Objective To investigate the CT features of desmoplastic small round cell tumor (DSRCT)occurred in abdomen and pelvis.Methods The CT images of 4 patients with pathologically proven DSRCT occurred in abdomen and pelvis were retrospectively analyzed.Results The CT features common to the 4 DSRCT in abdomen and pelvis were as follows:the lobulated soft-tissue masses were very large;the masses often involved omental and serosal surfaces of abdomen and pelvis organ and had close relationship to the surrounding organs;the originating site of the tumors were not apparent;intratumoral hemorrhage or necrosis were often present;and contrast-enhanced CT scan showed mild to medium heterogeneous enhancement.Conclusion The CT features of DSRCT in abdomen and pelvis are rather specific and can provide helpful information to the clinical diagnosis.

The nutritional status in early life have been gradually recognized that it can change the status of development and metabolism of adults.Epidemiological evidence and animal model study have found that low birth weight is the risk factors of adult metabolic syndrome and cardiovascular disease.Insulin resistance is a common pathophysiological basis.Renin-angiotensin system and insulin signaling systems interact to promote the development of insulin resistance.

Background Patients' experience during phacoemulsification cataract surgery is an important determinant of patient's satisfaction with surgery effectiveness.Local anaesthesia could be associated with different intraoperative visual awareness because of retention of optic nerve function.Relieving the anxiety of patients arose from intraoperative visual awareness is of important clinical significance.Objective This study was to discuss the necessity of preoperative conversation and psychological counseling and to improve the quality of surgery and the satisfaction of patients.Methods One hundred and fifty-three patients who had undergone sequential phacoemulsification and intraocular lens (IOL) implantation in the same operation under local anaesthesia from October,2010 to December,2010 in Tangdu Hospital and Xi'an First People's Hospital,received a standardized questionnaire designed based on similar questionnaires from abroad and surveyed regarding their intraoperative visual experience,including light perception,their detection of color,photopsia,and their detection of the movement of the surgeon,instrument,and changes in light intensity during cataract surgery.In another survey,seventy ophthalmologists in the Xi'an area with ≥ 10 years (33) and ＜ 10 years of experience (37) participated in a questionnaire about their recognition and response to these visual experiences,designed based on the 2010 Chinese Doctors General Questionnaire.Results During the phacoemulsification and IOL implantation,27 patients (17.6％) lost light perception,98 patients (64.1％) had light perception,28 patients (18.3％) detected more than one color,25 patients (16.3％) had photopsia,49 patients (45.1％) sensed the movement of the surgeon,26 patients (17.0％) was able to see surgical instruments,11 patients (7.2％) saw the surgeon's fingers,4 patients (2.6％) saw the surgeons,65 patients (42.5％) detected changes in light intensity and 12 patients (7.8％) saw the IOL loop and others.21.4％ of the 70ophthalmologists believed these patients might have lost light perception;while 78.3％ thought these patients retained light perception.Under local anaesthesia,93.9％ of the more experienced surgeons and 75.6％ of the junior surgeons deemed that good preoperative counseling was helpful for the patients,but only 45.5％ of the more experienced surgeons and 24.3％ of the junior surgeons counseled patients regarding intraoperative visual experience.Conclusions Most patients will experience a variety of visual sensations during phacoemulsification and IOL implantation under local anaesthesia.Many ophthalmologists are aware of these conditions.Most of the ophthalmologists believe that patients suffer from fear from these intraoperative visual experiences and claim that preoperative counseling to patients can relieve that fear,but less of them communicate these possible experiences to patients.This study offers some discussions about preoperative counseling.

Objective:To evaluate the effect of HRCT in diagnosis of the sacroiliac joint of ankylosing spondylitis(AS).Methods:HRCT scanning of sacroiliac joints were performed in 86 adult patients with AS.CT findings were reviewed.Rank test was used for statistical analysis of the grade of sacroiliac joint changes in two groups based on course of disease and the sex of patients.Results:The CT findings of the sacroiliac joint changes in AS included erosion,arthrosclerosis,change of joint space,arthrokleisis,gas and soft tissue in articular cavity.Pathologic changes were more obvious with the course of disease prolonged (P0.01).In the group during the same course,pathologic changes were more marked in female patients than those in male ones(P0.01).Conclusion:HRCT can show tiny structures of sacroitiac joint clearly.This is beneficial to recognize different patologic changes and make correct diagnosis.

Fungal polyketide synthases are responsible for the biosynthesis of secondary metabolites such as pigments, mycotoxins, and they are very important in pharmacology , food science and agriculture. The recent advances in the methods for the isolation and manipulation of multiple classes of polyketide synthase genes from fungi were introduced. It is useful for discovery of novel fungal polyketide synthase gene clusters. These methods can also be useful for revealing the genetic potential of fungi to produce multiple types of bioactive polyketide.

