ABSTRACT
Objective:To investigate the value of ultrasound findings in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus and correlate it with clinical factors.Methods:A total of 535 patients with type 2 diabetes mellitus who received treatment in Taiyuan Second People's Hospital from January 2016 to June 2019 underwent color Doppler ultrasound examination (T2DM group). Vascular inner diameter, intima-media thickness, atherosclerotic plaque formation, lumen stenosis or occlusion, and hemodynamic characteristics were determined in patients with type2 diabetes mellitus compared with those in 107 patients with non-type 2 diabetes mellitus (non-T2DM group). These parameters were correlated with the course of the disease, blood glucose level, concomitant hypertension or not, and clinical Wagner grade.Results:The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were 69.9%, 89.0%, 77.0% and 11.6% respectively, in the T2DM group, which were significantly higher than 41.1%, 78.5%, 72.0%, and 1.9% respectively in the non-T2DM group ( χ2 = 32.52, P < 0.001; χ2 = 8.76, P = 0.003; χ2 = 27.77, P < 0.001). With the prolongation of the course of T2DM, the incidence of arterial lesions in the lower extremities increased ( P < 0.001). The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were significantly greater in the poor blood glucose control group and non-hypertension group compared with the good blood glucose control group and hypertension group (all P < 0.05). The degree of lower extremity arterial stenosis in T2DM patients was related to Wagner's grade. As the degree of stenosis increased, Wagner's grade increased correspondingly and significantly ( P < 0.001). Conclusion:Color Doppler ultrasound examination has an important value in evaluating lower extremity arterial lesions in patients with T2DM. The degree of arterial lesions in the lower extremities of T2DM patients is correlated with the course of the disease, blood glucose levels, concomitant hypertension, and clinical Wagner grade. Color Doppler ultrasound examination has an important clinical significance in evaluating the degree of vascular lesions and guiding early interventions in the clinic.
ABSTRACT
Achalasia is a primary esophageal motility disorder manifested by dysphagia and chest pain that impair patients’ quality of life, and it also leads to chronic esophageal inflammation by food retention and increases the risk of esophageal cancer. Although achalasia has long been reported, the epidemiology, diagnosis and treatment of achalasia are not fully understood. The current clinical dilemma of achalasia is mainly due to its unclear pathogenesis. In this paper, epidemiology, diagnosis treatment, as well as possible pathogenesis of achalasia will be reviewed and summarized. The proposed hypothesis on the pathogenesis of achalasia is that genetically susceptible populations potentially have a higher risk of infection with viruses, triggering autoimmune and inflammation responses to inhibitory neurons in lower esophageal sphincter.
ABSTRACT
ObjectiveTo evaluate the efficacy and safety of a perioperative rehabilitation clinical pathway of acetabular fracture in light of orthopedics rehabilitation team approach. MethodsA prospective randomized control trial was conducted in 82 patients with acetabular fractures who had been admitted from the Emergency Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from June, 2019 to January, 2021. The patients were randomly divided into control group (n = 41) and intervention group (n = 41). The control group was managed routinely, while the intervention group received the rehabilitation clinical pathway, for 24 weeks. The Visual Analogue Score (VAS) of pain, the Barthel Index (BI) and Majeed Pelvic Score were compared. ResultsFinally, 76 patients completed the trial. There was no statistical difference in VAS score between two groups in all periods (|Z| < 1.926, P > 0.05). The BI score was higher in the intervention group than in the control group at discharge, two weeks, six weeks and twelve weeks after operation (|Z| > 2.121, P < 0.05); and no significant difference was found before operation and 24 weeks after operation (|Z| < 1.862, P > 0.05). Majeed Pelvic Score was higher in the intervention group than in the control group two weeks, six weeks, twelve weeks and 24 weeks after operation (|Z| > 2.428, P < 0.05). Six, twelve and 24 weeks after operation, the excellent rate of Majeed Pelvic Score was higher in the intervention group than in the control group (χ2 > 6.136, P < 0.05). ConclusionIn comparison with traditional protocol in acetabular fracture, the perioperative rehabilitation clinical pathway was proved effective and of great safety in the light of the integration of orthopedics and rehabilitation mode for improving the function and activities of daily living of patients.
