ABSTRACT

OBJECTIVE@#To evaluate the antidiarrheal effect of ethanol extract of Glycyrrhiza uralensis Fisch root (GFR) in vivo and jejunal contraction in vitro.@*METHODS@#In vivo, 50 mice were divided into negative control, positive control (verapamil), low-, medium- and high-dose GFR (250, 500, 1,000 mg/kg) groups by a random number table, 10 mice in each group. The antidiarrheal activity was evaluated in castor oil-induced diarrhea mice model by evacuation index (EI). In vitro, the effects of GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) on the spontaneous contraction of isolated smooth muscle of rabbit jejunum and contraction of pretreated by Acetylcholine (ACh, 10 µmol/L) and KCl (60 mmol/L) were observed for 200 s. In addition, CaCl2 was accumulated to further study its mechanism after pretreating jejunal smooth muscle with GFR (1 and 3 g/L) or verapamil (0.03 and 0.1 µmol/L) in a Ca2+-free-high-K+ solution containing ethylene diamine tetraacetic acid (EDTA).@*RESULTS@#GFR (500 and 1,000 mg/kg) significantly reduced EI in castor oil-induced diarrhea model mice (P<0.01). Meanwhile, GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) inhibited the spontaneous contraction of rabbit jejunum (P<0.05 or P<0.01). Contraction of jejunums samples pretreated by ACh and KCl with 50% effective concentration (EC50) values was 1.05 (0.71-1.24), 0.34 (0.29-0.41) and 0.15 (0.11-0.20) g/L, respectively. In addition, GFR moved the concentration-effect curve of CaCl2 down to the right, showing a similar effect to verapamil.@*CONCLUSIONS@#GFR can effectively against diarrhea and inhibit intestinal contraction, and these antidiarrheal effects may be based on blocking L-type Ca2+ channels and muscarinic receptors.

ABSTRACT

Objective:To investigate the prognostic value of systemic immune-inflammation index (SII) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:The clinical data, including age, gender, complications, laboratory examination results post-admission, SII, model for end-stage liver disease (MELD) score, MELD-Na score, Child-Turcotte Pugh (CTP) score of HBV-ACLF patients treated in Huashan Hospital, Fudan University from January 2016 to August 2021 were retrospectively analyzed. The patients were divided into survival group and death group according to the outcome at 90 days of follow-up.Paired sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis.Pearson correlation was used to analyze the correlation between SII and the prognosis prediction model of HBV-ACLF. The area under the curve (AUC) was used to analyze the clinical efficacies of SII, MELD score, MELD-Na score and CTP score in predicting the prognosis of HBV-ACLF patients, and the optimal cut-off value of SII for predicting the prognosis of HBV-ACLF was calculated. Kaplan-Meier method was used for survival analysis. Results:A total of 140 patients with HBV-ACLF were included. There were 88 patients in the survival group, including 65 males and 23 females, with the age of (47.69±11.96) years. There were 52 cases in the death group, including 40 males and 12 females, with the age of (52.73±12.22) years. The age, aspartate aminotransferase, total bilirubin, serum creatinine, international normalized ratio, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, SII, MELD score, MELD-Na score, CTP score and the incidence of infection in the death group were all significantly higher than those in the survival group, and albumin, lymphocyte count, platelet count, prognostic nutritional index in the death group were all significantly lower than those in the survival group, and the differences were all statistically significant ( t=-2.39, Z=-2.84, t=-4.81, Z=-2.15, Z=-4.91, Z=-3.47, Z=-3.36, Z=-3.83, Z=-4.69, Z=-4.56, Z=-6.31, χ2=24.96, t=3.06, t=3.03, Z=-7.57 and t=4.12, respectively, all P<0.05). Pearson correlation analysis showed that SII was positively correlated with CTP score ( r=0.272 7, P=0.001), MELD score ( r=0.365 8, P<0.001) and MELD-Na score ( r=0.381 1, P<0.001). The AUC of SII was the largest of 0.80, and 0.76 for MELD score, 0.74 for MELD-Na score and 0.73 for CTP score. The optimal cut-off value of SII was 447.49. Kaplan-Meier analysis showed that the 90 days survival rate of patients with SII≥447.49(38.60%(22/57)) was lower than that of SII<447.49 group (79.52%(66/83)), and the difference between the two groups was significant ( χ2=23.80, P<0.001). Conclusions:SII can be used to assess the severity and prognosis of HBV-ACLF patients. SII ≥447.49 indicates poor prognosis.

