ObjectiveTo investigate the molecular mechanism by which Si Junzitang in intervening in the development of hepatocellular carcinoma （HCC） by regulating the O-linked β-N-acetylglucosamine modification （O-GlcNAcylation） of nuclear factor kappa-B （NF-κB） p65 in the paracancerous tissues. MethodThe orthotopic liver cancer mouse model was established. Twenty-four C57BL/6 mice were randomly divided into four groups： Normal group， model group， Si Junzitang low-dose group （10 g·kg^-1）， and Si Junzitang high-dose group （25 g·kg^-1）， with 6 mice in each group. The O-GlcNAcylation level and phosphorylation modification level of p65 in the paracancerous tissues were detected using Western blot. The O-GlcNAcylation of p65 was assessed using immunoprecipitation （IP）. The mRNA expression of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， transforming growth factor-β₁ （TGF-β₁）， vascular endothelial growth factor A （VEGFA）， matrix metalloproteinase-2 （MMP-2）， matrix metalloproteinase-9 （MMP-9） in the paracancerous tissues was detected using real-time quantitative polymerase chain reaction （Real-time PCR）. The tumor number， liver weight， locomotor activity， grip strength， and Qi status of the mice were observed and analyzed. ResultCompared with the normal group， the model group showed a significant decrease in O-GlcNAcylation in the paracancerous tissues （P<0.01）， a significant decrease in p65 O-GlcNAcylation （P<0.01）， a significant increase in p65 phosphorylation （P<0.01）， significantly elevated mRNA levels of cytokines IL-6， TNF-α， TGF-β₁， VEGFA， MMP-2， and MMP-9 （P<0.01）， significantly increased liver weight （P<0.01）， significantly declined grip strength， number of grid crossings， and number of vertical stand-ups （P<0.01）， and significantly dwindled Qi status （P<0.01）. Compared with model group， the Si Junzitang low-dose and high-dose groups showed significantly increased levels of O-GlcNAcylation in the paracancerous tissues （P<0.05， P<0.01）， significantly upregulated p65 O-GlcNAcylation levels （P<0.05， P<0.01）， and significantly decreased p65 phosphorylation levels （P<0.01）. In the Si Junzitang low-dose group， the mRNA levels of IL-6， TGF-β₁， and VEGFA significantly decreased （P<0.05， P<0.01）. In the Si Junzitang high-dose group， the mRNA levels of IL-6， TNF-α， TGF-β₁， VEGFA， MMP-2， and MMP-9 significantly decreased （P<0.01）， the number of tumors larger than 3 mm in diameter significantly decreased （P<0.01）， and liver weight significantly decreased （P<0.05）. Additionally， grip strength， number of grid crossings， and number of vertical stand-ups significantly increased （P<0.05， P<0.01）， along with a significant increase in qi status （P<0.01）. ConclusionSi Junzitang can inhibit the progression of orthotopic HCC in mice， which may be achieved by increasing the O-GlcNAcylation level in the paracancerous tissues， enhancing the O-GlcNAcylation of p65， inhibiting the phosphorylation modification of p65， and ultimately suppressing the expression of downstream IL-6， TNF-α， TGF-β₁， VEGFA， MMP-2， and MMP-9.

Objective:To explore the therapeutic mechanism of electroacupuncture(EA)in treating Parkinson disease(PD)using Tandem mass tag(TMT)quantitative proteomics technology. Methods:Forty-eight PD patients were randomly divided into a control group and an observation group,with 24 patients in each group.The control group received routine drug treatment,while the observation group received EA in addition to the routine drug treatment.EA was administered for 30 min per session,3 times a week,for a total of 12 weeks.Nine patients from each group were randomly selected to provide peripheral blood serum samples before and after treatment for TMT quantitative proteomics analysis.Differentially expressed proteins between the two groups were compared,and bioinformatics analysis was performed.The screened differentially expressed proteins were validated using enzyme-linked immunosorbent assay(ELISA). Results:In the observation group,scores on the unified Parkinson disease rating scale(UPDRS),UPDRS Ⅱ,and UPDRS Ⅲ were significantly reduced after treatment(P<0.05).In the control group,these scores tended to increase,but the changes were not statistically significant(P>0.05).After treatment,the UPDRS and UPDRS Ⅲ scores in the observation group were significantly lower than those in the control group(P<0.05).The observation group showed 62 differentially expressed proteins,while the control group had 36.Compared to the control group,the observation group had 142 differentially expressed proteins.These proteins were primarily involved in the cyclic adenosine monophosphate(cAMP)signaling pathway,T helper(Th)1 and Th2 cell differentiation,ATP-binding cassette transporter,vascular endothelial growth factor signaling pathway,and high-affinity immunoglobulin E receptor(FcεRI)signaling pathway.ELISA verification indicated that after EA treatment,the levels of α-Synuclein(αSyn)and heat shock protein beta 1(HSPB1)in the observation group were significantly lower than those in the control group(P<0.05),while the regulator of G-protein signaling 10(RGS10)level was significantly higher(P<0.05). Conclusion:EA,combined with routine drug therapy,can significantly improve clinical symptoms of PD,potentially through the regulation of the cAMP signaling pathway and the contents of differentially expressed proteins of αSyn,HSPB1,and RGS10.

