Journal of Guangzhou University of Traditional Chinese Medicine 2015;(4):690-693
Objective To investigate the clinical effect of acupuncture therapy for ascending and descending Qi for the treatment of insomnia with the syndrome of liver stagnation. Methods Sixty quantified patients were randomized into 2 groups, 30 cases in each group. The patients in the treatment group were treated by acupuncture therapy for ascending and descending Qi, and the control group was given conventional acupuncture therapy. The polysomnography ( PSG) results and Pittsburgh sleep quality index ( PSQI) were compared before and after treatment, and the clinical efficacy was evaluated after treatment in the two groups. Results ( 1) The parameters of total sleep time, deep sleep time and rapid eye movement ( REM) time were prolonged, and the sleep latency and waking-up frequency in both groups were reduced after treatment (P<0.05 compared with those before treatment), and the improvement of total sleep time, deep sleep time and REM time in the treatment group was significantly superior to that in the control group (P<0.05). (2) PSQI scores in both groups were reduced after treatment ( P<0.01 compared with those before treatment) , and the reduction in the treatment group was more significant than that in the control group (P<0.01). (3) The total effective rate in the treatment group was 93.33%and was 76.67%in the control group. The efficacy in the treatment group was better than that in the control group (P<0.01). Conclusion Acupuncture therapy for ascending and descending Qi has better effect on insomnia with liver stagnation than conventional acupuncture therapy, being practical and innovative.

In traditional Chinese medicine herbs (TCM), including Radix Salviae Miltiorrhizae (Danshen), Radix Puerariae Lobatae (Gegen), Radix Angelicae Sinensis (Danggui), and Rhizoma Chuanxiong (Chuanxiong) are widely used for the prevention and treatment of cardiovascular diseases and also often co-administered with Western drugs as a part of integrative medicine practice. Carboxylesterase 1 (CES1) plays a pivotal role in the metabolisms of pro-drugs. Since (S)-2-(2-(6-dimethylamino)-benzothiazole)-4,5-dihydro-thiazole-4-carboxylate (NLMe) has recently been identified by us as a selective CES1 bioluminescent sensor, we developed a rapid method using this substrate for the direct measurement of CES1 activity in rats. This bioluminescence assay was applied to determine CES1 activity in rat tissues after a two-week oral administration of each of the four herbs noted above. The results demonstrated the presence of CES1 enzyme in rat blood and all tested tissues with much higher enzyme activity in the blood, liver, kidney and heart than that in the small intestine, spleen, lung, pancreas, brain and stomach. In addition, the four herbs showed tissue-specific effects on rat CES1 expression. Based on the CES1 biodistribution and its changes after treatment in rats, the possibility that Danshen, Gegen and Danggui might alter CES1 ac-tivities in human blood and kidney should be considered. In summary, a selective and sensitive biolu-minescence assay was developed to rapidly evaluate CES1 activity and the effects of orally administered TCMs in rats.

OBJECTIVETo investigate the effect of ceftiofur hydrochloride on the pharmacokinetics of matrine in rats.
METHODThe rats were divided into two groups: one group was administrated with matrine only (control group) and the other was administrated with matrine in combination with ceftiofur hydrochloride. HPLC-UV method was used for determining the plasma concentration of matrine in both groups. The pharmacokinetic parameters were calculated from the plasma concentration-time data using the DAS 2. 1. 1 software program.
RESULTThe main pharmacokinetic parameters for the control group were C(max) = 21.113 9 mg x L(-1), T(max) = 0.75 h, t1/2alpha = 1.34 h, t1/2beta = 3.509 h, AUC(0-t) = 90.984 mg x h(-1) x L(-1) and AUC(0-inifinity) = 100.346 mg x h(-1) x L(-1), and the data for the combination group were C(max) = 11.707 mg x L(-1), T(max) = 0.917 h, t1/2alpha = 1.598 h, t1/2beta = 3.247 h, AUC(0-t) = 53.28 mg x h(-1) x L(-1) and AUC(0-inifinity) = 60.035 mg x h(-1) x L(-1).
CONCLUSIONThe plasma concentration of matrine and bioavailability in combination group were significantly lower than those of the control group. In combination group, matrine had a higher clearance and volume of distribution in the central compartments, as well as a lower volume of distribution in the peripheral compartments.

