Objective To investigate the clinical efficacy of inserting a ureteral access sheath under direct view in flexible ureteroscopy with the help of rigid ureteroscope.Methods From March 2013 to July 2015,there were 68 patients accepted a ureteral access sheath in flexible ureteroscopy with the help of rigid ureteroscope for the treatment of kidney stones.There were 46 cases male,22 cases female,aged from 22 to 76 years old,average 43.9 years.There were 68 cases with backaches or hematuria.There were 48 cases with single stone,20 patients with multiple stones.There were 5 cases with stones on both sides.The stone diameter were from 1.2 to 2.5 cm,the average (1.83 ± 0.16) cm.There was no hydronephrosis in 18 cases,mild hydronephrosis 42 cases.The operations were carry out under general anesthesia.By using rigid ureteroscope placed zebra guidewire,then intercept F8 single lumen tip to 1.0 cm section on rigid ureteroscope,was placed into a modified 42 cm ureteral access sheath.Then the modified 42 cm ureteral access sheath was inserted under direct view with the help of rigid ureteroscope.Preoperative patient characteristics,radiographic stone size,operation time,success rate of lithotripsy,serious complications especially ureteral injury was recorded.4 weeks and 12 weeks after operation,ultrasound and/or CT were reexamined to assess the success rate of lithotripsy and the incidence ureteral stricture.Results All the procedures were successful.The operation time was (62.2 ± 6.5)min,the hospital stay was (3.1 ± 0.2) d.The success rate of ureteral access sheath completely placement was 97.1％,partially placement was 2.9％.Postoperative complications included Clavien classification grade Ⅰ 6 cases and grade II 2 cases.The postoperative follow-up averaged (12 ± 1.2) months for all case.The success rate of lithotripsy was 76.5％ in 4 weeks postoperative,and it was 95.6％ in 12 weeks.During the follow-up,compared with the preoperative cases,62 cases were not found to increase the degree of hydronephrosis.There were 58 cases (58/62) without hydronephrosis.4 cases were mild hydronephrosis (4/62).CT showed normal ureter 52 cases (52/52).Conclusions It was safe and reliable procedure with good results.It would be a safe procedure to inserting a ureteral access sheath under direct view in flexible ureteroscopy with the help of rigid ureteroscope.

Objective To analyze the clinical characteristics and risk factors for adult community-acquired pneumonia (CAP) caused by Gram-negative bacilli in Tangshan, and provide reference for the early identification of Gram-negative bac?teria CAP and the clinical use of antibiotics. Methods Data of retrospective general information, physical examination, aux?iliary examination and pathogen were collected in patients with CAP in respiratory department from 6 hospitals in Tangshan between October 2011 to September 2012. According to the above data, the prognosis of patients with the team score (PORT) was calculated. The sputum samples were isolated for pathogen identification. Univariate logistic regression analysis and multivariate logistic regression analysis were performed for risk factors of Gram-negative bacilli. Results A total of 195 strains were isolated from 172 (32.45%) patients in 530 patients with CAP. There were 154 strains of Gram-negative ba?cilli (78.97%) and 41 strains of Gram-positive bacteria (21.03%) in 195 bacterial strains. Univariate logistic regression anal?ysis showed the possible risk factors of Gram-negative bacilli in patients with CAP including age≥65 years old, using antibi?otics before hospitalization, basic diseases, cerebrovascular disease, malnutrion, white blood cell abnormal, neutrophil count<1 × 109/L, PORT classification≥Ⅲ, total bilirubin>17.1μmol/L and blood urea nitrogen>7.1 mmol/L. Multivariate logistic regression analysis showed the independent risk factors of Gram-negative bacilli in patients with CAP including us?ing antibiotics before hospitalization (OR=2.327, 95%CI 1.453-3.725), white blood cell abnormal (OR=2.904, 95%CI 1.879-4.490), PORT classification≥Ⅲ(OR=3.839, 95%CI 2.427-6.071), and blood urea nitrogen elevated (OR=4.133, 95%CI 2.585-6.606). Conclusion Clinical empirical anti-infection treatment should consider the risk factors including using antibiotics before hospitalization, white blood cell abnormal, PORT classification≥Ⅲ and blood urea nitrogen>7.1 mmol/L in patients with susceptible to Gram-negative bacteria infection.

OBJECTIVETo study the expression of livin at the invasive tumor front of oral squamous cell carcinoma.

METHODSForty-eight samples of oral squamous cell carcinoma were graded according to invasive front gading (IFG). The expression of livin was evaluated at the ITF and other parts of the same tumor using immunohistochemistry.

RESULTSSignificant difference in the pathological grades was found between the ITF and the other parts of oral squamous cell carcinoma (P<0.01). The expression of livin at the ITF was significantly stronger than that in the other regions (P<0.01). A significant positive correlation was noted between livin expression and the TFG score (P<0.05).

CONCLUSIONInhibition of cell apoptosis is more obvious at the ITF of oral squamous cell carcinoma than in the other regions. Livin overexpression at the ITF may indicate greater malignancy and higher likeliness of tumor recurrence and metastasis.

