Objective To investigate the CT performances and causes of misdiagnosis of parovarian cyst,to improve its diagnostic accuracy.Methods CT data of 75 patients with surgically and pathologically confirmed parovarian cyst were analyzed retrospectively. Results Among the 75 patients,there were 79 cysts,in which 48 patients (51 cysts)originated from the epoophoron and 27 patients (28 cysts) from the mesosalpinx.77 were simple serous cysts and 2 serous cystadenomas.38 were located in the right ovarian adnexa,36 in the left ovarian adnexa,3 in the anterosuperior uterus,1 in the rectouterine pouch and 1 in the right iliac fossa.The size of the cysts ranged from 10 mm × 13 mm to 174 mm × 227 mm.75 were single cysts and 4 double cysts,34 presented as ovoid cysts,25 as irregular cysts, 17 as round cysts and 3 as gourd-shaped cysts.All the 79 cysts showed clear boundaries,thin walls,non-mural nodules,cystic fluid with a homogeneous densitywith CT value of 0-31 HU.Enhanced scanning revealed curved “obvious enhancement of the fallopian tube”at the edge of 68 cysts.In addition,the ipsilateral ovary could be detected in 76 cysts.“Holding ball”was found in 1 9 cysts.Conclusion Indication in ipsilateral ovary,curved “obvious enhancement of the fallopian tube”at the edge of cysts and “holding ball”are distinctive CT performances of parovarian cysts.CT has an important diagnostic value in parovarian cyst.

Objective To investigate the effect of methylprednisolone on T helper 17 cell (Th17 cells) related cytokines (interleukin (IL)-23,17A,21,22,6,and tansforming growth factor (TGF)-β) in serum and cerebrospinal fluid from patients with relapsing remitting multiple sclerosis and their effects on the pathogenesis.Methods We recruited relapsing remitting multiple sclerosis group (38 patients)and noninflammatory neurological disease group (20 controls),and detected the levels of IL-23,IL-17A,IL-21,IL-22,TGF-β and IL-6 in serum and cerebrospinal fluid (CSF) with ELISA kit in both controls and patients before and after treatment by methylprednisolone.Results After treatment in relapsing remitting multiple sclerosis patients,IL-17A,IL-23,IL-21,and IL-22 levels in cerebrospinal fluid and serum were significantly decreased,however,they were still higher than that in the non-inflammatory neurological disease patients.TGF-β levels was significantly increased (serum:(17.2 ± 5.9) pg/ml vs (34.1 ± 6.5) pg/ml,t =14.351,P =0.000 ; CSF:(26.4 ± 4.7) pg/ml vs (73.2 ± 19.7) pg/ml,t =16.352,P =0.000).The levels of TGF-β in serum and CSF in patients before treatment were lower than those of in non-inflammatory neurological disease patients (serum:(30.2 ± 8.9) pg/ml,t =6.769,P =0.012 ; CSF:(3 1.4 ± 7.5) pg/ml,t =9.368,P =0.017).However,the levels of TGF-β in CSF in patients after treatment were significantly higher than those in non-inflammatory neurological disease patients (t =9.138,P =0.000).Correlation analysis showed that IL-23 and IL-17A were positive correlation in the serum of relapsing remitting multiple sclerosis patients before treatment.Moreover,positive correlations among IL-23,IL-17A and IL-21 were detected in the CSF of relapsing remitting multiple sclerosis patients before treatment.Conclusions Decreased levels of IL-23,IL-17A,IL-21 and IL-22,and elevated levels of TGF-β were detected in serum and CSF of patients with relapsing remitting multiple sclerosis after methylprednisolone treatment.IL-23,IL-17A,IL-21,IL-22 and TGF-β might involve in the pathogenesis of relapsing remitting multiple sclerosis.

Giant intracranial aneurysms refers to the diameter of aneurysms larger than 2.5 cm,which belongs to the complicated aneurysms,accounting for about 5% ofintracranial aneurysms;rupture of the aneurysms leads to extremely high disability rate and fatality rate.At present,surgical treatment,endovascular treatment and new composite (hybrid) surgery are the three major surgical approaches.We summarize the treatment approaches to promote an update on treatment of such aneurysms and give understanding on the development and direction of aneurysm treatment.

To explore how to create and optimize a promotion index system of medical quality evaluation, this article focuses on the hospital visiting process from patients, using analyzing collected those index system from couples of Grade Ⅲ hospitals in Beijing, and combining the results of literal study, field study and specialist consult, according to the different situation of general hospitals and specially hospitals, with the spirit of "maintaining the patients benefits, safeguarding the patients safety,and enhancing the medical quality", introduces the framework of the promotion index system, the rules to select the indicator, and so on, and discusses several problerns related to creating the index system.

Objective To explore the relations of morphologies of intracranial tiny aneurysms with gender,age,hypertension and aneurysm lesions of the patients.Methods A retrospective analysis of clinical data of 112 patients with intracranial tiny aneurysms,admitted to our hospital from January 2009 to December 2012,was performed; according to the aneurysm morphologies,these patients were divided into regular-shape and irregular-shape groups (n=56).The influences of age,gender,hypertension and aneurysm lesions of the patients in aneurysm morphologies were analyzed.Results Gender,age and hypertension were not the independent influence factors of aneurysm morphologies,while aneurysm lesions could significantly affect the aneurysm morphologies,being the independent influence factor of aneurysm morphologies (P=0.005).In the comparison of different distributions of tiny aneurysms,the intemal carotid artery and vertebral basilar artery had less irregular aneurysms than anterior communicating artery; the morphologies of small aneurysms in the anterior cerebral artery,posterior communicating artery and middle cerebral artery showed no significant differences as compared with those in the anterior communicating artery,which tended to having irregular shapes.Conclusion The aneurysm lesions are related to the aneurysm morphologies; anterior communicating artery is prone to having irregular-shape aneurysms.
