Sixty four patients undergoing endoscopic sinus surgery were randomly divided into two groups.In nimesulide group (n=32) patients were given nimesulide capsule 100 mg after surgery and 32 patients in control group were given 100 mg vitamin C as placebo.The visual analogue scale (VAS) was used to evaluate the degree of pain during withdrawing nasal packing.The VAS value of the nimesulide group was 2.8±1.1 3 h after surgery and 2.7±1.2 during with drawing nasal packing,that of control group was 6.7±0.6 and 8.3±0.6,respectively (both P<0.01).The results revealed that nimesulide had a siguificant analgesic effect in endoscopic sinus surgery.

Objective To explore the possibility of non-discarding blood after cisplatin hyperther-mic antiblastic perfusion(HAP)in treating the patients with malignant bone tumor of lower extremity.Methods Forty patients consisted of 31osteosarcomas and9malignant fibrous histiocytomas of bone.The clinical stages were wholly classified intoⅡB stage according to Ennekings surgical staging system for muscu-loskeletal tumors.The patients were divided into three groups:group1:discarding blood group(10cases),in whom200ml of the400ml blood remaining in heart-lung machine was discarded after HAP;group2:Non-discarding blood group(25cases),the blood remaining in heart-lung machine was not discarded after HAP and re-infused into systemic circulation;group3:systemic chemotherapy group(5cases),cisplatin was infused intravenously.The regional and the systemic blood cisplatin concentrations were determined at3,30and60minutes during HAP,and the systemic blood cisplatin concentrations were determined at0,0.5,1,2,4,8,12,24,48and72hours after HAP in the group1and group2.While1h after cisplatin infusion in-tra venously in the group3,the blood cisplatin concentration were also measured.Results The regional blood cis platin concen tra tions were high er than that in systemic blood at the time during HAP.The systemic blood cisplatin concen trations after HAP,ex cept at0minute in the group2were higher than that in the group1,there were sig nificant statistic differences between the two groups.The systemic blood cisplatin con-cen trations after HAP in the group2were simi lar to that after systemic chemotherapy.No severe adverse ef-fects in the group1were found.The Ennek ings surgical stagings for the tumors were turned fromⅡB intoⅡA in all the patients.Conclusion The method of non-discarding blood after HAP is available,it is not only local treatment ,but also systemic chemotherapy in the patients with malignant bone tumor of lower ex-tremi ty for limb-salvage surgery.

Objective To investigate the efficacy of intracoronary tirofiban during percutaneous coronary intervention(PCI)for patients with acute myocardial infarction(AMI).Methods Seventy-six consecutive AMI patients,treated with primary coronary angioplasty in 12 hours were enrolled.They were randomly divided into two groups:tirofiban group(39 cases)and control group(37 cases).Tirofiban group was treated with intracoronary timfiban during PCI and after the operation for 48 hours.Both of them were given heparin in PCI and aspirin,clopidogrel before PCI.At the end of PCI procedure,angiographic features such as TIMI flow grade and TIMI myocardial perfusion grade(TMPG)were analyzed.The difference of two groups in complication and major adverse cardiac events(MACE) was investigated.Results The myocardial reperfusion of tirofiban group was better than that of control group[TIMI grade 3 flow 94.9%(37/39) vs 78.4%(29/37),P<0.05;TMPG 3 grade 89.7%(35/39)vs 67.6%(25/37),P<0.05].There was no significant difference between two groups in bleeding complication.The occurrence of MACE in tirofiban group was less than that in control group[7.7%(3/39)vs 18.9%(7/37),P<0.05].Conclusion Intracoronary tirofiban dunng primary PCI in patients with AMI can improve coronary flow and myocardial perfusion,and has no more bleeding and less MACE occurrence.

?Advances in genome-wide analysis have revealed that up to 90%of the human genome is transcribed.However, only approximately 1% of RNA transcripts encode proteins, and the remaining transcripts are noncoding RNAs.Noncoding RNAs can be roughly divided into small noncoding RNAs (<200nt ) and long noncoding RNAs ( LncRNAs, >200nt ). Small noncoding RNAs include microRNAs, transfer RNAs and small nucleolar RNAs, whereas the long noncoding RNAs comprise ribosomal RNA, natural antisense transcripts, etc. Although the biosynthesis and biological activities of microRNAs are well studied through bioinformatics and active biological molecules analysis, the understanding of LncRNAs on these aspects is still limited.LncRNAs play multiple roles in regulating gene transcription and translation, and epigenetics.Aberrant LncRNAs expression can occur in various pathological processes and significantly related to the pathogenesis or poor prognosis of ophthalmological diseases. In this review, we will focus on the characteristics and regulatory functions of LncRNAs that are commonly associated with ophthalmological diseases.

