Work and lifestyle influencing factors for thyroid cancer among young and middle-aged patients with thyroid nodules / 环境与职业医学

Background The number of persons with thyroid nodules has increased rapidly in recent years, and thyroid cancer caused by malignant nodules has become a key problem endangering the health of young and middle-aged groups in China. Objective To explore work and lifestyle influencing factors for developing thyroid cancer among young and middle-aged patients with thyroid nodules. Methods The subjects with thyroid nodules were reported by routine physical examines ordered at the Huadong Sanatorium. We conducted a 1∶4 matched case-control study in which 232 patients diagnosed with thyroid cancer from 2012 to 2022 were matched to 928 controls by gender and age (±5 years). A validated questionnaire was used to collect data on work and lifestyle behaviors. Univariate and multivariate logistic regression models were applied to explore potential relationships between selected factors (including environment, working hours, stress, diet, exercise, and mental health) and thyroid cancer. Spearman rank correlation was used to analyze the correlations between variables. Results The results of univariate logistic regression showed a history of thyroid cancer reported among first-degree relatives (OR=6.059, 95%CI: 1.007, 36.473), obesity (OR=1.973, 95%CI: 1.296, 3.004), noise and vibration exposure (OR=1.988, 95%CI: 1.143, 3.456), frequent stress (OR=2.093, 95%CI: 1.231, 3.559), frequent depression (OR=2.034, 95%CI: 1.048, 3.947), frequent anger (OR=1.791, 95%CI: 1.066, 3.012), frequent fried food diet (OR=1.535, 95%CI: 1.026, 2.297), and frequent fast food diet (OR=1.836, 95%CI: 1.048, 3.215) were risk factors for reporting thyroid cancer developing from thyroid nodules, while regular meals (OR=0.245, 95%CI: 0.061, 0.989) and frequent exercise (OR=0.571, 95%CI: 0.342, 0.952) were protective factors for reporting no thyroid cancer. The results of Spearman correlation analysis showed that body mass index was positively correlated with frequent fried food, fast food, and sugary beverage diets (r=0.123, 0.083, 0.077, P<0.01), and negatively correlated with frequent depression and anger (r=−0.090, −0.070, P<0.05). The results of multiple logistic regression found that a history of thyroid cancer reported among first-degree relatives (OR=6.712, 95%CI: 1.071, 42.066), obesity (OR=2.032, 95%CI: 1.321, 3.125), noise and vibration exposure (OR=1.991, 95%CI: 1.089, 3.637), and frequent stress (OR=2.468, 95%CI: 1.417, 4.300) were associated with an elevated risk of reporting thyroid cancer developing from thyroid nodules patients. Regular exercise (frequency≥3 times·week−1, > 30 min per episode) (OR=0.516, 95%CI: 0.300, 0.890) was associated with a lowered risk of reporting thyroid cancer. Conclusions Multiple risk factors associated with reporting thyroid cancer among young and middle-aged groups with thyroid nodules are identified, such as obesity, noise and vibration exposure, frequent stress, and lack of exercise.

Paired t test was conducted in the two groups, P < 0.01 with significant statistical difference; The mean maximum position deviation between T1 group and T2 group of the midline mandibular region in labial lingual direction was (0.32±0.14) mm, that was (0.40±0.23) mm in vertical direction; the mean maximum position deviation of molar area in buccal lingual direction was (0.35±0.23) mm and that was (0.33±0.20) mm in vertical direction. In the vertical and horizontal directions, the maximum position deviation of mandibles between group T1 and group T2 was controlled within 0.5 mm. In the process of clinical complete dentures try-in, there was no deviation from the center line of dentures. There was not warping, swinging and other poor stability phenomena in T1 and T2 groups.@*CONCLUSION@#The digital manufacturing of simple intraoral Gothic arch-tracing device can be used to determine the centric relation of complete dentures, which can not only save time of clinical operation, but also ensure the accuracy of the centric relation.

