RESUMEN
ObjectiveTo investigate the effect and mechanism of Shuxuetong and its main component hirudin on the apoptosis of cerebellar granule neurons （CGNs） in Sprague-Dawley（SD） rats. MethodsCGNs incubated in vitro for 7 days were divided into survival control group or 25 K group （cultured in medium containing 25 mmol/L KCL） and apoptosis group or 5 K group （cultured in medium containing 5 mmol/L KCL）. CGNs were separately treated with proportionally diluted and different concentrations of Shuxuetong （1/50， 1/40， 1/30， 1/20 and 1/10） and the corresponding different concentrations of hirudin （2， 2.5， 3.34， 5 and 10 U / mL）. Hoechst staining was performed to analyze the apoptosis. Western blot was used to detect the expression levels of Cleaved Caspase-3， Bim and VEGF. ResultsHoechst staining showed that 5 K group had a higher apoptosis rate than 25 K group. In 25 K group， there was no significant change in the apoptosis rate between neurons treated with different concentrations of Shuxuetong and hirudin， but significant changes was found in 5 K group and the higher the concentration， the lower the apoptosis rate. Western blot results revealed that， compared with control neurons in 5 K group， Shuxuetong injection and hirudin treatments resulted in a decrease of Cleaved Caspase-3 and Bim expression， but an increase of VEGF protein. ConclusionsShuxuetong and its main component hirudin inhibits the apoptosis of CGNs through suppressing proapoptotic BH3-only protein Bim.
RESUMEN
Background: Microvascular decompression (MVD) has become widely accepted for hemifacial spasm (HFS). The significance of facial nerve notch (FNN) for the outcome after MVD is still unknown. Objective: To investigate the correlative analysis between the FNN at the root exit zone (REZ) and the curative effect of MVD for HFS. Method: A prospective study was performed, which included 232 patients with Cohen score ≥2 who had undergone MVD. The patients were divided into two groups: the group with facial nerve notch (FNN) and the group without FNN, according to whether there is FNN caused by the offending vessels during the MVD operation. All the patients were followed up for 24 months. Results: The group with FNN caused by offending vessels at the REZ area was confirmed in 119 patients, of which 117 patients were immediately cured and two patients received partial relief on the 1st day of postoperation. The group without FNN at the REZ area was confirmed in 113 patients, of which 43 patients were immediately completely cured while 70 patients were not immediately completely cured after MVD operation. After 24 months of follow-up, 119 patients with FNN were all completely cured, 71 patients without FNN were completely cured, and 42 patients without FNN were not completely cured. Multivariate logistic regression analysis shows that compared with without FNN group, the FNN group had statistical significance for the clinical results both on the-1st -day (P < 0.01) and 2 years of follow-up (P < 0.05) after MVD operation. Conclusions: FNN is an important reference factor to evaluate both the short-term and long-term curative effect of microvascular decompression for hemifacial spasm. The postoperative effect of patients with FNN is much better than that of patients without FNN.

