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.

Purpose To explore the clinical value of screening for partial agenesis of the corpus callosum(PACC)via measuring the distance from the end of the fetal corpus callosum to the occipital bone.Materials and Methods A Prospective study were performed from October 2017 to April 2023 in Ji’an Maternal and Child Health Care Hospital and Jiangxi Maternal and Child Health Hospital.A total of 33 PACC fetuses(abnormal group)and 396 normal fetuses(normal group)were selected as the research subjects.The distance(Z value)from the terminal posterior edge of the corpus callosum to the occipital bone was measured,Z value was calculated and compared between groups.The truncation value and related diagnostic efficiency indexes were calculated by receiver operator characteristic curve analysis,and the positive rate of Z value of abnormal group was compared with that of indirect signs.Results The distance from the terminal posterior edge of the corpus callosum to the occipital bone was positively correlated with the gestational age(r=0.913,P<0.001).The best regression equation was that the distance from the terminal posterior edge of the corpus callosum to the occipital bone was 3.879+1.115×gestational age,and the standard deviation was 1.670.The results of mean comparison showed that the Z value of the abnormal group was significantly higher than that of the normal group(t=11.223 9,P<0.001).When Z value 2.199 7 was used as the cut-off value for the diagnosis of PACC,the area under the curve was 0.9981,the Yoden index was 0.959 6,and the sensitivity,specificity,positive and negative predictive values were 96.97%,98.99%,88.89%and 99.75%,respectively.The positive rate of Z value in abnormal group was significantly higher than that of indirect signs(96.97%vs.63.64%,χ2=7.692 3,P<0.01).Conclusion The distance from the terminal posterior edge of corpus callosum to the occipital bone of PACC fetus is larger than that of normal fetus.The increase of Z value indicates that the end of corpus callosum moves forward,which can be used as one of the basis for screening PACC,and it has high clinical value when Z value 2.199 7 is used as the cut-off value for PACC screening.

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 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.
