ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.

PURPOSE: Static progressive stretch (SPS) can be applied to treat chronic joint stiffness. However, the impacts of subacute application of SPS to the distal lower limbs, where deep vein thrombosis (DVT) is common, on venous thromboembolism remain unclear. This study aims to explore the risk of venous thromboembolism events following subacute application of SPS. METHODS: A retrospective cohort study was conducted on patients diagnosed with DVT following a lower extremity orthopedic surgery before being transferred to the rehabilitation ward from May 2017 to May 2022. Patients with unilateral lower limb comminuted para-articular fractures, transferred to rehabilitation ward for further treatment within 3 weeks after operation, followed up more than 12 weeks since initial manual physiotherapy, and diagnosed DVT by ultrasound before rehabilitation course were included in the study. Patients with polytrauma, without evidence of previous peripheral vascular disease or incompetence, had medication for thrombosis treatment or prophylaxis before the operation, detected with paralysis due to nervous system impairment, infected after operation during the regime, or with acute progression of DVT were excluded. The included patients were randomized to the standard physiotherapy and the SPS integrated groups for observation. Associated DVT and pulmonary embolism data were collected during the physiotherapy course to compare the groups. SSPS 28.0 and GraphPad Prism 9 were used for data processing. A p < 0.05 was set significant difference. RESULTS: In total of 154 patients with DVT participating in this study, 75 of them were treated with additional SPS for postoperative rehabilitation. The participants in the SPS group showed improved range of motion (12.3° ± 6.7°). However, in the SPS group, there was no difference in thrombosis volume between the start and termination (p = 0.106, p = 0.787, respectively), although difference was seen intra-therapy (p < 0.001). Contingency analysis revealed the pulmonary embolism incidence (OR = 0.703) in the SPS group compared to the mean physiotherapy. CONCLUSION The SPS technique is a safe and reliable option to prevent potential joint stiffness without aggravating the risk of distal DVT for postoperative patients suffering from relevant trauma.

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m², fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m², male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

Accurate assessment of the risks associated with traditional Chinese medicine(TCM), such as the potential to induce serious cardiovascular adverse reactions including cardiac arrhythmias, is crucial. This article introduced the pharmacological evaluation strategies for cardiac safety and the progress in cardiac organ research, with a focus on discussing the application prospects of human induced pluripotent stem cells(hiPSCs) and organoids in assessing the risks of TCM-induced cardiac arrhythmias. Compared with traditional animal models, hiPSCs and organoid models provide better reference and predictive capabilities, allowing for more accurate simulation of human cardiac responses. Researchers have successfully generated various cardiac tissue models that mimic the structure and function of the heart to evaluate the effects of TCM on the heart. The hiPSCs model, by reprogramming adult cells into pluripotent stem cells and differentiating them into cardiac cells, enables the generation of personalized cardiac tissue, which better reflects individual differences and drug responses. This provides guidance for the assessment of TCM cardiac toxicity risks. By combining organoid model with cardiac safety pharmacology strategies such as electrocardiogram monitoring and ion channel function assessment, the impact of TCM on the heart can be comprehensively evaluated. In addition, the application of the Comprehensive in Vitro Proarrhythmia Assay(CiPA) approach improves the accuracy of evaluation. Applying the CiPA approach to TCM research reveals potential risks and provides a scientific basis for the clinical application and industrial development of TCM. In conclusion, organoid model and cardiac safety pharmacology evaluation strategies provide important tools for assessing the cardiac toxicity risks of TCM. The combination of hiPSCs model, comprehensive assessment methods, and the CiPA strategy enables an accurate assessment of the risks of TCM-induced cardiac arrhythmias, thus providing a scientific basis for the safe use and international recognition of TCM in clinical practice. This contributes to ensuring the safety and efficacy of TCM and promoting its clinical application and global acceptance.

OBJECTIVE: To evaluate whether electroacupuncture (EA) would improve gastrointestinal function and clinical prognosis in patients with severe traumatic brain injury (TBI) complicocted by acute gastrointestinal injury (AGI). METHODS: This multicenter, single-blind trial included patients with TBI and AGI admitted to 5 Chinese hospitals from September 2018 to December 2019. A total of 500 patients were randomized to the control or acupuncture groups using a random number table, 250 cases in each group. Patients in the control group received conventional treatment, including mannitol, nutritional support, epilepsy and infection prevention, and maintenance of water, electrolytes, and acid-base balance. While patients in the acupuncture group received EA intervention at bilateral Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Tianshu (ST 25), and Zhongwan (RN 12) acupoints in addition to the conventional treatment, 30 min per time, twice daily, for 7 d. The primary endpoint was 28-d mortality. The secondary endpoints were serum levels of D-lactic acid (D-lac), diamine oxidase (DAO), lipopolysaccharide (LPS), motilin (MTL) and gastrin (GAS), intra-abdominal pressure (IAP), bowel sounds, abdominal circumference, AGI grade, scores of gastrointestinal failure (GIF), Glasgow Coma Scale (GCS), Acute Physiology and Chronic Health Evaluation (APACHE II), Sequential Organ Failure Assessment (SOFA), and Multiple Organ Dysfunction Syndrome (MODS), mechanical ventilation time, intense care unit (ICU) stay, and the incidence of hospital-acquired pneumonia. RESULTS: The 28-d mortality in the acupuncture group was lower than that in the control group (22.80% vs. 33.20%, P<0.05). Compared with the control group, the acupuncture group at 7 d showed lower GIF, APACHE II, SOFA, MODS scores, D-lac, DAO, LPS, IAP, and abdominal circumference and higher GCS score, MTL, GAS, and bowel sound frequency (all P<0.05). In addition, the above indices showed simillar changes at 7 d compared with days 1 and 3 (all P<0.05) in the EA group. CONCLUSION Early EA can improve gastrointestinal function and clinical prognosis in patients with severe TBI complicated by AGI. (Registration No. ChiCTR2000032276).

