A computer-based online search of PubMed database and Chinese Journal Full-text Database was undertaken to identify articles about the monitoring of pulmonary arterial pressure (PAP),mixed venous oxygen saturation (SvO2),and breathing mechanics in the patients undergoing lung transplantation from January 1990 to May 2008 to evaluate their clinical values in maintaining cardiorespiratory function of patients during anesthetic stage. PAP,cardiac output and SvO2 are key parameters of monitoring during the diseased lung resection and donor lung transplantation; breathing mechanics and SvO2 are key parameters of monitoring after lung ventilation. The former are reliable indicator to predict lung transplantation reaction and pulmonary edema and the latter can guide regulation of positive end expiratory pressure and when to remove extracorporeal membrane oxygenator. A combination of hemodynamics (PAP,pulmonary capillary wedge pressure,cardiac output,and central venous pressure),breathing mechanics and SvO2 consists an overall monitoring of heart and lung function. By Meta-analysis,these indicators can guide the regulation and protection of heart and lung function in patients undergoing lung transplantation and other severe patients during the anesthesia period.

The tumor stem cell has attracted more and more attentions in recent years,which is involved in a possibili- ty that the knowledge on the tumor stem cell would be a novel base for the developing of research fields in the tumor pre- vent,diagnose and therapy.However,the basic knowledge system on tumor stem cell has not formed as an enough re- search about it has not been done.In this commentary,the author presents his understanding on several biological issues of tumor stem cells,and some controversy in this field as well.The author also wishes his necessary information would in- duce reader's interesting and future considerations.

Genetically engineered mice is one of the powerful research systems in exploring the gene protein life phenomenon,which is useful in generating the laboratory animal model of human diseases and developing the new drugs. With the development of functional genomics and model organism in life science area, biological medicine research is in need of genetically engineered mice deadly. There are still some problems to be resolved, including death effect, no or low expression and no phenotype. It is essential to improve the basic research related to genetically engineered mice.

Objective: To improve the micro-manipulation of mouse fertilized eggs,promoting its survival rate and productivity in pseudo-pregnant mice. Methods: DNA fragments of definite concentration and size were used for micro-manipulation with conventional and improved methods, then their survival rate of manupulated eggs and productivity of pseudo-pregnant mice were analyzed and compared. Results: With improved methods, the survival rate of eggs increased from 60.3% to 79.5%, the productivity of pseudo-pregnant mice and offspring increased from 35.7% to 56.8% and 10.1% to 14.1% respectively. Conclusion: The improved methods of micro-manipulation can be used in transgenic mouse production.

Aberrant promoter methylation in special genes such as tumor suppressor genes is early eventin carcinogenesis of lung cancer. Aberrant methylation, resulting in corresponding mRNA silence or overexpression , closely relates to carcinogenesis, development, treatment response and prognosis of lung cancer and it may become a potential biomarker. Methylation of special genes may provide evidences for individual treatment of lung cancers.

OBJECTIVE To analyze the bacterial distribution and drug-sensitivity in sputum bacterial culture of the hospitalized patients with respiratory tract infection in the department of respiratory medicine to help reasonably choose the antibiotics and reduce the nosocomial infection rate. METHODS The bacterial infection of all the hospitalized patients with lower respiratory tract infection in the department of respiratory medicine from 2004 to 2005 was analyzed retrospectively and compared with all the patients of the hospital. RESULTS The nosocomial infection rate of the department of respiratory medicine in 2005 was 10.18%,which was higher than the rate of nosocomial infection of the whole hospital(3.09%).The Gram-negative bacteria were the main ones infected through respiratory tract.What should be paid attention to was the comparably higher fungal infection rate in 2005.The main Gram-negative bacteria were dominated by Pseudomonas aeruginosa.The most sensitive drug was piperacillin+ tazobactam in 2004 and aminoglycoside antibiotics in 2005.The Gram-positive bacteria were most sensitive to vancomycin. CONCLUSIONS The nosocomial infection is dominated by lower respiratory tract infection in the department of respiratory medicine.The nosocomial infection rate,dominated by Gram-negative bacteria is high.In order to decrease nosocomial infection rate,cross infection should be avoided,sensitive antibiotics be chosen,body resistance be enhanced and hospital stay be reduced.

