Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

Objective To evaluate the molluscicidal effect of niclosamide ethanolamine salt clustable powder (DP). Methods A comparative molluscicidal experiment was carried out by spraying method with niclosamide ethanolamine salt 4% DP. The experiments were respectively done in the labatory and field. The spraying with niclosamide ethanolamine salt 50% wettable power (WP) was used as the control. Results The molluscicidal effects of niclosamide ethanolamine salt 4% DP and 50% WP were similar in the laboratory. In the field, the effect of niclosamide ethanolamine salt 4% DP was lower than that of 50% WP in 3 d. However, the molluscicidal effects of the two formulations had not significant difference after 7 d. Conclusion The molluscicidal effects of niclosamide ethanolamine salt 4% DP and 50% WP were almost the same. DP is suitable for some areas where water are lack, or the water level are difficult to control.

Objective To observe the clinical efficacy of Tiao Shen Jie Jing needling (regulating the mind and release spasm) in treating post-stroke upper-limb spastic palsy. Method Ninety patients with post-stroke upper-limb spastic palsy were randomized into an observation group and a control group, 45 cases each. The observation group was intervened by Tiao Shen Jie Jing needling, while the control group was given ordinary acupuncture. The Modified Ashworth Scale (MAS), short-form Fugl-Meyer Assessment (SFMA) and Barthel Index (BI) were evaluated and recorded prior to the treatment, after 2-week and 4-week treatment and 3 months later after the intervention; the serumγ-aminobutyric acid (GABA) was detected before and after the treatment. Result The total effective rate was 83.3% in the observation group versus 61.0% in the control group, and the efficacy of the observation group was superior to that of the control group (P<0.05). The scores of each scale showed improvements after the treatment in both groups (P<0.05), and the improvements in the observation group were more significant (P < 0.05). The follow-up showed continuing improvements in the scales in the observation group, which were superior to those in the control group (P<0.05); after the treatment, the content of GABA in the observation group was significantly higher than that in the control group (P<0.05). Conclusion Tiao Shen Jie Jing needling can effectively ameliorate the upper-limb spasm,as well as the motor function of the upper extremities, improve the activities of daily living and maintain a long-term efficacy, better than ordinary acupuncture. The action mechanism is related to the regulation of GABA content in serum.

OBJECTIVETo demonstrate the effects and mechanisms of Huangkui capsule (HKC) on renal fibrosis in rats with diabetic nephropathy (DN).

METHODRats were randomly divided into 5 groups, the sham-operated group (Sham group, n = 5), the vehicle-given group (Vehicle group, n = 7), the low dose of HKC-treated group (L-HKC group, n = 7), the high dose of HKC-treated group (H-HKC group, n = 7) and the lipoic acid (LA)-treated group (LA group, n = 7). DN models were induced by intraperitoneal injection of streptozotocin (STZ,35 mg x kg(-1)) twice and unilateral nephrectomy. After models were successfully established, the rats in HKC and LA groups were daily administrated with HKC suspensions (0.75, 2 g x kg(-1)) or LA suspensions (60 mg x kg(-1)) respectively, and at the same time, the rats in Vehicle group were daily administrated with distilled water (2 mL) for 8 weeks. All rats were sacrificed at the end of week 8 to collect blood and renal tissues. UAlb, renal function, renal fibrotic morphologic characteristics, as well as oxidative stress (OS)-related markers, the protein expressions of the key signaling molecules in p38 mitogen-activated protein kinase (p38MAPK) signaling pathway, fibrogenic cytokines and inflammatory factors were examined respectively.

RESULTHKC, similar to LA, improved the general state of health, body weight, UAlb, BUN, UA and Alb in DN model rats. Of note, renal fibrosis was ameliorated in HKC groups,especially in H-HKC group which was better than that in LA group. In addition, HKC not only improved the main indexes of OS in the kidney like LA, but also down-regulated the protein expressions of phosphorylated-p38MAPK (p-p38MAPK), transforming growth factor (TGF)-β1 and tumor necrosis factor(TNF)-α in the kidney, whereas, LA only decreased the protein expression of TNF-α in the kidney in DN model rats.

CONCLUSIONHKC, similar to LA, has the actions of anti-OS in vivo. Moreover, HKC could attenuate renal fibrosis by suppressing the activation of p38MAPK signaling pathway and the protein expressions of fibrogenic cytokines and inflammatory factors in the kidney in DN model rats, which is different from LA.

OBJECTIVETo explore the effects and mechanisms of multi-glycoside of Tripterygium wilfordii (GTW) on improving glomerular inflammatory lesion in rats with diabetic nephropathy (DN).

METHODDN model was induced by unilateral nephrectomy and intraperitoneal injection of STZ (35 mg x kg(-1)) twice. The rats were randomly divided into 3 groups, the sham-operated group (Sham group, n = 5), the vehicle-given group (Vehicle group, n = 5 ) and GTW-treated group (GTW group, n = 5). After the model was successfully established, the rats in GTW group were daily oral administrated with GTW suspension (50 mg x kg(-1) x d(-1)), meanwhile, the rats in Vehicle group were daily oral administrated with distilled water (2 mL) for 8 weeks. From the beginning of the administration, all rats were killed 8 weeks later. Blood and renal tissues were collected,and then UAlb, renal function, glomerular morphology characteristics and glomerular macrophages (ED1 + cells) infiltration, as well as the protein expressions of inflammatory cytokines including tumor necrosis factor(TNF)-α and interleukin(IL)-lβ, and the key molecules in p38MAPK signaling pathway including p38 mitogenactivated protein kinase (MAPK), phosphorylated p38 (p-p38MAPK) and transforming growth factor(TGF)-β1 were investigated respectively.

RESULTGTW not only ameliorated the general state of health and body weight,but also attenuated UAlb, glomerulosclerosis, the infiltration of glomerular ED1 + cells and the protein expressions of TNF-α, IL-1β, p-p38MAPK and TGF-β1 in the kidney in DN model rats.

CONCLUSIONBy means of DN model rats, we demonstrated that GTW has the protective effect on renal inflammatory damage in vivo via inhibiting inflammatory cells infiltration and inflammatory cytokines expression. Furthermore, GTW could improve renal inflammatory lesion through down-regulating the expressions of the key signaling molecules in p38MAPK pathway such as p-p38MAPK and TGF-β1 ,and inhibiting the activation of p38MAPK signaling in the kidney.
