Objective To investigate the roles of high-resolution magnetic resonance imaging (HR-MRI) in the diagnosis and treatment of vertebrobasilar dissecting aneurysms (VBDA).Methods From January 2016 to December 2016,62 patients with VBDA admitted to Xuanwu Hospital,Capital Medical University using 3.0 T HR-MRI (3D-TOF-MRA,3D-T1WI,and 3D-T1WI+C sequence) and diagnosed by DSA were analyzed retrospectively.They were divided into either an asymptomatic group (n=18) or a symptomatic group (n=44) according to their medical histories.Their clinical features,imaging features,and the relationship with prognosis were analyzed.Results HR-MRI revealed that the double lumen sign/intimal flap accounted for 27.8% (n=5) and 54.5% (n=24) respectively in the asymptomatic group and symptomatic group.The intramural hematoma accounted for 22.2% (n=4) and 43.2% (n=19) respectively in both groups.The enhancement of aneurysmal wall accounted for 33.3% (n=6) and 77.3% (n=34) in the asymptomatic group and symptomatic group.There were significant differences in the above features between the two groups (all P<0.05).In the symptomatic group,18.2% (n=8) of patients had aneurysm recurrence,which was significantly higher than the asymptomatic group (5.6%,n=1).The difference between the two groups was statistically significant (P<0.05).Conclusions HR-MRI can better reveal the lesion characteristics of VBDA.The rates of aneurysmal wall enhancement and recurrence in symptomatic VBDAs are higher,which indicates that HR-MRI can assess the stability of the aneurysmal wall and identify the prognosis to a certain extent.

Objective To evaluate the efficacy of the parathyroidectomy (PTX) in the treatment of severe secondary hyperparathyroidism (SHPT) with Sagliker syndrome (SS). Methods A retrospective review was undertaken among 212 SS patients underwent PTX in our hospital and with more than 3 years' follow up. The definitions of the efficacy were based on the postoperative intact parathyroid hormone level (iPTH). Cure showed that the iPTH was ＜ 150 ng/L; marked effectiveness was 150-300 ng/L; effectiveness was 301-500 ng/L;ineffectiveness was ＞500 ng/L. The status was defined as persistent SHPT if iPTH was ＞ 150 ng/L after surgery. The status was considered as SHPT recurrence if iPTH was ＜ 100 ng/L in the first week after surgery, and gradually increased and ＞ 150 ng/L with the follow-up. Results ( 1) Ten patients were involved and the average dialysis time was 142 months [male/female: 4/6; age 30-54 (39. 3 ± 10. 4) years]. All patients had severe bone and joint pain, accompanied with progressive facial increases, chicken breast, kyphosis, hip bone deformities, and body height shortening. (2) Preoperative tests: the median of iPTH 2000(1800-2863) ng/L; serum calcium (2. 45 ±0. 21) mmol/L, phosphorus (2. 19 ±0. 51) mmol/L, alkaline phosphatase ( ALP) (1189. 8 ± 780. 0) IU/L. Two to four enlarged parathyroid glands were confirmed by ultrasound and 99Tcm-MIBI parathyroid scintigraphy. ( 3 ) Surgical procedures: local or general anesthesia for PTX. Supplement with calcium and calcitriol implemented low serum calcium after PTX. (4) Follow-up: symptoms, including bone pain, muscle weakness, skin itching, and insomnia, were significantly improved after surgery. Transient hoarseness occurred in 2 cases. The iPTHs of all patients were decreased significantly after surgery. The median of iPTH was 55.5 ( 10-967) ng/L at 1 month post PTX, and was significantly less than prior to PTX (P＜0. 001). Eight patients were cure , 1 marked effectiveness ,and 1 ineffectiveness. Two patients were persistent SHPT, and 1 died of heart failure in the 4th year after PTX. The development of bone deformities was stopped and malnutrition was improved in long-time follow up. The level of iPTH 135(28-390)ng/L(P＜0. 001 ) , serum calcium, phosphorus, and ALP showed normal in the third year. The SHPT recurrence was appeared in the 2nd and 3rd year in 2 out of 8 patients, respectively. Conclusions Total PTX can effectively treat SS by SHPT. It can improve prognosis for patients, such as bone pain disappearing, bone deformities stopping and malnutrition improving, etc. The level of iPTH may rise again in some patients in the future. Therefore, more attentions should be paid to monitoring.

