Objective To explore the risk factors and seek effective intervention of intracranial hemorrhage in the premature in-fants .Methods Clinical data of the premature infants in our hospital from January 2009 to December 2013 was retrospectively ana-lysed and single factor analysis of 20 relevant factors was done for cases with intracerebral haemorrhage and without intracerebral haemorrhage .Logistic regression analysis were done for some influence factors of intracranial hemorrhage .Results 1 726 cases of premature babies were included in the study ,including 264 cases of intracranial hemorrhage .Logistic regression analysis results shown that the neonatal transport network and integrated active transport models are protective factors of intracranial hemorrhage in the premature infant .We found that basic-level hospital transport was an independent risk factor .Between January 2009 and De-cember 2011 ,142 of 714 premature infants were intracranial hemorrhage ,including 88 cases from 348 patients transported from bas-ic-level hospital ,the incidence of intracranial hemorrhage was 25 .29% ,and compared with the incidence of intracranial hemorrhage (14 .75% ) of our hospital ,the difference was statistically significant (P<0 .05) .From January 2012 ,we established perfect neonatal transport network and implementation of comprehensive active transport model .122 of 1 012 premature infants were intracranial hemorrhage ,including 75 cases of 490 patients from basic-level hospitals .The incidence was statistically significant different com-pared with the incidence of intracranial hemorrhage(9 .00% ) transported from our hospital(P<0 .05) .The incidence of intracranial hemorrhage in the premature infants transported from basic-level hospitals were statistically different before and after neonatal transport network and comprehensive active transport model was established (P<0 .01) .Conclusion It will effectively reduce the incidence of intracranial hemorrhage in the premature infant by establishing the perfect regional neonatal three-level network trans-port system and comprehensive active transport models .

Objective To observe enhancing effect of nerve regeneration on peripheral nerve defect models bridged by a new PRGD/PDLLA/VPA composite conduit.Methods In this study from February,2012 to March,2014,PRGD/PDLLA/VPA nerve conduits were tested in the rat sciatic nerve transection model.At different periods after operation,its ability to promote nerve regeneration was evaluated by sciatic functional index(SFI),electrophysiology (CMAPs,NCVs) and histologic assessment.Forty rats were randomly divided into 4 groups (n =10),group A:PRGD/PDLLA/VPA,group B:PDLLA/VPA,group C:PRGD/VPA and group D:autograft.Results At 12 weeks after surgery,the SFI value of group A (-45 ± 3.19)and group D (-42 ± 3.01)were significantly higher than those of group B(-79 ± 3.06) and group C(-72 ± 2.07)(P ＜ 0.05);The CMAPs of group A (24.89 ± 5.01) and group D (25.39 ± 5.63) were significantly higher than those of group B(14.88 ± 3.11) and C(15.00 ± 5.54);the NCVs of group A (31.42 ± 2.43) and group D (31.50 ± 2.16) were significantly higher than those of group B (20.11 ± 2.39) and group C(21.00 ± 2.13)(P ＜ 0.05).At 12 weeks after surgery,the numbers of regenerated nerve in the tube of group A (258 ± 6.18) and D(259 ± 5.59) were significantly higher than those of group B (231 ± 5.00) and group C(230 ± 5.07)(P ＜ 0.05).There was no significant difference between groups A and D(P ＞ 0.05).Conclusion These results illustrated that this new PRGD/PDLLA/VPA conduit could significantly facilitate the regeneration of short nerve defect and recovery of motor nerve,which provides a new thought for treatment of peripheral nerve injury.

