ABSTRACT
According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.
ABSTRACT
Objective:To explore the effect of small dose of low molecular weight heparin on the prognosis of elderly patients with severe pneumonia using systematic evaluation method.Methods:Databases including Wanfang data, VIP, CNKI, SinoMed, PubMed, Embase and Cochrane Library were searched for randomized controlled trial (RCT) studies about the comparison of conventional therapy and low molecular weight heparin on prognosis of elderly patients with severe pneumonia from the time of database establishment to August 2019. The patients in conventional treatment group were treated by improving ventilation, anti-infection, eliminating phlegm, relieving asthma and maintaining homeostasis while those in low molecular weight heparin group were subcutaneously injected with low molecular weight heparin of 4 000 U, once a day for 7 days. The patients' main outcomes included the oxygenation index (PaO 2/FiO 2) after 7 days of treatment, duration of mechanical ventilation, mortality in hospital, and secondary outcomes included acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and coagulation function after 7 days of treatment, the length of intensive care unit (ICU) stay, and incidence of bleeding. Data extraction and quality evaluation were conducted. The Meta-analysis of included studies that met the quality standards was performed using RevMan 5.3 software. Funnel diagram analysis was used to analyze the parameters with no less than 10 studies enrolled. Results:A total of 14 RCT studies were enrolled involving 1 173 elderly patients with severe pneumonia, among whom 590 received low molecular weight heparin while the other 583 received conventional therapy. All the included studies were well designed and of high quality. The results of Meta-analysis showed that compared with conventional therapy, small dose of low molecular weight heparin significantly elevated PaO 2/FiO 2 after 7 days of treatment [mean difference ( MD) = 19.25, 95% confidence interval (95% CI) was 16.88 to 21.61, P < 0.000 01], shortened the duration of mechanical ventilation ( MD = -48.88, 95% CI was -67.42 to -30.33, P < 0.000 01), and decreased mortality in hospital [odds ratio ( OR) = 0.40, 95% CI was 0.22 to 0.73, P = 0.003] and APACHEⅡ score after 7 days of treatment ( MD = -3.38, 95% CI was -3.94 to -2.83, P < 0.000 01), and shortened the length of ICU stay ( MD = -4.51, 95% CI was -5.75 to -3.27, P < 0.000 01). There was no significant difference in the changes of coagulation parameters after 7 days of treatment or the incidence of bleeding between low molecular weight heparin group and conventional therapy group [7-day thrombin time (TT): MD = 0.57, 95% CI was -0.15 to 1.28, P = 0.12; 7-day prothrombin time (PT): MD = 0.32, 95% CI was -0.35 to 0.98, P = 0.35; 7-day fibrinogen (FIB): MD = -0.17, 95% CI was -0.45 to 0.10, P = 0.22; incidence of bleeding: OR = 0.86, 95% CI was 0.36 to 2.07, P = 0.74]. The funnel diagram showed that there was publication bias of included 10 studies about APACHEⅡ score after 7 days of treatment. Conclusion:Small dose of low molecular weight heparin can improve the prognosis of elderly patients with severe pneumonia and it has no obvious side-effect on coagulation function.
ABSTRACT
Coronavirus disease 2019 (COVID-19) outbreak started in December 2019 that caused difficulties for clinical work. Practical work experience in our spinal outpatient and emergency department during the COVID-19 pandemic is summarized in this article, with combined evidence-based medical evidence to explore a standardized process of diagnosis and treatment for spinal diseases. Outpatient reservation, continuous screening, triage, and isolation, first consultation accountability system, pandemic reporting system, and online revisit were strictly followed. We hope that our experience in prevention and control of COVID-19 can help spine surgeons globally in stopping the spread of COVID-19. Spine surgeons should collaborate with infection control specialists to avoid cross-infection in hospitals and optimize treatment.
