OBJECTIVE: To investigate the effect of Yinlai Decoction (YD) on the microstructure of colon, and activity of D-lactic acid (DLA) and diamine oxidase (DAO) in serum of pneumonia mice model fed with high-calorie and high-protein diet (HCD). METHODS: Sixty male Kunming mice were randomly divided into 6 groups by the random number table method: normal control, pneumonia, HCD, HCD with pneumonia (HCD-P), YD (229.2 mg/mL), and dexamethasone (15.63 mg/mL) groups, with 10 in each group. HCD mice were fed with 52% milk solution by gavage. Pneumonia mice was modeled with lipopolysaccharide inhalation and was fed by gavage with either the corresponding therapeutic drugs or saline water, twice daily, for 3 days. After hematoxylin-eosin staining, the changes in the colon structure were observed under light microscopy and transmission electron microscope, respectively. Enzyme-linked immunosorbent assay was used to detect the protein levels of DLA and DAO in the serum of mice. RESULTS: The colonic mucosal structure and ultrastructure of mice in the normal control group were clear and intact. The colonic mucosal goblet cells in the pneumonia group tended to increase, and the size of the microvilli varied. In the HCD-P group, the mucosal goblet cells showed a marked increase in size with increased secretory activity. Loose mucosal epithelial connections were also observed, as shown by widened intercellular gaps with short sparse microvilli. These pathological changes of intestinal mucosa were significantly reduced in mouse models with YD treatment, while there was no significant improvement after dexamethasone treatment. The serum DLA level was significantly higher in the pneumonia, HCD, and HCD-P groups as compared with the normal control group (P<0.05). Serum DLA was significantly lower in the YD group than HCD-P group (P<0.05). Moreover, serum DLA level significantly increased in the dexamethasone group as compared with the YD group (P<0.01). There was no statistical significance in the serum level of DAO among groups (P>0.05). CONCLUSIONS YD can protect function of intestinal mucosa by improving the tissue morphology of intestinal mucosa and maintaining integrity of cell connections and microvilli structure, thereby reducing permeability of intestinal mucosa to regulate the serum levels of DLA in mice.

OBJECTIVE: To verify the efficacy of transcutaneous electrical acupoint stimulation (TEAS) on catheter related bladder discomfort after ureteroscopic lithotripsy. METHODS: Sixty male patients with selective ureteroscopic lithotripsy under general anesthesia were randomly divided into a TEAS group (30 cases, one case dropped off) and a sham TEAS group (30 cases, 2 cases dropped off). Before anesthesia induction, the patients in the TEAS group were treated with TEAS at Guanyuan (CV 4), Zhongji (CV 3), Zusanli (ST 36) and Sanyinjiao (SP 6) for 30 min, with disperse-dense wave, frequency of 2 Hz/ 15 Hz and current intensity of 6 to 10 mA. The patients in the sham TEAS group were treated with the same TEAS device at the same acupoints, but no electrical stimulation was given. After 30 min, anesthesia induction started. The total dosages of propofol and remifentanil in the two groups were recorded, and the time of operation and anesthesia, the time of wake-up and the time of stay in postanesthesia care unit (PACU) were recorded. The postoperative recovery was evaluated 5 min (T) after wake-up, 1 h (T), 2 h (T) and 6 h (T) after the operation, including the severity of urinary tract irritation and visual analogue scale (VAS) score. The occurrence of adverse reactions was observed, such as nausea and vomiting, dizziness and headache. RESULTS: The dosage of remifentanil in the TEAS group was significantly lower than that in the sham TEAS group (<0.05); but the dosage of propofol had no significant difference between the two groups (>0.05). Compared with the sham TEAS group, the incidence of more-than-moderate urinary tract irritation symptoms in the TEAS group was reduced (<0.05), and the VAS scores 1 and 2 h after operation were reduced (<0.05). CONCLUSION The 30-min TEAS at Guanyuan (CV 4), Zhongji (CV 3), Zusanli (ST 36) and Sanyinjiao (SP 6) before anesthesia induction could significantly control the severity of postoperative urinary tract irritation in patients with ureteroscopic lithotripsy, reduce the dosage of anesthetic drugs and relieve postoperative pain.

The quality definition of traditional Chinese medicine (TCM) is a hot area in modern research of TCM. In recent years, the characteristics of one herb with multiple effects have been widely accepted and studied. The typical opposite-effect of herbs is considered as a special part of one herb with multiple effects, and was summarized in this paper. Sanqi was used as an example of opposite-effect herbs for developing the strategies and approaches on the Q-markers. The traditional opposite-effect should be studied by modern pharmacological research methods. The correlation of the chemical components with the opposite effects should be established in order to verify the material basis and evaluate the mechanism including targets and pathways. The unique characteristics of chemical components should be analyzed and defined. Finally, the Q-markers of the opposite effect herb will be confirmed. This paper provides a useful reference for the precise quality control of herbal opposite-effects.

