Purpose To explore the clinical application value of dual-layer detector spectral CT combined with half volume contrast agent in detecting the liver metastases in portal vein phase.Materials and Methods Ninety-six patients with liver metastases diagnosed by liver enhanced CT in the First Affiliated Hospital of Fujian Medical University from November 2021 to June 2022 were prospectively studied.They were randomly divided into two groups by using the contrast agent administration calculation method based on body surface area.The conventional polyenergetic image(CI)of patients in the conventional contrast agent group(48 cases with 18.6 gI/m2 body surface area iodine contrast agent)was constructed in the portal vein phase,and the 40-70 keV(5 kiloelectron voltage)virtual monoenergetic imaging(VMI)was reconstructed for patients in the semi contrast agent dose group(48 case with 9.3 gI/m2 body surface area iodine contrast agent).The image noise,CT value and contrast noise ratio in the two groups were measured and compared.Besides,the image quality was scored with a 5-point method,and the consistency of subjective scores between two radiologists were evaluated.Results The VMI noise at 40-70 keV was(10.26±1.38)Hu,(9.59±1.35)Hu,(9.15±1.31)Hu,(8.80±1.32)Hu,(8.58±1.31)Hu,(8.40±1.31)Hu and(8.27±1.33)Hu;while the CI noise was(10.86±1.13)Hu.It revealed that the VMI noise at 45-70 keV was lower than the CI noise(t=-3.885,-5.343,-6.449,-7.180,-7.756 and-8.132,P<0.001).There was no significant difference between VMI and CI noises at 40 keV(t=-1.800,P>0.05).With the decrease of energy level,CT value of normal liver parenchyma,and contrast noise ratio values of liver parenchyma and liver metastases gradually increased,at the 40 keV level,the values of which were(148.31±21.34)Hu,8.81±2.83 and 8.18±2.85;at the 45 keV level,the values were(130.10±16.95)Hu,7.66±2.46 and 7.48±2.55;at the 50 keV level,the values were(116.19±13.55)Hu,6.60±2.08 and 55.40±13.77,reaching the highest at 40 keV level,while the CI values were(118.02±7.02)Hu,5.69±1.11 and 5.77±1.41.Therefore,the value of 40 keV and 45 keV VMI was significantly higher than CI(t=3.804,4.883,4.462,all P<0.05;t=2.854,3.465,3.378,all P<0.05),respectively.There was no significant difference between 50 keV VMI and CI(t=-0.612,1.739,2.208,P>0.05).The subjective score in the overall quality of VMI images was higher than that of CI at 40-50 keV(t=9.628,7.508,3.514,P<0.05).The subjective scores of the two physicians were good consistent among image contrast,image noise and overall image quality(Kappa=0.766,0.749 and 0.661,P<0.05),respectively.Conclusion VMI at 40-50 keV can provide better image quality and display ability of liver metastases than CI images at portal vein phase with a 50%reduction in contrast agent dose.

Objective:To explore the antipyretic effect and partial mechanism of the pushing Tianheshui manipulation on lipopolysaccharide(LPS)-induced fever in young New Zealand rabbits. Methods:Thirty 50-day-old New Zealand rabbits were randomly assigned to five groups,including a normal group,a model group,a Tuina(Chinese therapeutic massage)group,a Tuina control group,and a drug group,with 6 rabbits in each group.All groups except for the normal group received LPS injections through the marginal ear vein to induce fever.One hour post-modeling,the Tuina and Tuina control groups received pushing Tianheshui manipulation and pushing manipulation on the medial middle of the hind limbs,respectively,administered every hour for a total of 3 interventions.The drug group was given acetaminophen oral liquid via gavage.Anal temperature was recorded every 30 min for 4.0 h to monitor temperature changes among groups.At 4.0 h post-modeling,hypothalamus samples from each group were analyzed using Western blotting(WB)and real-time quantitative polymerase chain reaction(RT-qPCR)to measure the relative expression levels of α-melanocyte-stimulating hormone(α-MSH),melanocortin 4 receptor(MC4R),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),nuclear factor-κB p65(NF-κB p65),and interleukin(IL)-1β proteins and their mRNAs. Results:Compared to the model group,the Tuina group showed a significant reduction in the anal temperature from 3.5 h to 4.0 h post-modeling(P<0.05).The Tuina control group did not show a significant temperature reduction from 0.5 h to 4.0 h post-modeling(P>0.05).The drug group exhibited a significant temperature reduction from 1.5 h to 4.0 h post-modeling(P<0.05).At 4.0 h post-modeling,compared to the model group,the Tuina group showed significantly increased relative expression of α-MSH and MC4R proteins and mRNAs(P<0.05)and significantly decreased relative expression of cAMP,PKA,NF-κB p65,and IL-1β proteins and mRNAs in the hypothalamus tissue(P<0.05).No significant differences were observed in these parameters in the Tuina control group compared to the model group(P>0.05). Conclusion:Pushing Tianheshui manipulation demonstrated a significant antipyretic effect,potentially linked to point specificity.Its mechanism may involve the α-MSH-mediated cAMP/PKA/NF-κB pathway.

