ABSTRACT
Objective To investigate the effect of different doses of statins on the clinical efficacy and safety outcome of intravenous thrombolytic therapy of urokinase in patients with acute ischemic stroke(AIS).Methods Based on a large prospective,multicenter study,the Chinese Intravenous Thrombolysis Registry for AIS within 4.5 h of onset(INTRECIS)database,clinical data of 898 patients with urokinase intravenous thrombolysis for AIS were retrospectively analyzed.According to the amount of statin used during hospitalization,the patients were divided into 132 patients in no-statin group,591 patients in conventional statin group and 175 patients in intensive statin group.Clinical outcome measures included 14-day improvement in the National Institutes of Health Stroke Scale(NIHSS)and 90-day excellent prognosis(improved Rankin score≤1 point).Safety measures included recurrent stroke,bleeding events,and 90-day all-cause mortality.Results After adjusting for differences in baseline characteristics(age,coronary heart disease,diabetes,atrial fibrillation,systolic blood pressure,OTT,DNT,previous anti-plate use,blood glucose,and treatment in Class A hospitals),NIHSS scores improved at 14 days after admission and excellent prognosis at 90 days after admission in convention-dose and intensive statin groups were superior to those in no-statin group(P<0.05);Univariate and multivariate analysis of safety outcome indicators showed no statistically significant differences in stroke recurrence and bleeding events among the three groups(P>0.05);The 90-day all-cause mortality was significantly higher in no-statin group(10.6%)than in convention-dose statin group(2.0%)and intensive dose statin group(2.9%)(P<0.01).Conclusions In patients with AIS who were treated with intravenous urokinase thrombolytic therapy,intensive statin use was associated with improved 14-day NIHSS score and near-term prognosis without increasing the risk of stroke recurrence and bleeding events.Statin use is beneficial to reduce mortality.
ABSTRACT
ObjectiveTo investigate the diagnosis and treatment of familial hypokalemic periodic paralysis with acidosis. MethodsThe proband's medical history, clinical manifestations, laboratory examinations and imaging characteristics were retrospectively analyzed, and prevalence situation of family members was investigated in detail. Next generation sequencing technology was used to detect the pathogenic gene loci related to periodic paralysis, and the relevant literatures were summarized. ResultsThe proband was definitely diagnosed as familial hypokalemic periodic paralysis. There was a heterozygous mutation in the SCN4A gene of the proband, which was c.2006G>A, resulting in amino acid changes R669H.The proband's grandfather, father and uncle shared the same variation. ConclusionsFamilial hypokalemic periodic paralysis with paroxysmal acidosis is rare, which is easily misdiagnosed as renal tubular acidosis. c 2006G>A mutation in SCN4A gene is the molecular basis of the disease in this family. The clinical phenotypes of different gene mutations are different, and gene screening is helpful for diagnosis and treatment.
ABSTRACT
Objective@#To investigate the effects of estrogen deficiency on depression-like behavior and mitochondrial function in hippocampus,and to study the underlying mechanisms.@*Methods@#The female adult C57BL /6 mice were randomly assigned to Sham group,Ovx group and Ovx + E2 group.On the 7th day after operation,Ovx + E2 group was subcutaneously injected with 17 β-estradiol ( E2 ) for 4 weeks.Then another 48 female adult C57BL /6 mice were randomly divided into Sham group,Sham + MnTBAP group,Ovx group and Ovx + MnTBAP group.After operation for one week,MnTBAP was injected into the hippocampus of mice in Sham + MnTBAP group and Ovx + MnTBAP group.The depression-like behaviors of the mice were monitored by sucrose preference test and forced swimming test.Then the mice were decapitated,and the hippocampus samples were collected.Mitochondria of hippocampus were isolated using mitochondria fractionation kit.The concentrations of adenosine triphosphate (ATP) , reactive oxygen species ( ROS) and mitochondrial membrane potential were determined,respectively. @*Results@#Compared with Sham mice,Ovx showed a decrease in the percentage of sucrose consumption,an increase in immobility time and the alterations of hippocampal mitochondrial function,which were reversed by estrogen treatment. Intrahippocampal injection of MnTBAP significantly increased the percentage of sucrose consumption and decreased immobility time in Ovx mice.@*Conclusion@#Hippocampal mitochondrial dysfunction contributes to estrogen deficiency-induced depression-like behaviors.
