Objective To discuss the diagnosis and treatment of renal pelvic carcinoma associated with renal stone.Methods A total of 13 patients,aged from 49 to 73 years old and averaged 59years old.The history of renal stone was 16 years.13 patients accepted B ultrasound check and 1 was found soft tissue occupying.8 patients accepted IVU check and none was found soft tissue occupying.7 patients accepted CT scan and 4 were found soft tissue occupying.The fluorescence in situ hybridization (FISH) examination was done for 2 patients and both were positive.6 patients were found lesions at renal pelvis mucous membrane during the operation of percutaneous nephrolithotripsy,4 accepted radical operations of renal pelvic carcinoma and 2 patients accepted radical nephrectomy according to the biopsy pathology.4 were found soft tissue occupying before operation and accepted radical operation of renal pelvic carcinoma ultimately.1 patient suffered gross hematuria and renal insufficiency accepted the renal pelvic carcinoma vaporization under the ureteroscope.Results The pathology showed that 7 cases were transitional cell carcinoma,4 were transitional cell carcinoma combined squamous cell carcinoma (SCC) metaplasia and 2 were squamous cell carcinoma.6 of 8 patients' stone chemical composition were infection stone and 2 were calcic blended stone.3 patients were followed up 1 to 2 years and survival with no tumor recurrence.The tumor recurred 10 months of the patient accepted the operation of renal pelvic carcinoma vaporization and accepted vaporization again.1 patient bsuffered SCC and local lymph node metastasis.He died 13 months post-operation.Conclusions For the patient who had long history of stone,combining infection with symptoms of severe hematuria and postoperation hematuria,the possibility of renal pelvic carcinoma should be considered.CT scan and urine FISH may help for diagnosis.The biopsy should routinely perform for the doubtful mucosa lesion during the cavity stone operation.Early and timely diagnosis and operation is the key for the patients with pelvic carcinoma associated with renal stone.

Objective To estimate the influence of palmitic acid (PA) on the proliferation of and production of inflammatory mediators by a human keratinocyte line HaCaT.Methods Cultured HaCaT cells were treated with PA of eight concentrations (0-200 μmol/L) for 3-24 hours followed by the evaluation of cell proliferation by using the cell counting kit-8.According to the proliferation assay,four concentrations (75,100,125,150 μmol/L) of PA were selected and used to treat HaCaT cells for 24 hours,then,fluorescence-based immunohistochemical staining was performed to observe the nuclear translocation of nuclear factor (NF)-κB p65,enzyme linked immunosorbent assay (ELISA) to determine the level of interleukin (IL)-6 in the supernatant of culture medium,real-time PCR to detect the mRNA expressions of peroxisome proliferator-activated receptor oα (PPARα) and IL-6,and Western blot to quantify the protein expressions of PPARα as well as total and nuclear NF-κB p65.Those HaCaT cells receiving no treatment served as the control group.Statistical analysis was carried out by one-factor analysis of variance using the GraphPad Prism 5.0 software.Results The HaCaT cells treated with PA of 50-175 μ mol/L showed accelerated proliferation compared with the control HaCaT cells (all P ＜ 0.05).PA from 75 to 150 μmol/L enhanced the nuclear translocation of NF-κB p65,mRNA and protein expressions of PPARα,as well as the mRNA expression and supernatant level of IL-6 in a dose-dependent manner.The relative expression level of nuclear NF-κB p65 protein was 0.4536 ± 0.0173,0.5184 ± 0.0206,0.5333 ± 0.0231,0.6160 ± 0.0297,and the supernatant level of IL-6 was (31.5677 ± 0.2268),(32.3773 ± 0.4156),(32.9837 ± 0.0029) and (33.6890 ± 0.0936) ng/L,in HaCaT cells treated with PA of 75,100,125 and 150 μmol/L,respectively,compared to 0.3237 ± 0.0114 (all P ＜ 0.01) and (30.4577 ± 0.5131) ng/L (all P ＜ 0.01) in the control HaCaT cells,respectively.Conclusions PA can accelerate the proliferation of HaCaT cells,enhance NF-κB nuclear transfer,PPARα expression and IL-6 secretion in a dose-dependent manner within a certain concentration range,and may exert a promoting role in the activation and expression of some inflammatory factors.