ABSTRACT
OBJECTIVE@#To study the inhibitory effect of pills (BJJ) agaisnt diethylnitrosamine (DEN)-induced hepatocarcinogenesis and explore the relation between this effect and the inflammasome signaling pathway.@*METHODS@#Sixty-five male SD rats were randomly divided into control group, DEN model group, and 3 BJJ treatment groups at low, medium and high dose (with daily dose of 0.55, 1.1 and 2.2 g/kg, respectively, for 12 consecutive weeks starting from the 5th week after modeling). The pathological changes of the liver tissue were observed with HE and Masson staining, and serum levels of alanine transaminase (ALT), glutamic oxaloacetic transaminase (AST), alkaline phosphatase (ALP) and total bilirubin (TBIL) of the rats were detected using ELISA. Oxidation stress in the liver tissue was assessed with ELISA, and Western blotting and ELISA were used to detect the molecular expressions of inflammasome-related pathway.@*RESULTS@#BJJ significantly inhibited tumor growth in the liver of the rats. HE and Masson staining showed that BJJ treatment obviously ameliorated liver fibrosis and reduced cancer cell and inflammatory cell infiltration in the liver. BJJ significantly reduced elevations of serum ALT, AST, ALP and TBIL levels, increased the contents of superoxide dismutase, catalase and glutathione peroxidase in the liver and suppressed malondialdehyde in Den-treated rats. BJJ also dose-dependently decreased the expressions of NLRP3, apoptosis-associated speck-like protein (ASC), caspase-1, pro-IL-1β, pro-IL-18, IL-1β and IL-18 in the liver of Den-treated rats.@*CONCLUSIONS@#BJJ treatment can dose-dependently inhibit DEN-induced hepatocarcinogenesis by enhancing antioxidant capacity and down-regulating inflammatory-related pathways in rats.

Depression is a major mood disorder. Abnormal expression of glial glutamate transporter-1 (GLT-1) is associated with depression. Schisantherin B (STB) is one bioactive of lignans isolated from Schisandra chinensis (Turcz.) Baill which has been commonly used as a traditional herbal medicine for thousands of years. This paper was designed to investigate the effects of STB on depressive mice induced by forced swimming test (FST). Additionally, we also assessed the impairment of FST on cognitive function in mice with different ages. FST and open field test (OFT) were used for assessing depressive symptoms, and Y-maze was used for evaluating cognition processes. Our study showed that STB acting as an antidepressant, which increased GLT-1 levels by promoting PI3K/AKT/mTOR pathway. Although the damage is reversible, short-term learning and memory impairment caused by FST test is more serious in the aged mice, and STB also exerts cognition improvement ability in the meanwhile. Our findings suggested that STB might be a promising therapeutic agent of depression by regulating the GLT-1 restoration as well as activating PI3K/AKT/mTOR pathway.

ABSTRACT
Objective To investigate the impact of various distribution of bone cement on the early clinical outcomes in osteoporotic vertebral compression fracture (OVCF) patients treated with percutaneous kyphoplasty (PKP).Methods A total of 312 patients (54 males and 258 females,mean age 69.37 years) who diagnosed as OVCF and received PKP treatment from January 2015 to July 2017 were enrolled in the present study.All subjects were divided into two groups according to different distribution of bone cement:the shaped "O" distribution (group O,113 cases),in which bone cement in the vertebral body presented whole crumb,no separation or loss of bone cement,and the shaped "H" distribution (group H,199 cases),in which bone cement in the vertebral body presented two briquettes,connected with or without a small amount of bone cement.Demographic data,surgical details,radiographic data,and clinical outcomes (at preoperatively,two-days and one-year follow-up) were compared between the two groups.Results There was no significant difference in bone mineral density (BMD),operation duration,blood loss,and occurrence of leakage of bone cement between two groups.In comparison with group O,group H was accompanied with higher volume of injected bone cement and higher proportion of bilateral approach (P＜0.05).Both groups achieved significant improvement of VAS scores after surgery,while the group H had a dramatical reduction of VAS scores at one-year follow-up compared with two-days follow-up (P＜0.05).In addition,group H had a better restoration of VAS scores at one-year follow-up than group O (P＜0.05),though no significant difference was observed at preoperative and two-days follow-up.Both groups achieved significant improvement of radiographic data after surgery (P＜0.05) with similar effects of correction.Conclusion Either shaped "H" or shaped"O" distribution of bone cement can obtain satisfied early clinical effects of PKP for the treatment of OVCF.Compared with shaped "O" distribution,shaped "H" distribution can achieve better pain relief at early follow-up.
