Objective To understand the prevalence of thyroid nodules of children lived in different water iodine areas in Cangzhou City. Methods From Oct. 2015 to Jan. 2017, 15 villages were selected as monitoring sites in Cangzhou,two drinking water samples were collected from each survey site(all had centralized water supply), and the water iodine content was determined. A total of 100 children aged 8 to 10 (half male and female) were examined for thyroid nodules, and at least 50 children (half male and half female) were selected to detect urinary iodine content. In the high iodine water counties, the monitoring sites of iodine salt was according to "National Iodine Deficiency Monitoring Program"; in the monitoring sites of iodine salt supplied counties, students in the monitored village were asked to detect urinary iodine and household salt samples were collected to monitor salt iodine. In the high iodine area, the salt iodine test was carried out by semi-quantitative method. In the non-high iodine area, the salt iodine content of the iodized salt monitoring sites was determined by direct titration, the salt iodine content of Chuan salt and other intensified edible salt was tested by arbitration(GB/T 13025.7-2012). Water iodine and urinary iodine were tested by arsenic and cerium catalytic spectrophotometry. Results Water iodine content was 28.2 - 1 128.0 μg/L in 15 villages; a total of 1 066 urine samples were examined, the median of uriary iodine in each village was 102.6-1 162.0 μg/L;a total of 1 575 children aged 8 to 10 years were examined,among them,125 cases of thyroid nodules were detected; thyroid nodules detection rate was 7.9%. The prevalence of male was 7.0% (61/871), and the prevalence of female was 9.1% (64/704), there was no significant difference in the detection rate of thyroid nodules between different sex (χ2=2.07,P>0.05); The detection rate of thyroid nodules were 4.5%(23/508),7.8%(4/51), 11.6%(59/507)in children with urinary iodine at the appropriate level (100 - <200 μg/L), the appropriate level (200 - < 300 μg/L) and iodine excess level (≥300 μg/L), the difference of thyroid nodules in children with different levels of urinary iodine detection rate was statistically significant (χ2=17.30, P < 0.01). The difference of prevalence of thyroid nodules in children aged 8 to 10 years with water iodine concentrations of 10 - < 100, 100 - < 300 and ≥300 μg/L was statistically significant[2.9%(13/448),7.9%(25/317), 10.7%(87/810),χ2=23.86,P<0.05].The patients with unilateral thyroid nodule accounted for 64.8% (81/125); the patients with multiple thyroid nodules counted for 58.4% (73/125), and 34.2%(13/38),69.0%(60/87)in areas with iodine content less than 300 μg/L and no less than 300 μg/L,the difference between the two was statistically significant (χ2= 13.14, P < 0.01). A total of 1 800 salt samples were collected from the high water iodine counties,of which 1 779 were iodine-free salt, the rate of iodine-free salt was 98.8%; a total of 190 salt samples were collected in student family, in the 4 iodized salt monitoring sites, the salt iodine median of resident's edible salt was 0.0 mg/kg. Conclusion The prevalence of thyroid nodules in children aged 8 - 10 years may be related to high water iodine in Cangzhou City; children with multiple thyroid nodules is also significantly higher in water iodine content greater than 300 μg/L areas.

