Objective To observe the effect of antisense hypoxia inducible factor-1?(HIF-1?) on (chemosensitivity) of human pancreatic cancer cell line BxPC-3 under hypoxia. Methods BxPC-3 cells were divided into 3 groups:(1)BxPC-3 cells were non-transfected with antisense HIF-1? plasmid and exposed to 0.5% O_2 for 4hr(hypoxia control);(2)normoxic BxPC-3 cells were non-transfected with antisense(HIF-1?) plasmid(normoxia control);(3)BxPC-3 cells were transfected with antisense HIF-1? plasmid and exposed to 0.5% O_2 for 4hr(experimental group).Expression of HIF-1? and survivin was detected by RT-PCR and Western Blot.Growth inhibition rates and apoptosis rates of BxPC-3 cells under different(dosages) of chemotherapeutic agents(5-fluorouracil,doxorubicin and gemcitabine) were measured by MTT(colorimetric) assay and flow cytometry (FCM).Results Expression of HIF-1? was obviously down-regulated and at the same time susvivin expression was markedly down-regulated in experimental group(P

Objective To study the detection rate of contrast-enhanced ultrasound (CEUS) with different perfusion methods on rabbit VX2 small hepatocellular carcinoma less than 10.0 mm. Methods VX2 tumor cells were inoculated into the subcutaneous tissue of New Zealand rabbit′s thigh. Then the plant tumor were cut into small blocks under sterile conditions and transplanted into hepatic parenchyma in 30 New Zealand rabbits. The contrast media was injected through peripheral vein by single and double perfusion methods. The detection rate of two methods were compared. Results There were 41 hepatocellular carcinoma lesions in the 30 rabbits. There were 15 lesions with size between 3.0 mm and 5.0 mm, and 26 lesions between 5.0 mm and 10.0 mm in diameter. On CEUS, the VX2 tumor presented fast-in and fast-out pattern. In arterial phase, the lesion was enhanced rapidly. In portal venous phase, contrast began to wash out from the carcinoma. In delay phase, the enhancement of lesion was signiifcantly lower than the surrounding normal liver parenchyma. A total of 32 lesions were detected by single perfusion method, including 7 lesions ranging 3.0-5.0 mm and 25 lesions ranging 5.0-10.0 mm. A total of 39 lesions were detected by double perfusion method, including 13 lesions ranging 3.0-5.0 mm and 26 lesions ranging 5.0-10.0 mm. The detection rate of micro-hepatocellular carcinoma by single and double perfusion method was 78% and 95% respectively. The difference was statistically signiifcant (χ2=5.150, P=0.023). The detection rate of 3.0-5.0 mm lesions by single and double perfusion method was 47%and 87%, respectively. The difference was statistically signiifcant ( χ2=5.400, P=0.025). The detection rate of 5.0-10.0 mm lesions by single and double perfusion method was 96% and 100%, respectively. There was no statistically signiifcant difference (χ2=1.020, P=0.500). Conclusion The double perfusion method greatly promotes the detection of micro hepatocellular carcinoma, especially for the lesions less than 5.0 mm in diameter.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

OBJECTIVETo explore the conversion rule of serological blood group and blood group substance after successful allogeneic hematopoietic stem cell transplantation, and to provide theory for clinical special blood type identification and blood transfusion.

METHODSThe growth cycle of recipient WBC and RBC, RBC chimera, blood group antibody production and remaining in full transition were observed. Conversion rule of blood group substance, contradiction between cells typing and sera typing were detected by saline medium tube method and microcolumn gel method after stem cells transplantation.

RESULTSThe average time of engraftment in 21 recipients was about 18.6 days, RBC growth cycle in 8 major blood type incompatibility was 56.6 days, 25.9 days in 9 minor blood type incompatibility, 67 days in 4 bidirectional blood type incompatibility (P < 0.01). The ratio of RBC chimeric growth was 1:9, gradually converse to donor's blood group. Residue of recipient anti-A(B) was left after conditioning regimen, disappeared after full transformation, and recipient anti-A(B) was converse to donor's blood type in major blood type incompatibility. 5 A blood type recipient donated by O blood type blood generated anti-B instead of anti-A, 3 B blood type recipient generated only anti-A instead of B in minor blood type incompatibility, and 1 AB blood type recipient donated by A did not generate anti-B. Among 4 bidirectional blood type incompatibility, 2 B blood type recipient donated by A blood type blood did not generate anti-B, 2 A recipient by B could not produce anti-A. Recipient blood group substance helped original ABO blood type substance remain unchanged.

CONCLUSIONAmong patient with allogeneic hematopoietic stem cell transplantation, recipient's ABO and RBC blood type can be converse to donor's, but there is significant difference between patients of serological blood group and of normal people (P < 0.01). Recipient blood group substance helps original ABO blood type substance remain unchanged (P > 0.01).

