Chemical constituents of the essential oil in above-ground and root of Bupleurum malconense and root of B. chinense were investigated by GC-MS compiled with automated mass spectral deconvolution and identification system (AMDIS) and retention index. The results showd that the components of essential oil in B. malconense have some similarities with the one in B. chinense, and both of them have the higher content of caryophyllene oxide which is an active component of anti-inflammatory and analgesic. These results suggested that as a local substitute, B. malconense has a certain scientific basis of the treatment for cold fever.

Objective To evaluate the effect of off-pump coronary endarterectomy (CE) plus off-pump coronary artery bypass grafting (off-pump CABG) on patients with chronic total occlusion (CTO) combined with diffuse distal atherosclerosis. Methods From October 2006 to August 2009,65 CTO patients with 176 angiographically confirmed vascular stenosis or occlusive lesions, 70 of which were complete occlusion, underwent off-pump CABG. During the operation, diffuse intimal thickening distal to occlusive lesion was found, and blood flow of the bridges was unfavorable.Results Therefore endarterectomy was performed, followed by CABG. The blood flow in the bridges were 2-10 ml/min versus 14-37 ml/min before versus after endarterectomy. Pulsatility index (PI) was 5.1-15.6 versus less than 5 before versus after endarterectomy. Left ventricular ejection fraction was also improved significantly [before operation: (0.47±0.12)%, after operation: (0. 52±0.15)%, t=2.17, P＜0.05]. Peri-operative myocardial infarction occurred in 2 cases, but without significant cardiac homodynamic changes. And 23 patients underwent coronary angiography to evaluate graft patency 3-18 months after operation, all of them had favorable blood flow. Conclusions It is feasible to perform off-pump CABG plus coronary endarterectomy for patients of chronic coronary total occlusion combined with diffuse distal atherosclerosis. This treatment is safe and effective.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P＜0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P＜0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P＜0.01)and the area of microcysts was larger(P＜0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P＜0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.

Objective To observe the therapeutic effect of single lower limb traction plus massage for the lumbosacral tunnel syndrome.Methods The selected 80 candidate patients were divided into the observation group with 38 patients and treatment group with 39 patients. The observation group received single lower limb traction plus massage and the treatment group received pelvic traction plus massage. Both groups therapy last 5 days, The Japanese orthopaedic association scores (JOA) was evaluated for subjective symptoms, signs, functional activity and bladder function score. The therapeutic effect was evaluated.Results The total effective rate (94.7% vs. 82.1%;χ2=12.160,P=0.007) in the observation group was significantly higher than that in the control group. O, The scores of JOA at one week after treatment (20.2 ± 2.0 vs. 18.3 ± 2.8;t=3.419, P<0.01) and two weeks after treatment (24.4 ± 1. 4vs. 22.6 ± 3.0;t=3.359,P<0.01) in the observation group were significantly higher than those in the control group.Conclusions The single lower limb traction plus massage can improve the clinical symptoms of patients with lumbosacral tunnel syndrome, and be superior to the pelvic traction plus massage.

A new kind of curcin (curcin 2), induced by several kinds of stresses from Jatropha curcas leaves, under the control of the 35S CaMV (cauliflower mosaic virus) promoter, was introduced into tobacco genome by Agrobacterium tumefaciens-mediated transformation method. Curcin 2 protein was only detected in the transgenic tobacco plants transformed with the cur2p fragment (coding premature curcin 2 protein), but not in the plants transformed with cur2m fragment (coding mature curcin 2 protein). The transgenic lines expressing curcin 2 showed increased tolerance to tobacco mosaic virus (TMV).

Background The main cause of filtering surgery failure is over proliferation of fibroblasts in filtering channels,leading to excessive fibrosis and scar formation.Researches determined that p38 mitogen-activated protein kinase(MAPK) signaling pathway plays an important role in fibroblast phenotype transition. Objective The present study was to investigate the inhibitory effect of p38 MAPK inhibitor on myofibroblasts transdifferentiation and the extracellular matrix synthesis after filtration surgery in rabbit eyes. Methods Trabeculectomy was performed on 24 eyes of 12 clean New Zealand white rabbits to establish the filtering operative models.The models were randomized into model group,SB203580 group and mitomycin C ( MMC ) group.1 ml SB203580 ( 0.2 g/L) was conjunctively injected at the end of operation in the rabbits of the SB203580 group,and the cotton piece with 0.2 g/L MMC solution was placed on the operative area for 3 minutes intraoperatively in the rabbits of the MMC group.The bleb appearances were examined under the slit lamp microscope,and intraocular pressure(IOP) was measured with Icare tonometer I,3,7,10,14 days after operation.0.2 ml aqueous humor was extracted and the conjunctive tissue at the filtering area was obtained 14 days after operation for the detection of α-smooth muscle actin (α-SMA) and fibronectin protein by ELISA.Expression of ACTA2 mRNA,connective tissue growth factor(CTGF) mRNA and alpha2 chain of type Ⅰ collagen( COL1A2 )mRNA in conjunctive tissue was assayed with fluorescence real-time PCR. Results Vascularization of fibrosis of filtering bleb were obvious in the eyes of the model group,and the bleb was flat and diffuse in the eyes of the SB203580 group and MMC group on 14 days following operation.No significant difference was seen in IOP before trabeculectomy among these three groups( F=0.065,P=0.937 ).IOP was gradually elevated with the increase of time after operation ( F =32.873,P =0.030 ).ELISA assay showed that α-SMA level in conjunctiva was lower in the SB203580 group and MMC group compared with the model group,and that of MMC group was significant lower than the SB203580 group( P＜0.05 ).Fibronectin level in conjunctiva was lower in the SB203580 group and MMC group compared with the model group,and that of MMC group was significant lower than the SB203580 group (P＜0.05).Fluorescence real-time PCR showed that expressions of the ACTA2 mRNA,CTGF mRNA and COL1A2 mRNA were significantly different among the three groups( P＜0.01 ),with the highest expression in model group and the lowest expression in the MMC group ( P ＜ 0.05 ). Conclusions Fibrotic reaction after trabeculectomy can be suppressed by inhibiting p38 MAPK signal pathway.The mechanism of SB203580 is to reduce the synthesis of myofibroblasts transdiffercntiation and extracellular matrix.

