ABSTRACT

@#AIM: To evaluate the effect of opaque bubble layer(OBL)on the ocular cylotorsion compensation during FS-LASIK procedures. <p>METHODS: Prospectively clinical study. From July 2019 to September 2019, two-hundred FS-LASIK patients(400 eyes)were randomly included into this study. The total OBL incidence, flap-out OBL incidence, flap-in OBL incidence, incidence of dynamic cyclotorsion component(DCC)and incidence of static cyclotorsion component(SCC)were statistically analyzed. <p>RESULTS: OBL developed in 183 eyes of 400 FS-LASIK eyes, with a total OBL incidence of 45.8%. DCC was successfully performed on 397 eyes, with a total DCC incidence of 99.2%. SCC was successfully performed on 293 eyes, with a total SCC incidence of 73.2%. Neither flap-out OBL nor flap-in OBL could disturb the successful implementation of DCC during the operation(<i>P</i>>0.05). Both flap-out OBL and flap-in OBL could impact the SCC implementation and make it fail(<i>P</i><0.05).<p>CONCLUSION: OBL can result in failure of SCC implementation during the FS-LASIK procedures.

ABSTRACT

Gestational diabetes mellitus(GDM)can cause blood glucose disorders in pregnant women and result in adverse maternal-neonatal outcomes.Vitamin D(VD)can improve glucose tolerance and insulin sensitivity,and thus theoretically,VD supplementation during pregnancy could improve glycemic control as well as maternal-neonatal outcomes in GDM patients.Although studies have shown that VD deficiency is associated with poor maternal-neonatal outcomes in GDM patients,no solid conclusion has been drawn with regard to the effects of VD supplementation on these patients.Therefore,here we summarized the research progress of the effects of VD supplementation on glycemic control and adverse maternal-neonatal outcomes in GDM patients,in an effort to guide the clinical VD supplementation during pregnancy.

ABSTRACT

@#AIM: To evaluate the clinical effect of a limbus protection technique during epithelium-on corneal collagen cross-linking(Epi-on CXL)for keratoconus treatment.<p>METHODS: Prospectively clinical study. A total of 15 patients(30 eyes)with diagnosed binocular progressive keratoconus were selected and treated with Epi-on CXL in my hospital from Jan. to Dec. 2019, and divided into 2 groups, Limbus-protecting Group and Control Group. The differences in corrected distance visual acuity, astigmatism, Km, thickness at the thinnest point of cornea, postoperative discomfort score, corneal epithelium healing time, and tear breakup time were compared between the two groups pre- and postoperatively.<p>RESULTS: The corrected distance visual acuity and astigmatism were improved at 3mo postoperatively(<i>P</i><0.05). The thickness at the thinnest point of cornea and the tear breakup time decreased after Epi-on CXL surgeries(<i>P</i><0.05). No difference was found in parameters of corrected distance visual acuity, astigmatism, Km, thickness at the thinnest point of cornea, tear break up time, and postoperative discomfort sore between the two groups(<i>P</i>>0.05). However, the postoperative corneal epithelium healing time in Limbus-protecting Group was shorter than in Control Group(3.20±0.56d <i>vs</i> 3.73±0.96d, <i>P</i>=0.041).<p>CONCLUSION:This limbal protection technique can reduce the corneal epithelium healing time after Epi-on CXL surgery, which preliminarily shows the feasibility of this technique.

ABSTRACT

Platelet microparticles (PMPs) are membrane particles derived from the platelet membrane that enter into the blood circulation. We sought to explore the therapeutic effects of Tao-Hong-Si-Wu Decoction (THSWD) on angiogenesis in a rat model of cerebral ischaemia-reperfusion (I/R). The protective effect of THSWD on I/R rats was observed morphologically by immunohistochemical expression of VEGF and CD34, along with immunofluorescence results of co-expression of BrdU and vWF. Then, PMPs from different groups of rats were extracted, and cytokine array analysis was used to screen for angiogenesis associated proteins. The results showed that THSWD can promote the expression of VEGF, CD34, BrdU and vWF. Cytokine array analysis revealed the changes in the expression of 29 related angiogenic proteins in the total protein of PMPs, which involved the Notch signalling pathway. Compared with model group, the expression levels of NICD and Hes-1 in the THSWD group were significantly increased. In the context of I/R, the angiogenesis-related proteins of PMPs are different. THSWD may involve the promotion of activation of the Notch signalling pathway to achieve therapeutic effects on cerebral ischaemia.

