OBJECTIVE To sort out reform policy for basic medical insurance designated retail pharmacy （referred to as designated retail pharmacy） in China， and to provide reference for the improvement of the policy under the new situation of mutual- aid mechanism for covering outpatient bills. METHODS The policy texts on designated retail pharmacies issued by ministries and commissions of the State Council and departments directly under the State Council were collected from December 1998 to June 2023. The content analysis and social network analysis were adopted to construct a three-dimensional analytical framework based on the policy subject， the policy tool， and the policy process， in order to quantitatively analyze the policies on reforming designated retail pharmacies. RESULTS & CONCLUSIONS The reform policy of designated retail pharmacies can be roughly divided into three stages： germination， exploration and development， and in-depth promotion. The use of policy tools is dominated by environment-oriented tools， and the cooperation network of policy subjects presents a “head-body-tail” chain structure. With the advancement of policy reforms， the number of policy subjects showed a trend of decline followed by growth， the number of policy documents showed an upward trend， emphasizing the use of tools such as the construction of the pharmacist system， the flow of prescriptions， the payment of medical insurance， and the management of “dual-channels” and “outpatient co-ordination”. It is suggested that in terms of policy formulation， all policy subjects should adhere to top-level design， grasp the characteristics of the stage of policy development， and adjust the use of policy tools according to local and timely conditions； we should also strengthen cooperation and communication， improve policy formulation efficiency， achieve policy coordination， and continuously improve policies for designated retail pharmacies.

BACKGROUND:Kinesio taping is often used for the treatment of various sports injuries.The methods of foot and ankle sports taping are complex and diverse.Among them,Fascia taping is applicable to a wider range of people and can be used for different foot posture types,but it still lacks of practical verification,and its specific biomechanical role is not clear. OBJECTIVE:To observe the changes in plantar pressure characteristics of subjects with different foot positions during walking and jogging after Fascia taping. METHODS:Thirty-seven young healthy subjects were recruited from the Yantai campus of Binzhou Medical University to conduct the test.They were scored according to the foot posture index-six items version,and were divided into the supination foot group,the neutral foot group,and the pronation foot group.The static foot morphological indexes(including navicular drop,arch height index,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch)and the pressure-time integral of each foot zone during walking and jogging were collected and calculated respectively before and after Kinesio taping.The specific biomechanical mechanism of Fascia taping was analyzed. RESULTS AND CONCLUSION:(1)General data:There was no statistical difference among the three groups of subjects in general data,such as gender,height,and body mass index(P>0.05).Before taping,there was a significant difference in the foot morphological indexes and the areas of the outer front foot,midfoot,and hindfoot between different foot posture groups(P<0.01).(2)Static foot morphological indexes:After taping,there was no statistically significant difference between the groups in navicular drop,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch(P>0.05),while there was still a significant difference between the groups in the arch height index(P<0.05).In the supination foot group,the arch height index increased slightly,but there was no significant difference before and after taping(P>0.05).In the pronation foot group,the navicular drop and arch height flexibility-longitudinal arch was significantly reduced,and the arch height index was increased.There was a significant difference before and after taping(P<0.05).(3)The index of plantar pressure during walking:After taping,there was no significant difference between the three groups in the area of lateral forefoot and medial midfoot(P>0.05).In the pronation foot group,the lateral load of the forefoot increased after taping(P<0.05).In the supination position group,the load of the lateral forefoot and midfoot regions increased significantly(P<0.05),while the difference in the rear foot region was not significant(P>0.05).(4)The index of plantar pressure during jogging:After taping,there was no statistically significant difference between groups in the lateral forefoot(P>0.05).In the pronation foot group,the load of the medial forefoot increased significantly(P<0.05).In the supination position group,the load of the lateral forefoot,the middle foot and the rear foot region increased significantly(P<0.05).(5)The results showed that the Fascia taping was suitable for different foot postures.It could not only correct the static foot structure of subjects with different foot postures,but also regulate the abnormal plantar pressure distribution during the dynamic activities of walking and jogging,and the load of the midfoot,forefoot,and hindfoot in the supination and pronation posture tended to normal foot posture load level.

