ABSTRACT
Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation, namely the Warburg effect. Even under aerobic conditions, tumor cells mainly rely on glycolysis to provide energy. Therefore, glucose transporter protein 1(GLUT1), which is involved in the process of glucose metabolism, plays an important role in tumorigenesis, development and drug resistance, and is considered to be one of the important targets in the treatment of malignant tumors. In recent years, research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism, among which the role of GLUT1 is the most critical. In this paper, the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine(TCM) active ingredient nano-delivery system in tumor therapy, aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention(EPR) effect. In summary, the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.
ABSTRACT
OBJECTIVE:To analyze the safety of linezolid (LZD) for elderly patients,and probe into the regularity of adverse reaction (ADR).METHODS:In retrospective study,elderly patients treated with LZD injection or tablets were selected from our hospital during Jan.2014-Dec.2015.The occurrence of ADRs were analyzed statistically.RESULTS:A total of 126 patients were included,the age was from 65 to 94 year-old,and the mean duration of treatment was (9.47 ± 6.31) d (ranged 1-35 d).Forty-five cases suffered from ADR after medication (35.71%),followed by 39 cases of thrombocytopenia (30.95%),9 cases of leukocytopenia(7.14 %),7 cases of hemoglobin reduction (5.55 %),6 cases of nausea and vomiting (4.76 %),4 cases of transaminase elevation (3.17%),4 cases of diarrhea (3.17%),2 cases of lactic acidosis (1.59%),2 cases of skin rash (1.59%) and 1 case of drug fever (0.79%).The incidence of thrombocytopenia in ICU patients was significantly higher than non-ICU patients,with statistical significance (P=0.019).There was no significant difference among different dosage forms of LZD without statistical significance (P=0.218).CONCLUSIONS:Clinicians and pharmacists should closely monitor the application of LZD in elderly patients,pay more attention to ADR induced by LZD,especially in ICU,it induces the high incidence of thrombocytopenia.Meanwhile,it is suggested to monitor serum lactate concentrations regularly during treatment.
ABSTRACT
Objective To retrospectively analyze the effect and safety of bilateral stereotactic radiofrequency amygdalohippocampectomy (SAHE) for treatment of bilateral medial temporal lobe epilepsy (BMTLE). Methods Twelve BMTLE patients were treated with bilateral SAHE under limited coagulations. Clinical parameters were evaluated with the programs of Engel′s classification, Liverpool Seizure Severity Scale (LSSS) 2.0, Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wechsler Memory Scale-Revised (WMS-R), respectively. Results Five patients (42%) were assessed as EngelⅠwith 12 ~ 62-month follow-up. Seizure severity scores were declined sharply compared with the baseline of the patients with out seizure free. Function of memory and intelligence was transiently declined without statistical significance immediately after operation (P >0.05), but was significantly increasedat 6 months after operation (P < 0.05). Conclusion Bilateral SAHE could terminate seizures or reduce seizure severity in patients with BMTLE. Under the circumstance of limited coagulations, neuropsychological function was improved along with seizure control.
ABSTRACT
70 patients including 60 cases under acupuncture anesthesia and 10 cases under drug anesthesia were observed. Before and 20 minutes after acupuncture the blood samples were taken from the patient ear lobes respectively, and in some patients taken once again 24 hrs after acupuncture. The electroacupuncture point Hegu or Zusanli was mainly adopted. As the method for detection of cell-mediated immunity(CMI) in vitro the improved microtechnique of whole blood for E-rosette (active and nonactive) and lymphocyte transformation tests was used. In performance of active rosetting the total leucocyte count and the differential lymphocyte count were done for calculation of absolute number of active rosette forming cells (RFC). The mean value of increase of active RFC was 12.7?1.43, the decrease was 6.8?1.77 after acupuncture. The increment of the absolute number of active RFC was 175?63.59. However no marked effect on the drug anesthesia group was found. In the lymphocyte transformation assay the increase was 12.7?1.49, the decrease was 7.0?2.19, and the enhancement effect still exhibited 24 hrs after acupuncture. In these tests an increase was mostly found in those with a lower or a usual CMI level; a decrease often found in those with a higher CMI level prior to acupuncture. The increase or decrease level in the results of three kinds of test (active, nonactive RFC and lymphocyte transformation) was similar, the increase range was 12~13%, the decrease range 6~7%. As the former compared with the latter, the promotion was prominent by all means.
ABSTRACT
The cholinesterase(ChE)and lactate dehydrogenase(LDH)activities in blood smears of 37 patients were observed before and 20 minutes after electroacupuncture.Hegu and Zusanli were mainly chosen as the acupuncture points.Karnovsky method was used to demonstrate ChE,activity,and tetrazolium-formazan reaction for LDH activity. Before acupuncture,all formed elements of blood showed both ChE and LDH acti- vities.In red blood cells ChE and LDH activities were localized at the cell membrane, while in white blood cells they were found throughout the cytoplasm as colored granu- les.The granulocytes showed greater ChE and lesser LDH activities than the lymph- ocytes.The platelets also showed greater LDH and ChE activities,especially the former. On the whole,platelets and leucocytes,as compared with erythrocytes,showed greater activities for ChE and LDH. Under microscopic observation,according to the amount and color of granules,the degrees of GhE and LDH activities for each kind of blood formed elements before and after acupuncture were recorded as different markes,such as +、++、+++ and so on.The degrees of GhE or LDH activity in various formed elements of blood were compared by means of statistical tests.After acupuncture,both GhE and LDH activities of all blood formed elements were increased(p
