ABSTRACT
According to the extracorporeal life support(ECLS)registry report,the use of extracorporeal membrane oxygenation(ECMO)in neonates with severe respiratory failure reached its peak in 1992.With the emergence of new respiratory support methods such as nitric oxide,pulmonary surfactant,and high-frequency ventilation,the number of neonates with ECMO for respiratory support decreased gradually,maintaining at about 1000 cases per year.However,it also means that the neonates who need ECMO support will be in a more severe condition,which requires higher requirements for clinicians.In order to further standardize the technique of neonatal extracorporeal life support,the Extracorporeal Life Support Organization(ELSO)published the guidelines for neonatal respiratory failure in 2020.The guidelines provide suggestions on the technology,patient management and complications during ECMO.This article mainly interprets the patient selection,support mode,technical considerations,management and complications during ECMO.

ABSTRACT
Objective@#To explore incidence trend of hepatitis C in Chifeng City, Inner Mongolia Autonomous Region from 2008 to 2022, so as to provide the basis for formulating prevention and control measures for hepatitis C.@*Methods@#Data of reported hepatitis C cases in Chifeng City from 2008 to 2022 was collected through the Infectious Disease Information Reporting Management System. Trends in incidence of hepatitis C were analyzed using annual percent change (APC) and average annual percent change (AAPC). Impact of age, period and birth cohort on the risk of developing hepatitis C were analyzed by an age-period-cohort model.@*Results@#The annual average reported incidence rate of hepatitis C in Chifeng City was 59.13/105 from 2008 to 2022. The incidence showed an upward trend from 2008 to 2018 (APC=9.405%, P<0.05) and a downward trend from 2018 to 2022 (APC=-17.475%, P<0.05), but the overall trend was not statistically significant (AAPC=0.937%, P>0.05). The age-period-cohort model analysis showed that the incidence risks of hepatitis C in the residents aged 0 to 4 years and 45 to 84 years were higher than those in the residents aged 40 to 44 years (the control group). The incidence risk of hepatitis C increased with age from 40 to 79 years. Compared with 2008-2012, the incidence risk of hepatitis C showed an increasing trend followed by a decline in 2008-2022. The incidence risk was higher in 2013-2017 and lower in 2018-2022 than in 2008-2012. The incidence risk of hepatitis C showed an increasing trend followed by a decreasing trend by using the birth cohort from 1968 to 1972 as the control. The birth cohort from 1953 to 1977 had a higher incidence risk of hepatitis C than other birth cohorts.@*Conclusions@#The overall incidence of hepatitis C in Chifeng City from 2008 to 2022 appeared a tendency towards a decline, and the incidence risk increased with age. Screening and health education for the elderly and high-risk birth cohorts should be strengthened.
ABSTRACT
ObjectiveIn recent years, with the intensification of environmental issues and the depletion of ozone layer, incidence of skin tumors has also significantly increased, becoming one of the major threats to people’s lives and health. However, due to factors such as high concealment in the early stage of skin tumors, unclear symptoms, and large human skin area, most cases are detected in the middle to late stage. Early detection plays a crucial role in postoperative survival of skin tumors, which can significantly improve the treatment and survival rates of patients. We proposed a rapid non-invasive electrical impedance detection method for early screening of skin tumors based on bioimpedance spectroscopy (BIS) technology. MethodsFirstly, we have established a complete skin stratification model, including stratum corneum, epidermis, dermis, and subcutaneous tissue. And the numerical analysis method was used to investigate the effect of dehydrated and dry skin stratum corneum on contact impedance in BIS measurement. Secondly, differentiation effect of different diameter skin tumor tissues was studied using a skin model after removing the stratum corneum. Then, in order to demonstrate that BIS technology can be used for detecting the microinvasion stage of skin tumors, we conducted a simulation study on the differentiation effect of skin tumors under different infiltration depths. Finally, in order to verify that the designed BIS detection system can distinguish between tumor microinvasion periods, we conducted tumor invasion experiments using hydrogel treated pig skin tissue. ResultsThe simulation results show that a dry and high impedance stratum corneum will bring about huge contact impedance, which will lead to larger measurement errors and affect the accuracy of measurement results. We extracted the core evaluation parameter of relaxed imaginary impedance (Zimag-relax) from the simulation results of the skin tumor model. When the tumor radius (Rtumor) and invasion depth (h)>1.5 mm, the designed BIS detection system can distinguish between tumor tissue and normal tissue. At the same time, in order to evaluate the degree of canceration in skin tissue, the degree of tissue lesion (εworse) is defined by the relaxed imaginary impedance (Zimag-relax) of normal and tumor tissue (εworse is the percentage change in virtual impedance of tumor tissue relative to that of normal tissue), and we fitted a Depth-Zimag-relax curve using relaxation imaginary impedance data at different infiltration depths, which can be applied to quickly determine the infiltration depth of skin tumors after being supplemented with a large amount of clinical data in the future. The experimental results proved that when εworse=0.492 0, BIS could identify microinvasive tumor tissue, and the fitting curve correction coefficient of determination was 0.946 8, with good fitting effect. The simulation using pig skin tissue correlated the results of real human skin simulation with the experimental results of pig skin tissue, proving the reliability of this study, and laying the foundation for further clinical research in the future. ConclusionOur proposed BIS method has the advantages of fast, real-time, and non-invasive detection, as well as high sensitivity to skin tumors, which can be identified during the stage of tumor microinvasion.
