Objective To construct an optimal prediction model of chickenpox in Urumqi, and to provide reference for formulating the prevention and control strategies of chickenpox. Methods The multivariate autoregressive moving average model (ARIMAX) and random forest model (RF) were established based on the monthly incidence of chickenpox in Urumqi from 2014 to 2018, and the monthly incidence of chickenpox in 2019 was used to test the models and evaluate their prediction effect. The prediction performance of the two models was compared, and the best model was selected to predict the incidence of chickenpox in Urumqi. Results The incidence of chickenpox in Urumqi showed a regular bimodal distribution with obvious seasonality, and it showed a slow upward trend from July 2014 to December 2019. The fitting model was ARIMA(0,1,0)(0,1,1)₁₂, the root mean square error (RMSE) and mean absolute error (MAE) of ARIMAX model training set were 1.29 and 0.95, respectively, and the RMSE and MAE of the test set were 1.88 and 1.44, respectively. The training set RMSE and MAE of RF model were 1.56 and 1.56, respectively, and the test set RMSE and MAE were 4.83 and 3.96, respectively. Conclusion The performance of ARIMAX model is better than that of RF model, which can better predict the incidence trend of chickenpox in Urumqi. It is necessary to optimize the prediction model according to the actual situation and provide scientific guidance for the prevention and control of chickenpox.

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.

Advancements in artificial intelligence (AI) and emerging technologies are rapidly expanding the exploration of chemical space, facilitating innovative drug discovery. However, the transformation of novel compounds into safe and effective drugs remains a lengthy, high-risk, and costly process. Comprehensive early-stage evaluation is essential for reducing costs and improving the success rate of drug development. Despite this need, no comprehensive tool currently supports systematic evaluation and efficient screening. Here, we present druglikeFilter, a deep learning-based framework designed to assess drug-likeness across four critical dimensions: 1) physicochemical rule evaluated by systematic determination, 2) toxicity alert investigated from multiple perspectives, 3) binding affinity measured by dual-path analysis, and 4) compound synthesizability assessed by retro-route prediction. By enabling automated, multidimensional filtering of compound libraries, druglikeFilter not only streamlines the drug development process but also plays a crucial role in advancing research efforts towards viable drug candidates, which can be freely accessed at https://idrblab.org/drugfilter/.

ObjectiveTo explore the mechanism of Cangxi Tongbi capsules （CXTB） in regulating the p38 mitogen-activated protein kinase （p38 MAPK）/NOD-like receptor protein 3 （NLRP3）/cysteine protease-1 （Caspase-1） signaling pathway to inhibit pyroptosis of cartilage cells in knee osteoarthritis （KOA）. MethodSixty male SD rats were randomly divided into a sham operation group， a model group， low， medium， and high dose CXTB groups， and a positive control group， with 10 rats per group. The modified Hulth method was employed to establish a rat model of KOA. According to their respective assignments， rats were administered CXTB （0.25， 0.5， 1.0 g·kg^-1） and Celecoxib （24 mg·kg^-1） by gavage. The sham operation and model groups were given an equivalent volume of physiological saline. Treatment was performed once daily for 28 days. Micro-computed tomography （Micro-CT） was used to assess bone volume/total volume （BV/TV） and trabecular separation （Tb.Sp）. Joint degeneration was evaluated through hematoxylin-eosin （HE） staining， safranin-fast green （SO） staining， and Osteoarthritis Research Society International （OARSI） scoring. Western blot analysis was conducted to measure the expression levels of p38 MAPK， phosphorylated p38 MAPK （p-p38 MAPK）， NLRP3， Caspase-1， and gasdermin D （GSDMD） proteins. Real-time PCR was used to assess mRNA expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD genes. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum concentrations of inflammatory cytokines including tumor necrosis factor-alpha （TNF-α）， interleukin-1 beta （IL-1β）， and interleukin-18 （IL-18）. After knee replacement surgery， cartilage tissue was analyzed using Western blot to assess the protein expression levels of p38 MAPK， p-p38 MAPK， NLRP3， Caspase-1， and GSDMD， and Real-time PCR was used to evaluate gene expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD. ResultMicro-CT analysis revealed significant narrowing of the joint space and increased bone spur formation in KOA rats compared with the sham operation group， with a decrease in BV/TV ratio and an increase in Tb.Sp value （P<0.01）. Serum levels of TNF-α， IL-1β， and IL-18 were elevated （P<0.01）. The protein expression levels of p-p38 MAPK， NLRP3， Caspase-1， and GSDMD in cartilage were significantly increased （P<0.01）， and the mRNA expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD were also enhanced （P<0.01）. Significant differences in protein expression of p-p38 MAPK， NLRP3， Caspase-1， and GSDMD were observed between normal and diseased cartilage tissues after knee replacement surgery （P<0.05）， and the gene expression of p38 MAPK， NLRP3， Caspase-1， and GSDMD were also significantly different （P<0.01）. HE and SO staining showed roughened joint surfaces， reduced cartilage thickness， and disordered cellular arrangement in KOA rats. OARSI scores were significantly higher （P<0.01）. Compared with the model group， treatment with low， medium， and high concentrations of CXTB resulted in increased BV/TV ratios and decreased Tb.Sp values in the knee joints of rats （P<0.01）. HE and SO staining indicated a trend towards smoother joint surfaces and reduced OARSI scores （P<0.01）. The protein expression levels of p-p38 MAPK， NLRP3， Caspase-1， and GSDMD were notably decreased （P<0.05）， as were the mRNA expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD （P<0.01）. Additionally， serum concentrations of TNF-α， IL-1β， and IL-18 were significantly reduced （P<0.01）. ConclusionCXTB intervention may alleviate knee joint degeneration in KOA rats and inhibit the expression of inflammatory factors and pyroptosis of cartilage cells， thereby protecting cartilage. The underlying mechanism may involve modulation of the p38 MAPK/NLRP3/Caspase-1 signaling pathway.

