ABSTRACT

OBJECTIVE@#To observe the effect of acupotomy on the morphology and ultrastructure of rectus femoris muscle in rabbits with knee osteoarthritis and to reveal the possible therapeutic mechanism involved in the effect of acupotomology on the treatment of knee osteoarthritis(KOA).@*METHODS@#Twenty-four male New Zealand rabbits aged 6 months and weighed (2.0±0.5) kg were randomly divided into blank group, model group and acupotomy group, 8 rabbits in each group. KOA model was established by modified Videman method with left hind limb extended plaster immobility for 6 weeks. In acupotomy group, the transfascial focal points of quadriceps femoris muscle were released by acupotomy under the guidance of Jingjin theory for 4 times and once a week, and the treatment points include Hedingci, Binwaixia, Binneixia. Blank group and model group were fed normally without intervention. One week after the end of the intervention, the pennation angle(PA), muscle thickness(MT), cross-sectional area(CSA) and strain ratio(SR) of rectus femoris were measured by ultrasound. HE staining was used to observe the changes of the tissue morphology, the number of muscle fibers and the average area of muscle fibers. The myofibril of rectus femoris, sarcomere and myofilament were observed by transmission electron microscope.@*RESULTS@#The PA of rectus femoris muscle in the blank group was (9.05±0.21)°. The MT was(1.09±0.09) cm and the CSA was(1.30±0.01) cm2. The PA of rectus femoris muscle in the model group was (3.06±0.15)°. The MT was (0.71±0.02) cm and the CSA was(0.77±0.02) cm2. The PA of rectus femoris muscle in the acupotomy group was (6.94±0.28)°. The MT was (0.80±0.05) cm and the CSA was(0.94±0.03) cm2. The muscle PA, MT and CSA of rectus femoris in the model group were significantly smaller than those in the blank group (P<0.05). Those in acupotomy group were significantly increased compared with those in model group (P<0.05). The SR of rectus femoris muscle was 1.19±0.02 in the blank group, 3.50±0.05 in the model group and 1.99±0.07 in the acupotomy group. The elastic SR of the model group was significantly higher than that of the blank group (P<0.05). These in acupotomy group was significantly lower than that in model group(P<0.05). The results of HE staining showed:in blank group, the fascicles of rectus femoris were arranged neatly, the number of beam of muscle fibers within the fixed visual field was 94.38±3.50 and the average CSA was(0.75±0.22) mm2. In model group, the fascicles of rectus femoris with different sizes were disorganized with a small amount of inflammatory cell infiltration, the number of beam of muscle fibers within the fixed visual field was 196.63±2.62 and the average CSA was(0.26±0.03) mm2. Compared to the blank group, a significant increase in the number of muscle fibers in the fixed field in the model group (P<0.05) and the average CSA decreased significantly(P<0.05). In acupotomy group, the rectus femoris fascicles in the acupotomy group tended to be arranged in a more orderly manner, with the inflammatory cells decreased, the number of beam of muscle fibers within the fixed visual field was 132.88±4.61 and the average CSA was(0.70±0.07) mm2. Compared to the model group, a significant decrease in the number of muscle fibers in the fixed field in the model group(P<0.05) and the average CSA increased significantly(P<0.05). The results of transmission electron microscope showed:compared with the blank group, the overall arrangement of the myofibrils of the rectus femoris in the model group was less structured. There was fracture between the muscle fibers and the sarcomere, the myofilaments were disordered, and the fracture of the Z line was discontinuous. Compared with the model group, the myofibrillar texture of rectus femoris in acupotomy group was clearer, and the Z line was more continuous.@*CONCLUSION@#Based on the jingjin theory, the release of quadriceps femoris by acupotomy can effectively improve the morphology and structure of rectus femoris, and promote the repair and reconstruction of chronic skeletal muscle injury in rabbits with KOA, which may be one of the mechanisms of acupotomy in the treatment of KOA.

