The purpose of this study is to investigate the transdermal delivery characteristics of Gentiana macrophylla complex components system through different parts of the skin under micro-needles conditions. Two-chamber diffusion cells were used, different parts of isolated skin and micro-needle pretreated isolated mouse skin were applied separately, high performance liquid chromatography (HPLC) similarity evaluation methods were used to evaluate transdermal delivery characteristics of Gentiana macrophylla complex components system on receiving pool and the permeation rate and penetration amount of Gentiopicroside at different parts of mouse skin. In the 24 h, the similarity between receiving fluid which was on passive transdermal delivery and micro-needle transdermal delivery conditions and original fluid were ranged from 83.0% to 98.9%; By the micro-needle pretreatment with different parts of the mouse skin, the time that Gentiana macrophylla complex components system though abdominal skin to the receiving fluid which reached 90% similarity compared with that of original fluid was 4 h, which was 18 h at back skin and 12 h at neck skin separately. Micro-needles can be used as the ideal ingredients for traditional Chinese medicine complex transdermal delivery; transdermal absorption time delay could be greatly reduced and its bioavailability was improved. The permeation rate and similarity to original liquid of Chinese medicine complex components increased significantly in the abdominal skin relative to the neck and back skin under micro-needle conditions.

OBJECTIVETo evaluate the analgesic efficacy and systemic anti-inflammation of preoperative cyclooxygenase-2 nonsteroidal antiinflammatory drug, rofecoxib, after total knee replacement (TKR).

METHODSThirty patients underwent elective knee replacement were randomly given oral rofecoxib 25 mg (group RE, n = 15) or placebo (group E, n = 15) 1 hour prior to surgery. All patients received epidural combined isoflurane anesthesia during surgery and patient-controlled epidural analgesia after surgery for 72 hrs (0.1 mg/ml morphine + 1.2 mg/ml bupivacaine + 0.02 mg/ml droperidol). Modified verbal rate scale was used to evaluate postoperative pain intensity. The outcomes included pain scores during rest and movement of knee joints and analgesia satisfaction. Daily morphine consumption was recorded. Circulation leucocyte and serum cytokine concentrations (including interleukin 6, interleukin 8, interleukin 10, Tumor necrosis factor-alpha) were determined before surgery, at the end of surgery, 2 h, 6 h, 12 h, 24 h and 48 h after surgery in two groups using RIA. The amount of intraoperative blood loss and postoperative drainage from the knees were measured.

RESULTSThe pain scores were significantly less in the group RE than in group E during rest and knee joints movement on the first and second postoperative day, with an improvement in total analgesia satisfaction (P < 0.05). The mean dose of morphine for first 24 h was (8.1 +/- 1.5) mg in the E group and (6.8 +/- 0.7) mg in the RE group (t = -2.71, P < 0.01). Leucocyte and neutrophil counts were much higher in group E than in group RE at 12 h, 24 h post-operatively (P < 0.05). Serum TNF-alpha concentration was significantly lower in group RE than group E at the end of surgery, 6 h, 12 h postoperatively, as well as IL6 at 48 h, IL8 at 24h after surgery (P < 0.05). There were no significant differences in respect to the amount of intraoperative and postoperative blood loss between two groups (P > 0.05).

CONCLUSIONPreoperative cyclooxygenase-2-specific nonsteroidal anti-inflammatory drug rofecoxib increases analgesia satisfaction, reduces opioid requirement and demonstrates a systemic anti-inflammatory effect after TKR.

An unusual novel C27-steroidal glycoside sulfate was isolated from the underground organs of Liriope graminifolia (Linn.) Baker with three known compounds. Their chemical structures were determined by spectral analysis, including HR-MS, 1D and 2D NMR as (25S)-ruscogenin 1-sulfate-3-O-alpha-L-rhamnopyranoside (1), (25S)-ruscogenin 1-O-beta-D-xylopyranosyl-3-O-alpha-L-rhamnopyranoside (2), hesperidin (3), and 4', 7-dihydroxy-5-methoxyflavanone (4). Compound 1 has cytotoxic activities against K562 and HL60 cells with IC50 values of 18.6 microg x mL(-1) and 16.5 microg x mL(-1), respectively.

OBJECTIVETo investigate the clinicopathological significance of positive CK7 expression in human colorectal carcinoma (HCC).

METHODSImmunohistochemistry was used to detect CK7 and CK20 protein expressions in 68 cases of HCC, 20 cases of canalicular adenoma (CA), 5 cases of serrated adenoma (SA) and 20 cases of hyperplastic polyps (HP).

RESULTSThe positivity rate of CK20 expression was 89.7% in HCC, and 100% in CA, SA and HP. In HCC, the expression rate of CK7 (39.7%) was not correlated with Dukes' classification, differentiation and tumor location. CK7 positivity rate in colon cancer was 35.7% (15/52) and 42.3% (11/26) in rectal cancer. CK7 expression was negative in CA. CK7 positivity rate in SA was 49% and 30% in HP.

CONCLUSIONCK7 is a possible marker for colorectal carcinogenesis from HP to SA, and ultimately to HCC, and examination of the colorectal polypoid lesions for CK7 expression can be significant for estimating the colorectal polypous cancerization.

OBJECTIVESTo investigate the possibility and efficacy of vasoligation and deferent vein ligation in treating and preventing benign prostatic hyperplasia(BPH).

METHODS40 male pooches were divided into A, B, C and D groups randomly. Each group has 10 pooches group A and B were made into the model of BPH. Two years later, the pooches in group A and C accepted the operation of vasoligation and deferent vein ligation on both sides. Group B and D only accepted the operation of dissection and relieving its deferent duct. Then continuing to feed the 40 pooches after the operation, they were killed another two years later. After taking out their prostates and calculating their volume and weight, the sections of the prostates were checked by microscope to observe their histology and pathology changes.

RESULTSThere were significant differences of weight and volume as well as the changes of histology and pathology between group A and group C (P < 0.01). It was the same with group B and D (hyperplasia changes).

CONCLUSIONSVasoligation and deferent vein ligation before benign prostatic hyperplasia at pooches grow-up stage can reduce the extent of BPH at old age, and treatment after benign prostatic hyperplasia can make prostatic tissue appear different degrees of atrophy.
