ABSTRACT
ObjectiveTo investigate the application value of liver/spleen CT value （CTL/S）， controlled attenuation parameter （CAP）， and magnetic resonance imaging-proton density fat fraction （MRI-PDFF） in chronic hepatitis B （CHB） patients with hepatic steatosis. MethodsA retrospective analysis was performed for the clinical data of 213 CHB patients who underwent liver CT， CAP， and MRI-PDFF examinations in Affiliated Hospital of Yan’an University from October 2018 to December 2022. According to MRI-PDFF， the 213 patients were divided into CHB group with 111 patients （MRI-PDFF<5%） and CHB+hepatic steatosis group with 102 patients （MRI-PDFF≥5%）， among whom there were 69 patients with mild hepatic steatosis and 33 patients with moderate to severe hepatic steatosis. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The Bland-Altman plot was used to evaluate the consistency in MRI-PDFF measurement between two physicians. The Spearman’s correlation coefficient was used to analyze the correlation between CTL/S and MRI-PDFF and between CAP and MRI-PDFF. The receiver operating characteristic （ROC） curve was plotted and the area under the ROC curve （AUC） was calculated to investigate the value of CTL/S and CAP in the diagnosis of different degrees of hepatic steatosis， and the DeLong test was used to compare the AUCs of the two radiological examinations. ResultsMRI-PDFF had relatively high repeatability and stability in CHB patients. There is a significant negative correlation between CTL/S and MRI-PDFF （r=-0.800， P<0.001） and a significant positive correlation between CAP and MRI-PDFF （r=0.692， P<0.001）. Both CTL/S and CAP had a relatively high accuracy in the diagnosis of hepatic steatosis in CHB patients， with an AUC of 0.951 and 0.902， respectively， and CTL/S had a better accuracy than CAP （P<0.05）. In the diagnosis of mild and moderate-to-severe hepatic steatosis， CTL/S had an AUC of 0.921 and 0.895， respectively， and CAP had an AUC of 0.859 and 0.825， respectively， suggesting that CTL/S had a slightly higher diagnostic efficiency than CAP. ConclusionMRI-PDFF has high repeatability and stability in CHB patients， and CTL/S and CAP have a high diagnostic value for different degrees of hepatic steatosis in CHB patients.
ABSTRACT
OBJECTIVE To investigate the current situation of pharmaceutical clinic service in medical institutions in China and provide experience and suggestions for promoting the development of pharmaceutical clinics. METHODS Questionnaire survey was used to investigate the development of pharmaceutical clinics in medical institutions of 31 provinces （autonomous regions and municipalities directly under the central government） in March to April 2023， and the descriptive analysis was conducted. The regression analysis was carried out for the influential factors of pharmaceutical clinic service. RESULTS A total of 1 368 questionnaires were distributed in this survey and 1 304 valid questionnaires were collected with the effective response rate of 95.32%. A total of 463 medical institutions carried out pharmaceutical clinic service， the rate of which was 35.51% （463/1 304）； the rates of pharmaceutical clinics in tertiary， secondary， primary and other medical institutions were 52.80%， 17.18% and 5.88%， respectively. The frequency of opening pharmaceutical clinics was 3.17 days per week on average， with an average of 5.99 visiting pharmacists in each medical institution. Among the visiting pharmacists， clinical pharmacists accounted for the vast majority （88.68%， 2 459/2 773）. There were various categories of pharmaceutical clinics， including joint clinics and pharmacist-independent clinics； among pharmacist-independent clinics， pharmaceutical specialty/specialty disease clinics were the main ones， accounting for 89.72% of the total number of pharmaceutical clinics. The value of pharmacists in pharmaceutical clinics was manifested in various forms， among which the proportion of medical institutions charging pharmaceutical clinics was 10.80%. The main experiences in developing pharmaceutical clinics were to attach importance to discipline construction and personnel training. The main difficulties in developing pharmaceutical clinics were low compensation levels and a shortage of talent.The number of clinical pharmacists， the number of visiting pharmacists in pharmaceutical clinics and additional compensation were positively correlated with the amount of pharmaceutical clinic services（P＜0.05）. CONCLUSIONS In recent years， pharmaceutical clinics have made significant progress； in the future， it is still necessary to further strengthen discipline construction and talent cultivation， pay attention to the value embodiment of pharmacists， to promote the healthy development of pharmaceutical clinics.
