To investigate the potential use of synthetic stabilized ribozymes for the treatment of chronic hepatitis C virus (HCV) infection,we designed and synthesized 2 hammerhead ribozymes (Rz213 and Rz498) targeting conserved sites in the 5′noncoding region (NCR) and C gene of HCV RNA.Constructed to the eukaryotic vector pcDNA3, the two ribozymes were respectively or simultaneously transfected with lipofectamine into WISHnc transgenic cells, which could express permanently HCV C luciferase protein under the control of HCV 5′NCR.The expression of C luciferase was measured by luminometer.The results showed that the luciferase activities were significantly down regulated in the WISHnc cells, and the inhibitory rates were 42.94%～67.81% within 7 days after ribozymes transfection. There was no significant differences between Rz213 or Rz498 and co transfection, but adding the target site of ribozymes might prevent host cells from the loss of ribozyme therapeutic effect due to viral gene mutation.

Objective To observe the clinical curative effect of combination of traditional Chinese and western medicine for treatment of patients with hepatitis B virus (HBV) related acute-on-chronic (subacute) liver failure (ACLF). Methods A prospective randomized controlled trial was conducted; 66 cases of HBV-ACLF patients were randomly divided into two groups: a test group (44 cases) and a control group (22 cases). Conventional western medicine treatment was given to both groups; the patients in test group additionally received the traditional Chinese medicine (TCM) in accord to the principles of differentiation of syndromes in TCM, in cases with damp-heat and blood stasis syndrome with yellow appearance, Liangxue Jiedu Huayu decoction (Paeoniae Radix Rubra 60 - 150 g, Artemisiae Scopariae Herba 30 - 90 g, Gardeniae Fructus 9 - 12 g, Hedyotis diffusa Willd 20 - 30 g, Salviae Miltiorrhizae Radix et Rhizoma 30 g, Atractylodis Macrocephalae Rhizoma 30 g, Rubiae Radix et Rhizoma 30 - 45 g, Siegesbeckiae Herba 30 - 45 g, Bletillae Rhizoma 15 g ) was given, in cases with Qi deficiency and blood stasis with yellow appearance, Yiqi Jiedu Huayu decoction (Astragali Radix Preparata Cum Melle 30 g, Pseudostellariae Radix 15 g, Artemisiae Scopariae Herba 30 - 60 g, Polygoni Cuspidati Rhizoma et Radix 15 - 30 g, Salviae Miltiorrhizae Radix et Rhizoma 30 g, Aconiti Lateralis Radix Preparata 10 - 15 g, Atractylodis Macrocephalae Rhizoma 30 g, Rubiae Radix et Rhizoma 30 - 45 g, Siegesbeckiae Herba 30 - 45 g, Gigeriae Galli Endothelium Corneum 20 g) was given, the dosage in both groups being 1 dose daily, one dose was prepared to a water decoction 250 - 300 mL which was divided into two parts, one part taken twice a day; the control group received only western medicine treatment. After 2 weeks of treatment, the clinical comprehensive curative effect, the syndrome score efficacy, and the changes of main indexes of liver function,cholinesterase (ChE), albumin (Alb), prothrombin activity (PTA) were observed in the two groups.Results The clinical total efficacy in the test group was significantly higher than that in the control group [75.0% (33/44) vs. 45.5% (10/22),P < 0.05]. The syndrome score total efficacy in the test group was also higher than that in the control group [75.0% (33/44) vs. 63.6% (14/22)], but the difference was not statistically significant (P > 0.05).

Objective To investigate the effects of resistin on mesangial cells proliferation induced by high glucose and subsequent change of p38MAPK signal pathway. Methods Human macrophrages were cultured and treated with adenovirus encoding for resistin (Ad-resistin) for 48 h and were then co-cultured with human mesangial cells stimulated by high glucose for another 48 h. Mesangial ceils were harvested and their proliferation was measured by 3H-TdR. Activator protein 1 (AP-1) was examined by immunocytochemistry and laminin of excellular matrix was observed with immuofluorescence. Protein levels of p38MAPK and TGF-β1 were measured by Western blot. Smad2 phosphatase activity was aslo detected by Western blot. Results The mRNA and protein levels of resistin were significantly higher in Ad-resistin treated macrophages than those in Ad treated cells (P<0.01). Over-expression of resistin up-regulated p38MAPK protein levels of human mesangial cells(P<0.05). Resistin also promoted the proliferation of mesangial cells (P<0.01) and the synthesis of laminin stimulated by high glucose. The expression of TGF-β1 and phosphorylation of Smad2 were up-regulated in the mesangial cells (P< 0.05). Conclusion Macrophage cytokine resistin may promote mesangial cells proliferation and abnormal accumulation of excellular matrix stimulated by high glucose via activating p38MAPK signal passway.

