Objective To observe the inhibitory role of valproic acid (VPA) in hypertrophic cardiomycytes induced by angiotensin Ⅱ (Ang Ⅱ)in rats. Methods The cultured rat cardiomyocytes were divided randomly into control group, hypertrophic group and VPA group. They were treated with Ang Ⅱ to induce hypertrophy and then given with VPA. The morphologic changes of cardiomyocytes were observed under the contrast phase microscope and electron microscope. The mRNA levels ofβ-MHC were exmained by reverse transcriptase polymerase chain reaction (RT-PCR) method. The protein expression of C-FOS was exmanined by immunohistochemistry method. Results Stimulated by Ang Ⅱ, the cardiomyocytes were enlarged under the contrast phase microscope and the ultrastructure also changed. After stimulated by Ang Ⅱ, the mRNA level of β-MHC and the protein expression of C-FOS increased in the hypertrophic cardiocytes. Given by VPA, these data decreased accordingly. Conclusion VPA may inhibit the cardiomyocyte hypertrophy induced by angiotensin Ⅱ in some degree.

To study the influence of individualized medication guidance based on an Short Messaging Service( SMS) platform on the medication compliance in the patients with diabetes. Methods: Totally 100 cases of diabetic patients from the outpa-tient section were randomly divided into two groups using a number method with 50 ones in each, namely odd number was in the obser-vation group and even number was in the control group. The observation group was given pharmaceutical guidance based on the SMS technology platform by pharmacists, and the control group was given telephone follow-up once a week to understand the medical situa-tion. At the beginning of the study and after three-month treatment, the medication compliance in the two groups was evaluated, and the control situation of blood glucose was also compared. Results:There was no significant difference in the medication compliance be-tween the two groups at the beginning (P>0. 05). After the 3-month treatment, the blood glucose and medication compliance between the two group had statistical significance (P<0. 01). Conclusion:Based on a mobile phone short message technology platform, indi-vidualized clinical pharmaceutical guidance can significantly improve the medication compliance in diabetic patients.

This study analysed the tissue specific expression of critical genes involved in chlorogenic acid and luteolin biosynthesis, for exploiting the molecular mechanism of components biosynthesis in Lonicera confusa. Expression of PAL, 4CL, C4H, CHS, CHI, FNS and HQT gene families of chlorogenic acid and luteolin biosynthesis-related genes in buds and leaves of L. confusa were analyed by Real-time PCR. Expressions of PAL1, C4H1, 4CL1, CHS1, CHI3 and HQT2 in buds were lower than that in leaves, and expressions of PAL3, 4CL2, CHI2 and FNS2 in buds were higher than that in leaves. The results indicated that that PAL3 and 4CL2 may be associated with accumulation of chlorogenic acid, and the expression patterns of PAL1, CHS1, CHI3 and HQT2 in buds and leaves of L. confusa were different with L. japonica. This study provided some theoretical basis for the further research on genetic mechanism of active components differences in L. confusa and L. japonica.

Objective To investigate the changes in prevalence of nutritional risk and undemutrition in patients with head and neck cancer during radiotherapy.Methods In this longitudinal observational study,a convenience sampling method was used to recruit patients with head and neck cancer who were receiving radiotherapy in Beijing Cancer Hospital.Nutritional Risk Screening 2002 (NRS 2002) was applied to assess the prevalence of nutritional risk in the patients,and Patient-Generated Subjective Global Assessment (PG-SGA) and body composition test to determine the prevalence of malnutrition (undernutrition) before,during and after radiotherapy.Results 56 patients finished the three follow-up exams.Along with the progress of radiotherapy,the scores of NRS 2002 increased gradually (1.64±1.09 vs.2.30 ±1.06 vs.3.14 ±1.07,x2 =46.639,P＜0.001),and the prevalence of nutritional risk also increased gradually (21.43％ vs.37.50％ vs.71.43％,x2 =29.700,P ＜0.001);the total scores of PG-SGA [1 (1-13) vs.6 (1-15) vs.12 (1-18),x2 =63.206,P＜0.001] and dimensions of weight [0 (0-4) vs.1 (0-4) vs.3 (0-6),x2 =40.798,P＜0.001],intake [0 (0-2) vs.1 (0-2) vs.2 (0-4),x2=64.707,P＜0.001] and symptoms [0 (0-7) vs.2 (0-10) vs.6 (0-11),x2 =61.562,P ＜ 0.001] all increased gradually with statistical significance.The prevalence of malnutrition in different stage of radiotherapy were significantly different (x2 =64.999,P ＜ 0.001).The body composition analysis in 40 patients showed that all the indicators of body composition decreased significantly along with the progress of radiotherapy.There was a great loss in patients' body weight during radiotherapy,especially the fat-free mass.Conclusions The prevalence of nutritional risk and undernutrition may increase in patients with head and neck cancer during radiotherapy.Lean body mass accounted for most of the weight loss.We should pay more attention to those patients' nutritional status during radiotherapy.

The modern statistical and data mining technology is used to analyze the law of the acupoint selection in the treatment of insomnia with acupuncture and moxibustion. The clinical literature on the treatment of insomnia with acupuncture and moxibustion in recent 10 years is collected from China National Knowledge Infrastructure (CNKI). Excel software is applied to establish the database of acupuncture prescriptions for insomnia so as to conduct the descriptive analysis, association rule analysis and clustering analysis on the data. In the treatment of insomnia with acupuncture and moxibustion, Shenmen (HT 7) is of the highest frequency and most acupoints were selected from the Governor Vessel. The commonly used acupoints are located on the head, face, neck and nape region. The combination of the local acupoints with the distal ones is predominated. The crossing points among the specific points present the advantage in the treatment. The association: rule analysis indicates the highest, correlation among Taixi (KI 3), Sishencong (EX-HN 1) and Shenmen (HT 7). The clustering analysis results in 6 effective clusters and 10 pairs of key points and summarizes the common law of the acupoint combination for insomnia. All of these provide the reference to the treatment of insomnia with acupuncture and moxibustion.
