ABSTRACT
Diabetic kidney disease （DKD） is characterized by the hyperfiltration and albuminuria in the early phase which are followed by progressive renal function decline， renal tubular epithelial cell hypertrophy， and tubulointerstitial fibrosis. Thus， it is one of the leading causes of chronic kidney diseases. The currently available therapies mainly aim to control the primary diseases and reduce the risk of kidney injury. Based on syndrome differentiation， traditional Chinese medicine （TCM） relieves the symptoms by excreting water and alleviating edema and eliminates the root cause by tonifying deficiency and supplementing the original Qi， thereby showing therapeutic effect and delaying the progression of DKD. It excels in comprehensively regulating the constitution of patients with little side effects. Among the Zang-fu organs， kidney takes the second place in the content of mitochondria which participate in the metabolism of water and fluid and are the foundation of kidney Yin and kidney Yang. Mitochondria are energy producers within a cell， which carry out cellular respiration， produce reactive oxygen species， and generate adenosine triphosphate by oxidative phosphorylation. Mitochondrial quality control （MQC） is an effective way to maintain mitochondrial dynamic balance， whose imbalances， such as mitochondrial oxidative stress， mitophagy， mitochondrial dynamic changes， and abnormal calcium regulation， are related to the occurrence and development of DKD. It is generally believed that the destruction of mitochondrial structure in the case of metabolic disorder is the main cause of the disease. In recent years， TCM has attracted the attention of both Chinese and foreign researchers for the unique advantages of treating both symptoms and root cause at the same time and multi-target synergy in the treatment of DKD. However， the specific mechanism is still unclear. It has been frequently verified that mitochondria may be one of the targets of TCM in the treatment of DKD. At the moment， no review on the treatment of DKD by TCM through the intervention of MQC is available. Therefore， this paper aims to summarize the research on TCM treatment of DKD by regulating MQC in the past 10 years， which is expected to provide a new direction for the treatment of DKD by TCM.
ABSTRACT
Objective To investigate the distribution of traditional Chinese medicine (TCM) syndrome types and elements in liver cirrhosis patients with dysplastic nodules (DN), and to provide a basis for exploring the connotation and pattern of TCM syndrome types of DN in liver cirrhosis. Methods A total of 138 patients who attended The First Affiliated Hospital of Henan University of Chinese Medicine from March 2013 to January 2021 and were diagnosed with liver cirrhosis and DN were enrolled. General data such as age of onset and sex were collected, as well as the data on etiology, TCM syndrome types, and Child-Pugh class for liver function, and the distribution characteristics of TCM syndrome types and elements were summarized. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results The liver and the spleen were the main syndrome elements of disease location in liver cirrhosis patients with DN, accounting for 97.83% and 94.93%, respectively, followed by the kidney (23.91%); Qi deficiency and Qi stagnation were the main syndrome elements reflecting the nature of disease, accounting for 73.91% and 58.70%, respectively, followed by dampness (34.78%). The main TCM syndrome types included stagnation of liver Qi and spleen deficiency, damp-heat internal excess syndrome, blood stasis and toxin accumulation syndrome, and water-dampness retention syndrome, among which stagnation of liver Qi and spleen deficiency was more common and accounted for 58.70% ( P 0.05). There was a significant difference in Child-Pugh class between the liver cirrhosis DN patients with different TCM syndrome types ( χ 2 =34.320, P < 0.05), and Child-Pugh class A was more common in the patients with stagnation of liver Qi and spleen deficiency (59.8%), while Child-Pugh class C was more common in the patients with damp-heat internal excess syndrome (39.1%). Conclusion This article summarizes the distribution characteristics of common TCM syndrome types and elements of DN in liver cirrhosis, which provides a reference for the syndrome differentiation-based TCM treatment of DN in liver cirrhosis.

Conclusion:Laparoscopic surgery after short-course radiotherapy followed by sequential chemotherapy combined with immunotherapy for locally advanced rectal cancer is safe and feasible, with satisfied short-term efficacy.