Randomized controlled trials of Chinese patent medicines for insomnia were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library databases from the time of database establishment to October 2020. The quality of the included RCTs was evaluated according to the Cochrane bias risk standard, and the data was analyzed by RevMan 5.3 and Stata/MP 15.1. A total of 11 kinds of Chinese patent medicines in 27 RCTs were included. According to Meta-analysis, in term of the effective rate, Tianmeng Liquid, Zaoren Anshen Capsules, Shumian Capsules, Shensong Yangxin Capsules, Shenqi Wuweizi Tablets, Shugan Jieyu Capsules, Anshen Bunao Liquid and Qiye Anshen Tablets combined with nonbenzodiazepine drugs(NBZDs) were superior to NBZDs alone. In term of the improvement of Pittsburg sleeping quality index(PSQI) score, Tianmeng Liquid, Shumian Capsules, Shensong Yangxin Capsules, Bailemian Capsules, Shenqi Wuweizi Tablets, Shugan Jieyu Capsules, Yangxue Qingnao Granules and Yindan Xinnaotong Capsules combined with NBZDs were superior to NBZDs alone. In terms of the safety, Shumian Capsules, Shensong Yangxin Capsules, Shenqi Wuweizi Tablets and Qiye Anshen Tablets combined with NBZDs were superior to NBZDs alone. In terms of the avoidance of dizziness and headache, Qiye Anshen Tablets combined with NBZDs were superior to NBZDs alone. The results of Network Meta-analysis indicated that in term of the effective rate, top three optimal medication regimens were NBZDs combined with Shugan Jieyu Capsules, combined with Zaoren Anshen Capsules and combined with Shensong Yangxin Capsules in the order from high to low. With the respect of improvement of PSQI score, top three optimal medication regimens were NBZDs combined with Yangxue Qingnao Granules, combined with Tianmeng Liquid and combined with Yindan Xinnaotong Capsules in the order from high to low. In terms of the safety, top three optimal medication regimens were NBZDs combined with Qiye Anshen Tablets, combined with Shensong Yangxin Capsules and combined with Shenqi Wuweizi Tablets in the order from high to low. In terms of the avoidance of dizziness and headache, top three optimal medication regimens were NBZDs combined with Qiye Anshen Tablets, combined with Zaoren Anshen Capsules and combined with Shumian Capsules in the order from high to low. In terms of the avoidance of fatigue, top three optimal medication regimens were NBZDs combined with Shensong Yangxin Capsules, combined with Shumian Capsules and combined with Qiye Anshen Tablets in the order from high to low. In conclusion, Chinese patent medicines combined with NBZDs can effectively alleviate the symptoms of insomnia with a high safety. However, the conclusion of this study needs to be verified by more high-quality studies because of the low methodological quality of the included studies.

ABSTRACT

Although the guiding principles for molecular identification of traditional Chinese medicines (TCM) using DNA barcoding have been recorded in the Chinese Pharmacopoeia, there is still a lack of systematic research on its application to commercial TCM decoctions. In this study, a total of 212 commercial TCM decoctions derived from different medicinal parts such as root and rhizome, fruit and seed, herb, flower, leaf, cortex, and caulis were collected to verify applicability and accuracy of the method. DNA barcodes were successfully obtained from 75.9% (161/212) of the samples, while other samples failed to be amplified due to genomic DNA degradation. Among the 161 samples, 85.7% of them were identified as recorded species in the Chinese Pharmacopoeia (2020 edition). In addition, 14 samples could be identified as species recorded in the Chinese Pharmacopoeia and their closely related species in the same genus. Morphological identification for the unconfirmed samples showed that eight were genuine species and three were adulterants, while the other three were unidentifiable due to lack of morphological characteristics. Furthermore, the DNA barcodes of seven samples accurately mapped to the sequences of adulterants. Remarkably, counterfeit products were detected in two samples. These results demonstrate that DNA barcoding is suitable for the identification of commercial TCM decoctions. The method can effectively detect adulterants and is appropriate for use throughout the industrial chain of TCM production and distribution, and by the supervisory agencies as well.

ABSTRACT

OBJECTIVE@#To explore the ultrasonic anatomical characteristics and needle-knife insertion approach of common tendon lesions in knee osteoarthritis (KOA), so as to provide the references for accurate release of KOA by needle- knife along tendon lesions based on meridian sinew theory.@*METHODS@#Sixty patients with one-knee KOA were selected. High-frequency musculoskeletal ultrasound was used to collect sonograms at the anatomical positions of "Hedingci" "Binwaixia" "Binneixia" and "Yinlingshang". The anatomic levels were marked on the sonograms. The anatomic levels and sonographic features of lesions were compared and analyzed, and the relevant data of needle-knife simulation approach was measured.@*RESULTS@#The "Hedingci" lesions were mainly located at the attachment of quadriceps tendon to patella and suprapatellar bursa. The "Binwaixia" and "Binneixia" lesions were mainly located at the attachment of retinaculum patellae laterale and retinaculum patellae mediale to patella and infrapatellar fat pad. The "Yinlingshang" lesions were mainly located at the attachment of goose foot tendon to medial tibial condyle and bursa of goose foot. With "Hedingci" as an example, when the needle-knife entry point was 1 cm above the patella, the attachment of quadriceps tendon to patella was released, and the average depth of needle-knife was (3.60±0.10) cm, and the needle body was perpendicular to the skin. The average depth of needle-knife for releasing suprapatellar bursa was (2.35±0.17) cm, and the needle body was 45° towards head.@*CONCLUSION@#The musculoskeletal ultrasound could clearly show the local detailed anatomical level, ultrasonic characteristics and anatomical level of common tendon lesions of KOA, and could improve the accuracy of needle-knife along tendon lesions with non-direct vision, which has important reference value for needle-knife medical standardization and standardized operation.

