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 discuss the value of amnionic fluid lamellar body count(LBC) as a predictor of fetal lung maturity. Methods Amnionic fluid was obtained during the cesarean section of 41 normal term pregnancies. LBC was performed on each specimen, and lecithin-sphingomyelin(L/S) ratio was detected simultaneously. Results (1)Amnionic fluid LBC was (86?43)?10 3 (72.5?10 3~99.4?10 3) in normal term pregnancy. (2) Positive correlation was shown between the amnionic fluid LBC and L/S ratio(r=0.66,P=0.001). Conclusion The LBC is a rapid and accurate method to determine the fetal lung maturity.
5.A large-stale aero transportation of mass casualties away from 5.12 Wenchuan earthquake region to other provinces
Chinese Journal of Emergency Medicine 2008;17(8):794-796
Objective To sum up the experience of a large-scale aero transportation of mass casualties away from the quake-hit region to distant cities,and to provide reference for medical transportation of mass casualties.Method The study analyzed the aero medical transportation of 3 482 casualties from quake-hit region treated in West China Hospital of Siehuan University and other seven hospitals in Sichuan Province to other provinces from 22 May 2008 to 3 June 2008.The influencing factors of aero medical transportation were discussed,including selection standard of patients,preparation of staff and mcterials before transportation,management during transportation.The selection standards were:patients with stable condition after orthopedic operation and craniocerebral operation,and patients with passage of gas by anus after abdominal operation 5 days.Results Total of 3 482 casualties were transported in 99 times to 19 cities including Guangzhou,Shanghai,Shenyang,only 8 victims felt a little bit uncomfortable during flight,and recovered soon after management.Conclusions Total of 3 482 patients were safely transported.Strict selection of patients,comprehensive planning and monitoring,and psychotherapy are important for aero medical transfer.

Objective To explore the characteristics and its influential factors of bone mineral density (BMD) changes in partial androgen deficiency in aging male patients.Methods 186 aging male patients with partial androgen deficiency and 125 healthy persons were selected, and their BMD in the first to fourth lumber spine and the proximal left femur was measured with the dual-energy X BMD measuring instrument.The biochemical and bone metabolic markers and sexual hormones were collected, and the relationship between changes of BMD in the patients with partial androgen deficiency, age, BMI, sexual hormones and bone metabolic markers were observed by multivariate stepwise regression analysis.Results There was no significant difference in BMD at the lumbar spine between two groups( P > 0.05 ), but BMD in PADAM group was lower than control groups at the hip[Neck: (0.831 ±0.136) g/cm2 vs (0.954 ±0.143) g/cm2,War's: (0.712 ± 0.127 ) g/cm2 vs ( 0.811 ± 0.149 ) g/cm2,Troch: ( 0.697 ± 0.124 ) g/cm2 vs ( 0.764 ±0.131 )g/cm2, P < 0.05 )].The incidence of PADAM and control group with osteopenia were 48.9% and 36%, and the osteoporosis was 33.3% and 20.8%, respectively.The bone mineral density was positively correlated to BMI at the first to fourth lumber spine and the proximal left femur in the patients with PADAM and negatively correlated to age and serum level of androgen.Conclusion BMD in PADAM group was significantly decreased, and age and low BMI and androgen deficiency wwere the risk factors of low BMD in PADAM patients.

OBJECTIVETo investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).
METHODSEighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group. Points such as Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zhangmen (LR 13), Jingmen (GB 25), Qimen (LR 14), Ganshu (BL 18), Weishu (BL 21), Pishu (BL 20), Shenshu (BL 23), Dachangshu (BL 25) and Xiaochangshu (BL 27), etc. were adopted for embedding therapy. At the same time, needle-pricking therapy on Sifeng (EX-UE 10) was also applied once a week. 0. 5 g metformin hydrochloride tablet was given to the control group, once a day for the first week, and twice a day from the second week. Estimation on therapeutic effect was made for both groups after 3 months treatment. Change of symptoms and signs scores, fasting insulin (FINS), 2 hour insulin after meal (2hINS) and insulin resistance index (HOMA-IR) of both groups before and after treatment were observed, and therapeutic effect estimated.
RESULTSThe total effective rate of the observation group is 97. 6% (41/42), and that of the control group was 95. 4% (41/43). There was no significant difference between the two groups (P>0. 05). Scores of symptoms and signs after treatment were significantly improved in both groups (all P<0. 01), and the observation group was better than the control group (7.01+/-4.23 vs 8. 47+/-2. 82,P<0. 05). Compare with those before the treatment, FINS, 2hINS and HOMA-IR after the treatment were all decreased in both groups (all P<0. 05). The comparison between the two groups showed that differences of FIN had no statistic significance (P>0. 05) after the treatment, while both differences of 2hINS and HOMA-IR had statistic significance [ 2hlNS: (443. 531+/- 93. 90) pmol/L vs (621.29+/-93. 87) pmol/L ; HOMA-IR: 4. 88+/-0. 30 vs 5.06+/-0. 32, both P<0. 05]. The improvement of 2hINS and HOMA-IR in the observation group was better than that of the control group.
CONCLUSIONTreatment of PCOS of damp-phlegm constitution with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) have positive effect, which can effectively reduce the insulin resistance, meanwhile, reduce the side-effects of western medication.

Objective To study the countermeasures for preventing medical disputes-induced group events by ana-lyzing the related papers.Methods Distributions of publication years, institutions of authors, and subjects in pa-pers on medical disputes-induced group events in 2006-2013 covered in Wanfang Data Knowledge Service Platform and CNKI were analyzed by bibliometrics.Results A total of 676 papers on medical disputes-induced group events were published in 2006-2013 .Their authors were mainly from medical educational institutions or medical and health institutions.The number of papers on medical tangles, relation between physicians and patients, legal con-struction, reasons for medical disputes was significantly larger than that of those on the third partymechanism and medical liability insurance .Conclusion Certain advances have been achieved in study on medical disputes-induced group events.However, there is a room for their improvement, further studies are thus needed.
