OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.

METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.

RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.

CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

Andrographolide total ester sulfonate (ATES) injection is one of the products of traditional Chinese medicine (TCM) currently used against viral infection in China.ATES injection was approved for manufacturing and marketing in January 2002.It is indicated for acute respiratory infections,tonsillitis,chronic obstructive pulmonary disease,influenza,foot and mouth disease,bronchiolitis,herpangina,mumps,infectious mononucleosis and psychosis.However,its usage also carries risk.We investigated the use of ATES at the Wuhan Union Hospital from January 2014 to December 2014 and evaluated its real-word clinical application using the hospital centralized monitoring method.A total of 848 cases were enrolled in this study.In these cases,it was mainly used for postoperative anti-inflammation and treating upper respiratory infection,pneumonia and bronchitis.Among them,39.86％ were contraindicated.Irregular medication of adults and children accounted for 1.91％ and 23.38％,respectively.Improper choice of solvent accounted for 3.18％.The choice of intravenous drip versus aerosol inhalation was reasonable.A case of adverse events (AEs) was observed in the monitoring period,and the incidence of adverse drug reaction (ADR) of ATES injection was 0.12％.ATES injection in our hospital is relatively safe with a low incidence of adverse reactions.The study assesses the clinical usage and adverse reactions of ATES injection,and provides suggestions for rational use in clinical practice.

Objective To detect the expression of BRAF V600E mutant protein in cutaneous malignant melanoma (CMM),and to evaluate the sensitivity and specificity of immunohistochemistry (IHC) in detecting BRAF V600E mutation.Methods IHC with an anti-BRAF V600E monoclonal antibody was performed to detect the expression of BRAF V600E mutant protein in paraffin-embedded tissue sections from 103 patients with CMM and 40 patients with nevus.Statistical analysis was carried out with SPSS software version 17.0,and the expression rate of BRAF V600E mutant protein was compared by chi-square test.Results The expression rate of BRAF V600E mutant protein in the CMM patients was 20.4％ (21/103),significantly higher than that in the nevus patients (5.0％ (2/40),x2 =5.06,P ＜ 0.05).Significant differences were observed in the expression rate of BRAF V600E mutant protein between CMM patients of different age groups (29.8％ (14/47) in patients aged ＜ 60 years vs.12.5％ (7/56) in those aged ≥ 60 years,P ＜ 0.05) and nationality (30.2％ (13/43) for Uygur nationality vs.13.3％ (8/60) for Han nationality,P ＜ 0.05),as well as among CMM lesions from different anatomical sites (13.6％ (6/42) in acral sites vs.11.8％ (4/29) in mucous membrane vs.45.8％ (11/32) in non-acral sites,P ＜ 0.05) and of different Clark levels (8.6％ (4/42) for grade Ⅰ-Ⅲ vs.12.4％ (17/61) for grade Ⅳ-Ⅴ,P＜ 0.05),but not between male and female CMM patients or between CMM patients with lymph node metastasis and those without (both P ＞ 0.05).IHC with the anti-BRAF V600E antibody showed a sensitivity of 100％ (15/15) and a specificity of 98.5％ (65/66) in detecting BRAF V600E mutation.Conclusions The expression of BRAF V600E mutant protein is up-regulated in CMM lesions,and CMM patients of Uygur nationality seems to have a higher expression rate than those of Han nationality.IHC appears to be an accurate and rapid method to detect V600E BRAF mutation.

OBJECTIVETo explore the integrative medicinal therapy for non-gonococcal cervicitis (NGC) in order to elevate the therapeutic effect for patients treated in vain after long-term application of antibiotics.

METHODSFifty patients with NGC were treated with Qingyuan decoction combined with antibiotics, and other 46 patients were treated with antibiotics alone for control.

Objective:To investigate the influence of sCD80-Linker-sCD40L fusion protein on the unspecific anti- tumor immunity in vitro.Methods:Ovarian cancer SKOV3 cells were separately transfected with recombinant adenoviral vectors containing sCD80-Linker-sCD40L fusion gene,sCD80 gene,sCD40L gene or with control adenovirus.The expres- sion of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of SKOV3 cells was determined by ELISA.Dendritic cells(DCs)were cultured with peripheral blood mononuclear cells from a patient with ovarian carcinoma.DCs and autologous T cells were co-cuhured and were exposed to different supernatants for 48 h. The allostimulatory effects of DCs on T cells were determined by mixed lymphocyte reaction(MLR).The unspecific kill- ing activities of induced T cells against SKOV3/K562 cells were measured by LDH-releasing assay.Results:ELISA assay showed that levels of the sCD80-Linker-sCD40L fusion protein,sCD80 protein and sCD40L protein in the supernatants of transfeced SKOV3 cells were 2.791 ng/ml,1.956 ng/ml and 1.407 ng/ml,respectively.The fusion protein-exposed DCs ([0.382?0.053]vs[0.167?0.028],P

