Association between subthreshold depression and psychotic like experiences with non suicidal self injury among adolescents in Shandong Province / 中国学校卫生

Objective@#To investigate the association between subthreshold depression, psychotic like experiences (PLEs), and their interactions with non suicidal self injury (NSSI) in adolescents from Shandong, so as to provide a reference for the prevention and early intervention of NSSI in adolescents.@*Methods@#A random cluster sampling method was used to select a total of 6 090 adolescents aged 13-22 from two cities along the coast and inland of Shandong Province. Electronic surveys were administered using the SelfInjurious Behavior Questionnaire, Community Assessment of Psychic Experiencepositive 8 items(CAPE-P8), and the Center for Epidemiological Studies Depression Scale(CES-D). The relationship between subthreshold depression, PLEs, and their interaction with NSSI was analyzed using multivariate Logistic regression.@*Results@#The detection rate of NSSI among adolescents was 21.3%. The highest NSSI reporting rate (27.9%) was found in the age group of 13-15 years.The NSSI reporting rates for those detected with subthreshold depression and PLEs were 49.9% and 30.7%, respectively. Multivariate analysis indicated that individuals with subthreshold depression were 3.47 times more likely to engage in NSSI [OR(95%CI)=3.47(2.68-4.50)]. Those identified with PLEs had 5.32 times higher risk of engaging in NSSI than those without such experiences [OR(95%CI)=5.32(4.10-6.89)]. When both subthreshold depression and PLEs coexist, the risk of engaging in NSSI was 18.47 times higher than in individuals with neither condition [OR(95%CI)=18.47(14.75-23.13)] (P<0.01). The relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (S) were 11.44, 0.61, and 2.89, respectively, indicating that the combined interaction of subthreshold depression and PLEs accounted for 61% of adolescent NSSI.@*Conclusions@#Subthreshold depression and psychoticlike experiences are associated NSSI in adolescents and exhibit an additive interaction. Alleviating subthreshold depression in adolescents and reducing psychotic experiences may play a positive role in preventing the occurrence of NSSI.

Clinical application status of multiple localization methods in the treatment of pulmonary nodules by sub-lobectomy / 中国胸心血管外科临床杂志

@#The precise localization of pulmonary nodules has become an important technical key point in the treatment of pulmonary nodules by thoracoscopic surgery, which is a guarantee for safe margin and avoiding removal of too much normal lung parenchyma. With the development of medical technology and equipment, the methods of locating pulmonary nodules are also becoming less trauma and convenience. There are currently a number of methods applied to the preoperative or intraoperative localization of pulmonary nodules, including preoperative percutaneous puncture localization, preoperative transbronchial localization, intraoperative palpation localization, intraoperative ultrasound localization, and localization according to anatomy. The most appropriate localization method should be selected according to the location of the nodule, available equipment, and surgeon鈥檚 experience. According to the published literatures, we have sorted out a variety of different theories and methods of localization of pulmonary nodules in this article, summarizing their advantages and disadvantages for references.

Primary drug resistance among HIV-1 patients in Hubei Province in 2020-2022 / 公共卫生与预防医学

Objective To investigate the prevalence of primary drug resistance among HIV-1 patients in Hubei Province from 2020 to 2022, and to provide corresponding basis and data support for HIV antiviral therapy (ART) in Hubei Province. Methods During 2020-2022, plasma samples of HIV-1 infected patients before ART were collected., Patients’ demographic data and baseline laboratory test data were also collected. HIV-1 pol region was amplified by in-house method for sub-type typing and drug-resistant mutation site analysis. Results The pol gene sequence was successfully amplified in 242 of 285 cases, with a success rate of 84.9%. CRF07_BC was the predominant HIV-1 sub-type, accounting for 47.11% (114/242), followed by CRF01_AE, accounting for 25.21% (61/242), sub-type B, accounting for 14.16% (35/242), and CRF55_01B, accounting for 4.13% (10/242). The primary resistance rate was 6.20% (15/242). The mutation site of nucleoside reverse transcriptase inhibitors (NRTIs) was mainly M184V, and the mutation sites of non-nucleoside reverse transcriptase inhibitors (NNRTIs) were mainly E138A/G/EG and V179E. These different mutation sites led to different degrees of drug resistance to 12 drugs. The incidence of drug resistance mutation of CRF55_01B sub-type was significantly higher than that of other sub-types. Conclusion The primary drug resistance rate of HIV-1 infected patients is at a slightly high level in Hubei Province, and close monitoring of primary drug resistance and mutation sites should be strengthened before ART, especially for CRF55_01B sub-type.

