To discuss the relationship between Chinese medicine processing and medicine usage.After being processed,characteristics of Chinese medicine can be changed,the performance be mitigated,and some side effects be reduced or eliminated,which makes its clinical usage more rational and effective.besides,medicine processing can also change the taste and reduce bad smell of medicines.

The rapid advances over the past decades in molecular biology led to new ideas and methods to investigate the mechanism of depression, which enlarged the views of fields from neurological transmitters and related receptors to post-receptor signal transduction levels. It not only help to elucidate the pathogenesis of depression, but also offer beneficial evidence for development of new antidepressants. This paper reviews the development of molecular biological study in depression.

Objective To study and analyze the effect of fluoride faction shouted tons melitracen sheet (Deanxit)on abdominal pain symptoms of functional gastrointestinal disorders (FGIDs).Methods 82 patients with abdominal pain FGIDs were randomly divided into A group(n =40)and B group(n =42).A group was given conven-tional treatment,group B was given deanxit treatment on the basis of A group.The treatment efficacy and the total inci-dence of adverse reactions were analyzed.Results The total effective rate of group B (90.24%)was significantly higher than that in group A (65.85%),the difference was statistically significant (χ2 =4.538,P <0.05).There were no serious adverse reactions observed during treatment in the two groups,the incidence rate of adverse reactions between the two groups had no statistically significant difference (P >0.05).Conclusion Deanxit in the treatment of FGIDs can achieve satisfactory therapeutic effect,the drug can significantly alleviate the symptoms,andit is safe and without serious side effects.

It was shown that in the stricture on abdominal aorta (SAA) rat myocardiac hypertrophy model,the caudal blood pressure was increased,the wall of left ventricle was thichened, the proliferation of T cell in thymus and spleen was decreased and the content of IL-2 was less than normal. Acanthopanax giroldii polysaccharide (AGPS10mg/kg.d, sc) could harmonize the heightened blood pressure and increase the level of immunity in the body. It was suggested by the result, that AGPS could be used to strengthen the heart function as well as immunity.

Test on coagulation time,prothrombin time and platelet aggregation of mice and rats showed that all four species of Puhuang had effects on blood coagulation, in which Typha angustata Bory et Chaub. was the strongest followed by T. davidiana Hand. -Mazz., T. latifolia L,and T. angustifolia L. Their mechanism of coagulation were not the same,in which T. angustata Bory et Chaub. mainly acted on thrombogen,while T.davidiana Hand. -Mazz. mainly acted on platelet aggregation.

Body weight, height, weight index as well as obesity incidence of 4780 people (male 3216, female 1564) aged from 20 to 78 including various kinds of job were investigated in Fusan district in Shandong province. The body weight and height were measured by conventional method. The weight indexwas estimated in terms of the value of weight(kg)/height(cm)2 ? 100. The correlationregression between sex, age, height and weight was calculated as well.The result showed that the average weight index ranging from 0.1933 to 0.2525 in males and 0.1951 to 0-2563 in famales was noticed. Accordingly, the incidence of overweight and obesity was 7.71% and 8.33% in males and 6.96% and 4.73% in females respectively. The correlation coefficients between weight and age (r = 0.9838 within 20-35 in age in males, r = 0.9846 within 20-50 in age in famales), and between weight and height (r = 0.9798 within 144-180cm in males, r = 0.8595 within 140-170cm in females) were highly significant.The data mentioned above were also discussed briefly.

