Pituitary stalk interruption syndrome(PSIS) is a rare disease characterized by different degrees of anterior pituitary hormone deficiency.The typical imaging finding is a thin or absent pituitary stalk,often associated with an ectopic posterior pituitary and a hypoplastic anterior pituitary.The cause is still unkown.Dynamic contrastenhanced MRI helps to confirm the diagnosis.Replacement of multiple anterior pituitary hormones is the key of the treatment.Doctors should have a thorough understanding of the disease and give patients efficacious treatment and a better prognosis would be obtained.

Objective　To explore the prophylactic effect of T cell vaccination (TCV) on type 1 diabetes. Methods　6-week-old nondiabetic femele NOD mice were vaccinated intraperitoneally with the attenuated, activated T lymphocytes isolated from the spleen of 4-week-old nondiabetic NOD mice, 18-week-old newly diabetic NOD mice and 32-week-old long-term diabetic NOD mice. The incidence of cyclophosphamide-treated diabetes, inflammatory score of insulitis in NOD mice as well as T lymphocyte subset changes in spleen and thymus were determined after TCV. Results　TCV was able to reduce the incidence of cyclophosphamide-treated diabetes, to alleviate insulitis, to increase the percentage of CD8+ T lymphocyte subset in spleen and CD4- CD8+ simple-positive T lymphocyte in thymus, and to decrease the percentage of IL-2R+ T lymphocyte and CD4+/CD8+ rate in spleen. Conclusion　TCV may decrease host autoimmunity, which seems related to the changes of T lymphocyte subsets in spleen and thymus and prophylactic effect on diabetes.

The blood supply of metatarsuses and pha-langeals in 30 cases of fetuses and infants was ob-served by microangiographic methods. The resultsdemonstrated that diaphyses and cartilages of bothends of metatarsuses and phalangeals gradually in-creased in the fetal period and appeared nourishingartery and cartilage canal. Both ends of metatar-suses and phalangeals gradually decrea.ed in the. infant period and cartilage canals gradually disap-peared also. These implied that the appearance ofcartilage canals was related to the size of cartilageblocks. Cartilage Canals were temporary bloodsystem of fetal cartilage. Characteristics of bloodsupply of metatarsuses and phalangeals: 1. Asym-metrical distribution of blood supply on metatar-suses and phalangeal, that is the blood supply ofepiphyseal end is richer than one of non--epiphy-seal end, is adapted with the difference of growthability at both ends. 2. There is distribution ofcartilage canals at the epiphyseal end of the distalphalanx, and it is adapted with having growth a-bility at the proximal end. These show that bloodsupply of metatarsuses and phalangeals is closelyrelated to their growth and development.

Objective To investigate micrometastasis in axillary lymph nodes and its relationship with nm23 expression of the tumor tissue in breast cancer patients. Methods Paraffin blocks of 832 surgically removed lymph nodes and carcinoma tissues from 52 lymph node negative cases comfirmed by routine pathology were re examined by immunohistochemical staining using monoclonal anti EMA and anti nm23 H1 respectively. Results Micrometastasis were observed in 12 of the 52 patients (23.0%) and in 34 of the 832 lymph nodes ( 4.1% ). The positive rate of micrometastasis that in the tumor larger than 2.0cm or poorly differentiated was significantly higher than in the tumor

Objective:To design the liquid level detection system by ultrasonic method to meet the requirements of automatic enzyme immunoassay workstations and have a precise detection of liquid level. Methods:Because the existing sample needle should move down, liquid surface and the poor conductivity of liquid were invalid. So a method of ultrasonic liquid level detection system was designed. The control signal was launched by a microprocessor to control ultrasonic signal generator chip and the ultrasonic signal reflected when the liquid level in a test tube or microplate. Results: By receiving the reflection echo signal sent to the microprocessor for signal processing, the liquid level was detected. Conclusion: The ultrasonic method applied to the liquid level detection system to overcome the above shortcomings, improve pipetting accuracy and avoid cross pollution, so as to meet the requirement of the automatic enzyme immunoassay workstation test.

