ObjectiveTo investigate the association of hypertensive target organ damage with abnormal ankle brachial index (ABI) in high-risk hypertensive patients.MethodsDuring December 2008 to May 2009,a cross-sectional study was conducted to investigated the prevalence of abnormal ABI (ABI < 0.90) in 2674 community-dwelling,hypertensive patients,who aged > 40 years,without coronary heart disease,stroke/transient ischemic attack or known arteriosclerosis,from 18 centers in China. Data were acquired through history,physical examination,laboratory and other diagnostic tests.ResultsThere were 2615 subjects eligible for the full analysis set. The high-risk hypertensive patients with arterial wall thickening,arterial wall thickening and slightly elevated serum creatinine had a higher prevalence of abnormal ABI than their counterparts respectively ( P < 0.05 ). Compared with the normal group,the abnormal ABI group had a higher serum creatinine level on average (P < 0.01 ).After adjustment for certain factors including investigation center,demographic factors,cardiovascular disease (CVD) risk and CVD risk factors using an unconditional logistic regression model,arterial wall thickening ( OR 2.416,95% CI 1.395-4.183,P =0.0016 ) and slightly elevated serum creatinine ( OR 3.377,95% CI 1.267-8.997,P =0.0149) were positively associated with abnormal ABI. However,arterial wall thickening (OR 0.988,95% CI 0.576-1.695,P=0.9664) and microalbuminuria (OR 1.389,95% CI0.685-2.817,P=0.3621)were irrelevant to abnormal ABI.Conclusions So far as a high-risk hypertensive patient is concerned,there are significant statistical correlations between arterial wall thickening and/or slightly elevated serum creatinine and an abnormal ABI,but no significant statistical correlations between arterial wall thickening or microalbuminuria and an abnormal ABI is observed.

OBJECTIVE:
To study the psychological aspects of tinnitus patients, to analyze the distribution of psychologic obstacle in tinnitus patients, and then to provide information for diagnosing and treating tinnitus clinically.
METHOD:
All patients were detected their frequency and loudness of tinnitus. Then they were evaluated by symptom checklist 90 (SCL-90), life satisfaction scale, Pittsburgh sleep quality index (PSQI) and tinnitus handicap inventory (THI). All data were analyzed with statistical software SPSS11.0.
RESULT:
(1)There was no straight line correlation between frequency, loudness of tinnitus and the patient's scores from SCL-90, life satisfaction rating scale (LSR), life satisfaction index A (LSIA), LSIB, PSQI, THI. (2) To 76 tinnitus patients, some factors of SCL-90 were higher than internal nom. Compared with internal nom, tinnitus patients' score of LSR, LSIA and LSIB were all lower than it. Many of tinnitus patients had sleep disorder, the ratio was higher than internal nom. (3) Grouping these patients, based on the score of THI. To THI four grade group and THI five grade group, their satisfaction of lives were lower, some factors of SCL-90 were higher than internal nom. To THI five grade group, the ratio about sleep disorder was higher than internal nom.
CONCLUSION
There is no straight line correlation between frequency, loudness of tinnitus and the patient's scores from SCL-90, LSR, LSIA, LSIB, PSQ1, THI. Grouping based on the score of THI, the groups of THI four grade and THI five grade are approved that they have psychologic obstacle obviously, they should be paid close attention.

Objective:
: To investigate the efficacy and safety of the posterior endoscopic cervical foraminotomy (PECF) using ultrasonic osteotome for the treatment of cervical osseous foraminal stenosis,focusing on introduction of the advantages of ultrasonic osteotome in partial pediculectomy and ventral osteophyte resection in PECF.
Methods:
: Nineteen patients with cervical osseous foraminal stenosis who underwent PECF using ultrasonic osteotome in our institution between April 2018 and April 2021 were enrolled in this study. All the patients were followed up more than 12 months. The patients’ medical data, as well as pre- and postoperative radiologic findings were thoroughly investigated. The visual analogue score (VAS), Japanese Orthopaedic Association (JOA) score, cervical dysfunction index (Neck disability index, NDI), and modified MacNab criteria were used to assess the surgical efficacy.
Results:
: All the patients were successfully treated with PECF using ultrasonic osteotome. The pre- and postoperative VAS, NDI, and JOA scores were significantly improved (p<0.05). According to the modified MacNab criteria, 17 patients were assessed as “excellent”, two patients were assessed as “good” at the last follow-up. There was no dura tear, nerve root damage, incision infection, neck deformity, or other complications.
Conclusion
: Adequate nerve root decompression can be accomplished successfully with the help of ultrasonic osteotome in PECF, which has the advantage of reducing the probability of damage to the nerve root and dura mater, in addition to the original merits of endoscopic surgery.

