Current status and prospects of basic research and clinical application of mesenchymal stem cells in acute respiratory distress syndrome.

Acute respiratory distress syndrome (ARDS) is a common and clinically devastating disease that causes respiratory failure. Morbidity and mortality of patients in intensive care units are stubbornly high, and various complications severely affect the quality of life of survivors. The pathophysiology of ARDS includes increased alveolar-capillary membrane permeability, an influx of protein-rich pulmonary edema fluid, and surfactant dysfunction leading to severe hypoxemia.

[Effect of Doxycycline on Intrinsic Apoptosis of Myeloma Cell Line H929 and Its Mechanism].

Objective: To investigate the mechanism of the in vitro toxicity of doxycycline to myeloma cell line H929 and also the possible pathway involved its toxicity.

Methods: Myeloma cell line H929 was treated with DOX, MEK inhibitor U0126 or RAS agonist ML-098, either alone or in combination. Then, the expression of p-MEK, caspase-3, caspase-9 and c-Jun in H929 were used to detected by Western blot; the cells proliferation and apoptosis were detected by CCK-8 assay and flow cytometry, respectively.

[Factors influencing recovery from childhood inguinal herniorrhaphy-induced vas deferens obstruction after microscopic vasovasostomy].

Objective: To investigate the factors influencing the recovery from childhood inguinal herniorrhaphy (IH)-induced vas deferens obstruction following microscopic vasovasostomy.

Methods: We retrospectively analyzed the clinical data on 41 cases of microscopic vasovasostomy for obstructive azoospermia in our hospital from July 2015 to September 2018. All the patients had a history of inguinal hernia treated by IH in the childhood.

[Correlation of male libido with the levels of serum reproductive hormones].

Objective: To investigate the correlation between male libido and the levels of serum reproductive hormones.

Methods: We collected the clinical data on 134 men complaining of low or decreased sexual desire at our clinic of andrology from January 2013 to July 2018. According to the scores on the 13-item Self-Rating Libido Scale for Males (SRLS-M), we divided the subjects into a low libido (n = 68) and a normal libido group (n = 66), none with thyroid and adrenal diseases, liver and kidney diseases, or administration of drugs affecting sexual function and reproductive hormones in the past two weeks.
