Objective To investigate the roles of a variety of cytokines including transforming growth factor beta (TGF-β),interleukin-6 (IL-6) and interleukin-2 (IL-2) in the differentiation of CD+4 Tlymphocyte cells.Methods T lymphocyte cells either in human peripheral blood or routine spleen were cultured in vitro under different stimulation conditions.Flow cytometry was used to analyze the percentages of CD+4IL-17+ T-helper 17(Th17) cells,CD+8 IL-17+ T cells,CD+4 CD+25 FOXP+3 T regulatory (Treg) cells among activated T cells.Results Differentiation of Treg cells,Th17 cells and CD+8 IL-17+ T lymphocyte cells was enhanced when murine splenic T cells were cultured with TGF-β.The levels of expression were (7.8±2.2)%,(12.6±3.1)%,(10.1±2.6)% ,respectively.Experimental control group was severally same type of T cells without cytokine treatment.The levels of expression were (4.8±0.6) %,(1.7±0.5) %,(1.0±0.4) %,respectively.There were statistically significant differences among them (q=4.09,8.80,9.61.P<0.05 or P<0.01).Under combination treatment with IL-6 and TGF-β,(17.8±5.3) % Th17 cells and (15.0±4.2)% CDCD+8 IL-17CD+ T cells were induced,whereas the levels of Treg cells whose differentiation were restrained were (4.1±1.2) %.The differences were statistically significant compared with the level of same type of T cells in TGF-β group (q=5.03,5.17,5.04,P<0.01).Moreover,combination treatment with IL-2 and TGF-β decreased percentages of Th17 and CDCD+8 IL-17CD+ T cells and increased percentages of Treg cells in T cell population.There was an opposite effect when anti-IL-2 was apphed.The percentages of Th17 and CD+8 IL-17+ T cells were increased and the percentages of Treg cells were reduced The regulation trend of T lymphocyte cells in human peripheral blood was similar with those in routine spleen.Conclusion Various cytokines are of great importance in the regulation of the balance between Th17 and Treg cell.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine,which not only affects spinal anatomy,mobility and trunk symmetry,but also leads to the changes of human locomotion through pelvic.During the past 30 years,though great progress has been made in the treatment of AIS,the pathogeny of AIS is still uncertain.Most scholars believe that many factors contribute to the pathogeny of AIS,however,some studies have shown that poor posture during walking and poor manage of balance could lead to the progress of scoliosis.Gait is a behaviour characteristic during walking,and normal gait is the result of nervous system,musculoskeletal system,proprioception and vision.Any disease of the system above may cause abnormal gait.Gait analysis can spot the key links and impact factors of abnormal gait by observing and measuring the testers' walking,reflect the abnormal gait objectively and quantitatively,and provide reference opinions for the recovery and treatment of patients.At present,gait analysis has been mostly applied in hemiplegia,cerebral palsy and knee osteoarthritis.In recent years,gait analysis has been increasingly used in AIS patients.There have been many researches about the kinematics and kinetics of gait analysis in adolsecent idiopathic scoliosis abroad and some positive results have been reported..But in China,it's still in the initial stage.We reviewed the published papers about gait analysis in AIS patients,and summarized the kinematics,kinetics and different means of intervention on gait in AIS patients.We hope it will provide references for our researches.

The apparent digestibilities of two preparations of corn as staples in men were estimated during March and April in 1979. Seven healthy adult men, who lived in this region for many years, were accustomed to eat corn as their staple diets. Each of the two preparations from the same batch of corn was used in the experiment. One preparation was "cooked corn meal" and the other was Jian-bing, the latter was considered the better way of cooking. Other ingredients of food in these two test diets were the same. During the test periods, the volunteers ate the test diets and drank boiled water ad lib, but the quantities were recorded. No other foodstuffs and drinks were allowed. The nutritive values of test diets were sufficient to meet the subjects' physiological needs. The 12 days period was divided into adaptative and testing periods of three days each for the two kinds of test diets. During the test periods, the total foodstuffs and the volunteers' faeces were analysed for the contents of water, anhydrates, total ni- trogen, crude fat, ash and fiber in the samples. From the data obtained, the apparent digestibilities of anhydrates, total nitrogen and crude fat ware calculated. Urine nitrogen was analysed and the nitrogen balance was calculated. The body weight at the beginning and the end of test periods were measured.The apparent digestibility (%) of anhydrates was 93.31?0.393 and 94.79 ? 0.578, total nitrogrn 84.60 ? 0.843 and 87.77 ? 1.080 and crude fat 86.32 ? 1.296 and 94.68 ? 0.838 in cooked corn meal diet and the corn flour Jian-bing diet respectively. The apparent digestibility in corn Jian-bing diet was higher statistically than that of cooked corn diet. Body weights fluctuated within the normal range. The nitrogen balances of all subjects were positive and the difference of nitrogen balance studies between the two test diets was not statistically significant.The results of the experiment suggest that, the differences of apparent digestibility between two diets was mainly due to the methods of preparation, Jian-bing being better than cooked corn diet in human nutrition.

