Objective To evaluate the clinical efficiency of glucocorticoids in treatment of severe hepatitis.Methods A systematic review on the efficacy of glucocorticoids in treatment of severe hepatitis was conducted.Relevant literatures were searched in PubMed (1966-2011),EMCC (1995-2011),Springer,CNKI,Wanfang Database and CBM.The retrieved literatures were screened according to the predefined inclusion and exclusion criteria.RevMan 5.0 statistical software was used for Meta-analysis.The mortality was evaluated by relative risk (RR),while the total bilirubin (TBil),ALT and prothrombin activity (PTA) were evaluated by weighted mean difference (WMD) and 95％ confidential interval (CI).The publication bias and sensitivity about the data were measured by forest plot and funnel plot.Results Twenty-three papers involving a total of 1457 patients were included in the study.Compared to control group,the mortality in glucocorticoids-treated group was lower (RR =0.39,95％ CI:0.32-0.47,Z =9.75,P＜0.01); and the TBil (WMD=-88.03,95％CI:-112.80-63.26,Z=6.97,P＜0.01),ALT (WMD=-25.04,95％CI:-42.23-7.84,Z=2.85,P＜0.01) and PTA levels (WMD=21.56,95％ CI:6.52-36.60,Z=2.81,P ＜0.01) in glucocorticoids-treated group were improved.Conclusion Glucocorticoids can effectively improve TBil,ALT and PTA levels,and reduce the mortality of patients with severe hepatitis.

Objective The study was aimed to investigate the effects of transforming growth factor beta1(TGF-?1)on acute graft-versus-host disease(aGVHD)after allogeneic bone marrow transplantation(allo-BMT).Methods The recipient was male BABL/C.The donor was male C57BL/6.The murine model of aGVHD had been established by allo-BMT with donor derived T cells.There were four groups in this study:control group,radiation group,transplantation control group and TGF-?1 group.The mice in TGF-?1 group were administered TGF-?1[1 ?g/(kg?d)]subcutaneously two days before transplantation until seven days after it.Results The study showed that the survival time of TGF-?1 group was significantly longer than the transplantation control group,and the aGVHD pathological changes were milder in TGF-?1 group than in transplantation control group.Seven days after transplantation,the level of IL-2 of TGF-?1 group was higher than control group,but significantly lower than transplantation control group.The level of IL-10 of TGF-?1 group was significantly higher than transplantation control group.Conclusion TGF-?1 can prevent the lethal aGVHD and raise the survival rate after allo-BMT in murine model.It may prevent the lethal aGVHD by accommodating the Th1 and Th2 cytokine level in vivo.

Objective:To study the experience of frontline medical workers in COVID-19 quarantine points.Methods:Purposive sampling method was employed and 12 frontline medical workers in COVID-19 points of Zhaoyuan City were selected for semi-structured and in-depth interview. Colaizzi′s seven-step analysis method was adopted to analyze and categorize the data.Results:The real experience of frontline medical workers in quarantine points were classified into five themes: professional mission and pride, inadequate initial response in dealing with public health emergencies (shortage of personal protective equipment,inadequate preparation of medical workers and imperfect settings of quarantine points), having some negative emotions (worrying about being infected and feeling fearful for family members), facing complex and diverse working difficulties (repugnance and diversified demands of people quarantined, heavy workload, discomfort from personal protective equipment and occupational exposure), and gaining support and appreciation (getting support from epidemic control and prevention departments as well as medical systems and winning appreciation from people quarantined).Conclusions:The frontline medical workers are lack of experience in dealing with public health emergencies and have some psychological and working pressure. Administrative department should further complete the emergency plan of centralized isolation medical observation, strengthen the contingency management of public health emergencies, attach importance to the mental health of medical workers, optimize management methods and establish flexible work schedules.

