SUMMARY To explore the clinical pathological characteristics and improve the recognition in the diag-nosis and treatment of basal cell carcinoma (BCC)of prostate.Three cases of BCC of prostate were re-ported and the relevant literature was reviewed to investigate the diagnosis and treatment of this disease. We analyzed three cases of prostatic BCC.Their ages were within a range of 57 to 83 years.One of them complained of hematuria and two complained of dysuria.All of them presented with prostatic hyperplasia. Two of them presented with high prostate specific antigen (PSA)and one with normal PSA.Case 1 had prostate cancer invasion of bladder,rectal fascia,with lymph node metastasis,bone metastasis and lung metastases.The patient received bladder resection +bilateral ureteral cutaneous ureterostomy +lymph node dissection on November 2,2014 .Postoperative pathological diagnosis showed BCC.Reexamination of pelvic enhanced MRI in January 8,2015 suggested pelvic recurrence.Abdominal enhanced CT showed multiple liver metastases and pancreatic metastasis on July 11,2015.Prostate cancer specific death occurred in October 2015.Case 2 was diagnosed as BCC in prostate biopsy on March 27,2015. Positron emission tomography and computed tomography (PET-CT)showed pulmonary metastasis and bone metastasis.Then the patient received chemotherapy,endocrine therapy and local radiation therapy. Reexamination of PET-CT on January 11,2016 showed that the lung metastase tumors and bone metas-tase tumors were larger than before.Up to January 10,2016,the patient was still alive.Postoperative pathological changes of transurethral resection of prostate (TURP)in case 3 showed BCC might be con-sidered.The PET-CT suggested residual prostate cancer,which might be associated with bilateral pelvic lymph node metastasis.In April 20,2016,the review of PET-CT showed pelvic huge irregular hybrid density shadow,about 14.5 cm ×10.0 cm ×12.9 cm in size,and tumor recurrence was considered. Then the patient received local radiation therapy.The patient survived in the followed upon January 10, 2016.BCC of prostate is a rare subtype.Due to the local infiltrative and distant metastatic potentiality, active management is preferred and a life-long follow-up is necessary.

By retrospectively reviewing the current status of traditional Chinese medicine (TCM) and Western medicine treatments of chronic nonbacterial prostatitis (CNP), the TCM understanding of its etiologies and pathogenesis, the therapeutic principles and the mechanisms of acupuncture treatment of CNP, the clinical study strategies of acupuncture treatment for CNP were further proposed, which could provide more scientific basis and support for the definite longer-term therapeutic efficacy of acupuncture treatment of CNP. Breakthrough in the treatment of CNP will be achieved with the application of acupuncture therapy both in clinical practice and experimental research.

OBJECTIVETo investigate the relationship between the resistance index (RI) of the renal artery and serum creatinine (Cr) level in patients early (within one month) after renal transplantation.

METHODSA total of 123 patients receiving renal transplantation underwent examinations by color Doppler ultrasound for measurement of the RI of the renal artery within one month after the operation. According to the results of RI measurement, the patients were divided into RI≥0.75 and RI<0.75 groups for analyzing the correlation between RI and serum Cr level measured at the same time points.

RESULTSThe RI and Cr levels in patients with RI≥0.75 showed a significant positive correlation (P<0.05), whereas they showed an inverse correlation in patients with RI<0.75 (P<0.05). The patients with RI≥0.75 had significantly lower RI of the renal artery and Cr level than those with RI≥0.75.

CONCLUSIONRI is significantly correlated to Cr, and may serve as an indicator for predicting renal graft function after transplantation.

OBJECTIVETo understand the changing trend of occupational hazard of industries in Shunde area and to provide the scientific evidence for the prevention of occupational diseases.

METHODSThe pre-evaluation of occupational hazard was carried out for the construction projects. The data about employee number scale, industry species, occupational hazard factors, hazard levels and prevention measures for construction projects were collected and analyzed. The data of Shunde Occupational Health Survey in 2011 served as the control data.

