Type 1 diabetes mellitus and autoimmune thyroid disorders are the most common combination of autoimmune polyendocrine syndrome type Ⅲ(APS Ⅲ). However, APS Ⅲ combined with myasthenia gravis is rare. We described a male patient with myasthenia gravis, type 1 diabetes mellitus, and Hashimoto thyroiditis, who was diagnosed as APS Ⅲ. The human leukocyte antigen (HLA)type was analyzed in this patient. We subsequently reviewed 11 cases of APS Ⅲ combined with myasthenia gravis. This review revealed that HLA-DR9/DQ9 might be a specific HLA subtype associated with APS Ⅲ and complicated with myasthenia gravis .

Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

OBJECTIVE: To assess the effects of intracoronary diltiazem on no-reflow phenomenon of infarct-related artery (IRA) after emergent percutaneous transluminal coronary angioplasty or/and intracoronary stenting (PTCA/Stenting) in the patients with acute myocardial infarction (AMI). METHODS: We studied 34 AMI patients with no-reflow phenomenon of IRA after emergent PTCA/Stenting between January 1999 and August 2005. Urokinase-treated group (n=16) was given intracoronary urokinase 30,0000 - 50,0000 units within 15 - 30 minutes between January 1999 and April 2002 while diltiazem-treated group (n=18) was given intracoronary diltiazem 0.5 - 2 mg within 10 - 30 minutes between May 2002 and August 2005. Fifteen minutes later, coronary arteriography (CAG) was performed and the thrombolysis in myocardial infarction (TIMI) flow grade was measured. RESULTS: No apparent change of TIMI flow grade was found between pre-administration and post-administration of intracoronary urokinase, but TIMI flow grade was significantly improved after intracoronary diltiazem (P<0.01). TIMI flow grade of diltiazem-treated group was significantly higher than that of urokinase-treated group after the administration (P<0.05). The percentage of the patients who reached TIMI flow grade 3 after the intracoronary administration was higher in the diltiazem-treated group than that in the urokinase-treated group (P<0.01). CONCLUSION The intracoronary administration of diltiazem 0.5~2mg can effectively improve the no-reflow phenomenon after emergent PTCA/Stenting in patients with AMI.

OBJECTIVE: To evaluate the short and mid-term changes of the cardiac morphology after percutaneous transcatheter closure of ventricular septal defects (VSD) with transthoracic echocardiography (TTE). METHODS: The left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic volume (LVEDV), left atrial diameter (LAd), and right ventricular diameter (RVd) in 30 VSD patients were measured before the VSD closure,and on the 3rd day, 3rd month, and 6th month after the VSD closure by TTE. RESULTS: LVEDD and LVEDV significantly decreased on the 3rd day after the VSD closure compared with pre-VSD closure. LVEDD and LVEDV continuously decreased on the 3rd month and 6th month after the VSD closure. LAd was smaller on the 3rd month and 6th month after the VSD closure, but there was not significant difference between the 3rd and 6th month. RVd increased on the 3rd day after the VSD closure, while no significant difference was found among the 3rd month and 6th month before and after VSD closure. CONCLUSION Percutaneous transcatheter VSD closure may effectively improve the cardiac remodeling in VSD patients in the short and mid-term follow-up.

Objective To study the relationship between ischemic stroke (IS) and both gene polymorphisms of methylenetetrahydrofolate reductase (MTHFR) and cigarette smoking. Methods Four hundred and fifty-four patients with IS and 334 controls were recruited in our study; their gene polymorphisms of MTHFR were detected by PCR and denaturing high performance liquid chromatogram (DHPLC). The patients were further divided into different subgroups based on TOAST criteria and scores of neurological impairments and the distribution of MTHFR genotypes were analyzed accordingly. The relationships between IS and both cigarette smoking and these genotypes were measured by odds ratios (ORs) and 95％ confidence intervals (95％CIs). The ORs and 95％ Cls were calculated by unconditional logistic regression. Results TT genotype and T allele were associated with LAA type and CE type,moderate type and severe type of IS. OR of TT genotype and T allele in smoking patients with IS were 4.393 and 2.359, respectively; but the OR ofCC genotype in smoking patients with IS was 0.353. On the other hand, the OR of all genotypes and alleles in non-smoking patients with IS were not significantly different as compared with those in controls. Conclusion Cigarette smokers with T alleles are likely to suffer IS, but those cigarette smokers with C alleles are not; and there exist interactions between cigarette smoking and MTHFR gene in the pathogenesis of IS.

