ObjectiveTo understand the prevalence of tobacco use among residents aged 15 years old and above in Jiading District of Shanghai, and to provide a scientific basis for formulating effective regional tobacco control policies. MethodsThe Probability Proportional to Size (PPS) sampling method was employed to select one neighborhood committee (village) from each of Jiading District’s 11 subdistricts as survey monitoring sites. From the household registry of each selected neighborhood committee (village), 50 residential households were randomly sampled, resulting in a total of 550 households surveyed. Within each selected household, one permanent resident aged 15 years old or above was randomly chosen to complete the questionnaire. The content covered general information, exposure to secondhand smoke, awareness of tobacco related health hazards, etc. Statistical analyses were performed using SPSS 27.0 software. ResultsA total of 550 questionnaires were distributed, with 549 valid responses collected, and the effective response rate was 99.82%. The survey findings revealed that in 2023, the current smoking rate among individuals aged 15 years old and above in Jiading District of Shanghai was 18.76%, with males accounting for 38.93% and females accounting for 2.62%. Male gender was identified as a relative factor for smoking (OR=34.108, 95%CI: 14.440‒80.722), whereas higher education attainment emerged as a protective factor against smoking (OR=0.388, 95%CI: 0.184‒0.820). Among non-smokers aged 15 years old and above in Jiading District, the secondhand smoke exposure rate was 46.86%, with statistically significant differences observed across different age groups and occupations (P<0.001). Restaurants exhibited the highest secondhand smoke exposure rate of 42.14%, followed by households bearing (36.79%). The overall awareness rate among individuals aged 15 years old and above in Jiading District regarding four smoking-related diseases, namely stroke, heart disease, lung cancer, and impotence, was 48.45%, while the awareness rate for three secondhand smoke-induced diseases, namely adult heart disease, pediatric pulmonary disease, and adult lung cancer, was 64.29%. ConclusionThere is still room for reduction in the prevalence of tobacco use among individuals aged 15 yeas old and above in Jiading District. The exposure to secondhand smoke is severe, and residents have low awareness of the harm of tobacco. Tobacco control law enforcement should be strengthened, smoke-free-home health education should be included in tobacco control efforts, and targeted health education should be carried out.

Objective To investigate the effect of Osteoporosis Self-Assessment Tool for Asia(OSTA)index on brachial ankle pulse wave velocity(baPWV)and its predictive value for peripheral atherosclerosis in menopausal women.Methods A total of 1 138 menopausal women who underwent physical examination at our hospital from January 2022 to December 2022 were enrolled in the study.General clinical data were collected,the OSTA index was calculated,and baPWV was measured.Patients were divided into the control group(n=539)and the peripheral atherosclerosis group(n=599)according to the baPWV values(peripheral atherosclerosis occurs with baPWV≥1 400 cm/s).Linear regression and Logistic regression were used to analyze the effect of OSTA index on baPWV in menopausal women.The predictive value of peripheral atherosclerosis was evaluated using the receiver operating characteristic(ROC)curve.Results The OSTA index was lower in the peripheral atherosclerosis group than that in the control group[-0.40(-2.20,1.00)vs.0.40(-0.60,1.40),P＜0.05].Univariate linear regression analysis was used to conclude that the OSTA index was an influencing factor of baPWV,and after correcting for risk factors,multivariate linear regression analysis indicated that OSTA index still affected the value of baPWV(P＜0.05).The linear regression equation was baPWV=-27.911-39.752×OSTA+6.444×SBP+7.008×DBP+11.506×HCY+27.942×Hs-CRP.Logistic regression analysis suggested that increased OSTA index was a protective factor for peripheral atherosclerosis(OR=0.664,95%CI:0.535-0.823,P＜0.001).ROC curve analysis suggested that OSTA index was-1.25 as the optimal cutoff point,which predicted peripheral atherosclerosis with an area under the curve of 0.619,a sensitivity of 36.2%and a specificity of 86.3%.Conclusion In menopausal women,OSTA index is an influential factor for baPWV,and increased OSTA index is a protective factor against peripheral atherosclerosis,which can be used to predict baPWV value.

