AIM:To observe the accuracy of infiltrating B ultrasound guided A-scan segment biometric measurement of axial length in dense cataract.METHODS: Perspective study. A total of 86 patients(90 eyes)with dense cataract were selected from Chengdu Aier Eye Hospital from August 2020 to August 2022. There were 61 males(59 eyes)males and 25 females(31 eyes)females, with an average age of 66.49±14.55 years. The axial length(AL), anterior chamber depth(ACD)(including corneal thickness), corneal curvature(K), lens thickness(LT), central corneal thickness(CCT), and white-to-white(WTW)were measured preoperatively by contact A-scan, infiltrating B ultrasound guided segmented A-scan, and IOL Master 700, respectively. At 1 wk postoperatively, AL was retested by IOL Master 700 in aphakic mode. Furthermore, the agreements and correlations of AL obtained by the three kinds of devices were analyzed.RESULTS:The AL measured by contact A-scan and infiltrating B ultrasound guided segmented A-scan were 23.40(22.63, 23.89)mm and 23.70(23.04, 24.25)mm, respectively, and the AL measured by IOL Master 700 at 1 wk postoperatively was 23.72(23.01, 24.27)mm. There were statistical significant difference in AL measured by the three methods(P=0.018), while there were no statistical significant difference in AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700(P=0.991). Bland-Altman analysis showed that there was a good agreement in AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700(P=0.0809). The AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700 was positively correlated(rs=0.992, P<0.0001), and the AL was positively correlated between preoperative contact A-scan and postoperative IOL Master 700(rs=0.989, P<0.0001).CONCLUSION:For dense cataract, infiltrating B ultrasound guided A-scan segment biometric measurement, which has good correlations and agreement, is closer to the AL measured by IOL Master 700 postoperatively than that measured by contact A-scan.
摘要
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting both upper and lower motor neurons. ALS patients develop progressive muscle atrophy, muscle weak and paralysis, finally died of respiratory failure. ALS is characterized by fast aggression and high mortality. What' s more, the disease is highly heterogeneous with unclear pathogenesis and lacks effective drugs for therapy. In this review, we summarize the main pathological mechanisms and the current drugs under development for ALS, which may provide a reference for the drug discovery in the future.
摘要
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons (MNs) with large unmet medical needs. Multiple pathological mechanisms are considered to contribute to the progression of ALS, including neuronal oxidative stress and mitochondrial dysfunction. Honokiol (HNK) has been reported to exert therapeutic effects in several neurologic disease models including ischemia stroke, Alzheimer's disease and Parkinson's disease. Here we found that honokiol also exhibited protective effects in ALS disease models both in vitro and in vivo. Honokiol improved the viability of NSC-34 motor neuron-like cells that expressed the mutant G93A SOD1 proteins (SOD1-G93A cells for short). Mechanistical studies revealed that honokiol alleviated cellular oxidative stress by enhancing glutathione (GSH) synthesis and activating the nuclear factor erythroid 2-related factor 2 (NRF2)-antioxidant response element (ARE) pathway. Also, honokiol improved both mitochondrial function and morphology via fine-tuning mitochondrial dynamics in SOD1-G93A cells. Importantly, honokiol extended the lifespan of the SOD1-G93A transgenic mice and improved the motor function. The improvement of antioxidant capacity and mitochondrial function was further confirmed in the spinal cord and gastrocnemius muscle in mice. Overall, honokiol showed promising preclinical potential as a multiple target drug for ALS treatment.

