Abstract: Objective To investigate the correlation between persistent and non-persistent HPV infection and vaginal microecology and cervical lesions, and to provide the basis for HPV prevention and treatment. Methods In this prospective study, 229 female patients with high-risk type (HR-HPV) were selected for cervical cytology and vaginal microecological examination in the gynecological outpatient department of Baise Maternal and Child Health Hospital from January 2018 to June 2021. The patients were followed up for 1 year to detect persistent HR-HPV infection. The relationship between HR-HPV persistent infection and vaginal microecology and cervical lesions was analyzed using the HPV-negative group as a control. Results Among 229 patients with HR-HPV, there were 109 patients with persistent HR-HPV infection and 120 patients with non-persistent HR-HPV infection in 1-year follow-up, and the incidence of persistent HR-HPV infection was 47.6%. In the HR-HPV persistent and non-persistent infection and HPV-negative groups, the bacterial vaginal incidence was 20.2%, 15.0% and 8.6%, respectively; vulvovaginal candidiasis was 19.3%, 13.3% and 7.9%, respectively; trichomoniasis vaginitis was 12.8%, 9.2% and 4.5%, respectively; mixed infection was 10.1%, 6.7% and 2.7%; H2O2 detection rate was 24.8%, 18.3% and 12.0%,the positive rate of pH value was 52.3%, 40.8% and 36.4%, and microecological normal detection rate was 22.9%, 32.7% and 40.2%, respectively. There were significant differences among the three groups (χ2=10.634, 10.522, 9.010, 9.374, 10.054, 8.268, P<0.01). In the HR-HPV persistent and non-persistent infection groups, the rates of atypical squamous cell detection were 12.8% and 10.0%, and 8.3% and 4.2% for low-grade squamous cell lesions, and 4.6% and 1.7% for high-grade squamous cell carcinoma, 2.8% and 0 for squamous cell carcinoma, respectively. There was no significant difference in the composition of atypical squamous cells between the two groups (χ2=4.358, P>0.05), there were significant differences in the composition of low-grade, high-grade and squamous cell carcinoma (χ2=11.472, 12.685, 11.378, P<0.01). Spearman rank correlation analysis showed that the presence or extent of HPV infection was positively correlated with bacterial vaginosis, vulvovaginal candidiasis, trichomonal vaginitis and mixed infection (P<0.05), positively correlated with H2O2, sialdase, leucocyte esterase,pH positive and positive for all four items (P<0.05), negatively correlated with microecology (P<0.01), positively correlated with low grade, high grade and squamous cell carcinoma (P<0.01), and not significantly correlated with atypical squamous cell carcinoma (P>0.05). Conclusion Persistent cervical HPV infection is an important factor of dysregulation in vaginal microecology and aggravates the degree of dysregulation in vaginal microecology, which is related to the development of cervical lesions.

Background Efficient and lowcost way to isolate keratocytes is helpful for research on cornea.Either relatively expensive or inefficient is the shortage of those means now applied,while raising the keratocytes through passage will change the phenotype of them quickly.Our aim is to approach the way getting keratocytes effectively utilizing modified two step enzymatic digestion by type I collagenase. Objective To evaluate the effect of isolating the bovine keratocytes utilizing two step enzymatic digestion and observe the morphological changes of the keratocytes during cultivation in vitro. Methods Keratocytes were isolated from bovine corneas using 0.5 mg/mL and 1 mg/mL type I collagenase digestion.The harvesting rate and viability rate of the primary keratocytes were evaluated.During the primary cultivation in vitro,the morphological changes of the keratocytes and their F-action distribution were observed.Results(1)The extracellular matrix of the bovine corneas were almost dissolved by the two step enzymatic digestion,followed the keratocytes completely isolated from the solid matrix.The amount of the harvested keratocytes from each cornea was(2.11±0.15)X106 on average while the viability rate was(91.69±3.73)% and the inoculation rate Was(81.20±1.25)%.(2)The primary keratocytes attached and spreaded out with dendritic and stellate morphology.After 3 days cultured,the branches of the keratocytes were contacting and formed networks.The F-actin detected by phalloidin binding showed a limited cortical localization. Conclusion (1)The method of two step enzymatic digestion can make the extracellular matrix of bovine cornea stroma completely degraded with the advantages in high efficiency of harvesting keratocytes and high cell viability and relatively simple manipulation. (2) The primary bovine keratocytes have dendritic morphology and with limited F-action distribute in cellular cortex.