Poxviruses, a type of ds-DNA viruses which mainly target at the epithelial cell, are the pathogens of human and animals. During the revolution of poxviruses, the viruses encode multiple proteins that regulate the immune system to monitor the viral reproductive cycle in host cells. The nuclear kappa B (NF-kappaB) pathway is essential to signal transcription in the innate immune system. Therefore, poxviruses have adopted different strategies to elude immune detection and destruction regulated by NF-kappaB. Further research in this field would help us develop preventive and therapeutic preparation for pox. Given the renewed interest in poxvirus, we review the current understanding of how the various classes of poxviralimmunomodulatory proteins target and manipulate the NF-kappaB pathway.

The aim of this study was to investigate the renal function in 149 patients receiving myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) from June 2005 to June 2010 in our hospital, and analyze the risk factors resulting in kidney insufficiency and experience in diagnose and therapy. The creatinine clearance (CrCL) and serial creatinine level were evaluated before and after allo-HSCT within 100 days and 1 year. Non-radiation conditioning regimens were used for any patients. The acute kidney insufficiency (AKI) was defined as at least a 1.5-fold rise in serum creatinine level after allo-HSCT within the first 100 days. The chronic kidney insufficiency (CKI) was defined as the creatinine clearance < basal level within 3 months to 1 year after allo-HSCT. The results showed that the kidney insufficiency was found in 41 patients, in which the incidence of AKI was 32/149 (21.5%). CsA, amphotericin B (P = 0.025) and ES (P = 0.022) were defined as risk factors for AKI. The incidence of CKI was 18/138 (13%). cGVHD (P = 0.013) and TA-TMA (P = 0.012) were associated with the development of CKI. The 2-year survival was lower in patients with kidney dysfunction than that in patients without kidney dysfunction (39% vs 74.1%, P < 0.001). The main factors resulting in kidney insufficiency were defined as infection (52%), GVHD (20%), TA-TMA (12%) and tumor relapse (12%). It is concluded that kidney insufficiency is an important complication of allo-HSCT. Careful monitoring kidney function, minimizing the use of amphotericin B, prophylaxis and effective treatment of fungal infection, GVHD and TA-TMA may be effective preventive measures to decrease the incidence of kidney insufficiency.

OBJECTIVETo analyze the specificity, sensitivity and receiver operating characteristic (ROC) curve of plasma elafin for diagnosis of skin acute graft-versus-host disease (aGVHD), and to explore its clinical diagnostic value.

METHODSIncidence of skin aGVHD from fifty-three patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) were observed prospectively in Guangdong General Hospital from Apr 2010 to Aug 2011. The plasma concentrations of elafin were detected by enzyme-linked immunosorbent assay (ELISA). Skin biopsies were taken from 28 patients with skin rash, and elafin expression in the skin was detected by immunohistochemistry. Positive expression was defined as significant staining of at 50% of the depth of the epidermis, excluding the granular cell layer and the acrosyringium.

RESULTSAmong 28 patients with skin rash, twenty-five were considered as skin aGVHD by clinical diagnosis, seventeen were confirmed as skin aGVHD by pathological biopsy. 11 cases were elafin positive by immunohistochemical staining. Elafin protein was overexpressed in aGVHD skin tissue (P = 0.001). Plasma concentrations of elafin were significantly higher in patients with skin aGVHD (positive) group than in those without skin aGVHD (negative) group (P = 0.005), among which there being no statistically significant difference in plasma elafin level between patients with grade I skin aGVHD group and negative group(P = 0.971), but being statistically significant difference compared patients with grade II-IV skin aGVHD group with those with grade I skin aGVHD group (P = 0.02) and with negative group (P = 0.008). Using the pathological diagnosis as the gold standard, the estimated specificity and the sensitivity of clinical diagnosis criteria were 27.3% and 100%, respectively, and those of tissue elafin protein level were 100% and 64.7%, respectively. The area under the ROC curve was 0.909 (0.797 - 1.021) when plasma concentrations of elafin was used in diagnosis of skin aGVHD. The sensitivity was 82.4% and the specificity was 81.8 % when the critical value was set at 1456.043 µg/L.

