[Clinical Study of San Wei Sheng Huo Decoction in the Treatment of Refractory Chemotherapy-Induced Thrombocytopenia].

Objective: To investigate the efficacy and safety of treating refractory chemotherapy-induced thrombocytopenia (RCIT) with San Wei Sheng Huo Decoction (SWSHD) as the main formula. Methods: A retrospective study was conducted and the data of RCIT patients treated with SWSHD as the main formula were collected. Changes in peripheral blood platelet (PLT) levels at different time points of treatment were examined and the significant effective rate (SER) and effective rate (ER) were analyzed. We measured the increase in peripheral blood PLT count before and after treatment, analyzed the differences in PLT count increase for different degrees of RCIT treatment, and evaluated the safety of the treatment. Results: A total of 35 cases of RCIT were included in the study. With SWSHD as the main treatment formula, the 2-week ER and SER were 74.29% and 14.29%, respectively, the 2-month ER and SER were 84.38% and 60.50, respectively, and the 1-year ER and SER were 92.31% and 80.77%, respectively. PLT count increased at all time points after treatment compared with that before treatment ( P<0.01). Subgroup analysis showed that, 2 months after treatment started, peripheral blood PLT counts increased by as much as 51.02×10 9L －1 in the severe RCIT group, higher than that of the moderate RCIT group at 36.58×10 9L －1 ( P<0.05), and the difference persisted until 1 year after the treatment. No obvious traditional Chinese medicine-related adverse reaction was observed during the treatment. Conclusion: SWSHD takes effect rapidly and its effect is long-lasting and stable. Furthermore, SWSHD has a more significant effect on severe RCIT.

[Meta-analysis of efficacy and safety of Hulisan Capsules in treatment of knee osteoarthritis].

This study aims to assess the efficacy and safety of Hulisan Capsules in the treatment of knee osteoarthritis, which is expected to serve as a reference for clinical practice. To be specific, randomized controlled trial(RCT) on the treatment of knee osteoarthritis with Hulisan Capsules was retrieved from EMbase, PubMed, Cochrane Library, Web of Science, CNKI, Wanfang, SinoMed, and VIP(from inception to November 15, 2021). Two researchers independently screened the articles, extracted the data, and evaluated the risk of bias with ROB. RevMan 5.4 was used for Meta-analysis. Finally, 12 RCTs were screened out, involving 1 703 cases(1 075 in the experimental group and 628 in the control group). Meta-analysis showed that conventional treatment + Hulisan Capsules was superior to conventional treatment alone in terms of symptom relief rate(RR=1.19, 95%CI[1.09, 1.30], P<0.000 1), Lysholm score(MD=11.17, 95%CI[7.35, 15.00], P<0.000 01), visual analogue scale(VAS) score(MD=-0.99, 95%CI[-1.30,-0.68], P<0.000 01), and knee function score(RR=8.94, 95%CI[6.51, 11.37], P<0.000 01). Hulisan Capsules alone was superior to the conventional treatment alone in terms of the symptom relief rate(RR=1.38, 95%CI[1.13, 1.69], P=0.002) and knee function score(MD=2.88, 95%CI[0.81, 4.94], P=0.006), but VAS score was insignificantly different between the patients treated with Hulisan Capsules alone and those with conventional treatment alone(MD=-0.57, 95%CI[-1.42, 0.29], P=0.19). Hulisan Capsules + conventional treatment showed insignificant difference in symptom relief rate from the Zhuifeng Tougu Capsules + conventional treatment(RR=1.07, 95%CI[0.91, 1.25], P=0.44). The Lequesne score was insignificantly different between Hulisan Capsules + conventional treatment and conventional treatment/Zhuifeng Tougu Capsules + conventional treatment(MD=-2.17, 95%CI[-6.29, 1.96], P=0.30). The incidence of adverse reactions in the experimental group was significantly lower than control group(RR=0.57, 95%CI[0.34, 0.96], P=0.03). According to the available data and methods, Hulisan Capsules/Hulisan Capsules + conventional treatment could improve the symptom relief rate, Lysholm score, knee function score, and VAS score of patients with knee osteoarthritis, and alleviate the symptoms of pain, stiffness, and swelling of them. No serious adverse reactions were found yet. In the future, more large-sample and standard clinical trials are needed to verify the effect and safety of Hulisan Capsules in the treatment of knee osteoarthritis.

Petroleum contamination significantly changes soil microbial communities in three oilfield locations in Delta State, Nigeria.

Soil microbial community structure is altered by petroleum contamination in response to compound toxicity and degradation. Understanding the relation between petroleum contamination and soil microbial community structure is crucial to determine the amenability of contaminated soils to bacterial- and fungal-aided remediation. To understand how petroleum contamination and soil physicochemical properties jointly shaped the microbial structure of soils from different oilfields, high-throughput sequencing of 16S and ITS amplicons were used to evaluate the shifts of microbial communities in the petroleum-contaminated soils in Ughelli East (UE), Utorogu (UT), and Ughelli West (UW) oilfields located in Delta State, Nigeria. The results showed 1515 bacteria and 919 fungal average OTU number, and community richness and diversity, trending as AL > UT > UW > UE and AL > UW > UT > UE for bacteria, and AL > UW > UT > UE and UW > UT > AL > UE for fungi, respectively. The bacterial taxa KCM-B-112, unclassified Saccharibacteria, unclassified Rhizobiales, Desulfurellaceae, and Acidobacteriaceae and fungal Trichocomaceae, unclassified Ascomycota, unclassified Sporidiobolales, and unclassified Fungi were found to be the dominant families in petroleum-contaminated soils. Redundancy analysis (RDA) and Spearman's correlation analysis revealed that total carbon (TC), electric conductivity (EC), pH, and moisture content (MO) were the major drivers of bacterial and fungal communities, respectively. Gas chromatography-mass spectrophotometer (GC-MS) analysis exhibited that the differences in C7-C10, C11-C16, and C12-C29 compounds in the crude oil composition and soil MO content jointly constituted the microbial community variance among the contaminated soils. This study revealed the bacterial and fungal communities responsible for the biodegradation of petroleum contamination from these oilfields, which could serve as biomarkers to monitor oil spill site restoration within these areas. Further studies on these contaminated sites could offer useful insights into other contributing factors such as heavy metals.
