Objective To summarize the clinical diagnosis and treatments of 55 reflux laryngitis (RL) pa-tients, and to study the relationship between gastroesophageal reflux disease (GERD) and RL. Methods The pa-tients went through the following diagnostic process consisting of the collection of medical history, laryngoscopy, gastroscope, X-ray barium meal examination, vocal evaluation, therapy of anti-acid and anti-reflux. Results The laryngeal manifestations of RL mainly consisted of laryngeal discomfort or foreign body sensation (89. 1%), chronic cough (36.4 % ), hoarseness (20 % ), laryngeal pain (18. 2 %), even severe aspiration or laryngismus (10.9%) and so on. With the laryngoscopy we could see congestion in arytenoids area (67.3%), swelling or pachynsis of a mucosal fold in interarytenoid area (43.6%), edema of true or false vocal cord(40%), a little dropsy staying in piriform sinus (32.70% ), contact ulcer or granuloma on posterior extremity of a vocal cord (20 % ), artificial sulcus under vocal cords (16.4 %). RL patients might have mild voice disorder, among whom 65.5 percent displayed ten-sion dysphonia. Fundamental frequency (F0), jitter, shimmer and normalized noise energy (NNE) of RL patients increased. Compared with the controls, there were significant differences (P<0. 05) except for the F0 of female pa-tients. The manifestation and physical symptoms were improved or disappeared after the treatment with proton pump inhibitor (PPI). Conclusion RL is one of the important manifestations of GERD out of digestive tract. Typi-cal RL manifestation is mainly a pathological process in the postero-glottis. Clinically, PPI can be used as not only a treatment but also a tentative diagnosis of RL.

Objective To study the activation effect of HBV RNase H protein on the transcription of cellular apoptosis susceptibility gene (CAS). Methods The promoter of DNA sequence of CAS gene was identified in GenBank by bioinformatics and amplified from HepG2 genome by PCR using sense (5′-GGTACCCGATTACATGTTGTACATGAAGG-3′) and antisence (5′-CTCGAGGCTGAGTTCCATTGCTATAG-3′) primers. As these primers contained Kpn I and Xho I recognition sites on their respective 5′-ends, the amplified DNA fragments were tested by sequencing and then subcloned into Kpn I/Xho I sites of pCAT3-Basic reporter vector by routine molecular biological methods. The reconstructed plasmid named pCAT3-CASp was identified by enzyme digestion of Kpn I/Xho I, in which the expression of chloramphenical acetyltransferase (CAT) was under the control of the promoter of CAS. The HepG2 cells were transfected by pCAT3-CASp, and then co-transfected by pCAT3-CASp and pcDNA3.1(-)-RH plasmids. At the same time, the empty pCAT3-basic and pCAT3-TXNRD1p were transfected (self-contructed by the authors) as controls. After 24h culturing, cells were collected and the expression of CAT activity was detected by ELISA according to the manufacturer′s protocol. Results The optical density of expression of CAT of pCAT3-CASp was 0.043 by ELISA, in contrast, the optical density of expression of pCAT3-Basic was 0.024. The expression of CAT in co-transfection of pCAT3-CASp and pcDNA3.1(-)-RH(0.065) was 1.5 times as higher as pCAT3-CASp plasmid (0.043), and 2.7 times as higher as pCAT3-Basic. Conclusions The CAS gene promoter identified in present study has transcription activity and HBV RNase H protein may activate the expression of CAS gene.

Objective To evaluate the safety and clinical effect of homemad Costant coronary stent implantation.Methods The immediate and two-year follow-up results of Costant coronary stent implantation in severe coronary heart disease(CHD)patients were retrospectively analyzedin the General Hospital of Shenyang Command of PLA and the Guanzhou People's Hospital from Mar.2001 to Aug.2003.Results Implantation of 86 homemad Costant coronary stents was successfully performed in 71 severe CHD patients although 3 main adverse cardiac events(MACE)occurred during hospitalization(2 patients died and 1 patient had sub-acute in-stent thrombosis).Follow-up was made in 63 patients for(21.5?4.4)months on an average and 4 patients died.Repeat coronary angiogram in 21 patients showed that in-stent restenosis for Costant stent existed in 4 patients and in-stent restenosis in other types of stent was found in 3 patients and in-stent restenosis in all stents was found in 1 patient who died of shock and neo-coronary lesions was found in 5 patients.Costant stent restenosis rate was 7.9%(5/63);MACE rate was only 12.7%(8/63)during follow-up.Conclusion Homemad Costant coronary stent can be safely implanted in severe CHD patients with ideal long-term outcomes.
