Premature ejaculation refers to a sexual dysfunction in which men experience a short intravaginal ejaculation latency and a lack of control over ejaculation during sexual activity. The onset of this condition is often accompanied by anxiety and depression, which can seriously affect the quality of the patient′s sexual life and the relationship between partners. Based on the "integration of body and spirit" theory in traditional Chinese medicine, our team believes that this condition is a comorbidity of physical and spiritual factors. We propose that the core pathogenesis of this disease lies in the "loss of form and essence, impairment of spirit, and depression of the mind, "while the primary treatment principle involves "nourishing form and regulating spirit." As a result, a new diagnosis and treatment approach of "four-dimensional integration" is summarized in this study. The disease is treated through the four dimensions of shape, body, spirit, and emotion. Traditional Chinese medicine is used to adjust the shape in cases where the physical form is damaged. For individuals with depression of heart and liver qi, the treatment focuses on soothing the heart and smoothing liver qi, and the modified Wangyou Powder and Xuanzhi Decoction is used. In cases where the heart and kidney function are compromised, the treatment involves nourishing both the heart and kidney while restoring interaction between the heart and the kidney, and modified Jihuo Yansi Elixir is used. To reduce the sensitivity of the glans penis, the patient′s body is washed with a traditional Chinese medicine formula, and a delicate fumigation formula is decocted for external washing. For those who are not in tune with their god, psychological counseling can be used to regulate their spirit and advocate "self-partner" and psychotherapy. If there are issues with intimacy, partners should focus on cooperating during foreplay, sexual intercourse, and post-coital interactions. Overall, the treatment aims to harmonize the body and spirit, addressing both physical and psychological factors through a comprehensive, multi-dimensional approach. This method provides new perspectives and ideas for the clinical diagnosis and treatment of this condition.

Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective:To investigate the clinical effect of free anterolateral thigh myocutaneous flap combined with oral repair membrane in the reconstruction of nasal mucosa defect after maxillary malignant tumor surgery. Methods:A total of 12 patients with maxillary gingival squamous cell carcinoma and maxillary sinus cancer who had been treated in Department of Oral and Maxillofacial Surgery, Beijing Anzhen Nanchong Hospital, Capital Medical University & Nanchong Central Hospital, were selected from November 2020 to November 2023. Free anterolateral thigh musculocutaneous flap transplantation combined with oral repair membrane were used in all patients. Meanwhile, maxillary soft and hard tissue defects and nasal mucosa defects left after tumor operation were repaired and reconstructed. The clinical effect was evaluated after 6-12 months follow-up. Results:Subtotal maxillary resection was performed in 1 case, total maxillary resection in 9 cases and extended maxillary resection in 2 cases. The musculocutaneous flaps of all patients survived, the facial appearance was basically symmetrical, no obvious depression deformity, the swallowing and speech function recovered well, the mouth and nasal cavity were closed completely, the food could be eaten through the mouth, and the lower nasal passage was not blocked. Conclusion:The free anterolateral thigh musculoflap combined with oral repair membrane can be used to repair and reconstruct maxillary malignant tumor complicated with extensive maxillary tissue and nasal mucosa defect after operation, and the appearance and function can be recovered well after operation, which is a choice for maxillary malignant tumor complicated with nasal mucosa defect.

Surgery is the mainly treatment for rectal cancer. Rectal cancer surgery currently poses specific challenges due to the complex anatomy of pelvic and narrow operating area. Three-dimensional(3D) modelling transforms two-dimensional images into three-dimensional models, makes medical imaging more intuitive and closer to the real surgical procedure. 3D modelling can reconstruct lesions along with surrounding structures, such as organs, vessels, and nerves, thereby enhancing disease diagnosis and treatment. Currently, 3D modelling technology has played a significant role in preoperative planning, intraoperative navigation, medical education, and other fields in orthopedics, urology, thoracic surgery and other surgery. However, its application in rectal surgery is still in the exploratory stage. This article provided a review of the relevant research and progress of 3D modelling in rectal cancer surgery, to improve the development of this technology.

