OBJECTIVE To investigate the expression and their clinical significance of uPA (urokinase type plasminogen activator) and integrin?4 in papillary thyroid cancer. METHODS The levels of uPA and integrin?4 were determined by Immunohistochemistry technique (S-P method) in 36 specimens from patients with papillary thyroid cancer, 30 specimens from benign thyroid tumor and normal thyroid tissues adjacent to benign thyroid tumor. RESULTS The levels of uPA and integrin?4 in benign thyroid tumor were significantly higher than that in normal tissue adjacent to benign thyroid tumor (P

To resolve the agastric syndrome after total gastrectomy, researchers have performed varoius alimentary tract reconstruction procedures for patients. Meanwhile, because of controversial standpoints fol-lowing the total gastrectomy, more than eighty methods were published in the world. The highlight is focused on the discussion of whether a reservoir with the duodenal passage of foodstuff significantly beneficial to the patient's clinical and nutritional status after total gastrectomy. In this article, we reviewed and evaluated the progress of digestive tract reconstruction procedures after total gastrectomy in order to obtain a optimal opera-tion approach.

The methods of 1H Nuclear Magnetic Resonance (NMR) and mass spectroscopy were used in detecting the metabolites of brodimoprim (BDP) in rat plasma. The endogenic compounds in the plasma were removed with solid phase extraction (SPE) column firstly, then the mixture of metabolites was identified with 1H NMR and mass spectroscopy (MS). Two metabolites of BDP in the plasma at 20h were detected, they were demethyl-brodimorpim glucuronide and brodimoprim sulfurate. The study proved that the method of SPE coupled with NMR and MS can be applied to the analysis of metbolites in plasma quickly and conveniently.

Objective To observe effects of artemisia argyi moxibustion therapy Yizhichan (one finger Zen) on sleep, attention ability and TCM constitution of athletes suffering chronic fatigue syndrome (CFS);To study the safety intervention model of CFS athletes.Methods Fifty-three cases of CFS athletes were divided into control group of 26 cases and trial group of 27 cases through random single-blind method. The control group was treated with passive gimmick massage relaxation process on waist and limbs. Based on this basic treatment, the trial group was treated with application of artemisia argyi moxibustion therapy Yizhichan. After 3 treatment course, the changes of SCL-90 scale, letter cancellation test, Pittsburgh sleep quality index scale (PSQI), and TCM constitution were observed.Results After treatment, SCL-90 scale, other two factor scores, time of letter cancellation test, PSQI sleep quality, falling sleep time, sleep time, sleep disorder, daytime dysfunction project factor scores of PSQI, and the peaceful constitution had statistical significance between the two groups (P<0.05).Conclusion Specific artemisia argyi moxibustion therapy Yizhichan and fumigation can safely and effectively treat athletes with CFS on physical health, attention level and sleep quality, which is beneficial for the exploration of traditional moxibustion methods.

Objective To study the effects of Yizhichan moxibustion on chronic fatigue syndrome (CFS) athletes.Methods 143 patients of CFS were blind randomly devided into3 groups, which were moxibustion of Yizhichan (56 cases) group, general moxibustion group (42 cases), and normal group (45 cases).The normal group was treated by passive massage for relaxation, the moxibustion of Yizhichan group was treated by specific acupoints application of moxibustion of Yizhichan in addition to passive massage;and the general moxibustion groupwas treated by general moxibustion in addition to passive massage.All sample were treated once a day for 6 days in a week.3 weeks was a period of treatment, and the total time of treatment was 15 weeks.Results After treatment, the sleep quality (1.73 ± 0.73, 1.54 ± 0.85 vs.0.83 ± 0.52, F=14.130), time for sleep (1.57 ± 0.60, 1.35 ± 0.60 vs.1.03 ± 0.54, F=5.386), sleep time (1.78 ± 0.71, 1.77 ± 0.61 vs.0.67 ± 0.65, F=19.811), daytime dysfunction (0.78 ± 0.83, 1.64 ± 0.83 vs.1.03 ± 0.83, F=4.798) in the control group, moxibustion of Yizhichan group and a general moxibustion group were statistically significant(P＜0.05).The total effective rate of the moxibustion of Yizhichan group was better than the control group and the general moxibustion group (83.8％, 42.2％ vs.63.6％;x2=13.973, P=0.001).Conclusion Specific acupoints moxibustion of Yizhichan is a beneficial exploration of moxibustion methods of traditional Chinese medicine, and can improve CFS athletes level of physical health, attention and sleep quality.

BACKGROUNDTo evaluate therapeutic outcome of limited stage small cell lung cancer treated with chemotherapy alone or combined with radiation therapy with different doses.

METHODSA retrospective analysis was performed in 128 limited-stage small cell lung cancer patients who were treated with three different ways of treatment, from February 1988 to March 1998 in Heilongjiang Cancer Hospital. All patients were pathologically proved. Forty-two patients received chemotherapy alone (C), 48 patients were treated by interdigitating chemoradiotherapy (IDG) and other 38 patients received concurrent chemoradiotherapy (CON). For thoracic radiation, 20 patients received a dose of ≤45 Gy, 23 ≥60 Gy, and 43 > 45 Gy but < 60 Gy .

RESULTSThe 3-year survival rates were 23.7%, 20.8% and 4.8% in the CON, the IDG and the C groups respectively. There was a significant difference between the CON and the C groups ( P < 0.05), as well as between the IDG and the C groups ( P < 0.05). There was no remarkable difference between the CON and the IDG groups ( P > 0.05). Loco-regional recurrence rate was significantly higher in ≤45 Gy group (55.0%) than that in ≥60 Gy group (8.7%)( P < 0.01).

CONCLUSIONSThe chemotherapy combined radiotherapy may improve the survival of patients with limited-stage small cell lung cancer. Dose of thoracic radiation might be related to the loco-regional recurrence.

Doppel protein (abbreviation Dpl) is a newly recognized Glycosyl phosphatidyl inositol (GPI) anchored and highly glycosylated protein, which is similar to prion protein (PrP) in the chemical structure. The encoding gene of Dpl named PRND locates at the downstream of the prion protein gene (PRNP). These two proteins are different in physiological functions. The expression of Dpl focuses on testis tissue at the adult, and takes an important role in maintaining sperm integrality, normal fertility, and motion ability. We reviewed the biological characters, physiological functions of Dpl and its effects on male reproduction in order to provide theory guidance for the study on physiological function and male reproduction controlling.