Objective:
To investigate the clinical application and effect evaluation of failure mode and effect analysis (FMEA) in the optimization of vascular recanalization in patients with ST-segment elevation myocardial infarction (STEMI).
Methods:
A total of 389 STEMI patients admitted to the emergency department of the Fifth Central Hospital in Tianjin from January 2014 to January 2015 were served as the control group, and 398 STEMI patients admitted to the chest pain center of the Fifth Central Hospital in Tianjin from January 2016 to October 2017 were served as the experimental group. In the control group, routine emergency treatment was used. At the same time, the intervention room was 24-hour prepared for emergency vascular recanalization. The experimental group used FMEA. Through the usage of FMEA, the main factors those caused the delay in revascularization treatment were determined, and the revascularization process was optimized for these influencing factors, thereby shortening the "criminal" blood vessel opening time of patients. The door-to-balloon dilatation time (D-to-B time), troponin testing time, placement time of the catheterization room, initiation of the catheterization room to balloon dilatation time, and preoperative and 1 week postoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, heart function parameters [left ventricular ejection fraction (LVEF), left ventricular short axis shortening rate (FS), left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD)] within 1 week, 3 months and 6 months after intervention, and the incidence of main cardiovascular adverse events within 1 month after intervention, hospital mortality, the length of hospital stay, and readmission within 1 year in the patients of two groups were recorded.
Results:
D-to-B time (minutes: 70.6±3.6 vs. 79.4±8.7), troponin testing time (minutes: 17.1±2.3 vs. 65.2±6.5), placement time of the catheterization room (minutes: 28.9±9.8 vs. 52.3±12.2) and activation of the catheterization room to balloon expansion time (minutes: 47.3±9.3 vs. 65.1±7.2) in the experimental group were significantly shorter than those in the control group (all

RESULTS:
D-to-B time (minutes: 70.6±3.6 vs. 79.4±8.7), troponin testing time (minutes: 17.1±2.3 vs. 65.2±6.5), placement time of the catheterization room (minutes: 28.9±9.8 vs. 52.3±12.2) and activation of the catheterization room to balloon expansion time (minutes: 47.3±9.3 vs. 65.1±7.2) in the experimental group were significantly shorter than those in the control group (all P < 0.01). The NT-proBNP levels at 1 week after intervention in the two groups were lower than the preoperative levels, slightly lower in the experimental group, but the difference was not statistically significant. There was no significant difference in cardiac function at 1 week and 3 months after intervention between the two groups. The LVEF and FS at 6 months after intervention in the experimental group were significantly higher than those in the control group [LVEF: 0.622±0.054 vs. 0.584±0.076, FS: (38.1±4.3)% vs. (35.4±6.2)%, both P < 0.01], and LVESD and LVEDD were decreased significantly [LVESD (mm): 31.2±3.8 vs. 34.7±4.2, LVEDD (mm): 49.2±5.3 vs. 52.4±5.6, all P < 0.01]. The length of hospital stay in the experimental group was significantly shorter than that in the control group (days: 8.3±3.2 vs. 13.2±6.8, P < 0.01), the incidence of major cardiovascular adverse events within 1 month after intervention [13.6% (54/398) vs. 19.8% (77/389)], hospital mortality [1.8% (7/398) vs. 4.9% (19/389)], and readmission rate within 1 year [9.5% (38/398) vs. 14.5% (56/389)] in the experimental group were significantly lower than those in the control group (all P < 0.05).
CONCLUSIONS
The usage of FMEA to optimize the vascular recanalization procedure can shorten the emergency treatment time of STEMI patients, reduce the occurrence of adverse events, and improve the prognosis.

Objective:To summarize the electrophysiological characteristics of neuronal intranuclear inclusion disease (NIID) and explore the value of electrophysiological examination in NIID auxiliary diagnosis.Methods:Twenty NIID patients diagnosed by pathological biopsy and genetic confirmation (15 were symptomatic, 5 were asymptomatic), admitted to Department of Neurology, Affiliated Hospital of Xuzhou Medical University from February 2020 to June 2022 were chosen. Peripheral motor/sensory nerve conduction, needle electromyography, F wave, repetitive electrical stimulation, skin sympathetic reflex (SSR), and tremor were analyzed. Peripheral nerve conduction and SSR parameters were compared between 15 patients with symptomatic NIID (symptomatic NIID group) and 11 age- and gender-matched normal control subjects (control group).Results:(1) All 15 patients with symptomatic NIID were with abnormal electrophysiological findings: 14 patients had abnormal peripheral nerve conduction, including 14 with slowed motor nerve conduction velocity (MCV), 4 with reduced composite muscle action potential (cMAP) wave amplitude, 12 with slowed sensory nerve conduction velocity (SCV), and 3 with reduced sensory nerve action potential (sNAP) wave amplitude, and overall slowed nerve conduction velocity and relatively preserved wave amplitude were noted; 4 patients had neurogenic lesions by needle electromyography; 13 patients had prolonged F-wave latency at varied degrees; 12 showed abnormal SSR; 4 exhibited synchronous tremor from 4.0 to 7.5 Hz. (2) In 5 patients with asymptomatic NIID, 3 had abnormal peripheral nerve conduction, including 3 with slowed MCV, 2 with slowed SCV, and 1 with reduced sNAP wave amplitude; 3 showed abnormal SSR. (3) Significant differences in MCV and SCV, some cMAP and sNAP amplitudes, and SSR latency and amplitude were noted in nerves of the upper and lower extremities between the symptomatic NIID group and control group ( P<0.05). Conclusion:Peripheral nerve damages are common in patients with NIID, especially myelin damage and autonomic nerve injury, and some patients may have electrophysiological abnormalities before clinical symptoms; therefore, peripheral nerve conduction and SSR can be recommended as auxiliary screening tools for NIID.

