OBJECTIVETo investigate the influence of the rate of morphologically normal sperm (MNS) on the clinical outcomes of conventional in vitro fertilization (IVF) in patients with one retrieved oocyte.
METHODSFrom January 2013 to January 2015, a total of 256 couples with one retrieved oocyte underwent conventional IVF in our center. According to the rate of MNS, the patients were divided into two groups: MNS < 4% (134 cycles) and MNS ≥ 4% (122 cycles). We compared the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo between the two groups. A total of 75 fresh embryo transfer cycles were performed, 43 in the MNS < 4% group and the other 32 in the MNS ≥ 4% group. We also compared the rates of implantation, clinical pregnancy and abortion between the two groups.
RESULTSThere were no statistically significant differences between the two groups in the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo (P > 0.05). The rates of implantation, clinical pregnancy and abortion exhibited no remarkable differences either in the fresh embryo transfer cycles between the two groups (P > 0.05).
CONCLUSIONThe rate of MNS does not affect the clinical outcomes of conventional IVF in patients with one retrieved oocyte.

Reactive oxygen species (ROS) is a kind of molecules derived by oxygen in the metabolic process of aerobic cells, which mainly includes superoxide, hydroxyl radicals, alkoxyl, hydrogen peroxide, hypochlorous acid, ozone, etc. They can destroy the structure and function of cells through the damage of biological macromolecules such as DNA, proteins and the lipid peroxidation. ROS also can regulate the proliferation, differentiation and apoptosis of cells through several signaling pathways and participate in fibrogenesis of many organs including hepatic and pulmonary fibrosis. Recent study shows that ROS might have an important effect on the forming of myelofibrosis. Consequently, ROS plays a significant role in the fibrogenesis of tissues and organs. In this review, the relevance between ROS and common tissues and organs fibrosis is summarized.

Objective To explore the mechanism of Niaochangshu capsule in the treatment of postmenopausal overactive bladder, through observing its influence on bladder weight and the expression of eNOS and AQP1 of ovariectomized female rats. Methods Female SD rats were divided into blank group, model group, Nilestriol group and Niaochangshu group. Rats were removed ovaries except the blank group. The treatment groups were given corresponding drugs, blank group and model group were given normal saline by gavage. After 4 weeks, the bladders' weight and thickness were detected, the expressions of eNOS and AQP1 in serum and bladder tissue were determined by ELISA, and NO by spectrophotometry. Results Ovariectomy resulted in decreased bladder weight, bladder mucosal and muscular atrophy, and opposite changes showed after given Niaochangshu. The expressions of eNOS and NO in bladder and serum were decreased significantly after ovariectomy, while increased by given Niaochangshu capsule or nylestriol (P<0.05), and there was significant difference between Niaochangshu group and Nilestriol group (P<0.05). The expression of AQP1 was decreased in the model group, and increased after given nylestriol or Niaochangshu capsule. While the expression of AQP1 in bladder had no significant difference among the four groups. Conclusion Niaochangshu capsule can reverse bladder mucosal and muscular atrophy caused by estrogen deficiency, and increase the content of eNOS in serum and bladder, thus play the role in the treatment of postmenopausal overactive bladder.

OBJECTIVE:
To investigate osteopontin (OPN) expression in plasma and tissue of patients with layngeal squamous cell carcinoma and analyze its role in invasion, metastasis, and clinical significance in laryngeal quamous cell carcinoma.
METHOD:
Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry were used to detect expression of OPN in plasma and tissue of 60 cases of laryngeal squamous cell carcinoma, 20 cases of adjacent normal laryngeal tissue and 20 cases of plasma from healthy subjects.
RESULT:
The expression of plasma OPN was closely correlated with clinical stage and cervical lymphatic metastasis in laryngeal squamous cell carcinoma (P < 0.05), but no significant correlation with the tumor location, pathological grade, gender and age (P > 0.05). The expression of OPN increased in plasma during cancer development: laryngeal squamous cell carcinoma (38.089 ± 9.225) ng/ml, healthy subjects (18.563 ± 9.308) ng/ml. There was a significant difference between the groups (P < 0.05). The expression of OPN in tissue was closely correlated with clinical stage (P < 0.05), pathological grade (P < 0.05) and cervical lymphatic metastasis (P < 0.05) in laryngeal squamous cell carcinoma adjacent atypical hyperplastic epithelium and carcinoma. The expression of OPN increased in tissue during cancer development: laryngeal squamous cell carcinoma (56.67%), adjacent normal laryngeal tissue (15.00%). There was a significant difference between the groups (P < 0.05). Elevated expression of plasma OPN is positively correlated with the expression of OPN in tissue in laryngeal squamous cell carcinoma patients (r = 0. 871, P < 0.05).
CONCLUSION
OPN plays an important role in the infiltration, metastasis and carcinogenesis in laryngeal squamous cell carcinoma. Combination of serum OPN, tissue OPN detection can be used as diagnostic and surveillance indicators for laryngeal squamous cell carcinoma infiltration and metastasis.