ABSTRACT
Objective:To analyze the clinical efficacy and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH-a) based fertility-sparing re-treatment in women with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) who failed with oral progestin therapy.Methods:Forty cases with EC or AEH who failed to respond to oral progestin were included from January 2012 to December 2020 at Peking Union Medical College Hospital. Combination of GnRH-a with levonorgestrel-releasing intrauterine system (group GLI: a subcutaneous injection of GnRH-a every 4 weeks and LNG-IUS insertion constantly) or the combination of GnRH-a with aromatase inhibitor (group GAI: a subcutaneous injection of GnRH-a every 4 weeks and oral letrozole 2.5 mg, daily) were used for these patients. Histological evaluation were performed at the end of each course (every 3-4 months) by hysteroscopy and curettage. After the complete remission (CR), all patients were followed up regularly.Results:(1) Clinical characteristics:among the 40 patients with EC or AEH, the median age at diagnosis was 31 years (range: 22-40 years) and the median body mass index was 24.7 kg/m 2 (range: 18.9-39.5 kg/m 2). (2) Efficacy of fertility-sparing re-treatment: 37 (92%, 37/40) patients achieved CR, 6 (6/7) in AEH and 31 (94%, 31/33) in EC patients. The CR rate was 93% (26/28) and 11/12 in group GLI and GAI, respectively. The median time to CR was 5 months (range: 3-12 months). At the end of the first therapy course, the CR rates in AEH and EC were 5/7 and 42% (14/33), at the second course, the CR rates were 6/7 and 82% (27/33), respectively. (3) Recurrence: after 25 months of median follow-up duration (range: 10-75 months), 8 (22%, 8/37) women developed recurrence, 1/6 in AEH and 7 (23%, 7/31) in EC patients, with the median recurrence time of 18 months (range: 9-26 months). Among them, two cases who had completed childbirth chose to receive hysterectomy directly. Six patients met the criteria of fertility-preserving therapy and received conservative treatment again and 5 (5/6) of them achieved CR. (4) Pregnancy: of the 37 patients with CR, 33 desired to conceive. Ten women attempted to get pregnancy spontaneously and 23 cases with assisted reproductive technology. Fourteen (42%, 14/33) patients became pregnant, including 9 (27%, 9/33) live births, 3 (9%, 3/33) missed abortions, and 2 (6%, 2/33) miscarriages at the second trimester. Conclusions:GnRH-a based fertility-sparing re-treatment in AEH or EC patients who failed with oral progestin therapy achieved good treatment effect and reproductive outcomes. It is an encouraging alternative regime for patients who failed with oral progestin therapy.
ABSTRACT
Objective:To evaluate the efficacy and safety of perioperative rehabilitation approaches based on the concept of Enhanced Recovery After Surgery (ERAS) for pelvic fractures.Methods:A prospective randomized control trial was conducted to include 114 emergency patients who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital for surgical treatment of pelvic fractures from June 2019 to December 2020. Of them, 57 were assigned into an intervention group according to a random digits table. They were 42 males and 15 females, aged from 18 to 77 years and subjected to management of pelvic fractures with tentative perioperative ERAS approaches which were adjusted at different stages. The other random 57 patients were assigned into a control group. They were 40 males and 17 females, aged from 17 to 70 years and subjected to management of pelvic fractures with conventional rehabilitation approaches which included postoperative in-hospital consultation and guidance by rehabilitation physicians. The 2 groups were compared in terms of Majeed pelvis scores and Barthel indexes at postoperative 2, 6, 12 and 24 weeks, and visual analogue scale (VAS) pain scores and SF36 scores at postoperative 12 and 24 weeks.Results:A total of 105 patients (55 in the intervention group and 50 in the control group) were completely followed up for 151 to 254 d (mean, 177 d). The 2 groups were comparable due to no significant difference between them in the preoperative general data ( P>0.05). The Majeed scores (44±13, 67±16, 86±14 and 98±7) and Barthel indexes (57±13, 79±16, 95±8 and 100±2) at postoperative 2, 6, 12 and 24 weeks in the intervention group were significantly higher than those in the control group [(35±16, 51±16, 73±14 and 91±12) and (45±19, 67±18, 86±12 and 98±4)] (all P<0.05). At postoperative 12 and 24 weeks, the SF-36 scores (129±15 and 141±6) in the intervention group were significantly higher than those in the control group (114±15 and 131±12) ( P<0.05). There was no significant difference in the pain degree between the 2 groups ( P>0.05). Conclusion:In management of pelvic fractures, compared with conventional perioperative rehabilitation approaches, the perioperative ERAS rehabilitation approaches may improve early functional outcomes and thus help the patients restore their activities of daily living earlier.
