Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Sishen Pills and its separated prescriptions are classic prescriptions of traditional Chinese medicine to treat intestinal diseases. In this study, a high-performance liquid chromatography-electrospray ionization tandem mass spectrometry(HPLC-ESI-MS/MS) technology was used to identify the components of Sishen Pills, Ershen Pills, and Wuweizi Powder. The positive and negative ion sources of electrospray ionization were simultaneously collected by mass spectrometry. A total of 11 effective components were detected in Sishen Pills, with four effective components detected in Ershen Pills and eight effective components detected in Wuweizi Powder, respectively. To explore the effects of Sishen Pills and its separated prescriptions on the human intestinal flora, an in vitro anaerobic fermentation model was established, and the human intestinal flora was incubated with Sishen Pills, Ershen Pills, and Wuweizi Powder in vitro. The 16S rDNA sequencing technology was used to analyze the changes in the intestinal flora. The results showed that compared with the control group, Sishen Pills, and its separated prescriptions could decrease the intestinal flora abundance and increase the Shannon index after fermentation. The abundance of Bifidobacterium was significantly increased in the Sishen Pills and Ershen Pills groups. However, the abundance of Lactobacillus, Weissella, and Pediococcus was significantly increased in the Wuweizi Powder group. After fermentation for 12 h, the pH of the fermentation solution of three kinds of liquids with feces gradually decreased and was lower than that of the control group. The decreasing amplitude in the Wuweizi Powder group was the most obvious. The single-bacteria fermentation experiments further confirmed that Sishen Pills and Wuweizi Powder had inhibitory effects on Escherichia coli, Staphylococcus aureus, and Enterococcus faecalis, and the antibacterial activity of Wuweizi Powder was stronger than that of Sishen Pills. Both Sishen Pills and Ershen Pills could promote the growth of Lactobacillus brevis, and Ershen Pills could promote the growth of Bifidobacterium adolescentis. This study provided a more sufficient theoretical basis for the clinical application of Sishen Pills and its separated prescriptions.

OBJECTIVE: To explore and analyze the clinical efficacy of robotic-assisted versus traditional total hip arthroplasty. METHODS: A total of 186 patients with end-stage hip joint diseases treated from January 2023 to April 2025 were selected as the research subjects. Among them, 85 patients were screened out using propensity score matching and divided into two groups according to different treatment methods:manual total hip arthroplasty (mTHA) group (mTHA group) and robotic-assisted total hip arthroplasty (rTHA) group (rTHA group). In mTHA group, there were 50 patients, including 18 males and 32 females, age ranged from 37 to 78 years old with a mean of (60.12±10.93) years old;body mass index (BMI) ranged from 16.6 to 32.0 kg·m^-2 with an average of (23.98±3.78) kg·m^-2;27 cases involved the left hip, and 23 cases involved the right hip. In the rTHA group, there were 35 patients, including 14 males and 21 females, age ranged from 31 to 76 years old with an average of (57.14±12.18) years old;the BMI ranged from 17.1 to 33.0 kg·m^-2 with a mean of (22.76±2.54) kg·m^-2;13 cases involved the left hip, and 22 cases involved the right hip. The following parameters were analyzed and compared between the two groups:acetabular anteversion angle, acetabular abduction angle, difference in combined offset, difference in lower limb length, proportion of acetabula located in the Lewinnek safe zone after surgery, operation time, visual analogue scale (VAS) score, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, and Harris hip score (HHS). RESULTS: All patients were followed up for 3 to 9 months, with an average of (6.8±1.3) months. In rTHA group and mTHA group, the abduction angles were (40.73±4.62)° and (40.95±4.71)° respectively;the differences in combined offset were (0.42±0.28) mm and (0.60±0.23) mm respectively;the WOMAC scores were(20.9±5.4) and (20.2±4.6) respectively;and the VAS were (1.1±1.0) and (1.0±0.8) respectively. There were no statistically significant differences in the above indicators between the two groups (P>0.05). However, statistically significant differences were observed between the two groups in the following aspects(P<0.05):the differences in lower limb length were (3.17±0.15) mm and (5.28±0.47) mm respectively;the postoperative acetabular anteversion angles were(22.84±2.83)° and (25.72±3.29)° respectively;the HHS were (80.7±5.5) and (74.8±6.3) respectively;and the operation times were (148.20±46.82) minutes and (81.84±18.76) minutes respectively. CONCLUSION Robot-assisted total hip arthroplasty demonstrates superior implant accuracy and improved early functional recovery compared with traditional manual THA. Nevertheless, it is associated with significantly longer operation time. Long-term prosthesis survival rate requires further follow-up verification.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

