A series of 2-methoxyestradiol (2-MeO-E2) RGD peptide conjugates with coupling RGD peptides to 3- position or 17-position of 2-MeO-E2 through space linker were synthesized. Their antiangiogenic properties were preliminarily evaluated by cell migration scratch assays against HUVECs. Compound 26c binding RGDV peptide showed the best inhibitory effect. In addition, all 2-MeO-E2 RGD peptide conjugates exhibited obvious activity. These results demonstrate that conjugates with RGD peptides represent a promising means for targeting angiogenesis in cancer therapy.
2.Advances in PI3Kδ selective inhibitors
Journal of China Pharmaceutical University 2016;47(5):503-510
Phosphoinositide 3-kinase(PI3K), a key regulator in the PI3K/AKT/mTOR signaling pathway, plays a critical role in regulation of cell growth, differentiation, metastasis apoptosis, and angiogenesis processes. Abnormal activation of PI3K is closely related to the development of many types of human cancers. PI3Kδ is an important isoform of PI3K family, mainly expressed in leukocytes, which makes it an attractive target for the treatment of hematological malignancies. Great efforts in both industry and academia have been made to develop PI3Kδ selective inhibitors as anti-cancer agents. This review attempts to provide an overview of recent advances in the research of PI3Kδ selective inhibitors, fueling the progress of the ideal selective PI3Kδ inhibitors in the future.

Objective: To determine the knowledge of influenza, pneumonia, herpes zoster and related vaccines, willingness to vaccinate under multiple payment scenarios, and corresponding risk factors among people over 50 years old in Minhang District of Shanghai. Methods: A total of 1 672 respondents aged 50-69 from 13 communities/towns in Minhang district of Shanghai were included in this study using a stratified random sampling strategy on December 2020. The knowledge of influenza, pneumonia, herpes zoster and vaccines was investigated using a questionnaire, and the differences in the willingness under multiple payment scenarios were determined using chi-square test. The consistency in the willingness under multiple payment scenarios was compared using Cohen's Kappa and the risk factors of the willingness was determined using ordinal logistic regression. Results: The average age of 1 672 respondents was (60.48±5.96) years old, including 777 (46.47%) males and 895 (53.53%) females. A total of 1 350 subjects (80.74%) had local household registration in Shanghai. The proportion of the willingness to vaccinate for themselves, spouses, and parents under any payment scenario was determined to be 80.6% (influenza vaccine), 81.5% (pneumonia vaccine), and 74.0% (herpes zoster vaccine). The willingness to vaccinate against influenza and pneumonia under multiple payment scenarios remained stable (Kappa value ≥0.6), while that against herpes zoster infection was inconsistent (Kappa value ≤0.35). Logistic regression analysis showed that respondents who had higher knowledge of influenza and influenza vaccine [OR (95%CI): 1.111 (1.054-1.170), 1.182 (1.126-1.240), respectively], aged 50-59 [1.305 (1.085-1.531)] and local household registration in Shanghai [1.372 (1.079-1.721)] had higher willingness to vaccinate against influenza, while males had lower willingness [0.733 (0.551-0.910)]. Respondents who had higher knowledge of pneumonia and pneumonia vaccine [OR (95%CI): 1.837 (1.152-2.517), 2.217 (1.541-2.893), respectively] had higher willingness to receive pneumonia vaccine. Respondents aged 50-59 [1.327 (1.059-1.537)] and with local household registration in Shanghai [2.497 (1.417-4.400)] were more likely to be vaccinated against herpes zoster, while those with middle school degree or below [0.664 (0.396-0.992)] and high school degree [0.559 (0.324-0.964)] were less likely to be vaccinated. Conclusion: Among people aged over 50 years old in Minhang district of Shanghai, the willingness to vaccinate for themselves, spouses, and parents against influenza, pneumonia and herpes zoster infection is quite different under multiple payment scenarios, especially for herpes zoster vaccine.

Objective:To characterize the mortality rate of residents in Minhang District of Shanghai from January to April in 2016-2020, and to determine the change in the epidemic Coronavirus Disease 2019 (COVID-19) in 2020. Methods:Data of mortality surveillance was collected from the death registry of Shanghai residents. Cause of death was coded and classified per the International Classification of Diseases (ICD-10). The standardized mortality rate was calculated based on the standard population of China in 1990. The analysis was performed by Excel 2016 and SPSS 20.0. Results:From 2016 to 2020, the average crude mortality rate of residents was 281.75/100 000 from January to April in Minhang District of Shanghai, and the standardized mortality rate was 66.57/100 000. The top five causes of death in the latest five years were cardiovascular diseases, tumor, respiratory diseases, endocrine diseases, and injury and poisoning. The mortality rate was the lowest from January to April in 2020 in the past five years; furthermore, the mortality rate of respiratory system diseases has decreased significantly. Conclusion:Sex, age, place and causes of death in residents are consistent from January to April across years in Minhang District of Shanghai. However, there are minor differences in 2020, which may be attributable to the epidemic of COVID-19.

