Objective To investigate the relationship between Post stroke depression (PSD) and Post stroke cognitive impairment (PSCI) using proton magnetic resonance spectroscopy.Methods 82 patients of acute stroke,which were met with the third edition of the Chinese Classification of Mental Disorders (CCMD-Ⅲ) and expert consensus of cognitive impairment since January 2012 to December 2012,Select continuously 82 patients who are hospitalized in our hospital due to acute stroke from January 2012 to December 2012 from Zhongnan Hospital of Wuhan University,were examined by 1H-MRS in one month.They were divided into PSD and PSCI simultaneously (n =19),PSD (n =21),PSCI (n =22) and control group (n =20).Results The differences between PSD and PSCI was not significant.On hippocampus japonicas,the Cho/Cr ratio in patients of A group (left (1.05 ± 0.10),right(1.18 ± 0.15)),showed higher than those in B group (left (0.84 ± 0.10),right (0.88 ± 0.08)),C group (left(0.88 ±0.08),right (0.87 ±0.07)),D group(left(0.87 ±0.06),right(0.89 ±0.06)).The difference was statistically significant.PSD and PSCI promoted each other in influencing Cho/Cr ratio.Conclusion There is no significant relationship between PSD and PSCI in the produce of disease,and they can promote each other in hippocampus japonicas Cho/Cr ratio.

Objective To investigate the relationship between heat shock protein 72 (HSP72) and liver fibrosis in pediatric patients with biliary atresia and the significance of its expression.Methods The clinical and pathological data of 30 patients with biliary atresia were selected from June 2013 to June 2015,and the expression of HSP72 in liver tissues was determined by streptomycin peroxide (SP) immunohistochemical method.Results The greater group of liver fibrosis degree with biliary atresia was less than the lighter group in the expression of HSP72 (Z =-4.16,P ＜ 0.01).There was negative correlation between HSP72 expression intensity and operation age (r =-0.704,P ＜ 0.01).Meanwhile,there was negative correlation between HSP72 expression intensity and postoperative cholangitis (r =-0.371,P ＜ 0.05).When the expression of HSP72 was higher,the autologous liver survival rate was higher (x2 =9.482,P ＜ 0.01).Conclusions The expression of HSP72 in liver tissues of patients with biliary atresia is closely related to the degree of liver tissue fibrosis.HSP72 expression may be one of the factors affecting the prognosis of patients with biliary atresia,and can be used as a reference index for evaluating prognosis.

Objective To explore the clinical characteristics, surgical methods and outcome of recurrent retinal detachment in silicone oil-filled eyes after vitreoretinal surgery. Design Retrospective, observational case series. Participants 55 patients (55 eyes) diagnosed as recurrent retinal detachment with silicone oil-filled eyes. Methods To analyze the clinical manifestations of recurrent retinal detachments and adopt different methods to make retina reattach including vitreoretinal surgery with or without silicone oil removal and scleral buckle revision alone. Patients were followed up for 3 months. Main Outcome Measures Clinical manifestations, retinal re-attachment and visual acuity. Results The characteristics of recurrent retinal detachment in silicone oil-filled eyes were inferior location mainly, less than 2 quadrants, with proliferation and hole. Fifty of the 55 patients underwent repeat surgical repair. Surgical methods included re-vitreoretinal surgery in 39 eyes with silicone oil removal, re-vitreoretinal surgery in 9 eyes without silicone oil removal and scleral buckle revision alone in 2 eyes. After a follow-up of 3 months, retina re-attached in 41 eyes, partially attached in 7 eyes, and detached in 2 eyes. Conclusions Repair of recurrent retinal detachment in silicone oil filled eye is challenging. Favorable anatomic outcome may be achieved in selected patients with proper surgical measures according to the characteristics of recurrent retinal detachment.

