Objective:To investigate the clinical characteristics of 130 children with severe SARS-CoV-2 infection in Yunnan province after the relaxation of non-pharmaceutical interventions, and analyze the risk factors for mortality.Methods:This study is a retrospective case summary that analyzed the demographic data, underlying diseases, clinical diagnoses, disease outcomes, and laboratory results of 130 children with severe COVID-19 infections admitted to nine top-tier hospitals in Yunnan Province from December 2022 to March 2023. According to the prognosis, the patients were divided into survival group and death group. The clinical and laboratory data between the two groups were compared, and the risk factors of death were evaluated. The χ2 test and Mann-Whitney U test were employed to compare between groups, while Spearman correlation test and multiple Logistic regression were used to analyze the risk factors for death. The predictive value of independent risk factors was evaluated by receiver operating characteristic curve. Results:The 130 severe patients included 80 males and 50 females with an onset age of 28.0 (4.5, 79.5) months. There were 97 cases in the survival group and 33 cases in the death group with no significant differences in gender and age between the two groups ( P>0.05). Twenty-five cases (19.2%) out of the 130 patients had underlying diseases, and the number with underlying diseases was significantly higher in death group than in survival group (36.4% (12/33) vs. 13.4%(13/97), χ2=8.36, P=0.004). The vaccination rate in the survival group was significantly higher than that in the death group (86.1% (31/36) vs. 7/17, χ2=9.38, P=0.002). A total of 42 cases (32.3%) of the 130 patients were detected to be infected with other pathogens, but there was no significant difference in the incidence of co-infection between the death group and the survival group (39.3%(13/33) vs. 29.9% (29/97), χ2=1.02, P>0.05). Among the 130 cases, severe respiratory cases were the most common 66 cases (50.8%), followed by neurological severe illnesses 34 cases (26.2%) and circulatory severe 13 cases (10%). Compared to the survival group, patients in the death group had a significantly higher levels of neutrophil, ferritin, procalcitonin, alanine aminotransferase, lactate dehydrogenase, creatine kinase isoenzyme, B-type natriuretic peptide, interleukin-6 and 10 (6.7 (4.0, 14.0) vs. 3.0 (1.6, 7.0)×10 9/L, 479 (298, 594) vs. 268 (124, 424) μg/L, 4.8 (1.7, 10.6) vs. 2.0 (1.1, 3.1) μg/L, 66 (20, 258) vs. 23 (15, 49) U/L, 464 (311, 815) vs. 304 (252, 388) g/L, 71(52, 110) vs. 24(15, 48) U/L, 484 (160, 804) vs. 154 (26, 440) ng/L, 43 (23, 102) vs. 19 (13, 27) ng/L, 216 (114, 318) vs. 86 (45, 128) ng/L, Z=-4.21, -3.67, -3.76, -3.31, -3.75, -5.74, -3.55, -4.65, -5.86, all P<0.05). The correlated indexes were performed by multivariate Logistic regression and the results showed that vaccination was a protective factor from death in severe cases ( OR=0.01, 95% CI 0-0.97, P=0.049) while pediatric sequential organ failure assessment (PSOFA) ( OR=3.31, 95% CI 1.47-7.47, P=0.004), neutrophil-to-lymphocyte ratio (NLR) ( OR=1.56, 95% CI 1.05-2.32, P=0.029) and D dimer ( OR=1.49, 95% CI 1.00-1.02, P=0.033) were independent risk factors for death (all P<0.05). The area under the curve of the three independent risk factors for predicting death were 0.86 (95% CI 0.79-0.94), 0.89 (95% CI 0.84-0.95) and 0.87 (95% CI 0.80-0.94), all P<0.001, and the cut-off values were 4.50, 3.66 and 4.69 mg/L, respectively. Conclusions:Severe SARS-CoV-2 infection can occur in children of all ages, primarily affecting the respiratory system, but can also infect the nervous system, circulatory system or other systems. Children who died had more severe inflammation, tissue damage and coagulation disorders. The elevations of PSOFA, NLR and D dimer were independent risk factors for death in severe children.

