Objective To explore the value of applying multiple disciplinary team (MDT) in the clinical practice teaching of lymphoma. Methods 5-year program clinical medicine undergraduate students of 2012 were divided into experimental and control group randomly, with 30 cases in each group. The ex-perimental group received MDT in clinical teaching through MDT conference and cases analysis. The control group received conventional teaching mainly by smal class presentation and ward round . The effect of teaching was evaluated by examination and questionnaire. The data were analyzed through t-test and chi-square test by SPSS 20.0 software. Results The results showed the students' scores of the theory knowledge test of two groups were similar to each other, but the scores of discussional topic and clinical cases analysis were higher in experimental group than control group and statistically difference [(16.5 ±2.3)vs. (10.5 ±1.8);(37.5±2.5) vs.(27.5±1.8)], (P=0.000), and the final score of two groups showed statistically difference (93.5± 5.2 vs. 76.0 ±6.2) (P=0.000). Meanwhile, questionnaire survey of satisfaction showed that 27 students of experimental group (90.0%) were interested in this new teaching model, 29 students (96.7%) believed it im-proved understanding and memory to the process of lymphoma diagnosis and treatment, 25 students (83.3%) believed it could improved the ablility to diagnose and differential diagnose lymphoma and expanded their clinical view. 28 students (93.3%) had consolidated clinical thinking, and 26 students (86.7%) improved negotiation with patients. All issues were significantly better than control group (P<0.05). Conclusions The clinical teaching model innovation based on MDT could help medical students use the cross-discipinary interviewing and make optimal treatment plan for patients. It is conducive to the cultivation of their diagnosis, differential diagnosis and clinical thinking ability, which is worthy of promotion in hematological clinical teaching.

This study was aimed to determine the solubility an d oil-water partition coefficient of main active com-ponents in Ge-Gen Qin-Lian (GGQL) Tablets (puerarin, baicalin and berberine hydrochloride) in phosphate buffer solution of different pH values and under the background of many components. Solubility of puerarin, baicalin and berberine hydrochloride in different medium pH, and oil-water partition coefficient of the octanol-water and oc-tanol-buffer system were determined by HPLC method. The results showed that the solubility and oil-water partition coefficient of puerarin, baicalin and berberine hydrochloride were varied with the change of pH, and varied under the background of components. At pH 7.4, the solubility was the biggest;puerarin was 7.56 mg·mL-1;baicalin was 17.07 mg·mL-1; berberine hydrochloride was 3.57 mg·mL-1. Oil-water partition coefficient P of these components at pH 1.0 was bigger;puerarin was 0.420 (lgP=-0.38);baicalin was 10.783 (lgP=1.03);berberine hydrochloride was 0.267 (lgP=-0.57). It was concluded that lipid solubility of puerarin, baicalin and berberine hydrochloride at pH 1.0 was better. It was speculated that better absorption in the stomach, and low lipid solubility under other pH. It was speculated that lipid solubility may be one of the reasons affecting the intestinal absorption.

Objective To evaluate the outcome of ST-segment elevation myocardial infarction (STEMI) patients received different reperfusion therapies. Methods The 238 consecutive STEMI patients were enrolled from February 2012 to December 2012. According to the current guideline of PCI and the choice of patients, the patients were divided into the groups of percutaneous coronary intervention (PCI), ifbrinolysis, and conservative medication. The major adverse cardiac events (MACE) was analyzed in a follow up of 6 months. Results (1) The enrolled patients included the 210 patients received PCI (88.2%), 14 patients received fibrinolysis (5.9%) and 14 patients received conservative medication (5.9%).The Median time of D2B was 110minutes.(2) The rate of late stent thrombosis was signiifcant higher in BMS than DES (n=2, 2.8%vs 0, P < 0.05) . (3) The PCI group had a signiifcantly higher incidence of stroke than the ifbrinolysis group and the conservative medication group (1.0%vs 0, P < 0.05;1.0%vs 0, P<0.05). (4) The PCI group had a signiifcantly higher incidence of bleeding compared to the thrombolysis group and the medication group (1.0% vs 0, P < 0.05; 1.0% vs 0%, P < 0.05). Conclusions The majority of STEMI patients received PCI;The D2B time, which was required<90 minutes in guideline of PCI, was found delayed in our study;Compared to ifbrinolysis and conservative medication, PCI showed better clinical outcomes of STEMI patients.

