Posterior capsule opacification (PCO) is the most common complication after cataract surgery.How to prevent and treat PCO is an urgent problem we need to solve at present.Non-coding RNA(ncRNA) is a kind of RNA, which can not encode proteins.Studies have shown that non-coding RNA is closely related to the occurrence and development of human diseases.This paper has collected the progress of research on different kinds of ncRNA in PCO and may raise new ideas and methods on the prevention and treatment of PCO.

Objective To investigate the accuracy and availability of three‐dimensional ultrasonography ( 3DUS ) in the Bismuth‐Corlette classification of hilar cholangiocarcinoma ( HCCA ) . Methods Forty‐eight patients who underwent surgery and obtained pathologic diagnosis of HCCA were retrospectively analyzed . All patients underwent 3DUS and magnetic resonance cholangiopancreatography (MRCP) before surgery . With surgical outcomes as the gold standard ,the diagnostic efficacy of two examinations in classification of HCCA were compared . Results Forty‐eight cases of HCCA were divided into 5 types according to surgical results ,including type Ⅰ (8 cases) ,type Ⅱ(13 cases) ,Ⅲa(8 cases) ,Ⅲb (11 cases) and type Ⅳ(8 cases) respectively . Among them ,39 cases accepted radical resection and the rest of 9 cases received palliative resection . The accuracy of the Bismuth classification confirmed by 3DUS was 85 .4% (41/48) . The percentage of underestimated and overestimated classification confirmed by 3DUS were 10 .4% (5/48) and 4 .2% (2/48) respectively . The accuracy of the classification confirmed by MRCP was 87 .4% (42/48) .Both of the percentage of underestimated and overestimated classification confirmed by MRCP were samely 6 .3% (3/48) .The difference between the 3DUS and MRCP was not statistically significant(χ2 =0 .597 ,P=0 .440) . Both the percentage of underestimated and overestimated classification between 3DUS and MRCP were samely not statistically significant ( P =0 .714 , P =1 .000 ,respectively) .

Objectives To investigate the correlation between single nucleotide polymorphisms (SNP) in interleu-kin-15 (IL-15) and treatment response in childhood acute lymphoblastic leukemia (ALL). Methods Genomic DNA samples extracted from remission bone marrow cells of ALL patients were genotyped by MassArray. Five SNPs (rs10519612, rs10519613, rs17007695, rs17015014 and rs35964658) in IL-15 and their association to minimal residual disease (MRD) status in the end of induction therapy were studied. Results SNP rs17007695 was associated with the early response in children with ALL(P=0.049) and the incidence of positive MRD after induction therapy in CC genotype carriers was 1.8 times more than that in TT genotype carriers. Haplotype analysis of these five SNPs showed that the frequency of haplotype CACGG in MRD positive group was 2.1 times higher than that in MRD negative group (P=0.035). Conclusions IL-15 gene polymorphism was associated with the early treatment response in Han Chinese children with acute lymphoblastic leuke-mia.

Objective To observe and evaluate acute toxicities in a series of human immunodeficiency virus (HIV)-positive cancer patients receiving radiation therapy.Methods The study retrospectively reviewed the acute radiation reaction of radiation therapy of 14 HIV seropositive patients diagnosed with carcinoma between Feb 2008 and Dec 2013 at the Yunnan Tumor Hospital during the radiotherapy period and 1 month following treatment.Acute adverse effects were classified according to the site of radiation therapy and analyzed using the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.Results Seven patients experienced interruptions or delays in treatment,and 2 stopped treatment entirely.The most common acute adverse effects were skin reactions and mucous membrane reactions,including dermatitis,stomatitis or diarrhea.Eight patients had grade 3 acute adverse effects,including 6 patients with grade 3 skin reactions and 2 patients with grade 3 mucosa reactions.Conclusions Radiotherapy is an effective treatment for HIV positive patients with tumors,however it frequently induced severe acute radiation responses.

Objective To explore the changes in cardiac index and oxygenation index in sepsis piglets after nitric oxide (NO) gas inhalation. Methods A piglet model of sepsis was induced by intravenous infusion of Gram-negative bacterial endotoxin (LPS), then the piglets were randomly divided into two groups. NO group (n=8) was administered with inhaled nitric oxide of 80ppm via volume control (VC) mechanical ventilation for one hour, while the control group (n = 4) received mechanical ventilation with VC and was observed for one hour to assess the stability of the model. The parameters of oxygenation and hemodynamics were measured by PICCO and arterial blood gas analysis every fifteen minutes for one hour. Results Injection of endotoxin induced a stable pig model of sepsis. PH, HCO3-, arterial oxygen pressure (PaO2), mean arterial pressure (MAP) and cardiac index in this model were significantly lower the baseline values (P < 0.01). Arterial oxygen pressure and cardiac index were significantly higher in N0 group than in the control group (P<0.01). Heart rate (HR), central venous pressure (CVP), global end-diastolic volume index (GEDI) and intrathoracic blood volume index (ITBI) did not significantly differ between NO group and the control group. Conclusions Inhalation of nitric oxide gas can significantly improve oxygenation and cardiac function in piglets with sepsis.