ABSTRACT
Objective:To explore the expression and clinical significance of IL-1β and IL-1β receptor antagonist(IL-1ra)in persistent pulmonary hypertension of the newborn(PPHN)secondary to sepsis.Methods:The newborns with sepsis were enrolled in the Department of Neonatal Intensive Care Unit(NICU)of Xi′an Children′s Hospital from January 2018 to November 2020.The newborns with sepsis were divided into two groups: the newborns without PPHN( n=108)were the control group and the newborns with PPHN( n=44)were the experimental group.Clinical data, laboratory examination and bedside echocardiography of all the newborns were collected to analyze the differences between the two groups.The expression levels of IL-1β and IL-1ra in neonatal plasma of the two groups were detected by enzym-linked immunosorbination(ELISA), and their roles in neonatal sepsis with PPHN were further analyzed.The risk factors of neonatal sepsis with PPHN were analyzed by multivariate Logistic regression, and the early prediction value of the risk factors for neonatal sepsis with PPHN were evaluated by the receiver operating characteristic(ROC)curve. Results:There were no significant differences in gestational age[(39.11±0.55)w vs(38.85±0.72)w], birth weight[(3.30±0.49)kg vs(3.24±0.55)kg]and proportions of males[60(55.6%)vs 30(68.2%)]between the two groups( P>0.05). The right ventricular diameter[(9.57±0.35)mm], pulmonary artery pressure[(51.36±5.91)mmHg]and the level of N-terminal brain natriuretic peptide(NT-proBNP)[(25436.83±12343.18)ng/L)]significantly increased in the experimental group than those in the control group[(8.77±0.41)mm, (31.24±5.11)mmHg, (11267.09±4405.48)ng/L, respectively, P<0.05]. Before treatment, the expression levels of plasma IL-1β[(31.24±5.25)ng/L]and IL-1ra[(41.94±10.13)ng/L]in the experimental group were significantly higher than those in the control group[(18.27±4.47)ng/L, (21.47±8.76)ng/L, respectively, P<0.05]. The expression levels of plasma IL-1β[(10.46±3.17)ng/L]and IL-1ra[(10.58±2.94)ng/L]in the experimental group after treatment were significantly lower than those before treatment[(31.24±5.25)ng/L, (41.94±10.13)ng/L , respectively, P<0.05]. Multivariate Logistic regression analysis showed that IL-1β and NT-proBNP were the independent risk factors for neonatal sepsis with PPHN( P<0.05). ROC curve analysis showed that IL-1β and NT-proBNP had the good predictive value for the occurrence of neonatal sepsis with PPHN( P<0.05). IL-1β combined with NT-proBNP has the better predictive value for neonatal sepsis with PPHN. Conclusion:IL-1β combined with NT-proBNP have the high predictive value for PPHN of the newborns secondary to sepsis.