Objective To explore the expression of HR and Her?2 in breast cancer primary tumor and axillary lymph node metastasis. Methods Four hundred and twenty?eight female patients with unilateral breast cancer combined with axillary lymph node metastasis treated in the Affiliated Suqian Hospital of Xuzhou Medical University from January 2011 to January 2016 were selected in this study. Immunohistochemistry was used to detect the expression of ER,PR,Her?2 and Ki67 in primary tumor and axillary lymph node metastasis. Results The positive rates of ER expression were 75. 9% ( 325/428 ) and 70. 3% ( 301/428 ) respectively in primary tumor and axillary lymph node metastasis. The positive rates of PR expression were 61. 4% ( 263/428) and 56. 1% ( 240/428 ) respectively in primary tumor and axillary lymph node metastasis. The rates of Her?2 overexpression were 20. 1% ( 86/428) in primary tumor and the positive rate of Her?2 in axillary lymph node metastasis was 22. 7%( 97/428 ) . The positive rates of Ki67 expression were 45. 6%( 195/428 ) and 39. 7%(170/428) respectively in primary tumor and axillary lymph node metastasis. The expression of ER,PR,Her?2 and Ki67 in primary and axillary lymph node metastasis showed no statistical significance ( P>0. 05 ) . The molecular typing of primary tumor and axillary lymph node metastasis were not consistent in 31 patients ( 31/428,7. 24%) ,including 14 cases of primary tumor Luminal A,9 cases of Her?2 overexpression in axillary lymph node metastasis and 5 cases of triple negative breast cancer. Primary tumor Luminal B was detected in 10 cases, while 6 cases of Her?2 overexpression in axillary lymph node metastasis and 4 cases of triple negative breast cancer. Primary tumor Her?2 was overexpressed in 4 cases,while 1 case of Luminal A,3 cases of Luminal B in axillary lymph node metastasis. There were 3 cases of primary tumor triple negative breast cancer,while 2 cases of Luminal B in axillary lymph node metastasis and 1 case of Her?2 overexpression. Conclusion The expressions of ER, PR, Her?2 and Ki67 in primary tumor and axillary lymph node metastasis of some breast cancer were different. Immunohistochemistry for primary tumor and axillary lymph node metastasis of stage II?III breast cancer patients should be routinely carried out. Based on molecular typing of primary tumor and axillary lymph node metastasis,individualized treatment plan can be developed,so that patients will benefit from it.

In order to explore the treatment of Her-2 positive breast cancer patients who failed in multi-line treatments, we retrospectively analyzed the clinical data of a patient with refractory Her-2 positive breast cancer.The patient was initially diagnosed as Her-2 positive advanced breast cancer.After six line treatment in the outer hospital, the patient′s condition was basically in a progressive state.The breast tumor was broken and purulent, the lung metastasis increased, and the patient′s quality of life was poor.The patient was admitted to Department of Breast Surgery of Affiliated Suqian Hospital of Xuzhou Medical University, after MDT discussion, we gave pyrrolotinib combined with capecitabine treatment, the chest wound healed gradually, the lung metastasis gradually reduced, and the quality of life was better.A retrospective analysis of this case showed that pyrrolidine combined with capecitabine may bring hope to Her-2 positive breast cancer patients who failed to receive multi-line therapies, especially those who failed to target therapy.

The placement of the flexible ureteroscopic sheath during lithotripsy may injure the ureter. We have developed a double-tube flexible ureteral access sheath. Thirteen patients with renal calculi were treated with double-tube and flexible sheath in one stage. CT examination of 13 cases showed that the ureter was normal. The double-tube flexible ureteral access sheath makes the operation of sheathing easy, safe and effective.

Objective To explore the application of paclitaxel or docetaxel combined with cisplatin (TP) with cyclophosphamide,pirirubicin and fluorouracil (FAC) in the primary tumor molecular typing Luminal A,axillary lymph node metastasis three negative breast cancer. Methods From January 2012 to January 2014, the clinical data of forty-nine patients with were selected. All patients were divided into two groups by balance randomization method, TP group and FAC group. Twenty-five patients were treated with TP regimen and 24 patients were treated with FAC regimen. The clinical efficacy was evaluated after six cycles of chemotherapy. Chemotherapy effects,adverse reactions and survival rates of two groups were compared. Results All patients were given intravenous chemotherapy according to the plan and were evaluated for clinical efficacy. The response rate (RR) was 64. 0％ in TP group,including 4 cases of complete remission (CR),12 cases of partial remission (PR),7 cases of stable disease(SD) and 2 cases of progressive disease(PD). The adverse reactions were gastrointestinal reactions and granulocytopenia. The median progression-free survival ( PFS) and overall survival ( OS) were respectively 12. 4 months and 34. 1 months. In FAC group,the response rate ( RR) was 33. 3％,including 2 cases of CR,6 cases of PR,11 cases of SD and 5 cases of PD. The adverse reactions were gastrointestinal reactions,granulocytopenia and premature atrial contraction. The median PFS and OS were 7. 2 months and 20. 7 months respectively. The effective rate of TP group was higher than that of FAC group (χ2=4. 608,P=0. 032),and the progression-free survival time and total survival time were longer than those of FAC group (χ2 =8. 317, 8. 563, P=0. 004, 0. 003 ) . Conclusion Compared to FAC regimen, TP regimen could improve the survival rate of patients better with breast cancer of Primary tumor Luminal A and Axillary Lymph Node Metastasis Triple negative type, and adverse reactions were tolerated, it may be an optimized chemotherapy.