ABSTRACT
Influenza virus causes serious threat to human life and health. Due to the inherent high variability of influenza virus, clinically resistant mutant strains of currently approved anti-influenza virus drugs have emerged. Therefore, it is urgent to develop antiviral drugs with new targets or mechanisms of action. RNA-dependent RNA polymerase is directly responsible for viral RNA transcription and replication, and plays key roles in the viral life cycle, which is considered an important target of anti-influenza drug design. From the point of view of medicinal chemistry, this review summarizes current advances in diverse small-molecule inhibitors targeting influenza virus RNA-dependent RNA polymerase, hoping to provide valuable reference for development of novel antiviral drugs.
ABSTRACT
Understanding the research methods for drug protein targets is crucial for the development of new drugs, clinical applications of drugs, drug mechanisms, and the pathogenesis of diseases. Cellular thermal shift assay (CETSA), a target research method without modification, has been widely used since its development. Now, there are various CETSA-based technology combinations, such as mass spectrometry-based cellular thermal shift assay (MS-CETSA), isothermal dose response-cellular thermal shift assay (ITDR-CETSA), amplified luminescent proximity homogeneous assay-cellular thermal shift assay (Alpha-CETSA), etc., which combine their respective advantages and further expand the application scope of CETSA. These technologies are suitable for the entire drug development chain, from drug screening to monitoring the target binding and off-target toxicity of drugs in patients. Based on the author's research experience, this paper reviews the principles of CETSA and related binding technologies, their application in target discovery, and the progress of data processing and analysis in recent years, aiming to provide reference and reference for the further application of CETSA.
ABSTRACT
@#Objective To study the relationship between preoperative heart rate variability (HRV) and postoperative atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCAB). Methods A retrospective analysis was performed on the clinical data of 290 patients who were admitted to the Department of Cardiovascular Surgery, General Hospital of Northern Theater Command from May to September 2020 and received OPCAB. There were 217 males and 73 females aged 36-80 years. According to the incidence of POAF, the patients were divided into two groups: a non-atrial fibrillation group (208 patients) and an atrial fibrillation group (82 patients). The time domain and frequency domain factors of mean HRV 7 days before operation were calculated: standard deviation of all normal-to-normal intervals (SDNN), root mean square of successive differences, percentage difference between adjacent normal-to-normal intervals that were greater than 50 ms, low frequency power (LF), high frequency power (HF), LF/HF. Results The HRV value of patients without POAF was significantly lower than that of patients with POAF (P<0.05). The median SDNN of the two groups were 78.90 ms and 91.55 ms, respectively. Age (OR=3.630, 95%CI 2.015-6.542, P<0.001), left atrial diameter (OR=1.074, 95%CI 1.000-1.155, P=0.046), and SDNN (OR=1.017, 95%CI 1.002-1.032, P=0.024) were independently associated with the risk of POPAF after OPCAB. Conclusion SDNN may be an independent predictor of POAF after OPCAB.
ABSTRACT
OBJECTIVE To systematically evaluate the efficacy and safety of glucokinase activators in the treatment of type 2 diabetes mellitus. METHODS PubMed， Cochrane Library， Web of Science， Embase and CNKI databases were searched from the inception to March 2022. Randomized controlled trials about glucokinase activators versus placebo （or other oral hypoglycemic agents） in the treatment of type 2 diabetes were included， data were extracted and meta-analysis was analyzed using RevMan 5.4 software. RESULTS A total of 9 studies with 215 0 patients were included. In terms of hypoglycemic effect， compared with control group， glucokinase activators significantly reduced glycosylated hemoglobin （HbA1c） [MD＝－0.40， 95%CI（－0.53， －0.26）， P＜0.000 01]， fasting blood glucose[MD＝－0.53， 95%CI（－0.85， －0.20）， P＝0.001] and 2 h postprandial blood glucose [MD＝－2.28， 95%CI（－2.68， －1.88）， P＜0.000 01] in diabetic patients. In terms of safety， the incidence of hypoglycemia caused by glucokinase activators was higher than control group on the whole [RR＝1.55， 95%CI（1.20，2.01）， P＝ 0.000 8]. According to the subgroup analysis of organs activated by glucokinase activator， the incidence of hypoglycemia in the pancreas-liver dual activator group [RR＝1.44， 95%CI（1.11，1.89）， P＝0.007] and liver-selective activator group [RR＝2.26， 95%CI（1.02，5.03）， P＝0.05] was higher than that in the control group， the difference was statistically significant. CONCLUSIONS Glucokinase activators can effectively reduce HbA1c， fasting blood glucose and 2 h postprandial blood glucose in patients with type 2 diabetes， but the risk of hypoglycemia remains to be addressed.