ABSTRACT

Background: Hepatic encephalopathy (HE) is one of the main causes of death in patients with end-stage liver disease. Early evaluation of the condition of patients with liver cirrhosis complicated with HE is the key for improving the prognosis. Aims: To investigate the effects of controlling nutritional status (CONUT) and CTP score on predicting the short term prognosis of liver cirrhosis patients complicated with HE. Methods: The clinical data of 168 liver cirrhosis patients complicated with HE initially diagnosed in Nantong Third People's Hospital from January 2018 to December 2021 were enrolled and analyzed retrospectively. HE patients were divided into survival group and death group. Cox regression analysis was used to evaluate the risk factors affecting the prognosis. A new prediction model was established, and ROC curve was used to evaluate the values of different models for short⁃term prognosis of HE patients. Survival was evaluated by Kaplan⁃Meier method. Results: Compared with survival group, ALT, AST, TBIL, INR, white blood cell count, neutrophil were significantly increased in death group (P<0.05), while ALB, total cholesterol, serum Na, fibrinogen, lymphocyte were significantly decreased (P<0.05). CONUT (OR=1.499, 95% CI: 1.092⁃2.057, P=0.012), CTP score (OR=1.474, 95% CI: 1.178⁃1.844, P=0.001) were independent risk factors for 90⁃day mortality in liver cirrhosis patients complicated with HE. AUC of CTP, CONUT and CONUT⁃CTP scoring models were 0.90, 0.94 and 0.95, respectively. Kaplan⁃Meier analysis showed that the survival rate in CONUT⁃CTP≥7.50 group was significantly lower than that in <7.50 group (P<0.000 1). Conclusions: CONUT⁃CTP score has good predictive value for the prognosis of liver cirrhosis patients complicated with HE, CONUT⁃CTP ≥7.50 indicates poor prognosis.

ABSTRACT

Objective:To analyze the risk factors for postoperative pancreatic fistula after pancreaticoduodenectomy (PD).Methods:The clinical data of 185 patients undergoing PD who were admitted to the Hepatobiliary and Pancreatic Surgery Center of First Affiliated Hospital of Anhui Medical University from January 2014 to December 2018 were retrospectively analyzed. Risk factors for pancreatic fistula after PD were investigated using univariate and multivariate logistic regression analyses.Results:Among 185 patients, pancreatic fistula occurred in 37 patients after PD, and the incidence was 20.0%. Of 34 patients (18.4%) developed grade B pancreatic fistula, and 3 patients (1.6%) developed grade C pancreatic fistula. There were two deaths directly related to postoperative pancreatic fistula (5.4%). Patients with grade B and C postoperative pancreatic fistula had significantly increased hospitalization time and medical expenses. Univariate analysis identified that pancreatic duct diameter ≤3 mm, soft pancreas and serum albumin ≤30 g/L(χ 2=7.236, 6.948, 8.063, all P<0.05) were risk factors for pancreatic fistula after PD. Multivariate logistic regression analysis identified that pancreatic duct diameter≤3mm, soft pancreatic texture and serum albumin ≤30 g/L ( OR=0.401, 0.629, 0.326, 95% CI 0.167-0.968, 0.411-0.963, 0.150-0.711, all P<0.05) were independent risk factors for pancreatic fistula after PD. Postoperative pancreatic fistula patients had a median survival time of 827.0 days, 1-year survival rate was 94.7%, and a 3-year survival rate was 35.8%. There was no significant correlation between postoperative pancreatic fistula and postoperative survival(χ 2=1.367, P=0.242). Conclusions:Patients with a smaller pancreatic duct diameter (≤3 mm), soft pancreatic texture, and low postoperative albumin(≤30 g/L) may have a high incidence of pancreatic fistula after PD. Postoperative pancreatic fistula did not significantly affect the patients′ long-term survival.

