Objective To evaluate the safety and feasibility of laparoscopic left hepatectomy in patients with primary hepatic carcinoma. Methods Retrospective analysis was conducted in clinical data of left hepatectomy from 2007 to 2014,including 47 cases of laparoscopic hepatectomy and 46 cases of open hepatectomy. The intraoperative and postoperative data of the two surgical methods were compared to evalu-ate whether laparoscopic left hepatectomy is safe and feasible. Results The tumor size were bigger in the open hepatectomy [(56. 57 ± 24. 56) mm vs. (64. 11 ± 33. 39) mm,P=0. 218]. The laparoscopic left hepatectomy resulted in shorter operation time [(217. 53 ± 60. 22) min vs.(306.80±119.91)min],andtherewasasignificantlydifference(P<0.05).Theintraoperativebloodlosswerelesserinthelaparo-scopic left hepatectomy [(350. 21 ± 197. 98) mL vs. (556. 74 ± 471. 41) mL],and there was a significantly difference (P<0. 05). The lap-aroscopic left hepatectomy had a smaller intraoperative blood transfusion rate (12. 8% vs. 32. 6%,P<0. 05). The length of ICU stay,time for gastroentestinal function recovery, postopetative hospital stay were shorter than those of open left hepatectomy (P<0. 05). There was no significant difference of postoperative complication rate between them (14. 9% vs. 23. 9%,P=0. 271). The survival rates of 1-and 3-year after operation in patients with laparoscopic left hepatectomy were 91. 5% and 83. 0% respectively,while 84. 8% and 76. 1% in patients un-derwent open hepatectomy. The tumor-free survival rates 1-and 3-year after operation were 74. 5% and 59. 6% in patients with laparoscopic left hepatectomy respectively,while 65. 2% and 54. 3% in patients underwent open hepatectomy. Conclusion Laparoscopic left hepatectomy for primary hepatic carcinoma is safe and feasible. Laparoscopic left hepatectomy could be a consideration as the standard surgical methods for hepatic carcinoma.

To establish a method for detecting microdialysis recovery of tetramethylpyrazine (TMP) and ferulic acid (FA) and investigating the influencing factors, providing the basis for further in vivo microdialysis experiments. The concentration of FA and TMP in dialysates were determined by high pressure liquid chromatography ( HPLC) and probe recovery were calculated respectively. The influence of the flow rates, medium concentration, temperature and in vivo probe stability on the recovery of FA and TMP were investigated by using concentration difference method (incremental method and decrement method). The recovery obtained by incremental method were similar to by decrement method. The in vitro recovery rate of FA and TMP decreased with the increase of 1-2.5 μL min(-1), and increased obviously with the temperature of 25-42 degrees C under the same conditions. The concentration of FA and TMP had no obvious effect on the probe recovery under the same flow rate. In addition, the recovery of TMP and FA remained stable and showed similar trends under the condition of four concentration cycles, indicating that the intra day reproducibility of the concentration difference method was good. The recovery of brain microdialysis probes in vivo 8 h maintained a relatively stable, but certain differences existed between different brain microdialysis probes, demonstrating that each probe was required for recovery correction in vivo experiment. Microdialysis sampling can be used for the local brain pharmacokinetic study of FA and TMP, and retrodialysis method can be used in probe recovery of FA and TMP in vivo.

Objective To investigate the therapeutic effect of dense-packing auto hair grafting technique on the restoration of seborrheic alopecia. Methods With local anesthesia, a scalp strip was harvested from the back of the head. Under operating microscope (Various graft was created from the scalp strip, including micro-grafts with 1-2 hairs, mini-grafts with 3-4 hairs and sliver graft with 5-6 hairs. In the alopecia recipient area, micro slots were made with a small triangle-edged needle for the micro-grafts,mini slits were made with mini blade for the mini-grafts and foramen ovale were made with a slot punch. The grafts were then implanted into these holes. Results 32 cases of seborrheice alopecia were treated with the above mentioned technique from March 2007 to July 2009. Postoperative following up for 12-24 month showed that the grafted hairs were growing well with average 90 % survival of the hair. 81 % of the patients obtained satisfactory results with only one stage operation. Six patients needed the second operation to improve the appearance. All of the patients were satisfied with the appearance. Conclusions The dense-packing hair grafting technique with various grafts not only saves time of operation, but also obtains dense grafted hair and well appearance. The results are satisfactory to most patients with only one stage operation.

