Six patients with ST segment elevated acute myocardial infarction (AMI), who were 52.5 years old in average, were enrolled and performed the treatment at Tongren Hospital from November 2003 to June 2004. Following percutanecus transluminal coronary angioplasty and stent revascularization, autologous bone marrow stem cell (BMSC) transplantation was performed after informed consent was obtained. Patients were subcutaneously injected with granulocyte colony-stimulating factor (G-CSF) at 1 week before transplantation. When CD34+ cells going up to 1%-3% in peripheral blood, mononuclear cells in peripheral blood were harvested,purified, and further infused into the infarcted related coronary artery with an over-the-wire balloon catheter. Following up was performed every half a year. Four years later, the infarcted area of these patients was further decreased by 8.03%, in the basic descent of 42.7% at 3 months averagely; total infracted area descent was 50.73%, but ejection fraction increased by 4.6% from 50.8%. There was no serious coronary artery restenosis and/or stenosis formation which need revascularization upon angiography.

Objective To investigate the efficacy of the indocyanine green (ICG) clearance test (ICGR15) combined with the model for end-stage liver disease (MELD) for assessing the short-term prognosis of patients with liver failure.Methods Eighty patients with liver failure were analyzed retrospectively.ICGR15 and relevant clinical data within 24 hours of diagnosis were analyzed.Meanwhile,the MELD score and King's College Hospital (KCH) were evaluated.All findings were tested for correlation with 3-month mortality.Quantitative data were analyzed with analysis of variance and Student's t-test.Count data were analyzed with chi-square test.Correlation analysis was performed with Pearson's coefficient test.Results Among 80 patients with liver failure,39 patients survived and 41 died.The mortality rate of all patients was 51.2％.The serum total bilirubin,creainine concentrations,ICGR15,MELD scores and patient number in accordance with KCH criteria of surviving patients were (288.0±109.1) μmol/L,(63.3±24.4) μmol/L,(48.1±10.2)％,20.6±4.4,and 6 cases,respectively,which were lower than those in dead patients [(340.7 ± 108.2) μmol/L,(98.8 ± 59.1) μmol/L,(60.2 ± 10.6) ％,26.9 ± 7.1 and 19 cases,respectively] (P =0.033,P＝ 0.001,P＝ 0.000,P＝ 0.000 and P =0.003,respectively).There was no significant difference of ICGR15 among four types of liver failure.A positive correlation was observed between ICGR15 and MELD score (r=0.289,P=0.009).The ICGR15-MELD model was created by subjecting ICGR15 and MELD scores to Logistic regression analysis.The following ICGR15-MELD model,Logit (P) =0.105 × ICGR15 + 0.178 × MELD score-9.734,was constructed by Logistic regression analysis.The area under the receiver operating characteristic (ROC) curve was 0.860 and the cut offpoint of 0.3 had sensitivity of 85.40％ and specificity of 74.40％.The area under the curve of the ICGR15-MELD model was significantly higher than those of ICGR15 (0.791),MELD score (0.770) and KCH criteria (0.655).Conclusions ICGR15 and MELD scores perform better than the KCH criteria in predicting the prognosis of liver failure.The ICGR15-MELD model is superior to ICGR15,MELD score,and KCH in predicting the short term prognosis of patients with liver failure.

Objective To compare the predicting values for Prognosis among Global Risk Classification (GRS),Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) score,the European System for Cardiac Operative Risk Evaluation (EuroSCORE) in patients who received stenting because of unprotected left main coronary artery (ULMCA) lesion.Methods Totally 105 successive elderly patients with ULMCA lesion who received stenting were divided into 2 groups:with and without main adverse cardiac events (MACE).The clinical and angiographic characteristics were analyzed and then compared among GRC,SYNTAX score and EuroSCORE.Results As compared with none MACE group,MACE group had higher EuroSCORE score (2.0±2.3 vs.6.5±2.9,t=8.18,P=0.002),and more trivessel disease and left main bifurcation lesion (x2 =8.96,6.96,P =0.011,P =0.008).High risk GRC showed more MACE than medium or low risk GRC [55.9％ (19/34) vs.20.5％(9/44),7.4％ (2/27),x2 =19.77,P=0.001].AUC(95％CI )of GRC,SYNTAX score and EuroSCORE were [0.821 (0.730-0.912),0.586(0.462-0.709) and 0.631 (0506-0.757)],respectively.Compared with SYNTAX score and EuroSCORE,GRC was superior in the MACE predicting value (Z=3.29,2.63,P＜0.01 or P＜0.05).

In April 2022,an epidemic occurred in Gongshu District,Hangzhou,where Zhejiang Cancer Hospital is loca-ted.And the hospital was confronted with the most extensive,the most unusual and the most urgent public health emergency crisis since its establishment.Taking patients as the core and proceeding from the public perspective,an authoritative voice of a hospital was conveyed in a timely and accurate manner,which demonstrated the hospital's resolution and executive power in the crisis.Based on Malcolm Gladwell's"tipping point"theory,the paper reveals the situation of online public opinion caused by the sudden epidemic and its response,discusses the hospital's communication practices in handling public health emergencies and provides hospitals with practical reference for brand promotion and operation.

OBJECTIVETo summarise and analyse the experience and methods of managing the perioperative respiratory problems in patients with tumor of trachea or carina surgically treated during the last decade, and the ways of preventing severe postoperative respiratory complications in the future.

METHODSThirty-eight patients with tumor of trachea or carina surgically treated from 1991 to 2000 by different modes of tracheobronchial plastic surgery were retrospectively studied to summarise and analyse the changes in preoperative pulmonary function, postoperative complications and the management of perioperative respiratory problems.

