To study the impact of five different origin processing methods, namely natural drying, drying in baking shop, drying by microwave heating, drying in drum and drying with sulphur fumigation, on the quality of Lonicerae Japonicae Flos from Donghai cultivation base in Jiangsu Province, with the contents of chlorogenic acid and galuteolin and the similarity in HPLC fingerprints as the evaluation indicators. The results showed that different origin processing methods had significant impact on the content of chlorogenic acid and the similarity in HPLC fingerprints, but with no significant difference on the content of galuteolin. By means of drying by microwave heating and drying in drum, the samples showed higher contents of chlorogenic acid, respectively 3.67% and 3.39%. The similarities of HPLC fingerprints were 0.815 and 0.793, respectively. By means of the drying in baking shop and the drying with sulphur fumigation, the contents of chlorogenic acid in the samples were 2. 87% and 2. 53% , respectively. The similarities of HPLC fingerprints were 0.964 and 0.765, respectively. The lowest content of chlorogenic acid in naturally dried samples was 1.92%. The similarity of HPLC fingerprints was 0.940. According to the findings as well as the internal control standards for Lonicerae Japonicae Flos herbs of Jiangsu Kanion Pharmaceutical Co. , Ltd. , the optimum processing method for Lonicerae Japonicae Flos from Donghai cultivation base was the drying in baking shop. This study provided a theoretical basis for determining the processing method for Lonicerae Japonicae Flos from Donghai cultivation base of Jiangsu Province.

Objective To prepare controlled release microspheres of vascular endothelial growth factor(VEGF)& calcium alginate and observe their effect on proliferation of human umbilical vein endo- thelial cells(HUVEC)in order to provide theoretical basis for controlled release of VEGF facilitating an- giogenesis of tissue engineering bone.Methods VEGF-calcium alginate microspheres were prepared by using the needle extrusion/external gelation method to investigate physicochemical character and in vitro release of VEGF.According to the different ingredients added into the culture medium,the seconda- ry cultured HUVEC were divided into four groups,ie,control group,microsphere group,VEGF group and VEGF-calcium alginate microsphere group,in which the proliferation of the cultured HUVEC was ob- served with cell counting method,MTT method and flow cytometry.Results The calcium alginate mi- crospheres were revealed as spherical shape and evenly distributed,with mean grain diameter of(560?50)?m,carrying capacity of 0.72 ng/mg and the encapsulation efficiency of 54%.Smooth controlled re- lease in VEGF-alginate microspheres lasted for more than 10 days.Proliferation of the cultured HUVEC was accelerated the most in VEGF group at the beginning but in EGF-calcium alginate microsphere group at midanaphase compared with other groups,with statistical difference(P＜0.05).There was no statis- tical difference upon cell counting,cell activity and time point of cell cycle between control group and mi- crosphere group.Conclusion VEGF-sodium alginate microapheres can continue activity of VEGF,re- lease VEGF for over 10 days and promote proliferation cultured HUVEC for a long time.

OBJECTIVETo explore the performance patterns of reaction point Jingtong in balance acupuncture through multi-center and big-sample clinical investigation. Methods The Jingtong points of balance acupuncture on healthy side and affected side were observed among 230 cases of cervical spondylosis and scores of self-discomfort in reaction point, color of skin, changes of skin, morphology of subcutaneous tissue and abnormal pressing pain were recorded. The software SPSS 15.0 was applied to statistically analyze the recorded scores.

RESULTSAmong 230 cases, the reaction point appeared in 226 cases, accounting for 98. 3%. Among the 226 cases who had reaction point, the total score of symptom and sign was (1.08+/-1.09) on the healthy side and (0. 84+/-1. 36) on the affected side, which had statistical significance (P<0. 01); score of self-discomfort in reaction point was (0. 76 +/-0. 83) on the healthy side and (0. 40+/-0.80) on the affected side, which had statistical significance (P<0.01); the score of skin color was (0.10+/-0.36) on the healthy side and (0. 03+/- 0. 19) on the affected side, which had statistical significance (P<0. 05); the score of abnormal pressing pain was (2. 47+/-2. 46) on the healthy side and (1. 39+/-2. 37) on the affected side, which had statistical significance (P<0. 01).