OBJECTIVE:
To explore the relationship between degradation of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA in the mouse liver and postmortem interval (PMI).
METHODS:
Sixty NIH mice were sacrificed by cervical dislocation and suffocation, and then placed into 10 degrees C and 25 degrees C temperature-controlling systems. The changes of GAPDH mRNA in the liver were detected by two-step fluorimetric reverse transcriptase polymerase chain reaction (RT-PCR) technique and nucleic acids protein cryoscope from 0 to 48 h postmortem.
RESULTS:
In the mouse liver, the amplification products of GAPDH mRNA could be examined within 48 h postmortem in 10 degrees C temperature-controlling system and within 36 h postmortem in 25 degrees C temperature-controlling system. The amplification products showed a decreasing tendency.
CONCLUSION
Degradation of GAPDH mRNA in the mouse liver is negative correlation with PMI. GAPDH mRNA could be a new marker for estimation of PMI.

OBJECTIVETo determine whether an adenoviral construct containing bone morphogenetic protein-4 (BMP-4) gene can be used for lumbar spinal fusion.
METHODSTwelve New Zealand white rabbits were randomly divided into two groups, 8 in the experimental group and 4 in the control group. Recombinant, replication-defective type 5 adenovirus with the cytomegalovirus (CMV) promoter and BMP-4 gene (Ad-BMP-4) was used. Another adenovirus constructed with the CMV promoter and beta-galactosidase gene (Ad-beta-gal) was used as control. Using collagen sponge as a carrier, Ad-BMP-4 (2.9 multiply 10(8) pfu/ml ) was directly implanted on the surface of L(5)-L(6) lamina in the experimental group, while Ad-beta-gal was implanted simultaneously in the control group. X-ray was obtained at 3, 6, and 12 weeks postoperatively to observe new bone formation. When new bone formation was identified, CT scans and three-dimensional reconstruction were obtained. After that, the animals were killed and underwent histological inspection.
RESULTSIn 12 weeks after operation, new bone formation and fusion were observed on CT scans in the experimental group, without the evidence of ectopic calcification in the canal. Negative results were found in the control group. Histological analysis demonstrated endochondral bone formation at the operative site and fusion at early stage was testified.
CONCLUSIONSIn vivo gene therapy using Ad-BMP-4 for lumbar posterolateral spinal fusion is practicable and effective.

OBJECTIVETo study the changes of extracellular glucose (Glu), lactate (Lac), and the ratio of lactate/pyruvate (L/P) in patients with traumatic brain injury under different body temperatures.
METHODSCatheters for microdialysis were punctured into the penumbra zone of injured brain tissue (INJ), relatively normal brain tissue (NOR), and abdominal subcutaneous tissue (ABD) respectively in 51 patients to collect the fluid. The perfusion rate was 0.3 microl/min and one tube of fluid was collected for each hour. The average collection time was (67.10 +/- 18.27) hours. Concentrations of Glu, Lac, and pyruvate (Pyru) in the fluid were analyzed using CMA microdialysis analyzer. Patients were divided into 7 groups according to their rectal temperature (RT) values, which were RT < 33.0 degrees C, 33.0-33.9 degrees C, 34.0-34.9 degrees C, 35.0-35.9 degrees C, 36.0-36.9 degrees C, 37.0-37.9 degrees C, and > or = 38.0 degrees C.
RESULTSThe concentration of Glu in ABD was significantly higher than that in the brain tissue (P < 0.05). The Glu in NOR were significantly higher and the highest in 33.0 degrees C compared with that in the INJ when RT < 36.0 degrees C (P < 0.05). The concentration of Lac in ABD was significantly lower than that in brain (P < 0.05). The Lac in NOR were much higher than that in INJ when RT < 35.0 degrees C or > or = 37.0 degrees C (P < 0.05). The ratio of L/P decreased along with the increase of body temperature (P < 0.001). The ratio of L/P significantly decreased in an order of INJ > ABD > NOR when RT was lower than 33.0 degrees C, which was changed to the order of NOR > INJ > ABD when RT was higher than 34.0 degrees C.
CONCLUSIONTreatment of hypothermia may play more protective role when RT were between 33-34 degrees C or 36-37 degrees C.
