BACKGROUND: Paraquat (PQ) is a world-wide used herbicide and also a type of common poison for suicide and accidental poisoning. Numerous studies have proved that the concentration of serum PQ plays an important role in prognosis. Spectrophotometry, including common spectrophotometry and second-derivative spectrophotometry, is commonly used for PQ detection in primary hospitals. So far, lack of systematic research on the reliability of the method and the correlation between clinical features of patients with PQ poisoning and the test results has restricted the clinical use of spectrophotometry. This study aimed to evaluate the reliability and value of spectrophotometry in detecting the concentration of serum PQ. METHODS: The wavelengths for detecting the concentration of serum PQ by common and second-derivative spectrophotometry were determined. Second-derivative spectrophotometry was applied to detect the concentration of serum PQ. The linear range and precision for detection of PQ concentration by this method were confirmed. The concentration of serum PQ shown by second-derivative spectrophotometry and HPLC were compared in 8 patients with PQ poisoning. Altogether 21 patients with acute poisoning 4 hours after PQ ingestion treated in the period of October 2008 to September 2010 were retrospectively reviewed. The patients were divided into higher and lower than 1.8 μg/mL groups based on their concentrations of serum PQ measured by second-derivative spectrophotometry on admission. The severity of clinical manifestations between the two groups were analyzed with Student's t test or Fisher's exact test. RESULTS: The absorption peak of 257 nm could not be found when common spectrophotometry was used to detect the PQ concentration in serum. The calibration curve in the 0.4–8.0 μg/mL range for PQ concentration shown by second-derivative spectrophotometry obeyed Beer's law with r=0.996. The average recovery rates of PQ were within a range of 95.0% to 99.5%, relative standard deviation (RSD) was within 1.35% to 5.41% (n=6), and the lower detection limit was 0.05 μg/mL. The PQ concentrations in serum of 8 patients with PQ poisoning shown by second-derivative spectrophotometry were consistent with the quantitative determinations by HPLC (r=0.995, P<0.0001). The survival rate was 22.2% in patients whose PQ concentration in serum was more than 1.8 μg/mL, and the incidences of acidosis, oliguria and pneumomediastinum in these patients were 55.6%, 55.6%and 77.8%, respectively. These clinical manifestations were different significantly from those of the patients whose PQ concentration in serum was less than 1.8 μg/mL (P<0.05). CONCLUSIONS: For common spectrophotometry, the wavelength at 257 nm was not suitable for detecting serum PQ as no absorbance was shown. Second-derivative spectrophotometry was reliable for detecting serum paraquat concentration. Serum PQ concentration detected by second-derivative spectrophotometry could be used to predict the severity of clinical manifestations of patients with PQ poisoning, and PQ content higher than 1.8 μg/mL 4 hours after ingestion could be an important predictive factor for poor prognosis.

"Vessels Collateral Theory", as the inherit and development of "blood vessels" in Huangdi Neijing, is a systematic system by integrating severe vascular diseases. In this article, by taking cardiovascular diseases (CVD) as a cut-in point, roles of "minute collateral-microvascular" lesions in the occurrence and development of CVD were further explored. The interventional effect of collateral-unblocking medicines under the guidance of Vessels Collateral Theory was also in-depth explored, hoping to leading Chinese medical prevention and treatment of CVD.

Part of the patients with transient ischemic attack (TIA) may develop ischemic stroke.Some of them may die because of complicating cardiovascular disease.Studies in recent years have shown that the ABCD2 score has an important value in the evaluation of the prognosis of TIA.This article summarizes the source and application of the ABCD2 score,and focuses on the roles of the score in the evaluation of the prognosis of TIA.

To evaluate the clinical effect of laser in situ keratomileusis ( LASlK) with the corneal flap created by FEMTO LDV femtosecond laser for myopia.
●METHODS: The corneal flap was created by the FEMTO LDV femtosecond laser, and the thickness of the flap was 110μ m. A total of 143 myopic patients (283 eyes) were treated with the EC5000 - CXlll element laser. The optometry of the eye, best corrected visual acuity (BCVA) the thickness of the cornea, and ObscanⅡ were examined before the operation. The thickness of the flap was calculated by measuring the thickness of corneal bed during the operation in 35 eyes. The conditions of the corneal flap, complications, uncorrected visual acuity ( UCVA ), diopter, corneal topography were observed during and after the operation and were checked for 3mo follow-up.
●RESULTS: During the operation, it appeared small flap ( diameter < 5mm ) in 3 eyes, corneal margin incised incompletely in 5 eyes and incision bleeding in 8 eyes. Postoperative subconjunctival hemorrhage appeared in 6 eyes. The thickness of corneal flap in 35 eyes was 108. 75± 8. 52μ m (98-117μ m) and the error was 6. 49±8. 62μ m (3-12μ m). There was no significant difference between the actual flap thickness and the preset flap thickness ( P >0. 05) . The average equivalent spherical refractive was -0. 29± 0. 47 ( - 1. 50 to + 1. 00) DS after the operation for 3mo and the UCVA met or exceeded preoperative BCVA in 251 eyes (88. 7%).
●CONCLUSlON: The operation of myopia by LASlK flap created by FEMTO LDV femtosecond laser has fewer complications, and the effect is definite and safe.

Objective To investigate the clinical significance of fetal tricuspid regurgitation (TR) in the screening of chromosomal abnormalities at the first-trimester. Methods Screening for chromosomal abnormalities was carried out in 1 262 fetuses at 11+0 to 13+6 weeks. Ultrosound was performed to measure crown rump length and nuchal translucency (NT) thickness, and to acquire tricuspid waveform. All the neonates were followed up for 6 months after birth. Results Among the 1 262 fetuses, 68 were found to have TR. TR was present in 54 (4.4%) of the 1 239 chromosomally normal fetuses, and in 14 (61%) of the 23 with chromosomal abnormalities. Cardiac malformations were detectable in 28 fetuses. The prevalence of TR was 64%in those with cardiac malformations and 1.5%in those without cardiac malformations. Conclusions Tricuspid regurgitation is an effective predictor for the detection of fetal chromosomal abnormalities at the first trimester.
