Chinese Journal of Infection Control 2014;(4):246-248
Objective To analyze the distribution and antimicrobial resistance of Pseudomonasaeruginosa(P. aeruginosa)in a county-level hospital,provide reference for rational antimicrobial use,and promote the control and prevention of healthcare-associated infection (HAI).Methods Data of P.aeruginosaisolated from patients in a hospital between 2010 and 2012 were analyzed statistically.Results A total of 369 P.aeruginosaisolates were iso-lated,strains were mainly from specimens of sputum(n= 234,63.41% ),urine(n= 41,11.11% )and wound(n= 28, 7.59% );most strains were from intensive care unit(n= 146,39.56% ),respiratory diseases department(n= 51, 13.82% )and neurosurgical department(n= 37,10.03% ).P.aeruginosastrains were not resistant to polymyxin B;the resistance rates to imipenem,meropenem,cefoperazone/sulbactam,piperacillin/tazobactam and amikacin were all low(6.81% -22.73% );from 2010 to 2012,resistance rates to antimicrobial agents (except polymyxin B) increased with varying degrees,some antimicrobial agents showed statistical difference(P<0.05).Conclusion P. aeruginosais mainly isolated from respiratory specimens,mainly distributed in departments with serious patients;and resistance to most antimicrobial agents is high,resistance tendency is increasing,surveillance should be intensi-fied.
3.Effect of aiding treatment on patients with dysmenorrhea through psychological intervention
Chinese Journal of Primary Medicine and Pharmacy 2009;16(3):477-478
Objective To study the effect on aiding treatment of patients with dysmenorrhea through psychological intervention.Methods Sixty patients with dysmenorrhea were randomly divied into the intervention group and the control group with 30 cases in each group.The contrd group were treated with allopathy and normal care.On the base of such ineasures,the intervention group were treated with psychological interventions like congnitive regulation,emotion regulation and behavioral regulation.Results The average pain degree of the control group was Ⅱ-Ⅲ.The average pain degree ofthe intervene group Was Ⅰ-Ⅱ.The results ofthe two groups were eonpred.P<0.01 and the difference was significant.The average dose of Atuopin in the control group was 0.60mg.and the average dose of Atuopin in the intervention group was 0.43 mg.P<0.01 and the difference of the two groups is obvious.The average time being in bed in the control group was 5.85 hours,and the average time beingin bed in the intervene group was 3.2.5 hours.The results of the two groups were compared,P<0.01and the difference is significant.Conclusion The intervention can apparently improve patients' symptoms of pain.

Purpose To investigate the expression of secreted frizzled-related protein 4 (SFRP4) and to evaluate its clinical significance in pancreatic ductal adenocarcinoma (PDAC).Methods RT-PCR was performed to analyze SFRP4 mRNA expression level in 30 paired PDAC lesion and matched adjacent non-tuimor tissue.Immunohistochemistry staining detection of 205 matched cases tissue microarray was conducted to explore SFRP4 protein expression pattern.The correlation between SFRP4 and clinical characteristics was also analyzed,including overall survival.Results SFRP4 expression pattern both at mRNA and protein level in PDAC lesion was higher than that in matched adjacent non-tumor tissue.At mRNA level,to found that expression of SFRP4 was elevated in 90% (27/30) of PDAC tissues (P =0.007 2).To found that high expression of SFRP4 was detected in 56.5% (116/205) of PDAC tissue,while only 28.8% (59/205) in the adjacent non-tumor tissue.Moreover,no significant association was observed between SFRP4 expression and clinical characteristics.Kaplan-Meier survival analysis showed high level of SFRP4 expression was correlated with poor overall survival (x2 =3.467,P =0.024).Conclusion SFRP4 can be a novel prognostic biomarker in PDAC.
7. Influence of cultivation medium on growth of tissue cultured seedlings of Polygonatum cyrtonema
Chinese Traditional and Herbal Drugs 2020;51(24):6337-6344
Objective: To find a solution to the problems in the growth of tissue cultured seedlings of Polygonatum cyrtonema, such as low seedling survival rate, poor growth, and leaf disease. Method: In this study, tissue cultured seedlings of P. cyrtonema were used as testing plants. Two types of commercially-available cultivation medium commonly used in Fujian Province, as well as six types of cultivation medium mixed using peat soil, pearlite, roseite, sand, fungi residues and plant ash were used as the raw materials; Among them, a customized nutrient solution was added into the T5 and T7 cultivation media. Besides measuring the physicochemical properties of the cultivation media mentioned above, the study focused on the evaluation of their influence on the rate of grown-up seedlings, biological characteristics, growth biomass, strength index and incidence of leaf disease of P. cyrtonema. It also attempted to find the correlation between the physicochemical properties of the cultivation media and the biological characteristics, growth biomass, as well as the strength index of tissue cultured seedlings of P. cyrtonema. Results: The difference in the cultivation media had a great influence on the tissue cultured seedlings of P. cyrtonema in the rate of grown-up seedlings, biological characteristics, growth biomass, strength index and incidence of leaf disease. The difference in bulk density of the cultivation media had a notable negative correlation with the plant height of the tissue cultured seedlings of P. cyrtonema. The difference in the organic content of the cultivation media had a notable positive correlation with the fresh weight and dry weight of the tissue cultured seedlings of P. cyrtonema. Treated with the T5 cultivation medium we prepared, the tissue cultured seedlings of P. cyrtonema were in better growing condition in the rate of grown-up seedlings, morphological index, growth bomass, strength index, and no disease was found on the leaf. Conclusion: The prepared T5 was worth being widely used as the cultivation medium for growth of tissue cultured seedlings of P. cyrtonema.

Epigenetics change has been considered to be the most promising new strategy for disease control and prevention. TCM regulates gene expression through epigenetics, participating in pathological and physiological process including cell apoptosis, proliferation, differentiation, cell cycle regulation, immunity, inflammation, and metabolism. This article reviewed the application of DNA methylation, histone modification and the miRNA regulation in TCM research.

Objective To investigate the distribution relationship of microglia and neuron in rat medullary visceral zone(MVZ) after stomatic nociception. Methods After 2ml formalin(2.5%)injection in rat stomach by tiny plastic tube,Anti-Fos protein(labeling neuron)and anti-OX 42(labeling microglia)single and double immunohistochemical ABC method staining on model medulla oblongata sections in different time point(0.5h,1h,2h and 3h) were used. Results 1.After wakefulness,the animal models appear restlessness and agitation in 1-2h.2.We found hemorrhage and exfoliation in model's gastric mucosa.3.Fos positive neurons and OX 42 positive microglias were observed in MVZ,whose distribution was congruous and appeared clearly character of locations.4.The results of immunochemical diplex staining indicate that many Fos positive neurons were surrounded by intensive OX 42positive microglias.5.OX 42 positive microglia showed a tendency,which increased in 0.5-2h and decreased in 3h.Conclusion Neurons and microglia in MVZ may be involved in visceral nociception transfer and adjustment function.
