?-GT activity and its substrate GSH content in tissue homogenate, epithe-lium and stroma of normal and benign hyperplastic human prostates were measured tostudy their relationship with pathogenesis of benign prostatic hyperplasia (BPH). Theresults were: a) ?-GT activity in BPH tissues were very much increased; but GSHcontent was much decreased; b) The ?-GT activity in epithelium of both normal andBPH were much higher than that in relative stroma. However epithelium GSH contentwere lower than that of stroma. Thase results suggested that increand ?-GT activity anddecreased GSH content play an important role in pathogenesis of BPH.

Objective To investigate the application of get-well treatments in the suffers after thorax opera- tion over 70 years old. Methods 68 suffers after thorax operation over 70 years old were divided to two groups. Comparison group( n = 32 ) is actualized general nurse. Experiment group( n = 36) is actualized lung function exercise before operation, and get-well treatments after operation, such as psychologic get-well, deep breath, abdominal breath, effective cough and sputuming, applying apparatus training breath; exercise limbs and body, atomization in- breath, and so on. Results The suffers in experiment group who have lung atrophy,lung infection, liquid in the tho- rax,the time in the hospital and the time holding thorax pipe are less than the suffers in comparison group. Conclu- sion Lung function exercise before operation and effective get-well treatments after operation have significant ef- fects on old suffers.

OBJECTIVE:To discuss the general rule on checking and acceptance of drug warehousing of prepared slices of Chinese crude drugs.METHODS:The warehousing acceptance data of prepared slices of Chinese crude drugs during 2003-2007 in our hospital were sorted and the reasons for drug acceptance rejection were analyzed.RESULTS:Of the 5 228 batches of prepared slices of Chinese crude drugs checked before acceptance over 5 years,138(2.61%) were unacceptable.Most of the rejected batches were prepared processing slices of Chinese crude drugs.There were more than 30 factors resulted in the rejection.CONCLUSION:The key to ensure the quality of prepared slices of Chinese crude drugs is to improve their processing level.

Prostatic stromal fibroblasts were obtained from human fetal prostate and the effect of androgen (DHT) , estrogen (E2) , and human prostatic growth factor (hPGF) on the proliferation of the cultured fibroblasts was studied. The results showed that: 1) DHT and hPGF had significant stimulatory effect on proliferation of the cells; DHT had a delayed stimulatory effect, while hPGF had an immediate one. 2) E2 had no effect on proliferation of the cultured fibroblasts. 3) Used jointly, E2 and DHT had no stimulating effect on the proliferation of the fibroblasts. The results suggest that the effect of DHT on the proliferation of human prostatic stromal fibroblasts may be indirect. It possibly regulates the growth of prostate by stimulating autocrine or paracrine function of the prostatic cells.

Acupuncture was frequently used for alternative treatments in Parkinson's disease because of its safety,but there was an argument whether acupuncture improves motor symptoms or not.Besides,few electrophysiological studies were designed for acupuncture combined with Parkinson's disease Using the technique of paired transcranial pulse magnetic stimulation,we measured the excitability of corticocortical inhibitory circuits to investigate effects of scalp acupuncture from 9 patients with Parkinson's disease.Although patients didn't take any short-term benefit in motor symptoms through the treatment of scalp acupuncture,there was no any adverse event,and some electrophysical effects developed in patients.The enhanced corticocortical inhibition on motor cortex possibly developed at longer interstimulus intervals,and there was a relatively increase in later part of motor-related cortical potentials on the central part and right-side near vertex around over sensory cortex,but was not significant in early potentials.So a further long-term study is essential to ascertain the physical mechanism and clinical effects in scalp acupuncture.

To explore the relationship between thyroid autoantibodies and thyroid function in school children aged 8-10 years,adults,pregnant women,and lactating women in China,in order to provide reference for the prevention and monitoring of thyroid disease.Healthy 8-10 years old school children (693 cases),adults (698 cases),pregnant women(325 cases),and lactating women(332 cases) from six iodine sufficient areas were enrolled.Serum TSH,FT4,and FT3 were determined by chemiluminescent immunoassay,while antithyroid antibody by radioimmunoassay.The positive rate of thyroid autoantibodies in females was significantly higher than that in the male (5.6％ vs 2.0％ in school children,and 22.8％ vs 3.2％ in adults) ; while positive rate of autoantibodies in pregnant and lactating women (8.9％,8.7％) were significantly lower than that in the other healthy adult women (22.8％).The incidence of abnormal thyroid function in antibody-positive people was higher than that in negative ones in all groups,and abnormal thyroid function showed mainly as subclinical hypothyroidism.In addition,lactating women with negative autoantibodies presented a higher incidence of abnormal thyroid function,mainly as low FT4.The abnormal thyroid function is related with the positive thyroid autoantibodies,indicating that it is essential to follow-up these people with positive antibodies in order to facilitate prevention,early diagnosis,and treatment of thyroid disease.Reference data for thyroid hormones in lactating women should be establisbed as soon as possible.

This study was aimed to investigate short-term modulation mechanism of scalp acupuncture according to the experimentation of cortical excitability and motor-related cortical potentials in ten normal volunteers.Through scalp needle stimulation in specific theoretical areas related to underlying cerebral surfaces,scalp acupuncture can be used as an effective therapy by changes in relative cerebral function,which is the basic principle.According to the available neurophysiological data in our study,the modulation of scalp acupuncture displayed in late part of motor-related cortical potential noticed mainly in the motor and sensory cortexes,contralateral to the needle stimulate site.Also,acupuncture can develop inhibition at longer interstimulus intervals,in paired pulse magnetic stimulation,from the somatosensory input of contralateral sensory cortex via scalp needle stimulation.In our study,it might be difficult to produce more acupuncture inhibition.The maintaining of scalp needles subcutaneously without other management after achieving needling sensations cannot achieve the requested strength of the acupuncture stimulation.

Objective To assess the clinical effects and adverse reactions of different regimens of chemotherapies for elderly patients with advanced gastric cancer. Methods 95 elderly patients with advanced gastric cancer were randomly divided into 3 groups. The regimens of OLF,OX and HCF were used to treat 38 patients,25 patients and 32 patients respectively. The short-term curative effects and side effects on tumor were gradeded according to the criteria formulated by WHO. The curative effects and adverse reactions were assessed and the time of disease progression was calculated at least 2 cycles after chemotherapy. Results The efficacy rate was 55.26%, 60. 00% and 53. 13% respectively,and statistical analysis showed no significant difference(P ＞ 0.05). The time of disease progress was 23,30 and 24 weeks respectively, there were significant differences (P ＜ 0.05). The major side effect were neutropenia, gastrointestinal reactions, and were able to be tolerated without a chemotherapy-related death. Conclusion Three regimens of chemotherapies had better curative effects and mild side effects for elderly patients with advanced gastric cancer,and could improve the quality of life of the patients,and are worth of clinical promotion.
