Objective: To investigate the epidemiological characteristics of rubella in Wuxi City, Jiangsu Province from 2015 to 2023, so as to provide the basis for rubella prevention and control. Methods: Data of rubella surveillance cases and laboratory tests were collected through the Chinese Measles Surveillance Information Report Management System. The temporal, regional and demographic distribution of confirmed rubella cases were analyzed using the descriptive epidemiological method. Results: A total of 2 167 rubella surveillance cases were reported in Wuxi City from 2015 to 2023, including 154 confirmed rubella cases, with an average annual reported incidence of 0.25/105. All the confirmed cases were laboratory-confirmed, and the positive rate of laboratory testing was 7.11%. The main clinical symptoms were rash (96.75%) and fever (86.36%). The incidence of rubella peaked in 2015 and 2019, with sporadic cases in other years. Rubella incidence exhibited a distinct seasonal pattern, and the prevalent months were from February to May. Xishan District and Huishan District had the higher reported incidences, at 0.44/105 and 0.42/105, respectively. There were 101 male confirmed rubella cases and 53 female cases, with a male-to-female ratio of 1.91∶1. The incidence was higher in males than in females (0.32/105 vs. 0.18/105, P<0.05). The majority of cases were aged 19 to <46 years, with 112 cases accounting for 72.73%. There were 43 workers (27.92%) and 27 housekeepers and unemployed individuals (17.53%). The rubella containing vaccine immunization rate among the confirmed rubella cases was 12.99%, which was lower than the 36.20% among the cases excluding measles and rubella (P<0.05). The majority of the individuals aged 19 years and above had unknown immunization histories. Conclusions The reported incidence of rubella in Wuxi City remained low from 2015 to 2023. The disease was prevalent in winter and spring, and the cases mainly distributed in Xishan District and Huishan District. Individuals aged 19 to <46 years, males and workers were key populations for prevention and control.

Objective:To investigate the clinical results of gasless endoscopic thyroidectomy via posterior chest-collarbone approach (GETPCA) compared with open neck surgery for papillary thyroid carcinoma (PTC) .Mthods:Retrospective analysis of PTC patients admitted to the Department of Thyroid and Breast Surgery of the Third Affiliated Hospital of Anhui Medical University from Jan. 2022 to Dec. 2023,and randomly divided into the open group and the lumbo-scopic group according to whether or not they had a requirement for an unmarked neck, in which the open group was n=100,and the lumbo-scopic group was n=67,with 39 male cases and 128 female cases. Clinicopathological characteristics, surgery-related indexes, postoperative complications, postoperative pain scores and postoperative cosmetic satisfaction were compared between the two groups.The t-test,Wilcoxon rank-sum test, χ2 test, consecutively corrected χ2 test, or Fisher’s exact probability method were used to compare the groups. Results:No recurrence was seen during the follow-up period,and none of the cases in the luminal group was open in the middle. The differences in age, body mass index BMI, gender, relative tumor location,preoperative TSH, T stage and N stage between the two groups were not statistically significant ( P>0.05) . The total operation time [ (121.07±39.80) min vs. (93.87±26.97) min]in the luminal group was greater than that in the open group,intraoperative bleeding was less than that in the open group, and the postoperative drainage flow[ (130.69±31.01) mL vs. (105.52±32.71) mL] was greater than that in the open group in the postoperative period of 72 h, and the difference was statistically significant ( P<0.001) .There was no statistical difference between the two groups in terms of 24-h postoperative drainage volume, number of central zone lymph node dissection, number of positive central zone lymph nodes,postoperative hospitalization days or total hospitalization cost ( P>0.05) .The number of cases of neck discomfort (3 cases vs.23 cases, P<0.001) and swallowing dysfunction (2 cases vs.20 cases, P=0.003) in the luminal group was smaller than that in the open group,and the difference was statistically significant.The difference in the incidence of bleeding,incision infection,seroma,temporary recurrent laryngeal nerve injury and temporary parathyroid gland injury between the two groups was also not statistically significant ( P>0.05) .The postoperative NRS on day 1 and postoperative NRS on day 3 of the luminal group were lower than those of the open group,and the difference was statistically significant ( P>0.05) ,while there was no statistically significant difference between the postoperative NRS on day 7,the postoperative NRS on month 1 and the postoperative NRS on month 3 ( P>0.05) .Cosmetic satisfaction at 6 months postoperatively was higher in the luminal group than in the open group,and the difference was statistically significant ( P<0.001) . Conclusion:GETPCA for the treatment of the PTC is safe and feasible,with satisfactory cosmetic results and reduction of neck discomfort and swallowing dysfunction,which is worthy of clinical popularization.

Due to the limitations of current anti-HBV therapies, the HBV core (HBc or HBcAg) protein assembly modulators (CpAMs) are believed to be potential anti-HBV agents. Therefore, discovering safe and efficient CpAMs is of great value. In this study, we established a HiBiT-based high-throughput screening system targeting HBc and screened novel CpAMs from an in-house marine chemicals library. A novel lead compound 8a, a derivative of the marine natural product naamidine J, has been successfully screened for potential anti-HBV activity. Bioactivity-driven synthesis was then conducted, and the structure‒activity relationship was analyzed, resulting in the discovery of the most effective compound 11a (IC₅₀ = 0.24 μmol/L). Furthermore, 11a was found to significantly inhibit HBV replication in multiple cell models and exhibit a synergistic effect with tenofovir disoproxil fumarate (TDF) and IFNa2 in vitro for anti-HBV activity. Treatment with 11a in a hydrodynamic-injection mouse model demonstrated significant anti-HBV activity without apparent hepatotoxicity. These findings suggest that the naamidine J derivative 11a could be used as the HBV core protein assembly modulator to develop safe and effective anti-HBV therapies.

