This paper reviewed the development history of doctor-patient shared decision-making （SDM） at home and abroad， emphasizing the importance of cross-cultural analysis in constructing a Chinese doctor-patient SDM model. It also delved into the relationship between Western “individualistic” sociocultural values and doctor-patient SDM， as well as the influence of China’s “collectivist” sociocultural values on doctor-patient SDM， revealing significant disparities in doctor-patient SDM models under distinct sociocultural contexts. Although the doctor-patient SDM theory in China originated from the West， this theory requires profound “collision” and adaptation with local Chinese culture to form a localized theory suited to China’s national conditions. Through cross-cultural adaptation and integrating China’s familism tradition and medical ethics concepts， the future construction of the doctor-patient SDM model in China should emphasize family members’ involvement and seek cultural balance to facilitate its widespread application in clinical practice.

OBJECTIVE To investigate the improvement effect and mechanism of desloratadine citrate disodium in mice with hypersensitivity pneumonitis （HP）. METHODS Sixty mice were randomly divided into blank control group （normal saline）， model group （normal saline）， prednisone group （positive control， 20 mg/kg） and desloratadine citrate disodium low-， medium- and high-dose groups （0.5， 1， 2 mg/kg）， with 10 mice in each group. Except for the blank control group， mice in other groups were intraperitoneally injected with ovalbumin （OVA） and exposed to OVA inhalation to establish the HP model. On day 22 post- modeling， mice in each group were administered the corresponding drugs or normal saline， once a day， for 11 consecutive days. After the last administration， lung function and airway hyperreactivity were assessed. The levels of interleukin-1β （IL-1β）， IL-4 and IL-6 in serum as well as the levels of IL-8， IL-13 and IL-17A in bronchoalveolar lavage fluid were determined. Pathological changes in lung tissue of mice were evaluated using Masson staining. Furthermore， the expressions of fibrosis-related proteins， including transforming growth factor β1 （TGF-β1）， type Ⅲ collagen （Col-Ⅲ） and fibronectin （FN） were determined in lung tissues. RESULTS Compared with the blank control group， the model group showed significant deterioration in lung function （P＜ 0.01）， while airway resistance and serum levels of IL-1β， IL-4， IL-6 and the levels of IL-8， IL-13 and IL-17A in the bronchoalveolar lavage fluid were increased significantly （P＜0.01）. The lung tissues exhibited alveolar collapse， atrophy， and structural disarray， along with the formation of extensive deposits of blue collagen fibers， the percentage of positive staining increased significantly （P＜0.01）. Additionally， the expression levels of TGF-β1， Col-Ⅲ， and FN proteins in the lung tissues were also increased significantly （P＜0.01）. After intervention with desloratadine citrate disodium， the pathological changes in the lung tissues of mice in each dosage group of desloratadine citrate disodium showed varying degrees of improvement， and most of the aforementioned indicator levels were significantly reversed （P＜0.05 or P＜0.01）. CONCLUSIONS Desloratadine citrate disodium can improve the lung function and airway hyperreactivity of HP mice， inhibit the release of inflammatory factors in serum and bronchoalveolar lavage fluid， and reduce the deposition of collagen fibers. Its mechanism of action may be related to anti-inflammatory， immunomodulatory， and antifibrotic effects.

Objective To analyze the impact of sarcopenia on the efficacy and adverse reactions of immunotherapy combined with chemotherapy in patients with advanced gastric cancer.Methods Patients with locally advanced or metastatic gastric cancer confirmed by pathology who were not eligible for radical surgery were selected as study subjects.A body composition analyzer was used to measure the appendicular muscle mass of the patients and calculate the skeletal muscle mass index(SMI).Based on the SMI,the patients were divided into sarcopenia group and non-sarcopenia group.On the basis of nutritional intervention and comprehensive exercise therapy,the patients were administered immu-notherapy combined with chemotherapy.The efficacy and adverse reactions were evaluated.The primary endpoint was progression-free survival(PFS),and the secondary endpoints were the objec-tive response rate(ORR)and treatment-related adverse reactions.Results A total of 52 gastric cancer patients were included,with 23 in the sarcopenia group and 29 in the non-sarcopenia group.The median PFS in the non-sarcopenia group was 9.8 months(95％CI,8.9 to 12.4),and was 5.4 months in the sarcopenia group(95％CI,4.9 to 8.1).The median PFS in the non-sarcopenia group was longer than that in the sarcopenia group,and the difference was statistically significant[HR(95％CI)=0.41(0.23 to 0.73),P=0.003].The results of the multivariate Cox propor-tional hazards regression model showed that comorbidities,treatment cycles,and sarcopenia were all independent prognostic factors affecting the PFS of gastric cancer patients(P＜0.05).The ORR in the non-sarcopenia group was 48.28％(14/29),and was 17.39％(4/23)in the sarcopenia group(x2=5.276,P＜0.05).Treatment-related adverse reactions with grading ≥3 in both groups were mainly hematological toxicities.In the non-sarcopenia group,the incidence of grading ≥ 3 treat-ment-related adverse reactions was 27.59％(8/29),and the incidence of grading＜3 treatment-re-lated adverse reactions(including those with no adverse reactions)was 72.41％(21/29).In the sarcopenia group,the incidence of grading ≥3 treatment-related adverse reactions was 56.52％(13/23),and the incidence of grading＜3 treatment-related adverse reactions(including those without adverse reactions)was 43.48％(10/23).The incidence of grading ≥3 treatment-related adverse reactions in the non-sarcopenia group was lower than that in the sarcopenia group(P=0.035).Conclusion For patients with locally advanced or metastatic gastric cancer complicated with sarcopenia,the median PFS of immunotherapy combined with chemotherapy is shorter,the ORR is lower,and the incidence of treatment-related adverse reactions is increased.Therefore,ear-ly intervention for sarcopenia should be implemented to improve the quality of life of patients with advanced gastric cancer.

