The aim of this study is to investigate the protective effect of idebenone (IDE) combined with borneol (BO) against Parkinson's disease (PD). In this study, wild-type AB zebrafish and transgenic Tg ( vmat2: GFP) zebrafish with green fluorescence labeled dopamine neurons were used to establish the PD model with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP). Following drug treatment, the behavioral performance and dopamine neuron morphology of zebrafish were evaluated, and regulation of dopamine signaling pathway-related genes was determined using RT-qPCR. The results showed that IDE combined with BO improved the behavioral disorders of zebrafish such as bradykinesia and shortening movement distance, also effectively reversed the damage of MPTP-induced dopaminergic neurons. At the same time, the expression of dopamine synthesis and transportation-related genes was up-regulated, and the normal function of the signal transduction pathway was restored. The combination showed a better therapeutic effect compared to the IDE monotherapy group. This study reveals the protective mechanism of IDE combined with BO on the central nervous system for the first time, which provides an important experimental basis and theoretical reference for clinical combination strategy in PD treatment.

Objective:To investigate the relationship between adiponectin (ADIPOQ) gene polymorphism and postpartum type 2 diabetes mellitus (T2DM) in pregnant women with gestational diabetes mellitus (GDM).Methods:A retrospective study was conducted on 236 GDM postpartum women admitted to the Affiliated Hospital of Jining Medical College from June 2020 to June 2021 as observation subjects. They were divided into a T2DM group and a non T2DM group based on the occurrence of T2DM after delivery. The clinical data of the two groups were compared. The double deoxygenation end termination method was used to detect the single nucleotide polymorphism (SNP) of the ADIPOQ gene, and the four loci rs17366568, rs822395, rs1501299, and rs2241766 were classified. The relationship between ADIPOQ genotype polymorphism and postpartum T2DM was analyzed using a logistic regression model.Results:The G allele carrying the rs2241766 locus in ADIPOQ gene was negatively correlated with the occurrence of T2DM ( OR=0.71, 0.68, P<0.05). Compared with T2DM patients with TT genotype, the GT+ GG genotype at the rs2241766 locus had a lower risk of occurrence for gestational age ≥2 and HbA 1c>85%. Similarly, T2DM patients with pre pregnancy body mass index (BMI)>25 kg/m 2 were more likely to be carriers of the rs2241766 TT genotype ( P=0.026). The (GT+ TT) genotype carrying the T allele at the rs1501299 locus was a protective factor for gestational age and HbA 1c in T2DM patients. Conclusions:The rs2241766 and rs1501299 polymorphisms of the ADIPOQ gene are associated with susceptibility to postpartum T2DM in GDM women. Individuals with rs2241766 and rs1501299 mutant genotypes belong to the high-risk population for T2DM.

ObjectiveBased on response surface methodology combined with principal component analysis（PCA）， the optimal decocting process of Moringa oleifera leaf standard decoction was optimized， and its multi-index quality evaluation system was established， in order to provide scientific basis for the quality control of this standard decoction. MethodResponse surface methodology and PCA were used to optimize the decoction process by taking the relative peak areas of 8 characteristic peaks and dry extract yield as indexes. Based on this， the quality of 15 batches of the standard decoction was evaluated by high performance liquid chromatography（HPLC） characteristic chromatogram， determination of major components（neochlorogenic acid， L-tryptophan， cryptochlorogenic acid， vicenin-2， isoquercetin， astragalin）， determination of active parts（total flavonoids， total organic acids， total polysaccharides， total α-amino acids， total sinapine）， dry extract yield， specific gravity and pH. ResultThe optimal decocting process was to soak M. oleifera leaves（100.00 g） for 30 min and decoct twice with the first decoction of 12 times the amount of water for 30 min and the second decoction of 10 times the amount of water for 20 min. Standard decoction containing 0.2 g·mL^-1 of crude drug was defined by x¯±30%， the specific gravity was 0.722-1.340， pH was 3.86-7.16， dry extract yield was 23.1%-42.9%， and the alcohol-soluble extract content was 8.26%-15.34%. Calculated according to the dried products of the standard decoction， the contents of neochlorogenic acid， L-tryptophan， cryptochlorogenic acid， vicenin-2， isoquercetin and astragalin were 1.99-3.69， 1.20-2.22， 1.44-2.67， 0.53-0.99， 2.45-4.55， 1.22-2.26 mg·g^-1， the relative transfer rates relative to the herbs were 34.37%-63.83%， 62.43%-115.94%， 64.65%-120.06%， 56.98%-105.82%， 37.46%-69.57%， 41.81%-77.64%， respectively. The contents of total flavonoids， total organic acids， total polysaccharides， total α-amino acids， total sinapine were 10.19-18.92， 11.82-21.96， 94.07-174.71， 42.69-79.27， 9.55-17.73 mg·g^-1， the relative transfer rates for herbs were 25.72%-47.77%， 41.78%-77.59%， 64.90%-120.54%， 42.30%-78.57%， 34.99%-64.99%， respectively. ConclusionThe optimized decocting technology of M. oleifera leaf standard decoction is stable and feasible， and the established multi-indicator quality evaluation system can lay the foundation for the quality control of this standard decoction.

