Neuraxial opioids, widely used in obstetric and perioperative pain management, often lead to unwanted itch, reducing patient satisfaction. While the μ-opioid receptor has been implicated in opioid-induced itch, the genetic basis for variable itch incidence remains unknown. This study examined 3616 patients receiving epidural opioids, revealing an itch occurrence of 26.55%, with variations among opioid types and gender. Analysis of the OPRM1 gene identified six single-nucleotide polymorphisms, notably rs1799971 (A118G), that correlated with opioid-induced itch. Mouse models with an equivalent A112G mutation showed reduced neuraxial opioid-induced itch and light touch-evoked itch, mirroring human findings. The 118G allele demonstrated an anti-itch effect without impacting analgesia, addiction, or tolerance, offering insights for risk stratification and potential anti-itch pretreatment strategies.

Objective:To explore the characteristics of unmet needs and services of rehabilitation for people with hearing disability (PHD). Methods:A total of 219 473 PHDs administration data of unmet needs and services of rehabilitation at provincial level were sampled (2019) and analyzed the characteristics of needs and services of rehabilitation with multiple response analysis, and the related factors of needs and services with Logistic regression. Results:There were 47 657 (21.7%) PHDs reported their unmet needs of rehabilitation, from high to low were assistive devices (65.5%), medicine (22.7%), nursing care (19.1%), functional training (16.2%) and surgery (2.2%). There were 34 684 (18.8%) PHDs reported their received services, from high to low were assistive devices (59.8%), medicine (22.5%), functional training (19.7%), nursing care (19.4%) and surgery (1.8%). The logistic regression model showed that age, types of household registration and severities of disabilities related with the reported unmet needs and received services (P < 0.001). Conclusion:PHDs mainly reported unmet needs in the fields of assistive devices, medicine, and rehabilitation training. The reported unmet needs for PHDs had matched the received services structurally. It proposed to use modern science and technology to develop services delivery and to improve accessibility and quality of rehabilitation services.

Objective: To observe the effect of modified Chaihu Shugantang on the expression of miRNA-204 in hippocampus of epileptic mice, and to explore its mechanism of neuroprotection. Method: The sixty mice were randomly divided into 6 groups:normal group, model group (pilocarpine 180 mg·kg^-1), and modified Chaihu Shugantang group (7 g·kg^-1·d^-1), modified Chaihu Shugantang+miRNA-204 mimic group (7 g·kg^-1·d^-1+ 2 μL), modified Chaihu Shugantang+miRNA-204 inhibitor group (7 g·kg^-1·d^-1+2 μL), carbamazepine group (30 mg·kg^-1·d^-1),each was given intragastric administration for 2 weeks,using pilocarpine to cause epilepsy in mice, respectively, add flavor to Bupleurum after intragastric administration, inhibition and overexpression of miRNA-204, the mice were sacrificed and their hippocampus tissues were harvested.The indicators of each group were observed, Real-time quantitative PCR detecting system (Real-time PCR) was used to detect mouse hippocampal miRNA-204 expression, Western blot analysis of autophagy-related protein microtubule-associated protein light chain 3 (LC3), autophagy-associated marker protein 7 (ATG7) expression, hematoxylin pathological condition of hippocampus in each group was observed by hematoxylin-eosin(HE)staining.The autophagy of hippocampus in each group was observed by transmission electron microscopy. Result: Compared with normal group, the expression of miRNA-204 was significantly decreased in model group (P<0.01), the pathological changes in the hippocampal C1 area were the most obvious, the expression of ATG7, LC3Ⅱ/LC3Ⅰ was increased (P<0.01), and the autophagy was small. Compared with model group, the expression of miRNA-204 in the hippocampus of the modified Chaihu Shugantang group was increased (P<0.05), the pathological changes in the hippocampal C1 area were alleviated, the expression of ATG7, LC3Ⅱ/LC3Ⅰ was decreased (P<0.05), and the autophagy was small. The number of body decreased,the expression of miRNA-204 in hippocampus of modified Chaihu Shugantang+miRNA-204 mimic group was significantly increased (P<0.01), the pathological changes in hippocampal C1 area were the lightest, and the expression of ATG7, LC3Ⅱ/LC3I was decreased (P<0.01), the number of autophagosomes was the least.Compared with modified Chaihu Shugantang group, the above-mentioned indicators of modified Chaihu Shugantang+miRNA-204 inhibitor group had the same change trend and the change range decreased (P<0.05). Conclusion: Modified Chaihu Shugantang can improve the pathological changes of hippocampus in mice with epilepsy and play a neuroprotective role. The mechanism may be to increase the expression of miRNA-204 in hippocampus of mice with epilepsy, inhibit excessive autophagy of neurons and reduce apoptosis.