Objective:To describe the trend of mortality and death spectrum in Shandong Province from 1970 to 2021 and provide basis for the targeted disease prevention and control.Methods:The data were collected from the death registration reports of Shandong and 3 national retrospective surveys of death causes in Shandong. The change in levels of overall and specific deaths in Shandong in different years were analyzed based on mortality rate, age-standardized mortality rate and constituent ratio of cause of death, differential decomposition was used to quantify the contribution of demographic and non-demographic factors to changes of mortality.Results:The crude mortality rate in residents in Shandong was basically stable from 1970 to 2021, and the mortality rate during 2020-2021 (732.73/100 000) was slightly higher than that during 1970-1974 (671.98/100 000). While the standardized mortality rate decreased significantly, and the mortality during 2020-2021 (183.39/100 000) decreased by 67.71% compared with that during 1970-1974 (568.00/100 000). The negative increase of population factors and the positive decrease of non-population factors reacted each other, so the mortality was relatively stable. Cardiac-cerebrovascular disease was always the leading cause of death, but the constituent ratio of death increased rapidly from 19.70% during 1970-1974 to 54.72% during 2020-2021. The rank in the causes of death changed from the fourth (11.46%) to the second (25.70%) for malignant tumor, from the seventh (5.85%) to the third (5.59%) for injury, from the second (12.87%) to the fourth (4.99%) for chronic respiratory diseases, from the third (12.27%) to the tenth (0.42%) for infectious diseases. The standardized mortality rates of the main causes of death decreased at different degrees, the standardized mortality rates of obstetrical disease, infectious disease, gastrointestinal disease and chronic respiratory disease decreased by more than 50.00%. The age distribution of deaths and the death spectrum in different age groups and in urban-rural populations changed significantly. During 2020-2021, the proportion of deaths in young people aged 0-14 years was 0.54%, which was 97.05% lower than that during 1970-1974, while the proportion of deaths in the elderly aged ≥75 years was 55.14%, which was 55.75% higher than that during 1970-1974. The rank of infectious diseases in the causes of death descended significantly in all age groups, but the ranks of injury, neuropsychiatric disease and malignant tumor rose significantly in adolescents, and the ranks of endocrine nutrition and metabolic disease rose in middle-aged and elderly people. The difference of death spectrum between urban area and rural area became less obvious and the main death causes in urban and rural residents were basically the same during 2020-2021.Conclusions:The death spectrum of residents in Shandong changed significantly. Chronic and non-communicable diseases, especially cardiac-cerebrovascular disease and malignant tumor, should be the focus in disease control and prevention. The prevention and control of diseases in Shandong made remarkable achievement during 1970-2021. However, in the context of population ageing, it is suggested to strengthen the treatment, prevention of diseases and injuries related to the health of the elderly and elderly health care in the future.

Objective:To understand the characteristics and trends of acute myocardial infarction (AMI) in Shandong Province and to provide evidence for formulating prevention and control strategies.Methods:Data were derived from the AMI incidence reports of Shandong Province's Chronic Disease Surveillance Information Management System in 2012-2021. The crude and standardized incidence rates were used as indicators to describe the incidence level of AMI. Joinpoint regression analysis was used to analyze the trends in the incidence and age of onset over the years. The contribution of population aging to the increase in AMI incidence was assessed using the rate difference decomposition method. The incidence of AMI in each district (county) in Shandong Province was visualized using ArcGIS 10.8 software, and global and local spatial autocorrelation analysis was performed using DeoDa 1.12 software.Results:From 2012 to 2021, 198 233 cases of AMI were reported from 19 provincial monitoring sites in Shandong Province, of which 53.13% were males and 97.12% were ≥45 years old. The reported crude incidence increased from 90.12 per 100 000 in 2012 to 176.54 per 100 000 in 2021, with an average annual increase of 7.01% ( Z=7.35 , P<0.001). There was no significant upward trend in standardized incidence ( Z=1.64 , P=0.140), but the standardized incidence of male residents showed an increasing trend ( Z=2.76 , P=0.028). Before 2014, the reported crude incidence of males was similar to that of females, but after 2014, the reported crude incidence of males was continuously higher than that of females. However, males' standardized incidence was higher than females in all years. Both crude and standardized incidence rates were higher in rural residents than in urban areas. The median onset of AMI increased from 71.6 years old in 2012 to 73.5 years old in 2021. The median age of onset in males was lower than that in females in all years, and in most years, the median age of onset in urban residents was lower than that in rural residents. The incidence of AMI in males showed a trend in younger age groups. According to the seasonal decomposition, the incidence peak of AMI was in January, and the trough was in September. The contribution of aging population to the increase in crude incidence of AMI increased from 8.63% in 2013 to 52.58% in 2021. The global spatial autocorrelation analysis showed that the incidence of AMI presented an obvious spatial clustering distribution. Local spatial autocorrelation analysis found that the high-incidence areas (counties) were mainly concentrated in Liaocheng City and Dezhou City in the northwest region of Shandong Province and Heze City in the southwest. Conclusions:The incidence of AMI among residents in Shandong Province was rising, with spatial clustering and seasonal clustering characteristics. People aged 45 years and older, male residents, and rural residents were at high risk of developing AMI. There was a certain trend of younger age at onset among men. Targeted prevention and control measures should be taken for high-incidence seasons, high-risk groups, and high-incidence clustering areas in northwestern Shandong Province.