RESULTSThere were 258 construction projects in 2010 and 2011, in which the proportions of medium and large scales increased to 8.1% and 2.4% respectively, the proportions of the furniture and chemical industries decreased from 25.6% or/and 5.1% to 2.7% or/and 1.8%, the proportions of the high-tech industries increased from 1.8% to 9.2%. The proportions of the projects with serious, medium and slight occupational hazard levels were 4.3%, 67.8% and 27.9%, respectively. The proportions of the projects with harmful chemicals, dusts and physical factors were 34.2%, 46.8%, 42.6%, respectively.

CONCLUSIONThe feature of occupational hazard in Shunde industries has changed at upgrading stage. We should pay attention to the prevention of occupational diseases in high-tech industries.

OBJECTIVEIdiopathic nephrotic syndrome (INS) is a common glomerular disease. The pathogenesis of the disease remains unclear. Recent studies indicate that transforming growth factor beta (TGF beta) is the main cytokine involved in glomerular disease. It plays an important role in the development of INS and in occurrence of glomerulosclerosis. The present study aimed to study changes and significance of TGF beta in children with idiopathic nephrotic syndrome (INS).

METHODSTotally 35 cases with INS (13 males, 22 females) were studied. The age of onset was between 2 years and 1 months and 14 years with an average of 8 years and 3 months. The active stage group had 35 cases and the remission stage groups had 25 cases. The cases in active stage group had first onset of the disease with obvious clinical symptoms and abnormal laboratory findings without use of corticosteroids. The cases in remission stage group were asymptomatic without abnormal laboratory findings. Protein in urine was negative over 4 weeks after oral administration of prednisone for 8 weeks. Twenty five cases were steroid responsive and 10 cases were steroid non-responsive among the 35 cases. Thirty healthy young children were enrolled as control. TGF beta was detected by ELISA in peripheral blood mononuclear cell (PBMC) culture medium. The TGF beta mRNA gene expression was measured by in situ PCR in PBMC.

RESULTS(1) Concentration of TGF beta(247 +/- 26) ng/L and TGF beta mRNA expression (0.57 +/- 0.18) in active stage of simple type or nephritis type INS were higher than those of remission stage and control (P < 0.01). Concentration of TGF beta[(125 +/- 16) ng/L] and TGF beta mRNA expression (0.30 +/- 0.12) in remission stage were higher than that of control (P < 0.05). (2) The level of TGF beta protein in nephritis type [(275 +/- 26) ng/L] was significantly higher than that in simple type [(220 +/- 18) ng/L] in active stage INS (t = 6.45, P < 0.01). No significant difference in TGF beta mRNA expression was found between the nephritis type (0.58 +/- 0.15) and simple type (0.55 +/- 0.16) in active stage INS, either (P > 0.05). But these two types were different from the control (P < 0.01). (3) Concentration of TGF beta and TGF beta mRNA expression after therapy was clearly lower than that before therapy in steroid responsive group (P < 0.01). Whereas no significant change was seen in steroid non-responsive group. Both indicators were higher in steroid non-responsive group than in steroid responsive group whether before or after therapy.

CONCLUSIONTGF beta may play an important role in the mechanism of INS and its level in PBMC can be used as an immunological indicator for the illness state, therefore, determination of TGF beta level and mRNA may be of some clinical significance.

OBJECTIVETo study the antigenic properties of mutant hepatitis B virus surface antigen, to understand the sensitivity of the commercially available HBsAg assays to the variants and to reduce the undetectability of the variants.

METHODSRecombinant eukaryotic expression plasmids for HBsAg. The recombinant eukaryotic expression plasmids pSS1adr, pSS1adw2, pSS1adw2- 145Arg, pSS1adr-126 Asn and pSS1adr-126Ser were transfected into COS-7 cells. HBsAg in the supernatants of transfected cells was detected by using different commercial ELISA kits.

