BACKGROUND: It is thought in traditional Chinese medicine that "the head is the residence of intelligence", "the head is the leader of body, and the focus of the spirit". Therefore, scalp electro-acupuncture can induce resuscitation, relieve mental confusion, dredge the meridian and eliminate the depression in treatment of post-stroke depression.OBJECTIVE: To observe the curative effect of head acupuncture on poststroke depression.DESIGN: Randomized controlled and single blind evaluationSETTING: Department of Acupuncture and Moxibustion, Nanfang Hospital of Southern Medical University; College of Acupuncture and Massage,Guangzhou University of Traditional Chinese Medicine.PARTICIPANTS: Totally 90 patients with post-stroke depression were from Affiliated Nanfang Hospital and,Zhujiang Hospital of Southern Medical University, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine were recruited. The Score of all the patients in Hamilton Rating Scale for Depression (HRSD) were ＞ 20. Ninety patients were randomly divided as scalp acupuncture group (n=46) and routine acupuncture group (n=44).METHODS: The patients in the routine acupuncture group were treated mainly at points of three-yang meridians of foot and hand at the hemiplegia side. The points include jianyu (LI-15) , binao (LI-14) , quchi (LI-11),shousanli (LI-10), waiguan (SJ-5), hegu (LI-4), biguan (St-31), liangqiu (St-34), zusanli (St-36), yanglingquan (GB-34), kunlun (UB-60), jiexi (St41). The above points were divided into 2 groups, 1 group each day, alternately. Even reinforcing-reducing method was used, with 30-minute needle retention, 6 successive days treatment with 1 day rest, for 6 weeks totally.The patients in the scalp acupuncture were treated with, besides the above method, scalp acupuncture. Mid-parietal line, mid-frontal line, laterofrontal lineI (both sides)were chosen. After arrival of qi, G6805 type electro-acupuncture apparatus (interrupted wave, 50 Hz,4 V) was connected, with 30-minute needle retention, 6 suocessive days treatment with 1 day rest, 6 for 6 weeks totally. HRSD was used to evaluate the status of depression before and after treatment. Stroke score was used to evaluate the curative effect of stroke.MAIN OUTCOME MEASURES: HRSD scores and curative effect of apoplexy before and after treatment of the patients in two groups.RESULTS: According to the intention treatment, all 90 patients entered the result analysis. ① HRSD score after treatment was lower than that be fore treatment in the scalp acupuncture group,and that after treatment group in the routine acupuncture group (8.55±1.73,30.61±4.02,15.04±2.33,P ＜ 0.01 ). ②There was no significant difference of the total effective rate in the two groups , but some tendency indicated the effective rate in the scalp acupuncture group was better than that in the routine acupuncture group ( 100% ,98% ,x2=1.9167 ,P ＞ 0.05).CONCLUSION: Scalp electro-acupuncture has obvious curative effect on post-stroke depression. The amelioration of melancholia has a certain promoting effect on rehabilitation of apoplexy.

BACKGROUND:Elastic stable intramedulary nailing and titanium plate fixation are two methods for the treatment of midshaft clavicular fractures. Current research about comparison of these two methods is not too much, and most of cases were retrospectively analyzed. OBJECTIVE:To compare the efficacy of elastic stable intramedulary nailing and titanium plate fixation for midshaft clavicular fractures. METHODS:The PubMed database, CBM, EMbase database, Cochrane Library database, CNKI database and Wangfang database were searched to collect the trials on midshaft clavicular fractures. The searching time ranged from the date of building to September 2015. The quality of trails was evaluated. RESULTS AND CONCLUSION:(1) Seven trials involving 512 patients were included. (2) Meta-analysis results showed the postoperative functional recovery was better in the elastic stable intramedulary nailing group than that of the plate fixation group (P< 0.01). (3) The average bone union time, operation time, incision length,intraoperative blood loss and the hospital stay of the elastic stable intramedulary nailing group were less than those of the plate fixation group (P< 0.01). (4) There were no significant differences in incidence rate of complications between two groups.(5) It is concluded that elastic stable intramedulary nailing for treating midshaft clavicular fractures is superior to the plate fixation in the efficacy. As the first choice for treatment of midshaft clavicular fractures, above conclusions are needed to be verified by large-scale multi-center randomized controled trials.

