ABSTRACT

OBJECTIVE To establish the fingerprint of Zhuang medicine Jinmu granules and carry out chemometric analysis , and determine the contents of three components . METHODS High performance liquid chromatography (HPLC) method was adopted. Using rutin as the reference ,HPLC fingerprints of 10 batches of Jinmu granules were drawn and similarity evaluation was performed by Similarity Evaluation of Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition);the common peak was determined by comparing with mixed control ;SPSS 21.0 software was used for cluster analysis ,and SIMCA 14.1 software was used for principal component analysis and orthogonal partial least squares-discriminant analysis. The differential components affecting the quality of Jinmu granules were screened by taking the variable importance in projection (VIP)value >1 as the standard ;the HPLC method was used to determine the contents of astilbin ,polydatin and berberine hydrochloride in Jinmu granules. RESULTS There were 22 common peaks in 10 batches of Jinmu granules ,and the similarities were 0.962-0.997;five common peaks were identified ,namely gallic acid (peak 2),polydatin(peak 9),rutin(peak 11),astilbin(peak 13)and kaempferol (peak 20). The results of cluster analysis showed that 10 batches of Jinmu granules could be clustered into 3 categories:S1 and S 3-S4 were grouped into one category ;S5-S6 and S 9 were grouped into one category ;S2,S7-S8 and S 10 were grouped into one category. The results of principal component analysis showed that the parameter of model interpretation was 0.951 and that of prediction ability was 0.723. The classification results were basically consistent with cluster analysis. The classifica tion results of orthogonal partial least squares- com discriminant analysis were also ba sically consistent with clus- ter analysis. The common peaks with VIP value >1 in the order were peak 7>peak 11(rutin)>peak 17>peak 13(astilbin)> peak 3>peak 8>peak 6>peak 16 respectively. The linear ranges of astilbin ,polydatin and berberine hydrochloride were 0.012 6- 1.225 0,0.010 8-1.052 5 and 0.020 0-1.562 5 mg/mL,respectively(all R 2=0.999 9). RSDs of precision ,stability(24 h)and repeatability tests were all less than 3%. The average recoveries were 99.48%(RSD=2.67%,n=9),98.57%(RSD=1.77%,n= 9)and 100.84%(RSD=2.49%,n=9). The contents were 1.221 0-7.011 6,2.251 1-4.462 9,1.252 4-3.328 7 mg/g,respectively. CONCLUSIONS Established fingerprint and the method of content determination are accurate ,stable and simple. Combined with chemometric analysis ,it can be used for the quality control and evaluation of Zhuang medicine Jinmu granules.

ABSTRACT

OBJECTIVE@#To explore the epidemiologic characteristics of acupuncturists who are sensitive to stimulation of moxa smoke, which could provide further direction for safety protection of exerting moxibustion and to further verify the feasibility of internet survey.@*METHODS@#A self-made questionnaire regarding body response to moxa smoke was established, which was used to conduct a face-to-face survey among acupuncturists who had performed long-term moxibustion. The Logistic regression model was used to analyze the factors affecting the stimulation response of acupuncturists and the epidemiological characteristics of acupuncturists was obtained.@*RESULTS@#A total of 733 valid data was obtained. The multivariate Logistic regression analysis showed that the history of chronic respiratory disease was the main risk factor of stimulus response including cough, phlegm in the throat, asthma, dyspnea, shortness of breath and nasal dryness after exposure to moxa smoke (<0.05, <0.01). The risk of stimulus response such as cough, tearing and nasal dryness was higher in women than in men (<0.05, <0.01). The risk of dry eyes and eyes pain in smokers was higher than those in non-smokers (<0.05). The risk of shortness of breath in those who were exposed to second-hand smoke was higher than those who were not exposed to second-hand smoke (<0.05). The analysis of index trend line showed that the results of internet survey were similar to those of face-to-face survey.@*CONCLUSION@#The stimulus response of acupuncturist after long-term exposure to moxa smoke is related to the history of chronic respiratory disease, being female, smoking or exposure of second-hand smoke, therefore more attention should be paid to those populations. In addition, the internet survey can be used for the epidemiological investigation of safety of moxa smoke.

