Hepatic hemangioma is the most common benign liver tumors in the clinic.Most of hemangioma does not require aggressive treatment,and the indications for resection remain controversial.Different scholars may have different ideas about the surgical treatment of hemangioma.This article will focus on reviewing literatures about indications of hepatic hemangioma.In this paper,we proposed a new standard of surgical indications that named health-related quality of life.

Objective To investigate the relation between serum asymmetric dimethylarginine (ADMA) level and endothelial function before and after living donor kidney transplantation in uremic patients.Methods A total of 38 renal transplant patients (21males and 17 females) and 36 healthy controls (20 males and 16 females) were enrolled. Plasma ADMA, symmetric dimethylarginine (SDMA), malondialdehyde (MDA), glutathione peroxidase (SeGSHPx), C-reactive protein (CRP) were mea-sured before transplantation and on Days 1, 3, 7, 14, and 28 posttransplantation. The brachial artery flow mediated dilatation (FMD) was studied before transplantation and on the 28th day after the transplantation. Results Serum levels of ADMA,SDMA,MDA and CRP were significantly increased, and the activities of nitric oxide (NO) and SeGSHPx were decreased in uremic patients compared with age matched healthy subjects (all P＜0.01). Serum levels of ADMA,SDMA,MDA and CRP decreased while the activities of NO and SeGSHPx increased significantly at the first day after the transplantation (all P＜0.01). The decrement of plasma SDMA normalized on the 28th day (P＞0.05). The FMD was lower in the patients than the control group (P＜0.01) and improved significantly on the 28th day of posttransplantation (P＜0.05). Serum levels of ADMA were positively correlated with MDA (r=0.412, P＜0.01;r=0.342,P＜0.01) and negatively correlated with the values of SeGSHPx (r=-0.345, P＜0.01;r=-0.315, P＜0.01) and FMD (r=-0.452,P＜0.01;r=-0.416,P＜0.01) both before and after kidney transplantation. Conclusion The level of serum ADMA is associated with endothelial function improvement in uremic patients both before and after kidney transplantation.

Objective To explore the risk and treatment of laparoscopic cholecystectomy(LC) in patients with liver cirrhosis and cholelithiasis.Methods To summarize the clinical data of 28 patients with liver cirrhosis and cholelithiasis.The patients were repeated right upper quadrant pain,including 4 cases of gallbladder neck stones incarcerated,gallbladder effusion.Among them,there were 20 cases of hepatitis B cirrhosis,5 cases of schistosomiasis cirrhosis,3 cases of alcohol.Results There were 6 patients with hemorrhage during operation.Among them,5 patients were treated with gelatin sponge,hemostatic gauze and bio-glue spray to stop bleeding,1 case was transferred to open surgery because of bleeding.The remaining 27 cases of LC were successful.Complications occurred in 8 patients,3 cases of increased liver function abnormalities,1 case of upper gastrointestinal bleeding,1 case of mild hepatic encephalopathy,2 cases of significant ascites formation,1 patient underwent subtotal resection of the gallbladder with Hartmanns bag,and bile was found in the ascites after surgery,but the bile disappeared after five days.All patients with complications after symptomatic treatment were cured,no death,no major bleeding and liver failure,bile duct injury,severe biliary fistula and other serious complications.Conclusion Although the risk of LC in patients with liver cirrhosis is higher than that in the general population,with the help of current high-tech surgical instruments,we can safely accomplish this with an improved surgical procedure.As these patients require high technical requirements of surgery,surgeons must have a wealth of experience and familiar laparoscopic liver and gallbladder anatomy.

Objective To explore the curative effect of combination therapy of low-temperature plasma radiofrequency ablation and nasal endoscopy for chronic nasal sinusitis. Methods From January 2010 to January 2012,98 patients with chronic nasal sinusitis in our hospital were ramdomly divided into observation group and control group. The observation group (49 cases) received plasma radiofrequency ablation at low temperature combined nasal endoscopic treatment. The control group (49 cases) were performed only nasal endoscopic treatment. The curative effect of the 2 groups were compared. Results After 1 month and 1 year, the total effective rate of the observation group were 91. 84% and 89. 80%, the total effective rate of the control group were 77. 55% and 73. 47% respectively. To compare the total effective rate of 2 groups were compared,there were statistically significant differences(P<0. 05). Conclusion Curative effect of plasma radiofrequency ablation at low temperature and nasal endoscopy is distinct,it is worthy of being widely applied in clinic.