ABSTRACT

Uranium [U(Ⅵ)] in the blood is known to form stable complexes with apotransferrin (apo-Tf), which plays an important role in mediating the cytotoxicity induced by U(Ⅵ) transported to cells. The present study aimed to establish an new in vitro screening model of U(Ⅵ) decorporation agents through exploring the capability of chelating agents competing with U(Ⅵ) binding to apo-transferrin based on enzyme-linked immunosorbent assay (ELISA). The optimal concentrations of apo-Tf coated antigen, Tf antibody, secondary antibody and U(Ⅵ) treatment were achieved and the stability and reproducibility of this method were validated by methodology study. Using this model, the ability of four chelating agents to mobilize the U(Ⅵ) binding to apo-Tf was evaluated, and the rank of competitiveness was catechol-3,6-bis(methyleiminodiacetic acid) (CBMIDA) ≈ Tiron > apo-Tf > DTPA-CaNa3 ≈ DTPA-ZnNa3. The efficacy of these chelating agents in removal of U(Ⅵ) was tested by animal experiments. The results showed that immediate administration of CBMIDA or Tiron after injection of U(Ⅵ) in mice significantly promoted urinary U(Ⅵ) excretion and reduced U(Ⅵ) accumulation in kidneys and femurs, while DTPA-CaNa3 and DTPA-ZnNa3 have no obvious effects as compared to U(Ⅵ)-exposed mice alone, which was consistent with the results of competitive ELISA method. The animal experiments conform to the rules of the Animal Research Ethics Committee of School of Pharmacy of Fudan University. These results show that the new proposed method is rapid, simple and convenient with good reproducibility and has the potential to be used for in vitro screening of U(Ⅵ) decorporation agents.

ABSTRACT

Objective:To observe the effect of Taohong Siwu granule on dysmenorrhea rats. Method:Forty-eight healthy SD female rats were randomly divided into six groups: control group, model group, Taohong Siwu granule groups (18, 9, 4.5 g·kg-1) and Fuke Qianjin tablet group (0.08 g·kg-1). The rats were given Bugaorer (0.35 mg·kg-1) every day and ice-water bath for 8 minutes for 10 consecutive days. Oxytocin was injected intraperitoneally on the 11th day. The writhing reaction of rats was observed, and the effect of Taohong Siwu granules on hemorheology was measured. The levels of 6-ketoprostacyclin F1α(6-keto-PGF1α), thromboxane B2(TXB2), prostaglandinF2α(PGF2α), PGE2 of rats were detected by enzyme-linked immunosorbent assay (ELISA). Ca2+ in uterine tissues was scanned by laser confocal microscopy. Result:Each dose of Taohong Siwu granule group reduced the number of writhing, the time of writhing and the incidence of writhing in dysmenorrhea rats, which were significantly lower than those in model group (P<0.05,P<0.01). Compared with the model group, high, medium and low-dose Taohong Siwu granules groups could reduce blood viscosity and plasma viscosity, and Taohong Siwu granules can significantly reduce the content of TXB2, Ca2+,PGF2α, and significantly increase the content of 6-keto-PGF1α,PGE2 (P<0.05,P<0.01). Conclusion:Taohong Siwu granule can significantly alleviate dysmenorrhea symptoms in rats. The mechanism may be correlated with the contents of 6-keto-PGF1α, TXB2 and PGF2α, PGE2 and Ca2+.

ABSTRACT

ObjectiveThe pathophysiological changes caused by trauma are complex, and there is still a lack of effective markers for injury monitoring and prognosis judgment. This paper aims to investigate the relationship between neutrophil/lymphocyte ratio (NLR) and lactate level and trauma severity and prognosis in trauma patients.MethodsThe data of 169 trauma patients who met the inclusion criteria in the Department of Emergency Medicine, General Hospital of the Eastern Theater Command from January to December 2017 were retrospectively analyzed. Their gender, age, cause of injury, injury severity score (ISS), acute physiology and chronic health evaluation II (APACHE II), Glasgow coma index (GCS), NLR and lactate levels within 24 hours after the injury and other laboratory results were recorded. According to the ISS score, the patients were divided into mild injury group (ISS<16, n=78), severe injury group (16≤ISS<25, n=53), and critical injury group (ISS≥25, n=38); According to the 28-day outcomes, they were divided into death group (n=22) and survival group (n=147). The correlation between NLR and lactate levels and ISS score was analyzed, and the prognostic value was analyzed by receiver operating characteristic (ROC) curve.ResultsNLR was positively correlated with ISS (r=0.34, P<0.001), and there were significant differences among three trauma groups (P<0.001). Lactate was positively correlated with ISS (r=0.28, P=0.002) too, and significant differences were shown among three trauma groups (P=0.003). The area under the ROC curve of NLR and lactate for predicting 28-day death in trauma patients was 0.785 and 0.686, respectively.ConclusionNLR and lactate are positively correlated with trauma severity and they might play an important part in the early prognosis evaluation of trauma patients.

