Objective:To observe the effect of acupoint massage plus acupoint sticking therapy for the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery.Methods:A total of 120 patients undergoing nasal endoscopic surgery were included,and all patients were under trachea intubation and general anesthesia.The patients were randomized into an observation group and a control group,with 60 patients in each group.Patients in the control group received conventional anesthesia resuscitation,while patients in the observation group received acupoint massage plus acupoint sticking therapy on the basis of conventional anesthesia resuscitation.Changes in the heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed at three time points including the end of the surgery (TO),the removal of the tracheal tube (T1) and 10 min after the removal of the tracheal tube (T2).The awakening and tube removal time,choking cough and restlessness,and adverse reactions (dizziness,nausea and vomiting) in 24 h post-surgery period were compared.Results:At T1 and T2,the comparisons of HR,SBP and DBP between the two groups showed statistical significance (all P＜0.05).Intra-group comparisons showed that the HR,SBP and DBP of the control group at T1 and T2 were significant different from those at TO (all P＜0.05).There were significant differences in the awakening time and tube removal time between the two groups (both P＜0.05).The incidences of choking cough and restlessness were 8.3％ and 3.3％ respectively in the observation group,versus 53.3％ and 30.0％ in the control group,and the between-group comparisons showed statistical significance (both P＜0.05).The incidences of dizziness,nausea and vomiting in 24 h post-surgery period were 3.3％,5.0％ and 0.0％ respectively in the observation group,versus 43.3％,33.3％ and 25.0％ in the control group,and the between-group comparisons showed statistical significance (all P＜0.05).Conclusion:Acupoint massage plus acupoint sticking therapy can effectively regulate the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery,and maintain a stable internal environment.

OBJECTIVETo screen the severe acute respiratory syndromes (SARS) mimotopes with random phage peptide library and to investigate their immunogenicity.

METHODSUsing SARS sera as selective molecule, a 12 mer phage peptide library was biopanned and positive clones containing the mimic epitopes were selected. The immuno-characteriation of the epitopes were then investigated.

RESULTS2 positive clones that having specific affinity to SARS sera were obtained. The DNA sequencing data showed no homology between the sequences of the deduced amino acid of the two mimic antigen peptides and the sequence of SARS.

CONCLUSIONSARS mimotopes were obtained by phage peptide library screening. This method might provide a new approach for SARS therapy and vaccine development.

Aim To explore the effects of Shp2 on cig-arette smoke extract (CSE)-induced epithelial-mesen-chymal transition (EMT). Methods The effects of CSE on TGF-β1 levels in epithelial cells were meas-ured by Q-PCR and ELISA. Immunofluorescent stai-ning was used to assess the expressions of CSE-induced EMT-related markers. The activation of CSE-induced Shp2,Smad2 was investigated by Western blot. Re-sults CSE induced Shp2 phosphorylation in a concen-tration-dependent manner in A549 cells. PHPS1 inhib-ited the increase in mRNA and protein expression of TGF-β1 induced by CSE. PHPS1 regulated the expres-sions of CSE-induced EMT markers (down-regulation of E-cadherin,up-regulation expression of Vimentin and α-SMA). The inhibition of either Shp2 inhibitor or Shp2 siRNA decreased Smad2 phosphorylation induced by CSE. Conclusions CSE initiates EMT through the Shp2 / Smad2 signaling pathway,which is activated by CSE through TGF-β1 generation. It is suggested that Shp2 might be a possible new target for COPD and lung cancer therapy.

Objective To investigate the effects of sitagliptin combined with premixed insulin on blood glucose fluctuations in patients with type 2 diabetes.Methods A total of 42 patients with type 2 diabetes from April 2012 to November 2013 were randomly divided into two groups, treated with insulin aspart 30 injections alone 2 to 3 times a day( control group, n=21 ) or combined with oral sitagliptin once a day ( treatment group, n=21).The glucose fluctuations by fingertip blood glucose and continuous glucose monitoring ( CGM) were assessed and the changes of glucose fluctuations in two groups before and after treatment were com-pared as well as the incidence of adverse reactions.Results Compared with before treatment, the data of blood glucose fluctuations index in two groups were significantly decreased after treatment.The fingertip blood glucose results showed that standard deviation of blood glucose( SDBG) , coefficient of varicotion( CV) and postprandial blood glucose index were lower in treatment group after treatment(P<0.05).The date from CGM showed SDBG [(1.77 ±0.53) vs ( 2.39 ±0.80 ) mmol · L-1 ], was significantly lower in treatment group than that in control group( P<0.05).MAGE and MODD in treatment group was decreased than control group [ MAGE ( 4.36 ±1.14 ) vs ( 5.82 ±2.44 ) mmol · L-1 and MODD ( 1.32 ±0.37 ) vs (1.71 ±0.65)mmol· L-1], but there was no statistical difference found(P >0.05).Hypoglycemia time ratio in treatment group was lower than that in control group [ ( 0.86 ±1.58 )% vs ( 2.95 ±2.39 )%, P <0.05 ].Conclusion Sitagliptin combined with premixed insulin is more safe and convenient for reducing blood glucose level and glucose fluctuations.