Protective effect and mechanism of AKAP1 on myocardial injury induced by highland hypobaric hypoxia / 中华劳动卫生职业病杂志

Objective: To investigate the protective effect and its possible mechanism of A-kinase anchored protein 1 (AKAP1) on the myocardial injury induced by highland hypobaric hypoxia. Methods: From January 2021 to May 2022, male C57BL/6 SPF grade mice were divided into wild type control (WT) group and highland hypobaric hypoxia (HH) group with 6 mice in each group. HH group simulated 6000 m altitude with low pressure oxygen chamber for 4 weeks to build the model. Primary myocardial cells of SD rats were divided into normoxia control group and hypoxia experimental group (n=3). Cell models were constructed in a three-gas hypoxia incubator with 1% oxygen concentration for 24 h. AKAP1 protein and mRNA expression in myocardial tissue and cells were detected by western blotting, immunohistochemistry and quantitative real-time polymerase chain reaction (qPCR). After myocardial point injection of the AKAP1 or the control adenovirus, the mice were divided into 3 groups (n=6) : WT group, highland hypobaric hypoxia overexpression control group (HH+Ad-Ctrl group) and highland hypobaric hypoxia overexpression experimental group (HH+Ad-AKAP1 group). The cardiac function of mice was detected by noninvasive M-type ultrasonic cardiomotive, myocardial fibrosis was detected by Masson and Sirius Red staining, and cardiomyocyte hypertrophy was detected by wheat germ agglutinin. After the expression of AKAP1 in primary cardiomyocytes was downregulated by siRNA and upregulated by adenovirus, the cells were divided into three groups (n=3) : normoxia control group, hypoxia interference control group (hypoxia+siCtrl group), hypoxia AKAP1 knockdown group (hypoxia+siAKAP1 group) ; normoxia control group, hypoxia overexpression control group (hypoxia+Ad-Ctrl group), hypoxia AKAP1 overexpression group (hypoxia+Ad-AKAP1 group). Apoptosis was detected by flow cytometry, AKAP1, apoptosis-related protein and mRNA expression levels were detected by western blotting and qPCR, mitochondrial membrane potential was detected by JC-1 staining, and mitochondrial reactive oxygen specie (ROS) level was detected by MitoSOX. Results: The expression of AKAP1 in cardiac muscle of HH group was lower than that in the WT group, and the expression of AKAP1 in hypoxia experimental group was lower than that in normoxia control group (P<0.01). Compared with WT group, the left ventricular ejection fraction and fraction shortening of left ventricle in HH+Ad-Ctrl group were decreased (P<0.01), myocardial fibrosis and hypertrophy were aggravated (P<0.01), and the expression of B-cell lymphoma-2 (BCL-2) was decreased, the expressions of BCL-2-associated X protein (BAX), Caspase 3 and Caspase 9 were increased (P<0.01). After AKAP1 overexpression, compared with HH+Ad-Ctrl group, the left ventricular ejection fraction and left ventricular fraction shortening were increased in HH+Ad-AKAP1 group (P<0.01), myocardial fibrosis and hypertrophy were reduced (P<0.01), and the expression of BCL-2 was increased, the expressions of BAX, Caspase 3 and Caspase 9 were decreased (P<0.01). Compared with normoxia control group, the expression of BCL-2 in hypoxia+siCtrl group was decreased, the expressions of BAX, Caspase 3, Caspase 9 were increased, the apoptosis level was increased (P<0.01), the mitochondrial membrane potential was decreased and the production of ROS was increased (P<0.01). After AKAP1 knockdown, compared with hypoxia+siCtrl group, the expression of BCL-2 in hypoxia+siAKAP1 group was decreased, the expressions of BAX, Caspase 3, Caspase 9 were increased, the apoptosis level was increased (P<0.01), mitochondrial membrane potential was decreased, and the production of ROS was increased (P<0.01). After AKAP1 overexpression, compared with hypoxia+Ad-Ctrl group, the expression of BCL-2 in hypoxia+Ad-AKAP1 group was increased, the expressions of BAX, Caspase 3 and Caspase 9 were decreased (P<0.05), the apoptosis level was decreased (P<0.01), and the mitochondrial membrane potential was enhanced, and the production of ROS was decreased (P<0.01) . Conclusion: The downregulation of AKAP1 in cardiomyocytes under highland hypobaric hypoxia may lead to the decrease of mitochondrial membrane potential and the increase of ROS generation, leading to the apoptosis of cardiomyocytes, and thus aggravating the myocardial injury at highland hypobaric hypoxia.

