BACKGROUNDTo repair late median nerve injury, many methods have been used in the past years. The aim of this study was to review a thirteen-year experience in restoration of thumb opposition by transposing flexor pollicis brevis muscle.

METHODSFrom July 1992 to August 2005, 63 patients without thumb opposition because of late median never injury were treated by transposing the flexor pollicis brevis muscle. All the patients had received primary nerve repair after the jnjury. The interval between the injury and the second operation was (1.87 +/- 2.31) years (6 months to 4.2 years). The patients were followed up for 3 to 48 [months mean (22.93 +/- 2.31) months]. A functional evaluation system designed in 1992 were used to estimate the outcomes of the patients.

RESULTSAll the patients gained excellent functional results without complications and disabilities during follow-up.

CONCLUSIONSRestoration of thumb opposition by transposing flexsor pollicis brevis muscle has the following advantages: 1. Operative trauma is minimal; 2. It is not necessary to transpose other tendons; 3. Except for the thumb in opposition, movements of other fingers and the wrist are not restricted postoperatively.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

Hypoxia is a common pathophysiological state especially in the processing inflammatory tissues cells due to hypoxia partial pressure caused by excessive oxygen consumption or insufficient oxygen supply. Hypoxia inducible factor(HIF) that regulates the transcription of downstream target genes in order to cope with the hypoxia environments is induced by various mechanisms in hypoxic state. Studies have demonstrated that HIF-α plays essential roles in the inflammatory response. This paper reviews the recent research that the roles and mechanisms of HIF-α in inflammation-associated diseases mediated by innate immune cells.

The aim of the present study was to investigate the influence of osmotic pressure on myocardial contractility and the possible mechanism. Electrical stimulation was used to excite papillary muscles of the left ventricle of Sprague-Dawley (SD) rats. The contractilities of myocardium in hyposmotic, isosmotic, and hyperosmotic perfusates were recorded. The influences of agonist and antagonist of the transient receptor potential vanilloid 4 (TRPV4) on the contractility of myocardium under hyposmotic, isosmotic and hyperosmotic conditions were observed. The results were as follows: (1) Compared with that under isosmotic condition (310 mOsm/L), the myocardial contractility was increased by 11.5%, 21.5% and 25.0% (P<0.05) under hyposmotic conditions when the osmotic pressure was at 290, 270 and 230 mOsm/L, respectively; and was decreased by 16.0%, 23.7% and 55.2% (P<0.05) under hyperosmotic conditions when the osmotic pressure was at 350, 370 and 390 mOsm/L, respectively. (2) When ruthenium red (RR), an antagonist of TRPV4, was added to the hyposmotic perfusate (270 mOsm/L), the positive inotropic effect of hyposmia was restrained by 36% (P<0.01); and when RR was added to the hyperosmotic perfusate (390 mOsm/L), the inhibitory effect of hyperosmia on myocardial contractility was increased by 56.1% (P<0.01). (3) When 4-α-phorbol-12,13-didecanoate (4α-PDD), an agonist of TRPV4, was added to the isosmotic perfusate (310 mOsm/L), the myocardial contractility did not change; and when 4α-PDD was added to the hyperosmotic perfusate (390 mOsm/L), the inhibition of myocardial contractility by hyperosmia was increased by 27.1% (P<0.01). These results obtained indicate that TRPV4 is possibly involved in the osmotic pressure-induced inotropic effect.

OBJECTIVETo investigate the effects of neuropeptide Y (NPY) Y1 receptor antagonist PD160170 in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and accelerating healing of femoral defect in rats.

METHODSThe third generation of rat BMSCs were treated with PBS (control) or 10, 10, or 10 mol/L NPY Y1 receptor antagonist PD160170. After 7 and 14 days of treatment, the cells were examined for osteogenic differentiation with alkaline phosphatase (ALP) and alizarin red staining. At 7 and 21 days of treatment, the mRNA and protein expressions of collagen type I (COLI), osteocalcin (OCN) and Runt-related transcription factor 2 (Runx2) in the cells were detected using q-PCR and Westem Blotting. In a male SD rat model (body weight 300∓20 g) of bilateral femoral condyle defects (2.5 mm in diameter), the effect of daily local injection of 0.2 mL PD160170 (10 and 10 mol/L, for 28 consecutive days) in promoting bone defect repair was evaluated with micro-CT scans.

RESULTSALP and alizarin red staining showed that the BMSCs treated with PD160170, at the optimal concentration of 10 mol/L, contained more intracellular cytoplasmic brown particles and mineralized nodules in extracellular matrix than PBS-treated cells. PD160170 (10 mol/L) significantly up-regulated the mRNA and protein expressions of COLI at day 7 and those of OCN and Runx2 at day 21 (P<0.05). In the rat models of femoral bone defect, the volume/tissue volume ratio, bone mineral density and the number of bone trabeculae were significantly greater in 10 mol/L PD160170 group than in the control group (P<0.05), but the bone trabecular thickness (P=0.07) and bone volume (P=0.35) were similar between the two groups.

CONCLUSIONNPY Y1 receptor antagonist PD160170 can promote osteogenic differentiation of BMSCs and healing of femoral defects in rats, suggesting the potential of therapeutic strategies targeting NPY Y1 receptor signaling in the prevention and treatment of bone fracture and osteoporosis.

OBJECTIVESTo investigate whether HDV ribozymes can intracellularly inhibit HCV RNA.

METHODSThe mammalian expression vectors, pC1-RzC1, pC1-RzC2 and pC1-RzC3, containing ribozymes cDNA of RzC1, RzC2, and RzC3, were constructed targeting different HCV-5' NCR-C RNA regions. Then the HCV-positive fetal hepatocytes were transfected with these plasmids using liposome-mediated method. The inhibitory effects of HDV ribozymes were evaluated by HCV RNA quantitation in cultured cells and the supernatants.

RESULTS(1) All the three HDV ribozymes were inserted into the expression vector. (2) Fetal hepatocytes were infected with HCV proven by RT-PCR and fluorescent quantitative PCR and expressed HCV NS3 and NS5 antigens by immunocytochemistry. (3) HDV ribozymes inhibited the activity of the target HCV RNA at expect positions in HCV-positive hepatocytes. At 0.5 micromol/L, the inhibitory rate of pC1-RzC1, pC1-RzC2, and pC1-RzC3 was 53.2%, 50.5 %, and 10.6% respectively. PC1-RzC1 was used continuously for one week, showing the inhibitory rate of 60.7%, 64.2%, 68.4%, 71.9%, 78.8% and 83.1% on the 2nd, 3rd, 4th, 5th, 6th and 7th day.

CONCLUSIONThe inhibitory activity of pC1-RzC1 (107-113nt) and pC1-RzC2 (268-274nt) is greater than that of pC1-RzC3 (345-351nt) in HCV-positive hepatocytes.
