1.The correlation research between serum lactadherin,sialic acid level and patients with coronary heart disease
International Journal of Laboratory Medicine 2017;38(13):1793-1795
Objective To study the relationship between serum lactadherin (MFG-E8),sialic acid (SA) level and coronary heart disease (CHD) occurrence and development.Methods 166 patients in our hospital were selected from June 2014 to November 2015,and then according to the result of coronary angiography divide the subjects into control group (n=56,the result of coronary angiography completely normal) and CHD group,including stable angina 48 cases (StA subgroup),unstable angina 30 cases (UA subgroup) and acute myocardial infarction 32 cases (AMI subgroup).The serum level of MFG-E8 was detected by ELISA method,the serum level of SA,hs-CRP and lipid index were detected by biochemical analysis.Gensini score showed the severity of coronary stenosis.The correlation analysis between detecting parameters was carried out by Spearman method.Results Compared with the control group,the patients with CHD have a higher level of serum SA and a lower level of MFG-E8 (both P<0.05).The AMI subgroup has a lower level of serum MFG-E8 than StA and UA subgroups,and the AMI subgroup has a higher level of serum SA than StA and UA subgroups (all P<0.05).The correlation analysis showed that the serum SA has a positively correlation with the level of TG,hs-CRP,and Gensini score,and has a negatively correlated with the level of MFG-E8 (all P<0.05).The MFG-E8 has a negatively correlated with the level of TG,hs-CRP,and Gensini score (all P<0.05).Conclusion MFG-E8 and SA play an important role in the development of CHD,and combined detection of serum MFG-E8 and SA may be helpful in the clinical diagnosis and risk assessment of patients with CHD.

China Journal of Endoscopy 2016;22(2):87-90
Objective To evaluate the safety and effect of extraperitoneal laparoscopic radical prostatectomy for high-risk prostate cancer. Methods From January 2012 to August 2015, 49 patients diagnosed high-risk prostate cancer underwent extraperitoneal laparoscopic radical prostatectomy with 'sandwich' urethra reconstruction. Results None converted to open surgery and the mean operative time was (2.15 ±0.29) h, mean intraoperative blood loss was (60.25 ± 20.29) ml. No rectal injury was observed. The patients were ambulant 1 to 2 days postoperatively. Pelvic lymph nodes metastasis was found in 5 cases. Positive margin was found in 13 cases. Mild urinary incontinence oc-curred in 3 cases. Urethral stenosis occurred in 2 cases. Biochemical relapses occurred on 5 cases during the follow-ing period of 1~43 months for 46 cases. Conclusions Extraperitoneal laparoscopic radical prostatectomy is safe and effective in treatment of high-risk prostate cancer. The very key is to master the anatomy of prostate and laparoscop-ic techniques.

Integrating visualization toolkit and the capability of interaction, bidirectional communication and graphics rendering which provided by HTML5, we explored and experimented on the feasibility of remote medical image reconstruction and interaction in pure Web. We prompted server-centric method which did not need to download the big medical data to local connections and avoided considering network transmission pressure and the three-dimensional (3D) rendering capability of client hardware. The method integrated remote medical image reconstruction and interaction into Web seamlessly, which was applicable to lower-end computers and mobile devices. Finally, we tested this method in the Internet and achieved real-time effects. This Web-based 3D reconstruction and interaction method, which crosses over internet terminals and performance limited devices, may be useful for remote medical assistant.

