ABSTRACT
Objective To comparatively analyze Toxoplasma gondii separated from HIV-positive people and RH strain GRA6 gene. Methods By using the nested PCR the amplification of Dali HIV-positive blood samples and RH strains of Toxo-plasma GRA6 genome was performed. The GRA6 gene amplification positive product was selected and the electrophoresis imag-ing was performed by being digested with the Mse I endonuclease and the gene sequences were measured and analyzed. Re-sults The GRA6 gene fragment 800 bp was successfully amplified and about 600 bp and 200 bp bands were got by Mse I. The sequencing results showed that T. gondii GRA6 gene positive samples had 2 nucleotide variation compared with T. gondii strain RH namely 447 base pair at C becoming G and 623 base pair at G becoming T. At 146 bp and 690 bp the Mse I restric-tion sites TTAA were found. Conclusion The preliminary judgment shows that the Dali HIV-positive T. gondii genotype is consistent with RH strain belonging to genotype I.
ABSTRACT
Toxoplasma gondii is an intracellular protozoan parasite that infects all warm?blooded animals. The surface anti?gens of T. gondii with the potential for application as antigens of diagnosis and vaccines have been studied extensively in recent years especially for P43 P35 P30 P23 and P22. The studies on the surface antigen in tachyzoites of T. gondii are reviewed in this paper.
ABSTRACT
This study was aimed to objectively evaluate the validity and safety of normalized Tuina massage thera-py on the treatment of 240 infants with acute diarrhea, thus disseminate and promote the application of infantile Tuina massage therapy. This study is a multicenter, randomized, controlled trial of 240 cases with acute infantile diarrhea. The experimental group (180 cases) was treated with Tuina massage therapy. The main acupoints are Pi-jing, Da-chang, Lan-men. And the combining acupoint is San-guan. In the control group (60 cases), the pa-tients were orally administered with Smecta. The statistical analysis was conducted with SPSS 15.0. The compre-hensive curative effect, time point effect, safety and technical stability of infantile Tuina massage were evaluated in the treatment of acute diarrhea. The results showed that the comprehensive effect of cure rate in the experi-mental group was 75.6% (136/180), and that of the control group was 21.7% (13/60). It showed that the effect in the experimental group was significantly better than the control group (P 0 . 05 ) . Furthermore , there was no side effect in both groups. It was concluded that the infantile massage technique is an effective therapy for the treatment of acute diarrhea . Meanwhile , it is a safe and stable therapy and is worth popularizing .
ABSTRACT
<p><b>OBJECTIVE</b>To reveal the relationship between iodine nutrition and the change of spectrum on thyroid diseases through comparing the different iodine environments pre- and post- the universal salt iodization(USI)campaign.</p><p><b>METHODS</b>To compare the urinary iodine concentration between 1000 normal people and 5998 patients with thyroid disease who had undergone surgical operations, from 4 major cities, including iodine deficient and rich areas of Guangxi Zhuang Autonomous Region.</p><p><b>RESULTS</b>After USI was put into practice, the urinary iodine concentration of patients with thyroid appeared higher than those of normal people(324.3 µg/L vs. 238.5 µg/L, P < 0.05). The urinary iodine concentrations of nodular goiter,Graves disease, toxic nodular goiter, thyroid papillary carcinoma and Hashimoto's thyroiditis were higher than those before the USI was taken(263.8 µg/L vs. 69.75 µg/L, 289.7 µg/L vs. 228.3 µg/L, 346.8 µg/L vs. 268.4 µg/L, 350.3 µg/L vs. 316.2 µg/L and 378.5 µg/L vs. 305.8 µg/L). The proportions of toxic nodular goiter, thyroid papillary carcinoma and Hashimoto's thyroiditis appeared as 7.59% vs. 4.80%, 5.85% vs. 4.02% and 3.88% vs. 2.46%, all higher than those before the implementation of USI, except the nodular goiter which showed a reduction (63.56% vs. 69.75%).</p><p><b>CONCLUSION</b>The spectrum of thyroid diseases appeared an obvious change in Guangxi within the last 10-year implementation of USI. However, the excessive intake of iodine might serve as a risk factor for toxic nodular goiter, thyroid papillary carcinoma and Hashimoto's thyroiditis.</p>

<p><b>OBJECTIVE</b>To generalize the application of Tuina in treating infantile diseases and evaluate the validity and safety of Tuina.</p><p><b>METHODS</b>By a multicentre randomized controlled study, 240 patients were randomly divided into an observation group (n = 180) and a control group (n = 60). The observation group was treated by tonifying Pijing and clarifying Dachangjing, and Tuina on Lanmen, Qi, Fu Shangqijiegu, Guiwei and Zusanli (ST 36), etc. Banmen and Sanguan were used as the supplementary point according to the syndrome differentiation. The control group was treated by oral administration of Smecta. After 5 day treatments, Chinese syndrome score and the clinical effect were evaluated.</p><p><b>RESULTS</b>After the third and fifth treatment, the Chinese syndrome score of both groups descended obviously. The decline of the observation group was superior to that of the control group (all P < 0.01). The cured rate of 75.6% (136/180) in the observation group was better than 21.7% (13/60) in the control group (P < 0.001). The clinical cured rate of 95.0% (171/180) according to Chinese syndrome score in the observation group was better than 58.3% (35/60) in the control group (P < 0.001). There was no adverse reaction in both groups.</p><p><b>CONCLUSION</b>Infantile Tuina has a better therapeutic effect in the treatment of acute infantile diarrhea than oral administration of Smecta.</p>

Anti-apoptosis plays an important role in tumour formation and development. Survivin is a member of the inhibitor of apoptosis (IAP) family, which is a target for anti-cancer drug exploitation was replaced as development. We investigated the role of the homo dominant-negative mutant Survivin-T34A in suppressing human lung adenocarcinomas (A549). The anti-tumour activity of HSurvivinT34A plasmid was evaluated in the A549 cell line and nude mice bearing A549 subcutaneous tumours. Low-dose systemic administration was continuously used. The HSurvivinT34A plasmid (5 μg/one) complexed with a cationic liposome (DOTAP/Chol) signifi cantly inhibited tumour growth in our model. We observed microvessel density degradation by CD31 immunohistochemistry and apoptotic cell increase by TUNEL assay, PI staining and fl ow cytometric analysis in the treated group. The present fi ndings suggest that the HSurvivinT34A plasmid complexed with a cationic liposome may provide an effective approach to inhibit the growth of human lung adenocarcinomas in vitro and in vivo.
ABSTRACT
Objective To develop a new ambulance aid on airport rescue of pilot and solve the difficult problems on medical staff, which carry the wounded from high aircraft cabin to the ground. Methods The device owned QG 0.85 trailer chassis. On the basis of it, self-made manual flexible extension-jib, flexible extension ladders and safety board were designed. The safety board was used to fix wounded pilots to protect secondary injury of backbone and C-spine. Results The maximal speed of equipment was 80km/h and spreading time is 3～7min, operating time is 4min and lifting height is 6 000mm. Conclusion The ambulance aid can be used in the location of flight accident quickly and rescued the pilots rapidly, adapted to any type fighters and met the needs of medical support in flight.
