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.

Object: To investigate the effects of Huaiqihuang Granule, a compound Chinese herbal medicine, on expressions of nephrin and podocin of slit diaphragm of glomerular podocytes in rats with adriamycin-induced nephrosis and to explore the mechanism in reducing the proteinuria. Methods: Twenty SD rats were randomly divided into five groups: control group, model group, glucocorticoid group, Huaiqihuang Granule group and Huaiqihuang Granule plus glucocorticoid group. The 24-hour urine was collected 7, 14, 21 and 28 days after adriamycin injection respectively to measure 24-hour urinary protein, and all rats were sacrificed after 28-day treatment. Pathological changes in renal tissues were observed under a light microscope and an electron microscope. Expressions of nephrin and podocin mRNAs in renal cortex were determined by real-time polymerase chain reaction, and protein levels of nephrin and podocin were detected by Western blotting. Results: (1) In the model group and the treatment groups, the level of urinary protein increased significantly from the 14th day. (2) Under the light microscope, inflammatory cells and slight fibroplasia were found in renal interstitium of the model group, but there were less inflammatory cells in renal interstitium in the intervention groups than in the model group. Under the electron microscope, 29 days after adriamycin injection, extensive fusion of foot processes was observed. (3) The expressions of nephrin and podocin were higher in treatment groups than in the model group. (4) Proteinuria level was negatively correlated with the expressions of nephrin mRNA and nephrin and podocin proteins. Conclusion: The above results indicate that Huaiqihuang Granule can maintain the integrity of the slid diaphragram in podocyte, alleviate the lesion of glomerular filtration membrane, and decrease the proteinuria by up-regulating the expressions of nephrin and podocin. Huaiqihuang Granule plus glucocorticoid maybe has better effects than glucocorticoid alone.

The applied value of serum hepcidin in differential diagnosis of infection fevers versus tumor fevers was explored.A total of 432 fever patients were selected according to the domestic fever of unknown origin (FUO) diagnostic criteria from our hospital between June 2010 and November 2013.Venous blood samples were taken on the day 1,5,10 after admission.The infection group (98 cases) and the tumor group (50 cases) were set up based on the clinical and laboratory findings.ELISA was used to determine the serum hepcidin and IL-6 levels.SPSS 13.0 was used for statistical analysis.Hepcidin showed obvious descending trend on the 10th day in both the bacterial infection group (66 cases) and the virus infection group (32 cases),and the descending trend was similar to that of inflammatory indexes such as procalcitonin (PCT),hypersensitive C-reactive protein (h-CRP),erythrocyte sedimentation rate (ESR),white blood cell (WBC),and ferritin.Serum hepcidin showed no obvious differences in the tumor group on the day 1,5,10 after admission.In the infection groups,serum hepcidin was positively correlated with IL-6 (r=0.687,P=0.000) and CRP (r=0.487,P=0.026),but had a poor correlation with blood sedimentation,ferritin,PCT and WBC (P＞0.05).Monitoring dynamic changes of hepcidin and related inflammatory factors in patients with fever is expected to be used for clinical identification of infection fever and tumor fever.

OBJECTIVETo investigate the method and clinical outcome of reconstructing large pulp defects of the fingertips with a homodigital neurovascular island flap.
