RESUMO
BACKGROUND:The type of graft selected during anterior cruciate ligament revision is considered one of the main factors affecting the postoperative outcome,but there are few reports on the comparison between different graft materials. OBJECTIVE:To explore the medium-to-long-term clinical efficacy after anterior cruciate ligament revision with autologous ligament,allogeneic ligament,and LARS artificial ligament. METHODS:A total of 67 patients with the first anterior cruciate ligament revision admitted to the Department of Joint and Sports Medicine,The Second Hospital of Tangshan from May 2011 to May 2020 were selected,including 41 males and 26 females,with a mean age of(45.83±7.39)years.They were divided into three groups according to different grafts used:autologous ligament group(n=24),allogeneic ligament group(n=22),and LARS artificial ligament group(n=21).Follow-up for more than 36 months after revision was performed to evaluate the effect of revision. RESULTS AND CONCLUSION:(1)International Knee Documentation Committee(IKDC)score,Lysholm knee score,and Tegner motor score 1 year after surgery and at the last follow-up in the three groups were higher than those before surgery(P<0.05).There were no significant differences in IKDC score,Lysholm knee score,and Tegner motor score among the three groups 1 year after surgery and the last follow-up(P>0.05).(2)The lateral differences of KT-1000 at 1 year after surgery and the last follow-up among the three groups were lower than those before surgery(P<0.05).The lateral difference of KT-1000 and the positive rate of the axial shift test in the last follow-up of the LARS artificial ligament group were higher than those in the autologous ligament group and allogeneic ligament group(P<0.05).(3)At the last follow-up,X-ray films showed no obvious enlargement of the reconstructed bone tunnel and no obvious failure of the graft fixation device.There was no obvious aggravation of osteoarthritis,but bone density decreased significantly in some elderly patients.(4)These findings suggest that anterior cruciate ligament revision with LARS artificial ligaments can obtain good initial stability,but with the extension of time,the stability of partial cases tends to decrease,even with reconstructed ligament failure.Both allogeneic and autogenous ligaments can obtain good clinical efficacy in anterior cruciate ligament revision.
RESUMO
This paper reports the maternal and fetal outcomes of three twin pregnancies with chronic hypertension and obstructive sleep apnea-hypopnea syndrome (OSAHS) who were treated with continuous positive airway pressure (CPAP). All three women with twin pregnancies were diagnosed with chronic hypertension. Furthermore, symptoms such as snoring and apnea assisted the diagnosis of OSAHS through polysomnography monitoring. Case 1 was treated with CPAP at 28 gestational weeks. The blood pressure increased gradually after the first month of CPAP treatment, with an elevated urine protein concentration. At 34 gestational weeks, the pregnant woman underwent a cesarean section due to the development of hemolysis, elevated liver enzymes, and low platelet syndrome. Case 2 was treated with CPAP at 11 gestational weeks, with stable blood pressure throughout the pregnancy, and was delivered through cesarean section at 37 weeks of pregnancy. Case 3 started CPAP at 13 gestational weeks for four months, and increased blood pressure and urine protein were observed. Medication brought the blood pressure down, and urine protein became negative. At 32 gestational weeks, a cesarean section was performed because of premature rupture of the membrane. Her CPAP treatment continued till delivery with good maternal and infant outcomes. The treatment outcomes of the three cases suggest that CPAP may prolong the time of blood pressure rise among twin pregnancies where chronic hypertension and OSAHS coexist, which potentially reduces the occurrence of adverse maternal and infant outcomes.
RESUMO
Objective:To study the protective effect of Mongolian medicine Bateri-7 on radiation-induced intestinal injury in mice.Methods:C57BL/6J male mice were randomly divided into control group, irradiation group and irradiation plus drug administration group, with 10 or 15 mice in each group. For irradiation group, the mice were given a single dose of 12 Gy 60Co γ-rays with total body irradiation. For drug treatment, the mice were gavaged with Bateri-7 (530 mg/kg) 7 d before irradiation until 3 d after IR. At 6 h and 24 h after irradiation, the Tunel positive cells in intestine were detected immunohistochemically. At 3.5 d after irradiation, the structure of intestinal villi was observed by HE staining, and the BrdU and Ki67 positive cells were detected immunohistochemically. The expression levels of IL-6, TNF-α and Cxcl-5 were detected by qPCR. The FITC-dextran in peripheral blood was also determined. Results:The survival of irradiated mice was significantly increased by Bateri-7 ( χ2= 5.84, P < 0.05), but there was no significant difference in weight between two groups ( P > 0.05). The villi length of small intestine in the irradiation plus drug group was significantly longer than that in the irradiation group ( t = 20.24, P < 0.05), and there was no significant difference in the depth of intestinal crypt between two groups ( P > 0.05). At 6 and 24 h after irradiation, the number of Tunel positive cells in intestinal crypts in the irradiation plus drug group was significantly reduced in comparison with the irradiation group ( t = 3.52, 2.90, P < 0.05). At 3.5 d after irradiation, the level of FITC-dextran in serum and the expressions of IL-6, TNF-α and Cxcl-5 in small intestine of mice in the irradiation plus drug group were significantly lower than those in the irradiation group, respectively( t = 6.92, 7.01, 7.18, 13.16, P < 0.05). The number of BrdU and Ki67 positive cells in the crypt of mice in the irradiation plus drug group was higher than that of the irradiation group ( t = 3.91, 2.57, P < 0.05). Conclusions:Mongolian medicine Bateri-7 can effectively alleviate irradiation-induced intestinal injury of mice, which may have a good preventive and therapeutic effect on radiation enteritis.
