摘要
This study systematically searched and sorted out randomized controlled trial(RCT) of acupuncture-moxibustion treatment for non-specific low back pain by scoping review, so as to demonstrate the current state of the research evidence and provide a reference point for future clinical research and healthcare decision-making. Eight commonly used Chinese and English databases were searched, and the search time was from the establishment of the databases to July 7, 2023, so as to analyze the characteristics of the current status of the current research through visualization methods. A total of 50 studies were included, including 23 studies in Chinese and 27 studies in English. The overall number of studies showed an increasing trend. The percentage of studies published in Chinese non-core journals was 42.0%. The disease subtypes of interest were mainly chronic non-specific low back pain, accounting for 68.0% of the studies. The sample sizes of the studies were mainly concentrated in the range of 50-100 cases. A total of 15 types of interventions were categorized, with acupuncture interventions being the most studied. Duration of treatment did not exceed one month in 80.0% of the studies. Only 8.0% of the studies used minimal clinical important difference(MCID) as a basis for judgment. The follow-up period was set within 3 months in 28.0% of the studies, and 82.0% of the studies concluded that acupuncture-moxibustion was effective in the treatment of non-specific lower back pain. Adverse events were reported in 20.0% of the studies. The risk of bias in the included studies was dominated by low risk of bias and uncertain risk of bias, with fewer studies focusing on high risks of bias. In most of the studies, acupuncture-moxibustion was significantly more effective than the control group. The research on acupuncture-moxibustion treatment for non-specific low back pain is developing rapidly, but there are still insufficient studies on psychological state, safety, and other indicators, and there are still some studies with uncertain risks of bias, which is not conducive to the generalization and application of the findings. Therefore, future studies should improve and refine these shortcomings.

According to the systematic review of text and opinion(SrTO) developed by the Joanna Briggs Institute(JBI), this study integrated the evidence of the medical cases, papers, medical experience, and other related research of famous experts and schools on the treatment of chronic renal failure in the field of traditional Chinese medicine(TCM) nephropathy, analyzed the academic characteristics and influencing factors from the aspects of the principle, method, recipe, and medicines, and explored the internal logic and law of inheritance and innovation in TCM nephropathy. A total of 36 famous TCM experts and 4 schools were included. The work areas are concentrated in North and South China. 94.0% of the famous TCM experts have experienced master-disciple teaching. 27.8% have studied TCM through family succession. 38.9% have been taught by multiple famous teachers. And 5.6% have not experienced master-disciple teaching. In terms of principle, method, recipe, and medicines, many innovations have been made, with 30.6% of famous TCM experts proposing new theories, 11.1% advocating staged treatment of chronic renal failure, and 47.2% summarizing the treatment methods. The formation of the academic thoughts of contemporary famous TCM experts and schools on the treatment of chronic renal failure is closely related to the learning mode, era, and work area. Contemporary famous TCM experts and schools have the academic characteristics of combining classical and clinical theories and paying more attention to TCM with western medicine supplemented. The field of TCM nephropathy has the characteristics of simultaneous inheritance and innovation. On the basis of inheriting the classical theories of TCM, it absorbs modern medical theories, combines clinical diagnosis with the syndrome and treatment law of contemporary diseases, and makes innovations in principle, method, recipe, and medicines, which has significant clinical efficacy in the treatment of chronic renal failure.

The rheological properties of six compound gels that consists of kappa carrageenan (KC) and another excipient such as konjac gum were explored through comparison of their viscosity measured by the rotation method. The gel fluid type was dependent on the rheological curve fitted by the power-law equation. The effect of concentration on the viscosity of different compound gels was investigated by establishing the linear equation between their viscosity and concentration, the slope of which was used to determine the relation between viscosity and concentration of different compound gels. The viscous flow activation energy (Eη) was calculated by the Arrhenius equation, which was able to investigate the effect of temperature on their viscosity. The interaction between monomer and compound gels was also studied by measuring their viscosity. The results showed that six compound gels were pseudoplastic fluid. Among all compound gels, the KC-xanthan gum (KC-XG) solution exhibited the most obvious shear thinning, the strongest pseudoplasticity, while the smallest Eη, resulting in the best thermal stability of viscosity. Furthermore, the concentration of KC-sodium hyaluronate (KC-HA-Na) solution affected its viscosity significantly. The viscosity of six compound gels was greater than the summation of the two kinds of monomer gels, which suggests that there is a synergistic-viscosity interaction between KC and another excipient.