Data were gathered from epidemiological survey of Xinjiang Hetian area in 2008 and 2 228 subjects were included.Waist-height ratio (WHtR),body mass index (BMI),Waist-hip ratio (WHpR) were calculated.Kappa test was applied to determine the concordance among different methods.The results showed that according to International Diabetes Federation 2005 diagnostic criteria for metabolic syndrome,it was better to apply WHtR in predicting metabolic syndrome by the receiver operating characteristic (ROC) curve than BMI,abdominal circumference,and WHpR.When the cutoff of WHtR was 0.53,the sensitivity and specificity in diagnosing MS were 91.2％ and 71.8 ％,with its area under ROC curve 0.878.Kappa test showed an intensive concordance between WHtR and waist circumference (WC).The specificity and sensitivity of diagnosing MS would be significantly raised by using both WHtR and WC.

BackgroundDry eye is a multi-factorial-induced tear film and ocular surface disorder.Immunoinflammation plays a key role in the pathogenesis of dry eye.As inhibitor of the cyclo-oxygenase pathway,nonsteroidal anti-inflammatory drugs play an anti-inflammatory and anti-hypersensitivity role,and it can be a potential treatment for dry eyes.ObjectiveThis study was to investigate the effectiveness of nonsteroidal anti-inflammatory drugs (0.1％topical pranoprofen) on moderate to severe dry eyes and its mechanism.MethodsThis was a small sample of randomized controlled clinical trial.Thirty right eyes of 30 patients with moderate to severe dry eyes were included in the study according to the diagnosis criteria and randomized into two groups.The patients of the trial group received topical administration of 0.1％ pranoprofen plus 0.1％ sodium hyaluronate,and those of the control group received the topical 0.1％ sodium hyaluronate only.Ocular surface inflammation index scores (OSDI) and ocular surface fluorescine staining (OSS) scores were measured under the slit lamp,and tear film break-up time (BUT),Schirmer Ⅰ test values were evaluated.The expression of human leucocyte antigen-DR (HLA-DR) and CD11b in conjunctiva epithelial cells were detected by impression cytology and flow cytometry (FCM).All the indexes were compared between the two groups before and after treatment.Informed consent was obtained from all patients.ResultsThere were no significant differences in terms of age and gender and their baseline values between the trial group and control group (t=0.412,P=0.684;x2=0.240,P=0.624),and so were all the indexes (P＞0.05).Compared with the control group,the OSDI,OSS scores and cells positive for HLA-DR were lowered but the BUT was delayed in the trial group on day 15 ( t=2.43,P=0.03;t=2.83,P=0.01;t=3.29,P=0.00;t=3.23,P=0.00 ).No significant differences were found in the Schirmer Ⅰ test value and CD11b expression between these two groups (t=0.17,P=0.87;t=0.28,P=0.79).The OSDI,OSS scores and BUT were significantly improved,and the number of cells positive for HLA-DR were reduced 15 days after administration of drugs in comparison with before treatment in the trial group ( t =12.30,10.70,6.10,7.92,P =0.00 ).However,there were no comparable alteration seen in these indexes before and after the usage of drugs in the control group ( P＞0.05).Positive correlations were found in HLADR expression with OSDI and OSS ( r =0.601,P =0.018 ; r =0.586,P =0.022 ) and a negative correlation in HLADR expression with BUT (r=-0.697,P=0.004) on day 15 in the trial group.ConclusionsTopical usage of 0.1％ pranoprofen is beneficial for remitting the ocular signs and symptoms in moderate to severe dry eyes.This study illustrates that topical usage of 0.1％ pranoprofen can down-regulate the expression of inflammatory markers in conjunctival epithelial cells.

Objective: To explore therapeutic effect of in-hospital intravenous alprostadil injection on patients with acute myocardial infarction (AMI) complicated diabetic nephropathy (DN) undergoing percutaneous coronary intervention (PCI), and evaluate their long-term prognosis.Methods: A total of 80 AMI + DN patients undergoing PCI were selected from our hospital.They were randomly divided into alprostadil group (n=40) and routine treatment group (n=40).Renal function after PCI, cardiac function during hospitalization, serum creatinine (Scr) level on 72h after PCI and incidence of major adverse cardiovascular events (MACE) within one-year follow-up were compared between two groups.Results: Compared with routine treatment group on 72h after PCI, there was significant reduction in Scr level [(126.92±35.28) μmol/L vs.(104.32±22.91) μmol/L], and significant rise in estimated glomerular filtration rate [eGFR, (55.23±31.48) ml·min-1·1.73m-2 vs.(62.14±36.23) ml·min-1·1.73m-2] in alprostadil group, P<0.05 both.Postoperative one-year follow-up indicated that there were no significant difference in incidence rate of MACE and percentage of kidney replacement therapy between two groups, P>0.05 all.Conclusion: Intravenous alprostadil injection based on routine treatment possesses significant therapeutic effect on renal function in AMI + DN patients after PCI, and it's safe

AIMThe expression of VEGF in rat ovaries corpus luteum and its expression pattern were observed to investigate the effect of VEGF on luteal formation and regression.

