Objective To summarize the preliminary experience of coils, Onyx and covered stents for the treatment of carotid-cavernous sinus fistula (CCF). Methods Of the 25patients with CCF, 22 were traumatic CCF, and 3 were spontaneous CCF; the fistula orifices of 14 patients were located in the cavernous segment of right internal carotid artery (ICA), and 11were located in the cavernous segment of left ICA. According to the Barrow classification,Types A, C, and D were 22,2, and 1, respectively. Eighteen patients were treated with Guglielmi detachable coils alone, 1 was treated with Guglielmi detachable coils and Onyx, 2 were treated with Onyx alone, and 4 were treated with covered stents. Results Intracranial bruit disappeared immediately in all patients after the procedures. Postoperative angiography showed complete occlusion of the fistula orifices, the symptoms disappeared after 1 to 20 days, and there were no death and procedure-related complications. The recanalized ICAs were patent in patients (12/18) treated with coils, and the ICAs were patent in 4 patients treated with the covered stents.The ICAs were patent in 2 patients treated with Onyx, the ICA was patent in 1 patent treated with detachable coils and Onyx. One patient with traumatic CCF treated with coils had clinical recurrence, and was cured after re-embolization with coils. The remaining patients were followed-up for 6 to 24 months, and no recurrence of clinical symptoms was found. The followup cerebral angiography of 6 patients was obtained, and no CCF recurrence was observed.Conclusion Endovascular treatment with Guglielmi detachable coils, Onyx, and covered stents is a safe and useful method for closing CCFs.

OBJECTIVE：To c ompare the situation of adverse drug reaction （ADR） collection by social media between European and American countries and China ，so as to provide reference for the improvement of corresponding work in China. METHODS：By retrieving relevant literatures from CNKI ，Web of Science ，Elsevier ScienceDirect ，SpringerLink and so on ， referring to the official website of International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use （ICH），the current situation of ADR collection by social media in European and American countries（organizations）such as the United States ，the European Union ，the United Kingdom ，France was introduced ，and compared with the corresponding work in China. The advantages and possible problems of using social media to collect ADR were analyzed so as to put forward some suggestions on how to use social media to collect ADR in China. RESULTS & CONCLUSIONS：Since 2013，many countries in Europe and the United States have started to collect ADRs using social media （such as Twitter ，Facebook），such as the draft on drug safety issues on social media issued by the Pharmaceutical Research and Manufacturers of America （PhRMA），and the EU organization ’s Innovative Medicines Initiative （IMI）network to identify adverse drug reaction in web media （WEB-RADR）projects. Through this way ，it is more convenient for patients to report ADR ，and helpful for the pharmacovigilance department to collect ADR information in time ，and can be used as an important supplement to the traditional drug safety information report. However ，there are some advantages ，such as mismatch between the health vocabulary spontaneously reported by patients and medical professional vocabulary ，the challenges of balancing the relationship between public health maintenance and patient privacy protection ，and various deviations affecting the reporting rate and quality of ADR collected by social media. When using social media （such as Wechat ，microblog，QQ and other social media or tools ，as well as applications and small programs ）to collect ADR information in China ，it is suggested to ensure the ease of use and security of reporting ADR applications ，and improve the design of applications to comply with E 2B （R3） data elements and information specifications of ICH guidelines for the electronic transmission of individu al security reports. At the same time ，we should give full play to the supervisory role of regulatory department ，consider non-regulatory factors ，and take privacy protection measures to make it conform to ethics.

