Objective To describe the epidemiological characteristics and the control effect of hypertension in Liaoning area.Methods 8 452 Residents aged 15 and above 7 districts,Liaoning province,were selected with the multistage clustering sampling in 2002.Trained staff conducted the investigation on their economic status,gender,occupation,education,marriage,smoking,drinking,occupational physical activities and so on.Blood pressure,height,weight and waist circumstance were also measured.Results The blood pressure of all subjects was(126?22)/(79?12)mm Hg,with(127?11)/(80?11) mm Hg in urban residents and(125?21)/(78?12) mm Hg in rural residents,while(128?21)/(80?12)mm Hg in male and(125?23)/(78?11)mm Hg in female.The general prevalence of hypertension was 29.4%,and the general standardized rate of hypertension was 22.5%.The prevalent rate in city(32.3%) was higher than that in city(25.4%)(P

OBJECTIVE:
To explore the clinical efficacy of functional endoscopic sinus surgery (FESS) associated with radiofrequency ablation on chronic sinusitis.
METHOD:
Fifty-four patients with chronic sinusitis were divided randomly into two groups: the study group and the control group, The study group received FESS associated with inferior turbinate lateral fracture and radiofrequency ablation treatment, while the control group received FESS associated with inferior turbinate lateral fracture treatment.
RESULT:
The SNOT-20 score, Lund-Kennedy score, mucociliary clearance time and nasal airway resistance of the patients in the two groups after treatment were significantly improved than those before treatment (P < 0.05), and the sense of nasal congestion, headache and face pain, purulent rhinorrhea, postnasal drip, and other symptoms were also relieved. After treatment, the scores of SNOT-20 and the scores of Lund-Kennedy in the study group were significantly lower than those in the control group (P < 0.05), but no significant difference was found in mucociliary clearance time between the two groups after treatment.
CONCLUSION
FESS associated with radiofrequency ablation surgery is safe and effective for chronic sinusitis.

Objective To promote the cure rate of operation and to decrease the operative complications in patients with upper urinary tract stone Methods The data of 962 patients with upper urinary tract stone operatively treated in our department from 1975 to 2002 were reviewed and analyzed Results Residual stones were found in 109 out of 673 patients (11 3 %) Of the 109 cases, conservative treatment, nephrectomy and various methods of treatment were performed in 21, 12 and 76 cases, respectively Conclusion Strict control of operative complication, proper selection of the operation type and reasonable management of the complication are the important measures to improve the cure rate of upper urinary tract stone, to greatly decrease the occurrence of residual stones and to reduce the possibility of nephrectomy

?Objective: To study the effects of endogenous bone morphogenic protein 2(BMP 2) and 6(BMP 6) in rat facial nerve after injury. Methods: Facial nerve trunk was cut and then anastomosed in 30 adult male Sprague Dawley rats,another 6 rats without operation were used as the controls. Every 6 rats were killed 6 ,72 h,1, 2 and 4 weeks respectively after operation and nerve specimens were immunohistochemically examined for BMP 2 and BMP 6 expression. Result:In the control nerve the gray level of BMP 2 and BMP 6 were 210.89?8.21 and 232.03?9.25 respectively. 6, 72 h,1, 2 and 4 weeks after operation the gray level of BMP 2 were 242.83?11.01,240.67?7.91,234.46?5.28,232.12?7.27 and 220.71 ?10.19;that of BMP 6 210.75?5.19,204.08?10.85,198,91?8.58,186.37?4.11 and 184.62? 8.45 ,respectively. Conclusion: BMP 2 may play a role in the early irritable actions when facial nerve was injured. However, BMP 6 might have functions in the regeneration of facial nerve during later period after injury.
7.Relationship between muscarinic receptor subtypes and detrusor hyperreflexia in spinal cord transected rat
Chinese Journal of Urology 2001;0(08):-
Objective To investigate the relationship between muscarinic receptor subtypes and detrusor hyperreflexia. Methods Spinal cord was transected in male Wistar rats at L 1~2 level, changes of urodynamics were monitored 3 weeks later by cystometric studies.Spontaneous contraction frequency and strength of detrusor strip mustarded by carbachol (muscarinic receptor agonist), atropine (nonselective M antagonist), methoctramin (M 2 receptor selected antagonist) and 4 DAMP (M 3 receptor selected antagonist) were measured. Results Bladders after SCI showed littler capacity, lower compliance and hyperreflexia. Detrusor of all groups contracted at a definite tension. The contraction frequency in the hyperreflexia group (4.797?0.257 times/min) was higher than in the control's(3.227?0.173 times/min).There were no obvious changes while detrusor strips were mustarded by different muscarinic receptor antagonists.Carbachol could increase detrusor contraction frequency( 6.316 ?0.409 times/min) and the effect could be blocked by atropine(5.304?0.095 times/min) and 4 DAMP(5.046?0.089 times/min). Conclusions Detrusor is a rythmatic tissue at a difinite tension.Excitability rise of detrusor is the main cause of hyperrefexia. M 3 receptor can enhance the excitability of detrusor causing direct contraction.The function of M 2 receptor is still unclear.

Objective: To construct a high effective eukaryotic expre ss ing vector containing mcpr1 gene. Methods: mcpr1 gene w as amplified by PCR from the plasmid T-easy/ mcpr1, then PCR product was in serted into eukaryotic expressing vector pcDNA3.1/V5-His B. The positive recomb inant was identified by PCR analysis, HindIII and BamHI restriction analysis and Sequence analysis. Results: A 400 bp DNA fragment was amplified from the recombinant. Sequence analysis and restriction digest demonstrated tha t the mcpr1 gene was successfully inserted into pcDNA3.1/V5-His B plasmid. Conclusion: The eukaryotic expressed vector pcDNA3.1/V5-His B/ mcpr1 has been successfully reconstructed.
