Objective To investigate the regrlative role of the cervical sympathetic ganglia on the cochlear blood flow and auditory function in guinea pig.Methods The horseradish peroxidase(HRP) was given to spiral modiolar artery locally for retrograde tracing in guinea pig. Immunohistochemical double-labeled technique was used in this study. The cochlear blood flow and auditory brainstem response(ABR) was measured a week after anilateral superior cervical sympathectony. The animal model of superior cervical sympathectomy following noise exposure in guinea pigs was estableshed to observe the auditory threshold shift.Results Retrogradely labeled neurons with HRP were found in the ipsilateral superior cervical ganglion(SCG). Most of HRP-labeled neurons in SCG were tyrosion hydroxylase(TH) positive. The blood flow of the capillaries of the stria vascularis on the experimental side a week ago were more aplenty than that of the opposite side, but the ABR threshold did not changed before and after ablation of the superior cervical ganglion.A protective role against noise injury was observed after surgical ablation of superior cervical ganglion.Conclusion The superior cervical sympathectomy can influence the cochlear blood flow and auditory function in guinea pig.

Objective To know the renal damage in cadmium (Cd) exposed residents in Cd polluted areas where polluted by Cd for 20 years. Methods The levels of urinary Cd (UCd), N-acetyl-beta-D-glucosaminidase (UNAG), ?2-microglobulin (UBMG), retinal binding protein (URBP), and albumin (UALB) were measured in 39, 65, 57, and 42 residents lived in the severe-, moderate-, light-, and non-polluted area respectively for more than 20 years. The test indexes were adjusted with urinary creatinine, and geometric means were statistically used. Results The levels of UCd in all subjects were obviously decreased compared with those in 1992, but the levels of UCd, UNAG, UBMG, and URBP and the abnormal rate of UNAG in residents in Cd-polluted areas were significantly higher than those in residents in non-polluted area (P

Objective:Proximal femur tumor resection often leads to hip joint instability and functional loss.Various methods have been clinically applied to repair hip joint soft tissue function,but deficiencies remain.This study aims to evaluate the advantages and disadvantages of the ligament advanced reinforcement system(LARS)tumor tube in assisting soft tissue function reconstruction in patients undergoing tumor type artificial hip replacement surgery. Methods:This study included 85 patients(41 males,44 females)with proximal femoral tumors treated at the Xiangya Bone Tumor Treatment Center from January 2012 to January 2022,aged 10 to 79(38.5±18.2)years.Among them,13 cases had benign aggressive tumors,45 had primary malignant bone tumors,and 27 had bone metastases.Clinical data,imaging data,and intraoperative photos were collected.Patients were followed up and postoperative functional evaluations were conducted using the Musculoskeletal Tumor Society(MSTS)scoring system and Harris hip joint scoring system to assess limb function and hip joint function. Results:Preoperative pathological fractures were present in 37 cases(43.5％),with a lesion length of(9.4±2.9)cm.Among non-metastatic tumor patients,7 experienced postoperative recurrence,including 6 cases of osteosarcoma and 1 case of fibrosarcoma.Pulmonary metastases occurred in 9 osteosarcoma patients.Five patients required reoperation due to postoperative complications,including 3 cases of deep vein thrombosis,1 case of giant cell granuloma,and 1 case of prosthesis infection.Postoperatively,5 patients exhibited Trendelenburg gait,and 6 had leg length discrepancies.The postoperative MSTS score was 26.7±1.4,and the Harris score was 89.6±5.3. Conclusion:The LARS tumor tube can effectively assist in reconstructing the soft tissue function of the hip joint and greatly reduce postoperative complications,making it an effective technical improvement in joint function reconstruction in tumor type artificial hip replacement surgery.