ABSTRACT
OBJECTIVE@#To explore the brain effect mechanism and the correlation between brain functional imaging and cognitive function in treatment of depressive disorder (DD) with transcutaneous auricular vagus nerve stimulation (taVNS) based on the resting-state functional magenetic reasonance imaging (rs-fMRI).@*METHODS@#Thirty-two DD patients were included in a depression group and 32 subjects of healthy condition were enrolled in a normal group. In the depression group, the taVNS was applied to bilateral Xin (CO15) and Shen (CO10), at disperse-dense wave, 4 Hz/20 Hz in frequency and current intensity ≤20 mA depending on patient's tolerance, 30 min each time, twice daily. The duration of treatment consisted of 8 weeks. The patients of two groups were undertaken rs-fMRI scanning. The scores of Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA) and Wisconsin card sorting test (WCST) were observed in the normal group at baseline and the depression group before and after treatment separately. The differential brain regions were observed before and after treatment in the two groups and the value of degree centrality (DC) of fMRI was obtained. Their correlation was analyzed in terms of HAMD, HAMA and WCST scores.@*RESULTS@#The scores of HAMD and HAMA in the depression group were all higher than those in the normal group (P<0.05). After treatment, the scores of HAMD and HAMA were lower than those before treatment in the depression group; the scores of total responses, response errors and perseverative errors of WCST were all lower than those before treatment (P<0.05). The brain regions with significant differences included the left inferior temporal gyrus, the left cerebellar peduncles region 1, the left insula, the right putamen, the bilateral supplementary motor area and the right middle frontal gyrus. After treatment, the value of DC in left supplementary motor area was negatively correlated to HAMD and HAMA scores respectively (r=-0.324, P=0.012; r=-0.310, P=0.015); the value of DC in left cerebellar peduncles region 1 was negatively correlated to the total responses of WCST (r=-0.322, P=0.013), and the left insula was positively correlated to the total responses of WCST (r=0.271, P=0.036).@*CONCLUSION@#The taVNS can modulate the intensity of the functional activities of some brain regions so as to relieve depressive symptoms and improve cognitive function.

@#Abstract: Objective The study aims to investigate the diagnosis quality and accuracy of syphilis cases reported by medical facilities in Inner Mongolia, understand possible problems and influencing factors in reporting and diagnosis, providing evidence for the better formulation of syphilis control and prevention. Methods Cross-sectional survey was conducted with 2 counties sampled randomly from 12 municipals of Inner Mongolia, different medical facilities were covered. Syphilis cases reported from July 2019 to June 2020 in medical institutions of different categories were sampled and checked. The quality and accuracy of syphilis case reporting were evaluated according to the identifiers in "Syphilis Diagnosis (WS 273-2018)" and "National STD Case Reporting Quality Management Scheme (2018)". In addition, the basic information of medical institutions and the implementation of syphilis detection in laboratories were investigated, and the physicians who reported the case first were interviewed to understand their mastery of syphilis diagnosis and reporting, thus analyzing the major factors influencing the accuracy of reports. Results The reporting rate of syphilis in medical institutions in Inner Mongolia was 99.04% (311/314), the missing-report rate was 0.96% (3/314), the timely reporting rate was 98.05% (1 659/1 692), the completeness rate was 99.64% (1 686/1 692), the correct rate was 99.35% (1 681/1 692), the accuracy rate of internet-based input was 84.63% (1 432/1 692). There were statistical differences in the quality (χ2=13.95, P<0.05; χ2=11.40, P<0.05) and accuracy (χ2=30.06, P<0.05; χ2=44.93, P<0.05) of reports among different municipals and different types of medical facilities. The accuracy rate of syphilis reporting by medical institutions was 86.17% (1 458/1 692), the correct rate for classifying diagnosis was 87.06% (1 473/1 692), and the accuracy rate of staging was 90.25% (1 527/1 692). Multivariate logistic regression results showed that whether the first-clinic physician attended training in the past three years [OR=6.26, 95%CI: (2.12-18.46)] and whether they grasped the key points of syphilis classification standard [OR=2.79, 95%CI: (1.21-6.46)] influenced report accuracy. Conclusions The quality of reports in Inner Mongolia medical institutions is generally high, but the accuracy rate of reporting and correctness of network input have not yet reached the target requirement of 95%. There is still room for improvement in reporting and diagnostic capabilities. It is suggested to further strengthen the training frequency and coverage for physicians on syphilis diagnosis standard.
