AIM: To observe the clinical efficacy and safety of vincamine sustained release capsules on non- arteritic anterior ischemic optic neuropathy ( NAION) . · METHODS: Patients who were diagnosed with monocular onset NAION in acute stage from January to September 2015 were divided into two groups. Routine treatment such as steroid pulse therapy and neurotrophic treatment were given to all the patients. Vincamine was added to the treatment group patients with 30mg twice a day for 3mo. The best corrected visual acuity ( BCVA), mean deviation ( MD) of visual field, retinal nerve fiber layer ( RNFL ) , ganglion cell complex ( GCC ) , pattern visual evoked potential ( PVEP ) and OCT results were analyzed before and after the treatment. ·RESULTS:Totally 42 eyes of 42 patients were enrolled in our study. There were 27 patients in the treatment group, aged from 33 to 79 years old, the average value was 55. 55± 11. 83 years old. The control group has 15 patients, aged from 40 to 70 years old, the average value was 55. 71 ± 10. 06 years old. There were no statistical differences between the two groups in the baseline. After 3mo of the treatment, MD value of the two groups were lower compared with the baseline, the difference was statistically significant in the treatment and control group respectively (t= 2. 342, 2. 692; P = 0. 027, 0. 041). The difference of PVEP amplitude and potential of the two groups before and after the treatment were not statistically significant. The thickness of retinal nerve fiber layer and the ganglion cell complex were all lower than the baseline, and the difference was statistically significant (P<0. 001). The treatment of the two groups were both effective, the treatment group has better treatment effect than the control group. Adverse events related to the treatment of vincamine had not been found. ·CONCLUSION:Vincamine is helpful in the treatment of non-arteritic anterior ischemic optic neuropathy.

Objective To analyze the clinical characteristics of twin reversed arterial perfusion sequence (TRAP),and investigate its prenatal evaluation and clinical management.Methods Karyotype results and ultrasound data of 25 TRAP cases were retrospectively reviewed,including estimated weight and umbilical blood flow of acardiac twin,cardiac function and middle cerebral artery peak systolic velocity of pump twin.Various managements and the outcomes were analyzed.Results (1) Karyotype of amniotie fluid were tested in 16 pump twins.Mosaicism was found in 1 case (46,XX[36]/46,XY [14]).(2) According to the ultrasound evaluation,large acardia accounted for 87.0% (20/23) cases.Abundant blood perfusion (inter-twin difference of umbilical resistance index ≤0.20) was indicated in 86.4% (19/22) cases.Decompensation of cardiac function was suggested in 66.7% (10/15) pump twins.Fetal anemia of pump twin indicated by middle cerebral artery peak systolic velocity>1.5 multiples of the median was diagnosed in 75.0% (12/16) cases.(3) The acardiac twin with abundant blood perfusion was more likely to be a large acardia than those without [94.7%(18/19) vs 1/3,Fisher exact test,P=0.04]; More pump twin with large acardia tended to have cardiac decompensation than non-large acardia pump twins [83.3 % (10/12) vs 0/3,Fisher exact test,P=0.02].(4) Eleven patients chose to terminate their pregnancies after being diagnosed.In 14 cases who continue the pregnancies,the survival rate of pump twin was 64.3% (9/14).In 3 cases of non-large acardia without cardiac decompensation of pump twin,the patients selected conservative observation resulting in 2 term deliveries and 1 termination of pregnancy due to for exacerbation.Among 11 cases with large acardia,which the pump twins were complicated by cardiac decompensation or anemia,five cases selected conservative observation.One ended in spontaneous abortion; three exacerbated (one termination and two cesarean section before term with living births) ; one was stable until delivery.Another 6 cases received bipolar cord coagulation,and successful interruptions of acardiac blood flow were achieved in 5 cases among which 4 pump twins survived.Conclusions Prenatal diagnosis,cardiac function and fetal anemia of pump twin,together with the growth and blood supply of acardia are important indexes for prenatal evaluation of TRAP,on which our prompt management should be based.

OBJECTIVETo summarize the methods and experiences in surgical treatment of hemifacial microsomia.
METHODSFifty-eight cases of hemifacial microsomia that have been treated by plastic and reconstructive surgery and followed-up in our department during last 20 years have been reviewed. Every patient's characteristic was assessed by physical examination, photography, craniofacial cephalometry before planned the method of surgery. Different surgical treatments were chosen according to the side and the structures involved in the abnormalities and the severity of hemifacial microsomia, and the cases were followed up since 3 months after the treatments. The follow-up lean of midline of the lower 1/3 face with that before treatment is compared. The degrees of patients' and surgeons' satisfactions with the treatments were evaluated respectively.
RESULTSThe average angle of lean of midline of skeletal and soft tissue of the lower 1/3 face decreased 4.2 degrees and 2.9 degrees respectively after treatment. Fifty (82.6%) cases satisfied with the outcome of the surgical treatment and surgeons satisfied with 84.5% of the outcome of all the cases.
CONCLUSIONSIndividual surgical treatment based on the side and the structures involved in the abnormalities can effectively correct facial asymmetry of hemifacial microsomia.

In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.