CONCLUSIONPlasma concentration of elafin is significantly higher at the onset of skin aGVHD. It can be used as biochemical marker of skin aGVHD and has higher value in diagnosis of skin aGVHD.

This study was purposed to investigate the efficacy and safety of intravenous injecting itraconazole (ITCZ) as empirical antifungal therapy in the patients with hematological malignancies. According to recommendation in IDSA guidebook, the patients suffered from fever during neutropenia and inefficacy of treatment using broad-spectrum antibiotics for 4 days should receive intravenous injection of ITCZ as empirical antifungal therapy. The results showed that the overall clinical response rate to ITCZ injection was 62.9% (22/35), and the success rate of achieving composite endpoints was 54.3% (19/35). Mild adverse reactions were observed in 6 patients (17.1%). The injection of ITCZ was stopped in 2 patents (5.7%) due to adverse reaction. Further analysis revealed that the response rate was higher in patients with fever prior to the start of ITCZ within five days than beyond five days (P = 0.031). The response rate was higher in patients with possible invasive fungus infection (IFI) than that in patients with probable and confirmed IFI (P = 0.002). The prophylactic antifungal treatment during neutropenia displayed no significant influence on efficacy of empirical antifungal therapy with itraconazole (P = 0.054). It is concluded that the good efficacy and safety of empirical ITCZ injection for hematological malignancies patients is efficient and safe.

Objective To investigate the curative effect of YU Yun pulse-feeling-based acupuncture therapy for the treatment of middle-late liver cancer. Methods A total of 60 middle-late liver cancer patients were divided into control group and treatment group by stratified randomization method,30 cases in each group. The control group was given integrated Chinese and western medicine therapy according to the clinical pathway, including anti-cancer treatment such as vascular interrention,molecular targeted therapy,chemotherapy,radio therapy, and focal ablation therapy,as well as chinese medicine treatment based on disease differentiation and syndrome differentiation. And the treatment group was given YU Yun pulse-feeling-based acupuncture therapy on the basis of treatment for the control group. The two groups received 12-week treatment, and then their curative effects were compared. Results The treatment group had better effect on increasing the survival rate, prolonging survival time, improving the scores of clinical symptoms, stabilizing tumor size, and increasing the scores of Karnofsky Performance Status (KPS)than the control group,the difference being significant (P < 0.05 or P <0.01). Conclusion YU Yun pulse-feeling-based acupuncture therapy exerts certain curative effect for the treatment of middle-late liver cancer.

OBJECTIVETo evaluate the effect and results of short and medium periods of follow-up of percutaneous balloon pulmonary valvuloplasty for critical pulmonary stenosis of neonates and infants under 6 months of age.

METHODSBetween January 2002 and December 2008, 34 consecutive patients aged from 13 to 175 days with critical pulmonary valvular stenosis underwent percutaneous balloon valvuloplasty. Patients records, catheterization data, angiograms and echocardiograms were reviewed. Patients were followed up for 6 months to 4 years (mean 25.5 months) by means of clinical examination and Doppler echocardiography.

