Chinese Journal of Primary Medicine and Pharmacy 2014;(19):2914-2916
Objective To study DeFazio capsules oxaliplatin neoadjuvant chemotherapy on matrix metallo-proteinase-9 ( MMP-9 ) and vascular endothelial growth factor ( VEGF ) in patients with advanced gastric cancer . Methods 92 patients with advanced gastric cancer were randomly divided into the two groups ,the observation group ( n=46 ) and the control group ( n=46 ) .Both two groups were used neoadjuvant chemotherapy , DeFazio capsules oxaliplatin chemotherapy for the observation group and capecitabine oxaliplatin chemotherapy for the control group . Expression of MMP-9 and VEGF was determined by immunohistochemistry in gastric cancer tissues .Results After chemotherapy,the total effective rate was 60.9%in the control group and 80.4%in the observation group.The total effective rate of the observation group was significantly higher (χ2 =6.42,P<0.05).The anemia,thrombocyto-penia,hepatic dysfunction ,renal dysfunction ,the incidence of nausea and vomiting had no significant differences be-tween the two groups (χ2 =1.52,0.96,2.06,0.00,1.28,all P>0.05).Neutropenia,neurotoxicity in the observation group were less than the control group (χ2 =5.68,4.18,all P<0.05).Before chemotherapy,the positive rates of VEGF and MMP-9 expression in the control group were 93.5%,78.3%.Those of the observation group were 89.1%and 82.6%,respectively,the differences were not significant (χ2 =2.12,2,72,all P>0.05).After the chemothera-py,the positive expression rates of VEGF and MMP-9 in the control group were 45.7%,41.3%,respectively.Those of the observation group were 23.9%and 21.7%,respectively.VEGF and MMP-9 positive expression rates were sig-nificantly lower than before chemotherapy (χ2 =4.72,4.08,10.14,9.84,P<0.05,P<0.01).The observation group was significantly lower than the control group (χ2 =5.14,4.72,all P<0.05).Conclusion DeFazio capsules oxali-platin neoadjuvant chemotherapy can decrease MMP-9 and VEGF expression in patients with advanced gastric cancer .

Objective To investigate the characteristics of distribution and the changes in drug resistance of Enterococci,providing reference for clinical treatment.Methods The distribution and drug resistance in 2547 clinical isolates of Enterococci from 2001 to 2007 in Huzhou Central Hospital and the First People's Hospital of Huzhou were retrospectively analyzed.Results A total of 2547 strains of Enterococci were isolated from 94876 clinical specimens(2.68%),in which Enterococcus faecalis wag primary and Enterococcus faecium Wag ranking the second.The positive rate of Enterococci in urine specimens was the highest,and that in sputum specimens was increasing recently.Enterococci showed higg resistance to erythromycin,rifampin,ciprofloxacin and levofloxacin;Enterococcus faecalis Wag more sensitive to penicillin,ampiciilin and ndtrofurantoin than Enterococcus faecium,while Euterococcus faecium was more sensitive to chloramphended and tetracycline than Enterococcus faecalis;both of them were sensitive to vaneomycin and teicoplanin.Conclusions Enterococcus faecalis and Enterococcus faecium are the common pathogen in Enterococci infections.Enterococci show high drug resistance,so the clinical use of antibiotics should be based on the resuhs of drug sensitivity test.

Objective To study the correlation between individual gene polymorphisms of transforming growth factor (TGF)-β1 + 869 T/C,tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) + 1525 G/A genes and nodular thyroid disease.Methods From September 2007 to December 2009,a total of 544 patients with nodular thyroid disease diagnosed in the Department of Endocrinology,The First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology were selected,including 136 cases of nodular goiter patients (node group),132 cases of thyroid tumor (adenoma group),146 cases of Graves patients (GD group),and 130 cases of Hashimoto's thyroiditis (HT group).One hundred and thirty-five healthy subjects were enrolled as control group.Two milliliters of fasting venous blood of all subjects were collected.Polymorphisms of the TGF-β1 + 869 T/C and the TRAIL 1525 A/G genes were identified by the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and the restriction fragment length polymorphism (PCR-RFLP) methods.Results TGF-β1 + 869 T/C:The CC genotypes and C allele frequencies of nodular goiter group [47.0%(64/136),63.2%(172/ 272)] were significantly higher than those of normal control group [18.0%(22/135),45.2% (122/270); x2 =30.76,17.79,all P < 0.05].The genotypes and allele frequencies of adenoma group[42.4% (56/132),59.1% (156/264)] were significantly higher than those of the normal control group (x2 =24.40,10.34,all P < 0.05).The risk of population carrying the C allele suffering from nodular goiter was 2.086 times of those carrying the T allele (OR =2.086; 95% CI:1.480-2.943).The risk of population carrying the C allele suffering from adenoma was 1.752 times of those carrying the T allele (OR =1.752,95% CI:1.244-2.469).TRAIL + 1525 G/A:the genotypes and allele frequencies of nodular goiter group [40.4% (55/136),62.9% (171/272)] were significantly higher than those of normal control group [12.0% (16/135),48.5% (131/270); x2 =9.176,11.307,all P < 0.05].The genotypes and allele frequencies of adenoma group[53.3% (70/132),73.1% (193/264)] were significantly higher than those of the normal control group (x2 =9.806,33.82,all P < 0.05).The risk of population carrying the G allele suffering from nodular goiter was 1.796 times of those carrying the A allele (OR =1.796,95% CI:1.275-2.531).The risk of population carrying the G allele suffering from adenoma was 2.884 times of those carrying the A allele (OR =2.884,95% CI:2.009-4.142).Conclusions TGF-β1 + 869 T/C and TRAIL + 1525 G/A gene polymorphisms may be related to the incidence of nodular thyroid diseases; G allele of TRAIL and C allele of TGF-β1 may be predisposing genes of patients with nodular goiter.

Objective:To analyze the operation status of official voice in Beijing municipal hospitals and explore the countermeasures to optimize the operation of official short video tiktok.Methods:The 21 Beijing municipal tertiary public hospitals were selected as the research objects. The 17 tiktok numbers which had been approved by the hospital as of December 31, 2020 were included. The data of basic accounts, fans, points, themes, contents, and number of periodicity were analyzed. The theme and the number of praise of the short video tiktok that broke through 10 thousand times were analyzed. The current situation and problems of official voice in Beijing municipal hospitals were analyzed.Results:The 17 official tiktok accounts of the hospital issued 2 059 pieces of tiktok, 1 737.5 thousand fans, and 9 231.8 thousand times of points, the average number of entries was 4.5 thousand times. The official tiktok construction of Beijing municipal hospitals was still in its infancy. The problems included: the weakening of IP image and the lack of system design, lack of content productivity and interaction, unclear positioning and lack of operation strategy.Conclusions:The optimization of hospital official tiktok operation needs to properly handle the relationship between science and interest, systematicness and efficiency. We should clarify the account positioning, improve productivity, strengthen interaction, enhance linkage, and do a good job in supervision.

In the all-media era, communication channels are increasingly diversified and the modes of communication are undergoing profound changes. Same medical institutions ignore the development of all media, which lead to rigid and backward communication situation, affect the healthy development of medical and health undertakings. Mastering and making good use of the advantages and characteristics of communication in the all-media era will also provide more motivation and possibilities for strengthening ideological work. This paper expounded the significance of strengthening the dissemination of socialist ideology in hospitals, proposed the opportunities and challenges faced by hospitals in strengthening the dissemination of socialist ideology in the all-media era, and then put forward specific coping strategies combined with the actual situation of hospitals.
