Objective:To evaluate a surgical approach for partial resection of the tenth rib through a retroperitoneal approach for the exposure of Crawford type IV thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm from 2014 to 2019.Methods:A retrospective analysis was conducted on clinical data and follow-up results of 7 patients who underwent treatment for Crawford type IV thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm through partial resection of the tenth rib via a retroperitoneal approach.Results:One case (14.3%) had associated Marfan syndrome, and 5 cases (71.4%) underwent left renal artery reconstruction. None of the patients experienced severe complications such as cardiopulmonary complications or renal failure postoperatively, and there was no statistically significant difference in serum creatinine levels between preoperative and postoperative stages during hospitalization ( P=0.205). Follow-up examinations showed no long-term vascular stenosis. Conclusions:Partial resection of the tenth rib through a retroperitoneal approach can avoid incisions of the pleura and diaphragm. It allows for the exposure of the aorta below the diaphragm and has the ability to treat aortic diseases below the diaphragm with smaller incisions and lower complication risks.

Diabetes mellitus and adverse outcomes after carotid endarterectomy: A systematic review and meta-analysis / 中华医学杂志(英文版)

BACKGROUND@#There is still uncertainty regarding whether diabetes mellitus (DM) can adversely affect patients undergoing carotid endarterectomy (CEA) for carotid stenosis. The aim of the study was to assess the adverse impact of DM on patients with carotid stenosis treated by CEA.@*METHODS@#Eligible studies published between 1 January 2000 and 30 March 2023 were selected from the PubMed, EMBASE, Web of Science, CENTRAL, and ClinicalTrials databases. The short-term and long-term outcomes of major adverse events (MAEs), death, stroke, the composite outcomes of death/stroke, and myocardial infarction (MI) were collected to calculate the pooled effect sizes (ESs), 95% confidence intervals (CIs), and prevalence of adverse outcomes. Subgroup analysis by asymptomatic/symptomatic carotid stenosis and insulin/noninsulin-dependent DM was performed.@*RESULTS@#A total of 19 studies (n = 122,003) were included. Regarding the short-term outcomes, DM was associated with increased risks of MAEs (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 5.1%), death/stroke (ES = 1.61, 95% CI: [1.13-2.28], prevalence = 2.3%), stroke (ES = 1.55, 95% CI: [1.16-1.55], prevalence = 3.5%), death (ES = 1.70, 95% CI: [1.25-2.31], prevalence =1.2%), and MI (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 1.4%). DM was associated with increased risks of long-term MAEs (ES = 1.24, 95% CI: [1.04-1.49], prevalence = 12.2%). In the subgroup analysis, DM was associated with an increased risk of short-term MAEs, death/stroke, stroke, and MI in asymptomatic patients undergoing CEA and with only short-term MAEs in the symptomatic patients. Both insulin- and noninsulin-dependent DM patients had an increased risk of short-term and long-term MAEs, and insulin-dependent DM was also associated with the short-term risk of death/stroke, death, and MI.@*CONCLUSIONS@#In patients with carotid stenosis treated by CEA, DM is associated with short-term and long-term MAEs. DM may have a greater impact on adverse outcomes in asymptomatic patients after CEA. Insulin-dependent DM may have a more significant impact on post-CEA adverse outcomes than noninsulin-dependent DM. Whether DM management could reduce the risk of adverse outcomes after CEA requires further investigation.

Acupuncture for chronic prostatitis/chronic pelvic pain syndrome: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the short-term efficacy, long-term efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).@*METHODS@#Forty-two patients with CP/CPPS were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases). The patients in the acupuncture group were treated with acupuncture at bilateral Zhongliao (BL 33), Huiyang (BL 35), Shenshu (BL 23) and Sanyinjiao (SP 6); the needling depth of Zhongliao (BL 33) and Huiyang (BL 35) was 60 to 80 mm, while Shenshu (BL 23) and Sanyinjiao (SP 6) was directly punctured of 30 mm. The patients in the sham acupuncture group were treated with acupuncture at non-acupoints, including points 2 cm next to Shenshu (BL 23), Zhongliao (BL 33) and Huiyang (BL 35), and the midpoint of the connecting line between the spleen meridian and the kidney meridian. All the non-acupoints were treated with directly puncture of 2 to 3 mm. The needles were left for 30 min in both groups, once every other day in the first four weeks, three times a week, and twice a week in the next four weeks, totally 20 treatments. Before treatment, after treatment and in follow-up of 24 weeks after treatment completion, the National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) score and urinary flow rate were observed in both groups; the clinical efficacy and safety were evaluated.@*RESULTS@#Compared with those before treatment, the pain and discomfort scores, urination symptoms scores, quality of life scores and total scores of NIH-CPSI in both groups were reduced after treatment in the two groups (P<0.01), while each item score and total score of NIH-CPSI in the acupuncture group were reduced in follow-up (P<0.01, P<0.05). After treatment and in follow-up, each item score and total score of NIH-CPSI in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). After treatment, the maximum and average urinary flow rates in the acupuncture group were higher than those before treatment (P<0.05), and the average urinary flow rate in the acupuncture group was higher than that in the sham acupuncture group (P<0.05). The total effective rate was 75.0% (15/20) in the acupuncture group, which was higher than 42.9% (9/21) in the sham acupuncture group (P<0.05). No significant adverse reactions were observed in the two groups, and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05).@*CONCLUSION@#Acupuncture could effectively alleviate the clinical symptoms, improve quality of life, and has a sustained, safe and reliable therapeutic effect in patients with CP/CPPS.