ABSTRACT

Objective:To investigate the incidence and related risk factors related to early postoperative complications after hepaticojejunostomy surgery for iatrogenic bile duct injury.Methods:A retrospective analysis was made on the data of 110 cases undergoing a hepaticojejunostomy at the First Affiliated Hospital of Anhui Medical University and Anhui Provincial Hospital from January 2001 to December 2018. The univariate and multivariate analyses were performed to explore the impact risk factors on the short-term complications.Results:Patients′ median age was 44 years old. The short-term postoperative complication rate was 35.5% and the serious complication rate was 17.3%. Univariate analysis showed that male, a failed repair was attempted before referral, intraoperative bleeding>400 ml, and duration of surgery were significantly related to the occurrence of early postoperative complications (all P<0.05). Multivariate analysis showed that male, pre-referral failed surgical repair, preoperative bile leakage, initially combined with hepatectomy, and intraoperative bleeding>400 ml were independent risk factors for postoperative short term complications (all P<0.05). Univariate and multivariate analysis of early postoperative severe complications(Clavien-Dindo≥Ⅲ) revealed that pre-referral surgical repair, combined liver resection, and intraoperative bleeding>400 ml can significantly affect the occurrence of early postoperative severe complications (all P<0.05) . There was no significant correlation between the timing of biliary repair and the occurrence of complications ( P>0.05). Conclusions:Upon the occurrence of iatrogenic bile duct injury, the surgeon is advised to refrain from doing a repair instead sending the patient to a referral hospital. If bile leakage persists before surgery, sufficient bile drainage should be given priority to control infection.

ABSTRACT

Background: Acute-on-chronic liver failure (ACLF) is a rapid-developing critical illness with a high mortality. Accurate prediction of the prognosis of patients with ACLF can guide the individualized therapy, and effectively and rationally utilize the scarce liver source. Aims: To investigate the short-term prognostic value of ALBI, NLR, FIB-4, and MELD score in ACLF patients undergoing plasma exchange (PE). Methods: A retrospective analysis was conducted on clinical data of consecutive patients with ACLF undergoing PE from Jan. 2015 to Jul. 2019 at the Nantong Third People's Hospital. According to the survival status at 3 months after admission, the eligible cases were allocated into improvement group and deterioration group (including clinical deterioration, liver transplantation and death cases). The laboratory parameters before PE were recorded to calculate the score of ALBI, NLR, FIB-4, and MELD. Multivariate logistic regression analysis was performed to identify the influencing factors for prognosis and a combined prognostic model was constructed. ROC curve was used to assess the performance of single and combined score for predicting the short-term prognosis. Results: A total of 147 ACLF patients were enrolled, 71 in improvement group and 76 in deterioration group. ALBI, NLR, FIB-4, and MELD score were all significantly increased in deterioration group than in improvement group (P<0.05). Multivariate logistic regression analysis revealed that all four single score were independent risk factor for poor short-term prognosis of ACLF patients undergoing PE. Area under the ROC curve (AUC) was 0.767, 0.884, 0.750 and 0.860 for ALBI, NLR, FIB-4, and MELD, respectively. When using triple (ALBI+NLR+FIB-4) or quadruple (ALBI+NLR+FIB-4+MELD) combined score established by logistic regression model, AUC could increase to 0.918 and 0.946, respectively. Conclusions: ALBI, NLR, FIB-4, MELD score has a good value for evaluating the short-term prognosis of ACLF patients undergoing PE. Combined model including these four single score has higher predictive value.