Objective: To observe the neuro-protective effect of Levocarnitine on severe hand, foot and mouth disease (HFMD) after enterovirus 71(EV71) infection, to preliminarily explore the possible mechanism preliminarily. Methods: One hundred and thirty-two children with EV71 infection and HFMD combined with serum S100 protein and neuronspecific enolase (NSE) abnormalities who were admitted to Children′s Hospital Affiliated to Zhengzhou University from March 2015 to July 2016 were enrolled in the study.They were divided into the routine group and the Levocarnitine group by the random number grouping method.The routine group (66 cases, including 32 males and 34 females, median age of 2 years and 3 months) was given symptomatic treatment such as antiviral therapy while the Levo-carnitine group (66 cases, including 36 males and 30 females, median age of 2 years and 5 months) was treated with Levocarnitine for neuroprotection on the basis of routine group.Forty healthy children (23 males and 17 females, median age of 2 years and 6 months) who were examined at the Children′s Hospital Affiliated to Zhengzhou University during the same period were selected as the healthy control group.The levels of S100, NSE, soluble apoptosis-related factors (sFas), soluble apoptosis-related factor ligands (sFasL), malondialdehyde (MDA), superoxide dismutase (SOD) in serum were compared between the healthy control group and children with HFMD.The levels of above-mentioned indexes in cerebrospinal fluid and serum, efficacy-related indicators such as duration of fever, white blood cell count on the 3^rd day of treatment, time to remission of nervous system symptoms, time of disease progression and critical conversion rate were compared between 2 groups of children with HFMD.The correlation between sFas, sFasL, MDA, SOD and S100, NSE was performed Results: (1) The levels of S100 [(0.38±0.16) μg/L vs. (0.06±0.23) μg/L], NSE [(43.70±8.80) μg/L vs. 10.10±3.60) μg/L], sFas [(6.61±1.86) μg/L vs. (3.88±1.22) μg/L], sFasL[(101.40±20.7) μg/L vs. (54.4±13.3) μg/L] and MDA[(11.98±2.54) nmol/L vs. (4.08±1.45) nmol/L] in serum of HFMD group were significantly higher than those of the healthy control group (t=-12.245, -22.895, -8.273, -12.803, -17.960, all P<0.05), while the SOD level [(57.10±10.40) kU/L vs. (70.3±14.4) kU/L] was significantly lower (t=5.457, P<0.05). (2) With the extension of treatment time for HFMD children in the two groups, S100 and NSE in cerebrospinal fluid, S100, NSE, sFas, sFasL and MDA in serum decreased, while SOD level increased.On the 3^rd and 7^th day after treatment, S100 (t₃=3.491, t₇=14.434), NSE (t₃=2.920, t₇=23.490) in cerebrospinal fluid, S100 (t₃=5.277, t₇=3.614), NSE (t₃=4.652, t₇=10.525), sFas (t₃=6.399, t₇=7.514), sFasL (t₃=11.155, t₇=8.804) and MDA (t₃=6.348, t₇=7.499) in serum of Levocarnitine group were significantly lower than those of routine group (all P<0.05), while SOD (t₃=3.162, t₇=-3.529) was significantly higher than that of routine group (P<0.05). (3) The relief time of neurological symptom in levocarnitine group was significantly shorter than that in the routine group [(1.23±0.65) d vs. (1.84±0.47) d], and WBC on the 3^rd day after treatment [(9.14±2.93)×10⁹/L vs. (7.12±2.58)×10⁹/L] and the progression time of the disease [(29.74±7.85) h vs. (17.36±8.73) h] were significantly better than the those in the routine group (t=-6.178, 4.204, 8.567, all P<0.05). The critical conversion rates of Levocarnitine group and the routine group were 7.58% and 18.18%, respectively, and the difference in critical conversion rate was not statistically significant (χ²=2.316, P>0.05). (4)There was a positive correlation between S100 and sFas, sFasL, MDA in children with HFMD (r=0.373, 0.735, 0.334, P<0.05). NSE was positively correlated with sFas and sFasL (r=0.479, 0.601, all P<0.05), while SOD and S100 were negatively correlated with NSE (r=-0.425, -0.460, all P<0.05). Conclusions Levocarnitine has good curative effect on severe HFMD in children infected by enterovirus EV71, which can effectively protect the cranial nerves.The mechanism may be related to scavenging oxygen free radicals and blocking nerve cell apoptosis.

Objective To clarify the effect of iodine intake on serum thyroglobulin (Tg). Methods A 5-year prospective study was conducted in the 3 different iodine intake areas in China [Panshan (miht deficiency) ,Zhangwu (more than adequate) and Huanghua (excess)]. A total of 3 099 people with normal serum levels of Tg in 1999 were followed and 2 448 of these participants were feasible to be observed in 2004 and included in the present study. The serum levels of Tg, thyraglobulin antibody(TgAb), thyroid peroxidase antibody(TPOAb) and TSH, thyroid volume, family and personal histories of thyroid diseases were measured and inquried. The general linear model (GLM) was used to explore the determinants of Tg. Results Among the study population at baseline, serum Tg were significantly different in three areas [7.5 (4.4-13. 1) μg/L at Panshan, 6.8 (3.6-11.2)μg/L at Huanghua, 5.9 (3.2-10.7) μg/L at Zhangwu, P<0.01]. They were associated with age, sex and the rate of positive TgAb, abnormal thyroid volume, abnormal TSH and positive personal history of thyroid diseases, in order to control the effects of confounding factors, the data from 1856 subjects with thyroid-related indexes all in normal range and without personal history of thyroid diseases were analyzed to clarify the effect of iodine intake on Tg. The serum Tg among three areas were significantly different in both 1999 and 2004, they were all increased in 5 years with significant augment (△ Tg) among the three areas[3.1 (-0.2-8.0) μg/L at Panshan, 3.5 (0.5-9.0)μg/L at Huanghua vs 2. 5(0.3-6.1) μg/L at Zhangwu,P<0.01]. The GLM analysis revealed that age, Tg and TSH levels at baseline were the determinants of △Tg in addition to iodine intake. Conclusion Iodine intake is a dominant determinant of serum Tg. Age and TSH should also be considered while indicating iodine intake by serum Tg.

