Abstract: Objective　To explore the epidemiological and clinical characteristics of non-tuberculous mycobacterial(NTM) pulmonary disease in Hainan in recent years, and to provide data support for the prevention and treatment of NTM pulmonary disease. Methods　Medical records of patients diagnosed with NTM pulmonary disease who treated at the Second Affiliated Hospital of Hainan Medical University (Hainan Provincial Tuberculosis Hospital) from January 2018 to December 2022 were collected. The demographics, regional distribution, temporal distribution, distribution of mycobacterial species, clinical symptoms, and radiological imaging changes of these patients were analyzed. Results　A total of 225 confirmed cases of NMT pulmonary disease were collected in this study, with 133(59.1%) female patients outnumbering 92(40.9%) male patients. The disease predominantly affected people over 50 years old, with 192 cases (85.3%), and the major onset age range was 61-<81 years old, with a median age of 63 and an average age of 62. Farmers comprised the majority of the patients, with 112 cases (49.8%). More patients were from the western region (90 cases, 40.0%) than from the central region (76 cases, 33.8%), followed by the eastern region (59 cases, 26.2%). A total of 10 strains were detected from 225 samples, with the most common strains being Mycobacterium intracellulare (92 cases, 40.9%), Mycobacterium chelonae/abscessus(80 cases, 35.6%), and Mycobacterium avium (15 cases, 6.7%), followed by Mycobacterium kansasii (5 cases, 2.2%), Mycobacterium fortuitum (4 cases, 1.8%), and Mycobacterium parascrofulaceum (3 cases, 1.3%). There were 10 cases (4.5%) of mixed infections, including Mycobacterium avium and Mycobacterium intracellulare (8 cases, 3.6%), Mycobacterium intracellulare and Mycobacterium chelonae/abscessus (1 case, 0.4%), and Mycobacterium fortuitum and Mycobacterium chelonae/abscessus (1 case, 0.4%). The primary clinical manifestations of NTM pulmonary disease included cough and sputum (219 cases, 97.3%), hemoptysis (92 cases, 40.9%), fever (61 cases, 27.1%), dyspnea (57 cases, 25.3%), night sweats (52 cases, 23.1%), weight loss (50 cases, 22.2%), and thoracodynia (35 cases, 15.6%). There was no significant difference in symptoms between male and female patients. Pleural thickening (188 cases, 83.6%) and bronchiectasis (151 cases, 67.1%) were the most common imaging changes in NTM pulmonary disease, followed by cavities (93 cases, 41.3%), emphysema (41 cases, 18.2%), and lung damage (28 cases, 12.4%). Male patients were more likely to have lung damage and emphysema, while female patients were more likely to have bronchiectasis. Conclusions　The distribution of NTM species is diverse in Hainan area, with Mycobacterium intracellulare, Mycobacterium chelonae/abscessus, and Mycobacterium avium are dominant species. NTM pulmonary disease and pulmonary tuberculosis have similar clinical features, which requires attention for differentiation in clinical practice.

