Clinicopathological characteristics and endoscopic treatment efficacy of de novo early colorectal cancer / 中华消化内镜杂志

Objective:To analyze the clinicopathological features of de novo early colorectal cancer and to evaluate the efficacy of endoscopic treatment.Methods:Patients with de novo early colorectal cancer who underwent endoscopic resection in Beijing Friendship Hospital, Capital Medical University from June 2020 to May 2022 were enrolled. The baseline data, endoscopic manifestations, treatment methods, postoperative pathological results and prognosis of the patients were collected retrospectively.Results:A total of 33 patients with de novo early colorectal cancer were enrolled with the age of 62.67 ± 8.62 years, and the male to female ratio was 7.25∶1. The long diameter of lesions was 0.96 ± 0.36 cm. The lesion morphology was mainly superficial phenotype (type 0-Ⅱ), accounting for 72.7% (24/33). Endoscopic submucosal dissection (ESD) was performed in 29 cases and endoscopic mucosal resection (EMR) was performed in 4 cases. Postoperative pathology showed that 11 cases (33.3%) were well differentiated tubular adenocarcinoma, of which the superficial submucosal layer was invaded in 2 cases. Twenty cases (60.6%) were moderately differentiated tubular adenocarcinoma, of which the superficial submucosa layer was invaded in 5 cases and the deep submucosa layer in 15 cases. Two cases (6.1%) were moderately-poorly differentiated tubular adenocarcinoma, where the deep submucosa layer was invaded in both. There was significant correlation between the depth of invasion and the degree of differentiation ( P<0.001), and moderately and moderately-poorly differentiated lesions were more likely to invade the deep submucosa layer. The en bloc resection rate was 100.0% (33/33), the complete resection rate was 97.0% (32/33), and the curative resection rate was 42.4% (14/33). Among the 19 patients who did not achieve curative resection, 13 patients received supplementary surgical treatment. No tumor residue or lymph node metastasis was found in the postoperative pathology. All patients were followed up for 3-25 months, and no signs of local recurrence or metastasis were found. Conclusion:Most de novo early colorectal cancers are superficial phenotype under endoscopy. The pathology is mainly moderately differentiated tubular adenocarcinoma. Endoscopic resection of de novo early colorectal cancer shows encouraging short-term efficacy.

Evaluation of neutrophil/lymphocyte ratio and the end-stage liver disease-sodium model in predicting short-term prognosis of patients with HBV-related acute-on-chronic liver failure / 中华全科医师杂志

Objective:To evaluate neutrophil/lymphocyte ratio(NLR) and the model for end-stage liver disease-sodium(MELD-Na)score in predicting short-term prognosis of patients with HBV-related acute-on-chronic liver failure(HBV-ACLF).Methods:A total of 234 consecutive HBV-ACLF patients(194 males and 40 females, aged 23-85 years)admitted to Hangzhou Xixi Hospital from January 2019 to December 2021 were enrolled. According to the 12-week clinical outcomes, patients were divided into good prognosis group( n=141)and poor prognosis group( n=93). Univariate and multivariate Logistic regression were performed to identify independent risk factors for poor prognosis of HBV-ACLF patients. Receiver operating characteristics(ROC)curve was applied to evaluate the accuracy of risk factors in predicting short-term prognosis of HBV-ACLF patients. Results:The age [(48.7±11.9) vs. (52.5±9.9) years old, t=-2.59, P=0.011], proportion of males [78.0%(110/141) vs. 90.3%(84/93), χ2=5.99, P=0.014], total bilirubin[202.9(141.2, 287.6) vs. 320.0(224.4, 400.0) μmol/L, Z=-5.14, P<0.001], creatinine [71.0(59.0, 78.0) vs. 81.0(64.0, 111.0)μmol/L, Z=-3.98, P<0.001], international normalized ratio[1.66(1.52, 1.86) vs. 1.91(1.66, 2.27), Z=-5.46, P<0.001], leukocyte count[5.16(3.99, 6.95)×10 9/L vs. 6.57(4.83, 8.30)×10 9/L, Z=-4.14, P=0.001], NLR[2.77(2.02, 3.55) vs. 5.48(3.44, 8.53), Z=-8.48, P<0.001], MELD score[22.0(20.0, 24.0) vs. 26.0(24.0, 29.0), Z=-9.22, P<0.001], MELD-Na score[22.8(20.0, 25.6) vs. 29.0(25.0, 36.0), Z=-9.16, P<0.001], liver cirrhosis[77.3%(109/141) vs. 88.2%(82/93), χ2=4.41, P=0.036], hepatorenal syndrome[4/141(2.8%) vs. 12/93(12.9%), χ2=8.91, P=0.003] and the proportion of artificial liver treatment[21/141(14.9%) vs. 24/93(25.8%), χ2=4.30, P=0.038] were significantly elevated in poor prognosis group compared with survival group. Logistic regression analysis showed that NLR( OR=3.76, 95 %CI: 2.10-6.74, P<0.001)and MELD-Na score( OR=2.24, 95 %CI: 1.17-4.29, P=0.015) were independent risk factors for poor short-term prognosis of HBV-ACLF patients. The area under the ROC curve(AUC)of NLR, and MELD-Na for the short-term prognosis of HBV-ACLF patients was 0.792 and 0.822, respectively. The AUC of the combination of NLR with MELD-Na was 0.858, which was significantly higher than that of NLR( Z=-3.04, P=0.001) or MELD-Na score( Z=-2.16, P=0.031)alone. Based on the cut-off value of the combined model, patients were classified into high combined model score (≥0.04) group and low combined model score (<0.04) group, the survival rate of the high group was significantly higher than that of the low group( χ2=67.47, P<0.001). Conclusions:NLR and MELD-Na score are independent risk factors of the short-term prognosis of HBV-ACLF patients. The combination of NLR and MELD-Na score will be beneficial to predict the short-term prognosis of HBV-ACLF patients.

