Objective To analyze the clinical diagnosis and therapeutic effect of primary middle lobe lung cancer,in order to provide evidence for clinical diagnosis and treatment.Methods The clinical data of 45 cases of primary middle lobe lung cancer treated by surgery from January 2002 to January 2007 were ana- lyzed retrospectively.The operation style includes:simple middle lobectomy 12 cases(26.7 %),middle or up- per lobectomy 10 cases(22.2 %),right lung total resection 5 cases(11.1%).Chest exploration was done on 2 cases(4.44 %),palliative resection or vedged resection 2 cases(4.44 %).Results 1 case died from lung in- fection and respiratory failure(2.22 %).15 cases with arrhythmia (33.3 %), 1 case with chylothorax were cured after conservative treatment.The survival rate of 1,3,5 year were 82.1%,64.3 %,32.1% respectively. Conclusion The treatment of primary middle lobe lung cancer is dominated by regular lobectomy. It is difficult to perform middle lobectomy,so double or total lobectomy is done generally.Owing to the more postoperative complications, it should be cautious to perform sleeve resection.It should be avoided to do vedged resection for primary middle lobe lung cancer in order to lessen local recurrence.

Objective To investigate the feasibility and clinical effects of suture anchors technique for acute distal avulsion fracture of patella. Methods From January 2007 to July 2009, 33 patients(18males and 15 females, ranging from 28 to 72 years, with an average of 49.3 years) were treated with the suture anchors technique. The average time from injury to surgery was 3.5 days(2 to 7 d). Injury reason: traffic accident in 12 cases, injured in daily life in 11 cases, sports injury 9 cases, no clear trauma history in one case. The Bostman evaluation system, follow-up X-ray, and knee mobility were used to analyze the clinical effects of suture anchors technique. Results All patients obtained the follow-up and the average time was 16.5 months(12 to 23 months ). One patient suffered foreign body reaction, and his wound healing was good after operation. The remaining patient wound healing was good. No complications were found in all patients,such as popliteal fossa artery, tibial nerves or peroneal nerve complication. Bostman patella fracture functional score 27.3±2.3 points at the sixth months follow up, 28 cases were rated as excellent, 5 cases were good, and the excellent and good rate was 100%. Six months later, X-ray showed bone healing, knee activity recovered well. The Range of Motion was extension for -2.5°±2.1° and flexion for 122°±5.3°. Conclusion Suture anchors fixation in treatment of acute distal avulsion fracture of patella has a good efficacy, safety and reliability advantages, and without the second operation. This technique provides an alternative in lower pole patella fracture.

Objective To evaluation the comprehensive acquired immunodeficiency syndrome (AIDS) intervention program conducting in men who have sex with men (MSM) population living in Inner Mongolia Autonomous region. Methods A comprehensive intervention program was carried out among MSM groups in Hohhot and Baotou City. Seven hundred and six and 767 MSM were enrolled for investigation through the snowball method during May 2008 and May to June 2009, respectively.At the same time, 5 mL intravenous blood sample was collected from each subject for human immunodeficiency virus (HIV) detection and intervention effect evaluation. Data were analyzed by x2test. Results After intervention, the awareness rate of HIV/AIDS knowledge increased from 70.7%(499/706) to 81.7%(627/767) (x2 =25. 004, P＜0.01 ). The rate of consistent condom use in the last six months increased from 38.0%(254/668) to 45.3% (346/764) (x2=8. 269, P＜0. 05). The percentage of subjects who had more than 5 different male sexual partner during the last 6 months significantly decreased from 42.8% to 24.6% (x2 = 55. 348, P＜0.01). The median number of sexual partners in MSM decreased from 3 in 2008 to 2 in 2009. The HIV infection rate was 1.7 % in both 2008 and 2009. Conclusion The comprehensive intervention program among MSM population shows positive influence after one year implementation, which is helpful for increasing HIV/AIDS awareness and safe sex behavior in this population.

Objective To observe the effect of epidural injection with different dose of butorphanol on the rats' neurological function.Methods A PE-530 catheter was inserted into the epidural space of all the SpragueDawley rats (male, weighting 180 ～210 g) at L1-2 level.After three days, a total of 32 rats without any motor dysfunction were randomly divided into 4 groups as follows saline(NS) group (group C, n= 8 )and butorphanol injection (B) group( B1∶ n=8;B2∶ n=8;B3∶ n=8).Rats in group C were epidurally injected NS 30 μl each ,and rats in group B1, B2 and B3 were respectively epidurally injected Butorphanol 60 μg/30μl, 120 μg/30 μl,240 μg/30 μl (all diluted with NS) ,and 1 time per day for5 days.The neurological function of rats was recorded before injection (T0) and 6h after injection on day 1 ～4(T1 ～T 4) and 6h,24h and 72h after injection on day 5 (T5 ～T7) by BBB (BASSO,BEATTIE and BRESNAHAN ) Score and the inclined plane test .Results Compared with group C ,the BBB score and the inclined plane test of group B1 showed no significant difference throughout the experimental period(P＞ 0.05 ).There was also no significant difference at T0 ～ T3 of group B2 and group B3 compared with group C (P ＞ 0.05 ), while at T4, the BBB score ( ( 18.50 ± 2.00 ) points, ( 16.38 ± 2.33 ) points) and the inclined plane test( (58.75 ± 5.17 )°, (59.38 ± 3.20) ° ) of the two groups were both obviously decreased when compared with group C( (21.00 ±0.00) points, (65.00 ±3.78)°, P＜0.05) ,and the same significant differences appeared at T5,T6 and T7 (P ＜ 0.05 ).Conclusion Repeated epidural injection of butorphanol 60 μg have no effect on neurological function of rats,while repeated epidural injection of butorphanol 120 μg and 240 μg could impaire the neurological function.

OBJECTIVETo determine the exact location of the opening of the ejaculatory duct in men and provide some basic anatomical evidence for seminal vesiculoscopy and the treatment of ejaculatory duct obstruction.

METHODSWe performed ureterocystoscopy for 21 male patients aged 26 - 47 years with hematuria (n = 12), hematospermia (n = 2), glandular cystitis (n = 6), and anejaculation after radical resection of rectal carcinoma (n = 1), and meanwhile, with the consent of the patients, massaged the prostate and ejaculatory duct and observed the outlet of the expelled fluid. Under the microscope, we described the fluid samples with sperm as the expulsion from the ejaculatory duct.

RESULTSUreterocystoscopy showed that the exact anatomical sites of the expulsion of prostatic fluid and semen in the patients were the side and lower side of the prostatic utricle opening above the verumontanum and the ventral side of the verumontanum. Quantities of sperm were found in the expulsion fluid of 13 of the patients, and no expulsion, including semen, was seen from the prostatic utricle opening.

CONCLUSIONAnatomically, the ejaculatory duct openings of males are located at the two sides of the verumontanum adjacent to the opening of the prostatic utricle, rather than in the prostatic utricle above the verumontanum.