ABSTRACT

Objective:To explore the mechanism of modified Guipitang in the treatment of Yin-Fire insomnia with anxiety with the help of network pharmacological analysis technology. Method:Traditional Chinese Medicine Systems Pharmacology (TCMSP) was used to screen the main components and target genes of modified Guipitang. GeneCards and Online Mendelian Inheritance in Man (OMIM) were used to establish the target gene sets of insomnia and anxiety. STRING 11.0 software was used to analyze the interaction between the overlapping genes, and Cytoscape_3.6.1 software analysis and Matthews correlation coefficient (MCC) algorithm were used to screen the core genes. Based on the results of network analysis, 48 SD female rats were randomly divided into blank control group, model group, eszopiclone tablets group (0.2 mg·kg-1·d-1), modified Guipitang low,medium,and high-dose groups (0.31,1.25,5 g·kg-1·d-1). The model of insomnia with anxiety was established by intraperitoneal injection of Para-chlorophenylalanine (PCPA) and these rats were treated with corresponding drugs for 7 days. Then the frequency, time and distance of the activities were observed in the experiment of autonomic activity. Real-time quantitative polymerase chain reaction (PCR) was used to detect the mRNA expressions of proactivated protein kinase 8 (MAPK8), RAC-alpha serine/threonine protein kinase (Akt1), mitogen-activated protein kinase 3 (MAPK3) and interleukin-6 (IL-6) in rat hippocampus. Result:A total of 228 active compounds were screened from TCMSP database and 181 intersecting genes of diseases and drugs were obtained by comparing with GeneCards and OMIM comprehensive database. 9 core genes, including MAPK3, MAPK8, Akt1 and IL-6 were identified by STRING software and MCC algorithm. Animal experiments showed that the number of activity times, time and distance of modified Guipitang in high and medium dose groups were significantly lower than those in the model group. The high and middle dose groups of modified Guipitang could significantly inhibit the mRNA expression of MAPK3, MAPK8, Akt1 and IL-6 in hippocampus(P<0.01), while the low dose group had no significant effect. Conclusion:The mechanism of modified Guipitang in treating Yin-fire insomnia with anxiety may be related to the regulation of MAPK3, MAPK8, Akt1 and IL-6 genes.

ABSTRACT

Zuoguiwan is a classic prescription for replenishing vital essence, tonifying kidney-Yin and nourishing the bone marrow. Zuoguiwan is one of the effective prescriptions for the prevention and treatment of osteoporosis (OP), which reflects the thought of Reinforcing Yang from Yin. The OP animal model simulates the pathological state and pathogenesis of OP in human, which is an important means to research the pathogenesis of OP and verify the effect of drugs. In this paper, two kinds of animal models and characteristics of Zuoguiwan in the prevention and treatment of osteoporosis were discussed in details. They are the primary osteoporosis animal models, including ovariectomized animal models and spontaneous elderly osteoporosis animal models, and the secondary osteoporosis models, including glucocorticoid-induced animal models, cyclophosphamide-induced animal models and subtotal nephrectomy animal models. The evaluation methods of Zuoguiwan in preventing and treating OP, including bone absorption markers and bone formation markers analyzed by enzyme-linked immunosorbent assay (ELISA), bone mineral density detected with dual-energy X-ray, the number of trabeculae, trabecular segregation, trabecular thickness, bone volume/tissue volume ratio and bone surface/volume ratio analyzed using micro-CT, bone pathological morphology observed by hematoxylin-eosin staining, bone biomechanical properties, such as the maximum load force based on biomechanical test. In order to provide scientific reference for the basic and clinical research of Zuoguiwan, the OP animal models and the pharmacodynamic effect of Zuoguiwan are evaluated comprehensively with five different and objective evaluation methods. However, the animal model of OP needs to be further optimized to highlight the pathogenesis and syndrome characteristics of Zuoguiwan in the treatment of OP.