Objective To analyze the relation between lamivudine-resistant mutation types and HBV genotypes.Methods 95 cases with YMDD mutation were selected from out-patient clinic and sickroom in our hospital.Restriction endonuclease MboⅠand EarⅠwere used to identify HBV genotypes of PCR product, farther a phylogenesis tree was applied to check it.Results We could divide 95 cases into two parts, 75 cases(78.95%) were HBV C genotype and 20 cases(21.05%) were B genotype, these were verified by phylogenesis tree.With regard to the types of YVDD mutation、YIDD mutation and YMDD+YVDD+YIDD mutation, there were 11 cases, 5 cases, 4 cases in genotype B, respectively, but 35 cases, 27 cases, 13 cases in genotype C.We made the cha-test to check genotypes and types of YMDD mutation, ?2= 0.856, P=0.710. There were no significant differences.Conclusions Using MboⅠand EarⅠcan genotype HBV PCR product easily and reliably. It is no statistical significance between HBV B or C genotype and the types of YMDD mutation.

Objective: To investigate the infection state of hepatitis C virus genotype 6a in China.Methods: Three(95,126,150)HCV genotype 6a serum samples were identified by digesting 5′NCR with compound enzyme method.Then,HCV 5′NCR and NS5B fragments were amplified from these samples by RT-PCR assay and sequenced.The phylogenetic trees of the samples were analyzed and compared with 24 HCV complete gene sequences from GenBank.Results: The sequencing reports on 5′NCR showed "CA" bases in 3 serum samples(95,126,150) were inserted into-145 site,and the sequences of 3 serum samples had the highest homology with sequence Y12083(0.934,0.930,and 0.926,respectively).The results of the phylogenetic trees suggested these 3 serum samples belonged to HCV genotype 6a.The sequencing reports on NS5B showed the 3 serum samples also had the highest homology with HC-J4(0.934,0.930,and 0.926,respectively),and the results of the phylogenetic trees suggested these 3 serum samples belonged to HCV genotype 1b.To exclude the influence of amplification efficiency of primers,NS5B fragments were amplified by HCV genotype 6a specific primers and no amplification products appeared.Conclusion: There are different results of HCV genotype by analyzing 5′NCR and NS5B in 3 samples infected with HCV genotype 6a.It may be related with gene recombination.It suggests HCV genotype should be analyzed on more than two regions.

Papillary thyroid microcarcinoma (PTMC) is a subtype of papillary thyroid cancer,and there are many debates about its treatments,including extent of thyroidectomy,necessity of prophylactic central-neck nodal dissection,risk-benefit ratio of thyroid-stimulating hormone suppression and indications of observation therapy,et al.The epidemiology and treatment programs of thyroid PTMC were reviewed in this article.

Objective To evaluate the changes in the expression of NRF-1 in the spinal cord during remifentail-induced hyperalgesia in a rat model of incisional pain.Methods Forty-eight Sprague-Dawley rats,weighing 180-220 g,were randomly divided into 4 groups (n =12 each) using a random number table:control group (C); incisional pain group (group Ⅰ); remifentanil group (group R); incisional pain + remifentanil group (group Ⅰ + R).All the rats were anesthetized with sevoflurane.A 1-cm longitudinal incision was made through skin,fascia and muscle of the plantar aspect of the right hindpaw in I and I + R groups.In C and I groups,normal saline was subcutaneously infused for 30 min.In group I + R,remifentanil (0.04 mg/kg,0.4ml) was subcutaneously infused for 30 min starting from the onset of skin incision.Paw withdrawal threshold to mechanical stimulation (PWMT) was measured at 24 h before operation and at 2,6,12,24 and 48 h after operation.After measurement of PWMT at 48 h,the rats were sacrificed and L4,5 segments of the spinal cord were removed rapidly to detect the expression of nuclear respiratory factor 1 (NRF-1) by immunofluorescence and Western blot.Results Compared with group C,PWMT was significantly decreased at each time point after operation,and the expression of NRF-1 in the spinal cord was up-regulated in I and I + R groups (P ＜ 0.05).Compared with group I,PWMT was significantly decreased at each time point after operation,and the expression of NRF-1 in the spinal cord was up-regulated in group I + R (P ＜ 0.05).Conclusion Up-regulation of NRF-1 expression in the spinal cord may be involved in the development of remifentail-induced hyperalgesia in a rat model of incisional pain.
