Methods Noumenon dissect and B-type ultrasonic apparatus was used to observe condition of gallbladder calculus formation in HCD group and normal control group; gallbladder motility function of the two groups were measured; radioimmunoassay was used to measure plasma CCK level in fast and 30min after fatty meal; colorimetry was used to measure cholesterol concentration in bile; and the pathologic changes of gallbladder specimen were observed. Results The gallbladder cholesterol calculus formation rate and cholesterol concentration in bile of HCD group was remarkably higher than that in normal control group (P

Clinical epidemiological studies have shown that vitamin D deficiency is associated with infectious diseases, which is confirmed by recent studies implying the role of vitamin D as a key regulator of host defense against infections. Bioactive vitamin D triggers antimicrobial pathways against pathogens in mucous membrane and cells of the human innate immune system. In addition, vitamin D also attenuates excessive inflammation and acquired immunity, and thus limits collateral tissue damage. The observed effects of vitamin D on infectious diseases, particularly airway infections, should be addressed in the management of viral infections. Findings from cross-sectional studies should be confirmed by prospective research. In this review, we summarize the current knowledge regarding the effect of vitamin D on innate and acquired host defense against infections.

Objective To evaluate the clinical efficacy of laparoscopic radical prostatectomy.Methods A total of 11 cases of laparoscopic radical prostatectomy were enrolled in this study.Among the cases,transperitoneal approach was used in 4 patients,and extraperitoneal approach was employed in 7.The prostate,seminal vesicles,and ampulla ductus deferens were resected,and then the bladder was anastomosed with the urethra.Results The operation was successfully performed in all the patients with a mean operation time of 304 min(180-390 min),and a mean blood loss of 520 ml(300-1200 ml).The postoperative catheterization time and hospital stay were 12-28 d(mean,19.8 d)and 12-24 d(mean,20 d)respectively.No injuries to the rectum,urinary incontinence,or urethral stenosis occurred in this series.The patients were followed up for 1-36 mon(mean 11 mon),during this period,no local recurrence or distant metastasis were found.The postoperative PSA level was 0-0.05 ?g/L.Conclusion Laparoscopic radical prostatectomy is safe and effective for the treatment of prostate cancer.

[Objective]To evaluate the effect of treating the osteochondral defects with implanted cell-scaffold composites,cultured MSCs as seed cells and PLGA as scaffolds,and to acquire desirable seed cells and scaffold materials.[Method]BMSCs were induced to differenciatiated into chondrocytes,co-cultured with PLGA scaffold respectively in vitro,then implanted into osteochondral defects on canine models by using techniques of mosaicplasty,induced BMSC-PLGA scaffold composites in the top of the defect and BMSC-PLGA scaffold composites in the bottom of the defect,osteochondral composites were constructed in vivo,and repair was observed with naked eyes and histology.[Result]At 16 weeks after transplantation the defects of expeirmental group were covered with semi-transparent smooth white tissue and the margins between the repair tissue and the surrounding cartilage were not recognized.Histologically,most of the repair tissue was consisted with chondrocytes,maintained their thickness to the full depth of the original defects.The subchondral bone was well remodeled.The tidemark was observed.The defects of positive control group were covered with repair tissues,and partial were conformed with original cartilage.The repair tissue was partly filled with chondrocytes.However,the defects of negative control group were repaired with soft fibrous tissues without luster,and an obvious boundary between reparative and original cartilage was seen.[Conclusion]MSCs-PLGA scaffold composites,constructed into osteochondral composites by suppressing closely in vivo,are the ideal materials for repairing cartilage defects.

OBJECTIVETo evaluate the effect of repeated sintering on the color and translucency of dental lithium disilicate-based glass ceramic.

METHODSThirty disc specimens (10 mm in diameter, and 1.00 mm ± 0.01 mm in thickness) were fabricated using an IPS e.max Press HT A2 ingot and then randomly divided into six groups (SO, S1, S2, S3, S4, and S5) (n = 5). Each group was sintered 0, 1, 2, 3, 4, and 5 times individually according to the manufacturer's recommendation. After polishing, ultrasonic cleaning, and drying, the color parameters (L*, a*, and b* values) and transmittance (τ) of all the specimens were measured using a ShadeEye NCC dental colorimeter and a TM-2 spectrophotometer, respectively. Subsequently, C*ab and ΔE were calculated. The results were statistically analyzed using SPSS 17.0 software for ANOVA and LSD.