A 54-year-old woman presented with a five-year history of malaise with weight loss and arthralgia of both knee joints. Six months prior to the presentation, an indurated nodule developed at the site of an old scar on the temporal side of left eyebrow. Subsequently, erythema and nodules spread over the trunk and extremities, especially at the sites of old scars on the hands. Physical examination showed bilateral axillary lymphadenectasis, a plaque at the site of an old scar on the temporal side of left eyebrow, a subcutaneous mass at the extensor aspect of the right upper arm, multiple dark-erythematous nodules at the site of scars on the left hand and both soles, few small erythematous papules scattered on the left forearm and trunk. The serum angiotensin converting enzyme concentration was high (82 kU/L). Computer tomography of thorax showed multiple obscure tubercles in both lungs and swollen lymph nodes in mediastina and axillary fossa, but no hilum pulmonis lymphadenectasis was observed. Histopathology revealed non-caseating granulomas with multinucleated giant cells. Neither acid-fast bacilli nor PAS staining was positive. A diagnosis of scar sarcoidosis was established. The lesions obviously improved after one-month treatment with oral methylprednisolone. This case represents a rare subtype of sarcoidosis that arose in old sears and clinically manifests as scar, nodules,plaques, subcutaneous masses and papules. The reactivation of old scars, which manifests as erythematous swelling and nodules, may highly suggest the diagnosis of sarcoidosis.

Objective To investigate the influence factors of malnutrition risk in hospitalized children,in order to provide theoretical basis for early identifying hospitalized children at the risk of malnutrition and for guiding clinical nutritional intervention.Methods Hospitalized children in the Department of Pediatrics of our hospital from March 1st 2013 to April 30th 2014 were included and assessed using Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP).Questionnaire survey was conducted and clinical data was recorded.The children were divided into two groups according to STAMP scores upon admission,namely high malnutrition risk group and low malnutrition risk group.Comparing the differences of basic characteristics,laboratory examinations,and treatments between the two groups,associated factors of statistical significance were detected.With the associated factors identified in single factor analysis as independent variables and STAMP score-based group division as the dependent variable,multifactor unconditional Logistic regression analysis was performed to explore the independent risk factors influencing STAMP scores of hospitalized children.Results A total of 1 406 hospitalized children were included,of whom 738 were at high malnutrition risk,and the other 668 were at low malnutrition risk.Single factor analysis indicated that fever before admission (Z =-3.809,P =0.000),severity of condition (x2 =14.068,P =0.000),age (x2 =5.813,P =0.017),and length of fever before admission (t =2.793,P =0.005) were associated with high malnutrition risk of hospitalized children.Non-conditional Logistic regression suggested that severity of condition (OR =1.557,95％ CI:1.164-2.083,P =0.003),length of fever before admission (OR =1.039,95％ CI:1.011-1.068,P =0.006),and granulocyte count (OR =1.032,95％ CI:1.004-1.061,P =0.027) were risk factors of high malnutrition risk in hospitalized children,and age (OR =0.942,95％ CI:0.909-0.977,P =0.001) was protective factor.Conclusion Age,severity of condition,length of fever before admission,and granulocyte count can provide helpful information for early identification of hospitalized children at high malnutrition risk.

Objective To investigate the relationship between HBV DNA load with the serological markers(HB-M)HBsAg, HBeAg,HBeAb,HBcAb in the persons infected by chronic hepatitis B virus (HBV)in Lanzhou.Methods The real-time fluores-cent quantitative PCR was used to detect the HBV DNA load and the double antibody sandwich chemiluminesent immunoassay was used to measure the serum HBsAg,HbeAg,HbeAb and HbcAb levels in 724 cases of HBVinfection.Results The HBsAg level was positively correlated with the HBV DNA load in chronic HBV infection in Lanzhou area(r=0.342,P <0.05),there was an ob-vious positive correlation between HBeAg and HBV DNA load(r=0.463,P <0.05),the HBeAb level and HBV DNA load had the negative correlation (r=-0.227,P =0.001),the HBcAb level and HBV DNA load had no significantly correlation (r=-0.062, P =0.366).Conclusion There is obvious positive correlation between HBV DNA load with HBsAg,HBeAg in chronic HBV infec-tion in Lanzhou area,which indicating that the observation by combining HBsAg and HBeAg with HBV DNA can judge the infec-tious degree of the patients more accurately.

