Objective:To systematically review the research progress in the evaluation of the integration of medical care and prevention in China.Methods:The keywords "medical care","prevention","public health", and "evaluate" were used to search in Chinese databases (CNKI, Wangfang and VIP Chinese Science and Technology Journal) and English databases (PubMed, Embase, Cochrane, and Web of Science) from March 17, 2009, to August 7, 2024. The language of studies was restricted to Chinese and English. The inclusion criteria were the integration of medical care and prevention occurring at one of the three dimensions, i.e., macro-system level, meso-institution and professional level and micro-service level. The study area should be located in China. The studies about theoretical exploration, policy analysis, and review of theory and practice in foreign countries regarding the integration of medical care and prevention and the article types of conference abstract, editorial, letter, and news were excluded. A total of 30 studies (in Chinese) were finally included. The definition of the integration of medical care and prevention, study design, evaluation objects, and specific evaluation indicators were compared and analyzed.Results:The evaluation objects of the included studies were mainly primary health staff and patients with chronic diseases in primary care. The study designs were mainly cross-sectional studies ( n=18) and controlled trials ( n=8). The included studies involved a total of 39 specific evaluation indicators at the macro-system level (5), meso-institutional level (8), professional level (11), micro-service level (12), and outcome level (3). Conclusion:Research on the integration of medical care and prevention is still in the development stage. The existing studies lack commonly recognized evaluation indicators regarding the integration of medical care and prevention.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective To explore the differences in scapular motion and shoulder function between patients suffering from rotator cuff tears(RCT)with and without type Ⅲ scapular dyskinesis(SD).Meth-ods Between September 2021 and March 2023,sixteen patients suffering from rotator cuff tears with SD(SD group)and 17 counterparts without SD(non-SD group)were recruited from the Sports Hospital of the General Administration of Sport of China.Their scapular motion was assessed by measuring three parameters in the X-rays,including scapular spine line(LSS),scapular upward rotation angle(SU-RA),and coracoid upward shift distance(CUSD).Moreover,their shoulder range of motion in flexion,abduction and external rotation were recorded,and further evaluated using the Pain Visual Analog Scale(VAS)and American Shoulder and Elbow Surgeons Score(ASES).Results No significant differenc-es were found between the two groups in the average score of SURA,CUSD and LSS at 0°～30° shoul-der abduction,or in that of CUSD and LSS at 60°～90°shoulder abduction.However,the average SU-RA score of the SD group at 60°～90°shoulder abduction was significantly greater than the other group(P<0.05).The shoulder ranges of motion during active flexion,abduction and external rotation were significantly smaller in the SD group than in the non-SD group(P<0.05).Moreover,the average VAS score in the SD group was significantly higher than the non-SD group(P<0.05),while the average ASES score was significantly lower than the latter group(P<0.05).Conclusions RCT patients type III SD exhibits greater scapular upward rotation during shoulder abduction compared to those without SD.Moreover,the former patients suffer from more severe pain and have worse shoulder range of motion and functional performance than the latter.

Objective:To explore the clinical outcomes of intraoperative fluoroscopy on femoral tunnel placement in treating professional snow sports athletes with anterior cruciate ligament (ACL) injury.Methods:A retrospective case series study was used to analyze the clinical data of 13 professional snow sports athletes with ACL injury treated in the National Institute of Sports Medicine, General Administration of Sport of China from January 2016 to January 2019. There were 5 males and 8 females, aged 16-27 years [(18.5±3.0)years]. Intraoperative lateral fluoroscopy combined with quadrant method was performed for the accurate femoral tunnel placement in single-bundle ACL reconstruction by using autologous hamstring tendon in all patients. KT1000 side-to-side difference (KT1000-ssd), pivot shift test, International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Marx activity scale and maximum extension and flexion resistance ratio of the involved and uninvolved knee were compared before operation (or before injury) and at 3, 6, 12 and 24 months after operation. Whether returning to the field, time taken in returning to the field and re-injury were recorded at each follow-up visit. ACL graft signal intensity ratio (SIR) in MRI of the involved knee was evaluated at postoperative 24 months.Results:All patients were followed up for 24-33 months [(25.8±2.7)months]. There were 7 patients with KT1000-ssd degree I, 5 with degree II and 1 with degree III before operation, compared to 12 patients with KT1000-ssd degree 0 and 1 with degree I at 3 and 6 months after operation and 13 patients with KT1000-ssd degree 0 at 12 and 24 months after operation. The pivot shift test was grade I in 8 patients and grade II in 5 before operation, compared to 11 patients with degree 0 and 2 with degree I at 3 months after operation and 12 patients with degree 0 and 1 with degree I at 6, 12 and 24 months after operation. IKDC subjective score was (68.0±4.3)points, (84.7±7.9)points, (94.6±3.3)points and (96.5±1.8)points at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, IKDC subjective score was significantly improved compared to the preoperative (48.3±25.0)points (all P<0.01). The Lysholm score was (63.4±6.6)points, (80.1±6.5)points, (93.8±4.6)points and (96.5±2.4)points at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the Lysholm score was significantly improved compared to the preoperative (47.5±29.4)points (all P<0.01). The Marx activity scale was (7.4±0.5)points, (13.8±0.7)points, (14.6±0.8)points and (15.0±0.7)points at postoperative 3, 6, 12 and 24 months, respectively, significantly lower than (16.0±0.0)points before the injury (all P<0.01). The maximum extension resistance ratio of the involved and uninvolved knee was 0.60±0.10, 0.85±0.08, 0.91±0.06 and 0.97±0.04 at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the maximum extension resistance ratio of the involved and uninvolved knee was significantly increased compared to the preoperative 0.57±0.18 (all P<0.01).The maximum flexion resistance ratios of involved and uninvolved knee were 0.64±0.09, 0.82±0.06, 0.89±0.04 and 0.94±0.06 at postoperative 3, 6, 12 and 24 months, respectively. Six months after operation, the maximum flexion resistance ratio of the involved and uninvolved knee was significantly increased compared to the preoperative 0.60±0.12 (all P<0.01). Thirteen athletes returned to the field within 12 months after operation with the time taken in returning to the field ranging from 5-12 months [(8.7±1.9)months]. There was no ACL re-injury at postoperative 24 months. The ACL graft SIR in MRI of the involved knee was 1.80±0.20 at postoperative 24 months. Conclusion:Intraoperative fluoroscopy on femoral tunnel placement in the treatment of professional snow sports athletes with ACL injury can significantly improve the knee joint stability, subjective function, sports performance and muscle strength within 6 months, and can help them return to the field within 12 months, and accelerates graft healing.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.