Objective To explore the improvements of high-fat intake on lung injury induced by Paragonimus proliferus infection in rats, and to preliminarily explore the mechanisms underlying the role of cytochrome P450 4A1 (CYP 4A1) in the improve ments. Methods SD rats were randomly assigned into three groups, including the normal control group (n = 10), the infection and normal diet group (n = 12) and the infection and high-fat diet group (n = 12). Rats in the normal control group were fed with normal diet and without any other treatments, and animals in the infection and normal diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with normal diet, while rats in the infection and high-fat diet group were subcutaneously injected with 8 excysted metacercariae of P. proliferus via the abdominal wall, followed by feeding with high-fat diet. All rats were sacrificed 28 weeks post-infection, and serum samples and lung specimens were collected. Following hematoxylin-eosin (HE) staining of rat lung specimens, the rat lung injury was observed under an optical microscope, and alveolitis was evaluated using semi-quantitative scoring. Serum interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNF-α) levels were measured using enzyme-linked immunosorbent assay (ELISA), and the cytochrome P450 4A1 (CYP 4A1) expression was quantified in rat lung specimens at transcriptional and translational levels using quantitative real-time PCR (qPCR) and Western blotting assays. Results Alveolar wall thickening, edema and inflammatory cell infiltration were alleviated 28 weeks post-infection with P. proliferus in rats in the infection and high-fat diet group relative to the infection and normal diet group, and no alveolar consolidation was seen in the infection and high-fat diet group. The semi-quantitative score of alveolitis was significantly higher in the infection and normal diet group [(2.200 ± 0.289) points] than in the normal control group [(0.300 ± 0.083) points] and the infection and high-fat diet group [(1.300 ± 0.475) points] (both P values < 0.05), and higher serum IL-1β [(151.586 ± 20.492)] pg/mL and TNF-α levels [(180.207 ± 23.379) pg/mL] were detected in the infection and normal diet group than in the normal control group [IL-1β: (103.226 ± 3.366) pg/mL; TNF-α: (144.807 ± 1.348) pg/mL] and the infection and high-fat diet group [IL-1β: (110.131 ± 12.946) pg/mL; TNF-α: (131.764 ± 27.831) pg/mL] (all P values < 0.05). In addition, lower CYP 4A1 mRNA (3.00 ± 0.81) and protein expression (0.40 ± 0.02) was quantified in lung specimens in the infection and normal diet group than in the normal control group [(5.03 ± 2.05) and (0.84 ± 0.14)] and the infection and high-fat diet group [(11.19 ± 3.51) and (0.68 ± 0.18)] (all P values < 0.05). Conclusion High-fat intake may alleviate lung injuries caused by P. proliferus infection in rats through up-regulating CYP 4A1 expression in lung tissues at both translational and transcriptional levels.

摘要
Stroke is one of the most common cerebrovascular diseases， including hemorrhagic stroke and ischemic stroke. From a modern medical perspective， stroke is caused by cerebrovascular damage or embolism leading to impaired blood circulation. From the traditional Chinese medicine （TCM） perspective， the pathogenesis of this disease is mainly due to the disorder of Qi and blood， which ascend to the brain， causing either blood extravasation or blockage of brain collaterals. Stasis is a pathological factor that runs throughout the entire course of stroke， and the method of promoting blood circulation and resolving stasis has been a core treatment for stroke for a long time. Hirudo， as a traditional insect drug， has shown good effects in promoting blood circulation and resolving stasis. Modern pharmacological research has confirmed that Hirudo contains anticoagulant components， which provide significant advantages in dissolving thrombi in ischemic stroke and facilitating hematoma absorption in hemorrhagic stroke. Hirudo and its related preparations have been proven to exert an anti-stroke effect through anticoagulation， anti-thrombosis， and protection of vascular endothelium. As a result， they have been widely used in the treatment of stroke. This article explored the theoretical basis and research status of using Hirudo for treating stroke based on its main active components and hemostatic properties and summarized the current research status of commonly used Hirudo-based formulations and preparations， aiming to provide references for the involvement of Hirudo in stroke treatment.

OBJECTIVE To compare the change law of multi-components in the extraction process between Liuwei dihuang powder decoction pieces and traditional decoction pieces （hereinafter referred to as powder decoction pieces and traditional decoction pieces）， and to provide scientific basis for the modern technology research of Liuwei dihuang formula. METHODS Taking powder decoction pieces and traditional decoction pieces as samples， the samples were taken when soaking for 60 min， at 0， 5， 10， 15， 20， 25， 30， 40， 50， 60 min of the first decocting and at 5， 10， 20， 30， 40 min of the second decocting， respectively. HPLC method was used to establish the fingerprints of 2 kinds of decoction pieces with different decocting time. The similarity evaluation and peak identification were performed. The contents of 8 components including 5-hydroxyfurfural， catechin， monoglycoside， loganin， swertin glycoside， dihydroquercetin， paeonol and benzoyl paeoniflorin were all determined. RESULTS With different decocting time， the similarties between 2 kinds of decoction pieces and their respective control fingerprints R were all greater than 0.98. In the fingerprints of traditional decoction pieces， five chromatographic peaks were identified， namely， 5- hydroxyfurfural， monetin， swertiaoside， dihydroquercetin and paeonol； in the fingerprints of powder decoction pieces， six chromatographic peaks were identified， namely， 5-hydroxyfurfural， monoglycoside， swertiamarin， dihydroquercetin， paeonol and benzoyl paeoniflorin. The results of content determination showed that in the first 5 minutes of the first decocting， the decocting rate of almost all the ingredients in the powder decoction pieces was faster than that of the traditional decoction pieces； after 40 min， the contents of other active ingredients were lower than those of traditional decoction pieces except for 5-hydroxyfurfural and paeonol. In the process of second decocting， except for paeonol and loganin， the contents of other ingredients in powder decoction pieces were higher than that in traditional decoction pieces； catechin was completely decocted from the traditional decoction pieces in the first decocting， while it could still be detected in the powder decoction pieces in the second decocting. There was little difference in the total decocted amount of the 8 ingredients in the two decoction pieces. CONCLUSIONS The chemical composition of powder decoction pieces of Liuwei dihuang formula has no obvious advantages compared with traditional decoction pieces， and can not save the decocting time and the amount of medicinal materials.
