It is known that patients with vitiligo often have antibodies to melanocytes. In order to identify vitiligo antibodies react to corresponding antigens, we used cultured normal human melanocytes to react with sera from 48 patients with vitiligo, the result showed that 52% of patients with vitiligo have antibodies to cell-surface antigens of melanocytes. Then immunoprecipitation and SDS-PAGE analysis were used to reveal molecular weights (MW) of the antigens, the result showed that the MW are about 75 000, 90 000, 110 000, and 150 000.

Objective To review and summarize the latest development of the therapy for the Duchenne muscular dystrophy (DMD). Methods The recently-published articles related to the therapies for DMD were extensively reviewed and briefly summarized. Results The therapeutic approaches for DMD included the gene therapy, the cell therapy, and the pharmacological therapy.The gene therapy and the cell therapy were focused on the treatment for the cause of DMD by the delivery of the missing gene, the modification of the mutated gene, and the transfer of the normal cells including the stem cells, while the pharmacological therapy dealt with the downstream events caused by the dystrophin gene defect, slowed down the pathologic progress of DMD, and improved the DMD patient's life quality and life span, by medication and other factor treatments. Conclusion There is still no cure for DMD because of various difficulties in replacing or repairing the defected gene and of the multifaceted nature of the severe symptoms. Therefore, it is imperative for us to find out a more effective treatment that can solve these problems.

Objective To explore the effects of perinatal infection on retinopathy of prematurity (ROP).Methods A retrospective cohort study was performed to analyzed the clinical data of 238 preterm infants at gestational age ≤32 weeks who were delivered in Guangdong Women and Children Hospital from November 2014 to October 2015 and ROP screening examinations.Observation was not terminated until they were 45 weeks of corrected gestational age.Mild ROP was defined as having stage 1 or stage 2 ROP in zone Ⅱ or Ⅲ without additional disease,and severe ROP was defined as stage 3 or higher,any ROP in zone Ⅰ,prethreshold/threshold,with additional disease,and aggressive posterior retinopathy of prematurity (AP-ROP).Medical records of eligible preterm infants were retrospectively reviewed and analyzed.Occurrences of ROP,severe ROP,and clinically significant ROP requiring surgical treatment were assessed.Results The mean gestational age of the cohort was (30.10 ± 1.34) weeks (25.29-32.00 weeks) and the mean birth weight was (1 373 ± 272) g(720 ～2 330 g).ROP was diagnosed in 76 of 238 infants (31.9％),including 39 cases with mild ROP (16.4％) and 37 cases with severe ROP (15.5％).Surgical treatment was performed on 22 infants (9.2％).In the patients with ROP,the time to develop ROP from birth was (35.16 ± 14.26) d and the mean time of its most serious stage was (44.62 ± 18.99) d.In 22 patients with ROP who required surgical treatment,the time of surgical treatment was (50.27 ± 17.24) d.In univariate analysis,maternal perinatal infection disease was found to be associated with ROP occurrence (x2 =7.891,P =0.005) and ROP progression requiring surgical treatment (x2 =4.494,P =0.034).Small gestational age,low birth weight and long-term oxygen therapy were found to be asso ciated with ROP occurrence and severe ROP (gestational age:t =-5.803,P ＜ 0.001;t =-5.290,P ＜ 0.001;t =-4.150,P ＜ 0.001;birth weight:t =-4.942,P ＜ 0.001;t =-4.058,P ＜ 0.001;t =-3.126,P =0.002;the duration of oxygen therapy:t =2.351,P =0.020;t =2.473,P =0.018).Apgar scores ≤ 7 at 1 min and 5 min were found to be associated with severe ROP (x2 =4.803,P =0.028).Neonatal sepsis and neonatal fungal infection were found to be associated with ROP occurrence (x2 =6.071,P =0.014;x2 =4.070,P =0.044).Neonatal fungal infection was also found to be associated with severe ROP (x2 =5.479,P =0.019).Multivariate regression analysis indicated that maternal perinatal infection disease was associated with an increased risk of ROP and ROP progression requiring surgical treatment (OR =2.837,P =0.023;OR =4.087,P =0.012).Maternal preeclampsia was also associated with an increased risk of ROP (OR =2.506,P =0.040).Gestational age was an important risk factor for the development of ROP.The smaller the gestational age was,the higher the rate of occurring ROP and severe ROP (OR =0.518,0.508,0.520,all P ＜ 0.001).Conclusions Both fetal and neonatal exposure to infection appear to contribute to the increase of ROP risk in the preterm infants at gestational age ≤ 32 weeks.Maternal perinatal infection disease and maternal preeclampsia were independently associated with ROP occurrence and ROP progression in the preterm infants at gestational age ≤32 weeks.