ABSTRACT
Bone cement-augmented pedicle screw system demonstrates great efficacy in spinal disease treatments. However, the intrinsic drawbacks associated with clinically used polymethylmethacrylate (PMMA) cement demands for new bone cement formulations. On the basis of our previous studies, a novel injectable and biodegradable calcium phosphate-based nanocomposite (CPN) for the augmentation of pedicle screw fixation was systematically evaluated for its surgical feasibility and biomechanical performance by simulated and animal osteoporotic bone models, and the results were compared with those of clinical PMMA cement. ASTM-standard solid foam and open-cell foam models and decalcified sheep vertebra models were employed to evaluate the augmentation effects of CPN on bone tissue and on the cement-injected cannulated pedicle screws (CICPs) placed in osteoporotic bone. Surgical factors in CICPs application, such as injection force, tapping technique, screw diameter, and pedicle screw loosening scenarios, were studied in comparison with those in PMMA. When directly injected to the solid foam model, CPN revealed an identical augmentation effect to that of PMMA, as shown by the similar compressive strengths (0.73 ± 0.04 MPa for CPN group vs. 0.79 ± 0.02 MPa for PMMA group). The average injection force of CPN at approximately 40-50 N was higher than that of PMMA at approximately 20 N. Although both values are acceptable to surgeons, CPN revealed a more consistent injection force pattern than did PMMA. The dispersing and anti-pullout ability of CPN were not affected by the surgical factors of tapping technique and screw diameter. The axial pullout strength of CPN evaluated by the decalcified sheep vertebra model revealed a similar augmentation level as that of PMMA (1351.6 ± 324.2 N for CPN vs. 1459.7 ± 304.4 N for PMMA). The promising results of CPN clearly suggest its potential for replacing PMMA in CICPs augmentation application and the benefits of further study and development for clinical uses.

ABSTRACT
Objective To explore the impacts of clinical pulmonary infection score (CPIS) on duration and defined daily doses (DDDs) of antibiotics in patients with bacterial severe pneumonia in intensive care unit (ICU). Methods Patients with severe pneumonia, whose antibiotic usage was prescribed with the guide of CPIS, and admitted to ICU severe respiratory and infectious disease ward of Guizhou Medical University Affiliated Hospital from May 2017 to October 2017 were enrolled as CPIS group. Patients with the first CPIS score > 5 were given antimicrobial therapy, and the score was dynamically evaluated every 2-3 days. If the CPIS score < 5, the score was evaluated again after 2 days. If the score was still < 5, the antimicrobial drugs were discontinued. Patients admitted to the same ward from November 2016 to April 2017 were regarded as controls, of whom the antibiotic usage was completely conducted by the clinical experience of the chief physician. The duration and DDDs of antibiotics were compared between patients in two groups. At the same time, the usage of ventilator and prognostic indicators (the length of ICU stay, ICU mortality) were recorded. Kaplan-Meier survival curve was drawn, and the cumulative survival rates of 28 days, 90 days and 12 months were analyzed and compared between the two groups. Results In our department, 177 and 182 patients were admitted to ICU from November 2016 to April 2017 and from May 2017 to October 2017, respectively, of whom 101 and 65 patients with severe pneumonia were collected respectively during the two stages. There was no significant difference in gender composition, age, underlying diseases, vital signs, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, or peripheral blood routine at admission between the two groups, indicating that