OBJECTIVETo investigate the effect of 6-gingerol, the main active component of ginger, on hair shaft elongation in vitro and hair growth in vivo.

METHODSFirstly, Hair follicles were co-cultured with 3 different concentration of 6-gingerol for 5 days and hair elongation in three groups was measured. Secondly, The proliferative effect of 6-gingerol on DPCs was measured using MTT assay. Thirdly, the expression of Bcl-2 and Bax in DPCs were measured using Western blotting. In vivo study, the influence of 6-gingerol on hair growth in C57BL/6 rats was measured through topical application of 6-gingerol on the dorsal skin of each animal.

RESULTSThe length of hair shaft in 20 microg/ml 6-Gingerol group (0.50 +/- 0.08 mm) is less than 0 microg/ml (0.66 +/- 0.19) mm and 10 microg/ml (0.64 +/- 0.03) mm 6-Gingerol group (P < 0.05). In cell culture, compared to 0 microg/ml and 5 microg/ml 6-Gingerol, 10 microg/ml 6-Gingerol can significantly inhibited the proliferation of DPCs (P < 0.05). Along with the growth inhibition of DPCs by 6-gingerol, the Bax/Bcl-2 ratio increased obviously. In vivo study, the hair length and density decreased a lot after using 1 mg/ml 6-gingerol.

CONCLUSIONS6-Gingerol can suppress human hair shaft elongation because it has pro-apoptotic effects on DPCs via increasing Bax/Bcl-2 ratio. It might inhibit hair growth by prolonging the telogen stage in vivo.

To investigate the modulation on the P-glycoprotein in the jejunum by combined use of Glycyrrhiza inflata and Kansui with ussing chamber and rt-pcr, Rhodamine 123 (R123), a P-gp substrate and fluorescein sodium (CF), a model drug of non-P-gp substrate transported by a passive diffusion were taken as investigational drugs. Because these two drugs can be easily assayed and widely used in various research fields. The permeability of R123 or CF via Wistar rat jejunum membranes was evaluated by in vitro ussing chamber after oral administration of four different decoctions of Glycyrrhiza inflata and Kansui for 1 week. And the concentration of R123 or CF was determined by the fluorospectrophotometry in the receiving solution. Meanwhile the expression of mdr1a in P-glycoprotein was detected by real-time fluorescent quantitative PCR. After oral administration of combined decoction of the single drug, the absorptive directed permeability of R123 increased significantly (P < 0.01). On the other hand, Kansui and combine decoction of the two drugs also decrease the permeability of secretory directed transport (P < 0.05). No action of Glycyrrhiza inflata was found on the secretory transport of R123 [Papp = (2.56 +/- 0.38) x 10(-5), cm x s(-1)] across the jejunum tissues, while Papp of control group was found [Papp = (2.35 +/- 0.27) x 10(-5), cm x s(-1)]. After oral administration of Kansui decoction for 1 week and 2 weeks, the levels of mdr1a expression in Wistar rats were lower than that of the control group, but there were no significant difference in the results. Meanwhile, Glycyrrhiza inflata had no effect on transport of CF across the jejunum tissues, though the other three groups could decrease the permeability of CF, as compared with control group. Kansui may slightly inhibit P-glycoprotein function in the intestinal membrane. For another, some compositions in Kansui inhibit P-glycoprotein function, and some others strengthen the tight junction between cells in the intestinal membrane to decrease permeability of CF. As the inhibitory action to P-glycoprotein was enhanced by combination of Glycyrrhiza inflata and Kansui, based on the results, it may be one of the mechanisms of creating toxicity once co-administration of Glycyrrhiza inflata and Kansui.