Objective To determine the normal range of minimal erythema dose (MED) for ultraviolet A (UVA) and B (UVB) in volunteers from Urumqi region.Methods One hundred and twenty-seven volunteers including healthy subjects and patients with noninflammatory skin disorders were enrolled in this study.SUV-1000 type UV simulator was used as the light source to determine MED of UVA and UVB in these subjects.Results These subjects included 48 persons with Fitzpatrick skin type Ⅲ,79 with Fitzpatrick skin type Ⅳ,51 males and 76 females.The median MED value for UVA and UVB was 38.1 J/cm2 and 31.8 mJ/cm2 respectively in subjects with skin type Ⅲ,59.16 J/cm2 and 48.00 mJ/cm2 respectively in subjects with skin type Ⅳ.Significantly lower median MED values of UVA (both P ＜ 0.01) and UVB (both P ＜ 0.05) were observed in the male and female subjects with skin type Ⅲ compared with those with skin type Ⅳ.The male subjects showed a significantly higher median UVA-MED value (59.16 J/cm2 vs.41.10 J/cm2,P ＜ 0.05),but a similar UVB-MED value (39.60 mJ/cm2 vs.35.55 mJ/cm2,P ＞ 0.05) compared with the female subjects.No significant difference was observed in the median value of UVA-or UVB-MED in subjects with skin type Ⅲ or Ⅳ between Han and Uygur nationality (all P ＞ 0.05).Also,no correlation was found in the median value of UVA-or UVB-MED with age or duration of outdoor exposure in the male or female subjects (all P ＞ 0.05).The lower reference limit was 33.38 J/cm2 for UVA-MED and 27.90 mJ/cm2 for UVB-MED in the population in Urumqi region.Conclusion Skin phototype may be an important determinant of MED.

Objective To study the association between serum concentrations of total testosterone levels and coronary heart disease (CHD) in the postmenopausal women. Methods The study was designed as a case-control study.394 postmenopausal female patients were selected from Cardiology Center of the First Affiliated Hospital of Xinjiang Medical University.The case group included 183 women patients with CHD aged (62.7±8.0) years,the control group,211 women with normal coronary aged (60.0 ± 8.8) years. Blood samples were collected to determine total testosterone,fasting glucose and lipid profile. CHD severity was expressed as the numbers of coronary arteries that had a stenosis ≥50％.According to the level of testosteron,all cases were divided into 4 groups by interquartile range method:Q1＜3.5 nmol/L(n=190),3.5 nmol/L≤Q2 ＜10.4 nmol/L(n=64),10.4 nmol/L≤Q3 ＜26.0 nmol/L(n=120) and Q4≥26.0 nmol/L(n=20).The association between the serum total testosterone levels and severity of coronary atherosclerosis was analyzed. Results The average total testosterone was higher in case group than in control group[(10.4 ± 24.3 ) nmol/L vs. ( 6.9 ± 17.4 ) nmol/L,Z =0.79,P =0.555].In Quantitative adjusted models,higher levels of total testosterone had strong correlation with CHD,Q4 incidence of CHD (75.0％,15 cases) was significantly higher than Q1 (46.8％,89 cases),Q2 (40.6％,26 cases)and Q3 (44.2％,53 cases) (x2 =7.69,P=0.048).After adjustment for other risk factors,women in the top quartile of total testosterone levels had a more than 3-fold increase in odds of CHD(OR=3.47,95％CI:1.06-11.32,P＜0.05).In addition,the serum concentrations of total testosterone level were significantly associated with the severity of CHD (F=12.94,P＜0.05). Conclusions Higher levels of total testosterone may be associated with high prevalence and severity of CHD as an independent factor in postmenopausal women.

The purpose of the study was to observe the effect of rapamycin (RAPA) on the differentiation and maturation of rat bone marrow-derived dendritic cells (BMDCs) in vitro. BMDCs from Wistar rats were cultured with granulocyte-macrophage colony-stimulating factor plus interleukin-4 in the presence or absence of RAPA (20 ng/mL), and stimulated with lipopolysaccharide (LPS) for 24 h before cells and supernatants were collected. Surface phenotype of BMDCs was flow-cytometrically detected to determine the expression of maturation markers, MHC class II and CD86. Supernatants were analyzed for the production of IL-12 and IFN-gamma cytokines by using ELISA. BMDCs were co-cultured with T cells from Lewis rats and mixed lymphocyte reaction was assessed by MTT method. The morphology of BMDCs stimulated with LPS remained immature after RAPA pretreatment. RAPA significantly decreased the CD86 expression, impaired the IL-12 and IFN-gamma production of BMDCs stimulated with LPS, and inhibited the proliferation of allogeneic T cells. In conclusion, RAPA can inhibit the maturation of BMDCs stimulated with LPS in terms of the morphology, surface phenotype, cytokine production, and ability of BMDCs to stimulate the proliferation of allogeneic T cells in vitro.