RESUMO
Objective:To investigate the efficacy and pregnancy outcome of fertility-preserving treatment for patients with stage Ⅰa, grade 2 endometrial cancer (EC).Methods:Clinical data was retrospectively collected for EC or atypical endometrial hyperplasia (AEH) patients treated in Peking University People's Hospital, Foshan First People's Hospital of Guangdong Province and First Affiliated Hospital of Sun Yat-sen University, from 2010 to 2019. Inclusion criteria for fertility-preserving treatment included: (1) Age ≤45 years. (2) EC with histological differentiation of G 1, G 2 or endometrial AEH. (3) EC disease should be stage Ⅰa, confined to the endometrium without myometrial invasion, lymph node or extrauterine metastasis. Treatment regimen: patients were given oral progestin therapy and endometrial pathology was evaluated every three months. Patients were divided into three groups as G 2 EC group, G 1 EC group and AEH group based on the histological differentiation. Oncological and pregnancy outcomes were compared among them. Results:(1) Totally 57 eligible patients were included in this study, including 11 cases with G 2 EC, 22 cases with G 1 EC, and 24 cases with AEH. (2) Oncological outcome: among the three groups of G 2 EC, G 1 EC and AH, the complete remission rates (9/11, 91% and 96%, respectively) and recurrence rates (3/9, 30% and 22%, respectively) were not significantly different (all P>0.05). Median remission time was significantly longer in the G 2 EC group than those in the other two groups (8, 6 and 4 months; P=0.046). Among 9 G 2 EC patients who recurred after complete remission, three patients relapsed at 7, 18 and 53 months, respectively. All 3 patients chose fertility-sparing treatment again, and all achieved complete remission after retreatment. (3) Pregnancy outcome: among the three groups, the assisted reproduction technology rates (4/8, 5/18 and 36%, respectively) and pregnancy rates (6/8, 5/18 and 36%, respectively) had no significant difference ( P>0.05). However, time interval to pregnancy was shorter in G 2 EC patientsthan the other two groups (4, 9 and 22 months, respectively; P=0.006). Conclusions:Fertility-preserving treatment for patients with stageⅠa, G 2 endometrial cancer, may obtain a relatively high remission rate and an acceptable pregnancy rate. However, further exploration is needed due to the limited number of cases.

RESUMO
BACKGROUND:To improve local microenvironment and reduce local scars is conducive to peripheral nerve regeneration that promotes nerve function recovery.OBJECTIVE:To evaluate the effect of fresh amniotic membrane on the regeneration of tinjured peripheral nerve.METHODS:Sixty healthy Sprague-Dawley rats were randomly divided into three groups (n=20 per group) after constructing a model of sciatic nerve injury of the unilateral leg. In group A, the nerve was wrapped with fresh human amnion at the anastomosis end after the repair of nerve. In group B, the nerve was wrapped with biofilm at the anastomosis end after the repair of nerve. In group C, no treatment was conducted after the repair of nerve (blank control). The effects were evaluated by anatomical observation, light microscope observation, immunohistochemical detection (2, 4, 8, 12 weeks after surgery), transmission electron microscope observation, axon imaging analysis, action potential detection, and sciatic nerve function index (4, 8, 12 weeks after surgery).RESULTS AND CONCLUSION: (1) Gross observation. The amniotic membrane and biofilm were absorbed partialy at postoperative 2 weeks, mostly at postoperative 4 weeks and completely at postoperative 8 weeks. In the groups A and B, the nerve was adhered slightly and loosely to the surrounding tissues, with a fair range of motion. In the group C, the nerve was tightly adhered to the surrounding tissues, with a poor range of motion. (2) Observation under light microscope. The nerve regeneration was better in the groups A and B than group C at 2, 4, 8, 12 weeks postoperatively. (3) Observation under electron microscope. Regenerated nerve fibers were rarely seen and lamelar structures were unclear in the three groups at 4 weeks postoperatively. Then, increased regenerated nerve fibers, thickened myelin sheath, clear lamelar structure and enlarged axon diameter were found in the groups A and B compared with the group C at 8 and 12 weeks postoperatively. (4) Immunohistochemical detection. The expression and distribution of S-100 protein in the groups A and B were better than those in the group C. (5) Axon image analysis. Groups A and B were superior to the group C in the diameter of myelinated nerve fibers, thickness of myelin sheath and number of regenerated nerve fibers. There was a significant difference by statistical analysis (P < 0.05). (6) Electrophysiological examination. Shorter latency period, higher amplitude and faster nerve conduction velocities were observed in the groups A and B compared with the group C (P < 0.05). (7) The sciatic function index. The sciatic function index in group A or B was significantly higher than that in group C (P < 0.05). To conclude, the human amniotic membrane can reduce adhesion between the damaged nerve and surrounding tissues, and prevent scarring at the anastomosis end. In addition, it promotes the regeneration of nerve fibers, increase axon diameter and myelin sheath thickness, and ease inflammatory and immune responses at the neural incision.
