Objective To evaluate the clinical effect of acupotomy therapy combined with acupuncture based on distal points selection for lumbar intervertebral disc protrusion ( LIDP) . Methods Sixty-eight LIDP patients were randomly divided into treatment group (N=33) and control group(N=35). The treatment group were given acupotomy therapy on the proximal positive response points in the lumbosacral region for relaxing the tendons,and acupuncture therapy based on distal points selection of Shugu, the Shu-stream point of the foot Taiyang bladder meridian, Zulinqi and Weizhong, the shu-stream point and the blood xi-cleft point of the foot Shaoyang gallbladder meridian respectively, twice a week, 2 weeks constituting one course of treatment. The control group was given conventional electroacupuncture therapy on Huatuo clip points, Dachangshu point, bilateral Shenshu points, Yinmen point, bilateral Zibian points and bilateral Yanglingquan points, and together with TDP radiation therapy, 5 times a week, 2 weeks constituting one course of treatment. The two groups received follow-up for one month. The low back pain scores of Japanese orthopaedic society ( JOA) and visual analog scores ( VAS) of pain were used for the evaluation of therapeutic effect after the treatment. Results ( 1) After treatment, the JOA scores were increased and VAS scores were decreased in both groups compared with those before treatment ( P< 0.05) , and the increase of JOA scores and the decrease of VAS in the treatment group were superior to those in the control group ( P< 0.05) . There was statistically significant difference of VAS scores between the two groups ( P < 0.05) during the follow-up period. ( 2) The total effective rate was 87.9%in the treatment group, and was 77.1%in the control group, the difference being significant (P<0.05) . Conclusion The acupotomy therapy combined with acupuncture based on distal points selection is effective and safe for lumbar intervertebral disc protrusion, which has the advantages of reliable long-term effect and low recurrence rate, showing good prospects for extensive clinical application.

OBJECTIVE:To provide reference for promoting the further implementation of national essential medicine system and rational use of drugs in community health service center. METHODS:Outpatients’information in Changqiao Street Communi-ty Health Service Center from Sept. 2,2009 to Nov. 25,2014 was collected to statistically analyze the drug variety,the number of prescriptions,the consumption sum and the DDDs before and after the implementation of essential medicine system and after the supplement of non essential medicines. RESULTS:Essential medicines occupied the main position of drug utilization in each stage, with substantial growth in respects of consumption sum and number of prescriptions;the sum of Chinese patent drugs and essential cardiovascular drugs occupied more than 50% of the total consumption sum and number of prescriptions,with higher growth rate;essential medicines occupied the top 10 in respects of consumption sum and DDDs,among which most were the drug varieties in“Shanghai supplement essential drugs in community health service center”(2010 Edition),with some overlap the varieties in“Na-tional Essential Medicine System”(2012 Edition);cardio-cerebrovascular drugs occupied the dominant position;the growth rates of cefotiam and atorvastatin took up the top 2 ranking in the list of consumption sum,while the growth rates of calcium carbonate D3 and irbesartan and hydrochlorothiazide took up the top 2 ranking in the list of DDDs. CONCLUSIONS:Essential medicine cata-log covers the common drugs in the community health service center,in which the rational use of Chinese patent drugs and antibac-terial deserves needs to be noticed. The clinical rational use of the essential medicines should be strengthened,the essential medi-cine catalog should be adjusted and non essential medicines should be supplied when necessary in order to truly meet the needs of patients and optimize the allocation of medical resources.

Objective To evaluate the potential use of a probe melting analysis (PMA) assay in detecting the embB mutations which confer resistance against ethambutol in Mycobacterium tuberculosis. Methods The analysis sensitivity and specificity of PMA were investigated by detecting a serially diluted H37 Rv DNA and a reference panel from National Institute for the Control of Pharmaceutical and Biological Product. Six hundred and thirteen sputum samples were collected from the Xiamen Center for Disease Control and Prevention, Xiamen First Hospital and Center for Zhangzhou Disease Control and Prevention from September 2009 to April 2010. The PMA assay was then evaluated by detecting 613 clinical isolates and the results were compared with the sequencing results. Results The PMA assay could specifically detect Mycobacterium tuberculosis and had a limit of detection of 3 copies per reaction. The assay results with 613 clinical isolates showed that PMA gave a 100% concordance with sequencing in the 583 qualified samples, among which 34 were mutations at embB 306,23 at embB 378-380, 3 at embB 406 and 3 at embB 497. Conclusions PMA assay is a sensitive and specific method enabling efficient detection of common embB mutations causing ethambutol-resistance. The rapidness of this method together with its reliability would facilitate its use in routine testing.

