Objective To explore the function of electroacupuncture(EA)on body mass,fasting blood glucose,heat pain threshold,and transient receptor potential vanilloid 4(TRPV4)in the dorsal root ganglia(DRG)of rats with diabetic neuropathic pain(DNP).Methods A DNP rat model was formed by intraperitoneally injecting the animals with STZ.From days 15 to 21,bilateral Zusanli and Kunlun points of the DNP rat model were treated with electroacupuncture once daily for 30 min.We then measured their body mass,fasting blood glucose,and heat pain threshold.The co-expression of TRPV4 and NeuN in the rat L4～L6 DRG was detected by immunofluorescence.The effects of the TRPV4 agonist GSK1016790A on body mass,fasting blood glucose,and the heat pain threshold of DNP rats treated with electroacupuncture were detected.Results After the 7th day,body mass was significantly decreased(P<0.01)and fasting glucose was significantly increased(P<0.01)in the model group compared with the normal group.After the 21st day,compared with the model group,heat pain threshold of the model+electroacupuncture group was significantly higher(P<0.01);the results of co-expression of TRPV4 and NeuN immunofluorescence on rat L4～L6 DRG showed that:the expression of positive cells in the model group was significantly higher(P<0.01)than that in the normal group,the co-expression of TRPV4 and NeuN positive cells in L4～L6 DRG of rats in the model+electroacupuncture group was significantly lower(P<0.01)than that in the model group.The TRPV4 agonist GSK1016790A can reverse the downregulation of thermal pain threshold induced by electroacupuncture in DNP rats(P<0.01).Conclusion Electroacupuncture alleviated the DNP induced by STZ,and its mechanism may involve the inhibition of TRPV4 protein expression in the DRG.

ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）， network pharmacology and molecular docking techniques， to explore the pharmacodynamic material basis and mechanism of Renshen Wuweizi Tang in treating spleen-lung Qi deficiency syndrome. MethodsThe chemical components in the decoction of Renshen Wuweizi Tang were systematically characterized and identified by UPLC-Q-TOF-MS/MS， and network pharmacology was used to screen potential active ingredients， collect component targets and gene sets related to spleen-lung Qi deficiency syndrome， and obtain protein interaction relationships through STRING. Cytoscape 3.9.1 was used to construct a "formula-syndrome" association network and calculate topological feature values. Gene ontology（GO） function and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analysis were performed on core genes to explore potential pharmacodynamic links， the average shortest path between the formula-drug target network and the pharmacodynamic link gene network was calculated to discover dominant pharmacodynamic links， and MCODE plugin was used to identify core gene clusters from the dominant pharmacodynamic links， which were validated using Gene Expression Omnibus（GEO）， and molecular docking was performed between key components and core targets. ResultsOne hundred and thirty-seven components were identified in the negative ion mode， and eighty components were identified in the positive ion mode. After deduplication， a total of 185 components were identified， mainly composed of triterpenoid saponins（49） and flavonoids（54）. Based on the "formula-syndrome" correlation network analysis， energy metabolism was determined to be the dominant pharmacodynamic link of Renshen Wuweizi Tang in the treatment of spleen-lung Qi deficiency syndrome. The results of molecular docking showed that 7 components（adenosine， atractylenolide Ⅱ， atractylenolide Ⅲ， ginsenoside Rg₁， glycyrrhizin B₂， glycyrrhizin E₂ and campesterol） from 4 medicinal materials（Ginseng Radix et Rhizoma， Atractylodis Macrocephalae Rhizoma， Glycyrrhizae Radix et Rhizoma and Poria） in this formula might regulate energy metabolism by acting on 6 targets， namely cyclic adenosine monophosphate-response element binding protein 1（CREB1）， glyceraldehyde-3-phosphate dehydrogenase（GAPDH）， interleukin（IL）-6， nuclear transcription factor（NF）-κB1， peroxisome proliferator-activated receptor α（PPARα）， and tumor necrosis factor（TNF）， thus improving the symptoms of diseases related to spleen-lung Qi deficiency syndrome. ConclusionThis study established a UPLC-Q-TOF-MS/MS for rapid characterization and identification of chemical components in the decoction of Renshen Wuweizi Tang， expanding the understanding of the material composition of this formula， and found that 7 components might act on the key advantageous pharmacodynamic link "energy metabolism" through 6 targets to improve the related symptoms of spleen-lung Qi deficiency syndrome. This can provide a reference for the subsequent exploration of the material benchmark and mechanism of the famous classical formula.

