Objective To explore the effects of oligohydramnios in the late trimester of pregnancy on perinatal infants.Methods Two hundred and sixty-eight pregnant women with oligohydramnios,admitted from June 2000 to June 2007,were involved in present study,and homochronous 300 pregnant women with normal volume of amniotic fluid were enrolled as control group.The clinical data were analyzed to evaluate the influence of oligohydramnios on perinatal infants and on the outcome of delivery.Results The incidences of newborn distress,meconium-contaminated amniotic fluid,apnoea neonatorum,aspiration pneumonia and perinatal infant mortality were obviously higher in the oligohydramnios group than those in control group(P

Objective To study the effects of ShaJi on the indexes of oxygen metabolism such as coronary blood flow in myocardium of anesthetized thoraco-opened dogs. Methods Dogs were randomly divided into control group,4 and 16 mg?kg-1 ShaJi groups,and positive control group(n=6).The anesthetized thoraco-opened dog models were set up.The administration of intravenous injection was used by femoral vein.The blood pressure,heart rate and coronary blood flow(CBF) were measured.Coronary resistance,myocardial oxygen uptake rate,myocardial oxygen consumption index and myocardial oxygen consumption were calculated.Results Compared with control group,the CBF was increased (P0.05).Conclusion ShaJi can significantly ameliorate oxygen metabolism in myocardium of anesthetized thoraco-opened dogs.

Objective To investigate the levels of IL-18,IL-10 and MMP-9 in coronary heart disease(CAD)patients with in-stent restenosis(ISR)after percutaneous coronary intervention (PCI)treatment,so as to discuss the influence of inflammatory fac-tors to ISR after PCI.Methods CAD patients with ISR after PCI were angiographically re-evaluated and formed the ISR group(n=68)and the non-ISR group(n=173)based on the presence or absence of ISR.109 subjects without angiographic evidence of CAD formed a reference control group(control group).The plasma IL-18,IL-10 and MMP-9 concentrations of subjects were measured. Results The concentrations of serum IL-18 and MMP-9 in ISR group and non-ISR group were significantly higher than control group,while IL-10 level was the opposite.Contrasted with non-ISR group,the concentrations of serum IL-18 and MMP-9 in ISR group were significantly higher,but IL-10 level was the opposite too.There were significantly statistical differences(P <0.05)Con-clusion There is significant correlation between ISR and serum levels of IL-18,IL-10 and MMP-9.The inflammation may have im-portant impact on the process of ISR.

Objective To investigate left ventricular systolic function with mitral annulus motion velocity(Sa) with pulsed-wave Doppler tissue imaging(PW-DTI) in patients with coronary arteriosclerosis disease(CAD) after percutaneous coronary intervention(PCI).Methods 52 patients with CAD,who were determined by coronary artery angiography,were divided into two groups,PCI group(n=33) and non-PCI group(n=19).They were followed up with PW-DTI and conventional echocardiography before and 5 d,3 months and 6 months after intervention in PCI ones,before and 6 months after angiography in non-PCI ones.In PCI group,the patients were divided two subgroups: EF≥50% and EF=30%～50%.Results The Sa improved significantly in PCI group 6 months after intervention(P<0.001).EF correlated with Sa(r=0.705,r=0.770 pre-and post-intervention respectively,P<0.0001).Conclusion Sa can be used to evaluate left ventricular systolic function of CAD patients.

BACKGROUND:Fast track surgery, also cal ed enhanced recovery after surgery, is a series of optimal measures adopted during the perioperative period on the basis of evidence-based medicine, to reduce the physical and mental trauma brought to the patient and accelerate their recovery. It has become the research focus of orthopedic clinic as the surgery and anesthesia skil s are improved a lot in recent years, especial y the articular surgery, which has been widely used in clinics. OBJECTIVE:To summarize the clinical study of the application of optimal measures in joint replacement surgery both at home and abroad in recent years. METHODS:The first author searched related articles in PubMed and Chinese Journal Ful-text Database from January 1997 to September 2016. The key words were“joint replacement, enhanced recovery after surgery, multi-mode analgesia, diet management, steroid hormones”. 81 articles were found at last and one monograph was included. RESULTS AND CONCLUSION:(1) We found that the recovery plan reduced the hospital stays of the patients from 4-12 days to 1-3 days, including pre-operative health education, shortening fasting and water-depriving duration before surgery, super-anesthesia before surgery and do not place catheter;adopting general anesthesia and appropriate adductor canal to relieve the pain, and stopping bleeding using tranexamic acid during operation;multi-mode analgesia, faster function exercise after anesthesia recovery, and drinking water in early phase after surgery during the perioperative period of joint replacement surgery conducted by the cooperation of surgeon, anesthetist, nurse and nutritionist. There were no significant improvements of postoperative complications rate and rehospitalization rate. (2) The research found that, enhanced recovery after surgery is suitable for most of the patients receiving joint replacement surgery, including those in advanced age, combined heart and lung disease before surgery, type 2 diabetes and smoking and drinking before surgery.

