Thalidomide has anti-tumor effects such as anti-tumor angiogenesis,improvement of immune function and cachexia of patients with advanced tumors,which has been effectively used in elderly patients with castration-resistant prostate cancer,chemotherapy resistant advanced colorectal cancer,advanced hepatocellular carcinoma and metastatic breast cancer.As the in-depth study of the anti-tumor mechanism of thalidomide, more and more clinical researches have focused on the function of thalidomide on non-hematological malignan-cies,especially it has obtained some achivements in the postoperative adjuvant therapy for high-risk colorectal cancer and primary hepatocellular carcinoma and the salvage therapy for metastatic triple-negative breast cancer and refractory gynecological tumor.

Objective To investigate the plantar pressure distribution of the injuried limbs and the healthy side after the operation for Pilon fracture. Methods 31 patients with Pilon fractures were tested with Footscan USB2 system, including the maximum force and impulse of 10 zones of the feet 1 year after surgery. Results Compared with the contralateral feet, the maximum force reduced under the the first metatarsal bone, medial heel, and lateral heel (P<0.05), and it increased under the fourth, and fifth metatarsal bone (P<0.05) of the injured feet. The impulse reduced under the the first metatarsal bone, medial heel, and lateral heel (P<0.05), and increased under the fifth metatarsal bone and midfoot (P<0.05). Conclusion The load decreased on the heel and medial forefoot, and increased on the lateral forefoot of the injured limbs after Pilon fracture, while the lateral forefoot and midfoot tend to be injured.

The potamon that were sold by Mengla market were examined positive for two species of paragonimus metacercariae andexcyted metac ercariae, this is the first report in Yunnan Province． The potamon that were sold by cities market from other suburbs may cause epdemic or outbreak of paragonimiasis, there is of momentous significance in epidemiology．

The sfa1 gene encoded a bifunctional enzyme with the activities of both alcohol dehydrogenase and glutathione-dependent formaldehyde dehydrogenase in Saccharomyces cerevisiae.The gene disruption cassette produced by PCR using the same long oligonucleotides which comprise 19 or 22 nucleotides complementary to sequences in the templates(pUG6 and pUG66 marker plasmid)at 3' end and 45 nucleotides at 5' end that annealed to sites upstream or downstream of the genomic target sequence to be deleted.After two linear disruption cassettes with a Cre/loxP mediated marker were transformed into the cells of Saccharomyces cerevisiae YS-1,the positive transformants were checked by PCR to correct the integration of the cassette and concurrent deletion of the chromosomal target sequence.Once correctly integrated into the genome,the select marker can be efficiently rescued by transformating the plasmid pSH47 into YS-1 and inducing the Cre expression with a Cre/loxP-mediated marker removal procedure.The expression of the Cre recombinase finally resulted in the removal of the marker gene,leaving behind a single loxP site at the chromosomal locus.The diploid mutant YS-1-sfa1 was generated,which could enhance the output of ethanol with 8.0% by shaking culture in flask compared with the original strain YS-1.

