Objective:We aimed to investigate the effect of neo-adjuvant chemotherapy on postoperative cognitive dysfunction (POCD) in elderly patients who underwent one-lung ventilation (OLV) surgery. Methods:A total of 90 esophageal carcinoma patients aged 60 years old or older were included. These patients were scheduled for esophagectomy, including two or three-field lymphadenec-tomy, and were randomly divided into two groups based on the American Society of Anesthesiologists status (Ⅰ or Ⅱ) and the Tu-mor-Node-Metastasis (TNM) classification stage (ⅡorⅢ), as follows:the neo-adjuvant chemotherapy group (Group N:n=45) that re-ceived preoperative neo-adjuvant chemotherapy;and the control group (Group C:n=45) that did not receive chemotherapy. The neuro-psychological test was performed 1 d before and 7 d after surgery to evaluate the changes in cognitive function. The incidence of POCD was also determined via the Z-value method in the two groups. Results:A total of 44 patients in Group N and 41 patients in Group C completed the neuropsychological tests. No statistical differences were observed in the demographics, TNM stage, and the intra-and post-operative clinical data between the groups. POCD was observed in 21 of the patients in Group N (47.7%) and 11 of the patients in Group C (26.8%), and the differences were significant (χ2=3.949, P=0.047). Conclusion:Neo-adjuvant chemotherapy can aggravate the impairment of cognitive function in the elderly patients undergoing OLV surgery and can significantly increase the incidence of POCD.

OBJECTIVETo establish an indicator system of risk assessment for mechanical cuts, and to validate the system using examples.

METHODSAn indicator system was proposed by the expert investigation method. The index weight, expert authority coefficient, and degree of coordination were determined. The reasonability and stability of the expert questionnaire were evaluated by the reliability analysis. Some on-site examples were given to validate the indicator system.

RESULTSAn indicator system containing 3 first-class indicators, 10 second-class indicators, and 34 third-class indicators was obtained by screening indicators using the boundary value method and the assignment transformation method. The average expert authority coefficient was 0.79. The average expert coordination coefficient was 0.47. The overall reliability coefficient was 0.884. The scores obtained using the indicator system were significantly correlated with the actual injury results in six workplaces (r=0.866, P<0.01).

CONCLUSIONThe indicator system of risk assessment for mechanical cuts proposed in this study is reasonable and highly consistent with the actual injury results. However, this indicator system still needs further validation and optimization.

This paper aimed at studying the effects of hyaluronic acid (HA) with different molecular weights on the transdermal absorption and retention of reduced glutathione (GSH) in the isolated skin of SD rats. Franz diffusion cell method was used to investigate the effects with different molecular weights HA on the in vitro transdermal penetration of GSH and the storage in different layers of the skin. AutoDock molecular docking was used to study the interaction between GSH and HA. Attenuated total reflection Fourier transformed infrared spectroscopy (ATR-FTIR) and H&E section staining were used to characterize the changes and effects of lipids and proteins in the rat stratum corneum after HA acts on the skin. The results of in vitro transdermal experiments showed that HA with different molecular weights had a significant impact on the amount of GSH passing through the skin, that as the molecular weight of HA increased, the effect of preventing GSH from passing through the skin became stronger, that in terms of skin storage, HA with different molecular weights could increase the storage of GSH in the stratum corneum, and that HA with a molecular weight below 7K could also significantly increase the storage of GSH in the dermis. The molecular docking results showed that HA and GSH had a relatively strong interaction, which could form intermolecular hydrogen bonds; and the results of ATR-FTIR and H&E staining showed that HA could interact with lipids and keratins in the stratum corneum of the skin. Such interaction can increase the permeability of the stratum corneum of the drug, however, as a water-soluble GSH, it may be involved in the formation of intermolecular hydrogen bonds with HA. In the structure of HA hydrogel, the amount of GSH drug passing through the intact skin is reduced; but at the same time, this interaction also provides a reservoir for the formation of GSH, thus increasing its storage in the skin. Through comparison of the storage capacity of GSH in the stratum corneum and dermis of the isolated skin due to the increase of HA with different molecular weights, it has been found that the storage capacity of HA with low relative molecular weight is the best.
