As a commonly used clinical herb, Ligustri Lucidi Fructus is renowned for its effects in nourishing the liver and kidneys, improving vision, and darkening hair. Its preparation originated from the "steaming on rice" method in the Song Dynasty. After centuries of inheritance and development, it has evolved into the diverse processing techniques used today. Ancient methods primarily included cleaning, cutting, soaking, honey-roasting, and steaming, while baking-though documented-was not a mainstream practice. Modern techniques have inherited traditional approaches such as cleaning, steaming, and roasting, while diversifying into specifications like wine-steaming, wine-stewing, plain steaming, vinegar-steaming, salt-roasting, and ultra-fine granules. However, variations in critical parameters, such as auxiliary material ratios and steaming duration across regions, have led to inconsistencies in the quality of processed Ligustri Lucidi Fructus. Notably, region-specific methods warrant further exploration, as they may embody unique processing principles and advantages with potential value for enhancing efficacy and quality. By systematically reviewing the historical evolution and regional variations of processing techniques for Ligustri Lucidi Fructus, key issues such as inconsistent processing parameters were identified, which provided a reference for the standardization of processing procedures and the improvement of quality standards.

Objective To observe the effects of the chronic adventitia injury on the vasoconstriction of the rat carotid artery. Methods A non-occlusive silicone collar was positioned around the right carotid artery of rats. Blood flow and vascular reactivity to 5-HT were examined, and both carotids were harvested for morphometry at day 3,7 and 14 after operation. Results In the early stage of advenfitia injury induced by positioning a silicone collar around file rat carotid artery, there appeared the characteristic histological changes of chronic vasospasm in collared artery, such as the reduction of the luminal area for (12.15±2.29)% at day 3 after operation (P =0.003 ) and (45.17±3.84)% at day 7 (P 〈 0.001 )] ,corrugation of the internal elastic lamina,medial thickening up to [ (23.04±5.96)% at day 3 (P =0.009), (61.65±10.32)% for day 7 (P 〈 0.001 )] ,the reduction of the blood flow and the increase of vascular reactivity to 5-HT when compared to con- tralateral arteries. Two weeks after collar placement, the vascular wall remodeling was observed in injured artery, such as the medial thickening for [(31.52±4.56) %,P =0.012] and a diffuse intimal hyperplasia,the reduction of the lunfinal area [(37.17±4.57)% (P 〈 0.001)] and the carotid artery blood flow. The average neointima area was (0.19±0.05) rom2 in collared arteries. The vascular reactivity to 5-HT came back to the normal level. Conclusions Collar-induced advenfitia injury caused the enhancement of vascular contractility and the neointima formation. The change of vascular contractility appeared before the formation of neointima.

Objective To evaluate the performance of modified Hodge test on the detection of carbapenemases among Enterobacteriaceae with decreased susceptibility to carbapenems. Methods Fortynine Enterobacteriaceae isolates with decreased susceptibility to carbapenems ( MIC of imipenem, meropenem or ertapenem was ≥ 2 μg/ml ) were collected from 16 teaching hospitals from 2004 to 2008. MICs of imipenem, meropenem and etapenem were determined by agar dilution method. Carbapenemases were detected by modified Hodge test. Carbepenemase-causing positive results and AmpCs-causing positive results were differentiated by phenyl boronic acid and oxacillin. Beta-lactamases encoding genes including blaNDM-1were detected by PCR and sequencing. Results Thirty-six of 49 isolates were non-susceptible to imipenem (MIC >4 μg/ml), 31 were non-susceptible to meropenem (MIC > 4 μg/ml) and 47 were non-susceptible to ertapenem (MIC > 2 μg/ml). Twenty-three isolates showed positive modified Hodge test result, including 9 weak-positive results and 14 strong-positive results. Through PCR detection and sequencing, 2 out of 9 isolates showing weak-positive results carried blaKPC-2 and other 7 did not carry any carbapenemase genes but AmpCs/ESBLs genes. Among the 14 isolates showing strong-positive results, 4 carried blaKPC-2, 8 carried blaIMP-4 and 2 caried blaIMP-8. All 26 isolates with negative modified Hodge test result didn't carry any carbapenemase genes. No isolate carried blaNDM-1. Carbapenemases genes PCR detection was regarded as a gold standard, and the sensitivity, specificity, positive predictive value and negative predictive value of modified hodge test was 100%, 79%, 70% and 100% on the detection of carbapenemases among Enterobacteriaceae with decreased susceptibility to carbapenems. Conclusions Modified Hodge test revealed great sensitivity but showed a few false positive results. True and false positive results can be effectively differentiated by phynel boronic acid and oxacillin.