Objective To observe the clinical curative effect of cinobufacini injection in the treatment of primary bronchopulmonary carcinoma.Methods 120 patients with primary bronchopulmonary carcinoma were randomly divided into the control group and treatment group,60 cases in each group.Patients of the control group were treated with the general,symptomatic and dialectical therapy.Patients of the treatment group were given general,symptomatic,dialectical treatment and cinobufacini injection.The curative effect was determined by the standard efficacy of tumor,the survival quality of the patients was judged by the Karnofsky score.The adverse reactions,median survival time and the survival rate were compared between the two groups.Results The effective rate of the control group was 40.0％,that of the treatment group was 56.7％,the difference was statistically significant (x2 =4.034,P ＜ 0.05).By the Karnofsky score,27 patients of the control group were stable,39 patients of the treatment group were stable,the difference was statistically significant(x2 =12.265,P ＜0.05).Median survival time of the control group was (168 ± 16) d,that of the treatment group was (178 ± 20)d,the difference was statistically significant(x2 =12.265,P ＜ 0.05).One year survival rates of the control group and the treatment group were 5.0％,10.0％,the difference was statistically significant.There was no statistically significant difference between two groups in adverse reactions (P ＞ 0.05).Conclusion Cinobufacini injection can improve the quality of life and prolong survival of patients with primary bronchopulmonary carcinoma.It is effective and safe in clinical application.

Objective To evaluate the relationship of diurnal variation of antidiuretic hormone (ADH) with urinary output,serum osmolality and blood pressure in spinal cord injury (SCI) patients. MethodsThe study was prospective,random and contrastive. Twenty complete SCI patients (two females and 18 males,Complete SCI group) and ten healthy controls (two females and eight males,control group) were studied. Urinary output and osmolality in the day time (8:00-20:00) and at night (20:00-8:00) were recorded. Blood samples for the measurement of serum osmolality and ADH were drawn at 14:00 and 2:00. Results There was very significant difference in regard of urinary output between day time and night time in complete SCI Group and control Group ( P 0.05). However,ADH level increased in the healthy Group at night,with a very significant difference ( P

Objective To analyze and determine the efficient T- and B-combined (T/B) antigenic epitopes in Helicobacter pylori adhesin A. Methods Recombinant HpaA (rHpaA) was expressed for immunizing rabbit to generate antiserum. T- and B-cell epitopes in HpaA molecule were predicted by using bioinformatic technique. The segments to encode T/B combined epitope peptides were amplified by PCR and the phage display systems of T/B combined epitopes were subsequently constructed. PEG/NaCl precipitation method was applied to extract the recombinant phage PⅢ (rPⅢ) that displayed T/B combined epitopes. By using either commercial IgG against whole-cell of Helicobacter pylori or rHpaA antiserum as the primary antibody, the T/B combined epitopes displayed in rP Ⅲ s were screened and identified by Western blot and ELISA. MTT was applied to determine the proliferation of rHpaA-immunized mouse splenocytes after stimulation of the different recombinant rPⅢ proteins. Results In the HpaA molecule there were five T/B combined epitopes: HpaA10, HpaA37, HpaA79, HpaA116 and HpaA143. All the T/B combined epitopes were successfully displayed on the surface of PⅢ protein of phage M13. The results of Western blot, ELISA and MTT confirmed that HpaA116 was the predominant antigenic epitope, both HpaA37 and HpaA79 were the efficient antigenic epitopes. However, HpaA10 and HpaA143 were identified as ineffective antigenic epitopes. Conclusion The phage display systems of T/B combined epitope peptides of H. pylori adhesin A have been successfully generated in this study. HpaA37 and HpaA79, especially HpaA116 are the efficient T/B combined antigenic epitopes in HpaA of H. pylori.
