ObjectiveTo observe the clinical efficacy and safety of hot ironing with Haitongpi Formula （海桐皮方， HF） in the treatment of lumbar disc herniation （LDH） of cold-dampness obstruction type. MethodsA total of 70 patients with cold-dampness obstruction type LDH were randomly divided into a treatment group and a control group， with 35 cases in each group. Both groups received three movements technique of Qinggong Spinal Manipulation （QSM） as the basis for treatment. In addition， the treatment group received hot ironing with HF， while the control group applied Diclofenac Sodium Gel externally. The treatment duration for both groups was 14 days. The clinical efficacy was compared between groups. Japanese Orthopedic Association （JOA） score， visual analog scale （VAS） for pain， pain pressure threshold （PPT） for lumbar positive response points， and traditional Chinese medicine （TCM） symptom scores were compared， on day 7， and day 14 of treatment， as well as on day 7 and day 14 of follow-up. The lumbar curvature index （LCI） was also compared before treatment and on day 14 of treatment. Adverse reactions during the study were recorded for both groups. ResultsA total of 35 patients in the treatment group and 34 patients in the control group were included for final analysis. The clinical total effective rate of the treatment group （91.43%， 32/35） was significantly higher than that of the control group （82.35%， 28/34， P＜0.05）. Both the JOA score and PPT of the two groups increased on day 7 and day 14 of treatment， and on day 7 and day 14 of follow-up. VAS scores and TCM symptom scores both decreased. The LCI of both groups increased on day 14 of treatment （P＜0.01）. Compared with the control group at the same time points， on day 14 of treatment and day 7 and day 14 of follow-up， the treatment group had higher JOA scores and PPT， and lower VAS scores and TCM symptom scores. The LCI of the treatment group increased on day 14 of treatment （P＜0.05 or P＜0.01）. One case in the control group showed mild skin allergy， with no other adverse reactions observed in either group. ConclusionBased on three movements technique of QSM， hot ironing with HF shows better clinical efficacy than external Diclofenac Sodium Gel in the treatment of cold-dampness obstruction type LDH. It can significantly reduce lumbar pain， increase pain pressure threshold， improve clinical symptoms， lumbar function， and lumbar curvature， with good safety.

The primary intravenous anesthetics employed in clinical practice encompass dexmedetomidine (Dex), propofol, ketamine, etomidate, midazolam, and remimazolam. Apart from their established sedative, analgesic, and anxiolytic properties, an increasing body of research has uncovered neuroprotective effects of intravenous anesthetics in various animal and cellular models, as well as in clinical studies. However, there also exists conflicting evidence pointing to the potential neurotoxic effects of these intravenous anesthetics. The role of intravenous anesthetics for neuro on both sides of protection or toxicity has been rarely summarized. Considering the mentioned above, this work aims to offer a comprehensive understanding of the underlying mechanisms involved both in the central nerve system (CNS) and the peripheral nerve system (PNS) and provide valuable insights into the potential safety and risk associated with the clinical use of intravenous anesthetics.

This study employed Mendelian randomization (MR) analysis to confirm the association between breast cancer and the risk of anxiety and depression, and to explore the molecular mechanisms by which lipid nanoparticles of ketamine (LNP@Ket) modulate these behaviors in a mouse model of breast cancer. Through single-cell transcriptomic analysis, the study aimed to clarify nuclear factor erythroid 2-related factor 2 (Nrf2)'s role in the development of anxiety and depression in these mice. Analysis of patient data from genome-wide association study (GWAS) databases supported the link between breast cancer, anxiety, and depression. In vivo experiments demonstrated that treating breast cancer mice with LNP@Ket significantly reduced anxiety and depression behaviors. The synthesis of LNP@Ket and its subsequent analysis highlighted its inhibitory effects on these behaviors. Single-cell transcriptomic sequencing identified key cells and genes affected by LNP@Ket treatment, particularly emphasizing Nrf2. Upregulation of Nrf2 in astrocytes increased the expression of antioxidant enzymes and reduced pro-inflammatory cytokines, alleviating anxiety and depression symptoms by inhibiting neuroinflammation and neurodegeneration. This comprehensive study highlights the pivotal role of Nrf2 in the therapeutic efficacy of LNP@Ket for treating anxiety and depression in breast cancer mice.