摘要
Bibenzyls, a kind of important plant polyphenols, have attracted growing attention for their broad and remarkable pharmacological activities. However, due to the low abundance in nature, uncontrollable and environmentally unfriendly chemical synthesis processes, these compounds are not readily accessible. Herein, one high-yield bibenzyl backbone-producing Escherichia coli strain was constructed by using a highly active and substrate-promiscuous bibenzyl synthase identified from Dendrobium officinale in combination with starter and extender biosynthetic enzymes. Three types of efficiently post-modifying modular strains were engineered by employing methyltransferases, prenyltransferase, and glycosyltransferase with high activity and substrate tolerance together with their corresponding donor biosynthetic modules. Structurally different bibenzyl derivatives were tandemly and/or divergently synthesized by co-culture engineering in various combination modes. Especially, a prenylated bibenzyl derivative ( 12) was found to be an antioxidant that exhibited potent neuroprotective activity in the cellular and rat models of ischemia stroke. RNA-seq, quantitative RT-PCR, and Western-blot analysis demonstrated that 12 could up-regulate the expression level of an apoptosis-inducing factor, mitochondria associated 3 (Aifm3), suggesting that Aifm3 might be a new target in ischemic stroke therapy. This study provides a flexible plug-and-play strategy for the easy-to-implement synthesis of structurally diverse bibenzyls through a modular co-culture engineering pipeline for drug discovery.
摘要
Tolerogenic dendritic cells (tolDCs) facilitate the suppression of autoimmune responses by differentiating regulatory T cells (Treg). The dysfunction of immunotolerance results in the development of autoimmune diseases, such as rheumatoid arthritis (RA). As multipotent progenitor cells, mesenchymal stem cells (MSCs), can regulate dendritic cells (DCs) to restore their immunosuppressive function and prevent disease development. However, the underlying mechanisms of MSCs in regulating DCs still need to be better defined. Simultaneously, the delivery system for MSCs also influences their function. Herein, MSCs are encapsulated in alginate hydrogel to improve cell survival and retention in situ, maximizing efficacy in vivo. The three-dimensional co-culture of encapsulated MSCs with DCs demonstrates that MSCs can inhibit the maturation of DCs and the secretion of pro-inflammatory cytokines. In the collagen-induced arthritis (CIA) mice model, alginate hydrogel encapsulated MSCs induce a significantly higher expression of CD39+CD73+ on MSCs. These enzymes hydrolyze ATP to adenosine and activate A2A/2B receptors on immature DCs, further promoting the phenotypic transformation of DCs to tolDCs and regulating naïve T cells to Tregs. Therefore, encapsulated MSCs obviously alleviate the inflammatory response and prevent CIA progression. This finding clarifies the mechanism of MSCs-DCs crosstalk in eliciting the immunosuppression effect and provides insights into hydrogel-promoted stem cell therapy for autoimmune diseases.