Objective To investigate the clinical characteristics, curative effect and prognosis of myeloid sarcoma. Methods The clinical data of 12 patients with MS diagnosed at Xijing Hospital of Air Force Medical University from August 2008 to May 2018 were retrospectively analyzed. Their clinical manifestations, diagnosis, treatment and survival were analyzed. Results Twelve patients were 17 to 62 years old. The initial site included lymph node, external auditory canal, eye, buttock, lung, liver, pancreas, breast,skin, vertebra and its surroundings,and cervix. Among 11 patients with peripheral blood classification, bone marrow aspiration and bone marrow biopsy, 6 cases were isolated MS [one of which developed acute myeloid leukemia (AML)], 1 case was chronic myeloid leukemia in chronic phase, 2 cases were AML-M2, and 1 case was myelodysplastic syndrome (MDS), and 1 case was after aplastic anemia (AA) with no infiltration of bone marrow. Immunohistochemical results showed that LCA(+) (7/7), MPO(+) (12/12), CD43(+) (9/9), lysozyme(+) (5/7), CD3(-) (8/8), CD20(-) (9/9), CD34(+) (5/6), CD117(+) (7/7), and Ki-67(+) 30%-90%. Four patients were examined for bone marrow chromosomes, 2 patients with AML had t (8;21), 1 patient with MDS was 47, XX, +8, del(11)(q21), and 1 patient with CML was t(9;22). Two of the 12 patients were lost to follow-up. Among the 10 patients who were followed up, 6 died and 4 survived, and the median survival time was 21 months (2-27 months). Conclusions AA in stable phase with MS and CML in chronic phase with MS are rarely reported. The clinical manifestations of MS patients are varied, of which the common incidence sites are superficial lymph nodes, the infrequent sites are vertebra and its surrounding areas, and the rare sites are eye, pancreas, lung, liver, etc. The median survival time of MS patient is short and the curative effect is poor.

Objective: To develop a new method for the determination of calcipotriol ointment by high-speed counter-current chro-matography(HSCCC). Methods: An HSCCC method was used coupled with two-phase solvent system consisting of petroleum benzine-ethanol -water(2: 1: 0. 5, v/v/v). The injection volume was 1. 0 ml and the detection wavelength was set at 265 nm. Results: The proposed method showed good linearity within the range of 4.02-40.20 μg·ml-1(r=0.999 4). The average recovery was 99.2%, and the RSD was 0. 4% (n=9) . Conclusion: The HSCCC method is simple and rapid, and suitable for the determination of calcipo-triol ointment.

Objective To investigate the expression of bone marrow γ-H2AX in the patients with multiple myeloma(MM) and its correlation with the prognosis.Methods The patients with newly diagnosed MM in this hospital were selected as the case group,and the patients with non-hemopoietic system tumor without obvious morphological abnormalities by bone marrow smear and biopsy served as the control group.The immunohistochemistry was adopted to detect the expression level of bone marrow γ-H2AX in the cases group and control group,the image-Pro Plus(IPP) semiquantitative analysis was performed.The expression differences were compared between the two groups,moreover the case group was re-divided into the strong expression group and weak expression group according to γ-H2AX expression level.Then the relation ship between γ-H2AX expression level and the prognosis in the patients with MM.Results The bone marrow γ-H2AX expression level in the case group was significantly higher than that in the control group (P＜0.05);the level of γ-H2AX expression in the strong expression group was significantly stronger than that in the weak expression group (P＜0.05).Conclusion The level of γ-H2AX expression was higher among MM patients,and the over expression of γ-H2AX predicts the shorter survival time.
