Corneal neovascularization is a significant and sight-threatening complication of many ocular surface disorders, and may cause corneal sear and rejection reaction after corneal grafting. Recent studies have revealed that vascular endothelial growth factor (VEGF) plays an important role in corneal neovascularization, and inhibition of VEGF has become a main strategy for treatment of corneal neovascularization. This article reviews the research progress in inhibition of corneal neovascularization by anti-VEGF therapy.

Objective To approach the effective treatment for simple bone cyst in adult. Methods Forty-eight cases were divided into two groups by visiting order, 20 cases (steroid group) were treated by prednisolone acetate and 28 cases (open resection and allograft group) were treated by open resection and allograft. The curative effect were contrasted between two groups. Results The follow-up time was 5-46(26.58 ± 10.81) months. Aecording to the Chigira's healing criteria for simple bone cyst, grade Ⅰ , Ⅱ , Ⅲ,V were 1, 2, 10 and 7 cases respectively in steroid group, contrasting to 0, 3, 5 and 20 cases respectively in open resection and allograft group. The recovery rate was 85.0%(17/20) in steroid group and 89.3%(25/28) in open resection and allograft group, which was no statistically significant difference between two groups (P＞0.05). Conclusions Although the two remedies are no obvious difference in curative effect,simple bone cyst at lower extremity of weight-bearing with obvious osteolysis in adult is recommended to open resection and allograft, otherwise or at upper extremity to steroid injection.

Objective To investigate the influence of combined irbesartan/hydrochlomthiazide on morning blood pressure surge(MBPS)and left ventricular mass(LVM) in essential hypertension.Methods After 4-8 weeks' run-in period,if blood pressure wagn't up to the standard,the 120 patients were given irbesartan/hydrochlorothiazide once daily from 150 mg/12.5 mg for 12 months to 300 mg/25mg for another 12 months.MBPS was conducted by arnbuhry blood pressure monitoring(ABPM)and LVM was determined by echocardiography at the end of placebo baseline and 12 months later.Results (1)After treatment the patients with MBPS(+)decreased and patients with MBPS(-) increased.(2)After treatment the extents of MBPS were reduced in MBPS(+)patients[systolic blood pressure(SBP)difference(16.1±1.8)mm Hg(1mm Hg=0.133 kPa)vs(29.4±2.8)mm Hg,diastolic blood pressure(DBP)difference(10.2±2.3)mm Hg vs(21.2±2.2)mm Hg,P<0.01]with little change in MBPS(-)patients[SBP difference(11.2±2.4)mm Hg vs(10.1±1.2)mm Hg,DBP difference(5.9±1.9)mm Hg vs(6.8±3.2)mm Hg]compared with before treatment.(3)LVM indexes of all patients were significantly reduced.Conclusion Irbesartan/hydrochlorothiazide can effectively attenuate the extent of MBPS, and has advantages on reversing left ventricular hypertrophy.

Objective To explore the impacts of intensive nutritional intervention on maternal and infant outcomes in women with gestational diabetes mellitus(GDM). Methods From January 2014 to ecember 2014, a total of 518 women with GDM were stratified by age, height, body mass index (BMI), and were divided into treatment group (n=258) and control group (n=260) according to the random number generated by the computer software. Women in control group underwent conservative treatment while those in treatment group were given intensive nutritional intervention including keeping records of eating habits, measurement of blood glucose and regular follow-up. The incidence of pregnancy-related complications and newborn outcomes in both groups were compared. Results Women of the two groups were similar in basic clinical data. The range of gestational weight gain (GWG) [(12.2 ± 4.7) vs. (13.9 ± 5.0)kg] and birth weight of infants [(3 406.4±495.4) vs. (3 494.9±484.7)g] in the intervention group was significantly lower than those in the control group (P<0.01). The rate of reaching recommended target of GWG was significantly higher in the intervention group (60.9%) than in the control group (51.9%, χ2=4.2, P<0.05). There was a significant reduction in glucose-related parameters in both groups (P<0.01). In the intervention group, fasting blood glucose and postprandial blood glucose were reduced from (5.21 ± 0.71) mmol/L, (6.68 ± 0.90) mmol/L to (4.71 ± 0.73) mmol/L,(6.21 ± 0.71) mmol/L (P<0.01), respectively in comparison with the control group, the intervention group had lower incidence of cesarean section (44.6% vs. 53.8%), postpartum hemorrhage (2.3%vs. 6.2%), polyhydramnios (7.8%vs. 13.5%), neonatal hypoglycemia (3.1%vs. 6.5%) and macrosomia (8.1%vs. 13.8%, P<0.05). Conclusions Strengthening nutritional intervention in women with GDM could increase the rate of reaching recommended target of GWG, improve the glucose-related parameters and reduce the incidence rate of pregnancy complications.

