Specimens of skin, skeletal muscle, adipose tissue, brain, peripheral nerve and catilage were taken from 6 cadavers (divided into 2 groups) perfused and embalmed with formalin. 90 pieces of the above-mentioned tissues were taken in different times and the paraffin sections were stained by routine HE. Electron microscopic observation was made from some skin and skeletal muscle specimens, and histochemical methods were used to demonstrate DNA, RNA, keratin(-SH, -SS), fatty acids and calcium in some skin materials. Loyez stain method for myelin sheath was applied to some brain and nerve sections.1. Skin tissue: In both group A and B, 83.3% and 78.9% of skin materials were appraised as grade I and II (excellent and good) respectively. The morphological changes appeared mainly as karyopyknosis of the epidermal cells and shrinkage of the secretory part of the sweat glands. Most of the skin tissues of the corpses perfused 3～4 hrs after death were well preserved, only 8.3% being in grade Ⅲ (moderate). On the other hand, 43% of skin materials taken from those perfused 30 hrs after death were in grade Ⅲ. Ultrastructurally, the shape of the epidermal cells and their adhensions still remained intact, but karyopyknosis or chromolysis and autolysis of most of the cytoplasmic membraneous structures were found. In those cadavers preserved for less than one year, there was no evidence of progressive changes in microscopic and submicroscopic structures of the skin. The tonofillaments and desmosomes were still kept well in those specimens preserved for many years, and their presence may be the cause of maintaining cell integrity. Histochemically, mercapto-reaction of keratin was kept stable and found to be well shown even in old samples of skin, but the disulfide reaction usually showed marked fading with time, probably due to exofolition of the stratum corneum. However, this reaction was well shown in the hairs and not weakened for many years.2. Fat tissue: Hydrolysis of lipid substances of subcutancous fat and sebaceous gland, as shown by the presence of fatty acid, was found in the corpses preserved even as short as half a year.3. Skeletal muscle: The preservation state of the skeletal muscle was also dependent on the complete perfusion in time. The structure of the muscle fibers was generally worse preserved than that of the skin as shown in severe myolysis. Since stagnation of the small blood vessels frequently accompanied myolysis, obstruction of microcirculation which prevented the permeation of fomalin into the muscle tissues may be the cause of rapid myolysis. The ultrastructural changes of the muscle fibers were the same as those of the epidermal cells. In all specimens even as old as 30 years, two types of myofillaments were well preserved, and bands could be seen distinctly.4. Nervous tissue: The brain tissues were well preserved in those corpses that were perfused shortly after death, but the peripheral nerves usually showed severe autolysis, obviously it is due to the same reasons as those for myolysis.5. Cartilage: The structural changes of cartilage after death were slow and all specimens of cartilage were well preserved.

ObjectiveTo study the neuron protection mechanism of Uncariae Ramulus Cum Uncis extract for the MPTP-induced PD mice.MethodsC57BL/6 mice were randomly divided into control group, model group, Uncariae Ramulus Cum Uncis extract group and madopar group, and injected with MPTP in abdominal cavity. Behavior test was used to detect grabbing capacity and body movement coordination capacity: three biochemical indexes (SOD, MDA, GSH-Px) were detected by biochemical process and the activity of two immune enzyme-linked indexes (IL-1β, IL-6) were detected by enzymelinked immunosorbent assay.ResultsCompared with the control group, the autonomic activity numbers of mice increased and climbing pole time decreased in the model group (P<0.05), enzymatic activity of SOD and GSH-Px decreased significantly and the contents of MDA, IL-1β and IL-6 increased obviously (P<0.01). Compared with model group, the autonomic activity numbers of mice increased and climbing pole time decreased in the Uncariae Ramulus Cum Uncis extract group and madopar group (P<0.05). Enzymatic activity of SOD and GSH-Px increased and the contents of MDA and IL-1β and IL-6 decreased (P<0.05,P<0.01).ConclusionUncariae Ramulus Cum Uncis extract can reduce neuronic apoptosis PD mice, whose therapeutic action may be realized through eliminating oxygen free radicals, improving oxidation resistance and reducing inflammatory reactions.

Objective To optimize the prescription ofBaichanting Tablets by the central composite design-response surface methodology.Methods The doses of MCC, cCMC-Na, SiO2, and magnesium stearate were set as investigation factors; disintegration time and moisture rate were set as indexes. Linear equation quadratic polynomial described mathematic relationship of disintegration time and moisture rate with other four influence factors. Response surface was described according to the optimal mathematic models; the optimal prescription was chosen; predictive analysis was conducted.ResultsThe relationship of disintegration time and moisture rate with other four influence factors could not be described by linear equation. When quadratic polynomial matching was used, correlation coefficients were 0.837 9 and 0.923 1, with relatively high reliability. Optimal prescription contained 30.6%MCC, 10%cCMC-Na, 0.30%SiO2, and 0.10% magnesium stearate. The theoretical value and predicted value deviations of the disintegration time limit and moisture absorption rate were within 5%.Conclusion The predictability of the established model is good. Application of central composite design-response surface methodology can precisely optimize the prescription ofBaichanting Tablets.

