Objectives:To evaluate the efficiency of packing jaw defects with a composite of coral and bone marrow.　Methods:Twelve patients (9 with jaw cyst and 3 with ameloblastoma) underwent enucleation of jaw lesion and packing with a composite of coral and bone marrow.Repair of the bone defects was evaluated at 1 week,1,6 and 12 months postoperatively by clinical examination and X-ray films.　Results:Wound healing after the operations on 10 patients was uneventful,and definite ossification around the implanted material could be detected at 1 month postoperatively.A lot of bone formation and partial resorption of coral were observed at 6 months postoperatively.Complete resorption of coral and complete bone repair were obtained at 12 months postoperatively.Wound breakdown was observed on two other patients,and the composite had to be removed completely.　Conclusions:A composite of coral and bone marrow may enhances bone healing in jaw defects after cyst or ameloblastoma removal.

The traditional culture methods and the molecular biology methods were used to study the rhizosphere bacterial diversity between fusarium wilt resistant and susceptible watermelon. The results showed that the diversity and the equality of cultured rhizosphere bacteria of resistant watermelon were higher than those of the susceptible watermelon. The reason was that the cultured rhizosphere bacterial di- versity index H′ and 1/D of the resistant watermelon were higher than those of the susceptible watermelon and that the cultured rhizosphere bacterial equality index E of the resistant watermelon were higher than those of the susceptible watermelon. The dominant cultured bacterial genotypes were different between re- sistant and susceptible watermelon. The genotype 1 is the dominant genotype of resistant watermelon, con- sists 51.1%. The genotype 7 is the dominant genotype of susceptible watermelon, consists 58.7%.

Objective To analyze nucleic acid sequence homology of the 6 kb(pYC) plasmid of Yersina. pestis (Y. pestis) isolated from Yurman by searching GenBank. Method The search of sequence similarity was accomplished with BLAST.

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.

CONCLUSIONSuturing-assisted locking plate for the treatment of proximal humerus fractures in elderly, has advantages of less blood loss, simple fracture reduction and rapid recovery of shoulder joint, and is a effective method.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

Background Surgery is regarded as the most effective treatment to relieve pain and reduce complications in chronic pancreatitis (CP).Two major strategies exist:duodenum-preserving pancreatic head resection (DPPHR) and pancreatoduodenectomy (PD).Many studies suggest that DPPHR offers advantages during surgery and in the short-term; however,the long-term effects have not been thoroughly investigated.We analyzed the long-term outcomes of DPPHR and PD,over follow-up times of at least 1 year,to determine the optimal surgical treatment for CP.Methods We systemically reviewed all CP surgical treatment reports,and only included randomized controlled trials (RCT) comparing DPPHR and PD,excluding unqualified studies using several pre-specified criteria.When multiple publications of a single trial were found,the most comprehensive current data were selected.Characteristics of the study populations and long-term postoperative outcome parameters were collected.The quality of the studies and data was analyzed using RevMan 4.2 software.Results Five trials were qualified for meta-analysis,with 261 participants in total (114 in the DPPHR group and 147 in the PD group).There were no significant differences in the age,gender,or indications for surgery of each group.At the mean of 5.7-year (1-14 years) follow-up examination,DPPHR and PD resulted in equally effective pain relief,exocrine and endocrine function,and similar mortality rates (P ＞0.05); however,DPPHR patients had improved global quality of life and weight gain,and reduced diarrhea and fatigue (P ＜0.05).Conclusion DPPHR and PD result in equal pain relief,mortality,and pancreatic function; however,DPPHR provides superior long-term outcomes.