Objective:To explore the effects of early debridement and conservative eschar removal followed by wound coverage with acellular dermal matrix (ADM), i.e., early surgery, in the treatment of children with deep burns.Methods:This study was a retrospective cohort study. From January 2017 to December 2022, 278 deep burned hospitalized children aged 1-7 years who met the inclusion criteria were admitted to Central Hospital Affiliated to Shandong First Medical University. According to the differences in treatment processes, 134 children who underwent early surgery+routine dressing change were enrolled in eschar removal+dressing change group (77 males and 57 females, aged 1 (1, 2) years), and 144 children who underwent only routine dressing change were enrolled in dressing change alone group (90 males and 54 females, aged 1 (1, 2) years). Fifty-one children without full-thickness burns in eschar removal+dressing change group were enrolled in eschar removal+dressing change group 1 (26 males and 25 females, aged 1 (1, 2) years), and 57 cases of the 83 children with full-thickness burns who did not undergo autologous skin grafting at the same time of early surgery (namely early skin grafting) in eschar removal+dressing change group were included in eschar removal+dressing change group 2 (37 males and 20 females, aged 1 (1, 2) years). Seventy-six children without full-thickness burns in dressing change alone group were included in dressing change alone group 1 (51 males and 25 females, aged 1 (1, 3) years), and 68 children with full-thickness burns in dressing change alone group were included in dressing change alone group 2 (39 males and 29 females, aged 1 (1, 2) years). For deep partial-thickness burn wounds and small full-thickness burn wounds in eschar removal+dressing change group, the eschar removal was performed on the basis of retaining a thin layer of denatured dermis so as to preserve the healthy tissue of the wound base, and ADM was applied to all wounds externally after eschar removal. For larger full-thickness burn wounds in this group, especially those located in the functional part of joints, eschar removal to the plane layer of viable tissue and early autologous skin grafting was needed. When the superficial wounds of children healed or tended to heal, the residual wounds were evaluated, and elective autologous skin grafting was performed if it was difficult to heal within 14 days. The healing time, intervention healing time, times of operation/dressing change, and times of intervention operation/dressing change in children with deep partial-thickness burn wounds of children in eschar removal+dressing change group, dressing change alone group, eschar removal+dressing change group 1, and dressing change alone group 1 were recorded. At the last follow-up (follow-up period was set to 7-12 months), the modified Vancouver scar scale (mVSS) scores of the most severe area of scar hyperplasia of healed deep partial-thickness burn wounds of 54 children in eschar removal+dressing change group and 48 children in dressing change alone group were recorded. The healing time and times of operation/dressing change of all burn wounds of children in eschar removal+dressing change group and dressing change alone group, and the healing time and times of operation/dressing change of full-thickness burn wounds of children in eschar removal+dressing change group 2 and dressing change alone group 2 were recorded. The incidences of wound infection, sepsis, fever, and fever after 5 days of burns in children of eschar removal+dressing change group and dressing change alone group during wound healing.Results:Compared with those in dressing change alone group, the healing time and intervention healing time were significantly shortened, and the times of operation/dressing change and times of intervention operation/dressing change were significantly reduced in children with deep partial-thickness burn wounds in eschar removal+dressing change group (with Z values of -11.00, -11.33, -12.64, and -11.65, respectively, P<0.05). Compared with those in dressing change alone group 1, the healing time and intervention healing time were significantly shortened, and the times of operation/dressing change and times of intervention operation/dressing change were significantly reduced in children with deep partial-thickness burn wounds in eschar removal+dressing change group 1 (with Z values of 6.57, 6.46, 8.04, and 6.57, respectively, P<0.05). At the last follow-up, the mVSS score of the most severe scar hyperplasia