Clinical characteristics and short-term prognosis of 22 cases with SARS-CoV-2 infection associated acute encephalopathy / 中华儿科杂志

Objective: To investigate the clinical features and short-term prognosis of patients with SARS-CoV-2 infection associated acute encephalopathy (AE). Methods: Retrospective cohort study. The clinical data, radiological features and short-term follow-up of 22 cases diagnosed with SARS-CoV-2 infection associated AE in the Department of Neurology, Beijing Children's Hospital from December 2022 to January 2023 were retrospectively analyzed. The patients were divided into cytokine storm group, excitotoxic brain damage group and unclassified encephalopathy group according to the the clinicopathological features and the imaging features. The clinical characteristics of each group were analyzed descriptively. Patients were divided into good prognosis group (≤2 scores) and poor prognosis group (>2 scores) based on the modified Rankin scale (mRS) score of the last follow-up. Fisher exact test or Mann-Whitney U test was used to compare the two groups. Results: A total of 22 cases (12 females, 10 males) were included. The age of onset was 3.3 (1.7, 8.6) years. There were 11 cases (50%) with abnormal medical history, and 4 cases with abnormal family history. All the enrolled patients had fever as the initial clinical symptom, and 21 cases (95%) developed neurological symptoms within 24 hours after fever. The onset of neurological symptoms included convulsions (17 cases) and disturbance of consciousness (5 cases). There were 22 cases of encephalopathy, 20 cases of convulsions, 14 cases of speech disorders, 8 cases of involuntary movements and 3 cases of ataxia during the course of the disease. Clinical classification included 3 cases in the cytokine storm group, all with acute necrotizing encephalopathy (ANE); 9 cases in the excitotoxicity group, 8 cases with acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) and 1 case with hemiconvulsion-hemiplegia syndrome; and 10 cases of unclassified encephalopathy. Laboratory studies revealed elevated glutathione transaminase in 9 cases, elevated glutamic alanine transaminase in 4 cases, elevated blood glucose in 3 cases, and elevated D-dimer in 3 cases. Serum ferritin was elevated in 3 of 5 cases, serum and cerebrospinal fluid (CSF) neurofilament light chain protein was elevated in 5 of 9 cases, serum cytokines were elevated in 7 of 18 cases, and CSF cytokines were elevated in 7 of 8 cases. Cranial imaging abnormalities were noted in 18 cases, including bilateral symmetric lesions in 3 ANE cases and "bright tree appearance" in 8 AESD cases. All 22 cases received symptomatic treatment and immunotherapy (intravenous immunoglobulin or glucocorticosteroids), and 1 ANE patient received tocilizumab. The follow-up time was 50 (43, 53) d, and 10 patients had a good prognosis and 12 patients had a poor prognosis. No statistically significant differences were found between the two groups in terms of epidemiology, clinical manifestations, biochemical indices, and duration of illness to initiate immunotherapy (all P>0.05). Conclusions: SARS-CoV-2 infection is also a major cause of AE. AESD and ANE are the common AE syndromes. Therefore, it is crucial to identify AE patients with fever, convulsions, and impaired consciousness, and apply aggressive therapy as early as possible.

Mechanism of tonifying kidney and activating blood therapy for premature ovarian failure:a review / 中国中药杂志

Healthy birth and child development are the prerequisite for improving the overall quality of the population. However, premature ovarian failure(POF) threatens the reproductive health of women. The incidence of this disease has been on the rise, and it tends to occur in the young. The causes are complex, involving genetics, autoimmune, infectious and iatrogenic factors, but most of the causes remain unclear. At the moment, hormone replacement therapy and assisted reproductive technology are the main clinical approaches. According to traditional Chinese medicine(TCM), kidney deficiency and blood stasis are one of the major causes of POF, and TCM with the effects of tonifying kidney and activating blood has a definite effect. Through clinical trials, TCM prescriptions for POF have excellent therapeutic effect as a result of multi-target regulation and slight toxicity. In particular, they have no obvious side effects. A large number of studies have shown that the kidney-tonifying and blood-activating TCM can regulate the neuroendocrine function of hypothalamic-pituitary-ovarian axis, improve ovarian hemodynamics and microcirculation, reduce the apoptosis of granulosa cells, alleviate oxidative stress injury, and modulate immunologic balance. The mechanism is that it regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), vascular endothelial growth factor(VEGF), transforming growth factor(TGF)-β/Smads, nuclear factor E2-related factor 2(Nrf2)/antioxidant response element(ARE), and nuclear factor-kappa B(NF-κB) signaling pathways. This article summarized the pathological mechanisms of tonifying kidney and activating blood TCM in the prevention and treatment of POF and explored the biological basis of its multi-pathway and multi-target characteristics in the treatment of this disease. As a result, this study is expected to serve as a reference for the treatment of POF with the tonifying kidney and activating blood therapy.