RESULTSThe absorbance value of pSS1adr-126 Asn and pSS1adr-126Ser plasmids were similar to that of the wild type HBsAg, the absorbance value of pSS1adw2-145Arg plasmids was lower than that of the wild type HBsAg.

CONCLUSIONIt is estimated that the antigenicity of HBsAg mainly depended on the amino acid sequence of "a" antigen determinant and its conformation, so 145 amino acid substitutions led to the change of conformation and the antigenicity of variant HBsAg was lower than that of the wild type.

OBJECTIVE The purpose of the present study was to investigate the impact of fluvas-tatin formulation on the pharmacokinetics-genetic polymorphis relationship. METHODS We compared the difference between the pharmacokinetics of fluvastatin as an extended-release (ER) 80 mg tablet and an immediate-release(IR)40 mg capsule in terms of drug metabolism enzyme and transporter ge-netic polymorphisms. In this open-label, randomized, two-period, two-treatment, crossover study, ef-fects of BCRP, SLCO1B1, MDR1, CYP2C9, and CYP3A5 polymorphisms on the pharmacokinetics of fluvastatin were analyzed in 24 healthy individuals.Each treatment duration was 7 days with a washout period of 7 days between the crossover.Serum concentration of fluvastatin was evaluated using high-performance liquid chromatography-tandem mass spectrometry. RESULTS The SLCO1B1 T521C genotype had no statistically significant effect on IR 40 mg capsule of fluvastatinafter single or repeated doses.However,for the ER 80 mg tablet,the SLCO1B1 T521C genotype correlated with the AUC0-24of repeat doses (P=0.01). The CYP2C9*3 genotype correlated with the AUC0- 24after the first dose IR 40 mg capsule (P<0.05); however, the difference between CYP2C9*1/*1 and CYP2C9*1/*3 was not statistically significant after repeated doses. CONCLUSION The effect of SLCO1B1 T521C on fluvas-tatin exposure was observed and was more profound in ER and repeated dose administration than in IR and single dose administration.We recommend that formulation should be incorporated into future pharmacogenomics studies and clinical implication guidelines.

OBJECTIVETo investigate if WAVE1 is involved in mult drug-resistance (MDR) of human leukemia cell line K562/A02.

METHODSThe level of WAVE1 in K562 and K562/A02 cells was assayed by Western blot and RT-PCR; K562 cells and K562/A02 cells were transient transfected with pEFBOS-WAVE1 reconstructed plasmid or specifically siRNA to WAVE1. 50% inhibition concentration (IC50) of doxorubicin on K562/A02 was determined by WST-8 assay. Hoechst33258 staining was used to examine cell morphological changes and to calculate percentage of apoptotic nuclei. The mRNA level of mdrl was assayed by RT-PCR. The Bcl-2 protein was assayed by Western blot.

RESULTS1. The WAVE1 expression at mRNA and protein level in K562/A02 cells was increased by about 70% and 63% respectively as compared with that in K562 cells. 2. Overexpression of WAVE1 in K562 cells by transient transfection significantly increased the resistance to doxorubicin, and increased IC50 from (0.05 +/- 0.00) microg/ml to (2.99 +/- 0.12) microg/ml, and at 1 microg/ml or 5 microg/ml of doxorubicin treatment, cell apoptotic nuclei rate was decreased by 30% or 35% respectively. 3. Suppression of WAVE1 in K562/A02 cells by siRNA resulted in a reversal of MDR to doxorubicin, and decreased IC50 from (4.29 +/- 0.15) microg/ml to (1.85 +/- 0.07) microg/ml, and at 1 microg/ml or 5 microg/ml of doxorubicin treatment, cell apoptotic nuclei rate was increased by 24% or 21% respectively. 4. Overexpression of WAVE1 in K562 cells significantly increased the mdrl mRNA and the Bcl-2 protein, and suppression of WAVE1 in K562/A02 cells by siRNA decreased the mRNA and the protein.

CONCLUSIONWAVE1 involves in the MDR mechanisms in K562/A02 leukemia cells through regulation the level of mdrl and Bcl-2.