Objective To study and observe the effect of transnasal endoscopic surgery in the treatment of patients with fungal paranasal sinusitis.Methods A total of 82 cases of patients with fungal paranasal sinusitis were collected and divided into the control group (40 cases) and the observation group (40 cases) according to the principles of random,single blind and parallel control design,the patients in the control group received conventional surgical treatment,and the patients in the observation group received transnasal endoscopic surgical treatment,the two groups were observed and compared in terms of treatment efficiency,sinus cavity scores in the lesion range,average operation time,postoperative complication rate and patients' satisfaction degree.Results The effective rate in treatment group was 94.6％,significantly higher than that of control group (80.0％);the lesions sinus cavity score was 0 points in observation group,significantly lower than the control group (13.1 ± 1.9),the average operation time was (45.4 ± 10.9) min in the observation group,significantly shorter in the control group (76.3 ± 10.5) min;the postoperative complication rate was 3.2％ in the observation group,which was significantly lower than that of 25.6％ in the control group (P＜0.05).Conclusion The transnasal endoscopic surgery in the treatment of patients with fungal paranasal sinusitis can effectively improve the treatment efficiency,remove the mold lesions in the sinuses of patients,shorten the operation time and reduce the postoperative complication rate,and is conducive to promoting the rehabilitation of patients and improving the quality of life of patients,thus it is worth popularization and application.

Objective To evaluate prognostic value of N-terminal B-type brain natriuretic peptide (NT-proBNP) combined with galectin 3 of prognostic value in patients with chronic heart failure (CHF).Methods Determination of 92 cases of CHF patients on admission and at discharge plasma NT-proBNP and galectin-3 levels,then after the patients discharge we follow up 16 months and observe the internal recurrent heart failure hospitalization rate and mortality.Results In patients the heart function of New York Heart Association (NYHA) Ⅰ,Ⅱ,Ⅲ,Ⅳ level,NT-proBNP were (351.6 ± 467.5) pg/ml,(493.2 ± 411.7) pg/ml,(1 289.6 ± 737.8) pg/ml,(2 719.2 ± 1 044.1) pg/ml,galectin-3 (12.23 ± 6.12) ng/ml,(13.59± 5.46) ng/ml,(19.18 ± 7.44) ng/ml,(26.61 ± 8.82) ng/ml as well.NT-proBNP and galectin-3 levels were increased with the depression of cardiac function.The patients who had higher NT-proBNP or galectin3 levels discharged and occurred the more probability of re-hospitalization on account of heart failure or death.Compared to those patients with one of them increased,the patients whose discharge NT-proBNP and galectin-3 value were both increased with significantly poor outcome.Conclusions Both NT-proBNP and galectin-3 were independent predictors of poor prognosis in patients with heart failure.Galectin-3 combined with NT-proBNP can assess the prognosis of patients with CHF more effectively.

The safflower floret is a traditional Chinese medicine used to promote blood circulation and remove obstruction in the channels. The spines on its bracts are considered a handicap when manual harvest is involved. In this study, cDNA-SRAP was used to systematically investigate which genes are associated with the spines. Sixty pairs of possible primer combinations were used on two cDNA pools representing spininess and spinelessness. Six transcript-derived fragments were identified, of which two with low recombination were sequenced successfully and named as GPY-1 and GPY-2. By using the RACE method, the full-length cDNA of GPY-2 is cloned and named as CTL-spn. The full-length cDNA of CTL-spn was 1 679 bp long with a 1 524 bp ORF encoding a 508 aminoacid protein. The deduced amino acid sequence of the CTL-spn gene shared a high homology (97%) with other known ATP synthase CF1 alpha subunits. Semiquantitative RT-PCR analysis revealed that the mRNA of GPY-1 and GPY-2 accumulated in only spiny lines. Considering the important role of ATP synthase CF1 alpha subunit in plants, it may directly take part in the formation process of spininess and enhancing resistance reaction of spiny safflower. Also, our results provide the important insights for breeding spineless cultivars of safflower.

Objective　To investigate the effect of intratumor injection of 131I-3H11 for gastric cancer (GC). Methods　16 patients with GC subjected to endoscopic intratumor injection of 131I-3H11 as a treatment group; 6 GC patients with FAM chemotherapy as a control group. Histological examination of the postoperative specimens of the two group were comparated. Results　In treatment group, 75.0%(12/16) of cases were found to have morphological changes with karyopyknosis, karyorrhexis, coagulation of cytoplasm, and invasion of lymphocyte in mesochyma. Most of these changes were medial; but in control group no obvious morphological change was found. Conclusions　The results suggest that GC subjected to endoscopic intratumor injection of 131I-3H11 preoperatively has promising application in the clinic.
