Objective To study the effect of Zusanli and Guanyuan electroacupuncture ( EA) on inflammatory reaction in patients with sepsis. Methods A prospective and randomized trial was carried out in 58 sepsis patients, and the patients were randomly divided into EA group and control group. Patients in both groups were given conventional western medicine treatment, and EA group received EA at acupoints of Zusanli and Guanyuan additionally. The hospitalization time in intensive care unit ( ICU) of the two groups was compared. The changes of serum lactic acid (LA) level and inflammatory indexes including white blood cell and neutrophil count, C- reactive protein (CRP), erythrocyte sedimentation rate (ESR) and procalcitonin (PCT) of the two groups were observed before and after treatment. Results The hospitalization time in ICU of EA group was less than that of the control group, and the difference was statistically significant ( P<0.05) . On the seventh day after treatment, the serum LA level of EA group was significantly lower than that of the control group ( P<0.05) . Inflammatory indexes of EA group were decreased after treatment compared with those before treatment ( P<0.05) , and on seventh day after treatment, the inflammatory indexes of EA group were significantly lower than those of the control group ( P<0.05) . Conclusion EA at acupoints of Zusanli and Guanyuan is effective for the treatment of sepsis through reducing the inflammatory reaction of sepsis patients.

Objective To evaluate the value of cholangiography for early diagnosis of ischemic-type biliary lasions(ITBL) after liver transplantation. Methods Two hundred and fifty-three patients with liver transplantaion between Jan 2004 and Oct 2006 were recruited. Initial cholangiography was compared with terminal cholangiography to evaluate the value of initial cholangiography of ITBL. The t test, Chi-square test, sum rank test were used for statistics. Results Based on initial cholangiography, 189 patients were diagnosed with normal appearance, while 64 patients were diagnosed with abnormal appearance. The abnormal initial cholangiography appearances included poor filling in 33 patients and irregularity in 31 patients. Based on terminal cholangiogruphy, 199 patients were diagnosed with normal appearance and 54 patients with ITBL In patients with abnormal initial cholangiography, ITBL was occurred in 39 of 64 patients including 10 of 33 poor frlling patients and 29 of 31 irregularity patients. In patients with normal initial appearance, ITBL was only occurred in 15 of 189 patients. The abnormal initial cholangiography was associated with ITBL significantly (X2 = 79.999, P = 0.000, r = 0.490). Initial cholangiography had an overall sensitivity of 72.22%, and specificity of 87.44%, with positive and negative predictive values of 60.94% and 92.06%, respectively. The abnormal initial cholangiogruphy was a risk factor of ITBL by logistic regression analyses(OR=15.193, P=0.000). Conclusion The abnormal initial cholangiography is associated with ITBL Initial cholangiography, especially minimal irregular of intrabepatic biliary tract, is a sensitive and specific method for the detection of ITBL after liver transplantation.

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.

OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.
METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.
RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).
CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.
