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.

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.

DNA barcoding identification of commercial decoctions in traditional Chinese medicine / 药学学报

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.

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). It also showed that the expression of the 1-hydroxylase protein in kidney tissues was upregulated at 1 h, 3 h and decreased at 6 h, 12 h compared with the SO group. The serum calcium, 1, 25 dihydroxy vitamin D3 and the expression of the 1-hydroxylase protein in kidney tissues of the SAP group showed sustaining decrease. Western blotting showed positive correlation between the 1-hydroxylase expression and serum calcium at 3 h, 6 h and 12 h (r=0.976, P<0.001; r=0.948, P<0.001; r=0.742, P=0.001) and also positive correlation between the 1-hydroxylase expression and serum 1, 25 dihydroxy vitamin D3 at 1 h, 3 h, 6 h and 12 h (r=0.935, P<0.001; r=0.952, P<0.001; r=0.917, P<0.001; r=0.874, P<0.001). Conclusions: At the early stage of the kidney injury, the expression of 1-hydroxylase in the kidney tissue is reduced with the progress of the disease and the decrease in its activity has a correlation with the hypocalcaemia.

Active screening and risk factors for colonization of multidrug-resistant or-ganisms in a surgical intensive care unit / 中国感染控制杂志

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.

Synthesis and protective effect of ligustrazine intermediates against CoCl2-induced neurotoxicity in differentiated PC12 cell / 中国中药杂志

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.

Effects of low-level lead exposure on the neurobehavioral development of infants and early intervention / 中华预防医学杂志

<p><b>OBJECTIVE</b>To explore the effects of low-level lead exposure on infant's neurobehavioral development and evaluate the effects of early intervention.</p><p><b>METHODS</b>The study population consisted of 276 infants whose blood lead, cadmium, iron, zinc, copper, magnesium and calcium concentrations were measured by atomic absorption spectroscopy and developmental status were assessed using the Gesell developmental Diagnosis scales (GDDS) at 6 months of age. All study subjects was divided into three groups: 58 infants in control group, 162 infants in low lead group and 56 infants in high lead group. On the basis infants of both the low and high lead groups were provided with interventional measures for 3 months, and tests for the blood lead, cadmium, iron, zinc, copper, magnesium, calcium and GDDS were repeated for all infants both 12 and 18 months of ages.</p><p><b>RESULTS</b>Infant' s developmental outcome revealed the developmental quotient was the lowest in the high lead group (86.74 +/- 9. 35), the lesser low in the low lead group (91.52 +/- 10.12) and the highest in control group (100.71 +/- 6.92). Changes in developmental quotient were detected in both the low and high lead groups with statistical significance (P < 0.05) after intervention measures adopted. However, the changes of developmental quotient were more remarkable in the low lead group and after the 18th month there was no statistical significance than control group (t = 1.721, P > 0.05) while the significant difference was found in between the high lead group and the control group (t = 23.495, P < 0.05).</p><p><b>CONCLUSION</b>Low-level lead exposure interfered infant's neurobehavioral development and early intervention might improve infant's developmental quotient.</p>