ABSTRACT

To investigate the potential hypoglycemic effect of nanosuspensions of honokiol and explore the underlying mechanisms, a high fat diet (HFD) was studied in C57BL/6J mice divided into five groups: normal diet (ND), HFD, HFD/honokiol-sodium carboxymethyl cellulose (CMC-Na) (Hono-CMC, 100 mg·kg-1), HFD/honokiol- Nano (Hono-Nano, 80 mg·kg-1), HFD/metformin (HFD/Met, 200 mg·kg-1). Fasting blood glucose (FBG) and body weights (BW) of mice were measured every seven days. After 30-day treatment, an oral glucose tolerance test (OGTT) was performed, and blood and tissue samples were collected for analysis. All animal experiments were approved by the Research Animal Care Committee of Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine. The data showed Hono-Nano and metformin reduced FBG, BW, and markedly improved OGTT of mice compared to HFD group (P<0.05). Hono-CMC produced nonsignificant impact on FBG, BW of mice, while OGTT of mice was improved by Hono-CMC (P<0.05). Meanwhile, none of these treated groups showed significant effects on regulating serum insulin levels, but all of them exhibited decreased serum glucagon levels notably compared to the HFD group (P<0.05). Western blot analysis revealed that honokiol up-regulated levels of p-AMPK and p-FOXO1 in liver tissue of HFD mice (P<0.05), which resulted in activation of AMPK and inhibition of FOXO1. Moreover, the expression of PEPCK (a key enzyme of gluconeogenesis) was decreased by honokiol (P<0.05). Taken together, our findings demonstrate that nanosuspension of honokiol is more effective than CMC-Na-suspension of honokiol on blood glucose controlling in HFD mice. The hypoglycemic effects of honokiol might rely on suppressing hepatic gluconeogenesis via activating AMPK and inhibiting FOXO1.

ABSTRACT

Objective@#To explore the relationship between the tumor necrosis factor receptor superfamily members 11A (TNFRSF11A) and 11B (TNFRSF11B) gene polymorphisms and the outcome of hepatitis C virus (HCV) infection.@*Methods@#In this case-control study, 749 cases of persistent HCV infection, 494 cases of spontaneous clearance and 1 486 control subjects were included from 2008 to 2016. TaqMan-MGB probe method was used to detect the genotype of TNFRSF11A rs1805034 and TNFRSF11B rs2073617. The genotypes distribution of the two single nucleotide polymorphisms (SNP) were analyzed in different populations.@*Results@#Co-dominant model showed that individuals carrying the rs2073617 CC genotype were prone to have chronic HCV infection, compared with individuals carrying the rs2073617 TT genotype (OR=1.517, 95%CI: 1.055-2.181, P=0.024). Recessive model results showed that individuals carrying rs2073617 CC genotype were more likely to develop chronic HCV infection compared with individuals carrying rs2073617 TT or TC genotype (OR=1.435, 95%CI: 1.033-1.996, P=0.032). Additive model showed that the risk for chronic HCV infection increased with the increase of the number of rs2073617 C alleles (OR=1.204, 95%CI: 1.013-1.431, P=0.035).@*Conclusion@#The genetic polymorphism of TNFRSF11B rs2073617 might be related with the chronicity of HCV infection.

ABSTRACT

Objective@#To investigate the tumor necrosis factor receptor superfamily 1B gene (TNFRSF1B) polymorphism in relation to the outcomes of hepatitis C virus (HCV) infection.@*Methods@#One thousand six hundred and forty-five cases without HCV infection, 545 cases with HCV clearance, and 783 cases with chronic HCV infection were enrolled. TaqMan probe method was used to investigate genotype rs1061622 (T > G) and rs1061624 (G > A). Two single nucleotide polymorphisms (SNPs) sites were genotyped and haplotypes were constructed to evaluate their relation with the outcome of HCV infection.@*Results@#Logistic regression analysis showed that there was no relation to the two SNPs with HCV infection susceptibility and chronicity (P > 0.05). Haplotype analysis showed that carrier TA had an increased susceptibility to HCV infection [adjusted odds ratio (OR) = 1.15, 95% confidence interval (CI): 1.01 to 1.30, P = 0.038)]. Carrier TA and GG haplotypes were conducive to chronic HCV infection (adjusted OR = 1.28, 95% CI: 1.08 to 1.53, P = 0.006; OR = 1.31, 95% CI: 1.03 to 1.66, P = 0.026).@*Conclusion@#The combinational effects of rs1061622 and rs1061624 in TNFRSF1B gene may increase the risk of HCV chronicity and infection.

