Study on the sterilization effect of plasma jet and plasma activated water on Streptococcus mutans / 生物医学工程学杂志

To explore the effects of plasma jet (PJ) and plasma activated water (PAW) on the sterilization of Streptococcus mutans ( S. mutans) and compare the advantages and disadvantages of the two methods, so as to provide a basis for plasma treatment of dental caries and to enrich the treatment means of dental caries, an atmospheric pressure plasma excitation system was built, and the effects of PJ and PAW on the sterilization rate of S. mutans and the changes of temperature and pH during treatment were studied under different excitation voltage ( U e ) and different excitation time ( t e ). The results showed that in the PJ treatment, the difference in the survival rate of S. mutans between the treatment group and the control group was statistically significant ( P = 0.007, d=2.66) when U e = 7 kV and t e = 60 s, and complete sterilization was achieved at U e = 8 kV and t e = 120 s in the PJ treatment. In contrast, in the PAW treatment, the difference in the survival rate of S. mutans between the treatment group and the control group was statistically significant ( P = 0.029, d = 1.71) when U e = 7 kV and t e = 30 s, and complete sterilization was achieved with PAW treatment when U e = 9 kV and t e = 60 s. Results of the monitoring of temperature and pH showed that the maximum temperature rise during PJ and PAW treatment did not exceed 4.3 °C, while the pH value after PAW treatment would drop to a minimum of 3.02. In summary, the optimal sterilization parameters for PJ were U e =8 kV and 90 s < t e ≤ 120 s, while the optimal sterilization parameters for PAW were U e = 9 kV and 30 s< t e ≤ 60 s. Both treatment methods achieved non-thermal sterilization of S. mutans, where PJ required only a smaller U e to achieve complete sterilization, while at pH < 4.7, PAW only required a shorter t e to achieve complete sterilization, but its acidic environment could cause some chemical damage to the teeth. This study can provide some reference value for plasma treatment of dental caries.

Research advances in the mechanism of tumor microenvironment in pancreatic cancer and related targeted therapy / 临床肝胆病杂志

The tumor microenvironment of pancreatic carcinoma is a dense matrix environment with excessive fibrosis containing pancreatic stellate cells, cancer-associated fibroblasts, immune cells, and extracellular matrix, which not only creates an environment to promote the growth and invasion of tumors, but also makes them resistant to chemotherapy and other antitumor drugs. Intensive fibrosis reaction in the matrix and changes of tumors in immune environment are considered the main reasons for treatment failure in pancreatic cancer management. This article reviews the recent research advances in the tumor microenvironment of pancreatic cancer, summarizes its composition and pathogenesis and the targeted therapies for matrix and immune cells, and analyzes the importance of tumor microenvironment in the development and progression of pancreatic cancer and its impact on targeted therapy.

Objective:To assess the efficacy and safety of electroacupuncture (EA) at Houxi (SI 3) in treating acute lumbar sprain. Methods: Randomized controlled trials (RCTs) involving EA at Houxi (SI 3) for acute lumbar sprain were retrieved from PubMed (1966-2014), EMBASE (1980-2014), Cochrane Library (Issue 1, 2014), CQVIP Database (1989-2014), Wanfang Digital Journal (1998-2014), the Chinese Biological Medical Literature Database (CBM, 1978-2014), and China National Knowledge Internet (CNKI, 1979-2014). The collection of data also adopted hand-search of the relevant journals from the Library of Shanghai Jiao Tong University. All of the data were first evaluated and extracted by two reviewers independently with a specially designed form. Then, the available data were analyzed by the Cochrane Collaboration's RevMan 5.2.0 software. Results:A total of 6 trials involving 1 288 patients were eligible. Meta-analysis showed that the total effectiveness rate in the EA group was significantly different when compared with Nimesulide [RR=1.33; 95% CI (1.19 to 1.49)] and Mobic [RR=1.08; 95% CI (1.03 to 1.14)], but similar to that of acupuncture at Yaotongdian (EX-UE 7) [RR=71.09; 95% CI (1.00 to 1.19)] and Diclofenac Sodium [RR=1.08; (95% CI 0.96 to 1.21)]. The recovery rate in the EA group was significantly different when compared with Mobic [RR=1.67; (95% CI 1.45 to 1.92)] and Nimesulid [RR=1.37; (95% CI 1.15 to 1.62)], but similar to that of acupuncture at Yaotongdian [(RR=1.35; 95% CI 0.99 to 1.84)] and Diclofenac Sodium [(RR=1.19; 95% CI 0.88 to 1.61)]. Conclusion:Up to the search date, there are few high quality RCTs to evaluate the clinical efficacy of EA at Houxi (SI 3) for acute lumbar sprain, especially studies in English. Yet EA at Houxi (SI 3) still appeared to be an efficacious method for acute lumbar sprain, despite several inherent defects of the included studies. Further large scale trials are required to define the role of EA at Houxi (SI 3) in the treatment of this disease.

