With the development of the thoracic surgery, clinicians are paying more and more attention to acute lung injury (ALI) following thoracic surgical procedures. Many factors may cause ALI during the operation. This review updates recent researches on the pathogenesis and treatment strategies of the ALI in thoracic surgical procedures.

Objective To explore the clinic value of chromosome karyotype analysis of amniotic fluid cells in prenatal diagnosis . Methods 1 466 cases of pregnant women who had the prenatal diagnosis indexes were selected ,and their amniotic fluid specimens were collected through amniocentesis guiding by type‐B ultrasonic around the 16th to 24th week .Amniotic fluid cells were gained after a successful cell culture .G banding was used for the karyotype analysis of amniotic fluid cells .Results The one‐time success rate of cultivation for amniotic fluid cells was 99 .8% .In 1 466 cases of pregnant women ,there were 16 cases of abnormal karyotype polymorphism (including 12 cases of trisomy 21 ,1 case of trisomy 18 ,and 3 cases of Chromosome abnormalities) and 3 cases of chromosomal polymorphism .Conclusion The chromosome karyotype analysis of amniotic fluid cell is still an irreplaceable test in prenatal diagnosis .

Objective To explore the therapeutic effect of Yupingfeng powder in secondary immunodeficiency caused by simple nephrotic syndrome(SNS) in children.Methods Seventy-eight cases of SNS patients were divided into 2 groups randomly.One was control group which were treated with immunosuppressant only.The other group was Yupingfeng powder group which were treated with both immunosuppressant and Yupingfeng powder.The morbidity of infection,the relapse rate of SNS,and serum immunoglobulin IgA and IgG and the T-lymphocytes subtype were detected before and after treatment in two groups.Results The morbidity with infection was 55.3% in Yupingfeng powder group,which shows a remarkable decrease compared with control group(85%).The relapse rate of SNS was 39.5% in Yupingfeng powder group which was much lower than that in control group(67.5%).The level of serum IgA and IgG before treatment were(3.88?1.22) g/L and(0.83?0.14) g/L and rose up to(10.06?1.89) g/L and(1.38?0.10) g/L after treatment in Yupingfeng powder group.Whereas the control group with(6.23?1.55) g/L and(0.85?0.13) g/L was remarkably lower than those in Yupingfeng powder group.CD4+,CD8+ and the ratio of CD4+/CD8+ were(37.91?3.89)%,(30.69?3.08)% and(1.24?0.49)% respectively before treatment.They rose up to(42.38?4.89)%,(26.01?2.20)% and(1.63?0.41)% respectively in Yupingfeng powder group,while those in control group were(39.87?3.91)%,(29.76?3.55)% and(1.34?0.24)% respectively after treatment.Conclusion It is feasible to treat the Yupingfeng powder to cure the of secondary immunodeficiency caused by SNS in children.

Objective To investigate the influence of Simiao pill intervention on the life quality of patients with chronic pelvic inflammatory disease( CPID) . Methods Eighty-five cases of damp heat and blood stasis type of CPID were randomly divided into two groups:the treatment group( n=43) was treated with Simiao pill decoction combined with other Chinese herbs;the control group(n=42)was treated with Fuke Qianjin capsules.Three months after the treatment, clinical efficacy was evaluated and life quality was assessed by WHOQOL-BREF. Results The total effective rate was 90. 70% in the treatment group and 71.43% in the control group(P<0.05).Before the treatment, score of each dimension of WHOQOL-BREF in both groups was not significantly different(P>0.05).After the treatment, score of each dimension of WHOQOL-BREF in both groups were increased, and the total score was(104.21±6.67)in the treatment group and(89.60±7.31)in the control group(P<0.05). Conclusion Simiao pill decoction combined with other Chinese herbs can effectively treat damp heat and blood stasis type of CPID and improve the life quality of the patients.

0.05). ②Plasma endothelin in the two groups was remarkably decreased after treatment(P0.05).③ NO in the two groups was significantly increased after treatment(P0.05). Conclusion TFL can reduce blood pressure and improve endothelial cell function.

