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: This study aims to investigate the correlation between the expression of FoxP3, TGF-β1, and epitheli-al-mesenchymal transition (EMT) in breast cancer and to determine the clinical significance of FoxP3. Methods: The expression of FoxP3, TGF-β1, E-Cadherin, N-Cadherin, Vimentin, and Fibronectin protein were detected in the cancer cells of 74 cases with breast carcinoma via immunohistochemistry. The correlation of FoxP3 protein with clinico-pathologic features of breast carcinoma and the re-lationships among the expressions of FoxP3, TGF-β1, and epithelial-mesenchymal transition (EMT) were analyzed. Results:The ex-pression rates of FoxP3, TGF-β1, and EMT are 36.5%(27/74), 39.2%(29/74), and 40.5%(30/74), respectively. The FoxP3 protein ex-pression in breast cancer is correlated with lymph node metastasis (P<0.05) but not with other clinico-pathological features (P>0.05). The expression of FoxP3 is also correlated with the expression of TGF-β1. Furthermore, TGF-β1 can induce EMT (P<0.05). Conclu-sion:The expression of FoxP3 is correlated with lymph node metastasis and EMT in breast cancer. Therefore, FoxP3 may be a marker for predicting metastasis.

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.

AIM: To investigate the effect of l menthol on the absorption of ciprofloxacin (Cip) via the mucosa. METHODS: Mucosa absorption experiment and deposit effect were made on a two cells diffusion apparatus in vitro to calculate permeation coefficients. RESULTS: With increasing of the concentration of Cip, the permeation coefficient of mucosa absorption showed a increasing tendency, but deposit effect declined significantly. After using l menthol, the permeation coefficient of Cip showed a declining tendency. Especially at 0.2 percent concentration of l menthol, the decrease level was more obvious than other groups (P

Objective To study the changes of blood arginine vaso-pression(AVP)levels in patients with severe brain injury after treated with mild hypotherima.Methods Seventy-eight patients with severe brain injury were divided into mild hypothermia(33～35℃)group and normothermia group.The blood AVP levels and CSF AVP levels were determined at the third and the seventh day after brain injury.Results The AVP levels in blood and CSF of mild hypothermia group were lower than those of the normothermia group at the third and seventh day after brain injury(P＜0.05).According to GOS,prognosis of the mild hypothermia group was better than that of the nonnotbcrmia group(P＜0.05).Conclusion The mild hypothermia treatment may have inhibitive effects on the production of blood AVP,CSF AVP,and brain edema.Mild hypothermia is an effective method in the treatment of acute severe brain iniury in reducing the mortality and in increasing the survival rate.

Objective To improve clinicians'understanding of nephrotic syndrome and myasthenia gravis as adverse events of penicillamine(D-PA).Methods Two patients were reported to develope adverse reaction after taking D-PA.The related literature were reviewed.Result The first case was a systemic sclero- sis(SSc)patient treated with D-PA who developed nephrotic syndrome and blepharoptosis.The second case was a rheumatoid arthritis patient treated with D-PA who developed dysphagia and drinking bucking.The clinical symptoms were improved after disconting D-PA.Their conditions were stable up to now.Conclusion D-PA is used widely for various of autoimmune diseases.Clinicians should pay attention to these special and rare adverse effects.
