The situational teaching of the course of introduction to medical humanities has some problems, such as low participation, poor communication, and lack of humanities thought. By reading text and creating text, narrative medicine can make students deeply participate in the scene, provide an intro-spective opportunity of being close to the patients, and make students better redefine the story of the other so as to be able to help patients to take a positive view of the disease. Therefore, by using the method of reading text and creating text of narrative medicine, this paper has studied the “4+3” situational teaching model reform of the course of “introduction to medical humanities”, analyzed the present situation and achievements and pointed out that the teaching should pay attention to the key elements, which is “to build a correct value view of medical humanistic, strengthen the emotional education of humanistic care, as well as culture humanistic knowledge and culture humanistic ability”, and it has also put forward some sugges-tions on improving the teaching level of“Introduction to medical humanities”in the future.

Objective To discuss effects of thoracoscopic lobectomy on early-stage non-small cell lung cancer .

Objective To evaluate the effect of electroacupuncture on endoplasmic reticulum stress in lung tissues of rats with acute lung injury (ALI) induced by endotoxin.Methods Forty healthy pathogen-free male Sprague-Dawley rats,aged 8 weeks,weighing 180-210 g,were divided into 4 groups (n=10 each) using a random number table:control group (group C),ALI group,electroacupuncture group (group E),and electroacupuncture at non-acupoint group (group NE).Lipopolysaccharide 5 mg/kg (in 0.5 ml normal saline) was injected intravenously to establish the model of endotoxin-induced ALI.Bilateral 30 min electroacupuncture stimulation of Zusanli and Neiguan acupoints was performed with the dispersedense wave (frequency 2/15 Hz,wave length 0.2-0.6 ms,intensity 1-2 mA) once a day (time for stimulation 9:30-10:30) for 4 consecutive days before and during establishment of the model in group E.Electroacupuncture was performed with the same parameters at the points 0.5 cm lateral to the acupoints of Zusanli and Neiguan in group NE.At 6 h after lipopolysaccharide injection,the rats were sacrificed,and lungs were removed for microscopic examination and for determination of wet to dry weight ratio (W/D ratio),apoptosis in alveolar epithelial cells and expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP) and caspase-12 in lung tissues (by Western blot).The pathological changes of lungs were scored.Apoptosis index (AI) was calculated.Results Compared with group C,lung injury scores,W/D ratio and AI were significantly increased,and the expression of GRP78,CHOP and caspase-12 in lung tissues was up-regulated in the other three groups (P＜0.05).Compared with group ALI,lung injury scores,W/D ratio and AI were significantly decreased,and the expression of GRP78,CHOP and caspase-12 in lung tissues was down-regulated in group E (P＜0.05),and no significant change was found in the paramneters mentioned above in group NE (P＞0.05).Conclusion The mechanism by which electroacupuncture attenuates endotoxin-induced ALI is related to inhibition of endoplasmic reticulum stress and reduction of apoptosis in alveolar epithelial cells in rats.

Background: The use of molecular categorisation is shifting paradigm towards the use of molecular information to refine risk stratification in endometrial cancer (EC). To date, evidence to support molecular-guided therapies is limited to retrospective studies and secondary molecular analyses of patients receiving standard treatment. The PROBEAT study is the first randomized phase III trial to evaluate tailored adjuvant treatment based on WHO-endorsed molecular classification in Chinese EC patients. It is expected to provide a clinical decision-making tool for adjuvant treatment of patients with high-intermediate risk (HIR) or intermediate risk (IR) EC to better optimise and personalise patient care and increase relapse-free survival. Methods The PROBEAT trial is a prospective, multicentre study led by Women’s Hospital of Zhejiang University Gynaecologic Oncology Group. Recruitment started on January 24, 2022, and 590 patients with HIR or IR endometrioid EC are expected to be recruited from 13 clinical centres in China. All tumor tissues will be classified into four molecular subtypes (POLEmut, MMRd, p53abn, or NSMP) based on WHO-endorsed molecular classification. Patients will be randomly assigned at a 2:1 ratio to either experimental arm and will receive molecular profile-based adjuvant treatment (observation in the POLEmut subgroup, vaginal brachytherapy in the MMRd or NSMP subgroup, or chemoradiotherapy in the p53abn subgroup) or to standard arm and will receive preferred adjuvant radiotherapy as recommended by the recent National Comprehensive Cancer Network guidelines version 1 (2022). The primary outcome is 3-year rates of recurrence. Secondary outcomes are relapse-free survival, overall survival, adverse events and health-related cancer-specific quality of life.

