Objective To explore the effect of community pharmacy outpatient service on patients with type 2 diabetes mellitus. Methods A non-randomized controlled study was conducted, and type 2 diabetes patients managed in the community were divided into an intervention group of 112 cases and a control group of 110 cases. The control group received routine medication guidance during general practice outpatient visits, while the intervention group received comprehensive pharmacy outpatient service intervention based on routine medication guidance in general practice. Follow-up visits were conducted every 3 months. Repeated measurement analysis of variance and multivariate linear regression analysis were used to evaluate the intervention effect of the pharmacy outpatient service. Results Fasting blood glucose and glycosylated hemoglobin levels in the intervention group showed a decreasing trend with the increase of intervention time compared to pre-intervention time （P<0.01）, with increased duration of weekly exercise, decreased staple food intake, increased vegetable intake, and increased medication adherence score （P<0.01）. After adjusting for confounding factors through multivariate linear regression model, pharmacy outpatient intervention was found to be an independent protective factor for fasting blood glucose level （β=−0.891, P<0.01） and glycosylated hemoglobin level （β=−0.760, P<0.01） in the study subjects. Conclusion The community pharmacy outpatient service could enhance the self-management ability of patients with type 2 diabetes mellitus, and effectively improve patients’ fasting blood glucose and glycosylated hemoglobin.

Objective To investigate the effects and underlying mechanisms of a spray prepared from exosomes derived from M2 macrophages induced by interleukin-4 （IL-4） and tantalum particles （Ta） on the healing of pressure ulcers. Methods Bone marrow-derived macrophages were polarized into M2 macrophages using IL-4 or Ta, and exosomes （Exo-IL-4/Exo-Ta） were extracted. The regulatory effects of Exo-IL-4/Exo-Ta on M1 macrophage phenotypes and fibroblast matrix secretion were evaluated in vitro. Proteomic analysis was conducted to explore the biological processes and regulatory networks associated with Exo-Ta. A rat pressure ulcer model was used to assess the effects of Exo-IL-4/Exo-Ta spray on wound healing rate, inflammatory cell infiltration, and collagen deposition. Results In vitro, Exo-IL-4/Exo-Ta induced the polarization of M1 macrophages to M2 macrophages, reduced the secretion of pro-inflammatory factors, and promoted the expression of anti-inflammatory substances. Additionally, Exo-IL-4/Exo-Ta enhanced the production of collagen and fibronectin in fibroblasts. Proteomic analysis revealed that Exo-Ta primarily participated in biological processes such as energy metabolism and macromolecule biosynthesis. In vivo, Exo-IL-4/Exo-Ta spray accelerated wound healing, reduced inflammatory infiltration, and improved tissue remodeling in the rat pressure ulcer model. Conclusion Exosome sprays derived from M2 macrophages could accelerate pressure ulcer healing by modulating inflammation and promoting tissue regeneration, which demonstrated excellent clinical application potential.

Objective To investigate the impact of continuous nebulization therapy after lung transplantation on pulmonary function and related complications in lung transplant recipients. Methods A retrospective analysis was conducted on the general data of 71 recipients who underwent allogeneic lung transplantation at the Department of Thoracic Surgery, the First Affiliated Hospital of Zhengzhou University, from June 2013 to December 2024. Recipients were divided into observation group (those who continued nebulization therapy for more than 3 months after discharge) and control group (those who discontinued nebulization therapy on their own). The main observation indicators were pulmonary function indicators at 6 months after surgery, including forced expiratory volume in the first second as a percentage of predicted value (FEV₁% pred), forced vital capacity as a percentage of predicted value (FVC% pred), ratio of forced expiratory volume in the first second to forced vital capacity as a percentage of predicted value (FEV₁/FVC% pred), forced expiratory flow at 25%, 50% and 75% of forced vital capacity as a percentage of predicted value, and the percentage of predicted value of corrected carbon monoxide diffusion capacity measured by single-breath method, as well as the ratio of corrected carbon monoxide diffusion capacity to alveolar volume as a percentage of predicted value. Additionally, the annual incidence of postoperative pulmonary infections, survival rate and the rate of no severe airway complications were analyzed. Results At 6 months after lung transplantation, the FEV₁% pred and FVC% pred of the observation group were better than those of the control group [FEV₁% pred was 76% (60%, 91%) vs. 67% (62%, 78%), FVC% pred was (75 ± 13)% vs. (69 ± 11)%, both P<0.05]. The observation group had a lower annual incidence of pulmonary infections compared to the control group (P = 0.023), with a risk of 0.485 times that of the control group. There were no statistically significant differences between the two groups in median survival time and the rate of no severe airway complications (both P>0.05). Conclusions Continuous nebulization therapy after lung transplantation may effectively improve pulmonary function, reduce the annual incidence of pulmonary infections, and play a positive role in the long-term maintenance of pulmonary function.

