ABSTRACT

OBJECTIVE@#To explore the therapeutic effect of multiple small diameter drilling combined with extracorporeal shock wave therapy (ESWT) under C-arm X-raylocalization in patients with early osteonecrosis of the femoral head (ONFH).@*METHODS@#A total of 106 cases of early ONFH patients admitted from May 2015 to May 2017 were retrospectively selected as the study subjects. According to different treatment methods, the patients were divided into observation group and control group, 53 cases in each group. The observation group was treated with multiple small-diameter drilling combined with ESWT under C-arm positioning in the observation group, including 41 males and 12 females with an age of (45.85±6.01) years old (22 to 70 years old);and the control group was treated with ESWT, including 34 males and 19 females with an age of (45.12±5.83) years old(20 to 68 years old) in the control group. The modified Harris hip scores(mHHS), visual analog scale(VAS), hip flexion range, hip abduction and adduction range, ONFH area ratio and clinical efficacy were compared between twe groups before and after treatment. Kaplan-Meier method was used to draw a survival curve to compare the femoral head survival rate between two groups during the 3-year follow-up period after treatment.@*RESULTS@#There were no complications such as poor wound healing and infection. All of 106 patients were followed up for 28 to 36 months with an average of (31.06±4.28) months. MHHS score, hip flexion range and hip abduction and adduction range in the observation group were increased from (63.85±5.42) scores, (23.79±2.21) °, (32.40±4.19) ° before treatment to (85.51±5.69) scores, (34.65±2.73)°, (43.32±5.71)° at 2 years after treatment, respectively(P<0.05). The above indicators in the control group increased from (64.73±5.64)°, (23.82±2.18)°, (32.45±4.13)° before treatment to (81.65±5.48) scores, (32.79±2.87)°, (39.75±5.68)°at two years after treatment, respectively(P<0.05). VAS score and ONFH area ratio in the observation group decreased from (5.76±1.41) scores and (35.07±4.96)% before treatment to (3.39±1.02) scores and (22.04±3.23)% at 2 years after treatment, respectively(P<0.05). The above indicatiors in control group decreased from (5.73±1.45) scores and (35.24±5.18)% before treatment to (4.43±1.21) scores and (28.32±3.76)% at 2 years after treatment, respectively(P<0.05), and the improvement in the observation group was significantly higher than that in the control group(P<0.05). At 3 years after treatment, the femoral head survival rate in the observation group was higher than that in the control group (P<0.05).@*CONCLUSION@#Multiple small diameter drilling combined with ESWT under C-arm positioning can significantly improve the clinical symptoms of patients with early ONFH, relieve pain and improve clinical efficacy.

ABSTRACT

OBJECTIVE@#To investigate the molecular mechanism by which miR-20a-5p regulates HOXB13 gene expression and inhibits lung cancer cell proliferation.@*METHODS@#The expression levels of HOXB13 mRNA and protein in lung cancer A549 cells transfected with HOXB13 overexpression plasmid or HOXB13 siRNA were detected with real-time fluorescence quantitative PCR (qRT-PCR) and Western blotting. CCK-8 and EdU assays were used to examine the effect of modulation of HOXB13 expression on cell proliferation. We screened possible binding miRNAs of HOXB13 by bioinformatics analysis. In A549 cells transfected with miR-20a-5p mimic or miR-20a-5p inhibitor, the expression level of miR-20a-5p was detected by qRT-PCR and the protein expression of HOXB13 was determined with Western blotting. CCK-8 and EdU assays were used to assess the effect of miR-20a-5p overexpression on the proliferation of A549 cells. miR-20a-5p mimic and HOXB13 overexpression plasmids were co-transfected into A549 cells, and the changes in cell proliferation were evaluated with CCK-8 and EdU assays.@*RESULTS@#HOXB13 overexpression obviously promoted the proliferation of A549 cells (P < 0.05). miR-20a-5p was identified as the potential binding miRNA of HOXB13. Overexpression of miR-20a-5p in A549 cells significantly decreased the expression of HOXB13 protein (P < 0.05), while interference of miR-20a-5p obviously increased HOXB13 expression (P < 0.05). The results of cell proliferation experiment showed that miR-20a-5p and HOXB13 had opposite effects on cell proliferation, and the cells overexpressing both miR-20a-5p and HOXB13 showed a lower proliferation activity than the cells overexpressing HOXB13 but higher than the cells overexpressing miR-20a-5p alone (P < 0.05).@*CONCLUSION@#miR-20a-5p inhibits proliferation of lung cancer cells by down-regulating the expression of HOXB13.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a common illness of respiratory system, seriously threatening human life and health. Emergence and development of COPD are results of inter-actions between genes and pathogenic factors. The combination of cigarette smoking exposure and genetically engineered mice is able to make similar biological effects of special genes under pathogenic condition of cigarette smoke exposure. The article summarizes the method practice on study of drug targets, inflammation and immune in COPD, analyzes the results of these studies, and describes the basic process of the method, aiming to provide reference for research on pathogenesis and drugs of COPD.

ABSTRACT

Objective To observe the effect of β-carotene ( β-C ) on the learning and memory and the expression of caspase-3 and p-tau expression in hippocampus of obstructive sleep apnea syndrome ( OSAS) rats. Methods Twenty-four adult SD rats were randomly divided into normal control group, OSAS model group ( model group) and β-C intervention group (intervention group), with 8 rats in each group. A hypoxic chamber was used to establish an OSAS rat animal model. The rats in model group and intervention group were given by gavage before intragastric administration, and no treatment was performed in the normal group. After completion of the modeling, the Morris water maze was used to test the learning and memory ability of the experimental rats. Observing the pathological changes of hippocampal tissue in rats by HE staining. The protein expression of caspase-3 and p-tau in hippocampus was detected by Western Blotting. Results Escape latency time of model group in each time point were significantly prolonged than those in normal control group ( all P<0. 05), and escape latency time of intervention group at 2-5 d were significantly shorter than those in model group (all P<0. 05). The number of times of crossing the platform in model group was significantly less than that in normal control group and intervention group ( all P<0. 05). Compared with those in model group, the expression of caspase-3 and p-tau in normal control group and intervention group were significantly lower (all P<0. 05). Conclusion β-C can reduce the impairment of learning and memory ability caused by OSAS, and the mechanism may be related to its inhibition of caspase-3 and p-tau protein expression.
