BACKGROUNDThe aim of this study was to prospectively study the changes in neutrophil elastase (NE), fibroblast growth factor 9 (Fgf9), matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase 1 (TIMP-1) in sputum induced during the early period after lung volume reduction surgery (LVRS).

METHODSFrom April to October 2005, ten consecutive patients with chronic obstructive pulmonary disease (COPD) underwent LVRS. Ten non-small cell lung cancer patients (stage II - IIIa) received lobectomy as a control group. The induced sputum was collected from both groups at six different times (two weeks before operation and postoperatively at 1, 2, 4, 6 and 10 days). The level of NE, Fgf9, MMP-9 and TIMP-1 were measured using enzyme-linked immunosorbent assay.

RESULTSThe pulmonary function (FEV(1)%) and arterial blood gases (PaO(2) and PaCO(2)) were significantly different between the groups. There were no significant differences in age, ejection fraction (EF), and operation duration, but hemoglobin in the LVRS group was statistically higher than in the controls. At certain times, there were significant differences in NE, MMP-9, TIMP-1 and MMP-9/TIMP-1 (P < 0.05) but not in Fgf9 between the two groups. The levels of NE and TIMP-1 were maximal at 2 days postoperatively and that of MMP-9 and MMP-9/TIMP-1 at 4 days postoperatively in the LVRS group. In the control group, maximal levels of NE and TIMP-1 occurred at 2 days postoperatively and that of MMP-9 and MMP-9/TIMP-1 at 1 day postoperatively. Ten days after surgery, all values of the control group were not significantly different from the baseline. In the LVRS group, the levels were significantly different from the pre-operative values (P < 0.05) apart from TIMP-1.

CONCLUSIONThe levels of NE, MMP-9, TIMP-1 and MMP-9/TIMP-1 of the LVRS group were different from those of the control group. The time course of these changes may be related to LVRS and the underlying process of COPD.

OBJECTIVEUsing pulsed field gel electrophoresis (PFGE) and polymerase chain reaction (PCR) typing to analyze strains isolated from two outbreaks caused by Shigella sonnei and to trace the source of infection.

METHODSVirulence genes ipaH and ial were detected by PCR and PFGE was used to subtype the isolates. Patterns were compared, using the software BioNumerics.

RESULTSWithin the 54 isolates, all were ipaH positive with 48 as ial positive. Strains from the Chongzhou outbreak were clustered into 4 PFGE patterns, with the predominant pattern accounted for 72% of the analyzed strains. The pattern of strains isolated from the cold pork with sauce was identical to the predominant pattern. The strains from Dayi outbreak were clustered into 8 PFGE patterns and the predominant pattern accounted for 56% of the test strains.

CONCLUSIONStrains from the two outbreaks were quite different and the 'cold pork with sauce' seemed to be the major source of infection, causing the outbreak of diarrhea in Chongzhou. The sources of infection of the Dayi outbreak might be complicated whereas PFGE showed a discriminatory and reproducible laboratory tool in the epidemiologic investigation on outbreaks of diarrhea.

OBJECTIVEto present the preliminary results of minimally invasive Ivor Lewis esophagectomy using a circular-stapled anastomosis with trans-oral anvil technique.

METHODSsix patients with esophageal cancer received minimally invasive Ivor Lewis oesophagectomy from April 2010 to June 2010. There were 5 males and 1 female with mean age of 55 years (ranging 38 to 69 years). The lesion located in cardiac in 1 case, in lower third of the esophagus in 4 cases and in middle third in 1 case. The abdominal portion was operated laparoscopically. The thoracic portion was done using thoracoscopic techniques. The esophago-gastric anastomosis was created using a 25 mm anvil passed trans-orally and connected to a 90 cm long polyvinyl chloride delivery tube through an opening in the esophageal stump. The anastomosis was completed by joining the anvil to a circular stapler (end-to-end anastomosis stapler) inserted into the gastric conduit.

RESULTSsix patients with esophageal squamous cell cancer (n = 5) and small-cell cancer (n = 1) underwent an Ivor Lewis esophagectomy. All the operation was successfully performed without intra-operative technical failures of the anastomosis. There was no severe postoperative complications. The mean operation time was 380 min. The mean blood loss was 300 ml. pTNM staging: T2N0M0 in 3 cases, T2N1M0 in 1 case and T3N0M0 in 2 cases.

CONCLUSIONSthe circular-stapled anastomosis with the trans-oral anvil is an efficient and safe technique for esophago-gastric anastomosis.

To explore the clinical features, risk factors an d treatment of retinoic acid syndrome (RAS) in patients with acute promyelocytic leukemia (APL) treated with retinoic acid, the clinical and laboratory data of 11 APL patients with RAS were retrospectively analysed. The results showed that earlier and more common symptoms of RAS were successively dyspnea (11/11), fever (10/11) and hydrothorax (6/11). Higher WBC count (> or = 15.0 x 10(9)/L) in the course of treatment of all-trans retinoic acid susceptible to develop RAS (9/11). The RAS patients were treated with dexamethasone without discontinuing the treatment of retinoic acid, complete remission was achieved in 10 cases and one patient died from disseminated intravascular coagulation. It is concluded that the identification and dexamethasone treatment of RAS in earlier period are extremely important for obtaining better clinical curative effect, and it does not influence therapeutic effect of continuing application of retinoic acid.

