In order to construct a novel multifunctional targeting nano-carrier based on pH-redox characteristics of tumor microenvironment,ketone bonds and disulfide bonds were bonded to the oligomeric hyaluronic acid (oHA) being sensitive to pH and the reduction environment.The chemical structure of oligomeric hyaluronic acid-8-mercaptomenthone 1,2-glycerolketal (oHMST) was characterized by 1H NMR,IR and ESI-MS.Curcuminloaded micelles were prepared by dialysis.The single factor investigation was carried out on the dosage form.Some properties,including particle size zeta potential,the morphology of micelles,and pH-sensitivity were studied.The materials were synthesized successfully.The micelles were spheric with a diameter of about 100 nm.The Zeta potential of the micelles was-(21.97 ± 1.08) mV.The in vitro test showed that oHMST carriers have good pH-sensitivity and redox-sensitivity.

Objective:To analyze the effect of donepezil hydrochloride combined with memantine on cognitive function in patients with Alzheimer's disease (AD).Methods:A randomized controlled trial was conducted among 90 patients with AD who were treated at the Zaozhuang Mental Health Center from January 2021 to March 2023. The patients were divided into a donepezil group and a combination group using a random number table grouping method, with 45 patients in each group. The donepezil hydrochloride group received only oral administration of donepezil hydrochloride tablets, while the combination group received oral administration of both donepezil hydrochloride tablets and memantine tablets. The two groups were continuously treated for 12 weeks. Before and after treatment, the Activities of Daily Living scale (ADL) score, the Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD) score, the Mini-Mental State Scale (MMSE) score, and biochemical indicators (homocysteine, neuron-specific enolase, and S100 β) were compared between the two groups. Adverse drug reactions were observed in each group.Results:After treatment, the ADL, BEHAVE-AD, and MMSE scores in the combination group were (78.9 ± 6.1) points, (5.2 ± 0.5) points, and (22.8 ± 2.2) points, respectively, and they were (65.2 ± 5.9) points, (9.6 ± 0.9) points, and (19.4 ± 2.4) points, respectively, in the donepezil hydrochloride group. The ADL and MMSE scores in the combination group were significantly higher than those in the donepezil hydrochloride group ( t = 10.83, 7.01, both P < 0.001). The BEHAVE-AD score in the combination group was significantly lower than that in the donepezil hydrochloride group ( t = -28.67, P < 0.001). After treatment, serum levels of homocysteine, neuron-specific enolase, and S100 β in the combination group were (17.8 ± 3.6) μmol/L, (16.8 ± 2.7) μg/L, and (17.4 ± 7.5) μg/L, respectively, which were significantly lower than (21.5 ± 3.3) μmol/L, (20.4 ± 3.7) μg/L, and (23.5 ± 5.1) μg/L in the donepezil hydrochloride group ( t = -5.08, -5.27, -4.51, all P < 0.001). The incidence of adverse drug reactions in the combination group was 13.3% (6/45), which was slightly, but not significantly, higher than 8.9% (4/45) in the donepezil group ( χ2 = 0.45, P = 0.502). Conclusion:The combination of donepezil hydrochloride and memantine can effectively improve the mental and behavioral symptoms and cognitive function of patients with AD, improve daily living ability, and do not increase adverse reactions. The combined therapy has high clinical application value.

Objective:To explore the clinical value of 18F-fluoromisonidazole (FMISO) PET/CT hypoxia imaging in early response to heavy ion radiotherapy in patients with non-small cell lung cancer(NSCLC). Methods:From April 2018 to January 2021, the 18F-FMISO PET/CT images of 23 NSCLC patients (19 males, 4 females; age (64.9±10.3) years) who received heavy ion radiotherapy in Shanghai Proton and Heavy Ion Center were retrospectively analyzed. The evaluation parameters included tumor volume (TV), tumor to background ratio (TBR) before and after radiotherapy. Patients were divided into hypoxia group and non-hypoxia group with the baseline TBR value≥1.4 as hypoxia threshold. Wilcoxon signed rank test was used to compare the differences of TV and TBR before and after radiotherapy in 2 groups. Results:Of 23 NSCLC patients, 17 were hypoxia and 6 were non-hypoxia. Compared with the baseline, TV after the radiotherapy (59.44(22.86, 99.43) and 33.78(8.68, 54.44) cm 3; z=-3.05, P=0.002) and TBR after the radiotherapy (2.25(2.09, 2.82) and 1.42(1.24, 1.67); z=-3.39, P=0.001) of the hypoxia group were significantly lower, while TV (16.19(6.74, 36.52) and 8.59(4.38, 25.47) cm 3; z=-1.57, P=0.120) and TBR (1.19(1.05, 1.27) and 1.10 (0.97, 1.14); z=-1.89, P=0.060) of the non-hypoxia group decreased with no significant differences. Conclusions:Hypoxic NSCLC tumors are sensitive to heavy ion radiation. Compared with non-hypoxic tumors, hypoxic tumors respond more quickly, and a significant reduction in TV can be observed early after radiotherapy. Heavy ion radiation can significantly improve tumor hypoxia.

