OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed， Embase， Web of Science， CNKI， Wanfang data， VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature， extracting data， and evaluating the quality of the literature， descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included， involving 12 models. Nine studies used Logistic regression algorithm for modeling， and the number of included predictive factors ranged from 3 to 11； the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias； 10 studies had high applicability risk. A total of 31 predictive factors were extracted， including 15 items of basic patient information， 3 test indicators， and 5 items of medication information， and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm， with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved， and the overall risk of bias is relatively high.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

ObjectiveTo investigate the effect and mechanism of Qingre Sanzhuo decoction in treating gouty arthritis （GA） combined with hyperuricaemia （HUA）. MethodsSixty male SD rats were randomized into normal， model， colchicine （0.5 mg·kg^-1）， and low-， medium-， and high-dose （17， 34， 68 g·kg^-1， respectively） Qingre Sanzhuo decoction groups （n=10）. The rats in other groups except the normal group were treated with the modified method for the modeling of GA combined with HUA. The drug intervention groups were administrated with corresponding drugs by gavage in the afternoon every day and the normal group and the model group were administrated with an equal volume of sterile normal saline by gavage. The level of uric acid （SUA） in the serum was measured 2 h after the last administration. The degree of ankle joint swelling was calculated 0.5， 12， 24， 48 h after modeling， and joint inflammation was scored. The pathological changes of ankle joints were observed by hematoxylin-eosin staining， and the serum levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， C reactive protein （CRP）， and interleukin-18 （IL-18） were measured by enzyme-linked immunosorbent assay. Real-time PCR was performed to determine the mRNA levels of NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing CARD （ASC）， cysteinyl aspartate-specific protease-1 （Caspase-1）， gasdermin D （GSDMD）， and nuclear factor-kappa B （NF-κB） in the synovial tissue of ankle joints. Western blot was employed to determine the protein levels of NLRP3， ASC， and Caspase-1 in ankle joints. The immunohistochemical method was used to detect the expression of GSDMD and NF-κB in the synovial tissue of ankle joints. ResultsCompared with the normal group， the model group showed increased SUA in the serum （P<0.05）， ankle joint swelling and joint inflammation （P<0.05）， increased number of blood vessels in the synovium， inflammatory cell foci in the synovial bursa， elevated serum levels of TNF-α， IL-1β， CRP， and IL-18 （P<0.05）， and up-regulated mRNA and protein levels of NLRP3， ASC， Caspase-1， GSDMD， and NF-κB in the synovial tissue of ankle joints （P<0.05）. Compared with the model group， the medium- and high-dose Qingre Sanzhuo decoction groups showed reduced SUA in the serum （P<0.05）， alleviated ankle joint swelling and joint inflammation （P<0.05）， lowered serum levels of TNF-α， IL-1β， CRP， and IL-18 （P<0.05）， and down-regulated mRNA and protein levels of NLRP3， ASC， Caspase-1， GSDMD， and NF-κB in the synovial tissue of ankle joints （P<0.05）. However， in terms of ameliorating the pathological changes of ankle joints， only the high-dose Qingre Sanzhuo decoction group showed normal morphology of the synovial membrane of ankle joints and no obvious lesion in the articular cartilage. ConclusionQingre Sanzhuo decoction may play a role in preventing and controlling GA combined with HUA by down-regulating the activity of NLRP3/ASC/Caspase-1 pathway and inhibiting the expression of inflammatory cytokines， such as TNF-α， IL-1β， CRP， and IL-18.

In traditional clinical teaching of impacted tooth extraction, there are problems including limited observation fields for students, insufficient doctor-patient communication training, inadequate clinical thinking development, and low levels of clinical participation. Based on the core elements of visualizing jaw structure with perspective, formulating clinical strategy, immersing in clinical participation, and cultivating the spirit of caregiving, we developed a virtual reality simulation teaching platform for the clinical decision analysis of impacted tooth extraction. The virtual simulation-based platform can create three different impacted tooth scenarios in 3D, which demonstrates the process of clinical decision analysis of impacted tooth extraction through virtuality-reality interaction, allowing students to immerse in the discovery, analysis, and resolution of the medical and humanistic problems in the process of impacted tooth extraction. The questionnaire survey showed that 81.36% (48/59) of the students believed that the software could improve their clinical thinking ability; 76.27% (45/59) of the students believed that it could help them master the basic process of impacted tooth extraction; and 62.71% (37/59) of the students believed that it could improve their skills of impacted tooth extraction. By providing immersive learning experience, constructive teaching design, and multi-dimensional teaching evaluation, the software achieved the goals of cultivating students' clinical thinking ability and professional literacy in oral and maxillofacial surgery.

