[Network Meta-analysis of efficacy of seven Chinese patent medicines in treatment of inflammatory response in chronic glomerulonephritis].

This study aimed to evaluate the efficacy and safety of various Chinese patent medicines in the treatment of inflammatory response in chronic glomerulonephritis(CGN) based on network Meta-analysis. Randomized controlled trial(RCT) of oral Chinese patent medicines for improving inflammatory response in patients with CGN was retrieved from databases such as CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science from database inception to March 2023. All investigators independently screened the literature, extracted data, and evaluated the quality. Stata 16.0 and RevMan 5.4.1 software were used to analyze the data of the literature that met the quality standards. Finally, 71 RCTs were included, involving 7 Chinese patent medicines. The total sample size was 6 880 cases, including 3 441 cases in the test group and 3 439 cases in the control group. The network Meta-analysis showed that(1) in terms of reducing TNF-α, the top 3 optimal interventions according to the surface under the cumulative ranking curve(SUCRA) were Shenyanshu Capsules/Granules/Tablets+conventional western medicine, Huangkui Capsules+conventional western medicine, and Bailing Capsules+conventional western medicine.(2) In terms of reducing hs-CRP, the top 3 optimal interventions according to SUCRA were Yishen Huashi Granules+conventional western medicine, Huangkui Capsules+conventional wes-tern medicine, and Bailing Capsules+conventional western medicine.(3) In terms of reducing IL-6, the top 3 optimal interventions according to SUCRA were Yishen Huashi Granules+conventional western medicine, Bailing Capsules+conventional western medicine, and Shenyan Kangfu Tablets+conventional western medicine.(4) In terms of reducing 24hUTP, the top 3 optimal interventions according to SUCRA were Shenyan Kangfu Tablets+conventional western medicine, Bailing Capsules+conventional western medicine, and Huangkui Capsules+conventional western medicine.(5) In terms of reducing Scr, the top 3 optimal interventions according to SUCRA were Bailing Capsules+conventional western medicine, Shenyanshu Capsules/Granules/Tablets+conventional western medicine, and Yishen Huashi Granules+conventional western medicine.(6) In terms of reducing BUN, the top 3 optimal interventions according to SUCRA were Yishen Huashi Granules+conventional western medicine, Shenyanshu Capsules/Granules/Tablets+conventional western medicine, and Bailing Capsules+conventional western medicine.(7) In terms of improving the clinical total effective rate, the top 3 optimal interventions according to SUCRA were Huangkui Capsules+conventional western medicine, Kunxian Capsules+conventional western medicine, and Yishen Huashi Granules+conventional western medicine. The results showed that the combination of conventional western medicine and Chinese patent medicine could reduce the expression of serum inflammatory factors TNF-α, hs-CRP, and IL-6 and inhibit the inflammatory response. The combination of conventional western medicine and Chinese patent medicine was superior to conventional western medicine alone in reducing Scr, BUN, and 24hUTP, and improving the clinical total effective rate of treatment. Due to the limitation of the quantity and quality of literature included, the above conclusions need to be validated by more high-quality studies.

Population growth of Tetranychus truncatus (Acari: Tetranychidae) on different drought-tolerant potato cultivars.

Tetranychus truncatus Ehara (Acari: Tetranychidae) has become one of the major phytophagous pests in China in recent years, and is found on a wide range of host plants. However, little information is available on the population performance of this arthropod pest on potatoes. In this study, we explored the population growth of T. truncatus on two drought-tolerant potato (Solanum tuberosum L.) cultivars under laboratory conditions using the age-stage, two-sex life table. Tetranychus truncatus completed its entire life history on both potato cultivars tested, Holland 15 and Longshu 10. There was no significant difference between two potato cultivars in developmental duration. Tetranychus truncatus had shorter adult longevity (20.61 days), adult female longevity (20.41 days), and total female longevity (33.66 days) on Longshu 10 than Holland 15 (21.16 days, 21.19 days, and 34.38 days, respectively). However, it exhibited a higher preadult survival rate, higher fecundity (F = 88.32 eggs per female), and relatively higher population parameters when reared on Longshu 10 than on Holland 15 (F = 75.70 eggs per female). Growth projection also showed that the population size of T. truncatus on Longshu 10 (expand 750-fold) was larger than that on Holland 15 (expand 273-fold) after 60 days. Our results demonstrate that the drought-sensitive potato variety, Holland 15, is relatively resistant to T. truncatus compared with the drought-tolerant variety, Longshu 10, and suggest that T. truncatus exhibited a trade-off between longevity and reproduction on both potato cultivars. Our findings provide information on population prediction, which may aid the management of this pest mite species of potatoes.