ABSTRACT

Ginseng has effects in reinforcing vital energy,invigorating health effectively and relieving fatigue symptoms,and ginsenoside( GS) is the main component of its anti-fatigue effect. Totally 17 active components and 92 drug targets of ginseng compounds were screened from Traditional Chinese Medicine Systems Pharmacology; and 78 intersecting genes of diseases and drug targets were obtained based on R Language Technology. The protein-protein interaction( PPI) network was constructed by STRING 11. 0 software,and Matthews Correlation Coefficient( MCC) algorithm was used to screen core target genes. Gene ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were used to analyze the major genes and their roles in regulatory networks. The results indicated that ginseng could regulate the core target genes,including AKT serine/threonine kinase( AKT1),interleukin-1β,Toll-like receptor binding molecule 1( ICAM1),mitogen-activated protein kinase 8( MAPK8),AP-1 transcription factor subunit( JUN),transducer and activator of transcription 1( STAT1) and prostaglandin peroxidase synthase 2( PTGS2). It could participate in the functions of cytokine receptor binding,cell adhesion molecule binding and tumor necrosis factor receptor superfamily binding,and also regulate the signal pathways of tumor necrosis factor,interleukin 17 and c-type lectin receptor,so as to exert an anti-fatigue effect. Based on the results of network analysis,32 four-week-old male SPFACR mice were randomly divided into control group,low-dose ginsenoside group,middle-dose ginsenoside group and high-dose ginsenoside group. The corresponding drugs were administrated for 3 weeks. The results showed that GS could significantly up-regulate the expressions of STAT1 and AKT1( P<0. 01,P<0. 05),and downregulate the expressions of PTGS2 and JUN( P<0. 01). However,there was no significant effect on MAPK8,IL-1β and ICAM1. Ginseng's anti-fatigue regulation network was constructed through network pharmacology,and the results were verified by experiments,in order to reveal the anti-fatigue mechanism of ginseng and provide scientific basis for its clinical application.

ABSTRACT

The aim of this study is to quantify the 146S antigen in foot-and-mouth disease virus (FMDV) inactivated vaccine by size-exclusion chromatography (SEC). The analysis was performed on a TSKgel G4000SWXL column (7.8 mm×30 cm), with a pH 7.2 buffer salt system as the mobile phase. The flow rate was 0.6 mL/min, the injection volume was 100 μL and the detection wavelength was 259 nm. The calibration curve was established by using purified inactivated FMDV (serotype O) 146S antigen; 3 batches of vaccine formulated by inactivated antigen solution were tested to verify the accuracy, reproducibility, specificity and tolerability of the method. At last 16 batches of vaccine were determined by the SEC method. Results showed a good linearity between peak area and concentration of 146S antigen in the range between 0.56 and 67.42 μg/mL (R2=0.996, n=10), and the average recovery rate of 146S antigen in the 3 batches of vaccine formulated in lab were 93.6% (RSD=2.7%, n=3), 102.3% (RSD=2.6%, n=3), and 95.5% (RSD=5.1%, n=3). The method was proved accurate and reliable with good reproducibility (RSD=0.5%, n=6), and applied to determine 16 batches of the commercial FMDV vaccine. According to the above results, the SEC method is high effective for 146S antigen quantify in the inactivated FMDV vaccine and would provide strong support for the vaccine quality control.

ABSTRACT

Objective To compare the effects of oral use of Compound Danshen Dripping Pills and Mecobalamin Tablets on hemorheology and nerve conduction velocity of diabetic peripheral neuropathy patients. Methods A total of 70 diabetic peripheral neuropathy patients were randomized into treatment group and control group, 35 cases in each group. Both groups were given fundamental treatment for controlling blood glucose, blood lipids and blood pressure, and additionally the treatment group was treated with Compound Danshen Dripping Pills orally and the control group was treated with Mecobalamin Tablets orally. The treatment for the two groups lasted 3 continuous months. The changes of hemorheology and nerve conduction velocity of the two groups were observed before and after treatment. Results After treatment, indexes of hemorheology and nerve conduction velocity of the two groups were much improved(P<0.05 compared with those before treatment). The improvement of hemorheology indexes in the treatment group was superior to that in the control group (P < 0.05), but the difference of improvement of nerve conduction velocity was insignificant between the two groups (P > 0.05). Conclusion The effects of oral use of Compound Danshen Dripping Pills on the nerve conduction velocity of diabetic peripheral neuropathy patients are similar to those of Mecobalamin Tablets, but the pills have better effects on improving hemorheology than the tablets. The results indicated that Compound Danshen Dripping Pills are effective on improving blood flow and nerve conduction velocity of the limbs of the patients.