AIM:To investigate the inhibitory ef-fect of Zushima ointment on inflammation and bone destruction in CIA mice.METHODS:SPF grade male DBA/1 mice were used,6 were random-ly selected as the normal group,and 18 CIA mice that were successfully modelled were randomly di-vided into the model group,the plaster group(1.0 g/kg),and the fuselage group(0.12 g per time)ac-cording to the random number table method,6 mice in each group,and each administered group was given medication according to the body mass,and saline was given to both the normal and model groups.The normal group and the model group were given saline,and breathable adhesive paper was applied once a day for 4 h/session for 4 consec-utive weeks.The arthritis scoring index was used to observe the changes of arthritis symptoms and ar-thritis index scores of mice in each group.Micro-CT was used to observe the damage of hind paw of mice,real-time fluorescence PCR was used to de-tect the mRNA expression of IL-17,IL-1β and TNF-αin ankle joint tissues,and immunohistochemistry was used to detect the expression of OPG and RANKL proteins in ankle joint tissues,and hematox-ylin-eosin(HE)staining was used to observe the pathological changes of synovial tissues after the treatment.The pathological changes of synovial tis-sue were observed after hematoxylin-eosin(HE)staining,and the changes of osteoclasts in ankle joint tissue were observed by anti-tartaric acid phosphatase(TRAP)method.RESULTS:Compared with the normal group,the arthritis index score of the model mice was significantly higher(P＜0.05).Micro-CT showed severe bone erosion in the hind paws of the mice,destruction of the bone surface and reduction of bone volume.The expression of IL-17,IL-1β and TNF-α mRNA(PCR)in the ankle joint tissues was significantly higher(P＜0.05).Im-munohistochemistry showed that the relative ex-pression of OPG protein in the ankle joint tissues was reduced(P＜0.05).Immunohistochemistry showed a decrease in the relative expression of OPG protein(P＜0.01)and an increase in the rela-tive expression of RANKL protein(P＜0.01).HE re-sults showed moderate inflammatory cell infiltra-tion,swelling of synovial cells,massive formation of vascular opacities and synovial hyperplasia;an increase in the number of osteoclasts,roughness of the surface of articular cartilage tissue,severe bone destruction and thinning of the cartilage lay-er.Compared with the model group,the arthritic symptoms of mice in the cream group and the futa-lin group were relieved and the arthritis index score was reduced;the bone density of the mice's hind paws improved,effectively relieving osteopo-rosis;the expression of IL-17,IL-1β and TNF-αmRNA(PCR)in the ankle joint tissue was signifi-cantly reduced(P＜0.05);the immunohistochemical results showed that the relative expression of OPG protein was increased(P＜0.05),the relative expres-sion of RANKL protein decreased(P＜0.01).HE re-sults showed that synovial cell enlargement was significantly improved,mild inflammatory cell infil-tration,synovial hyperplasia was not obvious;the number of broken bone was reduced,articular car-tilage destruction was significantly improved and relieved,and the thickness of cartilage layer was significantly increased.CONCLUSION:Ancestral hemp poultice relieves local symptoms of RA,re-duces the expression of inflammatory factors and attenuates the inflammatory response,possibly by inhibiting osteoclast differentiation and activation through modulation of the OPG/RANKL signalling axis,which further ameliorates the biological ef-fects of articular bone and cartilage destruction.

mRNA([1.26±0.06]vs.[1.00±0.01]),and NR2B protein([1.47±0.05]vs.[1.00±0.01])was increased in the hypoxia group as compared to the control group(all P＜0.05),whereas the relative expression of NEAT1([1.02±0.10]vs.[1.00±0.03])were not statistically significant(P＞0.05),and the relative expression of MALAT1([1.12±0.13]vs.[1.00±0.08])and NEAT1([2.88±0.10]vs.[1.00±0.03])were increased in hypoxic preconditioned group.Compared with hypoxia group,the relative expression of NR2B mRNA([0.54±0.07]vs.[1.26±0.06])and NR2B protein([1.17±0.07]vs.[1.47±0.05])were decreased(both P＜0.05).(2)The differences in the relative expression of NR2B mRNA(F=36.92)and NR2B protein(F=56.98)after transfection of HT22 cells in the five groups were statistically significant(both P＜0.05).Compared with the negative control group,siMALAT1 group(NR2B mRNA:[2.04±0.08]vs.[0.94±0.04],NR2B protein:[1.72±0.13]vs.[0.93±0.02]),siNEAT1 group(NR2B mRNA:[2.15±0.13]vs.[0.94±0.04],NR2B

increased(all P＜0.05).(3)Differences in relative expression of haematopoietin breakdown product(145/150 kDa)protein(F=12.43),haematopoietin breakdown product(120 kDa)protein(F=7.15),and activated cysteamine protease protein 3 protein(F=6.61)were statistically significant in the 6 groups of HT22 cells transfected and treated with OGD/R(all P＜0.05).Compared with the siMALAT1 group,the siMALAT1+OGD/R group had 145/150kDa([1.42±0.48]vs.[0.85±0.34]),120 kDa([1.33±0.37]vs.[0.52±0.19])haematopoietin catabolism products and activated cysteamine protease protein