Objective:To investigate the value of high-frequency ultrasound and shear wave elastography in preoperative evaluation of basal cell carcinoma (BCC) .Methods:A total of 95 patients with histopathologically confirmed cutaneous BCC were enrolled from Department of Dermatology, Hospital of Traditional Chinese Medicine of Zhongshan from January 2017 to December 2020, all of whom had underwent preoperative conventional ultrasonography and shear wave elastography. Conventional ultrasonography parametres including the maximum diameter, maximum infiltration depth, maximum blood flow velocity and resistance index were recorded, so were shear wave elastography parametres including the average Young′s modulus (Eave) , Young′s modulus standard deviation (Esd) and average Young′s modulus ratio (Eratio) . All the patients were divided into high- and low-risk BCC groups according to pathologic subtypes. Paired t-test was used to compare conventional ultrasonography and shear wave elastography findings between the 2 groups. Results:There were 15 cases in the high-risk BCC group and 80 cases in the low-risk BCC group. Compared with the low-risk BCC group, the high-risk BCC group showed significantly increased maximum depth of tumor infiltration (8.5 ± 4.6 mm vs. 4.5 ± 1.6 mm, t = 6.150, P < 0.001) , Eave (32.7 ± 11.2 kPa vs. 20.6 ± 5.1 kPa, t = 4.065, P = 0.001) and Esd (7.0 ± 4.1 kPa vs. 4.2 ± 2.1 kPa, t = 2.632, P = 0.018) , while there were no significant differences in the other measurement data between the two groups (all P > 0.05) . The areas under the receiver operating characteristic curves of the maximum infiltration depth, Eave and Esd for the diagnosis of high-risk BCC were 0.775, 0.909 and 0.822 respectively, and Eave showed the best diagnostic performance. Using 25.7 kPa as the cut-off value, the sensitivity and specificity of Eave were 86.7% and 85.0% for the diagnosis of high-risk BCC, respectively. Conclusion:High-frequency ultrasound and shear wave elastography can facilitate differential diagnosis between high- and low-risk BCC.

Objective To explore how the different intervention measures affect the outcome of central venous catheter-related thrombosis (CRT) in children. Methods A retrospective analysis was carried out to collect the clinical data of patients with CRT from the nursing management system of the Children′s Hospital Affiliated to Zhejiang University School of Medicine which reported by each nursing unit from January 1,2015 to December 31,2015. Results Totally 108 cases were included (72 boys and 36 girls), median age of 24.5 months (ranged from 1 month to 14 years old). Nearly 42.59% (46/108) patients suffered from neurological diseases. Nearly 55.56%(60/108) CRT was detected in the first week after catheterization. Once CRT conformed, there were four kinds clinical intervention options applied. Intervention 1: thrombolytic therapy with urokinase combined anticoagulation with nadroparin calcium. Intervention 2: anticoagulant therapy only. Intervention 3: thrombolytic therapy alone. Intervention 4: no medications. The differences of effective between the four kinds of intervention were statistically significant (χ2=13.380, P=0.004). The single-factor regression analysis was done to each relevant factor. Finally the multivariate regression analysis showed four factors had impacts upon the results. The factors were as follows:gender (OR=10.400, 95%CI 1.879-57.563, P=0.007);interval (OR=1.107, 95%CI 1.035-1.184, P = 0.003), size of thrombus(OR = 1.562,95%CI 1.033-2.362,P=0.035; Intervention 2 (OR =11.757, 95% CI 2.254- 61.327, P = 0.003), intervention 4 (OR = 35.397, 95% CI 3.493-358.760, P =0.003). Conclusions The earlier and small size thrombus is more soluble. Thrombolytic therapy or combined anticoagulation is more effective. It is recommended that if no contraindications presents, thrombolytic combined with anticoagulant therapy should start early standardized treatment.

Objective To investigate the effect of elemene and the mechanism of this effect on the proliferation of neuroblastoma.Methods We treated cultured SK-N-SH cells with elemene and used the MTT assay to determine the inhibition of cell proliferation.We used RT-qPCR and Western blotting to measure the effect of elemene on mRNA and protein expression,respectively,of repressor element-1 silencing transcription factor (REST) in SK-N-SH cells and evaluated the mRNA expression of CCND1 and CCNE1 in SK-N-SH cells by using RT-qPCR.Results Elemene significantly inhibited the proliferation of SK-N-SH cells in a dose-and time-dependent manner (P =0.001 16).Moreover,the mRNA (P =0.000 38) and protein (P =0.003 39) expression of REST were markedly suppressed by elemene.Furthermore,elemene significantly reduced the mRNA expression of CCND1 (P =0.001 91) and CCNE1 (P =0.000 15),which are related to the cell cycle.Conclusion Elemene significantly suppressed the proliferation of neuroblastoma cells through the reduction of REST,CCND1,and CCNE1.
