ABSTRACT

Cathepsin S (CTSS) is a member of cysteine protease family. Although many studies have demonstrated the vital role of CTSS in many physiological and pathological processes including tumor growth, angiogenesis and metastasis, the function of CTSS in the development of rabbit granulosa cells (GCS) remains unknown. To address this question, we isolated rabbit GCS and explored the regulatory function of the CTSS gene in cell proliferation and apoptosis. CTSS overexpression significantly promoted the secretion of progesterone (P4) and estrogen (E2) by increasing the expression of STAR and CYP19A1 (p < 0.05). We also found that overexpression of CTSS increased GCS proliferation by up-regulating the expression of proliferation related gene (PCNA) and anti-apoptotic gene (BCL2). Cell apoptosis was markedly decreased by CTSS activation (p < 0.05). In contrast, CTSS knockdown significantly decreased the secretion of P4 and E2 and the proliferation of rabbit GCS, while increasing the apoptosis of rabbit GCS. Taken together, our results highlight the important role of CTSS in regulating hormone secretion, cell proliferation, and apoptosis in rabbit GCS. These results might provide a basis for better understanding the molecular mechanism of rabbit reproduction.

ABSTRACT

A meta-analysis was conducted to evaluate the evidence that compared the safety and efficacy of interlaminar minimally invasive discectomy (ILMI) and conventional microdiscectomy (MD) for treating lumbar disk herniation (LDH) patients and to develop GRADE based recommendations for using the procedures to treat LDH. Eleven studies, encompassing 1012 patients, met the inclusion criteria. Overall, the results of the meta-analysis indicated that there were significant differences between the two groups in blood loss (SMD=-0.93, 95% CI -1.84, -0.02; p=0.05), and the number of days stays in hospital (SMD=-0.79, 95% CI -1.55, -0.04; p=0.04). However, there were no significant differences in the short-term back visual analog scale (VAS) scores (SMD=-0.34, 95% CI -0.81, 0.14; p=0.16), the long-term back VAS scores (SMD=0.13, 95% CI -0.04, 0.30; p=0.14), the short-term leg VAS scores (SMD=0.14, 95% CI -0.01, 0.29; p=0.07), the long-term leg VAS scores (SMD=0.12, 95% CI -0.05, 0.30; p=0.17), the short-term Oswestry disability index (ODI) scores (SMD=0.01, 95% CI -0.14, 0.15; p=0.92), the long-term ODI scores (SMD=0.11, 95% CI -0.03, 0.25; p=0.14), and the incidence of complications (RR=1.22, 95% CI 0.88, 1.69; p=0.24). The results of this meta-analysis demonstrate that ILMI and MD are both safe and effective surgical procedures for treating LDH. Compared with MD, ILMI can shorten days in hospital, decrease the mounts of blood loss during surgery. However, the overall GRADE evidence quality was very low. Therefore, further validation is required, and medical institutions should conduct high-quality studies.