ObjectiveTo explore the possible mechanisms of Shoutai Wan （寿胎丸） in treating recurrent miscarriage （RSA） from the perspective of immune tolerance under the acidic microenvironment at the maternal-fetal interface. MethodsFemale CBA/J mice were randomly divided into normal group， model group， progesterone group， and Shoutai Wan group， with 15 mice in each group. The mice in the normal group and model group were given 0.2 ml distilled water by gavage each day， the Shoutai Wan group given Shoutai Wan decoction 0.15 g/（10 g·d） by gavage， the progesterone group given progesterone tablets 0.44 mg/（10 g·d） by gavage. After gavage for 14 days， the mice were cohabited. Female CBA/J mice in the normal group were mated with male BALB/c mice at a ratio of 2∶1， and female CBA/J mice in the other groups were mated with male DBA/2 mice at a ratio of 2∶1 to establish the RSA mouse model. Vaginal smears were taken from the female mice the next morning， and the appearance of a large number of spermatozoa and the presence of a vaginal plug were considered as the first day of pregnancy. After the appearance of the plug， the mice were continued to be administered according to the previous method until the 10th day of pregnancy. On the 10th day of pregnancy， maternal-fetal interface tissues were collected from each group of mice， and lactate dehydrogenase colorimetric method was used to detect lactate （LA） content； qPCR method and Western blot method were used to detect the expression of immune-related factors interleukin-4 （IL-4）， interferon-gamma （IFN-γ）， transforming growth factor beta 1 （TGF-β1）， and forkhead box protein 3 （Foxp3） mRNA and protein； flow cytometry was used to detect the numbers of helper T lymphocyte 1 （Th1）， helper T lymphocyte 2 （Th2）， regulatory T cell （Treg）， classical macrophage （M1）， and alternative macrophage （M2）. The bivariate Pearson test was used to analyze the correlation between LA content and the numbers of Th1， Th2， Treg， M1， and M2 cells， as well as the correlation between LA content and the expression of IL-4， IFN-γ， TGF-β1， Foxp3 protein， and mRNA. ResultsOn the 10th day of pregnancy， compared with the normal group， the LA content decreased in the model group， and the expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues decreased， while the expression of IFN-γ protein and mRNA increased. The numbers of Th1 and M1 cells increased， while the numbers of Th2， Treg， and M2 cells decreased （P＜0.05 or P＜0.01）. Compared with the model group， the LA content increased in the Shoutai Wan group and progesterone group. The expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues increased， while the expression of IFN-γ protein and mRNA decreased. The numbers of Th1 and M1 cells decreased， while the numbers of Th2， Treg， and M2 cells increased （P＜0.05 or P＜0.01）. The LA content was positively correlated with the numbers of Th2， Treg， and M2 cells， and the expression of IL-4， TGF-β1， Foxp3 protein， and mRNA （P＜0.05 or P＜0.01）； the LA content was negatively correlated with the numbers of Th1， M1 cells， and the expression of IFN-γ protein and mRNA （P＜0.05 or P＜0.01）. ConclusionShoutai Wan may improve immune tolerance by regulating the expression of immune-related factors in the acidic microenvironment at the maternal-fetal interface of RSA model mice， thereby exerting its role in preventing miscarriage.

Objective: To analyze the urinary iodine status of urban and rural residents in some areas of Gansu Province and its related influencing factors, and to provide certain references for scientific iodine intake of urban and rural residents in Gansu Province. Methods: Subjects in Gansu Province with normal thyroid function were recruited in the investigation of thyroid diseases and iodine nutritional status, conducted a questionnaire survey and measured height, weight, waist circumference, collected 1 urine sample, and tested their urinary iodine levels. The urinary iodine levels of different groups were compared based on different gender, region, age, body weight, the waist, and salt intaking. The affecting factors of urinary iodine levels were analyzed by multiple linear regression models. Results: Totally 1 964 subjects were recruited, including 1 099 males, and 865 females. The age was (41.23 ± 14.75) years old. The median urinary iodine of the selected group was 225.60 (158.80, 311.58) μg/L. The urinary iodine level of rural residents was significantly higher than that of urban residents [μg/L: 249.80 (180.58, 336.88) vs 206.25 (148.03, 280.33), Z=-8.015, P < 0.05], and there was no significant difference between the urinary iodine levels of male and female [μg/L: 222.40 (161.60, 298.90) vs 230.60 (158.00, 326.40), P > 0.05]. The composition ratio of < 100 μg/L group in rural areas was lower than that in urban areas (5.14% vs 8.27%, χ²= 7.45, P < 0.05), and the composition ratio of ≥300 μg/L group was higher than that in urban areas (34.93% vs 21.51%, χ²= 43.87, P < 0.05). The composition ratio of ≥300 μg/L group in male was lower than that in female (24.57% vs 31.21%, χ²= 10.73, P < 0.05). The multiple linear regression analysis showed that lived in rural areas, age, moderate and severe salt intaking, student, and weight were independently correlated with urinary iodine levels (β= 0.074, -0.001, 0.059, 0.034, 0.096, -0.003, P < 0.05). And the urinary iodine levels were decreased with age and weight increased (P < 0.05). Conclusions At present, the iodine nutrition level of urban and rural residents in some areas of Gansu Province is generally over the adequate level. The urinary iodine level of rural residents is higher than that of urban residents. In the future, we should pay attention to the impact of different living areas, salt intaking and body weight on urinary iodine levels to prevent thyroid diseases.
