RESUMO
OBJECTIVES: Carotid intima-media thickness (CIMT) is a noninvasive marker of atherosclerosis, a typical pathologic process underlying cardiovascular diseases (CVDs). It is essential to explore the relationships between weight loss and the reduction of CIMT. STUDY DESIGN: This was an updated systematic review and meta-analysis. METHODS: A systematic literature search was conducted to collect relevant clinical trials. The pooled results of meta-analyses were assessed by weighted mean difference (WMD) and the corresponding 95 % confidence interval (95% CI). RESULTS: Thirty-three articles involving 2273 participants were collected in this meta-analysis. Among all participants with obesity, the pooled mean of weight loss was -23.26 kg (95% CI: -27.71 to -18.81), and the pooled mean change of CIMT was -0.06 mm (95% CI: -0.08 to -0.04). Compared with Non-surgical interventions, Surgical ones could lead to much higher weight loss (Pbetween groups < 0.001). A more significant CIMT reduction was identified among Surgical intervention patients than among Non-surgical intervention participants (Pbetween groups < 0.001). CONCLUSIONS: Effective interventions, especially Surgical interventions, could reduce the weight of patients with obesity, followed by the decline of CIMT, which might further disturb atherosclerosis progression and lower CVD risk.

Objective: To investigate the effects of lncRNA SNHG11 on proliferation, migration, invasion and apoptosis of colorectal cancer cancer cells and possible mechanisms. Methods: qRT-PCR was performed to detect the expression level of lncRNA SNHG11 in colorectal cancer tissues and its related cell lines. The correlation between SNHG11 expression and clinical prognosis of patients was assessed by bioinformatics techniques. Cultured CRC cell lines were transfected with shCtrl (shCtrl group), shSNHG11#1 (shSNHG11#1 group), shSNHG11#2 (shSNHG11#2 group), Control cDNA (Control cDNA group), and SNHG11 cDNA (SNHG11 cDNA), respectively. Thiazolyl blue (MTT), clone formation assay, Transwell assay, cell scratch assay, and flow cytometry were used to detect the proliferation, migration, invasion, and apoptosis of CRC cells in each group. Western protein blotting was used to detect the expression of relevant proteins in each group, and the effect of lncRNA SNHG11 knockdown on the growth of tumour cells in vivo was analysed by nude mice tumouring assay. Phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signalling pathway inhibitor LY294002 was used for rescue experiments. Results: The expression of lncRNA SNHG11 was significantly higher in colorectal cancer cells and tissues than in normal tissues (P<0.05). Survival analysis showed that the expression level of SNHG11 was not statistically associated with CRC survival (P>0.05). shSNHG11#2 group compared with shCtrl group. MTT OD490/570 values decreased, the number of CRC cell clones decreased, the number of Transwell cells decreased, the area of cell scratch decreased, and the apoptosis rate increased (P<0.05). The mesenchymal markers matrix metalloproteinase (MMP9), N-cadherin and vimentin were significantly reduced, and the expression of the epithelial marker E-cadherin was upregulated. The expression of anti-apoptotic proteins Bcl-2 and Bcl-xl was decreased, and the expression of pro-apoptotic protein Bax was increased (P<0.05).In vivo experiments showed that lncRNA SNHG11 knockdown inhibited the growth of colorectal cancer cells, and the expression of Ki67 was reduced in tumours (P<0.05). LncRNA SNHG11 knockdown inhibited the expression of p-PI3K, p-Akt and p-mTOR.The PI3K/Akt/mTOR signaling pathway inhibitor LY294002 was able to restore the malignant cytological progression of colorectal cancer cells induced by the overexpression of lncRNA SNHG11. Conclusions: LncRNA SNHG11 is highly expressed in colorectal cancer. lncRNA SNHG11 can promote the malignant progression of colorectal cancer cells by regulating the PI3K/Akt/mTOR signaling pathway, and this finding provides a new theoretical basis for targeted therapy of colorectal cancer.