ABSTRACT

BACKGROUND: Sj?gren's syndrome (SS) is a chronic progressive autoimmune disease. The incidence of peripheral nervous system damage in patients with primary Sj?gren's syndrome (pSS) is 10%-30%. Previous studies have shown that there are multiple electrophysiological manifestations in patients with pSS presenting with peripheral neuropathy. However, there is no consensus on its neuroelectrophysiological manifestations. Peripheral neuropathy associated with pSS is easily confused with peripheral neuropathy caused by other etiologies. OBJECTIVE: To observe the neuroelectrophysiological manifestations of peripheral neuropathy associated with pSS to assist in the diagnosis of the disease. METHODS: A total of 100 pSS patients with peripheral neuropathy who receive treatment in the Department of Neurology, First Affiliated Hospital of Kunming Medical University, in China will be included in this study. Fifty-two patients included in the preliminary experiment presented with peripheral neuropathy associated with pSS. The primary outcome measure is the rate of abnormal motor nerve conduction velocity. The secondary outcome measures include the rate of abnormal terminal motor latency, the rate of abnormal compound muscle action potential amplitude, the rate of sensory nerve conduction velocity, the rate of abnormal sensory nerve action potential amplitude, the rate of abnormal F wave, and the rate of abnormal sympathetic skin response. RESULTS AND CONCLUSION: Results of 52 patients included in the preliminary study showed that the rate of each electrophysiological index was similar between upper and lower extremities; the rate of abnormal motor nerve conduction velocity was significantly higher than the rate of abnormal compound muscle action potential amplitude; the rate of sensory nerve conduction velocity was significantly higher than the rate of abnormal sensory nerve action potential amplitude; the rate of abnormal motor nerve conduction velocity was similar to the rate of abnormal sensory nerve conduction velocity; the rate of abnormal compound muscle action potential amplitude was similar to the rate of abnormal sensory nerve action potential amplitude; the rate of abnormal wave was significantly lower than the rate of abnormal motor nerve conduction velocity; the rate of abnormal sympathetic skin response was similar to the rate of abnormal motor nerve conduction velocity. Results from this study will reveal neuroelectrophysiological abnormality in peripheral neuropathy associated with pSS, which will help diagnose the disease.

ABSTRACT

In 2016, a severe leaf spot disease was found on Iris ensata Thumb. in Nanjing, China. The symptom was elliptical, fusiform, or irregularly necrotic lesion surrounded by a yellow halo, from which a small-spored Alternaria species was isolated. The fungus was identified as Alternaria iridiaustralis based on morphological characteristics. The pathogenicity tests revealed that the fungus was the causal pathogen of the disease. Phylogenic analyses using sequences of ITS, gpd, endoPG, and RPB2 genes confirmed the morphological identification. This study is the first report of A. iridiaustralis causing leaf spots on I. ensata in China.

