OBJECTIVETo dynamically assess drug targeting of Yougui Pill (YP) and Zuogui Pill (ZP) using infrared thermography.

METHODSIn this self-control experiment, five healthy volunteers were recruited. By using infrared thermography 10 to 11 thermal images of different body locations were taken from each participant after they took warm water, YP, ZP, and their dissembled prescriptions at 30, 70, 100, 130, and 160 min, respectively. The heat values in the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) were statistically analyzed after scanning for 125 times.

RESULTSAdministration of YP and its disassembled prescriptions enhanced the heat value of the locations of the Du channel and Shenque (CV8), but did no enhance the heat value of the lower quadrant abdomen at 30 min. Administration of ZP and its disassembled prescriptions reduced the heat value in the locations of the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) at each time point.

CONCLUSIONThe drug targeting of ZP and YP focused on the locations of the Du channel and Shenque (CV8), not on the locations of the lower quadrant abdomen or uterus.

Objective To investigate the diagnostic values of model of end-stage with incorporation of serum sodium (MELD-Na) score, chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score and APASL-ACLF research consortium score (AARC-ACLF) for evaluation of prognosis of hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF). Methods A total of 72 consecutive patients with HBV-ACLF were included in the study and divided into two groups (group A and group B) according to the prognosis in three-month. Group A were included 29 patients with stable disease or better after medical treatment at least for 3 months, and group B included 43 patients who were dead after treatment or received liver transplantation as failure of medical treatment. When the patients were diagnosed as ACLF or after admission, the data were collected. Results of the laboratory examination were collected when the international normalized ratio (INR) was minimum. Data of total bilirubin (TBIL), prothrombin time (PT), INR, serum creatinine (Cr), serum sodium (Na), albumin (ALB), MELD-Na, CLIF-SOFA and AARC-ACLF scores were calculated respectively. The comparative analysis was performed. Areas under the receiver operating characteristic curve (AUC-ROC) of MELD-Na and CLIF-SOFA scores were used to assess the short-term prognosis in patients with acute-on-chronic liver failure. Results The values of TBIL, INR, MELD-Na, AARC-ACLF and CLIF-SOFA were significantly higher in group B than those in group A (P<0.05). The serum level of Na was significantly lower in group B than that of group A (P<0.05). The area under curve (AUC) values generated by the ROC curves was higher for CLIF-SOFA score (AUC 0.887) than that of MELD-Na score (AUC 0.764) (Z=2.255, P<0.0167). The AUC values generated by the ROC curves showed no significant differences between CLIF-SOFA score and AARC-ACLF score (AUC 0.825) or MELD-Na score and AARC-ACLF score (Z=1.361, 1.127, P>0.0167). The cut-off scores of MELD-Na, CLIF-SOFA and AARC-ACLF were 23.84, 8.50 and 8.50 respectively. Conclusion MELD-Na, CLIF-SOFA and AARC-ACLF scores have appreciable values to evaluate the prognosis in patients with HBV-related ACLF. AARC-ACLF is better than that of MELD-Na and CLIF-SOFA in assessing prognosis of HBV-related ACLF.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

ObjectiveTo investigate the effect of varied hyperglycemia and durations on preventing peripheral neuropathy (PN) with methylcobal in diabetic rats.Methods80 Sprague Dawley rats were selected and randomly chosen 16 as normal control (NC) group, others 64 animals as diabetic model induced by alloxan. The model rats were evenly divided into relatively good control (GC) group and relatively poor control (PC) group based on levels of hyperglycemia regulated with exogenous insulin. 16 rats of each GC/PC group were intramuscularly injected with methylcobal (500 μg/kg). The sensory nerve conduction velocity (SNCV), motor nerve conduction velocity (MNCV) and evoked potential amplitute (EPA) of sciatic nerve of rats were detected by evoked electromyogram respectively at 2nd, 8th and 12th week after onset of diabetes. Fructosamine in serum was also detected.ResultsThe rats injected with methylcobal had a significantly delayed reduction of SNCV, MNCV and EP in GC group (fructosamine,1.0 mmol/L) than that in PC group (fructosamine, 1.2 mmol/L) ( P<0.05～0.01). Up to 8th week after onset of diabetes, there was no obvious difference in physioelectroparameters between the GC group and NC group. At 12th week after onset of diabetes, physioelectroparameters in the PC group fell to the level of non-methylcobal injected group. No effect of methylcobal on blood glucose revealed in any groups ( P>0.05).ConclusionMethylcobal has a beneficial effect on delaying the onset of diabetic PN, and is of high efficacy with a good control of diabetic state, especially at early stage.
