RESUMO

γδ T cells are a kind of innate immune T cell. They have not attracted sufficient attention because they account for only a small proportion of all immune cells, and many basic factors related to these cells remain unclear. However, in recent years, with the rapid development of tumor immunotherapy, γδ T cells have attracted increasing attention because of their ability to exert cytotoxic effects on most tumor cells without major histocompatibility complex (MHC) restriction. An increasing number of basic studies have focused on the development, antigen recognition, activation, and antitumor immune response of γδ T cells. Additionally, γδ T cell-based immunotherapeutic strategies are being developed, and the number of clinical trials investigating such strategies is increasing. This review mainly summarizes the progress of basic research and the clinical application of γδ T cells in tumor immunotherapy to provide a theoretical basis for further the development of γδ T cell-based strategies in the future.

RESUMO

ObjectiveTo observe the effects of electroacupuncture at Zhongwan (CV12) on gastric nociceptive response induced by gastric acid stimulation and explore the underlying mechanisms associated with nuclei of the medullary viscerosensory and visceral motor neurons. MethodsTwenty SD rats were given intragastric administration of 0.5 mol/L diluted hydrochloric acid (0.5 ml/100 g) to induce gastric nociceptive response induction. Eight rats were randomly selected to record the gastric slow wave (GSW) area under the curve, and extracellular discharge frequency of neurons in the nucleus of the solitary tract (NTS) and dorsal motor nucleus of the vagus nerve (DMV) before intragastric administration and at 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes after intragastric administration. The remaining 12 rats received electroacupuncture intervention at Zhongwan within 5 to 25 minutes after intragastric administration of diluted hydrochloric acid, with a duration of one minute. The GSW area under the curve and extracellular discharge frequency of NTS and DMV neurons were compared between the 1-minute intervals before and after electroacupuncture intervention. ResultsCompared to the baseline before intragastric administration, the area under the curve of GSW significantly increased at 1, 5, 10, 15, 20, and 25 minutes after intragastric administration, and the extracellular discharge frequency of excitatory neurons in the NTS (accounting for 90%, 57/63) significantly increased at 1, 5, 10, 15, 20, 25, 30, 35, and 40 minutes, both reaching peak values at 1 minute after intragastric administration (P<0.01 or P<0.05). The extracellular discharge frequency of inhibitory neurons in the DMV (accounting for 91%, 20/22) showed a non-significant increase at 1 minute after intragastric administration (P>0.05), but significantly decreased at other timepoints (P<0.05). Compared to the baseline before electroacupuncture intervention, the GSW area under the curve and the extracellular discharge frequency of excitatory neurons in the NTS significantly decreased (P<0.05), while the extracellular discharge frequency of inhibitory neurons in the DMV showed no significant difference (P>0.05). ConclusionElectroacupuncture at Zhongwan can improve gastric nociceptive response induced by gastric acid stimulation, possibly by reducing the transmission of visceral sensation and decreasing the excitability of NTS neurons in the medulla.

RESUMO

Objective:To investigate the safety and feasibility of Ivor-Lewis procedure under uniportal video-assisted thoracoscopy(VATS) for esophageal cancer and Siewert type I esophago-gastric junction carcinoma.Methods:The patients with middle-lower segment esophageal cancer or Siewert type I esophago-gastric junction carcinoma received minimally invasive esophagectomy between October 2020 and June 2021, and the clinical data was collected and analyzed.Results:26 patients received Ivor-Lewis procedure underwent uniportal VATS, while 45 patients underwent McKeown surgery under multiport VATS. The average operation time of patients in the two groups were(265±110)min and (235±94)min, and the average intraoperative blood loss were(80±57)ml and(105±60)ml. The mean number of lymph nodes removed in the surgery were (19.3±2.9) and 18.6±2.7 respectively in two groups, and the mean length of hospital stay was(7.5±3.5)days and(8.3±2.7)days. The incidence of perioperative complications were not significantly different in two groups. The VAS score of patients received Ivor-Lewis procedure underwent uniportal VATS was lower than that of patients received McKeown surgery in ostoperative day 1, day 3, day 7 and 1 month. The difference was statistically significant in two groups( P<0.05). Conclusion:The Ivor-Lewis procedure under uniportal VATS for esophageal cancer and Siewert type I esophago-gastric junction carcinoma has the advantage of less postoperative pain, and the procedure is feasible in clinical practice.