area of healed deep partial-thickness burn wounds of 54 children in eschar removal+dressing change group was 4.00 (3.00,5.00), which was significantly lower than 6.50 (5.00,7.00) of 48 children in dressing change alone group ( Z =-4.67, P<0.05).Compared with those in dressing change alone group, the healing time was significantly shortened, and times of operation/dressing change was significantly reduced in all burn wounds in eschar removal+dressing change group (with Z values of -5.20 and -6.34, respectively, P<0.05). Compared with those in dressing change alone group 2, the healing time was significantly shortened, and times of operation/dressing change was significantly reduced in full-thickness burn wounds in eschar removal+dressing change group 2 (with Z values of -5.22 and -5.73, respectively, P<0.05). During wound healing, the probabilities of fever and fever after 5 days of burns in children of eschar removal+dressing change group were significantly lower than those in dressing change alone group (with χ2 values of 4.13 and 3.91, respectively, P<0.05); only 1 child in dressing change alone group developed sepsis, and there was no statistically significant difference in the wound infection rate of children in the two groups ( P>0.05). Conclusions:For children with deep burns, early surgery, and early skin grafting or elective autologous skin grafting as needed, have better short-term and long-term effects than those without early surgery.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective:To analyze the current mental health status of employees in large public hospitals and its correlation with factors such as social support.Methods:A cross-sectional study was conducted in November 2023. Using cluster sampling, employees from Beijing Hospital, China-Japan Friendship Hospital, and the Cancer Hospital of the Chinese Academy of Medical Sciences were surveyed. An electronic questionnaire was used to collect indicators related to mental health. Mental health status was assessed using a self-evaluation questionnaire, with scores ≤6 indicating good mental health and scores ≥7 indicating the need for attention. A total of 3 828 questionnaires were distributed, and 3 803 valid responses were included in the final analysis. The study analyzed the current mental health status and its correlation with factors such as social support among the included employees. Social support indicators included living alone, frequency of contact with relatives or friends, and participation in group activities. Other factors included job type (physicians, nurses, medical technicians and researchers, and administrative and logistical employees), gender, professional title, education level, and satisfaction with workplace benefits.Results:The study included 3 803 respondents, comprising 874(23.0%) males and 2 929 (77.0%) females; 743 (19.5%) aged ≤30 years, 2 177 (57.2%) aged 31-45 years, and 883 (23.2%) aged >45 years. Among them, 1 238 (32.6%) employees needed attention for their mental health. The female, nurse, unmarried, post-graduate degree or less, and employees with low satisfaction with unit welfare need to pay attention to their mental health (all P<0.05), their total social support score ( t=138.59, P<0.001) and grade ( χ2=255.25, P<0.001) are lower. In terms of social support factors, non-living alone, frequent communication with relatives and friends and participation in group activities were independent protective factors for mental health (all P<0.05). The protective association between education and mental health of female workers was stronger than that of male workers (female OR=0.348, 95% CI: 0.198-0.614 vs male OR=0.653, 95% CI: 0.430-0.994). Non-living alone was the only protective factor for nurses′ mental health ( OR=0.515, 95% CI: 0.367-0.723); However, high professional title ( OR=0.362, 95% CI: 0.182-0.720) and educational background ( OR=0.365, 95% CI: 0.175-0.758) were only protective factors for physicians′ mental health (all P<0.05). Conclusions:The mental health of employees in large public hospitals is differentiated among different subgroups, such as gender, position and educational background, which needs attention in general. In terms of social support factors, non-living alone, frequent communication with relatives and friends, and participation in group activities were associated with good mental health. Hospital trade unions and other departments should carry out more targeted help and support to create a better mental health environment for employees.

