RESUMO
Objective To analyze the resistance genes of multidrug-resistant Pseudomonas aeruginosa by high throughput sequencing and bioinformatics.Methods Multiple drug-resistant strains were screened from 246 strains of Pseudomonas aeruginosa.The genome and plasmid DNA of target bacteria were extracted by al-kaline lysis and sequenced by high throughput.The resistance genes were analyzed by bioinformatics.Results 102 strains of multidrug resistant strains were detected,21 strains of extensively drug resistant strains of poly-myxin B sensitive.102 strains of multidrug resistant Pseudomonas aeruginosa samples by high-throughput se-quencing generated reads 32 088 766,the total length of 98 nt,sequencing base 3.1 Gb,8 types of antibiotic re-sistance were found,containing 21 kinds of resistant genotypes,a total of 16 polymorphic loci gene had 69 nu-cleotides,including 8 genotypes of 17 loci the occurrence of non-synonymous mutations,total 24.6% SNP loci. Conclusion Analysis of the use of multi drug resistant pathogen resistant bacteria has the feasibility of high-throughput gene sequencing technology hybrid genome.
RESUMO
Objective To evaluate the efficacy and safety of double dosage Tamsulosin in treating patients with type Ⅲ prostatitis.Methods According to the results of prostate secretion(EPS) examination and the national institute health-chronic prostatitis symptom index(NIH-CPSI) questionnaire,120 patients with type Ⅲ prostatitis were recruited and randomly divided into single dosage group (n =60),treated with 0.2 mg Tamsulosin and placebo once daily for 12 weeks,and double dosage group (n =60),treated with 0.4mg Tamsulosin once daily for 12 weeks.Before treatment,the NIH-CPSI total scores in single and double dosage group were 26.91 ± 4.08 and 27.31 ± 4.98,respectively.The pain index in each group was 10.64±2.23 and 11.47 ± 3.00,respectively.The voiding index was 6.52 ± 2.24 and 6.41 ± 2.97 respectively.In those groups,the quality of life index was 9.68 ± 1.81 and 9.45 ± 1.79,respectively.All those items didn't show significant difference among those groups (P ＞ 0.05).The patients were follow-up and evaluate by those items on weeks 12.Results Because of losing during follow-up,4 patients were excluded from single dosage group.2 patients were excluded from double dosage group.After treatment in single dosage group,the NIH-CPSI total scores were 12.11 ± 3.60,pain index were 3.57 ± 1.67,voiding index were 2.88 ± 1.70,quality of life index were5.59 ± 2.06.After treatment in double dosage group,the NIH-CPSI total scores were 9.90 ± 4.15,pain index were 3.21 ± 2.21,voiding index were 2.21 ± 2.11,quality of life index were 4.50 ± 1.97.After 12 weeks treatment,the NIH-CPSI total scores,pain index,voiding index,quality of life index in both two groups were improved (P ＜ 0.05),and the double dosage group improve better(P ＜ 0.05).In the course of treatment,there were 2 cases of patients (3.8％) with adverse drug reactions in single dosage group,including dizziness in 1 case,headache in 1 cases.There were 4 cases of patients (6.9％) with adverse drug reactions in double dosage group,including dizziness in 3 cases of and rhinitis in 1 case.The rate of adverse reactions had no significant differences in the two groups (P ＞ 0.05).Conclusions Compared with single dosage Tamsulosin in the treatment of type Ⅲ prostatitis,double therapy had a better efficacy.Double dosage Tamsulosin therapy had an equal safety to the single dosage Tamsulosin.
RESUMO
Objective To evaluate the feasibility and safety of transumbilical laparoendoscopic sin-gle-site dismembered pyeloplasty ( U-LESS-P ) for the treatment of ureteropelvic junction obstruction (UPJO). Methods Between Mar.2011 and Mar.2012, U-LESS-P was performed in 8 consecutive pa-tients with UPJO by one experienced laparoscopic surgeon .The patients included 5 males and 3 females, with an average age of 28 (16-45) years.Of the 8 patients, six presented with flank pain , and two were a-symptomatic and discovered incidentally by health check .Of the 8 patients, seven had UPJO on the left side and one on the right side .The diagnosis was established by renal ultrasonography , diuretic renal scan , intra-venous urography (IVU) or/and computed tomography urography (CTU).Renal ultrasonography, IVU and ( or) CTU showed hydronephrosis and UPJO in the affected side , while diuretic renal scan demonstrated re-nal function deteriorated .No patients had undergone abdominal surgery previously .A 2-2.5 cm umbilical in-cision was made for single-port access .The procedures were performed using 30°5 mm or 10 mm laparoscope with a combination of conventional and bent laparoscopic instruments . Results All procedures were com-pleted successfully .None was converted to open surgery or traditional laparoscopic surgery .The mean opera-tive time was 153 (117-190) min, and the average estimated blood loss about 20 (10-40) ml.The mean time to resume oral diet was 1.5 days.The drainage remained 2-7 days.The mean hospital stay was 6 (4-8) days.With the follow-up of 3-6 months, symptom-free was investigated in all 8 cases.Ultrasonography , diuretic renal scan and IVU showed decreased or disappeared hydronephrosis .No operative complication , such as anastomotic stoma stenosis , was founded . Conclusions U-LESS-P is a safe and effective proce-dure for the treatment of UPJO , with the advantages of decreased operative morbidity , postoperative rapid re-covery and improved cosmetic result .
RESUMO
Currently endoscopic retrograde cholangiopancreatograhp(ERCP) has been one of the major treatments to diagnose and cure pancreatic and choledochal diseases in many large and medium-sized hospitals.To meet the requirements of the army,ERCP treatment is practiced in field battle X-ray diagnosis vehicle(Model XCY2002-1/200) and has achieved satisfactory effects.The functions of field battle X-ray diagnosis vehicle in model of XCY2002-1/200 are expanded and new access are explored to cure patients with pancreatic and choledochal diseases in the field.
RESUMO
New field battle X-ray vehicle(model XCY2002-1/200) is used usually and control method is grasped too. By analyzing operation capability, the advantages and disadvantages are found, and then corresponding improvement is proposed to educe efficiency of medical support.
