Objective To investigate the effects of ultrashortwave (USW) diathermy and electrical stimulation (ES) used in combination with nerve growth factor (NGF) in the treatment of experimental sciatic nerve injury.Methods Sixty adult Wistar rats were randomly divided into a normal control group, a model group, an NGF group,a physiotherapy group and a combined treatment group. A model of sciatic nerve injury was established in the latter four groups. Beginning on the 2nd day after the operation, no treatment was given in the model group, NGF was injected in the NGF group, diathermy and ES were administrated to rats in the physiotherapy group, and the combined treatment group was treated with USW diathermy, EW and NGF. Function, electrophysiology and morphology were evaluated at the 2nd, 7th, 14th and 30th days after the operation Results The average sciatic nerve function index (SFI), nerve conduction velocity (NCV) and nerve regeneration in the NGF, physiotherapy and combined treatment groups were significantly better than in the model group, with those in the combined treatment group improved to the greatest extent. At the 30th day there was no significant difference between the combined treatment group and the normal control group in terms of SFI, NCV, axon regeneration or myelin sheath thickness. The number of myelinated nerve fibers and the average axon diameter in the combined treatment group and normal control group were significantly higher than those in the model, NGF or physiotherapy group. Conclusions With NGF injection, additional application of USW diathermy and ES may significantly enhance the regeneration of the sciatic nerve and aid functional recovery after injury.

Human adenovirus (HAdV) is one of the most important pathogens in infants and young children with acute respiratory infections and other diseases. This article reviews the literature on HAdV, including its molecular biological characteristics, detection and typing, and pathogenic mechanism, the clinical features and epidemiological characteristics of HAdV-related diseases, and the prevention and control of HAdV infections. So far, 67 types of HAdV have been identified, including recombinant variants discovered in recent years. The major epidemic strains that cause acute respiratory infections are HAdV-3 and HAdV-7, both of which belong to the subgroup B. HAdV often leads to acute respiratory infections, but it also causes diseases of other systems. HAdV-related diseases have similar clinical manifestations as those caused by other respiratory viruses, but often accompanied by gastrointestinal symptoms. The pathogenic mechanism of HAdV remains unclear, especially for the new recombinant variants, due to few studies on their association with diseases. Because there are no prospective, large randomized controlled trials of HAdV infections, the treatment of HAdV infections is controversial. Vaccine is the most effective measure to reduce respiratory HAdV infections, but it is still not commercially available.

BACKGROUND: Pillbugs have been proved to exert an effect on the proliferation and migration of vascular smooth muscle cells (VSMCs) through MTT assay and scratch assay, but the mechanisms are poorly understood. OBJECTIVE: To investigate the molecular mechanisms underlying pillbugs influencing osteopontin-induced VSMC migration and proliferation. METHODS: VSMCs from Sprague-Dawley rat thoraco-abdominal aorta were cultured in a common medium, and 3-5 generations of cells were selected. There were eight groups: control, osteopontin, pillbug water extract (0.5, 1.0, and 2.0 g/L) with osteopontin, and pillbug ethyl acetate extract (0.25, 0.5, and 1.0 g/L) with osteopontin groups. After 24 hours of culture, the expression levels of proliferating cell nuclear antigen (PCNA) and integrin kinase (ILK) were detected by western blot assay. RESULTS AND CONCLUSION: Pillbug water and ethyl acetate extracts both inhibited the expression of PCNA, especially when cultured in 0.5 g/L pillbug water extract (77.8% of the osteopontin group) and 1.0 g/L ethyl acetate extract (74.1% of the osteopontin group). 0.5 g/L pillbug water extract significantly downregulated ILK level induced by osteopontin, which was 81.4% of the osteopontin group, while pillbug ethyl acetate extract exposed no influence on ILK expression. These results reveal that pillbug water and ethyl acetate extracts both are able to inhibit osteopontin-induced VSMC proliferation, and the role of the pillbug water extract maybe associated with ILK protein pathway.

Objective To explore the relationship between H.pylori (HP) infection and the functional dyspepsia (FD) by 4-lead electrogastrography (EGG). Methods The data of the gastric electrical activity of 163 children with FD, includ-ing 103 children with HP infection (group A), 60 without HP infection (group B) and 22 healthy controls (group C) were mea-sured by 4-lead EGG, which included normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria per-centage (T%) and motilin uneven rhythm percentage (A%). EGG frequency and power examination included the main fre-quency (DF), the main power (DP) and postprandial/pre-prandial gastric electrical main power ratio (P/R). EGG data was compared between three groups. Results There was significant difference in pre-prandial and postprandial percentage of different slow wave frequency between group A and group B. There were no significant differences in pre-prandial and post-prandial changes of DF and DP between group A and group B. There was no significant difference in the pre-prandial and postprandial percentage change of different slow wave frequencies in 84 HP negative patients. But the significant change was found in pre-prandial and postprandial change of DF, DP and P/R. Conclusion The eradication of HP improved the gas-tric electrical activity and relieved the postprandial symptom in children with functional dyspepsia under HP infection.
