Objective To explore the difference of the curative effect between incision-thread-drawing procedure and traditional incision drainage in the treatment of perianal abscess.Methods A total of 150 patients diagnosed with perianal abscess and treated at the first time from June 2015 to June 2016 in our department were selected as the research object in this experiment,who were divided into the observation group(75 cases) and control group(75 cases) according to the surgical method.Patients in the observation group were performed with incision-thread-drawing procedure,while the control group were treated by traditional incision drainage.The overall treatment effect,operation time,postoperative recovery time,hospital stay,hospital costs,wound healing time and postoperative complications between the two groups were observed and compared.Results The difference of the overall treatment effects between two groups were not statistically significant(P>0.05).The operation time,the postoperative recovery time,the hospitalization time and the cost,the time of wound healing of observation group were significantly better than the ones of the control group,the differences were statistically significant(P<0.05).The recurrence rates of anal fistula,abscess and other complications in patients of observation group were significantly lower than the ones of control group.The differences were statistically significant(P<0.05).Conclusion Compared with traditional incision drainage,the incision-thread-drawing procedure is more effective with less complications and lower recurrence rate,which should be the first choice for the treatment of perianal abscess.

Tegument protein VP22 is encoded by Pseudorabies Virus (PRV) UL49. To identify the nuclear localization signals of UL49, it is necessary to determine the transport mechanism and biological functions of the VP22 protein. In this study, we identified two nuclear localization signals from UL49, NLS1 (5RKTRVA ADETASGARRR21) and NLS2 (241PGRKGKV247). The functional nuclear localization signal (NLS) of UL49 was identified by constructing truncated or site-specific UL49 mutants. The deletion of both NLS1 and NLS2 abrogated UL49 nuclear accumulation, whereas the deletion of NLS1 or NLS2 did not. Therefore, both NLS1 and NLS2 are critical for the nuclear localization of UL49. And our resuts showed that NLS2 is more important in this regard.

Objective To investigate the prevalence and genotype distribution of human papilloma virus (HPV) infection among patients with cervical carcinoma or precancerous lesions in Xuzhou region. Methods 688 patients with cervical lesions confirmed by colposcopic biopsy were assigned to three groups:low-grade squamous intraepithelial lesion (LSIL) (187 cases), high-grade squamous intraepithelial lesion (HSIL) (359 cases) and cervical carcinoma (142 cases). The genotypes of HPV were determined by nucleic acid hybridization technique. The prevalence and genotype distribution of HPV were further analyzed. Results The infection rates of HPV in LSIL , HSIL and ICC group were 68.98 % (129/187), 94.99 % (341/359), 95.78 % (136/142), respectively. These rates were statistically significant different (P< 0.05). With the aggravation of cervical lesions, HR-HPV infection rate was gradually increased and LR-HPV infection rate was gradually decreased. The most common HPV types were listed below in order of decreasing prevalence. LSIL:HPV16, 52, 58, 18, 31; HSIL: HPV16, 58, 33, 31, 52; cervical carcinoma: HPV16, 31, 58, 18, 33. Based on the cumulative logistic regression model, confidence intervals of the relevance between the overall HPV prevalence and occurrence of cervical lesions were calculated: HPV16 (OR= 7.215, P< 0.05), HPV31 (OR=2.768, P<0.05), HPV33 (OR=1.846, P<0.05), HPV58 (OR=1.726, P<0.05) Conclusions The prevalence of HR-HPV infections increased with the aggravation of cervical carcinoma in Xuzhou region. In order of decreasing prevalence, the most prevalent of HPV types are HPV16, 31, 33, 58. The results indicate that HPV18 have strong tumorigenicity, but is not popular in Xuzhou region. By contrast HPV52 is more common in LSIL than that in cervical carcinoma.

OBJECTIVE To investigate the clinical and etiologic characteristics and treatment of central venous catheter-related(sepsis).METHODS Forty cases of patients with central venous catheter-related sepsis and their clinical manifestation,etiologic profiles and outcome of treatment were retrospectively analyzed.RESULTS Forty six strains were isolated including 23 strains of Gram-positive cocci,19 of Gram-negative bacilli and 4 of fungi.The most frequent(isolates) were Staphylococcus epidermidis.CONCLUSIONS The most common organism causing CRS is S.epidermidis;the key preventive measure is to avoid inner and outer pollution of catheter;antibiotic lock-technique can be taken for the treatment of uncertain CRS.If it is no effect after 24-48 hours,it is necessary to remove venous catheter promptly.

Objective To evaluate superselective external carotid artery embolization before transnasal endoscopic resection in treating nasopharyngeal angiofibroma.Methods Superselective external carotid artery embolization was performed in 20 patients with nasopharyngeal angiofibroma one to three days before transnasal endoscopic resection was carried out.The clinical data,including the volume of blood loss during the surgery,the operative time and the complications,were retrospectively analyzed.Results Superselective external carotid artery embolization was successfully preformed in all 20 patients,which was followed by the transnasal endoscopic resection within 3 days.The average volume of blood loss during the surgery was 155 ml and the total time of operation was 75 minutes.Mild complications occurred in 6 patients after embolization,which were subsided after symptomatic management.No serious complications occurred after surgical resection.The mean hospitalization days of the patients were 3.5 days.Conclusion Preoperative superselective external carotid artery embolization of nasopharyngeal angiofibroma can markedly reduce the blood loss during surgical resection,apparently shorten the operative time and effectively lower the occurrence of complication after the operation.Superselective external carotid artery embolization combined with transnasal endoscopic resection should be regarded as an ideal therapy for nasopharyngeal angiofibroma.
