Objective To explore the changes of CX3CR1 expressions in monocytes from the patients with different types of coronary heart diseases (CHD). Methods The expressions of CX3CR1 in monocytes were measured by direct immunofluorescence associated with flow cytometry (FCM) in 54 patients with stable angina pectoris (SAP) confirmed by coronary arteriography, 61 patients with acute coronary syndrome (ACS), 20 normal individuals and 24 patients with chest pain syndrome (CPS). Gensini score system was utilized to quantitatively assess the coronary lesion in CHD patients. Finally, the correlation of CX3CR1 levels and Gensini scores was analyzed. Results CX3CR1 expressions in monocytes from the CHD patients were markedly higher than those in normal individuals (P

Objective To assess whether mTOR was activated in peripheral T lymphocytes of acute coronary syndrome (ACS)patients and to investigate the relationship among mTOR,regulatory T cells and cytokins. Methods Patients with acute coronary syndrome (n=32) were selected in ACS group. Meanwhile, patients who complainted of chest pain but were proven to be normal in ECG and in coronary arteriography, were excluded as ACS patients but were diagnosed as Chest Pain Syndrome (CPS) and selected in CPS group (n=28). The expression levels of mTOR, phospho-p70S6KT389 (indicative of mTORC1 activity) and phospho-AKTS473(indicative of mTORC2 activity) were investigated in T cells, which were isolated from peripheral blood of patients in ACS group or CPS group, using Western blot. The proportion of CD4+CD25+Foxp3+Tregs over CD4+cells were evaluated by FACS. And T cell subset related cytokines such as IFN-γ, IL-4, IL-17 and TGF-β1 were exam?ined by ELISA. Then we investigated the relationship among mTOR,regulatory T cells and cytokins by Spearman analysis. Results mTOR and p-p70S6KT389 expression were significantly enhanced in ACS group as compared with those in patients from CPS group (P<0.01). Higher levels of IFN-γ, IL-17 but lower level of TGF-β1 cytokines as well as decreased propor?tion of Tregs were observed in ACS group than those in CPS group (P<0.05). There was no significant difference in the level of IL-4 and p-AKTS473 between the two groups (P>0.05). By correlation analysis, p-p70S6KT389 expression level positively correlated with IFN-γ, IL-17(rs=0.91,092,P<0.01)and negatively correlated with Tregs and TGF-β1(rs=-0.85,-0.80, re?spectively, P<0.01). Conclusion mTORC1 pathway was activated in peripheral T lymphocytes of ACS patients, and Tregs insufficiency and cytokins imbalance both contribute to the activation of mTORC1 pathway and pathological process of ACS.

Owing to climate influence, mean daily temperature in north China differs greatly from that of the southern regions during the same season. The introduction of Fritillaria thunbergii to Beijing for cultivation was hampered by delayed emergence of seedling and a shortened period for their growth, resulting in degeneration with the underground bulb becoming smaller year after year. With forcing culture as described in this paper, the emergence of seedling came earlier and growth period prolonged. The blossom and fruit became normal.By combining the method with formalin treated seed, diseases and pest index of the bulb were reduced distinctly and the yield increased with increased proportion of larger bulb year after year.

By means of HPLC,the changes of endogenous hormones in the process of releasing dormancy in Fritillaria thunbergii Miq. seeds were determined. The results indicated that the content of GA3 had a process of increase while the content of ABA was reduced in general. The content of IAA showed a downward -plateau-upward-downward curve in the process of releasing dormancy. When the dormancy of the seeds were released attemperatures 8~10℃ and 3~5℃,changing pattern of each of the three endogenous hormones were similar,but the duration spanning each change were different.

Objective To investigate the effects of co-exposure to LPS and heat on plasma tumor necrosis factor-? (TNF-?), interleukin-6 (IL-6), malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in rats. Methods Male pathogen-free Wistar rats were randomly assigned to the following groups: saline-injected normothermic control (Group C), saline-injected heat exposure (Group H), LPS-injected normothermic control (Group L), LPS-injected heat exposure (Group HL). Mean arterial pressure (MAP) was continually monitored. Plasma levels of TNF-?, IL-6, MDA and SOD were determined at 0, 40, 80, 120 min. Results The rats in Group HL displayed much lower MAP, higher MDA and lower SOD than the other 3 groups. The rats in Group HL displayed an early rise in plasma TNF-?, IL-6 at 40 min, the peak values of both at 80 min significantly higher than the other three groups at the same time piont. Conclusion Co-exposure to LPS and heat primes the rats to advance and augment systemic inflammatory response syndrome.

0.05).Follow-up coronary angiography was more frequently performed in group A than in group B.Conclusion In patients with acute myocardial infarction treated with primary percutaneous coronary intervention,the transradial approach is a safe and feasible technique.With the higher rate of follow-up angiography,it was found that the incidence of MACE at 1-month follow-up and 6-month follow-up using the transradial approach was similar to transfemoral approach.Therefore,the transradial approach is expected to become the substitute approach for treatment in AMI patients.