RESULTSAfter repeated sintering, the L* value significantly decreased (P < 0.05), and the a*, b*, and C*ab values initially increased and then decreased (P < 0.05). The color parameters (L*, a*, and b*) and the C*ab values of group S3 were higher than those of the other groups. The τ values initially increased and then decreased (P < 0.05), and these values were optimal when sintered twice. In terms of transmittance (τ), statistical differences existed between the following groups: S0 and S2, S0 and S3,.S2 and S5, and S3 and S5 (P < 0.05). Compared with group S0, the color differences ΔE were 0.89 minimally and 2.01 maximally after different sintering times, which can be clinically acceptable.

CONCLUSIONRepeated sintering can affect the color and translucency of the IPS e.max Press lithium disilicate-based glass ceramic, but the color difference can be clinically acceptable.

Objective: To discuss the rational drug application of Kawasaki disease in children with upper respiratory tract infection in order to provide reference for the therapy of Kawasaki disease suspected of bacterial meningitis.Methods: The medical record of a 2-year-old boy with Kawasaki disease was retrospectively analyzed, and the anti-infection treatment was analyzed and evaluated.Meanwhile, the mechanism of elevated leukocyte count in cerebrospinal fluid (CSF)of children with incomplete Kawasaki disease was discussed.The pharmaceutical care and treatment results in the diagnosis and treatment process were analyzed as well.Results: The anti-infective therapy in early stage was reasonable as the early symptoms of respiratory tract infection in the child were obvious, however, the choice of aztreonam was defective.On the premise of the clinical diagnosis of Kawasaki disease and excluding bacterial meningitis, the medication was timely adjusted.Finally, the symptoms of the child were improved.Conclusion: The application of anti-infection drugs should be reasonable in clinics, and the abnormality in cerebrospinal fluid should be paid more attention in children with Kawasaki disease.It is necessary to strengthen clinical observation and pharmaceutical care in order to guarantee the safety of medication for patients.

Objective To analyze the outcomes and prognostic factors associated with the death of systemic lupus erythematosus (SLE) patients admitted to the intensive care unit (ICU). Methods During June 1996 to June 2007, all SLE patients admitted to the ICU were included. Patients were excluded if the diagnosis of SLE was established at or after ICU admission. A multivariate logistic regression model was applied using variables that were associated with death in the univariate analysis. Results A total of 101 patients meeting the criteria were included. The mortality rate was 48.6%. The most common causes of admission was lung disorder with acute respiratory distress syndrome (ARDS). Multivariate logistic regression analysis suggested that SLICC/ACR DI>7.7 (OR=6.87), APACHE Ⅲ≥21 (OR=29.8), lung disorders with ARDS (OR =55.81 ), septic shock (OR =32.22 ), intracranial haemorrhage (OR =57.35 ), hypocytopenia (OR = 5.89), mean equivalent prednisone dose>25 mg/d (OR=7.65) and prolonged tracheal intubation (OR=5.98) were signi-ficantly associated with death. Whereas sex, age, SLEDAI >27, gastrointestinal bleeding, the cumulative dosage of CTX higher than 1.0 g, pulse intravenous methylprednisolone therapy were not associated with death. Conclusion The mortality rate of critically ill SLE patients in ICU is very high. SLICC/ACR DI> 7.7, APACHE Ⅲ≥21, lung disorders with ARDS, septic shock, intracraniai haemorrhage, average prednisone equivalent dosage higher than 25mg/d and prolonged tracheal intubation (longer than 4 days) are negative prognostic factors in SLE patients admitted to the ICU.

Objective To investigate the change of serum alpha-L-fucosidase(AFU)and its correlation with the blood glucose and lipid level in small for gestational age(SGA)fetuses. Methods 125 SGA fetuses and 128 fetuses in appropriate for gestational age(AGA)with wet lung were treated in our hospital and were investigated as case control study. The serum of AFU ,blood glucose and lipid were measured and compared within 24 hours after birth in these 2 groups. Results Comparing with the AGA infants ,the SGA babies had lower level of serum AFU,high density lipoprotein,apolipoprotein A and apolipoprotein B(P<0.05). The correlation analysis showed that the serum AFU level has positive correlation with blood glucose,total cholesterol,high density lipoprotein, low density lipoproteinand apolipoprotein A(P < 0.05),while it has negative correlation with serum triglycerides in SGA(P<0.05). Conclusions The SGA infants have lower level of serum AFU and lipid metabolic disorders after birth,and its serum AFU level has correlation with its blood glucose and lipid level.
