OBJECTIVETo evaluate and compare the effect of naso-intestinal tube decompression and octreotide in conservative management of early post-operative inflammatory ileus (EPII).

METHODSFrom March 2005 to January 2009, forty-five patients diagnosed with EPII, who failed to improve with conventional conservative management including nasogastric tube decompression, were enrolled in this study. All patients were prospectively nonrandomized into naso-intestinal tube group (n = 23) or Octreotide group (n = 22). The outcomes were compared between nasogastric tube, naso-intestinal tube and Octreotide groups.

RESULTSAll the forty-five patients with EPII refractory to conservative management with nasogastric decompression were treated successfully with the naso-intestinal tube decompression or octreotide in 3-12 days. Compared with the Octreotide group, the first passage of flatus was earlier [(4.7 +/- 1.9) d vs (6.7 +/- 1.6) d] and abdominal circumference recovered faster [(90.4 +/- 2.0)% vs (95.1 +/- 1.3)%] in the naso-intestinal tube group (P < 0.05). But the volume of cumulative and daily gastrointestinal decompression were more in naso-intestinal tube group than those in Octreotide group [(4037 +/- 1155) ml vs (3316 +/- 1038) ml; (890 +/- 181) ml vs (492 +/- 83) ml; P < 0.05].

CONCLUSIONSPatients with EPII could be safely and effectively managed by naso-intestinal tube decompression or octreotide. It is possible for those patients to avoid second laparotomy. Naso-intestinal tube decompression and octreotide are associated with faster recovery and less fluid loss respectively.

OBJECTIVETo determine genetic cause for a patient with development delay and multiple congenital anomalies.

METHODSRoutine karyotype analysis was performed for the patient and his parents. Array comparative genomic hybridization (array CGH) was performed for the patient to detect cryptic chromosome aberration.

RESULTSKaryotype analysis revealed no obvious anomaly for the patient and his parents. Array CGH has detected a 2.8 Mb heterozygous deletion at 9q34.3 and an 8.1 Mb heterozygous duplication at 22q. Fluorescence in situ hybridization analysis of the patient revealed an unbalanced subtelomeric translocation 46, XY, der(9) t(9; 22) (q34.3; q13.2q13.33) mat, which has resulted in partial trisomy 22q and partial monosomy 9q. Clinical features of the patient included developmental delay, facial dysmorphism and multiple congenital anomalies. Upon subsequent pregnancy, FISH analysis revealed that the fetus has inherited the normal chromosomes 9 and 22 from his mother. Postnatal follow-up confirmed normal development milestone and physiques in the child.

CONCLUSIONAn unbalanced translocation involving 9q and 22q has been found in a child featuring multiple congenital anomalies, which is due to a balanced translocation 9; 22 in his mother. Array CGH and FISH have also helped with discovery of subtelomeric rearrangement. Prenatal diagnosis of this aberration in subsequent pregnancies with FISH can prevent the recurrence of this disease.

OBJECTIVETo investigate the value of liver transplantation for late hepatocellular carcinoma.

METHODSThirty-six patients were treated by liver transplantation from August 2000 to February 2002, of which 15 patients had had advanced hepatocellular carcinoma and thirteen of these 15 patients were evaluated for results.

RESULTSThe 1-year survival rate was 86% (6/7). Only one patient died of recurrence within 6 months. The tumor-free survival was 5 to 19 months. Till February 2002, two patients have survived for 10 months and 19 months with recurrence.

CONCLUSIONIn our country, if the patients can afford liver transplantation, advanced hepatocellular carcinoma without extrahepatic metastasis is still indicated for liver transplantation, since some patients may survive relatively long.

BACKGROUND: Bone defects are one of the most important challenges that surgeons have to manage in total knee arthroplasty. The reasonable treatment method can guarantee the effect of the repair operation. OBJECTIVE: To review the relevant literatures concerning bone defects treated by primary total knee arthroplasty and revision total knee arthroplasty, and to analyze the optimal managements for different types of bone defects. METHODS: Relevant literatures were identified in China National Knowledge Infrastructure, Wanfang data, Vip, PubMed, Medline, and Web of Science. The key words were "total knee arthroplasty, total knee replacement, revision total knee arthroplasty, bone loss, bone defect, bone deficiency, management". The included studies were analyzed and summarized. RESULTS AND CONCLUSION: (1) Sixty-two studies regarding total knee arthroplasty for bone defects were included, without recognized standards on the type of bone defects. AORI is the most widely used classification for bone defects. (2) Pre-operated detailed evaluation including laboratory and radiographic examination, and accurate diagnosis are the key to success. (3) Management of bone defect was similar in tibia and femur, but there is still no standard classification and management of patellar bone defect. (4) Using stem fixation whenever a femoral or tibial component is revised can improve clinical outcome. (5) Through detailed evaluation, accurate diagnose and appropriate classification of bone defect, selection, according to the characteristics of different strategies, the age of the patient and the needs of life, can get a good clinical result.

BACKGROUNDThe FIP1L1-PDGFRalpha fusion gene plays an important role in the pathogenesis of chronic eosinophilic leukemia (CEL) and is a direct therapeutic target of the tyrosine kinase inhibitor imatinib mesylate.