Objective To assess the relationship between BRAF gene mutations and clinical phenotype of malignant melanoma.Methods Tissue specimens were collected from the lesions of 80 patients with malignant melanoma,and from the normal skin of 30 patients with trauma in the Department of Plastic Surgery or General Surgery,and subjected to paraffin embedding and DNA extraction.PCR was performed to amplify the exon 11 and 15 of BRAF gene followed by DNA sequencing.Chi-square test and Fisher's exact test were carried out to assess the relationship between BRAF gene mutations and clinical phenotypes of malignant melanoma.Results BRAF gene mutations were found in 19 (23.8％) of the 80 malignant melanoma specimens.Among the 19 mutationpositive specimens,17 (88.2％) carried mutations in exon 15 of BRAF gene with V600E as the most frequent (88.2％,15/17) mutation type,and 2 (10.5％) carried mutations in exon 11.No mutation was found in any of the normal skin tissue specimens.The average age at onset was 57.5 years in these patients.The frequency of BRAF gene mutation was significantly higher in patients younger than 60 years than in those older than 60 years (37.1％ vs.13.3％,x2=6.613,P ＜ 0.05).A significant difference was observed in the frequency of BRAF gene mutation among tissue specimens of mueosal,acral and non-aeral malignant melanoma (18.2％ (4/21) vs.14.7％(5/34) vs.41.7％ (10/24),x2=6.167,P ＜ 0.05).There was no significant association between BRAF gene mutation and gender,race or lymph node metastasis (all P ＞ 0.05).Conclusions BRAF gene is a hot spot for mutations in patients with malignant melanoma in Xinjiang Uygur Autonomous Region,with V600E point mutation in exon 15 as the most frequent mutation type.BRAF gene mutations appear to be closely correlated with the age at onset of and lesional sites in,but uncorrelated with gender and race of or lymph node metastasis in,patients with malignant melanoma.

OBJECTIVE: To explore the clinical feature and genetic etiology of a patient with Craniofacial nasal syndrome (CNFS). METHODS: A patient with CNFS who had presented at the Guiyang Maternal and Child Health Care Hospital on November 13, 2021 was selected as the study subject. Clinical data of the patient were collected. Peripheral venous blood samples were collected from the patient and her parents and subjected to trio-whole exome sequencing (trio-WES). Candidate variants were verified by Sanger sequencing and bioinformatic analysis. RESULTS: The patient, a 15-year-old female, had predominantly featured forehead bulging, hypertelorism, wide nasal dorsum and bifid nasal tip. Genetic testing revealed that she has harbored a heterozygous missense c.473T>C (p.M158T) variant of the EFNB1 gene, which was detected in either of her parents. By bioinformatic analysis, the variant has not been recorded in the HGMD and ClinVar databases, and no population frequency was recorded in the 1000 Genomes, ExAC, gnomAD and Shenzhou Genome Data Cloud databases. As predicted by the REVEL online software, the variant can confer deleterious effects on the gene or its product. Analysis using UGENE software showed the corresponding amino acid to be highly conserved among various species. Analysis with AlphaFold2 software suggested that the variant may affect the 3D structure and function of the Ephrin-B1 protein. Based on the American College of Medical Genetics and Genomics (ACMG) standards and guidelines and recommendation of Clinical Genome Resource (ClinGen), the variant was rated as pathogenic. CONCLUSION Combining the patient's clinical features and genetic finding, the diagnosis of CNFS was confirmed. The heterozygous c.473T>C (p.M158T) missense variant of the EFNB1 gene probably underlay the disease in this patient. Above finding has provided a basis for the genetic counseling and prenatal diagnosis for her family.

BACKGROUNDMounting evidence suggests that tumors are histologically heterogeneous and are maintained by a small population of tumor cells termed cancer stem cells. CD133 has been identified as a candidate marker of cancer stem cells in laryngeal carcinoma. This study aimed to analyze the chemoresistance of CD133(+) cancer stem cells.

METHODSThe response of Hep-2 cells to different chemotherapeutic agents was investigated and the expression of CD133 was studied. Fluorescence-activated cell sorting analysis was used to identify CD133, and the CD133(+) subset of cells was separated and analyzed in colony formation assays, cell invasion assays, chemotherapy resistance studies, and analyzed for the expression of the drug resistance gene ABCG2.

RESULTSAbout 1% - 2% of Hep-2 cells were CD133(+) cells, and the CD133(+) proportion was enriched by chemotherapy. CD133(+) cancer stem cells exhibited higher potential for clonogenicity and invasion, and were more resistant to chemotherapy. This resistance was correlated with higher expression of ABCG2.

CONCLUSIONSThis study suggested that CD133(+) cancer stem cells are more resistant to chemotherapy. The expression of ABCG2 could be partially responsible for this. Targeting this small population of CD133(+) cancer stem cells could be a strategy to develop more effective treatments for laryngeal carcinoma.