Efecto del implante anticonceptivo sub-dérmico de Etonogestrel sobre el peso corporal en mujeres en edad reproductiva

Objetivo: Analizar el efecto sobre el peso corporal de la anticoncepción hormonal continua mediante implante sub-dérmico liberador de etonogestrel (ENG) en mujeres en edad reproductiva atendidas en la consulta de planificación familiar de un hospital venezolano. Métodos: Investigación comparativa, con diseño cuasi experimental, de casos y controles, a etiqueta abierta, y prospectivo; con una muestra intencionada de 60 mujeres separadas para recibir bien sea un implante subdérmico (Implanon NXT®; casos) o un dispositivo intrauterino (DIU) de cobre (T de cobre; controles). Se evaluaron el peso corporal e índice de masa corporal antes y posterior de doce meses del uso del contraceptivo; así como las características demográficas de las usuarias, efectos adversos y efectividad anticonceptiva de cada método. Resultados: Luego de un año con el implante de ENG no se encontraron variaciones significativas respecto a las mediciones iniciales del peso corporal (61,21±8,30 vs. 61,23±9,50, p>0,5) e IMC (25,23±3.89 vs. 25,26 ±4,30; p>0,05); contrariamente, a lo observado entre las usuarias del DIU donde tanto el peso corporal como el IMC tuvieron un aumento significativo (P<0,05). Asimismo, la mayoría de las usuarias se mantuvieron en el mismo rango de peso donde se encontraban al iniciar el método (p<0,001); mientras que la ganancia ponderal fue mayor entre las usuarias del DIU (1,530±2,04 vs. 3,700±3,02; p<0,05). Conclusiones: El implante de ENG no produce aumento del peso corporal luego de 12 meses de uso, con mínimos efectos adversos y alta efectividad contraceptiva.

Aim: To analyse the effect on body weight of continuous hormonal contraception by releasing subdermal implant etonogestrel (ENG) in women of reproductive age treated in the family planning consultation of a Venezuelan hospital. Methods: Comparative and applied research, with quasiexperimental, case-control, open label and prospective design, with an intentional sample of 60 women separated to receive the contraceptive implant (Implanon NXT®; cases) or a cooper intrauterine device (IUD) (Cooper T; controls) was carried out. Body weight and body mass index were evaluated before and after 12 months of contraceptive use; as well as demographic characteristics of users, side effects, and contraceptive effectiveness of each method. Results: After one year with the ENG implant, no significant variations were found with respect to initial measurements of body weight (61.21±8.30 vs. 61.23±9.50, p>0.5) and BMI (25.23±3.89 vs 25.26±4.30; p>0.05); on the contrary, to what was observed among IUD users where both body weight and BMI had a significant increase (P<0.05). Likewise, most users remained in the same weight range as when starting the method (p<0.001); while weight gain was greater among IUD users (1,530±2.04 vs. 3,700±3.02; p<0.05). Conclusions: The ENG implant does not produce an increase in body weight after 12 months of use, with minimal adverse effects and high contraceptive efficacy.

Aplicación de PCR a partir de cultivo en la identificación de subespecies del complejo Mycobacterium Tuberculosis / The use of culture-based PCR for the identification of subspecies of the mycobacterium tuberculosis complex

Los métodos diagnósticos clásicos de tuberculosis (TB) se basan en la utilización de baciloscopía y cultivo. La identificación del agente etiológico desde la positivización del cultivo requiere entre 10 y 15 días, mientras que el empleo de la reacción en cadena de la polimerasa (PCR) disminuye el tiempo a 24 h, lo que permite no solo identificar las subespecies del complejo Mycobacterium tuberculosis (CMTB) sino también diferenciarlas de otras especies ambientales clínicamente importantes (MOTT) facilitando el diagnóstico y tratamiento. El objetivo del presente trabajo fue determinar la utilidad de la PCR en la identificación temprana de las micobacterias pertenecientes al CMTB, a partir de cultivos positivos, de pacientes con sospecha de TB, atendidos en un hospital pediátrico de alta complejidad, durante un período de cuatro años. A cada muestra, se le realizó baciloscopía y cultivo en medio líquido. A los cultivos positivos, una inmunocromatografía lateral (TBIDR) y luego PCR. El 4,6% del total de muestras (510/11.162) pertenecientes a 198 pacientes presentó cultivos positivos. Cuatrocientos veintiseis (84%) correspondieron a muestras respiratorias. El rendimiento de la baciloscopía directa fue del 41% (194/470). Cuatrocientos treinta y ocho (86%) resultaron M. tuberculosis, 21 (4%) Mycobacterium bovis, 7 (1%), M. bovis-BCG y 44 (9%) MOTT. La utilización de medios de cultivos líquidos junto con el empleo de PCR favorecen una rápida orientación microbiológica y constituye una estrategia útil para optimizar el manejo clínico de estas infecciones, desde el punto de vista terapéutico y epidemiológico, especialmente en pediatría (AU)

