China Pharmacy 2007;0(31):-
OBJECTIVE: To optimize the extraction technology of Huanggan decoction. METHODS: The extraction technology of Huanggan decoction was optimized by L9(33) orthogonal design with the concentration of alcohol, the amount of solvent and the extraction time as factors taking the contents of chlorogenic acid as indexes. RESULTS: The optimal extraction process was as follows: adding six and five-fold of 70% alcohol, extracting for 60 min and 45 min. CONCLUSION: The extraction technology has been proved to be reasonable, simple and feasible, and it provides theory evidence for production.
2.Advance in current management of patients with anaplastic thyroid carcinoma
China Oncology 2014;(4):310-315
Anaplastic thyroid cancer (ATC) is the most aggressive thyroid tumor, with lower morbidity and higher mortality rates. Radical surgery could improve local control and survival rates. Conformal radiotherapy is superior to conventional radiotherapy, which could improve the patients’ quality of life. There are a few chemotherapeutic drugs against ATC, and the outcome of chemotherapy alone is modest. Concurrent chemoradiotherapy can prolong the survival. Targeted therapy brings new hope for refractory patients. Many cancer centers are exploring surgery, radiotherapy, chemotherapy, targeted therapy and other biological treatment of comprehensive application, in order to enhance the curative effect. This article reviewed the foregoing treatments for ATC.

The effects of Trichostatin A (TSA) on histone deacetylase 8 (HDAC8) expression, proliferation and cell cycle arrest in T-lymphoblastic leukemia cell line Molt-4 cells in vitro were investigated. The effect of TSA on the growth of Molt-4 cells was studied by MTT assay. Flow cytometry was used to examine the cell cycle. The expression of HDAC8 was detected by using immunocytochemistry and Western blot. The results showed that proliferation of Molt-4 cells was inhibited in TSA-treated group in a time- and dose-dependent manner. The IC50 of TSA exposures for 24 h and 36 h were 254.3236 and 199.257 microg/L respectively. The cell cycle analysis revealed that Molt-4 was mostly in G0/G1 phase, and after treatment with TSA from 50 to 400 microg/L for 24 h, the percents of G0/G1 cells were decreased and cells were arrested in G2/M phase. Treatment of TSA for 24 h could significantly inhibit the expression of HDAC8 protein in Molt-4 cells (P<0.01). It was concluded that TSA could decrease the expression of HDAC8 in Molt-4 cells, which contributed to the inhibition of proliferation and induction of cell cycle arrest in Molt-4 cells.

Current therapies for chronic hepatitis caused by hepatitis C virus (HCV) are limited . DNA vaccination may constitute a new immunotherapeutic strategy for various hepatitis virus infections by promoting specific cellular and humoral immunity. In this review we present the advances in choice of antigen gene, vaccine adjuvants and the methods of intracellular delivery, unresolved questions and therapeutic potential of HCV DNA vaccine.

Objective To explore the application value of uterine incision suture in multiple segment shrinkage in cesarean section.Methods 85 pregnants with uterine scar who taken cesarean section were selected.In the single month,the pregnants were included in the observation group(43 cases):after pruning scars,uterine lower segment weak muscle tissue by wrinkling suture to reinforce the thickness of the lower segment again from both sides of the suture,intermediate knotted suture the uterine incision.In the bimonth,the pregnants were included in the control group(42 cases):after pruning scars by conventional suture incision of lower uterine segment.The duration of vaginal bleeding time after operation ,postoperative 42 days ,3 months ultrasonography of uterine incision healing were observed.Results The postoperative vaginal bleeding volume of the observation group was less than that of the control group[(480.55 ±53.75)mL vs.(550.14 ±50.45)mL],the bleeding time was less than that of the control group[(21.31 ±6.78)d vs.(30.45 ±5.16)d],the differences were statistically significant(t =3.65,2.28,all P <0.05).March B -ultrasonography uterine incision after surgery,the good healing rate of the observation group was 95.35%,which of the control group was 78.57%,the difference was statistically significant(χ2 =4.35,P <0.05). Conclusion Incision under section shrinkage joint is conducive to the incision structure and muscle layer mechanical recovery and can reduce the amount of vaginal bleeding and time and defect healing of incision morphology.

Objective To investigate the effects of substance P (SP) on the expression of apoptosis-associated genes in fibroblasts derived from pathological scars. Methods Fibroblasts derived from keloid, hypertrophic scar and normal skin were cultured separately in media containing SP and SP receptor antagonist. PCNA, bcl-2 and bax protein in fibroblasts were assessed by means of immunohistochemistry. Results SP enhanced PCNA and bcl-2 expression in all three kinds of fibroblasts, whereas, bax expression was inhibited significantly. SP inhibited the expression of bax in keloid scar fibroblasts (KSFB) more remarkably than that in hypertrophic scar fibroblasts (HSFB) or normal fibroblasts (NFB), and the effect was stronger on HSFB than on NFB. SP receptor antagonist could inhibit those effects of SP totally or partially. Conclusion SP may play an important role in the formation of pathological scars by modulating the expression of apoptosis-associated genes, which is mediated by SP receptor.

BACKGROUND:The large watercress molded piece is longer than that of the normal molded piece, which is suitable for dental restoration of elderly patients with gingival recession and relatively long crown.
OBJECTIVE:To test and verify the effect of large watercress molded piece on the auxiliary repair of approximal caries lesions in molars of the elderly.
METHODS:Eighty-seven senile patients with molar approximal caries were randomly divided into two groups: those were repaired by large watercress molded piece as experimental group, and those repaired by traditional amalgam molded piece ascontrol group. Then we compared the comfortable satisfaction rate, the excelent and good rate of repair and the gingival index between the two groups immediately, 1, 3, 6 and 12 months after repair.
RESULTS AND CONCLUSION:The comfortable satisfaction rate of the experimental group was significantly higher than that of the control group at 1, 3, 6 and 12 months after repair (P< 0.05), and the gingival index was significantly lower than that of the control group (P< 0.05). The excelent and good rate of the experimental group was significantly higher than that of the control group at different time points after repair (P< 0.05). No loss or fracture of the restorations occurred in the two groups. These results demonstrate that the large watercress molded piece for repairing approximal caries lesions in molars of the elderly can better restore the anatomical shape and approximal points of teeth, and reduce food impaction and gingival inflammation.
