Copeptin,the C-terminal portion of provasopressin,is a novel neurohormone of the arginine vasopressin (AVP)system,and is known to be co-released with AVP from hypothalamus.As a surrogate marker of the AVP system,copeptin has gradually replaced AVP in several clinical studies largely due to its structural and methodological advantages.Copeptin has been regarded as a marker of non-specific stress response.In recent years,copeptin attracts more and more attention especially in cardiovascular conditions (heart failure and acute coronary syndromes).The present review primarily focuses on copeptin detection,its general advantages,and its potential clinical value in a variety of cardiovascular conditions.

Objective To understand the e ffect of physical and intellectual development of children with intrauterine inf ection of Toxoplasma gondii. M ethods With matching method, 167 children born betw een 1990 and 1996 were selected, whose umbilical cord blood with antibodies of [WT5”BX ]Toxoplasma gondii as positive group, while 160 childr en whose umbilical cord blood without antibodies of Toxopla sma gondii were selected as the contrast. Their physical index a nd IQ were examined with routine method and Binei or WISP. The measurement numbe rs of nine cities of China were as the standard. The relationship between infect ion of Toxoplasma gondii and the intellectual a nd physical development was analyzed. Results I ntellectual development of children with intrauterine infection of [WT5” BX]Toxoplasma gondii[WT5”B Z] was obviously slow and their eyesights were poor. However, the infection of [ WT5”BX]Toxoplasma gondii had no effect on their height an d weight. Conclusion The children with intrauter ine infection of Toxoplasma gondii should be sy stematically treated after birth so as to lower the harm to the brains and eyes, raise their intellectual levels and improve their healthy development.

Objective To evaluate short-term efficacy, predictability, and rotational stability of the Acrysof SN60TT toric intraocular lens (IOL). Design Prospective case series. Participants 25 senile or evolutionary cataract patients (30 eyes) with more than 1.0 diopter (D) of preexisting corneal astigmatism. Methods The type and aim-axis of IOL was calculated using calculator software (date from biometry). The site of incision and aim-axis of IOL was marked before operation. Phacoemulsification was performed, and an Acrysof SN60TT toric IOL was implanted and rotated into the astigmatic axis. All patients were followed up for 3 months. Main Outcome Measures Uncorrected visual acuity (UCVA), best corrected visual acuity(BCVA),refraction, corneal astigmatism, and cylind er axis of the toric IOL. Results After the implantation of the Acrysof SA60TT toric intraocular lens, the UCVAs were 0.73?0.18 (1 month), 0.79?0.17 (3 months). The BCVAs were 0.93?0.13 (1 month), 0.98?0.09 (3 months). The refractive astigmatisms were 0.68?0.53 D (1 month), 0.47?0.39 D (3 months). The surgically induced astigmatism was 0.62?0.32 D. Astigmatism reduced from IOL was 1.27?0.69 D, compared to predicted 1.36?0.44 D (P=0.31). The axis alignment error was 4.0?3.2 degrees. At the final visit, 76.7% of the IOLs were within 5 degrees of the intended axis. Conclusion Implantation of Acrysof SA60TT toric IOL for correction of astigmatism in short-term is effective and stable. This IOL is showed no significant rotation postoperatively with rotational stability in the capsular bag.

Objective To study the clearance of high risk human papillomavirus(HPV)infection among the women with normal cervical pathologic diagnosis.Methods One hundred and seventy.two HPV-positive cases with normal cervical pathologic diagnosis were enrolled in the study.The infection status of HPV was monitored during follow-up from Aug 2006 to Aug 2008.The time of HPV infection spontaneous clearance,as well as effect factors,were analyzed.Results During follow-up,there were 62.2%(107 cases,107/172) of the HPV infection cleared.The medium clearance time was 11.3 months(95% CI:10.6-16.6 months).The medium clearance time of aged<30 years,30-39 years,40-49 years and>49 years were 11.3,12.0,10.9 and 8.5 months.respectively.There were not significant difference among aged intervals (P=0.384).The virus copies of HPV-clearance cases and persistent-infection were 22.6 and 95.0,respectively.There was not significant difference between groups(P=0.061).Conclusions Most of the high risk HPV infection with normal cervical pathologic diagnosis would spontaneously cleared.Age and HPV copies may play little role in the HPV clearance.

Objective To investigate the expression of β-catenin and Oct-4 in colonal carcinoma and explore the relationship with recurrence and metastasis after operation. MethodsImmunohistochemical analysis was used to evaluate the expression of β-catenin and Oct-4.The correlation of β-catenin and Oct-4 expression with tumor cell differentiation,T stage,N stage and metastasis was analyzed.The gene expression of Oct-4 was examined by RT-PCR in 20 frozen tumor tissues and normal tissues adjacent to tumor.Results Thirty-five patients had metastasis. The positive rates of β-catenin and Oct-4 expression were significantly higher in metastasis group than in the non-metastasis group (65.71% vs 31.11%,51.43 %vs 13.33 %,x2 =9.843,P =0.002,x2 =13.605,P =0.001).Expression of β-catenin and Oct-4 was not associated with differentiation,T stage or N stage.The positive expression rate of Oct-4 in colonal carcinoma tissues was significantly higher than that in normal tissues.Metastatic rates in patients with positive expression of β-catenin and Oct-4 was higher than that in negative expression.The survival analysis showed that time of metastasis was significantly different in two groups of patients (P <0.05).Conclusion The expression of β-catenin and Oct-4 in tumor tissues is related to metastasis of colonal cancer after surgery and might be used to predict metastasis of colonal cancer after operation.

To optimize the formula of levodopa microcapsules floating tablets. Methods:The contents of levodopa and benserazide in the microcapsules floating tablets were determined by HPLC simultaneously. The release rate as the index, an orthogonal design was used to optimize the formula and preparation technology of levodopa microcapsules floating tablets. The release property of the microcapsules floating tablets was evaluated. Results:The HPLC method for the in vitro determination of levodopa and benserazide in the floating tablets met the methodological requirements. The selected formula was as following:the amount ratio of stearic acid, the drugs, acrylic resin and HPMC was 2∶5∶2∶1. The average weight of the tablets was 550 mg. The results of validated tests showed that the microcapsules floating tablets had floating and sustained release property, which could be used by divided dose. Conclusion: The optimized formula of the microcapsules floating tablets is reasonable, and the production process is stable and feasible.

Objective To observe the application of allopurinol in the treatment of gouty nephropathy, and evaluate its clinical effect on the level of serum creatinine and urea nitrogen. Methods Patients with gouty nephropathy from April 2015 to May 2017 in Xining first people's hospital 126 patients as the research object, divided into observation group and control group of 63 cases with double blind random method, given the reference group of patients basic treatment, the observation group treated with allopurinol in the reference group on the basis, effects were compared between the two groups the clinical therapeutic effect and serum creatinine and blood urea nitrogen, blood pressure level. Results After 12 months of therapy, compared two groups of patients before treatment, serum uric acid, creatinine, blood urea nitrogen, blood pressure (systolic blood pressure, diastolic blood pressure) were improved, and the observation group was obviously better than that of control group (P<0.05); the observation group total efficiency of treatment group was 88.89% (56/63), the reference group was 74.60% (47/63), with significant difference between two groups (P<0.05). Conclusion Allopurinol can be used in the treatment of gouty nephropathy. It can help to improve the clinical effect and improve the clinical symptoms of the patients. It is of practical value.
