OBJECTIVETo observe the therapeutic effect of Dachaihu Decoction (DCHD) on acute mild pancreatitis of Gan-qi stagnant syndrome type.

METHODSThirty-six acute pancreatitis patients were randomized into three groups (Group A, B and C) equally, and they were treated with conventional Western medicine (WM), WM plus placebo and WM plus DCHD, respectively for 7 days. The time for pain relieving, fasting and total hospitalization were observed, and serum amylopsin and C-reactive protein (CRP) levels were measured before treatment and at various time points after treatment.

RESULTSAfter treatment, amylopsin and CRP level significantly decreased in the 3 groups, comparing with those before treatment (P < 0.05, P < 0.01). In Group C, amylopsin level was obviously higher on dl, d3 and d5, CRP level was higher on dl, d3, d5 and d7, and the remission time of abdominal pain, the fasting time, as well as the hospitalization time were all significantly shorter than those in Group A and B (P < 0.05, P < 0.01).

CONCLUSIONThe accessory use of DCHD upon conventional Western medical treatment can strikingly shorten the course of disease and enhance the therapeutic effect on mild acute pancreatitis patients.

OBJECTIVEThe aim of this investigation was to examine the anatomic basis of palatopharyngeus and clinical implications for sphincter pharyngoplasty.

METHODSDetailed dissections were performed on 17 sides of adult human head and neck specimens. The eight sides newborns' head and neck cadavers were also used in the study (4 normal and 4 cleft lip and palate). The observations of histologic serial sections were undertaken in six fetus head and neck specimens on coronal, transverse and sagittal direction.

RESULTSThe palatopharyngeus with three components of pharyngeal origins and two heads of velar insertions contributes the continuity between the velum and lateral pharyngeal wall and the bulk of muscle fibers were extended to the posterior tonsilar pillars with (27.58 +/- 6.73) mm length and (34.1 +/- 10.50) mm2 section area. The muscles were supplied dominantly from the branches of ascending pharyngeal artery and tonsilar artery and partly from the branches of ascending palatine artery and dorsal lingual artery. The muscles were innervated by the branches of pharyngeal plexus which focus on the level 10 mm to 25 mm below the hard palate and at the level of 15 mm below the hard palate there was at least one of the nerve branch entered the muscle.

CONCLUSIONThe palatopharyngeus muscle is not only a major musculature of lateral pharyngeal wall but also an important portion of the soft palate, participating the middle and posterior velum, which means that the muscle may play a significant effect in the velar function and pharyngeal wall movements. It is also a good donor site for palatopharyngeus flap. The sphincter pharyngoplasty has some influence to the blood supply and innervation of the muscles, which may result to blood reversion and denervation for the distal component of palatopharyngeal flap.

OBJECTIVETo investigate the changes of hair dermal papilla and its regulatory role in the growth cycle of the hair follicles.

METHODSSingle hair follicles were isolated from surgical specimens of human scalp and cultured in Williams E medium. The growth of the hair follicle was measured and the morphology and structure of the dermal papilla in the different growth cycles were observed continuously.

RESULTSThe hair follicle could grow in the medium for 12 days at the average growth rate of 0.2-0.3 mm/day. The flat and round dermal papilla lay at the bottom of the hair bulb in the telogen and anagen stages. In the hair follicle with accelerated growth, the dermal papilla became elongated, loosened, and closely adhered to the hair matrix. In the catagen stage the dermal papilla shrunk, and became separated from the hair matrix. A new hair bulb was regenerated when the hair follicle was transected at a low level. The hair follicle stopped growing after transection at a higher position.

CONCLUSIONThe hair dermal papilla is the essential for hair follicle growth, and plays an important role in regulating the hair growth cycle.

OBJECTIVETo determine and perform a correlation analysis of the contents of putrescine, cadaverine, and histamine in necrotic tissue, blood, and urine of patients with diabetic foot (DF).