Protective effect of excretory-secretory proteins from Trichinella spiralis muscle larvae against myocardial injury in septic mice / 南方医科大学学报

OBJECTIVE@#To evaluate the protective effect of excretory-secretory proteins from Trichinella spiralis muscle larvae (Ts-MES) on sepsis-induced myocardial injury in mice.@*METHODS@#Eighty male BALB/C mice were randomized equally into sham-operated group, myocardial injury group, Ts-MES treatment group and dexamethasone treatment group. In the latter 3 groups, sepsis-induced myocardial injury models were established by cecal ligation and perforation; the sham operation was performed by exposure of the cecum without ligation or perforation. Forty minutes after the operation, the mice were given intraperitoneal injections 150 μL PBS, 20 μg TS-MES or 0.3 mg/kg dexamethasone as indicated. At 12 h after the operation, 6 mice were randomly selected from each group for echocardiography, and 8 mice were used for observing the survival rate within 72 h. The remaining 6 mice were examined for myocardial pathologies with HE staining and serum levels of NTPro-BNP and cTnI with ELISA; the expressions of TNF-α, IL-6, IL-10 and TGF-β in the serum and myocardial tissue were detected using ELISA and qRT-PCR.@*RESULTS@#Compared with the sham-operated mice, the septic mice showed significantly decreased cardiac function indexes (LVEF, LVFS, and E/A) with lowered survival rate within 72 h (P < 0.001) and significantly higher myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.01). Treatment with TS-MES significantly improved the cardiac function and 72-h survival rate (P < 0.05) and lowered the myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.05) in the septic mice. Compared with the sham-operated mice, the septic mice had obviously increased TNF-α and IL-6 levels in the serum and myocardial tissue (P < 0.001), which were significantly lowered by treatment with TS-MES (P < 0.05). TS-MES and dexamethasone both increased the levels of IL-10 and TGF-β in the septic mice, but the changes were significant only in TS-MES-treated mice (P < 0.05).@*CONCLUSION@#Ts-MES are capable of protecting against myocardial injury in septic mice by reducing the production of pro-inflammatory cytokines and enhancing the levels of regulatory cytokines.

Network Meta-analysis of efficacy and safety of oral Chinese patent medicines combined with conventional western medicine in treatment of hypertension / 中国中药杂志

This study aims to systematically evaluate the effect of oral Chinese patent medicines on hypertension with network Meta-analysis. Randomized controlled trials on the treatment of hypertension with oral Chinese patent medicine combined with conventional western medicine were retrieved from China National Knowledge Infrastructure(CNKI), Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library(from establishment of the database to August 2021). Two researchers independently screened the articles, extracted the data, and evaluated article quality. Then R 4.1.0 was employed for data analysis. Finally, 195 eligible articles were screened out, involving 22 546 patients and 18 oral Chinese patent medicines. The results of the network Meta-analysis are as follows. In terms of reducing systolic blood pressure(SBP) and diastolic blood pressure(DBP), Xuesaitong, Qiangli Dingxuan Tablets, Songling Xuemaikang Capsules combined with conventional western medicine are superior. In improving blood lipids, the overall effects of Xinmaitong Capsules, Compound Xueshuantong Capsules, Ginkgo Folium preparations, Yindan Xinnaotong Soft Capsules, and Naoxintong Capsules combined with conventional western medicine are outstanding. In terms of regulating endothelial function, Yindan Xinnaotong Soft Capsules, Xinmaitong Capsules, Zhenju Jiangya Tablets, Compound Danshen Dripping Pills, Xuesaitong with conventional western medicine have certain advantages. As for the safety, the incidence of adverse reactions of conventional western medicine combined with oral Chinese patent medicines is lower than that of conventional western medicine alone. In summary, compared with conventional western medicine alone, the 18 oral Chinese patent medicines combined with conventional western medicine in the treatment of hypertension show advantages in improving blood pressure, blood lipids, and endothelial function. Among them, Xuesaitong, Qiangli Dingxuan Tablets, and Songling Xuemaikang Capsules may be the best oral Chinese patent medicines for lowering blood pressure. The conclusion needs to be further verified by more high-quality studies.

