Objective:To understand the epidemiology of rubella and the genetic characteristics of the virus circulating during the period 2021-2022, providing basic scientific data for rubella prevention and control in China.Methods:National rubella incidence data for the period 2021-2022 were obtained from the Infectious Disease Surveillance System module and the Surveillance Report Management module of the China′s Disease Prevention and Control Information System. Positive rubella virus(RuV)isolates were obtained from the National Measles/Rubella Laboratory Network. Two nucleotide (nt) fragments [F1-480 (8 633-9 112 nt) and F2-633 (8 945-9 577 nt)] located in the E1 gene were amplified and determined by reverse transcription polymerase chain reaction (RT-PCR), and the target gene (E1-739) was obtained after collating and splicing. The sequences obtained in this study were used to construct a phylogenetic tree with the reported reference strains for genotype and lineage identification. Additionally, the phylogenetic analysis was performed to assess their genetic relatedness of RuV strains prevalent in China during 2018-2020 from GenBank database.Results:In 2021-2022, the rubella incidence in China was 0.06/100, 000 (2021: 840 cases; 2022: 784 cases), with cases primarily concentrated in the western and southern provinces. Age distribution analysis showed that rubella cases in 2021-2022 was mainly in children under 5 years of age (2021: 34.17%, 287/840; 2022: 42.09%, 330/784), with the highest proportion in children aged 0-2 years. Further analysis of the immunization history of cases revealed that in the 8-23 months age group, a significant proportion of cases had received only one dose of rubella containing vaccine (RCV); cases in the 2-14 years age group were mainly among children who had received two or more doses of RCV; however, cases over 15 years of age were primarily found in individuals who had not received RCV or had unknown immunization history. National virological surveillance data showed that totally 22 RuV virus isolates were obtained, from 6 provinces in China during 2021-2022, which belonged to lineage 1E-L2 (11 strains) and 2B-L2c (11 strains). And these viruses displayed high genetic homology with RuV prevalent from 2018 to 2020.Conclusions:The incidence of rubella in China was maintained at a low level during 2021-2022, and the prevalent RuV strains were lineage 1E-L2 and 2B-L2c.

Renal interstitial fibrosis (RIF) is the main pathological feature of chronic kidney disease caused by a variety of factors. "Kidney deficiency and blood stasis in collateral, miniature mass of renal collateral" is the main pathogenesis of RIF. The deficiency of healthy Qi will influence the kidney Qi, resulting in kidney deficiency and unsmooth qi transformation. As a result, phlegm, heat, stasis, toxin and other excess pathogens block the kidney collaterals, forming miniature masses. The masses accumulate in the renal collaterals, finally leading to RIF. Autophagy is a key process that keeps your body's cells in proper balance by taking aged or damaged components in a cell and recycling them. It is involved in the occurrence and development of RIF. The metabolism of excess pathogens such as phlegm, heat, stasis, and toxin in vivo is related to the degradation and reabsorption of autophagy. Autophagy is a way to eliminate phlegm, heat, stasis, toxin and other excess pathogens. Autophagy dysfunction will cause the accumulation of phlegm, heat, blood stasis, toxin and other excess pathogens, further the stasis of the kidney collaterals, miniature mass in kidney, and finally RIF. Kidney deficiency and blood stasis in collateral are the root cause of autophagy dysfunction, and the miniature mass of renal collateral is the manifestation of autophagy dysfunction. Autophagy dysfunction and miniature mass of renal collateral have the same pathological evolution. In this paper, based on the pathogenesis of "kidney deficiency and blood stasis in collateral, miniature mass of renal collateral" of RIF and RIF-autophagy relationship, this paper discusses the "kidney deficiency and blood stasis in collateral-autophagy dysfunction-miniature mass of renal collateral" relationship in RIF and comprehensively interprets the scientific connotation of the pathogenesis of "kidney deficiency and blood stasis in collateral, miniature mass of renal collateral", which is expected to lay a basis for explaining the role of autophagy in TCM theory and for the treatment of RIF and research on the mechanism.

Renal interstitial fibrosis(RIF)is a common pathway for the progression of chronic kidney disease to renal failure,and its pathogenesis is mainly related to renal inflammatory damage,oxidative stress,apoptosis,and excessive extracellular matrix(ECM) deposition. Transforming growth factor-β1(TGF-β1) signaling pathway,mammalian target of rapamycin(mTOR) signaling pathway and other signaling pathways mediate the occurrence and development of RIF. Because of the complicated mechanism of RIF,there have been no specific prevention and treatment measures in clinical practice. Autophagy is a non-damaging response produced by eukaryotic cells. It maintains the balance of tissue homeostasis through degradation and reabsorption. At present, Chinese medicine has achieved desirable clinical effects with its unique advantages of multiple components,multiple effects,and multiple targets in the treatment of chronic kidney disease to delay the process of RIF. Scholars have found that autophagy is consistent with the Yin-Yang theory and the theory of abdominal mass in traditional Chinese medicine (TCM) to a certain extent,and it is involved in many aspects of RIF. The progression of RIF is closely related to autophagy. The targeted therapy of RIF by intervention in autophagy has become the frontier of research. However,little is known about the role of autophagy in RIF and the regulation of autophagy by Chinese medicine in the treatment of RIF. Therefore,it is necessary to further elucidate the relationship between autophagy and RIF in order to clarify the mechanism of autophagy in RIF and the mechanism of Chinese medicine regulating autophagy in targeted therapy of RIF. This article focused on the correlation between autophagy and RIF based on TCM theory,and systematically summarized the role of autophagy in RIF and the intervention of Chinese medicine by combining the effects of autophagy on inflammation damage,oxidative stress,apoptosis,and excessive ECM deposition in RIF, and the regulation mechanism of autophagy in TGF-β1 and mTOR signaling pathways in RIF. This study was expected to provide a certain reference for the clinical treatment of RIF and the development of new drugs.

