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.

Objective To compare the effect of the McKenzie method and traditional manipulation in the treatment of patient with cervical spondylotic radiculopathy. Methods Seventy-two patients (42 women and 30 men with an average age of 42.60?13.73 years ) were randomly divided into 2 groups: an observation group and a control group.

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.

Objective To investigate the expression ofpodocalyxin(PCX) in patients with diabetic nephropathy (DN) and its clinical significance.Methods A total of 68 patients with DN were enrolled as DN group.Another 20 healthy person were selected as control group.The patients with DN were divided into three sub-groups:normal albuminuria group(＜ 30 mg/g,group A),microalbuminuria group(≥30 mg/g but ＜ 300 mg/g,group B) and macroalbuminuria group (≥ 300 mg/g,group C).The level of urinary PCX was measured with enzyme-linked immunosorbent assay.Results The level of urinary PCX,serum creatinine and blood urea nitrogen in DN group was higher than that in control group [(27.44 + 6.87) μ g/L vs.(3.52 +1.13) μ g/L,(154.82 ± 11.54) μ mol/L vs.(82.56 ± 5.71) μ mol/L,(8.79 ± 0.58) mmol/L vs.(4.23 ± 0.34)mmol/L,P ＜0.01].The level of urinary PCX in group A,B,C was (18.04 ±4.12),(23.58 ±5.43),(32.18 ± 6.05) μ g/L,and there was significant difference among three groups (P ＜ 0.05).The level of serum creatinine and blood urea nitrogen was (138.54 + 8.66),(142.16 ± 11.74),(165.13 ± 12.85) μ mol/L and (8.48 ± 0.43),(8.56 ± 0.61),(10.04 + 1.17) mmol/L in group A,B,C,there was no significant difference between group A and group B(P＞ 0.05),but there was significant difference between group A and group C,or between group B and group C (P ＜ 0.05).Conclusion The high-level expression of urinary PCX is found in DN patients,which maybe play a key role in the early diagnosis and assessment of the progression of DN.

Objective To observe the application of modified perfusion device pre-flushing method in double plasma molecular adsorption system (DPMAS) treatment and nursing care effect on patients with liver failure. Methods A retrospective analysis was conducted; 56 patients with liver failure who were consistent with the enrolled standard and admitted to the Surgical Intensive Care Unit (SICU) of Beijing Chaoyang Hospital fromJune 2014 to December 2016 were the objects of the study and their clinical data were collected. Ten patients involving the results of 17 case times from June 2014 to April 2015 were selected as the control group by using the traditional method of pre-flushing, and 46 patients involving the results of 68 case times from May 2015 to December 2016 were chosen as the observation group by using the modified perfusion device pre-flushing method. Both groups adopted effective nursing care cooperation: such as closely observe the changes of symptoms and signs of patients during the peri-treatment period, strengthen psychological care, maintain pipeline properly, and carry out the preventive management of anticoagulation and potential complications. The changes of symptoms and signs in the patients of two groups were observed, the DPMAS pre-flushing time and single time effective treatment time of the two groups were compared, before and 3 days after DPMAS treatment, the changes of serum total bilirubin (TBil), total bile acid (TBA) and its clearance rate, the changes of electrolytes, liver and kidney functions, blood routine and blood coagulation function were observed and compared between the two groups to evaluate and analyze the therapeutic effect of DPMAS.Results In the two groups, there were 56 patients involving 85 case times of DPMAS treatment all successfully completed, and the patients' symptoms and signs were improved significantly. The pre-flushing time of the observation group was obviously shorter than that in the control group (minutes: 29.5±13.1 vs. 38.9±14.7), and the single effective treatment time was obviously longer than that in the control group (minutes: 6.7±1.1 vs. 3.4±0.9,P < 0.05). After treatment, the TBil, TBA, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and albumin (ALB) in two groups were decreased significantly compared with those before treatment, the prothrombin time (PT) was markedly prolonged compared with that before treatment (allP < 0.05), and the degrees of improvement in the observation group were more obvious than those of the control group (butP > 0.05), and urea nitrogen (BUN), creatinine (Cr), hemoglobin (Hb), platelet count (PLT), Na+ and K+ had no significant changes compared with those before treatment (allP > 0.05). The TBil clearance rate [(42.5±15.5)% vs. (32.9±13)%] and TBA clearance rate [(27±8.9)% vs. (17.1±5.8)%] in the observation group were significantly higher than those in the control group (allP < 0.05). There were no adverse events such as electrolyte disturbance, errhysis or bleeding found in the two groups during the treatment. In the study, there were 8 case times with self feeling of skin itching, 8 case times of skin rash, 6 case times of nausea and vomiting, 6 case times of chest tightness, 5 case times of blood pressure dropping phenomena and 4 case times of fever symptoms, and after the symptomatic treatments and nursing intervention, all the above symptoms were relieved or disappeared.Conclusion The modified perfusion device pre-flushing method can effectively elevate the pre-flushing effect and therapeutic effect, it is simple, time-saving, can reduce the economic burden of the patients, thus it is worthy to be used widely in clinic, during the therapeutic process, reasonable and effective nursing measures are practiced, that is the key to guarantee the successful treatment of patients.