ABSTRACT
Objective:To analyze the clinical features of moderate or severe neonatal hemophilia, and improve the understanding of this disease.Methods:Eleven cases of neonates with moderate or severe hemophilia admitted to our NICU from January 2012 to June 2019 were enrolled.The clinical features, laboratory data, treatments and prognosis of these 11 neonates were retrospectively analyzed.Results:All the neonates were male, and were diagnosed hemophilia A. Seven neonates presented with intracranial hemorrhage including one case complicated with cerebral hernia.Only two of these neonates with intracranial hemorrhage had neurological abnormalities.One case presented with right adrenal hematoma, and one case presented with retroperitoneal hematoma.Jaundice was observed in nine cases, and seven cases, jaundice appeared within two days after birth, whose earliest was 12 hours after birth, and the highest total bilirubin was 388 μmol/L.All cases had prolonged activated partial thromboplastin time.All neonates had decreased activity of coagulation factor Ⅷ including eight moderate and three severe neonatal hemophilia A. Four cases had genetic testing.Three cases infused with fresh frozen plasma and cryoprecipitate and the rest treated with coagulation factorⅧ infusion.Ten cases improved after treatment, and one case abandoned treatment.Conclusion:Moderate or severe hemophilia is often complicated with intracranial hemorrhage or abdominal hemorrhage, often accompanied with hyperbilirubinemia.Imaging examination should be performed to exclude occult bleeding, and coagulation function and coagulation factor activity should be detected as soon as possible.Blood coagulation factors are infused according to the different expected factors of different bleeding sites.
ABSTRACT
Objective:To evaluate the effects of modified peroral endoscopic myotomy (POEM) on esophageal dynamics and clinical efficacy in achalasia (AC) patients.Methods:From January 2013 to December 2014, 51 patients diagnosed with AC and received modified POEM at The First Affiliated Hospital of Sun Yat-sen University were retrospectively enrolled. AC patients were classified as type Ⅰ, type Ⅱ and type Ⅲ according to Chicago classification. The changes of esophageal dynamics before and after the modified POEM were compared by high resolution manometry (HRM). The reflux after the operation was evaluated by 24-hour esophageal impedance-pH monitoring. The clinical symptoms and the quality of life of AC patients were assessed by impaction dysphagia questionnaire (IDQ), Eckardt scale and short-form 36 item health survey (SF-36). Paired t test, independent sample t test, Wilcoxon rank sum test and Pearson correlation analysis were used for statistical analysis. Results:At three months and one year after operation, lower esophageal sphincter pressure (LESP) and integrated relaxation pressure (IRP) were all lower than those before operation ((23.89±12.68) and (23.44±12.56) mmHg (1 mmHg=0.133 kPa) vs. (39.29±16.14) mmHg; (16.13±9.43) and (15.37±8.36) mmHg vs. (30.57±11.31) mmHg), and the differences were statistically significant ( t=7.520, 7.866, 7.641 and 8.909, all P<0.05). There were no statistically significant differences in LESP and IRP during the same period between patients with type Ⅰ AC and type Ⅱ AC (all P>0.05). The LESP of patients with partial esophageal peristalsis function recovered one year after operation was lower than that of patients with unrecovered esophageal peristalsis function ((15.38±4.54) mmHg vs. (25.65±13.19) mmHg), and the difference was statistically significant ( t=0.039, P<0.05). The proportions of pathologic acid reflux of AC patients at three months and one year after operation were 7.8%(4/51) and 2.0%(1/51), respectively. The IDQ and Eckardt scores of patients with AC at three months and one year after operation were both lower than those before operation (4 points, 0 points to 10 points and 4 points, 0 points to 11 points vs. 23 points, 18 points to 30 points; 2 points, 1 points to 3 points and 1 points, 0 points to 1 points vs. 5 points, 4 points to 5 points), and the differences were statistically significant ( Z=-6.036, -6.104, -5.971 and -6.209, all P<0.01). According to Eckardt score, the proportions of clinical remission at three months and one year after operation were higher than that before operation (98.0%, 50/51 and 100.0%, 51/51 vs. 19.6%, 10/51), and the differences were statistically significant ( χ2=64.76 and 68.56, both P<0.05). The SF-36 general health and social function scores at three months and one year after operation were both higher than those before operation (0.55 points, 0.45 points to 0.70 points and 0.55 points, 0.45 points to 0.70 points vs. 0.45 points, 0.30 points to 0.55 points; 0.88 points, 0.75 points to 1.00 points and 0.88 points, 0.75 points to 1.12 points vs. 0.75 points, 0.75 points to 1.00 points); and the differences were statistically significant ( Z=-4.439, -4.225, -2.123 and -2.320, all P<0.05); and the health change scores were lower than those before operation (3.00 points, 2.00 points to 3.00 points and 2.00 points, 1.00 points to 3.00 points vs. 4.00 points, 3.00 points to 4.00 points), and the differences were statistically significant ( Z=-4.827 and -4.841, both P<0.05). Before and after modified POEM, the changes of LESP were positively correlated with the changes of IRP ( r=0.624 and 0.592, both P<0.01). Conclusion:Modified POEM can significantly improve the symptoms and LES relaxation function of AC patients, with a low incidence of post-operative reflux.
