Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder and its clinical manifestation including haemangioblastomas of the central nervous system, renal cell carcinoma, haeochromocytomas, and pancreatic cyst. The deletion, mutation and promoter methylation of VHL gene can cause VHL disease. Swine is considered as an ideal model for human disease because of its physiological and anatomical similarity to human. We cloned pig VHL gene that is 2 725 bp in length. VHL highly expressed in adrenal gland, liver, pancreas, heart and testis. We designed 5 shRNAs and screened the most effective interference RNA fragment with a knockdown efficiency of 72%. Porcine embryonic fibroblasts stably transfected with pGenesil-shRNA vector were used as donor cells for nuclear transfer and there was no significant difference of embryo development compared with the control group. Moreover, VHL was efficiently knocked-down with efficiency of 71% in porcine cloned blastocyst, these results lay a solid foundation for constructing the VHL knock-down model of pig.

OBJECTIVETo explore the clinical effect and mechanism of electroacupuncture at Jiaji (EX-B 2) on drug craving of heroin addicts.

METHODSOne hundred and twenty cases of heroin addicts were randomly divided into 4 groups, 30 cases in each. In acupuncture group 1, the Jiaji (EX-B 2) points of T5-T7 and Shenshu (BL 23) were selected with electroacupuncture; in acupuncture group 2, Neiguan (PC 6), Shenmen (HT 7) and Zusanli (ST 36) etc. were selected with electroacupuncture; in simulation group, Zusanli (ST 36) and Sanyinjiao (SP 6) were selected with analog electrical stimulation, and in blank group no any therapy was applied. The changes of drug craving were evaluated by Visual Analogue Scale (VAS) and the changes of beta-EP and Dyn-A in plasma before and after treatment were tested by radioimmunoassay.

RESULTSThe relapse rate of 77.3% (17/22) in acupuncture group 1 was lower than those of 88.5% (23/26) in acupuncture group 2, 90.5% (19/21) in simulation group and 95.7% (22/23) in blank group (all P < 0.05). At the 8th and 10th week of treatment, the VAS scores in acupuncture group 1 and 2 were much lower than those in blank group and simulation group (all P < 0.01); in which, it was lower in acupuncture group 1 than that in acupuncture group 2 (P < 0.05), and lower in simulation group than that in blank group. After 10 weeks of treatment, compared with the status before treatment, beta-EP and Dyn-A in plasma were increased in acupuncture group 1 and 2 (P < 0.05, P < 0.01), Dyn-A was decreased in both simulation and blank groups (both P < 0. 01) which was less obvious than those in both acupuncture groups (both P < 0.01) and superior in acupuncture group 1 than that in group 2 (P < 0.05).

CONCLUSIONElectroacupuncture at Jiaji (EX-B 2) can suppress the drug craving and reduce the relapse rate, and the mechanism may be related with the content of beta-EP, especially the increase of Dyn-A in plasma.

OBJECTIVETo explore young hypertensive people's vascular endothelial dysfunction and the early atherosclerosis changes.

METHODSRural youth subjects aged 20 to 35 in 6 villages were randomly selected from 20 villages of 3 townships, including Qili, Laojun and Shayan, in Hanzhong, Shanxi, China, from March to April of 2005, to survey their blood pressure and other related factors. 97 subjects with high blood pressure (hypertensive group) were detected while 400 with normal blood pressure (normal group). We measured their brachial artery flow-mediated vascular endothelial-dependent diastolic function (FMD) and the carotid intima-media thickness (IMT) by high resolution vascular ultrasound method, and other biochemical indexes.

RESULTSThe body mass index (BMI) ((24.7 ± 4.3) kg/m²), waistline ((84.1 ± 11.7) cm), hipline ((92.5 ± 7.4) cm), TC ((4.6 ± 0.8) mmol/L), LDL-C ((2.8 ± 0.5) mmol/L), TG ((1.7 ± 1.1) mmol/L) and the blood insulin (INS) ((8.6 ± 4.4) mIu/L) were all significantly increased in young hypertensive group than those in normotensive group (respectively were (22.1 ± 3.0) kg/m(2), (76.7 ± 8.9) cm, (88.9 ± 5.6) cm, (4.3 ± 0.7) mmol/L, (2.6 ± 0.4) mmol/L, (1.4 ± 0.8) mmol/L and (6.9 ± 2.1) mIu/L) (P < 0.05). The FMD of the brachial artery in hypertensive group was markedly lower than normal group ((0.103 ± 0.04)% and (0.117 ± 0.05)%, P < 0.05). The IMT of two groups were (0.49 ± 0.07) mm and (0.48 ± 0.07) mm, but there was no statistically significant differences (P > 0.05).

