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 To investigate the effect of early coronary artery bypass grafting (CABG)to the left ventricular wall motion state and the significance of CABG to awake hibernating myocardial in dogs with acute myocardial infarction.Methods The anterior descending coronary of all thirty dogs were ligated into MI model.According to the operation date,the experimental groups included the 1 st week (n =6),the 2nd week (n =4),the 4th week (n =6) and the 6th week (n =6) CABG,and established control group (n =2) for every experimental group.Operators marked hibernate myocardial and determined the room wall motion score by means of dobutamine ultrasound load test (DSE) combining with tissue doppler imaging (DTI)technology before CABG and after eight weeks CABG through thoracotomy surgery for the experimental group and the control group.Every dog was executed and detected the area of MI.Results Four dogs of experimental group and all dogs of control group survived to the end of the study.The change of ventricular room wall motion score in the 1st and the 2nd week CABG was smaller than that in the 4th and the 6th week CABG and MI group(0.03 ±0.06,0.05 ±0.09,0.23 ±0.08,0.27 ±40.06,0.32 ±0.05,P ＜0.05).The change of room wall motion score in all CABG groups was smaller than that in MI group(1.195 ±0.09,1.25 ±0.18,1.30 ±0.18,1.36 ±0.11,1.65 ±0.17,P＜0.05).The hibernate myocardial were more awaken in all CABG groups than that in MI group (0.27 ± 0.12,0.22 ± 0.04,0.31 ± 0.09,0.23 ± 0.03,0.03 ± 0.04,P ＜ 0.05).The area of MI became smaller in 1 and 2 weeks CABG than that in 4 and 6 weeks CABG and MI group(20.75 ± 2.63,21.25 ± 2.5,27.25 ± 1.71,27.75 ± 2.22,P ＜ 0.05).Conclusions Early CABG surgery for dogs acute MI could improve the ventricular room wall motion obviously and wake up more hibernate myocardial.Especially,CABG surgery among two weeks could lessen the effect of MI to the ventricular room wall motion and reduce the scope of myocardial infarction maximatily.

Objective: To establish a hypertension risk assessment model among the middle-aged and elderly populations based on residents' electronic healthcare records of the basic public health service program, so as to provide insights into prevention of hypertension. Methods: Demographic features and physical examinations were collected among residents at ages of 40 years and older from residents' electronic healthcare records of the basic public health service program in a county of Zhejiang Province from 2019 to 2020. The risk factors of hypertension were identified using a multivariable logistic regression model, and the odds ratio (OR) for each risk factor was transformed into approximate relative risk (RR), which was included in the formula for calculation of the disease risk proposed by Harvard School of Public Health to create a hypertension risk assessment model. The predictive value of the model was evaluated using a receiver operator characteristic (ROC) curve. Results: Totally 7 275 subjects were enrolled, with a mean age of (66.15±7.91) years, and the participants included 3 189 males and 4 086 females, with a male-to-female ratio of 0.78∶1. There were 190 cases with new-onset hypertension (2.61%). Multivariable logistic regression analysis revealed that overweight, obesity, central obesity, borderline high triacylglycerol (TG), elevated TG, abnormal fasting plasma glucose (FPG), prehypertension and family history of hypertension were included in the hypertension risk assessment model, with approximate RR values of 1.66, 1.96, 1.54, 1.17, 1.64, 1.45, 1.69 and 1.11. The area under the ROC curve (AUC) of the model was 0.678 (95%CI: 0.641-0.715, P<0.001), and the optimal positive cut-off was 0.899. The model predicted 139 subjects with RR>0.899 for hypertension, with a sensitivity of 73.16% and specificity of 55.79%. Conclusions The hypertension risk assessment model created in this study is feasible to predict the RR for developing hypertension among the middle-aged and elderly populations, which has a predictive value in healthcare management.

OBJECTIVETo summarize the management of infant vascular tumors with Kasabach-Merritt phenomenon (KMP) and to evaluate the effect of drug combined with sclerotherapy.

METHODSFrom Feb. 2007 to Nov. 2014, 25 cases with KMP, who underwent drug therapy combined with sclerotherapy, were retrospectively studied. Oral corticosteroids (2 mg/kg per day) was used as the first-line therapy on all of the patients and intravenous vincristine (1.5 mg/m2 every week) was added when the platelet counts didn't recover obviously after 2-3 weeks. After the recovery of the platelet counts, the patients were admitted for sclerotherapy (average, 4.56 sessions per case) with 100% alcohol (1-3 ml per session), Lauromacrogol (1.25-5 ml per session) and betamethasone (0.25-1 ml per session). All the patients were followed up for 42 months ( range, 9 months to 6.5 years). Therapeutic outcomes were assessed by evaluating platelet counts, size of lesion, function of trunk and limb.

RESULTSAll the 25 cases got obvious recovery in the platelet counts [average, (94.3 ± 18.5) x 10(9)/L] after drug therapy, of which 16 were treated by single oral corticosteroids for 4-7 weeks and 9 were treated by corticosteroids plus intravenous vincristine for 2-5 weeks. Meantime, 11 cases received platelet transfusions, of which 3 were coupled with gamma globulin intramuscularly. During the first admission, each of the 25 cases received 1-4 sessions of sclerotherapy (average, 2.6 sessions each case). One week after the sclerotherapy, the platelet counts returned to (167-312) x 10(9)/L (average, (258.5 ± 34.4) x 10(9)/L). The hemoglobin and blood coagulation function returned to normal within 1-5 weeks. Meanwhile the mental condition, appetite, body weight, sleeping were greatly improved. The size of the lesions decreased gradually after the combined therapy including 13 cases within 3-12 months and 13 cases within 13-36 months. Long term follow-up indicated that only 1 case need treatment for recurrent decrease of platelet counts, and all of the 25 cases kept the normal weight, height, immunity as well as the growing development.

CONCLUSIONSOral corticosteroids plus intravenous vincristine combined with sclerotherapy is a reliable management with high cure rate, short course and minor side-effect.

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.
