China Journal of Chinese Materia Medica 2019;44(10):2072-2077
Paclitaxel( PTX) is used as a broad spectrum anti-tumor medicine. However,serious drawbacks restrict clinical application of PTX. In this study,we prepared tumor-targeting and pH-sensitive lipoprotein-mimic nanocarrier containing paclitaxel( BSALC/DOPE-PTX) to study the effective antitumor activity. The in vivo targeting ability of the nanocarrier in tumor bearing nude mice was evaluated by using a Kodak in vivo imaging system FX PRO. The in vivo anti-tumor activity was evaluated in MDA-MB-231 tumor bearing mice,and representative sections were stained with hematoxylin and eosin( H&E),and examined by light microscopy. The results showed that DiR-loaded FA-BSA-LC/DOPE selectively targeted tumor,and had a relatively long residence in the tumor tissue. According to the in vivo anti-tumor activity study,FA-BSA-LC/DOPE-PTX exhibited an outstanding tumor inhibition effect with a tumor growth inhibition rate of 79.3%,and tumor tissue sections stained by hematoxylin and eosin( HE) showed severe necrosis areas and many dead cells with condensed nuclei in the FA-BSA-LC/DOPE-PTX group. Therefore,FA-BSA-LC/DOPE-PTX is a biocompatible,tumor-targeting and pH-sensitive lipoprotein-mimic nanocarrier,with a very marked anti-tumor activity in tumor-bearing mice in vivo.

OBJECTIVETo explore the value of the self-decompression bone block in interbody fusion.
METHODSFrom April 2014 to May 2015, 42 patients with degenerative lumbar instability and spinal stenosis were treated by posterior vertebral lamina decompression and pedicle nail-rod fixation and unilateral modified transforaminal lumbar interbody fusion, including 18 males and 24 females. The treatment group had 24 cases with autologous pure decompression bone block as single interbody fusion material and the control group had 18 cases with cage and autologous bone as interbody fusion material. Clinical data, bone healing time, interbody fusion rate, intervertebral height and curative effect were analyzed in two groups.
RESULTSAll the patients were followed up for 12 to 24 months with an average of 16 months. There was no significant difference in age, sex ratio, degree of lumbar instability, or follow-up time between two groups(>0.05); and there was no significant difference in curative effect, intervertebral height loss, or interbody fusion rate between two groups(>0.05).
CONCLUSIONSUsing self-decompression bone block fusion can get high fusion rate, maintain good intervertebral height, obtain satisfactory curative effect. Its design was scientific and reasonable with less complication, which provide an effective, economic, and practical method for degenerative lumbar instability and spinal stenosis.

Purpose:
Long non-coding RNA (lncRNA) is identified as an important regulator involved in oral squamous cell carcinoma (OSCC) tumorigenesis. This study aimed to investigate the functional role and underlying mechanism of LINC00662 in OSCC.
Materials and Methods:
The expression levels of LINC00662, miR-144-3p, and enhancer of zeste homolog 2 (EZH2) mRNA were quantified with quantitative real-time polymerase chain reaction in OSCC tissues and cell lines. Western blot analysis was used to assay the expression levels of E-cadherin, Vimentin, and EZH2. Cell proliferation, migration, and invasion were monitored by cell counting kit-8 and Transwell assays. Dual-luciferase reporter and RNA immunoprecipitation assays were employed to verify the regulatory relationship between LINC00662 and miR-144-3p.
Results:
The expression of LINC00662, positively associated with the increased TNM stage and lymph node metastasis of the patients, was up-regulated in OSCC tissues and cells. The overexpression of LINC00662 facilitated the proliferation, migration, and invasion of OSCC cells. MiR-144-3p could bind to LINC00662, and the promoting effect of LINC00662 overexpression was counteracted by miR-144-3p mimic. Moreover, EZH2 expression was negatively regulated by miR-144-3p and positively regulated by LINC00662. The silencing of EZH2 attenuated the promoting effects of overexpression of LINC00662 on cell proliferation, migration, invasion, and epithelial-mesenchymal transition.
Conclusion
LINC00662, as an oncogenic lncRNA of OSCC, accelerates OSCC progression by repressing miR-144-3p expression and increasing EZH2 expression.

