Purpose To discuss the relationship between age of onset and the HPV types infection in cervical adenocarcinoma. Meth-ods This study included 120 specimens of cervical adenocarcinoma in Jiangxi Maternal and Child Health Hospital. The specimen blocks were sliced by sandwich method. DNA was amplified by SPF10-PCR method. DNA genotyping was used with LiPA method. All biopsy specimens had pathologic diagnosis. The HPV infection of cervical adenocarcinoma specimens was analyzed. Results 120 ade-nocarcinoma cases were included in this study. HPV positive rate was 77. 5% (93/120). HPV 18 was the most prevalent type, which took up 43. 01% (40/93) of the total HPV positive cases, as same as HPV 16, which took up 43. 01%(40/93) of the total HPV pos-itive cases. The average ages of HPV 16 and HPV 18 were 43. 41 and 41. 06 years old respectively, other HPV types were 46. 85 years old, which showed statistically difference (F=3. 58, P=0. 032). Conclusion HPV 18 and HPV 16 are two most prevalent HPV types in cervical adenocarcinoma. The cases of HPV 18 infection are younger than other HPV-types infection.

OBJECTIVE:To review the curative efficacy and safety of itopride vs. domperidone in the treatment of functional dyspepsia(FD). METHODS:Randomized controlled trails(RCTs)of itopride vs. domperidone in the treatment of FD were enrolled and retrieved from Cochrane Library,PubMed,EMBASE,SCI,CBM,CNKI,VIP and Wanfang Database. Other retrieval was carried out by hand. Methodological quality evaluation and meta-analysis of RCTs were carried out. RESULTS:Of total 18 RCTs enrolled,11 RCTs were graded B and 7 RCTs graded C. Itopride group were superior to domperidone group in respect of total response rate,the relief rate of nausea,abdominal distention,belching,vomiting,epigastric pain and sour regurgitation. There was no statistical significance. The incidence of ADR in itopride group was lower than in domperidone group. There was no statistical significance in difference between two groups. The relief rate of anorexia and early satiety in itopride group were superior to domperidone group. Statistical significance was noted in difference between two groups. CONCLUSION:Recent study shows itopride has better effect than domperidone on FD,which should be confirmed by high quality study.

Objective To explore the child pneumonia in infection circumstances of Coxsackie B virus(CVB), Cytomegalovirus(CMV),Epstein-Barr virus (EBV).Methods Indirect ELISA were used to detect the specific IgM antibody of CVB, CMV, EBV. Results The total positive rate,which suffer from the three kinds of viruses in 140 children wich pneumonias was 38.6%.The positive rates of the CVB- IgM, CMV- IgM, EBV- IgM were 24.3%,8.6%,6.5%.Conclusions CVB has the higher infection rate in the pneumonia, is one of the main causes in the infection of child pneumonia.CMV,EBV also has the certain infection rate, although the infection rate is not high, they can cause damage of many organs and systems .They should be watched out for and valued.

ObjectiveTo investigate the changes of non-linear dynamics characteristics of EEG of the patients with menopause depression under eyes closed state.MethodsEEG were recorded in 18 patients with menopause depression and 18 healthy volunteers under eyes closed state. Approximate entropy (ApEn) was calculated for all subjects.ResultsApEn of the menopause depression group at eyes closed state increased significantly compared with that of the healthy control group.ConclusionDynamic non-linear analysis is more appropriate for the study of mental functions changes of menopause depression.

ObjectiveTo investigate the changes of non-linear dynamics characteristics of EEG during picture memory masks, and the application of non-linear dynamic analysis for memory research.MethodsEEGs of 30 healthy old volunteers were recorded under the states of opened eyes and picture memory. Correlation dimension (D2) was calculated for all subjects.ResultsD2 increased significantly during memory tasks compared with the rest state with eyes opened (P<0.05). In different memory tasks, the complexity of mental functions and the regions involved in the memory task were different.ConclusionNon-linear analysis is appropriate for the study of functional changes and working mechanism of brain during memory.

