Objective To follow up long-term clinical events and compare the long-term prognosis between partial and complete revascularization in octogenarians with coronary artery disease.Methods A total of 108 patients aged 80-88 years who underwent elective percutaneous coronary intervention (PCI) in cardiology department of Huashan Hospital were divided into complete revascularization group (n=47) and partial revascularization group (n=61).They were followed up for long-term major adverse cardiovascular events from Jan.1 2005 to Dec.31 2008.Results There were no statistically significant differences in age,percent of female,prevalence of hypertension,diabetes,hyperlipidemia,unstable angina,smoking and renal dysfunction between the groups(all P＞0.05).And the angiography results showed no difference at the number and location of coronary artery lesions,including prevalence of single-vessel disease [15 cases(24.6％)vs.8 cases (17.0％)],dual-vessel disease [18 cases(29.5％) vs.15 cases(31.9％)] and that of tri-vessel disease [28 cases(45.9 ％) vs.24 cases (51.1 ％)] between partial and complete revascularization groups (all P＞0.05).The follow-up time in two groups were (1235±508)d and (1216±560)d (t=0.24,P＞0.05).All-cause death [ 10 cases ( 16.4 ％) vs.8 cases ( 17.0％)],cardiovascular death [8 cases (13.1％) vs.7 cases(14.9％)],hospitalization with angina [12 cases (19.7％) vs.9 cases (19.1 ％)],with hypertension [7 cases( 11.5 ％)vs.5 cases (10.6 ％)],with cardiac arrhythmia [5cases(8.2％) vs.4 cases(8.5％)],with chronic heart failure [4 cases(6.6％)vs.3 cases(6.4％)],and with all-cause cardiovascular disease [33 cases (54.1％) vs.25 cases(53.2％)] had no significant differences between partial and complete revascularization groups (all P ＞ 0.05).Conclusions Long-term prognosis of partial and complete revascularization is similar in octogenarians with coronary artery disease.

OBJECTIVE:To make clear the antimicrobials used for inpatients in our hospital from September 1999 to March 2000 METHODS:We sampled the records of discharged patients at the ratio of 1/3 of sickbeds in our hospital,and filled in "the questionnaire of antimicrobials used in clinical department" item by item,finally,we carried out comprehensive analysis RESU_LTS:More than half was administration of single and basic antimicrobial Combined use of antimicrobials for severe and mixed infections was rational The rate of using antimicrobials was high(79 64%),especially in preventing perioperative infections,reached nearly 100% The starting-point was high in choice of drug and the newly-developed,special and expensive drugs occupied the front place in order of consumption Combined use of drugs was unduly prevalent Most of treatment depended on experience The rate of bacterial drug resistance test was only performed in 10% of patients CONCLUSION:Rational use of drugs is the main trend,however,the measure directed against existing problem should be worked out

Objective: To examine whether the progression of early diabetic renal disease with normotension can be slowed by ACE inhibitors(ACEI). Methods: MEDLINE and Chinese Biological Medicine Disk were searched for randomized controlled trials about the effect of ACE inhibitors on patients with normotensive early diabetic renal disease from January, 1990 to April, 1999. According to included criteria, 10 studies were chosen at last.Data were combined by RevMan 3.1 software. Results: The pooled effect sizes of urinary microalbuminuria excretion rate, systolic blood pressure, diastolic blood pressure and mean arterial blood pressure were -77.502 mg/24 h[-100.748,-54.256], -5.002 mmHg [-9.630, -0.685 ], -2.949 mmHg[-4.005, -1.892], -4.284 mmHg[-5.444, -3.123] respectively. Regarded progression to clinical albuminuria as end point,the pooled OR(odds ratio) was 0.27[0.18,0.40]. The sub category analysis showed no differences between type 1 and type 2 diabetes.There were no significant correlations between the pooled effect of urinary microalbuminuria excretion rate and systolic blood pressure, diastolic blood pressure or mean arterial blood pressure. Conclusion: ACE inhibitors can decline urinary microalbuminuria excretion rate in patients with normotensive early diabetic renal disease and delay the progression of early diabetic renal disease to clinical albuminuria, and the effects may not depend on its blood pressure reduction effect.

