Evidence of peripheral olfactory impairment in the domestic silkworms: insight from the comparative transcriptome and population genetics.

BACKGROUND: The insect olfactory system is a highly specific and sensitive chemical detector, which plays important roles in feeding, mating and finding an appropriate oviposition site. The ecological niche of Bombyx mori has changed greatly since domestication from B. mandarina, and its olfactory response to environmental odorants clearly decreased. However, the mechanisms that result in the olfactory impairment are largely unknown. RESULTS: The antennal transcriptomes were compared between the domestic and wild silkworms. Comparison of the same sex between the domestic and wild silkworms revealed 1410 and 1173 differentially expressed genes (DEGs) in males and females, respectively. To understand the olfactory impairment, we mainly focused on the olfactory-related genes. In total, 30 olfactory genes and 19 odorant-degrading enzymes (ODEs) showed differential expression in the two comparisons, in which 19 and 14 were down-regulated in the domestic silkworm, respectively. Based on population genomic data, the down-regulated odorant receptors (ORs) showed a higher ratio of unique non-synonymous polymorphisms to synonymous polymorphisms (N/S ratio) in the domestic populations than that in the wild silkworms. Furthermore, one deleterious mutation was found in OR30 of the domestic population, which was located in transmembrane helix 6 (TM6). CONCLUSIONS: Our results suggested that down-regulation of the olfactory-related genes and relaxed selection might be the major reasons for olfactory impairment of the domestic silkworm reared completely indoor environment. Reversely, wild silkworm may increase expression and remove deleterious polymorphisms of olfactory-related genes to retain sensitive olfaction.

Is extra-pleura Nuss procedure more secure and effective?

PURPOSE: To compare total extra-pleura Nuss procedure with classical Nuss, and evaluate the efficacies and safety of thoracoscopic total extra-pleural approach of Nuss procedure for correction of pectus excavatum in children. METHODS: We managed 69 patients with pectus excavatum from July 2006 to October 2012. Of the 69 patients, 40 underwent thoracoscopic total extra-pleural approach of Nuss (group A), and 29 underwent classical Nuss procedure (group B). In group A, there were 29 boys and 11 girls, and the mean age was 6.4 (ranged from 3.5 to 14.5). Under thoracoscopic guidance, an extra-pleural tunnel was created using a blunt dissector via a right thoracic incision. A steel bar was inserted in the entirely extra-pleural tunnel. The bar was turned and fixed as in standard Nuss procedure. In group B, there were 20 boys and 9 girls, and the mean age was 5.9 (ranged from 4 to 11) years. Under thoracoscopic guidance, a blunt dissector was inserted into pleura cavity directly via a right thoracic incision. It was a standard Nuss procedure. RESULTS: The operations were completed successfully in all patients. None of the children developed pneumothorax or injuries to the pericardium, heart or lungs. The operating time was 42.0 ± 5.3 and 43.4 ± 6.0 min in group A and B, respectively, and the difference was not significant (p = 0.306). Compared to group B, the postoperative hospital stay of group A was shorter (4.0 ± 1.1 vs 5.2 ± 1.2 days, p = 0.001). The outcomes of both groups were similar (97.5% in group A vs 93.8% in group B, p = 0.377) but pain time was shorter, and time of taking painkiller was less than those of group B (2.6 ± 0.8 vs 4.1 ± 1.0 days, p = 0.001; 1.1 ± 0.6 vs 1.8 ± 0.9 time, p = 0.008). No patients in group A developed subcutaneous emphysema or pleural irritation, while 5 patients in group B showed the symptoms (p = 0.004). All patients were followed-up for 4-30 months (mean 20.2). During the follow-up, none of the children had pulmonary infection or dislocation of the steel board or fixation instruments before the bar was removed. 69 patients removed their bar after a 24-month period on average. According to Nuss' postoperative assessment criteria, one patient in group B was fair. The other patients were all excellent or good. CONCLUSIONS: Extra-pleura Nuss procedure under thoracoscopic guidance is a safe and less traumatic procedure for the correction of pectus excavatum. It is not only superior in postoperative recovery and pleural cavity protection, but also results in fewer complications than the intrapleural procedures.

Preliminary screening of 44 plant extracts for anti-tyrosinase and antioxidant activities.