Objective To establish four finite element models for repairing root canals of the maxillary central incisors, study the influences from different post and core materials as well as root canal rehabilitations on stress distributions of the maxillary central incisors, so as to provide theoretical references for clinical application. Methods Four finite element models of repairing system were established by CBCT scanning, Mimics software, Rapidform.xor3, Solidworks and Ansys Workbench software. The occlusal loads were simulated and Von Mises stresses on the roots were calculated. Results Four precise 3D finite element models for repairing maxillary central incisors were established, including dentin, all ceramic crow, coping crown, post and core, gutta percha point, periodontal ligament, glue and alveolar bone. The analysis found out that different post and core materials as well as glues had different influences on Von Mises stress of the dentins as the greater elastic modulus of the post was, the smaller Von Mises stresses of the dentin would be. The Von Mises stress on the post and core made of cobalt-chromium alloy was 23.15 MPa, which was the smallest. Conclusions Stress distributions on repairing systems of the maxillary central incisors with different post and core materials can be predicted by establishing such different finite element models and provides a basis for the clinical application of maxillary central incisors repair systems.

Objective To investigate the oncolytic effect of E1B mutant adenovirus (d11520) on human malignant gliomas. Methods Ad-βgal vector was used to investigate the infectibility of dl1520.U251,Hep3B (positive control) and T24 (negative control) cell lines were infected with dl1520respectively at 50,5,0.5,0.005 and 0 pfu of multiplicity of infection (MOI).The replication efficiency of d11520 in host cells was assessed by plaque assay.The cytopathic effect (CPE) was assessed by crystal violet staining in a panel of tumor cells. Results Crystal violet staining showed the Hep3B cell line was the most sensitive to dl1520 and had the fastest CPE,followed by the U251 cell line,while the T24cell line had no CEP.The replication and infection rates ofdl1520 in the U251 cell line were lower than in the Hep3B cell line but significantly higher than in the T24 cell line (P<0.05). Conclusion The E1B mutant adenovirus (dl1520) has a significant oncolytic effect on human malignant gliomas.
摘要
<p><b>BACKGROUND</b>A liver support therapy, named molecular adsorbents recirculating system (MARS), has been used for more than 700 liver failure patients in China. We made here a summary to evaluate the effects of MARS treatment in different applications with emphasis on hepatitis B virus (HBV) based liver failure.</p><p><b>METHODS</b>This report analyzed data of 252 patients (mean age (44.9+/- 12.7) years) in three groups: acute severe hepatitis (ASH), subacute severe hepatitis (SSH) and chronic severe hepatitis (CSH). The largest group was CSH (156 patients, 61.9%), and 188 patients (74.6%, 188/252) were infected with HBV.</p><p><b>RESULTS</b>MARS treatments were associated with significant reduction of albumin bound toxins and water-soluble toxins. Most of the patients showed a positive response with a significant improvement of multiple organ function substantiated by a significant increase in prothrombin time activity (PTA) and median arterial pressure (MAP). There was a decrease in hepatic encephalopathy (HE) grade and Child-Turcotte-Pugh (CTP) scale. Thirty-nine of 188 HBV patients (20.7%) dropped out of the commendatory consecutive therapy ending with lower survival of 43.6% while the rest of the 149 patients had a survival rate of 62.4%. Survival within the ASH and SSH groups were 81.2% and 75.0%, respectively. In the CSH group, end stage patients were predominant (65/151, 43%), whereas the early and middle stage patients had a better prognosis: early stage survival, including orthotopic liver transplantation (OLT) survival of 91.7%, middle stage survival of 75%, end stage survival of 33.8%.</p><p><b>CONCLUSIONS</b>MARS continues to be the most favorable extracorporeal treatment for liver support therapy in China for a wide range of conditions, including the majority of hepatitis B related liver failure conditions. The appropriate application of MARS for the right indications and stage of hepatic failure, as well as the fulfillment of prescribed treatments, will lead to the optimal therapeutic result.</p>

<p><b>OBJECTIVE</b>To summarize the clinical changing characters of the clinical markers after interferon treatment in chronic hepatitis B (CHB) and make out practical indexes to predict the effect.</p><p><b>METHODS</b>150 CHB patients were randomly divided into two groups: therapeutic group (90) and control group (60) in the prospective controlled trial. The levels of endogenous interferon before treatment, interferon antibody at the end of the second month and fourth month after treatment, alanine aminotransferase (ALT) and HBV DNA in the serum were detected. Then the data was analysed to find out indexes for predicting the effect.</p><p><b>RESULTS</b>(1) The clearance rate of HBeAg had no significant difference in age except for 20 - 30 and 30 - 40 (t > 2.331 2, P < 0.01). (2) It was more effective if ALT level was higher than 400 U/L before treatment and it decreased more than 50% two months after treatment. (3) The patients whose HBV DNA was negative (dot hybridization) or less than 10(6) copies/ml before treatment had higher rate of HBeAg clearance. (4) There was no effect on patients whose interferon antibody turned positive at the end of the second month. (5)A predictive method of comprehensive factors was made out, whose sensitivity, specificity, and accuracy were 80%, 100% and 90%, respectively.</p><p><b>CONCLUSION</b>The clinical characters of these Chinese patients are different from those of the westerners and the effects of interferon have close relation to the levels of ALT, HBV DNA and interferon antibody.</p>
