ABSTRACT
OBJECTIVE To evaluate the cost-effectiveness of sintilimab combined with chemotherapy than single-use chemotherapy in the first-line treatment of advanced， recurrent or metastatic esophageal squamous cell carcinoma （ESCC） from the perspective of health system of our country， and provide reference for rational use of drug in clinic. METHODS Based on ORIENT-15 study data， TreeAge Pro 2011 software was used to establish a three-state Markov model of non-progressive survival （PFS）， disease progression and death for cost-utility analysis. The model period was 3 weeks， the research time limit was 10 years， and the discount rate was 5%. The main outputs of the model were total cost， quality-adjusted life year （QALY） and incremental cost-effectiveness ratio （ICER）. The 1-3 times of China’s GDP per capita in 2021 was taken as the threshold of willing- ness to pay （WTP）. The uncertainty of the parameters was analyzed by single factor sensitivity analysis and probability sensitivity analysis， and the cost-effectiveness of the two schemes was discussed under three situations： different discount rates， comparison with other similar treatment schemes and charitable drug donation schemes. RESULTS The results of basic analysis showed that compared with chemotherapy plan alone， the ICER of sintilimab combined with chemotherapy was 64 208.75 yuan/QALY， which was less than WTP threshold. The results of single factor sensitivity analysis show that PFS state utility value， cycle cost of sintilimab and discount rate had relatively great influence on the results. Probability sensitivity analysis showed that when WTP≥120 000 yuan， the economic probability of sintilimab combined with chemotherapy plan was 100%. The results of situational analysis showed that sintilimab combined chemotherapy was more cost- effective than single-use chemotherapy. CONCLUSIONS Sintilimab combined with chemotherapy is more cost-effective than single-use chemotherapy in the first-line treatment of advanced， recurrent or metastatic ESCC.
ABSTRACT
ObjectiveTo evaluate the efficacy and influencing factors of Biejiajianwan in the treatment of primary liver cancer based on real-world data of traditional Chinese medicine （TCM）. MethodClinical diagnosis and treatment data of patients with primary liver cancer admitted to five Grade-A tertiary hospitals in Henan Province from January 2015 to December 2020 were collected from the medical electronic database. The patients treated with Biejiajianwan for ≥30 days were assigned to the exposure group and those without treatment with Biejiajianwan or treated with Biejiajianwan for <30 days to the non-exposure group. The propensity score matching model was used to balance confounding factors between the two groups according to the 1∶1 genetic matching method. Kaplan-Meier method was used for survival analysis and survival curve plotting. Log-rank was used to test the difference in survival rate between the two groups. Univariate analysis of Biejiajianwan in the treatment of primary liver cancer was performed by Log-rank test combined with the Kaplan-Meier method. The factors with statistical significance （P<0.05） were combined with unbalanced factors by the propensity score matching model， and at the same time， clinical common sense and relevant prognostic factors by literature search were considered， which were subjected to multivariate analysis by Cox proportional hazards regression model. ResultA total of 2 207 electronic cases were collected，including 174 cases in the exposure group （Biejiajianwan group） and 2 033 cases in the non-exposure group. After propensity score matching， there were 174 cases in the exposure group and 174 cases in the non-exposure group. The Kaplan-Meier method was used for survival analysis on the matched data， and the Log-rank test results showed that the survival rate of patients with primary liver cancer in the Biejiajianwan group was higher than that in the control group （χ2=12.193， P<0.01）. Cox proportional hazards regression model analysis showed that the regression coefficient of Biejiajianwan was -0.916 4 with the hazard ratio （HR） ［95% confidence interval （CI）］=0.4 （0.239 5-0.668 0）， P<0.01， and the regression coefficient of radiofrequency ablation treatment was -0.976 5 with HR （95% CI）=0.376 6 （0.172 8-0.821 1， P<0.05）. Fibrinogen （FIB） abnormal regression coefficient was 0.481 4 with HR （95% CI）=1.618 4（1.022 0-2.562 9），P<0.05. ConclusionBiejiajianwan can prolong the survival period of patients with primary liver cancer. Radiofrequency ablation is an independent protective factor for Biejiajianwan in the treatment of primary liver cancer，while abnormal FIB are independent risk factors for Biejiajianwan in the treatment of primary liver cancer.

