OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Affinity chromatography is a chromatographic method for separating molecules using the binding characteristics of the stationary phase with potential drug molecules. This method can be performed as a high throughput screening method and a chromatographic separation method to screen a variety of active drugs. This paper summarizes the history of affinity chromatography, screening technology of affinity chromatography, and application of affinity chromatography in screening bio-active compounds in herbal medicines, and then discusses its application prospects, in order to broaden applications of the affinity chromatography in drug screening.

Chemokines are small cytokines with chemotactic activity, they are involved in regulating immune responses and inflammatory responses. In the development of tumors, chemokines are multi-functional mediators that not only affect the infiltration of immune cells into the tumor, but also have an important impact on tumor growth, angiogenesis, invasion, and metastasis. Besides, they are important targets of tumor therapy. Here we review chemokines involved in the regulation of signaling pathways, analyze the mechanism of chemokines in the development of breast cancer, summarize the chemokines targeted drugs for breast cancer in recent years and make a prospect about the role of chemokines in anti-breast cancer therapy.

Objective To estimate the predictive value of neutrophil gelatinase-associated lipocalin in urine (uNGAL) for detection of acute kidney injury (AKI) in the intensive care unit (ICU) critically ill patients.Methods A total of 110 patients from the ICU of three general hospitals were enrolled in the study.The patients were adults more than 18 years of age.After admitted to ICU,the patients were continuously observed for 72 hours.According to the RIFLE criteria for diagnosis of AKI,the patients were classified as AKI group (33 cases) or non-AKI (77 cases).According to the sepsis diagnostic criteria,the patients were classified as sepsis (79 cases) or non-sepsis (31 cases).Exclusion criteria of patients were chronic renal insufficiency,malignant tumor,death after admitted to ICU 24 hours.Serum creatinine and uNGAL of the patients were analyzed daily.The difference of uNGAL between sepsis and non-sepsis patients,AKI and non-AKI patients,sepsis non-AKI and sepsis AKI patients was compared.Moreover,the difference of serum creatinine and uNGAL between AKI and non-AKI patients into ICU 24 h was compared,and the sensitivity and specificity of uNGAL and serum creatinine for diagnosis of AKI in the ICU patients were evaluated using ROC curve.Results The uNGAL levels were all significantly different between sepsis and non-septis patients,AKI and non-AKI patients,sepsis concomitant AKI and sepsis without AKI patients.The uNGAL levels were significantly different between AKI and non-AKI patients in ICU for the first 24 h,while the difference of serum creatinine were not significant.The area under receiver operating characteristic (ROC) curve of uNGAL and serum creatinine of patients in ICU for the first 24 h were 0.828 (95％ CI:O.742-0.914) and 0.583 (95％ CI:0.471-0.695),respectively.The cutoff value of uNGAL was 170 ng/ml,and the sensitivity and specificity were 0.778 and 0.784,respectively.The sensitivity was superior to serum creatinine.Conclusions uNGAL was superior to serum creatinine in the diagnosis of AKI,and could be used as a marker of the early diagnosis of AKI.

Objective To investigate the expressions of intermedin /adrenomeduliin 2 (IMD/AM2) and its receptor calcitonin receptor-like receptor (CRLR) in the kidney of rats after renal ischemia reperfusion injury(IRI). Methods Male Wistar rats were divided randomly into two groups: sham group and operation group. Renal IRI model was induced by clamping both renal arteries. Blood and kidney were harversted at 0 h, 6 h, 12 h, 24 h, 48 h, 72 h after reperfusion, respectively. Renal histological changes were semi-quantitated. Expressions of IMD and CRLR in the kidney were detected by Western blot, and the content of IMD in serum was measured by radioimmunity at 12 h, 48 h, 72 h after repeffusion. Results Kidneys of renal IRI model rats displayed significant pathologic changes, and the changes were much severer at 48 h after reperfusion. The expressions of IMD and CRLR in kidney were significantly up-regnlated at 12 h, 48 h, 72 h after renal IRI (P<0.01). The level of IMD in serum increased at 12 h, 48 h, 72 h after renal IRI (P<0.05). Conclusion The expressions of IMD and its receptor are up-regulated in the kidney after renal IRI, which may participate in the pathophysiological changes induced by renal IRI.

OBJECTIVETo explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.

METHODSWe transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.

RESULTSAt 3 days, inverted microscopy revealed a transfection efficiency of > 80%. At 7 days, the STIM1 expression was significantly inhibited at both mRNA and protein levels. The Bcl-2/Bax rate was remarkably decreased as compared with that of the control group (0. 31 vs 1.24 ) , and the survivin expression was markedly reduced, 0. 14 times that of the relative expression in the control. However, the Caspase-3 cleavage was significantly activated, 1.52 times that of the control (P <0.05).

CONCLUSIONSTIM1 can be regarded as an oncogene in prostate cancer PC-3 cells. Inhibition of its expression can induce PC-3 cell apoptosis by reducing the Bcl-2/Bax rate, decreasing the survivin expression, and activating the Caspase-3 pathway.

0.05).Compared with control group,significant decrease in positive group was found in the interval from first evacuation of HM to resolution of serum ?-hCG level,(83?18) days versus(126?31)days(P0.05).Conclusions Once HM is diagnosed,evacuation should be performed as soon as possible,the later the evacuation begins,the higher the risks of lung metastasis and chemotherapy are.It is not necessary to worry about lung metastasis before evacuation of HM,the outcome of post- chemotherapy is very good.