OBJECTIVES: The objective of this study is to measuring the morphology and position of bilateral temporomandibular joints in patients with unilateral and bilateral molar scissor bite and simulating the deformation of the mandible during occlusion, in order to provide thesis for the diagnosis of temporomandibular joint disease in patients with unilateral and bilateral molar scissor bite. METHODS: This study was a retrospective study. A total of 10 patients with unilateral molar scissor bite (the unilateral molar scissor bite group) and 10 patients with bilateral molar scissor bite (the bilateral molar scissor bite group) were selected as the experimental group, and 20 adult patients with classⅠ of angle classification of similar ages were selected as the control group. All patients underwent cone beam computed tomography scans, by measuring the width of the fossa, height of the fossa, articular eminence inclination, long axis of the condyle, minor axis of the condyle, horizontal angle of the condyle and the space of the temporomandibular joint, compare temporomandibular joint morphology and position. The three-dimensional finite element analysis of the mandible morphology was carried out to evaluate the force and deformation of the mandible by using software to simulate the occlusion of the patients. It was further explored the relationship between the force of the mandible morphology and the possible temporomandibular joint disorder symptoms of the patients. RESULTS: Intergroup comparisons for the unilateral molar scissor bite group and left sides of the other groups revealed that the superior articular space in the group with unilateral molar scissor bite was shorter than that in the control group (P<0.05); the long axis of the condyle in the unilateral and bilateral molar scissor bite group were both shorter than that of the control group (P<0.05); among which the unilateral group was larger than the bilateral group, and the minor axis of the condyle in bilateral molar scissor bite group was smaller than in the control group (P<0.05), and the unilateral and bilateral condylar groups were larger than the control group (P<0.05); and the condylar horizontal angle in the unilateral and bilateral groups were larger than that in the control group (P<0.05). The normal sides of the unilateral molar scissor bite group and right sides of the other groups had smaller superior articular space than the control group (P<0.05); and the condylar long-axis in bilateral group was smaller than the control group (P<0.05); and the normal side of the condylar short-axis unilateral group was larger than that of the bilateral condylar group. Three-dimensional finite element analysis: the condyle of patients with molar scissor bite was a concentrated area of deformation during the bite of the mandible, when the first molar occlusion of the scissors bite side was simulated, the maximum deformation was located in the condyle in the X-axis and Z-axis directions. The amount of deformation was greater than that of the scissor bite side in the X-axis direction, while in the Z-axis direction, the normal side was greater than the scissor bite side. The maximum sites of local deformation in the X-axis direction were located in anterior and posterior the transverse crest of scissor bite side, and the minimum sites of local deformation was at 1/3 of the anterior slope of the inner pole of the normal side, the maximum local deformation sites in the Z-axis direction were located in the outer pole and below the outer pole of the normal side. The X-axis deformation value was the largest in the molars occlusion on the normal side, the Y-axis deformation value was in the premolars occlusion on the normal side, and the Z-axis deformation value was the largest in the centric occlusion, the deformation value of the condyle was not most significant in molar scissor bite. CONCLUSIONS Unilateral and bilateral molar scissor bite resulting in a short condyle morphology, and the bilateral group had a shorter condylar morphology than the unilateral group. The condyle of the patient with molar scissor bite is a concentrated area of poor occlusal deformation, and the largest sites of deformation are distributed near the transverse ridge of the inner and outer poles of the condyle. Different occlusion conditions have an effect on condylar deformation values, but do not indicate whether there is a clear association between them.

