Da Chengqitang in Treatment of Sepsis： A Review / 中国实验方剂学杂志

Sepsis is a systemic inflammatory syndrome induced by infection and other factors， with the number of patients worldwide exceeding 10 million each year. The pathophysiological mechanism is of this disease complex. Sepsis is often accompanied by endotoxin translocation， gastrointestinal dysfunction， inflammatory cytokine activation， immune dysregulation， coagulation disorder， multiple organ function impairment and many other body imbalances， as well as systemic inflammation， apoptosis， oxidative stress injury and other cell damage mechanisms. This disease causes a heavy medical burden due to the difficult diagnosis and treatment and the poor prognosis. Great progress has been achieved in the diagnosis and treatment of sepsis with traditional Chinese medicine （TCM） and western medicine. The value of western medicine in the diagnosis and treatment of sepsis is limited due to antibiotic resistance， hormone abuse， and high medical costs. Sepsis is classified as a warm disease or typhoid fever in TCM. Da Chengqitang is a classical formula in the Treatise on Typhoid Fever to deal with the excess syndrome of Yang brightness Fu-organ. Modern medicine has proved that Da Chengqitang has the effect of inhibiting oxidative stress， reducing inflammation， and delaying apoptosis by improving gastrointestinal dynamics and regulating intestinal microecology. On the basis of the previous theoretical basis and the rich experience in the medication， medical practitioners have proposed a new therapeutic concept of using Da Chengqitang in combination with western drugs from a holistic view involving both bacteria and toxicity for treating both the symptoms and the root cause， which has a wide range of application. The article reviews the classical research and latest findings of Da Chengqitang in the treatment of sepsis， with a view to clarifying the mechanism and advantages of this formula in the adjuvant treatment of sepsis， exploring its potential efficacy， and providing timely， adequate， and scientific theoretical support for the promotion of this formula in the clinical practice.

Application of sliding osteotomy in total knee arthroplasty for patients with extra-articular femoral deformity / 中国骨伤

OBJECTIVE@#In order to observe the clinical effects of sliding osteotomy for patients with severe knee osteoarthritis and varus knee due to complex femoral extra-articular deformity to achieve the medial and lateral soft tissue balancing during total knee arthroplasty.@*METHODS@#From June 2014 to January 2018, a total of 22 patients with severe knee osteoarthritis and complex extra-articular malformation of femurs were treated with total knee arthroplasty. There were 5 males and 17 females in this group, aged 48 to 76 years old, with an average age of (61.3±13.8) years old. All the patients had varus deformities caused by extra-articular deformities of femur. Hip-knee-ankle(HKA) angle was(158.8±9.7) ° before operation, and the average Knee Society Score (KSS) clinical score was 32.6±6.1;KSS function score was 35.8 ±9.6;the average Hospital for Special Surgical (HSS) score was 39.7±4.6;the average range of motion before operation was (80.6±10.7) °. The mechanical alignment method was used in joint replacement. The flexion space was balanced first. The coronal plane vertical sliding osteotomy was performed on the medial femoral condyle for the imbalance of coronal plane. The sliding distance of the osteotomy block was determined by straightening the gap between the inner and outer sides of the space until the space was balanced. After the separated segments were fixed with several screws, the prosthesis was installed as usual.@*RESULTS@#The wounds of all patients healed in the first stage, and no wound complications occurred. All the 22 patients were followed up, and the duration ranged from 18 months to 3 years with an average of (28.2±10.1) months. X-ray showed that the fracture line disappeared for 2 to 5(3.5±1.5) months without nonunion. HKA angle measured at the latest follow up was (178.8±0.7) °, which wassignificantly different from that before operation. The HSS score was 91.3 ±6.0;KSS clinical score 93.7±3.5;KSS functional score 81.2±6.5;and the average range of motion of knee joint was(121.7±11.6) °, which was statistically significant compared with that before operation.@*CONCLUSION@#For severe knee osteoarthritis patients with complex femoral extra-articular deformity, sliding osteotomy is performed. For severe varus deformity, downward sliding the medial femoral condyle is performed. The operation is relatively simple and the damage is small. It is easy to achieve the balance of internal and external soft tissue in flexion extension space. The short-term clinical effect is satisfactory.

