Objective:To compare psychosocial factors and immune function between patients with breast cancer and benign tumor before operation.Methods:The patients of breast tumor(56 case)were measured by clinical psychological rating scale(EPQ、HAMD、HAMA、LES、SSRS、DSQ)before operation,and their serum levels of IgA, CD_4~+,CD_(19)~+ and the activity of NK cell were measured.The patients of breast tumor were divided into breast cancer group(36 case)and benign tumor group(22 case)bases on results of pathology.Results:In breast cancer group, there were significantly higher scores of neurotic,total and negative life events,immature defense styles,HAMA and HAMD than those in benign tumor group;while NK cell activity,levels of CD_4~+ and CD_(19)~+ and the score of mature defense,social supports,subjective supports and utility degree of supports were marked lower.There were significantly correlation between immune function(NK cell activity,content of CD_4~+,CD_(19)~+,IgA)and psychosocial factors(social support,P score of EPQ,HAMD and HAMA total score,quantity of negative life events etc). Conclusion:Cancer patients had more server psychosocial problems and lower immune function.The immune function of patient with breast cancer before operation is associated with the various psychosocial factors.

Specific primers 1CaA/1CaB for full cry1C gene in Bacillus thuringiensis subsp.colmeri strain 15A3 were designed. The 4.0kb PCR product included the whole ORF and regulation region of cry1C gene. This PCR product was linked with shuttle vector pHT315 by two cloning steps. The recombined plasmid pHT-1C was electroporated into Bacillus cereus 9509, a kind of bacteria that beneficial to crops. The transformant could produce bipyramidal-shaped parasporal inclusions. The 60kD protein band was detected by SDS-PAGE. The bioassay result showed that the cry1C gene transformant of Bc 9509 had insecticidal activity to Spodoptera exigua.

OBJECTIVETo evaluate the monitoring of ultrasonography in artificial vascular graft for arteriovenous fistula and its complications in patients with chronic renal failure.

METHODSEighteen cases of artificial vascular graft arteriovenous fistula after four to six weeks were enrolled. The diameter, the peak velocity and blood flow were examined in arterial fistula. And the artificial vascular diameter, the peak velocity and blood flow of artificial vessels next to artery were all examined and analyzed. And the patients with symptoms in the upper extremity were tested by ultrasound.

RESULTSIntravascular blood showed good filling in fistula and artificial blood vessels in four to six weeks after artificial vascular graft for arteriovenous fistula by color doppler ultrasonography. The arterial fistula diameter, the peak velocity and blood flow were (3.61 +/- 0.68) mm and (298.56 +/- 93.42) cm/s and (583.62 +/- 216.77) ml/min. Artificial vascular diameter in (4.47 +/- 0.61) mm, the peak velocity and blood flow were (219.37 +/- 68.42) cm/s and (325.23 +/- 117.12) ml/min in the artificial blood vessels next to artery. Seven patients with upper extremity discomfort were examined by ultrasonography. One case was serum swollen. Three cases were thrombosis in artificial vessels. One case was pseudoaneurysm. Two cases were edema.

CONCLUSIONSUltrasonography plays a significant clinic role in testing artificial vascular graft for arteriovenous fistula and its complications.

OBJECTIVETo explore the values of tissue factor (TF) and vascular endothelial growth factor (VEGF) expressions on peripheral CD14+ monocytes in disease assessment, prognosis, and short-term efficacy evaluation of non-Hodgkin lymphoma (NHL) patients.

METHODSTF and VEGF expressions on CD14+monocytes in 47 NHL patients (disease group) before chemotherapy and after 4 chemotherapy cycles and in 30 healthy subjects (control group) were detected by flow cytometry, and the potential relationship among TF, VEGF, International Prognostic Index (IPI), and short-term efficacy were analyzed.

RESULTSTF and VEGF expressions on CD14 + monocytes in disease group were significantly higher than those in control group ( all P <0. 01) and positive correlation was showed between them (r = 0. 708, P = 0.00). TF and VEGF expressions in Ann Arbor stage III and IV (n = 22 and 19) , symptomatic (n = 22) , lactate dehydrogenase (LDH) increased (n = 21) , Eastern Cooperative Oncology Group (ECOG) score 2-4 (n = 12) and extranodal lesions >1 (n = 16) groups were significantly higher than those in Ann Arbor stage II (an = 6) , asymptomatic (an =25) , LDH normal (n = 26) , ECOG score 0-1 ( n = 35) and extranodal lesions ~1 ( na = 31) groups, respectively (all P <0.05). The expressions of TF and VEGF on CD14 + monocytes in high-risk (n = 7) or high-middle-risk (n = 11) groups were significantly increased compared with low-risk (n = 15) or low-middle-risk(n = 14) groups, respectively (all P <0. 01). TF and VEGF expressions in non-remission group before chemotherapy (n = 11) were both obviously higher than those in remission group (an = 36, all P <0. 01) , and after chemotherapy their expressions in remission group were significantly lower than those before chemotherapy (all P <0. 01) , while such significant changes were not observed in the non-remission group ( all P > 0. 05).

CONCLUSIONThe high expressions of TF and VEGF on peripheral CD14 + monocytes can be useful markers in dis-ease assessment, prognosis evaluation and short-term efficacy observation of NHL patients.

OBJECTIVETo observe the analgesic effect and safety of acupuncture-anesthetic composite anesthesia (AACA) in hysteroscopic surgery.

METHODSTotally 93 patients undergoing hysteroscopic surgery were randomly assigned to the intravenous anesthesia group (A group, 30 cases), the AACA group (B group, 32 cases), and the acupuncture combined with intravenous anesthesia group (C group, 31 cases). Patients in Group A were anesthetized by sufentanil combined propofol. Those in Group B were anesthetized by sufentanil combined acupuncture. Those in Group C were anesthetized by sufentanil, propofol combined acupuncture. Yinlian and Ququan (LR8) were needled for patients in Group B and C. The peri-operative mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO2), the surgical time, the recovery time, the sufentanil and propofol dosages, adverse anesthesia reactions were observed. Meanwhile, the OAA/S score, Ramsay sedation score, and Visual Analogue Score (VAS) were also measured.

RESULTSCompared with Group A and C, patients in Group B were awake, with obvious increased OAA/S score (P < 0.01). Ramsay sedation score was significantly lower (P < 0.01).The MAP and HR were elevated (P < 0.05). The patient case of SpO2 less than 85% during the operation decreased (P < 0.05). The incidence of postoperative dizziness was reduced (P < 0.05). Compared with Group A, the propofol consumption decreased in Group C (P < 0.05). There was no statistical difference in the operation time, the sufentanil dosage, VAS score, the incidence of postoperative nause- a and vomiting among the three groups (P > 0.05).

CONCLUSIONSThe patients were awake in AACA. The intraoperative sedation was better than that obtained by intravenous anesthesia. But the analgesic effect was similar to that obtained by intravenous anesthesia.
