Objective To explore the clinical significance of urine transferrin testing in the diagnosis of early pregnancy-induced hypertension syndrome (PIH).Methods Sixty-eight PIH patients (PIH group) who received treatment from January 2012 to October 2013 were enrolled in this study.Mild PIH was 21 patients,midrange PIH was 24 patients and severe PIH was 23 patients.Meanwhile,68 cases of healthy person were selected as control group.The level of urine transferrin,urea and creatinine were compared between two groups.Results The level of urine transferrin,urea and creatinine in PIH group were significantly higher than those in control group[(3.01 ± 1.82) mg/L vs.(1.29 ± 0.88) mg/L,(13.12 ± 5.51) mmol/L vs.(6.23 ± 3.68) mmol/L,(135.5 ± 62.3) μ mol/L vs.(85.1 ± 38.2) μ mol/L] (P ＜ 0.05).The sensitivity of urine transferrin,urea and creatinine in mild PIH was 76.19％,61.90％,57.14％.In midrange PIH was 75.00％,79.17％,75.00％.In severe PIH was 78.26％,86.96％,73.91％.The specificity of urine transferrin,urea and creatinine was 80.65％,56.45％,58.06％.The sensitivity of different degree of PIH was exceeded 75.00％.The sensitivity of urine transferrin in mild PIH was significantly higher than urea and creatinine (P ＜ 0.05).But the sensitivity of urine transferrin in midrange PIH and severe PIH had no significant difference (P ＞ 0.05).The specificity of urine transferrin was significantly higher than urea and creatinine (P ＜ 0.05).Conclusions Urine transferrin is a good index in diagnosis of early PIH,which can reflect the early injury degree of the renal tubular and glomerular.It has active and important significance for the clinical diagnosis and treatment of PIH.

In order to explore the dose-response patterns of Gancao (Radix Glycyrrhizae) in Shanghan Lun (Treatise on Febrile Diseases), all prescriptions containing Gancao in Shanghan Lun were analyzed by frequency and hierarchical clustering analysis. The doses of Gancao used in Shanghan Lun ranged from six zhu (Chinese unit, and one zhu is equal to 0.65 g) to four liang (Chinese unit, and one liang is equal to 15.625 g). Doses of one, two, three or four liang were commonly used. One liang Gancao as juvantia was usually matched with Mahuang (Herba Ephedrae), Xingren (Semen Armeniacae) and Guizhi (Ramulus Cinnamomi) for restricting the excessive diaphoresis of Mahuang. Two liang Gancao was often matched with some couple drugs, such as Guizhi and Shaoyao (Radix Paeoniae), Shigao (Gypsum Fibrosum) and Zhimu (Rhizoma Anemarrhenae), Fuzi (Radix Aconiti Lateralis) and Ganjiang (Rhizoma Zingiberis), for warming yang to supplement qi, nourishing yin, detoxifying Fuzi, and preventing qi impairment from heat evil. Three liang Gancao was mainly matched with Banxia (Rhizoma Pinelliae) or Renshen (Radix Ginseng) for treating middle energizer emesis. Four liang Gancao was matched with Ganjiang or tonifying herbs for invigorating vital qi and relieving spasm in deficiency syndromes with contraction, palpitation or diarrhea. Gancao is used for treating many syndromes in Shanghan Lun. It is frequently used to treat excess or heat syndromes with one or two liang in a dose and deficiency or cold syndromes with three or four liang in a dose.

Objective To analyze the clinical features of 385 postoperative thyroid nodules patients,and to compare the correlation affected by different factors between benign and malignant thyroid nodules.Methods Total 385 patients underwent thyroid operation in general surgery department of our hospital were enrolled.Their clinical data,ultrasonic scanning of thyroid,and pathological results were compared between benign and malignant thyroid nodules.Results (1)264 cases with benign nodules (68.57％) and 121 cases with malignant nodules (31.43 ％)were found among 385 cases.The average age of benign group was (48.1 ± 13.4) years old,while malignant nodules group was (45.6 ± 12.5) years old.(2) No gender difference was found between benign and malignant nodules group (P＞0.05).(3) According to body mass index (BMI),the highest prevalence of malignant nodules was in overweight group,followed by obesity group.(4) Fasting blood glucose was (5.61 ± 1.07) mmol/L in benign group and (5.86±1.21) mmol/L in malignant group(P＜0.05).(5) Thyroid-stimulating hormone (TSH) in benign nodules group was (1.62 ± 1.30) mIU/L,while in malignant nodules group,which was (2.02 ±2.59) mIU/L(P＜0.05).(6) Irregular shape,unclear boundary,calcification,and lymph node metastasis were more frequent in malignant group than those in benign group under ultrasonic scanning (P＜0.05).(7) Logistic regression analysis revealed that the existence of thyroid cancer was significantly associated with age,fasting blood glucose,ultrasonic images(lymph node metastasis,irregular shape,and calcification).Conclusion (1) Fasting blood glucose levels and TSH in the malignant nodules group are higher than those in the benign group.(2) A negative correlation exists between age and thyroid cancer prevalence.(3) Ultrasonic images,including lymph node metastasis,irregular nodule shape,and calcification,may suggest the high possibility of thyroid cancer.

