ABSTRACT

Myzus persicae (Sulzer, Hemiptera: Aphididae) is a major global crop pest; it is the primary aphid vector for many damaging viruses and has developed resistance to most insecticides. In temperate regions, the risk of widespread crop infection and yield loss is heightened following warm winters, which encourage rapid population growth and early flight. Estimates of the frequency and magnitude of warm winters are, therefore, helpful for understanding and managing this risk. However, it is difficult to quantify the statistical distribution of climate events, particularly extremes, because climate observations represent just a small sample of the possible climate variations in a region. The purpose of this study was to establish a large-scale relationship between temperature and M. persicae observations across the UK and apply this to a very large ensemble of climate model simulations, which better sample the variability in climate, to quantify the current likelihood of extreme early M. persicae flight across the UK. The timing of M. persicae flight was shown to be significantly related to January-February mean temperature, where a 1°C warmer/cooler temperature relates to about 12 d earlier/later flight. Climate model simulations predict 40% likelihood of experiencing a year with unprecedented early M. persicae flight during the next decade in the UK. Results from this method can help crop managers assess the long-term viability of crops and management practices across the UK and provide early warning information for targeting pest surveillance activities on the locations and timings at highest risk of early M. persicae flight.

ABSTRACT

Cancer is a leading cause of premature death and disability in Samoa. Recognizing the importance of symptom awareness and early detection, the Samoa Cancer Society (SCS) developed the ‘Vave’ (quickly) campaign as the first multi-media cancer awareness campaign in Samoa. The campaign adopted a three-pronged community engagement approach including mass media; printed resources; and community outreach at culturally appropriate locations including churches, villages and schools. The campaign promoted three key messages: detect signs and symptoms quickly; quickly see a doctor; and quickly call SCS. To measure impact, data were collected using several methods around the outreach education sessions (pre- and post-surveys), campaign recall (survey) and Vave-related enquiries received by SCS. The findings revealed the campaign was effective in increasing awareness of cancer and importance of early detection demonstrated through community recall of campaign messages, increased enquiries to SCS and improved knowledge. However, it is of note that almost 30% of campaign recall respondents stated they were unsure or would not see a doctor if concerned about a sign of cancer. The reasons given being a lack of knowledge, lack of trust in hospitals and preference for traditional healing. This suggests more targeted culturally sensitive strategies are needed including partnering with traditional healers. Further, advocacy efforts are needed to address the structural barriers to cancer detection and treatment together with continuing education around causes and symptoms of cancer targeting the hard-to-reach communities in Samoa.

ABSTRACT

This study aimed to observe the intervention effect of Jianpi Huogu Formula(JPHGF) on the functional damage of vascular endothelial cells caused by glucocorticoid, and explore its action mechanism from the PI3 K/Akt and mitogen activated protein kinase(MAPK) signaling pathways. The extracted thoracic aorta ring of normal SD rats were intervened first with vascularendothelial growth factor(VEGF, 20 μg·L-1) and/or sodium succinate(MPS, 0. 04 g·L-1) in vitro and then with JPHGF(8, 16, and 32 μg·L-1) for five mcontinuous ethylpdays, rednisolofollowed nebythe statistics of the number, length, and area of microvessels budding fromvascular rings. In addition, the human umbilical vein endothelial cells(HUVECs) induced by VEGF(20 μg·L-1) were added with MPS(0. 04 g·L-1) and then with JPHGF(8, 16, and 32 μg·L-1) for observing the migration, invasion, and luminal formation abilities of HUVECs in the migration, invasion and luminal formation experiments. The protein expression levels of PI3 K, p-Akt, p-JN K, and p-ERK in HUVECs were assayed by Western blot. The results showed that JPHGF dose-dependently improved the num-ber,length, and area of microvessels in MPS-induced rat thoracic aortic ring, reversed the migration, invasion and lumen formation abiliti es of HUVECs reduced by MPS, and up-regulated the protein expression levels of PI3 K, p-Akt, and p-JNK in HUVECs. All thesehave suggested that JPHGF exerts the protective effect against hormone-induced damage to the angiogenesis of vascular endothelial cells by activating the PI3 K/Akt and MAPK signaling pathways, which has provided reference for exploring the mechanism of JPHGF in treating s teroid-induced avascular necrosis of femoral head(SANFH) and also the experimental evidence for enriching the scientific connotationof spleen-invigorating and blood-activating therapy.