Objective:To understand the liability situation of urban public hospitals in Jiangxi.Methods:Qualitative and quantitative analysis,descriptive analysis and comparative analysis were used to analyze the causes and changes of urban public hospitals' debt increase.Results:To meet the increasing demand for health diagnosis and services,debt infrastructure and the purchase of equipment coupled with inadequate financial investment were performed in public hospitals,which resulted in the sustainably increasing of liabilities level in urban public hospitals.Conclusion:Governments at all levels should increase the capital expenditure of hospital construction and equipment investment,strictly control the public hospital debt behavior,the implementation of the reform of public hospitals canceled drug addition,establishing the characteristics of the medical industry personnel salary system and other measures to resolve the synchronous speed of public hospital debt and prompt public hospital debt risk control in the reasonable scope.

Objective To investigate the expression of vascular growth factors including vascular endothelial growth factor(VEGF), basic fibroblast growth factor(bFGF) and platelet-derived growth factor (p-DGF) in placentae of pregnancy-induced hypertension(PIH) patients and their significance. Methods Placental tissues of 15 normal gravidas and 19 PIH women were collected. The expression of vascular growth factors were detected by immunohistochemistry (PAP) combined with the analysis of computer microphotography. Results The average grey value difference (GVD) of VEGF was 61.6?3.7 in moderate and severe PIH group, which was significantly lower than that of the normal control group (71.1?5.8) and mild PIH (70.9?8.9, P

Objective To investigate the effects of patient-controlled intravenous analgesia (PCIA) with lornoxicam and fentanyl on arrhythmia and the expression of platelet membrane glycoproteins in patients with coronary artery disease (CAD) after abdominal surgery.Methods Eighty ASA II or III patients with CAD aged 51-66 yrs weighing 59-68 kg presenting for bdominal surgery participated in this study. CAD was diagnosed by clinical symptoms and ischemic changes on ECG. The patients were premedicated with intramuscular henobarbital 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with fentanyl, droperidol, propofol and vecuronium and maintained with propofol, fentanyl and vecuronium. The patients received PCIA after operation. The PCIA solution contained fentanyl 0.9 mg and droperidol 5 mg in 100 ml of normal saline (N.S. ) in group A ( n - 40) or lomoxicam 56 mg, fentanyl 0.2 mg and dropendol 5 mg in 100 ml N.S. in group B ( n = 40). In group A the loading dose was fentanyl 0.05 mg and in group B lornoxicam 4 mg. PCIA included a background infusion at 2 ml ? h-1 and a bolus of 0.5 ml with a 15 min lock-out. VAS (0 = no pain, 10 = worst pain) was used to measure pain intensity In addition to BP, HR and SpO2 monitoring ECG was continuously monitored with a Holler monitor after operation Blood samples were taken from peripheral vein before and 6h after operation and on the 1st, 2nd, 7th and 8th postoperative days for determination of the expression of CD62p, CD63 and CD41/CD61 on the platelet membrane, platelet count, prothrombin time ( PT) thrombin time (TT) and partial thromboplastin time (PTT) Results The two groups were comparable with respect to sex, age, body weight, severity of CAD, duration of operation and intraoperative blood loss. The patients received no blood transfusion during operation. There was no significant difference in VAS score, platelet count, PT, TT and PIT between the two groups. The incidence of atrial and ventricular premature beat on ECG and the expression of CD41 /CD61 , CD62P and CD63 on the platelet membrane were significandy lower in group B than in group A on the 7th and 8th postoperative days (P
