Advances in mechanism and application of the heating effect in breeding of microorganism are reviewed in this paper. Heat produces mutagenesis effect and screening effect. Heating mutagenesis effect is occurred through the substitution of G-C base pair induced by heat, and heating screening effect produces higher forward mutation rate induced by other mutagens.

Litsea cubeba is one of aromatic medicinal plant belonging to family Lauraceae. The roots, stems and fruits of L. cubeba have been widely applied as folk medicines in some districts in China for relieving rheumatism and cold, regulating Qi (meridian) to alleviate pain. Previous studies revealed that this species contains major alkaloids, in specific aporphines, and minor flavonoids, lignans as well. Related pharmacological investigations demonstrated its activities and clinical applications on cardiovascular diseases, anti-cancer, against rheumatoid arthritis, relieving asthma and anti-allergic effects, as anti-oxidants, and so on. As an effort for further exploration of this bioactive ingredients and potential drug development, this paper summarizes most phytochemical and pharmacological results. Further, future prospects are also included.

A phytochemical investigation on the roots and stems of Litsea cubeba led to the isolation of seven isoquinolone alkaloids. By spectroscopic analysis and comparison of their 1H and 13C-NMR data with those in literatures, these alkaloids were identified as (+)-norboldine (1), (+)-boldine (2), (+)-reticuline (3), (+)-laurotetanine (4), (+)-isoboldine (5), (+)-N-methyl-laurotetanine (6), and berberine (7), respectively. Among them, 7 was isolated from the genus for the first time. The evaluation of these compounds showed weak anti-inflammatory activity against NO production in RAW 267.4 and BV-2 cells.

?AlM: To investigate repeatability and accuracy of a latest Keratograph for evaluating the tear film stability and to compare its measurements with that of traditional examination methods.
?METHODS: The results of noninvasive tear film break-up time ( Nl-BUT ) including the first tear film break-up time ( BUT-f ) and the average tear film break-up time ( BUT - ave ) were measured by Keratograph. The repeatability of the measurements was evaluated by coefficient of variation ( CV ) and intraclass correlation coefficient ( lCC) . Wilcoxon Signed-Rank test was used to compare Nl-BUT with fluorescein tear film break-up time ( FBUT) to confirm the correlation between Nl-BUT and FBUT, Schirmer l test values. Bland-Altman analysis was used to evaluate consistency.
?RESULTS: The study recruited 48 subjects ( 48 eyes ) (mean age 38. 7±15. 2 years). The CV and lCC of BUT-f were respectively 12. 6% and 0. 95, those of BUT-ave were 9. 8% and 0. 96. The value of BUT-f was lower than that of FBUT. The difference had statistical significance ( 6. 16±2. 46s vs 7. 46±1. 92s, P<0. 01). There was significant positive correlation between Nl-BUT and FBUT, Schirmer l test values ( P< 0. 01 ). The scope of 95% limits of agreement (LoA) was 4. 46s in BUT-f and FBUT, while the scope of LoA was 3. 64s in BUT-ave and FBUT.
?CONCLUSlON: Keratograph can provide Nl-BUT data that has a better repeatability and reliability, which has great application prospects in diagnosis and treatment of dry eye and refractive corneal surgery.

Objective To observe the effect of breathing exercise based on core strength training on nonspecific low back pain (NLBP). Methods From January to June, 2017, 60 patients with NLBP were randomly divided into control group (n=30) and ob-servation group (n=30). The control group accepted core strength training, and the observation group accepted breathing exercise in addition, for four weeks. They were assessed with Visual Analogue Scale (VAS) and Oswes-try Disability Index (ODI) before and after treatment, and their efficiency was compared. Results The scores of VAS decreased in both groups after treatment (t>4.173, P<0.001), and the scores of ODI de-creased in the observation group (t=3.875, P<0.01). The scores of both VAS and ODI were less in the observa-tion group than in the control group (t>2.595, P<0.05). The efficiency was better in the observation group than in the control group (χ2=3.874, P<0.05). Conclusion Breathing exercise based on core strength training can further improve function and relieve pain in patients with NLBP.

OBJECTIVE Metastasis-associated in colon cancer-1 (MACC1) is an oncogene that has been newly identified. It promotes tumor proliferation and invasion via the MET pathway. Our study investigated the effects of Saikosaponin-b(SS-b) on the proliferation and apoptosis of HepG2 cells and its regulation on MACC1/c-Met/Akt signaling pathway. METHODS HepG2 cells were treated with SS-b (10-800 g·L-1) for 48 h in vitro. The CCK-8 assay was used to assess cell proliferation, and cell apoptosis was determined by Hoechst33258 staining, AnnexinⅤ/PI staining and caspase 3 assay. RT-PCR was used to examine the expression of MACC1, c- MET and hepatocyte growth factor (HGF) mRNA. MACC1 protein was detected by Western blot and immunohistochemistry. The protein expressions of p-c-MET, c-MET, p-AKT, AKT, p-BAD, BAD were measured by Western blot. RESULTS SS-b inhibited the growth of HepG2 cells in dose-dependent way and induced cell apoptosis significantly. HepG2 cells showed karyopyknosis, fragmentation and fluorescence highlight in SS-b treatment group. FCM results showed that apoptosis rate of HepG2 cells increased with SS- b concentration. The immunofluores?cence results showed that the MACC1 expression decreased significantly in HepG2 cells treated with SS-b. The expression levels of MACC1, c-MET and HGF mRNA in HepG2 cells were significantly inhibited by SS-b. SS-b also significantly decreased the protein expressions of MACC1, p-c-MET and p-AKT while increased the expression of p-BAD and caspase 3 in HepG2 cells(P<0.05). CONCLUSION SS-b inhibited the proliferation and induced the apoptosis of HepG2 cells by targeting the MACC1/c-Met/Akt signaling pathway.

OBJECTIVETo evaluate the short-term and long-term curative effect of microvascular decompression sensory root of trigeminal nerve combing (MVD + SRTNC) by post-sigmoid approach as well as the complications in these operations.

METHODSThe data from 138 idiopathic trigeminal neuralgia (TN) patients treated with MVD + STRNC that followed up 33 months to 58 months was analyzed.

RESULTSImmediate relief from pain occurred in 136 patients (98.6%). On Kaplan-Meier analysis, cumulative proportion effectiveness at the end of 25 months decreased to 91.4%, and 85.8% from 49 months to 58 months. There were cases of 63.83% and 19.15% with slight and midrange hypoesthesia after surgery but majority recovered at the end of 3-58 months (P < 0.01). No serious hypoesthesia occurred. The complications including leakage of cerebrospinal fluid, herpes and headache caused by high intracranial pressure, were observed in 4 cases (2.90%), 36 cases (26.09%) and 3 cases (2.17%), respectively. Two cases (1.43%) died of cerebral hemorrhage.

CONCLUSIONSThe proposed surgical strategy of standard MVD plus sensory root of trigeminal nerve combing was a good strategy option for TN, but It was important for surgeons to think highly of the risks of the surgery.
