Objective:To investigate the effects of acupoint massage on cognitive function and sleep quality in elderly patients with hypertension. Methods:A total of 68 elderly patients with hypertension were enrolled, and their ages were all over 60 years old. They were divided into a control group and a treatment group by simple random method, with 34 cases in each group. Patients in the control group were treated by routine psychological health guidance and sleep knowledge education, while patients in the treatment group were treated by acupoint massage on the base of the interventions given to the control group. Both of their treatment courses were 3 months. Pittsburgh sleep quality index (PSQI) scores and mini-mental state examination (MMSE) scores before and after treatment were recorded and compared. Results:Two groups’ PSQI scores before treatment had no significant difference (P>0.05). After 3 months of treatment, their PSQI scores were statistically different (P<0.05). There was also no between-group statistical difference in MMSE score before treatment (P>0.05), but there was a significant difference after treatment (P<0.05). Conclusion:Acupoint massage for elderly patients with primary hypertension can improve their sleep quality and enhance their cognitive function, thus it is worthy of being applied in clinical nursing work.

We identified and characterized the full-length genome of a GI.8 norovirus strain CHN/Huzhou/N10 isolated in an outbreak in Huzhou,China.The full-length genome of CHN/Huzhou/N10 was amplified using five pairs of primers which were designed according to the full-length GI norovirus genome sequences published in GenBank database.Multiple alignments were performed using DNAStar,the phylogenetic relationship of CHN/Huzhou/N10 and the representative NoV (Norovirus) strains from each genogroup were assessed using the software MEGA version 6.0.The viral genome of CHN/Huzhou/N10 was 7 740 nucleotides in length,which was consist of three ORFs spanning 5-5 404 nt (ORF1),5 388-7 019 nt(ORF2),and 7 019-7 660 nt (ORF3),respectively.Phylogenetic analysis based on polymerase and capsid sequences VP1 and VP2 region indicated that CHN/Huzhou/N10 belonged to GI.8 genotype.The amino acid sequence analysis of the VP1 region showed that CHN/Huzhou/N10 had 16 mutations compared with the representative strain Boxer/2001/US,12 of these variations were located in the P2 subregion.Moreover,a single amino acid change (T347S) occurred at histo-blood group antigen (HBGA) binding site Ⅱ and another single amino acid change (T397E) occurred at HBGA binding site Ⅲ.In this study,the first full genome of norovirus GI.8 isolated in Huzhou,China was extensively characterized.The data would be helpful not only for the epidemiology study,but also for the diagnostic tool development and effective vaccine design in the future.

Purpose:To evaluate the physical dose distributions and tolerance in locally recurrent nasopharyngeal carcinoma treated with intensity modulated radiation therapy (IMRT).Methods:From June 1999 to August 2000, 10 patients with locally recurrent nasopharyngeal carcinoma proven by histology, without neck lymphoid node recurrence and distant metastasis, were treated by IMRT. The interval from the time of initial radiotherapy to recurrence ranged from 14—50(median 25) months. The initial radiotherapy in all patients were treated with external radiotherapy alone to a median dose of 69Gy/35fractions/52days. IMRT method was performed by means of the MIMiC collimator and inverse treatment planning system (NOMOS company, USA). The prescribed dose of re radiotherapy to target volume was 57Gy/19fractions/4weeks.Results:All patients, except for some patients with mild weight loss and reaction in the oral cavity during radiotherapy, tolerated this IMRT well. IMRT achieved the better immediate responses in 10 patients with complete response in 6 cases and partial response in 4 cases. Recurrence was found in two patients, lung distant metastasis in one patient. The median survival in the 10 patients was 14 months. The median planning target volume (PTV) was 95.8(60—134) cm 3. The dose distributions in the PTV were as follows: median average dose 59.65?2.47Gy, median homogeneity index (HI): 1.18(?0.06); median dose to 95% PTV ≥ 53.2 (?1.36)Gy. The median dose to the organs at risk (OAR) were as follows: spinal cord 9.46?5.23Gy; brain stem 20.24?3.55Gy; left parotid gland 18.53?5.30Gy, right parotid gland 19.68?6.21Gy; left lens 2.11?0.65Gy, right lens 2.94?0.57Gy;Chiasm12.34Gy; left optical nerve13.14 Gy, right optical nerve17.65 Gy.Conclusions:Better dose distributions treated with IMRT was achieved in the patients with locally recurrent nasopharyngeal carcinoma and the patients tolerated this radiotherapy well.

In the two groups, treatment of the 65 patients was completed smoothly as planned, and no one had serious complications, such as pancreatic leakage, skin burns, viscera perforation and radioactive enteritis. Conclusion Compound Kushen Injection combined with gamma knife can treat locally advanced pancreatic carcinoma safely and efficiently, which can improve patients’ life quality, especially in cancer pain control.

Objective To investigate the effect of Shensong Yangxin capsule on cardiac remodelling of myocardial infarction mouse model and the possible molecular mechanisms. Methods Adult male C57BL/6J mice were divided into sham operation group(n=10), model control group(n=20)and Shensong Yangxin group(n=20)according to random number table. Left anterior descending branch of coronary artery was ligated to establish myocardic infarction model in the model control group and Shensong Yangxin group. From the 2nd day after the surgery, Shensong Yangxin ( 400 mg . kg-1 ) was intragastrically administered, and the death rate of the mice was observed.Four weeks after the surgery, echocardiography was used to measure the cardiac function;myocardiac infarction area was detected by pathological staining;the expression levels of cardiac remodelling markers and extracellular matrix proteins were detected by RT-PCR. The possible molecular mechanisms were screened by Western blotting. Results As compared with the model control group, Shensong Yangxin significantly reduced the mortality after myocardial infarction in mice(P<0.05), as well as the myocardial infarct size(P<0.05).The mRNA expression levels of cardiac remodelling markers ANP, BNP, and β-MHC and the extracellular matrix proteins(collagenⅠ, collagen Ⅲ, CTGF, TGFβ) decreased significantly in the Shensong Yangxin group as compared with the model control group. Western blotting showed that Shensong Yangxin significantly decreased activation of smad3, and reduced expression level of smad4. Conclusion Shensong Yangxin attenuates cardiac remodelling after myocardial infarction and the mechanism may be related with blockage of smad signaling pathway.
