Objective To investigate the relationship between primary pulmonary mucinous adenocarcinoma (PPMA) mass type and pneumonia type and their difference in malignant degree, and to analyze the role of clinical manifestations and CT features in the diagnosis of this disease. Methods The clinical data of PPMA patients admitted in the First Affiliated Hospital of Xiamen University from May 2011 to March 2022 were retrospectively analyzed. According to CT features, they were divided into a mass type group and a pneumonia type group. The clinical manifestations, CT features and the degree of malignancy between the two groups were analyzed and compared. Results A total of 57 PPMA patients were enrolled. There were 17 males and 40 females, with an average age of (53.82±10.65) years, and 28 (49%) patients had reversed hato-like sign. There were 42 patients in the mass type group and 15 patients in the pneumonia type group. PPMA often occurs in both lower lungs, with clinical manifestations mainly of coughing and expectorating white mucoid sputum. There were statistical differences between the two groups in the maximum diameter of tumor (P<0.001), boundary condition (P<0.001) and pleural indentation sign (P=0.019). There was no statistical difference between the two groups in Ki-67 index (P>0.05). Conclusion There is no statistical difference in the degree of malignancy between the two types of PPMA. Considering their clinical manifestations and differences in imaging features, it is supported that the pneumonia type is just a progression of the mass type. CT can present various manifestations, among which the reversed hato-like sign is expected to become an important imaging feature. Combined with a high proportion of solid components, pleural indentation sign, and vacuole sign, reversed hato-like sign can play a significant role in the diagnosis of PPMA.

ObjectiveTo investigate the role and mechanism of Go-Ichi-Ni-San complex subunit 1 （GINS1） in the progression of hepatocellular carcinoma （HCC） and the development of chemotherapy resistance. MethodsThe tumor database GEPIA2 was used to analyze the differential expression of GINS1 between HCC patients and healthy individuals， and pathological tissue samples were collected from 40 HCC patients who were admitted to The Affiliated Tumor Hospital of Xinjiang Medical University and the First Affiliated Hospital of Xinjiang Medical University from May 2017 to January 2021. Immunohistochemical staining was used to measure the difference in the expression of GINS1 between HCC tissue and corresponding adjacent tissue， and the correlation between the expression level of GINS1 and the clinical TNM stage of HCC was analyzed. Western blot was also used to measure the difference in the expression of GINS1 between HCC Huh7/Hep3B/Li-7/MHCC97H cell lines and normal human QSG7701 hepatocytes. The method of lentivirus transfection was used to establish the MHCC97H cell line with stable GINS1 knockdown and its negative control cell line. CCK-8 assay and colony formation assay were used to measure cell proliferative capacity； scratch assay was used to measure cell migration ability； Transwell assay was used to measure cell invasion ability； cells were treated with oxaliplatin to measure their sensitivity to chemotherapy drugs. Nude mice were used to establish a tumor-bearing model and observe the effect of GINS1 knockdown on the growth of HCC in vivo. Western Blot was used to measure the expression levels of the proteins associated with the Notch pathway and the JAK/STAT pathway. The cells were treated with the Notch receptor agonist Jagged-1 to analyze the association between GINS1 and the Notch/JAK/STAT pathway. The independent-samples t test was used for comparison of continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsThe expression of GINS1 was upregulated in HCC patients， HCC tissue， and HCC cell lines （all P<0.05）， and the expression level of GINS1 was positively correlated with the clinical TNM stage of HCC （r=0.822， P=0.011）. Compared with the negative control cells， the GINS1-knockdown MHCC97H cells showed significant reductions in proliferation， migration， and invasion activities （all P<0.01） and a significantly enhanced sensitivity to oxaliplatin （P<0.01）. Compared with the nude mice in the control group， GINS1 knockdown caused significant inhibition of tumor weight and volume in vivo in nude mice （all P<0.001）. Compared with the negative control cells， the GINS1-knockdown MHCC97H cells showed significant reductions in the expression levels of Notch1， Notch3， p-JAK2， and p-STAT3 （all P<0.05）， while there were no significant differences in the overall expression levels of JAK2 and STAT3 （P>0.05）. After Jagged-1 treatment， the GINS1-knockdown MHCC97H cells showed significant increases in proliferation， migration， and invasion activities and a significant reduction in sensitivity to oxaliplatin， as well as significant increases in the levels of p-JAK2 and p-STAT3 （all P<0.05）. ConclusionGINS1 is upregulated in HCC and can promote HCC progression and chemotherapy resistance through the Notch/JAK2/STAT3 pathway.