ObjectiveThe scale of microalgae farming industry is huge. During farming, it is easy for microalgae to be affected by miscellaneous bacteria and other contaminants. Because of that, periodic test is necessary to ensure the growth of microalgae. Present microscopy imaging and spectral analysis methods have higher requirements for experiment personnel, equipment and sites, for which it is unable to achieve real-time portable detection. For the purpose of real-time portable microalgae detection, a real-time microalgae detection system of low detection requirement and fast detection speed is needed. MethodsThis study has developed a microalgae detection system based on deep learning. A microscopy imaging device based on bright field was constructed. With imaged captured from the device, a neural network based on YOLOv3 was trained and deployed on microcomputer, thus realizing real-time portable microalgae detection. This study has also improved the feature extraction network by introducing cross-region residual connection and attention mechanism and replacing optimizer with Adam optimizer using multistage and multimethod strategy. ResultsWith cross-region residual connection, the mAP value reached 0.92. Compared with manual result, the detection error was 2.47%. ConclusionThe system could achieve real-time portable microalgae detection and provide relatively accurate detection result, so it can be applied to periodic test in microalgae farming.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

BACKGROUND:Due to the mismatch between the design of the proximal femoral nail antirotation Asian version(PFNA-Ⅱ)and Asian population,extrusion of the proximal femoral intertrochanteric nail may occur in the treatment of femoral intertrochanteric fractures.The influence of the protruding length on the curative effect of the operation needs to be further discussed. OBJECTIVE:To quantitatively measure the protruding length of the proximal trochanter of the femur with intramedullary nail after PFNA-Ⅱ,and to analyze the effect of protruding length on the efficacy of PFNA-Ⅱ in the treatment of femoral intertrochanteric fractures. METHODS:Totally 68 patients with femoral intertrochanteric fractures treated with PFNA-Ⅱ internal fixation in the First Affiliated Hospital of Anhui Medical University were selected.The extramedullary process of the proximal trochanter of the femur was quantitatively measured on the anterior and posterior X-ray films of the hip joint within 6 months after operation.According to the existence of extrusion of the proximal trochanter intramedullary nail,the patients were divided into protruding group and non-protruding group.The data of sex,height,fracture type,length and diameter of the intramedullary nail,the position of screw blade in the femoral neck and protruding length of proximal greater trochanter were collected.The postoperative curative effect was judged by visual analog scale pain score and hip joint Harris score at 6 months after operation.The influence of protruding proximal trochanter of the PFNA-Ⅱ intramedullary nail on the operative effect was observed. RESULTS AND CONCLUSION:(1)There were significant differences in sexual characteristics between the protruding group and the non-protruding group(P=0.001).(2)According to AO/OTA classification,there were no significant differences in fracture type between the protruding group and the non-protruding group(P=0.289).(3)There was no significant difference in the length and diameter of the intramedullary nail between the two groups(P=0.067,P=1.000).(4)There was no significant correlation between the height of all patients and the length of the intramedullary nail(P=0.510),but there was a significant correlation between height and protruding length(P=0.034).There was no significant correlation between screw blade position and protruding length(P=0.968).(5)Six months after operation,there was no significant difference in the hip Harris score(P=0.373),but the visual analog scale pain score was significantly higher in the protruding group than that in the non-protruding group(P=0.000).(6)The results suggest that nail extrusion often occurs in the proximal greater trochanter when PFNA-Ⅱ is used in the treatment of intertrochanteric fractures in Asians.When the nail extended into the proximal soft tissue of the greater trochanter,patients complained of proximal greater trochanteric pain and the visual analog scale score of proximal greater trochanter pain in the patient was significantly higher than that in the non-protruding group.To be more suitable for the Asian population,we suggest that the PFNA-Ⅱ should be improved to further shorten the proximal nail end to obtain better clinical results of femoral intertrochanteric fracture fixation.