OBJECTIVETo investigate the basis of distinctive function of acupoint through observing the effects of acupuncture at the areas of acupoint and non-acupoint on functional connectivity of different brain regions.

METHODSTwenty-one healthy volunteers were randomly divided into two groups: 12 cases in the acupoint group and 9 cases in the non-acupoints group. Bilateral Zusanli (ST 36) and its lateral 3-4 mm were punctured with twirling manipulation in the acupoint group and the non-acupoints group respectively. Before and after 25 minutes treatment, data of functional magnetic resonance imaging (fMRI) scanning was taken from bilateral cingulate gyrus (seed point) to analyze the functional connectivity in both groups.

RESULTSBrain functional connectivity was demonstrated widely in both acupoint group and non-acupoint group after acupuncture. Comparing with the non-acupoint group, in the acupoint group, brain functional connectivity with posterior cingulate gyrus was found more intensively in the bilateral tonsil, right dentate nucleus, bilateral uvula, left declive and right tuber of cerebellum, as well as in the left inferior frontal gyrus, right middle temporal gyurs, bilateral paracentral lobule, left cingulate cortex, right superior temporal gyrus, right anterior cingulate gyrus etc., however, its connectivity was less in the bilateral medial frontal gyrus and right inferior frontal gyrus.

CONCLUSIONBoth acupoint and non-acupoint can evoke brain functional connectivity that is similar on the most of regions, but the intensity of this connectivity in the acupoint group is higher than that in the non-acupoint group.

OBJECTIVEVariations of the signal intensities in the magnetic resonance (MR) T(1)-weighted image (T(1)WI) of globus pallidus among manganese(Mn)-exposed workers were explored to provide a scientific basis for exposed biomarker of manganese-injured central nervous system (CNS).

METHODSThe brain MR T(1) and T(2) WI in eighteen male asymptomatic Mn-exposed, eight manganism and nine healthy control workers were examined routinely by adopting a 1.5 Tesla signal superconducting system. The SIGP and the signal intensity in frontal white matter (SIFWM) in the same side were determined, then pallidal index (PI) was calculated. Concentration of MnO(2) in workplaces and content of manganese in red blood cell (MnRBC) among workers were respectively determined by flame atomic absorption spectrometer (AAS) and inductively coupled plasma-atomic emission spectrophotometry (ICP-AES). The follow-up investigation in the eight high Mn-exposed workers was made one year later.

RESULTSThe results showed that the median of air MnO(2) in smelting workplace was 0.64 mg/m(3)(0.07 - 5.40 mg/m(3)), which were respective 0.56 mg/m(3)(0.09 - 1.71 mg/m(3)) in power distribution room (low Mn-exposure) and 0.89 mg/m(3) (0.07 - 5.40 mg/m(3)) in furnace (high Mn-exposure). PI in the Mn-exposed and high Mn-exposed workers were both higher than those of the manganism and control workers(116.4 +/- 8.2, 119.0 +/- 7.9, 105.3 +/- 8.4 and 102.2 +/- 1.5, respectively. Mn vs control, t' = 7.146, P = 0.000; Mn vs manganism, t = 3.181, P = 0.004. High Mn-exposure vs control, t' = 7.446, P = 0.000; high Mn-exposure vs manganism, t = 3.763, P = 0.001). The increased signal in T(1)WI of globus pallidus was observed in Mn-exposed workers, especially in high Mn-exposed workers. The content of manganese in red blood cell of Mn-exposed and control workers was significantly higher than those of the manganism workers [(151.6 +/- 40.5) ng/ml, (149.2 +/- 21.3) ng/ml, (154.5 +/- 46.6) ng/ml, (144.4 +/- 14.2) ng/ml, (20.8 +/- 7.4) ng/ml respectively. The difference was significant in statistics. Manganism vs control, t = 20.206, P = 0.000; manganism vs Mn, t' = 13.144, P = 0.000; manganism vs low and high Mn, t' = 12.964, 9.957, respectively, P = 0.000]. Only a decreased median of air MnO(2) in furnace was found one year later (0.89, 0.31 mg/m(3), Z = -2.142, P = 0.032). The difference was significant in statistics.

CONCLUSIONOur data suggests that SIGP of MR T(1)WI among workers was obviously increased by manganese-exposure. PI may be taken as the signal of CNS injury which was induced by manganese-exposure.