Effect of intensive blood pressure control after successful endovascular therapy on outcomes in patients with anterior circulation stroke: a multicentre, open-label, blinded-endpoint, randomized controlled trial / 国际脑血管病杂志

Objective:To compare the effects of intensive and standard blood pressure control on the outcomes of patients with acute ischemic stroke in the anterior circulation who have successfully recanalized after endovascular therapy (EVT).Methods:A multicenter, open-label, blinded-endpoint, randomized controlled design was used. Patients with anterior circulation stroke received EVT and successfully recanalized in Nanjing First Hospital, Nanjing Medical University and several branch hospitals from July 2020 to October 2022 were prospectively included. They were randomly divided into the intensive blood pressure control group (target systolic blood pressure [SBP] 100-120 mmHg) or the standard blood pressure control group (target SBP 121-140 mmHg). The blood pressure of both groups needs to achieve the target within 1 h and maintain for 72 h. The primary outcome endpoint was outcome at 90 d, and the good outcome was defined as a score of 0-2 on the modified Rankin Scale. Secondary outcome endpoints included early neurological improvement, symptomatic intracranial hemorrhage (sICH) within 24 h, and death and serious adverse events within 90 d.Results:A total of 120 patients were included, including 63 in the intensive blood pressure control group and 57 in the standard blood pressure control group. There was no statistically significant difference in baseline characteristics between the two groups. The SBP at 72 h after procedure was 122.7±8.1 mmHg in the intensive blood pressure control group and 130.2±7.4 mmHg in the standard blood pressure control group, respectively. There were no significantly differences in the good outcome rate (54.0% vs. 54.4%; χ2=0.002, P=0.963), the early neurological improvement rate (45.2% vs. 34.5%; χ2=1.367, P=0.242), the incidence of sICH (6.3% vs. 3.5%; P=0.682), mortality (7.9% vs. 14.0%; χ2=1.152, P=0.283) and the incidence of serious adverse events (12.7% vs. 15.8%; χ2=0.235, P=0.628) at 90 d between the intensive blood pressure control group and the standard blood pressure control group. Conclusion:In patients with anterior circulation stroke and successful revascularization of EVT, early intensive blood pressure control don’t improve clinical outcomes and reduce the incidence of sICH.

Analysis of independent risk factors and establishment and validation of a prediction model for in-hospital mortality of multiple trauma patients / 中华创伤杂志