Objective:To systematically assess the efficacy and safety of acupuncture therapy for essential hypertension.Methods:A computerized literature search of the Chinese National Knowledge Infrastructure(CNKI),Chongqing VIP Database(CQVIP),Wanfang Academic Journal Full-text Database(Wanfang),China Biology Medicine Disc(CBM),PubMed,Excerpta Medica Database(EMBASE),and Cochrane Library was conducted to retrieve randomized controlled clinical trials on acupuncture as the main intervention for the treatment of essential hypertension published from the inception of the database to 30 January 2021.The risk-of-bias assessment was carried out for each included study according to the Cochrane Handbook.Data analysis was performed using Review Manager 5.4.1 and Stata 15.0.Results:After the screening,46 randomized controlled trials involving a total of 3 859 subjects were included.Primary outcomes included changes in the diastolic blood pressure after intervention[eight studies showed that the acupuncture plus antihypertensive drug group was better than the antihypertensive drug monotherapy group[mean difference(MD)=1.45,95%confidence interval(CI)(0.48,2.43),P=0.004,fixed effects model;I2=39%]and changes in the systolic blood pressure after intervention{11 studies showed that the acupuncture plus antihypertensive drug group was better than the antihypertensive drug monotherapy group[MD=8.60,95%CI(7.12,10.07),P<0.00001,fixed effects model;I2=26%]}.The secondary outcome was antihypertensive efficacy,12 studies of acupuncture monotherapy group[risk ratio(RR)=1.20,95%CI(1.12,1.28),P<0.00001,fixed effects model;I2=36%]and 15 studies of acupuncture combined with antihypertensive drug group[RR=1.27,95%CI(1.20,1.34),P<0.00001,fixed effects model;I2=6%]showed better results than the antihypertensive drug monotherapy group in antihypertensive efficacy.In terms of the adverse events,four studies showed that the acupuncture monotherapy group had fewer adverse events than the antihypertensive drug monotherapy group[RR=0.10,95%CI(0.04,0.25),P<0.00001,fixed effects model;I2=0%].Conclusion:Acupuncture combined with antihypertensive drugs is superior to antihypertensive drugs alone in reducing blood pressure,and acupuncture therapy is effective and safe for the treatment of essential hypertension with fewer side effects.However,there is still a lack of high-quality multicenter randomized double-blinded controlled trials in this field.Rigorous large-sample clinical trials are needed to validate these findings.

Diabetes mellitus is one of the most common complications after liver transplantation. The survival rate of recipients after liver transplantation with diabetes mellitus and the long-term survival rate of grafts are significantly lower than those of their counterparts without diabetes mellitus. In recent years, diabetes mellitus after liver transplantation has attracted widespread attention along with the rapid development of liver transplantation in China. Although post-transplantation diabetes mellitus (PTDM) has been extensively investigated in the past two decades, multiple problems remain to be further resolved. The study was designed to review the latest research progress upon diabetes mellitus after liver transplantation, covering the definition and diagnostic criteria of PTDM, risk factors, prevention and treatment of diabetes mellitus after liver transplantation, aiming to deepen the understanding of diabetes mellitus following liver transplantation, deliver effective prevention and management, improve the long-term survival rate and enhance the quality of life of the recipients.

Objective To evaluate the clinical experience of extracorporeal membrane oxygenation (ECMO) treatment on two cases of infection with the critical Corona Virus Disease 2019 (COVID-19) complicated by fulminant myocarditis (FM) . Methods This study selects two COVID-19 cases comorbid with fulminant myocarditis and had been treated with ECMO in Shenzhen Third People's Hospital from January 2020 to February 2020. We compare the index of inflammation, immunization, D-dimer and lactic acid before and after ECMO treatment in 24 and 96 hours, cardiopulmonary function before and after ECMO treatment in 24, 48, 72, 96 hours,. We also analyze the complications and clinical outcomes of the two cases during the ECMO treatment. Results Both patients were elderly obese men with chronic cardiopulmonary disease. Comparing the laboratory test results and imaging data of the two patients, the acute lung injury score, oxygenation index, albumin level, hypersensitive C-reactive protein, lactate and lactate dehydrogenase levels in 2 patients after ECMO treatment were improved as compared with those before ECMO treatment. Finally, case 1 died of multiple organ failure and his cardiac function continued to deteriorate, while, case 2 successfully withdrew and his cardiac function gradually improved. Conclusions For critical COVID-19 patients with fulminant myocarditis, ECMO treatment can improve pulmonary function in the short term, provide valuable time for rescuing COVID-19 patients with fulminant myocarditis.