ABSTRACT

Objective@#Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.@*Methods@#A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( @*Results@#Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks.@*Conclusion@#Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

ABSTRACT

Objective:To investigate the effect of electroacupuncture at Jiaji (EX-B2) points and Stomach Meridian Foot-Yang Ming points on the neurological function and the expression of local Synapsin I in rats after spinal cord injury, and to explore its molecular mechanism. Methods:A total of 60 Sprague-Dawley rats were established spinal cord injury model and they were randomly divided into normal control group, Jiaji group and Yang Ming group, with 20 rats in each group. On the third day after operation, Jiaji group and Yang Ming group were treated with electroacupuncture while the normal control group was not. Their neurological function was assessed with BBB every day. Four rats in each group were sacrificed at the end of the 1st, 2nd, 3rd, 4th and 5th week during the intervention period. HE staining was used to observe the morphology of spinal cord. Immumohistochemical staining was used to detect the expression of Synapsin I protein. Reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blotting was used to detect the content of of Synapsin I mRNA and protein. Results:The BBB scores were higher in Jiaji group and Yang Ming group than in the normal control group at all the time points (P < 0.05), and were higher in Yang Ming group than in Jiaji group from one to three weeks (P < 0.05). The immunohistochemical scores of Synapsin I protein were higher in Jiaji group than in the normal control group in the first week (P < 0.05), and were higher in Yang Ming group than in the normal control group from one to four weeks (P < 0.05). The immunohistochemical scores of Synapsin I protein were higher in Yang Ming group than in Jiaji group from three to four weeks (P < 0.05). The expression of Synapsin I mRNA and protein first increased and then decreased in the normal control group; which was higher in Jiaji group than in the normal control group in the first week (P < 0.05) and was higher in Yang Ming group than in the normal control group from one to four weeks (P < 0.05). The Synapsin I mRNA expression in the third week and the Synapsin I protein expression from two to three weeks was higher in Yang Ming group than in Jiaji group (P < 0.05). Conclusion:Electroacupuncture at both Jiaji points and Stomach Meridian Foot-Yang Ming points promote the recovery of nerve function in rats with spinal cord injury. It may be related to the elevated level of Synapsin I in the damaged parts of the spinal cord.

ABSTRACT

A sensing system based on AuNP-AuNP-UCNP triple structure for efficient detection of dual targets was constructed. In the preparation of triple structure, the gold nanoparticles (AuNPs) and upconversion nanoparticles (NaYF4: Yb, Er, Gd, UCNPs) were synthesized and surface modified. Then the two nanoparticles and their aptamers were connected to form two kinds of optical fluorescent probes. A nucleic acid sequence that matches with two aptamers was designed, rendering the probes to get close based on the principle of complementary base pairing. On the basis of this, a sensing system with a triple structure was prepared,and its connecting effect was characterized by TEM. With this system, dual targets of bisphenol A and estradiol were efficiently and conveniently detected through quantitative determination by fluorescence and UV spectrophotometer. At reaction temperature of 30℃ and pH=7.8,this method exhibited good linear range for determination of bisphenol A and estradiol from 2 ng/mL to 200 ng/mL and from 10 ng/mL to 150 ng/mL, with limits of detection of 0.2 ng/mL and 0.5 ng/mL, respectively. This sensing system with the triple structure owned better specificity to structural and functional analogues, and showed good repeatability and stability. What's more,this sensing system was applied in actual water detection,with the recoveries between 86.1% and 107. 4%, and the relative standard deviation below 6. 8%. This method showed promising applications in other environmental estrogens in water samples.