Objective:To explore the independent risk factor for in-hospital mortality of patients with multiple trauma, and to construct a prediction model of risk of death and validate its efficacy.Methods:A retrospective cohort study was performed to analyze the clinical data of 1 028 patients with multiple trauma admitted to Affiliated Hospital of Jiangsu University from January 2011 to December 2021. There were 765 males and 263 females, aged 18-91 years[(53.8±12.4)years]. The injury severity score (ISS) was 16-57 points [(26.3±7.6)points]. There were 153 deaths and 875 survivals. A total of 777 patients were enrolled as the training set from January 2011 to December 2018 for building the prediction model, while another 251 patients were enrolled as validation set from January 2019 to December 2021. According to the outcomes, the training set was divided into the non-survival group (115 patients) and survival group (662 patients). The two groups were compared in terms of the gender, age, underlying disease, injury mechanism, head and neck injury, maxillofacial injury, chest injury, abdominal injury, extremity and pelvis injury, body surface injury, damage control surgery, pre-hospital time, number of injury sites, Glasgow coma score (GCS), ISS, shock index, and laboratory test results within 6 hours on admission, including blood lactate acid, white blood cell counts, neutrophil to lymphocyte ratio (NLR), platelet counts, hemoglobin, activated partial thromboplastin time (APTT), fibrinogen, D-dimer and blood glucose. Univariate analysis and multivariate Logistic regression analysis were performed to determine the independent risk factors for in-hospital mortality in patients with multiple trauma. The R software was used to establish a nomogram prediction model based on the above risk factors. Area under the receiver operating characteristic (ROC) curve (AUC), calibration curve and clinical decision curve analysis (DCA) were plotted in the training set and the validation set, and Hosmer-Lemeshow goodness-of-fit test was performed.Results:Univariate analysis showed that abdominal injury, extremity and pelvis injury, damage control surgery, GCS, ISS, shock index, blood lactic acid, white blood cell counts, NLR, platelet counts, hemoglobin, APTT, fibrinogen, D-dimer and blood glucose were correlated with in-hospital mortality in patients with multiple trauma ( P<0.05 or 0.01). Logistic regression analysis showed that GCS≤8 points ( OR=1.99, 95% CI 1.12,3.53), ISS>25 points ( OR=7.39, 95% CI 3.50, 15.61), shock index>1.0 ( OR=3.43, 95% CI 1.94,6.08), blood lactic acid>2 mmol/L ( OR=9.84, 95% CI 4.97, 19.51), fibrinogen≤1.5 g/L ( OR=2.57, 95% CI 1.39,4.74) and blood glucose>10 mmol/L ( OR=3.49, 95% CI 2.03, 5.99) were significantly correlated with their in-hospital mortality ( P<0.05 or 0.01). The ROC of the nomogram prediction model indicated that AUC of the training set was 0.91 (95% CI 0.87, 0.93) and AUC of the validation set was 0.90 (95% CI 0.84, 0.95). The calibration curve showed that the predicted probability was consistent with the actual situation in both the training set and validation set. DCA showed that the nomogram prediction model presented excellent performance in predicting in-hospital mortality. In Hosmer-Lemeshow goodness-of-fit test, χ2 value of the training set was 9.69 ( P>0.05), with validation set of 9.16 ( P>0.05). Conclusions:GCS≤8 points, ISS>25 points, shock index>1.0, blood lactic acid>2 mmol/L, fibrinogen≤1.5 g/L and blood glucose>10 mmol/L are independent risk factors for in-hospital mortality in patients with multiple trauma. The nomogram prediction model based on these 6 predictive variables shows a good predictive performance, which can help clinicians comprehensively assess the patient′s condition and identify the high-risk population.

Objective:To explore the effect of endometriosis (EM) on reproductive outcomes of young patient with EM after laparoscopic treatment in the first in vitro fertilization-embryo transfer (IVF-ET) cycle.Methods:The clinical data and reproductive outcomes of 394 infertile patients with EM after laparoscopic treatment (EM group) and 3 242 infertile patients caused by gamete transport disorder (control group) in the first IVF-ET cycle were collected in Chongqing Health Center for Women and Children from January 2016 to June 2021. The information included baseline characteristics, oocyte retrieval, embryo development, clinical pregnancy, miscarriage, and live birth. Propensity score matching (PSM) method was used to perform 1∶2 matching between EM group and control group. The impact of EM on reproductive outcomes was analyzed in the retrospective observational study.Results:In the initial data, compared with control group, the number of two pronucleus (2PN) zygotes (9.7±4.8 vs 9.0±4.4), the number of transferable embryos (6.2±3.6 vs 5.5±3.4) and the rate of transferable embryos (64.0% vs 60.8%) on the third day were significantly lower in EM group, and the differences were statistically significant (all P<0.05). After PSM was performed, there were 394 and 787 cases in EM group and control group, respectively. Compared with control group, the number of 2PN zygotes (9.7±4.9 vs 9.0±4.4), the 2PN fertility rate (77.1% vs 75.3%), the number of transferable embryos on the third day (6.2±3.6 vs 5.5±3.4), the transferable embryos rate on the third day (63.8% vs 60.8%) were significantly lower in EM group, and the differences were statically significant (all P<0.05). The study did not find the effect of EM on embryo implantation rate, pregnancy rate, early miscarriage rate, live birth rate and preterm birth rate (all P>0.05). Conclusions:EM might interfere with the development of oocytes and embryos. Obtaining top-quality embryos may be an effective way to improve the prognosis of patients with EM after laparoscopic treatment.