Magnetic resonanceT1ρversus T2 mapping for evaluating ischemic lumbar intervertebral disc degeneration in a rabbit model / 中国组织工程研究

BACKGROUND: MRI T1ρ and T2 mapping have been applied to study lumbar intervertebral disc degeneration in human and rhesus monkey, showing that they can be used for evaluating the early degeneration, but their application in New Zealand rabbit lumbar intervertebral disc degeneration is never reported.OBJECTIVE: To compare the relaxation time values of T1ρ and T2 mapping at different time points in a New Zealand rabbit model of ischemic lumbar intervertebral disc degeneration, and to compare the sensitivity for degeneration.METHODS: Fifteen New Zealand rabbits were randomly divided into three groups, and one of intervertebral discs at L4-5,L5-6 and L6-7 was designed for ischemic lumbar intervertebral disc degenerative model and the other two discs for controls. All the rabbits underwent T1ρ and T2 mapping preoperatively, 1, 3 or 6 months postoperatively to analyze the changes in the relaxation time at different time points.RESULTS AND CONCLUSION: (1) In the modeling group, the T2 mapping relaxation time of nucleus pulposus was (118.53±20.51) ms and (85.42±11.65) ms at 3 and 6 months after modeling, respectively, which showed significant difference when compared with preoperatively (146.21±16.93) ms (P < 0.05); but the time showed no significant difference compared with 1 month after modeling (P > 0.05). (2)T1ρ relaxation time of nucleus pulposus was (64.75±14.63) ms at 6 months after modeling, which showed significant difference when compared with preoperatively (87.88±8.87) ms (P < 0.05); but the time showed no significant difference compared with 1 and 3 months after modeling (P > 0.05). (3) In the control group, there was no significant difference in the T1ρ or T2 mapping relaxation time of nucleus pulposus before operation with 1, 3 or 6 months after operation (P > 0.05). The Pfirrmann grade of lumbar intervertebral disc was changed to Pfirrmann grades II-III at 6 months after modeling. (4) These results suggest that MR T1ρ and T2 mapping both are quantitative tools for evaluating the progress of ischemic lumbar intervertebral disc degeneration in New Zealand rabbits, especially the T2 mapping MRI may be more sensitive to early degenerative changes.

Icariside Ⅱ improves left ventricular cardiomyocyte apoptosis in spontaneously hypertensive rats / 中国药理学通报

Aim To observe the effect of icariside Ⅱ(ICS Ⅱ)on cardiomyocyte apoptosis in spontaneously hypertensive rats (SHR)and to explore its possible mechanism. Methods Thirty male 13-week-old SHRs were randomly divided into model group,ICS Ⅱ low, medium,high and positive drug group (n = 6),ho-mologous male Wistar-Kyoto rats as control group (n =6). After a week of adaptive feeding,ICS Ⅱ low,me-dium and high dose groups were given ICS Ⅱ 4,8,16 mg · kg - 1 (ig,qd),and the positive drug group was given losartan 20 mg·kg - 1 . At the same time,the WKY and SHR group were given equal volume double distilled water. After 12 weeks of administration,the blood pressure was measured in rats. Then,the rats were sacrificed and the left ventricles were separated in order to calculate the left ventricular mass index. HE staining was used to observe the pathological changes of the left ventricle,and the apoptosis of the left ventricu-lar myocardium was detected by TUNEL staining. The expressions of Bcl-2 and Bax mRNA in left ventricle were detected by real time RT-PCR,and Bcl-2,Bax and cleaved-caspase-3 protein expressions were detec-ted by Western blot. Results Compared with WKY group,the blood pressure and left ventricular mass in-dex increased in SHR group (P < 0. 05),and the my-ocardial cell arrangement was disordered and the cell hypertrophy and apoptosis were obvious,accompanied by rupture of filament ;the level of Bax mRNA was up-regulated (P < 0. 05),and Bcl-2 mRNA was down-regulated (P < 0. 05 );the expressions of Bax and cleaved-caspase-3 protein were up-regulated (P <0. 05),and the level of Bcl-2 protein was down-regu-lated (P < 0. 05 ),and the ratio of Bax / Bcl-2 in-creased (P < 0. 05). Compared with SHR group,the blood pressure and left ventricular mass index de-creased in ICS Ⅱ middle,high group and the positive drug group (P < 0. 05);moreover,the arrangement of myocardial cells became more orderly,the cell hyper-trophy and the apoptosis of myocardial cells were im-proved;the level of Bax mRNA was down-regulated and Bcl-2 mRNA was up-regulated (P < 0. 05);the expression of Bax and cleaved-caspase3 protein were down-regulated and the level of Bcl-2 protein was up-regulated (P < 0. 05 );the ratio of Bax / Bcl-2 de-creased (P < 0. 05). Conclusions ICS Ⅱ can im-prove the left ventricular cardiomyocytes apoptosis in SHR,and its mechanism is related to the decrease of blood pressure and the inhibition of mitochondrial ap-optosis pathway.

