  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

Objective To analyze the cancergene expression profile data using multi-support vector machine recursive feature elimination algorithm (MSVM-RFE) and calculate the genetic ranking score to obtain the optimal feature gene subset. Methods Gene expression profiles of bladder cancer, breast cancer, colon cancer and lung cancer were downloaded from GEO (Gene Expression Omnibus) database.The differentially expressed genes were obtained by differential expression analysis. The differential gene expressions were sequenced by MSVM-RFE algorithm and the average test errors of each gene subset were calculated. Then the optimal gene subsetsof four kinds of cancer were obtained according to the minimum average test errors. Based on the datasets of four kinds of cancer characteristic genes before and after screening, linear SVM classifiers were constructed and the classification efficiencies of the optimal feature gene subsets were verified. Results Using the optimal feature gene subsetobtained by MSVM-RFE algorithm, the classification accuracy was improved from (96.77±1.28)％to (99.85±0.46)％for the bladder cancer data, improved from (83.77±4.93)％to (88.30±3.85)％for the breast cancer data, and improved from (72.69±2.41)％to (90.21±3.31)％for the lung cancer data.Besides, theoptimal feature gene subsetkept the classification accuracy of colon cancer classifierat a high level (>99.5％). Conclusions The feature gene extraction based on MSVM-RFE algorithm can improve the classification efficiency of cancer.

Objective To Observe and evaluate the effect of hyperbaric oxygen therapy for patients with tracheotomy using ventilator lengthening tube. Methods 75 patients with tracheotomy in our hospital from January 2017 to January 2018 were divided into the study group (n = 38 cases) and the control group (n = 37 cases) according to the random number method. The control group used conventional oxygen inhalation while the study group used the ventilator tube after prolonged special oxygen hyperbaric oxygen pipe three (built-in ventilation pipe check valve) and bellows connecting an oxygen supply device, compared two groups of patients with oxygen inhalation methods suction phlegm oxygen concentration times and cabin, every time when treating. Results The rate of oxygen inhalation in the study group was 97. 37％ (37/38) higher than that of the control group (81. 08％ (30/37)), and the difference was statistically significant (P＜0. 05). The number of sputum sucking in the study group was (1. 02 ± 0. 36) times less than that of the control group (2. 32 ± 0. 53), and the difference was statistically significant (P＜0. 05). The total time of hospitalization in the study group was (16. 4 ± 2. 4) d, and the total time of hospitalization in the control group was (21. 7 ± 3. 2) d, the difference was statistically significant(WTBX〗P＜0. 05). The score of GCS in the study group was higher than that of the control group, and the difference was statistically significant (P＜0. 01). Conclusion The ventilator extension tube for hyperbaric oxygen therapy in patients with tracheotomy improves the oxygen concentration, ensures the curative effect, reduces the oxygen concentration in the cabin and reduces security risks; the operation method is safe, simple and practical and convenient for clinical application.

Huacao Community Health Service Center has established an integrated chronic kidney disease (CKD) management system since 2015,which greatly improved CKD management in the community.From September 2016 to August 2017,4084 residents were screened by the family doctor team,975 were suspected to have CKD (23.87％),among whom 202 (20.72％) were referred to district CKD treatment center,and 197 (97.52％) were confirmed as CKD.The detection rate of suspected CKD among patients with hypertension and diabetes mellitus was the highest,which was much higher than that among outpatients and those with routine health check up.It is suggested that the integrated management of CKD should be widely implemented to cope with the prevalence of CKD,particularly for those with hypertension and diabetes.

A total of 510 patients with type 2 diabetics mellitus (T2DM)from Huacao Township of Shanghai suburb were enrolled in the study. The gender, age, duration for diabetes, HbA1c level, blood pressure level, obesity status and health education of chronic kidney disease (CKD) were recorded. The knowledge, attitude and practice (AKP) of the subjects regarding prevention and treatment of CKD were assessed by using a self-restraint questionnaire. The data were analyzed with logistic regression. The knowledge awareness rate, attitude positive rate and behavior execution rate were 44.1％(225/510), 49.0％(250/510) and 16.5％(84/510), respectively. Scores of knowledge,attitude,behavior and medication compliance of the subjects were 16.8 ± 4.8, 18.3 ± 3.6 and 13.1 ± 4.1, respectively. The attitudes were closely related to educational level, HbA1c level, systolic blood pressure, obesity, health education history, and awareness level of CKD;behaviors were closely related to education level, systolic blood pressure, obesity, health education history and CKD prevention and treatment(P<0.05).

OBJECTIVETo provide prenatal diagnosis for two families affected with oculocutaneous albinism (OCA), in both of which only 1 pathogenic allele has been identified.

METHODSTo determine the clinical classification of OCA through DNA sequencing for TYR, P, TYRP1 and SLC45A2 genes in combination with phenotype analysis. Prenatal diagnosis was carried out by direct sequencing and intragenic SNPs family-based linkage analysis.

RESULTSIn the first family, only 1 heterozygous mutation c.1255C>T was found in the proband, which was inherited from her mother. Together with its clinical phenotype, the proband was suspected to have OCA2 Screening of amniotic fluid, however, has found no mutation. With family-based linkage analysis, the fetus was deemed to be an OCA2 carrier. In the second family, again only one heterozygous mutation c.1920_1949 del30bp and ins AACA was found in the proband, which was inherited from her father. Together with its clinical phenotype, the proband was suspected to have OCA2. Screening of amniotic fluid has revealed a heterozygous mutation c.1920_1949 del30bp and ins AACA. By family-based linkage analysis, the fetus was deemed to be an OCA2 carrier. Both fetuses had a normal phenotype at birth.

CONCLUSIONPrenatal genetic diagnosis has been provided for the first time for two families affected with OCA, in which only 1 pathogenic mutant allele was detected. The combined mutation detection and SNPs linkage analysis has turned out to be successful.

OBJECTIVETo determine the genotype of a family affected with oculocutaneous albinism (OCA) and to provide genetic counseling and prenatal diagnosis.

METHODSTo determine the genotypes and mutational sites through PCR and sequencing for all exons and exon-intron junctions of 4 OCA genes in the proband and the P gene of her parents. Prenatal genotyping of the fetus was carried out using amniocentesis sample.

RESULTSThe patient was diagnosed with OCA2 based on a genotype of c.1327G>A/c.2360C>T. Her father was heterozygous for c.2360C> T, whilst her mother has none of the two mutations. c.1327G>A is therefore a maternal de novo mutation. Neither of the mutations was found in the fetus.

CONCLUSIONA maternally inherited de novo mutation c.1327G>A has been identified in the patient. In order to detect de novo mutations, full sequence analysis is necessary.
