To investigate changes in the corneal shape caused by fluid-gas exchange after vitrectomy. This retrospective case-control study included 43 eyes that underwent a combination of cataract surgery and vitrectomy. The corneal shape was measured using anterior segment optical coherence tomography CASIA2. ⋯ There was also a significant increase in the real K value in the higher-order irregular astigmatism components (Steel-Dwass test; P < .05) for longer periods in the gas versus the nongas group. The shape of the posterior cornea increased in all components in the gas group on the first day after surgery (spherical power -6.35 ± 0.20, regular astigmatism 0.32 ± 0.12, asymmetry 0.22 ± 0.13, and higher-order irregular astigmatism 0.12 ± 0.05, Steel-Dwass test; P < .05). Postoperative changes caused by surgical invasion in the corneal shape appeared to be greater in the gas versus the nongas group, in addition to affecting the time periods of the postoperative corneal shape changes.

Shear wave elastography and strain elastography are two new ultrasonic techniques developed rapidly in recent years. Changes in tissue elasticity occur after normal tissue changes. Elastography technique transforms the elastic information of tissue into optical information for display. Thus more intuitive display of tissue elasticity. Due to the differences in principles and related imaging parameters between the two elastic imaging methods, and the acquisition and interpretation of image data in strain elastic imaging method largely depends on the experience of inspectors, and due to the significant differences between the techniques of inspectors, As a result, conflicting results have been obtained in different scholars' studies on the accuracy comparison of the two elastography techniques in the diagnosis of breast tumors. This meta-analysis aims to compare the accuracy of the two elastography methods in the diagnosis of breast tumors, so as to provide more accurate diagnostic means for patients with breast tumors. The final results will show which elastography method is more accurate in the diagnosis of breast tumors, reduce unnecessary biopsies and provide a reference for clinical decision making. ⋯ This study was not funded.

Posttraumatic headache (PTH) after traumatic brain injury (TBI) is a common clinical symptom, which refers to a headache that occurs after TBI. Acupuncture is often used for the treatment of such patients in China, and significant clinical effects have been achieved. However, to date, its efficacy has not been methodically evaluated. The purpose of this systematic review is to provide evidence to prove the effectiveness of acupuncture in the treatment of PTH in patients with TBI. ⋯ The protocol was registered in INPLASY (INPLASY 202220073).

Depletion of ovarian reserve during menopausal transition raises follicle-stimulating hormone (FSH) markedly and menopause is related to an increased risk for metabolic syndrome (MetS). This study examined the relationship between FSH and MetS in postmenopausal women. We evaluated the anthropometric values, lipid profiles, high-sensitivity C-reactive protein (hs-CRP) level, Homeostasis model assessment for insulin resistance (HOMA-IR), and serum adipokines levels in 219 postmenopausal women. ⋯ Our study showed an increased FSH level favored insulin sensitivity with a higher adiponectin and lower HOMA-IR as well as a lower incidence of MetS in postmenopausal women. These findings suggest a new approach to the role of FSH for regulating energy metabolism and for use as a biomarker of MetS risk in postmenopausal women. This systematic review is based on published researches, so there is no ethical approval required.

Effect of acupuncture on gut microbiota in participants with subjective cognitive decline.
A close relationship has recently been described between subjective cognitive decline (SCD) and gut microbiota disorders. Herein, we aim to investigate the effect of electroacupuncture (EA) on gut microbiota in participants with SCD. We conducted a study of 60 participants with SCD. ⋯ Acupuncture could improve global cognitive change among SCD participants by regulating the intestinal flora. Dysbiosis was found in the gut microbiome in SCD and partially relieved by acupuncture. Our study suggests that gut microbiota could be a potential therapeutic target and diagnostic biomarker for SCD.