OBJECTIVE: To summarize the effectiveness of orthopedic surgery for patients with moderate and severe hallux valgus and analyze its related influencing factors. METHODS: A clinical data of 247 patients (287 feet) with moderate and severe hallux valgus, who were admitted between January 2013 and October 2024 and met the selection criteria, was retrospectively analyzed. There were 39 males and 208 females, with a median age of 57 years (range, 19-89 years). There were 207 cases of single-foot involvement and 40 cases of double-foot involvement; 159 feet were moderate hallux valgus and 128 feet were severe hallux valgus. The disease duration ranged from 3 months to 25 years, with a median of 5 years and 8 months. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), proximal articular set angle (PASA), and the American Orthopaedic Foot and Ankle Society (AOFAS) scores were measured before operation and at 6 months after operation, and the differences (change values) between pre- and post-operation were calculated. All patients were grouped according to the degree of preoperative hallux valgus deformity and age, and the patients with severe hallux valgus according to different surgical procedures, and the change values of HVA, IMA, and AOFAS scores were compared between groups. All patients were grouped according to postoperative HVA, then the postoperative AOFAS scores were compared between groups. RESULTS: All patients successfully completed the operations and were followed up 6 months to 11 years and 3 months, with an average of 4 years and 6 months. The HVA, IMA, PASA, and AOFAS scores at 6 months after operation showed significant improvement compared to preoperative levels, and the differences were significant ( P<0.05). The patients with severe hallux valgus had the higher change values of HVA, IMA, and AOFAS scores than the patients with moderate hallux valgus ( P<0.05). The elderly patients had the highest change values of HVA and AOFAS scores than the young and middle-aged patients ( P<0.05). The patients with postoperative HVA ranging from 0° to 5° had the highest AOFAS scores than the other patients at 6 months after operation ( P<0.05). Among different surgical procedures for severe hallux valgus, the metatarsophalangeal joint fusion had the highest change value of HVA, the Scarf osteotomy had the highest performance in correcting the IMA, and the first metatarsal base osteotomy had the highest improvement in the postoperative AOFAS score, and the differences were significant ( P<0.05). CONCLUSION Elderly patients show the better improvement in HVA and foot function after operation. The first metatarsal base osteotomy show the better improvement in foot function than other surgical procedures. A certain HVA is allowed to remain after hallux valgus correction, and the postoperative AOFAS score is higher when the corrected HVA is in the range of 0°-5°.

