ABSTRACT

Objective To observe the clinical effect of the method of Shugan-Yiqi-Yangyin treatment for the steroid-resistant nephrotic syndrome (SRNS). Methods A total of 80 patients with SRNS were divided into 2 groups by random number table method, 40 in each group. The control group received glucocorticoids combined with Tripterygium Glycosides;and the treatment group received Shugan-Yiqi-Yangyin on the basis of the control group, 3 month as a course. The 24 h urine protein quantitative (propagated), plasma albumin, blood lipid (total cholesterol, triglycerides), hemorrheology, blood urea nitrogen (BUN), creatinine (Cr), urinary inhibition C (Cys C) were detected before and after the treatment of two groups, and the clinical effect was compared. Results The total effective rate of the treatment group was 92.50% (37/40) and 82.50% (33/40) in the control group, and the difference was statistically significant (Z=-1.966, P<0.05). After the treatment, the 24 hPRO (1.03 ± 0.64 mg vs.2.81 ± 1.43 mg,t=3.025),Cys C(0.35 ± 0.41 mg/L vs.0.76 ± 0.51 mg/L, t=3.058) of the treatment group was significantly lower than those of the control group(P<0.05).The Alb(34.88 ± 2.17 mg vs. 31.69 ± 2.05 mg, t=2.986) of the treatment group was significantly higher than this of the control group (P<0.05), After treatment,the whole blood high shear viscosity(7.84 ± 1.42 mPa?s vs.8.94 ± 1.38 mPa?s,t=3.160),the whole blood low shear viscosity(4.55 ± 0.37 mPa?s vs.5.02 ± 0.44 mPa?s,t=3.825),plasma viscosity(1.33 ± 0.10 mPa?s vs.1.95 ± 0.26 mPa?s,t=2.981),hematocrit(0.28 ± 0.03 vs.0.34 ± 0.03,t=2.993),fibrinogen(3.96 ± 0.57 g/L vs.4.52 ± 0.47 g/L,t=4.863)of the treatment group were significantly lower than those of the control group(P<0.05).The TC(5.04 ± 1.72 mmol/L vs.6.99 ± 1.06 mmol/L,t=3.67),TG(1.4 ± 0.64 mmol/L vs.2.02 ± 0.31 mmol/L, t=3.040) of the treatment group were significantly lower than those of the control group (P<0.05). Conclusions The Shugan-Yiqi-Yangyin treatment for SRNS can obviously improve the symptoms,reduce the side effects of hormone of antagonism. The possible mechanisms are to restore kidney function, improve blood viscosity and lower blood lipid levels.

ABSTRACT

Objective To investigate the accumulation of mutations and single nucleotide polymorphisms ( SNPs) in the displacement loop ( D-loop ) of mitochondrial DNA ( mtDNA ) might be associated with cancer risk and disease outcome.Methods We obtained cancerous and noncancerous liver tissues from 49 HBV-related HCC patients at the Fourth Hospital of Hebei Medical University.mtDNA of the liver tissues was extracted with Mitochondrial DNA Extraction Kit.Mutation and polymorphism were confirmed by repeated analysis.We assessed the prediction power of D-loop SNPs in hepatocellular carcinoma ( HCC) patients.Results No mutation in these HCC patients had prediction power for post-operational survival, whereas one SNP site ( nucleotide 150 C/T ) was identified by the log-rank test for statistically significant prediction of HCC survival.In an overall multivariate analysis, allele 150 was identified as an independent predictor of HCC outcome.The length of survival of patients with allele 150C was significantly shorter than that of patients with allele 150T (relative risk, 0.246;95% CI, 0.070–0.861; P=0.028).Conclusions The analysis of genetic polymorphisms in the mitochondrial D-loop helps to identify patient subgroups at high risk of a poor disease outcome.

