Objective To compare the clinical effects of different surgical management for obsolute glaucoma.Methods 31 eyes of absolute glaucoma were retrospectively analyzed,including 23 case 23 eyes(A group) with cyclocryotherapy,8 case 8 eyes(B group)with cyclocryotherapy combining with paracentesis of anterior chamber,the pain and duration were comparatively observed.Results In the cyclocryotherapy,the pain occurred in 23 eyes,the duration time was 3 to 10 days,the average time was 6.8 days.While 4 eyes occurred pain in the cyclocryotherapy combining with paracentesis of anterior chamber,the duration time was 1 to 3 days,the average time was 2.3 days.There was significant difference(P

OBJECTIVEFrictions of Lock-loose brackets with ligated main wings or all six wings were measured as they slid along archwires in dry and artificial saliva environments. The Lock-loose brackets were then compared with traditional brackets and self-ligating brackets.

METHODSThe surface states of the stainless steel archwires were observed with atomic force microscopy before and after mechanical traction. The Lock-loose brackets, traditional brackets, and self-ligating brackets used in this study were composed of 0.406 4 and 0.457 2 mm stainless steel round archwires and 0.457 2 mm x 0.634 9 mm and 0.482 6 mm x 0.634 9 mm stainless steel rectangular archwires. Two different ligating methods were applied to the Lock-loose brackets, i.e., main wings ligated and all six wings ligated. Frictions were measured by using an electronic universal testing machine.

RESULTSNo significant differences were found between the roughness of different archwires before and after mechanical traction in different brackets (P > 0.05). When the main wings of the Lock-loose brackets were ligated, the frictions of the four different stainless steel archwires were close to zero, and the difference with frictions of traditional brackets was significant (P < 0.05). When using 0.457 2 mm x 0.634 9 mm rectangular archwires, maximum friction (P < 0.05; significantly different from those of other brackets) was reached when all six wings of the Lock-loose brackets were ligated. Frictions in the dry state were higher than those in the wet state (P < 0.05).

CONCLUSIONThe Lock-loose brackets can adjust the friction efficiently with different ligating methods, thus solving the problem of low friction and strengthening anchorage.

Objective:To explore the impact of pain, functional disability, self-efficacy and social support on health-related quality of life (HRQOL) in gout patients.Methods:From November 2019 to January 2020, a total of 218 patients with gout were investigated using the general information questionnaire, Visual Analogue Scale, Health Assessment Questionnaire Disability Index, General Self-Efficacy Scale, Perceived Social Support Scale, and Gout Impact Scale. The structural equation model was established by AMOS 24.0 for parth analysis, and the mechanism of pain dysfuction, self-efficacy and social support affecting the quality of life in gout patients was tested.Results:The total score of Gout Impact Scale, pain, functional disability, self-efficacy and social support respectively was 59.94±18.39, 6.00±2.76, 0.25 0, 0.88, 23.39±6.40 and 62.92±8.24. Pain directly influenced HRQOL ( β=-0.293, P<0.01), and indirectly influenced HRQOL ( β=-0.039, P<0.05). Functional disability directly influenced HRQOL ( β=-0.244, P<0.01). Self-efficacy directly influenced HRQOL ( β=0.182, P<0.01), and indirectly influenced HRQOL ( β=0.202, P<0.01) through pain and functional disability. Social support indirectly influenced HRQOL ( β=0.278, P<0.01) through pain, functional disability and self-efficacy. Conclusions:HRQOL of patients among gout is affected by several factors, mainly affected by pain, functional disability and self-efficacy; and there are interactions among them. Targeted interventions should be strengthened to relieve pain, prevent or slow down the progress of physical disability, enhance self-efficacy and social support to improve HRQOL.

Objective:Charcot-Marie-Tooth disease (CMT) comprises a group of clinically and genetically heterogeneous inherited neuropathies with an estimated prevalence of 1 in 2500. This study aimed to analyze the clinical and mutational characteristics of Chinese CMT patients with MFN2, BSCL2 and LRSAM1 variants.Methods:In this study, genetic analysis was performed in 206 Chinese patients at Chinese PLA General Hospital from December 2012 to March 2020 with clinical diagnosis of CMT, and reported variants of MFN2, BSCL2 and LRSAM1 related to CMT2.Results:We reported ten MFN2 mutations in ten unrelated patients (7 male, 3 female), two of whom had positive family history. Three novel mutations were detected including c.475-2A>G (splicing); c.687dupA (p.E230Rfs*16) and c.558dupT (p.S186fs). We reported three BSCL2 mutations of four unrelated patients, including c.461C>G (p.S154W), c.461C>T(p.S154L), and novel variants of c.1309G>C (p.A437P) and c.845C>T (p.A282V). Furthermore, two novel variants of LRSAM1, including c.1930G>T (p.G644C) and c.1178T>A (p.L393Q) were detected in two unrelated patients.Conclusion:Mutational spectrum of MFN2-, BSCL2-and LRSAM1-related CMT disease is expanded with the identification of novel variants in Chinese patients.