The present investigation reports the chemical composition of the Rhus typhina L. stem identified via mass spectrometry and NMR as gallic acid, 1-O-galloyl-β-D-glucose, tryptophan, scopolin, methyl gallate, fustin, quercetin, rutin, and 1,2,3,4,6-penta-O-galloyl-β-D-glucose. The antioxidant properties and the chemical composition contents of the R. typhina L. stem grown in different regions in China were de-termined. To determine the antioxidant activity, a total phenolic content analysis, 2, 2-diphenyl-1-pi-crylhydrazyl radical scavenging activity assay, ferric reducing antioxidant power assay, andβ-carotene linoleic acid model system were conducted. The results showed that the Rhus typhina L. stem possessed high antioxidant capacities due to its high phenolic content. The contents of the nine isolated compounds were determined by UPLC-ESI-MS/MS. The calibration curves of the nine isolated compounds were linear within the concentration range and the average recoveries were high. The result showed that 1-O-galloyl-β-D-glucose, gallic acid, methyl gallate, and 1,2,3,4,6-penta-O-galloyl-β-D-glucose could be the compounds mainly responsible for the antioxidant capacity of the R. typhina L. stem. This reveals that the R. typhina L. stem is a good source of antioxidants.

In recent years, with the widespread clinical application of moxibustion, the clinical trials on moxibustion research are also increasing. However, the establishment of negative control of moxibustion, also called as mimicking moxibustion, has become a major challenge in the randomized controlled trials (RCTs) . In this review, we summarized the establishment methods of mimicking moxibustion in RCTs at home and abroad, and evaluated and elaborated the design and application methods of mimicking moxibustion models from thermal effect, light radiation effect and smoke effect that generated by moxibustion, in order to provide insights for the establishment of an ideal and feasible mimicking moxibustion model in future RCTs of moxibustion.

BACKGROUND:Stem cel transplantation is increasingly hoped to promote osteoblast differentiation and inhibit osteoclast proliferation in the treatment of osteoporosis.
OBJECTIVE: To study the therapeutic effect of exogenous adipose-derived stem cel (ADSC) transplantation on osteoporosis in ovariectomized rats.
METHODS:Thirty Sprague-Dawley female rats were equivalently randomized into sham, model, ADSC transplantation groups. Rats in al groups except the sham group underwent bilateral ovariectomy to make osteoporosis models. Surrounding adipose tissues instead of the ovary were removed in the sham group. After modeling, rats were given 2×106ADSCs at passage 4via the tail vein in the transplantation group and the same volume of normal saline in the model group, once a week. After 6 weeks, levels of serum calcium, phosphorus, and alkaline phosphatase as wel as bone mineral density and histomorphometry indicators were detected in rats.
RESULTS AND CONCLUSION:Compared with the sham group, the trabecular bone volume fraction was significantly decreased in the model group (P < 0.01), but remarkably increased after ADSC transplantation (P < 0.05). After modeling, the bone trabecular absorption surface percentage and rate of bone trabecular formation were elevated significantly (P < 0.05 orP < 0.01), while these increases were improved by ADSC transplantation (P < 0.05). Additionaly, the levels of serum calcium and alkaline phosphatase and bone mineral density were significantly decreased after modeling, but were increased after ADSC transplantation. In contrast, the serum level of phosphorus was significantly increased in the model group (P < 0.05) but decreased markedly in the ADSC transplantation group (P < 0.05). To conclude, ADSC transplantation can reduce the loss of bone mass in osteoporosis rats by ovariectomy.

OBJECTIVETo analyze virulence genes and molecular characteristics of Vibrio parahaemolyticus isolated from sporadic cases with diarrhea in tow sentinel hospitals of Shanghai, 2010-2012.

METHODSA total of 2 729 stool samples were collected from two surveillance sentinel hospitals in Shanghai 2010-2012. Vibrio parahaemolyticus strains were isolated and identified from diarrhea out patients using TCBS agar plates and biochemical reactions. Thermostable direct hemolysingene (tdh), thermostable-related hemolysin gene (trh), hemolysin gene (tlh) were detected by multiplex PCR method. Isolates were analyzed by PFGE and MLST. The PFGE profiles were analyzed using BioNumerics software.

RESULTSA total of 30 clinical Vibrio parahaemolyticus strains isolated from 2 729 stool samples. The anually Vibrio parahaemolyticus isolation rate during 2010 to 2012 were 1.1%(11/973), 1.0%(11/1 120) and 1.3%(8/636) respectively. The PCR positive rates of virulence genes tlh, tdh and trh were 100%, 97% and 0 respectively. The Vibrio parahaemolyticus strains were divided into 13 PFGE types (P1-P13)and 3 ST types (ST-189, ST-799, ST-3). Among 13 PFGE types, P4 was the main PFGE type, accounting for 30%(9/30). P9, P10 were accounting for 12% (4/30) respectively, P1, P2, P12, P13 were accounting for 7%(2/30) respectively, the others types were 3%(1/30) respectively. MLST analysis results showed there are three ST types, ST3 was 84%(25/30), ST189 and ST799 were accounting for 13% (4/30) and 3% (1/30) respectively.

CONCLUSIONThe infection rate of Vibrio parahaemolyticus was not very high from 2010-2012 in Shanghai, all strains were positive for tlh and negative for trh. ST3 was the major type of Vibrio parahaemolyticus.