RESUMO
Objective To discuss the influence of bath frequency on neonatal skin condition and body temperature. Methods 108 newborns from obstetrics of People′s Hospital of Peking University during November 2015 to December 2015 were selected, and were randomly distributed t into two groups by lottery. The control group took bath every day, whereas the experimental group did every three days. The newborns were followed up for 4 weeks on their skin condition and body temperature. Then the data were systemized and performed statistical analysis. Results During the first 4 weeks after babies were born, the control group and experimental group showed no significant difference on their skin condition (P>0.05). When compared at the time of first 3 days, 1 week and 2 weeks after the babies were born, body temperature of the experimental group were (36.693±0.182), (36.738±0.174), (36.772±0.185)℃, while the control group were (36.591 ± 0.160), (36.671 ± 0.158), (36.684 ± 0.155)℃,which tended to be significantly lower than the experimental group (t values were -2.697,-2.087,-2.669, P 0.05). Conclusions Reducing the bath frequency form once a day to every third day showed no influence on neonatal skin condition. Meanwhile, it did avoid significant reduce of body temperature after bath. This may help improve healthy skin care of newborns, promote their growth, and at the same time, redistribute the clinical nursing work efficiently.
RESUMO
SUMMARY Pheochromocytomaisrareinpregn’ancy.Clinicalfeaturesofacaseofpheochromocytoma during pregnancy in the Peking University People’s Hospital was investigated and the literature reviewed to discuss the diagnosis and treatment of this disease.The patient manifested with hypertension and pro-teinuria,who was easily misdiagnosed with gestational hypertension disease.When she was transferred to our hospital,the symptoms such as,paroxysmal palpitation,dizziness,vomiting were noticed,and the possibility of pheochromocytoma was considered due to the accompanying abdominal mass.An emergent cesarean section was performed successfully due to preterm labor during the treatment of the disease.Af-ter the delivery the drug preparation continued.And the laparoscopic resection of pheochromocytoma pro-ceeded when the blood pressure was steady.The patient recovered fully after the surgery.The final diag-nosis of pheochromocytoma was confirmed with the pathology.Its diagnosis and treatment experiences could improve our understanding and treatment of secondary hypertension due to pheochromocytoma in pregnancy.
RESUMO
BACKGROUND:Experiments have demonstrated that biological membranes can be usedtorecon struct thetendon she athandin hibit exogenou shealing of thetendon.Therefore,the semembrane sprovide a good bed for tendon gliding and reduce tendon adhesion. OBJECTIVE:To compare the effectsof acelular amniotic membrane and medical membraneagainst tendon adhesion during the repair oftendon sheath defects. METHODS:ToesIIIfrom the bipeds of 66 leghorns were chosen to prepare tendon injury and tendon sheath defect models, which were randomly divided into three groups (n=22 per group). Amnion group were repaired with acelular amniotic membrane, medical membrane group with absorbable membrane, and control group had no treatment on tendon sheath defects. Gross, histological and biomechanical tests of each group were performed at 2, 4, 8, 12 weeks after surgery. RESULTS AND CONCLUSION:At 12 weeks after surgery, in the amniotic membrane and medical membrane groups, the tendon sheath formed completely, and the tendon healed well, with no adhesion, but in the control group, there was serious tendon adhesion. At 8 weeks after surgery, the number of synovial cells in the false sheath was highest in the amniotic membrane group sequentially followed by the medical membrane group and control group. In the amniotic membrane group, the rough endoplasmic reticulum expanded highly and secreted exuberantly in the matrix, while in the control group, the synovial cells presented with messy arrangement, and expanded vacuoles in the matrix were weaker than those in the other two groups. At 12 weeks after surgery, fibroblasts were arrayedtidily in layerwith dense structure in the medical membrane and amniotic membrane groups;but in the control group, fibroblasts were distributed disorderly with loose structure. Tendon sliding distance and total flexor toe angle in the amniotic membrane and medical filmgroups were significantly larger than those in the control group (P < 0.05),butthere was no significant difference between the medical membrane and amniotic membrane groups. Additionally, the maximum tensile fracture strength had no significant difference among three groups at 12 weeks after surgery. These results indicate that both amniotic membrane and medical membrane can markedlyprotect the tendon from exogenous healing and adhesion.
