Objective:To compare the clinical data and peripheral blood levels of CXC chemokine ligand (CXCL) 9 and CXCL10 between patients with progressive non-segmental vitiligo who were sensitive to systemic glucocorticoid treatment and those who were resistant, and to clarify key clinical factors influencing the sensitivity to systemic glucocorticoid treatment.Methods:From May 2021 to May 2023, a cohort of patients with progressive non-segmental vitiligo receiving systemic glucocorticoid treatment was established in Huashan Hospital, Fudan University. Clinical data and peripheral blood samples were prospectively collected from all enrolled patients. Standard treatment, i.e., intramuscular injections of 1 ml of compound betamethasone once a month, was administered. After 3-month treatment, the improvement of patients′ skin lesions was estimated, and the vitiligo area and severity index (VASI) score and the Vitiligo European Task Force assessment tool (VETFa) were used to evaluate the efficacy. Patients with VASI changes ≥ 0 and VETFa progression scores ≤ 0 point were included in the glucocorticoid-sensitive group (i.e., the patients′ condition was stable or improved), otherwise those with VASI changes < 0 and VETFa progression scores of 1 point were included in the glucocorticoid-resistant group. Associations of lesion locations, specific clinical markers (trichrome lesions, confetti-like depigmentation, and Koebner phenomenon), previous medication history, family history of vitiligo, etc. with the response to systemic glucocorticoid treatment were analyzed. At baseline and after 3-month treatment, peripheral blood samples were collected from the patients, and enzyme-linked immunosorbent assay was performed to detect the plasma levels of CXCL9 and CXCL10. Statistical analysis was carried out by using the chi-square test, Fisher′s exact test, binary logistic regression analysis, Mann-Whitney U test, and Wilcoxon signed-rank test. Results:A total of 142 patients with vitiligo were enrolled, and 127 completed 3-month treatment, including 77 males and 50 females. Their age at diagnosis was 18 to 65 (36.6 ± 11.4) years, and the disease duration ranged from 2 months to 58 (13.5 ± 10.7) years; 25 (19.7%) had a family history of vitiligo; the percentage of lesion area to total body surface area before treatment ranged from 1% to 70% (11.5% ± 12.7%), and the VASI score was 1% to 70% (10.8% ± 11.6%). Multivariate logistic regression analysis showed that the absence of specific clinical markers (odds ratio [ OR] = 6.900, 95% confidence interval [ CI]: 1.228, 38.757, P = 0.028), carrying a single specific clinical marker ( OR = 2.579, 95% CI: 1.012, 6.574, P = 0.047), having a history of topical glucocorticoid treatment ( OR = 2.643, 95% CI: 1.019, 6.850, P = 0.041), the absence of family history of vitiligo ( OR = 5.090, 95% CI: 1.070, 24.215, P = 0.030), and lesions on the proximal extremities ( OR = 3.767, 95% CI: 1.315, 10.793, P = 0.037) were risk factors for the resistance to systemic glucocorticoid treatment in the patients with vitiligo. After 3-month treatment, the glucocorticoid-sensitive group showed a significant decrease in plasma CXCL10 levels compared with those before treatment ( W = 571.00, P < 0.001), while there was no significant difference between the pre- and post-treatment CXCL10 levels in the glucocorticoid-resistant group ( W = 48.00, P = 0.524). Additionally, no significant difference was observed in changes of the plasma CXCL9 level before and after treatment between the glucocorticoid-sensitive and glucocorticoid-resistant groups ( P > 0.05) . Conclusions:Carrying no or a single specific clinical marker, having a history of topical glucocorticoid treatment, the absence of family history of vitiligo, and lesions on the proximal extremities appeared to be risk factors for the resistance to systemic glucocorticoid treatment in patients with progressive non-segmental vitiligo. Changes in CXCL10 levels after treatment may be used as an important evaluation indicator for determining whether patients with progressive vitiligo were resistant to systemic glucocorticoid treatment.