Objective: To investigate the efficacy and safety of bupivacaine liposome for pericapsular nerve group block (PENGB) for postoperative analgesia in elderly patients with total hip replacement. Methods: A total of 42 elderly patients underwent total hip replacement were selected in the Second Affiliated Hospital of Wenzhou Medical University from May to July in 2023, including 19 males and 23 females, aged (68.8±6.3) years, the American Society of Anesthesiologists (ASA) grade â to â ¢. They were divided into bupivacaine liposome group (observation group) and levobupivacaine hydrochloride group (control group) according to random number table, with 21 cases in each group. All the patients were anesthetized by lumbar anesthesia combined with PENGB. During PENGB, the observation group was injected with 10 ml (133 mg) bupivacaine liposome+5 ml normal saline, and the control group was injected with 10 ml (75 mg) levobupivacaine hydrochloride+5 ml normal saline. The primary outcome measures included the rest and movement visual analogue scale (VAS) scores at 6, 12, 24, 36, 48, 60, and 72 h after operation, the sufentanil consumption in analgesic pump, the numbers of analgesic pump compressions, and the rates of additional parexib sodium use in ward. The secondary outcome measures were the changes in lower limb muscle strength, the length of hospital stay and the occurrence of adverse reactions. Results: There was no significant difference in the rest and movement VAS scores between the two groups at pre-operation and at 6 h after operation (P>0.05);but the rest and movement VAS scores at 12, 24, 36, 48, 60 and 72 h after operation in observation group were significantly lower than those in control group (P<0.05); the rest and movement VAS scores at 6, 12, 24, 36, 48, 60 and 72 h after operation were lower than those at pre-operation in two group (P<0.05). The consumption of sufentanil in analgesic pump and parexib sodium usage in observation group were lower than those in control group at 12, 24, 36 and 48 h after operation (P<0.05). The total number of analgesic pump compressions, the number of effective compressions and the number of ineffective compressions in 48 h in observation group were lower than those in control group (P<0.05). The muscle strength of the lower limbs of all patients were able to move against gravity at 12 h after operation. The incidence of nausea in 48 h after operation in observation group was 9.5% (2/21), which was lower than 42.9% (9/21) in control group (P=0.014). No postoperative vomiting occurred in all patients. The length of the hospital stay was (9.3±2.2) d in observation group and (8.9±1.9) d in control group, and there was no significant difference between the two groups (P=0.500). Conclusion: Compared with levobupivacaine hydrochloride, liposomal bupivacaine in PENGB provides analgesic effects for up to 72 h after total hip replacement in elderly patients, reduces postoperative opioid and other analgesics usage, decreases the incidence of postoperative nausea, and has a minor effect on lower limb movement without prolonging hospitalization.

Objective: To investigate the association between positive anti-thyroid peroxidase antibody (TPOAb) and/or anti-thyroglobulin antibody (TgAb) and the occurrence of thyroid immune-related adverse events (irAEs) in patients with malignant tumors who treated with immune checkpoint inhibitors (ICIs). Methods: A case-control study. A total of 116 patients with malignant tumor who received ICIs treatment and underwent thyroid function evaluation at Peking Union Medical College Hospital from January 2017 to April 2023 were enrolled retrospectively, including 77 males and 39 females, with a median age of (M(Q1, Q3)) 63.0 (55.0, 70.0) years. The patients were divided into the euthyroid group (n=58) and the thyroid irAEs group (n=58) according to whether thyroid irAEs occurred after ICIs treatment. The clinical characteristics and baseline anti-thyroid antibodies associated with the occurrence of thyroid irAEs after ICIs treatment in patients with malignant tumors were evaluated. Variables with statistical significance in univariate analysis were included in multivariate logistic regression model to analyze the risk factors for thyroid irAEs in patients with malignant tumors who received ICIs treatment. Results: In irAEs group, therewore 4 (3.4%) cases of clinical thyrotoxicosis, 23(19.8%) cases of subclinical thyrotoxicosis, 23 (19.8%) cases of clinical hypothyroidism, and 8(6.9%) cases of subclinical hypothyroidism. The positive rate of anti-thyroid antibodies at baseline in the thyrioid irAEs group was higher than that in the euthyroid groupï¼»16/58ï¼27.6%ï¼vs 3/58ï¼5.2%ï¼ï¼P=0.001ï¼½. After at least one course of ICIs treatment, the incidence of thyroid irAEs in patients with positive anti-thyroid antibodies at baseline was 84.2% (16/19), whereas it was 43.3% (42/97) in patients with negative anti-thyroid antibodies(P=0.001). Univariate logistic regression analysis showed that gender (OR=2.812, 95%CI:1.257-6.293), baseline thyroid autoantibodies were positive (OR=6.984, 95%CI: 1.909-25.547), baseline TgAb positivity (OR=8.909, 95%CI: 1.923-41.280), and baseline TPOAb positivity (OR=7.304, 95%CI: 1.555-34.308) were associated with thyroid irAEs (all P<0.05). Multivariate logistic regression analysis indicated that baseline TgAb positivity (OR=7.637, 95%CI: 1.617-36.072) was a risk factor for thyroid irAEs (P=0.01). Conclusions: The incidence of thyroid irAEs is higher in patients who are positive for baseline TPOAb and/or TgAb compared to those who are negative for TPOAb and TgAb. Patients with positive TgAb at baseline are at high risk of developing thyroid irAEs.