OBJECTIVETo explore the value of trisomy 22 ( +22) in the diagnosis of inv(16) acute myeloid leukemia (AML).

METHODSInterphase fluorescence in situ hybridization (FISH) was performed in 18 AML patients with +22. The probe was two-color break apart probe for CBFbeta with SpectrumRed on the centromeric side and SpectrumGreen on the telomeric side. The FISH results were compared with that of R-banding conventional cytogenetics (CC). Multiplex FISH (M-FISH) was used to analyze the relationship of +22 and inv(16).

RESULTSCC revealed inv(16) in none of the 18 AML, with +22, but FISH revealed inv (16) in 11 of them and del( 16) (q22) in one. As CC results, 9 of the 11 cases were sole +22, one complicated with trisomy 8, and one del(16) (q22). Four patients with +22 and inv(16) were analyzed by M-FISH and revealed +22 only.

CONCLUSION+22 can be regarded as an important marker for the diagnosis of inv(16) AML.

OBJECTIVETo report a case of acute myeloid leukemia (AML) with the insertion (8;21)(q22;q22.1q22.3). A 33-year-old Chinese woman was referred to our hospital. Hematologic data showed WBC 42.7 x 10(9)/L with monocytosis (monocyte counts 7.296 x 10(9)/L). Bone marrow aspirate was hypercellular with 4.5% monoblasts and 7.5% promonocytes. At first she was diagnosed with chronic myelomonocytic leukemia (CMML) according to the FAB criteria. Initially the patient received supportive care only, but her general condition rapidly became worse three months later. The monoblasts and promonocytes in the bone marrow rose to 20.5%. After two cycles of combined chemotherapy she obtained complete remission.

METHODSChromosome specimens were prepared by short-term culture of bone marrow cells. Karyotype analysis was carried out by R-banding technique. Three fluorescence in situ hybridization (FISH) analyses were performed using AML1-ETO dual color, dual fusion probe, whole chromosome painting 8 and 21 probes, and cen-8 and Tel 21qter probes, respectively. Reverse transcription polymerase chain reaction (RT-PCR) assay for detecting the AML1-ETO fusion transcript was also performed.

RESULTSConventional cytogenetic analysis showed a karyotype of 46,XX,ins(8;21) (q22;q22.1q22.3)[7]/46,XX[3]. FISH tests confirmed the insertion. RT-PCR analysis detected the AML1-ETO fusion transcript.

CONCLUSIONWe consider that this patient should be rediagnosed as acute myeloid leukemia according to the criteria proposed by World Health Organization (WHO) and that FISH and RT-PCR play an important role in verification of the ins(8;21).

OBJECTIVETo explore the effects of survivin antisense RNA on taxol-induced apoptosis in leukemia cell line HL-60.

METHODSA survivin antisense eukaryotic vector pcDNA3-SVVas was transferred into HL-60 cells by electroporation. The live fraction was determined by trypan blue dye exclusion assay. Cell counting and MTT assay were performed to evaluate the sensibility of the transfected cells to taxol. Apoptosis was detected by DNA gel electrophoresis and nuclear staining.

RESULTSTwo positive cell clones, HL-60 SVVas and HL-60 neo were obtained. Compared to HL-60 and HL-60 neo cells, HL-60 SVVas cells growth was significantly reduced (P < 0.05). By MTT assay, the IC(50) of taxol to HL-60 SVVas, HL-60 neo and HL-60 cells were (14.4 +/- 1.87) ng/ml, (31.9 +/- 6.38) ng/ml and (32.0 +/- 3.52) ng/ml, respectively, the difference was significant by statistic analysis (P < 0.01). Agarose gel electrophoresis of genomic DNA from HL-60 SVVas showed typical DNA ladder, but DNA from HL-60 neo and HL-60 did not. Nuclei become condense in HL-60 SVVas cells.

CONCLUSIONSurvivin antisense RNA could enhance taxol-induced apoptosis in leukemia cell line HL-60. This may lay an experimental foundation for further research of gene therapy in leukemia.