ABSTRACT
Objective:To explore the process of regression of the hyaloid vessels and development of retinal vessels in C57BL/6J mice and the relationship between them.Methods:Seventy-five healthy SPF C57BL/6J mice on postnatal day 1 (P1) were selected and divided into control group (65 mice) and oxygen-induced retinopathy (OIR) model group (10 mice) by the random number table method.No treatment was given to control group.Mice in OIR model group were continuously fed in (75±3)% oxygen for 5 days from P7 and in normoxic condition for 5 days from P12.In control group, 5 mice were randomly selected and killed from P1 to P12 and P17, and the eyeballs were collected.In OIR model group, 5 mice were randomly selected and killed on P12 and P17, and the eyeballs were collected.The number of hyaloid arteries (HA), vasa hyaloidea propria (VHP), and tunica vasculosa lentis (TVL) of mice at different time was observed with a microscope.Another 5 adult mice aged 15 months old were selected to detect the vitreous vasculature using optical coherence tomography.The relationship between retinal astrocytes and retinal vascular development, VHP was observed by immunofluorescence staining.This study was approved by the Ethics Committee of Nankai Hospital (No.NKYY-DWLL-2021-070). The use and care of experimental animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals and the ARVO statement.Results:In control group, HA did not degenerate rapidly during eyeball development, which still presented even 15 months after birth.The number of VHP reduced rapidly from P4 to P8, and tended to be stable at 2.33±1.32 on P10 and 1.80±0.92 on P17.The number of TVL reduced rapidly from P5 to P9, reduced to 2.30±1.42 on P10, with most of the TVL blood vessels being transparent without blood supply, and decreased to 0.30±0.48 on P17.Under the guidance of astrocytes, the retinal vessels of mice grew from the optic disc to the peripheral retina from P1 to P8, forming the primary retinal vascular layer.During the development of retinal superficial vessels, VHP showed synchronous regression and the decreased density and thinner diameter in the area covered by retinal vessels.VHP detached from the retina when retinal vessels developed to the peripheral retina, and there was no structural overlap between astrocytes and VHP.In OIR model group, the number of VHP increased from 2.14±0.90 on P12 to 4.60±1.35 on P17 and the number of TVL increased from 2.90±1.55 on P12 to 5.80±1.75 on P17, showing statistically significant differences ( t=4.188, P<0.001; t=4.668, P<0.001). There was no significant difference in the number of VHP and TVL between the two groups on P12 ( t=0.429, P=0.232; t=1.116, P=0.134). The number of VHP and TVL were significantly larger in OIR model group than in control group on P17 ( t=5.422, 9.574; both at P<0.001). Conclusions:In the vitreous vascular system of mice, the regression of VHP and TVL tends to be stable 10 days after birth, and the regression of HA was not obvious.The normal regression of vitreous vessels in mice depends on the normal development of retinal vessels and astrocytes.Retinal hypoxia delays vitreous vascular regression.
ABSTRACT
The impairment of optic disc and retinal function caused by intraocular pressure is one of the main causes of irreversible visual impairment.In addition to the effects of intraocular pressure, studies have found that ocular adduction and horizontal abduction movements affect the optic disc and surrounding retinal tissue, which result in mechanical pressure and traction having influences on tissue and this change is related to the rotation angle, speed, and age, etc.Studies have found that horizontal eye movements can cause changes in the nasal and temporal sides of the optic disc, as well as the surrounding retinal and choroidal structures, and these changes vary among different age groups.This paper reviewed the current research on the effects of horizontal eye movements on the morphology of the optic nerve and retina, in order to provide some useful clues for the treatment of relevant diseases in clinical practice.
