Precancerous lesions of gastric cancer is a key stage in the development of gastric cancer.The reprogramming of glucose metabolism is a prominent feature of precancerous lesions of gastric cancer.Hypoxic microenvironment and hypoxia-inducible factors are important factors influencing the occurrence of glucose metabolic reprogramming.This article summarized the relationship between hypoxic microenvironment and the reprogramming of glucose metabolism in precancerous lesions of gastric cancer,and concluded the relevant research on TCM compounds and effective components to improve hypoxic microenvironment and further regulate glycolysis for the treatment of this disease.It was concluded that the mechanism may be the inhibition of angiogenesis,regulation of signaling pathways and key proteins of glycolysis,expression of multiple enzymes,reduction of lactate secretion,inhibition of cell malignant proliferation and invasion.It explored the mechanism of Chinese materia medica in improving hypoxic microenvironment and regulating glycolysis,so as to provide reference for the prevention and treatment of precancerous lesions of gastric cancer.

Nonalcoholic fatty liver disease （NAFLD） is one of the most common complications of type 2 diabetes mellitus （T2DM）. Cell death caused by iron-lipid disorder is a new mode of regulating programmed cell death， which is characterized by lipid peroxidation induced by the accumulation of lipid reactive oxygen species and excessive accumulation of iron ions induced by iron metabolism disorders. Among them， iron homeostasis disorder and metabolic pathway disorder are the main causes of iron-lipid disorder， which play an important role in a variety of pathological processes related to cell death. Because the liver is an important organ for iron storage and lipid metabolism， iron-lipid disorder is an ideal target for liver disease， and inhibition of iron-lipid disorder may become a new strategy for the treatment of NAFLD. However， the pathogenic relationship and mechanism between NAFLD and iron-lipid disorder have not been fully elucidated. Based on the complex molecular regulation mechanism of iron-lipid disorder， by expounding the role of iron-lipid disorder in NAFLD and its related mechanism， this paper summarizes the research status of traditional Chinese medicine on the target treatment of NAFLD in recent years， so as to provide a new perspective and point out a new direction for the treatment of NAFLD in the future.

The angiogenic microenvironment is a new blood vessel with different molecular and functional characteristics that sprouts on the original blood vessels through different mechanisms,which directly affects the process of tumor cell growth,proliferation,and migration and has an important impact on the occurrence and development of precancerous lesions of gastric cancer.Correa mode has shown that precancerous lesions of gastric cancer is the key pathological stage before the occurrence of gastric cancer,and it is of great significance to advance the prevention and treatment strategy to this stage.TCM believes that qi deficiency and blood stasis is the key pathogenesis of precancerous lesions of gastric cancer,and its basic treatment is to replenish qi and remove blood stasis,and based on the syndrome differentiation,drugs with the efficacy of nourishing yin and tonifying stomach,soothing the liver and regulating qi,resolving phlegm and dispersing lumps,and clearing heat and dampness for treatment.This article discussed the correlation between precancerous lesions of gastric cancer and angiogenic microenvironment and its regulatory pathways,and summarized the methods and mechanisms of TCM in the treatment of precancerous lesions of gastric cancer from the perspective of regulating angiogenic microenvironment-related pathways,in order to provide a reference for the treatment of precancerous lesions of gastric cancer with TCM.

Objective To discuss the evaluation basis of the clinical rational use of Dahuang Zhechong Capsule and to establish its rationality evaluation criterion to promote the sensible use of Dahuang Zhechong Capsule.Methods The rationality evaluation criterion for Dahuang Zhechong Capsule was formulated by referring to the package insert,treatment guidelines,and other literature.According to the criterion,270 outpatient prescriptions using Dahuang Zhechong Capsule in Xiyuan Hospital,China Academy of Chinese Medical Sciences were reviewed from January to June 2020.The indication,usage and dosage,drug combination,and repeated administration were analyzed.The pharmaceutical intervention was performed to address the problems found in the prescription reviews,and 328 outpatient prescriptions using Dahuang Zhechong Capsule in October 2020 were reevaluated.Results The irrational use rate of Dahuang Zhechong Capsule from January to June 2020 was 42.22％(114 cases),including 108(40％)cases of inappropriate indications,five(1.85％)cases of improper usage and dosage,and one(0.37％)case of inappropriate administration route.However,the pharmaceutical intervention in October 2020 remarkably reduced the irrational use rate of Dahuang Zhechong Capsule(4.27％,14 cases),all of which were inappropriate indications.Conclusion Dahuang Zhechong Capsule is being used irrationally;therefore,establishing an evaluation criterion is required.The specific situation of irrational drug use can be identified by prescription review according to its rationality evaluation criterion to manage its clinical use better and promote its rational use.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

