Corneal biomechanics after small incision lenticule extraction and femtosecond laser in situ keratomileusis: A systematic review and meta-analysis.

Background: Small incision lenticule extraction (SMILE) and femtosecond laser in situ keratomileusis (FS-LASIK) have been extensively studied as the main surgical methods for corneal refractive surgery. However, there is no consensus on whether SMILE is superior to FS-LASIK in corneal biomechanics. Therefore, this systematic review and meta-analysis used the results of ocular response analyzer and corvis ST to explore whether SMILE is superior to FS-LASIK in corneal biomechanics.

A retrospective study on unresectable or inoperable head and neck cancers treated with stereotactic ablative brachytherapy.

Purpose: The aim of the present study was to assess the clinical efficacy and safety of stereotactic ablative brachytherapy (SABT) for unresectable or inoperable head and neck cancers.

Material And Methods: This study retrospectively assessed clinical data of 37 patients with unresectable or inoperable head and neck cancers treated with SABT from October 2016 to October 2021. Variables evaluated included local efficacy, local control rate (LCR), overall survival (OS) rate, and radiological adverse effects.

Gelatin sponge microparticles for transarterial chemoembolization combined with regorafenib in hepatocellular carcinoma: a single-center retrospective study.

Background: The treatment of advanced hepatocellular carcinoma (HCC) is challenging. The positive effect of gelatin sponge microparticles for transarterial chemoembolization (GSMs-TACE) in the treatment of Barcelona Clinic Liver Cancer (BCLC) stage C and large HCC has been confirmed by previous studies. This study initially explored the efficacy and safety of GSMs-TACE combined with regorafenib in patients with unresectable HCC who failed first-line sorafenib and/or lenvatinib therapy.

Clinical efficacy and safety analysis of CT-guided I implantation in the treatment of recurrent or metastatic pelvic malignant tumor.

Purpose: This study was conducted to evaluate the clinical efficacy and safety of computed tomography (CT)-guided I implantation in the treatment of recurrent or metastatic pelvic malignant tumor.

Methods And Materials: This retrospective study analyzed the data of 30 patients with recurrent and metastatic pelvic malignant tumor who were treated with CT-guided I implantation between January 2016 and December 2020. Disease control rate, objective remission rate, overall survival (OS), pain relief rate, quality of life score, and complications were evaluated after the followup.

Analysis of the clinical efficacy and safety of computerized tomography-guided 125 I seed implantation in the treatment of non-small cell lung cancer that relapsed after chemoradiotherapy.

Purpose: The purpose is to evaluate the clinical efficacy and safety of computerized tomography (CT)-guided 125I seed implantation in the treatment of recurrent non-small cell lung cancer (NSCLC) after chemoradiotherapy.

Materials And Methods: We retrospectively analyzed the data of 30 recurrent NSCLC patients in our institute from January 2016 to June 2020. According to the preoperative Treatment planning system plan, CT was used to guide 125I seed implantation into 30 evaluable lesions in the lungs.

Effect of system energy on quantum signatures of chaos in the two-photon Dicke model.

We have studied entanglement entropy and Husimi Q distribution as a tool to explore chaos in the quantum two-photon Dicke model. With the increase of the energy of a system, the linear entanglement entropy of a coherent state prepared in the classical chaotic and regular regions becomes more distinguishable, and the corresponding relationship between the distribution of time-averaged entanglement entropy and the classical Poincaré section has clearly been improved. Moreover, Husimi Q distribution for the initial states corresponding to the points in the chaotic region in the higher-energy system disperses more quickly than that in the lower-energy system.