Background:Pulmonary arterial hypertension (PH) is a progressive disease with limited therapeutic options,ultimately leading to right heart failure and death.Recent findings indicate the role of the Warburg effect (aerobic glycolysis) in the development of PH.However,the effect of the glycolysis inhibitor 3-bromopyruvate (3-BrPA) on the pathogenesis of PH has not been well investigated.This study aimed to determine whether 3-BrPA inhibits PH and its possible mechanism.Methods:PH was induced in adult Sprague-Dawley rats by a single intraperitoneal injection of monocrotaline (MCT).3-BrPA,or phosphate-buffered saline (PBS) was administered via intraperitoneal injection every other day from the first day of MCT-injection to 4 weeks of follow-up,and indices such as right ventricular systolic pressure (RVSP),right ventricular hypertrophy index (RVHI),pulmonary arteriolar remodeling indicated by percent media thickness (％ MT),lactate levels and glucose consumption,were evaluated.Pulmonary arteriolar remodeling and right ventricular hypertrophy were observed in hematoxylin-eosin-stained lung sections.Western blotting,immunohistochemistry,and/or immunofluorescence analyses were used to measure the expression of relevant proteins.A cytochrome C release apoptosis assay and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling staining were used to measure cell apoptosis.Results:MCT-induced PH showed a significant increase in glucose consumption (0 vs.4 weeks:0.87 ± 0.23 vs.2.94 ± 0.47,P =0.0042) and lactate production (0 vs.4 weeks:4.19 ± 0.34 vs.8.06 ± 0.67,P =0.0004).Treatment with 3-BrPA resulted in a concomitant reduction in glucose consumption (1.10 ± 0.35 vs.3.25 ± 0.47,P =0.0063),lactate production (5.09 ± 0.55 vs.8.06 ± 0.67,P =0.0065),MCT-induced increase in RVSP (39.70 ± 2.94 vs.58.85 ± 2.32,P =0.0004),pulmonary vascular remodeling (％ MT,43.45％±1.41％ vs.63.66％±1.78％,P＜0.0001),and right ventricular hypertrophy (RVHI,38.57％ ± 2.69％ vs.62.61％ ± 1.57％,P ＜ 0.0001) when compared with those of the PBS-treated group.3-BrPA,a hexokinase 2 inhibitor,exerted its beneficial effect on PH by decreasing aerobic glycolysis and was also associated with inhibiting the expression of glucose transporter protein-1,inducing apoptosis,and suppressing inflammation.Conclusions:3-BrPA might have a potential beneficial effect on the PH treatment.

Objective To know about recent experience of the quality control of blood clotting,to analyze the reasons for its out-of-control,and then to explore the influencing factors of coagulation tests.Methods According to the testing standards of coagula-tion quality control products of Clinical Laboratory Center,Ministry of Health,each batch of products were taken standardized tests.The external quality control results of blood clotting from 2009 to 2013 were analyzed and counted up combined with the in-ternal quality control and daily work performance.Results The overall performance of external quality control was good (from 2009 to 2013).The total scores in 2009 were 90%,95%,were 100% and 100% in 2010,were 95% and 95% in 2011,were 100%and 85% in 2012,and were 100% and 100% in 2013.Conclusion Laboratory internal quality control should be guaranteed.The quality control of pre-analysis,post and analysis and analysis-in-course can improve clinical coagulation testing quality.

Objective To study three-dimensional reconstruction system (IQQA-Liver) in evaluation of resection volume and margin of hepatocellular carcinoma.Method Data of 51 hepatocellular carcinoma patients undergoing hepatectomy from March 2014 to October 2015 were analyzed retrospectively.All patients received preoperative ultrasound and CT/MIR evaluation.Three-dimensional reconstruction system (IQQA-Liver) was used to reconstruct tumor shape and location,the relationship between tumor and adjacent vessels or bile ducts.Then liver volume,liver resection volume,residual liver volume and surgical margin were calculated and compared with the actual resection liver values and actual margin.Results Images of three-dimensional reconstruction system (IQQA-Liver) were accurate,clear and directly perceived.In terms of the resection liver volume and resection margin,there was no significant difference between the predicted results and actual results [resection liver volume:(412.93 ± 471.26)cm3 vs.(487.02±529.01)cm3,t=0.75,P=0.46,resection margin:(13.72 ± 4.58) mm vs.(13.92 ±4.21)mm,t =0.23,P =0.82].The predicted resection liver volume was significantly correlated with the actual resection volume (r =0.91,P ＜ 0.01),the predicted resection margin was also correlated with the actual resection margin (r =0.89,P ＜ 0.01).Conclusion Three-dimensional reconstruction system (IQQALivcr) could accurately assess the resection volumc and margin of hepatocellular carcinoma.
