The development, progression, and curative efficacy of head and neck squamous cell carcinoma (HNSCC) are influenced by complex interactions between epithelial and immune cells. Nevertheless, the specific changes in the nature of these interactions and their underlying molecular mechanisms in HNSCC are not yet fully understood. Cuproptosis, a form of programmed cell death that is dependent on copper, has been implicated in cancer pathogenesis. However, the understanding of cuproptosis in the context of HNSCC remains limited. In this study, we have discovered that cuproptosis-related long non-coding RNAs (CRLs) known as JPX play a role in promoting the expression of the oncogene urokinase-type plasminogen activator (PLAU) by competitively binding to miR-193b-3p in HNSCC. The increased activity of the JPX/miR-193b-3p/PLAU axis in malignant epithelial cells leads to enhanced cell proliferation, migration, and invasion in HNSCC. Moreover, the overexpression of PLAU in tumor epithelial cells facilitates its interaction with the receptor PLAUR, predominantly expressed on macrophages, thereby influencing the abnormal epithelial-immune interactome in HNSCC. Notably, the JPX inhibitor Axitinib and the PLAU inhibitor Palbociclib may not only exert their effects on the JPX/miR-193b-3p/PLAU axis that impacts the malignant tumor behaviors and the epithelial-immune cell interactions but also exhibit synergistic effects in terms of suppressing tumor cell growth and arresting cell cycle by targeting epidermal growth factor receptor (EGFR) and cyclin-dependent kinase (CDK4/6) for the treatment of HNSCC.

Monoclonal gammopathy of undetermined significance combined with renal damage is named monoclonal gammopathy of renal significance.There are few reports about IgA vasculitis in patients with monoclonal gammopathy of undetermined significance.Here,we report a case of monoclonal gammopathy of renal significance,who had manifestations of IgA vasculitis,including purpura,gastrointestinal bleeding and joint pain.The patient had elevated serum creatinine levels,prompting further investigation through immunofixation electrophoresis and bone marrow aspiration biopsy.Immunofixation electrophoresis showed IgA-λ-type monoclonal immunoglobulin,while the bone marrow aspiration biopsy suggested plas-macytosis.Kidney biopsy indicated membranous hyperplastic glomerulonephritis,light and heavy chain deposition,IgA-λ.The patient was diagnosed with monoclonal gammopathy of renal significance.In light of the elevated serum creatinine,the patient was treated with chemotherapy regimen(bortezomib+cy-clophosphamide+dexamethasone).After chemotherapy,there was no significant improvement in the patient's renal function.Subsequently,the patient experienced abdominal pain,skin purpura,joint pain and severe gastrointestinal bleeding.Gastroenteroscopy did not find the exact bleeding position.Angiography revealed hyperplasia of left jejunal artery.Surgical operation found that the bleeding site was located between the jejunum and ileum,where scattered hemorrhagic spots and multiple ulcers were present on the surface of the small intestine,with the deepest ulcers reaching the serosal layer.And the damaged intestine was removed during the operation.Intestinal pathology showed multiple intestinal submu-cosal arteritis,rusulting in intestinal wall necrosis and multiple ulcers.Considering intestinal lesions as gastrointestinal involvement of IgA vasculitis,methylprednisolone was used continually after the opera-tion,and the patient's condition was improved.However,after half a year,the patient suffered a severe respiratory infection and experienced a recurrence of serious gastrointestinal bleeding.It was considered that the infection triggered the activity of IgA vasculitis,accompanied by gastrointestinal involvement.Fi-nally,the patient died from gastrointestinal bleeding.The present case represented a patient with mono-clonal gammopathy of renal significance and IgA vasculitis,prominently presenting with renal insufficien-cy and severe gastrointestinal bleeding,making the diagnosis and treatment process complex.Patients with IgA monoclonal gammopathy who presented with abdominal pain,purpura,and arthralgia should be vigilant for the possibility of concomitant IgA vasculitis.The treatment of cases with IgA vasculitis com-bined with monoclonal gammopathy of renal significance was rather challenging.Plasma cell targeting therapy might be an effective regimen for IgA vasculitis with monoclonal gammopathy.However,patients with poor renal response to the treatment indicated poor prognosis.