Objective:To clarify the application value of direct cortical electrical stimulation (DES) in locating vestibular functional cortices and the distribution of vestibular functional cortices.Methods:Implantation of stereo-electroencephalography (SEEG) electrodes was performed in 17 drug-resistant epilepsy patients in our hospital from January 2016 to December 2019. The clinical data of these patients were retrospectively analyzed. DES was performed on these patients and stimulation sites eliciting vestibular symptoms were selected to evaluate accurately anatomic locations of stimulation sites eliciting vestibular symptoms in standard Montreal Neurological Institute (MNI) space, and acquired accurate vestibular functional maps in groups.Results:There were 33 stimulation sites eliciting vestibular symptoms, including 9 sites (28%) located in the supramarginal gyrus, 6 sites (18%) located in the precuneus, 6 sites (18%) located in the posterior insular cortex, 1 site (3%) located in the anterior insular cortex, 4 sites (12%) located in the superior temporal gyrus, 2 sites (6%) located in the middle temporal gyrus, 4 sites (12%) located in the precentral gyrus, and 1 site located in cingulate cortex (3%). Stimulation sites eliciting vestibular symptoms induced by lowest intensity located in the insular cortex (average intensity was 2.43 mA), and the average intensity of 6 stimulation sites located in the posterior insular cortex was 2.17 mA.Conclusion:The functional cortex associated with vestibular symptoms defined by DES sites including the insular cortex, superior temporal gyrus, middle temporal gyrus, superior marginal gyrus, precuneus, precentral gyrus, and cingulate cortex.

OBJECTIVETo assess the efficacy of sacral neuromodulation (SNM) in patients with intractable constipation.

METHODSA total of 7 patients with intractable constipation were treated with pereutaneous test stimulation of the S3 nerve root and were assessed by sacral never stimulation system in our department from January 2013 to January 2014. Four of these 7 patients received operation for constipation before. The efficacy was assessed by bowel habit diary, clinic constipation scores, subjective questionnaire and clinical signs.

RESULTSThe constipation symptoms were improved significantly in all the 7 patients. The frequency and volume of defecation per week were increased obviously, and the average urine was increased. Six patients underwent permanent implantation of the SNS system. After a median 4 months follow-up, the defecation frequency increased from 0.6 ± 0.5 to 8.0 ± 2.5 per week (P<0.01), and the defecation time decreased from (22.9 ± 11.5) to (3.7 ± 0.8) min (P<0.01). The Cleveland clinic constipation score decreased from 24.6 ± 4.2 to 9.0 ± 0.9 (P<0.01), and the visual analogue scale(VAS) score increased from 8.1 ± 0.9 to 82.5 ± 5.2 (P<0.01).

CONCLUSIONSNM is a clinically efficacious, minimally invasive and safe new technique, which offers an alternative treatment for the patients with intractable constipation resistant to conservative treatment, especially for the patients refractory to traditional operations.

PURPOSE: Data comparing the long-term efficacy and safety of subcutaneous immunotherapy (SCIT) using house dust mite (HDM) in children and adults with allergic rhinitis (AR) are limited. This study aimed to compare the long-term effects of HDM-SCIT in a cohort of Chinese pediatric and adult patients with AR. METHODS: A total of 124 pediatric and adult AR patients received HDM-SCIT for 3 years, with 118 patients being followed-up for 2 years. Prior to treatment (baseline), at the end of the 3-year treatment periods (third year) and 2 years after the discontinuation of treatment (fifth year), all patients were evaluated for total nasal symptom scores (TNSS), daily medication score (DMS), total combined score (TCS; symptoms [nasal + ocular] + DMS) and quality of life (QoL). Safety was assessed according to adverse events reported. RESULTS: After 3-year treatment, HDM-SCIT significantly improved symptoms and QoL scores at the end of the third and fifth years in both groups. Better improvements were observed in the third and fifth years based on baseline, in children compared to adults (TNSSΔ3: 6.66 vs. 5.41, P = 0.011; TCSΔ3: 4.30 vs. 3.83, P = 0.027 and TNSSΔ5: 6.16 vs. 4.86, P = 0.037; TCSΔ5: 4.11 vs. 3.62, P = 0.044).Shorter duration of AR history before SCIT (<10 vs. ≥10 years) resulted in better improvements at the end of the third and fifth years (TCSΔ3: 4.12 vs. 3.13, P = 0.036; TCSΔ5: 3.90 vs. 3.09, P = 0.033). HDM-SCIT was safe and comparable in both children and adults with AR. CONCLUSIONS: Children with AR may achieve better long-term efficacy of HDM-SCIT than adults with AR.
