Hepatocellular carcinoma(HCC) is one of the most common malignant tumors in the world.According to the statistic data of Ministry of Public Health of China in 1995, the annual mortality of HCC was 20.4 per 0.1 million, and had the rise tendency. Surgery is commonly the main modality of HCC combined therapy. The high intensity focused ultrasound (HIFU), as a noninvasive therapy, with the mechanism of transient high temperatures, cavitation and mechanical effects, has been recognized. This review aimes to elucidate the immune changes in HCC after HIFU exposures and the mechanism.

Objective:To investigate the effects of electroacupuncture (EA) on intestinal motility disorder in rats with irritable bowel syndrome (IBS) in order to provide experimental evidence for improving clinical treatment to IBS with EA. Methods: IBS was induced by inserting a balloon into the rectum of male Sprague-Dawley rats from their neonatal age (8th, 21st day after birth) and applying colorectal distention stimulation by inflating air into the balloon. Peristaltic wave (PW) was used to estimate intestinal motility. Rats were divided into 4 groups (n=6): normal group, untreated group, sham EA group and EA group. Acupoints of Zusanli (ST36) and Shangjuxu (ST37) in the hind limbs bilaterally were chosen for EA and sham EA treatment. Trains of dense-sparse frequencies (100 Hz and 2 Hz alternately) and intensity of 1, 2 and 3 mA (10 min for each) were applied for 30 min with each EA treatment while inserting similar needles without electrical stimulation was done as sham EA treatment. PW recorded for 30 min in normal and untreated groups respectively was taken as control values, while PW recorded after EA or sham EA treatment for 30 min was taken as responsive values. Results: Frequency of PW was significantly increased in the untreated group as compared with that in the normal group (P<0.05), and decreased after 30-min EA treatment (P<0.05). There was no significant change in the PW of sham EA group as compared with the control group and before treatment (P>0.05). Conclusion: These results suggest that 1) there is an abnormal increase in intestinal motility indicating an intestinal motility disorder in IBS rats; 2) EA but not sham EA can relieve such intestinal motility disorder.

Background Insulin-like growth factor-1 (IGF-1) participates in the regulation of the biological activity of cells.Researches showed that the serum IGF-1 level is significantly raised in the patients with Graves diseases.Thyroid associated ophthalmopathy (TAO) is one of Graves diseases,and orbital adipose cells are the target cells of thyroid autoantigens.However,whether IGF-1 is associated with TAO is still unclear.Objective This study was to investigate the expressions of IGF-1 in both circulating blood and orbital adipose tissue in TAO patients.Methods A retrospective cohort study was performed.Eighty-six TAO patients were enrolled in West China Hospital of Sichuan University from August 2009 to February 2014.According to the clinical activity score criteria(CAS) ,the patients were divided into active stage (CAS ≥ 4,35 patients) and inactive stage (CAS ＜4,51 patients).Eighty-six health adult persons were enrolled as the controls.The periphery blood of 3 ml was collected from each subject to detect the serum IGF-1 level by ELISA.Orbital adipose tissues were obtained during the surgery from 35 TAO patients and 35 patients with benign orbital tumor or orbital adipose prolapse from August 2009 to February 2014.The histopathological examination of orbital adipose tissue was carried out to evaluate the pathological characteristics, and the expression of IGF-1 in orbital adipose tissue was assessed by immunochemistry.This study protocol was approved by Ethic Committee of West China Hospital of Sichuan University, and informed consent was obtained from each subject before entering the cohort.Results The mean serum IGF-1 level was (0.862±0.026)ng/ml in the TAO patients,and that in the normal controls was (0.767 ± 0.480) ng/ml, without significant difference between them (P=0.281).The mean serum IGF-1 level was (0.877±0.355) ng/ml and (0.803±0.031) ng/ml in active stage and inactive stage of patients, respectively, and no significant difference was found between them (P =0.834).IGF-1 expression located in cellular membrane and cytoplasm.The expressing intensity of IGF-1 in orbital adipocytes was significantly enhanced in the TAO patients with the positive rate of 74.29% , and that in the controls was 45.46％ ,showing a statistical difference between the two groups (x2=5.289,P=0.021).Conclusions Serum IGF-1 level dose not rise in TAO patients, but the expression of IGF-1 in orbital adipocytes up-regulates, indicating that mature orbital adipocytes of TAO are regulated mainly by IGF-1.

Objective To understand the pathogenic bacteria distribution and drug resistance in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods The retrospective analysis was per-formed in the sputum culturs and drug resistance results of 740 patients with AECOPD. Results The positive rate of bacterial infection was 39. 1%. Among them, gram-negative bacteria were 196 strains (62. 4%), gram-positive bacteria 21 strains (6. 7%), and fungi 97 strains(30. 9%). The main kinds of gram-negative bacteria were Pseud-omonas aeruginasa, Acinetobacter baumannii,Klebsiella pneumoniae,Stenotrophomonas maltophilia and Escherichia-coli. Staphylococcus haemolyticus, Streptococcus pneumoniae and Staphylococcus aureus were the most frequent gram-positive bacteria. The major fungi was Candida albicans. Gram-negative bacteria showed high resistance to the third-generation cephalosporins,penicillins, moderate resistance to aminoglycosides,low resistance to imipenem. Gram-positive bacteria were resistant to many kinds of antibiotics, but they were responsive to linezolid and vancomycin. Fungi showed high sensitivity to antifungal agents. Conclusion The pathogens of AECOPD mainly are gram-nega-tive bacteria with a high drug resistance rate. To monitor pathogenic bacteria is conducive to master the pathogens distribution, drug resistance and provide the basis of rational use of antibiotics,which can slow down the emergence and spread of resistant bacteria.