RESUMEN
Objective To explore the prognostic factors of intensive care unit (ICU) patients. Methods A retrospective cohort study was conducted. The clinical data of patients admitted to ICU of Beijing Geriatric Hospital from January 2005 to December 2016 were collected. According to the prognosis, the patients were divided into death group and survival group, and the mortality trend with time and age was observed. Survival and death were treated as dependent variables, while the gender, age, reason of ICU admission, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, whether undergoing invasive mechanical ventilation (MV), invasive MV reason, duration of invasive MV, whether successful weaning, whether ICU nosocomial infection, hospital acquired pneumonia (HAP), central line-associated bloodstream infection (CLABSI), acute kidney injury (AKI) occurred, whether undergoing continuous blood purification (CBP), whether septic shock occurred, whether undergoing invasive hemodynamic monitoring or blood transfusion and length of ICU stay were used as the independent variables. First, the clinical data was analyzed by univariate analysis. Second, the independent variables influencing the dependent variable were analyzed by logistic regression analysis to screen out prognostic factors of ICU patients. Results During the study period, 1325 patients were treated, 26 patients with missing data, 1299 patients in final group, 865 patients in survival group, and 434 in death group. The proportion of men in the patients was larger (67.7%), and the age span was larger (16-105 years old). The mortality rate in different years showed no significant difference (χ2 = 16.712, P = 0.117), and with the increase of age, the mortality rate of ICU showed an upward trend (χ2 = 16.399, P = 0.022). The univariate analysis showed that ICU deaths were unrelated to gender, but associated with age, APACHE Ⅱ score, invasive MV, invasive MV reason, duration of invasive MV, successful weaning, ICU nosocomial infection, HAP, CLABSI, AKI, septic shock, whether CBP or invasive hemodynamic monitoring, blood transfusion, the reason of ICU admission and the length of ICU stay (all P < 0.05). The relevant factors with statistical difference found in univariate analysis were analyzed in logistic regression analysis, which showed that whether successful weaning [odds ratio (OR) = 0.016, 95% confidence interval (95%CI) = 0.010-0.025], and whether AKI (OR = 3.917, 95%CI = 2.331-6.582) or septic shock occurred (OR = 2.808, 95%CI = 1.604-4.915) were the dependent variables of death or survival (all P = 0.000). Regression coefficient (β value) of successful weaning was -4.155, suggesting that unsuccessful weaning patients were likely to die. The β value of AKI and septic shock was 1.365 and 1.033, suggesting that the patients with AKI or septic shock were more likely to die. Conclusions Whether the success of weaning, whether the occurrence of AKI or septic shock are independent prognostic factors for the prognosis of ICU patients. Measures for the prevention of the above three aspects could improve the prognosis of ICU patients.
RESUMEN
Objective To study the closure time of neonatal ductus venosus and the Z score regression equation, and to explore the variation of closure time of neonatal ductus venosus with gestationalage.Methods Color doppler ultrasound was applied to detect the closure time of neonatal ductus venosus in normal newborns, Z score regression equation ( lnY =a +bX +cX2 ) for the closure time of neonatal ductus venosus ( Y ) was developed by regression analysis which used gestational age ( X) as an independent variable. The Z scores of the closure time of neonatal ductus venosus in different gestational age were calculated by the formula [ Z = ( M - Y )/S x , M for observation value, Y for predictivevalue].Results There were 432 cases in our study.The closure time of neonatal ductus venosus was negatively related to gestational age ( r = -0. 938 , P <0. 001 ) . The nonlinear regression equation was lnY= -5. 228+0. 089X-0. 000228X2, R2 =0. 854, Sx =0. 214(P<0. 001). Based on the predicted mean of the closure time and Sx related to different gestational age, Z scores for specific closure time of neonatal ductus venosus could be calculated by the formula [ Z =( M -Y)/Sx ] . The Z scores were normally distributed,and did not change with gestational age.Conclusions Theclosure & nbsp;time of neonatal ductus venosus is negatively related to gestational age. The Z scores obtained by the predicted nonlinear regression equation are normally distributed.