OBJECTIVE@#To compare the short-term clinical efficacy and radiologic differences between oblique lateral interbody fusion(OLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for degenerative lumbar spondylolisthesis.@*METHODS@#A retrospective analysis was performed on 58 patients with lumbar spondylolisthesis treated with OLIF or MIS-TLIF from April 2019 to October 2020. Among them, 28 patients were treated with OLIF (OLIF group), including 15 males and 13 females aged 47 to 84 years old with an average age of (63.00±9.38) years. The other 30 patients were treated with MIS-TLIF(MIS-TLIF group), including 17 males and 13 females aged 43 to 78 years old with an average age of (61.13±11.10) years. General conditions, including operation time, intraoperative blood loss, postoperative drainage, complications, lying in bed, and hospitalization time were recorded in both groups. Radiological characteristics, including intervertebral disc height (DH), intervertebral foramen height (FH), and lumbar lordosis angle (LLA), were compared between two groups. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate the clinical effect.@*RESULTS@#The operation time, intraoperative blood loss, postoperative drainage, lying in bed, and hospitalization time in OLIF group were significantly less than those in the MIS-TLIF group (P<0.05). The intervertebral disc height and intervertebral foramen height were significantly improved in both groups after the operation (P<0.05). The lumbar lordosis angle in OLIF group was significantly improved compared to before the operation(P<0.05), but there was no significant difference in the MIS-TLIF group before and after operation(P>0.05). Postoperative intervertebral disc height, intervertebral foramen height, and lumbar lordosis were better in the OLIF group than in the MIS-TLIF group (P<0.05). The VAS and ODI of the OLIF group were lower than those of the MIS-TLIF group within 1 week and 1 month after the operation (P<0.05), and there were no significant differences in VAS and ODI at 3 and 6 months after the operation between the two groups(P>0.05). In the OLIF group, 1 case had paresthesia of the left lower extremity with flexion-hip weakness and 1 case had a collapse of the endplate after the operation;in the MIS-TLIF group, 2 cases had radiation pain of lower extremities after decompression.@*CONCLUSION@#Compared with MIS-TLIF, OLIF results in less operative trauma, faster recovery, and better imaging performance after lumbar spine surgery.

Objective To analyze the effect of body mass index (BMI) on pulmonary function and quality of life in elderly patients with chronic obstructive pulmonary disease (COPD), and to provide theoretical basis for the diagnosis and treatment of COPD. Methods A total of 1 278 patients who visited the respiratory department of our hospital from January 2019 to June 2022 were selected as the research objects, including 368 COPD patients, 225 of whom were in stable stage and 143 of whom were in acute exacerbation stage. According to BMI, they were divided into low group (n=31, BMI2), normal group (n=198,18.5kg/m2≤BMI2), overweight group (n=106, 24kg/m2≤BMI2) and obese group (n=33,BMI≥28 kg/m2). Health-related quality of life (HRQOL) was used to evaluate the quality of life of patients. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1/FVC were measured by pulmonary function instrument to evaluate the pulmonary function grade of patients. Logistic regression was used to analyze the risk factors of pulmonary function and quality of life in COPD patients. Results There were significant differences in age, smoking, BMI and hyperlipidemia between stable COPD patients and acute exacerbation COPD patients with different BMI groups (P<0.05). There were significant differences in the proportion of pulmonary function Ⅲ/Ⅳ, FEV1/FVC, FEV1pred and HRQOL scores among different BMI groups (P<0.05) . The FEV1/FVC and FEV1pred in patients with acute exacerbation and stable COPD from high to low were obese group, overrecombination group, normal group and too low group, and the differences were statistically significant (P<0.05). The HRQOL scores of COPD patients in acute exacerbation and stable stage from high to low were obese group, overweight group, normal group and too low group, and the difference was statistically significant (P<0.05). Low body mass index was a risk factor for pulmonary function in COPD patients at stable stage (OR=2.52) and acute exacerbation stage (OR=2.83) (P<0.05). High body mass index was a risk factor for quality of life in patients with stable COPD (OR=2.43) and acute exacerbation (OR=2.65) (P<0.05). Conclusion BMI can affect pulmonary function and quality of life in COPD patients. Patients should maintain normal BMI, which can improve pulmonary function and quality of life.

