OBJECTIVETo search all studies that had been published in the world with regarding to the effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complications and comparative functional outcomes in patients with giant cell tumours (GCT) of the distal radius and analyze them which were in high quality by means of Meta analysis, in order to give some evidences for the choice of method dealing with giant cell tumors GCT in surgery.

METHODSCochrane central register of controlled trials(Issue 8 2014), PubMed(1970-01-01/2013-01-01), Ovid (1970-01-01/2013- 01-01), Elsevier (1970-01-01/2013-01-01), CNKI (1970-01-01/2013-01-01) were searched. Including intralesional curettage and wide excision were performed to treat giant cell tumors (GCTs) of the distal radius in the literatures, selecting on meet eligibility in the standard literatures underwent strict quality assessment. The Meta-analysis was performed with software RevMan5.0 from the Cochrane collaboration. Additionally, the analysis checked the heterogeneity of data. The effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complication in patients with giant cell tumours of the distal radius were evaluated and Odds Ratio was calculated.

RESULTSSeven relevant articles were identified involving total 163 cases. Among them, 92 cases were intralesional curettage (PMMA, n = 54; bone graft, n = 33; no PMMA or bone grafts, n = 5) and 71 cases were wide excision. The patients in the intralesional curettage group had a higher recurrence rate [OR = 3.87, 95% CI (1.42, 10.53)],especially for Campanacci grade 3 GCTs [OR = 10.12, 95% CI (1.57, 65.27)], yet fewer major complications [OR = 0.13, 95% CI (0.04, 0.40)] than the wide excision group. The use of PMMA versus bone graft did not affect the recur- rence rate [OR = 0.96, 95% CI (0.26, 3.56)]. By selecting the system evaluation of MSTS, the VAS and dynamometer, the result showed that the intralesional curettage group was equivalent or preferable to wide excision in terms of function rehabilitation.

CONCLUSIONBased on data obtained from the limited number of studies available, intralesional curettage appears to be moreappropriate for the treatment of local lesions (Grade 1 and 2) than Grade 3 GCTs of the distal radius. Moreover, PMMA was not additionally effective as an adjuvant, the intralesional curettage group was found to be equivalent or preferable to wide excision in terms of function rehabilitation.

OBJECTIVETo introduce a new technique for the treatment of helical keloid.

METHODSThe procedure consisted of two steps. In the first step, a kidney-shaped expander of 50 ml was placed subcutaneously in the retroauricular area. Routine inflation with normal saline followed. In the second step, about two months afterwards, the expander was taken out and the helical keloid was excised. The expanded flap was advanced to cover the wound.

RESULTSThe operation has been performed on 12 patients of 16 sites of helical keloid since 2000. Postoperative follow-up from 3 months to 2 years revealed satisfactory results. The reconstructed ear maintained a good contour.

CONCLUSIONThe technique creates a retroauricular flap rich in blood supply, which can be used to close the defect left by helical keloid excision. It provides a good treatment for the helical keloid replaced with normal skin from the mastoid region.

OBJECTIVETo evaluate the clinical therapeutic value of (188)Re-HEDP combined with pamidronate in breast cancer with bone metastasis.

METHODSForty-eight patients with breast cancer with multi-bone metastases were randomly divided into three groups:15 patients received (188)Re-HEDP (group A), 15 patients received pamidronate (group B) and 18 patients were treated by (188)Re-HEDP plus pamidronate (group C).

RESULTSThe overall pain relief rate was 73.3%, 80.0%, 100.0% in groups A, B and C. The response rate of bone metastasis was 40.0%, 33.3%, 66.7% in groups A, B and C respectively. The therapeutic effect of group C was better than those of groups A and B (P < 0.05), without any significance in the difference (P > 0.05).

CONCLUSIONThe therapeutic effect of (188)Re-HEDP combined with pamidronate for breast cancer with bone metastasis is remarkable in bone pain relief and bone metastasis control, which is better than either (188)Re-HEDP or pamidronate alone.

BACKGROUNDLiddle's syndrome is a rare autosomal-dominant monogenic form of salt-sensitive hypertension. This study aimed to screen the gene mutation in β and γ subunits of the epithelial sodium channel (ENaC) of a Chinese family with Liddle's syndrome, an autosomal dominant form of hypertension.

METHODSDNA samples from the proband with early-onset, treatment-resistant hypertension and suppressed plasma renin activity were initially screened for mutations in the C-terminal exons of the ENaC β or γ subunit genes, using amplification by polymerase chain reaction and direct DNA sequencing. We also screened the C-terminus of SCNN1B and SCNN1G in family members, and screened for the mutation in 150 controls.