ABSTRACT
Objective:To study the effects of patent ductus arteriosus (PDA) on bronchopulmonary dysplasia (BPD) in very low birth weight preterm infants (VLBWIs).Methods:From January 2018 to December 2020,VLBWIs hospitalized in NICU of our hospital were retrospectively analyzed.They were assigned into BPD group and non-BPD group according to whether BPD occurred. Clinical data including the severity of BPD , the diameter and duration of PDA and ibuprofen usage were analyzed. The predictive values of PDA diameter and duration for BPD were calculated using area under curve (AUC) of receiver operating characteristic curve (ROC) analysis.Results:A total of 173 VLBWIs were enrolled, including 42 in the BPD group and 131 in the non-BPD group. The incidence of hemodynamically significant PDA (hsPDA) in the BPD group was significantly higher than the non-BPD group (45.2% vs. 22.1%, P=0.001).hsPDA ( OR=2.806, 95% CI 1.307-5.745, P=0.005), PDA diameter ≥1.5 mm ( OR=7.003, 95% CI 1.323-48.884, P<0.001) and PDA duration >1 w ( OR=7.754, 95% CI 1.203-49.989, P=0.031) were all risk factors for BPD.As for the severity of BPD, hsPDA, PDA diameter ≥1.5 mm, PDA duration >1 w and FiO 2max >30% within 72 h after birth were risk factors for grade Ⅱ~Ⅲ BPD. The incidence of ibuprofen usage was significantly higher in grade Ⅱ~Ⅲ BPD group. If the diameter of PDA was 1.25 mm, the AUC was 0.806 (95% CI 0.706-0.906, P<0.001), sensitivity 82.6% and specificity 68.7% for grade Ⅱ~Ⅲ BPD. If the PDA duration was 10.5 d, the AUC was 0.821 (95% CI 0.718-0.925, P<0.001), sensitivity 65.2% and specificity 91.3%. Conclusions:hsPDA, larger PDA diameter and longer PDA duration are risk factors for the occurrence and severity of BPD in VLBWIs.
ABSTRACT
In the past 20 years, the multidisciplinary treatment model based on evidence-based medicine has significantly increased the rate of sphincter-preservation operation for rectal cancer. How to preserve rectum and anal function, avoid permanent colostomy, and improve post-operative quality of life of patients while ensuring radical resection of tumor, remains to be a key and hot topic in surgical treatment of rectal cancer. Based on literatures and clinical experiences, the authors summarize issues of sphincter preservation operation and comprehensive treatment, including intersphincteric resection, conformal sphincter preservation operation, total neoadjuvant therapy and radioimmunotherapy, for ultra-low rectal cancer, in order to provide reference for the colleagues.
ABSTRACT
Objective:To investigate the epidemiological characteristics of infant dyschezia in Xi′an city based on the Rome Ⅳ Criteria for Functional Gastrointestinal Disorders in Infants/Toddlers, and to analyze the related risk factors so as to provide epidemiological basis for clinical diagnosis and treatment.Methods:It was a cross-sectional survey conducted in the child health department of community health service center or hospital in Xi′an from October 2020 to October 2021 using the multi-stage cluster random sampling method.Infants aged 0-12 months were enrolled and their caregivers were interviewed by face-to-face electronic questionnaire.The prevalence and influencing factors of defecation difficulty in infants aged 0-9 months were analyzed according to the Rome Ⅳ Criteria for Functional Gastrointestinal Disorders in Infants/Toddlers.The prevalence of dyschezia in infants aged over 9 months was explored as well.The counting data were compared by Chi- square test.Univariable and multivariate Logistic regression analysis were performed to identify risk factors for dyschezia. Results:A total of 1 446 infants were collected, including 735 boys (50.8%) and 711 girls (49.2%), with an average age of (5.94±3.27) months.The prevalence of dyschezia aged 0-9 months in Xi′an was 3.46% (42/1 215), which gradually decreased with the increased age.Infants with dyschezia could defecate 2-3 times a day, or once a few days.Family history of defecation disorders ( OR=3.785, 95% CI: 1.912-7.494) was the risk factor for infant dyschezia, while complementary food ( OR=0.193, 95% CI: 0.075-0.495) was the protective factor for infant dyschezia ( P<0.05). Breastfeeding ( OR=8.126, 95% CI: 2.258-29.236) was the risk factor for dyschezia in infants who defecated less frequently ( P<0.05). Only 2 cases of 10-month-old infants had defecation-like symptoms, manifested as crying for a long time before defecation. Conclusions:The prevalence of dyschezia in infants aged 0-9 months in Xi′an is 3.46%.Dyschezia infants may also have a lower frequency of defecation.Timely addition of complementary food is beneficial to alleviate infant dyschezia, while infant who defecated less frequently are more likely to have dyschezia while breastfeeding.