the baseline data of the two groups were equally comparable. During the treatment process, there was no significant difference in the duration of mechanical ventilation [hours: 126.0 (69.0, 228.8) vs. 120.0 (72.0, 192.0)], the length of ICU stay [days: 7.0 (5.0, 11.0) vs. 8.0 (5.0, 14.0)], or ICU mortality [18.8% (19/101) vs. 26.2% (17/65)] between the control group and CPIS group (all P >0.05). Kaplan-Meier survival curve analysis showed that there was no significant difference in the cumulative survival rate of 28 days (log-rank test: χ2 = 0.540, P = 0.462), 90 days (log-rank test: χ2 = 0.332, P = 0.564) or 12 months (log-rank test: χ2 = 0.833, P = 0.362). Patients from CPIS guided group, however, had a shorter duration of antibiotics usage (days: 7.54±4.81 vs. 9.88±4.96, P < 0.01), and had a lower DDDs of antibiotics (17.58±13.09 vs. 22.73±18.31, P < 0.05) as compared with those in the control group. Conclusion CPIS-guided therapeutic regimen shortens antibiotic duration and decreases antibiotic DDDs in patients with severe pneumonia in ICU, indicating the values of CPIS in guiding antibiotics usage in these patients.
ABSTRACT
BACKGROUND: Kyphoplasty with bone cement injection for the treatment of osteoporotic vertebral compression fractures has a good clinical effect, but it is unclear whether there is a difference in the efficacy on the fractures in different parts of the spine. OBJECTIVE: To compare the outcomes of kyphoplasty with bone cement injection in the treatment of osteoporotic vertebral compression fractures in different parts of the spine. METHODS: We retrospectively analyzed the clinical data of 247 cases of single-segmental osteoporotic vertebral compression fractures undergoing kyphoplasty with bone cement injection at the Department of Orthopaedic Surgery, the First Affiliated Hospital of Soochow University in China from January 2011 to August 2014. There were 24 cases of upper and middle thoracic (T1-T10) fractures, 187 cases of thoracolumbar (T11-L2) fractures and 36 cases of lower lumbar (L3-L5) fractures. The surgical time, X-ray exposure time, bone cement volume and leakage, the Visual Analog Scale score, the Oswestry Disability Index score, anterior vertebral height ratio and Cobb angle were assessed preoperatively, at 1 day posteroperatively and at the final visit. RESULTS AND CONCLUSION: (1) All patients underwent the surgery successfully, and were followed up for 12-44 months, with an average of (25.44±7.85) months. (2) There were 18 cases of bone cement leakage in the three groups, including 3 (12.5％) cases of upper and middle thoracic fractures, 13 (6.4％) cases of thoracolumbar fractures and 2 (5.6％) cases of lower lumbar fractures. (3) The surgical time and X-ray exposure time were significantly higher in the patients with upper and middle thoracic fractures than those with thoracolumbar fractures or lower lumbar fractures (P < 0.05) , while the volume of bone cement was significantly lower than that in the other two groups (P < 0.05) . Additionally, there were no significant differences in the surgical time, X-ray exposure time, and amount of bone cement between the patients with thoracolumbar fractures and with lower lumbar fractures (P> 0.05) . (4) There were no significant differences in the Visual Analog Scale score, Oswestry Disability Index score, anterior vertebral height ratio and Cobb angle among the three groups preoperatively, at 1 day postoperatively and at the final visit (all P> 0.05) . However, compared with baseline, these indicators were significantly improved in each group at 1 day postoperatively and at the final visit (P < 0.05) . (5) To conclude, kyphoplasty with bone cement injection has achieved satisfactory outcomes in the treatment of osteoporotic vertebral compression fractures in different parts of the spine.