To investigate the effect of Zhiwei Fuwei Pills (ZWFW) on the expression of mammalian target of rapamycin (mTOR)/autophagy key molecule yeast Atg6 homologue (Beclin1)/microtubuleassociated protein 1 light chain 3 (LC3) signaling axis key molecules in gastric antrum tissue of rats with precancerous gastric lesions (PLGC). METHODS: SPF SD rats were randomly divided into normal group, model group, folic acid group, ZWFW low-dose, medium-dose, high-dose group. In addition to the normal group, the model group, folic acid group, ZWFW low-dose, medium-dose and high-dose groups, were used to establish the PLGC rat model by five factors compound modeling methods: N-methyl-N ' - nitro-n-nitroguanidine (MNNG) combined with hunger and satiation, ethanol intragastric administration, free drinking of ammonia and ranitidine feed. The rats were treated with normal saline, folic acid tablet aqueous solution (0.002 g/kg), ZWFW low-dose, medium-dose, high-dose aqueous solution (0.42, 0.84, 1.67 g/kg) for 4 weeks, and the stomach was removed by laparotomy. Hematoxylineosin (HE) staining was used to observe the histopathological changes in the antrum of rats, and real-time polymerase chain reaction (real-time PCR), Western blot (WB) and immunohistochemistry (IHC) were used to detect the expression of mammalian target of rapamycin mTOR, yeast Atg6 homologue 1 (Beclin1), microtubule-associated protein 1 light chain 3β (LC3B) mRNA and protein in the antrum of rats. RESULTS: Compared with the normal group, the Gastric antrum tissue of the model group was distended, thinner gastric wall, palegastric mucosa, atrophic and flat folds, disordered course and nodules and vegetations were visible. HE staining showed that compared with the normal group, the gastric mucosal glands in the model group were crowded and disordered, and the cell morphology was different, including a large number of goblet cells, basophilic cytoplasm, large, hyper-chromatic and irregular nuclei, and mucosal muscle infiltration and destruction. Compared with the model group, treated by ZWFW can significantly improve the pathological manifestations of gastric mucosal gland structure disorder and cell atypia. Compared with the normal group, mTOR mRNA and protein expression were significantly increased (P< 0.05) and Beclin1 and LC3B mRNA and protein expression were significantly decreased (P<0.05) in the antral tissue of rats in the model group; compared with the model group, mTOR mRNA and protein expression were decreased (P<0.05) in the medium and high dose groups of ZWFW, Beclin1 and LC3B protein expression in the antral tissue of rats in the low dose group of ZWFW and Beclin1 and LC3B mRNA and protein expression were increased (P<0.05) in the medium and high dose groups. CONCLUSION: Zhiwei Fuwei Pills can significantly improve the abnormal histopathological findings of gastric mucosa in PLGC model rats, and the mechanism may be related to the down-regulation of mTOR expression, up-regulation of Beclin1 and LC3B expression and then promoting autophagy.

