Objective To summarize the clinical efficacy of suture anchors in repairing the delayed Achilles tendon rupture.Methods From January 2010 to December 2013,23 patients with delayed Achilles tendon rupture were treated using the suture anchors.There were 19 males and 4 females,at mean age of 43 years (range,35-53 years).Injury on the left side occurred in 5 patients and right side in 18 patients.Mean time from injury to operation was 26.3 days (range,21-40 days).Ten patients were diaguosed by ultrasound and the other by MRI.All patients underwent suture anchor fixation without external support.Functional training started at the early stage.Incision complications were detected.Ankle flextiou-extension range,American Orthopedic Foot and Ankle Society (AOFAS) score,maximum bilateral leg circumference,tendon rerupture and walking posture were recorded at postoperative 6,12,18 and 24 months.Achilles tendon muscular strength was measured with the Lunsford-Perry heelrise test.Results Follow-up was 24 months.All incisions healed by first intention without sural nerve injury,adherence with skin and deep infection.Six months after operation,the ankle range of motion was dorsiflexion 10.8° (range,9-15°) and plantar flexion 43.8° (range,40-48°),with no significant difference in comparison to the health side (P ＞ 0.05).AOFAS score differed significantly before and after operation (P ＜ 0.01).Maximal leg circumference was 38.2 cm in the health side versus 35.8 cm in the injury side (P ＜ 0.05),but the difference was no more than 3 cm.All patients completed 25 times heel raising without difficulty.Four patients walked with a slight limp and recovered from the limp 12 months after operation.No Achilles tendon ruptured again during the follow-up time.Conclusions Repairing the old Achilles tendon rupture with suture anchors can supply strongly strain between broken ends of the tendon,and the outer cast is not needed after operation.Complications are less and functional practice can be commenced in the early postoperative period for better function restoration.

Objective To study the clinical value of acoustic radiation force impulse imaging (ARFI) in patients with ischemic type biliary lesion (ITBL) after orthotopic liver transplantation. Methods Between July 2012 to January 2013, forty-one patients in General Hospital of the People′s Liberation Army were enrolled in this study who were admitted for post-transplantation follow-up. Among them, 15 patients were diagnosed as ITBL by ultrasonography. Besides conventional ultrasonography, ARFI was used to detect the shear wave velocity (SWV) of liver tissue at depth of 4 cm and 5 cm respectively. Simultaneously liver function test was performed. Independent-samples t test was performed to compare the difference of SWV between ITBL and non-ITBL group at the same depth. Paired-sample t test was performed to compare the difference of SWV for the same ITBL patient. Pearson correlation analysis was used in analyzing the relation between SWV and liver function. Results The average SWV in depth of 4 cm was (1.561±0.425) m/s and (1.121±0.160) m/s in ITBL and non-ITBL group, respectively. Signiifcant differences were found among the ITBL and non-ITBL groups (t=-3.173, P=0.01). The average SWV in depth of 5 cm was (1.608±0.545) m/s and (1.175±0.173) m/s in ITBL and non-ITBL group, respectively. Signiifcant differences were found among the ITBL and non-ITBL groups (t=-2.454, P=0.034). There was no signiifcant difference between SWV measurements at different depth for the same ITBL patient. For all patients, SWV at different depths were both strongly correlated with alkaline phosphatase (r=0.656, 0.667, respectively;both P=0.000) andγ-glutamyl transpeptidase (r=0.482, P=0.007;r=0.508, P=0.004). Conclusion The liver stiffness measurement is valuable for the clinical evaluation of post-transplantation ITBL.

