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 evaluate the application value of serum endotoxin combined with integrated model for end-stage liver disease (iMELD) in evaluating the short and medium term prognosis of patients with decompensated liver cirrhosis.Methods The clinical data of 68 patients with decompensated liver cirrhosis were retrospectively analyzed.The patients were divided into survival group and death group according to the result of follow-up at the 3,6 and 12 months.The iMELD score and Child-Turcotte-Pugh (CTP) score were calculated according to relevant indicators,and the serum endotoxin level was detected.The correlation between serum endotoxin and iMELD score was analyzed in the short and medium term prognosis in patients with decompensated liver cirrhosis.Results After 3 months' follow-up,5 patients died.The iMELD scores in survival group and death group were (39.26 ± 7.29) and (49.29 ± 8.63) scores,CTP scores were (9.32 ± 2.12) and (12.03 ± 2.75) scores,serum endotoxin levels were (9.21 ± 2.24) and (15.39 ± 5.12) ng/L,and there were statistical differences (P ＜ 0.05).After 6 months'follow-up,12 patients died.The iMELD scores in survival group and death group were (41.35 ± 8.03) and (52.18 ± 10.37) scores,CTP scores were (9.78 ± 2.05) and (12.93 ± 1.99) scores,serum endotoxin levels were (8.96 ± 2.41) and (16.43 ±6.03) ng/L,and there were statistical differences (P ＜0.05).After 12 months' follow-up,19 patients died.The iMELD scores in survival group and death group were (40.74 ± 6.38) and (52.29 ± 8.53) scores,CTP scores were (10.01 ± 2.23) and (13.27 ± 1.69) scores,serum endotoxin levels were (8.53 ± 2.34) and (16.52 ± 6.08) ng/L,and there were statistical differences (P ＜ 0.05).The area under curve of receiver operating characteristic (ROC) was 0.952,standard error was 0.048,and 95％ confidence interval was 0.790-1.022.The best critical value of iMELD score to predict death was ≥48.00 scores,and the risk of death would rise if iMELD score was increased.The best critical value of serum endotoxin to predict death was ≥ 11.00 ng/L.Conclusion iMELD score and serum endotoxin have important value in predicting prognosis in patients with decompensated liver cirrhosis.

The authors give an account of the basic concept and classification of cytotoxic drugs. A center for compounding cytotoxic drugs has been set up in their hospital by using for reference the management experience of the US in this aspect. The center stresses centralized management in compounding cytotoxic drugs, strict operating rules and protective actions, and reduction of possible toxic damages resulting from cytotoxic drugs and infection caused by them in other sectors, thus guaranteeing the physical and mental health of the medical staff. At the same time, the authors call on all medical institutions to pay attention to the disposition of cytotoxic drugs and exert efforts to help a relevant national standard to come out as soon as possible.

Objective To develop a new type fusion apparatus for scaphoid-trapezium-trapezoid (STT) arthrodesis.Methods The apparatus was designed on the basis of the anatomic data of STT measured from Chinese cadaveric wrists.Simulated arthrodeses of STT joints were conducted to test the fixation performance of the apparatus made of titanium alloy on the STT joint specimens.Several modifications were made before the apparatus was made into a finished product.Results The fusion apparatus consists of a plate and screws.The fusion plate for STT arthrodesis is made into a taper one connected to a cylinder.On the plate are three screw holes through which the three carpal bones (STT) are fixed by three screws respectively.The hollow cylinder is designed for bone grafting,and its outer threads ensure a very tight contact between the fusion plate and the carpal bones.Auxiliary tools are also made.Conclusions As the novel design of the fusion apparatus improves the mechanical strength of fixation of STT and prevents the possible rotation and collapse of fused STT,the apparatus is a reliable internal fixation device for the limited intercarpal arthrodesis.

