Network Meta-analysis of Qi-supplementing and Yin-nourishing Chinese patent medicines in treatment of early diabetic nephropathy / 中国中药杂志

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

Methods　Demographic information and drug susceptibility date of etiologically positive pulmonary tuberculosis patients in Changsha from 2018 to 2021 were collected, the successful rate of resistance screening, incidence and tendency in MDR-TB and pre-XDR-TB in patients included in this study were statistically analyzed accordingly. 　　Results From 2018 to 2021, the successful screening rates were 86.2%, 87.7%, 81.9% and 71.5% for MDR-TB and 82.2%, 84.8%, 76.9% and 68.2% for pre-XDR-TB, respectively. In each year, MDR-TB patients identified accounted for 7.6% (101/1 222), 6.5%(124/1 774), 6.6%(110/1 555) and 6.3%(99/1 478), and pre-XDR-TB patients identified accounted for 3.6%(46/1 219), 3.8%(69/1 766), 4.4%(69/1 495) and 4.6%(69/1 436), correspondingly. The incidence of MDR-TB showed a slowly downward trend, while the incidence of pre-MDR-TB showed a slowly upward trend, with neither decreasing nor increasing trends being statistically significant (（χ2=1.947，0.806，P>0.050). The incidence of MDR-TB in the retreatment failure population was 66.6% (2/3), and the others, failure initial treatment and recrudescence populations were 23.5% (19/81), 16.7% (2/12) and 15.2% (70/461), respectively. Similar to the incidence above, the incidence of pre-XDR-TB was 16.7% (2/12) among patients who failed in initial treatment, and 12.2% (9/74), 9.8% (43/439), and 4.5% (2/44) among the others, recrudescence and returned patients, respectively. The incidence rates of MDR-TB and pre-XDR-TB in different populations were significantly different (χ2=117.600，59.030，P<0.05). Conclusions There are still areas for improvement in tuberculosis drug resistance surveillance system in Changsha. On the premise of paying attention to patients in retreatment failure, other, initial treatment failure and relapse patients, high sensitivity molecular drug susceptibility testing, and scientifically efficient screening strategies must be explored.

Network Meta-analysis of oral Chinese patent medicines in treating type 2 diabetes mellitus complicated with angina pectoris of coronary heart disease / 中国中药杂志

Bayesian network Meta-analysis was employed to compare the efficacy of different oral Chinese patent medicines in treating type 2 diabetes mellitus with angina pectoris of coronary heart disease. Randomized controlled trial(RCT) of oral Chinese patent medicines in treating type 2 diabetes mellitus complicated with angina pectoris of coronary heart disease were retrieved from 8 Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, Cochrane Library, and Web of Science with the time interval from inception to November 2022. The BUGSnet package in R 4.2.1 was used to conduct Meta-analysis. A total of 45 RCTs were included, involving 4 727 patients and 7 oral Chinese patent medicines. Network Meta-analysis showed that the conventio-nal western medicine combined with Chinese patent medicines improved the outcome indicators. Shexiang Baoxin Pills + conventional western medicine had the best effect on reducing the incidence of adverse cardiovascular events, and Yixinshu Capsules + conventional western medicine on reducing the frequency and duration of angina pectoris. The conventional western medicine combined with oral Chinese patent medicines can reduce blood glucose indicators. Yindan Xinnaotong Soft Capsules + conventional western medicine had the best effect on reducing fasting blood glucose(FBG), 2 hours postprandial blood glucose(PBG), and glycosylated hemoglobin(HbA1c). The conventional western medicine combined with oral Chinese patent medicines can reduce blood lipid indicators. Yixinshu Capsules + conventional western medicine had the best effect on reducing total cholesterol(TC) and low density lipoprotein-cholesterol(LDL-C), and Yindan Xinnaotong Soft Capsules + conventional western medicine on reducing triglyceride(TG). Current evidence suggests that the patients with type 2 diabetes mellitus complicated with angina pectoris of coronary heart disease could reasonably choose oral Chinese patent medicines on the basis of routine antiplatelet, anticoagulant, hypoglycemic, and antihypertensive therapies, which could reduce the incidence of adverse cardiovascular events, alleviate the symptoms of angina pectoris, and reduce the glucose and lipid metabolism indicators. Shexiang Baoxin Pills + conventional treatment and Yixinshu Capsules + conventional western medicine have better effect on angina pectoris, Yindan Xinnaotong Soft Capsules + conventional western medicine on lowering blood glucose, and Yindan Xinnaotong Soft Capsules + conventional western medicine and Yixinshu Capsules + conventional western medicine on reducing blood lipid. Due to the lack of direct comparative results between Chinese patent medicines and other factors, high-quality studies remain to be carried out for further verification.