In order to understand the current status of the knowledge, attitude and practice (KAP) about prevention and control of COVID -19 in college students, and to provide theoretical basis for prevention and control work in college campus. This study investigated the KAP of COVID -19 of 1 847 college students in Shaanxi province by questionnaire using the convenience sampling method. Chisquare test and multivariate logistic regression analysis were used to analyze the influencing factors for the KAP of COVID -19. The results demonstrated that 48.3% of the students had a higher knowledge level of COVID -19, 11.7% had a fear attitude and 39.6% had good protective practices. Logistic regression results showed that female and urban household college students had higher cognitive level of COVID -19. The college students with anxiety state were more likely to have fear attitude. Students of female, urban household, anxiety, higher cognition and fear attitude showed better protective practices. The above results indicated that the knowledge level of COVID -19 in college students are not enough, and the attitude and protective practices need to be further improved. Therefore, relevant departments should follow the rules of KAP, carry out targeted propaganda and education on COVID -19 for college students, to improve their ability to cope with public health emergencies.

Lung cancer tops the disease list in the world due to the high incidence and mortality， and about 85% of lung cancer cases is non-small cell lung cancer （NSCLC）. Most NSCLC patients are in the advanced stage at the time of diagnosis， with a low 5-year survival. Traditional Chinese medicine （TCM） plays a role in the comprehensive treatment of malignant tumors. Oral Chinese patent medicines， as an important part of TCM， have the advantages of stable preparations， mild taste， simple package， and accurate effective ingredients， which are different from decoctions. They have been widely used in the adjuvant treatment of NSCLC. In clinical practice， the combination of oral Chinese patent medicines with chemotherapy， targeted therapy， or radiotherapy， as well as the application of the oral Chinese patent medicines alone， can increase efficiency， reduce toxicity， prolong the survival time of patients， and improve the quality of life. The mechanisms of oral Chinese patent medicines in the treatment of NSCLC mainly include inhibiting the proliferation， invasion， and metastasis of lung cancer cells， promoting the apoptosis of lung cancer cells， inhibiting tumor neovascularization， reversing multidrug resistance， and regulating the immune functions， which reflects the multi-pathway and multi-target manner of TCM. The oral Chinese patent medicines commonly used in the clinical treatment of NSCLC include Jinfukang oral liquid， Shenyi capsules， Pingxiao capsules， Xiao'aiping tablets， Kanglaite capsules， compound Cantharis capsules， Huisheng oral liquid， Yangzheng Xiaoji capsules， Xihuang pills， Zilongjin tablets， and Cinobufagin capsules. There are many clinical and basic studies about the treatment of NSCLC with these medicines， while a systematic review remains to be carried out. Therefore， we systematically reviewed the mechanisms and clinical application of commonly used oral Chinese patent medicines in the adjuvant treatment of NSCLC， aiming to provide reference for follow-up research and clinical treatment.

Objective:To explore the clinical phenotype and genotype of a family with hereditary hypofibrinogenemia.Methods:Activated partial thrombin time (APTT), prothrombin time (PT),thrombin time (TT) and thrombelastogram (TEG) were tested in all family members. Fibrinogen activity and antigen were detected by Clauss method and immunoturbidimetric method respectively. All exons and flanking sequences of fibrinogen FGA,FGB,FGG genes were analyzed by PCR, and the products were subjected to Sanger sequencing.Results:The proband represented prolonged PT and TT, low Fg activity and antigen, elevated K value and decreased Angle value in TEG. Other family members reported similar changes including proband′s father,daughter and son, and his elder brother and his niece. Exon 5 c.510_512 of FGG gene in the proband revealed a minor deletion mutation.Conclusion:The novel heterozygous missense mutation of exon 5 c.510_512del (Gln170_Ile171 del ins His) of FGG gene is the molecular mechanism that leads to hereditary hypofibrinogenemia in this family.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) for the prenatal diagnosis of a fetus with structural anomaly detected by ultrasonography. METHODS: The fetus and its parents were subjected to chromosomal karyotyping and CMA analysis. RESULTS: The fetus was found to carry a 46,XN,t(8;11)(q21.2;q13) translocation which was inherited from its mother. CMA has found no copy number variations (CNVs) in both parents but a de novo 2.00 Mb microdeletion in the fetus at 8q13.3. CONCLUSION CMA is capable of detecting microdeletions and microduplications in fetuses with translocations detected by karyotyping analysis.