Objective To investigate the expression levels of microRNA(miR)-191,miR-23a,and miR-145 in plasma of patients with prostate cancer and their correlation with prognosis.Methods Sixty prostate cancer patients admitted to Zhumadian Central Hospital from December 2019 to December 2021 were selected as the observation group,and 60 healthy subjects who underwent physical examinations during the same period were selected as the control group.The expression levels of miR-191,miR-23a and miR-145 in plasma of subjects in the two groups were measured by real-time fluorescence quantita-tive polymerase chain reaction.The patients in the observation group were divided into poor prognosis group(n=11)and good prognosis group(n=49)according to their prognosis.The expression levels of miR-191,miR-23a,and miR-145 in plasma of prostate cancer patients were compared before and after treatment.The general data of patients was compared between the poor prognosis group and the good prognosis group.The receiver operator characteristic curve was drawed to analyse the predictive value of plasma miR-191,miR-23a,and miR-145 levels on prognosis.Results The relative expression levels of miR-191 and miR-23 a in plasma of patients in the observation group were significantly higher than those in the control group,while the relative expression level of miR-145 was significantly lower than that in the control group(P＜0.05).The relative expression levels of miR-191 and miR-23a of patients in the observation after treatment were significantly lower than those before treat-ment,while the relative expression level of miR-145 was significantly higher than that before treatment(P＜0.05).There was no significant difference in age,body mass index,smoking history,alcohol consumption history,and prostate volume of patients between the poor prognosis group and the good prognosis group(P＞0.05);there was significant differences in TNM staging,Gleason score,serum prostate specific antigen level and relative expressions of miR-191,miR-23a,miR-145 in plasma of patients between the two groups(P＜0.05).Plasma miR-191,miR-23a and miR-145 levels were influence factor for prognosis in patients with prostate cancer(P＜0.05).There was predictive value of plasma miR-191,miR-23a and miR-145 for prognosis of prestate cancer patients;the combined predictive value of plasma miR-191,miR-23a and miR-145 for the prognosis of prostate cancer patients was significantly higher than that of plasma miR-191,miR-23a and miR-145 alone for the prognosis of prostate cancer patients(P＜0.05).Conclusion The expression of miR-191 and miR-23a in plasma increases and the expression of miR-145 in plasma decreases in patients with prostate cancer.The combined detection of plasma miR-191,miR-23a and miR-145 has higher predictive value for the prognosis of prostate cancer.

Aim To study the antitumor effect of cispl-atin ( DDP) chemotherapy promoted by Taohong Siwu Decoction (TSD) on mice with lung adenocarcinoma mice. Methods Lewis lung carcinoma cell line was used to make homologous lung adenocarcinoma trans¬plantation mouse model. Normal control, Model, TSD, DDP, TSD + DDP groups were set up. The change of transplanted tumor volume after administration was observed, the weight of transplanted tumor was weighed, the expression of Ki67 in transplanted tumor tissue was detected by immunohistochemistry, TUNEL was detected by fluorescence staining, Bcl-2, Bax, cleaved Caspase-3 and cleaved Caspase-9 were detected by immunoblotting, and the content of D-dirtier in plasma was measured by ELISA. Results DDP plus TSD significantly inhibited the growth of transplanted tumor. Ki67 expression in tumor tissue was lower than that in DDP group (28. 3% ±3. 1% vs 40. 3% ±2.1% ). The combined use of TSD and DDP significantly promoted the apoptosis level of transplanted tumor. The positive rate of TUNEL was significantly higher than that of DDP group (41. 0% ±3.0% vs 30.7% ± 4.5%). Bax, cleaved Caspase-3 and cleaved Caspase-9 expressions in tumor tissue were also higher than those of DDP group, while the expression of Bcl-2 was significantly lower than that of DDP group. Moreover, we found a significant interaction between TSD and DDP on the expression of four apoptotic proteins ( P < 0.05 ) . The plasma D-dimer content in TSD + DDP group was significantly lower than that in DDP group (188. 50 ± 28. 46 vs 269.80 ± 35.92) μg • L