Objective To observe the perioperative myocardial protection of high-dose atorvastatin to acute coronary syndrome(ACS) patients during percutaneous coronary artery interventional therapy(PCI).Methods One hundred and twenty patients with ACS undergoing elective PCI were divided into group A and group B with different oral dose of atorvastatin ( 80 mg/d and 20 mg/d ) for 3 days before operation by random digits table. Troponin I (cTnI), creatine kinase isozyme MB (CK-MB), high sensitive C-reactive protein (hs-CRP), interleukin (IL)-6 levels were measured before operation, 6 hours, 12 hours after operation and total cholesterol (TC), triglyeride (TG), low desity lipeprotein cholesterol (LDL-C), high density lipeprotein cholesterol (HDL-C) levels were measured before operation and 3 days after operation.Results cTnI,CK-MB,hs-CRP and IL-6 levels in the two groups were increased significandy 6 hours and 12 hours after operation (P <0.05). Six hours after operation, cTnI and CK-MB levels in group A were significantly lower than those in group B [(0.35±0. 18 ) μg/L vs. (0.48±0. 16 ) μg/L, ( 3.78±0.45 )μg/Lvs. (4.56±0.55 )μg/L] (P < 0.05 ). Twelve hours after operation , hs-CRP and IL-6 levels in group A were significantly lower than those in group B [(4.53±0.98 ) mg/L vs. (7.03±0.88 ) mg/L, ( 30.6±11.2) ng/L vs.(43.8±12.1) ng/L] (P <0.05). TC, TG, LDL-C, HDL-C levels in the two groups did not change significantly before and after operation (P >0.05). Conclusions Myocardial protective effects of ACS patients treated with atorvastatin 80 mg/d for 3 days are better than those treated with oral atorvastatin 20 mg/d. High-dose atorvastatin can produce more beneficial effects.

OBJECTIVETo identify the mutations of iduronate-2-sulfatase (IDS) gene, to reveal its mutation features, and to establish a basis for genetic counseling and prenatal gene diagnosis of Hunter syndrome.

METHODSUrine glycosaminoglycans (GAGs) assay, PCR and DNA sequencing were performed to detect mutation of IDS gene of the patient and his parents.

RESULTSThe result showed that the patient was: DS(++), HS(++), KS(-), CS(-), and that both of his parents were negative. A frame-shift deletion mutation (1062 del 16) was identified in exon 7 of the patient's IDS gene. His parents' genotypes were normal.

CONCLUSIONThe patient's mutation was not inherited by his parents but a novel one. The mutation probably altered the primary structure and tertiary structure of IDS enzyme protein remarkably and lowered the activity of IDS enzyme greatly. Therefore it is supposed to be the direct cause of the disorder.

Objective To explore the endoscopic and clinicopathological characteristics of upper gastrointestinal tract metastasis,it can improve the diagnosibility of endoscopists and pathologists. Methods Three cases of upper gastrointestinal tract metastasis and seven cases in the related literature were studied, and its endoscopy and clinicopathological findings were analyzed with a review of the literature, whose gastrointestinal symptoms were the first manifestation. Results Case 1 endoscopic detection of esophageal ulcer lesions, pathological diagnosis of metastatic cancer, considering the source of the lung, confirmed by imaging examination; Case 2 showed that the gastric body was prominent, and the pathological diagnosis was squamous cell carcinoma. It was suggested that the clinical examination should be carried out without metastasis, and then confirmed by imaging examination and bronchoscopy biopsy; Case 3 endoscopic examination revealed multiple polypoid lesions in the stomach and duodenum, and was pathologically diagnosed as metastatic renal cell carcinoma. 3 patients were correctly diagnosed, thus avoiding unnecessary radical surgical treatment. 7 cases of patients in the literature were aged, they were also in a variety of gastrointestinal symptoms and the first diagnosis, no previous history of cancer, endoscopic lesions in the stomach or duodenum, supplemented by immunohistochemical staining in pathological diagnosis were diagnosed as metastases, the primary tumor site without organ specific. Conclusion The metastasis of upper gastrointestinal tract is rare, especially when the gastrointestinal symptoms were the first manifestation,it is usually missed and misdiagnosed. The diagnosis relies on the endoscopic and pathological examination, supplemented by the imaging examination, so the patients could get effective treatment in time.

