Objective To explore neglect dyslexia in unilateral spatial neglect patients,the error type and whether there exists word length and semantic effect.Methods Ten left spatial neglect patients were investigated by Chinese characters reading material.Results Unilateral spatial patients showed neglect dyslexia (202 neglect errors,94.0％ of the total 215 errors) when reading.The most common errors were omissions (148 errors,73.3％ of the total 202 neglect errors),followed by substitutions and additions.The error rate of two words was 9.9％ ± 8.4％,while the rate of three words was 18.8％ ± 16.2％.Performance was worse with the increase of word length (T =-55,P ＜ 0.05).The error rate of words was 8.3％ ± 7.5％,while the rate of non-words was 18.9％ ± 16.6％,and the rate of non-words was worse than that of words (T =-55,P ＜ 0.05).Conclusions Our study has shown that omissions are the most common error type of neglect dyslexia in Chinese unilateral spatial neglect patients,and the impairment include word length effect.The patients with unilateral spatial neglect show preserved semantic processing in the neglect side.

Objective To discuss the nonoperative management strategy to prevent the conversion of acute pancreatitis to the severe form.Methods In recent 4 years,286 patients with mild acute pancreatitis admitted to our hospital were divided into control group and treatment observation group;routine conservative management was performed in control group,and the strategy of improving pancreatic microcirculation and preventing cell Ca~2+ overload and inhibiting pancreatic protease was added to the treatment observation group.Results Among the 144 patients with mild acute pancreatitis in control group,conversion to severe acute pancreatitis occurred in 20 patients,and 14 of the 20 patients with severe acute pancreatitis developed systemic complications.Among the 142 cases in treatment observation group,the conversion of mild to severe acute pancreatitis occurred in 8 patients,and 2 of the 8 patients developed systemic complications.Serum C-reactive protein levels and Balthazar CT severity index were significantly decreased at each time point in treatment observation group compared to control group.Conclusions In addition to routine management,improving pancreatic microcirculation,preventing cell Ca~2+ overload and inhibiting pancreatic protease might serve as a benificial strategy for preventing the progression of mild acute pancreatitis to the severe form.

Objective To assess the clinical value of HRCT in diagnosis of cholesteatomatous tympanitis.Methods HRCT findings of 26 patients with cholesteatomatous tympanitis proved by surgery and pathology were analyzed.Results HRCT findings of cholesteatomatous tympanitis included:soft tissue mass in the superior tympanium,tympanal sinus and mastoid(100%,26/26),destruction of the bone includeing ossicles chain (92%,24/26),secutum(46%,12/26),facial nerve canal (54%,14/26);enlargement of the tympaniosinus with sclerosing borders;intracranial complications including temple abscess(1 case),meningitis(1 case).Conclusion HRCT is of great value in diagnosis of cholesteatomatous tympanitis.

OBJECTIVETo study the effects and possible mechanisms of TCM treatment for purging fire, removing toxic substance, relieving stagnation and eliminating phlegm on cytoplasmic free calcium ([Ca2+]i) and intercellular adhesion molecule-1 (ICAM-1) in rats with intracerebral hemorrhage (ICH).

METHODSAdult SD rats were randomly divided into six groups: the normal group, the operated group, the model group, the Naoqing Decoction (NQD) low- and high-dose groups, and the Qingkailing Injection (QKL) group. ICH model was induced by injecting collagenase into right caudate nucleus, level of [Ca2+]i was determined by fluorescent tracing assay, and the expression of ICAM-1 was determined using immunohistochemical technique.

RESULTSHigh- and low-dose of NQD and QKL could significantly antagonize the collagenase injection induced increase of [Ca2+]i (P < 0.01), inhibit the expression of ICAM-1 and shorten its sustainable time.

CONCLUSIONNQD plays a role in protecting neuron by inhibiting calcium overload, regulating cytokines network, and inhibiting inflammatory reaction through postponing the release of cytokines and inflammatory mediators.