@#Abstract: Objective　To investigate the molecular characteristic and evolutionary trends of full-genome sequences of coxsackievirus A2 (CV-A2) and A5 (CV-A5) in Changsha City. Methods　The CV-A2 and CV-A5 strains were isolated and detected from patients with hand, foot and mouth disease (HFMD) cases. The full-genome sequences of CV-A2 and CV-A5 strains were obtained using NGS sequencing. Homology and phylogenetic tree analysis were performed, and the recombination regions of the strains were examined by SimPlot software. Results　The full-genome sequences of CV-A2 and CV-A5 strains were obtained from routine surveillance cases of HFMD in Changsha in 2019. The CV-A2 strain was named S281/Changsha/CHN/2019 with the full-genome sequence of 7 422 bp long; the CV-A5 strain was named S272/Changsha/CHN/2019 with the full-genome sequence of 7 425 bp long. Homology analysis of the isolates by comparison with the nucleic acid sequences of CV-A2 and other CV-A2 strains in China showed that the non-structural protein region shared lower similarity than that of structural protein region. The CV-A2 showed 79.20% similarity with Fleetwood strain (NC038306), showed the highest similarity 95.60% with MN419014 strain from Hubei Province. The non-structural protein 3C and 3D region shared the lowest similarity with MN419014, 90.51 and 92.06%, respectively. Phylogenetic tree analysis showed that 3C and 3D regions were located in the CV-A4 branch. Amino acid mutation sites were found in non-structural protein region, and the amino acid sequence in structural protein region was conserved. SimPlot analysis showed that genetic recombination was found in the 3C and 3D region of CV-A2 strains. The full-genome sequence of CV-A5 showed 80.7% similarity with the Swartz (AY421763) and 97.43% similarity with the strain (MH111030) from Australian. Homology analysis showed that the non-structural protein region shared lower similarity than that of structural protein region, based on full-genome of CV-A5. Phylogenetic tree analysis showed that CV-A5 and MH111030 were in the same branch, indicating that CV-A5 strain not from local. The amino acid sequence of CV-A5 strain was conserved.

Aim To establish subcutaneous and orthotopic transplantation models of human lung cancer in nude mice, and compare the anti-cancer effects of digoxin between the two models. Methods After subcutaneous inoculation of H460 tissues in nude mice, the tumor volume was measured; HE staining and immunohistochemistry were performed; H460-Luc cell suspension was injected into the lung of nude mice toestablish orthotopic tumor model, the in vivo imaging and fluorescence values were recorded, and the tumor lesions in other organs were observed after dissection. Results Compared with control group, the gemcitabine group had a significant anti-tumor effect (P 0.05). HE staining showed that the cell density in each treatment group decreased, and necrosis and/or fibrous hyperplasia were obvious. Immunohistochemistry indicated that the protein expression of p-p38, p-ERK and Nur77 in each treatment group significantly increased in the subcutaneous transplantation model; in the orthotopic transplantation model, the gemcitabine, the middle (P < 0.05) and low dose of digoxin group could inhibit the tumor growth, while the high dose of digoxin group accelerated the development of tumor (P < 0.05). Conclusion Digoxin is more sensitive to orthotopic transplanted tumor than subcutaneous transplanted tumor, anddigoxin may inhibit the tumor growth by up-regulating the expression of p-p38, pERK and Nur77.

