Objective To observe the effect of Fufei Gushen Decoction on the BODE index, an index for body mass index(BMI), airflow obstruction, dyspnea, and exercise capacity, in severe and extremely severe chronic obstructive pulmonary disease (COPD) patients with lung-kidney deficiency interweaved with phlegm and blood stasis at stable stage. Methods Eighty qualified COPD patients were randomly divided into treatment group and control group, 40 cases in each group. Both groups were given inhalation of Seretide (Salmeterol Xinafoate and Fluticasone Propionate Powder for inhalation) , and the treatment group was given oral use of Fufei Gushen Decoction additionally. The treatment for the two groups lasted for 3 months. Before and after treatment, BMI, the percentage of forced expiratory volume in one second of the predicted value (FEV1%) , dyspnea index of modified British Medical Research Council (MMRC), and exercise performance index of 6-min walking test (6MWT) in the two groups were observed. Results (1) After treatment, FEV1%, MMRC dyspnea index, 6MWT scores and BODE index overall scores of severe and extremely severe patients in the treatment group were much improved(P < 0.05 compared with those before treatment ), but BMI was not much improved(P > 0.05). MMRC dyspnea index, 6MWT scores and BODE index overall scores of severe and extremely severe patients inthe control group were much improved (P<0.05 compared with those before treatment) , b ut the improvement of FEV1% and BMI was not obvious(P > 0.05).(2) Except for BMI, the parameters of FEV1%, MMRC dyspnea index, 6MWT scores and BODE index overall scores of the treatment group were much improved as compared with those of the control group after treatment(P < 0.05). Conclusion Fufei Gushen Decoction combined with inhalation of Seretide exerts certain effects on decreasing the BODE index scores, relieving symptoms, and improving pulmonary function, exercise performance and the quality of life of COPD patients with lung-kidney deficiency interweaved with phlegm and blood stasis at stable stage.

Objective: To investigate the causes and management of enteral feeding intolerance in patients with severe acute pancreatitis (SAP). Methods: The clinical data were retrospectively analyzed of 128 SAP patients who underwent enteral feeding treatment during the period from January 2006 to January 2008. Results: The rate of enteral feeding intolerance was significantly higher in the group of patients who didn' t use Flocare 800 pump, single-use enteral feeding tube and heater (10/50 or 20.0%) than that in the group of patients who used Flocare 800 pump, single-use enteral feeding tube and heater (5/78 or 6.4%). Conclusion: The possible risk factors of enteral feeding intolerance may be transfusional speed, temperature and concentration of nutritional fluid. Severity of acute pancreatitis is another important factor. Intestinal dysfunction should be noticed during the enteral nutritional support.

Objective To investigate the variation of procalcitonin(PCT) in blood and tissue level of acute pancreatitis rats and probe its significant. Methods One hundred and two male Wistar rats were randomly divided into control group ( n = 6 ), lipopolysaccharide group ( LPS, n = 24 ), acute edematous pancreatitis (AEP) group ( n = 24), acute necrotizing pancreatitis (ANP) group ( n = 24), AN P + LPS group ( n = 24). Subcutaneous injection of cerulein was used for AEP induction, while ANP model was induced by retrograde injection of sodium taurocholate into the biliary and pancreatic duct. The rats were sacrificed at 3,6, 18 and 24 hours after model induction. Pancreatic tissue was harvested and the pathological scores were assessed. Levels of PCT in serum, liver, lung, spleen, pancreas, small intestine, large intestine tissue was harvested and tissue levels of PCT were determined. Results AEP and ANP models were established successfully. At 6 h, the serum levels of PCT in control group, LPS group, AEP group, ANP group and ANP +LPS group were (0.0144 ±0.0082) ng/ml, (0. 1722 ±0.0449) ng/ml,(0.4751 ±0.0572) ng/ml, (0.7070 ±0. 1040) ng/ml and ( 1. 1960 ±0.8644) ng/ml, respectively; and the difference was statistically significant (P < 0.05 ). PCT could be detected in liver, lung, spleen, pancreas, small intestine and large intestine tissue of normal rats. PCT levels in liver and pancreas of ANP group were not statistically different, but the PCT levels in lung, spleen, and large intestine tissue significantly decreased, and the corresponding values were (5.63 ±0.62) ng/ml vs. (6.85 ±0.46) mg/ml, (4.73 ±1.27) mg/ml vs. (6.88 ±0.37) ng/ml, (1.08 ±0.52) ng/ml vs. (4.12 ± 1.02) ng/ml (P <0.01 ). However, the PCT levels in small intestine significantly increased, which were (2.51 ±0.90) ng/ml vs (0.98 ±0. 12) ng/ml (P<0. 01). Conclusions Serum PCT level was associated with the severity of AP and infection; the changes of PCT levels in different tissues may be related with the changes of organ's function.

