Objective:This study aims to develop a validated instrument for assessing the degree of integration perceived by patients in the services provided by general practitioner(GP)teams,and to evaluate the current state of integrated medical-prevention services.Methods:The survey tool was initially created through a review of existing literature and semi-structured interviews.It was subsequently refined and enhanced following consultations with experts.The utility of the instrument was confirmed through empirical research,which also facilitated an analysis of the status quo regarding the integration of medical and prevention services.Results:The devised instrument encompasses 18 items distributed across six dimensions:service comprehensiveness,service continuity,depth of service,continuity of relationship,patient-centricity,and service coordination.The cumulative score reflecting patients'perception of the integration level in GP teams'medical-prevention services was 54.30±12.45.Conclusion:The survey instrument developed in this research is characterized by its rationality,novelty,and practical relevance.It offers a patient-centered perspective for assessing the quality of integrated medical and prevention services for primary chronic diseases.While the overall perception of integration among patients is positive,there is a notable deficiency in the depth of services provided.There is a need for optimization of the service process,clarification of the service path,refinement of service management,and development of an integrated incentive mechanism for medical and preventive care,aiming for a deeper integration between medical services and preventive care.

Objective To investigate the value of the human chorionic gonadotropin(hCG)stimulation test in the diagnosis of disorder of sexual development(DSD)in children.Methods A retrospective analysis was conducted on 132 children with DSD.According to the karyotype,they were divided into three groups:46,XX group(n=10),46,XY group(n=87),and sex chromosome abnormality group(n=35).The above groups were compared in terms of sex hormone levels before and after hCG stimulation test,and the morphological manifestation of the impact of testicular tissue on the results of the hCG stimulation test was analyzed.Results There was no significant difference in the multiple increase of testosterone after stimulation among the three groups(P>0.05).In the 46,XY group,the children with 5α-reductase type 2 deficiency had a testosterone-to-dihydrotestosterone ratio higher than that of the 46,XY DSD children with other causes.Morphological analysis showed that DSD children with testicular tissue demonstrated a significantly higher multiple increase in testosterone after stimulation compared to children without testicular tissue(P<0.05).Conclusions The hCG stimulation test has an important value in assessing the presence and function of testicular interstitial cells in children with different types of DSD,and it is recommended to perform the hCG stimulation test for DSD children with unclear gonadal type.[Chinese Journal of Contemporary Pediatrics,2024,26(2):158-163]

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

Objective To summarize the epidemiological and clinical features of infectious diseases of the central nervous system(CNS)by a single-center analysis.Methods A retrospective analysis was conducted on the data of 1247 cases of CNS infectious diseases diagnosed and treated in the First Medical Center of PLA General Hospital from 2001 to 2020.Results The data for this group of CNS infectious diseases by disease type in descending order of number of cases were viruses 743(59.6％),Mycobacterium tuberculosis 249(20.0％),other bacteria 150(12.0％),fungi 68(5.5％),parasites 18(1.4％),Treponema pallidum 18(1.4％)and rickettsia 1(0.1％).The number of cases increased by 177 cases(33.1％)in the latter 10 years compared to the previous 10 years(P<0.05).No significant difference in seasonal distribution pattern of data between disease types(P>0.05).Male to female ratio is 1.87︰1,mostly under 60 years of age.Viruses are more likely to infect students,most often at university/college level and above,farmers are overrepresented among bacteria and Mycobacterium tuberculosis,and more infections of Treponema pallidum in workers.CNS infectious diseases are characterized by fever,headache and signs of meningeal irritation,with the adductor nerve being the more commonly involved cranial nerve.Matagenomic next-generation sequencing improves clinical diagnostic capabilities.The median hospital days for CNS infectious diseases are 18.00(11.00,27.00)and median hospital costs are ￥29,500(￥16,000,￥59,200).The mortality rate from CNS infectious diseases is 1.6％.Conclusions The incidence of CNS infectious diseases is increasing last ten years,with complex clinical presentation,severe symptoms and poor prognosis.Early and accurate diagnosis and standardized clinical treatment can significantly reduce the morbidity and mortality rate and ease the burden of disease.

Objective:To compare the clinical efficacy of arthroscopic partial and complete repair for massive rotator cuff tears.Methods:A total of 32 patients who underwent arthroscopic partial repair of massive rotator cuff tears in the Department of Sports Medicine, Peking University Third Hospital from March 2016 to December 2019 were retrospectively analyzed, including 15 males and 17 females, aged 62±6.8 years (range, 51-77 years), with 5 cases on the left side and 27 cases on the right side. Cause of injury: 4 cases were injured by car accident, 8 were injured by fall, and 20 had no obvious cause. 32 patients who underwent arthroscopic complete repair of massive rotator cuff tears during the same period were included according to a sample size of 1∶1 matched based on age, sex, tear size and fat infiltration index. Clinical outcomes were evaluated using the visual analogue scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) shoulder score, Simple Shoulder Test (SST) score, and range of motion. Fatty infiltration and cuff healing were assessed using the Goutallier and Sugaya classifications on MRI, respectively.Results:All patients successfully completed the surgery and were followed up for 46.1±11.3 months (range, 36-72 months). Preoperative and final follow-up VAS scores were 6.6±1.8 and 1.6±1.1 in the complete repair group, and 6.4±1.9 and 1.4±1.3 in the partial repair group. Both groups showed significant postoperative improvement ( P<0.05), with no significant difference between groups at the final follow-up ( t=-0.729, P=0.468). The ASES score, UCLA shoulder score, and SST at the final follow-up were 81.7±6.5, 28.6±2.9, and 9.8±2.5, respectively, in the complete repair group, and 82.4±7.3, 28.1±2.6, and 9.1±1.9 in the partial repair group, and the difference between the groups was not statistically significant ( P>0.05). In the complete repair group, one case underwent reverse shoulder replacement for rotator cuff re-tear two years after surgery, and one case developed pseudoparalysis for rotator cuff re-tear 8 months after surgery but had no significant pain and did not receive further treatment; in the partial repair group, two cases underwent tendon transposition surgery for shoulder pain. Conclusion:Arthroscopic partial repair improves shoulder function and reduces pain in patients with massive rotator cuff tears, with similar efficacy to complete repair and has high surgical safety.