RESUMO
Objective:To evaluate the seven existing vaginal birth after cesarean (VBAC)screening tools and to identify additional factors that may predict VBAC or failed trial of labor in China.Methods:In the study,53 patients with 1 previous cesarean delivery who then delivered between January 1,2007 and Novenber 31,2014 were recruited.The average age of the patients was (32.1 ±3.5 )years,the average gestational age was (38.0 ±2.3)weeks.There was no significant difference of the successful group and the failed group in the maternal /neonatal mortality and morbidity,also in the incidence of the postpartum hemorrhage and the postpartum infection.The probability of VBAC was calculated for each participant using 7 prediction models created by Weinstein,Flamm,Grobman,Gonen,Troyer,Smith and Torri.The data were analyzed using t test,rank-sum test,and receiver operating curve analysis. Results:44 trial of labor patients had a vaginal birth after cesarean delivery,and the successful rate was 83%.The scores between the successful group and the failed group had significant difference when eva-luated by Weinstein and Grobman scoring models only.After recalculating the successful rate of VBAC in different score levels according to the references,there was significant difference between the rates of dif-ferent score levels when evaluated by the Weinstein model.The successful rates of different score levels were higher compared to the references (<50%)when evaluated by the Troyer (70%),Gonen (60%),Torri (85.7%)models.The area under the receiver operating characteristic curve of Weinstein prediction model (0.746)and Flamm prediction model (0.723)were more than 0.7,and there was no significant difference between the seven models.Conclusion:Among the seven scoring models,the Weinstein model is more applicable to the population of our country,but a new model more applying to Chinese women still needs to be created.

Objective To compare the differences and similarities between the diagnostic criteria of obstetrics and internal medicine in China with that of Hibbard for peripartum cardiomyopathy (PPCM).Methods From March 1995 to September 2009, a total of 49 patients were diagnosed as PPCM at the Peking University People's Hospital and the Fu Wai Hospital in Beijing, China. Obstetric diagnostic criteria was:PPCM was one of dilated cardiomyopathy,occurred during the third trimester of pregnancy through the 6th month postpartum,and without cardiovascular diseases before. Internal medicine diagnostic criteria was:PPCM was unexplained cardiomegaly and heart failure, occurred during the last month of pregnancy through the 5th month postpartum, and meet the echocardiographic criteria of dialated cardiomyopathy as follows:left ventricular end-diastolic dimension (LVEDd) greater than 5.0 cm; left ventricular ejection fraction (LVEF)less than 45% , and(or) left ventricular fractional shortening (LVFS) less than 30% ; or LVEDd greater than 2. 7 cm/body surface area (m2) ; or LVEDd > 117% of age and body surface area predictive value. Hibbard diagnostic criteria was: All four of the following: (1) heart failure within last month of pregnancy and 5 months postpartum; (2) absence of prior heart disease; (3) no determinable cause; (4) strict echocardiographic indication of left ventricular dysfunction; LVEF less than 45% , and/or LVFS less than 30% , and LVEDd greater than 2. 7 cm/m2. The compliance between obstetric and internal criteria with Hibbard criteria, and the reasons of incompliance between Chinese and international criteria were analyzed. Results Eight patients were diagnosed of PPCM by obstetricians according to Chinese obstetric criteria. Among them, 6 patients (6/8) did not meet Hibbard criteria. 2 of the six did not reach the time regulated in the criteria. All of the six had other determinable causes for heart failure, and their echocardiographic results did not meet the diagnostic standard either. The other 41 patients were diagnosed of PPCM by physicians according to Chinese internal medicine criteria. Among them, 7 patients (17%) did not meet Hibbard criteria, 3 of the seven did not reach the time regulated in the criteria, and had other determinable causes for heart failure either. 4 of the seven did not meet the echocardiographic standard part in the criteria. The Chinese internal medicine diagnostic criteria has a significant higher coincidence rate with Hibbard criteria, compared to Chinese obstetric criteria (83% vs. 25% ; P <0. 01). Among all 13 patients whose PPCM diagnosis did not meet Hibbard criteria, 5 cases did not reach the time regulated in the criteria, 9 cases had other determinable causes for heart failure, and 10 cases did not meet the echocardiographic standard part in the criteria. Preeclampsia was the most common determinable causes for heart failure, accounted for 7 cases. Conclusion There is obvious difference between Chinese and Hibbard diagnostic criteria for PPCM, especially Chinese obstetric criteria.
