OBJECTIVE: To investigate the short-term clinical effect of lumbar nerve root canal injection under X-ray angiography in the treatment of sciatica. METHODS: The clincal data of 78 patients with sciatica underwent lumbar nerve root canal injection under X-ray angiography from December 2017 to February 2020 was retrospectively analyzed. Including 31 males and 47 females, aged from 22 to 88 years old with a median of 65 years. There were 55 cases of lumbar disc herniation and 23 cases of lumbar spinal stenosis, the course of disease ranged from 1 to 8 weeks with a median of 3 weeks. There were 71 cases of single segment disc herniation or stenosis, including L_3,4 of 5 cases, L_4,5 of 61 cases, L₅S₁ of 5 cases, and 7 cases of multisegment herniation or stenosis. The pain visual analogue scale (VAS) was recorded and Macnab was used to evaluate the clinical effect. RESULTS: All patients completed standardized treatment without serious adverse reactions. VAS were (3.21±0.76) scores immediately after treatment, (2.89±0.33) scores 1 hour after treatment, (1.80±0.27) scores 6 hours after treatment, (1.10±0.20) scores 24 hours after treatment, (2.53±0.35) scores 1 week after treatment and (4.27±0.36) scores 1 month after treatment. There were significant differences in VAS between before treatment(7.83±0.56) and each time period after treatment(P<0.05). According to Macnab low back pain evaluation standard, 42 cases were effective, 34 cases were markedly effective and 2 cases were ineffective within 24 hours after treatment, with an effective rate of 97.4%;38 cases were effective, 25 cases were markedly effective, 15 cases were ineffective within one week after treatment, the effective rate was 80.0%;32 cases were effective, 22 cases were markedly effective, 24 cases were ineffective within one month after treatment, the effective rate was 69.2%. CONCLUSION The short-term clinical effect of nerve root canal injection under X-ray radiography in the treatment of sciatica is good and it is an effective method to relieve sciatica.

Background: With the development of assisted reproductive technology (ART) and its increasing success rate in the mainland of China, more attention has been paid to the safety of ART. In this study, we explored the associations between conception by ART and pregnancy/perinatal complications, and neonatal outcomes compared with similar outcomes following spontaneous conception. Methods: This retrospective cohort study of pregnancies over a 3-year period (2013-2015) was performed at Beijing Obstetrics and Gynecology Hospital, Beijing, China. Subjects were divided into two groups: conception by ART (n = 2256) or spontaneous conception (n = 6768). According to different fertilization modes, the ART group was divided into in vitro fertilization (IVF, n = 1873) and intracytoplasmic sperm injection (ICSI, n = 383) subgroups. The ART group was also divided into two different embryo transfer methods; fresh embryo transfer (ET, n = 1583) and frozen embryo transfer (FET, n = 673) subgroups. Pregnancy complications, perinatal complications, and neonatal outcomes of the enrolled subjects were investigated and analyzed by univariate analysis and multivariate logistic regression. Results: After adjustment for maternal age, gravidity, parity, maternal education, smoking, alcohol consumption, and body mass index (BMI), pregnancies conceived by ART were associated with a significantly increased incidence of gestational diabetes mellitus (GDM; OR 1.88, 95% CI 1.56-2.27), gestational hypertension (OR 2.18, 95% CI 1.83-2.60), and intrahepatic cholestasis of pregnancy (ICP) (OR 2.79, 95% CI 2.15-3.64), compared with spontaneous conception. These associations were similar for the singleton group. In the twin group, only the incidence of ICP was significantly higher than in controls. We found that pregnancies conceived by ART were associated with perinatal complications, including placental abruption (OR 2.14, 95% CI 1.33-3.45), premature rupture of membranes (PROM; OR 1.24, 95% CI 1.06-1.45), postpartum hemorrhage (OR 2.89, 95% CI 2.33-3.59) and polyhydramnios (OR 2.01, 95% CI 1.29-3.16). The singleton group had a similar result with placental abruption, but not with fetal membranes ruptures before labor and polyhydramnios. There were no significant differences in the incidence of these perinatal complications in the twin group. Some neonatal outcomes, including preterm labor (OR 4.29, 95% CI 3.84-4.80) and low birth weight (OR 1.72, 95% CI 1.42-2.08), were more likely to occur with singleton births after ART. However, there were no significant differences for these outcomes from twin pregnancies. Perinatal complications and neonatal outcomes were consistent between the IVF and ICSI subgroups. The FET and ET subgroups showed a similar increase in complications, except for the incidence of placental abruption. After taking into account the effects of parity, birth plurality and maternal age, the ART group still exhibited increased maternal and neonatal complications, although some differences narrowed or disappeared. Conclusions This retrospective cohort study demonstrated that patients who underwent ART were at increased risk of several adverse pregnancy outcomes compared with women who conceived spontaneously. These complications may be attributed in part to the relatively high multiple pregnancy rate after ART. Elective single embryo transfer should be promoted in China to reduce the obstetrical risks of ART pregnancy. Singletons of ART pregnancy exhibited increased maternal and neonatal complications as well, suggesting that underlying infertility or other maternal or parental factors may contribute to the adverse outcomes.

