Objective:To investigate the correlation between the secreted frizzled related protein 5 (SFRP5), 25-hydroxy vitamin D [25(OH)D], retinol binding protein 4 (RBP4) and the degree of illness in elderly patients with type 2 diabetes mellitus (T2DM) and the evaluation value of curative effect.Methods:One hundred and thirteen elderly patients with T2DM who treatment in Taihu Hospital of Wuxi City from January 2018 to October 2019 were selected as the study group, and 113 healthy patients during the same period were selected as the control group. The serum levels of RBP4, SFRP5, and 25(OH)D were compared between the two groups, patients with different disease levels, and patients with or without vascular complications. Spearman was used to analyze the correlation between each index and the degree of illness, and Pearson was used to analyze the correlation between each index and the insulin resistance index (HOMA-IR). The receiver operating characteristic (ROC) curve and area under ROC (AUC) were used to analyze the value of SFRP5, 25(OH)D, RBP4 and the combination of the three to predict vascular disease in T2DM patients.Results:The levels of RBP4 , HOMA-IR in study group were higher than those in control group: (22.96 ± 2.26) μg/L vs.(11.28 ± 1.69) μg/L, 3.83 ± 0.70 vs.1.65 ± 0.59, the levels of SFRP5, 25(OH)D in study group were lower than those in control group: (9.28 ± 3.14) μg/L vs. (14.65 ± 3.38) μg/L, (32.65 ± 5.12) nmol/L vs. (51.29 ± 6.33) nmol/L, and the differences were statistically significant ( P<0.05). The level of RBP4 in severe group was higher than that in mild group:(26.91 ± 2.51) μg/L vs. (19.35 ± 2.23) μg/L, the levels of SFRP5, 25(OH)D in severe group were lower than those in mild group: (7.13 ± 2.98) μg/L vs. (11.25 ± 3.30) μg/L, (27.97 ± 4.56) nmol/L vs. (36.93 ± 5.50) nmol/L, and the differences were statistically significant ( P<0.05). The levels of SFRP5, 25(OH)D in patients with macrovascular disease were the lowest, followed by those with microvascular and those without vascular disease; the level of RBP4 in patients with macrovascular disease was the lowest, followed by those with microvascular and those without vascular disease, and the differences were statistically significant ( P<0.05). There was a positive correlation between RBP4 and the degree of illness and HOMA-IR ( P<0.05), and there was a negative correlation between 25(OH)D and SFRP5 and the degree of illness and HOMA-IR ( P<0.05). The AUC of SFRP5 for predicting vascular disease was 0.721, and the cut-off value was ≤11.14 μg/L , with a sensitivity of 78.21%, and a specificity of 60.00%.The AUC of 25(OH)D for predicting vascular disease was 0.786, and the cut-off value was ≤ 36.56 nmol/L, with a sensitivity of 87.18%, and a specificity of 65.71%. The AUC of RBP4 for predicting vascular disease was 0.816, and the cut-off value was greater than 21.45 μg/L , with a sensitivity of 57.69% and a specificity of 94.29%. The AUC of SFRP5 + 25(OH)D + RBP4 for predicting vascular disease was 0.847, with a sensitivity of 70.51% and a specificity of 85.71% ( P<0.05). Conclusions:In severe T2DM elderly patients with vascular complications, the levels of blood SFRP5, 25(OH)D and RBP4 are increased and significantly related to the patient′s condition and insulin resistance, and they can predict the occurrence of vascular disease.

