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 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 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.

Background and purpose:Three-dimensional power Doppler angiography (3D-PDA) is a new technique to investigate the vessels in the organs, but the research in thyroid is limited. The purpose of this research was to investigate three-dimensional power Doppler angiography (3D-PDA) in differentiating malignant from benign thyroid nod-ules.Methods:This study prospectively evaluated 103 lesions in 94 patients who were scheduled for surgery. The patients underwent preoperative 3D-PDA scanning. Analysis of the 3D-PDA characteristics includes blood flow pattern, the num-ber of blood vessels, the shape of vessels, the spatial distribution of the vessels, the existence of rich local blood flow within nodules or in the parenchyma surrounding the nodules. This study also analyzed the difference between the benign lesions and the malignant lesions.Results:There were 50 benign lesions and 53 malignant lesions. The sensitivity and specificity of irregular vessels, the asymmetry spatial distribution, rich local blood flow within nodules or in the parenchyma surround-ing the nodules were 64.2%, 96.0%; 56.0%, 88.0%; 54.7%, 96.0%; 60.4% and 94.0%, respectively. The sensitivity, speci-ficity, positive predictive value, negative predictive value and accuracy of 3D-PDA were 83.0%, 94.0%, 93.6%, 83.9% and 90.3%, respectively.Conclusion:3D-PDA provides a useful tool to investigate vascularization of thyroid leisions.This technique is feasible for clinical application and plays an important role in diagnosis of thyroid nodules.
