To explore the clinical characteristics, diagnosis, treatment outcome and prognosis of de novo CD5 positive diffuse large B cell lymphoma (CD5(+)DLBCL), clinical data of 10 patients with pathologically confirmed CD5(+)DLBCL were retrospectively analyzed. The results indicated that 9 out of 10 patients were older than 60 years. All cases were in III/IV stages according to Ann-Arbor Staging System. Bone marrow biopsy with immunohistochemistry showed lymphoma involvement in 5 cases. Nine patients received chemotherapy with anti-CD20 monoclonal antibody (Rituximab) except one. Five cases achieved CR, two cases achieved PR, two cases achieved SD, one case achieved PD. Eight cases died within 2 years because of relapse or disease progression, in which 3 cases developed central nervous system lymphoma. The median survival time was 16 (1-23) months, 2-year survival rate was 20.40%. It is concluded that de novo CD5(+) DLBCL is rare in clinic, but it is a kind of highly aggressive lymphoma with poor prognosis. So, new treatment strategy should be explored.

The aim of this study was to analyze the clinical features and laboratory findings of adult Epstein-Barr virus associated T/NK cell lymphoproliferative disease (EBV+T/NK-LPD) and to investigate the early diagnosis and prognosis of EBV+T/NK-LPD. The clinical data of 19 adult patients with EBV+T/NK-LPD were retrospectively analyzed. The results indicated that there were 11 males and 8 females. The median age was 32 years (range: 20-70 years). The average duration from onset of symptoms to diagnosis was 3.5 months. The median survival time was 2.5 months. Unkown fever, hepatosplenomegaly, liver dysfunction and interstitial pneumonia were the main clinical features. High levels of β2-MG, LDH, TNF, IL-6 and significantly increased EBV-DNA level (median level > 10(6) copies/ml) were occurred in all the patients. Cytopenia was seen in 18 cases. Morphologically, atypical large granular lymphocytes and hemophagocytosis were common in bone marrow smears. Deletion of CD5 or CD7 were frequently observed in T/NK lymphocytes in bone marrow cells by flow cytometry. Bone marrow biopsy showed atypical lymphocyte interstitial infiltrated in 10 cases, while a few large cells infiltrated in 6 cases. Immunohistochemistry showed the expression of CD3(+)CD56(+) were seen in 2 cases, CD3(+)CD8(+) in 11 cases and CD3(+)CD4(+) in 3 cases. TIA-1 and EBER were positive in all biopsy specimens. Three cases underwent biopsy of lymph nodes showed reactive proliferations of lymphocytes. All the patients died of multiorgan failure. It is concluded that the fever, hepatosplenomegaly are the most common clinical features in adult EBV+T/NK-LPD, the bone marrow infiltration of EBV-infected T/NK lymphocytes and significantly increased EBV-DNA level can be observed in all cases, the clinical outcome of this disease is poor, these clinical and experimental features can be served as a reliable marker for the timely diagnosis of adult EBV+T/NK-LPD.

Clinical expertise, patient preference, and the best evidence are the three elements of evidence-based medicine. Based on high-level and high-quality evidence, qualitative and quantitative analysis of the prescribing decisions of physicians is beneficial to improving clinical efficacy. A mature methodological system is available for the retrieval, analysis, summary, evaluation, and recommendation of the evidence, but there are still few studies on physicians' prescribing decisions. How to analyze the trend of physicians' prescribing decisions based on the priority ranking in addition and subtraction of prescriptions? Analytic hierarchy process(AHP) is a method for decision making, which arranges the elements of the decision problem into overall goal, criteria, and operational sub-criteria, and uses the matrix eigenvector method to solve the problem. This study aims to analyze the priority of physicians' prescribing decisions for diabetes mellitus with deficiency of both Qi and Yin based on AHP. To be specific, a database of diabetes mellitus cases with deficiency of both Qi and Yin was established and AHP was used to yield the priority ranking of Chinese patent medicine prescriptions in specific clinical scenarios. In the selected cases of diabetes mellitus with deficiency of both Qi and Yin, Xiaoke Pills was the best prescription for the treatment of type 2 diabetes mellitus(deficiency of both Qi and Yin)(normalized=0.388), followed by Liuwei Dihuang Pills(normalized=0.269), Qishen Capsules(normalized=0.230), and Shengmai Injection(normalized=0.113). According to the analysis the available data, for type 2 diabetes mellitus(deficiency of both Qi and Yin), Xiaoke Pills was the most effective prescription in specific scenarios. When the physicians' prescribing decisions are consistent with the evidence, quantitative analysis of physicians' cognition will boost the evidence-based medical decision-making. However, the research results are also affected by the quality of literature, evidence level and priority, which are thus have some limitations. It is recommended that further small data research based on individual cases be carried out to lay a evidence-based basis for the clinical decision-making of type 2 diabetes mellitus.

