AIM:To explore the clinical outcomes of RS lacrimal tube for lacrimal canaliculi rupture without nasal endoscope.

METHODS:A retrospective analysis from September 2017 to March 2018 were taken. According to admission time sequence. Totally 52 patients with lacrimal canaliculi rupture was divided into two groups. One group was treated with RS lacrimal tube, the other was treated with annular silicone tube. The treatment results were comparatively analyzed.

RESULTS:There were 15 eyes of nasal mucosa hemorrhage in annular silicone tube group. There was no eye with this in RS tube group, the difference between the two groups was significant(P<0.001). In RS tube group, 26 eyes were cured, 3 eyes improved, 3 eyes failed. The effective rate was 91%. In annular silicone tube group, 15 eyes were cured, 3 eyes improved, 2 eyes failed. The effective rate was 90%, the clinical efficacy was not significantly different between groups(P=0.877). There were 2 eyes in RS tube group occurred fall off in 2wk to 2mo after operations; 1 eye of lacrimal puncture were removed from the lacrimal puncture without 2wk, and was anastomosed again. The other eye was removed from the lacrimal puncture within 1-2mo after the operation, the lacrimal canal flushing was improved during follow-up. There were 3 eyes in annular silicone group occurred fall off without 2wk, and were not anastomosed again. The lacrimal duct flushing was improved during follow-up. No statistical significance was found in the two groups(P=0.361).

CONCLUSION:Lacrimal canaliculi rupture should be timely given surgical treatment. RS lacrimal tube can not only achieve good operation effect and reduce the probability of complications, but also has the advantages of simple surgical methods, good histocompatibility and no influence on the appearance of patients.

OBJECTIVE: To investigate the effect of long non-coding RNA-TUC338 on the proliferation and migration of lymphoma cells. METHODS: The expression of TUC338 in different lymphoma cells was detected by fluorescence quantitative PCR, cell proliferation by sulforhodamine B (SRB) assay, migration of lymphoma cells by transwell assay, and protein expression in PI3K/AKT signaling pathway by Western blot. RESULTS: The expression levels of TUC338 in lymphoma cells Daudi, U937, BC-3, and Raji significantly increased in comparison with human normal T lymphocytes H9 (t=13.277, 10.103, 16.200, and 26.687, P=0.002, 0.005, 0.001, and 0.000). Compared with NC-siRNA group, the number of cells crossing the chamber of TUC338-siRNA group was significantly reduced (t=30.508, P=0.000), the protein expression levels of p-PI3K and p-AKT significantly decreased (t=16.872 and 18.371, P=0.000 and 0.000), and OD CONCLUSION The expression of TUC338 significantly increases in lymphoma cells, and silence of TUC338 effectively inhibits the activation of PI3K/AKT signaling pathway, thereby inhibiting the proliferation and migration of lymphoma cells, which has a potential application value in diagnosis and treatment of lymphoma.

OBJECTIVETo investigate the expression of LncRNA KCNQ1OT1 in patients with acute myeloid leukemia (AML) and to analyze the relation of LncRNA KCNQ1OT1 expression levels with clinicopathological features.

METHODSA total of 68 patients with AML were enrolled in the study, 48 out of them were suffered from acute myeloid leukemia (AML) and 20 reached to complete remission (CR), 30 age-matched patients with iron-deficient anemia were included in control group, the peripheral blood samples of all the patients were collected, and the real-time fluorescent quantitative PCR (qRT-PCR) was used to detect the expression of LncRNA KCNQ1OT1, meanwhile, the correlation of its expression with clinicopathological characteristics and prognosis was analyzed.

RESULTSThe expression of LncRNA KCNQ1OT1 in AML patients was significantly higher than that in the patient with complete remission and iron-deficient anemia (F=14.67, P<0.01). The expression of LncRNA KCNQ1OT1 was not significantly different between 20 cases of AML-CR and 30 cases of iron-deficient anemia (P>0.05). The expression of LncRNA KCNQ1OT1 was associated with NCCN risk grade and survival status in patients with AML. The median overall survival time was significantly shorter in patients with high expression of LncRNA KCNQ1OT1 than that in patients with low expression(P<0.05).

CONCLUSIONLncRNA KCNQ1OT1 may be involved in the regulation of AML. Expression of LncRNA KCNQ1OT1 and NCCN risk score can be used as biomarkers of prognosis in the patients with AML and may be a potential prognostic marker and therapeutic target for AML patients.

OBJECTIVE: To assess the influence of nasal adenoidal hypertrophy (AH) in children on the mandibular growth pattern. METHOD: The patients were divided to two groups aged from 3 to 12 years. In the AH group (30 children), the cases who had symptom of NAO for more than two years and A/N > or = 0.71 (the adenoids/nasopharynx according to the cephalometry) were selected. In the control group (28 children), the cases who had no symptom of NAO and A/N < or = 0.60 were selected. All data of acoustic rhinometry (AR) and cephalometry were analyzed. RESULT: Compared with the controls, the total nasal airway resistance (TNAR) was significant increased (P < 0.01), the bilateria nasal cavity minimal cross sectional area (MCSA) was significant decreased (P < 0.01), and the nasopharyngeal volume (NPV) was significant decreased (P < 0.01). There were significant differences between the AH group and the controls in TNAR, NPV and MCSA. Comparing with the controls,the children with AH showed apparently vertical growth pattern, and larger gonion and retrusion chin. There was positive correlation between NPV and FH ratio. CONCLUSION It indicated that AH might be one of the factors related to the difference of craniofacial morphology, especially of the mandibular growth pattern.
