Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

Objective To investigate the clinical and molecular pathological features of dysferlinopathy in China.Methods Four patients with limb-girdle muscular dystrophy2B(LGMD2B)and 4 patients with Miyoshi-type distal muscular dystrophy(MMD)were clinically analyzed, their skeletal muscle were biopsied and immunohistochemical stained.Four cases of each Duchenne-Aran muscular atrophy and myotis were served as controls.Results The clinical situation of dysferlinopathy was characterized by progressive muscle weakness and atrophy, consistent with progressive muscular dystrophy.Histochemical staining revealed muscle fibers degenerating, regenerating and necrosis in a varying degree.Connective tissue was seen proliferated and inflammatory cells infiltrated in the majority of cases.Immunohistochemical staining with anti-dysferlin monoclonal antibody identified the deficiency of dysferlin on the sarcolemma and in the sarcoplasm of 8 cases with dysferlinopathy.Conclusions(1)The clinical and pathological characters of dysferlinopathy are consistent with progressive muscular dystrophy;(2)Anti-dysferlin monoclonal antibody immunohistochemical staining is a reliable method to diagnose dysferlinopathy, which is worth of wide application in clinic.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

This study examined the ability of 1,2,3,4,6-penta-O-galloyl-β-D-glucose (β-PGG) to induce the expression of heme oxygenase-1 (HO-1) in the PC12 cells and its regulation in the PC12 cells. One week before treatment with the drug, nerve growth factor (NGF) was added to the cultures at a final concentration of 50 ng/mL to induce neuronal differentiation. After drug treatment, HO-1 gene transcription was analyzed by reverse transcription polymerase chain reaction (RT-PCR). Expression of HO-1 and NF-E2-related factor2 (Nrf2) and activation of extracellular signal-regulated kinase (ERK) and Akt were detected by Western blotting. The viability of the PC12 cells treated with different medicines was examined by MTT assay. The oxidative stress in the PC12 cells was evaluated qualitatively and quantitatively by DCFH-DA. The results showed that β-PGG up-regulated HO-1 expression and this increased expression provided neuroprotection against MPP(+)-induced oxidative injury. Moreover, β-PGG induced Nrf2 nuclear translocation, which was found to be upstream of β-PGG-induced HO-1 expression, and the activation of ERK and Akt, a pathway that is involved in β-PGG-induced Nrf2 nuclear translocation, HO-1 expression and neuroprotection. In conclusion, β-PGG up-regulates HO-1 expression by stimulating Nrf2 nuclear translocation in an ERK- and Akt-dependent manner, and HO-1 expression by β-PGG may provide the PC12 cells with an acquired antioxidant defense capacity to survive the oxidative stress.

Objective To evaluate the diagnostic value of CT and PET-CT characteristics in predicting the presence of epidermal growth factor receptor(EGFR) gene mutations in lung adenocarcinomas. Methods One hundred and sixty-eight lung adenocarcinomas cases confirmed by pathology were enrolled in our study. They were divided into EGFR gene mutations group (89 cases) and wild types group (79cases) according to whether EGFR gene mutation occurred. All patients underwent CT examination. Seventy-five patients underwent PET-CT examination, including 37 gene mutationsand 38 wild types.The demographic (the patients' age, the gender and smoking history), CT characteristics(lobulation, cavitation, spiculation, pleural-indentation, air-bronchogram, ground glass opacity/tumor ratio(G/T) and the maximum diameter of tumor(Dmax)) and PET-CT characteristics(the maximum standardized uptake value, (SUVmax))between these two groups were retrospectively compared. The independent sample t test was used to analyze the
difference between these two groups regarding the patients' age,Dmax,SUVmax. The χ2 test was used to demonstrate the difference between these two groups regarding the gender, smoking history and CT features including lobulation, cavitation, spiculation, pleural-indentation, air-bronchogram and G/T.The trend analysis between SUVmax and EGFR gene mutations was performed by usingχ2 test for trend.Results No significant difference was found regarding partial CT characteristics of lesions including lobulation, cavitation, spiculation, pleural-indentation, air-bronchogram (P>0.05),however, the Dmax of EGFR gene mutations group and wild types group were(2.53±1.39),(3.00±1.77)cm, respectively. The amount of G/T>50%in EGFR gene mutations group and wild types group was 21 and 5, respectively. Significant differences were found regarding the G/T and Dmax(χ2=9.538, P<0.05;t=1.974,P<0.05). The SUVmax in EGFR gene mutations group (37 cases) and wild types group (38 cases) were 5.13 ± 4.35 and 9.64 ± 5.12, respectively. Significant difference was found regarding SUVmax(t=4.104, P<0.05). The sensitivity and specificity in predicting EGFR gene mutations were 24%and 93%, respectively, using G/T>50%as diagnostic criterion. Receiver operating characteristic (ROC) results indicated Dmax=1.85 cm was the optimal value in predicting EGFR gene mutations, with the sensitivity and specificity of 76% and 42%, respectively. Meanwhile, SUVmax=6.85 was the optimal value, with the sensitivity and specificity of 71% and 73%, respectively. Moreover,χ2 test for trend showed that an obvious trend was found to associate SUVmax with the incidence of EGFR gene mutations (χ2=15.755, P<0.05). Conclusion SUVmax may be helpful in predicting EGFR gene mutations in lung adenocarcinomas with relatively high diagnostic value.

OBJECTIVE: To evaluate the effect of integrated traditional Chinese and Western medicine therapy on the progression of acute renal failure in patients with chronic renal insufficiency. METHODS: Thirty-two patients with chronic renal insufficiency developed acute renal failure recently were treated with Chinese herbs and western drugs intravenously and clysterizing of Chinese herbs liquid for 30 minutes, and the treatment course was 14 days. Assessment of liver and renal function, blood routine, electrolytes and endogenous creatinine clearance rate (Ccr) was performed before and 2 weeks after the treatment. RESULTS: The levels of hemoglobin (HB), white blood cell count (WBC) and serum electrolytes showed no significant changes after the treatment. The levels of blood urea nitrogen (BUN) and serum creatinine (SCr) decreased, while the level of Ccr increased significantly (P<0.05) after the treatment. The total effective rate was 65.6%. CONCLUSION: The integrated traditional Chinese and Western medicine therapy can effectively delay the deterioration of renal function in patients with chronic renal insufficiency accompanied by acute renal failure.