Shenfu Injection(SFI) is praised for the high efficacy in the treatment of septic shock. However, the precise role of SFI in the treatment of sepsis-associated lung injury is not fully understood. This study investigated the protective effect of SFI on sepsis-associated lung injury by a clinical trial and an animal experiment focusing on the hypoxia-inducing factor-1α(HIF-1α)-mediated mitochondrial autophagy. For the clinical trial, 70 patients with sepsis-associated lung injury treated in the emergency intensive care unit of the First Affiliated Hospital of Zhengzhou University were included. The levels of interleukin(IL)-6 and tumor necrosis factor(TNF)-α were measured on days 1 and 5 for every patient. Real-time quantitative polymerase chain reaction(RT-qPCR) was performed to determine the mRNA level of hypoxia inducible factor-1α(HIF-1α) in the peripheral blood mononuclear cells(PBMCs). For the animal experiment, 32 SPF-grade male C57BL/6J mice(5-6 weeks old) were randomized into 4 groups: sham group(n=6), SFI+sham group(n=10), SFI+cecal ligation and puncture(CLP) group(n=10), and CLP group(n=6). The body weight, body temperature, wet/dry weight(W/D) ratio of the lung tissue, and the pathological injury score of the lung tissue were recorded for each mouse. RT-qPCR and Western blot were conducted to determine the expression of HIF-1α, mitochondrial DNA(mt-DNA), and autophagy-related proteins in the lung tissue. The results of the clinical trial revealed that the SFI group had lowered levels of inflammatory markers in the blood and alveolar lavage fluid and elevated level of HIF-1α in the PBMCs. The mice in the SFI group showed recovered body temperature and body weight. lowered TNF-α level in the serum, and decreased W/D ratio of the lung tissue. SFI reduced the inflammatory exudation and improved the alveolar integrity in the lung tissue. Moreover, SFI down-regulated the mtDNA expression and up-regulated the protein levels of mitochondrial transcription factor A(mt-TFA), cytochrome c oxidase Ⅳ(COXⅣ), HIF-1α, and autophagy-related proteins in the lung tissue of the model mice. The findings confirmed that SFI could promote mitophagy to improve mitochondrial function by regulating the expression of HIF-1α.

Background: In China, secondary cytoreductive surgery (SCR) has been widely used in ovarian cancer (OC) over the past two decades. Although Gynecologic Oncology Group-0213 trial did not show its overall survival benefit in first relapsed patients, the questions on patient selection and effect of subsequent targeting therapy are still open. The preliminary data from our pre-SOC1 phase II study showed that selected patients with second relapse who never received SCR at recurrence may still benefit from surgery. Moreover, poly(ADP-ribose) polymerase inhibitors (PARPi) maintenance now has been a standard care for platinum sensitive relapsed OC. To our knowledge, no published or ongoing trial is trying to answer the question if patient can benefit from a potentially complete resection combined with PARPi maintenance in OC patients with secondary recurrence. Methods SOC-3 is a multi-center, open, randomized, controlled, phase II trial of SCR followed by chemotherapy and niraparib maintenance vs chemotherapy and niraparib maintenance in patients with platinum-sensitive second relapsed OC who never received SCR at recurrence. To guarantee surgical quality, if the sites had no experience of participating in any OC-related surgical trials, the number of recurrent lesions evaluated by central-reviewed positron emission tomography–computed tomography image shouldn't be more than 3. Eligible patients are randomly assigned in a 1:1 ratio to receive either SCR followed by 6 cyclesof platinum-based chemotherapy and niraparib maintenance or 6 cycles of platinum-based chemotherapy and niraparib maintenance alone. Patients who undergo at least 4 cycles of chemotherapy and must be, in the opinion of the investigator, without disease progression, will be assigned niraparib maintenance. Major inclusion criteria are secondary relapsed OC with a platinum-free interval of no less than 6 months and a possibly complete resection. Major exclusion criteria are borderline tumors and non-epithelial ovarian malignancies, received debulking surgery at recurrence and impossible to complete resection. The sample size is 96 patients. Primary endpoint is 12-month non-progression rate.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

OBJECTIVETo investigate the clinical and laboratory features of patient with B cell lymphoma associated hemophagocytic syndrome(B-LAHS).

METHODSThe clinical data of 10 cases of B-LAHS were retrospectively analysed and the relevant literatures were reviewed.

