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.

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.

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.

OBJECTIVETo compare the differences in the therapeutic effect on irritable bowel syndrome (IBS) between acupuncture at Tianshu (ST 25) and Dachangshu (BL 25) and western medication with Trimebutine Maleate.
METHODSForty cases were divided randomly into an acupuncture group and a western medication group, 20 cases in each one. In acupuncture group, acupuncture was applied to Tianshu (ST 25) and Dachangshu (BL 25). Ziwu Daojiu needling technique was adopted, once daily. In western medication group, Trimebutine Maleate capsule was administered, 2 capsules in each time, 3 times per day. The assessment on the therapeutic effect was performed in 4 weeks of treatment in two groups.
RESULTSAs compared with those before treatment, the time of abdominal pain, the frequency of abdominal pain, the morbidity of abnormal stool appearance, the morbidity of defecation abnormality, the morbidity of mucus stool and the score of bloating or abdominal pain on bowel movement were all reduced after treatment in two groups (all P < 0.01). The results in acupuncture group were much more significant than those in western medication group (the total score: 16.70 +/- 2.40 vs 15.70 +/- 3.01, P < 0.01). The total effective rate in acupuncture group was 95.0% (19/20), which was superior to that of 70.0% (14/20) in western medication group (P < 0.05).
CONCLUSIONAcupuncture at Tianshu (ST 25) and Dachangshu (BL 25) may remarkably relieve the clinical symptoms of IBS and its efficacy is superior to that of oral medication with Trimebutine Maleate.

Objective To investigate the factors related to death of thoracic trauma emergency in children.Methods Total 528 children and infants aged 0-14 years with thoracic injuries , including 317 boys and 211 girls, admitted in emergency department from January 2010 to January 2014 were included in the study.The factors related to emergency death were investigated by using conditional logistic analysis.Results Among 528 cases, emergency death occurred in 34 cases with an emergency mortality rate of 6.44%.Single-factor analysis showed that emergency death was correlated with complication with other organ trauma, the time of first medical intervention , the time of arriving at first contact hospital , the rank of first contact hospital , hypoxemia and causes of injuries ( all P<0.05 ); however , not correlated with the gender, age, of patients, areas of residence, family economic status and seasons of injury occurring (all P>0.05).Logistic analysis showed that the time of first medical interventio n>30 min ( B=1.467,95%CI:0.412-0.975), complication with other organ trauma (B=2.342,95%CI:0.415-0.943), hypoxemia (B=2.915,95%CI:0.749-0.819), and first visiting to tertiary hospital (B=-1.861,95%CI:1.023-1.742) were influencing factors of emergency death.Conclusion The results indicate that to improve the success rate of emergency treatment of thoracic trauma in children , it is necessary to reduce the time of first medical intervention and to correct the hypoxemia promptly.
