Objective:To evaluate the predictive value of preoperative frailty combined with nutritional status for prolonged postoperative ileus (PPOI) in the patients with gynecological malignancies.Methods:Patients undergoing elective surgery for gynecological malignancies in the Affiliated Hospital of Jiangnan University from April 2022 to February 2023 were selected. The Frail scale was used to evaluate the frailty within 24 h of admission, and the nutritional status was evaluated by the Controlling Nutritional Status score. The general characteristics of patients and occurrence of PPOI were recorded, and the risk factors for PPOI were analyzed by multivariate logistic regression. The ability of frailty, nutritional status and their combination to predict PPOI was assessed by the receiver operating characteristic curve.Results:Two hundred and fourteen patients were finally included, 52 cases developed of PPOI, and 98 cases were frail patients. Preoperative frailty combined with moderate to severe malnutrition was an independent risk factor for PPOI in the patients with gynecological malignancies ( P<0.05), and the area under the curve in predicting the occurrence of PPOI was 0.796 (95% confidence interval 0.736-0.857) in the patients with gynecological malignancies. Conclusions:Preoperative frailty combined with moderate to severe malnutrition has a higher accuracy in predicting PPOI in the patients with gynecological malignancies.

Tuberous sclerosis complex(TSC)is an autosomal dominant skin-nerve syndrome with diverse clinical manifestations.Epilepsy is the most common neurological manifestation.Vigabatrin(VGB)is an inhibitory neurotransmitter γ-aminobutyric acid(GABA)analogue.It reduces the degradation of GABA by irreversibly binding to GABA transaminase, thereby increasing the level of GABA in the central nervous system and exerting anti-epileptic effects.It is suitable for the treatment of various types of epilepsy related to TSC.In recent years, the preventive effect of VGB in TSC-related epilepsy has attracted wide attention.There is a certain degree of adverse reactions during the use of VGB, the most noteworthy of which is the visual field and central nervous system changes.This article reviews the efficacy and safety of VGB in the treatment of TSC-related epilepsy.

Objective    To determine the effectiveness of continuous intercostal nerve block for pain relief after thoracotomy. Methods    From November 2017 to October 2018, 120 patients who received thoracotomy procedure in our hospital were collected, including 60 males and 60 females aged 40-77 (58.10±7.00) years. The patients were randomly allocated into three groups by digital table including a continuous intercostal nerve block group (group A, n=40), a single intercostal nerve block group (group B, n=40), and an epidural analgesia group (group C, n=40). All the groups received the same basic analgesia. The pain scores and rescue analgesic doses were compared. Results    On postoperative day (POD) 0, all groups achieved effective pain control, and the visual analogue score was 2.02±0.39 points in the group A, 2.13±0.75 points in the group B and 2.03±0.69 points in the group C (P>0.05). On POD 0-2 and POD 3-4 (without basement analgesia), there was no significant difference between the group A and group C in the pain scores (2.08±0.28 points vs. 1.93±0.53 points, 3.20±0.53 points vs. 3.46±0.47 points, P>0.05), however, the difference between POD 0-2 and POD 3-4 in each group was stastically different (group A, 2.08±0.28 points vs. 3.20±0.53 points; group B, 2.42±0.73 points vs. 5.45±0.99 points; group C 1.93±0.53 points vs. 3.46±0.47 points, P<0.05). In terms of the rescue analgesic doses, there was no significant difference between the group A and group C (220.00±64.08 mg vs. 225.38±78.85 mg, P>0.05); it was larger in the group B than that in the group A and group C (343.33±119.56 mg vs. 220.00±64.08 mg; 343.33±119.56 mg vs. 225.38±78.85 mg, P<0.05). Conclusion    Multimodal analgesia is an optimal choice in the initial stage after thoracotomy surgery. Continuous intercostal nerve block is an effective way to pain management in patients with thoracotomy.

Tremendous efforts have been devoted to the enhancement of drug solubility using nanotechnologies, but few of them are capable to produce drug particles with sizes less than a few nanometers. This challenge has been addressed here by using biocompatible versatile -cyclodextrin (-CD) metal-organic framework (CD-MOF) large molecular cages in which azilsartan (AZL) was successfully confined producing clusters in the nanometer range. This strategy allowed to improve the bioavailability of AZL in Sprague-Dawley rats by 9.7-fold after loading into CD-MOF. The apparent solubility of AZL/CD-MOF was enhanced by 340-fold when compared to the pure drug. Based on molecular modeling, a dual molecular mechanism of nanoclusterization and complexation of AZL inside the CD-MOF cages was proposed, which was confirmed by small angle X-ray scattering (SAXS) and synchrotron radiation-Fourier transform infrared spectroscopy (SR-FTIR) techniques. In a typical cage-like unit of CD-MOF, three molecules of AZL were included by the -CD pairs, whilst other three AZL molecules formed a nanocluster inside the 1.7 nm sized cavity surrounded by six -CDs. This research demonstrates a dual molecular mechanism of complexation and nanoclusterization in CD-MOF leading to significant improvement in the bioavailability of insoluble drugs.
