Objective: To investigate the trends in mortality and life loss of gastric cancer in Wenzhou City, Zhejiang Province from 2014 to 2023, so as to provide the evidence for formulating the prevention and control strategy for gastric cancer. Methods: The surveillance on causes of death data of permanent residents in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management Information System from 2014 to 2023. The crude mortality of gastric cancer was calculated, and standardized by the data from the Sixth Chinese National Population Census in 2010. The life loss were measured using potential years of life lost (PYLL) and rate of potential years of life lost (PYLLR). The characteristics of mortality and life loss of gastric cancer in different genders and age groups were described. The trends in mortality and PYLLR of gastric cancer were analyzed using the average annual percent change (AAPC). Results: Totally 17 080 deaths were reported due to gastric cancer in Wenzhou City from 2014 to 2023, accounting for 12.58% and ranking third in the order of malignant tumor deaths. The crude mortality of gastric cancer was 20.73/105, and the standardized mortality was 15.22/105, showing decreasing trends (AAPC=-3.311%, -6.470%, both P<0.05). The crude mortality of gastric cancer was 29.22/105 in men and 11.61/105 in women, with standardized mortality rates of 20.81/105 and 8.74/105 (both P<0.05). The crude mortality of gastric cancer appeared a tendency towards a rise with increasing age (P<0.05), reaching the highest rate of 225.88/105 in the group aged 80 to <85 years. The PYLL and PYLLR of gastric cancer were 107 607.50 person-years and 1.37‰. The PYLLR appeared a tendency towards a decline from 2014 to 2023, with AAPC of -6.667% (P<0.05). Conclusions The mortality and PYLLR of gastric cancer in Wenzhou City appeared a tendency towards a decline from 2014 to 2023. Men and the elderly populations were the key groups for the prevention and treatment of gastric cancer.

Objective: To investigate the association between overweight, obesity, central obesity and hypertension, so as to provide the basis for formulating targeted hypertension prevention and control strategies. Methods: Permanent residents aged ≥18 years were selected in Wenzhou City, Zhejiang Province from June 2023 to August 2024 by a multistage cluster random sampling method. Data on demographic information, lifestyle, height, weight, waist circumference (WC), blood pressure, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. The prevalence of hypertension was calculated and standardized using the data of the Sixth National Population Census in 2010. Body mass index (BMI) was calculated to determine overweight and obesity, while WC was used to identify central obesity. The association between overweight, obesity, central obesity and hypertension were analyzed using multivariable logistic regression models. Results: A total of 38 593 residents were surveyed, including 19 481 (50.48%) males and 19 112 (49.52%) females. The median age was 46.00 (interquartile range, 26.00) years. The rates of overweight, obesity, and central obesity were 32.74% (12 634 individuals), 10.27% (3 963 individuals), and 27.87% (10 755 individuals), respectively. There were 11 813 cases of hypertension, with a prevalence and standardized prevalence of 30.61% and 24.41%, respectively. Multivariable logistic regression analysis showed that after adjusting for demographic information, lifestyle, diabetes and dyslipidemia, the likelihood of hypertension in the overweight and obesity groups was 1.927 (95%CI: 1.815-2.045) times and 3.724 (95%CI: 3.404-4.073) times that of the normal BMI group, respectively. The likelihood of hypertension in the central obesity group was 2.346 (95%CI: 2.214-2.486) times that of the normal WC group. The likelihood of hypertension in the central obesity only, overweight only, overweight with central obesity, obesity only and obesity with central obesity groups was 1.586 (95%CI: 1.391-1.809), 1.704 (95%CI: 1.582-1.835), 2.433 (95%CI: 2.254-2.626), 1.768 (95%CI: 1.424-2.194), and 4.466 (95%CI: 4.053-4.921) times that of the normal BMI and WC group, respectively. Conclusions Overweight, obesity and central obesity were all associated with hypertension among adult residents. The highest likelihood of hypertension was observed among adult residents with both general obesity and central obesity.