Objective To explore the more secure and available methods in replacing traeheostomy tube.Methods Sixty patients with incision of trachea were divided into group A(29 eases)and group B (31 cases)randomly.The new method was used in group A with putting a catheter into the old tracheostomy tube before taking it out,and placing the new tracheostomy tube under the guide of catheter.While the traditional method was used in group B.The heart rate,SpO2,manipulation time,perioperative haemorrhage, and the condition of entering the false passage were recorded.Results The heart rate,SpO2 were no significant difference before and after manipulation in group A,but the heart rate increased and SpO2 decreased in group B(P<0.01 or<0.05).The manipulation time was(50.5±4.2) s in group A,and (84.9±5.3) s in group B(P<0.05).The perioperative haemorrhage >3 ml and the condition of entering the false passage in group A(2 Cases,o cage)were less than those in group B(15 cases.5 cases)(P<0.01 or<0.05).Conclusion The new method in replacing tracheostomy tube which use an input catheter is more security and more availability.

The conventional therapy for arteriosclerosis obliterans (ASO) is Western medicine. However, it has some adverse effects and does not respond to some patients, and it is also very expensive.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.

Objective To investigate the brain glucose metabolism with 18 F?FDG microPET/CT in mouse models of intracerebral hemorrhage (ICH). Methods A total of 12 healthy adult male mice were randomly divided into sham operation group (group A, n=6) and ICH model group (group B, n=6) by simple random sampling method. The animal models were established by injecting collagenase Ⅳ into the caudate nucleus of mice. Thereafter (5.5±0.3) MBq of 18F?FDG was injected into caudal vein at 6 h, 24 h, 48 h and 3 d, 5 d, 8 d, 14 d, respectively, following anesthesia. 18 F?FDG microPET/CT scans were ac?quired 30 min after the trace injection. SUV in the perihematomal brain tissue of ICH was measured and an?alyzed. Two?sample t test was used to compare SUV between groups. Results ( 1) Some mice had mild neurologic deficit after the sham operation in group A, while all mice had a marked neurologic deficit in group B, especially at 24 h after 18 F?FDG injection. ( 2) After 6 h, FDG uptake in perihematomal brain tis?sue decreased(SUV=0.80±0.04), which significantly lower than that in the opposite side(SUV=1.10± 0?04;t=2.69, P<0.05) and decreased to the minimum at 24 h(SUV=0.50±0.05). 18F?FDG uptake in perihematomal brain tissue began to increase at 3 d(SUV=1.20±0.05) and kept increasing during the 14 d observation. Compared with the group A, glucose metabolism in group B was significantly lower at each time point(t=37.67-86.60, all P<0.05). Conclusions 18 F?FDG microPET/CT may dynamically reflect the changes of brain glucose metabolism in ICH mouse models. The FDG uptake in the center of ICH may disap?pear and the volume of hematoma with decreased uptake may shrink during the observation period.

In this paper, three spoilage organisms were separated from five transmutative soy milks, and all the three spoilage bacteria could survive condition of both 1?105Pa,30min and 300mg/kg Nisin. Morpha character, physiological and biochemical characteristics, and a phylogenetic analysis based on 16S rDNA gene sequences reveal that these three strains are Bacillus licheniformis, Bacillus pumilus and Brevibacillus borstelensis respectively. GenBank accessions for these three strains are EF439666-EF439668。

·Age-related macular degeneration (AMD) and retinitis pigmentosa (RP) are common outer retinal degenerative problems, which are also the predominant causes of most blinding retinal diseases. Retinal prosthesis is a promising solution for such photoreceptor degeneration diseases.Most of current concepts for a retinal prosthesis are based on neuronal electrical stimulation. In the past twenty years, retinal prosthesis has been developed in two different directions: epiretinal prosthesis and subretinal prosthesis. Each prosthesis technique has its advantages and disadvantages. For epiretinal prosthesis, it is easier to be implanted and has the advantage of keeping most of the electronics in the vitreous cavity, off the retinal surface, which greatly helps in dissipating the heat generated by the implant device. In this paper, a brief overview of retinal prostheses concepts is introduced. After that, several important aspects of epiretinal electrical stimulation will be discussed. Moreover, some practical epiretinal prosthesis devices developed by researchers in United States, Germany and Japan in the past have been reviewed. We hope that the devices will be used widely in the near future.

OBJECTIVE To established a viable and convenient method for human nasoseptal chondrocyte culture in vitro and study the biological characters of the chondrocyte. METHODS The chondrocytes were obtained by incomplete enzyme digestion of cartilage and were seeded with small piece of cartilage in 25 ml culture flasks coated with polylysine previously. This study determines the biologic synthesis of the chondrocytes by toluidine blue and type Ⅱcollagen immunohistochemistry reaction. The proteoglycan synthesis efficiencies of human nasoseptal chondrocytes cultured in vitro were measured by using 35S-Na2SO4 incorporation. The modified method and the conventional method in proteoglycan synthesis were also compared. RESULTS The results suggested that human nasoseptal chondrocytes cultured by modified method still show the normal structure and morphology, and maintain the function of metabolism and self duplication. With the modified method, we can get a higher cell survival rate and more cells. CONCLUSION The modified method is a viable and convenient method.