Objective To evaluate the clinical application of early total care (ETC) for polytrauma patients combined with thoracolumbar fractures.Methods A retrospective case control study was conducted to analyze the clinical data of 137 polytrauma patients combined with thoracolumbar fractures admitted to the First Affiliated Hospital of Soochow University and the Third People's Hospital of Zhang,jiagang from January 2012 to October 2015.There were 90 males and 47 females,aged 26-69 years,with an average age of 48.2 years.The patients were divided into ETC group (n =59) and TMC group (n =78).In the ETC group,physicians from different departments evaluated the patients and developed individualized therapeutic regimens to allow the patients to undergo surgery at early stage after injury.The TMC group preferentially stabilized the patient's condition or transferred the patients to specialist treatment,and then the surgery was performed electively after the condition of the patient was stable.The ISS of the ETC group was (22.15 ± 9.28)points,and that of the TMC group was (23.37 ± 10.74) points.All patients underwent conventional posterior pedicle screw internal fixation.For patients with burst fracture and nerve injury,posterior spinal canal decompression was performed.The thoracolumbar injury classification and severity score (TLICS),spinal load sharing classification (LSC),preoperative and postoperative Glasgow coma score (GCS),Frankel classification,hospitalization time and postoperative complications were compared between the two groups.Results The TLICS scores of ETC group were significantly lower than those of TMC group (P ＜ 0.05) while the LSC scores showed no significant differences between the two groups (P ＞ 0.05).ETC group had shorter hospitalization time [(11.8 ± 3.7)days ∶ (17.5 ±4.5)days] and lower pressure ulcer incidence [(5％ ∶ 21％)] than the TMC group (P ＜ 0.05 or 0.01),but the former had significantly higher wound infection rate [(17％ ∶ 15％)] (P ＜ 0.05).There was no significant difference in pulmonary infection and deep venous thrombosis incidence between the two groups (P ＞ 0.05).No significant differences were found in the preoperative GCS scores between the two group (P ＞ 0.05) while the postoperative GCS scores of TMC group were higher than those of ETC group (P ＜ 0.01).Postoperative GCS scores in both groups were significantly higher than their preoperative GCS (P ＜ 0.05).The results of postoperative Frankel classification in the ETC group were as follows:Grade A in one patient,Grade B in one,Grade C in three,Grade D in four and Grade E in two patients,with an improvement rate of 82％.The results of postoperative Frankel classification in the TMC group were as follows:Grade A in three patients,Grade B in three,Grade C in three,Grade D in four and Grade E in four,with an improvement rate of 65％.Conclusions For polytrauma patients combined with thoracolumbar fractures,ETC can shorten hospitalization time,reduce the pressure ulcer incidence,and better facilitate the recovery of nerve function,yet with higher wound infection risk compared with TMC.TMC was preferred subjectively for patients with unstable thoracolumbar fractures and high TLICS.
ABSTRACT
Objective To study the morbidity,pathogenesis,diagnosis and treatment of winged scapula.Methods The key words about "winged scapula" have been used to search articles which include winged scapula patients in English and Chinese literature databases from 1958 to 2017.The articles have been filtrated by title,abstract and full text.There are 36 articles used for this study.All the patients are objects of this study,but the same patients' data in different articles have not been used repeatedly.The patients' data have been collected as much as possible,including age,sex,causes,treatment,follow-up and so on.All the patients' data have been used for systematic analysis.Results All of 356 patients with winged scapula were selected from 36 literatures for systematic analysis.There were 213 cases of anterior saw muscle paralysis,among which 16 cases were physical exercise,11 cases were excellent and 5 cases were poor,with an excellent rate of 68.8％.There were 70 cases of neurolysis and transplantation,50 cases were excellent and 20 cases were poor,with an excellent rate of 71.4％.There were 3 cases of scapulectomy,1 case excellent and 2 cases poor.There were 124 cases of pectoralis major tendon metastasis,88 cases were excellent,36 cases were poor,and the excellent rate was 71％.There were 46 cases of trapezius paralysis,among which 14 cases were physical exercise,12 cases were excellent,2 cases were poor,and the excellent rate was 86％.1 case of scapulopexy and 1 case of superior,with an excellent rate of 100％;There were 31 cases of Eden-Lange 31 cases,27 cases of excellent and 4 cases of poor.One case of rhomboid myoplegia was treated,including 1 case of rehabilitation training (ultrasound guidance),1 case of excellent,with an excellent rate of 100％.There were 96 cases of muscular dystrophy,including 96 cases of scapulectomy,76 cases of excellent and 20 cases of poor,with an excellent rate of 79.1％.Conclusion Winged scapula is rare and its incidence is unknown,different causes determine different treatments:Anterior saw muscle palsy is more suitable for thoracolumbar tendon transfer,and modified Eden-Lange is more suitable for trapezius palsy.
