HA1 1 7,as a multiple drug resistance(MDR)gene,has recently been discovered.It may mediate the MDR of tumor through Bcl-2 anti-apoptotic pathways.HA1 1 7 gene exists high expression in leuke-mia,lymphoma,breast cancer,neuroblastoma,colon adenocarcinoma and so on,and its overexpression is closely associated with the MDR and poor prognosis of these tumors.

Objective:To study the characteristic of energy metabolism in moderate and severe OSA before and after CPAP. Methods:The REE was measured before and after 5-8 week treatment by CPAP in OSA patients. Health staff of single obesity in the hospital were as control. Results:During sleep, the enengy-metabolism was increased significantly in OSA patients. After treatment by CPAP, it was decreased (P

Objective To investigate the relationship of intraoperative cerebral oxygen saturation(rSO_2 )monitored with near-infrared cerebral oximeter (INNOS 5100) and postoperative cognitive dysfunction in patientsoperated upon under isoflurane or sevoflurane anesthesia and to determine the critical rSO_2 value below whichpostoperative cognitive dysfunction may occur.Methods Sixty ASA Ⅰ- Ⅱ patients of both sexes aged 62-80 yr,weighing58-77 kg schedules for elective abdominal surgery or surgery on the low limb were divided into threegroups according to their levels of education: group Ⅰthe illierate and uneducated (n = 20); group Ⅱ primaryschool education (6yr education (n = 20). Each group was furtherdivided into isoflurane and sevoflurane subgroups (n = 10 in each subgroup). The patients were unpremedicated.Anesthesia was induced with intravenous atropine 0. 3mg, propofol 1 .0-1. 5 mg?kg~(-1), fentanyl 2-3?g?kg~(-1) andvecuronium o. 1-0.2 mg?kg~(-1) and maintained with isoflurane or sevoflurane inhalation (0.9-1. 1 MAC )supplemented with intermittent i.v. boluses of fentanyl and recorded before anesthesia (baseline), after O_2inhalation(T_1), after induction of anesthesia(T_2), after skin incision (T_3), during operation (T_4)and at the end ofsurgery (T_5). Mini-Mental State Examination (MMSE) was performed before anesthesia and 1,4, 8, 12 and 24 hafter surgery. BP, HR, ECG, SpO_2, P_(ET) CO_2 and end-tidal concentration of inhalational anesthetics werecontinuously monitored during anesthesia. Results In all three groups rSO_2 was significantly lower during operation(T_4) and at the end of surgery (T_5 ) than baseline (T_0 ) (P

The dissolution rates of the cephalexin tablets made by five t actories in China were determined with rotating basket method. The dissolution constants Ki were calculated using single exponential method. The analysis of variance was carried out for Ki. The results showed that constants Ki of products from different factories were significantly different (p

Objective To evaluate the effiicacy of nasotracheal intubation using blind tracheal intubation device and end-tidal carbon dioxide monitoring technique in patients with difficult airway.Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes,aged 35-60 yr,weighing 55-75 kg,requiring nasotracheal intubation,undergoing selective oral and maxillofacial surgery,were involoved in this study.All of them were expected to have difficuh airway such as mouth opening ＜ 3 cm,neck upward degree ＜ 30° and Mallampati classification Ⅲ or Ⅳ,The patients were randomly divided into 2 groups(n =30):group Ⅰ received tracheal intubation with the blind tracheal intubation device and group H received tracheal intubation with the blind intubation device combined with end-tidal carbon dioxide monitoring technique.The number of successful intubation,the inlubation time and adverse effects during intubation(epistaxis,tachycardia,hypertension and hypoxemia)and after operation(sore throat and hoarseness)were recorded.Results The rate of successful intubation in the two groups was 100％.Tachycardia,hypertension,hypoxemia and hoarseness were not found in the two groups.Compared with group I,the rate of successful intubation at first attempt was significantly increased,the intubation time was significantly shortened,and the incidence of epistaxis and sore throat was decreased in group Ⅱ(P ＜ 0.05).Conclusion The blind intubation device combined with end-tidal carbon dioxide monitoring technique used in diffficult airway can shorten the intubation time,increase the success rate of tracheal intubation,and decrease the occurrence of adverse effects.

Eighty-seven patients with hyperthyroidism were enrolled in a retrospective study,and 35.6％ of them also suffered from pulmonary hypertension(PH).Advanced age and systolic or diastolic dysfunction of left heart were risk factors in the mechanism of PH associated with hyperthyroidism (all P＜0.05).However,autoimmune disorder was found as a non-related factor in the mechanism of PH(P＞0.05).

Objectives:To observe the effect of rhGH in the treatment of chronic wasting diseases. Methods:Twenty two cases of chronic wasting diseases needing nutrition support were chosen,including 10 cases of COPD,12 cases of cerebral infarction or cerebral hemorrhage with decubital ulcer in recovery phase.They were in the age of 60～75,in combination with morderate malnutrition.These patients were divided into control group and experimental group.In the experimental group,rhGH(4.5 U/d) was given hypodermically for 10 days.Serum albumin,prealbumin,transferin,24 h urea nitrogen in urine,the surface area of decubital ulcer and mental state were monitored before and after the treatment. Results:In the experimental group,many nutritional indices were increased markedly,24 h urea nitrogen excretion was decreased,the healing of decubitus was faster and mental state was better when compared with control group. Conclusions:The rhGH plays an important role in improving the nutritional status and mental state in patients with chronic wasting diseases. On the base of supplying enough nutrients, rhGH can promote anabolism,reduce the excretion of urea nitrogen in urine, accelerate the healing of decubital ulcer and improve the prognosis.

Objective: To investigate a new strategy to reverse multidrug resistance of chronic myeloid leukemia cell line K562 by RNA interference technique through constructing an eukaryotic vector of short hairpin RNA (shRNA) targeting homeobox A10 (HOXA10) gene. Methods: The eukaryotic vector pGPHI/GFP/Neo-HOXA10 with shRNA targeting HOXA10 gene was constructed and then transfected into K562 cells by positive ion liposome. The stable transfectants were vertificated by reverse transcriptase PCR (RT-PCR) 4 weeks after G418 pressure selection. The changes of sensitivity of K562 cells to leurocristine (VCR) and etoposide (VP-16) after transfection with shRNA-HOXA10 were detected by MTT method, and the apoptosis rate was detected by flow cytometry. Results: After selection with G418, the cell clones stably transfected with pGPHI/GFP/Neo-HOXA10 were successfully constructed and verificated by RTPCR. The half inhibitory concentration (IC50) values of VCR and VP-16 for K562 cells transfected with shRNA-HOXA10 were significantly reduced and the apoptosis rate of K562 cells after HOXA10 gene interference combining with chemotherapy was increased significantly as compared with those of shRNA-negative control group and the normal control group (P<0.05). No differences in IC50 and apoptosis rate were observed between the shRNA-negative control group and the normal control group (P>0.05). Conclusion: The eukaryotic vector of short hairpin RNA (shRNA) targeting HOXA10 gene can enhance the abilities of VCR and VP-16 to inhibit the cell proliferation and induce the apoptosis of K562 cells, namely an increase of sensitivity to these chemotherapeutics in K562 cells. It is hinted that RNA interference targeting HOXA10 gene may reverse the multidrug resistance of leukemia cells in some degree. Copyright© 2011 by TUMOR.
