BACKGROUNDThis study aimed to evaluate the effects of standard rescue procedure (SRP) in improving severe trauma treatments in China.

METHODSThis study was conducted in 12 hospitals located in geographically and industrially different cities in China. A standard procedure on severe trauma rescue was established as a general rule for staff training and patient treatment. A regional network (system) efficiently integrating prehospital rescue, emergency room treatments, and hospital specialist treatments was built under the rule for information sharing and improving severe trauma treatments. Treatment outcomes were compared between before and 1 year after the implementation of the SRP.

RESULTSThe outcomes of a total of 74,615 and 12,051 trauma cases were collected from 12 hospitals before and after the implementation of the SRP. Implementation of the SRP led to efficient cooperation and information sharing of different treatment services. The emergency response time, prehospital transit time, emergency rescue time, consultation call time, and mortality rate of patients were 24.24 ± 4.32 min, 45.69 ± 3.89 min, 6.38 ± 1.05 min, 17.53 ± 0.72 min, and 33.82% ± 3.87% (n = 441), respectively, before the implementation of the standardization and significantly reduced to 10.11 ± 3.21 min, 22.39 ± 4.32 min, 3.26 ± 0.89 min, 3.45 ± 0.45 min, and 20.49% ± 3.11%, separately (n = 495, P < 0.05) after that.

CONCLUSIONSStaff training and SRP can significantly improve the efficiency of severe trauma treatments in China.

Adult-onset Still's disease (AOSD) is a rare but clinically well-known, polygenic, and systemic autoinflammatory disease, which is characterized by spiking fever, evanescent skin rash, arthralgia, and sore throat. The application of non-steroidal anti-inflammatory drugs and glucocorticoids, which are first-line therapies of AOSD, is limited due to their side effects such as liver injury or disorder of blood glucose. Therefore, patients who suffer from systemic diseases in China prefer to seek help from Chinese herbal medicine (CHM), which is an important part of complementary and alternative medicine. In this case, we report a 28-year-old male badminton coach presenting with a 15-day history of fever and skin rash, accompanied by sore throat, fatigue, myalgia and chills. Additionally, hepatosplenomegaly, multiple lymphadenopathies, aminotransferase abnormality, and elevated inflammatory factor levels were observed during hospitalization. Infectious diseases, solid tumors, hematological diseases, and common autoimmune diseases were excluded. Not benefitting from antibiotic therapy, the patient was finally diagnosed with AOSD, after a careful examination, then showed rapid remission after a six-week treatment with CHM granules based on Xiaochaihu Decoction and Yinqiao Powder. After stopping the treatment, there was no relapse within a 15-month follow-up period. To the best of our knowledge, this is the first well-documented case of this successful treatment. The present case report suggests that CHM is a reliable choice for complementary and alternative therapy for AOSD, but confirming the utility of CHM for AOSD requires further support from prospective studies.

OBJECTIVETo investigate the cytogenetic abnormalitis in patients with diffuse large B-cell lymphoma(DLBCL) patients with bone marrow involvement and their influence on prognosis.

METHODSConventional karyotyping was performed on bone marrow specimens in 47 DLBCL patients with histologically confirmed bone marrow involvement(BMI). The karyotyping results of bone marrow, the characteristics and clinical effect of chromosomal abnormalities were analysed.

RESULTSIn 47 DLBCL cases with BMI, the chromosomal abnormalities were detected in 25(53%) cases. Among them, complex karyotype was more frequent, being noted in 19(40%) patients. The most frequently involved chromosomes were chromosome 1 and 18(both 26%), others were chromosome 3(23%), 6(19%), 7, 8 and 14(13%). Among all karyotype changes, the most common numerical aberrations, in decreasing order of incidence, were trisomy 3(13%), trisomy 5, trisomy 7, trisomy 12, trisomy 18 and loss of 21(6%,each), and the most predominant structural aberrations, in decreasing order of incidence, were 1q+(17%), 1p+, 6q-, 8q+, 14q+, 18p+, 18q+ and aberrations involving band 2p21-p23 (6%,each). The prognostic impact analysis of both clinical features and cytogenetic aberrations revealed that IPI≥3 (P=0.03) or the presence of chromosomal abnormalities (P=0.005) were significantly related with poor progression free survival(PFS), and IPI≥3 (P=0.024), lactate dehydrogenase(LDH)≥ three times of the upper limit of normal (P=0.027) and the presence of chromosomal abnormalities (P=0.001) predominantly related with poor overall survival(OS). In multivariate analysis, the presence of chromosomal abnormalities was the only independently adverse factor for PFS(P=0.037, HR 2.323) and OS(P=0.015, HR 2.833). The analysis of prognostic effects of specific chromosomal aberrations showed that patients with specific cytogenetic abnormalities of 1q+, 8q+, +12, 12q+, 18p+ and aberrations involving band 2p21-23 had significantly poor PFS, and patients with specific cytogenetic abnormalities of 1q+, +3, +5, +7, 8q+, +12, 12q+ and aberrations involving band 2p21-23 had significantly poor OS. When the above mentioned specific chromosomal aberrations were analyzed with clinical covariate, the presence of chromosomal aberration of 8q+ (P=0.022, HR 2.701) and IPI≥3 (P=0.043, HR 2.949) were independently poor prognostic factors for PFS, and 1q+ (P=0.032, HR 2.973) was the independently poor prognostic factor for OS.

CONCLUSIONIn DLBCL patients with BMI, the presence of chromosomal abnormalities is the only independently poor factor for PFS and OS, and among them, the specific cytogenetic aberrations of 8q+ or 1q+ have an independently poor prognostic impact on PFS or OS, respectively, which need to be further studied.
