In recent years,with the increase of epidemics events with CV-A as the main pathogen,the studies focusing on the CV-A infection have attracted more attention. In this paper,we comprehensively review the basic characteristics,pathogenesis and potential antiviral drugs of CV-A.

Objective To investigate the application of noninvasive correction of congenital auricle defor-mity,and to analyze the cure rate and the causes of incidence of complications. Methods From January 2015 to December 2016,33 patients with unilateral or bilateral congenital auricle deformities were treated with non-surgi-cal correction technique in the Plastic Surgery Department of Guangzhou General Hospital. When the treatment was completed,the VAS score was used to assess the satisfaction of the patient's parents. Results From January 2015 to December 2016,33 patients(53 ears)received noninvasive treatment of the ear deformity correction system. The average age of the patients was(63.5 ± 41.3)days,the average treatment time was(41.6 ± 15.4)days,and the average parental satisfaction was 3.76 ± 0.93(total score:5 points). Significant difference was observedin auri-cle morphology data between pre- and post- treatment ,except for cranioauricular angle(P < 0.05). Conclusions In this study,the cure rate for non-surgical correction was good,however,the satisfaction of treatment decreased with age.The most common complication of treatment was auricle skin damage. The reasons of causing complica-tions maybe the age-induced reduction of ear cartilage elasticity which brought great pressure on the ear ,and the increase of the treatment time.

BACKGROUND: Levodopa substitutive therapy is essential and effective method for PD for a long time, but it can not delay the course of PD. Side effect is more and more and severe, for taking levodopa long term. It is benefit to patients to postpone the usage of levodopa or decrease the dosage of it.OBJECTIVE: To systematically investigate the curative effect of the selfmade Bushenpingchan formula combined with madopar on pathogenetic condition of PD patients after onset.DESIGN: Randomized controlled observation.SETTING: Senile Disease Research Center, Xuanwu Hospital, Capital University of Medical Sciences.PARTICIPANTS: Seventy patients diagnosed as having PD were recruited from the Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine between December 1999 and May 2002. Inclusive criteria: The patients must be diagnosed as PD finally; ②be at 1.5-4 grade of modified Hoehn & Yahr measuring scale; ③less than 80 years old; ④The Traditional Chinese Medicine (TCM) diagnosis was deficiency of liver and kidney. Exclusive criteria: ①secondary PD; ②accompanying with other sever central nervous system diseases. ③patients with severe diseases of heart,lung, kidney or multi-viscera-failure; ④mental sickness patients; ⑤drug and alcohol abuse; ⑥severe adverse effect.METHODS: Totally 70 patients were divided into two groups based on the proportion of one to one: There were 35 patients in treatment group containing 22 males and 13 females. The average age was (67.9±16.5)years. There were 35 patients in control group including 25 males and 10females. The average age was (65.5±16.5) years. There was no significant difference in their general condition. Patients in the control group received 62.5-500 mg madopar (250 mg in each pill), 2-4 times a day (to change the dose according to patients' condition). The patients in the treatment group were given with 62.5-500 mg madopar (250 mg in each pill), 2-4times a day orally and 200 mL self-made Bushenpingchan formula (twice a day) in addition, which was composed of 20 g tuber fleeceflower root, 1 g hairy deerhorn, 10 g tall gastrodia tuber, 15 g gambirplant, 12 g Chinese thorowax root, 15 g twolobed officinal magnolia bark, twice a day. The course of medication was 3 month in patients of the two groups. The patients were determined with unified Parkinson disease rating scale (UPDRS) before treatment and at weeks 2, 4, 8 and 12 after treatment, respectively. The symptoms in traditional Chinese medicine after treatment were measured. The dose of madopar before and after medication as well as the adverse effect were observed.MAIN OUTCOME MEASURES: Score of UPDRS before treatment and at weeks 2, 4, 8 and 12 after treatment in patients of the treatment group and control group; the dose of madopar before and after treatment and the adverse effect after treatment.RESULTS: Total effective rate was 69% and 51% in the treatment group and control group, respectively after treatment. There was no significant difference in therapeutic efficacy (x2=0.86, P=0.222 3). ①The score of UPDRS reduced significantly 8 weeks after treatment in the treatment group as compared with that before treatment (t=2.18 ,P ＜ 0.05). ②The daily dosage decreased in the patients of the treatment group after treatment as compared with that before treatment, which had significant difference (t =2.862 8,P ＜ 0.01 ). The daily dosage in the patients of control group had insignificant difference with that before treatment (t=2.320 3,P ＜ 0.01 ). ③There were 2 cases with lightly dry mouth, nausea, dizziness,which could relieve two weeks later in the treatment group; 5 patients with nausea and 2 patients with light dizziness in control group, which could relieve. The blood pressure had no significant change in the two groups before and after treatment.CONCLUSION: The Chinese medicine Bushenpingchan formula combined with western medicine can decrease the UPDRS score in PD patients,can improve the syndromes in Chinese medicine.

Objective To investigate the effects of exposure of gravid rats to the persistent organic pollutants (POPs), methoxychlor (MXC), on the placenta and their progeny during gestation periods. Methods According to different dosage levels of MXC [16, 32, 64 and 0 mg/(kg?d)], forty female SD rats aged 3-month were randomly divided into low-dosage group, mid-dosage group, high-dosage group and control group, with 10 animals for each. All the rats received intraperitoneal injection of MXC for 20 days. The influence of MXC on placenta of gravid rats and their progeny were observed in all aspects. Results With the increase in MXC dosage, intense changes were found in the rats, including an inerease in the number of corpus luteum of ovary, the number of nidation, fetal death and merging fetal (P

Cell culture, Fluo-3 AM loading and laser scanning confocal microscope(LSCM), flow cytometer(FCM)and Western blot were employed to detect the regulation effect of retinoic acid on signal transduction pathway of gap junction gene connexin cx43 in HeLa. The results showed that after treated by ATRA , the second intercellular messenger [Ca 2+]i was much higher in HeLa cells(58.16 nmol/L)than in untreated cells(35.73 nmol/L). A detectable and up-regulation of Cx43 in 43kDa protein in HeLa cells increased from 1.9% to 26.3% in RA-treated cells than in untreated cells examined by FCM and Western blot. Immunoblot showed that only the treated cells had phosphorylated Cx43 protein of 43 kDa. The results suggest that the anti-tumor effect of ATRA in HeLa might be due to up-regulation of cx43 gene and its signal transduction pathway which mediates GJIC. The decreased expression of Cx genes, and the disorder and abnormal signal transduction pathway of Cx gene should be responsible for the uncontrolled tumor cell growth.

0.05).[Conclusion]Lateral-anterior fixation with use TSRH not only has effective result in strength, rigidity and stability of the spine, but also is superior to the control group in loading-bearing ability and stability of the spine. There is no significant difference between the TSRH group and Z-plate group. But TSRH is relatively simple to operate and is cheaper than Z-plate, and has exact clinical ontcome.