Objective To investigate the gray matter volume(GMV)changes and molecular basis underlying antipsychotic-induced weight gain(AIWG).Methods One hundred twenty-nine first-episode schizophrenia patients from October 2019 to December 2021 were enrolled in this study.Patients with≥7%weight gain(weight gain,WG)and patients with<3%weight changes(weight stable,WS)were studied.All patients underwent T1-weighted MRI scanning at baseline and after 8 week treatment.Transcriptome-neuroimaging correlations were used to investigate brain gene profiles from the Allen Human Brain Atlas and GMV changes induced by AIWG.Results Thirty-three patients with WG and 27 with WS completed the GMV measures.Compared with baseline,the WG group showed reduced GMV in right hippocampus,left basal ganglia,and right inferior parietal lobule,etc.and increased GMV in bilateral thalamus(P<0.05).The WS group showed reduced GMV in bilateral orbital gyrus,bilateral inferior frontal gyrus and bilateral hippocampus(P<0.05).These GMV changes in WG group were spatially correlated with expression levels of 354 genes,which were exclusively enriched in Cushing syndrome,neuroinflammation and glutamatergic signaling,and Pnoc+.Conclusion The study has demonstrated increased GMV in thalamus in schizophrenia patients with AIWG which may be associated with Cushing syndrome and Pnoc+.These findings may provide important insights into the molecular mechanisms of AIWG.

Objective:To investigate clinical curative effect of multiple composite tissues replantation with microsurgical technique in single hand.Methods:From May 2008 to December 2021, the clinical data of patients who underwent multiple composite tissue replantation in single hand in Chongming Hospital Affiliated to Shanghai University of Medicine & Health Sciences and Taizhou Hospital of Zhejiang Province, Wenzhou Medical University, were retrospectively analyzed. According to the severed site, anatomical level, the injury cause, the severity of injury, the size of severed tissue, and replantation conditions (such as blood vessels for anastomosis), the severed tissue was evaluated and carried out modified classification (type Ⅰ-Ⅳ) before the operation, and the surgical plan was designed. The severed composite tissue was debrided in emergency, the severed bone and muscle tissue were fixed, and the arteries, veins and nerves were anastomosed by microsurgical technique under a high-power microscope. The ratio of arteries to veins was 1∶1-1∶2. If enough arteries and veins could not be found, arteriovenous shunt could be used to form arterial venous flap or venous arterialized flap, or form artery flap by just artery anastomosis, or form venous flap by just vein anastomosis. Then skin tissue was sutured after recanalization. After the operation, the patients received specialized treatment and guided rehabilitation exercise. The wound healing of hand, skin color, skin quality, swelling degree, sensation, pain degree of joint, and activity function were followed up after the operation. At the last follow-up, the patient’s self-evaluation of the treatment effect was divided into three levels: satisfactory, average, and unsatisfactory. One chief physician and one doctor-in-charge were responsible for the comprehensive evaluation of curative effect, according to the assessment standard for upper limb function issued by Chinese Medical Association of Hand Surgery. 80-100 points were excellent, 60-79 points were good, 40-59 points were fair, and <40 points were poor.Results:A total of 94 severed composite tissues in 35 patients, including of 20 male patients and 15 female patients were enrolled. The average age was 36.4 years (range, 16-65 years). Fifty severed tissues in 18 cases were classified into type Ⅰ, 40 severed tissues in 15 cases type Ⅱ, 4 severed tissues in 2 cases type Ⅲ. Among the 35 cases, 1 case of thumb pulp severed tissue was necrotic at the edge (0.3 cm×0.5 cm) due to local contusion, 1 case of index finger lateral severed tissue was necrotic at the edge (0.3 cm×0.8 cm) due to local avulsion injury, and healed after dressing change, and the other replanted composite tissue survived. The patients were followed up for 3 to 65 months (average, 18.5 months). The wounds were completely healed, and the color, elasticity, and quality of the replanted tissue was close to the surrounding normal skin. There was no obvious swelling or atrophy deformity of the hands. According to the patients’ self-assessment, 31 cases were satisfied and 4 cases were average. Comprehensive evaluation of hand function and appearance: excellent in 23 cases, good in 9 cases, fair in 3 cases, excellent and good rate was about 91.4% (32/35).Conclusion:Though multiple composite tissues replantation with microsurgical technique in single hand is difficult, and vascular anastomosis technical requirement is high, once surgery succeeds, the function and appearance can get good recovery, and patient satisfaction is also relatively high.

