The patients must lie down on the sickbed for a period after percutaneous coronary intervention (PCI). Most patients will feel uncomfortable such as lumbago, backache, abdominal distension, insomnia, dysuria and etc. Therefore measures including adjusting posture, starting exercise as early as possible and preventing bleeding should be taken.

Objective To compare the brainstem auditory evoked potential (BAEP) in patients with different kinds of brainstem disorders, so as to offer a significative electrophysiological means for diagnosis and differential diagnosis of different kinds of brainstem disorders. Methods BAEP was recorded from 80 cases of vertebrobasilar arterial insufficiency, 56 cases of acoustic neuroma and 47 cases of chronic cerebellar degeneration and compared with that from 50 healthy people. Results The abnormal rates of the three different case groups were 73.75%, 94.61%, 89.36%, respectively. Each group of patients demonstrated their own characteristics with regard to the BAEP. Conclusion Each of the three brainstem disorders has its own characteristics with BAEP.

Cholangiocarcinoma (CCA) is a group of solid tumors with high malignant degree and poor prognosis. Surgical resection has still been the main therapy options. Targeting therapy and immunotherapy are the main anti-tumor methods that have been paid more and more attention in recent years, especially immunotherapy. The tumor microenvironment of CCA is complex, which encompasses not only interstitial and endothelial cells, but also a large number of immune cells. In addition, the innate and adaptive immune systems also play a role. This article summarizes the immune-related studies of cholangiocarcinoma and the latest clinical trials of immunotherapy.

Objective To study the relationship between the adult sternum multiple measurements and the body length in Chinese Han population for the purpose of body length estimation. Methods In this article, we had surveyed 135 samples(100 males and 35 females) .The total length of the sternum, the length of the sternal manubrium and the sternal body, the maximum and minimum breadth of the sternal manubrium, the Kleinste Breite des Ma-nubrium sterni, the maximum breadth of the sternal body, the Dicke des Manubrium sterni, the thickness of the sternal manubrium,the maximum thickness of the sternal manubrium and the sternal body in Chinese Han population was measured. Multiple linear regressions for estimating the body length were obtained by the stepwise regressive mathematics. Results Five multiple linear regressions (4 for different male age groups and 1 for female group ) for body length estimation were obtained. The multiple- relationship coefficient(R) was between 0.6237 and 0.7350, and the standard deviation was between 4.5720 and 7.0348. Conclusion The body length could be estimated by the sternum measurement data.However, its accurate was not as well as estimation by the long bone measurement. The male sternum multiple measurement data was significantly different from female. The body length can not be estimated only by the length of the sternal manubrium .

Objective To investigate clinical characteristics of smear- or culture-positive pulmonary tuberculosis (TB) in patients hospitalized at a general hospital to improve its diagnosis. Methods Clinical data of smear- or culture-positive pulmonary TB diagnosed in 50 patients hospitalized at Peking Union Medical College Hospital, Beijing during 2006 to 2009 were analyzed retrospectively. Results Seventeen (34%) of 50 cases of smear- or culture-positive pulmonary TB aged more than 60 years, with 30 males (32%), 16 retirees and nine farmers (18%). Their main symptoms included fever (80%), cough (94%) and sputum expectoration (92%), with elevated erythrocyte sedimentation rate (ESR) in 38 of 45 patients (84%). Chest X-ray examinations showed that lesions located mostly in the upper lobes or in both of the lungs diffusedly, with patchy infiltrations, nodular opacities and cavities. Acid-fast bacilli were demonstrated on sputum smear in 41 ( 82% ) and in specimens of six ( 12% ) cases obtained through bronchoscopy with brush or bronchoalveolar lavage fluid ( BALF), and M. Tuberculosis was cultured from sputum specimens in three (6%). Mean time interval between admission and diagnoses averaged 14 days.Conclusions Basic knowledge about prevention and control of pulmonary tuberculosis should be publicized comprehensively in general hospital keeping alert in its diagnosis with acid-fast staining for sputum smear as a routine test for patients with respiratory symptoms, and in some cases, bronchoscopy procedures ( brush or BALF) are reasonable options to improve its detection.