Objective To establish rat model of small intestinal damage by administrating low dose of diclofenac in short-term and to observe the preventive effect on non steroidal anti-inflammatory drugs (NSAIDs) induced small intestinal damage by metronidazole and rabeprazole.Methods Sixty-four rats were randomly divided into control,model,metronidazole and rabeprazole groups with 16 each.The rats in four groups were then further separated into acute stage (T1) and subacute stage (T2) groups.The rats were lavaged with metronidazole (50 mg/kg) and rabeprazole (15 mg/kg) before modeling.The rats in control,model,metronidazole and rabeprazole groups were lavaged with 1ml of distilled water, 7.5 mg/kg diclofenac,50 mg/kg of metronidazole plus 7.5mg/kg of diclofenac,15 mg/kg of rabeprazole plus 7.5mg/kg of diclofenac twice a day,respectively.The rats in T1 group were sacrificed on day 1 and T2 group on day 5.Results Administration of diclofenac induced multiple lesions in the small intestine, such as obviously erythema,erosion,ulcer and cystoid expansion.The lesions in T2 of model group was more seriously than that in T1 group(P＜0.05).And the lesions in model group was also more seriously than that in metronidazole and rabeprazole groups (both T1 and T2 groups,P < 0.05).Serum concentration of NO in T1 of model group was obviously lower than that in control group (P＜0.05),but it was higher in T2 of model group compare to the control group (P＜0.05).There were no significant difference among metronidazole,rabeprazole and model groups in serum level of NO (P>0.05). Conclusions The lesions of small intestinal can be induced by administration of diclofenac.The serum level of NO presents a tendency with decrease before increase afterwards.The metronidazole or rabeprazole has preventive effect on small intestinal lesions.

Objective To investigate the impact of aging and weight bearing on cartilage endplate morphology and chondrocyte apoptosis in rats. Methods The bipedal rat model (n=45) was developed by forelimb amputation and special breeding methods. The normal rats of the same age served as the control group (n=40). When the rats became 3, 6, 9, and 12 months old, 8 rats randomly selected from each group were sacrificed and paraffin-embedded mid-sagittal sections of the L4-5 spine were obtained. Sections were stained with hematoxylin and eosin and the TUNEL procedure was performed. The numbers of apoptotic cells and viable cells in the cartilage endplates of the intervertebral discs were counted, the thickness of the cartilage endplate was measured and the degree of impairment of the cartilage endplate was evaluated. Results Apoptosis first appeared in the cartilage endplate, then increased with aging and resulted in a remarkable decrease in cell density. The apoptotic rate of chondrocytes within the cartilage endplate of the bipedal rat model group was significantly higher than the control group at the 6-month time point. A statistically significant difference was observed in the bipedal rat model group between the 6-month time point and 9-month time point (P<0.05). Correlation analyses indicated that there was a highly negative correlation between the number of the viable cells of the cartilage endplate and the degree of the cartilage endplate degeneration (r=-0.97, P<0.05). Compared with the naturally aged group, the bipedal rat model group experienced more severe degeneration in the structure of the cartilage endplate, more obvious thickening of the cartilage endplate's calcified layer, and more defects in the structure of the cartilage. Conclusions Besides aging, weight bearing is probably a key factor of the increase of chondrocyte apoptosis and the degeneration of vertebral cartilage endplate.

Objective:Toprepare poly-DL-lactide-poly (PELA) microspheres encapsulating recombinant tissue inhibitors of metalloproteinase-1 (TIMP-1) adenovirus, and to investigate their effects on the proliferation of hepatocellular carcinoma HepG2 cells. Methods: The microsphere was constructed by encapsulating recombinant adenovirus containing TIMP-1 in biodegradable PELA. The diameter of the microsphere, quantity of virus encapsulated, loading rate, and releasing kinetics were measured. HepG2 cells were infected with the microspheres; the infection efficiency was examined by fluorescent microscope; and the ultrastructure was observed by TEM. The expression of TIMP-1 mRNA in HepG2 cells was examined by semi-quantitative RT-PCR, and the proliferation of HepG2 cells was detected by MTT assay. Results: The microsphere encapsulating recombinant TIMP-1 adenovirus was successfully constructed, with its diameter, entrapment efficiency, and virus loading rate being 1.965, 60.0%, and 10.5×10~8/mg, respectively. About 60% of the viruses were released within 120 h, and the total releasing time was longer than 240 h. Infection with rAdTIMP-1 PELA microsphere efficiently induced TIMP-1 expression in HepG2 cells, and significantly inhibited the proliferation of HepG2 cells, with the inhibitory rate being 47%. Conclusion: PELA microsphere encapsulating recombinant TIMP-1 adenovirus can markedly inhibit the proliferation of HepG2 cells, which provides an experimental basis for the combining macromolecular chemistry and gene therapy for treatment of hepatocellular carcinoma.