RESULTSThe pulmonary valvuloplasty was accomplished in 32 (94%) of 34 attempts. Immediately after dilation, right ventricular systolic pressure (RVSP) decreased from (96 ± 28) mm Hg (1 mm Hg = 0.133 kPa) (49 ± 20) mm Hg (P < 0.01), the transvalvular peak to peak systolic gradient (ΔP) decreased from (89 ± 25) mm Hg to (25 ± 12) mm Hg (P < 0.01), and the right ventricular/aortic systolic pressure ratio decreased from 1.2 ± 0.5 to 0.7 ± 0.3 (P < 0.01). One patient died because of cardiac tamponade following rupture of the pulmonary valve annulus, 2 patients developed pericardial effusion, 3 patients had infundibular spasm, 3 patients had a pre-dilation by small balloon and 1 patient had weakened femoral artery pollex. After a follow up period of 6 months to 4 years 3 of 31 patients lost to follow-up. Repeat valvuloplasty was performed in 5 patients (3 neonates), no patient required surgery, and the other 23 patients did not undergo further intervention, a mean peak systolic Doppler gradient of (20 ± 13) mm Hg was found and no significant pulmonary regurgitation was seen.

CONCLUSIONSPercutaneous balloon pulmonary valvuloplasty was effective and safe for the treatment of critical pulmonary stenosis of neonates and infants under 6 months of age with good short and medium term results.

Objective To explore the causes of dengue fever resurgence in Guangxi, and to analyze the risk factors of dengue fever. Methods The descriptive epidemiological analysis was conduced based on the dengue fever data reported from 2006 to 2015, and the surveillance results of aedes and antibody levels in health population from 2013 to 2015 in Guangxi. Results Before 2013, dengue fever was imported from foreign country in Guangxi, accounting for 95.35％(42/45), and 75.71％of the imported cases was imported from Southeast Asia. The local outbreak of dengue fever was happened in 2014, accounted for 94.02％(849/903) of the total number of 10 years. From onset to diagnosis, Guangxi dengue fever cases need 0-70 d (median time interval is 6 d). Cases were reported year-round, but the peak season for the onset of dengue fever was from September to November, accounting for 96.46％of all cases (871/903). The number of cases reported in Nanning was the most (83.37％), followed by Wuzhou city (7.44％) and Guilin city (4.81％), and all the three cities had dengue fever outbreaks. The cases were mainly commercial service staff (27.80％) and houseworkers and unemployed people (18.16％). Results of aedes monitoring showed that the density of aedes was high in Guangxi. In more than 50％ of the monitoring seasons the breteau index (BI) stayed greater than 20. However, the antibody positive rate was only 3％ in the healthy residents of Guangxi. Conclusion The risk of dengue fever is high in Guangxi. Therefore, it is essential to emphasizing idea of prevention and control, strengthening immigration surveillance, improving diagnosis ability, enhancing public health education, and expanding monitoring range.

OBJECTIVETo screen and identify differentially expressed genes between a fertile patient and another infertile patient who belonged to a large Chinese pedigree affected with androgen insensitivity syndrome (AIS).

METHODSWe constructed the forward and reversed subtracted libraries using genital skin fibroblasts (GSF), which were obtained from the fertile patient MJ and infertile patient ZGJ, as tester respectively. Candidate clones were screened with colony in situ hybridization, dot blot, and Southern blot analysis step by step and conformed with Northern blot analysis. The potential positive clones were sequenced and the homology of the sequences was analyzed.

RESULTSThe forward and reversed subtracted libraries containing differentially expressed pattern of two GSF cell lines were constructed. Two positive clones identified by Northern blot were obtained in the reversed subtracted library. Eleven candidate clones from the two libraries that failed to hybridize with both RNA populations were obtained simultaneously, which might represent differentially expressed low abundance transcripts. Sequencing results and homology analysis demonstrated that the two positive clones were significantly homologous with the genes of autotaxin-t and calcium binding protein calcyclin (S100A6), respectively.

CONCLUSIONSTwo positive clones and eleven clones showing no hybridization signals may represent differentially expressed genes between the two GSFs. This finding may be useful to elucidate the molecular mechanisms leading to phenotypic variation and preserved fertility of the AIS pedigree.
