OBJECTIVETo observe the clinical efficacy of Jiakangling Capsule (JC) combined with reduction of 1311 in treatment of Graves hyperthyroidism.

METHODSTotally 387 Graves hyperthyroidism patients were randomly assigned to the treatment group (200 cases) and the control group (187 cases). Patients in the treatment group took JC combined with reduction of 131I. The 131I dosage per gram of thyroid tissue was 50-80 microCi. They additionally took JC one week after taking 1311 for one consecutive month. Patients in the control group took 131 routinely as one disposable treatment. The 131I dosage per gram of thyroid tissue was 70-120 microCi, without using JC or other anti-thyroid drugs. All patients were reexamined after 24-month treatment. Whether hyperthyroidism was cured, incurred, or permanent was observed. Efficacies of thyroglobulin antibody (TGAb) and thyroid microsome antibody (TMAb) were compared between the two groups.

RESULTSCompared with the control group, the incurred ratio increased in the treatment group [3.2% (6/187) vs. 16.0% (32/200), P < 0.01], the incurred ratio of strong positive TGAb and TMAb patients increased [3.5% (2/57) vs. 27.1% (16/59), P < 0.01], the permanent hypothyroidism ratio decreased [21.1% (12/57) vs. 3.4% (2/59), P < 0.05 ].

CONCLUSIONJC combined with reduction of 1311 was superior in treating Graves hyperthyroidism induced permanent hypothyroidism than routine 1311 treatment, especially for strong positive TGAb and TMAb patients.

Objective To compare the propagation speed and physical parameters between underwater blast wave and air blast wave. Methods The physical parameters of blast wave were measured by PCB pressure transducers (USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed. Results Underwater blast wave was characterized by high propagation speed, high peak overpressure value, great impulse, however, short duration. Compared with air blast wave, the propagation speed of underwater blast wave was 3.70-4.30 times higher than that of air blast wave, the peak overpressure value was 227.15-247.86 times higher, and the impulse was 8.48-11.80 times greater than that of air blast wave. Conclusion Underwater blast wave propagates faster than that air blast wave. Meanwhile, it also peoduces higher peak overpressure value and impulse. This result is helpful for the evaluation of injury severity and treatment of underwater blast injury.

Pointing to the contradiction features existent in teaching of clinical practice in the beginning stage of establishing affiliated hospital of university,it primarily discusses the management method in teaching of clinical practice,which gets first achievements after 3-year trial.

Objective To observe expression changes of the telomeric repeat binding factor 2 (TRF2) in mouse cortical neurons during aging and its biological significance.Methods TRF2 expression in cortical neurons of young (2 months) and old (20 months) C57BL/6J mice were tested by Western blot and real time PCR.pcDNA-TRF2 was transfected in embryonal cortical neurons.Neurons viability was determined by MTT after exposure to camptothecin for 16 h.Results TRF2 expression decreased significantly in cortical neurons in old mice than that in young mice.After exposure to camptothecin for 16 h,(75.4±2.6) ％ of pcDNA TRF2 transfected neurons were viable and the transfection rate was higher in pcDNA-TRF2 transfected neurons than in control transfected neurons [(32.6 ± 9.3) ％] (t =22.85,P ＜ 0.05).Conclusions TRF2 expression decreases significantly in aging mouse,downregulation of TRF2 may participate in neurons aging,and TRF2 overexpression may be a potential therapeutic target against neurodegeneration.

Matrix metalloproteinase (MMP)plays an important role in the degradation of extracellular matrix components,which is crucial for tumor growth,invasion and metastasis.As one with the largest relative molecular mass in MMP family,MMP-9 takes part in the generation and progression of colorectal cancer. Research shows that MMP-9 can be used for the early diagnosis of colorectal cancer.The expression levels of MMP-9 in tissue and plasma are negatively correlated with prognosis of the postoperative patients with colorectal cancer.In addition,targeted therapy drugs will be designed on the basis of MMP-9 expression increased in colorectal cancer.
