ObjectiveTo investigate the effects of budesonide inhaled on the levels of interleukin-8 (IL-8), C-reactive protein (CRP) and procalcitonin (PCT) in bronchoalveolar lavage fluid (BALF) of patients with AECOPD treated by using inhalation of budesonide in different doses or by using injection of dexamethasone. MethodsNinety AECOPD patients with mechanical ventilation in ICU ward were enrolled from Jan. 2008 through Sep. 2010. All patients were selected in this study as per the criteria of AECOPD set by the Chinese Medical Association. Ninety AECOPD patients treated with routine therapy were randomly (random number) divided into 3 groups. The patients of group A were given budesonide 2 mg inhaled 1 time/d. The patients of group B was given budesonide 4 mg inhaled 1 time/d. The patients of group C had dexamethasone 2. 5 mg injected 1 time/12h. The changes of IL-8, PCT and CRP in both BALF and serum were respectively detected in three groups at the beginning of treatment, and 3 days and 7days after treatment. The detected data of variables were analyzed by SPSS 13.0 package. ResultsThe level of IL-8 in BALF declined in 3days and 7days after treatment, and the magnitude of decrease in the following order:Group B ( budesonide 4mg/d) ＞ Group A ( budesonide 2 mg/d) ＞ Group C ( intravenous dexamethasone)with significant differences among them ( P ＜ 0. 05 ). The decrease in IL-8 in serum showed the similar trend, but there were no statistical differences among them. The CRP and PCT in both BALF and serum had no significant changes. There was a correlation between the concentration of IL-8 in BALF and the duration of mechanical ventilation.Conclusions The treatment with the inhalation of budesonide could more significantly reduced the IL-8 level in BALF compared with intravenous dexamethasone, whereas the CRP and PCT were not changed. The dynamic changes of IL-8 in BALF might be used as an indicator of prognosis in AECOPD patients with mechanical ventilation.

Objective To investigate the clinical efficacy of combination therapy of ambroxol with vibration? expectoration machine on ventilator-associated pneumonia Methods A total of 96 patients from the Department of Critical Care Medicine were selected and randomly divided into 3 groups:control group,ambroxol group and ammonia ambroxol + vibration expectoration machine group (n=32,each).The ventilator-associated pneumonia (VAP) was randomly divided into three groups (n =32,each).All patients were treated with conventional therapy including anti-inflammatory,suction,airway humidification,nutritional support.On this basis,ambroxol group was given ambroxol 30 mg in 100 ml normal saline,intravenously dripped 3 times a day.On the basis of treatment in the ambroxol group,ammonia ambroxol + expectoration machine were given G5 vibration expectoration machine to expectorate sputum 2 times every other day.Results There were significant differences in acute physiology and chronic health evaluation (APACHE Ⅱ),PaO2/FiO2,respiratory rate (RR),heart rate (HR) before versus after the treatment of the three groups (F =5.736,9.432,6.361,5.862,respectively,all P＜0.05).After treatment in the three groups,APACHE Ⅱ,PaO2/FiO2,RR and HR showed statistically significant differences inter-group among three groups (F=4.674,8.665,7.351,6.562,respectively,all P＜0.05).Clinical effective rates of the three groups were 71.9％,84.4％,93.8％ respectively,and showed statistically significant differences inter-group among three groups (all P＜0.05).Conclusions Combination therapy of ambroxol and vibration expectoration machine shows significant effects on VAP,and it is better than ambroxol alone.

Objective To investigate the effects of xuanzhi analgesic tablets on plasma levels of 6-keto-prostaglandin Flα(6-K-PGFlα) and thromboxane B2(TXB2) in rats with acute blood stasis. Methods Sixty SD rats were divided into six groups randomly, namely normal control, model control, positive control, xuanzhi analgesic tablets at 1. 36, 2. 72, and 5. 44 g·kg-1 groups. The rat model of blood stasis syndrome was caused by subcutaneous injection of adrenaline incorporated with ice-bathing. The effects of xuanzhi analgesic tablet on 6-K-PGFlαand TXB2 were observed. Results Compared with the normal control,plasma level of 6-K-PGFlα was significantly reduced(P<0. 01) and that of TXB2 in the model control was evidently increased(P<0. 01). Three dosages of xuanzhi analgesic tablets significantly raised 6-K-PGFlαlevel(P<0. 05)and lowered TXB2 level (P<0. 05). Conclusion Xuanzhi analgesic tablets significantly adjust plasma levels of 6-K-PGFlαand TXB2in rats with acute blood stasis. Xuanzhi analgesic tablets can coreect the imbalance between PGI2 and TXA2 through increasing 6-K-PGFlαand desearing TXB2 levels.

