Objective: To investigate the relationship between serum albumin level and severity of coronary heart disease (CHD). Methods: A total of 237 patients admitted in our hospital from 2008 to 2009 and undergoing coronary angiography were enrolled. CHD severity was evaluated according to clinical types, number of diseased coronary vessels and coronary artery score respectively, and patients were divided into non-CHD group (n=84), angina pectoris group (n=92) and myocardial infarction group (n=61). Serum total protein, albumin and globulin were measured in all patients on second day after admission. Relationship among indexes of CHD severity and serum proteins were analyzed. Results: Compared with non-CHD group, there was significant decrease in albumin level [(40.22±3.56) g/L vs. (39.81±3.56) g/L vs. (38.68±3.43) g/L, P<0.05] in angina pectoris group and myocardial infarction group. Spearman correlation analysis indicated that serum albumin level was significant negatively correlated with clinical types (r=-0.18, P=0.005), number of diseased coronary vessels (r=-0.195, P=0.003) and coronary artery score (r=-0.188, P=0.004). Serum total protein, globulin and ratio of albumin/globulin were not significantly correlated with clinical types, number of diseased coronary vessels and coronary artery score (P>0.05). Conclusion: Serum albumin level is negatively correlated with severity of coronary heart disease. Low serum albumin may be a risk factor for coronary heart disease.

ObjectiveTo investigate the influence on negative emotion of ICU patient's relatives by comprehensive needs intervention.Methods 100 ICU patient's relatives were randomly divided into intervention group and control group,50 cases per group.Patients in intervention group were given comprehensive needs interventions for two weeks,then were tested by self-rating anxiety scale(SAS),self-rating depression scale(SDS) and symptom checklist 90 (SCL-90),and their negative emotion were compared.ResultsExcept for interpersonal relationship factor (P＞ 0.05 ),the other SCL-90 factorial scores of ICU patient's relative were all significantly higher than the national norm before intervention(P ＜ 0.01 ～0.05 ).Anxiety and depression rates in two groups were 64％ and 53％ respectively,SDS standard scores were 49.62 ± 9.18 and 49.70 ± 9.73,SAS scores were 40.08± 11.93 and 40.04 ± 11.76,and they were all significantly higher than normal norm.After intervention,SAS,SDS standard scores and SCL-90 factors of intervention group were significantly decreased,and were superior than control group,and there were statistical difference (P＜ 0.01 ～ 0.05 ).ConclusionThere are so much psychological diseases with the relatives of ICU patients,especially anxiety and depression.

Objeictivie To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) antibody, anti-cyclic citrullinated peptide (anti-CCP) antibodies and glucose-6-phospha-teisomerase (GP1) for rheumatoid arthritis (RA). Methods Anti-MCV antibody, GPI and anti-CCP antibody were detected in serum samples of 109 RA patients, 24 non-RA rheumatic diseases patients and 19 healthy blood donors. The sensitivity and specificity of these parameters for the diagnosis of RA were analyzed. Results Both the positive rate and average cut off concentration of anti-MCV and GPI in RA were higher than those of non-RA rheumatic diseases or healthy controls (P<0.05). A significant difference was found between anti-MCV and GPI in RA patients. The most sensitive and specific parameter in RA was anti-MCV (99.1%) and anti-CCP (90.7%) respectively, but, when anti-MCV combined with anti-CCP, or GPI or anti-CCP and GPI, the specificity could be up to 98.1%. Coniclusions Anti-MCV, anti-CCP and GPI alone or in combination may be valuable parameters for the diagnosis of RA.

Curcumin is the main active component in turmeric, which possesses many pharmacologic effects, including anti-in-flammatory, antioxidant, anti-tumor, anti-atherosclerosis, liver and kidney protection and so on. However, due to its poor bioavail-ability, its clinical application is limited. Therefore, the methods for improving the bioavailability of curcumin were reviewed by refer-ring to a large number of literatures. The bioavailability of curcumin can be improved by different administration routes and various dos-age forms. The review provides theoretical basis and research ideas for the development of new drugs.

Objective To determine the diagnostic value and clinical significance of sonographically detected fetal dysplastic kidney with normal amniotic fluid volume. Methods At the 2nd or 3rd trimester of gestation,the fetuses with unilateral or bilateral renal anomalies (ahnormal size,echo,shape or cyst of the kidney) and normal amniotic fluid volume received systemic ultrasound examination,autopsy or follow-up until after birth. The fetus with only dilated renal pelvis was not included. Results Eleven fetuses of dysplastic renal anomalies with normal amniotic fluid volume were identified by prenatal ultrasound. Among the five fetuses affected by unilateral multicystic kidney dysplasia (MCKD),the renal anomaly was isolated in four fetuses,and the other one was complicated with absence of the ipsilateral hand. One of the two fetuses of unilateral renal agenesis had no other associated anomaly and the other one was complicated with hydrocephalus,spina bifida,ipsilateral absent radius and single umbilical artery,correspongding to the VACTERL syndrome. Two fetuses of pelvic kidney and horseshoe kidney respectively was proved by postnatal ultrasound. One fetus was diagnosed as autosomal dominant polycystic kidney disease(ADPKD)on the basis of multiple renal cysts and a positive family history,the fetus also had cardiac rhabdomyoma. One fetus of bilateral normal sized hyperechoic kidneys was proved to be renal dysplasia by autopsy. Conclusions Unilateral MCKD is the most common type of fetal renal dysplasia which can be detected by prenatal ultrasound with normal amniotic fluid volume. Based on the sonographic characteristics and the family history,most of the dysplastic renal anomalies can be diagnosed prenatally and the prognosis can be predicted.

