Objective To explore the therapeutic effect and influencing factors of individualized exercise under continuous glucose profile in patients with typ 2 diabetes mellitus(T2DM).Methods A total of 110 patients with T2DM who were treated in the Department of Endocrinology of our hospital from December 2021 to July 2022 were randomly divided into conventional group and personalized group,with 55 cases in each group.The conventional group was given routine health exercise guidance,the personalized group was given a personalized exercise program.Repeated measurement analysis of variance was used to evaluate the improvement of blood glucose related indicators in the two groups at 3 and 6 months after intervention.Logistic regression was used to analyze the influencing factors of blood glucose(BG)control after 6 months of intervention.Results After 3 and 6 months of intervention,FBG,2 hBG,hemoglobin A1c(HbA1c),mean blood glucose(MBG)and time above target range(TAR)in the personalized group and conventional group were all lower than those before intervention(P<0.05).Time in range(TIR)of glucose within 24 h was higher than that before intervention(P<0.05).After 3 and 6 months of intervention,FBG,2 hBG,HbA1c,MBG and TAR in the personalized group were lower than those in the conventional group at the same time point(P<0.05),and TIR was higher than that in the conventional group at the same time point(P<0.05).After 6 months of intervention,the BG control rate in the personalized group was higher than that in the conventional group(P<0.05).Logistic regression analysis showed that the DM duration,exercise intervention methods and TIR were the influencing factors of BG control.Conclusions Exercise guidance is an effective intervention method to control diabetes.Compared with conventional exercise guidance,personalized exercise program has a better effect on controlling patients'BG level,and has a better effect on patients with short course of disease.

Objective To study the effect of alprostadil combined with epalrestat and methylcobalamin in the treatment of type 2 diabetic peripheral neuropathy.Methods From January 2014 to June 2016,120 patients with type 2 diabetic peripheral neuropathy in the First People's Hospital of Baiyin were randomly divided into two groups according to the random number table method.64 patients of the observation group were given the treatment of alprostadil,epalrestat combined with methylcobalamin.56 patients of the control group were given the treatment of alprostadil and methylcobalamin.And the two groups were treated for 4 weeks.The blood glucose,clinical symptoms,adverse reaction,nerve conduction velocity index were compared between the two groups before and after treatment.Results The fasting blood glucose and 2-hour postprandial blood glucose of the two groups after treatment were significantly decreased (t =18.20,17.61,15.75,23.69,all P ＜ 0.05),and the conduction velocity of the common peroneal nerve,the median nerve and the ulnar nerve in the observation group were significantly higher than those in the control group (t =1.989,2.638,3.026,2.187,2.619,1.997,all P ＜ 0.05).The total effective rate of the observation group was significantly higher than that of the control group(95.3％ vs.82.1％,x2 =4.54,P ＜0.05).There were no statistically significant differences in the blood glucose and the incidence rate of adverse reactions between the two groups (t =0.267,0.176,0.695,0.658,x2 =1.356,all P ＞ 0.05).Conclusion Alprostadil combined with epalrestat and methylcobalamin in the treatment of type 2 diabetic peripheral neuropathy has good effect.

OBJECTIVETo explore the molecular basis for a CD36 deficiency individual and distribution of CD36 gene mutation in Guangxi population.

METHODSA female individual was studied. CD36 phenotype was detected by monoclonal antibody immobilization of platelet antigens assay (MAIPA) and flow cytometry (FCM). The coding regions of the CD36 gene were sequenced. A DNA-based polymerase chain reaction-sequence specific primer (PCR-SSP) assay was used to verify the identified mutation. Cell lines expressing the mutant and wild-type CD36[CD36(MT) and CD36(WT)] were established, with the expression of CD36 determined by Western blotting. The distribution of CD36 gene mutation was investigated among 1010 unrelated individuals with the PCR-SSP assay.