ABSTRACT

ObjectiveAt present, there are few studies on prognostic indicators for patients with severe traumatic brain injury (STBI). This paper aims to explore its significance by analyzing the demographic characteristics of patients with STBI, as well as parameters such as clinical laboratory test indicators.MethodsA retrospective analysis was performed on 139 STBI patients admitted to the Department of Emergency Medicine, General Hospital of Eastern Theater Command from January 2017 to December 2018. According to the 28-day death event, the participants were divided into the survival group (n=108) and the death group (n=31). Indicators such as Glasgow Coma Score (GCS), red blood cell distribution width (RDW), platelet distribution width (PDW) and clot-related indicators were collected. Univariate and multivariate logistic regression were used to analyze the risk factors related to death, and receiver operating characteristic (ROC) curve was adopted to determine their prognostic values.ResultsThere were significant differences in GCS, RDW and PDW between the two groups. RDW (OR=4.577, 95% CI: 1.704-12.291), PDW (OR=1.346, 95% CI: 1.093-1.657) and GCS (OR=0.469, 95% CI: 0.301-0.730) were risk factors for death of STBI patients. The area under the curve (AUC) of RDW, PDW and GCS scores were 0.735 (0.640-0.840), 0.675 (0.553-0.796) and 0.737 (0.638-0.837), respectively, and the AUC of the combination of the three was 0.840 (0.748-0.932), which was significantly better than that of single diagnosis.ConclusionRDW, PDW combined with GCS can effectively evaluate the prognosis of patients with STBI, which has important guiding value for clinicians′ diagnosis and treatment.

ABSTRACT

OBJECTIVE@#To study the effect of calcium-sensitive receptors (CaSR) on the expression of endothelial nitric oxide synthase (eNOS) and the concentration of nitric oxide (NO) in a neonatal mouse model of persistent pulmonary hypertension (PPH).@*METHODS@#Eighty neonatal C57BL/6 mice were randomly divided into control, PPH, agonist and antagonist groups. The control group was exposed to air, and the other three groups were exposed to 12% oxygen. The agonist and antagonist groups were intraperitoneally injected with a CaSR agonist (GdCl 16 mg/kg) and a CaSR antagonist (NPS2390, 1 mg/kg), respectively, while the PPH and control groups were intraperitoneally injected with normal saline instead. All mice were treated for 14 days. Alveolar development and pulmonary vessels were assessed by hematoxylin-eosin staining. The protein and mRNA expression of eNOS and its localization in lung tissues were determined by Western blot, qRT-PCR and immunohistochemistry. The levels of brain natriuretic peptide (BNP) and NO in lung homogenate were determined using ELISA.@*RESULTS@#Compared with the control group, the PPH and agonist groups showed significant increases in alveolar mean linear intercept, the percent wall thickness of pulmonary arterioles, right to left ventricular wall thickness ratio (RV/LV) and BNP concentration, but a significant reduction in radial alveolar count (P<0.05). The antagonist group had significant improvements in all the above indices except RV/LV compared with the PPH and agonist groups (P<0.05). Compared with those in the control group, the protein and mRNA expression of eNOS and NO concentration were significantly increased in the PPH group and increased more significantly in the agonist group, but were significantly reduced in the antagonist group (P<0.05).@*CONCLUSIONS@#CaSR plays an important role in the development of PPH in neonatal mice, possibly by increasing eNOS expression and NO concentration.