Determination of Seven Urinary Metabolites of Organophosphate Esters Using Liquid Chromatography-Tandem Mass Spectrometry / 分析化学

A simple method was developed for simultaneous determination of seven urinary metabolites of organophosphate esters by liquid chromatography-tandem mass spectrometry (LC-MS / MS). Based on different physical and chemical properties of these OPs metabolites, the solid phase extraction cartridges and the washing and eluting solvents were optimized in details. Furthermore, the mobile phase and mass spectrometric parameters were also investigated. The results showed that Oasis WAX cartridge was the best SPE column in this study, and 2 mL of NH3 ·H2 O (5% ) in methanol and 2 mL of methanol were chosen as the eluting solvents. The recoveries of six analytes were ranged from 60. 5% to 104. 0% , whereas DEP ranged from 17. 8% to 36. 2% . Seven analytes could be baseline separated from each other under the optimized chromatographic conditions. The limits of detection and quantification of seven analytes ranged from 0. 005 to 0. 2 μg / L and 0. 02 to 0. 5 μg / L, respectively. The standard deviations of response repeatability for intra-day and inter-day period were lower than 15. 4% . This method was finally applied to determination of metabolites of OPs from 10 urines from general population in Guangzhou city. The concentrations of total OPs metabolites in urine samples ranged from 0. 5 to 6. 7 μg / L.

OBJECTIVE: To further investigate the effect of platelet lysate and domestic porous tantalum scaffold constructs on the proliferation of MG63 cells and expression of integrin β1 (ITGβ1)/Vinculin/F-actin signaling pathway based on our previous findings. METHODS: MG3 cells were cultured and inoculated onto domestic porous tantalum scaffolds with the addition of 3%, 5%, 7% and 10% platelet lysates. Then, 7% as the best volume fraction of platelet lysate was screened by cell counting kit-8 method. There were four experimental groups including blank group (normally cultured MG63 cells), platelet lysate group (MG63 cells were cultured in 7% platelet lysate), porous tantalum scaffold group (MG63 cells were cultured on the domestic porous tantalum scaffold), and combined group (MG63 cells were cultured with 7% platelet lysate and porous tantalum scaffold. Scanning electron microscope was used to observe the surface morphology of domestic porous tantalum and platelet lysate-porous tantalum scaffold-MG63 cell complex. Cell counting kit-8 method was used to detect the proliferation of MG63 cells. Real-time fluorescence quantitative PCR (qPCR), immunocytochemical staining and western blot were used to detect the expression of ITGβ1, Vinculin, F-actin in MG63 cells at mRNA and protein levels. RESULTS AND CONCLUSION: Under the scanning electron microscope, MG63 cells adhered well to the scaffold surface. Compared with the blank group, the proliferation of MG63 cells could be significantly promoted by either platelet lysate or porous tantalum scaffold (P < 0.05). Moreover, the proliferation of MG63 cells was significantly improved in the combined group compared with the other three groups (P < 0.05). Findings from qPCR, immunocytochemical staining and western blot showed the highest expression of ITGβ1, Vinculin, F-actin mRNA and protein in the combined group (P < 0.05). These results indicate that platelet lysate and the domestic porous tantalum scaffold can synergistically promote the proliferation of MG63 cells, and up-regulate the expression of ITGβ1, Vinculin and F-actin mRNA and protein. Activation of the ITGβ1/Vinculin/F-actin signaling pathway may contribute to the proliferation, adhesion and differentiation of MG63 cells.

The diagnostic value of enhanced MRI of pituitary for pituitary stalk interruption syndrome and a correlation analysis between enhanced MRI and pituitary target gland function damage / 中国医学装备

