ObjectiveMicrotube associated protein-2 (MAP-2), alpha-tubulin (α-tubulin), and synaptophysin (SYP) are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein (α-Syn) and its oligomers, MAP-2, α-tubulin, and SYP of patients with liver and kidney deficiency of Parkinson's disease (PD), analyzed their correlation, and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group (30 cases) and a control group (30 cases). Both groups were treated on the basis of PD medicine, and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score, TCM syndrome score, and expression of serum α-Syn and its oligomers, MAP-2, α-tubulin, and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment, the TCM syndrome score, UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ score of the treatment group were significantly decreased (P<0.05, P<0.01). The UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment (P<0.05). After treatment, the total effective rate of the control group was 63.3% (19/30), and that of the treatment group was 86.7% (26/30). The clinical effect of the observation group was better than the control group (Z=-2.03, P<0.05). The total effective rate of the observation group was better than that of the control group, and the difference was statistically significant (χ2=5.136, P<0.05). After treatment, the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased (P<0.05, P<0.01). The levels of serum α-Syn and its oligomers, as well as α-tubulin in the treatment group, were significantly decreased compared with those in the control group after treatment (P<0.05, P<0.01). Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD (P<0.05, P<0.01) but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin (P<0.05, P<0.01) but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 (P<0.05). ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective:To compare the clinical efficacy and safety of bronchial artery chemoembolization (BACE) combined with anlotinib (BACE+A) versus BACE alone in patients with stage III-IV non-small cell lung cancer (NSCLC).Methods:A total of 94 patients with advanced NSCLC treated at six interventional centers between November 2020 and November 2021 were retrospectively enrolled. Patients were divided into the BACE+A group ( n=46) and the BACE alone group ( n=48) based on treatment regimen. Baseline and perioperative clinical data were collected and compared between the two groups. Treatment response was evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) at 1, 6, and 12 months after the first BACE procedure. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were recorded. Kaplan-Meier survival curves were plotted to compare median OS and PFS between groups. Cox proportional hazards regression analysis was used to identify factors influencing OS and PFS. Results:The Kaplan-Meier analysis showed that the median OS was significantly longer in the BACE+A group (18.8 months, 95% CI 16.3-21.3) than in the BACE group (13.4 months, 95% CI 11.6-15.2) ( P=0.001). The median PFS was also significantly longer in the BACE+A group (9.0 months, 95% CI 7.3-10.7) compared to the BACE group (6.1 months, 95% CI 4.9-7.3) ( P=0.001). At 6 and 12 months post-first BACE, the ORR (43.5%, 40.0%) and DCR (89.1%, 83.3%) were significantly higher in the BACE+A group than in the BACE group (ORR: 20.8%, 14.8%; DCR: 66.7%, 59.3%) (all P<0.05). Multivariate Cox regression identified treatment with BACE+A ( HR=0.42, 95% CI 0.27-0.72, P=0.002), tumor stage ( HR=1.80, 95% CI 1.05-3.07, P=0.031), presence of pre-existing complications requiring intervention ( HR=2.72, 95% CI 1.65-4.50, P<0.001), and >2 BACE procedures ( HR=0.32, 95% CI 0.15-0.68, P=0.003) as independent factors influencing OS. Treatment with BACE+A ( HR=0.49, 95% CI 0.32-0.76, P=0.001), tumor stage ( HR=1.72, 95% CI 1.07-2.77, P=0.025), multi-arterial tumor blood supply ( HR=2.76, 95% CI 1.76-4.31, P<0.001), and>2 BACE procedures ( HR=0.40, 95% CI 0.22-0.71, P=0.002) were independent factors influencing PFS. There was no significant difference in BACE-related adverse events between the two groups (all P>0.05). Hypertension, fatigue, hand-foot syndrome, and anorexia were common anlotinib-specific adverse reactions in the combination group, but no grade 4 or higher adverse reactions were observed. Conclusions:BACE combined with anlotinib demonstrates superior efficacy compared to BACE alone in treating advanced NSCLC, significantly prolonging OS and PFS. The safety profile is manageable, with adverse events remaining within tolerable limits.