Objective To analyze the electroencephalograph (EEG) features of 43 patients with clinically possible or probable Creutzfeldt-Jakob disease (CJD) and its correlation with megnetic resonance imaging (MRI) imaging and clinical manifestations.Methods All patients diagnosed with suspected CJD who were hospitalized in Xuanwu Hospital from January 2013 to December 2015 were collected.The clinical data, EEG and MRI imaging features were analyzed retrospectively.Based on the periodic sharp wave complexes (PSWC) appearance in EEG results, the patients were divided into typically changed group (TCG), atypically changed group (ACG) and unchanged group (UCG).Age, disease duration, clinical manifestations and MRI features among three groups were analyzed and the correlations between patient′s EEG features and age, disease duration, clinical manifestations or MRI features were explored using spearman method.Results Among the 43 patients with possible or probable CJD disease, 26 were male and 17 were female with an average disease duration of 4 months.The age of onset ranged from 31 to 80 with an average of (58.0±9.8) years old, and 86.0% of patients were 51 years old or above.Clinical characteristics of CJD patients according to occurrence rate were as follows: 35 cases (81.4%) with cognitive impairment, 29 cases (67.4%) with mental and behavior disorder, 28 cases (65.1%) with pyramidal tract damage, 24 cases (55.8%) with cerebellar symptoms, 23 cases (53.5%) with extrapyramidal symptoms,17 cases (39.5%) with myoclonic, 13 cases (30.2%) with dyssomnia, 13 cases (30.2%) with visual disorder and 2 cases (4.7%) with akinetic mutism.Regarding EEG features, 39.53% (17/43) of patients showed typical periodic sharp wave complexes (PSWC) (TCG group), 51.2% (22/43) had irregular rhythm and different forms of slow wave (ACG group) and only 9.3% (4/43) had no EEG change (UCG group).The occurrence rate of ribbon sign in MRI was 82.4% (14/17) in TCG group, 77.3% (17/22) in ACG group and none in UCG group.The rates were significantly higher in TCG and ACG group than that in UCG group (both P<0.05).Spearman correlation analysis revealed that EEG features was correlated with disease duration (r=0.351, P=0.021) and visual impairment (r=-0.377, P=0.013) for all CJD patients.There was no correlation between EEG and MRI or other clinical manifestations such as myoclonic, age and so on (all P>0.05).Conclusions EEG showed typical changes associated with disease duration in different stages of disease.EEG and MRI are two different means to evaluate different aspects of patients with CJD disease, and combination of two means could achieve better evaluation results.

The excipient processing is an essential part of traditional Chinese medicine processing, and understanding its scientific connotations is a critical scientific issue that urgently needs resolution. Building upon a foundation where the composition of traditional Chinese medicine substances is fundamentally clear, this paper applies the techniques and methods of chemoinformatics to the study of the excipient processing mechanism. Relevant information on traditional Chinese medicines processed with four kinds of excipients (wine, vinegar, salt and honey) was collected, including properties, taste, meridian tropism, chemical components, etc. Molecular descritors and skeletons corresponding to each chemical component were calculated using chemoinformatics to characterize the properties and structural features of the components. Characteristic components associated with the four excipients (wine, vinegar, salt and honey) were explored through multivariate statistical analysis and Murcko skeleton analysis. Further analysis, taking honey-processed Astragali Radix as an example, the focus was on the impact of the processing excipient honey on the solubility and permeability of its characteristic pharmacologically active components (isoflavones). It was discovered that the excipient honey can increase their solubility and permeability, emphasizing that the impact of processing excipients on the pharmacological classification properties is a key breakthrough in elucidating the mechanism of excipient processing. In summary, this study analyzed the characteristic components associated with the processing excipients "wine, vinegar, salt and honey" based on their composition characteristics, providing data support for the research on the mechanism of excipient processing from a biopharmaceutical perspective.

Objective · To investigate the possible factors affecting the gastric emptying rate in patients with type 2 diabetes mellitus. Methods · 94 type 2 diabetic patients treated at the Department of Endocrinology of Renji Hospital affiliated toShanghai Jiao Tong University School of Medicine from September 2013 to March 2014 were enrolled. The half gastric emptying time (T1/2) and retention at 120 min (R120 min) were measured.Results · Female patients had longer T1/2 (P=0.000) and higher R120 min (P=0.000) than male patients. The differences in age, duration of iabetes,BMI, blood glucose level, chronic diabetic complications, and gastrointestinal symptoms between normal and delayed gastric emptying groups were not statistically significant. Acarbose had no effect on the gastric emptying rate in type 2 diabeticpatients. Conclusion · The gastric emptying rate in type 2 diabetic patients is associated with the gender and has no significant correlation with blood glucose level, chronic diabetic complications, gastrointestinal symptoms, and acarbose.