Objective To investigate the prevalence and risk factors of atherosclerotic renal artery stenosis (ARAS) in patients with ischemic stroke (IS).Methods A total of 596 consecutive patients with ischemic stroke underwent cerebrovascular and renal angiography at our hospital from January 2008 to March 2013.Renal artery stenosis was defined as at least one of renal artery narrowing ≥ 50％ of luminal diameter.Multivariate logistic regression analysis was performed to investigate the association of the clinical variables with ARAS.Results Intracranial arterial stenosis (ICAS) was identified in 203 patients (34.1％),including 108 cases (18.5％) with arteriostenosis ≥ 50％.Extracranial arterial stenosis (ECAS) was identified in 250 patients (41.9％),including 149 cases (25.0％) with arteriostenosis ≥ 50％.The prevalence of ECAS was higher than that of ICAS(x2 =7.86,P ＜ 0.05).ARAS was identified in 77 patients (12.9％),and the prevalence of ARAS in patients with ECAS ≥50％ was higher than that in with ICAS ≥50％ (30.2 ％ vs.18.5％,x2 =4.52,P ＜0.05).Multivariate analysis showed that the age≥ 60 y (OR:2.48,P ＜ 0.05) and ECAS ≥ 50％ (OR:5.37,P ＜ 0.05) were independent risk factors for prevalence of ARAS.Conclusion ARAS is a relatively common finding among patients with ischemic stroke,suggesting that renal angiography should be performed in elderly IS patients,especially for those combined with severe ECAS.

Objective To study the advantages and disadvantages of the application of complete endoscopic and endoscope assisted small incision in thyroid surgery. Methods From September 2010 to September 2013,279 patients with thyroid diseases in our hospital were selected as the research object. Among them,239 cases of thyroid surgery were grouped according to the surgical method,the complete endo-scopic group with 95 cases,endoscope assisted small incision surgery group with 144 cases. The other 40 cases of parathyroid surgery were grouped according to the surgical method,the complete endoscopic group with 5 cases,endoscope assisted small incision group with 35 cases. The results and indicators related to the surgery with the complete endoscopic and endoscope assisted small incision for the thyroid disease and parathyroid gland were compared. Results About thyroid disease,the proportion of women in the complete endoscopic group,the adeno-ma or unilateral gland leaf proportion,thyroid volume,the tumor nodules longest diameter,adenoma or glandular lobe resection time,double leaf full cut or full cutting time and intraoperative blood loss were significantly higher than that of endoscope assisted small incision group,and the age,double leaf time full cut or full cut rate were significantly lower than that of endoscope assisted small incision group,the differences were statistically significant (P<0. 05). About thyroid disease,proportion of chest discomfort,VAS pain score,length of hospital stay and postoperative cosmetic effect of satisfaction scores in complete endoscopic group were significantly higher than that of endoscopy assisted small incision group,the differences were statistically significant (P<0. 05). About parathyroid disease,the age of patients in the complete endo-scopic group was significantly lower than that in endoscopy assisted small incision group,but the operation time and hospital stay were signifi-cantly higher than that of endoscopy assisted small incision group,the differences were statistically significant (P<0. 05). Conclusion The thyroid surgery with complete endoscopic and endoscopy assisted small incision has certain advantages and disadvantages,which should be considered for patients demands,so as to make the best operation program.

Objective To investigate the effects of the low-osmolar nonionic contrast media on renal function in elderly patients suffering from ischemic cerebral vascular disease and undergoing angiography.To study the incidence and risk factors for contrast-induced nephropathy (CIN).Methods 276 elderly patients who were going to receive selective cranial angiography and bilateral renal angiography were included.The 0.9 ％ sodium chloride (1 ml · kg-1 · h-1) was administered in all patients 6 hours before and 12 hours after contrast media administration.No patients suffered from obviously congestive heart failure.The levels of serum creatinine (Scr) and serum urea nitrogen (SUN) were measured 3 days before and at day 1,2,6 after the administration of contrast media respectively.Then creatinine clearance rate (Ccr) was calculated.Multivariate predictors of contrastinduced nephropathy were determined by logistic regression.Results Among the 276 patients,CIN occurred in 19 patients (6.9％),among whom 4 patients suffered from severe renal artery stenosis and received percutaneous transluminal renal angioplasty (PTRA) at 1 week after undergoing angiography.The renal function in the other 15 cases with CIN were recovered to baseline 1evel 3 months after the use of contrast media.No patients underwent a maintenance hemodialysis.In the 19 patients with CIN,the levels of SUN and Scr were higher and Ccr was lower at day 1 and 2 after angiography than before the procedure (all P ＜ 0.05),but the parameters were decreased to preoperative level at day 6 after angiography (all P＞0.05).Logistic regression analysis showed that renal dysfunction,diabetes mellitus and severe renal artery stenosis were the major risk factors for contrast-induced nephropathy.Conclusions Low-osmoiar nonionic contrast used in angiography is safe for elderly patients if adequately hydrated with 0.9 ％ sodium chloride.The clinical risk factors for CIN are renal dysfunction,diabetes mellitus and severe renal artery stenosis.