Objective To study the effects of the rehabilitation robot-assisted task-oriented training on the hand function in patients after stroke. Methods From June, 2015 to September, 2016, 35 inpatients suffering from stroke were randomly allocated to control group (n=17) and trial group (n=18). Based on the routine rehabilitation, the trial group accepted robot-assisted task-oriented training, while the control group accepted therapist-assisted task-oriented training, for two weeks. They were measured the active range of motion (AROM) of fingers, assessed with fingers motor of Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) invovled with hands before and after train-ing. Results The inpatients dropped three in the control group, two in the trial group. AROM of extension and flexion of all the fingers, the AROM of extension and total of three fingers of thumb, index and middle, and the total AROM of each finger improved in the trial group af-ter training (t>2.937, P<0.05), while the AROM of extension and flexion of all the fingers, AROM of extension, flexion and total of the fin-gers of thumb, index and middle, total AROM of the fingers of thumb, index and little improved in the control group after training (t>2.528, P<0.05);the AROM of extension and total of the fingers of thumb, index and middle, and the total AROM of fingers of thumb and index im-proved more in the trial group than in the control group (t>2.535, P<0.05). The scores of mass flexion, mass extension, opposition, cylinder grip, spherical grip and total score of FMA improved in the trial group after training (Z>2.000, P<0.05), while the scores of mass extension, opposition and the total score of FMA improved in the control group after training (Z>2.000, P<0.05). There was no significant difference between the two groups on the items and total scores after training (P>0.05). The scores of feeding, dressing, toilet transfers, bathing, groom-ing of MBI and the total score of them improved in the trial group after training (Z>2.041, P<0.05), while the total score of MBI improved in the control group after training (Z=-2.527, P<0.05). There was no significant difference between the two groups in the items and total scores after training (P>0.05). Conclusion The rehabilitation robot-assisted task-oriented training can improve AROM of hemiplegic fingers and grip function.

Aim To investigate the impact of CYP3 A5 genetic polymorphism on modified releasing tacrolimus pharmacokinetics in Chinese stable renal transplant re-cipients. Methods Pharmacokinetics of once daily-ta-crolimus( tac-q. d. ) and twice daily-tacrolimus( tac-b. i. d. ) were determined by CLIA, CYP3A5 genotype was measured by PCR-RFLP. Each 10 patients receiv-ing tac-q. d. and tac-b. i. d. respectively were en-rolled, and each 5 patients receiving tac-q. d. were matched to poor metabolizer ( PM ) and extensive me-tabolizer ( EM ) group respectively according to CYP3A5 genotypes. Results AUC0~24 h for tac-q. d. was 1. 78 folds higher than AUC0~12 h for tac-b. i. d. , and dose-adjusted C0 was 40% lower for tac-q. d. than for tac-b. i. d. There were no significant differences for other parameters between the two groups; Cmax, AUC0~24 h and C0 were 1. 75, 1. 96 and 2. 49 folds higher for PM than for EM, and dose-adjusted Cmax, AUC0~24 h and C0 were 1. 80, 2. 34 and 2. 64 folds higher for PM than for EM. There were good correla-tions between AUC0~24 h and C0 for tac-q. d. Conclu-sion Conversion from tac-b. i. d. to tac-q. d. results in requirement of increased tacrolimus dose and detec-tion of CYP3A5 genotype, which is necessary for ensu-ring C0 in the range of therapeutic window.

Objective:To correlate acute ischemic stroke with leukoaraiosis with intracranial and extracranial artery stenosis.Methods:A total of 300 patients with acute ischemic stroke admitted to Shaoxing Second Hospital from January to December 2017 were included in this study. All patients underwent magnetic resonance (MRI) examination. According to the examination results, these patients were divided into control (acute ischemic stroke, n = 100) and acute ischemic stroke with leukoaraiosis, n = 200). Carotid artery plaque size and blood sugar level were recorded in each group. Intracranial and extracranial large artery stenosis rates were compared between the two groups. Severity of leukoaraiosis was correlated with intracranial and extracranial artery stenosis. Results:The percentage of patients developing hypertension in the observation group was significantly higher than that in the control group [66.0% (132/200) vs. 44.0% (44/100), χ2 = 13.31, P < 0.01]. The incidence of coronary heart disease in the observation group was significantly higher than that in the control group [49.0% (98/200) vs. 31.0% (31/100), χ2 = 8.81, P < 0.01]. The incidence of carotid artery plaque in the observation group was significantly higher than that in the control group [49.5% (99/200) vs. 34.0% (34/100), χ2 = 6.49, P = 0.01]. The incidence of carotid artery stenosis in the observation group was significantly higher than that in the control group [23.5% (47/200) vs. 12.0% (12/100), χ2 = 5.58, P = 0.01]. There was no significant difference in the incidence of anterior cerebral artery stenosis between observation and control groups [5.5% (11/200) vs. 4.0% (4/100), χ2 = 0.32, P = 0.57]. The size of carotid artery plaque in the observation group was significantly larger than that in the control group [(1.86 ± 0.42) cm vs. (1.39 ± 0.27) cm, t = 10.18, P < 0.01]. The incidence of intracranial and extracranial artery stenosis in the observation group was significantly higher than that in the control group [41.0% (82/200) vs. 24.0% (24/100), χ2 = 8.43, P < 0.01]. The severity of leukoaraiosis was positively correlated with the degree of intracranial and extracranial artery stenosis ( r = 0.79, P < 0.01). Conclusion:Patients with acute ischemic stroke with leukoaraiosis have a high intracranial and extracranial artery stenosis and the severity of leukoaraiosis is positively correlated with intracranial and extracranial artery stenosis.

