Objective To compare the effectiveness of two-suppression therapy with over-plus hyperopia lens and atropine mydriasis for school-age chihtren with monocular amblyopia. Method One hundred and sixty-seven cases of children with monocular amblyopia in the age of 7-12 years old were observed, who were randomly divided into two groups, using over-plus hyperopia lens or atropine mydriasis to suppress the normal eye, and the amblyopia eye was comprehensive trained, followed-up of 3 years. Results The effect rate was similar between over-plus hyperopia lens and atropine mydriasis [90.7%(78/86) and 91.4%(74/81), respectively]. There was no significant difference (P>0.05). Conclusions For school-age children with monocular amblyopia, you can use over-plus hyperopia lens inhibit the normal eye sight, its effect is similar with the atropine mydriasis.

Objective To evaluate the predictive value of cord blood bilirubin levels for subsequent neonatal hyperbilirubinemia in term infants with ABO hemolytic disease.Methods A total of 292 term newborns with ABO hemolytic disease admitted from August 1,2011 to July 31,2012 were enrolled.Cord blood bilirubin levels were analyzed and the clinical characteristics of the neonatal hyperbilirubinemia group (n=34) and non-hyperbilirubinemia group (n=258) were compared.A receiver operating characteristic (ROC) curve analysis was performed to identify the predictive value of the occurrence and cut-off point of hyperbilirubinemia in term infants with ABO hemolytic disease.Paired-t-test,Chi-square test and Spearman correlation were used for statistical analysis.Results Of the 292 term infants with ABO hemolytic disease,34 cases had hyperbilirubinemia,with an incidence of 11.6％.Cord blood bilirubin levels were significantly associated with the presence of hyperbilirubinemia.The mean cord blood bilirubin level in infants who developed hyperbilirubinemia was (52.4± 13.2) μ mol/L,and was (35.0±8.0) μ mol/L for those who did not develop hyperbilirubinemia (t=7.540,P=-0.001).When cord blood bilirubin concentration increased,the incidence of hyperbilirubinemia gradually increased (x2=113.715,P＜0.001; rs=7.19,P＜0.001).The ROC area under the curve of 0.882 (standard error 0.005,95％CI:0.873-0.891,P＜0.001) was significant in predicting neonatal hyperbilirubinemia by cord blood bilirubin,and the occurrence of hyperbilirubinemia increased with increasing cord blood bilirubin level.Neonatal cord blood total bilirubin ≥ 50 μ mol/L predicted hyperbilirubinemia,and the positive predictive value was 0.683,negative predictive value was 0.959,sensitivity was 0.690 and specificity was 0.958.Conclusions Cord blood bilirubin level is useful in predicting subsequent neonatal hyperbilirubinemia in term infants with ABO hemolytic disease.

Objective: According to clinical investigation, analysis on the storage format of DICOM3.0 medical images files and displaying them is the basis of medical image processing. It is very important for medical imaging technology. Methods: Firstly, with the DICOM standard, the format of the medical images is studied, mostly the format of the information header and data element. Then the DIB display of the DICOM images in Windows platform is put forward, using linear window-transformation. Results: It is successfully realized the display of CT、MR images. With the manual window-transformation, the displaying would be better. Conclusion: As the results show, the method studied in the paper can preferably realize the display of the DICOM medical images, meeting certain clinical needs, and laying a foundation for the following study.

Objective To discuss the methods of the prevention of the superior laryngeal nerveinjury at endoscopic thyroidectomy through subclaviclar approach.Methods The clinical data of 100 patients with thyroid diseases received endoscopic thyroidectomy through subclavicular approach were analyzed retrospectively.Nodular goiter in 69 cases,adenoma in 18 cases,simple goiter in 13 cases.Line side lobe resection in 35 cases,the side lobe subtotal in 8 cases,the side lobe resection + subtotal contralateral lobe in 48 cases,bilateral subtotal gland in 9 cases.Results All 100 patients after surgery pronounced normal,no tone deep,choking water,etc,patients 7-30 d laryngoscope review found no abnormalities.Conclusion Thyroidectomy through subclavicular approach under endoscope is calleidic thyroidectomy,effectively avoid permanent superior laryngeal nerve injury.

