BACKGROUND:The number of elderly patients with hip fracture is huge, and this population mainly combines with a variety of internal diseases. The general condition was bad. Compared to total hip arthroplasty, bipolar hemiarthroplasty can shorten operation time, reduce the time of anesthesia and improve surgical safety, but the operation using which fixation mode is always controversial.
OBJECTIVE:To compare the safety and curative effects of bipolar hemiarthroplasty with cementless or cement femoral stem prosthesis in elderly patients with osteoporotic complex hip fracture.
METHODS:From June 2007 to June 2010, 198 elderly patients with osteoporotic hip fracture aged more than 75 years old, who were treated with bipolar hemiarthroplasty in the People’s Hospital of Xinjiang Uygur Autonomous Region, China, were enroled in this study. Al patients were divided into cementless group (n=69) and cement group (n=129) according to the type of prognosis. Osteoporosis was treated conventionaly in both groups after replacement. Operation time, intraoperative blood loss, incidence of postoperative hip pain, out of bed activity time post surgery, Harris scores of last folow-up and loosening rate of the prognosis were compared between the two groups.
RESULTS AND CONCLUSION:176 of above 198 cases were folowed up for 48 to 84 months, including 122 in the cement group and 54 in the cementless group. Operation time was longer in the cement group than in the cementless group, but out of bed time was earlier in the cement group than in the cementless group post surgery, and there were significant differences (P < 0.05). The incidences of loosening and hip pain were more in the cement group than in the cementless group post surgery (P < 0.05). No significant difference in intraoperative blood loss and Harris scores of last folow-up was detected between the two groups (P > 0.05). The incidences of loosening rate were 5% and 4% in the cement and cementless groups, respectively, which showed significant differences (P< 0.05). These results indicate that bipolar hemiarthroplasty with or without cement for osteoporotic hip fracture in the elderly can obtain good middle- and long-term effects. Bipolar hemiarthroplasty with cement can reduce the out of bed time, but operation time was longer, and incidences of hip pain and loosening were higher in cement prosthesis than in cementless prosthesis.

Objective To investigate the long-term efficacy of nonmyeloablative autologous peripheral blood stem cell transplantation(NAST) to cure refractory autoimmune disease(AD).MethodLong-term follow up of four cases of AD patients with NAST were summarized.The pretreatment regimen was intravenous injection of cytarabin (200 mg· kg-1· d-1 ) and cyclophosphamide (40 mg· kg-1· d-1).The therapeutic effect was evaluated by the change of symptoms and signs and long term complications.Changes of immune function were detected by flow-cytometry.ResultsFive cases of patients had been successfully engrafted.The average time for peripheral leucocytes count to reach 4.0×109/L was 12 days.It needed 10 days for platelets to return to 100×109/L and 22 days for hemoglobin to 120 g/L.Apparent remission of symptoms and signs was observed after transplantation.Lymphocyte subtypes analysis pre- and post- NAST showed that count of CD4+ and the ratio of CD4 +/CD8 + was returned to normal.One patient gave birth to a healthy baby four years after transplantation.Three female patients returned tonormal life. Conclusions Compared with classical myeloablative stem cell transplantation,NAST has a rapid hematopoietic recovery and good long-term therapeutic effect in AD.The quality of life in AD patients treated with NAST is higher than those treated with myeloablative hematopoietic stem cell transplantation.

ObjectiveTo evaluate the clinical efficacy and safety of nylon ligation combined with endoscopic high-frequency electric snare for the treatment of colorectal polyps.MethodsThe clinical data of 345 patients with colorectal polyps who received the treatment of nylon ligation combined with endoscopic high-frequency electric snare at the Zhongshan Hospital of Fudan University from January 2006 to January 2011 were retrospectively analyzed.Complications including bleeding and perforation were observed.Postoperative wound healing and local residual recurrence were assessed during follow-up.ResultsA total of 362 colorectal polyps were successfully removed.The mean diameter of the colorectal polyps was 2.7 cm (range,1.5-4.0 cm). Operative bleeding occurred in 1 patient,and perforation in 1 patient.The results of histological examination showed that 93.6％(339/362) colorectal polyps were adenoma,17 were hyperplastic polyps,5 were inflammatory polyps,and caneeration of colorectal polyps in 1 patient was detected.Endoscopic follow-up was completed in 334 patients at the first month after operation,and 9 patients with residual benign colorectal polyps received endoscopic resection.No residue or recurrence was found in the other patients.Endoscopic follow-up was completed in 308 patients at the second months after operation,and no residue or recurrence was found.The overall effective rate was 97.1％ (299/308).ConclusionEndoscopic nylon ligation combined with endoscopic high-frequency electric snare is effective and safe for the treatment of colorectal polyps.

