AIM:To study the changes of tear film and ocular surface after the coaxial micro incision 2. 2mm and 2. 8mm in the phacoemulsification.
METHODS:Eighty-six patients ( One hundred and six eyes ) from 2014/06 to 2016/01 in our hospital were enrolled. The patients were randomly divided into two groups. Forty-four patients ( Fifty-three eyes) in group A: coaxial 2. 2mm micro- incision phacoemulsification cataract extraction and intraocular lens(IOL) implantation;Forty-two patients ( Fifty-three eyes ) in group B: the conventional coaxial 2. 8mm small incision phacoemulsification cataract extraction and IOL implantation. The break up time ( BUT) , dry eye symptom ( DES) score, Schirmer's I test ( SⅠt ) and lid-wiper epitheliopathy ( LWE ) score were assessed preoperatively and postoperatively.
RESULTS:At 1wk, 1 and 2mo postoperatively, the BUT in two groups decreased after operations, and the BUT of group B was significantly lower than those of group A, the differences were statistically significant ( t = 3. 098, 4.512, 4.329; all P < 0. 05 ). The DES score in two groups increased, the DES score of group B was significantly higher than those of group A and the differences were statistically significant (t=-9. 449, -10. 029, -7. 141; all P<0. 05). The SⅠt in two groups increased after operations, the SⅠt of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 293, -4. 009, -3. 283; all P<0. 05). The LWE score in two groups increased after operations, the LWE score of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 542,-5. 125, -3. 632; all P<0. 05). At 6mo postoperatively, compared with the preoperative data, the BUT, DES score, S Ⅰ t and LWE score in group A showed no statistically significant differences (t=0. 659, 1. 276, 0. 548, 0.169; P>0. 05). The BUT, DES score, SⅠt and LWE score in group B showed statistically significant differences (t=-4. 063, 7. 306, 3. 621, 4. 208;all P<0. 05).CONCLUSION:Ocular surface has less damage and tear film has little influence at early stage after the coaxial 2.2mm microincision phacoemulsification, compared with the conventional coaxial 2. 8mm incision phacoemulsification surgery.

Objective To investigate the new epidemiology and clinical manifestation of measles in children in recent years. Methods One hundred and twenty-eight cases of children′s measles were collected,and their epidemiological and clinical characteristics of age distribution,endemic distribution,vaccination,clinical manifestation,complication and misdiagnosis were discussed. Results Among the patients living in urban,90% cases were single dose vaccination,35% cases were between 3-8 years old,27% cases were less than 8 months old,59% cases were mild measles,27% cases were atypical measles,40% cases were misdiagnosed at first visit,and 67% cases of measles less than 8 months old were babies of vaccine immunized mother.Among the patients living in rural,68% cases had no vaccination,86% cases were at age of typical onset,61% cases were typical measles,7% cases were severe measles,and 28% cases were mild measles.Among all cases of measles,mild measles and atypical measles were as high as 41% and 16%,but typical measles were only 37%.In all patients,56% cases had typical measles rash,82% cases had Koplik′s spots,77% cases had typical onset of eruption,100% cases had higher fever in eruption stage,89% cases had typical downward sequence of eruption,93% cases had skin pigmentation,and 81% cases had desquamation. Conclusions Less than 8 months infants and single dose vaccinated pre-school children are newly susceptible group of measles.Mild measles and atypical measles markedly increased,with atypical clinical symptoms,variable rash and variant onset,but the character of aggravated fever in eruption stage scarcely changes.Infants of vaccine immunized mother and pre-school children are advised to vaccinate ahead of schedule.

AIM:To observe the inhibition effect of endostatin ( endostar ) on mice choroidal neovascularization model ( CNV) and compare with the Avastin.
METHODS: Using 532nm laser photocoagulation to establish a mouse model of CNV. We observed the formation of CNV by histopathological examination after 2wk later. Forty successful models of mice were randomly divided into control group (group 1, 10 rats), normal saline group ( group 2, 10 rats ), endostatin group (group 3, 10 rats) and avastin group (group 4, 10 rats) . The drugs were injected into the mice' vitreous after photocoagulation 2wk later. Then 1wk later, we took the mice eyeballs to perform the HE and immunohistochemical staining to observe. The statistical analysis of ANOVA was done by SPSS 16. 0 and the LSD-t test was used for multiple samples, taking P<0. 05 as the test standards.
RESULTS: Two weeks later, HE histopathological examination was done , light microscope showed large amount of new vessels' formation, the positive rate for CNV was 72. 8%. The blank control group compared with the normal saline group P>0. 05, had no inhibitory effect on CNV;endostatin treated group compared with control group, P<0. 05, had a certain inhibitory effect; avastin group compared with the control group, P<0. 05, had an inhibitory effect on CNV; the LSD-t was performed on Avastin group and endostatin group, P<0. 05, which were statistically significant. We thought that the two drugs have different inhibitory effect on mice' CNV, because xAvastin=26. 90 ,xendostatin=29. 13,xAvastin CONCLUSION: Laser-induced CNV animal models of colored mice C57BL/6J is of short time and high rate establishment and it is an ideal model for CNV study. Endostar has certain inhibitory effect on CNV, and it is likely to become one of the important drugs for CNV-related diseases in the future.

