Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

Objective:To explore whether the Wenpi Yishen method can effectively prevent the occurrence of urinary tract infection after transurethral resection of the prostate (TURP) in patients with benign prostatic hyperplasia (BPH).Methods:A prospective randomized controlled study was conducted on 173 patients with BPH admitted to Beijing Friendship Hospital, Capital Medical University from January 2023 to December 2024, and they were divided into the control group ( n=104) and the Wenpi Yishen group ( n=69) by the random number table method. Patients in the control group were treated only with conventional methods after TURP, while patients in the Wenpi Yishen group were treated with the Wenpi Yishen method in addition to the conventional treatment after TURP to prevent urinary tract infections. The preoperative general data such as age and body mass index of the two groups of patients were compared, as well as the traditional chinese medical syndrome scores before and after TURP, international prostate symptom scores (IPSS), self-rating anxiety scale (SAS) scores, urinary tract infections and postoperative complications, etc. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups; count data were expressed as the cases and percentage, and Chi-square test was used for comparison between groups. Results:There were no statistically significant differences between the two groups of patients in terms of preoperative traditional chinese medical syndrome scores, IPSS scores, SAS scores, and inflammation-related indicators ( P>0.05). In the patients of control group, 44 cases (42.3%) had positive urine cultures before the operation, there was 28 cases (40.6%) in the Wenpi Yishen group, and the difference was no statistically significant ( P>0.05). In the patients of control group, 28 cases showed positive urine cultures within one month after TURP, among which 9 cases were new-onset urinary tract infections, there was 9 cases in the Wenpi Yishen group, and no new-onset urinary tract infections, and the differences were statistically significant ( P<0.05). The traditional chinese medical syndrome scores of patients in the control group and Wenpi Yishen group after surgery were (8.0±2.1) points and (6.9±2.4) points, respectively, and the therapeutic rates of syndromes were (60.2±10.0)% and (65.2±12.2)%, respectively, the differences were statistically significant ( P<0.05). The IPSS score and SAS score of patients in the Wenpi Yishen group decreased by (21.0±4.5) points and (14.7±2.9) points before and after TURP, respectively, which were both lower than those of the control group [(19.1±3.5) points and (11.7±3.7) points], and the differences were statistically significant ( P<0.05). In terms of the severity of postoperative complications, 34 cases (32.7%) in the control group had relatively severe complications such as urinary tract infection and hematuria, while only 5 cases (7.25%) in the Wenpi Yishen group, and the difference was statistically significant ( P<0.05). However, there was no statistically significant difference in the postoperative inflammation-related indicators between the two groups ( P>0.05). Conclusion:For patients with BPH, early application of the Wenpi Yishen method after TURP can effectively prevent the occurrence of urinary tract infections, and improve the uncomfortable symptoms in the short term after the operation, as well as relieve the generation of anxiety.

Objective With the development of manned space missions to the moon and space exploration,extravehicular activities become more frequent and extravehicular mission become more complex,which puts forward higher requirements for the extravehicular spacesuit.In order to ensure the ergonomics of spacesuit,the flexible joints are usually adopted in the limbs of spacesuit.The structural design of large angle of movement and low resistance joints is the basic for ensuring the ergonomics of spacesuit.Methods This study established a method of spacesuit joint structure to analysis the motion characteristic of typical joints.Firstly,the structure and activity characteristics of the spacesuit and lunar space suits were comprehensively analyzed,and the activity characteristics of different typical structure are qualitatively analyzed based on existing empirical method.Then,the dynamics of typical structure was analyzed by finite element model.By studying the change trend of motion of spacesuit joint with motion angle,and the motion characteristic curve was obtained.Finally,the model was studied according to different structural size parameters.The influence of structural parameters on the motion characteristics was analyzed,and the curves was obtained to provide a basis for design of spacesuit motion joint structure.Results Through the above analysis,the motion characteristics of different typical structure are obtained qualitatively.And the influence of different structure parameters on the motion characteristics was analyzed.This establishes the method basis for structure design.Conclusion The study was carried out a method based on finite element model for joint motion analysis,which is suitable for the design of typical joint structure of spacesuit.

Objective Maintain a sable differential pressure inside the Underwater Positive Pressure Protective Suit(UPPPS)to ensure normal breathing and safe underwater operations for the diver.Methods Utilize a pressure regulator as the UPPPS's pressure control valve to automatically maintain the differential pressure inside the suit.Results By establishing a physical model,the relationship between the steady-state differential pressure with the ventilation flow rate and the ambient pressure was obtained.(1)The ventilation flow rate is positively correlated with the steady-state differential pressure,the higher the ventilation flow rate,the greater the steady-state differential pressure.(2)At the same ventilation flow rate,the larger the ambient pressure is,the smaller the steady-state differential pressure is.Underwater unmanned and manned experiments using the UWT suit were conducted.The expermental results are in agreement with the theoretical analysis.Conclusion The performance of pressure regulator has been verified by the underwater experiments,it effectively stabilizes the differential pressure within the UPPPS.

