Acute myocardial infarction (AMI) is one of the most common cardiovascular diseases. The clinical pathway is the therapeutic program for disease-specific treatment and its implementation may reduce both the duration and cost of the hospital stay. This study aims to construct and evaluate the efficacy of clinical pathways (CPs) based on integrated traditional Chinese and Western medicine for patients with AMI.

Objective To observe the effect of Duanteng Yimu decoction (DYD) on bone turnover markers of C-terminal telopeptide of type Ⅰ collagen (CTX-Ⅰ) and N-terminal propeptide of type Ⅰ procollagen ( PⅠNP) of adjuvant-induced arthritis (AA) rats. Methods Seventy-two SD rats were divided into 9 groups, and complete Freund's adjuvant was injected into the rats to establish adjuvant-induced arthritis rat model. After medication for 36 days, the pedal swelling, the serum levels of CTX-Ⅰand PⅠNP, and ankle X-ray photographic scores were observed. Results The pedal swelling degrees and ankle X-ray scores in medication groups were lower than those in the model group ( P<0.05). The PⅠNP level had no statistically significance in various groups ( P>0.05). The CTX-Ⅰlevel in low-dose DYD group was decreased (P<0.05). Conclusion Caulis Celastri has two-way effects on CTX-Ⅰlevel of female AA rats, and its side effects can be reduced by Radix Dipsaci and Herba Leonuri, but their antagonism effect will disappear with the increase of the dose of Caulis Celastri.

Objective To establish heterologous expression system of Na+-glucose cotransporter 2 (SGLT2) gene.Methods Human SGLT2 cDNA from normal kidney, generated by RT-PCR,was subclonedintoPEXL-GFP vector andtransfectedinto HEK293cells. After 24hours of incubation, the expression of SGLT2-GFP fusion protein was detected by Western blotting and laser confocal microscopy.Transport activity of SGLT2-GFP fusion proteins in cultured human HEK293 cells was evaluated with the uptake test of glucose analogue.ResultsSGLT2-GFP fusion protein was expressed in cultured human HEK293 cells.Furthermore, confocal microscopy using green fluorescent protein(GFP) revealed a punctate membrane pattern of SGLT2.Glucose analogue uptake increased in HEK293 cells transfected with SGLT2-GFP at least by 3.5 folds compared with HEK293 cells transfected with GFP vector only(P＜0.01).Conclusion Heterologous expression of SGLT2 gene in HEK293 cells is successfully established, which provides valuable approach for the functional and pathological study of SGLT2 gene.

AIM: In this study,we tested the hypothesis that remote postconditioning induced by a single 5-min episode of femoral artery occlusion and reperfusion applied immediately before the onset of coronary artery reperfusion protects the myocardium from reperfusion injury.METHODS: Thirty healthy New Zealand white rabbits were randomly divided into three groups(n=10 in each group): control,myocardial ischemic postconditioning(MIP) and Limb ischemic postconditioning(LIP).Myocardial infarct size and tissue myeloperoxidase(MPO) activity were determined at the end of the experiment.Plasma creatine kinase(CK) activity and malondialdehyde(MDA) levels were measured at baseline,the end of ischemia,and after 180 min of reperfusion,respectively.RESULTS: Myocardial infarct size was significantly reduced in MIP and LIP as compared to control(P

Objective:To define more information for familial hematuria by genetic screening in a pedigree with familial hematuria.Methods:This was a 4 generation pedigree included 20 family members. The clinical data and laboratory manifestations of the family members were reviewed and collected from medical records. Meanwhile, the peripheral blood samples of 11 family members of the pedigree were collected, and then DNA samples were extracted by salting out method for genetic analysis. For genetic analysis, firstly, three family members including the proband were selected for whole exome sequencing, and the genetic variations were screened according to the sequence variation interpretation guidelines from the American College of Medical Genetics and Genomics (ACMG) for diagnostic sequence interpretation. Then PCR and Sanger sequencing were used to verify the identified pathogenic variants in all family members in the pedigree.Results:In the pedigree, 6 female members had persistent hematuria. Among them, 2 died due to end-stage renal disease, 2 died due to non-renal diseases, and 2 maintained stable renal function. One of the two members with stable renal function was diagnosed as IgA nephropathy by renal biopsy. Moreover, diffuse basement membrane lesions were identified in her renal biopsy sample after the electron microscope examination, which resulted in the suspected diagnosis of Alport syndrome. Genetic testing in this pedigree revealed two novel mutations in COL4A4 gene (NM_000092), c.G446T:p.G149V in exon 7 and c.G1249A:p.G417R in exon 20. Conclusion:Two novel mutations of COL4A4 gene (c.G446T:p.G149V in exon 7 and c.G1249A:p.G417R in exon 20) in a hematuria pedigree are related with phenotype of familial hematuria.

