The incidence of malignant melanoma, a highly fatal skin tumor, is on the rise worldwide. Melanomas are highly aggressive and have strong metastatic capability that leads to lethality. Recurrence occurs in patients with distant metastases, even with the latest treatments, and median survival is only a few months. At present, the prevention and treatment of melanoma includes surgical resection, chemotherapy, immunotherapy and targeted therapy. However, these strategies can lead to drug resistance and adverse effects. In recent years, an increasing number of studies have found that natural products have effective anti-melanoma activities, including inhibition of tumor growth, induction of cell apoptosis, inhibition of angiogenesis and metastasis and toxicity to tumor stem cells. In addition, several studies have reported that the combination of natural products and traditional anti-melanoma drugs can enhance the therapeutic efficacy. In this review we summarize the prevention and treatment of melanoma with natural products.

Objective: The chemical constituents in the methanol extract from the flowers of Trollius ledebouri were rapidly identified using UPLC-Q-TOF-MS in positive and negative ion modes. Methods: The analysis was performed on an ACQUITY UPLC BEH C18 reverse phase column (100 mm × 2.1 mm, 1.7 μm). The mobile phase consisted of methanol and 0.1% formic acid was used for gradient elution, 0-5 min, 95%-60% A; 5-13 min, 60%-45% A; 13-20 min, 45%-0% A; 20.1-25 min, 95% A. The flow rate was 0.3 mL/min, the injection volume was 2 μL. The information of the compounds was analyzed by the positive and negative ion mass spectra and elements composition. Results: The results indicated that 14 compounds in the extract from the flowers of T. ledebouri had been identified by direct comparison in both positive and negative ion mass data, they were vevatric acid, vanillic acid, orietin, orietin-2″-O-β-L-galactopyranoside, orietin-2″-O-β-D-xylopyranoside, quercetin, hyperoside, vitexin, apigenin, luteolin, acacetin-7- O-neohesperidoside, acacetin, pectolinarigenin, and salvigenin. Conclusion: UPLC-Q-TOF-MS could be used to analyze the constituents in the extract from flowers of T. ledebouri and to provide the protection for the quality control of the pieces as well as the stability and efficacy in the late stage clinical application, and to provide a reference for clarifying the material basis of its efficacy.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

Objective To investigate the effect of intraocular injection of mixed crystalline in vivo on survival of retinal ganglion cells(RGCs)after optic nerve cut.Methods Twenty Long-Evens rats were divided into normal control,and 7 day,14 day,and 21 day groups after optic nerve was cut off.There were 5 eyes in each group.Mixed crystallin(1x10~(-4)g/L)and isotonic saline solution were injected into the vitreous of fight eye and left eye respectively.The number of RGCs was counted 7,14 and 21 days after optic nerve cut.Results The density of RGCs declined clearly 7 days after optic nerve cut.In the group with crystallin injection,the density of RGCs declined to 71%,32% and 15% of the control group repec- tively,much higher than that of the controls on days 7,14 and 21 after optic nerve was cut off(P

OBJECTIVETo study the protective effect of formula of removing both phlegm and blood stasis (TYTZ) on myocardial tissues of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Danlou tablet group, and TYTZ groups with doses of 2.0, 1.0, 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome in Chinese mini-swine. After the operation, they were administered with drugs for 8 weeks. The SOD activity and MDA content of each group were observed at the 0th week (before the experiment), the 2nd week after the high-fat diet (before the operation or drug administration) , the 6th week after the high-fat diet (4 weeks after the drug administration) and the 10th week after the high-fat diet (8 weeks after the drug administration). Meanwhile, the myocardial enzymogram test and the HE staining pathological observation were performed at the end of the experiment. The changes in the myocardial cell ultra-structure were observed under transmission electron microscope.

RESULTCompared with the normal control group, the model group showed significant decrease in serum SOD activity and notable increase in MDA content from the 2nd week to the end of experiment (P < 0.05 and P < 0.01). In the 10th week, the CK, LDH and CK-MB levels in serum also significantly increased in the model group (P < 0.05 and P < 0.01), with obvious structural abnormality in myocardial tissue pathologic morphology and ultra-structure. Compared with the model group, TYTZ groups showed specific increase in serum SOD activity and oblivious decrease in the MDA level (P < 0.05 or P < 0.01). Meanwhile, TYTZ could significantly decrease serum CK and LDH levels in the model group (P < 0.05 or P < 0.01), attenuate the ischemia injury of myocardial tissue, and improve the ultra-structure of cardiomyocytes.

