Objective:To observe the clinical effect of computed tomography(CT)-guided hematoma puncture drainage surgery combined with high-dose(≥50 000 U)urokinase in treating hypertensive intracerebral hemorrhage.Methods:The case data of a total of 90 patients with hypertensive intracerebral hemorrhage who underwent treatment in Zhangjiakou First Hospital from January 2022 to January 2023 were retrospectively selected as the study subjects.They were divided into a control group and an observation group using the average method,with 45 cases in each group.The conventional group received CT-guided hematoma puncture drainage surgery combined with conventional dose urokinase(20 000 U),while the observation group received CT-guided hematoma puncture drainage surgery combined with high-dose urokinase(50 000 U),with a 6-month follow-up for all patients.The changes of hematoma volume,length of hospital stay,levels of inflammatory indicators,the levels of hemodynamics,clinical efficacy,and incidence of postoperative complications after treatment between two groups were analyzed and compared.Results:After treatment,the hematoma volume at the 1st day[(34.64±5.53)mm3]and the 7th day[(34.64±5.53)mm3]post surgery of observation group were significantly lower than those[(44.57±6.85)mm3 and(16.64±3.24)mm3]of conventional group,and the differences of them between the two groups were statistically significant(t=7.567,10.570,P<0.05),respectively.The length of hospital stay of observation group[(16.86±6.63)d]was significantly lower than that of the control group[(23.47±10.34)d](t=3.610,P<0.05).The levels of matrix metalloproteinase-9(MMP-9),interleukin-6(IL-6),C-reactive protein(CRP),tumor necrosis factor-α(TNF-α)at 7th days post surgery of observation group were significantly lower than those of conventional group,and the differences of them between the two groups were statistically significant(t=5.826,10.202,7.661,2.724,P<0.05),respectively.The blood flow levels of middle cerebral artery(MCA),anterior cerebral artery(ACA),and posterior cerebral artery(PCA)after surgery in observation group were significantly higher than those in conventional group(t=2.833,3.329,3.973,P<0.05),respectively.The effective rate of treatment in observation group(95.56%)was significantly higher than that in conventional group(80.00%),and the difference was significant(x2=5.075,P<0.05).There was no significant difference in the incidence of postoperative complications between the two groups(P>0.05).Conclusion:CT-guided hematoma puncture drainage surgery combined with high-dose urokinase can significantly increase the dissolution rate of hematoma,and reduce the body's inflammatory response,and improve cerebral hemodynamic indicators,and effectively enhance clinical efficacy in treating hypertensive intracerebral hemorrhage,which have better treatment safety.

Objective To explore the correlation between Toll-like receptor(TLR)and nuclear factor-KB(NF-κB)levels in monocytes and type 2 diabetic autonomic neuropathy(T2DAN).Methods A total of 112 patients with type 2 diabetes mellitus(T2DM)admitted to the Puyang People's Hospital from April 2021 to December 2022 were selected as the observation group,and 50 healthy volunteers who underwent physical examination in the hospital during the same period were selected as the control group.Reverse transcription polymerase chain reaction(RT-PCR)was used to detect plasma TLR2,TLR4 and NF-κB levels in monocytes of patients in the two groups.According to the presence or absence of autonomic neuropathy,patients in the observation group were divided into the autonomic neuropathy group(n=46)and the non-autonomic neuropa-thy group(n=66),and clinical data of patients in these two groups were compared.Multivariate logistic regression analysis was used on indicators with statistically significant differences to determine the risk factors for T2DAN,and Spearman correlation analysis was used to evaluate the correlation between TLR2,TLR4 and NF-κB levels and T2DAN.Results The TLR2,TLR4 and NF-κB levels in monocytes of patients in the observation group were higher than those in the control group(P＜0.05).Univariate analysis showed that there were significant differences in age,monocyte/high-density lipoprotein ratio(MHR),and levels of cystatin C,TLR2,TLR4 and NF-κB between the autonomic neuropathy group and the non-autonomic neuropathy group(P＜0.05).Multivariate logistic regression analysis showed that MHR,TLR2,TLR4 and NF-κB levels were risk factors for autonomic neuropathy in T2DM patients(P＜0.05).Spearman correlation analysis showed that TLR2,TLR4 and NF-κB levels were positively correlated with T2 DAN(r=0.825,0.822,0.819;P＜0.05).Conclusion The expressions of TLR2,TLR4 and NF-κB are up-regulated in T2DM patients,and the expression levels of TLR2,TLR4 and NF-κB are correlated with autonomic neuropathy in T2DM patients.

As a real-time,rapid and non-invasive method for monitoring the occurrence and development of various diseases and evaluating the health status of the body,breath detection has attracted wide attention in the application of early lung cancer screening.However,there is significant variability in the reported specific biomarkers of lung cancer,making it difficult to reach a unified consensus.Meanwhile,the pathways for the generation of volatile organic compounds(VOCs)in exhaled breath of lung cancer patients remain unclear,and further research on the detailed metabolic mechanisms is required.Therefore,this review comprehensively summarizes the VOCs detected in the exhaled breath of lung cancer patients from relevant literature in the past five years,deeply analyzes the production mechanism of these VOCs and the internal correlation with the disease,and evaluates the performance of the lung cancer prediction models constructed based on these VOCs,in order to provide reference for clinical and subsequent researches.

ObjectiveOptimize the latex perfusion technique and apply it to the construction of a murine craniofacial venous vascular model.Methods A total of nine 8-week-old male C57BL/6 mice weighing (25.0±1.3) g were randomly divided into three groups: 60% latex physiological saline group, 60% latex heparin group, and 30% latex heparin group. After completion of the perfusion, the specimens were immersed in 4 °C formalin fixative for 24 h, followed by dissection, observation, and measurement of the extracranial blood vessel diameters. Results After 200 μL latex perfusion solution was injected into the external jugular vein, the supraorbital vein, infraorbital vein, temporal vein, retrofacial vein, masseter vein and external jugular vein were perfused in each group.After comparing the perfusion degree of the distal branches of blood vessels, sublingual vein and tip venule, it was found that the 30% latex heparin group had the best perfusion effect, followed by the 60% latex heparin group, and the 60% latex saline group had the worst perfusion effect.ConclusionThe optimized latex perfusion technique can effectively infuse the veins in the head and face of mice, and this technique can provide a good reference for the study of the direction and morphology of facial veins in mice.

Objective:To establish the quality evaluation method of Perillae caulis formula granules based on the three kind of quality indexes of standard decoction. Methods:Eighteen batches of Perillae caulis were collected from different habitats according to different technical requirements, eighteen batches of standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The content of Caffeic acid and Rosmarinic acid were determined and calculated by Ultra High Performance Liquid Chromatography (UPLC). Then the fingerprints of standard decoction of and formula granules of Perillae caulis were established by UPLC . The similarity values of fingerprints between formula granules and standard decoction were calculated. Results:The average paste-forming rate of standard decoction was (7.16±1.97)%. The paste-forming rates of three batches of formula granules were 5.52%, 5.25% and 5.34%, respectively. The average content of Caffeic acid and Rosmarinic acid in standard decoction was (12.06±3.37)mg/g. The contents of three batches of formula granules were 5.52, 5.82, 5.77 mg/g, respectively. Seven common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, three of which were identified as Caffeic acid, N-Feruloyl Octopus amine and Rosmarinic acid by comparison of reference substance. The fingerprints similarity of Perillae caulis dispensing granules and standard decoction were 1.000, 0.995 and 0.997, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method can provide basis for the establishment of quality standard of Perillae caulis dispensing granules.