Objective:To investigate the effects of abdominal Tuina(Chinese therapeutic massage)on behavioral function,5-hydroxytryptamine 1A receptor(5-HT1AR),and synapsin-1(Syn1)in neonatal rats with hypoxic-ischemic brain injuries(HIBI). Methods:Forty healthy neonatal rats,born of 5 specific pathogen-free healthy pregnant rats,were randomly divided into a group for modeling(n=28)and a sham operation group(n=12)on the 7th day of birth.In the group for modeling,24 neonatal rats with HIBI successfully established by the Rice method were randomly divided into a model group(n=12)and an abdominal Tuina group(n=12).The abdominal Tuina group was given abdominal Tuina for 28 d from 24 h after modeling,and the other groups were put under the same conditions but without any treatments.Rats in each group were subjected to suspension tests on the 7th,14th,21st,and 28th days of intervention.After the intervention,the rat hippocampal tissue was collected and stained with hematoxylin-eosin to observe the pathological changes in the rat hippocampal CA1 region.The 5-HT1AR expression in rat hippocampal CA1 region was detected by immune-histochemistry.The Syn1 expression in rat hippocampus was measured by Western blotting method. Results:The cells were disordered,and edema and necrosis appeared in the hippocampal CA1 region of the model group.Cell arrangement was clear,and edema was improved obviously in the hippocampal CA1 region of the abdominal Tuina group.Compared with the sham operation group,the suspension test scores,the number of 5-HT1AR positive cells,and Syn1 protein expression in the hippocampus decreased significantly in the model group after 21 d and 28 d of interventions(P<0.05).Compared with the model group,the suspension test scores,the number of 5-HT1AR positive cells,and Syn1 protein expression increased significantly in the abdominal Tuina group after 21 d and 28 d of interventions(P<0.05). Conclusion:Abdominal Tuina improves the behavioral function of upper limbs and up-regulates the expression levels of 5-HT1AR and Syn1 in the hippocampus of neonatal HIBI rats.

OBJECTIVES: During the coronavirus disease 2019 (COVID-19) pandemic, a growing prevalence of racial and ethnic discrimination occurred when many Americans struggled to maintain healthy lifestyles. This study investigated the associations of racial and ethnic discrimination with changes in exercise and screen time during the pandemic in the United States. METHODS: We included 2,613 adults who self-identified as non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, or Hispanic from the Health, Ethnicity, and Pandemic study, a cross-sectional survey conducted among a nationally representative sample of United States adults between October and November 2020. We assessed self-reported racial and ethnic discrimination by measuring COVID-19-related racial and ethnic bias and examined its associations with changes in exercise and screen time using multivariable logistic regression models. We analyzed data between September 2021 and March 2022. RESULTS: COVID-19-related racial and ethnic bias was associated with decreased exercise time among non-Hispanic Asian (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.13 to 1.89) and Hispanic people (OR, 1.91; 95% CI, 1.32 to 2.77), and with increased screen time among non-Hispanic Black people (OR, 1.94; 95% CI, 1.33 to 2.85), adjusting for age, sex, education, marital status, annual household income, insurance, and employment status. CONCLUSIONS Racial and ethnic discrimination may have adversely influenced exercise and screen time changes among racial and ethnic minorities during the COVID-19 pandemic in the United States. Further studies are needed to investigate the mechanisms through which racial and ethnic discrimination can impact lifestyles and to develop potential strategies to address racial and ethnic discrimination as a barrier to healthy lifestyles.

