Objective To study the protective effect and mechanism of Inonotus obliquus polysaccharide on liver injury induced by isoniazid( INH) combined with rifampicin( RFP) in mice. Methods Forty-eight mice were randomly divided into six groups ( control, model, huganpian, Inonotus obliquus polysaccharide at low, middle, and high dose ) . The mice were administered orally with isoniazid and rifampicin simultaneously except the control. After 2 h,the control and model groups were administered with normal saline,and others were treated with huganpian and Inonotus obliquus polysaccharide,respectively,once a day for 2 weeks. The liver index and serum levels of ALT and AST,malondialdehyde(MDA),superoxide dismutase(SOD) and glutathione peroxidase( GPx) were measured. Pathology examination of liver tissue was performed. Results The activities of ALT and AST, liver index, content of MDA in liver homogenate of mice treated with Inonotus obliquus polysaccharide and huganpian decreased obviously, while the liver SOD activity increased. Histopathological exzamination showed that Inonotus obliquus polysaccharide alleviated the degeneration and necrosis of hepatic cells. Conclusion Inonotus obliquus polysaccharide shows protective effects on mice with hepatic toxic injury induced by isoniazid and rifampicin,which maybe due to its antioxidation effect.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Mycoepoxydiene is a novel antitumor agent extracted from marine lignicolous fungi HLY-2, which is Diaporthe phaseolorum by molecule identification. The medium optimization for mycoepoxydiene by orthogonal design and the comparison of submerged fermentation and solid state fermentation were studied. The rusult is that the maximal yield of the compound is 543mg/L, which is 43 times compared to the customary half-seawater PD medium and 15 times to the best submerged condition. This optimum culture medium included potato 250g/L, seawater 300mL/L, glucose 30g/L, lactose 50g/L, KH_ 2 PO_ 4 0.65mmol/L and (NH_ 4 )_ 2 SO_ 4 1g/L in the solid state condition. Differentiation analysis between submerged and solid state fermentation, and antitumor activity of these ferment products were also studied. The antitumor activity of products of the optimum medium approached the pure compound.

OBJECTIVETo observe the hair follicle regeneration after implantation of hair follicle cells into the subcutis of nude mice.

METHODSThe cultured hair papilla cells,dermal sheath cells and fibroblast of human scalp were mixed with the cells of hair follicle epithelium in different ratio, and then implanted into the subcutis of nude mice. The regeneration of hair follicle was observed.

RESULTThe hair follicle-like structure was formed in cluster where the cultured hair follicle epithelium cells were mixed with hair papilla cells. But no hair follicles were formed where the hair follicle epithelium was implanted with dermal sheath cells or fibroblasts.

CONCLUSIONThe hair follicle-like structure is generated in vivo when the mixed cells of early passages cultured hair papilla cells with hair follicle epithelium are implanted into the subcutis of nude mice.

AIM AND METHODSThe distribution of ErbB2 in mouse testis, epididymidis, ovaries, oocyte-cumulus cells-complexes in oviducts and sperms was investigated immunohistochemically. To study the effect of c-erbB2 on mouse fertilization in vitro, various concentrations of c-erbB2 antisense oligonucleotides (c-erbB2 ASODNs) were incubated with sperms and oocyte-cumulus cells-complexes during fertilization in vitro. To explore possible mechanisms involved in fertilization, the relationship between c-erbB2 ASODNs and GABA, or dbcAMP, or verapamil during fertilization in vitro was also observed.

