Objective To evaluate the levels of neutrophil gelatinase associated lipocalin (NGAL) in prediction of acute kidney injury (AKI) in children with burn. Methods Forty seven children with burn were selected in this study and thirty healthy children were enrolled as a control group. Levels of blood routine, urine routine, serum creatinine (Scr), serum NGAL (SNGAL), urine NGAL (UNGAL), blood urea nitrogen (BUN) and C-reactive protein (CRP) were measured. Receiver operating characteristic (ROC) curve were used to estimate the AKI diagnostic value of serum NGAL, urine NGAL and Scr. Results On the day of admission, serum NGAL and urine NGAL were significantly increased in patients with AKI , while Scr did not change significantly as compared with those in non-AKI patients and the healthy controls. In AKI group, serum NGAL and urine NGAL were positively correlated with WBC and CRP on the day of admission , and positively related with Scr on the seventh day. ROC analysis showed the AUC of serum NGAL, urine NGAL and Scr on admission were 0.737(95%CI: 0.653 ~ 0.779, P < 0.05), 0.772(95%CI: 0.632 ~ 0.793, P < 0.05), and 0.508(95%CI: 0.454~0.618, P < 0.05) respectively. The cut-off value of serum NGAL and urine NGAL were 318 μg/L (sensitivity of 72.8% and specificity of 81.6%) and 105 μg/L (sensitivity of 75.6% and specificity of 83.7%). Conclusions Elevation in levels of serum NGAL and urine NGAL occurs earlier than that in Scr level in children with burn. Both serum and urine NGAL level can be used as a biomarker for early prediction of AKI.

Objective To investigate the clinical risk factors ot endoscopic mucosal resection (EMR) for early colorectal cancer.Methods The clinical data of 140 patients with early colorectal cancer who received EMR at the Changzheng Hospital of Second Military Medical University from January 2005 to June 2012 were retrospectively analyzed.EMR was applied for patients with early colorectal cancer with diameter lesser than 20 mm (protrusive lesions) or 5 mm (depressed lesions).If the diameter of the early colorectal cancer was above 3 cm and can not be resected at one time,endoscopic piecemeal mucosal resection was adopted.Clinicopathological factors including gender,age,tumor location,number,diameter,shape,resection type,depth of tumor invasion,tissue differentiation,lymphatic or vascular invasion,excision degree and curability were retrospectively analyzed.All the patients were divided into the complete cure group and the incomplete cure group.Univariate and multivariate analysis were done using the chi-square test and Logistic regression model,respectively.Results Of the 143 lesions,en-bloc resection was done in 125 lesions,and piecemeal resection in 18 lesions.There were 90 intramucosal carcinomas and 53 submucosal carcinomas.The numbers of high,moderate and low differentiated colorectal cancer were 96,37 and 10.Lymphatic or vascular invasion was found in 8 lesions.The numbers of R0,R1,R2 and Rx resection were 118,15,8 and 2.Two patients with Rx resection were excluded from this study.There were 98 patients (101 lesions) in the complete cure group,and 40 patients (40 lesions) in the incomplete cure group.The results of univariate analysis showed that tumor location,shape and resection type were the risk factors influencing the efficacy of EMR for early colorectal cancer (x2=7.523,16.280,4.156,P ＜0.05).The results of multivariate analysis showed that tumor located at the proximal colon,superficial protrusive and depressed type and piecemeal resection were the independently risk factors influencing the efficacy of EMR (OR =7.219,6.115,5.211,P ＜0.05).Conclusions EMR is not easy to achieve complete cure for early colorectal cancer with superficial protrusive and depressed type or located at the proximal colon.Endoscopic piecemeal mucosal resection should try to avoid.

AlM:To compare the efficacy and safety of latanoprost and brimonidine in the treatment of open angle glaucoma, and provide reference for rational drug use.METHODS:A total of 121 cases ( 136 eyes ) who were diagnosed as primary open angle glaucoma were selected in this study, and they were randomly divided into experimental group (62 cases, 70 eyes) and control group ( 59 cases, 66 eyes) according to different drug treatment. Patients in the control group received brimonidine eye drops twice a day, while patients in the experimental group received latanoprost eye drops once a day. The intraocular pressure, visual acuity and adverse reactions were checked of the two groups in the following 3mo.RESULTS:The intraocular pressure of patients in the control group was 18. 1 ± 1. 3mmHg, while the experimental group was 17. 0 ± 0. 9mmHg after 12wk of treatment, which were both lower than before (P<0. 05). The fluctuation of intraocular pressure in the experimental group was significantly lower than that of the control group. There was no significant difference in the LogMAR visual acuity between before and after treatment in the control group, while the LogMAR visual acuity of the experimental group was significantly improved. The control group had hyperemia, burning sensation, tearing, eyelid edema and other adverse side effects, and the experimental group had little adverse reactions. CONCLUSlON: Latanoprost can significantly reduce intraocular pressure in glaucoma patients with in the follow- up time, and reduce the impact of elevated intraocular pressure in the vision of glaucoma patients, with little adverse reaction, worthy of clinical application.

