Objective To evaluate the needs of performing a standardized communication skill training program for residents according to the differences in history taking mode of residents with different degrees and before and after the standardized training in Shanghai Changhai Hospital in 2010.Methods History taking modes of 81 residents in 2010 before and after the standardized training in Shanghai Changhai hospital were categorized.History taking modes were classified into:no effectiveness mode,traditional mode,disease-sickness mode and Calgary-Cambridge Guide mode.Distribution differences of history taking mode of residents with different medical degrees were analyzed by Fisher exact probability method (α =0.05).Distribution differences of history taking mode of residents before and after standardized training were analyzed by Pearson x2 test (α =0.05).Results 19.8％ residents took no effectiveness mode,53.0％ took traditional mode and 27.2％ used disease-sickness mode.There were significant differences in history taking modes among residents with different medical degrees (P =0.008).After training,history taking modes of residents were significantly changed (P=0.001),only 1.2％ residents used no effectiveness mode,59.3％ used traditional mode and 34.6％ used disease-sickness mode.But residents using the Calgary-Cambridge mode were not increased.Conclusions There are significant differences in history taking modes among residents with different medical degrees.History taking mode of residents changed after standardized training.But some of the residents still use non-optimal history taking modes; therefore a standardized communication skill training program might be needed in the future.

Objective To survey on knowledge of home blood pressure monitoring (HBPM) in community physicians of Zhejiang province.Methods One hundred and thirty eight community physicians from Xiacheng District of Hangzhou Municipality were assigned in intervention group (n =70) or control group (n =68).The knowledge of home blood pressure monitoring was surveyed by using the China HBPM questionnaire in both groups.Results Total 132 valid questionnaires were returned,including 70 from intervention group and 62 from control group.The results showed that 80.0％ (61/70) physicians in intervention group and 62.9％ in control group frequently suggested hypertensive patients to have HBPM in out-patient clinics (P ＜ 0.05).Physicians who correctly instructed patients to use upper arm electronic sphygmomanometer,to measure blood pressure in morning and night,to repeat 2-3 times each time,to record result 3 times,and to take ≥ 135/85 mmHg(1 mmHg =0.133 kPa) as criteria of hypertension in intervention and control groups were 67.1％ (47/70) versus 32.3％ (20/62),5.7％ (39/70) versus 29.0％ (18/62),92.9％ (65/70)versus 66.7％ (40/62),38.6％ (27/70)versus 6.4％ (4/62)and 57.1％ (40/70) versus 38.7％ (24/62),respectively,and the differences between two groups were all statistically significant (P ＜ 0.05).As for measuring frequency,92.9％ (65/70) physicians in intervention group and 67.7％ (42/62) in control group considered that blood pressure should be measured every day for poorly controlled patients ; 81.4％ (61/70) versus 14.5 ％ (9/62) considered that blood pressure should be measured every week for well-controlled patients; 87.1％ versus 35.5％ (22/62) considered that blood pressure should be measured every year at least for people with normal blood pressure; there were significantly differences between two groups (P ＜ 0.05).The community physicians generally considered that HBPM can be used to improve the awareness of hypertension for patients and to increase the blood pressure control rate in community.

Objective To analyze the association between β2-AK 27 locus genetic polymorphisms and asthma, and the protective effect in airway hyperreactivity. Methods The allel polymerase chain reaction were used to determine β2-AR 27 locus genetic polymorphisms in 149 patients with cough variant asthma who have the airway hyperreactivity. To observe these people for two years in order to know the proportion of changed to typical asthma. And compare with 90 people in healthy group. Results (1) The distribution frequency of β2-AR 27 locus genetic polymorphisms is major in heterozygote (57 % ) , and the Glu/Glu homozygote has the least ( 20% ) , (2) There was a significant decrease in the frequency of Glu/Glu genotype in asthmatics compared with healthy group(9% VS 20% ) ,OR = 0.4(P<0.05) ,95% CI (0.2 ～0. 9) ,but there was no significant difference in the allele frequency of asthmatics compared with healthy group,(3)The frequency of Glu/Glu genotype in severe asthma was lower than stable asthma group(P<0. 05). Conclusion These results suggesteded that β2-AR 27 locus genetic polymorphisms is correlated with asthma,and the Glu27 could have the protective effect to the airway.

Objective This study was conducted to assess the accuracy of [18F] fiuorodeoxyglucose-positron emission tomography/computed tomography (18FDG PET-CT) in detection of pelvic nodal metastases in endometrial cancer.Methods Patients with endometrial cancer from January 2015 to June 2017 confirmed by the postoperative pathology were retrospectively analyzed.30 patients finished PET-CT before operation.The findings on histopathology were compared with 18FDG-PET/CT findings to calculate the sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV),and accuracy of 18FDG-PET/CT.To analyze the efficacy of maximum standardized uptake (SUVmax) and lymph node maximum standardized uptake (LN-SUVmax) of PET-CT in the diagnosis of pelvic lymph node metastasis.Resuits For detection of pelvic nodes,based on patient analysis,18FDG-PET/CT had a sensitivity of 75.0％,specificity of 88.5％,PPV of 50.0％,NPV of 95.8％ and accuracy of 86.7％.Based on a nodal region analysis,18FDG-PET/CT had a sensitivity of 83.3％,specificity of 98.3％,PPV of 55.0％,NPV of 99.6％,and accuracy of 98.3％.When maximum standardized uptake values (SUVmax) ＞ 8,area under curve (AUC) =0.64,Yonden Index =0.42.When maximum standardized uptake values of lymphonodus (LN-SUVmax) ＞ 3 (AUC =0.79,Yonden Index =0.63),the sensitivity and specificity of diagnosis of lymph node metastasis were 100％,42.31％,and 75.0％,88.5％,but without statistically significant difference.Although AUC of LN-SUVmax was higher than SUVmax of primary lesion,but the difference was not statistically significant (P ＞ 0.05).Conclusions 18 FDG-PET/CT has high specificity,NPV for detection of pelvic LN metastasis area in endometrial cancer,which can provide preoperative basis for patients with endometrial cancer to avoid lymph node resection,thereby reducing the risk of early endometrial cancer surgery and improving the quality of life after surgery.We concluded that,there were no exact cutoffs of SUVmax for the prediction of lymph node metastases,neither primary lesion,nor lymph node.There is clearly a need for multicenter,large-scale trials to find out better parameters in judging metastasis of lymphnodes.