Objective To study the clinicopathologic features of giant cell carcinoma of the pancreas(GCCP). Methods The clinicopathologic features of 19 pathologically diagnosed as GCCP were retrospecti- vely analyzed in detail, compared with 96 cases of common pancreatic carcinoma (PC). Results Tumors that occurred in the head of pancreas were found in 8 patients(42.1%), and those in the body or tail of pancreas in 11 patients(57.9%). The initial symptom is mainly characterized by abdominal pain (57.9%). Abdominal pain (73.7%), dyspepsia(63.2%) and weight loss(36.8%) were common symptoms when patients were diagnosed. Jaundices is not a common symptom in these patients. The abnormal rates of routine laboratory tests were dramatically lower than those in common PC. The assay of tumor markers between GCCP and common PC were approximately same. The sensitivity and accuracy of diagnosis by ultrasonography, spiral computed tomography and magnetic resonance imaging were high. The carcinomas grew so large that 9 patients ( 47.4%)were in stage Ⅳ, the rate of which was higher than that in common PC. Osteoid formation was found under microscopy in some patients, and the tumor cells differentiated poorly in most of patients. The overall 1-year survival rate was 17.6%, which was lower than that in common PC. Conclusions The clinicopathologic features of GCCP are different from those of common PC. Imaging tests may be combined with the assay of tumor markers simultaneously so as to diagnose GCCP as early as possible and thus the prognosis of GCCP patients could be improved.

OBJECTIVE:To investigate the effects of tiotropium bromide assisted with bronchoalveolar lavage (BAL) on short-term efficacy,quality of life and re-hospitalization rate of patients with bronchiectasis complicated with lung infection. METH-ODS:A total of 140 patients with bronchiectasis complicated with lung infection selected from our hospital during Oct. 2013-Dec. 2015 were divided into control group and observation group by lottery,with 70 cases in each group. Based on intervention therapy, control group received BAL. Observation group was additionally given Tiotropium bromide powder inhalation 18 μg ,once a day before going to bed,on the basis of control group. Both groups were treated for 4 weeks. Clinical efficacy was compared between 2 group;pulmonary ventilation function indexes,blood gas analysis indexes,BODE index scores and QLI scores before and after treatment,re-hospitalization rate and the occurrence of ADR were also compared between 2 groups. RESULTS:The total response rate of observation group was 91.43%,which was significantly higher than that of control group(78.57%),with statistical signif-icance (P<0.05). Before treatment,there was no statistical significance in pulmonary ventilation function indexes,blood gas analysis indexes,BOED index scores or QLI scores between 2 groups(P>0.05). After treatment,FVC,FEV1,FEV1%,p(O2) and QLI score of 2 groups were increased significantly,while p(CO2)and BODE index scores were decreased significantly,com-pared to before treatment;all indexes of the observation group was significantly better than the control group,with statistical sig-nificance (P<0.05). The re-hospitalization rate of observation group 3,6 months after treatment was significantly lower thanthat of control group,with statistical significance(P<0.05). No ADR was found in 2 groups. CONCLUSIONS:For patients with bronchiectasis complicated with lung infection,tiotropium bromide assisted with BAL can effectively relieve the clinical symp-toms and signs,improve lung ventilation function and the quality of daily life and can be helpful to reduce the risk of re-hospital-ization with good safety.

Objective To investigate the effect of HPA gene polymorphism and its alleles on platelet transfusion.Methods From January 2015 to January 2017,50 patients suffered from Platelet transfusion refractoriness were collected as an observation group while 50 patients without Platelet transfusion refractoriness were collected as a control group.The HPA gene polymorphism of the both groups were compared.Results When compared with the control group,the HPA type coincidence rate of Donor and recipient in the observation group decreased significantly (4.00％ vs.82.00％,P =0.000).And patients in the observation group got decreased levels of percent platelet recovery and platelet corrected growth index.(HPA16,9,15) were common in both groups.However,aa,ab and bb of the HPA-2 allele got 37,8 and 5 cases in the observation group,while there were 48,2 and 0 cases in the control group (P=0.007).And aa,ab and bb of the HPA-3 allele got 33,9 and 8 cases in the observation group,while there were 46,3 and 1 cases in the control group (P =0.005).Moreover,aa,ab and bb of the HPA-15 allele got 35,8 and 7 cases in the observation group,while there were 47,2 and 1 cases in the control group (P =0.007).Homozygous aa were the most common gene type in the donors of the both groups,and the difference was no statistically significant (P＞0.05).As aa,ab and bb of the HPA-2,3 change,the percent platelet recovery and platelet corrected growth index both decreased (P＜0.05).Conclusion Platelet transfusion refractoriness is related to HPA gene polymorphism,and allele b may be the cause of platelet transfusion refractoriness.

Objective] The pathogenesis of HuangQin Tang is discussed little in six meridians syndrome differentiation, and which meridian syndrome does it belong to isn’t clear. So this article tries to discuss the belonging and pathogenesis of it. And the key point of using it in clinic will also be involved.[Method] Combining the observation of efficacy of XiaoChaiHu Tang and HuangQin Tang and the elaboration articles are related to that two prescriptions to analyze the difference of that two prescriptions in pathogenesis.[Result]It’s found that HuangQin Tang and XiaoChaiHu Tang all belong to ShaoYin in six meridian syndrome.But their pathogenesis is different. HuangQin Tang should be used in heat syndrome of ShaoYang disease which caused by heat pathogen of ShaoYang meridian and diarrhea will appear because belly is shocked. However, XiaoChaiHu Tang is used to drive cold pathogen of ShaoYang meridian. [Conclusion]Both of HuangQin Tang and XiaoChaiHu Tang belong to ShaoYang Meridian, but it’s known that HuangQin Tang is used less. And less discussion of HuangQin Tang should be blamed. The more we know on pathogenesis of HuangQin Tang, the better we use it.