3([2.43±0.35]vs.[1.46±0.39])increased(all P＜0.05);compared with the siNEAT1 group,the siNEAT1+OGD/R group had a higher expression of 145/150 kDa([1.28±0.44]vs.[0.87±0.32]),120 kDa([0.81±0.36]vs.[0.63±0.16])relative expression of haematopoietic proteolytic products and activated cysteamine protease protein 3([1.51±0.45]vs.[1.01±0.27])increased(all P＜0.05).(4)The difference in HT22 cell survival rate among the 6 groups was statistically significant(F=5.54,P＜0.05).Compared with the negative control group,HT22 cell survival was decreased in the siMALAT1,siNEAT1,siMALAT1+OGD/R and siNEAT1+OGD/R groups([0.65±0.40],[0.76±0.35],[0.24±0.17],[0.23±0.16]vs.[0.84±0.04],all P＜0.05);cell viability was reduced in the siMALAT1+OGD/R group compared with the siMALAT1 group([0.24±0.17]vs.[0.65±0.40],P＜0.05);and cell viability was reduced in the siNEAT1+OGD/R group compared with the siNEAT1 group([0.23±0.16]vs.[0.76±0.35],P＜0.05).Conclusion HPC increased the expression of MALAT1 and NEAT1 in the hippocampus of mice,and MALAT1 and NEAT1 may participate in the neuroprotective effect of mice after ischemia and hypoxia by affecting the expression of NR2B.

Objective:To explore the anger emotional state,traits and expression characteristics in patients with schizophrenia with violent behavior in community.Methods:Twenty-five patients with schizopnrenia with a history of violent behavior among the community rehabilitation institutions were selected as the violent behavior group,and 74 patients with schizopnrenia without a history of violent behavior were selected as the nonviolent behavior group.The Brief Psychiatric Rating Scale(BPRS)was used to assess psychiatric symptoms,and the State-Trait An-ger Expression Inventory(STAXI)was used to assess anger characteristics.Results:Compared with the nonviolent behavior group,the violent behavior group had significantly higher scores in the trait of anger(patient dimension score,rational dimension score)and expression of anger(total score,restraint dimension score)[(28.0±23.8)vs.(19.6±13.3),(55.0±30.6)vs.(40.0±21.5),(34.2±11.6)vs.(27.3±10.7),(56.0±26.1)vs.(33.7±21.1),Ps＜0.05].Higher scores of rationality dimension of anger trait(OR=3.69,95％CI:1.43-7.98)and re-straint dimension of anger expression(OR=3.25,95％CI:1.39-7.47)were risk factors for violent behaviors.Conclusion:Compared with patients with schizopnrenia without violent behavior,patients with violent behavior history may show more lack of rationality,and poorer anger restraint.

Objective:To analyze the clinical characteristics, muscle imaging and pathological features of patients with anti-signal recognition particle positive immune-mediated necrotizing myopathy (SRP-IMNM).Methods:Nine patients with SRP-IMNM were collected in the Neuromuscular Disease Center of Jiaozuo People′s Hospital from May 2018 to May 2023, who were confirmed by skeletal muscle pathology and myositis-specific autoantibodies detection, and their clinical manifestations, muscle imaging and muscle pathology characteristics were systematically summarized.Results:Among the 9 patients with SRP-IMNM, there were 7 females and 2 males. The age of onset ranged from 18 to 59 years. All the patients presented proximal muscle weakness. Seven patients experienced neck weakness, and dysphagia was present in 5 patients. Laboratory examinations showed elevated serum creatine kinase levels in all 9 patients (1 866-6 725 U/L). Eight patients were combined with other antibodies positivity, except for anti-SRP antibody. Among them, 7 patients were combined with anti-Ro-52 antibody positivity, 4 patients combined with anti-Ro-52 antibody positivity alone, and 3 patients combined with 3 or more positive antibodies simultaneously. Those patients who presented with interstitial lung disease and cardiac involvement were all combined with other antibodies positivity. Seven patients completed thigh muscle magnetic resonance imaging (MRI), which showed diffuse skeletal muscle oedema, partial muscle atrophy and fatty replacement, primarily affecting the posterior thigh muscle group. Two patients underwent shank muscle MRI. The soleus involvement was evident, while the tibialis anterior muscle and gastrocnemius muscles were involved in 1 patient. All 9 patients showed varying degrees of scattered muscle fiber necrosis and regeneration on muscle biopsies. In 1 patient, a small amount of inflammatory cell infiltration was observed. Pipestem capillaries were observed in 4 patients. Immunohistochemical staining revealed a small number of CD68-positive lymphocytes in 8 patients. Additionally, 5 patients showed upregulation of major histocompatibility complex Ⅰ expression on the muscle fiber membrane, while 6 patients showed deposition of membrane attack complex (C5b-9) on non-necrotic muscle fibers and capillaries. P62 staining showed homogeneous fine-granular in sarcoplasm in 6 patients.Conclusions:In addition to proximal muscle weakness, patients with SRP-IMNM often experience neck weakness and dysphagia. Those with multiple antibodies are more likely to develop interstitial lung disease and cardiac involvement. SRP-IMNM patients have diffuse oedema in the affected muscles, and the posterior thigh muscles are more prone to atrophy and fatty tissue formation. C5b-9 deposition and pipestem capillaries are significant pathological features of SRP-IMNM, which provide additional evidence for clinical diagnosis.