ABSTRACT
Objectives: To investigate the current application status and implementation difficulties of extracorporeal cardiopulmonary resuscitation (ECPR) in children with sudden cardiac arrest. Methods: This cross-sectional survey was conducted in 35 hospitals. A Children's ECPR Information Questionnaire on the implementation status of ECPR technology (abbreviated as the questionnaire) was designed, to collect the data of 385 children treated with ECPR in the 35 hospitals. The survey extracted the information about development of ECPR, the maintenance of extracorporeal membrane oxygenation (ECMO) machine, the indication of ECPR, and the difficulties of implementation in China. These ECPR patients were grouped based on their age, the hospital location and level, to compare the survival rates after weaning and discharge. The statistical analysis used Chi-square test and one-way analysis of variance for the comparison between the groups, LSD method for post hoc testing, and Bonferroni method for pairwise comparison. Results: Of the 385 ECPR cases, 224 were males and 161 females. There were 185 (48.1%) survival cases after weaning and 157 (40.8%) after discharge. There were 324 children (84.2%) receiving ECPR for cardiac disease and 27 children (7.0%) for respiratory failure. The primary cause of death in ECPR patients was circulatory failure (82 cases, 35.9%), followed by brain failure (80 cases, 35.0%). The most common place of ECPR was intensive care unit (ICU) (278 cases, 72.2%); ECPR catheters were mostly inserted through incision (327 cases, 84.9%). There were 32 hospitals (91.4%) had established ECMO emergency teams, holding 125 ECMO machines in total. ECMO machines mainly located in ICU (89 pieces, 71.2%), and the majority of hospitals (32 units, 91.4%) did not have pre-charged loops. There were no statistically significant differences in the post-withdrawal and post-discharge survival rates of ECPR patients among different age groups, regions, and hospitals (all P>0.05). The top 5 difficulties in implementing ECPR in non-ICU environments were lack of ECMO machines (16 times), difficulty in placing CPR pipes (15 times), long time intervals between CPR and ECMO transfer (13 times), lack of conventional backup ECMO loops (10 times), and inability of ECMO emergency teams to quickly arrive at the site (5 times). Conclusion: ECPR has been gradually developed in the field of pediatric critical care in China, and needs to be further standardized. ECPR in non-ICU environment remains a challenge.

@#Abstract: Objective To collect extensively drug-resistant tuberculosis (XDR-TB) Mycobacterium tuberculosis strains isolated from Xi'an City between 2019 and 2020, and analyze the drug resistance patterns of XDR-TB strains to second-line anti-tuberculosis drugs and the occurrence of new defined extensively drug-resistant tuberculosis in Xi'an, in order to provide evidence for guiding clinical drug use of multidrug-resistant tuberculosis (MDR-TB) patients. Methods A total of 3 088 strains of Mycobacterium tuberculosis that underwent phenotypic drug susceptibility testing at Xi'an Chest Hospital from January 2019 to December 2020 were retrospectively selected to analyze the resistance of anti-tuberculosis drug. Among the stored MDR-TB strains, 114 strains of preserved multidrug-resistant Mycobacterium tuberculosis were randomly selected for bedaquiline and linezolid susceptibility testing. Combined with the results of previous second-line drug susceptibility testing, the incidence of newly defined extensive drug resistance was analyzed. Results Among the 3 088 Mycobacterium tuberculosis strains analyzed, 411 strains (14.3%) showed resistance to isoniazid, 347 strains (11.2%) showed resistance to rifampicin, 142 strains (4.6%) showed resistance to ethambutol, 550 strains (17.8%) showed resistance to streptomycin, and 237 strains (7.6%) exhibited multidrug resistance. Of 237 MDR-TB strains, the resistance rates of ethambutol, moxifloxacin, rifampicin, sodium para-aminosalicylate, prothioconazole, capreomycin, amikacin, and clofazimine were 44.3%, 26.6%, 33.3%, 24.1%, 5.1%, 4.2%, 3.0%, and 2.5%, respectively. Among the randomly selected 114 MDR-TB strains, none showed resistance to bedaquiline, three showed resistance to linezolid, and one strain met the new definition for extensively drug-resistant tuberculosis. Conclusion In Xi'an City, high rates of resistance among MDR-TB strains are observed for ethambutol, quinolone and sodium para-aminosalicylate, and the drug susceptibility tests should be obtained as much as possible when using these drugs. The incidence of new definition extensively drug-resistant tuberculosis is low, and bedaquiline and linezolid remain effective drugs for the treatment of multidrug-resistant tuberculosis even without drug susceptibility testing results.
