Objective To evaluate the distribution of non-motor symptoms(NMS) and dominant factors impacting on the prevalence of NMS in Parkinson's disease(PD). Methods The NMS questionnaire(NMSQuest) was administered to 128 patients(PD group) and 128 healthy adults(control group).The distribution of items of NMS was analyzed between the two groups,and clinical characteristics were also collected to assess the dominant factors impacting on the prevalence of NMS. Results There were significant differences in the prevalence of NMS between the two groups(P

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Objective To investigate whether mesenchymal stem cells can promote the recovery of acute renal tubular damage induced by mercuric chloride and to explore its possible mechanism.Methods Acute renal failure rat model was established by intraperitoneal injection of mercuric chloride.SD rats were randomly divided into three groups which were MSCs injection group, saline infusion group and normal control group.Seven days later,the changes of rat weight,survival,renal function and pathology were observed;PCNA,ED-1 and GFP were detected by immunohistochemistry; The expression of cytokines in kidney and the distribution of GFP plasmid-transfected MSCs in kidney were examined by RT-PCR.Results MSCs infusion ameliorated the decline of rat weight,survival, renal function,and pathological changes.PCNA and ED-1 positive cells in MSCs group were fewer than those in saline group.Expression of growth factors EGF,PDGF,HGF were obviously up- regulated and pre-inflammatory cytokines TNF-?was significantly reduced in MSCs-treated kidneys. GFP-labelled MSCs occurred occasionally in renal interstitium of MSCs-treated rats,but not in renal tubules.Conclusions Bone marrow mesenchymal stem cells can promote the recovery of acute renal tubular epithelial cells damage caused by mercuric chloride.The mechanism may partly depend on regulating the excretion of cytokines in renal microenvironment rather than completely depend on their differentiation to tubular cells.

There are reports about the chemical compounds of Ciwujia herbs, but with no study report about the chemical material basis of Ciwujia injection (CWJI). In this study, LC-MS(n) and LC-Q-TOF-MS techniques were adopted for a qualitative analysis on phenylpropanoids in CWJI. The Ultmate XB-C18 column (4.6 mm x 250 mm, 5 microm) was adopted and eluted with the mobile phase of 0.5% formic acid-water and acetonitrile, with the flow rate at 0.8 mL x min(-1) and the column temperature at 20 degrees C. Based on the data of high-resolution and multi-stage MS, control products and literatures, altogether 54 phenylpropanoids were identified in Ciwujia Injection, including 34 phenylpropanoids, 16 ligans and 4 coumarins. Among them, 28 were reported for the first time in Ciwujia, and 14 compound structures were identified in comparison with the control products. The method established in this study could be used to simply and rapidly identify phenylpropanoids in CWJI. The findings provide scientific data for defining the chemical material basis of CWJI.

Objective: To observe the clinical efficacy difference in treating irritable bowel syndrome-diarrhea (IBS-D) of liver-qi stagnation and spleen-deficiency pattern with different treatment protocols, and the effects on serum levels of 5-hydroxytryptamine (5-HT), substance P (SP) and vasoactive intestinal peptide (VIP), for unveiling the mechanism of intradermal needle therapy plus pinaverium bromide in treating IBS-D. Methods: A total of 123 IBS-D patients were divided into an observation group, a Western medication group and an integrated Western and Chinese medication group using the random number table method, with 41 cases in each group. The Western medication group was given oral pinaverium bromide, 50 mg each time and 3 times a day. The integrated Western and Chinese medication group was given additional Chinese herbal medicine Tong Xie Yao Fang, one dose each day. The observation group was given additional intradermal needle therapy on the basis of the Western medication group. The whole intervention lasted for 6 weeks. Before and after treatment, the scores of gastrointestinal symptoms, traditional Chinese medicine (TCM) symptoms, irritable bowel syndrome (IBS) symptom severity scale (IBS-SSS) and IBS quality of life (IBS-QOL) questionnaire, as well as the serum levels of 5-HT, SP and VIP were observed. The clinical efficacy was estimated. Results: The total effective rate was 92.7％ in the observation group, 68.3％ in the Western medication group and 78.1％ in the integrated Western and Chinese medication group. The total effective rate was higher in the observation group than in the other two groups, and higher in the integrated Western and Chinese medication group than in the Western medication group, showing statistical significance (all P<0.05). After treatment, the scores of gastrointestinal symptoms, TCM symptoms and IBS-SSS showed significant decreases in the three groups, presenting statistical significance compared with the baseline (all P<0.05); the scores of gastrointestinal symptoms, TCM symptoms and IBS-SSS were notably lower in the observation group than in the other two groups (all P<0.05), and lower in the integrated Western and Chinese medication group than in the Western medication group (all P<0.05). After treatment, the eight component scores of IBS-QOL showed significant increases in the three groups compared with the baseline (all P<0.05); the eight component scores in IBS-QOL were significantly higher in the observation group than in the other two groups (all P<0.05), and higher in the integrated Western and Chinese medication group than in the Western medication group (all P<0.05). After treatment, the serum levels of 5-HT, SP and VIP decreased markedly in the three groups compared with the baseline (all P<0.05); the serum levels of 5-HT, SP and VIP were significantly lower in the observation group than in the other two groups (all P<0.05), and lower in the integrated Western and Chinese medication group than in the Western medication group (P<0.05). Conclusion: Treatment with intradermal needle therapy plus pinaverium bromide results in significant improvements in the gastrointestinal symptoms and quality of life in patients with IBS-D of liver-qi stagnation and spleen deficiency pattern, and effectively regulates the gastrointestinal hormone production.

OBJECTIVE: To test the technical parameters of GlobalFiler® PCR Amplification Kit for its application to forensic application value and to investigate the genetic polymorphisms. METHODS: The validation was conducted in sensitivity, mixed samples, species specificity, adaptability, survivability, consistency, peak height balance and stability. The amplification and detection of the genomic DNA from 373 unrelated individuals from Beijing Han nationality were extracted by automation workstation. RESULTS: Global-Filer® PCR Amplification Kit was adaptive to some mixed, degraded and inhibited samples. The power of sensitivity and adaptability and peak height balance showed well. The distributions of genotype frequencies for 21 STR loci in the population were all in accordance with Hardy-Weinberg equilibrium (P > 0.05). The PIC value of the 21 STR loci was among 0.536 to 0.940; the H value was among 0.558 to 0.933; the DP value was among 0.783 to 0.992; the PE value was among 0.243 to 0.874. CONCLUSION GlobalFiler® PCR Amplification Kit is suitable for criminal cases and DNA database in forensic practice. And 21 STR loci in Beijing Han nationality have high polymorphism, which have application value in forensic practice and population genetics.