Objective To assess the incidence,risk factors and mortality of acute kidney injury(AKI)in patients with chronic myelogeneous leukemia(CML)after myeloablative allogenetic hematopoietic stem cell transplantation(HSCT). Methods Renal function in 93 CML patients undergone myeloablative allo-HSCT was retrospectively analyzed by the RIFLE criteria. Results Thirty-nine patients (41.9%) developed AKI at a median of 40 days after allo-HSCT, including 24 AKI-R patients(25.8%), 10 AKI-I patients(10.8%) and 5 AKI-F patients (5.4%). The morbidity of AKI in patients with ≥Ⅲ acute graft-versus-host disease (aGVHD) and without ＜Ⅲ GVHD was (81.82±11.63)% and (36.59±5.32)% (P=0.0037)rospectively. The morbidity of AKI in patients with increased total bilirubin and without increased total bilirubin was (72.73±13.43)% and (37.04±5.37)%(P=0.0192) respectively. ≥Ⅲ aGVHD was peor-prognostic factor of AKI and RR was 2.773 [95%CI (1.073-7.167), P=0.035]. RR of AKI-I and AKI-F in patients with ≥Ⅲ aGVHD was 6.320195%CI (1.464-27.291), P=0.013]. The mortality within 100 days after allo-HSCT of patients with AKI was significantly different as compared to patients without AKI (P=0.001). Six-mouth survival rates of different class AKI patients after myeloablative allo-HSCT were (86.96±7.02)% (AKI-R), (70.00±14.49)% (AKI-I), 0 (AKI-F) (P=0.000)respectively. Conclusions AKI is one of the main complications in CML patients after myeloablative allo-HSCT. ≥Ⅲ aGVHD and increased total bilimbin are poor-prognostic factors of AKI, and higher morbidity of AKI-I and AKI-F can be found in patients with ≥Ⅲ aGVHD. With the deteriorated AKI, 6-month survival is decreased. RIFLE criteria is sensitive to the early diagnosis of renal function. Moreover RIFLE can monitor the progression of AKI and predict the clinical outcome.

Objective To analyze morbidity and prognosis of acute kidney injury (AKI) in patients with acute leukemia after myeloablative allogenetic hematopoietic stem cell transplantation (HSCT).Methods Renal function and related clinical data in 66 patients receiving myeloablative alloHSCT were retrospectively analyzed.Renal function was evaluated by RIFLE criteria,which defines AKI as three grades of severity-risk (AKI-R),injury (AKI-I) and failure (AKI-F).Results Thirtyseven recipients (56.1%) developed AKI at a median of 29 days after allo-HSCT,including AKI-R(19 recipients,28.8 %),AKI-I (11 recipients,16.7 %),AKI-F (7 recipients,10.6 %).Compared with baseline value,serum creatinine level in the recipients was significantly increased at the 21st day after transplantation (P＜0.05).During 100 days after HSCT,the morbidity of AKI-F in recipients with HVOD and without HVOD were respectively (55.56 ± 22.22)% and (9.01 ± 4.75)% (P＜0.01).The morbidity of AKI in recipients with or without increased total bilirubin was respectively (68.75 ± 24.54)% and (8.38 ± 4.17)% (P＜0.01).The morbidity of AKI in recipients with or without increased CsA concentration was respectively (66.67 ± 10.29) % and (44.44 ± 8.28) % (P＜0.05).100-day survival rate in recipients after myeloablative allo-HSCT without AKI,with AKI-R,AKI-I and AKI-F was respectively (89.66 ± 5.66) %,(83.88 ± 8.54) %,(81.82 ± 11.63) % and (42.86 ± 18.7) % (P＜0.05).Conclusion AKI is one of the main complications in patients with acute leukemia after myeloablative allo-HSCT.The influence of different class AKI on the mortality was different.The earlier diagnosis,prophylaxis and treatment of AKI by the RIFLF criteria might increase the survival rate in recipients with HSCT.