ABSTRACT
Objective To investigate the effects and mechanism of verbascoside on hypoxia-induced memory impairment.Methods The eight-arm maze was used to train mice′s spatial memory ability.After successful training, mice were randomly divided into five groups:a normoxic control group (distilled water, 0.1ml/10g), hypoxic model group (distilled water, 0.1ml/10g), the verbascoside low dose group (50 mg/kg), medium dose group (150 mg/kg), and high dose group (300mg/kg) were administered orally once a day for a total of 7days.After administration on the fourth day, except for the normoxic control group was placed in the animal room (1 500m), the remaining four groups were placed in a large-scale hypobaric chamber to simulate the hypoxic environment of the plateau (7 500m, 3days).Eight-armed maze test (4 000m) was used and the plasma and brain tissues were dissected out and measured for reactive oxygen species (ROS) in the brain, malondialdehyde (MDA), reduced glutathione (GSH) and total superoxide dismutase (T-SOD) activity in plasma and brain.Results Compared with the normoxic control group, the indexes of the eight-armed maze, ROS and MDA in the brain, MDA in the plasma of the hypoxia model group were significantly increased, and the GSH and T-SOD enzyme activities in the brain and plasma were notably decreased.Compared with the hypoxic model group, the indexes of the eight-armed maze, ROS and MDA in the brain, MDA in the plasma in the various groups of verbascoside were reduced more or less, the GSH and T-SOD enzyme activities in the brain and plasma slightly were increased.Conclusion Verbascoside could ameliorate the hypoxic memory impairment at high altitude, which might be related to the stabilization of the body′s antioxidant enzyme system balance and
ABSTRACT
OBJECTIVE: This study aims to evaluate the effects and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH agonist) combined with aromatase inhibitor (AI) in preserving the fertility of obese women with grade 1 endometrial cancer (EC). METHODS: This study recruited obese EC patients who wished to preserve their fertility. The treatment regimen consisted of intramuscular GnRH agonist 3.75 mg every 4 weeks and oral AI 2.5 mg daily. The maintenance regimen was the same as the initial treatment regimen. Primary outcomes included response rate, time to complete response (CR), and time to recurrence; pregnancy outcomes included the time to pregnancy, pregnancy rate and live birth rate. RESULTS: Six obese patients with EC were included in this study, with the age (mean±standard deviation [SD]) of 30.5±3.3 years and body mass index (mean±SD) of 35.0±1.4 kg/m2. CR rate was 100%, and time to CR was 3–6 months. None of the patients had recurrence after a median follow-up of 4.0 years (range, 1.3–7.0 years). The most common side effects were menopause-like symptoms. Among these patients, no weight gain was observed during treatment. The pregnancy rate and live birth rate was 50.0% and 75.0%, respectively, with a median time to pregnancy of 2.4 years (range, 1.0–5.5 years). CONCLUSION: The combination of GnRH agonist and AI demonstrated promising long-term effect in young obese EC patients who wished to preserve their fertility. No weight gain side effects were observed. Further studies with a larger sample size are needed to fully evaluate this novel treatment regimen.

