Objective To explore the genetic interactions between angiotensin-convertingenzyme (ACE) I/D and methylenetetrahydrofolate reductase (MTHFR) C677T genotypes in middlecerebral artery stenosis (MCAS) among the asymptomatic residents in Foshan area of China. MethodsUsing a cluster sampling method, 2500 subjects were randomly selected from the residential communitiesof Rongqi town of Foshan area, Guangdong Province. By means of epidemiological questionnaire survey,physical examination, examination of the biochemical markers and transcraniai color Doppler (TCD), 897eligible subjects (306 males and 591 females) were selected from this population and subsequentlydivided into MCAS group and control group according to the TCD results. ACE and METHFR genepolymorphism analyses were conducted using amplified fragment length polymorphism-polymerase chainreaction (AFLP-PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP). Chi-square test, t test, Mann-Whitney test and logistic regression analysis were used to analyze the data. ResultsGender, age, waist-to-hip ratio (WHR) and Ⅱ+CC genotype distribution in the subjects with MCAS weresignificantly different from those in the control subjects. Logistic regression analysis identified age andACE Ⅱ+ MTHFR CC genotype as the independent factors that affected MCAS. Conclusion There aregenetic interactions between ACE I/D and MTHFR C677T genotypes, and the ACE Ⅱ+MTHFR CCgenotype is an independent genetic factor for protection against MCAS in the asymptomatic residents inFoshan area of China.

Objective To investigate the prevalence and risk factors of asymptomatic intracranial artery stenosis in middle-aged and elderly population in the community of Foshan city,Guangdong province. Methods Subjects from residential communities were chosen through Cluster sampling method. Physical data and history were collected. Serum fasting glucose, total cholesterol and triglycerides concentrations were tested with venous blood samples. Intracranial artery stenosis was diagnosed by transcranial Doppler(TCD). Data was analyzed by the software SPSS 18.0.Results 1405 subjects met the inclusive criteria, among which 163(11.6%)were found one(7.4%)or more(4.2%)stenotic arteries, and the standardized rate was 10.3%. 9.89% of the SICA, and 3.05%, 2.29%, 1.59%, 1.38%, 0.89% of basilar artery, middle cerebral artery, anterior lerebral artery,vertebral artery, posterior cerebral artery were found stenotic respectively. Data from the age-stratified analysis showed that the prevalence in these above 70(27.8%)was significantly higher than that under age 70(7.5%)(P=0.000). Single factor and logistic regression analysis demonstrated the history of diabetes mellitus and elevated systolic pressure present were significantly different between stenofic group and the non-stenotic group(P=0.000, P=0.000), which were the independent risk factors of asymptomatic stenosis of intracranial arteries(OR= 2.362,95%CI:1.194-4.674; OR= 1.024,95%CI:1.016-1.031). Conclusion Comparatively high prevalence of asymptomatic intracranial artery stenosis in middle-aged and aged community population was found in the Southern part of China,especially among the age group above 70. History of diabetes and elevated systolic pressure seemed to be the independent risk factors of asymptomatic stenosis of intracranial arteries.

Objective To establish an automatic synthesis method for 11C-carfentanil (CFN) as an novel opiate receptor radioligand and study its biodistribution in rats. Methods 11C-Triflate-CH3 was bubbled into 0.5 mg precursor desmethyl-CFN (which was dissolved in 0.15 ml DMSO) to generate 11C-CFN in a V-tube at room temperature. Sep-Pak C2 column was used for purification of 11C-CFN, which was eluted by 3ml binary system aqueous solution, 10 ml water thrice, and then I ml ethanol. The biodistribution (% ID/g) of 11C-CFN in SD rats was studied. SPSS 13.0 was used for statistical analysis. Non-normal distribution data were analyzed using nonparametric test. Results The synthesis time for 11C-CFN was 20 min (end of bombardment, EOB). The synthesis yield was (35.5 ± 2.2) % on average (n = 12, uncorrected)with the radiochemical purity over 98%. Biodistribution study in rats showed that the tracer had a high brain uptake, rapid blood clearance, and a metabolic pathway via liver and kidney. The highest tracer uptake was in thalamus (4.26 ± 0.89) % ID/g and striatum (4.05 ± 1.08) % ID/g at 5 min after injection, followed by cerebral cortex (2.63±0.89) %ID/g, pons (2.26 ±0.57) % ID/g, hippocampus (2. 17 ±0.55) %ID/g and cerebellum (2. 15 ±0.39) %ID/g. Conclusions The automatic synthesis of 11C-CFN is fast and reliable, and this radioligand can be used for opiate receptor imaging.

OBJECTIVETo evaluate the therapeutic potential of marrow-derived cardiac stem cell (MCSC) transplantation after myocardial infarction (MI) in rats.

