ObjectiveTo assess the efficacy and safety of the Qi-regulating and phlegm-removing method（Liu Junzitang Combined with Linggang Wuwei Jiangxintang） for treating acute exacerbations of chronic obstructive pulmonary disease （AECOPD） with increased eosinophils （EOS）. MethodsSixty-eight AECOPD patients with increased EOS who were hospitalized in the Department of Pulmonary Diseases of Jinhua Traditional Chinese Medicine Hospital from April 2023 to April 2024 were recruited and randomly assigned to an experimental group （EG） or a control group （CG）. Both groups received conventional Western medicine， with the EG additionally receiving Liujunzitang and Linggan Wuwei Jiangxintang. The therapeutic efficacy indicators were measured after the treatment. The main therapeutic efficacy indicators included partial pressure of oxygen （PaO₂） and partial pressure of carbon dioxide （PaCO₂）. The secondary efficacy indicators included the TCM symptom scores， the COPD Assessment Test （CAT） score， the Modified Medical Research Council （mMRC） Dyspnea Scale score， and the length of hospital stay. The indicators were measured at baseline and on days 3 and 7 of intervention. The safety was evaluated based on the adverse events. ResultsBaseline characteristics were not statistically different between the two groups. Compared with CG， EG showed no significant difference in PaO₂ （P=0.773）， PaCO₂ （P=0.632） and or CAT score （P=0.336） at on day 3 but better PaO₂ （P=0.004）， PaCO₂ （P=0.008）， and CAT score （P=0.013） were significantly better at on day 7. Compared with CGAfter treatment， EG had lower TCM syndrome scores of than CG EG on day 3 （P=0.005） and day 7 were significantly decreased （P0.001）. There was no significant difference in mMRC score between the two groups on day 3 （P=0.514） and day 7 （P=0.176） as wasor the length of hospital stay （P=0.915）. The generalized linear mixed model （GLMM） showed that compared with CG， EG had significant improvements over time in PaO₂， PaCO₂， TCM syndrome symptom scores， CAT score， and mMRC score. ConclusionRegulating qi Qi and removing phlegm combined with conventional Western medicine can significantly alleviateimprove the clinical symptoms and improve the lung function of AECOPD patients with increased EOS increased AECOPDwhich has and demonstrates good safety.

Objective To construct glucose oxidase（GOx）–loaded nanogels （GONGs）, optimize their formulation, and evaluate their capacity to inhibit the Warburg effect in glioma cells. Methods A responsive polymer （HAM） was synthesized and used to self-assemble GONGs, which were then characterized. Encapsulation efficiency and drug loading were determined using fluorescence spectrophotometry. Biocompatibility was tested by measuring cytotoxicity and hemolytic activity. Western blotting was used to evaluate the effects of GONGs on the expression of proteins associated with the Warburg phenotype and oxidative damage in glioma cells. Results GONGs prepared at a drug–to–polymer ratio of 1∶10 exhibited a particle size of 140.3 nm and a zeta potential of −27.2 mV. Compared with free GOx, GONGs markedly reduced cytotoxicity, increased the IC₅₀ in hUVEC cells from 2.150 nmol/L to 74.86 nmol/L, and significantly decreased hemolysis. At a GOx concentration of 2 nmol/L, GONGs effectively downregulated glycolysis-related proteins, such as HK2 and LDHA, and inhibited glutamine metabolism in glioma cells. Conclusion GONGs exhibited high GOx loading capacity, significantly reduced GOx-induced cytotoxicity, inhibited the Warburg effect in glioma cells and induced oxidative damage.

Objective To analyze the clinical characteristics and risk factors of noninfectious fever after endovascular repair of aortic dilatation diseases, and to explore management strategies. Methods A retrospective analysis was conducted on the clinical data of patients who underwent endovascular aortic repair for aortic dilatation diseases from January 2021 to October 2023. Based on inclusion and exclusion criteria, the enrolled patients were divided into a febrile group and an afebrile group according to the presence of postoperative fever. Clinical data, including demographics and surgical details, were compared between the two groups. Multivariate logistic regression analysis was performed on indicators with P≤0.05 in the univariate analysis, and receiver operating characteristic (ROC) curves were generated to analyze the predictive value of risk factors for postoperative noninfectious fever. Results A total of 305 patients were included in the final analysis. Postoperative noninfectious fever occurred in 75.08% (229/305) of the patients, with 98.25% of cases occurring within the first two postoperative days. The febrile group (n=229) had a median age of 65.0 (IQR: 53.0, 73.0) years with 83.4% males, while the afebrile group (n=76) had a median age of 71.0 (IQR: 65.0, 76.7) years with 84.2% males. Univariate analysis showed that the age, prevalence of coronary heart disease, preoperative statin use, and prevalence of aortic aneurysm were significantly lower in the febrile group compared to the afebrile group. Logistic regression analysis indicated that age, surgical site, disease type, preoperative elevated body temperature, and stent type were significantly associated with noninfectious fever, while preoperative statin use was negatively correlated. ROC curve analysis demonstrated that age, surgical site, preoperative elevated body temperature, and stent type had significant predictive value for postoperative noninfectious fever (P<0.01). Conclusion Noninfectious fever is highly prevalent following aortic repair. The relationship between fever and infection should be comprehensively evaluated based on risk factors and changes in the patient's condition to promote the rational use of antibiotics.

