Objective To investigate the correlation of the plasma homocysteine level and serum B/apolipoprolionAl(ApoB/ApoAl) radio with cerebral vascular stenosis in patients with cerebral infarction.Methods 184 patients with cerebral infarction experienced cerebral digital substraction angiography (DSA) were selected.Among them,158 patients with cerebrovascular stenesis and 26 patients without stenosis were included.Three groups were categorized by distribution of artery lesion sites:isolated intracranial artery stenesis ( n =48 ),isolated extracranial artery stenosis( n =60) co-existing of intracranial and extracranial artery stenosis( n =50).The correlation analysis was made between the levels of Hcy and ApoB/ApoAl with cerebral vascular stenosis in patients with cerebral infarction.Results ( 1 ) The proportion of subjects with high level of plasma homocysteine was significantly higher in patients with cerebrovascular stenosis than those without[( 16.9 ±8.1 ) μmol/L vs (8.6 ±4.6) μmol/L,P ＜0.001 ;40％ vs 0,P ＜0.01].The proportion of subjects with high level of ApoB and ApoB/ApoA1 ratio was significantly higher in patients with cerebrovascular stenosis than those without ApoB [( 1.02 ± 0.25 ) vs ( 0.86 ± 0.22 ) g/L,P ＜ 0.01],ApoB/ApoAl ratio [( 0.94 ± 0.50) vs ( 0.64 ± 0.21,P ＜ 0.01 )].(2) For the different groups of artery lesion sites,the proportion of subjects with high level of plasma homocysteine was not significantly different[( 16.1 ± 8.5 )mml/L、( 17.0 ± 8.9 ) mmol/L、( 16.7 ± 8.7 ) mmol/L,P ＞ 0.05],the proportion of subjects with ApoB/ApoAl ratio was not significantly different [0.98 ± 0.45,0.93 ± 0.48,0.96 + 0.50,P ＞ 0.05].(3) Based on multivariable stepwise Logistic regression model,the increased level of Hcy( OR =1.146,95％ CI:1.021 ～ 1.287 ;P =0.021 ),the increased level of ApoB/ApoAl ( OR =4.71,95 ％ CI:1.70 ～ 14.20,P =0.005 ),the increased level of ApoB ( OR =4.50,95 ％ CI 为 1.62 ～ 12.80,P =0.007),the increased level of Cho ( OR =2.406 ;95％ CI:1.145 ～ 5.055 ; P =0.023 ),the decresed level of HDL( OR =0.089,95％ CI:0.014 ～ 0.551,P =0.017 ) were all risk factors.Conclusion High level of plasma homocysteine and ApoB/ApoAl were both independent risk factors for cerebral vascular stenosis.

To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Objective To explore the diagnostic value of spiral CT for the intestinal obstruction of unknown causes.Methods The CT findings of 115 intestinal obstructive patients with unknown causes were analyzed retrospectively.Results Of the 115 patients,the diagnosis of intestinal obstruction was comfirmed by CT in 110 cases patients,the correct diagnostic rate was 95.7%.Conclusions Abdominal CT is a rapid、simple and effective means for diagnosis of the location、cause and degree of obstruction in cases of intestinal obstruction with unknown cause.It can act as an important basis for the treatment program by doctors.

In this study, the embryological characters of Pterocypsela formosana (Asteraceae) were investigated with the traditional paraffin section methods. The anther has 4 sporangiates, the anther wall development follows the dicotyledonous type and comprises of an epidermis, endothelium, a middle layer and a single-layered tapetum, the tapetum belongs to glandular type. Meiosis of the microspore mother cells is of the simultaneous type, for the formation of mostly tetrahedral tetrad, the mature pollen grains are 2 celled. The ovary is bicarpellate, unilocular, one ovule and basal placenta, the ovule is unitegmic, tenuinucellate, inverted campylotropous and with developed endothelium, archesporial cell of megaspore differentiates immediately below the nucellar epidermis and functions as megasporocyte after development and belongs to tenuinucellate ovule type. The megasporocyte undergoes meitotic to form a liner tetrad, only one chalazal megaspore becomes the functional megaspore which forms female gametophyte including 7-celled and 8-nucleated after three successive mitosis, the female gametophyte is of the Polygonum type. Two polar nuclei melt into a secondary nuclei before fertilization, the chalazal antipodal cells are ephemeral and degenerate shortly after forming. Fertilization is porogamous and belongs to premitotic type of syngamy. The division of the primary endosperm nucleus is earlier than the zygote, the endosperm is of the nuclear type with the presence of haustoria, and the embryogeny belongs to asterad type chicory variant. The developed suspensor on early stage has important significance to the embryo development.