OBJECTIVES: To assess the biomechanical performance of a novel bridging plate for treating Rockwood III acromioclavicular joint dislocation. METHODS: A novel bridging plate structure was designed based on CT data from a patient with Rockwood type III acromioclavicular joint dislocation, and a finite element model of the bridging plate-acromioclavicular joint interaction was constructed. The stress and deformation characteristics and biomechanical compatibility of the plate under post-reduction, normal loading, and impact loading conditions were analyzed to evaluate its fixation mechanism and clinical advantages. RESULTS: The stiffness of the bridging system was 27.78 N/mm, close to that of acromioclavicular joint ligaments (26.05 N/mm) and meeting the requirements for flexible deformation. Under normal loading, the maximum stress in the bridging system was 88.29 MPa to sustain physiological activities; under impact loading, the maximum stress reached 480 MPa, and the cable underwent plastic deformation to dissipate energy and effectively buffer local stress concentrations, thereby reducing the risk of rigid bone fractures. The high-stress regions in the bone primarily occurred at the edges of the C1-C4 screw holes. The maximum bone stress was 0.762 MPa under normal loading and 5.963 MPa under impact loading, accounting for 2.86% and 1.66% of the corresponding bolt stresses, respectively. CONCLUSIONS The novel bridging plate is better adapted to biomechanical characteristics of the acromioclavicular joint compared to traditional internal fixation. This fixation system provides sufficient stability while allowing physiological micromotion to facilitate postoperative rehabilitation. Significant flexible deformation can occur at the connection between the fixation ring and the cable, and brittle materials should not be used in this region. The issue of stress concentration at the C1-C4 screw holes requires special attention in its clinical application.

OBJECTIVES: To evaluate the protective effect of Bufei Yishen Formula (BYF) against cigarette smoke extract (CSE)-induced injuries in human bronchial epithelial BEAS-2B cells and explore the underlying mechanism. METHODS: BEAS-2B cells exposed to CSE were treated with normal rat serum, BYF-medicated rat serum at low or high doses, pyrrolidine dithiocarbamate (PDTC, a NF-κB inhibitor), PDTC combined with high-dose BYF-medicated serum, or S-carbomethyloysteine (S-CMC, as the positive control). CCK-8 assay was used to determine the optimal concentration and treatment time of CSE, BYF-medicated serum and S-CMC. The treated cells were examined for inflammatory factor levels in the supernatant and cellular expressions of MUC5AC and MUC5B using ELISA, cell ultrastructural changes with transmission electron microscopy, and cell apoptosis rate using flow cytometry. The expression levels of TLR4/NF‑κB pathway-associated mRNAs and proteins were determined by qRT-PCR and Western blotting. RESULTS: CSE exposure significantly increased secretions of IL-1β, IL-6 and TNF-α, mRNA and protein expressions of MUC5AC and MUC5B, and early and total apoptosis rates in BEAS-2B cells, where the presence of apoptotic bodies was detected. CSE also significantly enhanced the mRNA and protein expressions of TLR4, I-κB, and NF-κB and reduced mRNA and protein expressions of AQP5. Treatments of the CSE-exposed cells with BYF-medicated serum, PDTC and S-CMC all significantly lowered inflammatory factor levels, MUC5AC and MUC5B expressions, and early and total cell apoptosis rates, and partly reversed the changes in cellular ultrastructure and mRNA and protein expressions of the TLR4/NF-κB pathway, and the effects were the most conspicuous following the combined treatment with high-dose BYF-medicated serum and PDTC. CONCLUSIONS BYF can inhibit cell apoptosis, inflammation and mucus hypersecretion in CSE-induced BEAS-2B cells by inhibiting the TLR4/NF-κB signaling pathway.

