Result of the present study showed that Anoectochilus roxburghii (Wall. )I,indl. is the genuine speciescurrently used as folk medicine, while A, formosanus Hayata. is a different species with the same name ofJinxianlian. trhe distribution and ecological environment of Jinxianlian were described and an index of eightspecies of Anoectochilus Bl. were listed to distinguish their maln eharacteristic differences.

In order to understand the students'knowledge mastery,assess teaching effects and improve the quality of teaching,this article analyzed the test papers of Neurology among the five-year program clinical medicine students of Grade 2006 in our College.The results indicated that the mean score of the exam was 87.29 with a standard deviation of 7.90.The distribution was negatively skewed.The degree of difficulty was 0.78 and the discrimination is 0.19.The reliability was 0.59.It demonstrated that the test papers had a good reliability,the design of the test papers was too easy and could not reasonablely discriminate the degree in evaluating the students'mastery of the course.Therefore,we shoud pay attention to appropriate difficulty and ensare quality in preparing test papers to scientifically evaluate teaching quality.

Objective To evaluate the therapeutic results of percutaneous transhepatic stent angioplasty for portal vein stenosis following liver transplant.Methods From 2005 to 2007,7 patients developed portal vein stenosis following liver transplant.Percutaneous transhepatic stent angioplasty of the portal vein was performed in all patients.The therapeutic results were monitored by clinical follow-up and imaging examination.Results In seven patients,the percutaneous transhepatic stents were placed successfully.The follow up period ranged from 3 months to 34 months.Portal venous patency Was maintained in six patients(one patient died due to hepatic arterial thrombosis and ischemic insult to bile duct at three months following the stent placement).No complications due to stent angioplasty occurred.Conclusion Percutaneous transhepatic stent angioplasty is an effective and safe method for treatment of portal vein stenosis following liver transplant.

Objective:To evaluate the clinical value of tissue doppler imaging Tei index in evaluating the degree of myocardial injury, right cardiac function after neonatal asphyxia.Methods:From March 2018 to May 2019, 62 cases of neonatal asphyxia hospitalized in the undergraduate department of Yiwu Central Hospital were classified as asphyxia group.According to Apgar score of birth, they were further divided into 41 cases of mild asphyxia group, 21 cases of severe asphyxia group.And 30 healthy full-term neonates delivered in our Hospital during the same period were selected as normal control group.The Newborn's Tei index, as well as the different severity asphyxia neonatal serum myocardial injury indicators[amino terminal brain natriuretic peptide(NT-proBNP), troponin(cTn-Ⅰ), creatine kinase isoenzyme(CK-MB), lactate dehydrogenase(LDH)], ultrasonic right heart function parameters[right ventricular ejection fraction(RVEF), E, A value and E/A ratio] were compared.Pearson test was used to evaluate the correlation between Tei index, myocardial injury indicators and right cardiac function parameters in neonatal asphyxia cases.Results:The Tei index of the asphyxiation group was (0.38±0.05), which was higher than (0.27±0.04) of the control group ( t=10.521, P<0.05), and the Tei index of the severe asphyxiation group was (0.43±0.06), which was higher than (0.34±0.05) of the mild asphyxiation group ( t=6.264, P<0.05). In neonatal asphyxia cases, the NT-proBNP, cTnI, CK-MB, LDH levels in the severe asphyxia group were (1 164.27±231.64)ng/L, (0.33±0.05)μg/L, (27.11±3.65)U/L, (298.20±37.57)U/L, respectively, which were higher than those in the mild asphyxia group [(590.38±73.91)ng/L, (0.25±0.04)μg/L, (18.36±2.34)U/L, (200.71±24.39)U/L] ( t=14.576, 6.839, 11.463, 12.338, all P<0.05). The ultrasonic RVEF level, E/A ratio in the severe asphyxia group were (52.94±6.10)%, (0.94±0.11), respectively, which were lower than those in the mild asphyxia group [(56.83±5.97)%, (1.02±0.13)] ( t=2.411, 2.547, all P<0.05). Correlation analysis found that Tei index was positively correlated with NT-proBNP, cTn-Ⅰ, CK-MB, LDH levels, and negatively correlated with RVEF level, and positively correlated with E/A ratio in neonatal asphyxia cases( r=0.745, 0.598, 0.703, 0.665, -0.711, -0.692, all P<0.05). Conclusion:Abnormal increasing of Tei index in neonatal asphyxia cases can objectively reflect the extent of myocardial injury and right heart function decline in children.