Objective:To investigate the blood flow change status in early stage tumor-related areas of hepatocellular carcinoma and its clinical significance after radiofrequency ablation using multi-slice spiral CT whole-liver perfusion imaging technology.Methods:21 cases of primary liver cancer that underwent CT-guided radiofrequency ablation were included. CT perfusion scans were divided into four groups according to the time points of CT scans (before surgery, immediately after surgery and 1 and 3 month after surgery), and then blood perfusion parameters of the corresponding areas of the tumor were measured. Statistical analysis was performed using two independent samples of non-parametric Wilcoxon rank-sum test. The differences of blood perfusion parameters between tumor or ablation lesion and background liver parenchyma, paratumor tissue or inflammatory response zone were compared before, immediately and 1 and 3 months after surgery, respectively.Results:(1) The hepatic arterial perfusion (HAP) and hepatic arterial perfusion index (HPI) of cancerous liver tumors and background liver parenchyma was significantly increased ( P < 0.01). The total liver perfusion (TLP) was higher than the background liver parenchyma ( P = 0.01 < 0.05). The time to peak (TTP) was significantly lower than background liver parenchyma ( P < 0.01); (2) The perfusion parameters of HAP, PVP and TLP were lower than the background liver parenchyma in the complete ablation lesions immediately after radiofrequency ablation and 1 and 3 months after surgery, and the difference was statistically significant ( P < 0.05); (3) The inflammatory response zone of ablation lesions of HAP, HPI, and TLP were gradually decreased with the extended postoperative time and TTP was gradually increased, while PVP did not change significantly; (4) HAP, HPI, and TTP were compared between the tumor and the tumor inflammatory response zone immediately after surgery, and 1 and 3 months after surgery, and the difference was statistically significant ( P < 0.01). However, there was no statistically significant difference between PVP and TLP ( P > 0.05). Conclusion:CT whole-liver perfusion imaging can precisely evaluate the early stage blood flow change status in peritumor and tumors before and after radiofrequency ablation and then objectively evaluate tumor’s blood supply and therapeutic effect on hepatocellular carcinoma.

OBJECTIVE To provide reference for constructing scientific and reasonable pharmaceutical service mode for hospitalized patients with chronic airway diseases. METHODS From October 2023 to March 2024， 250 patients with chronic obstructive pulmonary disease and acute exacerbation of asthma who were hospitalized in the respiratory department of Hebei General Hospital and received pharmaceutical care （PC） were randomly divided into control group （125 cases） and observation group （125 cases）. The control group received general pharmaceutical services throughout their hospitalization， while the observation group received standardized and graded pharmaceutical services throughout their hospitalization. The differences in clinical value indicators， humanistic value indicators， and quality management indicators were compared among different PC service models. RESULTS Among clinical value evaluation indicators， the observation group had better achievement rate of disease treatment goals， correct use score of inhalation devices， the incidence of adverse drug reactions， and the number of drug-related problems solved than the control group （P＜0.05）. Among the humanistic evaluation indicators， compared with the control group， the observation group had better medication compliance scores， pharmacist intervention success rates， and patient satisfaction scores （P＜0.05）. Among quality management evaluation indicators， the proportion of drug costs， the proportion of intravenous medication， the use rate of antibiotics， the intensity of antibiotic use， and the number of pharmaceutical services in the observation group were significantly better than the control group （P＜0.05）. CONCLUSIONS Standardized and graded pharmaceutical care services have improved the efficiency of pharmacists and service effectiveness， making it a new pharmaceutical service model worth promoting.

