ObjectiveTo investigate the effects of Chaihu and Longgu Mulitang （CLMT） on hippocampal neural damage in the mouse model of depression via the extracellular signal-regulated protein kinase （ERK）/cAMP-response element-binding protein （CREB） signaling pathway. MethodsSeventy-eight male C57BL/6 mice were randomly allocated into normal control， model， low/medium/high-dose （2.89， 5.78， and 11.56 g·kg^-1， respectively） CLMT， and paroxetine （10 mg·kg^-1） groups. A depression model was established by chronic unpredictable mild stress （CUMS） combined with social isolation. Behavioral tests were carried out to evaluate depressive-like behaviors. Hematoxylin-eosin staining and Nissl staining were performed to assess hippocampal morphology and neuronal damage. Immunofluorescence was employed to detect glial fibrillary acidic protein （GFAP） and ionized calcium-binding adapter molecule 1 （Iba1）. Real-time PCR was employed to measure the mRNA levels of ERK and CREB. Western blot was employed to determine the expression of ERK/CREB pathway proteins and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. Molecular Operating Environment （MOE） software was used for molecular docking to evaluate the interactions between CLMT components and target proteins. ResultsCompared with the normal control group， the model group showed decreased sucrose preference （P0.01）， increased tail-suspension immobility time （P0.01）， decreased activity in the central region of the open field test （P0.01）， and decreased activity in the middle and open-arm region of the elevated plus maze test （P0.01）. The hippocampal area in the model group showed wrinkled cells and a reduction in the number of cells， neurons with reduced sizes and Nissl bodies， enhanced fluorescence intensity of GFAP and Iba1 （P0.01）， and down-regulated expression of phosphorylated （p）-ERK， p-CREB， and BDNF （P0.05， P0.01） and mRNA levels of ERK and CREB （P0.01）. Compared with the model group， the CLMT group showed increased body weight （P0.05， P0.01）， restored cell morphology， with only a small number of ruptured cells， normal neuronal structure and morphology with obvious nuclei and abundant Nissl bodies， weakened fluorescence intensity of GFAP and Iba1 （P0.05， P0.01）， up-regulated mRNA levels of ERK and CREB （P0.05， P0.01） and protein levels of phosphorylated （p）-ERK， p-CREB， and BDNF in the hippocampal tissue （P0.05， P0.01）. The results of molecular docking indicated that nine active ingredients in CLMT had good binding affinity with ERK and CREB. ConclusionCLMT may ameliorate the hippocampal nerve injury in the mouse model of depression by regulating the ERK/CREB pathway.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.

Objective To analyze the factors influencing the occurrence of post-embolization syndrome(PES)after transhepatic arterial chemoembolization(TACE).Methods A total of 107 patients with hepatocellular carcinoma(HCC),who received TACE treatment at authors'hospital between February 2021 and March 2023,were included in the study.Among them,56 patients developed PES(PES group)and 51 patients did not develop PES(non-PES group).The demographic data,medical history,pathological findings,laboratory indicators and operation-related materials were compared between the two groups,and the risk factors for PES were analyzed.Results There were statistically significant differences in tumor diameter,albumin(ALB)level,preoperative physical condition(ECOG)score,type of embolization agent,drug-loaded microspheres,number of microspheres,and dosage of loaded drug between the two groups(all P＜0.05).Multivariate Logistic analysis revealed that drug-loaded microspheres,number of microspheres,and dosage of loaded drug were the independent risk factors for PES occurring after TACE(all P＜0.05).Conclusion HCC patients treated with TACE using drug-loaded microspheres,large amount of microspheres and high dosage of loaded drug have a higher risk of PES occurring after TACE.For patients having the above risk factors,the formulation of corresponding perioperative intervention strategies is necessary so as to avoid the occurrence of PES and to improve the safety of TACE.

Objective To analyze the relationships between pulmonary ground-glass nodules(GGN)and bronchi and blood vessels and their diagnostic values for infiltrative lesions based on high-resolution computed tomography(HRCT)target scanning technology.Methods Patients with GGN detected by HRCT target scanning and complete pathological results were retrospectively selected as the research subjects.The relationships between GGN and bronchi and blood vessels in patients with different pathological types were analyzed,and the relationships for detecting infiltrative lesions were further analyzed,using pathological results as the gold standard.Results Three hundred patients were divided into 237 cases of pre-invasive lesions and 63 cases of infiltrative lesions according to pathological results.There were statistically significant differences in lesion properties and lesion morphology in patients with different types of GGN(P＜0.05).There were statistically significant differences in the relationships between GGN and bronchi and blood vessels in the pre-invasive lesions and the infiltrative lesions(P＜0.05).Based on the pathological results as the gold standard,the sensitivity of HRCT bronchial classification,vascular classification,and their combined detection of infiltrative lesions were 84.13％(53/63),95.24％(60/63),and 95.24％(60/63);specificity were 83.12％(197/237),87.34％(207/237),and 87.34％(207/237);accuracy were 83.33％(250/300),89.00％(267/300),and 89.00％(267/300).Conclusion Evaluating the classification of pulmonary GGN and bronchi and blood vessels by HRCT target scanning technology has good value in identifying infiltrative lesions.The combined diagnosis of the two signs can further improve the accuracy of detection.

