Objective To investigate the influence of the lymph node micrometastasis and its clinicopathological features on postoperative disease-free survival rate for patients with gastric cancer.Methods The study included 120 patients with pT1-3NoMo gastric cancer. The relationships between clinicopathological features or carcinoembryonic antigen (CEA) positive expression and postoperative disease-free survival rate were analyzed. Results In clinicopathological factors, multivariate analysis identified CEA positive expression was significantly correlated with tumor diameter (P = 0.011 ),depth of tumor invasion (P= 0.027) and lymphatic vessel invasion (P= 0.001 ) in lymph node positively. The average postoperative follow-up was (53.14 ± 16.75) months. There was statistical correlation between the tumor diameter( P = 0.018 ) or depth of tumor invasion ( P = 0.015 ) and postoperative disease-free survival rate. The disease-free survival rate was 90.91% ( 80/88 ), 86.36% ( 19/22 )and 40.00% (4/10) for the lymph node CEA negative,isolated tumor cells (IT Cs) and micrometastasis,respectively. There was significant difference between micrometastasis and the lymph node CEA negative (P= 0.000) or ITCs (P = 0.009), however, the lymph node CEA negative and ITCs was no significant difference (P = 0.438 ). Lymph node micrometastssis of gastric cancer was detected in 10 patients who should belong to stage pN1,the restage rate was 8.33%(10/120). Conclusions If the patients were found micrometastasis in lymph node with high-risk stage pT1-3NoMo gastric cancer for whom chemotherapy may be recommended,because of its high recurrence and poor prognosis.

Objective To explore the causes and risk factors affecting early death in patients with traumatic cervical spinal cord injury (SCI). Methods Clinical data of 553 patients with traumatic cervical SCI were analyzed retrospectively to discuss the related factors affecting early death of patients with traumatic cervical SCI by using univariate analysis and multivariate logistic regression analysis. Results The early mortality of the patients with traumatic cervical SCI was 4.0% ( 22/553 ). The main causes of the early death were respiratory failure in nine patients (40.9%) and electrolyte disorders in five (22.7%). Univariate analysis showed that age, cervical spinal cord injury severity, complications in respiratory, cardiovascular, digestive systems and electrolyte disturbance as well as tracheotomy were considered statistically significant for early death in patients with traumatic cervical SCI ( P < 0, 05 ). Multivariate logistic regression analysis showed that age, cervical SCI severity, complications in respiratory,cardiovascular system and electrolyte disturbance as well as tracheotomy. Conclusion Severe cervical SCI, combined respiratory, cardiovascular system and electrolyte disorder complications as well as tracheotomy are high risk factors for the early death in patients with traumatic cervical SCI.

Objective To compare and evaluate the clinical efficacy and side effect of vinorelbine plus gemcitabine and vinorelbine plus cisplatin combinations in advanced non-small-cell lung cancer(NSCLC). Methods 56 cases with non-treated advanced NSCLC were unrandomly divided into two groups: the GN group (27patients) treated with vinorelbine plus gemcitabine, the NP group (29 patients) treated with vinorelbine plus cisplatin,1/3 weeks×2～6 cycles. Results For the GN group, the overall response rate was 37.7 %, MTTP was 5.1months,one year survival rate (1-ySR) was 40.7 %. There were no significant difference in the response rates and the survival rates for the GN group compared with the NP group (P ＞0.05); But on the side effect of toxicities, WHO grade anemia and nausea/vomiting and tiredness of the GN group was significantly milder than the NP group (P ＜ 0.05). Conclusion Vinorelbine combined Gemcitabine regimen (GN) is active and well-tolerated. It is worth to investigate GN recommended as the first line chemotherapeutic regimen for the treatment of patients with advanced NSCLC.

Objective To explore the clinical features of chronic granulomatous diseases and Mcleod syndrome caused by continuous X chromosome deletion. Methods The clinical data of two children diagnosed as chronic granulomatous disease and Mcleod syndrome by gene detection were retrospectively analyzed. Results Two males, 4 year 1 month and 1 year 9 month old, were both hospitalized due to persistent pulmonary infections. Both of them had a history of repeated severe infections and BCG vaccine associated lymphadenitis, and were diagnosed as X-linked chronic granulomatous disease for respiratory burst defects and deletion of all CYBB exons. Both of them had retarded motor development, and were diagnosed as DMD for detection of DMD gene exons and muscle speciifc promoter region and exon 1-2 deletion by MLPA. One case was found with obvious echinocytes, the other case showed whole exons deletion of XK gene. Both of them were diagnosed as Mcleod syndrome. Conclusion Continuous X chromosome deletion could lead to combination of Mcleod syndrome, DMD, and X-CGD, which may complicate the condition. Due to the lack of Kx antigen, repeated common blood transfusion can produce relative antibody, which lead to severe hemolytic crisis.

