Objective Developing an index system to evaluate the community teaching bases of general practice, for the purpose of identifying and completing at least one demonstration teaching base for general practice in each city in 2010. Methods Initial building of the index system by means of Delphi method and experts interview, followed by selection of experts for consultation, statistical analysis on the results of letter inquiries, and rounded up by the establishment of the index system for evaluation in the end. Results The recovery rates of a two-round Delphi questionnaire response are 94.12% and 100.00%respectively. Expert's authority degrees of five indexes are all over 0.8, which suggests high expert's authority. The average coordination coefficient of two-round Delphi experts consultation is 0.262and 0.534 respectively, showing good experts coordination. In the end, the study established four first-class indexes, ten second-class indexes, 41 third-class indexes and five additional indexes. Conclusions The index system is established in view of the current development of community teaching bases. It focuses on evaluating teachers, the teaching process and base's function. The evaluation system provides reference for selecting demonstration community teaching bases of general practice.

Objective To construct profiles of health status based upon physical,mental and social support items in adult twins of Qingdao.Methods Grade of Membership(GoM) model was applied to a set of 31 indicators to construct ideal profiles.Results Four health profiles were identified: pure type Ⅰ(healthy),pure type Ⅱ(personality disorders),pure type Ⅲ(psychological symptoms) and pure type Ⅳ(physiological symptoms).The most frequently occurring combination in this population was profile Ⅰ,Ⅱ,Ⅳ(14.74%),followed by profile Ⅰ,Ⅱ,Ⅲ,Ⅳ(13.44%),and then type Ⅰ(11.08%).Only 13.56% of subjects fell completely into one single pure type.Conclusions One healthy type and three non-healthy types are determined.Most individuals exhibit some of the characteristics of two or more types,holding partial membership in multiple categories.

OBJECTIVE:To study the effects of Dianxianqing granule on the interleukin(IL-6)content and glial fibrillary acid-ic protein(GFAP),ionized calcium linker molecules 1(Iba-1)expressions in hippocampus tissue of rats with kainate-induced epi-lepsy,and explore its mechanism of preventing and treating epilepsy. METHODS:Rats were randomly divided into sham operation group (distilled water),model group (distilled water),phenytoin group (0.03 g/kg,positive control) and Dianxianqing granule low-dose,medium-dose,high-dose groups(4.74,9.47,18.94 g/kg,calculated by crude drug),20 in each group. Rats were intra-gastrically administrated once a day,for 7 d. After 1 h of last administration,except for sham operation group,rats in other groups received single injection of kainite in hippocampus CA1 of left side to induce the epilepsy model. Behavioral changes and death of rats were observed. After 24 h of modeling,enzyme-linked immunosorbent method was used to detect the IL-6 content in hippocam-pus tissue of rats,Nissl staining was used to count the hippocampus neurons,and immunohistochemistry was used to detect the GFAP,Iba-1 expressions in hippocampus tissue of rats. RESULTS:Compared with sham operation group,rats in model group had obvious epilepsy symptoms after modeling,and parts of rats died;IL-6 content and number of neurons in hippocampus tissue were obviously decreased (P<0.01), while GFAP, Iba-1 expressions were obviously enhanced (P<0.01). Compared with model group,epilepsy symptoms and death in each administration group had improved,while IL-6 content in hippocampus tissue were in-creased to varying degrees,with no statistical significance (P>0.05). The numbers of neurons in phenytoin group,Dianxianqinggranule medium-dose, high-dose groups were obviously in-creased(P<0.01);GFAP expression was obviously decreased (P<0.01). Iba-1 expressions in hippocampus tissue in phenyt-oin group,Dianxianqing granule high-dose group were obvi-ously decreased (P<0.01). CONCLUSIONS:Dianxianqing granule can play the role in preventing and treating epilepsy by inhibiting GFAP,Iba-1 expressions in hippocampus tissue and in-creasing the number of neurons in hippocampus tissue.