RESULTSThe median age of 10 cases diagnosed as B-LAHS was 55.5 (31-88) years old, and median time from attack to diagnosis was 2 months (2 weeks-4 months). The diagnosis can be made histopathologically and immunohistochemically by bone marrow biopsy. Among them 7 cases were diagnosed as large B cell lymphoma, 2 cases as mantle cell lymphoma and 1 case as small B cell lymphoma. The prominent clinical symptoms and signs were persistent fever (100%) and splenomegaly(90%), and the involvements with respiratory and digestive system were common. Another 1 case had systemic muscle pain and lactic acidosis as the first onset. Laboratory studies showed hepatic dysfunction, significantly elevated ferritin and lactate dehydrogenase, abnormal lymphocytes in peripheral blood smear, and hemophagocytosis in bone marrow smear. The FSC/SSC abnormalities of cloned B lymphoma cells were detected through flow cytometry (FCM). The complete remission (CR) was maintained in 4 cases receiving immunochemotherapy based on rituximab.

CONCLUSIONB-LAHS possesses heterogeneous clinical manifestations and rapid deterioration. Bone marrow biopsy and immunohistochemical examination can confirm the diagnosis. FCM may improve the early diagnosis of B-LAHS.

OBJECTIVE: To evaluate the effectiveness and safety of mechanical thrombectomy treatment in patients with acute ischemic stroke (AIS),and to explore influential factors of the clinical prognosis preliminarily. METHODS: Clinical data of 26 patients with acute cerebral arterial occlusion treated with mechanical thrombectomy in Peking University Third Hospital from January 2014 to June 2017 were retrospectively collected. The immediate effects of the 26 patients in this group after mechanical thrombectomy treatment were analyzed,The national institutes of health stroke scale (NIHSS) scores between preoperative and at discharge of the 26 patients in this group were compared,and modified Rankin scale (mRS) scores of 90 days post operation were analyzed to assess the prognosis of the 26 patients in this group. RESULTS: (1)In this group, 23 patients (88.5%) achieved vascular recanalization evaluated by thrombolysis in cerebral ischemia scale scores [thrombolysis in cerebral ischemia scale (TICI) scores, 3/2b grades were recognized as vascular recanalization], 19 patients of them reached TICI grade 3 and 4 atients reached TICI grade 2b. In this group 3 patients (11.5%) encountered symptomatic intracranial hemorrhage, 2 patients of them recovered after cerebral hemorrhage absorbed and 1 patient died of massive cerebral hemorrhage. In this group 4 patients (15.4%) died after mechanical thrombectomy treatment,2 patients died of hernia of the brain caused by severe cerebral edema, 1 patient died of symptomatic intracranial hemorrhage and 1 patient died of extensive subarachnoid hemorrhage. (2)The assessment of NIHSS scores at discharge(5.3±2.1)showed significantly lower than those preoperatively(12.6±4.2), P<0.01,and in this group 12 patients (46.2%) achieved favourable prognosis (defined as mRS scores 0-2), 6 patients of them reached mRS 0 score,4 patients reached mRS 1 score and 2 patients reached mRS 2 scores. CONCLUSION Mechanical thrombectomy with stent retriever contributed to a high rate of vascular recanalization and favourable prognosis,but some patients had poor prognosis, suggesting that we should screen the enrolled patients strictly.

OBJECTIVETo explore the lymphocytic clonal expansion in adult patients with Epstein-Barr virus-associated lymphoproliferative diseases (EBV+LPD), and to investigate the experimental methods for EBV+LPD cells so as to provide a more objective measure for the diagnosis, classification and prognosis in the early stage of this disease.

METHODSPeripheral blood samples from 5 patients with EBV+LPD, 4 patients with adult infectious mononucleosis(IM) as negative control and 3 patients with acute NK-cell leukemia(ANKL) as positive control were collected. Prior to immunochemotherapy, viral loads and clonality were analysed by flow cytometry (FCM), T cell receptor gene rearrangement (TCR) was detected by real-time polymerase chain reaction (RT-PCR), and diversity of EB virus terminal repeat (EBV-TR) was detected by Southern blot.

RESULTSFCM showed only 1 case with clonal TCRVβ in 5 patients with EBV+LPD, TCR clonal expansion could be detected both in patients with IM(4 of 4) and 4 patients with EBV+LPD(4 of 5), Out of patients with EBV+LPD, 1 patient displayed a monoclonal band and 2 patients showed oligoclonal bands when detecting EBV-TR by southen blot.

CONCLUSIONDetecting the diversity of EBV-TR by Southern blot may be the most objective way to reflex clonal transformation of EBV+LPD, which is of great benefit to the diagnosis, classification and prognosis in the early stage of this disease.