Objective:To study the clinical effect of internal combined with external fixation in the treatment of pelvic fracture and its effect on the serum alkaline phosphatase (ALP),tumor necrosis factor-a (TNF-α) and transforming growth factor-β (TGF-β).Methods:Eighty-six patients with pelvic fractures admitted in our hospital from August 2014 to July 2015 were selected and divided into the observation group and control group according to the admission order.Conventional internal fixation was used in the control group,and the internal combined with extemal fixation was performed in the observation group.The clinical curative effect,operative time,blood loss,fracture healing time and incidence of complication were compared between two groups.The levels of serum ALP,TNF-α and TGF-β in the two groups were compared before and after treatment between two groups.Results:The excellent rate of observation group was significantly higher than that of the control group [81.40％ (35/43) vs 41.86％ (18/43)] (P ＜0.05).The operative time,blood loss and fracture healing time in the observation group were significantly shorter or less than those of the control group (P＜0.05).There was no significant difference in the serum ALP,TNF-α and TGF-β levels between the two groups before treatment (P＞0.05).After treatment,the serum ALP levels in the two groups were significantly higher than before treatment (P＜0.05).The levels of TNF-α and TGF-β were significantly lowe than those before treatment(P＜0.05),the ALP levels in the observation group was significantly higher than that of the control group (P ＜0.05),and the levels of TNF-c and TGF-β were significantly lower than those of the control group 0.05).The incidence of complications of observation group was significantly lower than that of the control group [0.00％ (0/43) vs 11.63％ (5/43)] (P ＜0.05).Conclusion:Internal and external fixation was effective and safe in the treatment of pelvic fractures,which could significantly increase the serum ALP level and reduce the levels of TNF-α and TGF-β.

Objective To investigate the related factors of the prognosis of arterial embolectomy of acute cardiogenic cerebral embolism caused by atrial fibrillation.Methods The clinical data of using vein thrombolysis bridging artery embolectomy or arterial embolectomy alone for the treatment of patients with acute cardiogenic cerebral embolism of cerebral large artery occlusion due to atrial fibrillation were analyzed retrospectively.From January 2015 to December 2016,22 consecutive inpatients with cardioembolic cerebral embolism caused by paroxysmal or persistent atrial fibrillation were enrolled,including 10 patients with the 90-day modified Rankin Scale (mRS) score 0-2 (good recovery group) and 12 patients with mRS scores 3-6 (poor recovery group).The clinical features,imaging data,and treatment of the patients in both groups were compared.The factors such as age,gender,preoperative international standardization ratio (INR),embolism position,whether bridging vein thrombolysis before thrombectomy,National Institutes of Health Stroke Scale (NIHSS) score at the onset,time of onset to reperfusion (TOR),whether using tirofiban,times of thrombectomy,modified Thrombolysis In Cerebral Infarction (mTICI) blood flow grade,and postoperative intracranial symptomatic intracerebral hemorrhage were analyzed.Results There were no significant differences in age,gender,preoperative INR,embolism position,the number of intravenous thrombolysis before thrombectomy,the number of using tirofiban in surgery,the proportion of the above mTICI 2b grade,and the proportion of symptomatic cerebral hemorrhage after surgery of the patients between the two groups (P>0.05).The NIHSS score 15.2±2.0 at the onset in the good recovery group was lower than 22.9±8.4 in the poor recovery group.There was significant difference between the two groups (P<0.05).The TOR time (307±86 min) in the good recovery group was less than that of the poor recovery group (426±145 min).There was significant difference between the two groups (P<0.05).Embolectomy was performed 1.5 (0.5,3.0) times in the good recovery group,which was less than the poor recovery group (4.0 [2.0,7.0] times).There was significant difference between the two groups (P<0.05).Conclusions Shortening the time of reperfusion and reducing the number of embolectomy during operation are the important factors for improving the prognosis of patients when atrial fibrillation causes arterial embolectomy in patients with acute cerebral embolism.However,a study of larger sample is needed for further exploration.

The number of the patients with double primary cancers is increasing. Breast cancer and lung cancer are the two most common malignant tumors in women, seriously threatening the health of the majority of women. Although the lung is one of the most common metastatic sites of breast cancer, in recent years, there have been increasing cases of primary lung cancer in patients with breast cancer. The incidence of double primary cancers with breast cancer as the first primary cancer is much higher than that with lung cancer as the first primary cancer. Primary breast cancer is closely related to the occurrence and development of lung cancer. This article reviews the epidemiology, clinicopathological features, diagnosis and treatment of double primary breast cancer and lung cancer with breast cancer as the first cancer.