Objective To evaluate the efficacy and safety of intravesical alkalised lidocaine therapy for the treatment of ketamine-associated cystitis. Methods From 2008 to 2009,7 cases of patients (6 males and 1 female; mean age 26 years) were admitted with severe lower urinary tract symptoms (LUTS). Three cases had painful hematuria. All cases had history of abuse ketamine. B ultrasound examination revealed marked thickness of the bladder wall and small bladder capacity. Urodynamic study were performed showing the functional bladder capacities between 20 to 100 ml(average 50 ml),Qmax between 3.7 to 10.8 ml/s, RUV between 0 to 24 ml. Urodynamic analyses showed hypersensitive bladder and decreased bladder compliance. Cystoscopy showed diffuse reddish swelling of the bladder mucosa and hemorrhagic cystitis. All patients were required to withdraw the ketamine and treated with bladder hydrodistention therapy (intravesical alkalised lidocaine with heparin). Results The biopsies of 2 patients showed bladder wall inflammation and fibrosis. LUTS was significantly relieved after bladder installation within 7 days. The functional bladder capacities increased between 150±30 ml,Qmax 11.5±3.8 ml/s. Four cases became asymptomatic. Three recurrent cases after reabused ketamin for 1 to 3 months received same intraversical treatment. All cases were followed up for 2 to 17 months. Conclusion Intravesical hydrodistention therapy with alkalised lidocaine and heparin could be the safe and effective therapy in the treatment of katamine-associated cystitis.

Pharmaceutical standard system which belongs to an important part of national drug policies is an inevitable result of the development of pharmacy. There was a long standing of pharmaceutical standard system in China whose germination could be traced back to Qin and Han dynasties, and it had laid a solid foundation for the establishment and improvement of modern pharmaceutical standard system by continual accumulation from the past dynasties. Since the founding of new China, distinguished achievements had been obtained on pharmaceutical standardization working,and currently it is in a new developing stage. There was a brief description in this paper on the development history of pharmaceutical standard system in China.

Agitation plays an important role in the hyaluronic acid (HA) fermentation process. However, views about the effect of agitation on HA production remain controversial. We investigated the effect of agitation on cell growth and HA synthesis during HA fermentation process by using Computational Fluid Dynamics (CFD) technology. The results showed that the biomass and HA yield changed a little with the increase of impeller speed, but the HA molecular weight firstly increased and then decreased. The results of phase agitation control strategy demonstrated that the influence of agitation on the HA molecular weight mainly exhibited at the stage of HA synthesis. Moreover, the CFD simulation results indicated that when impeller speed increased, the mixing time reduced while the shear rate increased significantly. The removal of anchor could moderate the contradiction between the mixing time and shear rate, and finally the HA molecular weight increased by 23.9%. The results of this work could provide guidelines for optimizing the HA fermentation, as well as the bioreactor design and scaling up.

Background: Maedi/Visna virus (MVV) is a contagious viral pathogen that causes considerable economic losses to the sheep industry worldwide. Objectives: In China, MVV has been detected in several regions, but its molecular characteristics and genetic variations were not thoroughly investigated. Methods: Therefore, in this study, we conducted next-generation sequencing on an MVV strain obtained from northwest China to reveal its genetic evolution via phylogenetic analysis. Results: A MVV strain obtained from Inner Mongolia (NM) of China was identified. Sequence analysis indicated that its whole-genome length is 9193 bp. Homology comparison of nucleotides between the NM strain and reference strains showed that the sequence homology of gag and env were 77.1%–86.8% and 67.7%–75.5%, respectively. Phylogenetic analysis revealed that the NM strain was closely related to the reference strains isolated from America, which belong to the A2 type. Notably, there were 5 amino acid insertions in variable region 4 and a highly variable motif at the C-terminal of the surface glycoprotein (SU5). Conclusions The present study is the first to show the whole-genome sequence of an MVV obtained from China. The detailed analyses provide essential information for understanding the genetic characteristics of MVV, and the results enrich the MVV library.