Objective:To investigate the basic characteristics and treatment of aseptic nonunion of femoral shaft in Xi'an Red Cross Hospital from 2013 to 2020.Methods:The data were analyzed retrospectively of the patients with aseptic nonunion of femoral shaft who had been treated at Department of Orthopaedics and Trauma, Red Cross Hospital Affiliated to Medical College, Xi'an Jiaotong University from January 2013 to December 2020. The patients' data from 2013 to 2016 were assigned into group A while those from 2017 to 2020 into group B. The data like gender, age and nonunion were statistically analyzed and compared between the 2 groups.Results:A total of 311 patients with aseptic nonunion of femoral shaft were diagnosed and treated during the 8 years, accounting for 54.6% (311/570) of the femur nonunion, 32.8% (311/949) of the lower extremity nonunion, 25.0% (311/1,242) of the extremity nonunion, and 22.7% (311/1,370) of the whole body nonunion. There were 244 males and 67 females; the majority of patients were in the age group of 21 to 50 (67.2%, 209/311). The occupation distribution was the most common in farmers (49.2%, 153/311). Traffic injury was the most common cause for primary fractures (40.8%, 127/311). The most common type of injury was closed injury (89.4%, 278/311); the most common type of nonunion was atrophic nonunion (87.8%, 273/311); intramedullary nailing was the main treatment for primary fractures (54.3%, 169/311); channel osteogenesis was the main treatment for secondary nonunion (62.1%, 193/311); autologous iliac bone grafting was the most common grafting for atrophic nonunion (83.5%, 228/311). Compared with group A, the proportion of aseptic nonunion of femoral shaft in group B increased by 9.2% in the femoral nonunions, by 6.9% in the lower extremity nonunions, and by 6.0% in the extremity nonunions, and by 5.2% in the whole body nonunions, showing statistically significant differences ( P < 0.05). There were significant differences in the types of nonunion, occupational distribution, first-stage fracture treatment, second-stage nonunion treatment, and bone grafting method between the 2 groups ( P < 0.05). Conclusions:The patients with aseptic nonunion of the femoral shaft were more common in young and middle-aged male heavy manual laborers, and the condition was increasing in recent years. The channel osteogenesis technique was still the preferred treatment method in the hospital investigated.

Non-coding RNAs (ncRNAs), which are thought to regulate articular cartilage through endochondral osteogenesis, consist of mRNA-interfering complementary RNA (miRNA) and long non-coding RNAs (lncRNA). More and more experimental evidence reveals the role of ncRNAs in chondrocyte differentiation and the pathogenesis of several skeletal diseases, including osteoarthritis. In the past few years, increasingly sophisticated DNA sequencing methods and a large number of sepigenetic modifications have greatly contributed to our understanding of the pathophysiological mechanisms of osteoarthritis. Recent studies have revealed that RNA interacts with RNA-binding proteins, regulates gene transcription and protein translation, and is involved in various pathological processes in OA, promising to be a therapeutic target for osteoarthritis.

