Objective To investigate the clinical manifestation, diagnosis, therapies and medical economics of cesarean scar pregnancy (CSP). Methods From Jan. 2005 to Dec. 2008, 96 patients with CSP treated in Obstetrics and Gynecology Hospital of Fudan University were studied retrospectively. Those cases were divided into 3 groups. Thirty-three patients were treated with methotrexate (MTX) 50 mg/m2 intravenously guttae in group A. Among that 18 cases were treated with MTX, after 5 - 10 days they underwent dilation and curettage of uterus; 15 cases were given by dilation and curettage first if the level of serum human chorionic gonadotrophin-β(β-hCG) descent less than 30% in every 48 hours for 3 times after curettage, then MTX (50 mg/m2) intravenously guttae. Sixty patients were treated with MTX 100 mg bilateral uterine artery injection and embolization in group B. After 2 days, they underwent curettage.Group C: 3 patients were treated with laparotomy lesion excision. The following clinical parameters were compared, including blood loss( M), lesion diameter (-x±s), blood β-hCG level (M)before treatment, the number of cases with myometrial thickness anterior to the CSP ≤3 mm, the resistant index (RI) ≤0. 5,expense(-x ± s), hospital days(-x ±s) in those 3 groups. The correlation of blood loss with lesion diameter and blood β-hCG level was studied. Results ( 1 ) Clinical manifestation: bleeding loss were 20 ml in MTX +curettage of group A, 10 ml in curettage + MTX of group A, 12 ml in group B and 200 ml in group C. The volume of bleeding loss in group C was significantly higher than those in group A or group B ( P ＜ 0. 01 ).The lesion diameter were ( 23 ± 15 ) mm in curettage + MTX of group A and ( 30 ± 14 ) mm of group B ,which were higher than ( 16 ± 8 ) mm of MTX + curettage of group A (P ＜ 0. 01 ). The lesion diameter of (52 ± 7 )mm in group C were significantly bigger than those in the other groups ( P ＜ 0. 01 ). The level of blood β-hCG levels were 21 592 U/L in MTX + curettage of group A, 979 U/L in curettage + MTX of group A,which reach statistical difference ( P ＜0. 05). The level of blood β-hCG levels were 11 312 U/L in group B and 101 U/L in group C. Among 28 cases with Rl≤0. 5,there was 8 cases in group A (24% ,8/33),18 cases in group B ( 30%, 18/60) and 2 cases in group C (2/3). Among 23 cases with myometrial thickness anterior to the CSP ≤ 3 mm, there was 21 cases in group B (35%, 21/60 ), which were significantly higher than 2 in group A (6%, 2/33 ) and none in group C ( P ＜ 0. 05 ). The expense were ( 5578 ± 3679) yuan in MTX + curettage of group A and (5346 ± 2765 ) yuan in curettage + MTX of group,which did not reach statistical difference (P＞0. 05). The expense were (7860 ±2104) yuan in group B,which were significantly higher than those in group A and (5004 ± 421 ) yuan in group C (P ＜ 0. 05 ). The hospital days were ( 15 ±8) days and ( 19 ± 14) days of group A, ( 16 ± 10) days in group B and ( 17 ±8)days in group C, there was no significant difference among those treatments ( P ＞ 0. 05 ). (2) Correlatin:there was positive correlation between bleeding loss and lesion diameter( r = 0. 31, P ＜ 0. 05 ) or blood β-hCG level ( r = 0. 35, P ＜ 0. 05). Conclusions MTX intravenously guttae, MTX uterine artery injection and embolization, and laparotomy lesion excision were all properly used in treatment of CSP. MTX uterine artery injection and embolization was recommended for those with big lesion, high β-hCG level, less myometrial thickness anterior to the CSP or plentiful blood supply of the lesion but the expense might be high.

Objective To evaluate the gene mutation of RANTES and CCR5 in SLE and its significance. Methods One hundred and forty-six definitive SLE patients and 159 controls were collected. SNPs of RANTES promoter and polymorphism of CCR5 were performed by PCR or PCR/RFLP assay, and further confirmed by direct DNA sequencing. Results The frequence of RANTES-403G/G compounded with 28C/C and CCR5/CCR5 was significantly different between SLE and control groups (72.6% vs 58.5%, P 0.05). Conclusions These results indicate that the two SNPs are linkage disequilibrium. Interaction of two SNPs in RANTES and CCR5 is related with SLE. RANTES-403G/G compounded with 28C/C and CCR5/CCR5 may be one of risk factors of SLE. RANTES-403A is probably related with renal damage of SLE.