Objective:To investigate the diagnostic value of synthetic MRI methods in the differentiation of benign and malignant breast lesions.Methods:Clinical and imaging data of 93 breast patients confirmed by pathology in the Second Affifiliated Hospital of Xi′an Jiaotong University from May 2019 to April 2020 were analyzed retrospectively. All patients underwent synthetic MRI technique, and the quantitative parameters of T 1, T 2, and proton density (PD) values were measured. Independent samples t-test and Wilcoxon test were used to compare the differences in clinical and imaging characteristics between the benign and malignant breast lesions. ROC curve was used for the comparison of the diagnostic efficacy of the quantitative parameters in differentiating malignant from benign breast lesions. Results:Of the 93 patients with breast lesions, 62 cases were malignant and 31 cases were benign. The quantitative T 2 values for benign and malignant lesions were 103 (93, 126)ms and 83 (77, 90)ms respectively, and the quantitative PD values were 87.7 (72.7, 96.7)pu and 73.5(63.3, 79.4)pu respectively. There were statistically significant differences between benign and malignant lesion( P<0.05). Taking quantitative T 2 values of 90.5 ms and PD values of 84.8 pu as the cut-off value, the area under the ROC curve in differentiating benign from malignant breast lesions were 0.87 and 0.75, accuracy values were 80.6% and 78.5%, specificity values were 87.1% and 54.8%, sensitivity values were 77.4% and 90.3% respectively. Conclusion:Synthetic MRI methods can be applied in the examination of breast lesions and has the potential to be an effective diagnostic method for the differential diagnosis between benign and malignant lesions of breast.

The corona virus disease 2019 (COVID-19), which started in Wuhan in December 2019, is a new infectious disease. The disease is highly contagious, and the correct selection of effective disinfectants is essential. This article analyzed the environmental resistance of coronavirus and its sensitivity to commonly used disinfectants by reviewing domestic and foreign literatures, and concluded that coronavirus has strong survivability in the environment, but it can be efficiently inactivated by most disinfectants. However, it should be noted that the commonly used concentration of chlorine-containing disinfectants (effective chlorine concentration of 500 mg/L) cannot quickly kill coronavirus, and a concentration of 1 000 mg/L or higher is required. Other biocidal agents, such as benzalkonium chloride and chlorhexidine digluconate, are less effective. This article aimed to provide references for selecting the appropriate disinfectants and disinfection methods to cut off the spread of the virus.

Objective: To evaluate the predictive value of cervical size change rate and morphological distribution detected by ultrasound in the second trimester of pregnancy for preterm delivery. Methods: From June 2016 to June 2018, 300 pregnant women who underwent antenatal testing and gave birth in , the Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were selected in this research.The length, width and shape of cervix were measured by transvaginal color doppler ultrasonography at 14 and 28 weeks respectively.According to whether or not premature delivery occurred, they were divided into premature delivery group and full-term delivery group.The differences of cervical length, cervical inner mouth width, cervical length shortening rate, cervical inner mouth width increasing rate and cervical shape distribution between preterm and full-term pregnant women were compared, and the correlation between the above indicators and the occurrence of premature delivery were analyzed. Results: The length of cervix in the preterm delivery group [(21.41±6.28)mm] was significantly shorter than that in the full-term delivery group at 28 weeks of gestation [(34.17±5.76)mm](t=10.295, P=0.000), and the width of cervical inner mouth in the preterm delivery group [(9.54±2.57) mm] was significantly longer than that in the full-term delivery group [(4.06±0.91)mm] (t=25.416, P=0.000). The shortening rate of cervical length [(39.28±8.65)%] and the increasing rate of cervical width [(149.74±15.09)%] in the preterm pregnant women during the second trimester were significantly higher than those in the full-term pregnant women [(10.15±5.29)% and (16.33±3.84)%] (t=21.471, 39.420; P=0.000, 0.000). The proportion of T-type cervix in the preterm delivery group (77.17%) was significantly higher than that in the full-term delivery group (63.28%) (χ²=10.935, P=0.001). According to the correlation analysis, the length of cervix was negatively correlated with premature birth (r=-0.612, P=0.035), and the width of cervical inner mouth, the shortening rate of cervical length in the second trimester and the increasing rate of cervical inner mouth width in the second trimester were positively correlated with premature birth (r=0.743, 0.665, 0.807; P=0.013, 0.026, 0.004). Conclusion Ultrasound monitoring of cervical size change rate and cervical morphology during the second trimester of pregnancy is helpful to the early prediction of preterm labor, which should be paid attention to clinically.
