High mobility group A2 protein (HMGA2), an architectural factor, is highly expressed in various cancer types including lung cancers. It is a candidate target for cancer therapy. RNAi is an effective gene silencing method with low cost and less time-consuming. It is possible to exploit this technology in therapy. Here, 5 siRNAs targeting Hmga2 gene (HMGA2 siRNA1-5) were designed and synthesized. MTT assay, colony formation assay, transwell assay and flow cytometry were used to evaluate the effects of these siRNAs on lung cancer cell lines (NCI-H446 and A549). Results from cell proliferation, clone formation, migration and apoptosis showed that HMGA2 siRNA1, 3, 5 could affect these aspects for both lung cancer cell lines. Among the five siRNAs, HMGA2 siRNA5 showed the greatest inhibition effects. The inhibition effects of HMGA2 siRNA5 are sequence specific and are not due to the induction of interferon response. Taken together, siRNAs targeting Hmga2 gene are potential candidates for lung cancer gene therapy.

OBJEVTIVETo analyze the complications of extracorporeal shock wave lithotripsy (ESWL) for treatment of lower urinary tract stones and identify the factors contributing to the complications.
METHODSWe retrospectively analyzed the postoperative complications of ESWL in 83 patients with lower urinary tract stones and their association with the patients' age, height, body weight, body mass index (BMI), stone features, shock wave times, and shock wave energy.
RESULTSOf the 83 cases treated with ESWL, 72.3% (60 cases) showed gross hematuria, 27.7% (23 cases) complained of pain, and 25.3% (21 cases) had both pain and gross hematuria. None of the patients reported vomiting, skin rash, flatulence, gastrointestinal bleeding or other complications. Patients with postoperative gross hematuria, pain, and both had significantly greater stone length, stone width and more shock body times than those without these complications (P<0.01 or P<0.05). Patients with gross hematuria had significantly lower height than those without complications (P<0.05).
CONCLUSIONThe common complications of ESWL for lower urinary tract stones include hematuria and pain. The patient's height, stone length, stone width and shock times are important factors contributing to these postoperative complications.

Objective To investigate the role of vitamin D in the synthesis and degradation of aggrecan in rat articular chondrocytes at cellular level. Methods Rat articular chondrocytes were stimulated by IL-1α, IL-1β and TNF-α, respectively. Normal and inflammatory chondrocytes were treated with different doses of vitamin D, respectively. CCK8, Flow cytometry, real time-PCR and western blot analysis were used to examine the proliferation activity and apoptosis level of chondrocytes, and the expression of aggrecan, ADAMTS-4 and ADAMTS-5 at both mRNA and protein levels. Results IL-1α,IL-1β and TNF-α significantly decreased the proliferation activity and increased the apoptosis level of the chondrocytes. Furthermore, IL-1α, IL-1β and TNF-α significantly decreased the expression of aggrecan, and increased the expressions of ADAMTS-4 and ADAMTS-5 at both mRNA and protein levels in the chondrocytes. 1α,25 (OH)2D3supplementation significantly increased the proliferation activity and decreased the apoptosis level of chondrocytes stimulated by IL-1α, IL-1β and TNF-α in a dose-dependent manner, but not affected the normal chondrocytes. Meanwhile, 1α,25(OH)2D3also significantly increased the expression of aggrecan, and decreased the expressions of ADAMTS-4 and ADAMTS-5 at both mRNA and protein levels in the chondrocytes under inflammatory conditions. Conclusions Vitamin D may promote the anabolism of aggrecan and inhibit aggrecanase activity in chondrocytes under inflammatory conditions, which may impact overall protection for articular cartilage.

OBJEVTIVETo investigate the expression of cysteine-rich secretory protein 2 (CRISP2) in spermatozoa of patients with asthenozoospermia and explore its clinical significance.
METHOSSemen samples were collected from 24 normal volunteers and 24 patients with asthenozoospermia for detecting CRISP2 mRNA and protein expressions using qRT-PCR and Western blotting, respectively. The correlation of CRISP2 expressions with sperm morphology, progressive motility and fertility prognosis were analyzed in patients with asthenozoospermia.
RESULTSCRISP2 protein expression was obviously lowered in the ejaculated spermatozoa of patients with asthenozoospermia as compared to the normal volunteers, but no significant difference in CRISP2 mRNA expression was found between the two groups. Correlation analysis showed that CRISP2 protein expression was positively correlated with normal sperm morphology (r=0.6182, P=0.0037) and progressive motility (r=0.6309, P=0.0029). Follow-up study of the patients revealed a higher fertility rate in patients with a relatively high CRISP2 protein expression than in those with low CRISP2 protein expression (80.0% vs 20.0%, P=0.0230).
CONCLUSIONThe expression level of CRISP2 protein is positively correlated with normal sperm morphology and progressive motility. A reduced CRISP2 protein expression indicates poor fertility prognosis of patients with asthenozoospermia, suggesting the potential value of CRISP2 as a novel therapeutic target for treating asthenozoospermia.