Novel Coronavirus Pandemic Impacts Children and Adolescents' Psychological Well-Being in Heavily Hit Chinese Provinces

AbstractsIn light of the novel coronaviruss (COVID-19s) threat to public health worldwide, we sought to elucidate COVID-19s impacts on the mental health of children and adolescents in China. Through online self-report questionnaires, we aimed to discover the psychological effects of the pandemic and its associated risk factors for developing mental health symptoms in young people. We disseminated a mental health survey through online social media, WeChat, and QQ in the five Chinese provinces with the most confirmed cases of COVID-19 during the late stage of the country-wide lockdown. We used a self-made questionnaire that queried children and adolescents aged 6 to 18 on demographic information, psychological status, and other lifestyle and COVID-related variables. A total of 17,740 children and adolescents with valid survey data participated in the study. 10,022 (56.5%), 11,611 (65.5%), 10,697 (60.3%), 6,868 (38.7%), and 6,225 (35.1%) participants presented, respectively, more depressive, anxious, compulsive, inattentive, and sleep-related problems compared to before the outbreak of COVID-19. High school students reported a greater change in depression and anxiety than did middle school and primary school students. Despite the fact that very few children (0.1%) or their family members (0.1%) contracted the virus in this study, the psychological impact of the pandemic was clearly profound. Fathers anxiety appeared to have the strongest influence on a childrens psychological symptoms, explaining about 33% of variation in the childs overall symptoms. Other factors only explained less than 2% of the variance in symptoms once parents anxiety was accounted for. The spread of COVID-19 significantly influenced the psychological state of children and adolescents. It is clear that children and adolescents, particularly older adolescents, need mental health support during the pandemic. The risk factors we uncovered suggest that reducing fathers anxiety is particularly critical to addressing young peoples mental health disorders in this time.

Clinical value of SpyGlass DS cholangioscopy in diagnosis and treatment of patients with biliary tract diseases (with video) / 中华消化内镜杂志

Objective To evaluate the clinical application value of SpyGlass DS cholangioscopy in diagnosis and therapy of patients with biliary tract diseases. Methods Seven patients with biliary tract diseases were examined and treated with SpyGlass DS system. Three patients with large choledocholithiasis underwent laser lithotripsy under SpyGlass DS system, and then the broken stones were removed by ERCP. Four patients with indeterminate bile duct stricture underwent SpyGlass DS examination and SpyGlass DS-guided biopsies if necessary.Results SpyGlass DS cholangioscopy was successfully performed in all patients with a mean procedure time of 12. 6 min. Complete stone clearance was achieved in 3 patients with large biliary stones. Of the 4 patients with indeterminate biliary stricture, 2 underwent SpyGlass DS-guided biopsies and were diagnosed as malignant biliary tumor; the other 2 patients were diagnosed as inflammatory bile duct stenosis after visualizing the target lesions without biopsy. Two patients developed hyperamylasemia after the procedure, and recovered spontaneously. Conclusion SpyGlass DS cholangioscopy can provide accurate diagnosis in indeterminate biliary strictures and facilitate therapy in patients with challenging biliary stones.

