Objective To investigate the effect of dexamethasone with subdose ketamine on restraining the pulling-dragging reflex during appendectomy. Methods 114 ASA grade Ⅰ～Ⅱpatients of appendectomy undergoing T 11 ～L 1 epidural anesthesia were randomly divided three groups,each group containing 38 cases. Group Ⅰ recieved the dexamethasone 10mg and ketamine 0 5mg/kg by venous injection before opening abdominal cavity, groupⅡ received pethidine 50mg and droperidol 2 5mg before begining operation, and group Ⅲ without any drugs served as control. The pulling-dragging reflex of appendix, the sedative state at pulling-dragging appendix and the change of pulse oxygen saturation (SpO 2) or mean arterial pressure (MAP) were recorded and analyzed. Results The excellent rates of groupsⅠ, Ⅱ and Ⅲ were 100%, 81 58% and 18 42% respectively,and there was significant difference between group I and the other groups (P

Objective: Pemetrexed (PEM) is a multi-targeted chemotherapeutic agent for antifolate drugs. PEM has become the standard agent for the second-line treatment of advanced non-small cell lung cancer (NSCLC). This study aims to review and analyze the clinical efficacy and adverse reactions of PEM combined with carboplatin with respect to NSCLC treatment. Methods: A total of 40 patients suffering from NSCLC were selected and confirmed by pathology. On the first day of treatment, the conventional 500 mg/m2 dose of pemetrexed disodium was infused intravenously. On the second day, a combined therapy with carboplatin was conducted based on the conventional dose for a 21-day cycle with at least two cycles for each patient. The therapeutic efficacy and adverse reactions were evaluated and were compared with the proposed regimen of gemcitabine (GEM) combined with carboplatin. Results: After two cycles of the treatment, the curative effects of the PEM and GEM groups were 50% and 45%, respectively. The main adverse reactions are bone marrow suppression and gastrointestinal reactions. The incidence rates of bone marrow suppression, gastrointestinal reactions, amisulpride/AST, urea nitrogen, rash, and hair loss were obviously lower in the PEM group than in the GEM group. Statistically significant differences in adverse reaction were found between the two groups (P<0.05). Conclusion: The use of the combination regimen of PEM with carboplatin showed significantly more clinical effects and less adverse reactions for NSCLC treatment.

Objective To study the quality standard of Gegenbao Soft Capsule.Methods The qualitative identification of puerarin and daidzein was carried out by TLC,and the contents of puerarin and daidzein were determined by HPLC.Results Puerarin and daidzein could be identified by TLC with high specificity.The linearity was from 0.214 to 1.42 ? g for puerarin and from 0.033 to 0.221 ? g for daidzein by HPLC,and the average recovery was 101.5 % for puerarin and 96.6 % for daidzein with RSD 1.6 % and 1.8 % respectively(n=6).Conclusion This method is simple,accurate and reliable for the quality control of Gegenbao Soft Capsule.

Vitamin D receptor (VDR) genotypes and bone mineral density (BMD) of 611 subjects in Shanghai were investigated. The results indicated that the frequency of Bb genotype in male is higher than that in female (26.9% vs 12.7%, P

To investigate the repairing effect of fibrochondrocyte collagen construct in meniscus lesion, fibrochondrocytes were isolated and expanded in vitro , then seeded onto collagen construct .18 dogs with wedged shape lesion in the lateral meniscus were randomly divided into 3 groups: the lesion were filled with either cell collagen construct or collagen or untreated. The lateral meniscus was then examined grossly and histologically at different periods. The results showed that the lesions that had been filled with fibrochondrocyte collagen construct healed with fibrocartilage tissue. The results suggest that tissue engineering method is practical.

To investigate the behavior of meniscal fibrocartilage cells in vitro ,human meniscal fibrocartilage cells were harvested from adolescents and sequentially digestied with 0 50% trypsin and 0 2% collagenase (type2). The isolated cells were cultured in Ham'sF 12 medium and identified by histochemical methods. Cell proliferation, morphology and ultrastructure were observed by phase contrast microscope and electronic microscope. In primarily cultured cells, fusiform cells dominated and they were confirmed by the positive result of immunohistochemical examination for type collagen staining. Our results indicate that it is a simple and highly effective method.

