Objective To describe an ideal technique to repair full-thickness lower lid marginal defects in a one-stage procedure. Methods The buccal rotation flap and the nasal septal chondromucosal flap were used in one-stage operation to repair full-thickness lower eyelid defect. Results Eleven patients including 6 male patients and 5 female patients underwent lower eyelid reconstruction since January 2000.The age ranged from 29 to 64 years with average 43. Seven patients with full-thickness lower eyelid defect were caused by basal cell carcinoma excision, while four patients were caused by trauma. All the fullthickness lower eyelid defects were reconstructed by using the buccal rotation flap and the nasal septal chondromucosal flap in one-stage operation. All the flaps survived completely after operation. There were no other complications excepting that two patients developed to mild lower eyelid retration after six months. Conclusion The technique consisting of the buccal rotation flap and the nasal septal chondromucosal flap is a simple and useful alternative procedure to close full-thickness defects in the lower eyelid.

Objective To study the protective effects of vitamin E combined with Rhodiola rosea on the injury in mice skeletal muscle through hypoxia with exercise training and research the mechanism of action.Methods Forty ICR mice were randomly divided into control group and observation group,20 mice in each group.The control group was given Vitamin E (40 mg·kg-1·d-1),and the observation group was given Vitamin E (40 mg·kg-1·d-1)combined with Rhodiola rosea (20 g·kg-1·d-1);the rats in the two groups were treated with hypoxia (11.3%) for 4 weeks (5 ℃,15 m/min,60 min/d) after 15-day drug using.After the last training,all the mice were euthanized and then detected the gene of Bax and Bcl-2 mRNA through the RT-PCR in the skeletal muscle and the activity of GSH-PX,SOD,ROS,the concentration of MDA in the skeletal muscle.During the period (pretrain and 1,2,4 weeks) of hypoxia combined with exercise training,the CK,LDH in the serum were detected.Results The expression of CK and LDH in the observation group were lower than those of the control group (P<0.05).The activity of GSH-PX and SOD in the skeletal muscle of the observation group was significantly higher than that of the control group (P<0.05),while the ROS and MDA were lower than those of the control group(P<0.05);the expression of Bax mRNA and Bax/Bcl-2 of the observation group was significantly lower than that of the control group(P<0.05).While the expression of Bcl-2 mRNA was significantly higher than that of the control group(P<0.05).Conclusion Rhodiola rosea combined with Vitamin E can inhibit the expression of apoptotic genes by correcting the oxidation and hypoxia imbalance under hypoxia.

Objective: To explore the genetic cause for abnormal pregnancies through detecting chromosomal copy number variations (CNVs) in abortic tissues by next generation sequencing (NGS). Methods: NGS technique was used to detect CNVs in abortion tissues. Parental chromosomal karyotypes were predicted based on the results. The aberrant chromosomal segments of the parents were accurately mapped by G-banding karyotyping analysis and fluorescence in situ hybridization (FISH). Results: In addition to numerical chromosomal aberrations, 12 microdeletion/microduplications were detected by NGS. For 8 families where both parents accepted chromosomal karyotyping, 4 carriers of chromosomal abnormalities were identified. One marker chromosome was missed by karyotyping analysis, and a mother was confirmed to carry a cryptic balanced translocation by FISH. Conclusion NGS can facilitate detection of cryptic chromosomal translocations in couples with repeated pregnancy failure and is of great value for detecting abnormal CNVs for its high sensitivity.

