Objective According to the characteristics of digital medicine and demand of digitized management in hospital, we establish a storage system which is cheap, highly expansible, and reliable. Methods The multi personal computer storage system (MPCSS) was constructed by assembling the hardwares and softwares. The image data were archived from major server to storage PC by using NEUSOFT PACS archiving manage system and backuped on storage PC. We simulated the situation that the data on storage PC was lost and restored the data. We also expanded the storage system to enlarge its capacity. Results Average transfer rate from MPCSS was 27 7 Mbit/s (1 byte=8 bit); average cost for this system was 74 RMB/G; six cases in the 187 repeated reading of 100 patients failed. MPCSS can store backup and restore the image data, and can expand the storage size. Conclusion MPCSS is very cheap compared with other high capacity systems or devices. It is feasible and suitable for digital image storage.

To investigate the scientificity of patient-reported outcome (PRO) scale for myasthenia gravis (MG), which was used to evaluate the clinical effects of traditional Chinese and Western medicine treatment on MG patients. Psychometric performance of the MG-PRO scale was also expected to be evaluated in this study.

Objective To investigate the expression and the effects of tissue inhibitor of metalloproteinases-1 (TIMP-1) on lungs of rats with sepsis.Methods Forty Sprague-Dawley (SD) rats were randomly divided into two groups,namely sham group (n =8) and sepsis model group (n =32).The rats of model group were modeled by cecal ligation and puncture (CLP),and were further divided into four subgroups as per the time after modeling,namely 6 h (n =8),12 h (n =8),24 h (n =8),48 h (n =8)subgroups.Blood and lung samples were taken 6 h,12 h,24 h and 48 h after modeling.The histological changes in lungs of the rats were observed under light microscope.Expressions of TIMP-1 mRNA,Bax mRNA and Bcl-2 mRNA in lungs were measured by RT-PCR.The immunohistochemistry was used to label the CD18 in lungs during different phases of sepsis.The data were processed by t test.Results Compared with sham group,the lung tissues of rats in model group were injured to a certain extent after CLP.The expression of TIMP-1 mRNA and the number of CD18 positive cells increased at the same time (P ＜ 0.01),and peaked 24 hours later (P ＜ 0.01).While the expression of Bax mRNA in model group decreased markedly 12-48 hours after modeling (P ＜ 0.01-0.05),and reached minimum 48 hours later (P ＜ 0.01).The expression of Bcl-2 mRNA in model group changed unnoticeable.The positive correlation between variations in number of CD18 positive cells and expression of TIMP-1 mRNA was found in model group (r =0.426,P ＜ 0.01).Conclusions The increase in expression of TIMP-1 mRNA in lungs is closely associated with the lung injury of sepsis.The mechanism of lung injury is likely attributed to the preservation of inflammatory cells from apoptosis,and the persistent inflammation response causes tissue damage,leading to organ dysfunction.

Background and purpose:For stageⅠ non-small cell lung cancer (NSCLC), video-assisted thoracic segmentectomy is given much attention to by thoracic surgeon because of the less tissue damages. However, video-assisted thoracic lobectomy is still considered as the standard treatment in the world. Therefore, this study was to evaluate the clinical effect after video-assisted thoracic segmentectomy and lobectomy in patients with stageⅠ NSCLC in order to provide reference for clinical application.Methods:The comparative studies on video-assisted thoracic segmentectomy and lobectomy treating stage I NSCLC were retrieved from PubMed, Web of Science, EMBASE, the Cochrane Library, CNKI, CBM, VIP, and Wanfang Data. All data were acquired until July 2015. Literature screening according to data extraction and quality assessment was completed by two reviewers independently. Meta-analysis was conducted by RevMan 5.3 software which was offered by Cochrane network.Results:A total of 11 articles involving 1 677 patients were ifnally included. The results of meta-analysis indicated that: for stageⅠ NSCLC, compared with video-assisted thoracic lobectomy, the effect of video-assisted thoracic segmentectomy was alike in total mortality (OR=0.77, 95%CI: 0.48 to 1.21,P=0.25), 5-year mortality (OR=0.77, 95%CI: 0.52 to 1.14,P=0.19) and systemic complications (OR=0.76, 95%CI: 0.53 to 1.09,P=0.13), but could reduce blood loss [difference in means (MD)=-41.16, 95%CI: -59.46 to -22.86,P<0.000 1], chest tube duration (MD=-0.29, 95%CI: -0.49 to -0.09,P=0.005) and the length of hospital stay (MD=-0.74, 95%CI: -1.44 to -0.05,P=0.04).Conclusion:Compared with video-assisted thoracic lobectomy, video-assisted thoracic segmentectomy can signiifcantly reduce blood loss, chest tube duration and length of hospital stay. However, the two kinds of operation methods achieved the same effects on the total mortality, 5-year mortality and systemic complications. Thoracoscopic segmentectomy may be an alternative to thoracic lobectomy.