RESUMO

Objective:To explore the changes of bone turnover markers and geometric parameters of hip bone in overweight postmenopausal women with metabolic syndrome(MS), as well as the influence of MS components. To analyze the association of these factors with the risk of fracture.Methods:A total of 505 overweight postmenopausal female patients who underwent health check-up in Lianhu Community Service Center, Danyang City, Jiangsu Province from January to December 2017 were selected. According to the MS diagnostic criteria of the International Diabetes Federation(2009), the patients were divided into MS group( n=331)and non-MS group( n=174). Blood samples were collected to determine the level of procollagen type 1 N-terminal propeptide(P1NP)and carboxy-terminal cross-linked telopeptide of type 1 collagen(CTX). Bone mineral density and hip bone geometry parameters were tested with dual-energy X-ray absorptiometry and hip structural analysis software. Results:The incidence of osteoporotic fracture and hip fracture in MS group was significantly higher than that in non-MS group(21.1% vs 13.8%, 4.8% vs 1. 1%, P<0.05). However, the bone mineral density of lumbar vertebra 1-4, femoral neck, and total hip in MS group was significantly higher than that in non-MS group, which remained after adjusting for age( P<0.05), but the difference disappeared after further adjustment for body mass index( P>0.05). The P1NP, CTX, femur strength index(FSI), section modulus(SM), and cross-sectional area(CSA)of MS group were significantly lower than those of non-MS group, the buckling ration(BR)was significantly higher than that in non-MS group, and the differences were still statistically significant after adjusting for age and body mass index( P<0.05). There was no significant difference in bone mineral density of lumbar vertebra 1-4, femoral neck, total hip, P1NP, and CTX between fracture group and non-fracture group in patients with MS. But FSI, SM, cross-sectional moment of inertia(CSMI), and CSA were significantly lower, BR was significantly higher( P<0.05) and femur strength decreased in patients with fracture. Regression analysis showed that high BR was an independent risk factor for fracture risk, while high FSI, SM, CSMI, and CSA were protective factors. Multivariate linear regression analysis showed that wasit circumference, diastolic blood pressure, and fasting plasma glucose were the main MS components affecting bone mineral density, bone turnover indexes, and hip bone geometry parameters. Conclusions:Overweight postmenopausal MS patients had decreased bone turnover rate, femoral strength, and relatively poor bone quality. Hip bone geometry parameters can be used as one of the methods to assess fracture risk in MS patients. Waist circumference, diastolic blood pressure, and fasting blood glucose are the important MS components affecting bone mass and bone quality.

RESUMO

Objective:To study the clinical characteristics and management strategies of late bleeding after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 58 patients with post-pancreaticoduodenectomy hemorrhage (PPH) admitted to the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University from March 2018 to March 2022 were retrospectively analyzed, including 42 males and 16 females, aged (61.88±11.02) years old. According to the occurrence of intra-abdominal erosion factors (e.g., pancreatic fistula, biliary fistula, gastrointestinal anastomotic fistula, intra-abdominal abscess), patients were divided into the erosion group ( n=42) and non-erosion group ( n=16). All patients underwent standard lymphadenectomy. Clinical data including the PPH time-point, occurrence of rebleeding, and treatment outcomes were accessed. The management strategies of PPH in the two groups of patients were analyzed. Results:The PPH time-point in the erosion group and non-erosion patients was 8.00 (5.00, 19.25) d and 21.50 (12.75, 26.75) d, respectively ( P=0.001). PPH can occurred within one month after surgery in both erosion and non-erosion groups. In the erosion group, 31 cases (73.81%, 31/42) were treated by re-operation, two (4.76%, 2/42) by interventional radiology and nine (21.43%, 9/42) with conservative protocol, respectively. In the non-erosion group, five cases (31.25%, 5/16) were treated by re-operation, seven (43.75%, 7/16) by interventional radiology and four (25.00%, 4/16) with conservative protocol, respectively. The incidence of re-bleeding is higher in the erosion group [47.6% (20/42) vs 12.5% (2/16), P<0.05]. Clinical manifestations, sites and severity of bleeding, and treatment outcomes were also different in the erosion and non-erosion groups (all P<0.05). Conclusions:The occurrence of intra-abdominal erosion factors can affect the clinical characteristics and treatment strategy of late bleeding after laparoscopic pancreaticoduodenectomy. Surgery remains the treatment of choice for post-pancreaticoduodenectomy hemorrhage either as an urgent or last resort.

