3T3-L1 adipocytes transfected with TSH receptor (TSHR) shRNA were incubated with bovine TSH.The concentration of tumor necrosis factor (TNF)-α in culture medium was measured by enzyme linked immunosorbent asssy.Protein level of insulin receptor substrate 1 (IRS-1) was quantified by Western blotting.Tyrosine phosphorylation of IRS-1 was measured by immunoprecipitation.The results showed that 1 mIU/ml TSH significantly sitmulated TNF-α release in 3T3-L1 adipocytes [(341.85 ± 12.00 vs 522.67 ± 36.22) ng/L,P<0.01],along with the decreases in IRS-1 protein expression and its tyrosine phosphorylation (P< 0.01).These effects disappeared when TSHR expression was down-regulated with RNA interference in 3T3-L1 adipocytes.In addition,WP9QY,a TNF-α antagonist,blocked TSH-decreased IRS-1 expresssion.These results suggest that TSH downregulates IRS-1 protein expression and its tyrosine phosphorylation through stimulating production of TNF-α,and thus contributes to the development of insulin resistance.

The influences of the calmodulin antagonist chlorpromazine (CPZ), and calcium chanmel blocker nimodipine (NLMO) and their combination on cadmium (Cd) poisoning of mice were studied.A series of biochemical parameters including urinary enzyme activities, blood and urine Cd levels, metallothionein (MT) contents in liver and kidney, hepatic ultrastructure and Ca2+ -Mg2- AT Pase activitv in erythrocyte membrane were determined. Animal models for Cd poisoning were established by peritoneal injection of 1/5 LD50 CdCl2. The experimental groups were protected by administration of CPZ, NIMO and CPZ and NIMO in combination I h before the injection of CdCl2. Five days later, samples were collected for analysis. The data showed that CPZ could protect kidney tissue against Cd-induced damage, as the urinary y-glutamyl-traspeptidase (γ-GT) and N-acetyl-β-D-glucosaminidase (NAG) activities were reduced significantly. There was neither evidence of the protective effect of NIMO on kidney tissue nor an indication of a synergistic effecf of CPZ and NIMO.Both CPZ and NIMO showed a considerable protective effect against the decrease in Ca2+ -Mg2+ AT-Pase activity, and a synergistic action was observed. Cd content in blood was reduced significantly by CPZ or the combination of CPZ and NIMO, but elevated by NIMO. Both CPZ and NIMO considerably increased MT contents in livers and kidneys and ameliorated damaged to the hepatic ultrastructures caused by Cd. The results indicated that these inhibitors could protect mice against the toxic effects of Cd in liver and kidney tissues, while CPZ was more efficient than NIMO. The combination of CPZ and NIMO excrted a synergistic action. The protective action of these two drugs might be relevent to the function of MT.

OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.
METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.
RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).
CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.