BACKGROUND: T?nnis classification is commonly used to quantify the severity of developmental dysplasia of the hip (DDH), which relies on the presence of the epiphyseal ossification centre. Thereafter, a new classification system (IHDI method) has been developed by the International Hip Dysplasia Institute (IHDI). However, the pathologic morphology has not been defined based on the IHDI grade.OBJECTIVE: To analyze the correlation of the pathologic changes of the hip on MRI with IHDI classification.METHODS: Image data of 65 infants (89 hips) with DDH were analyzed retrospectively, with an average age of 20.4 months. The radiographic severity was graded by IHDI system, and the correlation between IHDI classification and pathological changes of the hip was analyzed, by observing the morphology and position of the limbus, and the cartilaginous acetabular index.RESULTS AND CONCLUSION: (1) A positive correlation was detected between severity of the IHDI grades and age at reduction (r=0.456, P < 0.001). (2) Unexpectedly, the cartilaginous femoral epiphysis still remained contacting with the acetabulum in a part of type III DDH. The cartilaginous acetabular index was significantly increased with IHDI grade increasing (P=0.028). (3) The limbus was everted in all of the type I hips; however, inverted or mixed shape accounted about 60% in the type II hips, 86% in the type III, and 97% in the type IV, respectively. (4) These results manifest that the DDH was severer, and the limbus trended to be more inverted with the increasing in IHDI grade. Moreover,understanding the correlation of the pathologic morphology with the IHDI classification is of great significance for planning an appropriate treatment scheme for DDH.

The present study is to investigate the quality changes of ginseng stems and leaves before and after frost. The contents changes of ginsenoside, free amino acid, and total phenolic compounds, as well as DPPH radical scavenging effect before and after frost were measured. The content of 9 ginsenoside monomer in ginseng stems was decreased except for Rg, and Re after frost, but in ginseng leaves was all decreased. The total content of amino acids was decreased in ginseng stems after frost, while increased in ginseng leaves. The content of phenolic compounds in ginseng stems and leaves were both decreased after frost while the ability of DPPH radical scavenging was improved. The factor of frost has great impact on the quality of ginseng stems and leaves.

OBJECTIVETo evaluate the efficacy and safety of colonoscopy-guided placement of self-expandable metallic stent without fluoroscopic monitoring in the emergence management for acute malignant colorectal obstruction.

METHODSClinical data of 42 patients (24 males and 18 females with a mean age of 64.3 years) undergoing colonoscopy-guided placement of self-expandable metallic stents without fluoroscopic monitoring for acute malignant colorectal obstruction between January 2010 and June 2012 were reviewed retrospectively.

RESULTSThe obstruction was located in the rectum (n=19), sigmoid (n=9), descending colon (n=8), splenic flexure (n=1), hepatic flexure (n=3), and ascending colon (n=2). Technical success was achieved in all the 42 patients (100%). The mean time of operation was (11.8±10.4) min (range 1.1-51.0 min). No serious procedure-related complication occurred. Minor bleeding occurred in 3 cases (7.1%). One patient died on the second day after surgery because of heart failure.

