Purpose To study the cytopathologic features of CT-guided percutaneous lung biopsy samples and to evaluate the role of cytopathology in the diagnosis and staging of lung carcinomas, as compared to histopathology. Methods Four-hundred twenty-five specimens were collected by CT-guided percutaneous lung biopsy which were also confirmed by histological diagnosis. Direct smears were performed for each case. Cytological and histological examination was carried out. Results The sensitivity, specificity, false positive rate, false negative rate and accuracy of cytopathology in diagnosing lung carcinomas by CT-guided percutaneous lung biopsy was 86. 6% (264/305), 100% (120/120), 0 (0/120), 13. 4% (41/305), 90. 4% (384/425), respectively. Overall 51. 1%(135/264) of the cases were precisely typed, including 77. 6% (83/107) of adenocarcinoma, 76. 9% (40/52) of squamous cell car-cinoma and 75. 0% (9/12) of small cell carcinoma. Conclusions Cytopathology of CT-guided percutaneous lung biopsy specimens is sensitive and accurate for diagnosing pulmonary carcinomas. In some cases, the lung carcinoma can be precisely typed. Therefore, it is useful for diagnosing and staging lung carcinomas.

Objective To evaluate the significance of standardized ultrasound examination of fetal structures in the ifrst trimester (11-13+6 weeks). Methods The ultrasound data of 29 858 fetuses who underwent the ifrst trimester screening were analyzed retrospectively in Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2010 to December 2012 and followed up the cases with structural abnormalities and increased nuchal translucency (NT). Results Among 29 858 fetuses, 328 structural defects were detected in 284 fetuses (0.95%) by ultrasound in the first trimester, including fetal hydrops (124 cases), choroid plexus cysts (36 cases), exencephaly (32 cases), gastroschisis (24 cases), exomphalos (22 cases), cardiac defects (19 cases), megacystis (14 cases), spine abnormalities (10 cases), meningoceles/encephaloceles (9 cases), alobar holoprosencephaly (8 cases), hydrocephaly (7 cases), abnormalities of extremities (7 cases), acrania (6 cases), amniotic band syndrome (4 cases), abdominal cyst (3 cases) and conjoined twins (3 cases). Pregnancy was terminated in all cases (115) with exencephaly, gastroschisis, exomphalos, meningoceles/encephaloceles, alobar holoprosencephaly, hydrocephaly,abnormalities of extremities, acrania, amniotic band syndrome and conjoined twins, and the defects were verified by the gross appearance of fetuses. Two cases of megacystis were turned out to be normal during follow-up while 1 case was proved to be aneuploid and 1 other case progressed to multiple abnormalities during the second trimester. Most choroid plexus cysts, except 1 case of aneuploid, were normal during the second and the third trimester follow-ups by ultrasound. Thirteen cases of fetal hydrops were found to be aneuploids and 4 hydrops cases were proved to be complicated with other structural defects during the second and the third trimester. NT was increased in 422 cases (1.41%), among which 122 cases (28.91%) were complicated with structural defects and/or fetal hydrops. Ninty-nine cases with increased NT underwent chromosomal examination and 38 cases were found to be aneuploides. During the follow-up of 298 cases with increased NT who continued pregnancy, 21 structural abnormalities were found, including cardiac defects (14 cases), neural abnormalities (4 cases) and diaphragmatic hernia (3 cases). Conclusion The standardized fetal ultrasound in the first trimester is a effective tool for the screening of aneupolides and major structural abnormalities.

Depression is a common emotional disorder that seriously affects people's life and health all over the world. The pathogenesis of depression is complex, and traditional Chinese medicine (TCM) for antidepressants has a good therapeutic effect because of its multi-component, multi-pathway, and multi-target action mode. At present, the anti-depressive mechanism of TCM has not been fully clarified, but it is clear that depression is closely related to metabolic health. Therefore, in order to further explore the anti-depressive mechanism of TCM, this paper proposes research strategies on the anti-depressive mechanism of TCM based on functional metabolomics from the perspective of metabolism, the potential biomarkers of depression are analyzed with the help of multi-omics combined analysis technology, and the functional molecules of TCM for antidepressant are studied. Molecular biology techniques are used to accurately capture the molecular interactions between biomarkers of depression and functional compounds, which identify effective drug targets and further elucidate the biochemical functions and related mechanisms involved in depression metabolic disorders. This paper systematically reviews the research strategies and applications of functional metabolomics in the anti-depressive mechanisms of TCM, expounds on the core value of functional metabolomics, and summarizes the current research status and hot issues of TCM for antidepressants in recent years, providing new methods and new ideas for the study of mechanisms of TCM with the help of functional metabolomics.

OBJECTIVETo evaluate incidence of postoperative delirium after hip surgery in elderly patients by meta-analysis.
METHODSFrom January 1, 2014 to December 31, 2013, clinical literatures about postoperative delirium after hip surgery in elderly patients,were searched from the Pubmed. Literature extract table were formed according to inclusion and exclusion criteria. Stata-12.0 was applied for Meta-analysis. P was used to test heterogeneity of study, random-effect model was performed when I2 > 50%. Subgroup analysis was used according to stage of age, assessment scale of delirium and statistical area of literature. Begg test was used to test publication bias.
RESULTSTwenty-one literatures were included. Incidence of postoperative delirium after hip surgery in elderly patients by weighted and combination was 17% [95% CI (16%, 18%)]. Incidence of postoperative delirium after optional hip surgery was decreased more than emergency operation in included 5 literatures [OR = 0.32, 95% CI (0.22, 0.45)]. Incidence of postoperative delirium in patients less than 80 years old was 21% [95% CI (19%, 23%)], while 21% [95% CI (19%, 24%)] in patients more than 80 years old. Incidence of postoperative delirium in CAM evaluation scale was 23% [95% CI (21%, 26%)], while 19% [95% CI (17%, 21%)] in other evaluation scales. Incidence of postoperative delirium in Asian area was 17% [95% CI (15%, 20%)], while 23% [95% CI (21%, 25%)] in European and American area. There was no publication bias tested by Begg test (P < 0.05).
CONCLUSIONIncidence of postoperative delirium after hip surgery in elderly patients increases higher, especially in emergency operation. A standardizing research method is benefit for evaluate incidence of postoperative delirium after hip surgery in elderly patients, decreasing heterogeneity and publication bias.

AIM: To study the relation of acute radiation-induced oral mucositis to fungal infection and evaluate the effect of fluconazole in the treatment of patients with fungal infection. METHODS: Seventy-one patients (M 42, F 29; 52 a± s 41 a,11-76 a) with large area of oral mucosas irradiated were into this study. When most serious mucositis, the patients' oral mucosas were checked, 32 patients with fungal infection were treated with fluconazole (fluconazole 100 mg, po, qd×5 d or 150 mg,iv,gtt×3 d). RESULTS: The rate of fungal infection was 45%, the most of patients were infected by candida albicans. Degrees of mucositis between the patients with fungal infection to the patients without fungal infection were significantly different (P<0.05). The patients with fungal infection were treated with fluconazole. Degree of mucositis between the pretreated patients and post-treated patients were significantly different (P<0.05). CONCLUSION: The serious acute radiation-induced oral mucositis has significantly related with fungal infection. The patients with fungus infection treated with antifungal agents (fluconazole) can significantly relieve the reaction of acute radiation-induced oral mucositis.