ABSTRACT
Objective:To explore the mechanism of modified Xiaoyao Powder on inflammatory response of rats with syndrome of stagnation of liver qi and spleen deficiency of experimental autoimmune thyroiditis (EAT) from the perspective of differentiation of microrna 326 (miR326) regulating Th17 cell.Methods:48 rats were randomly divided into normal group (12 rats) and model group (36 rats) respectively and they were immunized twice a week with high iodine water combined with subcutaneous injection of thyroglobulin. From the fifth to eighth weeks, 36 rats were immunized once a week. From the fifth week, the model group with liver depression and spleen deficiency syndrome of Traditional Chinese Medicine was reproduced with chronic restraint stress, excessive fatigue and eating incoherence methods. The modelrats were randomly divided into model group, Xiaoyao Powder group and Jinshuibao group. Rats in Xiaoyao Powder group were gavaged with 13.63 g/(kg·d) Xiaoyao Powder modified granule suspension, and rats in Jinshuibao group were gavaged with 477 mg/(kg·d) Jinshuibao suspension, twice a day, for 8 weeks.The levels of serum FT3, FT4, TSH, TGAb and TPOAb were detected by ELISA; the expression of miR326, IL-17 mRNA, IL-4 mRNA and IFN-γ mRNA were detected by PCR. The expression of Ets-1 protein in thyroid tissue was detected by Wes method, and the proportion of CD4 + IFNγ + T cells, CD4 + IL-4 + T cells and CD4 + IL-17 + T cells were detected by flow cytometry, HE staining was used to detect the pathological manifestations of thyroid tissue in each group. Results:Compared with the model group, the serum TSH [(3 328.88±724.45) pg/ml vs. (1 900.25±203.91) pg/ml] in Xiaoyao Powder group increased ( P<0.01), TGAb [(63.60±9.01) IU/ml vs. (96.19±10.74) IU/ml] and TPOAb [(6.84±1.45) IU/ml vs. (11.62±2.06) IU/ml] decreased ( P<0.01), and the expression of miR326 (3.57±0.57 vs. 7.63±0.90),IL-17 mRNA (6.71±0.97 vs. 13.02±1.18) significantly decreased ( P<0.01), the expression of Ets-1 (0.71±0.40 vs. 0.39±0.02) significantly increased ( P<0.01), the ratio of CD4 +IFN-γ + T cell [(13.10±2.23)% vs. (20.7±2.07)%], CD4 +IL-17 + T cell ratio [(18.90±1.31)% vs. (25.1±1.03)%] significantly decreased ( P<0.01), and thyroid histopathology changed significantly. Conclusion:Modified Xiaoyao Powder could regulate the expression of target protein Ets-1 upward, inhibit the differentiation of Th17 cells and further reduce the expression of IL-17 mRNA by regulating the expression of mir-326 downward in the thyroid tissue of EAT rats, so as to improve the inflammatory response of rats with liver depression and spleen deficiency.
ABSTRACT
Objective:To analyze the clinical efficacy and safety of endoluminal treatment of complex renal artery aneurysm (RAA).Methods:The clinical data and follow-up results of 19 patients with complex RAA admitted to Renji Hospital, Shanghai Jiaotong University School of Medicine from November 2014 to September 2021 were retrospectively analyzed. Two patients were treated with simple spring coil embolization into the aneurysmal artery, 14 patients were treated with simple spring coil embolization of the aneurysmal cavity, and 3 patients were treated with stent-assisted + spring coil embolization technique. Based on the location of the aneurysm, RAA were classified into type Ⅰ, Ⅱ, and Ⅲ. 7 patients with type Ⅰ, 10 patients with type Ⅱ, and 2 patients with type Ⅲ were studied. Variance analysis was used to compare the differences in glomerular filtration rate(GFR) of the affected side when the tumor was located at different locations, and Pearson was used to analyze the correlation between the number of coils implanted and the size of the tumor and GFR.Results:Ten of the 19 patients who were underwent successful endoluminal intervention. The average size of the patients′ aneurysms was (20.89±6.65) mm, and the average number of spring coils implanted was 8.22±3.08. The preoperative and postoperative serum creatinine were in the normal range, and no RAA tumor enlargement or recurrence was found during the follow-up period. The postoperative GFR was abnormal in patients with type Ⅰ, type Ⅱ, and type Ⅲ renal aneurysms, and the mean GFR value differed among the three types of patients( P=0.003). There was a negative correlation between the postoperative GFR values of the affected kidney and the number of spring coils implanted ( P=0.047), and no significant relationship between GFR and aneurysm size. Conclusion:The endovascular technique is an effective and safe means of treating complex RAA.

