Conclusion: Therefore, the ultrafiltration should be used with caution in eliminating pyrogens of injection of Chinese medicinals.

To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective To prohc into the distinguished feature of postoperation of early inflammatory intesti- nal and the principle of diagnosis and treatment.Methods 23 cases of early intestinal postoperatively treated during the year of 2003 to 2005 were analysed.Results In the 23 cases,20 of them were treated conservatively while 3 of them were treated operatively,both of which were recovered and dischanged from hospital.Conclusion The early inflammatory intestinal postoperatively is a kind of special one in which both mechanical factor and dynamic factor could be found.Most of the patients could be cured by conservative way and they should surely be in closed observa- tion of the condition in order to be handled properly.

To ascertain the optimal harvest period of Lonicera Flos (Lonicera macranthoides) the configuration yield and quality of L. macranthiodes bloom verity and bud verity flower at different develop periods were Observed. The quality of L. macranthiodes which harvested at different times of the day was Compared. The configuration was significant difference between different develop period of L. macranthiodes flower. As bud growth, yield increased. Bloom verity of L. macranthoides chlorogenic acid content was significantly lower after opening (silver flower stage, golden flower stage), before opening (young bud stage, green-white stage) have no significant difference of the quality. Bud verity of L. macranthoides macranthoidin B is significant lower at yellow-white stage, young bud stage and green-white stage have no significant difference of the quality. The chlorogenic acid and isochlorogenic acid A content is significant difference between L. macranthoides harvested at different time of the day. The optimal harvest period of bloom verity is the white stage, picking time for 10:00 before and after 18:00. The optimal harvest period is the green-white stage, picking time is 8:00 before and after 18:00.

To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) and TACE alone for hepatocellular carcinoma (HCC), Pubmed, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Datebases were searched for the randomized controlled trials (RCTs) and retrospective cohort studies from the establishment of the databases to January 2014. The bibliographies of the included studies were searched, too. After study selection, assessment, data collection and analysis were undertaken, we performed this meta-analysis by using the RevMan5.2 software. Seventeen studies involving 1116 patients met the inclusion criteria with 530 treated with RFA-plus-TACE and 586 with TACE alone. The results of meta-analysis showed that the combination of TACE and RFA was obviously associated with higher 1-, 2-, and 3-year overall survival rates (OR1-year=3.98, 95% CI 2.87-5.51, P<0.00001; OR2-year=3.03, 95% CI 2.10-4.38, P<0.00001; OR3-year=7.02, 95% CI 4.14-11.92, P<0.00001) than TACE alone. The tumor complete necrosis rate in patients treated with TACE and RFA was higher than that of TACE alone (OR=13.86, 95% CI 8.04-23.89, P<0.00001). And there was a significant difference in local recurrence rate between two different kinds of treatment (OR=0.24, 95%CI 0.14-0.44, P<0.00001). Additionally, combination of TACE and RFA was associated with higher complete tumor necrosis rates than TACE mono-therapy in the treatment of HCC. However, RFA plus TACE was found to be associated with a lower local recurrence rate than TACE monotherapy. TACE-plus-RFA treatment was associated with a higher response rate (RR) than the TACE-alone treatment (OR=3.90, 95% CI=2.37-6.42, P<0.00001). TACE-plus-RFA treatment did not differ from the TACE-alone treatment in terms of stable disease (SD) rate (OR=0.38, 95% CI=0.11-1.26, P=0.11). Meta-analyses showed that the combination of RFA and TACE was associated with a significantly lower progressive disease (PD) rate (OR=0.15, 95% CI=0.05-0.43, P=0.0005). The rate of AFP reducing or returning to normal in serum in RFA plus TACE group was obviously lower than TACE alone group (OR=4.62, 95% CI 2.56-8.34, P<0.00001). The effect of TACE plus RFA for HCC is better than TACE mono-therapy. The combined therapy can elevate the patients' overall survival rate, tumor necrosis rate and the rate of AFP reducing or returning to normal in serum and decrease local recurrence rate, PD rate compared with TACE alone.