Objective To observe the high-resolution magnetic resonance imaging (HR-MRI) features of proximal portion of middle cerebral artery (M1 portion) in patients with moyamoya angiopathy (MMA).Methods Forty-six MMA patients and 12 health volunteers,collected in our hospital from January 2014 to September 2015,were chosen in our study;these subjects were performed three dimensional time of flight magnetic resonance angiography (3D-TOF-MRA) and HR-MRI.The quantitative measurements were conducted retrospectively at the minimum cross-sectional area of vessel and maximum thickness of wall;the morphological changes of the vessel wall of the M1 portion and enhancement or not of wall were evaluated.Moreover,general clinical data and vascular risk factors of all patients were evaluated.Results The minimum cross-sectional area of volunteers was (13.71 ± 2.510) mm2,and the maximum thickness was (0.631±0.203) mm;the minimum cross-sectional area of patients with MMA was (2.700±1.511) mm2,remodeling index was (0.209±0.136),and the maximum thickness was (1.078±0.375) mm.Eccentric thickening was noted in 30.4％ patients (14/46),concentric thickening in 69.6％ patients (32/46).Wall non-enhancement was noted in 45.7％ patients (21/46) and wall enhancement in 54.3％ patients (25/46).Eccentric thickening patients had significantly elder age,higher maximum thickness of wall and carotid atherosclerosis rate than concentric thickening patients (P＜0.05).Multivariate Logistic regression showed that carotid atherosclerosis were independently associated with wall eccentric thickening (OR=4.986,95％CI:1.263-36046,P=0.026).Wall enhancement patients had significantly higher maximum thickness of wall and hypertension level than the wall non-enhancement patients (P＜0.05).Logistic regression showed that hypertension was independently associated with wall enhancement (OR=1 1.764,95％CI:2.081-66.51,P=0.005).Hypertension and carotid atherosclerosis were positively related to the wall thickness (r=0.401,P=0.008;r=0.415,P=0.004).Themaximum thickness was significantly higher in hypertension group than that in normal blood pressure group ([1.234±0.4329] mm vs.[0.936±0.2455] mm,P=0.008).Conclusions M1 portion commonly shows concentric thickening,or eccentric thickening when MMA comorbid with atherosclerosis and negative remodeling in MMA patients on HR-MRI.Wall enhancement is associated with wall thickening,and hypertension is an important factor in the wall thickening.

OBJECTIVE: To investigate the relationship between the level of Foxp3 mRNA in the peripheral blood monocytes (PBMCs) with acute rejection or chronic allograft nephropathy after kidney allotransplantation. METHODS: Real-time quantitative polymerase chain reaction was used to examine Foxp3 mRNA expression in the PBMCs from 16 patients with acute rejection, 8 patients with chronic allograft nephropathy, 8 patients at stable stage after kidney transplantation, 8 patients of end-stage renal disease, and 8 normal controls. RESULTS: The level of Foxp3 mRNA in the PBMCs was significantly lower in patients with acute rejection than that in patients with chronic allograft nephropathy (P<0.01). Foxp3 mRNA expression was significantly lower in patients with chronic allograft nephropathy than that in the normal controls, the end-stage renal disease group, and stable stage group (P<0.01). The level of Foxp3 mRNA was not significantly different in the PBMCs among the normal controls, the end-stage renal disease group, and the stable stage group (P>0.05). CONCLUSION The level of Foxp3 mRNA expressed in PBMCs can reflect the status of renal allograft, and may be a noninvasive biomarker for diagnosing acute rejection and chronic allograft nephropathy.

