Objective:To optimize the culture system for the mesenchymal stem cells from the Placenta Chorion (hCMSC) in vitro by adding the selected cytokines to amplify the hCMSC effectively,with furthermore some preliminary analysis of the hCMSC performed.Methods:Immunohistochemistry was applied to show the localization of the mesenchymal stem cells within the placenta chorion,then the corresponding part of chorion was digested by collagenase Ⅳ to get the cell suspension for primary culture and subculture;Flow Cytometry was used to detect the surface marker of hCMSC,whose proliferation was detected by direct cell counting and the MTT method;then Butylated Hydroxyanisole (BHA),and DMSO was used combinedly as the inducer in the differentiation of the hCMSC to the neuron like cells,which was then detected by Immunofluorescence staining for the expression of NSE;finally RT-PCR was used to detect the expression of flt3.Results:The result of immunohistochemistry showed CD105~-,CD90~- positive hCMSC was much easier to be found around the blood vessels within the villous of chorion,which then could be obtained by mechanical dissociation and collagenase digestion.bFGF was good at amplifying the hCMSC among all selected cytokines,but FL was showed even obviously effective on the proliferation of the hCMSC.The propagating cells were found to highly express CD73,CD90,CD105;and negative for CD14,CD34,CD45 and HLA-DR.We also found that the hCMSC happened to express PDL-1 the negative co-stimulatory molecules,while their potential to different into the neuron like cells was still well maintained.Conclusion::There is low immunogenicity mesenchymal stem cells within the placenta chorion,both bFGF,FL are shown good effects on the proliferation of the hCMSC,with maintaining their differentiation potential as well.

Objective To explore the characteristics of diagnosis and treatment of Behset's disease (BD) with meningeal thickening and to improve doctors" awareness of such diseases.Methods We reported a missed diagnosis of a patient with BD complicated with diffuse meningeal thickening,and reviewed the related literature.Results A 25-year-old young man,manifested mainly as recurrent headache,fever,recurrent oral ulcer,erythema skin nodules and folliculitis,and his cranial radiology revealed diffuse meningeal thickening and intracranial venous sinus thrombosis.We diagnosed him as neuropathy associated with BD.After the treatment with steroids,cyclophosphamide,infliximab and anti-coagulants,his symptoms improved rapidly.Conclusion In clinical,BD complicated with meningeal thickening is rare,which is easily misdiagnosed or miss-diagnosed.For the patients with unexplained meningeal thickening,the symptoms of BD,such as recurrent oral or genital ulcers,ophthalmitis and skin lesions,should be acquired in detail.In addition to steroids and immunosuppressive agents,anti tumor necrosis factor (TNF)-alpha can also be used in the treatment of BD with meningeal thickening.

Objective To evaluate the effect of an emollient containing Prinsepia utilis Royle oil extracts and other extracts on clinical symptoms and disease recurrence in children aged 2-12 years with atopic dermatitis (AD) in the remission period.Methods A multicenter,randomized,parallel-group,controlled clinical trial was conducted from December 2017 to September 2018.A total of 297 children aged 2-12 years with moderate AD were enrolled from 5 hospitals in China,and randomly divided into the test group (148 cases) and control group (149 cases).In the acute stage,the two groups were both topically treated with mometasone furoate cream once a day on the skin lesions,and with an emollient containing Prinsepia utilis Royle oil extracts and other extracts twice a day throughout the whole body for 2-4 weeks.The children would be enrolled into the remission stage if their Investigator's Global Assessment (IGA) score was ≤ 1 at following visits.In the remission stage,the test group was only topically treated with the emollient twice a day throughout the whole body,while mometasone furoate cream and the emollient were both withdrawn in the control group.At weeks 4,8 and 12 in the remission stage,the recurrence of AD,eczema area and severity index (EASI),children's dermatology life quality index (CDQOL) and adverse events were evaluated.Statistical analysis was carried out with SAS 9.4 software by using t test for comparison of normally distributed continuous data between two groups,chi-square test for comparison of unordered categorical data,Kaplan-Meier method for analysis of survival rates,Cox regression analysis for evaluating the effect of different therapies on AD recurrence in children in the remission stage,and Logistic regression analysis for analysis of odds ratio (OR) of EASI or CDQOL at week 4 in the remission stage between the test group and control group.Results Of the 297 children with AD,31 breached the clinical trial protocol,and 266 were included in the per protocol set (PPS),including 132 in the test group and 134 in the control group.In the PPS,114 and 106 patients completed the follow-up in the test group and control group respectively,and the recurrence rate was significantly lower in the test group (47,41.23％) than in the control group (84,79.25％;x2 =32.96,P ＜ 0.001).The time to recurrence was significantly longer in the test group(61.99 d ± 2.80 d)than in the control group(39.17 d ± 2.54 d,t =6.03,P ＜ 0.001),and the recurrence risk was significantly lower in the test group than in the control group (Log rank test,x2 =32.02,P ＜ 0.001).After adjustment for age and gender,Cox regression analysis showed that the recurrence risk in the test group was 0.35 times that in the control group (HR =0.35,95％ CI:0.24-0.51,P ＜ 0.01).At week 4 in the remission stage,the EASI score at P50-P75 and P75-P100 in the test group were 0.42,0.25 times that in the control group respectively (95％ CI:0.20-0.86,0.12-0.54 respectively;P =0.02,＜ 0.01respectively).Moreover,the CDQOL score at P75-P100 in the test group was 0.33 times that in the control group (95％ CI:0.17-0.65,P ＜ 0.01).No significant difference in the incidence of adverse events was observed between the two groups (P ＞ 0.05).Conclusion Maintenance treatment with the emollient containing Prinsepia utilis Royle oil extracts and other extracts can markedly reduce the recurrence risk in AD children,improve clinical symptoms,and enhance the quality of life.