Objective To establish a prediction model for tuberculosis incidence in Nantong area by multivariate regression analysis, and to provide theoretical support for the implementation of combined prevention work in this area. Methods A total of 37 338 registered patients with pulmonary tuberculosis in Nantong City from 2010 to 2021 were enrolled in the observation group. A total of 28,721 healthy people who underwent physical examination during the same period were selected as the control group. Results From 2010 to 2021, there were a total of 37 338 cases of pulmonary tuberculosis in central Nantong. From 2010 to 2015, more than 3,000 cases were reported annually, with the largest number (4 142 cases) in 2011, accounting for 11.09% of the total. The number of cases reported from 2016 to 2021 was all less than 3 000, and the number of cases reported from 2021 was the least , 1 803 cases, accounting for 4.83% of the total. The number of cases decreased each year in the past 12 years. The incidence of pulmonary tuberculosis in males was 70.97% (26 497 cases) and that in females was 29.03% (10 841 cases). In terms of age, the lowest incidence rate was 0.06% (23 cases) in the age group of 0-9 years old, and the highest incidence rate was 19.56% (7 304 cases) in the age group of 60-69 years old. Logistics regression analysis showed that male, age ≥60 years old, occupation as a farmer and smoking history were the risk factors for pulmonary tuberculosis (P < 0.05). ROC curve results showed that the AUC value of the risk prediction model for pulmonary tuberculosis in the Nantong area was 0.872, with a predictive sensitivity of 86.32% and a specificity of 89.21%. Conclusion There are many risk factors for pulmonary tuberculosis in Nantong area, and different factors interact and influence each other. The construction of a risk prediction model for pulmonary tuberculosis can better predict the clinical incidence, which is helpful to guide clinical diagnosis and treatment.
ABSTRACT
An 85-year-old woman with gross hematuria for 10 days was presented to Wuxi No.2 People′s Hospital on Dec 10th, 2018.The images showed bladder mass. Pathological analysis of transurethrally resected tissue showed primary malignant melanoma with less pigmentations of urinary bladder. Without any following treatment, it grew again after 17 months. After the second surgery, she died of cachexia half a month later. Primary malignant melanoma with less pigmentations of urinary bladder is rare. It is vulnerable to misdiagnosis without immunohistochemical staining. The prognosis is poor.

ABSTRACT
【Objective】 To investigate the status of blood donation of pregnant women's family members, so as to recruit their family members and establish potential blood donation team. 【Methods】 Questionnaire survey was carried out among family members of pregnant women who participated in blood preparation plan by random sampling. 【Results】 The motivations of self-efficacy, internal reward, severity and stress of blood donors were significantly higher than those of non-donors, but non-donors concerned more about negative feelings of phlebotomy(P<0.05). People with rare blood type, low age, high income, weak negative motivation and strong positive motivation had stronger blood donation intention and higher probability of blood donation behavior(P<0.05). 【Conclusion】 It is necessary to expand blood sources through multiple channels by organizing publicity activities around targeted groups, such as establishing channels for blood donation reservation, taking the lead role of the donated crowd, so as to build up a recruitment team for voluntary blood donation.
ABSTRACT
A 77-years-old female patient presented gross hematuria for one week, and CT showed a mass in the left kidney. Ureteroscopy detected a left renal mass. Laparoscopic nephroureterectomy was performed and pathology showed the tumor was mainly located in the renal parenchyma, with glomeruli around the tumor cells. Urothelium showed no obvious dysplasia or clear migration of tumor cells. Considering both the clinical symptoms, and squamous cell carcinoma not detecting in other locations of the patient, primary renal parenchyma was confirmed. Three months after surgery, CT detected recurrence in the operating area, with metastasis to the adjacent abdominal cavity and aorta lymph node.