Objective:To investigate the status of iodine deficiency disorders in children and pregnant women in Ganzhou City, Jiangxi Province, and to provide a basis for scientific iodine supplementation and adjustment of prevention and control strategies.Methods:According to the requirements of the National Iodine Deficiency Disorders Surveillance Program (2016 Edition), iodine deficiency disorders surveillance was carried out in 18 counties (cities, districts) under the jurisdiction of Ganzhou City from 2018 to 2022. Edible salt and urine samples taken from children aged 8 to 10 and pregnant women were collected to detect salt and urine iodine levels. At the same time, B-ultrasound method was adopted to measure children's thyroid volume, and the goiter rate was calculated.Results:From 2018 to 2022, a total of 27 075 edible salt samples were collected from key populations (children aged 8 - 10 and pregnant women), with a median salt iodine of 25.00 mg/kg and a qualified iodized salt consumption rate of 96.24% (26 057/27 075). The difference in the qualified iodized salt consumption rate among key populations in different years was statistically significant (χ 2 = 29.09, P < 0.001). A total of 18 061 urine samples were collected from children, with a median urine iodine of 192.10 μg/L, there was a statistically significant difference in the urine iodine level of children between different years ( H = 82.59, P < 0.001). A total of 9 014 urine samples were collected from pregnant women, with a median urine iodine of 177.20 μg/L, there was a statistically significant difference in urine iodine level of pregnant women between different years ( H = 78.78, P < 0.001). A total of 8 621 children's thyroid glands were examined, including 34 cases of goiter, with a goiter rate of 0.39%, and the goiter rate showed a decreasing trend year by year (χ 2trend = 11.09, P < 0.001). Conclusions:From 2018 to 2022, the iodine nutrition of children and pregnant women in Ganzhou City is at an appropriate level, the consumption rate of qualified iodized salt (> 90%) and the children's goiter rate (< 5%) met the national iodine deficiency disorders elimination standards. Ganzhou City continues to maintain the status of eliminating iodine deficiency disorders.

Objective:To investigate the clinical diagnostic value of MRI retention enema cannula enhanced scanning in the high complex anal fistula.Methods:The clinical data of 60 anal fistula patients underwent surgery treatment from May 2020 to May 2022 in Affiliated Hospital of Shanxi University of Traditional Chinese Medicine were retrospectively analyzed. All patients underwent MRI plain scanning and enhanced scanning before operation. Compared with the surgical results, the difference between MRI plain scanning and enhanced scanning in the diagnosis of high complex anal fistula was compared.Results:All of the 60 patients successfully completed surgical treatment, and 58 cases internal orifices, 55 cases complex anal fistulas and 53 cases high anal fistulas were found intraoperatively. MRI plain scanning results showed 32 cases internal orifices, 46 cases complex anal fistulas and 42 cases high anal fistulas were found. MRI enhanced scanning results showed 54 cases internal orifices, 53 cases complex anal fistulas and 50 cases high anal fistulas were found. Based on surgical results, the coincidence rates of internal orifice, complex anal fistula and high anal fistula in MRI enhanced scanning were significantly higher than those in MRI plain scanning: 93.10% (54/58) vs. 55.17% (32/58), 96.36% (53/55) vs. 83.64% (46/55) and 94.34% (50/53) vs. 79.25% (42/53), and there were statistical differences ( χ2 = 21.76, 4.95 and 5.27; P<0.01 or <0.05). Conclusions:The MRI retention enema cannula enhanced scanning has obvious advantages in the diagnosis of high complex anal fistula, which provides scientific reference value for the diagnosis and operation of high complex anal fistula in clinic.

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.

Abstract: Cell death is a fundamental biological phenomenon that is essential for the survival and development of organisms. Cell death can be either a spontaneous programmed process by the host or an accidentally triggered process. According to the different signaling pathway activated by various stimulates, programmed cell death exhibits the lytic or non-lytic morphology. For example, apoptosis, a typical non-lytic form of cell death, exhibits cell shrinkage and induces the formation of apoptotic bodies. Pyroptosis mediated by cysteine-containing aspartate-specific protease-1/11 (caspase-1/11) and necroptosis can induce inflammatory reactions and promote cell lysis to release inflammatory cytokines via triggering the pore-forming mechanism of the cell membrane, representing a typical modes of lytic cell death. In addition, the release of reactive oxygen species caused by the damaged mitochondria may further trigger ferroptosis during the pathogen infection. Programmed cell death can play an immune defensive role by eliminating infected cells and intracellular pathogens and stimulating the innate immune response through the resulting cell corpses. Here, we discuss the molecular mechanisms of five programmed cell death pathways: apoptosis, pyroptosis, ferroptosis, necroptosis and PANoptosis. We describe their roles in the innate immune defense against bacterial infections and give a brief statement of the interactions between the different programmed cell death, hoping to provide new insights for in-depth study of the pathogenic mechanisms of infectious diseases.