Objective:To evaluate the effect of patient-controlled intravenous analgesia (PCIA) with dexmedetomidine mixed with subanesthetic dose of ketamine on anxiety and depression in the patients with advanced cancer pain.Methods:Sixty patients of either gender with advanced cancer pain, aged 24-82 yr, with poor analgesic effect or obvious adverse reactions after three-step analgesic treatment, were selected and randomly divided into 2 groups ( n=30 each) using a random number table method: routine treatment group (group R) and dexmedetomidine mixed with ketamine group (group DK). The initial dose of morphine for PCIA was 1/3 of the oral dose in group R. In group DK, ketamine 5.4 mg/kg (90 μg·kg -1·h -1) and dexmedetomidine 6 μg/kg (0.1 μg·kg -1·h -1) were added on the basis of group R. Tropisetron 8 mg was added to analgesics and diluted to 200 ml with normal saline in both groups.The analgesic pump was programmed to deliver 4 ml with an initial dose of 4 ml, lockout interval of 15 min and background infusion at 4 ml/h.The numerical rating scale score, Ramsay sedation score, Chinese version of State-Trait Anxiety Inventory score and Beck Depression Inventory-Ⅱ score were recorded before PCIA and at 4, 12, 24 and 48 h of PCIA.The development of effective analgesia and satisfactory sedation, occurrence and degree of depression, score for patient's quality of life and satisfaction score, consumption of morphine and adverse reactions such as constipation, nausea and vomiting, agitation and respiratory depression were recorded within 48 h of PCIA. Results:Compared with group R, the NRS score was significantly decreased, the rate of effective analgesia was increased, Beck Depression Inventory-Ⅱscore and Chinese version of State-Trait Anxiety Inventory score were decreased, the incidence and degree of depression were decreased, incidence of nausea and vomiting and constipation, consumption of morphine and pressing times of PCIA pump were decreased, and the score for patient's quality of life and satisfaction score were increased in group DK ( P<0.05). Conclusion:PCIA with dexmedetomidine mixed with subanesthetic dose of ketamine can significantly enhance the analgesic effect, improve anxiety and depression, and raise the quality of life when used for the patients with advanced cancer pain.

Objective:To assess the therapeutic efficacy and histopathological effect of photodynamic therapy (PDT) with intralesional injection of aminolevulinic acid (ALA) in a rat model of acneiform inflammatory nodules.Methods:Forty specific pathogen-free (SPF) SD rats were randomly and equally divided into normal control group, model control group, ALA injection group and topical ALA group. Rats in the normal control group received no treatment, and those in the other 3 groups were inoculated with Propionibacterium acne suspension on the right auricle for the establishment of a rat model of acneiform inflammatory nodules. After successful modeling, rats in the model control group received no other treatment, those in the ALA injection group were intranodularly injected with 5% ALA followed by red light irradiation, and those in the topical ALA group were topically treated with 5% ALA on the acneiform inflammatory nodules followed by red light irradiation. The treatment was performed once a week for 2 weeks. Twenty-four hours after the last treatment, general appearance and histopathological changes of rat ears were observed in each group, the thickness of rat auricles was measured, and liver and kidney functions were evaluated. Statistical analysis was carried out by using one-way analysis of variance and least significant difference- t test for comparisons among the groups. Results:The thickness of rat auricles significantly differed among the normal control group, model control group, topical ALA group and ALA injection group (0.435 ± 0.006, 1.269 ± 0.071, 1.088 ± 0.098, 0.699 ± 0.095 mm, respectively, F = 235.60, P < 0.001) , and was significantly higher in the model control group than in the normal control group, topical ALA group and ALA injection group ( t = 24.18, 5.24, 16.48 respectively, all P < 0.01) , but significantly lower in the ALA injection group than in the topical ALA group ( t = 11.24, P < 0.01) . Compared with the model control group, the topical ALA group and ALA injection group showed decreased degree of local redness and swelling as well as number of nodules on the rat auricle, and decreased quantity of infiltrating inflammatory cells in the dermis and subcutaneous tissues. Compared with the topical ALA group, nodules regressed more markedly in the ALA injection group, and no clumps of inflammatory cells or microabscesses were observed in the ALA injection group. There was no significant difference in levels of alanine aminotransferase, aspartate aminotransferase, creatinine or urea nitrogen among the 4 groups (all P > 0.05) . Conclusion:PDT with intralesional injection of ALA is more effective for the treatment of acneiform inflammatory nodules in rat models than PDT with topical application of ALA.