AIM: To investigate the efficiency of intravitreal ranibizumab therapy ( IVR ) for polypoidal choroidal vasculopathy ( PCV) in single or multiple polyps.
METHODS: A total 63 patients diagnosed with PCV in Shaoxing City People's Hospital from May 2013 to May 2015 were enrolled and divided into single polyp group and multiple polyps group. All patients received intravitreal ranibizumab 3 monthly and were followed up for 12mo. Observe the changes of best corrected visual acuity ( BCVA ) and central retinal thickness ( CRT ) at different time points.
RESULTS: The single polyps group exhibited a better BCVA, shorter greatest linear dimension, and lower prevalence of fibro - vascular pigment epithelial detachment compared with the multiple polyp group before treatment (P<0. 05). Significant difference of BCVA were observed at 3, 6 and 12mo between the two groups (P<0. 05). BCVA at 3, 6, 12mo was significantly better than that at baseline in single polyps group. The single polyp group exhibited a significantly thinner CRT at 6 and 12mo compared with multiple polyps group (P<0. 05). The single polyp group showed improvement in CRT over the followed up period(P<0. 05). The CRT in multiple polyps group at 3 and 6mo significantly decreased compared with preoperative (P<0. 05).
CONCLUSION: IVR meet better result in PCV patients with multiple polyp and polyp numbers may be valuable to prognosis.

Objective:To analyze the preliminary effects of subxiphoid video-assisted thoracoscopic extended thymectomy.Methods:We retrospectively analyzed the clinical data of six patients who underwent subxiphoid video-assisted thoracoscopic extended thymectomy in Peking University International Hospital from August 2018 to June 2020.Results:All six patients underwent successful subxiphoid video-assisted thoracoscopic extended thymectomy without conversion to thoracotomy. The rate of R0 resection was 100%. Operative time was (175.50 ± 67.78) minutes, intraoperative blood loss was (40.83 ± 31.37) mL, and postoperative drainage time was (7.17 ± 3.55) days. The total amount of postoperative drainage was (1781.67 ± 1293.53) mL. Postoperative hospital stay was (10.67 ± 6.35) days. The length of hospital stay was (19.67 ± 5.65) days. The Visual Analog Scale score measured after surgery was (2.12 ± 0.48) points. Three patients had grade 1 complications, with an incidence of complications of 50.00%. Grade 3-5 compilations did not occur in any patient. No patient died during the perioperative period.Conclusion:Subxiphoid video-assisted thoracoscopic extended thymectomy is safe and effective and provides a good visual field. The surgical method allows bilateral thoracic surgery, reduces surgical trauma, and has a broad application prospect.

The purpose of this study was to investigate the potential cardioprotection roles of Rapamycin in anoxia/reoxygenation (A/R) injury of cardiomyocytes through inducing autophagy, and the involvement of PI3k/Akt pathway. We employed simulated A/R of neonatal rat ventricular myocytes (NRVM) as an in vitro model of ischemial/reperfusion (I/R) injury to the heart. NRVM were pretreated with four different concentrations of Rapamycin (20, 50, 100, 150 μmol/L), and pretreated with 10 mmol/L 3-methyladenine (3MA) for inhibiting autophagy during A/R. Then, Western blot analysis was used to examine variation in the expression of LC3-II, LC3-I, Bim, caspase-3, p-PI3KI, PI3KI, p-Akt and Akt. In our model, Rapamycin had a preferential action on autophagy, increasing the expression of LC3-II/LC3-I, whereas decreasing the expression of Bim and caspase-3. Moreover, our results also demonstrated that Rapamycin inhibited the activation of p-PI3KI and enhanced the activation of p-Akt. It is concluded that Rapamycin has a cardioprotection effect by inducing autophagy in a concentration-dependent manner against apopotosis through PI3K/Akt signaling pathway during A/R in NRVM.

OBJECTIVETo study the safety and immunogenicity of the Bilive combined hepatitis A and B vaccine produced by Sinovac Biotech Co., Ltd.

METHODSSamples were selected from first year students of a senior high school (adults group) and first to fifth grade 1-5 students of 3 primary schools (children group). Those who were susceptible to both hepatitis A virus (HAV) and hepatitis B virus (HBV), HAV only or HBV only were assigned to group AB, A and B respectively and were vaccinated with three doses (0, 1 and 6 month schedule) of Bilive combined hepatitis A and B vaccine, inactivated hepatitis A vaccine and recombined hepatitis B vaccine respectively. The dosage for adult group was 500 U hepatitis A antigen and/or 10 micro g hepatitis B surface antigen and the dosage for children group was half the dosage of adult group. The potential adverse effects were observed within 72 hours after vaccination. Serum samples were collected for testing anti-HAV and anti-HBs at month 2 and 7 after the initial dose.

RESULTSThe rates of local adverse effects were 0.58% and 2.56% in children AB group and adults AB group and the general adverse effects rates were 9.88% and 5.45% respectively. Both local and general adverse effect rates were not significantly different to the control group. The sero-conversion rate of anti-HAV in children and adults AB group reached 100%, one month after 3 doses. The geometric mean titer (GMTs) reached 33,910 mIU/ml and 23,435 mIU/ml respectively, significant higher than that in control group (group A). The sero-conversion rates of anti-HBs were 97.30% and 96.63%, and GMTs were 103 mIU/ml and 102 mIU/ml in children and adults AB group respectively. No significant difference on sero-conversion and GMT was observed when compared with control group.

CONCLUSIONThe Bilive combined hepatitis A and B vaccine had good safety profile, and the immunogenicity both on anti-HAV and anti-HBs was similar to that of separated components.

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.
