Objective To evaluate the pharmacokinetics and safety of dapoxetine hydrochloride tablets in healthy Chinese subjects,and to assess the impact of food on dapoxetine pharmacokinetics.Methods A single-center,open-lable,two-period,randomized parallel study was conducted.A total of 22 healthy adult male subjects were enrolled and administered a single 30 mg oral dose of dapoxetine hydrochloride tablets,both under fasting and fed condition.Venous blood samples were collected at different time points,and dapoxetine concentrations in human plasma were measured using liquid chromatography tandem mass spectrometry(LC-MS/MS).Pharmacokinetic parameters were calculated using Phoenix WinNonlin 6.3 software,and statistical analysis was conducted with SPSS 19.0 software.Results The main pharmacokinetic parameters after oral administration of dapoxetine hydrochloride tablets in fasting and fed were as follows:Cmax were(230.71±88.91)and(216.27±58.32)ng·mL-1;AUC0-t were(1 054.99±442.11)and(1 292.56±534.49)ng·h·mL-1;AUC0-∞ were(1 175.03±510.58)and(1 447.42±656.25)ng·h·mL-1;tmax were(1.23±0.59)and(2.40±0.90)h;t1/2 were(15.95±6.13)and(16.21±6.34)h.Comparisons between the fasting and fed states,showed statistically significant differences in AUC0-t,AUC0-∞ and tmax(all P＜0.05),but not in Cmax and t1/2(all P＞0.05).The incidence of adverse events was 31.82％in the fasting state and 22.73％in the fed state,with no significant difference(P＞0.05).Conclusion Dapoxetine hydrochloride tablets were rapidly absorbed and eliminated in both fasting and fed states,with good safety;food slowed the absorption rate of dapoxetine and increaseed its overall exposure.

Objective:To describe the distribution of lipoprotein (a) [Lp(a)] levels in non-arteriosclerotic cardiovascular disease (ASCVD) population in China and explore its influencing factors.Methods:This study was based on a nested case-control study in the CKB study measured plasma biomarkers. Lp(a) levels was measured using a polyclonal antibody-based turbidimetric assay certified by the reference laboratory and ≥75.0 nmol/L defined as high Lp(a). Multiple logistic regression model was used to examine the factors related to Lp(a) levels.Results:Among the 5 870 non-ASCVD population included in the analysis, Lp(a) levels showed a right-skewed distribution, with a M ( Q1, Q3) of 17.5 (8.8, 43.5) nmol/L. The multiple logistic regression analysis found that female was associated with high Lp(a) ( OR=1.23, 95% CI: 1.05-1.43). The risk of increased Lp(a) levels in subjects with abdominal obesity was significantly reduced ( OR=0.68, 95% CI: 0.52-0.89). As TC, LDL-C, apolipoprotein A1(Apo A1), and apolipoprotein B(Apo B) levels increased, the risk of high Lp(a) increased, with OR (95% CI) for each elevated group was 2.40 (1.76-3.24), 2.68 (1.36-4.93), 1.29 (1.03-1.61), and 1.65 (1.27-2.13), respectively. The risk of high Lp(a) was reduced in the HDL-C lowering group with an OR (95% CI) of 0.76 (0.61-0.94). In contrast, an increase in TG levels and the ratio of Apo A1/Apo B(Apo A1/B) was negatively correlated with the risk of high Lp(a), with OR (95% CI) of 0.73 (0.60-0.89) for elevated triglyceride group, and OR (95% CI) of 0.60 (0.50-0.72) for the Apo A1/B ratio increase group (linear trend test P≤0.001 except for Apo A1). However, no correlation was found between Lp(a) levels and lifestyle factors such as diet, smoking, and physical activity. Conclusions:Lp(a) levels were associated with sex and abdominal obesity, but less with lifestyle behaviors.

Objective Tissue uptake and distribution of nano-/microplastics was studied at a single high dose by gavage in vivo.Methods Fluorescent microspheres (100 nm, 3 μm, and 10 μm) were given once at a dose of 200 mg/(kg·body weight). The fluorescence intensity (FI) in observed organs was measured using the IVIS Spectrum at 0.5, 1, 2, and 4 h after administration. Histopathology was performed to corroborate these findings.Results In the 100 nm group, the FI of the stomach and small intestine were highest at 0.5 h, and the FI of the large intestine, excrement, lung, kidney, liver, and skeletal muscles were highest at 4 h compared with the control group (P < 0.05). In the 3 μm group, the FI only increased in the lung at 2 h (P < 0.05). In the 10 μm group, the FI increased in the large intestine and excrement at 2 h, and in the kidney at 4 h (P < 0.05). The presence of nano-/microplastics in tissues was further verified by histopathology. The peak time of nanoplastic absorption in blood was confirmed.Conclusion Nanoplastics translocated rapidly to observed organs/tissues through blood circulation;however, only small amounts of MPs could penetrate the organs.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective:To explore the diagnostic value of first-trimester and mid-trimester ultrasound in screening fetal pentalogy of Cantrell, and to analyze missed and misdiagnosed cases.Methods:The fetal ultrasound image characteristics of pentalogy of Cantrell diagnosed in the Affiliated Suzhou Hospital of Nanjing Medical University from March 2018 to November 2022 were retrospectively analyzed. The necessary sections and key features of ultrasound images for diagnosing the disease in first-trimester and mid-trimester were summarized. The diagnostic value of ultrasound screenings in first-trimester and mid-trimester was analyzed, and the progression of the disease during pregnancy was understood, the missed diagnosis rate and misdiagnosis rate were calculated, and the reasons for missing diagnosis were analyzed. All fetuses were followed up to birth or induction of labor.Pentalogy of Cantrell was divided into types Ⅰ, Ⅱ, and Ⅲ according to Toyama′s research.Results:Among the 120 190 fetuses, 13 cases of pentalogy of Cantrell were diagnosed by ultrasound in first-trimester and mid-trimester. Ultrasound predominantly showed the fetal heart being malpositioned outside the chest and the fetal abdominal contents bulging outside the abdominal cavity, and the sternumal echo was partially or completely missed in some cases. All 13 cases were confirmed by follow-up, including 1 case of type Ⅱ, and 12 cases of type Ⅲ. In addition, 1 missed case of type Ⅱ pentalogy of Cantrell was followed up after birth. The correct diagnostic rates of fetal pentalogy of Cantrell using standard ultrasound sections during the first-trimester and mid-trimester were 99.9% and 100%, the sensitivity were 88.9% and 100%, the specificity were both 100%, the positive predictive values were both 100%, and the negative predictive values were 99.9% and 100%, respectively.Conclusions:First-trimester and mid-trimester ultrasound screenings have high diagnostic accuracy for pentalogy of Cantrell, and early detection and early diagnosis are of great clinical significance for the guidance of pregnancy outcomes.

