China Pharmacy 2005;0(13):-
OBJECTIVE: To seek approach for the protection of domestic pharmaceutical enterprises with immature creativity and to ensure drug accessibility. METHODS: An analysis was performed applying the theory of demand elasticity by comparing the attributes of health right and patent right etc based on TRIPS protocol and the related practice abroad. RESULTS & CONCLUSIONS: For a developing country, China should give top priority to the short-term urgent needs, such as to meet people's medication demands, followed by meeting the long-term demands, such as to encourage independent intellectual property rights. Hence, drug accessibility-related system in drug patent system should be evolved step by step.

Objective To show the international protocols for blood pressure monitoring based on a real example. Methods The assessment process of international protocol that can be released by Working Group on Blood Pressure Monitoring of European Society of Hypertension was evaluated. Results 33 participants were selected, which all indexes in evaluation stage one and stage two of the indicators were detected through. The 95% consistency interval in difference between tested device and reference monitor was 10.65~-12.67 mmHg for systolic BP and 13.68~-14.03 mmHg for diastolic BP, and there were 7.1% (7/99) and 6.1% (6/99) of valid points out of the 95% consistency interval. Conclusion The measured automatic blood pressure in the normal environment, measuring accuracy and the standard with the control of mercury -type sphygmomanometer is coincident, so it can be recommended for home application.

40/h) and non-severe group(n=15,AHI 5-40/h).Anthropometric measurements,fasting plasma glucose,insulin,blood fat,and CT quantitative measurement of abdominal adipose tissue were recorded. Results Insulin resistance index(HOMA-IR) in patients with OSAS was related to hypoxia independently of obesity variables.The severe group was characterized by more serious metabolic disorders and higher prevalence of metabolic syndrome than the non-severe group.OSAS was positively associated with an increased metabolic disorders risk for the severe group versus the non-severe group(OR=8.8).Using the receiver operating characteristic(ROC) curve analysis,waist circumference had the greatest areas under the ROC curves compared with body mass index and neck circumference.The results of multiple stepwise regression of lowest pulse oxygen saturation(LSpO2)during overnight sleep indicated that neck circumference followed by epworth sleepiness score(ESS) entered the equation(P

Objective To explore the clinical application of ultrasonography on tethered spinal cord syndrome (TCS).Methods Ultrasonic feature of 45 patients with TCS were analyzed retrospectively. Pre-and post-operative blood flow rates of cone were recorded by color doppler.Results Ultrasound was the same as computer tomography not only presented the image of anatomy and pathology of TCS,but also showed the lack of pulsatile motion of distal cord with TCS.Before the operation,blood flow rates of cone were( 0.047?0.012) m/s.After the operation,blood flow rates of cone were(0.158?0.029) m/s.There was significantly different(P

Objective To compare the clinical effects of electroacupuncture at antagonistic motor points and at acupoints on ankle varus post stroke. Methods 96 patients with ankle varus post stroke were randomly divided into treatment group (n=48) and control group (n=48). All the patients accepted Bobath approach. The treatment group accepted electroacupuncture at antagonistic motor points, while the control group at antagonistic acupoints. They were assessed with Holden functional ambulation category, modified Ashworth scale and dorsiflexion- eversion grade of ankle before and after 4 weeks of treatment. Results The ambulation, spasticity of ankle, and dorsiflexion-eversion of ankle improved in both groups after treatment (P<0.05), and improved more in the treatment group than in the control group (P<0.05). Conclusion Electroacupuncture at antagonistic motor points may release spasticity of ankle post stroke more effective than at acpoints

The paper is aimed to identify SNP in Sarcandra glabra and Chloranthus spicatus, and authenticate S. glabra from Ch. spicatus and the mixture by using PCR amplification of specific alleles. SNPs in the ITS sequences of S. glabra and Ch. spicatus were found by ClustulX 2. 1 program and Bioedit software. Primers for authentic S. glabra and Ch. spicatus was designed according to the SNP site, and ITS sequence universal primers plus to the authentic primer to construct a multi-PCR reaction system, and then optimized the PCR reaction system. Five hundred and eighty band special for S. glabra and 470 bp band special for Ch. spicatus were found by using multi-PCR reaction. The multi-PCR reaction system could be applied to identify S. glabra and Ch. spicatus's leaves.

The study is aimed to assess the genetic diversity and genetic relationship of 18 Sarcandra glabra resources from different populations,and guide parent selection of cross breeding between these resources. The molecular marker technique ISSR was used to investigate the genetic diversity of the 18 resources. Data was analyzed by POPGEN 32, and a cluster diagram was presented by UPGMA. One hundred and ninety-eight amplified fragments were obtained using 23 ISSR primers. One hundred and eighty-four polymorphic loci were identified. Nei's genetic diversity index (h) was 0.32, Shannon diversity index (I) was 0.485 4. The genetic similarity coefficient among the resources ranged from 0.383 8 to 0.878 8 in an average of 0.661 2. The genetic distance between sample S2 and sample S18 was the farthest, so as between sample S3 and sample S18 both Nei's genetic distance was 0.957 5, The genetic distance between sample S4 and sample S5 was the closest, the Nei's genetic distance was 0.129 2,and the sample S1, S2, S3, S7, S10 were significantly different from the others based on the clustering analysis, the three groups S2 vs S3, S2 vs S6, S2 vs S18 were the best parent group selection. There was a middle level of genetic differentiation in the resources. The genetic distance between resources gives useful information to guide parent selection of cross breeding.
