Objective To improve the management of the complications in patients with advanced prostate cancer. Methods Bone pain, anemia, urinary tract obstruction, hematuria and edema in the lower extremities and scrotum of patients with prostate cancer were managed with analgesics(24 cases), bisphosphonates(14 cases), isotope strontium-89(6 cases), external beam irradiation(9 cases), blood transfusion(9 cases), TURP(7 cases), superpubic cystostomy(8 case), percutaneous nephrostomy(4 case) and cysto-irrigation(6 case). Results 16 patients were alived and 10 were died of respiratory or circulation failure . The patients were relieved from pain and the other complications for several months after the palliative measures had been taken. Conclusions Bone pain, anemia, urinary tract obstruction and hematuria are common complications of advanced prostate cancer. They may have great impact on the life quality of patients. Diverse therapeutic modalities should be employed to palliate these disabling symptoms.

Objective To study in vitro anti-HIV activity of an extract of herb medicines,SanJiangDan,and the possible mechanism.Methods The main active ingredient of SanJiangDan was extracted by distillation.Three subtypes of HIV pseudovirus (B subtype,C subtype,CRF01_AE subtype) were used to evaluate the anti-HIV activity of SanJiangDan extract in vitro.The possible mechanism was evaluated through analyzing the effects of SanJiangDan extract on the expression of surface receptors and cytokines by T cells.The cytotoxicity of SanJiangDan extract was detected by using four different sources of cell lines including epithelial cells Caco-2 cells,TZM cells,Huh7 cells derived from liver cells and lymphocyte Jurkat-T cells.Results SanJiangDan extract effectively inhibited the infection of HIV pseudoviruses at concentrations of 1.6 mg/ml and 0.16 mg/ml.The inhibition rates were 30.9％,36.6％ and 65.0％ for B subtype,C subtype and CRF01_AE subtype respectively at the concentration of 0.16 mg/ml.As the concentration increased to 1.6 mg/ml,the inhibition rates increased to 96.4％ (B subtype),97.4％ (C subtype) and 99.5％ (CRF01_AE subtypes),but no toxicity to host cells was detected.Moreover,SanJiangDan extract inhibited the expression of HIV surface receptors including CD4,CXCR4 and CCR5 on TZM-bl cells,but enhanced IL-2 production.Conclusion SanJiangDan extract could inhibit HIV pseudovirus infection without causing cytotoxicity to host cells in vitro.The possible mechanism might be associated with the reduced expression of CD4,CXCR4 and CCR5 and enhanced secretion of IL-2 as well.

Objective To investigate the clinical value of serum VEGF levels in the diagnosis and treatment of colon cancer.Methods Serum VEGF was detected by ELISA,and CEA and CA199 concentration were detected by CLEIA in 66 patients with colon cancer,55 patients with colon benign diseases and 50 health persons.The value of individual and joint detection for VEGF in colon cancer was evaluated.Analysis had been done on relationships between serum VEGF and pathology,treatment effects and prognosis.Results The levels of serum VEGF in colon cancer group [(318.5±148.6) ng/L] were significantly higher than those in control group [(125.7±49.4) ng/L] and benign colon diseases [(136.9±52.6) ng/L] (t =8.830,8.805,all P ＜ 0.01).There was a positive correlation between serum levels of VEGF and depth of tumor size,tumor invasion,lymph node metastasis and TNM stage (P ＜ 0.01).The susceptibilities of VEGF,CEA,CA199 were 61％,45 ％,53 ％.The sensitivity of detection was improved to 86 ％ when the combined detection of VEGF,CEA and CA199 (x2 =11.237,P ＜ 0.01).The serum levels of VEGF in patients with colon cancer was significantly decreased after treatment in the 3,7,10 day compared with that before operation [(272.3±88.1),(236.8±77.4),(173.1±59.9) vs (318.5±148.6) ng/L,t=2.173,P ＜ 0.05; t =3.961,P ＜ 0.01; t=7.464,P ＜ 0.01],respectively.Conclusion The VEGF was related to the onset and progression and metastasis of colon cancer.It has clinical significancy for diagnosis of colon cancer and judgment of curative effect and prognosis.

Objective To evaluate the safety and clinical efficacy of finasteride in treating patients with benign prostatic hyperplasia (BPH) during a 14-year period in a hospital.Methods Forty-one patients with BPH receiving finasteride 5 mg daily for the treatment from December 1994 to Febrary 2009 were included in the study. The base line and the end of study data of nocturia, prostate volume, serum creatine, complete blood count and serum prostatic specific antigen (PSA) were recorded. The acute urinary retention, surgical treatment and drug adverse reaction (prostate cancer or breast cancer) during the observation periods were recorded as well.ResultsAll the 41 cases took finasteride regularly for long-term medical therapy of BPH. At the end of this study, the average age of patients was (87.9±5.4) years old and the average duration of treatment was (141.1±27.1) months. The numbers of nocturia were 1.8±1.5 and 3.2±1.3 pre- and post- treatment, respectively (t= -4.52,P<0. 05). Before and at the end of the study, the prostate volumes were (44.9±26.6) ml and (42.8±31.3) ml, respectively(t=0. 33,P>0.05). Stratified study showed that, compared with the baseline data, the prostate volume was increased by 17.3 ％ in patients with prostate volume <25 ml(t= -0. 88 ,P>0. 05) ; the prostate volume was decreased by 17.2％ in patients with prostate volume of 25-40 ml(t=2.59,P<0.05); the prostate volumes were (63.3±28. 9) ml and (62.6±36.5) ml pre- and post-treatment in patients with prostate volume > 40 ml, and there was no significant change(t= 0.07, P>0. 05). Before and after the treatment, the serum creatine levels were (96.8±18. 6) mol/L and (86.45±32. 3) mol/L, respectively(t= 1.79, P>0. 05) ; the white blood cell counts were (6.4±1.5) × 109 L and (6.0±1.7) ×109 L, respectively (t= 1.13,P>0. 05) ; and the PSA levels were (1.2±2.0) μg/L and (1.4±1.7) μg/L, respectively (t=-0. 49,P>0. 05). Three cases (7.3％) occurred acute urinary retention. There was no prostate cancer and breast cancer case, and no new adverse event occurred during long-time use of finasteride. Conclusions This retrospective study has demonstrated that the clinical progress of BPH can be controlled effectively by long-term administration of finasteride.
