OBJECTIVE To compare mycophenolate mofetil(MMF) with azathioprine(AZA) addition to ciclosporin-prednisone protocol after kidney transplantation in aspect of infections,and to study the etiology of pulmonary infection and urinary tract infection in the two groups.METHODS Totally 249 patients with kidney transplantation were analyzed retrospectively.These patients were divided into two groups according to the immunosuppressive regimen: AZA group(89 patients),and MMF group(160 patients).The various infectious complications were analyzed during a 1-year follow-up,and the etiology of pulmonary infection and urinary tract infection was studied in the two groups.RESULTS The total incidence of the infections,the incidences of the pulmonary infection,urinary tract infecion,wound infection,and so on,during a 1-year follow-up,were equivalent between the two groups.But the incidence of ARDS and the mortality of patients with lung infection was significantly different.The etiology of pulmonary infection was different between the two groups.Cytomegalovirous and fungal infections were higher in MMF group than those in AZA group.Also the etiology of urinary tract infection was different,the incidences of Gram-positive bacterial and fungal infections were higher in MMF group than those in AZA group.CONCLUSIONS Comparing with AZA,MMF increased the opportunity of serious lung infection.The incidences of opportunistic infection and fungal and viral infections increased obviously in MMF group.So therapy should be individualized and aimed.

AIM To investigate if morphine addiction and relapse to morphine-seeking is related to the change in neurosteroid levels in the brain of rats. METHODS Rats were injected ip morphine (5 mg·kg-1·d-1, 18:00-20:00) and trained in conditioned place preference (CPP) box, once daily for 10 d. CPP test was performed 24 h after the last training. After discontinuation of training for 7 d for CPP extinction, then intermittent and inescapable foot-shock (FS, 0.5 mA, 0.5 s on, 40 s off, 15 min) was applied to rats as the priming stimuli for relapse. CPP test was performed 2 h after FS. When CPP test finished, rats were decapitated and the levels of neurosteroids were analyzed using gas chromatography/mass spectrometry. RESULTS CPP was established when rats were injected morphine and trained for 10 d. At the same time, the levels of pregnenolone and allopregnanolone in the brain tissues of rats were significantly increased. When CPP was reinstated in morphine-treated rats by FS-stress after 7 d CPP extinction, the levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate were significantly increased. CONCLUSIONThe development of morphine addiction and relapse may be related to endogenous neurosteroids in rat brain tissues.

Objective: To study the examination of coronary sinus (CS) and blood flow by transthoracic echocardiography(TTE) and transesophageal echocardiography(TEE).Methods: Thirty patients with supraventricular tachycardia were studied by TTE and TEE. The CS was visualized using modified 4 chamber view. The position of the probe was optimized until the coronary sinus with its ostium into the right atrium could be visualized. CS flow recordings were performed by TEE with Doppler sample volume placed in the CS within a distance of no more than 10 mm from its ostium. Results: In all patients the angle between the doppler beam and the long axis of the CS was <30°. The CS was fully displayed in 18 patients by TTE and 28 patients by TEE. The length and width of the CS were (16.53±2.57) mm and (4.51±1.30) mm by TTE, (24.11±2.46) mm and (5.06±0.97) mm by TEE.The CS flow was characterized by biphasic flow.Its flow velocity was (39±7.8), (31±6.1) and (21±4.7) cm/s respectively. The CS flow velocity-imeintegral was(43±11.6),(43±13.0),(27±8.2) cm/s. Conclusion: Echocardiography is reliable for detecting CS and its flow. TTE is more feasible for detecting CS and its flow than TEE.

Recent studies reported that thymoquinone (TQ), a component derived from the medicinal spice Nigella sativa (also called black cumin), exhibited inhibitory effects on cell proliferation of many cancer cell lines. This study was performed to investigate the anti-metastatic effect of thymoquinone on the pancreatic cancer in vitro and in vivo. The results showed that thymoquinone suppressed the migration and invasion of Panc-1 cells in a does-dependent manner. To investigate the possible mechanisms involved in these events, Western blotting analysis was performed, and found that thymoquinone significantly down-regulates NF-kappaB and MMP-9 in Panc-1 cells. In addition, metastatic model simulating human pancreatic cancer was established by orthotropic implantation of histologically intact pancreatic tumor tissue into the pancreatic wall of nude mice. And administration of thymoquinone significantly reduced tumor metastasis compared to untreated control. Furthermore, the expression of NF-kappaB and MMP-9 in tumor tissues was also suppressed after treatment with thymoquinone. Taken together, the results indicate that thymoquinone exerts anti-metastatic activity on pancreatic cancer both in vitro and in vivo, which may be related to down-regulation of NF-kappaB and its regulated molecules such as MMP-9 protein. Consequently, these results provide important insights into thymoquinone as an antimetastatic agent for the treatment of human pancreatic cancer.

