ObjectiveTo investigate the clinical efficacy of Jin’s eye three-needle acupuncture as main therapy for acquired paralytic strabismus.MethodSeventy patients with acquired paralytic strabismus were randomly allocated to acupuncture and Western medication groups. Both groups of enrolled patients took prednisone,methycobal, vitamin B1and vitamin B12. In addition, theacupuncture group received Jin’s eye three-needle acupuncture as main therapy. The clinical therapeutic effects and adverse reactions were observed after four and eight weeks of treatment.ResultThe total efficacy rate was 75.0% in the acupuncture group and 51.6% in the Western medication group after four weeks of treatment and 90.6% in the acupuncture group and 77.4% in the Western medication group after eight weeks of treatment. There were statistically significant differences between the two groups (P<0.05). Patients in the acupuncture group occasionally had acupuncture syncope and local blood stasis. Both groups had no special discomforts.ConclusionJin’s eye three-needle acupuncture has a quick and definite therapeutic effect on acquired paralytic strabismus.

Objective To study the simple preparation method and structure of nano-hydroxyapatite/collagen composite, to investigate new substitute of repairing bone for using in tissue engineering. Methods Porous nano-hydroxyapatite was made of Ca (OH)2 and H3PO4. Collagen was drawn from fresh adult bovine tendon. The two materials were prepared into biomembrane through the glutaraldehyde and freeze-drying. The crystallite phase, micro-morphology, structure, crystallite size of the composite were examined by XRD and scanning electronic microscop (SEM). Results The results showed that the composite structure was porous and consisted of nano-hydroxyapatite (10 nm ? 50 nm - 20 nm ? 80 nm) and collagen fiber. The crystallite phases and size of the composite was similar to that of natural bone. Conclusion The porous nano-hydroxyapatite /collagen composite is expected to be an ideal substitute of repairing bone.

Collagen fibrils and hydroxyapatite might recognize each other at the mesoscale by multiple cooperative interactions due to their intrinsically repetitive structured surfaces, and thus effectively directing the biomineralization, a biological process involving regulating the growth of bones, teeth and other organs. In this work, we developed a simple technique to prepare nanowire arrays of biological macromolecules by reversely using the biomineralization mechanism, with results similar to the hot wall epitaxy, a molecular beam deposition technique under vacuum. With this technique, we successfully cultured 5-10 μg/mL rat tail type I collagen monomer solutions into collagen nanowire arrays on the mica (001) lattice plane along one unique direction across the whole cleavage surface. The atomic force microscope experiments indicated that the nanowires in the arrays became more crowded with higher monomer concentration, but their width and height remained unchanged, about 60.0 nm and 1.5 nm, respectively. The collagen nanowire coating enhanced the hydrophilicity of the mica surface, reducing the contact angle from 25.8° to 9.5°. Based on the characterization results of electron back scattering diffraction and transmission electron microscope, the collagen nanowires were most likely to be oriented along the mica [110] direction, which validated the quasiepitaxial growth mechanism in more details.

[Objective] To investigate the change of liver histology, proliferation of BDEC, and expression of TGF-β in different stages of liver chelestusis. [Methods] ①Rat cholestatic livers were induced by common bile duct ligation (BDL) and separated into 3 groups, namely control group (DO), 7 days after BDL group (DT), and 18 days after BDL group (D18). ② Histological changes of livers in different groups were evaluated based on Knodell HAI score. ③ Real-time PCR was used to detect the expression of TGF-β in liver tissue and isolated BDEC in different groups. ④ Statistically analyzing the correlation between Knedell HAl score and the levels of TGF-β_1 mRNA. ⑤ In vitro study was performed to investigate the effect of TGF-β_1 on an immortalized mouse intrahepatic bililary epithelial cell line (mIBEC). [Results] (I) Knedell HAI score and the proliferation of intrahepatic bile ducts increased as the liver cholestasis aggravated. ② The levels of TGF-β_1, TGF-β_2, and TGF-β_3 mRNA were significantly up-regulated in liver tissues and BDEC as the liver cholestasis aggravated. ③ Positive correlation was found between Knedell fibrotic score and the levels of TGF-β_1 mRNA in liver tissues and BDEC(r=0.9376, P<0.05 and r=0.9682, P < 0.01). ④ In vitro study showed that TGF-β_1 inhibited the proliferation of mIBEC. [Conclusion] ① Liver injury, biliary proliferation, and the levels of TGF-β mRNA expression increased as liver cholestasis aggravated. ② The interaction of TGF-β_1 and BDEC plays an important role in the pathogenesis of BDL induced cholestatic liver disease. ④ Up-regulated expression of TGF-β_1 mRNA in the proliferated BDEC participates in the formation of BDL induced cholestatic liver fibrosis.

12 strains of H2-producing bacteria were isolated and purified from anaerobic sludge, aerobic sludge and river bottom sludge by Hungate method. A new species of high efficient hydrogen production bacterium Enterococcus sp. LG1 (registration number: EU258743 ) was studied deeply. It was showed that the Enterococcus sp. LG1 was an anaerobic and Gram-negative bacterium. Sequence analysis of this type of clones showed that it was affiliated with the genus Enterococcus and it was not reported yet in other paper at present. Meanwhile, batch tests of anaerobic fermentative hydrogen production by Enterococcus sp. LG1 were investigated by using sterilization pretreated sludge as substrate. The changes of soluble COD, protein, carbohydrate and pH value during hydrogen fermentation were monitored. It was found that only hydrogen and carbon dioxide were produced by this strain and no methane was detected during fermentation. The maximal hydrogen yield was 36.48 mL/g TCOD and the hydrogen concentration in the gas phase was 73.5%. The Enterococcus sp. LG1 was a butyrate fermentation bacteria analyzed by metabolites.
