AIM: To assess the changes of macular thickness of acquire immunodeficiency syndrome ( AIDS) patients.
METHODS:The study based on the data analysis of 38 human immunodeficiency virus ( HIV ) positive patients ( 64 eyes ) . According to CD4 count and whether cytomegalovirus retinitis ( CMVR) happened, the patients were divided into 3 groups. Group A included 16 patients (32 eyes), in which CD4 count was < 50cells/μL and CMVR did not happen. Group B included 10 patients ( 20 eyes), in which CD4 count was>50cells/μL and CMVR did not happen. Group C included 12 patients (12 eyes), in which CD4 count was < 50cells/μL and CMVR just happened. Group D included 10 healthy people ( 20 eyes ) , as normal control group. By using optical coherence tomography ( OCT ) , thickness of retina along with a 1mm diameter circle centered on macular was evaluated.
RESULTS:The mean foveal thicknesses in groups A, B, C and D were 254. 03±15. 63μm, 263. 11±17. 12μm, 304. 50±50. 62μm and 257. 64±8. 54μm in order. Compared with foveal thickness in each group, there were significant differences in general (F=12. 933, P=0. 000). The mean foveal thickness in groups CMVR increased, which was of significant difference (P= 0. 000), compared with other groups.
CONCLUSION: CMVR can impair the structure and function of macular, which then seriously affects the visual function of patients. It's helpful to understand the progress and prognosis of CMVR disease by observing macular structure with OCT in early time.

OBJECTIVETo provide a new material for producing the Rhodiolasachalinensis products, the effect of methyl jasmonate (MeJA) on callus biomass and effective compound accumulation of Rhodiolasachalinensis was studied.

METHODThe calluses-cultured in 3 L-air lift balloon type bioreactor were treated with MeJA after 20 d of bioreactor culture and the effect of MeJA concentration and treatment days on callus biomass, salidroside or polysaccharide accumulation and superoxide dismutase (SOD) and peroxidase (POD) activities were investigated.

RESULTThe callus biomass was not significantly different after MeJA treatment (125) for 0-6 d but obviously decreased after 6 d treatment. The maximum salidroside or polysaccharide contents and SOD or POD activities were found after 4 d treatment of MeJA. MeJA concentration significantly affected callus biomass and effective compound accumulation, biomass decreased at MeJA concentrations higher than 125 μmol x L(-1). However, the effective compound contents were determined at higher MeJA concentration, and the highest salidroside and polysaccharide accumulation was found at 225 and 275 μmol x L(-1) MeJA, respectively and the maximum SOD and POD activities was found at 225 μmol x L(-1) MeJA. The effective compound contents in callus were compared with field-grown plants. Salidroside contents in calluses were 1.1-fold and 2. 4-fold more than in plant roots and stem or leave, respectively. Polysaccharide content in calluses were 3. 6-fold and 8.0-fold more than in plant roots and stem or leave, respectively.

CONCLUSIONSalidorside and polysaccharide in Rhodiolasachalinensiscalluses improved by MeJA treatment, 225 μmol x L(-1) MeJA and 4 d treatment were optimal. The effective compound contents in callus were obviously higher than in field-grown plants. Therefore, bioreactor culture is efficient for obtaining mass effective compounds of Rhodiolasachalinensis by culturing calluses. This method could provide an alternative material source for production of Rhodiolasachalinensis products.

To improve cell suspension culture system of Panax ginseng, the dynamic of cell growth and medium consumption were studied, and the effects of filter on the culture vessel, revolution number, and inoculation density on cell growth and ginsenoside accumulation were also investigated. The maximum cell growth and ginsenoside accumulation was found on the 20th days of suspension culture, therefore, 20 days were confirmed as a suitable culture period for mass production of ginsenoside. Cell growth and ginsenoside content were promoted when the culture vessel had a ventilated filter. Revolution speed during suspension culture affected cell growth, but not ginsenoside content, a peak of ginsenoside productivity was found in the treatment of 120 r x min(-1). Inoculation density also influenced cell growth and ginsenoside accumulation, inoculation density of 6 g was better than other inoculation densities, the ginsenoside content and productivity were up to 12.8 mg x g(-1) DW and 146.6 mg x L(-1), respectively.

