OBJECTIVE: To compared the therapeutic effect between filiform fire needle assisted 308 nm excimer laser and simple 308 nm excimer laser on vitiligo of different parts. METHODS: Target lesions of 134 patients were divided into an observation group and a control group according to the principle of self-controlled, 201 pieces in each one. In the observation group, filiform fire needle was performed at target lesions. Then target lesions both of the two groups were irradiated with 308 nm excimer laser at the same time. Once every 2 weeks, totally 10 treatments were required. The effective rate and effective rate, color recovery rate and responding time of different parts in the two groups were evaluated 2 weeks after treatment. RESULTS: The effective rate in the observation group was 82.59% (166/201), which was higher than 68.16% (137/201) in the control group (<0.01). The effective rate of face-neck, trunk, limbs and hand-foot were 90.32%, 81.63%, 81.48% and 58.62% respectively in the observation group, which were higher than 82.80%, 69.39%, 51.85% and 31.03% in the control group (<0.01, <0.05). The color recovery rate of different parts in the observation group was higher than the control group, and the effect was faster in the observation group (<0.01, <0.05). CONCLUSION Filiform fire needle as an adjunctive therapy, combined with 308 nm excimer laser are more effective than simple 308 nm excimer laser for vitiligo of different parts. Combination therapy has a shorter responding time, the face-neck has the best effect and hand-foot has poor effect.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

OBJECTIVE: To explore the correlation of EB virus infection with the prognosis of B-ALL children. METHODS: The peripheral blood of children with newly diagnosed B-ALL admitted in Children's Hospital of Chongqing Medical University from January 2012 to December 2017 were collected, and the EBV DNA in plasma was detected by real-time quantitative PCR. The clinical data of B-ALL children were collected and the correlation of EBV infection with the prognosis of B-ALL children was analyzed. RESULTS: Among 162 B-ALL children, the EBV infection rate was 41.36%. Univariate analysis showed that the B-ALL children with EBV infection had the poor prognosis and higher risk of shorter survival time, as compared with B-ALL children without EBV infection (HR=2.373, 95% CI: 1.129-4.987) (P＜0.05), the multivariate analysis showed that the result was consistent with result of univariate analysis indicating that EBV infection was an independent predictor for poor prognosis of B-ALL children. CONCLUSION The EBV infection may play an important role in the occurrence and progression of B-ALL and is an independent predictor for poor prognosis, therefore the detection of EBV DNA in plasma of B-ALL children possesses an important significance for evaluation of B-ALL children's prognosis.

OBJECTIVE: To investigate the relationship between maternal peripheral blood mononuclear cells (PBMC) hepatitis B virus (HBV) covalenty closed circular deoxyribonucleic acid (cccDNA) and other HBV serological markers and its effects on HBV intrauterine transmission. METHODS: We enrolled 290 newborns and their hepatitis B surface antigen (HBsAg) positive mothers. HBV cccDNA in PBMC and HBV DNA in serum were detected by a real-time PCR-TaqMan probe while HBV serological markers were detected with an electrochemiluminescence immunoassay. RESULTS: There was a positive correlation between the levels of PBMC HBV cccDNA and serum HBV DNA and HBeAg (r = 0.436 and 0.403, P < 0.001). The detection rate of pattern A ['HBsAg (+), HBeAg (+), and anti-HBc (+)'] was significantly higher in the PBMC HBV cccDNA positive group than in the control group (χ2 = 48.48, P < 0.001). There was a significant association between HBV intrauterine transmission and PBMC HBV cccDNA (χ2 = 9.28, P = 0.002). In the presence of serum HBV DNA, HBeAg, and PBMC HBV cccDNA, the risk of HBV intrauterine transmission was three times higher (OR = 3.69, 95% CI: 1.30-10.42) than that observed in their absence. The risk of HBV intrauterine transmission was the greatest (OR = 5.89, 95% CI: 2.35-14.72) when both PBMC HBV cccDNA and pattern A were present. A Bayesian network model showed that maternal PBMC HBV cccDNA was directly related to HBV intrauterine transmission. CONCLUSION PBMC HBV cccDNA may be a direct risk factor for HBV intrauterine transmission. Our study suggests that serological markers could be combined with PBMC-related markers in prenatal testing.