Objective:To observe and research the diagnostic value of enhanced MRI of pituitary for pituitary stalk interruption syndrome (PSIS) and explore the correlation between enhanced MRI and pituitary target gland function damage.Methods: 80 patients with PSIS were divided into part of pituitary stalk interruption group (38cases) and complete pituitary stalk interruption group (42cases). And 80 healthy people were divided into control group. The relative hormonal level of three groups were detected, and the correlation between appearance of MRI and insufficient hormonal type, amount and severity degree were analyzed.Results: In part of pituitary stalk interruption group, the heights of anterior pituitary gland were less than 3mm in 10 cases, and they were between 3-5mm in 23 cases and they were more than 5mm in 5 cases. And in them, there were 4 cases were posterior pituitary deficiency, 15 cases were heterotopia, 11 cases were volume diminished. In complete pituitary stalk interruption group, the heights of anterior pituitary gland were less than 3mm in 23 cases, and they were between 3-5mm in 16 cases and they were more than 5mm in 3 cases. And in them, there were 8 cases were posterior pituitary deficiency, 32 cases were heterotopia, 1 cases were volume diminished. All of the hormonal levels included growth hormone, insulin-like growth factor, free thyroxine, serum thyroid stimulating hormone (TSH), cortisol and adrenocorticotrophic hormone (ACTH) in complete pituitary stalk interruption group were significantly lower than that in part of pituitary stalk interruption group and control group (F=224.92,F=2571.80, F=369.50,F=67.73,F=2677.94,F=24.17,P<0.05), respectively. The differences of growth hormone, TSH, cortisol and ACTH, excepted insulin-like growth factor and free thyroxine, between part of pituitary stalk interruption group and control group were not significant. And pituitary-gonadal hormones level of part of pituitary stalk interruption group was significantly lower than that of control group (F=354.94,F=247.00, F=247.83,F=655.05,F=48.10,P<0.05). Besides, the differences of follicle-stimulating hormone, luteinizing hormone, estradiol, testosterone and prolactin levels between part of pituitary stalk interruption group and complete pituitary stalk interruption group were no significant.Conclusion: Enhanced MRI of pituitary can effectively diagnose pituitary stalk interruption syndrome and damage degree of pituitary target gland function.

Rosiglitazone promotes apoptosis in colon cancer HT29 and HCT116cells through AKT/GSK3βsignalling pathway / 中国比较医学杂志

Objective To investigate the effect of rosiglitazone on the proliferation and apoptosis of colon cancer cells and the changes in the AKT/GSK3β signaling pathway. Methods Different concentrations of rosiglitazone ( 20. 0μmol/L, 40. 0 μmol/L, 80. 0 μmol/L) were used to treat colon cancer HT29 cells and HCT116 cells. Cell proliferation was detected by MTT assay. Annexin V FITC/PI cell death detection kit was used to test the cell apoptosis rate. The expression of apoptotic protein Bcl-2, Bax and Akt, GSK3β were detected by Western blot. Results Different concentrations of rosiglitazone had different effect on the proliferation of colon cancer cells compared with the blank control group, and showed a dose dependence (P< 0. 01). With the increase of rosiglitazone dose, the apoptosis-inducing effect @was increased dose-dependently (P< 0. 01). When the cells were treated with rosiglitazone for 48 h, the expressions of Bcl-2/Bax, p-GSK3β, and p-Akt were significantly decreased compared with the blank control group (P< 0. 01), but the expression level of Akt and GSK3β was not significantly different compared with the blank control group ( P > 0. 05 ) . Conclusions Rosiglitazone significantly induces apoptosis and inhibits the proliferation of HT29 cells. It may be via inhibiting Akt/GSK3β signaling pathway and change the ratio of Bcl-2/Bax.

Effects of Acupuncture Treatment on HPA Axis Related Hormones in Insomnia Rats / 中国中医药信息杂志

Objective To observe the effects of acupuncture treatment on the levels of HPA axis related hormones and acupoint compatibility in insomnia rats; To discuss the mechanism of action for acupuncture treatment. Methods Chlorophenylalanine suspension was under intraperitoneal injection to establish insomnia model rats. Sixty SD rats were randomly divided into blank group, model group, Baihui+Shenmen group, Baihui+Sanyinjiao group, Baihui+non-acupoint group, with 12 rats in each group. Each treatment group received acupuncture in relevant acupoints, 30 min each time, for 7 d. ELISA was used to measure the levels of CRH, ACTH and CORT. Results Compared with the model group, the levels of CRH, ACTH and CORT of the acupuncture groups decreased to some extent. In the three acupuncture groups, the efficacy of Baihui+Shenmen group was better than that of Baihui+Sanyinjiao group and Baihui+non-non-acupoint group. Conclusion Acupuncture treatment may calm and soothe the nerves to release the insomnia through regulating HPA axis related hormones. Acupuncture acupoints at different meridians may be one of the factors that cause the difference of acupoints compatibility effect.