Classical diagnostic methods for tuberculosis (TB) are based on the use of smear microscopy and culture. The identification of the etiological agent from positive culture requires 10 to 15 days, while the use of the polymerase chain reaction (PCR) reduces the time to 24 h, which allows not only to identify the subspecies of the Mycobacterium tuberculosis complex (MTC) but also to differentiate them from clinically important environmental mycobacteria other than tuberculosis (MOTT), facilitating diagnosis and treatment. The aim of this study was to determine the usefulness of PCR in the early identification of mycobacteria belonging to the MTC, from positive cultures of patients with suspected TB seen in a pediatric tertiary hospital over a 4-year period. For each sample, smear microscopy and culture in liquid medium was performed. Positive cultures were subjected to lateral immunochromatography (TBIDR) and then PCR. Of the total number of samples (510/11,162) belonging to 198 patients, 4.6% showed positive cultures; 426 (84%) were respiratory samples. The direct smear microscopy yield was 41% (194/470). Overall, 438 (86%) were found to be M. tuberculosis, 21 (4%) Mycobacterium bovis, 7 (1%), M. bovis-BCG, and 44 (9%) MOTT. The use of liquid culture media together with the use of PCR favors a rapid microbiological orientation and is a useful strategy to optimize the clinical management of these infections, from a therapeutic and epidemiological point of view, especially in children (AU)

Factors associated with delayed diagnosis among sub-Saharan African women

Breast cancer incidence in sub-Saharan Africa is among the lowest in the world; however, mortality is as high as in high-incidence countries because of poor survival rates. Most breast cancer patients in sub-Saharan Africa are diagnosed at advanced stages after prolonged symptomatic periods. Understanding the reasons why women in sub-Saharan Africa seek care after the onset of symptoms is essential to promoting early diagnosis and ultimately improve their cancer survival.

Sub-Bowman keratomileusis versus femtosecond laser in situ keratomileusis on the long-term visual recovery: A comparative study

Purpose: To explore the long?term visual quality of the same subjects after sub?Bowman keratomileusis (SBK) or femtosecond laser in situ keratomileusis (FS?LASIK). Methods: This prospective study included patients screened for corneal refractive surgery at the Refractive Surgery Center of our Hospital between November 2017 and March 2018. One eye underwent SBK, while the other eye underwent FS?LASIK. Total higher?order aberrations, coma aberrations, and clover aberrations were evaluated before and at 1 month and 3 years after the procedure. The visual satisfaction of both eyes was investigated, respectively. The participants completed a surgical satisfaction questionnaire. Results: Thirty?three patients were included. There were no significant differences in total higher?order aberrations, coma aberrations, and clover aberrations between the two procedures before and 1 month and 3 years after surgery (all P > 0.05), except for the total coma aberrations in FS?LASIK were significantly higher compared with the SBK group at 1 month after surgery [0.51 (0.18, 0.93) vs. 0.77 (0.40, 1.22), P = 0.019]. The surgical satisfaction questionnaire scores of the SBK group and the FS?LASIK group were 9.8 ± 0.8 and 9.8 ± 0.8, respectively, at 1 month, and 9.7 ± 0.9 and 9.7 ± 1.0, respectively, at 3 years (all P > 0.05). Conclusion: There were no differences in corneal aberrations and satisfaction between SBK and FS?LASIK procedures at 1 month and 3 years.