RESULTSGenetic analysis of the β ENaC gene revealed a missense mutation of CCC to TCC at codon 616 in the proband, her mother and her grandmother. One hundred and fifty randomly selected controls had not the mutation, indicating that this is not a common genetic polymorphism. There was no mutation of the γ ENaC gene in any of the individuals examined.

CONCLUSIONSThrough direct DNA sequencing analysis, we established the diagnosis of Liddle's syndrome for the proband and her families, and provided tailored therapies to this abnormality. These results provide further evidence that Pro616Ser is a critical amino acid that has a key role in the inhibition of sodium channel activity.

OBJECTIVETo evaluate the efficacy and timing of re-transplantation for hepatic artery complications after orthotopic liver transplantation.

METHODSBetween December 2003 and December 2006, the clinical data of 13 patients diagnosed as hepatic artery complications after liver transplantation were retrospectively analyzed.

RESULTSThere were no significant difference in duration of operation and anhepatic phase between the initial transplantation and the second transplantation (P = 0.291, P = 0.312). However, intra-operative blood loss [(3.1 +/- 1.1) L vs. (1.5 +/- 0.9) L, P = 0.005] and intensive care unit stays [(4.3 +/- 1.8) d vs. (3.2 +/- 2.5) d, P = 0.015] were significantly increased in the re-transplant patients. No perioperative mortality occurred. The postoperative mortality of liver re-transplantation was 38.5% (5/13) including acute renal failure in two patients, severe infection in two and heart infarction in one. The other 8 patients were followed from 6 months to 51 months, with a median survival time of 22.5 months.

CONCLUSIONSLiver re-transplantation is the only viable option for patients with irreversible graft dysfunction secondary to hepatic artery complications after liver transplantation. Proper indication and optimum time of re-transplantation, reasonable individual immunosuppression regime and effective perioperative care program contribute to the increase of the survival rate of the patients performed liver re-transplantation.

OBJECTIVETo evaluate the short term clinical effects and surgery methods of the total hip arthroplasty (THA)for the treatment of Crowe type IV congenital dysplasia of hip (CDH) in adults.

METHODSFrom March 2013 to March 2015, 20 patients (20 hips) with Crowe type IV CDH in adults were underwent THA, including 4 males and 16 females, with an average age of 52 years old ranged from 32 to 68 years old. All the cementless acetabular cups were placed at the original anatomic location. S-ROM prosthesis was adopted together with subtrochanteric transverse osteotomy in femoral side. All the patients were evaluated by using the Modified Harris Hip Score. Radiographic evaluations were made preoperatively and during follow up.

RESULTSThe incisions were healed by first intention. There was no hip dislocation events and venous thrombosis occurred. All patients were followed up for 8 to 60 months with an average of 38.1 months. Postoperative X ray films showed all acetabular prosthesis were in true acetabulum. No nonunion and loosening were found in all patients. Harris score at final follow up improved from preoperative 50.90±9.35 to postoperative 90.25±3.16. The difference was statistically significant (<0.05). There were 1 patient with femoral split fracture, 1 patient with nerve injury, 1 patient with heterotopic ossification of Brooker I. The hip function of all patients was good, the pain was disappeared.

CONCLUSIONSTHA with S-ROM prosthesis and subtrochanteric osteotomy is an effective method for the treatment of Crowe type IV CDH in adults. The recent clinical curative effect is satisfied.

Objective:Our study was aimed to analyze the therapeutic effect of early sequential enteral nutrition on postoperative rehabilitation in patients with gastric cancer.Methods:Patients with gastric cancer receiving surgery at our hospital from 2016 to 2017 included and the clinical information was prospective collected and analyzed.Patients were randomly divided into two groups using random number table.Patients in group A were sequentially given amino acid type,short peptide type and then whole protein type,while those in group B received whole protein formulation only.The recovery of gastrointestinal function,postoperative systemic inflammatory response,six-minutes walking test,and enteral nutrition-related complications were compared between the two groups.Results:A total of 71 patients were included in this study (Group A 36 cases,Group B 35 cases).There was no significant difference in terms of the restart anal exhaust between the two groups (P ＞ 0.05).Patients in group A had a significantly shorter postoperative hospitalization (t =4.070;P ＜ 0.01) and the earlier restoration of oral intake than that of Group B (t =3.400;P =0.001).One week after surgery,the levels of CRP (t =2.547;P =0.013) and IL-6 (t =3.172;P =0.002) were significant lower in group A when compared with group B.In addition,patients in group A had a significant higher six minutes walk steps than those in Group B [(416.1 + 36.7) m vs (358.9 ± 32.7) m;t =6.927,P ＜ 0.01].However,no significant difference in enteral nutrition-related complications was found between the two groups (P ＞ 0.05).Conclusion:In patients with gastric cancer,early sequential enteral nutrition can effectively accelerate the postoperative rehabilitation.