The aim of this paper was to systematically evaluate the toxicity-reducing effect of Tripterygium-licorice in animal experiments,and also to provide evidence for basic research on the toxicity reduction of Tripterygium wilfordii. The PubMed,EMbase,Web of Science,CBM,CNKI and Wan Fang Databases from their establishment to August 31 th,2018 were searched. Two independent reviewers screened the papers,extracted the data,assessed the risk of bias using SYRCLE assessment tool and conducted Meta-analysis with Rev Man 5. 3 software. A total of 10 papers involving 31 studies were finally included,15 studies of which were used for Meta-analysis. Four studies were included for chronic hepatotoxicity animal model. In experimental group( 34 animals),Tripterygium was administered at dose of 0. 09-0. 1 mg·kg-1·d-1,and glycyrrhizic acid was administered at dose of 90-100 mg·kg-1,both for 2 weeks; in control group( 34 animals),glycyrrhizic acid was replaced with equal volume of normal saline. Eleven studies were included for acute hepatotoxicity animal model. In experimental group( 66 animals),glycyrrhizic acid was administered at dose of 75-480 mg·kg-1 for 7 days,then glycyrrhizic acid was stopped,and Tripterygium began to be administered at dose of 0. 6-1. 0 mg·kg-1 per 24 h or 48 h for a total of 1-2 times; in control group( 66 animals),glycyrrhizic acid was replaced with equal volume of normal saline or corresponding solvent. The results of Meta-analysis showed that in both chronic hepatotoxicity animal model and acute hepatotoxicity animal model,the transaminase levels in the experimental group were lower than those in the control group( P < 0. 05). Subgroup analysis of acute hepatotoxicity animal model showed that the transaminase levels in the experimental group were lower than those in the control group for every subgroup except " glycyrrhizic acid 75 mg·kg-1" subgroup. However,in terms of the mean difference( MD) and confidence interval( CI),there was no significant difference in transaminase decline between each subgroup. Low dose of glycyrrhizic acid( 90-100 mg·kg-1) has a toxicity-reduction effect on chronic hepatotoxicity induced by tripterygium( 0. 09-0. 10 mg·kg-1). Middle and high doses of glycyrrhizic acid( 120-480 mg·kg-1) have a toxicity-reduction effect on acute hepatotoxicity induced by tripterygium( 0. 6-1. 0 mg·kg-1),but with no significant dose-effect relationship.

BACKGROUND: BK virus-associated nephropathy (BKVN) is an important cause of chronic allograft dysfunction. The objective of our study was to evaluate the prognosis of BKVN. METHODS: We retrospectively reviewed the data of 133 renal transplant recipients with BKVN treated at the First Affiliated Hospital of Sun Yat-Sen University between July 2007 and July 2017. BK viral loads, graft function, and pathologic indexes were compared between initial diagnosis and last follow-up. RESULTS: After a mean follow-up period of 14.4 (range, 0.3-109.6) months after diagnosis of BKVN, BK viruria, and BK viremia become negative in 19.5% and 90.2% of patients, respectively. The mean estimated glomerular filtration rate (eGFR) at last follow-up was lower than at diagnosis of BKVN (18.3 ± 9.2 vs. 32.8 ± 20.6 mL·min·1.73 m, t = 7.426, P < 0.001). Eight (6.0%) patients developed acute rejection after reducing immunosuppression. At last follow-up, the eGFR was significantly lower in patients with subsequent rejection than those without (21.6 ± 9.8 vs. 33.5 ± 20.9 mL·min·1.73 m, t = 3.034, P = 0.011). In 65 repeat biopsies, SV40-T antigen staining remained positive in 40 patients and became negative in the other 20 patients. The eGFR (42.6 ± 14.3 vs. 26.5 ± 12.3 mL·min·1.73 m), urine viral loads (median, 1.3 × 10vs. 1.4 × 10 copies/mL), and plasma viral load (median, 0 vs. 0 copies/mL) were all significantly lower in patients with negative SV40-T antigen staining than those with persistent BK involvement (all, P < 0.05). Five (3.8%) recipients lost their graft at diagnosis of BKVN, and 13 (9.8%) lost their graft during the follow-up period. The 1-, 3-, and 5-year graft survival rates after diagnosis of BKVN were 99.2%, 90.7%, and 85.7%, respectively. Higher pathologic stage correlated with lower allograft survival rate (χ = 6.341, P = 0.042). CONCLUSION Secondary rejection and persistent histologic infection in BKVN lead to poor prognosis.