Objective To evaluate the effect of SvO2-guided early goal directed fluid therapy on hemodynamic and oxygen dynamics in septic shock pig model. Methods Twelve Bama miniature pigs (male, 21-24 kg) were equally randomized into 2 groups, group C and group G. Septic shock was induced by intravenous infusion endotoxin. Group C received hemodynamic support aiming central venous pressure at 8 to 12 mmHg, urinary output 0.5 mL/kg per hour, and mean arterial pressure greater than 65 mmHg. Group G maintained SvO2 greater than 0.65 in addition to the above indicators. The interventions lasted 6 h and at T0-T8 (0, 60, 120, 180, 240, 300, 360, 420 and 480 min) recorded temperature, hemodynamic and oxygen dynamics indexes for each group, and recorded 6 hours for accumulated liquid volume, vascular active drug, and changes of urine. Results There were no significant differences in mean arterial blood pressure (MAP), heart rate (HR) and systemic vascular resistance index (SVRI) at each time point between group G and group C ( P>0.05). Values of CI and CVP were increased at T4-T8 in group G (P<0.05). Values of MPAP and PVRI were decreased at T8 in group G (P<0.05). Values of SvO2 were increased at T3-T8, O2ER were decreased at T3-T8 (P<0.05), DO2 were increased at T4-T8 (P<0.05), Lac were decreased at T5-T8, andΔp(CO2) was decreased at T8 in group G (P<0.05). There were no significant differences in values of VO2 at T1-T8 between two groups (P>0.05). The amount of intravenous infusion and urine volume were more and the amount of norepinephrine was less in animals of group G (P<0.05). The dosage of dobutamine was more in animals of group G, and which was not used in animals of group C. Conclusion SvO2 guided fluid therapy is more effective than conventional treatment to stabilize hemodynamics and oxygen kinetics, which is characterized by the increased cardiac output, increased oxygen supply, normal oxygen uptake rate and good tissue perfusion.

Objective To investigate the correlation between inflammatory cells, body temperature changes, and TCM syndromes of deep venous thrombosis (DVT) patients in acute and subacute phases. Methods The data of age, gender, body temperature, blood routine, venous ultrasonography, and four diagnostic information of 130 DVT patients in acute and subcute phases were collected and analyzed in a cross-sectional study. The correlation between inflammatory cells and the changes of body temperature and TCM syndromes were analyzed. Results Among 130 DVT patients, 37 patients had damp-heat syndrome, 64 patients had blood stasis and dampness syndrome, and 29 patients had qi stagnation syndrome. Neutrophils increased most obviously in blood stasis and dampness syndrome (P<0.05), which had close correlation with the skin redness (OR=1.287, 95%CI: 9.412-21.247). The mononuclear cells increased most obviously in the damp-heat syndrome, which has close correlation with nouhof (OR=7.364, 95%CI:1.189–45.603), high skin temperature (OR=6.683, 95%CI:1.791–24.938), skin tightness (OR=6.107, 95%CI:1.423–26.203) and weakness (OR=3.302, 95%CI: 1.002–9.169). The temperature rising was the most common in the damp-heat syndrome, and the increase of mononuclear cells was the most common one. Conclusion DVT is often accompanied with elevated levels of inflammatory cells and body temperature. Damp-heat syndrome has close correlation with body temperature and mononuclear cells increasing. Dampness and blood stasis syndrome and neutrophils are closely related.

BACKGROUNDGenetic mechanisms contribute to blood pressure regulation. This study investigated whether glutathione peroxidase (GPx-3) tag single nucleotide polymorphisms (SNPs) are associated with hypertension in the rural areas of Fuxin county, Liaoning province, China.

METHODSIndigenous Fuxin Han people participated, 523 unrelated hypertensives and 547 controls were recruited. All tag SNPs of GPx-3 gene were selected. We estimated SNP allele frequency in DNA pools with pyrosequencing.

RESULTSBefore Bonferroni correction, C allele frequency for rs8177417 was significantly higher in hypertensives than those in controls (23.4% vs. 19.3%, P = 0.014); T allele frequency for rs3828599 was significantly lower in hypertensives than those in controls (35.6% vs. 40.8%, P = 0.009). However, when a Bonferroni correction for multiple testing was applied, only the polymorphisms rs3828599 of GPx-3 gene was associated with hypertension (P = 0.045, OR: 0.833, 95%CI: 0.695 - 0.998).

CONCLUSIONThe polymorphism of rs3828599 of GPx-3 gene might be associated with hypertension in rural Han Chinese from Fuxin, Liaoning.

Objective To investigate the ultrastructural variation of the facial nerve of rabbit with different dosage of 125I seed brachytherapy. Methods Fifty-four big ear rabbits were divided into 3 groups randomly and given 40 Gy, 80 Gy, 120 Gy respectively. Radioactive seeds were implanted in one side of parotid gland, the other side was implanted with vacant shell as a control group. The facial nerves were obtained 2, 4, 6 months respectively after operation and the histological ultrastructural changes observed by electromicroscope. Results In the control group,epineurium was continuous, there was slight pitting edema under the epineurium, and axonal myelin was loose. In the test groups, there was slight pitting edema under the epineurium, and axonal myelin sheath was loose at 4th month. Macrophage and regenerated fibers were found in the 80 Gy group and myelin sheath lamellar separation, regeneration of nerve in the 120 Gy dosage. The myelin sheath lamellar was separated and axonal myelin loose in the test group at 6th month.Myelin sheath amellar separation and edema under the epineurium were found in the group of 80 Gy and 120 Gy. Conclusions The ultrastructure of the facial nerve is damaged by the dosage of 40 Gy, 80 Gy brachytherapy with 125I seeds. The higher dosage the nerve receives,the more serious the damage will be. Both of the epineurium and axonal myelin sheath are integral and continuous 6 months after operation with dosage of 120 Gy.