OBJECTIVES: To evaluate whether garlicin post-conditioning can attenuate myocardial ischemiareperfusion injury in a catheter-based porcine model of acute myocardial infarction (AMI) by affecting adhesion molecules integrin β1/CD29 and platelet endothelial cell adhesion molecule-1 (PECAM-1/CD31). METHODS: Twenty-two swine were devided into 3 groups: 6 in a sham-operation group, and 8 each in the model and garlicin groups. AMI porcine model was established in the model and garlicin groups. The distal parts of the left anterior descending coronary artery in the animals of the model and garlicin groups were occluded by dilated balloon for 2 h, followed by reperfusion for 3 h. Garlicin (1.88 mg/kg) was injected over a period of 1 h, beginning just before reperfusion, in the garlicin group. Real-time polymerase chain reaction, immunohistochemistry and Western blot were carried out to detect mRNA and protein expressions of CD29 and CD31 3 h after reperfusion. RESULTS: Hematoxylin-eosin staining showed a better myocardial structure in the garlicin group after reperfusion. Compared to the model group, garlicin inhibited both the mRNA and protein expression of CD29 and CD31 in reperfusion area and no-reflflow area (P<0.05 respectively). CONCLUSIONS Garlicin post-conditioning induced cardio-protection against myocardial ischemia-reperfusion injury in this catheter-based porcine model of AMI. The cardio-protective effect of garlicin is possibly owing to suppression of production of CD29 and CD31, by inhibition of the mRNA expression of CD29 and CD31.

OBJECTIVETo investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus (GDM).

METHODSA total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation (WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity.

RESULTSAge, pre-pregnant body weight (BW), and body mass index (BMI) were associated with increased risk of GDM. Fat mass (FM), fat mass percentage (FMP), extracellular water (ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass (FFM), muscular mass (MM), and intracellular water (ICW) were associated with a decreased risk of GDM.

CONCLUSIONMaternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.

OBJECTIVETo evaluate whether garlicin can prevent reperfusion no-reflow in a catheter-based porcine model of acute myocardial infarction (AMI).

METHODSTwenty-two male Chinese mini swines were randomized into 3 groups: sham-operation group (n=6), control group (n=8), and garlicin group (n=8). The distal part of left anterior descending coronary artery (LAD) in swines of the latter two groups was completely occluded by dilated balloon for 2 h and a successful AMI model was confirmed by coronary angiography (CAG) and electrocardiograph (ECG), which was then reperfused for 3 h. In the sham-operation group, balloon was placed in LAD without dilatation. Garlicin at a dosage of 1.88 mg/kg was injected 10 min before LAD occlusion until reperfusion for 1 h in the garlicin group. To assess serial cardiac function, hemodynamic data were examined by catheter method before AMI, 2 h after occlusion and 1, 2, and 3 h after reperfusion. Myocardial contrast echocardiography (MCE) and double staining with Evans blue and thioflavin-S were performed to evaluate myocardial no-reflow area (NRA) and risk area (RA).

RESULTSLeft ventricular systolic pressure and left ventricular end-diastolic pressure significantly improved in the garlicin group after reperfusion compared with the control group P<0.05) and 2 h after AMI (P<0.05). MCE showed garlicin decreased reperfusion NRA after AMI compared with the control group (P <0.05). In double staining, NRA/RA in the garlicin group was 18.78%, significantly lower than that of the control group (49.84%, P<0.01).

CONCLUSIONSGarlicin has a preventive effect on the porcine model of myocardial infarction reperfusion no-reflow by improving hemodynamics and decreasing NRA.