OBJECTIVE: To explore the early changes in various liver function indicators in critically injured trauma patients assessed by intelligent calculation method, aiming to develop more advantageous diagnostic and treatment strategies for traumatic liver injury. METHODS: A retrospective study was conducted. Critically injured trauma patients [injury severity score (ISS) ≥ 16, age > 18 years old] admitted to the Emergency Medical Center of Tianjin Fifth Central Hospital from January 1, 2022, to December 1, 2023 were enrolled. ISS score and acute physiology and chronic health evaluation II (APACHE II) assessed by intelligent calculation method were collected upon patient admission to the emergency medical center. Trends in liver function indicators in fasting venous serum were analyzed at 6, 24 and 72 hours after admission, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), lactate dehydrogenase (LDH), albumin (ALB), total bilirubin (TBil), prothrombin time (PT). Patients were grouped based on APACHE II scores into those with APACHE II < 15 and APACHE II ≤ 15, and liver function indicators within 6 hours of admission were compared between the two groups. RESULTS: A total of 112 critically injured trauma patients were included, with 83 males and 29 females, an average age of (47.78±14.84) years old. The median ISS score was 21.0 (18.0, 26.0). The most common cause of injury for critically injured trauma patients was road traffic accidents (68 cases, accounting for 60.71%), followed by falls from heights, compression injuries, heavy object injuries, knife stabs, and explosion injuries. The most common injured areas was the limbs and pelvis (97 cases, accounting for 86.61%), followed by chest injuries, surface skin and soft tissue injuries, abdominal and pelvic organ injuries, head injuries, and facial injuries. The proportion of elevated LDH, AST, and ALT within 6 hours of admission was 77.68%, 79.46%, and 52.68%, respectively, while the proportion of decreased ALB was 75.89%, the abnormal rates of ALP, GGT, TBil, and PT were all below 50%. The ALT and AST levels of patients at 24 hours and 72 hours after admission were significantly lower than those at 6 hours after admission [ALT (U/L): 37.0 (22.0, 66.0), 31.0 (21.2, 52.0) vs. 41.0 (25.0, 71.0), AST (U/L): 55.5 (30.0, 93.5), 40.0 (27.0, 63.2) vs. 69.5 (39.0, 130.8), all P < 0.05]. There was no statistically significant difference in ISS score between APACHE II > 15 group (45 cases) and APACHE II ≤ 15 group [67 cases; 21.0 (18.5, 26.5) vs. 20.0 (17.0, 22.0), P > 0.05]. Nevertheless, compared with patients with APACHE II ≤ 15, patients with APACHE II > 15 have a higher abnormality rate of ALT and AST within 6 hours of admission [ALT abnormal rate: 66.44% (29/45) vs. 44.78% (30/67), AST abnormal rate: 93.33% (42/45) vs. 70.15% (47/67), both P < 0.05], and the levels of ALT and AST were higher [ALT (U/L): 56.0 (30.0, 121.0) vs. 35.0 (21.0, 69.0), AST (U/L): 87.0 (48.0, 233.0) vs. 52.0 (31.0, 117.0), both P < 0.05]. CONCLUSIONS Severe trauma patients frequently exhibit a high incidence of reversible early liver function impairment. Based on intelligent calculation method, the utilization of both the ISS and APACHE II scores demonstrates a distinct advantage in the assessment of their early liver injury.

Objective:To observe and analyze the subtype-specific prognostic factors for visual recovery in patients with demyelinating optic neuritis (DON) after glucocorticoid pulse therapy.Methods:A retrospective cohort study. A total of 195 patients (249 eyes) with DON diagnosed by ophthalmology examination at Department of Ophthalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2021 to December 2024 were included in the study. According to the results of serum antibody detection and clinical diagnostic criteria, the patients were divided into the neuromyelitis optica spectrum disorder (NMOSD)-associated optic neuritis (ON) (NMOSD-ON) group, the myelin oligodendrocyte glycoprotein antitide-associated ON (MOG-ON) group, and the double antibody negative ON group. They were 51 cases (58 eyes), 72 cases (103 eyes), and 72 cases (88 eyes) respectively. Baseline clinical data, imaging characteristics, and treatment protocols were collected. The primary endpoints were complete visual recovery [best-corrected visual acuity (BCVA) ≥ 1.0] and moderate recovery (BCVA ≥0.5) at 3 months post-onset. Multivariate logistic regression was used to identify independent prognostic factors for visual outcomes within each subtype.Results:At 3 months post-onset, complete recovery rates were 9 (15.5%, 9/58) in the NMOSD-ON group, 64 (62.1%, 64/103) in the MOG-ON group, and 31 (35.2%, 31/88) in the double-seronegative ON group. The results of multivariate regression analysis showed that age [odds ratio ( OR) =0.901, 95% confidence interval ( CI) 0.854-0.950, P<0.001] and peak visual acuity ( OR=0.311, 95% CI 0.147-0.660, P=0.002) and the involvement of optic nerve length ≥1/2 ( OR=3.849, 95% CI 1.083-13.682, P=0.037) were the influencing factors for the complete recovery of visual acuity in the affected eyes of the double antibody negative ON group. Age ( OR=0.958, 95% CI 0.933-0.983, P=0.001) was the only influencing factor for the complete recovery of visual acuity in the affected eyes of the MOG-ON group. Peak visual acuity ( OR=0.288, 95% CI 0.090-0.927, P=0.037) and optic nerve involvement length ≥1/2 ( OR=19.974, 95% CI 1.905-209.559, P=0.013) were the influencing factors for the complete recovery of visual acuity in the affected eyes of the NMOSD-ON group. Age ( OR=0.936, 95% CI 0.890-0.983, P=0.009), time from onset to intravenous infusion of methylprednisolone sodium succinate intervention ( OR=0.854, 95% CI 0.759-0.961, P=0.009), optic disc edema ( OR=4.405, 95% CI 1.108-17.512, P=0.035) and peak visual acuity ( OR=0.13, 95% CI 0.046-0.365, P<0.001) were the influencing factors for the moderate recovery of visual acuity in the affected eyes of the double antibody negative ON group. Peak visual acuity was the only influencing factor for the moderate recovery of visual acuity in the MOG-ON group ( OR=0.060, 95% CI 0.010-0.352, P=0.002) and the NMOSD-ON group ( OR=0.163, 95% CI 0.053-0.500, P=0.001). Conclusions:The prognostic factors for visual recovery in patients with DON after glucocorticoid pulse therapy are subtype-specific. Peak visual acuity is a common predictor for all subtypes. For NMOSD-ON and double antibody-negative ON, attention should be paid to the length of optic nerve lesions. MOG-ON is age-related. Early intravenous infusion of methylprednisolone sodium succinate for double antiantibody negative ON is more likely to achieve moderate vision recovery.