Objective To investigate clinical significance and application of modified pelvic floor reconstruction developed by Peking Union Medical College Hospital ( MPFR ) in treatment of severe pelvic organ prolapse (POP) by comparing the effectiveness, quality of postoperative sexual life, life satisfaction and risk factors for POP recurrence with the following two surgical procedures: traditional total vaginal hysterectomy with anterior-posterior colporrhaphy (TVH-APC) and total vaginal hysterectomy with lateral colporrhaphy and sacrospinous ligament fixation and vaginal bridge repair and episiotomy (TVH-LC-SSLFVBR-EP). Methods Totally 173 patients with severe POP and at least two compartments defects of pelvic floor underwent surgeries in the study, 86 patients (group A) were treated by MPFR with polypropylene mesh application, 58 (group B) were treated by TVH-APC, and 29 patients (group C) were treated by TVH-LC-SSLF-VBR-EP. Peri-operative data and outcomes of postoperative courses at 6, 12, 18 months were collected and analyzed, in the meantime, the risk factors of recurrence were studied. Results (1) No statistical difference was observed among the above 3 groups in terms of length of operation, amount of blood loss, length of hospital stay, and morbidity after surgery ( P ＞ 0.05). ( 2 ) Cost hospitalization was ( 11 448 ±3049) Yuan in group A, which was significantly higher than (7262 ± 1607) Yuan in group B and (7140 ± 1817 ) Yuan in group C (P ＜ 0.05 ). (3) The length of vaginal cuff of (7.5 ± 1.4) cm in group A and ( 5.6 ± 1.1 ) cm in group C were significantly longer than (7.1±0.6) cm in group B ( P＜0.05). The width of vaginal cuff of (4.3±0.3) cm in group A was larger than (3.4±0.3) cm in group B and (3.3±0.4) cm in group C (P＜0.05). (4) The recurrence rate at 12 months after surgery was 12.8% (11/86)in group A, which was similar with 17.2%(5/29) in group C (P＞0.05) and significantly less than 36.2% (21/58) in group B (P＜0.05). The rate of active sexual life of 16.3% (14/86) in group A was significantly higher than 1.7% (1/58) in group B and 0 in group C ( P ＜ 0. 05 ). The index of life quality improvement at 12 months after surgery was 48±12 in group A, which was no less than 53±16 in group C ( P＞0.05) and higher than 27 ± 9 in group B ( P＜0.05). (5 ) Mesh rejection was observed in 6 patients in group A within 3 months after surgery, while the posterior vaginal wall was exclusively involved. No difference was found in urinary retention or urinary incontinence among three groups (P ＞0. 05 ). (6) The severe degree of POP, type of surgical procedure ( TVT-APC), anterior compartment defect of pelvic floor,and early days of performing pelvic floor reconstruction surgeries were high risk factors for POP recurrence (P＜ 0.05). Conclusions MPFR has a better curative effect and lower recurrence rate on patients with POP. It can help patients regain integrity of anatomical structure and functions of pelvic floor. TVH-LCSSLF-VBR-EP is also effective.

Objective To investigate the expression of sialic acid-binding immunoglobulin-like lectin-one (Siglec-1, also called CD169) in lymphocytes, monocytes and neutrophils in peripheral blood in patients with coronary heart disease(CHD), and explore the relationship between Siglec-1 expression and atheresclerosis. Methods CD145 CD169 positive cell proportion and CD169 mRNA levels were respectively measured by flow cytometry and real-time quantitative reverse transcription-polymerase chain reaction (FQ-RT-PCR) in 57 CHD patients and 38 healthy controls. And the levels of serum hpids were determined by automatic biochemistry analyzer. Results The flow cytometry analysis showed that CD169 protein was not found in lymphocytes and neutrophils in both CHD patients and healthy controls. The rate of CD14 CD169 double positive ceils in monocytes in CHD group was significandy higher than that in healthy controls [(12.7±2.4)% vs (1.0±0.3)% ,t =23.2,P<0.01]. And FQ-RT-PCR analysis showed that the mean CD± mRNA copy number in PBMCs in CHD group was significantly higher(3.2 fold) than that in healthy controls [t = 6. 59, P < 0.01]. However, neither differences of CD169 protein positivities [[(12. 2 ± 2. 3) %vs (13.4±2.5)% ,t = 1.87,P >0.05] nor mRNA levels [3.64 fold vs 2.79 fold when compared with healthy controls,t =0. 98, P > 0. 05] were found between CHD patients with normal and abnormal levels of serum Lipids. Conclusions CD169 is mainly expressed in human tissue-resident macrophages but not expressed in peripheral blood monecytes. And when the monocytes is stimulated by inflammation, the expression of CD169 is increased. In patients with CHD, the increased expression of CD169 protein and mRNA level has demonstrated the activation of monocytes in peripheral blood. CD169 and CD169-mediated monocytes activation may play an important role in the development and progression of atherosclerosis.

