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.

Aim To investigate the effect of curcumin against high-fat-diet induced C57BL/6J mice bone changes and the correlation between the expression of cathepsin K and curcumin.Methods Curcumin treated C57BL/6J mice had been on high fat diet for 12 weeks.The HE, Alizarin red S staining and Safranin O/fast green staining of femur were employed to evaluate bone microstructure, bone metabolism and bone development.The expressions of cathepsin K were assessed by Western blot and immunohistochemical staining.Results Histopathological results showed that curcumin could improve the destruction of trabecular bone structure, cartilage development and bone calcification.Biomechanical results proved that curcumin could improve the bone strength of the type 2 diabetic mice induced by high fat.The results of immunohistochemistry and Western blot assay indicated that curcumin could significantly inhibit the expression of cathepsin K in bone tissues of mice.Conclusion Curcumin can increase bone strength, improve bone microstructure, and enhance the degree of bone calcification, which may be achieved by inhibiting the expression of cathepsin K.

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 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). Conclusion 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.

As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

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.

Objective: To determine the effects of ginsenoside rg3 on the body weight of C57BL/6J obese mice and to investigate its underlying weight loss mechanisms with a focus on white fat browning-related factors. Methods: Eight-week-old C57BL/6J male mice were fed a high-fat diet for 12 successive weeks to construct the obese model. C57BL/6J male mice were fed a standard chow diet to construct normal control group. After 8 weeks of intervention with ginsenoside rg3, the food intake, body weight, body fat mass, blood sugar, and lipid profiles of the mice in each group were detected. Hematoxylin and eosin (HE) staining was used to observe the histological morphology of the adipose tissues. Real-time poly-merase chain reaction (RT-PCR) and Western blotting (WB) were applied to detect the gene and protein expression levels of peroxisome proliferators-activated receptor gama (PPARγ), Peroxisome proliferator-activated receptor-gamma coactivator -1alpha (PGC-1α), PR domain containing 16 (PRDM16), and uncoupling protein 1 (UCP-1).Results: Compared to normal control group mice, the body weight, food intake, body fat composition, and blood lipid levels of model group mice increased significantly. After 8 weeks of intervention with ginsenoside rg3, body weight, body fat composition, food intake, and blood lipid profiles decreased. HE staining showed that ginsenoside rg3 can improve white adipocyte hypertrophy to a certain extent. RT-PCR and WB demonstrated that ginsenoside rg3 can increase the mRNA and protein expression levels of PPARγ, PGC-1α, PRDM16, and UCP-1 in the adipose tissues of obese mice. Conclusion: The weight reduction effect of ginsenoside rg3 may be related to the promotion of white fat browning.

Background and Objective Accurate diagnosis of mucous cystic lesion(PCL)remains a clinical difficult.Both Carcinoembryonic antigen(CEA)and glucose(GLU)are reported to have ability to distinguish mucinous PCL from non-mucinous PCL,but the accuracy was limited.The objective of this study was to evaluate the value of cystic CEA combined with GLU in the diagnosis of mucinous PCL.Methods PCL patients who underwent pancreatic surgery and endoscopic ultrasonography guided fine-needle aspiration(EUS-FNA)were retrospectively collected from the First Affiliated Hospital of Naval Medical University.Clinical data and cystic fluid analysis of included PCLs patients were analyzed using receiver operator(ROC)curves.ROC analysis,sensitivity and specificity analyses were used to evaluate the value of CEA combined with GLU in the diagnosis of mucinous PCL.Results From January 2015 to December 2021,a total of 84 patients underwent cyst fluid CEA and GLU analysis,of whom 44(52.4％)had mucinous PCL and 40(47.6％)had non-mucinous PCL.The AUC for distinguishing mucinous from non-mucinous PCL by CEA was 0.82[(95％confidence interval(CI):0.72-0.92)].When 192 ng/mL was used as the cutoff level,the diagnostic sensitivity and specificity were 50％and 93％,respectively.Using 20 ng/mL as cutoff level,the diagnostic sensitivity increased to 80％and the specificity decreased to 68％.The AUC for the cystic GLU to distinguish mucinous from non-mucinous PCL was 0.73(95％CI:0.99-0.87),and the diagnostic sensitivity and specificity were 100％and 60％,respectively.When the cutoff level of CEA was 192 ng/mL,the AUC of CEA combined with GLU in the diagnosis of mucinous PCLs was 0.94(95％Cl:0.86-0.99),while when the cutoff level of CEA was 20 ng/mL,the AUC of CEA combined with Glu in the diagnosis of mucinous PCLs was 0.94(95％CI:0.85-0.99).The AUCs were significantly higher than the AUC with single diagnostic indicators.Conclusion When using the cutoff level of 192 ng/mL,cyst fluid CEA combined with GLU has high sensitivity and specificity in differentiating mucinous PCL from non-mucinous PCL,so it can be considered for clinical application.Lower CEA cutoff level(20 ng/mL)can improve the sensitivity of diagnosis.
