Objective To investigate the ultrasonographic characteristics of angiofollicular lymph node hyperplasia (AFH). Methods The ultrasonographic and pathological characteristics in nine patients with pathologically confirmed AFH were retrospectively analyzed. Results All the 9 patients were hyaline vascular type of AFH. Ultrasonic manifestations included complete capsule, regular shape and clear boundary, internal solide low echo, mild posterior echo enhancement and without cystic degeneration, which was relative to the less incidence of necrosis and hemorrhage on pathologic findings. Calcification in the lesions were found in two patients. Color Doppler flow signals were observed in the periphery of lesions in 9 patients, and rich flow signals were observed in the center of lesions in 2 of them. Conclusion The ultrasonic manifestations of AFH has its own characteristics. The ultrasonic manifestations combined with clinical features are helpful to the differential diagnosis. The final diagnosis depends on pathologic examination.

Objective To investigate the effects of neurolytic celiac plexus block(NCPB) on stress response during the early stage of partial hepatectomy(PH) postoperation in rats.Methods Thirty healthy SPF-grade male Sprague-Dawley rats were randomly divided into control group and NCPB group,and then were constructed the 70％ PH model.NCPB group received NCPB with 0.5 ％ lidocaine before closing abdominal,and control group received the same procedures,but 0.9％ physiological saline was injected instead of 0.5 ％ lidocaine.The serum concentration of CRP,GC,ACTH,NA and AD,and the levels of serum TNF-α and IL-1β were determined at 6 hours,12 hours and 24 hours after PH.The western blot assay was performed to examine the expression of GR in the peripheral blood mononuclear cells (PBMCs).Results The obvious stress response was produced within 24 hours after PH in rats,postoperative serum CRP,GC,ACTH,NA and AD concentrations increased in the different extent,but the NCPB group were significantly lower than those in the control group in the corresponding time point (P ＜0.01 or P ＜0.05).The expression levels of GR in PBMCs in the control group were significantly decreased after PH,and markedly lower than those in the NCPB group in the corresponding time point(P ＜ 0.01).The serum TNF-o and IL-1β levels were gradually increased in the control group and NCPB group within 24 hours after PH.But at the respective time points,the levels in the NCPB group were significantly lower than those in control group(P ＜ 0.01 or P ＜ 0.05).Conclusion Intraoperation NCPB can effectively inhibit postoperative stress response at the early stage after PH,and thereby help to reduce the degree of systemic inflammatory response.

Objective To evaluate the significance of homocysteine(HCY)and color Doppler flow imaging(CDFI)in the diagnosis and treatment of the renal damage in hypertension.Methods Seventy-two patients were divided into 3 groups according to the indicators of renal damage of hypertension.HCY in blood and the parameters of three grades renal artery with CDFI were measured and compared with 20 controls.Besides these，the relationship between HCY and resistant index(RI)of interlobar renal artery (IRA)was also analysed.Results①The level of HCY in hypertension was much more higher than the level in controls.HCY increased with the damage of renal function，and there were significant differences between different groups(P＜0.05).②The Vmax and Vmin were slower gradually，but PI and RI were higher with the severity of the renal damage(P＜0.01).③HCY were positive correlation with IRNs RI(r=0，35，P＜0.0 1).Conclusions The changes of CDFI can reflect the conditions of renal blood flow，it is possible to know renal blood flow by measuring RI of IRA.The level of HCY will increase gradually with the degression of renal function，it iS useful to evaluate the renal damage.The measurement of CDFI for hypertensive patients is valuable not only for the evaluations of their renal function but also for the severity of hyperhomocysteinemal and their therapy condition.

OBJECTIVE:To construct the structure equation model for the burden of chronic disease inpatients in primary hos-pital before and after the implementation of zero price policy,and analyze the changes of burden factor loading. METHODS:6 pri-mary hospitals were randomly selected in Danyang,Jiangsu province. The data of hospitalization expenses for chronic diseases(hy-pertension,diabetes,bronchitis)were collected before and after the implementation of zero price policy. Using drug cost,nursing fees,inspection fees and treatment fees as independent variables,hospitalization burden as latent variable,SPSS and AMOS 24.0 software were adopted to establish the model. RESULTS:The burden factor loading of inpatients changed greatly before and after the implementation of zero price policy. χ2=24.586,χ2/df=1.446, RMSEA=0.019,GFI=0.995,AGFI=0.989,CFI=0.988,NFI=0.963 manifested good model fitting. Factor loading of drug cost increased greatly,indicating the burden of inpatients was reduced after the implementation of zero price policy. Factor loading of inspection fees and treatment fees increased significantly,the charac-terization effects of them to the burden of inpatients were enhanced. Factor loading of nursing fees was the lowest,and it had the weakest effects on the burden of inpatients,of which the government should enhance the regulation. CONCLUSIONS:Established model has good reliability and validity. It can reflect the change of burden factor loading of inpatients before and after the implemen-tation of zero price policy.

The patients with diabetic retinopathy (DR) had higher plasma level of soluble E-selectin than those without DR, and the level of soluble E-selectin showed a positive relationship with the extent of DR, suggesting that E-selectin might play a role in the development of DR.