Objective: To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021. Methods: A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children. Results: The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M (Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 (χ2trend=111.427, P<0.001). The median of urinary iodine concentration M (Q1, Q3) in children was 182.50 (121.00, 261.00) µg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [M (Q1, Q3): 190.90 (128.80, 269.00) µg/L] was significantly higher than that in children in coastal areas [M (Q1, Q3): 173.00 (113.00, 250.30) µg/L] (P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95%CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95%CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95%CI: 2.64%-3.10%), 588/20 530] (P=0.001). Conclusion: From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

RESUMO
The ninth edition of TNM staging for lung cancer has been announced at the 2023 World Lung Cancer Congress and implemented from January 1, 2024. The focus of the ninth TNM staging change is dividing N2 into N2a and N2b, as well as M1c into M1c1 and M1c2. Although the T staging has not changed, it has played an important role in verifying the eighth edition of the T staging. The subdivision of stage N2 has led some patients with â ¢A of the eighth edition to experience ascending or descending stages, which will more accurately help to assess the condition and prognosis of patients with mediastinal lymph node metastasis, as well as the design of related clinical studies. Modifying the M1c staging will help define oligometastasis and explore new treatment models in the future. The ninth edition of the TNM staging system provides a more detailed division of different tumor loads, but there is no clear explanation for the staging of lung cancer after neoadjuvant therapy. Further data analysis is needed, and it is expected to be answered in the tenth edition of TNM staging.

Objective: To investigate the effect of tocilizumab (TCZ) on ventricular arrhythmias (VAs) after myocardial infarction (MI) in Sprague-Dawley rats and explore its potential mechanism. Methods: The random number table method was used to divide 32 adult male Sprague-Dawley rats into 4 groups: Sham group, TCZ group, MI group and MI+TCZ group, with 8 rats in each group. The MI model was established by ligation of the left anterior descending branch of the coronary artery in the MI and MI+TCZ groups, and only sutured without ligation in the Sham and TCZ groups. TCZ was injected into the left superior cervical ganglion (SCG) of rats in the TCZ and MI+TCZ groups after successful modeling or sham operation, and the same amount of normal saline was injected in the Sham and MI groups. 24 h after successful modeling, ECG of rats in each group was recorded, heart rate variability (HRV, including low frequency power (LF), high frequency power (HF), LF/HF ratio), QT interval, QTc interval were calculated, and left ventricular effective refractory period (ERP) and VA inducibility were measured. Myocardial infarct size and tissue changes were observed with triphenyl tetrazolium chloride staining and HE staining. Real-time PCR analysis was used to detect the messager RNA (mRNA) expression of interleukin-6 (IL-6) and signal transducer and activator of transcription (STAT) 3 in SCG and potassium voltage-gated channel subfamily D member 2 (Kcnd2) in myocardial infarction periphery. The expression of c-fos in SCG was detected by immunofluorescence staining. Results: Compared with Sham group and MI+TCZ group, rats in MI group had higher LF and LF/HF ratio, longer QT interval and QTc interval, more VAs induced, lower HF and shorter ERP (P all<0.05). Triphenyl tetrazolium chloride staining and HE staining showed that rats in the Sham and TCZ groups had normal myocardial tissue structure, those in the MI group had severe myocardial injury, and those in the MI+TCZ group had less myocardial injury than those in the MI group. Real-ime PCR analysis showed that compared with Sham group and MI+TCZ group, mRNA expression levels of IL-6 and STAT3 in SCG of rats in MI group were higher, and mRNA expression level of myocardial Kcnd2 was lower (P all<0.05). Immunofluorescence staining showed that the content of c-fos in SCG of rats in MI group was higher than that of Sham group and MI+TCZ group (P all<0.05). Conclusions: TCZ may reduce neural activity of the SCG after MI by inhibiting the IL-6/STAT3 signaling pathway, thereby alleviating myocardial injury and inhibiting VAs.

