AIM: To evaluate the use of 23G minimally invasive vitreous cutting system in the first stage of anterior segment reconstruction on severe ocular injury.
METHODS: Fifteen patients with ocular injuries including the corneal and scleral rupture associated hyphema, vitreous hernia in anterior chamber, traumatic lens rupture, lens subluxation, applied 23G minimally invasive vitreous cutting system in the first stage of anterior segment reconstruction.
RESULTS: The anterior ocular media of early postoperative became transparent quickly. No exudative lemma and no complications were found relate to puncture incisions after operations.
CONCLUSION:23G minimally invasive vitreous cutting system can be used in the first stage of anterior segment reconstruction on sever ocular injury. It can reduce iatrogenic injury, operative complications and inflammatory response, also can shorten therapeutic time and create favorable conditions.

The premembrane and envelope proteins (prM-E),which contains the mainly protective antigen related with virulence and tropism,are the primary structural protein of flavivirus.However,prM-E in ZIKV is rarely understood.We have analyzed the structure and biological effects of prM-E in ZIKV by bionformatics methods.The prM-E proteins virus-like particles of dengue virus was introduced in the present.Then,the prM-E proteins virus like particles of ZIKV was prospected.

Objective To explore an algorithm to define the threshold value for tumor contouring on 18F-fluorodexyglucose (FDG) PET imaging. Methods A National Electrical Manufacturing Association (NEMA)NU 2 1994 PET phantom with 5 spheres of different diameters were filled with 18F-FDG. Seven different sphere-to-background ratios were obtained and the phantom was scanned by Discovery LS 4. For each sphere-to-background ratio, the maximum standardized uptake value ( SUVmax ) of each sphere, the SUV of the border of each sphere ( SUVborder ), the mean SUV of a 1 cm region of background (SUVbg) and the diameter (D) of each sphere were measured. SPSS 13.0 software was used for curve fitting and regression analysis to obtain the threshold algorithm. The calculated thresholds were applied to delineate 29 pathologically confirmed lung cancer lesions on PET images and the obtained volumes were compared with the volumes contoured on CT images in lung window. Results The algorithm for defining contour threshold is TH% = 33.1% + 46.8% SUVbg/SUVmax + 13.9%/D ( r = 0.994) by phantom studies. For 29 lung cancer lesions, the average gross tumor volumes ( GTV ) delineated on PET and CT are ( 7.36 ± 1.62 ) ml and (8.31 ±2.05) ml, respectively (t = -1.26, P＞0.05). Conclusion The proposed threshold algorithm for tumor contouring on PET image could provide comparable GTV with CT.

ING1 family is a candidate for tumor suppressor,which has three splicing isoforms named p47ING1a,p33ING1b,and p24ING1c. Study of the effect of different isoforms of ING1 on HeLa cells proliferation and its molecular mechanism would help further identifying the functional relationship of ING1 isoforms,and finding important genes regulated by ING1. Cell growth curve and cell cycle analysis were used to observe the effect of ING1a,ING1b,and ING1c on HeLa cells growth,and the result indicated that they could all inhibit HeLa cells growth by arresting cell cycle at G0/G1 phase. PCR method was used to construct the PHD domain deletions of ING1a and ING1b. ING1a,ING1b,ING1c and the PHD domain deletions 1a?C and 1b?C were then overexpressed in HeLa cells. p16INK4a,PTEN/p27Kip1 and p53/p21Waf1 protein levels were detected by Western blot. The result showed that ING1a,ING1b,ING1c,and 1a?C except for 1b?C induced p16INK4a protein expression,in which ING1c had the most powerful effect. Luciferase assay identified that overexpression of pcDNA3.1(+)-1a?C facilitated p16INK4a transcription through enhancing p16INK4a promoter activity,while pcDNA3.1(+)-1b?C repressed the p16INK4a promoter activity . In a word,it was found for the first time that except for the p53/p21Waf1 pathway,three splicing isoforms of ING1 family could also inhibit HeLa cells proliferation though upregulation of p16INK4a and PTEN,and the PHD domain deletion of ING1a enhanced p16INK4a transcription. These findings provide new clews to further study on the mechanisms of ING1 family suppressing cancer cells growth.

Objective:To study the effect of different doses of oxycodone on the serum thromboxane A2 (TXA2),plasma endothelin (ET) levels and immune function of patients underwent laparoscopic cholecystectomy.Methods:90 patients of elective laparoscopic cholecystectomy who were treated from August 2013 to August 2016 in our hospital were selected and divided into 3 groups by random number table,with 30 cases in each group.At the beginning of operation,they were given intravenous oxycodone,group A was given 0.1 mg/kg oxycodone,group B was given 0.2 mg/kg oxycodone,group C was given 0.3 mg/kg oxycodone.The changes of hemodynamics,serum TXA2 and ET levels were compared between the three groups at T0 (after admission),T1 (after anesthesia induction),T2 (after intubation),T3 (gallbladder separation),T4 (end of surgery) and the changes of immune function was compared at T0,T5 (postoperative 2h),T6(postoperative 1d),T7 (postoperative 3d);and the extubation time,recovery time,hypotensor,additional analgesics situationin and adverse reactions were recorded.Results:The diastolic pressure (DBP),systolic blood pressure (SBP),heart rate (HR) in three groups at T2,T3 point was significantly higher than T0 point(P＜0.05),the DBP,SBP and HR in the B,C groups were significantly lower than the A group at T2 and T3 point(P＜0.05);the TXA2 in three groups at T2,T3,T4 point was significantly higher than T0 point(P＜0.05),and A group＞B group＞C group,there was significant difference between the two groups (P＜0.05);the ET in three groups at T2,T3 point was significantly higher than T0 point(P＜0.05),the ET in the B,C group was significantly higher than the A group at T2,T3 point(P＜ 0.05);the CD3+,CD4+,CD8+ and CD4+/CD8+ of the three groups at T5 point were significantly lower than that ofT0 point (P＜0.05),the CD3+,CD4+,CD8+ and CD4+/CD8+ in A group were significantly lower than that of B,C group at T5 point (P＜0.05);the extubation time in C group was significantly longer than that of A,B group(P＜0.05);the total incidence of adverse reactions in C group was significantly higher than that the A,B group (P＜0.05).Conclusion:In the laparoscopic cholecystectomy,application of 0.2 mg/kg oxycodone had little effect on hemodynamics,serum TXA2,ET levels and immune function with higher safety.