RESULTSOut of 38 patients, 29 (76.3%) gave abnormal results to preoperative pulmonary function tests. 55.3% (21/38) of the whole series developed 45 postoperative complications with respiratory complications as the major one (80.0%). Seventeen patients who had undergone carinal pneumonectomy or carinal resection plus reconstruction gave far more complications (28 complications) than the remaining 21 patients treated by other modes of surgery (17 complications). Four patients died of postoperative complications with a mortality rate of 10.5%.

CONCLUSIONPatients treated with carinal pneumonectomy or carinal resection plus reconstruction give much more complications than patients treated by any other modes of large airway surgery. Fiberoptic bronchoscopic (FOB) guided intubation, precise surgical treatment, postoperative mechanical ventilation support, use of effective antibiotics and sufficient nutritional support are important for a successful management of these patients.

OBJECTIVE To detect potential mutations of the EXT1 and EXT2 genes in a pedigree affected with hereditary multiple exostosis (HME). METHODS For a four-generation family with 7 affected individuals from 17 family members,genomic DNA was extracted from peripheral venous blood samples. All exons of the EXT1 and EXT2 genes were screened for potential mutation by PCR and Sanger sequencing. RESULTS A novel heterozygous frameshift mutation c.1202delT (p.I401Tfs*2)was found in exon 4 of the EXT1 gene in the proband and the other 6 affected individuals. The same mutation was not detected among the healthy members from the family. The mutation has given rise a truncated EXT1 protein with loss of 345 amino acids. CONCLUSION A novel frameshift mutation of the EXT1 gene has been identified in a pedigree affected with HME, which has enriched the mutational spectrum of the EXT1 gene and may facilitate genetic counseling and prenatal diagnosis for the family.

OBJECTIVETo analyze a child with facial abnormalities with combined cytogenetic and molecular techniques and delineate its clinical phenotype.

METHODSNeuropsychological profile of the child was analyzed. Color Doppler, CT and MRI were used for detecting the nodules in the body. Conventional peripheral blood karyotypes of the child and his parents were analyzed with G-banding. Array-comparative genomic hybridization (aCGH) was performed to detect minor structural chromosomal abnormalities.

RESULTSThe child had mental retardation, maxillofacial dysmorphism on the right side, and irregular solid nodules on the back. The karyotypes of the child and his parents were all normal, while aCGH has identified a de novo constitutive 1.2 Mb deletion at 17q11.2 in the child. The aCGH results of his parents were normal.

CONCLUSIONThe de novo 17q11.2 microdeletion probably underlies the facial abnormalities and neurofibromatosis in the patient.

OBJECTIVETo summarize surgical treatment of lung cancer patients with poor pulmonary function.

METHODSFrom 1991 to 1999, 181 lung cancer patients with poor pulmonary function underwent operation. The correlation between the results of preoperative pulmonary functional tests and the postoperative cardiopulmonary complications was analyzed by Chi-square test (chi(2)).

RESULTSIn 181 patients, pneumonectomy was done in 43, lobectomy in 118, partial lung resection in 16 and exploration in 4. The postoperative complication and mortality rates of the resection group were 42.3% (75/177) and 7.9% (14/177). The cardiopulmonary complication rates were 25.6%, 48.3%, 31.3% in pneumonectomy, lobectomy and partial lung resection. The morbidity and mortality rates of 8 patients who received preoperative chemotherapy and/or radiotherapy were 75.0% and 37.5%. The morbidity and mortality rates of 12 patients who had had a previous history of thoracotomy were 66.7% and 33.3%. In the present series, the 1-, 3- and 5-year survival rates were 71.1%, 42.2% and 31.1%. The 5-year survival rates of patients with stage I, II and III lesions were 55.0%, 25.0% and 0.

CONCLUSIONPreoperative spirometry is an important evaluation test for lung cancer patients with poor pulmonary function. It should be evaluated in combination with other pulmonary function tests such as CO(2) diffusion and cardiopulmonary excise tests, etc whenever possible. Patients with a history of thoracotomy, chemotherapy and radiotherapy should be carefully evaluated before operation to avoid high morbidity and mortality. Stage I and II lung cancer patients with poor pulmonary function can undergo operation if they have been well managed preoperatively and well taken care of with nursing care perioperatively.

OBJECTIVE: To explore the genetic basis for a fetus suspected for congenital nephrotic syndrome of Finland (CNF). METHODS: Genomic DNA was extracted from peripheral and umbilical cord blood samples derived from both parents and the fetus. Potential variants were detected by using next-generation sequencing. Suspected variants were confirmed by Sanger sequencing. RESULTS: The fetus was found to carry compound heterozygous variants c.1440+1G>A and c.925G>T of the NPHS1 gene, which were respectively inherited from its mother and father. CONCLUSION Identification of the compound heterozygous NPHS1 variants has enabled diagnosis of CNF in the fetus and genetic counseling for the affected family.

OBJECTIVE: To explore the genetic basis for a pedigree affected with Bartter's syndrome (BS). METHODS: Panel-based next-generation sequencing (NGS) was carried out to detect mutation in BS-related genes SLC12A1, KCNJ1, BSND and CLCNKB. Sanger sequencing of MAGED2 gene and chromosomal microarray analysis (CMA) were also performed on the patient. Suspected mutation was validated in her family members. RESULTS: No pathogenic mutation was detected by NGS, while a 0.152 Mb microdeletion at Xp11.21 (54 834 585-54 986 301) was found in the male fetus, which removed the entire coding region of the MAGED2 gene. His mother was a heterozygous carrier of the deletion. His father and sister did not carry the same deletion. CONCLUSION The loss of the MAGED2 gene may underlie the BS in this pedigree.
