Objective To investigate the clinical value of uterine artery embolization on the treatment of cesarean scar pregnancy(CSP).Methods Clinical data of 112 cases of CSP patient underwent uterine artery embolization in Ningbo Women and Children's Hospital from January to December 2012 were enrolled for retrospectively analysis.Results All 112 patients underwent transvaginal ultrasound examination before admitted to hospital and among them 101 cases were diagnosed as CSP and 11 cases were suspected of CSP.Ninety-four cases were checked by magnetic resonance imaging (MRI) to measure the muscular thickness of uterine scar and the size of pregnant bursa.All patients received bilateral uterine artery embolization successfully,50-100 mg Methotrexat (MTX) were injected into uterine artery during this procedure.After uterine artery embolization,95 cases received curettage under ultrasound guidance,while 17 cases received curettage under hysteroscopy.All patients recovered as schedule.During the follow-up,no serious complication was found.Conclusion The use of uterine artery embolization in the treatment of CSP is safe and effective,and it can preserve patients' fertile ability.It is worthy recommended in the clinical application.

Objective To study the expression of insulin like growth factor binding proteins 3 (IGFBP-3) during inhi-bition of resveratrol (Res) on cell proliferation. Methods The inhibitory effect of Res on BGC-823 cells was determined by MTT method; Real-time qRT-PCR and western blot were applied to detect the expression of IGFBP-3 in Res-treated BGC-823 cells. In addition, cytometry was used to determine the proliferation and apoptosis of Res-treated BGC-823 after knockdown of IG-FBP-3 by siRNA. Results Upon Res (20,40, 80 and 160 μmol · L-1 ) treatment,the viability of BGC-823 cells was (82. 35±10. 65)% ,(74. 30±12. 36)% ,(62. 80±14. 66)% and (50. 75±11. 14)% , respectively. The mRNA and protein ex-pression of IGFBP-3 elevated as high as 2. 96-fold compared to the control group (P<0. 05). The cell viability of BGC-823 cells with IGFBP-3 knockdown was significantly higher than that of the wild type ( P < 0. 05 ) only at high Res concentration (160 μmol·L-1 ). Meanwhile,IGFBP-3 knockdown led to a significant decrease on cell apoptotic rate by Res (160 μmol·L-1 ) [(20. 13±9. 12)% vs (35. 48±11. 12)% ,P<0. 05)]. Conclusion Res can inhibit BGC-823 cell proliferation and promote cell apoptosis, the underlying mechanism of which may be related to the overexpression of IGFBP-3 in BGC-823 cells.

Objective The goal of this study is to compare the prognosis of recombinant tissue plasminogen activator (rt-PA) thrombolysis for middle cerebral artery (MCA) occlusion with patients with good and poor cerebral collateral circulation.Methods This retrospective study included 49 patients diagnosed with acute MCA occlusion and treated with rt-PA in the First Affiliated Hospital of Nanjing Medical University between October 1,2014 and February 1,2016.Patients were divided into good collaterals group (n =31) and poor collaterals group (n =18) according to their distribution of leptomeningeal arteries with CTA.Thirty day mortality rate,the incidence of symptomatic intracranial hemorrhage,24h and 30 day Stroke scores with National Institute of Health Stroke Scale (NIHSS) were compared between the two groups.Corrected chi-squared test,Fisher's exact test,or t test was used to statistical analysis as appropriate.Results The 30 day mortality rate of good collaterals group was significantly lower than that of poor collaterals group (0％ vs.16.7％,P ＜ 0.05).There were no significant differences in the incidence of symptomatic intracranial hemorrhage and 24h NIHSS score between the two groups (P ＞ 0.05),however,30 day NIHSS score of good collaterals group was significantly lower than that of poor collaterals group (7.2 ± 3.1 vs.9.6 ± 2.7,P ＜ O.05).Conclusion For patients with MCA occlusion and receiving intravenous thrombolysis,good cerebral collateral circulation may reduce their mortality and improve their clinical outcome after thrombolysis.However,good cerebral collateral circulation does not reduce the risk of symptomatic intracranial hemorrhage in those patients.

