OBJECTIVE To investigate the expression profile of inflammation related genes in laryngeal squamous cell carcinoma by functional gene chip technique and to probe into the role of correlative genes in pathogenesis of the laryngeal squamous cell cancer and in tumor immunity. METHODS The total RNAs were respectively extracted from two pair samples of laryngeal tumor and the normal tissue around the tumor, and then were reversely transcribed to cDNAs, then synthesized to cRNAs. The cRNAs were labeled with the hybridization probes. The probes were then hybridized with four pieces of inflammation related genes chip. It was chemiluminescently detected and the acquired image was analyzed with special software. RESULTS Forty genes were differently expressed in inflammation related gene profile of laryngeal tumor, among which 22 genes were upregulated and 18 genes were down regulated. Thirteen genes were shown differential expression in both chips with 10 upregulated genes and 3 downregulated genes. CONCLUSION The differently expressed genes in inflammation related gene chips will provide clues and theoretical foundation for the investigation of the relationship between tumor and inflammation, and also the immune pathogenesis of laryngeal tumor. Furthermore CCL-7 may have an important role in the occurrence of laryngeal cancer, and the role of immunity of the pathogenesis of laryngeal tumor needs further studied.

Objective To investigate the distribution and drug resistance of Pseudomonas aeruginosa(PAE) in the hospital ,so as to provide the reference for the rational drug use and the infection control in clinical .Methods The infection distribution and drug resistance of 822 isolates of PAE were analyzed .The drug sensitivity test was proceeded by dilution method ,and the results were judged according to the relevant documents of the CLSI .The data was analyzed by WHONET 5 .6 software .Results 822 isolates of PAE were mainly distributed in intensive care unit ward ,general surgical department and respiration department .The sample was 82 .1% from sputum .The infection rate was the highest in autumn(30 .0% ) .The drug resistance rate of PAE to cefperazone/sul-bactam was the lowest(7 .6% ) ,and which to amikacin was 19 .1% .The resistance rates of PAE to other drugs were all higher than 20 .0% .Conclusion PAE is a common pathogen of respiratory tract infection ,which has a high resistance rate to the current clini-cal antibacterial agents ,and doctors should pay attention to the infection caused by PAE .

AIM: To study the protective effects of dexamethasone agains t ototoxicity of aminoglycoside antibiotics in guinea pigs. METHODS: Guinea pigs were divided into five groups. Group One: gentamycin, im; Group Two: amikacin, im; Group Three: gentamycin+ dexamethasone, im; Group Four: amika cin+ dexamethasone,im; Group Five: NS, im, all for two weeks. After three weeks, all animals were examined including tympanic mucous membrane reaction, nystagmu s depression rates and cochleae morphology. RESULTS: In Group Th ree and Four, the changes of morphology were slighter than those in Group One an d Two. CONCLUSION: Dexamethasone can weaken ototoxicity of amino glycoside antibiotics.

Objective To study the correlation between liver fibroindex and prognosis of hepatocellular carcinoma after hepatectomy.Methods The clinical data of 77 patients with hepatocellular carcinoma who underwent hepatectomy at the 5th Hospital Affiliated to Sun Yat-sen University from 2009 October to 2014 December were analyzed retrospectively.Using data from preoperative Fibroindex,these patients were divided into 2 groups,Group 1:Fibroindex ≤5.4,and Group 2:Fibroindex ＞5.4.The clinical pathological parameters and postoperative disease free survival rates in these groups were analyzed.The Cox ratio risk pattern analysis was used for factors correlating recurrence.Results The parameters in the 2 groups which included sex (35/0 vs 29/13),type of cirrhosis (23/12 vs 14/28),numbers of tumor (35/0 vs 26/16),maximal diameter of tumor (31/4 vs 23/19),vascular invasion status (32/3 vs 26/16),resection margin status (35/0 vs 36/6),hepatic vein/portal vein tumor thrombus status (35/0 vs 29/13),perioperative change of HBV DNA levels (23/12 vs 15/27)were correlated with postoperative recurrence,and they all showed significant differences (P ＜ 0.05).Disease free survival rate in Group 2 was lower than Group 1 (71.4％,33.7％,22.4％ vs 94.3％,46.2％,46.2％,P ＜ 0.05).The Cox regression analysis showed Fibroindex ＞ 5.4,AFP-L3％ ≥ 10％,and number of tumor ＞ 3 to be independent predictors of poor disease-free survival after hepatectomy for hepatocellular carcinoma (P ＜ 0.05).Conclusions Preoperative Fibroindex ＞ 5.4 was an independent adverse predictor of poor disease-free survival.It was valuable to predict postoperative recurrence in hepatocellular carcinoma patients.