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective: To investigate the mortality and life loss of female breast cancer in Wenzhou City, Zhejiang Province from 2014 to 2022, so as to provide the evidence for prevention and control of breast cancer. Methods: Data of female breast cancer deaths in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management information System from 2014 to 2012. The mortality of breast cancer was calculated, and standardized by the data from the Sixth Chinese National Population Census in 2010 (Chinese-standardized rate) and the world standard population first introduced by Segi (world-standardized rate). The life loss were measured using potential years of life lost (PYLL), rate of potential years of life lost (PYLLR) and average years of life lost (AYLL). The trends in mortality, PYLLR and AYLL were analyzed using the average annual percent change (AAPC). Results: Totally 2 523 deaths were reported due to breast cancer from 2014 to 2022, ranking fifth in the order of female malignant tumor deaths. The crude mortality of female breast cancer was 7.13/105, showing an increasing trend with AAPC of 2.186% (P<0.05). The Chinese population-standardized mortality and global population-standardized mortality were 5.93/105 and 4.39/105, showing no significant trend with AAPC of -0.617% and -0.602% (both P>0.05), respectively. The crude mortality of female breast cancer appeared a tendency towards a rise with age (P<0.05). The crude mortality of breast cancer in females aged 65 years and older showed an increasing trend (AAPC=3.283%, P<0.05), but there were no significant tendency aged 15 to <45 years and 45 to <65 years (AAPC=-1.011% and -1.850%, both P>0.05). The PYLL, PYLLR and AYLL of breast cancer were 41 227.50 person-years, 1.23‰ and 19.44 years per person, respectively. AYLL showed a decreasing trend (AAPC=-1.969%, P<0.05), and PYLLR showed no significant trend (AAPC=-0.527%, P>0.05). Conclusions The mortality of female breast cancer in Wenzhou City appeared a tendency towards a rise from 2014 to 2022, and AYLL appeared a downward trend. Females aged 65 years and older were the key groups for the prevention and control of breast cancer.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To evaluate the application value of the Global Leadership Initiative on Malnutri-tion(GLIM)criteria in the patients with gastric cancer radical surgery,and to explore the relationship be-tween the malnutrition defined by GLIM criteria and the prognosis of the patients with gastric cancer radical surgery.Methods A total of 150 gastric cancer patients receiving radical surgical resection in Zhejiang Provin-cial Tongde Hospital from January 2014 to December 2017 were selected as the study subjects.All the study subjects were diagnosed as malnutrition and graded by the severity of malnutrition.The effect of malnutrition defined by GLIM criteria on the prognosis of the patients with gastric cancer radical surgery was evaluated by the Kaplan Meier survival curve and Cox regression analysis.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of GLIM criteria on the postoperative survival rate of the pa-tients with gastric cancer radical surgery,and the corresponding area under the curve(AUC)was calculated,and the predictive value of inflammatory indicator C-reactive protein(CRP)addition on GLIM criteria in pre-dicting the prognosis of the patients with gastric cancer radical surgery was evaluated.Results Malnutrition diagnosed by GLIM criteria was an independent risk factor affecting the postoperative survival rate of the pa-tients with gastric cancer radical surgery.The results of survival trend analysis of various indicators in GLIM criteria showed that involuntary weight reduction(moderate malnutrition HR=14.13,95％CI:1.70-117.39,severe malnutrition HR=12.50,95％CI:1.40-111.89)and CRP＞10 mg/L(HR=9.70,95％CI:2.31-40.67)were the most important factors affecting the survival rate of the patients with gastric cancer radical surgery.In addition,the addition of inflammatory marker CRP could increase the sensitivity and speci-ficity of the GLIM model in predicting the postoperative survival rate of the patients with gastric cancer radical sur-gery.Conclusion The GLIM criteria can not only reflect the nutritional status of the patients with gastric cancer radi-cal surgery,but also serve as an effective predictive tool for predicting the survival rate after radical surgery.The addition of inflammatory marker CRP increases the sensitivity and specificity of GLIM criteria in predicting postoperative survival rate.