CONCLUSIONTYTZ shows an obvious protective effect on the myocardial injury in Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome. Its mechanism is related to the resistance against free radical oxidation injury and the inhibition of the lipid per-oxidation.

OBJECTIVETo sum up the clinical experience in the management of benign prostatic hyperplasia (BPH) with the prostate weighing over 80 ml by transurethral resection of the prostate (TURP) combined with 2 μm continuous-wave laser vaporesection (LVR).

METHODSWe retrospectively analyzed the clinical effects of TURP combined with 2 μm LVR in the treatment of 46 cases of BPH with the prostate volume > 80 ml.

RESULTSAll the operations were successfully accomplished. The operation time and intraoperative blood loss were (112.0 ± 20.0) min (range 86-176 min) and (77.9 ± 25.9) ml (range 50-200 ml), respectively. The catheters were withdrawn at 7 days after surgery. Transient urinary incontinence occurred in 6 cases and secondary hemorrhage was found in 2 postoperatively. Six-month follow-up revealed no urethral stricture or other complications. Compared with the baseline, the international prostate symptom score (IPSS) was significantly decreased at 6 months after operation (26.3 ± 1.8 vs 11.6 ± 1.7, P <0.05), and so were the quality of life (QOL) score (5.3 ± 0.7 vs 1.3 ± 1.1, P <0.05) and post-void residual urine (PVR) ([115.5 ± 55.6] ml vs [19.9 ± 11.6] ml, P <0.05). However, the maximum urinary flow rate (Qmax) was remarkably increased from (4.1 ± 2.6) ml/s to (16.2 ± 1.7) ml/s (P <0.05).

CONCLUSIONTURP combined with 2 μm LVR is safe and effective for the treatment of BPH with the prostate volume >80 ml.

OBJECTIVETo investigate the expression of c-myb in reflux esophagitis, Barrett esophagus and esophageal adenocarcinoma.

METHODSThe expression levels of c-myb in the esophageal mucosa tissue of patients with reflux esophagitis, Barrett esophagus and esophageal adenocarcinoma were detected by real-time fluorescent quantitative RT-PCR.

RESULTSThe expression levels of c-myb mRNA in Barrett esophagus and esophageal adenocarcinoma tissues was significantly higher than that in normal and reflux esophagitis esophageal tissue (P<0.05 or 0.01), and increased progressively with the development of reflux esophagitis into Barrett esophagus and esophageal adenocarcinoma.

CONCLUSIONSThe expression level of c-myb mRNA is closely related with the development of Barrett esophagus and esophageal adenocarcinoma, and may be used as a valuable index for monitoring the early onset and intervention of Barrett esophagus and esophageal adenocarcinoma.

OBJECTIVETo study the combination of Mandibular distraction and orthognathic techniques for the reconstruction of adult hemifacial microsomia.

METHODSThe three-dimensional CT reconstruction data was used with Mimics for preoperation design. The osteotomy location, distraction vector, distraction distance were decided before operation with a surgical guider. At the first stage, internal distractor was implanted after ostetomy through an extra-oral approach. The distraction begun 5-7 days after operation with a frequency of 1 mm/day. After distraction, the distractor was maintained for 3-6 months. At the second stage, the distractor was removed. Le Fort I osteotomy was performed in order to correct the cross-bite and improve the facial contour. Usually, bone graft was inserted into the gap after Le Fort I osteotomy. The genioplasty was also performed if necessary.

RESULTS9 cases of adult hemifacial microsomia with severe mandibular deviation were treated. The facial asymmetry were improved greatly. 1 patient suffered an wound infection in the maxillary region after Le Fort I osteotomy and healed uneventfully with wound irrigation.

CONCLUSIONSMandibular distraction combined with orthognathic surgery is an effective procedure for adult hemifacial microsomia with complicated mandibular hypoplasia.