ABSTRACT
Chlamydia, a gram-negative obligate intracellular pathogen, is a major cause of human reproductive tract, eye and respiratory tract infections. It replicates in a special membrane-binding chamber called inclusion and survives in the host′s hostile intracellular environment through secreting effectors, but requires host-derived lipids to grow and develop in the cells. Emerging evidences suggest that Chlamydia has evolved a variety of strategies to meet its lipid needs by interacting with host cell compartments and redirecting the transport pathway to its intracellular niche. This paper briefly described the pathway for obtaining host lipids and the mechanism of lipid metabolic during Chlamydia infection.
ABSTRACT
Attention is an essential cognitive function which was use to perceive the external world, and it is the basis of all cognitive activities.Other cognitive functions such as working memory, executive function, information processing speed and so on, are also adversely affected in hypoprosexia or hyperfocusing state.Patients with schizophrenia have severe attention disorder, which makes patients unable to successfully complete the task of work or study, thus reduce the quality of life.Attention disorder exists throughout the whole course of this disease, and there is no specific drug for it.In recent years, antipsychotic medications have widespread application, but it has not shown up significantly improvement of attention disorder, worse still, its side effects will exacerbate the disease, which results in the impairment of the patients' ability to learn and explore the novelties.Neuroimaging markers of attention disorder in schizophrenia are the focus of current researches.White matter fibers are important pathways that connect attention networks and maintain the three-dimensional structure of the brain.Previous studies have suggested that attention disorder may be related to abnormalities of white matter fibers connecting various encephalic regions.In particular, abnormalities in the integrity of white matter, such as corpus callosum, cingulum bundle, superior longitudinal fasciculus, inferior fronto-occipital fasciculus, have been reported to be significantly associated with attention disorder in patients with schizophrenia.In this study, the relationship between attention disorder and white matter structure in patients with schizophrenia is reviewed through diffusion tensor imaging (DTI) technique.
ABSTRACT
Objective@#Resting state functional magnetic resonance imaging (rsfMRI) provides a lot of evidence for local abnormal brain activity in schizophrenia, but the results are not consistent. Our aim is to find out the consistent abnormal brain regions of the patients with schizophrenia by using regional homogeneity (ReHo), and indirectly understand the degree of brain damage of the patients with drug-naive first episode schizophrenia (Dn-FES) and chronic schizophrenia. @*Methods@#We performed the experiment by activation likelihood estimation (ALE) software to analysis the differences between people with schizophrenia group (all schizophrenia group and chronic schizophrenia group) and healthy controls. @*Results@#Thirteen functional imaging studies were included in quantitative meta-analysis. All schizophrenia group showed decreased ReHo in bilateral precentral gyrus (PreCG) and left middle occipital gyrus (MOG), and increased ReHo in bilateral superior frontal gyrus (SFG) and right insula. Chronic schizophrenia group showed decreased ReHo in bilateral MOG, right fusiform gyrus, left PreCG, left cerebellum, right precuneus, left medial frontal gyrus and left anterior cingulate cortex (ACC). No significant increased brain areas were found in patients with chronic schizophrenia. @*Conclusion@#Our findings suggest that patients with chronic schizophrenia have more extensive brain damage than FES, which may contribute to our understanding of the progressive pathophysiology of schizophrenia.