<p><b>OBJECTIVE</b>To investigate the clinical epidemiology change trend of upper gastrointestinal bleeding (UGIB) over the past 15 years.</p><p><b>METHODS</b>Consecutive patients who was diagnosed as continuous UGIB in the endoscopy center of The First Affiliated Hospital of Sun-Yat University during the period from 1 January 1997 to 31 December 1998 and the period from 1 January 2012 to 31 December 2013 were enrolled in this study. Their gender, age, etiology, ulcer classification, endoscopic treatment and hospitalization mortality were compared between two periods.</p><p><b>RESULTS</b>In periods from 1997 to 1998 and 2012 to 2013, the detection rate of UGIB was 9.99%(928/9 287) and 4.49%(1 092/24 318)(χ=360.089, P=0.000); the percentage of male patients was 73.28%(680/928) and 72.44% (791/1 092) (χ=0.179, P=0.672), and the onset age was (47.3±16.4) years and (51.4±18.2) years (t=9.214, P=0.002) respectively. From 1997 to 1998, the first etiology of UGIB was peptic ulcer bleeding, accounting for 65.2%(605/928)[duodenal ulcer 47.8%(444/928), gastric ulcer 8.3%(77/928), stomal ulcer 2.3%(21/928), compound ulcer 6.8%(63/928)],the second was cancer bleeding(7.0%,65/928), and the third was esophageal and gastric varices bleeding (6.4%,59/928). From 2012 to 2013, peptic ulcer still was the first cause of UGIB, but the ratio obviously decreased to 52.7%(575/1092)(χ=32.467, P=0.000)[duodenal ulcer 31.9%(348/1092), gastric ulcer 9.4%(103/1092), stomal ulcer 2.8%(30/1092), compound ulcer 8.6%(94/1092)]. The decreased ratio of duodenal ulcer bleeding was the main reason (χ=53.724, P=0.000). Esophageal and gastric varices bleeding became the second cause (15.1%,165/1 092, χ=38.976, P=0.000), and cancer was the third cause (9.2%,101/1 092, χ=3.352, P=0.067). The largest increasing amplitude of the onset age was peptic ulcer bleeding [(46.2±16.7) years vs. (51.9±18.9) years, t=-5.548, P=0.000), and the greatest contribution to the amplitude was duodenal ulcer bleeding [(43.4±15.9) years vs. (48.4±19.4) years, t=-3.935, P=0.000], while the onset age of esophageal and gastric varices bleeding [(49.8±14.1) years vs. (48.8±13.9) years, t=0.458, P=0.648] and cancer [(58.4±13.4) years vs. (58.9±16.7) years, t=-0.196, P=0.845] did not change significantly. Compared with the period from 1997 to 1998, the detection rate of high risk peptic ulcer rebleeding (Forrest stage I(a, I(b, II(a and II(b) increased (χ=39.958, P=0.000) in the period from 2012 to 2013. From 1997 to 1998, 54 patients underwent endoscopic treatment, and the achievement ratio of hemostasis was 79.6% (43/54). From 2012 to 2013, 261 patients underwent endoscopic treatment and the achievement ratio of hemostasis was 96.9%(253/261), which was significantly higher (χ=23.287, P=0.000). Compared to the period from 1997 to 1998, more patients with variceal bleeding or non-variceal bleeding received endoscopic treatment in time (39.0% vs. 70.3%, χ=51.930, P=0.000; 3.6% vs. 15.6%, χ=62.292, P=0.000, respectively), and higher ratio of patients staging Forrest stage I(a to II(b also received endoscopic treatment in the period from 2012 to 2013 [27.4%(26/95) vs. 68.5%(111/162), χ=40.739, P=0.000]. More qualified endoscopic hemostatic techniques were used, containing thermocoagulation (0 vs. 15.2%, χ=79.518, P=0.000), hemostatic clip (0 vs. 55.9%, χ=20.879, P=0.000), hemostatic clip combined with thermocoagulation (4.3% vs. 16.4%, χ=5.154, P=0.023), while less single injection was used (87.1% vs. 6.2%, χ=10.420, P=0.001), and single spraying for hemostasis was completely abandoned in the period from 2012 to 2013. The ratio of inpatients undergoing reoperation decreased obviously in the period from 2012 to 2013 [9.3%(86/928) vs. 6.0%(65/1092), χ=7.970, P=0.005], while no significant difference was found in mortality during hospitalization between two periods.</p><p><b>CONCLUSION</b>Compared with the period from 1997 to1998, the mean onset age of UGIB increased, and the ratio of peptic ulcer bleeding decreased due to the reduction of duodenal ulcer bleeding, the detection rate of high risk peptic ulcer rebleeding increased, the cure rate of endoscopic treatment for UGIB increased, more reasonable and immediate hemostatic methods were used, but overall mortality did not change obviously in the period from 2012 to 2013.</p>