ABSTRACT
Objective:To investigate the Correlation between ADC combined with serum C-reactive protein (CRP) and delayed encephalopathy after carbon monoxide poisoning (DEACMP), It provides scientific basis for early prediction of DEACMP.Methods:According to the design principle of case-control study, the data of acute carbon monoxide poisoning (ACOP) patients admitted to Shandong Provincial Hospital from December 2017 to December 2021 were retrospectively selected. Among them, patients with DEACMP were selected as the case group, without DEACMP were used as the control group. Univariate and multivariate analyses were performed on the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of ADC combined with CRP as a combined predictor for disease.Results:A total of 89 patients with ACOP were included, including 33 patients with DEACMP and 56 patients without DEACMP. There were no significant differences in gender, age, smoking, drinking, and underlying diseases (hypertension, coronary heart disease) between groups ( P>0.05). Logistic regression analysis showed that white blood cell count (WBC) ( OR=1.64, 95% CI: 1.19-2.26, P=0.003), CRP ( OR=1.22, 95% CI: 1.03-1.45, P=0.019) and ADC value of central semiovale white matter ( OR=0.99, 95% CI: 0.98-1.00, P=0.010) were associated with DEACMP in patients with ACOP. The ROC curve results showed that the area under the ROC of ADC combined with CRP in the center of semiovale was 0.765 (95% CI: 0.656-0.845), the specificity was 87.9%, the sensitivity was 23.2%, and the cut-off value was 3.5°. Conclusions:WBC, CRP and ADC value of central semiovale are independent factors for DEACMP. ADC value of central semiovale combined with CRP has more clinical value in the early diagnosis of DEACMP. For ACOP patients with DEACMP triggering factors, the diagnosis and treatment awareness of early screening of brain magnetic resonance imaging should be strengthened to avoid DEACMP.
ABSTRACT
Compared with traditional statistical models, machine learning in artificial intelligence has certain advantages in establishing predictive models. Currently, a large amount of research has been conducted on the application of machine learning in liver diseases. However, there is still no unified approach for selection of machine learning algorithms and steps of training different machine learning algorithms. As research progresses, predictive models based on machine learning combined with various omics have great potential in improving the diagnosis, treatment, and efficacy evaluation of liver diseases.
ABSTRACT
Objective:To investigate the outcome after laparoscopic radical surgery for colorectal cancer in patients over 80 years of age with preoperative combined type 2 diabetes (T2DM).Methods:Clinical data of 919 patients who underwent colorectal cancer laparoscopic resection surgery in Shaanxi Provincial People′s Hospital from January 2015 to January 2019 were retrospectively analyzed. The propensity score matching (PSM) method was used for 1∶1 matching of gender, ASA score, preoperative serum albumin level, body mass index(BMI), preoperative haemoglobin level, clinical tumour pathology TNM staging, tumour location, other medical comorbidities and history of abdominal surgery and finally group of 104 elderly diabetic patients aged ≥80 years with combined T2DM were successfully matched with another 104 non-elderly non-diabetic patients <80 years without combined diabetes group. (1) To compare the differences in operating time, intraoperative bleeding, number of intraoperative blood transfusions, number of lymph nodes dissected, number of ICU treatments, postoperative time to exhaustion and postoperative hospital stay, and postoperative adjuvant chemotherapy between the two groups after matching. (2)To observe the difference in major postoperative complications between the two groups. (3) Patients in both groups were observed for three years post-operative survival rate during the follow-up period. SPSS 25.0 statistical software was used for data analysis. The survival analysis was carried aut by the Kaplan-Meier curve method in parallel and the Log-Rank test.Results:Both groups were balanced in terms of baseline variable after PSM ( P>0.05). There was no difference between the two groups in terms of operative time, intraoperative bleeding, number of intraoperative