Objective To study the relationship between pathological, immunohistochemical and ultrastructural changes of skeletal myodystrophy (SMD) and the development of the disease.Methods SMD tissue of 20 cases were routinely processed,the paraffin sections,the semi thin sections and the ultrasthin sections were observed by light microscopy and electron microscopy.Results 20 cases with SMD tissue were divided into three groups: Simple SMD for 8 cases, major changes were regional; Progressive SMD for 10 ca ses, the pathological changes were diffuse with large amount of degeneration of cell organs; SMD derived from nerve injury for 2 cases, pathological changes of the part controlled by the nerve were observed. While SMD was injured, myosin got deneration first.Conclusion The pathological and ultrastructure changes could be used to judge the progressive degree of myodystrophin. The amount of lost myosin could forecast the progression of the disease.

Objective To evaluate the clinical value of 3D-FS-SPGR and 3D-reconstructional technique in detecting the lesion of articular cartilage of knee.Methods Fifty eight knees with OA(42 cases)or trauma (9 cases) in 54 cases (12 cases were confirmed by operation) were imaged with eight different MR imaging sequences including T 1-weighted,proton density-weighted,T 2-weighted FSE,STIR,3D-FS-SPGR,2D-FS-SPGR,3D-SPGR and 3D-FS-GRE.The classification and three-dimensional reconstruction of cartilage in four locations of knee were performed on different MR sequences.The detecting rate of cartilage lesion were calculated.The results in partly cases were analysed compared to operation. Results The detecting rate was different on each sequence as follow:T 1WI,GRE,STIR,PDWI,T 2WI and SPGR were 8.91%,16.36%,19.32%,19.57%,21.36% and 24.09% respectively (? 2=23.523,?

Mitogen activated protein kinase(MAPK) is one of the four biggest signal transduction systems which contain four subtribes named p38,ERK5/BMK1,ERK and JNK/SAPKrespectively.Previous studies have shown that MAPK pathway is involved in growth,cell differentiation,perishing,the synchronization of cell function and so on.p38MAPK,one of the members of MAPK family,plays an important role in the activation of inflammation-related cells to release inflammation mediator,modulating enzyme production as well as transferring factors activity in the process of chronic bronchitis(CB).This review focuses on multiple roles of p38MAPK in the pathogenesis and progression of CB.

Both molecular weight 6000 and 1000 polyethylene glycol (PEG) have been used to induce thc fusion of hepatoma cell by two methods of centrifugation and stillstand. The results showed that 50% PEG of molecular weight 1000 and centrifugation increase the percentage of fused cells. The procedure of cell fusion has been examined. The cytoplasm has been fused when the cells start fusing in one hour and a half, and the neucleus start fusing in two horus and a half.

The main progress in international critical care medicine in 2020 are: the reflections on the mandatory of implementation of the 1-hour cluster treatment strategy for sepsis are still continuing; the "metabolic resuscitation" therapy, represented by large dose of vitamin C, failed to yield positive results; the global epidemic of coronavirus disease 2019 (COVID-19) continues to spread, with evidences indicating Dexamethasone, Remdesivir or interferon β-1b (IFNβ-1b), Lopinavir/Ritonavir and ribavirin as promising therapy; conservative oxygen therapy did not exert positive effects neither for mechanical ventilated patients nor for acute respiratory distress syndrome (ARDS) patient; the concept of lung- and diaphragm-protective mechanical ventilation illuminates a new opportunity to potentially improve clinical outcomes for critically ill patients; there was no positive evidence for stress ulcer prophylaxis and timing of endoscopy for severe acute upper gastrointestinal bleeding; early initiation of renal-replacement therapy (RRT) for critically ill patients with acute kidney injury (AKI) has not shown positive effect. At last, artificial intelligence (AI) has shown good potential in identifying ARDS phenotypes and early predicting sepsis.
