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 investigate the risk factors associated with early mortality of the rapid two-stage arerial switch operation, which has a significantly higher overall mortality than that of ASO procedure for D-TGA with a intact ventricular septun. Methods The data we reviewed involving patients who underwent rapid two-stage switch operations from September,2002 to September, 2007 in our center, 13 patients were male and 8 were female, their age at operation ranged from 29 to 250 days afer birth, and the body weight was 3.5 to 7 kg. Chi-squared test and multivariant logistic regression methods were used for the analysis of demographic data, pre-diagnosis information, operation data, interval data combined with the operation time,left ventricle training condition, and the early post-operative outcomes. Results The operative mortality was high at initial stage, and then decreased gradually. The logistic multivariant regression analysis indicated that the mortality of left ventricular training operation was associated with the diameters of BT shunt ( P =0.003 ); the mortality of two-stage switch was associated with feminie ( P = 0.006 ) and pre-operative p. LV/RV ( P ＜ 0.001 ). Conclusion Patients with transposition of the great arteries and intact ventricular septum who missed the optimal time for switch operation should receive rapid two-stage switch operations, which provide an opportunity for the correction of the deformity. The key factor associated with the success for operation was good in heart function after left ventricular training.

Objective To study the effects of B cells from lupus prone Triple congenic (TC) mouse model on the differentiation and development of T cell subsets. Methods The spleen size and B cell numbers were measured, and surface CD40, CD86 and Ⅰ-Ab molecules on B cells as well as CD4+T cell subsets were detected using flow cytometry when the spontaneous systemic lupus erythematosus (SLE) model TC mice and control B6 mice were 6 months old. In addition, the chimera of TC B cells and B6 CD4+T cells or chimera of B6 B cells and B6 CD4+ T cells were transferred into B6.Rag-/- mice via intravenous injection. Then, T cell subsets in the spleen of recipient B6.Rag-/-mice were observed 7 days after cell transplantation. Results TC mice had significantly bigger spleen [(5337±934) mg] and more CD19+B cell number [(276.0±48.7)×107] than control B6 mice [spleen weight: (91±4) mg; B cell number: (6.4±0.3)×107](P<0.01). TC mice showed markedly increased CD40 [MFI (63.6±3.1)], CD86 [(MFI (18.96±0.44)] and Ⅰ-Ab [MFI (637±41) on spleen B cells compared with that of B6 mice [CD40 MFI: (36.6 ±2.0); CD86 MFI: (14.26 ±0.19); Ⅰ-Ab MFI: (307 ±23)] (P<0.01). In addition, TC mice revealed notably more Th1 subset [(36.54 ±4.22)%] in spleen than B6 mice [Th1 subset: (19.90±0.10)%] [P<0.01], but both strains had equivalent percentages of Th17 and IL-21+CD4+T cell populations (P>0.05). The recipient B6.Rag-/-mice transplanted with TC B cells had significantly more Th1 subset [(54.1±2.8)%] and IL-21+CD4+T cell population [(14.3±1.0)%], but less Th17 subset [(2.05±0.09)%] in spleen than the recipient B6.Rag-/-mice administered by B6 B cells [Th1 subset: (39.5±1.1)%; IL-21+CD4+T cell population:(7.5±1.2)%;Th17 subset:(6.45±1.10)%](P<0.01). Conclusion The B cells of lupus-prone TC mice exhibit a markedly hyper-activation in spleen, and promote CD4+T cells differentiation preferentially into Th1 subset and IL-21+CD4+T cell population, which may further contribute to SLE pathogenesis.

Objective　To probe into roles of hCKLF-1 in the development of systemic lupus erythematosus in BXSB mice in vivo.Methods　The recombinant eukaryotic expression plasmid for hCKLF-1 (pCDI-hCKLF-1) was transferred and expressed in lupus-prone BXSB mice with the technique of muscle-mediated transgene by electric pulse;the levels of serum IgM and IgG anti-DNA antibodies as well as serum BUN and urine protein were detected.Results　hCKLF-1 expression in vivo did not make any effects on the levels of IgM and IgG anti-DNA antibodies in female and male BXSB mice,but markedly enabled abnormal elevation of urine protein in male BXSB mice in short time,suggesting its ability for accelerating glomerulonephritis.Conclusion　hCKLF-1 may be one of inflammation mediators,playing an important role in the lupus glomerulonephritis of male BXSB mice,and its target cells may be monocyte and macrophage.

