Objective To explore the effect of Shenling Baizhu Powder and moxibustion on serum brain-gut peptide in patients with diarrhea predominant irritable bowel syndrome (D-IBS). Methods Sixty D-IBS cases were randomly divided into two groups, 30 cases in the treatment group were given Shenling Baizhu Powder and moxibustion therapy, and 30 patients in the control group were given loperamide hydrochloride capsule. Treatment for the two groups lasted for 4 weeks. Clinical symptoms and serum brain gut peptide (5-HT, VIP and SP) levels of two groups were observed before and after treatment, clinical efficacy were evaluated. Results Markedly effective rate of the treatment group was 66.7% (20/30), better than 33.3% (10/30) in the control group (P<0.05). After treatment, clinical symptom scores of the treatment group decreased significantly (P<0.01), while only diarrhea and abdominal pain improved in the control group (P<0.01), with statistical significance (P<0.01). After treatment, serum 5-HT, VIP, and SP of the treatment group were decreased (P<0.01), while these indexes of the control group did not change significantly (P>0.05), with statistical significance (P<0.01). Conclusion Clinical efficacy of Shenling Baizhu Powder and moxibustion in treating D-IBS is better than that of loperamide hydrochloride capsule, and can significantly improve clinical symptoms and regulate serum brain-gut peptides levels.

Objective To investigate the clinical study of sarcoside combined with tamsulosin in the treatment of type Ⅲ prostatitis. Methods 84 patients with type Ⅲ prostatitis who were treated and diagnosed in Jishuitan Hospital from November 2015 to December 2016 were randomly divided into experimental group and control group according to the time of hospitalization, 42 cases in each group. The control group was treated with tamsulosin hydrochloride sustained-release capsules, and the experimental group was treated with the addition of the new drug. The maximum urinary flow rate and mean urinary flow before and after treatment were recorded, compared and analyzed before and after treatment. Results The maximum urinary flow rate and mean urinary flow rate were increased in both groups after treatment, and there was significant difference between the two groups (P<0.05). The data of the maximum urinary flow rate and the mean urinary flow rate in the experimental group were significantly better than those in the control group. The data of the two groups were statistically significant (P<0.05). In addition, the experimental group after treatment of prostate symptom score was significantly better than the control group score, the two groups of data were significantly different, the data were statistically significant (P<0.05). In addition, the total effective rate of the experimental group was significantly higher than the control group(80.95%vs. 73.81%). The data were statistically significant (P<0.05). Conclusion The clinical efficacy of sorbenaside combined with tamsulosin in the treatment of type Ⅲ prostatitis is better than that of the original treatment. The treatment can improve the patient's urination and prostate symptoms and improve the patient's comfort.

OBJECTIVETo analyze the electrical activity property changes in nucleus accumbens (NAc) of heroin-induced conditioned place preference (CPP) rats during different stages of heroin dependence and to explore NAc's roles in the formation of drug dependence.

METHODSRecording electrodes were bilaterally embedded into the NAcs of rats with the aid of stereotaxic apparatus, followed by establishment of heroin-dependent rat model. The NAc electrical activity during 3 different stages of heroin dependence, including heroin pre-exposure, immediate post-exposure and heroin withdrawal, were respectively recorded using EEG wireless telemetry techniques. The frequency distribution (ranging from 0.5 to 30 Hz) and the amplitude of NAc electrical activity were analyzed and measured.

RESULTSHeroin-dependent rat models were successfully established and their withdrawal symptoms were evident. All rats showed a conditioned place preference (CPP) for the white box after 5-10 days of heroin-exposure, and displayed a maximum withdrawal symptoms on 2d after heroin- withdrawal. During all statges of heroin-dependence, the NAc electrical activity contained the highest proportion of delta rhythm and the lowest proportion of alpha2 rhythm. The discharge frequence band was similar across different stages. There was a significantly increased ratio of low-frequency discharges (delta rhythm) and decreased ratio of high-frequency discharges (beta rhythm) in NAc of rats during the immediate post- heroin exposure stage when compared with that during pre-exposure and heroin withdrawal stages. During the withdrawal stage, the ratio of at rhythm was significantly lower than during pre- and post-heroin exposure stages (P < 0.01). Further, the mean discharge amplitude in NAcs during immediate post-exposure and withdrawal stages was significantly increased relative to pre-exposure stage. However, the mean discharge amplitude during heroin withdrawal stage was significantly lower than during immediate post-exposure stage.

CONCLUSIONThe electrical activity properties in rat NAcs showed a significant change during different stages of heroin-dependence, which suggested that neuronal activities in NAcs might contribute to the modulation of drug-dependence.