Objective To explore the microRNA-16 (miR-16) and nuclear-transcription factor-κB1 (NF-κB1) expressions in human brain gliomas and their correlations with cell invasion and growth of malignant gliomas SHG44,U87 and U373.Methods (1) Twenty-nine cases of human glioma tissue samples and 6 normal brain tissues,collected in our hospital from January 2000 to January 2011,were chosen in our study; quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the expressions ofmiR-16 and NF-κB1 in these tissues.(2) In vitro cultured U87,U373 and SHG44 cells were divided into blank-control group,nonsense sequence transfected group and miR-16 mimics transfected group; 48 h after the transfection,qRT-PCR was used to detect the expressions of miR-16 and NF-κB1; tmnswell assay was used to observe the cell invasion capability; 72 h after the transfection,Western blotting was employed to detect the protein expressions of NF-κB1,matrix metallopeptidase 9 (MMP-9) and MMP-2.(3) Luciferase reporter assay was used to detect the target regulating role of miR-16 in NF-κB1 gene.(4) U87 cells were used as negative control group,and U87 cells carried stably expressed miR-16 gene were implanted into intracranial and subcutaneous nude mice (U87-miR-16 group); immunofluorescence was used to detect the MMP-9 expression,and immunohistochemical staining was used to detect the protein expressions of Ki-67,NF-κ B1 and MMP-9; subcutaneous tumor volume was measured and the growth curve was drawn.Results (1) The qPCR results showed that the expression of miR-16 in human brain glioma tissues was significantly lower than that in normal brain tissues; and gradually decreased miR-16 expressions were noted in gliomas of graded Ⅰ,Ⅱ,Ⅲ and Ⅳ (P＜0.05); NF-κB1 expression in human brain glioma tissues was significantly higher than that in normal brain tissues; and gradually increased NF-κB1 expressions were noted in gliomas of graded Ⅰ,Ⅱ,Ⅲ and Ⅳ (P＜0.05).(2) As compared with those in the blank-control group and nonsense sequence transfected group,miR-16 mimics transfected group had significantly increased miR-16 expression,decreased NF-κB1 mRNA expression,decreased invasiveness,and decreased protein expressions of NF-κB1 and MMP-9 (P＜0.05).(3) Luciferase reporter assay showed that the fluorescence normalized ratio in the pMIR-NF-κB1 group was signfcaintly higher than that in the pMIR-NF-κB1+pre-miR-16 group (P＜0.05).(4) As compared with the negative control group,the U87-miR-16 group on the 24-42 d of implantation had significantly smaller volume of tumors (P＜0.05),and lower MMP9 expression,and NF-κB1,MMP-9 and Ki-67 expressions (the proliferation index of Ki-67:13.91％ and 32.98％).Conclusion MiR-16 inhibits glioma cell invasion and growth through down-mgulating NF-κB1 and MMP-9 expressions.

Objective:To explore the influences of times of venous thromboembolism (VTE) drug prophylaxis in formation of deep vein thrombosis (DVT) in patients with severe craniocerebral injury after surgical treatment.Methods:Ninety patients with severe craniocerebral injury, admitted to our hospital from February 2021 to December 2021, were chosen in our study; they were divided into early group ( n=47, less than 48 h from the time of admission) and late group ( n=43, more than 48 h from the time of admission) according to the times of initiation for VTE drug prophylaxis (low molecular weight heparin calcium injection [LMWH] 100 IU/Kg was injected subcutaneously once a d). One week after injection, the DVT formation in the lower limbs, intracranial rebleeding, gastrointestinal bleeding and death were compared in the two groups. Results:The times of initiation for drug prophylaxis in the early group and late group were (28.91±4.50) h and (71.56±8.89) h. The DVT formation in the early group was significantly lower than that in the late group (12.8% vs. 34.9%, P<0.05). There was no difference in the incidence of intracranial rebleeding, mortality or gastrointestinal bleeding between the two groups ( P>0.05). Conclusion:Early initiation of VTE drug prophylaxis can significantly reduce the incidence of DVT in patients with severe craniocerebral injury after surgical treatment, enjoying high safety.
