OBJECTIVETo compare the clinical therapeutic effects differences between acupuncture at Suliao (GV 25) and Shuigou (GV 26) on promoting regain of consciousness from coma in severe craniocerebral injury.
METHODSBased on regular emergency treatments of neurosurgery, eighty-two cases of craniocerebral injury who were under stable condition were randomly divided into an observation group (42 cases) and a control group (40 cases). Suliao (GV 25) was selected as main aupoint, while Laogong (PC 8) and Yongquan (KI 1), etc. were selected as adjuvant acupoints and Neiguan (PC 6), Sanyinjiao (SP 6), Yifeng (TE 17) and Wangu (GB 12), etc. were selected as matching acupoints in the observation group where a strong needle manipulation was applied to improve the regain of consciousness. The main acupoint of Shuigou (GV 26) along with identical adjuvant acupoints and matching acupoints in the observation group were selected in the control group with identical strong needle manipulation. The treatment was given once a day in both groups, five times per week and ten times were considered as one session. The immediate clinical symptoms after acupuncture at Suliao (GV 25) and Shuigou (GV 26) were observed as well as Glasgow coma scale (GCS) before the treatment, after 45 days and 90 days of treatment to assess the resuscitation time and rate. Also the clinical efficacy was compared between both groups.
RESULTSThe occurrence rate of sneezing reflex was 85.7% (36/42) in the observation group, which was higher than 25.0% (10/40) in the control group (P < 0.01). The average resuscitation time was (64.6 +/- 19.4) days in the observation group, which was obviously shorter than (73.8 +/- 14. 6) days in the control group (P < 0.05). The resuscitation rate was 88.1% (37/42) in the observation group, which was similar to 75.0% (30/40) in the control group (P > 0.05). Compared before the treatment, GCS were both improved after the treatment in two groups (both P < 0.01). The 90-day GCS was 9.52 +/- 2.32 in the observation group, which was superior to 8.47 +/-2.14 in the control group (P < 0.05). The curative and markedly effective rate was 45.2% (19/42) in the observation group, which was superior to 22.5% (9/40) in the control group (P < 0.05).
CONCLUSIONThe effect of acupuncture at Suliao (GV 25) on improving regain of consciousness from coma in severe craniocerebral injury is positive. It could specifically improve sneezing reflex and stimulate respiratory center, which has more obvious effect than acupuncture at Shuigou (GV 26).

OBJECTIVETo assess the effect of local and intravenous transplantation of adipose tissue-derived stem cells (ADSCs) in promoting soft tissue wound healing in rats.
METHODSADSCs isolated from the adipose tissues of SD rats were cultured in vitro, and the third-passage cells were identified for their capacity of multipotent differentiation. Eighteen SD rats with 1.8 cm² dorsal full-thickness soft tissue defects (0.5 cm deep) were randomized into 3 groups to receive injection of 3.0×10⁶ DiI-labeled ADSCs via the tail vein, local injection of the cells at the wound site, or injection of saline (control). The wound healing was evaluated on days 3, 7, 11, and 14 postoperatively. On day 24 after the injury, tissue samples at the wound site were collected for fluorescent microscopy and HE staining.
RESULTSThe ADSCs obtained were capable of adipogenic, osteogenic, and neurogenic differentiation in vitro. ADSCs transplantation significantly promoted wound healing as compared to the control group. Obvious wound contracture was observed in the local injection group on day 3 and in the intravenous injection group on day 7. Fluorescence microscopy revealed DiI-positive cells in the healing wound, and HE staining showed a greater tissue thickness at the wound in the two ADSCs transplantation groups. Compared to the control group, the two ADSCs transplantation groups showed more gland-like structures and better neovascularization at the wound.
CONCLUSIONADSCs can significantly promote wound healing in rats, and local injection of ADSCs allows more rapid and obvious wound healing than tail veil injection of the stem cells.