It has been reported that metastasis-associated gene 1 (Mta1) is overexpressed in many malignant tumors with high metastatic potential. In addition, some studies indicated that MTA1 participated in invasion, metastasis, and survival of cancer cells by regulating cell migration, adhesion and proliferation. But the role of MTA1 is unclear in vitro in the development of cervical cancer cells. This study investigated whether and how MTA1 mediated cell proliferation, migration, invasion and adhesion in cervical cancer. MTA1 expression level was detected by Western blot in two cervical cancer cell lines of different invasion potentials. The effects of MTA1 expression on SiHa cell apoptosis, cycle, proliferation, migration, invasion and adhesion were tested by flow cytometry, MTT, wound-healing assay, Transwell assay and adhesion assay, respectively. The expression levels of p53, E-cadherin, and β-catenin activity were evaluated in untreated and treated cells. The results showed that MTA1 protein expression was significantly higher in SiHa than in HeLa, which was correlated well with the potential of migration and invasion in both cell lines. Furthermore, the cell invasion, migration and adhesion capabilities were decreased after inhibition of MTA1 expression mediated by Mta1-siRNA transfection in SiHa. However, no significant differences were found in cell apoptosis, cycle, and proliferation. In addition, E-cadherin and p53 protein levels were significantly up-regulated, while β-catenin was significantly down-regulated in SiHa transfected with the siRNA. These results demonstrated that MTA1 played an important role in the migration and invasion of cervical cancer cells. It was speculated that the decreased migration and invasion capability by inhibiting the MTA1 expression in the SiHa cell line may be mediated through the altered expression of p53, and E-cadherin/β-catenin complex. MTA1 could serve as a potential therapeutic target in cervical cancer.

Objective To investigate the CT and MRI findings of primary hepatic neuroendocrine carcinomas.Methods Imaging findings of 6 patients with pathologically confirmed hepatic neuroendocrine carcinomas were retrospectively analyzed.Four patients underwent plain CT and contrast enhanced CT examinations.The other 2 patients underwent plain MRI and contrast enhanced MRI.Results One out of the 6 cases manifested multicentric tumor which appeared as one large tumor surrounded with multiple small nodules peripherally,and the tumors of the other 5 cases were solitary.On plain CT images,all lesions were well-defined and hypoattenuating with central areas of even lower density except punctuate calcifications at tumor periphery in 1 case.On pre-contrast MRI,the cases manifested heterogeneous low signal intensity on T1 wI and slightly high intensity on T2 WI.On dynamic contrast enhanced CT and MRI,Tumors manifested slight to mild enhancement in arterial phase,slight enhancement in portal venous phase or delayed phase with no enhancement in the center,accompanied by dislocation of surrounding vessels.There Was no lymphadenopathy in peritoneal cavity and retroperitoniurm. Conclusion CT and MRI scanning can demonstrate specific features of primary hepatic neuroendocrine carcinoma,which may help the diagnosis and differential diagnosis of the tumor.

Objective To observe the efficacy of de novo combination therapy lamivudine plus adefovir , lamivudine monotherapy and entecavir monotherapy in HBeAg-positive CHB patients with genotype B/C. Methods A total of 182 treatment-naive CHB patients in line with treatment standards of Chinese CHB prevention and treatment guidelines were randomly assigned to three groups and treated with lamivudine plus adefovir or lamivudine monotherapy or entecavir monotherapy for 48 weeks. Results Patients in three groups presented no difference in baseline levels. After treatment by three therapies , the group of lamivudine plus adefovir showed a higher biochemical response rates (12 week P < 0.01, 24 week P < 0.01, 48 week P < 0.01), HBeAg-serological rates(12 week P < 0.01, 24 week P < 0.05, 48 week P < 0.05) and completely virological response rates (12 week P < 0.05, 24 week P < 0.05, 48 week P < 0.05) than lamivudine group. In terms of biochemical response rates , the group of lamivudine plus adefovir had certain advantages when compared with entecavir group. Conclusion De novo combination therapy lamivudine plus adefovir is a good antiviral strategy for chronic hepatitis B patients with B/C genotype viral infection in China.