ABSTRACT
Background@#and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). @*Methods@#We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. @*Results@#Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. @*Conclusion@#In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.
ABSTRACT
Background@#and Purpose Intravenous tenecteplase (TNK) efficacy has not been well demonstrated in acute ischemic stroke (AIS) beyond 4.5 hours after onset. This study aimed to determine the effect of intravenous TNK for AIS within 4.5 to 24 hours of onset. @*Methods@#In this pilot trial, eligible AIS patients with diffusion-weighted imaging (DWI)-fluid attenuated inversion recovery (FLAIR) mismatch were randomly allocated to intravenous TNK (0.25 mg/kg) or standard care within 4.5–24 hours of onset. The primary endpoint was excellent functional outcome at 90 days (modified Rankin Scale [mRS] score of 0–1). The primary safety endpoint was symptomatic intracranial hemorrhage (sICH). @*Results@#Of the randomly assigned 80 patients, the primary endpoint occurred in 52.5% (21/40) of TNK group and 50.0% (20/40) of control group, with no significant difference (unadjusted odds ratio, 1.11; 95% confidence interval 0.46–2.66; P=0.82). More early neurological improvement occurred in TNK group than in control group (11 vs. 3, P=0.03), but no significant differences were found in other secondary endpoints, such as mRS 0–2 at 90 days, shift analysis of mRS at 90 days, and change in National Institutes of Health Stroke Scale score at 24 hours and 7 days. There were no cases of sICH in this trial; however, asymptomatic intracranial hemorrhage occurred in 3 of the 40 patients (7.5%) in the TNK group. @*Conclusion@#This phase 2, randomized, multicenter study suggests that intravenous TNK within 4.5–24 hours of onset may be safe and feasible in AIS patients with a DWI-FLAIR mismatch.
ABSTRACT
OBJECTIVE@#To retrospectively analyze the efficacy and complications of our institution's modified nonmyeloablative allogeneic hematopoietic stem cell transplantation (NST) in treating intermediate-risk acute myeloid leukemia (AML) - first complete remission (CR1) and prognostic factors.@*METHODS@#Clinical data of 50 intermediate-risk AML-CR1 patients who underwent matched related NST at the Fifth Medical Center of Chinese People's Liberation Army General Hospital from August 2004 to April 2021 were collected, the hematopoietic recovery, donor engraftment and complications were observed, and overall survival (OS) rate, leukemia-free survival (LFS) rate, treatment-related mortality (TRM), and cumulative relapse rate were calculated. Statistical analysis of factors affecting prognosis was also preformed.@*RESULTS@#The median times for neutrophil and platelet recovery after transplantation were 10 (6-16) and 13 (6-33) days, respectively. One month after transplantation, 22 patients (44%) achieved full donor chimerism (FDC), and 22 patients (44%) achieved mixed chimerism (MC), among whom 18 cases gradually transited to FDC during 1-11 months, 4 cases maintained MC status. The overall incidence of acute graft-versus-host disease (aGVHD) was 36%, with a rate of 18% for grade II-IV aGVHD and a median onset time of 45 (20-70) days after transplantation. The overall incidence of chronic GVHD (cGVHD) was 34%, with 20% and 14% of patients having limited or extensive cGVHD, respectively. The incidence rates of infections, interstitial pneumonia, and hemorrhagic cystitis were 30%, 10%, and 16%, respectively. The 5-year OS rate, LFS rate, TRM, and cumulative relapse rate were 68%, 64%, 16%, and 20%, respectively. The increase of the number of CD34+ cells infused had shortened the recovery time for neutrophils and platelets (r =0.563, r =0.350). The number of CD34+ cells infused significantly influenced the occurrence of extensive cGVHD (OR =1.36, 95%CI : 1.06-1.84, P =0.024).@*CONCLUSION@#Modified NST is effective in treating intermediate-risk AML-CR1 patients, however, further expansion of sample size is needed to study prognostic factors.

Background@#and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. @*Methods@#We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). @*Results@#There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. @*Conclusions@#During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.
