Objective To compare the effects of aero bi c exercise training of two different intensities on circadian blood pressure. Methods Twenty-eight sedentary patients with hyperte nsion were randomly allocated into 2 groups, and were treated with aerobic exerc ise training at 20% or 60% of the maximal intensity for 8 weeks, respectively. Not only were the relevant parameters of exercise capacity measured by use of m aximal bicycle ergometer tests, but also was the circadian blood pressure monito red pre-and post-therapy. Results Each paramet er of blood pressure decreased in both groups with similar circadian pattern. Conclusion The aerobic exercise training at 20% an d 60% of the maximal intensity have similar effects on circadian blood pressure.

Objective:To observe the anti-glioma effects of lymphocyte activated by SEC in vivo and probe into therapy effects of SEC combing with operation,radiotherapy and chemotherapy.Methods:Experiment animals were SCID mice.With establishing animal model of glioma xenografted and immunity chimeric model of HuPBL-SCID,we observed the growth curve,survive time.With having operation,radiotherapy and chemotherapy,30 patients suffering from glioma were divided into control group,handle group 1 and 2,and then results were analyzed with MRI.Results:Growth curve shows:A,C and B group produced different suppress against glioma and its suppress rate were 58.5%,46.2% and 36.3%.The first death occurred at the 17th day in control group mice and all mice deaded at the 40th day.Contrasting to this,the first death occurred at the 40th day and 50% mice still were alive in group A until the day that experiment has just finished(60 day).Clinical material showed:The rate of effect(CR and PR) in control group was 40%,while the rate of effects was 50% in handle group 1 and 62.5% in handle group 2.Conclusion:SEC has extramaly potent anti-tumor activity against glioma.SEC combined with operation,radiatherapy and chemotherapy can raise treatment effect in patients with glioma.

Objective To analyze the discourse right construction of China’s medical aid to Africa,so as to provide evidenc?es for improving the effect and sustainable development of China’s medical aid to Africa. Methods The documents of the dis?course right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects,namely confident,charismatic,influential,and dominant. Re?sults China’s medical team made much in the discourse right construction in their aid to Africa,but some China’s medical team members were still too cautious and too low?key. China’s medical team gained the trust of the people of Africa,but the lan?guage communication difficulties still hampered in China’s medical aid to Africa. Chinese medical team were widely praised by the African society,but in the west,some African media,even China’s media still neglected to report China’s doctors. China’s international discourse right were greatly improved,but western countries still dominated the public opinion. Conclusion Chi?na should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

Objective To observe the changes of CD_(28) and soluble CD_(27)(sCD_(27)) among HIV-1-infected Chinese patients receiving highly active antiretroviral therapy(HAART) and to explore their clinical significance.Methods The HIV-RNA viral load(VL) and cell counts of CD_3~+CD_4~+,CD_3~+CD_8~+,CD_4~+CD_(45)RA~+CD_(62)L~+,CD_4~+CD_(28)~+,CD_8~+CD_(28)~+ and the content of sCD_(27) were determined in 28 cases of HIV-1-infected patients at the baseline and 12,24 and 48 weeks respectively after the treatment with three drug regimens based on two nucleoside reverse transcriptase inhibitors(NRTIs) and an Non-NRTI(NNRTI) for 1 year.Results The average of HIV-RNA VL before the treatment was 5.25 logs,and decreased to 3.30,1.92 and 1.74 logs after the treatment for 12,24 and 48 weeks respectively.The cell counts of CD_3~+CD_4~+,CD_3~+CD_8~+,CD_4~+CD_(45)RA~+62L~+,CD_4~+CD_(28)~+,CD_8~+CD_(28)~+ before the treatment were(236?85),(917?345),(58?15),(175?63) and(285?87) cells/?l,and changed into(327?112),(803?343),(114?25),(286?132) and(387?201) cells/?l after the treatment for 48 weeks respectively.The content of sCD_(27) decreased from(475?123) U/ml to(174?77) U/ml after the treatment for 48 weeks.The HIV RNA VL had significantly negative correlation with cell counts of CD_4~+T,CD_4~+CD_(28)~+ and CD_8~+CD_(28)~+,and there was positive correlation between HIV RNA VL and the level of sCD_(27).Conclusion The immune reconstitution and activation depend on the efficacy of antiretroviral therapy.The HIV RNA VL and cell counts of CD_4~+T are the representative parameters of immunologic and viral responses of HAART.The cell counts of CD_4~+CD_(28)~+ and CD_8~+CD_(28)~+ and their percentages show concomitant changes with viral load,and play an effective role in the progression and prognosis of AIDS.The level of sCD_(27) is positively correlated with HIV RNA VL and negatively with counts of CD_4~+T cell.The detection of sCD_(27) by enzyme linked immunosorbent assay(ELISA),which is much more convenient and cheaper than RT-PCR and flow cytometry,may serve as an important parameter to judge the pathogenetic condition of HIV-1-infected patients and to examine the therapeutic effects of HAART in the medical resource-limited area.