Objective To evaluate the clinical efficacy of Chu-Needle Therapy combined with Kang'ai Injection in treating cancer-related fatigue(CRF)in colorectal cancer patients with qi-blood deficiency syndrome.Methods Eighty patients diagnosed with colorectal cancer accompanied by CRF and qi-blood deficiency syndrome were enrolled from the inpatient and outpatient departments of Guangdong Second Traditional Chinese Medicine Hospital between January 2023 and March 2024.Participants were randomly divided into an observation group(n=40)and a control group(n=40)using a random number table.The control group received Kang'ai Injection alone,while the observation group received additional Chu-Needle Therapy.Treatment courses lasted 7 days each,with two consecutive courses administered.After two weeks,clinical efficacy was evaluated by comparing Revised Piper Fatigue Scale scores,traditional Chinese medicine(TCM)syndrome scores,as well as red blood cell count(RBC),hemoglobin(HGB),and albumin(ALB)levels,and immune markers(CD3+,CD4+,CD8+,NK cells)before and after treatment.Safety and adverse reactions were also assessed.Results(1)After treatment,both groups showed significant improvements in all Piper Fatigue Scale(PFS)scores,including behavioral,sensory,affective,and cognitive dimensions,as well as total scores(P＜0.05).The observation group demonstrated significantly greater improvements in all PFS subscales and total scores compared to the control group,with statistically significant differences(P＜0.05).(2)After treatment,both groups exhibited marked reductions in TCM syndrome scores,including fatigue,palpitations,shortness of breath,pale complexion,dizziness,spontaneous or night sweating,limb numbness,poor appetite,pale nails,and total scores(P＜0.05).The observation group showed significantly better improvement in all TCM syndrome scores than the control group,with statistically significant differences(P＜0.05).(3)The total effective rate was 82.5％(33/40)in the observation group versus 40.00％(16/40)in the control group,indicating significantly superior therapeutic efficacy in the observation group,with statistically significant differences(P＜0.05).(4)After treatment,both groups demonstrated significant improvements in RBC,HGB,ALB levels(P＜0.05),with the observation group showing significantly greater improvements in these hematological parameters compared to the control group,with statistically significant differences(P＜0.05).(5)After-treatment,both groups showed significant changes in immune markers CD3+,CD4+,CD8+,or NK cells compared to baseline(P＜0.05).The observation group exhibited significantly better modulation of CD3+,CD4+,CD8+,and NK cell levels than the control group,with statistically significant differences(P＜0.05).(6)The incidence of adverse reactions was 5.00％(2/40)in the observation group versus 22.50％(9/40)in the control group,indicating significantly better safety profile in the observation group,with statistically significant differences(P＜0.05).Conclusion Chu-Needle Therapy combined with Kang'ai Injection significantly alleviates fatigue,improves clinical symptoms,enhances nutritional status and immune function,and elevates quality of life in colorectal cancer patients with CRF and qi-blood deficiency syndrome,demonstrating notable clinical efficacy.

Objective:To evaluate the role of cancerous inhibitor of protein phosphatase 2A (CIP2A) in preoperative sleep deprivation (PSD)-induced aggravation of postoperative cognitive dysfunction (POCD) in aged mice.Methods:One hundred and ten healthy C57BL/6J mice of either sex, aged 18-20 months, weighing 29-35 g, were divided into 5 groups ( n=22 each) using a random number table method: sham operation group (S group), abdominal surgery group (O group), PSD + abdominal surgery group (D+ O group), CIP2A shRNA + abdominal surgery group (CS+ O group), and CIP2A shRNA+ PSD+ abdominal surgery group (CS+ D+ O group). At 14 days before surgery, control shRNA lentivirus was injected into the hippocampus in S, O and CS+ O groups, and CIP2A shRNA was injected into the hippocampus in D+ O and CS+ D+ O groups. PSD was carried out for 3 consecutive days prior to surgery. Cognitive function was assessed using the Morris water maze test at days 7-11 after surgery. The mice were sacrificed under deep anesthesia at day 3 after surgery, and hippocampal tissues were obtained to determine the expression of CIP2A, high mobility group box 1 (HMGB1), ionized calcium-binding adapter molecule 1 (Iba-1), alpha subunit of protein phosphatase 2A (PP2Aa), catalytic subunit of protein phosphatase 2A (PP2Ac), phosphorylated tau protein (p-tau) (S396), and p-tau (S404) (by Western blot), levels of reactive