Armillariella tabescens EJLY2098 was capable of secreting p-mannanase by konjac inducement. A 34 orthogonal design was applied to determine the optimum medium of inducing mannanase by Armillariella tabescens EJLY2098. The results suggested that Armillariella tabescens EJLY2098 secreted the high-activity enzyme in the optimum medium, which was composed of 2% konjac, 1% peptone, 25% potato juice,0.3% KH2PO4,15% MgSO4?7H2O, 0.01% VitB1. Purified by DEAE-anion exchange chromatography, two eluting peaks (P1 and P2) with the p-mannanase activity were obtained, and one of them (named?-mannanase P2) was a single band by the SDS-PAGE, and the molecular weight of?-mannanase P2 was 78. 9kDa. The isoelectric point of?-mannanase P2 was estimated to be 4.0-4. 1. The optimum activity for the enzyme was found at 60℃and pH4. 0 - 6. 0, and the enzyme was stable between pH4. 5 - 6. 0. The activity of?-mannanase P2 were enhanced by Na+ and Ba2+ . This?-mannanase can be used in feed industy. a new fungi secreting?-mannanase was obtained, providing an important base for cloning mannanase gene and constructing recombin microbe expressing?-mannanase .

OBJECTIVEThe research aimed at studying the biological characteristics of rhizobia isolated from Abrus cantoniensis.

METHODThe rhizobia strains, isolated from different environments in Guangxi, were studied for their growing characters and the generation time. They were also compared for survival capabilities under stresses caused by NaCl, pH, temperature, and different kinds and concentration of antibiotics.

RESULTThe strains obtained from A. cantoniensis in subtropical zone produced alkali in YMA medium, the average generation time was 14.8 hours, and thus they belong to slow-growing rhizobia. Rhizobia strains differed greatly in respect to tolerance of high temperature, adaptability of acidic environment and sensitivity to four antibiotics, but they had the same abilities of using different carbon and nitrogen sources. After 70 days from inoculated strains, the seedling formed nodules on the root (85.0%), and the dry matter of vine was increased by 51.1%.

CONCLUSIONThe rhizobia strains isolated from different ecological environments are good germplasm resources of tolerances to high temperature and acidic environment. The research will greatly help utilize the rhizobia resources and enhance the quality of crude drugs of medicinal leguminosae.

LFA-1/ICAM-1 costimulation plays an important role in immunologic reaction of many different T cell populations. After TCR/CD3 complex cross-linking MHC/peptide, LFA-1, expressed on T cell increases a higher affinity and avidity for ICAM-1 rapidly. LFA-1 is a key molecule in formation of the immune synapse. LFA-1/ICAM-1 costimulation can engage various signaling events of T cell by up-regulating the activities of PI 3-kinase, sphingomyelinase, and c-Jun NH2-terminal kinase. With the costimulation of LFA-1/ICAM-1, engagement of TCR molecules results in a significant increase of T cell activities, including higher Th1 cytokines production, strongly proliferative response and higher T cell cytotoxicity.

OBJECTIVETo explore clinical effects of suturing-assisted locking plate in treating elderly proximal humeral fractures.

METHODSFrom January 2005 to January 2013, 55 elderly patients with three- and four-part fractures of proximal humeral fractures were divided into treatment group and control group. In treatment group, there were 31 patients including 12 males, and 19 females aged from 65 to 85 with an average of (74.00±5.42) years old, and treated with suturing-assisted locking plates; 19 patients were Neer 3-part fractures, and 12 patients were Neer 4-part fractures of proximal humerus; 23 patients were suffered from low-energy injuries and 8 patients were caused by high-energy injuries. In control group, there were 24 patients including 7 males, and 17 females aged from 65 to 85 with an average of (72.79±5.34) years old, and treated with locking plates; 16 patients were Neer 3-part fractures, and 8 patients were Neer 4-part fractures of proximal humerus; 17 patients were suffered from low-energy injuries and 7 patients were caused by high-energy injuries. Operative time, blood loss during operation, and bone healing time between two groups were observed and compared. Postoperative Neer scoring were used to evaluate recovery of shoulder joint function.