2019 novel coronavirus(2019-nCoV) outbreak is one of the public health emergency of international concern.Since the 2019-nCoV outbreak, China has been adopting strict prevention and control measures, and has achieved remarkable results in the initial stage of prevention and control.However, some imported cases and sporadic regional cases have been found, and even short-term regional epidemics have occurred, indicating that the preventing and control against the epidemic remains grim.With the change of the incidence proportion and the number of cases in children under 18 years old, some new special symptoms and complications have appeared in children patients.In addition, with the occurrence of virus mutation, it has not only attracted attention from all parties, but also proposed a new topic for the prevention and treatment of 2019-nCoV infection in children of China.Based on the second edition, the present consensus further summarizes the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of treatment of 2019-nCoV infection in children.

Objective:To systematically review the efficacy of preoperative corticosteroids use as an adjunctive treatment for rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD).Methods:A evidence-based medicine study. The National Library of Medicine's PubMed, Web of Science, CNKI, and WanFang database were searched. Clinical controlled studies were selected the study object was RRDCD patients and the interventions were preoperative corticosteroids used as an adjunctive treatment. The search was conducted from January 2000 to January 2022. Duplicated, incomplete, or irrelevant articles were excluded. The conventional meta-analysis was used to evaluate the efficacy of corticosteroids used before surgery. The network meta-analysis was used to directly or indirectly compare the efficacy of oral corticosteroids or intravenous dexamethasone, peribulbar injection of glucocorticoids, prednisolone acetate eye-drops, intravitreal injection of triamcinolone acetonide (TA) and posterior sub-tenon injection of triamcinolone acetonide. Publication bias was evaluated by funnel plot.Results:According to the search strategy, 43 articles were initially retrieved, and 929 eyes of 13 articles were finally included for analysis; 6 and 10 articles were included in the traditional meta-analysis and the network meta-analysis. Among the 6 studies included in the conventional meta-analysis, 5 studies were retrospective and 1 study was a randomized controlled trial, involving a total of 575 eyes. The analysis results showed that there was no significant difference in the primary retinal reattachment rate between the corticosteroids group and the control group [odds ratio ( OR)= 1.53, 95% confidence interval ( CI) 0.67-3.53, P=0.314]. Among the 10 studies included in the network meta-analysis, 7 studies were retrospective trials, 2 studies were randomized controlled trials, and 1 study was prospective trial, involving a total of 575 eyes. The analysis results showed that there were significant differences in the primary retinal reattachment rate between the triamcinolone acetonide intravitreal injection group and the no corticosteroid treatment group ( OR=4.09, 95% CI 1.06-15.79). Sub-tenon injection triamcinolone acetonide had a higher incidence rate of ocular hypertension than oral glucocorticoid or intravenous dexamethasone ( OR= 4.47, 95% CI 1.42-14.13). Conclusions:Triamcinolone acetonide intravitreal injection before surgery can improve the primary retinal reattachment rate in RRDCD patients. Patients with the posterior sub-tenon injection of triamcinolone acetonide should be alert to elevated intraocular pressure.

Objective:To observe the correlation between blood cell-related inflammatory markers and diabetic retinopathy (DR).Methods:A cross-sectional study. From June 2020 to February 2022, the phase Ⅰ data of Beichen Eye Study in Tianjin Medical University Eye Hospital were included in the study. The research contents included questionnaires, routine systemic and ocular examinations, and laboratory blood cell-related indicators including mean platelet volume (MPV), platelet distribution width (PDW), neutrophils, and lymphocytes were performed. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) were calculated. The diagnosis and classification of DR referred to the international clinical classification standard of DR. Monocular or binocular DR was defined as DR patients. Participants were categorized into different groups based on whether they had diabetes and whether they had DR. The groups included the no-diabetes group, the diabetes without DR group, and the DR group. The Kruskal-Wallis H test was used for the comparison of quantitative data among multiple groups. Wilcoxon test was used for comparison between the two groups. The χ2 test was used to compare the categorical variables between groups. The variables was adjusted step by step, an unadjusted univariate model was built and the different parameters of the model Ⅰ, Ⅱ, Ⅲ were adjusted. The correlation between MPV, PDW, NLR, PLR, and DR in different models was analyzed by logistic regression. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficacy of different NLR models for DR. Results:A total of 3 328 subjects were recruited. Among them, 1 121 (33.68 %, 1 121/3 328) were males and 2 207 (66.32 %, 2 207/3 328) were females. The median age of the included participants was 61.84 (6.05) years. The no-diabetes group, the diabetes without DR group, and the DR group were 2 679, 476, and 173, respectively. There was no significant difference in MPV and PLR among the three groups ( H=5.98, 1.94; P=0.051, 0.379). However, compared with no-diabetes group and the diabetes without DR group, PDW and NLR in the DR group showed an upward trend. In model Ⅲ with completely adjusted related factors, NLR was an independent risk factor for DR in no-diabetes group and DR group [odds ratio ( OR)=1.440, 95% confidence interval ( CI) 1.087-1.920, P=0.041], diabetes without DR group and DR group [ OR=1.990, 95% CI 1.440-2.749, P<0.001]. The results of ROC curve analysis showed that the diagnostic efficiency of NLR model Ⅲ was the highest, the area under the curve was 0.751 (95% CI 0.706-0.796, P<0.001), the optimal cutoff value was 0.390, and the sensitivity and specificity were 74.3% and 64.8%, respectively. Conclusions:The NLR of the DR group is significantly higher than that of the no-diabetes group and diabetes without DR group. NLR is an independent risk factor for DR.
