Objective; To study estrogen receptor gene Xbal and Pvu Ⅱ polymorphisms in patients with aggressive periodontitis (AgP). Methods; Xbal and Pvu Ⅱ DNA was extracted by Chelex-100 and amplified by PCR from buccal swabs of 48 cases of AgP patients and 60 normal controls. The PCR products were analyzed by polymerase chain reaction linked fragment length polymorphism (PCR-RFLP) assay. Results: There were significant differences of the distribution of Xba I genotype between AgP group and control group, female AgP group and female control group, male AgP group and male control group(P<0.05). There was no difference of Pvu D genotype distribution between patient group and control group (P>0.05). Multivariate Logistic Regression Analysis showed that male group was less susceptible to AgP than female group(OR =0. 352), the older was less susceptible to AgP than the younger(OR =0.950), and the xxXx genotype was less susceptible to AgP than XX genotype [OR(Xx) =0.224, OR(xx) = 0.678). Conclusion: Specific relationship is found between the susceptibility of AgP and the ER gene-Xbal polymorphism. People with XX genotype is more susceptive to AgP than xx, Xx genotypes.

Objective To evaluate the clinical efficacy and safety of combined ozone hydrotherapy for the treatment of atopic dermatitis(AD). Methods A total of 60 patients with moderate or severe AD aged from 6 to 65 years were enrolled, and randomly and equally divided into a test group and a control group. Both the two groups were treated with oral levocetirizine capsules 5 mg once a day, topical tacrolimus ointment twice a day, and topical moisturizers. The test group was additionally treated with ozone hydrotherapy 3- 5 times every week. The treatment lasted 2 weeks. The severity scoring of atopic dermatitis (SCORAD) score, visual analog scale (VAS) score, dermatology life quality index (DLQI) or children′s dermatology life quality index (CDLQI) score were assessed before and after the treatment, and compared between the two groups. Enzyme?linked immunosorbent assay(ELISA) was performed to measure the levels of interleukin?4(IL?4)and nerve growth factor(NGF)in peripheral blood from the patients before and after the treatment. Results After 2?week treatment, the SCORAD scores, VAS scores and DLQI/CDLQI scores significantly decreased from 42.13 ± 16.03, 7.14 ± 2.12 and 14.92 ± 5.94 before the treatment to 27.3 ± 11.01, 2.23 ± 1.31 and 9.69 ± 4.17 respectively in the test group(all P<0.05), and from 43.36 ± 17.78, 6.45 ± 1.29 and 15.15 ± 5.40 to 39.65 ± 16.67, 3.32 ± 0.87 and 12.84 ± 5.37 respectively in the control group(all P<0.05). In addition, all the three scores were significantly lower in the test group than in the control group after 2?week treatment(all P<0.05). A significant decline was also observed in the levels of IL?4 and NGF in peripheral blood in the two groups at the end of the treatment compared with those at baseline(all P<0.05), and the magnitude of decline in IL?4 levels was significantly higher in the test group than in the control group(t=8.57, P<0.05), while that in NGF levels was insignificantly different between the two groups(t=9.51, P>0.05). Conclusion Combined ozone hydrotherapy can effectively and safely improve the condition of patients with AD, likely by decreasing the levels of IL?4 in peripheral blood.

The Mean±SD and M ( Q1, Q3) were used for quantitative data for statistical description, and the rate, composition or relative ratio of qualitative data were used for statistical description. Results:A total of 23 clinical trials meeting the requirements were screened, among which 19 were biological products included in nine phase Ⅲ clinical trials. Among the four chemical drugs, two were phase Ⅱ clinical trials. One of the clinical trials on AS adopted the 1966 New York classification criteria, accounting for 4%. Nineteen of the trials adopted the1984 New York classification criteria, accounting for 83%. Three other trials adopted unspecified classification criteria, accounting for 13%. In one of these clinical trials, the age of patients included was older than 16 years old, 9 trials were 18 to 65 years old, 6 were 18 years old but without upper limit. In the definition of active AS, 19 trials took BASDAI≥4 as the cut-off value for active disease, and BASDAI, total back pain, spinal pain and morning stiffness were regarded as active disease in 4.Conclusion:The number of dosestic AS clinical trial projects continnes to rise. The 1984 classification criteria is adopted as the classification criteria in clinical trials. The minimum age in the inclusion criteria is 18 years old, there is no upper limit in age for inclusion. Disease activity can be evaluated by BASDAI score, combined with comprehensive indicators such as night-time back pain, global spinal pain and morning stiffness.

Objective:To investigate the indoor radon concentrations and to analyze their seasonal variations in urban and rural residential dwellings in Ningxia province.Methods:From March 2022 to March 2023, based on the administrative region division and population distribution in Ningxia, a total of 143 typical residential dwellings, including 82 urban houses and 61 rural houses, were selected to measure indoor radon concentration by CR-39 solid nuclear track detectors for 1 year in Ningxia, with detectors changed every 3 months.Results:The annual average indoor radon concentration in Ningxia was 88 Bq/m 3, range 39-226 Bq/m 3. The annual average indoor radon concentration was below 100 Bq/m 3 for 69.9% of the measured dwellings, and below 300 Bq/m 3 for all of surveyed dwellings. Indoor radon concentrations in rural areas were much higher than those in urban areas ( Z=5.85, P<0.05). Indoor radon concentration varied significantly with the seasons, higher in autumn and winter, but lower in spring and summer, in total ( χ2=63.97, P<0.05), urban ( χ2=24.74, P<0.05), and rural ( χ2=43.15, P<0.05). Conclusion:The annual average indoor radon concentrations in all the measured dwellings are below the reference level of 300 Bq/m 3 recommended by Indoor Air Quality Standard (GB/T 18883-2022) in China.
