OBJECTIVE To investigate the relationship of long non-coding RNA （LncRNA） metastasis-associated lung adenocarcinoma transcript 1 （MALAT1） and doxorubicin （DOX） resistance in osteosarcoma （OS） cells. METHODS MG-63 and MG-63/DOX cells were treated with different concentrations of DOX （0， 0.01， 0.05， 0.1， 1 μmol/L）， and survival rates and half maximal inhibitory concentration were determined using CCK-8 assay. The expressions of LncRNA MALAT1 in MG-63 and MG-63/ DOX cells were detected by real-time quantitative fluorescence PCR. MG-63/DOX cells were divided into Control group， knocking down LncRNA MALAT1 negative control （sh-NC） group， sh-MALAT1 group， sh-MALAT1+anti-NC group， and sh-MALAT1+ anti-miR-154-5p group. The expressions of LncRNA MALAT1， miR-154-5p and cyclin D1 （CCND1） mRNA in MG-63/DOX cells of each group were detected. The effects of knocking down LncRNA MALAT1 on the proliferation， migration， invasion， and apoptosis of MG-63/DOX cells were detected by CCK-8 assay， scratch test， Transwell experiment and flow cytometry， respectively. The expression of proliferating cell nuclear protein （PCNA） and CCND1 protein in MG-63/DOX cells was detected by Western blot assay. Interactions between LncRNA MALAT1 and miR-154-5p， miR-154-5p and CCND1 were detected by dual luciferase reporter gene experiment. RESULTS Compared with 0 μmol/L DOX， 0.01， 0.05， 0.1 and 1 μmol/L DOX could reduce the survival rates of MG-63 and MG-63/DOX cells （except for 0.01 μmol/L DOX） （P＜0.05）， IC50 were 0.07 and 0.13 μmol/L， respectively. The survival rate， cell migration number and invasion number of MG-63/DOX cells， scratch closure rate， mRNA expressions of LncRNA MALAT1， mRNA and protein expressions of CCND1， and PCNA protein expression in sh-MALAT1 group were significantly lower than sh-NC group and Control group； the apoptosis rate and miR-154-5p expression were significantly higher than sh-NC group and Control group （P＜0.05）. sh-MALAT1+anti-miR-154-5p group was able to reverse the aforementioned biological effects in sh-MALAT1 group （P＜0.05）. In MG-63/DOX cells transfected with both MALAT1-wild type （WT） and CCND1-WT， the luciferase activity in the miR-154-5p mimic group was significantly lower than mimic negative control group （P＜ 0.05）. CONCLUSIONS Knocking down LncRNA MALAT1 can inhibit the DOX resistance of OS cells， and its mechanism may be targeting the miR-154-5p/CCND1 axis.

Objective To analyze the changing trends of the incidence and onset age of cervical cancer in Jiangsu Province by using cancer registration data from 2009 to 2019. Methods The information of national cancer registries with continuous data from 2009 to 2019 was selected, and the quality control indices of cancer registration must be up to standards. A total of 16 registries were included in this study. Statistical analysis indicators include the crude incidence rate of cervical cancer, age-standardized incidence rate, actual average onset age, age-standardized average onset age, and average annual percentage change (AAPC). A birth cohort model was constructed to analyze the incidence of cervical cancer among women born from 2009 to 2019 and its incidence trend. Results From 2009 to 2019, the crude and age-standardized incidence rates of cervical cancer among women in Jiangsu Province showed upward trends, with AAPCs of 5.62% (95%CI: 3.47−7.82) and 4.14% (95%CI: 2.06−6.27), respectively. The incidence rate of cervical cancer in rural areas (AAPC=4.46, 95%CI: 1.13−7.91) increased more than that in urban areas (AAPC=3.83, 95%CI: 2.81−4.86). The actual average onset age of cervical cancer increased from 51.53 years in 2009 to 55.07 years in 2019 (β=0.36, P<0.05). The age-standardized average onset age increased from 48.89 years in 2009 to 50.43 years in 2019 (β=0.21, P<0.05). The age composition ratios of cervical cancer in the age group of 60 years and older were 31.90% in 2019 and 22.40% in 2009 (β=3.66, P<0.05). The incidence of cervical cancer in the same age group of people with different birth years showed an upward trend with the increase in birth year. Conclusion From 2009 to 2019, the incidence rate of cervical cancer in Jiangsu Province showed an upward trend, and this trend was more obvious in rural areas than in urban areas. In addition, the average onset age of cervical cancer showed an upward trend.

