Objective To observe the influence of different extraction technologies on baicalin content in QinShao tablet. Methods Determine the changes of baicalin content in two different decocting methods: 1 to decoct Baical Skullcap Root together with other Chinese medicines, and 2 to decoct Baical Skullcap Root after other medicines. Results The result showed the later decocting method (decoct baical skullcap root later) can increase the content of baicalin by 5.2mg/g. Conclusion To decoct Baical Skullcap Root after other medicines in QinShao tablet can increase the content of baicalin and thus enhance its clinical therapeutic effects.

Objective:To investigate the effect of long-term alcohol intake on sensory information synaptic transmission of mossy fiber-granular cells in the cerebellar cortex of mice.Methods:Twenty healthy male ICR mice aged 6 to 8 weeks were divided into normal saline group(control group) and alcohol intake group(alcohol group) according to random number table, with 10 mice in each group. The mice in alcohol group were injected intraperitoneally with 20% alcohol and the mice in control group were injected with the same amount of saline for 28 days.After the injection, the scalp, muscle tissue and skull were removed in turn, and the dura mater was removed to fully expose the crus II area of cerebellum. The mice were stimulated by air blowing at 30 mm of the ipsilateral tentacle pad with a gas jet device.When the the maximal response site was determined, the NMDA receptor antagonist (D-APV), metabolic glutamate receptor 1 antagonist (JNJ16259685) and N-methyl-D-aspartic acid (NMDA) were perfused on the brain surface of mice. Each drug was perfused for 20 minutes and ACSF was used between the two drugs until the waveform was recovered. Patch clamp amplifier was used to record the changes of potential waveform in mouse cerebellar granule layer. The data were analyzed by the softwares of Clampfit 10.3 and SPSS 22.0.Results:After exposure to wind stimulation, the latency of field potential response in granular layer of mice in alcohol group (11.8±0.7)ms was significantly longer than that in the control group (10.1±0.2)ms ( t=-8.041, P<0.05), and the amplitude of N1 (1.2±0.1) MV was significantly lower than that in the control group (0.6±0.1) MV ( t=-12.728, P<0.05). Compared with the control group, the rise time of P1 waveform((4.4±0.2)ms, (3.2±0.2)ms), duration ((12.1±0.5)ms, (10.3±0.2)ms), extinction time((7.8±0.2)ms, (6.9± 0.2)ms), volume under waveform ((7.3±0.2)ms, (4.3±0.2)ms) were significantly increased in the alcohol group ( t=16.100, - 11.840, -11.673, -35.576, all P<0.05). There were no significant differences in the amplitude, half width, rise time and decay time of Roff wave between the two groups ( t=-1.909, -0.910, -0.789, 1.462, all P>0.05). When JNJ16259685 was perfused on the brain surface of mice in alcohol group, the amplitude of field potential evoked by five blowing stimuli had no significant difference compared with that before administration (all P>0.05). When D-APV was perfused into the brain surface of mice in the alcohol group, the amplitude of P1 ((42.3±1.5) Mv)was significantly lower than that before administration ((101.1±0.9)mV) and after elution ((100.1±2.2) mV) ( t=106.762, - 69.605, both P<0.05), and the area under waveform of P1 ((42.6±1.3)%) was also significantly lower than that before administration ((100.6±1.6)%) and after elution ((97.6±2.2)%) ( t=88.862, -67.791, both P<0.05).The ratio of N2 / N1 (0.3±0.1) was significantly lower than that before administration (0.4±0.1) and after elution (0.3±0.1) ( t=2.242, 2.121, both P<0.05). When NMDA was perfused on the brain surface of mice in the control group, compared with before administration and after elution, the amplitude of P1 ((110.7±3.2) mV, (100.1±0.9) mV, (102.0±1.7) mV, t=-10.173, 7.669, both P<0.05), the area under the waveform of P1 ((127.9±3.5)%, (100.0±3.1)%, (115.0±5.3)%, t=-18.698, 6.447, both P<0.05), the ratio of N2 / N1 ((0.5±0.1), (0.3±0.1), (0.3±0.1), t=-5.669, 5.669, both P<0.05) were all significantly increased. When D-APV was perfused on the brain surface of mice in control group, the field potential evoked by blowing stimuli had no significant difference compared with that before administration and after elution (all P>0.05). Conclusion:Long-term alcohol intake significantly suppresses the synaptic transmission of excitatory glutamate in MF-GC, and enhances the inhibitory response mediated by GABAA receptor in cerebellar cortex. The inhibitory component is enhanced by NMDA receptor, but not by type 1 metabolic glutamate receptor.