Objective To observe the therapeutic effect of DENG Tie-tao's Foot-bath Recipe (mainly composed of Radix Achyranthis Bidentatae,Rhizoma Chuanxiong,Spica Prunellae,Fructus Evodiae,Ramulus Uncariae Cum Uncis,etc.)for the treatment of essential hypertension with hyperactivity of liver Yang syndrome. Methods Eighty essential hypertension patients with hyperactivity of liver Yang syndrome were randomly divided into treatment group and control group,40 cases in each group. Both groups were given basic antihypertensive western medicine treatment, and additionally the treatment group was given external application of DENG Tie-Tao's Foot-bath Recipe and the control group was given foot-bath with warm water. Seven days constituted one treatment course. Before and after treatment , the scores of traditional Chinese medicine(TCM)symptoms and Athens Insomnia Scale were observed , blood pressure variability (BPV)was detected with ambulatory blood pressure monitoring instrument , and plasma norepinephrine(NE) and epinephrine(E) levels were examined by enzyme-linked immunosorbent assay (ELISA). Results (1)The total effective rate for improving TCM symptom scores of the treatment group was 87.5%, and that of the control group was 75.0% , the difference being significant (P < 0.05). (2)The total effective rate for lowering blood pressure of the treatment group was 85.0%, and that of the control group was 72.5% , the difference being significant (P < 0.05). (3)After treatment,scores of Athens Insomnia Scale in the two groups were obviously decreased(P<0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P <0.01). (4)After treatment,24h BPV,daytime BPV and night BPV in the two groups were decreased to certain degrees (P < 0.05 compared with those before treatment),and the decrease of 24h BPV and night BPV in the treatment group was superior to that in the control group(P<0.05).(5)After treatment,plasma NE and E levels in the two groups were decreased to certain degree (P < 0 . 05 compared with those before treatment), and the decrease in the treatment group was superior to that in the control group (P < 0.05). Conclusion DENG Tie-Tao's Foot-bath Recipe exerts synergistic action on lowering blood pressure steadily by relieving TCM symptoms, improving the quality of sleep, decreasing 24hBPV of essential hypertension with hyperactivity of liver yang syndrome. And the regulation of plasma NE and E levels may be one of its therapeutic mechanisms.

Objective To study the application of pediculated skin flaps in the treatment of com-plicated long urethratresia. Methods From March 1999 to May 2006, a total of 18 male patients with complicated long urethratresia were treated by using the pediculated skin flaps. The causes of urethratresia were 7 cases of postoperative pelvic fractures with posterior urethral stricture, 4 cases of transurethral intravesical chemotherapy, 3 cases of postoperative bulbar urethral stricture, 2 cases of gonorrhea, and 2 cases of long-time urethral catheter placement. Four cases were urethratresia nf cor-pus penis, 7 cases were anterior urethral obliteration, 7 cases were posterior urethral and anterior ure-thral obliteration. Urethro-perineal fistulas were found in 8 cases, posterior urethrorectal fistulas in 7 cases, false passage formations in 8 cases. The average length of urethratresia was 15.1 cm (range 8. 7 to 23. 0 cm). The urethral scar was rasected, the posterior urethrorectal fistula was repaired, and different kinds of pediculated skin flaps depending on the length of urethratreaia was used. Results All the patients were followed up for 12 to 18 months (mean 14 months). Fifteen patients voided well 3 months postoperatively, none of the urography showed stricture. The mean peak urinary flow rate was 16. 9 ml/s (range from 16. 5 to 21.7 ml/s). Of the other 3 cases, 1 case experienced difficult voi-ding due to the long and circuitous tabularized skin flap but recovered after proper shortening;1 case had restenosis for the infection of anastomosis but voided well after excision and reanastomnsis;1 casehad a urinary fistula resulting from hematoma and infection, but was successfully treated by the neo-plasty of the urinary fistula. The mean peak urinary flow rate was 17.0 ml/s (range 15.0 to 22.0 ml/s) for 17 patients 6 months postoperatively, except for one who experienced genuine urinary incon-tinence. At 9-18 months after operations, the mean peak urinary flow rate was 17.5 ml/s (range 15.8 to 22.5 ml/s) for 17 patients. Conclusion The single-stage urethroplasty based on pediculated skin flaps is a reliable and durable method for complicated long urethratresia.