ABSTRACT
Long noncoding RNAs (lncRNAs) play a critical role in the regulation of atherosclerosis. Here, we investigated the role of the lncRNA growth arrest-specific 5 (lncR-GAS5) in atherogenesis. We found that the enforced expression of lncR-GAS5 contributed to the development of atherosclerosis, which presented as increased plaque size and reduced collagen content. Moreover, impaired autophagy was observed, as shown by a decreased LC3II/LC3I protein ratio and an elevated P62 level in lncR-GAS5-overexpressing human aortic endothelial cells. By contrast, lncR-GAS5 knockdown promoted autophagy. Moreover, serine/arginine-rich splicing factor 10 (SRSF10) knockdown increased the LC3II/LC3I ratio and decreased the P62 level, thus enhancing the formation of autophagic vacuoles, autolysosomes, and autophagosomes. Mechanistically, lncR-GAS5 regulated the downstream splicing factor SRSF10 to impair autophagy in the endothelium, which was reversed by the knockdown of SRSF10. Further results revealed that overexpression of the lncR-GAS5-targeted gene miR-193-5p promoted autophagy and autophagic vacuole accumulation by repressing its direct target gene, SRSF10. Notably, miR-193-5p overexpression decreased plaque size and increased collagen content. Altogether, these findings demonstrate that lncR-GAS5 partially contributes to atherogenesis and plaque instability by impairing endothelial autophagy. In conclusion, lncR-GAS5 overexpression arrested endothelial autophagy through the miR-193-5p/SRSF10 signaling pathway. Thus, miR-193-5p/SRSF10 may serve as a novel treatment target for atherosclerosis.

ABSTRACT Introduction Knee meniscus injury is a common sports injury, and minimally invasive surgery under knee arthroscopy has become an ideal method to treat meniscus injuries. This surgery rehabilitation has been improved, and several studies on the effects of functional exercise in the range of treatment are still inconclusive. Objective Study the functional exercise rehabilitation effects in patients after sports meniscus injury. Methods Twenty patients with meniscus-medial injury being operated on were selected, including eight men and 12 women. They were randomly divided into neuromuscular and strength training groups (11). Signs and symptoms were assessed before and eight weeks after treatment. JOA score indices and gait tests were compared. The impact of rehabilitation differences was evaluated in each group. Results Eight weeks after rehabilitation in both groups, the scores of the strength training group were higher than the neuromuscular group; the difference between the groups was statistically significant (P<0.05). Conclusion Functional exercise accelerates joint recovery, reflected in increased strength of adjacent muscles. The muscle and joint training effects on postoperative meniscus injury are worthy of recognition. The baropodometry revealed distinctions in walking patterns between different rehabilitation methods. From the perspective of this research, rehabilitation methods combined with proprioceptive exercises are complementary. Evidence Level II; Therapeutic Studies - Investigating the result.

ABSTRACT
ABSTRACT Background: While sarcopenia is an important clinical finding in individuals diagnosed with chronic heart failure (CHF), efforts to identify a reliable biomarker capable of predicting the overall muscular and functional decline in CHF patients have been unsuccessful to date. Objectives: The objectives of this study were to study the diagnostic utility of MicroRNA (miRNA)-1-3p as a predictor of sarcopenia status in individuals diagnosed with CHF. Methods: In total, 80 individuals with heart failure exhibiting a left ventricular ejection fraction < 50% were enrolled in this study. All patients were analyzed to assess miR-1-3p expression levels, with body composition being evaluated through dual-energy X-ray absorptiometry and sarcopenia being defined based on the sum of appendicular lean muscle mass (ALM) divided by height in meters squared and handgrip strength (HGS). In addition, the activation of the Akt/mTOR signaling pathway was evaluated in these individuals. Results: In total, 40 of the enrolled patients (50%) exhibited sarcopenia. Sarcopenic patients presented with increased miR-1-3p expression levels as compared to non-sarcopenic individuals (1.69 ± 0.132 vs. 1.22 ± 0.106; p < 0.05). With respect to sarcopenic indices, appendicular skeletal mass index was most strongly correlated with miR-1-3p expression, which was also strongly correlated with HGS. High levels of Akt/mTOR signaling pathway components were expressed in sarcopenic individuals, highlighting a significant relationship between miR-1-3p activity and signaling through this pathway. Moreover, miR-1-3p was identified as a specific marker for sarcopenia in individuals with CHF. Conclusion: These results suggest that circulating miR-1-3p levels are related to Akt/mTOR pathway activation and can offer valuable insight into the overall physical capacity and muscular integrity of CHF patients as a predictor of sarcopenia.