CONCLUSIONYoung hypertensive people with a few cardiovascular risk factors earlier appear dysfunction of the flow-mediated vascular endothelial-dependent dilation, which is prior to the increase in carotid IMT.

Traditional Chinese Medicine massage is a kind of physiotherapy which affects on specific parts of the body surface by means of training to regulate the function of the body to achieve the therapeutic effect. In this work,under positive detection model, the chemical fingerprint of exhaled breath from volunteers before and after receiving Traditional Chinese Medicine massage within m/z 50-1000 were detected by extractive electrospray ionization-mass spectrometry (EESI-MS). And through high resolution mass spectrometry analysis, the metabolites such as epinephrine (m/z 184. 0889), 3-(3-hydroxyphenyl) propionic acid (m/z 167.0615) and L-tryptophan (m/z 205. 0933) were successfully identified. Besides, chemical fingerprints of volunteers before and after receiving Traditional Chinese Medicine massage under different health condition were clearly differentiated via partial least squares discrimination analysis (PLS-DA). The results showed that Traditional Chinese Medicine massage could significantly change the metabolic process of volunteers. Moreover, it further indicated that the established method could provide a real time fashion to follow metabolic changes caused by Traditional Chinese Medicine massage.

OBJECTIVE: To study the relationship between the DNA content in follicular epithelial cells of the human thyroid and postmortem interval (PMI). METHODS: Changes of the DNA content in thyroid follicular epithelial cells at different PMI were determined by Methyl Green-Pyronin (MGP) stain combined with an image analysis technique. RESULTS: The average DNA content in the thyroid follicular epithelial continued to decrease with increased PMI. The coefficient of determination for DNA content with average gray, aimed area, aimed area ratio and positive index in follicular epithelial cells were 0.960, 0.987, 0.988 and 0.990, respectively. CONCLUSION There is an apparent correlation between the average DNA content of follicular epithelial cells and the PMI. MGP stain combined with an image analysis technique seems to be a useful means to study the degradation of DNA in thyroid follicular epithelial cells.

OBJECTIVETo investigate a method for quantitative differential diagnosis of damp-heat and cold-damp impeding syndrome of rheumatoid arthritis (RA) in Chinese medicine (CM).

METHODSLaboratory parameters were collected from 306 patients with RA. The clinical symptoms and laboratory parameters were compared between patients with these two syndromes (158 with RA of damp-heat impeding syndrome, and 148 with RA of cold-damp impeding syndrome), and a regression equation was established to facilitate discrimination of the two RA syndromes.

RESULTSThere were significant differences in disease activity score in 28 joints [DAS28 (4)], erythrocyte sedimentation rate (ESR), white blood cell count (WBC), C-reactive protein (CRP), platelet count (PLT), albumin (ALB) and globulin (GLB) between the two syndrome of RA (P<0.05). Logistic regression analysis showed that the parameters ESR, WBC, CRP, joint pyrexia, joint cold, thirst, sweating, aversion to wind and cold, and cold extremities were statistically useful to discriminate damp-heat from cold-damp impeding syndrome. The regression equation was as follows: P=1/{1+exp[-(3.0-0.021X (1)-0.196X (2)-0.163X (3)-1.559X (4)+1.504X (5)-0.927X (6)-1.039X (7)+1.070X (8)+1.330X (9))]}. The independent variables X (1)-X (9) were ESR, WBC, CRP, hot joint, cold joint, thirst, sweating, aversion to wind and cold, and cold limbs. A P value > 0.5 signified cold-damp impeding syndrome, and a P value < 0.5 signified damp-heat impeding syndrome. The accuracy was 90.2%.

CONCLUSIONThe regression equation may be useful for discriminating damp-heat from cold-damp impeding syndrome of RA.
