OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).
METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.
RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).
CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.

Background and purpose: Arginase-1 (Arg-1) is an enzyme involved in the urea cycle. Research has shown that changed expression of Arg-1 plays an important role in the cellular metabolism and growth. The purpose of this research was to investigate the expression of Arg-1 in hepatocellular carcinoma (HCC) and to analyze its correlation with clinicopathological features. Methods: The expression of Arg-1 protein and mRNA in 31 samples of HCC, paracancerous liver tissues and 12 samples of normal liver was detected by Western blot and reverse transcription-polymerase chain reaction (RT-PCR). The expression profiles of Arg-1 at protein level in 158 samples of HCC and paracancerous liver tissues were detected with high-throughput tissue microarray technique and immunohistochemistry. The relationships between Arg-1 expression and clinicopathological features were also analyzed. Results:The expression of Arg-1 mRNA and protein was signiifcantly decreased in HCC compared with the paracancerous liver tissues and normal liver tissues (F=57.83, 160.89; all P<0.01). The expression of Arg-1 in HCC was related to differentiation degree (F=10.41, 30.03; all P<0.01). And with tumor differentiation decreased, the expression level down-regulated. Immunohistochemistry revealed that Arg-1 protein was mainly located in the cytoplasm and nuclear. The expression rates of Arg-1 were 88%, 98.7%and 100%in HCC, paracancerous tissues and normal liver tissues, respectively. Statistical analysis revealed that Arg-1 protein staining rate was signiifcantly lower in tumor tissues than that in paracancerous tissues (χ2=14.7416, P<0.01) and normal liver tissues (χ2=4.1415, P<0.05). The Arg-1 expression was correlated with differentiation degree of HCC, vascular invasion and recurrence after operation (χ2=22.8459, 10.2639, 10.6368 respectively;all P<0.05), but not correlated with age, gender, the hepatitis B virus, the level of serum AFP, liver cirrhosis, diameter of tumor and tumor number. Conclusion:The expression level of Arg-1 is much lower in HCC than that in the paracancerous liver and normal liver. Moreover, Arg-1 expression level is closely related to tumor differentiation degree, metastasis and relapse. These data demonstrate that Arg-1 may play a negative role in the development of HCC.

OBJECTIVETo investigate the effect of salidroside on hypoxia-induced apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) in rats.
METHODSRat CCSMCs were cultured in vitro by the enzyme digestion method and identified by immunofluorescent staining of anti-alpha-SMA and anti-Desmin. The non-toxic dose of salidroside was determined by MTT assay. Low-oxygen mixed gas (1% O2, 5% CO2, and 94% N2) was piped into a modular incubator chamber to induce hypoxia. The CCSMCs were divided into a normal, a hypoxia, and a 32 microg/mL salidroside intervention group. The apoptosis of the CCSMCs was detected by flow cytometry and the expression of the caspase-3 protein determined by Western blot.
RESULTSThe majority of the CCSMCs were positive for alpha-SMA and Desmin at immunofluorescent staining. Salidroside at < 32 microg/ml produced no obvious toxicity to CCSMCs. Compared with the normal control group, the rates of early and late apoptosis of CCSMCs were both increased significantly in the hypoxia group ([12.77 +/-1.41]% vs [18.69 +/- 1.29]%, P < 0.01 and [14.63 +/- 2.00]% vs [21.03 +/- 1.530]% , P < 0.05). Western blot showed a markedly increased expression of cleaved caspase-3 (P < 0.01). Intervention with 32 microg/ml salidroside significantly reduced hypoxia-induced early apoptosis of CCSMCs ([13.46% +/- 1.87]%, P < 0.01) and decreased the expression of cleaved caspase-3 (P < 0.01).
CONCLUSIONSalidroside can reduce the expression of cleaved caspase-3 and inhibit hypoxia-induced apoptosis of CCSMCs in rats.

The purpose of this study is to explore the feasibility of wheat germ agglutinin (WGA) modified liposome as a vehicle for ophthalmic administration. Liposome loaded with 5-carboxyfluorescein (FAM) was prepared by lipid film hydration method. WGA was thiolated and then conjugated to the surface of the liposome via polyethylene glycol linker to constitute the WGA-modified and FAM-loaded liposome (WGA-LS/FAM). The amount of thiol groups on each WGA molecule was determined, and the bioactivity of WGA was estimated after it was modified to the surface of liposome. The physical and chemical features of the WGA-modified liposome were characterized and the ocular bioadhesive performance was evaluated in rats. The result showed that each thiolated WGA molecule was conjugated with 1.32 thiol groups. WGA-LS/FAM had a mean size of (97.40 +/- 1.39) nm, with a polydispersity index of 0.23 +/- 0.01. The entrapment efficacy of FAM was about (2.95 +/- 0.21)%, and only 4% of FAM leaked out of the liposome in 24 h. Erythrocyte agglutination test indicated that after modification WGA preserved the binding activity to glycoprotein. The in vivo ocular elimination of WGA-LS/FAM fitted first-order kinetics, and the elimination rate was significantly slower than that of the unmodified liposome, demonstrating WGA-modified liposome is bioadhesive and suitable for ophthalmic administration.
