Objective To investigate the relationship between thyroid nodules with calcification and thyroid carcinoma and its significance in the screening of thyroid carcinoma in high risk group.Methods The clinical data of 1771 patient undergoing surgery for thyroid nodules from March, 2006 to March, 2009 in Huashan Hospital, Fudan University were retrospectively analyzed. Results Among 1771 patients, 500 were finally identified as having malignant tumors. Incidence of calcification in thyroid carcinoma was 68. 4%, and that in benign thyroid nodules was 27.0% ( χ2 = 259. 5, P < 0. 05 ). The specificity of microcalcification for the diagnosis of carcinoma was 89. 4%, and its positive predictive value was 66. 3% ( χ2 = 368.6, P < 0. 01 ). The incidence of thyroid carcinoma in patients < 45 years was 39.2%, while that in patients ≥ 45 years was 22.9% ( χ2 = 51.12, P < 0. 05 ). The incidence of carcinoma in patients of single thyroid nodule was 31.7% and that in those with multiple nodules was 26. 4% (χ2 =4. 766,P < 0. 05). Metastasis was pathologically diagnosed in 26. 8% of lymph nodes found by preoperative ultrasonography. Conclusions The specificity of thyroid nodule calcification, especially microcalcification is high for the diagnosis of thyroid carcinoma. High-risk index for carcinoma includes thyroid nodules with microcalcification, < 45 years old and single thyroid nodule.

ObjectiveTo analyze and summarize the medication rules of different Pinelliae Rhizoma processed products in the syndrome differentiation and treatment of insomnia using data mining. MethodThe literature on the treatment of insomnia with Pinelliae Rhizoma was retrieved from the China National Knowledge Infrastructure (CNKI), VIP, and PubMed databases over the past 10 years. An Excel database was constructed to record the prescriptions of different Pinelliae Rhizoma processed products in the treatment of insomnia. SPSS 26.0 software was used for frequency analysis of traditional Chinese medicine (TCM) syndromes related to insomnia, compatibility of drugs, drug effects, and properties. SPSS 26.0 was also used for cluster analysis, factor analysis, and IBM Modeler 18.0 plugin for association rule analysis of the core compatibility of different Pinelliae Rhizoma processed products and combinations. ResultAfter applying inclusion and exclusion criteria, 125 relevant articles were finally included. The commonly used processed products of Pinelliae Rhizoma in the treatment of insomnia were Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, and Pinelliae Rhizoma Praeparatum cum Alumine. Among them, Pinelliae Rhizoma Praeparatum was the most frequently used. All three processed products of Pinelliae Rhizoma were often used for insomnia with such TCM syndromes as phlegm-heat disturbing the heart, phlegm-dampness obstructing the interior, and liver Qi stagnation. The compatible drugs were sweet, bitter, and pungent in flavor, cold in nature, and acted on the lung, spleen, heart, and liver meridians, with functions of nourishing deficiency, clearing heat, and calming the mind. The common prescriptions used were Wendantang, Chaihu Longgu Mulitang, Banxia Xiexintang, and Xiaochaihutang, with doses ranging from 6 to 30 g. The core drug combinations were Pinelliae Rhizoma Praeparatum-Poria-Ziziphi Spinosae Semen, Pinelliae Rhizoma Praeparatum Cum Zingibere et Alumine-Jujubae Fructus-Codonopsis Radix, and Pinelliae Rhizoma Praeparatum Cum Alumine-Scutellariae Radix-Bupleuri Radix. ConclusionThis study, for the first time, analyzed and summarized the compatibility and prescription application rules of commonly used processed products of Pinelliae Rhizoma in the treatment of insomnia from the perspective of TCM syndrome differentiation, which provides a theoretical basis for the rational, safe, and effective use of Pinelliae Rhizoma in the treatment of insomnia in TCM.

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.

Objective:To investigate the uncoupling protein 2 (UCP2) expression and its relations with apoptosis, oxidative stress and mitochondrial division/fusion in HT22 cell model with intracerebral hemorrhage.Methods:HT22 cells cultured in vitro were divided into control group, and groups of 3, 6, 12 and 24 h after modeling; cells in the later 4 groups were given 10 μmol/L hemin for 3, 6, 12 and 24 h, respectively, and cells in the control group were given the same equivalent solvent for 24 h. The apoptosis of HT22 cells in these 5 groups was detected by Annexin V-FITC/propidium iodide Apoptosis Detection Kit. The reactive oxygen species (ROS) expressions in these 5 groups were detected by fluorescence probe method. Western blotting was used to detect the protein expressions of UCP2, apoptosis-related protein cleaved caspase 3, anti-apoptosis protein B cell lymphoma/leukemia2 (bcl2), and mitochondrial division/fusion proteins (Fis1, Drp1, Opa1, and Mfn2). Results:As compared with the control group, groups of 3, 6, 12 and 24 h after modeling had significantly increased apoptosis rate, ROS level, and UCP2, cleaved caspase 3, Fis1 and Drp1 expressions, and statistically decreased bcl2, Opa1, and Mfn2 expressions. Groups of 3, 6, 12 and 24 h after modeling had successively increased apoptosis rate, successively increased ROS levels, and successively increased UCP2, cleaved caspase 3, Fis1 and Drp1 expressions, and successively decreased bcl2, Opa1, and Mfn2 expressions, with significant differences ( P<0.05). Conclusion:UCP2 expresses in HT22 cell model with intracerebral hemorrhage in time-dependent manner, and it has close relations with apoptosis, oxidative stress, and dynamic balance of mitochondrial division/fusion of HT22 cells.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.