Temozolomide resistance is a major cause of recurrence and poor prognosis in neuroglioma. Recently, growing evidence has suggested that mitophagy is involved in drug resistance in various tumor types. However, the role and molecular mechanisms of mitophagy in temozolomide resistance in glioma remain unclear. In this study, mitophagy levels in temozolomide-resistant and -sensitive cell lines were evaluated. The mechanisms underlying the regulation of mitophagy were explored through RNA sequencing, and the roles of differentially expressed genes in mitophagy and temozolomide resistance were investigated. We found that mitophagy promotes temozolomide resistance in glioma. Specifically, small ubiquitin-like modifier specific protease 6 (SENP6) promoted temozolomide resistance in glioma by inducing mitophagy. Protein-protein interactions between SENP6 and the mitophagy executive protein PTEN-induced kinase 1 (PINK1) resulted in a reduction in small ubiquitin-like modifier 2 (SUMO2)ylation of PINK1, thereby enhancing mitophagy. Our study demonstrates that by inducing mitophagy, the interaction of SENP6 with PINK1 promotes temozolomide resistance in glioblastoma. Therefore, targeting SENP6 or directly regulating mitophagy could be a potential and novel therapeutic target for reversing temozolomide resistance in glioma.

Objective: To investigate the effects of preoperative quetiapine on postoperative delirium (POD) and sleep quality in elderly orthopedic patients. Methods: Prospectively, 111 elderly patients, American Society of Anesthesiologists (ASA) grade â ¡-â ¢, scheduled to undergo knee or hip surgery in the Affiliated Huangyan Hospital of Wenzhou Medical University under continuous spinal anesthesia from August 2021 to March 2023, were selected and randomly divided into two groups by random number table: control group (group C, 1 h preoperative placebo) and quetiapine group (group Q, 1 h preoperative quetiapine 12.5 mg). In group C, 54 cases were enrolled, including 25 males and 29 females, with an average age of (73.5±4.9) years. In group Q, 57 cases were enrolled, including 26 males and 31 females, with an average age of (74.8±5.0) years. The primary outcome measures were the incidence of POD evaluated by using confusion assessment method (CAM) at 24, 48, and 72 hours after surgery, and the secondary outcome measures included Pittsburgh sleep quality index (PSQI) scores at 24 and 48 hours after surgery and satisfaction of pain management within 24 hours after surgery. Results: The incidence of POD at 24, 48, and 72 h after surgery in group Q was 5.4% (3/57), 12.5% (7/57), 14.3% (8/57), respectively, while that in group C was 18.2% (10/54), 21.8% (12/54), 21.8% (12/54), respectively. The incidence of POD at 24 h after surgery in group Q was lower than that in group C (P=0.036). There was no significant difference in the incidence of POD at 48 and 72 h after surgery between two groups (all P>0.05). The PSQI score of patients in group Q at 24 and 48 h after surgery were (3.8±1.2) and (6.9±1.1) scores, respectively, which in group C were (10.5±2.8) and (7.3±1.3) scores, respectively. Compared with group C, the PSQI score of patients in group Q at 24 h after surgery was significantly higher (P<0.001), but there was no significant difference at 48 h after surgery (P=0.068). The satisfaction scores of pain management at 24 h after surgery in group Q was (91±7) scores, which was higher than that in group C of (81±6) scores (P<0.001). Conclusion: Oral intake of low-dose quetiapine 1 h preoperatively can reduce the incidence of POD, improve postoperative sleep quality and enhance postoperative satisfaction of pain management at 24 hours after surgery in elderly orthopedic patients undergoing knee or hip surgery.