Objective To investigate the clinical value of preoperative lymphocyte-to-monocyte ratio(LMR)in evaluating the prognosis of patients with stage T1 non-muscle invasive bladder cancer(NMIBC).Methods A total of 215 patients with stage T1 NMIBC who underwent transurethral resection of bladder tumor were enrolled.Clinical data were collected.Patients were followed up and their disease-free survival(DFS)and overall survival(OS)were recorded.The receiver operating characteristic(ROC)curve of preoperative LMR in detecting patient prognosis was used to determine the optimal cut-off value for LMR.Patients were divided into low LMR group(LMR <3.86,=77)and high LMR group(LMR ≥ 3.86,=138).Kaplan-Meier survival curves were explored to compare cumulative DFS and OS rates in patients with different LMR levels,and COX proportional hazards regression model was used to analyze factors associated with DFS and OS.Results All these 215 patients with T1 stage NMIBC were followed up for 2-92 months,and the DFS rate was 59.07% and OS rate was 65.12%.Kaplan-Meier curves showed that the cumulative DFS rate(=4.784,=0.029)and cumulative OS rate(=7.146, =0.008)in the low LMR group were significantly lower than those in the high LMR group.Tumor size ≥ 3 cm(=1.398,95% :1.042-1.875,=0.025),pathological grade G3(=1.266,95% :1.026-1.563,=0.028),and LMR ≥ 3.86(=2.347,95% :1.080-5.101,=0.031)were independent factors associated with DFS in patients with stage T NMIBC.In addition,tumor size ≥ 3 cm(=1.228,95% :1.015-1.484,=0.034),pathological grade G3(=1.366,95% :1.017-1.834,=0.038),and LMR<3.86(=2.008,95% :1.052-3.832,=0.035)were independent factors associated with OS in patients with T1 stage NMIBC. Conclusion Preoperative LMR is an independent factor associated with patients' prognosis in T1 stage NIMBC.Patients with low LMR tend to have higher risk of NMIBC progression and death.

Objective To investigate the expressions,roles,and clinical significance of microRNA-365(miR-365)and E74-like factor 4(ELF4)in cervical cancer. Methods The expressions of miR-365 in normal cervical tissues(n=34),cervical intraepithelial neoplasia 1(CIN 1)(n=31),cervical intraepithelial neoplasia2-3(CIN 2-3)(n=37),squamous cell carcinoma of the cervix(SCC)(n=33),and three cervical cancer cell lines(C33A cells,Hela cells,and SiHa cells)were detected by real-time quantitative polymerase chain reaction(qPCR).Bioinformatic prediction and luciferase reporter gene assay were performed to verify whether ELF4 was a direct target of miR-365.Western blot and immunohistochemistry were used to detect ELF4 expression in cervical cancer cells and in different pathological cervix tissues.CCK8 assay was used to detect the effect of overexpression or inhibition of miR-365 on the proliferation of cervical cancer cells at different time points.The relationships among the miR-365 expression,ELF4 expression,and clinicopathological parameters of cervical cancer were analyzed by correlation analysis. Results qPCR results showed that compared with the normal cervical cell HcerEpic,the expressions of miR-365 in CIN1,CIN2-3,and cervical cancer tissues gradually decreased with the increased pathologic grade,and its expressions also decreased in different cervical cancer cell lines.The luciferase reporter gene assay confirmed that ELF4 was the direct target of miR-365.Western blot showed that the expression of ELF4 increased in all three cervical cancer cell lines compared with normal cervical epidermal cell(P=0.013,P=0.002,P=0.004).Immunohistochemistry showed that ELF4 expression was up-regulated in CIN and cervical cancer tissues.CCK8 assay showed that overexpression of miR-365 inhibited cell proliferation,while inhibition of miR-365 promoted the proliferation of three cervical cancer cells(P<0.05).Further analysis confirmed that there was a negative correlation between the expression levels of miR-365 and ELF4 in CIN2-3 and SCC(r=-0.351,P=0.045;r=-0.349,P=0.035).Clinical analysis showed that the expressions of both miR-365 and ELF4 were correlated with tumor size,pathological grade,and clinical stage in SCC(all P < 0.05).Conclusion The decreased expression of miR-365 in human cervical cancer cells relieves its inhibitory effect on ELF4,which promotes the proliferation of cervical cancer cells and the formation of tumor.