ABSTRACT
Objective To evaluate the diagnostic efficiency of four anti-cysticercus IgG, IgG4 or IgM antibody test kits (enzyme-linked immunosorbent assay, ELISA) by different manufacturers, so as to provide insights into the epidemiological investigation and clinical detection of cysticercosis. Methods Forty serum samples from cerebral cysticercosis patients, 100 serum samples from healthy volunteers, 30 serum samples from paragonimiasis skrjabini patients, 17 serum samples from cystic echinococcosis and 19 serum samples from subcutaneous or cerebral sparganosis patients were collected and detected using anti-cysticercus IgG, IgG4 or IgM antibody test kits (brand A) and the anti-cysticercus IgG antibody test kit (brand B). The sensitivity, specificity and false negative rate of the four kits for detection of cysticercosis were estimated. Results The anti-cysticercus IgG, IgG4 or IgM antibody test kits (brand A) showed 95.00% (38/40), 87.50% (35/40), 7.50% (3/40) sensitivities and 98.00% (98/100), 100.00% (100/100) and 100.00% (100/100) for detection of cysticercosis, while the anti-cysticercus IgG antibody test kit (brand B) presented a 75.00% (30/40) sensitivity and 100.00% (100/100) specificity for detection of cysticercosis. The sensitivity for detection of cysticercosis was significantly higher by the anti-cysticercus IgG antibody test kit (brand A) than by the anti-cysticercus IgG antibody test kit (brand B) (χ2 = 6.28, P < 0.05); however, no significant difference was seen in the specificity by two kits (χ2 = 2.01, P > 0.05). The four ELISA kits showed overall false positive rates of 37.88% (25/66), 22.73% (15/66), 62.12% (41/66) and 15.15% (10/66) for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 37.61, P < 0.05), and the anti-cysticercus IgG antibody test kit (brand A) presented the highest overall false positive rate for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 7.56, P’ < 0.008), while a higher overall false positive rate was seen for detection of paragonimiasis, echinococcosis and sparganosis by the anti-cysticercus IgG antibody test kit (brand A) than by the anti-cysticercus IgG antibody test kit (brand B) (χ2 = 8.75, P’ < 0.008). The four ELISA kits showed false positive rates of 40.00% (12/30), 16.67% (5/30), 76.67% (23/30) and 13.33% (4/30) for detection of paragonimiasis (χ2 = 32.88, P < 0.05) and 21.05% (4/19), 26.32% (5/19), 73.68% (14/19) and 15.79% (3/19) for detection of sparganosis (χ2 = 19.97, P < 0.05), and the highest false positive rates were found by the anti-cysticercus IgM antibody test kit (brand A) for detection of paragonimiasis and sparganosis (all P’ < 0.008). However, the four ELISA kits showed comparable false positive rates of 52.94% (9/17), 29.41% (5/17), 23.53% (4/17) and 17.65% (3/17) for detection of echinococcosis (χ2 = 8.24, P > 0.05). In addition, the anti-cysticercus IgM anti-body test kit (brand A) showed false positive rates of 76.67% (23/30), 23.53% (4/17) and 73.68% (14/19) for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 14.537, P < 0.05), with the lowest false positive rate seen for detection of echinococcosis (χ2 = 14.537, P’ < 0.014), while no significant differences were seen in the false positive rate for detection of paragonimiasis, echinococcosis and sparganosis by other three ELISA kits (all P > 0.05). Conclusions The four anti-cysticercus IgG, IgG4 or IgM antibody test kits exhibit various efficiencies for serodiagnosis of cysticercosis. The anti-cysticercus IgG antibody test kit (brand A) has a high sensitivity for serodiagnosis of cysticercosis; however, it still needs to solve the problems of cross-reaction with other parasitic diseases and stability.
ABSTRACT
Objective To investigate the changes in the awareness rate of Taenia solium taeniasis and cysticercosis control knowledge among medical professionals before and after training in Fangcheng County, a disease-elimination pilot area of Henan Province, so as to evaluate the effectiveness of the training. Methods Three townships in Fangcheng County were randomly selected as the study townships, including Dushu, Bowang and Yangji townships, while Erlangmiao, Yanglou and Xiaoshidian townships in the county were randomly selected as the control townships. The grassroots medical professionals in the study townships were given once training on T. solium taeniasis and cysticercosis control knowledge each year from 2016 to 2020, while those in the control townships were given no interventions. All village-level doctors and a part of township-level public health professionals were sampled from the study and control townships as intervention and control groups. The baseline and final assessments of the awareness of T. solium taeniasis and cysticercosis control knowledge were performed using questionnaire survey in intervention and control groups in 2016 and 2020, and the awareness of T. solium taeniasis and cysticercosis control knowledge was compared between the two groups. Results A total of 663 medical professionals were investigated in Fangcheng County from 2016 to 2020, including 474 participants in the intervention group and 189 participants in the control group. Results from the 2016 baseline survey showed that the awareness rate of T. solium taeniasis and cysticercosis control knowledge was 28.83% (47/163) among grassroots medical professionals in Fangcheng County, and there were no significant