Systematic review and Meta-analysis of efficacy and safety of Shufeng Jiedu Capsules in treatment of influenza / 中国中药杂志

This study aims to systematically review the efficacy and safety of Shufeng Jiedu Capsules in the treatment of influenza. The randomized controlled trial(RCT) of Shufeng Jiedu Capsules alone or in combination with conventional western medicine for treating influenza were retrieved from PubMed, EMbase, Cochrane Library, Web of Science, SinoMed, CNKI, VIP, Wanfang, and ClinicalTrails.gov. The data analysis was performed in RevMan 5.4.1. The Cochrane risk of bias assessment tool was used to evaluate the quality of the involved RCT, and GRADEpro GDT to assess the quality of the evidence. A total of 11 RCTs involving 1 836 patients were included in this study. Compared with conventional western medicine, Shufeng Jiedu Capsules/Shufeng Jiedu Capsules + conventional western medicine improved the response rate(RR=1.09, 95%CI[1.03, 1.15], P=0.002), shortened the time to relief of cough, and increased the 3-day sore throat relief rate, whereas there was no significant difference in the time to fever abatement, the time to relief of sore throat, 3-day cough relief rate, or 3-day runny nose relief rate. Subgroup-analysis showed that Shufeng Jiedu Capsules + conventional western medicine improved the response rate(RR=1.11, 95%CI[1.08, 1.15], P<0.000 01), shortened the time to relief of cough, and increased the 3-day relief rate of symptoms(cough, sore throat, and runny nose) compared with conventional western medicine alone, while there was no significant difference in the time to fever abatement or the time to relief of sore throat. Shufeng Jiedu Capsules alone could not improve the response rate(RR=0.97, 95%CI[0.93, 1.02], P=0.19). In addition, Shufeng Jiedu Capsules/Shufeng Jiedu Capsules + conventional western medicine vs conventional western medicine were no significant difference in adverse reactions(RR=0.98, 95%CI[0.57, 1.69], P=0.95). The available evidence suggests that Shufeng Jiedu Capsules is effective and safe in the treatment of influenza, and the combination of Shufeng Jiedu Capsules with conventional western medicine can accelerate the relief of symptoms. However, since the number and quality of the included studies were low, the above findings remained to be further verified by multicenter RCT with large sample sizes.

The two groups had similar mini-mental state examination (MMSE) scores and VAS scores at T 0 ( P>0.05). MMSE scores of the two groups were lower at T 1-T 3 than T 0. Group B had higher scores than group A at T 1-T 3: (23.14 ± 1.85) scores vs. (20.36 ± 2.15) scores, (25.18 ± 2.47) scores vs. (22.31 ± 2.35) scores, (27.05 ± 1.18) scores vs. (26.31 ± 1.01) scores, P<0.05. VAS scores of the two groups were higher at T 1-T 3 than T 0. Group B had lower scores than group A: (5.17 ± 0.54) scores vs. (6.21 ± 0.75) scores, (4.42 ± 0.51) scores vs. (5.63 ± 0.62) scores, (2.58 ± 0.34) scores vs. (3.14 ± 0.42) scores, P<0.05. The total incidence rates of adverse reactions in the two groups had no statistical difference ( χ2 = 0.17, P>0.05). Conclusions:Compared with intravenous-inhalation combined anesthesia, general anesthesia combined with epidural anesthesia has better anesthesia quality in patients undergoing laparoscopic hysterectomy, which can improve postoperative cognitive function and relieve pain. The two anesthesia methods are both safe.

Retrospective analysis of the effect of oral nutritional supplements during labor on delivery outcomes in low-risk pregnant women / 中华临床营养杂志

