The experiment was designed to study the mechanism of increasing efficiency of Ligustrum lucidum steamed with wine. Rats in vivo with gastrointestinal perfusion model were used. The contents of salidroside and specnuezhenide in the fluid of gastrointestinal perfusion of rats were measured by HPLC at different time points after dosing. Then the K(a) and absorption percentage were calculated. Specnuezhenide could be detected in the fluid of gastrointestinal perfusion of specnuezhenide. The K(a) of the specnuezhenide and salidroside in the fetal intestines are 0.055 3 and 0.144 2 h(-1) respectively and the total absorptivity are 24.46% and 60.14% respectively after 4 hours. The K(a) in the stomach are 5.70 and 8.26 h(-1) respectively and the total absorptivity are 34.21% and 47.23% respectively after 4 hours. The experiment proved that specnuezhenide can be metabolized into salidroside which is more beneficial for gastrointestinal absorption. The experiment proved that specnuezhenide can be metabolized into salidroside both in the rat's stomach and the fetal intestine and compared with the specnuezhenide salidroside is more conducive to gastrointestinal absorption. The results suggested that the increasing efficiency on liver and kidney of L. lucidum steamed with wine has business with the fact that Specnuezhe nide is more conducive to the body after it is changed into salidroside.

AIM: To investigate therapeutic efficiency of amniotic extraction on dry eye in rabbit model induced by topical benzalkonium chloride (BAC).
METHODS: Totally 26 rabbits (26 right eyes) with dry eye model were studied and divided into two groups:group A (control group with PBS eye drops, n = 13) and group B ( amniotic extraction group, n = 13). Another two rabbits were chosen as normal control. The SchirmerⅠ tests ( S Ⅰ t) and corneal fluorescein staining ( FL) were made, and the tear total protein content, amylase activity, lactoferrin, lysozyme contents, goblet cell density were performed in two groups before treatment and 1, 2, 4 and 8 wk after treatment.
RESULTS: There were significant differences in SIT, FL scores, lysozyme activity and goblet cell density among different groups at different time points (P<0. 05). But, there was no significant differences in SⅠt, FL scores, lysozyme activity and goblet cell density between two groups before treatment (P>0. 05). After 8wks' treatment with PBS, the mean differences of the group A showed great changes in SⅠt, lysozyme and goblet cell density compared with those before treatment ( P < 0. 05); but there was no significant differences in FL scores compared with those before treatment (P>0. 05). As for group B, 8wks after treatment, there were statistical changes in SⅠt, FL, lysozyme (P<0. 05); but there was no significant differences in goblet cell density compared with those before treatment ( P > 0. 05). It was evident that statistical differences were observed in S Ⅰ t, FL scores, lysozyme activity and goblet cell density between two groups at each time point (P<0. 05). However, there were no significant differences in total protein, lactoferrin, amylase activity at different time points (P>0. 05). Meanwhile there was no significant differences in total protein, lactoferrin, amylase activity between two groups before treatment ( P > 0. 05 ). But there were significant differences in total protein, lactoferrin, amylase activity between two groups after 4 and 8 wks'treatment (P<0. 05).
CONCLUSION: Amniotic extraction has significant therapeutic effect on the dry eye in rabbit model.

Objective To observe the effects of acupuncture in acupoints at different meridians on 5-HT, DA, NE in the peripheral serum of insomnia rats; To explore the mechanism of action of acupuncture for the treatment of insomnia. Methods Sixty SD rats were randomly divided into blank group, model group, Baihui+Shenmen group, Baihui+Sanyinjiao group, and Baihui+non-acupoint group, with 12 rats in each group. Injection of PCPA suspension of rats was used to establish insomnia model. Each acupuncture group received corresponding acupoints, 30 min each time, for 7 days. The levels of 5-HT, DA and NE in serum were measured by ELISA. Results Compared with the blank group, the levels of 5-HT, DA and NE in the model group were significantly higher than those in the blank group (P<0.01). Compared with the model group, the contents of DA and NE in the acupuncture groups were significantly lower than those in the model group (P<0.05, P<0.01), and the 5-HT in Baihui+Sanyinjiao group was significantly lower than those in the model group (P<0.05). Among all acupuncture groups, overall efficacy of Baihui+Shenmen group was better than Baihui+Sanyinjiao group and Baihui+non-acupoint group. Conclusion Acupuncture can improve sleep structure in rats may be related to serum monoamine neurotransmitters. Acupuncture in acupoints at different meridians may be one of the influencing factors of acupoint compatibility effects.