Objective To analyse the etiology and clinical characteristics of 26 critically ill children with severe hand foot and mouth disease (HFMD) of Shanxi province in 2010.Methods We retrospectively analysed the clinical data of 26 children with severe HFMD from Mar to Sep 2010.Nucleic acid of enterovirus 71 ( EV71 ) and Coxsackie virus A 16 ( CoxA16) were detected in 20 out of 26 children with HFMD by reversed real time polymerase chain reaction (rRT-PCR),and the whole VP1 gene of EV71 deriving from 6 different areas of Shanxi province was amplified,sequenced,and compared with strains from other areas in china.Results EV71 nucleic acid were positive in 18 out of 20 children,while the other two were negative for EV71 and CoxAl6.Among all the critical cases,20 cases (76.9％) occurred in Weinan area,four in Xianyang area,and two in Xi'an urban area.Compared with those of Fuyang Anhui,Hong Kong China,Guangzhou,Shenzhen,Shandong,Beijing,the homology of the whole VP1 gene sequence from 6 strains of Shanxi area was 96％ ～ 100％.Most of the critical children were under 3-year-old,and the incidence rate of male children was higher than that of female children.All affected children had persisted fever,poor energy,hyperarousal,hypersomnia,and limb shaking.Meanwhile their peripheral blood leukocytes,C-reactive protein and blood glucose were markedly increased,but renal injuries were rare.Eighteen children clinically recovered on discharge,among which 2 cases had sequelae of limb activity obstacle,and 8 cases died.Conclusion Weinan is the area with the highest incidence rate of critical HFMD cases in Shanxi Province,and the major etiological organism is EV71,which is highly homologous to EV71 found in other regions of mainland China.As many cases are in dangerous condition,thus early identification and intervention could inhibit the disease progression,and play a key role in reducing the mortality.

Objective To investigate the application value of transvaginal three-dimensional ultrasound combined with tomographic ultrasound imaging (TUI) in the diagnosis of early ectopic pregnancy. Methods One hundred and twenty patients with 4 to 6 weeks menopause were collected. All of the cases were clinical suspected of ectopic pregnancy and the surgical pathology and clinical follow-up results of each case were obtained. Both transvaginal two dimensional ultrasound imaging and three-dimensional ultrasound imaging combined with TUI technique were applied in order to make a diagnosis based on ultrasonographic characteristics for each of the case;surgical pathology and clinical follow-up results were compared with the ultrasonographic diagnosis so as to analysis and conclude the ultrasonographic imaging characteristics of cases misdiagnosed or missed diagnosed by transvaginal two-dimensional ultrasound imaging and three-dimensional ultrasound imaging joint TUI technique. Results One hundred and two cases were confirmed as ectopic pregnancy by surgical pathology and clinical follow-up results among 120 patients and eighteenth cases were confirmed as intrauterine pregnancy. Comparing surgical pathology and clinical follow-up results with the ultrasonographic diagnosis showed:(1) Ninety-two cases of tubal pregnancy:80 cases were correctly diagnosed by transvaginal two-dimensional ultrasound imaging (86.9%, 80/92) while 84 cases by three-dimensional combined with TUI technique (91.3%, 84/92); 8 cases were missed diagnosed by both two methods;4 cases were misdiagnosed by transvaginal two-dimensional ultrasound imaging while zero case by three-dimensional combined with TUI technique. Ultrasonographic imaging characteristics:adnexal masses presented as“Donut”sign which was similar to gestational-sac or masses with irregular boundary. The majority of the masses presented as clear boundaries and internal structure and had obvious margins with fallopian tube. A total 36 cases of unruptured tubal pregnancy were correctly diagnosed by the two methods while 43 cases of abortion type and 5 cases of ruptured type were correctly diagnosed. (2) Ten cases of uterine cornual pregnancy:6 cases were correctly diagnosed by transvaginal two-dimensional ultrasound imaging (60.0%, 6/10) while 9 cases by three-dimensional ultrasound imaging joint TUI technique (90.0%, 9/10);4 cases were misdiagnosd by transvaginal two-dimensional ultrasound imaging and 1 case by three-dimensional ultrasound imaging joint TUI technique. Ultrasonographic imaging characteristics:the gestational-sac was located in the uterine horn, 6 cases of gestational-sac was not connected with endometrium showed by transvaginal two-dimensional ultrasound imaging while 9 cases were clearly showed by three-dimensional ultrasound imaging joint TUI technique that the gestational-sac was connected with endometrium, especially in the coronal-section. The surrounding decidua circumvoluted the gestational-sac was unclear in 4 cases by transvaginal two-dimensional ultrasound imaging and in 9 cases by three-dimensional ultrasound imaging joint TUI technique. And‘interstitial line’ sign appeared in 4 cases showed by transvaginal two-dimensional ultrasound imagingwhile 6 cases by three-dimensional ultrasound imaging joint TUI technique. (3) Cases missed diagnosed and misdiagnosed:8 cases of early ectopic pregnancy were missed diagnosed both by transvaginal two-dimensional ultrasound imaging and three-dimensional ultrasound imaging joint TUI. The reasons we concluded were as follow:‘false gestational-sac’ located in the uterine cavity;the location of the gestational-sac was so closed to uterine cavity. Four cases of tubal pregnancy and 4 cases of uterine cornual pregnancy were misdiagnosed by transvaginal two-dimensional ultrasound imaging. The location of the ectopic pregnancy mass and the gestational-sac of 7 cases of uterine cornual pregnancy were clearly showed by three-dimensional ultrasound imaging joint TUI and only 1 case was misdiagnosed. Conclusions Transvaginal three-dimensional ultrasound imaging combined with TUI technique can provide more detailed ultrasound diagnostic information and reduced missed diagnosis and misdiagnosis of the early ectopic pregnancy. The clinical application value of transvaginal three-dimensional ultrasound imaging combined with TUI technique in the diagnosis of early ectopic pregnancy was good.

