[Academic characteristics of contemporary famous traditional Chinese medicine experts and schools in treatment of chronic renal failure based on SrTO].

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.

Efficacy of Traditional Chinese Medicine on Animal Model of IgA Nephropathy: A Systematic Review and Meta-Analysis.

Objective: Traditional Chinese medicine (TCM) has a long history in the treatment of Immunoglobulin A nephropathy (IgAN). A large number of animal experiments focused on the TCM treatment of IgAN are conducted every year. The evidence for these preclinical studies is not clear. This study summarized and evaluated the results of animal experiments on TCM treatment for IgAN. Methods: We systematically searched animal studies from 6 databases from inception to August 30, 2022. We included Chinese studies from the key magazine of China technology. The quality of the included studies was evaluated with the SYRCLE animal experimental bias risk assessment tool and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: Out of 832 records identified in the initial search, 30 studies were selected. The results indicated that, compared with the control group, the TCM treatment group improved 24 h urine protein (24 h-UP) level (standardized mean difference (SMD) 3.57, 95% confidence interval (CI) 4.48 to 2.66, P < 0.001), urine red blood cell (U-RBC) (SMD 13.66, 95% CI 17.99 to 9.32, P < 0.001), serum creatinine (Scr) (mean difference (MD) 10.89, 95% CI 17.00 to 4.77, P < 0.001), blood urea nitrogen (BUN) (MD 2.44, 95% CI 3.42 to 1.47, P < 0.001), tumor necrosis factor-α (TNF-α) (MD 171.28 to 95% CI 323.68 to 18.88, P=0.03), transforming growth factor-ß1 (TGF-ß) (SMD 4.02, 95% CI 7.26 to 0.77, P=0.02), matrix metalloproteinase-9/tissue inhibitors of metalloproteinase-1(MMP-9/TIMP-1) (MD 0.03, 95% CI 0.00 to 0.06, P=0.02), nephrin mRNA (SMD 3.39, 95% CI 2.59 to 4.18, P < 0.001). However, there is no difference in albumin level (MD 1.10, 95% CI 0.06 to 2.26, P=0.06) and interleukin-6 (IL-6) (MD 170.77, 95% CI 365.3 to 23.75, P=0.09). Conclusions: TCM can improve 24 h-UP, U-RBC, Scr, BUN, MMP-9/TIMP-1, TNF-α, TGF-ß, and nephrin mRNA of IgAN animal models. Moreover, there is a need for rigorous reporting of preclinical research methodology, which is essential to support the quality of preclinical research. Registration.

New-onset glucose disorders in peritoneal dialysis patients: a meta-analysis and systematic review.

BACKGROUND: Peritoneal dialysis (PD) patients are at high risk of developing glucose metabolism disturbance (GMD). The incidence and prevalence of new-onset GMD, including diabetes mellitus (DM), impaired glucose tolerance (IGT) and impaired fast glucose (IFG), after initiation of PD, as well as their correlated influence factors, varies among studies in different areas and of different sample sizes. Also, the difference compared with hemodialysis (HD) remained unclear. Thus we designed this meta-analysis and systematic review to provide a full landscape of the occurrence of glucose disorders in PD patients. METHODS: We searched the MEDLINE, Embase, Web of Science and Cochrane Library databases for relevant studies through September 2018. Meta-analysis was performed on outcomes using random effects models with subgroup analysis and sensitivity analysis. RESULTS: We identified 1124 records and included 9 studies involving 13 879 PD patients. The pooled incidence of new-onset DM (NODM) was 8% [95% confidence interval (CI) 4-12; I2 = 98%] adjusted by sample sizes in PD patients. Pooled incidence rates of new-onset IGT and IFG were 15% (95% CI 3-31; I2 = 97%) and 32% (95% CI 27-37), respectively. There was no significant difference in NODM risk between PD and HD [risk ratio 0.99 (95% CI 0.69-1.40); P = 0.94; I2 = 92%]. PD patients with NODM were associated with an increased risk of mortality [hazard ratio 1.06 (95% CI 1.01-1.44); P < 0.001; I2 = 92.5%] compared with non-DM PD patients. CONCLUSIONS: Around half of PD patients may develop a glucose disorder, which can affect the prognosis by significantly increasing mortality. The incidence did not differ among different ethnicities or between PD and HD. The risk factor analysis did not draw a definitive conclusion. The glucose tolerance test should be routinely performed in PD patients.

[Evaluation of the capacity of personal protection on poison emergency items in Chinese disease control and prevention institutes].

OBJECTIVE: To analyze the capacity of personal protection on poison emergency items in Chinese disease control and prevention institutes. METHODS: Evaluation analysis based on data obtained from investigating personal protection equipments and professional knowledge quizzing about personal protection in poisoning control of 57 different level centers for disease control and prevention selected from China by a multi-stage stratified sampling. RESULTS: All 80.70% of the institutes possessed the protection equipments, provincial, municipal, county level institutes were 100.00%, 95.24%, 66.67%, respectively, with significant statistical difference (H = 7.94, P < 0.05). The average level of the type of individual protective equipments in disease control and prevention institutes was (5.42 +/- 4.00) kinds, the average points in category of provincial, municipal, county level institutes were (11.33 +/- 3.67), (6.52 +/- 3.16), (3.47 +/- 3.10) kinds, being statistically significant (F = 17.30, P < 0.05); type difference counts of disease control and prevention institutes in economic development, secondary, less-developed regions were (6.41 +/- 4.03), (3.55 +/- 3.35), (6.45 +/- 4.07) kinds, with statistical significance (F = 3.70, P < 0.05). Protection equipments chiefly possessed were latex gloves, gauze masks and C-protective clothing. Protective clothing and respiratory protective equipments were insufficient evidently. The average points in testing personal protection basic knowledge were (71.39 +/- 12.52) points; there were no differences between different institutes with different economic regions, levels, technical posts and title degrees. CONCLUSION: Certain advances have been achieved in recent years in personal protection capacity of institutes for disease control and prevention, but far from the actual demands, and maybe no enough effective response on emergency occurred.