Objectives: To investigate the occurrence and risk factors of cerebral microbleeds on the cognitive function in patients with ischemic cerebrovascular disease and to investigate the effect of cerebral microbleeds on the cognitive function in patients with ischemic cerebrovascular disease. Methods: A total of 160 patients with ischemic cerebrovascular disease were divided into cerebral microbleed group (n =30) and control group (n = 130) according to MR T2 *-weighted gradient echo sequences. The demographic data of the patients, conventional risk factors, sites of microbleed, types of cerebral infarction, severity of white matter changes, and numbers of lacunar infarction were recorded in detail. The Montreal Cognitive Assessment was conducted in both groups. All the data were processed using SPSS 16.0 software. Results: Circled digit oneThe mean age of the microbleed group was older than that in the non-microbleed group (75 ±9 vs. 66 ±6, P = 0.000) ; the degree of white matter changes was higher (6.7 ±2.4 vs. 3.5 ±1. 8, P =0.003) ; and the numbers of lacunar infarction were larger (5.0 ±2. 3 vs. 2. 1 ±1.3, P= 0.000). Circled digit twoThe logistic regression analysis showed that the high blood cholesterol, the degree of white matter change ( WMC ) , and the numbers of lacunar infarction were the independent risk factors for CMB (OR =3. 880, 95% CI:0. 086 -0. 994; OR = 11.735, 95% CI; 1.340 -2.930; OR = 10. 160, 95% CI: 1.241 -2.475). Circled digit threeThere was no significant difference in the cognitive function scores between the two groups ( P > 0. 05 ). Circled digit fourThere was significant difference in the executive ability between the two groups (P =0.010). Conclusions: Circled digit oneCerebral microbleeds are closely associated with leukoaraiosis and lacunar infarction; Circled digit twothe patients with ischemic cerebrovascular disease accompanied by microbleeds has obvious executive dysfunction ; Circled digit threecontrolling the risk factors for microbleeds has a certain role for the control of the occurrence and development of cognitive impairment in patients with ischemic cerebrovascular disease.

Objective:To investigate the correlation between sarcopenia and post-stroke cognitive impairment(PSCI)in elderly patients with first-time acute minor ischemic stroke.Methods:This was a prospective study.Elderly patients over 60 years of age with first-time acute minor ischemic stroke admitted to the Department of Neurology of the General Hospital of Western Theater Command from October 2018 to June 2019 were continuously enrolled.Patients received the SARC-F score assessment within 24h after admission and were divided into two groups according to their SARC-F scores: the non-sarcopenia group(SARC-F score<4)and the sarcopenia group(SARC-F score≥4). Cognitive function was assessed by using the Mini-Mental State Examination(MMSE)within 24 h of admission and at 3-month follow-up.Results:A total of 211 patients were enrolled in this study, including 31 patients(31/211, 14.69%)in the sarcopenia group and 180 patients(180/211, 85.31%)in the non-sarcopenia group.The incidence of PSCI was higher in the sarcopenia group than in the non-sarcopenia group(83.87% or 26/31 vs.55.56% or 100/180, χ2=8.814, P=0.003). The total MMSE score, orientation, immediate memory, attention, calculation and language functions were lower in the sarcopenia group compared with non-sarcopenia group( P<0.05). Logistic regression analysis showed that sarcopenia was an independent risk factor for PSCI( OR=3.478, 95% CI: 1.039-11.642, P=0.043)in the elderly with first-time acute minor ischemic stroke. Conclusions:Sarcopenia is an independent risk factor for PSCI in elderly patients with first-time acute minor ischemic stroke.Sarcopenia assessment in the acute phase of stroke might help doctors to assess the risk of PSCI and reduce the incidence of PSCI in stroke patients.

AIM: To study the effect and mechanism of BCG on human nature killer cells. METHODS: PBMC or purified NK cells were isolated from normal human peripheral blood with negative anti-Mycobacterium tuberculosis antibody and cultured with BCG, IL-12, BCG plus IL-12 and BCG plus anti-IL-12Rβ1 mAb (2B10), respectively. The levels of IFN-γ and IL-12p40 in the culture supernatants were measured by ELISA. The frequency of IFN-γ and granzyme B producing cells were analyzed by ELISpot. The cytolytic activity was detected by MTT reduction assay. The surface expression of IL-12Rβ1 on NK cells was detected by flow cytometry. RESULTS: BCG significantly induced IFN-γ production by PBMC in a dose-dependent manner. When PBMC was stimulated with BCG, the frequency of granzyme B producing cells was higher than that in unstimulated PBMC (P<0.05). BCG enhanced the cytotoxic activity of PBMC. BCG alone didn' t induce IFN-γ production by purified NK cells, but it can augment IL-12-induced IFN-γ production by purified NK cells. The cytotoxic activities of BCG-stimulated and unstimulated purified NK cells were not significantly different (P>0.05). BCG induced IL-12 production by PBMC in a dose-dependent manner and enhanced IL-12Rβ1 expression on different subsets of NK cells. Blocking the effect of IL-12 by anti-IL-12Rβ1 mAb (2B10) inhibited BCG-induced IFN-γ production and granzyme B releasing by PBMC. CONCLUSION: BCG can indirectly promote biologic activity of NK cells and the production of endogenous IL-12 combined with up-regulation IL-12Rβ1 expression on the surface of NK cells is a part of the mechanisms of IL-12 on human NK cells.