Objective To explore the effect of long non-coding RNA(lncRNA)microRNA 17-92 cluster host gene(MIR17HG)regulating microRNA(miR)-214-3p/ring finger protein 38(RNF38)signal axis on the malignant biological behavior of liver cancer cells.Methods The cancer tissues and adjacent tissues of 46 patients with liver cancer who underwent surgical resection in our hospital from May 2022 to October 2023 were collected to detect the expression of lncRNA MIR17HG,miR-214-3p and RNF38.HepG2,Bel-7402,SMMC-7721 and HL-7702 cells were cultured in vitro,and the expression of lncRNA MIR17HG,miR-214-3p and RNF38 was compared,Bel-7402 cells were selected for further study,and randomly divided into sh-NC group,sh-MIR17HG group,anti-NC group,anti-miR-214-3p group and Bel-7402 group.The proliferation,apoptosis,invasion and migration of Bel-7402 cells in each group were investigated,the expression of RNF38,caspase-3(caspase-3),B cell lymphoma-2(Bcl-2),matrix metalloproteinase-2(MMP2)and matrix metalloproteinase-9(MMP9)protein was analyzed by western blotting,the relationship between lncRNA MIR17HG and miR-214-3p and the relationship between miR-214-3p and RNF38 were verified by double luciferase.Results The mRNA expression of lncRNA MIR17HG and RNF38 in liver cancer tissues was higher,the mRNA expression of miR-214-3p was lower,and the positive expression rate of RNF38 protein was higher(P＜0.05).The expression of lncRNA MIR17HG mRNA,RNF38 mRNA and RNF38 protein in SMMC-7721,HepG2 and Bel-7402 cells was higher than that in HL-7702 cells,and the expression of miR-214-3p mRNA was lower than that in HL-7702 cells(P＜0.05).Compared with Bel-7402 group and sh-NC group,the OD450nm value,the number of cloned cells,the number of invasive cells,the number of migrated cells and the expression of RNF38,MMP2,Bcl-2 and MMP9 in sh-MIR17HG group decreased,while the apoptosis rate and the expression of caspase-3 increased(P＜0.05).Compared with sh-MIR17HG group and anti-NC group,the OD450nm value,the number of cloned cells,the number of invasive cells,the number of migrated cells and the expression of RNF38,MMP2,Bcl-2 and MMP9 in anti-miR-214-3p group increased,while the apoptosis rate and the expression of caspase-3 decreased(P＜0.05).LncRNA MIR17HG and miR-214-3p,and miR-214-3p and RNF38 have targeted relationships respectively.The luciferase activity in miR-214-3p+WT-MIR17HG group was lower than that in miR-NC+WT-MIR17HG group(P＜0.05),and the luciferase activity in miR-214-3p+WT-RNF38 group was lower than that in miR-NC+WT-RNF38 group(P＜0.05).Conclusion LncRNA MIR17HG may promote the malignant biological behavior of liver cancer cells by regulating the miR-214-3p/RNF38 axis.

Lung cancer has the highest morbidity and mortality in China.Guiding by Chinese medical master ZHOU Dai-Han and based on the experience of diagnosis and treatment of lung cancer in the past 40 years,the authors believe that phlegm is the key to the pathogenesis of lung cancer,and then put forward the phlegm-toxin pathogenesis theory according to the clinical characteristics of lung cancer.Lung cancer is a disease of deficiency in origin and excess in superficiality.Qi deficiency of lung and spleen leads to the formation of phlegm-toxin,and phlegm-toxin is the key pathogenic factor for the development and progression of lung cancer.Based on the phlegm-toxin pathogenesis,the treatment of lung cancer with the method of replenishing qi and removing phlegm(abbreviated as Yiqi Chutan method)is proposed.The clinical practice of the research team in recent years has shown that Yiqi Chutan method is effective in the treatment of middle-to-advanced lung cancer,in particular the middle-to-advanced lung cancer in the elderly,which can prolong the survival time of patients with advanced lung cancer,improve the quality of life of lung cancer patients,relieve lung cancer related symptoms,enhance the efficacy and reduce the toxicity of anti-tumor treatment,and prevent and treat early lung cancer.The study on the anti-tumor mechanism of Yiqi Chutan method showed that the anti-tumor mechanism of Yiqi Chutan Formula was related to the inhibition metastasis of lung cancer,regulation of cell cycle,inhibition of epithelial-mesenchymal transition,regulation of the apoptosis and autophagy of cells,and improvement of the EGFR-TKIs resistance.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
