BACKGROUND:Recent studies have found that femoral neck angleαin patient with femoral neck hernial fossa increased significantly. However, whether the femoral neck hernia fossa can be used as imaging diagnostic indicator for femoroacetabular impingement syndrome remains controversial. OBJECTIVE:To evaluate the association between alpha angle and herniation pit in asymptomatic hip joints, influencing factors of the above indexes, and to provide evidence for the diagnosis of hip impingement syndrome. METHODS:Adults with asymptomatic hip joints from September 2013 to December 2015 were retrospectively studied. Alpha angles were measured on oblique axial MRI images. The incidence and size of herniation pit were determined by MRI. Size measures, prevalence, and statistical analyses were conducted regarding its association with age, gender, laterality (right or left hip). Intra-and inter-observer consistency was determined by intra-class correlation coefficient. RESULTS AND CONCLUSION:(1) 105 patients with asymptomatic hips were included, and 185 sides of hip MRI images were obtained. The range of age was 18-80 years old. The prevalence of herniation pit in asymptomatic hips was 21.6%. (2) The range of alpha angle was 27.6°–65.0°. Alpha angles of hip joints of 17 cases were ≥ 55°. (3) There was no association between alpha angle≥55° and the size of herniation pit (P>0.05). The prevalence of herniation pit was not correlated with age, gender and affected side (P=0.160, 0.157, 0.110). Inter-observer consistency of alpha angle was 0.523 between first measurements of first vs. second observer, respectively. Intra-observer consistency of alpha angle was 0.654, respectively. (4) There is no association between alpha angle ≥ 55 degrees and presence of herniation pit or demographic variables (age, gender and affected side). The presence of herniation pit and the increased alpha angle need to be interpreted with caution. Clinical symptoms and other examinations should be used in the diagnosis of hip impingement syndrome.

Objective To explore the value of intravascular ultrasound (IVUS) in diagnosing plaque disruption and arterial thrombosis.Methods Balloon-induced arterial wall injury and then feeding on a diet of 1% cholesterol for 8 weeks, 17 New Zealand white rabbits were established as atherosis(AS) models.At the end of the eighth week, the resulting plaques were incubated transluminally with recombinant adenovirus carrying a p53 transgene. After two weeks, the rabbits underwent pharmacological triggering with Russell viper venom(RVV) and histamine. IVUS was used before and after the rabbits were triggered pharmacologically. The value of IVUS in diagnosing plaque disruption and arterial thrombosis was derived by comparing the results of IVUS with pathologic findings. Results IVUS found that plaques disruption and thrombosis occurred in 12 of the 14 rabbits, totally 18 thrombi. A histologically confirmed plaque disruption and intraluminal thrombus were visualized in 12 of the 14 rabbits, totally 20 thrombi. By comparing the results of IVUS with histopathology, the true positive rate was 85% and false negative rate was 15%, the sensitivity and specificity of IVUS were respectively 85% and 67%. IVUS data correlated well with the histopathology regarding thrombus length(r=(0.73),P(0.05)). Conclusions IVUS can detect plaque disruption and arterial thrombosis.

Background Prostaglandin eye drops is front-line medicines of lowing intraocular pressure for primary open angle glaucoma (POAG),but its price is higher for long-term application.Domestic latanoprost drops has been applied in clinic.However,its trial of lowing intraocular pressure effect and safety from sizable sample and multi-center is lack.Objective This study was to observe the efficacy and safety of domestic latanoprost for POAG and ocular hypertension.Methods This prospective,multicenter trial was conducted at 25 hospitals in 5 territories of China,and 837 eyes of 576 patients with POAG and ocular hypertension were recruited in the hospitals based on the uniform criteria.Domestic latanoprost drops was topically used once per day at night for 3 months.Intraocular pressure (IOP) was measured 1 month and 2 months,3 months to assess the efficacy of drug,and vision acuity,blood pressure,pulse,ocular symptoms and signs were observed to evaluate the safety of the drug.This study approved by the Ethics Committee of Wuhan General Hospital of Guangzhou Military Command,and all patients were informed consent and signed informed consent.Results IOP was (28.36±7.86),(19.66±5.46),(19.59±7.86) and (19.35 ± 5.03) mmHg in pretreatment and posttreatment 1 month,2 months and 3 months,respectively,showing a significant difference among various time points (F =748.325,P =0.000),and the IOPs were markedly lower in posttreatment than those in pretreatment (all at P＜0.001).The falling range of IOP was (30.43 ±7.18)％,(30.19 ± 8.72)％,(30.71±9.90) ％ in posttreatment 1 month,2 months and 3 months,respectively.The efficiency was 95.70％,91.76％ and 88.05％ in 1 month,2 months and 3 months.Conjunctival hyperemia was observed in 13％ eyes at the end of following-up.No drug-related systemic and other ocular adverse reactions were found.Conclusions Domestic latanoprost drops can low IOP effectively without serious adverse reaction in POAG and ocular hypertensive patients.