Objective To investigate the differential diagnostic value of computed tomography (CT) combined with serum tumor markers in borderline ovarian tumors (BOT) and benign epithelial ovarian tumors (BET).Methods The CT data in 28 patients with BOT and 41 patients with BET,both confirmed by surgery and pathological,were analyzed retrospectively.Their preoperative serum carbohydrate antigen 125 (CA125),human epididymis secretory protein 4 (HE4) and carcinoembryonic antigen (CEA) detection results were collected.The CT images features and serum tumor markers levels were compared between the two groups.Results The difference in the appearance rate of tumor solid composition,thick septum and wall nodule between the two groups had statistical significance (x2 =25.135,5.240,5.066,P＜0.05).The serum CA125 level had statistical difference between the two groups (Z=3.202,P＜0.05),while serum HE4 and CEA levels had no statistically significant difference between the two groups(Z=0.330,1.122,P＞0.05).The optimal critical value,sensitivity and specificity of serum CA125 level in differential diagnosis of two kinds of tumor was 42.45 U/mL,53.6％ and 85.4％.The overall diagnostic rate of solid composition and thick septum for diagnosing the two kinds of tumor was 78.5 ％.The overall diagnostic rate of solid composition,thick septum and CA125 level for diagnosing the two kinds of tumor was 81.2％.Conclusion The appearance of solid composition,thick septum and serum CA125 level increase in epithelial ovarian tumor may help to identify BOT and BET.

Objective To explore the perioperative management and surgical outcomes of fracture-dislocation of the upper cervical spine complicated with vertebral artery injury.Methods We retrospectively analyzed the clinical data of 19 patients diagnosed with fracture-dislocation of the upper cervical spine complicated with vertebral artery injury who had been treated at our department from January 2008 through December 2012.They were 14 males and 5 females,aged from 22 to 53 years (mean,35.2 years).All the patients had fractures of the atlas and/or axis,and disordered atlanto-axial relationship as well.According to Frankel grading system,8 cases were Grade D and 11 Grade E.The cervical posterior fixation with pedicle screws was adopted for all and hemostasis was conducted for those with bleeding from the broken vertebral artery.Their Frankel grade,Japanese Orthopedic Association (JOA) score and visual analogue scale (VAS) score were compared between preoperation and final follow-up.Results Intraoperative hemorrhage occurred in 2 patients from the injured vertebral artery.Hemostasis was achieved through direct tamponade with bone wax and gelatin sponge in one and through endovascular intervention after bleeding control by direct tamponade in another.Neither of them presented with symptoms of posterior circulation ischemia after operation.The mean operation time was 153.5 min,and the mean blood loss was 542.1 mL.All the patients were followed up for an average time of 28 months.Bony union was obtained in all after an average time of 13.5 weeks.Follow-ups revealed no ischemic stroke in this series.Symptoms of transient ischemic attack,like transient dizziness and blurred vision,appeared in 2 patients.At the final follow-up,all the patients were assessed as Frankel Grade E.Their mean JOA and VAS scores were significantly improved from 8.1 ± 1.2 and 7.0 ± 1.7 preoperatively to 12.7 ± 1.6 and 1.3 ± 1.2,respectively (P ＜ 0.05).Conclusions Angiography examination is routinely indicated for the patients with fracture-dislocation of the upper cervical spine perioperatively.Preoperative evaluation of the vertebral artery and its adjacent structures and effective intraoperative hemostasis can avoid uncontrollable bleeding during operation,reduce postoperative complications,and improve surgical outcomes.

OBJECTIVEAccording to the characteristics of digital medicine and the demands of digitalized management in hospitals, we established a storage system that is affordable, highly expandable, and reliable.

METHODSThe multi personal computer storage system (MPCSS) was constructed using hardware and software. The image data were archived from major servers to storage personal computers (PCs) by using Neusoft-picture archiving and communication system (PACS) and backed up on storage PCs. We simulated data loss on storage PCs and then restored the data. We also expanded the storage system to enlarge its capacity.

RESULTSThe average transfer rate from MPCSS was 27.7 MB/s, and the average cost for this system was yen 74/GB. In the testing stage, only 6 of 187 instances of data retrieval (from 100 patients) failed.

CONCLUSIONThe MPCSS is much less expensive than other high capacity systems or devices. It is feasible and suitable for digital image storage.

OBJECTIVE: To investigate the relationship between behavioral changes and cell proliferation in subventricular zone (SVZ) after intracerebral hemorrhage (ICH) in adult rats. METHODS: Forty male Sprague-Dawley rats were randomly assigned into a behavioral test group (n = 19) and a bromodeoxyuridine (Brdu) immunohistochemical staining group (n = 21). ICH was induced by stereotactial injection of collagenase type VII into straitum. Proliferating cells were labeled by injection intrapenitoneally of bromodeoxyuridine in a pulse protocal. Rats were killed on day 2, 7, 14, and 28 after the ICH. Behavioral test and bromodeoxyuridine immunohistochemical staining were performed.Behavioral change was tested by forelimb placing test, Berderson's grade and corner turn test in rats. Cell counting of bromodeoxyuridine immunoreactive cells in SVZ was performed. RESULTS: There were marked neurological deficits by day 2 after the ICH, with progressive recovery of function over 4 weeks. A significant increase in the number of bromodeoxyuridine immunoreactive cells in the ipsilateral and cortralateral SVZ was observed from 2 to 14 days with a peak at day 7 after the ICH compared with the sham group.The bromodeoxyuridine immunoreactive cells decreased to control level 28 days after the ICH. CONCLUSION Proliferation of cells in SVZ corresponds well with behavioral recovery after the ICH, which indicates SVZ cells may be involved in the repairing process after the ICH.