METHODSThe model of immature rat of pseudopregnant was established using pregnant mare's serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG), the expression of VEGF in corpus luteum was detected by immunohistochemistry, the levels of VEGF in corpus luteum was measured by ELISA, and the levels of NO in corpus luteum was measured by chemistry assay.

RESULTSVEGF expressed weakly in rat corpus luteum on the day 1, and enhanced gradually from day 3 to day 5, then went up to the peak on the day 7, and maintained to day 9. On the day 11, the expression of VEGF began to decrease. The levels of VEGF were similar to the expression of VEGF. The levels of NO appeared like double wave. The levels increased gradually from day 1 to day 5, and peaked on the day 7, then decreased on the day 9, while lightly increased on the day 11, and showed significant increase and reached the highest on the day 13, then decreased the lowest on the day 15.

CONCLUSIONThere is a intimate temporal relationship between the expression of VEGF and angiogenesis in corpus luteum, VEGF may play a role in luteum formation by improving angiogenesis mediated by NO, NO may play a role in luteum regression as a luteolytic during the late luteal phase.

AIM: To investigate hemodynamic alterations of retrobulbar vessels in proliferative diabetic retinopathy ( PDR) patients with anterior segment neovascularization, before and 3mo after vitrectomy combined with panretinal photocoagulation and to explore the clinical significance.
●METHODS: Color Doppler flow imaging ( CDFl ) was used for measurement of blood flow velocities and resistive indexes ( Rl ) of the ophthalmic artery ( OA ) , short posterior ciliary arteries ( sPCA ) and central retinal artery ( CRA ) in 21 eyes of 21 PDR patients with anterior segment neovascularization. CDFl parameters were obtained before and 3mo after vitrectomy combined with panretinal photocoagulation ( PRP) .
● RESULTS: Peak systolic velocity ( PSV ) and end diastolic velocity ( EVD ) of CRA were significantly increased after surgeries, Rl were decreased significantly (P<0. 05). Parameters of sPCA and OA have no change after surgeries (P>0. 05).
●CONCLUSION: Vitrectomy combined with panretinal photocoagulation might increase the velocity of CRA, decrease Rl and improve ocular blood supply postoperatively. lt may delay or prevent the process of neovascular glaucoma.

Background It has been clarified that topical administration of cholinomimetic drug or prostaglandin analogus can effectively low intraoeular pressure (IOP) in primary angle-closure glaueoma and angleopen glaucoma,respectively.The two eyedrops are often combined clinically to treat glaueomatous eye.But their effect mechanism on ciliary muscle is different.It is neeessarv to prove the clinical efficacy of combination of these two drugs.Objective This study attempted to compare hypotensive effect of individual and combinative use of 2％piloearpine and 0.004％ travoprost in normal rabbit eyes.Methods Thirty normal albino rabbits were randomly divided into three parallel groups.Lateral eye of each rabbit was appointed as the experimental eye and the fellow eye was used as control eye.2％ Pilocarpine eyedrop was instilled three times daily and 0.004％ travoprost eyedrops was used once per night in the pilocarpine and travoprost group.These two drugs were combined in the combination group.The normal saline solution was used in the control eyes IOP was measured bilaterally with Perkins application tonometer at 8:00 am on the day before and 1,2,4,8,14,24 days after the administration of eyedrops.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The IOP was significantly lower on 1 day after use of eyedrops than baseline IOP in the experimental eyes in the pilocarpine group,travoprost group and combination group,but no obvious change in IOP before and after use of eyedrops in the control eyes.There was no significant difference in the baseline IOP in both experimental eyes and control eyes,however,signifieant differences were seen in various time points after administration of eyedrops between experimental eyes and control eyes(P＜0.05).Compared with baseline IOP,IOP declined by 17.5％-22.0％ in pilocarpine group,23.8％-26.4％ travoprost group,27.6％-32.0％ in the combination group.For normal eye,piloearpine+travoprost showed a more power lowing IOP effect.Conclusions Hypotensive effect of combinative use of 2％ pilcoarpine and 0.004％ travoprost is strongest in comparison with individual use of pilocarpine or travoprost,but less than the statistical sum of individual use of these two drugs in a 24-day duration in normal eye of albino rabbit.