Objective To explore the difference of DISC1 gene polymorphism between schizophrenia patients and normal subjects,as well as the association of gene polymorphism with mRNA expression.methods 40 schizophrenia patients and 40 normal subjects were recruited randomly from southern region of Fujian,China.DISC1 mRNA level was assessed by RT-PCR and the genotype was evaluated by sequencing with the amplified PCR products from peripheral blood DNA.Result srs6675281 locus only found CC type,other types were not found.According to the genotyping Result ,the rs821616 locus has AA,AT and TT three types,but the genotype and allele frequency between the two groups were not significantly different (Genotype:x2=0.923,P=0.63;Allele:A>T,x2=0.656,P=0.418).As far as rs11122319 locus,AA,AG and GG three types were found in this study,there was no significant difference between patients and normal controls (Genotype:x2=3.922,P=0.141;Allele:A>G,x2=0.184,P=0.668).Subjects were divided into AA,AG,GG three types based on rs1417584 locus genotyping,however the genotypes and alleles of this locus between the two groups were significant difference (Genotype:x2=6.631,P=0.042;Allele:A>G,x2=4.592,P=0.032),and the DISC1 mRNA expression that corresponding to the genotype AG in patients and normal subjects was significantly different (t=3.916,P=0.004).Conclusion Based on these findings,rs1417584 locus may be implicated the expression and regulation of DISC1 gene,may be a pathogenic factor of schizophrenia and the genotype AG may be corresponding to a higher risk.

Objective To explore the efficacy of transurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy for bladder calculus.MethodsBy using transurethral F20.8 nephroscope and EMS LithoCaster,we performed transurethral nephroscopic pneumatic lithotripsy and ultrasound lithotripsy on 69 patients with bladder calculus(63 men and 6 women)between October 2005 and May 2008.The diameter of the calculi was ranged from 1.5 to 6.0 cm.Among the patients,42 had one stone in the bladder,while 27 had multiple calculi.Fifty-five patients were complicated with BPH,14 had neurogenic bladder,and 4 showed bladder diverticulum with stones in situ.Pneumatic frequency was set at 8-12 Hz,and ultrasonic energy was 50%-60%.For the patients with BPH electrovaporization ablation was plused.ResultsAmong the 69 patients,68 were cured in one session.The mean operation time was 25 minutes(15 to 40 minutes).One patient was converted to open surgery because of rupture of the bladder during the procedure.No patient had urethral stricture,infection,or massive hemorrhage during the operation.Follow-up was available in 68 patients for 6 to 10 months(mean,9 months).During the period,no recurrent calculi was found by ultrasonography and X-ray.ConclusionTransurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy is effective for bladder calculus.

We present a case of subarachnoid hemorrhage induced by chronic suppurative otitis media and discuss the possible mechanism here. Chronic suppurative otitis media is a common suppurative inflammation of middle ear, which can cause sorts of extracranial and intracranial complications in the situation of lower resistance or higher virulence. However, the condition of subarachnoid haemorrhage caused by chronic suppurative otitis media is quite rare. According to this case and previously published articles, we consider that meningitis may be the main reason of subarachnoid hemorrhage induced by chronic suppurative otitis media.