The relationship between smoking status and epidermiology of asthma in people aged over 14 years in China / 中华内科杂志

Objective To study the relationship between bronchial asthma and smoking status in Chinese people.Methods Asthma epidemiological survey and stratified-cluster-random method survey were performed in residents over 14 years in 8 provinces (cities) of China from February 2010 to August 2012.Asthma was diagnosed based upon case history,clinical signs and lung function test.Smoking status was investigated by questionnaire.Results Sampling population was 180 099 and 164 215 were valid.A total of 2 034 subjects were diagnosed as asthma including 79 692 men and 84 523 women.The overall prevalence rate of asthma was 1.24％ (2 034/164 215).Smokers were 23.8％ (39 137/164 215) in the whole population.Smokers were 34.5％ (702/2 034) in asthmatic patients,compared with 23.7％ (38 435/ 162 181) in no-asthmatic population.The incidence of asthma was 1.79％ and 1.06％ in smokers and nonsmokers respectively (P ＜0.001),suggesting that OR of smoking was 1.70 (95％ CI 1.55-1.86,P ＜ 0.001).According to asthma control test (ACT) score,the level of asthma control in non smoking group was higher than that in smoking group(43.2％ vs 35.3％).The times of hospitalization due to acute exacerbations (0.51 vs 0.41 events/person/year),total hospitalization rate (27.35 ％ vs 20.12％),annual emergency room visits (0.80 vs 0.60 events/person/year) and emergency room visit rate (31.77％ vs 24.47％) were all much higher in smoking asthmatic patients than those in non smoking asthmatic patients,indicating that the level of asthma control in smoking patients was significantly worse than in non smoking patients.Conclusions The smoking rate in Chinese people over 14 years is still high.The prevalence rate of asthma in smokers is significantly higher than that of non-smokers.The level of asthma control in smokers is significantly worse than that in non smokers.

Chinese expert consensus for non-antiinfective effects and clinical use of macrolides / 中华内科杂志

Important/potential value of macrolides has been proved in the management of chronic respiratory diseases by increasing basic and clinical trials.Through three face-to-face discussions,10 experts examined important data and drafted this consensus related to macrolides:(1) mechanism of nonantiinfective effects;(2) clinical use in chronic respiratory diseases;(3) cautions of long-term use.The mechanism out of non-antiinfective effects includes anti-inflammatory effect,modifying airway secretion,immune-regulation related to antibacterial effect,corticoid saving effect and anti-viral effect.The efficacy of long-term use of low-dose macrolides is definitely confirmed in diffuse panbronchiolitis,chronic rhinosinusitis.It is considerably used in bronchiectasia,cystic fibrosis,severe asthma and chronic obstructive pulmonary disease.Further studies should be conducted in cryptogenic organizing pneumonia and respiratory viral infection.It should be paid attention to its possible adverse effects (including drug interactions,cardiac toxicity,ototoxicity and disturbance of intestinal flora) and drug resistance in long-term use.A Chinese consensus for non-antiinfective effects and clinical use of macrolides is developed for the first time,which aims to expand their rational use and the further research.

Laparoscopic-assisted vaginoplasty by using sigmoid colon and peritoneum for congenital complete colpatresia / 局解手术学杂志

Objective To study the desired therapeutic effect of vaginoplasty using sigmoid colon or peritoneum for entire vaginal atre-sia.Methods From May 2015 to October 2015,8 patients with complete vaginal atresia in our hospital performed vaginoplasty using sigmoid colon or peritoneum successfully.The operation methods,prognosis and therapeutic effect and quality of sexual life of two groups were com-pared and analyzed to investigate a perfect operative method and ideal nursing.Results Laparoscopic vaginoplasty using the peritoneum compared with that using sigmoid colon has advantages of shorter time of operation,less bleeding,less trauma and quicker recovery.However, artificial vagina using sigmoid colon was much more similar to a natural vagina in morphological and physiological characteristics,merely ac-companied by excessive mucus discharge during the postoperative period.At lower risk of vaginal adhesion and stenosis,laparoscopically as-sisted vaginoplasty using sigmoid colon graft also puts high technical requirements.Two patients normally developed uterus menstruate regular-ly.Four patients without uterus and 2 patients with rudimentary uterus experienced good sexual intercourse after vaginoplasty.Conclusion Patients with complete colpatresia who have normal womb should creat a patent and functional vagina until adolescence to restore its physio-logical and reproductive function.Anatomical reconstructive treatment of vaginal agenesis for patients with absent or hypoplastic uterus can be postponed till the late teens or in the adult.Both laparoscopic sigmoid vaginoplasty and peritoneal vaginoplasty achieve a minimal-invasive, cosmetic,natural lubricous, smooth artificial vagina for patient’ s sex life satisfactory.

Endoscopic management of large common bile duct stones / 临床肝胆病杂志

With the development of endoscopic techniques in recent years,therapeutic endoscopic retrograde cholangiopancreatography has replaced surgery as the first approach to the extraction of common bile duct stones.Endoscopic sphincterotomy and endoscopic papillary bal-loon dilation have become established endoscopic techniques for stone removal.However,it remains a challenge for endoscopists to remove large common bile duct stones.Emerging endoscopic modalities,such as endoscopic papillary large balloon dilation and cholangioscopy-guided laser or electrohydraulic lithotripsy,have been shown to be safe and effective for management of large common bile duct stones.This paper reviews recent advances in the endoscopic management of large common bile duct stones.

