Results Successful puncturing of thyroid node was accomplished in all 65 patients. One patient developed subcutaneous hematoma. The coincidence rate between puncture biopsy results and postoperative pathologic findings was 93.8%(61/65). Five of 6 cases with thyroid cancer agreed with the pathologic diagnosis. Conclusion For the diagnosis of thyroid diseases, CT-guided percutaneous puncture biopsy is simple, safe and reliable, with higher success rate.

We reported a case of monochorionic monoamniotic twins discordant for anencephaly diagnosed by second-trimester ultrasonography at the First Affiliated Hospital of Fujian Medical University.Ultrasound at seven weeks of gestation showed only one gestational sac with an embryo inside.Another 12 gestational weeks' ultrasound scan performed at another hospital found one gestational sac and one fetus (crown-rump length was 6.11 cm and nuchal translucency was 0.11 cm) in the upper-middle uterine cavity.The ultrasound examination at 22+6 gestational weeks identified one placenta and two fetuses without obvious diaphragm echo in between.Although no structural abnormality was observed in one fetus,frog-like eyes,absence of skull image and brain tissue echo were presented in the other fetus.The patient was transferred to a higher level hospital and was successfully performed radiofrequency ablation for selective reduction at 23+4 weeks of gestation.At 35 weeks,a premature live boy and an anencephalic stillbirth fetus were born vaginally after premature rupture of membranes.The baby boy was healthy at follow-up at four months old.

Astragali Radix(AR)is a clinically used herbal medicine with multiple immunomodulatory activities that can strengthen the activity and cytotoxicity of natural killer(NK)cells.However,owing to the complexity of its composition,the specific active ingredients in AR that act on NK cells are not clear yet.Cell membrane chromatography(CMC)is mainly used to screen the active ingredients in a complex system of herbal medicines.In this study,a new comprehensive two-dimensional(2D)NK-92MI CMC/C18 column/time-of-flight mass spectrometry(TOFMS)system was established to screen for potential NK cell acti-vators.To obtain a higher column efficiency,3-mercaptopropyltrimethoxysilane-modified silica was synthesized to prepare the NK-92MI CMC column.In total,nine components in AR were screened from this system,which could be washed out from the NK-92MI/CMC column after 10 min,and they showed good affinity for NK-92MI/CMC column.Two representative active compounds of AR,isoastragaloside Ⅰ and astragaloside Ⅳ,promoted the killing effect of NK cells on K562 cells in a dose-dependent manner.It can thus suggest that isoastragaloside Ⅰ and astragaloside Ⅳ are the main immunomodulatory compo-nents of AR.This comprehensive 2D NK-92MI CMC analytical system is a practical method for screening immune cell activators from other herbal medicines with immunomodulatory effects.

Objective This paper investigated the clinical application of CRT+ARC technique in locally advanced lung cancer. Methods A total of 100 patients with locally advanced lung cancer who underwent radiotherapy in our hospital from March 1,2016 to March 1,2017 were randomly assigned to the experimental and control groups. Each group consisted of 50 patients. The CRT+ARC plans were made for the experimental group,and the CRT + intensity-modulated radiotherapy(IMRT)(CRT+IMRT) plans for the control group. According to the World Health Organization( WHO) criteria,the short-term efficacy of patients was as-sessed. According to the imaging examination and the Radiation Therapy Organization Group(RTOG)standard,the occurrence of major side effects of radiation pneumonia was identified. Results The effective rate of treatment was 82% in the experimental group and 76% in the control group. There was no difference in the effective rate between the two groups(χ2 =0. 542,P=0. 461). The incidence of pneumonia in the experimental group was 22% ,and 18% in the control group. There was also no difference in the incidence of pneumonia between the two groups(χ2 =0. 250,P=0. 617). Conclusion In the clinical application of locally advanced lung cancer, CRT+ARC technique has no difference in the short-term efficacy and the main side effects of radiation pneumonitis compared with CRT+IMRT.

Background: Fatty acid-binding protein 4 (FABP4) has been demonstrated to be a predictor of early diabetic nephropathy. However, little is known about the relationship between FABP4 and diabetic retinopathy (DR). This study explored the value of FABP4 as a biomarker of DR in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 238 subjects were enrolled, including 20 healthy controls and 218 T2DM patients. Serum FABP4 levels were measured using a sandwich enzyme-linked immunosorbent assay. The grade of DR was determined using fundus fluorescence angiography. Based on the international classification of DR, all T2DM patients were classified into the following three subgroups: non-DR group, non-proliferative diabetic retinopathy (NPDR) group, and proliferative diabetic retinopathy (PDR) group. Multivariate logistic regression analyses were employed to assess the correlation between FABP4 levels and DR severity. Results: FABP4 correlated positively with DR severity (r=0.225, P=0.001). Receiver operating characteristic curve analysis was used to assess the diagnostic potential of FABP4 in identifying DR, with an area under the curve of 0.624 (37% sensitivity, 83.6% specificity) and an optimum cut-off value of 76.4 μg/L. Multivariate logistic regression model including FABP4 as a categorized binary variable using the cut-off value of 76.4 μg/L showed that the concentration of FABP4 above the cut-off value increased the risk of NPDR (odds ratio [OR], 3.231; 95% confidence interval [CI], 1.574 to 6.632; P=0.001) and PDR (OR, 3.689; 95% CI, 1.306 to 10.424; P=0.014). Conclusion FABP4 may be used as a serum biomarker for the diagnosis of DR.

Insomnia is a common sleep disorder without effective therapy and can affect a person's life. The mechanism of the disease is not completely understood. Hence, there is a need to understand the targets related to insomnia, in order to develop innovative therapies and new compounds. Recently, increasing interest has been focused on complementary and alternative medicines for treating or preventing insomnia. Research into their molecular components has revealed that their sedative and sleep-promoting properties rely on the interactions with various neurotransmitter systems in the brain. In this review, the role of 5-hydroxytryptamine (5-HT) in insomnia development is summarized, while a systematic analysis of studies is conducted to assess the mechanisms of herbal medicines on different 5-HT receptors subtypes, in order to provide reference for subsequent research.
