To assess the effect of prostaglandin E_1(PGE_1)on renal blood flow and serum endothelin of liver recipients.Methods PGE_1 was administered in 38 liver recipients at the dose of 0.6?g?kg~(-1)?h~(-1)during liver transplantation and every day after operation.The effects of PGE_1 on serum endothelin concentration and creatinine(Cr)were observed and these indexes were compared with those in the control group(n=18).The renal blood flow resistance indexes(RI)were measured by Doppler ultrasound.Results Cr and RI were significantly lower in PGE1=treated group than those in the control group.PGE_1-treated group also showed a significantly lower serum endothelin concen- tration.Conclusion Administration of PGE_1 in liver recipients can significantly improve the early re- nal function by reducing serum endothelin concentration and dilating renal blood vessels.

Microwaves can be directly transformed into heat inside materials because of their ability of penetrating into any substance. The degree that materials are heated depends on their dielectric properties. Materials with high dielectric loss are more easily to reach a resonant state by microwaves field, then microwaves can be absorbed efficiently. Microwave irradiation technique with the unique heating mechanisms could induce drug-polymer interaction and change the properties of dissolution. Many benefits such as improving product quality, increasing energy efficiency and reducing times can be obtained by microwaves. This paper summarized characteristics of the microwave irradiation technique, new preparation techniques and formulation process in pharmaceutical industry by microwave irradiation technology. The microwave technology provides a new clue for heating and drying in the field of pharmaceutics.

Objective To evaluate the value of diffusion-weighted imaging(DWI)on differential diagnosis of intracranial cystic lesions.Methods Seventy-six patients with surgically and pathologically confirmed intracranial cystic lesions undergone conventional MRI,DWI and contrast enhanced MRI examination.The signal characteristics of intracrania]cystic lesions on DWI were analysed retrospectively, the apparent diffusion coefficient(ADC)values of cystic areas were measured quantitatively.Results Nineteen brain abscesses showed hyperintense signal on DWI.Among 34 brain tumors,3 brain gliomas were hyperintense signal,1 brain glioma was isointense signal and 1 metastasis was hyperintense signal;the other 29 brain tumors showed hypointense signal on DWI.The ADC values of all lesions were:(0.62?0.15)? 10~(-3)mm~2/s in brain abscesses,(2.39?0.78)?10~(-3)mm~2/s in brain gliomas,(2.68?0.40)? 10~(-3)mm~2/s in brain hemangioblastomas,(2.79?0.79)?10~(-3)mm~2/s in brain metastases,respectively. There were significant differences between the ADC values of brain abscess and the cystic or necrotic portions of brain glioma,hemangioblastoma,metastasis(P0.05). Seven intracranial arachnoid cysts showed hypointense signal and 16 epidermoid cysts strikingly hyperintense signal on DWI.The ADC values of arachnoid cysts and epidermoid cysts were(2.96?0.36)?10~(-3)mm~2/s and(0.94?0.13)?10~(-3)mm~2/s respectively.There was significant difference between the ADC values of arachnoid cysts and epidermoid cysts(P

OBJECTIVETo systematically evaluate the efficacy and safety of kidney-tonifying traditional Chinese medicine in the treatment of male infertility.

METHODSBased on the principles and methods of Cochrane systematic reviews, we searched CNKI, VIP, and Wanfang databases from inception to December 2012 for randomized controlled clinical trials addressing the treatment of male infertility with kidney-tonifying traditional Chinese medicine. According to the inclusion and exclusion criteria and retrieval strategies, we extracted the data, evaluated the quality of the included literature, and conducted meta-analysis using the RevMan 5. 2 software.

RESULTSTwenty trials involving 2,272 patients were included, and the sample size of each study was from 60 to 270 cases. All the studies were graded as of poor quality, with Jadad scores of no more than 3 points. The results of meta-analysis showed that the total effectiveness rate of traditional Chinese medicine versus Western medicine on male infertility was RR = 1.71, 95% CI 1.19-2.47, and that of Chinese-Western combined therapy versus Western medicine was RR = 1.15, 95% CI 1.01-1.30. Both traditional Chinese medicine and Chinese-Western combined therapy showed a significantly better total effectiveness than Western medicine alone in improving the pregnancy rate without serious adverse reactions.

CONCLUSIONDue to the poor methodological quality and high heterogeneity of the included studies, the evidence for the efficacy and safety of kidney-tonifying traditional Chinese drugs in the treatment of male infertility is of but limited value, and further validation is needed by more high-quality studies.

Objective To investigate the prevention of glucocorticoid-induced osteoporosis or bone loss in systemic lupus erythematosus (SLE) patients by Bugu capsules.Methods Sixty-six patients with SLE were randomly divided into A and B groups:34 patients in Group A were treated by glucocorticoid and Bugu capsules,and 32 patients in Group B by glucocorticoid alone.All patients were measured for bone mineral density (BMD) in Wards triangle,and for related biochemical parameters such as serum calcium, phosphonium,alkaline phosphatase,parathyroid hormone (PTH) and interleukin-6 (IL-6) before and after the treatment.As the control group,thirty healthy subjects were measured for the above parameters.Results There was significant difference in the serum level of IL-6,calcium and PTH between the Group B and con- trol group (P＜0.01).The occurrence rate of osteoporosis or bone loss in group A was significant lower than that in group B [2/34 (5.88%) vs 9/32 (28.13%),P=0.0364].Conclusion Bugu capsules can prevent glucocorticoid-induced osteoporosis or bone loss in SLE patients,possibly by restoring the balance among serum IL-6,calcium and PTH.