Objective To explore ways for expanding the now-limited coagulation volume of percutaneous microwave coagulation therapy(PMCT) in liver in order to enhance the complete necrosis rate of large hepatic tumors with obviously fewer punctures. Methods Fresh pig livers in vitro and rabbit, pig livers in vivo with and without blood supply were coagulated using the self-designed HM-WIA microwave coagulator to make clear antenna length, microwave power, coagulation time and blood flow influence the microwave volume(MCV).Results The device enlarged the MCV by 3 times using single electrode with an antenna of 36 mm in length along with microwave power of 45-55 W and coagulation time of 15-19 min,the short axis of the coagulation area was 5.6 cm in vitro, 5.3 cm in vivo with no blood supply.The antenna 36 mm in length was proved the best in keeping the finest coagulation shape.The MCV was 2.8 times as large without blood supply as with it (P

OBJECTIVE:To investigate the effect of liposome formulation in promoting hepatocytes' uptake of tenofovir and cytotoxic effect. METHODS: The tenofovir cationic liposomes were prepared by tert-butyl lyophilization, and its encapsulation efficiency and physico-chemical property were determined. Using human hepatic carcinoma cells SMMC-7721 as a model to investigate the effect of liposome formulation in promoting hepatocytes' uptake of tenofovir. MTT assays were used to examine the toxicity of tenofovir cationic liposomes in different conditions. RESULTS: The prepared tenofovir cationic liposomes had an encapsulation efficiency of (88.3?1.6)%, a size distribution of (278.4?67.6)nm and a Zeta potential of (31?5)mV. The results showed that the liposome formulations containing galactose and PEG modifying lipids resulted in significantly higher and prolonged drug accumulation inside cells as compared with free drugs. The cell survival rates were above 80% when the tenofovir liposome was at a concentration of 7.5?g?mL-1 and lipids at a concentration of 30?g?mL-1, and little toxicity was noted. CONCLUSION: The prepared cationic liposome can greatly enhance hepatocytes' uptake and protection of tenofovir, which is expected to become a highly effective drug delivery system of antiviral drugs such as tenofovir etc.

The object of medical research is human life,thus the understanding level of human being determines medical mode and the development of medical science.The origin of Marx's theory on human being is the realistic human,which provides methodological basis for reflecting on the biomedical faults from a logical perspective.Marx held that technology is the objectization of the essential power of human being,while technology under the context of capitalist production relations has been turned into certain means to control workers.Tend of dissimilation also arises in some modern medical fields,thus serious reflection and criticism are in great need.The overall development of human being is the core content in Marx's theory on human being.Since modern medicine is during the transition from bio-medical model to bio-psycho-social medial model,the new medical model calls for an overall development of main body in all aspects including qualification,ability,and social relations,etc.

Background and purpose:Reduced peripheral blood platelet count is a common toxicity in patients with hematological malignancy after chemotherapy.The purpose of this study was to observe the eff icacy and safety of recombinant human thrombopoietin(rhTPO)in the treatment of thrombocytopenia induced by chemotherapy.Methods:A total of 25 patients with solid tumor,who developed thrombocytopenia induced by chemotherapy(PLT≤70?109/L) after the f irst cycle of chemotherapy(control group),was studied by self-cross control.6-24 h after the second cycle of chemotherapy(treatment group) with identical scheme of the f irst cycle chemotherapy,they were given subcutaneous injection of rhTPO 15 000 U/d for 7 to 14 consecutive days or until platelet count ≥100?109/L or the increasing count ≥50?109/L.Results:The mean platelet count of the patients after rhTPO treatment was higher at different time points of the treatment group than that of the control group.The minimal PLT count of the treatment group and the control group after chemotherapy were(80.3?39.30)?109/L and(34.7?21.2)?109/L(P0.05).The time of PLT count to recover was found to be more than 75?109/L and 100?109/L in treatment group after chemotherapy was(9.8?4.2)d and(12.8?3.6)d,compared to(19.1?4.5)d and(24.3?1.4)d(P
