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.

ObjectiveTo evaluate the application of chest-abdomen longitudinal diameter ratio,total lung area and lung longitudinal diameter in different gestational ages by two-dimensional ultrasonography.MethodsFive hundred and ninty-two fetus of normal singleton pregnancy between 18 and 40 weeks were ultrasonic scanned by standard 4-chamber view and fetus torso coronal section.The heart area,thoracic area,bilateral lungs pointed to the corresponding diaphragmatic dome gallery on the top of the vertical distance,diaphragmatic dome iterated top to the bottom of the fetal bladder distance were measured respectively.Related regression analysis was done on fitting total lung area and longitudinal diameter with pregnant increasing.ResultsA normal pregnancy fetal total lung area and lung longitudinal diameter were increased as long as the gestational age.The best-fit regression equations of total lung area was:Y =0.83 X +13.894,R2 =0.914;Lung longitudinal diameter was:Y =0.669 X + 3.124,R2 =0.892.Chest-abdomen longitudinal diameter ratio from 18 to 40 weeks gestation was in constant range:0.44 - 0.59.Conclusions Chest-abdomen longitudinal diameter ratio from 18 to 40 weeks gestation is in constant range.The normal pregnancy fetal total lung area and lung longitudinal diameter were increased as long as the gestational age.These parameters may be useful for the prenatal assessment of lung development.

Objective To explore the application effect of the improved lateral decubitus position in the operation.Methods 160 cases were randomly divided into the modified lateral surgical group and traditional group two groups (n =80 for each group).Fourth edition of the traditional group was “routine medical care and technical operations” approach placed.Modified group:before anesthesia,a small pad under the chest wall soft pillow,according to lesion location after anesthesia choose left or right lateral position,his hands in front of music was set to sleep like the two arms of a small soft pillowbetween the pad; Front legs apart,on the tuiqu Xi,the next leg straight; head elevated after the first lap put the gap at the ear; Chest and abdomen and the back of each fixed a cylindrical yam bags,and finally tied with fixed hip,knee.Placed in two groups were observed an average completion time position,the incidence of intra-operative movement position,pressure and skin after postoperative follow-up physical fatigue,nerve damage,etc.Results Placed in modified group method average completion time is shorter than the traditional group,skin pressure,body fatigue,nerve injury rate of postoperative complications was significantly lower than the traditional group,intra-operative position more stable than the traditional group [ ( 13.97 ± 1.63 ) vs (6.71 ± 12.9 ),t =31.238,P ＜ 0.01 ; x2 =6.826 7,8.901 1,1 1.756 6,P ＜ 0.01 ).Conclusions Placed by the improved method can shorten the display side of time.For BP,HR,SpO2,respiration rate change had no effect,and complications of place due to improper posture can be significantly reduced and further enhance the quality of surgical care.

Objective To observe the effect of mirror therapy on persistent pain after breast cancer surgery,and to improve the quali-ty of life of the patients. Methods From September,2016 to June,2017,62 patients with persistent pain after breast cancer surgery were selected. They were randomly divided into control group(n=31)and mirror group(n=31).Both groups received routine re-habilitation,and the mirror group received mirror action in addition,30 minutes every time,five times a week for four weeks. The severity of pain was assessed with Numerical Rating Scale (NRS) before treatment, and four weeks,eight weeks and twelve weeks after treatment.The quality of life was assessed with European Organiza-tion for Research and Treatment of Cancer Quality of Life Questionnaire-30(EORTC QLQ-C30). Results Eight and twelve weeks after treatment,the NRS score was lower in the mirror group than in the control group (F>5.907,P<0.05).Twelve weeks after treatment,the total health status score of EORTC QLQ-C30 was higher in the mirror group than in the control group(t=2.128,P<0.05). Conclusion Mirror therapy could relieve the persistent pain after breast cancer surgery, and may help to improve the quality of life of the patients.