Targeting induced local lesions in genomes (TILLING) is a reverse genetics method for functional genomics research.It is possible to screen for point mutations in the populations of EMS mutagenesis with highthroughput and lowcost. EcoTILLING a method based on TILLING ,was developed for detecting multiple types of polymorphisms in germplasm collections,such as single nucleotide polymorphism,small deletion and insertion etc.Rice is a very important food crop and a model plant for genome research also. There are complete genome sequence and a lot of other bioinformatics resources about it.So the markerassisted breeding is becoming more and more important in rice breeding. Some issues based on TILLING about identifying germplasm based on gene sequence,EMS mutagenesis breeding,developing functional marker in rice breeding in future were discussed.

Background One of the features of the pathogenesis of primary angle-closure glaucoma(PACG) is anterior synechia of peripheral iris.Goniosynechialysis and combination of phacoemulsification and goniosynechialysis have been applied for the treatment of the disease recently,but the selection of operative types has great impact on clinical efficacy.Objective This study was to investigate the long-term efficacy of goniosynechialysis and combination of phacoemulsification and goniosynechialysis for the management of chronic PACG.Methods A non-randomized clinical controlled trial was designed.This clinical trial complied with Declaration of Helsinki and was approved by Medical Ethic Committee of Nanjing Medical University.Written informed consent was obtained from each patient.One hundred and ten eyes of 110 patients with chronic PACG were assigned to the goniosynechialysis group and combined operative group from March,2008 to February,2011 in Wuxi People's Hospital.180° goniosynechialysis was performed on 34 patients in the goniosynechialysis group,and phacoemulsifieation +intraocular lens (IOL) implantation + goniosynechialysis were carried out in 78 patients of the combination operative group.All the patients were followed-up for 2 years.Vision acuity,intraocular pressure (IOP),anterior chamber depth(ACD),unltrasound biomicroscopy and perimetry were recorded and compared between before and after operation.Results No significant difference was found in vision acuity between preoperation and postoperative 2 years in the goniosynechialysis group ([0.65 ± 0.15] vs.[0.45 ± 0.15]) (t =1.57,P＞0.05),but in the combination operative group,the vision acuity was significantly different between the before and after operation ([0.25±0.15] vs.[0.85 ±0.05]) (t =9.12,P＜0.001).The lOPs at 2 years after operation were (14.2±4.1) mmHgand(13.7±4.8) mmHg,respectively in the goniosynechialysis group and combination operative group and were significantly lower than(47.2 ±6.3) mmHg and(46.9±7.0) mmHg before operation(t =4.95,P＜0.001 ;t=5.03,P＜0.001).The ACD values in the goniosynechialysis group and combination operative group were(3.38±0.02)mm and (3.54±0.03) mm 2 years after operation,which were significantly increased in comparison with (1.33 ±0.24)mm and (1.56±0.37) mm before operation(t=7.65,P＜0.001;t=6.76,P＜0.001).Conclusions Both combination of phacomulsification with goniosynechialysis or 180° goniosynechialysis are effective for the treatment of PACG.Suitable operation should be alternated depending on the indicators of PACG patients.

Borneol is a traditional Chinese medicine. In the past few years, many studies showed that borneol can improve the bioavailability of other drugs, promoting drugs to cross the blood-brain barrier, so the potential drug interactions between borneol and other medicines have attracted great attention, but the influence of borneol to CYP450 and its isoforms are rarely reported. In this research, male Wistar rats were orally administered by borneol for 7 days, then the mRNA and protein expression and the activities of CYP2D were detected, we also compared the pharmacokinetic parameters of CYP2D's specific substrate between control group and borneol group. The results show that borneol (33, 100 and 300 mg x kg(-1) x d(-1)) have no significant effect on CYP2D, while the activites of CYP2D increased 1.71, 1.97 and 2.89 times comparing to the control group. At the same time, borneol (300 mg x kg(-1) x d(-1)) caused the C(max) decreased 10.6% (P > 0.05), AUC(0-∞) decreased 27.5% (P < 0.01), CL/F increased 41.1% (P < 0.01), V(z)/F increased 23.1% (P > 0.05) of dextromethorphan. Our data provided that borneol speed up dextromethorphan's elimination in vivo. Since the activity of CYP2D can be induced by borneol, the metabolic interactions might happen when borneol and the substrate drug CYP2D are used together.
