Aim To compare thermocoagulation and cryotherapy for treatment of high‐grade cervical intraepithelial neoplasia (CIN). Methods From May 2017 to May 2018, women with CIN2/3 were randomized to thermocoagulation or cryotherapy at Peking University Shenzhen Hospital. Follow‐up at 4 and 8 months included cytology and human papillomavirus (HPV) testing. Women who were HPV‐positive or had atypical squamous cells of undetermined significance or higher‐grade disease underwent colposcopy/biopsy. Results Among 149 women enrolled, 74 were randomized to thermocoagulation, and 75 to cryotherapy (excluded four were immediately referred for thermocoagulation due to large lesions). At follow‐up, there was no difference between the thermocoagulation and cryotherapy groups in HPV‐negative (4/8 months: 72.5%/86.2% vs 68.6%/80.6%) and pathology‐negative (97.1%/98.5% vs 94.3%/92.3%) rates (all P > 0.05). The cytology‐negative rate was similar for thermocoagulation and cryotherapy at 4 months (79.7% vs 78.9%, P > 0.05), but higher for thermocoagulation at 8 months (100% vs 88.7%, P

Psoriasis is a chronic, recurrent inflammatory autoimmune skin disease. Although its etiology and pathogenesis are complex and multifarious, it has been proved to be closely related to dysregulation of immune cell function as well as keratinocyte proliferation/differentiation. Our previous study demonstrated that miRNA-210 (miR-210) plays an important role in the formation of skin lesions and immune imbalance in psoriasis. Here, we developed a biomimetic reconstituted high-density lipoprotein (rHDL) nanocarrier gel containing miR-210 antisense (NG-anti-miR-210) to investigate its effect on imiquimod (IMQ)-induced psoriasis-like dermatitis in mice. We found that topical treatment with NG-anti-miR-210 significantly decreased the expression of miR-210 in both the skin lesions and splenic CD4+ T cells from IMQ-induced psoriasis-like mouse models and ameliorated the dermatitis in terms of the erythema, scales, acanthosis and dermal inflammatory cell infiltration in IMQ-induced mice. In addition, the proportion of T-helper (Th)1 and Th17 cells in dermal and splenic cells of IMQ-treated mice were decreased by application of NG-anti-miR-210, accompanied by decreased interleukin-17A and γ-interferon mRNA levels. Therefore, our data demonstrate that topical inhibition of miR-210 delivered by rHDL nanocarrier effectively alleviates the psoriasis-like inflammation in mice and provides a potentially effective topical drug for psoriasis.

Aim To compare the therapeutic effect of 1.88-mg and 3.75-mg gonadotrophin-releasing hormone agonist (GnRHa) in the treatment of stage III–IV endometriosis after laparoscopic surgery. Methods Fifty patients with stage III–IV endometriosis diagnosed on laparoscopy were randomized into two groups according to GnRHa dose. Sex hormone level, symptoms of estrogen deficiency and lumbar vertebrae bone density were compared and analyzed between the two groups. Results Bone density was decreased in both groups at 20 weeks after treatment, and the degree of bone density loss in the full-dose group (5.6%) was higher than in the half-dose group (1.2%; P 0.05) after resumption of menstruation. Both groups had symptoms of perimenopause at 8 weeks after treatment (P > 0.05), but change in Kupperman score with time differed between the groups. At 16, 20 weeks after treatment, the symptoms of perimenopause in the half-dose group were improved, and Kupperman score was lower than at 8 weeks after treatment. In the full-dose group, however, Kupperman score was higher than at 8 weeks after treatment and higher than in the half-dose group (P 0.05). Estradiol (E2) in the full-dose group was significantly lower than in the half-dose group (P

Chemotherapy can lead to the loss of fertility and premature ovarian failure in young women who suffer from malignant diseases. Freezing ovarian tissue by vitrification allows for the preservation of a large number of follicles prior to treatment, yet no established protocols have been optimized with respect to the vitrification solution. The aim of the present study was to evaluate the early stage of human ovarian tissue xenotransplantated onto the chick embryo chorioallantoic membrane after vitrification, and to determine the effect of different vitrification solutions on ovarian tissue quality-as defined by morphology and viability of follicles, neovascularization, cell proliferation, and apoptosis. Each vitrification protocol had a different impact on ovarian tissue at the early transplantation stage; one process using the lowest concentrations of ethylene glycol and dimethylsulfoxide, plus sucrose, demonstrated a moderate advantage compared to the other protocols. We also demonstrated that the chorioallantoic membrane model can be a useful alternative for short-term xenotransplantation studies of angiogenesis into human ovarian cortical tissue.

Select cancer registries report that cervical cancer is relatively rare in the People's Republic of China, but may not be representative of the entire country. We carried out a survey of human papillomavirus (HPV) prevalence in 3 samples of women, i.e., general population, factory workers, and tertiary sector workers, in Shenzhen City in 2004. All participants were interviewed and offered gynaecological examination. HPV detection in exfoliated cervical cells was performed using a GP5+/6+ PCR-based assay. Overall HPV prevalence was 18.4% among the general population (n = 534), 11.2% among factory workers (n = 269) and 18.8% among tertiary sector workers (n = 224). Corresponding prevalence for high-risk HPV types was 13.5%, 8.2% and 13.8%, respectively. The most commonly found HPV types were HPV16, 52, 58, 31 and 39. HPV prevalence significantly increased with age in the general population, whereas it was highest below age 25 years in tertiary sector workers. Associations of HPV prevalence with indicators of sexual behaviour were stronger among tertiary sector workers than in the other samples of women. High HPV prevalence in all age groups and the appearance of a 'western-type' peak in HPV prevalence among young women employed in the tertiary sector raise important questions concerning the real cervical cancer burden, and its control, in urban China.