Objective Bortezomib plus dexamethasone (BD) and bortezomib,epirubicin plus dexamethasone (PAD) are both front-line regimens of multiple myeloma.This study aimed to assess the efficacy and safety of BD versus PAD regimens in multiple myeloma.Methods All 208 patients with newly diagnosed multiple myeloma using either BD or PAD front-line regimens were enrolled between November 2006 and July 2014.Front-line chemotherapy regimens were 2-7 cycles.Response rates,overall survival,progression-free survival,and adverse effects were retrospectively analyzed.Results (1) In PAD group,the overall response rate was 82.9％ [complete response(CR) 28.6％,very good partial response(VGPR) 12.9％],which was similar as that in BD group [70.3％ (CR 26.8％,VGPR 5.1％),P =0.049].The estimated median progression-free survival was 34.0 months in PAD group versus 25.0 months in BD group (P =0.010).(2) The triplet regimen has a higher accumulated response rate along with chemotherapy cycles,but it didn't show any difference with the doublet regimen.(3) In elderly patients (＞ 65 years old),the overall response rates in two groups had no significant difference (P =0.769),while in patients ≤65 years old,PAD regimen were more effective than BD regimen (P =0.037).(4) Grade 3 and 4 adverse events were recorded with a higher number of patients in the PAD group than those in the BD group.Conclusions Compared with BD regimen,PAD regimen improves the initial response rates,especially deep responses,as well as progression-free survival in patients with newly diagnosed multiple myeloma.However,more severe toxicities are accordingly higher.In elderly patients,overall response rate,estimated median progression-free survival,and median overall survival are all comparable in both regimens.

Objective To explore clinical classification and strategies for irreducible femur intertrochateric fractures.Methods A retrospective study was conducted of the 96 patients with irreducible intertrochanteric fracture who had been treated from January 2012 through December 2014 at our department.They were 47 men and 49 women,aged from 48 to 97 years (average,78.5 years).We classified the fractures according to location of fracture line and mechanism of fracture displacement into 5 types:13 cases of type Ⅰ (sagittal irreducible fracture),7 cases of type Ⅱ] (coronal irreducible fracture),72 cases of type Ⅲll (sagittal plus coronal irreducible fracture),zero of type Ⅳ (irreducible fracture involving the lesser trochanter),and 4 cases of type Ⅴ (irreducible fracture involving the greater trochanter).All the patients were managed using different techniques for closed reduction and fixation with proximal femoral nails antirotation Ⅱ.Results Of this series,limited open reduction was eventually conducted in 7.The operation time averaged 40 min;the amount of intraoperative blood loss averaged 200 mL.Fracture reduction was rated as grade Ⅰ in 78 cases and as grade Ⅱ in 18.The follow-up time averaged 16.6 months (from 12 to 24 months).All the fractures got united after an average of 5.8 months (from 3 to 9 months).The function of the affected hip was rated at the final follow-up using Harris scoring system as excellent in 79 cases and as good in 17,with an excellent to good rate of 100％.Refracture happened in one patient due to striking injury,urinary infection occurred in 2 patients and no wound infection was observed.Conclusion According to the classification and reduction strategy proposed by us,satisfactory reduction and fracture fixation can be achieved in management of irreducible intertrochanteric fractures.

Objective To investigate the efficacy of lateral decubitus intramedullary nailing for treatment of subtrochanteric fractures of the femur.Methods From January 2012 to December 2015,23 patients with simple femoral subtrochanteric fracture were treated at Department of Orthopedic Trauma,Changhai Hospital.They were 15 males and 8 females,aged from 19 to 77 years (average,48.3 years).According to the Seinsheimer classification,there were 6 cases of type ⅡB,8 cases of type ⅡC,6 cases of type Ⅲ A,and 3 cases of type ⅢB.Their injuries were caused by traffic accident in 10 cases,falling from a height in 5 cases,and sprain in 8 cases.All patients were treated by closed reduction and anterograde intrarnedullary nailing at lateral decubitus.Their operative time,bleeding volume,fluoroscopic frequency,fracture healing time,functional recovery and complications were recorded and analyzed.Results Their operative time ranged from 55 to 80 min,averaging 65.7 min;their bleeding volumes ranged from 240 to 420 mL,averaging 304.3 mL;their fluoroscopic frequency ranged from 30 to 60 times,averaging 42.7 times.This cohort was followed up for 12 to 28 months (average,17.9 months).Their fracture healing time ranged from 4 to 10 months,averaging 5.5 months.Nonunion occurred in one patient but was cured by secondary operation.The HSS evaluation at the final follow-ups showed 17 excellent cases and 6 good ones,yielding an excellent to good rate of 100％.All the wounds healed by the first intention.No infection,deep vein thrombosis or implant failure was observed.Conclusion As lateral decubitus intramedullary nailing can achieve satisfactory clinical efficacy for subtrochanteric fractures of the femur,the body position of lateral decubitus may be a good alternative.