ABSTRACT

The physiology and pathology of the heart and kidney are interdependent and interact with each other, and dysfunction of any one of them causes dysfunction of the other, namely cardiorenal syndrome, in which type I and type Ⅱ have the highest incidence rate and are the commonest in clinic. Traditional Chinese medicine has a long history of treating the cardiorenal syndrome. It believes that the disease is located in the heart and kidney, and Wenyang Yiqi, Huoxue Lishui and other methods shall be adopted to effectively improve the heart and kidney function of patients. However,the pathogenesis of cardiorenal syndrome is complicated, and the clinical manifestations are diverse, which makes it difficult to diagnose and treat in the early stage, and causes missing of the best intervention timing and a poor prognosis. Biomarkers play a vital role in predicting the occurrence and development of cardiorenal syndrome. Therefore, efforts shall be made to look for biomarkers with better specificity and sensitivity, accurately evaluate physiological and pathological changes in heart and kidney, so as to achieve early diagnosis and early intervention of cardiorenal syndrome, and improve the effect of disease diagnosis and treatment. At present, domestic and foreign scholars have studied and applied more markers mainly in renal tubular injury, including neutrophil gelatinase-associated lipocalin, kidney injury molecule-1 and urinary interleukin-18. In addition, other studies have found cell cycle arrest inducing factors, such as insulin-like growth factor binding protein 7, tissue inhibitor metallo proteinase-2, and fibroblast growth factor 23 associated with mineral metabolism. The increase of the content of these biomarkers in the body is earlier than the rise of serum creatinine, which can better predict the occurrence of early cardiorenal syndrome, and has a high application value and research value. After summarization of the biomarkers relating to type I and Ⅱ cardiorenal syndrome in domestic and foreign literatures, the research progress of several representative markers were reviewed to provide reference for related research.

ABSTRACT

Objective:To observe the anti-inflammatory effect of Dendrobii Huoshanense Herba. Method:Totally 60 Kunming mice were randomly divided into normal group, model group, high, middle and low-dose Dendrobii Huoshanense Herba groups (DHS-H, DHS-M, DHS-L, 4, 2, 1 g·kg-1) and dexamethasone acetate group (DXMS, 0.01 g·kg-1). The rats were intragastrically administered for 14 days. After the last administration for 1 h, a total of 20 μL of xylene was added to both sides of the right ear center of the mice to establish the ear swelling model. All of the mice were decapitated 1 h later, and the ear swelling inhibition rate of each group were calculated. Totally 36 healthy SD rats were divided into normal model, model group, DHS-H,DHS-M,DHS-L groups (2.8, 1.4, 0.7 g·kg-1) and DXMS acetate group. The rats were intragastrically administered for 7 days. One hour after the last intragastric administration, a foot swelling model was established through subcutaneous injection of 10%fresh egg white in the right hind limb toe of each group. The right hind paw circumference of each rat was measured at 0, 0.5, 1, 2, 3, 4, 5 h, and the paw swelling of the rats was calculated. Totally 60 SD rats were implanted subcutaneously with sterile dry cotton balls in the bilateral groin and grouped as above. All of the rats were intragastrically administered for 14 days since the next day. After the last administration, cotton balls were taken out, and the inhibition rate of granuloma was calculated. And the contents of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-2 (IL-2), interleukin-6 (IL-6), interferon-γ (IFN-γ) in the serum of each group were detected. Result:Compared with the normal group, the ear swelling rate, the foot swelling degree were significantly increased in the model group(PPPPPα, IL-1β, IL-2, IL-6, and IFN-γ in the model group were higher than those in the normal group (Pα, IL-1β, IL-2, IL-6, and IFN-γ in Dendrobii Huoshanense Herba group and positive drug group were decreased significantly (PPConclusion:Dendrobii Huoshanense Herba could effectively inhibit acute and chronic inflammatory reactions.

ABSTRACT

Objective: To investigate the reproductive protective effect of Duzhong Butiansu Capsule (DBC) by using cyclophosphamide induced spermatogenic disorder model, and explore its mechanism. Methods: The model of spermatogenic disorder was established by intraperitoneal injection of cyclophosphamide (60 mg/kg) for 5 d. Drug intervention at high and low doses (1.388 g/kg and 0.694 g/kg) was given for 4 weeks from the 8th day. The body weight and organ index of each group were measured. The pathological structure of testis was detected by HE staining. ELISA method was used to detect the levels of T, FSH, LH, MDA, SOD, GSH-Px. Western blotting and immunohistochemistry were used to analyze the expression of Nrf2/ARE signaling pathway related factors Nrf2, HO-1, NQO1, HDAC2, and p-PKC in testicular tissue. Results: Compared with the model group, DBC significantly reduced the weight of mice, increased the index of testis, epididymis and kidney, improved the pathological morphology of testis, increased the number of spermatozoa, increased the motility of sperm, decreased the rate of abnormal sperm, increased the level of T and decreasd the level of LH and FSH, increased the content of MDA, decreased the content of SOD and GSH-Px, increased the expression of Nrf2, HO-1, NQO1, HDAC2, and p-PKC protein, and increased the area of positive expression of Nrf2, HO-1 protein (P < 0.05 or P < 0.01). Conclusion: DBC can obviously improve the spermatogenic disorder induced by cyclophosphamide, and the mechanism may be related to the regulation of Nrf2/ARE signal pathway associated with oxidative stress.

