Objective To study the role of local immunity in the female genital tract with non- gonococcal urethritis(NGU).Methods Forty-four cervical secretions from patients with NGU were collected.After treatment with Azithromycin,22 cases were followed up.One month later,pathogen was eliminated in 15 patients.Another 27 un-infected people were included in our study.The level of secretory immunoglobulin A(SIgA)was detected using the automatic special protein analysor,and interferon-?(IFN-?)was quantified by enzyme-linked immunosorbent assay(ELISA).All data were analyzed with ANOVA.Results The levels of SIgA and IFN-?in NGU infected group were(34.29?15.92)mg/L and(97.13?24.00)ng/L respectively,while those of uninfected group were(47.57?19.61)mg/L and(120.71?33.78)ng/L,respectively(all P0.05).Conclusions SIgA and IFN-?secreted by genital tract mucosa may help pre- vent and resist the local NGU infection.However,the effect is limited,and is insufficient to eliminate infection completely and prevent reinfection.

Objective　 To explore the feasibility of recombinant adeno-associated virus (rAAV) as a vector for the gene therapy of liver cancer. Methods　 The rAAV/enhance green fluorescein protein (EGFP) recombinant was prepared by the routine method of two plasmids cotransfection. Results　 The experiment showed that one 10cm plate could produce 107-108 infection unit recombinant by the method of two plasmids cotransfection, and the transduction of HepG2 cell was increased with the increase of infection dosage of rAAV. About 100 multiplicity of infection (MOI) AAV vector could make all the tumor cell light. Conclusion　 Liver cancer cell can be efficiently transduced by rAAV, and AAV vector may be a valuable vector for the gene therapy of liver cancer.

Objective Ritodrine hydrochloride(RH) combined with radix salviae mihiorrhisa(RSM) is ap- plied to treat fetal growth ristriction(FGR). Curative effect was recorded during observation. Methods 62 pregnant women with slowly growing fetuses were divided into two groups randomly. Group A(test group) :including 31 preg- nant women who received RH combined with RSM treatment. Group B(control group) :including the other 31 preg- nant women who only received RSM treatment. Group B received 250ml of fat emulsion injection. One time every three days within one week. At the same time,gronp B also received injection of 500ml 10 % dextrose, coenzyme A 100U ,ATP 40mg,vitamin C 2g,dextran-40 and compound salvia injection 10ml one time a day,ten days in all. Be- sides the above-mentioned medicament for group B, group A received RH 100ml injection every day. Ten days was a period of treatment. After the treatment, uterine height, abdominal circumference, weight were measured and bipari- etal diameter, head circumference, abdominal circumference were checked by B-type ultrasonic inspection. After birth,weight of the baby and weight of placenta were measured too. Results Measurement indexes from group A, weight of the new-born baby and weight of placenta are obviously higher than those from group B. Conclusion RH combined with RSM can obviously extend blood vessel, loose placenta, improve blood circulation, accelerate cell metabolism, make microeirculation better, reduce permeability of capillary vessel, keep placenta's function and help foetus' growth.

Objective To clone amastin coding genes from different strains of Leishmania parasites. Methods Using amastin cDNA sequence as the reference, dbEST data base established by National Center Biotechnology Information (NCBI), USA, was searched by BLAST tool. A 309 bp DNA fragment of Leishmania major was found and used as the probe for the screening of a DNA library. The amastin gene of Leishmania major Abdou was cloned and sequenced. Specific primers were designed and amastin genes for Leishmania mexicana WR972, Leishmania brizeliensis and Leishmania amazonensis joseph were amplified by polymerase chain reaction. Results The amastin genes from 4 strains of Leishmania parasites were cloned and sequenced. It was found that all 4 amastin genes contained unique open reading frame of 552 bp and encoded amastin protein of 183 amino acid residues. Conclusion The amastin genes of 4 strains of Leishmania parasites were successfully cloned.

