Objective To study the imaging manifestati ons and diagnostic evaluation of rounded atelectasis.Methods Imaging manifestation of round atelectasis in 4 c ases confirmed by pathology with complete clinical data,plain chest radiographs and CT were analysed.Results The lesions in 4 cases appeared as circular or el liptic masses with clear boundary,2.6～6.5 cm in diameter,located at subpleura o f lower lobule of lung,accompanied with pleural thickening.There was a acute angl e between the tumor and thickened pleura.The lucency of the lung adjacent to tum or incneased.The cordike structures consisted of blood vessels and bronchil ente red into tumors,which made the lateral boundary of tumor to hilum of lung obscur ed.“comet tail sign”and “air-brochogram sign”were seen in 3 cases.Conclusion The round atelectasis is of typical findings o n plain chest films and CT scans which play a very important role in diagnosis a nd differential diagnosis.

A case of localized scleroderma associated with mandibular osteomyelitis is reported.The formation mechanism of the case is a-nalysised according to clinical characteristics and literature data.

Objective To study the setup accuracy and other factors during frameless stereotactic radiosurgery (SRS) of intracraial tumor using ExacTrac X-ray image guide system.Methods Totally 119 intracranial tumor patients from August 2014 to February 2016 underwent auto setup with infrared marker.Bilateral oblique cross field images were obtained with ExacTrac X-ray system,and went through comparison,registration and correction with the digitally reconstructed ones of the planning system.Then the translation accuracy errors at LAT,LNG and VRT directions and corresponding rotational accuracy errors were acquired,and the errors experienced extended analysis.Results The translation errors at LAT,LNG and VRT directions acquired with ExacTrac X-ray image guidance system and 6DOF couch were (0.16±0.13) mm,(0.17±0.14) mm and (0.15±0.11) mm respectively,the corresponding rotational errors were (0.21±0.15),(0.18±0.15),(0.18±0.14)° respectively,and the vector error was (0.32±0.16) mm.All of 3 translation and 3 rotational errors were in the SRS error range.Conclusion ExacTrac X-ray image guidance system combined with 6 degrees-of-freedom couch increases the treatment accuracy during frameless SRS,and thus is worthy promoting practically.

Objective To investigate the adverse effects of taurine on rabbit corneal endothelial cells. Methods Six rabbits (12 eyes) were selected, and 6 histologic sections were prepared from each of the eyes. Rabbit corneal endothelial cells were cultured by explant culture method. Cells were innoculated on a 12-well tissue culture plate, 2%, 4%, 6%, 8% and 10% taurine solutions were added respectively (cells from the right and left eyes of the same rabbit were added the same concentration of taurine solution), and blank control was established. The growth of corneal endothelial cells was observed by inverted microscopy, and cell morphology on the 1st, 2nd, 4th, 6th and 8th day of culture was observed with Wright staining. Results Corneal endothelial cells cultured with 2%, 4% and 6% taurine solutions and those of blank control formed endothelial cell layers after culture for one week, and the cells exhibited hexagonal or round-like morphology. Corneal endothelial cells cultured with 8% taurine solution appeared to be undergrowth with small cell body on the 4th day, and cell death occurred on the 8th day. Corneal endothelial cells cultured with 10% taurine solution turned out to be undergrowth with small cell body on the 2nd day, and cell death had occurred. The same growth velocity and cell morphology were observed in the corneal endothelial cells from the right and left eyes of the same rabbit. Conclusion Taurine with concentration between 2% and 6% has no adverse effects on the growth of rabbit corneal endothelial cells.

OBJECTIVETo investigate the protective effects of daidzein (DD) on ventricular remodeling in rats with myocardial hypertrophy induced by pressure overload and its mechanism.

METHODMyocardial hypertrophy model of rats induced by pressure overload was prepared by constricting abdominal aorta. The operated rats were randomly divided into sham operated control group, aorta-constricted model group and three DD groups (30, 60, 120 mg kg(-1)). Four weeks later, the heart-weight (HW), left ventricular weight (LVW), the ratio of HW/BW and LVW/BW (LVI) and the cardio-myocyte diameters (MD) after dyeing by HE colar were measured. The hydroxyroline, nitric oxide (NO) and the activity of nitric oxide synthetase (NOS) and Na+ -K+ -ATPase, Ca2+ -ATPase in left ventricle were quantified with spectrophotometry and the angiotension II (Ang II) in left ventricle and serum was messured with radioimmunoassay.

RESULTAfter treatment of the left ventricular with DD, vs aorta-contricted model group, NO content, cNOS and Na+ -K+ -ATPase, Ca2+ -ATPase activity were significantly increased, the content of AngII in left ventricle and serum and iNOS activity and the ratio of HW/BW, LVI, MD were significantly reduced.

CONCLUSIONDD has protective effects on ventricular remodeling in rats with myocardial hypertrophy induced by pressure overload and its mechanism may be related to raising NO content and reducing the level of Ang II.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.
