Pathological cardiac hypertrophy serves as a significant foundation for cardiac dysfunction and heart failure. Recently, growing evidence has revealed that microRNAs (miRNAs) play multiple roles in biological processes and participate in cardiovascular diseases. In the present research, we investigate the impact of miRNA-34c-5p on cardiac hypertrophy and the mechanism involved. The expression of miR-34c-5p was proved to be elevated in heart tissues from isoprenaline (ISO)-infused mice. ISO also promoted miR-34c-5p level in primary cultures of neonatal rat cardiomyocytes (NRCMs). Transfection with miR-34c-5p mimic enhanced cell surface area and expression levels of foetal-type genes atrial natriuretic factor (Anf) and β-myosin heavy chain (β-Mhc) in NRCMs. In contrast, treatment with miR-34c-5p inhibitor attenuated ISO-induced hypertrophic responses. Enforced expression of miR-34c-5p by tail intravenous injection of its agomir led to cardiac dysfunction and hypertrophy in mice, whereas inhibiting miR-34c-5p by specific antagomir could protect the animals against ISO-triggered hypertrophic abnormalities. Mechanistically, miR-34c-5p suppressed autophagic flux in cardiomyocytes, which contributed to the development of hypertrophy. Furthermore, the autophagy-related gene 4B (ATG4B) was identified as a direct target of miR-34c-5p, and miR-34c-5p was certified to interact with 3' untranslated region of Atg4b mRNA by dual-luciferase reporter assay. miR-34c-5p reduced the expression of ATG4B, thereby resulting in decreased autophagy activity and induction of hypertrophy. Inhibition of miR-34c-5p abolished the detrimental effects of ISO by restoring ATG4B and increasing autophagy. In conclusion, our findings illuminate that miR-34c-5p participates in ISO-induced cardiac hypertrophy, at least partly through suppressing ATG4B and autophagy. It suggests that regulation of miR-34c-5p may offer a new way for handling hypertrophy-related cardiac dysfunction.

Objective To study the anti-HCV-IgG antibody and serum HCV-RNA value in the diagnosis of hepatitis c.Methods From December 2015 to December 2006,76 patients with hepatitis C were enrolled in this study.All patients were tested for serum anti-HCV-IgG antibody and serum HCV-RNA,and the positive detection rate of hepatitis C was detected by two methods alone.Results 76 specimens of anti-HCV IgG antibody testing positive rate was 27.63％,the detection of serum HCV-RNA positive rate was 25.00％,the two kinds of joint detection positive rate was 22.37％,the three methods positive rate were relatively close,but there was no significant difference(P＞0.05).According to different loads interval differentiate HCV-RNA virus detection rate of rising,anti-HCV-IgG five interval were 60.00 ％,83.33 ％,100.00 ％,100.00 ％,100.00 ％.Conclusion The detection of single anti-HCV IgG antibody or serum HCV RNA in the diagnosis of hepatitis c have limitations,the joint detection can effectively reduce the missed diagnosis and improve positive rate and provide a reliable basis for clinical diagnosis of hepatitis C.

Objective To study the rehabilitation effects of the cochlear implants on prelingually deaf children with alba abnormality.Methods A retrospective analysis of the effects of CIs was conducted in the prelingually deaf children of 11 cases of the children with abnormal alba(the research group) and 18 cases of the children who had normal alba(the control group) at the First Affiliated Hospital of Fujian medical university.All the operations were completed by the same doctor.There were no obvious complications during and after the operation.The cochlear implants were turned on after one month and the prelingually deaf children with extremely severe bilateral sensorineural deafness were trained for speech at the rehabilitation centre.The assessment criteria of the categories of auditory performance(CAP) and speech intelligibility rate(SIR) were used.After six months and twelve months of the operation, the family members were followed who have direct contacts with the children.The evaluation of data between the research and the control groups was administered.Results In the research group, the average level of CAP after six months'' post-operation was 2.41±0.47.But in the control group, the average level was 3.28±0.45.In the research group, the average level of SIR after six months'' post-operation was 1.27±0.44.There were 3 children in the research group at level 2, but in the control group, the average level was 1.89±0.31.Two children in the control group were level 1 while the others were level 2.In the research group, the average level of CAP after twelve months'' post-operation was 4.00±0.43 while only one child at level 3.There was one child at level 5 in the research group, the rest were level 4.There was a statistically significant difference in the average level of the CAP after six months'' post-operation(t=4.983, P<0.05) and in the average level of the SIR after six months'' post-operation(t=4.371, P<0.05).There was no statistical difference in the average level of the CAP after twelve months'' post-operation(t=1.033, P>0.05) and in the average level of the SIR after twelve months'' post-operation(t=0.434, P>0.05).Conclusion There is no significant difference of the rehabilitation effects of post-operation between the prelingually deaf children with alba abnormality and those with normal alba.

Objective To investigate the relationship between the indexes change of lactate dehydrogenase(LDH),serum tumor associated material(BXTM),β2-microglobulin(β2-MG),C-reactive protein(CRP) and D-dimer(DD) with lymphoma cell bone marrow infiltration(BMI) degree in the patients with non-Hodgkin's lymphoma(NHL).Methods Seventy-four cases of initially treated NHL were retrospectively analyzed and divided into the bone marrow invasion group(BMI,26 cases),lymphoma cell leukemia group(LMCL,31 cases) and non-BMI group(N-BMI,17 cases).The related indexes levels in each group were detected.ROC curve was drawn and analyzed.Results The levels of LDH,β2-MG,CRP and DD levels in the BMI group and LMCL group were higher than those in the N-BMI group(P＜0.05).Based on the ROC curve analysis,the optimal diagnostic cut-off points of each index in BMI were determined.The CRP and LDH had good sensitivity(100.00 ％),specificity(80.00 ％-100.00 ％) and diagnostic accuracy(80.00 ％ 100.00％).In the LMCL group,the diagnostic accuracy of DD,BXTM and β2-MG was 63.30 ％-100.00％.Conclusion The changes of LDH,CRP,β2-MG and DD in the patients with NHL are consistent with the BMI severity of lymphoma cells,which has a good clinical value in staging,curative effect judgment and prognosis.

