Objective To assess the abstracts on randomized controlled trials ( RCT) in non-small cell lung cancer ( NSCLC) published in Chinese and their influencing factors.Methods RCT in NSCLC published in Chinese were included according to the CONSORT statement and their influencing factors were analyzed by RevMan 5.3 soft-ware.Results The titles were identified as random, randomization, blinding, statistical method, recruited partici-pants, trial registry and fund-supported, respectively, in 20%of the 2677 abstracts included in this study.Con-clusion The titles are identified as random, randomization, blinding, statistical method, recruited participants, trial registry and fund-supported in RCT published in Chinese.Although the abstracts are improved after the publication of CONSORT, they need to be further brushed up.

Aim To investigate anti-hepatic fibrotic mechanism of Acanthus ilicifolius alkaloid A ( HBOA ) involved in high mobility group box 1 ( HMGB1 ) . Methods A hepatic fibrosis model of rat was estab-lished by the olive oil of CCl4 for 12 weeks. Then, at the 8th week,the successful model rats were randomly divided into model control group, colchicine group, HBOA high-dose group and HBOA low-dose group. From the 9th week,the rats in each group were treated with the drugs daily for 4 weeks respectively. The changes of liver histopathology and collagen were ob-served by HE staining and Masson staining, and the serum indicators including aspartate aminotransferase (AST),alanine aminotransferase(ALT) , total biliru-bin ( T-BIL ) , HMGB1 , interleukin-1β( IL-1β) and tumor necrosis factor-α( TNF-α) were determined. Moreover , the protein of HMGB1 in liver was examined by immunohistochemistry, and the expression of HMGB1 mRNA was measured by real-time fluores-cence quantitative PCR. Results Compared with the model control group,HBOA high-dose and HBOA low-dose groups significantly attenuated the fibrotic degree induced by CCl4 , markedly decreased the levels of ALT, AST, T-BIL, HMGB1, IL-1β, TNF-α. Moreo-ver, the expression of HMGB1 protein and mRNA in liver was decreased. And furthermore, serum HMGB1 level had significant positive correlation with IL-1β, TNF-α,ALT,AST and T-BIL. Conclusion HBOA has beneficial effects against liver fibrosis in rat which is induced by CCl4 , the mechanisms may be related to the inhibition of inflammatory response to HMGB1 .

Collection and quality control of inpatient medical record home page information are key to the study and use of DRGs.The paper covered the sampling methods, inspection items, inspection methods, data assembly methods, and data reporting quality scoring methods of Beijing authorities on the hospitals in the city.Also introduced were the inspection results of the city in 2014, which prove a satisfactory outcome in the end.

ObjectiveTo find out the incidence of triple-negative breast cancer(TNBC) in all kinds of breast cancers.To compare and analyze the clinicopathological features,recurrence,metastasis,and prognosis of patients with TNBC and non-triple negative breast cancer (non-TNBC).MethodsThe clinicopathological features and follow-up data of 387 patients with primary breast cancer histopathologically conffirmed in our hospital from Sep.2004 to Sep.2006 were retrospectively analyzed.The 387 patients were divided into 2 groups:79 cases of TNBC and 308 cases of non-TNBC.The clinical features and prognosis of the 2 groups were compared.Results Compared with non-TNBC group,patients in TNBC group had their special features:1.higher ratio of patients ＜ 35 years( P =0.012 ) ; 2.higher ratio of patients with family history of breast cancer( P =0.031 ) ; 3.higher ratio of tumors with maximum diameter ≥ 5 cm ( P =0.044 ) ; 4. higher ratio of patients with positive lymph nodes(P =0.011 ) ; 5.higher ratio of tumors in clinical stage Ⅲ(P =0.007) ; 6.higher ratio of tumors in histological stage Ⅲ(P =0.028 ).The 5-year-disease-free survival (DFS) and overall survival (OS) rate for patients with TNBC were 72.15％ and 88.61％ respectively,lower than those of non-TNBC ( P =0.003 and 0.031 respectively).ConclusionsCompared with non-TNBC patients,patients with TNBC have the features of younger age,more advanced clinical stage upon diagnose,higher rate of lymph node metastasis,larger tumors,higher histological grade,faster and easier recurrence and metastasis,and lower rate of DFS and OS.The information of age,the maximum diameter of the tumor,lymph node status,clinical stage,histological grade and pathological types,especially the age and lymph node status,play an important role in predicting the prognosis of TNBC.

Objective To analyze the clinical and pathological characteristics of Alport syndrome in children. Methods Clinical and pathological information gathered from 62 patients during March 1989 to August 2012 was retrospectively analyzed. Results Four autosomal recessive Alport syndromes (AR-AS) and 58 X-linked Alport syndromes (XL-AS) were analyzed. Of the XL-AS, 47 were boys and 11 were girls. Most of patients induced by upper respiratory tract infections, and onset with hematuria and proteinuria. There was no signiifcant gender difference in family history, impaired renal tubular proteins, hypertension, im-paired renal function, hearing loss, ocular abnormalities or renal pathological changes under light microscopy. However, extensive lamination and split of glomerular basement membrane (GBM) dense layers were found in 83.0%male and 18.2%female patients (P=0.000) and the rest patients were presented with limited distribution of typical GBM changes. Proteinuria progressed signiif-cantly with age in XL-AS males (r=0.501, P=0.000). Five XL-AS patients developed to end stage renal disease (ESRD) between 11 to 16 years old. Conclusions XL-AS is the main inherited type and severe changes of GBM are common in XL-AS males. Proteinuria increases remarkably with age. The detection of type IV collagen in renal tissue or skin is helpful to diagnose Alport syndrome and conifrm inheritance modes.

Objective:To investigate the efficacy and safety of SIMPLE regimen in the treatment of extranodal NK/T-cell lymphoma (ENKTCL).Methods:The clinical data of 11 patients with ENKTCL who were admitted to the University of Hong Kong-Shenzhen Hospital from January 2012 to January 2022 were retrospectively analyzed. The patients received 4-6 courses of SIMPLE (cisplatin, gemcitabine, ifosfamide, etoposide, dexamethasone, and pegasparaginase) regimen chemotherapy, and stage Ⅰ and Ⅱ patients who also received local radiotherapy after 2 or 3 courses of chemotherapy. Patients were evaluated for mid-treatment and end-of-treatment outcomes, and the adverse effects of patients were evaluated in each treatment cycle. The Kaplan-Meier method was used to analyze the progression-free survival (PFS) and overall survival (OS) of the 11 patients.Results:All 11 patients were nasal type, with the median age of 41 years old (26-67 years old), including 5 males and 6 females, 3 relapsed cases and 8 newly treated cases. Of the 10 patients evaluated for efficacy, 9 achieved complete remission and 1 achieved at least partial remission (efficacy was assessed based on follow-up). All 11 patients were followed up for a median time of 50 months (15-72 months) and 2 relapsed patients died due to disease progression. The expected 5-year PFS rate and OS rate of 11 patients were both 90.0%, and the expected 5-year OS rate was 100.0% and 66.6% in newly treated and relapsed patients, respectively. Common adverse effects were hematologic adverse reactions, infections, gastrointestinal symptoms, elevated transaminases, and hypofibrinogenemia, all of which were curable. There is no treatment-related death.Conclusions:The SIMPLE regimen for the treatment of ENKTCL has a high remission rate, the patients have long survival time, and the regimen is moderately well tolerated.