Objective:To summarize the clinical and genetic characteristics of early-onset spinocerebellar ataxia type 5 (SCA5) caused by SPTBN2 gene mutation. Methods:The clinical and genetic data of a child with early-onset SCA5 diagnosed in the Department of Children′s Rehabilitation, Women and Children′s Hospital Affiliated to Qingdao University in February 2022 were retrospectively analyzed. The literatures related to early-onset SCA5 in major databases at home and abroad were retrieved and summarized.Results:The patient, a 4 years and 1 month old girl, was admitted to hospital because of "unable to stand independently at 2 years and 3 months", primarily presented with developmental delay, ataxia, hypotonia, and tendon hyperreflexia during infancy. Progressive cerebellar atrophy was observed on brain magnetic resonance imaging. A de novo heterozygous mutation of the SPTBN2 c.793G>C(p.Asp265His) was identified in the patient. Following hospitalization, the child received comprehensive rehabilitation therapy encompassing physical, occupational, language, educational interventions as well as bicycle ergometer training and transcranial magnetic stimulation. The patient was followed-up for more than 1 year to 4 years and 1 month old, whose motor function, cognitive abilities, and language skills were improved to some extent. A total of 13 English articles and 1 Chinese article were retrieved from the databases. A total of 20 early-onset SCA5 patients have been reported, with onset ages all within 12 months. Infants exhibited decreased muscle tone and delayed motor milestones, with the main clinical manifestations of ataxia, generalized developmental delay, and cerebellar atrophy. The previously reported cases involved 11 mutation sites in the SPTBN2 gene, and the main types of mutations were de novo missense mutations. The mutation site in this case has not been reported in the previous literature. Conclusions:Early-onset SCA5 is a rare autosomal dominant disorder caused by heterozygous mutations in the SPTBN2 gene. The main clinical manifestations include ataxia from infancy, developmental retardation and cerebellar atrophy. Early rehabilitation intervention can improve the degree of the dysfunction.

Objective: To investigate the clinical efficacy and safety of soluble hyaluronic acid microneedle eye patch on infraorbital wrinkles. Methods: Seventy-five female subjects in Beijing and Shanghai were recruited and treated with soluble hyaluronic acid microneedle patch two days a week at the left lower eyelid (experimental side) and at least 30 minutes each time for 12 weeks. Investigator visual assessment, instrumentation measurement for skin moisture, elasticity, wrinkle area and depth were performed at week 0 (pre-treatment) and week 4 and week 12 and compared to the right (control side). The safety was assessed by documenting adverse reactions occurring during the study. Subject satisfaction was assessed at week 12. Results: After 12 weeks of treatment, the visual assessment of skin wrinkles on experimental side (n=41, 54.67%) was significantly improved as comparied with that on control side (n=14, 18.67%). The skin hydration of treatment side skin increased with treatment time (t=-0.488 at week4, t=-3.054 at week 12, P<0.05). After 12 weeks of treatment, skin elasticity of the experimental side improved significantly. The improvement rate of the experimental side was more than that of the control side (t=2.724, P<0.05). The wrinkle area was significantly decreased in 4 and 12 weeks compared with pre-treatment (t=4.442 at week 4 and t=3.802 at week 12, P<0.001). The depth of wrinkles of the experimental side shallowed with the treatment (t=-2.435 at week 4 and t=-3.433 at week 12, P<0.05). Only 8% (n=6) of the subjects had temporary slight pruritus or acupuncture sensation on the treatment side, and no other adverse reactions occurred. The overall subject satisfaction rate was 88%(n=66). Conclusions Soluble hyaluronic acid microneedle eye patch is effective in improving wrinkles, skin elasticity and hydrating, and has no obvious adverse reaction.

BACKGROUND: Vitiligo is a common acquired pigmentary disease caused by destruction of epidermal melanocytes in underlying autoimmune response. Few studies have been focused on the role of chemokines in non-segmental vitiligo (NSV) concomitant with autoimmune thyroid disease (AITD) and alopecia areata (AA). OBJECTIVE: The aim of this study was to determine the best serum biomarker for predictive role in the progression of vitiligo and to evaluate the influence of AA and/or AITD on vitiligo by using the biomarker. METHODS: This prospective cohort study recruited 45 NSV patients: 14 without either AITD or AA, 12 with AITD, 11 with AA, and 8 with both AITD and AA. Serum levels of CXCL1, CXCL8, CXCL9, CXCL10, CXCL12, CXCL13, and CXCL16 were analyzed by ELISA. CXCR3 mRNA expression was detected on PBMCs by RT-PCR. Improvement was evaluated using repigmentation scales. RESULTS: Serum CXCL10 levels, along with the expression of CXCR3 mRNA were higher in NSV patients with AITD or AA alone than in those without AITD or AA. Moreover, serum CXCL10 levels, along with the expression of CXCR3 mRNA were higher in NSV patients with both AITD and AA than in those with AITD or AA alone. Poorer repigmentation was observed in NSV patients with both AA and AITD than in those with AA or AITD alone. CONCLUSION: CXCL10 could be a biomarker to predict the progression of NSV. Dermatologists should pay much attention to those NSV patients concomitant with AITD and/or AA, for comorbidity might lead to more active autoimmune reaction.