OBJECTIVE: To investigate the potential mechanism by which electroacupuncture (EA) induces macrophage polarization to promote muscle satellite cell proliferation and differentiation, accelerating the repair of acute skeletal muscle injury. METHODS: Forty-two SPF-grade SD rats were randomly divided into three groups: a blank group (n=6), a model group (n=18), and an EA group (n=18). The model and EA groups established acute blunt contusion model of the right gastrocnemius muscle using a self-made striking device. From day 1 after modeling, rats in the EA group received EA at "Chengshan" (BL57) and "Yanglingquan" (GB34) on the right side, using disperse-dense wave with a frequency of 2 Hz/100 Hz and a current of approximately 2 mA. The EA treatment was administered once daily for 30 minutes for 3, 7, or 14 days based on the designated sampling time points. Gait analysis was performed using the Cat Walk XT^TM system. Hematoxylin-eosin (HE) staining was used to observe the morphological changes in the gastrocnemius muscle. Masson staining was applied to evaluate collagen fiber content. Immunofluorescence was used to detect the expression of proliferating cell nuclear antigen (PCNA) in muscle satellite cells. Immunohistochemistry was used to assess the expression levels of CD68 and CD206, markers of macrophages. Serum levels of pro-inflammatory cytokines (TNF-α, IL-1β) and anti-inflammatory cytokines (IL-10, IL-13) were detected using ELISA. RESULTS: Compared with the blank group, the model group showed a significant reduction in average movement speed on days 3 and 7 after modeling (P<0.05), and a decrease in the right hind limb stride length on day 3 (P<0.05). Compared with the model group, the EA group showed increased average movement speed and right hind limb stride length on day 7 (P<0.05). In the blank group, the gastrocnemius muscle on the right side showed uniform and consistent inter-fiber spacing, with neatly and regularly arranged muscle cells. In contrast, the model group exhibited enlarged inter-fiber spacing, edema, and significant infiltration of red blood cells and inflammatory cells, with progressively increasing fibrosis over time. By day 14 after modeling, the EA group showed a return to baseline levels of inflammatory cell infiltration, and the degree of fibrosis was significantly lower than that observed in the model group. Compared with the blank group, the ratio of collagen fibers in the gastrocnemius muscle of the model group increased significantly on days 3, 7, and 14 after modeling (P<0.05). Compared with the model group, the EA group exhibited a lower collagen fiber ratio on days 3, 7, and 14 (P<0.05). Compared with the blank group, PCNA positive expression in the gastrocnemius muscle of the model group was significantly increased on days 3, 7, and 14 after modeling (P<0.05). Compared with the model group, the EA group exhibited significantly higher PCNA positive expression on days 3 and 7 (P<0.05). Compared with the blank group, the model group showed a significant increase in CD68-positive macrophage expression in the gastrocnemius muscle on day 3 after modeling (P<0.05), while CD206-positive macrophage expression increased on days 3, 7, and 14 (P<0.05). Compared with the model group, CD68 expression was significantly lower in the EA group on day 3 (P<0.05), whereas CD206 expression was significantly higher on days 3 and 7 (P<0.05), peaking on day 7 with CD206 expression. Compared with the blank group, serum TNF-α levels were significantly elevated in the model group on days 3 and 7 after modeling (P<0.05), while serum IL-1β levels were increased on days 3, 7, and 14 (P<0.05). Serum IL-10 and IL-13 levels were significantly higher on day 7 after modeling (P<0.05). Compared with the model group, the EA group exhibited lower serum TNF-α level on day 3 (P<0.05) and reduced serum IL-1β levels on days 3 and 7 (P<0.05), while serum IL-10 and IL-13 levels were significantly increased on day 7 (P<0.05). CONCLUSION EA could promote the repair of acute blunt contusion-induced gastrocnemius muscle injury by regulating the proliferation and differentiation of muscle satellite cells. This process is closely related to macrophage polarization.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

BACKGROUND: Telesurgery has the potential to overcome spatial limitations for surgeons, which depends on surgical robot and the quality of network communication. However, the influence of network latency and bandwidth on telesurgery is not well understood. METHODS: A telesurgery system capable of dynamically adjusting image compression ratios in response to bandwidth changes was established between Beijing and Sanya (Hainan province), covering a distance of 3000 km. In total, 108 animal operations, including 12 surgical procedures, were performed. Total latency ranging from 170 ms to 320 ms and bandwidth from 15-20 Mbps to less than 1 Mbps were explored using designed surgical tasks and hemostasis models for renal vein and internal iliac artery rupture bleeding. Network latency, jitter, frame loss, and bit rate code were systemically measured during these operations. National Aeronautics and Space Administration Task Load Index (NASA-TLX) and a self-designed scale measured the workload and subjective perception of surgeons. RESULTS: All 108 animal telesurgeries, conducted from January 2023 to June 2023, were performed effectively over a total duration of 3866 min. The operations were completed with latency up to 320 ms and bandwidths as low as 1-5 Mbps. Hemostasis for vein and artery rupture bleeding models was effectively achieved under these low bandwidth conditions. The NASA-TLX results indicated that latency significantly impacted surgical performance more than bandwidth and image clarity reductions. CONCLUSIONS This telesurgery system demonstrated safety and reliability. A total of 320 ms latency is acceptable for telesurgery operations. Reducing image clarity can effectively mitigate the potential latency increase caused by decreased bandwidth, offering a new method to reduce the impact of latency on telesurgery.

