HPV lesions, recurrence tendency, and risk of malignant formation are primarily dependent on the person’s immunity level. GW recurrence is a major challenge in CA treatment. The aim of this study was to explore how lesional auto-transplantation (LT) can be used to treat CA and decrease its recurrence. Methods: We treated CA through the preparation and implantation of tissue from nine CA patients in our dermatology clinic. Transplantation of small pieces of HPV lesions to the subcutaneous fat of the inguinal region was carried out with the help of a simple surgical method under local anesthesia. Patients were followed up for six to eight months. We searched PubMed and the Web of Science for treatment options for CA to compare our treatment method recurrence rate with existing treatment options. Results: During three months of follow-up, seven patients experienced no recurrence of condyloma lesions, while two patients experienced recurrence of small lesions of condyloma acuminatum. The recurrence rate of CA once treated by auto-transplantation was relatively low compared to other CA treatment options. Conclusions: Transplantation of HPV lesions to the inguinal area reduces the recurrence rate in sexually active individuals. The 2/9 recurrence after implantation could be due to poor hygiene, sexual relationships or immune factors.展开更多

Methods: Flow cytometry (permeabization andstaining procedure with conjugated antibodies) wasused. Results: We observed that the expression of Fasprotein on CD4^+ T lymphocyte subset of CA patientswas significantly higher than that of healthy controls(P<0.01). Conclusions: Increased expression of Fas proteinon CD4^+ T lymphocyte subset may be a cause of de-creased percentage of CD4^+ T lymphocyte subset. Thisinduces the increased ratio of CD4^+/CD8^+.展开更多

Results: Upon electron microscopy, the most characteristic feature of the lesions important for diagnosis, was the presence of distinct perinuclear vacuolizations, or so-called koilocytes, among some epithelial cells. These cells possessed hyperchromatic nuclei, swollen mitochondria, dilated endoplasmic reticulum and dissolved glycogen. There were interchromatin granules and perichromatin granules in some nuclei. Moreover some virus particles were also seen in the nuclei of some infected cells. Conclusions: The ultrastructural findings may be used to histopathologically explain the pathogenesis and mechanism of this disease, and it is helpful for diagnosis of CA .展开更多

Methods: Peripheral blood mononuclear cells (PBMC) were isolated from normal healthy individuals (control group) and patients with CA. PBMC were cultured with PHA-P for 48h in vitro. Apoptosis of the PBMC was detected by flow cytometry. Supernatant cytokines (IL-2 and IL-10) were assayed by ELISA. Results: The rate of PBMC apoptosis in both CA group and control group in fresh PBMC was very low and similar in both groups(P>0.05). The rate of PBMC apoptosis within the CA group was noticeably increased compared to that of the control (P<0.001)af-ter PBMC were cultured for 48h. The level of IL-2 was significantly lower in the CA group than in the control group (P<0.001), The level of IL-10 was significantly higher in the CA group compared to thecontrol group(P<0.001). Conclusion: Study results indicate that AICD may affect cellular mediated immune function and play an important role in the pathogenesis of CA.展开更多

Forty-two biopsies from patients with gennital CA and 30 control tissue samples were tested for telomerase activity, HPV presence and types. The telomerase activity was determined by modified telomerase repeat amplification protocol (TRAP) assay and HPV typing by polymerase chain reaction (PCR) with typing-specific primers. Results showed that HPV-DNA was negative and the expression rate of telomerase was 16.7 % in all normal skin samples. All CA samples were positive for HPV (6/11 type was found in 32 cases, 16/18 in 3 and mixed type in 7). Telomerase activity was detectable in all CA patients. The telomerase activity in CA of 16/18 type was apparently higher than in CA of 6/11 type. It was concluded that the hyperplasia in CA might be increased as a result of HPV infection, suggesting that the activation of telomerase by HPV, especially by 16/18 type may play a role in the etiology and carcinogenesis of genital CA.展开更多

Our results showed that mean level of CD40 expression in CA patients was significantly lower than that in the controls （6.58 %±2.74 % vs 14.81 %±6.12 %, t=5. 703, P〈0.05）; the average level of CD40L in CA patients was also significantly lower than that in the controls （0.73 % ±0.54 % vs 2.67 %±2.43 %, t=3. 532, P〈0.05）. Our resutls suggest that the reduced costimulatory interaction of CD40 and CD40L in CA patients may be one of the important factors responsible for the low cellular immunity.展开更多

Methods: Sera were taken from 70 patients with Condylomaacuminatum and compared with 35 healthy controls. PDGFand G-CSF in serum were quantitated using a dual antibodysandwich enzyme-linked immunoabsorbent assay (ELISA). Results: Serum concentrations of PDGF and G-CSF weresignificantly increased in patients with Condylomaacuminatum (CA) compared to controls (P<0.001 and P<0.005respectively). Serum levels of PDGF and G-CSF correlatedwith clinical severity of CA, but no significant difference wasobserved between different duration of disease groups. Asignificant positive correlation was noticed between neutrophilcount and G-CSF levels (γ=0.38, P<0.001), and the neutrophilcount showed no significant correlation with PDGE Conclusion: The results indicated that increased expressionof PDGF an -CSF in peripheral blood might be involved in pathogenesis of CA.展开更多

Therefore, the imitation of the tumor's angiogenic activity (AGA) possibly helps to find a new method to treat ischemic diseases by blood vessel proliferation. Most of the parenchymatous malignant tumors have AGA. We studied the early stage condyloma acuminatum (CA) . After transplanting CA onto the chorioallantoic membrane (CAM) of chick embryos, we observed the AGA of CA and carefully compared it with that of basal cell carcinoma which is generally considered to have strong AGA. Meanwhile, we explored the way by which the AF of CA comes into being. The results demonstrated that CA, a benign neoplastic lesion, at its early stage, also has AGA. It is postulated that the responsible material is a certain form of AF. Therefore, the study on AGA of benign lesions (such as CA) and its physical basis will have potential clinical significance.展开更多

METHODS From May 2002 to April 2004 patients with vulva condyloma acuminatum were examined employing vulva biospy, colposcopy, highrisk HPV-DNA test and cervical bioscopy. RESUTS In 418 cases of vulva condyloma acuminatum, verified by pathologic analysis, high-risk HPV （＋） infections were detected in 68.7% （287/418） of the cases. Among those patients, 20,6% （59/287） had concurrent subclinical cervical intraepithelial neoplastic （CIN） lesions. Among the high-risk HPV（-） 31.3 % （131）, patients 7,6% （10/131） had concurrent subclinical CIN lesions, Pathological examination results： cervicitis, 167 （40.0%）; cervical HPV infection, 182 （43.5%）; CIN-Ⅰ, 51（12.2%）; CIN- Ⅱ, 16 （3.83%）; CIN-Ⅲ, 2 （0,5%）; cervical cancer, none. Another patient had vulva condyloma acuminatum with valva intraepithelial neoplasia （VIN） Ⅱ-Ⅲ, CONCLUSION It was concluded that simultaneous cervical HPV infection of many types,was rather common in patients with vulva condyloma acuminatum. Vulva condyloma acuminatum is the chief clinical symptom which hints at a high possibility of infection with high-risk HPV. The patients are at high-risk for CIN and cervical cancer. We must pay more attention to the cervix in cases with vulva condyloma acuminatum.展开更多
