OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.

METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.

RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.

CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

OBJECTIVETo evaluate the intervention effect of Feiji Recipe (FJR) on tumor immune escape.

METHODSIn the prospective randomized control study, 60 cases of middle stage and advanced non-small cell lung cancer (NSCLC) with qi-yin deficiency syndrome were randomly assigned to the treatment group and the control group, 30 in each group. The levels of CD+ CD25+ Tr, interleukin-10 (IL-10), vascular endothelial growth factor (VEGF), sCD44v6 and transforming growth factor-beta1 (TGF-beta1) of peripheral blood were observed before and after treatment, and the clinical efficacy of FJR was evaluated depending upon the changes in tumor size, Karnofsky Performance scoring (KPS) and TCM syndrome.

RESULTS(1) The levels of CD4+ CD2+Tr, VEGF, sCD44v6, TGF-beta1, and IL-10 decreased, in the treatment group as compared with those in the control group, respectively. (2) The stabilization rate of tumor in the treatment group was superior to that in the control group (78.26% vs 50.00%, P < 0.05). (3) The stabilization rate of KPS increasing in the treatment group and the control group was 76.67% and 43.33% respectively, suggesting the improvement of KPS in the treatment group was superior to that in the control group (P < 0.01). (4) Improvement in TCM qi-yin deficiency syndrome was more significant in the treatment group than that in the control group.

CONCLUSIONFJR can stabilize the tumor body, improve the clinical symptoms of middle stage and advanced NSCLC with qi-yin deficiency syndrome, promote patients' quality of life, and is effective in recovering immuno-surveillance and intervening immune escape of lung cancer through multi-pathway to enhance the clinical therapeutic efficacy.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

BACKGROUNDThe mechanisms underlying postoperative pain remain unclear. Neurotransmitters of excitatory and inhibitory amino acids play an important role in the transmission and modulation of pain in the spinal dorsal horn. This study aimed to investigate the changes of release of excitatory and inhibitory amino acids in the spinal cord during postoperative pain and to provide a novel theoretical basis for postoperative pain management.

METHODSLoop microdialysis catheters were implanted subarachnoidally via the atlanto-occipital membrane in 16 healthy Sprague-Dawley rats. All rats without neural deficits were divided into two groups, Group A and Group B, following 5 days of recovery. The tubes for microdialysis were connected and 25 microl microdialysate sample for baseline value was collected after one-hour washout in each rat. A plantar incision in the right hind paws of rats in Group A were performed under 1.2% isoflurane. All rats in Group B were only anesthetized by 1.2% isoflurane for the same duration. The microdialysate samples were collected at 3 hours, 1 day, 2 days and 3 days after the incision (or isoflurane anesthesia in Group B) in both groups. The cumulative pain scores were also assessed at the above time-points. The amino acids in the microdialysate samples were tested using high performance liquid chromatography.

RESULTSWithin Group A, the release of aspartate and glutamate at 3 hours after the incision was significantly higher than the baseline values and the release of glycine at 1 day after the incision significantly increased compared with the baseline values (P < 0.01). Within Group B, the release of neurotransmitters at each time point had no significant difference compared with the baseline values (P > 0.05). The release of aspartate and glutamate at 3 hours after the incision in Group A was significantly higher than that in Group B (P < 0.01). The release of glycine at 1 day after the incision in Group A significantly increased compared with Group B (P < 0.01). The cumulative pain scores at 3 hours, 1 day and 2 days after the incision in Group A were significantly higher than those in Group B (P < 0.01).

CONCLUSIONSThe release of the excitatory amino acids occurs in the early phase of postoperative pain and might not be involved in the maintenance of pain in a rat model of incision pain. The release of inhibitory glycine lagged behind the excitatory amino acids. The implication of inhibitory glycine release remained to be established further.

The laser-induced breakdown spectroscopy (LIBS) was applied to perform a qualitative elementary analysis on four precious Tibetan medicines, i. e. Renqing Mangjue, Renqing Changjue, 25-herb coral pills and 25-herb pearl pills. The specific spectra of the four Tibetan medicines were established. In the experiment, Nd: YAG and 1 064 nm-baseband pulse laser were adopted to collect the spectra. A laser beam focused on the surface of the samples to generate plasma. Its spectral signal was detected by using spectrograph. Based on the National Institute of Standard and Technology (NIST) database, LIBS spectral lines were indentified. The four Tibetan medicines mainly included Ca, Na, K, Mg and other elements and C-N molecular band. Specifically, Fe was detected in Renqing Changjue and 25-herb pearl pills; heavy mental elements Hg and Cu were shown in Renqing Mangjue and Renqing Changjue; Ag was found in Renqing Changjue. The results demonstrated that LIBS is a reliable and rapid multi-element analysis on the four Tibetan medicines. With Real-time, rapid and nondestructive advantages, LIBS has a wide application prospect in the element analysis on ethnic medicines.