Objective: To investigate the cytotoxic effects of induced pluripotent stem (iPS) cells of anti-mesothelin (MSLN)-chimeric antigen receptor natural killer (CAR-NK) cells (anti-MSLN-iCAR-NK cells) on ovarian epithelial cancer cells. Methods: Twenty cases of ovarian cancer patients who underwent surgical treatment at Henan Provincial People's Hospital from September 2020 to September 2021 were collected, and 20 cases of normal ovarian tissues resected during the same period due to other benign diseases were also collected. (1) Immunohistochemistry and immunofluorescence were used to verify the expression of MSLN protein in ovarian cancer tissues. (2) Fresh ovarian cancer tissues were extracted and cultured to obtain primary ovarian cancer cells. Recombinant lentiviral vectors targeting anti-MSLN-CAR-CD244 were constructed and co-cultured with iPS cells to obtain anti-MSLN-iCAR cells. These cells were differentiated into anti-MSLN-iCAR-NK cells using cytokine-induced differentiation method. The cell experiments were divided into three groups: anti-MSLN-iCAR-NK cell group, natural killer (NK) cell group, and control group. (3) Flow cytometry and live cell staining experiment were used to detect the apoptosis of ovarian cancer cells in the three groups. (4) Enzyme-linked immunosorbent assay (ELISA) was used to measure the expression levels of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), granzyme B (GZMB), perforin 1 (PRF1), interleukin (IL)-6, and IL-10 in the three groups of ovarian cancer cells. Results: (1) Immunohistochemistry analysis showed that a positive expression rate of MSLN protein in ovarian cancer tissues of 65% (13/20), while normal ovarian tissues had a positive rate of 30% (6/20). The comparison between the two groups was statistically significant (χ2=4.912, P=0.027). Immunofluorescence analysis revealed that the positive expression rate of MSLN protein in ovarian cancer tissues was 70% (14/20), while normal ovarian tissues had a positive rate of 30% (6/20). The comparison between the two groups was statistically significant (χ2=6.400, P=0.011). (2) Flow cytometry analysis showed that the apoptotic rate of ovarian cancer cells in the anti-MSLN-iCAR-NK cell group was (29.27±0.85)%, while in the NK cell group and control group were (8.44±0.34)% and (6.83±0.26)% respectively. There were statistically significant differences in the comparisons between the three groups (all P<0.01). Live cell staining experiment showed that the ratio of dead cells to live cells in the anti-MSLN-iCAR-NK cell group was (36.3±8.3)%, while in the NK cell group and control group were (5.4±1.4)% and (2.0±1.3)% respectively. There were statistically significant differences in the comparisons between the three groups (all P<0.001). (3) ELISA analysis revealed that the expression levels of IFN-γ, TNF-α, GZMB, PRF1, IL-6, and IL-10 in ovarian cancer cells of the anti-MSLN-iCAR-NK cell group were significantly higher than those in the NK cell group and the control group (all P<0.05). Conclusion: The anti-MSLN-iCAR-NK cells exhibit a strong killing ability against ovarian cancer cells, indicating their potential as a novel immunotherapy approach for ovarian cancer.

