Autoimmune encephalitis is a group of inflammatory diseases related to autoantibodies that affect the central nervous system. Early diagnosis of patients with autoimmune encephalitis has certain difficulties, because the clinical manifestations caused by different types of autoantibodies can be non-specific, and the presence of multiple autoantibodies can cause variation and superposition of clinical manifestations. The article reported a case of autoimmune encephalitis patients with double positive anti-N-methyl-D-aspartate receptor and dipeptidyl-peptidase-like protein-6 antibodies, and reviewed relevant literature for clinical reference.

Objective To evaluate the biological safety of 125I-filled carbon nanotubes covered with metallic esophageal stent with regard to the normal esophagus before clinical application.Methods 125I-filled carbon nanotubes covered with metallic esophageal stent was prepared.Eighteen of New Zealand rabbits were randomly divided into three groups with 6 rabbits in each group.Three groups of stents,non-radioactive,low radio-activity ( 3.7 - 5.6 MBq),and high activity ( 11.1 - 13.0 MBq ) were placed in the midpiece of esophagus of rabbits.Esophagus opacification and three-diamensions DSA were performed at 0.5 h,7,14 and 30 d after insertion of the stents,respectively.The rabbits were killed at 30d after insertion of the stents,and histologic examinations of the esophageal walls were performed.Results In non-radioactive and low activity groups,1 of 6 rabbits died of wound infection at 1 and 3 d after surgery due to pulmonary infection,respectively.All specimens were obtained from 16 rabbits.Microscopically,in all rabbits of low activity and high activity groups,there were membrana mucosa necrotic and swell and breakage of the muscle fiber in esophageal submucosa and muscularis,submucosal inflammation,which were more severe in high activity group.In low activity group,one esophagus ectal membrane was involved,however,esophageal perforation did not develop.In high activity group,3 of 6rabbits esophageal perforation had developed,in which one esophagus mediastinum fistula developed,without inflammation.In non-radioactive group,it was almost normal in mucosa layer,a small amount of inflammatory cells were found in submucosal layer,and part of muscle fibers was fractured and no pathological changes of necrosis was found.Conclusions Radioactive 125I carbon nanotubes covered metallic stent with low activity(3.7 -5.6 MBq) can be used as intraluminal palliative brachytherapy,which is safe and effective.

This paper analyzed current problems and challenges facing hospitals in alarm management both abroad and at home. Based on a survey conducted on alarm management in hospitals, plus an analysis on different kinds of data interfaces and data exchange protocols of the medical equipment used in ICUs, a solution of alarm management is put forwarded which is based on alarm information integration and processing. It aims at improving medical equipment alarm management and reducing relevant adverse events.

Human factors engineering is a promising interdisciplinary subject in applied sciences.This study presented the development and research purposes of human factors engineering.Based on case studies,the authors probed into the importance of the engineering in the design,management and procurement of medical equipments,for the purpose of optimizing medical equipment design,manufacturing and procurement.

AIM: To test the effects of FTY720 on mouse intestinal allografts.METHODS: C_3H mice(H-2~k)were used as donor and C57BL/6 mice(H-2~b) as recipients.FTY720 group,allogeneic control group and isogeneic control group were set up.6 and 14 days after transplantation,murine intestinal grafts were harvested for histologic assessment.Lymphocytes were collected from mesenteric lymph nodes(MLN),Peyer's patch(PP),lamina propria lymphocytes(LPL) and intraepithelial lymphocytes(IEL) in the graft,then were analyzed by cytometry.RESULTS: Rejection was inhibited in FTY720 group at the 6th post-transplant day,although not at the 14th day.Recipient CD4~+ and CD8~+ T cells,CD19~+ B cells,as well as ?? TCR lymphocytes,were greatly reduced by FTY720 therapy.The similar action of FTY720 was also revealed in Gr1~+CD11b~+ monocytes.CONCLUSION: FTY720 is efficient on alleviating allo-immune response by reducing the infiltration of both lymphocytes and monocytes into the graft in a mouse intestinal transplantation model.

