Objective To observe the clinical effect of neonatal respiratory failure therapy with mechanical ventilation. Methods Forty - eight cases of neonatal respiratory failure were applied endotracheal intubation through mouth. At first, ventilation was given via the intermittent positive - pressure ventilation + peak end - expiratory pressure( IPPV + PEEP) way. Later, the breath parameters were regulated and transited to the intermittent mandatory ventilation( IMV) way according to original illness. When frac - tional concentration of in-spired gas(FiO2)

OBJECTIVETo investigate the effect of Wenjingtong Composita (WJTC) on blood glucose and advanced glycosylation end products (AGEs) in sciatic nerve of streptozotocin (STZ)-induced diabetic rats.

METHODSSTZ-induced diabetic rats were randomized to WJTC prevention group and WJTC treatment group. The levels of blood glucose and AGEs in sciatic nerve of the animals were checked after 12 weeks treatment and compared with that of aminoguanidine (AG) treatment group.

RESULTSBlood glucose level in the WJTC prevention and treatment group, and AGEs in sciatic nerve of the WJTC prevention group and the AG group were lower than those of the non-treated group (P < 0.01). Blood glucose level in the AG group was higher than that in the WJTC prevention group (P < 0.05), but was not significantly different from that in the non-treated group (P > 0.05).

CONCLUSIONWJTC might prevent diabetic peripheral neuropathy by decreasing blood glucose and inhibiting AGEs formation in sciatic nerve in STZ-induced diabetic rats.

Through arranging of ancient books and literatures related pressing moxibustion, the history along with origin and development of pressing moxibustion is systematically investigated and analyzed, which provided theoretical basis for the clinical practice of pressing moxibustion. It is found that after 600 years of development and innovation, pressing moxibustion already has complete theoretical system which is reflected in the unitarity of formulating prescription, the diversity of the manipulation the universality of indications. What's more, the functional characteristics and mechanism of pressing moxibustion are initially discussed and its present research status and prospect in the field of modern moxibustion are revealed.

Objective To observe the change of stanniocalcin 1 (STC1) and calcium content in brain of coal-burning-borne fluorosis rats,and to explore the role of STC1 in brain injury of coal-burning-borne fluorosis.Methods Twenty four male SD rats were randomly divided into control,low,medium,and high fluoride groups according to body mass.Control group was fed conventional rat chow(fluorinated 1.3 mg/kg),and low,medium and high fluoride groups fed with fluorinated feed(20.0,40.0,60.0 mg/kg).All rats were given distilled water and feed ad libitum.One hundred and eighty days after modeling,STC1 protein and gene expression in the brain tissue of rats were detected using immunohistochemistry and RT-PCR and calcium content of brain tissue was detected.Results The cell positive rates of STC1 in low,medium,high fluoride groups [(48.10 + 2.11)％,(54.90 ± 1.73)％,(79.30 ± 3.71)％] were significantly higher than that of the control group[(24.70 + 3.53)％,all P ＜ 0.05],the cell positive rate of high fluoride group was significantly higher than that of the low and medium fluoride groups (all P ＜ 0.05).The STC1 mRNA expression of low,medium and high fluoride groups (0.58 ± 0.09,0.85 ± 0.17,1.75 ± 0.04) were significantly higher than that in the control group(0.37 ± 0.12,all P＜ 0.05),the STC1 mRNA expressions of high fluoride group was significantly higher than that of the low and medium fluoride groups (all P ＜ 0.05).The brain cortex calcium ion concentrations of low,medium and high fluoride groups[(138.62 + 4.19),(167.43 + 6.57),(189.45 + 3.72)nmol/L] were significantly higher than that in the control group [(101.47 + 9.46)nmol/L,all P ＜ 0.05],the brain cortex calcium ion concentrations of high fluoride group was significantly higher than that of the low and medium fluoride groups(all P ＜ 0.05),and the medium fluoride groups was higher than the low groups (P ＜ 0.05).Conclusion STC 1 may be involved in brain damage of coal-burning-borne fluorosis rats through regulating calcium balance.

ObjectiveTo study the quality control methods for 99Tcm-TRODAT-1 kit and injection.MethodsThe appearance,pH,contents of the bases,the labeling yield,asepsis and bacterial endotoxins of 99Tcm-TRODAT-1 kits from three different batches were examined.The kit stability was estimated under different conditions.The transparence,pH,radiochemical purity,half-life,asepsis and bacterial endotoxins of 99Tcm-TRODAT-1 injection were tested.ResultsThe 99Tcm-TRODAT-1 kit and injection were both achromous and transparent,with pH values being 5.9 ± 0.1 and 5.5 - 7.0 respectively.The contents of stannous chloride and TRODAT-1 were stable.The labeling yield of the kit and the radiochemical purity of the injection were both ≥95％.The asepsis test demonstrated that the characters of 99Tcm-TRODAT-1 kit and injection were qualified.TRODAT-1 kit was stable at 0 -4 ℃ for 6 months or at room temperature (20 -25 ℃ )for 10 days,and the radiochemical purity of the injection was still ＞ 90％ at room temperature for 8 hours.ConclusionsThe quality control methods for 99Tcm-TRODAT-1 kit are simple and practical.The kit and injection are qualified and can be used for clinical application.

OBJECTIVETo investigate the epidemiological features of human calicivirus( HuCV) infection in children with diarrhea in a hospital in Guangzhou.

METHODSStool specimens were collected from children with viral diarrhea diagnosed between October, 2003 and January, 2004 and between October, 2004 and January, 2005. HuCV was detected by means of RT-PCR and sequence analysis of the PCR products.

RESULTSEighty specimens positive for Norwalk-like viruses (NLVs) were identified from 648 stool specimens, with a positivity rate of 12.35%, and sapporo-like viruses (SLVs) were identified in 2 specimens (0.31%). The monthly NLV positivity rate was 11.74% (Oct.), 14.16% (Nov.), 9. 09% (Dec.) and 13.95% (Jan.), respectively, showing no significant variation in these months. NLVs mainly infected children below 2 years old. Twenty-two strains of NLVs were sequenced and analyzed, and 21 of them were identified as GII and the genotype of 1 strain could not be determined. The prevalent viral population were GII-3 and GII-4 in 2003 and was GII-4 in 2004, and both of the SLVs belong to GI-1.

CONCLUSIONNLVs is one of the important pathogens causing sporadic acute gastroenteritis in children admitted in the hospital in Guangzhou, and the prevalent strains are GII-3 and GII-4 , but different prevalent strains are possible in different periods.

Lactobacillus casei 393 was selected as a bacterial carrier for the expression of Porcine Parvovirus (PPV) protective antigen VP2 protein. The gene encoding PPV VP2 protein was cloned into the Lactobacillus casei surface expression vector pPG, and then the constructed recombinant vector pPG-VP2 was electrotransformed into Lactobacillus casei 393 generating the recombinant system pPG-VP2/L. casei393 expressing PPV VP2 protein. The recombinant strain was induced by 2% Lactose in MRS and about 74kD protein was detected with SDS-PAGE. The result of Western-blot indicated that the expressed protein possessed the antigenic specificity which could be recognized by mouse anti-PPV serum. The indirect immunofluorescent test showed that the expressed protein was secreted on the cell surface Lactobacillus casei.
