Background and Purpose:The recurrent rate of breast cancer after mastectomy was 5%~20%,high risk factors were included it could achieve 34%~40%,Chest wall recurrence was the most common.This paper explores the reason for chest wall recurrence of breast cancer after mastectomy,hoping to find an efficient way to prevent and reduce chest wall recurrence after mastectomy.Methods:For 39 patients with local recurrence on the chest wall after mastectomy clinical data was reviewed retrospectively.Results:This group of patients was 5.1% of all breast cancer patients in the same period.Most of recurrences(59.0%)occured within two years affer operation.The recurrent rate of T_1～T_4 was 1.6%、1.9%、9.7% and 37.2% respectively.Rate of chest wall recurrence in patients with negative axillary nodes and positive axillary nodes was 1.3%、7.6%,but if the amount of positive axillary nodes≥4,it was 13.4%.Conclusions:In the patients who had more positive axillary nodes,larger primary tumor and no proper adjuvant therapy,recurrence on the chest wall was seen more often.Adjuvant chemotherapy and postoperative radiotherapy are efficient ways to prevent recurrence on the chest wall.

Objective To investigate effect of sorafenib on serum hepatoma marker in patients with advanced hepatocellular carcinoma. Methods 101 patients with advanced hepatocellular carcinoma were selected, and divided into two groups.50 cases in control group were treated with routine clinical treatment, and 51 cases in experimental group were treated with sorafenib on the basis of control group.The survival time, adverse reactions, VEGF, CTGF, HIF-1 and OPN levels were compared after the treatment.Results The survival time of experimental group was higher than control group (P<0.05).Compared with control group, the serum levels of VEGF、CTGF,HIF-1, OPN,AFP, CEA, and CA199 in experiment group were lower (P<0.05,P <0.01).There were no significant differences of total adverse reactions between experimental group and control group. Conclusion Sorafenib can effectively prolong survival time of patients with advanced hepatocellular carcinoma, reduce serum VEGF, CTGF, HIF-1 alpha and OPN levels.

Objective To evaluate the clinical efficacy and safety of retroperitoneal laparoscopic pyelolithotomy in the treatment of intrarenal pelvic staghorn calculus or multiple renal calculi. Methods Fifteen patients(9 males and 6 females)with average age of 40 years old were treated. The diameters of the calculi were from 1.5 cm to 3.7 cm. Three trocars were used in this procedure as rou-tine. The renal sinus was exposed by separating the pelvis from outside to inside until reaching the in-fundibulum of the renal calyx. Then the renal calyx was cut open and the calculus was taken out. Double J stent was placed in the ureter and the incision of pelvis was closed by 3-0 absorbable suture. The drainage tube was pulled out 3-4 d post-operatively according to the drainage quantity. Double J stent was then pulled out 2 weeks after surgery. Results All the 15 procedures were successfully completed. The average operation time was 170 min and the average post-operative hospital stay was 7 d. During the 3-15 months' follow-up, 2 patients had calculus remnants with the size of 0. 2-0.5cm in diameter. Conclusions Retroperitoneal laparoscopic pyelolithotomy provides a minimally inva-sive treatment option in patients with intrarenal pelvic staghorn calculus or multiple renal calculi. It has the advantages of good exposure, little bleeding, small incision and fast recovery.

