Chinese Journal of Radiation Oncology 1992;0(04):-
Objective To study the information absorbency of Chinese Journal of Radiation Oncology and it's half-citing life, find out the core journals and characteristics of literature requested by scientists, and analyze the trend of Radiation Oncology research. Methods The citation analysis is used to analyze the references cited in 475 articles in Chinese Journal of Radiation Oncology from 2001-2004. Results Citation rate is 70.5%,and there are 8.6 citations per article. Main types of citations are journals(91.7%) and books(7.8%). The Price Index is 41.6%,and the self-citation rate is 6.2%. The percent of citations from the high-ranked 20 journals are 57.0%. Conclusions The articles in Chinese Journal of Radiation Oncology concern most journals in the medicine,the most citations are from the English journals. The half-citing life becomes longer than research in 2003. It shows that the use of newly-published articles should be improved.

Journal of Modern Laboratory Medicine 2016;31(5):113-114,117
Objective To understand clinical specimen hemolysis Staphylococcus (SHA)distribution characteristics and re-sistance and sensitivity to 20 kinds of antibiotics,reasonable to guide the clinical treatment of SHA infection.Methods Rou-tinely cultured and isolated bacteria.Used the United States BD Phoenix-100 automated microbial identification and suscepti-bility instrument to identify bacteria and susceptibility testing,and susceptibility testing all used the instrument broth dilu-tion method,according to the USA CLSI2015 [1]regulations standards.Results 162 strains of SHA from the distribution of age,children under the age was one of the highest (30.9%),and from the distribution department,mainly distributed in ped-iatrics (30.9%),department of critical care medicine (22.2%),medicine (17.3%),surgery (12.3%).From the specimen type distribution,were mainly distributed in the blood (33.3%),sputum (25.9%),wound (11.1%) and discharge (9.9%).In the 162 strains of SHA,the proportion of the MRSH was 93.8%,of which 152 strains of MRSH incidence of multiple drug resistance (MDR)was as high as 61.8%.Compared with MSSH,antibiotic resistance rate of MRSH was sig-nificantly higher.The resistance rate of MRSH to ampicillin,cefoxitin,penicillin G,erythromycin was extremely high,more than 98.7% the former of cefoxitin,penicillin G,ampicillin,erythromycin resistance was extremely high,more than 98.7%. The sensitive rate of both to rina thiazole amine,vancomycin,amikacin was 100%,and the rate to Fusidic acid,teicoplanin, nitrofurantoin was also high,more than 9 5.5%.Conclusion Linezolid,Vancomycin,Amikacin,Fusidic acid,Teicoplanin and Nitrofurantoin because all can be used as empiricaluse of SHA infection,other antibiotics chooses to in addition to drug sen-sitivity tests results.

AIM: To evaluate the clinical effects of compound trabeculectomy for primary angle-closure glaucoma with persistent high intraocular pressure.
●METHODS:Thirty-three cases ( 34 eyes ) with primary angle - closure glaucoma were executed compound trabeculectomy. All patients were divided into two groups: group A: 18 cases ( 18 eyes ) were executed compound trabeculectomy under high intraocular pressure higher than 35mmHg after using lOP-lowering medicine for 48-72h; group B: 15 cases (16 eyes) were executed compound trabeculectomy, the intraocular pressure was normal after using lOP-lowering medicine.
●RESULTS:Thirty-four eyes were successfully completed surgery with follow-up of 6 to 18mo and there were no serious complications, including suprachoroidal hemorrhage. The visual acuity before operation in group A and group B were 0. 02 ± 0. 01, 0. 04 ± 0. 02, respectively. And the postoperative visual acuity in group A and group B increased 0.2±0. 06, 0. 3±0. 07, respectively (P<0. 01). All of them, intraocular pressure with 30 eyes were controlled in 9-23 mmHg, 3 eye was controlled by normal through adding in several kinds different lOP-lowering medicine. One eye was failure. Compared to preoperation, postoperative intraocular pressure of two groups were decreased by normal, which were 17. 9 ± 9. 1 mmHg and 15. 4±8. 4mmHg, respectively (P<0. 01). There was no significant difference between two groups for postoperative intraocular pressure.
●CONCLUSION: The primary angle-closure glaucoma with persistent high intraocular pressure should be executed compound trabeculectomy decisively, even under high intraocular pressure, which prevent further damage and loss of visual function. As long as to fully consideration the preoperation, intraoperative careful operation, careful nursing, it is safety and effective to have compound trabeculectomy under the continuous high intraocular pressure for primary angle-closure glaucoma.

