Abstract: Objective　To analyze the laboratory indexes of patients infected with malaria patients and COVID-19, so as to provide reliable evidence for the diagnosis of mixed infection of both. Methods　The routine clinical laboratory items such as routine blood, biochemistry and lymphocyte subsets were tested in three cases of COVID-19 complicated with falciparum malaria who admitted to Guangzhou Eighth People's Hospital Affiliated to Guangzhou Medical University from July to December 2020 were tested. Laboratory data were stage-wise analyzed in conjunction with changes in the course of disease. Results　Three patients confirmed COVID-19 infection recruited all had malaria infection history. Fever, headache, and other symptoms emerged on the 4rd to 11th day after admission. Malaria parasite was detected by malaria parasite antigen testing and blood smear testing, and all three patients had re-ignition of malaria after being confirmed COVID-19 infection. In the early stage of malaria relapse, lymphocytes decreased, CRP and SAA increased, and gradually returned to normal level after antimalarial treatment. Interestingly, we only found one patient at the initial stage of malaria detection showed PLT decreased, no other unnormal changes in other routine blood results (WBC, ESO) and liver function results (ALT, AST, GGT, TBIL, DBIL, CG) were found from the beginning to end course of the disease. Conclusion　COVID-19 infection may promote the resurgence of malaria, so the relapse of malaria should be monitored especially for the patient with malaria infection history who begin to develop fever and other symptoms a few days after the diagnosis of COVID-19. The inflammatory indicators would be worth able as an auxiliary judgment basis for the effective treatment of the two combined infection.

OBJECTIVEIn vitro enzymatic degradation of carboxymethy konjac glucomannan (CMKGM) were studied to evaluate the feasibility of CMKGM used as carrier materials to prepare colon-specific drug delivery systems.

METHODThe solutions with rat gastrointestinal tract (GIT) contents or with commercial enzymes were chosen to stimulate in vivo GIT environment, respectively. Enzymatic degradation of CMKGM were studied by viscometic procedure. Degradation kinetics of CMKGM and konjac glucomannan (KGM) by enzymes, the effects of the degree of substitution (DS) of CMKGM and the pH of solution on its susceptibility to degradation were investigated.

RESULTCMKGM were degraded mainly in the simulated cecal and colonic media, but not in the simulated gastric and enteric media. Degradation of KGM and CMKGM by enzymes obeyed Michaelis-Menton kinetics. CMKGM with lower DS were more susceptible substrates. CMKGM were more susceptible substrates in solution with pH 6. 0-6. 8.

CONCLUSIONCMKGM had colon-specific enzymatic degradation characteristics and could be used as carrier materials to prepare colon-specific drug delivery systems.

OBJECTIVETo investigate the diagnostic value of serum islet autoantibody-glutamic acid decarboxylase antibody (GADA) and islet cell antibody (ICA) in patients with hepatogenic diabetes.

METHODSSerum GADA and ICA were measured with enzyme-linked immunosorbent assay (ELISA) in 217 patients with chronic hepatitis B (CH) or liver cirrhosis (LC). The positivity rate of GADA and ICA in different phases of CH and LC and their relations with diabetes mellitus were analyzed.

RESULTSThe positivity rate of the islet autoantibody in the circulation was 72% in CH and LC patients with diabetes mellitus and 30% in patients with normal glucose level, showing significant difference between the two patient groups (Chi2=36.620, P=0.000). CH patients with diabetes had much higher positivity rate for the antibody [52% than type 2 diabetic patients with liver dysfunction [8%, P<0.05]. The positivity rate was also much higher in CH and LC patients with lowered C peptide level [70%] than in those with normal C peptide level [40%, P<0.005].

CONCLUSIONBoth GADA and ICA have important value in the diagnosis of hepatogenic diabetes and may serve as indexed in laboratory test for distinguishing hepatogenic diabetes from type 2 diabetes.

OBJECTIVETo explore the immune mechanism of moxibustion on protecting gastric mucosa injury.

METHODSForty healthy SD rats were randomly divided into four groups: a blank group, a model group, a moxibustion acupoint group and a moxibustion non-acupoint group, 10 rats in each one. Eight days before model establishment, moxibustion at "Zusanli" (ST 36), "Zhongwan" (CV 12), "Guanyuan" (CV 4), "Pishu" (BL 20) and "Weishu" (BL 21) was applied in the moxibustion acupoint group while these acupoints' controlled points were selected in the moxibustion non-acupoint group, and no treatment was given in the model group, once a day in three groups for continuous 16 days. The helicobacter pylori (Hp) model was established by intragastric administration of Hp. HE staining microscopic examination was used to observe inflammation severity in gastric mucosa, and enzyme-linked immunosorbent assay (ELISA) was adapted to measure content of heat shock protein (HSP) 72, TNF-alpha and IL-1beta, and real-time quantitative PCR was used to measure the expression of TLR2 mRNA, TLR4 mRNA, CD14 mRNA and MyD88 mRNA in peripheral blood mononuclear cells, and western blot method was used to measure content of NFkappaB and IkappaBalpha in peripheral blood mononuclear cells.

RESULTSCompared with the blank group, the expression of HP could be seen in the smear of gastric mucosa by Gram's staining in the model group; the inflammation severity score was obviously increased as well as content of serum HSP 72 and TNF-alpha and IL-1beta in gastric tissue; and expression of TLR2, 4 mRNA, CD14 mRNA, MyD88 mRNA, NFkappaB was increased (P < 0.01), but the expression of IkappaBalpha was reduced (P < 0.05). After the moxibustion, the inflammation severity score was reduced in the moxibustion acupoint group, and the content of serum HSP 72 was increased, and the expression of TNF-alpha and IL-1beta in gastric tissue and expression of TLR2 mRNA, TLR4 mRNA, CD14 mRNA, MyD88 mRNA and NFkappaB were reduced (P < 0.01), but the expression of IkappaBalpha was increased (P < 0.05). The differences between the moxibustion non-acupoint group and the model group were not significant (P > 0.05).

CONCLUSIONThe pretreatment of moxibustion at acupoints could induce the over expression of serum HSP 72. By combining TLR 2 and 4 receptors to trigger receptor signal transduction pathways, the releases of downstream signal substances are regulated; as a result, the releases of related immune substances are regulated to relieve the gastric mucosa injury of rats with HP gastritis.

The effects of two different sample labeling methods on background signal intensities for high-density 60mer oligonucleotide microarray were investigated. Peripheral blood samples from five disease and five control subjects were collected. Total RNA targets from peripheral blood mononuclear cells were extracted and labeled with RD-PCR protocol, which were hybridized to Agilent Human 1B oligonucleotide microarrays in a two-color comparative format. The positive control targets were labeled with the directly incorporated fluorescently-labeled dNTP labeling. The SPSS program was performed to test normality of the dataset, variance homogeneity between the groups, coefficients of variation (CV) and analysis of variance. The results showed that the background signal intensities of Cy3 channel were higher than those of Cy5 channel. The differences of background signal intensities between the RD-PCR approach and the directly incorporated fluorescently-labeled dNTP labeling were extremely significant (P- Cy3

Plasma obestatin level was determined in patients with impaired glucose regulation and type 2 diabetes mellitus.The plasma obestatin levels in patients of both groups were significantly decreased as compared with that in controls.Plasma obestatin level was negatively correlated with body mass index,HbA_(1C),waist-to-hip ratio,plasma insulin and HOMA-IR.Obestatin level seems to be related with metabolic disorder.