Chronic renal failure (CRF), a common outcome of various chronic kidney diseases, is characterized by retention of metabolites and toxins, water-electrolyte imbalance, acid-base disturbance, and various symptoms in diverse systems. The incidence and progression of this disease are influenced by many factors, particularly the change of intestinal flora. Previous research shows that the intestinal flora interacts with CRF. For CRF patients, the metabolic waste fails to be cleared in time due to the gradual decline of renal function and thus accumulates in vivo. Moreover, CRF changes the composition of intestinal flora, damages intestinal barrier, and accelerates the synthesis of intestinal uremic toxins and the accumulation in blood. As a result, the renal injury is aggravated. The imbalance of intestinal flora can induce acute kidney injury, increase cardiovascular complications, stimulate immune inflammatory responses, and thus aggravate the progression of CRF. Microbiota-targeted therapy for CRF has become the research focus. According to traditional Chinese medicine, kidney disease is related to the intestine and kidney disease should be treated from the intestine. Spleen and kidney are in the closest relationship with the pathogenesis of CRF and the intestinal flora. Chinese medicine, which features multiple targets, multiple effects, and multiple components, acts on the "gut-kidney axis". It is thus superior in the clinical treatment of CRF and the regulation of intestinal flora. To be specific, it intervenes in intestinal flora to delay the process of CRF. In this paper, based on the correlation of traditional Chinese medicine theory with intestinal flora and CRF, this paper reviewed the interaction between intestinal flora and CRF and traditional Chinese medicine intervention in the intestinal flora for the treatment of CRF, which is expected to serve as a reference for the clinical treatment of this disease and the drug development.

Objective:To evaluate the effect of propofol anesthesia on autophagy in hippocampal neurons of newborn rats.Methods:Thirty-nine healthy Sprague-Dawley rats, aged 7 days, weighing 10-12 g, were divided into 3 groups ( n=13 each) using a random number table method: control group (group C), fat emulsion group (group F) and propofol group (group P). Normal saline 8 ml/kg was intraperitoneally injected for 5 consecutive days in group C. Medium-/long-chain fatty emulsion injection 8 ml/kg was intraperitoneally injected for 5 consecutive days in group F. Medium-/long-chain propofol injection 80 mg/kg was intraperitoneally injected for 5 consecutive days in group P. Five rats were sacrificed on 1st day after the end of propofol anesthesia, and hippocampal tissues were taken for determination of the expression of microtubule-associated protein 1 light chain 3B (LC3B) and Beclin-1 (by Western blot). The remaining rats in each group underwent the Morris water maze test on 19th day after the end of propofol anesthesia (30 days after birth), and the escape latency, percentage of time of staying at the target quadrant and the number of crossing the original platform were recorded. Results:Compared with group C, no significant change was found in the expression of hippocampal LC3B and Beclin-1, escape latency, percentage of time of staying at the target quadrant, and the number of crossing the original platform in group F ( P>0.05), and the expression of hippocampal LC3B and Beclin-1 was significantly up-regulated, the escape latency was prolonged, percentage of time of staying at the target quadrant was decreased, and the number of crossing the original platform was decreased in group P ( P<0.05 or 0.01). Conclusion:The mechanism by which propofol anesthesia causes long-term cognitive dysfunction may be related to promoting autophagy in hippocampal neurons of newborn rats.

Objective:To explore the clinical value of "hydration therapy" in the treatment of severe acute paraquat poisoning (APP).Methods:A prospective historical control observation was conducted. Fifty-eight patients with severe APP admitted to Shouguang People's Hospital Affiliated to Weifang Medical College from February 2014 to June 2019 were enrolled. Twenty-six patients admitted before May 10th, 2016 were enrolled in the standard treatment group. After being admitted to intensive care unit (ICU) from the department of emergency, patients in the standard treatment group were immediately given standard treatment such as repeated gastric lavage, catharsis, adsorption of poison by activated carbon or montmorillonite powder, drug treatment and blood purification. From May 10th, 2016, 32 patients were enrolled in the intensive treatment group. On the basis of standard treatment, "hydration therapy" was carried out, that was, 0.9% NaCl and/or 5% glucose injection were used for continuous intravenous infusion throughout the day, so as to ensure that the total amount of fluid infusion per day reached 200 mL/kg within 48-72 hours after ICU admission. At the same time, furosemide was used to strengthen diuresis to ensure the balance of water and electrolyte. If heart failure or acute pulmonary interstitial edema occurred during the treatment, "hydration therapy" should be stopped immediately. Six months after treatment, all patients were followed up. The patients with normal activity, no complaints of discomfort and no damage of heart, lung, liver, kidney and other organs were regarded as cured. The therapeutic effect of "hydration therapy" was evaluated.Results:There was no significant difference in gender, age, dosage or time from taking poison to ICU between the two groups. In the intensive treatment group, 32 patients did not appear heart failure during continuous rehydration treatment. Follow-up after 6 months showed that the overall cure rate in the intensive treatment group was significantly higher than that in the standard treatment group [59.4% (19/32) vs. 19.2% (5/26), P < 0.05]. In the 6-month follow-up, there was no significant difference in age or time from taking poison to ICU between the two groups, but the dosage in the intensive treatment group was significantly higher than that in the standard treatment group (mL: 54.06±26.03 vs. 23.00±4.47, P < 0.05). After 6 months of follow-up, chest CT showed that the lesions of pulmonary fibrosis of cured patients in both group gradually reduced with time, not completely progressive and irreversible. Conclusion:"Hydration therapy" with intensive diuresis can significantly improve the rescue success rate of patients with severe APP.
