Objective To discuss the application and significance of homocysteine (Hcy),renal function and serum lipid levels in renal transplantation,by testing those from patients after renal transplantation.Methods Hcy,creatinine (Cr),urea nitrogen (BUN),uric acid (UA),total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were detected in transplantation group(n=63) and control group(n=60).Serum Hcy,Cr and BUN of transplantation group were continuously monitored before and 1,3,7,14 days after operation,and the relationship between Hcy and renal function before and after renal transplantation were compared.Results Compared with control group,Hcy,Cr and BUN in transplantation group all increased and the difference between two groups was statistically significant (P<0.05).Hcy,Cr and BUN in transplantation group all decreased after renal transplantation and the differences between two groups had statistical significance (P<0.05).Compared with that before surgery,Hcy,Cr and BUN in transplantation group gradually reduced 1,3,7 and 14 days after surgery,and the differences were statistically significant (P<0.05).Cr and BUN were positively correlated with Hcy (r=0.627,P<0.05).TC and LDL-C in transplantation group were higher than that in control group and the differences had statistical significance (P<0.05) while the difference of TG and HDL-C didn′t have statistical significance (P>0.05).Conclusion Hcy,Cr and BUN can be used as monitoring indicators of efficacy after renal transplantation,also which can be used to observe the incidence and severity of hyperlipidemia.

OBJECTIVE:To systematically evaluate the pharnacoeconomic effect of venlafaxine and escitalopram in the treat-ment of depressive disorders. METHODS:Usingvenlafaxineescitalopramdepressiondepressive episodeantidepressantas key words,retrieved from CNKI,VIP and Wanfang database during base creation date to Dec. 2015,related literatures about venlafaxine and escitalopram in the treatment of depressive disorders were selected. The cure rate of two therapy plans for depres-sive disorders and HAMD score were analyzed statistically by cost-effectiveness analysis of pharnacoeconomics. RESULTS:There was no statistical significance in cure rate and HAMD score between 2 groups(P>0.05),so minimum-cost analysis was adopted. The costs of venlafaxine and escitalopram in the treatment of depressive disorders were 772.03 yuan and 935.77 yuan. CONCLU-SIONS:Therapeutic efficacy of venlafaxine is similar to that of escitalopram in the treatment of depressive disorders,but the for-mer scheme is more economical.

Objective Investigating the CT features and related prognostic factors of high-grade renal clear cell carcinoma.Methods The data of 141 patients with renal clear cell carcinoma treated by radical nephrectomy in our hospital from November 2012 to April 2017 were analyzed retrospectively.There were 102 males and 39 females.Age from 30 to 86 years old.The tumors were located in the left side in 73 cases and 68 in the right.The tumor size ranged from 1.6 cm to 12.7 cm.50 cases of clinical stage T1a,stage T1b 67 cases,24 cases above T2.All patients had CT examination before operation.According to the postoperative pathological nuclear grade,patients were divided into high grade group (Ⅲ-Ⅳ) and low grade group (grade Ⅰ-Ⅱ),clinical data and CT findings were compared between the two groups (tumor size,capsule,CT,with or without leafs,with or without hemorrhagic necrosis),survival situation after the operation.Result The results of CT examination of 141 cases of this study indicated there were 109 cases of complete capsule,85 cases of tumor showed lobulation,102 cases of tumor showed hemorrhagic necrosis,the average CT value is 10-72 HU,35.4 HU in average;enhanced CT value is 32-308 HU,102.1 HU in average.After pathological examination,the nuclear classification was 66 cases in high grade group and 75 cases in low grade group.The CT examination in thc high grade group and the low grade group showed the number of cases with complete capsule [44 cases (33.3％) vs.65 cases (13.3％)] and plain CT scan value [(38.9 ± 1.1) HU) vs.(32.3 ± 1.1) HU],the difference was statistically of significance (P ＜0.01).The high level of patients in group T1 and group above T2 stage were 46 cases and 20 cases.And the cases of low grade group were 71 cases and 4 cases,there was significant difference between two groups (P ＜ 0.01).The 141 cases were followed up for 2-58 months,with an average of 26.4 months.There was statistical significance difference between the two groups of T1 patients and patients above T2 (P ＜ 0.01).The results of CT examination were compared.There were significant differences in the case of intact capsule and the value of CT scan (P ＜ 0.01).The overall survival rate between the two groups was statistically significant (P ＜ 0.05).Conclusions The CT examination of high-grade renal cell carcinoma shows that most of the capsule is not complete and the CT value of the scan is much higher.The pathological grading of renal cell careinoma indicates the malignancy of tumor cells,which is closely related to prognosis.

