Objective To evaluate the significance of fiberoptic bronchoscopic brush cytology in the diagnosis and histological classification of lung carcinoma.Methods Data of 309 patients with lung carcinoma were retrospectively analyzed.Both bronchoscopic cytology and histology diagnosis were available.The positive rate of bronchoscopic cytology and tissue biopsy were calculated respectively.The classification accuracy of cytological diagnosis for lung carcinoma was evaluated.In tissue biopsy standard,evaluated the significance of bronchoscopic cytology in diagnosis and histological diagnosis.Results The positive rate of bronchoscopic cytology and tissue biopsy were 86.1％ (266/309) and 83.8％ (259/309),respectively.Bronchoscopic cytology combined with bronchial biopsy could obviously improve the positive rate to 94.2％ (291/309) in lung carcinoma diagnosis.Taking the tissue biopsy histological type as a standard,the cytotyping accuracy for brush method was 85.1％(74/87) in squamous carcinoma,82.4％(108/131) in adenocarcinoma and 100％(11/11) in small cell carcinoma for higher.However,the accuracy in diagnosing poorly differentiated carcinomas was only 12.2％ (5/ 41).Conclusion Fiberoptic bronchoscopic brush cytology plays an stable and important role in diagnosing lung carcinomas and histological type determination.However,it has limited use in diagnosing poorly differentiated carcinomas.

Objective To study the expression changes and significance of human telomerase reverse transcriptase (hTERT)-mRNA and mutant p53 protein in thyroid carcinoma tissues in the elderly.Methods The expression level of hTERT-mRNA was examined by in situ hybridization in 50 samples of thyroid carcinoma tissues from the elderly and 41 samples of thyroid carcinoma tissues from the non-elderly and 30 samples of thyroid benign lesions.The expression level of p53 was examined by immunohistochemistry in all subjects.Results The positive rate of hTERT-mRNA was 96.0％ (48/50),85.3％ (35/41) and 10.0％ (3/30) in thyroid carcinoma tissues from the elderly,the non-elderly and thyroid benign lesions respectively,and there were significant differences between the three groups (x2=73.61,P=0.000).The positive rate of p53 was 92.0％ (46/50),85.3％ (35/41) and 13.3％ (3/30) in thyroid carcinoma tissues from the elderly,the non-elderly and thyroid benign lesions respectively,and there were significant differences between the three groups (x2 =62.30,P =0.000).Conclusions The positive rates of hTERT-mRNA and p53 in thyroid carcinoma tissues are higher in the elderly than in the non-elderly,which can be used to evaluate the biological behavior and prognosis of thyroid carcinoma in the elderly,and they play the important roles for targeted therapy.

Some issues on the formulation of Standardized manipulations of acupuncture and moxibustion-part 6: acupoint injection are debated in this paper, including the definition of acupoint injection, characteristics of the standard and application of technical index etc. In the paper, the authors suggest that the issues on the selecting acupoints and drugs should be paid attention during the standard in use. Finally, the authors propose that the technical description of the acupoint injection in the reported literatures needs to be improved in order to better serve for clinical and scientific research.

OBJECTIVETo provide basis for strengthening safety of acupoint-injection and increasing clinical therapeutic effect.

METHODSAnalyze and study on the relative articles from the databank of whole articles of Chinese periodicals of CNKI by information retrieval with computer, with acupoint-injection, nerve injury as key words.

RESULTSMost of clinical reports focus on acupoint-injection for treatment of nervous injury induced by trauma and birth injury. The studies indicate that the injuries of the peripheral nerves induced by acupoint-injection can be divided into 3 grades and the injury mechanisms can be divided into 3 classifications. The injuring causes include improper posture of the patients, improper angle and depth of injection and improper medicine selection.

CONCLUSIONAcupoint-injection can be applied more widely as soon as the accomplishment of the standardization of operation.