Objective:To explore the pros and cons of sequential high-flow nasal cannula (HFNC) and non-invasive positive pressure ventilation (NIPPV) immediately following early extubated patients with severe respiratory failure (SRF) due to acute exacerbations of chronic obstructive pulmonary disease (AECOPD), so as to provide evidence for clinical selection of optimal scheme.Methods:Consecutive AECOPD patients admitted to the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University from January 2019 to September 2020 were screened for enrollment. Patients were between 40 years old and 85 years old with acute exacerbation of bronchial-pulmonary infection, who received endotracheal intubation mechanical ventilation (ETI-MV) as the initial respiratory support method. The pattern of synchronous intermittent mandatory ventilation (SIMV) was used in the study. The parameters were set as follows: tidal volume (VT) 8 mL/kg, support pressure 10-15 cmH 2O (1 cmH 2O = 0.098 kPa), positive end-expiratory pressure (PEEP) 4-6 cmH 2O and the ratio of inspiratory to expiratory time 1.5-2.5∶1. Under these conditions, the plateau pressure (Pplat) was maintained less than 30 cmH 2O. The minimum fraction of inspired oxygen was adjusted to keep the pulse oxygen saturation no less than 0.92. When the pulmonary infection control window (PIC window) occurred, the subjects were extubated immediately and randomly divided into two groups, with one group receiving HFNC (called HFNC group), the other group receiving NIPPV (called NIPPV group). Patients with failed sequential HFNC or NIPPV underwent tracheal re-intubation. The rate of tracheal re-intubation within 7 days of extubation, complications (such as nose and face crush injury and gastric distension), in-hospital mortality, duration of ETI before PIC window, length of RICU stay and length of hospital stay were compared, respectively. Results:Forty-four patients were enrolled in the study, 20 in the HFNC group and 24 in the NIPPV group. There was no significant difference in the duration of ETI before PIC window between HFNC and NIPPV groups (hours: 95.9±13.1 vs. 91.8±20.4, P > 0.05). The rate of tracheal re-intubation within 7 days in the HFNC group was significantly higher than that in the NIPPV group [35.0% (7/20) vs. 4.2 % (1/24), P < 0.05]. However, the incidence of complication in the HFNC group was significantly lower than that in the NIPPV group [0% (0/20) vs. 25.0% (6/24), P < 0.05]. Compared with the NIPPV group, the in-hospital mortality in the HFNC group was slightly higher [5.0% (1/20) vs. 4.2% (1/24)], the length of RICU stay (days: 19.5±10.8 vs. 15.5±7.2) and the length of hospital stay (days: 27.4±12.2 vs. 23.3±10.9) were slightly longer, without statistical differences (all P > 0.05). Conclusion:For early extubated patients with SRF due to AECOPD, the compliance of sequential HFNC increased and the complications decreased significantly, but the final effect may be worse than sequential NIPPV.

Nonalcoholic fatty liver disease (NAFLD) has become one of the most prominent causes of chronic liver diseases and malignancies. However, few therapy has been approved. Radix Bupleuri (RB) is the most frequently used herbal medicine for the treatment of liver diseases. In the current study, we aim to systemically evaluate the therapeutic effects of saikosaponin A (SSa) and saikosaponin D (SSd), the major bioactive monomers in RB, against NAFLD and to investigate the underlying mechanisms. Our results demonstrated that both SSa and SSd improved diet-induced NAFLD. Integrative lipidomic and transcriptomic analysis revealed that SSa and SSd modulated glycerolipid metabolism by regulating related genes, like
