Objective To explore an easily-controllable, environmentally-friendly method for synthesizing monastrol and its derivatives. Methods Monastrol and its derivatives were synthesized using (substituted) benzaldehyde, ethyl acetoacetate and thiourea (or urea) as the material through a Biginelli reaction catalyzed by green room temperature ionic liquid 1-butyl-3- methylimidazolium-L-camphorsulfonate under microwave irradiation without solvent. Results The green room temperature ionic liquid 1-butyl-3-methylimidazolium-L-camphorsulfonate catalyzed Biginelli reaction in obtaining the title compound under microwave irradiation without solvent. The process was easy to operate, time saving and environmentally-friendly. Conclusion Microwave-accelerated solvent-free Biginelli reaction using green room temperature ionic liquid 1-butyl-3-methylimidazolium-L- camphorsulfonate as catalyst is a convenient and environmentally-friendly method for synthesizing monastrol and its derivatives.

Objective To evaluate the clinical effects in treating periprosthetic femoral fractures classified Vancouver B2 with a cementless modular revision femoral prosthesis.Methods Twenty-six patients (7 males and 19 females with mean age of 66.5 years,range 60-69 years) who suffered from periprosthetic femoral fractures classified Vancouver B2 were treated with a cementless modular revision femoral prosthesis in hip revision and open reduction and internal fixation with cables or plates from March 2007 to February 2014.The previous femoral prostheses included 21 cementless and 5 cemented hip stems.The period from former procedures to fractures was 16 months,range from 7 to 32 months.Harris hip scores and numerical rating scales were analyzed statistically.Time of leaving bed,discharging,fracture union postoperative complications and radiographic imaging were also recorded.Results The operation duration were 143 (range 105-165) minutes.Blood loss volume was 450 (range 270-780) ml.Blood transfusion volume were 330 (range 0-800) ml.All patients were followed up at least two years,averagely 3.5 years after surgeries.All fractures healed at 6.5 (range 3-12) months averagely after surgeries.Harris hip scores improved significantly from 11.8±2.5 before surgeries to 80.3±5.3 one month and to 91.4±7.3 six months after surgeries separately (F=0.715,P=0.001).Numerical rating scales were 9.6±0.3,9.4±0.4 and 9.1±0.7 points averagely in aspect of information acquisition,postoperative pain control and function recovery respectively one month after surgeries.Average time of leaving bed and discharging from surgeries was 68.3 (range 51-75) hours and 6.5 (range 5-9) days respectively.No postoperative complications was found except dislocation in 1 hip,lower limb discrepancy in 1 hip,DVT in 1 hip,and heterotopic ossification in 3 hips.Conclusion Due to achieving prosthetic stability and fracture union,periprosthetic femoral fractures classified Vancouver B2 treated with a cementless modular revision femoral prosthesis combined with open reduction and internal fixation with cables or plates can reach good clinical outcomes.

Pancreatic cancer remains a devastating disease with a 5-year survival rate of less than 5％.Recent advances in diagnostic methods and therapeutic approaches have increased the possibility of improving the existing poorprognosis.Recently,compounds from naturalsources receive ample attention as anti-cancer agents.Overwhelming in vitro evidence and clinical trials suggest that curcuminn,isothiocyanate,capsaicin,catechin may reduce the incidence of cancer.

AIM: To observe the therapy effect of standard prescription on ametrop amblyopia in hyperopic children.
METHODS: This study included 270 cases ( 54 eyes ) with complete data, and followed up 24mo. All the amblyopic children were given standard prescription and were divided into progressive addition glass group, under corrected group and full corrected group. And all were observed for their therapy effect and the average healing time in low hyperopic, moderate hyperopic and high hyperopic children with ametropic amblyopia respectively.
RESULTS: In low hyperopic children, the difference of the therapy effect of the three corrected methods were insignificant in two years. The meam cure time of the three corrected methods were ( 7. 33 ± 2. 11 ) mo in progressive addition glass group;(9. 0±3. 71)mo in under corrected grope;(12. 5±5. 17) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=1. 66, P>0. 05) was statistically insignificant; the difference between progressive addition glass group and full corrected grope ( t = 3. 92, P < 0. 01 ) was statistically significant; the difference between under corrected grope and full corrected grope ( t = 2. 33, P < 0. 05 ) was statistically significant. In moderate hyperopic chileren, the differences of the therapy effect of the three corrected methods were significant in two years (χ2=6. 75;P<0. 05). The difference between progressive addition glass group and under corrected grope (χ2 = 6. 3; P < 0. 01 ) was statistically significant; the difference between progressive addition glass group and full corrected grope (χ2=8. 1;P<0. 005) was statistically significant. The mean cure time of the three corrected methods were ( 14. 0±4-87) mo in progressive addition glass group; ( 16. 93±4-58)mo in under corrected grope; (17. 93±4. 42) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=2. 88, P<0. 01) was statistically significant; the difference between progressive addition glass group and full corrected grope ( t= 3. 9, P<0. 01 ) was statistically significant;the difference between under corrected grope and full corrected grope ( t = 1. 01, P > 0. 05 ) was statistically insignificant. In high hyperopic amblyopic children, the difference of the therapy effect and the healing time of the three corrected methods were insignificant in two years. (χ2=2. 43, P>0. 05. t=1. 49, P>0. 05;t=1. 46,P>0. 05;t=1. 11, P>0. 05).
CONCLUSION:Under standard prescription, application of progressive multifocal glasses provides a new effective treatment for ametropic amblyopia in hyperopic children, and makes up the deficiency of the whole straightening and under correction in clinical treatment.

Objective: To investigate the relation between proliferation, apoptosis and Bcl-2 in human tongue squamous cell carcinoma(TSCC). Methods: Apoptosis, prolifexation and Bcl-2 protein expression were examined in 7 cases of normal tongue mucosa, 20(10 of Han and 10 of Uygur people) of tongue squamous cell papilloma (TSCP) and 42 of TSCC (30 of well-differentiated and 12 of middle-differentiated ) with immunohistochemical and in situ cell death detection technique. Results: The apoptosis index (TI) and the proliferation index (PI) showed no significant difference between Han and Uygur people or between male and femae, TI and PI in human TSCP were heigher than those in normal tongue mucosa, The proliferation was enhanced and apoptosis was inhibited according to dysplasia degree(P

OBJECTIVETo study the transferrable character of Acinetobacter baumannii (AB) plasmids with 3 types of beta-lactamase gene.

METHODSThe plasmid of multi-drug resistant AB (donor) isolated from burn wound were transferred to E. coil ATCC25922 (receptor) through conjugation, and drug sensitivity was also observed. Drug-resistant gene and stability of filial generation and zygote were analyzed by PCR.

RESULTSThe drug-resistance of donor plasmids to Sulfamethoxazole, Ampicillin, Cefalotin, Cefpodoxime, Cefuroxime, Imipenem/Cilastatin and Ampicillin/Sulbactam, and three types of beta-lactamase gene were transferred to the receptor, and were also stably transmitted for passages. The minimum inhibitor concentration of receptor to Sulfamethoxazole was > 2 mg/L after conjugation with donor, and inhibitory character could be transferred to next generation.

CONCLUSIONbla(TEM-1), bla(PER-1) and bla(OXA-23) genes carried in the plasmid of AB can be transferred through conjugation and stably transmitted for passages, and it is one of the molecular mechanisms for AB with multi-drug resistance after burn infections.