To understand the structure of the soluble region of Enterovirus 68 3A protein, we construct a prokaryotic expression vector expressing the soluble region of EV-D68 3A protein, and identify the forms of expression product after purification. The EV-D68 3A(1-61) gene was amplified by PCR and then cloned into the expression vector pET-28a-His-SUMO. The recombinant plasmid was transformed into Escherichia coli BL21 induced by IPTG to express the fusion protein His-SUMO-3A(1-61). The recombinant protein was purified by Ni-NTA Agarose and cleaved by ULP Protease to remove His-SUMO tag. After that, the target protein 3A(1-61) was purified by a series of purification methods such as Ni-NTA, anion exchange chromatography and gel filtration chromato- graphy. Chemical cross-linking reaction assay was taken to determine the multiple polymerization state of the 3A soluble region. A prokaryotic expression vector pET28a-His-SUMO-3A(1-61) expressing the solution region of EV-D68 3A was successfully constructed and plenty of highly pure target proteins were obtained by multiple purification steps . The total protein amount was about 5 mg obtained from 1L Escherichia coli BL21 with purity > 95%. At the same time, those results determined the homomultimer form of soluble 3A construct. These data demonstrated that the expression and purification system of the soluble region of 3A were successfully set up and provide some basic konwledge for the research about 3A crystal structure and the development of antiviral drugs targeted at 3A to block viral replication.

Hypertension is an important risk factor for cardiovascular and cerebrovascular diseases,which can damage structure and function of vital organs such as the heart,brain and kidney.Pseudo hypertension (PHT) refers to the blood pressure measured by ordinary cuffmanometry is higher than that of the arterial puncture,which is an essential factor of refractory hypertension.Recent findings have suggested that the elderly patients with concomitant history of atherosclerotic disease,renal insufficiency,and diabetes mellitus have the highest risk of pseudohypertension.The incidence rate ofpseudohypertension is about 1.7％-50％ in domestic and international studies.In the clinical treatment,the misdiagnosis of hypertension of patients with excessive blood pressure will lead to severe perfusion defects.In this review,we will focus on the diagnosis and pathogenesis of pseudohypertension.

Objective To evaluate the inlluence of atopy on juvenile idiopathic arthritis (JIA).Methods The study involved 117 cases with JIA from Department of Pediatrics,Renji Hospital Affiliated to School of Medicine of Shanghai Jiaotong University from Jul.2008 to Jul.2013.These patients were enrolled for retrospective cohort study,and subdivided into JIA and atopic group or JIA and non-atopic group.There were 34 cases combined with atopy,83 cases without atopy.Based on the diagnosis of allergic rhinitis (AR),those JIA children in the atopic group were organized into AR group (19 cases) and non-AR group (15 cases).The clinical and laboratory data were recorded and analyzed to compare the differences of the remission of American College of Rheumatology Pediatric (ACR Pedi) 30/50/70 between atopic group and non-atopic group,AR group and non-AR group.In AR group,the correlation between AR scores and disease activity score (DAS28) was analyzed.Results 1.The physician's and patients'/parents' general assessment on a 100 mm visual-analogue scale (VAS),number of joints with restriction of movement and childhood health assessment questionnaire (CHAQ) were significantly elevated in atopic group compared with controls at the beginning (all P ＜ 0.05).In the follow-up 3 months after disease onset,the proportion of reaching ACR Pedi 30,50 and the proportion of reaching ACR Pedi 50,70 in 6 months later in JIA with atopy were lower than JIA children without atopy (all P ＜ 0.05) ; In the follow-up 3 and 6 months,the cumulative glucocorticoid dose was higher in atopy group compared with Non-atopy,which showed a statistical significance (all P ＜ 0.05).2.Among the AR group,at the disease onset,the physician's and patients'/parents' VAS,number of joints with restriction of movement and CHAQ were elevated in AR group compared with controls with statistical significance (all P ＜ 0.05).In the follow-up 3 months,the proportion of reaching ACR Pedi 30 and 50 was lower in AR group compared with non-AR group.In the follow-up 6 months,the cumulative glucocorticoid dose was higher in AR group compared with non-AR,which showed a statistical significance.But the ratio of ACR Pedi 30,50 and 70 were lower in AR group compared with non-AR group (all P ＜ 0.05).Among JIA combined with AR,at the beginning,follow-up 3 and 6 months after disease onset,the scores of AR positively correlated with DAS28 (r =0.671,0.518,0.496,all P ＜ 0.05).Conclusion Atopy or AR may exert an adverse influence on JIA.