ObjectiveTo observe the therapeutic effects of Qishao Huoxue prescription on patients with lumbar disc herniation due to Qi stagnation and blood stasis and the effects of this prescription on hemorheological parameters and serum levels of inflammatory mediators. MethodA total of 86 patients with lumbar disc herniation due to Qi stagnation and blood stasis treated in the Wangjing Hospital of China Academy of Chinese Medical Sciences from January 2023 to February 2024 were selected and assigned according to the random number table into observation and control groups （n=43）. Patients in both groups received lumbar traction treatment. In addition， the observation group was orally treated with Qishao Huoxue prescription and the control group with celebrex for 3 weeks. The visual analogue scale （VAS） score， Oswestry disabilitiy index （ODI） score， 12-item Short-Form Survey （SF-12） score， traditional Chinese medicine （TCM） symptom score， hemorheological parameters ［whole blood high shear viscosity， middle shear viscosity， low shear viscosity， plasma viscosity （PV）， and fibrinogen （FIB）］， and the serum levels of inflammatory mediators ［tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and transforming growth factor-β₁ （TGF-β₁）］ were determined before and after treatment. In addition， the clinical efficacy and adverse reactions were observed and compared between the two groups. ResultAfter treatment， both groups showed declined VAS， ODI， and TCM symptom scores （P<0.05）， increased SF-12 physical component summary （PCS） and mental component summary （MCS） scores （P<0.05）. After treatment， the whole blood high shear viscosity， middle shear viscosity， low shear viscosity， PV， and FIB decreased in the observation group （P<0.05）， while they did not show significant variations in the control group. After treatment， both groups of patients showed reductions in TNF-α， IL-6， and IL-1β levels and an elevation in the TGF-β₁ level （P<0.05）. Compared with the control group after treatment， the observation group showed decreases in VAS， ODI， TCM symptom scores and main symptom scores （P<0.05）， no significant differences in the secondary symptom scores， increased PCS and MCS scores （P<0.05）. The observation group outperformed the control group in terms of recovering whole blood high shear viscosity， middle shear viscosity， low shear viscosity， PV， FIB， TNF-α， IL-6， IL-1β， and TGF-β₁ （P<0.05）. The total response rate in the observation group was 97.5% （40/41）， which was higher than that （88.1%， 37/42） in the control group （P<0.05）. No serious adverse reaction was observed in the two groups during the observation period. One case in the observation group showed subcutaneous bruising on the lower limbs， which gradually disappeared after withdrawal. ConclusionQishao Huoxue prescription demonstrated definite effect in treating lumbar disc herniation due to qi stagnation and blood stasis by recovering hemorheological parameters and inhibiting the expression of inflammatory mediators in the serum without inducing adverse reactions. It is worth applying in clinical practice.

Ying and wei qi is derived from the essence of water and grain， and is the basic material to maintain the normal life activities of the body. Ying and wei qi has the difference of nature of yin and yang or the clear and the turbid. When the relationship between ying and wei qi is out of order and in reverse disorder， it will lead to the occurrence of various diseases. Based on the analysis of the theory of "ying-wei disorder" in The Inner Canon of Yellow Emperor （《黄帝内经》）， this paper started from the perspective of the exuberance and debilitation， circulation and function of ying qi and wei qi， focused on the theoretical understanding that the change of deficiency and excess （"fall"） and the change of circulation （"move"）， and refined the core mechanism of "ying-wei disorder"， which is the depletion of ying qi and wei qi， stagnation of ying qi and wei qi， and disharmony of ying qi and wei qi， and finally summarized the syndrome identification and treatment method of supporting ying qi and assisting wei qi， promoting ying qi and moving wei qi， regulating ying qi and wei qi， and constructed the syndrome identification and treatment system for ying-wei disorder of malignant tumor in clinic.