In order to find new tyrosinase inhibitors and antioxidant materials, we investigated 44 plants, which were evaluated for the anti-tyrosinase and antioxidant activities. The mushroom tyrosinase inhibition assay and 2, 2-Diphenyl-1- picrylhydrazyl (DPPH) radical scavenging assay were conducted to evaluate these activities. Among all tested plant extracts, Morus alba L. (positive control), Rhodiola crenulata (Hook. f. et Thoms.) H. Ohba, Momordica charantia L., Cuminum cyminum L. et al. exhibit higher tyrosinase inhibition. Rhodiola crenulata (Hook. f. et Thoms.) H. Ohba, Rosa rugosa Thunb. and Eugenia caryophyllata Thunb. perform the highest antioxidant activity, similar to vitamin C (the positive control). A low positive correlation is found in the DPPH radical scavenging and tyrosinase inhibition assay. Considering these factors, the extracts of Rhodiola crenulata (Hook. f. et Thoms.) H. Ohba, Alpinia officinarum Hance and Zanthoxylum bungeanum Maxim. exhibit high anti-tyrosinase and antioxidant activities and could be used in the cosmetic industry. Further studies are warranted to characterize the compounds responsible for the anti-tyrosinase and antioxidant properties of these plant extracts.

How can industrial intelligence change the employment structure of the floating population?

As the wave of industrial intelligence (AI) swept, the demographic dividend era in the Chinese labor market continued to decrease. This study aimed to explore how AI reshaped the labor employment structure of the floating population. Additionally, it clarified the internal mechanism of AI on the employment structure of the floating population based on the existing AI model and the theoretical model of AI technology. At the same time, the workforce was divided into high-, medium-, and low-skilled groups according to education level. Empirical analysis was conducted using relevant data from 31 Chinese provinces spanning from 2012 to 2018. The aim was to test the impact of AI technology on the employment of different types of floating populations. The results indicated that: (1) industrial robots impacted heterogeneous skilled floating population labor by bipolar promotion and central substitution. (2) The application of industrial robots had a promotion effect on unfinished school and primary school groups, a substitution effect on middle school, high school/technical secondary school, and college specialties, and a promotion effect on college undergraduate and graduate students. (3) Distinguish employment status, industrial robot application had a significant negative impact on low-skilled employees and significant positive effects on high-skilled employers. Hence, it was recommended to put forward corresponding policy suggestions to address this issue.

Accuracy of death risk prediction models for acute coronary syndrome patients: a systematic review and meta-analysis.

INTRODUCTION: This study systematically evaluates the accuracy of several death risk prediction models for patients with acute coronary syndrome (ACS) through evidence-based methods. We identify the most accurate and effective ACS death risk prediction model and provide an evidence-based basis for clinical healthcare personnel to evaluate their choice of death risk prediction model for ACS patients. EVIDENCE ACQUISITION: An evidence-based approach was used to study the current death risk prediction model for ACS. First, a literature search was carried out using computer-based and manual searching. The literature databases searched include Cochrane Library, MEDLINE, EMBASE, PubMed, Web of Science, WanFang Data, CNKI, VPCS, and SinoMed. The search period was limited to 2009 to 2022. Screening, quality evaluation and data extraction were carried out for the included articles. The PROBAST was used to conduct a migration risk assessment. RevMan 5.3 and Meta-DiSc 1.4 were used in combination to determine the model effect sizes. A descriptive analysis was conducted for the data that could not be meta-analyzed. EVIDENCE SYNTHESIS: A total of 8277 articles were initially included in this study. After screening, 25 articles were finally included, involving 11 different risk prediction models. A total of 306,390 patients with ACS were included of which 158,080 (51.6%) were male and 147,793 (48.4%) were female. The patients stemmed from 11 different countries (e.g., China, the USA, Spain, the UK, etc.). The total number of deaths was 23,601. The sensitivity of the GRACE risk prediction model was 0.78, with a specificity of 0.76 and an AUC value of 0.86. The sensitivity of the CAMI risk prediction model was 0.78, with a specificity of 0.70 and an AUC value of 0.85. The sensitivity of the TIMI risk prediction model was 0.51, with a specificity of 0.81, and an AUC value of 0.64. The sensitivity of the REMS risk prediction model was 0.78, with a specificity of 0.46 and an AUC value of 0.41. Eight different risk prediction models (EPICOR, CRUSADE, SAMI, GWTG, LNS, SYNTAX II, APACHE II) that could not be combined with the effect size were also included, with sensitivities ranging from 0.77-0.95, specificities ranging from 0.22-0.99, and AUC values ranging from 0.71-0.92. CONCLUSIONS: The GRACE and CAMI risk prediction models demonstrate good accuracy for evaluating the death risk of ACS patients. The accuracy of the TIMI risk prediction model is similar to that of the REMS risk prediction model. The APACHE II, SYNTAX II, EPICOR, and CAMI risk prediction models also show good accuracy for estimating the risk of death in ACS patients, although further validation is needed due to limited evidence. For improved predictive accuracy and to help advance medical interventions, the author recommends that clinical medical staff use the GRACE model to predict the death risk of ACS patients.