Objective To detect mRNA expressions of STING and type Ⅰ interferons(IFN-α and IFN-β) in peripheral blood mononuclear ceils (PBMCs) of patients with chronic hepatitis C(CHC).Methods 113 patients with CHC and 94 healthy controls were collected from Renmin Hospital of Wuhan University during January 2015 and January 2016.Expressions of mRNA of STING,RIG-1,IFN-α and IFN-β were detected by real-time quantitative PCR,and their relative expression values were obtained by 2-△△Ct method and the results were statistically analyzed.Results The expression of mRNA of STING,RIG-1,IFN-α and IFN-β in CHC were 0.018,0.361,0.578 and 0.573 times than its in healthy controls respectively and the differences were statistically significant (t-8.28,4.26,2.18 and 2.07,all P ＜ 0.05).Pearson correlation analysis showed that mRNA expressions of STING in healthy controls were positively correlated with that of IFN-α mRNA and IFN-β mRNA (r=0.487 and 0.207,all P＜0.05),which had no correlation in CHC (r=0.174 and 0.091,all P＞0.05).The expressions of STING mRNA was positively correlated with that of RIG-1 mRNA in healthycontrols (r=0.222,P＜0.05),but there was no correlation of expression in CHC between STING mRNA and RIG-1 mRNA (r=-0.029,P＞0.05).Conclusion Compared with healthy controls,the expression of STING,RIG-1,IFN-α and IFN-β mRNA were all reduced.There was positive correlation between STING and RIG-1,IFN-α and IFN-β in healthy controls,but no correlation in CHC.

Objective To explore the relation of stroke and metabolic syndrome (MS), and provide theoretical evidence for prevention of stroke and MS. Methods Five hundred stroke patients accompanied with MS were enrolled, and divided into different types according to the distribution of the components of metabolic syndrome and abnormal metabolic condition. The systolic blood pressure(SBP) ,diastolic blood pressure( DBP),fasting glycemia ( FPG ), triglycerides ( TG ), total cholesterol ( TC ), low density density lipoprotern-cholesterol (LDL-C), high density density lipoprotern-cholesterol (HDL-C)of each patient were detected and recorded. Results Among these stroke patients with MS, most patients were 60 - 69 years old ( 39.60% ), and there was no significant difference between two gender( P = 0. 545 ). Among each component of MS, hypertension was most related to MS;patients complicated with hypertension + hyperlipidemia + hyperglycemia were the most major proportion of stroke patients with MS(48. 00% ). Conclusion MS and its components are all risk factors for stroke,and the more complication the patients had,the more patients suffered from stroke with MS. Targeted interventions of different type of abnormal condition has important prevention effect on MS and stroke.

Objective To investigate the influencing factors of strain ratio(SR) value in differential diagnosis of benign and malignant thyroid nodules by using real-time tissue elastosonography (RTE).Methods One hundred and seventy-one patients with a total of 171 thyroid nodules were analyzed retrospectively.Their images,including 2D ultrasound,color Doppler flow imaging (CDFI) and RTE were reviewed and conventional ultrasonic features (including the maximum diameter,composition,shape,magin,calcification,intranodular blood flow,depth) and SR value were recorded.Receiver-operating characteristic (ROC) curve was employed to assess the diagnostic efficiency of SR value in differentiating malignant nodules from benign ones.Firstly,the correlation between the aforementioned factors and SR value was assessed by using malignant lesions as the research subjects.And then,the multiple linear regressions (MLR) was employed to evaluate the influence of particular features which turned out to be an important disturbing factor affecting SR value of the lesion in the first step of analysis and pathological type in all nodules (benign and malignant) on SR value.Results With a cut-off point of SR value 3.67,the sensitivity and specificity of SR value in differential diagnosis of benign and malignant thyroid nodules was 85.6％ and 81.1 ％,respectively,and the area under ROC curve was 0.891.Correlation between the maximum diameter and calcification and SR value was significant(r =0.345 and 0.261 respectively,P ＜0.05).However,there was no significant correlation between other features(5 factors) and SR value(P ≥0.05).MLR indicated that the maximum diameter,calcification and the type of pathology of the nodule were associated with SR value (P ＜ 0.05).Among them,pathological nature was the most significant impact factor with a standardized coefficient 0.494).Conclusions SR value can be used to evaluate the hardness of thyroid nodules semi-quantitatively.Its value mainly depends on the pathological nature of the nodules.The maximum diameter and calcification are also the influencing factors of SR value.However,the composition,shape,margin,intranodular blood flow and depth have no obvious effect on SR value.

Objective Neutrophil/lymphocyte ratio (NLR) is an easy-to-analyze inflammation biomarker but few studies have assessed the relationship between NLR and type 2 diabetes. In order to evaluate how NLR is related to type 2 diabetes, we designed a large scale cross?sectional study in an adult population. Method A cross?sectional study (including 49 861 men and 40 376 women) was conducted on participants recruited from the Health Management Center of Tianjin Medical University General Hospital in Tianjin, China. Measurements of neutrophil and lymphocyte counts, fasting blood glucose and other potential confounding factors were performed. Type 2 diabetes was defined according to the criteria of American Diabetes Association. Adjusted logistic regression models were used to assess relationships between NLR quintiles and type 2 diabetes. Result In the final multivariate models, the odds ratios (95% confidence interval) for T2D across NLR quintiles were 1.00 (Reference), 1.19 (1.05, 1.35), 1.33 (1.17, 1.50), 1.28 (1.13, 1.44) and 1.34 (1.19, 1.51) (P for trend<0.000 1), in men. Similar relationships were also observed in women. Conclusion This study demonstrated that NLR was related to the prevalence of type 2 diabetes in men and women, and suggesting that NLR may be an efficient and accurate prognostic biomarker for type 2 diabetes.