ABSTRACT
ObjectiveTo evaluate the effect of Wenshen Yangxue prescription （WSYX） on the outcome of in vitro fertilization-embryo transfer （IVF-ET） in poor ovarian responders and the safety. MethodA total of 116 eligible patients who were admitted to Beijing Obstetrics and Gynecology Hospital in June 2016-June 2019 were randomized into the experimental group and the control group with random number table method （58 in either group）. Conventional controlled ovarian hyperstimulation （COH） was directly implemented in the control group， while the experimental group was intervened with WSYX for 3 menstrual cycles before the COH. The pregnant patients were observed till childbirth and the non-pregnant patients for 12 months. Gonadotropins （Gn） dosage and the days of use were recorded. Serum levels of follicle-stimulating hormone （FSH）， basal FSH （bFSH）， basal luteinizing hormone （bLH）， and basal estrogen （bE2）， endometrial thickness， and antral follicle count （AFC） before and after treatment were measured. The serum levels of estrogen （E2）， progesterone （P）， and luteinizing hormone （LH） on the day of human chorionic gonadotropin （HCG） injection， and levels of FSH， LH， E2， testosterone （T）， and P in follicular fluid 36 h after HCG injection were determined. Number of fertilization， rate of fertilization， number of high-quality embryos， cycle cancellation rate， clinical pregnancy rate， and live birth rate were evaluated. The traditional Chinese medicine （TCM） syndrome scores before and after treatment were recorded. Liver and kidney functions were detected before and after treatment， and adverse reactions during treatment were recorded. ResultCompared with the control group， the experimental group showed the decrease in the days of Gn use and dosage of Gn （P<0.05）， endometrium thickening （P<0.05）， and increase in oocytes obtained， levels of E2 and LH on the day of HCG injection， and ovarian reserve function. Moreover， in follicular fluid 36 h after HCG injection， the reduction in level of FSH （P<0.05）， rise of levels of LH and E2 （P<0.05）， and insignificant changes in levels of T and P in the experimental group were observed as compared with those in the control group. In addition， larger number of fertilization， more available embryos， and higher rate of high-quality embryos were observed in the experimental group than in the control group （P<0.05）. The experimental group demonstrated improvement in quality of oocytes， decrease in cycle cancellation rate ， and increase in clinical pregnancy rate and live birth rate compared with the control group. The TCM syndrome score in experimental group was decreased after treatment compared with that before treatment （P<0.05）. No serious adverse reactions occurred in two groups during treatment and the safety indexes before and after treatment were all within the normal ranges. ConclusionWSYX can reduce the use duration and dosage of Gn in infertile patients receiving IVF-ET， improve the quality of oocytes， increase the rate of high-quality embryos， and improve the pregnancy outcome of IVF-ET patients.