ObjectiveTo count and analyze the toxic traditional Chinese medicines and their characteristics in Chinese Materia Medica, so as to provide reference for the development and application of toxic drugs. MethodThe traditional Chinese medicines included in Chinese Materia Medica were screened one by one, and the inclusion criteria were "drug properties", "usage and dosage" and "major poison, highly poisonous, poisonous, slightly poisonous, slightly poisonous" appearing in ancient books. Standard toxic traditional Chinese medicines were entered into an excel sheet for statistical analysis. ResultA total of 1 408 toxic Chinese medicines were included. The properties and flavors were mainly cold, bitter, pungent and sweet; the main meridians were liver, lung, spleen and stomach; the root, whole grass and leaves were the most used medicinal parts, and there were many toxic drugs. The pre-treatment methods are mainly sun-dried, fresh, fried, calcined, and sunburned; the efficacy categories are mainly heat-clearing drugs, rheumatism drugs, blood-activating and stasis-removing drugs; oral administration methods are mainly decoctions, pills, and powders , mainly for external application, dipping, and coating; the dosage for oral administration is mostly 9-15 g, 3-9 g, 3-6 g, and an appropriate amount is mainly for external use. ConclusionThere are many toxic Chinese medicines clearly recorded in Chinese Materia Medica, but only 83 kinds of clearly toxic Chinese medicines are included in Chinese Pharmacopoeia, which need to be further strengthened by experimental observation and clinical data verification. The clinical application of toxic traditional Chinese medicine is mainly based on heat toxin blood syndrome and rheumatic arthralgia, which is closely related to its nature, taste and meridian return. Able to move, has the effect of activating Qi and activating blood, "sweet" can replenish energy and slow down, and has the effect of tonic, alleviation and pain relief, and mostly used for the treatment of heat syndrome, blood syndrome and arthralgia syndrome. However, there are certain limitations in the classification and processing conditions of toxic traditional Chinese medicines, which need to be further improved and scientifically verified.

ObjectiveTo collect and analyze the properties and application characteristics of external use of roots and rhizomes of Chinese herbal medicines in the Chinese Materia Medica(《中华本草》) to provide data references for the research on clinical external use of Chinese medicine, in order to provide data reference for clinical external use of traditional Chinese medicine(TCM). MethodThe Chinese herbal medicines included in the Chinese Materia Medica were systematically screened. The inclusion criterion was the explicit mention of terms like "root", "rhizome", "root bark", "tuber", "tuberous root", etc. under the "Source" in the Chinese Materia Medica. Information on properties, flavors, meridian tropism, medicinal parts, fresh use, toxicity, efficacies and indications, and dosage of roots and rhizomes of Chinese herbal medicines was collected. The information was then entered into an Excel spreadsheet for statistical analysis. ResultThe Chinese Materia Medica records 2 662 roots and rhizomes of Chinese herbal medicines, of which 1 653 are suitable for external use. The predominant properties and flavors are cool, cold, bitter, pungent, and sweet. These Chinese herbal medicines mainly act on the liver, lung, and spleen meridians. The primary medicinal parts used include root, rhizome, and root bark. More than half of the roots and rhizomes of Chinese herbal medicines can be used in their fresh form. The main efficacies include clearing heat, removing toxins, resolving stasis, dispersing accumulation, resolving blood stasis and stopping bleeding, reducing swelling and alleviating pain, dispelling dampness and relieving pain. The main indications are skin sores, traumatic injuries, and rheumatic diseases. Common external application methods include poultice, decoction for washing, and applying powdered form. Most of these Chinese herbal medicines lack specific dosage guidelines for external use, with an emphasis on using an appropriate amount. ConclusionThe Chinese Materia Medica contains a wide range of roots and rhizomes of Chinese herbal medicines suitable for external use, with definite therapeutic effects, providing a broad perspective for the application of Chinese medicine externally. However, there are still problems such as unclear dosages and limited research. Further studies are necessary to better utilize the advantages of the external use of Chinese medicine.