Objective To explore the significance of NK cell activity,interleukin-2 receptors (sCD25) and glycosylated ferritin in the early diagnostic of acquired hemophagocytic lymphohistiocytosis (HLH).Methods 57 patients suspected of HLH from June 2005 to May 2008 and 25 healthy subjects were enrolled in the study.The patients suspected of HLH were divided into three groups i.e.(1) a group with diagnosis confirmed at first visit;(2) a group with diagnosis confirmed at subsequent visit and (3) a group with diagnosis unconfirmed according to HLH-2004 diagnostic criteria.Healthy subjects were enrolled as control.NK cell activity was determined with a released LDH assay.The percentage of glycosylated ferritin was determined with phytohemagglutinin adsorption assay,sCD25 was examined with ELISA double antibody sandwich assay.We compared the coincidence of each diagnostic index before and after diagnosis.Results The median percentage of NK cell activity was significantly lower in the first group ( 18.3±5.6) % and the second ( 16.7±6.7)% than that in the third group (33.4±6.8)% or in the controls (36.6±5.0)%.The median percentage of glycosylated ferritin was also significantly lower in the first group ( 15,4 ± 2.0)% and the second group (16.9 ± 3.4)% than that in the third group (40.4 ± 3.0)% or in the controls (45.2±2.2)%.Meanwhile,the median level of sCD25 was significantly higher in the first group (12 916±4328) ng/L and the second group (12 117 ± 5465) ng/L than that in the third group (4728±1482) ng/L or in the controls (3841 ± 993) ng/L.Furthermore,NK cell activity,sCD25 and glycosylated ferritin were abnormal in all the patients in the early stage of HLH.Conclusion NK cell activity,sCD25 and glycosylated ferritin may be helpful markers for the early diagnosis of HLH.

BACKGROUND: Acute graft versus host disease (aGVHD) is still one of the barriers of allogenic hemopoietic stem cell transplantation in clinic. It has been proven that transforming growth factor-beta1 (TGF-?1), tumor necrosis factor-? (TNF-?) and interferon-? (IFN-?) abnormal secretion may be essential factors for aGVHD. OBJECTIVE: To explore the role of interleukin-4 (IL-4) and IFN-?, marker factors of Th1 and Th2, in aGVHD mice model of allogenic hemopoietic stem cell transplantation. DESIGN, TIME AND SETTING: Randomized controlled in vivo transplantation was performed at Department of Animal, Beijing Stomatology Hospital and Department of Hematology, Beijing Friendship Hospital, Capital Medical University from August to October 2005. MATERIALS: Twenty clean-grade male C57BL/6(H-2b) mice as donors were selected for harvesting bone marrow cells and spleen lymphocyte; fifty BALB/c(H-2d) female mice as recipients were randomly divided into control group (n=10), bone marrow cell transplantation group (n=20) and combination transplantation group (n=20). METHODS: Bone marrow cell group was injected with 2.0?107 marrow cells through tail vein, and combination transplantation group was injected with bone marrow cells and spleen lymphocyte of C57BL/6(H-2b) mice. Both groups were exposed to 6MV-X radiation (9.0 Gy). MAIN OUTCOME MEASURES: Mice survival time; peripheral blood leucocyte count; cytokine levels in peripheral serum by ELASA; histopathological alterations by HE staining. RESULTS: Mice in marrow cell group died since the eighth day, while those in combination group since the fourth day. Kaplan-Meier exhibited P 0.05). Compared with marrow cell group, the levels of IL-4 were significantly decreased (P

Aim To observe the effects of flavonoids,including galangin(G),kaempferol(K),apigenin(A),morin(M),quercetin(Q) and myricetin(MY),on myocardial apoptosis induced by H2O2,and explore the possible mechanism.Methods Primary cultured cardiocytes of neonatal rat were randomly divided into normal group,model group,and flavonoids group.Fluorescent staining,electrophoresis and Western-blot were employed to observe the cardiocyte apoptosis and proteins expression.Results Exposure to 100 ?mol?L-1 H2O2 for 16 h resulted in myocardial apoptosis significantly(P

Objective To sum up the experience of position nursing of patients with ankylosing spondylitis and severe kyphosis. Methods Eleven patients with ankylosing spondylitis and severe kyphosis underwent surgery. The patients′spine and head were kept in a line during anesthesia to avoid spinal cord injury. The eye mask was used to make sure the eyelid close, so the bulbar conjunctiva and corneal did become dry. The angle of operation bed in time during operation was adjusted. The crushed area was observed and the position was changed to avoid pressure sores and edema. After surgery, they were keep inactive to make sure the spine stable and relieve the pressure. Results The 11 patients′surgery were successful. There were no pressure ulcer, fracture, spinal cord injury or eye injury occurs. The operation time was 9.3 ± 2.9 h. Conclusion Position nursing is very important to improve the success rate of surgery and reduce complications.