BACKGROUND: Severe cutaneous adverse reactions (SCAR) to drugs are a crucial public health issue and the use of systemic corticosteroids in SCAR has been controversial. OBJECTIVE: To analyze clinical features, causative drugs, treatment, outcomes, and prognostic factors of SCAR in the case-series of 173 patients, and add more information to the debate of using systemic corticosteroids in SCAR management. METHODS: A retrospective study of 173 SCAR patients diagnosed with drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) or acute generalized exanthematous pustulosis (AGEP) at a tertiary care institution in China between January 2014 and December 2017 was conducted. RESULTS: Of 173 patients, allopurinol, carbamazepine, and antibiotics are the most frequently implicated drugs for DRESS (40.4%), SJS/TEN (26.0%), and AGEP (40.0%) respectively. Moreover, there is a strongly negative correlation between early corticosteroids use and the progression (p=0.000) and severity (p=0.01) of skin lesions. However, there is no association between early corticosteroids use and the mortality of SCAR (odds ratio: 1.01, 95% confidence interval: 0.95~1.08). In addition, lymphadenopathy, eosinophilia, and interval from onset to corticosteroids treatment were correlated with SCAR prognosis. CONCLUSION: Prompt short-course systemic corticosteroids use is associated with early-stage skin lesions remission without influencing the disease mortality. Lymphadenopathy and eosinophilia were the independent poor prognostic factors of SCAR.

Infantile spasms (IS) is an age dependent epileptic encephalopathy in early infancy. Early diagnosis and treatment (within 4 weeks of onset) are beneficial to the termination of seizures and long-term cognitive protection. This paper reviewed the related literatures in the treatment of infantile spasms, mainly including the first-line and second-line drugs, the ketogenic diet and surgical treatment, to discuss the recent advances in the treatment of infantile spasms.

Objective To investigate the correlation factors for surgical outcome of sacral decompression and lumbopelvic fixation in H-shaped sacral fracture and the methods to prevent and treat the complications.Methods From January 2008 to January 2016,45 patients with H-shaped sacral fracture treated by sacral decompression and lumbopelvic fixation were respectively analyzed,including 29 men and 16 women,mean age 41.2 (range,24-53 years),mean follow-up time 52.6 months (range,16-93 months).The surgical outcome was evaluated by pelvic outcome score,and correlation factors were analyzed.We analyzed whether each factor was in correlation with pelvic outcome score.Then we integrated the statistically significant indicators into Logistic regression equation to determine the related factors.Postoperative complications were all recorded.Results The average operation time was 161.2 min (range,100-220 min),average blood loss was 491.6 ml (range,370-1 000 ml),injury-surgery interval was 7.2 d (range,1-23 d).In terms of pelvic outcome score,31 (68.9％) patients had satisfactory result and 14 (31.3％) patients had unsatisfactory result.Univariate x2 analysis suggested that cauda equina injury,Roy-Camille classification,L5S1 facet injury,fracture line,kyphotic angle,injury-surgery interval,decompression approach and inserting sacral screws were correlated with pelvic outcome score,but gender,age,injury mechanism and L5 pedicle fracture had no relation with pelvic outcome score.The multivariate Logistic regression analysis showed that cauda equina injury,Roy-Camille classification,fracture line,kyphotic angle,injury-surgery interval,decompression approach and inserting sacral screws were closely related to pelvic outcome score,but L5S1 facet injury was excluded.2 patients required early surgical procedures with proper antibiotics for deep wound infection;3 patients complained pain related to hardware prominence and the pain subsided after removal of implants;1 patient got unilateral rod breakage at 3-6 months and achieved bony fusion after nine months of observation.Conclusion Sacral decompression and lumbopelvic fixation is effective in neurological recovery and early ambulation in treating H-shaped sacral fracture.Better surgical outcome is related to timely surgery,preoperative or intraoperative bone traction,sacral screws insertion,incomplete cauda equina injury,Roy-Camille type Ⅱ,fracture line penetrating S2 and kyphotic angle less than 40°.

OBJECTIVETo discover and interpret the correlations between traditional Chinese medicine (TCM) slices and their properties such as function, symptom and channel tropism by constructing the relationship network using network pharmacology approaches.

METHODTCM slices related information was extracted from Chinese Pharmacopeia (2010 edition, volume I) by text mining, and was used to construct the TCM slices-symptom relationship network. The corresponding network analysis was also performed.

RESULTThree thousands and sixteen pair of TCM slice-symptom correlation associated with 646 TCM slices was discovered, and the constructed network unfolded the complex relationships between TCM slices. Further network analysis results indicated that the un-annotated function and channel tropism of TCM slice can be revealed by proposed symptom-based network.

CONCLUSIONNetwork pharmacology approaches can be applied in TCM research to discover and interpret the relationships between TCM slices and their properties.