Objective: To investigate the distribution of traditional Chinese medicine (TCM) syndromes and syndrome elements in lymphoma, as well as the correlation between TCM syndromes and Western clinical indicators, in order to analyze associations between TCM syndromes and these indicators. Methods: From January 2023 to May 2024, 216 patients with lymphoma who met the inclusion criteria in the Department of Hematology, Third People′s Hospital Affiliated to Fujian University of Traditional Chinese Medicine were enrolled. Four diagnostic methods were applied to perform TCM syndrome differentiation and extract syndrome elements. The correlations between various syndromes and blood test indicators of lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), immunoglobulin G (IgG), immunoglobulin M (IgM), immunoglobulin A (IgA), white blood cell (WBC), hemoglobin (Hb), platelet count (PLT), neutrophil (NEUT), immunohistochemical markers of B-cell lymphoma-6 (BCL6), B-cell lymphoma-2 (BCL2), proto-oncogene MYC, and Ki67 protein expression, Ann Arbor staging, international prognostic index (IPI) score, bone marrow infiltration, concurrent infections during chemotherapy, and post-chemotherapy bone marrow suppression rate were analyzed. Results: Five TCM syndromes, ranked by frequency, were syndromes of yin deficiency with phlegm accumulation(41.67%), qi depression with phlegm obstruction(30.56%), cold-phlegm congelation and stagnation(12.96%), phlegm-blood stasis toxin(12.04%), and lingering pathogen due to deficient vital qi(2.77%). Yin deficiency(50.93%) and phlegm(45.37%) were the more prevalent syndrome elements. The TCM syndromes were correlated with β2-MG, PLT, MYC, BCL2/MYC, Ki67 protein expression, and bone marrow infiltration (P<0.05). No statistically significant differences were observed in Ann Arbor staging or IPI score across the syndromes. Compared to the syndrome of cold-phlegm congelation and stagnation, the syndrome of qi depression with phlegm obstruction exhibited higher levels of NEUT, MYC, BCL2/MYC, and Ki67 protein expression, as well as a higher rate of post-chemotherapy bone marrow suppression (P<0.05); the syndrome of phlegm-blood stasis toxin showed higher MYC and BCL2/MYC protein expression and a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05); the syndrome of yin deficiency with phlegm accumulation demonstrated higher MYC and BCL2/MYC protein expression and bone marrow infiltration rates, whereas PLT level was lower (P<0.05); the syndrome of lingering pathogen due to deficient vital qi had higher MYC, BCL2/MYC, and Ki67 protein expression levels, as well as a higher rate of post-chemotherapy bone marrow suppression rate (P<0.05). Compared to the syndrome of qi depression with phlegm obstruction, the syndrome of phlegm-blood stasis toxin exhibited lower Ki67 protein expression (P<0.05); the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, bone marrow infiltration rate, and rate of concurrent infections during chemotherapy, whereas PLT and NEUT levels and the rate of post-chemotherapy bone marrow suppression rate were lower (P<0.05). Compared to the syndrome of phlegm-blood stasis toxin, the syndrome of yin deficiency with phlegm accumulation had higher β2-MG level, whereas NEUT and the rate of post-chemotherapy bone marrow suppression were lower(P<0.05); the syndrome of lingering pathogen due to deficient vital qi exhibited a higher Ki67 protein expression (P<0.05). Compared to the syndrome of yin deficiency with phlegm accumulation, the syndrome of lingering pathogen due to deficient vital qi also showed a higher Ki67 protein expression(P<0.05). Conclusion The syndrome of yin deficiency with phlegm accumulation is relatively common in lymphoma. There is a correlation between TCM syndromes and Western medicine clinical indicators. The presence of heat signs in the syndromes may indicate active disease and poor prognosis, while the presence of strong pathogenic factors and weak vital qi in the syndromes may indicate a severer chemotherapy-related bone marrow suppression.

Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease， making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine （TCM） in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation， using standardized measurements of the overall TCM condition， multi-omics research of hematologic tumors， and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma， thereby establishing a risk warning system for virus-related lymphoma. At the same time， a TCM health management approach will be applied to manage and regulate virus-related lymphoma， interrupting its progression and forming a human-centered， comprehensive， continuous health service model. Based on this， a standardized， integrated clinical prevention and treatment decision-making model for virus-related lymphoma， recognized by both Chinese and western medicine， will be established to provide TCM solutions for primary prevention of major malignant tumors.
