The theory of "brain-heart-kidney-semen chamber" axis is proposed based on the basic theories of traditional Chinese medicine， the modern physiological characteristics of men's diseases， and clinical practice. According to this theory， dysfunctions of the brain， heart， kidney， and semen chamber are the core mechanisms for the occurrence of premature ejaculation， and the loss of control of the opening and closing of the seminal orifices due to the dysfunction of the semen chamber is the final link in the occurrence of premature ejaculation. The treatment of premature ejaculation based on the theory of "brain-heart-kidney-essence chamber" axis highlights the overall regulation of the Zang-fu organs involved in the disease， while focusing on the simultaneous treatment of the mind and body. By exploring the biological basis of the "brain-heart-kidney-essence chamber" axis and premature ejaculation， we propose that the biological basis of premature ejaculation and the axis is mainly related to the function decline of the local brain area， neuromodulation malfunction， central neurotransmitter imbalance， endocrine disorders， and enhanced sensory afferents of the penis. This study aims at providing a new approach for the prevention and treatment of premature ejaculation by traditional Chinese medicine and a scientific basis for the development of more effective therapeutic methods.

Objective: To explore the association between processed food consumption and anxiety symptoms among college students in Yunnan Province, so as to provide a reference for the prevention and treatment of anxiety symptoms in this population. Methods: A cluster random sample of 2 515 first year students from two universities in Yunnan Province was selected to carry out a longitudinal investigation which included a baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The food frequency questionnaire was administered to assess processed food consumption, and the Depression Anxiety Stress Scale-21 (DASS-21, Chinese version) was used to evaluate anxiety symptoms. A generalized estimation equation model was used to analyze the relationship between processed food consumption and anxiety symptoms. Results: The detection rates of T1-T4 anxiety symptoms among college students in Yunnan Province were 29.70%, 36.70%, 37.69% and 38.73 %, respectively, and the corresponding anxiety symptom scores were 4(0,8), 4(0,10), 4(0,12), 2(0,14). After controlling for demographic variables and confounding factors in the generalized estimation equation model, a statistically significant association was found between consumption of carbonated beverages ( β=0.06, 95%CI =0.03-0.08), and other processed snacks ( β= 0.04 , 95%CI =0.01-0.07) ( P <0.05). The stratified analysis by gender showed that the consumption of carbonated beverages ( β=0.08, 95%CI =0.05-0.12) and fast food ( β=0.03, 95%CI =0.00-0.06) was significantly associated with anxiety symptoms in female college students ( P <0.05). There was no significant association between processed food consumption and anxiety symptoms in male college students ( P >0.05). Conclusions Processed food consumption by college students in Yunnan Province may increase the risk of anxiety symptoms, particularly among female students. There is a need to strengthen guidance in respect to processed food consumption, so as to prevent and treat anxiety symptoms.

Objective To analyze the epidemic characteristics of pneumoconiosis in Jingmen City from 2011 to 2022, and to provide theoretical basis for formulating the occupational disease prevention plan of the ^“14th Five-Year Plan^” in Jingmen City. Methods The data of pneumoconiosis cases in Jingmen City from 2011 to 2022 were collected from the Occupational Disease and Health Hazard Factors Monitoring Information System, and the information of disease classification, enterprise economic type, scale distribution, regional distribution, job distribution, dust exposure years and so on was statistically analyzed.

The cases were mainly distributed in Dongbao District with 160 cases (61.54%), Zhongxiang City with 72 cases (27.69%), and Duodao District with 18 cases (6.92%). The difference was statistically significant（χ²=217.846，P<0.05）. The cases were mainly distributed in private enterprises (76.54%, 199 cases). The enterprise sizes were mainly medium-sized (28.46%, 74 cases) and small (61.15%, 159 cases) enterprises, and the difference was statistically significant (χ²=46.025，P<0.05). Conclusion Coal workers' pneumoconiosis and silicosis are the main types of occupational pneumoconiosis in Jingmen area, which will become the key prevention and control targets in Jingmen City for a long time and should be paid attention to. The cases are mainly concentrated in joint-stock, private economic type enterprises and small and medium-sized enterprises, which should be monitored intensively.