BACKGROUND: Meningeal metastasis (MM) is a form of malignant metastasis where tumor cells spread from the primary site to the pia mater, dura mater, arachnoid, subarachnoid space, and other cerebrospinal fluid compartments. Lung cancer is one of the most common malignant tumor types with MM. MM not only signifies that the lung cancer has progressed to an advanced stage but also leads to a range of severe clinical symptoms due to meningeal involvement. Currently, the risk factors associated with the development of MM are not fully elucidated. The aim of this study was to investigate the risk factors for MM in patients with lung adenocarcinoma (LUAD) who underwent non-surgical interventions, in order to identify LUAD patients at high risk for MM. METHODS: This retrospective study analyzed the clinical data of patients diagnosed with LUAD at the First Affiliated Hospital of Zhengzhou University from January 2020 to July 2024. Missing data were imputed using multiple imputation methods, and risk factors were identified through LASSO, univariate, and multivariate Logistic regression analyses. RESULTS: A total of 170 patients with LUAD were included in this study and divided into two groups: 87 patients with MM and 83 patients without MM. Univariate and multivariate Logistic regression analyses revealed that younger age at diagnosis (P=0.004), presence of the epidermal growth factor receptor (EGFR) L858R gene mutation (P=0.008), and concurrent liver metastasis at baseline (P=0.004) were independent risk factors for developing MM in LUAD patients who did not undergo surgical intervention. Conversely, higher baseline globulin levels (P=0.039) and the presence of the anaplastic lymphoma kinase (ALK) gene mutation (P=0.040) were associated with a reduced risk of MM development. CONCLUSIONS Age at diagnosis, EGFR L858R mutation status, ALK gene mutation status, concurrent liver metastasis, globulin levels at baseline were significantly associated with the risk of developing MM in patients with LUAD patients who did not undergo surgical intervention. For patients diagnosed at a younger age, carrying the EGFR L858R mutation, or presenting with baseline liver metastasis, early implementation of tertiary prevention strategies for MM is crucial. Regular monitoring of MM status should be conducted in these high-risk groups.

ObjectiveTo observe the therapeutic effects of Qishao Huoxue prescription on patients with lumbar disc herniation due to Qi stagnation and blood stasis and the effects of this prescription on hemorheological parameters and serum levels of inflammatory mediators. MethodA total of 86 patients with lumbar disc herniation due to Qi stagnation and blood stasis treated in the Wangjing Hospital of China Academy of Chinese Medical Sciences from January 2023 to February 2024 were selected and assigned according to the random number table into observation and control groups （n=43）. Patients in both groups received lumbar traction treatment. In addition， the observation group was orally treated with Qishao Huoxue prescription and the control group with celebrex for 3 weeks. The visual analogue scale （VAS） score， Oswestry disabilitiy index （ODI） score， 12-item Short-Form Survey （SF-12） score， traditional Chinese medicine （TCM） symptom score， hemorheological parameters ［whole blood high shear viscosity， middle shear viscosity， low shear viscosity， plasma viscosity （PV）， and fibrinogen （FIB）］， and the serum levels of inflammatory mediators ［tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and transforming growth factor-β₁ （TGF-β₁）］ were determined before and after treatment. In addition， the clinical efficacy and adverse reactions were observed and compared between the two groups. ResultAfter treatment， both groups showed declined VAS， ODI， and TCM symptom scores （P<0.05）， increased SF-12 physical component summary （PCS） and mental component summary （MCS） scores （P<0.05）. After treatment， the whole blood high shear viscosity， middle shear viscosity， low shear viscosity， PV， and FIB decreased in the observation group （P<0.05）， while they did not show significant variations in the control group. After treatment， both groups of patients showed reductions in TNF-α， IL-6， and IL-1β levels and an elevation in the TGF-β₁ level （P<0.05）. Compared with the control group after treatment， the observation group showed decreases in VAS， ODI， TCM symptom scores and main symptom scores （P<0.05）， no significant differences in the secondary symptom scores， increased PCS and MCS scores （P<0.05）. The observation group outperformed the control group in terms of recovering whole blood high shear viscosity， middle shear viscosity， low shear viscosity， PV， FIB， TNF-α， IL-6， IL-1β， and TGF-β₁ （P<0.05）. The total response rate in the observation group was 97.5% （40/41）， which was higher than that （88.1%， 37/42） in the control group （P<0.05）. No serious adverse reaction was observed in the two groups during the observation period. One case in the observation group showed subcutaneous bruising on the lower limbs， which gradually disappeared after withdrawal. ConclusionQishao Huoxue prescription demonstrated definite effect in treating lumbar disc herniation due to qi stagnation and blood stasis by recovering hemorheological parameters and inhibiting the expression of inflammatory mediators in the serum without inducing adverse reactions. It is worth applying in clinical practice.