Objective:To provide strategical reference for large-scale colorectal cancer screening with full regional coverage by analyzing the results of the first colorectal cancer screening in the target population in Linhai city,Zhejiang Province. Methods:The target population of 50-74 years old in Linhai were invited to take part in the colorectal cancer screening program from 2020 to 2021.The risk of colorectal cancer of the participants were preliminarily evaluated by questionnaire and qualitative fecal occult blood test(FOBT),and participants with positive screening results were suggested to take colonoscopy test for further evaluation.The screening results were collected and analyzed. Results:A total of 71 942 people were screened from 2020 to 2021,and 15 1 70 of them were found positive in preliminary screening.The positive rate in males was significantly higher than that in females(x 2=724.005,P＜0.001),and the positive rate was highest in the population of 60-69 years old during preliminary screening.The compliance rate of colonoscopy was 24.1 9％with no significant difference between males and females(x 2=0.256,P=0.61 3),showing a decreasing trend as the age increases.From 2020 to 2021,the detection rate of lesions by colonoscopy was 52.92％,with 47 case of colorectal cancer(CRC),333 case of advanced colorectal adenoma,561 case of non-advanced colorectal adenoma and 1 001 case of benign lesions.The detection rate of lesions in males was much higher than that in females(x 2=82.451,P＜0.001).The detection rates of lesions,advanced colorectal adenoma,and non-advanced adenoma showed increasing trends with the age.The compliance rate of colonoscopy,the detection rate of lesions,and the detection rate of CRC,advanced colorectal adenoma,and non-advanced adenoma were 32.94％,69.53％,2.87％,1 6.85％and 1 9.71％,respectively,in participants who were both assessed as high-risk according to questionnaire evaluation and FOBT positive,the highest among all participants.The compliance rate of colonoscopy in 2021 was obviously higher than that in 2020(32.11％vs 1 9.09％,P＜0.001),but no significant difference was found in the detection rate of lesions between 2021 and 2020(P＞0.05). Conclusion:From 2020 to 2021,the compliance rate of colonoscopy was low and the detection rate of colorectal lesions was high during the screening of colorectal cancer in the target population in Linhai,Zhejiang Province.It is necessary to enhance the public awareness of the importance of colorectal cancer screening,standardize the enrollment criteria,and improve the compliance of colonoscopy,in orderto give full play to primary screening in the general public.

Gastric cancer is one of the most common malignant tumors of the digestive system， with a high incidence， a low overall survival rate， and poor prognosis after treatment. It has become a major public health problem that threatens the lives and health of people. Since the pathogenesis of gastric cancer is still not fully unraveled， it is difficult to implement primary prevention. Therefore， the research on secondary prevention of gastric cancer， i.e.， precancerous lesions of gastric cancer， is extremely important and has become the focus of many researchers. Precancerous lesions of gastric cancer are the key pathological links in the transformation of inflammatory lesions of gastric mucosa into gastric cancer， including chronic atrophic gastritis， intestinal metaplasia， and dysplasia. Relevant studies have confirmed that with the aggravation of gastric mucosal lesions， the incidence and risk of gastric cancer also increase. Therefore， early diagnosis and effective intervention in the pathological link of gastric precancerous lesions is a key measure to prevent and reduce the incidence of gastric cancer， with great significance. More studies have shown that traditional Chinese medicine （TCM） can truncate and reverse the pathological grading of gastric mucosa， and can also effectively improve the clinical symptoms and quality of life of patients， with few adverse reactions and low recurrence rate， which has unique advantages and characteristics. The theory of ''pathogen invading nutrient and blood aspects'' was first proposed by WU Youxing， a febrile disease doctor， in Treatise on Pestilence （《温疫论》）. It was originally used for the treatment of syndrome changes in the late stage of febrile epidemics， but after being enriched and developed by different doctors， it is now mostly used to guide the treatment of various chronic diseases. Precancerous lesions of gastric cancer are a common and difficult disease in clinical practice. Its evolution process is characterized by asthenia in origin and sthenia in superficiality and deficiency-excess in complexity， which is consistent with the core pathogenesis of ''pathogen invading nutrient and blood aspects''， namely， positive deficiency and intruding pathogen， and intruding pathogen cementation in the blood vessels. They are also interlinked in terms of treatment principles. Therefore， with the theory of ''pathogen invading nutrient and blood aspects'' as the breakthrough point， this article expounded the intervention effect of TCM on precancerous lesions of gastric cancer from the perspective of this theory， reflecting its important guidance and application value and providing new ideas for clinical treatment of diseases.