AIMTo evaluate the fertilization competence of spermatozoa from ejaculates and testicle when the oocytes were matured in vitro following intracytoplasmic sperm injection (ICSI).

METHODSFifty-six completed cycles in 46 women with polycystic ovarian syndrome were grouped according to the semen parameters of their male partners. Group 1 was 47 cycles that presented motile and normal morphology spermatozoa in ejaculates and Group 2 was the other nine cycles where male partners were diagnosed as obstructive azoospermia and spermatozoa could only be found in testicular tissue fragment. All female patients received minimal stimulation with gonadotropin. Immature oocytes were matured in vitro and inseminated by ICSI. The spermatozoa from testes were retrieved by testicular fine needle aspiration.

RESULTSA total of 449 and 78 immature oocytes were collected and cultured for 48 hours, 75.5 % (339/449) and 84.6 % (66/78) oocytes were matured in Groups 1 and 2, respectively. The percentage of oocytes achieving normal fertilization was significantly higher in Group 1 than that in Group 2 (72.9 % vs. 54.5 %, P 0.05). There were no significant differences in the rates of oocytes cleavage and clinical pregnancies in these two groups [87.4 % (216/247) vs. 88.9 % (32/36); 21.3 % (10/47) vs. 44.4 % (4/9)]. A total of 15 babies in the two groups were healthy delivered at term.

CONCLUSIONIt appears that IVM combined with ICSI using testicular spermatozoa can produce healthy infants, while the normal fertilization rate of in vitro matured oocytes after ICSI using testicular spermatozoa was significantly lower than using the ejaculated spermatozoa.

【Objective】 To detect autoantibodies in Chinese systemic sclerosis (SSc) patients and analyze the relationship between clinical phenotype and autoantibodies in SSc. 【Methods】 We sequentially included 93 SSc patients. Their general information and clinical data were gathered. The differences in clinical characteristics among autoantibody negative and positive groups were analyzed statistically. 【Results】 Anti-nuclear antibodies were detected in 82 (88.2%) SSc patients. The positive rate of autoantibodies was detected in 26 cases (28.0%) of anti-Scl-70 antibody, 24 cases (25.8%) of anti-SSA/Ro-52 antibody, 19 cases (20.4%) of anti-U1-snRNP antibody, and 16 cases (17.2%) in anti-CENP-B antibody, respectively. The patients with positive anti-SSA/Ro-52 antibody had a significantly higher morbidity rate of pulmonary arterial hypertension (P=0.016). Patients with anti-Scl-70 antibody showed a higher incidence rate of digital tip ulcers or gangrene (P=0.004) and cardiac damage (P=0.014). The patients with anti-U1-snRNP antibody had a higher prevalence of pulmonary arterial hypertension (P=0.047) and Raynaud’s phenomenon (P=0.019), and showed an increased trend in the occurrence of interstitial lung disease (P=0.058). Those with anti-CENP-B antibody had a lower IgG level (P=0.049) and higher ALP (P=0.010) and γ-GT (P=0.003). The incidence of autoimmune liver disease was increased in anti-CENP-B positive patients (P=0.001). 【Conclusion】 Different autoantibodies in SSc are associated with clinical phenotype, and may contribute to the diagnosis, evaluation, and prognostic judgment of the disease.