Objective:To determine the predictive value of high-frequency ultrasonography for necrotizing enterocolitis (NEC) requiring surgical treatment in neonates.Methods:From January 2018 to December 2021, neonates diagnosed with NEC (Bell stage Ⅱ and above) in our hospital were retrospectively analyzed. The neonates were assigned into surgical group and non-surgical group according to the treatment. The following ultrasonography results were compared between the two groups: intestinal motility, gastrointestinal (GI) wall perfusion, pneumatosis intestinalis (PI), portal vein gas, peritoneal effusion translucency, depth of ascites fluid and GI wall thickness. Logistic regression was used to determine risk factors of surgical treatment for NEC. ROC curve was drawn to calculate the predictive value of combined and individual factors for NEC requiring surgical treatment.Results:A total of 40 neonates were enrolled, including 18 in the surgical group and 22 in the non-surgical group. No significant differences existed between the two groups in PI and depth of ascites fluid ( P>0.05). The surgical group had higher incidences of decreased intestinal motility, portal vein gas, reduced GI wall perfusion, poor peritoneal effusion translucency and thinner GI wall than the non-surgical group (all P<0.05). Logistic regression analysis showed that poor translucency of peritoneal effusion, thinning of GI wall, reduced GI wall perfusion and decreased intestinal motility were risk factors for surgical treatment of NEC. ROC curve showed that the cut-off value predicting surgical treatment based on GI wall thickness was 1.2 mm, with an area under the curve (AUC) of 0.746, sensitivity of 87.5% and specificity of 65.6%. The AUC of the combined factors predicting surgical treatment was 0.867, with sensitivity of 96.9% and specificity of 75.8%. Conclusions:Decreased intestinal motility and GI wall perfusion, thinning of GI wall and poor peritoneal effusion translucency on high-frequency ultrasonography have high predictive efficacy for the need of surgical treatment in the acute phase of NEC.

ObjectiveTo assess the implementation of insurance-based compensation for adverse reactions following immunization in Wuxi City，Jiangsu Province. MethodsData on basic insurance and supplementary insurance for adverse reactions following immunization from 2020 to 2022 in Wuxi City was collected， and a descriptive epidemiological method was used to analyze the data. ResultsA total of 2 272 cases were compensated for adverse reactions following immunization，with a total compensation amount of 5.255 9 million yuan， and an average of 2.3 thousand yuan per case. Basic insurance accounted for 0.62% of the total cases and 10.72% of the total compensation amount， while supplementary insurance accounted for 99.43% of the total cases and 89.28% of the total compensation amount. Compensation amounts for disability and third-degree damage in basic insurance accounted for 63.18% and 88.71%， respectively， while fourth-degree and lower damage in supplementary insurance accounted for 96.52%. The compensation rate for supplementary insurance was higher than that for basic insurance. The highest number of compensated cases was in the 0‒ year age group， and vaccines included in the Expanded Program on Immunization （EPI） accounted for the majority of the cases and compensation amounts， with a percentage of 70.11% and 73.84%， respectively. For basic insurance， the largest number of compensated cases involved the Bacillus Calmette-Guérin （BCG） vaccine. For supplementary insurance， the top three compensated cases for EPI vaccines were the measles-mumps-rubella （MMR） vaccine， the hepatitis B （HepB） vaccine， and the acellular diphtheria-tetanus-pertussis （DTaP） vaccine. For non-EPI vaccines， the top three compensated cases were the 13 valent pneumococcal polysaccharide conjugate （PPCV13） vaccine， the acellular DPT-inactivated poliovirus-haemophilus influenzae type b combined vaccine （DPT-IPV/Hib）， and enterovirus 71 （EV71） inactivated vaccine. In basic insurance， thrombocytopenic purpura and BCG local abscess both accounted for 21.43% of the cases， while in supplementary insurance， respiratory system diseases accounted for 77.47% of the cases. The time intervals from reporting to submission of compensation materials （<31 d） and from submission to payment of compensation （≤14 d） were 71.43% and 57.14% for basic insurance， and 90.22% and 86.23% for supplementary insurance， respectively. ConclusionThe commercial supplementary insurance for adverse reactions following immunization in Wuxi City has largely compensated for the limitations of basic insurance in terms of coverage and efficiency. It is recommended to further promote commercial compensation insurance for young children and strengthen the monitoring and regulation of commercial supplementary insurance compensation.

Summary: Structural nasal obstruction（SNO） is a series of diseases caused by congenital or acquired structural anatomical abnormalities of nasal airway and its surrounding tissues, which leads to increased nasal ventilation resistance. The effect of medication drugs for SNO is poor and surgical intervention is often needed. However, the abnormal structure of nasal airway is very complex, including the periphery of nasal airway, internal nasal airway, the front and rear of nasal airway and complex factors. These abnormal structures may interfere with the nasal airflow mechanics by changing the nasal ventilation volume and disrupting the symmetry of the bilateral nasal cavity, and finally lead to subjective feeling of nasal obstruction. In addition, the structure of nasal airway has plasticity. After the abnormal structure appears, the corresponding compensation of nasal airway can occur to ensure normal nasal ventilation and bilateral nasal cavity symmetry. Therefore, the SNO is the result of the failure of nasal airway remodeling after the appearance of abnormal structures. The etiology of SNO is complex, involving original structural abnormalities, nasal symmetry changing and nasal airway structure remodeling. Therefore, accurate identification of the main factors leading to SNO is the vitalpremise of making personalized nasal ventilation surgery.
