Hepatitis virus NAT reagents are now widely used clinically. However, the qulity of domestic and foreign NAT reagents varies dramatically. The main reasons for these differences including the manufacture technique, test principle and assay procedure were discussed in this paper and current status of the quality control of the NAT reagents were also described. Finally, it was pointed out that strengthening public supervision and laboratory internal control are very important for the quality improvement of the domestic reagents.

BACKGROUND:Previous experiment has confirmed that the nitinol artificial esophagus is an artificial succedaneum which can be used for replacing an esophagus resected and rebuilding esophageal tube.
OBJECTIVE:To observe the tissue reaction of the neo-esophagus and the adjacent organs injury contacted with the nitinol artificial esophagus after replacement.
METHODS:Eight miniature pigs were selected and modeled by resection of a 70 mm segment of the thoracic esophagus. After modeling, the nitinol artificial esophagus was inserted into the proximal and distal end of the thoracic esophagus at an insert distance of about 10 mm. After that, the nitinol artificial esophagus with polyester connecting ring was sewed into the thoracic esophagus in a manner of ful-thickness anastomosis. After operation, the pigs were subjected to feeding regulation measures to control the shedding time of the artificial esophagus. Two model pigs were sacrificed for anatomical observation at 1, 2, 3, 4 months postoperatively, respectively. The tissue reaction during the neo-esophagus formed procedure and adjacent organs injury contacted with the nitinol artificial esophagus were observed.
RESULTS AND CONCLUSION:Al pigs survived without complications such as thoracic hemorrhage, pneumothorax, pyothorax, esophageal perforation and anastomotic leakage. The experimental animals with the nitinol artificial esophagus fixed in situ had no dysphagia for eating semisolids food (Bown’SⅡ). Autopsy findings showed that there was slight membrane-like adhesion between partial pleura and lung. No hydrothorax was found. The nitinol artificial esophagus was wrapped up by the neo-esophagus. There was slight membrane-like adhesion between the neo-esophagus and the adjacent organs such as the lung, aorta and esophageal mucosa. The esophageal mucosa covered the neo-esophageal entocoele from esophageal stumps to intermedius of neo-esophagus until completely covered. Histological findings of the neo-esophagus showed that in imbed cycle of the nitinol artificial esophagus the tissue reaction showed aseprtic inflammation reaction and foreign body reaction around the implant. These tissue reactions were most severe at 1 month after operation and thereafter relieved gradual y.

OBJECTIVETo study the efficacy and safety of Reinhartdt and sea cucumber capsule (RSC) combined with donepezil in treating Alzheimer's disease (AD), and its effect on thyroid function axis.

METHODSSixty-eight patients were randomly assigned to the RSC group, the Donepezil group and the combined treatment group, who were treated for 3 and 6 months with RSC, Donepezil and RSC combined with Donepezil, respectively. The curative effect was evaluated by scoring according to Mini-Mental State Examination (MMSE), ADAS-Cog and ADL chart, and the level of thyroid hormones, including TSH, FT3, FT4, TT3 and TT4, were measured with radioimmunoassay before treatment, 3 and 6 months after treatment respectively.

RESULTSAs compared with the baseline, MMSE score increased, ADAS-Cog score and ADL score decreased significantly in all the three groups after 3 months and 6 months of treatment (P < 0.05 and P < 0.01), but the improvement in the combined treatment group was more significant than that in the other two groups (P < 0.01). After 6 months of treatment, the levels of FT3 and FT4 in the combined treatment group were significantly changed (P < 0.01), but no significant change in all the thyroid hormones was found in the other two groups. No obvious adverse reaction occurred in all the three groups.

CONCLUSIONRSC combined with Donepezil in treating AD is effective and safe with no evident adverse reaction, better than single drug treatment, which may be through influencing the metabolism of thyroid hormones to improve the cognition function of AD patients.

Objective To improve treatment success rate and prognosis for patients with bifrontal contusions by intracranial pressure monitoring.Methods A retrospective analysis was conducted on 79 cases of bifrontal contusions admitted between October 2004 and April 2012.The patients were divided into intracranial pressure monitoring group (n =40) and group without intracranial pressure monitoring (n =39),according to the treatments.Significance of high coronary craniotomy timing,surgical strategy and intracranial pressure monitoring in the diagnosis,treatment and prognosis was analyzed.Results The intracranial pressure monitoring group showed a significantly shorter period concerning osmotic dehydration [(14.24 ± 7.93) days vs (21.61 ± 11.97)days,P＜0.01],ICU stay [(14.38 ±7.56)days vs (24.71-± 17.94)days,P＜0.01] and total hospital stay [(17.20 ±8.09)days vs (33.92 ± 21.70)days,P＜0.01] as well as a better GOS [(4.15 ± 1.22) points vs (3.69 ± 1.56) points,P ＜ 0.05],as compared with group without intracranial pressure monitoring.Conclusions Craniotomy,especially decompressive craniectomy,is one of the most important treatment means to control cranial pressure and ensure cerebral perfusion pressure in patients with bifrontal contusions (in particular the moderate and severe ones).Besides,intracranial pressure monitoring is conducive to selection of surgery timing and is instructive to combined treatment,such as osmotherapy,intracranial pressure controlling and assurance of cerebral perfusion pressure.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f.,TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.However,there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN).This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP,in order to investigate the effects of triptolide on the expression of OCP in rats with DN.Sixty SD rats were randomly divided into five groups:control group,high-dose triptolide (Th) group,low-dose triptolide (T1) group,DN model group,and positive control (benazepril) group.The DN model was established using streptozotocin.Urinary protein excretion,fasting blood glucose (FBG),superoxide dismutase (SOD) in renal homogenate,malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry,and the expression of OCP by oxyblotimmune blotting were detected.In the DN model group,rat urinary protein excretion and renal MDA were significantly increased,while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney.After triptolide treatment,24-h urinary protein excretion (61.96±19.00 vs.18.32±4.78 mg/day,P＜0.001),renal MDA (8.09±0.79 vs.5.45±0.68 nmol/L,P＜0.001),and nitrotyrosine expression were decreased.Furthermore,renal OCP significantly decreased,while renal SOD (82.50±19.10 vs.124.00±20.52 U/L,P＜0.001) was elevated.This study revealed that triptolide can down-regulate the expression of OCP in the renal cortex of DN rats.