ABSTRACT
The application status of acupuncture and moxibustion therapy for assisted reproductive field in the United States was analyzed, and the existing problems and future development directions were discussed. According to the survey on the 456 websites of assisted reproductive clinic in the United States mentioned in the report of U.S. Centers for Disease Control and Prevention (CDC), 111 clinics among 456 assisted reproductive clinics recommend and used acupuncture and moxibustion therapy, accounting for 24.3%. Acupuncture and moxibustion therapy had obvious effect, good safety and low cost, and the assisted reproductive institutions in the United States had a high degree of application and recognition to acupuncture and moxibustion therapy. However, some problems, such as immature treatment scheme, unclear mechanism and imperfect insurance policies, still existed. In the future, the advantages of Chinese traditional acupuncture and moxibustion should combine with international modern assisted reproductive technology, and multi-center and large-sample clinical randomized controlled trials and basic experimental research on the mechanism of acupuncture and moxibustion for assisted reproduction should be carried out.

OBJECTIVE@#To compare the clinical efficacy between open and arthroscopic Latarjet procedure in the treatment of anterior shoulder instability by using Meta-analysis.@*METHODS@#Search PubMed, Medline, Embase, Cochrane, China National Knowledge Infrastructure(CNKI), Wanfang database, China Biological Literature system(CBM) and VIP database. Review all retrospective or prospective cohort studies and randomized controlled trials on open and arthroscopic Latarjet procedure for anterior shoulder instability. Binary variables (postoperative recurrence rate, incidence of intraoperative and postoperative complications) and continuousvariables [shoulder external rotation range of motion, Walch-Duplay score, Rowe score, WOSI score, postoperative visual analogue scale (VAS), postoperative anxiety degree and operation time] were selected for analysis. NOS bias risk assessment criteria (recommended by Cochrane collaboration Network) were used to evaluate the literature quality of retrospective or prospective cohort studies, and modified Jadad scale was used to evaluate the quality of randomized controlled trials. Literature screening, literature quality evaluation and data extraction were carried out independently by two observers. RevMan 5.3 software was used for Meta analysis.@*RESULTS@#(1)A total of 9 studies were included, including 8 retrospective cohort studies and 1 prospective cohort study. A total of 956 patients were included in this study, including open Latarjet procedure(@*CONCLUSION@#The arthroscopic Latarjet stabilisation shows satisfactory and comparable results to open procedure, and the postoperative recurrence and complication rates are low in both group. Both open and arthroscopic Latarjet procedure are reliable surgical procedures in the treatment of anteriorly shoulder instability. Arthroscopic procedure has longer learning curve than open procedure, the doctors may either choose arthroscopic or open Latarjet procedure based on personal skills and preference, as well as the patient's condition. However, all the literatures included in this study are cohort studies with low level of evidence. The research lack randomized controlled trials, and small sample size is small. In the future, randomized controlled studies with large sample size and high level of evidence are still needed to determine the efficacy difference between the two.

Objective: To analyze the effect of acupuncture versus hormone replacement therapy (HRT) for premature ovarian insufficiency (POI). Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Web of Science, Cochrane Library, PubMed, and Excerpta Medica Database (EMBASE) were searched up to January 31st, 2019 to identify randomized controlled trials (RCTs) evaluating the effect of acupuncture for POI. The primary outcome was the level of basal serum follicle- stimulating hormone (FSH). Secondary outcomes included serum levels of luteinizing hormone (LH), estradiol (E2) and anti-Müllerian hormone (AMH). Two authors extracted data independently and assessed the risk of bias and the methodological quality using the Cochrane's tool. Meta-analysis was conducted by RevMan version 5.3. Results: Eight eligible RCTs with a total of 496 POI patients were included in the meta-analysis. The pooled results showed that there was a significant reduction in the basal serum FSH level (MD=-5.82, 95%CI:-9.76 to -1.87, I2=82%, P=0.004) and a remarkable elevation in the basal E2 level (SMD=0.93, 95%CI: 0.34 to 1.52, I2=88%, P=0.002) in the acupuncture group when compared with the control. Subgroup analysis showed that compared with HRT, a significant decrease in the FSH level was observed in both acupuncture alone (MD=-4.53, 95%CI:-8.96 to -0.10, I2=73%, P=0.04) and acupuncture plus HRT (MD=-9.60, 95%CI:-17.60 to -1.61, I2=50%, P=0.02), while a remarkable elevation of E2 was only found in acupuncture plus HRT (SMD=1.43, 95%CI: 1.03 to 1.82, I2=0%, P<0.00001). There was no significant difference in the LH level between acupuncture and HRT (MD=-3.16, 95%CI:-9.41 to 3.10, I2=0%, P=0.32), only one trial reported AMH, and no significant difference was found between acupuncture and HRT. Conclusion: The present study indicated that acupuncture had an advantage over HRT in reducing serum FSH level and increasing serum E2 level in women with POI. However, evidence supporting the finding is limited due to the small sample size, potential methodological flaws and significant heterogeneity. Hence, this conclusion still needs to be verified by high-quality RCTs.

