group,but these alterations were insignificant between two types of myopias ( P>0.05 ).Conclusions Higher order wavefront aberrations of progressive myopic eyes is comparable higher than the stable myopic eyes.Computer reading task dose not significantly impact the higher order wavefront aberrations on myopic eyes.

Objective To evaluate the clinical efficacy of ureteroscopy for the diagnosis and treatment of renal colic. Methods A total of 50 cases of renal colic were diagnosed and treated by ureteroscopy. Stones with size smaller than 0 5 cm were removed, but lithoclasty was performed on those stones with size bigger than 0 5 cm. In addition, J shaped catheters or ureteral catheters were indwelt for drainage. Results Successful removal of stones and lithoclasty were achieved in 12 and 30 cases, respectively. No urolithiasis and other lesions were found in 3 cases. Improvement was found in those cases with indwelt catheters. The average stay was 4-5 d. Correlative etiological factors were found in 2 patients by ureteroscopy. Conclusion Transurethral ureteroscopy is an effective and safe method for the diagnosis and treatment of renal colic.

Objective To evaluate the clinical efficacy of ureteroscopy for the treatment of acute renal failure caused by ureteric obstruction. Methods A total of 28 cases of acute renal failure caused by ureteric obstruction were treated with ureteroscopy combined with pneumatic lithotriptor, holmium YAG laser, and ESWL. Results Renal function and urine volume of patients return to normal after treatment, while the stone free rate was up to 92.9% (26/28). Conclusion Ureteroscopy is a new, efficient, and safe method for the treatment of acute renal failure induced by ureteric obstruction.

Chronic low back pain is a common type of pain which is related to the dysfunction of low back muscles. In recent years, the pressure biofeedback has been widely used for the assessment and treatment of chronic low back pain. This paper reviewed the reliability and validity of pressure biofeedback unit in the evaluation of lumbar and abdominal muscles activity, as well as its application on the rehabil-itation of chronic low back pain, which mainly related to the assessment and treatment of lumbar muscle activity and lumbar spine stability.

BACKGROUND: Protein drugs such as insulin are usually used in the form of injection due to its low oral administration bioavailability. For the purpose of higher bioavailability, the common method is to encapsulate the drug into algitnate/chitosan microspheres, which introduced polysaccharides to accelerate biological absorption or reduce demolition of protease. OBJECTIVE: To construct alginate/chitosan microspheres containing cationic?-cyclodextrin polymer (CP?CD) /insulin complex for insulin oral delivery system, in addition, to inspect the influence of the charge density of cationic ?-cyclodextrin polymers on insulin release performance in vitro. DESIGN, TIME AND SETTING: The contrast observation experiment was performed at the Laboratory of Department of Polymer Science and Engineering, Sichuan University from November 2006 to July 2008. MATERIALS: ?-cyclodextrin, epichlorohydrin was supplied by Tianjin Bodi Chemical Industry Co., Ltd. Choline chloride and alginate was provided by Kelong Reagent Company, chitosan was purchased from Golden-shell Biochemical Co., Ltd. And insulin was produced by Wanbang Biochemical Pharmaceutical Company. METHODS: Cationic ?-cyclodextrin polymer was synthesized through a one-step polymerization of ?-cyclodextrin, epichlorohydrin and choline chloride. It was combined with insulin and then encapsulated into alginate/chitosan microspheres. In vitro insulin release behavior of the microsphere was studied in simulative gastrointestinal fluid. MAIN OUTCOME MEASURES: The entrapment efficiency, as well as insulin release in simulative gastrointestinal fluid. RESULTS: The charge density of CP?CD had a great impact on the insulin association efficiency of microspheres. The maximum association efficiency could reach (76.3?1.5)%. It showed that cumulative insulin release of microspheres containing CP?CD was less than that of the control group in simulated gastric fluid. The insulin released was 5.8 IU in simulated intestinal fluid, which was higher than the control group. CONCLUSION: Alginate/chitosan microsphere containing CP?CD/insulin complex is a promising system for improving insulin oral delivery efficiency.