Objective To isolate and classigy the bacteriophages specific to Pseudomonas aetuginosa and to investigate biofilm control efficaey of the isolated virulent phages.Methods With P. aeruginosa clinical strains as indicators.bacteriophages were isolated by screening difierent environmental samples.Classification of the isolated phages was done with the methods of restriction fragment analysis of phage genome and host range analysis.Transmission electron microscopy(TEM)was used in phage morphology study.In biogilm control tests,TJC729 was used as the jndicator strain to study the biofilm control efficacy of the isolated phages.Results Total 13 lytic phages specific to P.aeruginosa strains were isolated and named as C1-C13.According to the result of restriction fragment analysis.all 13 phages were double-stranded DNA viruses and could be divided into eight groups.Host range experiments were conducted with 5 laboratory strains and 12 clinical strains of P. aeruginosa.The same infection profiles were observed among phage C1 and C13,C6 and C7,and C9 and C11,respectively.While the remaining 7 phages each had different unique infection profile.Phage C1 was selected randomly to study its morphology.The obtained images showed that phage C1 had an icosahedral head with a non-contractile tail,belonging to the Siphoviridae family.Compared with the single phage,phage cocktail had the best effect on biofilm control.Further experiment results showed that phage C1.C10 and C12 can destroy biofilm after treatment of the biofilm for 24 h.The biofilm amounts were deceased to 32.7%,57.6%and 32.8%of the initial values,respectively.Conclusion Thirteen virulent phages specific to P. aeruginosa had been isolated.The phages could significantly inhibit the biofilm formation and had a certain degree of damage on the biofilm.The results suggested an alternative method for the treatments of P.aeruginosa infections.

Objective To study the value of laparoscopy in the diagnosis and treatment of infertility caused by fallopian tube factors. Methods 210 cases of infertility women caused by fallopian tube factors were studied in terms of adhesiolysis,fallopian tube plasty,fenestration,and patency test were performed.The pregnancy rate was followed up for one year. Results The false negative rate in the diagnosis of fallopian tube patency was 5.43% by hysterosalpingography.It was found that there were 3 cases of genital tract tubercle,80 cases of fallopian tube inflammation,73 cases of inflammation of fallopian tube and overy and 54 cases of hydrosalpingix.Of the later 3 kinds,pelvic inflammation was found to be responsible for 120 cases(57.1%),pelvic endometriosis for 87 cases(41.4%).The pregnancy rate after one year was 50.9%(78/153)for inflammation of fallopian tube and ovary,5.6%(3/54)for hydrosalpingix,respectively. Conclusions Laparoscopy helps to clarify infertility caused by fallopian tube factors,and to improvel the effect of treatment and pregnancy rate.

Objective To evaluate toxicopathological changes of central nervous system in rats at different morphine-dependent time. Methods Animal model of morphine-dependence in rats was established by subcutaneous injection of morphine. Histopathologic changes of coeruleus, periaqueductal gray, substantia nigra, lenticula, corpus amygdaloideun and hippocampus in morphine-dependent rats were observed by microscopy and electron microscopy, and synaptic numbers were counted and compared with those in control animals. Results Six morphine dependence-related regions in morphine-dependent groups were observed. Pyknosis or swelling of the nerve cells, swollen nerve fibers, swollen and deformed mitochondria were detected. Dilated endoplasmic reticulum and disaggregated polyribosomes were observed with increased number in synapsis. Gliocytosis and subpial infiltration of lymphocytes and monocytes became more obvious with extension of dependent time, and glial nodules were formed. Synaptic numbers were significantly increased in morphine-dependent groups at 4 or 8 weeks as compared with those in control group(P
