AIM: To study the visual quality, dry eye and biomechanical stability of patients with myopia and astigmatism after different corneal refractive surgeries. ·METHODS: A total of 986 patients with myopia and astigmatism were selected as the research object in our hospital from July 2015 to July 2016, according to the operation mode of the selection of the research object, the 986 patients were randomly divided into small incision lenticule extraction ( SMILE) group, femtosecond laser in situ keratomileusis ( FS-LASIK ) group, sub-bowman-keratomileusis ( SBK ) group and laser-assisted in situ keratomileusis ( LASIK ) group. The postoperative visual quality was determined by comparing the diopter, uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) and high-order image difference of 25d, 90d. The postoperative dry eye condition was determined by comparing the postoperative tear secretion test ( Schirmer Ⅰ test ) , tear film rupture time ( BUT ) and fluorescence staining ( FS) . The biomechanical stability of the patients was determined by comparing the corneal hysteresis ( CH ) and corneal resistance factor ( CRF ) values of the four groups. ·RESULTS: The diopter, UCVA, BCVA and high-order aberration comparison of FS-LASIK group, SBK group and LASIK group between before and after surgery, showed no significant difference ( P>0. 05 ); on diopter, BCVA, UCVA, there was no significant difference between before and after surgery in SMILE group (P>0. 05), but statistical significance difference on high order aberration (P<0. 05). The BUT and FS value of the four groups decreased obviously after operation, and the difference was statistically significant (P<0. 05). In LASIK group SIt after operation significantly decreased, with statistically significant compared with that before operation ( P <0. 05). After operation, CH and CRF of the four groups decreased with significant differences (P<0. 05). ·CONCLUSION: SMILE, FS-LASIK, SBK and LASIK are equally safe, effective and stable in the treatment of myopia and astigmatism.

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

Objective To investigate the effects of hyperthyroidism on the electrophysiological characteristics of atrium and gap junction between atrium and pulmonary vein.Methods Twenty-four rabbits were randomly divided into control group and hyperthyroid group.Atrium and pulmonary vein were dissected after the atrial effective refractory period (AERP)was measured.Connexin 43(Cx43)and Counexin 40(Cx40)protein and mRNA were determined by Western blot and semi-quantitative reverse transcription-polymerase chain reaction,respectively.Results In comparison with control group,AERP and rate adaption of AERP in hyperthyroid group were significantly shorter than that of control group( P＜0.01).The concentration of Cx43 protein in hyperthyroid group was significantly higher than that of control group,but Cx40 protein was significantly lower than that of control group(P＜0.05).The expression of Cx43 mRNA in atrium and pulmonary vein was found to be up-regulated in hyperthyroid group as compared with that of control group(P＜0.01). With the level of Cx40 mRNA,there was no significant difference between two groups.Conclusion Thyroid hormone could lead to remodeling of both atrial electrophysiology and gap junction between atrium and pulmonary vein.

Objective:To investigate the effects of estradiol on ~(60)Co?-ray induced apoptosis of bone marrow hematopoietic cells of mice,and to discuss the related anti-irradiation mechanism.Methods:KM mice were randomly divided into 3 groups(15 mice/each group):control group(without radiation),pure radiation group and estradiol+radiation group(ER group).The pure radiation group was irradiated by 4.0 Gy?-ray at a dose rate of 1.15Gy/min;the ER group was administered with 0.1 mg estradiol(IM)at 10 days before 4.0 Gy?-ray radiation;and the control group received no special treatment.The apoptotic DNA segments of bone marrow hematopoietic cells were analyzed by DNA agarose gel electrophoresis;flow cytometry was used to examine the apoptosis rate of cells and expression of Fas and Bcl-2 at 4 h,8 h,and 12 h after irradiation.Results:Eight hours after radiation,the apoptotic DNA segments were obviously increased and apoptotic DNA ladder appeared,which was not seen in the other 2 groups.The apoptosis rate of bone marrow hematopoietic cells in ER group was significantly lower than that in the pure radiation group at 4,8,and 12 h after irradiation(P

Honeybee pupae were collected from Jilin apiaries and RNA was extracted for use as a tefnplate for amplification. Based on the complete genome sequences of black queen cell virus (BQCV) published on GenBank, we designed 10 pairs of primers to amplify genes by reverse transcription-polymerase chain reaction (RT-PCR). Using this approach, we have obtained the first complete genome sequence of a BQCV isolate in China. The genome of the isolated strain, named BQCV-JL1, is composed of 8358 nucleotides and shares between 86% and 93% homology with the complete genome sequences of the other six BQCV strains published on GenBank. ORF 1 of BQCV-JL1 is positioned between nucleot ides (nt) 546 and 4676 (4131 nt), while ORF 2 is located between nt 5750 and 8203. Between the two ORFs of BQCV-JL1 there is a short ORF, called ORF 3, between nt 4891 and 5433 (543 nt). The first functional gene ex- pression domain of the BQCV-JL1 strain is positioned between nt 546 and 5 429, encompassing both ORF 1 and ORF 3. There is an internal ribosome entry site (IRES) located before ORF 2, the last three bases of which are CCU (nt 5642-5644). These bases act as an initiation.codon facilitating the translation of ORF 2. The second functional gene expression domain of the BQCV-JL1 strain is located between nt positions 5642 and 8203. The BQCV-JL1 strain was found to share high sequence identity (93%) with the Hungary 10 genotype at the whole-genome level and analysis of the nucleotide and amino acid sequences revealed that the BQCV-JL1 strain also shows close genetic relationships with the South Korea strain, suggesting that both the BQCV-JL1 and South Korea strains may have migrated from European countries. BQCV-JL1 strain was different from the other 6 strains in dividing the nucleotides positions of QRF, which vqs because of the gene mutation.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

This article reports the successful experience of integration of burn treatment and rehabilitation for a child suffering from 91% TBSA flame burn injury (with 60% TBSA full-thickness injury, 30% TBSA deep partial-thickness injury, and 1% TBSA superficial partial-thickness injury), severe inhalation injury, severe burn shock, stress ulcer, gastrointestinal bleeding and atelectasis of the right upper lung. The patient was given effective fluid infusion against shock, treatment for gastrointestinal bleeding, and other effective supportive treatment for functions of various organs after being admitted to our burn ward. When vital signs became stable at 30 hours post injury, bedside rehabilitation was begun. On post injury day (PID) 4, escharectomy was performed for both lower limbs, followed by microskin grafting and allogeneic skin covering. On PID 10, invasive infection of multi-drug resistant bacteria was found with accompanied high fever, and at the same time allograft began to disintegrate, with dissolution of large area of eschar, leading to a raw surface reaching 86% TBSA. Following debridement, dressing, application of compound polymyxin B ointment, temporary covering of wounds with porcine acellular dermal matrix, adjustment of antibiotics, patient's condition was finally stabilized. From PID 28 on, split-thickness skin grafting was conducted 7 times, and the raw surface of 75% TBSA involving the upper and lower limbs and trunk was successfully covered. At the same time, our rehabilitation team launched comprehensive rehabilitation measures comprising active exercise, occupational therapy, prevention of scar formation, organ function training and psychological intervention. Finally, the patient was able to walk unaided and fed herself when the wounds were almost entirely healed in 3 months after injury. Oriented forwards functional rehabilitation, strong cooperation between team members, and synchronous effective implementation of burn treatment and rehabilitation in the whole process are the keys to achieve successful integration of burn treatment and rehabilitation of this child.