BACKGROUNDMinimally invasive Ivor Lewis esophagectomy was usually performed with either hand-sewn or circular stapler anastomosis through a small thoracotomy or using a side-to-side stapler anastomotic technique. This study aimed to present our initial results of Ivor Lewis esophagectomy using a circular-stapled anastomosis with transoral anvil technique.

METHODSSix patients with esophageal cancer underwent minimally invasive Ivor Lewis esophagectomy with an intrathoracic circular-stapled end-to-end anastomosis. The abdominal portion was operated on laparoscopically, and the thoracic portion was done using thoracoscopic techniques. A 25 mm anvil connected to a 90 cm long delivery tube was introduced transorally to the esophageal stump in a tilted position, the anvil head was then connected to circular stapler. The anastomosis was completed under direct thoracoscopic view.

RESULTSA total of six patients in this report successfully underwent total laparoscopic and thoracoscopic Ivor Lewis esophagectomy with a circular-stapled anastomosis using a transoral anvil. They were five male and one female patients, and had a mean age of 55 years (range, 38-69 years). The thoracic and abdominal operations were successfully performed without any intraoperative complications or conversion to laparotomy or thoracotomy. The passage of the anvil head was technically easy and successful in all six cases. The mean overall operative time was (260 ± 42) minutes (range, 220-300 minutes), and the mean estimated blood loss was (520 ± 160) ml (range, 130-800 ml). Patients resumed a liquid oral diet on postoperative day seven. The median length of hospital stay was 17 days (range, 9-25 days). The postoperative pathological diagnosis was esophageal squamous cell carcinoma in five patients and esophageal small cell carcinoma in one patient. Tumors were staged as T(2)N(0)M(0) in three cases, T(2)N(1)M(0) in one case, and T(3)N(0)M(0) in two cases. During the mean follow-up of 2.5 months (range, 2-4 months), there were no intraoperative technical failure of the anastomosis or major postoperative complications such as leak or stricture.

CONCLUSIONSThe initial results of this small series suggest that minimally invasive Ivor Lewis esophagectomy for malignant esophageal tumor is technically feasible. However, further multi-center prospective studies and thorough evaluation are needed to evaluate the long-term results.

OBJECTIVETo study the relationship between expression of galectin-3 (Gal-3) and osteopontin (OPN) in occult metastasis in non-small cell lung cancer.

METHODSForty-six patients of non-small cell lung cancer (NSCLC) from January 2006 to October 2007 were selected. There were 28 males and 18 females, aged from 33 to 77 years old. The levels of lung tissues Gal-3 and OPN were detected by RT-PCR, and the levels of blood plasma's were measured by ELISA.

RESULTSThere were 12 patients who had metastasized. In un-metastasis group the Gal-3 and OPN mRNA expression levels were significantly lower than that in metastasis group: mean value were 0.07 +/- 0.17 and 0.17 +/- 0.25 in un-metastasis group, while 0.73 +/- 0.23 and 0.79 +/- 0.24 in metastasis group. Blood plasma levels of Gal-3 (18.8 +/- 7.9) microg/L and OPN (153.5 +/- 63.5) microg/L in NSCLC which were detected from metastasis group were higher than un-metastasis group of (9.2 +/- 5.6) microg/L and (89.2 +/- 24.0) microg/L.

CONCLUSIONSHigh serum levels of Gal-3 and OPN and high expression of Gal-3 and OPN mRNA in NSCLC are closely related to the occurrence and metastasis of NSCLC. They may be indexes of evaluating the occult metastasis in NSCLC.

Objective To observe the obstacle of mandible to the cervical spine with the aid of dual fluoroscopic imaging system, explore the optimal perspective Methods of in vivo kinematics of cervical spine, and verify the feasibility of cervical in vivo kinematic researches. Methods A dual fluoroscopic imaging system composed of two C-arms placed in different angles was utilized. X ray images of the cervical spine for five healthy volunteers (4 male, 1 female) with standing, flexion extension, twisting and bending positions were obtained with the C-arms in the angle of 90°, 60°and 45°, respectively. The obstacles of mandible to the cervical spine in different positions were compared and the obstacle degree of mandible to the cervical spine was evaluated to screen the optimal perspective Methods. The perspective images under conventional head rotation and coaxial trunk rotation were collected during cervical twisting to compare the obstacle of mandible to cervical images. Results There were significant differences in mandibular obstacle degrees among the three angles measured in standing, flexion-extension, twisting and bending positions（P<0.05）. With two C-arms in 45°, the cervical spine was best imaged with the least obstacle. With two C-arms in 60°, significant differences could be found between the coaxial trunk rotation and the head rotation group. Conclusions For in vivo kinematics study of cervical spine, the obstacle of mandible to the cervical spine can be minimized with C-arms of dual fluoroscopic imaging system in 45°, and the coaxial trunk rotation can decrease the mandibular obstacle degrees as compared with the head rotation, which satisfy the requirement of 2D-3D image matching.

BACKGROUND: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. MATERIALS AND METHODS: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. RESULTS: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86% (344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. CONCLUSION: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.
