?AlM:To explore the influence factors of orthokeratology controlling development of juvenile myopia.
?Methods: A retrospective analysis of 86 cases ( 169 eyes ) who performed orthokeratology from November 2012 to November 2013 in our hospital was carried out. Ater 2a treatment, diopter increased > -0. 25D as invalid control group (54 eyes), diopter increased ≤ -0. 25D as effective control group ( 115 eyes ) . The difference of various factors between two groups were compared.
?RESULTS: Univariate comparison showed that the two groups had no statistical significance (P>0. 05) in terms of gender, whether wear glasses in the past, anterior corneal diameter before treatment, central corneal thickness, intraocular pressure and anterior chamber depth. However, the two groups had statistical significance (P<0. 05) in the terms of age, dioptre before trement, corneal curvature, and axial length basis. Logistic regression analysis showed that foundation axial length, age and corneal curvature were in line with regression model ( P<0. 05 ), these were independent factors that orthokeratology lens control juvenile myopia development.
? CONCLUSlON: lndependent factors affecting orthokeratology control juvenile myopia development is foundation axial length, age and corneal curvature. For juvenile patients, the longer of foundation axial length, the longer the age, the greater the curvature of cornea, orthokeratology can better control the myopia’s development.

Objective To explore the relationships of serum leptin(LP),tumor necrosis factor-?(TNF-?)and insulin resistance in simple obesity children.Methods Forty-seven children with simple obesity were divided into two groups: high insulin group(HIG) and normal insulin group(NIG) according to the levels of fasting state of serum insulin and glucose.The fasting state of serum insulin(FINS),LP,TNF-? and fasting blood glucose(FBG) were measured.The relationships of LP,TNF-? and insulin resistance index(HOMA-IR) were also analyzed.Results 1.The BMI,waist,hip,waist hip ratio(WHR),LP,TNF-?,HOMA-IR were obviously higher in the HIG than those in the NIG and NCG groups(Pa0.05).3.In the HIG group,the FINS was positively correlated to LP,TNF-? and HOMA-IR(r=0.560,0.413,0.864 P

Background:Conventional treatment has limited efficacy in relapsed/refractory B-cell lymphoma.Since chimeric antigen receptor Tcell (CAR-T) technology has shown high safety and results in high remission rates,we investigated its efficacy and safety in B-cell lymphoma treatment and analyzed potential affecting factors to provide evidence for therapeutic strategies and applications.Methods:We searched databases including PubMed,Embase,and Cochrane up to July 2019.Meta-analysis 1 was conducted to study the efficacy of CAR-T cell for treating B-cell lymphoma,measuring the response rate and complete remission rate as outcomes.Sub-group analysis was performed for age,pathological type,target antigen,co-stimulatory molecule,and conditioning chemotherapy.Meta-analysis 2 was undertaken on the safety of the treatment with the incidence rate of toxicity (cytokine-releasing syndrome [CRS],neurotoxicity) as an outcome.Results:Seventeen studies were included in the systematic review and meta-analysis.It was found that CAR-T cells had good therapeutic effects in the following cases:B-cell lymphoma (patients ≥65 years old);diffuse large B-cell lymphoma pathological type;patients with treatment target antigen other than CD 19;patients treated with co-stimulatory molecules other than CD28,including 4-1BB+CD28 or 4-1BB;and patients treated with cyclophosphamide/fludarabine pre-treatment protocol conditioning chemotherapy.Although the CRS and neurotoxicity incidences were high,most were reversible with minimal risk of death.Conclusion:CAR-T cell treatment is safe for clinical annlication:however,toxicity effects should be monitored.

OBJECTIVETo explore the diagnosis and treatment of veno-occlusive priapism.

METHODSThe diagnosis and treatment of 17 cases of veno-occlusive priapism were analyzed retrospectively.

RESULTSAll the 17 patients were evaluated by physical examination, cavernous blood gas analysis and color Doppler ultrasonography, and treated by conservative therapy, intracavernosal aspiration and injection, surgical operation. After treatment, 11 cases achieved complete detumescence, 5 cases partial detumescence and 1 case of penile cancer failed to respond. During the 2-6 months follow-up, erectile dysfunction occurred in 3 cases.

CONCLUSIONCavernous blood gas analysis and color Doppler ultrasonography are helpful to the diagnosis of veno-occlusive priapism. Early and correct intracavernosal injection and corpora cavernosa-corpus spongiosum shunt are effective ways to treat veno-occlusive priapism.

OBJECTIVETo investigate the causes and influencing factors of heterogeneity of HSA/IL1ra fusion protein expression in Pichia pastoris.