Objective To improve the efficiency of induced differentiation of primitive neural epithelial cells derived from human induced pluripotent stem cells(hiPSCs-NECs)into functional midbrain dopaminergic progenitor cells(DAPs).Methods HiPSCs were cultured in mTeSRTM medium containing DMH1(10 μmol/L),SB431542(10 μmol/L),SHH(200 ng/mL),FGF8(100 ng/mL),purmorphamine(2 μmol/L),CHIR99021(3 μmol/L),and N2(1%)for 12 days to induce their differentiation into primitive neuroepithelial cells(NECs).The hiPSCs-NECs were digested with collagenase IV and then cultured in neurobasal medium supplemented with 1%N2,2%B27-A,BDNF(10 ng/mL),GDNF(10 ng/mL),AA,TGF-β,cAMP,and 1%GlutaMax in the presence of different concentrations of Rho kinase inhibitor Y27632,and the culture medium was changed the next day to remove Y27632.Continuous induction was performed until day 28 to obtain DAPs.Results Human iPSCs expressed the pluripotency markers OCT4,SOX2,Nanog,and SSEA1 and were positive for alkaline phosphatase staining.The hiPSCs-NECs were obtained on day 13 in the form of neural rosettes expressing neuroepithelial markers SOX2,nestin,and PAX6.In digested hiPSCs-NECs,the addition of 5 μmol/L Y27632 significantly promoted survival of the adherent cells,increased cell viability and the proportion of S-phase cells(P<0.01),and reduced the rate of apoptotic cells(P<0.05).On day 28 of induction,the obtained cells highly expressed the specific markers of DAPS(TH,FOXA2,NURR1,and Tuj1).Conclusion Treatment with Y27632(5 μmol/L)for 24 h significantly promotes the survival of human iPSCs-NECs during their differentiation into DPAs without affecting the cell differentiation,which indirectly enhances the efficiency of cell differentiation.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective:To evaluate the healthcare accessibility and quality of diagnosis and treatment services of Internet hospitals in China.Methods:One hundred and eighty Internet hospitals in 60 cities were seleted based on the sampling of development levels in the eastern, central and western regions of China. From April to May 2023, standardized patients methodology was applied to evaluate the accessibility(including the number of Internet hospitals, functional settings, online doctor status, the doctor′s attending rate and consultation fees) and diagnosis and treatment service quality(including the diagnosis and treatment services quality, response speed and patient′s evaluation) of Internet hospitals.Results:The average opening rate of Internet hospitals in China was 52.9% (560/1 058), the average online rate of doctors was 64.2% (1 099/1 713), the average doctor′s attending rate was 33.6% (112/333), the average consultation fee was 4.85 yuan, the average score of consultation was 1.92 out of 9, the average score of diagnosis and treatment was 1.12 out of 4, the average score of the response speed was 1.70 out of 3, and patient satisfaction was 2.73 out of 3.Conclusions:The Internet hospital accessibility in China is unevenly developed, and the overall quality of diagnosis and treatment is low. It is recommended to accurately position and optimize the function of Internet hospital, establish the incentive mechanism for online consultation doctors, construct and improve the regulatory system of Internet hospital diagnosis and treatment, so as to improve the accessibility and quality of diagnosis and treatment of Internet hospitals.