Analysis of Otorhinolaryngology Practices-Challenges of Specialists and Facilties-in sub-Saharan Africa

Background: More than 95% of the population in sub-Saharan Africa (S.S.A.) does not have ready access to safe, affordable surgical care, and there is a desperate need for E.N.T. (ear, nose, and throat), audiology, and speech therapy services. Therefore, from an international outlook, the most significant challenge confronting hearing and cancer care delivery is not high-technology and high-cost medicine but the lack of access to even the most elementary E.N.T. care Materials and Methods: A literature search for studies on the analysis of trends and outcomes of otorhinolaryngology practices in sub-Saharan Africa was performed using Google Scholar search database, PubMed, Medline, and ScienceDirect. The bibliographies of included studies were also searched for additional references. About 95 articles were identified. Twenty-one articles were considered suitable for the review. The whole residents of the 22Results: countries illustrated in a study reviewed were 720,500,000; this symbolizes 75% of the population of sub-Saharan Africa. Among the 22 countries that were tested, 847 ENT surgeons, 580 audiologists, 906 speech therapists, 264 ENT clinical officers, and 320 oncologists were reported. When data have combined the sample, the regional ratio was 1.2 million people per E.N.T. surgeon, 0.8 million people per audiologist, and 1.3 million people per speech therapist. Conclusion: Basic E.N.T. and airway-related interventions are possible in most countries that responded; life-saving procedures such as tracheostomy (and tracheostomy tubes), bronchoscopy, and balloon dilatation were not readily available in all countries. Access to hearing screening was very poor in most countries, highlighting the undocumented burden of disease of hearing loss in Africa and other LMICs, estimated at 5% of the world's population

Epidemiological model for the construction of scenarios of the dissemination of COVID-19 in Codó-MA / Modelo epidemiológico para construção de cenários da disseminação da COVID-19 em Codó-MA / Modelo epidemiológico para la construcción de escenarios de la diseminación del COVID-19 en Codó-MA

Background and objectives: due to the increase in the number of cases of the new coronavirus in the city of Codó-MA, there was a need to carry out a study on the spread of COVID-19 in the municipality in order to have a better knowledge and understanding of the problem. A study was carried out on the spread of COVID-19 in the city of Codó-MA, comparing the quantitative data on the number of cases in 2020 and 2021 between May and July and using the epidemiological model Susceptible-Infectious-Isolated-Recovered (SIQR). Methods: we collected daily data from the epidemiological bulletins made available by the Municipal Health Department of Codó (SEMUS-Codó), we chose the SIQR compartmental model to carry out the simulations, we assumed hypotheses and estimated the parameters in order to design the scenarios. We simulated scenarios such as social distancing of healthy individuals and social isolation of infected individuals. Results: in early 2020, cases increased more frequently than in early 2021, and approximately 20% of those infected were in social isolation. According to projections, more than 80% of cases of COVID-19 were not accounted for in Codó. In 2021, there was greater underreporting than in 2020, approximately 82% and 85%, respectively. Conclusion: from the results, the authors conclude that the social isolation of those infected is a more efficient method to contain an epidemic than the total blockade of the population and that the high number of underreported cases is because most of these cases are asymptomatic.(AU)

Justificativa e objetivos: devido ao aumento do número de casos do novo coronavírus na cidade de Codó-MA, viu-se a necessidade para fazer um estudo sobre a propagação da COVID-19 no município para a ter melhor conhecimento e entendimento do problema. Foi realizado um estudo sobre a disseminação da COVID-19 na cidade de Codó-MA, sendo comparados os dados quantitativos dos números de casos nos anos de 2020 e 2021 entre os meses de maio e julho e utilizando o modelo epidemiológico Suscetíveis-Infecciosos-Isolados-Recuperados (SIQR). Métodos: coletamos os dados diários dos boletins epidemiológicos disponibilizados pela Secretaria Municipal de Saúde de Codó (SEMUS- Codó), escolhemos o modelo compartimental SIQR para a realização das simulações, supomos hipóteses e estimamos os parâmetros para podermos projetar os cenários. Simulamos cenários, tais como distanciamento social dos indivíduos sadios e isolamento social dos indivíduos infectados. Resultados: no início de 2020, os casos aumentaram com mais frequência do que no início de 2021, e aproximadamente 20% dos infectados estavam em isolamento social. De acordo com as projeções, mais de 80% dos casos de COVID-19 não foram contabilizados em Codó. Em 2021, houve maior subnotificação do que em 2020, aproximadamente 82% e 85%, respectivamente. Conclusão: a partir dos resultados, os autores concluem que o isolamento social dos infectados é um método mais eficiente para conter uma epidemia do que o bloqueio total da população e que o alto número de casos subnotificados são porque a maioria desses casos são assintomáticos.(AU)