OBJECTIVE Transient outward potassium current (Ito) plays a crucial role in cardiac phase 1 repolarization and the channels are assembled by pore-forming α-subunits (Kv4.2 or Kv4.3) and auxiliary subunits (KChIP2 and DPP6). Previous studies have found that the compound NS5806 increases Ito in canine ventricular cardiomyocytes through slowing current decay. Here, we reported that NS5806 produced an acute inhibitory action on Ito in mouse ventricular cardiomyocytes and human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CM). METHODS Whole-cell patch-clamp was used to record Ito in native myocytes and in HEK cells expressing cloned Kv4.x/KChIP2/DPP6 channels; Western-blot detected the channel protein expression. RESULTS In isolated mouse ventricular cardiomyocytes, NS5806 (0.1-30 μmol·L-1) inhibited Ito in a concentration-dependent manner with IC50 of 6.6±1.9 μmol·L-1. The current decay was significantly accelerated with a time constant from 53.8±5.5 to 41.8±3.0 ms at +60 mV (P<0.01). Similarly, NS5806 concentration-dependently reduced the Ito peak current amplitude with an acceleration of current decay. In addition, NS5806 increased IKv4.2/KChIP2 and delayed current decay, but decreased IKv4.2/KChIP2/DPP6 with the acceleration of current decay. The inhibitory action on the current was more potent if DPP6 expression level was increased from Kv4.2/KChIP2/DPP61:1:1 to 1:1:3. Western-blot showed a higher expression of DPP6 protein in mouse heart and in hiPS- CM compared to canine heart. Moreover, specific knock- down DPP6 expression by siRNA antagonized the inhibitory action of NS5806 in hiPS-CM. Our results pointed to an important role of DPP6 subunit in the regulation of NS5806 on the channel. By using molecular docking simulation, five interaction sites with high possibility between KChIP2 and DPP6 were identified. Mutations of those sites changed the inhibitory action of NS58056 into excitatory effect on the current with the delay of current decay. CONCLUSION NS5806 significantly inhibits Ito by accelerating current decay in mouse cardiomyocytes and hiPS-CM. The effect depends on the interaction between DPP6 and KChIP2 subunits.

ABSTRACT

BACKGROUND: Percutaneous vertebroplasty (PVP) has been proved to be effective for osteoporotic vertebral compression fractures (OVCF); however, bone cement leakage-related complications occur frequently. OBJECTIVE: To systematically evaluate the safety and complications of PVP with high-viscosity and low-viscosity bone cement in the treatment of OVCF. METHODS: We performed a systematic search by computer in PubMed, EMBASE, Cochrane Library (December, 2016) and CNKI, CBM, VIP and WanFang databases from January, 2000 to December, 2016; meanwhile, the relevant Chinese and English orthopedic journals were retrieved manually. Randomized controlled trials (RCTs) concerning the use of high-viscosity and low-viscosity bone cement in the PVP for OVCF were collected and systematically reviewed using the method recommended by the Cochrane Collaboration. The Meta-analysis was performed by using the RevMan5.2. RESULTS AND CONCLUSION: Six relevant RCTs were included, involving 554 patients (high-viscosity bone cement was used in 278 cases and low-viscosity bone cement in 276 cases). Meta-analysis results showed that postoperative pain symptoms were alleviated in all the 554 cases, and there was no significant difference in the amount of adjacent vertebral fractures between two approaches (P > 0.05). However, there was a significant difference in the visual analog scale score, Oswestry disability index value, Cobb angle, and bone cement leakage rate between high-viscosity and low-viscosity cement groups (P < 0.05). To conclude, PVP with either high-viscosity or low-viscosity bone cement can relieve pain rapidly in OVCF patients, and both approaches are safe and effective. However, high-viscosity bone cement has a lower cement leakage rate and better outcomes in visual analog scale score, Oswestry disability index, Cobb angle and cement leakage prevention as compared with low-viscosity bone cement.

