Neonatal brain damage including hypoxia-ischemia encephalopathy(HIE) and intracranial haemorrhage,may cause adverse neurodevelopmental outcome such as cerebral palsy.Earlier diagnosis is very important for the treatment of brain damage.This review is to elucidate the relationship between imaging changes(CT,MRI and ultrasonography) and prognostic assessment,thus provide reference for clinicians,the objective is focus on imaging changes of HIE and intracranial haemorrhages,which are 3 of the most frequently reported cases.

Objective To investigate the expression of immunohistochemistry of gastrin(GAS),somatostatin(SS),proliferating cell nuclear antigen(PCNA) and Fas-ligand(Fas-L) in the sinus ventriculi of children with pediatric gastritis and to explore the significance of their expression in the pathogenesis of pediatric chronic gastritis.Methods Fifty cases of the sinus ventriculi mucosa samples were enrolled in 3 groups:chronic gastritis,helicobacter pylori(Hp) positive(group A,n=20);chronic gastritis,Hp negative(group B,n=19);control group,normal sinus ventriculi mucosa,Hp negative(group C,n=11).Immunohistochemistry En Vision were carried out including GAS,SS,PCNA and Fas-L.Results In the expression of GAS and SS,the values of group A and B were comparatively higher than those of group C,but there was no significant difference among them in statistics.In the expression of PCNA,the value of group A was comparatively higher and that of group B.The value difference between 2 groups was significant(P=0.019);in the expression of Fas-L,no significant difference was found among these 3 groups.Conclusions Expressions of GAS and SS both increase in children with chronic gastritis and maybe the increase of GAS and SS play a role in the pathogenesis of pediatric chronic gastritis;Hp infection promotes the multiplication of the sinus ventriculi membrana mucosa epithelium cell in pediatric chronic gastritis.

Objective　To study the indication, contraindication and short-term clinical effects of stereotactic radiotherapy (X-knife) in lung cancer. Methods　A total of 56 cases (Treatment group) of lung cancer were treated with X-knife composing of the modern 3-D treatment planning system and the stereotactic body frame, and SL-75 accelerator. And another 53 cases only treated with routine external radiation served as the control. In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone. Results　The actually reexamination rate for 1, 3, 6, and 12 months after X-knife treatment in 78 focuses from 56 cases was 79.5% (62/78), 89.8% (70/78), 87.2% (68/78) and 78.2% (61/78) respectively. The focuses reappeared in 3 months after the treatment and the growth rates of focus in 3, 6, and 12 month after the treatment were 2.6% (2/78), 5.1% and 9% (7/78) respectively. There were 2 focuses received a second treatment with X-knife because no change after the first one. Both the 1-and 2-year survival rates of 36 cases of the primary lung cancer in the treatment group were higher than that of control group (89.1%, 53.9% and 77.4%, 39.6%). Conclusion　The stereotactic radiotherapy is of applicable and prospective in the treatment of lung cancer. The indications include: ①As a boost dose in case when primary focus is less than 5 cm after the first external radiotherapy may reduce the exposure of lung tissue to x-ray and the occurrence of radiation pneumonia; ②Treatment for the recurrence after radiotherapy and operation; ③Radical treatment for the metastatic focus less than 5 cm. Attention must be paid to when multiple treatment is carried on the volume of the focus, the Karnofsky scores and the general condition when stereotactic radiotherapy combined with X-knife for lung cancer.

BACKGROUNDRecent studies have indicated that many mutations in mitochondrial (mt) DNA NDI gene region are related to diabetes mellitus. In this study we explored the relationship between various mtDNA ND1 gene mutations and type 2 diabetes mellitus (DM) among Chinese.

METHODSUsing PCR restriction fragment length polymorphism (PCR-RFLP) analysis and gene sequencing, 4 spots of mtDNA (nt3243, nt3316, nt3394, nt3426) were screened in 478 diabetics and 430 non-diabetic subjects.

RESULTSIn diabetic group, there were 13 carriers (2.72%) of 3316 G-->A mutation,12 (2.51%) of 3394 T-->C mutation and 2 (0.42%) of 3426A-->G mutation. In controls, only 3394 T-->C mutation was observed in 2 subjects (0.47%). There was significant difference in the frequency of 3316 and 3394 mutation between two groups (P < 0.05, respectively). More subjects with mitochondrial DNA ND1 gene mutations had DM family history and greater tendency of maternal inheritance when compared to those patients without mutation in diabetic group (P < 0.01). A 3426 mutation diabetic pedigree was studied, and we found 12 maternal members in the family had the same mutation.

CONCLUSIONmtDNA ND1 gene mutations at nt3316 (G-->A), nt3394 (T-->C) and 3426 (A-->G) might contribute to the pathogenesis of DM with other genetic factors and environment factors.

OBJECTIVETo study the effect of Acanthopanax senticosus injection (ASI) on the activities of human tumor necrosis factor (TNF) and natural killer cell (NKC) in the patients with lung cancer and the underlying mechanism.

METHOD73 cases with lung cancer were randomly divided into two groups, namely, the treatment group (n = 39) and observation group (n = 34); 61 cases with or without other diseases were respectively divided into control A (n = 30) and B (n = 31) groups. The patients in treatment group were injected with ASI for 21 days. The activities of human TNF and NKC and the levels of IgG, IgA and IgM were detected respectively.

RESULTAfter injection with ASI the activity of TNF-alpha in treatment group was comparable with that in the two control groups and was significant lower that that in observation group. The activity of TNF-beta and the levels of IgA, IgG and IgM were significantly higher than those in observation group and two control groups (P < 0.01). The activity of NKC was also remarkably higher than observation and two control groups.

CONCLUSIONASI can regulate the cellular immunity and factor, indicating that ASI can be used as an assistant drug to regulate the function of cellular immunity in the patients with lung cancer.

OBJECTIVE: To explore the relation between changes in expression of aquaporin-4(AQP4) protein and acute radiation-induced cerebral edema after Gamma knife radiation. METHODS: The experimental model was established in rats by radiating 2 mm right to median line in cerebral hemisphere with 50 Gy Gamma knife (the center located at the line of auditory canal). The changes of brain water content were measured by the wet and dry weight method. Immunohistochemistry was used to determine the change of expression of AQP4 protein at different periods after Gamma knife radiation. RESULTS: The brain water content and the expression of AQP4 in the target area and the peripheral zone obviously increased at 12 h after Gamma knife radiation, and achieved the peak after 2 d. It was still higher than normal after 14 d. The gray value of expression of aquaporin-4 was negatively related to brain water content (r=-0.9857, P<0.05). CONCLUSION AQP4 has a close relationship with acute radiation-induced cerebral edema.