ABSTRACT

<p><b>OBJECTIVE</b>To retrospectively investigate the clinical effect of the rivet-assisted hollow screw in the treatment of posterior cruciate ligament avulsion fracture.</p><p><b>METHODS</b>Total 49 patients with knee cruciate ligament avulsion fracture in the ending point of the ligament from January 2010 to December 2014 were divided into the treatment group and the control group. Thirty-one patients in treatment group were treated with rivet-assisted double cannulate nail, including 13 males and 18 females, ranging in age from 38 to 51 years old, with a mean of (40.6±5.1) years old; according to Meyers classification, 23 cases of type 2, 8 cases of type 3; 5 patients were caused by the low energy injury and 26 patients were caused by the high energy injury. Eighteen patients in control group were treated with double gold hollow screw fixation, including 5 males and 13 females, ranging in age from 36 to 52 years old, with an average age of (4.16±4.7) years old; according to Meyers classification, 14 cases of type 2 and 4 cases of type 3;2 patients were caused by the low energy injury and 16 patients were caused by the high energy injury. The operation time, postoperative complications, fracture healing time and the last AKS scoring system were compared between the two groups.</p><p><b>RESULTS</b>All the patients were followed up, and the duration ranged from 12 to 24 months, with an average of 14.2 months. The patients in treatment group had no displacement of fracture fragments and internal fixation failure. The results of AKS score:pain was 48.1±1.5, activity was 21.3±2.7, stability was 20.9±2.5, walking ability was 47.3±1.9, under the stairs ability was 43.4±2.1, the total score was 190.7±2.9. There were 2 cases in control group had fracture fragment displacement and 1 patient had nail withdraw. The results of AKS score:pain was 40.1±2.2, activity was 20.1±0.2, stability was 18.1±3.2, walking ability was 46.3±1.7, under the stairs ability was 40.2 ±1.3, the total score was 180.2±1.4. Therefore, the comparison of the above indicators, the results of the treatment group were better than those of the control group.</p><p><b>CONCLUSIONS</b>Rivet-assisted hollow screw fixation in the treatment of cruciate ligament avulsion fracture in the ending, has some advantages such as follows:accurate reduction, less postoperative complications and better postoperative knee function recovery, therefore it is an effective way to treat posterior cruciate ligament avulsion fracture.</p>

ABSTRACT

Objective:To investigate the regulation effect of endogenous nicotinamide phosphoribosyl transferase (Nampt) on the Vimentin expression of glomerular cells in high concentration glucose,and to clarify the mechanism of formation of diabetic kidney inflammation fibrosis.Methods:The C57/BL6 diabetic mice were selected and the kidney tissues were collected,and the wild C57/L86 mice were used as control group;the pathological section and tissue fluorescence staining were performed.The expression and location of endogenous Nampt and Vimentin in the glomerular cells were detected by immuno-focused technology.The HBZY-1 cells were randomly divided into 4 groups:low concentration of glucose (LG,0.56 mmol · L-1) control group,high concentration glucose (HG,200 mmol · L-1) group,HG +-FK866 group and HG+nicotinamide mononucleotide (NMN) group.In HG group,the cells were treated with FK866 (10 μmol · L-1) and NMN (1 mmol · L-1) for 24 h after cultured with HG for 5 d.The expression levels of Nampt,Vimentin,nuclear factor-kappa B p65 (NF-κBp65) and sirtuin type 1 (Sirt1) were detected by immunofluorescence and Western blotting methods.The expression levels of Nampt and Vimentin were detected by RT-PCR and Western blotting methods.Results:The shape and size of glomerulus had obvious atrophy of the mice in severe diabetic group compared with normal C57/BL6 mice group.The expression level of Vimentin in glomerular cells was increased with the increasing of endogenous Nampt (P<0.01).When the HBZY-1 cells were cultured in HG condition,the exprssion levels of Nampt,Vimentin and NF-kB p65 were obviously increased while the Sirt1 expression levels was significantly decreased compared with control group (P< 0.01).The expression levels of Nampt,Vimentin and NF-κB p65 in glomerular cells in HG+FK866 HG+ NMN groups were singnificartyly decreased compared with control group (P<0.01).Conclusion:The endogenous Nampt over-expression in glomerular cells can enhance the expression of Vimentin under high concentration of glucose stress through NF-κBp65 and Sirt1 signal pathway.