Objective To investigate the effect of long non-coding RNA F19 (lncRNA F19) on secondary brain injury following traumatic brain injury (TBI) in mice. Methods (1) A total of 96 C57BL/6J male wild-type mice were divided into sham group, sham+control lentivirus group, sham+F19 lentivirus group, TBI group, TBI+control lentivirus group and TBI+F19 lentivirus group according to the random number table. Each group consisted of two subgroups of 1 day and 3 days after TBI, with eight mice per subgroup. The expression and silence efficiency of lncRNA F19 were detected. ( 2 ) A total of 96 C57BL/6J male wild-type mice were divided into sham group, TBI+control lentivirus group and TBI + F19 lentivirus group according to the random number table. Each group consisted of two subgroups of 1 day and 3 days after TBI, with 16 mice per subgroup. The effect of lncRNA F19 on neuronal apoptosis after TBI was recorded. The mice TBI model was established using the controlled cortical damage method (CCI). The lncRNA F19 lentivirus or control lentivirus were administrated by intracerebroventricular injection 5 days before injury. The expressions of lncRNA F19 ( 2 -ΔΔct ) were detected by real-time quantitative PCR ( qRT-PCR ) at 1 day and 3 days after injury. The Toll-like receptor 4 (TLR4), B lymphocyte tumor-2 (Bcl-2) and Bcl-2 related protein (Bax) expressions were detected by Western blot. The TUNEL was used to detect apoptosis around the traumatic lesions. Results From the first day after injury, both in the sham operation and TBI groups, the control lentivirus had no effect on the level of lncRAN F19 (P >0. 05). One day after injury, compared with sham +control lentivirus group, the levels of lncRNA F19 in sham + F19 lentivirus group were significantly decreased (0. 07 ± 0. 07:0. 93 ± 0. 17);compared with TBI+control lentivirus group, levels of lncRNA F19 in TBI+F19 lentivirus group were significantly decreased (2. 91 ± 1. 18:0. 52 ± 0. 32) (P<0. 05). There were significantly lower protein levels of TLR4 (0. 51 ± 0. 13:0. 66 ± 0. 15), Bax (0. 45 ± 0. 06:0. 67 ± 0. 16), lower TUNEL-positive neurons ratio [(23. 55 ± 6. 85)％ : (31. 58 ± 7. 52)％], but higher protein levels of Bcl-2 (0. 76 ± 0. 16:0. 47 ± 0. 12) in TBI+F19 lentivirus group compared with the TBI+ control lentivirus group (P <0.05). Three days after injury, compared with sham + control lentivirus group, levels of lncRNA F19 in sham+F19 lentivirus group were significantly decreased (0. 11 ± 0. 09:0. 96 ± 0. 09); compared with TBI+control lentivirus group, levels of lncRNA F19 in TBI+F19 lentivirus group were significantly decreased (0. 54 ± 0. 24:3. 39 ± 0. 90) (P <0. 05). There were significantly lower protein levels of TLR4 (0. 60 ± 0. 20):(0. 85 ± 0. 09)], lower Bax (0. 60 ± 0. 12:0. 88 ±0. 21), lower TUNEL-positive neurons ratio [(29. 10 ± 7. 37)％ :(39. 22 ± 10. 64)％], but higher protein levels of Bcl-2 (0. 66 ± 0. 12:0. 35 ± 0. 16) in TBI+F19 lentivirus group compared with the TBI+control lentivirus group (P<0. 05). Conclusion Inhibition of lncRNA F19 can significantly reduce the TLR4-induced neuronal apoptosis in cortex after TBI in mice and alleviate reduce the secondary brain injury.

