Objective:To observe the clinical efficacy of Gao's nape acupuncture plus swallowing training in treating pharyngeal deglutition disorder after stroke.Methods:One hundred patients with post-stroke pharyngeal deglutition disorder were randomized into a treatment group and a control group,with 50 cases in each group.The two groups both received routine neurological intervention.In addition,the treatment group was given Gao's nape acupuncture plus swallowing training,while the control group was intervened by swallowing training alone.After eight-week treatment,the two groups were observed in terms of the changes in repetitive saliva swallowing test (RSST),modified water swallowing test (MWST),standardized swallowing assessment (SSA) and swallowing-related quality of life (SWAL-QOL).The clinical efficacies of the two groups were also compared.Results:After treatment,the RSST grading,and scores of MWST,SSA and SWAL-QOL changed significantly in both groups (P＜0.05 or P＜0.01).The RSST grading,and scores of MWST,SSA and SWAL-QOL in the treatment group were significantly different from those in the control group after treatment (P＜0.05 or P＜0.01).The total effective rate and markedly effective rate were respectively 100.0％ and 72.3％ in the treatment group,versus 97.9％ and 34.0％ in the control group.There was a significant difference in the markedly effective rate between the two groups (P＜0.01).The difference in the clinical efficacy between the two groups was statistically significant (P＜0.01).Conclusion:Gao's nape acupuncture plus swallowing training is an effective approach for post-stroke pharyngeal deglutition disorder.Its therapeutic efficacy is more significant than that of swallowing training alone.

Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

Background Light stimulation at different wavelength influences the development of eyes.It has been showed that blue light can inhibit the growth of eyeball.To study whether blue light exposure can delay the extension of myopia is an interested research project.Objective This study was to investigate the effect of blue light with short wavelength on ocular growth in form deprived myopia (FDM) in guinea pigs and provide a new option for the prevention and treatment of myopia.Methods Thirty-six 2-week-old guinea pigs were reared in the environment of white light.The right eyes of the animals were occluded to establish the FDM models.The models were randomized into the deocclusion + blue light exposure group,simple deocclusion group and continuous occlusion group according to the random number table.The right eyes of the models were deoccluded for 1 hour per day to give the blue light (430 nm) irradiation in the deocclusion + blue light exposure group,and the right eyes were deoccluded for 1 hour per day only in the simple deocclusion group.In the continuous occlusion group,the right eyes of the models were occluded until the end of this experiment.Anterior chamber depth (ACD),lens thickness (LT) and vitreous cavity depth (VCD) were measured by A-type sonography.The binocular diopter of the guinea pigs was detected using retinoscopy in the mydriatic condition.In the fourth week after experiment,the retinal sections were prepared for the regular histopathological examination,and the scleral tissues next to 1 mm from optical nerve were exacted to obtain the dry weight of scleral tissues.Results In the right eyes of the animals,no significant differences were found in the diopter,ACD,LT and VCD before experiment among the 3 groups (all at P＞0.05).At the end of experiment,the refraction of right eye in the deocclusion + blue light exposure group,simple deocclusion group and continuous occlusion group was (+1.11±0.17)D,(+0.90±0.15)D and (-2.73±0.19)D respectively,with a significant difference among them (F=1 445.470,P=0.000).The VCD in the three groups was (3.70±0.09) mm,(3.78±0.11) mm and (3.91 ± 0.08) mm,respectively,showing a significant difference (F =13.243,P＜0.01).In addition,the dry weight of sclera tissues was (0.61 ±0.09)mg in the deocclusion + blue light exposure group,(0.54± 0.08)mg in the simple deocclusion group and (0.43 ± 0.07)mg in the continuous occlusion group,with a significant difference among the 3 groups (F=10.458,P＜0.01).However,there were no significant differences in the ACD and LT among the 3 groups (F=0.203,0.084,both at P＞0.05).Moreover,in the left eyes,no significant differences were found in the diopter,ACD,LT and VCD before experiment among the 3 groups (all at P＞0.05);while at the end of the experiment,the diopter of the continuous occlusion group was significantly lower than that of the deocclusion + blue light exposure group and simple deocclusion group (all at P＜0.05).No significant differences were seen in the ACD,LT,VCD and dry weight of sclera among the 3 groups (all at P＞0.05).Retinal structure was normal in the left eyes of various groups.However,the retinas were thinner in the right eyes of the deocclusion + blue light exposure group with clear layers; while atrophy of the outer segment of photoreceptor and disorder of cell arrangement were seen in the right eyes of the continuous occlusion group.Conclusions During sensitive period of visual development,blue light stimulation can arrest the extension of posterior sclera and elongation of vitreous cavity,which restrains development of myopia.This blue light at the wavelength of 430 nm is safe to retina.

To investigate the prevalence of Enterococcus faecalis in saliva and filled root canals of patients requiring endodontic retreatment for apical periodontitis. Patients with apical periodontitis who were referred for endodontic retreatment were examined. The type and quality of the restoration, symptoms, quality of obturation were recorded. During retreatment, an oral rinse sample and root canal sample were cultured using brain-heart infusion agar and bile esculinazide agar to select for E. faecalis. The 16S rRNA technique was used to identify E. faecalis. A total of 32 women and 22 men (mean age: 38 years; s.d.: 11 years) and 58 teeth were studied. The prevalence of E. faecalis was 19% in the saliva and 38% in the root canals. The odds that root canals harbored E. faecalis were increased if the saliva habored this bacterium (odds ratio=9.7; 95% confidence interval=1.8-51.6; P<0.05). Teeth with unsatisfactory root obturation had more cultivable bacterial species in root canals than teeth with satisfactory root obturation (P<0.05). E. faecalis is more common in root canals of teeth with apical periodontitis than in saliva. The prevalence of E. faecalis in root canals is associated with the presence of E. faecalis in saliva.

OBJECTIVETo observe the clinical significance of postoperative personalized antithrombotic therapy for patients with hemophilic arthritis (HA) patients after arthroplasty.

METHODSFrom September 2005 to October 2013, 11 cases of arthroplasty for hemophilic arthritis in hip and knee total operation 14 times,including 1 case of double knees (calculated as one operation), operation in left knees 6 times, operation in right knees 5 times, 2 in hip. All the patients were male and the age ranged from 23 to 57 years old,with an average of (36.1 ± 11.0) years old; the average weight was (64.1 ± 8.9) kg. All the patients were preoperatively diagnosed and classified as hemophilic arthritis with the radiological images and laboratory tests. According to the function of joints, the risk of postoperative venous thromboembolism (VTE), and dynamic observation of Factor VIII:C (FVIII:C) activity, patients were treated with personalized antithrombus by adjusting the dosage of recombinant human coagulation factor VIII (Kogenate FS). All the patients were orderly divided into postoperatively distal joints moving group and none-moving group to observe the coagulation function.

RESULTSThe enrolled patients had no postoperative complication of VTE and pulmonary embolism (PE). The APTT and D-2 were different between two groups in the postoperative early stage. Length of hospital day was shorter in the moving group than none-moving group.

CONCLUSIONBecause of the self-coagulation disorder, patients with HA tended to bleed. However it doesn't mean that there is no risk of postoperative thrombosis. Therefore,it's important to determine how to control the balance between postoperative antithrombus, hemostasis,and coagulation factor replacement therapy after arthroplasty for HA. Postoperative moving has proved helpful for HA, especially in reducing the risk of hemostasis and shortening the time in hospital.
