OBJECTIVETo compare the clinical effective differences between pricking blood combined with moxibustion and west medication for acute gouty arthritis.

METHODSForty patients with acute gouty arthritis were randomly divided into a pricking blood combined with moxibustion group (a combination group) and a western medication group, 20 cases in each one. In the combination group, pricking blood was used at the most painful points of the red turgid and painful joint once three days, total 3 times; moxibustion was applied at the same joint for 15-20 min, once a day. The moxibustion was adopted for 10 days. In the western medication group, 0. 3 g ibuprofen was prescribed orally twice a day for 10 days. The changes of uric acid (UA), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) and the joint syndrome and symptom score before and after: treatment were observed. Results In the two groups, the UA, the hs-CRP, the ESR and the joint syndrome and symptom scores were lower than those before treatment (all P<0. 05). After treatment, the UA, the ESR and the joint syndrome and symptom scores in the combination group were declined more apparently than those in the western medication group (all P<0. 05). The total effective rate in the combination group was 85. 0% (17/20) which was better than 75. 0% (15/20) in the western medication group (P<0. 05).

CONCLUSIONPricking blood combined with moxibustion could improve the joint symptoms more effectively and the effect is better than ibuprofen orally.

OBJECTIVETo explore the clinical efficacy of moxibustion on rheumatoid arthritis (RA) in the patients and the impacts on the inflammatory indices.

METHODSForty RA patients were randomized into an observation group and a control group, 20 cases in each one. In the control group, diclofenac sodium sustained release tablets were used, 0.3 g each time, twice a day; methotrexate tablets were used, 10 mg each time, once a week; folic acid was used, 5 mg each time, once a week. In the observation group, on the basis of the treatment as the control group, moxibustion was added specially on the swelling and painful joints, once a day, 15-20 min each time till: the local skin turned slightly red. The treatment was given once a day, at the interval of 1 day after every 6 treatments. In the two groups, the efficacy was observed after 30-day treatment. Before and after treatment, the rheumatoid factor (RF), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), disease activity score-28 (DAS-28) and the score of joint symptom and physical signs were observed.

RESULTSCompared with those before treatment, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score were all reduced in the RA patients of the two groups after treatment (all P < 0.05). Compared with the control group, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score in the observation group were improved much apparently (all P < 0.05). The total effective rate was 85.0% (17/20) in the observation group and was 80.0% (16/20) in the control group. The total effective rate in the observation group was apparently better than that in the control group (P < 0.05).

CONCLUSIONMoxibustion as supplement relieves the joint symptoms, reduces the inflammatory reactive indices and improves the clinical efficacy in the RA patients.

Objective To evaluate biochemical characteristics and the trend of diabetic complications in patients with newly-diagnosed type 2 diabetes from 1994 to 2008. Methods We utilized the database of the diabetes complications assessment and analyzed the metabolic disorder and the diabetic complications in the patients with newly diagnosed diabetes. Results 2 085 cases were collected, including 1189 males and 896 females. The average age of onset of diabetes was 51.6±13.1 and 54.6±7.9 yrs respectively in 2008 and 1994. During 1994,no case was found in subjects aged 20-29 yrs and 5% of the patients were aged 30-39; but 2% of patients aged 20-29 and 16% aged 30-39 yrs were found in 2008. BMI was increased from 24.48±4.15 in 1994 to 26.03±3.63 in 2008. Percentage of patients with abnormal BMI ( ≥25 kg/m2 ), WHR [≥0.90 (male) or ≥0.85 (female)]increased significantly from 63.6%, 75.0%, and 71.4% in 1994 to 79.6%, 95.2%, and 93.8% in 2008,respectively. Both SBP and DBP were not significantly changed. The fasting blood and postprandial blood glucose,HbA1c decreased from 10.3 mmol/L, 15.2 mmol/L, 11.1% in 1994 to 9.0 mmol/L, 14.3 mmol/L, and 8.6% in 2008, respectively. The average TG level increased from 1.7 mmol/L in 1994 to 2. 1 mmol/L in 2008,however, TC and HDL level were not significantly changed. The prevalence of diabetic retinopathy decreased from 28.2% in 1994 to 3.9% in 2008. The prevalence of diabetic nephropathy increased from 17.7% in 1994 to 24.6% in 2008. The prevalence of diabetic cardiovascular disease increased from 14.3% in 1994 to 24. 1% in 2008. Compared with the patients without microvascular complications, the patients with microvascular complications had higher SBP, DBP, and HbA1c( 136/78 vs 130/77 mm Hg, 9.41% vs 9.11% ). The patients with macrovascular complications had older age, higher SBP, TC, and TG than those without macrovascular complications (53.4 vs 50.0 yrs; 132 vs 129 mm Hg ; 5.3 vs 5.1 mmol/L and 2.6 vs 2.1 mmol/L). Conclusions In the studied newly-diagnosed diabetic patients from 1994 to 2008, there were increasing incidences of obesity and hypertriglyceridemia. However, the prevalence of diabetic retinopathy decreased significantly, while that of nephropathy showed no significant change.Cardiovascular complications were markedly increased.

Objective To quantitatively analyze brucellar spondylitis, tuberculous spondylitis and spinal metastatic tumors by dynamic contrast-enhanced (DCE)-MRI, and to evaluate the quantitative DCE-MRI in the differential diagnosis of brucellar spondylitis, tuberculous spondylitis and spinal metastatic tumors. Methods This was a retrospective study including 30 patients with brucellar spondylitis, 30 with tuberculous spondylitis, and 30 with spinal metastatic tumors. The clinical and demographic data were collected. All patients received routine MRI and DCE-MRI examinations. Volume transfer constant(Ktrans), rate constant(Kep), extravascular extracellular volume fraction(Ve) and plasma volume fraction(Vp) of diseased vertebral bodies of the patients with brucellar spondylitis, tuberculous spondylitis and spinal metastatic tumors were measured on perfusion parameter maps. All indexes showed non-normal distribution. Differences of all indexes were compared and analyzed statistically with rank-sum test among the above diseases. Results For brucellosis spondylitis, spinal tuberculosis, and vertebrae metastasis, the values of Ktrans were(0.716 ± 0.017),(0.316 ± 0.004),(0.986 ± 0.012)min-1, the values of Kep were(1.326 ± 0.018), (0.747 ± 0.005),(2.899 ± 0.054)min-1, the values of Ve were 0.541 ± 0.011, 0.427 ± 0.017, 0.338 ± 0.007 and the values of Vp were 0.034 ± 0.003, 0.029 ± 0.003, 0.049 ± 0.007. The differences suggested statistical significance(H=50.24, 52.49, 48.31, 46.54, P<0.01) among the three diseases. Conclusion DCE-MRI quantitative analysis is helpful in the differential diagnosis of brucellar spondylitis, tuberculous spondylitis and spinal metastatic tumors.
