It simplified the design of hardware and software and improves precision of control system. The chip CC2420 was adopted as the frequency transceiver. The operating system TinyOS which was developed by the University of California at Berkeley was also adopted. Results We accomplished the design of temperature data acquisition module,wireless communication module and power management module,which had many features,such as simple structure,small size and high precision. Conclusion The node has effectively improved the functional reliability of pyrolyzing furnace,giving a solid base to promote the application of WSN technology on medical vehicle.

Objective:To identify the influence of occupational stress on occurrence of hypertension.Methods:A prevalent cohort of 964 male workers employed for at least 3 years with different occupational stress were investigated with Occupational Stress Index, hypertension was diagnosed by WHO criteria of 1996. Results:The occupational stress was a risk factor for hypertension with RR=1.70 and in a dose-effect pattern after adjusted for other factors. In high exposure group, the adjusted incidence density was 12.47/per 1000 person-years with RR=2.99, in the medium exposure group, that was 8.81/per 1000 person-years with RR=2.11, that of low exposure group was 4.17/per 1000 person-years, the differences between different groups had statistic significance. When the length of exposure was more than 10 years, the adjusted incidence of hypertension increased significantly in high and medium exposure groups.Conclusions:Causality between occupational stress and hypertension exist, but it needs long exposure of at least 10 years for occurrence of hypertension.

Objective To propose a grasp torque control based on experimental learning and haptic feedback to facilitate the manipulator in dexterous manipulation.Methods An experience database was built firstly,and then the object was recognized by tactile feedback in the grasp task.If the object had been experitentially grasped,the torque was output based on the database.In case a new object was grasped,the optimal output torque was calculated by iterative learning.Results The experiment showed that the robot hand could find the experiential output torque quickly when encountering the object in database and calculate the torque by iterative learning to achieve grasp task.Conclusion The experiential database grows up when the robot hand learns more and more experience.It can fast output torque like human in the grasp task.

Objective To define the nuclear agrresome formation is determinated by which part of the UL76 of
HCMV. Full-length, conserved N terminal and unconserved C terminal of pUL76 were constructed to eukaryotic ex-pression plasmid pEGFP-N1 . Methods Primers were designed to amplify full-length and different part of pUL76 according to standard sequence of HCMV AD169 which had been submitted to GenBank(FJ527563. 1). These frag-ments were constructed to eukaryotic expression plasmid pEGFP-N1 . The recombinant plasmids were designated pEGFP-UL76,pEGFP-UL76N, pEGFP-UL76C respectively. Double digestion and sequencing were performed to verify the accuracy of recombinant plasmids construction. Empty vector and three recombinant plasmids were transi-ent transfected to HELF and HepG-2 cells respectively. Reverse transcriptation PCR and Western blot were per-formed to detect the RNA and protein expression level respectively. Different nuclear aggresome formations were visualized with an Olympus fluorescence microscopy. Results pEGFP-N1 and pEGFP-UL76N were unable to in-duce nuclear aggresome formation, whereas pEGFP-UL76 and pEGFP-UL76C were able to elicit nuclear aggresome formation. Conclusion The unconserved C terminal of pUL76 is sufficient to induce nuclear aggresome formation.

Objective: To analyze the validity of the lie scale in University Personality Inventory (UPI). Methods: Relationship between choice of lie scale and UPI score , mental health was analyzed by UPI questionnaire of 2958 freshers.Results: Average every student chosed 2.37 lie items. Relationship between UPI score and numbers of the choosed lie items showed negative correlation. Numbers of lie items that was chosen by First class students was fewer than that was chosen by second class students, and numbers of lie items that was chosen by second class students was fewer than that was chosen by third class students.Conclusion:UPI lie scale had lost validity to evaluate attitude of respondent, so UPI lie scale should be revised.

Objective To observe the curative effects of pterygium excision combined with autologous limbal stem cell transplantation in the treatment of primary pterygium.Methods 50 cases (72 eyes) of primary pterygium were selected in our hospital.According to the method of random number table,50 canses were divided into the control group (37 eyes) underwent pterygium excision and the study group (35 eyes) received autologous limbal stem cell transplantation on the basis of the control group,with 25 cases in each,and the efficacy were compare between the two groups.Results The healing time of study group[(3.02±0.37)d] was significantly shorter than in the control group[(6.85±0.48)d](t=2.95,P=0.01) and the recurrence rate (20%) was significantly lower than in the control group (52%) (x2=10.35,P=0.03),and the postoperative complications rate (8%) was significantly lower than in the control group (36%) (x2=13.94,P=0.03).Conclusion Compared with pure pterygium excision,pterygium excision combined with autologous limbal stem cell transplantation in the treatment of primary pterygium has higher clinical efficacy,which can effectively shorten the repair time and reduce recurrence rate,with high safety,so it is worthy of further promotion and application in clinic.

OBJECTIVETo compare the difference in the clinical efficacy on type M prostatitis between the combined therapy of acupuncture and isolated-ginger moxibustion and tamsulosin.

METHODSOne hundred and ten patients of type III prostatitis were randomized into an acupuncture and moxibustion group and a tamsulosin group, 55 cases in each one. In the acupuncture and moxibustion group, acupuncture and isolated-ginger moxibustion were adopted. Two groups of acupoints were selected, named (1) Guanyuan (CV 4), Qugu (CV 2) and Sanyinjiao (SP 6); (2) Yaoyangguan (GV 3), Pangguangshu (BL 28) and Zhibian (BL 54). The two groups of points were used by acupuncture alternatively and only one group was selected a day. Isolated-ginger moxibustion was applied to Guanyuan (CV 4) and Zhibian (BL 54), once a day, 10 treatments made one session, and totally 3 sessions were required. In the tamsulosin group, tamsulosin was prescribed for oral administration, 0.2 mg, twice a day for 1 month. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score and expressed prostatic secretion (EPS) score were observed in the patients of the two groups.

RESULTSNIH-CPSI and EPS scores after treatment were all reduced apparently as compared with those before treatment in the two groups (all P < 0.05). The improvements in the acupuncture and moxibustion group were more obvious than those in the tamsulosin group (all P < 0.05). In 3 months follow-up, NIH-CPSI score in the acupuncture and moxibustion group was reduced apparently as compared with the tamsulosin group (P < 0.05). The curative rate and total effective, rate were 20.0% (11/55) and 85.5% (47/55) in the acupuncture and moxibustion group, and were 3.6% (2/55) and 61.8% (34/55) in the tamsulosin group respectively (both P < 0.05).

CONCLUSIONThe combined therapy of acupuncture and isolated-ginger moxibustion achieves the good effect of relieving the symptoms of type III prostatitis and recovery of EPS, better than those treated with tamsulosin. This combined therapy spresents the better long-term efficacy.

Objective To explore the effect of transcription factor E2F1 on the apoptosis of small cell cancer line H446. Methods Plamid vector- mediated E2F1 small hairpin RNA (shRNA) was used to silence E2F1 in H446 cell. RT-PCR and western-blot assay were used to detect the expressions of E2F1 and Bcl-2. The apoptosis rate in H446 cell line was detected by flow cytometry assay. Result E2F1 protein was suppressed in shRNA1-modified H446 cell. Sgnificant difference of the apoptosis was shown between E2F1 shRNA1 group and the other two groups. Additionaly, the expression of Bcl-2 protein increased in E2F1 shRNA1-modified cell line. Conclusions E2F1 is highly expressed in H446 small cell lung cancer cell line. E2F1 promotes apoptosis of H446 through upregulating Bcl-2 expression.