Objective To explore the effect of improved surgical method of intramedullary fibular allograft together with cannulated screw fixation combined with blood-activating and stasis-resolving Chinese medicine on the quality of life (QOL) of young and middle-aged fresh femoral neck fractures at intermediate stage. Methods A retrospective analysis was carried out in the articular orthopedics department of the First Affiliated Hospital of Guangzhou University of Chinese Medicine. The study involved 80 cases of young and middle-aged fresh femoral neck fractures receiving intramedullary fibular allograft together with cannulated screw fixation, and 50 qualified cases receiving cannulated screw fixation alone ( control group) . After the operation, all of the patients were given oral use of blood-activating and stasis-resolving Chinese medicine. After the last follow-up, Harris hip scoring, SF-36 scoring and radiographic evaluation were performed for the evaluation of clinical efficacy. Results The clinical application of intramedullary fibular allograft together with cannulated screw fixation combined with Chinese medicine was fulfilled in 80 hips of 80 cases. The follow-up period ranged from 48 to 84 months, averaging 62.68 ± 12.43 months. The improved surgical method group had an excellent and good rate of 93.75%, presented excellent-grade Harris scores and SF-36 scores, and had higher QOL scores than the control group (P<0.05) . After treatment, the two groups had statistically significant differences in the scores of SF-36 items of physical function ( PF) , bodily pain ( BP) , mental health ( MH) , vitality ( VT) , and general health ( GH) ( P<0.05 or P<0.01) , and also had significant differences in Harris scoring of pain, function and daily activities as well as the joint range-of-motion ( P<0.05 or P<0.01) . Conclusion The improved surgical method of intramedullary fibular allograft together with cannulated screw fixation combined with blood-activating and stasis-resolving Chinese medicine shows satisfactory therapeutic effect for young and middle-aged fresh femoral neck fractures at intermediate stages, which has the advantages of lower collapse rate after femoral head necrosis, less joint replacement, higher scores of the quality of life and Harris scoring, and better radiographic indicators than cannulated screw fixation alone.

BACKGROUND: Total hip arthroplasty is an effective measure to treat hip involvement in ankylosing spondylitis.Ankylosing spondylitis patients have different degrees of anemia after total hip arthroplasty. The hidden blood loss accounts for a large proportion of perioperative blood loss in total hip arthroplasty, and can affect the recovery of joint function.OBJECTIVE: To investigate risk factors of hidden blood loss after total hip arthroplasty in patients with hip involvement in ankylosing spondylitis.METHODS: We studied a consecutive series of 70 hips in 60 patients with ankylosing spondylitis hip involvement who were converted to cementless total hip arthroplasty. The average age of surgery was 35.12 years. The hidden blood loss was calculated according to Cross formula linear equation. The effects of operation time, erythrocyte sedimentation rate,C-reactive protein, body mass index, Bath ankylosing spondylitis radiology index, allogenic blood transfusion, and osteoporosis on hidden blood loss after total hip arthroplasty in patients with ankylosing spondylitis were analyzed. The patients were divided into the high blood loss group (≥ 480 mL) and the low blood loss group (< 480 mL) according to the high blood loss. Risk factors of high hidden blood loss after total hip arthroplasty in patients with ankylosing spondylitis were analyzed by single factor analysis and multivariate Logistic regression analysis (SPSS 17.0).RESULTS AND CONCLUSION: (1) The hidden blood loss after primary total hip arthroplasty in patients with ankylosing spondylitis was (737.76±419.18) mL, and the total blood loss was (1312.83±487.41) mL, and the percentage of hidden blood loss was 51.48%. The high blood loss group included 41 hips, and the low blood loss group included 29 hips; and the ratio was 41:29. (2) Single factor analysis showed that the operation time, Bath ankylosing spondylitis radiology index and osteoporosis, allogenic blood transfusion, decrease of hemoglobin were significantly associated with high hidden blood loss. (3) Multivariate Logistic regression analysis showed that Bath ankylosing spondylitis radiology index,allogeneic blood transfusion, and decrease of hemoglobin were significantly associated with high hidden blood loss. (4)Hidden blood loss is an important portion of total blood loss after primary total hip arthroplasty in patients with ankylosing spondylitis. Bath ankylosing spondylitis radiology index, allogeneic blood transfusion and decrease of hemoglobin are risk factors for high hidden blood loss.

Objective To analyze the pulse-field gel electrophoresis (PFGE) patterns and antibiotic resistance of Salmonella enteritidisstrains isolated in Longyan city in order to provide reference for effective control, clinical diagnosis and treatment of outbreaks of food-borne diseases.Methods Seventy-seven Salmonella enteritidis strains isolated from food poisoning cases, livestock and poultry meat samples collected for food safety risk monitoring and sporadic cases in 2014 and 2016 were analyzed by PFGE.Antibiotic susceptibility testing was carried out to determine the minimum inhibitory concentrations (MIC) of 16 common antibiotics to 57 strains.Results Seventeen PFGE types were identified among the 77 Salmonella strains including three predominant types (P4, P6 and P8) and were grouped into three major pulsotypes (Cluster1-3) at 90% similarity level.The predominant types causing outbreaks of Salmonella enteritidis infection were P8, P6, P4 and P14, which were responsible for five cases of food poisoning.These isolated strains were highly resistant to nalidixic acid (93%), followed by resistance towards ampicillin (74%) and streptomycin (54%).Forty-one strains were resistant to three or more antibiotics (71.93%).Conclusion The PFGE types of Salmonella enteritidis strains isolated in Longyan city exhibit polymorphism and are clustered into three major pulsotypes.PFGE molecular typing can provide early-warning of sporadic outbreaks and help to identify the sources of infections in Salmonella enteritidis-related food poisoning.Attentions should be paid to multidrug resistant Salmonella enteritidis.Surveillance for multidrug resistant strains and usage of antibiotics should be strengthened.