Background A preliminary study determined an application of manganese ion eyedrops in tracing observation of visual system in vivo,but whether manganese ion has toxic effects on ocular anterior segment tissues is still unclear.Objective This study was to investigate the toxic effects of different concentrations of manganese ion eyedrops on ocular anterior segment tissues.Methods Thirty-two clean New-Zealand white rabbits were divided into 1.00 mol/L MnCl2 group,0.50 mol/L MnCl2 group,0.25 mol/L MnCl2 group and normal control group according to random number table.The experimental eye was randomly chosen from each rabbit for eyedrops application.The manganese ion eyedrops at concentration of 1.00 mol/L,0.50 mol/L or 0.25 mol/L was topically administered in any lateral eye of each rabbit in the 1.00 mol/L MnCl2 group,0.50 mol/L MnCl2 group,0.25 mol/L MnCl2 group,and normal saline solution was used in the same way in the normal control group.In 2 hours,1 day and 3,7,14,21,28 days after eyedrops application,the irritative response of ocular surface was examined under the slit lamp microscope,and corneal damage was evaluated by corneal fluorescence staining,and corneal endothelial cell density (ECD) and corneal thickness were assessed using corneal specular microscope.The eyeball samples were prepared in 3,7,14 and 28 days after eyedrops application and hematoxylin and eosin staining was performed for histopathological examination of conjunctiva,cornea,trabecular meshwork and ciliary body tissue.The use and care of experimental animals complied with the Statement of ARVO.Results Severe hyperemia and edema in palpebral conjunctiva appeared in the 1.00 mol/L MnCl2 group and 0.50 mol/L MnCl2 group,and the symptoms reached a maximum level 1 day after eyedrop application and disappeared 7 days after eyedrops application in the 1.00 mol/L MnCl2 group.These symptoms were milder in the 0.50 mol/L MnCl2 group in comparison with the 1.00 mol/L MnCl2 group.There were no ocular irritative response in the 0.25 mol/L MnCl2 group.Significant differences were found in the corneal fluorescence scores among the groups 2 hours,1 day,3 and 7 days after eyedrop application (X2 =17.350,19.200,12.200,10.140,all at P＜0.05),with the highest score in the 1.00 mol/L MnCl2 group.The ECD was not significantly different among the groups and different time points (Fgroup =0.38,P＞0.05;Ftime =1.79,P＞0.05).The corneal thickness value was significantly different among the groups and different time points (Fgroup =18.22,P＜0.05;Ftime =116.75,P ＜ 0.05).The corneal thickness value was elevated during 2 hours to 3 days after administration of eyedrops in the 1.00 mol/L MnCl2 group and closed to normal from 7 days to 28 days.The corneal thickness value was higher from 2 hours to 14 days than that in 28 days after administration of eyedrops in the 1.00 moL/L MnCl2 group,and the corneal thickness value was higher in 2 hours to 1 day than that in 28 days after administration of eyedrops in the 0.50 mol/L MnCl2 group (all at P＜0.05).Inflammatory cell infiltration and stromal edema were exhibited in conjunctival,trabecular meshwork and ciliary body tissue in the 1.00 mol/L MnCl2 group 3 days and 7 days after eyedrops application,and only inflammatory cell infiltration in conjunctival tissue in the 0.50 mol/L MnCl2 group 3 days after eyedrops application.No obvious abnormity was seen in the 0.25 mol/L MnCl2 group.Conclusions 1.00 mol/L manganese ion eyedrops has a remarkable toxic effect on ocular anterior segment tissue in rabbit.With the lowing of drug concentrations,the toxic effects were reduced.The manganese-enhanced MRI using 0.25 mol/L manganese ion eyedrops is feasibility bacause of its non-toxicity to ocular tissues.