ABSTRACT

By the in-depth excavation of prescriptions containing herbal pair Acori Tatarinowii Rhizoma-Polygalae Radix in the Dictionary of Traditional Chinese Medicine Prescriptions, this study analyzed their formulation rules, so as to provide reference for their clinical application and new drug development. First, the prescriptions containing Acori Tatarinowii Rhizoma-Polygalae Radix were collected from the Dictionary of Traditional Chinese Medicine Prescriptions, and their indications, herbal compatibility, and dosage forms were analyzed statistically using the Traditional Chinese Medicine Inheritance Support System(TCMISS). Meanwhile, the formulation rules and common dosage forms for the top four indications(amnesia, palpitation, mania, and epilepsy) sorted by frequency were analyzed with Apriori algorithm. A total of 507 prescriptions containing Acori Tatarinowii Rhizoma-Polygalae Radix were screened out, involving 15 indications(frequency>10) like amnesia, palpitation, mania, and epilepsy. There were 30 commonly used Chinese herbs(frequency≥60), with the Qi-tonifying herbs(Ginseng Radix et Rhizoma and Glycyrrhizae Radix et Rhizome), mind-tranquilizing herbs(Poria and Poria cum Radix Pini), and Yin-nourishing herbs(Angelicae Sinensis Radix and Ophiopogonis Radix) being the core ones. The commonly used dosage forms were honey pill, paste pill, decoction, and powder. These have indicated that the herbal pair Acori Tatarinowii Rhizoma-Polygalae Radix is often combined with Qi-tonifying, Yin-nourishing, and mind-tranquilizing herbs for the treatment of "heart or brain diseases" caused by phlegm production due to spleen deficiency, Qi and blood deficiency, and phlegm-turbidity blocking orifice. In the treatment of amnesia, supplementing essence and replenishing marrow are considered on the basis of tonifying Qi, nourishing Yin, and tranquilizing mind. In the treatment of palpitation and mania, tranquilizing mind is emphasized. In the treatment of epilepsy, the emphasis is placed on resolving phlegm, extinguishing wind, and stopping convulsion.

ABSTRACT

This clinical value-oriented comprehensive evaluation of drugs was carried out in accordance with Guidelines for Management of Comprehensive Clinical Evaluation of Drugs(trial version 2021), with the qualitative and quantitative evaluation methods adopted. Based on the evidence-based medicine, epidemiology, clinical medicine, pharmacoeconomics, mathematical statistics, and health technology evaluation(HTA), the clinical value of Ginkgolide Injection was evaluated from the "6+1" dimension by giving weight to the criterion level and index level and calculating with multi-criteria decision analysis(MCDA) model and CSC v2.0. After entering the market, Ginkgolide Injection has been subjected to phase Ⅳ clinical trial, spontaneous reporting system(SRS)-based data monitoring, systematic review and Meta-analysis, acute toxicity and long-term toxicity assays, active monitoring, and RCTs, and the evidence of safety was sufficient. The results of active monitoring showed that the incidence of adverse reactions was 0.09%(rare), mainly manifested as flushing, dizziness, rash, nausea, and vomiting. According to the nested case-control study, the adverse reactions of this drug had nothing to do with the product batch, implying that the drug quality was controllable. The adverse reactions mainly resulted from the pharmacodynamic reactions. Because the drug was effective in resisting platelet aggregation, the resulting adverse reactions such as flushing, dizziness, headache, and phlebitis were caused by vasodilation. Skin rash and gastrointestinal symptoms were mainly attributed to the patients’ sensitivity to drugs and their own allergic constitution. According to the sufficiency of evidence and the incidence of adverse reactions in the safety research, the safety of Ginkgolide Injection was grade A. The results of Meta-analysis showed that Ginkgolide Injection combined with conventional western medicine was superior to conventional western medicine in improving the clinical effective rate, neurological function score, and activity of daily living score of patients with cerebral infarction. The validity evidence was evaluated according to the PICO principle to be high. According to the GREAD evaluation principle, the quality of such evidence as clinical effective rate, National Institute of Health stroke scale(NIHSS), and Barthel Index(BI) was evaluated, and the results demonstrated that the evidence quality of clinical effective rate and activity of daily living score was medium. The effectiveness of Ginkgolide Injection was grade A. According to the economic report of Ginkgolide Injection, it had short-term and long-term pharmacoeconomic advantages in the treatment of ischemic stroke, and the economic evidence value was good. According to the CASP economic evaluation checklist, the overall quality evaluation results of the economic report are basically clear. To be specific, the economic evidence quality was high. Based on the comprehensive economic evidence quality and economic value, the economy of this drug was grade A. The innovation of this product was evaluated from three aspects: clinical innovation, enterprise service system innovation, and industrial innovation. Ginkgolide Injection could be used 24 h after intravenous thrombolysis for improving patients’ neurological function without increasing bleeding, indicating its important clinical innovation. There were many innovations in ensuring drug supply, especially at the grass roots, drug safety, effectiveness, and reasonable price, which has provided reference for establishing enterprise philosophy, managing drug resources, developing process and technology, and determining enterprise management and marketing. Therefore, its innovation was grade A. The drug had no special medication plan in use, exhibiting good suitability for doctors, nurses, and patients. The suitability was grade B. Compared with similar drugs, its price was at a medium level, meaning good affordability, sufficient production capacity, and easy accessibility. Its accessibility was therefore grade B. This drug belonged to Chinese medicinal injection. The large-sample real-world research revealed rich human use experience, so it was grade C for the traditional Chinese medicine characteristic. According to the comprehensive evaluation, the clinical value of Ginkgolide Injection in the treatment of cerebral infarction fell into class A. It is suggested that it can be transformed into the relevant policy results of basic clinical medication management according to the procedure.

