With forest in the Xiangshui River sub-basin of the Liupan Mountain area as test material, we monitored sap flow in using the thermal diffusion probe during the growing season (from May 13th to September 30th) of 2022 and measured meteorological conditions and soil moisture to explore the water utilization patterns of forest under different drought types. The results showed that the piecewise linear function could accurately reflect the variation of the sap flow rate with soil relative extractable water (REW) and vapor pressure deficit (VPD). Based on the thresholds of the piecewise function, the drought conditions in this area were classified into four types: non-drought (REW≥0.

This study was conducted in Liupanshan Forest Ecological Positioning Station of the National Forestry and Grassland Administration. We monitored sap flow of plantation in the Xiangshui River sub-basin throughout the 2019 growing season (from May 17 to October 12), as well as the meteorological conditions and soil environment (soil temperature and soil water content), to analyze the comprehensive environmental responses of sap flow in under different weather conditions. The results showed that sap flow rate increased and then decreased on the daily scale, with the highest rate on sunny days, followed by overcast days and then rainy days.

Article Synopsis
  • The study investigates the relationship between hemoglobin (Hgb) levels at admission and short-term mortality in older patients with hip fractures, finding a significant link.
  • Data from 2,589 patients revealed that those with Hgb levels below 9.8 g/dL faced higher mortality risks, while levels above this threshold did not significantly impact survival.
  • The research highlighted that initial Hgb concentration is a crucial predictor of 3-year mortality in hip fracture patients, demonstrating a nonlinear relationship.

Objective: To evaluate the long-term efficacy and quality of life concerning sacrospinous ligament fixation (SSLF) using conventional instruments for Chinese women with symptomatic stage 2 and 3 apical prolapse.

Methods: This single-arm prospective cohort study was conducted at our hospital between October 2011 and December 2018. Eligible participants were followed up over 3 years after surgery.

Background: During total knee arthroplasty (TKA), surgeons mobilize the patella to facilitate clear visualization of the articular surfaces and allow better prosthesis placement. According to the manipulation, this manipulation can be divided into patellar eversion and noneversion. However, the effect of patellar eversion in TKA is controversial, with substantial variability in clinical practice.

Aim: To investigate the changes in type II neuregulin-1 (NRG-1) during the regeneration process following autologous sciatic nerve transplantation in rats.

Material And Methods: In total, 40 healthy male Sprague-Dawley (SD) rats of clean grade with body weights between 250 g and 300 g were randomly divided into an experimental and control group, with 20 rats per group. Five time points were set, including the 3 < sup > rd < /sup > , 7 < sup > th < /sup > , 14 < sup > th < /sup > , 21 < sup > st < /sup > and 28 < sup > th < /sup > days after surgery.

Objective: Adding vitamin E to highly cross-linked polyethylene liners is frequently performed in clinical practice, aiming at reducing liner wear, increasing liner survival, and delaying revision surgery. This study is aimed at evaluating the revision rate, total femoral head penetration, and postoperative clinical function of highly cross-linked polyethylene liners with and without vitamin E in total hip arthroplasty.

Methods: We conducted a systematic literature search to identify the use of highly cross-linked vitamin E liners compared to other liners in patients who received total hip arthroplasty (THA) before April 2021.

Article Synopsis
  • The study investigates how environmental factors like meteorological conditions, soil water content, and canopy structure affect tree sap flow in a specific area of the Liupan Mountains from June to September 2019.
  • Researchers found that the sap flow rate is influenced by potential evapotranspiration (PET), relative extract water (REW), and canopy leaf area index (LAI) in varying degrees, leading to different response patterns for each factor.
  • A model was developed to predict sap flow by considering the interactions among PET, REW, and LAI, revealing that PET is the most significant factor, particularly varying greatly between sunny, cloudy, and rainy days.

Ganoderic acid A (GA) is one of the most abundant triterpenoids in Ganoderma lucidum, and has been proved to possess a wide range of beneficial health effects. The aim of the current study is to investigate the amelioration effects and mechanism of GA on improving hyperlipidemia in mice fed a high-fat diet (HFD). The results showed that GA intervention significantly inhibited the abnormal growth of body weight and epididymal white adipose tissue (eWAT), prevented the hypertrophy of epididymal adipocytes, and ameliorated the biochemical parameters of serum and liver related to lipid metabolism in HFD-fed mice.

Background: Alendronate has been used to prevent or treat glucocorticoid-induced osteoporosis (GIO), data regarding its efficacy are inconsistent. We conducted the current systematic review and meta-analysis to evaluate both efficacy and safety of alendronate in the treatment of GIO.

Methods: PubMed, Embase, the Cochrane Controlled Trials Registry, and the China Academic Journal Network Publishing Databases were searched up through March 1, 2018.

Objectives: Osteoporosis remains a clinical challenge. Teriparatide is an anabolic drug and alendronate is an antiresorptive agent; both are used in the treatment of osteoporosis. Comprehensive reviews investigating the comparative safety and efficacy of teriparatide versus alendronate are scarce.

Lignocellulosic material is the most abundant renewable resource in the earth. Herbivores and wood-eating insects are highly effective in the digestion of plant cellulose, while anaerobic digestion process simulating animal alimentary tract still remains inefficient. The digestion mechanisms of herbivores and wood-eating insects and the development of anaerobic digestion processes of lignocellulose were reviewed for better understanding of animal digestion mechanisms and their application in design and operation of the anaerobic digestion reactor.