Purpose To establish a nomogram based on conventional ultrasound combined with contrast-enhanced ultrasound(CEUS)for predicting the probability of cervical central lymph node metastasis(CLNM)in clinical lymph node-negative(CN0)papillary thyroid carcinoma(PTC)patients.Materials and Methods A retrospective study was performed on 359 patients with single CN0 PTC,all of whom underwent thyroid surgery and prophylactic central compartment neck dissection in the First Affiliated Hospital of Shihezi University from September 2015 to March 2022.According to the postoperative pathological results,there were 116 cases with CLNM(+)and other 243 cases with CLNM(-).The indicators of gender,age,conventional ultrasound and CEUS were recorded,and multivariate stepwise Logistic regression was performed to screen out risk predictors to construct prediction models for CLNM in CN0 PTC.The receiver operating characteristic curves of prediction models were drawn,and the area under the curve(AUC)was further compared.The preferable prediction model was selected to establish the risk probability nomogram,and the prediction performance and clinical applicability of the nomogram model were assessed.Results Multivariate analysis showed that gender,age,the maximum diameter of nodule,capsule invasion and enhancement pattern on CEUS were risk factors for CLNM in CN0 PTC(all P<0.05).The AUC of prediction model 1 including the above five indicators was 0.753,and the AUC of prediction model 2 excluding CEUS indicator was 0.704.There were statistically significant difference in AUCs between the two models(Z=2.473,P=0.013).Prediction model 1 was selected to construct a risk probability nomogram for predicting CLNM in CN0 PTC.The nomogram had a C-index of 0.753 and showed well consistency on the calibration curve.Clinical decision curve analysis indicated that the nomogram could achieve ideal net benefit when the threshold probability was between 10.7%to 81.5%.Conclusion Gender,age,the maximum diameter of nodule,capsule invasion and enhancement pattern on CEUS may be the risk predictors for CLNM in CN0 PTC.The nomogram model based on the above indicators can predict the probability of CLNM effectively,and the CEUS indicators can substantially improve the prediction performance of the model.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.

Objective:To observe any effect of electroacupuncture (EA) on the expression of phosphorylated extracellular signal-regulated protein kinase (p-ERK1/2) and phosphorylated cyclic adenosine monophosphate response element binding protein (p-CREB) in the spinal dorsal horns of diabetics experiencing neuropathic pain.Methods:Eight rats were randomly selected from 30 healthy male Sprague-Dawley rats as the normal group (N), and the remaining twenty-two rats were treated with a single high-dose intraperitoneal injection of streptozotocin (STZ) to establish a neuropathic pain model. The rats modeled successfully were randomly divided into a model group (M, n=8) and an EA group ( n=8). In the EA group, electroacupuncture was applied at the bilateral Hou san li and Kunlun acupoints starting on the 15th day after the STZ injection. The daily sessions lasted 30 minutes for 1 week. Body weight (BW), fasting blood glucose (FBG) and paw withdrawal latency (PWL) were observed before the STZ injection and on the 7th, 14th, and 21st days afterward. The expression of p-ERK1/2 and p-CREB in the dorsal horns of the rats′ spinal cords was detected using western blotting. The count of p-CREB-positive cells in the dorsal horns and their co-localization with neurons was detected using immunofluorescence. Results:In comparison with the N group, the average BW of the M group on the 7th, 14th and 21st days after the STZ injection was significantly lower, while the average FBG was significantly higher. There was no significant difference between the M and N groups in the average PWL on the 7th day after the STZ injection, but it had decreased significantly in the M group on the 14th and 21st days. Compared with the M group, the average PWL of the EA group was significantly longer on the 21st day after the injection. The expression of p-ERK1/2 and p-CREB protein in the spines of the M group was significantly higher than in the N group. p-CREB positive cells were more numerous in the M group compared with the N group, while in the EA group they were fewer. P-CREB was co-located with neurons in the spinal dorsal horn.Conclusion:EA can alleviate neuropathic pain effectively, perhaps by inhibiting the expression of p-ERK1/2 and p-CREB in the dorsal horns of the spinal cord.
