The application of colostomy care products in managing the leakage around PTCD drainage tube / 介入放射学杂志

Objective To investigate the application of colostomy care products in managing the leakage around PTCD drainage tube, and to discuss its clinical effect. Methods A total of 56 patients with malignant obstructive jaundice, who had received PTCD and suffered from postoperative leakage around PTCD drainage tube, were randomly and equally divided into the study group (n=28) and the control group (n=28). The colostomy care powder, the skin protective film and the colostomy bag were used for the patients of the study group, while iodophors, sterile gauze and mupirocin ointment were employed for the patients of the control group. The incidence of irritant dermatitis around PTCD drainage tube, the degree of comfort to the indwelling tube judged by the patient, and the nursing workload for PTCD drainage tube were determined, and the results were compared between the two groups. Results The incidence of irritant dermatitis around PTCD drainage tube in the study group was obviously lower than that in the control group. And the degree of comfort to the indwelling tube judged by the patient in the study group was much higher than that in the control group. The differences between the two groups were statistically significant (P<0.05). Conclusion Combination use of colostomy care powder, skin protective film and colostomy bag can effectively reduce the incidence of irritant dermatitis around PTCD drainage tube and improve the patient’s condition. Therefore, this method is worthy of popularization in clinical practice.

Human papillomavirus genotype distribution in invasive squamous cell carcinoma of the uterine cervix in Mongolian women in inner Mongolia autonomy region / 中国医学科学院学报

<p><b>OBJECTIVE</b>To investigate the prevalence of human papillomavirus (HPV) and the HPV genotype distribution in invasive squamous cell carcinoma of the uterine cervix in the Mongolian women in Inner Mongolia autonomy region.</p><p><b>METHODS</b>The prevalence data of HPV in our department were retrospectively reviewed. INNO-LiPA genotyping technique was used to detect HPV genotypes in the reserved carcinoma tissue specimens.</p><p><b>RESULTS</b>Totally 63 tissue specimens were collected and detected. The prevalence of HPV was 93.7%. The positive rates of HPV among different clinical staging and different pathological grading were not significantly different (P >0.05). The prevalence of HPV16 was not significantly different among different age groups (P>0.05). HPV16 (69.8%), HPV18 (4.8%), HPV31 (4.8%), HPV39 (4.8%), and HPV52 (3.2%) were the 5 dominating HPV genotypes in all cases.</p><p><b>CONCLUSIONS</b>HPV infection is closely correlated with invasive squamous cell carcinoma of the uterine cervix in Mongolia women. HPV16 is the most important genotype in invasive squamous cell carcinoma of the uterine cervix, followed by HPV18, 31, and 39. HPV infection dose not affect the progression and differentiation of invasive squamous cell carcinoma of the uterine cervix.</p>

Relationship between Clostridium difficile associated diarrhea and intestinal microecosystem disorder in patients received allogeneic hematopoietic stem cell transplantation / 中国实验血液学杂志

This study was to investigate the relationship between Clostridium difficile associated diarrhea (CDAD) and intestinal microecosystem in patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to clarify clinical characteristics of intestinal microecosystem disorder. Clostridium difficile (CD) was isolated and identified by enzyme-linked-immunosorbent assay using clostridium difficile Premier toxins A&B Kit and anaerobic culture in 44 cases with diarrhea. Fecal flora (bifidobacteria, lactobacillus, bacteroides, peptostreptococcus, Clostridium perfringens, enterobacteriaceae, enterococcus, and yeasts) of patients were quantitatively and qualitatively analyzed by Mitsuoka's methods. The results showed that CDAD occurred after using antibiotic or chemotherapy. Clostridium difficile was detected in 12 patients with diarrhea (positive rate was 27.27%). There was marked changes of intestinal microecosystem when patients suffered from CDAD. The number of lactobacillus, bifidobacteria, bacteroides, enterobacteriaceae and so on decreased significantly. It was effective to treat CDAD with vancomycin, metronidazole and probiotic, but the recurrence rate was 16.67%. In conclusion, CDAD complicated by allo-HSCT is related to change of intestinal microecosystem. While treating CDAD with the sensitive antibiotic, the intestinal flora of patients should be supported actively. This treatment contributes to improving disease status and reducing diarrhea recurrence.