RESUMO

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

RESUMO

Objective:To explore the clinical efficacy and safety of single-layer with full thickness of duct-to-mucosa pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of 45 patients who underwent laparoscopic pancreaticoduodenectomy with the procedures of single-layer with full thickness in Second Hospital of Hebei Medical University from Jan 2020 to Jan 2022 were retrospectively collected and compared with 45 matched patients with traditional two-layer pancreaticojejunostomy.Results:The laparoscopic pancreaticoduodenectomy procedures were successfully performed in all the 90 cases. The mean operation time (285.6±92.4 minutes) and the media pancreaticojejunostomy time 20(15, 35) minutes) of the single-layer with full thickness pancreaticojejunostomy group were shorter than those of the two-layer pancreaticojejunostomy group [the mean operation time: 317.0±85.5 minutes, the media pancreaticojejunostomy time: 46(30, 58) minutes] with significantly statistical differences (all P value<0.05). There were no significantly statistical differences on intraoperative blood loss, the postoperative complications or hospital stay between the two groups. Conclusions:Compared with traditional pancreaticojejunostomy, the single-layer with full thickness of duct-to-mucosa pancreaticojejunostomy is simple and safe, which has the advantage of easy manipulation and less time-consuming and can be recommended for laparoscopic procedures.

RESUMO

OBJECTIVE@#Xiaotan Sanjie recipe (XTSJ), a Chinese herbal compound medicine, exerts a significant inhibitory effect on gastric cancer (GC) metastasis. This work investigated the mechanism underlying the XTSJ-mediated inhibition of GC metastasis.@*METHODS@#The effect of XTSJ on GC metastasis and the associated mechanism were investigated in vitro, using GC cell lines, and in vivo, using a GC mouse model, by focusing on the expression of Glc-N-Ac-transferase V (GnT-V; encoded by MGAT5).@*RESULTS@#The migration and invasion ability of GC cells decreased significantly after XTSJ administration, which confirmed the efficacy of XTSJ in treating GC in vitro. XTSJ increased the accumulation of E-cadherin at junctions between GC cells, which was reversed by MGAT5 overexpression. XTSJ administration and MGAT5 knockdown alleviated the structural abnormality of the cell-cell junctions, while MGAT5 overexpression had the opposite effect. MGAT5 knockdown and XTSJ treatment also significantly increased the accumulation of proteins associated with the E-cadherin-mediated adherens junction complex. Furthermore, the expression of MGAT5 was significantly lower in the lungs of BGC-823-MGAT5 + XTSJ mice than in those of BGC-823-MGAT5 + solvent mice, indicating that the ability of gastric tumors to metastasize to the lung was decreased in vivo following XTSJ treatment.@*CONCLUSION@#XTSJ prevented GC metastasis by inhibiting the GnT-V-mediated E-cadherin glycosylation and promoting the E-cadherin accumulation at cell-cell junctions.

