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 investigate the effect of patient-controlled epidural analgesia(PCEA) with opioids on serous myelin basic protein(MBP) and somatosensory evoked potential(SEP) of lower limbs in puerperants.MethodsA total of 120 puerperants,after receiving cesarean section,were divided into four groups by random number table method as group B,BR,MR and R randomly,and each group included 30 cases.After surgery,each case received PCEA:group B received 0.008％ butrophanol;group BR received 0.008％ butrophanol + 0.2％ ropivacaine;group MR received 0.004％ morphine +0.2％ ropivacaine and group R received 0.2％ ropivacaine only.VAS score,OAA/S score,adverse effect occurrence,concentration changes of serous MBP,SEP of both lower limbs and neurological function were observed at 2h(T1 ),4h(T2),8 h(T3),12h(T4),24 h(T5) and 48h (T6) after surgery.ResultsVASscoresofgroupBR(1.64±0.38,1.86±0.62,1.93±0.67) and MR( 1.74 ±0.39,1.91±0.58,1.98 ±0.63) at T3,T4,T5 were lower than those of group B(4.6 ±0.5,4.6 ±0.3,4.7 ±0.3)and R(2.64 ±0.41,2.83 ±0.91,3.37 ±0.87) (P＜0.05).There was no significance in four groups in OAA/S score at each point (P ＞ 0.05 ).Incidence of nausea ( 6 cases),vomiting ( 2 cases) and abdominal distention ( 5cases) of group M was higher than that of other three groups(P＜0.05).There was no significant difference in concentrations of serous MBP,SEP and neurological function in all four groups between preoperative time and 48h after operation(P＞0.05).ConclusionLower-dose and lower- concentration opioids used for PCEA have no influence on serum MBP and SEP.

OBJECTIVETo evaluate clinical outcomes of fixation for the treatment of radial head fracture with collapse of anterior articular surface.

METHODSFrom March 2006 to January 2013,17 patients with radial head fractures with collapse of anterior articular surface were analysed. According to the Mason classification, there were 12 cases with Mason type II fractures and 5 cases with Mason type III fractures. All the patients were treated with open reduction through posterolateral entrance of elbow joint and Herbert or titanium cannulated screw internal fixation.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months, with a mean of 11.3 months. According to the Broberg and Morrey score system, 2 patients got an excellent result, 12 good and 3 fair. There were no complications such as infection of elbow joint, nerve injury, non-union, traumatic osteoarthritis, heterotopic ossification and elbow instability. However, the postoperative activity range of elbow in the injuried side was less than that in the normal side.

CONCLUSIONRadial head fracture with collapse of anterior articular surface is easily misdiagnosed, and it can be treated with open reduction and internal fixation through posterolateral entrance.

OBJECTIVETo comparatively observe the curative effect, adverse reaction and compliance of Modified Xiaoyao Pill combining amitriptyline (MXP-At) in treating patients with depression.

METHODSSixty-four patients with diagnosis of depression matched to the Chinese Classification of Mental Disorders (CCMD-3) were randomly assigned to 2 groups, the treatment group treated with MXP-At and the control group with fluoxeline, 32 cases in each group. The curative effect was evaluated by Hamilton depression (HAMD) scale and the adverse reaction was recorded before treatment and at the 2nd, 4th and 12th week of the treatment. Patients were regularly followed up from the 12th week to the 24 th week. The curative effect and compliance in the two groups were compared.

RESULTSThe HAMD score dropped in both groups from the 2nd week of the treatment, and at that time, it was lower in the control group than that in the treatment group (P < 0.05); but at the 4th week, no significant difference was found in the therapeutic effect and the HAMD score between the two groups. However, 3 and 14 cases in the treatment and the control group were relapsed during the 12 weeks of follow-up respectively.

CONCLUSIONMXP-At shows a curative effect similar to fluoxetine on depression but with less adverse reaction, and is not expensive.