Objective To explore the effects of piperine on cell proliferation and migration in angiotensin Ⅱ (Ang Ⅱ)-treated rat airway smooth muscle cells (ASMCs).Methods The primary ASMCs of rats were cultured by improved tissue-piece digestion inoculation and trypsin digestion.MTT assay was used to detect the effects of Ang Ⅱ and Ang Ⅱ receptor antagonist losartan on cell proliferation activity.After treatment with Ang Ⅱ and piperine, the cell proliferation activity, the cell cycle distribution and the cell migration were detected by MTT, flow cytometry and Transwell assay respectively.ERK1/2 inhibitor PD98059 and losartan were then applied to determine the expression of cyclin D1, MMP-9, p-ERK1/2, ERK1/2, and β-actin proteins by Western blot assay.Results After 24 h culture, Ang Ⅱ treatment promoted the cell proliferative activity in rat ASMCs (P<0.05), and the promotive effect of 10-7 mol/L Ang Ⅱ was the most significant.Additionally, losartan blocked the Ang Ⅱ-induced cell proliferative activity in rat ASMCs (P<0.05).10-7 mol/L Ang Ⅱ treatment resulted in the elevated cell proliferative activity, higher S phase fraction, increased migrated cell number, and enhanced expression of cyclin D1, MMP-9and p-ERK1/2 proteins (P<0.05);these effects were dose-dependently reversed by piperine.Both PD98059 and losartan blocked Ang Ⅱ-induced expression of p-ERK1/2, cyclin D1 and MMP-9 proteins in rat ASMCs.Conclusions Piperine may inhibit Ang Ⅱ-induced cell proliferation and cell migration via ERK1/2 signaling pathway in rat ASMCs.

Objectives To investigate the clinical features,diagnosis,treatment and prognosis of primary hepatic lymphoma (PHL).Methods A retrospective study was carried out on the clinical records of 6 patients with primary hepatic lymphoma (PHL) treated at the Tianjin Medical University Cancer Hospital from April 2005 to September 2010.The domestic and foreign medical literatures were reviewed.Results For the 6 patients with PHL,the median age was 57 years (range 31-78 years).The male-to-female ratio was 2: 1.The most common initial symptoms were abdominal pain and fever.Serum transaminase,lactate dehydrogenase and β2-microglobulin levels were elevated in 4 of 6 patients.For the 3 patients who were tested for alpha-fetoprotein and carcinoembryonic antigen levels,the results were normal.None of the patients had a history of hepatitis or cirrhosis.The diagnosis was non-Hodgkin's lymphoma.A R0 resection was carried out in 1 patient who was lost to follow-up soon after surgery.A R2 resection was carried out in another patient.The remaining 4 patients received liver biopsy.Five patients were treated by CHOP or CHOP-like chemotherapy.A patient died of brain metastases after 8 cycles of chemotherapy,and another patient was lost to follow-up after 1 cycle of chemotherapy.Chemotherapy combined with rituximab were given to the other 3 patients.There was a complete remission in 2 patients after chemotherapy and biotherapy,and these patients were still alive at the last follow-up.Partial remission was achieved in the remaining patient after chemotherapy.The patient was given radiotherapy,but he died finally of tumor progression.Conclusions PHL is an extremely rare lymphoma.Its clinical presentations and imaging manifestations are non-specific.PHL should be considered when the patient has abdominal pain or fever,with a mass in the liver.The ultimate diagnosis depends on histopathologic examination.The pathological type is mainly non Hodgkin's lymphoma,with diffuse large B cell lymphoma.There is still no standard treatment.Surgery,chemotherapy,radiotherapy,targeted therapy and biotherapy can be used.
