Objective:To examine the plasma soluble interleukin 2 receptor (sIL-2R)and the expression of IFN-γR in helper T (Th)cells in peripheral blood of patients with recurrent oral ulcer(ROU).Methods:The peripheral blood was obtained from 21 pa-tients in active stage of ROU and 21 healthy controls.Flow cytometry was used to detect the quantity of IFN-γR in CD +4 T cells,ELISA was used to detect the level of sIL-2R.Results:The expression of IFN-γR in CD +4 T cells and sIL-2R content in plasma of the patients with ROU were significantly higher than those in the healthy controls(P <0.05).Conclusion:Over expression of IFN-γR in CD +4 T cells and sIL-2R in peripheral blood may be related to the genesis of ROU.

Objective:To investigate the expression of LAIR-1 on Treg cells and TGF-βin the peripheral blood of patients with oral lichen planus(OLP).Methods:The peripheral blood was obtained from 22 OLP patients and 22 healthy controls.Flow cytometry was used to evaluate the proportion of LAIR-1 on CD4 +Foxp3 +Treg cells,and the level of TGF-βwas measured by ELISA.Results:In the peripheral blood of OLP patients,the proportion of LAIR-1 on CD4 +Foxp3 +Treg cells and TGF-βcontent were significantly higher than those of the healthy controls(P ＜0.05),The proportion of LAIR-1 on CD4 +Foxp3 +Treg cells was positively correlated with the level of TGF-β(r =0.43,P ＜0.05).Conclusion:The high expression of LAIR-1 on CD4 +Foxp3 +Treg cells and TGF-βin the pe-ripheral blood of OLP patients may be responsible for the pathogenesis of OLP.

AIM:To investigate the correlation between severity of diabetic retinopathy(DR)and corneal sub-basal nerve plexus(SNP)changes. METHODS: There were 132 patients with 132 eyes in type 2 diabetes(T2DM)and 80 patients with 80 eyes in age-related cataract selected in our hospital from January 2018 to May 2021, among them, there were 52 non-diabetic retinopathy(NDR)patients with 52 eyes, 40 non proliferative diabetic retinopathy(NPDR)patients with 40 eyes and 40 proliferative diabetic retinopathy(PDR)patients with 40 eyes in T2DM. The general data and corneal laser scanning confocal microscopy were analyzed. Spearman rank correlation analysis was used to evaluate the correlation between DR clinical stage and nerve fiber length. RESULTS: There were no differences in gender and age comparisons among 4 groups(P>0.05). The diabetes duration in PDR group was significantly longer than NPDR group and NDR group(P<0.05). The diabetes duration in NPDR group was significantly longer than NDR group(P<0.05). The levels of fasting blood glucose and glycosylated hemoglobin in age-related cataract group were significantly lower than other three groups(P<0.05). The best corrected visual acuity in PDR group was significantly lower than NPDR group and NDR group(P<0.05). The best corrected visual acuity in NPDR group was significantly lower than NDR group(P<0.05). The length of nerve fibers in age-related cataract group was significantly higher than NDR group, NPDR group and PDR group(P<0.05). The length of nerve fibers in PDR group was significantly shorter than NPDR group(P<0.05). Spearman rank correlation analysis showed that there was a negative correlation between DR stage and nerve fiber length(rs=-0.347, P<0.001).CONCLUSION: There was a correlation between the severity of DR and the changes of corneal SNP. The length of nerve fibers in patients with PDR was significantly shorter than patients with NPDR; Both PDR and NPDR have a loss of neural structure and should pay attention to the evaluation and treatment of ocular surface lesions in the treatment of T2DM fundus lesions.

Objective To investigate the risk of Anisakis infections among high-risk populations along the coastal areas of Jiangsu Province, so as to develop the strategy for the prevention and control of anisakiasis in the province. Methods Three counties along the coastal areas of Jiangsu Province were selected as the study sites in 2018, including Rudong County in Nantong City, Haizhou District in Lianyungang City and Dongtai City in Yancheng City. The knowledge, attitude and practice (KAP) of anisakiasis prevention and control, and the prevalence of serum specific IgG antibody against Anisakis were investigated among high-risk populations among these three study sites, including fishermen, fish seller and people who liked eating fresh and live marine fish. Factors affecting the prevalence of the specific IgG antibody against Anisakis were identified using a multiple logistic regression model. In addition, Anisakis larvae infections were detected in fresh and live marine fish samples collected from local markets, and the prevalence and intensity of Anisakis infections were estimated. Results A total of 625 high-risk populations were investigated, including 349 men (55.8%). Only 13.0% of the subjects heard about anisakiasis, and a low awareness rate of anisakiasis prevention and control knowledge was seen among these three types of high-risk populations. There were 21.6% of the subjects eating raw or half-cooked marine fish, 5.8% eating undercooked marine fish, 3.2% presenting vomiting, nausea and diarrhea after eating marine fish, 5.1% developing systemic allergic symptoms, and 65.6% using the same chopping board for raw and cooked food. The sero-prevalence of the anti-Anisakis IgG antibody was 7.0% among the study subjects. Multiple logistic regression analysis identified education level [OR = 0.687, 95% CI (0.478, 0.987)] and development of systemic allergic symptoms [OR = 4.641, 95% CI(1.411, 15.268)]as factors affecting the positive anti-Anisakis IgG antibody among the study subjects. Among 494 fresh and live marine fish detected, the prevalence and intensity of Anisakis larvae infection was 64.0% and 8.1 larvae per fish, with high prevalence seen in Trichiurus haumela and Pneumatophorus japonicas. Conclusions The awareness of anisakiasis prevention and control knowledge is low among the high-risk populations living along the coastal areas of Jiangsu Province, and there are high-risk behaviors, such as eating raw or half-cooked food, using the same chopping board for raw and cooked food. In addition, the prevalence of Anisakis infections is high in the marine fish in these areas. Therefore, the health education and health promotion for anisakiasis prevention and control should be intensified.

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ²=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ²=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.