Objective To investigate the expressions of cancerous inhibitor of protein phosphatase 2A (CIP2A) and vascular endothelial growth factor (VEGF) in hepatocellular carcinomas and their clinical significance.Methods The expressions of CIP2A and VEGF proteins were tested with immunohistochemistry in 60 cases of hepatocellular carcinomas and adjacent paracancerous tissues.Results The positive rate of CIP2A in hepatocellular carcinomas was significantly higher than adjacent paracancerous tissues (83.3％ vs 9.5％,P ＜ 0.05).Significant differences were also observed in the expression rate of VEGF between the patients with hepatocellular carcinomas and paracancerous tissues (75.0％ vs 14.3％,P ＜0.05).The expression of CIP2A in hepatocellular carcinomas was significantly positively correlated with its pathological grading,differentiation,and tumor node metastasis (TNM) stage (P ＜ 0.05).The expression of VEGF in hepatocellular carcinomas was significantly positively correlated with its pathological grading,differentiation,and TNM stage (P ＜ 0.05).Significantly positive correlation was found between expressions of CIP2A and VEGF with Spearman correlation analysis (rs =0.465,P ＜ 0.01).Conclusions The abnormal expressions of CIP2A and VEGF gene may promote tumor angiogenesis and progression of a hepatocellular carcinoma.The study supports positive regulation between expressions of CIP2A and VEGF in a hepatocellular carcinoma.

A three-phase depletion/repletion/depletion feeding study was designed to investigate the changes of Se levels and glutathione peroxidase (GSH-Px) activities in tissues and blood in rats fed for 6 weeks low-Se diet (6 ppb Se) from a Keshan disease area during the supplementations of Se as Ziyang high-Se wheat (1.175 ppm Se) or sodium selenite (dietary Se 219 and 223 ppb respectively) and after the supplements were discontinued, and to evaluate the relative bioavailability of Se in the wheat. The resalts showed that the average bioavailability of Se in high-Se wheat derived from the values at wk 2, 4 and 6 of supplement was close to that in selenite when plasma, erythrocyte, kidney, liver and cardiac Se contents were used as the response criteria, the relative bioavailabilities being 98%, 104%,100%,96% and 101% (sodium selenite = 100%) respectively. The bioavailability was lower for Se in high-Se wheat (70% or 90%) than for selenite when estimated by erythro-cyte or cardiac GSH-Px activities. However, the bioavailabilities of high-Se wheat Se in various tissues were not all the same at different stages of supplement. In addition, the effect of Se in high-Se wheat in maintaining either Se levels in heart, liver and erythrocyte or GSH-Px activity in heart was superior to that of selenite 3 weeks after the Se supplements were withdrawn.

The intra-tumor MTX concentration was measured in 12 patients with cerebral gliomas and 31 patients of malignant gliomas were treated with intracarotid infusion of papaverine and bis-chloroaitrosourea (BCNU). After intracarotid infusion of papaverine to open up the blood-brain-barrier (BBB), the MTX concentration within tumor tissues was 1854? 512ng/gram, which higher than that without papaverine infusion, which was 1020? 512ng/gram. The diagnosis was glioblastoma in 21 patients and anaplastic astrocytoma in 10. They received the infusion for a mean of 2.1 times with 250mg BCNU each. The mean survival time was 101.6? 32.7 weeks, with 104 weeks of median survival time. Fourteen were still living, including 11 glioblastoma and 3 anaplastic astrocytoma. Of those, four have lived over three years. We considered combination of papaverine and BCNU infusion for chemotherapy of malignant cerebral glioma is simple, safe and effective, so long as tumors were susceptible to the chemotherapeutic drugs.