The Lianhua Qingwen (LHQW) capsule is a popular traditional Chinese medicine for the treatment of viral respiratory diseases.In particular,it has been recently prescribed to treat infections caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).However,due to its complex composi-tion,little attention has been directed toward the analysis of chemical constituents present in the LHQW capsule.This study presents a reliable and comprehensive approach to characterizing the chemical constituents present in LHQW by high-performance liquid chromatography-Q Exactive-Orbitrap mass spectrometry (HPLC-Q Exactive-Orbitrap-MS) coupled with gas chromatography-mass spectrometry(GC-MS).An automated library alignment method with a high mass accuracy (within 5 ppm) was used for the rapid identification of compounds.A total of 104 compounds,consisting of alkaloids,flavonoids,phenols,phenolic acids,phenylpropanoids,quinones,terpenoids,and other phytochemicals,were suc-cessfully characterized.In addition,the fragmentation pathways and characteristic fragments of some representative compounds were elucidated.GC-MS analysis was conducted to characterize the volatile compounds present in LHQW.In total,17 compounds were putatively characterized by comparing the acquired data with that from the NIST library.The major constituent was menthol,and all the other compounds were terpenoids.This is the first comprehensive report on the identification of the major chemical constituents present in the LHQW capsule by HPLC-Q Exactive-Orbitrap-MS,coupled with GC-MS,and the results of this study can be used for the quality control and standardization of LHQW capsules.

Background: and Purpose Intracranial vertebrobasilar atherosclerotic stenosis (IVBAS) is a major cause of posterior circulation stroke. Some patients suffer from stroke recurrence despite receiving medical treatment. This study aimed to determine the prognostic value of a new score for the posterior communicating artery and the P1 segment of the posterior cerebral artery (PCoA-P1) for predicting stroke recurrence in IVBAS. Methods: We retrospectively enrolled patients with severe IVBAS (70%–99%). According to the number of stroke recurrences, patients were divided into no-recurrence, single-recurrence, and multiple-recurrences groups. We developed a new 5-point grading scale, with the PCoA-P1 score ranging from 0 to 4 based on magnetic resonance angiography, in which primary collaterals were dichotomized into good (2–4 points) and poor (0 or 1 point). Stroke recurrences after the index stroke were recorded. Patients who did not experience stroke recurrence were compared with those who experienced single or multiple stroke recurrences. Results: From January 2012 to December 2019, 176 patients were enrolled, of which 116 (65.9%) had no stroke recurrence, 35 (19.9%) had a single stroke recurrence, and 25 (14.2%) had multiple stroke recurrences. Patients with single stroke recurrence (odds ratio [OR]= 4.134, 95% confidence interval [CI]=1.822–9.380, p=0.001) and multiple stroke recurrences (OR=6.894, 95% CI=2.489–19.092, p<0.001) were more likely to have poor primary collaterals than those with no stroke recurrence. Conclusions The new PCoA-P1 score appears to provide improve predictions of stroke recurrence in patients with IVBAS.

In order to realize brain-computer interface (BCI), optimal features of single trail motor imagery electroencephalogram (EEG) were extracted and classified. Mu rhythm of EEG was obtained by preprocessing, and the features were optimized by spatial filtering, which are estimated from a set of data by method of common spatial pattern. Classification decision can be made by Fisher criterion, and classification performance can be evaluated by cross validation and receiver operating characteristic (ROC) curve. Optimal feature dimension determination projected by spatial filter was discussed deeply in cross-validation way. The experimental results show that the high discriminate accuracy can be guaranteed, meanwhile the program running speed is improved. Motor imagery intention classification based on optimized EEG feature provides difference of states and simplifies the recognition processing, which offers a new method for the research of intention recognition.
