Objective To evaluate the effects of connective tissue growth factor (CTGF) on corneal neovascularization.Methods Twenty-five Wistar rats were divided into control and experimental groups.Corneal neovascularization (CNV) was induced by alkaline burn of the cornea with 1 mmol/L NaOH.On the 1st,4th,7th,and 14th day,CNV was observed,and the expression of CTGF was investigated with immunohistochemical method in rat cornea at the different time point.Results On the 4th day,7th day and 14th day after alkaline burn,the areas of CNV were (12.740 ±2.536) mm2,(26.068 ± 10.028) mm2,and (37.588 ± 8.066) mm2,respectively.CTGF was rarely expressed in the cornea of normal rats,and then CTFG expression was quickly increased after alkaline burn,reached the highest level on the 4th day (1.714 ± 0.185),and then declined remarkably on the 7th day (1.334 ± 0.198).Conclusions CTGF might be involved in the formation process of corneal neovascularization after corneal alkali burn.

Objective To investigate MR findings and analysis of misdiagnosis of atypical invasive pituitary adenoma.Methods The MR findings of twenty cases of atypical invasive pituity adenomas confirmed by pathology were reviewed ,which were misdiag-nosed as chordomas or meningiomas.Results All the twenty cases showed iso-or slightly hypo-signal on T1 WI,iso-or slightly hy-per-signal on T2 WI;Enhanced scan displayed heterogeneous enhancement.The dynamic enhancement curve showed rapid enhance-ment phase.The bilateral cavernous sinuswere infringed in nine cases,in which the pituity and pituity stalk were not well seen. Among the twenty cases,twelve cases with suprasellar and anterior cranial fossa extension were misdiagnosed as meningiomas;eight cases with clival destruction were misdiagnosed as chordomas.Conclusion The MR features of atypical invasive pituity adenomas are various.In order to avoid misdiagnosis,a comprehensive analysis should be based on a variety of signs.

BACKGROUND:In dynamic hip screw fixation for treating aged osteoporotic intertrochanteric fracture, avoiding the loss of bone mass, or by other means that can increase the fixed screw pulout strength, wil improve the therapeutic effect of dynamic hip screw fixation. OBJECTIVE: To compare the effects of three kinds of repair methods on aged osteoporotic intertrochanteric fracture. METHODS:Data of aged osteoporosis intertrochanteric fracture patients, who received conventional dynamic hip screw fixation, bone cement augmentation with dynamic hip screw fixation and bone grafting with dynamic hip screw fixation, were retrospectively analyzed. They were divided into control group, bone cement group and bone grafting group. RESULTS AND CONCLUSION:After two years of folow-up, the excelent and good rates of Harris hip function were 95%, 80% and 70% in the bone grafting, bone cement and control groups, respectively. The healing time of fractures was significantly shortened in the bone grafting group (P < 0.05). The failure of screw fixation was similar between the bone grafting and bone cement groups. Screw withdrawing appeared in the control group. Results suggest that compared with conventional dynamic hip screw fixation and bone cement augmentation with dynamic hip screw fixation, the therapeutic effect and safety of bone grafting in nail path with dynamic hip screw fixation were better.

Objective To investigate the feature and the safety of birth process of induced labor by Propess.Methods The 380 cases of vaginal delivery women in our hospital between Sep.2006 to Dec.2007 who, were primigravida,term delivery,singleton gestation,vertex presentations and no standing contraindication, was considered as study group. The other 380 cases of women of labor spontaneous or intravenous oxyvenous in the same condition was considered as control group.The birth process,the amount of bleeding,the number of urine retention,and the prognosis of neonate were compared between the two group.Results The active phase and the second stage was abbreviated in the study group,(P0.05).Conclusion Propess was more effective and safe in shortening the active phase, the secona stage and reducing complications.

Objective:To study the use of three-dimensional computer reconstruction in diagnosis and treatment of hilar cholangiocarcinoma.Methods:A retrospective analysis of clinical data was conducted on patients with hilar cholangiocarcinoma admitted to the Department of General Surgery, the First Affiliated Hospital of the University of Science and Technology of China from January 1, 2017 to July 31, 2019. The classification of hilar cholangiocarcinoma, vascular invasion and surgical resectability were determined by preoperative three-dimensional reconstruction. These data were then compared with the findings obtained during operations, by comparing with the three-dimensional reconstruction technology findings in classification of hilar cholangiocarcinoma, vascular invasion, and hilar extent of biliary and vasculature involvement.Results:Of 65 patients included in this study, there were 35 males and 30 females, with an age of (60.35±10.70) years. After operation, these 65 patients were classified into type I ( n=7), type II ( n=4), type III ( n=14), and type IV ( n=40) using the Bismuth classification. The accuracy rates of preoperative three-dimensional reconstruction for hilar cholangiocarcinoma classification, portal vein invasion, hepatic artery invasion, and diagnosis of hilar cholangiocarcinoma vasculature involvement were 90.7% (59/65), 90.7% (59/65), 86.1% (56/65) and 80.0% (52/65) respectively. Conclusions:The three-dimensional computer reconstruction technology could visually and accurately display the shape and spatial extent of hilar cholangiocarcinoma. It has an important clinical use in accurately diagnosing hilar cholangiocarcinoma preoperatively.

Objective To evaluate the performance of Carba NP test (CNP) for detection of carbapenemases in carbapenem-non-susceptive Enterobacteriaceae.Methods Carbapenemases in Enterobacteriaceae strains isolated from clinical specimens in the 117th hospital of PLA from January 2010 to December 2014 were detected by both CNP and modified Hodge test (MHT),and corresponding results were analyzed and compared by Chi-square using SPSS version 19.0.Data acquired from PCR were used as the standard.Results Of the 253 carbapenem-non-susceptive Enterobacteriaceae strains,188 positive strains and 65 negative strains were detected by MHT,and 175 positive strains,77 negative strains and 1 undetectable strain were detected by CNP,while 177 positive strains and 76 negative strains were detected by PCR.Sensitivities of two tests were comparable [CNP,98.9％ (175/177),versus MHT,98.3％ (174/177);x2 =0.5,P =0.48],but CNP was more specific [100.0％ (76/76) versus 81.6％ (62/76);x2 =12.1,P ＜ 0.05].Positive result in the CNP was emerged earliest in a KPC-producing strain.Conclusion The CNP is rapid and simple,which have good sensitivity and specificity.Yet further perfection is still needed in the future.