Objective To assess the value of transesophageal echocardiography (TEE) in left atrial appendage (LAA) closer with Amplatzer Cardiac Plug (ACP).Methods Consecutive 32 atrial fibrillation patients (CHADS2≥1) with high risk bleeding underwent LAA occlusion with ACP LAA occlusion device under the guidance of TEE.Measurements of LAA anchoring area diameter (AAD) and LAA anatomical orifice diameter (AOD) including maximum,minimum values,and LAA depth on 2 dimentional TEE (2D TEE) were conducted before closer device implantation.The outcomes of LAA occlusion were analyzed.Results Among 32 patients,27 cases achieved successful LAA occlusion,including 2 cases with peripheral leakage ≤5 mm,and 5 cases failed occlusion.Among 5 failed closed patients,3 cases with LAA AAD≥ 30 mm,1 case with LAA of short depth,and 1 case with anatomical variation of LAA of low position that access sheath could not be positioned in the LAA.LAA AAD maximum,minimum and LAA depth were (25.9±4.9)mm,(20.0±3.8)mm,(31.0±5.6)mm,respectively,and LAA AOD maximum,minimum diameters were (26.2±6.2)mm,(19.4±4.3)mm,respectively.Among 10 cases with LAA AAD≥30 mm,7 cases achieved successful LAA occlusion,but 3 cases failed.The implanted device diameter was (26.4±3.8)mm,and device compression rate was (7.6±5.5)%.The coefficient of correlation between device diameter and large LAA AAD and AOD is 0.770 and 0.717,respectively.There was no complication but 1 case with pericardial effusion.Conclusions Two dimentional TEE measurements of LAA have clinical guiding significance in the selection of proper size of ACP LAA occluder.The AAD of 2D TEE has the good correlation with ACP occluder′s size,the AADs are important factors which affect the success of LAA occlusion.

Objective To improve the understanding of neonatal-onset pulmonary tuberculosis.Methods The clinical features,laboratory examination and imaging were analyzed in 2 cases with neonatal-onset pulmonary tuberculosis in the Respiratory Department of Beijing Children's Hospital,Capital Medical University.Results The 2 patients were premature twins,were born at 33 +3 weeks of gestation,presented with intermittent cough and transient fever on 26 days after birth.Chest CT scan showed pulmonary multifocal nodules.One case was complicated with pleural effusion,atelectasis and no effectiveness with antibiotics.The untypical pathogen infection was considered.The result of PPD was negative,the result of interferon gamma release array,gastric acid fast staining and mycobacterium tuberculosis culture were positive,finally they were diagnosed with pulmonary tuberculosis.Conclusions The clinical features and imaging of neonatal tuberculosis are always untypical and PPD is negative,which brings difficulties to clinical diagnosis.We should take untypical pathogens into account,such as tuberculosis,when some diseases cannot be explained by common pathogens.

ObjectiveTo investigate the characteristics of traumatic spinal cord injury (TSCI) urban inpatients of Tianjin in 2007. MethodsInpatients with TSCI of 8 hospitals in Tianjin in 2007 were reviewed. ResultsThere were 73 patients in total. Mean age was (51.34±14.597) years. Male∶Female was 3.56∶1. Falling, motor vehicle accidents （MVC） were the main causes of TSCI. The cervical spinal cord injuries were predominant. 26% were complete injury and 74% were incomplete. 6 cases were dead. Patients with ASIA grade D recover well. ConclusionFor the TSCI, the ages of patients increases and falling is the main cause.

Objective To compare the therapeutic effect of Midodrine hydrochloride plus oral rehydration salts,Metoprolol plus oral rehydration salts and simple oral rehydration salts on children with postural tachycardia syn-drome(POTS). Methods One hundred and ninety - two children with POTS were divided into Midodrine hydrochlo-ride plus oral rehydration salts group(84 cases),Metoprolol plus oral rehydration salts group(54 cases)and oral rehy-dration salts group(54 cases). The patients were followed up at the outpatient department after 3 - months treatment. Short - term effect was analyzed by reevaluating the symptom scores,repeating upright test and studying the side effects of the drugs. All the children were followed - up by telephone,mainly investigating on the syndrome recurrence and symptom - free survival by Kaplan - Meier analysis. The follow - up time was 3 to 122(42. 7 ± 24. 3)months. Results Short - term effect showed that the symptom scores were decreased after treatment(t = 21. 536,P ﹤ 0. 001). Head -up test showed that delta heart rate was decreased. The effective rates in the Midodrine hydrochloride plus oral rehydra-tion salts group and the Metoprolol plus oral rehydration salts group were significantly higher than those of the simple oral rehydration salts group(χ2 = 10. 905,P = 0. 004). But no statistical difference was found between the Midodrine hydrochloride plus oral rehydration salts group and the Metoprolol plus oral rehydration salts group(χ2 = 0. 042,P =0. 837). Long - term effect by Kaplan - Meier curve showed that the therapeutic effect of Midodrine hydrochloride plus oral rehydration salts group was significantly higher than any of the other two groups(χ2 = 13. 299,P ﹤ 0. 01),but no statistical difference was found between the Metoprolol plus oral rehydration salts group and the simple oral rehydration salts group(χ2 = 0. 150,P = 0. 699). Conclusions In terms of the short - term result,the effective rates in the Mido-drine hydrochloride plus oral rehydration salts group and the Metoprolol plus oral rehydration salts group were signifi-cantly higher than those of the simple oral rehydration salts group. The therapeutic effect of the Midodrine hydrochloride plus oral rehydration salts was superior to that of the Metoprolol plus oral rehydration salts and the simple oral rehydra-tion salts for POTS children by the long - term follow - up study.
