Cultured human embryonal thymus graft was performed on 80 patients with allergic rhinitis to observe the immune function of the patients and the treatment efficiency. The thymus from the fetus of intermediate abortion was cultured for 7 to 10 days. The T cell subsets and serum antigen special IgE(sas IgE) level of the patients were determined before and after the thymus transplantation. The gross treatment efficiency is up to 92.4% among the trial patients after graft for 3 years and CD8 positive cells were increased with a significantly statistical difference (P＜0.01), and sas IgE level was much lower than before thymus transplantation (P＜0.01). It was concluded that the thymus transplantation might regulate the immune function of the patients with allergic rhinitis, including increases in the number and the function of Ts cells, and a decrease of IgE level.

Objective To explore the behavioral patterns of middle school students and provide basis for unintentional injury prevention in these students.Methods 171 injury students and 171 normal students as controls were evaluated by Youth Self-Report(YSR),and mean scores were compared between the two groups by t Test.Logistic regressions were performed to analyze the relationship between injury students and behavioral problems.Results The rate was higher in injury group(15.79%) than in control group(8.19%).The score of injury group of boys was higher than thar of control group(t=2.942,P=0.004);the score of injury group of girls was higher than thar in control group(t=3.766,P=0.000).Multi-factor Logistic regression analysis showed that attention-deficit(OR=5.376),the problem of thinking(OR=3.672),social problems(OR=2.204) and friendly fellows' action was a risk factor.Conclusions There is a significant effect of the behavior of students and fellow students on the injury to students.

The gene encoding thermostable lactate dehydrogenase (Tm-LDH) was cloned into the plasmid pHsh from Thermotoga maritima, and expressed in Escherichia coli JM 109. The recombinant protein was purified to homogeneity by a simple step, heat treatment. The recombinant enzyme had a molecular mass of 33 kDa. The optimal temperature and pH of Tm-LDH were observed 95 degrees C and 7.0. The purified enzyme had a half-life of 2 h at 90 degrees C, and exhibited better stability over a pH range from 5.5 to 8.0. The K(m) and V(max) values were 1.7 mmol/L, 3.8 x 10(4) U/mg of protein for pyruvate, and 7.2 mmol/L and 1.1 x 10(5) U/mg for NADH, respectively. The expression of Tm-LDH in T7 system could not obtain high efficiency, but it has been soluble over-expression in pHsh system and reached 340 mg/L. The superior stability and productivity of Tm-LDH will lay the foundation of its industrial-scale fermentation and application in the NAD regeneration.

Objective To observe the clinical effect of Ozagrel sodium with ultrasonic therapy in patients with acute cerebral infarction (ACI). Methods Eighty-three ACI patients were randomly divided into 2 groups: ultra-sortie therapy group(n=42) received Ozagrel sodium and ultrasonic therapy, whereas control group(n = 41) only ac-ecpted the Ozagrel sodium for injection. Both two groups were under conventional treatment. The level of laboratory in-dex and the neurological impairment were detected before and after treatment. And the clinical effect were detected in the end of the treatment. Results The neurological impairment and the clinical effect defected after therapy in both groups, had statistical difference(P < 0. 05), especially in the ultrasonic therapy group. Conclusion Ozagrel sodium with ultrasonic therapy in patients with ACI could promote recovery of the neurological function, thus increase clinical effect.

Objective To investigate the influence of comprehensive intervention on improving the quality of life of idiosyncratic infants and young children.Methods A control study Was conducted on 106 idiosyncratic patients aged 6 months to 1 year with specific genetic background,eczema and wheezing under allergen test and comprehensive intervention via a randomized double-blind method.The onset of symptoms and measurement of immunological function were compared after 18 months.Results Serum IgG and IgA increased(all P＜0.05),wheezing and eczema attacks decreased significantly(all P＜0.01),sleep and emotion also improved significantly in the treatment group after 18 months(all P＜0.05).Milk and eggs were the most common allergen for infants and young children.Conclusion Idiosyncrasy and environmental factors were risk factors for allergic diseases.Early childhood was a critical period influencing the occurrence of allergic diseases in children.Early intervention could reduce the incidence of allergic diseases in children and improve the quality of life of idiosyncratic infants and young children.

Objective To observe the clinical effect of multidisciplinary rehabilitation on diabetic foot.Methods98 diabetic foot patients were divided into the routine treatment group (50 cases), treated only with conventional treatment, and the multidisciplinary rehabilitation group (48 cases) added with multidisciplinary rehabilitation besides conventional treatment.ResultsAfter one month treatment, blood flow parameters of the patients with 0 grade diabetic foot in the multidisciplinary rehabilitation group were markedly improved showed by color Doppler ultrasonograghy of lower limbs ( P<0.05); after two months treatment, the effect of the multidisciplinary rehabilitation group was better than that of the routine treatment group ( P<0.05).ConclusionThe multidisciplinary rehabilitation has obvious effect on diabetic foot and can improve disease recovery earlier.

Systems-based integrated course is the core and hot spot in current advanced medical education reform.An integrated organ-system oriented curriculum system of endocrinology and metabolism was applied in eight year clinical medicine and five year excellent doctor education.The teaching contents of endocrinology and metabolism from traditional Basic Medicine,Internal Medicine and Surgery were integrated and optimized to compile the integrated syllabus and teaching cases.Curriculum integration oriented PBL teaching and comprehensive morphology experimental teaching were implemented into the integrated endocrinology and metabolism system curriculum.This endocrinology and metabolism course integration based on organ-system based learning is conducive to establishing the organic connection between Basic Medicine and Clinical Medicine,and cultivating high-quality medical talents.

Objective To explore the values of CT virtual gastroscopy (CTVG), three dimensional (3D) and axial imaging by multi slice spiral CT (MSCT) in the preoperative assessment of gastric carcinoma. Methods Fifty two patients with gastric carcinoma proven by means of biopsy underwent CTVG, 3D imaging using the surface shaded display (SSD) and Raysum, and axial imaging. MSCT was first performed after the ingestion of gas, and a second tri phase MSCT scan was performed after the ingestion of water. The results were compared with those of fibrous gastroscopy (FG) and surgical pathological findings. Results The detection rates of gastric lesions with CTVG, 3D and axial imaging by MSCT were 98.1%, 96.2%, and 96.2%, respectively. The accuracy of judging gross type of advanced gastric carcinoma using CTVG combined with 3D imaging, FG,and axial imaging was 92.5% , 82.5%, and 75.0%, respectively.Statistical difference existed in CTVG combined with 3D imaging and axial imaging (P

Objective To explore the clinical characteristics and surgical treatment of gastric cancer in elderly patients.Methods The clinical data of 431 patients older than 70 years with gastric cancer from 1984 to 1998 were analyzed retrospectively.Results The main clinical manifestations were upper abdominal pain,distension or upset,loss of appetite and weight.The patients with clinicalⅢ,Ⅳ stage accounted for 64.2 percent.Pathological findings showed no specificity.Radical gastrectomy was performed in 215 cases(49.9%),and palliative resection was done in 122 ones(28.3%).The operative mortality and postoperative complication rate were 5.1%and 25.5%in the patients respectively.The 5-year survival rate was 29.5%in the patients with surgery,53.2%with radical gastrectomy and 10.7%with palliative resection.There were significant differences in 5-year survival rate between the radical and palliative groups.Conclusions The majority of elderly patients are clinical Ⅲ,Ⅳ stages and their operative complication rate is high.The key to increase the survival rate and life quality of elderly patients with gastric cancer is early diagnoses,strong perioperative management and suitable radical surgery.