Objective: To investigate the effect of sugammadex on postoperative nausea and vomiting(PONV) after intracranial aneurysm surgery. Methods: Data from intracranial aneurysms patients who met the inclusion and exclusion criteria and underwent interventional surgery in the Department of Neurosurgery, Peking University International Hospital from January 2020 to March 2021 were prospectively included. According to the random number table method, the patients were divided by 1∶1 into the neostigmine+atropine group (group N) and the sugammadex group (group S). Use an acceleration muscle relaxation monitor for muscle relaxation monitoring, and administer neostigmine+atropine and sugammadex to block residual muscle relaxation drugs after surgery. The incidence rates of PONV and severity, the appearance of anesthesia, and the correlation between PONV and postoperative complications were recorded in both groups during five periods after surgery: 0-0.5 hours (T1),>0.5-2.0 hours(T2),>2.0-6.0 hours (T3),>6.0-12.0 hours (T4) and >12.0-24.0 hours (T5). Group comparisons of quantitative data were performed by the independent sample t-test, and categorical data was performed by the χ2 or rank sum test. Results: A total of 66 patients were included in the study, including 37 males and 29 female, aged (59.3±15.4) years (range: 18 to 77 years). The incidence rates of PONV of 33 patients in group S at different time periods of T1, T2, T3, T4, and T5 after surgery were respectively 27.3%(9/33),30.3%(10/33),12.1%(4/33),3.0%(1/33),0(0/33),and the incidence rates of PONV of 33 patients in the group N at different time periods of T1, T2, T3, T4 and T5 after surgery were respectively 36.4%(12/33),36.4%(12/33),33.3%(11/33),6.1%(2/33) and 0(0/33).The incidence of PONV was lower in the group S only in the T3 period after reversal than in the group N (χ2=4.227, P=0.040).However, there was no statistically significant difference in the incidence of PONV between the two groups of patients in other periods (all P>0.05). The recovery time for spontaneous breathing in patients in group S was (7.7±1.4) minutes, the extubation time was (12.4±5.3) minutes, and the safe exit time for anesthesia recovery was (12.3±3.4) minutes; the N groups were (13.9±2.0) minutes, (18.2±6.0) minutes, and (18.6±5.2) minutes, respectively; three time periods in group S were shorter than those in group N, and the differences were statistically significant (all P<0.05). The results regarding the occurrence of complications in patients with different levels of PONV at different time intervals after surgery in the two groups were as follows: in the T3 time period of group N, a significant difference was observed only in the occurrence of postoperative complications among patients with different levels of PONV (χ2=24.786, P<0.01). However, in the T4 time period, significant differences were found in the occurrence of postoperative complications among both the same level and different level PONV patients (χ2=15.435, 15.435, both P<0.01). Significant differences were also observed in the occurrence of postoperative complications among the same level and different level PONV patients in both the T3 and T4 time periods of group S (all P<0.01). Conclusion: Sugammadex can be used to reverse muscle relaxation in patients undergoing intracranial aneurysm intervention surgery,and it does not have a significant impact on the incidence of PONV, it can also optimize the quality of anesthesia recovery and reduce the incidence of complications after intracranial aneurysm embolization surgery.

Objective·To investigate the anesthetic effect of PetCO2 monitoring nasopharyngeal airway on preventing hypoxia in patients with obstructive sleep apnea syndrome(OSAS)during magnifying endoscopy.Methods·Eighty OSAS patients who underwent magnifying endoscopy anesthesia in Xuchang Central Hospital of Henan Province from February to June 2023 were randomly divided into PetCO2 monitoring nasopharyngeal airway group(group T)and traditional nasopharyngeal airway group(group B),with 40 cases in each group.General information,perioperative data and total anesthetic dosage of the two groups of patients were collected and compared.The systolic blood pressure(SBP),diastolic blood pressure(DBP),heart rate(HR)and pulse oxygen saturation(SpO2)of the two groups of patients before anesthesia(T0),at the time of entering the endoscopy(T1),3 min after entering the endoscopy(T2),10 min after entering the endoscopy(T3)and at the end of endoscopy(T4)were observed and recorded,respectively.The incidence of body movement and hypoxemia,and the effects of preventing hypoxia(including mask ventilation,jaw-lift support and chest compressions to assist breath)of the two groups of patients were recorded.Results·There were no significant differences in general information,perioperative data and total anesthetic dosage between the two groups.At T1 and T2,SpO2 in group T was higher than that in group B(T1:P=0.041,T2:P=0.012),and there was no statistically significant difference in SBP,DBP and HR between the groups;at other time points,there was no statistically significant difference in the four indicators between the two groups.Compared with group B,the incidences of body movement,hypoxemia,mask ventilation,jaw-lift support and chest compressions to assist breath in group T were all decreased(all P=0.000).Conclusion·PetCO2 monitoring nasopharyngeal airway can reduce the incidence of hypoxia during magnifying endoscopy in patients with OSAS,with minimal adverse events.Also,it can detect the status of lung ventilation in time,guide clinical intervention,reduce complications and improve the safety of magnifying endoscopy anesthesia.