Based on the theory of "spleen functions as wei qi"， this paper believes that the disease mechanism of allergic rhinitis （AR） in children is the nasal dysfunction caused by the loss of spleen's wei qi. The root cause of AR is the failure of splenic transportation as well as its inability to properly distribute nutrients. The inducement of AR is the invasion of pathogenic qi coupled with insecurity of the wei exterior. The key to AR recurrence lies in the deficiency of healthy qi and lingering of pathogenic qi， with pathogenic qi lodging inside the body. The treatment should adhere to the principle of helping the spleen restore wei qi. During the acute phase， the treatment should dispel wind， conso-lidate the wei qi， and relieve stuffy orifices， and the modified Qufeng Tongqiao Decoction （祛风通窍汤） is used. During the remission phase， the treatment should fortify the spleen， raise the clear， and harmonize the wei qi， and the modified Yuhan Decoction （御寒汤） is applied. During the recovery phase， the treatment should reinforce the healthy qi， consolidate the constitution， and strengthen the wei qi， and the modified Huangqi Jianzhong Decoction （黄芪建中汤） is employed.

ObjectiveTo evaluate the effects of Shenling Guben Granules on quality of life and immune function in patients with HIV classified as immunological non-responders （INRs）. MethodsA prospective， multicenter， randomized， double-blind， controlled trial was conducted from August 21， 2018， to January 6， 2021， across eight hospitals in China. A total of 300 INR patients， diagnosed with spleen-kidney yang deficiency or lung-spleen Qi deficiency syndromes， were enrolled and randomly assigned to either the observation group or the control group， with 150 patients in each group. The control group received antiretroviral therapy （ART） combined with placebo， while the observation group received ART combined with Shenling Guben Granules. After 72 consecutive weeks of treatment， the World Health Organization Quality of Life for HIV brief version （WHOQOL-HIV BREF） was used to assess quality of life before and after treatment in both groups. Immune indicators （CD4⁺ and CD8⁺ T cell counts）， complete blood count， liver and renal function， and adverse events during treatment were also evaluated to assess safety. ResultsA total of 279 patients were included in the final analysis （140 in the observation group and 139 in the control group）. After treatment， CD4⁺ T cell counts in the observation group increased significantly compared to baseline （P< 0.05）， whereas the control group showed an upward trend without statistical significance. Compared with the control group after treatment， the observation group showed a significantly greater increase in CD4⁺ levels （P<0.05）. There were no significant differences in the total score or domain scores of quality of life （physical， psychological， independence， social relationships， environment， and spirituality）， or in CD8⁺ T cell counts， before and after treatment in either group. The incidence of adverse events during treatment was 10% （14/140） in the observation group and 10.07% （14/139） in the control group， with no statistically significant difference between the two groups. ConclusionAlthough Shenling Guben Granules did not significantly improve quality of life in INR patients， they significantly increased CD4⁺ cell counts and demonstrated good safety， providing scientific evidence to support their use as a treatment option for INR patients.

AIM: To compare the agreement between the ARK Biometer Combo and OA 2000 in patients wearing orthokeratology lenses.METHODS: A prospective study. A total of 148 patients(148 eyes)who were wearing orthokeratology lenses and returned for follow-up at the Shanghai Eye Disease Prevention and Treatment Center from August to September 2024 were included. Biometric measurements were performed using both the ARK Biometer Combo and OA 2000. Parameters including axial length(AL), corneal central thickness(CCT), anterior chamber depth(ACD), lens thickness(LT), corneal curvature(Kf and Ks), astigmatism(AST), white-to-white corneal diameter(WTW)and pupil diameter(PD)were obtained. Differences in measurement parameters between the two biometers were compared, and agreement was assessed.RESULTS: There were no statistically significant differences in the measurements of Kf, Ks and AST between the two biometers(P>0.05). Statistically significant differences were found in the measurements of AL, CCT, ACD, LT, WTW and PD(t=2.559, P=0.012; t=16.771, P<0.0001; t=4.749, P<0.0001; t=-15.212, P<0.0001; t=-14.915, P<0.0001; t=-2.402, P=0.018). ICC ranged from 0.615 to 0.999. Bland-Altman analysis showed that the maximum absolute values of the 95% limits of agreement(LoA)of AL, CCT, ACD, LT, Kf, Ks, AST, WTW and PD were 0.07 mm, 35.07 μm, 0.07 mm, 0.12 mm, 0.66 D, 1.14 D, 1.00 D, 0.76 mm, and 0.98 mm, respectively.CONCLUSION: In orthokeratology patients, the ARK Biometer Combo and OA 2000 showed good agreement in measuring AL, CCT, ACD, Kf and LT, and can be used interchangeably.