RESUMO

AIM:To investigate the effectiveness of surgical simulator-based small-incision extracapsular cataract extraction training for young ophthalmologists.METHODS:Prospective and controlled study. A total of 48 young participants who had completed at least 3a standardized residency training or had obtained the attending certificate in the He Eye Specialist Hospital from 2020 to 2022 were enrolled. All the participants were randomly divided into simulator surgical operation training group(experimental group, n=24)and real animal eye operation training group(control group, n=24)after passing the theoretical training and assessment of small incision extracapsular cataract extraction. The participants in the experimental group and control group were trained with the surgical simulator and pig eyes respectively. After training, the overall effectiveness of training in both groups was rated using the simulator and pig eye operation was evaluated.RESULTS: The participants in the experimental group used less time than the participants in the control group on simulator assessment(all P&#x003C;0.05). The scores of injecting viscoelastics during keratonyxis, nucleus delivery and hydrate the paracentesis site steps were not different on simulator assessment between the two groups(P&#x003E;0.05). For the rest of the steps, the scores of experimental group were higher than those of the control group(all P&#x003C;0.05). Participants in the experimental group had significantly higher scores than control group on pig eye operation assessment(all P&#x003C;0.05). In the experimental group, the scores of the scleral groove dissection, tunnel dissection, continuous circular capsulorhexis, hydrodissection and hydro-prolapse and nucleus delivery steps had no significant difference between the surgical simulator and pig eye operation(P=0.068, 0.126, 0.960, 0.520, 0.206). The scores of injecting viscoelastics during keratonyxis, tunnel puncture into anterior chamber and hydrate the paracentesis site steps were significantly lower on simulator assessment than pig eye operation(P=0.007, 0.014, &#x003C;0.01). The scores of the cortex removal and intraocular lens(IOL)implantation were significantly higher on simulator assessment than eye of real animal(P=0.035, &#x003C;0.01).CONCLUSION:The application of surgical simulator on training small incision extracapsular cataract extraction skills for young ophthalmologists could significantly improve their skills in cataract surgery operation, providing a new mode and idea for the establishment of standardized cataract surgery training for young ophthalmologists.

RESUMO

The study aims to investigate the anti-hepatic fibrosis and anti-inflammatory activities of palbinone, and to explore the internal regulatory mechanism, so as to lay an active foundation for its development as an anti-non-alcoholic steatohepatitis (NASH) candidate. First, sulforhodamine B (SRB) method was used to detect the effect of palbinone on the proliferation of human hepatic stellate cells LX-2 and rat hepatic stellate cells HSC-T6. Following, in the in vitro hepatic fibrosis cell model that activated by transforming growth factor beta 1 (TGF-β1), quantitative real-time PCR (qRT-PCR) and Western blot were used to detect the inhibitory effect of different concentrations of palbinone on the transcription level and protein expression level of hepatic fibrosis markers. And the regulating mechanism of palbinone on fibrosis-related genes was analyzed at the same time. In addition, in the inflammatory cell model that induced by lipopolysaccharide (LPS) and nigericin, ELISA was used to detect the effect of palbinone on the released interleukin-1β (IL-1β) level. At the same time, Western blot was used to detect the effect of palbinone on the related proteins of inflammatory pathway. The results showed that palbinone could significantly inhibit the proliferation activity of LX-2 and HSC-T6, and their half maximal inhibitory concentration (IC50) values ​​were (375.11 ± 55.45) and (260.27 ± 36.81) nmol·L-1, respectively. In addition, palbinone showed a dose-dependent inhibitory effect on the expression levels of TGF-β1-induced fibrosis-related genes, including collagen type Ⅰ α 1 (COL1A1), TGF-β1, α-smooth muscle actin (α-SMA) and tissue inhibitor of metalloproteinase 1 (TIMP1). Mechanism study showed that palbinone may decrease the expression level of Yes-associated protein (YAP), thereby weakening its activation effect on the downstream fibrosis pathway. In addition, palbinone also exerted an anti-inflammatory effect by inhibiting the activity of nuclear factor kappa-B (NF-κB) signaling pathway and reducing inflammatory factors cysteinyl aspartate specific proteinase-1 (caspase-1) and IL-1β release. In conclusion, palbinone can not only inhibit the proliferation and activation of hepatic stellate cells by inhibiting the expression of YAP, but also inhibit the expression and release of inflammatory factors at the same time. All these studies provide theoretical support for the development of palbinone as an anti-nonalcoholic steatohepatitis drug.

