This study was to evaluate the effect of individualized health education on blood glucose control in type 2 diabetic(T2D)Patients.Two hundred and thirty-eight T2D patients were randomly received individualized diabetes education(intervention group)or general education(control group).At 48 week,change of blood glucose control from baseline was observed.The blood glucose level and HbA1c in the intervention group were lower than those in the control group[(7.1±0.8)vs (9.3±6.5)mmol/L,(7.0 ±1.3)%vs(8.0%±1.0)%;P＜0.05].Thus,individualized diabetes education might be helpful for blood glucose control in T2D patients.

As a large family of hydrolases, GTPases are widespread in cells and play the very important biological function of hydrolyzing GTP into GDP and inorganic phosphate through binding with it. GTPases are involved in cell cycle regulation, protein synthesis, and protein transportation. Chaperones can facilitate the folding or refolding of nascent peptides and denatured proteins to their native states. However, chaperones do not occur in the native structures in which they can perform their normal biological functions. In the current study, the chaperone activity of the conserved GTPases of Escherichia coli is tested by the chemical denaturation and chaperone-assisted renaturation of citrate synthase and α-glucosidase. The effects of ribosomes and nucleotides on the chaperone activity are also examined. Our data indicate that these conserved GTPases have chaperone properties, and may be ancestral protein folding factors that have appeared before dedicated chaperones.

At present,the network media reports of Chinese medical disputes appeared blowout growth,and also brought the loss of propriety,the loss of balance,the loss of justice and other ethical issues while it played the role of public opinion supervision in the medical disputes.In view of these,from the concept definition of ethics anomie in network media report of medical disputes,this paper analyzed and interpreted the ethics anomie in network media report of medical disputes,pointed out existing problems and further put forward creating the network media professional ethics norms,establishing a social supervisory system which integrates self-discipline and heteronomy,building a doctor-patient docking platform and other perfecting countermeasures.

OBJECTIVE To investigate the effect of Jiawei Tianwang Buxin Dan(JWBXD)on insomnia in rats exposed to simulated high-altitude conditions.METHODS ① Thirty SD rats were randomly divided into the normal control,model,model+Jiawei Tianwang Buxin Dan(JWBXD,9.6 mg·kg-1),model+Tianwang Buxin Dan(TWBXD,9.6 mg·kg-1),and model+diazepam(DZP,3 mg·kg-1)groups.Rats,except for the normal control group,were subjected to a low-pressure,low-oxygen animal experimental chamber simulating a 5000 m altitude.Respective drugs were ig administrated once daily at 9:00 for seven days,and signal acquisition and sleep analysis were conducted by a wireless physiological sig-nal telemetry system.②Forty rats were randomly divided into five groups as described in ①.Through-out the experiment,the general condition and body mass of the rats were observed daily.Drug adminis-tration lasted for seven days,and grip strength was tested one hour after the final administration.ELISA was used to measure the levels of corticotropin-releasing hormone(CRH),adrenocorticotropic hor-mone(ACTH),corticosterone(CORT),and melatonin(MLT)in serum.Western blotting was performed to measure the expression levels of core clock proteins period circadian regulator 2(Per2),circadian locomotor output cycles(Clock),cryptochrome 2(Cry2),brain-muscle arnt-like protein 1(Bmal1),nuclear receptor subfamily 1,group D member 1(NR1D1),glycogen synthase kinase-3β(GSK-3β),as well as acetylserotonin O-methyltransferase(ASMT)in the hypothalamus and pineal gland,respectively.RESULTS ① Compared with the normal control group,the model group exhibited a decrease in total sleep time(P<0.01),an increase in wakefulness(P<0.01),a significant reduction in slow wave sleep(SWS)(P<0.05)and the mean bouts duration(P<0.05).Compared with the model group,both DZP and JWBXD(P<0.01)prolonged sleep time and suppressed wakefulness(P<0.01)in the hypoxic envi-ronment.DZP and JWBXD prolonged SWS(P<0.05,P<0.01),while TWBXD had no significant effect.JWBXD improved the mean bouts duration of SWS in the model rats(P<0.01),whereas no such improvement was observed in model+DZP and model+TWBXD groups.② Compared with the normal control group,the model group showed a significant decrease in forelimb grip strength(P<0.01),increased levels of serum ACTH(P<0.05),CRH,and CORT(P<0.01),and decreased MLT levels(P<0.05).The expression levels of Per2,Cry2,GSK-3β,and NR1D1 in the hypothalamus were downregu-lated(P<0.05,P<0.01),while Bmal1 and Clock were upregulated(P<0.05,P<0.01).ASMT expression in the pineal gland was decreased(P<0.05).Compared with the model group,JWBXD and TWBXD enhanced forelimb grip strength(P<0.01),reduced serum CORT and ACTH levels(P<0.05),decreased CRH levels(P<0.01),and restored MLT levels(P<0.01).JWBXD upregulated the expression levels of Per2,Cry2,GSK-3β and NR1D1 in the hypothalamus(P<0.05,P<0.01),but downregulated Bmal1 and Clock expression(P<0.05,P<0.01).TWBXD downregulated Bmal1 expression in the hypothalamus(P<0.01)and increased NR1D1 expression(P<0.05).DZP significantly enhanced the expression levels of Per2,Cry2 and NR1D1 in the hypothalamus(P<0.01).JWBXD,TWBXD and DZP improved ASMT expression in the pineal gland(P<0.05).CONCLUSION JWBXD can improve sleep structure and prolong the duration of SWS in rats exposed to simulated high-altitude conditions.The mechanisms may involve the regulation of core clock protein expressions in the hypothalamus,promotion of mela-tonin secretion,and inhibition of HPA axis hyperactivity.

ObjectiveTo investigate the menstrual conditions of women infected with COVID-19 in Shanghai and analyze the influencing factors. MethodsFrom December 2022 to March 2023， menstrual data from 281 women infected with COVID-19 in Shanghai were collected with a questionnaire survey， including usual menstrual characteristics， the most recent menstrual period post-infection， symptoms of infection， and medication usage. According to the crossover period between the menstrual period and the infection period of the respondents， the samples were divided into two groups for comparative analysis： those whose menstrual and infection periods overlapped （positive group） and those whose menstruation started after conversion to virus-negative （negative conversion group）. ResultsAmong the 281 respondents， 196 （65.8%） experienced menstrual changes. Among them， 145 （51.6%） had changes in menstrual volume， color and texture， and 109 （38.8%） had changes in menstrual duration or cycle. Decreased menstrual volume （22.1%）， darker color （23.49%）， thicker texture （21.0%）， increased blood clots （16.7%）， and prolonged duration （21.8%） were observed in both groups. The rate of changes in menstrual volume， color， and texture was higher in the positive group （56.8%， 69/110） than that in negative group （37.3%， 76/171） （P<0.05）. Regarding the menstrual cycle changes， the rate of early onset was higher in the positive group （14.5%） compared to the negative conversion group （3.5%）（P<0.05）， while the rate of delayed menstruation was higher in the negative conversion group （25.1%） than that in the positive group （5.5%） （P<0.05）. Correlation analysis showed a weak association between sore throat and menstrual changes （r=0.154， P<0.05）. ConclusionSome women infected with COVID-19 experience short-term changes in their menstrual conditions， characterized by reduced volume， darker color， thick texture， increased clots， and prolonged menstrual duration， reflecting a pathogenesis of blood stasis. Menstruation during the infection period tends to occur earlier， while delayed menstruation is more prevalent at post-conversion.