This paper discusses from two aspects of case writing and PBL implementation experience. PBL cases should be based on professional requirements and reflect professional characteristics. Health inspection and quarantine cases targeted at application-oriented talent cultivation can be integrated into relevant experimental skills items. At the same time, the forms of case writing are expanded according to the differences of theme forms, which are designed as parallel cases and serial cases, so as to be applicable to the curriculum integration in different areas. In the implementation of PBL teaching, students' learning status is the key to the efficiency of classroom discussion, which determines whether the implementation of PBL is completely autonomous learning or embedded instruction. Teachers should establish cooperative learning atmosphere to improve the efficiency of classroom discussion

Objective:To understand the status quo of self-stigma of diabetic patients in college students and analyze its influencing factors.Methods:This study was a cross-sectional study, and the convenient sampling was conducted online and offline from July 2017 to June 2020. College students with diabetes who were treated in outpatient or inpatient Departments of Endocrinology and Metabolism in 5 Class Ⅲ Grade A hospitals were selected as the research objects, and similar patients who followed 2 diabetes public accounts were selected as online supplements. General information questionnaire and China-Self Stigma Scale (C-SSS) were used for questionnaire surveys. Data were statistically processed by t-test, analysis of variance and multiple linear regression analysis. A total of 200 questionnaires were distributed, and 189 valid questionnaires were recovered, with an effective recovery rate of 94.50%. The self-stigma of 80.42% of college students with diabetes mellitus was at a medium-to-high level. The total average score of C-SSS was (2.34±0.49) , of which the mean scores of cognitive dimension, emotional dimension and behavioral dimension were respectively (2.33±0.50) , (2.41±0.57) and (2.19±0.64) . The results of univariate analysis showed that there were statistically significant differences in the stigma scores of diabetic patients with different genders, family locations, parental physical conditions, diabetes types, family history, diabetes complications and insulin treatment or not ( P<0.05) . The results of multiple linear regression analysis showed that gender and type of diabetes were factors affecting the self-stigma level of college students with diabetes mellitus ( P<0.05) . Conclusions:The level of self-stigma in college students with diabetes mellitus is generally high. Hospitals, schools and families should strengthen cooperation and pay attention to these with high level of self-stigma. Meanwhile, early prevention and control should be targeted through dynamic tracking, psychological counseling and other interventions.

Rosmarinic acid (RA) is a natural polyphenolic compound that exists in many medicinal species of Boraginaceae and Lamiaceae. The previous studies have revealed that RA had therapeutic effects on hepatocellular carcinoma (HCC) in the H22-xenograft models by inhibiting the inflammatory cytokines and NF-κB p65 pathway in the tumor microenvironment. However, its molecular mechanisms of immunoregulation and pro-apoptotic effect in HCC have not been fully explored. In the present study, RA at 75, 150, and 300 mg/kg was given to H22 tumor-bearing mice via gavage once a day for 10 days. The results showed that RA can effectively inhibit the tumor growth through regulating the ratio of CD4⁺/CD8⁺ and the secretion of interleukin (IL)-2 and interferon-γ, inhibiting the expressions of IL-6, IL-10 and signal transducer and activator of transcription 3, thereby up-regulating Bax and Caspase-3 and down-regulating Bcl-2. The underlying mechanisms involved regulation of immune response and induction of HCC cell apoptosis. These results may provide a more comprehensive perspective to clarify the anti-tumor mechanism of RA in HCC.

OBJECTIVETo compare the difference between acupuncture and estazolam on arousal state in patients of primary insomnia, and to explore its nerve electrophysiology mechanism.