Objective:To explore the effect of oral nutritional supplements (ONS) during labor on delivery outcomes in low-risk pregnant women and the risk factors of cesarean section.Methods:A retrospective analysis was conducted in a total of 206 full-term pregnant women with singleton and cephalic presentation at the delivery center in our hospital from March 15th to May 15th, 2022. Standard diet education was given to all those women by midwives. Pregnant women who received the enteral nutrient solution prepared by the Department of Clinical Nutrition during labor were in the ONS group ( n = 110), while those who did not were in the control group ( n = 96). The baseline characteristics and delivery outcomes were compared between the two groups, and the risk factors of cesarean section were also analyzed. Results:There were no significant differences in terms of maternal age, height, baseline weight, baseline body mass index (BMI), weight gain during pregnancy, prenatal BMI, gestational week, intraspinal labor analgesia, oxytocin, gastrointestinal intolerance, neonatal length, and weight between the two groups ( P > 0.05). However, the total oral energy intake during labor in the ONS group was significantly higher than that in the control group ([1 349.99± 569.51] kJ vs [249.59 ± 455.19] kJ, P < 0.01). The rate of vaginal delivery in the ONS group was significantly higher than that in the control group (93.6% vs 81.3%, P = 0.01), and the duration of the first stage of labor ([487.06 ± 232.94] min vs [416.17 ± 191.13] min, P = 0.03) was also significantly longer in the ONS group. There were no significant differences between the two groups in terms of the duration of the second and third stages of labor, perineal laceration, cervical laceration, vaginal laceration, amount of bleeding, hospital stay, and Apgar score after birth ( P > 0.05). Multivariate logistic regression analysis showed that maternal age was a risk factor for changing to cesarean section in women with low-risk pregnancies ( OR 1.20, 95% CI 1.03 to 1.40, P = 0.02), while ONS during labor ( OR 0.31, 95% CI 0.11 to 0.85, P = 0.02) and intraspinal labor analgesia ( OR 0.10, 95% CI 0.04 to 0.26, P < 0.01) were protective factors. Conclusions:ONS during labor can significantly increase the vaginal delivery rate, without increasing the incidence of gastrointestinal intolerance in low-risk pregnant women. Maternal age is a risk factor for cesarean section while ONS during labor and intraspinal labor analgesia are protective factors in women with low-risk pregnancies.

Effect of calorie-restricted diet combined with intestinal microecological preparation on clinical outcomes in overweight/obese infertile patients / 中华临床营养杂志

Objective:To investigate the effects of calorie-restricted diet (CRD) combined with intestinal microecological preparation on the clinical outcomes in overweight/obese infertile patients undergoing frozen-thawed embryo transfer (FET) cycle.Methods:252 overweight/obese infertile patients who met the inclusion and exclusion criteria were included and divided into overweight intervention group, overweight control group, obese intervention group and obese control group, according to body mass index (BMI) and whether or not they received nutritional intervention. Clinical outcome indexes and changes in anthropometry and body composition before and after intervention were compared across all groups.Results:Body mass, BMI, body fat percentage, waist-to-hip ratio and visceral fat grade were significantly decreased after nutritional intervention in both overweight and obese intervention groups (both P<0.001). Among overweight patients, follicle count [(17.89±4.97) vs. (16.22±5.41), P=0.027], live births [(0.64±4.77) vs. (0.36±8.61), P=0.005] and the rate of live birth (47.19% vs. 30.19%, P=0.005) were significantly increased in the intervention group compared with the control group. Among obese patients, live births [(0.89±3.79) vs. (0.48±3.69), P=0.040] and the rate of live birth (64.29% vs. 37.93%, P=0.047) were significantly increased in the intervention group. Conclusion:In overweight and obese infertile patients undergoing FET cycle, the nutritional intervention of CRD combined with complex intestinal microecological preparation can help reduce weight and body fat, and may be beneficial to improving the success rate of assisted reproductive technology.

Recovery of proprioception after lateral ankle sprain / 中国康复理论与实践

ObjectiveTo observe the recovery of proprioception of the affected ankle over time after lateral ankle sprain accepting routine rehabilitation. MethodsFrom June, 2020 to June, 2022, 18 patients with lateral ankle sprain in Kunshan Rehabilitation Hospital underwent routine rehabilitation for twelve weeks. They were measured active and passive position sense of bilateral ankles using an isokinetic dynamometer before treatment, and four, eight and twelve weeks after treatment, respectively. ResultsThe active presentation difference of affected ankle reduced after treatment (F = 22.533, P < 0.001), but it was more than that of the healthy ankle at the same time (t > 4.419, P < 0.001). No significant improvement was found in passive presentation difference of affected ankle after treatment (F = 1.175, P > 0.05), and it was not significantly different from those of the healthy ankle at the same time (|t| < 0.646, P > 0.05). ConclusionProprioception of affected ankle has been impaired after lateral ankle sprain, and it can be recovered after rehabilitation, but cannot achieve the healthy level even after three months of training. Passive position sense as an index of proprioception needs more researches.

