Parkinson′s disease(PD)is a common disease caused by multiple factors and characterized by pathological degen?eration in the dopaminergic neural system. Based on its pathogenic factors,PD can be divided into several subtypes,so it is essential to develop therapeutic agents based on the main pathogenic factor of each subtype of PD. Recently it is confirmed that the mutation of leucine-rich repeat kinase 2(LRRK2)gene leads to increased activity of the LRRK2 notably,and then causes neurodegeneration. Thus developing LRRK2 inhibitors to modulate the kinase activity will be a novel therapy for the PD subtype which is caused by LRRK2 gene mutation. LRRK2,either a kinase or a GTPase,has two drug binding sites. Therefore,two types of LRRK2 inhibitors are being studied,one is the kinase inhibitor and the other is GTPase inhibitor. This paper summarizes the recent progress in the dis?covery and development of LRRK2 inhibitors.

OBJECTIVE:To study the improvement effects of polydatin on renal fibrosis in rats and its mechanism. METH-ODS:50 rats was were randomly divided into sham operation group,model group,positive group(benazepril,5 mg/kg)and poly-datin high-dose and low-dose groups(100,50 mg/kg),with 10 rats in each group. Except for sham operation group,renal fibrosis model was induced by unilateral ureter obstruction. After modeling,administration groups were given relevant medicine intragastri-cally,and sham operation group and model group were given 0.5%sodium carboxymethyl cellulose solution once a day for consec-utive 4 weeks. The pathological change of renal tissue was scored. 24 h urinary protein and serum levels of urea nitrogen and creati-nine were determined,and the content of hydroxyproline,mRAN expression of TGF-β1 and FN were detected in renal tissue. RE-SULTS:Compared with sham operation group,pathological score,24 h urinary protein,serum levels of urea nitrogen and creati-nine,the content of hydroxyproline in renal tissue,mRNA expression of TGF-β1 and FN were all increased significantly (P<0.01). Compared with model group,24 h urinary protein,serum levels of urea nitrogen and creatinine and mRNA expression of FN in renal tissue decreased significantly in administation groups;the pathology scores,the content of hydroxyproline in renal tis-sue and mRNA expression of TGF-β1 of positive group and polydatin high-dose group were all decreased significantly(P<0.05 or P<0.01). CONCLUSIONS:Polydatin can prevent kidney fibrosis induced by unilateral ureteral obstruction,the mechanism of which may be associated with the mRNA expression down-regulation of TGF-β1 and FN in renal tissue.

267 newly-diagnosed patients with type 2 diabetes were divided into normoalbuminuria group [group N-UAlb, urinary albumin to creatinine ratio (UACR)<30 mg/g, n=103], microalbuminuria group(group M-UAlb, UACR 30~300 mg/g, n=88 ) , and macroalbuminuria group ( group L-UAlb, UACR>300 mg/g, n=76). The control group(group NC) consisted of 114 healthy individuals. Serum betatrophin, adiponectin(APN), and interleukin-1β( IL-1β) levels were determined with ELISA methods and the parameters of body mass index (BMI), estimated glomerular filtration rate(eGFR), HbA1C, fasting plasma glucose(FPG), OGTT 2h plasma glucose(2hPG), fasting insulin(FINS), OGTT 2h postprandial insulin(2hPINS), fasting C-peptide(FCP), homeostasis model assessment insulin resistant index(HOMA-IR), and blood lipid were collected. Compared with group NC, the serum betatrophin levels in patients with type 2 diabetes were obviously increased. In patients with type 2 diabetes, betatrophin levels increased along with the increase of UACR and there were significant differences in betatrophin among the three groups(P<0. 01). Betatrophin positively correlated with UACR, HbA1C, FPG, 2hPG, FINS, 2hPINS, HOMA-IR, TC, LDL-C, and TG( r were 0. 785, 0. 225, 0. 136, 0. 241, 0. 386, 0. 223, 0. 411, 0.216,0.193,and0.298,allP<0.05),and betatrophin were also positively correlated with APN and IL-1β(rwere 0. 643 and 0. 710, both P<0. 01). Stepwise multiple regression analysis showed that UACR, HbA1C, FINS, and TG were independent relevant factors affecting betatrophin levels.

Objective To investigate the expression levels of serum vasohibin-1(VASH-1)in type 2 diabetes mellitus(T2DM)patients at different stages of urinary albumin to creatinineratio(UACR)and to attempt to investigate the relationship between VASH-1 and inflammation and fibrosis in the pathogenesis of diabetic nephropathy(DN), one of the microvascular complications of T2DM. Methods 486 patients with T2DMwere divided into four groups:normal albuminuria [ UACR<30 mg/ g, n = 134], microalbuminuria [ UACR at 30-300 mg/ g, n = 122], clinical albuminuria [UACR > 300 mg/ g, n = 106 ], and clinical albuminuria hypertensive [ UACR > 300 mg/ g, with hypertension, n=124] groups. Age, course, serum levels ofVASH1, inflammation markers(CRP, ESR)and fibrosis marker( TGF-β1) with other biochemical indicators were measured, and 130 normal control subjects were also included. Results Compared with normal control group, the levels of UACR, HbA1C ,ESR, CRP, TGF-β1 and VASH-1 in groups ofnormal albuminuria, microalbuminuria, clinical albuminuria, and clinical albuminuria hypertensive were significantly higher(P<0. 05). Pearson correlation analysis showed that levels of VASH-1 were positively correlated with UACR, HbA1C ,ESR, CRPand TGF-β1( r = 0. 521, 0. 261, 0. 519, 0. 523, 0. 479, P<0. 001), while multivariate regression analysis showed that levels of UACR, HbA1C ,ESR, CRP and TGF-β1 were important factors affecting serum VASH-1 levels. Conclusion Serum levels of VASH-1 may become new biomarkers of early diagnosis of DN. Consequently, VASH-1 level may provide a new pattern and direction of inflammation and fibrosis for consideration in diabetic kidney damage.

In this study, 17 kinds of Dendrobium species of Fengdous including 39 individuals were collected from 4 provinces. Mitochondrial gene sequences co I, nad 5, nad 1-intron 2 and chloroplast gene sequences rbcL, matK amd psbA-trnH were amplified from these materials, as well as nrDNA ITS. Furthermore, suitable sequences for identification of Dendrobium species of Fengdous were screened by K-2-P and P-distance. The results showed that during the mentioned 7 sequences, nrDNA ITS, nad 1-intron 2 and psbA-trnH which had a high degree of variability could be used to identify Dendrobium species of Fengdous. However, single fragment could not be used to distinguish D. moniliforme and D. huoshanense. Moreover, compared to other combined fragments, new type combined fragments nrDNA ITS+nad 1-intron 2 was more effective in identifying the original plants of Dendrobium species and could be used to identify D. huoshanense and D. moniliforme. Besides, according to the UPGMA tree constructed with nrDNA ITS+nad 1-intron 2, 3 inspected Dendrobium plants were identified as D. huoshanense, D. moniliforme and D. officinale, respectively. This study identified Dendrobium species of Fengdous by combined fragments nrDNA ITS+nad 1-intron 2 for the first time, which provided a more effective basis for identification of Dendrobium species. And this study will be helpful for regulating the market of Fengdous.