ObjectiveTo explore the effects of Naozhenning granules on the memory function and neuron cells in the rat model of post-concussion syndrome based on mitochondrial biosynthesis. MethodSPF-grade Wistar rats were used to establish the multiple cerebral concussion (MCC) model by the weight-drop method. The successfully modeled rats were assigned into model, piracetam (0.324 g·kg-1), and low-, medium-, and high-dose (2.25, 4.5, and 9 g·kg-1, respectively) Naozhenning groups. The rats were administrated with corresponding drugs by gavage and those in the blank group and model group were administrated the same volume of normal saline once a day for 14 days. The general state of rats was observed before and after treatment. The open field test and new object recognition test were conducted to examine the motor and memory abilities of rats. Hematoxylin-eosin staining was employed to observe the pathological changes of cortical neurons in rats. Western blot and real-time polymerase chain reaction were employed to determine the protein and mRNA levels, respectively, of peroxisome proliferator-activated receptor γ-coactivator-1α (PGC-1α), nuclear respiratory factor-1 (NRF-1), and transcription factor A mitochondrial (TFAM) in rat cortex. ResultCompared with the blank group, the model group showed anxious and manic mental status, yellow and messy fur, and reduced food intake. In the open field experiment, the model group showed reduced total movement distance, times of entering the central grid, and times of rearing decreased and increased resting time compared with the blank group (P<0.01). The model group had lower recognition index of new objects than the blank group (P<0.01). In addition, the modeling caused reduced neurons with sparse distribution and deformed, broken, and irregular nucleoli and down-regulated the mRNA and protein levels of PGC-1α, NRF-1, and TFAM in the cortex (P<0.01). Compared with the model group, piracetam and Naozhenning improved the mental state, coat color, food intake, and activities of rats. In the open field test, piracetam and Naozhenning increased the total movement distance, the times of entering the central grid, and the times of rearing and shortened the resting time (P<0.05, P<0.01). The piracetam and Naozhenning groups had higher recognition index of new objects than the model group (P<0.05, P<0.01). Compared with the model group, the piracetam and Naozhenning groups showed increased neurons with tight arrangement and large and round nuclei, and some cells with irregular morphology and turbid cytoplasm. Furthermore, piracetam and medium-dose Naozhenning upregulated the protein levels of PGC-1α, NRF-1, and TFAM (P<0.01). Low-dose Naozhenning upregulated the protein levels of NRF-1 and TFAM (P<0.01), and high-dose Naozhenning upregulated the protein levels of PGC-1α and TFAM in the cortex (P<0.01). The mRNA levels of PGC-1α, NRF-1, and TFAM in the cortex were upregulated in the piracetam group and Naozhenning groups (P<0.05, P<0.01). ConclusionNaozhenning granules can improve the motor, memory, and learning, repair the neuronal damage, and protect the nerve function in the rat model of MCC by promoting mitochondrial biosynthesis.

OBJECTIVETo investigate the protective effect of bone marrow mesenchymal stem cells (BMSCs)-derived exosomesagainst testicular ischemia-reperfusion injury (IRI) in rats.
METHODSRat BMSCs were isolated, cultured and identified in theprimary culture. The exosomes were extracted from the BMSCs and characterized using nanoparticle tracking analysis, transmission electron microscopy, and Western blotting. Twenty-four healthy male SD rats were randomly divided into shamoperation group, testicular IRI with saline treatment group and IRI with exosome treatment group. The contralateral testes ofthe rats were collected for pathological observation, aseessment of superoxide dismutase (SOD) and malondialdehyde (MDA), and detection of HMGB1, caspases-3 and cleaved caspase-3 expressions using Western blotting.
RESULTSWe successfullyobtained exosomes from rat BMSCs. Testicular IRI significantly impaired testicular spermatogenesis, which was markedlyimproved by treatment with the exosomes ( < 0.05). Testicular IRI also caused significant increase in the protein expression ofHMGB1, caspase-3 and cleaved caspase-3 in the testicular tissue, and treatment with the exosomes obviously amelioratedthese changes ( < 0.05).
CONCLUSIONSBMSCs-derived exosomes protects against testicular IRI due to the anti-oxidant, antiinflammatory and anti-apoptosis activities of the exosomes.