ABSTRACT

Objective To investigate the clinicopathological features, treatment modalities, and prognostic factors for survival in patients with urinary tract small cell carcinoma (UT-SCC).Methods A total of 25 patients treated from June 2000 to December 2014 were included in the retrospective study.The data included age, gender, primary tumors origins, stage, treatment modalities, progression-free survival (PFS), overall survival (OS), pathology and immunohistochemistry.Of these cases, 22 were male, and the other was female, whose age was 45-79 years (mean age 67).20 cases small cell carcinoma of bladder patients and 2 small cell carcinoma of prostate cancer patients were included.The number of small cell carcinoma in pelvis,ureter and retroperitoneal was 1 respectively.The patients with small cell carcinoma of the urinary tract were classified as disease and extensive disease.17 bladder small cell carcinomas were limited disease and 3 cases were extensive disease;Prostate small cell carcinomas were both extensive disease;The small cell carcinomas in pelvis, ureter were limited disease;The small cell carcinoma in retroperitoneal was extensive disease.10 bladder small cell carcinomas which were limited disease received radical cystectomy.6 of 10 patients received etoposide and cisplatnum (EC).4 of 10 patients received gemcitabine and cisplatnum (GC).7 bladder small cell carcinomas patients who with limited disease refused to receive radical cystectomy in which 2 patients received TURBT and 5 patients received TURBT followed chemotherapy.Both prostate small cell carcinomas received chemoradiotherapy.2 small cell carcinomas in upper urinary tract (pelvis and ureter) received radical nephroureterectomy with bladder cuff resection.The patient of retroperitoneal small cell carcinoma received percutaneous nephrostomy after biopsy.The progression-free survival (PFS) and overall survival (OS) of these patients are analyzed;the influence of TURBT with adjuvant chemotherapy and clinicopathologic characteristics were analyzed in median PFS and OS.PFS and OS were compared between groups as a function of time, using a Kaplan-Meier survival curve analysis and the log-rank significance test.All statistical tests were two-sided, and P values < 0.05 were considered statistically significant.Results 25 patients with a pathologic confirmation of UT-SCC,either by biopsy or surgery,were finally included.These patients were classified as pure UT-SCC (14) and Mixed UT-SCC (11).Mixed UT-SCC was defined as tumors containing both SCC and non-SCC components,regardless of the proportion of the latter.13 cases were strongly positive and 3 cases were weakly positive in neuron specific enolase (NSE) level.8 cases were strongly positive and 2 cases were weakly positive in CgA level.Patients with limited disease experienced a significant longer PFS and OS compared with extensive disease subjects (PFS 13.2 vs.7.8 x2=13.53 P<0.01;OS27.2 vs.12.7x2=19.88 P<0.01).Patients with bladder SCC showed a significantly higher median PFS and OS compared with patients with SCC of other parts of urinary tract (PFS 12.8 vs.8.2 x2 =12.00, P =0.001;OS 26.3 vs.13.2 x2 =14.45,P <0.01) .The two different chemotherapy regimens (GC and EC) have no influence on survival (PFS: 16.3 vs.12.5,x2 =3.34, P =0.07;OS 29.5 vs.22.8, x2 =1.66, P =0.198).TURBT followed by adjuvant therapy have no influence on survival (PFS 14.5 vs.12.0 t =1.30 P =0.251;OS 24.5 vs.28.4 t =0.50,P =0.636).Conclusions The primary tumors origins and stage may have influence on survival in patients with UT-SCC.Patients with bladder small cell carcinoma and limited disease experienced a longer survival.

ABSTRACT

<p><b>BACKGROUND</b>The mitochondrial displacement loop (D-loop) accumulates mutations and single nucleotide polymorphisms (SNPs) at a higher frequency than other regions of mitochondrial DNA (mtDNA). We previously identified disease risk-associated SNPs in the D-loop of chronic kidney disease (CKD) patients; in this study, we investigated the association of age-at-onset and D-loop SNPs in CKD patients.</p><p><b>METHODS</b>The D-loop region of mtDNA was sequenced in 119 CKD patients attending the Fourth Hospital of Hebei Medical University between 2002 and 2008. The age-at-onset curve of the CKD patients was calculated using the Kaplan-Meier method at each SNP site, and compared using the log-rank test.</p><p><b>RESULTS</b>The mean age of 119 CKD patients was (55.6±14.2) years, and 56.3% were males. The mean estimated glomerular filtration rate (eGFR) was (81.2±12.4) ml×min(-1)×1.73 m(-2), with 79.8% (n = 95) of patients having an eGFR <60 ml×min(-1)×1.73 m(-2). All participants had an eGFR >30 ml×min(-1)×1.73 m(-2). The age-at-onset for CKD patients who smoked was significantly lower than that of non-smoking CKD patients. The SNP sites of nucleotides 150C/T were identified for their association with age-at-onset using the log-rank test. The age-at-onset of patients with the minor allele T genotype was significantly lower than that of patients with the C genotype at the 150 SNP site (P = 0.010).</p><p><b>CONCLUSIONS</b>Genetic polymorphisms in the D-loop appear to be predictive markers for age-at-onset in CKD patients. Accordingly, the analysis of genetic polymorphisms in the mitochondrial D-loop may help identify CKD patient subgroups at high risk of early onset disease.</p>