Based on the pathogenesis of erectile dysfunction (ED) from the meridian-zangfu relationship and the "brain-heart-kidney-essence chamber" axis, it proposes that dysfunction of the "brain-heart-kidney-essence chamber" axis is closely related to the occurrence of ED. Among these, brain-heart disharmony is the key pathogenic factor, kidney deficiency and essence depletion constitute an important basis, and essence chamber stasis is a critical mechanism. The treatment approach emphasizes harmonizing the brain and heart, regulating the mind, tonifying the kidney and replenishing qi, unblocking qi and blood to harmonize the essence chamber. The primary acupoints include Baihui (GV20)-Neiguan (PC6)-Shenmen (HT7), Taixi (KI3)-Guanyuan (CV4)-Sanyinjiao (SP6), and Zhongji (CV3)-Dahe (KI12)-Gongsun (SP4), with additional acupoints selected based on syndrome differentiation. This approach aims to restore the clarity of the brain and heart, replenish kidney qi, and unblock the essence chamber, thereby facilitating the restoration of normal functions of the brain, heart, kidney, and essence chamber, and alleviating ED symptoms and improving overall clinical efficacy.

Objective:To compare the safety and accuracy between robotic-assisted screw placement and free-hand screw placement in adolescent idiopathic scoliosis (AIS) surgery.Methods:The clinical data of 69 AIS patients underwent posterior spinal scoliosis orthomorphia from December 2021 to October 2023 in Beijing Chaoyang Hospital, Capital Medical University were retrospectively analyzed. Among them, 37 patients underwent robot-assisted screw placement (robot group), and 32 patients underwent fluoroscopy-assisted free-hand screw placement (free-hand group). The basic information of surgery (operation time, intraoperative blood loss, intraoperative radiation exposure time, postoperative hospital stay and postoperative complications), screw placement indexes (single screw placement time and accuracy of screw placement) and imaging indexes (main curve correction rate, kyphotic change and lumbar lordosis change) were compared between two groups. The ln curve regression analysis method was used to evaluate the learning curve of robot-assisted screw placement therapy for AIS.Results:A total of 716 screws were placed in 32 patients of free-hand group, and 766 screws in 37 patients of robot group. The operation time, intraoperative radiation exposure time, single screw placement time and accuracy of screw placement in robot group were significantly higher than those in free-hand group: (272.30 ± 67.98) min vs. (221.66 ± 67.32) min, (149.81 ± 57.21) s vs. (116.03 ± 63.10) s, (497.97 ± 51.74) s vs. (381.47 ± 46.58) s and 97.91% (750/766) vs. 91.48% (655/716), and there were statistical differences ( P<0.01 or <0.05); there were no statistical differences in intraoperative blood loss, postoperative hospital stay, incidence of neurological complications, incidence of incision infection and number of screw between two groups ( P>0.05). There were no statistical differences in the main curve correction rate, kyphotic change and lumbar lordosis change between two groups ( P>0.05). When the fitting degree was the highest ( R2 = 0.729, P<0.01), the fitting equation was y = - 50.93ln x + 634.7 ( x was the number of operation, and y was the single screw placement time), and the number of vertices was 12 cases. The robot group was divided into three subgroups according to the order of surgery, subgroup A consisted of 12 patients who underwent the surgery from first to twelfth, subgroup B consisted of 12 patients who underwent the surgery from thirteenth to twenty-fourth, and subgroup C consisted of 13 patients who underwent the surgery from twenty-fifth to thirty-seventh. Among them, the single screw placement time in subgroup A was significantly longer than that in subgroup B and subgroup C: (560.92 ± 35.03) s vs. (465.75 ± 21.20) and (469.62 ± 24.94) s, and there was statistical difference ( P<0.05); there was no statistical difference between subgroup B and subgroup C ( P>0.05). Conclusions:Robot-assisted screw placement for AIS can effectively improve the accuracy of screw placement without affecting deformity correction, but it can increase screw placement time, operation time and radiation exposure time. A smooth learning curve is obtained after performing 12 procedures.

Environmental pollutants generated by industrialization,characterized by microplastics,are increasingly impairing male fertility in the form of"environmental hidden toxins".Although the concept of environmental toxicity has been proposed for a long time,its practical application remains limited.Therefore,this study innovatively introduces and elaborates on the concept of"environmental hidden toxins",highlighting its pathogenic characteristics,including latency,turbidity,consumptive nature,concurrent nature,and transmutation.Environmental hidden toxin can be classified into five categories based on the properties:stagnation toxins,scorching toxins,turbid toxins,desiccating toxins,and latent toxins.The core pathogenesis of environmental hidden toxins-induced male infertility involves three stages:firstly,invading the lungs and spleen,leading to the gradual depletion of healthy qi;secondly,forming toxin-stasis complexes that obstruct the spermatic pathway;and lastly,penetrating deeply into the seminal chamber,directly damaging the genuine essence.The treatment principle emphasizes"strengthening the foundation and clearing the source,"advocating dual strategies of detoxification and strengthening vital qi.This includes enhancing clarity and lowering turbidity,fortifying the earth to generate metal to replenish healthy qi;resolving stasis,unblocking collaterals,and dispelling toxins to eliminate pathogenic factors;and nourishing the kidneys,replenishing essence,and expelling toxins to preserve the genuine essence.All the above approaches form a holistic traditional Chinese medicine(TCM)strategy that treating both manifestation and root cause of disease.The study provides theoretical foundations and offers novel clinical insights into TCM interventions for male infertility caused by environmental pollutants.