The effect of preperitoneal pelvic packing for hemodynamically unstable patients with pelvic fractures / 中华创伤杂志(英文版)

PURPOSE@#Hemodynamically unstable patients with pelvic fractures still represent a challenge to trauma surgeons and have a very high mortality. This study was designed to explore the effect of the interventions of direct preperitoneal pelvic packing for the hemodynamically unstable pelvic fractures.@*METHODS@#This retrospective study enrolled 67 cases of severe pelvic fractures with unstable hemodynamics from October 2011 to December 2019. All patients presented in our emergency center and received preperitoneal pelvic packing were included in this study. The indication was persistent systolic blood pressure ≤90 mmHg during initial resuscitation and after transfusion of two units of red blood cells. Patients with hemodynamic stability who need no preperitoneal pelvic packing to control bleeding were excluded. Their demographic characteristics, clinical features, laboratory results, therapeutic interventions, adverse events, and prognostic outcomes were collected from digital information system of electronic medical records. Statistics were described as mean ± standard deviation or medium and analyzed using pair sample t-test or Mann-Whitney U-test.@*RESULTS@#The patients' average age was 41.6 years, ranging from 10 to 88 years. Among them, 45 cases were male (67.2%) and 22 cases were female (32.8%). Significant difference was found regarding the systolic blood pressure (mmHg) in the emergency department (78.4 ± 13.9) and after preperitoneal pelvic packing in the surgery intensive care unit (100.1 ± 17.6) (p < 0.05). Simultaneously, the arterial base deficit (mmol/L) were significantly lower in the surgery intensive care unit (median -6, interquartile range -8 to -2) than in the emergency department (median -10, interquartile range -14 to -8) (p < 0.05). After preperitoneal pelvic packing, 15 patients (22.4%) underwent pelvic angiography for persistent hypotension or suspected ongoing haemorrhage. The overall mortality rate was 29.5% (20 of 67).@*CONCLUSIONS@#Preperitoneal pelvic packing, as a useful surgical technique, is less invasive and can be very efficient in early intra-pelvic bleed control.

Microencapsulation of immunoglobulin Y: optimization with response surface morphology and controlled release during simulated gastrointestinal digestion / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Immunoglobulin Y (IgY) is an effective orally administered antibody used to protect against various intestinal pathogens, but which cannot tolerate the acidic gastric environment. In this study, IgY was microencapsulated by alginate (ALG) and coated with chitooligosaccharide (COS). A response surface methodology was used to optimize the formulation, and a simulated gastrointestinal (GI) digestion (SGID) system to evaluate the controlled release of microencapsulated IgY. The microcapsule formulation was optimized as an ALG concentration of 1.56% (15.6 g/L), COS level of 0.61% (6.1 g/L), and IgY/ALG ratio of 62.44% (mass ratio). The microcapsules prepared following this formulation had an encapsulation efficiency of 65.19%, a loading capacity of 33.75%, and an average particle size of 588.75 μm. Under this optimum formulation, the coating of COS provided a less porous and more continuous microstructure by filling the cracks on the surface, and thus the GI release rate of encapsulated IgY was significantly reduced. The release of encapsulated IgY during simulated gastric and intestinal digestion well fitted the zero-order and first-order kinetics functions, respectively. The microcapsule also allowed the IgY to retain 84.37% immune-activity after 4 h simulated GI digestion, significantly higher than that for unprotected IgY (5.33%). This approach could provide an efficient way to preserve IgY and improve its performance in the GI tract.