ABSTRACT
Objective To evaluate the clinical effects of minimally invasive percutaneous new C2transpedicular lag-screw fixation for management of Hangman's fractures.Methods From October 2015 to June 2017,25 patients who had Hang-man's fracture were operated with minimally invasive percutaneous new C2transpedicular lag-screw fixation assisted by infrared navigation,among them there were 18 male and 7 female,aged from 28 to 70 years[average(46.1±13.3)years].According to the Levine-Edwards classification:16 patients were TypeⅠ,6 patients were TypeⅡand 3 patients were TypeⅡA.The cause of the in-jury was road traffic accident in 20 patients and fall from height in 5 patients.19 patients were simple Hangman's fracture and oth-er associated lesions included odontoid fracture of TypeⅡ(2 patients),atlas fracture of TypeⅠ(2 patients),rupture of spleen(1 pa-tient),and rib fractures(1 patient).According to American Association for spinal cord injury,graded as spinal cord injury D in 3 cases and E in 22 cases.The clinical outcomes were evaluated by visual analog scale(VAS)scores and related indicators,such as operation time,the range of motion(ROM)of cervical spine and ratio of bony union were recorded.The pre-and post-operative VAS scores of neck pain were compared with repeated measures analysis of variance. Results The mean follow-up time was (12.5±6.0)months,ranging from 3 to 24 months.Satisfactory reduction was obtained in all cases(minimal translation≤2 mm with-out obvious C2,3angulation).The average operation time was(65.9±12.1)min.At first day,one month,three months and the last fol-low-up, VAS scores of neck pain decreased comparing with preoperational measurements. There was significant difference be-tween the pre-and post-operative VAS scores of neck pain(t=24.7,25.8,23.1,24.1,P<0.001).According to American Associa-tion for spinal cord injury,three cases restored from D to E.There was no spinal cord or vertebral artery injury during operation and there was no screw loosing or breakage and cervical malformation happened during follow-up period. Bony fusion was achieved in all of these cases and the range of neck rotation was stored normal at the last follow-up.The average time of Bony fu-sion was(3.4±0.8)months.Conclusion The primary clinical efficacies of minimally invasive percutaneous new C2transpedicu-lar lag-screw fixation for treatment of Hangman's fracture were satisfactory,which carries precision and safety,immediate stability and more reliable.So it could be considered as a new choice for management of Hangman's fractures.