OBJECTIVETo investigate the effect of nanometer hydroxyapatite on the proliferation and the osteogenetic differentiation of periodontal ligament cells (PDLC).

METHODSNano-hydroxyapatite powders were fabricated with sol-gel method. The fourth passage periodontal ligament cells were cultured with nanometer hydroxyapatite powder (nano-HA), dense hydroxyapatite powder (dense-HA) and only medium as control respectively. On the 5th, 8th day of culture, the osteogenetic differentiation of human periodontal ligament cells was evaluated though alkaline phosphatase (ALP) activity, ALP immunohistochemical stain and ALP positive flow cytometry.

RESULTSThere were significant differences among nano-HA group, dense-HA group and control group on the 5th and 8th day of culture. A majority of nano-HA group and dense-HA group cells sample showed positive ALP stain. But the ALP positive stain of nano-HA group cells sample was denser than that of dense-HA group. In FCM, the distribution of ALP positive cells cultured with nanoparticles were significantly more than that of other groups.

CONCLUSIONSThe nano-HA, as a calcium phosphate biomaterial, has ability to promote the activity of osteogenetic differentiation for periodontal ligament cells compared with dense-HA.

OBJECTIVETo primarily seek for unstable angina (UA) correlated metabolic markers and to observe the effects of Yangxin Decoction on the plasma metabolism of UA patients.

METHODSTen UA patients from clinics of No. 2 Circulation Department, First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine from November 2009 to December 2010 were recruited as the treatment group. Another 10 healthy volunteers were recruited as the control group (Group D). The changes of plasma metabolic components were observed in UA patients after they took Yangxin Decoction for 28 days, using liquid chromatography mass spectrometry (LC-MS). Analysis was conducted using principle component analysis (PCA) and partial least squares (PLS) to seek for UA correlated metabolic markers.

RESULTSResults of PCA among Group D (the healthy group), Group M (UA group before medication), and Group G (UA group after medication): all samples of the three groups were centrally distributed in the four score plot of the oval regions (95% confidence interval). In Group M, the relative dispersion of the sample 8, 9, and 10 was near to Group D. The samples of the three groups could be separated. The samples of Group M (before medication) and Group G (after medication) could be basically separated. Comparison of metabolic end products between Group D and Group M: In the metabolites of UA group, ceramide, glycocholic acid, allocholic acid, lithocholic acid, leukotriene B4 obviously increased.

CONCLUSIONSCeramide, glycocholic acid, allocholic acid, lithocholic acid, leukotriene B4 might be metabolic markers of UA. Yangxin Decoction might have effects on some plasma metabolites or metabolic pathways of UA patients.

OBJECTIVETo compare primary anastomosis after intraoperative colonic defecation and Hartmann procedure for obstructive left colon cancer.

METHODSClinical data of 68 patients who underwent emergent laparotomy for left colon cancer with acute bowel obstruction between January 2000 and January 2008 were analyzed retrospectively.

RESULTSPrimary resection and anastomosis with intraoperative defecation was performed in 43 patients and Hartmann's procedure in 25 cases. Patients in both groups were comparable in terms of age, gender, nutritional status, underlying diseases, tumor location and stage, etc. The morbidity and mortality in the two groups were 25.6% vs 28.0% (P=0.761) and 2.3% vs 4.0% (P=0.369), respectively, and the differences were not statistically significant. The length of hospital stay (including first resection operation and second admission for colostomy closure) was (16.6+/-7.8) d in the primary anastomosis group and (24.6+/-9.4) d in the Hartmann procedure group, and the difference was statistically significant (P=0.002). The costs of hospitalization in the two groups were CNY 50,192.8+/-39,727.4 and CNY 58,382.1+/-30,304.9 (P=0.020).

CONCLUSIONPrimary resection with intraoperative colonic defecation is safe and effective, and should be considered as an alternative to Hartmann procedure for obstructive left colon cancer in selected patients.
