ABSTRACT
Hyperventilation syndrome(HVS)in children is a common functional respiratory disorder with a group of symptoms mainly characterized by hyperventilation, which is usually triggered by anxiety or stress events.A standardized questionnaire and the hyperventilation provocation test are helpful for diagnosis.Currently, the Nijmegen questionnaire is a common clinical tool to quantify and assess the severity of the symptoms.Emotional and psychological factors are major causes of HVS onset, meanwhile, abnormal breathing patterns are also implicated.Reassurance therapy and breathing retraining can improve the symptoms.
ABSTRACT
Objective To study the temozolomide combined with curcumin on the inhibitory effect and apoptosis of the C6 glioma cells. Methods The C6 glioma cells were treated with temozomide in combination with curcumin. The anti proliferation effect of liposomes on the C6 glioma cells was investigated by using the method of sulforhodamine B (SRB). Flow cytometry was used to detect apoptosis of the C6 glioma cells. Confocal laser scan-ning microscope was used to observe apoptosis and location in the C6 glioma cells. Results The results of SRB as-say showed that temozolomide in combination with curcumin inhibition rate were (91.22 ± 0.51)%in 48 h of the C6 glioma cells; Flow cytometry showed that the apoptosis rate were (33.15 ± 0.79)% with temozolomide (5 μmol/L) in combination with curcumin (10 μmol/L). Laser scanning confocal scanning microscope indicated that the apop-tosis of in the C6 glioma cells treated with temozolomide in combination with curcumin was more than that of free drug. Conclusion The temozolomide in combination of curcumin can inhibit the growth and induce apoptosis of the C6 glioma cells.
ABSTRACT
Aim To establish ICR animal model with C6 glioma stem cells, to provide the ideal model for the further study of gli-oma stem cells in brain glioma model. Methods C6 glioma stem cell was cultured in vitro by suspension,and was identified with Nestin antibody. C6 stem cells of ICR mouse glioma model were used to investigate survival state and tumor volume in mice after the operation. HE staining and CD133 immunohistochemi-cal study were adopted to investigate the postoperative pathologi-cal changes in mice. Results The expression of Nestin was 96. 01% in C6 glioma stem cells, and Nestin was highly ex-pressed in the cultured C6 glioma stem cells. Mice were inocula-ted with tumor after loss of appetite, weight, behavior and slow, sluggish reaction. Tumor volume at day 21 after modeling was (9. 77 ± 6. 58) mm3 . After HE staining, the model showed the invasive growth, tumor cell shrinkage and derangement. Immu-nohistochemical CD133 staining revealed that tumor cytoplasm color was brown. Conclusion Glioma model can be established based on glioma stem cells into a high rate of tumor, the tumor cycle is short, which can be used as an ideal model for glioma.
ABSTRACT
Acute traumatic coagulopathy (ATC) attacks suddenly with a rapid progress and has an extremely highly mortality.Of late years more and more relative studies have made a great progress on the pathogenesis,diagnosis and treatment of ATC.However,there are currently no medical guidelines for ATC.There are still some problems such as nonstandard treatment,outdated concept and so on in clinic.Based on the latest research progresses home and abroad,this paper expounds emphatically the first-aid and treatment of ATC in order to bring helps to the clinical doctors.
ABSTRACT
In this study, we developed a novel liposome-silica hybrid nano-carrier for tumor combination therapy via oral route, using paclitaxel and cyclosporine as a model drug pair. Optimization of the preparation of the drug-loading formulation and characterization of its physicochemical parameters and drug release profile were performed in vitro. Then in vivo pharmacodynamics and pharmacokinetics studies were performed. The results showed that the obtained formulation has a small particle size (mean diameter of 100.2 +/- 15.2 nm), a homogeneous distribution [the polydispersity index was (0.251 +/- 0.018)] and high encapsulation efficiency (90.15 +/- 2.47) % and (80.64 +/- 3.52) % for paclitaxel and cyclosporine respectively with a mild and easy preparation process. A sequential drug release trend of cyclosporine prior to palictaxel was observed. The liposome-silica hybrid nano-carrier showed good biocompatibility in vivo and co-delivery of cyclosporine and paclitaxel significantly enhanced the oral absorption of paclitaxel with improved anti-tumor efficacy, suggesting a promising approach for multi-drug therapy against tumor and other serious diseases via oral route.

METHODS: Zero Inventory of Chinese decoction pieces was analyzed from aspects of hospital resource utilization, pharmacy management, and quality assurance of decoction pieces. RESULTS: Zero Inventory can help save precious hospital resources, streamline pharmacy management and ensure quality of decoction pieces supply. CONCLUSION: Zero Inventory of Chinese decoction pieces has positive impact on hospital pharmacy management; therefore it deserves to be popularized.
ABSTRACT
Objective: To investigate jugular bulb venous oxyg en partial pressure(PjO2)， hemoglobin saturation (SjO2) and the arterial t o jugular bulb venous oxygen content difference(AjDO2) during anesthesia with desflurane and isoflurane in patients with brain tumor. Methods: Fifty-six patients with brain tumor were randomized into desflur ane or isoflurane for maintaining anesthesia. PjO2, SjO2 and AjDO2 in pati ents were measured during normoventilation, hyperventilation and hypoventilation . Results: During normoventilation， SjO2 and PjO2 in desflu rane group was significantly higer than those in isoflurane group（P<0.05 or P<0.01）, and AjDO2 in desflurane group was significantly lower than that in isoflurane group（P<0.05）.Except that PjO2 in desflurane group was si gnificantly higer than that in isoflurane group during hyperventilation （P< 0.01）, there were no differences in SjO2, PjO2 or AjDO2 between the 2 g roups during hyperventilation or hypoventilation. While anesthesia with desflura ne and isoflurane, there was a positive correlation between PaCO2 and SjO2. Conclusion: At the same anesthetic effect concentration, desflur ane can significantly increase SjO2 and PjO2 in comparison to isoflurane un der normoventilation, suggesting that desflurane may have stronger effect of rel axing cerebral vessel than isoflurane.
ABSTRACT
Objective:To evaluate the protective effect of ?-opioid peptide,[D-Ala~(2)-D-Leu~(5)]-enkephaline(DADLE), on pulmonary ischemia-reperfusion(I-R) injury after cardiopulmonary bypass(CPB),and to discuss the possible mechanism.Methods: Twenty-eight male pigs were evenly randomized divided into 4 groups,namely,the sham-operation group,the CPB group(only subjected to CPB),the DADLE pretreatment group(received DADLE 1 mg?kg~(-1)before CPB),and the Glibenclamide group(received DADLE 1 mg?kg~(-1)and glibenclamide 1 mg?kg~(-1) before CPB).Peak inspiratory pressure(PIP),PaO_(2),and the plasma malondialdehyde(MDA) concentration were measured in each group before CPB and 10 min,30 min,and 60 min after reperfusion.The changes of lung tissue wet weight/dry weight ratio(W/D) were calculated before CPB and 60 min after reperfusion.The animals were sacrificed 60 min after reperfusion to observe the ultrastructural changes of the lungs and to quantitatively assess lung tissue damage(LTD).Results: There were no significant differences among the 4 groups before CPB and the parameters in(sham-operation) group had no changes at all specified time points.One hour after reperfusion,the PIP,MDA,W/D,and LTD values in Glibenclamide and CPB groups were significantly higher than those in sham-operation and DADLE groups while the PaO_(2) was significantly lower(P