ABSTRACT

Objective The level of lactic acid in blood can reflect the degree of ischemia and hypoxia of brain tissue and cerebral perfusion pressure. The aim of this paper is to explore the value of blood lactate and lactate clearance in evaluating the survival rate and neurological outcome of patients with craniocerebral trauma. Methods The clinical data of 497 craniocerebral trauma patients admitted to our hospital from September 2017 to July 2018 were collected and retrospectively analyzed. Patients were divided into groups with different 6 h lactate clearance rates and admission lactate levels, and the differences in mortality and outcome of neurological function in each group were compared. Results The serum admission lactate levels、serum lactate levels at 6 hours, 28-day mortality and 28-day poor nerve function prognosis rate of patients with different 6h lactate clearance rates were statistically significant differences(P < 0. 05). The efficacy of 6h lactic acid to predict the mortality rate of patients was better than that of admission lactic acid and 6h lactate clearance rate (Z=3.71、Z=3.95,P<0.05). However, in predicting the neurological function of patients, the lactate clearance rate is not better than blood lactate level at any time(Z=1.30,Z=0.81,P>0.05). Conclusion 6h lactic acid has the best ability to judge the mortality of patients while lactic acid clearance rate is not better than the blood lactate level at any time in predicting the neurological function of patients.

ABSTRACT

OBJECTIVE: To observe the effect of liver-soothing and mental-activity-regulating (LSMAR) needling on behavior reactions and contents of serum calcitonin gene-related peptide (CGRP), substance P (SP), interleukin-1 β (IL-1 β) and tumor necrosis factor-α (TNF-α) in migraine rats, so as to explore its mechanism underlying relief of migraine. METHODS: Thirty-two male Wistar rats were randomly divided into control, model, LSMAR needling and conventional needling groups (n=8 rats in each). The migraine model was established by hypodermic injection of glyceryl trinitrate (5 mg/kg) at the napex. Acupuncture preconditioning was conducted once daily for 8 days before modeling. Acupuncture needles were inserted into "Baihui" (GV 20), and bilateral "Fengchi" (GB 20), "Neiguan" (PC 6) and "Taichong" (LR 3), manipulated for a while and retained for 30 min. The rats' behavioral changes (times of head scratching, tail-biting, cage-crawling, and to- and fro-movement in 30 min) were scored (one symptom = one point) before modeling, after modeling, and after intervention. The concentrations of CGRP, SP, IL-1 β, TNF-α in serum were assayed by enzyme-linked immunosorbent assay (ELISA). RESULTS: After modeling, the behavioral scores were significantly increased in the migraine model rats relevant to the control group (P<0.05). Whereas after the treatment, the behavior scores were considerably decreased during 60-90 min and 120-150 min of the measuring period in both LSMAR and conventional needling groups compared with the model group (P<0.05). The concentrations of CGRP, SP, IL-1 β and TNF-α were significantly higher in the model group than in the control group (P<0.05), and notably lower in both LSMAR and conventional needling groups than in the model group (P<0.05). The therapeutic effect of LSMAR was markedly superior to that of conventional needling in down-regulating the concentrations of CGRP, SP, IL-1 β and TNF-α (P<0.05). CONCLUSION: Acupuncture preconditioning can effectively relieve pain in migraine rats possibly by decreasing the concentrations of CGRP, SP, IL-1 β and TNF-α in the peripheral blood, and the therapeutic effect of LSMAR is evidently superior to that of conventional needling.