Objective To investigate the histogenesis,clinicopathological features and biological behavior of goblet cell carcinoid (GCC) of the appendix. Methods 3 cases of GCC of the appendix were studied by light microscopy and immunohistochemistry. Results 3 cases all occured in men. Microscopically: the tumor was composed of goblet cells containing mucin-filled with basal round to crescentic nuclei without atypia.These tumor cells were arranged in single forms,nests or acinus with no central lumen. 1 case was composed of simple goblet cells and typical carcinoid cells were seen in other 2 cases arranged in trabeculae and tubule.There was transition between goblet cells with tubelar and crypt epithelium.Immunohistochemical staining revealed that goblet cells were positively reacted with CgA, Syn, CEA, CK and p53 in 1 case. Conclusions Goblet cell carcinoid of the appendix arise from a pluripotent cell with divergent neuroendocrine and mucinous differentiation .It is a subtype of carcinoids of the appendix.The diagnosis mainly bases on its morphologic changes and immunohistochemical findings. The unpredictable behavior of this tumor is probably related to its component and the degree of infiltration.

Objective:To investigate the expression status of Sonic Hedgehog signaling genes and molecules in human hepatocellular carcinomas(HCC),and to explore the relationship between these genes and clinical prognosis.Methods:HCC tissue and adjacent normal tissue from 29 HCC patients were assayed for the expression of hedgehog signaling genes by reverse transcription-polymerase chain reaction chain reaction(RT-PCR) techniques and for the expression of hedgehog signaling molecules by immunohistochemistry.The expressions of Shh,Ptch,Smoh,Gli-1 mRNA were assayed as well as Shh,Ptch proteins in 29 cases of HCC and in 29 liver tissues adjacent to the tumor.Results:Expression of Shh mRNA was detectable in about 51% of HCCs examined.Consistent with this,hedgehog target genes Ptch,Smoh and Gli-1 mRNA were expressed in over 68%,48% and 62% of the tumors,respectively,and the expressions of Shh and Ptch proteins in HCC tumor tissues correlated with those of Shh and Ptch mRNA in tumor tissues(P=0.041 and P=0.035).This suggested that the hedgehog pathway was frequently activated in HCCs.The simultaneous expression of Gli-1 in HCC and liver tissues adjacent to the tumor had significantly relationship with poor prognosis.Conclusion:Hedgehog signaling activation is an important event for development of human HCCs.It also suggests that markers for hedgehog signaling activation may be useful for the determination of prognosis.

Background and purpose:Nab-paclitaxel (Abraxane) is an albumin-bound form of paclitaxel that utilizes the natural properties of albumin to improve paclitaxel delivery to the tumor. It has recently been approved for treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within short time after adjuvant chemotherapy. The purpose of this study was to evaluate the efifcacy and safety of albumin-bound paclitaxel in patients with aggressive and refractory metastatic breast cancer (MBC).Methods:A total of 58 patients with MBC were enrolled into this study from Jul. 2009 to Jan. 2014. All patients received albumin-bound paclitaxel-based chemotherapy. The adverse reactions were evaluated every cycle, and the short-term response was evaluated every two cycles. The patients were followed-up, and the survival was analyzed.Results:58 patients with refractory MBC were evaluable for response, 67.2% of patients received multiple line (≥3 lines) chemotherapy, 32.8% of patients with first and second line of chemotherapy were involved metastasis within one year after adjuvant chemotherapy, 84.5% of patients with visceral metastasis and 93.1% with prior taxane treatment. The objective response rate (ORR) was 13.8%, and disease control rate (DCR) was 60.3%, the median progression free survival (PFS) was 4.0 months, and the overall survival (OS) was 10.1 months. For 23 patients with triple negative breast cancer, ORR was 13.0% and DCR was 56.5%, the median PFS was 4.1 months, and OS was 6.6 months. The main toxicity was myelosuppression (grades 3 and 4 neutropenia, anemia and thombocytopenia were seen in 34.5%, 12.1% and 6.9% of patients, respectively), gastrointestinal reactions, sensory neuropathy, myodynia/arthragia, fatigue, alopecia and so on.Conclusion:The albumin-bound paclitaxel-based chemotherapy can be used in aggressive and refractory MBC. It also showed antitumor activity in taxanes-resistance patients and triple negative patients with good safety and tolerance.