METHODSIn 24 hypereosinophilic syndromes (HES) patients, using reverse transcriptase-polymerase chain reaction (RT-PCR), nested PCR and sequence analysis, we investigated the frequency of FIP1L1-PDGFRalpha and other abnormalities of tyrosine kinase family genes like PDGFRalpha, PDGFRbeta, C-KIT, FGFR1, ABL and FLT3 as well as gene mutation "hotspots", like MPL515 and JAK2V617F, frequently involved in myeloproliferative diseases. Fluorescence in situ hybridization was used to confirm the 4q12 deletion.

RESULTSThe FIP1L1-PDGFRalpha fusion transcript was found in 8 (33%) of 24 patients with HES, corresponding to the chromosome 4q12 deletion identified by FISH. The FIP1L1-PDGFRalpha-associated patients diagnosed with CEL, frequently had hepatosplenomegaly, eosinophil-related tissue damage, anemia, thrombocytopenia, myelofibrosis and a short overall survival time. Nevertheless, imatinib mesylate induced rapid and complete hematological responses in treated FIP1L1-PDGFRalpha cases, followed by molecular remission and reversal of myelofibrosis. FIP1L1-PDGFRalpha fusion could co-exist with other mutations of tyrosine kinase family genes, like FLT3 or PDGFRbeta. We also demonstrated that the SNPs of PDGFRbeta were associated with selective splicing of exon 19 in case 20.

CONCLUSIONSCorrelating the CEL genotype with phenotype, FIP1L1-PDGFRalpha emerges as a relatively homogeneous clinicobiological entity that co-exists with other abnormalities of tyrosine kinase family genes. It reflects the disease progression and there is a good response to imatinib. Detection of the FIP1L1-PDGFRalpha fusion gene is valid for both CEL diagnosis and therapy surveillance.

OBJECTIVETo evaluate the outcome of endovascular stent graft placement in patients with acute thoracic aortic syndromes.

METHODSEmergency stent-graft implantations were performed in 57 patients with acute thoracic aortic syndromes from May 2001 to December 2005 (45 Stanford B aortic dissections, 9 acute penetrating aortic ulcers or pseudoaneurysms. 3 traumatic thoracic aneurysms). The clinical data, efficacy and follow-up results were analyzed.

RESULTSProcedures were successful in all patients. Type I endoleaks were evidenced in 5 patients and ascending aortic dissection occurred in 1 patient during operation, 5 patients with acute penetrating aortic ulcer complicating with coronary artery disease received successful PCI immediately post endovascular stent graft placement. Adynamia in extremities occurred in 1 patient and recovered two days later post anisodamine and mcnicol treatments. Left vertebral artery ischemia was found in 1 patient due to coated subclavian artery by stent-graft and the patient recovered spontaneously after two days lethargy without special treatment. The mean ICU time after surgery was 3.5 days (1 - 8 days) and the mean hospitalization time was 10 days. The mean follow-up time was 25.30 +/- 13.1 months (1 - 47 months). Two patients died within 30 days after operation, 1 patient died of rupture of the ascending aortic dissection (7 days post operation), 1 patient died of acute renal failure at the 2nd day post operation. One patient died of empsyxis 3 months after procedure, 1 patient died at the 4th month post procedure for unknown reason, 1 patient received second stent-graft implantation because of a newly formed endoleak at the proximal end of the stent-graft, 5 patients received second stent-graft implantation because of newly formed leaks at the remote end of the stent-graft. No paraplegia or stent migration or stenosis was observed during the follow up period. Total mortality during hospitalization and follow-up was 7.0%.

CONCLUSIONPatients with acute thoracic aortic syndrome could be effectively and safely treated by coated stent-graft endovascular placement.

S:Background Seroma formation is one of the most common complications after breast cancer surgery. Various risk factors have been evaluated for their associations with the development of seromas in Western populations. However,similar data are not available in Chinese series. Therefore, we sought to investigate the potential risk factors for Chinese breast cancer patients.Methods A prospective study of female breast cancer patients undergoing surgery was carried out in Cancer Hospital of Fudan Unversity, Shanghai, China. Univariate analyses were performed by chi-square test or Student's t test or Mann-Whitney test and multivariate analyses by stepwise Logistic regression. The logistic model included age (years),total serum protein concentration (g/L), drainage volume on postoperative day 3 (POD 3; ml) and time to daily drainage volume not more than 30 ml (TTV30; days).Results A total of 158 patients with breast cancer were studied. The mean age at diagnosis was (52.14±10.77) years (range 25-92). During the follow-up period, 24 (15.2%) patients developed seromas. Calculated as continuous variables in the stepwise Logistic regression, age (OR=1.090, 95% CI 1.028-1.155, P=0.004), total serum protein concentration (OR=0.886, 95% Cl 0.791-0.992, P=0.036), drainage volume on POD3 (OR=1.013, 95% CI 1.002-1.023, P=0.017) and TTV30 (OR=1.273, 95% CI 1.039-1.561, P=0.020) were independent risk factors for seroma formation. Additionally,significant difference in daily drainage volume was substantiated in the analysis by seroma formation (P=0.034) rather than by type of surgery (P=0.713).Conclusions Although the pathogenesis of seroma remains controversial, such risk factors as age, nutritional status,drainage volume on POD3 and TTV30 should be considered for prediction and prevention of seroma formation in Chinese breast cancer patients.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.