Objective To explore the influence of fixed-foot stance Yunshou combined with raising handclasp of Bobath on the recovery of upper extremity in post- stroke patients with hemiplegia. Methods Meeting the criteria 59 cases of stroke patients with hemiplegia were randomly divided into experimental group (29 cases) and control group(30 cases) according to random number table.All the patients in both groups were received routine therapy and nursing,besides,the patients in the control group were given raising handclasp of Bobath,while the patients in experimental group were treated with fixed-foot stance Yunshou combined with raising handclasp of Bobath.The intervention were once a day,five days a week,lasting eight weeks.The Fugl-Meyer Assessment of Upper Extremity(FMA-UE)and Modified Barthel Index(MBI) as well as Simple Test for Evaluating Hand Function(STEF) were used to assess the patients′condition before,8 weeks after treatment respectively. Results After 8weeks intervention,the scores of FMA-UE,MBI,STEF were 40.69±8.67,76.89±1.79,59.31±7.89 and before intervention were 24.17 ± 11.98,57.14 ± 13.93,31.83 ± 5.41, the difference between the experimental group before and after intervention was statistically significant(t=13.222,8.755,18.311,P<0.01).At 8 weeks,the scores of FMA-UE, MBI, STEF in the control group were 35.47 ± 9.68,73.17 ± 2.82,49.47 ± 8.78, and were17.38 ± 4.10,37.38 ± 4.30, 74.62 ± 11.22 respectively before intervention,all the measures in control groups had significantly improved than those before training (t=-4.797, 7.372, 17.139, P<0.01).Score of FMA-UE and STEF in the experimental group were higher than those in the control group,and the difference was statistically significant (t=2.180, 4.525, P<0.05 or 0.01), while the MBI had no statistically difference between two groups (P>0.05). Conclusion Compared with training on raising handclasp of Bobath alone,fixed-foot stance Yunshou combined with raising handclasp of Bobath is more effective On the recovery of upper limb function in stroke patients with hemiplegia.

OBJECTIVETo investigate the clinical and genetic characteristics of three Chinese Meniere's disease (MD) families and decipher the mechanism of MD further.

METHODSPersonal and family medical evidence of hearing loss, vestibular symptoms, and other clinical abnormalities of the participants were identified, clinical and genetic features were analyzed. Targeted 307 genes capture and high-throughput sequencing were performed on the two ascertained members of family 1007184.

RESULTSEight patients from these three families showed post-lingual sensorineural hearing loss, six women and two men were involved. Age of onset in these affected members concentrated in the middle age, with the average age of 39.3 years old. Among them, patients from 1407278 were accompanied by migraine. All of the three probands presented as recurrent vertigo firstly, and then fluctuated hearing loss showed up, accompanying by tinnitus and ear fullness feeling. The hearing loss manifested as late-onset, low frequency-involved pattern, with subsequent gradual progression from moderate to severe level. Some of the patients progressed to severe level involving all frequencies at higher ages. In addition, most of the cases showed revitalization. Four cases received vestibular function tests, three of which had varying dysfunction of vestibular function, while the other one had normal vestibular function. Patients who had abnormal vestibular function showed much more severe hearing impairment. The three-generation family 1007193 had an autosomal recessive genetic characteristics, family 1007184 showed autosomal dominant inheritance of characteristics, family 1407278 were either autosomal dominant or X-linked dominant pattern. Through target genes capture high-throughput sequencing technology, we identified two candidate variants in the two members of family 1007184, named c. 2057G>A in EGFLAM and c. 1961C>T in ITGA8.

CONCLUSIONMeniere's disease has some genetic and familial aggregation in Chinese population, but its complex genetic pathogenic mechanisms need further study.

AIM: To compare the efficacy of intravitreal injection of ranibizumab(IVR)and intravitreal injection of conbercept(IVC)in children with retinopathy of prematurity(ROP).METHODS: Retrospective study. A total of 1 100 eyes with ROP treated with intravitreal anti-VEGF at our hospital from January 2015 to June 2023 were included. According to the different therapeutic drugs, the children were divided into two groups: IVR group and IVC group. According to the degree of ROP, the patients were divided into three groups: aggressive ROP(A-ROP), Zone Ⅰ type 1 ROP and Zone Ⅱ type 1 ROP. The reactivation and retreatment between the two groups were compared after propensity score matching(PSM)analysis, and they were followed-up for at least 3 mo after surgery.RESULTS: In Zone Ⅱ type 1 ROP, there was a statistically significant difference in the rates of reactivation and retreatment between the IVR and IVC groups(P<0.05); however, in A-ROP and Zone I type 1 ROP, there were no statistically significant differences in the rates of reactivation and retreatment between the two groups(P>0.05). The risk of reactivation and retreatment of Zone I type 1 ROP was higher than the Zone II type 1 ROP. Furthermore, the use of drugs and corrected gestational age of first treatment were influencing factors of lesion recurrence and retreatment.CONCLUSION: There is a significant difference in the initial cure effect between the two drugs in Zone II type 1 ROP, with the reactivation and retreatment rates of the IVC group being much lower than those of the IVR group.