Objective : To investigate the effects of gestational diabetes mellitus (GDM) on birth outcome and umbilical artery (UA) blood flow parameters in the third trimester, and to analyze the role of UA blood flow parameters in GDM and birth outcome. Methods : Based on the birth cohort from Wuhu , Anhui , China , 189 pregnant women with GDM were collected as the case group. The non⁃GDM pregnant women were matched 1 ∶ 1 according to age and pre⁃pregnancy body mass index , and 189 normal pregnant women were selected as the control group. Pregnant women with GDM were divided into poorly controlled group and well controlled group according to fasting blood glucose in the third trimester. The UA blood flow parameters and fetal birth outcomes in the third trimester were tracked. Results : Compared with the control group , UA parameters in poorly controlled and well controlled groups significantly increased (F = 6. 63 , P < 0. 05 ; F = 4. 43 , P < 0. 05 ; F = 5. 57 , P < 0. 05) . Poor glycemic control of GDM was associated with increased birth weight and risk of larger than gestational age. The multi⁃factor linear regression model showed that the Z score of the peak systolic velocity/end diastolic velocity (S/D) in the poorly controlled group was negatively correlated with birth weight (β = - 209. 78 , 95% CI: - 301. 48 - 118. 07) . S/D index Z score mediated the relationship between poor blood glucose control and birth weight. The intermediate effect value was - 58. 41 (95% CI: - 106. 40 ~ - 19. 65) , accounting for 25. 98% of the total effect. Conclusion Poor glycemic control in GDM is a risk factor for fetal weight gain , and UA function plays a partial mediating role in influencing neonatal birth weight. GDM pregnant women should strictly control blood glucose level to better protect maternal and infant health.

The above indicators in patients admitted in 2011?2021 were 140, 147, (261±82)minutes, (3±1)days, 233, 54, 198, 89, respectively. There were significant differences in the above indicators between patients admitted in 2000?2010 and 2011?2021 ( χ2=49.04, t=2.24, 7.53, χ2=17.56, 26.02, P<0.05). There was no death in the 346 patients. (3) Analysis of prognosis of patients with synchro-nous colorectal liver metastasis in 2000?2010 and 2011?2021. Of the 346 patients, 295 cases were followed up for 47(range, 1?108)months. Of the 29 patients admitted in 2000?2010 who were followed up, there were 27 cases died. The median survival time, 1-, 3-, 5-year overall survival rates, 1-, 3-, 5-year disease free survival rates of patients admitted in 2000?2010 were 18.0 months (95% confidence interval as 12.7?23.3 months), 82.8%, 11.5%, 3.8%, 53.6%, 8.3%, 4.2%, respec-tively. Of the 266 patients admitted in 2011?2021 who were followed up, there were 109 cases died. The median survival time, 1-, 3-, 5-year overall survival rates, 1-, 3-, 5-year disease free survival rates of patients admitted in 2011?2021 were 54.0 months (95% confidence interval as 38.1?70.4 months), 93.3%, 61.8%, 47.0%, 68.2%, 33.7%, 28.3%, respectively. There were significant differences in overall survival rate and disease free survival rate between patients admitted in 2000?2010 and 2011?2021 ( χ2=47.57, 9.17, P<0.05). Conclusions:With the increase of the operation volume of simultaneous resection of synchronous colorectal liver metastasis, the operation time, time to postoperative initial liquid food intake, postoperative duration of hospital stay and postoperative complications have significantly decreased, while the overall survival rate and disease free survival rate have significantly increased.

Objective : To investigate the correlation between nocturnal sleep duration combined with snoring in the first trimester of pregnancyand small for gestational age(SGA) ，large for gestational age(LGA) ． Methods : Multi- variate Logistic regression model was used to analyze the association between nocturnal sleep duration ，snoring， their combined effects and SGA，LGA. Results : Compared to nocturnal sleep duration 7 to 9 h in the first trimester of pregnancy，sleep duration＜7 h was positively correlated with SGA in male newborn( OR = 4. 22，95% CI : 1. 69 - 10. 52) ; After stratified by snoring，the sleep duration of snoring women＜7 h was positively correlated with SGA ( OR = 5. 68，95% CI : 1. 02－31. 51) ，and the sleep duration of non-snoring women＜7 h was positively correlated with LGA ( OR = 2. 10，95% CI : 1. 16 －3. 81) ． Conclusion Sleep duration＜7 h in the first trimester of preg- nancy is a risk factor for SGA and LGA，and snoring may enhance the association between sleep duration＜7 h in the first trimester of pregnancy and SGA．Pregnant women should keep adequate nocturnal sleep duration to reduce the risk of abnormal neonatal weight.