Objective To observe the abnormal Minnesota code (MC) distribution and interrelated characteristic on electrocardiograms (ECGs) of the adult Kazakh population.Methods Resting ECGs and blood press of randomly sampled 30 000 adult Kazakh people in three Northern regions of Xinjiang were continuously examined and analyzed,using Minnesota code recommended by WHO as the classification of ECG.Results The overall rate of abnormal ECG findings was 248.60‰,and the main abnormality in males was 146.83‰,compared to 157.71‰ in females.The prevalence rates of abnormal ST-T changes,the total arrhythmia and atrial fibrillation (AF) were 100.03‰,71.17‰ and 2.83‰ respectively.There were statistically significant differences among the main abnormities from the three regions.Conclusion The ECGs abnormalities of adult Kazakh people were high.There was significant relation found between the main abnormalities and hypertension.The prevalence of AF was different from the domestically reported literature that calls for further study.

OBJECTIVETo study the possible immunological mechanism of wheezing attack in children with cytomegalovirus (CMV) infection.

METHODSA total of 25 under-5-year-old children with wheezing following CMV infection were enrolled. The expression of serum regulatory T cells (Treg)/T helper 17 (Th17) cytokines interleukin (IL)-10, IL-6, and IL-17, and peripheral blood lymphocyte subsets were determined. Twenty age-matched healthy children were selected as the control group.

RESULTSThe wheezing group had a significantly reduced serum IL-10 level, significantly increased IL-6 and IL-17 levels, significantly reduced levels of natural killer cells, and significantly increased levels of CD8+ T cells and CD19+ B cells, as compared with the control group.

CONCLUSIONSWheezing children with CMV infection have Treg/Th17 imbalance and cellular immune dysfunction, which may be an important immunological mechanism of the development of wheezing in children after CMV infection.

OBJECTIVETo investigate the relationship between the changes of the copy numbers of mtDNA in peripheral blood mono-nucle- ar cell(PBMC) and the disordered of antioxidant capacity of hepatocellular carcinoma (HCC) patients.

METHODSThe Ficoll Hypaque method was used to isolate the PBMC from blood specimens. The ND1 gene of the mitochondrial was amplified by real-time PCR; meantime β-actin was served as a quantitative standard marker; the difference of mtDNA copy number in PBMC was compared between HCC and healthy control group. The level of reactive oxygen species (ROS) in PBMC was determined by flow cytometry. The change of total antioxidant capacity (T- AOC) of plasma was detected by the biochemistry examination.

RESULTSThe copy numbers of ND1 gene in PBMC of HCC was 73% that of the healthy control group,which suggested a decrease of the copy numbers of mtDNA in HCC. The levels of ROS of PBMC in HCC was (417. 82 ± 110.62) and (301.82 ± 75.54) in control group, which showed that the levels of ROS of PBMC in HCC were significant higher than that in control group (P < 0.01).Plasma T-AOC in HCC was (1.30 ± 0.85), and (3.20 ± 1.62) in control. The T-AOC of plasma of HCC was significantly lower than in control group (P < 0.01).

CONCLUSIONThere was a certain relationship between the decrease of the copy numbers of mtDNA and the disordered antioxidant capacity in hepatocellular carcinoma, which may be associated with the development of hepatocellular carcinoma.

OBJECTIVETo evaluate the marginal microleakage of porcelain-fused-to-metal crown using four different cements.

METHODSSixteen porcelain-fused-to-metal crowns were built and randomly divided into 4 group, luted onto standard prepared human forward molars using four different cements (glass ionomer cement, resin-modified glass ionomer cement, PanaviaF, Super-Bond C&B adhesive luting system). After temperature cycling test, all the crowns were then submerged in 2% fuchsin for 24 h. The marginal microleakage at tooth cement interfaces was observed using light stereomicroscopy and evaluated in classification index. The marginal microleakage grade of 4 groups were analyzed by SPSS 13.0.

RESULTSThe PanaviaF demonstrated the least marginal microleakage, Super-Bond C&B adhesive luting system, resin-modified glass ionomer cement showed an intermediate level of marginal microleakage, glass ionomer cement was associated with severe marginal microleakage (total, Chi2 = 157.60, P < 0.01; among the different groups, P<0.05).

CONCLUSIONAdhesive resin luting system which is the first selection in clinical is better than glass ionomer cement and is good at porcelain-fused-to-metal crown.

OBJECTIVE: To study the effect of basic fibroblast growth factor(b-FGF) on revascularization and bone remodeling of allogeneic mandible transplantation in repair of mandible defects in rabbits. METHODS: The mandible defects of 20 adult rabbits were created in both sides. The defects on the left side were implanted with allogeneic bone and local administration of b-FGF; the defects on the right side were only repaired with allogeneic bone as control group. At 1, 3 months after operation, the revascularization and bone remodeling were observed by ink-gelation vascular perfusion-transparency and histological examination. RESULTS: The allogeneic bone and b-FGF group had more marked vascularization and more quick and complete bone formation than control group. CONCLUSION: b-FGF can improve revascularization and bone formation after allogeneic mandible transplantation; allogeneic bone combined with b-FGF is a promising bone substitute in clinical uses.