Purpose To study the status of EGFR mutations and the expression of excision repair cross-complementation group 1 ( ER-CC1) and Ki-67 protein in patients with non-small cell lung cancer (NSCLC) and to examine the relationship between their expression and clinicopathologic features. Methods EGFR mutations were analyzed with DNA sequencing, and the expression of ERCC1 and Ki-67 protein was examined by immunohistochemistry EnVision. The relationship of EGFR mutations with the expression of ERCC1and Ki-67 and the clinicopathological features were analyzed. Results EGFR mutations were detected in 143 (143/291, 49. 1%) of the 291 specimens. EGFR mutations were found more frequently in women, non-smokers and adenocarcinoma. The difference of EGFR muta-tion rate between the histological subtypes according to the IASLC/ATS/ERS classification of lung adenocarcinoma was significantly ( P=0. 008). The mean tumor diameter was smaller in patients with EGFR mutations than in those with wild-type EGFR (P=0. 020). EGFR mutations were not related to age, lymph node metastasis. However, EGFR mutations were not related to the expression of ER-CC1 and Ki-67 protein (P>0. 050). Conclusions EGFR mutation is closely linked to several clinicopathological factors, such as gender, differentiation, and histological subtype. There is heterogeneity of EGFR mutation in patients with NSCLC. EGFR mutations were not related to the expression of ERCC1 and Ki-67 protein.

This study explored the possibility of using event-related potentials (ERP) for the measurement of picture-recognition memory and examined its correlation with the Chinese Wechsler Memory Scale-revised (WMS-RC) in patients with memory disorder caused by severe traumatic brain injury (sTBI). The subjects included 20 sTBI patients with memory disorder and 22 healthy individuals. Memory function was measured by using WMS-RC. Behavioral and ERP responses were recorded on-line during performance on a battery of picture recognition and the responses were analyzed off-line for recognition memory effects. Mean memory quotient (MQ) of patients with sTBI was significantly lower than that of the control group. Mean reaction time (RT) was significantly longer and the mean correctness rate (CR) of picture recognition was significantly lower in sTBI group than that of the controls. In controls, the main components of average ERP of picture recognition includes two positive-going waves, designated as P(170) and P(500), that appear 170 ms and 500 ms after stimulation when the subject could later successfully recall and recognize the pictures. P(500) amplitude of target stimulus was significantly higher than that of non-target stimulus. Compared to controls, P(500) responses of sTBI group were significantly delayed in latency (P<0.001) and lower in amplitude (P<0.001). P(500) latency showed significant negative correlation with MQ and the scores of "addition", "visual recognition", "picture recall", "visual reproduction" and "tactile memory" in WMS-RC. ERP of picture recognition provides a neurophysiological approach to directly assess memory impairment, and P(500) may serve as a helpful index for memory disorder caused by sTBI in forensic practice.

BACKGROUND: Hip-preserving treatment is advocated in the treatment of early avascular necrosis of the femoral head.OBJECTIVE: To compare the clinical efficacy of simple core decompression and three-dimensional porous core decompression combined with autologous bone marrow transplantation on early avascular necrosis of the femoral head.METHODS: Thirty patients (39 hips) with early avascular necrosis of the femoral head at phase I-II according to the staging criteria of the Association Research Circulation Osseuse (ARCO) who had been admitted to the First Affiliated Hospital of Luzhou Medical University between March 2011 and May 2016 were surgically treated and followed up.Seventeen patients (22 hips, trial group) were treated with three-dimensional porous core decompression combined with autologous bone marrow transplantation, including 10 cases of ARCO stage I and 12 cases of ARCO stage II; the other 13 patients (17 hips, control group) were treated with simple core decompression, including 7 cases of ARCO stage I and 10 cases of ARCO stage II. Harris scores, X-ray and magnetic resonance imaging were used to evaluate the surgical efficacy at 1, 3, 6, 9, 12, 18, 24, 30, 36 months after the operation.RESULTS AND CONCLUSION: The incision healed primarily in all patients, and no infection occurred. The follow-up lasted for 1-3 years (average 2.5 years). At the last follow-up, the Harris scores in both trial group and control group were significantly improved compared with the baseline (P < 0.05); moreover, the Harris scores of ARCO stage I and II patients were significantly higher in the trial group than the control group (P < 0.05). Collapse of the femoral head was observed in one hip (stage I) and one hip (stage II) of the trial group, and in three hips (stage I) and five hips (stage II) of the control group, and then hip arthroplasty was performed. The number of the patients developing collapse of the femoral head in the trial group was significantly less than that in the control group (P < 0.05). Compared with simple core decompression, three-dimensional porous core decompression combined with autologous bone marrow transplantation is more adept to improve patient's function and delay disease progression in the treatment of ARCO stage I and II early avascular necrosis of the femoral head.
