RESUMO
Objective:To discuss the clinical efficacy of laparoscopic radical cystectomy in the treatment of bladder cancer after partial cystectomy.Methods:The clinical data of 30 patients who underwent laparoscopic radical cystectomy after PC in Sichuan Provincial People's Hospital from March 2016 to August 2020 were retrospectively analyzed. Including 24 males and 6 females with an average age was 62.5 (45.5-82.5)years.6 out of 30 cases underwent pelvic lymph node dissection during PC. All patients had definite pathological diagnosis for the high-grade urothelial carcinoma after PC, and the tumor staging was pT 2-3bN 0M 0.5 patients received postoperative adjuvant chemotherapy with gemcitabine and cisplatin, 6 received postoperative adjuvant radiotherapy, 13 received postoperative adjuvant radiotherapy and chemotherapy, and all patients were received maintenance intravesical instillation. Median time for local tumor recurrence after PC was 9(5-29) months, all patients had pathological diagnosis for the high-grade papillary urothelial carcinoma, cT 2-4N 0M 0 stage.The average tumor diameter was 3.5(2.5-4.5)cm, an average number of tumors was 2(1-3). Laparoscopic salvage cystectomy was performed after recurrence.General anesthesia, supine position, 5 ports were inserted through the abdominal approach. Standard pelvic lymph node dissection (PLND) was used to clean the pelvic lymph nodes. Those who had underwent PLND no longer clean the obturator and peripheral iliac vessels, but including the common iliac vessel and the bifurcation of the abdominal aorta and lymphatic tissues around the inferior vena cava, as well as the presacral lymph nodes. Results:All 30surgeries were successfully performed. The average operative time was 270(240-310)min, average estimated intraoperative blood loss was 180(50-300)ml, and there was no blood transfusion during the perioperative period.The average number of lymph nodes dissected was 18 (10-27). There were 4 cases with positive lymph nodes, of which 3 cases were positive for 2 obturator lymph nodes, and 1 case was positive for 3 obturator and external iliac lymph nodes. No serious intraoperative complications occurred.No lymphatic leakage occurred. The average drainage duration was 4(3-7) d, and postoperative hospital stays was 9(7-20)d. The postoperative pathology was invasive high-grade papillary urothelial carcinoma, and pathological TNM stage was pT 2-4aN 0-2M 0.13 patients received postoperative adjuvant chemotherapy. The average postoperative follow-up time was 23(3-31) months. There were 2 cases of pelvic recurrence and 1 case of retroperitoneal lymph node metastasis. These 3 cases received adjuvant chemotherapy and radiotherapy. Conclusions:Radical cystectomy should be the primary treatment for recurrence of bladder cancer after partial cystectomy.
RESUMO
Objective:To preliminary study the effects of long noncoding Ribonuclei Acid (RNA) small nucleolar RNA host gene 1 (SNHG1) on proliferation of rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS) and the possible mechanism.Methods:The FLS from RA and trauma group were primarily cultured by the explant culture, and the expression of SNHG1 were detected by quantitative polymerase chain reaction (qPCR). Transfection of siRNA was used to interfere the expression of SNHG1. Cell viability was measured using CCK-8 assay and cell cycle distribution was detected by flow cytometry. And the protein level of cyclinD1 was detected by Western blotting. Independent sample t test was used for the comparison between two groups, and the one-way analysis of variance (ANOVA) analysis was used to compare the samples of multiple groups. Results:Compared with FLS from trauma group, SNHG1 expression in RA-FLS was up-regulated [(2.13 ±0.55) vs (1.00 ±0.01)] ( t=-5.87, P=0.004). In RA-FLS, after silencing the expression of SNHG1, the cell viability of SNHG1-siRNA treatment group was down-regulated [(0.930 ±0.033) vs (0.759 ±0.027)]( t=6.879, P=0.002), the proportion of G 2/M+S cells was down-regulated [(28.2 ±1.5)% vs (9.7 ±2.6)%]( t=10.715, P<0.01), and thelevelof cyclinD1 protein was down-regulated ( t=6.168, P=0.004) compared with the negative control group. Conclusion:The SNHG1 is abnormally expressed in RA-FLS, and SNHG1 may participate in the regulation of FLS proliferation by affecting the expression of cyclinD1 protein, thereby contributing to synovial hyperplasia.

