Objective To study the expression of proliferating cell nuclear antigen (PCNA), CDK4 and P16 on rat hepatocellular carcinoma by millimeter wave radiation. Methods Fourty male Wistar rats were randomly divided into four groups. Group one to three were feeded by diethylnitrosamine (DEN). Group one was a tumor control group. In group two and three the liver was directly radiated by 35.8 GHz, 100 mW/cm 2 millimeter wave for 20 min, twice a week for 10 or 5 weeks. Group four was a normal control radiated group. Fourteen weeks later all rats were sacrificed to undergo serological test and immunohistochemical stain of liver. Results The serum levels of ? glutamyltransferase in group two and three were lower than that in group one. Adenocarcinoma was only existed in group one by histological examination of liver tissue. Other groups of DEN exposure only had basophilic and eosinophilic nodules. Liver tissue expression of PCNA and CDK4 in group two and three were significantly lower than in group one, but the expression of P16 in group two and three was higher than that in group one. Conclusions Radiation with millimeter wave can partially inhibit cell proliferation and suppress the DEN induced hepatocellular carcinoma in rats.

Objective To explore the characteristic and clinical value of Somatosensory Evoked Potential SEP and event?related potential P300 in patients with Juvenile Myoclonic Epilepsy (JME), trying to provide neuroelectrophysiological evidence for the pathogenesis, diagnosis and antiepileptic drug efficacy of this disease . Methods 28 patients with JME and 30 healthy controls were enrolled in the research. They were applied the SEP and P300 before and after one year treatment. Results (1) The amplitude of SEP in patients with JME was significantly higher than those in the control group(P=0.000), the abnormal rate was 75%(21/28), while the latency of SEP was no significant difference (P>0.05); The latency of P300 in patients with JME was significantly longer (P = 0.000), 2 out of 28 cases were poorly differentiated, 9 cases were longer (11/28, 39%), while the P300 amplitude was no significant difference(P=0.110). (2) After treatment, the amplitude of SEP was significantly lower (P<0.05), the latency of P300 was significantly shorter (P=0.001). (3) The amplitude of SEP had a positively linear relationship with the latency of P300 (r = 0.818, P = 0.000). Conclusions The SEP amplitude was significantly higher in patients with JME, often accompanied by a huge SEP, so SEP can provide electrophysiological evidence for the pathogenesis and diagnosis of this disease.And P300 may give a chance to find the subclinical cognitive abnormalities and to intervent it early. The SEP had a positively linear relationship with the P300, simultaneously dynamic monitoring the change of SEP amplitude and P300 latency may become an objective evaluation for the antiepileptic drug efficacy.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

OBJECTIVETo evaluate the efficacy of internal application of Qigui Mixture (QM) and external application of Qigui Huoxue Lotion (QHL) in treating type 2 diabetic peripheral neuropathy (DNP) patients of qi-yin deficiency complicated phlegm-dampness blocking collaterals syndrome (QYD-PDBCS), and to primarily discuss its mechanism.
METHODSTotally 62 DPN patients of QYD-PDBCS were randomly assigned to the treatment group (31 cases) and the control group (31 cases). All patients received routine comprehensive therapy. Patients in the control group took Mecobalamine Tablet, 500 microg each time, 3 times per day. Patients in the treatment group additionally took QM, 200 mL per day, twice daily. Besides, they had foot bath in QHL 10 - 15 min every evening for 3 months. The efficacy was assessed by Chinese medical symptom integrals and Toronto clinical scoring system (TCSS) before treatment, 2 and 3 months after treatment. The nerve conduction velocity was determined; the serum levels of total antioxidant capacity (T- AOC), malondialdehyde (MDA), and superoxide dismutase (SOD) were detected 2 and 3 months after treatment.
RESULTSThe total effective rates of Chinese medical symptom integrals and TCSS score were obviously higher in the treatment group than in the control group (P < 0.05). The nerve conduction velocity was significantly improved in the treatment group, when compared with before treatment (P < 0.01). There was statistical difference in the nerve conduction velocity difference of right median nerve motor branch, bilateral tibial nerve motor branches, bilateral common peroneal nerve motor branches, bilateral ulnar nerve sensory branches, and left tibial nerve sensory branch (P < 0.05). Compared with before treatment, serum levels of T-AOC and SOD significantly increased, and the level of MDA decreased significantly in the treatment group after 2 and 3 months of treatment (P < 0.01). But only the SOD level increased significantly in the control group (P < 0.01). There was no statistical difference in increased T-AOC level between the two groups after 2 months of treatment (P > 0.05), but there was statistical difference in increased SOD level and decreased MDA level (P < 0.05). There was statistical difference in increased T-AOC and SOD levels and decreased MDA level between the two groups after 3 months of treatment (P < 0.05). No adverse reaction occurred during the therapeutic course.
CONCLUSIONSThe internal application of QM and external application of QHL combined with Mecobalamine in treating DPN was safe and effective, with more significant efficacy than using Mecobalamine alone. Its mechanism might be associated with resistance to oxidative stress.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.
METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.
RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].
CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.