BACKGROUND:Neural stem cel transplantation provides an important way to treat sequela of traumatic brain injury, but the timing for treatment is inconclusive.
OBJECTIVE:To explore the clinical effect of neural stem cel transplantation in the treatment of sequela of traumatic brain injury and the choice of the best treatment time.
METHODS: Totaly 178 patients with sequela of traumatic brain injury who underwent neural stem cel transplantation were divided into three groups as per the timing for neural stem cel transplantation: group A (with 6 months after injury,n=60), group B (6-12 months after injury,n=59), and group C (over 12 months after injury,n=59). Improvement in clinical symptoms and scores on function independent measure (FIM) were recorded and compared in the three groups.
RESULTS AND CONCLUSION:The total effective rate of group A was significantly higher than that in groups B and C (P < 0.05). FIM scores were significantly improved in the three groups after cel transplantation (P < 0.05). At 3 months after the fourth transplantation, the FIM score in the group A was significantly higher than that in the other two groups, and the incidence of adverse reactions in the group A was significantly lower than that in the other two groups (P < 0.05). These findings indicate that neural stem cel transplantation at different timing can al harvest certain clinical effects, but the best timing for neural stem cel transplantation is within 6 months after injury.

Objective To investigate the expression of Beclin1,p62 and Atg5 in serous ovarian cancer and its clinical significance.Methods The expression of Beclin1,p62 and Atg5 was detected in 50 serous ovarian cancer tissues by immunohistochemical method,and the relationship between their expression levels and the clinical parameters of serous ovarian cancer patients were analyzed.Results The expression of Beclin1 and Atg5 in serous ovarian cancer tissue was significantly lower than that in normal ovarian tissue,but p62 was significantly higher than that in normal ovarian tissue,and the difference had statistically significance (P＜0.05).The expression of Beclin1 and Atg5 were correlated with degree of cell differentiation and clinical stage (P＜0.05),while the expression of p62 was associated with clinical stages and lymph node metastasis (P＜0.05).Conclusions The abnormal expression of Beclin1,p62,Atg5 in serous ovarian cancer,which can lead to reduced autophagy body formation and autophagy activity,may be involved in the occurrence and development of serous ovarian cancer.

OBJECTIVE: To investigate imaging and audiology features of temporal bone and analyze the classification and prevalence of inner ear abnormalities in children with sensorineural hearing loss. METHOD: Children who were diagnosed with sensorineural hearing loss were examined by high resolution CT and the inner ear fluid of MRI. And each chart was retrospectively reviewed to determine the imaging and audiology features. RESULT: There were 125 patients(232 ears) found with inner ear malformation in 590 children with SNHL. About 21.71% of the inner ear malformation occurred in severe and profound hearing loss ears, and 12.85% occurred in r moderate hearing loss ears. The inner ear malformation rate in normal hearing ears were 13.59%. CONCLUSION CT and MRI examinations of temporal bone are important diagnostic tools to indentify inner ear malformations. Inner ear malformations are almost bilateral and hearing loss are profoud. Cochleo-vestibular malformations and large vestibular aqueduct are the 2 most frequent deformities. Among the children with SNHL, deformity rate in the severe and profound hearing loss ears is higher than that in moderate hearing loss ear. Inner ear malformations can exist in people with normal hearing.

BACKGROUND:In recent years, vacuum sealing drainage technology has been widely used in the treatment of orthopedic wounds or to facilitate skin graft survival, both of which have achieved good results.
OBJECTIVE:To observe the curative effects of vacuum sealing drainage technology in the wound healing after limb open fractures, soft tissue defects, pressure sores, and chronic osteomyelitis.
METHODS:Fifty-four patients of fractures combined with soft tissue defects, postoperative exposed bone, osteomyelitis, a large area of pressure ulcers or severe infections, selected from the 273rd Hospital of PLA, were randomly divided into test and control groups according to the wishes of patients. The test group included 36 patients who were treated with vacuum sealing drainage using polyethylene ethanol hydration seaweed salt after debridement, and the control group included 18 patients who were treated with conventional dressing. Wound cleaning time, number of dressings, and wound healing time were detected and compared in the two groups.
RESULTS AND CONCLUSION:Compared with the control group, the wound cleaning time and wound healing time were shorter in the test group, and the number of dressings was also decreased in the test group (P<0.05). After removal of sponge dressings, in the test group, wound granulation was fresh and grew obviously with no exudates after the necrotic residue was removed and vacuum sealing drainage was changed. For the bone exposure patients, the wound area was reduced, or even there was no exposed bone any more. After skin grafting, vacuum suction and pressure due to vacuum sealing drainage technology made al skin grafts survive. In the patients with chronic osteomyelitis, the exudates were gradual y reduced until disappeared after vacuum sealing drainage was exchanged three or four times, and pathogens were not found in bacterial culture. After combined treatment of debridement and vacuum sealing drainage, there were many fresh granulations in the patients with large areas of pressure sores;after replacement of vacuum sealing drainage several times, the granulation grew to the same height with the surrounding skin.