Male lower urinary tract symptoms is a collective term for a group of symptoms associated with lower urinary tract disorders characterized by frequent urination, urgent urination, and difficulty of urination, of which the common causes are benign prostatic hyperplasia or overactive bladder. With the aging of the global population, the incidence of male lower urinary tract symptoms is increasing year by year. Based on the theoretical connotation of " zang-fu extraordinary connection", the relationship between the lungs and the bladder, the spleen and the small intestine, and the kidneys and the sanjiao with the formation of male lower urinary tract symptoms is explained from three perspectives. It is believed that lung qi depression and closure, disturbance of qi transformation in bladder, and insufficient spleen transport occur, the small intestine is dysfunctional, kidney yang is exhausted, and obstruction of the sanjiao waterway are the basic pathogenesis of male lower urinary tract symptoms. It is emphasized that the location of the disease should be identified. If it is related to the lungs and the bladder, then the disease should be treated by lifting the pot to lift the lid and diffusing the lung qi to benefit the bladder with Wuling Powder plus perilla leaf and bitter apricot seed; if it is related to the spleen and the small intestines, then the disease should be treated by raising the clear and directing the turbid downward and improving the spleen qi in order to support the small intestines with Shenling Baizhu Powder; if it is related to the kidneys and the sanjiao, then the disease should be treated by seeking the yang within the yin and warming and tonifying the kidney qi in order to dredge up the sanjiao with Bawei Shenqi Pill. According to the patient's condition, treatment can be combined with acupuncture, exercise, and other therapies. This paper can provide reference for clinical treatment of male lower urinary tract symptoms.

Objective: To study the relationship between sugar sweetened beverages consumption characteristics and insomnia of college students in Yunnan Province, so as to provide evidence for sleep quality improvement of college students. Methods: A cluster random sampling method was used to select 2 515 college students from two universities (Kunming University and Dali Nursing Vocational College) in Kunming and Dali in Yunnan Province for a longitudinal study, including baseline survey (T1, November 2021) and three follow up surveys (T2: June 2022, T3: November 2022, T4: June 2023). Sugar sweetened beverages consumption of college students was collected by Semi quantitative Food Frequency Questionnaire and insomnia was assessed by Insomnia Severity Index Scale. Sugarsweetened beverages consumption was analyzed by Kruskal-Wallis test. The Mann-Whiter U test and Kruskal-Wallis test were used to compare the detection rate of insomnia in college students with different population characteristics, and the generalized estimating equations model was established to analyze the association between sugar sweetened beverages consumption and insomnia. Results: The reported rate of insomnia among college students from T1 to T4 was 21.2%, 23.6%, 30.5 % and 36.0%, respectively. The median of sugar sweetened beverages consumption per week was 5 (1,9) bottles per person, and there were significant differences in sugar sweetened beverages (carbonated beverages, fruit beverages, tea beverages, milk beverages, energy beverages) consumption among college students with different insomnia status ( χ 2=42.91, 23.67, 29.98, 61.70, 30.82, P <0.01). The analysis of the generalized estimating equation model revealed that the consumption of carbonated beverages ( β= 0.04, 95%CI =0.00-0.08) and the consumption of milk beverages among college students ( β=0.04, 95%CI =0.00-0.09) were correlated with insomnia ( P <0.05). The stratified analysis indicated that consumption of carbonated beverages by female college students was associated with insomnia [ β(95%CI )=0.06(0.01-0.11)]; consumption of milk beverages among college students from middle income family was associated with insomnia [ β (95% CI )=0.05(0.00-0.10)], and consumption of carbonated beverages and fruit beverages from college students with high household economic status were both associated with insomnia [ β (95% CI )=0.35(0.23-0.46), 0.12(0.00-0.24)] ( P <0.05). Conclusion Sugar sweetened beverages, especially carbonated beverages, are associated with insomnia among college students in Yunnan Province.