Microglia contribute to neuronal synchrony despite endogenous ATP-related phenotypic transformation in acute mouse brain slices.

Acute brain slices represent a workhorse model for studying the central nervous system (CNS) from nanoscale events to complex circuits. While slice preparation inherently involves tissue damage, it is unclear how microglia, the main immune cells and damage sensors of the CNS react to this injury and shape neuronal activity ex vivo. To this end, we investigated microglial phenotypes and contribution to network organization and functioning in acute brain slices. We reveal time-dependent microglial phenotype changes influenced by complex extracellular ATP dynamics through P2Y12R and CX3CR1 signalling, which is sustained for hours in ex vivo mouse brain slices. Downregulation of P2Y12R and changes of microglia-neuron interactions occur in line with alterations in the number of excitatory and inhibitory synapses over time. Importantly, functional microglia modulate synapse sprouting, while microglial dysfunction results in markedly impaired ripple activity both ex vivo and in vivo. Collectively, our data suggest that microglia are modulators of complex neuronal networks with important roles to maintain neuronal network integrity and activity. We suggest that slice preparation can be used to model time-dependent changes of microglia-neuron interactions to reveal how microglia shape neuronal circuits in physiological and pathological conditions.

A 1.1 Mb duplication CNV on chromosome 17 contributes to skeletal muscle development in Boer goats.

The Boer goat is one of the top meat breeds in modern animal husbandry and has attracted widespread attention for its unique growth performance. However, the genetic basis of muscle development in the Boer goat remains obscure. In this study, we identified specific structural variants in the Boer goat based on genome-wide selection signals and analyzed the basis of the molecular heredity of related candidate genes in muscle development. A total of 9 959 autosomal copy number variations (CNVs) were identified through selection signal analysis in 127 goat genomes. Specifically, we confirmed that the highest signal CNV (HSV) was a chromosomal arrangement containing an approximately 1.11 Mb (CHIR17: 60062304-61171840 bp) duplicated fragment inserted in reverse orientation and a 5 362 bp deleted region (CHIR17:60145940-60151302 bp) with overlapping genes (e.g., ARHGAP10, NR3C2, EDNRA, PRMT9, and TMEM184C). The homozygous duplicated HSV genotype (+/+) was found in 96% of Boer goats but was not detected in Eurasian goats and was only detected in 4% of indigenous African goats. The expression network of three candidate genes ( ARHGAP10, NR3C2, and EDNRA) regulating dose transcription was constructed by RNA sequencing. Results indicated that these genes were involved in the proliferation and differentiation of skeletal muscle satellite cells (SMSCs) and their overexpression significantly increased the expression of SAA3. The HSV of the Boer goat contributed to superior skeletal muscle growth via the dose effects of overlapping genes.

FABP4 in Paneth cells regulates antimicrobial protein expression to reprogram gut microbiota.

Antimicrobial proteins possess a broad spectrum of bactericidal activity and play an important role in shaping the composition of gut microbiota, which is related to multiple diseases such as metabolic syndrome. However, it is incompletely known for the regulation of defensin expression in the gut Paneth cells. Here, we found that FABP4 in the Paneth cells of gut epithelial cells and organoids can downregulate the expression of defensins. FABP4fl/flpvillinCreT mice were highly resistance to Salmonella Typhimurium (S.T) infection and had increased bactericidal ability to pathogens. The FABP4-mediated downregulation of defensins is through degrading PPARγ after K48 ubiquitination. We also demonstrate that high-fat diet (HFD)-mediated downregulation of defensins is through inducing a robust FABP4 in Paneth cells. Firmicutes/Bacteroidetes (F/B) ratio in FABP4fl/flpvillinCreT mice is lower than control mice, which is opposite to that in mice fed HFD, indicating that FABP4 in the Paneth cells could reprogram gut microbiota. Interestingly, FABP4-mediated downregulation of defensins in Paneth cells not only happens in mice but also in human. A better understanding of the regulation of defensins, especially HFD-mediated downregulation of defensin in Paneth cells will provide insights into factor(s) underlying modern diseases.Abbreviations: FABP4: Fatty acid binding protein 4; S.