ABSTRACT
ObjectiveTo study the effect of Jinlida granules on visceral fat accumulation and its induced inflammatory response in prediabetic rats. MethodMale SD rats were randomly divided into normal group， model group， Jinlida low-dose group （1.5 g·kg-1）， Jinlida high-dose group （3.0 g·kg-1） and atorvastatin group （10 mg·kg-1）. Prediabetic rat model was established using high-carbohydrate， high-fat diet combined with low-dose streptozotocin （STZ） by multiple small-dose intraperitoneal injections. After 8 weeks of modeling and drug intervention for 13 consecutive weeks， body weight， oral glucose tolerance test（OGTT）， fasting blood glucose （FBG）， fasting insulin （FINS）， insulin resistance index （HOMA-IR）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） were measured in each group of rats. The content of visceral fat was quantified by micro-computed tomography （Micro-CT）. Hematoxylin-eosin staining （HE） was used to observe the pathological changes of fat cells. The levels of tumor necrosis factor-α （TNF-α） and interleukin- 6 （IL-6） in rat visceral fat and serum were determined by enzyme linked immunosorbent assay （ELISA）. The expression of macrophage marker CD68 in visceral fat was detected by immunofluorescence and Western blot. ResultCompared with normal group， model group had increased oral glucose tolerance， FBG， FINS， HOMA-IR， TC， LDL-C （P<0.01）， elevated body weight and visceral fat accumulation （P<0.05， P<0.01）， enhanced CD68 protein expression and TNF-α and IL-6 levels （P<0.01）， decreased HDL-C （P<0.01）， and abnormal hypertrophy of adipocytes. Compared with model group， Jinlida high- and low-dose groups lowered oral glucose tolerance， HOMA-IR， TC and LDL-C （P<0.05， P<0.01）， body weight and visceral fat accumulation （P<0.05）， and CD68 protein expression and TNF-α and IL-6 levels （P<0.05， P<0.01） and lessened hypertrophy of fat cells. ConclusionJinlida can improve the insulin resistance in prediabetic rats by reducing visceral fat accumulation and its induced inflammatory response， which provides a new pharmacological basis for clinical treatment of prediabetes by Jinlida granules.
ABSTRACT
ObjectiveTo study the effects of Wendantang on the expression of miRNA-219， N-methyl-D-aspartate receptor 2B （NR2B）， disrupted in schizophrenia 1 （DISC1）， and Ca2+/calmodulin-dependent protein kinase Ⅱγ （CaMKⅡγ） in the frontal lobe of rats with schizophrenia. MethodSixty rats were randomly divided into six groups， namely normal group， model group， high-， medium-， and low-dose Wendantang groups， and clozapine group， with 10 rats in each group. Rats in high-， medium-， and low-dose Wendantang groups were intragastric with 40， 20， and 10 g·kg-1 Wendantang， and the ones in clozapine group were intragastric with 0.02 g·kg-1 clozapine， those in normal and model group were intragastric with equal volume of normal saline， once a day. After 21 days of administration， rats in all groups except for the normal group were injected with 0.6 mg·kg-1 dizocilpine maleate （MK-801） into the left abdominal cavity for inducing acute schizophrenia. The stereotypic behavior and ataxia in rats were scored according to SAMS and HOFFMAN criteria. The morphological changes in the prefrontal cortex were observed by hematoxylin-eosin （HE） staining. The protein expression levels of NR2B, DISC1 and CaMKⅡγ in the frontal lobe was detected by Western blot. The mRNA expression levels of miRNA-219 was detected by real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）. ResultCompared with normal group， the model group exhibited significantly increased stereotypic behavior and ataxia scores （P<0.01）， karyopyknosis and karyolysis in most neurons of the prefrontal cortex， and down-regulated NR2B， DISC1， and CaMKⅡγ protein expression （P<0.01） and miRNA-219， NR2B， DISC1， and CaMKⅡγ mRNA expression （P<0.01）. Compared with model group， Wendantang high-， medium-， and low-doses group lowered the scores of stereotypic behavior and ataxia at 50， 60 mmin（P<0.05，P<0.01）. In high- and medium-dose Wendantang groups， the neurons in the prefrontal cortex were densely arranged. The karyopyknosis and karyolysis were alleviated to varying degrees. The NR2B protein expression in the frontal lobe was up-regulated （P<0.01）. In the medium- and low-dose Wendantang groups， the DISC1 protein expression in the frontal lobe was up-regulated （P<0.05，P<0.01）. Wendantang at each dose significantly increased the CaMKⅡγ protein expression （P<0.05） and miRNA-219， NR2B， DISC1， and CaMKⅡγ mRNA expression in the frontal lobe （P<0.05，P<0.01）. ConclusionWendantang improves the scores of stereotypical behavior and ataxia， relieves the karyopyknosis and karyolysis of neurons in the prefrontal cortex， and increases the expression levels of miRNA-219， NR2B， DISC1， and CaMKⅡγ of rats with schizophrenia， so as to alleviate the schizophrenic-like symptoms and schizophrenia.
