Objective:To investigate the clinical efficacy of mechanical solitaire AB stents thrombectomy combined with intra-arterial thrombolysis in the treatment of patient with acute ischemic stroke.Methods:Fifteen patients with acute ischemic stroke admitted into our hospital from August 2014 to August 2016 were treated with mechanical thrombectomy with solitaire AB stents plus intra-arterial thrombolysis.The National Institutes of Health Stroke Scale score (NIHSS) of all patients were evaluated before and after treatment to compare the clinical efficacy.The prognosis ofpatients between two groups were compared via evaluating modified Rankin score (mRS)and gelasijia coma score (GCS).Results:After mechanical thrombectomy with solitaire AB stents plus intra-arterial thrombolysis treatment,14 patients achieved complete or part recanalization,and 1 patient was terminated treatment due to vital signs instability,and the rate ofrecanalization was 93.3％.The NIHSS score of patients before treatment was 12.93± 4.25,which was much higher than that after treatment (4.33± 1.45,P＜0.05).After follow-up by 3 months,the good mRS scores were obtained in all 18 patients,including 2 patients with mRS score of 2,5 patients with 1,and 8 patients with 0.Additionally,there was no patient with re-obstruction during follow-up period.Conclusion:Mechanical thrombectomy with solitaire AB stents combined with intra-arterial thrombolysis had a good capability and safety in the treatment of patients with acute ischemic stroke.

ObjectiveTo evaluate the clinical efficacy of cutaneous branches of reverse second and third dorsal metacarpal artery fasciocutaneous flaps for repair of distal- and middle-segment finger soft tissue defects. MethodsA total of 14 patients with distal- and middle-segment finger soft tissue defects complicated by exposure of the phalanx or tendon were repaired by using cutaneous branches of second and third dorsal metacarpal artery fasciocutaneous flaps ranging between 2.0 cm × 4.5 cm and 3.0 cm × 7.0 cm.ResuitsAll of the skin flaps survived after surgery.Follow-up data during a 6-40 month period showed that the flaps exhibited a satisfactory appearance.They were not fat or clumsy,with a 2-point discrimination of 59 mm,and there was good recovery of finger function.The donor site was able to be directly sutured without dermoplasty.Pigmented linear surgical streaks appeared in the donor site.Conclusion The cutaneous branches of Second and third dorsal metacarpal artery fasciocutaneous flaps provide a good approach for the repair of distal- and middle-segment finger soft tissue defects and functional reconstruction because of convenient dissection,little trauma,sufficient use of the dorsal metacarpal artery.

AlM:To research the reasonability of current criteria on distant vision anddiopter for recruiting civil aviators in China.
METHODS: The data about distant vision and diopter of 1901 aviators, including flight majors and aviators in active service participating in physical examination of Civil Aviation Flight University of China from 2006 to 2013, were collected. ANOVA and LSD were used to compare the differences between distant vision and diopter among different groups. The Spearman correlation coefficients of distant vision (≥0. 1 vs ≥0. 3) and diopter (0. 00 to -3. 00D) were calculated.
RESULTS: The diopter of civil aviators in China increased with distant vision decreased. The correlation between distant vision and diopter ( 0. 00 to -3. 00D ) among distant vision≥0. 3's population (0. 4 CONCLUSlON: The current eye standard of recruiting civil aviators in China is reasonable to consider both distant vision and diopter, but the standard for distant vision is higher. Further research is proposed to explore the proper standard of distant vision that matches the diopter standard.

To study the chemical constituents from the the deep-sea fungus Alternaria sp. F49. Seven compounds were isolated from the EtOAc extract by using silica gel, Sephadex LH-20, ODS and HPLC methods. Based on the spectroscopic analysis, their structures were identified as (8R)-5-O-methyl-orcinotriol (1), orcinotriol (2), α-acetylorcinol (3), 3'-hydroxyalternariol 5-O-methyl ether (4), altenusiol (5), altenusin (6), and 5'-methoxy-6-methyl-biphenyl-3,4,3'-triol (7). (8R)-5-O-Methyl-orcinotriol (1) is a new phenolic compound which has never been reported in the literature. Compounds 4-7 showed strong DPPH free radical scavenging activity; whereas compounds 1-7 showed strong ABTS free radical scavenging activity.

To retrospectively analyze the clinical data of a child with congenital broncho-bile duct fistula(CBBF) in Guiyang Children′s Hospital in June 2019.A female, aged 7 years and 6 months old, patient presented cough with a large amount of yellow green mucus.The main clinical manifestation was recurrent pulmonary infection after birth.After the fistula was found by electronic bronchoscope, doctors cooperated with imaging department, anesthe-siology department and pediatric surgery department.After treatment, the child recovered and discharged.There are few reports on CBBF.This study suggested that, in view of the refractory pneumonia with recurrent pulmonary infection and yellow green sputum after birth, and that the effect of anti-infection treatment was poor, clinicians should pay attention to the CBBF, take bronchoscopy as soon as possible, and make early diagnosis by combining with imaging technology, thus formulating a reasonable diagnosis and treatment plan under multidisciplinary cooperation, so as to improve the diagnosis and treatment of this rare disease clinical diagnosis and treatment level, and reduce missed diagnosis and misdiagnosis as well.