RESULTSAll patients were followed up from 6 to 24 months with an average of 16.1 months. In treatment group, blood loss was (495.806±143.150) ml, function of Neer scoring was 22.645±2.443, range of action was 18.194±2.613, anatomy was 7.935±1.504 and total score of Neer scoring was 77.161±8.335; while in control group, blood loss was (641.667±169.851) ml, function of Neer scoring was 13.958±1.989, range of action was 13.083±2.165, anatomy was 5.500±1.978 and total score of Neer scoring was 58.792±7.313. There were sigificant difference between two groups in these indexes.

OBJECTIVEThe research aimed at the effects of different nitrogenous compounds on growth and nodulation of Abrus cantoniensis.

METHODAfter the seedlings of the herb were inoculated with rhizobia in potted culture, they were supplied with nutrition solutions which contained the three nitrogenous compounds, KNO3, NH4NO3, (NH4)2SO4 of different nitrogen concentration. The growth and nodulation of seedlings was determined after 70 days.

RESULTDifferent nitrogenous compounds were able to enhance the vegetable growth of seedlings variously. The effect of (NH4)2SO4 and NH4NO3 on growth was better than that of KNO3. Seedlings nodulation was obviously inhibited by these nitrogenous compounds. Their inhibitory effects ranked NH4NO3 > (NH4)2SO4 > KNO3. The treatments of KNO3 and the lower concentration treatments of NH4NO3 and (NH4)2 SO4 didn't inhibit the nodulation of seedlings, but the higher concentration treatment of NH4NO3 and (NH4)2SO4 severely inhibited nodulation or even made a no formation of nodule.

CONCLUSIONThe results showed that ammonium nitrogen the higher inhibitory ability to the nodulation of seedlings of A. cantoniensis than nitrate nitrogen. Therefore, the application of ammonium nitrogen fertilizer should be controlled in culture of the herb, which is in favor of increasing the function of biological nitrogen fixation and the quality of the medicinal materials of A. cantoniensis.

OBJECTIVETo evaluate the effect of meatoplasty with the pedicle flap in the treatment of meatal stenosis secondary to chronic balanitis.

METHODSWe retrospectively analyzed 32 cases of meatal stenosis secondary to chronic balanitis treated by meato- plasty with the pedicle flap. All the patients had a history of chronic balanitis and had received meatal dilatation or simple ventral mea- totomy without significant effect. Their mean maximum urinary flow rate (Qmax) was (4.3 ± 2.4) ml/s. During the operation, A "/\"-shaped incision was made in the healthy epidermis and a flap was harvested from the frenulum. After complete removal of the scar, the flap was placed into the urethral wall, followed by reconstruction of the external urethral orifice.

RESULTSThe patients were fol- lowed up for 6 to 30 months, which revealed smooth urination in all the patients with Qmax of (26.7 ± 4.5) ml/s and normal erectile function and uresiesthesis.

CONCLUSIONWith little invasiveness and few complications, meatoplasty with the pedicle flap is an ideal surgical method for the treatment of meatal stenosis secondary to chronic balanitis. However, there might be some change in the normal appearance of the balanus postoperatively, and its long-term effect needs further observation.

Tumor necrosis factor(TNF-alpha) plays an improtant role in the process of anti-infection and anti-cancer. It can both protect and make damage to the host. In order to find new way of inhibiting its host-damaging activity, An E. coli flagella displayed random peptide library was constructed and TNF-alpha antagonist peptides were screened using the peptide library. After 5 rounds of panning and DNA sequencing, six peptide sequences were obtained. Two of them(TBP2, TBP3) have the same sequence frame of V--N-WG. After primary comparation of TNF-alpha binding ability, four peptides were synthesised and purified with RP-HPLC. The activity of inhibiting TNF-alpha was detected with L929 cell and MTT method. The data show that TBP2 and TBP3 can inhibit 90% of TNF-alpha activity when TNF-alpha gives about 30% cell toxicity on L929. The two sequences have not been reported.