Objective Study on the distribution of auto‐antibodies against platelet in adults and children with primary immune thrombocytopenia(ITP) .Methods Platelet auto‐antibodies were detected in 83 ITP patients and 58 non‐ITP patients by enzyme linked immunosorbent assay (PAKAUTO kit) .Anti‐GP Ⅱ b/Ⅲ a ,GP Ⅰ b/Ⅸ and GP Ⅰ a/Ⅱ a auto‐antibodies were analyzed for 46 a‐dults and 37 children with ITP .Results The positive rate of autoantibody was 66 .27% in ITP patients ,which was much higher than that of non‐ITP patients ,the difference was significant(P < 0 .05) .As for ITP patients ,female ITP patients in adult group were 28 ,while in children group were 24 ,the difference was not significant(P > 0 .05) ,but the morbidity of ITP in females was higher than that of males in both of the two groups ,the difference was significant(P< 0 .05) .There was no significant difference on the distribution of platelet auto‐antibodies in adult and children group(P> 0 .05) ,the main of them was resistance against GP Ⅱ b/Ⅲ a and GP Ⅰ b/Ⅸ antibodies .Conclusion The detection of platelet auto‐antibodies could distinguish ITP and non‐ITP patients ,and GP Ⅰ a/Ⅱ a has an important reference value about therapy .

Objective To investigate the distribution of complications and the relationship with neurologic subtype and gross motor function in preterm infants with cerebral palsy (CP). Methods The type, grade of Gross Motor Function Classification System (GMFCS), intelligence,speech, ophthalmologic consultation, brainstem auditory evoked potential and electroencephalogram of 135 preterm infants with CP were reviewed. Results There were 284 complications in total, (2.10±1.33) per child, and was significantly different among various types of CP (F=5.50, P<0.001). The incidence of mental retardation and speech disorder was significant different among various types (P<0.05). The incidence of mental retardation, speech disorder, visual impairment and epilepsy increased significantly (P<0.05) in spastic quadriplegia infants,compared with those with diplegia and hemiplegia. The incidence of mental retardation, speech disorder, visual impairment and musculoskeletal disorder was significantly different (P<0.05) among various grades of GMFCS. The frequency of complications was more in children unable to walk (GMFCS Ⅳ~Ⅴ) than able to walk (GMFCS Ⅰ~Ⅲ) for children over 2 years old (t=70.05, P<0.001). Conclusion The incidence of mental retardation, speech disorder, visual and hearing impairment, secondary musculoskeletal disorder and the multiple disorders are related with neurologic subtype and/or the grade of GMFCS.

Drug safety has always been a global focus. Discovery and accurate information acquisition of adverse drug reaction have been the most crucial concern. Terminology of adverse drug reaction makes adverse reaction medical report meaningful, standardized and accurate. This paper discussed the domestic use of the terminology WHOART and MedDRA in terms of content, structure, and application situation. It also analysed the differences between the two terminologies and discusses the future trend of application in our country

Objective To investigate the effects of osteogenic growth peptide (OGP) in combination with extracorporeal shock waves (ESWs) on osteoblast proliferation.Methods Passaged cells were divided into four groups for different treatments:a control group,an OGP + ESW group,an ESW group,and an OGP group.After the respective treatments,the cells were cultured for 24 h,48 h and 72 h and counted using methylthiazdy tetrazolium (MTT) and an inverted fluorescence microscope. Immunohistochemical examination was used for detecting protein kinase A (PKA)activity,and a reverse transcription-polymerase chair reaction (RT-PCR) was used for examining PKA mRNA expression at 24 and 48 hours.Results Cell counting revealed that cell proliferation in the OGP + ESW,ESW and OGP groups was significantly promoted compared with the control group.Cell proliferation was greatest in the OGP + ESW group.The immunohistochemical examination showed positive staining intensities in the OGP + ESW,ESW and OGP groups significantly higher than in the control group.The positive staining intensity in the OGP + ESW group was again the highest.PKA activity was also significantly higher in the OGP + ESW,ESW and OGP groups than in the control group with the level in the OGP + ESW group the highest.Conclusion OGP in combination with ESW has a synergistic effect in stimulating osteoblast proliferation and growth.
