Four cellulolytic strains, which can be used as feed additive, were studied under the conditions of various temperature, incubation time, and anaerobic process, and examined the changes of their cell protein content, cellulase and hemi-cellulase activity. The results show: 1) The maximum cellulolytic enzyme activities were observed incubation 20h; 2) Constant medium temperature 28℃ was adequate to the growth of the 4 strains ; 3) anaerobic condition, 39℃±2℃ and fermentation 12h, 24h, 36h, the tested strains can growth well in PDA plate, however, the cellulolytic enzyme activities and growth of the tested strains were influenced adversely when fermentation 48h. The experiment provide many important basis for the strains production, storage and utilization.

Objective To explore ear reconstruction using autologous rib cartilage ear framework by multi-layer spliced sculpture in microtia patients.Methods From Feb 2010 to May 2011,29 microtia patients were subjected to ear reconstruction using autologous rib cartilage ear framwork by four-layer spliced sculpture.Results In one operation 29 patients achieved 2 cm transverse height of reconstructed ears which were basically coincidence with the normal side.Patents and their families were all satisfied with the results.Follow-up of 3-12 months showed that only 1 case reconstructed-ear height was significantly lower transverse process.Owing to sleeping position,the patient did not protect the reconstructed ear,leading to frequent reconstructed-ear pressure.Conclusions The method of multi-layer spliced sculpture autologous rib cartilage ear reconstruction has good clinical effect.It can make reconstructed ear reach nomal transverse height and avoid the third rib cartilage transplant operation to continue increasing the transvers height.

1 approximately 3 days old Piglet's primary preadipocytes in vitro were cultured and treated with 0micromol/L (control group), 10microlmol/L (lower dose group), 20micromol/L(middle dose group) and 50micromol/L, 100micromol/L (higher dose group) RES. Cell proliferation and viability were analyzed by MTT assay. The degree of differentiation and adipogenesis were measured by Oil Red O staining extraction assay and the expression of Sirt1 (sirtuin) mRNA were detected by RT-PCR. The results showed the optical density (OD) of MTT and Oil Red O staining were all decreased, especially treated by 50micromol/L, 100micromol/L RES at 72h and 96h (P < 0.01); the ratio of OD of the expression of Sirt1 mRNA to that of beta-actin mRNA were increased after treated by 100micromol/L RES (P < 0.01). RES can inhibit proliferation and differentiation of pig preadipocytes in certain degree. Higher dose of RES can markedly decrease adipogenesis and prevent preadipocytes differentiation into adipocytes, which may be in part associated with its effect on increasing the expression of Sirt1 mRNA.

OBJECTIVETo evaluate the therapeutic effect of acupuncture-moxibustion and Tuina massage for treatment of sub-health.
METHODSA systematic evaluation on randomized controlled trial, quasi-randomized control trial or controlled clinical trial of treatment of sub-health with acupuncture-moxibustion and Tuina was carried out according to the assessment methods recommended by the Cochrane Collaboration.
RESULTSThere are totally 9 articles and 937 subjects met the inclusion criteria and are included into the assessment system. The average quality of methodologies adopted is not so high, and with many limitations. Meta-analysis or descriptive analysis on the data collected: (1) General effect: Tuina massage therapy is better than auricular-point-pressing therapy; acupuncture is better than self health care; acupoint injection is better than intramuscular injection, Tuina is similar to Chinese herb. (2) Quality of life and pain score: Tuina is better than blank control. (3) Individual effect: the effect of Tuina massage on lassitude is better than acupuncture. (4) Effect on sleep quality index: Tuina massage is better than acupuncture.
CONCLUSIONThere are not enough evidences to approve that the effect of acupuncture-moxibustion and Tuina massage on sub-health is better than that of other therapies. Therefore, more high quality randomized controlled trials with strict and scientific designation are necessary for obtaining more and better evidences.

Objective To discuss the application of flipped classroom teaching model in the teaching reform of Science of Tuina Technique based on MOOC; To provide references for promoting teaching quality of Science of Tuina Technique. Methods Flipped classroom teaching model based on MOOC and traditional teaching model were conducted in 2 classes of 2013 in Guangxi University of Chinese Medicine, one experimental groups and one control group. After the end of the course, theoretical knowledge and techniques skill scores of the two classes were compared. Questionnaire was given to students in the experimental class to understand their satisfaction towards flipped classroom based on MOOC. Results The scores of theoretical knowledge, performance demonstration test results, mannequin test and practices mechanics test of experimental group were high than the control group, with statistical significance (P<0.05). The results of questionnaire showed that the satisfaction of students in the experimental group towards flipped classroom based on MOOC was 95. Conclusion Flipped classroom teaching model based on MOOC applied to the teaching of Science of Tuina Technique can improve the students' learning interest and initiative, and then improve academic performance.

OBJECTIVE:
To explore phenotypic and mutational characteristics of a pedigree affected with autosomal dominant Charcot-Marie-Tooth disease (CMT) and nephropathy.
METHODS:
Clinical data of the proband and his family members was collected. Electrophysiology, renal biopsy and next-generation sequencing were carried out for the proband.
RESULTS:
The proband presented with distal lower limb weakness and proteinuria in childhood. His mother and brother had similar symptoms. Electrophysiological test of the proband revealed demyelination and axonal changes in both motor and sensory nerves. Renal biopsy suggested focal segmental glomerulosclerosis. Genetic testing revealed a heterozygous c.341G>A (p.G114D) mutation in exon 2 of the INF2 gene.
CONCLUSION
The phenotypic feature of the pedigree is autosomal dominant intermediate CMT and focal segmental glomerulosclerosis, which may be attributed to the c.341G>A mutation of the INF2 gene.

BACKGROUNDHepatoblastoma (HB) is a rare childhood tumor. We investigated the effect of intraoperative management of the intrahepatic major vessels in children with HB.
METHODSBetween April 2005 and August 2012, surgical resection was performed on 50 children with hepatoblastoma. These children were divided into a vessel-ligation group (n = 20) and a vessel-repair group (n = 30). In the vessel-ligation group, the intrahepatic major vessels were ligated and removed together with the tumor and the affected liver lobe/liver parenchyma. In the vessel-repair group, the affected intrahepatic major vessels were dissected and preserved as much as possible and the normal liver lobe/liver parenchyma and blood supply from these vessels were also preserved. The outcomes were analyzed by postoperative follow-up.
RESULTSIn the vessel-ligation group, two patients gave up surgery, six patients underwent palliative resection, and 12 patients underwent en bloc resection; four patients died of liver failure and eight patients fully recovered and were discharged. In the vessel-repair group, all 30 patients underwent en bloc resection and were discharged after satisfactory healing. After a follow-up time of 5 - 36 months (median: 20 months), two patient in the vessel-ligation group survived and 22 patients in the vessel-repair group survived.
CONCLUSIONSPatients with HB can be successfully treated by tumor resection with vascular repair. This method prevents postoperative liver failure, ensures patient safety during the perioperative period, and allows for early chemotherapy.