Objective:To analyze common respiratory pathogens epidemiology in hospitalized children with lower respiratory tract infection (LRTI) in a single center in Shanghai, and to provide the basic data support for clinical diagnosis and treatment of children with LRTI in Shanghai.Methods:Children with LRTI in Children′s Hospital of Fudan University were enrolled from January 1, 2015 to December 31, 2019, and respiratory samples were collected and tested by direct immunofluorescence assay and real time polymerase chain reaction. The epidemiological characteristics of different respiratory pathogens were analyzed. Chi-square test was used for statistical analysis.Results:A total of 18 716 children were included, the total detection rate of respiratory pathogens was 36.96% (6 918/18 716), and the most frequent detected pathogen was Mycoplasma pneumoniae (MP) (15.31%(2 866/18 716)), followed by respiratory syncytial virus (RSV) (10.40%(1 946/18 716)) and parainfluenza virus Ⅲ (PIV-Ⅲ) (4.65%(871/18 716)). The detection rate of pathogens in female was significantly higher than that in male (38.48%(2 936/7 630) vs 35.92%(3 982/11 086), χ2=12.72, P<0.001). RSV and influenza virus A (Flu-A) infections peaked in winter. The detection rates of influenza virus B (Flu-B) and human metapneumovirus (MPV) were higher in winter and spring. PIV-Ⅲ infection peaked in spring and summer. The peak of PIV-Ⅱ infection occurred in summer and autumn. The infections of adenovirus (ADV), MP, Chlamydia trachomatis (CT) and PIV-Ⅰ were prevalent throughout the year without significant seasonality. The detection rate of RSV declined with age, while the detection rate of MP increased with age. The co-infection rate was 1.65%(309/18 716), and the predominant co-infection type was MP and RSV (0.37%(70/18 716)). Conclusions:A variety of pathogens lead to children′s LRTI in Shanghai from 2015 to 2019, with the common infection of MP, RSV and PIV-Ⅲ. Different pathogens showed different epidemiological characteristics in age and season distributions.

Objective:To analyze the influences of leukocytes on improving blood glucose control in patients with type 2 diabetes mellitus (T2DM) and periodontitis after periodontal mechanical therapy.Methods:Thirty-five patients visiting Peking University Third Hospital from March 2011 to August 2012, as well as thirty-four patients visiting Peking University School and Hospital of Stomatology from March 2011 to August 2012 and December 2016 to December 2018 were selected in this research. These subjects were non-smokers, and with moderate to severe chronic periodontitis and T2DM. The full set of periodontal examinations including probing depth (PD), attachment loss (AL), bleeding index (BI) and plaque index (PLI) were conducted. Besides, counts of white blood cells (WBC), parameters of glucose and lipids metabolites such as fasting blood glucose (FBG), glycosylated hemoglobin (HbA 1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) in serum were examined before treatment. Then, oral hygiene instruction, scaling and root planing (SRP) were carried out. Three months after SRP, the baseline examinations were repeated in all patients. According to the baseline leukocyte counts, the patients were divided into subgroups: low WBC group (WBC<6.19×10 9/L) and high WBC group (WBC≥6.19×10 9/L). Paired t-test for comparison of changes after treatment, analysis of co-variance for comparing the intervention effects between subgroups, and multifactor Logistic regression analysis were performed. Results:Three months after SRP, all periodontal indexes were significantly improved in both groups. Leukocyte counts decreased significantly in high WBC group (6.89±1.53 vs. 7.64±1.51, P=0.008). In high WBC group, HbA 1c (7.18±1.09 vs. 7.67±1.35, P=0.001) and LDL (2.67±0.85 vs. 3.28±0.76, P=0.042) decreased significantly, while there were no such differences in low WBC group. Influence of leukocyte level on HbA 1c ( OR=0.12, P=0.038) and LDL ( OR=0.15, P=0.001) improvement was statistically significant. Hierarchical analysis showed such improvement notably perform in female [HbA 1c ( OR=0.30, P=0.021), LDL ( OR=0.34, P=0.001)] and severe periodontitis group [HbA 1c ( OR=0.15, P=0.025), LDL ( OR=0.24, P=0.017)]. Through interaction test, female and leukocyte counts at baseline had relative excess risk affecting the effect of periodontal intervention on HbA 1c ( P=0.036) and LDL ( P=0.005). Conclusions:SRP could significantly improve the blood glucose and lipid control in patients who had T2DM and chronic periodontitis with relative higher leukocytes level. Female patients with severe periodontitis showed more obviously effects.