Hepatocellular carcinoma is a kind of cancer with a strong invasion, a high incidence rate and mortality, and a poor prognosis. At the time of diagnosis, most patients are already in the advanced stages of a tumor and have lost the chance for radical surgical treatment. Advanced hepatocellular carcinoma treatment has a gradual transition from systemic chemotherapy to targeted therapy, immunotherapy, and combination therapy, especially immune checkpoint inhibitor-based immunotherapy combination therapy, such as combination with bevacizumab monoclonal antibodies and other drugs, or combination with TACE, HAIC, radiotherapy, ablation, and other treatment methods. Combination therapy has significant synergistic effects and thus has already become a future treatment trend for hepatocellular carcinoma. An immunotherapy-based combination therapy plan will run through the whole process of systemic therapy, which is expected to bring better survival benefits to patients with hepatocellular carcinoma. This article reviews the latest research progress in aspects of the first-line treatment of advanced hepatocellular carcinoma.

After collcted for the demographic variables and other confounding effects, the analysis results showed that:withdrawal symptoms of mobile phone dependence( OR=1.29, 95%CI =1.09-1.54), physical and mental health impacts of mobile phone dependence ( OR=1.25, 95%CI =1.10-1.43) and craving of mobile phone dependence ( OR=1.20, 95%CI =1.06-1.36) were associated with constipation in college students( P <0.01). Conclusion Mobile phone dependence may increase the risk of constipation of college students in Yunnan Province, so health education should be strengthend.

Objective To investigate the influence of gravity levels on lower limb motions during human walking. Methods A suspended microgravity simulation system was designed for the experiment. Kinetic parameters from lower limb joints of twelve volunteers during walking were measured by the motion capture system and 3D force plate under simulated Mars gravity (1/3 G), lunar gravity (1/6 G) and earth gravity (1 G). Results Under simulated Mars and lunar gravity, the ranges of motion (ROMs) of hip and knee joints in sagittal plane significantly decreased (P＜0.01) while the ROMs of ankle joints obviously increased (P＜0.05). The ROMs of hip, knee and ankle joints in sagittal plane under earth gravity were 45.2°, 67.7°, 32.5°, respectively, while the ROMs of hip, knee and ankle joints under lunar gravity were 25.1°, 50.8°, 42.4°, respectively. In addition, the force and torque of lower limb joints in sagittal plane under lower gravity also decreased significantly (P＜0.01). Conclusions The results obtained by this study were almost the same as the research findings obtained by using treadmill. Astronauts can use the treadmill and microgravity simulation system for walking exercises under lunar gravity on the earth.

Objective: To explore the application value of protective device in microwave ablation at canine liver risk area, and the role of the device in reducing complications during ablation. Methods: Six healthy mongrel dogs were randomly divided into two groups: group A, used protective devices; group B, unprotected. Conventional gray-scale ultrasound and contrast-enhanced ultrasound (CEUS) were performed before treatment to identify the ablation area (the right lobe of the liver near diaphragm, 1 cm from the surface of the liver). The two groups were treated percutaneous puncture liver microwave ablation under real time ultrasound-guided with the same ablation power (50 W) and equivalent ablation time (600 s). Liver specimens were evaluated histological examination to evaluate the necrotic area of ablation and the degree of diaphragm′s injury. Results: ①There was no significance difference in the ablation range between two groups[ (3.3±0.1)cm vs (3.5±0.1)cm, P=0.184]; ②The tolerance of group A was better than group B during ablation treatment; ③The mean maximum ablation diameter in group A was significantly lower than that in group B [(2.1±0.1)cm vs (5.3±0.2)cm, P=0.001]. Meanwhile the pathological results showed that the damage degree in group A was significantly lower than that in group B. Conclusions This protective device has an obvious protective effect for microwave ablation of the risk area in liver (adjacent diaphragm, hepatic envelope). Our experiment suggests that this protective can reduce the damage of adjacent organ and the complications during the ablation surgery.
