Factors affecting the outcome of surgical treatment for intertrochanteric fractures / 中华创伤杂志

Objective:To investigate the factors affecting the outcome of surgical treatment for femoral intertrochanteric fractures.Methods:A retrospective case series study was conducted for 424 patients with intertrochanteric fractures admitted to four hospitals in Shanghai from January 2014 to December 2016. There were 200 males and 224 females, aged 45-98 years [(77.8±10.5)years]. Normal union was observed in 326 patients (normal union group), and abnormal union was founded in 98 patients including nonunion in 2 patients (abnormal union group). Data were recorded including the age, gender, injury side, AO classification, Evans-Jesen classification, thickness of femoral lateral wall, medial support, tip-apex distance, and screw position within the femoral head. Fracture healing was assessed. Univariate analysis was conducted to examine differences of the above factors between two groups, and Logistic regression was used to screen the main factors affecting fracture union. At the latest follow-up, the hip joint function was estimated according to the Oxford score system.Results:All patients were followed up for 1-3 years [(2.2±0.3)years]. Univariate analysis showed significant differences between two groups regarding the AO classification, Evans-Jesen classification, medial support, tip-apex distance, and screw position within the femoral head ( P<0.05). Multivariate regression analysis revealed that the simple fracture ( OR=1.030), medial support ( OR=0.395), tip-apex distance ≤25 mm ( OR=0.266) and inferior screw position ( OR=0.986) were significantly related to fracture union. The hip function in normal union group was (42.6±4.5)points, better than (35.4±3.2)points in abnormal union group ( P<0.05). Conclusion:The stability of intertrochanteric fracture is the most important factor for fracture union. The medial support, tip-apex distance ≤25 mm and inferior screw position are helpful to promote fracture healing and recovery of hip joint function.

Mechanism of lncRNA-PLUTO on promoting insulin biosynthesis and secretion / 中国药科大学学报

@#The aim of this study is to investigate the effect of long non-coding RNA PLUTO on β cell function and its underlying mechanism. Islet cells of db/db, ob/ob and HFD mice were isolated and extracted by enzymatic method to detect the expression of PLUTO in islet cells of different obesity model mice. Glucolipid toxicity was used to stimulate islet primary cells and Min6 cells, and the expression of PLUTO was detected to elucidate the reasons of PLUTO down-regulation induced by obesity factors. RT-qPCR and ELISA were performed to analyze the function of PLUTO on β cells; Western blot and rescue experiments were carried out to elucidate the regulatory mechanism of β cells by PLUTO. The results showed that the expression levels of PLUTO were significantly decreased in obesity model mice compared with control mice; over-expression PLUTO in primary islets and Min6 cells could improve insulin biosynthesis and secretion; Western blot analysis showed that PLUTO promoted insulin secretion and synthesis by up-regulating the transcription and translation of Pdx1, which is the adjacent gene of PLUTO.

Effect of transnasal transsphenoidal surgery on acromegaly caused by pituitary adenoma and its early biochemical index remission factors / 中华神经医学杂志

Objective To study the clinical efficacy of transnasal transsphenoidal surgery in acromegaly caused by pituitary adenoma and the clinical characteristics of patients achieved early biochemical remission after surgery. Methods Thirty-three patients with acromegaly caused by pituitary adenoma, admitted to and underwent transnasal transsphenoidal surgery in our hospital from September 2014 to June 2017, were chosen in our study. Clinical data and treatment efficacy of these patients were analyzed retrospectively. The patients were divided into biochemical remission group and non-biochemical remission group according to serum growth hormone (GH) trough value and insulin-like growth factor-1 (IGF-1) levels after oral glucose tolerance test (OGTT) 3 months after surgery, and endocrinology test results of the two groups were compared. Results Thirty-three acromegaly patients underwent microscopic transnasal pituitary surgery. For these patients, 24 achieved total resection, two achieved subtotal resection, 5 achieved massive resection, and two achieved partial resection. Patients were followed up for an average of 13.2 (3-36) months. At 3 months after surgery, blood sugar of two patients with diabetes were restored to normal level; reduction or restoration of hypertension was observed in most patients with preoperative hypertension (81.8％ , 9/11); improvement of cardiac hypertrophy or cardiac enlargement was observed in about 1/3 patients with preoperative cardiac organic changes; heart enlargement was improved in 4 patients; one patient had normal sinus arrhythmia. The average interventricular septum thickness of the patients after surgery was significantly reduced as compared with that before surgery ([8.36±1.56] mm vs. [9.22±1.24] mm, P<0.05). The early biochemical remission was achieved in 19 patients (57.6％); as compared with the 14 patients failed to achieve early biochemical remission, those patients achieved early biochemical remission had significantly smaller adenoma diameters and volumes, lower percentages of patients with degrees of adenoma packaging internal carotid artery<135° and Knosp grading 0-2, and higher extent of surgical resection, lower IGF-1 level at one week and three months after surgery, lower GH level one, two and three d, one week and three months after surgery, and lower GH trough value after OGTT before surgery, one week and 3 months after surgery, with significant differences (P<0.05). Conclusions Transsphenoidal surgery is effective treatment for acromegaly caused by pituitary adenoma. Most patients could achieve biochemical remission three months after surgery. And the surgery could help in improving the cardiovascular complications of patients. The patients who are able to achieve early biochemical remission may have the features of smaller adenoma, lower GH trough value after OGTT before and one week after surgery, and lower GH and IGF-1 levels after surgery.

Objecive To investigate the prevalence of NDM-type carbapenemases in the carbapenem-resistant Escherichia coli strains collected from Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The epidemiological characteristics of NDM-type carbapenemase-producing isolates were analyzed.Methods Eighteen strains were collected from November 2013 to January 2015 in the clinical microbiology laboratory of Ruijin Hospital. All of them were resistant to imipenem or meropenem (inhibition zone diameter≤19 mm). The blaNDM gene was detected by PCR. The amplified products were subjected to sequencing analysis. Conjugation experiment was carried out to verify the transferability of plasmids. Multilocus sequence typing (MLST) and pulsed field gel electrophoresis (PFGE) were performed to analyze the molecular epidemiology.Results The blaNDM gene was identified in 6 strains, 4 of which had blaNDM-1-type and 2 had blaNDM-5-type carbapenemase gene. Three strains were positive in the conjugation experiment. MLST analysis showed that 6 NDM carbapenemase-producing isolates belonged to ifve sequence types, corresponding to five PFGE-DNA patterns (A-E). Two of these isolates shared the identical sequence type (ST5018) and nearly the same PFGE-DNA patterns (A1, A2).Conclusions NDM-type carbapenemase-producing E. coli is identified in this study. Most blaNDM-positive cases were sporadic. Plasmid might play an important role in the spread of blaNDM inE. coli. The blaNDM-5 type carbapenemase gene was first identified in Shanghai, to which more attention should be paid.
