Relationships among vegetation restoration, drought and hydropower generation in the karst and non-karst regions of Southwest China over the past two decades.

To curb the intensification of desertification, China has implemented a series of measures to control rocky desertification. However, the interaction between vegetation restoration and the frequent occurrence of extreme weather events has complicated the drought situation in Southwest China. Therefore, in this study, the vegetation health index (VHI) was used to analyze the spatiotemporal variations in drought.

Breast-Feeding is Not a Risk Factor of Mother-to-Child Transmission of Hepatitis B Virus.

Purpose: This study aims at researching the content of hepatitis B virus (HBV) DNA in the breast milk of the mothers carrying HBV and investigating the effects of different feeding methods on mother-to-child transmission (MTCT) of HBV.

Methods: All infants were voluntarily chosen by their mothers and divided into breast-feeding group and formula-feeding group, which were divided into three subgroups, respectively: HBV-DNA negative (HBV-) group, low viral load (LVL) group and high viral load (HVL) group.

Results: HBV load in colostrum and mature milk were both significantly lower than in serum (P < 0.

Expression of polymeric immunoglobulin receptor and its biological function in endometrial adenocarcinoma.

Aim: To investigate the expression of polymeric immunoglobulin receptor (pIgR) in endometrial adenocarcinoma and the relationship between pIgR and the clinicopathological features of endometrial adenocarcinoma. To investigate the role of pIgR in the biological behavior of endometrial adenocarcinoma cell lines.

Methods: First, the paraffin-embedded endometrial adenocarcinoma samples and clinicopathological data from the Chao-Yang Hospital were collected.

Kissing nevus of the penis. Report of two cases and review of the literature.

Kissing nevus is a curious type of nevus that was first described on the eyelids and rarely described on the penis. We report two cases of kissing nevus of the penis and review previously reported cases. The lesions of the kissing nevus of the penis showed characteristic mirror-image symmetry relative to the coronal sulcus.

Cartilage tissue engineering using PHBV and PHBV/Bioglass scaffolds.

Scaffolds have an important role in cartilage tissue engineering. Poly(hydroxybutyrate‑co‑hydroxyvalerate) (PHBV) has been demonstrated to have potential as a scaffold for the three dimensional construction of engineered cartilage tissue. However, the poor hydrophilicity and mechanical strength associated with PHBV affects its clinical applications as a scaffold in cartilage tissue engineering.

Frontalis muscle flap advancement for correction of severe ptosis under general anesthesia: modified surgical design with 162 cases in China.

Background: Congenital blepharoptosis is a common pediatric disease. Frontalis muscle flap advancement is an effective surgical technique to treat patients with severe ptosis and poor levator function. However, since eye position changes under general anesthesia, it is necessary to adjust the position of the upper eyelid to achieve a better surgical outcome.

A surface plasmon resonance-based system to genotype human papillomavirus.

We report a novel system (W2600) that is based on the technology of surface plasmon resonance (SPR) to genotype human papillomavirus (HPV). The system permitted detection of 24 known HPV genotypes, including 16 high-risk types (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 81) and 8 low-risk types (HPV 6, 11, 40, 42, 43, 44, 54, 70). Analytical performance of W2600 for HPV genotyping was evaluated by HPV DNA derived from the liquid cervical cytology specimens of 560 patients with atypical squamous cells of undetermined significance or above.