To investigate the antidepressant mechanism of Shenling Kaixin Granules(SLKX) in treating chronic unpredictable mild stress(CUMS) model rats. Ninety male SD rats were randomly divided into control group, model group, Shugan Jieyu Capsules(110 mg·kg~(-1)) group and SLKX low-(90 mg·kg~(-1)), medium-(180 mg·kg~(-1)), and high-dose(360 mg·kg~(-1)) groups. Depression rat model was replicated by CUMS method. After treatment, the behavioral changes of rats were evaluated by sugar preference, open field, elevated cross maze and forced swimming experiments. The contents of interleukin 1 beta(IL-1β), tumor necrosis factor α(TNF-α), brain-derived neurotrophic factor(BDNF) and 5-hydroxytryptamine(5-HT) in serum were determined by enzyme linked immunosorbent assay(ELISA), and the activities of superoxide dismutase(SOD) and catalase(CAT) in hippocampal CA1 region were also detected. Pathological changes in hippocampal CA1 region were detected by hematoxylin-eosin(HE) staining, and Western blot was used to determine the expression of nerve growth factor(NGF), BDNF, phospho-tyrosine kinase receptor(p-TrkB)/TrkB, phospho-cAMP-response element binding protein(p-CREB)/CREB, nuclear factor E2 related factor 2(Nrf2), heme oxygenase 1(HO-1), B-cell lymphoma-2(Bcl-2)/Bcl-2 associated X protein(Bax) and caspase-3 in hippocampal CA1 region. RESULTS:: showed that compared with the control group, the model group had decreased sugar preference, reduced number of entries and time spent in the center of open field and shortened total distance of movement, reduced number of entries and proportion of time spent in open arm, and increased number and time of immobility in forced swimming experiment. Additionally, the serum contents of IL-1β and TNF-α and the expression of caspase-3 were higher, while the contents of BDNF and 5-HT, the activities of SOD and CAT in hippocampal CA1 region, the expressions of NGF, BDNF, p-TrkB/TrkB, p-CREB/CREB, HO-1 and Bcl-2/Bax, and the Nrf2 nuclear translocation were lower in model group than in control group. Compared with the conditions in model group, the sugar preference, the number of entries and time spent in the center of open, total distance of movement, and the number of entries and proportion of time spent in open arm in treatment groups were increased while the number and time of immobility in forced swimming experiment were decreased; the serum contents of IL-1β and TNF-α and the expression of caspase-3 were down regulated, while the contents of BDNF and 5-HT, the activities of SOD and CAT in hippocampal CA1 region, the expressions of NGF, BDNF, p-TrkB/TrkB, p-CREB/CREB, HO-1, Bcl-2/Bax, and Nrf2 nuclear translocation were enhanced. In conclusion, SLKX might regulate the Nrf2 nucleus translocation by activating BDNF/TrkB/CREB pathway, lower oxidative stress damage in hippocampus, inhibit caspase-3 activity, and reduce apoptosis of hippocampal nerve cells, thereby playing an antidepressant role.