Objective: To investigate the chronic respiratory symptoms and pulmonary function of adult residents in 3 towns of Hongtong County, Shanxi Province, and to explore their risk factors. Methods: The investigation of chronic respiratory symptoms and lung function status of adult residents in Hongdong County is based on the regional population of the entire county in Hongdong County. The project was initiated by the Science and Technology Department of Linfen City and coordinated by the Hongdong County Government. The investigation will be conducted in 3 townships in Hongdong County, Linfen City, Shanxi Province from April to November 2021: Demographic characteristics, respiratory symptoms, smoking dust exposure and other personal history were collected through questionnaires. Physical examination, routine blood tests and lung function tests were also performed on each individual. SPSS 22.0 software was used to conduct t test, χ2 test, ANOVA or Kruskal-Wallis test for statistical analysis of the collected information. Results: 10 945 subjects aged 18-102 years were included in the analysis, of whom 3 754 (34.3%) were male, 1 222 (11.2%) had a history of dust exposure, 7 164 (65.5%) had used straw and firewood as cooking fuel, and 3 296 (30.1%) had a history of smoking. Among the participants, 394 (3.6%), 339 (3.1%), and 1 543 (14.1%) had respiratory symptoms such as chronic cough, sputum, and dyspnea. Statistics showed that the population with chronic respiratory symptoms was more elderly and had a smoking history, and the incidence of chronic respiratory symptoms was higher in those who smoked more than 40 packs a year (all P<0.05). Men with a history of dust exposure were more likely to suffer from chronic cough and expectoration, while emaciation and biofuel use for more than 40 years were more likely to suffer from chronic expectoration and dyspnea (all P<0.05). The median values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and FEV1/FVC in 1 second were 2.19 L/s, 3.24 L and 69.16%, respectively. Among them, the lung function of 5 801 (53.0%) respondents was lower than the expected value. The median FEV1/FVC decreased with the increase of age. The FEV1/FVC of people over 40 years old with smoking history was lower, the dust exposure history of people with decreased lung function was more than that of people with normal lung function, and the incidence of chronic expectoration and dyspnea was higher in people with decreased lung function (all P<0.05). The absolute value and ratio of eosinophils in patients with decreased ventilation function over 60 years old were significantly higher than those with normal ventilation function, but the level of body mass index (BMI) was lower (all P<0.05). Conclusion: In Hongdong County, Shanxi Province, grassroots residents have poor medical awareness, low lung function examination rate, chronic respiratory symptoms and lung function decline are associated with more risk factors. Primary medical institutions need to formulate prevention strategies and carry out lung function detection according to the actual situation, focusing on monitoring and follow-up of high-risk groups to achieve early and timely prevention, diagnosis and treatment of chronic obstructive pulmonary disease.

OBJECTIVE: To clarify the clinical characteristics of influenza pneumonia in the elderly patients and the relationship between D-dimer and the severity of influenza pneumonia. METHODS: In the study, 52 hospitalized patients older than 65 years with confirmed influenza pneumonia diagnosed in Peking University People's Hospital on 5 consecutive influenza seasons from 2014 were retrospectively analyzed. General information, clinical symptoms, laboratory data, treatment methods and prognosis of the patients were collected. The relationship between D-dimer and pneumonia severity was analyzed, and receiver operating characteristic (ROC) curve was used to evaluate the predictive value of D-dimer. RESULTS: Among the 52 patients, 31 were male (31/52, 59.6%), the average age was (77.1±7.4) years, and 19 of them (36.5%) were diagnosed with severe pneumonia. About 70% patients presenting with fever. In the severe group, the patients were more likely to complain of dyspnea than in the non-severe group (14/19, 73.7% vs. 10/33, 30.3%, P=0.004), severe pneumonia group had higher level of CURB-65 (confusion, urea, respiratory rate, blood pressure, and age>65), pneumonia severity index (PSI), C-reactive protein, urea nitrogen, lactate dehydrogenase, fasting glucose, and D-dimer (P value was 0.004, < 0.001, < 0.001, 0.003, 0.038, 0.018, and < 0.001, respectively), albumin was lower than that in the non-severe group [(35.8±5.6) g/L vs. (38.9±3.5) g/L, t=-2.348, P=0.018]. There was a significant positive correlation between the D-dimer at the first admission and PSI score (r=0.540, 95%CI: 0.302 to 0.714, P < 0.001), while a significant negative correlation with PaO2/FiO2 (r=-0.559, 95%CI: -0.726 to -0.330, P < 0.001). Area under the curve of D-dimer was 0.765 (95%CI: 0.627 to 0.872). Area under the curve of PSI was 0.843 (95%CI: 0.716 to 0.929). There was no statistically significant difference in test efficacy between the two (Z=2.360, P=0.174). D-dimer level over 1 225 µg/L had a positive predict value for influenza pneumonia in hospital death with a sensitivity of 76.92% and a specificity of 74.36%. CONCLUSION: Influenza pneumonia in the elderly always has atypical symptoms, dyspnea is a prominent feature in severe cases, D-dimer level is associated with the severity of influenza pneumonia, and greater than 1 200 µg/L has a good predictive value for in-hospital death in the elderly.