BACKGROUND:During stair walking,different muscles work in concert and compensate for each other,and it is unclear whether weakened muscle strength actually affects stair fall risk in older adults.Real-time electromyographic signals from older adults during stair walking are used to reflect high fall risk in older adults during stair walking,which may further improve the accuracy of prediction methods. OBJECTIVE:To investigate the effects of aging on lower limb muscle activation in older adults during stair walking and to analyze the relationship between their muscle activation characteristics and stair fall risk. METHODS:Subjects were divided by age into an older group(n=19)and a younger group(n=18)group and were asked to walk on a 10-step staircase at a natural speed,incorporating surface electromyography acquisition technology,to capture surface electromyography signals during stair walking and calculate the root mean square(RMS)to analyze differences in muscle activation levels.Logistic regression analysis was utilized to establish a predictive model for stair fall risk in older adults by incorporating the lateral femoral and gastrocnemius muscle RMS.The discrimination of the model was evaluated by the receiver operating characteristic curve and area under the curve,and the fit of the model was evaluated using the Hosmer-Lemeshow test RESULTS AND CONCLUSION:Activation of the rectus femoris(Z=-3.464,P=0.001;t=3.379,P=0.002)and lateral gastrocnemius muscle(Z=-2.978,P=0.003;Z=-3.555,P<0.001)was higher in older adults than in younger adults when walking up and down stairs.Activation of the anterior tibialis(Z=-2.350,P=0.019)and medial(Z=2.321,P=0.020)and lateral(t=3.158,P=0.004)gastrocnemius muscles was higher in older adults when ascending stairs than descending stairs.Older adults at risk for falls had less activation of the lateral femoral muscle(Z=-2.613,P=0.009),medial gastrocnemius muscle(Z=-2.286,P=0.022)when walking upstairs,and lateral femoral muscle(Z=-2.368,P=0.018)when walking downstairs than did older adults not at risk for falls.The predictive ability,goodness of fit,and discrimination of the stair fall prediction model for older adults based on surface electromyography were good(P-value of 0.010 for the Omnibus test of the model coefficients,P-value of 0.214 for the Hosmer-Lemeshow test,and the area of the curve of the upper staircase lateral femoral muscle=0.856,P=0.009).(5)The model was modeled with a cut-off value of 38.64 for the upper staircase lateral femoral muscle RMS value and there was a 0.952-fold increase in the risk of staircase falls for each unit decrease in the upper staircase lateral femoral muscle RMS in older adults.

Nasopharyngeal carcinoma is a common malignant tumor in southern China, and its occurrence and development mechanism are still not fully understood. However, a large number of studies have shown that DNA methylation has important clinical application value in the screening, diagnosis, treatment and prognosis evaluation of nasopharyngeal carcinoma. DNA methylation affects the division cycle, growth, invasion and migration of nasopharyngeal carcinoma cells by regulating the transcription and protein expression levels of genes associated with tumorigenesis and development. In addition, there are significant differences in DNA methylation expression levels in different stages of nasopharyngeal carcinoma, which provides theoretical guidance and clinical reference for the early diagnosis, timely treatment and response evaluation of nasopharyngeal carcinoma. Current studies have shown that DNA methylation detection may provide a simple and efficient early screening method for nasopharyngeal carcinoma, and can also explore new ideas for the development of non-invasive screening methods.