METHODSTen patients with severe wet necrotizing DF hospitalized from January 2011 to January 2012 were assigned as group DF, and 10 orthopedic patients with scar but without diabetes or skin ulcer hospitalized in the same period were assigned as control group. Samples of necrotic tissue from feet of patients in group DF and normal tissue from extremities of patients in control group, and samples of blood and 24-hour urine of patients in both groups were collected, and the amount of each sample was 10 mL. Contents of putrescine, cadaverine, and histamine were determined with high performance liquid chromatography-mass spectrometry. The data got from the determination of blood and urine were processed with t test, and those from necrotic or normal tissue with Wilcoxon rank sum test. The correlation of contents of polyamines between necrotic tissue and blood, blood and urine were processed with simple linear regression analysis.

RESULTS(1) Contents of putrescine, cadaverine, and histamine in the necrotic tissue of group DF were (186.1 ± 26.8), (78.553 ± 12.441), (33 ± 10) mg/kg, which were significantly higher than those in normal tissue of control group [(2.2 ± 1.2), (1.168 ± 0.014), 0 mg/kg, with Z values respectively -3.780, -3.781, -4.038, P values all below 0.01]. The content of putrescine in necrotic tissue of group DF was significantly higher than those of cadaverine and histamine (with Z values respectively -3.780, -3.630, P values all below 0.01). (2) Contents of putrescine, cadaverine, and histamine in the blood of group DF were (0.075 ± 0.013), (0.022 ± 0.003), (0.052 ± 0.014) mg/L, and they were significantly higher than those in the blood of control group [(0.014 ± 0.009), (0.013 ± 0.003), (0.016 ± 0.008) mg/L, with t values respectively 6.591, 2.207, 3.568, P < 0.05 or P<0.01]. The content of putrescine in the blood of group DF was significantly higher than those of cadaverine and histamine (with t values respectively 13.204, 3.096, P values all below 0.01). (3) Contents of putrescine, cadaverine, and histamine in the urine of group DF were (0.735 ± 0.088), (0.450 ± 0.012), (0.1623 ± 0.0091) mg/L, and only the contents of putrescine and cadaverine were significantly higher than those in the urine of control group [(0.050 ± 0.014), (0.035 ± 0.007) mg/L, with t values respectively 3.270, 4.705, P<0.05 or P<0.01]. The content of putrescine in the urine of group DF was significantly higher than that of cadaverine (t = 6.686, P < 0.01). (4) There were significant and positive correlations in contents of putrescine, cadaverine, and histamine between necrotic tissue and blood in patients of group DF (with r values respectively 0.981, 0.994, 0.821, P values all below 0.01). There were no significant correlations in contents of putrescine, cadaverine, and histamine between blood and urine in patients of group DF (with r values respectively 0.150, 0.239, 0.177, P values all above 0.05).

CONCLUSIONSPutrescine, cadaverine, and histamine exist in the necrotic tissue of patients with DF in high concentrations, among which putrescine predominates. These polyamines can be absorbed into the blood through wound and excreted through the urine.

OBJECTIVETo study the regulatory effect of Ligustrazine Injection (LI) on the cellular immune function in patients undergoing autologous blood transfusion (ABT).

METHODSEnrolled were 60 patients scheduled for receiving selective lumbar surgery at the Department of Spinal Orthopedics, First Hospital Affiliated to Guangzhou University of Traditional Chinese Medicine during October 2009 to June 2010. They were equally randomized into two groups, the trial group and the control group. LI was given to patients in the trial group by intravenous dripping at the dose of 2 mg/kg 30 min before autologous blood collection. The LI (at the final concentration of 0.005%) was added in the heparin saline solution and the washing saline for recycle blood. No LI was given to patients in the control group. They received the same treatment of the trial group. The operation time, the amount of blood loss and blood transfusion were recorded. Patients' venous blood samples were collected for determining cytokines including interleukin-2 (IL-2), interleukin-10 (IL-10), interferon-gamma (IFN-gamma) by ELISA and calculating IL-2/IL-10 ratio before surgery (T1), 1 h (T2), 1 day (T3), and 5 days (T4) after ABT.