Objective:To analyze the passive smoking exposure and its influencing factors in non-smokers aged≥18 in Tianjin.Methods:This was a cross-sectional study. Based on the 2018 Tianjin Adults Noncommunicable Disease and Nutrition Surveillance, non-smokers aged≥18 years old at 7 surveillance sites were selected as the research objects, taking 2018 population data of Tianjin as the standard population, the sample data were weighted to analyze the general demographic characteristics, the level of passive smoking exposure, the cognition of tobacco harm, and the influencing factors of passive smoking exposure. Pearson χ 2 test was used to compare the rate between groups, and the influencing factors were analyzed by unconditional logistic regression. Results:After weighted, the passive smoking exposure rate was 51.5%, among non-current smokers, the awareness rates of smoking related lung cancer and passive smoking related adult lung cancer were 83.3% and 80.0%, respectively. The awareness rates of smoking related stroke and passive smoking related heart disease in adults were 61.4% and 66.4%, respectively. The awareness rate that smoking related stroke was higher in the non-passive smoking exposed group than in the secondhand smoke exposed group (62.7% vs 60.3%, P<0.05). There was no statistical difference in the awareness rate of smoking related heart attacks and lung cancer as well as passive smoking related adult heart disease, adult lung cancer, and lung disease in children between the passive smoking exposed group and the non-passive smoking exposed group (all P>0.05). The awareness rate of smoking related three diseases (stroke, heart attack and lung cancer) was 57.9% and the awareness rate of passive smoking related three diseases (heart disease in adults, lung cancer and lung disease in children) was 64.9% in non-current smokers. Among men, undergraduate or above was a protective factor for second-hand smoke exposure. Heads, clerical and related personnel of state organs, party and mass organizations, enterprises and public institutions were risk factors for secondhand smoke exposure. Among women, age ≥60 years and high education were protective factors for secondhand smoke exposure. Conclusions:Non smokers aged 18 and above in Tianjin have a higher level of passive smoking exposure, and the awareness rate of tobacco exposure related cardiovascular diseases is low. In future, the health education of relevant knowledge should be strengthened.

OBJECTIVETo assess the relationship of homozygous deletion status of p16 (MTS1/INK4a/CDKN2A), p15(MTS2/INK4b/CDKN2B) genes and laryngeal squamous cell carcinoma(LSCC) progression.

METHODSDNA was extracted from fresh tumors. Homozygous deletion of p16 exon 2(p16E2) in 80 cases of LSCC and p15 exon 2(p15E2) in 67 cases of LSCC were detected by the polymerase chain reaction technique.

RESULTSThe p16E2 deletion rate in 80 cases was 12.5%(10/80); the p15E2 deletion rate in 67 cases was 11.94%(8/67); the p16E2 and p15E2 codeletion rate in 67 cases was 5.97%(4/67).

CONCLUSIONHomozygous deletion of p16E2 and p15E2 is related with LSCC oncogenesis, and it may play a role to some extent in LSCC malignant progression.

Objective:To evaluate the risk of HBV recurrence after liver transplantation in patients with end-stage hepatitis B related liver disease, and to explore the indications for antiviral therapy withdrawal.Methods:The data of HBV DNA, cccDNA in liver puncture tissues and peripheral blood in 31 patients after liver transplantation was retrospectively analyzed.Results:Among the 31 patients, 15 (48%) had detectable and quantified HBV DNA in liver biopsy tissue, while their HBV related serological indicators were negative, suggesting an occult HBV infection in some patients. The study found 15 out of 19 cases who were taking Entecavir were cccDNA negative (78.9%), compared to 5 out of 12 cases (41.6%) in Lamivudine regiment ( P=0.03). Conclusions:Hidden HBV infection can be detected by amplifying cccDNA and HBV DNA in liver puncture tissue by using ddPCR. Entecavir is superior to lamivudine in the clearance of cccDNA.

OBJECTIVE To calculate the cost of centralized dispensing of four categories of drugs （ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions） in pharmacy intravenous admixture service （PIVAS）， and provide reference for setting charging standards for relevant departments. METHODS The operating costs of PIVAS in 12 medical institutions from Shaanxi province were collected through questionnaire survey， including labor costs， medical and health material costs， fixed asset depreciation and repair costs， water and electricity costs， and management costs. The operation time allocation coefficient method and workload allocation coefficient method were comprehensively used to allocate the above costs， and the unit preparation costs of four categories of drugs were calculated. RESULTS The average annual total costs of dispensing ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions in Shaanxi province were （2 195 900.25±1 680 893.73） yuan， （746 341.59±725 839.39） yuan， （331 420.15±183 258.83） yuan， and （330 322.68±277 281.70） yuan， respectively， with labor costs accounting for the highest proportion， averaging 85.49%. The costs of dispensing a set of ordinary drugs， antibacterial drugs， and hazardous drugs were 5.89， 7.60， and 14.37 yuan， respectively； the cost of dispensing one bag of parenteral nutrition solution was 32.15 yuan （excluding the cost of disposable intravenous nutrition bags）. CONCLUSIONS The cost calculation method and data of different types of intravenous drugs obtained in this study can provide reference for relevant departments to formulate and adjust PIVAS fee standards.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.