Objective To investigate the dynamic change of nutritional risk and malnutrition before op-eration and chemotherapy beginning and at the chemotherapy end in the patients with gastrointestinal malig-nant tumors.Methods The patients receiving gastrointestinal malignant tumors operation in Zhejiang Provin-cial Tongde Hospital from January 2017 to December 2022 were selected as the study subjects.The anthropo-metric measurement data,Karnofsky functional status(KPS)score change were recorded before operation and chemotherapy beginning and at the chemotherapeutic end.The nutritional risk screening 2002(NRS2002)and Global Leadership Initiative Consensus on Diagnostic Criteria for Malnutrition(GLIM)were adopted to evalu-ate the nutritional status of the patients.Results A total of 239 patients were included,there were 221 cases(92.47％)of nutritional risk before the chemotherapeutic beginning,206 cases(86.19％)of GLIM standard malnutrition,71 cases(29.70％)of moderate malnutrition and 135 cases(56.49％)of severe malnutrition in GLIM classification evaluation.At the chemotherapeutic end,there were 182 cases(76.15％)of nutritional risk,181 cases(73.75％)of GLIM standard malnutrition,52 cases(21.76％)of moderate malnutrition and 129 cases(53.97％)of severe malnutrition in GLIM classification evaluation.The screening rate of nutritional risk and malnutrition at the chemotherapeutic end were significant higher than those before operation and the difference was statistically significant(P＜0.001).The levels of total protein,albumin,leukocyte count,neu-trophile granulocyte,hemoglobin and platelet count at the chemotherapeutic end were decreased compared with those before operation with statistical difference(P＜0.05).Conclusion The nutritional risk and malnu-trition incidence rate in the patients with gastrointestinal malignant tumors are high,moreover which at the chemotherapeutic end are higher than those before operation.

Objective To explore the value of preoperative nutritional risk screening and malnutrition on postoperative prediction in the patients with gastrointestinal tract malignant tumor.Methods A total of 428 patients with gastrointestinal tract malignant tumors receiving elective operation in the gastrointestinal surgery department and proctology department of this hospital from January 2017 to October 2023 were se-lected as the study subjects.The patients were classified by postoperative complications Clavien-Dindo classifi-cation and divided into non-complication group(n=288)and complication group(n=140)according to whether or not having complications.The Nutritional Risk Screening 2002(NRS2002)and Global Leadership Initiative on Malnutrition(GLIM)were adopted to evaluate the nutritional status of the patients.The postop-erative complications during the hospitalization period,hospitalization duration,hospitalization expenses,30 d and 60 d non-planed readmission were recorded.Results Compared with the non-complication group,the age,complications ≥2,NRS2002 score ≥3 points,severe malnutrition proportion,urea level,hospitalization dura-tion,hospitalization expenses,ICU admission ratio,30 d and 60 d non-planned readmission rate in the compli-cation group were higher,BMI,KPS score,albumin,total calcium,low density lipoprotein,RBC count,Hb and HCT level were lower,and the differences were statistically significant(P＜0.05).The logistic regression a-nalysis results showed that after adjusting the relevant confounding factors,nutritional risk in NRS2002 screening,malnutrition in GLIM assessment and moderate to severe malnutrition in GLIM classification were all risk factors for postoperative complications occurrence in the patients with gastrointestinal malignant tumors(P＜0.05).None of them were the risk factors for unplanned readmission on 30,60 d(P＞0.05).The receiver operating characteristic(ROC)curve analysis results showed that the arae under the curve(AUC)of NRS2002 was greater than that of GLIM(0.733 vs.0.704),and the difference was statistically significant(P＜0.05).There was no statistically significant difference in the comparison among the GLIM grading(0.710)in NRS2002 and GLIM(P＞0.05).Conclusion The predictive ability of NRS2002 for postoperative complications in the patients with gastrointestinal tract maliganat tumors is slightly superior to that of GLIM.

The purpose of this study was to identify the tick species native to Xindi Township,Yumin County,Xinjiang,China.Preliminary morphological identification of parasitic ticks collected from animals in the area was conducted with an ultra-depth of field three-dimensional VHX 600 digital stereo microscope.Total DNA of the ticks was extracted,amplified by PCR based on the COI and ITS2 gene loci,and the posi-tive PCR products were sequenced.The sequence were a-ligned with reference sequences from the NCBI database were aligned with the Basic Local Alignment Search Tool.A genet-ic phylogenetic tree was generated with the neighbor-joining method of MEGA 7.0 software to determine the evolutionary biological characteristics of ticks.Morphological identification showed that the ticks collected from Xindi Township of Yu-min County were consistent with the characteristics of Hya-lomma asiaticum.An evolutionary tree based on the COI and ITS2 gene sequences showed that the ticks collected in this study were clustered with known H.asiaticum sequences.The PCR products of COI and ITS2 were sequenced and compared,which confirmed that the collected tick species were H.asiaticum,in agreement with the morphological and molecular biological results.These findings help to clarify the distribution of ticks in Xindi Township of Xinjiang,and provide basic data for the analysis of tick genetic and evolutionary characteristics,as reference for surveillance and control of ticks in the Xinjiang Uygur Autonomous Region.