ABSTRACT

To evaluate the application of endoscopic thyroidectomy using gasless axillary approach (ET-GA) for low-risk papillary thyroid carcinoma (PTC). Patients with T1N0M0 Ⅰ PTC undergoing unilateral thyroid lobectomy with central neck dissection in Taizhou Cancer Hospital during January 2019 to June 2021 were enrolled in the study, including 35 cases treated with ET-GA (ET-GA group) and 35 cases treated with conventional open thyroidectomy (COT group). The surgical treatment effect, cosmetic effect and the effect on neck function were compared between two groups. Neck function was evaluated by neck pain score, neck injury index and dysphagia index. Cosmetic effect was evaluated by cosmetic effect satisfaction score. In the ET-GA group, all unilateral thyroid lobectomy with central neck dissection were successfully completed, and no case was converted to open surgery. The number of central lymph nodes dissected in the ET-GA was not statistically different from that in the COT group (>0.05), but the operation time was longer than that of the COT group (<0.01). In the ET-GA group, 2 cases (5.7%) had transient vocal cord paralysis and 1 case (2.9%) had postoperative bleeding. In the COT group, 1 case (2.9%) had transient vocal cord paralysis, no postoperative bleeding. There was no significant difference in the complication rate between two groups (>0.05). At and postoperatively, there was no significant difference in neck pain score and neck injury index between two groups (both >0.05); dysphagia index was lower in ET-GA group, but the difference was not statistically significant (>0.05). The cosmetic effect satisfaction score of ET-GA group was higher than that in the COT group at postoperatively (4.3±0.6 vs.1.0, <0.01). ET-GA has the same efficacy and safety as conventional open thyroidectomy in the treatment of low-risk PTC, and it improves the satisfaction of postoperative cosmetics.

ABSTRACT

BACKGROUND: The single vitrified-warmed blastocyst transfer (SVBT) cycle has been increasingly utilized for assisted reproductive technology. Women of advanced maternal age (AMA) comprise a significant portion of patients who have undergone ‘freeze-all’ cycles. This study investigated the association between the post-warming extended culture duration and pregnancy outcomes in patients of AMA.

METHODS: This retrospective cohort study analyzed the outcomes of 697 SVBT cycles between January 2016 and December 2017. The cycles were divided into 3 groups based on the age of the female partners: group I: < 35 years (n = 407), group II: 35-37 years (n = 176); and group III, 38-40 years (n = 114). Data are shown as the mean ± standard error of the mean. Data were analyzed using one-way ANOVA followed by Duncan’s multiple range test. Statistical significance was set at P < 0.001.

RESULTS: The blastocyst rate, clinical pregnancy rate, and live birth rate (LBR) was significantly lower in the AMA groups. However, there were no significant differences in LBR in the transfer between the AMA and younger groups according to blastocyst morphology and post-warming extended culture duration.

CONCLUSION: Post-warming extended culture of blastocysts is not harmful to patients of AMA. It could be a useful parameter in clinical counseling and decision making for fertility treatments.

ABSTRACT

BACKGROUND: It is quite difficult to distinguish retractile testis from gliding testis, which requires different treatment planning in the clinic setting. We evaluated practice patterns of urologists in Korea regarding the diagnosis and management of retractile and gliding testes.

METHODS: We mailed or e-mailed self-completion questionnaires consisting of 20 items to 106 urologists practicing in Korean hospitals concerning the diagnosis and treatment of cryptorchidism. We collected and analyzed the responses statistically.

RESULTS: Responses were received from 62 urologists. The response rate was 58.5%. Thirty-seven urologists (59.7%) actually felt they had difficulty in distinguishing retractile testis from gliding testis in the clinic setting. This rate was higher for non-pediatric urologists (78.1%) than for pediatric urologists (40.0%) (P = 0.006). In cases of infant retractile testis, only five urologists (8.1%) said that they would perform orchiopexy immediately, with 54 (87.1%) urologists saying they would do follow-up. In cases of preschool-age children with retractile testis, 17 urologists (27.4%) said that they would perform orchiopexy immediately with 41 (66.1%) urologists saying they would do follow-up. In cases of infant gliding testis, 37 urologists (59.7%) said that they would perform orchiopexy immediately with 24 (38.7%) urologists saying they would do a follow-up.

CONCLUSION: More than half (59.7%) of Korean urologists revealed it challenging to distinguish retractile testis and gliding testis in the clinical setting. The more it was difficult to diagnose retractile testis with certainty, the more frequent surgical correction was chosen for treatment. Therefore, it is essential to prevent unnecessary surgical treatment by establishing a practical guideline.
