We reported a case of giant solitary fibrous tumor of vagina and reviewed literature. The clinical features, diagnosis, and treatment schemes for the disease were summarized to improve the understanding of the disease. An elder female patient came to the Third Xiangya Hospital, Central South University, because of abdominal distention and pain for 5 days after menopause for 9 years. The patient was diagnosed as a solitary fibrous tumor of vagina by pathology and immunohistochemistry after complete resection. The tumor size of the patient was the largest according to reported literature, and the tumor recurred 10 months after surgery. The strong positive expression of CD34 and high Ki-67 proliferation index in tumor immunohistochemistry indicate that the prognosis of patients will be poor.

Objective:To analyze the clinical materials of the patient with Van Wyk and Grumbach syndrome (VWGS),and to explore the pathogenesis,clinical characteristics,diagnosis,differential diagnosis and treatment method.Methods:The clinical data of a patient with VWGS was analyzed retrospectively.Results:The patient presented autoimmune thyroiditis, sever long-standing hypothyroidism, bilateral ovarian cysts, hyperprolactinaemia and a secondary pituitary adenoma. After thyroxine replacement treatment, the thyroid function and prolactin (PRL)level recovered to the normal levels and the ovarian cyst was shrunk within 1 month. Conclusion:The clinical manifestation of VWGS is special.And it’s easy to misdiagnose this syndrome as pituitary adenoma or ovary cyst and then operation is performed.Thyroid hormone replacement can completely resolve the symptoms and hormone abnormalities.Grasping the clinical characteristics of this syndrome and making correct diagnosis is critical to avoid unnecessary operation.

A case of primary yolk sac tumor of endometrium was retrospectively analyzed and relevant literature was systematically reviewed. We found that the primary yolk sac tumor of endometrium showed low incidence rate and was clinically characterized by abnormal vaginal bleeding, intrauterine lesions and significantly elevated alpha-fetoprotein (AFP) level. The final diagnosis should be confirmed by pathological examination. There is no guideline for the treatment of primary yolk sac tumor of endometrium due to its rareness. For now, surgery and chemotherapy are the major therapies and the curative effect is satisfactory in some cases.

Gestational trophoblastic tumors (GTTs) are malignant lesions that often cause abnormal genital bleeding and may present with hemoptysis, intraperitoneal bleeding or acute neurologic deficits. GTTs are generally highly chemosensitive with more favorable outcomes than other comparable malignancies. Here we report a rare case of invasive mole (FIGO stage IV, WHO score16) presenting with renal subcapsular hematoma due to bleeding renal metastasis. The patient had a pretreatment β-human chorionic gonadotrophin (β-HCG) level of 462 047 mIU/ml and received combined chemotherapy with etoposide, methotrexate, actinomycin-D, cyclophosphamide and vincristine with also adjuvant surgeries including hysterectomy and nephrectomy. The patient recovered well and the tumor has remained in complete remission for one year and a half.

OBJECTIVE: To evaluate the genital human papillomavirus (HPV) infection in patients from gynecology clinic, and to investigate the association of persistent HPV infection with cervical lesions. METHODS: From January, 2009 to December, 2013, clinical data of 16 320 patients in Third Xiangya Hospital were collected. A retrospective analysis was carried out to evaluate the overall prevalence of HPV infection. The prevalence of HPV infection in different ages and subtypes were compared. The prevalence of persistent HPV infection and results of cervical cytology were analyzed. RESULTS: The overall HPV prevalence was 26.54%. The lowest overall and high-risk HPV prevalence were found in women at the age of 30-39 years old (P<0.05); the highest ones were found at the age of over 60 years old, with significant difference among the aged groups (P<0.05). There was no significant difference in low-risk HPV prevalence among the aged groups (P=0.693). The clearance rate of HPV was 87.65% one year later. There was no significant difference in high-risk and low-risk HPV infection between the non-persistent positive group and the persistent positive group (P=0.545), but the difference in single and multiple subtypes infection between these 2 groups was significant (P<0.05). In the persistent positive group, the most common genotypes were HPV 16, 52, 58, CP8304, and 33. The incidence of ASC-US, HSIL or SCC was significantly increased in the persistent positive group. CONCLUSION Persistent HPV infection mainly consists of multiple and high-risk HPV infection. It is necessary to focus on the prevention of HPV 16, 52 and 58 persistent infection in our region.

OBJECTIVE: To investigate the effect of nano-realgar on proliferation and apoptosis of cervical cancer cells.
 METHODS: Different cervical cancer cell lines (Caski/HPV16+, adeno carcinoma; Hela/HPV18+, squmous carcinoma; C33A/HPV-, adeno carcinoma) were incubated with nano-realgar at different concentrations (5, 10, 20, 40 mg/L) for different times (24, 48, 72, 96 h). The morphology was observed under phase contrast microscope. The cell viability and apoptosis were examined by MTT and flow cytometry, respectively.
 RESULTS: The inhibitory effect of nano-realgar on the proliferation of cervical cancer cells was in a dose-dependent manner, with a range of inhibitory rate from 9.02% to 49.06%. Taking the group (20 mg/L) for an example, the inhibitory rates for Caski, Hela and C33A were 39.15%, 36.17% and 30.56%, respectively. The results of flow cytometry showed that the nano-realgar induced apoptosis in a concentration-dependent manner, with a range of apoptosis rate from 19.29% to 99.54%. Also taking the group (20 mg/L) for an example, the apoptosis rates for Caski, Hela and C33A were (60.43 ± 2.88)%, (41.95 ± 3.01)% and (43.49 ± 2.19)%, respectively. High concentration of nano-realgar (20 or 40 mg/L) could induce block of Hela and Caski at G2/M stage.
 CONCLUSION Nano-realgar can inhibit the proliferation of different cervical carcinoma cell lines and can induce the cell apoptosis. The inhibitory effect on cell proliferation is strongest for Caski, followed by Hela and C33A. It can also induce G2/M stage block on HPV positive cervical cancer cells at high enough concentration.

Objective To investigate the role of Stat1 gene in the proliferation and chemotherapeutic sensitivity of cervical cancer HeLa cells. Methods The protein expression of Stat1 in the Hela cells exposed to gradient concentrations of cisplatin (DDP) was detected by Western blotting with or without small interfering RNA (siRNA)-mediated Stat1 gene silencing. The effect of Sata1 silencing on the sensitivity to DDP and cell proliferation of the cells was tested using MTT assay and BrdU assay, and the expression of c-Myc was detected by Western blotting in the cells treated with siRNA and DDP. Results The expression of Stat1 in Hela cells exposed to DDP increased with the DDP concentrations, reaching 1.5 folds of the baseline at a DDP concentration of 5 mg/L and 2 folds at 10 mg/L. Stat1-siRNA effectively reduced Stat1 expression in Hela cells, promoted the cell proliferation, and enhanced the expression of c-Myc;DDP inhibited the cell growth and down-regulated c-Myc expression. Stat1-siRNA rescued DDP-induced inhibition of cell growth and c-Myc down-regulation. Conclusion The expression of Stat1 is associated with DDP sensitivity in cervical cancer cells, and Stat1 silencing can increase the sensitivity to DDP and c-Myc expression of the cells.