Objective To assess the diagnostic value of transient elastography (TE) for the staging of liver fibrosis and cirrhosis in patients with chronic hepatitis C.Methods Systematic and comprehensive literatures related to diagnosis value of TE for chronic hepatitis C were searched in FMJS biomedical database (from Jan.1st,2003 to Aug.31st,2013).Full texts were obtained from PubMed,EBSCO,Elsevier Science,Ovid,Wiley database.The quality of the studies was rated with quality assessment of diagnostic accuracy studies (QUADAS).The accuracy of TE in diagnosing liver fibrosis and cirrhosis were assessed by Stata software bivariate mixed effects model.Results Twenty seven eligible studies which included 5 937 subjects were enrolled.The meta-analysis of fitting the bivariate mixed effects model showed that the pooled sensitivity,specificity,positive likelihood ratio,negative likelihood ratio,diagnostic odds ratio,and the area under curve (AUC) of summary receiver operating characteristic (SROC) for liver fibrosis were 0.75(95％CI:0.70-0.80),0.84(95％CI:0.78-0.88),4.70(95％CI:3.60-6.20),0.29(95％CI:0.24-0.36),16.00(95％CI:12.00-22.00) and 0.86(95％CI:0.83-0.89),respectively.And those for cirrhosis were 0.86(95％CI:0.82-0.89),0.89(95％CI:0.86-0.92),8.10(95％CI:6.30-10.40),0.16(95％CI:0.12-0.20),51.00(95％CI:35.00-76.00) and 0.94(95％CI:0.91-0.96),respectively.Conclusions TE shows better diagnostic accuracy for cirrhosis than for significant fibrosis in patients with chronic hepatitis C.More high quality trials are required to further confirm this finding.

Objective To evaluate the biological toxicity of heavy metals by using Caenorhabditis elegans. Methods The C. elegans at L4 stage were exposed to CdCl2 CrCl3 As2O3 PbCl2 HgCl2 with low concentrations and M9 buffer the control group for 72 h respectively and the effects of heavy metals with different concentrations on the survival time and reproduction of C. elegans were evaluated. Results After exposure to 2.5 10μmol/L HgCl2 and PbCl2 10μmol/L CdCl2 and 50μmol/L CrCl3 for 72 h respectively the life spans and survival curves of the C. elegans were different from those in the control group the differences were statistically significant all P<0.05 . After exposure to CdCl2 CrCl3 As2O3 PbCl2 and HgCl2 with the con?centrations of 2.5 50 100μmol/L for 72 h respectively the generational time and brood size of C. elegans were all different from those in the control group all P<0.01 . Among the 5 heavy metals at low concentrations the reproduction toxicity of Hg was bigger than Pb Cd Cr and the toxicity of As was the weakest. Conclusion Heavy metal exposure can affect the life span and reproductive toxicity of C. elegans.

Objective To investigate the prevalence of hypothyroidism during the second trimester and its relationship with thyroid peroxidase antibody (TPOAb). Methods Two thousand one hundred and forty one pregnant women whose gestational age between 14 to 28 weeks,accepted their prenatal care at the outpatient clinic of International Peace Maternity & Child Health Hospital from March 1,2010 to July 31,2010 were enrolled into this study. Serum TPOAb,thyroidstimulating hormone (TSH) and free thyroxine (FT4) of these women were detected. Logistic regression model was used to analyze the risk factors of subclinical hypothyroidism and positive TPOAb,while Spearman rank correlation was used to analyze the relationship between the levels of TSH,FT4 and TPOAb. Results (1) Subclinical hypothyroidism was detected in 13.36％ (286/2141) patients. Isolated maternal hypothyroxinemia occurs in 0.14％ (3/2141) of pregnant women.No overt hypothyroidism patient was detected and 6.26％ (134/2141) of all pregnant women exhibited positive TPOAb(≥50 U/ml).(2) Positive rate of TPOAb in subclinical hypothyroidism group,isolated maternal hypothyroxinemia group and normal thyroid function group was 13.64％ (39/286),0/3 and 5.06％ (86/1701) respectively,and there was difference among the three groups (x2 =30.82,P＜0.01).The positive rate of TPOAb did not relate to fetal gender,maternal age,gestational age,gravidity and parity.(3) TPOAb had positive relationship with TSH level (r=0.12,P＜0.01),while did not relate to FT4 level (r=-0.04,P=0.09). (4) Positive TPOAb (OR 3.18,95％ CI:2.10-4.83,P＜0.01) and gravidity (OR=1.21,95％ CI:1.02-1.43,P=0.030)were risk factors of subclinical hypothyroidism. Conclusions Hypothyroidism is common during the second trimester. It is necessary to screen TPOAb in pregnant women as TPOAb is an independent and important predictor of subclinical hypothyroidism.
