Antibody-drug conjugates(ADCs)are a new type of targeting antibodies that conjugate with highly toxic anticancer drugs via chemical linkers to exert high specificity and efficient killing of tumor cells,thereby attracting considerable attention in precise oncology therapy.Cetuximab(Cet)is a typical antibody that offers the benefits of good targeting and safety for individuals with advanced and inoperable cutaneous squamous cell carcinoma(cSCC);however,its anti-tumor activity is limited to a single use.Cisplatin(CisPt)shows good curative effects;however,its adverse effects and non-tumor-targeting ability are major drawbacks.In this study,we designed and developed a new ADC based on a new cytotoxic platinum(Ⅳ)prodrug(C8Pt(Ⅳ))and Cet.The so-called antibody-platinum(Ⅳ)prodrugs conjugates,named Cet-C8Pt(Ⅳ),showed excellent tumor targeting in cSCC.Specifically,it accurately delivered C8Pt(Ⅳ)into tumor cells to exert the combined anti-tumor effect of Cet and CisPt.Herein,metabolomic analysis showed that Cet-C8Pt(Ⅳ)promoted cellular apoptosis and increased DNA damage in cSCC cells by affecting the vitamin B6 metabolic pathway in tumor cells,thereby further enhancing the tumor-killing ability and providing a new strategy for clinical cancer treatment using antibody-platinum(Ⅳ)prodrugs conjugates.

Sleep-related eating disorder (SRED) is a sleep disorder characterized by repeated involuntary eating and drinking. The clinic of this disease is not rare, but few reports are noted in China; doctors and patients lack of knowledge. This paper reviews the literature on SRED, summarizes the shortcomings of existing research, and proposes future research directions, aiming to provide references for researchers to further explore this field.

OBJECTIVE:
To assess the clinical value of individualized pharmaceutical services for patients receiving vancomycin for severe infections and establish clinical monitoring procedures during vancomycin treatment.
METHODS:
Data were collected from patients with severe infections who received vancomycin treatment with individualized pharmacy services (test group, 144 cases) or without such services (control group, 884 cases) between January, 2017 and December, 2018. Using propensity score matching, the patients in the two groups with comparable baseline data were selected for inclusion in the study (62 in each group), and the efficacy, safety and economic indicators were compared between the two groups.
RESULTS:
The curative effects of the treatment did not differ significantly between the two groups, with the overall response rates of 95.16% in the test group and 91.94% in the control group (
CONCLUSIONS
The participation of clinical pharmacists during the treatment can improve the clinical benefits of vancomycin in patients with severe infections.

OBJECTIVE:
To study the protective effect of enhanced peroxisome proliferator activated receptor γ (PPARγ) pathway against apoptosis of long-term cultured primary nerve cells.
METHODS:
A natural aging model was established in primary rat nerve cells by long-term culture for 22 days. The cells were divided into control group, 0.1, 1.0, 5.0, and 10 μmol/L GW9662 intervention groups, and 0.1, 1.0, 5.0, and 10 μmol/L pioglitazone intervention groups. The cell viability was assessed using MTT assay and the cell morphological changes were observed after the treatments to determine the optimal concentrations of GW9662 and pioglitazone. Double immunofluorescence labeling and flow cytometry were used to observe the changes in the number of viable cells and cell apoptosis following the treatments; immunocytochemical staining was used to assess the changes in the anti-oxidation ability of the treated cells.
RESULTS:
The optimal concentrations of GW9662 and pioglitazone determined based on the cell viability and morphological changes were both 1 μmol/L. Compared with the control group, GW9662 treatment significantly lowered while pioglitazone significantly increased the total cell number and nerve cell counts ( < 0.05), and nerve cells in the cell cultures maintained a constant ratio at about 80% in all the groups ( > 0.05). GW9662 significantly enhanced while pioglitazone significantly lowered the cell apoptosis rates compared with the control group ( < 0.05). GW9662 obviously lowered SOD activity and GSH content in G group ( < 0.05) and increased MDA content in the cells ( < 0.05), and pioglitazone resulted in reverse changes in SOD, GSH and MDA contents in the cells ( < 0.05).
CONCLUSIONS
Activation of PPARγ pathway protects long-term cultured primary nerve cells by enhancing cellular anti-oxidant capacity and reducing cell apoptosis, suggesting a potential strategy for anti-aging treatment of the nervous system through intervention of the PPARγ pathway.

Objective To explore the effect of token on the pain and compliance of wound care of postoperative children with hypospadias, and provide evidence for the pain management and psycho-behavior intervention of children. Methods Selected 80 cases of hypospadias and they were assigned to the experience group and the control group. The control group was guided by conventional nursing intervention method while the experience group was guided by token intervention. Compare the pain score and compliance of two groups. Results The pain score of the experience group were (2.65±1.89), (2.40± 1.73), (2.10±1.43) points, the control group were (4.10±2.52), (3.35±2.09), (2.90±1.75) points. There were significant differences between the two groups (t=2.912, 2.399,- 2.239, all P<0.05). There were significant differences between the two groups for the compliance (χ2=5.415, 7.587, 9.372, all P<0.05). Conclusion Token can relief the pain of wound care of postoperative children with hypospadias, increase the compliance of wound care of the children.

SUMMARY Thehumanembryonicstemcells(hESCs)serveasaself-renewable,genetically-healthy, pluripotent and single source of all body cells,tissues and organs.Therefore,it is considered as the good standard for all human stem cells by US,Europe and international authorities.In this study,the standard and healthy human mesenchymal progenitors,ligament tissues,cardiomyocytes,keratinocytes,primary neurons,fibroblasts,and salivary serous cells were differentiated from hESCs.The human cellular health-safety of NaF,retinoic acid,5-fluorouracil,dexamethasone,penicillin G,adriamycin,lead ace-tate PbAc,bisphenol A-biglycidyl methacrylate (Bis-GMA)were evaluated selectively on the standar-dized platforms of hESCs,hESCs-derived cardiomyocytes,keratinocytes,primary neurons,and fibro-blasts.The evaluations were compared with those on the currently most adopted cellular platforms.Parti-cularly,the sensitivity difference of PM2.5 toxicity on standardized and healthy hESCs derived fibroblasts, currently adopted immortalized human bronchial epithelial cells Beas-2B and human umbilical vein endo-thelial cells (HUVECs)were evaluated.The results showed that the standardized hESCs cellular plat-forms provided more sensitivity and accuracy for human cellular health-safety evaluation.