OBJECTIVETo investigate the effects of ARNT2 on invasion and migration of HCCLM6 cells.
METHODSFour short hairpin oligos targeting to ARNT2 were s cloned into the pLVTHM vector. Lentiviral vectors shRNA-ARNT2i, pCMV-dR8.74 and pMD2G were cotransfected into 293T cells using Lipofectamine 2000. HCCLM6 was infected with virus supernatant. ARNT2 mRNA and protein expressions were detected using quantitative Real time-PCR and Western blot, respectively. The invasion and migration of HCCLM6 cells were evaluated using wound healing assay and cell invasion assay in vitro. Statistical analysis was performed with SPSS 16.0.
RESULTSThe relative mRNA levels of ARNT2 were 0.154+/-0.024, 0.860+/-0.145, 1.004+/-0.009 in shRNA-ARNT2i virus infected HCCLM6 cells, mock-infected cells and control vector virus infected cells (F = 113.14, P more than 0.01). The expression of ARNT2 at protein level was 16.45+/-1.6, 44.56+/-2.07 in the HCCLM6 cells infected with shRNA-ARNT2i virus and negative control vector virus, respectively (t = 18.58, P less than 0.01). The scrape wound of HCCLM6 cells infected with shRNA-ARNT2i virus healed faster than cells infected with control vector virus or mock-infected cells. The number of cells invading through Matrigel was higher in the HCCLM6 cells infected with shRNA-ARNT2i virus (13.25+/-1.04) than that in mock-infected HCCLM6 cells and the HCCLM6 cells infected with negative control vector virus (6.50+/-2.56, 6.75+/-2.05) (F = 29.645, P less than 0.01).
CONCLUSIONInhibition of ARNT2 gene promotes the invasion and migration of HCCLM6 cells.

OBJECTIVETo investigate the effect of adipose stromal vascular fraction cells (SVFs) on the survival rate of fat transplantation.
METHODS0. 5 ml autologous fat tissue was mixed with: 1) Di-labeled autologous SVFs ( Group A); 2) Di-labeled autologous adipose-derived stem cells (ASCs) (Group B); 3)Complete DMEM (Group C). And then the mixture was injected randomly under the back skin of 14 rabbits. The transplanted fat tissue in three groups was harvested at 6 months after implantation. Wet weight of fat grafts was measured for macroscopic aspects. After HE staining, blood vessel density, viable adipocytes and fibrous proliferation were counted respectively for histological evaluation. Trace of DiI-labeled ASCs in vivo was detected by fluorescent microscope.
RESULTSThe wet weight of fat grafts in group A (291.0 +/- 72.1) mg and group B (269.3 +/- 67.3) mg was significantly higher than that in group C (177.8 +/- 60.0) mg, but the difference between Group A and Group B was not significant. Histological analysis revealed that the fat grafts in group A and B was consisted predominantly of adipose tissue with less fat necrosis and fibrosis, compared with the fat grafts in group C. The grafts in both group A and B had significantly higher capillary density than those in the control group. Part of vascular endothelial cells were observed to origin from ectogenic DiI-labeled SVFs and ASCs.
CONCLUSIONSThe autologous isolated SVFs has a similar effect as autologous cultured ASCs to improve the survival rate of fat transplantation. And the former is more practical and safe, indicating a wide clinical application in the future.

OBJECTIVETo compare the number of harvested perisplenic hilar lymph nodes by laparoscopy-assisted total gastrectomy (LATG) and conventional open total gastrectomy (OTG) for advanced upper and middle gastric cancer.
METHODSThree hundred twelve patients with advanced gastric cancer treated in a single institution between Sept 2008 and Jan 2011 were included in this study. They were divided into two groups: the LATG group and OTG (D2) group. All the surgical operations were performed by one surgeon or under his supervision. The lymph node clearance outcomes of the patients treated by those two surgical procedures were analyzed.
RESULTSThe harvested lymph node numbers of the two groups were (29.57 ± 9.62) and (29.38 ± 11.22) respectively, statistically with no significant difference (P = 0.875). The numbers of lymph node dissected around the splenic area in the LATG group and OTG group (Section 10, 11 group) were (2.01 ± 1.34) and (1.33 ± 1.11), respectively, indicating a significant difference (P = 0.000). The numbers of lymph nodes dissected around the celiac region (Section 7, 8, 9, 11p and 12a(2) group) were (7.90 ± 3.41) and (7.22 ± 2.65), respectively, with a non-significant difference (P = 0.050). There were also no significant differences while comparing with the numbers of lymph nodes dissected in the cardiac area (group 1, 2), pyloric region (5, 6 group) and the greater and lesser omentum area (group 3 and 4) between the two groups (P = 0.605, P = 0.248, P = 0.262).
CONCLUSIONShort-term results of this study indicate that laparoscopy-assisted total gastrectomy (D2) is better than conventional open surgery in perisplenic hilar lymph node dissection.
