Aim To observe the effects of Rh2 on the hemodynamics and electrophysiological parameters in anesthetic rats. Methods The changes of hemodynamics and electrophysiological parameters in anesthetic rats were tested after administration with Rh2, such as SAP, DAP, MAP, LVSP, LVDP, LVEDP, ?dp/dt_ max,HR,RRP and ERP. Results Rh2 increased SAP,DAP,MAP,LVSP,?dp/dt_ max with the decrease of LVEDP. It had no distinct effects on HR, ECG, RRP and ERP. Conclusion Rh2 has the effects of increasing SAP,DAP and MAP in anesthetic rats and has no influence on HR, ECG and cardiac ventricle electrophysiological parameter, suggesting that the effect of increasing blood pressure could be related to the increases of peripheral resistance.

Background and purpose:The time from ifrst onset of symptoms or signs to a deifnitive diagnosis is deifned as diagnostic interval (DI). The relation of DI to other clinicopathological parameters andthe impact of DI on prognosis of patients with triple-negative breast cancer (TNBC) remain unclear.This article plans to make an intensive study of these questions.Methods:The clinical records of a series of 83 consecutively presenting unselected patients referred to the Shanghai Sixth People’s Hospital with diagnosed TNBC between September 2009 and September 2015 were retrospectively reviewed. Clinical and pathological factors included were investigated by univariate analysis using the Kaplan-Meier method, the factors associated with prognosis were further evaluated by multivariable analysis with Cox progression model.t-test and Kruskal-Wallis test were used to study the correlation between DI and other characters.Results:DI: stage T3>T1 (P=0.01), stageⅢ>Ⅱ (P=0.03) andⅠ (P=0.01). Compared with patients of DI≥3 months, the <3 months group had earlier age (P=0.028) and TNM stage (P=0.035). T stage, N stage, neoadjuvant chemotherapy, TNM stage and DI are inlfuencing factors of overall survival (OS). Age, T stage, N stage, TNM stage, menstrual status and neoadjuvant chemotherapy are inlfuencing factors of progression-free survival (PFS). TNM staging is an independent inlfuencing factor for OS and PFS.Conclusion:Patients with later disease stage were more likely to have a longer DI; The shorter DI, the earlier age and stage of disease; DI is the inlfuence factor of OS; TNM stage is an independent inlfuencing factor for OS and PFS.

Objective To investigate the expression of multidrug resistance protein such as multidrug resistance-associated protein 1 (MRP1),lung-resistance related protein (LRP), P-glycoprotein (Pgp),glutathione s-transferase (GST-π) and topoismerase Ⅱ (TOPO Ⅱ ) in hepatocellular carcinoma (HCC), which would be supplied for the clinical chemotherapy of HCC. Methods Twenty-six cases of HCC who underwent hepatectomy were enrolled and immunohistochemical (IHC) staining was carried out on all specimens for the detection of expression of MRP1,LRP,Pgp,GST-πand TOPO Ⅱ and the data was analyzed by image analysis system. Results The expression of five multidrug resistance protein in HCC tissue were significantly higher than those in adjacent tissue beyond cancer (P <0.05). The significant differences were found in the expression of Pgp,TOPO Ⅱ and GST-π between HCC tissue and distant metastasis (P < 0.05 ). The expression of the five multidrug resistance protein in poorly differentiated HCC tissue was higher than that in well-differentiated tissue,while the significant difference was only found in the expression of TOPO Ⅱ (P < 0.05 ). The significant association was not found between the expressions of five multidrug resistance protein in HCC tissue and the size of tumor,AFP, the portal vein tumor thrombus,hepatic cirrhosis and liver function. Conclusions Five multidrug resistance protein overexpression in various degrees in HCC tissue, which relates to some biological behavior of the cancer. Combined detection is of much benefit to the choice of the drug of chemotherapy and to the prediction of prognosis.

OBJECTIVE:
To evaluate the role of human calcium-activated chloride channel 1 (hCLCA1) and mucin MUC5AC in allergic rhinitis.
METHOD:
The expression of hCLCA1 and MUC5AC were determined by RT-PCR and immunohistochemical assay in nasal mucosa on 20 patients with allergic rhinitis and 7 normal persons.
RESULT:
The expression of hCLCA1mRNA in allergic rhinitis group was positive, whereas in normal control group was absent (P<0.01). The expression of MUC5AC mRNA and MUC5AC protein in the allergic rhinitis group were higher than that in the control, respectively (both P<0.01). The increased expression of hCLCA1mRNA in allergic rhinitis group were well correlated with the expression of MUC5ACmRNA and MUC5AC protein and the correlation coefficients were 0.752 and 0.694(both P<0.05).
CONCLUSION
Upregulation of hCLCA1 mRNA expression may play a pivotal role in mucus overproduction in allergic rhinitis group. The inhibition of HCLCA1 expression may provide a new strategy for the treatment of allergic rhinitis.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on perioperative anxiety and postoperative pain in living kidney donors (LKDs).Methods:Seventy-two American Society of Anesthesiologists physical status Ⅰ or Ⅱ LKDs, aged 18-64 yr, with body mass index of 18-28 kg/m 2, undergoing living kidney transplantation, were selected, and divided into 2 groups ( n=36 each) using a random number table method: TEAS group (group T) and sham stimulation group (group S). In group T, TEAS was performed on the forenoon at 1 day before surgery (T 0), at 30 min before anesthesia induction on the morning of the operation day (T 1) and on the forenoon at 1 day after surgery (T 2) at bilateral Neiguan, Taichong and Yintang with a frequency 2-100 Hz, disperse-dense waves and current intensity 6-15 mA, and each TEAS lasted for 30 min.Only electrode patches were applied at the same acupoint and at the same time point, but no stimulation was applied in group S. In T and S groups, brachial venous blood samples were collected before each stimulation for measurement of the plasma 5-hydroxytryptamine (5-HT) concentration.The Hospital Anxiety Depression Scale-Anxiety subscale (HADS-A) scores at T 0, T 1, T 2, on day 3 after surgery (T 3) and before discharge (T 4) in the 2 groups were recorded.The consumption of anesthetics during operation, laryngeal mask airway removal time, requirement for rescue analgesia within 72 h after surgery and the development of postoperative complications were recorded.The LKDs were followed up by telephone at 3 months after surgery (T 5) to record the scores of HADS-A and Leeds Assessment of Neuropathic Symptoms and Sign (LANSS) scale. Results:Compared to group S, the incidence of anxiety was significantly decreased T 1, T 2 and T 3, the incidence of rescue analgesia within 72 h after surgery was decreased, plasma concentration of 5-HT was increased at T 1 and T 2, the incidence of postoperative nausea and vomiting was decreased, and the time to first flatus was shortened in group T ( P<0.05). There was no significant difference in the consumption of anesthetics during operation, laryngeal mask airway removal time, and the incidence of anxiety and neuropathic pain within 3 months after surgery between the 2 groups ( P>0.05). Conclusion:TEAS can relieve early preoperative and postoperative anxiety and alleviate postoperative pain in LKDs.