Objectives To explore the impact of Aβ oligomer(Aβo) and fibrillar Aβ( Aβf) on the ethology of model rat and to explore whether or not piper kadsura ohwi(PKO) can ameliorate the ethological changes.Methods AD animal model was made by continuous intracerebroventricular infusion of Aβ through mini-osmotic pump.After surgery,rats of Aβo + PKO group and Aβf + PKO group received intraperitoneal injection of 10％PKO everyday,rats from Aβo + DMSO group and Aβf + DMSO group received intraperitoneal injection of 2.5％ DMSO.The treatment lasted 5 weeks.Morris water maze experiment began on the 31st day after surgery.Results ( 1 ) Acquisition trials:the escape latency was longer in Aβo group ( ( 89.40 ± 7.20 ) s ) than that in Aβf group ( (65.00 ± 10.89 ) s ) ; escape latency was shorter in Aβf + PKO group ( ( 34.00 ± 11.26 ) s) than that in Aβf group and Aβf + DMSO group( (60.6 ± 6.95 ) s) ; escape latency was shorter in Aβ3o + PKO group ( ( 65.33 ±8.89) s) than that in Aβo group and Aβo + DMSO group ( ( 85.60 ± 6.02) s).( 2 ) Robe trial:the times ( 3.00 ±0.71 ) and the proportion of time (0.23 ± 0.02 ) and path(0.23 ± 0.04) spent in the target quadrant in Aβo group was less than that in Aβf group(6.00 ± 1.58,0.25 ± 0.01,0.26 ± 0.03 ) ; the three parameters in Aβf + PKOgroup were more than those in Aβ3f group and Aβf+ DMSO group; the three parameters in Aβo + PKO group were more than those in Aβo group and Aβo + DMSO group.Conclusions Aβ oligomer had a more severe impact on the ethology of AD model rats than fibrillar Aβ did; piper kadsura ohwi may ameliorate the ethological changes of AD model rats.

BACKGROUND:Flexible intramedulary nailing and external fixation for pediatric femoral shaft fractures are two common methods in the clinic. It remains controversial which fixation methods are better. OBJECTIVE:To systematicaly evaluate the therapeutic effects of flexible intramedulary nailing and external fixation for pediatric femoral shaft fractures. METHODS: A computer-based search was performed on PubMed, Embase, Medline, and Cochrane library for literatures on clinical controled trials of flexible intramedulary nailing and external fixation for pediatric femoral shaft fractures published before November 25, 2014. Literature language was not limited. The age of subjects was from 3 to 15 years. Modified Jadad was utilized to assess methodological quality of the included studies. Meta-analysis was carried out using Stata 12.0 software. RESULTS AND CONCLUSION:Six papers involving 237 patients were included. Meta-analysis results showed that compared with external fixation, a low incidence of overal complications [relative risk (RR)=0.30, 95% confidence interval (CI): 0.19-0.46;P < 0.001] and pin-hole infection (RR=0.286, 95%CI: 0.13-0.61;P= 0.001), but a high risk of needle tail irritation (RR=1.86, 95%CI: 1.35-2.56;P < 0.001) were found folowing flexible intramedulary nailing. No significant differences in other complications were found between the two groups. These results confirm that compared with external fixation, elastic intramedulary nail has fewer complications and faster fracture healing. Elastic intramedulary nail is recommended for single pediatric femoral shaft fractures. However, external fixation is a better option for high energy injury of lower limbs, multiple trauma or severely soft tissue injury.

Objective To establish a flow cytometric measurement of detecting minimal residual disease(MRD) according to the leukemia-associated immunophenotypes in children with acute lymphoblastic leukemia(ALL) and to explore the significance of MRD detection in ALL children for a individualized treatment. Methods A variety of four-color fluorescent antibody combinations were used to investigate the children's normal bone marrow. The normal bone marrow pattern at two-parameter plots was established to identify the residual tumor cells, seventy-five bone marrow samples from newly diagnosed ALL children were analyzed with four-color cytometry to determined the optimal combinations which can clearly distinguish the tumor cells from normal cells. The bone marrow samples were monitored with the combination panel in 60 patients at the end of induction therapy and follow-up treatment. Cytomorphology test, PCR amplification of 29 fusion genes as well as IgG and TCR gene rearrangements were performed simultaneously. Results Sixty-nine cases (92.0%) could be identified for effective antibody combinations to monitor MRD by four-color cytometry. Fusion genes or IgG and T cell receptor (TCR) gene rearrangements can be detected in 21 cases (28.0%) to monitor MRD by PCR. No MRD can be detected in 25 bone marrow samples at the end of induction therapy and follow-up treatment. Four-color cytometry could detect as low as 0.021%-4.130% residual leukemia cells. Conclusion MRD can be monitored by flow cytometry which is faster than PCR, and the sensitivity is superior to morphology method.