Objective To observe effects of intranasal sufentanil on analgesia.Methods Eighty-two patients,who scheduled for selective thyroidectomy were randomly divided into the observed group and the control group with 41 cases in each group.In the observed group,patients received intranasal sufentanil 20 μg before the incision about 10 minutes,then administered local infiltration with 0.5% lidocaine.In the control group,patients received water for injection which was placebo instead sufentanil.By double blind method observed verbal mting scale(VRS)score.The values of NBP,HR,SpO2 and respiration rate(RR)were recorded before intranasal drugs and 5,10,20,40,60 min after intranasal drugs.The amount of local anesthetic,the size of thyroid gland,the time of operation and the satisfaction were compared between the two groups.Nausea vomiting and pruritus were also observed in order to assess the safety of intranasal sufentanil.Results All patients completed the operation successfully.The RR in the observed group decreased to(13.1±0.5),(13.8±0.6),(13.8±0.8)times/min after intranasal sufentanil 10,20,40 min,and had significant difference with those before intranasal drugs(P＜0.05),anastated after 60 min.VRS score of the observed group was(2.0±0.4)scales,less than the control group,and had significant difference when the surgeon was dissecting thyroid gland(P＜0.05).The amount of local anesthetic in the observed group was(42.5±6.9)ml,less than the control group(63.7±4.3)ml(P＜0.05).The satisfaction had significant difference between the two groups(P＜0.05).Conclusion Intranasal sufentanil for analgesia is a safe and useful technology.

Objective To evaluate the ultrasonographic (US) features and evolution of breast fat necrosis after cosmetic augmentation with autologous fat obtained by liposuction, to help distinguish fat necrosis from more ominous breast masses. Methods Breast sonography was performed on 38 patients underwent bilateral breast augmentation by autologous fat injection to evaluate the grafted fat tissues in interval of 3-6 month after the operation. Observations in follow up sonography included the sizes,positions, shape,echogenicity,margin features, calcifications and evolutions of the suspicious nodules in the breasts. Results Seventy-six nodules occurred in 25 of the 38 patients were detected after the fat graft. Among the 76 nodules,52 were cystic(68. 4%) ,8 were complex(10. 5%) and 16 were solid(21.1%). The analysis of the predominant features of the nodules sonographic appearances were as follows: all the nodules had no flow signal, 66 (86. 8%) had clear margins,54(71. 1%) had regular shapes,52 were cystic(68. 4%) ,63(82. 9% ) had no calcifications, 10(13. 2%) had egg-like calcifications,74(97. 4% ) had no halo,and the positions of the solid components in 8 complex nodules move following the change of the detected body position. There were 7 nodules with fat necrosis removed surgically and confirmed by pathology. Conclusions Breast ultrasound is an accurate and simple method to follow up the temporal changes of the fat nodules after autologous fat injection. It may help to avoid unnecessary biopsies.

Objective To evaluate the contrast enhanced perfusion pattern of PTC micro-vascular imaging (MVI) quantitatively.Investigate the correlation between PTC MVI features and CD34 micro-vascular density (MVD).Methods Thirty-nine pathological and clinical confirmed sporadic PTCs were evaluated with real-time gray-scale contrast-ernhanced micro-vascular imaging under a low mechanical index.The micro-bubble agent was SoneVue.Of the 39 PTCs,33 were classical PTCs,6 were PTC with follicular variant (FVPTC).The △ ROI,which is the subtraction of peak echo intensity between the lesion region of interest (ROI) and normal thyroid parenchyma ROI,was used to evaluate the perfusion characteristics of PTC MVI quantitatively.The paraffined specimens were selected for immunohistochemical (IHC) staining for CD3,and the correlation between △ ROI and the CD34 were evaluated.Results △ ROI was strongly correlated with the CD34 expression (P=0.000),significant differences were detected in the distribution pattern of △ ROI value among different CD34 expression levels,no overlapping of the mean △ ROI values and the 95％ confidence intervals was found among the 3 CD34 expression levels.The PTC MVI perfusion was classified into 3 patterns,low perfusion,focal perfiusion and high perfusion,on the basis of combining△ ROI values with the peak ehco pattem in time-intensity curve.Conclusions The △ ROI is strongly correlated with the CD34 expression in papillary thyroid cancer.It can be used for the quantitative evaluation ofPTC MVI pattem and intensity as an objective indicator.