Objective To compare the sensitivity, specificity and consistency of five kits for quantitative detection of hepatitis B virus (HBV) DNA. Methods Four domestic fluorescence kits, A, B, C, and D, and Roche Cobas Ampliprep/Cobas TaqMan HBV test for quantitation of HBV DNA in serum, were applied to detect the National Standards, an additional plasma for sensitivity (7 times dilution), 15 plasma samples from healthy blood donor and 45 plasma samples from chronic hepatitis B patients. Results All five kits showed the correct results for the 9 positive specimens and 8 negative specimens from the National Standards. The quantitative results of specimens for sensitivity met requirements of the National Standards. The lowest concentration of HBV DNA by these three kits was 15.6 IU/mL. The lowest detection level of HBV DNA for domestic kit B was ≤500 IU/mL. There was linear correlation between the results by Roche kit and domestic kit C (r> 0.98). Kit D showed 2 false-negatives results in the 15 healthy blood donor samples. The coincidence rates between 4 domestic kits and the Roche kit ranged from 50% to 96% (A: 61%, B: 50%, C: 96%, D: 83 %). The consistency rate of kit C with the Roche kit was significantly higher than those of kit D, A and B (X2=5.62, P<0.05, X2=28. 93, P<0.01, X2=44.31,P<0.01, respectively). The consistency rates among these 5 kits were highest when testing samples with HBV DNA levels between 1×104-1×107 IU/mL. Conclusions The qualities of domestic kits vary remarkably and kit C has the greatest consistency rate with the Roche kit. Therefore, the qualities of domestic kits need to be further improved.

Background The incidence of posterior capsular opacification (PCO) is increasing with the growing of cataract surgery rate.Recent researches provend that disintegrin has inhibitory effect on PCO,and echistatin is one of the disintegrin prime families.Objective This study was to investigate the effects of disintegrin and echistatin on proliferation,adhestion and migration in human lens epithelial cells (LECs) line (SRA01/04).Methods Human LECs line at logarithmic growth phase was used in the study.Cells were cocultured with medium and different concentrations of echistatin (0,2.5,5.0,7.5,10.0,15.0,20.0 mg/L) for different time.The proliferative inhibitory rates of LECs were detected by MTT method 24,48 and 72 hours after cultured.Anti-adhesion effect of echistatin were analyzed by the same assay in 90 minutes.Cell scratching test was performed to evaluate the migration ability of LECs.The width of the scratch was recorded in the culture plate covered with cells under an inverted microscope.After being cultured for 24 hours and 48 hours with echistatin,cell migration distances was examined.Results Compared with the 0 mg/L echistatin group,cells proliferation was obviously inhibited.After cultured with 2.5,5.0,7.5,10.0,15.0,20.0 mg/L echistatin,the proliferation inhibitory rate was 2.6％,15.4％,21.2％,34.7％,46.1％,58.2％ at 24 hours;6.6％,21.9％,38.2％,50.0％,60.7％,76.9％ at 48 hours and 9.8％,29.0％,46.6％,63.4％,69.1％,92.4％ at 72 hours,respectively.The absorbance value (A) in the 5.0,7.5,10.0,15.0,20.0 mg/L groups were significantly lower than that in the 0 mg/L group (P＜ 0.05).With the prolongation of acting time of Ecs,the A value of the cells was gradually reduced,with statistically significant difference (P＜0.05).The adhesion inhibitory rate was 2.6％,15.0％,26.1％,35.3％,45.2％ and 54.5％ in the 2.5,5.0,7.5,10.0,15.0,20.0 mg/L group,respectively.Compared with the result in the 0 mg/L group,the A value in the 5.0,7.5,10.0,15.0,20.0 mg/L group was statistically significant (P＜0.05).After cultured for 24 hours and 48 hours,cell migration distance shortened in the 5.0,7.5,10.0,15.0,20.0 mg/L group,showing a statistically significant difference among them (P＜0.05).Cell migration distance was gradually shortened with the lapse of action time of Ecs with the significant difference (P ＜ 0.05).Conclusions echistatin has inhibitory effects on proliferation,adhestion and migration for human LECs in vitro in time-and dose-dependent manner.It is inferred that echistatin may play a role in the prevention and treatment of PCO.
