Objective To explore application value of combined detection of procalcitonin(PCT ) and high‐sensitivity C‐reactive protein (hs‐CRP) in clinical diagnosis of infectious diseases .Methods 162 cases of hospitalized patients with infectious diseases from June 2012 to December 2014 were enrolled in this study and divided into bacterial infection group(92 cases)and viral infection group (70 cases) according to the results of isolation and culture of pathogen and virus antibody detection .Other 100 cases of healthy individuals were selected as healthy control .The serum levels of PCT and hs‐CRP were detected by using immunochroma‐tography and immunofluorescence assay respectively and were statistically analysed .Results The serum levels of PCT and hs‐CRP in the bacterial infection group were higher than those in the healthy control group ,the differences were statistically significant (P<0 .05) .The serum levels of PCT and hs‐CRP in the viral infection group were higher than those in the healthy control group , but only the difference of hs‐CRP between the two groups was statistically significant(P<0 .05) .In patients with bacterial infection and viral infection ,the positive rates of combined detection of hs‐CRP and PCT were higher than single detection of hs‐CRP or PCT ,the differences were statistically significant(P<0 .05) .Conclusion PCT and hs‐CRP could be important serum markers of bacterial infections ,combined detection of the two markers have clinical significance for diagnosing infectious diseases and assessing its prognosis .

Objective The purpose of the experiment is to research the effects of different kind of anti-platelet drugs and their combinations in prevention of vascular restenosis after ballon-injury, and to evaluate the best way of clinical utility of anti-platelet drugs.Methods Fifty-six male New Zealand White Rabbits were randomly assigned to 3 groups: the control group (ML) , the model group (M) , the experimental group.The experimental group was divided to 5 subgroups, the aspirin group (A), the cilostazol group (B) , the clopidogrel group (C), the aspirin plus cilostazol group (A + B) , and the aspirin plus colopidogrel group (A + C).Femoral artery stenosis model was induced by halloon injury except the control group.The rabbits were fed different drugs 3 days before operation except the normal group and the model group.On the 14th day after operation, the rabbits were sacrificed and the iliofemoral arteries were removed and made to the pathological section.We measured the internal elastic lamina, external elastic lamiua and luminal areas measured.Then calculate the area of intima, media and the ratio of intima vs.media.Results ①There is no endothelium hyperplasia in control group.Compared with the control group, we observed endothelium hyperplasia in both model group and the experimental groups.Compared with the model group, endothelium hyperplasia in all experimental groups is in a lower degree;② Cilostazol alone works better than aspirin alone and clopidogrel alone in prevention of vascular restenosis after ballon-injury.Clopidogrel combined with aspirin and cilostazol combined with aspirin both work better than aspirin alone in prevention of vascular restenosis after ballon-injury.There is no apparent difference between the effect of clopidogrel combined with aspirin and cilostazol combined with aspirin.Conclusions ① Different anti-platelet drugs and different combinations of them can prevent the happening of vascular restenosis after ballon-injury.② Cilostazol works better than aspirin and clopidogrel in prevention the happening of vascular restenosis after ballon-injury, and combination of anti-platelet drugs which contains cilostazol works better than other way of combination of anti-platelet drugs.③ Cilostazol and combination of anti-platelet drugs which contains cilostazol is potential useful in clinical uses to prevent restenosis after PTA.

Jasmonic acid (JA), a plant endogenously synthesized lipid hormone, plays an important role in response to stress. This manuscript summarized the biosynthesis and metabolism of JA and its related regulatory mechanisms, as well as the signal transduction of JA. The mechanism and regulatory network of JA in plant response to biotic and abiotic stresses were systematically reviewed, with the latest advances highlighted. In addition, this review summarized the signal crosstalk between JA and other hormones in regulating plant resistance to various stresses. Finally, the problems to be solved in the study of plant stress resistance mediated by JA were discussed, and the application of new molecular biological technologies in regulating JA signaling to enhance crop resistance was prospected, with the aim to facilitate future research and application of plant stress resistance.

Objective    To summarize the perioperative outcome of patients undergoing robot-assisted thoracic surgery (RATS) or four-port single-direction video-assisted thoracic surgery (VATS) right upper lobectomy (RUL), and to discuss the safety and the essentials of the surgery. Methods    The clinical data of 579 patients with non-small cell lung cancer (NSCLC) undergoing minimally invasive RUL in Dr. Luo Qingquan’s team of our center from 2015 to 2018 were retrospectively analyzed. There were 246 males and 333 females aged 33-78 years. The 579 patients were divided into a RATS group (n=283) and a VATS group (n=296) according to surgical methods. Baseline characteristics and perioperative outcomes including dissected lymph nodes, postoperative duration of drainage, postoperative hospital stay, postoperative complications and surgery cost were compared between the two groups. Results    There was no significant difference in baseline data between the two groups (P>0.05), and no postoperative 30 d mortality or intraoperative blood transfusion was observed. Compared with VATS, RATS had shorter operation time (90.22±12.16 min vs. 92.68±12.26 min, P=0.016), postoperative hospital stay (4.67±1.43 d vs. 5.31±1.59 d, P<0.001) and time of drainage (3.55±1.38 d vs. 4.16±1.58 d, P<0.001). No significant difference was observed between the two groups in the lymph nodes dissection, blood loss volume, conversion rate or complications. The cost of RATS was much higher than that of VATS (93 275.46±13 276.69 yuan vs. 67 082.58±12 978.17 yuan, P<0.001). Conclusion    The safety and effectiveness of robot-assisted and video-assisted RUL are satisfactory, and they have similar perioperative outcomes. However, RATS costs relatively shorter operation time and postoperative hospital stay.