AIM: To evaluate the efficacy of phacoemulsification and intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis.
●METHODS:Retrospective study. A total of 57 cases (57 eyes ) with complicated cataract with uveitis were involved in the study from Jan. 2015 to Dec. 2015. All cases underwent phacoemulsification and intraocular lens implantation surgery successfully. The postoperative reaction, effect, complications and so on were retrospectively analyzed after phacoemulsification and intraocular lens implantation surgery. The date of visual outcome was analyzed using Non - parametric Wilcoxon test.
●RESULTS: lris were bleed in 21 eyes ( 37%) , 4 eyes ( 7%) with posterior capsule rapture and posterior chamber intraocular lens was not implanted in 4 eyes ( 7%) . The uncorrected visual acuity ( UCVA ) was significantly increased after surgery. The UCVA of 8 eyes (14%) were 0. 1 or better before surgery, and the UCVA of 42 eyes (74%) were 0. 1 or better 3mo after surgery, the difference was statistically significant ( Z=23. 42, P<0. 001). The corneal edema (17 eyes, 30%), uveitis (2 eyes, 4%) and intraocular hypertension ( 1 eyes, 2%) were appeared in postoperative 1d. The corneal edema (3 eyes, 5%) was appeared in postoperative 1wk. The uveitis ( 1 eyes, 2%) was appeared in postoperative 1mo. The corneal edema (1 eyes, 2%), uveitis (2 eyes, 4%) , intraocular hypertension ( 1 eyes, 2%) and after-cataract ( 3 eyes, 5%) were appeared in postoperative 3mo.
● CONCLUSION: The phacoemulsification combined intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis has good effect and fewer complications.

Objectives By Oxford pathological classification and analysis of circulating complement complement 3 (C3),renal C3 deposition,and clinical laboratory tests,we discussed the correlation between complement C3 and immunoglobin A nephropathy (IgAN) in pathogenesis.Methods A retrospective study of 558 IgAN cases at Xinhua Hospital from January of 2000 through December of 2013 was performed.All 558 IgAN diagnoses were made and confirmed by renal needle biopsy.Results Compared to patients who had circulating C3 ＜ 0.9,patients with circulating C3 level ＞ 0.9 showed statistically significant decreases in serum creatinine [(100.92 ± 105.31) μmol/L vs (157.58 ± 208.39) μmol/L,t =-2.283,P =0.025],blood urea nitrogen [(5.69 ± 2.88) mmol/L vs (7.69 ± 5.90) mmoL/L,t =-2.81,P =0.006];besides,other parameters like IgA,body weight,body mass index (BMI),cholesterol,triglyceride,serum IgA/C3 ratio,albumin,and estimated glomeruli filtrate rate (eGFR) also presented statistically significant differences between two patient groups;no statistically significant differences were observed between two groups in glomerular mesangial cell proliferation,capillary endothelial proliferation,segmental glomerular sclerosis or adhesions,renal tubule atrophy,tubulointerstitial fibrosis,and formation of glomerular crescent;meanwhile,no statistically significant differences were observed between two groups in mesangial depositions of IgA,IgG,IgM,and complement C3;meanwhile the blood level of C3 between C3 deposition negative group,deposition 2 + and 3 + subgroup showed statistically significant differences (2.493 and 2.782;0.013 and 0.006),nevertheless,prognostic indices in Oxford classification,such as mesangial cell proliferation,capillary endothelial proliferation,segmental glomerular sclerosis or adhesions,renal tubule atrophy and tubulointerstitial fibrosis,were also statistically different between two patient groups (Pearson Square test result was 50.782,35.141,21.105,30.182,respectively;P ＜0.01).Conclusions Renal deposition of complement C3 or decrease in circulating C3 level may be associated with a poor prognosis of IgA nephropathy,and alteration in C3 dynamics may be implicated in the pathogenesis of IgAN through its involvement in humoral immunity.

Aim To investigate the effect of CD44 anti-body-A3 D8 on the expression of IL-3 Rα and down-stream PI3K/Akt in NB4 cells. Methods The ex-pression of IL-3 Rα mRNA was detected by real-time quantitative RT-PCR, the IL-3Rα protein expression and changes of PI3 K/Akt signal pathway in NB4 cells treated with A3D8 were analyzed by Western blot. An-nexin-V-FITC/PI double staining flow cytometry was u-tilized to detect the apoptotic cells. The inhibitor of PI3 K/Akt signaling LY294002 combined with A3 D8 was used to inhibit the PI3K/Akt in NB4 cells. Re-sults After treated with A3 D8 , both the transcription-al level and translational level of IL-3 Rα were remark-ably reduced, and the PI3K/Akt pathway was inhibi-ted. LY294002 improved the inhibitory and apoptotic effects of A3D8 on NB4 cells. Conclusion CD44 antibody A3 D8 can downregulate the expression of IL-3Rα and inhibit the downstream PI3K/Akt pathway.