Discovery of tumor immune infiltration-related snoRNAs for predicting tumor immune microenvironment status and prognosis in lung adenocarcinoma.

Lung adenocarcinoma (LUAD) has a high mortality rate and is difficult to diagnose and treat in its early stage. Previous studies have demonstrated that small nucleolar RNAs (snoRNAs) play a critical role in tumor immune infiltration and the development of a variety of solid tumors. However, there have been no studies on the correlation between tumor-infiltrating immune-related snoRNAs (TIISRs) and LUAD. In this study, we filtered six immune-related snoRNAs based on the tissue specificity index (TSI) and expression profile of all snoRNAs between all LUAD cell lines from the Cancer Cell Line Encyclopedia and 21 types of immune cells from the Gene Expression Omnibus database. Further, we performed real-time quantitative polymerase chain reaction (RT-qPCR) to validate the expression status of these snoRNAs on peripheral blood mononuclear cells (PBMCs) and lung cancer cell lines. Next, we developed a TIISR signature based on the expression profiles of snoRNAs from 479 LUAD patients filtered by the random survival forest algorithm. We then analyzed the value of this TIISR signature (TIISR risk score) for assessing tumor immune infiltration, immune checkpoint inhibitor (ICI) treatment response, and the prognosis of LUAD between groups with high and low TIISR risk score. Further, we found that the TIISR risk score groups showed significant differences in biological characteristics and that the risk score could be used to assess the level of tumor immune cell infiltration, thereby predicting prognosis and responsiveness to immunotherapy in LUAD patients.

Efficacy of vaginal probiotic capsules for recurrent bacterial vaginosis: a double-blind, randomized, placebo-controlled study.

OBJECTIVE: We assessed the effectiveness of vaginal probiotic capsules for recurrent bacterial vaginosis (BV) prevention. STUDY DESIGN: One hundred twenty healthy Chinese women with a history of recurrent BV were assigned randomly to daily vaginal prophylaxis with 1 capsule (Probaclac Vaginal; Nicar Laboratories, Inc, Blainville, Quebec, Canada) that contained 8 billion colony-forming units of Lactobacillus rhamnosus, L acidophilus, and Streptococcus thermophilus (n = 58 women) or 1 placebo capsule (n = 62 women) for 7 days on, 7 days off, and 7 days on. RESULTS: Probiotic prophylaxis resulted in lower recurrence rates for BV (15.8% [9/57 women] vs 45.0% [27/60 women]; P < .001) and Gardnerella vaginalis incidence through 2 months (3.5% [2/57 women] vs 18.3% [11/60 women]; P = .02). Between the 2- and 11-month follow-up period, women who received probiotics reported a lower incidence of BV and G vaginalis. Aside from vaginal discharge and malodor, no adverse events were reported in either study group. CONCLUSION: Short-term probiotic prophylaxis is well tolerated and reduces BV recurrence and G vaginalis risk through 11 months after treatment.

The preventive efficacy of methylcobalamin on rat peripheral neuropathy influenced by diabetes via neural IGF-1 levels.

We investigated the preventive efficacy of exogenous methylcobalamin on sciatic nerve IGF-1 expression down-regulation and peripheral nerve deficit under different conditions (hyperglycemia and duration) of experimental diabetes in rats. Hyperglycemia was induced with streptozotocin, and stratified by exogenous insulin into mild and severe conditions. Duration of diabetes was ranged from 2-12 weeks. A single dose of methylcobalamin was intramuscularly administrated. Three groups of rats were compared in this study: (i) control group (NC, n = 30); (ii) saline-treated control diabetic group (n = 30); and (iii) methylcobalamin-treated diabetic group (n = 30). The study demonstrated a progressive decrease of sciatic nerve IGF-1 mRNA and peptide contents, and peripheral nerve dysfunction in the saline-treated diabetics over 12 weeks in contrast to the normal control non-diabetics (P < 0.01-0.0025). The IGF-1 reduction was delayed, which was consistent with retardation in nerve velocity conduction and structural impairment, in the methylcobalamin-treated diabetics, especially with mild hyperglycemia and shorter duration as compared with the saline-treated diabetics (P < 0.05-0.01). No effect of methylcobalamin on blood glucose was shown in the treated groups. It is concluded that exogenous methylcobalamin delayed onset of diabetic peripheral neuropathy via up-regulation of neural IGF-1 gene expression, and a better neuroprotective effect could be achieved in the presence of good control of hyperglycemia, especially at early stage of diabetes.