ABSTRACT

Objective: To investigate the essential biochemical indices like 1 -hydroxylase and hypocalcaemia in the rats with severe acute pancreatitis and explore the correlation between them. Methods: A total of 120 SPF grade Wistar male rats which were in similar physiological status were selected and randomly divided into two groups: sham group (SO group) and severe acute pancreatitis group (SAP group). Then they were divided into 1 h, 3 h, 6 h, and 12 h subgroups according to the killing time. The severe acute pancreatitis model was established by retrograde injection of 5% sodium taurocholate. Serum calcium, serum creatinine, serum urea nitrogen and serum amylase were measured at different time. Serum 1, 25 dihydroxy vitamin D3 level was determined by enzyme linked immunosorbentassay. The expression of 1-hydroxylase protein in the kidney tissue was determined with Western blotting and immunohistochemistry to observe its location. The pathologic features of the kidney tissue section was observed under light microscope and submicroscopic structure of the proximal convoluted tubule epithelial cell was observed under transmission electron microscope. Results: Compared with the SO group, rats in the SAP group showed continuous pathological injury as time went by. There was significant increase in serum creatinine, serum urea nitrogen and serum amylase in SAP group compared with the SO group 1, 3, 6, 12 hours after the operation (P<0.05). There was significant decrease in serum calcium and 1, 25 dihydroxy vitamin D3 3, 6, 12 hours after the operation (P<0.05).

ABSTRACT

Ligustrazine, one of the major effective components of the Chinese traditional medicinal herb Ligusticum Chuanxiong Hort, has been reported plenty of biological activities, such as protect cardiovascular and cerebrovascular, neuroprotection and anti-tumor, et al. Because of its remarkable effects, studies on structural modification of ligustrazine have attracted much attention. Ligustrazine synthetic derivatives reported in recent decades are mainly derived from four primary intermediates (TMP-COOH, TMP-OH, TMP-NH2, HO-TMP-OH). To explore the neuroprotection activitiy of ligustrazine intermediates, six ligustrazine intermediates (2, 5, 8, 11, 12, 13) were synthesized and their protective effects against CoCl2-induced neurotoxicity in differentiated PC12 cells were studied. The target compounds were prepared via different chemical methods, including oxidation, substitution, esterification and amidation without changing the structure nucleus of ligustrazine. Compared with TMP (EC50 = 56.03 micromol x L(-1)), four compounds (2, 5, 12 and 13) exhibited higher activity (EC50 < 50 micromol x L(-1)) respectively, of which, compound 2 displayed the highest protective effect against the damaged PC12 cells (EC50 = 32.86 micromol x L(-1)), but target compounds 8 and 11 appeared lower activity (EC50 > 70 micromol x L(-1)). By structure-activity relationships analysis, the introduction of carboxyl, amino to the side chain of ligustrazine and appropriately increase the proportion of ligustrazine may contribute to enhance its neuroprotective activity, which provides a reference for the design, synthesis and activity screening of relevant series of ligustrazine derivatives in the future.

ABSTRACT

Objective To investigate colonization status and risk factors of multidrug-resistant organisms (MDROs)in a surgical intensive care unit (SICU),and provide a basis for active clinical screening of MDROs. Methods From June 1,2013 to August 31,2013,patients who admitted to SICU≥24 hours were performed active screening,the colnization status of methicillin-resistant Staphylococcus aureus (MRSA)and extended-spectrumβ-lactamase-producing Escherichiacoli/Klebsiellapneumoniae (ESBL-E.coli/Kp)among patients were detected,re-lated risk factors were analyzed. Results When patients who admitted to SICU≤48 hours,the detection rate of MRSA and ESBL-E.coli/Kp was 1 1 .00% and 73 .00% respectively;when admitted to SICU>7 days,the increased detection rate of MRSA and ESBL-E.coli/Kp was 16.67% and 44.44% respectively. Patients stayed in hospital >7 days before admit-ting to SICU (OR95% CI:4.48 [1 .21-16.65 ])was an independent risk factor of carrying MRSA when admitting to SICU,APACHEⅡscore ≥16 (OR95% CI:6.36[1.47-27.54])was an independent risk factor of carrying MRSA 48 hours after admitting to SICU. Conclusion When patients admitted to SICU,the carrying rate of MDROs is high,isola-tion rate rises with prolonged length of SICU stay. Hospitals should carry out MDRO colonization screening proj ect among patients and implement effective isolation control measures to reduce the incidence of healthcare-associated infection.