Objective:Astragalus polysaccharide (APS) was used in combination with ionizing radiation (IR) to investigate the mechanism of APS on the radiosensitivity of human nasopharyngeal narcinoma CNE-1 cells and the epithelial-mesenchymal transition (EMT). Method:Cell counting kit-8 (CCK-8) was used to detect the cytotoxicity of different concentrations of APS (0,6.25,12.5,25,50,100,200 g·L-1) on CNE-1 cells. Colony formation assay was used to calculate the survival fraction (survival fraction, SF) of CNE-1 cells treated with 12.5 g·L-1 APS combined with different radiation doses (0,2,4,6 Gy). The linear quadratic equation mathematical model (LQ) was used to draw the radiosensitivity curve according to SF value. Cell scratch and transwell chamber test were used to detect the migration and invasion ability of cells in each group. The apoptosis of cells in each group was detected by flow cytometry, Western blot was used to detect the expressions of EMT markers, apoptosis markers and protein kinase B/extracellular regulated protein kinases (Akt/ERK) pathway proteins in each group. Result:The results of colony formation assay and radiosensitivity curve showed that the combination of non-toxic dose of 12.5 g·L-1 APS and radiation dose of 4 Gy could significantly increase the radiosensitivity of CNE-1 cells. Compared with blank group and IR group, APS combined with IR could significantly inhibit the migration and invasion of CNE-1 cells (P<0.05), and increase the rate of apoptosis (P<0.05). In addition, compared with the blank group and the IR group, APS combined with IR could significantly down-regulate the expressions of N-cadherin, p-Akt and p-ERK, and significantly up-regulate the expressions of E-cadherin, Bax and Caspase-3 (P<0.05). Conclusion:APS combined with IR can inhibit the migration and invasion of CNE-1 cells, and increase the apoptosis induced by radiotherapy, which may be related to the inhibition of EMT and Akt/ERK pathway.

The optical-magnetic bimodal molecular probes were synthesized by substitution reaction, hydrolysis reaction, coupling reaction and complex reaction with metal respectively. For the improved route, the total yield could reach 34.6% which was higher than the original route (18.0%). The structures of those compounds were identified by 1H nuclear magnetic resonance, 13C nuclear magnetic resonance, and mass spectrometry. The improved route could avoid the uncontrollable disadvantage of the substitution reaction, this process could reduce the formation of impurities and made the purification process easier, and in the aspect of purification and separation, the preparative high-performance liquid chromatography with less sample loading and high cost was improved to a column chromatography with many sample loads and being easy to operate. Therefore, the use of column chromatography could be more conducive to mass production of the optical-magnetic bimodal molecular molecular probe.@*CONCLUSION@#The improved synthetic route improves the controllability of the reaction conditions and makes it easier to purify and separate the compounds. At the same time, the improved synthetic route can increase the total yield significantly. The optical-magnetic bimodal molecular probe can combine the living magnetic resonance imaging with the in vitro optical imaging to realize the dual synchronous detection of magneto-optics, so that the detection results of the living magnetic resonance imaging and the in vitro optical imaging are mutually verified. In other words, this synthetic optical-magnetic bimodal molecular probe will make the experimental results more accurate and reliable. In subsequent biological experimental studies, the optical-magnetic bimodal molecular probe can be applied to related research of brain structure and function, and the probe can be used for the brain-related diseases researches, such as brain tumors. after intravenous administration, and thus the optical-magnetic bimodal molecular probe can play an important role in medical treatment of brain tumors and cerebrovascular diseases.