Posterior sub-Tenon triamcinolone injection in the treatment of postoperative cystoid macular edema secondary to pars plana vitrectomy

Purpose: To evaluate the efficacy and safety of posterior sub?Tenon triamcinolone (PSTA) in chronic postoperative cystoid macular edema (PCME) after pars plana vitrectomy (PPV). Methods: Consecutive 22 patients who developed chronic PCME after PPV and underwent PSTA treatment were included in this retrospective study. Best?corrected visual acuity (BCVA) and central macular thickness (CMT) were measured pre injection and post injection at one month, three months, six months, and at last visit. The patients were divided into three groups according to the injection response status: complete, partial, and resistant. Results: The mean follow?up period was 26.4 ± 16.2 months after PSTA. According to pre?injection values, there was a significant improvement in the values of BCVA and CMT at the first, third, and sixth months and at the last examination (P < 0.05). In the final examination, PCME recovered completely in 12 patients, partially in 8 patients, and resistance was observed in 2 patients. Conclusion: Posterior sub?Tenon triamcinolone seems to be effective in chronic PCME following PPV.

Treatment of anterior shoulder instability by latarjet coracoid bone block: preliminary functional results in a subsaharan hospital

Background: The Latarjet technique aims to stabilize the shoulder by reconstructing the glenoid rim using a bone fragment taken from the coracoid bone and generally fixed to the anteroinferior part of the glenoid. The aim of this study was to assess the functional outcome of this type of treatment. Methods: This retrospective study was conducted in several health institutions in Ivory Coast from January 2008 to December 2013. Folders of 15 patients whose shoulders were treated by the Latarjet coracoid bone block procedure for anterior shoulder instability and were followed-up for a minimum of 10 years were retrieved and data collected. Functional outcomes were assessed by the Rowe score. The data were evaluated and analysed using Epi Info and Excel statistical software. Results: The functional assessment according to the Rowe score revealed three excellent results, nine good results, two average results and one poor result. One case of recurrence was observed in the postoperative period and required a revision. Conclusion: This study suggests that the Latarjet preglenoid bone block procedure is an effective surgical procedure for treating anterior shoulder instability. It allows for a significant improvement in functional outcomes as well as a satisfactory return to sporting activity.

Factors associated with anaemia in under-five children in Zambia: Secondary analysis of the 2021 Malaria Indicator Survey Data

Introduction:Anaemia is one of the major public health concerns in many developing countries including Zambia. Unless it is acute, the consequences of anaemia are not immediate but have long-term debilitating effects such as growth and intellectual retardation and as such it does not receive the necessary attention it deserves. This study set out to assess the prevalence and associated factors of anaemia in under-five children in Zambia. Methods:This study was a secondary analysis of the 2021 Malaria Indicator Survey. We extracted data from the data sets at the National Malaria Elimination Centre after obtaining permission from the Ministry of Health. The extracted data was analysed in STATA14, summarised in frequencies, cross-tabulations between independent variables and the outcome and multivariable logistic regression was used to assess the associations between variables and anaemia. Findings:The prevalence of anaemia was found to be 53.8%. Anaemia was found to be associated more with children below one year compared to older children, children whose household heads had no or only have primary education compared to those with secondary or tertiary education and in the northern parts of the country such as Luapula and Northern provinces compared to the southern province. Further anaemia was more common in those with malaria than those without malaria and those with febrile illnesses than those without febrile illnesses. In addition, anaemia was less common in those who slept under insecticide-treated nets. Conclusion: Anaemia in Zambia has been found to be higher than the average in Southern Africa, it is associated with younger age groups, poverty conditions and where diseases like malaria and other febrile illnesses are more common than where they are not. The use of interventions like insecticide-treated nets is associated with reduced prevalence of anaemia.