ABSTRACT
【Objective】 To explore the feasibility and necessity of establishing a scheduled blood donation team focusing on pregnant women′s blood preparation by the comparative analysis between RhD positive and negative pregnant women′s family participation in the team, so as to provide basis for decision-making on fine management of key groups of voluntary blood donation. 【Methods】 A questionnaire survey was conducted between the families of RhD negative and positive pregnant women participating in the blood preparation program from January to September 2020 to compare the differences in incentive measures, blood donation cognition, motivation, intention and behavior between the two groups. 【Results】 For common incentive measures for blood donation, both families of RhD negative pregnant women(the former) and families of RhD positive pregnant women(the latter) preferred expectant mothers to use blood first, accounting for 98.02% (99/101) and 98.51% (132/134), respectively, with no significant difference.For other incentive measures, the preference of the former were significantly higher (P<0.05). For the cognition of voluntary blood donation, the awareness of the former was higher than that of the latter, with significant difference(P<0.05), except for clinical blood use expenses; the score of intention to donate blood of the former was higher than that of the latter(P<0.05); among the six factors of motivation to blood donation, the score of severity of the former(understanding of the status of blood supply) was higher than that of the latter, and the difference was statistically significant(P<0.05). Analysis of ROC curve showed that AUC of fitting model of the former and latter was 0.816 (95% CI: 0.731~0.902) and 0.924 (95% CI: 0.871~0.977). 【Conclusion】 Pregnant women families participated in the program are more interested in the incentive measures of health policies.The former has higher awareness of the current supply situation hence demonstrates higher intention to donate blood than the latter.Therefore, relevant policies should be formulated to improve the enthusiasm of pregnant women families to participate in voluntary blood donation, optimize the construction strategy of scheduled blood donation team and expand the donation team while ensuring blood use of pregnant women.
ABSTRACT
The mucosal surfaces of the human body are typically colonized by polymicrobial communities, they exist in the gastrointestinal tract, skin, oral cavity, and genitourinary tract, as well as in anatomical sites previously considered sterile, including the lung. These communities interact with the mucosal immune system to maintain homeostasis in health, emphasizing the important role of " second genome" , which is very important to human health. The human lower respiratory tract also harbor many microbes, the imbalance of microbiome composition maybe critically related with many lung disease. Up to date, researches on microbiome of lung caner is still on the first step. Our review mainly describes the characteristic composition of lung microbiome, and the relationship with diseases, especially with lung cancer. We attempts to provide the basis information for further researches about the relationship between human lung microbiome and lung cancer.

ABSTRACT
OBJECTIVE：To optimi ze the ratio of four comp onents of Compound renshen jianti formulation （Panax ginseng ， Dioscorea oppositifolia ，Lycium barbarum fruit，Alpinia oxyphylla ），and to investigate its anti-fatigue activity and acute toxicity. METHODS：The water extract of Compound renshen jianti formulation was prepared by water extraction ，concentration and decompression drying. By single factor tests ，using weight-bearing swimming time as index ，the effects of four factors were investigated，such as the amount of P. ginseng ，D. oppositifolia ，L. barbarum fruit，A. oxyphylla . On the basis of single factor tests，using comprehensive score of weight-bearing swimming time ，serum urea nitrogen content ，liver glycogen content and AUC of blood lactate after exercise as index ，the formulation was optimized by Box-Behnken response surface method. The mice was divided into blank control group （water），positive control group （Renshen hongjingtian capsules ，0.135 g/kg）and compound low-dose，medium-dose and high-dose groups [the optimal ratio of Compound renshen jianti formulation extract （called“optimal compound formulation ”for short ）4.08，8.16，12.24 g/kg，by crude drug] ，intragastric administration of drug or distilled water 20 mL/kg，once a day ，for consecutive 30 d. The weight-bearing swimming time ，the contents of serum urea nitrogen ，liver glycogen and blood lactate AUC after exercise were used to optimize its anti-fatigue activity of optimal compound formulation. The comprehensive score was calculated based on the measured data of mice in the compound formulation middle-dose group ， and the difference between it and the theoretical prediction value was compared. The mice were given optimal compound formulation intragastrically （total dose 16.00 g/kg， by extract）. The general state ， body mass change ， toxic characteristics and death of mice were observed and recorded for 14 days. Median lethal dose （LD50）and maximum tolerated dose （MTD）were measured. RESULTS ：The optimal formulation ratio of Compound renshen jianti formulation included that P. ginseng 1.5 g，D. oppositifolia 10 g，L. barbarum fruit 10 g，A. oxyphylla 3 g. Results of anti-fatigue activity validation test showed that the optimal compound formulation could significantly prolonged weight-bearing swimming time ，reduced serum content of urea nitrogen ，blood lactate content and its AUC （except for low-dose group ），while significantly increased the content of liver glycogen （P＜0.05 or P＜0.01）. Average comprehensive score of medium-dose group was 96.95，which was only 0.06％ different from the theoretical prediction value of 97.01. The results of acute toxicity test showed that there was no death in mice. The oral MTD of the optimal compound formulation was more than 15 g/kg，which was non-toxic. CONCLUSIONS ：The optimal Compound renshen jianti formulation has effective anti-fatigue activity of mice ，and has no significant toxic effect.

