OBJECTIVETo discuss operative methods and effects for Müller-Weiss disease.
METHODSFrom March 2005 to May 2011, 15 patients were operated. There were 2 males and 13 females, with an average age of 51.8 years (range, 26 to 62 years). The preoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was (42 ± 13) points. According to the Maceira Staging system, 1 foot was grade 2, 6 feet were grade 3, 4 feet were grade 4, and 4 feet were grade 5. The technique consisted of arthrodesis of the talonaviculocuneiform joints with plate, arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint with plate, or triple arthrodesis with screws, according to the preoperative evaluation.
RESULTSTen feet were treated with arthrodesis of the talonaviculocuneiform joints, 3 feet were treated with arthrodesis of the talonavicular joint and arthrorisis of naviculocuneiform joint and 2 feet were treated with triple arthrodesis. Two patients were lost to follow-up. The average follow-up after operation was 19.2 months (range, 9 to 38 months). All feet were solid fusion and the average duration of union was 13.3 weeks (range, 12-16 weeks). The AOFAS ankle-hindfoot score at the last follow-up was (83 ± 6) points. Two feet were excellent, 10 feet were good, and 1 foot was fair. The length of feet was (14.2 ± 1.0) cm before surgery and (15.7 ± 0.9) cm at the last follow-up (t = 11.570, P < 0.05). The Meary's angle was -6.1° ± 13.1°before surgery and 1.1° ± 3.0° at the last follow-up (t = 2.248, P < 0.05). The talocalcaneal angle was 4.5° ± 2.2° before surgery and 18.0° ± 4.0° at the last follow-up (t = 11.700, P < 0.05). One foot had breakage of the plate and screws at arthrorisis of naviculocuneiform joint and none had complications related to the incision.
CONCLUSIONOperations for Müller-Weiss disease, according to concrete conditions using different therapeutic program, may achieve a satisfactory outcome.

OBJECTIVETo study the effect of tanshinone II A on the cell signal transduction system protein kinase B (Akt) in rats with hypertrophy of the myocardium induced by partial constriction of the thoracic aorta.
METHODSRat models of myocardial hypertrophy were established by the thoracic aorta partial constriction method. Forty-eight rats were randomly divided into the sham-operative group, the model group, the valsartan treatment group, and the low-, medium-, and high-dose tanshinone treatment groups. The heart mass index (HMI), left ventricular mass index (LVMI), ejection fraction (EF), left ventricular posterior wall (LVPW), and interventricular septal thickness (IVS) were detected by high-frequency ultrasonography. The myocardial fiber diameter (MFD) was detected by HE staining, and the contents of p-Akt and p-Gsk3beta in the myocardium were detected by Western blot.
RESULTSCompared with the sham-operative group, the levels of HMI, LVMI, LVPW, IVS, and MFD were increased respectively in the other groups (P<0.05); the contents of p-Akt and p-Gsk3beta were also increased in the other groups. Compared with the model group, the levels of HMI, LVMI, LVPW, IVS, and MFD were decreased respectively in all treatment groups (P<0.05); the contents of p-Akt and p-Gsk3beta were decreased in all treatment groups as well. There was no significant difference, however, among the low-, medium-, and high-dose tanshinone treatment groups and the valsartan treatment group (P>0.05).
CONCLUSIONTanshinone II A can prevent myocardial hypertrophy by its action on the protein kinase B (Akt) signaling pathway.

7.Effects of W-7 on the expression of GRP78 and neuronal apoptosis in immature rat hippocampus after status convulsion.
Chinese Journal of Contemporary Pediatrics 2011;13(1):44-49
OBJECTIVETo investigate the effects of the calmodulin inhibitor W-7 on the expression of the key marker of ERS GRP78 and neuronal apoptosis in the immature rat hippocampus after status convulsion (SC).
METHODSOne hundred and seventeen male Sprague-Dawley rats aged 19-21 days were randomly divided into three groups: normal saline control (control), SC with and without W-7 pretreatment. Each of the 3 groups was further subdivided into subgroups sacrificed at 4, 24 and 48 hrs. SC model was prepared using lithium-pilocarpine. GRP78 mRNA expression in the hippocampus was detected by semiquantitative reverse transcription-polymerase chain reaction (RT-PCR). GRP78 protein was ascertained by immunohistochemistry. Neuronal apoptosis was observed with TdT-mediated dUTP nick end labeling (TUNEL).
RESULTSThe expression of GRP78 mRNA was significantly increased in the non-pretreated SC group compared with the control group 24 hrs after injection of saline or lithium-pilocarpine (P<0.01), and the expression of GRP78 protein also increased markedly in the seizure group compared with the control group 24 and 48 hrs after the injection (P<0.01). The expression of GRP78 mRNA and protein in the W-7 pretreatment group was significantly higher than both the control and the non-pretreated seizure groups 24 and 48 hrs after injection. The TUNEL positive cells in the hippocampus CA1 in the non-pretreated SC group 24 and 48 hrs after injection (21.0 ± 2.5 and 29.4 ± 2.8, respectively) were increased compared to the control group (7.1 ± 1.4 and 7.3 ± 1.6, respectively; P<0.01). W-7 pretreatment decreased TUNEL positive cells to 15.0 ± 2.5 and 20.0 ± 2.9 at 24 and 48 hrs after injection compared to the non-pretreated seizure group (P<0.01), but the number of TUNEL positive cells in the W-7 pretreatment group remained significantly greater than in the control group (P<0.01).
CONCLUSIONSW-7 may up-regulate the expression of GRP78 and reduce the number of apoptotic neurons, thus provides a neuroprotective effect against brain damage following SC.