CONCLUSIONSColonoscopy-guided placement of self-expandable metallic stents without fluoroscopic monitoring in emergence management for acute malignant colorectal obstruction is effective and safe with shorter operative time.

Breast capillary hemangioma is a type of benign vascular tumor which is rarely seen. Little is known about its presentation on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Here, we describe a case of suspicious breast lesion detected by DCE-MRI and pathologically confirmed as capillary hemangioma. Our case indicates that a small mass with a superficial location, clear boundary, and homogeneous enhancement on DCE-MRI indicates the possible diagnosis of hemangioma, whereby even the lesion presents a washout type curve.

OBJECTIVETo demonstrate the association of tumor budding with clinicopathological features and prognosis in T2 rectal cancer.

METHODSClinicopathological data of 123 patients who underwent potentially curative resection for T2 rectal carcinoma between 2001 and 2005 at the Changhai Hospital were collected. All pathology slides were stained with hematoxylin and eosin for microscopic examinations. The maximum value of tumor buds(MV) and average value of tumor buds(AV) were calculated, which were classified as low value (≤5), median value (5 < bud value < 10), and high value (≥10).

RESULTSUnivariate analysis and multivariate analysis revealed that MV(P=0.000), AV(P=0.001), and lymphatic invasion (P=0.006) were independent predictors for lymph node metastasis in T2 rectal cancer. Neural invasion and poorly differentiation were significantly associated with MV(P<0.05). Neural invasion, vascular invasion and poorly differentiation were were significantly associated to AV (P<0.01). Disease-free survival (DFS) of patients with low AV, median AV and high AV was 110.5 months, 95.8 months, and 60.0 months respectively. There were significance differences in DFS of low AV with median and high AV(P<0.05). DFS of patients with low MV, median MV and high MV was 115.1 months, 98.5 months, and 86.0 months respectively. There were significance differences in DFS between low and high AV, and median and high MV(P<0.01 and P<0.05), while no significant difference existed between low and median MV.

CONCLUSIONTumor budding is a useful marker to indicate high invasiveness of rectal cancer and a valuable prognostic predictor.

OBJECTIVETo investigate the emergency therapeutic strategy for sigmoid vovulus in the elderly.

METHODSClinical data of 14 elderly patients with sigmoid vovulus were analyzed retrospectively.

RESULTSThe mean age was(79.1±7.2) years(range, 70-93), and 11 patients (78.6%) were male. Emergency decompression and restoration with colonoscopy was performed in all the patients with a success rate of 100%. No patient required emergent surgery. Four patients(28.6%) recurred and they were managed well by repeat colonoscopic restoration.

CONCLUSIONEmergency colonoscopic restoration is the first treatment of choice for sigmoid vovulus in the elderly because it is safe and effective, and can be performed repeatedly.

OBJECTIVETo explore the effect of microRNA (miRNA)-mediated p65 gene knockdown on the proliferation and apoptosis of human breast cancer MDA-MB-231 cells.

METHODSp65-targeted miRNA plasmid was constructed and transfected into MDA-MB-231 cells via lipofectamine(TM)2000. The expression of p65 gene in the transfected cells at the mRNA and protein levels were detected by RT-PCR and Western blotting, respectively. The cell proliferation and apoptosis were measured by MTT assay and flow cytometry (FCM), respectively. The expressions of apoptosis-related proteins were detected by Western blotting in the transfected cells.

RESULTSCompared with the negative control group, the expressions of p65 mRNA and protein in p65miRNA-trasnfected cells were significantly down-regulated (P<0.05). MTT assay showed significantly lowered viability of MDA-MB-231 cells after the transfection (P<0.05). FCM showed an increased cell apoptosis rate in p65miRNA group compared with that in the negative control group (P<0.05). Caspase-3 and PARP were both cleaved into their active forms and the expression of these active forms was increased in p65miRNA group.

CONCLUSIONThe miRNA targeting p65 gene can inhibit the proliferation and induce apoptosis of breast cancer cells, and p65 gene might become a new target in gene therapy for human breast cancer.