oxygen species (ROS), malondialdehyde (MDA), and superoxide dismutase (SOD), and count of Iba-1 positive cells in the hippocampal CA1 region (using immunofluorescence staining). Results:Compared with S group, the escape latency was significantly prolonged, the frequency of crossing the platform was reduced, duration of stay in the target quadrant was shortened, the expression of CIP2A, Iba-1 and HMGB1 was up-regulated, PP2Ac expression was down-regulated, levels of ROS and MDA and count of Iba-1 positive cells were increased, and the activity of SOD was decreased in O group ( P<0.05). Compared with O group, the escape latency was significantly prolonged, the frequency of crossing the platform was reduced, duration of stay in the target quadrant was shortened, the expression of CIP2A, Iba-1 and HMGB1 was up-regulated, PP2Ac expression was down-regulated, levels of ROS and MDA and count of Iba-1 positive cells were increased, and the activity of SOD was decreased in D+ O group, and the escape latency was significantly shortened, the frequency of crossing the platform was increased, duration of stay in the target quadrant was prolonged, the expression of CIP2A, Iba-1 and HMGB1 was down-regulated, PP2Ac expression was up-regulated, levels of ROS and MDA and count of Iba-1 positive cells were decreased, and the activity of SOD was increased in CS+ O group ( P<0.05). Compared with D+ O group, the escape latency was significantly shortened, the frequency of crossing the platform was increased, duration of stay in the target quadrant was prolonged, the expression of CIP2A, Iba-1 and HMGB1 was down-regulated, PP2Ac expression was up-regulated, levels of ROS and MDA and count of Iba-1 positive cells were decreased, and the activity of SOD was increased in CS+ D+ O group ( P<0.05). There was no significant difference in PP2Aa expression among the five groups ( P>0.05). Conclusions:The mechanism by which PSD aggravates POCD is related to up-regulating the expression of CIP2A and promoting oxidative stress responses, neuroinflammatory responses and phosphorylation of tau protein in aged mice.

Objective:To measure the overall and lobulated volume of the liver with different degrees of liver fibrosis and to further observe pathological changes such as liver microvasculature, hepatocyte apoptosis, and regeneration in order to understand the macroscopic volume changes of the liver during liver fibrosis and its relationship with liver tissue microscopic pathology in patients with chronic liver disease.Methods:53 patients with chronic hepatitis B, alcoholic fatty liver disease, autoimmune liver disease, nonalcoholic fatty liver disease, and drug-induced chronic liver disease who underwent both liver biopsy tissue and abdominal magnetic resonance imaging were collected. Patients were divided into early (F1-2), middle (F3-4), and late (F5-6) in accordance with the Ishak fibrosis stage and Masson stain. The liver and spleen volumes were measured using ITK-SNAP software. CD31 immunohistochemical staining was used to reflect intrahepatic angiogenesis. Ki67 and HNF-4α multiplex immunohistochemical staining were used to reflect hepatocyte regeneration. GS staining was used to determine parenchymal extinction lesions. TUNEL staining was used to observe hepatocyte apoptosis. Spearman correlation analysis was used to analyze the relationship between liver volume changes and liver histopathological changes.Results:As liver fibrosis progressed, the total liver volume and right lobe liver volume gradually decreased ( P<0.05), while the spleen volume gradually increased ( P<0.05). The expression of CD31 and GS gradually increased ( P<0.05), and the expression of Ki67 first increased and then decreased ( P<0.05). The positivity rate of CD31 was negatively correlated with the right lobe liver volume ( r=-0.609, P<0.001) and the total liver volume ( r=-0.363, P=0.017). The positivity rate of Ki67 was positively correlated with the right lobe liver volume ( r=0.423, P=0.018), while the positivity rate of apoptotic cells was significantly negatively correlated with the total liver volume ( r=-0.860, P<0.001). The positivity rate of GS was negatively correlated with the right lobe liver volume ( r=-0.440, P=0.002), and the number of PELs was negatively correlated with RV ( r=-0.476, P=0.013). The CD31 positive staining area was negatively correlated with the Ki67 positive staining area( r=-0.511, P=0.009). Conclusion:As liver fibrosis progresses, patients with chronic liver disease have a depletion in total liver volume and right lobe liver volume, and this is mainly in correlation with fewer liver cells and liver tissue microvasculature disorders.