Objective To examine the relationship of heparanase expression and age, clinicopathological features and prognosis of ovarian cancer patients. Methods Forty-one ovarian cancer specimens, from the patients admitted to the 3 hospitals of our university during the period of Jan 2003 to Nov 2005, were of serous carcinoma (22 cases) and mucous carcinoma (10 cases) and other types (9 cases), of which 16 were well and moderately differentiated and 25 poorly differentiated. Ten specimens of normal ovarian tissues were taken as normal controls. The heparanase expression was detected in all specimens and its relationship with histologic type, differentiation, FIGO stage and prognosis of the ovarian cancer was analyzed. Results The positive rate of heparanase expression was 80.48% in ovarian cancer tissues and 10.00% in normal ovarian tissues (P

Abstract?AIM: To observe the effect of acute angle closure glaucoma with cataract patients treated with glaucoma trabeculectomy combined two incision phacoemulsification and intraocular lens ( IOL ) implantation ( two incision triple surgery) .?METHODS: Patients admitted in our hospital during Jan.2013 to Jan.2016.The acute angle closure glaucoma with cataract patients in 40 cases ( 58 eyes ) were randomly divided into two groups:the observation group of 20 cases ( 29 eyes ) with two incision triple surgery treatment, and the control group of 20 cases ( 29 eyes ) with single incision triple after treatment.Visual acuity, intraocular pressure, bleb, corneal endothelial cell density, the area at 1mo before and after surgery, and postoperative complications of two groups were analyzed.?RESULTS: Postoperative visual acuity of two groups were significantly improved, but there was no significant difference between groups ( P >0.05 ); postoperative intraocular pressure, bleb formation rate of the observation group were 14.41 ±1.38mmHg, 90%, and the control group 14.40 ±1.40mmHg, 86% without statistical significance ( P>0.05 ), corneal endothelial cell density and area of observation group after 1mo were 1696.6±300. 8/mm2 , 540.8±71.6μm2 , and control group 1410.6±288.5/mm2 and 594.3 ±72.8μm2 with significant differences ( P<0.05).The incidence rate of compli-cation was 17%in the observation group, and 21%in control group (P>0.05).?CONCLUSION: For patients with acute angle closure glaucoma and cataract given two incision triple surgery and single incision triple surgery treatment can get good outcomes, but the effect of double incision on corneal endothelial cell injury is less.

Objective To observe how exogenous estrogen influences the distribution and the expression of NOS positive neurons in the supraoptic nuclei of hypothalamus in the overiectomized female rats. Methods The 2-3-month-old female rats(n=40) were selected as the healthy and nulli-copulatory experimental animals. Rats were divided into following groups: normal control group(n=10), ovariectomized control group(n=10), and two experimental groups that have been injected with estrogen for post-operative 40 days(n=10) and for post-operative 70 days(n=10). Finally, all the animals were infused and the brains were removed. Immunohistochemical (SABC) method was adopted to count the number of NOS poitive neurons and observed the NOS poitive neuronal morphology under the light microscope. The image analysis system was used to test the average gray value of immunoreactivity in NOS positive neurons. Results In the ovariectomized control group, the density of NOS positive neurons in supraoptic nucleus was significantly increased and their shapes were bigger than that of the normal control group(P<0.05). The density and the form of the NOS positive neurons in supraoptic nucleons had no apparent difference between the estrogen for post-operative 40 days group and the ovariectomizeed control group(P>0.05).In the group after estrogen-injection 2 months compared with the normal control group, and the ovariectomized control group, both of the NOS positive neurons' density and the size become significantly decreased, and the staining of cells was lesser in the group injected with estrogen for post-operation 70 days. Conclusion The present results suggest that exogenous estrogen may influence the distribution and the expression of NOS positive neurons in supraoptic nucleus of hypothalamus of ovariectomized female rats.

Objective To study the relationships between serum intedeukin-18(IL-18)and resistin for predicting intraamniotic infection.Method Serum levels of IL-18 and resistin were measured in 43 pregnant women with intraamniotic infection (infection group)and 40 normal pregnant women(control group).Results The level of IL-18 in infection group[(38.7±10.4)μg/L]was higher than that in control group [(23.5±5.6)μg/L],there was significant difference between two groups (P＜0.01).The level of resistin in infection group[(24.84±5.32)μg/L]was higher than that in control group[(17.3±5.15) μg/L],there was significant difference between two groups(P＜0.01).The levels of resistin and IL-18 were correlated in pregnant women with intraamniotic infection(r=0.61,P＜0.01).Conclusion Detecting the levels of IL-18 and resistin in pregnant women can identify intramnniotic infection.
