Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

[Objective]To investigate the genetic polymorphisms of the CYP2C19 gene in the elderly Chinese Han populations of Guangzhou,and compare the frequencies of CYP2C19 gene polymorphisms in different populations,in order to provide accurate data for the appropriate prescription.[Methods]To detect the genetic polymorphisms of the CYP2C19 gene by the DNA microarray,and compare the frequencies of CYP2C19 gene polymorphisms in Chinese Han populations from different areas and the different races.[Results]There were 2312 case samples in our study. The allele frequencies of CYP2C19*1,CYP2C19*2 and CYP2C19*3 were 64.27%,30.75%,and 4.98%,respectively. As the genotype,EM(*1/*1)was 41.44%(n=958),IM(*1/*2,*1/*3)was 45.67%(n=1056),and PM(*2/*2,*2/*3 and*3/*3)was 12.89%(n=298). The ratios of EM and IM in Chinese Han populations from different areas and all the subtypes of the CYP2C19 genotype in different minority were statistically significant. As the races,there were difference in all the subtypes of the CYP2C19 genotype when Asian populations were compared with white races(P<1304.64)and black races(P<0.01),which was also statistically significant.[Conclusions]The distributions of the CYP2C19 gene polymorphisms were significantly different in Chinese han populations and in different races,and the main subtypes of the CYP2C19 genotype in the elderly of Chinese han populations were IM and EM,which is beneficial for prescribing appropriate in the elderly populations.

Objective To conduct mutation screening of SCN1A 3′ untranslated region (UTR) on Dravet syndrome (DS) patients without mutations in the SCN1A coding region and promoter region, and functional analysis of the variant from DS patients.Methods Twenty-eight DS patients without mutations in the SCN1A coding region and promoter region were screened for SCN1A 3′ UTR mutations using PCR and direct sequencing.Functional analysis of the detected mutation was done via luciferase assay, mRNA stability analysis and RNA electrophoretic mobility shift assay (RNA-EMSA).Results A novo variant (c.*20A>G) in SCN1A 3′ UTR was found in one DS patient.The variant (c.*20A>G) reduced the luciferase gene xpression by 30% through increasing the affinity of pluripotent embryonal carcinoma cell line NT2/cytoplasmic protein binding and reducing luciferase gene mRNA stability (t=8.5,P<0.01).Conclusions A functional variant was detected from one patient with DS.This variant negatively regulated the gene expression by increasing the affinity of pluripotent embryonal carcinoma cell line NT2/cytoplasmic protein binding and reducing mRNA stability.

OBJECTIVETo establish a stable high red fluorescent protein (RFP)-expressing orthotopic transplantation nude mice spontaneous metastasis model of pancreatic cancer.

METHODSStable high RFP-expressing cells SW1990-RFP were injected subcutaneously into mice to establish subcutaneous implantation model. Fluorescent tumor piece from subcutaneous was transplanted into the body of the pancreas to establish surgical orthotopic implantation model. The growth of primary tumor, metastasis and micrometastasis were assessed by whole-body fluorescence imaging system.

RESULTSTwelve RFP orthotopic transplantation nude mice metastasis models of pancreatic cancer were established successfully, the percentage of success rate was 100%. RFP-labeled pancreatic cancer growth could be monitored in real time way. The micrometastasis of primary lesions were detected in early stage with whole-body fluorescence imaging system.

CONCLUSIONSThe RFP orthotopic transplantation nude mice metastasis model of pancreatic cancer is stable and reliable, and can be observed dynamically in vitro in a noninvasive way, with much higher sensitivity and specificity.

To investigate the feasibility of using recombinant adeno-associated virus type 1 vector as prophylactic vaccine against HPV16 infection, rAAV1-mod. HPV16L1, the recombinant AAV1 vector containing codon-modified HPV16 L1 gene, was constructed. C57BL/6 mice were immunized with purified rAAV1 vector through intramuscular and intranasal inoculation routes, and the titer of neutralizing antibody was determined by neutralization assay based on HPV16 pseudovirus. The result shows that the single dose of rAAV1-mod. HPV16L1 can induce specific neutralizing antibody in serum through both inoculation routes. Compared with intranasal group, intramuscular group can induce higher titer of neutralizing antibody. Eliciting strong and prolonged neutralizing antibody in serum, the rAAV1-mod. HPV16L1 is one of promising HPV16 prophylactic vaccine candidates.

OBJECTIVETo study the protective effect of Shenxiong injection on the cerebral ischemia-reperfusion injury of senile rats.

METHODTotally 108 Sprague-Dawley (SD) rats were randomly divided into the sham operation group, the model group, the Ni-modipine group and Shenxiong injection groups (low, middle, and high doses). The rat brain ischemia-reperfusion model was established by the middle cerebral artery occlusion (MCAO) method in rats, in order to observe the effect of Shenxiong injection on neurological score and brain infarct volume of rats with cerebral ischemia-reperfusion injury, and determine the contents of NOS, NO, SOD, MDA and LDH in brain tissues. The contents of TNF-alpha and IL-1beta levels in brain tissues were measured by enzyme-linked immunosorbent assay (ELISA) method.

RESULTShenxiong injection could significantly decrease neurological score, injury degree of brain tissues and brain infarct volume of rats with cerebral ischemia-reperfusion injury, increase the vigor of SOD, decrease the levels of MDA, NO, NOS and LDH, and inhibit IL-1beta and TNF-alpha expressions.

CONCLUSIONShenxiong injection has the obvious protective effect on the brain ischemia-reperfusion injury in rats. Its mechanism may be related to the improvement of neurological function, the reduction of free radical injury, and the inhibition of inflammation factor expression.

Objective To evaluate the immune potency of recombinant adenovirus combined with rAAV1 vector expressing HPV16L1 protein in mice. Methods The rAdV and rAAV1 vector containing cedon-medified HPV16L1 gene was constructed using Admax and AAVmax packaging system respectively. C57 BL/6 mice were immunized with purified rAdV and rAAV1 vector through intramuscular and intranasal inoculation routes,and the titer of neutralizing antibody was determined by neutralization assay based HPV16 pseudovirus. Results Intramuscular immunization by rAAV1-med. HPV16L1 or combined with tAd-reed. HPV16L1 can induce higher titer of neutralizing antibody in serum than that of other groups. The titer of neutralizing antibody of intranasal groups is significantly lower than that of intramuscular group,although the prime-boost atrategy using in intranasal group was effective to enhance the specific humoral immunity. Conclusion The rAAV1-med. HPV16L1 combined with tAd-reed. HPV16L1 can induce higher titer of neutralizing antibody in serum through intramuscular route than that of other groups at the 16th week after the first immunization.

OBJECTIVETo investigate the expression of Csk-binding protein (CBP) in esophageal carcinoma and its association with the tumorigenesis and progression of esophageal cancer.

METHODSRT-PCR and Western blotting were employed to determine the expressions of CBP at the mRNA and protein levels in 50 pairs of fresh esophageal carcinoma tissue and the adjacent normal tissues.

RESULTSCBP mRNA and protein expressions in normal tissues were 1.43- and 1.28-fold higher than those in the cancer tissues, respectively (P<0.05). The expressions of CBP mRNA and protein were positively correlated (P=0.015). The decreased expressions of CBP were significantly correlated to lymph node metastasis of esophageal cancer (P<0.05).

CONCLUSIONThe expression of CBP gene is decreased in esophageal carcinoma, which might contribute to the tumorigenesis and progression of this malignancy.