OBJECTIVE: To investigate the preventive effect of Bushen Huoxue Recipe (BSHXR), a compound traditional Chinese herbal medicine, on autoimmune premature ovarian failure (POF) in mice. METHODS: Ovarian antigen was prepared with the ovarian tissue of female BALB/c mice. A mouse model of POF was established by immunization injection of the ovarian antigen of isotype female mice on multiple subcutaneous sites and two posterior soles. The POF mice were treated with BSHXR after the first and third immunization. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in peripheral blood were detected by enzyme linked immunosorbent assay. RESULTS: Lymphocyte infiltration was appeared in ovarian stroma of POF mice. The levels of FSH and LH were evaluated and the E(2) level was decreased significantly (P<0.05). BSHXR could reduce the increased levels of FSH and LH, increase the level of E(2) and the number of growing and mature follicles. The efficacy of early treatment was better than that of late treatment. CONCLUSION: BSHXR can recover ovarian function in POF mice mainly by regulating the indiscriminate hormone level, and BSHXR has preventive effect on autoimmune POF in mice.

Objective To investigate the risk factors for coronary artery lesions (CALs) in children with Kawasaki disease (KD) in Lanzhou. Methods One hundred and seventy-four children with diagnosed KD were divided into CAL group and non-CAL group based on the existence of concurrent CALs. The age, gender, fever duration, intravenous immunoglobulin (IVIG) start time, IVIG dose, C-reactive protein (CRP), serum albumin, erythrocyte sedimentation rate (ESR), platelet (PLT), red blood cell count (RBC), hemoglobin and so on were compared. Results Among the 174 children, 46 children (26.44%) were complicated by CALs and 128 children were not. The differences of average fever duration, IVIG starting time, IVIG dose, PLT, CRP, ESR and RBC were statistically signiifcant (P<0.05). Conclusions When KD children has the fever durations>10 d, start of IVIG af-ter 10 days of fever, increase of PLT, CRP and ESR and decrease of RBC, clinicians should be alert to the risk of concurrent CAL.

Objective To investigate the effect of ultrasound?guided transversus abdominis plane block after general anesthesia induction on cyclic stress and postoperative analgesia in patients treated with abdominal surgery. Methods Sixty patients scheduled for elective abdominal surgery were divided into 2 groups with 30 cases in each. All were treated with ultrasound?guided transversus abdominis plane block after general anesthesia induction, and 30 cases in observation group received ropivacaine ,while those in control group saline. Anesthesia maintained by propofol combined with remifentanil during surgery ,and postoperative analgesia by sufentanil. The effect of anesthesia and operation were compared. Results Compared with control group,observation group needed less time for analepsia (P < 0.05) ,and there were lower blood pressure and heart rate at 2 min after skin incision and immediately after surgery (P < 0.05). Less propofol and remifentanil were needed in surgery and less sufentanil after surgery in observation group (P < 0.05). The VAS pain score was lower 1 h,4 h,8 h and 12 h after surgery (P < 0.05) ,and there were less times for pressing analgesic pump (P < 0.05). Patients in observation group had higher comfort degree after surgery (P<0.05). Conclusion Ultrasound?guided transversus abdominis plane block after general anesthesia induction is helpful to reduce intraoperative anesthesia used for anesthesia maintenance , and can improve patients′comfort after surgery.