Objective: To investigate the safety and effect of tranexamic acid combined with drainage tube clamping to reduce perioperative blood loss of Schatzker V and VI tibial plateau fracture. Methods: A prospective case-control study was performed on 87 patients with Schatzker V and VI tibial plateau fracture admitted from March 2018 to January 2019 in Honghui Hospital, including 53 males and 34 females, aged 24 to 69 years [(39.05±2.7)years]. All patients underwent tibial plateau reduction and internal fixation. According to the random number table method, the patients were divided into intravenous group (27 cases), articular cavity group (30 cases) and control group (30 cases). The intravenous group were given a total of 1 g of tranexamic acid intravenously 5-10 minutes before loosening the tourniquet, the joint cavity group were perfused with 1 g of tranexamic acid before closing the incision, and the control group were given the same amount of normal saline. The drainage tube was temporarily clamped for 4 hours in the three groups. Data were recorded and compared among the groups, including the surgical limb side, tourniquet use time, hemoglobin (Hb), D-dimer level, drainage, total blood loss, number of allogeneic blood transfusions, postoperative complications, and presence or absence of deep vein thrombosis (DVT) of the lower extremities at 72 hours after discharge. Results: There was no significant difference in baseline data between the three groups (P>0.05). There were no significant differences in the extremity side, tourniquet use time, and number of allogeneic blood transfusions among the three groups (P>0.05). At postoperative 24 hours, the Hb was (112.7±11.8)g/L in the intravenous group, (107.7±16.1) g/L in the articular cavity group, At (100.0±10.4) g/L in the control group. At postoperative 24 hours, the D-dimer vein was (5.5±2.9)mg/L in the intravenous group, (5.9±2.5)mg/L in the joint cavity group, and (7.5±3.6)mg/L in the control group. At postoperative 24 hours, the drainage volume was (62.8±20.5)ml in the intravenous group, (60.2±17.4)ml in the articular cavity group, and (81.2±21.1)ml in the control group. The hidden blood loss was (577.1±212.1)ml in the intravenous group, (634.2±139.8)ml in the articular cavity group, (750.3±124.1)ml in the control group. The total blood loss was (950.1±170.5)ml in the intavenous group, (1 005.4±179.8)ml in the articular cavity group, and (1 148.8±129.1)ml in the control group. The incidence of postoperative wound swelling and exudation was 1 case (4%) in the intravenous group, 0 cases in the articular cavity group, 5 cases (17%) in control group. The above indexes showed significant differences between the three groups (P<0.05 or 0.01), but there was no significant difference between the intravenous group and the articular cavity group (P>0.05). The Hb at 72 hours postoperatively, total drainage, number of allogeneic blood transfusions, lower extremity DVT and incidence of skin ecchymosis had no significant difference among the three groups(P>0.05). No pulmonary embolism occurred after the operation. Conclusions For patients with Schatzker V and VI tibial plateau fracture, tranexamic acid combined with drainage tube clamping is safe and effective when used perioperatively. Either intravenous infusion or local joint cavity injection of tranexamic acid can effectively reduce the drainage volume at 24 hours postoperatively, hidden blood loss and total blood loss without increasing the risk of postoperative DVT. Tranexamic acid can reduce the and exudation after operation.

Objective:To investigate the effects of surgical revision for humeral shaft nonunion on health-related quality of life.Methods:The data of 62 patients were studied retrospectively who had been hospitalized at Department of Orthopaedics and Traumatology, Hong-Hui Hospital for humeral shaft nonunion from March 2013 to September 2018. They were 43 males and 19 females, aged from 20 to 73 years (average, 42.3 years). Their nonunions belonged to the atrophic type in 19 cases, to the ischemic type in 14 cases and to the hypertrophic type in 29 cases. Their demographic and clinical data, imaging manifestations and treatment methods were recorded and analyzed. The 12-item short form health survey (SF-12) and brief pain inventory (BPI) were used to evaluate their health-related quality of life and the Mayo elbow performance score (MEPS) was used to evaluate their elbow function.Results:Upon admission, their physical component summary (PCS) scored 24.3±5.2, mental component summary (MCS) 26.3±3.8, brief pain inventory- severity (BPI-S) 6.5±1.9, and brief pain inventory-interference (BPI-I) 6.7±2.5. At 1-year follow-up, their PCS averaged 43.6±8.1, MCS 34.7±4.4, BPI-S 4.9±1.2, and BPI-I 4.4±1.4. There were statistically significant differences between preoperation and postoperation in the above 4 groups of indicators ( P<0.05). Their MEPS at the last follow-up revealed a 95.2% rate of excellent elbow function (59/62). By comparison with the literature data, their postoperative PCS scores were not significantly different from those for the patients with Barrentt＇s esophagus, primary hypertension, chronic obstructive pulmonary disease and silicosis ( P>0.05). There was no significant difference either in the postoperative MCS scores between them and stroke patients ( P>0.05). Conclusions:As a destructive chronic disease, humeral shaft nonunion has negative effects on physical and mental health and quality of life of the patients. Although the pain effect on the limb can be alleviated by surgical revision, the entire treatment may cause permanent psychological trauma to the patients.
