Objective:To study the clinico-pathologic characteristics, molecular phenotypes, and prognosis of young breast can-cer patients. Methods:Data from 133 low-age (age≤30 years) young breast cancer patients and 117 young (31 years≤age≤35 years) breast cancer patients who underwent surgery between January 2002 and December 2009 were reviewed. Cases of the middle and old-age elderly (age>35 years) breast cancer patients during the corresponding period were randomly selected as matched controls. The clinico-pathologic characteristics, molecular phenotypes, and prognosis were retrospectively analyzed. Results:The low-age young and young breast cancer patients significantly differed from the elderly patients in terms of tumor size, lymph node metastasis, histological grading, molecular phenotype, and relapse (P<0.05). The low-age young patients are more vulnerable to have triple-negative breast can-cer, recurrence, and distant metastasis (P<0.001). Moreover, the low-age young patients have lower overall survival and disease-free survival than the other groups (P<0.05). Conclusion:Young breast cancer patients have poor prognosis compared with the elderly. Ear-ly screening and prompt treatment are necessary for young breast cancer patients.

Objective To investigate the clinical and pathologic features in patients of microscopic polyangiitis (MPA) with peripheral nerve abnormality.Methods We collected clinical data of 6 patients with MPA that was confirmed by immunological,pathological and clinical findings.Electroneurophysiologic examinations and sural nerve biopsies were performed in these patients.Two normal controls were included in these studies.Results All of 6 patients developed asymmetric polyneuropathies.Electrodiagnostic studies showed reduced amplitudes of the sensory nerve action potential and compound motor action potential with mild impaired conductive velocities.The patients presented vasculitis changes with cell infiltration by monocytes and lymphocytes.Sural nerve biopsies found loss of myelinated fibers in all of the patients indicating axonal degeneration.Some of them associated with regeneration clusters of myelinated fibers.Conclusions Asymmetric neuropathy with sensory nerve injuries is the mainfeature in the MPA associated polyneuropathy.Electrodiagnostic examination indicated axonal lesions in mononeuritis multiplex.Sural nerve biopsies confirmed the active axonal lesions and vasculitis.

Due to the complexity of proteome samples, comprehensive analysis to characterize all proteins was still not possible with present methodologies. It has been shown that replicate runs could increase the number of identified) proteins. However, the redundancy of protein identifications was high. High-abundant peptides tended to be analyzed repeatedly in different runs. To reduce the redundancy and improve the efficiency of identification), we studied the MS/MS acquisition method of linear ion trap Fourier transform ion cyclotron resonance)-mass spectrometry(LTQ-FT) and an acquisition strategy based on exclusion of precursor ions was developed). It proved that the strategy could extremely reduce the redundancy of MS/MS acquisition and improve) the efficiency of protein identifications.

Objective To explore the changes of the plasma motilin(MTL)and serum gastrin(GAS)levels and their relationship with course of disease,the severity,the complication of digestive system in neonates with intracranial haemorrhage(ICH).Methods The objects were 26 cases of term newborns with ICH,the healthy control group contained 30 cases of healthy term newborns.Plasma motilin and serum gastrin concentration were measured by radioimmmunoassay in 26 cases of newborns with ICH in the 2 d,3-5 d,7-10 d,and 12-15 d after birth,and compared with the healthy control group.Results Compared with healthy control group,the blood GAS and MTL levels of neonatal ICH group increased dramatically(Pa

OBJECTIVETo investigate the effect of different pH on rectum permeability of chlorogenic acid and geniposide.
METHODFour kinds of Reduning suppositories of different pH were separated and put into the rectum to study the suppositories in vitro and the content of chlorogenic acid and geniposide samples was determined by HPLC to calculate the permeation in 24 hours.
RESULTWith increase of pH within 2.5-7.4, the steady state flux of chlorogenic acid was increased, but the steady state flux of geniposidesamples was steady.
CONCLUSIONAdjusted the pH can increase the rectum permeability of active ingredients in Reduning auppositories.

The theoretical basis of the alcohol precipitation process control was provided, the alcohol precipitation was optimized and the relationship equation was got. The monod glycoside, loganin and paeoniflorin were used as the evaluation indexes to determine the impact factors of alcohol precipitation techniques of Liuwei Dihuang decoction by the Plackett-Burman experimental design and the levels of non-significant factors were identified. Then, Box-Behnken response surface methodology was used to research and discuss the critical process parameters influence the effect of alcohol precipitation and draw interaction between key process parameters and the correlation equation with index components. Through the establishment and solving the quadratic regression model of composite score, the optimum preparation conditions of alcohol precipitation techniques of liuwei were as follows: stirring speed was 580 r x min(-1), standing time was 17 hours, alcohol concentration was 34%, the density of Liuwei Dihuang decoction was 1.13. The response surface methodology for optimized alcohol precipitation techniques of Liuwei Dihuang decoction is. reasonable and feasible.

Objective: To observe the clinical efficacy of moxibustion therapy plus Liu's pediatric massage (tuina) for children with recurrent respiratory tract infections due to qi deficiency of spleen and lung. Methods: A total of 60 children who met the inclusion criteria were divided into an observation group and a control group according to the visiting sequence, with 30 cases in each group. Children in the observation group were treated with moxibustion therapy plus Liu's pediatric massage, and those in the control group were treated with Liu's pediatric massage alone. The incidence of respiratory tract infections and traditional Chinese medicine (TCM) symptoms score were observed and recorded in both groups before and after treatment. And the clinical efficacy was compared between the two groups. Results: The total effective rate of the observation group was 93.3%, and that of the control group was 83.3%. The difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptoms score and total times of infections in both groups were all statistically different from those before treatment (all P<0.05). The differences in TCM symptoms score and infection frequency before and after treatment in the observation group were statistically different from those in the control group (both P<0.05). Conclusion: Moxibustion therapy plus Liu's pediatric massage has a better effect in improving the clinical symptoms and reducing the frequency of respiratory tract infections for children with recurrent respiratory tract infections due to qi deficiency of spleen and lung than the pediatric massage alone.