differences in the awareness between the intervention (32.47%, 25/77) and control groups (25.58%, 22/86) (χ2 = 0.939, P > 0.05), between men (30.50%, 43/141) and women (18.18%, 4/22) (χ2 = 1.406, P > 0.05) or between village- (31.39%, 43/137) and township-level medical professionals (15.38%, 4/26) (χ2 = 2.727, P > 0.05), while significant differences were found in the awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in terms of education levels (χ2 = 8.190, P < 0.05) and duration of working experiences (χ2 = 12.617, P < 0.05), and the awareness rate of T. solium taeniasis and cysticercosis control knowledge increased with education levels among medical professionals (χ2 = 6.768, P < 0.05). Only 5.52% (9/163) of the medical professionals had a history of diagnosis and therapy of T. solium taeniasis or cysticercosis, and only 1.23% (2/163) received training on T. solium taeniasis and cysticercosis control knowledge during the past 5 years. Results from the 2020 questionnaire survey showed a higher awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in the intervention group (93.55%, 116/124) than in the control group (46.60%, 48/103) (χ2 = 61.845, P < 0.05), and no significant differences were seen in the awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in terms of gender, level of medical professionals, duration of working experiences or history of diagnosis/therapy of T. solium taeniasis and cysticercosis in the intervention group (χ2 = 1.089, 0.140, 0.081 and 0.453, all P values > 0.05), while there was a significant difference in the awareness rate among medical professionals with different education levels (χ2 = 36.338, P < 0.05). In addition, the awareness rate of T. solium taeniasis and cysticercosis control knowledge significantly increased among medical professionals with various chracteristics in 2020 than in 2016. Conclusions In the low-prevalence areas of T. solium taeniasis and cysticercosis, long-term and persistent training may improve the awareness of T. solium taeniasis and cysticercosis control knowledge among grassroots medical professionals, which facilitates the timely identification of T. solium taeniasis and cysticercosis and the establishment of a sensitive disease surveillance system.
ABSTRACT
Objective:To compare the clinical effective of clavicular hook plate with extra suture hole and traditional hook plate in the treatment of acute acromioclavicular dislocation.Methods:This study retrospectively analyzed the clinical data of traumatic acromioclavicular dislocation patients who were treated by operation from March 2017 to September 2020. The patients were included in traditional hook plate (THP) group and triangle stabilization technique hook plate (TSTHP) group according fracture fixations. TSTHP group adopted clavicular hook plate with extra suture hole. There were 27 patients in THP group with 18 male patients and 9 female patients; average age with 37.56±8.94 years old; 16 patients injured left side and 11 patients injured right side; crush injuries of 10 patients, traffic injuries of 9 patients and sports injuries of 8 patients; Rockwood classification of type III (9 patients), type IV (10 patients) and type V (8 patients). There were 20 patients in TSTHP group with 15 male patients and 5 female patients; average age with 38.95±9.91 years old; 13 patients injured left side and 7 patients injured right side; crush injuries of 9 patients, traffic injuries of 8 patients and sports injuries of 3 patients; Rockwood classification of type III (5 patients), type IV (9 patients) and type V (6 patients). The operation time, intraoperative bleeding, postoperative coracoclavicular space, visual analogue scale (VAS) and shoulder joint Constant-Murley score were compared between the two groups.Results:The operation time and blood loss of THP group and TSTHP group were 51.07±11.27 min, 87.41±15.34 ml and 55.65±8.59 min, 90.50±14.32 ml, respectively. The difference was not statistically significant ( t=1.52, 0.70, all P>0.05). Patients in both groups were followed up for 12 to 14 months after operations, with an average of 12.28 months. Six months after surgery, the coracoclavicular spaces of THP group and TSTHP group were 12.16±0.90 mm and 11.26±0.70 mm, respectively. The difference was statistically significant ( t=3.70, P<0.001). Postoperative VAS scores (2 days, 3 months, 6 months and 12 months) of TSTHP group [1.8±0.77, 0.00(0.00, 1.00), 0.00 (0.00, 0.00), 0.00(0.00, 0.00)] were significantly better than THP group [4.22±1.25, 2.00 (1.00, 3.00), 1.00 (0.00, 1.00), 0.00 (0.00, 1.00)]. The difference was statistically significant ( t=7.65, P<0.001; Z=4.85, P<0.001; Z=3.44, P=0.001; Z=2.96, P=0.003). Postoperative Constant-Murley scores (3 months, 6 months and 12 months) of TSTHP group (87.00±5.18, 91.25±2.75, 92.30±2.74) were significantly better than THP group (76.96±5.21, 83.22±3.86, 85.22±3.49). The difference was statistically significant ( t=6.54, 7.93, 7.51; P<0.001). The postoperative complication rates of THP group were higher than TSTHP group [70.4% (19/27) vs. 5.0% (1/20)]. Conclusion:In the treatment of acute acromioclavicular dislocation, the clavicular hook plate with extra suture hole can obtain satisfactory clinical effect compared with the THP, and clavicular hook plate with extra suture hole is more conducive to early recovery of shoulder function and reduce postoperative complications.