[Toxicokinetics of tetramethylene disulphotetramine].

OBJECTIVE: To explore toxicokinetics of tetramethylene disulphotetramine (TETS) in rabbit and the effects on toxicokinetics of TETS after activated charcoal by gavage. METHODS: Eight rabbits were exposed through gavage and vein respectively, the blood samples were collected from the center artery in ear of rabbit at an arranged time. Four rabbits were exposed after being intubated into urethra and common bile duct. The samples of bile and urine were collected at arranged times. After being exposed by gavage, activated charcoal (1 g/kg) was administrated in the activated charcoal group and the distilled water (1 g/kg) administrated to the controls. The samples of blood were collected from the center artery in ear of rabbit at arranged times. The contents of TETS in samples were determined by GC/NPD method. Analysed by the 3p87 soft, toxicokinetics parameters of TETS were acquired. RESULTS: TETS was eliminated very slowly in rabbit. The plasma half time in elimination phase (Tke1/2) of TETS was 56.9 hours in vein exposure group and 262.5 hours in oral exposure group respectively. The plasma clearance (CL) of it was only 15.4 ml.kg(-1).h(-1) in oral exposure group and 24.1 ml.kg(-1).h(-1) in vein exposure group. TETS was eliminated from urine in rabbit. The eliminated amount of it from urine was more 5 times than from bile. All parameters of toxicokinetics of TETS were significantly different between the activated charcoal group and the control. Compared to the control, Tke1/2 of TETS in the activated charcoal group was equal to 55%, CL was increased over 3-fold, area under the curve was equal to 30%. CONCLUSION: TETS was a poison eliminated very slowly in body. The eliminated amount of it from urine was more than from bile. The excretion of TETS could be quickened after activated charcoal by gavage.

[Evaluation of therapeutic project on acute tetramethylene disulphotetramine poisoning and effect on intelligence in children].

OBJECTIVE: To evaluate four therapeutic measures on acute tetramethylene disulphotetramine (TETS) poisoning and the effects of it on intelligence of children. METHODS: All 86 patients of acute TETS poisoning were randomly divided into 4 groups (the control group, sodium valproate group, sodium dimercaptopropane sulfonate group and the hemoperfusion group). The therapeutic effects were observed after the arranged treatment was administrated. According to age, residence, sex, education and domestic economy, 30 children were matched by 1:1 with children of TETS poisoning. RESULTS: The termination time of seizure, doses of diazepam, mental symptoms and the continual time of mental symptoms were not significantly different among these three groups. After hemoperfusion, the seizure of patients was terminated or the frequency was obviously decreased, but the level of TETS in blood was not reduced. The average scores of full intelligence quotient (FIQ), the verbal intelligence quotient (VIQ) and the performance intelligence quotient (PIQ) of children in poisoning group were 9.1, 8.8 and 7.7 less than the controls. The average scores of FIQ of children with bad state were 15 less than the controls. CONCLUSION: Therapeutic effects of sodium valproate and sodium dimercaptopropane sulfonate on acute TETS poisoning should be not better than using diazepam and sodium phenobarbital. Therapeutic effects of hemoperfusion on TETS poisoning is good. TETS poisoning should have a great influence on intelligence of children.

[Study on the cloning goat by cross-breed somatic cell nuclear transfer].

UNLABELLED: Shaneng goat is a famous milking species. Boer goat is world famous goat breed for creophagism. In this study, we evaluated the development potential of adult Boer goat's somatic nuclei after nuclear tansfer (NT) into enucleated MII oocytes of the Shaneng goat. Somatic donor cells were obtained from two different sources: 1) adult granulosa cells (GCs) and 2) adult skin fibroblasts (FCs). The reconstructed embryos that developed to morula or blastocyst stage in vivo were transferred to 38 synchronized recipient. CONTROL: Somatic donor fibroblast cells were obtained from a fetal at 35 day. In the same way the reconstructed embryos were directly transferred to synchronized recipient of Shaneng goats. (1) Experimental group: NT embryos derived from GC and FC developed into morulas and blastocysts at a frequency of 46.8% and 31.4% respectively. Fifty-two NT morula and blastocyst stage embryos were transferred in to 38 recipients, Three of which were confirmed to be pregnant (7.9%). All pregnancies were not maintained to term. (2) CONTROL group: 136 NT embryos were transferred in to 14 recipients, Six of which were confirmed to be pregnant (42.9%). Four of those were maintained to term. Four recipients delivered four male kids (2.9% of embryos transferred). One male kid died at birth, the dead lamb shows as "large offspring syndrome". the others appeared health and normal. DNA analysis confirmed that those kids were genetically identical to their donor. These results demonstrated that Shaneng goat somatic cells could direct normal development and Shaneng goat oocyte cytoplasm supported development of preimplantation embryos produced by NT of somatic cell nuclei from Boer goat.
