Retrospective study of diagnosis and treatment of renal oncocytoma / 北京大学学报(医学版)

OBJECTIVE@#To summarize the experience of diagnosis and surgical treatment of renal oncocytoma, and to evaluate the surgical results based on follow-up results, in order to find the best strategy.@*METHODS@#In the study, 21 cases with renal oncocytoma from December 2003 to April 2016 in Peking University Third Hospital were retrospectively analyzed, including 4 males, and 17 females, with 10 cases on the right side and 11 cases on the left side. Their age was between 15 to 80 years (average: 58 years). Ultrasound or CT examination after admission was conducted. Ultrasound examination showed solid nodules. CT manifestations were solid masses with enhancement, and the tumor size was between 1.5 cm to 6.5 cm (average: 3.3 cm). Of the 21 cases, 9 were located in the middle of kidney, 7 were located in the upper pole, and 5 were located in the lower pole. After preoperative examination, according to the size and location of the tumor, laparoscopic partial nephrectomy or laparoscopic nephrectomy was performed, respectively.@*RESULTS@#All the operations were successful, in which 17 cases underwent laparoscopic partial nephrectomy (including 3 cases which were converted to open surgery), and 4 cases underwent laparoscopic radical nephrectomy. The operation time ranged from 75 to 274 min (mean: 144 min), and the blood loss ranged from 10 to 1 000 mL (mean: 115 mL). The postoperative hospital stay time ranged from 6 to 13 d (average: 8.2 d). The pathological results were all renal oncocytoma. In the study, 17 cases were followed up while 4 cases were lost to follow-up. The follow-up time ranged from 12 to 175 months (mean: 44 months). One case died in 20 months after operation with unknown reason, and there were no recurrence or metastasis in the other 16 cases.@*CONCLUSION@#Renal oncocytoma is a benign tumor with good prognosis. Enhanced CT is an effective diagnostic method in assistant examination, but it is difficult to differentiate clear cell carcinoma only from the naked eye. It is worthwhile to measure CT value at different stages of the tumor by picture archiving and communication systems (PACS), and to compare with CT value of adjacent kidney tissue may improve the diagnostic efficiency of CT. Laparoscopic surgery is an effective treatment for renal oncocytoma. We recommend laparoscopic partial nephrectomy for the patients with renal oncocytoma as the best choice if conditions permit.

Preliminary evaluation of acupuncture and continuous multi-point pulse stimulation for treatment of subjective tinnitus / 中国针灸

<p><b>OBJECTIVE</b>To put forward a method for assessing therapeutic effect on tinnitus and to observe the therapeutic effects of acupuncture and continuous multi-point pulse stimulation on subjective tinnitus.</p><p><b>METHODS</b>Continuous multi-point pulse stimulation was given at Ermen (TE 21)/ Tinggong (SI 19)/ Tinghui (GB 2), Yifeng (TE 17), Shenting (GV 24), Baihui (GV 20), Cong'er No 1-3, etc., once every other day, thrice each week. The therapeutic effects were evaluated with a selfstipulated "tinnitus questionaire".</p><p><b>RESULTS</b>Of the 98 cases, 11 cases were cured, 36 cases were markedly effective, 28 cases were effective and 23 cases were ineffective with a cured rate of 11.2% and a total effective rate of 76.5%.</p><p><b>CONCLUSION</b>Combined acupuncture and continuous multi-point pulse stimulation has a better therapeutic effect on subjective tinnitus.</p>

Randomized controlled trials of acupuncture at Tiaokou (ST 38) for treatment of periarthritis of shoulder / 中国针灸

<p><b>OBJECTIVE</b>To study the basic therapeutic function of Tiaokou (ST 38).</p><p><b>METHODS</b>According to clinically multi-central randomized controlled and single-blind test principle, 257 cases of periarthritis of shoulder were divided into two groups, a test group (n = 124) treated with oral anti-inflammatory analgesic medicine combined with acupuncture at Tiaokou (ST 38), and a control group (n = 133) treated with oral anti-inflammatory analgesic medicine. Their therapeutic effects were compared.</p><p><b>RESULTS</b>The total effective rate for stopping pain was 96.0% in the test group and 91.7% in the control group with a very significant difference between the two groups (P< 0.01). And the total effective rate for improvement of shoulder activity was 86.3% in the test group and 59.4% in the control group with a very significant difference between the two groups (P<0.01).</p><p><b>CONCLUSION</b>Oral anti-inflammatory analgesic medicine combined with acupuncture has obvious therapeutic effect on periarthritis of shoulder, which is better than that of simple oral anti-inflammatory analgesic medicine.</p>
