Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. This review, we summarized the research findings over the past years, and discussed the nano-reinforcing materials used to prepare molecular imprinting of proteins and the perspective of these nano-reinforcing materials.

OBJECTIVETo explore activity laws of mitochondrial complex II in patients of deficiency-cold syndrome (DCS) and deficiency-heat syndrome (DHS) under various ambient temperatures.

METHODSSubjects were recruited by questionnaire and expert diagnosis from grade 1 - 3 undergraduates at Henan College of Traditional Chinese Medicine in November 2012, and assigned to a normal control group, the DCS group, and the DHS group, 20 in each group. Their venous blood samples were collected at two different temperature conditions. Activities of mitochondrial complex II were measured by spectrophotometry.

RESULTS(1) Comparison of mitochondrial complex It under various ambient temperatures: Compared with room temperature in the same group, activity values were all increased in the normal control group at cold temperature with significant difference (P <0.05), but there was no significant difference in the DCS group and the DHS group (P >0. 05). Compared with the normal control group, activity values of complex H were reduced in the DCS group at cold and room temperatures with significant difference (P <0.05). Compared with the DCS group, activity values of complex It were increased in the DHS group with significant difference (P <0. 05). (2) Changes of adjustment rates: Compared with room temperature, the adjustment rate all rose at cold temperature in the normal control group and the DHS group with significant difference (P <0.05), but with no significant difference found in the DCS group (P >0. 05). Compared with the normal control group at the same temperature, the adjustment rate in the DHS group and the DCS group was all reduced at cold and room temperatures with significant difference (P <0. 05). There were no significant difference in the adjustment rate between the DHS group and the DCS group (P > 0. 05).

CONCLUSIONSEnvironment temperature can affect the activity of mitochondrial complex II with different influence degrees on different syndrome types of people, but its change trend are basically identical.

Objective To evaluate the clinical value of adenosine triphosphate (ATP) determination in CD4+ cells in cytomegalovirus pneumonia after renal transplantation.Methods The ATP level of CD4+ T cells was measured by ImmuKnowTM kit.The ATP levels were determined in 187 renal transplant recipients before and 30,60,90,180 days after operation,and at the time of CMV pneumonia and 4 weeks after treatment of CMV pneumonia.The associations between ATP levels and CMV pneumonia were analyzed.Analysis of variance (ANOVA),Pearson-Spearman and relative risks were used for data analysis.Results 17 cases out of 187 renal transplant recipients were diagnosed as CMV pneumonia (9.1％),and the onset of CMV pneumonia started on the (2.8 ±1.2)month after renal transplantation.ATP concentrations in CD4+ T cells were significantly lower after operation than those before operation (P＜0.01).ATP concentrations reached the lowest on the about postoperative day 90 (P＜0.05),then increased gradually.In 17 recipients with CMV pneumonia,the ATP levels before and 30,90 days after operation,at the time of CMV pneumonia and 4th week after treatment of CMV pneumonia were (376 ±182),(283 ± 146),(196 ± 112),(145 ± 102) and (236 ± 117) μg/L respectively.ATP levels at the time of CMV pneumonia were significantly lower than any other time points (P＜0.05).There was close correlation between ATP levels and CMV pneumonia.Conclusion The determination of ATP in CD4+ cells could reflect the status of cell-mediated immunity in renal transplant recipients,and could evaluate the severity and prognosis of CMV pneumonia and guide the clinical treatment.

Objective To summarize the incidence and treatment experience of the effectiveness and adverse reactions of the different immunosuppressive protocols and to increase the long-term survival rate in kidney recipients. Methods Single-center retrospective analysis was performed on 3102 cases of kidney transplant recipients in effectiveness and adverse reactions of different immunosuppressive protocols. The immunosuppressive protocols were as follows: CsA + Aza + Pred,low dose CsA + MMF + Pred, low dose Tac + MMF + Pred, low dose CsA + SRL + Pred, and low dose Tac+ SRL+ Pred. Results The 1-, 5-, 10-year survival rate of patients/kidney in low dose CsA + MMF + Pred protocol was higher than that in CsA + Aza + Pred protocol. The incidence of adverse reactions, such as hypertension, hyperuricemia, kidney and liver toxicity, and leukopenia was significantly lower, but the incidence of diarrhea was significantly higher in CsA + MMF + Pred protocol than in CsA + Aza + Pred protocol (all P＜0. 01). The incidence of hyperglycemia was significantly higher (P＜0. 05), and that of hairy and gingival hyperplsia was significantly lower (P＜0. 05) in low dose Tac+ MMF+ Pred than in low dose CsA+ MMF+ Pred protocol. The incidence of hyperlipidemia in low dose CsA (or Tac)+ SRL + Pred was significantly higher than in CsA (or Tac)+ MMF+ Pred protocol (P＜0. 05). The incidence of hirsutism in low dose Tac + SRL + Pred was significantly lower than that in CsA + SRL + Pred protocol (P ＜ 0. 05). The incidence of hyperglycemia in low dose Tac + SRL + Pred was significantly higher than that in low dose CsA + SRL + Pred protocol. Conclusion The triple drug protocol with a low dose of CsA (or Tac)+ MMF+ Pred significantly improved the survival of renal transplant recipients and graft, and reduced the incidence of adverse reactions, especially Tae + MMF + Pred protocol. Adjustment of the immunosuppressant dosage and protocol, improvement of eating habits, exercise, reduction of blood pressure, reduction of blood lipid, and control of blood glucose were particularly important in preventing and controlling adverse reactions during kidney transplantation.