ABSTRACT
Objective@#To explore the association between drinking behavior and self injury behavior in adolescents.@*Methods@#A total of 9 247 students from 4 middle schools were investigated. Drinking behavior and self injury behavior were collected from questionnaire survey. Univariate and multivariate Logistic regression analysis were used to analyze the relationship between drinking behavior and self injury behavior.@*Results@#Among the 9 247 middle school students, 52.8% reported ever drinking, 24.9% reported drinking behavior in the past 30 days, and 14.6% reported been drunk in the past year. The average age of drinking for the first time was 12.47±3.05. About 47.2% of the participants had self injury behavior. Male with younger drinking age ( OR =1.52), had been drunken ( OR =1.35) and frequent drinking ( OR =1.54) increased the incidence of self injury. Female reported drinking at younger age ( OR =1.69), had been drunk ( OR =1.82) and lived in cities and towns ( OR =1.20) had a higher risk of self injury.@*Conclusion@#Drinking at younger age, heavy and frequent drinking are associated with higher risk of self injury in adolescents in sex specific fashion.
ABSTRACT
Objective To compare the changes of knowledge, attitude and practice (KAP) related to taeniasis and cysticercosis among primary school students before and after health education interventions in disease-elimination pilot areas of Henan Province, so as to evaluate the effectiveness of health education interventions. Methods A primary school was selected from each of Dushu, Bowang and Yangji townships, Fangcheng County, Henan Province from 2017 to 2019; then, 2 to 3 classes were randomly selected from grade 4 to 6 in each primary school, and finally, all students in these classes were enrolled as study subjects. A thematic health education lecture pertaining to taeniasis and cysticercosis was given once each year by means of “health education in class”. The KAP towards taeniasis and cysticercosis was investigated among primary school students using selffilled structured questionnaires, and the changes of awareness of taeniasis and cysticercosis control knowledge and percentage of healthy behaviors formation were compared in primary school students among years and following various frequencies of health education interventions. Results More than 10 thousand person-time primary school students received health education interventions during the period from 2017 to 2019, and a total of 1 223 person-time primary school students were investigated during the 3-year study period, including 633 person-time men and 590 person-time women and 88.55% of primary school students at ages of 10 to 12 years. The proportion of households raising pigs and using dry toiliets decreased from 5.30% (24/453) and 18.10% (82/453) in 2017 to 3.60% (13/361) and 11.08% (40/361) in 2019, respectively. The awareness rate of taeniasis and cysticercosis control knowledge increased significantly from 0.22% (1/453) in 2017 to 62.59% (256/409) in 2018 and 76.73% (277/361) in 2019 (χ2 = 567.60, P < 0.001), and the awareness rate was 85.25% (104/122) among primary school students attending the thematic special health education courses for successive three times. The awareness rates of taeniasis and cysticercosis control knowledge were 0.44% (1/225), 58.00% (116/200) and 71.63% (149/208) among male students and 0 (0/338), 66.99% (140/209) and 83.66% (128/153) among female students from 2017 to 2019, and there was a significant difference in the awareness of taeniasis and cysticercosis control knowledge between male and female students in 2019 (χ2 = 7.14, P = 0.01). On-site teaching by doctors was the students’ favorite way to receive health education interventions (70.07%, 857/1 223), followed by watching health education videos (58.63%, 717/1 223) and seeing parasite specimens (48.9%, 598/1 223). The proportion of students’ families who used cutting boards for raw and cooked food separately increased from 7.28% (33/453) in 2017 to 47.37% (171/361) in 2019, was 67.21% (82/122) among students attending the health education courses for successive three times. The proportion of students who frequently washed their hands before meals and after using toilet increased from 71.96% (324/453) in 2017 to 89.47% (319/361) in 2019 and was 95.90% (117/122) among students attending the health education courses for successive three times. In addition, the percentage of students washing hands frequently in families using dry toilets was significantly lower in those who did not use dry toilets (χ2 = 9.21, P = 0.002), and the proportion of students with a habit of eating raw or undercooked meat decreased significantly from 35.76% (162/453) in 2017 to 6.65% (24/361) in 2019 (χ2 = 69.11, P < 0.01). Conclusion The thematic health education activity of “health education in class” contributes greatly to the increase in the awareness of taeniasis and cysticercosis control knowledge and the rate of healthy behaviors formation among primary school students in diseaseelimination pilot areas of Henan Province.
ABSTRACT
Objective@#For the proper treatment of first-episode psychosis, assessment of treatment response, remission, relapse, and recovery is important. Therefore, the present study aimed to develop operational definitions of clinical outcomes in first-episode psychosis. @*Methods@#A questionnaire was developed by a panel of experts and underwent three revisions. The final survey was presented to 150 psychiatrists who were members of the Korean Society for Schizophrenia Research. Respondents selected factors that they believed were important to consider while defining treatment response, remission, relapse, and recovery using a 6-point Likert scale. Selected factors that constituted each definition were statistically extracted, and operational definitions were developed. @*Results@#A total of 91 experts responded to the survey. The extent of reduction in psychopathology, socio-occupational functioning, and duration of each state were the core factors of each definition. Outcomes obtained from discussions and consultations by experts have been summarized and proposed. @*Conclusion@#The criteria developed in this survey tended to be somewhat stricter than those used by other studies. The fundamental reason for this is that this survey focused on first-episode psychosis. A better understanding of each definition in first-episode psychosis is necessary to improve effective treatment outcomes.