Objective:To compare the characteristics of cerebrospinal fluid (CSF) oligoclonal band electrophoresis examination results between patients with multiple sclerosis (MS) and Guillain-Barré syndrome (GBS), and to provide a basis for the differential diagnosis of the two types of neurological demyelinating diseases.Methods:Case analysis.The retrospective study method was used, and the patients who visited Beijing Tiantan Hospital, Capital Medical University from January 2020 to August 2023 were selected as the research subjects, including 70 MS patients[19 males and 51 females, aged 34 (28, 44) years] and 70 GBS patients [44 males and 26 females, aged 50 (36, 61) years]. The oligoclonal band electrophoresis and immunoglobulin G(IgG) index (IgG I) were performed on the clinical specimens from MS and GBS patients, and CSF routine, CSF biochemistry (glucose, chloride, protein), lactate, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α), antibodies to herpes simplex virus (HSV), cytomegalovirus (CMV), rubella virus (RV), toxoplasma gondii (TOX), Epstein-Barr virus (EBV), and coxsackievirus were detected simultaneously. The enumeration data were treated with the chi-square test. The measurement data didn′t accord with normal distribution, and were treated with the Mann-Whitney U test. Results:The positive rate of oligoclonal band (OCB) electrophoresis in MS and GBS patients were 80.00% (56/70) and 4.29% (3/70), respectively. The positive rate in MS patients was significantly higher than that in GBS patients (χ 2=82.289, P<0.001). The white blood cells count [5.50 (3.00, 11.00)/μl] and the level of chlorine [127 (125, 128) mmol/L] in CSF of MS patients was higher than that of GBS patients [3.50(2.00, 7.00)/μl, 126(124, 128) mmol/L] ( U=-2.245, P<0.05; U=-2.028, P<0.05), while the levels of CSF protein [33.40(27.61, 39.17)mg/L], glucose [3.59(3.36, 3.88) mmol/L], and lactate [1.55(1.40, 1.73) mmol/L] of MS patients were lower than those of GBS patients [6.71(43.78, 138.30) mg/L, 3.97(3.55, 4.54) mmol/L, 1.80(1.60, 2.00) mmol/L]( U=-6.747, P<0.001; U=-3.651, P<0.001; U=-4.531, P<0.001). The levels of IL-6 [3.36(2.34, 5.02) pg/ml], IL-8 [55.40(46.75, 66.40) pg/ml], and TNF-α [5.63(4.25, 6.63) pg/ml] in CSF of MS patients were lower than those of GBS patients [6.12(3.61, 11.73) pg/ml, 120.00(74.90, 187.80) pg/ml, 6.57(5.25, 8.03) pg/ml]( U=-3.463, P<0.05; U=-5.225, P<0.001; U=-2.785, P<0.05). The positive rates of CMV IgG, TOX IgG, and EBVCA IgG in CSF of MS patients were 36.36% (24/66), 0 and 0, respectively,and the positive rates of those of GBS patients were 85.71% (54/63), 30.16% (19/63), and 19.05% (12/63), respectively. The positive rates of CMV IgG, TOX IgG, and EBVCA IgG in CSF of MS patients were significantly lower than those of GBS patients (χ 2=32.839, P<0.001; χ 2=23.343, P<0.001; χ 2=13.861, P<0.001). Conclusions:The MS patients mainly showed the higher positive rates of OCB. The GBS patients showed elevated CSF protein levels but no significant increase in white blood cell count, namely albuminocytologic dissociation in CSF. Meanwhile, the GBS patients showed elevated levels of intrathecal immunity and inflammation indicators, and a higher positive rate of pathogen antibodies.