Objective To observe the effects of acupuncture treatment on the levels of HPA axis related hormones and acupoint compatibility in insomnia rats; To discuss the mechanism of action for acupuncture treatment. Methods Chlorophenylalanine suspension was under intraperitoneal injection to establish insomnia model rats. Sixty SD rats were randomly divided into blank group, model group, Baihui+Shenmen group, Baihui+Sanyinjiao group, Baihui+non-acupoint group, with 12 rats in each group. Each treatment group received acupuncture in relevant acupoints, 30 min each time, for 7 d. ELISA was used to measure the levels of CRH, ACTH and CORT. Results Compared with the model group, the levels of CRH, ACTH and CORT of the acupuncture groups decreased to some extent. In the three acupuncture groups, the efficacy of Baihui+Shenmen group was better than that of Baihui+Sanyinjiao group and Baihui+non-non-acupoint group. Conclusion Acupuncture treatment may calm and soothe the nerves to release the insomnia through regulating HPA axis related hormones. Acupuncture acupoints at different meridians may be one of the factors that cause the difference of acupoints compatibility effect.

OBJECTIVETo investigate the role of non-high density lipoprotein cholesterol (non-HDL-C) in the assessment of cardiovascular disease (CVD) risk factors such as hypertension, pre-diabetes and diabetes in obese children.

METHODSAccording to the presence of complications (hypertension, pre-diabetes and diabetes), 810 children with central obesity were divided into two groups: one group with complications (n=499) and one group without complications (n=311). One hundred and sixty-four age- and sex-matched children served as the control group. Logistic regression analysis and receiver operating characteristic (ROC) curves were used to analyze the detection of non-lipid CVD risk factors by seven lipid markers.

RESULTSThe prevalence rates of hypertension and pre-diabetes were significantly higher in obese children with high non-HDL-C concentrations (≥3.76 mmol/L). After adjusting for waist circumference Z-scores, the area under the ROC curve for non-HDL-C was 0.680 to detect non-lipid CVD risk factors, while the areas for low-density lipoprotein cholesterol, total cholesterol and apoprotein B were 0.659, 0.669 and 0.647 respectively.

CONCLUSIONSCompared with the other lipid markers, non-HDL-C is a better predictor for non-lipid CVD risk factors in obese children. Measurement of non-HDL-C concentations is recommended for obese children.

The study was aimed to investigate the immunophenotypic and cytogenetic features of chronic lymphocytic leukemia (CLL) in order to provide an evidence for diagnosis and therapy. Immunophenotypic analysis was performed by using a panel of monoclonal antibodies and three-color immunofluorescence staining methods of flow cytometry in 51 patients with CLL, and the cytogenetic features were analyzed by R-banding technique. The results indicated that among 51 CLL cases, the positive rate of CD19 and CD23 was 96.1%, followed by CD15 (94.1%), CD20 (82.4%) and CD22 (78.4%). The positive rate of CD38 was 23.5%. Forty-six patients expressed both CD5 and CD19. Seven main clonal chromosomal abnormalities were detected by conventional cytogenetics (CC) in eighteen cases (35.3%), with three cases of +12, two cases of 13q(-), other chromosomal abnormalities included +14, 6q(-), t (11; 14), t (14; 18) and t (2; 7). Expression of the antigens had no relationship with chromosomal abnormalities. It is concluded that typical CLL express CD5, CD19 and CD23, and the positive rate detected by CC in CLL is low. Immunophenotyping in combination with cytogenetic technique plays an important role in the diagnosis and prognosis of CLL.

To study the effect of Yinghua Pinggan granule (YHPG) against influenza A/H1N1 virus in vivo and on the immunologic function of infected mice. The intranasal influenza virus infection was adopted in ICR mouse to establish the influenza virus pneumonia model. At the 3rd and 7th day after the infection, the lung index and pathologic changes in lung tissues of mice were detected. Realtime PCR and flow cytometry were employed to observe the virus load in lung tissues and the levels of CD4+, CD8+, and CD4+/CD8+ in peripheral blood. The result showed that at the 3rd and 7th day after the infection, YHPG (15, 30 g x kg(-1)) can significant decrease in the lung index and virus load in lung tissues of mice infected with influenza virus, alleviate the pathologic changes in lung tissues, significantly increase the levels of CD4+ and CD4+/CD8+ ratio and reduce the levels of CD8+ in whole blood. This indicated that YHPG can inhibit the influenza virus replication, alleviate pulmonary damage and adjust the weak immunologic function of infected mice, with a certain therapeutic effect on mice infected by H1N1 virus in vivo.