Tumor 2015;35(6):639-645
Objective: To investigate the expression of A20, also known as tumor necrosis factor alpha-induced protein 3 (TNFAIP3) in hepatocellular carcinoma (HCC), and to explore its relationship with prognosis. Methods: The expression levels of A20 mRNA in 86 cases of HCC and the corresponding adjacent tissues as well as 26 cases of normal liver tissues from the patients with hepatic hemangioma were measured by real-time fluorescent quantitative-PCR. The correlations of A20 expression with clinicopathologic features and prognosis of HCC patients after radical operation were analyzed. Results: The relative expression level of A20 mRNA in HCC tissues was 1.620+0.155, which was significantly higher than that in normal liver tissues (0.410±0.043, P < 0.001). The relative expression level in A20 mRNA in para-HCC tissues was 1.215±0.134, which was significantly higher than that in normal liver tissues (P = 0.001). There was no significant difference in A20 mRNA expression level between HCC and para-HCC tissues (P = 0.087). The expression level of A20 in HCC tissues was closely correlated with tumor differentiation (P < 0.001). Kaplan-Meier analysis showed that HCC patients with high expression of A20 mRNA had poorer prognosis with lower probability of overall survival (OS, P = 0.016) and shorter time to tumor recurrence (TTR, P = 0.011). The univariate analysis showed that the expression level of A20 mRNA was closely related to the prognosis of HCC patients (OS: P = 0.012; TTR: P = 0.013). The multivariate analysis showed that A20 could be an independent prognostic factor for HCC patients (OS: P = 0.021; TTR: P = 0.018). Conclusion: The expression level of A20 mRNA in HCC is significantly higher than that in normal liver. A20 may be used as an independent prognostic indicator for survival and recurrence of HCC patients.

Objective:To explore the effects of linagliptin on blood glucose, islet function and liver stiffness measurement (LSM) in patients with non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM).Methods:During the period from January 2019 to April 2020, 102 patients with NAFLD and T2DM in the Second Affiliated Hospital of Suzhou University were enrolled and divided into study group and control group according to different treatment methods, with 51 cases in each group. The control group was treated with metformin, while study group was treated with linagliptin and metformin. The clinical curative effect on fatty liver was observed and compared between the two groups. The levels of fasting blood glucose (FBG), glycated hemoglobin (HbA 1c), homeostasis model assessment of insulin resistance (HOMA-IR), homeostasis model assessment of islet insulin cell function index β (HOMA-β), alanine aminotransferase (ALT), serum aspartate aminotransferase (AST), glutamyl transpeptidase (GGT) and LSM before and after treatment were compared between the two groups. The occurrence of adverse reactions during treatment in both groups was recorded. Results:The total response rate of fatty liver treatment in study group was significantly higher than that in control group: 96.1% (49/51) vs. 82.4% (42/51), and there was statistical difference ( P<0.05). After treatment, levels of FBG, HbA 1c, HOMA-IR, serum ALT, AST, GGT and LSM in study group were significantly lower than those in control group: (7.1 ± 1.0) mmol/L vs. (7.9 ± 0.9) mmol/L, (7.5 ± 0.7)% vs. (7.9 ± 1.0)%, 3.2 ± 0.2 vs. 4.7 ± 0.3, (56.7 ± 10.4) U/L vs. (62.8 ± 8.2) U/L, (73.2 ± 6.8) U/L vs. (81.1 ± 6.7) U/L, (56.4 ± 10.2) U/L vs. (62.3 ± 8.1) U/L, (10.5 ± 3.3) kPa vs. (13.4 ± 1.6), the level of HOMA-β was significantly higher than that in control group: 48.5 ± 8.3 vs. 41.2 ± 7.1, and there were statistical differences ( P<0.05). The incidence of adverse reactions during treatment was low in both groups, and the difference was not statistically significant between the two groups ( P>0.05). Conclusions:Linagliptin can improve clinical curative effect on fatty liver in patients with NAFLD and T2DM, control blood glucose level, and improve islet function, liver function and liver fibrosis, with higher medication safety.

A total of 1512 adult inhabitants were randomly recruited in Zhaiji district of Guiyang city in September2009.The levels of triglyceride (TG),systolic blood pressure,diastolic blood pressure,and the prevalences of abdominal obesity and hypertension increased significantly in the subclinical hypothyroidism group conpared to the euthyroid group (P<0.05).The prevalences of high TG,low high density lipoprotein-cholesterol,and metabolic syndrome (MS) in the subgroup Ⅳ were higher than the subgroup Ⅰ (P<0.05).Correlation analysis revealed that TSH was positively related to TG (P<0.05).Logistic regression demonstrated that TSH was a risk factor for MS.Either in the euthyroid or total subjects serum TSH levels in the MS group were significantly higher than those in non-MS group(P<0.05).