ABSTRACT
Objective:To evaluate the mid-term clinical efficacy of drug-coated balloons (DCB)in the treatment of femoro-popliteal artery TASC Ⅱ C/D de novo stenosis and in-stent restenosis.Methods:A total of 126 patients with TASC Ⅱ C/D femoro-popliteal artery stenosis treated with DCB in Renji Hospital and Pudong New Area People's Hospital from December 2016 to August 2020 were retrospectively enrolled, including 74 cases of de novo stenosis (de novo group) and 52 cases of in-stent restenosis (ISR group). The clinical data and lesion characteristics were analyzed; the primary patency rate, primary-assisted patency rate, secondary patency rate, and the freedom from target lesion revascularization (f-TLR)rate were evaluated; the perioperative complications, mortality and amputation rate were compared between two groups. Kaplan-Meier method was used to evaluate the patency rate of target vessel lesions, and Cox regression analysis was used to evaluate the relative risk factors.Results:There were 6 patients died in each group during the followup period. The lesion length of the de novo and ISR groups were (21.25±12.64) cm and (34.71±12.02) cm, respectively( t=33.74, P<0.001). The popliteal artery involvement was 33.8% (25/74) in the de novo group and 15.4% (8/52) in the ISR group (χ 2=5.35, P=0.021). The operational success rate was 100.0% in both groups, and the perioperative complication rate was 6.8% (5/74) in the de novo group and 1.9% (1/52) in ISR group. The median follow-up time was 22 month and 17 months; the mean follow-up time were(19.78 ± 11.02) months and (20.02 ± 11.32) months in the de novo group and ISR group, respectively. The primary patency rates at 6, 12 and 24 months after intervention were 89.1%, 73.4%, 50.8% in the Denovo group, and 87.8%, 68.8%, 42.0% in the ISR group, respectively; the primary assisted patency rate was 90.7%, 78.4%, 62.8% in the de novo group, and 89.3%,77.1%, 62.8% in the ISR group, respectively; the secondary patency rate was 95.1%,95.1%, 88.7% in de novo group, and 94.9%, 88.9%, 84.3% in ISR group, respectively; the f-TLR rate was 97.3%, 88.6%, 79.2% in de novo group, and 90.0%, 77.7%, 74.7% in ISR group, respectively (all P>0.05). Cox regression analysis showed that P2 and P3 segment involvement of the popliteal artery were independent factors affecting the patency rate of target lesion. Conclusions:The mid-term clinical efficacy of DCB in the treatment of TASC Ⅱ C/D femoro-popliteal artery de novo stenosis and in-stent restenosis is satisfactory.

Methods Forty serum samples from cerebral cysticercosis patients, 100 serum samples from healthy volunteers, 30 serum samples from paragonimiasis skrjabini patients, 17 serum samples from cystic echinococcosis and 19 serum samples from subcutaneous or cerebral sparganosis patients were collected and detected using anti-cysticercus IgG, IgG4 or IgM antibody test kits (brand A) and the anti-cysticercus IgG antibody test kit (brand B). The sensitivity, specificity and false negative rate of the four kits for detection of cysticercosis were estimated. Results The anti-cysticercus IgG, IgG4 or IgM antibody test kits (brand A) showed 95.00% (38/40), 87.50% (35/40), 7.50% (3/40) sensitivities and 98.00% (98/100), 100.00% (100/100) and 100.00% (100/100) for detection of cysticercosis, while the anti-cysticercus IgG antibody test kit (brand B) presented a 75.00% (30/40) sensitivity and 100.00% (100/100) specificity for detection of cysticercosis. The sensitivity for detection of cysticercosis was significantly higher by the anti-cysticercus IgG antibody test kit (brand A) than by the anti-cysticercus IgG antibody test kit (brand B) (χ2 = 6.28, P < 0.05); however, no significant difference was seen in the specificity by two kits (χ2 = 2.01, P > 0.05). The four ELISA kits showed