The study was purposed to investigate the polymorphism of killer cell immunoglobulin-like receptor (KIR) gene of the patients with leukemia and to explore the correlation between the KIR gene and susceptibility of leukemia. The KIR genotype of 50 patients with leukemia and 60 healthy controls in northern. Hans were analyzed by PCR-SSP. The results indicated that the present known 18 KIR genes were detected and identified. The frequencies of KIR 3DL3, 3DL2 and 2DL4 were 100% in all subjects, with the most frequent genotype KIR 3DP1 (0.86) followed by 2DP1, 2DL3, 3DL1, 2DL1, 3DS1, 2DL5, 2DS4, 2DS2, 1D, 2DS5, 2DL2, 2DS1, 2DS3 and 3DP1v in leukemia successively. Compared with the control, the KIR 3DL1 (0.60) and 2DL1 (0.57) were significantly lower in the leukemia patient group than that in the control group (1.00) (P < 0.01). It is concluded that the polymorphism of KIR gene is associated with susceptibility of leukemia in Hans. There may be a negative correlation between pathogenesis of leukemia and KIR 3DL1, KIR 3DS1, KIR 2DL1, KIR 2DL5 genes.

OBJECTIVETo investigate the pathogenic mechanisms of airway inflammation and recurrent wheezing induced by recurrent respiratory virus infection after respiratory syncytial virus (RSV) infection.

METHODSSixty-four female BALB/c mice (aged 6-8 weeks) were randomly divided into four groups: control, RSV, Poly(I:C), and RSV+Poly(I:C) (n=16 each). The bronchoalveolar lavage fluid (BALF) was collected on the 3rd day after Poly(I:C) administration, and the total cell number and differential counts in BALF were determined. Hematoxylin-eosin staining was used to observe pulmonary pathological changes. The airway responsiveness was detected. ELISA was used to measure the levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), interleukin-13 (IL-13), matrix metallopeptidase-9 (MMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in BALF.

RESULTSCompared with the other three groups, the RSV+Poly(I:C) group had significant increases in the total number of inflammatory infiltrating cells in the airway, airway responsiveness, and MMP-9 level in BALF (P<0.05). The RSV+Poly(I:C) group showed more severe pulmonary tissue injuries compared with the control and RSV groups (P<0.01). Compared with the RSV group, the RSV+Poly(I:C) group showed significant reductions in the levels of IL-4 and TIMP-1 in BALF (P<0.01).

CONCLUSIONSViral re-infection in the late stage of RSV infection may cause an imbalance of MMP-9/TIMP-1 expression and thus contribute to aggravated airway inflammation.

This study aims to investigate the characteristics of genomic variation of pandemic A/H1N1/2009 influenza virus isolated in Fujian Province, China. Complete genome sequence analysis was performed on 14 strains of pandemic A/H1N1/2009 influenza virus isolated from Fujian during 2009-2012. All virus strains were typical low-pathogenic influenza viruses, with resistance to amantadine and sensitivity to neuraminidase inhibitors. Eight genome fragments of all strains were closely related to those of A/California/07/2009 (H1N1) vaccine strain, with > or = 98.2% homology. Compared with the vaccine strain, the influenza strains from Fujian had relatively large variation, and variation was identified at 11 amino acid sites of the HA gene of A/Fujiangulou/SWL1155/2012 strain, including 4 sites (H138R, L161I, S185T, and S203T) involved inthree antigen determinants (Ca, Sa, and Sb). In conclusion, the influenza vaccine has a satisfactory protective effect on Fujian population, but the influenza strains from Fujian in 2012 has antigenic drift compared with the vaccine strain, more attention should therefore be paid to the surveillance of mutations of pandemic A/H1N1/2009 influenza virus.

OBJECTIVETo study the clinical efficiency, electroencephalogram (EEG) changes and cognitive improvements of ketogenic diet (KD) in children with refractory epilepsy.

METHODSTwenty pediatric patients (7-61 months in age) with refractory epilepsy were recruited between August 2012 and August 2013. KD therapy was performed on all participants for at least 3 months based on a fasting initiation protocol with the lipid-to-nonlipid ratio being gradually increased to 4 : 1. Seizure frequency, type and degree were recorded before and during KD therapy. A 24 hours video-electroencephalogram (V-EEG) examination and Gesell Developmental Scale assessment were performed prior to KD therapy, and 3, 6, 9 months after KD therapy.

RESULTSSix patients became seizure free after KD therapy, with a complete control rate of 30%. Seizure frequency reduction occurred in 13 (65%) patients, EEG improvement in 8 (40%) patients, and improvement in Gesell Developmental Scales (gross motor and adaptability in particular) in 6 (30%) patients. The KD therapy-related side effects were mild.

CONCLUSIONSKD therapy is safety and effective in reducing seizure frequency and improving EEG and cognitive function in children with refractory epilepsy.