Abstract: Objective　To analyze the drug sensitivity and the carrying of carbapenem resistant gene of Acinetobacter baumannii isolated from clinical patients and clinical objects, and analyze the homology of strains to provide support for the control of nosocomial infection. Methods　A total of 38 strains of Acinetobacter baumannii isolated from patients and clinical objects surface were collected from January 2019 to August 2020. The antimicrobial susceptibility was tested by the minimum inhibitory concentration method. In addition, the resistance related genes were detected by polymerase chain reaction method, and homology analysis was performed by enterobacterial repetitive Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR). Results All 34 strains of Acinetobacter baumannii isolated from Clinical patients and 4 strains isolated from clinical objects carried blaOXA-51 and imp resistance genes, neither of them carried blaVIM gene. 32 Acinetobacter baumannii carrying blaOXA-23 gene, 28 strains carrying blaTEM gene, 7 strains carrying blaOXA-58 gene. After cluster analysis, 38 Acinetobacter baumannii isolates were classified into 7 genotypes (expressed A, B, C, D, E, F, G), and cluster E and cluster G were the main clusters, containing 12 strains (12/38, 31.6%) and 18 strains (18/38, 47.4%), respectively, as the main prevalent clonal strains. Conclusions　Acinetobacter baumannii isolated from different sources have the significant differences in drug resistance and carry different resistance genes. There is no direct correlation between patients and environmental isolates of Acinetobacter baumannii belonging to different clonal strains. Also, there aren’t significant correlation between clinical patients infected with Acinetobacter baumannii.

Objective To study the therapeutic efficacy of Chinese botulinum toxin type A (CBTX- A) in masticatory spasm patients.Methods 16 patients with masticatory spasm were treated with CBTX-A local injection.12 patients showed jaw clench with masseter and temporalis affected (type Ⅰ).Four showed jaw clench and deviation to one side with pterygoid muscle affected unilaterally or bilaterally (type Ⅱ).All patients showed paroxysmal clenched jaw with difficulty in opening their mouths.There were no other clinical manifestations.CT and MRI did not reveal any intracerebral abnormalities.The efficacy and adverse effects were observed.Results CBTX-A were injected into 16 patients,resulting in a significant improvement of symptoms in 13 cases (4 cases of unilateral type Ⅰ,7 of 8 cases bilateral type Ⅰ,2 of 4 type Ⅱ).The spasms ceased within 3-10 days after the injection,and the effects lasted for 8-26 weeks.Four patients were observed to have slight masseter weakness after the injections,which recovered within a few weeks.The benefit persisted after identical repeated injection.Conclusion CBTX-A injection is an effective and safe treatment for masticatory spasm.

Objective To discuss the pulmonary function change in infants with human bocavirus (HBoV) pneumonia or mycoplasma pneumonia (MP) and its clinical signiifcance. Methods One hundred and forty infants under 3 years old who were admitted due to pulmonary infection were recruited from January, 2013 to October, 2013. Among them, HBoV-DNA was detected in 64 cases, and MP-DNA was detected in 76 cases. Thirty eight normal age-matched infants were selected as controls. The shape of tidal breathing lfow-volume loops (TBFVLs) and change of every index were measured with a Pulmonary Testing System (Jaeger MasterScope). Results The ratio of time to peak tidal expiratory lfow (PTEF) to total expiratory time (TPTEF/TE), the ratio of VPTEF to expiratory volume (VPTEF/VE), tidal expiratory lfow at 25%of the remaining tidal volume (TEF25%) and the ratio of TEF25%to PTEF (25/PF) were signiifcantly decreased in infants with HBoV and MP infection as compared with healthy infants (P<0.05). However, there was no signiifcant difference of the above indices between infants with HBoV and MP infection (P>0.05). The shape of TBFVLs in infants with HBoV and MP pneumonia was changed and characterized by left-shifted PTEF and trough-like concave in descending limb. The PTEF was decreased in infants with pulmonary infection. Conclusions HBoV or MP infection results in impaired pulmonary function with manifestations of obstruction in small airway. The shape of TBFVLs in infants with HBoV and MP pneumonia is characterized by left-shifted PTEF and trough-like concave in descending limb.