Hemophilia encompasses a group of hereditary bleeding disorders characterized by impaired clotting factor activity,leading to prolonged clotting times.Patients display a tendency toward clotting issues following minor injuries,and severe cases may experience spontaneous bleeding.Acquired von Willebrand syndrome(AvWS)occurs due to the reduction of von Willebrand factor(vWF)levels,resulting in impaired platelet adhesion to endothelial cells,thereby compromising clotting function and leading to bleeding events.The increasing use of extracorporeal membrane oxygenation(ECMO)in clinical settings has brought attention to ECMO-related AvWS.During ECMO support,patients'blood exposure to high shear forces and non-physiological conditions can exacerbate the reduction of vWF levels,further impacting coagulation function.The precise mechanisms triggering AvWS during ECMO support are not conclusively defined,however,studies indicate that high shear forces and systemic inflammation response syndrome(SIRS)are key factors.Mechanical shear stress induced by ECMO damages endothelial cells,releasing factors associated with von Willebrand disease(vWD).Additionally,ECMO-induced SIRS may further compromise vWF functionality.Understanding these mechanisms is crucial for formulating effective preventive and treatment strategies.Diagnosing AvWS during ECMO support can be complex.Typically,assessing a patient's coagulation function and related factor levels is necessary,while cautious interpretation is vital due to potential ECMO interferences.Treatment strategies for managing AvWS during ECMO support are still under investigation.Some studies suggest that using plasma products may improve coagulation function.However,specific treatment approaches should be tailored to individual patient conditions and adjusted based on close monitoring.In summary,diagnosing and treating AvWS during ECMO support remains complex and challenging.Further research holds promise for better understanding the mechanisms involved and for developing more effective treatment strategies to enhance patient prognosis and quality of life.

Objective Neuromuscular electrical stimulation(NMES)-evoked kinesthetic information in muscle spindle can be purely extracted from the mixed motor and sensory afferents using Ischemic nerve block(INB).This study aims to investigate the somatosensory cortical response evoked by NMES activating muscle spindle afferents in forearm.Methods All subjects performed four experimental tasks designed according to a 2×2 factors,including one factor of the INB state(without INB and within INB)and the other of the stimulation intensity(above and below motor threshold).During the experiment,we recorded EEG data with 64 channels and then beta event-related desynchronization(Beta ERD)were utilized quantize somatosensory cortical excitability evoked by the tasks.The subjective perception about the sensation and movement of the right hand were evaluated by a psychophysical test after the right wrist was performed by INB.Results INB significantly reduced beta ERD on the contralateral somatosensory cortex evoked by NMES above the motor threshold,and there was significant difference of NMES-evoked beta ERD values on the contralateral somatosensory cortex between above and below motor threshold.Meanwhile,contralateral dominance of NMES-evoked beta ERD on the somatosensory cortex was transferred to ipsilateral hemisphere under INB.Conclusion INB can significantly reduce NMES-evoked somatosensory cortical response above motor threshold and decrease cortical perception on the stimulus intensity,which may be due to INB resulting in rapid functional reorganization of somatosensory cortex.

Objective To establish the murine models of local allergic rhinitis (LAR) and allergic rhinitis (AR) by using ovalbumin (OVA),and to investigate the relationship between them.Methods Thirty BALB/c mice were divided into 5 groups,(1) the nasally sensitized group (group A1) that was challenged with OVA by a 10 d procedure,(2) the control group of A1 that was challenged with phosphatebuffered saline (PBS),(3) the nasally sensitized group (group A2) that was challenged with OVA by a 25 d procedure,(4) the control group of A2 that was challenged with PBS,(5) the intraperitoneally sensitized group (group B).The numbers of sneezing after final challenge were counted,and the serum OVA-specific immunoglobulin E (OVA-slgE),interleukin (IL)-4,IL-13,IL-5 levels in nasal lavage fluid were measured by ELISA.Hematoxylin-eosin staining was performed to evaluate the histological change of nose and lung tissues.Graph Pad Prism 6 software was used to analyze the data.Results Nasally sensitized group A1 displayed LAR symptoms of sneezing and eosinophilic infiltrating,but without increased OVA-sIgE in serum on day 10 compared with the control group of A1(t =0.697,P ＞ 0.05),OVA-sIgE in serum of group A2(2.710 ± 1.406)ng/ml reached to statistical significance and with airway remodeling on day 25 compared with the control group of A2 ((0.221 ± 0.080) ng/ml,t =4.329,P ＜ 0.05).IL-5 and IL-13 in nasal fluid showed a significant increase in the nasally sensitized group A1,compared with the group A2 (t values were 2.442,2.804,P values were less then 0.05).Conclusions A short time intranasal instillation with OVA could establish LAR murine model,continuing OVA challenge could increase serum sIgE level and with airway remodeling.LAR mice show a unique characteristic by expressing higher IL-5 and IL-13 in nose than AR mice,but sIgE in serum remains at a normal level.
