Objective To compare the curative effects of extraperitoneal laparoscopic hernia repair and tradi-tional hernia repair in the treatment of inguinal hernia.Methods The clinical data of 200 inguinal hernia patients in our hospital from October 2013 to Novermber 2015 were retrospectively analyzed.They were divided into traditional hernia repair group (100 cases)and laparoscopic hernia repair group (100 cases)according to different surgical treatment.The operation time,bed activity time and hospital stay of the two groups were detected.The uroschesis, hydrocele,incidence of postoperative pain and recurrence rate of the two groups were detected.Results The opera-tion time between the two groups had no significant difference(t =1.74,P >0.05).The bed activity time[(2.6 ± 1.6)h]and hospital stay[(5.7 ±2.1 )d]of the laparoscopic hernia repair group were better than the traditional hernia repair group[(9.1 ±3.3)h,(7.4 ±2.3)d,t =17.72,5.46,all P <0.05].The uroschesis 3.0%,hydrocele 0,incidence of postoperative pain 10.0% and recurrence rate 0 of the laparoscopic hernia repair group were lower than the traditional hernia repair group(21.0%,15.0%,50.0%,12.0%,χ2 =15.17,15.34,39.11,11.69,all P <0.05).Conclusion The recovery is fast in inguinal hernia patients treatment by extraperitoneal laparoscopic hernia repair,complication is little,which is worthy of application.

Serum Cholyglycine (CG)is a main component of human bile acid,one of the conjuga-ted bile acids formed by the combination of bile acid and glycine is synthesized in the liver cells.Glycochol-ic acid (CG)as a clinical indicator for detecting hepatobiliary disorders,and the traditional index of liver
function test compared has greater advantages,its detection for intrahepatic cholestasis,liver disease and biliary system diseases diagnosis,treatment and prognosis analysis of pregnancy to provide an important ba-sis.

Objective To explore the expression and significance of CXCL13 in gastric mucosa of children with nodular gastritis. Methods A total of 216 pediatric patients with clinically diagnosed gastritis under gastroscopy were randomly divided into nodular group and non-nodular group according to whether there were nodular changes under endoscopy. The pathological characteristics of gastric mucosa and the expression of CXCL13/CXCR5 in gastric mucosa of all patients were evaluated. Results The infection rates of Helicobacter pylori(HP)in gastric mucosa in nodule group(n=102)and non-nodular group(n=114)were 70.59% and 42.11%, respectively; the rate of severe mononuclear cell infiltration were 74.51% and 22.81%, respectively; the proportion of neutrophil infiltration were 62.75% and 33.33%, respectively; lymph follicles occurred in 64.71% and 20.18%, respectively; and there were statistical differences between the two groups (P<0.001). Positive staining of CXCL13 and CXCR5 were found in the gastric mucosa of all HP infected patients. The percentages of positive cells of CXCL13 and CXCR5 in the gastric mucosa of the nodules group were (71.33±7.14)% and (73.54 ± 7.92)%, which were higher than those in the non-nodule group (45.88 ± 5.92)% and (50.42 ± 5.98)%, respectively, and there were statistical differences (P<0.001). Conclusions Nodular gastritis in children is mainly associated with Hp infection. The expression of CXCL13/CXCR5 is increased in gastric mucosa in children with Hp infection, especially in nodular gastritis, it may be involved in the formation of lymphoid tissue in gastric mucosa.

Objective To analyze the clinical presentation , the mutation of the pathogenic genes and imaging features in a Chinese Han early-onset Alzheimer's disease pedigree.Methods A pedigree of Alzheimer's disease was collected.The DNA sequence of presenilin 1 (PSEN1), presenilin 2, micro-tubule associated protein tau ,β-amyloid precursor protein gene was analyzed , the clinical presentation , results of accessory examination , neuropsychological evaluation of the proband were investigated and the point mutations of some members of the family , 50 sporadic Alzheimer's disease patients , 50 normal controls were verified.Results The proband of the family appeared as language impairment , memory loss, personality change, repeated language, visuospatial impairment, mental and behavior disorder.The gene detection showed p.L226R mutation in the condon 226 in the exon 7 of PSEN1 gene of the proband and five other family members (Ⅲ1 ,Ⅲ2 ,Ⅲ4 ,Ⅲ6 ,Ⅲ7 ).The mother of the proband had the suspicious symptoms , and the sister and the brother of the proband had the similiar symptoms with the proband , all of whom died.Fifty sporadic Alzheimer'disease patients and 50 unrelated normal subjects did not have the mutation .The computed tomographic angiography showed that the brain blood vessels were normal and 18 F-fludeoxyglucose positron emission tomography (18F-FDG-PET) showed brain atrophy and hypometabolism in frontotemporal regions, parietal regions, hippocampal areas, however, the MRI, MRA and 18F-FDG-PET of the two mutation carriers (Ⅲ6 ,Ⅲ7 ) were all normal.Conclusion We reported a novel mutation in an early-onset Alzheimer's disease family presented as language impairment in the early stage of the disease , the p.L226R mutation of PSEN1, which may be a pathogenic mutation to cause the family's dementia.

Objective To investigate the frequency and location of cerebral microbleeds in cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL) to understand the imaging and clinical features of the disease.Methods Cranial magnetic resonance imaging and susceptibility-weighted imaging were assessed in seven symptomatic CADASIL patients in People's Hospital of Zhengzhou University from 2014 to 2017.Imaging features and clinical significance of these patients were analyzed retrospectively.Results The seven patients were diagnosed by Notch3 gene detection.Mutations were found in exon 11 in four cases,and in exon 4 in three cases.All the seven patients with CADASIL had cerebral microbleeds,the number of which was 108 (4-36).The number of cerebral microbleeds was found to be higher in cortico-subcortical region than in any other regions.One of CADASIL patients with cerebral microbleeds had intracerebral hemorrhage located in external capsule.The patient with intracerebral hemorrhage had hypertension and multiple cerebral microbleeds.Conclusions Cerebral microbleeds are common imaging characteristics in symptomatic CADASIL,most of which locate in cortico-subcortical region.Cerebral hemorrhage is one of the clinical manifestations of CADASIL patients.

Panic disorder (PD) is an acute paroxysmal anxiety disorder with poorly understood pathophysiology. The dorsal periaqueductal gray (dPAG) is involved in the genesis of PD. However, the downstream neurofunctional changes of the dPAG during panic attacks have yet to be evaluated in vivo. In this study, optogenetic stimulation to the dPAG was performed to induce panic-like behaviors, and in vivo positron emission tomography (PET) imaging with F-flurodeoxyglucose (F-FDG) was conducted to evaluate neurofunctional changes before and after the optogenetic stimulation. Compared with the baseline, post-optogenetic stimulation PET imaging demonstrated that the glucose metabolism significantly increased (P < 0.001) in dPAG, the cuneiform nucleus, the cerebellar lobule, the cingulate cortex, the alveus of the hippocampus, the primary visual cortex, the septohypothalamic nucleus, and the retrosplenial granular cortex but significantly decreased (P < 0.001) in the basal ganglia, the frontal cortex, the forceps minor corpus callosum, the primary somatosensory cortex, the primary motor cortex, the secondary visual cortex, and the dorsal lateral geniculate nucleus. Taken together, these data indicated that in vivo PET imaging can successfully detect downstream neurofunctional changes involved in the panic attacks after optogenetic stimulation to the dPAG.