overall false positive rates of 37.88% (25/66), 22.73% (15/66), 62.12% (41/66) and 15.15% (10/66) for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 37.61, P < 0.05), and the anti-cysticercus IgG antibody test kit (brand A) presented the highest overall false positive rate for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 7.56, P’ < 0.008), while a higher overall false positive rate was seen for detection of paragonimiasis, echinococcosis and sparganosis by the anti-cysticercus IgG antibody test kit (brand A) than by the anti-cysticercus IgG antibody test kit (brand B) (χ2 = 8.75, P’ < 0.008). The four ELISA kits showed false positive rates of 40.00% (12/30), 16.67% (5/30), 76.67% (23/30) and 13.33% (4/30) for detection of paragonimiasis (χ2 = 32.88, P < 0.05) and 21.05% (4/19), 26.32% (5/19), 73.68% (14/19) and 15.79% (3/19) for detection of sparganosis (χ2 = 19.97, P < 0.05), and the highest false positive rates were found by the anti-cysticercus IgM antibody test kit (brand A) for detection of paragonimiasis and sparganosis (all P’ < 0.008). However, the four ELISA kits showed comparable false positive rates of 52.94% (9/17), 29.41% (5/17), 23.53% (4/17) and 17.65% (3/17) for detection of echinococcosis (χ2 = 8.24, P > 0.05). In addition, the anti-cysticercus IgM anti-body test kit (brand A) showed false positive rates of 76.67% (23/30), 23.53% (4/17) and 73.68% (14/19) for detection of paragonimiasis, echinococcosis and sparganosis (χ2 = 14.537, P < 0.05), with the lowest false positive rate seen for detection of echinococcosis (χ2 = 14.537, P’ < 0.014), while no significant differences were seen in the false positive rate for detection of paragonimiasis, echinococcosis and sparganosis by other three ELISA kits (all P > 0.05). Conclusions The four anti-cysticercus IgG, IgG4 or IgM antibody test kits exhibit various efficiencies for serodiagnosis of cysticercosis. The anti-cysticercus IgG antibody test kit (brand A) has a high sensitivity for serodiagnosis of cysticercosis; however, it still needs to solve the problems of cross-reaction with other parasitic diseases and stability.
ABSTRACT
Objective To investigate the association between short-term exposure to ambient air pollution and hospital admission for ischemic stroke among older adults. Methods Using clinical monitoring data from China National Health Commission, we identified 124 297 individuals from Guangzhou, Guangdong province, China who were 60 years or older and were admitted to hospital for ischemic stroke in 2016-2019. We used a time-stratified case-crossover design and employed the conditional logistic regression model to investigate the exposure-response association between short-term exposure to air pollution and hospital admission for ischemic stroke. Based on each subject's residential address and pollutant data from its neighboring air quality monitoring stations, we used an inverse distance weighting method to assess individual-level exposure to PM2.5, PM10, SO2, NO2, CO and O3 on each of the case and control days. Results In single-pollutant models, each 10 µg/m3 increase of PM2.5, PM10, SO2, NO2, CO and O3 was associated with a 0.46% (95% confidence interval [CI]: 0.13-1.36%, lag 2 d), 0.66% (1.38-2.93%, lag 02 d), 3.39% (0.07-0.21%, lag 2 d), 1.47% (0.07-0.21%, lag 02 d), 0.06% (0.07-0.21%, lag 02 d) and 0.18% (0.07-0.21%, lag 3 d) increase in odds of hospital admission, respectively. The results of 2-pollutant models showed that the association of exposure to SO2, NO2 and O3 with hospital admission for ischemic stroke remained stable with adjustment for each of the other air pollutants. Conclusions Short-term exposure to ambient air pollution, especially SO2, NO2 and O3, was associated with increased risk of hospital admission for ischemic stroke in older adults.
