Garcinia plants are one of the rich sources of natural xanthones and benzophenones which have attracted a great deal of attention from the scientists in the fields of chemistry and pharmacology. Recently, many structurally unique constituents with various bioactivities, especially anti-tumor activity, have been isolated from Garcinia plants. This concise review focused on the anti-cancer activity natural products isolated from Chinese Garcinia plants, and the research finding by authors and collaborators over the past several years were cited.

Objective To study the clinical result of the surgical treatment of upper cervical vertebra disease from high anterior cervical retropharyngeal approach.Methods Among 14 patients,there were 7 C_(2.3)disc hernia- rions combined with C_(2.3)dislocations,3 Hangman fractures,2 odontoid process fractures and 2 C_3 tumors.All patients underwent the high anterior cervical retropharyngeal approach.10 cases were given discectomy of C_(2.3)or focus clear- ance of C_3,iliac bone autograft or titanium cage filled and internal fixation with titanium plate.2 cases of odontoid process fractures were given anterior screw fixation.Results 14 cases got successful exposure.The decompression, reduction,lesion clearance and fusion with internal fixation were done in all patients.There were no important vascu- lar or nerve injuries.The surgical treatment could improve the spinal cord nerve function to a certain degree for the cases with compression of spinal cord.Conclusion Good exposure of upper cervical spine and effective surgical oper- ation could be achieved from high anterior cervical retropharyngeal approach,with minimal trauma and complication, and it was a favorable approach.

Objective To explore the protective effect of L-carnitine on neonates with myocardial injury caused by as?phyxia. Methods Forty-four neonates with myocardial injury caused by asphyxia were randomly divided into L-carnitine treatment group (21 cases) and control group (23 cases). Patients in control group were received routine treatment and pa?tients in treatment group were given L-carnitine 0. 1 g/(kg · d) on the basis of routine treatment for 7 days. Symptoms and physical signs were observed before therapy and during the treatment in two groups. Before and after the treatment, plasma levels of free L-carnitine and cardiac troponin I (cTnI) were detected with the method of colorimetric assay and chemilumi?nescent, respectively. Results The clinical effective rate was significantly higher in treatment group than that of control group (90.48%vs 60.87%, P<0. 05). Compared with the control group, there was a significantly higher plasma concentra?tion of free L-carnitine in treatment group after treatment [(27.00±5.69)μmol/L vs (13.20±3.04)μmol/L, P<0.05]. In treat?ment group, plasma concentration of free L-carnitine was significantly higher after treatment than that of pre-therapy [(14.87 ± 3.95)μmol/L,P<0.05]. Compared with the control group, there was a significantly lower plasma concentration of cTnI after treatment in treatment group [(0.025±0.006)μg/L vs (0.046±0.010)μg/L, P<0.05]. In the treatment group, there was a significant correlation between decreased plasma concentration of cTnI and increased plasma concentration of free L-carnitine (r=0.899, P<0.05). Conclusion Administration of L-carnitine can effectively decrease the abnormal plasma lev?el of cTnI in neonates with myocardial injury caused by asphyxia, and thereby protect the myocardium.

·AIM:To present a case of late onset bilateral keratectasis after laser in situ keratomileusis (LASIK) for myopia with rigid gas-permeable contact lenses with a brief review of literature on this subject.·METHODS:A 27-year-old woman underwent bilateral uneventful LASIK for moderate myopia. Preoperative cycloplegic refractions were -5.50/-0.50×50° right eye (OD) and - 4.50/-1.00×15° left eye (OS).Corneal pachymetry was 526μm OD and 541μm OS, Preoperative corneal topography was normal and did not reveal any keratoconus or forme fruste keratoconus.Following the creation of flaps with 160μm plates,ablations of 102μm OD and 86μm OS were performed,estimated to leave residual stromal beds of 264μm OD and 295μm OS.·RESULTS:Twenty-nine months postoperatively,the patient developed bilateral inferior keratectasia of -12.50/-4.00×160° OD and -6.00/- 4.25×125° OS.Visual acuity was reduced in both eyes;the central cornea had steepened; and pachymetry showed central corneal thinning.Keratectasia was diagnosed,and rigid contact lenses were fitted.Three years later,the patient achieved satisfactory visual acuity and all-day lens wear with minimal complications.·CONCLUSION:Late keratectasia may follow LASIK for low to moderate myopia despite a thorough preoperative work-up.Rigid contact lenses can offer a safe,reversible option for improving visual acuity in such patients by delaying or avoiding the need for intracorneal ring segments implanting or penetrating keratoplasty.