Acupuncture point selection for prevention and treatment of generalized anxiety disorder from the perspective of Microbiota-Gut-Brain Axis / 国际中医中药杂志

Disorders of the gut flora (GF) affect the level of 5-hydroxytryptamine (5-HT) in the brain of patients with generalized anxiety disorder (GAD) and influence the development of the disease. Most of the acupuncture points selected for GAD are based on the principles of local acupuncture points and acupuncture points following the distant channels of the meridians, regarding Baihui (DU 20), Fengchi (GB 20), and Yintang (GV 29) as the main acupuncture points, and the acupuncture points selected for the regulation of GF are Zhongwan (CV 12), Tianshu (ST 25), and Guanyuan (RN 4) and Zusanli (ST 36). Recently, many studies have been conducted on the mechanism of action of acupuncture in the treatment of GAD from the perspective of GF, but few have investigated the theoretical of acupuncture points used to prevent and treat GAD. This paper discusses the theoretical basis of acupuncture to regulate the "microbiota-gut-brain axis" (MGBA) for the prevention and treatment of GAD, and proposes the method of "regulating the internal organs and calming the mind and relieving anxiety" through analyzing the researches on the regulation of GF and GAD.

Clininal evaluation of a novel China original liquid pulsation system for meibomian gland dysfunction / 中华实验眼科杂志

Objective:To evaluate the efficacy and safety of a China original liquid pulsation system for the treatment of meibomian gland dysfunction (MGD).Methods:A non-randomized controlled clinical trial was conducted.Twenty-two patients (44 eyes) diagnosed with MGD in Eye and ENT Hospital of Fudan University from February to August 2022 were enrolled.The patients were assigned into two groups according to their willingness.Of the 22 patients (44 eyes), 10 patients (20 eyes) in single liquid pulsation system group were treated with single liquid pulsation system for 12 minutes, and 12 patients (24 eyes) in intense pulsed light (IPL) group were treated with a course (4 times) of IPL, warm compresses and meibomian gland massage at three-week intervals.There was no difference in age and other baseline clinical indexes between the two groups (all at P<0.05). The meibum grading, quality grading of tear film lipid layer, Symptom Assessment Questionnaire in Dry Eye (SANDE) questionnaire score, first and average tear breakup time (BUT), corneal fluorescein sodium staining (CFS) score, tear meniscus height (TMH), and the area of meibomian gland loss were determined at baseline, 1 and 3 months after treatment.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Eye and ENT Hospital of Fudan University (No.2021069). Written informed consent was obtained from each patient before any medical examination. Results:Statistically significant group effects and time effects were found in the quality of tear film lipid layer ( Hgroup=4.39, P=0.036, Htime=6.30, P=0.043) and average BUT ( Fgroup=4.41, P=0.038; Ftime=4.08, P=0.049) in the two groups.The meibum grading, first BUT and TMH 1 and 3 months after treatment were significantly better than before treatment in single liquid pulsation system group (all at P<0.05). Compared with before treatment, there was no significant improvement in the meibum grading, distribution of tear film lipid, first BUT and TMH at 1 and 3 months after treatment in IPL group (all at P>0.05). In both groups, the SANDE and CFS scores 1 and 3 months after treatment were better than those before treatment, showing statistically significance (all at P<0.05). In terms of safety, neither instrument-related adverse events nor extra complaints of discomfort were reported in the single liquid pulsation system group.In both groups, the number of patients with positive CFS staining significantly decreased, and no new cases with positive CFS appeared after treatment. Conclusions:This China original liquid pulsation system is a safe and effective physical therapy in improving tear film dysfunction and ocular surface symptoms of MGD patients within 3 months after treatment.