Objective:To investigate the impact of the interval period between biopsy and MR examination on tumor detection and extraprostatic extension (EPE) assessment for prostate cancer (PCa) using multi-parametric MRI (mpMRI).Methods:The study was cross-sectional and retrospectively included 130 patients with PCa who underwent RP and preoperative systematic biopsies followed by mpMRI between January 2021 and December 2022 in the First Medical Center of Chinese PLA General Hospital. Patients were divided into 3 groups according to interval following biopsy (group A,<3 weeks, 31 cases; group B, 3-6 weeks, 67 cases; group C,>6 weeks, 32 cases). The percentages of hemorrhage volume in the total prostate were drawn on T 1WI and calculated. The junior, senior and expert radiologists independently localized the index lesions and calculated the accuracy for tumor detection, in addition to assessing the probabilities of EPE according to EPE grade. The correlation between the hemorrhage extent and interval was analyzed using the Spearman correlation coefficient. The accuracy for tumor detection was compared using χ2 test among groups. The diagnostic performance of the radiologists for EPE prediction was assessed using the receiver operating characteristic curve, and the differences between the corresponding area under the curve (AUC) were compared using the DeLong test. Results:The percentage of hemorrhage was correlated with the interval between biopsy and MR examination ( r=-0.325, P<0.001). The detection accuracy of junior radiologist was 83.9% (26/31), 76.1% (51/67), and 78.1% (25/32) in group A, B and C, respectively; no differences were observed in the detection accuracy among three groups ( χ2=0.76, P=0.685). The detection accuracy of senior radiologist was 83.9% (26/31), 80.6% (54/67), and 71.9% (23/32) in 3 groups with no differences ( χ2=1.53, P=0.464). The detection accuracy of expert radiologist was 80.6% (25/31), 77.6% (52/67), and 93.8% (30/32) with no differences ( χ2=3.95, P=0.139). The AUC (95% CI) for predicting EPE were 0.830 (0.652-0.940), 0.704 (0.580-0.809), 0.800 (0.621-0.920) in the group A, B and C for junior radiologist; 0.876 (0.708-0.966), 0.768 (0.659-0.863), 0.896 (0.736-0.975) for senior radiologist; and 0.866 (0.695-0.961), 0.813 (0.699-0.895), 0.852 (0.682-0.952) for expert radiologist, respectively. No differences were observed among the subgroups in each radiologist ( P>0.05). Conclusion:The interval period does not significantly affect the detection accuracy and EPE assessment of PCa using mpMRI. There is probably no necessity for prolonged intervals following systematic biopsy to preserve the clarity of MRI interpretation for PCa.

In the era of evidence-based medicine, it is necessary to explore the unique advantages of traditional Chinese medicine (TCM) based on standardized technical methods and operating procedures in order to achieve the modernization and internationalization of TCM and benefit all humanity. The proposal of a three-pronged evidence system combining TCM theory, human experience and experimental evidence marks an important progress in the thinking method of the TCM evaluation system. The multi-evidence body integrated through appropriate methods provides a strong support for the clinical guideline recommendations and evidence-based health decision-making in TCM. Based on the current methodological progress of international evidence synthesis and grading, this paper proposes a novel approach for integrating multi-evidence in TCM: the MERGE framework. The aim is to establish a solid foundation for the development of this methodology and provide guidance for the advancement of evidence-based medicine framework in TCM.

Purpose To explore the additional value of apparent diffusion coefficient(ADC)histogram in predicting extraprostatic extension(EPE)of prostate cancer.Materials and Methods Consecutive patients undergoing multi-parameter MRI and subsequent radical prostatectomy from January 2021 to December 2022 were retrospectively included in this study.Two radiologists independently estimated EPE by using national cancer institute grading system for extraprostatic extension(EPE grade system),with disagreement resolved by discussion.Histogram metrics were derived from three-dimensional volumes of interest encompassing the entire lesion on ADC maps using FireVoxel,obtaining mean ADC,1st,5th,10th,25th,50th,75th,90th,95th and 99th ADC values.The ADC histograms between the groups with and without EPE were compared.Multivariable Logistic regression analysis was used to identify the independent predictive factors of EPE,and a combined model was developed.Receiver operator characteristic curve was used to evaluate the diagnostic performance,and the area under the curve was calculated and compared.Results Thirty-four patients(34％)had pathologic confirmed EPE after radical prostatectomy.ADC histogram parameters showed significant differences between patients with and without EPE(P＜0.05).Multivariate Logistic regression analysis revealed 99th ADC(OR=0.609,P=0.008)and EPE grade system(OR=4.158,P＜0.001)were independent predictors of EPE.For predicting EPE,the area under the curve of 99th ADC,EPE grade system and the combined model were 0.756,0.805 and 0.856,respectively.The area under the curve of 99th ADC and the EPE grade system in identifying EPE showed no significant difference.The diagnostic efficacy of combined model was significantly superior to that of 99th ADC or EPE grading system(Z=2.223,2.208,both P＜0.05).Conclusion The ADC histogram parameters demonstrate additional value for preoperative prediction of EPE.Combining the 99th ADC histogram parameter with the EPE grade system may improve the diagnostic efficacy of EPE.

