Textbook evaluation is of great significance in teaching studies and activities. By taking the establishment of evaluation index system forExperimental Acupuncture-moxibustion Science as an example, this article discussed the process and method of adopting the analytic hierarchy process for textbook evaluation: 3 levels, 4 dimensions, and 20 evaluation indexes were developed for the evaluation ofExperimental Acupuncture-moxibustion Science textbook, and each component of the indexes was assigned weight, based on which, a scale was established and preliminarily evaluated, in order to provide reference for the evaluation of the textbooks of traditional Chinese medicine.

OBJECTIVETo study the clinical effects of the Chinese drug Yimusake, used alone or in combination with trazodone hydrochloride, on primary premature ejaculation (PE).

METHODSSixty-eight primary PE patients were randomized to a control (n=32) and an experimental group (n=36), the former treated with Yimusake 1 tablet (50 mg) pre day, and the latter with 1 tablet of trazodone hydrochloride (50 mg) pre day in addition, both given orally after supper and for 4 weeks, followed by observation of the therapeutic effects.

RESULTSEighteen cases (56.25%) responded in the control and 25 (69.44% ) in the experimental group, with statistically significant difference between the two groups (P<0.05).

CONCLUSIONYimusake combined with trazodone hydrochloride is highly efficacious for primary PE.

Objective To explore the influence of accompany behavior on psychological health of neurosis patients'families.Methods 93 neurosis patients'families were divided into two groups according to whether they will accompany patients in hospital or not.The patients'families were investigated with SCL-90 when the patients were admitted and after 4 weeks admission,the psychological status were:compared between groups.Results The factor scores for sensitiveness of interpersonal relationship,hostility,phobophobia in both groups showed no difference compared with noFnl,while others were higher.when the patients were admitted At the same time,there Was no significant difference between groups.However,after 4 weeks admission,the factor scores of the subjects were no difference in experiment group compared with those when patients were admitted, whereas those in control group were lower and show significantly different.There were also difference between two groups after 4 weeks admission.Conclusions The psychological health of neurosis patients'family is abnormal,which is also aggravated by accompanying behavior,therefore we should guide the family to care for patients in right way.

OBJECTIVETo investigate the role of multidrug resistant protein 2 (MRP2) and glutathione (GSH) cotransport system in hepatic arsenic metabolism in rats.

METHODSThirty healthy Wistar rats were divided randomizedly into five groups. The first group was the control group and the rats in this group were administered with normal saline. In the second, third and fourth group the rats were administered with 4, 10 and 20 mg As(+)3/kg BW of sodium arsenite respectively every other day for two weeks. The fifth group was the benzene-soluble organics (BSO) intervention group and in this group the rats were administered with 2 mmol/kg BW BSO intraperitoneally every day three days before the end of the experiment. The other treatment was the same as in other groups. All rats were sacrificed two weeks after the treatments. Arsenic contents in bile, liver and blood were detected by atomic absorption spectroscopy (AAS), and the expression of MRP2 in the membrane of hepatocyte was determined by Western-blot analysis.

RESULTSThe level of total arsenic (including organic arsenic and inorganic arsenic) in bile, liver and blood in all three different dose groups was higher than those in the control groups (P < 0.05). Arsenic levels of bile and liver were increased with intragastric arsenic dose. Blood arsenic levels were not significantly different in three different dose groups. Expression of hepatic MRP2 was increased with intragastric arsenic concentration. A positive correlation between biliary arsenic concentration and MRP2 levels was found in liver (r = 0.986, P < 0.05). For the rats pretreated with BSO, the biliary arsenic was significantly higher than that in the control group but lower than that in the high dose group; the liver and blood arsenic was higher than that in the control group and in the high dose group. Expression of MRP2 pretreated with BSO was decreased.

CONCLUSIONSodium arsenite can induce expression of MRP2 and the up-regulation of MRP2 may play an important role in the bile secretion of arsenite and its metabolites. The function of MRP2 for transportation of arsenic and its metabolites is associated with the intracellular GSH level. BSO inhibits the synthesis of GSH, which weakens the function of the MRP2-GSH cotransport system and makes the liver arsenic increased.

OBJECTIVETo study the effect of necrostatin (Nec-1) on apoptosis induced by aluminum (Al), and approach the mechanism.

METHODSNeural cell death model was made by 4 mmol/L Al treated neuroblastoma cells (SH-SY5Y). Cell viabilities were detected at different concentrations of Al and/or Nec-1. Hoechst 33342/PI double staining was used to observe apoptosis and (or) necrosis that were quantified by flow cytometry using Annexin V/PI double staining. Apoptotic pathway was tested by activities of Caspase-3, Caspase-8 and Caspase-9. In addition, the expression of NF-kappa B and Cyt-c was measured by immunocytochemistry.

RESULTSCell viabilities were significantly decreased with the increasing concentrations of Al (P < 0.05), which could be significantly upregulated by 60 micromol/L Nec-1 (P < 0.05) and were correlated with the concentrations of Nec-1 (P < 0.05, P < 0.01). Apoptosis and necrosis were observed under fluorescent microscope and quantified by flow cytometry, which suggested an increasing trend of apoptotic and necrotic rates (P < 0.05, P < 0.01). Whereas, Nec-1 could not only decrease the necrotic rate but also apoptotic rate as well (P < 0.05, P < 0.01). Data of Nec-1 on caspases activities showed that Nec-1 could not affect Caspase-9 activity (P > 0.05) and Cty-c protein expression as well (P > 0.05). However, Nec-1 could reduce Caspase-8 activity significantly (P < 0.05, P < 0.01) and increase NF-kappa B protein expression (P < 0.05, P < 0.01) and finally decrease Caspase-3 activity (P < 0.05).

CONCLUSIONNec-1 could reduce cell apoptosis induced by Al, through Caspase-8 pathway, and up-regulate the expression of NF-kappa B protein.