The objective of this study is to develop a sensitive and reliable high-performance liquid chromatography mass spectrometry (LC-MS) method for simultaneous determination of artemisinin, arteannuin B, artemisic acid, and scopoletin, and study the pharmacokinetics of the four constituents in mouse serum after oral administration of the four components to mice. The analytical column used was Agilent Zorbax SB-C18 (2.1 mm x 150 mm, 5 mm). The mobile phase was acetonitrile: 0.5% acetic acid (60: 40) and the flow rate was 0.3 mL x min(-1). The temperature of the column was 40.0 degrees C. In this condition, we established an analysis method to simultaneously determine the four components. A sensitive and specific liquid chromatography-mass spectrometric (LC-MS) method was developed and validated for the determination of artemisin in derivatives in mice plasma. The method we established has a linear range of 5-3 000 μg x L(-1) with a good sensitivity and specificity for all of the four components. This method is simple, rapid, accurate and suitable for the determination of the content of the four compounds.

AIM:To investigate the regulatory effects of phosphatylinositol 3-kinase/protein kinase B (PI3K/PKB) signaling pathway on the expression of osteopontin ( OPN) in transforming growth factor-β1 ( TGF-β1 )-induced hu-man hepatic stellate cells .METHODS:Human hepatic stellate cell line LX-2 was cultured in DMEM and stimulated by TGF-β1 at the final concentration of 2.5, 5, 10 and 20 μg/L for 24 h or at final concentration of 10 μg/L for 12 h, 24 h and 48 h.LX-2 cells were pretreated with wortmannin , a specific inhibitor of PI3K/PKB signaling pathway , at final con-centration of 0.1 μmol/L for 1 h, followed by incubation with TGF-β1 at final concentration of 10μg/L for 24 h.The cells were collected.The expression of OPN was detected by real-time PCR and Western blotting .RESULTS: In LX-2 cells, the expression of OPN was apparently elevated when incubated with TGF-β1 .With the increase in TGF-β1 concentration or the extension of incubation hours , the expression of OPN was increased gradually in a dose-and time-dependent manner with certain limits.LX-2 cells pretreated with wortmannin and incubated with TGF-β1 had a significant decrease in the OPN expression as compared with control group (P<0.01).CONCLUSION:The expression of OPN in TGF-β1-induced LX-2 cells is regulated by the PI3K/PKB signaling pathway.

Objective To investigate the awaken effect of naloxon on dexmedetomidine anesthetized mice and its mechanism. Methods Thirty Kunming mice of clean grade were randomly divided into 3 groups which included NAL group (Naloxon group), ATI group(Atipamezole group)and NS group (Normal Saline group). All groups were given dexme?detomidine 1 mg·kg-1 intraperitoneally. Naloxon 2 mg·kg-1, atipamezole 2 mg·kg-1 and normal saline 10 mL·kg-1 were ran?domly given intraperitoneally to the NAL, ATI and NS group respectively 90 minutes after dexmedetomidine administration. At timepoints prior to dexmedetomidine administration and 5, 15, 30, 60, 90, 95, 105, 120, 180 minutes after it, the sedative and analgesic effects besides recovery time (based on restore of righting reflex loss) were assessed. Results Sedation and analgesia effects became apparent within 5 minutes, and peaked at approximately 60 minutes then spontaneously recovered at 180 minutes after injection of dexmedetomidine. The sedative and analgesic effects were reduced in both ATI and NAL groups. Compared with ATI group, the sedation scores were higher at 95, 105 and 120 minutes after dexmedetomidine admin?istration than those in NAL group (P<0.05) but the scores were not statistically significant at 180 minutes between these two groups. Compared with NS group, the sedation scores were lower at time points of 95, 105, 120 and 180 minutes than those in NAL group (P>0.05). The analgesic scores were not statistically significant at time points of 95, 105, 120 and 180 min?utes between NAL group and ATI group, but they were lower in NAL group compared with NS group at timepoints of 95, 105 and 120 minutes (P>0.05). The recovery time in ATI and NAL group were shorter than that in NS group (F=1 793.368, P<0.05), but it showed no statistical difference between ATI group and NAL group (P>0.05). Conclusion Naloxone had a certain awaken effect on dexmedetomidine anesthetized mice.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.

Objective To study the organ damage in patients with systemic lupus erythematosus (SLE) and its significance in prognosis. Methods The SLE damage index (SDI) was used to evaluate 121 female and 15 male patients. Results Among these patients, the lowest and the highest SDI was 0 or 9, separately (average: 1.79 ? 2.22). Most damaged organ was renal (39.0%), followed by muscle/skeletal system (19.9%) and cardiovascular system (18.4%). There was statistically significant difference of SDI in different groups of prognosis, life condition or disease duration ( 10 years). However, there was no significant difference of SDI in different sex groups. The correlation analysis revealed that the age at onset or diagnosis was not related to SDI. Conclusion SDI is effective in evaluating the organ damage in predicting prognosis of SLE patients.
