Objective support score, the use score for social support and sensation seeking score can forecast the internet addiction extent of the internet addict group. Internet addicts have obviously lower L score of EPQ than non-addicts ( P<0.01 ). There is the negative correlation between N score of the internet addicts and sensation seeking score( r=-0. 452, P<0.05). Conclusions Serious internet game addicts have the metal characteristics of low social support, low purpose in life and low adventure; sensation seeking and social support scale have prognosticative function for internet addiction degree; serious internet game addicts of low N score have high sensation seeking characteristic.

Sepsis is one of the serious illnesses leading to high mortality in ICU.Some animal experiments and clinical trails show that target temperature management has a protective effect on target organ function in sepsis,but the optimal timing,length of targeted temperature managment continued,intervention measures,and optimal target temperature obtained in sepsis remains in the great controversy.Whether the patients with sepsis would be truly benefited from the body temperature management is still worthy issue for further study.The aim of this article reviews is to trace the recent research progress on the body temperature management in sepsis.

ObjectiveTo establish a method for rapid identification of bloodstain age.MethodsUnder laboratory conditions(20 ℃, 25 ℃and 30 ℃), an integrating sphere ISR-240A was used as a reflection accessory on an UV-2450 UV-vis spectrophotometer, and a standard white board of BaSO4 was used as reference, the reflection spectrums of bloodstain from human ears’venous blood were measured at regu-lar intervals. The reflection radiosR541 andR577 at a specific wavelength were collected and the value of R541/R577 was calculated. The linear fitting and regression analysis were done by SPSS 17.0.ResultsThe results of regression analysis showed thatR2 of the ratios of bloodstain age to UV visible reflectivity in specific wavelengths were larger than 0.8 within 8 hours and under certain circumstances. The regression equation was established. The bloodstain age had significant correlation with the value ofR541/R577.Con-clusionThe method of inspection is simple, rapid and nondestructive with a good reliability, and can be used to identify the bloodstain age within 8 hours elapsed-time standards under laboratory conditions.

The actual incidence of gastrointestinal stromal tumor (GIST) is underestimated.With the progression of awareness and development of examination methods,the detection rate of small GIST (diameter ＜ 5 cm) is increasing year by year.These patients always had no obvious clinical symptoms,and were often detected with small GIST in physical examination unexpectedly.Combination of endoscopic ultrasound and radiographic examination is helpful in detecting small GIST.Aggressive surgical complete resection should be considered in case of a definitive diagnosis.Laparoscopic resection is becoming the standard surgical treatment currently.For micro GIST (diameter ＜2 cm),especially micro gastric stromal tumor,current guidelines recommend close observation.Some scholars advocate that endoscopic resection is feasible for the treatment of micro GIST,while we think that the efficacy of individualized treatment is better after identifying the potential malignancy of micro GIST.

Objective To investigate the therapeutic efficacy of surgical treatment of myocardial bridge. Methods Fifteen patients with myocardial bridge had been treated in our hospital from January 1999 to October 2006. Thirteen patients who had typical angina had been treated regularly by medication, but their symptom remission was not satisfactory. One patient suffered from acute myocardial infarction, and another 1 patient complained of palpitation and syncope. All the patients were given surgical treatment. Surgical strategies included minimally invasive off-pump surgery in 9 patients (supraarterial myotomy in 3 patients, coronary artery bypass grafting in 2, and coronary artery bypass grafting with supraarterial myotomy in 4) and on-pump surgery in 6 patients (coronary artery bypass grafting with supraarterial myotomy in 5 patients and supraarterial myotomy in 1). Results All the operations were successfully completed. The operative duration of off-pump and on-pump surgery was 2.8?1.9 h and 3.5?1.7 h, respectively. The extracorporeal circulation time was 59?37 min. No surgery related death or complications occurred. At 3 months after operation, all the patients were free from symptoms, and electrocardiogram returned to normal in 11 patients. During a follow-up for 0.5~7 years (1.9?1.2 years), recurrent palpitation was seen in 1 patient and others reported no angina. Conclusions Surgical treatment of myocardial bridge has good immediate and long-term results.

Objective To investigate the pathological features of rabbit' retina at the early stage of sunlight-induced injury.Methods Twenty New Zealand rabbits without any eye diseases were randomly allocated to 4 groups(5 each): animals in group A were fed under normal illumination environment,the animals in group B were fed under normal illumination environment and exposed to constant simulated sunlight,the animals in group C were fed under low illumination environment,and the animals in group D were fed under low illumination environment and exposed to constant simulated sunlight.The pathological changes in rabbits' retina were observed with light and transmission electron microscope.Results The structure of retina in group A and group C were histologically well-defined,uniform in staining,and with regular cell shape.In the animals in group B,vesiculation occurred in the ganglion cell layer,inner nuclear layer and outer nuclear layer,and some of the mitochondria showed swelling.The intramembranous structure of external segments became disorganized.In the animals in group D,vesiculation and swelling occurred in the ganglion cell layer and inner nuclear layer,with disruption of the cell membrane.Vesiculation and swelling were also found in the outer nuclear layer,with reduction in cell quantity.The structure was disorganized,with disorganized cell membrane,obvious swelling of mitochondria,disorganized intramembranous structure of external segments,and loss and vesiculation of the laminal structure.Conclusion The rabbit' retina will be injured when it is exposed to 30 000 lux constant simulated sunlight for 30 minutes.Rabbits fed in a low illumination environment and exposed to constant simulated sunlight may suffer severer injury than those fed in a normal environment and exposed to constant simulated sunlight.