RESUMO

Objective To investigate the prevalence of Echinococcus infection in small mammals in Shiqu County, Sichuan Province from 2015 to 2020, so as to provide insights into echinococcosis control in Shiqu County. Methods One setting with frequent activity of small mammals was sampled as the survey site from each of 9 townships where human alveolar echinococcosis was hyperendemic, in Shiqu County, Sichuan Province from 2015 to 2020. Two quadrats measuring 50 m × 50 m were assigned in each survey site during the period between July and August from 2015 to 2020 to capture all small mammals in quadrats, and the species of small mammals were identified by morphological characteristics. All captured small mammals were dissected in the field and Echinococcus infection was identified by visual examinations. The affected organs of Echinococcus-infected small mammals were collected, and Echinococcus infection was detected using PCR assay, with Echinococcus species characterized. The prevalence of Echinococcus infection was calculated in small mammals, and the trends in the prevalence of Echinococcus infection were analyzed during the period from 2015 to 2020. In addition, the prevalence of Echinococcus infection was compared in small mammals using visual examinations and PCR assay. Results A total of 2 692 small mammals were captured in the survey sites of Shiqu County from 2015 to 2020, and morphology characterized 1 360 Microtus fuscus (50.52%) and 1 332 Plateau pika (49.48%). The prevalence rates of Echinococcus infection were 35.63%, 19.16%, 21.41%, 8.40%, 7.68% and 4.44% by visual examinations and 18.96%, 5.36%, 5.61%, 4.58%, 3.30% and 0.37% by PCR assay in small mammals in Shiqu County from 2015 to 2020, both showing a tendency towards a decline year by year (χ2 = 215.024 and 117.045, both P values < 0.001). The prevalence of Echinococcus infection was significantly higher in small mammals by visual examinations than by PCR assay during the period from 2015 to 2020 except in 2018 (χ2= 33.597, 21.815, 51.373, 17.268 and 9.537, all P values < 0.01). PCR assay detected a reduction in the prevalence of E. multilocularis infection from 10.21% to 0.37% and a reduction in the prevalence of E. shiquicus infection from 8.75% to 0 in small mammals in Shiqu County from 2015 to 2020, both appearing a tendency towards a decline year by year (χ2 = 117.045 and 43.436, both P values < 0.001). In addition, the prevalence of E. multilocularis and E. shiquicus infections reduced from 15.19% to 0.45% and from 8.23% to 0 in M. fuscus, and the prevalence of E. multilocularis and E. shiquicus infections reduced from 7.76% to 0 and from 9.01% to 0 in P. pika in Shiqu County from 2015 to 2020. Conclusions M. fuscus and P. pika were dominant species of small mammals in Shiqu County, Sichuan Province from 2015 to 2020, and E. multilocularis infection was mainly found in M. fuscus and E. shiquicus infection mainly found in P. pika. The prevalence of Echinococcus infection appeared a tendency towards a decline in both M. fuscus and P. pika year by year during the period from 2015 to 2020.

RESUMO

Pulmonary hypertension (PH) is an insidious pulmonary vasculopathy with high mortality and morbidity and its underlying pathogenesis is still poorly delineated. The hyperproliferation and apoptosis resistance of pulmonary artery smooth muscle cells (PASMCs) contributes to pulmonary vascular remodeling in pulmonary hypertension, which is closely linked to the downregulation of fork-head box transcriptional factor O1 (FoxO1) and apoptotic protein caspase 3 (Cas-3). Here, PA-targeted co-delivery of a FoxO1 stimulus (paclitaxel, PTX) and Cas-3 was exploited to alleviate monocrotaline-induced pulmonary hypertension. The co-delivery system is prepared by loading the active protein on paclitaxel-crystal nanoparticles, followed by a glucuronic acid coating to target the glucose transporter-1 on the PASMCs. The co-loaded system (170 nm) circulates in the blood over time, accumulates in the lung, effectively targets the PAs, and profoundly regresses the remodeling of pulmonary arteries and improves hemodynamics, leading to a decrease in pulmonary arterial pressure and Fulton's index. Our mechanistic studies suggest that the targeted co-delivery system alleviates experimental pulmonary hypertension primarily via the regression of PASMC proliferation by inhibiting cell cycle progression and promoting apoptosis. Taken together, this targeted co-delivery approach offers a promising avenue to target PAs and cure the intractable vasculopathy in pulmonary hypertension.

