Objective To study kidney transplantation in the aged and its perioperative management. Methods Scrutinized screening of heart,lung and liver were carried out before renal transplantation for 29 patients,aged 65～84.Color Doppler B type ultrasonic inspection was used to determine the status of arteriae iliaca externa and arteriae iliaca interna.Tissue match included HLA and PRA measurement.Warm ischemia time of donor kidney was within 5 minutes and cold ischemia time 10 hours.The dose of MP was under 2.0 g during the period of operation and the immunosuppressive regimen was CsA or FK506+MMF+Pred.The general condition,blood electrolytes,whole blood CsA or FK506 concentration and immune index were monitored. Results There were 4 cases of AR,1 cases of FK506 toxicity and 1 case of lung infection.All these 6 patients were cured.1 kidney graft was removed because of thrombogenesis of renal artery.Up to now,the other 28 have been surviving with the graft functioning well for 1 to 5 years. Conclusions Abide to the indications of kidney transplantation,donor kidney of good quality and well tissue match were important in the elderly patients.With comprehensive monitoring and adequate management,kidney transplant in old patients can achieve sa tisfying outcome.Rational application of immunosuppressants and effective long term follow up are major factors for long term allograft survival.

Objective To establish the method of gene mutation screening for HME and investigate the relationship between genotype and clinical phenotype in HME patients. Methods Fifteen cases of HME probands were divided into the following four subgroups: mild (M) and severe ( Ⅰ S, Ⅱ S, Ⅲ S) according to the clinical diagnosis. DNA samples were obtained from the probands and family members. All of the EXT1 and EXT2 gene exons and their boundary sequences were amplified by PCR, and sequenced by directsequencing. Then the relationship between the genotypes and clinical phenotype was analyzed. Results Among the fifteen cases of HME probands, nine harbored EXT1 gene mutation, while the other 6 were positive for EXT2 gene mutation. Moreover, six novel mutations in EXT1 gene, including I8 + 2T ＞ G, c. 1182delG,c. 1108G ＞T(p. E370X) ,c. 335delA,c. 361C ＞T(p. Q121X) and c. 1879_1881delCAC were identified. In 9 patients with EXT1 gene mutation, 2 (22. 2% ) were M-type, 2 (22. 2% ) were Ⅰ S -type, 4 (44. 4% )were Ⅱ S-type,and 1 ( 11.1% ) was ⅢS-type. Whereas, 5 cases (83.3%) were M-type and only one case was Ⅱ S-type( 16. 7% ) in 6 patients with EXT2 gene mutation. Conclusions An accurate and simple gene diagnostic method for HME was established. Six novel EXT1 gene mutations, including I8 + 2T ＞ G,c. 1182delG, c. 1108G ＞T(p. E370X), c. 335delA, c. 361C ＞T(p. Q121X)and c. 1879_1881delCAC were identified as well. The clinical phenotype of the patients with EXT1 gene mutation was more severe compared to those with EXT2 gene mutations.

OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).

METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.

RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).

CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.

METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.

RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).

CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

Objective To establish a method of gene mutation detection for congenital adrenal hyperplasia (CAH) by using sequencing, single nucleotide polymorphisms (SNP) analysis and T-A cloning. Methods The blood samples of 33 patients with 21-hydroxylase deficiency (21-OHD) , 2 patients with 17α-hydroxylase deficiency (17-OHD) , the parents of all the patients and 105 healthy children were collected. Genomic DNA were extracted form the blood samples. To detect the gene mutation of CYP21A2,highly specific primers for CYP21A2 gene were designed according to the sequence differences between CYP21A2 gene and its pseudogene. The whole CYP21A2 gene was amplified and sequenced. SNP analysis and TA cloning of PCR products were also carried out. The molecular diagnosis of 17-OHD was based on the amplification and sequencing of CYP17A1 gene. Results The corresponding gene mutations was determined in all the patients based on the method established in this study. Thirteen mutations of CYP21A2 gene were identified in 33 patients with 21-OHD. The 3 most frequent mutation of CYP21A2 gene were IVS2-13A/C >G, p. I172N and chimeric mutation, which accounted for 32% (21/66) ,27% (18/66) and 15% (10/66) respectively. Ninety-one persent mutations of CYP21A2 gene resulted from pseudogene conversion. In 2 patients with 17-OHD, homozygous mutations of CYP17A1 gene, IVS4-6A > G and p. 487_489del were identified separately. All the gene mutations detected in the patients were inherited from their parents. No mutation of CYP21A2 gene or CYP17A1 gene was found in the healthy children. Conclusion A method of gene mutation detection for CAH has been established. It will be beneficial to clinical diagnosis of CAH.

OBJECTIVETo study the effect of electro-acupuncture (EA) at Neiguan (PC6) and Lieque (LU7) on the expression of protein kinases in cardiomyocytes of myocardial ischemia (MI) rats.

METHODSHealthy male SD rats were randomly divided into the control group, the model group, the Neiguan point group, the Lieque point group, and the non-meridian non-acupoint group, 10 in each group by random digit table. The MI rat model was established by injecting isoprenaline hydrochloride (85 mg/kg). EA at Neiguan (PC6), Lieque (LU7), and non-meridian non-acupoint were respectively performed. Changes of the expression of protein kinases [such as protein kinase A (PKA), protein kinase C (PKC), protein kinase G (PKG)] in rat cardiomyocytes were observed using Western blot.

RESULTSCompared with the control group, expression levels of PKA, PKC, and PKG increased obviously in the model group (P < 0.01). Compared with the model group, expression levels of PKA, PKC, and PKG decreased in the Neiguan point group and the Lieque point group (P < 0.01, P < 0.05). Expression levels of PKA decreased in the non-meridian non-acupoint group (P < 0.01). Compared with the Neiguan point group, expression levels of PKA, PKC, and PKG increased in the non-meridian non-acupoint group and the Lieque point group (P < 0.01, P < 0.05). Compared with the Lieque point group, expression levels of PKA, PKC, and PKG increased in the non-meridian non-acupoint group (P < 0.01, P < 0.05).

CONCLUSIONEA at Neiguan (PC6) and Lieque (LU7) could decrease protein expression levels of PKA, PKC and PKG in rat myocardial cells, and the effect of acupuncture at Neiguan (PC6) was better than that obtained by EA at Lieque (LU7).

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.
