Efficacy and safety of oral and vaginal administration of misoprostol for induction of labor in high-risk obese pregnant women with hypertension or diabetes mellitus.

Objective: This study aims to compare the safety and efficacy of misoprostol administered orally and vaginally in obese pregnant women at term with either gestational hypertension or diabetes.

Methods: A total of 264 pregnant women were enrolled and categorized into two groups based on their primary condition: hypertension (134 cases) or diabetes mellitus (130 cases) and were further divided into subgroups for misoprostol administration: orally (Oral group) or vaginally (Vaginal group). The primary outcomes measured were changes in the Bishop score following treatment, induction of labor (IOL) success rates, requirement for oxytocin augmentation, duration of labor, mode of delivery, and cesarean section rates.

Patient-controlled intravenous administration of dexmedetomidine with nalbuphine versus sufentanil for post cesarean delivery analgesia: A retrospective observational study.

This retrospective observational study aims to investigate the patient-controlled intravenous analgesia (PCIA) of dexmedetomidine (DEX) with nalbuphine (NAL) versus sufentanil (SUF) for post-cesarean delivery management. A total of 300 women were evaluated who underwent cesarean section surgery with combined spinal-epidural anesthesia. After surgery, all patients were connected to a patient-controlled analgesia pump.

A Systematic Method for the Identification of Aporphine Alkaloid Constituents in Sabia schumanniana Diels Using UHPLC-Q-Exactive Orbitrap/Mass Spectrometry.

Diels (SSD) is a plant whose stems are used in traditional folk medicine for the treatment of lumbago and arthralgia. Previous studies have revealed chemical constituents of SSD, including triterpenoids and aporphine alkaloids. Aporphine alkaloids contain a variety of active components, which might facilitate the effective treatment of lumbago and arthralgia.

Expression Plasticity of Transposable Elements Is Highly Associated with Organismal Re-adaptation to Ancestral Environments.

Understanding the roles of phenotypic plasticity in adaptive evolution has gained recognition for decades. Studies involving multiple taxa have shown that gene expression plasticity serves as "long-term memory" to facilitate re-adaptations to ancestral environments. Nevertheless, the general pattern and the underlying genetic basis of expression plasticity remain unclear.

DNA methylation in polycystic ovary syndrome: Emerging evidence and challenges.

Polycystic ovary syndrome (PCOS) is a disease related to reproductive endocrine abnormalities in women of reproductive age, often accompanied by metabolic diseases such as hyperandrogenemia, insulin resistance and dyslipidemia. However, the etiology and mechanism of PCOS are still unclear. In recent years, more and more studies have found that epigenetic factors play an important role in PCOS.

Clinical features and risk factors associated with severe COVID-19 patients in China.

Background: Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout the world. In this study, we aimed to identify the risk factors for severe COVID-19 to improve treatment guidelines.

Methods: A multicenter, cross-sectional study was conducted on 313 patients hospitalized with COVID-19.

Sweet Solutions for Analgesia in Neonates in China: A Systematic Review and Meta-Analysis.

Introduction: High-quality synthesized evidence of sweet taste analgesia in neonates exists. However, Chinese databases have never been included in previous systematic reviews of sweet solutions for procedural pain.

Objective: To conduct a systematic review of Chinese literature evaluating analgesic effects of sweet solutions for neonates.

Myocardial injury in elderly patients after abdominal surgery.

Background: The development of sensitive myocardial-specific cardiac biomarkers allows for detection of very small amounts of myocardial injury or necrosis. Myocardial injury (MI) as a prelude of the serious perioperative complication myocardial infarction, should be paid more attention, especially in elderly susceptible patients. Myocardial injury after abdominal surgery in elderly patients has not been described yet.

Impatiens pandurata (Balsaminaceae), a new species from Yunnan, China.

Background: The species-rich genus Impatiens is mainly distributed throughout much of tropical Africa, India, southwest Asia, southern China and Japan. There are more than 270 species recorded in China, most of which are restricted to the southwest. An unknown species of Impatiens was collected from Yunnan, southwest China.

CXCL12/CXCR4 chemokine signaling in spinal glia induces pain hypersensitivity through MAPKs-mediated neuroinflammation in bone cancer rats.

The activation of MAPK pathways in spinal cord and subsequent production of proinflammatory cytokines in glial cells contribute to the development of spinal central sensitization, the basic mechanism underlying bone cancer pain (BCP). Our previous study showed that spinal CXCL12 from astrocytes mediates BCP generation by binding to CXCR4 in both astrocyters and microglia. Here, we verified that CXCL12/CXCR4 signaling contributed to BCP through a MAPK-mediated mechanism.

CXCL12 in astrocytes contributes to bone cancer pain through CXCR4-mediated neuronal sensitization and glial activation in rat spinal cord.

Background: Previous studies have demonstrated that chemokine CXCL12 and its receptor CXCR4 are critical for pain sensitization, but the mechanisms involved are not clear. In this study, we investigated the specific cellular mechanisms of CXCL12/CXCR4 chemokine signaling in the development and maintenance of bone cancer pain after tumor cell implantation (TCI).

Methods: TCI in the tibial cavity of rats was used to establish a bone cancer pain model.

Simultaneous improvement of mechanical properties and thermal stability of bacterial polyester by cellulose nanocrystals.

Green nanocomposites were prepared by adding well-dispersed cellulose nanocrystals (CNCs) into bacterial polyester poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) matrix. Simultaneous enhancements on the mechanical property and thermal stability of PHBV after reinforcement of CNCs were achieved. Compared to neat PHBV, a 149% improvement in tensile strength and 250% increase in Young's modulus can be obtained for the resulting nanocomposites with 10 wt.

The impact of PET/CT on therapeutic strategy of patients with colorectal cancer metastasis.

Background/aims: The study's aim was to assess the impact of the PET/CT on the therapeutic strategy of the patients with colorectal cancer metastasis.

Methodology: Fifteen patients who were suspicious of postoperative colorectal cancer metastasis were included in the study. Each patient received a positron emission tomography/computed tomography (PET/CT) after received contrast-enhanced computed tomography (ceCT).

[Surface-enhanced Raman spectra of natural tissue and cancerous tissue of lung].

Surface-enhanced Raman spectra of natural tissue and cancerous tissue of lung from 300 to 1700 cm(-1) were measured. In the cancerous tissue of lung, the orderly conformations of amides III and amides I of the main chains in protein such as alpha-helix, beta-corner and no rules curly were damaged seriously; conversely, the extendable vibration of skeleton C-N and skeleton C-C increased. Side chains change became complicated.

[Surface-enhanced Raman spectra of oxidation damnification of fetal bovine serum by ozone].

Fetal bovine serum was treated by ozone for 1 hour and 3 hours before getting its surface-enhanced Raman spectra from 200 to 1 800 cm(-1). Treated with ozone for 1 hour, it shows a significant decrease in band intensity. Treated with ozone for 3 hours, the band intensity has a further decrease but not so obviously, which means that oxidation of ozone is short lived.

Regulatory mechanisms controlling human E-cadherin gene expression.

In cancer cells, loss of E-cadherin gene expression caused dysfunction of the cell-cell junction system, triggering cancer invasion and metastasis. Therefore, E-cadherin is an important tumor-suppressor gene. To understand how E-cadherin gene expression is regulated in cancer cells, we have used E-cadherin-positive and -negative expressing cells to find out the possible up- or down regulating transcription factors in human E-cadherin regulatory sequences.