Objectives To analyze the links of the in-hospital delay by investigating the status of in-hospital delay in patients with acute ischemic stroke in a tertiary hospital in Beijing and to shorten the in-hospital delay by intervention. Methods From August 2016 to July 2017,98 patients with ischemic stroke treated by endovascular therapy and met the inclusion criteria in the Xuanwu Hospital, Capital Medical University were collected prospectively. According to before and after intervention,the patients were divided into before intervention (from August 2016 to January 2017,n=44) and after intervention (from February to July 2017,n=54). The questionnaire was designed by the authors. The survey included the basic information of patients,clinical features,and key time point of hospital treatment process. The delay links were analyzed through the value flow diagram,and the targeted interventions were given to shorten the time of in-hospital delay. Results (1) The main links of the presence of in-hospital delay are physician evaluation,disease notification, signing of the informed consent, and preoperative preparation. ( 2 ) The intervention effect was significant. The median total nosocomial process time before and after intervention were 138. 0 (118. 5,188. 8) min and 93. 5 (80. 0,114. 0) min respectively. There was significant difference(Z=5. 929,P<0. 01). Compared with before intervention,the time of examination,imaging examination, preoperative preparation and femoral artery puncture were shorter ( 16. 5 [ 10. 0, 27. 2 ] min vs. 35. 0 [18. 2,51. 8] min;10. 0 [9. 0,11. 0] min vs. 12. 5 [10. 0,23. 8] min;48. 0 [30. 0,67. 5] min vs. 60. 5 [45. 5,90. 8] min;15. 0 [12. 0,18. 2] min vs. 21. 0 [13. 0,33. 0] min,Z=4. 150,3. 685,2. 801,and 2. 852,respectively;all P<0. 05). Conclusions The nosocomial process of endovascular treatment in patients with ischemic stroke is seriously delayed. Through continuous improvement of the nosocomial process,setting up a parallel treatment modality,strengthening the stroke team training,and improving the docking measures of the information system platform can significantly shorten the in-hospital time.

OBJECTIVETo investigate the causes and strategy of difficult intraarterial mechanical thrombectomy (≥3 times) in patients with acute ischemic stroke (AIS).

METHODSThe clinical data of 8 cases of AIS with thrombectomy ≥3 times admitted in Department of Neurology, the 306(th) Hospital of People's Liberation Army from June to October in 2015 was analyzed retrospectively. There were 7 male and 1 female patients, aged from 38 to 86 years with an average age of (70±15) years, in which 5 cases were cardiogenic cerebral embolism and 3 cases were large artery atherosclerotic infarction. The National Institute of Health stroke scale (NIHSS) score (M (QR)) was 16 (12) before procedure and modified thrombolysis in cerebral infarction (mTICI)score were 0 in all the patients. Solitaire AB was used in thrombectomy in the occlusion of the arteries.

RESULTSThe causes of difficult intraarterial thrombectomy included multiple thrombus, tortuosity in vascular paths, guiding catheter being placed below the internal carotid artery siphon leading to weak strength of suction and support of stent, embolus dropping in the thrombectomy and inadequate anesthesia. After successful thrombectomy 3 cases had mTICI score of 2a, 4 cases of 2b, 1 case of 3. The NIHSS score was 5 (24) at 7(th) day after treatment. At the 90-day follow-up 5 patients had good prognosis (modified Rankin score 0 to 2) and 3 had disability (modified Rankin score 3 to 4).

CONCLUSIONCases of AIS with difficult intraarterial thrombectomy can be treated by improving thrombectomy materials and technique, reasonable anesthesia and perioperative medication in decision-making strategy.

With the research progress on the biology and pathogenesis of cancer, immune checkpoint inhibitors (ICIs) have come into being, bringing a new hope for the survival of patients with advanced cancer and opening a new era of cancer immunotherapy. However, with the wide application of immunotherapy in clinical practice, ICI-related adverse events (irAEs) have gradually emerged and are widely known by first-line clinicians. ICIs primarily activate T cells that can attack normal tissues and organs in the body and cause a variety of adverse reactions. Checkpoint inhibitor pneumonitis (CIP) is one of the rare complications with poor prognosis in irAEs. This article reviews the therapeutic mechanism of some ICIs; the incidence, risk factors, pathogenesis, and clinical and imaging manifestations of CIP; and the classification and treatment management of CIP.

Patient-based real-time QC (PBRTQC) uses patient-derived data to assess assay performance. PBRTQC algorithms have advanced in parallel with developments in computer science and the increased availability of more powerful computers. The uptake of Artificial Intelligence in PBRTQC has been rapid, with many stated advantages over conventional approaches. However, until this review, there has been no critical comparison of these. The PBRTQC algorithms based on moving averages, regression-adjusted real-time QC, neural networks and anomaly detection are described and contrasted. As Artificial Intelligence tools become more available to laboratories, user-friendly and computationally efficient, the major disadvantages, such as complexity and the need for high computing resources, are reduced and become attractive to implement in PBRTQC applications.