A survey of knowledge on common cold and its treatment situation among physicians from various levels of hospitals in mainland China / 中华内科杂志

Objective To investigate the cognition of the common cold and current situation of the treatment among physicians from various levels of hospitals in Chinese mainland,so as to provide evidence for future continuing medical education and rational medication.Methods A questionnaire designed for this survey was used to learn about the general information,cognitive degree of the common cold and prescription habits of physician who prescribed for cold within last three months,from various levels hospitals.Results A total of 1001 physicians were interviewed.Among them,749 physicians chose right options that the cold was the common cold and the influenza with 79.84％ in resident physicians and 56.76％ in chief physicians.A total of 745 physicians chose options that the course of common cold will be lasting 4 to 7 days; 895 physicians chose options that old people are the most susceptible for complication; 669 physicians thought the common cold was the most common infection in winter; 841 physicians used clinical methods to diagnose the common cold; 736 physicians thought although the cold was a kind of self-limited disease and symptomatic treatment could alleviate symptoms and improve life quality,patients should see doctor in time if it turns to severer; and 745 physicians held the opinion that treatment of the common cold should focus on relieving symptoms first. In addition, 61.60％ physicians had made prescription based on clinical symptoms; 505(54.24％ ) of them thought compound drugs were priority in treating the common cold.However,there were still 43 physicians prescribed antibiotics for common cold.Conclusions There is misunderstanding and discrepancy in cognition towards common cold and treatment among physicians from various levels of hospticals in mainland China.Physicians should standardize diagnosis and treatment for the common cold according to the domestic and foreign guidelines.

A survey of knowledge on common cold in outpatient clinics / 中华内科杂志

Objective To investigate outpatients' cognition towards common cold and their habituated medication so as to provide evidence for future public healthcare education.Methods Patients who attended hospital for diagnosis and treatment of common cold at least within past three months were asked to fill a questionnaire independently so as to learn their cognition towards common cold and medication habit.Results Among the patients underwent survey,52.2 ％ had incorrect knowledge about common cold; 2.99％ didn't know about the hazards of common cold; 34.80％ couldn't distinguish common cold from influenza; 30.07％ considered common cold couldn't get relief without treatment; 68.24％ didn't know about the proper effects of influenza vaccination; 6.4％ often took oral medicine even intravenous injection when they caught a common cold; 59.77％ often took medication from drugstore without prescription by doctor,and a few asked doctors to prescribe medicine on their request; 9.42％ didn't know about the side effects of drug for cold treatment; and 9.72％ didn't know about the active ingredients of drug for cold treatment.There were significant differences in the common cold cognition among population of different ages and education background.The older or the higher education status patients had a better cognition ( P ＜0.0 ).Conclusion There exist a certain degree of wrong cognition towards common cold among patients of different literacy degree and different age. Public health education on common cold need to be further strengthened.

The Diagnostic Value of the Fractional Exhaled Nitric Oxide for Asthma / 中国呼吸与危重监护杂志

Objective To determine the diagnostic value of fractional exhaled nitric (FeNO) measurement in diagnosis of bronchial asthma. Methods The patients with unkown-cause respiratory symptoms including wheezing, cough, and breathlessness were enrolled from August to September in 2008. FeNO was measured by nitric oxide analyzer (NIOX; Aerocrine AB; Solna, Sweden). Bronchial challenge test (BCT) or bronchodilator test was defined as golden standard for asthma diagnosis. The value of FeNO was assessed and the optimal operating point of FeNO testing was determined by the means of the receiver operating characteristic (ROC) curves. Results A total of 101 patients were enrolled, in which 48 cases were diagnosed as asthma by positive yield in BCT (in 38 cases) or bronchodilator test (in 10 cases). The severity of airway hyperresponsiveness (AHR) judged by BCT was mild in 15 cases, moderate in 15 cases and severe in 8 cases. The levels of FeNO of asthma group were higher than those of non-asthma group [(68.19±43.00) pph vs (19.52±10.60) ppb, P < 0.05]. A linear correlation of FeNO with lnPD20 FEV1 was revealed in the cases with AHR. Area under ROC curve was 0.9. The optimal diagnostic cutoff point was 36.5 ppb which was capable of differentiating asthma and non-asthma with sensitivity of 92.7%, specificity of 83.3%, positive predictive value of 79.17% , negative predictive value of 94.34% and accuracy of 87.13%. Conclusion FeNO test may be helpful in the diagnosis of asthma with high sensitivity and specificity.