Objective To provide a practicable method for the complete display and localization of the posterolateral structures (PLS) of the normal knee through MRI study. Methods 30 tibial bone specimens were observed to establish the bony landmark for localizing the knee. In 50 cadaver knees, the angles between lateral tibial plateau and the long axis of the individual structure of PLS were measured. Then the scan methods of the oblique MR images were determined based on above results. The routine and oblique scans of T 1WI were performed in 40 normal knees. The display effect and appearance of the PLS were observed on MRI. Results The lateral tibial plateau was a stable bony landmark for measuring and localizing of the knee. In the 40 normal knees, The fibular collateral ligament could be intactly displayed on 70? posterior coronal oblique images in 34 cases (85%). The popliteus could be better seen on either 45? medial sagittal oblique in 34 cases (85%) or 60? posterior coronal oblique planes in 36 cases (90%). The popliteofibular ligament could be intactly appreciated on both 60? posterior coronal oblique in 32 cases (80%) and 70? lateral sagittal oblique images in 34 cases (85%). Although the arcuate ligament and the fabellofibular ligament could occasionally be seen on routine and oblique images, but the display rate was lower. Conclusion The oblique MR imaging can intactly display the main structures of PLS, and can be useful in diagnosing the injuries in those structures.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Background Congenital fibrosis of extraocular muscles (CFEOM) affects patient' s appearance and quality of life,and no effective treatment for this disease is available.Imaging study is helpful for exploring the pathogenesis of CFEOM.Objective This study was to describe the characteristics of CFEOM associated with limb movement disorder using magnetic resonance imaging (MRI).Methods A family with CFEOM associated with limb movement disorder was investigated in Renmin Hospital of Wuhan University.Disease history was collected and the pedigree was investigated.Ophthalmologic examinations,including corrected visual acuity,refractive error,slitlamp examination,ophthalmoscopic examination,force of levator palpebrae superioris,ocular movement,eye position,forced duction test,and bell phenomenon examination,were performed.Ocular orbital and cranial MRI was performed in 4 CFEOM patients and 10 normal subjects to compare the structures of the extraocular muscles,motor nerve and cranium.Oral informed consent was obtained from each patient prior to any medical examination.Results A total of 1 1 members from 3 generations were investigated in this study,presenting with 4 cases of disease.The mode of inheritance of this family complied with the Mendelian autosomal dominant inheritance law.Clinical signs included disturbance of eye movement,deviation of eye position,ptosis,lack of Bell sign and positive reaction of passive pull test.In addition,unstable gait,improper body limb alignment,dysphasia and mental retardation were ohserved in 1 patient,which coincided with the diagnostic criteria of type 3 CFEOM.MRI results demonstrated that the levator palpebrae superioris,superior rectus and superior oblique muscle were clearly thinner,and the medial rectus,lateral rectus,inferior rectus muscle were thinning in the patients,showing significant differences in comparison with the normal controls(P＜O.05).The oculomotor and abducens nerves became thinner and even absent in the patients.Cranial MRI showed that Ⅲ-3 in the pedigree with callosum was shorter than that of the normal controls,suggesting that patient suffered from corpus callosum hypoplasia.Meanwhile,cranial MRI indicated the presence of cerebellar hypoplasia and the expansion of the fourth ventricle.Conclusions MRI demonstrates consistent abnormalities of the oculomotor nerves and abducens nerves in the affected individuals in this CFEOM 3 family,and some affected members exhibit two types of central nervous system abnormalities-corpus callosum and cerebellar hypoplasia.These findings suggest that CFEOM 3 is primarily a neuronal disease.