METHODSThe heterogeneity of HSA/IL1ra fusion protein expressed in Pichia pastoris was studied by removing glycosylation and inhibiting glycosylation, as well as by different ways of fusion, different clones, and different expression host.

RESULTGlycosylation caused expression heterogeneity of fusion protein, but in SMD1168 and some GS115 clones there was no this phenomenon.

CONCLUSIONThe expression heterogeneity of HSA/IL1ra fusion protein in Pichia pastoris is due to the glycosylation, and different ways of fusion, different clones, different expression host also have some impact.

Objective To explore a kind of simple and high efficient approach to differentiate human embryonic stem cells(hESCs)into neural stem cells(NSCs).Methods hESCs were cultured in bacterial culture dish filled with serum free medium to gain embryoid bodies.Then the mature embryoid bodies grew in the special medium including B27 and noggin by adherent culture to differentiate into NSCs. Results The hESCs kept floating in the bacterial culture dish and growing all the time and then formed mature embryoid bodies 7 to 10 days later.The embryoid bodies could be differentiated into highly pure (96.4%)nestin positive cells.And these cells were differentiated into all kinds of neural cells if cultured further.Conclusions This kind of method is less time-consuming,cheaper,and more efficient than those of the results in literatures reported.It affords very good source of seed cells for cell transplantation therapy in the future.

OBJECTIVETo study the association of positive expression of nucleotide excision repair cross complementary group 1 (ERCC1) in the tumor tissues with platinum resistance of the tumor cells and the clinical outcomes of neo-adjuvant chemotherapy in elderly patients with non-small cell lung cancer (NSCLC).

METHODSERCC1 expression was detected immunohistochemically in the tumor tissues from 113 elderly patients with NSCLC, of which 58 patients received platinum-containing neo-adjuvant chemotherapy, and the impact of ERCC1 expression on the outcomes of neo-adjuvant chemotherapy was analyzed.

RESULTSThe total positivity rate of ERCC1 expression was 35% in these patients. The positivity rates was significantly higher in the patients receiving neo-adjuvant chemotherapy than in the control group (46.7% vs 21.05%, χ² = 3.770, P = 0.048). In the 39 patients positive for ERCC1, the response rate to treatment was 53.85%, as compared to the rate of 51.35% in the 74 ERCC1-negative patients. After neoadjuvant chemotherapy, the median survival time (MST) was 53 months in ERCC1-negative patients, as compared to 37 months in the positive patients. The ERCC1-negative and ERCC1-postivie patients showed similar 3- and 5-year survival rates (48.3% vs 44.4%, χ² = 0.033, P = 0.856; 22.5% vs 18.5%, χ² = 0.096, P = 0.757). Multivariate COX regression analysis showed that ERCC1 expression level in the tumor tissue and TNM stages were independent factors that affected the prognosis of the patients (P < 0.05).

CONCLUSIONNeoadjuvant chemotherapy can induce ERCC1 expression in the tumor, and the objective response rate of neoadjuant chemotherapy can be low in NSCLC patients with high ERCC1 expression. ERCC1 expression is an independent factor affecting the prognosis of elderly patients with NSCLC receiving neoadjuant chemotherapy.

OBJECTIVETo investigate the effect of preoperative nutritional support in the management of patients with chronic radiation enteritis (CRE) with intestinal obstruction undergoing resectional surgery.

METHODSClinical data of 158 CRE patients undergoing diseased bowel resection from 2001 to 2011 were analyzed retrospectively. A total of 130 patients received preoperative nutritional support, including 28 patients with enteral nutrition support, 60 patients with total parenteral nutrition support, and 42 patients with combined nutritional support. The nutritional parameters, procedures, operation-related complications, and postoperative hospital stay were recorded.

RESULTSAfter aggressive nutritional support in 130 patients, patients nutritional index, such as serum prealbumin, transferrin, serum albumin improved significantly preoperatively, while the change of body mass index and hemoglobin was not significant. Compared to those without preoperative nutritional support, those who received preoperative nutritional support had lower stoma rate (31.5% vs. 53.6%, P=0.027), less postoperative infection rate (13.8% vs. 32.1%, P=0.019), shorter postoperative hospital stay [(14.1±7.3) d vs. (18.8±15.8) d, P=0.013). Enteral nutrition group had less postoperative infection rate (7.1% vs. 21.7%, P=0.017), lower stoma rate (28.6% vs. 48.3%, P=0.02), and shorter postoperative hospital stay [(15.5±9.6) d vs. (21.7±19.0) d, P=0.025) as compared to total parenteral nutrition group.

CONCLUSIONSPreoperative nutritional support can decrease the stoma rate, postoperative infection rate, and shorten hospital stay in CRE patients complicated with intestinal obstruction. If tolerated, enteral nutrition support should be chosen.