ABSTRACT
Objective:The phase separation of Baihutang was carried out. The content of mangiferin,new mangiferin,calciumion,glycyrrhizin and ammonium glycyrrhizinate in the solution phase,the nano phase and the precipitated phase of Baihutang were measured,so as to define the effect of nanometer particles of Baihutang on the growth of active components,and explain the mechanisms of Baihutang in potent detoxification and heat removal. Method:The phase separation of Baihutang was performed by high-speed centrifugation and dialysis. The contents of mangiferin,new mangiferin,glycyrrhizin and ammonium glycyrrhizinate in Baihutang were determined by HPLC. Chromatographic column Diamonsil C18 (4.6 mm×250 mm,5 μm) was adopted, with acetonitrile-25 mmol·L-1 potassium dihydrogen phosphate solution as the mobile phase, and eluted in a gradient mode. The detection wavelength was 257 nm,the column temperature was 30 ℃,and the flow rate was 1.0 mL·min-1. EDTA-2Na solution was used to calibrate the calcium concentration in different phase states of Baihutang. Result:1 mL Baihutang nanoparticles contained 483.00 μg new mangiferin,1 068.88 μg mangiferin,219.93 μg glycyrrhizin and 187.10 μg ammonium glycyrrhizin,and the content of new mangiferin and mangiferin accounted for 89.4% and 89.9% respectively in 1 mL Baihutang. The new mangiferin and mangiferin in the nano phase were 230.0 and 23.3 times the true solution,and 8.5 and 14.4 times of the precipitation,respectively. The content of calcium ions in Baihutang in the nano phase was higher,accounting for 86.9% of Baihutang,and the content of calcium ions in Baihutang and Baihutang in the nano phase was higher than that in gypsum group. Conclusion:The content of main components in Baihutang in nanometer phase is significantly higher than that in other phases. The nanoparticles of Baihutang have a solubilizing effect on the main antipyretic components, such as mangiferin,mangiferin and calcium ions as well as the antitoxic components glycyrrhizic acid and glycyrrhizic acid. The mechanism of action of Baihutang is related to the formation of nanoparticles.
ABSTRACT
Abstract Background Osteoporosis (OP) is common in patients with chronic obstructive pulmonary disease (COPD). The relationship between OP and COPD has been primarily studied in male patients, and few reports are available in postmenopausal women. Objective The purpose of this study was to investigate the association between bone mineral density (BMD) and COPD in postmenopausal women. Methods This cross-sectional study included 133 clinically stable female ex-smokers with confirmed COPD, and 31 age-matched ex-smoker female controls. We analyzed groups according to their airway obstruction category. BMD was measured on dual-energy X-ray absorptiometry images of the left femoral neck. Results Patients with COPD had lower T-scores and higher prevalence of osteopenia/OP than the control group. In the COPD group, the airway obstruction category was significantly associated with the T-score after adjustment for confounders. Multivariate logistic regression analysis showed COPD was an independent marker for increased risk of osteopenia/OP in postmenopausal women. Conclusions COPD and airway obstruction category were strongly related to BMD. Postmenopausal women with COPD, especially those with severe airway obstruction, had a higher prevalence rate and a higher risk of osteopenia and OP than female controls without COPD.

Objective@#To understand the awareness level of AIDS knowledge and its influencing factors among middle school students from AIDS high prevalence areas of Yi Autonomous Prefecture (Liangshan Prefecture), and to provide a reference for making propaganda strategies of AIDS knowledge and intervention measures in the relevant departments.@*Methods@#Totally 10 749 students in 4 middle schools were selected from AIDS high prevalence areas of Yi Autonomous Prefecture in Liangshan by the method of cluster sampling. A self-made questionnaire was used to investigate the ways of getting AIDS knowledge and the condition of conducting AIDS life training skills in school.@*Results@#The awareness rate of AIDS-related knowledge among middle school students in Liangshan Prefecture was 44.4%. According to the results of multivariate Logistic regression analysis, female students, junior grade, Yi nationality, poor self-evaluation, lack of parents, living in rural areas, good family economic condition (student self-assessment), living in a community of Yi nationality were all the dangerous factors to the awareness rate of AIDS. School education, radio and television, and health promotion were the main ways for students to acquire AIDS knowledge(88.82%, 80.83%, 73.54%). Minority students, students in severely affected areas received less AIDS life skills training in schools, the time was later, and student needs were not strong.@*Conclusion@#The AIDS awareness level of middle school students in Liangshan AIDS high-incidence area is too low, so it is necessary to pay attention to develop targeted programs to strengthen AIDS health education for middle school students.
