ObjectiveTo observe the effect of Muscle Stimulating Instrument in enforcing the strength of weaken muscles after selective posterior rhizotomy (SPR). MethodsA group of 27 patients with spastic cerebral palsy aging from 3 to 10 years at the average of 5.7 years were treated with the instrument after SPR. A control group of 36 cases was adopted. Muscle strength, gait and motor function amelioration were compared between two groups. ResultsResults of treatment group in both muscle strength and motor function are better than those of the control group (P<0.05).ConclusionsMuscle stimulating instrument is effective to tone up the muscles which patients felt weak after SPR, and to accelerate the course of rehabilitation.

As a main treatment instrument of limb fractures, the interlocking nail is used in two ways: dynamic fixation and static fixation. The former has less stress shielding but lower satiability. The latter is just the opposite. Therefore, static fixation is the main choice in clinic. But because of the higher stress shielding, complications take place frequently. This article is to discuss the relationship between micromovement and fracture healing, and calls for a new kind of interlocking nail which has micromovement function.

Abstract Benzo [a] pyrene ( B [a] P ) is a well-recognized environmental pollutant. Exposure to B[a]P elicits many adverse biological effects, including tumorigenesis, immunosuppression, teratogenicity, and hormonal effects. In addition to B [a] P exposure-induced genetic damages, a growing number of studies demonstrate that epigenetic changes play an important role in chemically induced carcinogenesis. In order to provide better understanding of epigenetic changes of B [a] P and their potential association with genotoxic endpoints, this review summarizes the advances in the applications of functional genomics in the research of B [a] P toxicity, including functional genomics techniques, regulation of human genome expression, DNA sequence variability, model organisms research, and bioinformatics studies, so as to provide insights into the management of B [a] P exposure-induced health injuries and use of genomics techniques to unravel the mechanisms underlying the toxicity of other environmental pollutants.

Objective To investigate the prevalence of small intestinal bacteria overgrowth (SIBO)in patients with minimal hepatic encephalopathy (MHE). Methods Ninety patients with cirrhosis and 20 healthy volunteers were studied. All of them were assessed with glucose hydrogen breath test (GHBT) to detect SIBO. And number connection test (NCT-A, NCT-BC) and digit symbol test (DST) were used to diagnose MHE. Results One case (5.0%) out of 20 healthy volunteers was SIBO and none was MHE,and 28 cases (31.1%) out of 90 cirrhosis patients were SIBO and 38 cases (42.2%) were MHE. Twenty-one (55.3%,21/38) cases were diagnosed as SIBO among these patients with MHE,and 7 cases (13.5%,7/52)were diagnosed as SIBO among these patients without MHE. There was significant difference between cirrhosis with MHE and cirrhosis without MHE (x2 = 17.90,P＜ 0.01 ). Conclusions Patients with cirrhosis have a higher prevalence of SIBO. The incidence rate of SIBO in cirrhosis patients with MHE is more than that without MHE.

Respiratory tract infection remains a hot clinical topic.Disappointingly, routine microbiology tests do not meet the needs of target antimicrobial therapy.Widespread practice of antibiotic empiricism has lead to dramatic use of broad-spectrum antibiotics and antimicrobial resistance.The application of new clinical microbiology tests to identify the offending pathogen may allow administration of narrow spectrum antibiotic therapy.To do so,the full clinical microbiology armamentarium with newer point-of-care tests and polymerase chain reaction tests must be exploited.The return of the sputum gram stain and introduction of newer molecular tests would provide information for judicious selection of antimicrobials.

Sepsis is featured with acute onset, rapid progress and high mortality.Because its clinical manifestations is very similar to noninfectious systemic inflammatory response syndrome, it is difficult to diffferentiate the two diseases, which results in delayed use or abuse of anti-infective drugs.Procalcitonin is widely recognized as a sepsis biomarker, but it has its limits.Procalcitonin must be interpreted cautiously, in conjunction with the clinical picture.Dynamic monitoring of procalcitonin can give clinicians more help.

Objective To evaluate the effect of treatment and compliance of rebeparzole sodium enteric coated capsules, amoxicillin and clavulanate potassium tablets and furazolidon or levofloxacine treatment of helicobacter pylori infection.Methods Two hundred and forty-nine cases of positive helicobacter pylori infection were randomly divided into three groups.Eighty-one cases of Group A were treated with rebeparzole sodium enteric-coted capsules (20 mg one time), amoxicillin and clavulanate potassium tablets (3 tablets one time) and furazolidon(100 mg one time) ,twice a day before breakfast and supper.Eighty-three cases of Group B were treated with rebeparzole sodium enteric-coted capsules (20 mg one time), amoxicillin and clavulanate potassium tablets (3 tablets one time) and levofloxacine (200 mg one time), twice a day before breakfast and supper.Eighty-five cases of Group C were treated with rebeparzole sodium enteric-coted capsules (20 mg one time) ,clarithromycin capsules(500 mg one time) and amoxicillin dispersible tablets(1 000 mg one time) ,twice a day before breakfast and supper.Period of treatment was 10 days.Results The helicobacter pylori eradication rate of Group A,B and C were 93.83％(76/81) ,89.16％(74/83) and 81.18％(69/85).The eradication rate of Group A was higher than that of Group C (P＜0.05).The comparison between Group A and Group B and between Group B and Group C had no statistically significant difference(P＞0.05).Total integral in average of main digestive symptoms respectively decreased from 12.52±2.24, 12.30±2.42,12.61±2.01 to 3.16±2.23, 3.58±2.39,4.78±2.28 after four-week treatment.The effect of treatment of Group A and Group B was much better than that of Group C(P＜0.05).The incidence of adverse reaction were 11.11％, 30.12％ and 62.35％respectively.Group A and Group B were much lower than Group C (P ＜ 0.05), and Group A was lower than Group B(P＜0.05).In the comparison of the spread of compliance, Group A was the best, the next was Group B,and the last was Group C.The comparison result of those 3 groups was statistically significant (P ＜0.05).Conclusion Ray rabeprazole sodium enteric coated capsules and amoxicillin and clavulanate potassium dispersion tablets combined with furazolidone furazolidone triple therapy in the treatment of Helicobacter pylori Helicobacter pylori infection effect is the best.

Objective To study the skills and safety of breast conserving surgery in radical mastectomy.Methods A total of one hundred and seventy-eight patients with early breast cancer were randomly divided into two groups: 93 cases in the breast conserving surgery group and 85 cases in the radical group,according to the surgical method.The patients in the breast conserving surgery group received stageⅠbreast conserving surgery after modified radical mastectomy for breast cancer,while the patients in the radical group adopted modified radical mastectomy.Then the two groups were compared in terms of postoperative complications,breast appearance evaluation,follow-up on quality of life and tumor recurrence.Results There were not statistically significant differences in postoperative complication rate between the two groups(30.11% vs.23.53%, χ2=0.976,P=0.323);the rate of excellent breast appearance in the conserving surgery group was 86.02%,significantly higher than that of the radical group(38.82%,χ2=42.675,P<0.001);the scores of physiological status,psychologic status,social function and environmental circumstance in the conserving surgery group were significantly higher than those of the radical group,the differences were statistically significant(P<0.05);the difference on tumor recurrence rate of the two groups was not statistically significant(χ2=0.009,P>0.05).Conclusion After radical mastectomy,stageⅠbreast conserving surgery could help patients maintain their breast appearance and improve their life quality,without any increase in the rate of postoperative complications and long-term local morbidity.It is a safe and reliable surgical method.