RESULTSThere was no statistical difference in the amount of blood loss and blood transfusion, the levels of IL-2, IL-10, IFN-gamma, or IL-2/IL-10 at T1 between the two groups (P>0.05). Compared with T1 of the same group, the level of IL-2 decreased at T(2-4), IL-10 increased and IL-2/IL-10 decreased at T(2-3) in the two groups. The level of IFN-gamma decreased at T(2-4), IL-2/IL-10 increased at T4, the level of IL-10 decreased at T4 in the control group (P<0.05, P<0.01). The level of IL-10 decreased at T4 in the trial group with statistical difference (P<0.05, P<0.01). Compared with the control group, the level of IL-2, IFN-gamma, and IL-2/IL-10 at T(2-4) were obviously higher in the trial group. But the IL-10 level was lower in the trial group than in the control group at T(2-4) (P<0.05, P<0.01).

CONCLUSIONThe application of LI in ABT had regulatory effects on the balance of cytokines.

OBJECTIVETo construct a recombinant adenoviral vector carrying HBcAg-HSP70 chimeric gene by homologous recombination in bacteria and to detect its expression in vitro.

METHODSHeat shock protein 70 gene from Mycobacterium tuberculosis were amplified by PCR and were cloned to adenoviral shuttle plasmid pAdTrack-CMV-HBsAg. Then the resultant pAdTrack-CMV-HBsAg-HSP70 was cotransfected into BJ5183 bacteria with the plasmid pAdeasy-1. The adenoviral plasmid carrying HBsAg-HSP70 gene (pAd-HBsAg-HSP70) was generated with homologous recombination in bacteria and the adenoviruses were produced in 293 cells. Several kinds of mammal cells (293 cells and Vero cells) were infected with adenoviruses and the expression of HBsAg-HSP70 was detected by RT-PCR and ELISA in vitro.

RESULTSThe adenoviral plasmids pAd-HBsAg-HSP70 were obtained by selection for kanamycin resistance and confirmed by restriction endonuclease Pac analyses. The recombinant adenoviruses Ad-HBsAg-HSP70 were packaged successfully in 293 cells. The titer of Ad-HBsAg-HSP70 was up to 2 x 10(12) pfu/L after the second passage of proliferation in 293 cells. HBsAg and HSP70 were expressed efficiently in mammal cells after infection.

CONCLUSIONThe recombinant adenoviruses expressing HBsAg and HSP70 were constructed successfully which can be used further in study of gene therapy for HBV.

OBJECTIVETo study mRNA expression levels of main hematopoietic growth factors in bone marrow mesenchymal stem cells (BM-MSC), and to compare effect on mRNA expression levels treated by ginseng polysaccharide and ginsenoside.

METHODSRelative quantification real-time polymerase chain reaction (RT-PCR) was used to observe mRNA expression levels of IL4, Csf2, Kitlg, Csf1, IL6, Lif, Csf3, IL11, Epo, and IL3, etc. in rat BM-MSC treated with ginseng polysaccharide (20 microg/mL) or ginsenoside (20 microg/mL) at 12, 24, and 36 h.

RESULTSIL4 and Csf2 mRNA expressions were not detected. Relative expression of Kitlg, Csf1, IL6, Lif, Csf3, IL11, Epo and IL3 mRNA ranked in an attenuating order when compared with Gapdh mRNA. mRNA expression of Epo and IL3 was not significantly changed at any time point by treatment of ginseng polysaccharide or ginsenoside in rat BM-MSC (P > 0.05). mRNA expression of Csf1, IL6, Lif, Csf3 and IL11 were significantly enhanced at 12 and 36 h by treatment of ginseng polysaccharide (P < 0.05) and that of Csf1, IL6, Lif, Csf3, and Kitlg were significantly enhanced at 24 h in rat BM-MSC (P < 0.05). The enhanced mRNA expression was Csf3 at 12 h, Csf3, IL6 and Lif at 24 h, and Csf3, IL6, Lif, IL11, and Kitlg, respectively at 36 h by treatment of ginsenoside in rat BM-MSC.

CONCLUSIONSThe enhancement of ginseng polysaccharide was stronger than that of ginsenoside on mRNA expression of hematopoietic growth factors in the initial stage. As time went by, the enhancement of ginsenoside gradually increased and exceeded that of ginseng polysaccharide.