ObjectiveTo compare the efficacy between the Mycob.T scanner system and manual microscopy for detecting acid-fast bacilli in sputum specimens. MethodsBetween January and November 2020, a total of 1 519 sputum samples from suspected primary tuberculosis patients from 5 designated tuberculosis hospitals in Shanghai were examined by Smear and BACTEC MGIT 960 liquid culture (liquid culture) methods. Each specimen was subiected to 2 direct smear slides. One slide was stained by Z-N method and examined with manual microscopic method. Another slide was stained and scanned by the Mycob.T system. The efficacy of manual microscopy and the Mycob.T scanner system for detecting acid-fast bacilli in sputum specimens was compared based on the result of liquid culture. Results of the repetitive scanning by the Mycob.T scanner system and the recheck of the manual microscopy were analyzed. ResultsThe average positive rate by the Mycob.T scanner system was 14.4% (219/1 519) while the average positive rate by manual microscopy was 16.3% (248/1 519). No significant difference was observed (χ2=2.13, P=0.145). Based on liquid culture confirmation results, the sensitivity of manual microscopy (60.36%) was higher than that of the Mycob.T scanner system (52.94%), and the difference is statistically significant (χ2=4.38, P=0.036). Both methods had high specificity (98.94%). The concordance of the Mycob.T scanner system and manual microscopy was 95.46%, with the kappa value of 0.826. The results of repeatability test of the Mycob.T scanner system and the recheck results of the manual microscopy showed that the coincidence rate of scanning by the Mycob.T scanner system was 99.5% (436/438), and the recheck coincidence rate by the manual microscopy was 98.6% (432/438). ConclusionThe Mycob.T scanner system have high specificity for detecting acid-fast bacilli in sputum samples and good consistency with the results of manual microscopy. Compared with manual microscopic examination, the Mycob.T scanner system can greatly alleviate the work intensity.

ObjectiveTo obtain the status of latent tuberculosis infection (LTBI) among tuberculosis (TB)-related health-care workers (HCWs) in Shanghai, and to explore the risk factors related to TB infection. MethodsA multi-center cross-sectional study was conducted by recruiting medical workers from multiple designated TB hospitals, centers for disease control and prevention, and community health service centers in Shanghai. Each subject was required to complete a questionnaire and to provide a blood sample for TB infection test. Univariate and multivariate analysis ware made in order to find risk factors relating to TB infection. ResultsA total of 165 medical workers were recruited, and the proportion of TB infection was 16.36% (95%CI: 11.49%‒22.76%). Multivariate logistic analysis showed that clinical doctors and nurses (adjusted OR=9.756, 95%CI: 1.790‒53.188), laboratory staffs (adjusted OR=78.975, 95%CI: 8.749‒712.918), and nursing and cleaning workers (adjusted OR=89.920, 95%CI: 3.111‒2 598.930) had higher risk of TB infection. ConclusionThe overall LTBI prevalence among TB-related HCWs is low. However, working as doctors, nurses, laboratory staffs, nursing workers and cleaning workers are risk factors of TB infection. TB-related HCWs who work at hospitals are at risk of TB infection comparing to medical staffs who work outside hospitals.

Objective: To explore the promotion effect of laparoscopic standardized surgery for gastric cancer observational in some regional medical centers in Shanghai. Methods: A retrospective cohort study was carried out. Eleven regional medical centers in Shanghai received the promotion program of laparoscopic standardized surgery for gastric cancer, which was led by Ruijin Hospital, Shanghai Jiaotong University School of Medicine (Shanghai Minimally Invasive Surgery Center) from January to December 2020. Clinicopathological data of gastric cancer patients treated at these 11 regional medical centers before and after the promotion program were collected. Inclusion criteria were as follows: patients undergoing laparoscopic distal gastrectomy or total gastrectomy; gastric cancer confirmed by pathology; without distant metastasis or peritoneal metastasis. Patients who did not undergo laparoscopic D2 radical resection, or received neoadjuvant chemotherapy before surgery, or without complete clinical data were excluded. Patients undergoing laparoscopic surgery from January to December 2019 were included in the pre-promotion group (46 cases). Patients undergoing laparoscopic surgery from January to December 2021 were included in the post-promotion group (102 cases). In addition, patients undergoing laparoscopic surgery at Ruijin Hospital from January 2021 to December were included in the control group (138 cases). The baseline data, perioperative measurements postoperative complications, and pathological results of the three groups were analyzed and compared. Results: There were no significant differences in baseline characteristics among the three groups (all P>0.05). Compared with the pre-promotion group, the operation time in post-promotion group was significantly shorter [(207.3±36.0) minutes vs. (254.2±47.1) minutes, t=7.038,P<0.001], and the number of harvested lymph node was significantly more (24.4±12.2 vs. 18.9±5.5, t=2.900, P=0.004). However, there were no significant differences in the extent of resection, time to fluid intake, and postoperative hospital stay between the two groups (all P>0.05). Compared with the control group, the operation time [(207.3±36.0) minutes vs (172.6±26.0) minutes, t=8.281, P<0.001], time to fluid intake [(6.3±3.2) days than (5.5±3.0) days, t=2.029, P=0.044], and the postoperative hospital stay [(14.3±5.6) days vs. (10.1±4.8) days, t=6.036, P<0.001] in the post- promotion group were still longer. Total gastrectomy was less common in the post-promotion group compared with the control group [18 cases (17.6%) vs. 41 cases (29.7%), χ2=7.380, P=0.007]. However, there was no significant difference in the number of harvested lymph node between the two groups (P>0.05). The morbidity of postoperative complication in the post-promotion group (9.8%, 10/102) was significantly lower than that in the pre-promotion group (23.9%, 11/46) (χ2=5.183, P=0.023), while above morbidity was not significantly different between the post-promotion group and the control group [9.8% vs. 6.5% (9/138), χ2=0.867, P=0.352]. Conclusion: After the promotion of laparoscopic standardized surgery for gastric cancer in regional medical centers, the standardization degree of surgery has been improved, and the morbidity of postoperative complication decreases. Laparoscopic standardized surgery for gastric cancer can be promoted to more regional medical centers.