OBJECTIVE: To design short hairpin RNA (shRNA) interference sequence to silence glutathione S-transferase P1 (GSTP1) gene of androgen independent prostate cancer cell line DU145, and to explore its effect on proliferation and sensitivity to chemotherapeutics. METHODS: The target sequence was picked up to form the shRNA, and the 3 shRNA expression vectors were shRNA255, shRNA554 and shRNA593. The DNA template was cloned to plasmid pGPU6/GFP/Neo. The shRNA was identified by enzyme digesting and gene sequencing. The screening experiment was done to pick up the shRNA expression vector with the highest transfection ratio and best gene silencing results. DU145 cells were divided into a blank plasmid group and a shRNA transfected group. According to the chemotherapeutics the DU145 cells were divided into a fluorouracil (FU) group and a paclitaxel (PA) group, and the 2 groups were subdivided into 4 subsets according to the chemotherapeutic concentrations (FU: 30, 60, 120, and 240 μg/mL; PA: 0.2, 2, 10, and 20 μg/mL), meanwhile a blank control group was included respectively. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was used to evaluate the proliferation after the transfection. MTT and terminal de-oxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay were used to detect the inhibition effect of different concentrations of 5-FU or PA on the proliferation and induction of apoptosis of DU145. RESULTS: The transfection ratio of the 3 shRNA expression vectors (shRNA255, shRNA554, and shRNA593) was (63.30±1.04)%, (76.20±0.68)%, and (72.70±0.33)%, and the transfection ratio of shRNA554 was the highest. there was significant difference among the above 3 shRNA expression vectors (P<0.01). After the transfection, the mRNA was 128.31±2.50, 43.24±4.30 and 85.62±6.30, the GSTP1 protein was 163.92±12.40, 65.38±9.30 and 114.25±16.70. After the transfection of shRNA554, the mRNA and protein of GSTP1 were the lowest level. there was significant difference among the above 3 shRNA expression vector (P<0.01). MTT analysis showed that before the transfection, the survival ratio of cells under different concentrations of FU (30, 60, 120, and 240 μg/mL) was (95.60±2.11)%, (90.20±0.86)%, (83.10±3.12)% and (74.60±1.32)%; however after the transfection, the survival ratio of cells was (91.30±1.43)%, (84.60±2.13)%, (73.20±1.52)%, and (65.5±0.942)%. TUNEL assay showed that before the transfection, the apoptosis ratio of cells under different concentrations of FU (30, 60, 120, and 240 μg/mL) was (5.50±0.88)%, (10.20±1.64)%, (15.20±2.39)%, and (25.10±2.59)%; however after the transfection, the apoptosis ratio of cells was (10.8±0.62)%, (15.7±1.32)%, (20.4±1.89)%, and (34.9±2.54)%. After the transfection, the cell survival ratio decreased under the same concentration of FU, and the apoptosis ratio increased, with statistical significance (both P<0.01). MTT analysis showed that before the transfection, the survival ratio of cells under different concentrations of PA (0.2, 2, 10, and 20 μg/mL) was (98.50±2.34)%, (95.20±1.32)%, (89.40±0.68)%, and (82.70±1.73)%; after the transfection the survival ratio of cells was (94.20±0.78)%, (86.50±2.13)%, (78.70±1.34)%, and (70.10±0.76)%. TUNEL assay showed that before the transfection, the apoptosis ratio of cells under different concentrations of PA (0.2, 2, 10, and 20 μg/mL) were (2.40±1.07)%, (5.20±1.33)%, (10.50±2.41)%, (20.70±1.92)%; after the transfection the apoptosis ratio of cells was (5.46±2.13)%, (13.80±1.24)%, (21.20±2.39)%, and (29.20±2.21)%. After the transfection, the cell survival ratio decreased under the same PA concentration, and the apoptosis ratio increased, with statistical significance (both P<0.01). CONCLUSION gene GSTP1 silence via shRNA transfection to androgen independent prostate cancer cell line DU145 can inhibit its proliferation in time dependent manner, and induce apoptosis and raise its sensitivity to chemotherapeutics.

