Objective To study the anticoagulation effect of low molecular weight heparin ( LMWH) on hemodiafiltration by different forms of administration. Methods Twenty-four uremic patients undertook hemodiafiltration were divided into ia and iv group randomly, acecepted single injection of LMWH. LMWH was administered to 12 patients by arterial injection ( predialyzer), while in the other 12 patients by venous injection (postdialyser). The APTT were measured before treatment and at 1 h,2 h,3 h time points after treatment in all patients. The dialysis fluid and blood levels of LMWH were measured at 2 minutes,5 minutes,1 h,2 h,3 h time points after the treatment started. Results The LMWH levels during hemodiafiltration were significantly higher in iv group than ia group (0.457 ± 0.073 ) U/ml vs. (0. 217 ± 0. 053 ) U/ml, t = 9. 702, P = 0. 001 ). However there were no significant APTT, dialyzer residual substance differences between two groups (P ＞ 0. 05 respectively )Conclusions Different ways of drug administration resulted in significantly different blood levels of LMWH, but did not affect the anticoagulant effect during hemodiafiltration, which would be related to LMWH absorption on dialysis membrant.

Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) was a common complica-tion of small cell lung cancer (SCLC). Recent studies have suggested that the origin of this disease is related to seceration of tumor cells and application of medecine. The inappropriate antidiuretic hormone secretion can lead to disturbance of metabolism of water and sodium, resulting in hyponatremia. Because the symp-toms are atypical, the diagnosis is difficult. Many cases are misdiagnosed or misseddiagnosed. The primary tumor must be treated and the restriction of water intake is the main and effective method to deal with SIADH. Prognosis of SCLC patients with SIADH is poor in most reports.

Objective To explore the clinical characteristics of thyroid disease in patients with primary Sj(o)gren's syndrome (pSS).Methods A total of 81 pSS patients were retrospectively investigated for thyroid dysfunction and the presence of anti-thyroid peroxidase antibody (TPOAb),antithyroglobulin antibody (TGAb).Sex,age,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),white blood cell count,and serum immunoglobulins were also analyzed.Results Thirty-one patients were identified as having thyroid dysfunction,including 3 with hyperthyroidism,18 with hypothyroidism,and 10 with subclinical hypothyroidism.There were no significant differences in the incidences of some clinical manifestations between patients with or without thyroid dysfunction,such as dry mouth,dry eyes,joint pain,Raynaud's phenomenon,palpable purpura,peripheral neuropathy,interstitial lung disease,liver involvement,and renal tubular acidosis.Differences were not statistically significant for ESR and CRP between two groups.Also,the titers of anti-nuclear antibody,anti-SSA antibody,antiSSB antibodies,and rheumatoid factor between two groups showed no significant differences.However,white blood cell count [(5.65 ± 0.49 vs 7.22 ± 0.48) × 109/L,P＜0.05] and hematoglobin [(110.50 ± 3.64 vs 122.80 ± 3.02) g/L,P＜0.05],as well as the titers of TGAb [(587.30 ± 204.30 vs 58.76 ± 13.78) U/ml,P＜0.05] and TPOAb [(213.70 ± 39.64 vs 29.57 ± 8.49) IU/ml,P ＜ 0.05] were significantly different between the two groups.Conclusions Thyroid diseases are frequently associated with pSS.Therefore,extended screening for existing thyroid diseases during the routine assessment of pSS patients is recommended.

Objective Ryanodine receptor (RyR) is one of the Ca2+ release channels on the intracellular Ca2+ stores. RyR induced-Ca2+ release is activated by the voltage-dependent Ca2+ entry, that is, calcium-induced calcium release (CICR). Intracellular free Ca2+ concentration (ECa2+]i) plays a key role on cochlear function. Our study is to investigate the differential expression of RyR in the developing rat cochlea, and to analyze the relationship between the expression of RyR and auditory functional development. Methods Immature SD rats, which were 1 day (P1), 5 days (P5), 10 days (P10), 14 days (P14), 28 days (P28) after parturition, and adutl rats(5 rats for each age) were included in the study. Frozen cochlea sectioning and immunofluorescence were applied to observe the differential expression of RyR. Results The RyR expression in the Corti's organ increased during the cochlear development. It's not significant that the stain was observed on the hair cells and supporting cells in the Corti's organ of P1 and P5 rats. The appearance of the Corti's organ of P10 rats trended to maturity. In P14 rats the RyR expression on hair cells located in the synaptic area against the afferent or efferent nerve, and the strain on supporting cells was extensive. There was little different between the strain on cochlea of P14 and P28 rats. In postmature rat spiral ganglion neurons (SGN), the RyR expression verged gradually from extensive whole cell soma to the synaptic area near to the plasma membrane. Conclusion The RyR expression peaked the 14th day after parturition, which was close to that in the mature cochlea. The time course of the RyR expression during the cochlear development was coincident with that of the auditory functional development. The RyR expression on both hair cells and SGNs located in the synaptic area near to the plasmolemma, implying that RyR induced-CICR was related to the auditory functions such as neurotransmission. Extensive RyR expression in the soma of SGNs at the early stage possibly involved in apoptosis of SGNs during neuron development.

Objective To explore the clinical features,diagnosis and treatment of solid-pseudopapillary tumor(SPT)of pancreas.Methods The clinical data of 19 patients with SPT treated in 8 years were studied retrospectively,included 3 males and 16 females.Results The type of operation was decided by the size and location of tumor.Pancreatic leakage was a familiar complication,there were 9 cases.Patients were followed up from 3 to 70 months,and no recurrence or metastsis was found.Conclusion Pancreas SPT is a rare type neoplasm of pancreas.Pancreas SPT is affecting primarily young women,complete resection results in excellent prognosis.

Objective To investigate the teaching effects of Sandwich teaching mode applied in clinical oncology teaching.Methods Totally 72 clinical medicine undergraduates were divided into two groups randomly:Sandwich teaching group and traditional teaching group.Sandwich teaching mode was introduced to Sandwich teaching group while traditional teaching mode was carried out in traditional teaching group.Questionnaires and test paper were analyzed between the two groups and two teaching modes were evaluated.Examination results were statistically analyzed by t test.Results According to the questionnaires,more than 80 percent of the students thought that the initiative and enthusiasm were fully mobilized by the Sandwich teaching mode.Studying efficiency was improved significantly and skills of independent thinking,comprehensive analysis and problem-solving were trained,meanwhile,Sandwich teaching mode can improve the ability of expression and communication.Test score of students in Sandwich teaching group was higher than those in traditional teaching group (P＜0.05).Conclusions Sandwich teaching mode has obvious advantages in improving teaching quality of clinical oncology and it may help to cultivate high quality oncology specialists.