RESUMO

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

BACKGROUND@#Treatment duration of wrist-ankle acupuncture (WAA) is uncertain for post-thyroidectomy pain relief.@*OBJECTIVE@#This study evaluated the effect of different WAA treatment duration on post-operative pain relief and other discomforts associated with thyroidectomy.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This randomized controlled trial was conducted at a single research site in Guangzhou, China. A total of 132 patients receiving thyroidectomy were randomly divided into the control group (sham WAA, 30 min) and three intervention groups (group 1: WAA, 30 min; group 2: WAA, 45 min; group 3: WAA, 60 min), with group allocation ratio of 1:1:1:1. Acupuncture was administered within 1 hour of leaving the operating room.@*OUTCOMES AND MEASURES@#Primary outcome was patients' pain at the surgical site assessed by visual analogue scale (VAS) at the moment after acupuncture treatment (post-intervention). Secondary outcomes included the patients' pain VAS scores at 6, 12, 24, 48 and 72 h after the thyroidectomy, the 40-item Quality of Recovery (QoR-40) score, the grade of post-operative nausea and vomiting (PONV), and the use of additional analgesic therapy.@*RESULTS@#The adjusted mean difference (AMD) in VAS scores from baseline to post-intervention in group 1 was -0.89 (95% confidence interval [CI], -1.02 to -0.76). The decrease in VAS score at post-intervention was statistically significant in group 1 compared to the control group (AMD, -0.43; 95% CI, -0.58 to -0.28; P < 0.001), and in groups 2 and 3 compared to group 1 (group 2 vs group 1: AMD, -0.65; 95% CI, -0.81 to -0.48; P < 0.001; group 3 vs group 1: AMD, -0.66; 95% CI, -0.86 to -0.47; P < 0.001). The VAS scores in the four groups converged beyond 24 h after the operation. Fewer patients in group 2 and group 3 experienced PONV in the first 24 h after operation. No statistical differences were measured in QoR-40 score and the number of patients with additional analgesic therapy.@*CONCLUSION@#Compared with the 30 min intervention, WAA treatment with longer needle retention time (45 or 60 min) had an advantage in pain relief within 6 h after surgery. WAA's analgesic effect lasted for 6-12 h post-operatively. Please cite this article as: Han XR, Yue W, Chen HC, He W, Luo JH, Chen SX, Liu N, Yang M.