[Influence of the interruption of arteria iliaca interna distal end on penile vascularity and erectile function in male renal transplant recipients].

OBJECTIVE: It is controversial whether unilateral interruption of the arteria iliaca interna distal end affects penile hemodynamics and erectile function. The purpose of this study was to prospectively evaluate this influence by detecting the blood flow of the penile artery before and after renal transplantation. METHODS: Thirty-three patients with chronic renal failure (CRF) on maintenance hemodialysis (MHD) received renal transplantation, the grafts revascularized by end-to-end anastomosis to the right internal iliac artery. Six months before and after the surgery, we obtained the IIEF scores of the patients, recorded their penile blood flow on color Doppler ultrasonography and the levels of serum creatinine, hemoglobin and serum cholesterol, and analyzed post-transplantation immunosuppressive medication. RESULTS: The patients ranged in age from 21 to 55 years, of whom 36% had erectile dysfunction (ED) during MHD, and 33% after renal transplantation. A total of 67% of the renal transplant recipients (RTR) complained of unchanged and 15% deteriorated ED, while 18% admitted improved erectile function. The patients showed a significantly stronger sexual desire after the transplantation than before it (6.2 +/- 1.6 vs 8.9 +/- 0.9, P < 0.01). There was a significant decrease in peak systolic velocity (PSV) in the cavernous arteries after transplantation as compared with pre-transplantation (P < 0.01). Penile arterial blood flow insufficiency was found in none of the RTRs. CONCLUSION: Unilateral interruption of the internal iliac artery decreases penile arterial blood flow, but not to such a degree as to result in ED. Unilateral interruption of the arteria iliaca interna distal end does not affect the erectile function of RTRs.

AMI, an Indazole Derivative, Improves Parkinson's Disease by Inhibiting Tau Phosphorylation.

Dopaminergic neuronal loss is the main pathological character of Parkinson's disease (PD). Abnormal tau hyperphosphorylation will lead to dopaminergic neuronal loss. An indazole derivative 6-amino-1-methyl-indazole (AMI) successfully synthesized to inhibit tau hyperphosphorylation may exert a neuroprotective effect. The in vitro study showed that AMI effectively increased cell viability and alleviated the apoptosis induced by MPP+ in SH-SY5Y cells. In addition, AMI treatment significantly decreased the expression of p-tau and upstream kinases GSK-3ß. In the MPTP-induced PD mice models, we found AMI apparently preserved dopaminergic neurons in the substantia nigra and improved the PD behavioral symptoms. Our results demonstrate that AMI exerts a neuroprotective effect by inhibiting tau hyperphosphorylation, representing a promising new candidate for PD treatment.

[Appropriate use of immunosuppressants after renal transplantation].

Kidney transplantation has become an important method in treating advanced renal failure. Immunosuppressants play a key tool in this progress. It is important to understand the goal, mechanism, and adverse effects of immunosuppressive therapy, so as to appropriately use these drugs in post-transplantation patients on a customized basis.

[Prevention and treatment of hypertension after renal transplantation].

Hypertension is a common complication after renal transplantation. Among post-transplantation patients died of cardiovascular diseases, about 41% have hypertension. Hypertension is an independent risk factor for kidney transplant failure. Post-transplantation hypertension can be caused by many factors, including the use of immunosuppressants. When the blood pressure exceeds 130/90 mmHg in a kidney transplant recipient, it is reasonable to provide active medical intervention. In summary, prevention and treatment of hypertension is important to prolong the survival of kidney transplant recipients.

[Clinical study of application of sirolimus with dose-reduced or discontinued cyclosporine A for prevention of acute rejection after kidney transplantation].

