Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

OBJECTIVE: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest. METHODS: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.0)years old. The duration of the disease ranged from 8 to 21 days. According to the different surgical methods, the patients were divided into control group and study group, with 50 patients in each group. The control group consisted of 23 males and 27 females, with an average age of (38.35±18.05) years old, who underwent rib preservation periosteal internal fixation. In the study group, there were 31 males and 19 females, with an average age of (38.15±17.99) years old, treated with thoracoscopic nickel-titanium shape memory alloy circumferential bone plate. The pulmonary function indices, electrocardiographic monitoring indices, pain severity, levels of inflammatory factors, complications, rehabilitation indices, and therapeutic efficacy were compared between the two groups before and after treatment. RESULTS: All patients were followed up for 6 months. After 3 days of treatment, the heart rate of both groups was (102.43±13.74) beats per minute vs (86.26±8.06) beats per minute, respiratory rate (28.45±3.40) breaths per minute vs (22.05±2.85) breaths per minute, blood oxygen saturation (89.68±3.66)% vs (98.46±4.84)%, rest pain (3.5±0.5) points vs (2.6±0.6) points, movement pain (3.6±0.5) points vs (2.5±0.5) points, and these differences were statistically significant(P<0.05). The levels of Interleukin-6 (IL-6) (102.30±17.00) pg·ml^-1 vs (85.68±21.20) pg·ml^-1 and tumor necrosis factor-alpha (TNF-α)(33.44±4.85) pg·ml^-1 vs (18.14±4.28) pg·ml^-1 in both groups exhibited an increase post-treatment, while the C-reactive protein (CRP) (75.51±10.54) mg·L^-1 vs (60.75±9.84) mg·L^-1 demonstrated a decrease compared to pre-treatment levels. Furthermore, the study group displayed significantly lower levels than the control group (P<0.05). After 10 days of treatment, the peak expiratory flow rate (3.31±0.52) L·s^-1 vs (5.69±0.74) L·s^-1, forced expiratory volume (1.46±0.29) L vs (2.06±0.38) L, and forced vital capacity (2.68±0.95) L vs (4.26±1.05) L of both groups exhibited significant improvements compared to pre-treatment levels. Moreover, the study group demonstrated significantly higher values than the control group (P<0.05). The incidence of postoperative complications in the study group was significantly lower compared to the control group (6 cases vs 14 cases, P<0.05). Additionally, the duration of bone callus formation(9.50±1.40) days and fracture healing (72.20±8.32) days in the study group was significantly shorter compared to the control group(11.35±2.15) days, (93.70±9.90) days (P<0.001). CONCLUSION Compared with traditional rib-preserving internal fixation, patients with MRF and flail chest treated with minimally invasive internal fixation with thoracoscopic nickel-titanium shape memory alloy surround bone plate have better therapeutic effect, because of less surgical trauma, less pain and inflammatory reaction, fewer postoperative pulmonary complications, faster and better recovery of lung function, and thus promote the recovery of patients.

Surgical methods for varicocele remain controversial. This study intends to evaluate the efficacy and safety of different surgical approaches for treating varicocele through a network meta-analysis (NMA). PubMed, Embase, Cochrane, and Web of Science databases were thoroughly searched. In total, 13 randomized controlled trials (RCTs) and 24 cohort studies were included, covering 9 different surgical methods. Pairwise meta-analysis and NMA were performed by means of random-effects models, and interventions were ranked based on the surface under the cumulative ranking curve (SUCRA). According to the SUCRA, microsurgical subinguinal varicocelectomy (MSV; 91.6%), microsurgical retroperitoneal varicocelectomy (MRV; 78.2%), and microsurgical inguinal varicocelectomy (MIV; 76.7%) demonstrated the highest effectiveness in reducing postoperative recurrence rates. In this study, sclerotherapy embolization (SE; 87.2%), MSV (77.9%), and MIV (67.7%) showed the best results in lowering the risk of hydrocele occurrence. MIV (82.9%), MSV (75.9%), and coil embolization (CE; 58.7%) were notably effective in increasing sperm motility. Moreover, CE (76.7%), subinguinal approach varicocelectomy (SV; 69.2%), and SE (55.7%) were the most effective in increasing sperm count. SE (82.5%), transabdominal laparoscopic varicocelectomy (TLV; 76.5%), and MRV (52.7%) were superior in shortening the length of hospital stay. The incidence rates of adverse events for MRV (0), SE (3.3%), and MIV (4.1%) were notably low. Cluster analyses indicated that MSV was the most effective in the treatment of varicocele. Based on the existing evidence, MSV may represent the optimal choice for varicocele surgery. However, selecting clinical surgical strategies requires consideration of various factors, including patient needs, surgeon experience, and the learning curve.

