Journal of Shanghai Jiaotong University(Medical Science) 2006;0(10):-
Objective To compare the effects of total intravenous anesthesia(TITA) by using remifentanil combined with propofol and intravenous-inhaled anesthesia by using propofol combined with sevoflurane on emergence agitation(EA) in children undergoing surgery of obstruction sleep apnea syndrome(OSAS). Methods Forty children of 3 to 7 years old scheduled for elective surgery of OSAS were randomly divided into TITA group(group T,n=20) and combined anesthesia group(group C,n=20).Patients in group T were induced with remifentanil 1 ?g/kg,midazolam 0.2 mg/kg,propofol 2.5 mg/kg and rocurolnium 0.6 mg/kg and maintained with remifentanil(0.4-0.5 ?g?kg-1?min-1) and propofol(4-6 mg?kg-1?h-1) until the end of the operation.Patients in group C were induced with midazolam 0.2 mg/kg,propofol 2.5 mg/kg and rocurolnium 0.6 mg/kg and maintained with propofol 4-6 mg?kg-1?h-1 and sevoflurane inhalation(1.2-1.4 MAC) until the end of the operation.EA was evaluated by 5-point scoring scale.

Injectable bone substitutes can repair bone defect via percutaneous injection, including organic bone graft materials and inorganic bone graft materials. Furthermore, some materials considered as vector can composite with cells to generate tissue engineering materials, which are injected into bone graft to improve fusion rate. The development of injectable bone substitutes provides a new way to treat some relative diseases. Here, the article was divided three parts to introduce biological characteristics and clinical application of organic bone substitute materials, inorganic bone substitute materials, and bone tissue engineering vector materials. Although bone tissue engineering research achieves some effects initially, there are still a lot of problems, such as collection and preparation of extracellular matrix materials, composite and transplantation of cell and vector; all of them need to be further studied.

In natural condition, two years were needed for Panax quinquefolius seeds to break dormancy. In the first year, the embryo developed slowly, and the activities of amylase and peroxidase were low. In the second year the embryo developed rapidly, and the activities of both enzymes also increased gradually. But with the treatment of hormones enzymatic activ ities accelarated remarkably and speeded up the decomposition of stored nutrients in endos perm, so that starch and non-reducing sugar decreased while reducing sugar incrcased rapidly, resulting in earlier germination.
8.Determination of Entrapment Efficiency of Loratadine Binary Ethosomes by Sephadex Microcolumn Com-bined with HPLC
China Pharmacist 2015;(2):244-246
Objective:To establish a method to determine the entrapment efficiency of loratadine binary ethosomes. Methods:The gel microcolumn centrifugation method was employed to separate the free drug from loratadine binary ethosomes. The content of lorata-dine was determined by HPLC to calculate the entrapment efficiency. Results: A calibration linear curve of loratadine concentration was within the range of 10. 2-102. 0 μg·ml-1(r=0. 999 5). The average entrapment efficiencies of three batches of loratadine binary ethosomes were 86. 75%, 87. 26% and 86. 00%, respectively. Conclusion:The method is simple and rapid, and can be used to de-termine the entrapment efficiency of loratadine binary ethosomes accurately.

Abstract: Objective To explore the relationship between peripheral blood and pleural effusion tuberculosis (TB)
infection effector T cells, and to further evaluate the value of combined pleural effusion adenosine deaminase (ADA) for rapid
diagnosis of tuberculous pleurisy. Methods The test data of 80 cases of tuberculous pleurisy and 70 cases of nontuberculous
pleurisy treated in the Sixth People's Hospital of Nantong City from January 2017 to December 2020 were analyzed. The TBinfected effector T cells were also detected simultaneously in the peripheral blood and the pleural effusion by the T-SPOT
technique, and the pleural effusion ADA was detected by the rate method. The subject operating characteristic curve (ROC) was
applied to take the optimal pleural effusion ADA threshold to compare the sensitivity and specificity of different critical values.
Person phase analysis was applied to analyze the correlation between peripheral blood and pleural effusion T-SPOT.TB. Data of
peripheral blood, pleural effusion T-SPOT.TB and ADA were integrated. Results When pleural effusion ADA>45 U/L, the
sensitivity and specificity for the diagnosis of tuberculous pleurisy were 50.0% and 94.3%, respectively; when ADA > 25.15 U/
L, the sensitivity and specificity were 80.0% and 72.9%. When ADA > 45 U / L, pleural/ blood T-SPOT.TB spot ratio (spot
forming cells, SFCs) > 2 times, the specificity for the diagnosis of tuberculous pleurisy was 100% (highest); when 25.15 U/L<
pleural effusion ADA ≤ 45 U/L, pleural/blood T-SPOT.TB spot ratio > 2 times, the specificity for the diagnosis of tuberculous
pleurisy was 92.3% (second). When pleural effusion ADA ≤ 25.15 U/L, and the pleural effusion/blood T-SPOT.TB spot number
ratio > 2 times, with 83.3% specificity (the lowest of the three groups). Conclusions The level of pleural effusion ADA is one
of the most used methods for diagnosing tuberculous pleurisy. Further combination of pleural effusion and blood T-SPOT.TB, if
the ratio of pleural effusion / blood T-SPOT. TB spots is greater than 2 times, it can further improve the diagnosis rate of
tuberculous pleurisy.

Objective To observe the expression level of HOXB6 gene on the differentiation and proliferation of hematopoietic stem cells(HSC) to colony forming unit-granulocyte-monocyte(CFU-GM),erythroid progenitor(CFU-E) and colony forming unite-T-lymphocyt(CFU-TL).And the proliferation procress was affected by all-transretinoic acid(ATRA).Methods 1.By the colony culture in vitro,the impact of ATRA on the CFU-GM,CFU-E,CFU-TL colony formation were surveyed;the expressions of HOXB6 gene were observed on the differentiation procress of HSC to CFU-GM,CFU-E and CFU-TL affected by ATRA on the 3rd,7th,12th.2.Real-time fluorogenic quantitative reserve transcription-polymerize chain reaction(FQ-RT-PCR) method was used to explore the possible mechanism of ATRA up-regulated to human cord blood CFU-GM,CFU-E and CFU-TL in gentic level.Results 1.HOXB6 gene had a regulatory function in the differentiation procress of hematopoiesis.During the differentiation and proliferation of HSC to colony forming CFU-GM or CFU-E,CFU-TL in vitro,the expressions of HOXB6 gene were significant positive.2.Compared with the expressions of CFU-GM and CFU-TL HOXB6 mRNA on day 3,the quantity of HOXB6 mRNA was obviously higher on day 7 and lower on day 12,respectively in each group.Compared with the expression of CFU-E HOXB6 mRNA on day 3,the quantity of HOXB6 mRNA was obviously higher on day 12 in each group.3.Compared with the HOXB6 gene of control group,the expressions of HOXB6 gene of group ATRA were up-regulated remarkable.Conclusions 1.HOXB6 gene has a regulatory function in the differentiation procress of hematopoiesis.HOXB6 gene plays an important role in the progress which can be associated with the regulating effect of HOXB6 gene on the differentiation and proliferation of CFU-GM,CFU-E and CFU-TL.2.During the differentiation and proliferation of HSC,the expression of HOXB6 gene is regular in time.3.Low concentration of ATRA(60 ?mol?L-1) can up-regulate the expression of HOXB6 gene,which confirms the theory that the normal hematopoie-tic lineage determination and maturation rely on the stable and consistent expression of HOXB6 gene.
