OBJECTIVE To study the effects of cy cloastragenol （CAG） on carbon tetrachloride （CCl4）-induced hepatic fibrosis（HF）and glycolysis in mice. METHODS Male ICR mice were randomly divided into blank group ，model group ，CAG low-dose，medium-dose and high-dose groups （60，120，240 mg/kg），with 6 mice in each group. Except that blank group was given olive oil intraperitoneally ，the mice in other groups were intraperitoneally injected with 10％CCl4-olive oil solution （5 mL/kg） three times a week for 8 weeks to induce HF model. From the 4th week after modeling ，mice in each drug group were given corresponding drug solution intragastrically （10 mL/kg），and mice in blank group and model group were given 0.5％ sodium carboxymethyl cellulose solution intragastrically （10 mL/kg），once a day for 4 weeks. During the experiment ，the body weight of mice were weighted ；after last gastrogavage ，the liver weight was weighted and liver indexes of mice were calculated. The changes of hepatic injury indexes [aspartate aminotransferase （AST）， alanine aminotransferase （ALT）]， related indexes of HF [hematoxylin-eosin （HE）staining score ，Masson and Picrosirius red staining collagen volume fraction ，collagen Ⅰ，α-smooth muscle actin （α-SMA）] and related indexes of glycolysis [lactic acid （LD），hexokinase（HK），phosphofructokinase（PFK）， pyruvate kinase （PK）] were all detected. RESULTS Compared with model group ，the collagen deposition and fibrosis of mice in each drug group were reduced ，and the body weights of mice （except for CAG low-dose group ）were increased to some extent （P＜0.05）. Liver indexes ，serum levels of ALT and AST ，HE staining score of liver histopathology ，Masson and Picrosirius red staining collagen volume fraction ，protein expression of collagen Ⅰ and α-SMA，serum content of LD ，the levels of HK ，PFK and PK in serum and hepatic tissues （except for hepatic tissue of CAG low-dose group ）were all decreased significantly （P＜0.05）. CONCLUSIONS CAG can improve HF in mice induced by CCl 4，and reduce the levels of key enzymes and products of glycolysis.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.

Objective    To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods    The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results    There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion    Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.

Objective:To explore the epidemic situation and brucellosis in key occupational populations of brucellosis monitoring sites in Jiangsu Province, and provide a basis for development of prevention and control strategies against brucellosis.Methods:From 2013 to 2017, according to the requirements of the "National Brucella Surveillance Programme", two brucellosis monitoring sites in Yixing City of Wuxi and Huaiyin District of Huai'an, Jiangsu Province were established to monitor brucellosis. Brucellosis epidemic data were collected and analyzed of the two monitoring sites in Yixing City and Huaiyin District from 2013 to 2017 (data were from Jiangsu Provincial Legal Infectious Disease Reporting System). Blood samples were collected from the general occupational populations (health check-up population) and the key occupational populations (people engaged in livestock trading, livestock slaughtering, and the fur, milk and meat processing) in the monitoring sites. Tiger red plate agglutination test (RBPT) and serum tube agglutination test (SAT) were used for serological examination. Results:From 2013 to 2017, a total of 18 cases of brucellosis were reported at the two monitoring sites in Yixing City and Huaiyin District, Jiangsu Province, including 13 males and 5 females, with a male to female sex ratio of 2.6∶1.0; the age of onset was mainly 35 - 64 years, accounting for 72.22% (13/18); the time of onset was mainly from January to June, accounting for 94.44% (17/18); and the occupational distribution was mainly farmers, accounting for 77.78% (14/18); there was no epidemic and outbreaks of brucellosis. A general occupational populations survey was conducted in 17 743 cases, serological tests were negative, no infection and no signs and symptoms were found in the two monitoring sites. In 2013 - 2017, a total of 113 cases of serological tests were positive in the key occupational populations of brucellosis in Jiangsu Province, with a positive rate of 7.83% (113/1 444), and the overall trend was downward year by year ( t = 6.463, P < 0.05). Among them, the positive rates in Yixing City and Huaiyin District were 11.79% (106/899) and 1.28% (7/545), respectively. The difference between different regions was statistically significant (χ 2 = 51.926, P < 0.01). The positive rates of occupational groups engaged in livestock trading, livestock slaughtering, and the fur, milk and meat processing were 5.10% (20/392), 9.74% (49/503), and 8.01% (44/549), respectively. The differences were statistically significant between different occupations (χ 2 = 6.618, P < 0.05); and the positive rates of livestock slaughtering occupations and the fur, milk and meat processing occupations were higher than that of livestock trading occupations ( P < 0.05). Conclusions:The positive rate of brucellosis in key occupational populations has showed a general downward trend, the livestock slaughtering occupations and the fur, milk and meat processing occupations are more susceptible to Brucella infection. It is still necessary to strengthen the health education for the key occupational populations of brucellosis and inspection and quarantine work for prevention of the epidemic of brucellosis in humans.