Patients suffering from nerve injury often experience exacerbated pain responses and complain of memory deficits. The dorsal hippocampus (dHPC), a well-defined region responsible for learning and memory, displays maladaptive plasticity upon injury, which is assumed to underlie pain hypersensitivity and cognitive deficits. However, much attention has thus far been paid to intracellular mechanisms of plasticity rather than extracellular alterations that might trigger and facilitate intracellular changes. Emerging evidence has shown that nerve injury alters the microarchitecture of the extracellular matrix (ECM) and decreases ECM rigidity in the dHPC. Despite this, it remains elusive which element of the ECM in the dHPC is affected and how it contributes to neuropathic pain and comorbid cognitive deficits. Laminin, a key element of the ECM, consists of α-, β-, and γ-chains and has been implicated in several pathophysiological processes. Here, we showed that peripheral nerve injury downregulates laminin β1 (LAMB1) in the dHPC. Silencing of hippocampal LAMB1 exacerbates pain sensitivity and induces cognitive dysfunction. Further mechanistic analysis revealed that loss of hippocampal LAMB1 causes dysregulated Src/NR2A signaling cascades via interaction with integrin β1, leading to decreased Ca²⁺ levels in pyramidal neurons, which in turn orchestrates structural and functional plasticity and eventually results in exaggerated pain responses and cognitive deficits. In this study, we shed new light on the functional capability of hippocampal ECM LAMB1 in the modulation of neuropathic pain and comorbid cognitive deficits, and reveal a mechanism that conveys extracellular alterations to intracellular plasticity. Moreover, we identified hippocampal LAMB1/integrin β1 signaling as a potential therapeutic target for the treatment of neuropathic pain and related memory loss.

Objective:To investigate the changes of thyroid hormones and the flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyrotoxicosis before and after treatment with methimazole.Methods:A case-control study was conducted to select 45 cases of Graves' disease and 45 cases of Hashimoto's thyroiditis from October 2021 to December 2022 in the Department of Endocrinology, North China University of Science and Technology Affiliated Hospital. The changes of thyroid hormone and blood flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyroiditis before and after treatment with methimazole were analyzed. Measurement data satisfying normal distribution were expressed by xˉ±s, and the mean between two groups was compared by t test. Measurement data not satisfying normal distribution were expressed by M( Q1, Q3), and the median between two groups was compared by Wilcoxon rank sum test. χ 2 test was used to compare the constituent ratio of enumeration data among groups. Results:There was no significant difference in thyroid stimulating hormone (TSH) between the two groups before treatment, and there was no significant difference in TSH between the two groups after 1 month and 3 months of treatment (all P>0.05). The levels of free triiodothyronine (FT3) were (24.09±9.29) pmol/L and (17.41±9.36) pmol/L in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. FT4 were (60.23±20.82) and (43.47±21.71) pmol/L, respectively, and the peak stolie vloiy (PSV) were (69.53±5.70) and (52.65±4.64) cm/s, respectively in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. There were significant differences between the two groups ( t values wrere 3.39 and 3.74, Z=13.83, all P<0.001). The difference of FT3 between one month after treatment and before treatment was (-6.36±5.32) and (-12.64±9.08) pmol/L ( t=4.02, P<0.001) and the difference in FT3 between 3 months of treatment and before treatment was (-10.14±9.50) and (-17.80±11.17) pmol/L, respectively ( t=3.51, P<0.001) between the Graves disease group and the Hashimoto's thyroiditis group. The difference in FT4 between the Graves disease group and the Hashimoto's thyroiditis group after 1 month of treatment and before treatment was (-28.47±10.09) and (-20.57±14.48) pmol/L ( t=7.01, P<0.001), and the difference of FT4 was (-47.06±20.57) and (-30.17±20.54) pmol/L ( t=3.91, P<0.001) between the Graves disease group and the Hashimoto toxin group. The difference between one month after treatment and before treatment was (-13.10(-34.10,-2.60)) and (-10.50(-27.5,-0.20)) cm/s ( Z=2.63, P=0.009), respectively. The difference between 3 months and before treatment was (-31.40(-53.20,-12.70)) and (-19.90(-46.00,-4.70)cm/s ( Z=4.40, P<0.001)) between the Graves disease group and the Hashimoto's thyroiditis group, and the difference was statistically significant. Conclusion:Thyroid hormone levels were decreased after treatment with methimazole in patients with diffuse toxic goiter and Hashimoto toxemia, but the difference was not statistically significant. The PSV level of superior thyroid artery in patients with diffuse toxic goiter was significantly lower than that in patients with Hashimoto's thyrotoxicosis.