ABSTRACT

AIM: To investigate the role of autophagy in the apoptosis of human pulmonary artery endothelial cells (HPAECs) induced by cigarette smoke extract (CSE).METHODS: HPAECs were cultured routinely.HPAECs were treated with CSE at different concentrations, and the cell viability was detected by MTT assay.HPAECs were divided into control group, CSE group, 3-methyladenine (3-MA) group and 3-MA+CSE group.The autophagy was observed under fluorescence microscope with monodansylcadaverine (MDC) staining.Annexin V/propidium iodide staining and Hoechst 33342 staining were employed to detect apoptosis.In addition, the protein levels of LC3, beclin-1 and cleaved caspase-3 were determined by Western blot.RESULTS: MDC staining showed the increased production of autophagic vacuoles was observed in CSE group.The results of Western blot showed that the expression levels of autophagy-related proteins LC3 and beclin-1 were increased, while 3-MA pretreatment inhibited the expression of these proteins and the production of autophagic vacuoles.Observation with Annexin V/propidium iodide staining and Hoechst 33342 staining showed that the apoptotic rate in CSE group was significantly higher than that in control group, and pretreatment with 3-MA induced further increase in the cell apoptosis.The protein level of cleaved caspase-3 in CSE group was significantly higher than that in control group (P<0.05), and 3-MA+CSE treatment induced the further increase in the protein level of cleaved caspase-3.CONCLUSION: CSE induces autophagy and apoptosis in the HPAECs.Inhibition of autophagy promotes the apoptosis induced by CSE in HPAECs, which can be achieved through activation of caspase-3.

ABSTRACT

Objective To observe expression levels of N-methyl-D-aspartate (NMDA) receptor and cholecystokinin (CCK) in the hippocampus and spinal cord in morphine withdrawal or tolerance mice treated by electroacupuncture or catgut embedding and explore the difference between the regulating effects of electroacupuncture and catgut embedding on morphine withdrawal and tolerance.Methods Fifty-six male C57BL/6J mice were randomly allocated to withdrawal control, withdrawal model, withdrawal catgut embedding and withdrawal electroacupuncture groups, and tolerance control, tolerance model, tolerance catgut embedding and tolerance electroacupuncture groups, 7 mice in each group. A model of morphine withdrawal was made by subcutaneous injection of morphine hydrochloride using 7-day increasing addiction method. The withdrawal control group was injected with an equal volume of normal saline at the same time points. In the withdrawal electroacupuncture group, electroacupuncture at bilateral points Shenshu was performed using a Han’s acupoint nerve stimulation device (HANS-200) at 15 min after an injection of morphine hydrochloride. In the withdrawal catgut embedding group, 0.5 cm chromic catgut was embedded in bilateral points Shenshu at 15 min after an injection of morphine hydrochloride. Addiction was promoted by intraperitoneal injection of naloxone 4 mg/kg at 10 o’clock on the seventh day’s morning and Withdrawal reactions were observed in the mice. The score was recorded using the Ryuta Tomoji opioid withdrawal symptoms evaluation scale. NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by enzyme-linked immunosorbent assay (ELISA). A model of morphine tolerance was made by subcutaneous injection of morphine 10 mg/kg. The tolerance control group was injected with tolerance normal saline 10 ml/kg at the same time. In the tolerance catgut embedding group, catgut was embedded in point Shenshu at the first day after model making. In the tolerance electroacupuncture group, point Shenshu was given electroacupuncture at the first day after model making. After seven days of treatment, NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by ELISA.Results There were statistically significant differences in hippocampal NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There was a statistically significant difference in hippocampal NR2B expression between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the withdrawal catgut embedding or withdrawal electroacupuncture group and the withdrawal model group (P<0.05). There were statistically significant differences in spinal cord NR2A, NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There were statistically significant differences in spinal cord NR2A and NR2B expressions between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There were statistically significant differences in hippocampal NR2A, NR2B and CCK expressions between the tolerance model and tolerance control groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the tolerance catgut embedding and tolerance model groups (P<0.05). There was a statistically significant difference in hippocampal NR1 expression between the tolerance electroacupuncture group and the tolerance model or tolerance catgut embedding group (P<0.05). There was a statistically significant difference in spinal cord CCK expression between the tolerance catgut embedding or withdrawal electroacupuncture group and the tolerance model group (P<0.05).Conclusions Both catgut embedding and electroacupuncture at point Shenshu have a reducing effect on morphine tolerance and withdrawal. The therapeutic effect of electroacupuncture is better than that of catgut embedding.