Clinical trials and evaluation of Chinese patent medicine for influenza / 中国中药杂志

The clinical randomized controlled trial(RCT) of Chinese patent medicine in the treatment of influenza were reviewed and analyzed to provide basic information for clinical decision and related research. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, and Cochrane Library were searched for RCTs of Chinese patent medicine for influenza published from database inception to July 25, 2021. The publication time, sample size, intervention and control measures, course of treatment, outcome indicators, and methodological quality of the trials were analyzed and evaluated. Ninety-two RCTs of Chinese patent medicine for influenza published between 2005 and 2021, were included, among which 17 RCTs(18.48%) had a sample size higher than 200 and the average sample size was about 145. Twenty-seven Chinese patent medicines were involved, including twenty-one oral medicines and six injections. The Chinese patent medicines in trials reported in more than five papers included Lianhua Qingwen Capsules/Gra-nules, Tanreqing Injection, and Reduning Injection. Fourteen intervention protocols were reported, of which Chinese patent medicine+western medicine+conventional treatment vs western medicine+conventional treatment(20.65%) was the most frequently employed. Additionally, 85.87% of the RCTs reported the course of treatment, and 80.43% of the RCTs determined 3-7 d as the intervention course. Forty-five outcome indicators were extracted, which were used 434 times, including symptoms/signs, physicochemical detection, safety events, TCM symptoms/syndromes, quality of life, long-term prognosis, and economic evaluation. Symptoms/signs(61.52%) exhibited the highest frequency. Methodological problems were prevalent in the included trials. The findings reveal that there are few clinical trials on influenza treatment by Chinese patent medicine, and the methodological problems are prominent, affec-ting the reliability and practicability of the trials. In the future research, the value characteristics of Chinese patent medicine should be highlighted and the quality control in the whole process should be strengthened based on the scientific and rigorous design.

Analysis of outcome indexes in randomized controlled trials of traditional Chinese medicine for rheumatic heart disease / 中国中药杂志

The present study analyzed the efficacy evaluation indexes of the randomized controlled trials(RCTs) of Chinese medi-cine in the treatment of rheumatic heart disease to lay the foundation for the construction of the corresponding core outcome index set. Clinical RCTs with a definite diagnosis of rheumatic heart disease were retrieved from CNKI, Wanfang, VIP, Sino Med, Pub Med, EMbase, and Cochrane Library from January 1, 2010, to December 31, 2020. Thirty-five RCTs were included, involving 3 314 patients and 41 efficacy evaluation indexes, which covered seven domains [traditional Chinese medicine(TCM) symptoms/syndromes, symp-toms/signs, physical and chemical examination, quality of life, long-term prognosis, economic evaluation, and safety events]. Physi-cal and chemical examination(56. 91%) and symptoms/signs(29. 27%) were the more frequently applied. The number of indexes used in a single trial ranged from 1 to 15, with an average of 4. The measurement time points of the top five indexes in the frequency of use were as follows: total response rate was reported at five measurement time points, ranging from 14 days to 6 months; left ventri-cular ejection fraction was measured at eight time points ranging from 5 days to 6 months; left ventricular end systolic diameter was measured at six time points, ranging from 5 days to 6 months; interleukin-2(IL-2) and tumor necrosis factor-α(TNF-α) were repor-ted 28 days after treatment. At present, there are many problems in the efficacy outcome indexes of RCTs in the treatment of rheumatic heart disease with TCM, such as large difference in quantity, unclear primary and secondary indexes, unreasonable selection of " surro-gate indexes", insufficient attention to long-term prognostic indexes and safety event indexes, non-standard application of composite in-dexes, long measurement period, and lack of TCM characteristics. It is urgent to establish the core outcome set for TCM treatment of rheumatic heart disease.

Objective To investigate the protective effect of Echinococcus granulosus hydatid cyst fluid protein (HCFP) on ovalbumin (OVA)-induced allergic rhinitis (AR) in mice. Methods Twenty-four BALB/c mice at ages of 8 to 10 weeks, each weighing approximately 20 g, were randomly divided into four groups, including groups A (blank control group), B (blank intervention group), C (AR model group) and D (AR+HCFP intervention group), with 6 mice in each group. On days 0, 2, 4, 6, 8, 10 and 12, mice in groups A, B, C and D were injected with 200 μL sterile phosphate buffered saline (PBS), 200 μL sterile PBS containing 20 μg HCFP, 200 μL sterile PBS containing 50 μg OVA and 5 mg Al(OH)3 gel, and 200 μL sterile PBS containing 50 μg OVA, 5 mg Al(OH)3 gel and 20 μg HCFP, respectively. On days 14 to 20, mice in groups A, B, C and D were administered with 40 μL sterile PBS, 40 μL sterile PBS containing 20 μg HCFP, 40 μL sterile PBS containing 2 mg OVA and 40 μL sterile PBS containing 2 mg OVA and 20 μL HCFP by nasal drop, respectively. Mouse behavioral changes were observed and behavioral scores were estimated. The serum levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), IL-5, IL-10, transforming growth factor-β (TGF-β) and OVA-specific IgE antibody (OVA-sIgE) were measured using enzyme-linked immunosorbent assay (ELISA), and the pathological changes of mouse nasal mucosa were observed by hematoxylin and eosin (HE) staining. Results The mean behavioral score was significantly greater in Group C (6.83 ± 0.50) than in groups A (1.17 ± 0.52) and B (1.33 ± 0.52) (P < 0.05), while a lower mean behavioral score was estimated in Group D (3.50 ± 0.50) than in Group C (P < 0.05). There were significant differences among the groups in terms of serum IFN-γ (F = 4.08, P < 0.05), IL-4 (F = 275.90, P < 0.05), IL-5 (F = 96.82, P < 0.05), IL-10 (F = 77.67, P < 0.05), TGF-β (F = 9.98, P < 0.05) and OVA-sIgE levels (F = 44.69, P < 0.05). The serum IFN-γ level was significantly lower in Group C than in groups A, B and C (P < 0.05), and the serum levels of IL-4, IL-5 and OVA-sIgE were significantly higher in Group C than in groups A, B and C (P < 0.05), while the serum IL-10 and TGF-β levels were significantly greater in Group D than in Group C (P < 0.05). Microscopy showed apparent loss of nasal mucosa cilia, increased number and enlargement of goblet cells, interstitial edema and submucous vascular dilation in Group C, while the pathological changes of nasal mucosa were alleviated in Group D relative to Group C. Conclusions E. granulosus HCFP has a protective activity against OVA-induced allergic rhinitis in mice.