OBJECTIVE:To evaluate the feasibility and initial outcome of reconstructing the defect femur by unicondylar osteoarticular altograft after resection of distal femur tumor.METHODS:Between July 2003 and August 2008,a total of 12 patients with distal femur tumor treated by unicondylar resection and fresh-frozen unicondylar osteoarticular allograft reconstruction of bone defects were retrospectively reviewed at the Department of Orthopedics,General Hospital of Chinese PLA.Of 12 patients,5 medial and 7 lateral femoral condyles were involved.There are 8 patients suffering from giant cell tumor,including 2 patients complicating with pathologic fracture,3patients suffering from osteosamoma and 1 patient suffering from low-grade fibrosarcoma.Before transplantation,MRI and/or CT were used to determine that the tumor was definitely limited in half condyle.Three cycles of chemotherapy preoperatively and six cycles of chemotherapy postoperatively were conducted in patients suffering from osteosarcoma and fibrosarcoma.Patients with giant cell tumor did not receive any intraoperative adjuvant treatment.The surgical margin of resected tumors was evaluated by histological examination.All patients were followed by radiograph or CT.Postoperative function was evaluated by Musculoskeletal Tumor Society (MSTS) scoring system at the time of the latest follow-up.RESULTS:All patients were followed up.The patients were followed up mean 35 months after transplantation.None of the patient died.No local recurrences and metastases were found at the latest follow-up.No evident immune rejection and deep infection were seen.No plate loosening or breakage was observed.All patients had their grafts retained at the time of the latest follow-up.Three patient's allograft showed subchondral bone collapse and articular deterioration,but the function was good.Instability of the knee joint was noted in 3 patients.The mean MSTS functional score (totally 30 points) was 26 points.CONCLUSION:For some patients with giant cell tumor or malignant tumors with clearly defined margins after chemotherapy.When the lesions were limited in half condyle and enough surgical margins can be achieved,reconstruction of bone defect with unicondylar osteoarticular allografts after bone tumors were resected appears to be a reliable alternative.

Objective To determine whether the 12-lead-resting electrocardiogram(ECG) is a predictor of left vertricular(LV) recovery after successful recanalization of chronic total coronary occlusions(CTO).Methods The 12-lead-resting ECG was evaluated for Q-wave areas and parameters of QT dispersion.Impairment of regional wall motion was evaluated by real-time three-dimensional echocardiography(RT-3DE) at baseline and at follow-up.Results The wall motion score index(WMSI) was improved from 1.56?0.31 to 1.12?0.21(P0.05).Conclusion In patients with recanalization of CTO,recovery of regional wall motion is reliably predicted by analysis of the12-lead-resting ECG.

Objective: To use autophagy inhibitors combined with radiation to treat the oral squamous cell carcinoma CAL-27 and KB cells,and to explore the influence of autophagy in the oral cancer radiation sensitivity and its mechanisms. Methods:The human oral squamous cell carcinoma CAL-27 and KB cells were divided into control group,CQ group,3-MA group,IR group,CQ+IR group,and 3-MA+IR group. The survival rate was detected by MTT method and the autophagy of CAL-27 cells was observed by immunofluorescence method and laser scanning confocal microscope.The expression levels of LC3 and beclin-1 were detected by Western blotting method. The apoptotic rate was determined by flow cytometry with Annexin Ⅴ/PI doulde staining. Results:Compared with IR group,the survival rates in 3-MA + IR and CQ+ IR groups were signifcantly decreased (P < 0.05 ).The autophagy levels of cells in IR group were significantly higher than those in control group, CQ group, 3-MA group,CQ+IR group,and 3-MA+IR group (P <0.05).The expression levels of LC3 and beclin-1 proteins in IR group were significantly higher than those in control group,CQ+ IR group,and 3-MA+ IR group (P < 0.05). The apoptotic rates in IR,3-MA+ IR,and CQ+ IR groups were markedly higher than those in control group. Compared with IR group,the apoptotic rates in CQ+IR and 3-MA+IR groups were significantly increased (P <0.05).Conclusion:Radiotherapy can induce the increase of autophagy level of oral squamous cell carcinoma cells. Inhibiors of autophagy can increase the radio-sensitivity of oral squamous cell carcinoma cells by inhibiting the proliferation and inducing the apoptosis.

Objective:To investigate the effect of poly (lactic acid)(PLA)electrospun membranes loaded with cisplatin and chloroquine on the oral squamous cell carcinoma CAL-27 cells,and to explore the method to prevent the recurrence of oral cancer.Methods: The DDP/PLA membranes, CQ/DDP/CQ/PLA membranes and CQ/DDP/PLA membranes were prepared by electrospinning.Then the micro morphology of three kinds of membranes were observed by scanning electron microscope (SEM);the degradation rate of PLA membrane was measuredby UV spectrophotometric.The LC3-Ⅱ expression level in CAL-27 cells was detected by laser scanning confocal microscope.The survival rate of CAL-27 cells was detected by MTT method.Results:The SEM results showed that the nanofibers of DDP/PLA,CQ/DDP/PLA and CQ/DDP/CQ/PLA membranes were continuous and smooth with uniform diameters.The degrated time of membranes was about 21 d.The MTT result showed that compared with control group,at first,the effects of cell killing of DDP/PLA membranes,CQ/DDP/CQ/PLA membranes and CQ/DDP/PLA membranes were not obvious;as the extension of time,the survival rates of CAL-27 cells in DDP/PLA membranes group,CQ/DDP/CQ/PLA membranes group and CQ/DDP/PLA membranes group were decreased (P <0.05).The immunofluorescence results showed that the fluorescence intensity of LC3-Ⅱ in CQ/DDP/CQ/PLA membranes group and CQ/DDP/PLA membranes group were lower than that in DDP/PLA membranes group.Conclusion:CQ/DDP/PLA membranes with sustained-release effect can increase the sensitivity of CAL-27 cells to DDP and enchance the killer effect of DDP on the CAL-27 cells.
