BACKGROUND: Prognosis is determined by degrees of outside force and time of spinal cord compression after spinal cord injury. The former factor cannot be changed, but the latter one can be changed through relieving spinal cord compression as early as possible to promote nervous function recovery.OBJECTIVE: To compare the effect of surgical intervention time on nervous function recovery within 72 hours and 10 to 14 days after cervical spinal cord injury.DESIGN: Randomized controlled and before-after controlled study.SETTING: Department of Spine Surgery of the Second Hospital affiliated to Harbin Medical University.PARTICIPANTS: A total of 32 patients with cervical spinal cord injury were selected from the Department of Spine Surgery of the Second Hospital affiliated to Harbin Medical University from April 1998 to August 2001.All patients were divided into two groups according to randomly alternative criteria. There were 16 cases including 10 males and 6 females in early surgical group (within 72 hours) and there were also 16 cases including 12males and 4 females in delayed surgical group (within 10-14 days).METHODS: Patients in early surgical group were undertaken operation at 72 hours after hospitalization, and patients in delayed surgical group were at 10-14 days after hospitalization. Frankel grade, sensory and motor scores were recorded according to criteria set by American Spinal Injury Association before operation and within 24 months after operation.MAIN OUTCOME MEASURES: ① Sensory and motor scores before and after operation; ② Frankel grade before and after operation.RESULTS: ① Improved level of sensory score (difference before and after operation) was higher in early surgical group than that in delayed surgical group (42.6±20.2, 19.2±19.1, P < 0.01). ② Improved level of motor score (difference before and after operation) was higher in early surgical group than that in delayed surgical group (39.7±17.8, 17.3±18.6, P < 0.01). ③Improved level of Frankel grade in early surgical group was superior to that in delayed surgical group (P < 0.01).CONCLUSION: Nervous function recovery of patients with acute cervical spinal cord injury who were suffered from operation within 72 hours is superior to that of those within 10 to 14 days. Therefore, surgical intervention should be undertaken as early as possible in order to promote nervous function recovery after cervical spinal cord injury.

Journal of Zhejiang University. Science. B 2020;21(12):940-947
Background: The proportion of recurrences after discharge among patients with coronavirus disease 2019 (COVID-19) was reported to be between 9.1% and 31.0%. Little is known about this issue, however, so we performed a meta-analysis to summarize the demographical, clinical, and laboratorial characteristics of non-recurrence and recurrence groups. Methods: Comprehensive searches were conducted using eight electronic databases. Data regarding the demographic, clinical, and laboratorial characteristics of both recurrence and non-recurrence groups were extracted, and quantitative and qualitative analyses were conducted. Results: Ten studies involving 2071 COVID-19 cases were included in this analysis. The proportion of recurrence cases involving patients with COVID-19 was 17.65% (between 12.38% and 25.16%) while older patients were more likely to experience recurrence (weighted mean difference (WMD)=1.67, range between 0.08 and 3.26). The time from discharge to recurrence was 13.38 d (between 12.08 and 14.69 d). Patients were categorized as having moderate severity (odds ratio (OR)=2.69, range between 1.30 and 5.58), while those with clinical symptoms including cough (OR=5.52, range between 3.18 and 9.60), sputum production (OR=5.10, range between 2.60 and 9.97), headache (OR=3.57, range between 1.36 and 9.35), and dizziness (OR=3.17, range between 1.12 and 8.96) were more likely to be associated with recurrence. Patients presenting with bilateral pulmonary infiltration and decreased leucocyte, platelet, and CD4+ T counts were at risk of COVID-19 recurrence (OR=1.71, range between 1.07 and 2.75; WMD=−1.06, range between −1.55 and −0.57, WMD=−40.39, range between −80.20 and −0.48, and WMD=−55.26, range between −105.92 and −4.60, respectively). Conclusions: The main factors associated with the recurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after hospital discharge were older age, moderate severity, bilateral pulmonary infiltration, laboratory findings including decreased leucocytes, platelets, and CD4+ T counts, and clinical symptoms including cough, sputum production, headache, and dizziness. These factors can be considered warning indicators for the recurrence of SARS-CoV-2 and might help the development of specific management strategies.