Objective:To explore the antidepressant mechanism of Yinxing Mihuan oral solution （YMO） by investigating its effect on depression model rats. Method:The depression rats were induced by isolation combined with chronic unpredictable mild stress （CUMS） and then randomly divided into model group， fluoxetine group （10 mg·kg^-1） and high-dose （618 mg·kg^-1） and low-dose （309 mg·kg^-1） YMO groups. A blank control group was also set up and ten rats were included in each group. Modeling lasted for 21 consecutive days， and rats were administered the 8th day after stimulation at a dose of 10 mL·kg^-1 for 14 days， except those in the blank control and model groups which were given distilled water. Afterward， the sucrose preference test， open field test， tail suspension test were carried out. The pathological changes of hippocampus in depression rats were observed after hematoxylin-eosin （HE） staining. The content of interleukin-1<italic>β </italic>（IL-1<italic>β</italic>）， interleukin-6 （IL-6） and tumor necrosis factor-<italic>α </italic>（TNF-<italic>α</italic>） in the hippocampus of rats in each group and the expression of NOD-like receptor 3 （NLRP3） and other proteins in its related activation signaling pathways were detected with multi-factor detection （Luminex） and Western blot. Result:After 14 days of continuous administration， compared with the blank control group， the model group witnessed significantly reduced sugar water consumption rate and the times of rearing and significantly prolonged cumulative time of immobility during tail suspension （<italic>P</italic><0.05， <italic>P</italic><0.01）. Compared with the model group， the fluoxetine group and the high-dose YMO group saw increases in the times of rearing， times of crossing and sugar water consumption rate and a significant decrease in the cumulative time of immobility during tail suspension （<italic>P</italic><0.05， <italic>P</italic><0.01）. The results of HE staining showed that the neurons in the hippocampus of rats in the high-dose YMO group were arranged in order and slightly loosened， without obvious microglia infiltration observed. The levels of IL-1<italic>β</italic>， IL-6 and TNF-<italic>α</italic> in the hippocampus of the model group increased significantly as compared with the blank control group （<italic>P</italic><0.05， <italic>P</italic><0.01）， and their content in the high-dose YMO group was significantly lowered in the comparison with the model group （<italic>P</italic><0.05， <italic>P</italic><0.01）. Molecular biology experiments demonstrated that compared with the results of blank group， the expression of purinergic receptor P2X7 （P2RX7）， NLRP3， apoptosis-associated speck-like protein （ASC）， Caspase-1 and IL-1<italic>β</italic> remarkably increased in the model group （<italic>P</italic><0.05， <italic>P</italic><0.01）. Additionally， the expression of P2RX7， NLRP3， ASC， Caspase-1 and IL-1<italic>β </italic>was significantly inhibited in the fluoxetine group and the high-dose YMO group compared with the model group （<italic>P</italic><0.05， <italic>P</italic><0.01）. Conclusion:YMO can improve the depression-like behaviors of rats induced by isolation combined with CUMS， and its mechanism of action is related to the regulation of the P2RX7/NLRP3 signaling pathway.