ABSTRACT
Objective To investigate the risk factors affecting Sandwich vertebral re-fracture after vertebral augmentation surgery for osteoporotic spine Sandwich fractures.Methods A retrospective case control study was conducted on the clinical data of 90 patients with osteoporotic spine Sandwich fractures treated with vertebral augmentation surgery from January 2004 to December 2015.There were 26 males and 64 females,aged (69.9 ± 7.4) years.The patients were divided into fracture group (n =15) and non fracture group (n =75) according to the incidence of re-fracture after operation during follow-up.Gender,age,height,weight,bone mineral density,cumulative number of cemented vertebrae,location of the Sandwich vertebrae in the thoracolumbar segment,the preoperative kyphosis angle of the Sandwich fracture segment,surgical approach,cement injection approach (unilateral or bilateral),cement injection volume,cement leakage between the Sandwich intervertebral spaces,the postoperative kyphosis angle of the Sandwich fracture segment,and follow-up duration were used as independent variables.Chi-square test and multivariate logistic regression analysis were used to analyze the risk factors of vertebral Sandwich fracture.Results There were 97 Sandwich vertebrae in 90 patients,and 226 fractured vertebrae were treated with initial intensive treatment.The mean follow-up was 18.1 months.There were no significant differences in gender,age,height,weight,cumulative number of cemented vertebrae,whether the Sandwich vertebrae was located at the thoracolumbar segment,the preoperative kyphosis angle of the Sandwich fracture segment,the cement injection approach (unilateral or bilateral),the volume of cement injection,and the cement leakage between the Sandwich intervertebral spaces (P ＞ 0.05).There were significant differences in bone mineral density,surgical approach,and postoperative kyphosis angle of the Sandwich fracture segment between the two groups (P ＜ 0.05).Further logistic regression analysis showed that bone mineral density ≤ 3.5 SD and segmental kyphosis (≥ 10°) were risk factors for Sandwich fracture (P ＜ 0.05).Conclusions The low bone mineral density (T value ≤-3.5 SD) and postoperative kyphotic angle (≥ 10°) are risk factors for re-fracture of Sandwich vertebrae.Vertebroplasty itself does not increase the risk of recurrent vertebral fractures.
ABSTRACT
Endometriosis is a common benign disease of Gynecology, which often causes symptoms of dysmenorrhea, pelvic pain and infertility. In this paper, we analyzed the effect of laparoscopy combined with mifepristone in the treatment of endometriosis. By observing the clinical efficacy and side effects of small dose mifepristone, we explored the feasibility of small dose mifepristone in the treatment of recurrent endometriosis. The results showed that the clinical symptoms of small dose mifepristone group and danazol group were improved to varying degrees. The improvement rate of mifepristone group was 96.7% for dysmenorrhea and 61.1% for non menstrual lower abdominal pain, respectively. In conclusion, small dose mifepristone is an effective treatment for recurrent endometriosis with high remission and good curative effect
ABSTRACT
Objective To compare the radiographic and clinical outcomes of uniaxial and polyaxial locking plates used in the treatment of complex intraarticular calcaneal fractures.Methods A retrospective comparative study was performed on the 50 patients with intraarticular calcaneal fracture (Sanders types Ⅲ and Ⅳ) who had been treated by uniaxial locking plates (n =26) or polyaxial locking plates (n =24) between January 2013 and June 2015.Operation time,intraoperative bleeding,union time,radiological and functional outcomes and functions by the Maryland foot score were compared between the 2 groups.Results All the patients were followed up for 12 to 44 months(average,20.8 months).There were no significant differences between the 2 groups in average operation time (105.2 ± 18.2 min versus 95.5 ± 17.7 min),average intraoperative bleeding (125.2 ±23.4 mL versus 120.3 ±21.5 mL),or union time (12.1 ± 3.7 weeks versus 11.8 ± 3.7 weeks) (P ＞ 0.05).All patients obtained bony union.The polyaxial locking plates group displayed significantly better B(o)hler and Gissane angles at 3 and 12 months after operation than the uniaxial locking plates group (P ＜ 0.05).Evaluated by the Maryland foot score,the excellent and good rate for the polyaxial locking plates group [91.7％ (22/24)] was insignificantly higher than that for the uniaxial locking plates group [84.6％ (22/26)] (P =0.267).Conclusions Both uniaxial locking and polyaxial locking plates can lead to satisfactory therapeutic outcomes for complex intraarticular calcaneal fractures,but polyaxial locking plates may be superior in stability and functional recovery.