Objective To investigate the status on children of 3-14 years old who suffered from cerebral palsy in Liaoning province. Methods One thousand three hundred and twenty-three cases of children with cerebral palsy of 3-14 years old who received rehabilitation in city hospital, county hospital and community hospital were investigated from January 2013 to October 2016 in 14 cities in Liaoning Province. The proportion of cerebral palsy children in 3-4 years old, 4-5 years old, 8-9 years old, 5-6 years old , 6-7 years old and 7-8 years old was about 10%, and in the other age the proportion was about 7%. The proportion of men and women generally was 4:1;neonatal convulsion (252 cases, 19%), premature delivery (230 cases , 17.3%) and low birth weight infant (187 cases, 14.1%) were main risk factors and accounted for more than 10%. Spastic type cerebral palsy accounted for the highest proportion (54.35%, 719 cases)and ataxia cerebral palsy accounted for the lowest proportion (2.95%). In complications , lower intelligence accounted for the highest proportion (50.34%, 666 cases), followed by the language barrier (43.99% , 582 cases), and the other complications accounted for less than 10%.;gross motor function classification in most studied children was stageⅡ(35%) and stageⅢ(32.50%); 6.95% patients could go to school, and 84.96% patients had health insurance. Patients coming from city accounted for 69.01%, and patients coming from rural area accounted for 30.99%. Mothers′ education below primary school was 4.16% . 36.05% children received rehabilitation in comprehensive hospital, 60.09%in children′s hospital and 3.85%in maternal and child health hospital. Conclusions Spastic cerebral palsy is the main type of children with cerebral palsy in Liaoning.High risk factors include neonatal convulsions, premature birth and low birth weight infants. Most patients complicate with low intelligence and language barriers.This paper can be used as the basis of further research on prevention and treatment

OBJECTIVETo explore the linkage relationship between specific genetic markers and arrhythmogenic right ventricular cardiomyopathy (ARVC) in Chinese pedigrees.

METHODSThe microsatellite genetic markers D2S152, D14S252, and D10S1664 were studied for their linkages to ARVC in five Chinese ARVC pedigrees and a normal population of 121 Chinese individuals. Genomic DNA of the pedigrees and normal population was amplified using PCR techniques. Denaturing polyacrylamide sequencing gel (4%) electrophoresis was used to detect microsatellite repeat polymorphisms. Gels were silver-stained. A classical linkage analysis program was used assuming models of autosomal dominance and recession.

RESULTSThe logarithm of the odds (LOD) scores of D2S152 with ARVC in LW, WD, DS, LC and TY pedigrees were 2.174, -0.589, -infinity, - (indicating that linkage is not supported in this mode), and -infinity respectively in autosomal dominant model (recombination fraction = 0.000 respectively)and were -infinity, -infinity, -infinity, -infinity, and 0.182 respectively in the autosomal recessive model. The LOD scores of D14S252 with ARVC in LW, WD, DS, LC and TY pedigrees were -, -, -infinity, -, and 0 respectively in autosomal dominant model, and were -infinity, -0.812, -infinity, -infinity, and 0.087 respectively in autosomal recessive model. The LOD scores of D2S152 with ARVC in LW, WD, DS, LC and TY pedigrees were -, -0.539, -, and 0.602 respectively in autosomal dominant model and were -, -infinity, -infinity, -infinity, and - infinity respectively in autosomal recessive model.

CONCLUSIONSThe LOD score for D2S152 in the LW pedigree was 2.174, indicating that the chance of linkage is about 150:1. This suggests that there is a possible ARVC-related gene near this marker. There were no clear linkage relationships between ARVC and D10S1664 and D14S252 in this family, and no linkages between ARVC and any of the three genetic markers in the other four families. These results also suggest that there is genetic heterogeneity in LW and in the other pedigrees.