Objective:To explore the intervention effect of Wenxin granule on endoplasmic reticulum stress apoptosis pathway and its related mechanism in rats with myocardial infarction. Method:Ligating the left anterior descending coronary artery to establish the rat model， the rats were randomly divided into 5 groups， namely sham group， model group， betaloc group and low， high-dose Wenxin granule groups，10 in each group. The sham group and the model group were given 10 mL∙kg^-1∙d^-1 deionized water， the low， high-dose modified Wenxin groups were given 1.35， 2.7 g∙kg^-1∙d^-1 aqueous solution respectively， and the betaloc group was given 2.25 mg∙kg^-1∙d^-1 aqueous solution. After 14 days，the catheter method was used to detect the cardiac hemodynamics and hematoxylin-eosin staining （HE） was used to observe the pathological morphological changes. The levels of endoplasmic reticulum stress protein glucose regulatory protein 78（GRP78）， protein kinase R like endoplasmic reticulum kinase（PERK）， phosphorylated activated PERK（p-PERK）， activated transcription factor 6 （ATF6）， nuclear transcription factor X cassette binding protein（XBP1） and apoptosis protein C/EBP homologous protein（CHOP）， B cell lymphoma/leukemia-2（Bcl-2） and Bcl-2 associated X protein（Bax） were detected by Western blot. Deoxyribonucleotide end-transferase-mediated notch end labeling （TUNEL） was also used to detect the myocardial cell apoptosis. Result:Compared with control group， the levels of the maximum ascending rate of left ventricular pressure（+dp/dt_max）， the maximum descending rate of left ventricular pressure（-dp/dt_max） and the left ventricular systolic blood pressure（LVSP） were decreased significantly（<italic>P</italic><0.05），but the level of the left ventricular end diastolic blood pressure （LVEDP） was significantly increased（<italic>P</italic><0.05）. The expressions of GRP78， p-PERK， PERK， ATF6， XBP1， CHOP， Bax and apoptosis index were increased significantly （<italic>P</italic><0.05，<italic>P</italic><0.01）， while Bcl-2/Bax and Bcl-2 were decreased significantly（<italic>P</italic><0.01） in model group. Compared with the model group， the levels of -dp/dt_max and Bcl-2 were increased significantly （<italic>P</italic><0.05），while the level of the apoptosis index was decreased significantly（<italic>P</italic><0.01） in low-dose Wenxin granule group. In high-dose Wenxin granule group， the levels of +dp/dt_max and -dp/dt_max were increased significantly（<italic>P</italic><0.05，<italic>P</italic><0.01）， the levels of endoplasmic reticulum stress pathway protein GRP78， p-PERK， PERK， ATF6， XBP1，apoptosis-related protein CHOP， Bax and apoptosis index were decreased significantly（<italic>P</italic><0.01）， but Bcl-2 and Bcl-2/Bax were increased significantly （<italic>P</italic><0.01）. Conclusion:Wenxin granule has effect in inhibiting excessive endoplasmic reticulum stress， reducing myocardial cell apoptosis and improving cardiac hemodynamics. Its molecular mechanism may be related to decrease the levels of GRP78， PERK， p-PERK， ATF6， XBP1， CHOP， Bax and increasing the expression of Bcl-2.

Analysis of components of proteins from Echinococcus granulosus cyst fluid / 中国血吸虫病防治杂志

Objective To analyze the components of proteins from Echinococcus granulosus cyst fluid using the shotgun method, and to identify the active components with potential regulatory effects for immune dysregulation diseases. Methods The E. granulosus cyst fluid was collected aseptically from the hepatic cysts of patients with cystic echinococcosis, and characterized by liquid chromatography (LC) tandem mass spectrometry (MS/MS) following digestion with trypsin. The protein data were searched using the software MaxQuant version 1.6.1.0 and the cellular components, molecular functions, and biological processes of the identified proteins were analyzed using the Gene Ontology (GO) method. Results The E. granulosus cyst fluid separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) had a relative molecular mass of 25 to 70 kDa. LS-MS/MS analysis identified 37 proteins, including 32 known proteins and 5 unknown proteins. At least 4 proteins were preliminarily found to exhibit potential regulatory effects for immune dysregulation diseases, including antigen B, glutathione-S-transferase (GST), thioredoxin peroxidase (TPX) and malate dehydrogenase (MDH). GO enrichment analysis showed that the identified proteins had 149 molecular functions and were involved in 341 biological processes. Conclusions E. granulosus cyst fluid has a variety of protein components, and four known proteins are preliminarily identified to be associated with immune dysregulation diseases.

The progress on the relationship between P2X7 receptor and pancreatic cancer / 医学研究生学报

Pancreatic cancer is one of the cancers with poor prognosis at present, which has high resistance to various anti-tumor drugs as a result of the interaction among pancreatic cancer cells, cancer stem cells, and the tumor microenvironment. P2X7 receptors are extracellular adenosine triphosphate(ATP)-gated nonselective cation channels, which have many biological functions including being involved in cell signal transduction and cytokine secretion, mediate cell survival and growth. Studies have shown that P2X7 receptor is highly expressed in pancreatic cancer and promotes the proliferation, migration and invasion of pancreatic cancer cells by supporting proliferation of pancreatic stellate cells and regulating the expressed of the MMP2/MMP9 protein. The paper reviews the recent research advances of P2X7 receptor in pancreatic cancer.