BACKGROUND:At present,there is still controversy in clinical practice about the choice of internal fixation of Pauwels type Ⅲ femoral neck fracture,and the selection of internal fixation that provides stable fixation strength is the key basis for achieving Pauwels type Ⅲ fracture fixation. OBJECTIVE:The three-dimensional finite element analysis method was used to test the difference in biomechanical strength of three types of internal fixation in Pauwels type Ⅲ femoral neck fracture,which provided a reference for its clinical treatment. METHODS:Using the CT data of the left femur of a healthy male volunteer,a complete femur and its cancellous bone were reconstructed in Mimics software,and Geomagic studio software was used for reverse modeling.Cannulated compression screw,dynamic hip screw,and femoral neck system were created in UG-NX software.Three kinds of internal fixation models were assembled on the femur model,and Pauwels type Ⅲ femoral neck fracture was simulated by Hypermesh software.Finally,Abaqus software was used to carry out finite element experimental analysis to analyze and compare the stress distribution,stress peak,strain,and displacement distribution caused by fixed femoral neck fracture of different internal fixation systems. RESULTS AND CONCLUSION:(1)The stress of the proximal femur bone mass was mainly distributed in the area below the femoral neck near the fracture end,with the highest stress peak in the dynamic hip screw group and the smallest in the femoral neck system group.(2)The stress distribution of the internal fixation device was mainly concentrated on the screw surface near the fracture line,with the highest stress peak in the femoral neck system group and the smallest in the dynamic hip screw group.(3)The main strain field of the proximal femur bone mass was distributed in the upper surface area where the bone and screw contacted,and the yield strain was the smallest in the femoral neck system group and the largest in the cannulated compression screw group.(4)The main strain field of the internal fixation device model was distributed on the upper surface of the femoral neck screw,with the yield strain being the smallest in the femoral neck system group and the largest in the cannulated compression screw group.(5)The displacement distribution values of femur,proximal bone mass,distal bone block,internal fixation device and internal fixation with the femur as a whole in the three femoral neck fracture internal fixation models decreased gradually from proximal to distal,and the peak displacement of the femoral neck system group was the largest and the lowest in the dynamic hip screw group.(6)The results showed that when the Pauwels type Ⅲ femoral neck fracture was fixed,the stress distribution of femoral neck system was more uniform,the mechanical conduction characteristics were better,and it was subjected to lower yield strain,higher stress and higher displacement.It has relatively better biomechanical stability and can provide a superior mechanical environment for fracture healing.

Objective To explore accuracy and clinical effect of robot-assisted implantation of sacroiliac penetrating screw in orthopedic surgery for posterior pelvic ring fracture.Methods The clinical data of 24 patients with posterior pelvic ring frac-ture treated with robot-assisted sacroiliac penetration screws from August 2022 to August 2023 were retrospectively analyzed,including 10 males and 14 females;aged from 21 to 73 years old with an average of(49.29±14.48)years old;according to Tile pelvic fractures,13 patients were type B and 11 were type C.The effect of screw placement was evaluated according to Gras criteria based on postoperative CT scan results.At the final follow-up,fracture healing was evaluated according to Matta score,and functional recovery was evaluated by Majeed score.Results All patients were followed up for 3 to 13 months with an aver-age of(6.00±3.28)months.Totally 36 sacroiliac penetrating screws,18 S1 penetrating screws,18 S2 penetrating screws were inserted,a total of 29 were excellent and 7 good according to Gras standard.Screw adjustment times was 0.00(0.00,0.75)times.At the final follow-up,Matta score was excellent in 18 patients,5 good and 1 moderate,and the maximum displacement distance was 2.55(0.00,5.65)mm.Majeed score was 84.37±8.38,15 patients were excellent,7 good and 2 moderate.Con-clusion Robot could accurately and safely assist in the placement of sacroiliac joint screws for the treatment of posterior pelvic ring fractures,and promote postoperative functional recovery of patients.

This study analyzed and compared the epidemiological characteristics of foodborne listeriosis in the United States and China,to provide evidence for optimizing the listeriosis surveillance program in China.Descriptive statistical analysis was performed on the listeriosis monitoring data from 2009 to 2021 registered in the FDOSS system and the attribution estimates of Listeria monocytogenes(L.monocytogenes)from 2013 to 2021 published by IFSAC.Sporadic and outbreak data on listeriosis in China from the CNKI,Wanfang Medical,and CQVIP databases were collected.From 2009 to 2021,a total of 1 037 listeriosis cases were reported in the United States,including 902 hospitalizations and 165 deaths.The peak of cases caused by Lm con-taminated food was in July.The number of cases,hospitalizations,and deaths accounted for 18.4％(191/1 037),20.5％(185/902),and 22.4％(37/165)of the total,respectively.Most listeriosis outbreaks were attributed to three food groups:dairy products,vegetable crops,and fruits,with attribution percentages ranging from 73.8％to 89.6％.The overall incidence of list-eriosis in China was not high:619 cases were reported from 2009 to 2021,and only 177 cases were recorded in detailed inci-dence years;the maximum number of cases in 2018 was 26.A total of 220 cases were reported with detailed onset months;the highest number of cases in April was 30.Data on listeriosis cases in China are incomplete and sporadic,and only seven cases have been successfully traced to food.Listeriosis surveillance systems in the United States are relatively complete,and there are more foodborne outbreaks.Dairy products,vegetable row crops,and fruits are the most likely causes of disease outbreaks.Although only sporadic cases have been reported in China,China should take actions such as gradually improving multi-department coop-eration mechanisms,achieving data sharing and deepening data mining,and accelerating progress in the detection technology of food-borne pathogenic microorganisms,to ensure food safety and public health.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.