Activation of anthrachamycin biosynthesis in Streptomyces chattanoogensis L10 by site-directed mutagenesis of rpoB / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Genome sequencing projects revealed massive cryptic gene clusters encoding the undiscovered secondary metabolites in Streptomyces. To investigate the metabolic products of silent gene clusters in Streptomyces chattanoogensis L10 (CGMCC 2644), we used site-directed mutagenesis to generate ten mutants with point mutations in the highly conserved region of rpsL (encoding the ribosomal protein S12) or rpoB (encoding the RNA polymerase β-subunit). Among them, L10/RpoB (H437Y) accumulated a dark pigment on a yeast extract-malt extract-glucose (YMG) plate. This was absent in the wild type. After further investigation, a novel angucycline antibiotic named anthrachamycin was isolated and determined using nuclear magnetic resonance (NMR) spectroscopic techniques. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis and electrophoretic mobility shift assay (EMSA) were performed to investigate the mechanism underlying the activation effect on the anthrachamycin biosynthetic gene cluster. This work indicated that the rpoB-specific missense H437Y mutation had activated anthrachamycin biosynthesis in S. chattanoogensis L10. This may be helpful in the investigation of the pleiotropic regulation system in Streptomyces.

Research on relationship between occurrence of root rot and changes of fungal communities in rhizosphere of Panax quinquefolius / 中国中药杂志

The root rot disease is a common disease during the cultivation of Panax quinquefolius. In order to provide some clues for solving the root rot disease of P. quinquefolius, the relationship between rhizosphere soil fungal communities and root rot of P. quinquefolius was investigated in this study. The diversities and the changes of fungal communities structure in blank control group (group C), rhizosphere soil of healthy P. quinquefolius (group N) and occurrence of root rot in rhizosphere soil of P. quinquefolius (group R)were analyzed byusing the Illumina MiSeq high-throughput sequencing technology. A total of 505 968 high-quality sequences were obtained through high-throughput sequencing and the rare faction curves analysis showed that the sequencing depth was sufficient and the sampling was reasonable. The fungal communities structure of rhizosphere soil samples mainly belonged to 9 phylums including Ascomycota(54.9%), Basidiomycota(5.6%), etc., and the dominant specie was Ascomycota of the total fungal identified, respectively. The 115 genera of fungi were tested, including Monographella (3.9%), Archaeorhizomyces (3.9%), Mortierella, etc., and the dominant specie was Monographella. At the genus level, the abundance of Monographella and Mortierella in group R increased significantly compared with the abundance in groups C and N. Alpha diversity index of species showed that the diversity index of fungal communities reduced and the numbers of fungi reduced in group N and R, compared with group C, and reaching the minimum in group R. Beta diversity index of species showed that there was a significant difference in the fungal communities structure in each sample. In addition, the heat map analysis revealed that the dominant fungal genera were significantly different among the each sample. The proportion of Monographella and Mortierella in group R was significantly higher than that in group C and N, while the proportion of Trichoderma,Penicillium and Cadophora in group R was extremely low. The proportion of Phoma and Gibberella in group R increased significantly compared with group C. This study clarified the decline of diversity index and the imbalance of community structure in fungi may lead to the occurrence of root rot in P. quinquefolius by analysis of fungal diversity and community composition in the rhizosphere soil of P. quinquefolius in this study, which provided a theoretical basis for the prevention and treatment of occurrence of root rot in P. quinquefolius.

Comparison of diagnosis value of double-balloon endoscopy and single-balloon endoscopy in diagnosing small intestinal diseases / 中国内镜杂志

Objective To compare the diagnosis value of double-balloon endoscopy (DBE) and single-balloon endoscopy (SBE) in diagnosing small intestinal diseases. Methods 117 cases with suspected small intestinal diseases from Jul 2014 to Aug 2016 were divided into DBE group (n = 68) and SBE group (n = 49) according to the treatment methods. These indexes as followed were compared between the two groups: procedure duration, intubation depth, detection rate, endoscopic treatment rate, and the detection rates in different chief complaints and diseases. The safety assessment was analyzed. Results Through the mouth and the anus examinations, DBE and SBE groups produced no significant differences in procedure duration, intubation depth, detection rate, and endoscopic treatment rate (P > 0.05). The unknown causes gastrointestinal bleeding, abdominal pain, diarrhea and other detection rate of small intestine disease compare differences had no statistical significance (P > 0.05), none in crohn's disease, malignant tumor, benign tumor, small enteritis, ulcers, polyps, diverticulum and tuberculosis (P > 0.05). There were no serious complications occurred in both groups. Conclusion DBE and SBE have the similar detection rate of small intestine diseases.
