Objective:To detect the correlativity between clinical periodental indexes and C-terminal telopeptides of type I collagen (CTX)concentration in gingival crevicular fluid(GCF).Methods:77 teeth with periodontitis in 60 patients from the international Bethune peace hospital were included.The concentration of CTX in GCF was detected by enzyme-linked immunosorbent assay.The plague indexe(PL),gingival indexe(GI),probing depth(PD)and attachment loss (AL)level were recorded at clinic.The correla-tion of CTX concentration and clinic indexes was analysed by Kruskal-Wallis test using SPSS 1 1 .0 software.Results:The Spearman correlation coefficient of PL,GI,PD and AL with CTX was 0.386(P <0.01 ),0.366(P <0.05),0.382(P <0.05)and 0.31 4(P <0.05)respectively.Conclusion:PL,GI,PD and AL are positively correlated with the concentration of CTX in GCF(P <0.05).

Objective To investigate the correlation of plasma heme oxygenase-1 (HO-1) level and type 2 diabetes mellitus (T2DM). Methods The outpatient with type 2 diabetes mellitus (T2DM) undergoing oral glucose tolerance test and healthy individuals with physical examination were divided into T2DM group and healthy control group, the differences between the two groups in HO-1 and methane dicarboxylic aldehyde (MDA), mean fluorescence intensity (MFI), homeostasis model assessment of insulin resistance (HOMA-IR) and fasting blood glucose (FBG) were comparatively analysed , and analyzed the correlations between HO-1 and reactive oxygen species (ROS) MFI, MDA, HOMA-IR and FBG. Results The type 2 diabetes group in MDA and MFI, the expression rate of HO-1 were higher than those of control group (P<0.05), correlation analysis of expression of HO-1 was positively correlated with MFI, MDA (r=0.489, 0.763, P<0.05) in the T2DM group, HO-1, HOMA-IR and FBG were significantly higher than the healthy control group, the difference was statistically significant(P<0.05). The expression of HO-1 and HOMA-IR and FPG levels were positively correlated in the T2DM group (r=0.271, 0.426, P <0.05). Conclusion T2DM patients with hyperglycemia and oxidative stress, plasma HO-1 expression is significantly increased, HO-1 is related to oxidative stress, insulin resistance and hyperglycaemia, which has certain value on clinical assessment of T2DM and therapeutic efficacy.

ObjectiveTo analyze literature on acupuncture-related adverse events published in periodicals in Science Citation Index (SCI) and Medllars Online(Medline).MethodsWe searched the Web of Science database and the Medline database to identify articles about the safety of acupuncture therapy.Case reports,case series,surveys and other observational studies were included if they reported factual data,but review articles,translations and clinical trials were excluded.ResultsFindings:The inclusion criteria were met by 232 articles that in total reported on 389 cases of adverse events after acupuncture.Conclusion Acupuncture therapy is relatively safe,most acupuncture-related adverse events can be avoided by standardized clinical practice.Establishment of acupuncture medical safety standard system is extremely urgent.

Randomized controlled trials (RCT) is the source of the raw data of evidence-based medicine. Blind method is adopted in most of the high-quality RCT. Sham acupuncture is the main form of blinded in acupuncture clinical trial. In order to improve the quality of acupuncture clinical trail, based on the necessity of sham acupuncture in clinical research, the current situation as well as the existing problems of sham acupuncture, suggestions were put forward from the aspects of new way and new designation method which can be adopted as reference, and factors which have to be considered during the process of implementing. Various subjective and objective factors involving in the process of trial should be considered, and used of the current international standards, try to be quantification, and carry out strict quality monitoring.

Aim To study and compare the pharmaco-kinetic parameters of roxithromycin under normoxic and hypoxic rats. Methods A highly effective and rapid ultra-performance liquid chromatography with tandem mass spectrometry ( UPLC-MS/MS) method with posi-tive electrospray ionization source was successfully de-veloped and validated for quantification of roxithromy-cin in rat plasma. Sprague-Dawley rats were randomly divided into the hypoxia and normoxic groups. Each rat obtained a single dose of roxithromycin with 10 mg · kg-1 via intragastric administration. The pharmacoki-netic parameter comparison between normoxic and hy-poxic groups was calculated by SPSS software using in-dependent sample t test method. Results The main pharmacokinetic parameters of roxithromycin between the normoxic and hypoxic rats were:the AUC(0-t) 7 576 and 3 761 μg·h·L-1 , MRT(0-t) 5. 6 and 7. 7 h, T1/2 3. 4 h and 3. 9 h, CL 1. 5 and 3. 0 L · h-1 · kg-2 , tmax3. 1 and 3. 4 h, Cmax 1 116 and 372 μg·L-1 , re-spectively. The levels of Cmax and AUC of roxithromy-cin in hypoxic rats were statistically lower than those in normoxic rats. Conclusion The exposure level of rox-ithromycin in hypoxic rats markedly decreased. Our re-sults may provide an important experimental basis to adjust the dosage for roxithromycin in hypoxic clinical practice.

Objective:To evaluate the value of vasoactive-inotropic Score (VIS) at different time points in predicting the 28-day mortality of patients with septic shock, so as to reduce the risk of death and improve the prognosis of patients.Methods:This experiment was a single-center retrospective cohort study. The clinical data of 275 adult patients with septic shock who were treated with vasoactive drugs in the intensive care unit of the Affiliated Hospital of Xuzhou Medical University from February 2016 to February 2020 were collected. According to the 28-day survival condition, all recruited patients were divided into the death group and the survival group, and the maximum vasoactive-inotropic score of all patients at the first 24 h and the second 24 h were calculated, which were expressed as VIS max24 and VIS max48. Multivariate logistic regression analysis was used to find the independent risk factors that influencing the prognosis. The receiver operating characteristic curve was used to analyze the predictive value of VIS. Results:There was no significant difference between the death group and the survival group in the characteristics including age, sex, weight, infection sites, blood culture results, cardiac arrest, hormone use, and 24 h rehydration volume ( P>0.05). APACHE II score, basic lactic acid, and lactic acid after 24 h of treatment were increased significantly in the death group ( P<0.05). VIS max24 could accurately predict the 28-day mortality (AUC=0.953, 95% CI: 0.924-0.982), which were more efficent compared to VIS max48 (AUC=0.919, 95% CI: 0.881-0.957), basic lactic acid (AUC=0.937, 95% CI: 0.900-0.966) and APACHEⅡ score (AUC=0.865, 95% CI: 0.818-0.913). Conclusion:VIS max24 can more accurate predict the 28-day mortality in patients with septic shock.

The extracting technology of salidroside, tyrosol, crenulatin and gallic acid from Rhodiolae Crenulatae Radix et Rhizoma was optimized. With extraction rate of salidroside, tyrosol, crenulatin and gallic acid as indexes, orthogonal test was used to evaluate effect of 4 factors on extracting technology, including concentration of solvent, the dosage of solvent, duration of extraction, and frequency of extraction. The results showed that, the best extracting technology was to extract in 70% alcohol with 8 times the weight of herbal medicine for 2 times, with 3 hours once. High extraction rate of salidroside, tyrosol, crenulatin and gallic acid were obtained with the present technology. The extracting technology was stable and feasible with high extraction rate of four compounds from Rhodiolae Crenulatae Radix et Rhizoma, it was suitable for industrial production.