ObjectiveTo evaluate the inter-and intra-fractional clinical target volume (CTV) positioning errors of patients receiving postoperative simplified intensity-modulated radiotherapy (SIMRT) using cone beam computed tomography (CBCT).MethodsTwelve patients with liver tumors underwent postoperative SIMRT.CBCT images were acquired before and after the treatment.The clipbox volume for registration included the fiducial markers in the tumor bed and excluded the ribs and vertebral bodies.If any translational parameter of setup error before treatment exceeded 3 mm or rotational parameter exceeded 3°,the treatment couch was adjusted and a verification CBCT was acquired to assess residual setup error.Automatic bone match was used.A total of 214 acquisitions of CBCTs in 111 groups were analyzed.Inter-fractional translational CTV positioning errors in left-right (x),superior-inferior (y) and anterior-posterior (z) axis were calculated in 111 groups,and intra-fractional translational CTV positioning errors in 70 groups.Clinical to planning target volume (PTV) margins were calculated according to the formula:margin =2.0 ∑ + 0.7σ ( ∑ is systematic error,σ is random error).ResultsInter-fractional translational CTV positioning errors in x,y and z axis were -0.03 mm,-0.43 mm,1.02 mm,with systematic error ( ∑ ) of 1.50 mm,5.89 mm,1.97 mm,and random error (σ) of 1.76 mm,4.13 mm,2.42 mm,respectively.Intra-fractional translational CTV positioning errors in the x,y,z axis were 0.04 mm,0.86 mm,- 0.46mm,with systematic error (∑) of 0.46 mm,1.14 mm,0.31 mm,and random error (σ) of 0.95 mm,1.38 mm,0.91 mm,respectively.The calculate CTV to PTV margins were 4.5 mm,15.0 mm,5.8 mm in the x,y,z axis,respectively.ConclusionsThe CTV errors were inevitable when patients with liver tumors received SIMRT.Fiducial markers placed in tumor bed during operation were helpful for accurate positioning error analysis.

Aimed at feasibility of microbiological control of Chironomidae larvae in sourcewater, Shenzhen, China, the functional characters of Bacillus thuringiensis subsp. Iaraelensis to Chironomus kiiensis tokunaga were studied for the first time. In this study, bioassays were carried out with third-instar larvae, results showed that the LC 50 s(24h) were 24.2 and 32.6 mg/L for Bacillus thuringiensis subsp. Iaraelensis IPS82 and 187 respectively. Tests in fermentation of IPS82 show good correlations between toxicity, cell density, dissolved oxygen and spore-forming phase. The tests on environmental factors influencing toxicity to Chironomus kiiensis tokunaga showed that sunlight is the most important factor, shortening the half life of Bti from 21 days in dark to 10 days; temperature variations(15～30℃) caused no impact on toxicity, but 35℃ increases 16% of larvae mortality. The toxicity of IPS82 is relatively insensitive to change pH deviated from 7 to 11, due to drop of larvae mortality from 66.7 to 40%, at pH of 3, to 16%; its toxicity is stable in low larva density (

Objective To improve the prognosis and radical resection of the extended pancreaticoduodenectomy for patients with pancreatic cancer in the ucinate process involving mesentery mot. Methods From Jan. 2004 to Dec. 2007, a total of 23 ( 14 male and 9 female, aged between 30 and 72 years old) patients with pancreatic cancer in the ucinate process involving mesentery root were treated in our department. Curative resection was performed for all patients by the extended pancreaticoduodenectomy with superior mesenteric artery (SMA) isolation and mesentery root resection. The surgical procedure, the safety and prognosis were analyzed retrospectively. Results 12 patients underwent the procedure, among them 11 also underwent combined SMV partial resection and reconstruction. The operation time was (4.2 ± 1.1 ) hours, and the blood loss was ( 1 635 ± 1 362) ml with the blood transfusion of ( 1 609 ± 1 462 ) ml. There was no operation related death in this case series, and mild to severe diarrhea occurred in 6 cases. The post-operative stay ranged 9 to 30 days. The pathological examination showed that the tumor size was (5.3 ± 1.4) cm. 13 patients (57%) had one or more lymph nodes metastasis. 20 patients (87%) had nerve involvement. Among 11 patients with SMV partial resection and reconstruction, 10 patients had endangium involvement. 22 patients had negative surgical margins for all specimens. Rapid intra-operative frozen pathological examination showed negative surgical margins in one patient, however, post-operative paraffin section pathological examination revealed nerve involvement between SMA and celiac trunk. After a follow-up of 5 to 42 months, liver metastasis occurred in 4 patients, and local recurrence occurred in 3 patients. The 1-year and 2-year accumulated survival rates were 77.2% and 42.5%, respectively. Conclusions Isolation SMA and the mesentery resection in extended pancreaticodudenectomy were safe and useful. Using this modified technique, Radical operation resection could be achieved in the treatment of pancreatic cancer in uncinate process.