RESULTSErbB2 oncoprotein was observed in epithelial cells in epididymis, sperms and cumulus cells. C-erbB2 ASODNs inhibited the rate of fertilization in vitro in a dose-dependent way. The fertilization rate of the control group, low (5 micromol/L), medium (10 micromol/L), high (20 micromol/L) concentration c-erbB2 ASODNs group, and nonsense at oligonucleotides group (20 micromol/L) was 38.3%, 19.6%, 10.7%, 5.0%, and 33.8% respectively. Integral optical density immunostaining of ErbB2 in sperms was notably reduced. Medium and high concentration of c-erbB2 ASODNs notably inhibited cumulus cells adhering to inner wall of Petri dish. Treated alone with GABA or dbcAMP, the rate of fertilization was increased. Both GABA and dbcAMP partially inversed the ASODNs inhibition effect on fertilization rate, but neither of them showed significant effect on sperm integral optical density of ErbB2 immunostaining. In contrast, verapamil inhibited fertilization rate. Co-treated with c-erbB2 ASODN, verapamil showed synergic inhibiting effect on fertilization with c-erbB2 ASODN. Verapamil also inhibited the expression of c-erbB2 in sperms.

CONCLUSIONIt is suggested that c-erbB2 is closely correlated with fertilization. Ca2+ may inhibit fertilization in vitro through regulation the expression of c-erbB2 gene in sperm cells, while both of GABA and dbcAMP may affect the process of fertilization through the way other than c-erbB2 expression in sperm cells.

BACKGROUND:Our previous work has demonstrated that bone marrow mesenchymal stem cels (BMSCs) transplantation can improve the heart function of rats with myocardial infarction. However, the overal efficacy is not satisfactory. OBJECTIVE: To adopt pioglitazone as a peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist combined with BMSCs transplantation therapy, thereby further improving cardiac function of rats with myocardial infarction as wel as investigating the relevant mechanisms. METHODS:Twenty Sprague-Dawley rats with myocardial infarction were induced by the left anterior descending coronary artery ligation. The animals were randomized into two groups: BMSCs and BMSCs+pioglitazone. Two weeks later, al the animals received the injection of BMSCs labeled with PKH26 in PBS into the local infarct zone, and then pioglitazone (3 mg/kg/d) was given by the oral gavage for 2 weeks in the BMSCs+pioglitazone group after the cel transplantation. After 2 weeks of cel transplantation, cardiac functions were evaluated by echocardiography. The expressions of PPAR-γ, Connexin 43 and molecules in TGF-β1/SMAD signaling pathway were examined in different areas of the left ventricle from each harvested heart using immunofluorescent staining, western blot assay and qRT-PCR. RESULTS AND CONCLUSION:There were no differences in the baseline parameters of cardiac function between the two groups. At 2 weeks after cel transplantation, the left ventricular internal diameter at end-diastole, left ventricular internal diameter at end-systole and left ventricular ejection fraction were significantly improved in the BMSCs+ pioglitazone group; the expressions of PPAR-γ and Connexin 43 were distinctly increased in different zones of the left ventricle; the levels of TGF-β1, SMAD2 and SMAD3 were obviously attenuated in the infarct zone and border zone. The above-mentioned findings suggest that pioglitazone, a PPAR-γ agonist, can enhance BMSCs potential in improvingthe heart function after myocardial infarction, and PPAR-γ may elevate the expression of Connexin 43via the blockade of the TGF-β1/SMAD signaling pathway in the procedure.

To investigate the relationship of blood ATP content with temperature and time of preservation and to establish its mathematical model, adenosine triphosphate (ATP) concentration was applied as the index of the quality of erythrocytes; systematical study on variation of blood preserved in a series of different temperatures from 4 degrees C to 32 degrees C was performed, and a series of experimental data were obtained. The results showed that when the ATP concentration y = f (d, t, s) in preserved blood was given as the continuous function of the time (d), the temperature (t) and the initiate ATP concentration (s), the model was fitted with the theory of linearity regression in symbolic statistics, and the general mathematical physical equation of the variation of preserved blood quality was deduced. According to the equation, the whole blood in CPDA-1 solution could be efficiently stored for 35, 35, 29, 22, 18, 18, 13, 8, 7, 6, 6, 5, 4, 4 and 3 days in 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 and 32 degrees C, respectively. In conclusion, the general tendency of the variation of preserved blood quality according to the temperature and the time was systematically disclosed for the first time, which would be propitious to estimate the blood quality in various temperatures and to instruct clinical blood transfusion.
