This is to study the clinical features of thyrotoxic periodic paralysis (TPP) caused by Graves′ disease. Fifty-nine patients, accounting for 25.4% of 232 patients with Graves′ disease, were found to be suffering from TPP. Among them, 58 were male and one was female. 54 patients were young men (age 19～45) (91.5%). Hypokalemia was found in 53 cases (89.8%) during episodes of paralysis. The results indicate that the rate of TPP caused by Graves′ disease is 25.4%, and it occurs mainly in young men(98.3%). Hypokalemic periodic paralysis was the most common type of TPP.

Objective To compare the value of time-resolved fluorescence immunoassay (TRFIA) and ELISA for the detection of HBV serological markers .Methods To detect the HBV serological markers in 359 samples with low concentrations of HBsAg by TRFIA and ELISA respectively ,and to compare the results of the two methods .Results The levels of HBV serological markers detected by TRFIA were higher than those detected by ELISA .The positive rates of HBsAg ,HBeAg and HBcAb detected by TR-FIA and ELISA were significantly different(P<0 .05) ,while those of HBsAb and HBeAb were not(P>0 .05) .Conclusion Com-pared with ELISA ,TRFIA has higher sensitivity in the detection of low HBsAg concentration samples ,and it is valuable to be ap-plicated in clinical .

A strain,Actinobacillus succinogenes CGMCC 1593,producing succinic acid was isolated from bovin rumen,which could pro- duces succinic acid by anaerobic fermentation.A series of morphological and biochemical characteristics and sequence analysis of 16S rDNA reveal that it belongs to Actinobacillus succinogenes.When cultured anaerobically in medium containing 60 g/L glucose as carbon source,the strain produces 25.8 g/L of succnic acid.

An inner-bioreactor rapid filtration sampling probe was designed to resolve the problems of continuous sampling the fermentation broth in on-line measurement the fermentation process. The probe consists of a support, a plug valve, an O-ring, a filter membrane and a pipe cover. It can be inserted directly into the bio-reactor withstanding high-temperature sterilization before fermentation, or preventing the bacteria's invasion during sampling. Fermentation broth in tank is cross-flow filtrated by a cylindrical ceramic membrane which is used as filtration membrane, and then the sterile permeated liquid is transported to the analyzer by a peristaltic pump. The sampling experiments using this device was described for sampling glucose solution indicating it is suitable for fermentation online sampling. The sampling rate is up to 3. 0 mL/ min, glucose permeability maintains 100% , and the delay time caused by the probe is about 2 min.

Objective To analyze the CT features of lung alveolar echinococcosis and assess the value of CT scanning for the diagnosis of this disease. Methods The CT features of lung alveolar echinococcosis in 26 patients diagnosed pathologically or clinically were reviewed retrospectively and correlated with histopathology.Results Lung alveolar echinococcosis appeared as multiple lesions bilaterally in 18 patients, as multiple lesions unilaterally in 6 patients, and as single lesion bilaterally in 2 patients. Seventeen cases presented as masses and nodules,8 patients presented as nodules,1 patient presented as a mass. Lobulation and spiculation were showed in most lesions, irregular cavity or bubble-like opacity in 13 patients,calcification in 18 patients,a patchy area or fibrotic cord around lesion in 14 patients. Pleural thickening adjacent to the lesion in 20 patients. Conclusion Lung alveolar echinococcosis has characteristic features on CT, and CT can provide important information for the diagnosis of lung alveolar echinococcosis.

Objective To investigate the value of conventional ultrasound combined with contrast‐enhanced ultrasound in qualitative diagnosis of benign and malignant cervical lymph nodes (LNs) .Methods Totally 129 enlarged LNs in 112 cases were performed the 2‐dimensional ,color Doppler ultrasound ,and grey‐scale contrast‐enhanced ultrasound(CEUS)examinations .LNs were divided into the benign group and malignant group according to pathologic results .The aspect ratio ,eccentric medulla or medulla de‐fect ,echo type ,blood supply distribution ,contrast‐enhancement pattern and distribution equilibriuym of contrast agent were com‐pared between the two groups .Results The most of aspect ratio in the benign LNs group were ≥ 2 ,the cortex and medulla were uniform with symmetric increase and without microcalcification ,the blood supple was mainly the non‐blood flow type or hilar type , in contrast‐enhanced ultrasound ,the majority were the early hilar and medullar enhancement ,showing the centrifugally full filling ;the most of aspect ratio in the malignant LNs group were <2 ,medulla was eccentric or loss ,partial of LNs showed the increased parenchymal echo accompanied with cystic lesion and microcalcification ,the blood supply was mainly the peripheral and mixed types ,and the non‐hilar and medulla started enhancement pattern .The ultrasonographic parameters mentioned above were statisti‐cally different between the two groups ,in which the non‐hilar and medulla started enhancement patterns had the highest sensitivity and accuracy for diagnosing malignant LNs ,the positive predictive values of these parameters were higher ,whereas the negative predictive values were lower .Conclusion The conventional ultrasound combined with contrast‐enhanced ultrasonography has a higher practical value in qualitative diagnosis of cervical LNs ;the comprehensive judgment of multiple indicators can increase the differentiating ability for benign from malignant LNs .

Objective To evaluate regional right ventricular longitudinal function in fetus using velocity vector imaging(VVI),and establish nomogram of right ventricle,Methods One hundreed and seventy healthy fetuses were divided into 5 groups according to the gestational age.Dynamic digital views of four chamber view were collected and analyzed offline.Velocity,strain and strain rate were calculated in systolic and diastolic period,respectively.Results Normal systolic and diastolic values for velocity,strain and strain rate were established.Tissue velocity gradually decreased from the base segment to the apical segment(P＜0.05),whereas strain and strain rate were stable(P＞0.05).Tissue velocity was gestationalage dependent(P＜0.05),whereas strain and strain rate were stable throughout gestation (P＞0.05).Conclusions Fetal myocardial velocity,strain and strain rate measurements are easy to obtain and reproducible.Increase in tissue velocity throughout gestation probably reflects the growth of the fetal heart,whereas intrinsic myocardial properties as measured by strain and strain rate do not change.