Objective:To summarize the CT features of ankle fracture and to analyze the relationship between the CT images and the most commonly used ankle fracture classification.Methods: With 369 cases of adult ankle fractures analyzed retrospectively,the CT images 1 cm above the ankle joint and its characteristics,the Danis-Weber classification of ankle fracture were studied,and so was the relationship between CT images and the fracture classification.Results: There were 8 forms of CT images.With a,b,and c referred to the fibular fracture,posterior malleolar fracture and interosseous tibiofibular ligament (IOL) rupture respectively.369 CT imges had 40 cases of 0 degree injury (fibula,posterior malleolus,IOL all intact);60 cases of Ⅰa degree injury (fibular fracture,posterior malleolus and IOL intact),3 cases of Ⅰb degree injury (fibula intact,posterior malleolus fracture,IOL intact),26 cases of Ⅰc degree injury (fibula and posterior malleolus intact,IOL rupture);163 cases of Ⅱab degree injury (fibula and posterior malleolus fractures,IOL intact),6 cases of Ⅱac degree injury (fibular fracture,posterior malleolus intact,IOL rupture),61 cases of Ⅱbc degree injury (fibula intact,posterior malleollar fracture,IOL rupture);10 cases of Ⅲ degree injury (fibular fracture,posterior malleollar fracture and IOL rupture).According to the Danis-Weber classification,there were 18 cases of type A,238 cases of type B,94 cases of type C,and 19 cases without fibular fracture.The prevalence of IOL rupture were 0,5.9％,and 88.3％ in types A,B,and C respectively.There was a correlation between the CT image and Danis-Weber classification,the incidence of IOL rupture was changed with the severity of Danis-Weber classification,and the difference was statistically significant after the rank correlation test (Spearman R=0.781,P<0.001).IOL rupture not determined by the fracture classification was found with the CT images and the incidence was 5.9％.Conclusion: Cross-sectional CT images 1 cm above the ankle joint can clearly determine the IOL injury pre-operatively with a good correlation with the Danis-Weber fracture classification,IOL rupture unrecognized with the fracture classification can also be noticed with the CT image.
ABSTRACT
A 8-channel neural signal′s simultaneous transducer detection micro system was developed to research the neural loop located at the brain hippocampus zone. The components of the system contained the neural probe manufactured with the Micro-electro-mechanical-systems (MEMS) technique based on silicon-on-insulator (SOI) substrate, biological low noise chopper-stabilization amplifier, low noise and intermediate speed SAR-ADC converter, reduced and low power ASK/FSK modulation radio transmitter. The micro system was applicable with the characters of small volume, interferences free, neural electrophysiology and neurotransmitter simultaneous detection, high sensitivity, high linearity, etc. The electrode resistance was optimized to 35.0 kΩ after depositing nanometer platinum black on the 4 electrophysiological sites on the Pt electrode. With the modification enzyme technique, nanomaterial enzyme membrane (Pt-mPD-GluOx) was directly fixed on the glutamate detection locus for selectively detecting special neural neurotransmitter matter. In addition, the electrochemistry measurement results indicated that the linear range of glutamate was 6-35 μmol/L with correlation coefficient of 0.97, the sensitivity was 0.0069 pA/(μmol/L). The current response error was less than 3.0 pA, which showed that the neural needle satisfied differential selection. Also, the logic/analog mixed signal 180-nm Application specific integrated circuit (ASIC ) technique (SmicRF180 nm 1Poly6M) was used to manufacture the transducer back-end disposing IC chip, and the test results provided some key parameters such as chopper-stabilization amplifier (equivalent in putting noise voltage ≤0.7 μV rms@1 kHz, gain of 71-82 dB, CMRR/PSRR>100 dB), SAR-ADC (ENOB is 12 bits, power consumption is 1.2 mW when maxmium conversion speed is 1 Msps, signal-noise-ratio is 60.9 dB, etc), and ASK/FSK modulation radio transmitter (the PA′s outputting power of 4-5 dBm, the radiation range of 10 meters). The micro neural transducer integrated system was convenient and wireless wearable for the research of brain hippocampus region.

