ABSTRACT
Objective:To investigate the clinical efficacy of conservative and surgical treatment of testicular appendage torsion in children and to summarize the experience.Methods:The clinical data of 106 children with testicular appendage torsion admitted in Tengzhou Central People's Hospital Affiliated to Xuzhou Medical University from January 2012 to December 2018 were retrospectively analyzed. According to different therapeutic methods, all the children were divided into conservative group (25 cases) and surgical group (81 cases). The clinical efficacy was compared between the two groups.Results:106 children with testicular appendage torsion were cured. The hospitalization time [(5.61±1.04)d vs (11.32±1.89)d], pain relief time [(9.11±2.56)d vs (68.5±19.87)d], disappearance time of scrotal edema [(5.11±1.08)d vs (10.56±1.50)d] and the utility time of antibiotic [(4.89±1.32)d vs (7.06±1.26)d] in the surgical group were shorter than those in the conservative group, with statistically significant difference(all P<0.05). After 6 months of follow-up, there were no cases of recurrence and discomfort in the two groups. Conclusions:Children with testicular appendage torsion should be actively treated with surgery, which can not only significantly shorten the course of disease, but also reduce the incidence of complications and missed diagnosis. For children who with testicular appendage torsion, surgeries should be performed actively. It can significantly shorten the duration of symptoms, but also reduce the occurrence of complication and the occurrence probability of misdiagnosis.
ABSTRACT
Objective To observe the efficacy of a rotating magnetic field and granisetron hydrochloride in preventing nausea and vomiting caused by a eisplatin regimen, and any side effects. Methods Sixty-eight patients receiving cisplatin regimen chemotherapy were randomly assigned to two groups: a magnetic treatment group and a drug treatment group. The patients in the two groups were exposed to a rotating magnetic field or received granisetron hydrochloride, respectively. The effects of the treatments were observed. Results Both treatments could effectively prevent and treat the vomiting caused by chemotherapy. The rate of response to the rotating magnetic field was 88.2% and to the drug 91.2%. However, tardive vomiting was significantly better controlled in the rotating magnetic field group. The incidence of side effects in the magnetic field group was 20.6% , and in the drug treatment group it was 45.6%. Conclusion The efficacy of a rotating magnetic field and granisetron in treating acute vomiting were simi- lar. The rotating magnetic field was more effective in preventing tardive vomiting and had fewer side effects. Magnetic therapy should be more generally applied in clinical practice.
ABSTRACT
Objective: To observe the safety and clinical efficacy of tumor antigen-pulsed dendritic cell(DC) vaccine in treatment of advanced malignant tumor.Methods: Ninety-one patients with non-small cell lung cancer,colon and rectal cancer,melanoma,renal carcinoma,breast cancer and other malignant tumors were enrolled in this study.All patients met the selecting standard and signed informed consent.Human dendritic cells were obtained from peripheral blood monocytes by culturing them with granulocyte macrophage-colony stimulating factor and interleukin-4.DC vaccine was prepared from tumor antigen pulsed immature dendritic cells in vitro.Patients received the vaccine therapy once every week and one cycle was defined as once every week for 3 weeks.Results: All the patients received 96 cycles of DC vaccine treatment.Symptoms of toxicity included fever,shivering,aching pain of muscle,asthenia,itching,stifle and transient fatigue;most of the symptoms automatically recovered.Clinical efficacy of the treatment was evaluated in 76 patients.Thirty-one of the 76 patients were stable after treatment and 45 were in progressive situation,with the clinical benefiting rate being 40.8%.Eighty-five patients were followed up.The median time for progression was 2.6 months;the overall survival time was 0.9-30.6 months;and the median survival period was 4.5 months,with the one year survival rate being 9.2%.Conclusion: The results suggest that the DC vaccine therapy is well tolerated in treating patients with advanced malignant tumors and has satisfactory clinical benefit;the clinical value of DC vaccine therapy needs to be further observed.
ABSTRACT
Objective To study the significance of AP-PCR i n identification and subtyping of der-matophytes.Methods Using a pair of random primers,OPAA11(5' -ACCCGACCTG -3' ),and OPD18(5' -GAGAGCCAAC -3' )the DNAs of 64isolates of dermatophytes(9species of 3genera),Sporothrix schenckii and Candida albicans were amplified by AP-PCR and analyse d by electrophoresis.Results Distinct DNA band patterns were observed in diffe rent dermatophyte species.Common major DNA bands were observed in Trichophyton rubrum isolated from different areas with s train difference.Conclusion Using OPAA11and OPD18as primers,AP-PCR may be applied in the identification and subtypi ng of dermatophytes.
ABSTRACT
Objective To explore the relationship of genomic characte ristics,virulence of S.schenckii and clinical patterns of sporotrichosis.Met hods Isolates of S.schenckii were collected from different clinical patterns of sporotrichosis.Genomic DNAs of S.schenckii isolates were amplified by rando mly amplified polymorphic DNA (RAPD).Suspensions of different isolates of S.sc henckii were inoculated into BALB/c mice in order to observe their pathogenicity.Histopathology of the skin and viscera of the mice was studied to determine th e numbers and distribution of spores.Results The electrophoretic profiles of PCR products differed in the isolates from different clinical patterns of sporo trichosis:1 800 bp,850 bp,500 bp,and 180 bp in disseminated sporotrichosis;1 400 bp,800 bp,700bp,and 500 bp in the regional lymphangitic sporotrichosis,2 500 bp,1400 bp,1000 bp,and 700 bp in fixed cutaneous sporotrichosis.The earl ier onset of illness,wider distribution of lesions and higher mortality rate we re observed in the BALB/c mice inoculated with isolates from disseminated sporot richosis,followed by those from regional lymphangitic sporotrichosis and those from fixed cutaneous sporotrichosis.Histopathologically more spores were found in the mice inoculated by isolates from disseminated sporotrichosis,followed by those from regional lymphangitic sporotrichosis and those from fixed cutaneous sporotrichosis.Conclusions There is a strong correlation among genomic charac teristics,virulence of S.schenckii and clinical patterns of sporotrichosis.
