Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.

OBJECTIVE:
To investigate the position change of the fibular bone after maxillary reconstruction by free fibular flap and to analyze the factors affecting the position change.
METHODS:
Patients who underwent maxillary reconstruction by free fibular flap in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from November 2012 to November 2016 were enrolled in this study. CT scans 1 week and 1 year postoperatively were collected and stored in DICOM format. The ProPlan CMF software was used to reconstruct the CT scans and separate the maxilla and each segment of the fibular flap. The Geomagic Control software was used to measure the long axis direction vector of each fibular segment. And the position change direction was recorded. The patients were divided into groups according to the use of the fibula or titanium plate to reconstruct the zygomaticmaxillary buttress.
RESULTS:
A total of 32 patients were enrolled. Among them, 21 were in the titanium plate group and 11 in the fibula bone group. The angle between the long axis of the fibular segment and the X axis in the X-Y plane was 95.65°±53.49° and 95.53°±52.77°, 1 week and 1 year postoperatively, and there was no statistical difference (P>0.05). The angle between the long axis of the fibular segment and the X axis in the X-Z plane was 96.88°±69.76° and 95.33°±67.42°, respectively, with statistical difference (P=0.0497). The angular changes of the long axis of the fibular segment in the titanium plate group and the fibular bone group were 3.23°±3.93° and 1.94°±1.78°, respectively, and the angular changes in the X-Z plane were 6.02°±9.89° and 3.27°±2.31°, respectively. There was no significant difference between the groups (P>0.05). The long axis changes of the fibular segment in the X-Y plane for reconstruction of the anterior alveolar, posterior alveolar, and buttress were 3.13°±3.78°, 2.56°±3.17°, and 5.51°±4.39°, respectively. There was a statistical difference (P = 0.023) between the posterior and buttress. In the X-Z plane, theses were 4.94°±4.75°, 5.26°±10.25°, 6.69°±6.52°, respectively. There was no statistical difference among the three groups (P>0.05). The main positional deviation directions of the titanium plate group and the fibular bone group were interior and superior sides, and there was no statistical difference between the two groups (P>0.05).
CONCLUSION
One year postoperatively, the position of the free fibular flap was changed compared with 1 week postoperatively. The position of the free fibular flap was mainly changed to the interior and superior sides.

OBJECTIVETo investigate the effect of curcumin (Cur) on radiosensitivity of nasopharyngeal carcinoma cell CNE-2 and its mechanism.
METHODThe effect of curcumin on radiosensitivity was determined by the clone formation assay. The cell survival curve was fitted by Graph prism 6. 0. The changes in cell cycle were analyzed by flow cytometry (FCM). The differential expression of long non-coding RNA was detected by gene chip technology. Part of differentially expressed genes was verified by Real-time PCR.
RESULTAfter 10 micro mol L-1 Cur had worked for 24 h, its sensitization enhancement ratio was 1. 03, indicating that low concentration of curcumin could increase the radiosensitivity of nasopharyngeal carcinoma cells; FCM displayed a significant increase of G2 phase cells and significant decrease of S phase cells in the Cur combined radiation group. In the Cur group, the GUCY2GP, H2BFXP, LINC00623 IncRNA were significantly up-regulated and ZRANB2-AS2 LOC100506835, FLJ36000 IncRNA were significantly down-regulated.
CONCLUSIONCur has radiosensitizing effect on human nasopharyngeal carcinoma CNE-2 cells. Its mechanism may be related to the changes in the cell cycle distribution and the expression of long non-coding IncRNA.

BACKGROUNDSeveral studies have shown that coronary stenting reduces the frequency of clinical and angiographic restenosis in patients with mild to moderate renal insufficiency. However, less is known about the long-term benefits of stent use in this population. This study was aimed to determine the impact of coronary stenting on extended (5 years) long-term outcomes of patients with chronic renal insufficiency.
METHODSThe study included 602 consecutive patients who underwent successful percutaneous coronary intervention with stenting. Renal insufficiency was defined as an estimated glomerular filtration rate < 60 ml x min(-1) x 1.73 m(-2). The major adverse cardiac events were compared for patients with (n = 160) and without (n = 442) renal insufficiency.
RESULTSAfter the third year of follow-up, nonfatal myocardial infarction and revascularization rates were significantly increased in patients with renal insufficiency compared with those without renal dysfunction (16.9% vs 7.7%, P = 0.001; 29.4% vs 15.8%, P < 0.001). In patients who had recurrent cardiovascular events, a significantly higher rate of de novo stenosis revascularization was found in patients with renal insufficiency than without renal insufficiency (57.7% vs 22.7%, P < 0.001), while there was no significant difference in target lesion revascularization between the groups (51.9% vs 43.6%, P = 0.323). Multivariate analysis demonstrated an independent impact of the presence of renal insufficiency on the major adverse cardiac events (hazard ratio: 1.488, 95% confidence interval: 1.051 - 2.106, P = 0.025) and de novo stenosis (hazard ratio: 5.505, 95% confidence interval: 2.151 - 14.090, P < 0.001).
CONCLUSIONSThe late major adverse cardiac events, after successful coronary stenting, is increased in patients with an estimated glomerular filtration rate < 60 ml x min(-1) x 1.73 m(-2). This might be associated with increased risk of de novo stenosis in this population.

Rheum franzenbachii (called Tudahuang in local) has some similarities with R. palmatum (rhubarb) collected by "China Pharmacopoeia" and is often used as a substitute of rhubarb. Can Tudahuang simply replace rhubarb in the application or whether is there difference between Tudahuang and rhubarb, and what is the difference it is important to verify the difference and understand its proper application in the field of clinical practice. In this paper, we discussed the differences of the two herbs from the views of chemistry, efficacy and toxicity based on the author's previous research work as well as literatures, by using the major role of the rhubarb "diarrhea" as the basic point. The analysis result showed that the role of diarrhea Tudahuang was much weaker than that of rhubarb. The reason lies in the difference between the contents of combined anthraquinones component. While acute toxicity in mice of Tudahuang is stronger than that of rhubarb. Thus, Tudahuang should not simply replace rhubarb in practice.