METHODSMCSC were selected from the marrow mesenchymal stem cell (MMSC) of male SD rats by single-cell cloning culture. MI was induced by left anterior descending artery ligating in female SD rats. Equal volume PBS, MMSC and MCSC were transplanted at the border zone of the infarct one week after MI. Cardiac function was assessed by echocardiography at four weeks after cell transplantation. The hearts were removed and morphological changes of scar tissue were examined with HE staining and Masson trichrome staining, VEGFR-1(+) capillary vessels were labeled with immunohistochemical staining. Scar area and vessel density were measured by image analyzer. MCSC containing Y chromosome were examined using in situ fluorescent hybridization, and cardiomyocyte cTnT expression was also analyzed.

RESULTSCardiac transcription factor Nkx2.5 was expressed at low level in c-kit(+) MCSC. Four weeks after cell transplantation, left ventricular fractional shortening and ejection fraction were significantly higher while scar area was significantly lower in MCSC group compared to MMSC group and control group. cTnT was expressed in cells containing Y chromosome and these cells were connected with myocardium of recipient rats in the rats transplanted with MCSC. Vessel density around the infarcted tissue in MCSC group was similar as that in MMSC group and significantly higher than that in control group.

CONCLUSIONMSCS could effectually differentiate into functional cardiomyocytes at the border zone of the infarct, and MCSC transplantation post MI significantly improved cardiac functions and promoted angiogenesis.

OBJECTIVETo study the features of hypertension and vessel endothelium functional parameter in people living at the community level as well as the risk factors of hypertension. Differences of angiotensin II (Ang II ), prostacyclin (PGI2) and nitric oxide (NO) among normal group and three hypertension groups were also studied.

METHODSBy cluster sampling, 1134 adult Han people were selected from the residential communities. Medical history was documented and measurements of body height, body weight, waist circumference, hip circumference and blood pressure were performed. Serum NO levels were determined by cadmium reduction method while plasma Ang II and PGI2 concentration were determined by radioimmunoassay. SPSS 13.0 was used for data analysis.

RESULTSThe total ratio of hypertension from people living at the community was 44.5%, with the standardized prevalence of hypertension as 15.3%. With the increase of age, the prevalence of hypertension also increased. Overweight and obesity seemed to be independent risk factors for hypertension. History of smoking and drinking and gender did not enter the logistic equation for hypertension. The amount of plasma Ang II concentration of the three hypertension groups was significantly lower than that in the normal group while the lowest group appeared to from the one that hypertension was under control. The NO and PGI2 levels of the two groups whose hypertension had been known were significantly higher than in the normal group while the difference between the group whose hypertension had not been measured and the normal group was not found.

CONCLUSIONThe prevalence of hypertension had been increasing. Control of body weight seemed to be a useful way for prevention of hypertension. We assumed that the negative feedback regulation of renin-angiotonin-aldosterone system in hypertension patient still existed which called for the research on the mechanism of hypertension.

OBJECTIVETo compare the therapeutic effects between acupuncture and electric stimulation on post-stroke dysphagia on the basis of rehabilitation training.

METHODSNinety-seven patients with post-stroke dysphagia were randomly divided into an acupuncture group (group A, n = 32), an electric stimulation group (group B, n = 35) and a rehabilitation training group (group C, n = 30). In group C, the conventional therapy (conventional therapy of neurologic internal medicine and rehabilitation training) was applied. In group A, the combination of conventional therapy and acupuncture was applied. The acupoints of Fengchi (GB 20), Futu (LI 18), three-needles on the forehead, etc. were selected. In group B, the combination of conventional therapy and electric stimulation was adopted. Watian drinking water experiment, stethocatharsis function scoring and video fluoroscopic swallowing study (VFSS) were used to evaluate swallowing function of patients.

RESULTSAfter treatment, the total effective rate was 96.95 (31/32) in group A and was 94.3% (33/35) in group B, which was superior to that of 66.7% (20/30) in group C (P < 0.01). After treatment, the swallowing function in group A, group B and group C were all improved significantly as compared with that before treatment (all P < 0.05). After treatment, the effects in group A and B were superior to that in group C (both P < 0.05).

CONCLUSIONThe therapeutic effect of the combination of either acupuncture or electric stimulation with rehabilitation training is better than that of simple rehabilitation training. The efficacy on dysphagia is equal between acupuncture and electric stimulation.

OBJECTIVETo investigate sperm DNA integrity in male infertility patients with hepatitis B virus (HBV) infection.

METHODSThis study included 90 infertile men with HBV infection (group A), 82 infertile men without HBV infection (group B) and 70 normal fertile men (group C). We detected sperm DNA integrity among the subjects, including DNA fragmentation index (DFI) and high DNA stainability (HDS), by sperm chromatin structure assay (SCSA), and compared them among the three groups.

RESULTSDFI was higher in group A ([28.17 +/- 13.06]%) than in B ([26.64 +/- 9.79]%) and C ([15.67 +/- 4.73]%), significantly higher in A and B than in C (P < 0.05) but with no significant difference between A and B (P > 0.05). HDS was higher in group A ([10.83 +/- 5.601]%) than in B ([9.04 +/- 3.48]%) and C ([8.04-2.25]%), with significant difference between A and C (P < 0.05).

CONCLUSIONSperm DNA integrity of infertile males is significantly different from that of normal fertile men, and infertility with HBV infection further impairs sperm DNA, which is manifested by abnormal sperm nuclear maturity.