ABSTRACT

Objective To study the gene mutation of fibroblast growth factor receptor 3 (FGFR3) and p53 in bladder cancer tissue and to explore their relationship with tumor recurrence. Methods DHPLC and PCR direct sequence were used to detect the mutation of FGFR3 and p53 in BTCC (n=98) and normal bladder mucosa (n=10). Genomic DNA of 98 BTCC was extracted. The exon 5-8 of P53 and the exon 7, 10, 15 were amplification by PCR. The products of PCR was screened by DHPLC to detect the mutation of the production. The results of the FGFR3 and p53 mutation were analyzed by Kaplan-Meier method and no recurrence survival rate was tested by log rank test. All the analysis were aim to explore the clinical biological value of the mutation of FGFR3 and p53. Results Mutation of FGFR3 in BTCC (44. 9%) was higher than normal bladder mucosa(0, P<0.01). Mutation in T_a-T_1 was 75. 6%(33/45) ,T_2 -T_4 was 26. 6%C10/53). Mutation in G_1 was84. 6%(11/13),inG_2 was 61. 4% (27/44), in G_3 was 14. 6% (6/41), (P<0. 05). The mutation rate was lower with the higher of stage and grade. Mutation of p53 in BTCC (34. 6%) was higher than normal bladder mucosa (0%) (P<0. 01). Mutation in T_a - T_1 was 20. 0% (9/45), T_2 - T_4 was 47. 2%(25/53). Mutation in G_1 was G_1 7. 7%(1/13), in G_2 18. 2%(8/44),in G_3 58. 1%(25/41) , (P<0. 05). The mutation rate was higher in the higher stage and grade. Kaplan-Meier method results revealed that mutation of FGFR3 indicating a favorable prognosis while mutation of p53 indicating a poor prognosis. As to the analysis of genotype, the type of FGFR3mut/p53wt had a relative longer recurrent interval (P<0. 01). Conclusions Mutation of FGFR3 indicated a relative longer recurrent interval, which revealed a favorable prognosis of BTCC. Mutation of p53 indicated a relative shorter recurrent interval, which revealed a poor prognosis.

ABSTRACT

Objective To discuss the clinicopathologic and imaging features of multilocular cystic renal eell carcinoma(MCRCC). Methods The data of 8 cases(5 men and 3 women)MCRCC classified according to 2004 WHO criteria were reviewed retrospectively.The tumor was incidentally found in 5 out of 8 cases.Renal ultrasound and CT scans were available in all 8 cases.CT or enhanced CT scans showed a well-defined cystid mass with irregular thickening wall or septa in 7 cases,without visible nodules found.For treatment,open or laparoscopic radical and partial nephrectomy was done in those cases. Results Postoperative pathological findings confirmed the diagnosis of MCRCC.The mean greatest diameter of the tumors was 5.6 cm.Microscopically,the wall and septa lined by one or several layers of clear cells were observed in all cases.The TNM stage of all 8 cases was T1 N0 M0.For pathologic grade,7 cases were G1 and 1 case was G2.Seven patients were followed up and remained tumor free during the average time of 8 months. Conclusions MCRCC is an uncommon subtype of RCC,it has a lower malignant potential and a better prognosis compared with other types of RCC according to the literature.Nephron-sparing surgery may be an appropriate treatment option for MCRCC.
