[Summary] There is growing awareness of the importance of vitamin D beyond maintenance of musculoskeletal health.Vitamin D has been shown to have extensive biological functions,including modulating immune function,inhibiting cellular proliferation,inducing differentiation,promoting apoptosis.Vitamin D deficiency is highly prevalent in critically ill patients,and it may impact the severity of illness and contribute to lessthan-optimal outcomes.Vitamin D plays an important role in preventing the development of critical illness based on its pleiotropic actions,thus holding a profound prospective with respect to an adjunctive therapy in critically ill patients.

Objective To evaluate the influence of extraocular counterpulsation on ocular fundus blood vessels using high-frequency color Doppler ultrasonography. Methods Twenty-one patients with ischemic optic neuropathy were treated with extraocular counterpulsation. During treatment, the Doppler spectra were detected with high-frequency color Doppler ultrasonography. The peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance retinal index (RI) of central retinal artery and posterior ciliary artery were measured instantly before treatment and 1 min,5 min and 15 min after treatment. Results The instant PSV and EDV of central retinal artery and posterior ciliary artery were significantly increased (P＜0.05) after treatment, then decreased gradually. Fifteen min after treatment ,they returned to the level before treatment. Conclusions We can observe the changes of ocular fundus blood vessels noninvasively on high-frequency color Doppler ultrasonography. The method may be regarded as one of the basis for evaluating the effect of extraocular counterpulsation.

AIM:To investigate the clinical effects of traditional Chinese medicine, Si Ling San, on acute central serous chorioretinopathy (CSC).METHODS:We retrospectively analyzed the clinical data of 48 patients (48 eyes) with CSC, among whom 24 were given oral Si Ling San (as treatment group) and the other 24 did not receive any treatment (control group).The baseline and 1 or 3mo follow-up data for the best corrected visual acuity (BCVA), central macular thickness (CMT) and maximum height of subretinal fluid (SRF) were collected and then compared between the two groups.RESULTS:BCVA of the treatment group was not statistically different from the baseline level at 1mo (P>0.05), but it was significantly improved at 3mo (P<0.05).BCVA was better at 3mo than that at 1mo(P<0.05).In the control group, however, no significant improvement of BCVA was found at 1 or 3mo compared with baseline (both P>0.05).The BCVA of the two groups was not significantly different at baseline and 1 and 3mo follow-up (all P>0.05).In the treatment group CMT and SRF at 1 and 3mo were significantly lower than baseline (both P<0.05).CMT and SRF at 3mo were significantly lower than that at 1 month (both P<0.05).In the control group, CMT and SRF at 1mo were not different from baseline level (both P>0.05), while they were significantly decreased at 3mo follow-up (both P<0.05).CMT and SRF at 3mo were significantly lower than that at 1mo (both P<0.05).In addition, CMT and SRF of the treatment group at both 1 and 3mo were statistically lower than that of the control group (all P<0.05).CONCLUSION:This study preliminary suggest that oral Si Ling San has the potential to treat acute CSC.But further trials are warranted to study its role in improving the visual function, shortening the duration and reducing the recurrence of CSC.

AIM: To investigate the effect of hirudo and earthworm liquor extract on the expression of syndecan-1 in focal cerebral ischemia reperfusion rats and the relationship between syndecan-1 expression and cellists underlying antiinflammatory mechanism. METHODS: The MCAO models of rats were built with the intraluminal filament occlusion. Rats' brains were cut at the levels of the hippocampus as the templates. Immunohistochemistry staining and HE staining were used to facilitate the observation of the distribution and the quantities of cells with expression of syndecan-1 and the pathological change of MCAO ischemia 2 h reperfusion 4, 24, 72 h and 7 d with hirudo and earthworm liquor extract or saline treatment, respectively. RESULTS: Hirudo and earthworm liquor extract could upregulate the expression of syndecan-1 on ischemia/ reperfusion in rats' brains, especially at 72 h. The numbers of syndecan-1 cells got peak, hirudo and earthworm extract liquor could downregulate polynucleation inflammatory cells at 24 and 72 h. The expression of inflammatory cells in both hirudo and earthworm liquor extract group and saline group at 4 h was not significant. Hirudo and earthworm extract liquor downregulated the monocytic inflammation cells infiltration at 7 d. CONCLUSION: Hirudo and earthworm liquor extract can upregulate the expression of syndecan-1 on ischemia reperfusion in rats' brains. The upregulation of syndecan-1 can decrease inflammatory cell infiltrate.

Objective To explore the expression of syndecan-1 in different intervals following focal cerebral ischemia/reperfusion in rat and the relationship between syndecan-1 and inflammatory cells in the rat brain.Methods The rat model of middle cerebral artery occlusion(MACO) was performed by using the intraluminal filament occlusion for 2 h,then released.The rat brain were cut in the coronal planes at the levels of the hippocampus as the templates.The immunohistochemical staining and HE staining were used to observe the distribution and the quantity of syndecan-1 and inflammatory cell expression in the normal control group,sham operation group and the MCAO groups at 4,24,72 h and 7 d after reperfusion.Results The expression of syndecan-1 was mainly in the cortex and the subcortex in the rats of normal control group and sham operation group.The immunoreactivity of syndecan-1 in the infarcted core and perilesional infarcted zone started decreasing at 4 h after ischemia/reperfusion,reached the lowest at 24 h.The expression of syndecan-1 in the perilesional infarcted zone was up-regulated at 72 h and recovered at 7 d.The relationship between syndecan-1 and inflammatory cells was of negative correlation.Conclusion The decreasing of syndecan-1 may contribute to inflammatory response in the cerebral infarction region after focal cerebral ischemia/reperfusion.

A metabonomics method based on gas chromatography_mass spectrometry ( GC_MS) was developed for detecting the significant differences of root exudates of the Cd hyperaccumulator Sedum alfredii under different treatments and study the effect mechanism of S. alfredii tolerating or accumulating the heavy metal Cd. The root exudates were collected after treatment for 4 and 8 days with 0 and 40μmol/L Cd. The collected solution was lyophilized and dissolved with methanol, and after derivatization with methoxyamine hydrochloride and N_methyl_N_trifluoroacetamide, the samples were analyzed by GC_MS. Principal component analysis ( PCA) and orthogonal partial least_squares discrimination analysis ( OPLS_DA) were carried out for pattern recognition and a clear separation among the different treatments was achieved. Twelve compounds which caused the separation among the different treatments were found and identified. With the change of treatments, the relative amount of these 12 compounds revealed different trends, which indicated that the Cd hyperaccumulator S. alfredii could adjust the secretion of root exudates to tolerate or accumulate the heavy metal Cd.
