OBJECTIVETo investigate the incidence of the temporary and permanent sensory disturbance of the inferorbital nerve (ION) after Le Fort I osteotomy.

METHODSThirty patients with 60 inferorbital nerves were examined preoperatively, 1 week, 1 month, 3 months and 6-months after the operation of the Le Fort I osteotomy by using sharp-blunt testing, 2-point discrimination, electric pain response test (ZGK-1 electrometer).

RESULTSThe incidence of the temporary nerve impairment was 75% (45 of 60) and the obvious recovery was found after 1 to 3 months after the operation. No permanent sensory disturbance was found in the patients.

CONCLUSIONSThe inferorbital nerve injury after Le Fort I osteotomy is usually temporary and the sensory recovery was in 1 to 3 months after the operation.

Ferroptosis is distinct from apoptosis,autophagy,necrosis,cornification and other cell deaths from morphological,biochemical as well as genetic aspects.Ferroptosis plays a critical role in neurological diseases and cancers.Neurological diseases,such as Alzheimer's disease,Parkinson's disease,Huntington's disease,stroke,periventricular leukomalacia and so on,are characterized by multiple etiologies and mechanisms,and are potentially correlated with ferroptosis.Based on the recent researches on ferroptosis and neurological diseases,this review investigates ferroptosis and its role in neurological diseases.

OBJECTIVETo investigate the safety and efficacy of fast track surgery (FTS) management in gastric cancer undergoing D2 gastrectomy.

METHODSEighty gastric cancer patients undergoing D2 gastrectomy were recruited prospectively. Patients were assigned to receive FTS management (n = 40) or conventional perioperative care (n = 40). The FTS care included shorten preoperative fasting time, no nasogastric decompressing tubes and abdominal drainage placed, early postoperative oral feeding, multimodal analgesia, and early mobilisation. The length of postoperative hospital stay, medical cost, nutritional status, gut function, and postoperative complications in the two groups were recorded and compared.

RESULTSFTS group was associated with a significantly shorter postoperative hospital stay compared with conventional care group [(5.6 +/- 1.3) d vs. (9.4 +/- 1.9) d, P < 0.05]. Medical cost was less [(18 620 +/- 2360) Yuan vs. (20 370 +/- 2440) Yuan, P < 0.05] and duration of intravenous infusion [(3.5 +/- 1.4) d vs. (5.8 +/- 1.9) d, P < 0.05] was also shorter. First passage of flatus was earlier in FTS group than in conventional care group [(4.3 +/- 0.4) d vs. (5.5 +/- 0.9) d, P < 0.05]. Loss of body weight in the postoperative period was less in FTS group [(3.2 +/- 0.8) kg vs. (4.3 +/- 1.6) kg, P < 0.05]. There was no difference in morbidity or mortality between the two groups.

CONCLUSIONFTS in D2 gastrectomy is safe and efficient, and it can shorten postoperative hospital stay and hasten return of gut function.

Neural stem cells (NSCs) posse the specialty of tumor tropism and be able to migrate specifically to tumor cells. NSCs are also cross the blood brain barrier. NSCs keep in touch with tumor cells preferentially under the tumor microenvironment, and surround the target cells. Based on these characteristics, NSCs can be used as a carrier for therapeutic virus, enzymes/prodrugs, genes or suicide genes, etc. which are selectively delivered to the glioma cells. NSCs may be modified by a variety of different genes to establish a reliable, safe and effective therapy for glioma.

Genus Lilium plants contain a variety of steroidal saponins, so far at least 82 steroidal saponins have been found in the bulbs of Lilium species, including 13 spirostanol saponins (1-13), 39 isospirostanol saponins (14-52), 7 pseudospirostanol saponins (53-59), and 23 furostanol saponins (60-82). Studies have showed that these steroidal saponins exhibit a wide range of pharmacological activities, including antitumor, antibacterial, antiinflammatory, antioxidant, antidepressant, hepatoprotective, hypoglycemic, sedative-hypnotic effect, and inhibition of cAMP phosphodiesterase and Na⁺-K⁺ ATP, et al. This paper has classified and summarized the 82 steroidal saponins isolated and identified from the bulbs of Lilium species and their correlative biological activities. Also, their structural characteristics and structure-activities relationship have been discussed, which could provide references for further research and application development of Lilium plants.

The potential role of total saponins extracted from Lilium lancifolium bulbs (TSLL) on the proliferation, apoptosis, migration and invasion of human lung cancer A549 cells and its possible mechanism were discussed. Effect of TSLL on proliferation of A549 cells were detected by CCK-8, clone formation assay and EdU staining. Effect of TSLL on apoptosis morphology of A549 cells was observed by fluorescence microscope using Annexin V/PI double staining and Hoechst 33342 staining. Effect of TSLL on cell migration and invasion was detected by Transwell migration test and Transwell invasion test, respectively. Western blot was used to detect TSLL on the expression change of intracellular associated proteins. Results showed that TSLL intervention in A549 cells within 24, 48 or 72 h significantly inhibited cell growth, and its IC₅₀values were about 229, 173 and 71 mg·L⁻¹, respectively. TSLL significantly reduced the clone formation rate of A549 cells and decreased the DNA synthesis rate of A549 cells in a concentration dependent manner. TSLL induced A549 cells apoptosis and reduced the migratory behavior of A549 cells. TSLL decreased invasion of A549 cells to the artificial basement membrane. The expression level of intracellular PCNA and the ratio of Bcl-2/Bax protein were down-regulated and procaspase 3 was activated. In addition, TSLL had no obvious effect on epithelial mesenchymal transition (EMT) related marker proteins E-cadherin and vimentin expression. The above results indicated that TSLL possess inhibitory effects against proliferation, migration and invasion of lung cancer A549 cells and apoptosis-induced effect. The anti-proliferation effect of TSLL is very likely by inhibiting intracellular DNA synthesis through reducing the expression of PCNA in lung cancer cells. And the apoptosis induction of TSLL on lung cancer cells is associated with the regulation of Bcl-2 and Bax proteins expression. Nevertheless, there is no incontestable correlation between anti-invasion and metastasis effects of TSLL and EMT in lung cancer cells.