Objective To analyze the expression of serum anti M phospholipase A2 receptor (PLA2R)antibody in idiopathic membranous nephropathy (IMN),and to investigate its value in the diagnosis and evaluation of idiopathic membranous ne-phropathy.Methods One hundred and eighteen patients with biopsy-proved glomerular diseases were involved in this study, including 97 cases with IMN,21 cases with IgA nephropathy (IgAN)and 19 healthy people.ELISA was used to detect ser-um anti-PLA2R antibodies.Correlations of anti-PLA2R antibody level with laboratory parameters,including serum albumin, 24-hour urine protein of IMN patients were evaluated.Results The median of anti PLA2R antibody in IMN group,IgAN group and healthy group was 45.2(3.6~705.9)RU/ml,5.9(2.3~10.6)RU/ml and 1.2(0.6~9.3)RU/ml.The levels of serum anti PLA2R antibody in IMN group were higher than those in IgA nephropathy group and healthy control group.The difference was statistically significant (t=-5.027,-3.077;P=0.05).Among 97 cases with IMN,76 cases showed posi-tive anti-PLA2R antibodies (positive rate 78.35%).There was none patient showed positive anti-PLA2R antibody respec-tively in IgAN and healthy people.Furthermore,anti-PLA2R antibody level was negatively correlated with serum albumin (r=-0.453,P=0.000)and positively correlated with CREA,TC,ESR,24 hour urine protein (r=0.233,0.234,0.363, 0.586;P=0.004,0.217,0.021,0.000)in IMN patients.Conclusion Serum anti PLA2R antibody may be used as a IMN specific marker for the diagnosis of IMN,and it has important reference value for evaluating the severity of IMN.

Purpose To retrospectively analyze and summarize the image features of rare ovarian clear cell carcinoma (OCCC), and to provide basis for clinical diagnosis. Materials and Methods CT and MRI features of 30 cases of OCCC confirmed by pathology were retrospectively analyzed. Sixteen of all the patients underwent pre- and post-contrast CT scan. And 14 patients underwent pre- and post-contrast MRI scans. Results ① CT features: unilateral mass was revealed in 15 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 8 to 23.7 cm, mean (12.86±3.96) cm. One mass was irregular, 4 masses revealed incomplete capsule, and 4 masses had septa in the mass. CT value of cystic part of the mass was 20-30 HU, and which of solid part was 28-53 HU. On post-contrast CT images, the septa and solid component of the mass showed marked enhancement and delay enhancement, while the cystic component showed no enhancement. ② MRI features: Unilateral mass was revealed in 13 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 9.2 to 30.0 cm, mean (14.03±4.72) cm. One mass was irregular, 2 masses revealed incomplete capsule, and 2 masses had septa in the mass. The cystic component showed heterogenous signal intensity on T1WI, and high signal intensity on T2WI. There was no enhancement on post-contrast images. The solid component showed iso-intensity on T1WI, high signal intensity on T2WI, and diffused restricted on diffusion-weighted images. There was markedly enhancement on post-contrast images. ③ Blood supply of the tumor: In 8 cases, the branch of enlarged ipsilateral ovarian artery fed the tumors. In other 16 cases, the masses were surrounded by enlarged ipsilateral ovarian vein. Conclusion The characteristic CT and MRI features of OCCC include: a cystic solid mass with complete capsule; the solid component projects into the cavity, which could be hypervascular and marked enhanced.
