The incidence rate of young women with breast cancer is increasing.Because of distinct biological characteristics of breast cancer in young patients,it is reasonable to identify who is the best one for breast-conserving surgery.Patients with systemic chemotherapy should be fully considered about fertility requirements.In addition,endocrine therapy combined with ovarian function inhibition can improve the effect,meanwhile,there should increase the proportion of patients with targeted therapy.

BACKGROUND:Majority of patients appeared different degrees of hip joint bursitis and gradual y developed into femoral head necrosis in the early rehabilitation process of severe acute respiratory syndrome. OBJECTIVE:To analyze various causes of the severe acute respiratory syndrome sequela, and to review the treatment method of femoral head necrosis. METHODS:The PubMed database, China Journal Ful-text database (CNKI), VIP database and Wanfang database were retrieved by the first author with computer for the related articles from January 1997 to August 2012. The key words of“infectious atypical pneumonia, sequela, femoral head necrosis, bone ischemia, etiology, infectious atypical pneumonia virus, conservative treatment, operation treatment, total hip replacement”in English and Chinese were put in the title and abstract to search articles. A total of 872 articles were screened out after primary retrieval, and eventual y 56 articles were included for review. RESULTS AND CONCLUSION:Severe acute respiratory syndrome sequela, femoral head necrosis, was related with the dose and duration of hormone, patient’s sensitivity to hormone, using method, the secretion of leptin and bone calcitonin, and also infectious atypical pneumonia virus. The femoral head necrosis caused by the above factors can be treated with conservative treatment to slow down the process of femoral head necrosis and delay prosthesis replacement. Eventual y, most of the patients wil receive surgical method. For the treatment of advanced severe acute respiratory syndrome sequelae femoral head necrosis, prosthesis replacement can get the best effect.

Objective To investigate the protective effect of Ca 2+ channal blocker(Verapamil)on the testis following testicular torsion in rats.Methods Forty healthy male Sprague-Danley rats were randomly divided equally into five groups:group A(sham operation),group B1(the left testis underwent 720? positive torsion,2 h later detorsion was performed),group B2(the process as group B1 except at 30 min before detorsion,intraperitoneal injection of physiological saline was performed),group B3(the process as group B1 except at 30 min before detorsion,intraperitoneal injection of 2 mg/kg Verapami was performed),group B4(the left testis underwent 720? positive torsion,and 2 h later the left testis was excised).Five days after operation,the bilateral testes(the right testis in group B4)were extracted and nitric oxide(NO),nitric oxide synthase activity(NOS),total antioxygen capacity(T-AOC)were measured.Results After detorsion,NO and NOS activity increased greatly,T-AOC decreased significantly in bilateral testes,but more obvious in the torsive testis;Verapamil could inhibit the changes.Conclusion The excessive production of NO and the decreased T-AOC may be the main causes of the contralateral testicular injury after unilateral testicular torsion.Verapamil can reduce the testicular injury in bilateral testes after testicular torsion/detorsion in rats.The resection of the torsive testis has protective effect on the contralateral one.

Objective To explore clinical characteristics and treatment for unexpected gallbladder carcinoma during laparoscopic surgery . Methods A retrospective analysis was made on clinical data of 12 cases of unexpected gallbladder carcinoma out of 4620 cases of laparoscopic cholecystectomy (LC) in our hospital from September 1997 to September 2015.Intraoperative frozen pathological diagnosis showed gallbladder cancer Nevin stage Ⅲin 1 case, and a conversion to open surgery of gallbladder cancer was conducted .The remaining 11 cases of gallbladder carcinoma were diagnosed by pathology after surgery .One case of Nevin stage Ⅰand 1 case of stage Ⅱwere not surgically treated .Of the other 9 cases of Nevin stage Ⅲ, there were 5 patients who refused surgery and 4 patients received open radical resection of gallbladder cancer at 10-18 d (mean, 14 d) postoperatively. Results The 5 cases of Nevin stage Ⅲwho refused open radical surgery were lost to follow-up.Two cases of stage Ⅰand Ⅱwere followed up for 63 months and 6 months after LC without recurrence .Of the 5 cases of stageⅢundergoing open radical surgery , 2 cases dead at 8 and 10 months postoperatively because of abdominal extensive metastasis and cachexia , and 3 cases dead at 10, 28, and 32 months postoperatively because of gallbladder carcinoma liver transfer . Conclusions The occurrence of unexpected gallbladder cancer should be taken into consideration during laparoscopic cholecystectomy .Timely and appropriate complementary therapy should be given .