ABSTRACT

OBJECTIVE: To observe the effect of liver-soothing and mental-activity-regulating (LSMAR) needling on the expression of receptor activity-modifying protein 1 (RAMP 1, receptor of calcitonin gene-related peptide), 5-hydroxytryptamine 1 D receptor(5-HT 1 DR) in the spinal trigeminal nucleus (STN) and midbrain in migraine rats, so as to explore its underlying mechanism in relieving migraine. METHODS: A total of 40 male Wistar rats were randomly divided into control, model, LSMAR and conventional needling groups (n=10 rats in each). The migraine model was established by subcutaneous injection of nitroglycerin at the posterior neck. LSMAR was applied to "Baihui" (GV 20), bilateral "Fengchi" (GB 20), "Neiguan" (PC 6) and "Taichong" (LR 3) in the LSMAR group and conventional needling was applied to "Baihui" (GV 20) and bilateral "Fengchi" (GB 20) in the conventional acupuncture group for 30 min, once a day for 8 days before modeling. The expression levels of RAMP 1 and 5-HT 1 DR proteins and mRNAs in the STN and mesencephalon were detected by real-time fluorescent quantitative PCR and Western blot, separately. RESULTS: Compared with the control group, the expression levels of RAMP 1 protein and mRNA in STN and mesencephalon were significantly increased (P<0.05) and those of 5-HT 1 DR protein and mRNA considerably decreased (P<0.05) in the model group. After the acupuncture treatment, the increased levels of RAMP 1 protein and mRNA and the decreased levels of 5-HT 1 DR protein and mRNA in the STN and midbrain were obviously reversed in the LSMAR and conventional needling groups relevant to the model group (P<0.05). The effect of LSMAR needling was significantly superior to that of conventional needling in down-regulating the expression levels of RAMP 1 mRNA and protein in the STN and mesencephalon (P<0.05) and in up-regulating the expression levels of 5-HT 1 DR mRNA and protein in the two brain regions (P<0.05). CONCLUSION: Manual acupuncture stimulation of GV 20, GB 20, etc. can inhibit the expression of RAMP 1 protein and mRNA in the STN and midbrain, and up-regulate the expression of 5-HT 1 DR in the two brain regions of migraine rats, which may be related to its effect in relieving migraine.

ABSTRACT

OBJECTIVE: To explore standardized pharmaceutical care service mode from establishment of process for pregnancy combined with hypothyroidism or hyperthyroidism. METHODS: According to evidence-based medicine, relevant regulations and clinical practice, the pharmaceutical care process was established and tried out based on the clinical pharmacists' daily work. We used methods of pharmaceutical care classification and standard record forms to carry out the systematic, real-time and continuous medical supervision work for patients. RESULTS: Pharmaceutical care was performed on forty-two patients with hypothyroidism or hyperthyroidism in accordance with this procedure. Clinical pharmacists participated in the optimization of drug treatment regimens, intervened with irrational use of drugs, and advised on drug adverse reactions. CONCLUSION: The practice of pharmaceutical care process is beneficial for clinical pharmacists to carry out pharmaceutical service in depth and ensure the safety of drug use. Standardization can promote this procedure in the industry field, as well as promote the improvement and homogenization of professional skill level and pharmacy service ability of clinical pharmacists in gynecology and obstetrics.

ABSTRACT

The study was aimed to establish a liquid chromatography-tandem mass spectrometric method for the determination of the duloxetine concentration in rat plasma, and compare the pharmacokinetics in normal and diabetes mellitus rat models. Diazepam was used as an internal standard. The separation was achieved on a Waters Xterra® RP18 column (100 mm × 4.6 mm, 3.5 μm) with a mobile phase consisting of methanol -0.3% formic acid containing 5 mmol·L-1 ammonium acetate (75:25) at the flow rate of 0.6 mL·min-1. Electrospray ionization source was applied and operated in the positive multiple reaction monitoring mode. A good linearity of duloxetine was obtained in the concentration range of 10-5 000 ng·mL-1. The rat models of diabetes mellitus were established by intraperitoneal injection of streptozotocin. The same dose of duloxetine (40 mg·kg-1) was given by intragastric administration to the normal and diabetic rats. Blood samples were collected from the orbital venous plexus to determinate duloxetine concentration in the plasma. The pharmacokinetic parameters were calculated by DAS software. Statistical analysis was performed by SPSS software. The major pharma-cokinetic parameters of diabetes group were as follows: Cmax was 1 185 ± 190.0 ng·mL-1; AUC0-∞ was 8 398 ± 1 835 ng·mL-1·h; tmax was 1.6 ± 0.4 h; t1/2z was 3.6 ± 0.9 h. The major pharmacokinetic parameters of normal group were as follows: Cmax was 368.1 ± 40.7 ng·mL-1; AUC0-∞ was 4145 ± 640.1 ng·mL-1·h; tmax was 1.6 ± 0.3 h; t1/2z was 4.1 ± 0.8 h. The results of pharmacokinetic experiments suggest that the exposure amount of duloxetine in diabetic rats is twice higher than that in normal rats.