This study aims to explore the neuroprotective mechanism of ginsenoside Re(GS-Re) on drosophila model of Parkinson's disease(PD) induced by rotenone(Rot). To be specific, Rot was used to induce PD in drosophilas. Then the drosophilas were grouped and respectively treated(GS-Re: 0.1, 0.4, 1.6 mmol·L~(-1); L-dopa: 80 μmol·L~(-1)). Life span and crawling ability of drosophilas were determined. The brain antioxidant activity [content of catalase(CAT), malondialdehyde(MDA), reactive oxygen species(ROS), superoxide dismutase(SOD)], dopamine(DA) content, and mitochondrial function [content of adenosine triphosphate(ATP), NADH:ubiquinone oxidoreductase subunit B8(NDUFB8) Ⅰ activity, succinate dehydrogenase complex, subunit B(SDHB) Ⅱ activity] were detected by enzyme-linked immunosorbent assay(ELISA). The number of DA neurons in the brains of drosophilas was measured with the immunofluorescence method. The levels of NDUFB8 Ⅰ, SDHB Ⅱ, cytochrome C(Cyt C), nuclear factor-E2-related factor 2(Nrf2), heme oxygenase-1(HO-1), B-cell lymphoma/leukemia 2(Bcl-2)/Bcl-2-assaciated X protein(Bax), and cleaved caspase-3/caspase-3 in the brain were detected by Western blot. The results showed that model group [475 μmol·L~(-1) Rot(IC_(50))] demonstrated significantly low survival rate, obvious dyskinesia, small number of neurons and low DA content in the brain, high ROS level and MDA content, low content of SOD and CAT, significantly low ATP content, NDUFB8 Ⅰ activity, and SDHB Ⅱ activity, significantly low expression of NDUFB8 Ⅰ, SDHB Ⅱ, and Bcl-2/Bax, large amount of Cyt C released from mitochondria to cytoplasm, low nuclear transfer of Nrf2, and significantly high expression of cleaved caspase-3/caspase-3 compared with the control group. GS-Re(0.1, 0.4, and 1.6 mmol·L~(-1)) significantly improved the survival rate of PD drosophilas, alleviated the dyskinesia, increased DA content, reduced the loss of DA neurons, ROS level, and MDA content in brain, improved content of SOD and CAT and antioxidant activity in brain, maintained mitochondrial homeostasis(significantly increased ATP content and activity of NDUFB8 Ⅰ and SDHB Ⅱ, significantly up-regulated expression of NDUFB8 Ⅰ, SDHB Ⅱ, and Bcl-2/Bax), significantly reduced the expression of Cyt C, increased the nuclear transfer of Nrf2, and down-regulated the expression of cleaved caspase-3/caspase-3. In conclusion, GS-Re can significantly relieve the Rot-induced cerebral neurotoxicity in drosophilas. The mechanism may be that GS-Re activates Keap1-Nrf2-ARE signaling pathway by maintaining mitochondrial homeostasis, improves antioxidant capacity of brain neurons, then inhibits mitochondria-mediated caspase-3 signaling pathway, and the apoptosis of neuronal cells, thereby exerting the neuroprotective effect.

OBJECTIVE:To investigate the effects of WeChat platform online service on the safety of pediatric family medica-tion and the quality of pharmaceutical care. METHODS:The online consultation records of"Qs and As for pediatric medications"were collected and summarized from the WeChat platform(WeChat ID:etyywd)during Jun.1st,2014-Dec.31st,2015 in our hos-pital. Statistical analysis was performed on the consulting time periods,age of pediatric patients with consultation demands,and the systems and mistake types involved in medication consultations. RESULTS:A total of 29 850 dialogue records on WeChat were collected,and 13 315 of these were related to medications(44.61%). The peak time of medication consultation was at 9:00-10:00 in the morning,with an accumulative consultation number of 1 840 cases(13.82%);while the least consultation time pe-riod was at 4:00-5:00 early in the morning,with only 13 cases(0.10%).Pediatric patients in need of consultation were more with-in the age of 1-6 years old,and most of them were preschool children(31.20%)and toddlers(26.32%). The systems consulted mainly involved the respiratory system,immune system and digestive system;in which respiratory system had the most cases (60.28%). There were 1 508 Qs and As records for medication mistakes that were occured or may occure and were corrected in time(11.33%),in which the mistake types were mainly the unsuitable use of antipyretics(3.91%),antibiotics abuse(3.14%), careless use of combination medication and excessive medication(3.04%),excessively large or small doses(0.69%),improper use of nebulized inhalant after discharge(0.41%),and excessive use of vitamins(0.14%). CONCLUSIONS:The WeChat plat-form expands the service scope of clinical pharmacists.As an extension of hospital pharmaceutical care,it reduces the risk of fami-ly medication mistakes due to a patient's or members'wrong recognition to a certain degree,reinforces communication between doctors and patients,and improves the experience of medical services.