For patients with partial jaw defects, cysts and dental implants, doctors need to take panoramic X-ray films or manually draw dental arch lines to generate Panorama images in order to observe their complete dentition information during oral diagnosis. In order to solve the problems of additional burden for patients to take panoramic X-ray films and time-consuming issue for doctors to manually segment dental arch lines, this paper proposes an automatic panorama reconstruction method based on cone beam computerized tomography (CBCT). The V-network (VNet) is used to pre-segment the teeth and the background to generate the corresponding binary image, and then the Bezier curve is used to define the best dental arch curve to generate the oral panorama. In addition, this research also addressed the issues of mistakenly recognizing the teeth and jaws as dental arches, incomplete coverage of the dental arch area by the generated dental arch lines, and low robustness, providing intelligent methods for dental diagnosis and improve the work efficiency of doctors.

Objective: To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. Methods: According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. Results: The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. Conclusion This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

We aimed to study the articles and applied prescriptions of Moutan Cortex in Synopsis of theGolden Chamber, summarize and analyze its laws on the disease location and disease nature, and analyze its compatibility, dosage and processing laws. Based on the knowledge of Moutan Cortex by Zhongjing, we found that the kidney, bladder, uterus and intestine involved in Zhongjing's application of peony bark prescription, which belongs to the disease of "lower abdomen" in Huangdi Nei Jing. And the prescription of Moutan Cortex mainly focused on the syndromes of "depression" and "blood stasis", which are characterised by five kinds: water depression, dampness depression, stasis-heat, blood stasis and ecchymosis. and the compatibility rule of Zhongjing application of Moutan Cortex is analyzed accordingly. In addition, the study found that as the downward movement of the disease position, the amount of Moutan Cortex increased, and the processing of the problem followed the principle of "if disease is slow onset, the Moutan Cortex heart should be removed, but if disease is acute, Moutan Cortex heart should be kept". Finally, we combined modern clinical application of Moutan Cortex with modern pharmacological research, in order to expand the scope of clinical application of Moutan Cortex and "the same treatment of different diseases" to provide theoretical guidance.

Objective:To investigate the epidemiological characteristics of COVID-19 caused by 2019-nCoV Delta variant in Shangyu district, Shaoxing of Zhejiang province in 2021, and provide evidence for the improvement of COVID-19 control and prevention measures.Methods:The incidence data of COVID-19 in Shangyu from December 7 to 21, 2021 was obtained from Shangyu District Center for Disease Control and Prevention. The epidemiological characteristics of the cases, i.e. the population, time and space distributions, were analyzed, and the incubation period and time-varying reproduction numbers ( R t) were calculated. Results:From December 7 to 21, 2021, a total of 380 COVID-19 cases caused by 2019-nCoV Delta variant were detected in Shangyu, the median age of the cases was 52 years, M ( Q1，Q3: 38, 61). The male to female ratio of the cases was 1∶1.25, and the cases were mainly workers (36.58%) and farmers (27.63%). The epidemic affected 9 townships (or community) of Shangyu, especially Caoe and Baiguan communities with the cases accounting for 57.10% and 31.53% respectively. The median incubation period of cases was 4.00 days, M ( Q1，Q3: 3.00, 5.75). The basic reproduction number ( R0) was 4.06, and the R t was 5.62 in early phase of the outbreak (the highest) and continuously decreased to less than 1.00 within 10 days after the detection of the outbreak. The number of COVID-19 cases decreased to 0 within 14 days after the outbreak (December 7-21), and the main detection methods were screening in centralized isolation (55.53%) and home isolation (40.00%). The infection rates of close contacts and secondary close contacts were 2.06% and 0.46% respectively. Conclusion:The epidemic of COVID-19 in Shangyu characterized by short incubation period, large number of infected people, and case clustering, suggesting the strong transmission of Delta variant (B.1.617.2). Comprehensive prevention and control measures, such as management of close contacts and secondary close contacts, and high-risk area, are essential for the rapid control of the epidemic.