Objective To compare the molluscicidal effects between“Luo-wei”(TDS),a plant molluscicide in 4 percent, and metaldehyde and niclosamide(MNSC)in the field. Methods A natural ecological environment with Oncomelania hupensis was selected as the test area,the test concentrations of TDS and MNSC were 2.5 g/m3 and 2 ml/m3 respectively by the immersion method;the test doses of TDS and MNSC were 3 g/m2 and 2 ml/m2 respectively by the spray method;the doses of WPN in a control group were 2 g/m3 and 2 g/m2 respectively by the two methods above-mentioned. The molluscicidal effects between TDS and MNSC were compared by using the synchronous design method and parallel comparative method. Results In the TDS group,the death rate of snails was 90.70%by immersion for 24 hours,reached to 81.40%after spraying for 7 days,and there were no significant differences among the observation time points in molluscicidal effects(P>0.05). One day after the spraying,the death rate of snails was less in the TDS group compared with that in the MSCN group(P<0.01),but the death rates of snails were similar in both groups 3 days after the spraying(P>0.05). In the MSCN group,the death rate of snails was 99.17%by immersion for 24 hours,reached to 66.07% by spraying for 1 day. In the WPS group,the death rate of snails was 97.15% by immersion for 24 hours,reached to 71.43%after spraying for 1 day,and there were no significant differences(both P>0.05). Conclusion TDS has a good molluscicidal activity and stable efficacy,and the molluscicidal effect of TDS is similar to that of MSCN in the filed, but the molluscicidal sensitivity of TDS is lower than that of MSCN.

Objective To explore the perception and evaluation of patients with somatic symptom disorder about their own diseases and treatment,and to provide theoretical basis for design of illness percep-tion questionnaire for patients with somatic symptoms disorder. Methods A semi-structured interview was conducted among 15 initial and untreated patients with somatic symptom disorder using the descriptive quali-tative study. The data were sorted,encoded,classified,summarized and refined using MAXQDA10 software. Results Three main themes and six sub-themes of illness perception in patients with somatic symptom dis-order were analyzed and sorted out:(1) symptom recognition:including three sub-themes,low understanding of the disease and denial of somatic symptoms as mental illness;(2)drug taking concerns:including two sub-themes worrying about side effects of drugs,drug addiction and having difficulty to stick to the long-term reg-ular medication;(3)emotional reaction:including the obvious negative emotions of depression and helpless-ness sub-theme. Conclusion Patients with somatic symptom disorder have a general bias in illness percep-tion,which has a potential adverse effect on treatment compliance. Therefore,it is necessary for clinical med-ical staff to early estimate patients’illness perception,and carry out mental health education and rational e-motional behavior therapy.

Objective: To analyze the CT manifestations of the 2019 novel coronavirus pneumonia (NCP) combined with severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) literature review, and to summarize the characteristics of CT imaging, so as to improve the ability of rapid and accurate diagnosis. Methods: CT manifestations of two confirmed cases of NCP were reported, meanwhile the literatures on SARS and MERS imaging performance were reviewed and summarized. Results: The two cases of NCP were both in acute stage, the CT imaging showed multiple and scattered ground-glass opacity (GGO) in both lungs, which is similar to the CT performance of SARS and MERS in acute stage. Conclusions The CT features of 2019 novel coronavirus pneumonia are similar to SARS and MERS. It has certain characteristics and changes rapidly with the course of the disease. In the acute stage, GGO and paving stone sign were the main manifestations. In the acute phase, GGO and crazy paving are the main manifestations. In the progress stage, the interlobular septal thickening and consolidation appeared. During the absorption period, the lesions disappeared or fibrosis was left behind, with lung structure distortion and bronchiectasis. Lymphadenopathy and hydrothorax were rare.

Liver is the central hub regulating energy metabolism during feeding-fasting transition. Evidence suggests that fasting and refeeding induce dynamic changes in liver size, but the underlying mechanisms remain unclear. Yes-associated protein (YAP) is a key regulator of organ size. This study aims to explore the role of YAP in fasting- and refeeding-induced changes in liver size. Here, fasting significantly reduced liver size, which was recovered to the normal level after refeeding. Moreover, hepatocyte size was decreased and hepatocyte proliferation was inhibited after fasting. Conversely, refeeding promoted hepatocyte enlargement and proliferation compared to fasted state. Mechanistically, fasting or refeeding regulated the expression of YAP and its downstream targets, as well as the proliferation-related protein cyclin D1 (CCND1). Furthermore, fasting significantly reduced the liver size in AAV-control mice, which was mitigated in AAV Yap (5SA) mice. Yap overexpression also prevented the effect of fasting on hepatocyte size and proliferation. Besides, the recovery of liver size after refeeding was delayed in AAV Yap shRNA mice. Yap knockdown attenuated refeeding-induced hepatocyte enlargement and proliferation. In summary, this study demonstrated that YAP plays an important role in dynamic changes of liver size during fasting-refeeding transition, which provides new evidence for YAP in regulating liver size under energy stress.