Objective:To study the relationship between the absorptive capacity of inpatients with infectious diseases and the structure of diseases in 65 secondary and tertiary general hospitals in Beijing,and to objectively analyze the current situation of space utilization of inpatients with infectious diseases,so as to provide data support for the formulation of relevant policies.Methods:The variability of spatial absorption capacity indicators for secondary and tertiary general hospitals in 6 urban districts and 10 suburbs were compared separately,and the correlation between the spatial absorption capacity of secondary and tertiary general hospitals and the structure of disease types was visualized and analyzed using quadrant bubble charts.Results:In terms of spatial absorption capacity,there was a statistically significant difference in the proportion of patients from suburban districts treated in the secondary and tertiary general hospitals in 6 urban districts of the Beijing(P=0.003),while there was no statistically significant difference in the proportion of patients from other districts treated in the secondary and tertiary general hospitals in 10 suburbs(P=0.336).The spatial absorption capacity and disease structure of the secondary and tertiary hospitals in 6 urban districts and the tertiary hospitals in 10 suburbs showed significant correlation,while the secondary hospitals in 10 suburbs showed no significant correlation.Conclusion:The tertiary general hospitals in 6 urban districts have superior infectious disease type structure indicators,with significantly stronger spatial absorption capacity and stronger correlation between these two,which plays the function of inpatient service of difficult and severe infectious diseases.Only the district hospitals in the outer suburbs can provide inpatient services for infectious diseases,and the number of cases admitted is large,which meets the needs of inpatient diagnosis and treatment of common infectious diseases in the district.It is necessary to strengthen the investment of infectious disease medical resources and capacity building in 10 suburban districts according to the actual situation.

Objective:The service capacity of infectious diseases department in Beijing secondary and tertiary general hospitals was quantitatively analyzed to provide objective data support for the construction of infectious diseases department.Methods:The scope of infectious diseases was defined by the DRG tool,and the service capacity of medical institutions was described by the Case Mix Index(CMI)and number of DRG groups.The differences in the service capacity of infectious diseases in 67 secondary and tertiary general hospitals in Beijing from 2016 to 2020 were analyzed by data visualization and generalized linear equation,and the disease structure of different hospitals at different levels was compared by selecting representative hospitals.Results:From 2016 to 2020,the mean CMI of tertiary hospitals ranged from 0.94 to 0.97,while that of secondary hospitals ranged from 0.70 to 0.72.From 2016 to 2019,the average number of DRG groups in tertiary hospitals ranged from 26.75 to 27.79,and the average number of DRG groups in secondary hospitals ranged from 15.32 to 15.77,and the average number of DRG groups in secondary and tertiary hospitals showed a significant decline in 2020.CMI and number of DRG groups had statistical significant difference at hospital level(P＜0.001),and number of DRG groups had statistical difference in time dimension(P＜0.001).Conclusion:The infectious disease service capacity of tertiary general hospitals is obviously stronger than that of secondary general hospitals,and the infectious disease medical service capacity of large tertiary hospitals is obviously ahead,while the overall service level of secondary hospitals is low.We should give full play to the advantages of top three hospitals to build a high ground for infectious disease department construction,and combine the spatial distribution of medical resources and demand characteristics to improve the infectious disease service capacity of secondary hospitals.
