Using information on the Emergency Department of the Sino-Japanese Friendship Hospital-reconstructed in January of 2002-as primary data, the authors provide a general view of the model for the building, management and development of emergency departments in China in the 21" century. There are two aspects to the issue. One concerns the composition of the hardware architecture of the emergency department, including emergency medical service system(EMSS), modified layout and facilities, medico-technical departments with a complete range of functions, rational emergency medical service procedures as well as pie-hospital first aid and facilities for long-distance network medical treatment. The other concerns the composition of the software architecture of the emergency department, including the transformation of the employment system of emergency medical personnel, the change of emergency service concepts, the personnel performance and financial control of the emergency department, and the development of an emergency department culture.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

AIM: To investigate the effect of enhanced green fluorescence protein (EGFP) gene transfection on the cell cycle distribution of primary cultured human chondrocytes in order to establish a tracking method of cultured human nasoseptal chondrocytes. METHODS: pEGFP-N1 plasmid was amplified in E.coli, and purified by high purity kit. Primary cultured human chondrocytes,which were initially obtained from the nasoseptal cartilage, were cultured in vitro and transferred with pEGFP-N1 by means of electroporation with Amaxa nucleofector device. Transfering process and transient expression were evaluated by laser scanning confocal microscope (LSCM), the transfer efficiency and the cell cycle distribution were evaluated by flow cytometry. RESULTS: There was significant expression of EGFP at 24 h after transferring. The transfection efficiency of pEGFP-N1 into primary cultured human chondrocytes reached 35 37% at 48 h. It didn't affect the process of cell adherance and had no effect on the cell cycle distribution. CONCLUSION: Primary cultured human chondrocytes, which were transfected with pEGFP, are alive in vitro, and the transferring process doesn't affect the cell cycle distribution. These results suggest that pEGFP-N1 is an ideal transient expression vector for primary cultured human chondrocytes and it might be a well tracer in construction tissue engineered cartilage.

OBJECTIVETo investigate the effects of curcumin on the expressions of TNF-alpha, IL-6 and IL-8 in rats with chronic nonbacterial prostatitis.

METHODSSixty healthy adult male SD rats with the body weight of 200 -220 g were equally and randomly divided into a normal control, a positive control, a model, an oral curcumin and an intraperitoneal curcumin group. The rat models of chronic nonbacterial prostatitis were made by hypodermic injection of estradiol benzoate at the dose of 0.25 mg/(kg x d) for 30 days after castration, and then treated with curcumin at 200 mg/(kg x d) by gavage or intraperitoneal injection. The positive controls received oral celebrex at 250 mg/(kg x d), while the normal control and model groups were given saline by gavage. After a week of treatment, the levels of TNF-alpha, IL-6 and IL-8 in the serum and prostate tissues of the rats were detected by ELISA assay.

RESULTSThe levels of TNF-alpha and IL-8 in the serum and prostate tissues were significantly lower in the intraperitoneal curcumin than in the positive control group (P < 0.05), but the expression of IL-6 showed no significant difference between the two groups (P > 0.01).

CONCLUSIONCurcumin is efficacious for chronic nonbacterial prostatitis in rats, and the action mechanism may be associated with its decreasing effect on the proinflammatory cytokines IL-8 and TNF-alpha in the blood and tissues.

Results The efficacy rates were 84.6% and 29.0% for tacrolimus group and vehicle group, respectively (P

New Chemical Entities (NCEs) development is a systematic long-term project that involves multiple disciplines. The translation research will help to build an advanced R&D system from the basic laboratory research, preclinical studies and clinical evaluation to clinical application of drug, for the purpose of shortening the R&D cycle and accelerate the launch of new drugs. In new drug R&D and its clinical application, drug disposition (absorption, distribution, metabolism, excretion, ADME) properties are important criteria for assessing drug-likeness of candidates. ADME evaluation of NCEs plays an important role in the translation research throughout innovative drug R&D process. Therefore, ADME evaluation at the early stage of drug design and development will be helpful to improve the success rate and reduce costs, and further access to safe, effective drugs.

Objective:To investigate the pathogenic spectrum of hand, foot and mouth disease(HFMD)from 2017 to 2019 in Guangzhou, and analyze molecular epidemiological characteristics of coxsackievirus A6 (CV-A6).Methods:Enterovirus A71 (EV-A71), CV-A16, CV-A6 and enterovirus were tested by reverse transcription-quantitative polymerase chain reaction(RT-qPCR). The CV-A6 representative samples were isolated and the VP1 region of isolates were amplified and analized by Mega5.0 and SeqMen.Results:A total of 7 578 enterovirus-positive specimens were detected from 2017 to 2019, 320 specimens were positive for EV-A71, 1481 specimens were positive for CV-A16, 3171specimens were positive for CV-A6, and 2606 specimens were positive for other enterovirus. Children under the age of 5 years were the most vulnerable population, and the male/female incidence ratio was 1.56∶ 1.The incidence occurred in all seasons, one peak between May and July, the other between September and November. The virus was isolated from 80 CV-A6 positive specimens and the full length of VP1 gene region was sequenced and nucleotide sequence similarity analysis was performed. The nucleotide homology in the VP1 region was 93%-100%, and the amino acid homology was 98%-100%. The nucleotide homology with the CV-A6 prototype strain (Gdula) VP1 region was 79%-81%, and the amino acid homology was 95%-97%. The nucleotide homology with the representative strain of D3 subtype was 92%-98%, and the amino acid homology was 98%-100%. Phylogenetic tree shows that all CV-A6 belonged to the sub-genotype D3 and distributed in multiple branches.Conclusions:CV-A6 is emerging as one of the major pathogen causing HFMD in Guangzhou, and all insolates belonged to D3 subtype. Closely monitoring the molecular characteristics of CV-A6 and changes in the pathogen spectrum can provide scientific basis for HFMD prevention and control.

Objective:To isolate the influenza A (H3N2) viruses from different sources in Guangzhou in 2019 and analyze these viruses' evolution and variation characteristics.Methods:The hemagglutinin (HA) and neuraminidase (NA) genes of H3N2 isolates from outpatient monitoring, influenza outbreaks, and inpatient severe cases in Guangzhou in 2019 were sequenced. Bioinformatics software analyzed the variations and evolution characteristics of HA and NA genes.Results:The epidemic peaks of influenza A (H3N2) viruses were made up of period Ⅰ (from January to August) and period Ⅱ (from November to December). The positive rate of influenza A (H3N2) in males was 13.46% (703/5 221), which was higher than that in females (11.50%, 510/4 435) ( χ 2=8.43, P=0.00). The group's positive rate of 10-20 years old was the highest (25.18%,665/2 641). The isolates from different sources were highly homologous and closely related to 3C.2a.1 branches, which could be further divided into three small groups of Group 1-3. Gene recombination was observed between different branches. The mutations of HA antigen sites gradually appeared from Group 1 to Group 3, leading to new antigen drift. Variations of HA antigenic sites mainly occurred in the region of A and B. The mutations of receptor binding sites of Group 1 and Group 3 viruses occurred in the anterior and posterior walls. There were two glycosylation sites lacked on region A of HA antigen observed in the isolates of Group 2-3. Conclusions:Genetic variations of H3N2 influenza viruses in Guangzhou included gene mutations and gene recombination. Under the pressure of the vaccine, the evolution of viruses was rapid. Therefore, the monitoring of molecular-related epidemic characteristics of the H3N2 influenza virus was necessary.