Vomiting and diarrhea of patients during PBDs 3 to 7 and PBDs 8 to 14 were recorded. Levels of serum albumin, prealbumin, blood glucose, and triglycerides, 24-hour excretion of urinary nitrogen, nitrogen balance values of patients on PBDs 7 and 14 were recorded or calculated. Data were processed with paired t test and chi-square test. Results: (1) The personal daily total energy intake of patients during PBDs 3 to 7 and PBDs 8 to 14 were (8 696±573) and (11 980±1 259) kJ respectively, and ratios of them to energy target [(13 290±1 561) kJ] were 65.4% and 90.1% respectively. The personal daily total energy intake of patients during PBDs 3 to 7 was obviously lower than that during PBDs 8 to 14 (t=18.172, P<0.01). (2) The personal daily intake of carbohydrate, fat, and protein of patients during PBDs 8 to 14 were obviously higher than those during PBDs 3 to 7 (t=15.628, 22.231, 10.403, P<0.01). The personal daily calorigenic percentages of carbohydrate, fat, and protein accounted for total energy intake of patients were 56.8%, 25.1%, and 18.3% respectively during PBDs 3 to 7 and 54.2%, 27.0%, and 18.7% respectively during PBDs 8 to 14. The calorigenic constituent ratio of personal daily intake of carbohydrate, fat, and protein accounted for total energy intake of patients during PBDs 3 to 7 was close to that during PBDs 8 to 14 (χ²=0.185, P>0.05). The ratios of non-protein calories to total nitrogen (kJ∶g) of patients during PBDs 3 to 7 and PBDs 8 to 14 were 469∶ 1 and 456∶ 1 respectively. (3) The personal daily energy intake of patients from routes of oral diet and parenteral nutrition preparations during PBDs 8 to 14 [(4 394±978), (5 723±898) kJ] were obviously higher than those during PBDs 3 to 7 [(2 137±453), (4 855±825) kJ, t=26.516, 6.583, P<0.01], while the personal daily energy intake of patients from routes of enteral nutrition preparations during PBDs 8 to 14 was close to that during PBDs 3 to 7 (t=1.922, P>0.05). The constituent ratio of personal daily energy during PBDs 3 to 7 was close to that during PBDs 8 to 14 (χ²=4.100, P>0.05). The personal daily protein intake of patients from route of oral diet during PBDs 8 to 14 was (58±22) g, obviously higher than (25±6) g during PBDs 3 to 7 (t=14.514, P<0.01). The personal daily protein intake of patients from routes of enteral nutrition preparations and parenteral nutrition preparations during PBDs 8 to 14 was close to those during PBDs 3 to 7 (t=1.924, 1.110, P>0.05). The constituent ratio of personal daily protein intake from routes of oral diet, enteral nutrition preparations, and parenteral nutrition preparations accounted for total protein intake during PBDs 8 to 14 was close to that during PBDs 3 to 7 (χ²=5.634, P>0.05). (4) There were 3 patients with vomiting and 4 patients with diarrhea during PBDs 3 to 7, and 1 patient experienced both of them during PBDs 8 to 14. The levels of serum albumin, prealbumin, blood glucose, and triglycerides, 24-hour excretion of urinary nitrogen, and nitrogen balance values of patients on PBDs 7 and 14 were (29±4) and (30±4) g/L, (132±42) and (171±48) mg/L, (7.4±2.8) and (6.7±2.8) mmol/L, (1.5±0.7) and (1.4±0.7) mmol/L, (30.5±4.3) and (34.5±2.2) g, -(25.1±2.6) and -(23.7±3.9) g, respectively. Conclusions The personal daily total energy intake of patients during PBDs 3 to 7 was lower than that during PBDs 8 to 14. The calorigenic constituent ratio of personal daily intake of carbohydrate, fat, and protein accounted for total energy of patients during PBDs 3 to 7 was close to that during PBDs 8 to 14. Energy and protein intake were mostly derived from parenteral nutrition preparations during PBDs 3 to 7, while those during PBDs 8 to 14 were mainly derived from parenteral nutrition preparations and oral diet.
