Objective To observe the predictive value of Alberta stroke program early CT score (ASPECTS) and hemorrhage after thrombolysis score (HAT score) for the hemorrhagic transformation (HT) of acute cerebral infarction (ACI) patients after thrombolysis with Alteplase.Methods One hundred and twenty-one patients with ACI admitted to the Department of Neurology of Tianjin Jinghai District Hospital from January 2015to March 2017 were enrolled, they were all treated by using Alteplase 0.6 mg/kg for thrombolysis, maximum dose being 90 mg, and 1/10 of the total dose was intravenously injected in 1 minute, and then the residual part dissolved in 100 mL normal saline was intravenously dripped continuously for 1 hour. The ASPECTS and HAT score were carried out before the start of thrombolysis, and then the HT incidence situations in patients with different ASPECTSs and HAT scores were compared, and logistic regression analysis was used to analyze the risk factors of HT after thrombolysis in patients with ACI; then the receiver operating characteristic (ROC) curve was drawn, and the clinical value of HAT score and ASPECTS in diagnosing HT occurrence was analyzed.Results In cases with ACI, it was discovered that the higher the ASPECTS, the lower the incidence of HT, indicating that the incidences of HT in patients with ASPECTSs 0-4, 5-7, 8-10 were 57.1% (4/7), 26.7% (8/30), 14.3% (12/84) respectively; Similarly, in such cases, the higher the HAT scores, the higher the incidence of HT, showing that the incidences of HT of patients with HAT scores 0, 1, 2, ≥ 3 were 7.1% (4/56), 21.0% (8/38), 33.3% (7/21), 83.3% (5/6) respectively. The single factor analysis showed that the risk factors influencing the HT incidence included the systolic blood pressure on admission, anti-platelet medicine taken in the past history, the sign of high density of middle cerebral artery shown in head CT film on admission, the time of interval between the onset of the disease and the beginning of thrombolysis, HAT store and ASPECTS [odds ratio (OR) values were 0.972, 0.279, 0.992, 0.311, 2.628, 2.625, respectively, 95% confidence intervals (95%CI) were 0.9352-1.012, 0.093-0.836, 0.983-1.000, 0.105-0.916, 1.362-5.071, 1.522-4.525,P values were 0.034, 0.023, 0.042, 0.034, 0.003, 0.045 respectively]; the multifactorial logistic regression analysis showed that the independent risk factors influencing HT incidence were as follows: the systolic blood pressure on admission, anti-platelet medicines taken in the past history, the sign of high density of the middle cerebral artery shown in the head CT film on admission, the time of interval between the onset of the disease and the beginning of thrombolysis, HAT score and ASPECTS (OR values were 1.766, 1.012, 1.574, 1.030, 2.155, 2.431, 95%CI were 1.233-2.103, 1.009-1.204, 1.186-2.091, 1.009-1.053, 1.237-4.907, 1.213-5.815,P values were 0.023, 0.004, 0.002, 0.005, 0.007, 0.047); HAT score and ASPECTS could predict the risk of HT incidence after venous thrombolytic therapy, sensitivity, specificity, area under ROC curve (AUC), 95%CI in ASPECTS were higher than thoes of HAT score (94.4% vs. 94.0%, 61.4 vs. 41.0%, 0.77 vs. 0.70, 0.710-0.830 vs. 0.650-0.800).Conclusions It is shown in this study that the higher the ASPECTS, the lower the incidence of HT, and the higher the HAT score, the higher the incidence of HT; both HAT score and ASPECTS can predict the risk of HT incidence after venous thrombolytic therapy, and the predictive value of ASPECTS system is higher than that of HAT score.

Objective To investigate the causes of non-union and delayed union of fractures and to report the surgical techniques and outcomes of the treatments. Methods 107 cases of non-union, 54 cases of delayed union and 2 cases of congenital non-union of tibia were treated between July 1990 and December 2004 in our hospital. The treatments were evaluated retrospectively to analyze the causes of the disorder and the treatment outcomes at the follow-up. 18 cases of delayed union were treated conservatively while the other 145 cases in this series underwent surgery. Results Except in the 2 cases of congenital non-union of tibia, iatrogenic factors were found to be responsible for nonunion or delayed union in all the other 161 cases. 153 cases were followed up for an average of 17 (6 to 28) months only to reveal bone union in all the cases with a mean healing time of 10 (6 to 14) months. All the limbs regained good function. Conclusion Since development of non-union and delayed union of fractures chiefly result from iatrogenic technical defects, satisfactory results can be achieved as long as appropriate treatments are performed according to different etiological factors.

n -3 polyunsaturated fatty acids (n -3 PUFAs),essential fatty acids for human body,have varied biological activities.They are absolutely or relatively deficient in modern human diets.Supplementation of n -3 PUFAs in early life is important for the optimal growth and development in fetus,infants and children,and well as for prevention of chronic non -communicable diseases in later life,such as attention deficient hyperactivity disorder,allergic diseases, asthma,hyperlipidemia and non -alcoholic fatty liver disease.The human body can synthesize eicosapentaenoic acid (EPA)and docosahexaenoic acid (DHA)with linolenic acid,but the ability is limited.Therefore,intake of pre -formed EPA and DHA is needed for body requirement.For pregnant women and infants,supplementation of DHA and EPA with a ratio above 51 is suggested.In clinic,n -3 PUFAs have been applied for treatment of chronic non -com-municable diseases and proved to be beneficial in relief of symptoms.

