Study on the relationship between Chinese medicine constitutive susceptibility and diversity of syndrome in diabetic nephropathy / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the relationship between Chinese medicine (CM) constitutive susceptibility and syndrome diversity in diabetic nephropathy (DN).</p><p><b>METHODS</b>Epidemiologic investigation on constitution adopting the "Constitution in Chinese Medicine Questionnaire" (CCMQ), and survey on syndrome type by CM syndrome scale (preliminary) were carried out in 180 DN patients. Cluster analysis on symptom items was used to determine the syndrome type, and canonical correlation analysis was used to analyze the relationship between patients' constitution and syndrome.</p><p><b>RESULTS</b>Baseline levels in all enrolled patients were not different statistically. Cluster analysis showed 8 syndromes existed in DN patients, namely: I, qi-yin deficiency with qi-stagnancy type; II, yin-yang deficiency with heat-water-blood stasis type; III, qi-yin deficiency with dampness-heat type; IV, yin-yang deficiency with blood-stasis and heat type; V, qi-yin deficiency with stagnant heat type; VI, yin-yang deficiency with inner dampness-heat stagnancy type; VII, yin deficiency with heat stagnancy type; and VIII, Kidney (Shen)-Spleen (Pi) deficiency with stagnant heat type. Correlation analysis on the 8 syndromes and the 9 constitutions showed statistical significant correlations between syndrome III and dampness-heat constitution (P=0.0001); syndrome IV and blood-stasis constitution (P=0.0001); and syndrome VII and yin-deficiency constitution (P=0.0180).</p><p><b>CONCLUSION</b>Certain relationship revealed between CM constitutions and syndrome types; constitution decides the disease genesis, its syndrome type and prognosis, as well as the change of syndromes.</p>

CT and MRI in diagnosis of avascular necrosis of the vertebral body / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the value of CT and MRI in the diagnosis of avascular necrosis of the vertebral body (ANV).</p><p><b>METHODS</b>Twelve ANV patients were retrospectively analysed by their medical history, clinic manifestation, CT and MRI. Twelve AVN patients were treated with percutaneous vertebroplasty (PVP). The pain level of each patient was assessed, both before and after the procedure, using a visual analogue scale (VAS).</p><p><b>RESULTS</b>All the patients had ANV in the thoracolumbar spine. The intravertebral vaccum phenomenon (VP), with gas or fluid-like collection, was seen on computed tomographic (CT) images and magnetic resonance images (MRI). In the early stages, the VP zone was characterized by fluid-like collection, and was low intensity on T1, high intensity on T2. In the latter stages, the margin of VP zone had sclerotic change on CT scan. VAS score decreased from preoperative (9.08 +/- 0.76) to (2.33 +/- 1.43) at 3 days after PVP.</p><p><b>CONCLUSION</b>ANV must be considered as a possible diagnosis of VP secondary to osteoporotic vertebral fractures. Both CT and MRI could provide reliable diagnostic proof for ANV. PVP is proved to be an effective and safe procedure for the treatment of ANV, and could provid quick pain relief.</p>

Association of Chinese medicine constitution susceptibility to diabetic nephropathy and transforming growth factor-β1 (T869C) gene polymorphism / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the association of Chinese medicine constitution susceptibility to diabetic nephropathy (DN) and transforming growth factor (TGF)-β1 (T869C) gene polymorphism.</p><p><b>METHODS</b>TGF-β1 gene polymorphism detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was screened for 180 DN cases and 180 type 2 diabetic mellitus (T2DM) cases without combined DN. Patients with DN were surveyed epidemiologically with constitution in the Chinese medicine questionnaire (CCMQ). Binary logistic regression analysis was utilized to study the correlation between nine types of Chinese medicine constitution and TGF-β1 (T869C) gene polymorphisms.</p><p><b>RESULTS</b>The DN group has a higher frequency of TGF-β1 (T869C) gene polymorphism than the T2DM group, and CC/CT genotypes than the T2DM group [CC, CT, TT (DN group): 88, 87, 5 (cases) versus (T2DM group) 71, 73, 36 (cases), P<0.05]. The phlegm-dampness constitution, damp-heat constitution, and blood stasis constitution have correlations with TGF-β1 (T869C) gene polymorphism.</p><p><b>CONCLUSION</b>Chinese medicine constitutions were associated with TGF-β1 (T869C) gene polymorphism, a potential predictor of susceptibility to DN in T2DM patients.</p>

Relationship of Peripheral Vascular Disease with Gender and the Levels of Uric Acid in Patients with Type 2 Diabetes / 中国慢性病预防与控制

Objective To study the relationship of peripheral vascular disease(PVD) with gender and serum uric acid in patients with type 2 diabetes.Methods Lower extremities of 82 male and 70 female patients with type 2 diabetes were screened for PVD by color Doppler uhrasonography,and the levels of serum uric acid,fasting blood glucose,glycosylated hemoglobin and serum lipid were examined.Results In male,serum uric acid(328.12?107.30) ?mol/L,age(65.00?9.66) yrs,durations of diabetes(7.38?6.17) yrs, HBA_1Cc(7.74?1.83)% were significantly higher in the diabetic patients with PVD than those in patients without PVD.And these changes were not shown in female patients.In male,the detectable rate of PVD(82.14%)in diabetics with high level uric acid was also increased than that in normal uric acid group(53.70%).Conclusion The higher level of serum uric acid in type 2 diabetics was closely related with the occurrence of peripheral vascular disease in male.So we should actively control the level of serum uric acid in male.