ABSTRACT
Objective To investigate the changes in the awareness rate of Taenia solium taeniasis and cysticercosis control knowledge among medical professionals before and after training in Fangcheng County, a disease-elimination pilot area of Henan Province, so as to evaluate the effectiveness of the training. Methods Three townships in Fangcheng County were randomly selected as the study townships, including Dushu, Bowang and Yangji townships, while Erlangmiao, Yanglou and Xiaoshidian townships in the county were randomly selected as the control townships. The grassroots medical professionals in the study townships were given once training on T. solium taeniasis and cysticercosis control knowledge each year from 2016 to 2020, while those in the control townships were given no interventions. All village-level doctors and a part of township-level public health professionals were sampled from the study and control townships as intervention and control groups. The baseline and final assessments of the awareness of T. solium taeniasis and cysticercosis control knowledge were performed using questionnaire survey in intervention and control groups in 2016 and 2020, and the awareness of T. solium taeniasis and cysticercosis control knowledge was compared between the two groups. Results A total of 663 medical professionals were investigated in Fangcheng County from 2016 to 2020, including 474 participants in the intervention group and 189 participants in the control group. Results from the 2016 baseline survey showed that the awareness rate of T. solium taeniasis and cysticercosis control knowledge was 28.83% (47/163) among grassroots medical professionals in Fangcheng County, and there were no significant differences in the awareness between the intervention (32.47%, 25/77) and control groups (25.58%, 22/86) (χ2 = 0.939, P > 0.05), between men (30.50%, 43/141) and women (18.18%, 4/22) (χ2 = 1.406, P > 0.05) or between village- (31.39%, 43/137) and township-level medical professionals (15.38%, 4/26) (χ2 = 2.727, P > 0.05), while significant differences were found in the awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in terms of education levels (χ2 = 8.190, P < 0.05) and duration of working experiences (χ2 = 12.617, P < 0.05), and the awareness rate of T. solium taeniasis and cysticercosis control knowledge increased with education levels among medical professionals (χ2 = 6.768, P < 0.05). Only 5.52% (9/163) of the medical professionals had a history of diagnosis and therapy of T. solium taeniasis or cysticercosis, and only 1.23% (2/163) received training on T. solium taeniasis and cysticercosis control knowledge during the past 5 years. Results from the 2020 questionnaire survey showed a higher awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in the intervention group (93.55%, 116/124) than in the control group (46.60%, 48/103) (χ2 = 61.845, P < 0.05), and no significant differences were seen in the awareness rate of T. solium taeniasis and cysticercosis control knowledge among medical professionals in terms of gender, level of medical professionals, duration of working experiences or history of diagnosis/therapy of T. solium taeniasis and cysticercosis in the intervention group (χ2 = 1.089, 0.140, 0.081 and 0.453, all P values > 0.05), while there was a significant difference in the awareness rate among medical professionals with different education levels (χ2 = 36.338, P < 0.05). In addition, the awareness rate of T. solium taeniasis and cysticercosis control knowledge significantly increased among medical professionals with various chracteristics in 2020 than in 2016. Conclusions In the low-prevalence areas of T. solium taeniasis and cysticercosis, long-term and persistent training may improve the awareness of T. solium taeniasis and cysticercosis control knowledge among grassroots medical professionals, which facilitates the timely identification of T. solium taeniasis and cysticercosis and the establishment of a sensitive disease surveillance system.
ABSTRACT
Objective:To investigate the optimal monoenergetic level of virtual monoenergetic images (VMI) in transplanted renal artery on a dual-layer spectral detector CT.Methods:A retrospective study was performed on 16 renal transplant patients who underwent transplanted renal angiography on a dual-layer spectral detector CT in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from June 2020 to April 2021. Conventional 120 kVp polyenergetic images (PI) were reconstructed, and virtual monoenergetic images (VMIs) in range of 40-200 keV with interval of 10 keV were reconstructed, too. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of 120 kVp PI and VMIs were measured. Meanwhile, the subjective scores of the display of transplanted renal artery were performed on volume rendering images of 120 kVp PI and VMIs. Spearman correlation analysis was used to explore the correlation between energy levels and SNR or CNR. Rank sum tests were performed to compare the parameters of image quality between the VMI which had the highest SNR and CNR, and the other VMIs, or 120 kVp PI.Results:Among the VMIs, SNR or CNR was negatively correlated with energy levels ( r =-0.86 and -0.88, all P<0.001). The SNR [22.80(18.57, 34.16)] and CNR [35.38(25.97, 39.01)] of 40 keV VMI were the highest, and significantly higher than that of 120 kVp PI and 50-200 keV VMIs, all the differences were statistically significant (all P<0.05). The subjective scores of 40 keV VMI and 120 kVp PI were 5 (5, 5) and 4 (3, 5), respectively. The score of 40 keV VMI was significantly higher than that of 120 kVp PI ( Z=-2.60, P=0.009). There were no significant differences in subjective scores between 40 keV VMI and 50-70 keV VMIs ( Z=-1.00, -1.41, -1.73, P=0.317, 0.157, 0.083), but the subjective score of 40 keV VMI was higher than that of 80-200 keV VMIs and the differences were statistically significant (all P<0.05). Conclusions:As for the images of transplanted renal angiography on a dual-layer spectral detector CT, the image quality of 40 keV VMI was best, thus 40 keV was the optimal monoenergetic level.