Profil lipidique associé à l'obésité chez les adolescents à Brazzaville, Congo / Lipid profile among obese adolescents in Brazzaville, Congo

Contexte & objectif. Les modifications lipidiques chez les enfants obèses en Afrique noire sont peu documentées. Les objectifs de la présente étude étaient de déterminer chez les adolescents obèses le profil lipidique, et analyser les associations entre quelques paramètres anthropométriques et lipidiques. Méthodes. L'étude transversale a été réalisée à Brazzaville auprès de 82 adolescents âgés de 11 à 18 ans, répartis en 45 sujets obèses, 17 en état de surpoids et 20 poids normal. Des mesures de la taille, du poids, du tour de taille, des plis cutanés sous-scapulaire et tricipital ont été effectuées. Des prélèvements sanguins ont permis de déterminer les concentrations en cholestérol total, cholestérol-LDL, cholestérol-HDL et triglycérides. Résultats. Les concentrations lipidiques notées chez les adolescents obèses étaient significativement supérieures à celles des sujets de poids normal : cholestérol total, 1,70 vs 1,59g/L ; cholestérol-LDL, 1,03 vs 0,88g/L ; triglycérides, 1,18 vs 0,86. Par contre, celles du cholestérol-HDL étaient significativement inférieures : 0,42 vs 0,51g/L. Une corrélation positive a été retrouvée entre le rapport tour de taille/taille et le cholestérol-HDL (r=0,75 ; p=0,031). Conclusion. Nos résultats soulignent la nécessité de renforcer la prise en charge des enfants obèses afin de prévenir les facteurs de risque potentiels des maladies cardiovasculaires à l'âge adulte

COVID-19 impacts on healthcare access in sub-Saharan Africa: an overview

Abstract This overview aimed to describe the situation of healthcare access in sub-Saharan Africa, excluding South Africa, during the COVID-19 pandemic. A PubMed® search from March 31, 2020, to August 15, 2022, selected 116 articles. Healthcare access and consequences of COVID-19 were assessed based on comparisons with months before its onset or an identical season in previous years. A general reduction of healthcare delivery, associated with the decline of care quality, and closure of many specialty services were reported. The impact was heterogeneous in space and time, with an increase in urban areas at the beginning of the pandemic (March-June 2020). The return to normalcy was gradual from the 3rd quarter of 2020 until the end of 2021. The impact of COVID-19 on the health system and its use was attributed to (a) conjunctural factors resulting from government actions to mitigate the spread of the epidemic (containment, transportation restrictions, closures of businesses, and places of entertainment or worship); (b) structural factors related to the disruption of public and private facilities and institutions, in particular, the health system; and (c) individual factors linked to the increase in costs, impoverishment of the population, and fear of contamination or stigmatization, which discouraged patients from going to health centers. They have caused considerable socio-economic damage. Several studies emphasized some adaptability of the healthcare offer and resilience of the healthcare system, despite its unpreparedness, which explained a return to normal activities as early as 2022 while the COVID-19 epidemic persisted. There appears to be a strong disproportion between the moderate incidence and severity of COVID-19 in sub-Saharan Africa, and the dramatic impact on healthcare access. Several articles make recommendations for lowering the socioeconomic consequences of future epidemics to ensure better management of health issues.

Effects of 0.05% cyclosporine eye drops(Ⅱ)on corneal nerves of patients with moderate to severe dry eye / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the efficacy of domestic cyclosporine A(CsA)in dry eye and its effect on sub-basal nerves(SBN)by observing quantitative and morphological changes in corneal SBN of patients with moderate to severe dry eye before and after the treatment with 0.05% CsA eye drops(Ⅱ).METHODS: In this prospective study, a total of 20 patients(20 eyes)with moderate to severe dry eye who admitted to the ophthalmology department of the Affiliated Eye Hospital of Nanchang University from December 2020 to January 2022 were selected. They were treated with domestic CsA and followed up for 3mo. Clinical evaluation was carried out at baseline and at 3mo after treatment. The changes in clinical symptoms, signs and morphology and quantity of SBN were observed.RESULTS: The ocular surface disease index(OSDI)score, the tear break-up time(TBUT), Schirmer Ⅰ, corneal fluorescein staining(CFS)score were significantly improved at 3mo after treatment. Confocal microscopy data analysis showed that SBN density increased from 13.49±5.43 mm/mm2 to 14.93±5.34 mm/mm2(P&#x0026;#x003C;0.001), nerve curvature scores decreased from 2.86±0.92 to 2.31±0.75(P&#x0026;#x003C;0.001), number of beaded structure decreased from 1.45±0.67/100μm to 1.07±0.45/100μm(P&#x0026;#x003C;0.001), and the number of dendritic cell(DC)decreased from 5.83±3.28 per frame to 3.67±2.24 per frame at 3mo after treatment(P&#x0026;#x003C;0.001). The number of DC was positively correlated with the number of branch nerves, the grade of nerve curvature and the number of nerve bead.(rs=0.27, P=0.045; rs=0.407, P&#x0026;#x003C;0.01; rs=0.486, P&#x0026;#x003C;0.01).CONCLUSIONS: Nerve injury was positively correlated with corneal inflammation caused by dry eye, and 0.05%CsA eye drops(II)could effectively inhibit inflammation and improve the morphology and quantity of corneal SBN. Observation of corneal SBN via in vivo confocal microscopy can be used as an effective method to evaluate the therapeutic effect of dry eye patients.