Objective:To describe the characteristics and change trends of incidence, mortality and disease burden of acute myocardial infarction (AMI) in Qingdao from 2014 to 2020.Methods:We analyzed the incidence data of AMI retrieved from Qingdao Chronic Diseases Surveillance System. The average annual percent change (AAPC) of morbidity and mortality of AMI were evaluated by using Joinpoint log-linear regression model. Disability adjusted life year (DALY) was used to estimate disease burden of AMI in Qingdao.Results:A total of 70 491 AMI cases and 50 832 deaths of AMI occurred in Qingdao from 2014 to 2020. The age-standardized morbidity and mortality were 54.71/100 000 and 36.55/100 000, respectively. During 2014-2020, the AAPC of age-standardized morbidity was 2.86% (95% CI: 0.42%-5.35%), and 4.30% (95% CI: 1.24%-7.45%) in men and 0.78% (95% CI: -0.89%-2.47%) in women, respectively. The log-linear regression model showed that age-standardized morbidity in age groups 30-39, 40-49 years increased rapidly, with the AAPCs of 8.92% (95% CI: 2.23%-16.06%) and 6.32% (95% CI: 3.30%-9.44%), respectively. The trend was also observed in age groups 30-39, 40-49 and 50-59 years in men, with the AAPCs of 11.25% (95% CI: 3.54%-19.54%), 6.73% (95% CI: 2.63%-10.99%) and 6.72% (95% CI: 2.98%-10.60%), respectively. There was no significant change in age-standardized mortality. The DALY rate increased from 7.49/1 000 in 2014 to 8.61/1 000 in 2020, with the AAPC of 1.97% (95% CI: 0.36%-3.60%). Conclusions:The age-standardized morbidity of AMI in men increased in Qingdao, especially in those aged 30-49 years, while age-standardized mortality rate of AMI was relatively stable from 2014 to 2020. The burden of disease of AMI increased in both men and women.

Objective To understand the factors that affect the pulmonary rehabilitation behavior of elderly patients with lung cancer during the post-operative transitional period,and provide reference bases for formulating the pulmonary rehabilitation plan of elderly patients with lung cancer during the transitional period and improving the compliance of pulmonary rehabilitation.Methods Based on the capability,opportunity,and motivation-behavior model(COM-B model),12 elderly lung cancer patients who underwent surgery at a tertiary A tumor hospital in Tianjin from March to July 2022 were selected for semi-structured interviews using descriptive research methods and purposive sampling method.The data were analyzed using directed content analysis.Results The ability factors(physical strength and postoperative discomfort symptoms of the elderly limit lung rehabilitation exercise,lack of pulmonary rehabilitation knowledge and awareness of the importance of exercise in lung rehabilitation knowledge),opportunity factors(lack of grassroots medical and health services,limiting lung rehabilitation exercise;family and friends are important resources for promoting lung rehabilitation exercise;medical support is a guarantee for promoting lung rehabilitation exercise),motivational factors(high self-efficacy in exercise is the foundation for lung rehabilitation exercise,perception of lung rehabilitation effects increases motivation for lung rehabilitation exercise)and 7 sub themes were extracted.Conclusion There are certain obstacles and promoting factors in the transitional lung rehabilitation process for elderly lung cancer patients after surgery.It is necessary to improve their postoperative discomfort symptoms,increase their knowledge of lung rehabilitation,enhance their awareness of lung rehabilitation,face the social support role of family,friends,and medical staff,improve the infrastructure and lung rehabilitation system,increase community lung rehabilitation support,provide multi-channel high-quality lung rehabilitation resources,and promote the development of smart medical services,constructing a transitional lung rehabilitation strategy for elderly patients with lung cancer.

To investigate the safety and feasibility of gasless total endoscopic resection of deep lobe parotid gland tumors via a postauricular hairline plus temporal approach. The approach was designed as: a 4 to 5 cm main incision was designed at the postauricular hairline, and a 0.5 cm auxiliary incision was designed in the temporal hairline. The operating cavity was established with the assistance of a special retractor. "Anterograde" dissection of the facial nerve was performed throughout the procedure, along with partial or total gland removal of the tumor. All 16 operations were successfully completed without conversion to open surgery. During the operation, the trunk and branches of the facial nerve were completely preserved, the tumor was completely removed, and the incision healed. Six patients had mild facial paralysis after operation, and recovered completely after 3 to 6 months. There was no salivary fistula, Frey syndrome, infection, or other complications. The postoperative incision was concealed and the aesthetic effect was good. The postauricular hairline plus temporal approach gasless total endoscopic parotidectomy is safe and feasible. This technique can achieve the complete dissection of the total trunk to the branches of the facial nerve, and has good access to the tumors located in any part of the parotid gland region. On the basis of radical resection of the tumor, it achieves minimally invasive and aesthetic improvement.