OBJECTIVE: To study the clinical efficacy, safety and feasibility of sirolimus (SRL) for preventing acute rejection of kidney transplantation. METHODS: Thirty patients with end-stage kidney dysfunction received kidney transplants from June 2004 to December 2004. There were 21 male and 9 female aged from 22 to 67 years old, with a mean of (46.3 +/- 10.0) years old. SRL was used in primary immunosuppression therapy to prevent acute rejection after surgery, and all of them were treated in combination with dose-reduced cyclosporine A (CsA) and steroid. CsA reduction began 3 months after the surgery, the weekly dose of CsA about 10 to 25 percent reduction until completely discontinued. During a 4-year follow-up period, the adverse events, acute rejection and infection were observed and recorded in detail. The graft function and other laboratory indicators were checked and analyzed. RESULTS: Of the 30 patients, 4 recipients died, patients survival rate was 86.7%. In other 26 cases, 25 recipients had good graft function, the average blood creatinine was (103.8 +/- 4.6) micromol/L at the end of 4(th) year and the incidence of acute rejection was 6.7% (2/30). The side effects included hyperlipidemia, proteinuria, delayed healing incision, lactate dehydrogenase increased and joint pain. CONCLUSION: The combination of sirolimus with dose-reduced CsA till completely discontinued and steroid to prevent acute rejection of kidney transplantation is safe and efficient.

Prevalence and influential factors of erectile dysfunction in male renal transplant recipients: a multiple center survey.

BACKGROUND: Renal transplants can improve the quality of life for recipients, but the quality of their sexual life might not be improved. This study was conducted to research the prevalence of erectile dysfunction (ED) and the influential factors in male renal transplant recipients (RTRs). METHODS: A cross-sectional survey was conducted in three renal transplantation centers. Structured questionnaires were administrated by trained interviewers to 824 male renal transplant patients, who had active sexual lives in the last 6 months. RESULTS: Complaints of ED were reported by 75.5% of the 809 RTRs (age range 19 - 75 years, mean age (45 +/- 10) years), whose questionnaires were completed. Mild, moderate and severe ED were reported at 53.6%, 8.3% and 13.6%, respectively. The mean age and the graft duration were significantly higher in male RTRs with ED compared to potent graft recipients (P = 0.00 and 0.04, respectively). The prevalence of ED increased with the increase in age. It was 60.7%, 65.8%, 75.2%, 87.5% and 92.2% in patients with age below 30 years, 31 - 40 years, 41 - 50 years, 51 - 60 years and over 60 years, respectively (P = 0.000). Moreover, the severity of ED increased with aging. The percentage of moderate and severe cases of ED increased from 6.7% in patients below 40 years to 28.9% in those over 40 years (P = 0.000). The prevalence of ED in the RTR who had no occupation was higher than in those who were holding a position (P = 0.001). The prevalence of ED decreased with the increase in the education level. The prevalence of ED was 94.3%, 86.4%, 74.0% and 67.8% in men with elementary school or lower, middle school, high school, and college or higher degrees, respectively (P = 0.000). Patients, whose distal end of arteria iliaca interna was interrupted and underwent iterative transplantation, worried transplanted kidney function was impacted by sexual life, and received cyclosporine (CsA)-based immunosuppressive regimens, were more likely to have ED (P = 0.000, 0.001, 0.000, 0.000, respectively). After Logistic regression analysis, only five factors, age, education level, interruption of arteria iliaca interna distal end, worrying transplanted kidney function impacted by sexual life and CsA-based immunosuppressive regimens sustained their significance. CONCLUSIONS: Renal transplant has varying effects on erectile function. ED is highly prevalent among RTRs and its influential factors are multiple. Age, education level, interruption of arteria iliaca interna distal end, worrying transplanted kidney function impacted by sexual life, CsA-based immunosuppressive regimens are the main influential factors of ED in male RTRs.

[Living related donor kidney transplantation: analysis of 117 cases].

OBJECTIVE: To summarize the clinical experience in living related donor kidney transplantation. METHODS: 117 patients with different nephropathies underwent transplantation of kidneys donated by their collateral relative in three generations. All donor kidneys were removed by open nephrectomy. Immunosuppressive protocols which consisting of cyclosporine A/tacrolimus, mycophenolate mofetil/azathioprine/rapamycin, and steroid were used in all patients as immunosuppressors. Follow-up was conducted for 1-44 months. RESULTS: Delayed graft function recovery occurred in 2 patients. Acute rejection episodes occurred in 18 patients, and the condition was reversed by high intravenous dose of methyl-prednisolone or polyclonal anti-T-cell antibodies. Follow-up showed that all the patients survived with normal kidney function, and the donors kept good kidney function with normal life quality. Hypertension was found in 2 donors and diabetes mellitus was found in 1 donor. CONCLUSION: Careful evaluation of both psychological and physical status of the donors and optimal physical status of recipients before operation are critical for successful kidney transplantation. Injury of graft kidney should be reduced and recipients should be treated with sufficient immunosuppressive regimen in early stage after transplantation.