Objective:To explore the therapeutic effect of psychological and drug intervention on anxiety and depres‐sion in patients after coronary artery bypass graft (CABG) .Methods :A total of 115 patients performed CABG were randomly divided into combined intervention group (n=60) and routine nursing group (n=55) .During peropera‐tive period ,combined intervention group received psychological intervention ,flupentixol and melitracen tablet and sertraline based on routine nursing .A total of 25 matching normal people were selected from community and regar‐ded as normal control group ,scores of Zung self‐rating anxiety scale (SAS) and self‐rating depression scale (SDS) were evaluated and compared among three groups before and after operation .Results :Before intervention ,there were no significant difference in standard scores of SAS and SDS between combined intervention group and routine nursing group ( P > 0.05) ,but they were all significantly higher than those of normal control group , P < 0.01 all . After operation ,standard scores of SAS and SDS in combined intervention group were significantly lower than be ‐ fore operation ( P < 0.01 both) ,and they were significantly lower than those of routine nursing group [SAS : (41.31 ± 6.13) scores vs .(51.35 ± 8.95) scores ,SDS : (40.20 ± 5.80) scores vs .(51.22 ± 8.78) scores , P < 0.01 both] . Conclusion :Psychological combined drug intervention could significantly relieve anxiety and depression in patients after coronary artery bypass graft ,which is helpful for improving postoperative prognosis .

Objective To investigate expression levels of epithelial mucin 1 (MUC1) and epitbelial mucin15(MUC15) in elderly patients with papillary thyroid carcinoma and assess the role of MUC1 and MUC15 in the pathogenesis of thyroid papillary carcinoma.Methods Protein expression of MUC1 and MUC15 was detected by immunohistochemistry in 10 samples from normal thyroid tissue adjacent to thyroid adenoma,57 samples from papillary thyroid carcinoma (PTC),and 14 samples from PTC in neck lymph node metastasis.Results Expression rates of MUC1 in normal thyroid tissues,thyroid papillary carcinoma,and lymph node metastatic carcinoma were 40.0％,75.4％,64.3,respectively,and the rates for MUC15 were 0,73.7％,71.4％,respectively.The positive expression rate of MUC1 was higher in PTC tissues than in normal thyroid tissues (x2 =5.10,P=0.02) and,compared with normal thyroid tissues,the positive expression rate of MUC15 increased in PTC tissues and lymph node metastatic carcinoma (x2 =12.25 and 19.75,both P＜0.05)MUC15 protein expression was higher in micro-PTC (less than or equal to 1 cm in diameter) than in carcinoma larger than 1 cm in diameter (90.9％ vs.62.9,x2 =5.48,P=0.02).MUC15 expression was higher in PTC without lymph node metastasis than in PTC with lymph node metastasis (83.8％vs.55.0％,x2 =5.55,P=0.02).MUC1 expression was positively correlated with MUC15 expression in thyroid papillary carcinoma (r=0.35,P=0.01).Conclusions MUC1 and MUC15 may have synergistic effects in the initiation and progression of PTC.MUC15 may play a role in regulating tumorigenesis of thyroid papillary carcinoma in early stages and can potentially serve as a supplementary marker in the screening of micro-thyroid papillary carcinoma.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

Objective Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia,but active cooling with whole body surface or head cooling is both complex and expensive.The clinical feasibility of passive cooling in treatment of full term infants with severe asphyxia was investigated.Methods Thirty-two severe asphyxiated term newborns treated with hypothermia were analyzed,who were randomly divided into 2 groups:passive cooling group(n =17) and active cooling group(n =15).Active cooling group adopted MTRE ALLONTM-thermo regulatory systems,passive cooling group using natural cooling method.Hypothermia treatment time was 72 hours.At the end of treatment,the clinical manifestations,biochemical parameters and clinical efficacy of infants between the 2 groups were compared.Results During treatment all infants had no cardiac arrhythmia,hypoglycemia,sustained metabolic acidosis,blood-borne infections,local cold injury or bleeding.Infants in passive cooling group had a relatively wide range of rectal temperature fluctuations[average (33.47-0.71) ℃] and infants in active cooling group had a relatively narrow range of rectal temperature fluctuations[average (33.66 ± 0.29) ℃],but there was no statistically significant difference in their mean rectal temperature(t =1.941,P =0.055).One patient died in active cooling group,but there were no significant differences in suckling age,length of hospital stay,neonatal behavioral neurological assessment score,abnormal cranial ultrasound and MRI between the survivors of the two groups(all P ＞0.05).Conclusions In NICU,environmental temperature is relatively stable,passive cooling for asphyxiated newborns appears to be feasible for maintenance of hypothermia with a lower risk of adverse reactions.
