Objective To observe the clinical efficacy of Zishen Pingchan Granules in treating non-motor symptoms (NMS) of Parkinson disease (PD). Methods A randomized, double-blind, placebo-controlled trial was used. 124 patients with PD were randomly divided into the treatment group (n=62) and the control group (n=62). Patients not yet taking Western medicine were suspended the application of Western medicine, receiving direct TCM treatment. Patients who had already taken Western medicine were added TCM on the basis of original medicine dosage and method. The treatment group was given Zishen Pingchan Granules, while the control group was treated with placebo granule, once a bag, twice a day. The treatment lasted for 12 weeks. The clinical efficacy was assessed by using unified PD rating scale (UPDRSⅡ–Ⅲ), the scale for outcomes in PD for autonomic symptoms (SCOPA-AUT), Parkinson disease sleep scale (PDSS) and dosage of levodopa. Results The UPDRSⅡ and UPDRS Ⅲscores of the treatment group and the control group after 4, 8, and 12 week of treatment had no difference at each time point compared with before treatment (P>0.05). There was no statistical significance in scores of UPDRSⅡ and UPDRSⅢ after treatment (P>0.05). Efficacy of SCOPA-AUT in treatment group after treatment was significantly better than the control group; There was statistical significance in constipation, salivation, nocturia and sweating in SCOPA-AUT between the two groups after treatment (P<0.05). Compared with before treatment, PDSS scores in treatment group after 8 and 12 weeks of treatment increased significantly (P<0.05). After 4, 8, and 12 weeks of treatment, PDSS scores in treatment group were much higher than control group (P<0.01). By comparing PDSS score in the two groups before and after treatment, it showed that treatment group had better efficacy in extending the time to sleep, reducing nocturia, nightmares, and hallucinations (P<0.05). After 12 weeks of treatment, dosage of levodopa in control group increased significantly, which treatment group was much lower than the control group (P<0.05). Conclusion Zishen Pingchan Granules can improve the autonomic dysfunctionin and sleep quality of PD patients, and can significantly reduce the dosage of levodopa.

OBJECTIVETo investigate the protective effect and mechanism of baicalin on nerve tissue in rat with intracerebral hemorrhage (ICH).

METHODSRats were randomly divided into five groups: the sham-operated group, the ICH model group, and the three baicalin treated groups treated respectively with small, medium and large doses of baicalin. ICH rat model was established by injecting collagenase VII into caudate nucleus. Baicalin was given by peritoneal injection to the baicalin treated groups, and saline was given to the other two groups once a day started from 2 h after modeling. Animals were sacrificed in batches on the 1st, 3rd, 5th and 10th day of treatment to take their brains for detecting protease-activated receptor-1 (PAR-1) expression and cell apoptosis in brain tissue surrounding hematoma by Western blot and TUNEL method, respectively. And the water content of brain was estimated by dry-wet weight method.

RESULTSCompared with the model group, the PAR-1 expression and TUNEL-positive cells were significantly reduced in the baicalin treated groups; and brain edema was also significantly reduced (P<0.01).

CONCLUSIONSThe up-regulated PAR-1 expression after ICH in rats might play an important role in inducing cell apoptosis and brain edema. Baicalin shows significant protective effect on ICH rats, which may be related to its effects in inhibiting PAR-1 expression and decreasing apoptosis cells, so as to reduce brain edema.

Objective To investigate the role of inflammatory cytokines in the pathogenesis of chronic non-bacterial prostatitis/chronic pelvic pain syndrome (CAP/CPPS) patients. Methods The 38 cases with CAP/CPPS patients (18 cases of CAP and 20 cases of CPPS) and 20 cases of healthy controls were selected. The differential expressions of 40 kinds of inflammatory cytokines were detec-ted by antibody arrays in prostate fluid. Results The inflammatory cytokines which increased more than 1.5 times expression have been found. There were seven kinds in CAP including monocyte che-moattractant protein (MCP)-1, solution tumor necrosis factor receptor Ⅱ(s TNF R Ⅱ), platelet-de-rived growth faetor-BB (PDGF-BB), interleukin (IL)-β, IL-11、IL-6、MCP-2 and five kinds in CPPS groups including MCP-1、PDGF-BB、MCP-2、s TNF R Ⅱ、It-11 respectively, compared with healthy control group. The cluster analysis results showed that protein expression of Monocyte chemoattrac-tant protein 1 (MCP-1)and platelet-derived growth factor BB (PDGF-BB) were significantly increased in CAP (3.47 and 2.07 times) and CPPS (2.25 and 2.19 times) compared with healthy control group and were the final polymerization of inflammatory cytokines. The protein expression of interleukin 1 β (IL-1 β), MCP-1 and soluble tumor necrosis factor Ⅱ (s TNF R Ⅱ) in CAP group was increased more than 1.85,1.55,1.67 times compared with CPPS group. Conclusions Elevated expression of inflammatory cytokines may play an important role in the course of CAP/CPPS disease. The extent of the inflammatory response of CAP was higher than CPPS. The inflammatory factors of MCP-1 and PDGF-BB could serve as a novel diagnostic marker.

