Adaptive response is a topic of general interest in medical research. Utilization of adaptive response has become a new treatment strategy for some diseases, the core of which is to stimulate the mechanisms of body internal protection, to improve the adaptive and anti-injury capability, and to maintain the homeostasis of the body. The existence of adaptive response indicates that the body internal protection can be induced and its key mechanism is the inducement of internal protective factors (internal protective proteins). In this article, some connections between adaptive response and the theory of traditional Chinese medicine (TCM) were discussed, which indicated that adaptive response is much beneficial for explaining some theories of TCM such as correspondence between human and nature, strengthening healthy qi to consolidate constitution, acupuncture theory, adaptogen herbs, and treating disease before its onset, etc. Thus the adaptive response is of great significance for explaining scientifically the connotative meaning of the theories of TCM and for promoting the integration of TCM and western medicine.

Range of motion of the cervical spine of the observation group was significantly improved after the treatment(P

Objective To observe the effects of fluoride on testicular cell cycle and cell apoptosis of male rats.Methods Thirty-two healthy male Wistar rats,weighting 150-180 g,were randomly divided into 4 groups by body weight using random number table,normal sodium (control),the low-dose,medium-dose and high-dose groups(100,200,300 mg· kg-1· d-1 NaF,respectively) by intragastric administration for 90 days,and bodyweight was observed daily.After the last intragastric administration,all rats were killed by cervical dislocation.The testicular cell cycle and cell apoptosis were measured by flow cytometry.Results After 30 days exposure,the difference of body weight between groups was statistically significant(F =3.884,P ＜ 0.05).The body weights in low-and medium-dose groups[(235.00 ± 14.56),(235.44 ± 24.99)g] were significantly increased than that of high-dose group [(206.00 ± 18.16)g,all P ＜ 0.05].There was no significant difference of body weight between the groups at 0,60 and 90 days(F =0.501,0.578,1.893,all P ＞ 0.05).Compared with the control group[(43.10 ± 3.62)％],the percentages of G0/G1 stage cells were significantly increased in all the NaF-treated groups [(57.60 ± 7.26) ％,(52.80 ± 3.20) ％,(73.13 ± 4.08) ％] and the percentages of S stage cells were significantly decreased in all the NaF-treated groups [(10.58 ± 2.58)％,(9.35 ± 0.35)％,(9.55 ± 0.50)％] compared to the control group[(19.23 ± 0.61)％,all P ＜ 0.05].On the other hand,the percentage of G2/M stage cells decreased significantly in high-dose group[(17.18 ± 2.21)％] compared with the control group[(36.34 ± 5.05)％,P ＜ 0.05].The testicular cell apoptosis ratios in all the NaF-treated groups were higher than that in the control group,but only in medium-and high-dose groups[(71.03 ± 2.30)％,(71.90 ± 2.16)％],the difference was statistically significant compared with the control group [(60.80 ± 2.34)％,all P ＜ 0.05].Conclusion Chronic fluorosis can change testicular cell cycle and cell apoptosis and damage the reproductive system.

OBJECTIVE:How to explain and predict individual difference of artificial cochlea so as to evaluate rehabilitative effect of implant has been paid much attention by audiological scholars,clinical physicians,patients,and their relatives. This study was designed to analyze and evaluate rehabilitative status of patients accepting artificial cochlea implantation to investigate the relative influential factors of auditory rehabilitation. METHODS:A total of 28 patients were selected from Department of Otolaryngology Head and Neck,Affiliated Hospital of Qingdao Medical College from June 2002 to April 2008. They were accessed by age,time of rehabilitation training,usage of hearing aids,audiology and aural image before surgery,and NRT monitoring in cochlear implantation so as to observe auditory improvement. The clinical results were analyzed to detect the effect of various factors on auditory rehabilitation. RESULTS:Age,preoperative preparations and good audiology and aural image are important premises for a successful rehabilitation. Longer the time of using hearing aids and language rehabilitation are,and better results will get. NRT response during operation is also an important factor for good auditory rehabilitation. CONCLUSION:The influential factors of auditory rehabilitation after cochlear implant included the age,audition remains,usage of hearing aids,NRT response during operation,and the time after the cochlear implant operation.

The vectors play an important role in gene therapy by transporting the therapy genes into target tumor cells. At present there are mainly two kinds of gene vectors, including biological and non-biological vectors. Biological vectors, including virus, bacteria and stem cells, have good target activity and can efficiently delivery the genes into target tumor cells, but have potential genetic hazards.However, non-biological vectors, including liposomes and nanoparticles, can be simplely prepared with high genetic safety, but they can not transport the genes efficiently. Therefore, establishing safe and effective malignant glioma gene treatment system and finding gene vectors with good target activity become the research focus.

Hyperbaric oxygen may play a role through different mechanisms in improving the prognosis of diabetic foot.

Effects of preconditioning(PC) and praeruptorine C(Pra-C) on intracellular free calcium level(［Ca2+］i) and NO content in hypertrophied vascular smooth muscle cells (VSMC) with hypoxia were studied. ①The aorta VSMC of rats with renovascular hypertension induced by two-kidney-one-clip(2K1C) were isolated and cultured. Fura-2/AM was as a calcium fluorescent indicator. It was seen that Pra-C(20 mg*kg-1*d-1，ig, for 9 weeks from week 9 after 2K1C) and PC (3 cycles of 5 min pure N2 and 5 min 95%O2+5%CO2) antagonisted the elevated activities(higher ［Ca2+］i) induced by KCl and norepinephrine in VSMC with hypo- xia (30 min pure N2). ② In hypertrophied VSMC stimulated by angiotensinⅡ, combination of Pra-C(10 μmol*L-1 for 24 h) and PC enhanced NO content to the normal level in hypertrophied VSMC with hypo- xia. The results suggest that combination of Pra-C and PC have cooperative protection for hypertrophied VSMC with hypoxia injury.
