A sensitive and effective method for determination of 16 kinds of antibiotics, including tetracycline, sulfonamide, fluoroquinolone and macrolide, in livestock and poultry manure using solid phase extraction-ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established.Aiming at the chemical properties and sample impurities of the target, the parameters such as mass spectrum conditions, types of extraction and ultrasonic power were optimized.Finally, the samples were extracted with 50% acetonitrile in phosphate buffer solution (pH =4) for three times, followed by ultrasonic steaming, centrifugal and rotary, dilution, and purified by SAX-HLB.After sample loading, the solid phase was washed with 10 mL of methanol-acetone (80∶20, V/V), evaporated to near dryness at 35℃, and then re-dissolved and vortex mixed in 1 mL of 0.1% formic acid∶methanol (1∶1, V/V).The extracts were analyzed with UPLC-MS/MS and calculated by external standard method based on the monitored product ion.The results indicated that the average spiked recoveries of tetracycline, sulfonamide, fluoroquinolone and macrolide in manure were 56.4%-94.6% with relative standard deviations (RSDs) of 2.6%-19.8%, the LODs (S/N=3) were 0.01-2.50 μg/kg, and the LOQs (S/N=10) were 0.05-7.90 μg/kg.The method was simple with high stability, high sensitivity and good reproducibility, and suitable for the simultaneously determination of many antibiotics in animal and poultry manure.

Objective To investigate the effects of probiotics combined with dietary intervention on pe-ripheral blood glucose and lipid metabolism indicators,placental tissue insulin signaling pathway proteins ex-pression and pregnant outcome in the patients with gestational diabetes mellitus(GDM).Methods A total of 83 patients with GDM in this hospital from December 2021 to December 2022 were selected as the study sub-jects and divided into the probiotics group(probiotics combined with diet intervention,43 cases)and control group(simple diet intervention,40 cases)by the random number table method.The levels of peripheral blood glucose,lipid and insulin resistance related indicators before the intervention and in 8 weeks after the interven-tion were compared between the two groups.The histological changes of placenta were observed by HE stai-ning.The pathological indicators were compared between the two groups.The expression levels of insulin re-ceptor substrate-1(IRS-1),glucose transporter 4(GLUT4)and synaptosome-associated protein of 23 kDa(SNAP23)in placental tissue were detected by immunohistochemistry.The pregnant adverse outcomes were compared between the two groups,and the clinical efficacy of probiotics was evaluated.Results Compared with the control group,the levels of fasting blood glucose(FBG),fasting insulin(FINS),serum triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)in 8 weeks after intervention in the probiotics group were significantly decreased(P<0.05),and the level of serum high density lipoprotein cholesterol(HDL-C)was significantly increased(P<0.05).There were no significant differences in the incidence rates of poor villi maturation,thickening of dry villi arterioles and capillary filling in villi interstitial between the two groups(P>0.05).Compared with the control group,the expression levels of IRS-1,GLUT4 and SNAP23 in placen-tal tissue of the probiotics group were significantly increased(P<0.05).The incidence rates of neonatal hy-poglycemia and neonatal hyperbilirubinemia in the probiotics group were significantly lower than those in the control group(P<0.05).Conclusion Compared with simple dietary intervention,probiotics combined with dietary intervention has more advantages in improving glucose and lipid metabolism of GDM patients,moreo-ver reduces the adverse events occurrence in newborns.

ObjectiveTo systematically analyze the typical mental health conditions and psychological disorders of children with intellectual and developmental disabilities (IDD), to construct a mental health service system and psychological interventions to these mental health conditions of children with IDD . MethodsBased on the framework of the World Health Organization Family International Classifications (WHO-FICs), the mental health conditions and related functioning were analyzed, and the mental health service framework and proposed mental health interventions were constructed.There were six main categories of mental health conditions for children with IDDConclusionThis study systematically analyzed the typical mental health status and related psychological functional impairments of children with IDD. Based on the World Health Organization health service system, a mental health service framework for children with IDD was constructed. Referring to the WHO's continuum of health services, a system of psychological intervention methods for children with IDD was established. Furthermore, the WHO-FICs were used to describe and code the functions of children with IDD, and the ICHI-β3 was applied to code and analyze the related psychological interventions. Resultsmood disorders (anxiety and depression), behavioral disorders (disruptive disorders and challenging behaviors, aggressive behaviors), traumatic disorders (post-traumatic stress disorder), mental disorders (schizophrenia), suicide and self-harm, and learning disabilities (developmental learning disabilities, attention deficit hyperactivity disorder). Mental health services for children with IDD involved in six dimensions: leadership and governance, fundraising, human resources, service delivery, mental health technologies, and information and research. Mental health services went through the continuum of health services from prevention, treatment, rehabilitation to health promotion. We delivered mental health services for children with IDD in three aspects: identifying and diagnosing mental health problems or conditions, analyzing the main factors caused mental health problems, and analyzing the environmental factors. Mental health service interventions mainly covered five categories: antidepressants, psychotherapy, stress management training, physical exercise training, healthy lifestyle education, consultation and support. Children with IDD may obtain the mental health services in hospitals, rehabilitation institutions, community and school settings.

OBJECTIVE:
To evaluate the effects of the pestle needling therapy on the vibration perception threshold (VPT) and the quality of life (QOL) in the patients of high-risk diabetic foot.
METHODS:
A total of 132 patients of high risk diabetic foot were randomized into an observation group and a control group, 66 cases in each one. In the control group, the routine treatment and nursing for diabetes were applied. In the observation group, on the base of the treatment as the control group, the pestle needling therapy was used at , , , Zusanli (ST 36), Yongquan (KI 1), Sanyinjiao (SP 6) and Taixi (KI 3). The intervention with the pestle needling therapy was given once every day, consecutively for 4 weeks. The follow-up visit was conducted in 3 months and 6 months after the intervention. Vibration perception threshold (VPT) was observed before and after intervention in the two groups. Separately, before intervention, at the end of intervention, 3 months after intervention and 6 months after intervention, the type 2 diabetes mellitus quality life scale (DMQLS), the revised edition was adopted to compare the QOL between the two groups. The effects were evaluated in the two groups.
RESULTS:
After intervention, the VPT and QOL were all improved in the two groups (<0.01, <0.05). In the observation group, after intervention, VPT at the first toes and the dorsum of the feet was lower than the control group at the same time point (all <0.01). In the observation group, the total scores and the score of each dimension item in the DMQLS of the revised edition were all lower than the control group correspondently at the end of intervention, 3 months after intervention and 6 months after intervention (<0.01, <0.05). The repeated ANOVA results showed that the differences were significant in the total scores and the score of each dimension in the aspects of time, inter-group and interaction effect (<0.01, <0.05). The total scores and score of each dimension item in the DMQLS were lower than those the earlier time point (<0.01, <0.05). The total effective rate was 100.0% in the observation group, which was superior to 95.1% (59/62) in the control group (<0.05).
CONCLUSION
The pestle needling therapy reduces the foot VPT and improves the sensory nerve function of the foot and the QOL in the patients of high-risk diabetic foot.