RESULTSBoth MAIPA and FCM assays showed that the patient had type II CD36 deficiency. DNA sequencing showed that she has carried a heterozygous mutation T538C (Trp180Arg) in the exon 6 of CD36. Sequencing of cDNA clone confirmed that there was a nucleotide substitution at position 538 (538T>C). Western blotting also confirmed that the CD36 did not express on the CD36(MT) cell line that expressed the 538C mutant, but did express on the CD36(WT) cell line. The novel CD36 mutation T538C was further verified with 100% concordance of genotyping results by DNA-based PCR-SSP assay and 1010 unrelated individuals. No CD36 538C allele was detected among the 1010 individuals.

CONCLUSIONThis study has identified a novel CD36 mutation T538C(Trp180Arg)(GenBank: HM217022.1), and established a genotyping method for the novel sequence-specific primer PCR. The novel mutation is rare in Guangxi and can cause type II CD36 deficiency.

Objective To investigate the effect and clinical application of two kinds of endoscopic titanium clip in treatment of iatrogenic or iatrogenic perforation of duodenal descending part. Methods For 15 cases of perforation of duodenal descending part, according to the specific location of the perforation, select different endoscopic, compare the closing efficiency and success rate. Results 8 cases closed under gastroscopy in 15 cases of descending part of duodenum perforation, successfully closed in 7 cases, success rate was 87.5 %; 7 cases closed under duodenoscopy, successfully closed in 7 cases, the success rate 100.0%. 14 cases successfully closed by endoscopic titanium clip in 15 cases, 1 case failed, the success rate was 93.3 %. The effective titanium clip quantity, invalid (loss) titanium clip quantity and the closing time between the two groups has no statistically significance (P > 0.05). Conclusion It is safe and effective to use two kinds of endoscopic titanium clips in treatment of iatrogenic or iatrogenic duodenal per-foration.

Objective To establish the platelet antigen panel cells and to apply them in the detection and identification of platelet alloantibody.Methods Human platelet antigen(HPA)1-16 genotyping from 1 500 un-related blood donors in Nanning area were performed by the polymerase chain reaction-sequence specific primers(PCR-SSP)technique,platelet antigen cells with O blood type were chosen to establish the panel cells of platelet antigen.The phenotype of the panel cells were verified by the reference sera from the 14th platelet immunology workshop of the International Society of Blood Transfusion(ISBT).And then these panel cells were used in clinic to detect the platelet alloantibody and the samples from the 14th and 15th platelet immunology workshop of ISBT.Re-sults Six platelet cells with consistent phenotype and genotypes and covering the HPA 1-5 and 1 5 systems were selected to estab-lish the platelet panel cells and successfully applied them in the clinical and scientific sample detection and identification.Conclusion Platelet antigen panel cells are established successfully,which provides the experimental basis for the diagnosis and research of platelet allogenic abnormal immunity diseases.

Sperm-mediated gene transfer (SMGT) is one of the most methods in the transgenic animal research and the efficiency of spermatozoa binding and internalization exogenous DNA after sperm/DNA co-culture is important to a successful SMGT.In this study,the influencing factors of exogenous DNA uptake by spermatozoa were detected using DIG labeled EGFP as exogenous gene.The results demonstrated that porcine spermatozoa could spontaneously take up exogenous DNA which mainly binding occurs on the sub-acrosomal and nuclei region of the sperm head.The rate of spermatozoa binding exogenous DNA increased with the extending action of time.At 37℃ and 39℃,the rate of spermatozoa uptake exogenous DNA would not increase after 60 min incubation,and the similar result was observed on 90 min at 17℃.Binding rates and internalization rates of washed ejaculated sperm cells from the 15 boars varied between 6.57%-35.81% and 2.990%-24.66%,respectively.The binding rate and intemalization rate were mostly inhibited by seminal plasma.The binding rates were significantly increased by liposome and DMSO,respectively.Dead-spermatozoa could bind exogenous DNA,the intermalization process could not be completed.Furthermore,the highest binding rate was found in membrane broken spermatozoa as a result of freeze-thawing and this was independent of the sperm donors.
