1.Bone cancer pain induce anxiety-like behavior and high expression of NR2B subunit in anterior cingulate cortex of rats
The Journal of Clinical Anesthesiology 2016;32(5):495-499
Objective To investigate the effect of bone cancer pain on emotion and NMDA re-ceptor NR2B subunit expression level in anterior cingulate cortex (ACC)in rats.Methods One hun-dred and fifty healthy male Wistar rats weighing 200-250 g aged 3 months old were randomly divided into 3 groups (n = 50 in each group):sham operation group (group S),bone cancer pain group (group BCP),RO25-6981 group (group RO).The BCP model was established by inoculating Walker 256 breast cancer cells into right intra-tibial.Rats in group S were given the same dose of d-hanks. Group RO was injected intraperitoneally with RO25-6981 (5 mg/kg/d)on the day of inoculation, while rats in the group S and group BCP were given the same dose of normal saline.Mechanical with-drawal threshold (MWT)and thermal withdrawal latency (TWL)of right hind legs were measured on day 7,10,14 after inoculation respectively.Elevated plus-maze test was carried out to investigate the effect of bone cancer pain on emotion in rats after pain threshold detection,then the percentage of the times entering the open arms (OE)and the percentage of the time staying in the open arms (OT) duration the total period were evaluated.Then the anterior cingulate cortex tissue was removed to e-valuate the NR2B protein and mRNA expression levels by RT-PCR,Western blot and immunofluo-rescence methods on day 14 after elevated plus-maze test.Results All the parameters did not differ with significant difference between group S and group RO.MWT decreased and TWL shortened on day 7,10,14 after inoculation in group BCP compared with those before inoculation and those of group S and group RO.OE and OT in group BCP reduced remarkably than those before inoculation and those of group S and group RO.Relative absorbance of NR2B mRNA,the expression of NR2B pro-tein,average NR2B relative fluorescence intensity value is obviously higher than that of group S and group RO (P <0.05).Conclusion Bone cancer pain can induce pain-related aversion and anxiety-like behavior of rats,and the mechanism may be related to the high expression of NR2B in anterior cingu-late cortex.
2.Effect of tetrandrine on murine hemangioendothelioma cell and its molecular mechanisms
Chinese Journal of Biochemical Pharmaceutics 2015;(3):54-57
Objective To explore tetrandrine on murine hemangioendothelioma cell and its mechanisms.Methods Explore the effect of tetrandrine on EOMA cells in time and concentration MTT experiment, the content of tetrandrine treated EOMA cells in different cell cycle detected by flow cytometry, speculated effect of tetrandrine on G1/S phase checkpoint for EOMA cells blocking.Western blot analyzed the molecular mechanism of tetrandrine induced EOMA cell block, and intracellular reactive oxygen species level were detected byflow cytometry.Then used the active oxygen scavenger NAC pretreated cells after drug incubation.Results Tetrandrine could inhibit the cell reproduction, and showed a concentration and time dependence, role in tetrandrine 20μM was significantly inhibited after 48 h.Tetrandrine caused mainly by EOMA cells during the cell cycle of G1/S phase cell block, so as to achieve the effect of inhibiting cell proliferation.Tetrandrine increased intracellular reactive oxygen species ( ROS) blockade effect of elevated levels of cell cycle to achieve, and the regulation of AKT, GSK-3 βand p53 cell cycle upstream protein level, finally maked the expression changes.Further research proved that, tetrandrine induced up-regulation of ROS level in cells to induce EOMA cell cycle arrest.Moreover, regulated by the ROS inhibitor NAC could significantly inhibit EOMA cell cycle factor.Conclusion Tetrandrine can inhibit tumor angiogenesis, which provides theory basis for clinical anti-cancer drugs in inhibiting tumor growth.
3.Effects of 8-bromo-7-methoxychrysin and sorafenib on apoptosis of liver cancer stem-like cells
Chinese Journal of Tissue Engineering Research 2015;(45):7263-7267
BACKGROUND:We tried to combine 8-bromo-7-methoxychrysin and sorafenib in order to offset the tolerance of hepatocelular cancer stem cels to sorafenib, thereby comprehensively improving the therapeutic efficacy on hepatocelular carcinoma. OBJECTIVE:To observe the effects of 8-bromo-7-methoxychrysin, sorafenib and their combination on apoptosis of liver cancer stem-like cels SMMC-7721, and to analyze their mechanisms. METHODS:SMMC-7721 cels were treated with 8-bromo-7-methoxychrysin, sorafenib alone and their combination for 24 hours. Then, flow cytometry was used to detect cel apoptosis and western blot assay was used to determine nuclear factor-κB protein expression. RESULTS AND CONCLUSION:Compared with 8-bromo-7-methoxychrysin group and sorafenib group, the apoptotic rates of SMMC-7721 cels were significantly enhanced after treatment with the combination of 8-bromo-7-methoxychrysin group and sorafenib (2.5, 5, 10, 50 μmol/L), and meanwhile, the protein expression of nuclear factor-κB was down-regulated significantly. These findings indicate that the combined therapy of 8-bromo-7-methoxychrysin group and sorafenib can enhance the apoptosis of SMMC-7721 cels, which may be associated with down-regulation of nuclear factor-κB protein.

Journal of Regional Anatomy and Operative Surgery 2016;(1):33-34
Objective To discuss the biological and pathological features, diagnosis, treatment and prognosis of primary malignant mel-anoma of the foreskin. Methods The diagnosis, treatment, and follow-up of one case of primary malignant melanoma of foreskin treated in our hospital was reported, and the related literatures were reviewed. Results The tumour stage of the patient was stage I, and the patient was given partial amputation of the penis and bilateral inguinal lymph node dissection. Chemotherapy and immunotherapy were conducted at the same time. And there was no recurrence metastasis of during the postoperative follow-up of 54 months. Conclusion Primary malignant melanoma of the foreskin is rare in clinical and it is of high malignant degree. Its diagnosis depends on pathology and surgery is the main treatment. Postoperative chemotherapy and immunotherapy can prolong the survival time of patients, but the overall prognosis is poor.

9.Clinical Observation on Comprehensive Treatment on Cutaneous Region for Low Back Pain
Journal of Acupuncture and Tuina Science 2014;(4):246-250
Objective: To observe the clinical effects of comprehensive treatmenton cutaneous region for low back pain.
Methods: One hundred and twenty outpatients with low back pain who met the diagnostic criteria were randomly divided into a cutaneous region group or a medication group, 60 cases in each group. The cases in the cutaneous region group were treated by Nie-pinching up the skin of the lumbosacral region, cupping and acupuncture. Those in the medication group were treated by oral administration of Celecoxib capsule. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to assess the therapeutic effects.
Results: After treatment, the VAS scores of both groups were different from those before treatment, showing statistical significances (allP<0.01). The D-valuse of VAS scores of both groups were different from those before treatment, showing statistical significances (allP<0.01). The D-value of OID scores in the cutaneous region group was significantly different from that in the medication group(P<0.01). After treatment, the total effective rate was 91.7% in the cutaneous region group versus 76.7% in the medication group, there was a significant difference in comparing the clinical effect (P<0.01).
Conclusion: Both comprehensive treatment on the cutaneous region and Celecoxib capsule can obviously relieve low back pain. But comprehensive treatment on the cutaneous region is better than Celecoxib capsule in the therapeutic effects.