CONCLUSIONThe total score of symptom and sign of reaction point Jingtong on the healthy side is higher than that on the affected side, indicating positive reaction of Jingtong on the healthy side has specificity for cervical spondylosis. When patient has cervical spondylosis on either side of neck, the other side will have anomaly in Jingtong.

OBJECTIVETo explore the antitumoral effect of indirubin on androgen-independent prostate cancer PC-3 cells and its possible mechanisms.

METHODSWe measured the inhibitory effect of indirubin on the proliferation of prostate cancer PC-3 cells using MTT assay, detected their cell cycles by flow cytometry, and determined the expressions of the cell cycle regulatory protein cyclin D1 and its related downstream gene c-myc by Western blot.

RESULTSThe viability of the PC-3 cells was significantly decreased by indirubin in a concentration-dependent manner, reduced to 52. 2% and 13. 6% at 5 and 10 µmol/L, respectively. The cell cycle of the PC-3 cells was markedly inhibited by indirubin at 5 µmol/L, with the cells remarkably increased in the G0 and G1 phases and decreased in the S and G2/M phases. Meanwhile, indirubin also inhibited the expressions of cyclin D1 and c-myc in the Wnt signaling pathway.

CONCLUSIONIndirubin can suppress the proliferation of androgen-independent prostate cancer PC-3 cells, which may be associated with its inhibitory effect on the cell cycle and Wnt signaling pathway.

OBJECTIVETo understand the demographic, occupational and clinic characteristics of occupational poisoning case due to trichloroethylene in Dongguan in recent years for the purpose of prevention.

METHODSUsing the trichloroethylene patients of poisoning diagnosed in the years between 2002 to 2009 as subjects, their age, sex, industry, job, working duration and exposure level were analysed.

RESULTSIn Dongguan between 2002 and 2009 altogether 82 cases were reported, among the 82 cases 8 patients were dead with case fatality rate of 9.8%. among them there were 12 cases of poisonings(8 females ,4 males); 9 cases were classified as mild poisonings and the rest serious ones, among the 12 cases 3 patients were dead with case fatality rate of 25.0%; Dermatitis caused by TCE there were 70 cases (37 males and 33 females), among the 70 cases 5 patients were dead with case fatality rate of 7.1%. 11 persons (91.7%) were engaged in the job of cleaning and 1 (8.3%) in water gun, and they performed the job only for 3 days in shortest and for 450 days in longest. The cases were distributed in the jobs as the following: 29 (41.4%), 12 (17.1%), 8 (11.4%), 5 (7.1%), 4 (5.7%), cases respectively in the job of cleaning, parts hanging, board washing, painting, gun water spraying; a job duration of 1-50 d (27.4 days in average).

CONCLUSIONIn summary the TCE poisonings in Dongguan were two types of poisoning, i.e., systematic poisonings and drug rash-like dermatitis, occupational TCE poisonings took place mainly in the cleaning workers. Dermatitis caused by TCE can cure but hard to prevent, we should strengthen the early examination of new works.

OBJECTIVETo investigate the feasibility and advantages of transurethral transumbilical laparoendoscopic single-site surgery (TU-LESS) for radical prostatectomy.

METHODSFive patients with prostate cancer underwent TU-LESS for radical prostatectomy, with a four-channel single-port device inserted into a 2. 5 cm periumbilical incision and another placed through the urethra, followed by analysis of the perioperative data.

RESULTSAll the operations were successfully accomplished, with neither conversion to open surgery nor additional channel. The mean operation time, intraoperative blood loss, and postoperative hospital stay were 168 min, 120 ml, and 15 d, respectively. No severe perioperative complications were observed. TNM stage classification manifested T2cN0M0 in 2 cases and T2bN0M0 in the other 3. Postoperative pathology showed no negative surgical margins in any of the cases.

CONCLUSIONTU-LESS is safe and feasible for radical prostatectomy and can reduce the complication of low urinary tract surgery by single-site laparoendoscopy.