OBJECTIVETo observe the effect of postoperative analgesia with dexmedetomidine on the survival rate of amputated finger replantation.

METHODS91 cases, who was going to receive amputated finger replantation, were randomly divided into group A (n = 48) and B (n = 43). PCIA (patient-controlled intravenous analgesia) was set immediately after operation in group A (fentanyl 1.0 mg + tropisetron 4.0 mg + 10 mg + dexmedetomidine 200 microg + saline 100 ml) and group B (same as group A except dexmedetomidine). Background infusion is 2 ml/h with a bolous of 0.5 ml and lockout time is 15 min. postoperative VAS score, Ramsay score, condition of replanted fingers and other adverse events at the 0-6 h, 6-12 h, 12-24 h and 24-48 h were recorded and analyzed.

RESULTSThe age, sex, height, weight, amputated time (Ts), revascularized time (Tt) in the two groups were not statistically different (P > 0.05). Postoperative VAS score in the two groups was significantly different at the 0-6 h, 6-12 h, 12-24 h and 24-48 h (P < 0.05), but Ramsay score was not (P > 0.05). The highest and lowest postoperative VAS score and Ramsay score were markedly different between two groups (P < 0.05). 3 of the 60 fingers in group A experienced vascular crisis and 2 underwent vascular explore surgery. 13 of 56 fingers in group B occurred vascular crisis, and 10 underwent vascular explore surgery, showing significant difference between the two groups (P < 0.05). PCIA adverse reactions showed no difference between the two groups (P > 0.05). Bradycardia and hypotension didn't happen in any patients in the two groups. 4 weeks after surgery, the survival rate was 96.7% (58/60) in group A, and 83.9% (47/56) in group B (P < 0.05).

CONCLUSIONPostoperative analgesia with dexmedetomidine as an adjuvant can increase the survival rate of replantation fingers with high safety.

Objective To investigate the operative procedure and the clinical result of the modified rectangle cross-finger flap based on the dorsal branches in the middle phalange to repair degloved avulsion of fingertip.Methods From January 2006 to March 2010,26 patients with the avulsions of fingertip were treated by the modified rectangle cross-finger flap based on the dorsal branch in the middle phalange of adjacent finger.There were 21 men and 5 women,with an average age of 31.6 years(range,17-56 years).Fourteen cases were crushed by machine,8 cases were pressed and 4 cases were tied.There were 8 index fingers,9 long fingers,4 ring fingers and 5 little fingers.The length of the avulsion was 1.1-2.6 cm.The flap was harvested from the dorsal of contiguous digital of their middle and proximal segment.The both dorsal branches of the both proper palmar digital nerves were cut off and were anatomized with the nerve end of the injured digit.The area of flaps ranged from 3.6 cm×2.3 cm-6.5 cm×3.2 cm.The donors were closed by skin graft.Results The pedicels were cut when 13-23 d after operation.Twenty-five patients were followed up for 6-28 months(mean,16.3 months).All flaps survived with satisfactory appearance,sensation and function.All flaps and donors were primary healing.Two point discrimination was 6-9 mm with an average of 7.8 mm.The postoperative outcomes were evaluated by the total active movement.The results were excellent in 17fingers,good in 7,and fair in 1.The rate of excellent and good was 96%.Conclusion The treatment of degloved avulsion of fingertip with the modified rectangle cross-finger flap based on the dorsal branch in the middle phalange is recommendable.The operative procedure of harvesting the flap is simple.There is enough blood to supply the flap and the surviving rate is high.The postoperative function of the injured hand can be recovered satisfactorily.The figure of flap is well and the sense of flap is sensitive.The technique can be operated in the last 4 fingers without thumb.

In order to reduce the impact of various noise in pulse signal, the quality estimation and filtering algorithms based on cyclostationarity are proposed to reprocess pulse signal. First, A quality evaluation index of pulse signal which named quality factor is defined by cyclic spectrum to describe the quality variation of the pulse signal affected by noise; Second, a cyclic correlation matched filter (CCMF) is designed to remove noise. The simulation of pulse signal is produced by ourselves and noise signal is provided by MIT-BIH physiological database are used to test the function of proposed method, and then the method is applied to the actual pulse signal. The results show that the quality factor can accurately reflect the quality of the pulse signal and the CCMF can effectively remove noise from pulse signal.