Objective To examine the correlation between end-tidal carbon dioxide (PetCO2) and arterial CO2 (PaCO2) among patients admitted in neurosurgical intensive care unit (NICU) and the factors affecting the PaCO2-PetCO2 [P (a-et) CO2].Methods Thirty-two intubated or cut-trachea patients who presented in the NICU were enrolled.Arterial blood gas test was done at seven every morning,and values of PetCO2 were compared with simultaneously recorded PaCO2.The normal gap of P (a-et) CO2 was defined as-5 mmHg to 5 mmHg.Concordance between PaCO2 and PetCO2 was analyzed using the Bland-Altman plot.Parameters between the normal and high P(a-et) CO2 groups were compared to identify the factors affecting the P(a-et) CO2,including Glasgow Coma Scale(GCS),blood pressure (BP),heart rate (HR),respiration rate (RR),body temperature (BT),and pulse oxygen saturation (SpO2).Results Allvalues of PaCO2 and PetCO2 were in accordance with normal distribution (r =0.668,P ＜ 0.01) and concordance between PaCO2 and PetCO2 was 69.8％.Patients who had high P(aet) CO2 showed lower initial GCS,lower instant GCS,BT,as well as pH and higher actual bicarbonate (AB) and PetCO2 than the patients with normal P (a-et) CO2.Correlation between PaCO2 and PetCO2 rapidly declined when positive end expiratory pressure(PEEP) was greater than 5 mmH2O(r =0.229,P ＜ 0.01).Conclusions PetCO2 correlates well with PaCO2 and appears to be a useful monitor of respiratory function of the patients consecutively.Initial GCS,BT,AB and PEEP have an impact on P(a-et) CO2,so those factors should be considered when attempting to monitor the hyperventilation with PetCO2.

Objective To investigate the effect of integrin-?1 antisense oligodeoxynucleotide(ASODN) on(human) pancreatic cancinoma transplanted subcutaneously in nude mice.Methods The models of human(pancreatic) cancinoma transplanted subcutaneously were established in nude mice,then divided randomly into 3 groups and different treatment was given respectively(control group,random oligodeoxynucleotide group and ASODN group).After treatment,the weight of nude mice and tumor volume were observed,and the tumor growth inhibitory rate and the tumor response rate were calculated.The expressions of integrin-?1 mRNA and protein in tumor tissue were determined by RT-PCR and Western-blot.Results The tumor growth inhibitory rate in the random oligodexynucleotide group and the ASODN group was 4.75% and 72.70%,respectively.The tumor decrease rate of the ASODN group was 10.91%.The expression level of integrin-?1 mRNA and protein was decreased in the ASODN group compared with other 2 control groups. Conclusions Our findings suggest that integrin-?1 antisense oligodeoxynucleotides result in marked inhibition of human pancreatic(cancinoma) growth in nude mice.It may be a novel treatment approach for human pancreatic carcinoma.

Objective To investigate the changes in cortisol (COR) secretion in the acute phase of traumatic brain injury (TBI) .Method Seventy-five patients admitted to the hospital at 2-24 h after TBI were divided into 3 groups based on the Glasgow Coma Scale score: mild TBI group (group TBI1, n = 30), moderate TBI group (group TBI2, n = 12) and severe TBI group (TBI3, n = 33). Thirteen patients with cervical spondylosis or osteoma of the skull (admitted to the hospital at the same period) were regarded as control group (group C). Venous blood samples were taken on the first day after admission to measure the serum concentrations of total COR, adrenocorticotropin (ACTH) and corticosteroid-binding globulin (CBG). Free COR concentrations and free COR index were calculated. High blood COR was recorded. Result Compared with group C, the serum concentrations of total COR and ACTH, free COR levels and free COR index were significantly increased in TBI1, TBI2 and TBI3groups (P ＜ 0.05). The parameters mentioned above were significantly higher in TBI2 and TBI3 groups than in TBI1 group ( P ＜0.05). There was no significant difference in serum CBG concentrations among the four groups.The incidence of high blood COR was significantly higher in TBI1, TBI2 and TBI3 groups than in C group, and in TBI3 group thanin TBI1 and TBI2 groups (P ＜0.05). Conclusion COR secretion is increased in the acute phase of TBI and the level of COR secretion is related to the severity of brain damage.

In order to study the the impact of cognitive difference between doctors and patients on doctor-patient relationship, five tertiary hospitals in city B were investigated with questionnaire and quantitative interviews, and the outcomes were analyzed with SPSS16. 0 software. Cognitive differences were found in the nature of the relationship, the main part of responsibility for the relationship, and principles for communication between the parties. By analyzing the causes of the difference and their impact on the relationship, it draw the conclusion that this cognitive difference found between the two parties functions as a key to the conflicts between doctors and patients. Return of health care back to non-profit nature, encouragement of patient-doctor communication and mutual understanding will be conducive to minimizing such a cognitive difference, and building a harmonious doctor-patient relationship.

Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.