ABSTRACT
BACKGROUND/AIMS: Anti-reflux barrier dysfunction is one of the primary mechanisms in gastroesophageal reflux disease (GERD) pathogenesis. The esophagogastric junction contractile integral (EGJ-CI) is a new metric adopted to evaluate the EGJ contractility, which implies the anti-reflux barrier function. The aim of the current study was to validate this new metric in patients with GERD and its correlation with the esophageal acid exposure, as well as the efficacy of proton pump inhibitor treatment. METHODS: Ninety-eight patients with GERD and 21 healthy controls were included in the study. Upper endoscopy, high-resolution manometry (HRM) and 24-hour multichannel intraluminal impedance-pH monitoring were performed in all patients. Three respiration cycles were chosen at the initial HRM resting frame and the value computed with distal contractile integral tool was then divided by the duration of the cycles to yield EGJ-CI. All the patients were treated with esomeprazole 20 mg twice-daily for 8 weeks. RESULTS: EGJ-CI was lower in the patients with GERD than that of the controls (P < 0.05). For patients with GERD, EGJ-CI was lower in those with hiatal hernia (P < 0.05). The new metric correlated with esophageal acid exposure in the supine position (P < 0.05), and it also negatively correlated to the total reflux episodes (P < 0.05). There was no significant difference on EGJ-CI between patients with and without response to the esomeprazole treatment (P = 0.627). CONCLUSIONS: EGJ-CI reflected the dysfunction of the anti-reflux barrier in patients with GERD, but it had little impact on the esomeprazole response.

ABSTRACT
OBJECTIVE: To evaluate whether adjuvant simple hysterectomy after concurrent chemoradiotherapy (CCRT) improves progression-free survival (PFS) compared with current standard care in locally advanced cervical adenocarcinoma (LACAC). METHODS: We reviewed a cohort of 55 patients with LACAC (International Federation of Gynecology and Obstetrics [FIGO] stage IB2, IIA2, IIB, III without distant metastasis) diagnosed and treated with radical CCRT at Peking Union Medical College Hospital between January 2004 and October 2014. We compared 34 patients who underwent adjuvant extrafascial hysterectomy with 21 patients with standard care after CCRT. The primary outcome was PFS. Overall survivals (OS) between the two groups were also compared. Surgery feasibility, operative complications, and pathologic features after radiation therapy were also analyzed. RESULTS: PFS was significantly improved in surgery group (log-rank p=0.0097; hazard ratio [HR], 0.3431; 95% CI, 0.152 to 0.772), as were OS (log-rank p=0.0419; HR, 0.3667; 95% CI, 0.139 to 0.964). Analysis of stage IIB demonstrates a similar result. There were no severe complications related to postradiation surgery in this series. The mean blood loss was less in laparoscopic group than those in the open group (87 mL vs. 208 mL, p=0.036, Mann-Whitney U-test). Approximately 47% patients (16/34) had pathologic residue tumor on hysterectomy specimens. About 94% patients (32/34) got complete remission after adjuvant surgery. CONCLUSION: Adjuvant hysterectomy after CCRT improves survival outcome for patients with LACAC compared with current standard care. Extrafascial hysterectomy is sufficient in tumor reduction and laparoscopic procedure may be more promising with lower blood loss and expedite recovery.