Objective　To evaluate the efficacy and safty of pegging hydroxyapatite orbital implants.Methods　Fourty-five patients who received drilling and pegging of hydroxyapatite orbital implants were studied retrospectively, and all patients used the peg and sleeve system followed-up 2 to 24 months.Results　The rate of success of the first operations is 82.2%. Complications associated with pegging included peg hole drilled on an angle, drilling off-center, drilled hole shallow, granuloma and infection, total complications occured in 22.2% in the review, most that are of a minor nature can be cured.Conclusions　The hydroxyapatite orbital implants can be directly coupled to the prosthesis through a peg system, allowing a wide range of prosthesis movement and giving a more lifelike quality to the prosthesis. When and how to drill and exactly hole on implant is the key for pegging.

ObjectiveTo observe the therapeutic effect of standing bed on orthostatic hypotension with cervical spinal cord injury. Methods36 patients with cervical spinal cord injury were divided randomly into the standing bed group and routine treatment group. The blood pressure of all patients were measured every day during rehabilitation treatment. The function of spinal cord was assessed before and after treatment.ResultsThe function of sensory and motor in the two groups were all improved, but there was no statistical difference between the two groups in the grades of spinal cord function. There were 27 patients who had orthostatic hypotension in the study. All the patients with complete spinal cord injury suffered the orthostatic hypotension. There was no improvement in blood pressure of complete spinal cord injury after treatment. In incomplete spinal cord injury patients, there was a significant improvement and the difference of blood presure between lying and standing was decreased in standing bed group after treatment (P<0.05). Compared with routine treatment group, the blood pressure in standing bed group was improved (P<0.05). Conclusions Cervical spinal cord injury could have orthostatic hypotension. Complete spinal cord injury would suffer orthostatic hypotension in different degree. The standing bed treatment could improve the orthostatic hypotension in incomplete spinal cord injury.

Objective To evaluate the effectiveness of a newly designed modular flexible ureteroscope with holmium laser lithotripsy for the treatment of renal calculi based. Methods 40 patients were treated with modular flexible ureteroscopic lithotripsy (German Polydiagnost) with holmium laser. 40 patients were treated by traditional flexible ureteroscopic lithotripsy. Their therapeutic effects were compared. Results For modular flexible ureteroscopic lithotripsy group, 37 patients underwent successful operation, with lithotripsy with operation time of (86.0 ± 34.4) min and postoperative hospital stay of (5.3 ± 1.6) days. No severe complication including ureteral perforation, high fever or severe bleeding occurred. One month after the operation, KUB and B-ultrasonography showed complete stone free in 35 patients. Residual calculi (0. 4 cm in diameter) in the calyces were found in 2 patients. Medication and postural drainage therapy were applied. Two weeks later , KUB and B-ultrasonography showed that the residual stones have been removed completely. There was no significant differences in stone size , operation time, rate of calculus clearance, the incidence of postoperative complications, operating time and duration of postoperative hospitalization between the traditional flexible ureteroscopic lithotripsy group and modular ureteroscopic lithotripsy group. Conclusions The modular flexible ureteroscope is effective and safe in treating reanl calculi. It has similar surgical efficacy as traditional flexible ureteroscope , but is more costly effective in terms of maintenance costs.

OBJECTIVETo perform a transcriptomics study in differential genes after Xianglian External Lotion (XEL) induced the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole.

METHODSBroth microdilution antifungal susceptibility test was used to detect minimal inhibitory concentration (MIC) of drug-resistant Candida albicans strains induced by XEL. Transcriptome sequencing (RNA-Seq) was used to determine and compare the transcription of primary drug-resistant Candida aIbicans strains and sensitive strains induced by XEL. High expressed genes and signaling pathways strains were analyzed by gene ontology (GO) method.

RESULTSXEL could induce drug-resistant strains of the 6th generations to recover sensitivity. Transcriptome sequencing showed that, as compared with primary drug-resistant strains, there were 165 genes with up-regulated RPKM index and 144 genes with down-regulated RPKM index after XEL induction. GO analyses found that all genes were mainly classified as GO:0015903 (fluconazole transport).

CONCLUSIONSXEL could induce the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole. By analyzing transcriptomes, authors speculated that XEL could recover strain sensitivity to fluconazole by opening fluconazole transport pathway.
