By reverse transcription-polymerase chain reaction (RT-PCR), an open reading frame of pathogenesis-related protein 1 (PR1) was isolated from Panax notoginseng and named as PnPR1. Molecular and bioinformatic analyses of PnPR1 revealed that an open reading frame of 501 bp was predicted to encode a 166-amino acid protein with a deduced molecular mass of 18.1 kD. Homology analysis showed that the deduced amino acid sequence of PR1 protein of Panax notoginseng had a high similarity with other higher plants had the same conservative structure domain of cysteine-rich secretory protein (CAP). The recombinant expressed plasmid pET28a(+)-PnPR1 was expressed in Escherichia coli BL21. The expression conditions were optimized by induction at different times, different temperatures, different IPTG concentrations and different giving times. The optimum expression condition was 0.4 mmol.L-1 IPTG at 28 degrees C for 20 h. The successful expression of PnPR1 provides some basis for protein purification and preparation of the monoclonal antibody.

OBJECTIVETo evaluate the efficacy and safety of three different spinal rotation manipulations for the treatment of lumbar disc herniation.

METHODSFrom September 2011 to April 2013,180 patients diagnosed as lumbar disc herniation were randomly divided into seat fixed rotation group (A), lateral position rotation group (B) and supine position rotation group (C) by using a digital table. Finally 10 patients were excluded and dropped, 170 patients were included in the study. There were 57 patients in group A, 57 patients in group B and 56 patients in group C. Baseline demographic characteristics of patients, clinical findings and indexes of health status had no statistically differences among three groups (P > 0.05). The manipulation was performed every other day, and the treatment duration for all patients was 3 weeks. Body pain (BP), Physical function (PF) in SF-36, Oswestry Disability Index (ODI) and adverse reactions were observed statistically 6 weeks, 3 months, 6 months, one year and two years after finishing treatment.

RESULTSBP, PF scores in 3 groups were significantly improved and ODI scores were significantly lower than those before treatment and the differences were statistically significant (P < 0.05); However, there was no significant difference among three groups in the BP, PF and ODI scores (P > 0.05). There were no obvious and serious adverse reactions among these groups.

CONCLUSIONBased on the theory of dislocation of bone joints in TCM, three kinds of spinal rotation manipulations can be used safely for the treatment of lumbar disc herniation, and the efficacy was similar.

The continuous cultivation of Rehmannia glutinosa causes the accumulation of phenolic acids in soil. It is supposed to be the reason of the so called "continuously cropping obstacle". In this study, phenolic acids (hydroxybenzoic acid, vanillic acid, eugenol, vanillin and ferulic acid) were degraded by the extracta of all the tested spent mushroom substrate (SMS) and the maximal degradation rate was 75.3%, contributed by extraction of SMS of Pleurotus eryngii. Pot experiment indicated that hydroxybenzoic acid and vanillin in soil were also degraded effectively by SMS of P. eryngii. The employment of SMS enhanced ecophysiology index to near the normal levels, such as crown width, leaves number, leaf length, leaf width and height. At the same time, the fresh and dry weight and total catalpol concentration of tuberous root weight of R. glutinosa was increased to 2.70, 3.66, 2.25 times by employment of SMS, respectively. The increase of bacteria, fungi and actinomycetes numbers in rhizosphere soil were observed after the employment of SMS by microbial counts. The employment of SMS also enhanced the enzyme activity in soils, such as sucrase, cellulase, phosphalase, urease and catelase. These results indicated that the employment of SMS alleviated the continuously cropping obstacle of R. glutinosa in some extent.

Background It has become a consensus about the necessity of topical administration of corticosteroid eye solutions after myopic laser-assisted in situ keratomileusis(LASIK).The glucocorticoid eye drops with good anti-inflammatory effect and less adverse effects is helpful for the repair of corneal epithelium following LASIK.Objective This study was to evaluate the clinical effects of 0.5％ loteprednol etabonate eye drops after LASIK.Methods A prospective randomized-controlled study was designed.One hundred and twelve myopia patients(224 eyes)who had received LASIK were included in this study and randomly divided into two groups,and 97 patients finished the follow-up,including 108 eyes of 54 patients in the 0.5％ ioteprednol etabonate eye drops treatment group and 86 eyes of 43 patients in the control group.0.5％ loteprednol etabonate eye drops or dexamethasone/tobramycin eye drops were administered topically to the treatment group and control group,respectively 4 times daily from postoperative day 1 through day 7 following LASIK in addition to regular basic treatment.The follow-up was performed 1 day,1 week and 1 month after LASIK.Subjective symptoms including eye pain,foreign body sensation and blurring were scored,and uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA),intraocular pressure(IOP),central corneal thickness,corneal fluorescein staining and diffuse laminar keratitis(DLK)were evaluated and compared between the two groups 1 day,1 week,and 1 month after LASIK.This clinical trial was approved by the Ethic Commission of Zhongshan Ophthalmic Center,and written informed consent was obtained from each patient before the trial.Results No drug-related ocular and systemic adverse events were found in the treatment group throughout the follow-up duration.There was no significant difference in the subjective symptom score after 1 day,1 week and 1 month(P＞0.05).At 1 week post-LASIK,the corrected actual IOP was (16.27±3.31)mmHg in the treatment group and(17.49±4.48)mmHg in the control group,with a statistically significant difference between them(t =-2.113,P =0.036).However,there was no statistically significant difference in IOP between the treatment group(15.01±3.22)mmHg and the control group(15.30±4.17)mmHg at 1 month post-LASIK(t=-0.532,P=0.595).Mild diffuse lamellar keratitis developed in 7 eyes in the treatment group and 5 eyes in the control group without a significant difference on the first day after LASIK(x2 =0.153,P =0.926).The scores of corneal fluorescein staining were not statistically different between the two groups at 1 day,1 week and 1 month postoperative(Z=-0.566,P=0.571 ;Z=-0.689,P=0.491 ;Z=-1.628,P=0.103).Conclusions 0.5％ loteprednol etabonate eye drops could effectively inhibit postoperative inflammation and low the incidence of DLK.It can lessen the risk of IOP elevation in comparison with traditional steroid eye drops.

Objective To observe the electrocardiogram changes of threatened crowds in Keshan disease (KSD) endemic area in Shandong province. Methods In 2008,inhabitants from 21 villages of Zoucheng,Sishui,Tengzhou, Yishui, Pingyi, Wulian, Juxian and Qingzhou regions were selected as subjects undergoing electrocardiogram. No less than 100 people were chosen from each village and the examination rate was not lower than 85%. Results Among the 3378 inhabitants investigated,460 cases showed abnormal electrocardiogram and the total incidence of abnormal electrocardiogram was 13.62% (460/3378). The relatively high incidence was T-wave changes,QRS low voltage and ST-T changes,the detection rate being respectively 2.69% (91/3378), 1.92% (65/3378) and 1.72% (41/3378). The highest incidence of abnormal electrocardiogram (26.76%,55/213),the intermediate(21.50%,43/200) and the lowest(5.50%,12/218) was respectively found in Pingyi,Qingzhou and Sishui. Conclusions The threatened crowds in KSD endemic area in Shandong province are still in a state of high abnormal electrocardiogram detection,and electrocardiogram is of great value in the evaluation of KSD patients.