ABSTRACT
The pandemic of Corona Virus Disease 2019 (COVID-19) continues, which shows the concentrated or sporadic cases in multiple places. Current COVID situation is still complex. During the COVID-19, routine diagnosis and treatment of liver cancer patients has been affected in different degrees. Under the premise of following the treatment guidelines, how to reduce the risk of infection of patients and medical staff, utilize limited medical resources to maximally ensure anti-tumor treatment and related emergency treatment, and help patients get through the epidemic period is a problem for liver oncologists. Thus, experts of liver cancer treatment related disciplines of Zhongshan Hospital, Fudan University have written the Expert guidance on overall management of liver cancer during the COVID-19, which aims to provide references for liver oncolo-gists to conduct clinical work safely and effectively under the epidemic prevention and control, and to help patients fight against the epidemic smoothly.
ABSTRACT
Objective:In order to Understand the cognition of breastfeeding needs in perinatal period among parturients, International Board Certified Lactation Consultants and obstetric nurses, and analyze their differences, provide a theoretical basis for the development of interventions.Methods:Using the objective sampling method, 10 parturients, 6 International Board Certified Lactation Consultants and 6 obstetric nurses from a tertiary A specialist hospital in Shanghai from February to June in 2021 were selected for semi-structured depth interviews. The inteniew focused on the needs of breastfeeding in different stages of perinatal period.Results:Through analysis and induction, the following three themes were finally condensed. Cognitive differences in prenatal education: post-hospital breastfeeding support. Parturients lack prenatal awareness of breastfeeding initiatives and prefer problem-oriented feedback after childbirth to be addressed in a timely manner, but healthcare professionals consider it necessary to provide prenatal breastfeeding education to pregnant women. Inpatient nursing supports cognitive similarities and differences: there was agreement between parturients and healthcare professionals on strengthening post-natal health education and assessing needs for psychological change. The difference is that parturients are more likely to have information and guidance on milking, however, healthcare professionals believe that the focus is on providing guidance on breastfeeding techniques and strengthening professional training for medical personnel. Breastfeeding supports cognitive similarities and differences after discharge: both parturient and healthcare professionals want family and peer support in post-hospital breastfeeding support. The difference is that parturients want to be able to keep in touch with healthcare professionals on feedback issues, but healthcare professionals believe that further community support is needed.Conclusion:Parturient and healthcare professionals have different cognition of perinatal breastfeeding needs. Targeted interventions and personalized breastfeeding plans should be developed for their different cognitions, with a view to further improving the rate of exclusive breastfeeding in China and achieving the goal of healthy development for all.
ABSTRACT
The mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway is widely activated by a variety of extracellular stimuli, and its dysregulation is associated with the proliferation, invasion, and migration of cancer cells. ERK1/2 is located at the distal end of this pathway and rarely undergoes mutations, making it an attractive target for anticancer drug development. Currently, an increasing number of ERK1/2 inhibitors have been designed and synthesized for antitumor therapy, among which representative compounds have entered clinical trials. When ERK1/2 signal transduction is eliminated, ERK5 may provide a bypass route to rescue proliferation, and weaken the potency of ERK1/2 inhibitors. Therefore, drug research targeting ERK5 or based on the compensatory mechanism of ERK5 for ERK1/2 opens up a new way for oncotherapy. This review provides an overview of the physiological and biological functions of ERKs, focuses on the structure-activity relationships of small molecule inhibitors targeting ERKs, with a view to providing guidance for future drug design and optimization, and discusses the potential therapeutic strategies to overcome drug resistance.