ABSTRACT
Objective:To compare CT with MRI on the accuracy in TNM staging of pancreatic ductal adenocarcinoma (PDAC) based on the 8th American Joint Committee on Cancer System and Pathological Staging.Methods:From October 2013 to October 2019, 105 patients who had pathologically confirmed PDAC treated at the Affiliated Wuxi No.2 People’s Hospital of Nanjing Medical University were retrospectively studied. Of 52 patients who met the inclusion criteria, there were 32 males and 20 females, with age ranging from 45 to 84 years (mean 66.1 years). Based on the 8th American Joint Committee on Cancer System and Pathological Staging, CT was compared with MRI in their accuracies in categorizing TNM and staging of PDAC.Results:Forty-three of 52 patients who underwent curative resection had a mean tumor size of (3.4±1.2) cm, compared with tumor sizes of (3.3±1.2) cm and (3.3±1.4) cm on CT and MRI, respectively. No significant differences were observed between gross pathological examination and CT ( P>0.05) or MRI ( P>0.05). The accuracy of T, N, and M categories on CT versus (vs) MRI was 97.7% (42/43) vs 97.7% (42/43), 79.1% (34/43) vs 76.7% (33/43), and 100% (9/9) vs 88.9% (8/9), respectively. No significant differences were observed between the two modalities ( P>0.05). The overall accuracy of PDAC staging on CT vs MRI was 82.7% (43/52) vs 76.9% (40/52), respectively. There was also no significant difference between the two modalities ( P>0.05). Conclusion:Both CT and MRI had similar accuracies in categorizing TNM and staging of PDAC. However, the accuracies of T and M stages were higher than that of the N stage for these two imaging modalities.
ABSTRACT
OBJECTIVE： To provide reference for standardization and improvement of teaching model for endocrinology speciality in community clinical pharmacists training base. METHODS： Based on the requirments of community clinical pharmacists training in Shanghai， the characteristics and contents of community clinical pharmacists training were summarized， and teaching characteriatiostics， effect evaluation and problems werer analyzed on the basis of the acutual situation in our hospital. RESULTS & CONCLUSIONS： Community clinical pharmacists training has the characteristics of training for chronic diseases， short training cycle， and support from the medical consortium platform. Its contents are theoretical learning and professional knowledge training， pharmaceutical care and medication education， case discussion， homework guidance and comment. Compared with other specility， endocrinology speciality has the characteristics of strengthening comprehensive pharmaceutical care （for example， pharmaceutical care of diabetic patients should pay attention not only to hypoglycemia， but also to hypobaric， hypolipidemic and complications）， emphasizing medication treatment management （MTM） teaching （provide a series of professional services such as medication education， counseling and guidance， and medical reorganization for patients， so as to improve the safety， effectiveness and compliance of medication， and then control blood glucose， delay or avoid complications）， emphasizing the cultivation of health education ability and communication ability. The evaluation of training effect included the evaluation of trainees and teachers. The former includes objective evaluation （theoretical knowledge test， bedside medication education assessment and homework assessment） and subjective evaluation （attendance， attitude， clinical practice performance）. The latter is mainly scored by trainees on teachers （including professional level， teaching attitude， teaching ability and content）. Through the training， it is found that the trainees’ literature retrieval ability is poor， the trainees have not clear idea to diabetic patients， the homework writing and typesetting are not standardized； the teaching teachers have less experience and teachers could not teach the students in accordance with their aptitude and provide individualized training. The training and teaching mode needed to be further improved.
