Chinese Journal of Laboratory Medicine 2015;38(12):884-887
Thyroid peroxidase antibody (TPOAb) play an important role in the diagnosis of autoimmune thyroid disease.Chemiluminescence immunoassay (CLIA) is a new method been strongly recommended in recent years.The definition of positive value of TPOAb is inconsistent.The definition of TPOAb positive value is important for exploring the development of autoimmune thyroid disease.TPOAb is significantly increased in Hashimoto's disease and the titer is associated with the degree of infiltration and destruction of thyroid follicular.It is essential to monitor TPOAb in postpartum thyroiditis and early pregnancy.The positive of TPOAb is closely related to the adverse pregnancy outcomes caused by various risk factors.Graves disease combined with Hashimoto's must to be considered.

Objective To master of the characteristics of development and variation in plague natural foci of Marmota sibirica, and to analyze the plague monitoring results from 2004 to 2008. Methods From May to September every year, we monitored plague in Manzhouli, Chenbaerhuqi, Xinbaerhuzuoqi, Xinbaerhuyouqi,Ewenkeqi and Yakeshi city. The monitored area was 20 000 - 40 000 hm2 in every county. The density of Marmota,ground squirrel and moonlighting rats was surveyed by path method, one-day bow-clip method and a clamp was placed every five meters, respectively. The classification and identification of ectoparasite fleas were done by using low power lens. The fleas in the ground squirrel hole were collected by flannel rubber stick, then classified and identified. According to National Standard of Plague Diagnostic Criteria(GB 15991-1995), the collected rats and fleas were detected by isolation and cultured Yersinia pestis, the serums of collected rats were tested by indirect hemagglutination test. Results In five years, the density of Marmota and ground squirrel was 0.010/hm2 and 0.602/hm2, respectively. The capture rate of moonlighting rats was 2.69% (258/9600). The flea infection rate of Marmota was 17.54%(10/57) and the fleas index was 2.54. The fleas infection rate of ground squirrel was 28.40%(213/750) and the fleas index was 1.01. Flea infection rat of ground squirrel hole was 5.60%(46/822) and the fleas index was 0.17. The total number of various hosts of Yersinia pestis detected was 1351, the groups number of the variety of cultured fleas was 127, and the pathogen test results were negative. The number of serum tested was 1064, positive number was 43, and the detection rate was 4.04%(43/1064). The highest positive titer was 1 : 1280. Other than 2006, the remaining four years were found positive for blood clotting material; positive serum was found in a total of three regions, they were Manzhouli, Xinbaerhuzuoqi, and Xinbaerhuyouqi; and 30, 12 and 1 copies of hemagglutination-positive sera were detected. Conclusions The epidemic of plague natural foci of Marmota sibirica is in a active state, and gradually expands the scope. We must continue to strengthen the inspection of the bacteria, bearing in mind the replacement of the region's main host, make every effort to prevent and control of human plague.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are conveniently cultured and separated in vitro because theirimmunogenicity is low. Therefore, BMSCs are suitable for cell transplantation. Research has shown that BMSCs are potential to repair neurological defect. OBJECTIVE: To determine whether in vitro cultured BMSCs can be transplanted to repair peripheral nerve injury or not, and to investigate its mechanisms. DESIGN, TIME AND SETTING: Randomized controlled animal study This study was performed in Department of Toxicology, Public Health College of Jilin University from March 2006 to March 2007.MATERIALS: Fifty healthy female Wistar rats aging 2 months and six 1-week-old female Wistar rats were used for extraction of BMSCs. Rabbit-anti-nerve growth factor (NGF) monoclonal antibody was provided by Santa Cruz Company. METHODS:BMSCs were separated and cultured with adherent method. In the 3rd generation, BMSCs were preiabeled with bromodeoxyuridine (BrdU) 48 hours before transplantation. Fifty healthy Wistar rats were selected to prepare sciatic nerve crush injury models with clamping method.Subsequently, rats were randomly divided into transplantation group and control group, with 25 rats in each group. Rats in the transplantation group underwent transplantation of BrdU-labeied BMSCs at nerve injured sites; while, the same volume DMEM was injected into rats in the control group. MAIN OUTCOME MEASURES: Injured nerve in the transplantation group suffered from anti-BrdU staining 1, 2, 4, and 6 weeks after surgery. Distal injured nerve in both groups suffered from NGF immunohistochemical staining 1, 2, 4, and 6 weeks after surgery. Image analysis system was adopted to analyze integrated absorbance of positive expression. Gait analysis was performed every week after surgery to measure sciatic nerve function index, and it was also adopted to measure regenerated nerve conduction velocity 6 weeks after surgery. Subsequently, amount and inner diameter of medullated nerve fibers were calculated after luxol fast blue staining, while wet weight of experimental-lateral gastrocnemius muscle and cross section area of muscle fiber were measured at the same time. RESULTS: Fifty rats were included in the final analysis. BrdU-labeled positive cells could be found at injured nerve in the transplantation group 1, 2, and 4 weeks after surgery. Integrated absorbance of NGF protein expression in the transplantation group was significantly higher than that in the control group 1 and 2 weeks after surgery (P < 0.01), but there were no significant differences between the two groups 4 and 6 weeks after surgery (P > 0.05). Sciatic nerve function index in the transplantation group superiorly recovered to that in the control group 3-6 weeks after surgery. Furthermore, 6 weeks after surgery, nerve conduction velocity, amount and diameter of medullated nerve fibers, wet weight and cross section area of gastrocnemius muscle in the transplantation group were significantly higher than those in the control group (P < 0.05-0.01). CONCLUSION: BMSCs can be transplantated into injuried nerve tissue, and promote the recovery of nerve function in the micro-enviroment, improve NGF expression in an early phase may be one of its mechanisms.

Immobilization conditions of Candida tropicalis to be absorbed in polyurethane foam carrier materials were studied on the xylitol production from corn hemicellulosic hydrolysate. Optimum batch-fermentation conditions were as follows: inoculum amount, 7% (volume ratio); polyurethane foam quantity, 1.0 g/100 mL; 30?C; initial pH, 6.0. Shaking speed was divided into two-phase to accommodate the dissolved oxygen, with 200 r/min at 0~24 h and 150 r/min at 24 h~46 h. The immobilized cells on polyurethane foam carrier have high density and good resistance to inhibitors in the hydrolysates. Average xylitol yield and volumetric productivity of polyurethane foam immobilized fermentation were much higher than the fermentation without immobilization. Corn cob hydrolysates can be directly biotransformed to xylitol without decoloration or ion-exchange treatment. This process can effectively reduce production costs, and it shows broad prospects of applications. Average xylitol yield was 67.6% and xylitol volumetric productivity was 1.92 g/(L?h).