Objective:To investigate the effect of continuous intracranial pressure (ICP) and brain oxygen partial pressure (PbtO 2) monitoring and guiding treatment after the application of standard large bone flap decompression and microhematoma removal in patients with severe traumatic brain injury (TBI). Methods:A retrospective analysis was done of 41 patients with TBI in Department of Neurosurgery in the Inner Mongolia People's Hospital from January 2018 to May 2020. Patients with Glasgow coma scale (GCS)<8 points were treatesd with microscopical removal of hematoma and contusion brain tissue and standard large bone flap decompression. Intraoperative intracranial pressure and brain tissue oxygen partial pressure monitoring probes were placed. Postoperatively, continuous intracranial pressure monitoring and partial oxygen pressure monitoring of brain tissue were performed, and target-based treatment under ICP and PbtO 2 monitoring was performed. According to the Glasgow Outcome (GOS) score after six months, patients were divided into a good outcome group (4-5 scores) and a poor outcome group (1-3 scores). There were 26 cases in good prognosis group and 15 cases in poor prognosis group. Linear regression analysis was used to further evaluate the relationship between PbtO 2, ICP and GOS score. The measurement data of normal distribution were compared by independent sample t-test. The counting data were expressed in cases (%), and the comparison between groups was adopted χ 2 inspection. The general linear bivariate Pearson correlation test was used. Results:The mean value of PbtO 2 (17.42±5.34) mmHg in the poor prognosis group was lower than that in the good prognosis group (24.65±5.61) mmHg, with statistical significance ( t=4.04, P<0.001). The mean value of ICP (22.32±3.45) mmHg in the poor prognosis group was higher than that (17.32±3.23) mmHg in the good prognosis group, with statistical significance ( t=4.15, P<0.001). Using PbtO 2 and ICP as independent variables and GOS score after 6 months as dependent variable, a regression equation was established ( Y=4.040 X+7.497; Y=-2.549 X+28.63). The mean value of PbtO 2 was positively correlated with GOS scores after 6 months in patients with severe head injury ( r=0.75, P<0.001). The mean value of ICP was negatively correlated with the prognosis of patients with severe head injury ( r=-0.87, P<0.001). Conclusion:The treatment guided by ICP combined with PbtO 2 monitoring is valuable in improving the prognosis of patients with severe traumatic brain injury after standard decompressive craniectomy, and may improve the prognosis 6 months after the injury.

Objective:To observe the expression of glucose regulated protein 78 (GRP78) in glioma and its clinical value in evaluating clinical prognosis.Methods:A total of 163 patients with glioma who were surgically removed and confirmed after surgery in the People′s Hospital of Inner Mongolia Autonomous Region were collected from March 2012 to October 2015. Immunohistochemical staining was used to observe the expression of GRP78 in patients with different WHO grades of glioma. Chi square test was used to compare the expression of GRP78 in glioma patients with different age, gender and WHO grade. Whether COX regression analysis GRP78 can be used as an independent prognostic indicator was investigated. Time series test and Kaplan Meier analysis were used to analyze the survival time of patients with different GRP78 expression levels.Results:The expression of GRP78 was up-regulated in glioma, and the patients with high expression of GRP78 (positive expression/strongly positive expression) were more common in stage Ⅲ/Ⅳ than in stage Ⅰ/Ⅱ. The expression of GRP78 was not statistically significant in different age and gender groups ( P>0.05), but was statistically significant in different WHO stages ( P<0.01). GRP78 was an independent prognostic factor for glioma ( P = 0.045). The median survival time of patients with glioma was 28 months (95% CI 37.594 to 47.046), of which the survival time of patients with high expression of GRP78 was 15 months (95% CI 12.922 to 40.801); the survival time of patients with low expression of GRP78 was 35 months (95% CI 39.807 to 51.352), and the difference was statistically significant ( P<0.01). The survival time of patients with high expression of GRP78 was significantly shorter than that of patients with low expression of GRP78 ( χ2 = 13.588, P<0.01). Conclusions:The expression level of GRP78 in glioma is significantly increased; high expression of GRP78 is more common in Ⅲ/Ⅳ glioma, and GRP78 can be used as an effective index to evaluate the poor prognosis of glioma.