ObjectiveTo compare the real-time analgesic effects between two different groups of acupoints in treating primary dysmenorrhea, for providing objective evidences for optimizing the treatment protocol for primary dysmenorrhea.MethodSixty eligible patients with primary dysmenorrhea were randomized into 3 groups: group A received acupuncture at Sanyinjiao (SP6), group B received acupuncture at Sanyinjiao and Guanyuan (CV4), and group C as a blank control group, 20 cases in each group. Visual Analogue Scale (VAS) was observed prior to the acupuncture treatment, after the insertion of the needles, and after removal of the needles in the three groups.ResultThe VAS scores changed significantly in group A and B after intervention (P<0.05); there was no significant difference in comparing the VAS score between group A and B after intervention (P>0.05).Conclusion Acupuncture at Sanyinjiao alone and acupuncture at Sanyinjiao and Guanyuan both can produce analgesic effect at the attackof primary dysmenorrhea. However, for optimizing the treatment protocol, selecting Sanyinjiao alone will be enough.

Objective:To examine the plasma soluble interleukin 2 receptor (sIL-2R)and the expression of IFN-γR in helper T (Th)cells in peripheral blood of patients with recurrent oral ulcer(ROU).Methods:The peripheral blood was obtained from 21 pa-tients in active stage of ROU and 21 healthy controls.Flow cytometry was used to detect the quantity of IFN-γR in CD +4 T cells,ELISA was used to detect the level of sIL-2R.Results:The expression of IFN-γR in CD +4 T cells and sIL-2R content in plasma of the patients with ROU were significantly higher than those in the healthy controls(P <0.05).Conclusion:Over expression of IFN-γR in CD +4 T cells and sIL-2R in peripheral blood may be related to the genesis of ROU.

Objective To explore the application of B-mode intra- and post-operative ultrasound in patients with traumatic brain injuries. Methods B-mode intra- and post-operative ultrasound were performed 35 times in 24 patients, including 7 times of intra-operation in 7 patients and 28 times of post-operation in 17 patients. Results During operation epidural hematomas in 3 cases as well as intracranial hematomas in 2 cases, subdural hematomas in 1 case, diffused brain swelling in 1 case were found. After operation epidural hematomas were examined in 4 cases as well as subdural hematomas in 1 case, delayed intracranial hematomas in 6 cases, scattered contusion and laceration of the brain in 12 cases, acute obstructive hydrocephalus in 1 case, and subdural hydroma in 4 cases. Six cases underwent operations again because of delayed hematomas, contusion and laceration of the brain. B-mode ultrasound was compared with CT scan and the total coincidence rate was 85.4%.Conclusions B-mode ultrasound is helpful to examine delayed hematomas and other emergent complications. It may save time and may improve rescue rate and has a good coincidence with CT scan. B-mode ultrasound may be widely used as a routine way in neurotrauma ICU.

Objective To investigate the echocardiographic features and clinical significance of prenatal diagnosis of total anomalous pulmonary venous connection (TAPVC). Methods Fetal echocardiographic images of 13 fetuses with TAPVC conifrmed by pathology or postnatal echocardiography were reviewed. Echocardiographic features and clinical signiifcance of prenatal diagnosis of TAPVC were summarized. Results Twelve fetuses with TAPVC were diagnosed prenatally by fetal echocardiography, including seven cases of supracardiac type, three cases of infracardiac type and two cases of intracardiac type. The common echocardiographic characteristics of 12 fetuses with TAPVC included slightly size discrepancy of left heart and right heart, large foramen ovale with increased shunting at the atrial level, increased distance between left atrium (LA) and descending aorta, absent insertions of pulmonary veins in the LA, presence of pulmonary venous conlfuence on the top of LA and dilatation of vessels where pulmonary venous conlfuence drained. One case was missed prenatally and intracardiac type TAPVC was diagnosed by postnatal echocardiography. Among the 13 cases, three were isolated and the other ten were all in association with other abnormalities. Conclusions There are fetal echocardiographic characteristics of TAPVC. Fetal echocardiography plays an important role in prenatal diagnosis of TAPVC.

Objective To investigate the effect of Tongxinluo on carotid artery stenosis,and the levels of high sensitive C reactive protein(hs-CRP) and D-Dimer in patients with cerebral infarction.Methods 168 patients with cerebral infarction treated in this hospital from June 2014 to June 2015 were randomly divided into experimental group and control group,with 84 cases in each group.The patients in both group received routine treatment.In addition to that,patients in the experimental group also used Tongxinluo capsule for 6 months as a course of treatment.After a course of treatment,Doppler ultrasound diagnosis instrument was used to detect carotid arterial intima-media thickness,plaque area and carotid artery stenosis rate.Hs-CRP and D-Dimer levels were also detected.Results After treatment,the carotid arterial intima-media thickness,plaque area and carotid vascular stenosis rate in two group were significantly decreased(P<0.05),but the three indicators in experimental group were decreased more significantly(P<0.05).After a course of treatment,the levels of D-Dimer and hs-CRP in peripheral blood of the two groups were significantly decreased(P<0.05),but the content of D-Dimer and hs-CRP was much lower in the experimental group(P<0.05).Conclusion Tongxinluo treatment could effectively reduce the level of hs-CRP and D-Dimer in patients with cerebral infarction,and alleviate the carotid artery stenosis,which might be worthy of clinical application.