The influence of ferrule effect on post-restored restoration using extended finite element method / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the stress distributions and cracks initiation and propagation within the cementation of post and core restored teeth with various ferrule heights.</p><p><b>METHODS</b>Three-dimensional finite element (FE) models of post and core restored teeth with different ferrule heights (0, 1, 2, 3 mm) were created by using the data of a three-dimensional non-contact digital scanning.Vertical oblique forces of 350 N (45° to the long axis of the root) were applied on the lingual surface of the teeth (4 mm below the incisal edge). Both linear analysis and extended finite element methods (XFEM) were used to investigate stress distributions, especially those in the adhesive interfaces.</p><p><b>RESULTS</b>Linear analysis results showed that the stress distributions within the root were quite similar among the groups. However, obvious stress concentrations were detected on palatal glass ionomer cement layer in the groups with 0 mm and 1 mm ferrule. According to the XFEM results, cracks were firstly initiated within the glass ionomer cement layer, and then propagated towards the adhesive resin cement layer. The ultimate loads that induced the damage within glass ionomer cement layer and adhesive resin cement layer in 0 mm ferrule group (50.4 and 94.7 N) were less than those in 3 mm ferrule group (65.9 and 228.2 N).</p><p><b>CONCLUSIONS</b>Adhesive interface was the susceptible structure of post and core restored teeth.Increasing ferrule height can significantly reduced the stress concentration within the palatal adhesive interface.</p>

Effects of Guanxinkang on expressions of ATP-sensitive potassium channel subunits Kir6.1, Kir6.2, SUR2A and SUR2B in ischemic myocytes of rats / 中西医结合学报

Objective: To observe the effects of Guanxinkang injection, a compound traditional Chinese herbal medicine, on ATP-sensitive potassium (K(ATP)) channel subunits in ischemic myocardial cells of rats, and to explore the mechanism of Guanxinkang in protecting myocardial ischemic reperfusion injuries. Methods: Forty-eight Wistar rats were randomly divided into normal group, untreated group, glibenclamide group, pinacidil group, Guanxinkang group and Guanxinkang plus glibenclamide group. The ventricular myocytes were prepared from hearts of normal rats by enzymatic dissociation method. The ischemic ventricular myocytes underwent perfusion with normal Tyrode solution for 10 min, then stopping perfusion 30 min, and followed by 45 min of reperfusion. The glibenclamide, pinacidil and Guanxinkang were added into ventricular myocytes solution directly. Then the solutions were placed at 4 degrees centigrade. After 24-hour freezing at -80 degrees centigrade, mRNA and protein expressions of KATP subunits Kir6.1, Kir6.2, SUR2A and SUR2B were measured by real-time quantitative polymerase chain reaction and Western blotting respectively. Results: In normal rat myocardial cells, there were SUR2A, Kir6.1, and Kir6.2 protein and gene expressions but no expression of SUR2B protein. In the untreated group, all subunit mRNA and protein expressions of KATP increased to some extent as compared with the normal group. Pinacidil, a potassium channel opener, significantly increased mRNA and protein expressions of KATP subunits, while the blocker glibenclamide had a reverse effect. Meanwhile, Guanxinkang injection significantly increased mRNA and protein expressions of K(ATP) subunits but with no significant difference as compared with pinacidil. Conclusion: Guanxinkang injection can obviously enhance the open of KATP channel and thus play a role in cardiovascular protection.

Modulation of Jianjining Recipe on differential protein expression in rats with experimental autoimmune myasthenia gravis / 中西医结合学报

OBJECTIVE: To study the modulation of Jianjining Recipe (JJNR), a traditional Chinese compound herbal medicine for invigorating spleen and kidney on differential protein expression in spleen of rats with experimental autoimmune myasthenia gravis (EAMG). METHODS: EAMG rats were randomly divided into four groups: untreated group, JJNR-treated group, Qiangji Jianli capsule (QJJLC, a traditional Chinese compound herbal medicine)-treated group and prednisolone acetate (PA)-treated group. After therapeutic intervention with the above drugs for four consecutive weeks, the level of differential protein expression was analyzed by two-dimensional electrophoresis and matrix assisted laser desorption/ionization time-of-flight mass spectrometry. RESULTS: Twelve differential proteins were identified by comparing EAMG rats and normal rats. The levels of allograft inflammatory factor-1, peroxiredoxin I and actin-related protein 2/3 complex subunit 5 were significantly regulated by JJNR (P<0.01). These proteins were closely associated with immune response and cell movement. CONCLUSION: The results suggest that there are differential protein expressions between EAMG rats and normal rats. Furthermore, as a Chinese medicine prescription with effect of invigorating spleen and kidney, JJNR can effectively regulate the levels of some EAMG-related protein expression.