The aim of the present study was to investigate the effect of lipoxin A4 (LXA4)pretreatment on cognitive function of aged rats after global cerebral ischemia reperfusion,and to explore its possible mechanism.Thirty-six aged male Sprague-Dawley rats were randomly divided into three groups (n=12 each):sham-operation group (S group),global cerebral ischemia reperfusion group (I/R group) and LXA4-pretreatment group (L group).The rat model of global cerebral ischemia reperfusion was established by occlusion of the bilateral common carotid artery with hypotension.The cognitive function of rats was determined by a step-down type passive avoidance test and Morris Water Maze test on the third day after reperfusion.Rats were sacrificed after Water Maze test and the pathological changes ofhippocampal CA1 region were observed and the related inflammatory mediators were determined.As compared with S group,the escape latency in I/R group was prolonged from the first day to the fifth day,while that in L group was prolonged from the first day to the third day.The retention time in I/R group and L group in the first quadrant was shortened.The reaction time,frequency of reaction mistake and frequency of escape mistake in I/R group increased,and the latent period shortened.The frequency of escape mistake in L group increased,and the damage in the hippocampal CA1 region of I/R group and L group was obvious.The levels of S-100β,TNF-α,IL-lβ,IL-10 and NF-κB in I/R group and L group increased.As compared with I/R group,the escape latency in L group was shortened from the first day to the fifth day,and the retention time in the first quadrant prolonged.The reaction time,frequency of reaction mistake and frequency of escape mistake in L group decreased,and the latent period prolonged.The damage in the hippocampal CA1 region of L group was alleviated as well.The levels of S-100β,TNF-α,IL-1β and NF-κB in L group decreased,and those of IL-10 increased.It can be concluded that LXA4 pretreatment can improve the cognitive function in aged rats after global cerebral ischemia reperfusion probably by inhibiting the inflammatory reaction.

ABSTRACT
The present study was aimed to analyze the association rules of Fufang Kushen injection in combination with other modern medications in treating lung cancer based on the electrical medical records in real world clinical situations extracted from hospital information system in Institute of Basic Medical Sciences, China Academy of Chinese Medical Sciences, and provide reference for improving rationality of clinical drug use and exploring the prescription rules as well as subsequent in-depth analysis. The electrical medical records of the hospitalized patients using Fufang Kushen injection for lung cancer were extracted to analyze the frequency distribution characteristics in combined application with western medicine, and Apriori algorithm was used to analyze the specific association rules in combined drug use. A total of 49 597 patients were included in the study. The commonly combined modern medications included 5-HT receptor blockers, antibiotics, chemotherapy drugs, antitumor immune regulating drugs, glucocorticoid drugs and analgesics, which was usually applied in combination with traditional Chinese medications such as those for removing blood stasis, spleen and stomach nourishing drugs, Qi-regulating agent, heat-clearing and detoxifying prescriptions, laxative and Qi invigorating agent in clinical treatment. The results revealed that the distribution characteristics in combined application and association combinations of Fufang Kushen injection had specific rules, consistent with the clinical orientation of this drug in treatment of lung cancer. Such results may provide reference for reasonable application of Fufang Kushen injection in clinical treatment.
ABSTRACT
Objective To analyze the etiological or associated factors and the treatment of patients with atrial fi brillation in high altitude areas in Tibet. Methods The clinical data of atrial fi brillation patients hospitalized in our hospital during January 2012 to Jane 2016 were analyzed retrospectively. Results (1) A total of 442 patients (male:female,1.2:1) were included in the study with ages of 30-96(65.9±12.3) years. The percentages of paroxysmal, persistent and permanent atrial fi brillation were 14.9%, 69.2%, and 15.8% respectively. The associated factors of atrial fi brillation included hypertension (53.4%), rheumatic heart disease (7.5%),chronic mountain sickness (10.6%), coronary heart disease(5.7%), hyperthyroidism (6.1%) and diabetes (9.0%).(2)Only 42 patients (9.5%) had evaluation with CHADS2score during hospitalization and actually 74.6% patients scored≥2. Twenty-one patients were restored to sinus rhythm during hospitalization and no patients had radiofrequency ablation.Conclusions The associated factors of atrial fi brillation in high altitude areas are similar to other areas. Thrombosis risk evaluation and anticoagulation therapy was not sufficient. Rhythm control rate was low and development of radio frequency ablation therapy should be considered.