Objective:To develop and validate a risk prediction model for cognitive frailty in elderly patients with type 2 diabetes.Methods:A total of 483 elderly patients with type 2 diabetes who visited Tianjin First Central Hospital from June to December 2022 were selected using convenience sampling. They were randomly divided into a modeling group ( n=338) and a validation group ( n=145). Data were collected using a self-designed general information questionnaire, the Short-Form Mini Nutritional Assessment (MNA-SF), the Geriatric Depression Scale-15 (GDS-15), the Frailty Phenotype (FP), the Montreal Cognitive Assessment (MoCA), and the Clinical Dementia Rating (CDR). Logistic regression analysis was performed to identify the influencing factors. A cognitive frailty risk prediction nomogram model was constructed based on the results. The model was validated in the validation group, and its predictive performance and clinical applicability were evaluated using the area under the receiver operating characteristic curve ( AUC), calibration curve, and clinical decision curve analysis. A total of 483 questionnaires were distributed and all were returned as valid, resulting in a 100.0% response rate. Results:The prevalence of cognitive frailty in the 483 elderly patients with type 2 diabetes was 20.3% (98/483). Age, regular exercise, duration of diabetes, HbA1c levels, depression and nutritional status were identified as predictive factors in the model. The AUC of the model was 0.886, and the Hosmer-Lemeshow test showed a χ 2 value of 8.004 ( P=0.433). The optimal cutoff value was 0.335, and the accuracy was 89.0%. Conclusions:The prediction model demonstrates good fit and strong predictive performance, and can intuitively and easily identify elderly patients with type 2 diabetes who are at high risk of cognitive frailty, providing a reference for early screening and intervention.

ObjectiveTo evaluate the quality of Mori Cortex from different producing areas by the entropy weight-technique for order preference by similarity to an ideal solution（TOPSIS）， and to provide a new evaluation method for the quality control of Mori Cortex. MethodAccording to the five key indexes of color， thickness， texture， powdery and cortex remain， a subjective scoring table was designed to evaluate the appearance of Mori Cortex. High performance liquid chromatography（HPLC） was used to determine the fingerprint and the contents of multiple components（mulberroside A， chlorogenic acid， oxyresveratrol， mulberroside C， sanggenone D， sanggenone C， morusin）， and chemometrics was used to explore the differential components of Mori Cortex from different habitats. On this basis， TOPSIS was used to comprehensively evaluate the quality of Mori Cortex from different habitats， and SPSS 22.0 software was used to carry out bivariate correlation analysis between thickness and appearance color with contents of seven components of Mori Cortex. ResultThose with lighter color， thicker root bark， tougher texture， sufficient powder and less cortex remain scored higher， and the top five were all from Anhui. The established fingerprint and determination methods were stable and reliable. Partial least squares-discriminant analysis（PLS-DA） screened three components with the variable importance in the projection（VIP） value>1（mulberroside A， sanggenone D， sanggenone C）， which made an important contribution to the difference in the origin of Mori Cortex. Correlation analysis showed that there was a significantly positive correlation between mulberroside C with lightness value（L^*） and total chromaticity value（E^*ab） and mulberroside A with yellow-blue value（b^*）（P<0.05， P<0.01）， a significantly negative correlation between sanggenone C with b^* and between morusin with L^*（P<0.05， P<0.01）. And there was a significantly negative correlation between mulberroside A， chlorogenic acid， and morusin with thickness（P<0.01）， a clearly negative correlation between sanggenone D with thickness（P<0.05）， a significantly positive correlation between sanggenone C with thickness（P<0.01）. TOPSIS comprehensive scores showed that the samples from Anhui had a good score and ranked high. ConclusionThere are great differences in the quality of Mori Cortex from different habitats， and those with the close habitats show similar characteristics in appearance and component content， and lighter color and less cortex were positively correlated with the quality. Among them， the quality of Mori Cortex from Anhui is relatively good.

ObjectiveTo explore the influence of Xiaoai Jiedu prescription （XJP）-containing serum on natural killer （NK） cells′ lethal effect on colon cancer cells and the molecular mechanism. MethodXJP-containing serum （0.1%， 0.5%， 1%， 5%， 10%） was used to treat HCT-116 cells and NK-92MI cells respectively for 24 h， and methyl thiazolyl tetrazolium （MTT） assay was employed to detect cell proliferation. Then， low-concentration （0.1%， 0.5%， 1%） XJP-containing serum was selected to treat co-cultured HCT-116 cells and NK-92MI cells for 24 h and calcein acetoxymethyl ester/propidium iodide （Calcein-AM/PI） was applied to detect the killing effect of NK cells on colon cancer cells. Flow cytometry was used to detect apoptosis of colon cancer cells， Western blot the expression of apoptosis-related proteins and signal transducer and activator of transcription 4 （STAT4） pathway-related proteins， and enzyme-linked immunosorbent assay （ELISA） the secretion of interferon （IFN）-γ. ResultHigh-concentration （5%， 10%） XJP-containing serum inhibited the proliferation of HCT-116 and NK-92MI cells （P<0.01）， while low-concentration （0.1%， 0.5%， 1%） XJP-containing serum had no obvious influence on cell proliferation compared with the blank group. As compared with the blank group， low-concentration XJP-containing serum enhanced the killing activity of NK cells against colon cancer cells in a concentration-dependent manner （P<0.01）， and induced apoptosis of colon cancer cells （P<0.01）. Moreover， XJP-containing serum （0.1%， 0.5%， 1%） down-regulated the expression of B-cell lymphoma 2 （Bcl-2） and B-cell lymphoma-extra large （Bcl-xl）， and up-regulated the expression of Bcl-2-associated X （Bax） compared with the blank group （P<0.05， P<0.01）. Compared with the co-culture group， XJP-containing serum （0.1%， 0.5%， 1%） increased the expression of p-STAT4 and IFN-γ （P<0.05）. ELISA result showed that XJP-containing serum （0.1%， 0.5%， 1%） raised IFN-γ secretion （P<0.01）. ConclusionXJP-containing serum can enhance the activity of NK cells to kill colon cancer cells. The mechanism is the likelihood that it activates STAT4 pathway， increases IFN-γ secretion by NK cells， down-regulates the expression of Bcl-xl and Bcl-2， and up-regulates the expression of Bax， thereby promoting the apoptosis of colon cancer cells.