RESUMO
Objective To investigate the expression of fibroblast growth factor 4 (FGF4) in serum of active rheumatoid arthritis (RA) and its role in RA synoviocyte proliferation. Methods The serum level of FGF4 were detected by protein arrays in 20 patients with RA, and 20 age and gender matched healthy controls. FLSs were isolated from RA synovium,and were co-cultured with recombinant human FGF4 (rhFGF4). Cell proliferation was quantified by Cell Counting Kit-8 assay and cell cycle distribution was evaluated by flow-cytometry. The protein levels of cyclin D1, phospho-Akt (p-Akt) and phospho-p38 (p-p38) were measured by western blot. Results The serum expression of FGF4 in RA group was higher than that in control group (P=0.041). After being treated with different concentrations of rhFGF4 (12.5, 25, 50, and 100 ng/ml), RA-FLS showed significant increase in cell proliferation, with different rates of [(121 ±8)%], [(126 ±12)%], [(129 ± 12)%], a nd [(134 ±14)%] respectively, comparing with that of the controls [(100 ±0)%, (P12.5=0.049, P25=0.009, P50=0.004, P100=0.001).]. Among them, the percentage of G2/M+S phase cells were [(12.6±3.6)%], [(15.3±4.5)%], [(17.1±5.1)%], [(19.6±4.1)%] respectively, and except the lowest rhFGF4 concentration treatment group of 12.5 ng/ml, G2/M+S phase cells in other groups was significantly increased compared with the controls [(5.4±2.4)%] (P12.5=0.159, P25=0.042, P50=0.018, P100=0.005). And the protein expression of cyclin D1 was up-regulated after being treated with 50 ng/ml and 100 ng/ml rhFGF4 (P50=0.035, P100=0.027). FGF4 transiently increased the expression of p-Akt and p-p38 protein at the concentration of 50 ng/ml. Comparisons of data between groups were performed by independent sample Student's t-test. Statistical significant differences among groups were tested by one-way analysis of variance (ANOVA) or the Kruskal-Wallis test. The Dunnett's t-test was used for multiple comparisons. A P-value of <0.05 was considered statistically significant. Conclusion Our results suggest that FGF4 is highly expressed in the serum of active RA patients. FGF4 may promote the proliferation of RA-FLS via modulating PI3K/Akt and p38-MAPK signaling pathways, which subsequently contributs to synovial hyperplasia.

RESUMO
Objective To further investigate the effect of sinomenine (SIN) on TNF-α-induced VCAM-1 expression in human umbilical vein endothelial cells (HUVECs). Methods HUVECs were isolated from freshly collected umbilical cords. Positive control samples were stimulated with TNF-α, but free of SIN. Negative control samples were treated in the same way, but without TNF-α and SIN. Experimental samples were co-cultured with TNF-α and SIN at various concentrations (0.25, 0.5, and 1.0 mol/L), or TNF-α and dexamethasone (Dex) at concentration of 1.0×10-6 mol/L, or TNF-α with Dex (at concentration of 1.0×10-6mol/L) and SIN at different concentrations (0,25, 0.5, and 1.0 mmol/L) (co-treated groups). VCAM-1 expression was detected by flow cytometry (FCM). Results SIN inhibited expression of VCAM-1 in TNF-α-induced HUVECs, the best effect was shown in the 1.0 mmol/L SIN treated group. VCAM-1 decreased more markedly in the co-treated groups. Conclusion SIN inhibits TNF-α-induced VCAM-1 expression on HUVECs in vitro, and SIN maybe synergistic with Dex in inhibiting TNF-α-induced VCAM-1 expression on HUVECs in vitro.
RESUMO
BACKGROUND: Rheumatoid factor (RF) is a kind of autoantibody which is routinely used as a factor in patients with rheumatoid arthritis (RA) to evaluate disease activity and severity.But in clinical practice, it occurs frequently that RF values do not decrease according to clinical improvement in RA patients. OBJECTIVE: To investigate the association between rheumatoid factor (RF) and activity or disease severity of RA.DESIGN, TIME AND SETTING: A randomized cross-sectional study was performed in the Department of Rheumatology and Immunology, the Third Affiliated Hospital of Sun Yat-sen University during September 2006 and September 2007.PARTICIPANTS: Seventy-six patients,65 females and 11 males,mean age of (44±13) years,with RA diagnosed according to the American College of Rheumatology (ACR) criteria for RA were included in this study. METHODS: Seventy-six patients with active RA were randomly recruited and assessed for functional status,radiographic change,joint pain,morning stiffness, tender joint count (TJC), tender joint score (TJS), swollen joint count (SJC), swollen joint score (SJS), Health Assessment Questionnaire (HAQ), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP),RF,and hemoglobin. The method of Pearson correlation or Spearman rank correlation was performed for assessing the association between RF and these indices separately, normally distributed data for Pearson correlation, nonnormally distributed data for Spearman rank correlation. MAIN OUTCOME MEASURES: Correlation of RF with above mentioned factors. RESULTS: None of the correlation coefficients between RF and indices including age,disease duration, functional status,radiographic change,joint pain, morning stiffness, TJC,TJS,SJC,SJS,HAQ,ESR,CRP,hemoglobin were significant (P>0.05). CONCLUSION: No associations between RF and activity or severity of RA are studied.
RESUMO
[Objective] To investigate the curative effect of the red rice in treating the experimental fractures in the rats.[Methods] 64 Wistar rats suffered with single fracture in the forearm were randomized into two groups,one red rice group and the other normal saline control group.On the twenty-first day and 42 day after operation,the qualitation and morphometric observation of the bone tissue were performed.[Results] After the treatment of the red rice,the bony union of the fractured bone in the rats was obviously accelerated.The morphometric index of the bony tissue was higher than the control group with the statistical significance.The remodeling of the bony callus,the emergence of the lamellar bone and recanalization of the medullary cavity could all be enhanced by the use of the red rice.The mineralized bony callus area,the osteoblast index and the matrical calcification were obviously higher than those of the control group.[Conclusions] The growth of bony callus,the index of the osteoblast,the metrical calcification and the remodeling of the bony callus could all be enhanced by the red rice and therefore the bone union could be accelerated.