OBJECTIVE: To explore the effectiveness of Nice knot technique for wound closure in Gustilo type ⅢA and ⅢB open tibial fractures. METHODS: A retrospective study was performed on 22 patients with Gustilo type ⅢA and ⅢB open tibial fractures, who underwent wound closure using the Nice knot technique and were admitted between June 2021 and June 2022. There were 15 males and 7 females. The age ranged from 18 to 67 years, with an average of 41.9 years. The causes of injury included traffic accident in 11 cases, falling from height in 7 cases, and heavy object injuries in 4 cases. Fractures were located on the left side in 9 cases and on the right side in 13 cases. And 9 cases were type ⅢA fractures and 13 were type ⅢB fractures according to Gustilo classification. All patients had extensive soft tissue injuries, and no vascular or neurological damage was observed. The time from injury to debridement was 3-8 hours (mean, 6.5 hours). The sizes of wounds before operation and at 2 weeks after operation were measured and wound healing rate at 2 weeks after operation were calculated. The wound healing time and wound healing grading were recorded. The Vancouver Scar Scale (VSS) score was used to assess the wound scar after wound healed and the excellent and good rate was calculated. RESULTS: The wound area was 21.0-180.0 cm ² (mean, 57.82 cm ²) before operation, and it was 1.2-27.0 cm ² (mean, 6.57 cm ²) at 2 weeks after operation. The wound healing rate at 2 weeks after operation was 76%-98% (mean, 88.6%). After operation, 2 cases needed to adjust Nice knot due to skin cutting and 1 case occurred soft tissue infection on the wound. The other patient's wounds healed. The average wound healing time was 27.8 days (range, 18-44 days). And the wound healing were grade A in 13 cases and grade B in 9 cases. VSS score was 2-9, with an average of 4.1; 10 cases were rated as excellent, 10 as good, and 2 as poor, with an excellent and good rate of 90.9%. All patients were followed up 9-24 months (mean, 14.6 months). During follow-up, no deep infection or osteomyelitis occurred. Two cases experienced fracture non-union, and were treated with compression fixation and bone grafting. The fractures of the other patients all healed, with a healing time of 85-190 days (mean, 148.2 days). CONCLUSION Nice knot technique can be used in wound closure of Gustilo type ⅢA and ⅢB open tibial fractures effectively, which is easy to operate.

Ischemic stroke is a severe disorder resulting from acute cerebral thrombosis. Here we demonstrated that post-ischemic treatment with ciclopirox olamine (CPX), a potent antifungal clinical drug, alleviated brain infarction, neurological deficits and brain edema in a classic rat model of ischemic stroke. Single dose post-ischemic administration of CPX provided a long-lasting neuroprotective effect, which can be further enhanced by multiple doses administration of CPX. CPX also effectively reversed ischemia-induced neuronal loss, glial activation as well as blood-brain barrier (BBB) damage. Employing quantitative phosphoproteomic analysis, 130 phosphosites in 122 proteins were identified to be significantly regulated by CPX treatment in oxygen glucose deprivation (OGD)-exposed SH-SY5Y cells, which revealed that phosphokinases and cell cycle-related phosphoproteins were largely influenced. Subsequently, we demonstrated that CPX markedly enhanced the AKT (protein kinase B, PKB/AKT) and GSK3 (glycogen synthase kinase 3) phosphorylation in OGD-exposed SH-SY5Y cells, and regulated the cell cycle progression and nitric oxide (NO) release in lipopolysaccharide (LPS)-induced BV-2 cells, which may contribute to its ameliorative effects against ischemia-associated neuronal death and microglial inflammation. Our study suggests that CPX could be a promising compound to reduce multiple ischemic injuries; however, further studies will be needed to clarify the molecular mechanisms involved.