Epidemiology, diagnosis, treatment and control measures of trichinellosis in China: an overview / 中国血吸虫病防治杂志

Trichinellosis is a worldwide zoonotic parasitic disease, which may infect humans and a wide range of animals, including carnivores, herbivores and even birds. Humans get infections through ingestion of raw or semi-cooked meat or meat products containing live Trichinella larvae. Currently, this zoonosis is predominantly prevalent in southwestern, northeastern and central parts of China, which poses a great threat to human health and socioeconomic development. In addition, the emergent public health hazards caused by trichinellosis outbreaks greatly threaten human health and social stability. This review describes the current status, diagnosis, treatment and control measures of trichinellosis in China, so as to provide insights into trichinellosis control in the country.

Protective effect of recombinant adult serine protease inhibitor from Trichinella spiralis on sepsis-associated acute kidney injury in mice / 中国血吸虫病防治杂志

Objective To investigate the protective effect of recombinant adult serine protease inhibitor from Trichinella spiralis (TsadSPI) on sepsis-associated acute kidney injury in mice. Methods A total of 18 male BALB/c mice were randomly divided into the sham-operation group, the model group, and the TsadSPI treatment group, of 6 mice in each group. Sepsis-associated acute kidney injury was modeled in the model group and TsadSPI treatment group by cecal ligation puncture (CLP), while mice in the sham-operation group were only given exploratory laparotomy without ligation or perforation of the cecum. After 30 min of CLP, mice in the sham-operation group and the model group were intraperitoneally injected with PBS (100 μL), and mice in the TsadSPI treatment group were intraperitoneally injected with PBS (100 μL) containing TsadSPI (2 μg). At 12 h following modeling, the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and urea nitrogen (BUN) were measured to assess the liver and kidney functions, and the changes of the mouse kidney structure were observed using HE staining. In addition, the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10 and transforming growth factor (TGF)-β were measured using an enzyme-linked immunosorbent assay (ELISA), and the myeloid differentiation factor 88 (MyD88) and nuclear factor kappa-B (NF-κB) p65 expression was determined in kidney tissues using immunohistochemical staining. Results At 12 h following CLP, there were significant differences in the serum levels of ALT (F = 41.031, P < 0.001), AST (F = 54.757, P < 0.001), Cr (F = 24.142, P < 0.001) and BUN (F = 214.849, P < 0.001) among the three groups, and higher levels of ALT, AST, Cr and BUN were measured in model group than in the sham-operation group (P < 0.001), while lower ALT, AST, Cr and BUN levels were found in the TsadSPI treatment group than in the model group (P < 0.001). HE staining showed severe mouse kidney injuries following CLP, and TsadSPI treatment resulted in remarkable alleviation of the injury. ELISA measured significant differences in the TNF-α (F = 47.502, P < 0.001) and IL-6 levels (F = 222.061, P < 0.001) among the three groups, and showed a remarkable reduction in the TNF-α and IL-6 levels in the TsadSPI treatment group as compared to those in the model group (P < 0.001). In addition, there were significant differences in serum IL-10 (F = 16.227, P < 0.001) and TGF-β levels (F = 52.092, P < 0.001) among the three groups, and higher IL-10 and TGF-β levels were seen in the TsadSPI treatment group than in the model group (P < 0.001). Immunohistochemical staining showed greater MyD88 expression and a higher nuclear positive rate of NF-κB p65 in kidney tissues in the model group than in the TsadSPI treatment group. Conclusions TsadSPI may reduce the MyD88 expression and nuclear positive rate of NF-κB p65 in mouse kidney tissues to up-regulate the expression of immunomodulatory factors and down-regulate the expression of pro-inflammatory cytokines, thereby protecting sepsis-associated acute kidney injury.

Polarization of bone marrow-derived macrophages induced by recombinant Trichinella spiralis cysteine protease inhibitors in vitro / 中国血吸虫病防治杂志