Methods: From May 2021 to August 2021, panelists were chosen to collect expert feedback using the modified Delphi method, and 74 spine surgeons from across China agreed to participate. Four rounds were conducted: one in-person meeting and three subsequent survey rounds. Each question received at least 70.0% agreement, indicating a consensus. The grade A, B, and C recommendation were defined as having ≥90.0%, 80.0%–89.9%, and 70.0%–79.9% agreement on each question, respectively. Results: The panelist group consisted of 74 experts, and 72, 70, and 69 questionnaires were collected in three rounds, respectively. In total, 24 questions with 59 options reached consensus after the Delphi rounds, including indications (adjacent vertebral diseases after lumbar internal fixation) and contraindications (previous surgery or bone destructive diseases lead to the destruction or absence of bone in the lamina or isthmus); advantages (intraoperative traction of paravertebral soft tissue is small) and disadvantages (not three-column fixation.); preoperative evaluation; complications; and postoperative follow-up evaluation, of CBT. Conclusions The modified Delphi method achieved expert consensus on the clinical use of CBT for lumbar pedicle screws. This consensus document establishes clear guidelines for indications, contraindications, surgical techniques, and postoperative management, thereby enhancing clinical decision-making and promoting the safe and effective use of CBT. While the initial study focused on Chinese surgeons, future research will seek to validate and expand these findings from a broader international perspective.

ObjectiveTo explore the effect of core stability training on dynamic balance and surface electromyography (sEMG) after anterior cruciate ligament reconstruction (ACLR), and to analyze the correlation between balance index and sEMG. MethodsFrom March to December, 2022, 32 patients with ACLR in Yantai Affiliated Hospital of Binzhou Medical University were randomly divided into control group (n = 16) and experimental group (n = 16). The control group accepted routine rehabilitation treatment, and the experimental group added core stability training, for six weeks. They were evaluated with American Hospital for Special Surgery Knee Score (HSS) and International Knee Documentation Committee Knee Score (IKDC), and the dynamic balance function and sEMG were measured before and after treatment, and the correlation between dynamic balance index and root mean square (RMS) of sEMG was analyzed. ResultsAfter treatment, the scores of HSS and IKDC increased significantly in both groups (|Z| > 3.526, |t| > 63.544, P < 0.001), and were better in the experimental group than in the control group (Z = -2.392, t = 2.650, P < 0.05); the length of gait line and single support line increased significantly, the medial-lateral displacement displacement decreased (|t| > 2.368, Z = -3.516, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.497, Z = -3.091, P < 0.05); the RMS of gluteus maximus and gluteus medius increased in the experimental group (t = -5.900, Z = -2.741, P < 0.01), and were better than those in the control group (t = 3.930, Z = -3.260, P < 0.01). After treatment, the RMS of gluteus maximus and gluteus medius in both groups were positively correlated with gait line length and single support line length, and were negatively correlated with medial-lateral displacement (|r| > 0.502, P < 0.01). ConclusionCore stability training could significantly improve knee joint function and dynamic balance, and enhance the activation of gluteus maximus and gluteus medius. Dynamic balance is highly correlated with sEMG.

Objective To analyze the role of preoperative peripheral blood inflammatory parameters and postoperative lymph-node ratio (LNR) in the prognosis of gastric cancer patients treated with chemotherapy. Methods The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune inflammatory response index (SII), lymphocyte-to-monocyte ratio (LMR), Onodera prognostic nutritional index (OPNI), and LNR of 108 patients with gastric cancer were classified into high and low groups to analyze their prognostic value on the overall survival (OS) of gastric cancer patients treated with chemotherapy. The independent prognostic indicators were plotted in columns to predict the survival rate of gastric cancer patients. Results NLR was statistically significant in the prognostic assessment of gastric cancer patients treated with chemotherapy (P < 0.001). Moreover, the high PLR group, high SII group, high LNR group, N3 stage, TNM (Ⅲ-Ⅳ) stage, nerve invasion, and carcinoembryonic antigen (CEA) were independent risk factors for the prognosis of gastric cancer (all P < 0.05). These findings indicated that in predicting the prognosis of gastric cancer, the combination of LNR, PLR, and SII (AUC=0.875) was better than that of LNR, PLR, and SII alone or in pairwise combination. Conclusion Elevated NLR, LNR, PLR, and SII are associated with significantly reduced survival of patients. LNR, PLR, and SII could be used as independent risk factors for the prognosis of gastric cancer patients treated with chemotherapy, and their combination can predict the survival of gastric cancer patients.