Objective To screen the Chinese drugs with liver channel tropism acting on the characteristic differential expressed protein of human liver cancer cell protein tyrosine kinase (PTKs) system by protein chip technology, and to analyze the difference in different Chinese drugs with liver channel tropism in relation to PTKs regulation. Methods Forty BALB/C nude mice were chosen; a piece of subcutaneous tumor mass was implanted into the left lobe of liver parenchyma to reduplicate the orthotopically implanted tumor models. After modeling for 10 days, the tumorigenicity was confirmed, and all the nude mice models were divided into four groups; different Chinese medicine extracts were injected intra-peritoneally into corresponding treatment groups respectively, and the methods of treatment in the 4 groups were as follows: In liver channel tropism drug pair of Huayu Xiaozhen group, rhizoma sparganii and curcuma zedoary with dosage containing crude drug 4.5 g·kg-1·d-1 was given, in liver channel tropism drug pair of Gongdu Sanjie group, the extract of centipede and scorpion with dosage containing crude drug 0.3 g·kg-1·d-1 was intra-peritoneally injected, in spleen channel tropism drug pair control group, astragalus and rhizoma atractylodis macrocephalae with dosage containing crude drug 6.3 g·kg-1·d-1 was given, and in the model group, equal amount of 0.9% normal saline was intra-peritoneally injected. After the drug treatment for 3 weeks, the mice were sacrificed and the liver cancer tissue was obtained; after its total protein was extracted, protein chip technology was applied to screen the Chinese drug pair with liver channel tropism acting on differential expressed PTKs of human liver cancer cells, and the results were analyzed by cluster analysis.Results After the end of the experiment, there were 6 animals in Huayu Xiaozhen drug pair group, 5 in Gongdu Sanjie drug pair group, 5 in control drug pair group and 7 in model group. The protein chip screening results showed that the adjusting fold greater > 1.50 or < 0.67 was defined as the difference with statistical significance. Compared with model group, there were 42 up-regulated expressions of PTKs in Huayu Xiaozhen drug pair group, including 29 receptor tyrosine kinases (RTKs) and 13 non-receptor protein tyrosine kinases (nrPTKs) of which the erythropoietin having adjusting fold over 5.0 produced liver cell receptor B1 (EphB1), epidermal growth factor receptor (ErbB2, ErbB4) etc. 3 RTKs; there were 7 RTKs with adjusting fold 3.0 - 5.0 including EphA1, EphA3, EphA7, fibroblast growth factor receptor 2-α (FGFR2-α), hepatocyte growth factor receptor (HGFR), macrophage colony-stimulating factor receptor (M-CSFR) and vascular endothelial growth factor receptor 2 (VEGFR2), and 2 nrPTKs with adjusting fold 3.0 - 5.0 were non-receptor tyrosine kinase BMX (BMX) and Janus kinase 1 (JAK1). In the Gongdu sanjie drug pair group, there were 23 up-regulated expressions: 15 RTKs and 8 nrPTKs, and 6 down-regulated expressions; the RTKs with adjusting fold 3.0 - 5.0 were ErbB4, M-CSFR and 1 nrPTKs that was megakaryocyte-associated tyrosine kinase (MATK). In the control drug pair group, there were 28 up-regulated and 8 down-regulated expressions. The results of cluster analysis showed that in Huayu Xiaozhen drug pair group, there were 17 differential expressed PTKs in accord with the screen criteria of which 9 were RTKs [receptor tyrosine kinase-like orphan receptor 2 (ROR2), stem cell factor receptor (SCFR), anaplasia lymphoma kinase (ALK), platelet-derived growth factor receptor β (PDGFR-β), insulin-like growth factor-IR receptor (IGF-IR), ErbB2, ErbB3, EphB1 and EphA2], 1 nrPTKs [fps/fes related tyrosine kinase (FER)] and 7 PTKs 3 RTKs (M-CSFR, FGFR2-α, EphA3) and 4 nrPTKs [acetate kinase 1 (ACK1), bruton tyrosine kinase (Btk), non-receptor tyrosine kinase ABL1 (ABL1) and BMX]. In Gongdu Sanjie drug pair group, there were 7 differential expressed PTKs in accord with the screen criteria 5 RTKs (M-CSFR, FGFR1, ROR2, EphB1, ErbB2) and 2 nrPTKs [src-related kinase lacking C-terminal regulation and N-terminal myristylation sites (SRMS), FER]. Conclusions The drug pair of centipede and scorpion with Gongdu Sanjie action possesses a more effective anti-HCC role than the drug pair of rhizoma sparganii and curcuma zedoary with Huayu Xiaozhen action, the mechanism is possibly via the regulation of PTKs signal pathway. The liver channel tropism drug pair of rhizoma sparganii and curcuma with action of promoting blood circulation and removing blood stasis possibly has an independent anti-HCC effective pathway outside the PTKs signal system.
