ObjectiveTo explore the law of women reproductive aging based on theory of "seven-year period" in traditional Chinese medicine（TCM） through analyzing the characteristics of basic sex hormone levels and anti-müllerian hormone levels in women of different ages. MethodsThe data of female who visited Guangdong Provincial Hospital of Traditional Chinese Medicine from January 2018 to December 2022 and accepted basic hormone and anti-müllerian hormone determination were collected retrospectively. According to the age of subjects， they were divided into the "1-2 seven" group （under 21 years old）， "3 seven" group （21-27 years old）， "4 seven" group （28-34 years old）， "5 seven" group （35-41 years old）， "6 seven" group （42-48 years old） and "7 seven" and older group （49 years old and above）. The age， average menstrual cycle in the past 3 months， basic hormone levels including follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， testosterone （T） and FSH/LH value， and anti-müllerian hormone （AMH） levels were collected and compared. ResultsA total of 1221 cases were included. The differences in FSH， LH， FSH/LH values， E₂， T， AMH levels and average menstrual cycle among the groups were statistically significant （P＜0.05 or P＜0.01）. AMH peaked in the "3 seven" group. Compared to those in the "3 seven" group， the FSH/LH value in the "4 seven" group increased， while the LH， AMH and T levels decreased， and the menstrual cycle was shortened （P＜0.01）. The FSH/LH， LH， AMH， T and menstrual cycle in the "5 seven" group were consistent with the changing trend of those in the "4 seven" group， while the FSH and E₂ levels in the "5 seven" group were significantly higher （P＜0.05 or P＜0.01）. Compared to those in the "5 seven" group， the FSH， LH and E₂ levels of the "6 seven" group increased， and the AMH and T levels continued to decrease （P＜0.05 or P＜0.01）. Compared to those in the "6 seven" group， the FSH and LH levels of the "7 seven" and older group continued to increase， and the AMH and E₂ levels decreased （P＜0.01）. ConclusionThe law of women reproductive aging in the "seven-year period" theory is basically consistent with the characteristics of basic sex hormone levels and anti-müllerian hormone levels in women of different ages. The reproductive capacity reaches its peak in the "three-seven-year period" and gradually moves towards reproductive aging in the "four-seven-year period".

Objective To explore the influence of organizational support on the career satisfaction of doctors in public hospitals and the mediating effect of role stress.Methods Using the survey data of 523 public hospital doctors from 9 medical institutions in 4 places in 2022,OLS linear regression model was used to analyze the influence of organizational support on career satisfaction,and Bootstrap test was used to explore the mediating effect of role stress.Results Organizational support had a positive effect on the career satisfaction of doctors in public hospitals,and for every unit increase in organizational support score,career satisfaction score will increase by 0.528 points.And role stress had a negative effect on the career satisfaction of doctors in public hospitals.Conclusion Organizational managers should take measures to promote the positive impact of organizational support on doctors'career satisfaction in public hospitals,reduce doctors'role stress,and continuously improve their career satisfaction.

Although great progress has been achieved in the techniques and materials of cardiopulmonary bypass (CPB), cardiac surgery under CPB is still one of the surgeries with the highest complication rate. The systemic inflammatory response is an important cause of complications, mainly characterized by activation of innate immune cells and platelets, and up-regulation of inflammatory cytokines. After activation, a variety of molecules on the membrane surface are up-regulated or down-regulated, which can amplify tissue inflammatory damage by releasing cytoplasmic protease and reactive oxygen species, and activate multiple inflammatory signaling pathways in the cell, ultimately leading to organ dysfunction. Therefore, the expression of these cell membrane activation markers is not only a marker of cell activation, but also plays an important role in the process of vital organ injury after surgery. Identification of these specific activation markers is of great significance to elucidate the mechanisms related to organ injury and to find new prevention and treatment methods. This article will review the relationship between these activated biomarkers in the innate immune cells and vital organ injuries under CPB.