Objective To explore the anti-inflammatory effect of erythropoietin (EPO) on hepatic ischemia reperfusion (IR) injury in fatty liver rats.Methods A total of 100 male SD rats were fed with high-fat diet for 12 weeks.After the model was successfully established,the fatty liver rats were randomly divided into sham-operation (SHAM),the ischemia-reperfusion (IR) and EPO preconditioning group.Serum ALT and AST as well as hepatic histopathological changes were measured.Xanthine oxidase method was used to detect the liver tissue SOD.Thiobarbituric acid method was used to detect the MDA.Enzyme-linked immunosorbent adsorption assay (ELISA) was used to detect the plasma tumor necrosis factor alpha (TNFαt) and interleukin 1 (IL-1).Results In the EPO preconditioning groups the swelling hepatocytes was observed,but the inflammatory cell infiltration was significantly decreased and no necrosis of hepatocytes was found.ALT and AST in the EPO preconditioning groups were significantly lower than those in IR group (P ＜ 0.05).The levels of SOD activity in the EPO preconditioning groups were significantly higher,but MDA were significantly lower than that in IR group (P ＜ 0.05).The TNF-α and IL-1 in the EPO preconditioning groups were significantly lower than those in IR group (P ＜0.05).The values of ALT,AST,TNF-α,IL-1 and MDA in the EPO groups were:EPO-1 ＞ EPO-2 ＞ EPO-3 (P ＜ 0.05);but the values of SOD in the EPO groups were:EPO-1 ＜ EPO-2 ＜ EPO-3 (P ＜ 0.05).Conclusions EPO preconditioning has a protective effect against hepatic IR injury in fatty liver rats,possibly through inhibiting the inflammatory reaction to prevent the IR injury.The anti-inflammatory effect of high-dose EPO is better than that of low-dose EPO.

Objective To investigate the inhibitory effect and the effect on cell proliferation and apoptosis of artemether(ART) on human gastric adenocarcinoma cell lines and pancreatic cancer cell lines in vitro. Methods The inhibitory effect of ART on human gastric cancer cell lines(SGC-7901 and MKN-45) and human pancreatic cancer cell lines(SW-1990 and BXPC-3) were detected by MTT assay,and the effect on cell cycle and apoptosis were evaluated by flow cytometry. Results It was indicated by MTT assay that the killing effect of ART on the cancer cell lines were positively correlated to time and dosage(P

Objective To study the effect of misoprostol used to intenerate cervix and ease pain in hys- teroscopy.Methods 380 cases were divided into two groups randomly;260 cases of them were placed misoprostol 200?g in vagina 2 hours before hysteroscopy and 120 cases treated without drugs served as control.The diameter of cerical,hemorrhage,the rate of PAAS and bellyache were observed.Results The diameter of cerical,hemorrhage. the rare of PAAS and bellyache in the group of misoprostol were lower than those in the group of antitheses(P

OBJECTIVETo explore the characteristics of auditory brainstem response (ABR) in neonatal hyperbilirubinemia induced by different causes.

METHODSA total of 88 neonates (176 ears) with hyperbilirubinemia were divided into several groups according to the causes and followed up after 42 d, and 15 normal neonatus (30 ears) were measured ABR and analyzed the results.

RESULTSThe thresholds of ABR in glucose-6-phosphate dehydrogenase were the highest in all the groups and had the longest incidence rate. The wave III, V latencies and III-V, I-V interwave intervals of the ABR were significantly difference and prolonged during test in comparison to the latencies in the control group (P < 0.05). The neonatal infections group had the longest wave and interwave intervals, followed by ABO incompatibility hemolytic diseases and the unknown cause groups, while the breastfeeding jaundice were the shortest in the groups of neonatal hyperbilirubinemia. The thresholds of ABR in the hyperbilirubinemia caused by several etiologies were significant abnormality when compared with the single etiology. However, they were similar in the wave latencies and interwave intervals of ABR. During the follow up, the ABR wave latencies and interwave intervals except for interwave latency I-III were significantly shorter.

CONCLUSIONSThe toxicity of hyperbilirubinemia to the auditory nervous system are related to the species and number of etiologies. The neonate hyperbilirubinemia caused by glucose-6-phosphate dehydrogenase, infections, ABO incompatibility hemolytic diseases and many etiologies are much more dangerous to the auditory system than the breastfeeding jaundice. The damages of hyperbilirubinemia to the auditory nervous system are reversible probably.