AIM: To investigate the effect of Nd:YAG laser peripheral iridotomy(LPI)on macular retinal thickness in patients with primary angle-closure glaucoma(PACG).METHODS: Prospective study. A total of 30 patients(30 eyes)with PACG in our hospital from October 2019 to October 2021 were selected as the PACG group, and 20 healthy people(20 eyes)were selected as the control group(randomly selected one eye)during the same period. The PACG group received LPI treatment and was followed up for 1mo after surgery. Best corrected visual acuity(BCVA), intraocular pressure, corneal endothelial cells, anterior chamber depth(ACD)and axial length(AL)measured by IOL Master 500 optical measuring instrument and macular retinal thickness measured by spectral-domain optical coherence tomography(SD-OCT)in both groups were collected. The ACD, intraocular pressure, AL and macular retinal thickness were compared between the two groups and the PACG group before and after LPI, and the correlation was analyzed.RESULTS: The ACD in the PACG group at 1wk and 1mo after surgery was deeper than that before surgery(all P<0.05). There was no significant difference in intraocular pressure and AL in the PACG group before and after surgery(all P>0.05). The retinal thickness at central fovea of macula, the superior side, temporal side, inferior side, and nasal side of the inner and outer central macular rings were 243.50±13.24, 324.50±13.46, 308.83±15.94, 310.00±14.24, 314.50±16.29, 300.67±19.95, 290.17±12.58, 302.40±16.37 and 307.33±14.84μm in the PACG group, respectively, and were 266.14±16.16, 342.67±15.86, 327.95±16.41, 337.85±13.03, 341.24±15.58, 313.76±17.59, 290.24±16.29, 303.81±13.91, 323.01±14.80μm in the control group, respectively. The differences at central fovea of macula, the superior side, temporal side, inferior side, and nasal side of the inner central macular rings were statistically significant between the two groups(all P<0.05). In the PACG group, the retinal thickness at 9 areas of macular in 1wk after operation were higher than those before operation, and they were close to the preoperative level at 1mo after operation, but the differences of each area in the overall comparison were not statistically significant(all P>0.05).CONCLUSIONS: The macular retinal thickness of patients with PACG is thinner than that of normal people, and it can become thicker in the early stage after LPI.

Objective: To examine the association of greenness exposure with waist circumference (WC) and central obesity in older adults in China. Methods: Based on the cross-sectional data from the Chinese Longitudinal Healthy Longevity Survey in 2017-2018, 14 056 participants aged 65 years and over were included. Demographic characteristics, lifestyle, WC, and other information were collected through a questionnaire and physical examination. Based on the satellite monitoring data of moderate-resolution imaging spectroradiometer (MODIS) provided by NASA, the annual mean of normalized difference vegetation index (NDVI) within a radius of 1 000 meters was obtained as the measurement value of greenness exposure. Multivariate linear regression model, multivariate logistic regression model, and restricted cubic splines (RCS) model were used to analyze the association and dose-response relationship between greenness exposure and WC and central obesity in older adults in China. Results: A total of 14 056 participants were enrolled with a median age of 84.0 years [IQR: 75.0-94.0 years]. About 45.0% (6 330) of them were male and 48.6% (5 853) were illiterate. There were 10 964 (78.0%) participants from rural. The mean of WC was (84.4±10.8) cm. Central obesity accounted for 60.2% (8 465), and the NDVI range was (-0.06, 0.78). After adjusting for confounding factors, the multivariate linear regression model showed that the change value of WC in the urban group [β (95%CI):-0.49 (-0.93, -0.06)] was smaller than that in the rural [-0.78 (-0.98, -0.58)] for every 0.1 unit increase in NDVI (P_interaction=0.022). Compared with the Q₁ group in NDVI, WC of Q₂ and Q₃ groups in rural decreased, and the β (95%CI) values were-1.74 (-2.5, -0.98) and-2.78 (-3.55, -2.00), respectively. The multivariate logistic regression model showed that after adjusting for confounding factors, the risk of central obesity decreased for urban and rural older adults with an increase of 0.1 unit in NDVI, and the OR (95%CI) values were 0.87 (0.80, 0.95) and 0.86 (0.82, 0.89), respectively (P_interaction=0.284). Compared with the Q₁ group in NDVI, the risk of central obesity in the Q₂ and Q₃ groups in rural was lower, and the OR (95%CI) values were 0.68 (0.58, 0.80) and 0.57 (0.49, 0.68), respectively. The results of the multivariate regression model with RCS showed that there was a non-linear association of NDVI with WC (P_nonlinear=0.006) and central obesity (P_nonlinear=0.025). Conclusion: Greenness exposure is negatively associated with WC and central obesity in older adults in China.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