Interpretation and review of Clinical Practice Guidelines for Management of Hypertension in China (2020 edition) and exploration of traditional Chinese medicine for antihypertensive treatment / 中国中药杂志

Hypertension is the most important risk factor for cardiovascular disease-related deaths among urban and rural residents, and it has become a significant global public health issue. In October 2022, the Clinical Practice Guidelines for the Management of Hypertension in China(hereinafter referred to as the Practice Guidelines) were jointly released by the National Cardiovascular Center and other academic organizations. The Practice Guidelines sparked extensive discussions as they clearly lowered the diagnostic criteria for hypertension, raised the blood pressure targets for elderly patients, and proposed changes in the timing of early medication intervention. While these adjustments have some international evidence-based support, there is still debate regarding the cardiovascular benefits of intensified blood pressure control based on the existing level of evidence. Furthermore, whether the series of new standards proposed in the Practice Guidelines are suitable for the Chinese population and whether the hypertension control level in primary care in China can adapt to the new diagnostic and treatment standards require further in-depth research. In contrast to the strict blood pressure control concept emphasized in the Practice Guidelines, traditional Chinese medicine(TCM) emphasizes the concept of comprehensive prevention and treatment and holistic therapy in the treatment of hypertension, including prehypertension, hypertension, and target organ damage. In recent years, based on abundant clinical trial research and high-quality evidence-based support, the advantages of TCM in treating hypertension have gradually emerged. Previous studies by this research team have found that the pathogenesis of hypertension includes three major types: fire syndrome, fluid retention syndrome, and deficiency syndrome. TCM treatment of hypertension features stable blood pressure reduction, gentle blood pressure lowering, and long-lasting effects. In addition to blood pressure reduction, it also has effects such as reversing risk factors and protecting target organ damage. It demonstrates the characteristics of multiple targets, multiple components, and comprehensive regulation, and can be applied throughout the entire process of prevention and treatment, including prehypertension, hypertension, and target organ damage in the early, middle, and late stages of hypertension. Therefore, it has certain clinical application prospects.

Scoping review of acupuncture-moxibustion treatment for non-specific low back pain / 中国中药杂志

This study systematically searched and sorted out randomized controlled trial(RCT) of acupuncture-moxibustion treatment for non-specific low back pain by scoping review, so as to demonstrate the current state of the research evidence and provide a reference point for future clinical research and healthcare decision-making. Eight commonly used Chinese and English databases were searched, and the search time was from the establishment of the databases to July 7, 2023, so as to analyze the characteristics of the current status of the current research through visualization methods. A total of 50 studies were included, including 23 studies in Chinese and 27 studies in English. The overall number of studies showed an increasing trend. The percentage of studies published in Chinese non-core journals was 42.0%. The disease subtypes of interest were mainly chronic non-specific low back pain, accounting for 68.0% of the studies. The sample sizes of the studies were mainly concentrated in the range of 50-100 cases. A total of 15 types of interventions were categorized, with acupuncture interventions being the most studied. Duration of treatment did not exceed one month in 80.0% of the studies. Only 8.0% of the studies used minimal clinical important difference(MCID) as a basis for judgment. The follow-up period was set within 3 months in 28.0% of the studies, and 82.0% of the studies concluded that acupuncture-moxibustion was effective in the treatment of non-specific lower back pain. Adverse events were reported in 20.0% of the studies. The risk of bias in the included studies was dominated by low risk of bias and uncertain risk of bias, with fewer studies focusing on high risks of bias. In most of the studies, acupuncture-moxibustion was significantly more effective than the control group. The research on acupuncture-moxibustion treatment for non-specific low back pain is developing rapidly, but there are still insufficient studies on psychological state, safety, and other indicators, and there are still some studies with uncertain risks of bias, which is not conducive to the generalization and application of the findings. Therefore, future studies should improve and refine these shortcomings.
