Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.

and indexes of the ROI which had significant difference between the groups. Results In the white matter regions, MD, D∥and D⊥in many regions of AD group were increased significantly than the control group, and the differences were statistically significant. MD and D ⊥ showed more abnormalities, including the SCC, PCB, and FWM. Meanwhile, MK, K∥and K⊥in many regions of AD were decreased, and the differences were statistically significant. K ⊥ showed more abnormalities, including the SCC, FWM and TWM. In the gray matter regions, MD, D∥and D⊥of hippocampal of the AD group were all increased than the control group. However, it showed that MK and K⊥of the thalamus in AD group were 0.99 ± 0.10, 1.00 ± 0.11, respectively, and both increased than the control group (the value of MK and K⊥were 0.90±0.06, 0.90±0.07, respectively), and the differences were statistically significant (t values was 3.31, 3.57 respectively, and both P values were<0.01). The indexes of different ROI had correlations with the MMSE scores. There were more regions in kurtosis indexes correlated with the MMSE scores than the diffusion indexes. The strongest correlation among the analyses was MK of the SCC (r=0.73, P<0.05). Conclusions This study based on DKI found the complex alterations aroused by microstructural changes were not only in the white matter but also the gray matter of the AD patients, especially the increased kurtosis of the thalamus, and this suggested that the microstructural complexity of it was increased. Moreover, it also suggested that indexes of DKI had varied sensitivity in detecting different diffusion alterations.

Objective To observe the expressions of bone morphogenetic protein-2(BMP-2)and bone morphogenetie protein-7(BMP-7)in the synovial tissue of fluorosis rats and its correlation with pathogenic mechanism of fluorosis arthritis.Methods Thirty-two SD rats were randomly divided into 4 groups:the control group,low,moderate and high-dose fluoride group.The control group ate commou fodder.The low,moderate and high dose fluoride group were fed with fodder composed of 25%.35%and 68%of corn(containing fluorine of 148.00 mg/kg)in chronic endemic fluorosis region in Guizhou Province.After 140 days,the expressions of BMP-2 and BMP-7 protein were determined by immunohistochemistry and assayed the absorbanee by computer image-pattern analysis system.Light microscope was used to observe the synovial tissue by Hematoxin Eosin,and calculated the pathological integral of synovium according to pathological grade standard.Results The expressions of BMP-2 (32.50±2.73)and BMP-7(38.90±2.56)in the control group was spare.Compared with the control group,the expressions of BMP-2(59.43±5.12,79.82±6.41,101.76±7.56)and BMP-7(55.10±4.82,78.42±5.61,98.46± 6.05)in the synovial tissue was up-regulated in each experimental groups(P＜0.05),especially in the moderate dose and the high-dose groups(P＜0.05).Compared with the control group(0.54±0.21).the pathological integral of synovium increased(P＜0.05)in each experimental groups(1.04±0.98,4.69±1.28,8.60±2.07).The expressions of BMP-2 and BMP-7 in the synovial tissue was found to be positively related with the pathological integral of synovium(r=0.98,0.99,P＜0.05).Conclusion The BMP-2 and BMP-7 play an important role in the development of fluorosis arthritis,probably by affecting osteogenesis.

Objective To observe the cost-effectiveness of using continuous subcutaneous insulin infusion (CS Ⅱ) and multi-point daily insulin injections (MDI) in controlling blood sugar in the newly hospitalized type 2 diabetes patients. Methods Retrospective analysis on 86 cases taking CS Ⅱ and 103 cases using MDI on a 'blood sugar control program' among the newly hospitalized patients with type 2 diabetes. The period for observation was 2 weeks, using cost-effectiveness analysis methods to evaluate the two treatment programs. Results After two weeks of treatment, the effectiveness in the control of blood sugar in CS Ⅱ group was similar to the MDI group, with no significant difference(P<0.05) and the adverse reactions were similar. Costs in the CS Ⅱ program (Yuan/person) was less than in the MDI program (1478.34 vs. 1620.46), with significant differences (P< 0.05). The cost-effectiveness ratios (C/E) were 15.07 in the CS Ⅱ group, and 16.34 in the MDI group, with no significant difference (P>0.05). In order to further reduce the cost of CS Ⅱ group as a reference, the incremental cost-effectiveness ratio (△C/ △E)ofthe MDI group was 129.20. Conclusion Costs-effective of the CS Ⅱ program was better than the MDI one in treating the newly hospitalized patients with type 2 diabetes, suggesting that CS Ⅱ program might be a better choice for hospitals to carry on an intensive insulin therapy program.

A total of 126 patients with type 2 diabetes mellitus were randomized into two groups:one received glimepiride 1 mg twice daily and the other 2 mg once daily.Fasing blood glucose(BG),BG 2 h after meals(breakfast,lunch and dinner)and HbA_(IC)were tested,△and standard deviation of the 4 point BG were calculated.It was found that two kinds of administration of glimepiride were equally effective in decreasing BG and once daily aministration could ease better the fluctuation of BG.