OBJECTIVETo evaluate the clinical effect and safety of dapoxetine in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 116 PE patients to receive dapoxetine on demand at 30 mg qd (dapoxetine group, n = 60, aged 23-49 years) or oral tamsulosin at 20 mg qd (control group, n = 56, aged 24-46 years). After 4 weeks of medication, we compared the clinical global impression of change (CGIC) , PE profile (PEP) scores, intravaginal ejaculation latency time (IELT) , and adverse reactions between the two groups of patients.

RESULTSCompared with the baseline, the IELT was remarkably prolonged after treatment both in the dapoxetine group ([0.86 ± 0.17] vs [4.32 ± 2.23] min, P < 0.05) and the control ([0.88 ± 0.15] vs [4.17 ± 2.26] min, P < 0.05), with no statistically significant difference between the two groups (P > 0. 05). The post-treatment rate of CGIC in the dapoxetine group had no statistically significant difference from that in the control (85.00% vs 82.14%, P > 0.05). In comparison with pre-treatment, the patients of both the dapoxetine and control groups showed dramatically improved scores after medication in perceived control over ejaculation (0.85 ± 0.23 vs 2.13 ± 0.97 and 0.88 ± 0.21 vs 2.06 ± 0.34, both P < 0.05), ejaculation-related personal distress (1.15 ± 0.64 vs 2.89 ± 0.26 and 1.19 ± 0.53 vs 2.82 ± 0.69, both P < 0.05), satisfaction with sexual intercourse (0.81 ± 0.33 vs 2.58 ± 0.37 and 0.79 ± 0.28 vs 2.45 ± 0.32, both P < 0.05), and ejaculation-related interpersonal difficulty (2.05 ± 0.61 vs 3.24 ± 0.35 and 2.03 ± 0.65 vs 3.18 ± 0.76, both P < 0.05), with no significant differences between the two groups (P > 0.05). The incidence of adverse reactions was significantly lower in the dapoxetine than in the control group (3.33% vs 30.36%, P < 0.05).

CONCLUSIONDapoxetine is effective for the treatment of PE, with its advantages of prolonging the intravaginal ejaculation latency time, improving the quality of sexual life, and low incidence of adverse reactions.

Objective To investigate the influence of age on liver histopathological feature of patients infected with chronic hepatitis B. Methods Liver biopsies were performed on 114 patients with chronic hepatitis B. The biochemical tests were measured by routine automated techniques. Serum hepatitis markers including HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc were assayed by using a microparticle enzyme linked immunosorbent assay. HBV-DNA was measured with quantitative polymerase chain reaction assay. The grades of liver necrosis/inflammation and fibrosis were compared between four groups with different age: younger than 20years, 20 ～ 30, 31 ～40, and older than 40 years. Results All 114 patients had liver histological changes with different degree. 75.4 percent (89/114) of cases had 2/over 2 grades of liver necrosis/inflammation, and 47.4 percent (54/114) of cases had 2/over 2 stages of liver fibrosis.There was no significant relation between the level of ALT and age or between the level of ALT and the grades of liver necrosis/inflammation and fibrosis( P ＞0. 05 ). The significant difference in degrees of liver inflammation and fibrosis was found among three age groups ( x2 = 30. 86, P ＜ 0. 01; x2 = 21.17; P ＜0.05 ). The grades of 1 iver inflammation and fibrosis increased with the increased age of the patients. Conclusion These results suggested that age was an independent factor for the disease progression. It was very important to undertake liver biopsy for patients with CHB more than 30 years to reveal the liver histopathological characteristics and guide the treatment.