Objective:To analyze the risk factors for lymph node metastasis in breast cancer patients with axillary lymph node metastasis after neoadjuvant chemotherapy.Methods:The data of 94 female patients with invasive breast cancer in Dongguan People′s Hospital of Guangdong Province from January 2017 to December 2019 were retrospectively analyzed.All patients planned to receive 4-8 cycles of neoadjuvant chemotherapy.After chemotherapy, modified radical mastectomy was performed.Estrogen receptor(ER), progesterone receptor(PR) and human epidermal growth factor receptor 2(HER-2) appeared for the first time in Chinese and English abstracts and texts positive patients received endocrine or targeted therapy.The rest patients received 2-4 cycles of adjuvant chemotherapy or radiotherapy according to the situation.Lymph node metastasis after neoadjuvant chemotherapy was analyzed.The relationship between lymph node metastasis after neoadjuvant chemotherapy and clinicopathological features was analyzed.Risk factors for lymph node metastasis after neoadjuvant chemotherapy were analyzed by Logistic regression.Results:After neoadjuvant chemotherapy, the positive rate of axillary lymph node was 74.47%(70/94). The number of positive axillary lymph nodes, ER status, HER-2 status and cell proliferation-associated human nuclear antigen(Ki67), the completion of chemotherapy cycle, the pathological remission of axillary lymph nodes after chemotherapy and the T stage of tumor after neoadjuvant chemotherapy were associated with lymph node metastasis in patients with positive axillary lymph nodes after neoadjuvant chemotherapy(χ 2=30.053, 10.233, 6.303, 7.666, 18.162, 10.148, 12.418; all P<0.05). More than 3 positive axillary lymph nodes( OR=2.788, 95% CI 1.253-5.318), ER positive( OR=3.298, 95% CI 1.744-7.837), Ki67 positive( OR=2.469, 95% CI 1.184-4.301)and pathological pPR( OR=4.197, 95% CI 2.168-13.788) were independent risk factors for lymph node metastasis after neoadjuvant chemotherapy(all P<0.05). Conclusion:Axillary lymph node-positive breast cancer patients have a high positive rate of axillary lymph nodes after neoadjuvant chemotherapy.More than 3 positive axillary lymph nodes before operation, ER positive, Ki67 positive, and axillary lymph node pPR after neoadjuvant chemotherapy are independent risk factors for lymph node metastasis after neoadjuvant chemotherapy.

Objective:To investigate effects of implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis on breast reconstruction after early breast cancer surgery.Methods:A total of 62 patients with early breast cancer undergoing breast reconstruction in Dongguan People's Hospital of Guangdong Province from July 2017 to December 2019 were selected and randomly divided into two groups, 31 cases in each group. The control group was treated with pectoralis major fascia covering prosthesis for breast reconstruction, and the observation group was treated with pectoralis major fascia combined with serratus anterior fatty fascia flap covering prosthesis for breast reconstruction. The clinical data of the two groups were recorded, the postoperative aesthetic appearance of breast was evaluated. According to the function assessment of cancer therapy-breast cancer (FACT-B) was used to evaluate the score of quality of life before and after operation, and postoperative complications were also observed.Results:In the control group and the observation group, the intraoperative blood loss was (82.61±12.38) ml, (88.76±13.57) ml, respectively; and drainage tube extubation time was (3.51±0.62) d and (3.64±0.58) d, respectively; there was no statistically significant difference between the two groups ( t value was 1.864, 0.853, respectively, all P > 0.05). The operation time of the observation group was longer than that of the control group [(2.59±0.29) h vs. (1.72±0.32) h, t = 11.217, P < 0.001]. The amount of drainage of the control group was higher than that of the observation group [(215.45±47.69) ml vs. (151.36±31.67) ml, t = 6.233, P < 0.001]; the length of hospital stay of the control group was longer than that of the observation group [(14.51±2.32) d vs. (10.79±1.86) d, t = 6.965, P < 0.001]. The excellent and good rate of postoperative breast appearance of the observation group was higher than that of the control group [96.77% (30/31) vs. 74.19% (23/31), χ 2adjusted=4.679, P = 0.031]. There were no statistical differences in all items including health, emotion, function, society/family and other conditions scores of FACT-B and total scores in both groups before the operation (all P > 0.05); all items scores and total scores of both groups after the operation were higher than those before the operation (all P < 0.001), and the sores after the operation of the observation group were higher than those of the control group (all P < 0.001). The total incidence of postoperative complications was 6.45% (2/31) of the observation group, 22.58% (7/31) of the control group, and the difference was not statistically significant (χ 2adjusted=2.080, P = 0.149). Conclusion:Breast reconstruction with implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis after early breast cancer surgery can shorten the postoperative hospital stay, improve the aesthetic appearance of breast, improve the long-term quality of life, and has a high safety.