Objective To investigate the causal relationship between walking pace(WP)with interver-tebral disc degeneration(IVDD)and low back pain(LBP)by using two-sample Mendelian randomisation(MR)analysis method.Methods A genome-wide association study database of WP,IVDD and LBP was ob-tained,and single nucleotide polymorphisms(SNP)strongly associated with exposure were obtained as the in-strumental variables.The two confounders of smoking and sedentary were conservatively removed,and the MR analyses were performed by inverse variance weighting(IVW),weighted median,and MR-Egger methods to assess the causal relationship between WP with IVDD and LBP.The consistency and accuracy of results were ensured by heterogeneity,diversity tests,MR-PRESSO and negative control.Results The I VW results showed a significant negative correlation between WP and IVDD(OR=0.348,95％CI:0.183-0.661,P=0.001)and vice versa(OR=0.972,95％CI:0.953-0.992,P=0.007).Meanwhile there was also a significant negative correlation between WP and LBP(OR=0.214,95％CI:0.119-0.385,P＜0.001),but no causal re-lationship was found between LBP and WP.Conclusion Faster WP could effectively prevent the occurrence of IVDD and LBP,and IVDD may contribute to the occurrence of slow walking.

OBJECTIVE To investigate the related factors of central lymph node metastasis(CLNM)in papillary thyroid carcinoma(PTC)with capsular invasion,and to construct a clinical nomogram prediction model.Its purpose is to provide theoretical basis for clinical diagnosis and treatment.METHODS The clinical data of PTC patients with capsule invasion admitted to the Department of General Surgery,Baoding First Central Hospital from October,2020 to October,2023 were retrospectively analyzed.The data included gender,age,body mass index(BMI),aspect ratio,tumor location,multifocality,microcalcification,Hashimoto thyroiditis(HT)and tumor diameter.According to the presence or absence of CLNM,the patients were divided into the normal group(107 cases)and the metastasis group(108 cases).Univariate and multivariate analysis of the data were performed to construct a visual nomogram prediction model,and the receiver operating characteristic(ROC)curve was drawn to evaluate the diagnostic efficacy of the model.The nomogram model was internally verified using a Bootstrap test with 1000 repeated samples.Consistency index(C-index)and calibration curve were used to describe the prediction performance and prediction accuracy of the model.Finally,the clinical decision curve(DCA)was drawn to determine the clinical application ability of the model.RESULTS A total of 215 PTC patients with capsular invasion were included,of whom 108(50.23%)had CLNM.Univariate analysis showed that the occurrence of CLNM was associated with tumor diameter,aspect ratio>1,tumor located in the lower pole,multifocality,and HT(P<0.05).Multivariate regression analysis showed that tumor diameter,aspect ratio>1,tumor located in the lower pole and multifocus were independent risk factors for CLNM(OR=1.401,1.875,2.291,2.303,P<0.05),and HT was a protective factor for CLNM(OR=0.501,P<0.05).Based on the above risk factors,a nomogram prediction model for CLNM in patients with PTC with capsule invasion was constructed.The ROC curves showed that the area under the curve(AUC)was 0.859(95%CI:0.792-0.925,Yoden Index was 0.734,the sensitivity was 0.878,a specificity was 0.856),and the model had higher predictive value.Internal validation consistency index(C-index)was 0.83(95%CI,0.748 to 0.959).The calibration curve showed that the predictive value was close to the ideal curve,and it had good consistency.The DCA curve showed that the model had good clinical efficacy.CONCLUSION Larger tumor size,aspect ratio>1,tumor located in the lower pole and multifocality suggest higher risk of CLNM in PTC with capsular invasion,while HT is a protective factor for CLNM.The nomogram model based on the above risk factors has high discrimination and calibration,which is helpful for clinicians in preoperative evaluation and intraoperative exploration,so that high-risk patients can be prevented and treated as soon as possible.