Objective:To analyze the epidemiological and clinical characteristics of respiratory pathogens in China.Methods:This study was a cross-sectional study, which encompassed 19 core units of the clinical pathogen network and established a three-tiered clinical pathogen surveillance system. Thirty respiratory samples were collected every two weeks from various units from January to December 2024, and the clinical and pathogen diagnostic information were gathered. A total of 11 864 samples were tested using this system. The tier-1 clinical pathogen surveillance system covered influenza A virus (Flu-A), influenza B virus (Flu-B), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The tier-2 clinical pathogen surveillance system focused on 18 key respiratory pathogens. The tier-3 clinical pathogen surveillance system further clarified whether any emerging infectious diseases had occurred.Results:The tier-1 clinical pathogen surveillance system showed Flu-A predominated in December, Flu-B predominated in January, SARS-CoV-2 peaked in March and August, whereas RSV circulated sporadically throughout the year. Geographic trends were broadly consistent across the seven major regions, although Flu-A detection in December was notably higher in Northeast China (48.1%(111/231)) and East China (36.2%(148/409)), and RSV detection was concentrated in the Northwest and South China from January to March. Data from the tier-2 clinical pathogen surveillance system indicated that Streptococcus pneumoniae, Mycoplasma pneumoniae, rhinovirus, and adenovirus were detected year-round, of these, Streptococcus pneumoniae and rhinovirus showed elevated positive detection rates from August to September, while adenovirus peaked in January. Legionella pneumophila was not detected throughout the year, and other pathogens fluctuated throughout the year without a consistent pattern. The predominant etiologic agents of pediatric pneumonia were Mycoplasma pneumoniae (35.0%(105/300)), rhinovirus (25.7%(77/300)), and adenovirus (17.3%(52/300)), whereas adult pneumonia was mainly caused by Streptococcus pneumoniae (10.5%(29/277)), Staphylococcus aureus (6.9%(19/277)), Mycoplasma pneumoniae (6.9%(19/277)), and Flu-A (6.1%(17/277)). The tier-3 clinical pathogen surveillance system did not identify any emerging respiratory pathogens. Conclusion:Respiratory pathogens in China in 2024 exhibit distinct temporal and spatial distribution patterns and vary among different populations.

Objective:To compare the cost-effectiveness of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) versus percutaneous endoscopic discectomy (PTED) for the treatment of single-segment lumbar disc herniation (LDH). Methods:This study is a retrospective analysis that included patients diagnosed and treated with either MIS-TLIF or PTED for single-segment LDH at Hefei First People's Hospital from January to December 2022. The study comprised 35 patients in the MIS-TLIF group and 35 patients in the PTED group. Total medical costs, surgery duration, blood loss, time to catheter removal, Visual Analog Scale scores before surgery, and at 3 and 12 months post-surgery, along with the Oswestry Disability Index, were recorded for each group. The cost-effectiveness ratio was compared between the two groups.Results:A total of 70 patients were included, including 35 patients in the MIS-TLIF group and 35 patients in the PTED group. There was no significant difference in general data between the two groups (all P >0.05). The differences in Visual Analog Scale and Oswestry Disability Index scores between the two groups, as well as within each group before surgery, and at 3 and 12 months post-surgery, were not statistically significant (all P > 0.05). The surgery duration for the PTED group [(112.94 ± 53.17) minutes] was significantly shorter than that of the MIS-TLIF group [(210.14 ± 25.68) minutes, Z = 2.21, P < 0.05]. However, the success rate for the PTED group [94.29% (33/35)] was not significantly different from that of the MIS-TLIF group [91.43% (32/35), Z = 0.46, P > 0.05]. The cost-effectiveness ratio for the PTED group was 239.56, while the cost-effectiveness ratio for the MIS-TLIF group was 377.69. Conclusions:PTED offers greater economic advantages in the treatment of single-segment LDH, particularly in terms of reduced blood loss and shorter surgery duration compared with MIS-TLIF. The choice of surgical approach should be made according to clinical requirements.

Background and Aims:Cholangiocarcinoma,a rare malignant tumor,is difficult to diagnose and often detected at an advanced stage,limiting treatment options to palliative care.Conventional chemotherapy drugs have poor efficacy against cholangiocarcinoma,making the search for new treatments critical.This study was conducted to investigate the effects of Huai'erjunzhi on the malignant biological behavior of human cholangiocarcinoma cells and its relationship with the TGF-β/Smad pathway,aiming to provide a theoretical basis for the use of Huai'erjunzhi in cholangiocarcinoma treatment. Methods:Human normal liver cells(L-02)and human cholangiocarcinoma cells(HuCCT1)were incubated with different concentrations of Huai'erjunzhi for various durations.Cell proliferation was assessed,and the half-maximal inhibitory concentration(IC50)was calculated.HuCCT1 cells were divided into a negative control group(no intervention),a positive control group(15 mg/L cisplatin),and different Huai'erjunzhi intervention groups(1/5 IC50,2/5 IC50,and IC50 based on preliminary experimental results).Scratch and Transwell assays were used to measure cell migration and invasion,while Western blot was employed to detect the expression of proteins related to the TGF-β/Smad pathway in HuCCT1 cells. Results:Only high concentrations of Huai'erjunzhi(>312.5 mg/L)significantly inhibited the proliferation of L-02 cells.Huai'erjunzhi significantly inhibited the proliferation of HuCCT1 cells at concentrations above 5 mg/L in a concentration-dependent manner(all P<0.05),with IC50 values of 138.52 mg/L at 24 h,99.41 mg/L at 48 h,and 113.52 mg/L at 72 h.Compared with the negative control group,the positive control group and the three Huai'erjunzhi intervention groups(20,40,and 100 mg/L)exhibited reduced migration distance,decreased invasive cell numbers,lower expression of TGF-β1,Smad2,Smad3,Smad4,N-cadherin,Snail,and Slug,and increased expression of E-cadherin(all P<0.05).Compared with the positive control group,these changes in the Huai'erjunzhi groups were less pronounced but showed a clear concentration-dependent relationship(all P<0.05). Conclusion:Huai'erjunzhi can potentially inhibit the malignant biological behavior of HuCCT1 cells by inhibiting the TGF-β/Smad pathway.