RESUMO

OBJECTIVE@#To analyze the femoral head collapse and the operation of osteonecrosis of the femoral head (ONFH) in different Japanese Investigation Commitee (JIC) types, in order to summarize the prognostic rules of each type of ONFH, and explore the clinical significance of CT lateral subtypes based on reconstruction of necrotic area of C1 type and verify their clinical effect.@*METHODS@#A total of 119 patients (155 hips) with ONFH between May 2004 and December 2016 were enrolled in the study. The total hips consisted of 34 hips in type A, 33 in type B, 57 in type C1, and 31 in type C2, respectively. There was no significant difference in age, gender, affected side, or type of ONFH of the patients with differenct JIC types ( P>0.05). The 1-, 2-, and 5-year femoral head collapse and operation of different JIC types were analyzed, as well as the survival rate (with femoral head collapse as the end point) of hip joint between different JIC types, hormonal/non-hormonal ONFH, asymptomatic and symptomatic (pain duration >6 months or ≤6 months), and combined preserved angle (CPA) ≥118.725° and CPA<118.725°. JIC types with significant differences in subgroup surgery and collapse and with research value were selected. According to the location of the necrotic area on the surface of the femoral head, the JIC classification was divided into 5 subtypes in the lateral CT reconstruction, and the contour line of the necrotic area was extracted and matched to the standard femoral head model, and the necrosis of the five subtypes was presented by thermography. The 1-, 2-, and 5-year outcomes of femoral head collapse and operation in different lateral subtypes were analyzed, and the survival rates (with collapse of the femoral head as the end point) between CPA≥118.725° and CPA<118.725° hip in patients with this subtype were compared, as well as the survival rates of different lateral subtypes (with collapse and surgery as the end points, respectively).@*RESULTS@#The femoral head collapse rate and operation rate in the 1-, 2-, and 5-year were significantly higher in patients with JIC C2 type than in patients with other hip types ( P<0.05), while in patients with JIC C1 type than in patients with JIC types A and B ( P<0.05). The survival rate of patients with different JIC types was significantly different ( P<0.05), and the survival rate of patients with JIC types A, B, C1, and C2 decreased gradually. The survival rate of asymptomatic hip was significantly higher than that of symptomatic hip, and the survival rate of CPA≥118.725° was significantly higher than that of CPA<118.725° ( P<0.05). The lateral CT reconstruction of type C1 hip necrosis area was selected for further classification, including type 1 in 12 hips, type 2 in 20 hips, type 3 in 9 hips, type 4 in 9 hips, and type 5 in 7 hips. There were significant differences in the femoral head collapse rate and the operation rate among the subtypes after 5 years of follow-up ( P<0.05). The collapse rate and operation rate of types 4 and 5 were 0; the collapse rate and operation rate of type 3 were the highest; the collapse rate of type 2 was high, but the operation rate was lower than that of type 3; the collapse rate of type 1 was high, but the operation rate was 0. In JIC type C1 patients, the survival rate of the hip joint with CPA≥118.725° was significantly higher than that with CPA<118.725° ( P<0.05). In the follow-up with femoral head collapse as the end point, the survival rates of types 4 and 5 were all 100%, while the survival rates of types 1, 2, and 3 were all 0, and the difference was significant ( P<0.05). The survival rate of types 1, 4, and 5 was 100%, of type 3 was 0, and of type 2 was 60%, showing significant difference ( P<0.05).@*CONCLUSION@#JIC types A and B can be treated by non-surgical treatment, while type C2 can be treated by surgical treatment with hip preservation. Type C1 was classified into 5 subtypes by CT lateral classification, type 3 has the highest risk of femoral head collapse, types 4 and 5 have low risk of femoral head collapse and operation, type 1 has high femoral head collapse rate but low risk of operation; type 2 has high collapse rate, but the operation rate is close to the average of JIC type C1, which still needs to be further studied.

RESUMO

Objectives To learn the echocardiography skills of intensivists after receiving a basic critical care echocardiography training course, and investigate factors that may influence their performance. Methods We completed a web-based questionnaire that assessed the skills in ultrasound scanning techniques of intensivists who took a training course on basic critical care echocardiography held in 2019 and 2020. Mann-Whitney test was used to analyze the factors which might affect their performance on image acquisition, recognizing clinical syndrome, and measuring the diameter of inferior vena cava, left ventricular ejection fraction and left ventricular outflow tract velocity-time integral.Results We enrolled 554 physicians from 412 intensive care units across China. Among them, 185 (33.4%) reported that they had 10%-30% chance of being misled by critical care echocardiography when making therapeutic decision, and 34 (6.1%) reported that the chance was greater than 30%. Intensivists who performed echocardiography under the guidance of a mentor and finished ultrasound scanning more than 10 times per week reported significant higher scores in image acquisition, clinical syndrome recognition, and quantitative measurement of inferior vena cava diameter, left ventricular ejection fraction and left ventricular outflow tract velocity-time integral than those without mentor and performing echocardiography 10 times or less per week respectively (all P < 0.05).Conclusion The skills in diagnostic medical echocardiography of Chinese intensivists after a basic echocardiographic training course remain low, and further quality assurance training program is clearly warranted.

