Effects of climate warming and declining water quality on the eco-environmental evolution of Jinmucuo Lake: Evidence from sedimentary diatom assemblages.

The problem of lake pollution on the Tibetan Plateau has become prominent in recent years because of the warming climate and increased human activity. However, it is difficult to obtain effective indicators to explain the long-term eco-environmental changes in plateau lakes. In this study, a sediment core from Jinmucuo Lake was taken as the research object, and the Pb and Cs isotopes, diatom assemblages, and climatic and environmental factors were analyzed.

Can laparoscopic nerve-sparing ultra-radical hysterectomy play a role in locally advanced cervical cancer? A single-center retrospective study.

Background And Objectives: The objective of this study is to investigate the outcomes of concurrent platinum-based chemoradiation therapy (CCRT), laparoscopic nerve-sparing ultra-radical hysterectomy (LNSURH), and open radical hysterectomy (ORH) on patients with locally advanced cervical carcinoma (LACC).

Methods: A single-center retrospective study was conducted on LACC patients who received CCRT, ORH, or LNSURH from January 2011 to December 2019. Data on age, tumor size, overall survival (OS), disease-free survival (DFS), and early and late morbidities were collected.

Survival Impacts of Perineural Invasion on Patients Under Different Radical Hysterectomies Due to Early Cervical Cancer.

Objective: Cervical cancer is a common gynecological malignancy. In addition to the open radical hysterectomy (ORH) and laparoscopic radical hysterectomy (LRH), laparoscopic nerve-sparing radical hysterectomy (LNSRH) could be another treatment option since it could preserve urinary, colorectal, and sexual functions. However, LNSRH might result in early cancer metastasis and recurrence due to inadequate tumor resection.

Efficacy of laparoscopic sleeve gastrectomy in obese patients with type 2 diabetes mellitus: A protocol of systematic review and meta-analysis.

Background: A numerous studies have reported that obese patients (OP) are easily to have type 2 diabetes mellitus (T2DM). Although a variety of managements are available to treat such disorder, their efficacy is still limited. Previous studies have reported that laparoscopic sleeve gastrectomy (LSGT) can benefit OP with T2DM.

A proposed delineation method for lake buffer zones in watersheds dominated by non-point source pollution.

Although buffer zones around aquatic areas are a useful method for controlling non-point source pollution and restoring natural ecosystem services, proper delineation methods for lakes remain poorly defined, restricting their protection and the rational utilization of resources. As the width of lake buffer zones should be set to meet the area's functional targets and requirements, this study proposes a methodology for delineating these zones that includes critical source areas for non-point source pollution and ecologically sensitive areas. The proposed method was tested on Zhushan Bay, Lake Tai, China given its poor environmental condition and a renewed focus on mitigation by the local government.

Wetland ecosystem status and restoration using the Ecopath with Ecosim (EWE) model.

With increasing awareness of the importance of wetlands, the number of new or restored wetlands in China is steadily growing; however, not all of them fulfill their expected ecological function. Maintaining wetlands in their optimal state is an urgent problem that requires research into the ecosystem evaluation, regulation, and biomass management of wetlands. The Ecopath with Ecosim (EWE) model, also known as the ecological channel model, is a balance model that can directly construct the ecological system structure and describe its energy flow and mass transfer through the principle of nutrition dynamics.

[Preliminary study on pathogen of Whitmania pigra disease in high temperature environment].

In this paper, on the contrast of healthy leech, the bacterial diversities were analyzed by 16S rDNA sequence analysis of the bacteria of muscle and intestinal tract of Whitmania pigra, the environment water and sediment of cultivating the diseased Wh. pigra in high temperature by high-throughput sequencing to determine the possible pathogenic bacteria of bacterial diseases of Leech in high temperature. The results showed that the original sequence reached over 83 000, and the effective sequences accounted for more than 87%.

[Effects of Different Pretreatment Methods on the Phenylketonuria Screening Model by FTIR/ATR Spectroscopy].

To establish a phenylketonuria screening model by FTIR/ATR spectroscopy, and to compare the effects of different pretreatment methods, such as baseline correction, smoothing, derivation, Fourier deconvolution, on the model quality. A consensus partial least squares regression method (cPLS) was used to build the quantitative model of phenylalanine in dried blood spots. The effects of different pretreatment methods on the model performance were investigated, using the correlation coefficient (r), root mean square error of prediction (RMSEP), mean relative error (MRE) and predictive accuracy (Acc).

[Effect of closed high-pressure suction drainage on primary healing of perineal wound after abdominoperineal resection for rectal cancer].

Objective: To evaluate the impact of closed high-pressure suction drainage on the healing of the perineal wound after abdominoperineal resection.

Methods: Patients undergoing rectal abdominoperineal resection in the Wuhan Tongji Hospital from January 2009 to January 2011 were randomized into two groups including the study group(n=61, closed high-pressure suction drainage) and the control group(n=59, presacral drainage). The drainage volume, primary healing rate, and the healing time of perineal wounds were compared.

EPO improves the proliferation and inhibits apoptosis of trophoblast and decidual stromal cells through activating STAT-5 and inactivating p38 signal in human early pregnancy.

The erythropoietin (EPO) belongs to the family of angiogenic factors, which is regulated by Hypoxia-inducible factor- 1α (HIF-1α). As known, EPO are expressed in human villi and decidua, but the function is not clear. In this study, we investigated the expression and roles of HIF-1α, EPO and its receptor (EPOR) in the biological functions of trophoblast and decidual stromal cell (DSC) in human early pregnancy.
