Asthenospermia is one of the important causes of male infertility,and its etiology and pathogenesis are complex.Traditional Chinese medicine(TCM)offers unique advantages in treating this disease.The"kidney deficiency and toxic-stasis"theory reveals the dynamic relationship between kidney essence deficiency and the interaction of toxic-stasis in disease pathogenesis,which can be applied clinically to guide the differentiation and treatment of asthenospermia.The formation of asthenospermia is closely related to the deficiency of kidney essence and the blockage of toxic stasis.The kidney essence is the source of reproductive essence.If the kidney essence is depleted for a long time and the kidney essence is deficient,the essence chamber cannot be enriched,resulting in spermatozoa dysfunction and poor spermatozoa mobility.The poison stasis interferes with the spermatozoa and turns into spermatotoxin,which directly harms spermatozoa fertility and leads to the decrease of spermatozoa mobility.Tongjing Jiedu Formula takes tonifying kidney to supply essence,diuresis and detoxification,activating blood circulation and removing blood stasis as the treatment principle,focusing on tonifying kidney to fill essence and nourishing healthy qi to restore the nourishing effect of kidney essence,and also emphasizes clearing heat and detoxification,activating blood circulation and removing blood stasis,promoting diuresis and dredging collaterals to remove poisonous damp-heat and static blood and harmonize blood and vessel,improving spermatogenic environment and improving sperm vitality to help men have children.This article analyzes the application of Tongjing Jiedu Formula in treating asthenospermia from the perspective of"kidney deficiency and toxic stasis",aiming to provid new ideas and methods for the explanation of the pathogenesis of the disease and TCM treatment.

Varicocele is a common disease of the male reproductive system, and the pampiniform plexus in the spermatic cord manifests abnormal dilatation, extension, and circuity, which is a vasculopathy. In this article, we believe that the relevance of the essence chamber collaterals to the spermatic vein in terms of anatomical morphology and physiological function is high and that when pathogenic qi invades the essence chamber, the qi and collaterals of the essence chamber are out of harmony, the fluid collaterals are impassable, and the blood collaterals are obstrcuted, and the essence chamber collaterals are blockaded with several pathological products, and even intermingled phlegm and blood stasis in the blood collaterals and form vascular clusters, resulting in the formation and development of varicocele. Based on this, this article proposes the core treatment principle of healing, harmonizing, activating, and dredging the collaterals, with the basic treatment method of nourishing qi and harmonizing collaterals, activating blood collaterals, and dredging blood stasis to, respectively treat degree Ⅰ, Ⅱ, and Ⅲ varicocele, aiming to prevent the change of the varicocele, dredge the curvature of the varicocele, and dissipate the knots of the varicocele. The proposal of essence chamber collaterals is of great significance to understanding the common law and pathological aspects of the occurrence and development of essence collateral and vascular lesions from the perspective of integrated traditional Chinese and Western medicine.

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 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.

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.

Objective:To analyze the clinical characteristics of invasive klebsiella pneumoniae liver abscess syndrome (IKPLAS), and compare it with common pyogenic liver abscess (CPLA). Methods:The social demography and clinical data of inpatients with pyogenic liver abscess from January 2011 to December 2021 in the Peking University People's Hospital were collected. Based on the presence or absence of invasive infections and the results of bacterial etiology, IKPLAS was diagnosed and compared with CPLA. The general information, symptoms, past medical history, auxiliary examinations and prognosis indicators of the two groups of patients were compared.Results:Total of 172 patients with pyogenic liver abscess were collected, including 25 cases of IKPLAS. Compared with CPLA group, the proportion of fever in IKPLAS group was lower, the proportion of diabetes history was higher, the proportion of monocytes was lower, and procalcitonin and urea nitrogen were higher(all P<0.05), the proportion of multiple abscesses is higher, and the positive rate of blood culture and the cultivation of klebsiella pneumoniae are both higher (all P<0.05).A total of 9 cases (5.2%) of patients developed septic shock, of which 2 cases (1.2%) died. The IKPLAS group had a higher proportion of ICU admissions ( P<0.05),but but the difference of mortality between the two groups was not statistically significant ( P>0.05). The most common sites of invasion infection in the IKPLAS group are the lungs(22/25), brain(9/25), and eyes(9/25). Conclusions:There are differences in clinical characteristics between IKPLAS and CPLA, the most common sites of invasion infection are the lungs, brain, and eyes, but there is no difference in mortality in this study. For PLA with pathogenic Klebsiella pneumoniae, it is necessary to carefully evaluate the presence of invasive lesions and provide targeted local treatment to better improve prognosis.

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.

Male infertility,a common condition in andrology,falls under the category of"no son"in traditional Chinese medicine(TCM).Unhealthy eating habits and excessive sexual activity,prevalent due to improved living standards,have contributed to the increasing incidence of male infertility.YE Tianshi proposed the theory of"maintaining with the sweet and restoring the body fluids",which emphasizes the importance of ample body fluid for the nourishment of the male essence chamber.Sufficient body fluid is crucial for normal sperm generation.In TCM,the primary pathogenesis of male infertility involves the loss of body fluids and insufficiency of yin essence.Sweet Chinese herbal medicinal is recommended as it nourishes yin,enriches essence,and replenishes male reproductive essence without producing phlegm and dampness.Therefore,when treating male infertility,attention should be given to the use of sweet Chinese herbal medicinal,adhering to the principle of"abundant body fluids nourish kidney yin,and abundant kidney yin supports semen production".Therapies such as purging fire to preserve body fluids with Zengye Decoction,nourishing yin to enrich essence with Guilu Erxian Decoction,benefiting qi to promote fluid production with Buzhong Yiqi Decoction,and warming yang and transporting fluids with Xianfu Shezi Decoction should be considered.Medication and dosage adjustments should be made based on the specific etiology,pathology,and related symptoms to improve the quality of male sperm and enhance the chances of conception.