Objective:To analyze independent influencing factors of surgical textbook outcome (TO) in patients with gallbladder carcinoma, and to establish a nomogram for predicting TO and evaluated the predictive ability.Methods:Patients with gallbladder carcinoma who underwent surgery in Department of Hepatobiliary and Pancreatic Surgery at Dongfang Hospital Affiliated to Shanghai Tongji University and Department of Biliary Tract Surgery Ⅰ, Third Affiliated Hospital of Naval Medical University (Shanghai Eastern Hepatobiliary Surgery Hospital) from January 2013 to December 2018 were included and the clinical features were retrospectively analyzed. A total of 232 patients were included, including 114 males and 118 females, aged (61.0±9.8) years. According to whether TO reached or not, they were divided into TO group ( n=86) and non-TO group ( n=146). Univariate and multivariate logistic regression were used to analyze the independent influencing factors of TO. The predictive nomogram model of TO was constructed. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive ability of the model, and the consistency of the predictive model was evaluated by the consistency curve graph and the Hosmer-Lemeshow test. Results:The 1-year and 3-years cumulative survival rates of patients with gallbladder carcinoma in the TO group (86.0% and 62.8%) were better than those in the non-TO group (46.6% and 27.3%), and the difference was statistically significant (χ 2=60.74, P<0.001). In multivariate analysis, higher T stage ( OR=0.16, 95% CI: 0.03-0.79, P<0.001) and cervical gallbladder cancer ( OR=0.14, 95% CI: 0.02-0.94, P=0.004) had the greatest negative association with a TO, and the higher the degree of tumor differentiation ( OR=7.08, 95% CI: 1.34-37.56, P=0.001), the easier it is to achieve TO. The ROC curve showed that the area under the curve of the predictive model was 0.84 (95% CI: 0.79-0.90), suggesting that the model had good predictive performance. A nomogram to assess the probability of TO was developed and had good accuracy in both the consistency curve and Hosmer-Lemeshow test (χ 2=5.77, P=0.673). Conclusion:Tumor T stage, tumor differentiation degree and tumor location are independent influencing factors for achieving TO in patients with gallbladder carcinoma after surgery. The nomogram model constructed according to the above conclusions could accurately predict the probability of reaching TO.

Remote pharmaceutical care refers to the process that pharmacists provide pharmaceutical care to patients remotely through information technology. Remote pharmaceutical care in China starts late and develops slowly. Therefore ，this paper discusses the pharmaceutical care modes that pharmacists at home and abroad can provide under the remote mode by collecting literature. The results show that foreign remote pharmaceutical care starts early and is relatively mature. The service mainly included remote follow-up and intervention ，24-hour online prescription and order review ，24-hour online drug reorganization ，and guidance on rational drug use in remote areas or community hospitals. The service population covers patients with cardiovascular disease ， diabetes，asthma，AIDS and so on. Some hospitals have established an integrated pharmaceutical care system of “Internet+Medical Consortium”in China ，with which pharmacists can provide patients with pharmaceutical care such as remote follow-up and intervention，drug consultation and so on. With the promotion of telemedicine ，domestic pharmacists can gradually expand the scope of services ，expand pharmaceutical services such as remote consultation and remote popular science push ，and realize the sharing of high-quality pharmaceutical care for the whole people.

Objective To understand the knowledge,attitude and behavior on health hazards of haze and secondhand smoke exposure among middle school students in Beijing,and provide us with guidance to carry out effective health education for middle school students.Methods A total of 1 294 students were selected randomly using stratified cluster sampling method;1 085 valid questionnaires were recovered.Among them,739 were junior high school students and 346 were senior high school students.The questionnaire included questions on middle school students' knowledge on haze and secondhand smoke exposure,their attitudes towards the judgement of severity of haze and secondhand smoke exposure and their utilization of protective measures when they are exposed to haze or secondhand smoke.Pearson's chi-squared test was performed to assess differences in knowledge,attitude and behavior between junior middle school students and senior high school students,boys and girls.Results Middle-school students' awareness rate on "the haze and exposure to secondhand smoke may cause respiratory disease" was the highest,which was 93.55％ and 95.76％ respectively.The awareness rate of the fact that haze,secondhand smoke exposure can cause cardiovascular disease was 38.99％ and 55.85％ respectively;while the rate of their awareness on the haze and exposure to secondhand smoke can lead to cancer was the lowest,which was 54.10％ and 69.95％ respectively.The differences was significant in the awareness rate of the fact that respiratory disease,cardio-cerebrovascular disease and cancer can be caused by the haze (x2=732.539,P＜0.05),likewise the differences were significant in the awareness rate of the above three kinds of diseases can be caused by secondhand smoke exposure (x2=460.291,P＜0.05).In the comparison between the severity of haze and smoking hazards,35.94％ of students believe that haze hazards is heavier than tobacco;48.02％ of the students think that the dangers of smoking is greater than haze;16.04％ of the students cannot determine the extent of damage of the haze and smoke.The proportion of students who think smoking was more harmful than haze was higher in junior high school group than in senior high school group.The two groups had a significant difference in the understanding of the severity comparison between haze and smoking (x2=13.014,P＜0.05).The differences between boys and girls in the view of the severity comparison between haze and smoking are also statistically significant,more boys believed smoking was more harmful than haze (x2=9.650,P＜0.05).In the aspect of protection from haze and secondhand smoke exposure,86.36％ of the students would like to protect themselves from haze,while 55.94％ of the students would take measures to prevent the secondhand smoke exposure initiatively,the junior high school students performed better than the senior high school students in this two aspects(x2=17.125,P＜0.05;x2=45.785,P＜0.05).Conclusion While middle school students have a certain understanding of the impact of haze and secondhand smoke exposure on health hazards,their understanding is limited.They have not paid enough attention to the harm of secondhand smoke exposure and their awareness of active refusal to secondhand smoke exposure needs to be improved.Schools should strengthen the health education for students and educate them not only to stay away from haze but also should be far away from secondhand smoke exposure.