Objective To determine the effects of a 12-week aerobic exercise program on brachial-ankle pulse wave velocity ( baPWV) in sedentary and under-exercised healthy older adults. Methods A total of 35 sedentary and unfit but healthy older adults with mean age of 74.7 years were randomly assigned to a progressively increased intensity aerobic exercise group ( n = 17) or a control group ( n = 18). The exercise group performed aerobic exercise 3 times each week for 12 weeks. The control group didn't participate in the exercise program. Heart rate,blood pressure and baPWV were evaluated at admission to the aerobic exercise program and at the end of the 12 weeks in both groups. Results The mean baPWV in the aerobic exercise group decreased from 15.88 m/s to 14.62 m/s after exercise, a significant reduction. Blood pressure in the exercise group showed a decrease which was not significant. No significant improvement was identified in the control group. Conclusions Only 12 weeks of aerobic exercise with progressively increased intensity can improve arterial elasticity in sedentary and unfit older adults.

Objective To understand the the current situation of the slogans in the schistosomiasis health education from the linguistic aspect.Methods Sixty-two slogans in the schistosomiasis health education were collected,then the rationality and validity of them were analyzed from two aspects :the language form and the semantic content.Results Most of the slogans had the appropriate language form and the rational semantic content,they could propagandize the policy and educate the people very well,but there were still some slogans had the inappropriate language form or have the irrational semantic content and so on.Conclusion In order to make the slogans in the schistosomiasis health education more effective,we should attach importance to the language form and the semantic content of them.

Objective: To explore behavioral problems of deaf students.Method:138 students (92 boys and 46 girls) were investigated and assessed by EMBU, the inventory for family backgrounds and Rutter Children Behavior Checklist, and their academic achievements were evaluated by their semester exams.Result:The detected rate of behavior problems was 61.6% by the teacher checklist. The correlation analysis showed that behavior problems in deaf students (especially in boys) correlated moderately with age, sex, academic grades, part of factors in EMBU and education (r=0.35～0.55,P

The study examined the association between calcified liver metastases and the histopathology of the primary colorectal carcinoma in Chinese. The clinical, pathological and CT data were retrospectively analyzed in 210 patients (mean age: 54.2 years) with liver metastases from colorectal carcinoma. Plain CT scanning and contrast-enhanced scanning were performed in all the patients. For the contrast-enhanced examination, iohexol was injected by using a high pressure syringe at a flow rate of 2.5-3.0 mL/s. The arterial phase lasted approximately 25 s and the portal venous phase about 60 s. All patients had no history of chronic liver diseases and had never received interventional treatments. χ(2)-test was used to analyze the rate of calcification in the liver metastasis from colorectal cancer of different differentiation degrees. Among the 210 cases of liver metastases, 22 patients (10.5%) were found to have calcified liver metastases on CT scan. Two patients with calcified liver metastasis received lumpectomy and developed calcification in recurrent tumors. Another two patients had calcification in newly developed tumor masses. And the calcification in the newly developed masses was similar to that of their primary counterparts in terms of morphology and distribution. On the enhanced CT scan, the tumors exhibited no enhancement during hepatic arterial phase and showed slight rim enhancement during portal venous scan in the 22 cases. The calcification became obscure on contrast-enhanced scans. Histopathologically, the primary tumors were well-differentiated adenocarcinoma in 6 cases, moderately-differentiated adenocarcinoma in 10, poorly-differentiated adenocarcinoma in 4 and mucinous adenocarcinoma in 2 among the 22 cases. No statistical correlation was noted between the incidence of calcified liver metastasis and the pathological subtypes and differentiation degrees of the primary colorectal carcinoma. It was concluded that calcified liver metastases may result from colorectal adenocarcinomata of different differentiation degrees or mucinous adenocarcinomata in Chinese population. There is no correlation between calcification of liver metastases and the pathological subtype of the primary colorectal carcinoma in Chinese, which is different from the findings that calcified metastases were associated with colorectal mucinous adenocarcinoma in other ethnic groups.

Objective To investigate the association between the three single nucleotide polymorphisms (SNP) in angiotensin Ⅱ type one receptor (AT1R) gene with coronary artery disease (CAD) in Chinese Han nationality.Methods Extracted DNA and RNA samples of peripheral blood white cells from 192 CAD patients and 189 healthy individuals in Jan 2011 to Oct 2013 from the general hospital of the PLA Rocket Force.Designed primes and the three SNPs as rs6801836,rs2675511 and rs5182 of AT1R gene were analyzed with allele-specific fluorogenic oligonucleotide probes in an assay combining extension and hybridization.Results The genotype and allele frequencies of the three SNPs were not significantly different between the control group and CAD group (x2 =0.047～2.226,all P＞0.05).The major haplotype constructed with linkaged rs6801836 and rs5182 was TT.The frequency of every haplotypes showed no significantly difference between the two groups (x2 =0.025～1.020,all P＞0.05).Conclusion The three polymorphisms of AT1R gene studied in this work showed no association with CAD susceptibility.

Objective To study the effectiveness of microwave ablation in treating HCC.Methods A total of 98 nodules in 56 cases of HCC were treated via appropriate puncture approach ac-cording to the volume, amount and site of tumor nodules. Results Only 1 patient failed to finish treatment since he could not suffer the pain. The other 55 patients finished without a hitch. Clinical and imaging findings were analyzed for change of physiology. Conclusion The microwave ablation is effective for the treatment of HCC. Such therapy can be important supplement of direct surgical man-agement. Its effect mainly depends on accurate puncture approach and enough diametric range. Mean-while, reasonable puncturing method should be selected.