Objective:To evaluate the efficacy of holographic image technology in robot-assisted laparoscopic radical prostatectomy (RARP).Methods:The clinical data of 34 patients with prostate cancer who underwent RARP in our hospital during October 2020 and December 2020 was analyzed retrospectively. The average age of the patients was 67.8 (52-78) years. The mean BMI was 25.8 (18.0-32.3) kg/m 2. The median level of PSA before surgery was 13.4 (2-149) ng/ml. Median prostate volume was 31.7 (9.5-159.1) ml. EAU risk groups for biochemical recurrence of localised and locally advanced prostate cancer were list as below: 5 cases of low-risk, 7 cases of medium-risk, 22 cases of high-risk. There were 9, 16, 9 cases with the ASA score of 1, 2, 3 point, respectively. Preoperative Gleason score of 34 patients were list as below: 9 cases in score ≤6 group, 15 cases in score=7 group, 10 cases in score ≥8 group. For clinical stage before the surgery, 13 cases ≤T 2a stage, 1 case in T 2b stage, 20 cases ≥T 2c stage. The engineers established holographic images of 34 patients based on multiparametric magnetic resonance imaging (mpMRI) and the reports before the operation. Surgeons can obtain the size and location of tumors, surrounding neurovascular bundles visually by revolving, assembling, disassembling and concealing images, which was helpful for pre-surgery planning. By manipulating the holographic images extracorporeally, surgeons can discriminate Internal sphincter of urinary bladder and vesicoprostatic muscle, neurovascular bundles, membranous part, seminal vesicle easily, which improves the operation accuracy. Results:All 34 cases underwent operation successfully without transferring to open surgery. The median operative time was 157.5 (95-276) min with an estimated blood loss of 50 (20-300) ml. The median drainage removal time was 2 d and median hospitalization time was 3.5 d, respectively. The catheters were removed within an average time of 20.5 d. For postoperative Gleason score, there were 2 cases in score ≤6 group, 16 cases in score =7 group, 8 cases in score ≥8 group and 8 cases can’t make a score. For clinical stage after the surgery, 10 cases were ≤T 2a stage, 1 case was T 2b stage, 23 cases were ≥cT 2c stage. 22 cases underwent pelvic lymph node dissection, including a patient with right iliac fossa lymph node metastasis. There were 2 cases with positive surgical margin and 3 cases with Clavien-DindoⅠcomplications. The rate of 1-month and 3-month urinary continence were 47.1% and79.4%, respectively, 8 cases recovered erectile function after 3 month. Conclusions:Holographic image technology can promote cancer dissection completely, achieve urinary continence early and reduce perioperative complications tremendously. The technology is the "intraoperative security" for the accurate surgical treatment of prostate cancer.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been a major health burden in the world. So far, many strategies have been investigated to control the spread of COVID-19, including social distancing, disinfection protocols, vaccines, and antiviral treatments. Despite the significant achievement, due to the constantly emerging new variants, COVID-19 is still a great challenge to the global healthcare system. It is an urgent demand for the development of new therapeutics and technologies for containing the wild spread of SARS-CoV-2. Inhaled administration is useful for the treatment of lung and respiratory diseases, and enables the drugs to reach the site of action directly with benefits of decreased dose, improved safety, and enhanced patient compliance. Nanotechnology has been extensively applied in the prevention and treatment of COVID-19. In this review, the inhaled nanomedicines and antibodies, as well as intranasal nanodrugs, for the prevention and treatment of COVID-19 are summarized.

The traditional view is that breast reconstruction is not an option for day surgery center. As a result, few hospitals in the world conduct this operation in day surgery center. Endoscopic breast reconstruction with liposuction and robot-assisted breast reconstruction are minimally invasive surgeries for breast cancer patients, but they cannot be carried out in the day surgery center due to long operation time. The novel endoscopic-assisted immediate implant-based breast reconstruction after nipple sparing mastectomy through a single axillary incision for breast cancer patients has been successfully conducted in the day surgery center in our hospital due to short operation time and small trauma. Standardized management of the complete process from the patient selection to follow-up after discharge brings rapid recovery and few complications. At the same time, the development of endoscopic surgery makes the breast almost scarless and improves aesthetic results. Therefore, the mode of endoscopic-assisted reconstruction in the day surgery center of our hospital is expected to be popularized in the whole country.