Objective To investigate the clinical effects of painless concept in nursing of patients underwent urology outpatient surgeries. Methods From June to December 2014, according to the outpatient number, 100 patients underwent urology outpatient operation in our hospital were randomly divided into the control group and the observation group, with 50 cases in each group. Patients in the control group received routine nursing, while patients in the observation group received standardized pain assessment on the basis of routine nursing. Intervention measures were carried out and preemptive analgesia was used. Adverse drug reactions were evaluated and dealt with. Degree of pain, and satisfaction with pain control pf patients were assessed. The difference of 10 clinical nurses in knowledge and attitude towards pain management before and after the intervention was evaluated.Results The number of patients in the observation group with postoperative pain score ≥5 points and needing pain medication was 3 cases, while the number in the control group was 22 (χ2=19.26,P<0.01). The number of patients whose satisfaction score >90 was 46, while it was 38 in the control group (χ2 =4. 762, P<0. 05 ) . After training, the scores of 10 clinical nurses in pain management knowledge and attitude were significantly increased from (17.58±4.0) to (34.00±5.3) (t=7.820,P<0.01). Conclusions By promoting painless conception in outpatient operating nursing, we provide the patients with a scientific, standardized, and feasible working style of pain control. The overall satisfaction is improved, and pain management knowledge attitude of nurses in outpatient department are enhanced.

OBJECTIVETo investigate the relationship between cytogenetic markers with World Health Organization (WHO) classification, disease progress and prognosis in cases with primary myelodysplastic syndromes (MDS).

METHODS298 patients with de novo MDS from the first affiliated hospital of medical school, Zhejiang University were enrolled in the retrospective analysis of WHO classification, karyotype, and prognosis. Follow-up study was also conducted.

RESULTSThe WHO classifications at first diagnosis were as follows: refractory cytopenia with unilineage dysplasia (RCUD), 18 cases; refractory anemia with ring sideroblasts (RARS), 8 cases; refractory cytopenia with multiline dysplasia (RCMD), 104 cases; refractory anemia with excess blasts-1, 76 cases; refractory anemia with excess blasts-2, 85 cases; MDS unclassified (MDS-U), 5 cases involved; and single del (5q), 2 cases. 39.6% of MDS patients carried karyotypic abnormalities. Among them, the frequency of numerical abnormalities, structural abnormalities and the existence of composite abnormalities were 45, 31, and 42, respectively. The composite abnormalities were unbalanced translocations and complex chromosomal abnormalities. The incidence of both karyotypic abnormalities and complex chromosomal abnormalities in RAEB group was higher than that in non-RAEB group (P<0. 05). An analysis based on IPSS-R Scoring System showed that advanced risk stratification (except the low-risk group) gradually enhanced the incidence of karyotypic abnormalities (P<0.05). In addition, the probability of evolution to leukemia increased with the higher IPSS-R score (P<0.05). In RAEB group, the cases with +8 chromosome, accounting for 19.5% of karyotypic abnormalities, had worse prognosis than those with normal chromosomes.

CONCLUSIONKaryotype was identified with an independent risk factor in MDS patients. Therefore, the information on cytogenetic analysis was critical for diagnosis, prognosis and individual treatment. MDS patients presenting+8 chromosome, an intermediate risk factor, were associated with a poorer outcome compared to cases with normal chromosomes in RAEB group.