Objective To summarize the sonographic features and differential diagnosis points of mass-type cornual pregnancy. Methods The sonographic ifndings of 23 pathological proven mass-type cornual pregnancy cases enrolled in PUMCH from 2011 January to 2013 January were retrospectively analyzed. Results All pathological proven mass-type cornual pregnancy were located at one corner of the uterus presenting as a heterogenous outward mass. Well-deifned margins were found in 20 cases, and interstitial-line signs were found in 15 cases. The surrounding muscle thickness is 0.1-0.3 cm. Typical hyperechoic villi were found on sonography in cases with bloodβ-hCG>20 000 IU/L. On Doppler, the lesion showed abundant peripheral vascularity with low resistance in 22 cases, 9 lesions also showed abundant internal vascularity. Among 23 mass-type cornual pregnancy cases, 7 cases were misdiagnosed as gestational trophoblastic neoplasia (GTN) due to the similar sonographic characteristics including mixed-echo and abundant vascularity with low resistance. Sixteen cases were diagnosed by ultrasound preoperatively, with featured sonographic signs including mass located in the endometrial extension line;clear margin;peripheral vascularity;or detection of interstitial-line sign and typical villus. Conclusions Mass-type cornual pregnancy may be correctly diagnosed according to the location, boundary of the mass and the distribution of blood flow combining with clinical manifestation and bloodβ-hCG level. Transvaginal sonography could play an important role in diagnosis of cornual pregnancy.

Objective To study the influence of survivin targetedly inhibited with antisense oligonucleotide (ASODN)technique on the apoptosis of hepatoma carcinoma cells SMMC-7221,and to clarify the mechanism of promotion effect of survivin-ASODN on the apoptosis of SMMC-7721 cells.Methods The ASODN sequence of survivin marked by FAM fluorescein was designed and synthized. The SMMC-7721 cells were transfected by different concentrations (100,200,300,400,and 600 nmol· L-1 )of survivin-ASODN (ASODN transfection groups),at the same time blank control group and blank liposome control group and sense oligonucleotide (SODN) control group were set up.The apoptotic rates and the changes of cell cycle of the SMMC-7721 cells 24,48,and 72 h after transfected with different concentrations of survivin-ASODN were detected by FCM. The expression levels of survivin were measured by Western blotting method.Results Compared with each control group,24 h after transfection,the apoptotic rates of survivin-ASODN transfected SMMC-7221 cells were increased,the growth of cells was inhibited (P<0.05),and the effects had time-dose dependent tendency.48 h after transfection,the hypodiploid apoptotic peak appeared in ASODN transfection groups before G1 phase, the number of the cells at G0/G1 phase was decreased (P<0.05)and the number of the cells at G2/M phase wsa increased (P<0.05). Compared with each control group,the survivin expression levels in the SMMC-7721 cells in ASODN transfection groups were decreased (P<0.05 ), and the effects of survivin-ASODN was time-dose dependent (P<0.05 ). Conclusion Survivin-ASODN can block the expression of survivin in SMMC-7721 cells and inhibit the proliferation of SMMC-7721 cells by changing the cell cycle and increasing apoptosis in a time-dose dependent manner.

ObjectiveTo investigate the clinical characteristics and therapy of fresh cervical spinal cord injury without radiographic abnormality (SCIWORA) in children.MethodsThe materials of fourteen SCIWORA children (13 cases treated with non operative menthod, 1 case treated by atlantoocciptal fusion) were analyzed retrospectively.ResultsOne child was dead, and the other 13 cases had a 3-year follow up. Three children's symptoms had no change. According to ASIA criterion, there were 3 cases with grade A, 5 cases with grade B, 5 cases with grade C and 1 case with grade D before treatment. After treatment, there were 1 case recovered to grade B, 2 cases recovered to grade C, 5 cases recovered to grade D, 2 cases recovered to grade E.ConclusionSpinal cord injury caused by a short time dislocation of cervical vertebrae is the main reason of SCIWORA in children. The degree of the injury of spinal cord is related directly with the recovery of function of nervous system. Most patients can get satisfactory results by non operative methods. Operations are useful to the cases with obvious instability of cervical spine.