The author detected the genetic diversity and genetic relationship within and among eight medicinal species of Dipsacus by the approach of sequence-related amplified polymorphism (SRAP). The associated genetic parameters were calculated by POPGENE 1.31. The Genetic distance was calculated by TREECONW and the systematic diagrams of genetic relationship were clustered by UPG-MA. The results showed that, using 26 primers, a total of 558 bands were produced, of which 539 were polymorphic loci. There was a high level of genetic diversity among species (PPB = 96.59%, Na = 1.9659, Na = 1.3375, H = 0.2143, I = 0.3423). However, genetic diversity was lower within species, the average of genetic parameters was PPB = 6.97%, Na = 1.0697, Na = 1.0311, H = 0.0187, I = 0.0291. The Nei's genetic differentiation coefficient was 0.9126, indicated that most of the genetic variation existed among species. By clustering analysis, different individuals gathered in the same group and the classified result of SRAP marker between traditional modal characters was almost same. The results confirmed that SRAP marker can be used as one of the effective methods to reveal the genetic diversity and relationship among medicinal species of Dipsacus.

[Objective] To investigate the effects of airway dysbacteriosis on the development of murine atlergic airway diseases (AAD).[Methods] Female C57BL/6 mice were neubulized with Vancomycin for 10 days and then were sacrificed.The bacterial population in bronchoalveolar lavage fluid (BALF) were evaluated using 16S rRNA high-throughput sequencing technology,exploriug the method of establishing an airway dysbacteriosis mouse model.After the mouse model was established successfully,airway dysbacteriosis mouse models were established by the same method,and based on that,the mice were sensitized and challenged with ovalbumin (OVA) to induce airway allergic inflammation.The frequency of nasal rubbing behaviors per mice was counted;the total cell number and eosinophil relative abundance in BALF were evaluated;the lung tissue inflammation and goblet cell metaplasia were assessed according to histopathological features;and the IgE level in serum,IFN-γ,IL-4 and IL-5 levels in BALF,and IL-33 levels in serum,BALF and intestine tissue were measured by ELISA.[Results] Nebulization of Vancomycin increased Bradyrhizobium,Sphingopyxis,Cupriavidus,Pelomonas,and decreased Akkermansia and Prevotella_6 in airway,inducing significant airway dysbacteriosis.Using the animal model,further study found that airway dysbacteriosis exacerbated OVA-induced airway allergic inflammation,including increased nasal rubbing frequency,higher serun IgE level,more total cell count especially eosinophil infiltration,more serious lung tissue inflammation and goblet cell metaplasia.Additionally,compared to OVA group,mice in Dysbacteriosis and OVA group had significantly increased level of Th2 cytokine IL-4 and IL-5,and significantly decreased Thl cytokine IFN-γin BALF,which revealed that mice in Dysbacteriosis and OVA group had mote remarkable Thl/Th2 imbalance.Furthermore,IL-33 level showed a significant increase in BALF,but didn't change in serum or intestine tissue in Dysbacteriosis and OVA group compared to OVA group.Indicating that airway dysbacteriosis may only affect the local production of IL-33.[Conclusions] An airway dysbacteriosis mouse model was established by Vancomycin nebulization successfully.Airway dysbacteriosis may activate innate lymphoid cells (ILC) and Th2 cell by inducing local IL-33 secreting,which leads to the imbalance of Th1/Th2,and in turn promotes the development of AAD.

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.

To reveal the genetic diversity and genetic structure in Artemisia annua varieties (strains) populations, we detected the genetic polymorphism within and among eight varieties (strains) populations (192 individuals) by the approach of Start Codon Targeted Polymorphism (SCoT). The associated genetic parameters were calculated by POPGENE1.31 and the relationship was constructed based on UPGMA method. The results showed that, using 20 screened primers, a total of 145 bands were produced, of which 122 were polymorphic loci. At species level, there was a high level of genetic diversity among eight varieties (strains) populations (PPB = 84.1% ,H = 0.217 3 and H(sp) = 0.341 9). However, at the variety (strains) population level, genetic diversity was lower, the average of genetic parameters was PPB = 41.9%, H = 0.121 5, H(pop) = 0.186 8. The Nei's genetic differentiation coefficient was 0.441 0, indicate that most of the genetic variation in this species existed within the variety populations. The gene flow (N(m) = 0.633 9) was less among populations, indicating that the degree of genetic differentiation was higher. Genetic similarity coefficient were changed from 0.755 1 to 0.985 7. By clustering analysis, eight varieties (strains) were clustered into two major categories and it was also showed the same or similar genetic background varieties (strains) have a tendency to gather in the same group. Results suggest that, in variety breeding, breeders should strengthen the exchange of bred germplasm and increase mutual penetration of excellent genes, which would broaden the genetic base of A. annua.