Objective To review and sum up experience of surgical repair of single ventricle. Methods Since January 1973 to December 1999, 47 patients with single ventricle have been repaired. Right ventricle type was 17 patients, left ventricle type was 14, and unrecorded type was 16. Surgical procedure consisted of pulmonary banding 1, Fontan operation 23, and bidirection superior cavopulmonary anastomosis 23. Results Seven patients died. The motality was 15%. There was no death in bidirection superior cavopulmonary anastomosis patients. Conclusion For the single ventricle, early surgical intervention is required to prevent pulmonary congestion and severe cyanosis. The bidirection superior cavopulmonary anastomosis can improve single ventricle function secondary to pressure and volume load to decrease surgical mortality and to minimize the risk factors for subsequent Fontan operation.

Conclusion Simvastatin combined with LMWH have good effect in the treatment of acute myocardial infarction.

AIM:To study the microRNA profiling in the serum of insulin-resistant mice and the mechanism of insulin resistance induced by related microRNAs.METHODS:A high-fat diet was used to induce insulin resistance model in KM mice.The microRNA profiling in serum of insulin-resistant and normal mice was analyzed by microarray chip and were validated by real-time PCR.miRanda data base was used to forecast target genes.miRBase was used to obtain the se-quences of related microRNAs, based on which protein interactions were predicted using the online analytical tool STRING. RESULTS:In serum of insulin-resistant mice, the expression of miR-125, miR-126, miR-143, miR-30a, miR-199a, miR-127, miR-184, miR-30e, miR-134, miR-195, miR-206, miR-429, miR-212, miR-362, miR-382, miR-154 and miR-466h was significantly up-regulated.miR-211, miR-504, miR-877 and miR-1930 were significantly down-regulated. miR-143 associated with insulin resistance was able to bind to 3'-UTR of fat mass and obesity-associated protein (FTO), and FTO was found to interact with Rpgrip1l, Tmem18, Mc4r, Npy, Hhex, Tcf712, Cdkal1, Slc30a8, Igf2bp2 and Tha-da.CONCLUSION:Twenty-one microRNAs in the serum of insulin-resistant mice induced by a high-fat diet are signifi-cantly different from those of normal mice, in which 17 kinds were significantly up-regulated.miR-143 closely related to in-sulin resistance is able to regulate FTO protein expression, which interacts with other 10 proteins associated with the occur-rence and development of diabetes.The results are also useful for further study of the molecular mechanisms in insulin re-sistance.

Dynamin-related protein 1 (Drpl) is a major protein for regulating mitochondrial fission.Its activity is associated with the post-translational modification,mainly including phosphorylation,ubiquitination,sumoylation,and S-nitrosylation.During the cerebral ischemia,Drpl is activated and translocates from the cytoplasm to the mitochondrial outer membrane,mediates mitochondrial fission and eliminates damaged mitochondria.Drpl plays the important roles in the pathological processes of ischemic neuronal apoptosis,necrotic apoptosis,and mitophagy.Excessive mitochondria fission or accumulation of damaged mitochondria will aggravate neuronal injury.

Objective To evaluate the concordance on cardiac index (CI) measured with arterial pressure based cardiac output (APCO) and pulmonary artery catheter (PAC) during cesarean section in parturients with congenital heart disease combined with severe pulmonary hypertension.Methods Forty-five congenital heart disease combined with severe pulmonary hypertension parturient who scheduled for cesarean section were selected,APCO and PAC were used for cardiac output and other parameters of hemodynamics monitoring during operation in all patients.Continuous epidural anesthesia was performed.CI was recorded immediately before epidural administration (T1),at 5 and 10 min after epidural administration (T2,T3),immediately before delivery (T4),and at 2 and 5 min after delivery (T5,T6).The correlation of CI between APCO and PAC (A-CI and P-CI,respectively) was tested by Pearson correlation analysis and agreement test.Results The P-CI was significantly higher than A-CI,there was statistical difference (P ＜ 0.05).Compared with T1,no significant differences between A-CI and P-CI were found at T2-T4 and T6 (P ＞ 0.05),The A-CI at T5 [(4.5 ± 1.1) L/(min·m2) vs.(4.2 ± 0.8) L/(min ·m2)] and P-CI [(6.2 ± 1.5) L/(min·m2) vs.(5.4 ± 1.2) L/ (min· m2)] were significantly higher,there were statistical differences (P ＜ 0.05).The correlation analysis showed that there was positive correlation between A-CI and P-CI at T1-6 (r =0.931,0.955,0.945,0.892,0.960,0.913 ; P ＜ 0.05).Bland-Altman analysis showed poor agreement between CI measured with the two methods.Conclusion CI value obtained with APCO agrees poorly with that obtained with PAC during cesarean section in parents with congenital heart disease combined with severe pulmonary hypertension,but agrees well in monitoring the changing trend of CI.