RESUMEN
Objective To assess the safety and efficacy of stent-assisted coil embolization for acutely ruptured wide-necked intracranial aneurysms. Methods We retrospectively reviewed 192 wide-necked intracranial aneurysms in 178 patients. The efficacy and peri-procedure complications of stent-assisted embolization were compared between rup?ture aneurysms and unrupture aneurysms. Results Stent was successfully implanted in 78 rupture aneurysms and 114 un?rupture aneurysms. There was statistically significant difference between rupture aneurysms and unrupture aneurysms groups in rate of poor prognosis on discharge ( 23.1%vs. 5%,χ2=12.726, P0.05)nor in the rate of mortality and permanent disability (8.9%vs. 6.1%,χ2=0.475, P>0.05). Angiograms at 14.7 months of follow-up did not reveal any significant difference between rupture aneu?rysms and unrupture aneurysms groups in aneurysm complete occlusion (74.1%vs. 70.6%,χ2=0.197,P>0.05), recana?lization (10.3%vs. 9.4%,χ2=0.034,P>0.05)and in-stent stenosis (3.4%vs. 4.7%,χ2=0.136,P>0.05). Conclusion Stent-assisted coil embolization for acutely rupture wide-necked intracranial aneurysms can prevent recurrence effective?ly and can achieve high complete occlusion rate in long term follow-up. However, its procedure related complications and mortality is higher in rupture aneurysms than in unrupture aneurysms, which indicates that a caution is needed to conduct stent-assisted coil embolization in rupture aneurysms.

RESUMEN
To observe the protective effects of Salvia miltiorrhizae injection on multiple organs of rats with SAP or OJ. Two hundred eighty-eight rats were used for SAP-associated experiments and OJ-associated experiments. The rats were randomly divided into sham-operated, model control and treated group. According to the different time points after operation, the SAP rats in each group were subdivided into 3, 6 and 12 h groups while the OJ rats were divided into 7, 14, 21 and 28 days groups. The mortality rates, pathological changes and ICAM-1 (only in lung), TLR4 (only in liver), Bax and NF-kappaB proteins expression in multiple organs (liver, kidney, lung, intestinal mucosa, spleen, thymus and lymph nodes) were observed, respectively. The mortality rates of treated groups decreased in both SAP and OJ experiments. Compared to model control group, the pathological changes can be seen in treated groups including; (1) the pathological changes of multiple organs in SAP and OJ experiments were improved, the pathological severity scores of kidney (at 6 h), intestinal mucosa (at 12 h), spleen (at 6 and 12 h), thymus (at 3 and 6 h) and lymph nodes (at 3 and 6 h) in SAP experiment and of liver (on 21 and 28 days), lung (21 days), intestinal mucosa (on 21 and 28 days) and spleen (on 21 and 28 days) in OJ experiment significantly declined (P < 0.05 or P < 0.01); (2) the positive rate of Bax protein in pancreas (at 3 h) and liver (on 6 and 12 h) in SAP experiment and in liver (on 28 days), kidney (on 21 days), and thymus (on 28 days) in OJ experiment were significantly lower (P < 0.05 or P < 0.01); (3) the positive rate of NF-kappaB in liver (at 12 h) and kidney (at 6 h) in SAP experiment and in liver (on 21 days), kidney (on 28 days), intestinal mucosa (on 28 days) and thymus (on 14 days) in OJ experiment significantly decreased (P < 0.05). (4) the positive rate of ICAM-1 in lungs (at 12 h) in SAP experiment was significantly less (P < 0.05). Salvia miltiorrhizae injection can protect multiple organs of SAP or OJ rats and inhibit the expression of ICAM-1, TLR4, NF-kappaB and regulate Bax proteins. Salvia miltiorrhizae may relieve the inflammation response and enhance the immunity function of SAP and OJ rats.