The acute iv and ig LD50 of sudoxicam synthesized by Shanyan Ph-armaceutic College was calculated to be 135?10. 7 and 320 ? 96 mg/kg in mice. In polyarthritic rats, Sud at 2 and 4 mg/kg/d for 28 days did not induce changes in serum AKP, SGPT, BUN the morphal-ogic characteristics of the gastrointestinal tract, liver and kidney. In 3 dogs orally given Sud 16 mg/kg/d for 5 consecutive days, 2/3 died at days 10 to 13. In other 3 dogs given Sud 16 mg/kg/d every other day, plasma concentrations of Sud were determined by ultra violet spectrophotometry. It was found that on the days 10 to 20 , the concentration time curves had attained a intoxicant steady state with plasma sudoxicam concentrations as high as 44. 9 ? 73. 9?g/ml ,and all of them died after 17~25 days. Their bleeding time and coagu- lation time were prolonged to 2 or 3 times of the control and serum BUN was increased. In one dog autopsy revealed the interstitial inflammation of the kidney and small local necrosis of the live, but not in other dogs.Gastric ulceration in rats can be produced by the oral administration of verious doses of Sud. The UD50 of Sud was 15.47mg/kg. It was found that the gastric ulceration in rats is related to the plasma levels

Objective:To evaluate the reliability and validity of a computerized cognitive assessment system designed for screening mild cognitive impairment (MCI), and compare the screening accuracy among constructed different machine learning classification models. Methods:A group of random stratified samples of over 55 years old residents in the communities, nursing homes and memory-clinics from Shanghai and Henan were selected to assess their cognitive status using Montreal Cognitive Assessment (MoCA) by well-trained investigators. The reliability and validity were assessed by intrinsic consistency analysis and factor analysis, respectively. Taking the results of MoCA as standards, four machine learning classification algorithms, i.e., naïve Bayesian classification model, random forest classifier, Logistic regression classifier, and K-nearest neighbor classifier, were compared in accuracy and area under curve (AUC). Results:A total of 359 participants were included, the median age of whom was 63 years old. And 82.80% of them were secondary school graduates or below. According to the results of MoCA, 147 of them might be MCI. The Cronbach's α and KMO of this system were 0.84 and 0.78, respectively; Bartlett's sphericity test was significant (P<0.05); thirteen common factors could explain 75.10% of the system. The best classification model was naïve Bayesian classification model, and its accuracy and AUC were 88.05% and 0.941, respectively. Conclusion:The new designed computerized cognitive assessment system has been proved to be reliable and valid. The naïve Bayesian classification model has good classification accuracy.

Objective To explore the mechanism of the low-frequency electrical stimulate on pedunculopontine nu-cleus to treat the Parkinson (PD) through observinge the low-frequency electrical stimulation of Pedunculopontine Nucleus (PPN) in PD rat model and the effects of neurotransmitters (GPi) neurons discharge in the medial part of the globus pallidus. Methods Thirty SD rats were randomly assigned to the control group and the PD model group, with 15 in each group. PD model was established through injecting 6-OHDA into Substantia nigra compact (SNc) of black rat. Effect of low frequency electrical stimulation, micro-electrophoresis glutamate (Glu) and its receptor blocking breaking agent MK-801,γ-aminobu-tyric acid (GABA) and its receptor antagonist bicuculline (BIC) on discharge of rat neuron GPi was examined using extracel-lular unit recording methods through seven glass microelectrode recording. Results When stimulated by low frequency electrical stimulation of PPN, reactions from the control group and neuronal response GPi in PD rats were inhibited. The aver-age discharge frequency was reduced compared to pre-stimulation (P < 0.01). Micro-electrophoresis and BIC Glu excite neurons while microiontophoresis MK-801 and GABA restrain neurons. In the background of micro-electrophoresis BIC’s excitatory effects on neuron, low-frequency electrical stimulation on PPN reduced neuronal firing frequency. And in the background of inhibition effect of micro-electrophoresis MK-801, low-frequency stimulation PPN further restrain neuronal discharge frequency. Conclusion Low frequency electrical stimulation inhibits GPi PPN neuronal activity probably though regulating neurons projecting to the Glu and GABA nerve pathways in GPi neuron.