Objective:To explore the ultrasonography and classification management strategy for adult atrial septal aneurysm (ASA).Methods:Of 138 patients diagnosed with ASA by the transthoracic echocardiography (TTE), in No.83 Army Hospital and No.988 Hospital of Joint Logistic Support Force from January 2015 to October 2019, 103 underwent the transesophageal echocardiography (TEE), and all were examined by the right heart contrast transthoracic echocardiography (cTTE). According to the semi-quantitative method, the shunt was graded, classified, and managed through follow-up or surgical treatment.Results:In the resting state, among 138 patients, 26 cases were detected by TTE as ASA with patent foramen ovale (PFO), showing left-to-right shunt. Among 112 patients with no shunt detected by TTE, 103 cases underwent TEE, of whom 44 cases had PFO and left-to-right shunt. The detection rate of PFO shunt by TEE was significantly higher than that of TTE (42.72% vs 18.84%, P<0.001). Out of the 138 patients who underwent cTTE, 96 cases had different degrees of right-to-left shunt. According to the semi-quantitative standard, there were 15 cases of grade Ⅰ, 28 cases of grade Ⅱ, and 53 cases of grade Ⅲ. The detection rate of cTTE was significantly higher than that of TTE and TEE (69.56% vs 18.84% and 42.72%, both P<0.001). Among these 96 patients with right-to-left shunt detected by cTTE, 52 cases (54.17%) were clinically diagnosed as cryptogenic stroke, with right-to-left shunt in 6 cases of grade Ⅰ, 12 cases of grade Ⅱ, and 34 cases of grade Ⅲ. The number of new infarcts in patients with grade Ⅱ or Ⅲ shunts who received PFO closure via catheter was significantly lower than that of patients who did not receive closure therapy (0 vs 27.27%, P=0.011). Conclusion:ASA combined with PFO and right-to-left shunts were detected more frequently by ultrasonography combined with cTTE in adults, this helps to formulate a reasonable management strategy.

Objective To investigate the molecular mechanism of taurine regulating the polarization of M2 macrophages by mitophagy. Methods THP-1 cells were divided into four groups: M0 group (THP-1 cells were treated by 100 nmol/L phorbol myristate ester for 48 hours to polarize into M0), M2 group (THP-1 cells were induced to polarize into M2 macrophages by 20 ng/mL interferon-4 (IL-4) for 48 hours), M2 combined with taurine groups (added with 40 or 80 mmol/L taurine on the basis of M2 macrophages). The mRNA expression of mannose receptor C type 1(MRC-1), C-C motif chemokine ligand 22(CCL22) and dendritic cell-specific ICAM-3 grabbing non-integrin (CD209) in M2 macrophages were detected by quantitative real-time PCR. Mitochondrial and lysosome probes were used to detect the number of mitochondria and lysosomes by multifunction microplate reader and confocal laser scanning microscope. The level of mitochondrial membrane potential (MMP) was detected by JC-1 MMP assay kit. The expression of mitophagy-related proteins PTEN-induced putative kinase 1 (PINK1) and microtubule-associated protein 1 light chain 3 (LC3) were detected by Western blot analysis. Results Compared with M0 group, the expression of MRC-1, CCL22, CD209 and PINK1, the number of mitochondria and the level of MMP in M2 group were significantly increased, whereas the number of lysosomes and LC3II/LC3I ratio were decreased. Compared with M2 group, the expressions of MRC-1, CCL22 and CD209, the number of mitochondria and the level of MMP in M2 combined with taurine group dropped significantly while the number of lysosomes was found increased, and the protein expression of PINK1 and LC3II/LC3I ratio were also increased. Conclusions The polarization of M2 macrophages is regulated by taurine to prevent excessive polarization via reducing the level of MMP, improving the level of mitophagy, reducing the number of mitochondria, and inhibiting the mRNA expression of polarization markers in M2 macrophages.