Objective To investigate the efficacy, safety and prevention of complications of haploidentical allogeneic hematopoietic stem cell transplantation (Haplo-HSCT) in patients with severe aplastic anemia (SAA). Methods The clinical data of 8 SAA patients treated with Haplo-HSCT were retrospectively analyzed, with male in 5 cases, female in 3 cases, and an average age of 14 years. The donors of hematopoietic stem cells were patient′ s parents. The preparative regimen was cyclophosphamide + fludarabine + anti-human lymphocyte immune globulin, and 2 patients combined with total body irradiation. The recipients received cyclosporine, short- term methotrexate and mycophenolate mofetil (MMF) for preventing graft versus host disease (GVHD). The hematopoietic reconstitution, the chimerism rate of donor cells, and the incidence of postoperative complications such as infection, GVHD, liver veno- occlusive disease (VOD), hemorrhagic cystitis (HC), and cytomegalovirus (CMV) were observed. Results Hematopoietic reconstitution was achieved in all the 8 patients, the neutrophil engraftment time was (14.80 ± 3.24) d, and the platelet engraftment time was (15.00 ± 3.42) d. One month after transplantation, all the patients had complete DNA chimerism. Seven patients occurred acute GVHD, includingⅠ-Ⅱgrade in 5 cases, Ⅲgrade in 1 case, andⅣgrade in 1 case. Two patients occurred chronic GVHD, including 1 case with localized GVHD in the oral cavity and 1 case with extensive type chronic GVHD in the whole body skin. No liver VOD or HC occurred. No transplantation-related death occurred at average follow-up time of 8.5 (2 - 18) months. Conclusions Haplo-HSCT is safe and effective in patients with SAA.

Objective To investigate the gestation-specific reference intervals (GRIs) and dynamic changes of thyroid function at different gestational ages in Chongqing .Methods Combining self-sequential longtitudinal with cross-sectional study, the serum samples from 640 pregnant women with different gestational age were collected from June 2014 to September 2015 in the Third Military Medical University. The free triiodothyronine (FT3), free thyroxine (FT4), thyroglobulin (TG), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), and antithyroglobulin antibody (TGAb) were detected by the direct chemiluminescence method.According to China Guideline for the diagnosis and treatment of thyroid disease in pregnancy and postpartum in 2012, the reference interval of the thyroid function was calculated.The data were analyzed by Chi square test .Results Established GRIs of thyroid function during pregnancy in Chongqing:The GRIs was 3.68-5.59 pmol/L for FT3, 9.34-17.02 pmol /L for FT4, 0.18-5.26 mIU/L for TSH in 6-9+6 weeks of pregnancy; the GRIs was 3.69-6.03 pmol /L for FT3, 8.42-15.75 pmol/L for FT4、0.09-4.85 mIU/L for TSH in 10-13+6 weeks of pregnancy; the GRIs was 3.24-5.46 pmol /L for FT3, 6.50-14.24 pmol/L for FT4, 0.11-5.13 mIU/L for TSH in 14-27+6 weeks of pregnancy;the GRIs was 3.06-5.05 pmol /L for FT3, 6.12-11.69 pmol/L for FT4, 0.75-3.67 mIU/L for TSH in 30-34 weeks of pregnancy; the GRIs was 2.96-5.00 pmol/L for FT3, 6.26-11.36 pmol /L for FT4, 0.84-5.54 mIU/L for TSH in 36-40 weeks of pregnancy.Screening by GRIs, the prevalence of thyroid dysfunction was 8.75% (46), however, the prevalence was 37.07% (195) in according with the guidelines,χ2 =120.5,P =0.000.The overdiagnosis rate was 28.32%(149 /526).Using the guidelines of thyroid disease and our GRIs, the thyroid disease was found 116 (22.05%) and 30 (5.70%) in the first screening. Moreover, the thyroid disease was found 79(19.27%) and 10(3.23%) during the repeat screening in the normal population.Conclusions Using the GRIs for thyroid function tests in normal singleton pregnant women could reduce the risk of over diagnosis .The detection rate of repeat screening of TPOAb negative patients was close to the first screening detection rate , and repeated screening could reduce the risk of missed diagnosis for thyroid dysfunction in pregnancy women .(Chin J Lab Med, 2016, 39:511-515 )