blood transfusions, number of lymph nodes dissected, or time to postoperative evacuation ( P>0.05). There was a statistically significant difference between two groups in the number of people admitted to the ICU for treatment ( χ2=4.04, P=0.042), and ≥80 years diabetic group was higher. The difference in the incidence of postoperative complications between the two groups was not statistically significant [34.6% (36/104) vs 25.0% (26/104), χ2=2.30, P=0.130]; according to the Clavien-Dindo classification of postoperative complications, the incidence of Clavien-Dindo grade Ⅲ complications in the group ≥80 years with diabetes mellitus were was higher than that in the group <80 years without diabetes [12.5% (13/104) vs 4.8% (5/104), χ2=3.89, P=0.049]. For local surgical complications, the incidence of postoperative anastomotic leak was significantly higher in the ≥80 years diabetic group than in the <80 years non-diabetic group ( χ2=4.70, P=0.030), and the incidence of postoperative wound infection was no statistical significance in the two group. For non-surgical local complications, there was a statistically significant difference in pulmonary infection in the ≥80 years diabetic group compared to the <80 non-diabetic group ( χ2=4.68, P=0.031) and in acute coronary syndrome ( χ2=4.02, P=0.045). Compared with the <80 years non-diabetic group, patients in the ≥80 years diabetic group had significantly longer postoperative hospital stay [(13.3±4.4)d vs (9.2±3.2) d, t=3.41, P=0.019]. The difference in adjuvant chemotherapy after surgery between the two groups was not statistically significant (67.3% vs 76.0%, χ2=1.92, P=0.166). The survival rate at 3 years after surgery was not statistically significant in both groups [68.9% vs 74.2%, χ2=4.34, P=0.085]. Conclusions:The short-term and long-term outcomes of colorectal cancer in advanced age with type 2 diabetes are satisfactory. Adequate preoperative assessment of the patient's physical condition should be carried out, close intraoperative control of blood glucose, and close postoperative monitoring and regulation of blood glucose should be performed, except for patients with severe comorbidities and coexisting diseases that cannot tolerate surgery and advanced tumours that have lost their surgical significance.
ABSTRACT
Immunotherapy has become a common means of cancer treatment. In immunotherapy, PD-1/PD-L1 inhibitors have significant efficacy. Cancer and various opportunistic infections are common complications in patients with AIDS. Owing to the special immune situation of these patients, AIDS is regarded as an exclusion standard in most clinical trials for cancer immunotherapy, conferring immunotherapy difficulty in treating patients with AIDS. The popularity of effective antiretroviral drugs has prolonged the lifetime of people with AIDS. Therefore, exploiting the opportunity of using immunotherapy in AIDS with cancer is urgent.
ABSTRACT
Objective To investigate the gross alpha and gross beta radioactivity levels in drinking water around Shidao Bay Nuclear Power Plant before its operation. Methods Ten sampling sites were set up within 30 km of Shidao Bay Nuclear Power Plant. From 2018 to 2021, samples were collected during the dry season and wet season each year and were tested in a laboratory according to Standard examination methods for drinking water—radiological parameters (GB/T 5750.13—2006). Results From 2018 to 2021, the gross alpha radioactivity in drinking water within 30 km of Shidao Bay Nuclear Power Plant was within the range of about 0.004-0.420 Bq/L, which does not exceed the guided gross alpha radioactivity specified in the National Standard; from 2018 to 2021, the gross beta radioactivity level was about 0.008-1.050 Bq/L. In 2018, the gross beta radioactivity at the sampling site 4.7 km from the Nuclear Power Plant exceeded the guided level specified in the National Standards for Drinking Water Quality (GB 5749—2006), but it fell within the guided level in a repeat laboratory test after deducting the effect of 40K on the gross beta radioactivity. Conclusion After deducting the effect of 40K on the gross beta radioactivity, the gross alpha and gross beta radioactivity levels in drinking water within 30 km of Shidao Bay Nuclear Power Plant are within the guided levels specified in the National Standards.