ObjectiveTo determine the incidence and characteristics of adverse events following immunization （AEFI） in 2016‒2020 in Dazu District of Chongqing， and evaluate the AEFI surveillance information system and provide scientific evidence for vaccine safety. MethodsDescriptive epidemiological analysis was performed on the cases collected by the AEFI surveillance system. Incidence and coverage of AEFI were then presented. ResultsA total of 319 AEFI cases were reported in 2016‒2020. Reported incidence of AEFI was determined to be 24.64/10⁵ doses. The proportion of timely reporting AEFI within 48 hours was 94.04% and that of timely investigation within 48 hours was 98.41%. The proportion of completing the AEFI survey was 100.00% and that of AEFI classification was 99.69%. The male to female ratio was 1.28∶1. Majority of the AEFI cases were less than 1 year old （64.26%， 205/319）， from April to September （68.97%， 220/319）， and reported at 0‒1 day post-immunization （89.34%， 285/319）. Moreover， the reported incidence differed significantly between time periods （χ²=32.481，P<0.05） and time intervals from vaccination to occurrence of AEFI （χ²=961.408， P<0.05）. Coverage of reporting AEFI at county level reached 100％. In addition， non-severe AEFI cases accounted for 98.43% （314/319） and no death case was reported. General events， such as fever， redness， and scleroma， accounted for 80.56% （257/319）， whereas rare adverse events accounted for 15.99% （51/319）. The reported incidence of NIP vaccines was highest in the diphtheria tetanus acellular pertussis combined vaccine， followed by measles and rubella combined attenuated vaccine and diphtheria tetanus combined vaccine. Clinical diagnosis of rare adverse events was mainly allergic rashes. ConclusionThe AEFI surveillance information system in Dazu District of Chongqing achieves efficient monitoring of AEFI. It has proven that the vaccines are generally safe and immunization strategies may be continuously implemented. Furthermore， the sensitivity of AEFI surveillance should be improved through multiple approaches.

Objective:To explore the effect of abdominal massage on the behavior of rats with neonatal hypoxia-ischemia and its mechanism.Methods:7-day-old SD rats were made as the HIBD model by the classical method of RICE and then the HIBD model rats were divided into the abdominal massage group and model group according to the random number table method, with 12 rats in each group, and 12 rats were selected as the normal group. The abdominal massage group was given abdominal massage 24 hours after the modeling, and the intervention continued for 28 days. Rats in each group underwent a balance beam test on the 7th, 14th, 21st, and 28th day of the intervention. After the intervention, HE staining was applied to observe the morphological structure of the hippocampal CA1 region of the rats; Quantitative Real-time PCR method was used to measure the serotonin receptor (5-HTR1A) in the hippocampus. The expression of cAMP, PKA and CREB in the hippocampus were measured by immunohistochemistry, and the expression of SYP protein was measured by Western blotting.Results:After the intervention, the cells in the hippocampal CA1 area of the model group were diffusely distributed, the number of neurons reduced, and the condition of inflammatory edema appeared; the cells in hippocampal CA1 area of the abdominal massage group were arranged clearly, and the condition of inflammatory edema has significantly improved; on the 21st and 28th day of the intervention, the balance beam test scores in the abdominal massage group significantly decreased ( P<0.05), and the relative expression of 5-HTR1A mRNA (1.18±0.08 vs. 0.77±0.04) in the abdominal massage group significantly increased ( P<0.05). The expression of cAMP (0.32±0.02 vs. 0.31±0.01), PKA (0.32±0.02 vs. 0.29±0.01),CREB (0.31±0.02 vs. 0.28±0.01) and SYP in the abdominal massage group significantly increased ( P<0.05). Conclusion:Abdominal massage could improve the behavior of neonatal hypoxic-ischemic rats, which may play a role on nerve repair by regulating 5-HTR1A/cAMP/PKA signaling pathway.

Objective:To observe the effect of systematic graded rewarming measures on body temperature and prognosis of patients with moderate and severe trauma [revised trauma score (RTS) < 12] requiring emergency operation.Methods:A prospective randomized double-blind controlled study was conducted. From January 2020 to January 2021, 104 patients who underwent emergency trauma surgery in the Second Affiliated Hospital of Wenzhou Medical University were selected as the research object. According to random number table method, the patients were divided into traditional rewarming group and systematic graded rewarming group, with 52 cases in each group. Patients in traditional rewarming group (only record the body temperature without intervention, and start the rewarming process when the body temperature at any time was less than 36 ℃); the patients in the system graded rewarming group start the preventive measures as soon as they were admitted to the hospital, and record the body temperature. When the body temperature at any time was less than 36 ℃, start the graded rewarming process. Observe the rewarming effect, coagulation function, blood gas analysis and postoperative anesthesia recovery time of the two groups and final outcome.Results:With the extension of time, the body temperature of the two groups increased gradually. The body temperature of the systematic grade rewarming group was significantly higher than that of the traditional rewarming group at 2 hours after rewarming and at discharge (℃: 36.23±0.77 vs. 35.84±0.93 at 2 hours after rewarming, 36.54±0.87 vs. 35.82±0.92 at discharge, both P < 0.05). The incidence of subsequent hypothermia was significantly lower than that in the traditional rewarming group [7.7% (4/52) vs. 25.0% (13/52), P < 0.05]. The postoperative activated partial thromboplastin time (APTT) of the two groups was significantly shorter than that at admission (s: 35.74±8.05 vs. 45.55±28.02 in the systematic rewarming group, P < 0.05; 38.35±6.48 vs. 42.40±13.18 in the traditional rewarming group, P < 0.05); the intraoperative and postoperative pH values in the systematic rewarming group were significantly higher than those at admission (7.33±0.05, 7.36±0.06 vs. 7.30±0.07, both P < 0.05), while there was no significant difference between the intraoperative and postoperative pH values in the traditional rewarming group and those at admission (7.31±0.06, 7.33±0.06 vs. 7.31±0.05, both P > 0.05). The postoperative prothrombin time (PT) and anesthesia recovery time in the systematic graded rewarming group were significantly shorter than those in the traditional rewarming group [PT (s): 15.05±2.44 vs. 17.94±3.48, anesthesia recovery time (hours): 14.40±11.76 vs. 17.35±10.51, all P < 0.05], and the pH value was significantly higher than that in the traditional rewarming group (7.36±0.06 vs. 7.33±0.06, P < 0.05). The systematic graded rewarming group had higher improvement rate and lower disability rate than the traditional rewarming group (76.9% vs. 65.4% and 17.3% vs. 25.0%, both P < 0.05). Conclusion:Systematic graded rewarming measures can improve the hypothermia of emergency trauma patients who received surgery, reduce the incidence of subsequent hypothermia of trauma patients, shorten the time of postoperative resuscitation, improve the coagulation function and blood gas indexes, improve the treatment rate, and reduce the incidence of disability.