METHODS: The clinical data of 38 patients with super-high-risk prostate who underwent transurethral surgery in our hospital from April 2016 to December 2017 were retrospectively analyzed. All patients had obvious progressive dysuria. The diagnosis of benign prostatic hyperplasia was confirmed by urinary color Doppler ultrasound, anal finger examination, PSA, prostate biopsy, etc., and prostate cancer was excluded. Each patient was aged ≥85 years old and combined with one or more types. Senile basic diseases such as diabetes, hypertension, coronary heart disease, emphysema, sequelae of cerebral infarction, etc. The patients were randomly divided into two groups. The observation group was treated with transurethral 1470 nm semiconductor laser vaporization and the control group was treated with transurethral plasma electrotomy. To observe the changes of vital signs, bleeding, duration of surgery, postoperative bladder irrigation time, urinary catheter retention time, and changes of hemoglobin before and after surgery. Surgical safety. The international prostate symptom score (IPSS), quality of life score (QoL), maximum urinary flow rate (Qmax), and post-void residual urine volume (PVR) were evaluated 2 months after surgery and compared with preoperative evaluation to evaluate the surgical outcome. RESULTS: All 38 operations were successfully completed.The vital signs of the patients were stable during the operation. The average operation time of the observation group and the control group was (79.6±24.7 vs 69.5±19.8) min, P>0.05. The hemoglobin decreased by (6.9±3.0) g/L vs (13.2±4.0) g/L， after operation.P<0.05; postoperative bladder irrigation time (14.7±2.8 vs 23.5±5.3)h, P<0.05; average postoperative urinary catheter retention time (3.8±0.4 vs 5.7±0.9)d, P<0.05; average postoperative hospital stay (5.3±1.1 vs 7.2±1.9)d, P<0.05; all patients were followed up for 2 months, IPSS, QoL, Qmax, PVR and other indicators were significantly improved compared with preoperative, no major bleeding, urinary incontinence, cardiopulmonary failure and Significant urinary tract irritation symptoms occur. CONCLUSION: Compared with plasma electric resection, transurethral 1470 nm semiconductor laser treatment of benign prostatic hyperplasia has the advantages of high safety and remarkable effect, especially suitable for patients with high age and high risk.

Antioxidant Effects and Cytoprotective Potentials of Herbal Tea against H2O2-Induced Oxidative Damage by Activating Heme Oxygenase1 Pathway.

Herbal tea with antioxidant ingredients has gained increasing attention in the field of functional foods due to their amelioration potential in aging-related diseases. Wanglaoji herbal tea (WHT) is a kind of traditional beverage made from herbal materials. This study was performed to investigate its antioxidant activity and identify its protective effect on a H2O2-induced cell damage model. In this study, we identified six kinds of phenolic acids with antioxidant activity in WHT, among which rosmarinic acid had the highest content and the highest contribution ratio to the antioxidant activity of WHT. Moreover, compared with the H2O2-induced damage group, the WHT treatment group can significantly increase the viability of cells and decrease the ratio of senescence-associated ß-galactosidase-positive cells, intracellular malondialdehyde levels, and the percentage of G1 phase. Furthermore, enrichment analysis of differentially expressed genes revealed that heme oxygenase1 (HMOX1) was a key gene for protective effect of WHT on oxidative stress-induced cell damage. Thus, WHT exerted protective effects not only by scavenging reactive oxygen species but also by inducing the expression of cytoprotective genes by activating the HMOX1 pathway, which showed that WHT had a potential of promoting health by reducing oxidative stress-induced cell damage.

Cardamine komarovii flower extract reduces lipopolysaccharide-induced acute lung injury by inhibiting MyD88/TRIF signaling pathways.

In the present study, we investigated anti-inflammatory effect of Cardamine komarovii flower (CKF) on lipopolysaccharide (LPS)-induced acute lung injury (ALI). We determined the effect of CKF methanolic extracts on LPS-induced pro-inflammatory mediators NO and prostaglandin E2 (PGE2), production of pro-inflammatory cytokines (IL-1ß, TNF-α, and IL-6), and related protein expression levels of MyD88/TRIF signaling pathways in peritoneal macrophages (PMs). Nuclear translocation of NF-κB-p65 was analyzed by immunofluorescence. For the in vivo experiments, an ALI model was established to detect the number of inflammatory cells and inflammatory factors (IL-1ß, TNF-α, and IL-6) in bronchoalveolar lavage fluid (BALF) of mice. The pathological damage in lung tissues was evaluated through H&E staining. Our results showed that CKF can decrease the production of inflammatory mediators, such as NO and PGE2, by inhibiting their synthesis-related enzymes iNOS and COX-2 in LPS-induced PMs. In addition, CKF can downregulate the mRNA levels of IL-1ß, TNF-α, and IL-6 to inhibit the production of inflammatory factors. Mechanism studies indicated that CKF possesses a fine anti-inflammatory effect by regulating MyD88/TRIF dependent signaling pathways. Immunocytochemistry staining showed that the CKF extract attenuates the LPS-induced translocation of NF-kB p65 subunit in the nucleus from the cytoplasm. In vivo experiments revealed that the number of inflammatory cells and IL-1ß in BALF of mice decrease after CKF treatment. Histopathological observation of lung tissues showed that CKF can remarkably improve alveolar clearance and infiltration of interstitial and alveolar cells after LPS stimulation. In conclusion, our results suggest that CKF inhibits LPS-induced inflammatory response by inhibiting the MyD88/TRIF signaling pathways, thereby protecting mice from LPS-induced ALI.

[Community Dynamics of Phytoplankton and Related Affecting Factors in a Eutrophicated Small Pond].

The high-density sampling of eutrophic water can help to reveal the general rules of phytoplankton community succession and the relationship with environmental factors. The species and abundance of plankton and the physical-chemical factors were tracked for 30 weeks from March to October in a eutrophicated small pond. The relationships between the phytoplankton community dynamic change and the physical-chemical factors as well as the zooplankton in the water body community were studied by the multivariate statistical analysis with PRIMER. A total of 54 phytoplankton and 55 zooplankton species were identified, and the abundances of plankton varied from 0.28 x 10(8) - 6.11 x 10(8) cells x L(-1) for phytoplankton and 26-2.5 x 10(5) ind x L(-1) for zooplankton. The dominant species of phytoplankton were Cyanophyta and Chlorophyta, and an obvious succession process was showed with the seasonal change, which could be roughly divided into three stages: Chlorophyta-Cryptophyta type, Chlorophyta-Cyanophyta type and Cyanophyta type. BIO-ENV showed that pH, water temperature, transparency, total phosphorus and the abundances of Rotifera and Copepoda were the most critical influencing factors on the community dynamics of phytoplankton, and compared to zooplankton, the physical-chemical factors might have a greater influence.