Coronavirus disease 2019 (COVID-19) is a highly contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). More than one-third of patients with COVID-19 experience neurological symptoms, including confusion, headaches, and decreased/disordered taste. Alzheimer's disease (AD) is a slowly progressive neurodegenerative disease and the most common type of dementia. Alzheimer's disease patients are at high risk and susceptible to infection with COVID-19, which may cause severe illness and even death. There appears to be an interaction between AD and COVID-19, and on the one hand, patients with COVID-19 seem to be more likely to develop AD. AD patients, on the other hand, may be more susceptible to severe COVID-19. Therefore, understanding the common link between COVID-19 and AD may help to develop treatment strategies. Risk factors common to AD and COVID-19 are aging, ApoE ε4 allele, β-amyloid (Aβ) deposition, angiotensin-converting enzyme (ACE), neuroinflammation, oxidative stress. Here, this article focuses on the relationship between COVID-19 and AD, explores common risk factors and potential pathogenesis, and provides help for early prevention, treatment and recovery.

OBJECTIVE: To quantitatively investigate the association between the polymorphism of FokI of the VDR gene and the susceptibility of prostatic cancer. METHODS: Databases of Pubmed, EMBase, CBM, CNKI, VIP, and Wanfang Data were retrieved from the date they formed till May 2011. All randomized controlled clinical trials which matched both the inclusive criteria and exclusive criteria were subjected to meta-analysis, conducted on Revman 5.0.0 software. Stata 11.0 software was employed to process Begg's test. RESULTS: Ten studies were included. Total sample cases were 8360, with 3749 cases in the patient group and 4611 cases in the control group, respectively. The quantitative analysis showed there were no significantly differences between the polymorphism of VDR FokI alleles and the susceptibility of prostatic cancer (allele F to f: OR=1.00, 95% CI=0.94-1.06, P=0.96; genotypes FF/Ff to ff: OR=1.04, 95% CI=0.93-1.51, P=0.48; genotypes FF to Ff/ff: OR=0.97, 95% CI=0.89-1.06, P=0.53). Though one research on Indian people indicated that allele F was a risk factor for prostatic cancer, in Begg's test we observed relatively high publication bias. The subgroup analysis showed there were no significantly differences between the polymorphism of VDR FokI alleles and the susceptibility of prostatic cancer (allele F to f, white race: OR=0.91, 95% CI=0.88-1.02, P=0.17; yellow race: OR=1.09, 95% CI=0.95-1.24, P=0.22; Indian: OR=1.91, 95% CI=1.30-2.81, P=0.0009). CONCLUSION VDR FokI allele F might be a protective factor for European and American Caucasians.

Objective To assess the efficacy of HIV/AIDS prevention and control among long-distance drivers in China. Methods Based on the principles and methods of Cochrane systematic reviews, we searched literature from CBM (from 1978 to 2009), VIP (1989 to 2009) CNKI (1980 to 2009) , and MEDLINE (1950 to 2009) and also assessed the risk of bias of the included before-after studies according to Newcastle-Ottawa scale and their characteristics. Cochrane Collaboration's software RevMan 5.0 was used for Meta-analysis. Results 13 studies were included, with most of them were of low quality as having high risk of bias. (1) Knowledge index 1 :We included 7 'pre-posr'studies. Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the knowledge index 1 among long-distance drivers (RD=0.15, 95% CI:0.04-0.26). (2) Knowledge index 2: We included 10 pre-post studies, in which the results from Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the knowledge index 2 among long-distance drivers (RD = 0.24,95 %CI: 0.17-0.30). (3) Behavior index:We included 6 pre-post studies in which the results from Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the behavior index among long-distance drivers (RD=0.15,95% CI 0.10-0.19). Conclusion Current evidence demonstrated that HIV/AIDS prevention and control programs were effective.

Objective To study the distribution of rs2234693 and rs9340799 of estrogen receptor (ER)gene and the relationship between them and lipid metabolism in the Ningxia Hui group,China.Methods We used cluster sampling method to select 5 3 3 cases of Ningxia Yinchuan communities of Hui. SNP genotyping was performed using the Sequenom MassARRAY platform.Results ① The frequencies of the distribution of each genotype of rs2234693 in Ningxia Hui population were the same as those in Chinese Han and Dai,Americans, Europeans,and Japanese (P>0.05).The distribution of each genotype of rs9340799,especially AA genotype,was different from that in Europeans (P<0 .0 5 ).② The body mass index in dyslipidemia group was significantly different from that in the control group (P<0.01).③ The risk of dyslipidemia in subjects with GG genotype of rs9340799 was 2.97 times higher than that in subjects with other genotypes (OR=2.97,P<2.97 ).After adjustment of gender,age,and body mass index (BMI),estrogen level was also 2.76 times higher (OR=2.76,P<0.05).(4)The frequency of C-G in rs2234693-rs9340799 haplotype was greater than that in the control group,but without any significant difference (P>0.05).Conclusion ER genes distribution in the Hui nationality of Ningxia is significantly different from that in other races;rs2234693 has no obvious relationship with the occurrence of dyslipidemia while GG genotype in SNP rs9340799 significantly increases the risk of lipid metabolism disorders.