Objective:Laboratory evaluation of the relationship between cerebrospinal fluid and plasma indicators and intrathecal immunoglobulin G(IgG) synthesis in patients with neurological diseases, and establishment of a new diagnostic method for intrathecal IgG synthesis.Methods:This study retrospectively analyzed the content of IgG in cerebrospinal fluid samples and blood albumin in blood samples, and other test results of 410 patients with neurological diseases who visited Beijing Tiantan Hospital from 2019 to 2022. According to the results of oligoclonal bands in cerebrospinal fluid, patients were divided into intrathecal IgG synthesis group and non-intrathecal IgG synthesis group. The Mann Whitney U test was used for inter group comparison, and a bilateral test with P<0.05 indicates a statistically significant difference. Include indicators with differences between groups in logistic regression analysis, construct a predictive model, and compare it with the established quantitative formula IgG index. Results:There were significant differences in 10 indicators, including cerebrospinal fluid leukocyte count and 24-hour intrathecal IgG synthesis rate, between the intrathecal IgG synthesis group and the non-intrathecal IgG synthesis group, with P<0.05. The area under the curve (AUC) of intrathecal IgG synthesis was higher than the IgG index (AUC=0.920, 0.809, Z=31.178, P<0.001), the sensitivity was higher than the IgG index (0.825, 0.618), and the specificity was lower than the IgG index (0.876, 0.908). Conclusion:The combination of 10 indicators such as cerebrospinal fluid white blood cell count and 24-hour intrathecal IgG synthesis rate can improve the diagnostic efficacy and sensitivity of intrathecal IgG synthesis.

ObjectiveTo evaluate the clinical effectiveness and safety of acupuncture with manipulation for lumbar disc herniation in remission period. MethodsOne hundred and four patients with lumbar disc herniation in remission were randomly divided into a treatment group and a control group， with 52 cases in each group. Treatment group applied acupuncture with manipulation of pointing， pulling， and shaking. Acupoints were selected as lumbar Jiaji （EX-B2， bilateral）， Ashi point， Shenshu （BL 23， bilateral）， Huantiao （GB 30， bilateral）， Weizhong （BL 40， opposite side of the affected area）， Chengshan （BL 57， opposite side of the affected area）. The control group applied lumbar traction plus acupoint ultrasonic pulse penetration therapy （acupoints selection same as the treatment group）； 20 minutes each time， 3 times a week， a total of 3 weeks for both groups. The primary outcome was the improvement rate of lumbar disc herniation symptoms and signs， which was calculated at 1 week of treatment， 3 weeks of treatment， 1 month follow-up， and 3 months follow-up， respectively； the secondary outcome were the Japanese Orthopaedic Association （JOA） scores， Visual Analogue Scale （VAS） scores， and Oswestry Disability Index （ODI） scores （including ODI total scores， sitting scores and standing scores）， which were evaluated before treatment， 1 week of treatment， 3 weeks of treatment， 1 month follow-up， and 3 months follow-up； clinical effectiveness was assessed at 3 months follow-up； and the occurrence of adverse events in the participants， as well as blood routine， urine routine， stool routine， and electrocardiograms before and after the treatment were recorded to evaluate safety. ResultsTwo patients from each group fell out， and 50 patients of each group were included in the outcome analysis ultimately. The scores of lumbar disc herniation symptoms and signs improved more in the treatment group than in the control group at 1 week of treatment， 3 weeks of treatment， 1 month follow-up and 3 months follow-up （P＜0.01）. The JOA scores of participants in both groups at 1 week of treatment， 3 weeks of treatment， 1 month follow-up and 3 months follow-up were higher than those before treatment in the same group， and the VAS scores， ODI total scores， ODI sitting scores and standing scores were significantly lower than those before treatment in the same group （P＜0.05）， and the JOA scores of patients in the treatment group were higher than those of the control group at all time points， and the VAS scores， ODI total scores， ODI sitting scores and standing score were lower than those of the control group （P＜0.05）. At the 3 months follow-up， the excellent rate of the treatment group was 70.00% （35/50） better than that of the control group， which was 50.00% （25/50） （P＜0.05）. There were no abnormalities in blood， urine， stool routines and electrocardiograms before and after treatment in both groups， and no adverse events occurred. ConclusionAcupuncture with manipulation of pointing， pulling， and shaking for treating patients with lumbar disc herniation in remission has a better safety on pain relief and improving quality of life， and the effectiveness is better than lumbar traction plus acupoint ultrasonic pulse penetration therapy.