To investigate the feasibility and safety of total laparoscopic cardia function preserving gastrectomy for gastric carcinoma. Clinical data of 10 patients undergoing total laparoscopic cardia function preserving gastrectomy for gastric carcinoma from November 2020 to December 2021 were retrospectively collected. There were 7 males and 3 females. The mean age was (66.1±12.9) years (ranged from 38 to 86 years). All of the 10 patients were successfully performed total laparoscopic cardia function preserving gastrectomy without conversion to laparotomy. The time of digestive tract reconstruction was (24.8±3.3) min (20-30 min), and the intraoperative blood loss was (35±24) ml(20-100 ml). The time of postoperative exhaust was (2.5±0.9) days(2-3 d), the time of postoperative liquid diet was (2.25±0.87) days(2-3 d), postoperative hospital stay was (9.5±2.1) days(6-13 d). No surgical complications such as bleeding, anastomotic fistula or anastomotic stenosis occurred. Postoperative pathology showed that the proximal and distal margins of resected specimens were negative. Patients were followed up for 2 to 15 months, respectively. No death or tumor recurrence and metastasis occurred during the follow-up period. There were no symptoms of reflux after operation. Compared with total gastrectomy and proximal gastrectomy, total laparoscopic cardia function preserving gastrectomy can theoretically reduce the incidence of reflux esophagitis. We used manual suture method for digestive tract reconstruction, which can reduce the application of 2-3 stapling studs and reduce the cost of surgical materials. Compared with subtotal gastrectomy, total laparoscopic cardia function preserving gastrectomy has the advantages of more thorough lymph node dissection, with little residual gastric tissue; therefore, the blood supply is relatively better. The incidence of reflux esophagitis of total laparoscopic cardia function preserving gastrectomy for gastric cancer may was lower than total gastrectomy.

Patients with dementia with Lewy body(DLB), Alzheimer disease (AD), frontotemporal dementia (FTP), progressive supranuclear palsy (PSP) and healthy controls in the Department of Neurology, the First Affiliated Hospital of Zhengzhou University from August 2019 to March 2021 were recruited, with 3 in each group. Phosphorylated α-synuclein from the skin of DLB patients was detected by skin micro-biopsy and compared with patients with AD, FTP, PSP and health controls. Phosphorylated α-synuclein was found in the skin nerves of the DLB patients, while no α-synuclein were detected in the skin samples of others. Skin phosphorylated α-synuclein may potentially become a diagnostic biomarker of DLB, however further studies are warranted to assess its sensitivity and specificity.

Objective: To investigate the prevalence of atrial cardiomyopathy in patients with different types of acute ischemic stroke and its relationship with cryptogenic stroke. Methods: Patients with acute ischemic stroke within 7 days of onset who were admitted to the Department of Neurology of the First Affiliated Hospital of Zhengzhou University from January to September 2019 were prospectively and consecutively enrolled. All included patients were classified according to TOAST classification of ischemic stroke. Chi-square test was used to compare the prevalence of atrial cardiomyopathy among patients with different TOAST classifications. Multivariate logistic regression model was used to analyze the related factors of cryptogenic stroke. Results: A total of 1 098 patients with acute ischemic stroke were enrolled in the study, including 661 males and 437 females, with a median age [M(Q1,Q3)] of 61 (53, 68) years. The prevalence of atrial cardiomyopathy in patients with cryptogenic stroke[53.5% (46/86)] was higher than that in patients with large artery atherosclerosis [38.0%(63/166), P=0.018] and small vessel occlusion [19.4%(37/191), P<0.001], but was lower than that of patients in the cardioembolic group [97.3% (72/74), P<0.001]. Multivariate logistic regression analysis showed that atrial cardiomyopathy was an associated factor for cryptogenic stroke (OR=2.945, 95%CI: 1.766-4.911, P<0.001). Conclusions: Atrial cardiomyopathy is associated with cryptogenic stroke. The prevalence of atrial cardiomyopathy in patients with cryptogenic stroke is higher than that in patients with large artery atherosclerosis and small vessel occlusion, but lower than that in patients with cardiac embolism.

