Abstract: Objective　To investigate the prevalence and genetic characterization of Blastocystis in primary and middle school students in Baisha Li Autonomous County, Hainan Province, in order to understand the infection status of Blastocystis and its subtype distribution characteristics in this area. Methods　From March to November 2021, fecal samples were collected from two primary and middle schools in Baisha Li Autonomous County. Nested PCR targeting the SSU rDNA was employed in this study, sequence analysis were performed to determine the prevalence and subtype. A neighbor-joining tree was built using Mega 7. Meanwhile, the risk factors of the Blastocystis infection among different grades and genders were evaluated. Results　The infection rate of Blastocystis was 4.1% (13/314), there was no statistical difference in infection rates among genders and grades (P>0.05). Sequence analysis revealed that three Blastocystis subtypes were identified, namely ST3 (n=7), ST7 (n=4) and ST1 (n=2), all of which have zoonotic potential. Conclusions　This is the first report of the identification of Blastocystis in humans in Hainan at the subtype level, and provide the basic data for the prevention and control of Blastocystis in this area. The zoonotic subtypes identified in this area indicated more studies should be taken in humans and various animals, to better evaluate the transmission of Blastocystis and provide scientific support for the prevention and control of Blastocystis.

A total of 180 type 2 diabetic patients with negative anti-thyroid autoantibodies were recruited.According to the levels of serum 25-OH vitamin D [25 (OH) D],these patients were divided into four groups:sufficient group (≥ 30 ng/ml),insufficient group (20-＜30 ng/ml),deficiency group (10-＜20 ng/ml),and severe deficiency group(＜ 10 ng/ml).The results showed that compared with sufficient vitamin D group,the group with severe deficient vitamin D had higher TT3,FT3,FT3/FT4,and TSH (all P＜0.05).The serum 25(OH) D level was negatively correlated with TSH values (r =-0.207,P＜0.05) after adjustment for gender,age,and body mass index.Multivariate regression analysis indicated that serum 25 (OH) D level was an independent influencing factor for TSH value (β =-0.201,P＜0.05),suggesting that serum 25 (OH) D level seems to be correlated with thyroid function in type 2 diabetic patients.

The aim of this study was to investigate and evaluate the antitumor effects of a novel poly(ADP-ribose) polymerase (PARP) 1/2 inhibitor, YHP-836, in combination with temozolomide (TMZ) for the treatment of glioblastoma (GBM). The cytotoxicity of YHP-836 was tested alone or in combination with TMZ using MTT assay. Immunoblotting and flow cytometry were also employed to assess the combination activity of YHP-836 and TMZ in multiply GBM cell lines. Further, the antitumor activity of YHP-836 and TMZ was evaluated using subcutaneous and orthotopic mice xenograft tumor models. All procedures were approved by the Ethics Committee for Animal Experiments of the Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College and conducted under the Guidelines for Animal Experiments of Peking Union Medical College. The approval number is 00009138. It was demonstrated that the combination of YHP-836 and TMZ increased the cytotoxicity against GBM cells and upregulated histone H2AX phosphorylation (γH2AX) expression levels compared to TMZ treatment alone. The combination also led to the S-phase cell cycle arrest. Moreover, YHP-836 significantly enhanced TMZ antitumor effects without significantly increasing chemotherapy drug toxicity in vivo, whereas YHP-836 alone showed limited therapeutic efficacy against GBM. In conclusion, the novel PARP1/2 inhibitor, YHP-836, sensitizes TMZ and provides a basis for further investigation into its mechanism of action. These findings suggest that YHP-836 may be a potential candidate for combination therapy with TMZ in patients with TMZ resistance.

cDNA for Insulin-like growth factor binding protein 3 was cloned and constructed a prokaryotic expression vector--pET-DsBA-IGFBP3. The construct was transformed into E. coli BL21 (DE3)plysS. The induced fusion protein (D-IGFBP3) was expressed successfully in soluble form. We obtained D-IGFBP3 the purify of which is over 95% after purification by His affinity chromatography. The product was identified by Western-blot. The cell assay showed that the obtained fusion protein can inhibit the growth of MCF-7 and bind with IGF-I in vitro.

OBJECTIVETo provide a scientific basis for systematic research on the mechanism of chronic immobilization stress (CIS) induced metabolic network change in rats, through detecting the changes of endogenous metabolites in rats with CIS, treated or un-treated with Xiaoyao Powder (XYP), for determining the small molecule marker compound that closely associated with the metabonomical specificity of CIS and acting mechanism of XYP.

METHODSThirty-six experimental male SD rats were divided into 3 groups, the normal control group, the model group and the XYP group. And all the three groups were subdivided into two subgroups respectively on day 7 and day 21 of the experiment. The stress rat model of CIS was made by chronic restraining method for 3 h every day. Starting from the first day of modeling, XYP 3.854 g/kg in volume of 1 mL/100 g body weight was administered 1 h before restraining via gastrogavage to rats in the XYP group, while equal volume of distilled water was given to rats in the other two groups instead. Blood samples were collected on the 8 th day and 22 th day for detection in the following procedure: at 27 degrees C, 300 microL supernate of blood plasma was taken, calling the Carr-Purcell-Meiboom-Gill (CPMG) and longitudinal eddy-delay (LED) sequence respectively on a Fourier variable nuclear magnetic resonance (NMR) spectrometer, pre-saturated inhibition of the water peak was performed; free induction decay (FID) signals were transferred via 32 k Fourier transformation to gain one-dimensional NMR spectrogram; by taking TSP as the chemical migration reference peak, the segmental integral calculus (0.04 ppm per segment) was performed from 4.5 - 0.5 ppm (CPMG) and 6.0 - 0 ppm (LED) within the peak ranges in 1H spectra using the VNMR software; after normalization, centering and scaling were conducted on data, then used for pattern recognition of principal component analysis (PCA) using the SIMCA-P 10.0 software, or if necessary, the partial least squares discriminate analysis (PLS-DA) was performed.

RESULTS(1) The metabolites in the model group were significantly different from those in the control group, suggesting that the animal model was successfully established with the metabolic network different to that of control. The model group and the XYP group could be differentiated from the control group by the differences of metabolites and metabolic networks between groups; XYP could intervene the metabolites or the metabolic path to cause changes in final metabolites. (2) The serum contents of lactic acid (1.4, 4.16), choline (3.24), N-acetylgalactosamine (NAC) and saturated fatty acids (1-3) increased, but unsaturated fatty acids (1.99,4-5), blood sugar (34), HDL (0.83), etc. reduced in the CIS rats. XYP showed obvious regulatory effects on final metabolites, causing decrease of lactic acid, choline, NAC, saturated fatty acids and blood sugar, and increase of unsaturated fatty acids, blood sugar, HDL, 3.44 ppm compound, etc.

CONCLUSIONSThe metabolic phenotype in CIS rats includes the increase of lactic acid, choline, NAC, saturated fatty acid, and the decrease of blood sugar contents, unsaturated fatty acid, HDL, 3.44 ppm compound, etc., these may be the markers of the metabolites. The final metabolites changes induced by CIS are primarily the lipid substances. XYP markedly regulates the contents of final metabolites, showing the regulatory effects on final metabolites, but what is the metabolite or metabolic pathways it interferes to alter the final metabolites should be confirmed by further studies.