ABSTRACT
The essence-qi-spirit theory is an important part of traditional Chinese medicine， whose steady state is the material and functional basis for the balance of yin and yang in the body， making the essence， qi and spirit integrated， and body and spirit harmonized. Based on this theory， it is proposed that essence and qi depletion， spirit dissipation and qi dispersion， disharmony between yin and yang is the main pathogenesis of sleep disorders. Therefore， the method of regulating and harmonzing yin and yang by essence gathering， qi nourishing and spirit storing can be used to treat sleep disorder. The biological clock system of the circadian rhythm of sleep is regulated by the molecular oscillation that is generated by the transcription of the biological clock gene， and is a clock gradually formed by orga-nisms constantly adapting to the laws of nature. As the material basis， power， and embodiment of sound and peaceful sleep， essence， qi and spirit can perceive and transmit natural signals， whose functions are similar to what is recognized by modern science that oscillation amplifies the rhythm signal， and synchronously regulates the expression signal of the biological clock gene， thereby forming a biological clock system with “input-oscillation-output” as the feedback cycle. It is believed that the regulation method of yin and yang by essence gathering， qi nourishing and spirit storing may comprehensively regulate the physiological activities through brain/ muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 （BMAL1）/circadian locomotor output cycles kaput （CLOCK）-period protein （PER）/ cryptochrome （CRY） transcriptional feedback loop， thereby adapting to the natural environment changes， playing an active role in the treatment of sleep disorders， and provideing a new idea for traditional Chinese medicine to reshape the molecular regulation system of the endogenous biological clock to prevent and treat sleep disorders.
ABSTRACT
Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.

Cox survival analysis model was used to analyze the individual, independent and joint association of depression symptoms and 10-year risk of ischemic cardiovascular disease with cardiovascular disease.@*RESULTS@#A total of 9 412 subjects were enrolled. The detection rate of depressive symptoms at baseline was 44.7%, and the 10-year middle and high risk of ischemic cardiovascular disease was 13.62%. During an average follow-up of 6.19 (6.19±1.66) years, 1 401 cases of cardiovascular disease were diagnosed in 58 258 person-years, revealing an overall incidence density of 24.048/1 000 person-years. After adjusting the factors, in terms of individual impact, the participants with depressive symptoms had a higher risk of developing CVD (HR=1.263, 95%CI: 1.133-1.408), while medium to high risk of ischemic cardiovascular disease had a higher risk of developing CVD (HR=1.892, 95%CI: 1.662-2.154). Among independent influences, participants with depressive symptoms had a higher risk of developing CVD (HR=1.269, 95% CI: 1.138-1.415), while medium to high risk of 10-year risk of ischemic cardiovascular disease had a higher risk of developing CVD (HR=1.898, 95%CI: 1.668-2.160). Joint impact result showed the incidence of cardiovascular disease in the low risk of 10-year risk of ischemic cardiovascular disease with depressive symptoms group, middle and high risk of 10-year risk of ischemic cardiovascular disease without depressive symptoms group, and 10-year middle and high risk of ischemic cardiovascular disease with depressive symptoms group were 1.390, 2.149, and 2.339 times higher than that of low risk of 10-year risk of ischemic cardiovascular disease without depressive symptoms (P < 0.001).@*CONCLUSION@#The superimposed depression symptoms of the middle and high-risk population at the 10-year risk of ischemic cardiovascular disease will aggravate the risk of cardiovascular disease in middle-aged and elderly people. In combination with the actual lifestyle intervention and physical index health management, attention should be paid to mental health intervention.

ISR is the most widely used anal-preserving operation for ultra-low rectal cancer. It can be divided into total ISR, subtotal ISR and partial ISR according to the resection range of internal sphincter. The advantage of ISR is that it can preserve the sphincter while ensuring the safety of oncology for ultra-low rectal cancer, representing the state of the art. However, it still needs to face the problem that the quality of life will decline due to poor postoperative anal function. The conformal sphincter-preserving operation (CSPO) is a functional anal-preserving surgery improved on the basis of ISR. It is superior to ISR in the postoperative anal function and patients' quality of life. So it can be a new choice for ultra-low rectal cancer.