METHODSSixty-four patients of primary insomnia were randomized into an acupuncture group (32 cases) and a medication group (32 cases). After 3 patients were excluded, 31 cases in the acupuncture group and 30 cases in the medication group were included. Patients in the acupuncture group were treated with acupuncture at Sishencong (EX-HN 1), Anmian (Extra), Shenmen (HT 7), Sanyinjiao (SP 6), Zhaohai (KI 6), Shenmai (BL 62) as main acupoints, combined with supporting acupoints, once a day, five times per week, continuously for 4 weeks. Patients in the medication group were treated with oral administration of estazolam, once a day, continuously for 4 weeks. The Pittsburgh sleep quality index (PSQI) and mean sleep latency (MSL) of multiple sleep latency test (MSLT) were compared before and after treatment in the two groups; the polysomnography (PSG) was applied to monitor the indices regarding sleep structure.

RESULTSCompared before treatment, PSQI score was reduced after treatment in the two groups (both<0.01), which was more significant in the acupuncture group (<0.05). Compared before treatment, sleep onset latency (SOL), number of awakenings (NWAK) and wake after sleep onset (WASO) were reduced, while total sleep time (TST) and sleep efficiency (SE) were significantly increased in the two groups after treatment (all<0.01). Compared before treatment, the percentage of non-rapid eye movement period 1/2/3 (N1, N2, N3) and the percentage of rapid eye movement period (REM) to TST were not significantly changed after treatment in the medication group (all>0.05). Compared before treatment, the percentage of N1, N2 to TST was reduced, while the percentage of N3 and REM to TST was increased after treatment in the acupuncture group (<0.01). The SOL, NWAK, WASO, TST, SE were not statistically changed after treatment in each group (all>0.05). Compared with the medication group, the percentage of N1 and N2 was reduced while that of N3 and REM was increased after treatment in the acupuncture group (all<0.01). After treatment, MSL of MSLT were obviously decreased in the two groups (both<0.01), which were more significant in the acupuncture group (<0.05).

CONCLUSIONSAcupuncture can more effectively improve sleep quality of primary insomnia than estazolam, and is more beneficial for regulation of hyperarousal state.

BACKGROUND:The occurrence and severity of denture stomatitis are closely related to denture cleaning methods and wearing time. Therefore, it is of great significance to explore the effects of denture cleansers on denture surface roughness and color stability.OBJECTIVE:To investigate the effects of four different denture cleansers on the surface roughness and color stability of heat-curing denture base resins and elastic denture base materials by means of soaking test.METHODS: Samples of heat-curing denture base resins (n=25) and elastic denture base materials (n=25) were polished and soaked in NaClO, Efferdent, Polident partial, Polident overnight and water, respectively. The soak process was repeated 90 times. Then the color aberration and surface roughness were tested using color meter and roughmeter before soaking and after 30, 60, 90 times of soaking.RESULTS AND CONCLUSION:These four kinds of denture cleansers have greater influence on the elastic denture base materials than on the heat-curing denture base resins. With the increasing of soaking time, the color aberration and surface roughness of the two kinds of denture materials were increased gradualy after treatment with different denture cleansers, and the values were ranked as follows: NaClO > Efferdent > Polident overnight > Polident partial and water. To conclude, denture cleansers can induce the changes in denture surface roughness and color stability of heat-curing denture base resins and elastic denture base materials. NaClO exerts the strongest effect, followed by Efferdent and Polident overnight, and Polident partial exhibits the weakest effect.

BACKGROUND:In recent years, based on high-throughput molecular imaging, integration of genomics, proteomics and computer aided design and the application of correlative “technical chains” have achieved great achievements in the research of breast cancer, lung cancer, gastric cancer, colon cancer, ovarian cancer and melanin tumor. However, there are few researches on oral squamous cel carcinoma. OBJECTIVE:To detect the gene expression profile of the oral squamous cel carcinoma tissue and normal paracarcinoma tissue using DNA chip-based gene expression profile. METHODS:Two samples of oral squamous cel carcinoma tissue and normal paracarcinoma tissue of patients who received treatment at Stomatological Hospital of Guangdong Province of China in 2013 were included in this study. The gene expression profiles of oral squamous cel carcinoma and normal paracarcinoma tissue were determined by the Roche NimbleGen gene expression microarrays. RESULTS AND CONCLUSION: According to screening criteria of differential genes, 7 872 out of 32 448 detected genes were differentialy expressed genes of oral squamous cel carcinoma, which accounts for 24% of the total number of the screening genes. 3 800 genes were up-regulated, and 4 072 were down-regulated. The results confirm that through detection with the help of gene expression profile clip, 7 872 differentialy expressed genes were obtained through DNA chip-based gene expression profiles according to the screening criteria. Thus it can be concluded that the occurrence and development of the tumors are not a result of single or several genes. Previous experiments based on a single or several genes have great limitations. These findings also suggest that the occurrence of tumor is a result of mutual regulatory effects of many genes forming a network, moreover, the interactions of the network is quite complicated.