Objective To investigate the value of MR diffusion-weighted imaging (DWI) in differentiating pancreatic carcinoma from chronic focal pancreatitis on 3.0 T MR system. Methods Thirteen patients with proved pancreatic carcinoma, 7 patients with confirmed chronic focal pancreatitis, and 14 healthy volunteers, were included in this study. MR examination including the routine abdomen scanning protocol and DWI was performed for both patients and volunteers. The SE-EPI sequence and ASSET technique were used for DWI. The b values of 400, 600, 800 and 1 000 s/mm2 were selected to acquire the DWI. The corresponding apparent diffusion coefficient (ADC) values were measured in each designated region of interest and statistically analyzed. Results ①DWI of the healthy volunteers showed intermediate signals of pancreas. ②DWI of pancreatic tumor masses showed homogenous high signal intensity relative to the surrounding pancreatic tissue with clear boundary. Under different b values, the tumor ADC values were (1.63?0.235)?10-3 mm2/s, (1.42?0.126)?10-3 mm2/s, (1.36?0.170)?10-3 mm2/s and (1.26?0.178)?10-3 mm2/s respectively, which were significantly lower than those of non-tumor region (2.11?0.444)?10-3 mm2/s, (1.83?0.230)?10-3 mm2/s, (1.81?0.426)?10-3 mm2/s, (1.60?0.230)?10-3 mm2/s and of the normal pancreas (1.85?0.350)?10-3 mm2/s, (1.69?0.290)?10-3 mm2/s, (1.67?0.268)?10-3 mm2/s, (1.42?0.221)?10-3 mm2/s, P

Objective To investigate the difference of serum prealbumin in hospitalized children and its value in Screening Tool for the Assessment of Malnutrition in Pediatrics ( STAMP) in hospital-izedchildren.Methods 867hospitalizedchildrenwererecruitedfromMarch2013toApril2014in the First Affiliated Hospital of Fujian Medical University .All the patients were assessed using STAMP and collected venous blood sample for measuring serum prealbumin within 24 hours after admission.All the patients were surveyed for information regarding gender , age, dietary changes, etc.and their clini-cal data and laboratory results during hospitalization collected .The patients were divided into high mal-nutrition risk group ( HMRG) and low malnutrition risk group ( LMRG) according to STAMP scores upon admission. Results There were 463 children ( 53.4%) in HMRG, and 404 in LMRG (46.6%).Compared with the LMRG, the HMRG had significantly lower serum prealbumin [ (144.7 ± 50.6) mg/L vs.(173.6 ±71.3) mg/L, t=6.795, P=0.000].After controlling for age, course of disease, white blood cell count, albumin, glutamic-oxalacetic transaminase, C-reactive protein in covariance analysis, the HMRG still had significantly lower serum prealbumin than the LMRG [ estimate ( 95% CI): 139.8 ( 134.9 -144.8 ) mg/L vs.157.9 ( 151.9 -163.8 ) mg/L, F =20.433 , P=0.000 ) .Clinical cure rates in HMRG with low serum prealbumin , HMRG with normal serum pre-albumin, LMRG with low serum prealbumin, and LMRG with normal serum prealbumin were 62.9%(95/151), 80.5% (251/312), 77.1% (27/35), and 98.1% (362/369) (χ2 =112.80, P=0.000 ) , respectively; incidences of hospital acquired infection were 21.9% ( 33/151 ) , 8.7%( 27/312 ) , 22.9% ( 8/35 ) , and 1.9% ( 7/369 ) (χ2 =63.55 , P =0.000 ) , respectively. Conclusion High malnutrtion could be distinguished more accurately using the combination of the as-sessment of malnutrition screening tools and serum prealbumin measurement .