Macroscopic and mesoscopic biomechanical analysis of the bone unit in idiopathic scoliosis / 生物医学工程学杂志

To investigate the effects of postoperative fusion implantation on the mesoscopic biomechanical properties of vertebrae and bone tissue osteogenesis in idiopathic scoliosis, a macroscopic finite element model of the postoperative fusion device was developed, and a mesoscopic model of the bone unit was developed using the Saint Venant sub-model approach. To simulate human physiological conditions, the differences in biomechanical properties between macroscopic cortical bone and mesoscopic bone units under the same boundary conditions were studied, and the effects of fusion implantation on bone tissue growth at the mesoscopic scale were analyzed. The results showed that the stresses in the mesoscopic structure of the lumbar spine increased compared to the macroscopic structure, and the mesoscopic stress in this case is 2.606 to 5.958 times of the macroscopic stress; the stresses in the upper bone unit of the fusion device were greater than those in the lower part; the average stresses in the upper vertebral body end surfaces were ranked in the order of right, left, posterior and anterior; the stresses in the lower vertebral body were ranked in the order of left, posterior, right and anterior; and rotation was the condition with the greatest stress value in the bone unit. It is hypothesized that bone tissue osteogenesis is better on the upper face of the fusion than on the lower face, and that bone tissue growth rate on the upper face is in the order of right, left, posterior, and anterior; while on the lower face, it is in the order of left, posterior, right, and anterior; and that patients' constant rotational movements after surgery is conducive to bone growth. The results of the study may provide a theoretical basis for the design of surgical protocols and optimization of fusion devices for idiopathic scoliosis.

Analysis and thoughts on the settings of sub-campus of public hospitals directly under the National Health Commission of China / 中华医院管理杂志

Objective:To analyse the settings of sub-campus of public hospitals directly under the National Health Commission, so as to provide research reference and suggestions for further promoting the scientific and standardized construction of sub-campuses of public hospitals.Methods:Data before August 30, 2022 were collected from the official websites of the hospitals in question including their introduction, overview, navigation, news and other categories of information.Relevant literatures on multi-campus published by hospitals under the direct management of the National Health Commission were obtained from the China National Knowledge Network, which was identified by searching the keywords " sub or multi-campus hospital" with " author affiliation", using such search conditions as " MeSH major topic" or " title/keywords/abstract" of the studied hospitals in advanced search builder. Descriptive analysis and frequency analysis were conducted on the numbers, the construction reasons, geographical location, operation scale, characteristics and positioning of the sub-campuses in the studied hospitals.Results:Of the 44 such hospitals, 30 had a total of 50 sub-campuses in operation. Generally there were two modes of construction. 35 were newly constructed and 15 formed by mergers; 37 sub-campuses were built and put into operation since 2010. Sub-campuses were usually located in the same area of the main campus, with 11 in the same area of the same city and areas, 35 in different areas of the same city, and 4 in different cities; the average geographical distance between the sub-campus and the main hospital campus was 31.18 kilometers; 27 sub-campuses had beds ≤ 500, 12 sub-campuses had beds between 501-1 000, 11 had beds>1 000; 14 specialized sub-campuses and 31 out of the 35 comprehensive sub-campuses clearly indicating their characteristics of specialized departments, and 1 other (research institute areas with research beds).Conclusions:Future proofing is characteristic of these public hospitals in terms of their sub-campus construction, regional setting, planning and positioning, and functional layout. However, both government regulatory departments and public hospitals should comprehensively consider and make prudent decisions on the planning, investment, demonstration, layout, and other aspects of the construction of sub-campuses of hospitals.