OBJECTIVE: To determine the effect of transient withdrawal of immunosuppressive agents during the treatment of pulmonary infection on long-term survival of patients and graft s. METHODS: A total of 104 patients with post-transplant pulmonary infection were enrolled in this study. These patients received renal transplantation in Center for Organ Transplantation, Xiangya Hospital, Central South University, during December 2005 and August 2014. Among them, 50 patients stopped immunosuppressive agents during the treatment of infection. These patients served as stopping drug (SD) group, whereas the remaining patients who served as a control group did not stop immunosuppressive drugs. The five-year cumulative patient survival, graft survival, and laboratory results were compared between the 2 groups. RESULTS: The five-year cumulative patient survival rates in the SD group were significantly lower than those in the control group [(69.8 ± 7.0)% vs (94.2 ± 3.2)%, P=0.001]. There was no significant difference in the allograft survival rates between the 2 groups [(81.7 ± 6.6)% vs (90.9 ± 4.3)%, P=0.113]. In patients who survived from pulmonary infection, there was no significant difference in long-term survival rates between the 2 groups (P=0.979). CONCLUSION Pulmonary infection impacts allograft survival after patients underwent renal transplantation. Transient stopping immunosuppressive agents during the treatment of infection is a safe and necessary treatment strategy for patients with serious post-transplant pulmonary infection.

Objective: To investigate the correlation between the diversity of biliary bacterial flora and the recurrence of common bile duct stones. Methods: From September 2018 to March 2019, 48 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) at the First Affiliated Hospital of Nanjing Medical University were enrolled and divided into primary choledocholithiasis (primary group, 38 patients) and recurrent choledocholithiasis group (recurrent group, 10 patients). The bile of the patients of the two groups was collected and analyzed with high-throughput sequencing of 16S rRNA. The Chao1 estimator indicated the richness of the biliary bacterial flora, and Shannon index and Simpson index demonstrated the diversity of biliary bacterial flora. The bacterial flora distribution was explored from different levels of phylum, class, order, family, genus and species. Chi-square test and t test were performed for statistical analysis. Results: The Chao1 estimator of the primary group was higher than that of the recurrent group (419.413±118.704 vs. 396.000±70.483), and the difference was statistically significant (t=3.130, P=0.003). At the level of the phylum, the highest abundance of bacteria in the primary group was Firmicute (56.48%), the highest abundance of bacteria in the recurrent group was Proteobacteria (57.79%). The dominant bacteria of the recurrent group was Proteobacteria, which was inconsistent with that of the primary group, and there were significant differences in the distribution of Proteobacteria and Firmicute between two groups (χ²=0.962 and -2.619, both P<0.05). At the genus level, the abundance of Bacillus and Lactococcus of the recurrent group were both lower than those of the primary group (9.75% vs. 20.77%, 10.86% vs. 22.01%, respectively), and the differences were statistically significant (χ²=0.354 and 0.503, both P<0.05). The abundance of Morganella of the recurrent group was higher than that of the primary group (9.00% vs. 0.44%), and the difference was statistically significant (χ²=-2.025, P=0.049). At the species level, the abundance of Bacillus unclassified, Carnobacterium maltaromaticum and Bacillus circulans of the primary group were all higher than those of the recurrent group (17.78% vs. 8.84%, 2.39% vs. 1.11%, 2.59% vs. 0.74%, respectively), and the differences were all statistically significant (χ²=2.540, 2.643 and 2.515, all P<0.05). The abundance of Aeromonas veronii of recurrent group was higher than that of the primary group (2.04% vs. 0.01%), and the difference was statistically significant (χ²=-2.397, P=0.021). The bacteria that had significant effects in the primary group included Lactococcus (P=0.012), Lactobacillus (P=0.033) and Geobacillus (P=0.021), while in the recurrent group, which included Enterobacter (P=0.007), Aeromonadaceae (P=0.001), Actinomycetes (P=0.009), and Aeromonas (P=0.001). Conclusions There are differences in abundance and composition of biliary bacterial flora between the recurrent group and the primary group. It remains to be further studied whether the changes of some bacterial flora correlated with the recurrence of common bile duct stones.