Objective: To analyze the labor progression characteristics of primiparous term singleton pregnant women with adenomyosis. Methods: From April 2014 to May 2021, pregnant women underwent regular antenatal examination in Peking University Third Hospital were enrolled in this retrospective study, 109 primiparous term pregnant women with adenomyosis who underwent singleton, primipara, cephalic and vaginal delivery were referred as the adenomyosis group, while 109 pregnant women without adenomyosis primiparous term pregnant women at the same time were referred as the control group. The general clinical information, labor process intervention, pregnancy outcomes and labor course time of the two groups were analyzed. Results: (1) General clinical conditions: the pre-pregnancy uterine volume of the adenomyosis group was larger than that of the control group [(66.8±23.7) vs (41.4±13.1) cm3, P<0.05]. The proportion of assisted reproductive pregnancy and endometriosis in the adenomyosis group were higher than those in the control group [31.2% (34/109) vs 7.3% (8/109); 31.2% (34/109) vs 5.5% (6/109); all P<0.05]. There were no significant differences in maternal age, gestational age at delivery, pre-pregnancy body mass index, gestational weight gain, gravidity, incidence of pregnancy complications (gestational diabetes mellitus, pre-eclampsia and thyroid diseases) and premature rupture of membranes between the two groups (all P>0.05). (2) Labor process intervention and maternal and fetal outcomes: postpartum hemorrhage was higher in the adenomyosis group than the control group (median: 300 vs 260 ml, P=0.018). There were no significant differences in the proportion of labor onset, use of oxytocin, artificial rupture of membranes, perineal laceration â ¢ and above, episiotomy, newborn weight and 1-minute Apgar score between the two groups (all P>0.05). (3) Time of labor process: there were no significant differences between the two groups in the time required for the first stage, third stage, total stage and cervical dilation 0-1, 1-2, 2-3, 3-4, 4-5, 5-6, 6-7 cm (all P>0.05). The time required for cervical dilation 7-8, 8-9, 9-10 cm and the second stage of labor in adenomyosis group (median: 20, 18, 15 and 12 minutes, respectively) were shorter than those of the control group (median: 23, 23, 23 and 26 minutes, respectively), and the differences were statistically significant (all P<0.05). (4) The effect of endometriosis on labor: there was no significant difference in the effect of endometriosis on labor in adenomyosis group (P>0.05). Conclusions: The labor process of primiparous term pregnant women with adenomyosis is significantly accelerated after the cervical dilatation for 7 cm, which should be closely observed. The third stage of labor course is managed aggressively with drugs to prevent postpartum hemorrhage.

Objective: To explore accurate prenatal diagnosis, full-coverage graded counseling and follow-up for the fetus with cardiac birth defects (CBD). Methods: CBD fetus diagnosed prenatal by echocardiography from January 2018 to December 2020 in Guangdong Provincial People's Hospital were enrolled. Fetal CBD was graded (â -â ¥) according to prognosis and possible operation time after birth, and the classification criteria and common diseases included were proposed. After the prenatal grading counseling, the outcome of the fetus was followed-up. The induced labor rate, live birth rate, prenatal and postnatal ultrasound diagnosis coincidence rate and other indicators were calculated. The disease composition ratio, prognosis of fetus with different grades and the outcome of integrated treatment were analyzed. Results: The detection rate of fetal CBD was up to 16.2% (1 971/12 188), 30 cases of which were excluded. A total of 1 941 cases were included in this study, including 196 cases (10.1%) of gradeâ , 433 cases (22.3%) of gradeâ ¡, 615 cases (31.7%) of grade â ¢, 261 cases (13.4%) of grade â £, 388 cases (20.0%) of gradeâ ¤, 48 cases (2.5%) of grade â ¥. Grade â ¡ and gradeâ ¢ (the operation time was within 1 year after birth) accounted for 54.0% (1 048/1 941). The distribution of some diseases in different grades had obvious proportion advantage, which was representative. Among 1 747 CBD fetus, 736 cases (induced labor rate 42.1%) chose to terminate pregnancy due to CBD. Of the 1 010 live births, 975 cases (96.5%) had the same prenatal and postnatal diagnosis, 3 cases were missed diagnosis and 32 cases were misdiagnosed. The diagnostic accuracy of live births with severe and complex congenital heart disease was 383 out of 389 (98.5%). A total of 258 cases have received surgery or intervention. The age at the time of surgery or intervention was different among gradesï¼χ²=47.3ï¼P<0.001ï¼. With the improvement of prognosis from gradeâ to â ¤, the live birth rate increased and the induced labor rate decreased accordingly; the difference between grades was significantï¼χ²=623.6ï¼P<0.001ï¼. Conclusions: Prenatal diagnosis and graded counseling is important in the integrated model. Fetal CBD grading could refine post-natal treatment strategies, guide delivery decisions and become an evaluation standard.
