Objective To evaluate the diagnosis, treatment and prognosis of occult breast cancer(OBC). Methods Clinical data of 12 OBC cases from June 1995 to June 2006 were retrospectively analyzed.Results There were 12 female; the mean age was 52.7 years(39～66). Tumor of all cases was in one of breasts, left(10 cases) or right(2 cases), 4 cases in pro- menostasis, 8 cases in post-menopause, and inci-dence of OBC in all kinds of breast cancer was 0.5% (12/2385). All cases were found because of lump in axillary fossa, the biopsy of 10 showed cases were lymph node adenocarcinoma metastatic, the fine needle aspiration of 2 cases were lymph node adenocarcinoma metastatic. Three cases were positive in the determi-nation of estrogen receptor of lymph node adenocareinoma metastatic. Two cases, suspecting breast cancer,could be found fine calcification in the examination of breast X-ray molybdenum target in 10 cases. Buhra-sound in 11 cases and near infrared ray scan in 10 cases did not detect cancer in breast; chest X-ray and Bultrasound in 10 cases and CT and all over the body bone scan in 5 cases did not found any cancer besides breast. Ten cases used modified radical mastectomy for breast cancer, one case radical mastectomy for breast cancer, one palliative operation. Pathological diagnosis of 9 cases after operation found breast primary le-sion, 6 cases were infiltrated duct cancer, 3 eases were intraductal cancer. All cases received radiotherapy and chemotherapy. Three cases which were positive in the determination of estrogen receptor of lymph node adenocarcinoma metastatic received TAM. Followed-up was made from 3 to 10 years, 11 cases were not found recurrence or metastses, and 5 cases had been living over 5 years. Conclusions OBC is one of rare special breast cancers. The powerful infiltrating capability leads to lump in axillary fessa in prophase and dis-rant metastses. The biopsy and fine needle aspiration would be used for diagnosis. Modified radical mastecto-my for breast cancer is the usual therapy method.

Objective To compare the results of three methods for measuring C reaction protein.Methods 100 patients were collected from our hospital,and three different methods for measuring C reaction protein were used to analyze the level of C reaction protein.Results Correlation analysis showed that the correlation between immunoturbidimetric assay and immunochromatography was higher.The differences of three methods assayed the C reaction protein were significant (P <0.05 )among normal people by the variance analysis,but had not statistical significance among abnormal people (P >0.05).The differences among all of test peo-ple were significant(P <0.05).Conclusion Detection of C reaction protein was important for diagnose inflammatory diseases.

Objective To analyze the influence factors of long-term efficacy of different fusion combined with pedicle fixation for lumbar spondylolysis.Methods The surgical and postoperative follow-up data of 196 cases with lumbar spondylolysis were analyzed retrospectively.Age,gender,body mass index ( BMI ),disease course,preoperative Japanese orthopaedic association (JOA) score,fusion segments,fusion method,immediate postoperative recovery rate and postoperative functional exercise,which might affectlong-term operation efficacy,were selected to undergo single-factor analysis and multivariate regression analysis.Results All the patients were followed up for 5-9 years and 5.4 years for average,163 cases got excellent or good curative effect,the rate of excellent and good effect was 83.2％( 163/196);33 cases got poor efficacy.There was no cerebrospinal membrane tear,cerebrospinal fluid leakage,infection,fracture fixation and other complications happened after operation.Single-factor analysis showed that disease course,BMI,preoperative JOA score and postoperative functional exercise had obvious relation with long-term efficacy (P ＜ 0.05 ) ;while age,fusion method,fusion segments,immediate postoperative recovery rate and gender had no significant relation with long-term efficacy (P ＞ 0.05).Multivariate regression analysis showed that disease course,preoperative JOA score,postoperative functional exercise were important factors influencing long-term efficacy (OR =1.423,2.089,1.320,P=0.023,0.012,0.034).Conclusions Disease course,preoperative JOA score,postoperative functional exercise are important factors influencing long-term efficacy of surgery for patients with lumbar spondylolysis.

Objective To evaluate the clinic efficacy of sufentanil and remifentanil by target- controlled infusion (TCI) combined with propofol in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).Methods Sixty patients,ASA Ⅰ ～ Ⅱ,undergoing elective EBUS-TBNA were randomly divided into group S ( sufentanil group),group R (remifentanil group) and group SR (sufentanil + remifentanil group),each group were twenty patients.The anesthesia of all groups is propofol intravenous anesthesia with 2％ lidocaine topical anesthesia,to controll BIS between 50 and 60 during surgery.Heart rate(HR),mean arterial pressure(MAP) pulse oxygen saturation( SpO2 ) and respiratory rate (RR) were recorded and compared 5mins after entering room(T0),30mins after the beginning of surgery(T1 ) and after surgery(T3).Arterial blood gas and the times of cough during surgery were also recorded and compared in all groups.The use of propofol and lidocaine,the wake-up time,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were also obtained.Results ( 1 ) RR decreased distinctly in group R and PaCO2 increased distinctly in group S and group R compared with that of group SR (P ＜0.05) during surgery.(2)The times of cough and the wake-up time lessened distinctly in group R and group SR compared with that of group S ( P ＜0.05 ).(3) The use of propofol and lidocaine,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were similar in all groups ( P ＞ 0.05 ).Conclusion Sufentanil compounded remifentanil by TCI combined with propofol is a safe and feasible anesthesia option for EBUS-TBNA,which provides better efficacy,high satisfaction and less side effects compared with using alone of sufentanil and remifentanil respectively.

Objective To investigate the methods and results of lengthened proximal femoral nail antirotation (PFNA) in the treatment of femoral shaft fractures combined with ipsilateral femoral neck fractures. Methods Of the 21 patients with femoral shaft combined with ipsilateral femoral neck fractures treated by lengthened PFNA from 2006 to 2009,16 patients with complete follow-up were retrospectively studied.There were 15 males and 1 female,at mean age of 35 years (range,21-51 years).Injury causes were all high-energy trauma including traffic injuries in 11 patients and fall injuries in five.According to Garden classification,there were seven patients with type Ⅰ femoral neck fractures,six with type Ⅱ and three with type Ⅲ.Femoral shift fractures contained six superior part fractures and nine medial part fractures and one inferior part fracture.According to Winquist classification,there were two patients with type Ⅰ femoral shaft fractures,four with type Ⅱ,six with type Ⅲ and four with type Ⅳ.Two patients had open fractures belonging to type Ⅰ Gustilo-Anderson.Harris hip score was used to evaluate functional outcomes at the last follow-up postoperatively. Result The mean follow-up time was 2.4years (range,1-4 years ).The mean period for healing of femoral neck and shaft fractures was 4.2months ( range,3-6 months) and 5.1 months ( range,3-8 months) respectively.Four patients showed delayed diagnoses of femoral neck fractures ; two patients had delayed union of femoral shaft fractures ; one suffered from avascular necrosis of the femoral head ; one patient presented 3 cm of extension of the affected limb and was accompanied by active pain of the knee joint for over four months.According to Harris score,function of hip joints was excellent in seven patients,good in six and fair in three,with excellence rate of 82％. Conclusions It is relatively few that the femoral shaft fracture is combined with ipsilateral femoral neck fracture.The rate of missed diagnosis of femoral neck fractures is high and the patients with high energy trauma hould be highly paid attention to.Lengthened PFNA conforms to characteristics of biomechanical fixation and presents short operation time and solid fixation. Lengthened PFNA achieves affirmatory effects for treatment of femoral shaft fractures combined with ipsilateral femoral neck fractures.