Objective:To explore human papillomavirus (HPV) infection status in 2 110 patients with cervical cancer in Henan province and analyze the main infection subtypes.Methods:A total of 2 110 patients with cervical cancer were detected for HPV subtypes by flow-through hybridization after PCR. The results were analyzed.Results:Among 2 110 patients with cervical cancer, 1 856 were detected to be HPV positive and the infection rate was 87.96%(95% CI: 86.57%-89.35%). The top six genotypes were HPV16, 58, 18, 52, 35 and 33. Single infection was the main type of infection in HPV positive cervical cancer patients (77.48%), and double infection was the second type infection(16.76%). The infection rate of HPV16 was 60.19%, occupying a predominant position in single or multiple infections. Among HPV positive cervical cancer patients, 1 599 cases were detected to be infected with high-risk subtypes and covered by nine-valence HPV vaccine, and the coverage rate reached 86.15% (1 599/1 856). Cervical cancer patients were mainly distributed in age group 40- years. The main HPV subtypes of cervical cancer patients were different among different age groups, but HPV16 subtype was in a predominant position in any age group. Conclusions:The main subtypes of HPV infection were HPV16, 58, 18, 52, 35 and 33 in cervical cancer patients in this study. The main infection type was single infection. There were more cervical cancer patients in age group 40- years.

Objective:To investigate the status of Corona Virus Disease 2019 (COVID-19) health literacy and associated factors in Inner Mongolia Autonomous Region.Methods:Based on the multi-stage stratified sampling method, the questionnaire survey of health literacy of COVID-19 were carried out in 55 599 local residents from12 prefecture-level cities of Inner Mongolia Autonomous Region between March 10 and 15, 2020. The questionnaire in details included not only knowledge, attitude and behavior, but also mental health, their scores were calculated using Decimal method. A ≥80% of the correct answer rate of the survey content was regarded as qualified for health literacy. There were 51 722 (93.0%) valid questionnaires, according to the ratio of medical staff to non-medical staff, 32 529 questionnaires were selected for analysis. The health literacy level was defined according to the proportion of qualified people.The credibility and availability of the questionnaires were evaluated by Cronbach′s α coefficient and KMO test. The associated factors were analyzed by Pearson χ 2 test and logistic regression. Results:In Inner Mongolia Autonomous Region, the whole level of health literacy of COVID-19 was 85.7%, and their scores were (26.30±2.48). Knowledge, attitude, and behavioral literacy levels were 61.6%, 95.6%, and 96.8%, respectively. Compared with the population of 15-25 years old, the health literacy level of 46-65 years old was the highest ( OR=2.00, 95% CI: 1.78-2.24). The health literacy level of medical staff group ( OR=2.54, 95% CI: 1.30-4.95) was far higher than the non-medical staff group; the population with college or above education level ( OR=10.22, 95% CI: 9.19-11.36) was significantly higher than the population with education level below college. The degree of anxiety was negatively correlated with education level. Conclusions:The health literacy level of COVID-19 in residents in Inner Mongolia Autonomous Region is relatively high, but the level of knowledge literacy needs to be improved. The main factors affecting the health literacy of COVID-19 among Inner Mongolia residents are age, occupation and education level.