Objective: To observe the expression levels of PD-1/PD-L1 costimulatory molecules and explore the clinical significance in patients with chronic lymphocytic leukemia (CLL) . Methods: The expression of PD-1/PD-L1 in peripheral blood CD8⁺ T cells, CD4⁺T cells, CD19⁺B, and dendrites cells (DC) was detected by flow cytometry in 57 CLL patients and 20 healthy controls. The correlations of PD-1/PD-L1 expression with disease stage, CD38 expression, ZAP-70 expression, chromosome karyotype abnormality and β₂-MG expression were analyzed. Results: ①Compared with control, CLL patients, including 39 males and 18 females with the median age of (63.7±10.7) years, had no statistically significant difference in age and gender (P>0.05) . CLL patients had the higher PD-1/PD-L1 expression than healthy controls (P<0.05) . ②In Rai staging, the later the stage, the higher expression of PD-1/PD-L1 (P<0.05) . ③PD-1 expression in CD8⁺CD38⁺ group (11 cases) was higher than that in CD8⁺CD38^- group (46 cases) (P=0.004) , and CD8⁺ poor prognosis chromosome group (14 cases) also had significant higher PD-1 expression than CD8⁺good prognosis chromosome group (28 cases) (P=0.004) . ④The expression of PD-L1 was higher in CD38⁺group, ZAP-70⁺group, and poor prognosis group, as compared to that in CD38^-group (P=0.002) , in ZAP-70^-group (P<0.001) , in good prognosis group (P=0.023) . There was no correlation between the expression of PD-1/PD-L1 and β₂-MG (P>0.05) . Conclusion This data reveals that PD-1/PD-L1 was highly expressed in CLL patients. Its expression levels were correlated with Rai stage, CD38, ZAP-70, chromosome karyotype, but not with β₂-MG. PD-1/PD-L1 may be a prognostic factor in patients with CLL.

Objective:To explore the expression levels, clinical significances and prognostic evaluation value of T-cell immunoglobulin mucin-3 (Tim-3) and galectin-9 (Gal-9) in bone marrow cells of patients with newly diagnosed acute lymphocytic leukemia (ALL).Methods:Bone marrow samples from 30 newly diagnosed ALL patients admitted to First Affiliated Hospital of Xinjiang Medical University from September 2016 to September 2018 were selected, and peripheral blood samples from 20 healthy volunteers during the same period in the First Affiliated Hospital of Xinjiang Medical University were treated as the controls. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect mRNA relative expression levels of Tim-3 and Gal-9. Differences in mRNA expression of Tim-3 and Gal-9 among ALL patients with varied clinicopathological characteristics were compared. Overall survival (OS) analysis was performed by using the Kaplan-Meier method, Cox proportional hazards model was used to make univariate and multivariate survival analysis.Results:mRNA relative expression levels of Tim-3 and Gal-9 in 30 newly diagnosed ALL patients were higher than those in the healthy control group (2.86±0.47 vs. 0.45±0.05, t = 21.65, P<0.05; 9.79±0.58 vs. 0.96±0.23, t = 63.24, P<0.05). mRNA relative expression level of Tim-3 had statistically significant differences in patients with different ages, France-America-Britain (FAB) Cooperative Group classification, hazard grades and central nervous system invasion (all P<0.01). There were statistically significant differences in mRNA relative expression level of Gal-9 for patients with different ages, FAB Cooperative Group classification, white blood cell count (WBC), central nervous system invasion and NOTCH1 mutation (all P<0.01). All patients were grouped by mRNA relative expression levels of Tim-3 and Gal-9, and patients in high Tim-3 expression group (≥2.86) had worse overall survival (OS) compared with that for patients in low Tim-3 expression group (<2.86) ( P = 0.048). Patients in high Gal-9 expression group (≥9.79) had worse OS compared with that for patients in low Gal-9 expression group (<9.79) ( P = 0.031). Moreover, the OS in Tim-3 and Gal-9 both high expression group was worse than that in Tim-3 and Gal-9 both low expression group and in the low expression group of either of them (all P<0.05). There was no statistically significant difference in OS between the high Tim-3 expression with low Gal-9 expression group and the high Gal-9 expression with low Tim-3 expression group ( P > 0.05). Multivariate Cox regression analysis revealed that peripheral blood WBC≥11.4×10 9/L, BCR-ABL gene mutation, central nervous system invasion, and high expression of Tim-3 and Gal-9 were independent risk prognostic factors of OS for newly diagnosed ALL patients (all P<0.05) . There was a positive correlation between the expression levels of Tim-3 and Gal-9 ( r = 0.788, P<0.01). Conclusions:The high expression of Tim-3 and its ligand Gal-9 are independent effecting factors of poor prognosis in newly diagnosed ALL patients. The expression levels of Tim-3 and Gal-9 can be served as a potential prognostic indicator for ALL patients.