Objective:To explore the imaging features of 18F-fluorodeoxyglucose (FDG) PET/CT (high-resolution CT, HRCT) imaging in focal organizing pneumonia (FOP). Methods:Patients with solid nodular FOP ( n=45; 33 males, 12 females, age (58±9) years) and early peripheral non-mucinous solid lung adenocarcinoma ( n=47; 21 males, 26 females, age (63±10) years) confirmed by postsurgical pathology between May 2012 and December 2018 in Zhongshan Hospital, Fudan University were retrospectively analyzed. All patients underwent 18F-FDG PET/CT (HRCT) imaging followed by surgery within 3 weeks. The imaging findings and characteristics of the lesions were recorded. Differences of the maximum standardized uptake value (SUV max) and maximum diameter between FOP and adenocarcinoma were analyzed by Mann-Whitney U test or t′ test. Spearman correlation or Pearson correlation analysis was performed to analyze the relation between SUV max and maximum diameter. Binary logistic regression analysis was performed to identify the predictive factors for FOP. Finally, the receiver operating characteristic (ROC) curve analysis was used for evaluation of diagnostic efficiency. Results:The SUV max of FOP was lower than that of lung adenocarcinoma (3.1(1.7, 4.9) vs 6.5(3.8, 9.3); z=-4.598, P<0.01), and the maximum diameter of FOP was smaller than that of lung adenocarcinoma ((18.0±6.3) mm vs (21.8±4.3) mm; t′=-3.424, P<0.01). The SUV max was positively correlated with the maximum diameter in FOP group ( r s=0.509, P<0.01), while the SUV max of lung adenocarcinoma was not correlated with the lesion size ( r=0.076, P>0.05). HRCT of the PET/CT system showed the fusiform shape were more common in FOP ( χ2=9.549, P<0.05). Multivariate regression analysis identified that SUV max≤7.1, diameter≤18.3 mm, and fusiform shape were independent factors to predict FOP, with odds ratio ( OR) of 10.585, 4.674, 9.073, respectively (all P<0.05). ROC curve analysis showed that the area under the curve (AUC) of SUV max≤7.1 combined with diameter≤18.3 mm and fusiform nodule was 0.860, and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 97.8%(44/45), 70.2%(33/47), 75.9%(44/58), 97.1%(33/34), and 83.7%(77/92), respectively. Conclusion:SUV max≤ 7.1 combined with maximum diameter≤ 18.3 mm and fusiform shape may predict solid nodular FOP.

