Objective To improve the diagnosis and treatment of xanthogranulomatous pyelonephri- tis(XGP).Methods The clinical data of 18 cases(5 males and 13 females;mean age,47 years)with XGP were analyzed.Of them,6 had the lesion on the left,and 12 on the right.Before operation,XGP was mis- diagnosed as renal calculus with hydronephrosis in 4 cases,ureteral calculus with severe hydronephrosis in 3 cases,renal tuberculosis in 3 cases and renal carcinoma in 8 cases.Results Of the 18 cases,7 were diag- nosed to have XGP by frozen section during operation and 11 cases had a definite diagnosis by pathological examination after nephrectomy.After a follow-up of 6-124 months,no recurrence was observed in all these 18 cases.Conclusions Preoperative diagnosis of XGP is difficult.This disease is clinically characterized by foam cells in urine smear,low-density value of kidney CT and ineffective antibiotic therapy.Combined a- nalysis of clinical data and improvement of clinical recognition of XGP is the key to avoiding delayed diagno- sis or misdiagnosis of XGP.

Objective To evaluate and compare the efficacy of holmium laser enucleation of the prostate(HoLEP) and plasmakineticenucleation of the prostate(PKEP) for treating benign prostatic hyperplasia (BPH).Methods A total of 86 cases of BPH were selected from the Shandong Energy Zibo Mining Group Co.Ltd Central Hospital from January 2013 to June 2014.The patients received either HoLEP (40 cases) or PKEP(46 cases) treatment.Clinical data including postvoid residual volume (PVR),international prostate symptom score(IPSS),quality-of-life score(QOL score),maximum urinary flow rate (MFR) were evaluated before and 3 months after operation.Blood loss in operation,operation time,weight of resected prostate tissue,bladder irrigation time,catheterization time and length of hospital stay were also collected from the perioperative period.Results Three months after surgery,PVR,IPSS,QOL and MFR were all significantly improved in both HoLEP and PKEP groups compared with the data before operation (P =0.000),while there was no significant difference between the two groups(P>0.05).Patients from the HoLEP group showed markedly lower values of bone loss in operation than that of PKEP group((69.5±23.6) ml vs.(87.5±38.0) ml,P=0.011).There were no significant differences in terms of other indexes (P> 0.05).Conclusion HoLEP and PKEP have similar efficiency in treating BPH,while HoLEP is suggested superior in regard of bone loss.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.
METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.
RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.
CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

Objective To explore the interaction between serum melatonin and the status of disease and probe the effect factor of serum melatonin change in asthmatic children.Methods Serum melatonin was measured in asthmatic children with 15 cases of mild persistent asthma,15 cases of moderate persistent asthma,15 cases of severe persistent asthma,15 cases of stable asthma and 15 cases of normal subjects by enzyme-linked immunosorbent assay(ELISA).Results The levels of serum melatonin in the 5 groups of mild persistent asthma,moderate presistent asthma,Severe Persistent asthma,Stable asthma,control subject were(22.76?5.16)ng/L,(16.79?3.35)ng/L,(11.54?1.45)ng/L,(22.06?3.36)ng/L,(28.72?4.32)ng/L,respectively.There were significant differences between any of them(Pa

Objective To evaluate the clinical and pathological factors that may influence serum prostate specific antigen(PSA)level in patients with benign prostatic hyperplasia(BPH).Methods A total of 561 cases of BPH diagnosed by pathological examination following operation were analyzed retrospec- tively.The patients'mean age was(68.3?6.3)years.The International Prostate Symptom Score(IPSS)was 21.1?7.4;the quality of life(QOL)was 4.5?0.8;Qmax was(7.3?3.3)ml/s;prostate volume(PV) was(69.8?36.8)ml;andpost-void residue(PVR)was(81.9?105.8)ml.Results Of 561 cases,223 cases(39.8%)had serum PSA level at 4-10 ng/ml,and 91 cases(16.2%),over 10 ng/ml.The level of serum PSA was not significantly associated with age,IPSS,QOL,Qmax and PVR(r=0.08,0.03,0.06,0.04 and 0.09,respectively;P>0.05),but significantly associated with prostate volume of BPH(r=0.42,P<0.01).The level of serum PSA was significantly elevated in BPH patients with enlarged prostate volume (F=93.45,P<0.05)and the history of acute urinary retention(x~2= 59.1,P<0.01).Additionally,a significantly increased PSA level was noted in tissue specimens with glandular hyperplasia(x~2=16.14,P<0.01)or necrotic loci in BPH patients(x~2=36.06,P<0.01).Conclusions An elevated serum PSA level was observed in more than 50% of BPH patients undergoing surgical resection.Enlarged prostate volume,the history of acute urinary,retention,and tissue specimens with glandular hyperplasia or necrotic foci are considered to be the main causes leading to elevated PSA level in BPH patients.

As one of the most serious types of psoriasis, pathogenesis of erythrodermic psoriasis (EP) is unclear so far. In this study, we aimed to detect the levels of Th1/Th2 cytokine-associated transcription factors and T-lymphocyte clone in peripheral blood mononuclear cells (PBMCs) derived from EP patients, and gene expression level of T-bet/GATA-3 in skin lesion. The potential role of Th1/Th2 reaction pattern played in the pathogenesis of EP was also discussed. Serum levels of IFN-γ, IL-2, IL-4 and IL-10 were quantified by ELISA among 16 EP patients, 20 psoriasis vulgaris (PV) patients and 15 healthy controls. The expression levels of T-bet/GATA-3 in the skin lesion and PBMCs were examined by real-time qPCR. The ratio of Th1/Th2 was measured by flow cytometry. The levels of IFN-γ, IL-2, IL-4 and IL-10 were higher in EP patients than in the healthy controls. The levels of IL-4 and IL-10 were 69.44±11.45 and 12.62±4.57 pg/mL, respectively, in EP patients, significantly higher than those in PV patients and healthy controls (P<0.05). Flow cytometry revealed the levels of both Th1 and Th2 in PBMCs from EP patients were higher than those in healthy controls, and the Th1/Th2 ratio was dramatically lower than in PV patients (P<0.01). The ratios of IFN-γ/IL-4 and T-bet/GATA-3 in EP patients were both less than 1.0, suggesting a reversal when compared with the other two groups. Our study indicated that the EP patients exerted a Th1/Th2 bidirectional response pattern, and the balance of Th cell subsets inclines to Th2, which might be one of the important mechanisms of EP pathogenesis.