OBJECTIVETo study the therapeutic mechanism of Zhizhu Pill (ZP) for treating functional dyspepsia (FD) rats.

METHODSTotally 30 ten-day-old male rats were randomly divided into the normal control group (n =10) and the model group (n = 20). The FD rat model was induced using gastric administration of 0.1% iodoacetamide (IA) combined tail clamping. The model was evaluated when rats were 8-week old. Successfully modeled rats were randomly divided into the model group (n = 10) and the ZP group (n = 10). Rats in the normal group and the model group were administered with normal saline by gastrogavage, while those in the ZP group were administered with ZP Decoction (2 mL/100 g) by gastrogavage. All medication lasted for 7 successive days. The contractile activity in in vitro longitudinal gastric muscle was recorded using Power Lab biological signal collecting system. The expression of growth hormone secretagogue receptor (GHSR) in stomach of FD rats was detected using Western blot and immunohistochemistry (IHC).

RESULTSCompared with the normal group, average frequencies of gastric contraction and changing rates of amplitude obviously decreased in the model group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR decreased in the model group (P < 0.01). Compared with the model group, average frequencies of gastric contraction and changing rates of amplitude obviously increased in the ZP group (P < 0.05). Results of Western blot and IHC showed that the expression of GHSR increased in the ZP group (P < 0.01).

CONCLUSIONZP could promote the gastric motility in FD rats induced by gastric administration of IA combined tail clamping, and its mechanism might be related to up-regulating GHSR protein level.

The effect of osmotic pressure on nitrification was investigated in the internal-loop air-lift nitrifying reactor. When influent ammonia concentration is kept at 420mg x L(-1) and influent osmotic pressure is increased from 4.3 to 18.8 x 10(5) Pa, the ammonia conversion of the nitrifying bioreactor is maintained between 93% and 100%. After influent osmotic pressure is further increased to 19.2 x 10(5)Pa, the ammonia conversion goes down to 69.2%. The influence of osmotic pressure on nitrification takes place without any alarm and the critical osmotic pressure is between 18.8 x 10(5) and 19.2 x 10(5) Pa. During osmotic stress, the nitrifying bacterial populations in the activated sludge become simplified, the cell size becomes smaller, the inner membrane becomes less and some unknown inclusion particles are formed. The cell structure is restored as soon as the osmotic pressure is removed. Addition of potassium is able to relieve the effect of osmotic pressure on nitrification. The nitrifying activity of the activated sludge is stimulated by the osmotic stress, and the specific ammonia conversion is increased from 0.083 kg x kg(-1) x d(-1) to 0.509 kg x kg(-1) x d(-1) and 2.569 kg x kg(-1) x d(-1), respectively.

OBJECTIVE:To observe the bleeding,therapeutic efficacy and ADR of patients with acute cerebral infarction (ACI) treated by alteplase intravenous thrombolysis. METHODS:140 ACI patients were randomly divided into group A and B with 70 cases in each group. Group A was give alteplase 0.6 mg/kg for intravenous thrombolytic therapy,and group B was given al-teplase 0.9 mg/kg for intravenous thrombolytic therapy. The bleeding after thrombolysis,bleeding time,therapeutic efficacy and ADR were compared between 2 groups. RESULTS:The incidence of Subcutaneous ecchymosis,gingival bleeding,bleeding of di-gestive tract and intracranial hemorrhage of group A were 4.29%,2.86%,2.86% and 2.86%;those of group B were 14.29%, 12.86%,11.43% and 11.43%;the bleeding time of those symptomsin 2 groups were(6.04±0.75)and(7.22±0.56)h、(24.63± 10.24)and(35.22±9.87)min、(3.04±0.11)and(4.08±0.25)h、(3.12±0.48)和(4.53±0.66)h respectirely,with statistical signifi-cance(P<0.05). There was no statistical significance in therapeutic efficacy and ADR between 2 groups after treatment(P>0.05). CONCLUSIONS:The bleeding should be monitored strictly when ACI patients receive alteplase intravenous thrombolysis,and low-dose alteplase thrombolysis can ultimately reduce the incidence of bleeding.