Objective To analyze the protein expression profile of HeLa cells transfected with pORF5 gene of Chlamydia trachomatis. Methods A lentiviral expression vector containing pORF5 gene was constructed. The lentiviral expression vector and helper plasmids were co-transfected into 293T cells to construct the recombinant lentivirus, which was used to infect HeLa cells. HeLa cells transfected with pORF5 gene and control HeLa cells were sorted out by flow cytometry. The isobaric tags for relative and absolute quantitation ( iTRAQ) approach combined with nano-liquid chromatography-tandem mass spec-trometry ( NanoLC-MS/MS) analysis was performed to understand protein expression profiles and to iden-tify and quantify the differentially expressed proteins in the pORF5-transfected HeLa cells ( pORF5-Hela) and the control HeLa cells. Quantitative real-time PCR ( qRT-PCR ) and Western blot analysis were performed to detect the expression of some proteins at mRNA and protein levels, respectively. Results HeLa cell line stably transfected with pORF5 gene and control HeLa cell line were constructed successful-ly. Totally 314 proteins were differentially expressed between the pORF5-HeLa and control HeLa cells, 159 of which showed increased expression and the other 155 showed decreased expression in pORF5-HeLa cells. The differentially expressed proteins were involved in many processes, such as metabolic process, immune response, biological adhesion and so on. Results of qRT-PCR showed that the expression of HIST1H1C(histone H1. 2C), HBA1(hemoglobin subunit alpha), PARK7(parkinson disease protein 7), HMGB1(high mobility group protein B1) and HMGB2 at mRNA level in pORF5-HeLa cells were up-regulated, while the expression of CLIC1 ( chloride intracellular channel protein 1 ) , KRT7 ( typeⅡ cy-toskeletal 7), SFN(14-3-3 protein sigma) and CDKN2A(cyclin-dependent kinase inhibitor 2A) were down-regulated. Western blot analysis confirmed the enhanced expression of HMGB1 and PRAK7 at pro-tein level. The results of qRT-PCR and Western blot analysis were consistent with proteomic data. Con-clusion Expression profiles for differentially expressed proteins between pORF5-HeLa and control HeLa cells were established successfully. The differentially expressed proteins regulated by pORF5 gene were found to be related to cell metabolism, proliferation, adhesion and so on, suggesting that pORF5 might promote the growth and proliferation of Ct by regulating protein expression and biological behavior of host cells.

Objective To evaluate the outcomes of children with stage Ⅳ malignant extracranial germ cell tumors. Methods Twenty-five patients were enrolled in the retrospective analysis. Event-free survival (EFS) and overall survival (OS) rates were estimated by Kaplan-Meier method with SPSS 13.0. Results Of the 25 children, there were 13 males and 12 females. The mean age at diagnosis was 2 years old (ranged 1 to 11). Five patients receiving chemotherapy in another hospital before (n=1), or giving up treatment after confirmed diagnosis (n=1), or giving up effective treatment after received less than 2 cycles (n=3) were excluded from this analysis. Of the 20 patients, 90.0% (18/20) achieved complete remission and 5.0% (1/20) achieved partial remission after treatment. The 5-year EFS rate and 5-year OS rate were 70.0%±10.2% and 82.4%±9.2% respectively. There was no death occurred due to complications. Conclusions The effect of this treatment program is positive. The cumulative dose of the drugs is not high, compared with other schemes such as PEB, but there are more drugs involved. Whether these drugs may cause long-term adverse reactions needs further research.

Objectives To analyze the clinical features and long-term follow-up results of neuroblastoma (NB) without chemotherapy and radiotherapy, and to provide evidence for further improvement of treatment. Methods The clinical data of children diagnosed with NB who received operation during January 2005 to December 2015 was retrospectively analyzed, and the long-term follow-up results were evaluated. Results In 57 cases of NB, 43 cases (81.1％) were in stage 1, 8 cases were in stage 2 and 2 cases were in stage 4S. The median age at diagnose was 7 months (11 days - 10 years and 11 months). There were 47/51 cases had the pathological type with a good prognosis (accounting for 92.2％). FISH was detected in 1/49 case which had the amplification at greater than 10 copies. 56/57 cases underwent surgical resection of the primary tumor, 50 cases of which were completely resected, and 3 cases had very good partial remission after tumor resection. The abdominal mass was found in the uterus in 1 case, and surgical operation was not performed and the imaging was regularly checked for follow-up , and the mass subsided completely at 7-month-old. The median follow-up time was 36 months (4 - 99 months). Five children were lost to follow-up and the median time of follow-up was 19 months (4 - 45 months). One child in stage 4S relapsed at 1 year of follow-up, 2 cases in stage 1 relapsed at 6 months of follow-up. Five years event free survival rates (EFS) in all patients were 94.6％, and overall survival rate (OS) of the 5 years was 100％. Conclusions Children younger than 18 months without MYCN amplification in the stages 1 and 2 are safe by surgical treatment alone with good prognosis. Simple surgical treatment can also be extended to all age groups of NB without MYCN amplification in the stages 1 or 2.