Objective To study the clinicopathologic features,diagnosis and differential diagnosis of tumors of haematopoietic and lymphoid tissue in the female productive tract. Methods Eleven cases of myeloid sarcoma and leukemia, 9 of non Hodgkin lymphoma(NHL),13 of cervical lymphoma-like lesions were selected from Peking University People′s Hospital from January 2006 to August 2017. According to WHO classification of tumors of haematopoietic and lymphoid tissues(2008)and updated classification(2016),the cases were studied by microscopy,immunohistochemistry and in situ hybridization.Results In 20 cases of tumors of haematopoietic and lymphoid tissue,the mean and median age was 48.5 and 56 years old(range:16-77 years old).In cases of lymphoma-like lesion of uterine cervix,the mean and median age was 45.9 and 48 years old(range:23-62 years old).The patients with neoplasm present as fever,fatigue, hypogastralgia, colporrhagia and mass etc. Eight cases had history of acute myeloid leukemia, and 3 had myeloid leukemia while pregnancy. One case of chronic lymphocytic leukaemia/small lymphocytic lymphoma(CLL/SLL)had history of ovary small cell carcinoma and high grade serous carcinoma resected with chemotherapy.One case of diffuse large B cell lymphoma(DLBCL)had history of renal transplantation. Lactic dehydrogenase(LDH)was elevated in 9 cases(9/18).The cases of lymphoma-like lesion present as contact bleeding in most cases and all located in cervix. Four cases of neoplasm located in vulva, 1 in vagina,4 in cervix, 4 in uterine corpus, 8 in ovary and 2 in placenta.Clinical staging of NHL: 4 case was stageⅠ,1 case of stageⅢ,and 4 cases of stageⅣ.Pathological morphology:9 cases were myeloid sarcoma, 2 cases were placenta invaded by myeloid leukemia. Six cases were DLBCL, and 1 case was CLL/SLL, 1 case was mucosa associated lymphoid tissuse lymphoma(MALToma), and 1 case was anaplastic large cell lymphoma. Resected mass, chemotherapy was performed in tumors of haematopoietic and lymphoid tissue. Five cases of myeloid sarcoma and 2 of NHL died. In 13 cases of lymphoma-like lesion of uterine cervix, the general condition was good as following up. Conclusions The clinical history, pathological morphology and immunohistochemistry are very important for diagnosing tumors of haematopoietic and lymphoid tissue in the female productive tract.Resection with chemotherapy is recommended in treatment. The prognosis of lymphoma-like lesion of uterine cervix is good,and should be differentiated from lymphoma.

Aiming at the current situation of insufficient integration of medical humanities teaching and clinical practice， as well as the need for further research and improvement in the teaching system， guided by the concept of medicine and humanistic literacy integration advocated by the new medical science， this paper deeply discussed the construction of clinical medical humanities teaching system from four aspects， including the selection of clinical medical humanities teachers and team building； the teaching path that combines theoretical education， narrative medicine， and clinical skill training infused with medical humanities content； curriculum ideological and political construction with the goal of establishing the core concept and value orientation of “patient-centered”； the teaching assessment and evaluation method characterized by formative evaluation. The clinical medical humanities teaching system emphasizes the practicality， experiential， and emotional aspects of medical humanities teaching， deeply integrating medical humanities with clinical practice teaching content throughout the clinical internship period of medical education， with a view to enhancing the humanistic practice ability and literacy of medical students.