Objective: To describe and compare the epidemiology of Sepsis-1 and Sepsis-3 in Yuetan Subdistrict of Beijing, and to estimate the incidence of Sepsis-3 in China. Methods: A population-based cohort study was conducted. Through the database of Beijing Public Health Information System, the medical records of all adult residents hospitalized from July 1st, 2012 to June 30th, 2014 in Yuetan Subdistrict were reviewed. According to the clinical data of these patients, patients with Sepsis-1 and Sepsis-3 were enrolled in this analysis and the demographic characteristics of them were compared. Incidence and in-hospital mortality was calculated. Logistic regression method was used to analyze the risk factors of sepsis. Results: Compared with non-septic patients with infections, patients with Sepsis-1 or Sepsis-3 were more likely to be male, older, had more comorbidities and lower body mass index (BMI), had more lower respiratory tract infections, more intra-abdominal infections and more blood flow infections, but had fewer urogenital tract infections, fewer upper respiratory tract infections, fewer gastrointestinal infections and fewer skin and soft tissue infections, and had pure prognosis with longer length of hospital stay [days, Sepsis-1 compared with non-Sepsis-1: 18 (10, 34) vs. 14 (9, 22), Sepsis-3 compared with non-Sepsis-3: 20 (11, 39) vs. 14 (9, 25)] and higher mortality [Sepsis-1 compared with non-Sepsis-1: 20.6% (353/1 716) vs. 2.5% (44/1 733), Sepsis-3 compared with non-Sepsis-3: 32.0% (299/935) vs. 3.9% (98/2 514), all P < 0.01]. Logistic regression analysis showed that male, elder (age ≥ 65 years old), low BMI, bed-rest state, and combined with cerebrovascular disease and hematological malignancies were risk factors for Sepsis-1 [all odds ratio (OR) > 1, all P < 0.05], while the male, elder (age ≥ 65 years old), low BMI, bed-rest state, and combined with cerebrovascular disease, rheumatic immune disease, malignant diseases of blood system and dementia were risk factors for Sepsis-3 (all OR > 1, all P < 0.05). Sepsis-3 was more common in males [OR = 1.19, 95% confidence interval (95%CI) was 1.01-1.40, P < 0.05] and elderly patients (age 65-84 years old: OR = 1.60, 95%CI was 1.28-1.99, P < 0.01; age ≥ 85 years old: OR = 1.76, 95%CI was 1.39-2.23, P < 0.01) as compared with Sepsis-1. After adjusted for gender and age, the standardized incidence of Sepsis-1 was 461 per 100 000 person-year, and that of Sepsis-3 was 236 per 100 000 person-year, with the standardized mortality of 79 per 100 000 person-year and 67 per 100 000 person-year, respectively, in Yuetan Subdistrict of Beijing. Corresponding to a speculative extrapolation of 4 856 532 new cases for Sepsis-1 and 2 487 949 new cases for Sepsis-3, there were 831 674 deaths and 700 437 deaths per year in China, respectively. Conclusions Male, elder, more comorbidities and low BMI were risk factors for sepsis. The standardized incidence of Sepsis-3 in Yuetan Subdistrict of Beijing was 236 per 100 000 person-year, and speculated there were 2.5 million new cases of Sepsis-3 per year, resulting in more than 700 000 deaths in China. According to the diagnostic criterion of Sepsis-3, 2.36 million new cases per year were reduced, and the mortality was increased by 11.4%, as compared with the criterion of Sepsis-1.

Background and objective As computed tomography (CT) screening for lung cancer becomes more common in China, so too does detection of pulmonary ground-glass nodules (GGNs). Although anumber of national or international guidelines about pulmonary GGNs have been published,most of these guidelines are produced by respiratory, oncology or radiology physicians, who might not fully understand the progress of modern minimal invasive thoracic surgery, and these current guidelines may overlook or underestimate the value of thoracic surgery in the management of pulmonary GGNs. In addition, the management for pre-invasive adenocarcinoma is still controversial. Based onthe available literature and experience from Shanghai Pulmonary Hospital, we composed this consensus about diagnosis and treatment of pulmonary GGNs. For lesions which are considered as adenocarcinoma in situ, chest thin layer CT scan follow-up is recommended and resection can only be adopt in some specific cases and excision should not exceed single segment resection. For lesions which are considered as minimal invasive adenocarcinoma, limited pulmonary resection or lobectomy is recommended. For lesions which are considered as early stage invasive adenocarcinoma, pulmonary resection is recommend and optimal surgical methods depend on whether ground glass component exist, location, volume and number of the lesions and physical status of patients. Principle of management of multiple pulmonary nodules is that primary lesions should be handled with priority, with secondary lesions taking into account.
