Objective:To learn about the changing trend of iodine deficiency disorders (IDD) and the iodine nutrition level of key populations in Fuzhou.Methods:From March 2017 to October 2019, a cross-sectional survey method was used to carry out IDD monitoring among key populations in 12 counties (cities, districts) of Fuzhou. In each county (city, district), one township/street was selected from five directions: East, West, South, North and Middle. Forty non-boarding children aged 8-10 (age balanced, half male and half female) from one primary school and 20 pregnant women in each township/street were selected as the survey subjects. The edible salt samples and instant urine samples of children and pregnant women were collected to detect the contents of salt iodine and urinary iodine; the thyroid volume of children was measured by B-ultrasound, and the goiter rate was calculated.Results:From 2017 to 2019, a total of 7 479 edible salt samples were collected from children's homes, and the median salt iodine was 23.40 mg/kg, the coverage rate of iodized salt was 94.06% (7 035/7 479), the qualified rate of iodized salt was 97.70% (6 873/7 035), and the consumption rate of qualified iodized salt was 91.90% (6 873/7 479). A total of 3 602 edible salt samples were collected from pregnant women's homes, and the median salt iodine was 23.69 mg/kg, the coverage rate of iodized salt was 94.73% (3 412/3 602), the qualified rate of iodized salt was 97.66% (3 332/3 412), and the consumption rate of qualified iodized salt was 92.50% (3 332/3 602). A total of 7 479 urine samples were collected from children, and the median urinary iodine was 172.70 μg/L. A total of 3 602 urine samples were collected from pregnant women, and the median urinary iodine was 131.21 μg/L. A total of 7 479 cases of thyroid gland in children were examined, including 89 cases of goiter, and the goiter rate was 1.19%.Conclusions:The consumption rate of qualified iodized salt ( > 90%) of key populations, urinary iodine (100-< 200 μg/L) and goiter rate ( < 5%) of children in Fuzhou are all in line with the national standard for elimination of IDD, but pregnant women are at risk of iodine deficiency (urinary iodine < 150 μg/L).

Objective:To investigate the iodine nutrition status of key population in Fuzhou City, and to provide scientific basis for adjusting intervention strategies.Methods:From March to October 2021, a survey was conducted on iodine nutrition status of key population in 12 counties (cities, districts) of Fuzhou City. Each county (city, district) was divided into 5 sampling areas according to the east, west, south, north and middle directions. One township (street) was selected from each area, and 40 non-boarding children aged 8 - 10 (age balanced, half male and half female) from one primary school and 20 pregnant women (early, middle and late pregnancy balanced) were selected as survey subjects. Household salt samples and random urine samples were collected, and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry, respectively. Children's thyroid volume was measured by B-ultrasonography. At the same time, in cooperation with Fuzhou Maternal and Child Health Hospital, the thyroid stimulating hormone (TSH) testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results:A total of 2 400 children were monitored for salt iodine, urine iodine and goiter. The median salt iodine was 24.40 mg/kg, with an iodine salt coverage rate of 93.04% (2 233/2 400), a qualified rate of iodized salt of 97.40% (2 175/2 233), and a consumption rate of qualified iodized salt of 90.62% (2 175/2 400). The median urine iodine was 181.47 μg/L. The rate of goiter was 1.04% (25/2 400). A total of 1 200 pregnant women were monitored for salt iodine and urine iodine. The median salt iodine was 24.10 mg/kg, the coverage rate of iodized salt was 91.08% (1 093/1 200), the qualified rate of iodized salt was 97.90% (1 070/1 093), and the consumption rate of qualified iodized salt was 89.17% (1 070/1 200). The median urine iodine was 128.10 μg/L. The median TSH level in the heel blood of 14 242 newborns was 3.38 mU/L, and the proportion of TSH level > 5 mU/L was 30.96% (4 410/14 242).Conclusions:In 2021, children in Fuzhou City are at an appropriate level of iodine, but pregnant women are insufficient of iodine. We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization, provide health education for pregnant women, and strengthen monitoring of TSH level in newborns.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

The pandemic of coronavirus disease 2019 (COVID-19) has had a serious impact on global health. COVID-19 vaccines may be one of the most effective measure to end the pandemic. High infection risk and higher serious incident and mortality rates have been shown in cancer patients with COVID-19. Therefore, cancer patients should be the priority group for COVID-19 prevention. Until now, data of COVID-19 vaccination for cancer patients is lacking. We review the interim data of safety and immune-efficacy of COVID-19 vaccination in cancer patients based on the latest studies. Due to the complicated immune systems of cancer patients caused by the malignancy and anticancer treatments, we proposed preliminary specific COVID-19 vaccination recommendations for cancer patients with different anticancer treatments and at different stages of the disease. Preventing COVID-19 with vaccinations for cancer patients is crucial, and we call for more large-scale clinical trials and real-world studies, for further COVID-19 vaccination recommendations development.

Rho-associated kinases (ROCKs) are serine-threonine protein kinases that act downstream of small Rho GTPases to regulate the dynamics of the actin cytoskeleton. Two ROCK isoforms (ROCK1 and ROCK2) are expressed in the mammalian central nervous system. Although ROCK activity has been implicated in synapse formation, whether the distinct ROCK isoforms have different roles in synapse formation and function in vivo is not clear. Here, we used a genetic approach to address this long-standing question. Both Rock1 and Rock2 mice had impaired glutamatergic transmission, reduced spine density, and fewer excitatory synapses in hippocampal CA1 pyramidal neurons. In addition, both Rock1 and Rock2 mice showed deficits in long-term potentiation at hippocampal CA1 synapses and were impaired in spatial learning and memory based on the water maze and contextual fear conditioning tests. However, the spine morphology of CA1 pyramidal neurons was altered only in Rock2 but not Rock1 mice. In this study we compared the roles of ROCK1 and ROCK2 in synapse formation and function in vivo for the first time. Our results provide a better understanding of the functions of distinct ROCK isoforms in synapse formation and function.