RESUMO

The latest guideline about ulcerative colitis (UC) clinical practice stresses that mucosal healing, rather than anti-inflammation, is the main target in UC clinical management. Current mucosal dysfunction mainly closely relates to the endoscopic intestinal wall (mechanical barrier) injury with the imbalance between intestinal epithelial cells (IECs) regeneration and death, as well as tight junction (TJ) dysfunction. It is suggested that biological barrier (gut microbiota), chemical barrier (mucus protein layer, MUC) and immune barrier (immune cells) all take part in the imbalance, leading to mechanical barrier injury. Lots of experimental studies reported that acupuncture and moxibustion on UC recovery by adjusting the gut microbiota, MUC and immune cells on multiple targets and pathways, which contributes to the balance of IEC regeneration and death, as well as TJ structure recovery in animals. Moreover, the validity and superiority of acupuncture and moxibustion were also demonstrated in clinic. This study aims to review the achievements of acupuncture and moxibustion on mucosal healing and analyse the underlying mechanisms.

RESUMO

Objective: To determine whether the adenine base editor (ABE7.10) can be used to fix harmful mutations in the human G6PC3 gene. Methods: To investigate the safety of base-edited embryos, off-target analysis by deep sequencing was used to examine the feasibility and editing efficiency of various sgRNA expression vectors. The human HEK293T mutation models and human embryos were also used to test the feasibility and editing efficiency of correction. Results: ①The G6PC3(C295T) mutant cell model was successfully created. ②In the G6PC3(C295T) mutant cell model, three distinct Re-sgRNAs were created and corrected, with base correction efficiency ranging from 8.79% to 19.56% . ③ ABE7.10 could successfully fix mutant bases in the human pathogenic embryo test; however, base editing events had also happened in other locations. ④ With the exception of one noncoding site, which had a high safety rate, deep sequencing analysis revealed that the detection of 32 probable off-target sites was <0.5% . Conclusion: This study proposes a new base correction strategy based on human pathogenic embryos; however, it also produces a certain nontarget site editing, which needs to be further analyzed on the PAM site or editor window.

RESUMO

AIM: To investigate the influencing factors of punctate staining of corneal epithelium in patients wearing orthokeratology.METHOD: Data of 280 cases wearing orthokeratology were collected, including 185 cases in the group without corneal staining and 95 cases in the group with corneal staining. All patients were examined for general distant vision, intraocular pressure, slit lamp, fundus examination after mydriasis, comprehensive optometry, corneal topography, corneal thickness, corneal endothelium, axial length, Schirmer Ⅰtest(SⅠt)before wearing lenses, meibomian gland loss score before wearing lenses, eccentric distance, interleukin-2(IL-2)in tear, tumor necrosis factor-α(TNF-α)content analysis and so on. The influencing factors of corneal epithelium punctate staining were analyzed by univariate and multivariate Logistic regression.RESULTS: There were significant differences in preoperative diopter, preoperative meibomian gland deletion score, IL-2, TNF-α and lens sediment between the two groups(all P&#x003C;0.05). Logistic regression analysis showed that diopter before wearing lenses was a protective factor for corneal epithelium punctate staining. Before wearing lenses, the loss of meibomian gland score, IL-2, TNF-α and lens deposits were the risk factors of corneal epithelium punctate staining. In the detection of corneal epithelium punctate staining, the comprehensive advantage of lens deposits was obvious, the specificity of lens deposits was higher, and the sensitivity of IL-2 was the highest. CONCLUSIONS: Before wearing lenses, diopter is the protective factor of corneal epithelium punctate staining, and the loss of meibomian gland score, IL-2, TNF-α and lens deposits are the risk factors of corneal epithelium punctate staining.