Objective To evaluate the efficacy and safety of modified transurethral plasmakinetic enucleation of prostate (M-TPEP) combined with cystolithectomy in elderly patients with high risk of large volume benign prostatic hyperplasia (BPH) complicated with large urinary bladder calculi. Methods Seventy-one patients with high risk of large volume BPH complicated with large urinary bladder calculi were selected, and the patients were treated with M-TPEP combined with cystolithectomy. The operation time, intraoperative blood loss, hospitalization time, complications, and the maximum urinary flow rate (Qmax), post-void residual volume (PVR), serum potassium, international prostate symptom score (IPSS), quality of life (QOL) score preoperative and postoperative 3 months were recorded. Results Seventy-one patients successfully completed the operation, and no death occurred. The operation time was (75.48 ± 6.51) min, intraoperative blood loss was (82.63 ± 10.08) ml, and postoperative hospitalization time was 5-7 d. Incidence of intraoperative capsule perforation was 2.82% (2/71), incidence of postoperative temporary urinary incontinence was 7.04% (5/71), incidence of urethral and bladder irritation after operation was 8.45% (6/71), and incidence of postoperative wound infection was 2.82% (2/71). The PVR, IPSS and QOL score 3 months after operation were significantly lower than those before operation: (6.89 ± 0.74) ml vs. (205.13 ± 40.08) ml, (2.71 ± 0.45) scores vs. (28.62 ± 3.57) scores and (1.36 ± 0.24) scores vs. (4.93 ± 0.38) scores, the Qmaxwas significantly higher than that before operation: (22.46 ± 2.97) ml/s vs. (5.24 ± 0.43) ml/s, and there were statistical differences (P＜0.01);there was no statistical difference in serum potassium between before operation and 3 months after operation (P＞0.05). Conclusions M-TPEP combined with cystolithectomy has short operation time, quick recovery after operation and low complication rate. It is a proper operative method for the elderly patients with high risk of large volume BPH and large urinary bladder calculi.

Objective:To evaluate the efficacy of different carotid artery revascularization strategy in sychronous carotid and coronary artery revascularization.Methods:The clinical data of 53 patients receiving simultaneous carotid and coronary artery revascularization in China-Japan Friendship Hospital from Jan 2014 to Dec 2019 was retrospectively analyzed. The clinical characteristics, imaging examination, treatment and prognosis were collected and reviewed. Patients were divided into CEA group (42 cases) and CAS group (11 cases) according to the carotid artery revascularization method.Results:The mean operative time and blood loss of CEA group were (288.81±43.28) min and (419.05±127.33) ml, respectively. The mean operative time and blood loss of CAS group were (251.82±23.16) min and (318.18±98.16) ml, respectively. The difference of operative time and blood loss between the 2 groups were not significant (all P>0.05). Four minor strokes, 4 transient ischemic attacks (TIA), 2 pulmonary infections and 4 recurrent laryngeal nerve injury were observed in CEA group. Two TIA and 1 re-thoracotomy for hemostasis occurred in CAS group. Conclusions:Both carotid endarterectomy and carotid stenting can achieve good clinical result in synchronous carotid and coronary artery revascularization procedure. The selection of proper carotid artery revascularization method should base on the lesion characteristic and surgeon's experience.

Objective:To investigate the effect of carotid endarterectomy(CEA) in the treatment of symptomatic carotid artery near-occlusion(CNO).Methods:Clinical symptoms, imaging examination, treatment and prognosis of 122 symptomatic CNO patients admitted to China-Japan Friendship Hospital from Jan 2014 to Jan 2020 undergoing CEA were retrospectively analyzed. Patients were divided into two groups based on the collapse condition,full collapse group(54 cases) and non-full collapse group(68 cases).Results:The difference was insignificant between the two groups at the 30-day and 12-month occurrence rate of primary endpoints(1.85% vs. 4.41%, P=0.629;7.41% vs. 4.41%, P=0.698).Postoperative re-stenosis occurred in one case in the non-full collapse group 8 months after CEA. Conclusions:CEA can achieve good curative effect for patients with CNO with recurrent symptoms, irrelevant to the existence of distal full collapse. The shunt can prevent intraoperative hypoperfusion and postoperative hyperperfusion.