Objective:To investigate the application of continuous intracranial pressure (ICP) combined with regional cerebral oxygen saturation (rScO 2) monitoring in patients with hypertensive intracerebral hemorrhage before and after operation of the removal hematoma through small bone window and the effect on the prognosis of patients. Methods:The clinical data of 37 patients with supratentorial hypertensive intracerebral hemorrhage admitted to the neurosurgical intensive care unit of the people′s Hospital of Inner Mongolia Autonomous Region from April 2018 to October 2020 were retrospectively analyzed.ICP monitoring and near infrared spectroscopy (NIRS) were used to monitor the intracranial pressure and rScO 2 concentration before and after the operation, and the changes of intracranial pressure and rScO 2 before and after the operation were analyzed.According to Glasgow Outcome Score (GOS), patients with GOS score>3 were classified as good prognosis group (21 cases), and those with GOS score ≤3 were classified as poor prognosis group (16 cases). Results:The postoperative intracranial pressure((15.80±6.70) mmHg)of patientswith hypertensive intracerebral hemorrhage was lower than that before operation((20.40±5.80) mmHg), and the difference was statistically significant( t=3.226, P=0.002). The postoperative rScO 2 ((62.31±3.85)% )of patientswith hypertensive intracerebral hemorrhage was higher than that before operation((59.73±3.13)%), and the difference was statistically significant( t=3.171, P=0.002). The decrease of intracranial pressure in patients with good prognosis((6.53±2.21) mmHg)was more obvious than that in patients with poor prognosis((4.24±2.30) mmHg). The concentration of rScO 2 increased in both groups.But in the group with good prognosis, the rScO 2 increased((3.99±2.34)%)was significantly higher than that in poor prognosis group((2.32±2.25)%). Six months after operation, there were significant differences in preoperative and postoperative intracranial pressure and rScO 2 between good prognosis group and poor prognosis group, and the difference was statistically significant( t=3.090, 2.176; P=0.004, 0.036). Conclusion:Small bone window evacuation of intracerebral hematoma can significantly reduce the concentration of intracranial pressure and increase the concentration of rScO 2 in patients with intracerebral hemorrhage.The changes of intracranial pressure and rScO 2 before and after operation have potential value in judging the prognosis of patients.

Objective:To investigate the role of multimodal neuronavigation intraoperative and sodium fluorescein-guided techniques in microsurgery for intracranial malignant neoplasm.Methods:A retrospective analysis was conducted on 50 patients with intracranial malignant tumors treated by microsurgery from 2016 to 2019 in Inner Mongolia People′s Hospital. Preoperative imaging included computed tomography (CT), computed tomographic angiography (CTA), magnetic resonance imaging (MRI), MRI: MRA, MRV, DWI, PWI, DTI, DTI, MRS sequence scan, and before the operation, they were fused with the functional nervous system navigation workstation of Bo Yilai to make the navigation plan. During the operation, the functional navigation was combined with low dose fluorescein sodium (2 mg/kg) for operation. Intraoperative neuronavigation was used to determine the location of the tumor and its spatial relationship with the pyramidal tract of the main fiber conduction tract and the large blood vessels, and intraoperative yellow fluorescence mode of pentero900 Zeiss microscope showed the boundary between the tumor and normal brain tissue for tumor resection.Results:There were 38 cases of glioma, 10 cases of brain metastasis of lung cancer, 1 case of brain metastasis of renal clear cell carcinoma and 1 case of spindle cell tumor. The accuracy of preoperative neuronavigation was 95%. Compared with the preoperative lesions, MRI of the head was reexamined 3 days after operation to judge the degree of tumor resection. In this group, 38 cases (76%) were totally resected and 12 cases (24%) were subtotal resected. The 6-month survival rate was 85.9%, the 12-month survival rate was 53.1%, the 18-month survival rate was 24.5%, and the survival time was (15.0 ± 3.2) months.Conclusion:Multimodal functional neuronavigation combined with fluorescein sodium staining can locate and label tumors in real time, improve tumor resection rate, and improve the prognosis of brain cancer patients.