Objective To compare the clinical efficacy and safety of two different conditioning regimens in nonmyeloablative autologous peripheral blood stem cell transplantation (NAST) for the treatment of systemic lupus erythematosus (SLE).Methods Different conditioning regimens were used in two groups:cytarabin combined cyclophosphamide in group 1 and ATG combined cyclophosphamide in group 2.Different recovery time of leucocytes,neutrophils and platelets in the two groups were compared.Statistical analysis were carried out by paired t-test.Results The mean time for peripheral leucocytes reaching 1.0×109/L,neutrophils getting up to 0.5×109/L,platelet raising to 100×l09/L and hemoglobin rising to 120 g/L in group 1 were [(7.2±1.3),(8.0±1.5),(10.5±1.4),(22.1±2.3)days] and [(10.4±2.1),(12.0±1.9),(19.3±2.1),(28.1± 2.4)] days in group 2.The difference was statistically significant (P＜0.01).CD4+ cell count and the ratio of CD4+/CD8+ of pre- and pro-NAST was changed.No significant differences were observed in the two groups.Conclusion For the sake of safety and hematopoietic reconstitution,we recommend cytarabin combined cyclophosphamide as the preferred conditioning regimen.

Objective To evaluate the clinical efficacy and safety of metallic hemoclips in the treatment of gastric defects during endoscopic full-thickness resection. Methods Patients with submucosal tumors derived from the muscularis propria and adhesion of the gastric serosa diagnosed by EUS and CT were enrolled in the study.A total of 62 patients,22 males and 40 females,mean age 58.5 years,were recruited into the present study from June 2009 to December 2010,in which 37 patients were with tumors in gastric fundus,20 in gastric body and 5 in antrum.All patients were treated with endoscopic full-thickness resection.After the operation,metallic hemoclips were used to close the defects through endoscopic biopsy channel.The closure success rate with metallic hemoclips were assessed.The patients were followed up endoscopically for evaluation of efficacy and safety of the procedures.Results All patients underwent endoscopic full-thickness resection.Uncontrollable bleeding occurred in 1 patient,who subsequently underwent emergent laparoscopic surgery and was excluded from the study.Metallic hemoclips were applied to close defects in 57 patients,and metallic hemoclips combined with omentum obstruction in 4 patients.The overall success rate was 100％ in 61 patients.Endoscopic follow-up was completed in all patients in average of 4.4 months.The clinical wound healing rate was 100％.No complications such as fever,abdominal pain were found in 2months after the procedures.Conclusion Application of metallic hemoclips during endoscopic full-thickness resection for gastric defects is a safe and effective technique.

Objective To evaluate the potential relationship between isoforms of BRCA1 associated RING domain 1 ( BARD1 ) and the pathophysiologic markers of sporadic breast carcinoma of female Han ethnic group. Methods The expression of BARD1 isoforms in 39 breast carcinomatous tissue, 12paracancerous-normal breast tissue and 7 controlled normal breast tissue was detected by reverse transcription polymerase chain reaction (RT-PCR) and then cloned and sequenced.The difference of isoforms expression and their clinical significance were analyzed. Results There were four transcriptive products of BARD1 found in all these candidates,named full lenth,isoform γ,isoform δ and isoform e.The positive rate of isoform γ and δ was higher in carcinomatous tissues than in paracancerous-normal tissues and normal breast tissue in healthy women ( P ＜ 0.05 ). Carcinomatous tissue expressed more kinds of isoforms.There was significant difference between carcinomatous tissue and paranormal/nomal tissue ( P =0.0075 ).There was significant correlation between isoform ε positive and poor prognosis factors such as poorly differentiation,HER2 positive,poor pathologic type and larger breast cancer lumps(P ＜ 0.05 ). Conclusions There are significant differences in the expression of BARD1 isoforms among different kinds breast tissues in the female Han ethnic group.Positive isoform ε may predict poor prognosis of breast carcinoma in the female Han ethnic group.

BACKGROUND:It is important to establish an ideal mouse model of severe aplastic anemia for investigating the mechanism and finding new therapies for aplastic anemia. OBJECTIVE:To establish a severe aplastic anemia mouse model by using recombinant human interferon-γand busulfan. METHODS:Sixty healthy Kunming female mice were randomly divided into two groups:model group (n=50) and control group (n=10). The model group was given recombinant human interferon-γat a dose of 1×104 U/d by intraperitoneal injection and busulfan at a dose of 18 mg/(kg·d) through stomach feeding for 7 days. The same volume of physiological saline was given to control group. Multi-parameters, including general condition, body weight, blood cellcount, morphology and biopsy of bone marrow were analyzed in two groups. RESULTS AND CONCLUSION:At day 7 after treatment, the weight, white blood cellcount, hemoglobin, blood platelet, reticulocyte count in model group were significantly lower than control group (P<0.05). Bone marrow smears and biopsy of model group showed marked reduction of bone marrow proliferation and increases of percentages of non-hematopoietic cellclusters and adipose tissue. The oil drop and fat vacuole were apparently seen in the model group. Severe aplastic anemia mouse model can be established by using recombinant human interferon-γand busulfan successful y, which is economic, stable and easy to operate.
