Objective To investigate the clinical significance of thyroglobulin antibody (ATG) and thyroid peroxidase antibody (ATPO) in patients with vitiligo. Methods Venous blood samples were obtained from 87 patients with vitiligo and 90 age- and sex-matched normal human controls. Chemiluminescence was applied to measure the serum levels of ATG, ATPO, free triiodothyronine, free tetraiodothyronine and thyroid stimulating hormone (TSH). Results There was a significant increase in the positivity rates of ATG (23.0% vs 6.7%, P < 0.01) and ATPO (24.1% vs 7.8%, P < 0.01) as well as the serum level of TSH (3.4 ± 2.4 vs 2.4 ± 1.2 pmol/L, P < 0.05) in the patients with vitiligo compared with the normal human controls. It is worth mentioning that all patients positive for ATG or ATPO were diagnosed with vitiligo vulgaris. The positivity rates of ATG and ATPO in patients with vitiligo aged from 11 to 20 years and 21 to 40 years were significantly higher than those in age-matched normal controls (all P < 0.05). Also, female patients had a higher positivity rate of ATG and ATPO than female controls did (34.1% vs 8.5%, χ2 = 8.90, P < 0.01; 34.1% vs 10.6%,χ2 = 7.29, P < 0.05). The highest positivity rates of both ATG and ATPO were 53.3%, which were observed in vitiligo patients aged from 11 to 20 years, followed by patients from 21 to 40 years (ATG 34.5%, ATPO 34.5%). In patients with vitiligo positive for both ATG and ATPO, the occurrence of autoimmune thyroid disease was 70% (14/20), significantly higher than that in ATG- and ATPO- positive healthy controls (16.7%, χ2 = 5.4, P < 0.05). Conclusions ATG and ATPO were observed in young female patients with vitiligo vulgaris, and they may be associated with the development of autoimmune thyroid diseases.

OBJECTIVE:To evaluate the effects of the implementation of National Essential Medicine System on the utilization rate of hormone drugs in primary medical institutions in China systematically.METHODS:Retrieved from CJFD,Wanfang database and VIP,the literatures about the use of hormone drugs were collected before and after the implementation of National Essential Medicine System.Meta-analysis was performed by using Stata 13.0 software after utilization rate dam extraction and quality evaluation with Cochrane system evaluator manual 5.1.0.RESULTS:A total of 20 literatures were included.Results of Meta-analysis showed that utilization rate of hormone drugs after the implementation of National Essential Medicine System was significantly lower than before implementation,with statistical significance [RD =-0.03,95 ％ CI (-0.05,-0.02),P＜ 0.001].Results of subgroup Meta-analysis of utilization rate of hormone drugs in different areas before and after the implementation of National Essential Medicine System showed that the utilization rate of hormone drugs in eastern areas was significantly lower after the implementation of National Essential Medicine System than before [RD=-0.06,95％ CI(0.09,-0.03),P=0.001] with statistical significance.There was no statistical significance in the utilization rate of hormone drugs in middle area [RD=-0.02,95 ％ CI(0.06,0.02),P=0.235] or western area [RD=-0.01,95％ CI (-0.02,0),P=0.122] before and after the implementation of National Essential Medicine System.CONCLUSIONS:The implementation of National Essential Medicine System reduces the utilization of hormone drugs in primary medical institutions.The effect of the eastern area is more obvious than in middle and western area.

Objective To analyse the high-risk human papilloma virus (HPV) infection in women, and to analyze the protective effect of bivalent HPV vaccine on HPV infection. Methods A case-control study method was used to retrospectively investigate the HPV infection status of 9246 women who received high-risk HPV infection examination in the outpatient department of Shiyan people's Hospital of Hubei from January 2018 to December 2018. The second-generation hybrid capture method and colposcopy examination were used to diagnose. Using a 1:1 matching method, the uninfected individuals who were examined during the same period were taken as the control group, and the confirmed infected group was taken as the case group, and the differences in the vaccination rates of the bivalent HPV vaccine between the two groups were compared. At the same time, the case group was divided into two groups according to the vaccinated and unvaccinated groups and followed up. The events ranged from 24 to 36 months. The incidence of persistent HPV infection, cervical intraepithelial neoplasia (CIN) and cervical cancer were counted to understand Protective effect of bivalent HPV vaccination against HPV infection in a high-risk female population. Results A total of 1 632 cases (17.65%) of 9 246 women were screened positive for high-risk HPV infection. Chi-square results showed that the HPV positive infection rate of rural women (32.84%) was lower than that of urban women (67.16%). , Marital status also has a certain influence on HPV infection. Among the 1632 cases of HPV positive infection, 629 cases (38.54%) were vaccinated with bivalent HPV vaccine, and 1003 cases (61.46%) were not vaccinated with bivalent HPV vaccine. During the follow-up period of 24-36 months, the vaccination group finally obtained follow-up data of 584 cases due to unwillingness to cooperate (18 cases), unable to conduct research due to organic changes (24 cases), and mental disorders (3 cases), with a loss to follow-up rate of 7.15 cases. %; In the unvaccinated group, 949 cases of follow-up data were finally obtained due to change of residence (32 cases), low degree of cooperation (20 cases) and psychological factors (2 cases), and the loss to follow-up rate was 5.38%. The results after follow-up showed that the persistent HPV infection rate in the bivalent HPV vaccination group, the positive rate of high-risk HPV infection at the last follow-up, the cumulative incidence of CIN1 during the follow-up period, the cumulative incidence of CIN2+ during the follow-up period, the incidence of CIN1 at the last follow-up, and the incidence of CIN2+ at the last follow-up. and cervical cancer incidence rates were 3.07%, 0.82%, 1.84%, 1.02%, 0.82%, 0.20%, and 0.00%, respectively, and the bivalent HPV unvaccinated groups were 12.91%, 15.52%, 7.14%, 4.40%, and 3.02%, respectively. , 1.37% and 0.27%. Persistent HPV infection rate, positive rate of high-risk HPV infection at last follow-up, cumulative incidence of CIN1 during follow-up, cumulative incidence of CIN2+ during follow-up, incidence of CIN1 at last follow-up, and incidence of CIN2+ at last follow-up were significantly lower in bivalent HPV vaccination group in the control group (P<0.05). Conclusion Bivalent HPV vaccination has an important protective effect on HPV persistent infection, cervical lesions and cervical cancer in high-risk women.