Objective To investigate the regulatory role of recombinant Trichinella spiralis cysteine protease inhibitors (rTs-Cys) in induction of polarization of bone marrow-derived macrophages (BMDMs) in vitro. Methods BMDMs were captured and cultured in conditioned medium for 7 days. Then, mature BMDMs were harvested and assigned into four groups. Cells in Group A (negative control) were given 10 ng/mL IFN-γ combined with 100 ng/mL LPS, cells in Group B (positive control) were treated with IL-4 and IL-10 (at 10 ng/mL both), and cells in Group C (recombinant protein alone) were stimulated with 1 μg/mL rTs-Cys, while cells in Group D (protein co-culture) were simultaneously treated with 1 μg/mL rTs-Cys, 10 ng/mL IFN-γ and 100 ng/mL LPS. Cells and culture supernatant were collected 24 hour post-treatment, and the proportions of F4/80+, CD11b+, CD206+ and CD11c+ cells were detected by flow cytometry. The levels of interleukin IL-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-10 and transforming growth factor-β (TGF-β) in the cell culture supernatant were measured by ELISA and the CD86+ and CD206+ phenotypes were identified by immunofluorescent staining. Results Flow cytometry detected no significant difference in the proportion of F4/80+ CD11b+ CD11c+ cells among the four groups (F = 46.184, P < 0.001), and a lower proportion of F4/80+ CD11b+ CD11c+ cells was seen in groups C and D than in group A (all P values < 0.001). There was a significant difference in the proportion of F4/80+ CD11b+ CD206+ cells among the four groups (F = 11.032, P < 0.001), and a greater proportion of F4/80+ CD11b+ CD206+ cells was seen in groups C and D than in group A (all P values < 0.01). Immunofluorescent staining showed higher CD206+ expression and lower CD86+ expression in groups C and D than in Group A. There were significant differences in the IL-6 and (F = 3.950, P < 0.001) and TNF-α (F = 205.827, P < 0.001) levels in the cell culture supernatants among the four groups, and significantly lower IL-6 and TNF-α levels were measured in groups C and D than in Group A (both P < 0.05). There were significant differences in the IL-10 and (F = 8.274, P < 0.001) and TGF-β (F = 13.559, P < 0.01) levels in the cell culture supernatants among the four groups, and greater IL-10 and TGF-β levels were measured in Group C than in Group A (both P values < 0.01). In addition, the TGF-β level was significantly higher in Group D than in Group A (P < 0.05); however, there was no significant difference in the IL-10 level between groups D and A (P > 0.05). Conclusion rTs-Cys may induce the polarization of BMDMs to antiinflammatory M2 macrophages in vitro and inhibit the activation of M1 macrophages.

OBJECTIVE@#To observe the effect of electronic moxibustion on memory function in the patients with amnestic mild cognitive impairment (aMCI).@*METHODS@#A total of 59 aMCI patients were randomized into an electronic moxibustion group (30 cases) and a placebo moxibustion group (29 cases). In the electronic moxibustion group, the electronic moxibustion was applied to Baihui (GV 20), Dazhui (GV 14), Mingmen (GV 4) and Taixi (KI 3), 45 ℃ in temperature, 20 min each time. The treatment was given once a day, 5 times a week. The treatment for 4 weeks was as one course and 2 courses were required totally. In the placebo moxibustion group, the moxa-free patch was used, 38 ℃ in temperature. The acupoint selection and the treatment frequency were same as the electronic moxibustion group. Before and after treatment, Rivermead behavior memory test (RBMT) was adopted to evaluate the global memory function of the patients in the two groups and the N-back task test was adopted to evaluate working memory function separately. Additionally, the mini-mental state examination (MMSE) and its immediate memory, Montreal cognitive assessment (MoCA) and its delay recall were adopted to evaluate the global cognitive function and memory function@*RESULTS@#In the electronic moxibustion group, after treatment, RBMT score, N-back accuracy rates, MMSE and MoCA scores and the scores of immediate memory and delay recall were improved significantly as compared with those before treatment (<0.01). In the placebo moxibustion group, the accuracy rates of 1-back and 2-back task and the scores of immediate memory and delay recall were improved obviously as compared with those before treatment (<0.05, <0.01). After treatment, the improvements of RBMT score, the accuracy rates of N-back task and MMSE and MoCA scores in the electronic moxibustion group were higher than those in the placebo moxibustion group (<0.05).@*CONCLUSION@#Electronic moxibustion improves memory function in the patients with amnestic mild cognitive impairment.

Cell death of intestinal epithelial cells in intestinal diseases / 生理学报

Gut injury continues to be the devastating and unpredictable critical illness associated with increased cell death of intestinal epithelial cells (IECs). The IECs, immune system and microbiome are the interrelated entities to maintain normal intestinal homeostasis and barrier integrity. In response to microbial invasion, IEC cell death occurs to maintain intestinal epithelium function and retain the continuous renewal and tissue homeostasis. But the imbalance of IEC cell death results in increased intestinal permeability and barrier dysfunction that leads to several acute and chronic intestinal diseases, such as intestinal ischemia/reperfusion (I/R), sepsis, inflammatory bowel diseases (IBD), necrotizing enterocolitis (NEC), etc. During the pathophysiological state, the excessive IEC apoptotic cell death leads to a chronic inflammatory condition, later switches to necroptotic cell death mechanism that induces more pathological features than apoptosis and may also induce other lytic cell death mechanisms like pyroptosis and ferroptosis to increase the pathogenesis of the intestinal diseases. But still, there remains gaps in the fundamental knowledge about the IEC cell death mechanisms in chronic intestinal diseases. Together, a deep understanding of the specific cell death mechanisms underlying chronic intestinal diseases, including sepsis, IBD, NEC, and intestinal I/R, is desperately needed to develop emerging novel promising therapeutic strategies. This review aims to show how the acute and critical illness in the gut are driven by IEC cell death mechanism, such as apoptosis, necrosis, necroptosis, pyroptosis, and ferroptosis.
